[0010] Technical problems to be solved by the utility model

[0011] In use Fig.10 In such conventional remote-operated forceps 100 and the like, if the working method is fixed, only special items need to be prepared, and no major hindrance will be caused to the work.

[0012] However, when the working method is not fixed and various methods must be handled, the remote operation cannot be as free as the manual operation, so there is no other way but to handle the tool in accordance with the working object. In the above case, it may also be forced to adopt a posture that cannot be used to operate the operating rod with the dominant hand, or the operation may become difficult due to reasons such as the length of the operating rod not matching.

[0013] Furthermore, there may be a situation where an attempt is made to use an existing electric tool such as a nut turning tool for remote operation, but there is a cost problem in preparing a dedicated tool depending on the work object.

[0014] Therefore, in the present invention, an object is to provide a remote operation adapter capable of remotely operating an electric tool including a push button switch or an existing pliers-type tool capable of inputting by swinging operation.

[0017] Furthermore, the remote operation adapter of the present invention is characterized in that, based on the above structure, the connecting portion can adjust the angle of the tool gripping portion relative to the supporting rod.

[0018] In addition, the remote operation adapter of the utility model is characterized in that, based on the above-mentioned structure, in a half-circle area on one side of the rotation area of ​​the crank shaft divided into two by an imaginary straight line passing through the free end of the rod and the crank shaft, the crank is connected to the transmission member in a half area on the side opposite to the input part side.

[0019] Furthermore, the remote operation adapter of the present invention is characterized in that, based on the above-mentioned structure, the slider crank portion includes a guide portion that supports the middle portion of the rod so that it can slide.

[0020] Furthermore, the remote control adapter of the present invention is characterized in that, based on the above-mentioned structure, the operating rod can be attached to and detached from the support rod.

[0021] Furthermore, the remote control adapter of the present invention is characterized in that, based on the above-mentioned structure, the transmission member is attachable to and detachable from at least one of the crank and the operating rod.

[0022] Furthermore, the remote operation adapter of the present invention is characterized in that, based on the above-mentioned structure, the transmission member has flexibility at least on the crank side.

[0023] In addition, the remote operation adapter of the utility model remotely operates the input part of the tool grasped by the tool gripping part set at the front end of the supporting rod, and is characterized in that it includes: a slider crank part, which constitutes a slider crank mechanism through a crank and a rod in a manner that can be installed and removed relative to the tool gripping part, and the input part is pressed by pulling in the rod; a transmission component, which is connected to the crank and transmits the force that rotates the crank; and an operating rod, which can be installed and removed relative to the supporting rod and applies tension to the transmission component.

[0025] Furthermore, the remote operation adapter of the present invention is characterized in that, based on the above-mentioned structure, at least the crank side structure of the transmission member has flexibility.

[0026] Utility Model Effect

[0027] As described above, according to the present invention, since a tool having an input portion operable by pressing can be used as a remotely operable tool, the same tool can be used separately according to the working environment.

[0028] Furthermore, according to the present invention, in addition to the above-mentioned effects, it is possible to select a working angle suitable for the shape of the tool to be operated, and it is also possible to change the angle according to the working object in the same tool.

[0029] Furthermore, according to the present invention, in addition to the above-mentioned effects, the rotation area of ​​the crankshaft of the half-circle area divided into two by the imaginary straight line is further divided into two areas, namely, the switch side and the quarter area on the opposite side, and the transmission member is connected to the half on the opposite side of the switch. Thus, even if the angle of the tool grip relative to the support rod is changed, as long as it is within a range of not more than 90 degrees, the rotational force can be transmitted from the transmission member to the crank without changing the connection position of the transmission member relative to the crank.

[0030] Furthermore, according to the present invention, in addition to the above effects, the force can be transmitted to the input part by the action of the swinging slider crank that swings the end of the switch side of the rod around the guide part. Thus, when operating a trigger-type switch or a handle of a pliers-type tool that performs an arc motion, accurate operation can be performed in coordination with the track.

[0031] Furthermore, according to the present invention, in addition to the above effects, if the above configuration is adopted, the operating rod can be rotated around the axis of the support rod to change the mounting angle, thereby enabling the rod to be held at a position that is easy to work in accordance with the working environment.

[0032] In addition, according to the present invention, in addition to the above effects, the three structures of the slider crank portion, the transmission member and the operating rod can be further decomposed. In addition, if the crank and the operating rod can be assembled and disassembled, the transmission member can be easily replaced, and the length adjustment and material change of the transmission member can be achieved.

[0033] Furthermore, according to the present invention, in addition to the above-mentioned effects, even if the operating lever is rotated around the axis of the support rod to a position where the transmission member interferes with the support rod, the flexible portion of the transmission member can be deformed in a manner wound along the support rod, thereby enabling operation without hindering the transmission of force.

[0034] In addition, according to the utility model, since the three structures of the slider crank portion, the transmission member and the operating rod can be integrated and removed, storage and transportation become easy. In addition, it can be used in combination with an existing remote operating rod, so the versatility is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Hereinafter, a remote operation adapter according to an embodiment of the present invention will be described using the drawings.

[0046] Figure 1 This is a front side perspective view of the remote operation adapter of the utility model. In addition, Figure 2 The following are three-dimensional views of the back side of the remote operation adapter of the present invention. The overall schematic structure is described using these two figures. In addition, the remote operation adapter is composed of long strip components. Figure 1 , 2 The middle part is omitted.

[0047] In the remote operation adapter 1 of the present embodiment, a tool grip 2 for holding an electric tool (described later) is connected to a support rod 8 via a connection portion 6. An operating rod 10 for an operator to operate is installed below the support rod 8. A rope 14 is provided between the operating rod 10 and the tool grip 2, and the rope 14 is a transmission member for transmitting a force input from the operating rod 10.

[0048] The tool grip 2 can grip an existing tool. In the structure of this embodiment, it is configured to grip an electric tool described later. With respect to the gripped tool, the force transmitted from the operating rod 10 at a remote position can be converted by a slider crank mechanism and a switch operation can be performed. The slider crank mechanism is composed of a slider crank portion 4 fixed to the front side of the tool grip 2.

[0049] The slider crank portion 4 is screwed to the front side of the tool grip portion 2 via a guide fixing metal member 4f. On the support rod 8 side of the guide fixing metal member 4f, a crank 4a connected to one end of a rope 14 is rotatably provided via a crank shaft 4d. The rope 14 is connected by hooking to a rope locking portion 4g provided on the crank 4a.

[0050] In addition to the rope 14, the crank 4a is also connected to a rod 4b so as to be rotatable. A claw portion 4c bent into an L-shape is formed on the free end side of the rod 4b. In addition, the middle portion of the rod 4b is guided to slide by a guide portion 4e fixed by a guide fixing metal member 4f. The guide portion 4e is formed of a resin material with low friction resistance, and a through hole is formed in the center for the rod 4b to be inserted. Since it is constructed in the above manner, when the rope 14 is pulled by the operating rod 10 below, the rod 4b will slide toward the support rod 8 in conjunction with the rotating crank 4a. Through the above action, the claw portion 4c of the rod 4b can press the switch of the electric tool described later.

[0051] The remote operation adapter 1 of the present embodiment is configured as described above, so that an existing tool can be expanded to a structure capable of remote operation. Therefore, it has high versatility compared to an integrated remote operation tool, and is easy to store and carry.

[0052] Figure 3 1 is a front view of the remote operation adapter in use. Here, a structure equipped with a nut turning tool is shown as an example of an electric tool 50. The electric tool 50 has a gun-type handle 52 and a trigger-type switch 51. The claw portion 4c on the free end side of the rod 4b is arranged in a manner to cover the switch 51. In this way, the existing gun-type electric tool 50 can be configured to be remotely operated using the remote operation adapter 1 of this embodiment.

[0053] Next, the opening and closing structure of the tool grip 2 that accommodates the electric power tool 50 will be described.

[0054] Figure 4 2a is a diagram showing a state where the receiving area of ​​the tool grip portion is opened. If the locking pin 2d is pulled upward, the opening and closing portion 2b can be opened. The opening and closing portion 2b is provided with a gap adjustment screw 2c that can protrude toward the inner side of the receiving portion 2e when closed. When the handle 52 of the electric tool 50 is received in the receiving portion 2e (see Figure 3 ), after closing the opening and closing part 2b and locking it with the locking pin 2d, the gap adjustment screw 2c is pressed in, so that the handle 52 can be stabilized in the accommodating part 2e. If the gap adjustment screw 2c is pressed in as described above, the handle 52 will abut against the back plate 2a provided on the support rod 8 side of the tool grip part 2. The back plate 2a is bent into an L shape, and the upper end is bent into a concave shape, so that the main body 53 of the electric tool 50 can be stably placed (refer to Figure 3 ). Since it is constructed in the above manner, as long as it is a gun-type tool, it can be stably maintained by adjusting the gap regardless of whether the shape is different.

[0055] Next, the operation of the slider crank portion 4 will be described.

[0056] Figure 5 The action of the slider crank portion 4 is shown, wherein: Figure 5 (a) is the main view, Figure 5 (b) is a schematic diagram corresponding to the front view of the slider crank portion. Figure 1 As described above with respect to the schematic structure, the slider crank portion 4 is fixed to the front side of the tool grip portion 2 by means of the guide fixing metal member 4f. Figure 5 As shown in (a), the slider crank mechanism can be said that the crankshaft 4d is integrally fixed to the tool grip 2. Therefore, in order to obtain the same structure, instead of fixing the crankshaft 4d and the guide 4e by a guide fixing metal member 4f, they can be fixed to the tool grip 2 separately.

[0057] The rod 4b is held in the guide portion 4e with the claw portion 4c on the free end side slightly raised. Although not shown here, the trigger-type switch of the power tool is mostly formed to protrude slightly downward to improve the hooking of the finger, so the rod 4b becomes a configuration matching the above-mentioned switch.

[0058] exist Figure 5 (b) schematically shows Figure 5 The crank 4a, rod 4b, claw 4c, crank shaft 4d and rope 14 of the slider crank portion 4 of (a) are shown with the same reference numerals as for the parts corresponding to these structures. In addition, the solid line indicates the configuration of the slider crank portion 4 when the switch is turned off, and the dotted line indicates the configuration when the switch is turned on. Figure 5 As shown in (b), when the rope 14 is pulled down and the rotational force is applied to the crank 4a, the rod 4b is pulled by the crank 4a. In the structure of this embodiment, the middle part of the rod 4b is supported by the guide part 4e so as to be able to slide, so the claw part 4c on the free end side of the rod 4b swings. As shown by the arrow in the figure, the track of the claw part 4c slightly drops downward while being pulled toward the crank 4a side. Since it is constructed in the above manner, the track of the trigger-type switch that performs an arc motion during input is consistent with the track of the claw part 4c of the rod 4b, which can achieve accurate operation.

[0059] Next, the connection portion 6 will be described.

[0060] Figure 6 6 is a perspective view of a disassembled state of the connecting portion 6. The connecting portion 6 has a toothed washer type (Japanese: daisy seat type) joint structure. Thus, by simply loosening the butterfly screw 6a, the angle of the tool grip 2 relative to the support rod 8 can be easily adjusted. If the connecting portion 6 is configured to be attachable to and detachable from at least one of the tool grip 2 and the support rod 8, the storage and transportation of the remote operation adapter 1 will become easy.

[0061] Next, the operation of the crank 4 a accompanying the angular deformation of the connection portion 6 will be described.

[0062] Figure 7 The operation of the slider crank portion 4 is shown in a state where the connecting portion 6 is extended linearly. Figure 7 (a) is the main view, Figure 7 (b) is a schematic diagram corresponding to the front view of the slider crank portion 4. Figure 5 Similarly, the components corresponding to the slider crank portion 4 and the rope 14 are marked with the same reference numerals and shown. In addition, here, for the sake of convenience, the state in which the support rod 8 is lifted up with the tool grip portion 2 as a reference is shown. In addition, the solid line shows the rope 14 in the state in which the connecting portion 6 extends in a straight line, and the dotted line shows the rope 14 in the state in which the connecting portion 6 extends in a straight line. Figure 5 The rope 14 is shown in a state where the connecting portion 6 is bent by 90 degrees.

[0063] The imaginary straight line L1 of the imaginary straight lines L1 and L2 shown by the dashed lines is a straight line passing through the crankshaft 4d and the claw 4c. The rotation area of ​​the crank 4a rotating around the crankshaft 4d is divided into two by the imaginary straight line L1. Each of the half-circle areas divided into two is further divided into two by the imaginary straight line L2 that is orthogonal to the imaginary straight line L1 and passes through the crankshaft 4d. One of the four areas divided into four in the above manner is used as the input area R and is marked with a slash to distinguish it from the other three areas.

[0064] like Figure 7 As shown in (b), the rope 14 is connected to the input area R. In the structure of the present embodiment, in a half-circle area of ​​one of the rotation areas divided into two by an imaginary straight line L1 passing through the crank shaft 4d and the claw portion 4c, the rope 14 is connected within a range of a quarter of the rotation area on the opposite side of the switch (input area R).

[0065] When the connecting portion 6 is bent at 90 degrees, the rope 14 applies a force in the direction indicated by the dotted line. In addition, when the connecting portion 6 is extended at 180 degrees, the rope 14 applies a force in the direction indicated by the solid line. In this way, if the rope 14 is connected to the input area R in advance, a force is applied from the rope 14 in any direction indicated by the solid line and the dotted line, and a rotational torque is generated on the crank 4a according to the relationship with the position of the crank shaft 4d, so that a force can be generated in the rotation direction of the pull rod 4b. Therefore, as long as the range of the bending deformation of the connecting portion 6 is an angle less than 90 degrees, the operation of the electric tool 50 can be achieved without changing the connection position of the rope 14 relative to the crank 4a.

[0066] Next, a method of fixing the operating rod 10 will be described.

[0067] Figure 81 is an enlarged perspective view of the support rod 8 to which the operating rod 10 is mounted. The operating rod 10 of this embodiment is fixed to the support rod 8 via a clamp-type operating rod fixing portion 12. The operating rod 10 is provided with a rope locking portion 10a that can detachably support the rope 14. The operating rod fixing portion 12 is a simple structure that only clamps the support rod 8, so the mounting position of the support rod 8 is not limited to a specific position and can be fixed at any position.

[0068] Fig. 9 The following is a usage example in which the mounting position of the operating lever 10 is changed. Fig. 9 (a) is the overall main view, Fig. 9 (b) is an enlarged view of the interference position of the rope 14 with respect to the support rod 8.

[0069] like Fig. 9 As shown in (a) of FIG. 1 , in the remote operation adapter 1 of this embodiment, a flexible rope 14 is used as a transmission member for transmitting force, so that the operating rod 10 can be installed at a position rotated 180 degrees around the support rod 8. The positional relationship between the support rod 8 and the rope 14 in this state is Fig. 9 (b) shows an enlarged view. By arranging the mounting position of the operating lever 10 on the side opposite to the tool gripping portion 2 via the support rod 8, a portion of the rope 14 is brought into contact with the support rod 8 near the tool gripping portion 2. However, when the operating lever 10 is operated, the rope 14 moves in a manner that slides on the surface of the support rod 8, and therefore, does not hinder the transmission of force.

[0070] If the positions of the rope locking parts 10a and 4g provided on the operating lever 10 and the crank shaft 4a are adjusted in the design stage so as to form a positional relationship in which the rope 14 can contact the smooth surface of the support rod 8, it is also possible to fix the rope 14 to a position such as the support rod 8. Fig. 9 The position is a position more significantly rotated than the position rotated 180 degrees around the support rod 8 as in (a).

[0071] Since the above-mentioned structure is adopted, the position of the operating lever 10 can be freely changed according to the working environment and the posture of the operator. In remote operation, the state of the tool is difficult to be transmitted to the operator, so it is difficult to perform accurate work. However, by finely adjusting the position of the operating lever 10 steplessly, the handling during the operation can be made easier and the working efficiency can be improved.

[0072] As in the above embodiment, the remote operation adapter 1 of the present invention can be easily changed to a remotely operable structure by being assembled to an existing electric tool 50, etc. In addition, it can be attached and detached relative to an existing electric tool, etc., and therefore has the advantage of being easy to store and carry.

[0073] The present invention is not limited to the above-described structure, and also includes the following modifications.

[0074] (1) Although the connection between the support rod 8 and the connecting portion 6 is not described in detail in the above embodiment, the support rod 8 and the connecting portion 6 may be configured to be detachable or integral. If configured to be detachable, the tool grip 2 and the operating rod 10 can be separated from the support rod 8, and since the transmission member is composed of the flexible cord 14, they can be stored very compactly. In this way, the remote operation adapter 1 may also be configured not to include the support rod 8 and the connecting portion 6.

[0075] (2) In the above embodiment, the slider crank portion 4 is fixed to the tool grip portion 2. However, the slider crank portion 4 may be configured to be attachable to and detachable from the tool grip portion 2, and a remote operation adapter that does not include the tool grip portion 2 may be configured by the slider crank portion 4, the transmission member, and the operating rod 10. By configuring as described above, the remote operation adapter can be made more compact.

[0076] (3) In the above embodiment, a structure including a rope 14 as a member for transmitting force from the operating rod 10 to the slider crank portion 4 is illustrated. However, it is not limited to the rope 14, and a transmission member in which rod-shaped members are combined into multiple joints may be used. If constructed in the above manner, the transmission member can be folded at the joint portion when separated from the support rod 8. In addition, it is also possible to replace it with a structure using the following transmission member: a transmission member including a member having flexibility at least on the tool grip portion 2 side (slider crank portion 4 side). If constructed in the above manner, as Fig. 9 As shown, even if the mounting position of the operating lever 10 is changed to a position where the transmission member interferes with the support rod 8 , the operating lever 10 can be flexibly deformed in the vicinity of the tool grip 2 so as to follow the support rod 8 .

[0077] (4) In the above embodiment, the rope 14 is provided as the transmission member. However, a belt member may be used as long as the transmission member has flexibility at least on the tool grip 2 side.

[0078] (5) In the above embodiment, it is shown that Fig. 9 The illustrated configuration is an example in which the rope 14 is slid in the interference region with the support rod 8. However, a configuration in which a guide structure such as a guide rail or a pulley is provided at the interference position may be used.

[0079] (6) In the above embodiment, the claw portion 4c bent in an L shape is formed on the free end side of the rod 4b of the slider crank portion 4. However, any structure that can press the switch of the electric tool 50 is not limited to the L shape bending.

[0080] (7) In the above embodiment, an example is shown in which the guide portion 4e for guiding the swinging and sliding movement of the rod 4b is made of a resin material having a through hole. However, as long as the structure can guide the middle part of the rod 4b to slide, it is not limited to the resin material. For example, a long hole may be formed in the longitudinal direction of the rod 4b, and a pin-shaped member may be inserted through the long hole to guide the swinging and sliding movement. On the contrary, a convex portion may be formed on the side of the rod, and a guide rail in which the convex portion can be embedded may be used as a guide for the swinging and sliding movement.

[0081] (8) In the above embodiment, the structure of the remote operation adapter 1 that can operate the trigger switch 51 of the gun-type electric tool 50 is illustrated. However, the target tool is not limited to the electric tool 50, and it can also be a pliers-type tool. For example, when the claw 4c of the rod 4b is configured in a manner that one side (input part) of the handle of the swinging pliers is pressed in the closing direction, remote operation can also be performed. In the above case, the tool grip 2 can be configured to fix the other side of the handle of the pliers.

[0082] (9) In the above embodiment, a structure in which the rope 14 that transmits force from the operating rod 10 is connected to the rod 4b via the crank 4a is illustrated. However, instead of using the crank 4a to convert the direction of the force transmitted from the rope 14, a roller-shaped guide that changes the extension direction of the rope 14 may be used. In addition, as long as it is a member with a small friction coefficient, it may be a round rod-shaped guide. If the rope 14 is arranged in a manner that slides on a roller-shaped guide or a round rod-shaped guide, and is directly or indirectly connected to the rod 4b, a force that pulls the rod 4b toward the support rod 8 can be generated. In addition, as a similar structure, a motion direction conversion mechanism using a pulley and a belt can also be used. In addition, in the motion direction conversion structure in the above case, the rod 4b does not swing but moves in a straight line.

[0083] If the structure is constructed in the above manner, even if the bending angle of the extension direction (the direction in which the tension acts) changed by the roller-shaped or round rod-shaped guide changes to more than 90 degrees, a constant force can be always transmitted. Figure 5 (a) and Figure 7 (a) The deformation between these two states can also be compared Figure 5 (a) is bent more significantly to move the tool grip 2 closer to the flexed position of the support rod 8.

[0084] Furthermore, instead of providing the roller-shaped guide only on one side with respect to the rope, the configuration may be configured by using at least two roller-shaped guides and sandwiching the rope (transmission member) between these guides.

[0085] If the structure is constructed in the above manner, even if the bending angle of the rope (transmission member) bent by the guide exceeds 180 degrees in the extension direction, the rope can slide (climb) on either of the two guides, so that a fixed force can be stably transmitted. Figure 7 The state (a) further enables the support rod 8 (towards Figure 5 (a) The opposite side of the motor turns back and moves.

[0086] Industrial Applicability
