〔産業上の利用分野〕
本発明は、一次元方向又は二次元方向に連続し且つ切り
側に弾性付勢された接点を有するスイッチ部材を用いて
、他物の接触を検出する接触式スイッチに関する。Detailed Description of the Invention [Industrial Field of Application] The present invention uses a switch member having a contact that is continuous in one or two dimensions and is elastically biased on the cutting side to prevent contact with another object. This invention relates to a contact switch that detects.
かかる接触式スイッチは、例えば物品運搬用の移動車の
横側面部又は前後側面部に装着されて、他物との接触や
作業者が触れたことを検出するのに用いられることにな
り、そして、その検出情報は、移動車を非常停止させる
制御情報として利用される。Such a contact switch is installed, for example, on the side or front and rear sides of a moving vehicle for transporting goods, and is used to detect contact with another object or touch by a worker. , the detection information is used as control information to bring the moving vehicle to an emergency stop.

〔発明が解決しようとする課題〕
従来の場合、作業者が手でスイッチ部材を押す等、他物
が大きな接触面をもってスイッチ部材を押した際に、ス
イッチ部材の接点を切り側に付勢する弾性付勢力に起因
する反発力がかなり大きなものとなり、スイッチ部材を
入り操作するには大きな操作力を有する不利があった。Conventionally, when the mobile vehicle is equipped with a contact switch, a bumper body made of an elastic member is fixed to the vehicle body, a switch member is attached to the front side of the bumper body, and a switch member is installed. It was configured so that it could be directly pushed and operated by another object. (For example, 1987-
(See Publication No. 182713) [Problems to be Solved by the Invention] Conventionally, when an operator presses a switch member with his hand or another object presses the switch member with a large contact surface, the contact of the switch member is cut off. The repulsive force caused by the elastic urging force to the side becomes quite large, and there is a disadvantage in that it requires a large operating force to turn on and operate the switch member.
本発明は、上記実情に鑑みて為されたものであって、そ
の目的は、他物が大きな接触面をもって押し操作する際
にも、適確な検出作動を行゛えるようにする点にある。The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable accurate detection operation even when another object is pressed with a large contact surface. .
本発明による接触式スイッチの特徴構成は、一次元方向

イッチ操作部材は、前記スイッチ部材の接点が連続する
方向に沿って間隔を隔てて並ぶ複数個のスイッチ操作用
突部を備えている点にある。The contact type switch according to the present invention has a characteristic configuration including a switch member having a contact point that is continuous in a one-dimensional direction or two-dimensional direction and is elastically biased toward the cut side, and a switch member that is disposed opposite to the switch member and has a contact point that is continuous in one or two dimensions and is elastically biased toward the cut side. a switch operating member that is elastically biased toward the side away from the switch member, and the switch operating member includes a plurality of switch operating protrusions arranged at intervals along the direction in which the contacts of the switch member are continuous. The point is that it has the following.
又、スイッチ操作部材の具体構造は、次に述べるように
するとよい。Further, the specific structure of the switch operating member is preferably as described below.
すなわち、前記スイッチ操作部材が、剛性を有する本体
のスイッチ操作側の面に前記スイッチ操作用突部を連設
して構成されている。In other words, the switch operation member is configured such that the switch operation protrusion is continuously provided on the switch operation side surface of a rigid main body.
又、別の具体構造としては、前記スイッチ操作部材が、
複数個のスイッチ操作用突起部のうちの一部のものを前
記スイッチ部材側へ変位させることができるように、撓
み変形自在に構成されている。Moreover, as another specific structure, the switch operation member is
It is configured to be flexible and deformable so that some of the plurality of switch operation protrusions can be displaced toward the switch member.
上記構成による作用は次の通りである。 The effects of the above configuration are as follows.
すなわち、他物や作業者が接触式センサを押すと、スイ
ッチ部材とスイッチ操作部材とが接近し、それに伴い、
スイッチ操作用突部がスイッチ部材を押し操作して、ス
イッチ部材が入り操作されることになる。That is, when another object or a worker presses the contact sensor, the switch member and the switch operating member come close to each other, and as a result,
The switch operating protrusion pushes the switch member, and the switch member is turned on and operated.
そして、スイッチ操作用突部は、スイッチ部材の接点が
連続する方向に沿って間隔を隔てて並ぶものであるから
、換言すれば、スイッチ部材をスイッチ操作用突部にて
局部的に押し操作するものであるから、他物が大きな接
触面をもって接触式スイッチを押したとしても、スイッ
チ部材の接点を切り側に付勢する弾性付勢力に起因する
反発力は小さなものとなる。Since the switch operating protrusions are arranged at intervals along the direction in which the contacts of the switch member are continuous, in other words, the switch member can be locally pushed and operated by the switch operating protrusions. Therefore, even if another object presses the contact switch with a large contact surface, the repulsive force resulting from the elastic biasing force that biases the contact of the switch member toward the cut side will be small.
従って、他物が大きな接触面をもって押し操作する際に
も、スイッチ部材の反発力が小さいが故に、小さな押し
操作力で適確に作動されることができる。Therefore, even when a push operation is performed by another object with a large contact surface, since the repulsive force of the switch member is small, the switch member can be operated appropriately with a small push operation force.
