Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は、弾性バンドを簡単に、而かもしつか
りと止着することが出来るやすの弾性バンド止着
装置に係るものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elastic band fastening device for a chair that can easily and conveniently fasten an elastic band.

[Conventional technology]

実公昭56−1151号公報で示すやすの弾性バンド
止着装置は、柄１に切込溝３を形成したり、弾性
バンド４端部に係止膨出部５を形成したりしなけ
ればならないから加工が大変であり、それだけ量
産を妨げ、製品をコストアツプさせる欠点があつ
た。 The elastic band fastening device for the Yasu shown in Japanese Utility Model Publication No. 1151/1980 requires a cut groove 3 to be formed in the handle 1 and a locking bulge 5 to be formed at the end of the elastic band 4. It is difficult to process, which hinders mass production and increases the cost of the product.

[Problem that the invention attempts to solve]

本考案は、かかる欠点を解決したもので、弾性
バンドを簡単にして、而かも確実に止着すること
が出来るやすの弾性バンド止着装置に係るもので
ある。 The present invention solves these drawbacks and relates to an elastic band fastening device that can simplify and securely fasten an elastic band.

[Means for solving problems]

パイプ製の柄杆１０の先端部に突刺杆１１を設
けたやすにおいて、無端弾性バンド１２の一部内
側に嵌入体１３を一体に突設し、この嵌入体１３
を柄杆１０後端部１０ａ内に圧嵌入し、この柄杆
１０後端部１０ａの外側から抜け止めピン１４を
打ち込み止着して柄杆１０後端部１０ａに無端弾
性バンド１２を止着する。 In a case in which a piercing rod 11 is provided at the tip of a handle rod 10 made of pipe, a fitting body 13 is integrally provided inside a part of the endless elastic band 12, and this fitting body 13 is provided.
is press-fitted into the rear end 10a of the handle rod 10, and a retaining pin 14 is driven from the outside of the rear end 10a of the handle rod 10 to secure it, thereby securing the endless elastic band 12 to the rear end 10a of the handle rod 10. do.

〔Example〕

図面の柄杆１０は２本継ぎを図示している。 The handle rod 10 in the drawings shows a two-piece joint.

図面の無端弾性バンド１２はゴムバンドを使用
している。 The endless elastic band 12 in the drawing uses a rubber band.

図面の嵌入体１３はピン孔１５をあらかじめ穿
孔している。 The insert body 13 in the drawing has a pin hole 15 drilled in advance.

図中１６は柄杆１０側にピン孔である。 In the figure, 16 is a pin hole on the handle rod 10 side.

[Effect of idea]

本考案は、上述の様に構成したから次の様な特
長を有するものである。 Since the present invention is configured as described above, it has the following features.

１無端弾性バンド１２に嵌入体１３を一体に設
け、この嵌入体１３を柄杆１０後端部１０ａ内
に圧嵌入し、その外側から抜け止めピン１４を
打ち込んで止着するものであるから実公昭56−
1151号公報で示す止着方法に比して極めて簡単
であり、それだけ製作も容易となり、量産し、
製品を安価に提供することになる。1. A fitting body 13 is integrally provided with the endless elastic band 12, and the fitting body 13 is press-fitted into the rear end portion 10a of the handle rod 10, and the retaining pin 14 is driven in from the outside to secure it. Kosho 56-
It is extremely simple compared to the fastening method shown in Publication No. 1151, and it is easier to manufacture and can be mass-produced.
Products will be provided at low prices.

２この嵌入体１３は柄杆１０後端部１０ａ内に
圧嵌入した上、外側から抜け止めピン１４を打
ち込んで止着しているから抜け止めピン１４が
抜けたり、折れたりしない限り無端弾性バンド
１２を外れることがなく、しつかりと止着さ
れ、安心して使用することが出来る。2 This fitting body 13 is press-fitted into the rear end portion 10a of the handle rod 10, and is fixed by driving the retaining pin 14 from the outside, so as long as the retaining pin 14 does not come out or break, the endless elastic band will continue. 12 will not come off and will be firmly attached, allowing you to use it with confidence.

３また無端弾性バンド１２で柄杆１０後端部１
０ａの両側を被覆するから従来品のようなキヤ
ツプが不要となり、一層製品のコストダウンを
計ることが出来る。3 In addition, the rear end portion 1 of the handle rod 10 is attached with an endless elastic band 12.
Since both sides of 0a are covered, there is no need for a cap like in conventional products, and the cost of the product can be further reduced.

４この嵌入体１３も無端弾性バンド１２を成型
する時に一体に成型すれば良いから量産を妨げ
ることがない。4. This fitting body 13 can also be integrally molded when molding the endless elastic band 12, so mass production is not hindered.
