Description

【考案の詳細な説明】本考案はファスナーを回転させて２者を固定する装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for fixing two items together by rotating a fastener.

従来のファスナー装置を第１図〜第５図により説明する
。A conventional fastener device will be explained with reference to FIGS. 1 to 5.

１は装着物のキャビネットであり、その側面に開口２を
有しており、被装着物のカバー３が着脱自在に設けられ
ている。Reference numeral 1 denotes a cabinet for the mounted object, which has an opening 2 on its side surface, and a cover 3 for the mounted object is detachably provided.

カバー３の上端はその突部４をキャビネット１に保合さ
せ、下部はファスナー５をキャビネットの座６のファス
ナー穴６ａに挿入し、ファスナー５を回転させて固定す
る。The upper end of the cover 3 holds its protrusion 4 to the cabinet 1, and the lower part inserts a fastener 5 into a fastener hole 6a of a seat 6 of the cabinet, and then rotates and fixes the fastener 5.

このファスナー５０部分を以下詳細に説明する。This fastener 50 portion will be explained in detail below.

第２図の如くファスナー５は、先端から、軸に垂直な断
面形状が長円形状を有するストツバｍａ、該長円の寸法
ｔ（以下、長手す法ｔという）より小さい径ｄ’に
有する首部５ｂ、ストッパ一部５ａの長手寸法ｔより
大きい径を有する平板部５ｃｓおよびつ１み部５ｄから
構成されている。As shown in FIG. 2, the fastener 5 has a neck part having a diameter d' smaller than the dimension t of the ellipse (hereinafter referred to as lengthwise dimension t) from the tip end to a stop flange ma whose cross-sectional shape perpendicular to the axis is an ellipse shape. 5b, a flat plate portion 5cs having a diameter larger than the longitudinal dimension t of the stopper portion 5a, and a tab portion 5d.

かかるファスナー５はカバー３の穴３ａに強制的に嵌入
されている。The fastener 5 is forcibly fitted into the hole 3a of the cover 3.

穴３ａの径ｄは、ストッパ一部５ａの長手寸法ｔよ
り小さく、首部５ｂの径ｄより大きく設けられ、回転
自在であるが、ストッパ一部５ａと平板部５ｃで抜は止
めされている。The diameter d of the hole 3a is smaller than the longitudinal dimension t of the stopper portion 5a and larger than the diameter d of the neck portion 5b, and is rotatable, but is prevented from being pulled out by the stopper portion 5a and the flat plate portion 5c.

カバー３とファスナー５が樹脂で成形されていれば強制
的挿入は容易である。If the cover 3 and fastener 5 are made of resin, forced insertion is easy.

一方、キャビネット１０座６の穴６ａは、第５図に示す
如く、ストッパ一部５ａの断面形状と相似形状で、短手
方向の寸法ｔ”＋ストッパ一部５ａのｔより小さく設
けている。On the other hand, as shown in FIG. 5, the hole 6a in the cabinet 10 seat 6 has a similar cross-sectional shape to the stopper part 5a, and is smaller than the widthwise dimension t"+t of the stopper part 5a.

また、１＞１であり、またｔはストッパ一部５ａの短
手方向の長さよりも大きい。Further, 1 > 1, and t is larger than the length of the stopper portion 5a in the lateral direction.

穴６ａは長手方向（ｔの方向）が「取外し位置」の方
向になるように配置されている。The hole 6a is arranged so that its longitudinal direction (t 1 direction) is in the direction of the "removal position".

尚、穴６ａの短手方向（ｔ２の方向）が「固定位置」で
ある。Note that the lateral direction (t2 direction) of the hole 6a is the "fixed position".

かかる構成に釦いて、ファスナー５のストツノぐ一部５
ａの長手方向（ｔの方向）を「取外し位置」方向に向け
て座６の穴６ａに挿入し、つ１み部５ｄを９０度回転さ
せてストッパ一部５ａの短手方向を「固定位置」にすれ
ば、第２図に示す如く座６とカバー３はストッパ一部５
ａと平板部５Ｃの間にはさ１れ、カバー３をキャビネッ
ト１に固定できる。With this configuration, press the button 5 of the zipper 5.
Insert it into the hole 6a of the seat 6 with the longitudinal direction (direction of t) facing the "removal position", rotate the tab 1 5d 90 degrees, and move the short direction of the stopper part 5a to the "fixed position". ”, the seat 6 and the cover 3 will be attached to the stopper part 5 as shown in FIG.
The cover 3 can be fixed to the cabinet 1 by being sandwiched between the cover 1 and the flat plate part 5C.

両者を外す場合は逆の操作を行えばよい。If you want to remove both, just do the opposite operation.

しかしながら、この場合、ファスナー５０回転は３６０
度回転自在であるので、固定または取外しの位置（角度
）が定１らない欠点がある。However, in this case, 50 rotations of the fastener is 360
Since it is rotatable, there is a drawback that the position (angle) of fixing or removing is not fixed.

また、ファスナー５の首部５ｂの径ｄは座６の穴６ａ
の長手寸法ｔより小さいので、ｔ３とｄｌの差分だけ
、第５図において左右方向にがたつきを生ずるという欠
点があった。Also, the diameter d of the neck 5b of the fastener 5 is the hole 6a of the seat 6.
Since the longitudinal dimension t is smaller than the longitudinal dimension t, there is a drawback that the difference between t3 and dl causes wobbling in the left-right direction in FIG.

本考案はかかる欠点を改良するためになされたものであ
る。The present invention has been made to improve these drawbacks.

即ち、ストッパ一部に係合するようにカバーのキャビネ
ット側に突起を設けたものである。That is, a protrusion is provided on the cabinet side of the cover so as to engage with a portion of the stopper.

本考案を第６図〜第１０図に示す一実施例により説明す
る。The present invention will be explained with reference to an embodiment shown in FIGS. 6 to 10.

７はカバー３の穴３ａの周囲の２ケ所に設けられた突起
であり、座６を貫通するように突出している。Numerals 7 are protrusions provided at two locations around the hole 3a of the cover 3, and protrude so as to penetrate the seat 6.

突起７はストッパ一部５ａを穴６ｂに挿入する場合には
邪魔にならず、挿入したストッパ一部５ａを「取外し位
置」から「固定位置」に回転させるとストッパ一部５ａ
に当るように設けている。The protrusion 7 does not get in the way when the stopper part 5a is inserted into the hole 6b, and when the inserted stopper part 5a is rotated from the "removal position" to the "fixed position", the stopper part 5a is removed.
It is set up so that it corresponds to

突起７，７は穴３ａの中心として概略４５度の対角線上
に位置している。The protrusions 7, 7 are located approximately 45 degrees diagonally from the center of the hole 3a.

また、該２つの突起７−７の内距離ｔはストッパーｉ５
ａの長手方向ｔより小さく設けている。Moreover, the inner distance t between the two protrusions 7-7 is the stopper i5.
It is set smaller than the longitudinal direction t of a.

一方、座６の穴６ｂは、第１０図の如く突起７を挿入さ
せるために、その部分６ｅ’ｒ切欠いて大きく設けられ
ている。On the other hand, the hole 6b of the seat 6 is provided with a large cutout 6e'r in order to insert the projection 7 as shown in FIG.

長手方向の寸法ｔ３、短手方向の寸法ｔは従来と同様で
ある。The lengthwise dimension t3 and the widthwise dimension t are the same as in the conventional case.

かかる構成に釦いて、ファスナー５を「取外し位置」か
ら「固定位置」に回転させれば、ストッパ一部５ａが突
起７．７に当り、「固定位置」が定１す、固定を容易に
行えるものである。When this configuration is clicked and the fastener 5 is rotated from the "removal position" to the "fixed position", the stopper part 5a hits the protrusion 7.7, and the "fixed position" is fixed, making it easy to fix. It is something.

また、取外す場合に「取外し位置」を越えてさらに回転
させようとすると突起７，７に当るので、「取外し位置
」も定寸り、取外しも容易に行えるものである。In addition, if you try to rotate it beyond the "removal position" when removing it, you will hit the protrusions 7, 7, so the "removal position" is also fixed in size and can be easily removed.

また「固定位置」にトいて、ストッパ一部５ａが対角線
上に設けられた２つの突起７，７によりはさ１れるので
、前記左右方向のがたつきもなくなるものである。Further, in the "fixed position", the stopper part 5a is sandwiched between the two protrusions 7, 7 provided diagonally, so that the rattling in the left-right direction is also eliminated.

また、カバー３を樹脂材料で形成するならば、突起７は
容易に一体成形できるため、特別な部品の追加も必要と
しない効果がある。Moreover, if the cover 3 is made of a resin material, the protrusion 7 can be easily integrally molded, so there is an effect that no special parts are required.

以上の如く本考案によれば、ストッパ一部に係合するよ
うに被装着物に２つの突起を設けるという簡単な構造で
、容易にかつ確実な装着を行えるものである。As described above, according to the present invention, the attachment can be easily and reliably carried out with a simple structure in which two protrusions are provided on the object to be attached so as to engage with a portion of the stopper.
