Description
本発明は、装置の操作レバーに、挿入穴が形成されたノブを取り付けるノブの取付構造に関する。 The present invention relates to a knob mounting structure for mounting a knob having an insertion hole formed on an operation lever of an apparatus.
図6に示すように、装置の操作レバー1は平板状で、その一方の面上には先端側に向かって高さが低くなる突起3が形成されている。一方、樹脂等の弾性材でなるノブ5には、操作レバー1が挿入される挿入穴7が形成されている。そして、挿入穴7の壁面には、挿入された操作レバー1の突起3が係合する係合穴9が形成されている(例えば、特許文献1)。
As shown in FIG. 6, the operation lever 1 of the apparatus has a flat plate shape, and a protrusion 3 whose height decreases toward the distal end is formed on one surface thereof. On the other hand, an
しかし、図6に示す構成では、操作レバー1をノブ5の挿入穴7に挿入し、操作レバー1の突起3がノブ5の係合穴9に係合すると、ノブ5を取り外すことが難しい問題点がある。そこで、図7、図8に示すような構成のノブの取付構造が提案されている。図7は分解斜視図、図8は図7において操作レバーにノブが取り付けられた状態での切断線A−Aでの断面図である。
However, in the configuration shown in FIG. 6, it is difficult to remove the knob 5 when the operating lever 1 is inserted into the
図において、装置の操作レバー11は平板状で、その一方の面上には、切り起こし加工により、先端側に向かって高さが低くなる突起13が形成されている。一方、樹脂等の弾性材でなるノブ15には、操作レバー11が挿入される挿入穴17が形成されている。そして、挿入穴17の開口上部には操作レバー11の挿入方向(図7で矢印B方向)と反対方向に伸び、可撓性を有するツメ部19が形成されている。ツメ部19には、挿入された操作レバー11の突起13が係合する係合穴21が形成されている。 In the figure, the operation lever 11 of the apparatus is in the shape of a flat plate, and a projection 13 whose height decreases toward the tip side is formed on one surface thereof by cutting and raising. On the other hand, an insertion hole 17 into which the operation lever 11 is inserted is formed in the knob 15 made of an elastic material such as resin. A flexible claw portion 19 is formed in the opening upper portion of the insertion hole 17 so as to extend in a direction opposite to the insertion direction of the operation lever 11 (the arrow B direction in FIG. 7). The claw portion 19 is formed with an engagement hole 21 with which the projection 13 of the inserted operation lever 11 is engaged.
このような構成によれば、ツメ部19を図8において矢印H方向に撓ませることによりツメ部19の係合穴21と操作レバー11の突起13との係合が解除でき、ノブ15を容易に取り外すことができる。
しかし、図7、図8に示す構成のノブの取付構造においては、以下のような問題点がある。
(1)車両のシートのシートスライド装置の操作レバーにこのようなノブの取付構造を用いた場合、操作レバー、ノブはシートのシートクッションの側部に設けられる。特に、RV車等の背の高い車両の場合、乗員が車両内に乗り込む際に、ノブに手をついたり、乗員の臀部がノブに当たる場合がある。
However, the knob mounting structure shown in FIGS. 7 and 8 has the following problems.
(1) When such a knob mounting structure is used for an operation lever of a seat slide device for a vehicle seat, the operation lever and the knob are provided on the side portion of the seat cushion of the seat. In particular, in the case of a tall vehicle such as an RV vehicle, when the occupant gets into the vehicle, the knob may be touched or the buttock of the occupant may hit the knob.
即ち、図9に示すように、ノブ15の先端に矢印F方向の大きな荷重が作用すると、ツメ部19が塑性変形する。このツメ部19の塑性変形の方向は、ツメ部19の係合穴21と操作レバー11の突起13との係合が解除される方向(図8における矢印H方向)であり、ノブ15が操作レバー11より脱落する問題点がある。
(2)図9に示すように、ノブ15の先端に矢印F方向の大きな荷重が作用し、ツメ部19が塑性変形すると、ツメ部19周辺の脆弱部(図7のC部分)に割れを生じ、ノブ15のツメ部19の係合穴21と、操作レバー11の突起13との係合が解除され、ノブ15が操作レバー11より脱落する問題点がある。
That is, as shown in FIG. 9, when a large load in the direction of arrow F acts on the tip of the knob 15, the claw portion 19 is plastically deformed. The direction of the plastic deformation of the claw portion 19 is a direction in which the engagement between the engagement hole 21 of the claw portion 19 and the protrusion 13 of the operation lever 11 is released (the direction indicated by the arrow H in FIG. 8). There is a problem of dropping from the lever 11.
(2) As shown in FIG. 9, when a large load in the direction of arrow F acts on the tip of the knob 15 and the claw portion 19 is plastically deformed, the fragile portion (C portion in FIG. 7) around the claw portion 19 is cracked. This causes a problem that the engagement between the engagement hole 21 of the claw portion 19 of the knob 15 and the projection 13 of the operation lever 11 is released, and the knob 15 falls off the operation lever 11.
本発明は上記問題点に鑑みてなされたもので、その課題は、大きな荷重が作用してもノブが脱落しないノブの取付構造を提供することにある。 The present invention has been made in view of the above problems, and an object thereof is to provide a knob mounting structure in which the knob does not fall off even when a large load is applied.
