Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to an airtight maintenance device that allows stable running of shoji in satsushi windows. Airtightness that allows stable running of shoji shoji applied to fittings such as aluminum sash windows and doors in various types such as double sliding, single sliding, and horizontal sliding when attached to buildings that may be exposed to strong winds. This invention relates to an improvement of a holding device.

[Conventional technology]

In general, this type of aluminum sash window or door, for example, a sliding sash window, is made up of a window frame consisting of upper and lower horizontal frames and left and right vertical frames. It consists of a set of shoji consisting of each horizontal stile and each vertical stile on the left and right sides, and is installed so that it can be slid open and closed in the left and right directions.In order to obtain a smooth opening and closing action, it is necessary to The normal form is that the corresponding part of the shoji upper stile is fitted into the upper rail part, and a pair of door wheels placed on the shoji lower stile are rollably supported on the lower rail member of the window lower frame. It is.

In a sliding sash window configured in this manner, conventionally, in order to stably slide and run each set of shojis, it was necessary to move only the upper part of the sash window, either the upper frame or the upper stile. By interposing a so-called anti-slip member made of nylon pieces or the like on the contact part of one side with the other, this anti-slip member prevents the shoji from rattling inward and outward. This ensures stable and smooth running, and at the bottom of the sash window, the door wheel of the lower stile is attached to the lower rail member of the lower frame, allowing for smooth sliding. Due to the prerequisites, the current situation is that no such anti-slip members are interposed.

On the one hand, in the case of a sliding sash window with this configuration, it is necessary to operate each set of shoji in a stable manner while avoiding interference between them as described above, but on the other hand, on the other hand, Contrary to these conditions, it is necessary to keep each shoji in close contact with the window frame in an airtight and watertight manner in the closed state, so when each shoji is pulled together in this closed state, Generally, a so-called tight member such as an airtight material or a watertight material is provided at the mutually abutting portion.

[Problem that the invention attempts to solve]

However, with regard to the stable running of each set of shoji installed in the window frame mentioned above and the ability to maintain airtightness when closed, buildings themselves tend to become taller. Currently, it is known that even if there is almost no wind on relatively low floors, the shoji parts of windows on relatively high floors can receive quite strong winds due to air currents. In this case, due to the wind pressure that the shoji receives,
The lower stile portion of the shoji or the lower frame of the window that is not provided with anti-slip members is constantly in contact with the tight member provided as an airtight material or watertight material, and as a result, the mutual frictional resistance increases, causing the shoji to deteriorate. There are disadvantages in that stable and smooth running cannot be obtained, and the tight member itself deteriorates early and becomes unusable.

Therefore, as a means to eliminate such drawbacks, the applicant first proposed the
The technique described in the publication No. 1 (hereinafter referred to as the first conventional example) was proposed.

In short, in this first conventional example, the elements that guide each shoji, in this case, the upper and lower rail members of the window frame, are placed in the door closing position, and each shoji is placed in its entirety on the corresponding part of the window frame. In order to guide the door roller provided at the bottom of each shoji in accordance with the pushed-out protrusion of the lower rail member, the protrusion is pushed out to allow the door roller to approach the lower rail member. This lip is made smaller in diameter.

Therefore, in the configuration of the first conventional example, as each shoji is opened and closed, each shoji can be brought into close contact with the window frame at each door closing position. Because the padskin is placed as a stopper on the bottom side of the shoji,
It is possible to achieve both the stable running of the shoji mentioned above and the maintenance of airtightness in the closed state.

However, in the case of this configuration, in terms of structure, a new protrusion must be formed on the aluminum profile that has been extruded into a predetermined cross-sectional shape, and the door wheel as one reference member must be shaped. However, in addition to the need to re-shape it to a smaller-diameter lip, it is also necessary to add a seal to prevent rubbing.In other words, if standardized off-the-shelf parts are used as they are, However, in terms of operation, each shoji is drawn in the direction of close contact according to the shape of the protruding part of the rail member. The corresponding surface of each shoji is always in sliding contact with the sealing pad only during the running period until it is completely in contact, causing the sealing padding to wear each time, reducing its useful life. There are disadvantages such as becoming

Separately, as a prior art, a proposal described in Japanese Utility Model Application Publication No. 54-3845 (hereinafter referred to as the second conventional example) has also been made.

In other words, in the second conventional example, when the upper rail member of the window frame is in the door closing position, the entire shoji is moved closer to the packing located on the corresponding part of the window frame. A cut-out part and a sloped part are formed, and a locking member is provided at the top of each shoji and receives a kind of cam action by sliding with the slope part, and as a result, is fitted into the cut-out part. A slip stopper with a mating protrusion is attached, and in this embodiment, the mounting position is on the upper side of the window frame and each shoji, so the above-mentioned disadvantages on the lower side are eliminated. Moreover, it was difficult to avoid disadvantages similar to those of the first conventional example described above.

In addition, in the case of the configuration of the second conventional example described above, for example, the configuration of the cutout, slope, and contact stopper provided on the upper side of the window frame and each shoji may be left as is. In this case, even if a cutout and an inclined part are formed in the lower rail member of the window frame, and a sway stopper with an engaging convex part is attached to the top of each shoji, in this case, However, due to the presence of the cutout formed in the lower rail member, each shoji cannot necessarily run smoothly on the lower rail member.

This idea was made to solve these conventional problems, and its purpose is to adopt the structure of the conventional satsushi window as much as possible, and to improve the existing standardization. This type of product uses manufactured parts, a small number of parts, and a small amount of processing to achieve the desired effect, that is, the stable running of each shoji and the airtightness of the window frame in the closed state. An object of the present invention is to provide an airtight maintenance device that enables stable running of a shoji in a sash window.

[Means for solving problems]

In order to achieve the above-mentioned object, an airtight maintenance device according to the present invention that allows the shoji of a sash window to run stably is provided with a door roller supported on a window frame and a lower rail member protruding from the lower frame of the window frame. The sash window has a sash window that can be opened and closed while traveling, and a sash window is provided with a tight member on at least one of the window frame and the shoji, which holds the two in close contact when the closed shoji is drawn. A contact body with a contact part protruding inside the lower part of the shoji is fixed, and a web part at the lower part of the rail surface of the lower rail member corresponds to the contact part of the shoji when it is completely closed. An engagement hole is formed at the position where the contact portion is received.

[Effect]

That is, in the airtight maintenance device of this invention,
When the shoji is open, the contact part of the contact body provided on the shoji slides against the web part of the lower rail member of the window frame, and the shoji can be easily and extremely stably moved on the rail surface. It is possible to operate the sliding shoji, and when the shoji is completely closed, the contact part of the contact body corresponds to the engagement hole of the lower rail member,
By pulling the shoji closer together, the abutting portions are fitted into the engagement holes, allowing the window frame and the shoji to be held in close contact with each other with the interposition of the tight member.

〔Example〕

Hereinafter, an example of an airtight maintenance device that allows stable running of shoji in a sash window according to this invention will be described.
This will be explained in detail with reference to each of FIGS. 1 to 10.

Fig. 1 is a vertical sectional view showing the configuration of a sash window to which this embodiment is applied, Fig. 2 is a perspective view showing the same abutment body taken out, and Fig. 3 is a lower frame rail and its engagement. FIG. 3 is an explanatory plan view showing the positional relationship between holes and abutting bodies.

First, in FIG. 1, reference numeral 1 indicates the window frame of a sliding sash window, and as is well known, it consists of an upper frame 2, a lower frame 3, and both left and right vertical frames (not shown). 4 is an inner shoji, 5 is an outer shoji, and 10 is a so-called tight member such as an airtight material or a watertight material.

Further, in FIG. 2, reference numeral 6 denotes a contact body made of a hard synthetic resin material such as nylon or a light metal material, and having a main body part 6a with a "shaped" longitudinal cross section, and a flat trapezoidal contact member with a short tip surface on the lower inner side surface. In addition to forming the contact portion 6b, a mounting hole 6 is formed in the mounting portion 6c on the upper side.
d is perforated.

This abutting body 6 is attached to the lower surfaces 4b and 5b of the lower stile 4a and 5a of the inner and outer shoji 4 and 5 described above, or to the width direction of the shoji on the corresponding surface at the bottom of each vertical stile. There are 7 door cars in each.
By fixing the mounting holes 6d with screws or the like at multiple positions that do not hinder the rolling of the shoji, the tip surface of the abutting portion 6b can be attached to each of the inner and outer shoji 4, 5.
The outdoor side surfaces 8a, 8 of each of the lower rail members 8, 8, which are provided protrudingly on the lower frame 3 for travel guidance.
Each is in sliding contact with part a.

Here, in addition to the configuration shown in FIG. 2, the abutting body 6 can be formed into various shapes as shown in FIGS. 9A to 9E. That is, Figure A shows a shape in which the entire abutting part 6b protrudes in an arc shape, and Figure B shows a shape in which the abutting part 6b is similarly projected in an arc shape, and mounting edges are formed on both sides. Figure C shows a shape with a substantially cylindrical abutting part 6b protruding from the middle part, and Figure D shows a trapezoidal abutting part 6b protruding from the middle part, and a shape with a trapezoidal abutting part 6b protruding from the middle part. The shape in which mounting edges are formed, as shown in FIG. It can be used in each case in the same manner as in the previous example.

In addition, in FIG. 3, each web portion 8a of each lower rail member 8, 8 protrudingly provided on the lower frame 3, excluding each rail surface that rolls and guides each door roller 7, 7. , 8a, the necessary parts in the longitudinal direction, here, the inner and outer shoji 4,
5 is fully closed, each contact body 6, 6
Engagement holes 9, 9 capable of receiving the respective abutting portions 6b, 6b of these abutting bodies 6, 6 are formed at required locations corresponding to the fixed positions of In order to firmly and easily receive the shoji, there is a shoji on the side that can be completely pulled toward the window frame 1 side with the inner and outer shoji 4 and 5 fully closed, as will be described later. In order to facilitate sealing, guide portions 9a, 9a are respectively projected so as to be gradually inclined inward.

In addition to the configuration shown in FIG. 2, the engaging holes 9, 9 can be formed in various shapes as shown in FIGS. 9A and 9B. That is, Figure A shows the engagement holes 9, 9 simply opened in a rectangular shape from the front without forming the guide parts 9a, 9a, and Figure B shows the engagement holes formed slightly larger. A guide block 80 having portions corresponding to the guide portions 9a, 9a is fixed in the matching holes 9, 9, and can be used in each of these cases in the same manner as in the previous example.

Next, FIGS. 4 to 8 show the engagement hole 9 of the lower rail member 8 and the tight member 10 in the window frame 1.
and state changes of the shoji 4 with the abutting body 6 when the shoji 4 moves (when opened) and when it is pulled together (when closed) are shown.

That is, among these figures, FIGS. 4 and 5 are a plan view and a partial cross-sectional view showing the positional relationship when the shoji is running, and show the contact body fixed to the lower surface part 4b of the lower stile 4a. 6 is the lower rail member 8
In this state, there is a minute gap of about 1 to 1.5 mm between the indoor side surface 4c of the shoji 4 and the tight member 10 of the lower frame 3. Therefore, the shoji 4 can run smoothly on the lower rail member 8 by the door roller 7 regardless of the presence of the engagement hole 9.

FIG. 6 is a plan view showing the positional relationship just before the shoji is pulled in, and the abutting body 6 fixed to the lower surface part 4b of the lower stile 4a is connected to the lower rail member 8.
It slides while being in contact with the outdoor side surfaces 8a, and is moved to the engagement hole 9 position.

Furthermore, FIGS. 7 and 8 are a plan view and a partial sectional view showing the positional relationship when the shoji is pulled together, and when a pulling action is applied to the shoji 4, the contact portion of the contact body 6 6b is the inclined surface 6 on both sides thereof.
The interior side surface 4c of the shoji 4, including a part of the shoji 4, is fitted and engaged into the engagement hole 9 until it is brought into close contact with the tight member 10 of the lower frame 3 with a required pressure.

Note that the form of close contact between the indoor side surface 4c of the shoji 4 and the tight member 10 of the lower frame 3 shown in the above embodiments does not necessarily have to be as shown in the drawings; For example, various forms can be adopted, such as being attached to the lower stile 4a, 5a side.In short, by pulling each closed shoji, the lower stile and the tight member, and the tight member and the lower frame can be attached. , and the tight members may be brought into close contact with each other by contact pressure.

[Effect of idea]

As detailed above, when using this idea,
It has a window frame and a shoji which is supported by a door roller and can be run and opened and closed on a lower rail member protruding from the lower frame of the window frame, and at least one of the window frame and the shoji has a In a sash window equipped with a tight member that holds the cut shoji in close contact when the two are pulled together, a contact body with a protruding abutment part is fixed in the lower part of the shoji, and a lower rail member is used to fix the contact body. An engagement hole is formed in the web part at the bottom of the rail surface at a position that corresponds to the contact part of the shoji when it is closed, so that when the shoji is open, the window frame will not fit. While the contact part of the contact body provided on the shoji is in sliding contact with the web part of the lower rail member,
This shoji can be easily and extremely stably operated on a rail surface, here a smooth rail surface with no missing parts, without any influence from the engagement holes. Furthermore, in the fully closed position of the shoji, the abutting part of the contact body corresponds to the engaging hole of the lower rail member, so by pulling the shoji closer, the abutting part fits into the engaging hole. When engaged, the window frame and the shoji can be brought into close contact with each other with the interposition of the tight member, and can be held well in an airtight and watertight manner, and structurally, it is better than each of the conventional examples described above. Unlike the above, it is only necessary to form an engagement hole at a predetermined position in the web part of the lower rail member and to fix a relatively simple shaped abutting body within the lower part of the shoji. In addition, standardized off-the-shelf parts can be used as they are with a little processing, and the number of parts can be reduced.In addition, when the abutment part is inserted into the engagement hole, a tight member is required for tight contact. Since no rubbing action is applied to the material, there is no abrasion and the service life can be significantly improved, which has various practical effects.
