Description

この発明は、高圧架線等を対象にした間接活線作業にて用いられる間接活線工具に関し、特に高圧架線等の被把持物を把持するための工具に関する。 The present invention relates to an indirect hot wire tool used in indirect hot wire work for high voltage overhead wires and the like, and more particularly to a tool for gripping an object to be gripped such as high voltage overhead wires.

高圧架線等の被把持物を電柱等の柱状立設体の柱上で把持するための工具としては、例えば特許文献１等に示されるホットハンド（間接活線把持工具や絶縁ヤットコとも称される。以下、同じ。）を用いるのが一般的である。 As a tool for grasping an object to be grasped such as a high-voltage overhead line on a pillar of a columnar standing body such as a utility pole, for example, a hot hand (also referred to as an indirect live wire grasping tool or an insulating jacket) shown in Patent Document 1 or the like The same shall apply hereinafter).

そして、電柱やその他の柱状立設体の柱上等に作業のために登った位置で、高圧架線等の被把持物に対してホットハンドの先端に配置された把持具を接近させる方向が決まってしまう場合があり、その作業位置や把持具を接近させる方向によっては無理な姿勢で高圧架線等の被把持物を把持する作業が強いられるおそれがある。そして、このような無理な姿勢で高圧架線等の被把持物を把持する作業を行うと、作業の煩雑化や長時間化ひいては作業をする者の体力の消耗を招き、不慮の事故の原因になる可能性もあった。 The direction in which the gripping tool placed at the tip of the hot hand approaches the object to be gripped, such as a high-voltage overhead wire, at the position climbed for work on the pole of the electric pole or other columnar standing body is determined. Depending on the work position and the direction in which the gripping tool is approached, there is a risk that the work of gripping an object to be gripped such as a high-voltage overhead wire may be forced. And if you do the work of grasping the object to be grasped such as high voltage overhead wire in such an unreasonable posture, the work will become complicated and the time will be consumed, and the physical strength of the person who will work will be consumed, causing an unexpected accident There was also a possibility.

この点、特許文献２に示される間接活線把持工具は、間接活線把持工具の先端部に配置された把持具を高圧架線等の被把持物に接近させるときに、高圧架線等の被把持物に把持具を接近させる角度が適切でないと判断した場合には、把持具の絶縁操作棒から延びる軸線に対して遠近する方向への傾斜角度を調整することが可能な角度調整手段を有した構成となっている。 In this regard, the indirect live wire gripping tool disclosed in Patent Document 2 grips a high-voltage overhead wire or the like when a gripping tool arranged at the tip of the indirect live wire gripping tool is brought close to a gripped object such as a high-pressure overhead wire. In the case where it is determined that the angle at which the gripping tool approaches the object is not appropriate, an angle adjusting means capable of adjusting the inclination angle of the gripping tool in a direction approaching or contracting with respect to the axis extending from the insulating operation rod is provided. It has a configuration.

しかしながら、特許文献２に示される間接活線把持工具が有する角度調整手段の構成では、把持具の傾斜角度の調整をするために、作業をする者の手元まで把持具を持って来なければならないので、高圧架線等の被把持物を把持する作業を一時的に中断しなければならず、間接活線作業全体の非能率化が生ずるという不具合がある。 However, in the configuration of the angle adjusting means of the indirect live-line gripping tool shown in Patent Document 2, the gripping tool must be brought to the hand of the person who performs the work in order to adjust the tilt angle of the gripping tool. Therefore, the work of grasping the object to be grasped, such as a high-voltage overhead wire, must be temporarily interrupted, resulting in inefficiency of the entire indirect hot wire work.

また、特許文献２に示される間接活線把持工具では、把持具の傾斜角度の調整手段しか有しないので、把持具を絶縁操作棒から延びる軸線を回転中心として回転させることができず、無理な姿勢での作業の解消を図るのに必ずしも十分ではなかった。 In addition, since the indirect live-line gripping tool disclosed in Patent Document 2 has only a means for adjusting the inclination angle of the gripping tool, the gripping tool cannot be rotated about the axis extending from the insulating operation rod, which is impossible. It was not always enough to eliminate work in posture.

更に、特許文献２に示される間接活線把持工具では、把持具の開閉動作を行うための伝達機構として、従来の間接活線把持工具と同様に絶縁操作棒と作動棒との２本の棒状部材を必要とする構成となっていた。 Furthermore, in the indirect live-line gripping tool disclosed in Patent Document 2, as a transmission mechanism for performing the opening / closing operation of the gripping tool, as in the case of the conventional indirect live-line gripping tool, two bar shapes of an insulating operation bar and an operating bar are used. It was the structure which requires a member.

そこで、本発明は、棒状部材の軸方向の一方端に配置された先端部に対し、手元の操作部で操作することにより、棒状部材から延びる軸線に対して遠近する方向への傾斜角度の調整と、棒状部材から延びる軸線を回転中心とした回転との少なくともいずれかを行うことを可能とすると共に、先端部に配された把持部を開閉し、先端部の傾斜角度を調整し、更には先端部を回転させるための伝達手段を１本の棒状部材に集約した間接活線把持工具を提供することを目的とする。 Therefore, the present invention adjusts the inclination angle in a direction far from or near the axis extending from the rod-like member by operating the tip portion arranged at one end in the axial direction of the rod-like member with the operation unit at hand. And at least one of rotation about the axis extending from the rod-like member as a rotation center, opening and closing the grip portion disposed at the tip portion, adjusting the tilt angle of the tip portion, and An object of the present invention is to provide an indirect hot-line gripping tool in which transmission means for rotating the tip end portion are integrated into a single rod-shaped member.

この発明に係る間接活線把持工具は、直線状に延びる棒状部材と、この棒状部材の長手方向の先端側に配された先端部とを有し、前記先端部は一対の把持部を備え、前記把持部が相対的に遠近することでこれらの把持部の間に配された把持対象物を把持することが可能な間接活線把持工具において、前記先端部は、前記棒状部材が有する操作部による操作によって、前記棒状部材から延びる軸線に対して遠近する方向への傾斜と、前記棒状部材から延びる軸線を回転中心とした回転との少なくとも一方の動作を行うことが可能であり、前記操作部の操作を前記先端部に伝達するための伝達機構は、前記棒状部材に集約されており、前記伝達機構は、前記先端部とは反対側に配される台座と、この台座よりも前記先端部側に配された第１の変位部材と、この第１の変位部材よりも前記先端部側に配され、前記操作部が設けられる第２の変位部材と、この第２の変位部材よりも前記先端部側に配され、前記先端部と連結される第３の変位部材とを有し、これらの台座及び少なくとも第１及び第２の変位部材は、前記棒状部材の内部に設けられた空間に収納され、前記台座と前記第１の変位部材とは、前記台座に対し前記第１の変位部材が前記棒状部材の軸線に対して遠近する方向に傾斜可能に連結され、前記第１の変位部材、前記第２の変位部材及び第３の変位部材は、前記第２の変位部材の変位が他の変位部材に伝達されて当該他の変位部材が同様に変位するように連結されていると共に、軸棒が前記第１の変位部材、前記第２の変位部材及び前記第３の変位部材を貫通して延び、前記操作部は、前記第２の変位部材に一体化されて、前記第２の変位部材を自由な方向に変位させることが可能な第１の操作部を備えていることを特徴としている（請求項１）。一対の把持部は、例えば一方が固定把持部であり、他方が可動把持部である。台座と第１、第２及び第３の変位部材とは、例えば板状、特に円板状の形状をなしている。また、第１の変位部材と第２の変位部材、第２の変位部材と第３の変位部材とは、例えば複数の直線状の連結棒でそれぞれ連結されている。そして、一方の連結棒の一方端と第１の変位部材とは揺動自在に連結され、連結棒の他方端と第２の変位部材とについても揺動自在に連結されていると共に、他方の連結棒の一方端と第２の変位部材とは揺動自在に連結され、連結棒の他方端と第３の変位部材とについても揺動自在に連結されている。 The indirect live-line gripping tool according to the present invention has a linearly extending rod-like member and a tip portion arranged on the tip side in the longitudinal direction of the rod-like member, and the tip portion includes a pair of gripping portions, In the indirect live-line gripping tool capable of gripping a gripping target object disposed between the gripping portions by relatively moving the gripping portion, the tip portion is an operation portion that the rod-shaped member has By the operation according to the above, it is possible to perform at least one of an inclination in a direction in which the axis extends from the rod-shaped member and a rotation about the axis extending from the rod-shaped member as a rotation center, The transmission mechanism for transmitting the operation to the distal end portion is concentrated on the rod-shaped member, and the transmission mechanism includes a pedestal arranged on the side opposite to the distal end portion, and the distal end portion rather than the pedestal. First displacement placed on the side A material, a second displacement member that is disposed closer to the distal end than the first displacement member and is provided with the operation portion, and is disposed closer to the distal end than the second displacement member. A third displacement member coupled to the portion, and the pedestal and at least the first and second displacement members are housed in a space provided inside the rod-shaped member, and the pedestal and the first The displacement member is connected to the pedestal so that the first displacement member can be tilted in a direction away from the axis of the rod-shaped member, and the first displacement member, the second displacement member, and the second displacement member The displacement member 3 is connected so that the displacement of the second displacement member is transmitted to the other displacement member so that the other displacement member is similarly displaced, and the shaft rod is connected to the first displacement member. , Extending through the second displacement member and the third displacement member, Operation unit, said integrated into the second displacement member, said second displacement member is characterized in that it comprises a first operating portion that can be displaced in any direction (claim 1). For example, one of the pair of gripping portions is a fixed gripping portion and the other is a movable gripping portion. The pedestal and the first, second, and third displacement members have, for example, a plate shape, particularly a disk shape. Moreover, the 1st displacement member, the 2nd displacement member, the 2nd displacement member, and the 3rd displacement member are each connected with the some linear connection rod, for example. The one end of one connecting rod and the first displacement member are swingably connected, the other end of the connecting rod and the second displacement member are also swingably connected, and the other end One end of the connecting rod and the second displacement member are swingably connected, and the other end of the connecting rod and the third displacement member are also swingably connected.

このように、間接活線把持工具は、作業員の手元に操作部を有するので、操作部を操作することにより伝達機構を介してその操作が先端部まで伝達され、先端部の傾斜角度を調整したり先端部を回転させたりすることの少なくともいずれか一方が可能となり、これらの動作を先端部に行わせるために先端部を手元まで引き寄せる必要がなくなる。そして、先端部を動作させるための伝達機構は、棒状部材に集約されているので、この棒状部材以外に先端部を動作させるための棒体を必要としなくなる。 In this way, the indirect hot-line gripping tool has an operation part at the hand of the operator, so that the operation is transmitted to the tip part via the transmission mechanism by operating the operation part, and the inclination angle of the tip part is adjusted. It is possible to perform at least one of cutting and rotating the tip portion, and it is not necessary to draw the tip portion close to the hand in order to cause the tip portion to perform these operations. And since the transmission mechanism for operating a front-end | tip part is concentrated on the rod-shaped member, the rod body for operating a front-end | tip part other than this bar-shaped member becomes unnecessary.

更に、操作部の第１の操作部を持って棒状部材の軸方向に沿って上下方向に変位させることで、第１の操作部が一体化された第２の変位部材が傾斜し、第１の変位部材及び第３の変位部材が同様に傾斜して、第３の変位部材に設けられている先端部も一体的に傾斜する。更にまた、操作部の第１の操作部を持って棒状部材の周方向に沿って左右方向に変位させることで、第１の操作部が一体化された第２の変位部材が回転し、第１の変位部材及び第３の変位部材が同様に回転して、第３の変位部材に設けられている先端部も一体的に回転する。Furthermore, by holding the first operation part of the operation part and displacing it vertically along the axial direction of the rod-like member, the second displacement member integrated with the first operation part is inclined, and the first Similarly, the displacement member and the third displacement member are inclined, and the tip portion provided on the third displacement member is also integrally inclined.

さらに、請求項１に記載の発明に係る間接活線把持工具の一例にあっては、前記操作部は、前記第１の操作部に連結されていると共に前記軸棒に連結されて、前記軸棒を前記棒状部材の軸方向に沿って上下動させて、前記先端部の把持部の開閉を操作することができる第２の操作部を備えていることを特徴としている（請求項２）。Furthermore, in the example of the indirect hot-line gripping tool according to the invention described in claim 1, the operation unit is connected to the first operation unit and to the shaft rod, and the shaft It is characterized by comprising a second operation part which can move the bar up and down along the axial direction of the bar-like member to operate opening and closing of the grip part of the tip part (claim 2).

これにより、台座、第１の変位部材、第２の変位部材、及び第３の変位部材を連結した構成の伝達機構を有していても、操作部の第２の操作部を操作することにより、先端部の把持部を開閉させることが可能である。Thereby, even if it has the transmission mechanism of the structure which connected the base, the 1st displacement member, the 2nd displacement member, and the 3rd displacement member, by operating the 2nd operation part of an operation part It is possible to open and close the grip portion at the tip.

また、この発明に係る間接活線把持工具は、直線状に延びる棒状部材と、この棒状部材の長手方向の先端側に配された先端部とを有し、前記先端部は一対の把持部を備え、前記把持部が相対的に遠近することでこれらの把持部の間に配された把持対象物を把持することが可能な間接活線把持工具において、前記先端部は、前記棒状部材が有する操作部による操作によって、前記棒状部材から延びる軸線に対して遠近する方向への傾斜と、前記棒状部材から延びる軸線を回転中心とした回転との少なくとも一方の動作を行うことが可能であり、前記操作部の操作を前記先端部に伝達するための伝達機構は、前記棒状部材に集約されており、前記伝達機構は、前記棒状部材を、前記先端部と連結された第１の棒状部と、前記操作部が設けられていると共に前記第１の棒状部と軸受を介して回転可能に連結されている第２の棒状部とで構成され、さらに前記第１の棒状部の第２の棒状部側部位が前記操作部のうちの先端部を可動させるための操作部も兼ねていることを特徴としている（請求項３）。一対の把持部は、例えば一方が固定把持部であり、他方が可動把持部である。軸受は、例えばボールベアリングである。そして、第１の棒状部と第２の棒状部とは、わずかな力でも円滑に回転するのではなく、相対的に強く力を加えることで回転するように制動がかかった状態で連結されている。An indirect live-line gripping tool according to the present invention has a linearly extending rod-shaped member and a distal end portion disposed on the distal end side in the longitudinal direction of the rod-shaped member, and the distal end portion has a pair of gripping portions. An indirect live-line gripping tool capable of gripping a gripping object disposed between the gripping portions by relatively moving the gripping portion relatively far, and the rod-shaped member has the tip portion By the operation by the operation unit, it is possible to perform at least one of an inclination in a direction toward and away from the axis extending from the rod-shaped member and a rotation about the axis extending from the rod-shaped member as a rotation center, The transmission mechanism for transmitting the operation of the operation portion to the tip portion is concentrated on the rod-like member, and the transmission mechanism includes the first rod-like portion connected to the tip portion, and the rod-like member; The operation unit is provided And the second rod-shaped portion that is rotatably connected to the first rod-shaped portion via a bearing, and the second rod-shaped portion side portion of the first rod-shaped portion is included in the operation portion. It is also characterized in that it also serves as an operation part for moving the tip part of the above (claim 3). For example, one of the pair of gripping portions is a fixed gripping portion and the other is a movable gripping portion. The bearing is, for example, a ball bearing. The first rod-shaped portion and the second rod-shaped portion are coupled in a state where braking is applied so that the first rod-shaped portion and the second rod-shaped portion are not smoothly rotated even with a slight force but are rotated by applying a relatively strong force. Yes.

このように、間接活線把持工具は、作業員の手元に操作部を有するので、操作部を操作することにより伝達機構を介してその操作が先端部まで伝達され、先端部の傾斜角度を調整したり先端部を回転させたりすることの少なくともいずれか一方が可能となり、これらの動作を先端部に行わせるために先端部を手元まで引き寄せる必要がなくなる。そして、先端部を動作させるための伝達機構は、棒状部材に集約されているので、この棒状部材以外に先端部を動作させるための棒体を必要としなくなる。In this way, the indirect hot-line gripping tool has an operation part at the hand of the operator, so that the operation is transmitted to the tip part via the transmission mechanism by operating the operation part, and the inclination angle of the tip part is adjusted. It is possible to perform at least one of cutting and rotating the tip portion, and it is not necessary to draw the tip portion close to the hand in order to cause the tip portion to perform these operations. And since the transmission mechanism for operating a front-end | tip part is concentrated on the rod-shaped member, the rod body for operating a front-end | tip part other than this bar-shaped member becomes unnecessary.

また、棒状部材のうち作業員の手元にある第２の棒状部の第１の棒状部側部位を持って回転させることにより、第２の棒状部が回転して、第２の棒状部に設けられた先端部も回転する。 Further , the second rod-shaped portion is rotated by holding the first rod-shaped portion of the second rod-shaped portion of the rod-shaped member at the hand of the worker so that the second rod-shaped portion rotates and is provided in the second rod-shaped portion. The tip end is also rotated.

さらに、請求項３に記載の発明に係る間接活線把持工具にあっては、前記伝達機構は、軸棒が前記第１の棒状部と前記第２の棒状部とを貫通して延び、この軸棒の先端部側に第１のブロックが取り付けられると共に前記軸棒の操作部側に第２のブロックが取り付けられ、前記第１のブロックと前記把持部とが連結されると共に前記第２のブロックと前記操作部とが線状部材により連結されて、前記操作部の操作により前記把持部の開閉を操作することができることを特徴としている（請求項４）。把持部の開閉を操作する操作部は、例えば従来と同様のハンドルが用いられている。軸棒に連結された第１のブロックと第２のブロックとは、バネ等の弾性部材により付勢されている。また、線状部材は、例えばワイヤケーブル等である。 Furthermore, in the indirect hot wire gripping tool according to the invention described in claim 3, the transmission mechanism includes a shaft rod extending through the first rod-shaped portion and the second rod-shaped portion, A first block is attached to the tip end side of the shaft rod, a second block is attached to the operation portion side of the shaft rod, the first block and the gripping portion are connected, and the second block is connected. The block and the operation part are connected by a linear member, and the opening and closing of the grip part can be operated by the operation of the operation part ( claim 4 ). For example, a handle similar to a conventional handle is used as an operation unit for operating opening and closing of the gripping unit. The first block and the second block connected to the shaft rod are urged by an elastic member such as a spring. The linear member is, for example, a wire cable.

これにより、伝達機構として、棒状部材が第１の棒状部と第２の棒状部とで構成されていても、第１の棒状部に設けられた操作部を操作することにより、先端部の把持部を開閉させることが可能である。 As a result, even if the rod-shaped member is composed of the first rod-shaped portion and the second rod-shaped portion as the transmission mechanism, the tip portion is gripped by operating the operation portion provided on the first rod-shaped portion. It is possible to open and close the part.

以上のように、本発明によれば、間接活線把持工具は、作業員の手元に操作部を有するので、この操作部を操作することにより伝達機構を介してその操作が先端部まで伝達され、先端部の傾斜角度を調整したり先端部を回転させたりすることの少なくともいずれか一方が可能となり、これらの動作を先端部に行わせるために先端部を手元まで引き寄せなくても良いため、先端部の棒状部材から延びる軸線に対して遠近する方向への傾斜角度を調整したり、棒状部材から延びる軸線を回転中心として先端部を回転させたりするときに、間接活線作業を中止する必要がなくので、間接活線作業の円滑化、効率化を図ることができる。
そして、作業員に対して、被把持物に対して間接活線把持工具の先端部を接近させる際に、作業員に無理な姿勢での作業を強いることがなくなり、この点でも間接活線作業の円滑化、効率化を図ることができると共に作業員の安全性の向上を図ることも可能となる。 As described above, according to the present invention, since the indirect hot wire gripping tool has an operation part at the hand of the worker, the operation is transmitted to the tip part via the transmission mechanism by operating this operation part. Since it is possible to adjust the inclination angle of the tip part or rotate the tip part, and to make the tip part perform these operations, it is not necessary to draw the tip part close to the hand, It is necessary to stop the indirect hot-line operation when adjusting the inclination angle in the direction far from the axis extending from the rod member at the tip or rotating the tip with the axis extending from the rod as the rotation center Therefore, indirect hot-line work can be made smoother and more efficient.
When the tip of the indirect hot wire gripping tool is brought closer to the object to be gripped, the worker is not forced to work in an unreasonable posture. Smoothness and efficiency can be achieved, and the safety of workers can be improved.

特に請求項１に記載の発明によれば、操作部の第１の操作部を持って棒状部材の軸方向に沿って上下方向に変位させることで、第１の操作部が一体化された第２の変位部材を傾斜させ、第１の変位部材及び第３の変位部材も同様に傾斜させて、第３の変位部材に設けられている先端部も同様に傾斜させることができるので、第１の操作部の操作だけで先端部を好適な方向に好適な角度で傾斜させることが可能となる。
また、特に請求項１に記載の発明によれば、操作部の第１の操作部を持って棒状部材の周方向に沿って左右方向に変位させることで、第１の操作部が一体化された第２の変位部材を回転させ、第１の変位部材及び第３の変位部材を同様に回転させて、第３の変位部材に設けられている先端部も同様に回転させることができるので、第１の操作部の操作だけで先端部を回転させることが可能となる。 In particular, according to the first aspect of the present invention, the first operating portion is integrated by moving the first operating portion of the operating portion up and down along the axial direction of the rod-shaped member. The first displacement member and the third displacement member can be similarly inclined, and the tip portion provided on the third displacement member can be similarly inclined. It becomes possible to incline the tip part in a suitable direction at a suitable angle only by operating the operation part.
In particular, according to the first aspect of the present invention, the first operation unit is integrated by holding the first operation unit of the operation unit and displacing it in the left-right direction along the circumferential direction of the rod-shaped member. Since the second displacement member is rotated, the first displacement member and the third displacement member are rotated in the same manner, and the tip provided on the third displacement member can be rotated in the same manner. The tip can be rotated only by operating the first operation unit.

特に請求項２に記載の発明によれば、本発明の間接活線把持工具が、台座、第１の変位部材、第２の変位部材、及び第３の変位部材を連結した構成の伝達機構を棒状部材の内部に収納されていても、操作部の第２の操作部を操作することにより、先端部の把持部を開閉させることが可能であるので、この間接活線把持工具について、把持対象物を把持するための間接活線作業用工具として従来のものと同様に使用することが可能である。 In particular, according to the invention described in claim 2 , the indirect hot-line gripping tool of the present invention includes a transmission mechanism having a configuration in which a base, a first displacement member, a second displacement member, and a third displacement member are connected. Even if it is housed inside the rod-shaped member, it is possible to open and close the grip part at the tip by operating the second operation part of the operation part. It can be used in the same manner as a conventional tool for indirect hot-line work for gripping an object.

特に請求項３に記載の発明によれば、棒状部材のうち作業員の手元にある第２の棒状部の第１の棒状部側部位を持って回転させることにより、第２の棒状部のみが回転して、第２の棒状部に設けられた先端部も回転させることができるので、第２の棒状部の操作だけで先端部を回転させることが可能となる。 In particular, according to the third aspect of the present invention, only the second rod-shaped portion is rotated by holding the first rod-shaped portion side portion of the second rod-shaped portion of the rod-shaped member at the hand of the worker. Since the tip portion provided on the second rod-shaped portion can be rotated by rotation, the tip portion can be rotated only by operating the second rod-shaped portion.

特に請求項４に記載の発明によれば、本発明の間接活線把持工具の伝達機構として、棒状部材が第１の棒状部、中間棒状部、及び第２の棒状部を連結して構成されていても、第１の棒状部に設けられた操作部を操作することにより、先端部の把持部を開閉させることが可能であるので、この間接活線把持工具について、把持対象物を把持するための間接活線作業用工具として従来のものと同様に使用することが可能である。 In particular, according to the invention described in claim 4 , as the transmission mechanism of the indirect hot wire gripping tool of the present invention, the rod-shaped member is configured by connecting the first rod-shaped portion, the intermediate rod-shaped portion, and the second rod-shaped portion. Even if it is, it is possible to open and close the grip part of the tip part by operating the operation part provided in the first rod-like part. Therefore, it can be used as an indirect hot wire working tool in the same manner as a conventional tool.

以下、この発明の実施形態を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図１から図８において、この発明に係る間接活線把持工具１の実施例１が示されている。 1 to 8 show a first embodiment of an indirect hot wire gripping tool 1 according to the present invention.

間接活線把持工具１は、直線状に延びる棒状部材２と、この棒状部材２の長手方向の先端側に配された先端部３とを有している。 The indirect live wire gripping tool 1 has a rod-like member 2 that extends linearly and a tip portion 3 that is disposed on the tip side in the longitudinal direction of the rod-like member 2.

先端部３は、係合部３１のプレート間に挟持固定されて動かないアーム状の固定把持部３２と、下記する軸棒５６に連結されると共に係合部３１間に把持され且つ回転軸３４を介して回動可能に軸支されたアーム状の可動把持部３３とを有して構成されている。可動把持部３３は、通常時では図１から図３に示されるように、固定把持部３２に当接せず開いた状態にあり、軸棒５６が棒状部材２の先端部３とは反対側に移動したときに、固定把持部３２に近づいて当接し図４に示されるように閉じた状態となる。そして、先端部３は、下記する変位部材５４に係合部３１が固定されたものとなっている。 The distal end portion 3 is connected to an arm-shaped fixed holding portion 32 that is sandwiched and fixed between the plates of the engaging portion 31 and does not move, and a shaft rod 56 described below, and is held between the engaging portions 31 and the rotation shaft 34. And an arm-shaped movable gripping portion 33 that is pivotally supported via a shaft. As shown in FIG. 1 to FIG. 3, the movable gripping portion 33 is normally in an open state without contacting the fixed gripping portion 32, and the shaft rod 56 is opposite to the tip end portion 3 of the rod-shaped member 2. When it moves to the position, it approaches the fixed gripping portion 32 and comes into contact with it, as shown in FIG. And the front-end | tip part 3 has the engaging part 31 fixed to the displacement member 54 mentioned below.

棒状部材２は、この実施例では内部に当該棒状部材２の軸方向に沿って延びる円柱状の空間Ｓを有する筒状体であり、少なくとも先端部３側が開口したものとなっている。そして、棒状部材２は、先端部３とは反対側端の近傍において先端部３を可動させるため及び先端部３の把持部３２、３３同士を開閉させるための操作部４と、この操作部４の操作を先端部３に伝達させるための伝達機構５とを有している。 In this embodiment, the rod-shaped member 2 is a cylindrical body having a columnar space S extending along the axial direction of the rod-shaped member 2, and at least the tip 3 side is opened. The rod-shaped member 2 includes an operation unit 4 for moving the tip 3 in the vicinity of the end opposite to the tip 3 and opening and closing the grips 32 and 33 of the tip 3, and the operation unit 4. And a transmission mechanism 5 for transmitting the above operation to the distal end portion 3.

伝達機構５は、図２から図５に示されるように、台座５１、変位部材５２、変位部材５３及び変位部材５４を有している。これらの台座５１及び変位部材５２、５３、５４は、先端部３とは反対側から先端部３に向けて、台座５１、変位部材５２、変位部材５３、変位部材５４の順で配置されている。そして、台座５１、変位部材５２、変位部材５３、変位部材５４は、棒状部材２の円柱状の空間Ｓに下記する軸棒５６を基点として軸方向に揺動可能に収納されるように、円板状をなしていると共に、その外径寸法は棒状部材２の円柱状の空間Ｓの内径寸法よりも所要の幅ほど短くなっている。 As shown in FIGS. 2 to 5, the transmission mechanism 5 includes a pedestal 51, a displacement member 52, a displacement member 53, and a displacement member 54. The pedestal 51 and the displacement members 52, 53, 54 are arranged in the order of the pedestal 51, the displacement member 52, the displacement member 53, and the displacement member 54 from the opposite side to the distal end portion 3 toward the distal end portion 3. . The pedestal 51, the displacement member 52, the displacement member 53, and the displacement member 54 are circularly stored in the columnar space S of the rod-shaped member 2 so as to be swingable in the axial direction with a shaft rod 56 described below as a base point. It has a plate shape, and its outer diameter dimension is shorter than the inner diameter dimension of the cylindrical space S of the rod-like member 2 by a required width.

台座５１は、この実施例では棒状部材２の円柱状の空間Ｓの底面か底部側の側面に固定されているもので、特に図３から図５に示されるように、変位部材５２側の面から当該変位部材５２に向けて延びる突起部５１１を有している。そして、突起部５１１の先端には、略球状の頭部５１２が設けられている。 In this embodiment, the pedestal 51 is fixed to the bottom surface or the side surface on the bottom side of the columnar space S of the rod-shaped member 2, and in particular, as shown in FIGS. 3 to 5, the surface on the displacement member 52 side. A protrusion 511 extending toward the displacement member 52. A substantially spherical head 512 is provided at the tip of the protrusion 511.

変位部材５２は、台座５１側の面に突起部５１１の頭部５１２が挿入することが可能な保持孔５２１が形成されている。この保持孔５２１の窪みの内部形状は、略球状となっており、保持孔５２１の内径寸法は、突起部５１１の頭部５１２の外径寸法とほぼ同じか僅かに大きくなっている。これにより、変位部材５２の保持孔５２１に突起部５１１の頭部５１２を挿入することで、通常の状態では、変位部材５２は台座５１に不動の状態で保持される一方で、変位部材５２に強い力が働いたときには、変位部材５２が頭部５１２を基点として傾いたり回転したりすることができる自在継手が構成される。 The displacement member 52 has a holding hole 521 into which the head 512 of the protrusion 511 can be inserted on the surface on the base 51 side. The inner shape of the recess of the holding hole 521 is substantially spherical, and the inner diameter of the holding hole 521 is substantially the same as or slightly larger than the outer diameter of the head 512 of the protrusion 511. Thus, by inserting the head portion 512 of the projection 511 into the holding hole 521 of the displacement member 52, the displacement member 52 is held in a stationary state by the pedestal 51 in a normal state, while the displacement member 52 When a strong force is applied, a universal joint is configured that allows the displacement member 52 to tilt or rotate with the head 512 as a base point.

変位部材５２は、変位部材５３側の面に複数（この実施例では６つ）の装着孔５２２が周縁近傍において周方向に沿って等間隔で並ぶように形成されている。これらの装着孔５２２の内部形状は、略球状となっており、下記する連結棒５５ｂの球状の頭部５５１が挿入することで、自在継手が構成されるようになっている。なお、この実施例では、各装着孔５２２の内径寸法は保持孔５２１の内径寸法よりも小さくなっている。 The displacement member 52 is formed such that a plurality of (six in this embodiment) mounting holes 522 are arranged at equal intervals along the circumferential direction in the vicinity of the periphery on the surface on the displacement member 53 side. The internal shapes of these mounting holes 522 are substantially spherical, and a universal joint is configured by inserting a spherical head 551 of a connecting rod 55b described below. In this embodiment, the inner diameter of each mounting hole 522 is smaller than the inner diameter of the holding hole 521.

変位部材５３は、操作部４の下記する第１の操作部４１と第２の操作部４２との双方が設けられていると共に、変位部材５１側の面と変位部材５２側の面との双方において、複数（この実施例では６つ）の装着孔５３１ａ、５３１ｂが周縁近傍において周方向に沿って等間隔で並ぶように形成されている。これらの装着孔５３１ａ、５３１ｂの内部形状は、略球状となっており、下記する連結棒５５ａ、５５ｂの球状の頭部５５１が挿入することで、自在継手が構成されるようになっている。なお、この実施例では、各装着孔５３１ａ、３５１ｂの内径寸法は保持孔５２１の内径寸法よりも小さくなっている。そして、変位部材５３の中心には、軸棒５６が挿通する貫通孔５３２が形成されている。 The displacement member 53 includes both a first operation unit 41 and a second operation unit 42 described below of the operation unit 4, and both a surface on the displacement member 51 side and a surface on the displacement member 52 side. In FIG. 5, a plurality (six in this embodiment) of mounting holes 531a and 531b are formed in the vicinity of the peripheral edge so as to be arranged at equal intervals along the circumferential direction. The internal shapes of these mounting holes 531a and 531b are substantially spherical, and a universal joint is configured by inserting spherical heads 551 of connecting rods 55a and 55b described below. In this embodiment, the inner diameter of each of the mounting holes 531a and 351b is smaller than the inner diameter of the holding hole 521. A through hole 532 through which the shaft bar 56 is inserted is formed at the center of the displacement member 53.

変位部材５４は、変位部材５３側の面に複数（この実施例では６つ）の装着孔５４１が周縁近傍において周方向に沿って等間隔で並ぶように形成されている。これらの装着孔５４１の内部形状は、略球状となっており、下記する連結棒５５ａの球状の頭部５５１が挿入することで、自在継手が構成されるようになっている。すなわち、変位部材５４の装着孔５４１の内径寸法は装着孔５２２、５３１ａ、５３１ｂの内径寸法と同じとなっている。そして、変位部材５４の中心には、軸棒５６が挿通する貫通孔５４２が形成されている。 The displacement member 54 is formed such that a plurality (six in this embodiment) of mounting holes 541 are arranged on the surface on the displacement member 53 side at equal intervals along the circumferential direction in the vicinity of the periphery. The internal shapes of these mounting holes 541 are substantially spherical, and a universal joint is configured by inserting a spherical head 551 of the connecting rod 55a described below. That is, the inner diameter of the mounting hole 541 of the displacement member 54 is the same as the inner diameter of the mounting holes 522, 531a, and 531b. A through hole 542 through which the shaft bar 56 is inserted is formed at the center of the displacement member 54.

また、伝達機構５は、図２から図５に示されるように、変位部材５２と変位部材５３、変位部材５３と変位部材５４、ひいてはこれらの変位部材５２、５３、５４全体を一体化するように連結するものとして、複数（この実施例では６つ）の連結棒５５ａ、５５ｂを有している。各連結棒５５ａ、５５ｂは、その長手方向の両端に、変位部材５２の装着孔５２２、変位部材５３の装着孔５３１ａ、５３１ｂ及び変位部材５４の装着孔５４１に装着可能な略球状の頭部５５１が設けられている。 Further, as shown in FIGS. 2 to 5, the transmission mechanism 5 integrates the displacement member 52 and the displacement member 53, the displacement member 53 and the displacement member 54, and thus the displacement members 52, 53, and 54 as a whole. There are a plurality (six in this embodiment) of connecting rods 55a and 55b. Each of the connecting rods 55a and 55b has a substantially spherical head 551 that can be mounted in the mounting hole 522 of the displacement member 52, the mounting holes 531a and 531b of the displacement member 53, and the mounting hole 541 of the displacement member 54 at both ends in the longitudinal direction. Is provided.

さらに、伝達機構５は、図２から図５に示されるように、一方端が先端部３と連結され、他方端の近傍部位が操作部４の第２の操作部４２と連結された軸棒５６を有している。この軸棒５６は直線状のもので、その側方周面は変位部材５３の貫通孔５３２の内周面や変位部材５４の貫通孔５４２の内周面に接しないものとなっている。すなわち、変位部材５３の貫通孔５３２や変位部材５４の貫通孔５４２の内径寸法は、軸棒５６の外径寸法よりも所要の幅ほど大きくなっている。 Further, as shown in FIGS. 2 to 5, the transmission mechanism 5 is a shaft bar having one end connected to the tip portion 3 and the vicinity of the other end connected to the second operation portion 42 of the operation portion 4. 56. The shaft rod 56 is linear, and the side circumferential surface thereof does not contact the inner circumferential surface of the through hole 532 of the displacement member 53 or the inner circumferential surface of the through hole 542 of the displacement member 54. That is, the inner diameter dimension of the through hole 532 of the displacement member 53 and the through hole 542 of the displacement member 54 is larger than the outer diameter dimension of the shaft rod 56 by a required width.

操作部４は、図１から図５に示されるように、先端部３を棒状部材２から延びる軸線に対して遠近する方向への傾斜角度を調整したり、先端部３を棒状部材２から延びる軸線を回転中心として回転させたりするための第１の操作部４１と、可動把持部３３を固定把持部３２に遠近する方向に動かして把持部３２、３３を開閉するための第２の操作部４２とを備えている。 As shown in FIGS. 1 to 5, the operation unit 4 adjusts an inclination angle in a direction in which the distal end portion 3 is far from or near the axis extending from the rod-shaped member 2, or extends the distal end portion 3 from the rod-shaped member 2. A first operation unit 41 for rotating about an axis as a rotation center, and a second operation unit for opening and closing the gripping units 32 and 33 by moving the movable gripping unit 33 in a direction approaching or moving away from the fixed gripping unit 32 42.

第１の操作部４１は、図６や図７にも示されるように、変位部材５３の径方向に突出したハンドルとなっており、変位部材５３と一体化されていると共にそのハンドルの形状は手で握りやすくするため等から例えば円柱状となっている。もっとも、第１の操作部４１のハンドルとしての形状を四角柱状や六角柱状等の多角柱形状としても良い。 As shown in FIGS. 6 and 7, the first operation unit 41 is a handle protruding in the radial direction of the displacement member 53, and is integrated with the displacement member 53 and the shape of the handle is For example, it has a cylindrical shape so that it can be easily grasped with a hand. However, the shape of the handle of the first operation unit 41 may be a polygonal column shape such as a quadrangular column shape or a hexagonal column shape.

第２の操作部４２は、この実施例では、グリップ４２１と、２つの弾性部材４２２、４２３と、作用部４２４とで構成されている。 In this embodiment, the second operation unit 42 includes a grip 421, two elastic members 422 and 423, and an action unit 424.

グリップ４２１は、作業員が握るための部分で、この実施例では作業員の手の指が４本入る通孔４２１ａが形成されている。作用部４２４は、グリップ４２１の基端から斜め方向に延びる作用部本体４２４ａと、この作用部本体４２４ａの先端から２つに分岐した分岐部４２４ｂ、４２４ｂとを有し、分岐部４２４ｂ、４２４ｂ間に回転軸４２４ｃが架設されている。回転軸４２４ｃは、図３から図５に示されるように、軸棒５６に形成された軸孔５６１に挿通されて、第２の操作部４２は、第１の操作部４１に遠近する方向に揺動可能となっている。 The grip 421 is a part for an operator to grip, and in this embodiment, a through hole 421a into which four fingers of the operator's hand are inserted is formed. The action part 424 has an action part main body 424a extending in an oblique direction from the base end of the grip 421, and branch parts 424b and 424b branched into two from the tip of the action part main body 424a, and between the branch parts 424b and 424b. A rotating shaft 424c is installed on the shaft. As shown in FIGS. 3 to 5, the rotation shaft 424 c is inserted into the shaft hole 561 formed in the shaft rod 56, so that the second operation unit 42 is in a direction away from the first operation unit 41. It can swing.

また、作用部本体４２４ａは、グリップ４２１とで逆Ｖ字状になっている。そして、第２の操作部４２は、グリップ４２１と作用部本体４２４ａとの境界で逆Ｖ字の頂部となる箇所で弾性部材４２２を介して連結されていると共に、グリップ４２１の作用部本体４２４ａ側に近い部位で弾性部材４２３を介して連結されている。 Further, the action portion main body 424a is in an inverted V shape with the grip 421. The second operation portion 42 is connected via an elastic member 422 at a portion where the top of the inverted V shape is located at the boundary between the grip 421 and the action portion main body 424a, and the action portion main body 424a side of the grip 421. It is connected via an elastic member 423 at a portion close to.

弾性部材４２２は例えば板バネであり、弾性部材４２３は例えばコイルバネであるが、その種類は問わない。すなわち、弾性部材４２２は、第２の操作部４２のグリップ４２１と作用部本体４２４ａとの境界部位を第１の操作部４１側に引っ張る力が働いていると共に、弾性部材４２２は、第２の操作部４２のグリップ４２１を第１の操作部４１から離れる方向に押す力が働くものであれば良い。 The elastic member 422 is, for example, a leaf spring, and the elastic member 423 is, for example, a coil spring. That is, the elastic member 422 has a force that pulls the boundary portion between the grip 421 of the second operation portion 42 and the action portion main body 424a toward the first operation portion 41, and the elastic member 422 Any force that pushes the grip 421 of the operation unit 42 in a direction away from the first operation unit 41 may be used.

これにより、第２の操作部４２は、通常時においては、図２に示されるように、グリップ４２１の先端側が弾性部材４２３により第１の操作部４から離れた状態となっており、第２の操作部４２のグリップ４２１を握って第１の操作部４１側に近接させることで、第２の操作部４２はグリップ４２１と作用部本体４２４ａとの境界部位が支点となって、いわゆる梃子の原理により、作用部４２４の分岐部４２４ｂが先端部３とは反対側に移動しようとする力が生ずる。 As a result, in the normal state, the second operation unit 42 is in a state where the distal end side of the grip 421 is separated from the first operation unit 4 by the elastic member 423 as shown in FIG. By gripping the grip 421 of the operation portion 42 and bringing it closer to the first operation portion 41 side, the boundary portion between the grip 421 and the action portion main body 424a serves as a fulcrum for the second operation portion 42. According to the principle, a force is generated in which the branch portion 424b of the action portion 424 tries to move to the side opposite to the tip portion 3.

そして、これらの第１の操作部４１及び第２の操作部４２は、特に図１（ｂ）に示されるように、棒状部材２の側面に開口部２１を設け、この開口部２１から外部に出されるようになっている。棒状部材２の開口部２１の内径寸法は、第１の操作部４１を操作するときのスペースを確保するために相対的に大きなものとなっている。このため、図１（ｃ）に示されるように、開口部２１から外部に出された第１の操作部４１及び第２の操作部４２を覆うようにカバー２２を棒状部材２に装着して、開口部２１から棒状部材２の内部の空間Ｓに異物が侵入しないようにしても良い。 And these 1st operation parts 41 and 2nd operation part 42 provide the opening part 21 in the side surface of the rod-shaped member 2, especially as FIG.1 (b) shows, and this exterior part 21 is outside. It has come out. The inner diameter dimension of the opening 21 of the rod-like member 2 is relatively large in order to ensure a space when operating the first operating portion 41. For this reason, as shown in FIG. 1C, the cover 22 is attached to the rod-shaped member 2 so as to cover the first operation portion 41 and the second operation portion 42 that are exposed to the outside from the opening 21. The foreign matter may not enter the space S inside the rod-shaped member 2 from the opening 21.

以上の構成に基づき、操作部４の第１の操作部４１、第２の操作部４２の操作による把持部３２、３３の開閉や、先端部３の可動について、図３、図４及び図５を用いて説明する。 Based on the above configuration, the opening and closing of the gripping portions 32 and 33 and the movement of the distal end portion 3 by the operation of the first operation portion 41 and the second operation portion 42 of the operation portion 4 are shown in FIGS. Will be described.

図３では、第２の操作部４２のグリップ４２１が握られていない態様が示されており、この態様では、第２の操作部４２のグリップ４２１は、弾性部材４２３により図３の白抜き矢印の方向に付勢されているため、第２の操作部４２の作用部４２４の分岐部４２４ｂに対し図３の矢印方向に力が働き、分岐部４２４ｂ、４２４ｂ間に架設された回転軸４２４ｃで第２の操作部４２と連結された軸棒５６は図３の矢印方向に移動した状態となっている。よって、先端部３の把持部３２、３３は開いた状態となる。 FIG. 3 shows a state in which the grip 421 of the second operation unit 42 is not gripped. In this mode, the grip 421 of the second operation unit 42 is shown by the white arrow in FIG. 3 by the elastic member 423. 3, a force acts in the direction of the arrow in FIG. 3 on the branch portion 424b of the action portion 424 of the second operation portion 42, and the rotary shaft 424c installed between the branch portions 424b and 424b. The shaft bar 56 connected to the second operation unit 42 is in a state of moving in the direction of the arrow in FIG. Therefore, the gripping portions 32 and 33 of the distal end portion 3 are in an open state.

これに対し、図４に示されるように、第２の操作部４２のグリップ４２１を握った態様では、第２の操作部４２に対して弾性部材４２３の押す力に抗して図４の白抜き矢印の方向に力が働くため、第２の操作部４２の作用部４２４の分岐部４２４ｂに対し図４の矢印方向に力が働き、分岐部４２４ｂ、４２４ｂ間に架設された回転軸４２４ｃで連結された軸棒５６は図４の矢印方向（先端部３とは反対側）に移動する。よって、先端部３の把持部３２、３３は閉じた状態となる。 On the other hand, as shown in FIG. 4, in a mode in which the grip 421 of the second operation unit 42 is gripped, the white operation of FIG. 4 is performed against the pressing force of the elastic member 423 against the second operation unit 42. Since a force acts in the direction of the pull-out arrow, a force acts in the direction of the arrow in FIG. 4 on the branch portion 424b of the action portion 424 of the second operation portion 42, and the rotary shaft 424c installed between the branch portions 424b and 424b. The connected shaft rod 56 moves in the direction of the arrow in FIG. 4 (the side opposite to the tip 3). Therefore, the gripping portions 32 and 33 of the distal end portion 3 are in a closed state.

そして、先端部３を棒状部材２から延びる軸線に対して例えば操作部４とは反対側に遠ざかる方向に傾斜させたい場合には、第１の操作部４２のみを持って例えば図５の矢印方向（先端部３側の方向）に傾斜させる。これにより、操作部４２と一体化されている変位部材５３は第１の操作部４２と同じように傾斜する。そして、変位部材５２、変位部材５４は、連結棒５５ａ、５５ｂを介して変位部材５３と連結されているので、変位部材５３と同じように傾斜する。 When the tip 3 is inclined with respect to the axis extending from the rod-shaped member 2 in a direction away from the operation unit 4, for example, only the first operation unit 42 is held, for example, in the direction of the arrow in FIG. Inclined in the direction toward the tip 3. Thereby, the displacement member 53 integrated with the operation unit 42 is inclined in the same manner as the first operation unit 42. And since the displacement member 52 and the displacement member 54 are connected with the displacement member 53 via connecting rod 55a, 55b, it inclines similarly to the displacement member 53. As shown in FIG.

なお、先端部３を棒状部材２から延びる軸線に対して例えば操作部４側に遠ざかる方向に傾斜させたい場合には、第１の操作部４２のみを持って例えば図５の矢印方向とは反対方向（先端部３側とは反対方向）に傾斜させれば良い。また、先端部３を棒状部材２から延びる軸線を回転中心として回転させたい場合には、図示しないが、第１の操作部４２のみを持って棒状部材２の周方向に沿って左右方向のいずれかに動かせば良い。更には、第１の操作部４２のみを持って動かす際にひねりを入れることで、先端部３に対してより複雑な動きを与えることも可能である。 When it is desired to incline the distal end portion 3 with respect to the axis extending from the rod-shaped member 2 in a direction away from the operation portion 4, for example, it has only the first operation portion 42 and is opposite to the arrow direction in FIG. 5, for example. What is necessary is just to incline in the direction (direction opposite to the front-end | tip part 3 side). Further, when it is desired to rotate the tip 3 with the axis extending from the rod-shaped member 2 as the center of rotation, although not shown, only the first operating portion 42 is provided and the left-right direction is changed along the circumferential direction of the rod-shaped member 2. Move it. Furthermore, it is also possible to give a more complicated movement to the distal end portion 3 by adding a twist when moving only with the first operation portion 42.

よって、棒状部材２の作業員の手元にある第１の操作部４１を操作するのみで、先端部３を所望の方向に傾けさせたり、回転させたりすることが可能となる。 Therefore, it is possible to incline or rotate the tip 3 in a desired direction only by operating the first operation unit 41 at the hand of the rod-shaped member 2.

第２の操作部４２の構成について図３から図５を用いて説明してきたが必ずしもこれに限定されず、図６に示される第２の操作部４２や図７に示される第２の操作部４２を用いても良い。但し、図３から図５に示される第２の操作部４２の構成と同じ構成については、同一の符号を付してその説明を省略する。 Although the configuration of the second operation unit 42 has been described with reference to FIGS. 3 to 5, the configuration is not necessarily limited thereto, and the second operation unit 42 illustrated in FIG. 6 and the second operation unit illustrated in FIG. 42 may be used. However, the same components as those of the second operation unit 42 shown in FIGS. 3 to 5 are denoted by the same reference numerals and description thereof is omitted.

図６に示される第２の操作部４２は、通孔４２１ａを有するグリップ４２１と作用部４２４の作用部本体４２４ａとで略逆Ｖ字状となっていること、作用部本体４２４ａの先に分岐部４２４ｂ、４２４ｂを有すること、第１の操作部４２とは作用の異なる弾性部材４２２、弾性部材４２３で連結されていることについては同じである。 The second operation portion 42 shown in FIG. 6 has a substantially inverted V shape between the grip 421 having the through hole 421a and the action portion main body 424a of the action portion 424, and branches to the tip of the action portion main body 424a. It has the same about having the parts 424b and 424b, and being connected by the elastic member 422 and the elastic member 423 which are different in action from the first operation part 42.

すなわち、分岐部４２４ｂに装着孔４２４ｄを形成し、軸棒５６の側面から突出した突部５６２にこの分岐部４２４ｂの装着孔４２４ｄを装着することにより、第２の操作部４２は、軸棒５６に対し第１の操作部４１に遠近する方向に揺動可能に取り付けることが可能となっている。 That is, the mounting hole 424d is formed in the branch portion 424b, and the mounting hole 424d of the branch portion 424b is mounted on the protruding portion 562 protruding from the side surface of the shaft rod 56. On the other hand, it can be attached so as to be swingable in the direction closer to the first operation portion 41.

これにより、図６に示される第２の操作部４２を用いた場合にも、グリップ４２１を握っていない場合には把持部３２、３３は開いた状態となり、グリップ４２１を握ったときには把持部３２、３３は閉じた状態となる。 Accordingly, even when the second operation unit 42 shown in FIG. 6 is used, when the grip 421 is not gripped, the gripping portions 32 and 33 are opened, and when the grip 421 is gripped, the gripping portion 32 is held. , 33 are closed.

図７に示される第２の操作部４２は、通孔４２１ａを有するグリップ４２１と作用部４２４の作用部本体４２４ａとで略逆Ｖ字状となっていること、第１の操作部４２とは弾性部材４２３で連結されていることについては同じである。 The second operation portion 42 shown in FIG. 7 has a substantially inverted V shape between the grip 421 having the through hole 421a and the action portion main body 424a of the action portion 424. The connection with the elastic member 423 is the same.

その一方で、作用部４２４は、作用部本体４２４ａの先端が半円状となっていると共にこの半円状部分に複数の凹凸が放射状に形成されて、ギヤ４２４ｅを有したものとなっている。ギヤ４２４ｅの中心を通る通孔に連結部材４２９の軸部が挿通されることにより、第１の操作部４２とはこの連結部材４２９によっても連結部材４２９の軸部を中心として揺動可能に連結されている。また、棒状部材２の側面には複数の凹凸が直線状に形成されて、ラック５６３を有したものとなっている。さらに、作用部４２４と棒状部材２との間に円板状のギヤ４２５が配置されている。このギヤ４２５は、作用部４２４のギヤ４２４ｅ及び棒状部材２のラック５６３の双方と噛み合うことができる。そして、ギヤ４２５の中心に通孔４２５ａが形成されると共に棒状部材２に通孔５６４が形成され、これらの通孔４２５ａと通孔５６４とに環状の線状部材４２６が挿通されている。このため、ギヤ４２５は、ラック５６３から外れることなく回転することが可能となっている。 On the other hand, the action part 424 has a gear 424e in which the tip of the action part main body 424a has a semicircular shape and a plurality of irregularities are radially formed in the semicircular part. . By inserting the shaft portion of the connecting member 429 through the through hole passing through the center of the gear 424e, the first operating portion 42 is also connected to the first operating portion 42 so as to be swingable about the shaft portion of the connecting member 429. Has been. In addition, a plurality of projections and depressions are linearly formed on the side surface of the rod-like member 2 and have a rack 563. Further, a disc-shaped gear 425 is disposed between the action portion 424 and the rod-shaped member 2. The gear 425 can mesh with both the gear 424 e of the action portion 424 and the rack 563 of the rod-like member 2. A through hole 425 a is formed at the center of the gear 425 and a through hole 564 is formed in the rod-like member 2, and an annular linear member 426 is inserted into the through hole 425 a and the through hole 564. For this reason, the gear 425 can rotate without detaching from the rack 563.

このような第２の操作部４２の構成とすることにより、図７に示される状態ではグリップ４２１が開いており、把持部３２、３３も開いているが、グリップ４２１を図７の白抜き矢印に示される方向（先端部３側）に動かすことで、作用部４２４のギヤ４２４ｅを有する部位は下方に動き、ギヤ４２５は反時計回りに回転するので、ギヤ４２５と噛み合うラック５６３は図７の矢印に示されるように先端部３とは反対側に移動する。よって、先端部３の把持部３２、３３は閉じた状態となる。 By adopting such a configuration of the second operation portion 42, the grip 421 is open and the grip portions 32 and 33 are also open in the state shown in FIG. 7, the part having the gear 424 e of the action part 424 moves downward, and the gear 425 rotates counterclockwise. Therefore, the rack 563 that meshes with the gear 425 is shown in FIG. As indicated by the arrow, it moves to the side opposite to the tip 3. Therefore, the gripping portions 32 and 33 of the distal end portion 3 are in a closed state.

これにより、図７に示される第２の操作部４２を用いた場合にも、グリップ４２１を握っていない場合には把持部３２、３３は開いた状態となり、グリップ４２１を握ったときには把持部３２、３３は閉じた状態となるので、グリップ４２１を握ったり離したりする操作で把持部３２、３３を開閉することが可能となっている。 Accordingly, even when the second operation unit 42 shown in FIG. 7 is used, when the grip 421 is not gripped, the gripping portions 32 and 33 are opened, and when the grip 421 is gripped, the gripping portion 32 is held. , 33 are in a closed state, so that the grip portions 32, 33 can be opened and closed by an operation of grasping or releasing the grip 421.

図８では、伝達機構５を構成する台座５１及び変位部材５２の変形例として、変位部材５２が変位した姿勢を保持するための構成が示されている。以下、この台座５１及び変位部材５２の変形例について説明する。但し、先の実施例と同様の構成については同一の符号を付してその説明を省略する。 In FIG. 8, as a modification of the pedestal 51 and the displacement member 52 constituting the transmission mechanism 5, a configuration for holding the posture in which the displacement member 52 is displaced is shown. Hereinafter, modified examples of the base 51 and the displacement member 52 will be described. However, the same components as those in the previous embodiment are denoted by the same reference numerals, and the description thereof is omitted.

台座５１は、棒状部材２の底面や側面に固定されておらず、棒状部材２の軸方向に移動可能となっていると共に、ロック棒５１３が棒状部材２の側面に開口した開口部２３から外部に突出している。そして、このロック棒５１３は、図８（ａ）に示される開口部２３の先端部３側端に移動したときにロックされ、図８（ｂ）に示される開口部２３の先端部３とは反対側に移動したときにロックが解除されるようになっている。また、台座５１から延びる突起部５１１の頭部５１２の先端部３側には、放射状に複数（この実施例では３つ）の突部５１２ａが形成されている。なお、各突部５１２ａは、この実施例では略三角形状をなしているが略台形状であっても良い。 The pedestal 51 is not fixed to the bottom surface or the side surface of the rod-shaped member 2 and can be moved in the axial direction of the rod-shaped member 2, and the lock rod 513 is externally provided from the opening 23 opened on the side surface of the rod-shaped member 2. Protruding. The lock bar 513 is locked when moved to the end 3 side end of the opening 23 shown in FIG. 8A, and is different from the tip 3 of the opening 23 shown in FIG. 8B. The lock is released when moving to the opposite side. A plurality of (in this embodiment, three) protrusions 512a are formed radially on the tip 3 side of the head 512 of the protrusion 511 extending from the base 51. Each protrusion 512a has a substantially triangular shape in this embodiment, but may have a substantially trapezoidal shape.

変位部材５２は、保持孔５２１の内部形状の内径寸法が頭部５１２の外径形状よりも大きく採られていると共に、放射状に複数（この実施例では３つ以上）の窪み５２１ａが形成されている。窪み５２１ａは、突部５１２ａと略同じ形状をなし、頭部５１２に形成された突部５１２ａの全てが挿入可能な配置となっている。 The displacement member 52 has an inner diameter of the holding hole 521 that is larger than the outer diameter of the head 512, and a plurality of (in this embodiment, three or more) recesses 521a are formed radially. Yes. The recess 521a has substantially the same shape as the protrusion 512a, and is arranged such that all of the protrusions 512a formed on the head 512 can be inserted.

そして、台座５１と変位部材５２との間には例えばコイルバネ等の弾性部材５７が介在している。この弾性部材５７は、図８（ａ）の白抜き矢印に示されるように、台座５１を変位部材５２から離す方向に押圧している。 An elastic member 57 such as a coil spring is interposed between the pedestal 51 and the displacement member 52. The elastic member 57 presses the pedestal 51 in the direction away from the displacement member 52 as indicated by the white arrow in FIG.

以上の構成により、台座５１をロックしていない状態では、図８（ａ）に示されるように、台座５１は弾性部材５７により変位部材５２から離れる方向に押されているので、突起部５１１の頭部５１２は、保持孔５２１内において、突部５１２ａがいずれの窪み５２１ａにも挿入されない状態で配置されている。このため、変位部材５２は台座５１に固定されていないので、変位部材５２を傾斜させたり、回転させたりと自由に動かすことが可能である。すなわち、第１の操作部４１を有する変位部材５３を自由な方向に傾斜させることが可能である。 With the above configuration, when the pedestal 51 is not locked, the pedestal 51 is pushed away from the displacement member 52 by the elastic member 57 as shown in FIG. The head 512 is disposed in the holding hole 521 in a state where the protrusion 512a is not inserted into any of the recesses 521a. For this reason, since the displacement member 52 is not fixed to the pedestal 51, the displacement member 52 can be freely moved, for example, tilted or rotated. That is, it is possible to incline the displacement member 53 having the first operation unit 41 in any direction.

そして、変位部材５２、５３を所望の角度に傾斜させた場合には、台座５１のロック棒５１３を持って弾性部材５７に抗するかたちで先端部３側に押し上げる。これにより、突起部５１１の頭部５１２は、突部５１２ａが窪み５２１ａに挿入されて、変位部材５２、５３の動作が止められると共に、台座５１がロックされることでその状態が保持される。 When the displacement members 52 and 53 are tilted to a desired angle, the displacement members 52 and 53 are pushed up toward the distal end portion 3 while holding the lock rod 513 of the base 51 and resisting the elastic member 57. Thereby, the protrusion 512a is inserted into the recess 521a, the movement of the displacement members 52 and 53 is stopped, and the state of the pedestal 51 is locked.

よって、先端部３をどう動かすか決まっていない場合には、ロック棒５１３を先端部３とは反対側に動かして台座５１のロックを解除すれば、変位部材５２は自由な状態にあるので、変位部材５３に設けられた第１の操作部４１を持って好適な方向に動かすときに、頭部５１２と保持孔５２１との摩擦抵抗で円滑に動かない等の状態が生じない。 Therefore, if it is not determined how to move the tip 3, the displacement member 52 is in a free state if the lock 51 is moved to the opposite side of the tip 3 to unlock the pedestal 51. When the first operation portion 41 provided on the displacement member 53 is held and moved in a suitable direction, a state in which it does not move smoothly due to the frictional resistance between the head 512 and the holding hole 521 does not occur.

これに対して、先端部３の傾斜角度や回転後の向きが決定した場合には、ロック棒５１３を先端部３に動かして台座５１をロックすれば、先端部３の傾斜角度や回転後の向きが保持されて、先端部３に外部から力が不用意に加わる等しても先端部３がずれることがなくなる。 On the other hand, when the inclination angle of the distal end portion 3 and the orientation after rotation are determined, if the pedestal 51 is locked by moving the lock bar 513 to the distal end portion 3, the inclination angle of the distal end portion 3 or Even if the orientation is maintained and force is applied to the tip 3 from the outside, the tip 3 will not be displaced.

図９において、この発明に係る間接活線把持工具１の実施例２が示されている。以下、この間接活線把持工具１について説明する。但し、先の実施例１と同様の構成については同一の符号を付してその説明を省略する。 FIG. 9 shows an embodiment 2 of the indirect hot-line gripping tool 1 according to the present invention. Hereinafter, the indirect hot wire gripping tool 1 will be described. However, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

この間接活線把持工具１の棒状部材２は、棒状部６と棒状部７との２つの部材で構成されている。そして、棒状部６に操作部４の第２の操作部４１が設けられていると共に棒状部７に先端部３が設けられている。第２の操作部４１は、この実施例では回転軸４２７とこの回転軸４２７に回転可能に取り付けられたハンドル４２８とで成る公知のものであり、このハンドル４２８を握って棒状部材２に接近させることにより、後述するように、把持部３２と把持部３３とが閉じ、ハンドル４２８を離すことにより、ハンドル４２８が棒状部材２から離れて把持部３２と把持部３３とが開くようになっている。 The rod-like member 2 of the indirect live wire gripping tool 1 is composed of two members, a rod-like portion 6 and a rod-like portion 7. The rod-like portion 6 is provided with the second operation portion 41 of the operation portion 4 and the rod-like portion 7 is provided with the tip portion 3. In this embodiment, the second operation unit 41 is a known unit including a rotation shaft 427 and a handle 428 rotatably attached to the rotation shaft 427. The second operation unit 41 grips the handle 428 to approach the rod-shaped member 2. Thus, as will be described later, the gripping portion 32 and the gripping portion 33 are closed, and by releasing the handle 428, the handle 428 is separated from the rod-shaped member 2 and the gripping portion 32 and the gripping portion 33 are opened. .

そして、棒状部６と棒状部７とは、この実施例では棒状部７の棒状部６側端にこの棒状部７の周方向に延びる環状の窪み７１が形成されていると共に棒状部６の棒状部７側端には棒状部７の窪み７１に装着可能なフック部６１が形成されている。また、棒状部７の棒状部６側と棒状部６の棒状部７側との間には、ボールベアリング等から成る軸受８が介在されている。もっとも、棒状部６と棒状部７とは、軸受８が介在してもわずかな力で円滑に回転することはなく、相対的に強く力を加えることで回転するように制動がかかった状態で連結されている。 In this embodiment, the rod-shaped portion 6 and the rod-shaped portion 7 are formed with an annular recess 71 extending in the circumferential direction of the rod-shaped portion 7 at the end of the rod-shaped portion 7 on the side of the rod-shaped portion 6. A hook portion 61 that can be attached to the recess 71 of the rod-like portion 7 is formed at the end of the portion 7. Further, a bearing 8 made of a ball bearing or the like is interposed between the rod-shaped portion 6 side of the rod-shaped portion 7 and the rod-shaped portion 7 side of the rod-shaped portion 6. However, the rod-like portion 6 and the rod-like portion 7 do not rotate smoothly with a slight force even when the bearing 8 is interposed, but in a state where braking is applied so as to rotate by applying a relatively strong force. It is connected.

さらに、棒状部６、７内にはその軸方向に延びる空間６２、７２がそれぞれ形成されており、これらの空間６２、７２の双方を貫通するかたちで軸棒９が棒状部６、７内に挿入されている。また、空間６２の先端部３側と空間７２の第２の操作部４２側とには、棒状部６、７の径方向寸法が相対的に拡大された拡大空間部６２ａ、７２ａが設けられている。この軸棒９の長手方向の両端には、略球状の頭部９１が設けられ、さらに各頭部９１には略円柱状のブロック１０が取り付けられおり、これらのブロック１０は拡大空間部６２ａ又は拡大空間部７２ａ内に収納されている。 Further, spaces 62 and 72 extending in the axial direction are formed in the rod-shaped portions 6 and 7, respectively. The shaft rod 9 is inserted into the rod-shaped portions 6 and 7 so as to penetrate both the spaces 62 and 72. Has been inserted. Further, enlarged space portions 62a and 72a in which the radial dimensions of the rod-like portions 6 and 7 are relatively enlarged are provided on the distal end portion 3 side of the space 62 and the second operation portion 42 side of the space 72. Yes. At both ends in the longitudinal direction of the shaft rod 9, a substantially spherical head 91 is provided, and a substantially columnar block 10 is attached to each head 91, and these blocks 10 are connected to the enlarged space portion 62a or It is stored in the enlarged space portion 72a.

これにより、棒状部７のうち棒状部６側の部位を持って回転させることで、棒状部７ひいてはこの棒状部７の先端に設けられた先端部３を回転させることができる。すなわち、棒状部７は先端部３に回転を伝達する伝達機構５として機能すると共に、棒状部７のうち棒状部６側の部位は操作部４の第１の操作部４１として機能する。 Thus, by rotating the rod-like portion 7 while holding the portion on the rod-like portion 6 side, the rod-like portion 7 and thus the tip portion 3 provided at the tip of the rod-like portion 7 can be rotated. That is, the rod-shaped portion 7 functions as the transmission mechanism 5 that transmits the rotation to the tip portion 3, and the portion of the rod-shaped portion 7 on the rod-shaped portion 6 side functions as the first operation portion 41 of the operation portion 4.

そして、軸棒９の第２の操作部４２側のブロック１０は、拡大空間部６２ａ内において先端部３とは反対側に設けられた角度調整のためのローラ１０１との間にワイヤロープ等の線状部材１０２が張られていると共に、この線状部材１０２の先端は第２の操作部４２の回転軸４２７に連結されている。さらに、ブロック１０と拡大空間部６２ａの先端部３とは反対側の面との間にコイルバネ等の弾性部材１０３が介在している。この弾性部材１０３はブロック１０を先端部３側に押圧している。 And the block 10 by the side of the 2nd operation part 42 of the axial rod 9 is between the roller 101 for angle adjustment provided in the opposite side to the front-end | tip part 3 in the expansion space part 62a, such as a wire rope. The linear member 102 is stretched, and the tip of the linear member 102 is connected to the rotation shaft 427 of the second operation unit 42. Further, an elastic member 103 such as a coil spring is interposed between the block 10 and the surface of the expansion space 62a opposite to the tip 3 thereof. The elastic member 103 presses the block 10 toward the distal end portion 3 side.

また、軸棒９の先端部３側のブロック１０は、ワイヤケーブル等の線状部材１０４が取り付けられており、この線状部材１０４は、角度調整のための回転軸３４のローラ３４ａの周面に接した後、固定把持部３２の先端側まで延び、この固定把持部３２内に入り込んだ可動把持部３３に連結されている。さらに、ブロック１０と拡大空間部７２ａの先端部３側の面との間にコイルバネ等の弾性部材１０５が介在している。この弾性部材１０５はブロック１０を先端部３側に引っ張っている。 Further, a linear member 104 such as a wire cable is attached to the block 10 on the distal end portion 3 side of the shaft rod 9, and this linear member 104 is a peripheral surface of the roller 34a of the rotating shaft 34 for angle adjustment. After being in contact with the fixed grip portion 32, it extends to the distal end side of the fixed grip portion 32, and is connected to the movable grip portion 33 that enters the fixed grip portion 32. Further, an elastic member 105 such as a coil spring is interposed between the block 10 and the surface on the distal end portion 3 side of the enlarged space portion 72a. The elastic member 105 pulls the block 10 toward the tip 3 side.

さらにまた、可動把持部３３とローラ３４ａとの間にはコイルバネ等の弾性部材１０６が取り付けられている。この弾性部材１０６は、可動把持部３３をローラ３４ａ側に引っ張っている。 Furthermore, an elastic member 106 such as a coil spring is attached between the movable gripping portion 33 and the roller 34a. The elastic member 106 pulls the movable gripping portion 33 toward the roller 34a.

これにより、ハンドル４２８を握って棒状部材２に近接させた場合には、回転軸４２７が回転して線状部材１０４が弾性部材１０３に抗してブロック１０を第２の操作部４２側に引っ張り、これにより軸棒９を介して他方のブロック１０も弾性部材１０５に抗して第２の操作部４２側に引っ張られるため、可動把持部３３の固定把持部３２に入り込んだ部位が引っ張られるので、可動把持部３３の先端が固定把持部３２側に移動して把持部３２と把持部３３とが閉じる。 As a result, when the handle 428 is grasped and brought close to the rod-shaped member 2, the rotation shaft 427 rotates and the linear member 104 resists the elastic member 103 and pulls the block 10 toward the second operation portion 42. As a result, the other block 10 is also pulled toward the second operating portion 42 side against the elastic member 105 via the shaft 9, so that the portion that has entered the fixed grip portion 32 of the movable grip portion 33 is pulled. The tip of the movable gripping portion 33 moves to the fixed gripping portion 32 side, and the gripping portion 32 and the gripping portion 33 are closed.

これに対し、ハンドル４２８を離した場合には、軸棒９に取り付けられたブロック１０、１０がいずれも弾性部材１０３、１０５によって先端部３側に移動すると共に、弾性部材１０６が可動把持部３３を固定把持部３２とは反対側に引っ張り続けていることにより、可動把持部３３が固定把持部３２から離れて、把持部３２と把持部３３とが開く。 On the other hand, when the handle 428 is released, the blocks 10 and 10 attached to the shaft rod 9 are all moved toward the distal end portion 3 by the elastic members 103 and 105, and the elastic member 106 is moved to the movable gripping portion 33. Is continuously pulled away from the fixed gripping portion 32, the movable gripping portion 33 is separated from the fixed gripping portion 32, and the gripping portion 32 and the gripping portion 33 are opened.

よって、これらの軸棒９、ブロック１０、線状部材１０２、１０４、弾性部材１０３、１０５等も、把持部３２と把持部３３とを開閉させるための伝達機構５として機能する。 Therefore, the shaft rod 9, the block 10, the linear members 102 and 104, the elastic members 103 and 105, and the like also function as the transmission mechanism 5 for opening and closing the grip portion 32 and the grip portion 33.
