Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案はツマミ軸の摺動部を軸受にて保持したツマミ
取付装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a knob mounting device in which a sliding portion of a knob shaft is held by a bearing.
従来の装置は、実開昭61-42742に記載のように、ツマ
ミ外周を筐体のツマミ穴に複数個の凸部を設けて、位置
決めしており寸法精度がでにくく、ツマミにガタ、傾き
が発生する。又、潤滑性プラスチック樹脂の筐体は塗
装、印刷、接着等が困難であり、材料もコスト高で使用
できず、ツマミ摺動部に粉ふきの発生の原因となってい
た。As described in Japanese Utility Model Laid-Open No. 61-42742, the conventional device is provided with a plurality of convex portions on the outer circumference of the knob in the knob hole of the housing for positioning, and it is difficult to achieve dimensional accuracy. Occurs. Further, the housing made of a lubricious plastic resin is difficult to paint, print, bond, etc., and the material cannot be used due to the high cost, which causes dusting on the sliding portion of the knob.
従来技術は、電源スイッチ等のON,OFF動作をさせるツ
マミにガタや傾き、及び摺動部の粉吹き、引っかかりに
ついて配慮がされておらず、摺動部にグリス等を塗布し
ており、作業性が悪く又、グリスが表面に出て外観を損
ねていた。The conventional technology does not consider backlash and inclination of the knobs for turning on and off the power switch, etc., and dusting and catching of sliding parts, and grease is applied to the sliding parts. Poor performance, and grease was exposed on the surface, impairing the appearance.
本考案の目的は、ツマミ摺動部に潤滑性プラスチック
樹脂の軸受を使用しツマミを保持することで、安価で簡
単にツマミを良好に動作させることにある。It is an object of the present invention to use a bearing made of a lubricious plastic resin for a sliding portion of the knob and hold the knob so that the knob can be operated easily at low cost and easily.
上記目的を達成するために、ツマミ摺動部のツマミ軸
に設けた十字リブと極小の隙間をもったツマミ軸受を使
用してツマミを保持したものである。In order to achieve the above object, a knob is held by using a cross rib provided on a knob shaft of a knob sliding portion and a knob bearing having a very small gap.
又、ツマミ軸受は摺動時の摩耗による粉吹きや引っか
かりの防止するために、潤滑性プラスチック樹脂で成形
したものである。Further, the knob bearing is formed of a lubricious plastic resin in order to prevent powder blow and catch due to abrasion during sliding.
ツマミに一体成形されたツマミ軸と、それに設けられ
た十字リブが、ツマミ軸受の十字穴に挿入され、ツマミ
軸が摺動する。ツマミ軸の十字リブと十字穴の隙間を極
小にし、軸受に潤滑性プラスチック樹脂を使用すること
によって、ツマミにガタや傾き及び摺動時の摩耗による
粉吹きや、引っかかり等の動作不良が生じることがな
い。The knob shaft integrally formed with the knob and the cross rib provided on the knob shaft are inserted into the cross holes of the knob bearing, and the knob shaft slides. Minimizing the clearance between the cross rib and the cross hole of the knob shaft and using a lubricative plastic resin for the bearing may cause the knob to loosen or powder blows due to tilt or abrasion during sliding, or to cause malfunctions such as catching. There is no.
本考案の実施例を以下図面と共に説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第３図、第４図に示すようにツマミ３は、一体成形さ
れたツマミ軸６と十字リブ6aからなっており、このツマ
ミ軸６がツマミ軸受５の十字穴5bに挿入されツマミ３が
保持されている。ツマミ軸受５は、軸受に成形された嵌

ミ３と軸受５の間に、軸受に設けられたスプリングガイ
ドリブ5dにより位置決めされたスプリング２が入ってお
り、ツマミ３が前後に摺動するようになっている。As shown in FIGS. 3 and 4, the knob 3 is composed of a knob shaft 6 and a cross rib 6a which are integrally formed. The knob shaft 6 is inserted into the cross hole 5b of the knob bearing 5 and the knob 3 is held. Has been done. The knob bearing 5 is fixed to the front frame 1 by the elastic force of the fitting claws 5c formed on the bearing. A spring 2 positioned by a spring guide rib 5d provided on the bearing is inserted between the knob 3 and the bearing 5 so that the knob 3 slides back and forth.
第１図、第２図は、本実施例の組立てた状態を示して
おり、ツマミ３を押すと、ツマミ軸６でスイッチシャフ
ト４が押され、基板８に取付けられた電源スイッチ７が
ONとなる。又、ツマミ３を押さない時は、ツマミスプリ
ング２の力によってツマミがもとの位置に戻る。さらに
再度ツマミ３を押すとスイッチシャフト４が押され、ON
からOFFとなる。この様にツマミ３を押すことにより、
電源スイッチ７をON,OFFさせている。FIG. 1 and FIG. 2 show the assembled state of the present embodiment. When the knob 3 is pushed, the switch shaft 4 is pushed by the knob shaft 6 and the power switch 7 attached to the board 8 is pushed.
Turns on. When the knob 3 is not pushed, the knob spring 2 returns the knob to its original position. When the knob 3 is pushed again, the switch shaft 4 is pushed and turned on.
To OFF. By pushing the knob 3 in this way,
The power switch 7 is turned on and off.
この為、ツマミ３は電源スイッチ７のON,OFFごとに、
前後に動作しており、ツマミ軸６とツマミ軸受５の十字
穴5bは常に摺動している。Therefore, the knob 3 is turned on and off each time the power switch 7 is turned on and off.
It operates back and forth, and the knob shaft 6 and the cross hole 5b of the knob bearing 5 always slide.
したがってツマミ３を保持しているツマミ軸の十字リ
ブ6aと、ツマミ軸受の十字穴5bの隙間を極小にし、ツマ
ミ軸受５に潤滑性プラスチック樹脂を使用することによ
り、ツマミ３のガタ、傾き及び摺動時の摩耗による粉吹
きや引っかかりがなくなり、ツマミ３の摺動が良好に動
作する。Therefore, the clearance between the cross rib 6a of the knob shaft holding the knob 3 and the cross hole 5b of the knob bearing is minimized and the knob bearing 5 is made of a lubricious plastic resin so that the rattling, inclination and sliding of the knob 3 can be prevented. The powder blow and the catching due to the abrasion during the movement are eliminated, and the sliding of the knob 3 works well.
以上説明したように潤滑性プラスチック樹脂を材料に
したツマミ軸受を使用することにより、粉吹きや引っか
かりを防止することができ、ツマミの動作を常に良好に
行なわせることができる。又、ツマミ軸の十字リブと軸

タ、傾きも防止することができる。As described above, by using the knob bearing made of a lubricious plastic resin, it is possible to prevent dust blowing and catching, and it is possible to always operate the knob satisfactorily. Further, by minimizing the gap between the cross rib of the knob shaft and the cross hole of the bearing, it is possible to prevent rattling and tilting of the knob.
