【考案の詳細な説明】
本考案は、１スラット外面を外側にして巻取る内巻き、
ならびにスラット外面を内側に巻く外巻の何れをも可能
にし、２巻取ドラムへの巻取時に発生するスラット同志
によるすれ傷を完全に防止し、３巻取時に合理的な収納
が可能なスラットを以て組まれたアルミシャッタースラ
ットに関するものである。[Detailed description of the invention] This invention is an inward winding method in which one slat is wound with the outer surface facing outward.
The slat also enables both external winding, in which the outer surface of the slat is wound inward, completely prevents scratches caused by the slats that occur when winding onto the second winding drum, and allows for rational storage when winding the third winding. This relates to aluminum shutter slats assembled with.
従来第１図の如きアルミ押出型のシャッタースラットは
知られている。An aluminum extrusion type shutter slat as shown in FIG. 1 is conventionally known.
１はスラットの本体部でその上縁に断面Ｃ−型の雌型イ
ンターロック部２、下縁に球状の雄型インターロック部
３が一体に設けられている。Reference numeral 1 denotes a main body portion of the slat, and a female interlock portion 2 having a C-shaped cross section is integrally provided on its upper edge, and a spherical male interlock portion 3 is provided on its lower edge.
そして、雌型インターロック部２に雄型インターロック
部３を回転自在に嵌めて結合してシャッターを構成して
いる。The male interlock part 3 is rotatably fitted and coupled to the female interlock part 2 to form a shutter.
この構造では雄型と雌型のインターロック部２，３の形
状からして、内側に約６０°程度の折曲回転ができ、外
側には全く折曲できない。In this structure, due to the shapes of the male and female interlocking parts 2 and 3, it is possible to bend inward by about 60 degrees, but it cannot be bent outward at all.
即ち内巻、外巻にも巻取れる正、逆円用のスラットでは
なかった。In other words, it was not a slat for normal or reverse circles that could be wound inward or outward.
本考案はこのような公知シャッタースラットの問題を解
決しようとしたものである。The present invention is an attempt to solve the problems of such known shutter slats.
第２図は本考案に係るシャッタースラットをインターロ
ックして結合１−たシャッターである。FIG. 2 shows a shutter in which shutter slats are interlocked and combined according to the present invention.
図で明らかな如く、そのインターロック結合部の断面形
状は公知のものに比し相当に異っている。As is clear from the figure, the cross-sectional shape of the interlocking joint is considerably different from that of the known one.
第３図と第４図を参照してその下部インターロック部４
と上部インターロック部５について説明する。With reference to FIGS. 3 and 4, the lower interlock portion 4
The upper interlock portion 5 will be explained.
下部インターロック部４は断面円形の軸部４ａを先端に
有限鉤形をなしている。The lower interlock portion 4 has a finite hook shape with a shaft portion 4a having a circular cross section at its tip.
６は下部インターロック部４の上方に一体的に設けられ
たＬ型内向突起である。Reference numeral 6 denotes an L-shaped inward protrusion that is integrally provided above the lower interlock portion 4 .
上部インターロック部５の前記軸部４ａと接触する部分
が山形部５ａをなしている。The portion of the upper interlock portion 5 that contacts the shaft portion 4a forms a chevron portion 5a.
図の例では片側が６００、他の側が４５°で計１０５°
程度開いている。In the example shown, one side is 600 degrees and the other side is 45 degrees, for a total of 105 degrees.
It's somewhat open.
山形部以外は第４図の如くたとえば数種類の円弧の連続
曲線を以て構成されている。As shown in FIG. 4, the parts other than the chevron-shaped portion are constructed of, for example, continuous curves of several types of circular arcs.
以上の構成であるから、第２図の如く上・下のスラット
がインターロックされたとき、軸部４ａと山形部５ａと
は２点で線接触をなしている。With the above configuration, when the upper and lower slats are interlocked as shown in FIG. 2, the shaft portion 4a and the chevron portion 5a are in line contact at two points.
この保合状態で第５図の如く上方のスラットが巻取軸（
又は巻取ホイール）に巻かれるとき、接触面が少いので
音の発生が小さくなる。In this secured state, the upper slat is attached to the winding shaft (as shown in Figure 5).
When wound on a winding wheel (or a winding wheel), there is less contact surface, so less noise is generated.
この場合、上方のスラットの山形部５ａの角度を出来る
丈鋭角にすることにより、下側スラットの軸部４ａが常
に２本の線接触（第５図の如き断面でいえば２点での点
接触）の回転をすることになるので、発生音は非常に小
さくなり、静かなシャッターとなり得る。In this case, by making the angle of the chevron portion 5a of the upper slat as acute as possible, the shaft portion 4a of the lower slat is always in two line contact (in the cross section as shown in Fig. 5, two points). Since the shutter rotates (contact), the noise generated is very small, making it a quiet shutter.
以上のごとく、本考案はインターロック部の形状を軸部
４ａと山形部５ａの係合にしたので、面接触を極力減ら
すことができ、円滑な回転が可能となった。As described above, in the present invention, the shape of the interlock portion is such that the shaft portion 4a and the chevron portion 5a engage with each other, so that surface contact can be reduced as much as possible, and smooth rotation is possible.
又り型内向突起６を下部インターロック部の軸部４ａの
上方に一体に設けたので第６図に示す如くドラム８への
巻取時インターロック部をドラムから浮上らせることが
でき、父型なって巻かれる際スラット同志の表裏面の接
触面が減り、スラットの傷付きが少くなる。Since the inward protrusion 6 is integrally provided above the shaft portion 4a of the lower interlock portion, the interlock portion can be lifted up from the drum when winding onto the drum 8 as shown in FIG. When the slats are rolled into a shape, the contact surfaces between the front and back surfaces of the slats are reduced, and the slats are less likely to be damaged.
