Description

本発明は、物体を掴む掴み器に関する。   The present invention relates to a gripper for gripping an object.

従来、地面に落ちているゴミを掴むために用いられる掴み器として、互いに開閉する一方の掴みアームと他方の掴みアームより成る物体掴み部を柄の一端側に有し、柄の他端側に設けられた開閉レバーを握ると掴みアームが閉方向に動き、開閉レバーの握りを解くと掴みアームが開方向に動くように構成されたものが知られている(例えば、特許文献1を参照)。   Conventionally, as a gripping device used for gripping dust falling on the ground, an object gripping part composed of one gripping arm and the other gripping arm that open and close each other is provided on one end side of the handle, and on the other end side of the handle. It is known that the gripping arm moves in the closing direction when the provided opening / closing lever is gripped, and the gripping arm moves in the opening direction when the opening / closing lever is released (see, for example, Patent Document 1). .

実開平3−3966号公報Japanese Utility Model Publication No. 3-3966

しかしながら、上記特許文献1に記載の掴み器では、開閉レバーの操作に応じて掴みアームが動くようにするために一方の掴みアームと開閉レバーとをワイヤで接続する必要があるとともに、開閉レバーの握りを解くと掴みアームが開方向に動くようにするために復帰スプリングを設ける必要があり、構造が複雑になるという問題があった。   However, in the gripping device described in Patent Document 1, it is necessary to connect one gripping arm and the opening / closing lever with a wire so that the gripping arm moves in response to the operation of the opening / closing lever. When the grip is released, it is necessary to provide a return spring in order to move the gripping arm in the opening direction, and there is a problem that the structure becomes complicated.

本発明は、こうした問題に鑑みてなされたものであり、掴みアームを開閉するための操作を簡単な構造で実現することができる掴み器を提供することを目的とする。   The present invention has been made in view of these problems, and an object thereof is to provide a gripper capable of realizing an operation for opening and closing a grip arm with a simple structure.

上記目的を達成するためになされた第1発明の掴み器は、第1回転軸を中心にして、物体を挟持する挟持位置と、物体の挟持を解除する挟持解除位置との間で回転可能に互いが連結された一対の第1挟持部材と第2挟持部材と、第1挟持部材と第2挟持部材が挟持位置となるように第1挟持部材と第2挟持部材を付勢する付勢部材と、第1回転軸を挟んで、第1挟持部材と第2挟持部材により物体が挟持される側とは反対側に配置されるようにして第2挟持部材に取り付けられ、使用者により把持される第1把持部材とを備え、第1挟持部材において物体を挟持する側の先端部を第1挟持先端部とし、第2挟持部材において物体を挟持する側の先端部を第2挟持先端部として、第1回転軸と第1挟持先端部との間の距離は、第1回転軸と第2挟持先端部との間の距離よりも長いことを特徴とする。   The gripper of the first invention, which has been made to achieve the above object, can rotate between a clamping position for clamping an object and a clamping release position for releasing the clamping of the object around the first rotation axis. A pair of first and second clamping members connected to each other, and a biasing member that biases the first and second clamping members so that the first and second clamping members are in the clamping position. And is attached to the second clamping member so as to be disposed on the side opposite to the side where the object is clamped by the first clamping member and the second clamping member across the first rotation shaft, and is gripped by the user. A first gripping member, and a tip portion on the side of the first clamping member that sandwiches the object is a first sandwiching tip portion, and a tip portion of the second clamping member that sandwiches the object is a second sandwiching tip portion. The distance between the first rotating shaft and the first clamping tip is the first rotating shaft and the second Wherein longer than the distance between the lifting tip.

このように構成された掴み器では、一対の第1挟持部材と第2挟持部材が、第1回転軸を中心にして、物体を挟持する挟持位置と、物体の挟持を解除する挟持解除位置との間で回転可能に互いが連結され、付勢部材が、第1挟持部材と第2挟持部材が挟持位置となるように第1挟持部材と第2挟持部材を付勢する。   In the gripper configured as described above, the pair of first and second clamping members includes a clamping position where the object is clamped around the first rotation axis, and a clamping release position where the clamping of the object is released. The biasing member biases the first clamping member and the second clamping member so that the first clamping member and the second clamping member are in the clamping position.

このため、まず、付勢部材の付勢力に抗する力を第1挟持部材と第2挟持部材に作用させることにより、挟持解除位置となるように第1挟持部材と第2挟持部材を回転させ、さらに、第1挟持部材と第2挟持部材との間に物体を配置した後に、第1挟持部材と第2挟持部材に力が作用しないようにすることにより、付勢部材の付勢力で第1挟持部材と第2挟持部材が挟持位置となるように回転し、第1挟持部材と第2挟持部材とにより物体を挟持することができる。   For this reason, first, by applying a force against the urging force of the urging member to the first clamping member and the second clamping member, the first clamping member and the second clamping member are rotated to reach the clamping release position. Furthermore, after the object is disposed between the first clamping member and the second clamping member, the force is not applied to the first clamping member and the second clamping member, so that the biasing force of the biasing member can The first clamping member and the second clamping member rotate so as to be in the clamping position, and the object can be clamped by the first clamping member and the second clamping member.

そして、使用者により把持される第1把持部材が、第1回転軸を挟んで、第1挟持部材と第2挟持部材により物体が挟持される側とは反対側に配置されるようにして第2挟持部材に取り付けられ、第1回転軸と第1挟持先端部との間の距離は、第1回転軸と第2挟持先端部との間の距離よりも長い。   The first gripping member gripped by the user is arranged on the opposite side to the side where the object is clamped by the first clamping member and the second clamping member with the first rotation shaft interposed therebetween. 2 Attached to the clamping member, the distance between the first rotation shaft and the first clamping tip is longer than the distance between the first rotation shaft and the second clamping tip.

このため、或る面(以下、載置面という)上に載せられている物体を当該掴み器で挟持する場合には、まず、使用者が載置面の上方で第1把持部材を把持して第1挟持部材の第1挟持先端部を載置面に接触させた状態で、第1挟持部材と第2挟持部材が挟持解除位置となるように、使用者が第1把持部材を介して第2挟持部材に対して付勢部材の付勢力に抗する力を作用させることにより、第2挟持部材が挟持解除位置となるように回転し、第1挟持部材と第2挟持部材を挟持解除位置にすることができる。   For this reason, when an object placed on a certain surface (hereinafter referred to as a placement surface) is clamped by the gripper, first, the user grasps the first gripping member above the placement surface. The user holds the first clamping member and the second clamping member in the clamping release position with the first clamping tip of the first clamping member in contact with the mounting surface. By applying a force against the urging force of the urging member to the second clamping member, the second clamping member rotates so as to be in the clamping release position, and the first clamping member and the second clamping member are released from clamping. Can be in position.

その後、載置面上の物体を第1挟持部材と第2挟持部材との間に配置した後に、第2挟持部材に力が作用しないようにすることにより、付勢部材の付勢力で第2挟持部材が挟持位置となるように回転し、第1挟持部材と第2挟持部材とにより物体を挟持することができる。   Thereafter, after the object on the mounting surface is disposed between the first clamping member and the second clamping member, the second clamping member is configured to prevent the force from acting on the second clamping member, so that the second biasing force is applied to the second clamping member. The clamping member rotates so as to be in the clamping position, and the object can be clamped by the first clamping member and the second clamping member.

以上より、このように構成された掴み器によれば、第1回転軸と第1挟持先端部との間の距離が第1回転軸と第2挟持先端部との間の距離よりも長く、且つ、第1把持部材が第2挟持部材に取り付けられているという簡単な構造により、挟持位置と挟持解除位置との間で第1,2挟持部材が回転するように使用者が掴み器を操作することを可能とする。   As described above, according to the gripper configured as described above, the distance between the first rotating shaft and the first sandwiching tip is longer than the distance between the first rotating shaft and the second sandwiching tip. In addition, with a simple structure in which the first gripping member is attached to the second clamping member, the user operates the gripper so that the first and second clamping members rotate between the clamping position and the clamping release position. It is possible to do.

また、第2発明の掴み器は、第1回転軸を中心にして、物体を挟持する挟持位置と、物体の挟持を解除する挟持解除位置との間で回転可能に互いが連結された一対の第1挟持部材と第2挟持部材と、第1挟持部材と第2挟持部材が挟持位置となるように第1挟持部材と第2挟持部材を付勢する付勢部材と、第1回転軸を挟んで、第1挟持部材と第2挟持部材により物体が挟持される側とは反対側に配置されるようにして第1挟持部材および第2挟持部材の何れか一方に取り付けられ、使用者により把持される第2把持部材と、第1挟持部材と第2挟持部材との間に配置され、第2挟持部材における第1挟持部材と対向する側に設けられた第2回転軸を中心にして、第1挟持部材および第2挟持部材が挟持解除位置となるように第1挟持部材と第2挟持部材との間に掛け渡される掛渡位置と、第1挟持部材および第2挟持部材が挟持位置となるように第1挟持部材と第2挟持部材との間の掛け渡しが解除される掛渡解除位置との間で回転する掛渡部材とを備えることを特徴とする。   Further, the gripping device of the second invention is a pair of mutually connected in a rotatable manner between a clamping position for clamping an object and a clamping release position for releasing the clamping of the object, with the first rotation axis as a center. A first clamping member, a second clamping member, a biasing member that biases the first clamping member and the second clamping member so that the first clamping member and the second clamping member are in the clamping position, and a first rotation shaft. It is attached to either the first clamping member or the second clamping member so as to be disposed on the opposite side to the side where the object is clamped by the first clamping member and the second clamping member. The second gripping member to be gripped, disposed between the first sandwiching member and the second sandwiching member, and centered on a second rotating shaft provided on the second sandwiching member on the side facing the first sandwiching member. The first clamping member and the second clamping member so as to be in the clamping release position. (2) The span between the first sandwiching member and the second sandwiching member is released so that the spanning position spanned between the two sandwiching members and the first sandwiching member and the second sandwiching member are in the sandwiching position. And a hanging member that rotates between the hanging release positions.

このように構成された掴み器では、掛渡部材が、第2挟持部材における第1挟持部材と対向する側に設けられた第2回転軸を中心にして、第1挟持部材と第2挟持部材との間に掛け渡される掛渡位置と、掛け渡しが解除される掛渡解除位置との間で回転する。   In the gripping device configured as described above, the first clamping member and the second clamping member are arranged around the second rotation shaft provided on the side of the second clamping member that faces the first clamping member. Rotate between a spanning position spanned between and a spanning release position at which spanning is released.

このため、或る面(以下、載置面という)上に載せられている物体を当該掴み器で挟持する場合には、まず、第1挟持部材と第2挟持部材との間に掛渡部材を掛け渡すことにより、第1挟持部材と第2挟持部材が挟持解除位置になるようにする。その後、使用者が載置面の上方で第2把持部材を把持し、載置面上の物体の上方に掛渡部材が位置するようにして、物体に掛渡部材を押し当てる。これにより、掛渡部材が第2回転軸を中心にして回転し、第1挟持部材と第2挟持部材との間の掛け渡しが解除される。このとき、載置面上の物体は、第1挟持部材と第2挟持部材との間に配置されることになる。このため、付勢部材の付勢力で第1,2挟持部材が挟持位置となるように回転し、第1挟持部材と第2挟持部材とにより物体を挟持することができる。   For this reason, when an object placed on a certain surface (hereinafter referred to as a placement surface) is clamped by the gripper, first, a spanning member is interposed between the first clamping member and the second clamping member. , So that the first clamping member and the second clamping member are in the clamping release position. Thereafter, the user holds the second holding member above the placement surface, and presses the suspension member against the object so that the suspension member is positioned above the object on the placement surface. As a result, the spanning member rotates about the second rotation axis, and the spanning between the first sandwiching member and the second sandwiching member is released. At this time, the object on the placement surface is disposed between the first clamping member and the second clamping member. Therefore, the urging force of the urging member rotates so that the first and second clamping members are in the clamping position, and the object can be clamped by the first clamping member and the second clamping member.

以上より、このように構成された掴み器によれば、第2挟持部材における第1挟持部材と対向する側に設けられた第2回転軸を中心にして回転する掛渡部材が取り付けられているという簡単な構造により、挟持位置と挟持解除位置との間で第1,2挟持部材が回転するように使用者が掴み器を操作することを可能とする。   As described above, according to the gripping device configured as described above, the spanning member that rotates about the second rotation shaft provided on the second clamping member on the side facing the first clamping member is attached. With this simple structure, the user can operate the gripper so that the first and second clamping members rotate between the clamping position and the clamping release position.

A first embodiment of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, the gripper 1 has a spring clamp 20 attached to the tip of a rod-shaped handle 10 gripped by a user.

バネ挟み20は、1対の挟持部材21,22と、バネ部材23とにより構成されている。
まず挟持部材21,22は、例えば合成樹脂を材料として一体成形され、互いに対向するように配置される。そして挟持部材21,22は、棒状の柄10における長手方向D1に沿った一端側に、物体を挟持する挟持領域211,221が設けられるとともに、長手方向D1に沿った他端側に、挟持部材21と挟持部材22とを互いに連結するための連結領域212,222が設けられている。なお柄10は、挟持部材22の連結領域222に取り付けられている。
The spring clamp 20 includes a pair of clamping members 21 and 22 and a spring member 23.
First, the clamping members 21 and 22 are integrally molded using, for example, a synthetic resin as a material, and are disposed so as to face each other. The clamping members 21 and 22 are provided with clamping regions 211 and 221 for clamping an object on one end side along the longitudinal direction D1 of the rod-shaped handle 10 and at the other end side along the longitudinal direction D1. Connection areas 212 and 222 are provided for connecting 21 and the clamping member 22 to each other. The handle 10 is attached to the connection region 222 of the holding member 22.

また、挟持部材22の連結領域222における、挟持部材21と対向する側には、回転軸AR1となる円筒状の突起31が形成された突条32が設けられている。なお、円筒状の突起31の円筒軸(すなわち、回転軸AR1)は、挟持部材21,22において互いに対向する面に対して平行になるように配置される。   Further, on the side facing the clamping member 21 in the coupling region 222 of the clamping member 22, a ridge 32 having a cylindrical projection 31 serving as the rotation axis AR1 is provided. The cylindrical axis of the cylindrical protrusion 31 (that is, the rotation axis AR1) is arranged so as to be parallel to the opposing surfaces of the clamping members 21 and 22.

さらに、挟持部材21の連結領域212における、挟持部材22と対向する側には、円筒状の突起31が挿入される軸受孔41が形成された突条42が設けられている。
