Abstract
Description
本発明は、椅子式階段昇降機用ガイドレール、即ち椅子付きの階段昇降機用のガイドレールと、その製造方法に関するものである。ガイドレールの製造及び階段への設置を容易・安価かつ精度良く行うと共に、階段へ設置後は、昇降機がスムーズに移動できるようにし、かつ高齢者等の利用者にも優しいものにすることを特徴としている。 The present invention relates to a guide rail for a chair type stair lift, that is, a guide rail for a stair lift with a chair, and a manufacturing method thereof. Manufacture of guide rails and installation on stairs is easy, inexpensive, and accurate, and after installation on stairs, the elevator can move smoothly and be friendly to users such as elderly people. It is said.
椅子式階段昇降機は、例えば足腰が弱った高齢者・病人等（以下高齢者等という）が自分の力で階段を昇り降りし難い場合に、階段に設置したガイドレールに沿って昇降する昇降機の椅子に座って、昇降することを可能とするものである。その階段昇降機に用いるガイドレールとしては従来より幾つかのものがある。 A chair-type stair lift, for example, is an elevator that moves up and down along a guide rail installed on a staircase when it is difficult for an elderly person, sick person, etc. (hereinafter referred to as an elderly person) who has weak legs to climb up and down by himself. It is possible to sit up and down in a chair. Conventionally, there are several guide rails used for the stair lift.
ガイドレールの内、特に階段の途中に曲がり部分があるような場所に設置するガイドレールとしては、例えば下記のようなものが提案されている。
イ）ガイドレールの断面形状が丸形状やダルマ形状のパイプを用いるものであって、従来よりこのようなパイプを用いたものが多く、例えば下記公報に記載のものがこれに当たる。
B) Pipes with a guide rail having a round or dharma shape are used, and there have been many pipes using such pipes, and for example, those described in the following publications.
ロ）本願発明に比較的に近いものの例として、長尺の横長板材を短手方向が垂直状になるように設置するものがあり、例えば下記の公報に記載のものがそれである。
ところが、従来の上記階段昇降機用ガイドレールには、次のような問題点があった。
ａ）上記特許文献１ないし３におけるパイプ製のガイドレールは、強度面や昇降機本体の椅子を水平かつ安定に保ち易いという利点はある。しかし、階段途中の踊り場の形状に対応して、ガイドレールを三次元的な傾斜湾曲状（螺旋状）に形成する必要がある場合には、その曲げ加工をスムーズに行うことが容易でなく、作業性も悪かった。
However, the conventional guide rails for stair elevators have the following problems.
a) The pipe-made guide rails in Patent Documents 1 to 3 have an advantage that the strength surface and the chair of the elevator body can be easily kept horizontal and stable. However, when it is necessary to form the guide rail in a three-dimensional inclined curved shape (spiral) corresponding to the shape of the landing stage in the middle of the stairs, it is not easy to smoothly perform the bending process, Workability was also poor.
また狭い横幅の階段では、ガイドレールの湾曲半径も小さくする必要があるが、通常用いられているパイプは直径が４５ないし４８．６ｍｍであるから、その湾曲半径を小さくするには限界があった。さらに特許文献２におけるように断面形状がダルマ形のパイプ製や、特許文献３のように２本のガイドレールを用いるもは、ガイドレールにラックギヤを組み込んだものが多いが、その製造は容易ではなくて製造コストが高くついた。
これらは、ガイドレールの断面形状が角形、Ｃ形やＨ形としたものについても、ほぼ同様のことが言える。
In the case of narrow width staircases, it is necessary to reduce the radius of curvature of the guide rail. However, since the diameter of the commonly used pipe is 45 to 48.6 mm, there is a limit to reducing the radius of curvature. . Further, although pipes with a cross-sectional shape as in Patent Document 2 and two guide rails as in Patent Document 3 are often used, rack gears are incorporated into the guide rails, but their manufacture is not easy. There was no production cost.
The same can be said for the guide rail whose cross-sectional shape is square, C-shaped or H-shaped.
ｂ）上記引用文献４のガイドレールは、横長状板材を短手方向が垂直状になるようにして長手方向へ接続し、その上縁部に丸パイプを一体化したものである。その側面の長手方向にはラックとしてのチエーンを設け、または等間隔状にラック歯を多数個形成して、そこに昇降機本体のスプロケットが噛合して、昇降可能としてある。 b) The guide rail of the above cited reference 4 is formed by connecting a horizontally long plate material in the longitudinal direction so that the lateral direction is vertical, and integrating a round pipe on the upper edge thereof. A chain as a rack is provided in the longitudinal direction of the side surface, or a large number of rack teeth are formed at equal intervals, and a sprocket of the elevator body is engaged therewith so that it can be moved up and down.
しかしこのガイドレールでは、各戸で異なる階段の形状に対応させるために、如何にして三次元的な傾斜湾曲部を形成するのか、その製造方法が明らかにされていない。またパイプと一体化したこのガイドレールを、階段の形状に対応して傾斜湾曲状に製造することや、階段の形状に上手く合致するように設置する作業も簡単ではない。特に階段が小さい湾曲状部をもつ場合には、製造が一層難しい。 However, in this guide rail, it is not clear how to form a three-dimensional inclined curved portion so as to correspond to different staircase shapes in each door. In addition, it is not easy to manufacture the guide rail integrated with the pipe into an inclined curved shape corresponding to the shape of the stairs or to install the guide rail so as to match the shape of the stairs well. Manufacturing is more difficult especially when the staircase has a small curved portion.
さらに上記ラックとして、ガイドレールの側面にチエーンまたはラック歯を設けているので、ガイドレールの水平状湾曲や傾斜湾曲状が小さい湾曲半径になっている位置では、チエーンが変形したり、ラック歯の形成が難しかったり、またスプロケットとの噛合がスムーズにいかなくなったりしてしまう問題点が残っている。 Further, as the rack described above, a chain or a rack tooth is provided on the side surface of the guide rail. Therefore, at a position where the horizontal curvature or the inclined curvature of the guide rail has a small curvature radius, the chain is deformed or the rack tooth is There remains a problem that formation is difficult and meshing with the sprocket is not smoothly performed.
ｃ）他方、引用文献５のガイドレールは、長尺の長板材を短手方向が垂直状になるようにして用いる点では、上記特許文献４に記載のものと共通部分があると言える。しかしこのガイドレールも、各戸で異なる階段の形状に対応して、どのようにして三次元的な傾斜湾曲状に形成するのかについて、その手段が全く記載されておらず示唆も無い。それゆえに、やはり実現性があるのかとの疑問がある。 c) On the other hand, it can be said that the guide rail of the cited document 5 has a common part with the thing described in the said patent document 4 by the point which uses a elongate long board | plate material so that a transversal direction may become perpendicular | vertical. However, this guide rail is not described or suggested at all as to how it is formed into a three-dimensional inclined curved shape corresponding to the shape of different stairs in each door. Therefore, there is a question as to whether it is feasible.
またこのガイドレールでは、その上縁部または下縁部にラック部を形成して、そこに昇降機本体のピニオンを噛合させて移動可能とし、かつガイドレールの上縁部または下縁部にガイドローラが接するように設けてある。そのため、昇降機本体がこのガイドレール上を移動時に昇降機本体に振動が伝わって乗り心地が悪いし、またレールの水平状湾曲部や傾斜湾曲部では、ラック部とスプロケットとの噛合状態が悪くなることも推測される。 Further, in this guide rail, a rack portion is formed at the upper edge portion or the lower edge portion of the guide rail so that the pinion of the elevator body can be engaged therewith, and the guide roller can be moved at the upper edge portion or the lower edge portion of the guide rail. Is provided to touch. Therefore, when the elevator main body moves on this guide rail, vibration is transmitted to the elevator main body and the riding comfort is bad, and in the horizontal curved portion and the inclined curved portion of the rail, the meshing state of the rack portion and the sprocket becomes poor. Also guessed.
本発明は、従来の上記椅子式階段昇降機用ガイドレールがもつ上記問題点の解消を課題としたものである。即ち本発明の主たる目的は、各戸で異なる階段の形状に対応した上・下段部の直線傾斜状部・傾斜湾曲部等をもつガイドレールを、容易・安価かつ精度良く製造できると共に、階段への設置作業も容易かつ安価に行え、さらに無理なくスムーズに移動できて、高齢者等の利用者の不安感を除いた、優しい階段昇降機用ガイドレールを提供することにある。 An object of the present invention is to eliminate the above-mentioned problems of the conventional guide rail for a chair type stair lift. That is, the main object of the present invention is to easily and inexpensively manufacture a guide rail having a linearly inclined portion and an inclined curved portion of the upper and lower steps corresponding to the shape of different stairs in each door, and to the stairs. It is an object of the present invention to provide a gentle guide rail for a stair lift that can be installed easily and inexpensively, can be moved smoothly and smoothly, and eliminates the anxiety of users such as elderly people.
Ａ 本発明に係る椅子式階段昇降機用ガイドレール１は、
複数枚の横長状板材３，４，５を長手方向へ接続して長尺としたものを、短手方向が垂直状になるようにして、階段２に沿って傾斜・湾曲させながら設置するものであり、
その長手方向には、少なくとも下部段用の直線傾斜状部６、踊り場１０用の傾斜湾曲状部７、上部段用の直線傾斜状部８等を有すると共に、
側面に長手方向へ、昇降機本体側に設けた駆動用ローラ周部の等間隔状の凸部と噛合可能な四角孔９を等間隔状で多数個有し、
かつ、上記湾曲傾斜状部７は、長手方向に「ヘ」の字状に屈曲した形状に切断形成した横長状板材４を湾曲形成したものを用いて、設置状態時に湾曲傾斜状部７の途中で傾斜角が浅くなるように形成したことにより、
上段部における階段上面２ｂと直線状傾斜部８との間隔ｎが、下段部での同様の間隔ｍとほぼ同一になるようにしたものである。

By inputting those data into a laser processing machine, the above-mentioned horizontally long plate materials 3, 4 and 5 are divided and formed by laser processing from a steel plate material,
Thereafter, the horizontally long plate material 4 for the curved inclined portion 7 is slanted on the cylindrical body 11 to bend and formed into a curved inclined shape,
It is connected in the longitudinal direction to each of the horizontally long plate members 3, 5 for the linearly inclined portion of the upper and lower steps, and at least the linearly inclined portion 6, the curved inclined portion 7, and the upper portion of the upper stage A long guide rail 1 having a linearly inclined portion 8 is provided.
上記構成において、ガイドレール１は、少なくとも下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７・上部段用の直線傾斜状部８を有するが、それらは基本的な単位部分であって、それ以外の部分を有さない意味ではない。例えば、下部段用の直線傾斜状部６の前部に水平状部１２を有したり、上部段用の直線傾斜状部８の後部にも水平状部１３を有したり、図示は省略するが踊り場１０用の水平湾曲状部を有したりしてもよい。 In the above configuration, the guide rail 1 has at least a linear inclined portion 6 for a lower stage, a curved inclined portion 7 for a landing, and a linear inclined portion 8 for an upper stage, which are basic unit parts. It does not mean that it has no other parts. For example, the horizontal portion 12 is provided at the front of the linear inclined portion 6 for the lower stage, the horizontal portion 13 is also provided at the rear of the linear inclined portion 8 for the upper stage, and illustration is omitted. May have a horizontal curved portion for the landing 10.
湾曲傾斜状部７とは、傾斜しながら湾曲する部分、即ち、螺旋形の一部をなすように、傾斜しながら湾曲する３次元的に形成した部分を意味する。 The curved inclined portion 7 means a portion that is curved while being inclined, that is, a portion that is three-dimensionally curved while being inclined so as to form a part of a spiral shape.
本発明に係る階段昇降機用ガイドレール、およびその製造方法によれば、鉄製平板から、各戸で異なる階段の形状に対応して、少なくとも下部段用の直線傾斜状部６、湾曲傾斜状部７、上部段用の直線傾斜状部８等の基本的部分を備えたがイドレール１を、容易・安価かつ精度良く製造できると共に、各戸で異なる階段への設置作業も容易・迅速かつ安価に行え、しかも無理のないスムーズな昇降で高齢者等の利用者に一層優しい階段昇降機を得ることができる。 According to the stair lift guide rail and the manufacturing method thereof according to the present invention, at least the straight slope portion 6 for the lower step, the curved slope portion 7, Although equipped with basic parts such as the linearly inclined part 8 for the upper step, the id rail 1 can be manufactured easily, inexpensively and accurately, and can be easily, quickly and inexpensively installed on different stairs in each door. It is possible to obtain a stair lift that is gentler to users such as elderly people by smooth elevating without difficulty.
イ）まず、本発明に係る階段昇降機用ガイドレールを製造方法から述べると、その前半工程は、受注後に置いてこのガイドレール１を設置する階段の形状・寸法・傾斜角等を実測し、その実測値に基づき２次元および３次元ＣＡＤシテスムを用いて、上記下段部用の直線傾斜状部６、踊り場１０用の湾曲傾斜状部７、上部段用の直線傾斜状部８の各展開図を作成し、そのデータをレーザー加工機に入力して、鉄製平板から上記各部に対応する各横長状板材３，４，５を分割形成することである。また同時にレーザー加工にて、各横長状板材３，４，５の側面に、駆動用として等間隔状に多数のラック用四角孔９も形成しておく。 B) First, the manufacturing method of the guide rail for the stair lift according to the present invention will be described. In the first half of the process, the shape, dimensions, inclination angle, etc. of the staircase in which the guide rail 1 is installed after receiving the order are measured. Using the two-dimensional and three-dimensional CAD system based on the actually measured values, each development view of the linear inclined portion 6 for the lower step, the curved inclined portion 7 for the landing 10 and the linear inclined portion 8 for the upper step is shown. That is, the data is input to a laser processing machine, and each horizontally long plate material 3, 4, 5 corresponding to each of the above parts is dividedly formed from an iron flat plate. At the same time, a large number of rack square holes 9 are formed at equal intervals for driving on the side surfaces of the horizontally long plate members 3, 4 and 5 by laser processing.
なお、下部段用の直線傾斜状部６の前部や、上部段用の直線傾斜状部８の後部に水平状部１２，１３がある場合は、上記展開図の段階で既に各水平状となる部分が描かれており（例えば図４参照）、それをレーザー加工によりその部分も同時に形成された横長状板材３，５になっている（例えば図５，図７参照）。そのため、横長状板材を短手方向に曲げるような無理な加工は必要無いし、また水平状部だけを別途形成しておき後で直線傾斜状部に接続するような必要もなく、本発明に係るガイドレール１の製造は容易・迅速かつ精度よく行える。 In addition, when there are horizontal portions 12 and 13 at the front portion of the linear inclined portion 6 for the lower step and the rear portion of the linear inclined portion 8 for the upper step, each horizontal shape is already This portion is drawn (see, for example, FIG. 4), and is formed into a horizontally long plate material 3, 5 that is also formed by laser processing (see, for example, FIGS. 5 and 7). Therefore, it is not necessary to perform excessive processing such as bending the horizontally long plate material in the short direction, and it is not necessary to separately form only the horizontal portion and connect to the linear inclined portion later. Manufacture of such a guide rail 1 can be performed easily, quickly and accurately.
これで、各戸の階段で異なる寸法・形状・傾斜角等の条件に対応すると共に側面にラック用四角孔９付きの、ガイドレール構成材としての複数枚の横長状板材３，４，５を、容易・迅速かつ精度よく製造できることになる。 Now, a plurality of horizontally long plate materials 3, 4, and 5 as guide rail constituent materials corresponding to conditions such as different dimensions, shapes, inclination angles, etc. in the stairs of each door and having rack square holes 9 on the side surfaces, It will be easy, quick and accurate.
ロ）次に、本発明に係るガイドレールを製造する後半工程は、各戸で異なる階段２の寸法・形状に併せて立体的に形成することである。上記の如く鉄製平板をレーザー加工で各部の展開図に対応して複数枚の横長状板材３，４，５を分割形成してあるから、それを階段の各部に応じた形状に加工すればよい。 B) Next, the second half of the process for manufacturing the guide rail according to the present invention is to form three-dimensionally in accordance with the size and shape of the different stairs 2 at each door. As described above, a plurality of horizontally long plate members 3, 4, and 5 are dividedly formed by laser processing corresponding to the development of each part by laser processing, so that it may be processed into a shape corresponding to each part of the staircase. .
階段の踊り場１０に対応するには、ガイドレール１を湾曲傾斜状に形成する必要があるが、この場合に、本発明の製造方法では、平板から形成した横長状板材４をベンダーで円筒体１１に斜めに捲きかけて厚み方向へ湾曲形成すればよい（例えば図８参照）。そのため、従来のパイプ状のレール（例えば上記特許文献１，同２，同３参照）や、一部にパイプをもつレール（上記特許文献４参照）と異なり、この湾曲作業は非常に容易であるし、湾曲半径を小さくすることも容易に行えるから、狭い階段でも省スペースで設置可能なガイドレールになる。 In order to correspond to the stair landing 10, the guide rail 1 needs to be formed in a curved inclined shape. In this case, in the manufacturing method of the present invention, the horizontally long plate material 4 formed from a flat plate is used as a cylinder 11 by a bender. It is only necessary to form a curve in the thickness direction by slanting over (see, for example, FIG. 8). Therefore, unlike conventional pipe-shaped rails (for example, see Patent Documents 1, 2, and 3 above) and rails having a pipe in part (see Patent Document 4 above), this bending work is very easy. In addition, since the radius of curvature can be easily reduced, the guide rail can be installed in a small space even on narrow stairs.
ガイドレール１としての下部・上部段用の各直線傾斜状部６，８や湾曲傾斜状部７等用の各横長板状材３，４，５等を形成した後は、それらを短手方向が垂直状になる状態で、階段の形状に応じて長手方向へ接続すればよい。これにより形成されたガイドレール１の側面には、各横長板材３，４，５の段階で予め側面に等間隔状の多数のラック用四角孔９も形成されているから、別途改めて駆動用のラックなどの機構をガイドレール１に設ける必要がなく、この面でも製造が容易になっている。 After forming each of the horizontally long plate-shaped members 3, 4, 5 and the like for the straight inclined portions 6 and 8 for the lower and upper steps as the guide rail 1 and the curved inclined portion 7 and the like, In such a state that is vertical, it may be connected in the longitudinal direction according to the shape of the stairs. On the side surface of the guide rail 1 formed in this manner, a large number of equally spaced square holes 9 for racks are formed on the side surface in advance at the stage of each of the horizontally long plate members 3, 4, 5. There is no need to provide a mechanism such as a rack on the guide rail 1, and this aspect also facilitates manufacturing.
ハ）さらに本発明のガイドレール１には、上記に加えて高齢者等の利用者に優しいという効果がある。即ち、階段に踊り場１０があって、そこにガイドレール１の湾曲傾斜状部７を設置する場合に、踊り場１０で折り返して上部段用の直線傾斜状部８へさしかかった位置近傍では、図９で示すような状態になる。その際、湾曲傾斜状部７が、仮に図１０で示すような直線状の横長板材４を湾曲形成したものである場合（図面符号は本願のものと一致させてある）は、同図９の二点鎖線で示すように、上部階段の上面２ｂからガイドレール１の直線傾斜状部８下端縁までの高さｌが、下段階段の上面２ａからガイドレール１の直線傾斜状部６までの高さｍに比べて大きくなってしまっていた。これでは昇降機の椅子に座った高齢者等の利用者は不安感を覚える。 C) In addition to the above, the guide rail 1 of the present invention has the effect of being friendly to users such as elderly people. That is, when there is a landing 10 on the stairs and the curved inclined portion 7 of the guide rail 1 is installed there, in the vicinity of the position where it is folded back at the landing 10 and approaches the linear inclined portion 8 for the upper stage, FIG. It will be in the state shown in. At that time, if the curved inclined portion 7 is formed by bending a linear horizontally long plate material 4 as shown in FIG. 10 (the reference numerals are the same as those in the present application), As indicated by the two-dot chain line, the height l from the upper surface 2b of the upper staircase to the lower edge of the linearly inclined portion 8 of the guide rail 1 is the height from the upper surface 2a of the lower step to the linearly inclined portion 6 of the guide rail 1. It was larger than the length m. With this, users such as elderly people sitting on the chair of the elevator feel anxious.
これに対して、本発明のガイドレール１の湾曲傾斜状部７で用いた横長状板材４は、その長手方向の途中で「ヘ」の字状に屈曲した形状にレーザー加工で切り抜いたもの（例えば図６参照）を、湾曲形成したものである。そのため、この傾斜状湾曲部７をもつカイドレール１を設置すると、該湾曲傾斜状部７はその途中からその傾斜角が浅い方向へ曲がるように設けられる。即ち、図９の実線で示す如く、上段部で階段上面２ｂから直線傾斜状部８下端縁までの間隔ｎは、下段部で階段上面２ａから直線上傾斜部６下端縁までの間隔ｍとほぼ等しくなっており、その状態で上段の直線傾斜状部８が継続している。 On the other hand, the horizontally long plate 4 used in the curved inclined portion 7 of the guide rail 1 of the present invention is cut out by laser processing into a shape bent in a “f” shape in the middle of the longitudinal direction ( For example, see FIG. 6). Therefore, when the guide rail 1 having the inclined curved portion 7 is installed, the curved inclined portion 7 is provided such that the inclined angle is bent in a shallow direction from the middle. That is, as shown by the solid line in FIG. 9, the distance n from the upper surface 2b of the upper step portion to the lower edge of the linearly inclined portion 8 is substantially the same as the interval m from the upper surface 2a of the stepped portion 2a to the lower edge of the linearly inclined portion 6 at the lower step portion. In this state, the upper straight slope portion 8 continues.
このように、上部段で階段上面２ｂから直線形状状部８までの高さｎが、下部段での階段上面２ａから直線傾斜状部６までの高さｍとほぼ等しいことにより、昇降機本体の椅子に座って昇降する高齢者等の利用者は無理のないスムーズな昇降ができて、違和感・不安感を与えることがなくなり、彼らに優しい階段昇降機用ガイドレールとなっている。 As described above, the height n from the upper surface 2b of the staircase top surface 2b to the linearly shaped portion 8 at the upper stage is substantially equal to the height m from the upper surface 2a of the staircase 2a to the linearly inclined portion 6 at the lower stage. Users such as elderly people who are sitting on chairs can move up and down smoothly without any uncomfortable feeling and anxiety, and they are friendly guide rails for stair lifts.
ニ）なお、図示は省略したが、ガイドレール１を階段の内回り部分に設置する場合で、その部分での傾斜角を大きくする必要があるなら、上記傾斜湾曲状部７用の横長状板材７を上下逆向きにして、逆「ヘ」の字状となったものを湾曲形成すればよい。その場合の傾斜湾曲状部７は、例えば図１０で示すような直線状の横長状板材を用いる場合よりも傾斜角が大きくなるから、階段のその部分に対応できるようになる。またこの場合に、駆動用にチエーンを固着したり凹凸したラック部を反対面に設けたものと異なり、上記駆動用四角孔９表裏いずれからも利用可能である。 D) Although not shown in the drawings, if the guide rail 1 is installed in the inner part of the stairs and it is necessary to increase the inclination angle at that part, the horizontally long plate 7 for the inclined curved part 7 is used. Is turned upside down, and an inverted “f” shape may be curved. In this case, the inclined curved portion 7 has a larger inclination angle than the case where a linear horizontally long plate as shown in FIG. 10 is used, for example, so that it can correspond to that portion of the staircase. Further, in this case, unlike the case in which a chain is fixed for driving or an uneven rack portion is provided on the opposite surface, the driving square hole 9 can be used from both the front and back sides.
本発明に係る階段昇降機用ガイドレールは、設置する階段の形状・寸法・傾斜角等に応じて、２次元ＣＡＤと３次元ＣＡＤシステムを用いて鉄製の平板材から、少なくとも下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７・上部段用の直線傾斜状部８等用の複数枚の横長状板材３，４，５を形成し、それらを長手方向へ接続して長尺としたものを短手方向が垂直状になるようにして、階段２に沿って傾斜・湾曲させながら設置可能としたものである。また上記湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状に切断形成したものを、円筒体に斜め状に捲きかけて湾曲形成したものを用いる。 The guide rail for the stair elevator according to the present invention is a linear inclination for at least a lower step from an iron flat plate using a two-dimensional CAD and a three-dimensional CAD system according to the shape, size, inclination angle, etc. of the installed staircase. Forming a plurality of horizontally long plate members 3, 4, and 5 for a curved portion 6, a curved sloping portion 7 for a landing, a straight sloping portion 8 for an upper stage, etc., and connecting them in the longitudinal direction This can be installed while being inclined and curved along the stairs 2 so that the lateral direction is vertical. In addition, the horizontally long plate member 4 for the curved inclined portion 7 is formed by cutting the cylindrical body into a shape bent in the shape of a letter “H” in the longitudinal direction and bending it in a slanting manner on a cylindrical body. Is used.
図１ないし図９は、本発明に係る椅子式階段昇降機用ガイドレールとその製造方法の実施例を示すものである。
このガイドレール１は、設置する階段２の寸法・形状・傾斜角等に対応する複数枚の横長状板材３，４，５を、短手方向が垂直状になるようにして長手方向へ接続して長尺としたものであり、その側面に、駆動用のラック用四角孔を等間隔状で多数個形成してある。また該ガイドレール１の内の湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状のものを、円筒体１１に斜め状に捲きかけて形成したものを用いている。
FIG. 1 thru | or FIG. 9 shows the Example of the guide rail for chair type stairlifts which concerns on this invention, and its manufacturing method.
This guide rail 1 connects a plurality of horizontally long plates 3, 4, and 5 corresponding to the size, shape, inclination angle, etc. of the stairs 2 to be installed in the longitudinal direction so that the short direction is vertical. A plurality of square holes for driving racks are formed at equal intervals on the side surface. Further, the horizontally long plate member 4 for the curved inclined portion 7 in the guide rail 1 is slanted to the cylindrical body 11 in a slanted shape in the middle in the longitudinal direction. The formed one is used.
その形状が理解し易いように、このガイドレール１の製造方法から説明する。予め、ガイドレール１を設置しようとする階段の形状・寸法・傾斜角等を実測しておき、その実測値を２次元ＣＡＤシステムを用いて２次元化したデータを得る。そのデータより作成さたるものを図１・図２で示す。なおここでのガイドレール１は、下部段用の直線傾斜状部６や上部段用の直線傾斜状部８に、各々水平状部１２，１３を有するものにしてある。 In order to make the shape easy to understand, the manufacturing method of the guide rail 1 will be described. The shape, dimensions, inclination angle, etc. of the stairs where the guide rail 1 is to be installed are measured in advance, and the measured values are two-dimensionalized using a two-dimensional CAD system. The data created from the data is shown in FIGS. In this case, the guide rail 1 has horizontal portions 12 and 13 on the linearly inclined portion 6 for the lower stage and the linearly inclined portion 8 for the upper stage, respectively.
次に、上記２次元化したデータを更に３次元ＣＡＤシステムを用いて３次元化すると共に、設置する階段用のガイドレール１となるように、下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７、および上部段用の直線傾斜状部８とするための各横長状板材３，４，５用のデータと、鉄製平板材から分割形成するための適切な分割箇所、即ち後の接続箇所１８のデータも得る。そのデータにより表示したガイドレール全体の展開図を図４で示す。 Next, the above two-dimensional data is further three-dimensionalized by using a three-dimensional CAD system, and the lower-level linear inclined portion 6 and the landing stage so as to become the guide rail 1 for the staircase to be installed. Data for each of the horizontally long plate members 3, 4 and 5 for forming the curved inclined portion 7 and the linear inclined portion 8 for the upper stage, and an appropriate divided portion for dividing and forming from the steel flat plate material, that is, the rear The data of the connection point 18 is also obtained. FIG. 4 shows a developed view of the entire guide rail displayed by the data.
さらに上記湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状になるように考慮してある。この「へ」の字の傾斜角αは、ここでは図６で示すように約１０°位になるようにしておく。なお、ここで用いた２次元ＣＡＤや３次元ＣＡＤシステムは、機器は米国ダッソー・システムズ・ソリッドワークス社製で、ソフトはソリッドワークス社製の三次元ＣＡＤソフトを用いた。 Further, the horizontally long plate member 4 for the curved inclined portion 7 is considered so as to be bent in the shape of a “f” in the longitudinal direction. In this case, the inclination angle α of the letter “he” is about 10 ° as shown in FIG. The 2D CAD system and the 3D CAD system used here were manufactured by Dassault Systèmes Solid Works, Inc., and the software used was 3D CAD software manufactured by Solid Works.
次に、上記３次元ＣＡＤシステムによるデータをＮＣレーザー加工機に入力して、鉄製平板材から下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７、上部段用の直線傾斜状部８となる各横長状板材３，４，５を切断形成する。同時に、この各横長状板材３，４，５の側面には、長手方向へ等間隔状に、駆動用ラックとしての四角孔９も多数個形成しておく。 Next, data from the above three-dimensional CAD system is input to an NC laser processing machine, and from a steel plate material, a straight slope 6 for a lower stage, a curved slope 7 for a landing, and a straight slope for an upper stage. Each horizontally long plate material 3, 4 and 5 to be the portion 8 is cut and formed. At the same time, a large number of square holes 9 as drive racks are formed on the side surfaces of the horizontally long plate members 3, 4 and 5 at equal intervals in the longitudinal direction.
該四角孔９は、該ガイドレール１に沿って移動する昇降機本体側の駆動用ローラ周部の等間隔の凸部が、順次に噛合可能な大きさ・形状であるが、その縦寸法はレールの縦曲がり部分で凸部が余裕をもって噛合可能なものに形成しておく。ここでは、鉄製平板材として、高張力鋼材のＳＭ５７０（新日鉄製）で、厚み９ｍｍ，幅１５０ｍｍの平板材を用いた。 The square hole 9 is sized and shaped so that the equally-spaced convex portions of the peripheral portion of the driving roller on the elevator body moving along the guide rail 1 can be sequentially meshed. It is formed in such a way that the convex part can be meshed with a margin at the vertical bending part. Here, as a steel flat plate, a high strength steel SM570 (manufactured by Nippon Steel), a flat plate having a thickness of 9 mm and a width of 150 mm was used.
なお、上記の下部段用の直線傾斜状部６となる横長状板材３や、上部段用の直線傾斜状部８となる横長状板材５は、階段へ設置時に各々水平状部１２，１３が連続形成されるように、図６で示す如く前者３の前部位置や後者５の後部位置を、逆「へ」の字状や「ヘ」の字状に曲がった部分に切断形成してある。なお、湾曲傾斜状部用の横長状板材４には、後にベンダーで湾曲状に曲げる際の曲げ位置もマーキングしておく（上記図６参照）。 Note that the horizontally long plate member 3 that becomes the linearly inclined portion 6 for the lower step and the horizontally long plate member 5 that becomes the linearly inclined portion 8 for the upper step have the horizontal portions 12 and 13 respectively when installed on the stairs. As shown in FIG. 6, the front position of the former 3 and the rear position of the latter 5 are cut and formed in a portion bent in a reverse “he” shape or “f” shape as shown in FIG. 6. . In addition, the bending position at the time of bending in a curved shape by a bender later is also marked on the horizontally long plate member 4 for the curved inclined portion (see FIG. 6 above).
さらに上記湾曲傾斜状部７となる横長状板材４は、長手方向の途中位置から長手方向に「ヘ」の字状に屈曲した形状に切断して形成したものを用いる。ここで、「ヘ」の字状の屈曲の程度は、上記の如く長手方向に約１０°の傾斜角がつくように形成してある。この横長状板材４を湾曲傾斜状に形成するには、図８で示す如く、専用ベンダーの円筒体１１に、その軸線に対して斜め状に捲きかけて厚み方向へ曲げて、湾曲傾斜状に形成する。 Further, the horizontally long plate material 4 that becomes the curved inclined portion 7 is formed by cutting into a shape bent in the shape of a letter “F” in the longitudinal direction from a middle position in the longitudinal direction. Here, the degree of bending of the “F” shape is formed so as to have an inclination angle of about 10 ° in the longitudinal direction as described above. In order to form the horizontally long plate material 4 in a curved inclined shape, as shown in FIG. 8, the cylindrical body 11 of the dedicated bender is slanted with respect to its axis, bent in the thickness direction, and bent in a curved inclined shape. Form.
次に、上記の如く形成した下段部の直線湾曲状部６用の横長状部材３、湾曲傾斜状部７用の横長状部材４、上段部の直線傾斜状部８用の横長状部材５を、短手方向が垂直状になるようにして長手方向へ接続することで長尺とし、それを階段２へ設置すればよい。これら各横長状部材３，４，５の接続には、ここでは裏面に保持板（図示略）を設けてネジ止めで行っている。１４は各横長状板材３，４，５の接続部を示す。 Next, the horizontally long member 3 for the linearly curved portion 6 of the lower step portion, the horizontally long member 4 for the curved inclined portion 7 and the horizontally long member 5 for the linearly inclined portion 8 of the upper portion formed as described above. It is only necessary to connect to the longitudinal direction so that the short direction is vertical, and to install it on the stairs 2. In order to connect these horizontally long members 3, 4, and 5, here, a holding plate (not shown) is provided on the back surface and is screwed. Reference numeral 14 denotes a connecting portion of each horizontally long plate member 3, 4, 5.
上記のように形成したガイドレール１を階段に設置した場合、特に踊り場１０における湾曲傾斜状部７は、上記の如く「へ」の字状の横長状部材を湾曲形成したものであるから、図９の実線で示すように、上部段における階段上面２ｂから直線状傾斜部８下端面までの間隔ｎは、下部段における階段上面２ａから直線状傾斜部６下端面までの間隔ｍとほぼ等しくなっている。湾曲傾斜部７を形成した横長状部材４が、「へ」の字状でなくて仮に直線状のものを湾曲形成した場合には、同図で二点鎖線で示すように、踊り場１０で湾曲傾斜すると床面との傾斜角が大きくなって、上部段の直線状傾斜部６に接続されるから、両者の差は明らかである。 When the guide rail 1 formed as described above is installed on a staircase, the curved inclined portion 7 particularly in the landing 10 is formed by bending a horizontally long member in the shape of a letter “he” as described above. As indicated by the solid line 9, the distance n from the upper surface 2 b of the upper step to the lower end surface of the linear inclined portion 8 is substantially equal to the distance m from the upper surface 2 a of the step to the lower end surface of the linear inclined portion 6. ing. When the horizontally long member 4 that forms the curved inclined portion 7 is not shaped like a letter "H" but is linearly curved, it is curved at the landing 10 as shown by a two-dot chain line in FIG. When tilted, the tilt angle with the floor surface increases and is connected to the linear slope 6 in the upper stage, so the difference between them is clear.
このように、本発明のガイドレール１によれば、上段部での階段上面２ｂの高さｎが、下段部での階段団面２ａとの高さｍとほぼ等しい状態で連続しているから、無理なくスムーズな昇降移動が可能となり、椅子に座って該ガイドレール１上を昇降する高齢者その他の利用者は不安感を覚えなくなる。 Thus, according to the guide rail 1 of the present invention, the height n of the upper surface 2b of the staircase at the upper step is continuous in a state substantially equal to the height m of the staircase surface 2a at the lower step. Therefore, it is possible to move up and down smoothly without difficulty, and elderly people and other users who sit on a chair and move up and down on the guide rail 1 do not feel uneasy.
なお、このガイドレール１には、上記駆動用四角孔９に干渉しない位置に、長手方向への等間隔状に補強用横リブ１５を設けてあり、また短手方向への補強用縦リブ１６も設けてあり、上記補強用横リブ１５には階段への取付脚を設ければよい。上記実施例中で示した材質・寸法・角度等の数値や、ＣＡＤの機種名・ソフト等は例示であって、これに限定するものでないことは勿論である。 The guide rail 1 is provided with reinforcing horizontal ribs 15 at equal intervals in the longitudinal direction at positions not interfering with the driving square holes 9, and reinforcing vertical ribs 16 in the short direction. The reinforcing lateral rib 15 may be provided with a leg for attachment to the staircase. Of course, the numerical values such as the material, dimension, angle, etc., CAD model name, software, etc. shown in the above embodiments are merely examples, and the present invention is not limited thereto.
本発明は、椅子式階段昇降機用のガイドレールであり、鉄製平板材から、各戸で異なる階段の形状に対応した直線傾斜状部６・水平湾曲状部・三次元形状の湾曲傾斜部等からなるガイドレールを、容易かつ安価で精度良く製造できると共に、階段への設置作業も容易・迅速かつ安価に行うことができ、しかも高齢者等の利用者に優しいものにすることができる。 The present invention is a guide rail for a chair type stair lift, and is composed of an iron flat plate, a linearly inclined portion 6 corresponding to different staircase shapes at each door, a horizontal curved portion, a three-dimensional curved inclined portion, and the like. The guide rail can be manufactured easily, inexpensively and with high accuracy, and can be easily and quickly installed at a low cost, and can be made easy for users such as elderly people.

本発明は、椅子式階段昇降機用ガイドレール、即ち椅子付きの階段昇降機用のガイドレールの製造方法に関するものである。ガイドレールの製造及び階段への設置を容易・安価かつ精度良く行うと共に、階段へ設置後は、昇降機がスムーズに移動できるようにし、かつ高齢者等の利用者にも優しいものにすることを特徴としている。 The present invention is a chair type stairlift guide rail, i.e. a method of manufacturing a guide rail of the chair with the stairlift. Manufacture of guide rails and installation on stairs is easy, inexpensive, and accurate, and after installation on stairs, the elevator can move smoothly and be friendly to users such as elderly people. It is said.
椅子式階段昇降機は、例えば足腰が弱った高齢者・病人等（以下高齢者等という）が自分の力で階段を昇り降りし難い場合に、階段に設置したガイドレールに沿って昇降する昇降機の椅子に座って、昇降することを可能とするものである。その階段昇降機に用いるガイドレールとしては従来より幾つかのものがある。 A chair-type stair lift, for example, is an elevator that moves up and down along a guide rail installed on a staircase when it is difficult for an elderly person, sick person, etc. (hereinafter referred to as an elderly person) who has weak legs to climb up and down by himself. It is possible to sit up and down in a chair. Conventionally, there are several guide rails used for the stair lift.
ガイドレールの内、特に階段の途中に曲がり部分があるような場所に設置するガイドレールとしては、例えば下記のようなものが提案されている。
イ）ガイドレールの断面形状が丸形状やダルマ形状のパイプを用いるものであって、従来よりこのようなパイプを用いたものが多く、例えば下記公報に記載のものがこれに当たる。
B) Pipes with a guide rail having a round or dharma shape are used, and there have been many pipes using such pipes, and for example, those described in the following publications.
ロ）本願発明に比較的に近いものの例として、長尺の横長板材を短手方向が垂直状になるように設置するものがあり、例えば下記の公報に記載のものがそれである。
ところが、従来の上記階段昇降機用ガイドレールには、次のような問題点があった。
ａ）上記特許文献１ないし３におけるパイプ製のガイドレールは、強度面や昇降機本体の椅子を水平かつ安定に保ち易いという利点はある。しかし、階段途中の踊り場の形状に対応して、ガイドレールを三次元的な傾斜湾曲状（螺旋状）に形成する必要がある場合には、その曲げ加工をスムーズに行うことが容易でなく、作業性も悪かった。
However, the conventional guide rails for stair elevators have the following problems.
a) The pipe-made guide rails in Patent Documents 1 to 3 have an advantage that the strength surface and the chair of the elevator body can be easily kept horizontal and stable. However, when it is necessary to form the guide rail in a three-dimensional inclined curved shape (spiral) corresponding to the shape of the landing stage in the middle of the stairs, it is not easy to smoothly perform the bending process, Workability was also poor.
また狭い横幅の階段では、ガイドレールの湾曲半径も小さくする必要があるが、通常用いられているパイプは直径が４５ないし４８．６ｍｍであるから、その湾曲半径を小さくするには限界があった。さらに特許文献２におけるように断面形状がダルマ形のパイプ製や、特許文献３のように２本のガイドレールを用いるもは、ガイドレールにラックギヤを組み込んだものが多いが、その製造は容易ではなくて製造コストが高くついた。
これらは、ガイドレールの断面形状が角形、Ｃ形やＨ形としたものについても、ほぼ同様のことが言える。
In the case of narrow width staircases, it is necessary to reduce the radius of curvature of the guide rail. However, since the diameter of the commonly used pipe is 45 to 48.6 mm, there is a limit to reducing the radius of curvature. . Further, although pipes with a cross-sectional shape as in Patent Document 2 and two guide rails as in Patent Document 3 are often used, rack gears are incorporated into the guide rails, but their manufacture is not easy. There was no production cost.
The same can be said for the guide rail whose cross-sectional shape is square, C-shaped or H-shaped.
ｂ）上記引用文献４のガイドレールは、横長状板材を短手方向が垂直状になるようにして長手方向へ接続し、その上縁部に丸パイプを一体化したものである。その側面の長手方向にはラックとしてのチエーンを設け、または等間隔状にラック歯を多数個形成して、そこに昇降機本体のスプロケットが噛合して、昇降可能としてある。 b) The guide rail of the above cited reference 4 is formed by connecting a horizontally long plate material in the longitudinal direction so that the lateral direction is vertical, and integrating a round pipe on the upper edge thereof. A chain as a rack is provided in the longitudinal direction of the side surface, or a large number of rack teeth are formed at equal intervals, and a sprocket of the elevator body is engaged therewith so that it can be moved up and down.
しかしこのガイドレールでは、各戸で異なる階段の形状に対応させるために、如何にして三次元的な傾斜湾曲部を形成するのか、その製造方法が明らかにされていない。またパイプと一体化したこのガイドレールを、階段の形状に対応して傾斜湾曲状に製造することや、階段の形状に上手く合致するように設置する作業も簡単ではない。特に階段が小さい湾曲状部をもつ場合には、製造が一層難しい。 However, in this guide rail, it is not clear how to form a three-dimensional inclined curved portion so as to correspond to different staircase shapes in each door. In addition, it is not easy to manufacture the guide rail integrated with the pipe into an inclined curved shape corresponding to the shape of the stairs or to install the guide rail so as to match the shape of the stairs well. Manufacturing is more difficult especially when the staircase has a small curved portion.
さらに上記ラックとして、ガイドレールの側面にチエーンまたはラック歯を設けているので、ガイドレールの水平状湾曲や傾斜湾曲状が小さい湾曲半径になっている位置では、チエーンが変形したり、ラック歯の形成が難しかったり、またスプロケットとの噛合がスムーズにいかなくなったりしてしまう問題点が残っている。 Further, as the rack described above, a chain or a rack tooth is provided on the side surface of the guide rail. Therefore, at a position where the horizontal curvature or the inclined curvature of the guide rail has a small curvature radius, the chain is deformed or the rack tooth is There remains a problem that formation is difficult and meshing with the sprocket is not smoothly performed.
ｃ）他方、引用文献５のガイドレールは、長尺の長板材を短手方向が垂直状になるようにして用いる点では、上記特許文献４に記載のものと共通部分があると言える。しかしこのガイドレールも、各戸で異なる階段の形状に対応して、どのようにして三次元的な傾斜湾曲状に形成するのかについて、その手段が全く記載されておらず示唆も無い。それゆえに、やはり実現性があるのかとの疑問がある。 c) On the other hand, it can be said that the guide rail of the cited document 5 has a common part with the thing described in the said patent document 4 by the point which uses a elongate long board | plate material so that a transversal direction may become perpendicular | vertical. However, this guide rail is not described or suggested at all as to how it is formed into a three-dimensional inclined curved shape corresponding to the shape of different stairs in each door. Therefore, there is a question as to whether it is feasible.
またこのガイドレールでは、その上縁部または下縁部にラック部を形成して、そこに昇降機本体のピニオンを噛合させて移動可能とし、かつガイドレールの上縁部または下縁部にガイドローラが接するように設けてある。そのため、昇降機本体がこのガイドレール上を移動時に昇降機本体に振動が伝わって乗り心地が悪いし、またレールの水平状湾曲部や傾斜湾曲部では、ラック部とスプロケットとの噛合状態が悪くなることも推測される。 Further, in this guide rail, a rack portion is formed at the upper edge portion or the lower edge portion of the guide rail so that the pinion of the elevator body can be engaged therewith, and the guide roller can be moved at the upper edge portion or the lower edge portion of the guide rail. Is provided to touch. Therefore, when the elevator main body moves on this guide rail, vibration is transmitted to the elevator main body and the riding comfort is bad, and in the horizontal curved portion and the inclined curved portion of the rail, the meshing state of the rack portion and the sprocket becomes poor. Also guessed.
本発明は、従来の上記椅子式階段昇降機用ガイドレールがもつ上記問題点の解消を課題としたものである。即ち本発明の主たる目的は、各戸で異なる階段の形状に対応した上・下段部の直線傾斜状部・傾斜湾曲部等をもつガイドレールを、容易・安価かつ精度良く製造できると共に、階段への設置作業も容易かつ安価に行え、さらに無理なくスムーズに移動できて、高齢者等の利用者の不安感を除いた、優しい階段昇降機用ガイドレールの製造方法を提供することにある。 An object of the present invention is to eliminate the above-mentioned problems of the conventional guide rail for a chair type stair lift. That is, the main object of the present invention is to easily and inexpensively manufacture a guide rail having a linearly inclined portion and an inclined curved portion of the upper and lower steps corresponding to the shape of different stairs in each door, and to the stairs. It is an object of the present invention to provide a method for manufacturing a gentle guide rail for a stair lift that can be installed easily and inexpensively, can be moved smoothly and smoothly, and eliminates the anxiety of users such as elderly people.

上記構成において、ガイドレール１は、少なくとも下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７・上部段用の直線傾斜状部８を有するが、それらは基本的な単位部分であって、それ以外の部分を有さない意味ではない。例えば、下部段用の直線傾斜状部６の前部に水平状部１２を有したり、上部段用の直線傾斜状部８の後部にも水平状部１３を有したり、図示は省略するが踊り場１０用の水平湾曲状部を有したりしてもよい。 In the above configuration, the guide rail 1 has at least a linear inclined portion 6 for a lower stage, a curved inclined portion 7 for a landing, and a linear inclined portion 8 for an upper stage, which are basic unit parts. It does not mean that it has no other parts. For example, the horizontal portion 12 is provided at the front of the linear inclined portion 6 for the lower stage, the horizontal portion 13 is also provided at the rear of the linear inclined portion 8 for the upper stage, and illustration is omitted. May have a horizontal curved portion for the landing 10.
湾曲傾斜状部７とは、傾斜しながら湾曲する部分、即ち、螺旋形の一部をなすように、傾斜しながら湾曲する３次元的に形成した部分を意味する。 The curved inclined portion 7 means a portion that is curved while being inclined, that is, a portion that is three-dimensionally curved while being inclined so as to form a part of a spiral shape.
本発明に係る階段昇降機用ガイドレールの製造方法によれば、鉄製平板から、各戸で異なる階段の形状に対応して、少なくとも下部段用の直線傾斜状部６、湾曲傾斜状部７、上部段用の直線傾斜状部８等の基本的部分を備えたがイドレール１を、容易・安価かつ精度良く製造できると共に、各戸で異なる階段への設置作業も容易・迅速かつ安価に行え、しかも無理のないスムーズな昇降で高齢者等の利用者に一層優しい階段昇降機を得ることができる。 According to the manufacturing method of the guide rail for stairlift according to the present invention, the iron plates to correspond to the shape of different stairs in parentheses, straight slanted portions 6 for at least a lower stage, the curved inclined portion 7, the upper Although equipped with basic parts such as a linearly inclined part 8 for steps, the idrail 1 can be manufactured easily, inexpensively and accurately, and can be easily, quickly and inexpensively installed on different stairs at each door. A smooth stair lift that is gentler to users such as the elderly can be obtained with smooth lift without any problems.
イ）まず、本発明に係る階段昇降機用ガイドレールを製造方法から述べると、その前半工程は、受注後に置いてこのガイドレール１を設置する階段の形状・寸法・傾斜角等を実測し、その実測値に基づき２次元および３次元ＣＡＤシテスムを用いて、上記下段部用の直線傾斜状部６、踊り場１０用の湾曲傾斜状部７、上部段用の直線傾斜状部８の各展開図を作成し、そのデータをレーザー加工機に入力して、鉄製平板から上記各部に対応する各横長状板材３，４，５を分割形成することである。また同時にレーザー加工にて、各横長状板材３，４，５の側面に、駆動用として等間隔状に多数のラック用の四角孔９も形成しておく。 B) First, the manufacturing method of the guide rail for the stair lift according to the present invention will be described. In the first half of the process, the shape, dimensions, inclination angle, etc. of the staircase in which the guide rail 1 is installed after receiving the order are measured. Using the two-dimensional and three-dimensional CAD system based on the actually measured values, each development view of the linear inclined portion 6 for the lower step, the curved inclined portion 7 for the landing 10 and the linear inclined portion 8 for the upper step is shown. That is, the data is input to a laser processing machine, and each horizontally long plate material 3, 4, 5 corresponding to each of the above parts is dividedly formed from an iron flat plate. At the same time, a large number of square holes 9 for racks are formed at equal intervals for driving on the side surfaces of the horizontally long plate members 3, 4 and 5 by laser processing.
なお、下部段用の直線傾斜状部６の前部や、上部段用の直線傾斜状部８の後部に水平状部１２，１３がある場合は、上記展開図の段階で既に各水平状となる部分が描かれており（例えば図４参照）、それをレーザー加工によりその部分も同時に形成された横長状板材３，５になっている（例えば図５，図７参照）。そのため、横長状板材を短手方向に曲げるような無理な加工は必要無いし、また水平状部だけを別途形成しておき後で直線傾斜状部に接続するような必要もなく、本発明に係るガイドレール１の製造は容易・迅速かつ精度よく行える。 In addition, when there are horizontal portions 12 and 13 at the front portion of the linear inclined portion 6 for the lower step and the rear portion of the linear inclined portion 8 for the upper step, each horizontal shape is already This portion is drawn (see, for example, FIG. 4), and is formed into a horizontally long plate material 3, 5 that is also formed by laser processing (see, for example, FIGS. 5 and 7). Therefore, it is not necessary to perform excessive processing such as bending the horizontally long plate material in the short direction, and it is not necessary to separately form only the horizontal portion and connect to the linear inclined portion later. Manufacture of such a guide rail 1 can be performed easily, quickly and accurately.
これで、各戸の階段で異なる寸法・形状・傾斜角等の条件に対応すると共に側面にラック用の四角孔９付きの、ガイドレール構成材としての複数枚の横長状板材３，４，５を、容易・迅速かつ精度よく製造できることになる。 Now, a plurality of horizontally long plate materials 3, 4, and 5 as guide rail constituent materials having a square hole 9 for the rack on the side surface and corresponding to conditions such as different dimensions, shapes, and inclination angles in the stairs of each door. It can be manufactured easily, quickly and accurately.
ロ）次に、本発明に係るガイドレールを製造する後半工程は、各戸で異なる階段２の寸法・形状に併せて立体的に形成することである。上記の如く鉄製平板をレーザー加工で各部の展開図に対応して複数枚の横長状板材３，４，５を分割形成してあるから、それを階段の各部に応じた形状に加工すればよい。 B) Next, the second half of the process for manufacturing the guide rail according to the present invention is to form three-dimensionally in accordance with the size and shape of the different stairs 2 at each door. As described above, a plurality of horizontally long plate members 3, 4, and 5 are dividedly formed by laser processing corresponding to the development of each part by laser processing, so that it may be processed into a shape corresponding to each part of the staircase. .
階段の踊り場１０に対応するには、ガイドレール１を湾曲傾斜状に形成する必要があるが、この場合に、本発明の製造方法では、平板から形成した横長状板材４をベンダーで円筒体１１に斜めに捲きかけて厚み方向へ湾曲形成すればよい（例えば図８参照）。そのため、従来のパイプ状のレール（例えば上記特許文献１，同２，同３参照）や、一部にパイプをもつレール（上記特許文献４参照）と異なり、この湾曲作業は非常に容易であるし、湾曲半径を小さくすることも容易に行えるから、狭い階段でも省スペースで設置可能なガイドレールになる。 In order to correspond to the stair landing 10, the guide rail 1 needs to be formed in a curved inclined shape. In this case, in the manufacturing method of the present invention, the horizontally long plate material 4 formed from a flat plate is used as a cylinder 11 by a bender. It is only necessary to form a curve in the thickness direction by slanting over (see, for example, FIG. 8). Therefore, unlike conventional pipe-shaped rails (for example, see Patent Documents 1, 2, and 3 above) and rails having a pipe in part (see Patent Document 4 above), this bending work is very easy. In addition, since the radius of curvature can be easily reduced, the guide rail can be installed in a small space even on narrow stairs.
ガイドレール１としての下部・上部段用の各直線傾斜状部６，８や湾曲傾斜状部７等用の各横長板状材３，４，５等を形成した後は、それらを短手方向が垂直状になる状態で、階段の形状に応じて長手方向へ接続すればよい。これにより形成されたガイドレール１の側面には、各横長板材３，４，５の段階で予め側面に等間隔状の多数のラック用の四角孔９も形成されているから、別途改めて駆動用のラックなどの機構をガイドレール１に設ける必要がなく、この面でも製造が容易になっている。 After forming each of the horizontally long plate-shaped members 3, 4, 5 and the like for the straight inclined portions 6 and 8 for the lower and upper steps as the guide rail 1 and the curved inclined portion 7 and the like, In such a state that is vertical, it may be connected in the longitudinal direction according to the shape of the stairs. The side surface of the guide rail 1 formed by this, because they are square holes 9 also formed for equally spaced like many rack advance side at the stage of the Horizontal plate member 3, 4, 5, drive separately again It is not necessary to provide a mechanism such as a rack in the guide rail 1, and this aspect also facilitates manufacture.
ハ）さらに、本発明の製造方法により製造したガイドレール１では、上記に加えて高齢者等の利用者に優しいという効果がある。即ち、そのガイドレール１を設置した場合に、階段に踊り場１０があって、そこにガイドレール１の湾曲傾斜状部７を設置する場合に、踊り場１０で折り返して上部段用の直線傾斜状部８へさしかかった位置近傍では、図９で示すような状態になる。その際、湾曲傾斜状部７が、仮に図１０で示すような直線状の横長板材４を湾曲形成したものである場合（図面符号は本願のものと一致させてある）は、同図９の二点鎖線で示すように、上部階段の上面２ｂからガイドレール１の直線傾斜状部８下端縁までの高さ（間隔）ｌが、下段階段の上面２ａからガイドレール１の直線傾斜状部６までの高さ（間隔）ｍに比べて大きくなってしまっていた。これでは昇降機の椅子に座った高齢者等の利用者は不安感を覚える。 C) Further , in addition to the above , the guide rail 1 manufactured by the manufacturing method of the present invention has an effect of being friendly to users such as elderly people. That is, when the guide rail 1 is installed and there is a landing 10 on the stairs and the curved inclined portion 7 of the guide rail 1 is installed there, the straight inclined portion for the upper stage is folded back at the landing 10. In the vicinity of the position approaching 8, the state is as shown in FIG. At that time, if the curved inclined portion 7 is formed by bending a linear horizontally long plate material 4 as shown in FIG. 10 (the reference numerals are the same as those in the present application), As indicated by a two-dot chain line, the height (interval ) 1 from the upper surface 2b of the upper staircase to the lower edge of the linearly inclined portion 8 of the guide rail 1 is equal to the linearly inclined portion 6 of the guide rail 1 from the upper surface 2a of the lower stage. It was larger than the height (interval ) m. With this, users such as elderly people sitting on the chair of the elevator feel anxious.
これに対して、本発明のガイドレール１の湾曲傾斜状部７で用いた横長状板材４は、その長手方向の途中で「ヘ」の字状に屈曲した形状にレーザー加工で切り抜いたもの（例えば図６参照）を、湾曲形成したものである。そのため、この傾斜状湾曲部７をもつカイドレール１を設置すると、該湾曲傾斜状部７はその途中からその傾斜角が浅い方向へ曲がるように設けられる。即ち、図９の実線で示す如く、上段部で階段上面２ｂから直線傾斜状部８下端縁までの高さ（間隔）ｎは、下段部で階段上面２ａから直線上傾斜部６下端縁までの高さ（間隔）ｍとほぼ等しくなっており、その状態で上段の直線傾斜状部８が継続している。 On the other hand, the horizontally long plate 4 used in the curved inclined portion 7 of the guide rail 1 of the present invention is cut out by laser processing into a shape bent in a “f” shape in the middle of the longitudinal direction ( For example, see FIG. 6). Therefore, when the guide rail 1 having the inclined curved portion 7 is installed, the curved inclined portion 7 is provided such that the inclined angle is bent in a shallow direction from the middle. That is, as indicated by the solid line in FIG. 9, the height (interval ) n from the upper surface 2b of the upper step portion to the lower edge of the linearly inclined portion 8 is from the upper surface 2a of the lower step portion to the lower edge of the upper linearly inclined portion 6. The height (interval ) m is substantially equal, and the upper straight inclined portion 8 continues in this state.
このように、上部段で階段上面２ｂから直線形状状部８までの高さｎが、下部段での階段上面２ａから直線傾斜状部６までの高さｍとほぼ等しいことにより、昇降機本体の椅子に座って昇降する高齢者等の利用者は無理のないスムーズな昇降ができて、違和感・不安感を与えることがなくなり、彼らに優しい階段昇降機用ガイドレールとなっている。 As described above, the height n from the upper surface 2b of the staircase top surface 2b to the linearly shaped portion 8 at the upper stage is substantially equal to the height m from the upper surface 2a of the staircase 2a to the linearly inclined portion 6 at the lower stage. Users such as elderly people who are sitting on chairs can move up and down smoothly without any uncomfortable feeling and anxiety, and they are friendly guide rails for stair lifts.
ニ）なお、図示は省略したが、ガイドレール１を階段の内回り部分に設置する場合で、その部分での傾斜角を大きくする必要があるなら、上記傾斜湾曲状部７用の横長状板材７を上下逆向きにして、逆「ヘ」の字状となったものを湾曲形成すればよい。その場合の傾斜湾曲状部７は、例えば図１０で示すような直線状の横長状板材を用いる場合よりも傾斜角が大きくなるから、階段のその部分に対応できるようになる。またこの場合に、駆動用にチエーンを固着したり凹凸したラック部を反対面に設けたものと異なり、上記駆動用四角孔９表裏いずれからも利用可能である。 D) Although not shown in the drawings, if the guide rail 1 is installed in the inner part of the stairs and it is necessary to increase the inclination angle at that part, the horizontally long plate 7 for the inclined curved part 7 is used. Is turned upside down, and an inverted “f” shape may be curved. In this case, the inclined curved portion 7 has a larger inclination angle than the case where a linear horizontally long plate as shown in FIG. 10 is used, for example, so that it can correspond to that portion of the staircase. Further, in this case, unlike the case in which a chain is fixed for driving or an uneven rack portion is provided on the opposite surface, the driving square hole 9 can be used from both the front and back sides.
本発明に係る階段昇降機用ガイドレールの製造方法は、設置する階段の形状・寸法・傾斜角等に応じて、２次元ＣＡＤと３次元ＣＡＤシステムを用いて鉄製の平板材から、少なくとも下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７・上部段用の直線傾斜状部８等用の複数枚の横長状板材３，４，５を形成し、それらを長手方向へ接続して長尺としたものを短手方向が垂直状になるようにして、階段２に沿って傾斜・湾曲させながら設置可能としたものである。また上記湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状に切断形成したものを、円筒体に斜め状に捲きかけて湾曲形成したものを用いる。 The method for manufacturing a guide rail for a stair lift according to the present invention is for at least a lower step from an iron flat plate using a two-dimensional CAD and a three-dimensional CAD system according to the shape, dimensions, inclination angle, etc. of the staircase to be installed. A plurality of horizontally long plate members 3, 4 and 5 are formed for a straight inclined portion 6, a curved inclined portion 7 for a landing, a linear inclined portion 8 for an upper stage, etc., and these are connected in the longitudinal direction. In this way, the long one can be installed while being inclined and curved along the stairs 2 so that the short direction is vertical. In addition, the horizontally long plate member 4 for the curved inclined portion 7 is formed by cutting the cylindrical body into a shape bent in the shape of a letter “H” in the longitudinal direction and bending it in a slanting manner on a cylindrical body. Is used.
図１ないし図９は、本発明に係る椅子式階段昇降機用ガイドレールの製造方法の実施例を示すものである。
このガイドレール１は、設置する階段２の寸法・形状・傾斜角等に対応する複数枚の横長状板材３，４，５を、短手方向が垂直状になるようにして長手方向へ接続して長尺としたものであり、その側面に、駆動用のラック用四角孔を等間隔状で多数個形成してある。また該ガイドレール１の内の湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状のものを、円筒体１１に斜め状に捲きかけて形成したものを用いている。
1 to 9 shows an embodiment of a chair-type stairlift guide rail manufacturing method according to the present invention.
This guide rail 1 connects a plurality of horizontally long plates 3, 4, and 5 corresponding to the size, shape, inclination angle, etc. of the stairs 2 to be installed in the longitudinal direction so that the short direction is vertical. A plurality of square holes for driving racks are formed at equal intervals on the side surface. Further, the horizontally long plate member 4 for the curved inclined portion 7 in the guide rail 1 is slanted to the cylindrical body 11 in a slanted shape in the middle in the longitudinal direction. The formed one is used.
その形状が理解し易いように、このガイドレール１の製造方法から説明する。予め、ガイドレール１を設置しようとする階段の形状・寸法・傾斜角等を実測しておき、その実測値を２次元ＣＡＤシステムを用いて２次元化したデータを得る。そのデータより作成さたるものを図１・図２で示す。なおここでのガイドレール１は、下部段用の直線傾斜状部６や上部段用の直線傾斜状部８に、各々水平状部１２，１３を有するものにしてある。 In order to make the shape easy to understand, the manufacturing method of the guide rail 1 will be described. The shape, dimensions, inclination angle, etc. of the stairs where the guide rail 1 is to be installed are measured in advance, and the measured values are two-dimensionalized using a two-dimensional CAD system. The data created from the data is shown in FIGS. In this case, the guide rail 1 has horizontal portions 12 and 13 on the linearly inclined portion 6 for the lower stage and the linearly inclined portion 8 for the upper stage, respectively.
次に、上記２次元化したデータを更に３次元ＣＡＤシステムを用いて３次元化すると共に、設置する階段用のガイドレール１となるように、下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７、および上部段用の直線傾斜状部８とするための各横長状板材３，４，５用のデータと、鉄製平板材から分割形成するための適切な分割箇所、即ち後の接続箇所１８のデータも得る。そのデータにより表示したガイドレール全体の展開図を図４で示す。 Next, the above two-dimensional data is further three-dimensionalized by using a three-dimensional CAD system, and the lower-level linear inclined portion 6 and the landing stage so as to become the guide rail 1 for the staircase to be installed. Data for each of the horizontally long plate members 3, 4 and 5 for forming the curved inclined portion 7 and the linear inclined portion 8 for the upper stage, and an appropriate divided portion for dividing and forming from the steel flat plate material, that is, the rear The data of the connection point 18 is also obtained. FIG. 4 shows a developed view of the entire guide rail displayed by the data.
さらに上記湾曲傾斜状部７用の横長状板材４は、途中で長手方向に「ヘ」の字状に屈曲した形状になるように考慮してある。この「へ」の字の傾斜角αは、ここでは図６で示すように約１０°位になるようにしておく。なお、ここで用いた２次元ＣＡＤや３次元ＣＡＤシステムは、機器は米国ダッソー・システムズ・ソリッドワークス社製で、ソフトはソリッドワークス社製の三次元ＣＡＤソフトを用いた。 Further, the horizontally long plate member 4 for the curved inclined portion 7 is considered so as to be bent in the shape of a “f” in the longitudinal direction. In this case, the inclination angle α of the letter “he” is about 10 ° as shown in FIG. The 2D CAD system and the 3D CAD system used here were manufactured by Dassault Systèmes Solid Works, Inc., and the software used was 3D CAD software manufactured by Solid Works.
次に、上記３次元ＣＡＤシステムによるデータをＮＣレーザー加工機に入力して、鉄製平板材から下部段用の直線傾斜状部６、踊り場用の湾曲傾斜状部７、上部段用の直線傾斜状部８となる各横長状板材３，４，５を切断形成する。同時に、この各横長状板材３，４，５の側面には、長手方向へ等間隔状に、ラック用としての四角孔９も多数個形成しておく。 Next, data from the above three-dimensional CAD system is input to an NC laser processing machine, and from a steel plate material, a straight slope 6 for a lower stage, a curved slope 7 for a landing, and a straight slope for an upper stage. Each horizontally long plate material 3, 4 and 5 to be the portion 8 is cut and formed. At the same time, the side surface of each horizontally long plate member 3, 4, 5, at regular intervals like in the longitudinal direction, keep a large number also formed rectangular hole 9 as a rack.
該四角孔９は、該ガイドレール１に沿って移動する昇降機本体側の駆動用ローラ周部の等間隔の凸部が、順次に噛合可能な大きさ・形状であるが、その縦寸法はレールの縦曲がり部分で凸部が余裕をもって噛合可能なものに形成しておく。ここでは、鉄製平板材として、高張力鋼材のＳＭ５７０（新日鉄製）で、厚み９ｍｍ，幅１５０ｍｍの平板材を用いた。 The square hole 9 is sized and shaped so that the equally-spaced convex portions of the peripheral portion of the driving roller on the elevator body moving along the guide rail 1 can be sequentially meshed. It is formed in such a way that the convex part can be meshed with a margin at the vertical bending part. Here, as a steel flat plate, a high strength steel SM570 (manufactured by Nippon Steel), a flat plate having a thickness of 9 mm and a width of 150 mm was used.
なお、上記の下部段用の直線傾斜状部６となる横長状板材３や、上部段用の直線傾斜状部８となる横長状板材５は、階段へ設置時に各々水平状部１２，１３が連続形成されるように、図６で示す如く前者３の前部位置や後者５の後部位置を、逆「へ」の字状や「ヘ」の字状に曲がった部分に切断形成してある。なお、湾曲傾斜状部用の横長状板材４には、後にベンダーで湾曲状に曲げる際の曲げ位置もマーキングしておく（上記図６参照）。 Note that the horizontally long plate member 3 that becomes the linearly inclined portion 6 for the lower step and the horizontally long plate member 5 that becomes the linearly inclined portion 8 for the upper step have the horizontal portions 12 and 13 respectively when installed on the stairs. As shown in FIG. 6, the front position of the former 3 and the rear position of the latter 5 are cut and formed in a portion bent in a reverse “he” shape or “f” shape as shown in FIG. 6. . In addition, the bending position at the time of bending in a curved shape by a bender later is also marked on the horizontally long plate member 4 for the curved inclined portion (see FIG. 6 above).
さらに上記湾曲傾斜状部７となる横長状板材４は、長手方向の途中位置から長手方向に「ヘ」の字状に屈曲した形状に切断して形成したものを用いる。ここで、「ヘ」の字状の屈曲の程度は、上記の如く長手方向に約１０°の傾斜角がつくように形成してある。この横長状板材４を湾曲傾斜状に形成するには、図８で示す如く、専用ベンダーの円筒体１１に、その軸線に対して斜め状に捲きかけて厚み方向へ曲げて、湾曲傾斜状に形成する。 Further, the horizontally long plate material 4 that becomes the curved inclined portion 7 is formed by cutting into a shape bent in the shape of a letter “F” in the longitudinal direction from a middle position in the longitudinal direction. Here, the degree of bending of the “F” shape is formed so as to have an inclination angle of about 10 ° in the longitudinal direction as described above. In order to form the horizontally long plate material 4 in a curved inclined shape, as shown in FIG. 8, the cylindrical body 11 of the dedicated bender is slanted with respect to its axis, bent in the thickness direction, and bent in a curved inclined shape. Form.
次に、上記の如く形成した下段部の直線湾曲状部６用の横長状部材３、湾曲傾斜状部７用の横長状部材４、上段部の直線傾斜状部８用の横長状部材５を、短手方向が垂直状になるようにして長手方向へ接続することで長尺とし、それを階段２へ設置すればよい。これら各横長状部材３，４，５の接続には、ここでは裏面に保持板（図示略）を設けてネジ止めで行っている。１４は各横長状板材３，４，５の接続部を示す。 Next, the horizontally long member 3 for the linearly curved portion 6 of the lower step portion, the horizontally long member 4 for the curved inclined portion 7 and the horizontally long member 5 for the linearly inclined portion 8 of the upper portion formed as described above. It is only necessary to connect to the longitudinal direction so that the short direction is vertical, and to install it on the stairs 2. In order to connect these horizontally long members 3, 4, and 5, here, a holding plate (not shown) is provided on the back surface and is screwed. Reference numeral 14 denotes a connecting portion of each horizontally long plate member 3, 4, 5.
上記のように形成したガイドレール１を階段に設置した場合、特に踊り場１０における湾曲傾斜状部７は、上記の如く「へ」の字状の横長状部材を湾曲形成したものであるから、図９の実線で示すように、上部段における階段上面２ｂから直線状傾斜部８下端面までの高さ（間隔）ｎは、下部段における階段上面２ａから直線状傾斜部６下端面までの高さ（間隔）ｍとほぼ等しくなっている。湾曲傾斜部７を形成した横長状部材４が、「へ」の字状でなくて仮に直線状のものを湾曲形成した場合には、同図で二点鎖線で示すように、踊り場１０で湾曲傾斜すると床面との傾斜角が大きくなって、上部段の直線状傾斜部６に接続されるから、両者の差は明らかである。 When the guide rail 1 formed as described above is installed on a staircase, the curved inclined portion 7 particularly in the landing 10 is formed by bending a horizontally long member in the shape of a letter “he” as described above. as shown by the solid line in 9, the linear slope portion 8 the lower end surface to the height (distance) n is the stairs top 2b, of the stairs top surface 2a of the lower stage until the linear slope portion 6 lower level height in the upper stage It is almost equal to (interval ) m. When the horizontally long member 4 that forms the curved inclined portion 7 is not shaped like a letter "H" but is linearly curved, it is curved at the landing 10 as shown by a two-dot chain line in FIG. When tilted, the tilt angle with the floor surface increases and is connected to the linear slope 6 in the upper stage, so the difference between them is clear.
このように、本発明のガイドレール１によれば、上段部での階段上面２ｂの高さｎが、下段部での階段団面２ａとの高さｍとほぼ等しい状態で連続しているから、無理なくスムーズな昇降移動が可能となり、椅子に座って該ガイドレール１上を昇降する高齢者その他の利用者は不安感を覚えなくなる。 Thus, according to the guide rail 1 of the present invention, the height n of the upper surface 2b of the staircase at the upper step is continuous in a state substantially equal to the height m of the staircase surface 2a at the lower step. Therefore, it is possible to move up and down smoothly without difficulty, and elderly people and other users who sit on a chair and move up and down on the guide rail 1 do not feel uneasy.
なお、このガイドレール１には、上記駆動用四角孔９に干渉しない位置に、長手方向への等間隔状に補強用横リブ１５を設けてあり、また短手方向への補強用縦リブ１６も設けてあり、上記補強用横リブ１５には階段への取付脚を設ければよい。上記実施例中で示した材質・寸法・角度等の数値や、ＣＡＤの機種名・ソフト等は例示であって、これに限定するものでないことは勿論である。 The guide rail 1 is provided with reinforcing horizontal ribs 15 at equal intervals in the longitudinal direction at positions not interfering with the driving square holes 9, and reinforcing vertical ribs 16 in the short direction. The reinforcing lateral rib 15 may be provided with a leg for attachment to the staircase. Of course, the numerical values such as the material, dimension, angle, etc., CAD model name, software, etc. shown in the above embodiments are merely examples, and the present invention is not limited thereto.
本発明は、椅子式階段昇降機用のガイドレールの製造方法であり、鉄製平板材から、各戸で異なる階段の形状に対応した直線傾斜状部６・水平湾曲状部・三次元形状の湾曲傾斜部等からなるガイドレールを、容易かつ安価で精度良く製造できると共に、階段への設置作業も容易・迅速かつ安価に行うことができ、しかも高齢者等の利用者に優しいものにすることができる。 The present invention is a method of manufacturing a guide rail for a chair type stair lift , and is made of an iron flat plate, a straight inclined portion 6 corresponding to different staircase shapes at each door, a horizontal curved portion, and a three-dimensional curved inclined portion. Can be manufactured easily, inexpensively and with high accuracy, and can be easily, quickly and inexpensively installed on the stairs, and can be made friendly to users such as elderly people.
