Description

  The present invention relates to a connection adapter, and more particularly, to an adapter that enables a hand work tool such as pliers to be operated by a remote work tool such as a yatco.

  Conventionally, a YATCO that can grasp a target object at a remote position is known. Using this YATCO, for example, a protective pipe is put on an electric wire installed on a utility pole, or an insulator is screwed to the electric wire. Work, such as removing the nest of crows nested on the top of the utility pole, is being carried out.

  For example, as shown in FIG. 4, a gripping unit 110 that grips a target object, an operation unit 120 that is operated by an operator, and the operation unit 120 that is disposed on the hand side as shown in FIG. And a support transmission unit 130 that is connected to a distal end position at which 110 is separated and transmits an operation force from the operation unit 120 to the grip unit 110 to operate. The gripping part 110 of the YATCO 100 includes a stationary member (rotating member) 111 fixed (connected) to the support bar 131 of the support transmission part 130 and a rotation provided on the support bar 131 of the support transmission part 130. A movable member (rotating member) 112 that is supported (connected) so as to be rotatable about a moving shaft 113 is provided, and the movable member 112 is rotated relative to the non-moving member 111. The respective tip portions can be brought into contact with and separated from each other so that the object can be grasped or separated.

  However, since the Yatco 100 mainly grips the target object with the grip part 110, when it is desired to cut the target object at a remote position, the remote work tool having a cutting function at the position of the grip part 110. When it is assumed that various kinds of work are to be performed, there is a disadvantage that necessary tools are bulky.

  In order to solve this problem, it has been proposed to provide a general general-purpose Yatco 100 with a function such as cutting. For example, one handle (grip part) of a work tool such as a radio pliers is fixed to a mounting part such as a vise that can be attached to the stationary member 111 of the YATCO 100, and the other handle is a movable member of the YATCO 100. It has been proposed that 112 can be opened and closed by contacting and separating (see, for example, Patent Document 1). In the present invention, the spring urging in the separating direction is interposed between the handles, so that the movable member 112 of the YATCO 100 can be opened and closed simply by abutting and separating from one handle.

In addition, a hand work tool has been proposed that can be attached to the immovable member 111 and the movable member 112 of the YATCO 100 and includes an attachment portion that is rotatably connected to individual handles such as radio pliers (for example, a patent) Reference 2).

  However, in such a conventional attachment tool for YATCO, it is not necessary to prepare YATKO for each type of work, but YATCO is used as a work tool used when working at hand such as radio pliers. It is necessary to prepare a dedicated work tool with a dedicated mounting part. For this reason, a special tool is necessary and bulky, and a desired work cannot be performed flexibly unless a special tool for Yatco is prepared and placed.

  Therefore, the present invention realizes that a general work product such as a pliers is attached to a general work product such as a Yatco, so that a desired work can be realized without preparing a dedicated remote work tool. It is an object of the present invention to provide a connection adapter that can be performed flexibly and inexpensively.

A connecting portion that connects the rear end portion of the rotating member of the work tool for each rotating member, a remote work tool that is attached to the connecting portion by the first and second mounting portions, and a hand-operated working tool operate. and and a rotation allowing portion for allowing the respective pivot member rotates when, characterized in that for connecting the rotating member and the rotating member of the local working tools remote work tool is there.

In the first invention, the attachment of the first attachment portion to the distal end portion of the rotation member of the remote work tool, the rear end portion of the rotating member of the local working tool by attaching the second mounting portion, Teleoperation road tool and hand work road implement the respective pivot members are connected to each other through a connecting portion. In this state, when the relative rotation in a direction for opening and closing the rotating member by operating the remote work road tool, likewise the rotating member of local working tool is rotated in a direction relatively closing. At this time, the rotating member of the remote work tool and the rotating member of the hand work tool relatively rotate in the direction to increase or decrease the included angle defined between them. It is absorbed (allowed) by a rotation allowing part such as an elastic material. Therefore, by opening and closing the tip of the rotating member of the remote work tools (separable), it is possible to contact and separation operation of the rotating member of the local working tools and coordinated by operating the local working tools remotely Work Tool , it can be like pinching or cutting the intended product Bei obtain function.

In addition to the specific matters of the first invention, the second invention of the connection adapter that solves the above-mentioned problem is that the connection portion is formed in a shape that internally mounts the attachment counterpart of the attachment portion, while the attachment portion is connected to the connection adapter. It is composed of a female screw that penetrates from the outer surface to the inner surface of the part and a male screw that is screwed into the female screw. It is characterized by maintaining.

  According to the present invention, the rotating member of the gripping part of the remote work tool and the operating part of the rotating member of the hand work tool are tightened in the connecting part by a male screw that is built in the cylindrical connecting part and screwed into the female screw. Fixed by being done. Therefore, even if it is a rotation member which does not have a dent etc. in the other party which presses the front-end | tip of a male screw, it can fix firmly, and a local work tool can be connected and attached to a remote work tool with high reliability.

In addition to the specific matters of the second invention, the third invention of the connection adapter that solves the above-described problem includes a material that prevents the front end side of the male screw from coming into direct contact with the mounting partner to be installed in the connection portion. It is characterized by having made it.

  In the present invention, the tip of the male screw does not directly hit the counterpart rotating member, and it is possible to avoid damaging the counterpart. Accordingly, it is possible to use a hand work tool used in another work place without damaging it.

According to a fourth aspect of the connection adapter for solving the above problem, in addition to the specific matter of the first aspect of the invention, the connection portion is formed in a shape that internally mounts the attachment counterpart of the attachment portion. A through-hole penetrating from the outer surface to the inner surface of the portion, a pin that passes through the through-hole and is inserted into and removed from the connecting portion, and a biasing means that biases the pin in a direction to enter the connecting portion. In this configuration, the mounting state is maintained by engaging the tip end side of the pin with a mounting partner housed in the connecting portion.

  In this invention, the rotating member of the gripping part of the remote work tool and the operating part of the rotating member of the hand work tool are fixed by engaging with a pin that is built in the cylindrical connecting part and protrudes inside. . Therefore, in the case of a rotating member with a recess that can engage the tip of the pin on the other side, it can be attached and detached simply by pulling up the pin, etc., and the hand work tool can be easily connected to the remote work tool. Can be attached.

The fifth invention of the connection adapter that solves the above-mentioned problem is the operation of the gripping portion of the remote work tool and the work of the hand work tool in addition to the specific matters of any of the first to fourth inventions. The operation part of the hand work tool is connected to the grip part of the remote work tool so that the extended surfaces of the rotating surfaces of the parts intersect.

In the present invention, an angle can be given to the direction of the working portion of the operating hand work tool with respect to the extending direction of the remote work tool. Therefore, since the hand work tool is linearly connected to the remote work tool, it is possible to work easily even at a place where the hand work tool is difficult to work depending on the posture of the remote work tool.
As a method of using the connection adapter for solving the above-mentioned problems, two connection adapters are prepared, and the remote work tool to be connected is configured such that a pair of rotating members rotate relatively around a rotation axis. Then, the gripping part that grips the target object with the tip part contacting and separating, the operating part that operates to rotate the rotating member of the gripping part, and the position that is separated from the operating part And a transmission unit that transmits an operation force applied to the operation unit to the gripping unit. The hand work tool to be connected includes a rotating member having a pair of rotating members disposed in the intermediate unit. A working unit constructed so as to be relatively rotatable around a moving shaft and performing operations such as clamping and cutting by operating to pinch the target object when the tip of one end of the rotating member approaches. And the rear end of the other end of the rotating member is the tip of the rotating member. The operation unit is configured to be operated so as to be rotated in the direction in which the unit is brought into and out of contact with each other, whereas the pair of rotating members of the remote work tool and the pair of rotating members of the hand work tool are each in pairs. You may make it connect separately.
Further, as a method of using the connection adapter for solving the above-mentioned problems, two connection adapters are prepared, and the remote work tool to be connected is such that a pair of rotating members are relatively centered around a rotation axis. A gripping part that grips and holds the target object by rotating and moving the tip part away, an operation part that operates to rotate the rotating member of the gripping part, and a position that is separated from the operation part And a transmission unit that transmits an operation force applied to the operation unit to the gripping unit, and the hand work tool to be connected has a pair of rotating members disposed on one end side. It is constructed so as to be relatively rotatable around the rotation axis, and the rear end portion of the other end side of the rotation member is rotated in a direction in which the front end portion side of the rotation member is contacted / separated. It is configured as an operating unit to be operated, and when the operating unit is approached, the tip on the rotating shaft side In contrast to a working unit that performs operations such as clamping and cutting by moving the part side to sandwich the object, the pair of rotating members of the remote work tool and the pair of rotating members of the hand work tool are One set may be connected separately.

  Here, it is preferable that the connecting portion is formed in a cylindrical shape that can accommodate the attachment counterpart of the attachment portion or a sandwiched shape so that the rotation member of the attachment counterpart can be in an interior state. When a variety of mounting partners can be installed, the attachment may be made thicker. In addition, when the mounting partner is deeply installed, the connecting portion may be formed linearly or curved according to the shape of the rotating member on the other side.

  According to the present invention, the remote work tool and the hand work tool can be operated by connecting the operation part of the hand work tool to the grip part of the remote work tool, so the hand work tool is operated by operating the remote work tool. The remote work tool can be connected to different types of hand work tools as necessary. Therefore, it is possible to work appropriately by connecting a hand-operated work tool such as a pliers to a hand-operated remote work tool such as a yatco. As a result, a desired work can be performed flexibly and inexpensively without preparing a dedicated remote work tool for each type of work.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described based on the drawings. FIGS. 1-8 is a figure which shows 1st Embodiment of the connection adapter which concerns on this invention, and its usage method .

  In FIG. 1, the connecting adapter 10 includes a Yatco (remote work tool) 100 shown in FIG. 4, a radio pliers (hand work tool) 200 shown in FIG. 5, a scissor (hand work tool) 300 shown in FIG. 7 is designed to connect a hand tool such as a cutting scissors (hand work tool) 400 shown in FIG. 7, and the Yatco 100 and the radio pliers 200 can be linked to each other when used in pairs. it can.

  First, the YATCO 100 separates the gripping unit 110 that grips an object such as various parts and materials, the operation unit 120 that inputs an operation (force) of the gripping unit 110, and the gripping unit 110 and the operation unit 120. And a support transmission unit 130 that is coupled to the position by a support bar 131 and transmits an operation performed by an operator input to the operation unit 120 to the gripping unit 110 by a transmission bar 132. It is made of an insulating material such as plastic or rubber material to ensure insulation.

  The holding part 110 is formed in an arc shape and is fixed to one end side of the support rod 131 of the support transmission part 130, and is similarly formed in an arc shape and one end of the transmission bar 132 of the support transmission part 130. And a movable member 112 that is pivotally supported around a rotation shaft 113 that is connected to the stationary member 111 and disposed on the stationary member 111 (support bar 131) side. The grip 110 is formed between the rotating shaft 113 by moving the stationary member 111 and the movable member 112 relative to each other about the rotating shaft 113 to bring the tip portions 111a and 112a into contact with and away from each other. It is constructed so that the object can be grasped and grasped in the formed space S or between the tip portions 111a and 112a thereof.

  The operation unit 120 includes a fixture 121 attached to the other end side of the support rod 131 of the support transmission unit 130, and a lever whose one end side is pivotally supported by a rotary shaft 121a disposed in the fixture 121. One end side is pivotally supported on the handle 122 and the rotation shaft 121a of the fixture 121 so as to be coaxial with the lever handle 122, and the other end side is relatively rotatable via the rotation shaft 123a. The connection lever 123 connected to the transmission rod 132 of the support transmission portion 130 and the rotation shaft 121a of the fixture 121 are transmitted to the connection lever 123 and the rotation of the lever handle 122 is transmitted to the support transmission portion 130. A spring material (not shown) that urges the transmission rod 132 to push upward in FIG. 4 (a direction in which the distal ends 111a and 112a of the immovable member 111 and the movable member 112 are separated from each other). When, and is made of.

  Accordingly, when the operator grips and supports the support bar 131 of the support transmission unit 130 and rotates the lever handle 122 of the operation unit 120 in the direction in which the operator approaches the support bar 131, the YATCO 100 transmits the support transmission. When the transmission rod 132 of the portion 130 is pulled downward in FIG. 4 and the movable member 112 of the gripping portion 110 is rotated in the direction approaching the immovable member 111, the tip portions 111a and 112a can be brought closer to each other. The object can be grasped and grasped. On the other hand, when the lever handle 122 is released and the operating force via the transmission rod 132 is released, the transmission rod 132 is pushed upward in FIG. 4 by the elastic force of the spring material, and the movable member 112 does not move. By rotating in a direction away from the member 111, the front end portions 111a and 112a are returned to a natural state.

  Here, the transmission rod 132 of the support transmission portion 130 is provided with a spring 133 in the vicinity of the connection portion with the connection lever 123. The lever handle 122 is rotated to pull the transmission rod 132 to move the movable member 112. When the object is gripped with the stationary member 111 approached, the spring 133 is elastically extended according to the operating force, so that the object can be reliably held and gripped. In addition, the YATCO 100 includes an umbrella cover 134 for dripping moisture from the gripping part 110 side, and an umbrella cover 135 indicating a limit position where the work can be safely performed in consideration of insulation from a work target electric wire or the like. It is provided on the support rod 131 and the transmission rod 132 of the support transmission portion 130.

  Further, as shown in FIG. 5, the radio pliers 200 includes a rotation shaft 203 that is a combination of a shaft shape and a bearing shape formed at an intermediate portion between the pair of rotation members 201 and 202. Rotating members 201 and 202 are connected so as to be relatively rotatable about 203. The rotating members 201 and 202 are tapered and have tapered portions 211 and 212 that are brought into surface contact with the opposing surfaces 211a and 212a, and are opposed to the tapered surfaces 211a and 212a after being bent toward the opposing surfaces 211a and 212a. Grip portions (handles) 221 and 222 that are curved toward the surfaces 211a and 212a are formed so as to be continuous. Between the grip portions 221 and 222 of the rotating members 201 and 202, a spring material (not shown) that biases the tapered portions 211 and 212 in the direction of separating them is interposed.

  Thereby, the radio pliers 200 can hold the object between the opposing surfaces 211a and 212a of the tapered portions 211 and 212 by grasping and bringing the grip portions 221 and 222 close to each other. By releasing the parts 221, 222, the natural state in which the tapered portions 211, 212 are separated is returned. That is, the tapered portions 211 and 212 constitute a working part of the radio pliers 200, and the grip parts 221 and 222 constitute an operation part. The radio pliers 200 are covered so that the grip portions 221 and 222 do not slip when gripped by the cover 204 made of a resin material.

  As in the case of the radio pliers 200, the pair of scissors 300 is connected to a pair of rotating members 301 and 302 so as to be relatively rotatable by a rotating shaft 303 at an intermediate portion, as shown in FIG. 6. The rotating members 301 and 302 include cutting portions 311 and 312 that rub against the opposite sides 311a and 312a, and a grip portion 321 that extends substantially linearly from the opposite sides 311a and 312a of the cutting portions 311 and 312. 322 are formed to be continuous with each other. Between the grip portions 321 and 322 of the rotating members 301 and 302, a spring 305 that biases the cutting portions 311 and 312 in the direction of separating is interposed.

  Thereby, the scissor 300 can cut the target object between the opposite sides 311a and 312a of the cutting parts 311 and 312 by grasping the grip parts 321 and 322 and releasing the gripping force. By releasing the grip portions 321, 322, the cutting portions 311 and 312 are returned to a natural state. That is, the cutting parts 311 and 312 constitute the working part of the scissor 300, and the grip parts 321 and 322 constitute the operation part. The scissors 300 are covered so that the grip portions 321 and 322 do not slip when gripped by the cover 304 made of a resin material.

  In the cutting scissors 400, as shown in FIG. 7, a pair of rotating members 401 and 402 are coupled to each other by a rotating shaft 403 on one end side so as to be relatively rotatable. The rotating members 401 and 402 include cutting portions 411 and 412 that rub against the opposing sides 411a and 412a on the rotating shaft 403 side, and the other end separated from the opposing sides 411a and 412a of the cutting portions 411 and 412. The grip portions 421 and 422 that are curved toward the side are formed so as to be continuous.

  Thereby, the cutting scissors 400 can cut | disconnect a target object between the opposing sides 411a and 412a of the cutting parts 411 and 412 by grasping the grip parts 421 and 422 and making them approach. That is, the cutting parts 411 and 412 constitute the working part of the cutting scissors 400, and the grip parts 421 and 422 constitute the operation part. The cut scissors 400 are covered so that the grip portions 421 and 422 do not slip when gripped by the cover 404 made of a resin material.

  Here, as for the radio pliers 200 and the cutting scissors 300, when the gripping force is released by interposing a spring material between the grip portions 221 to 322, the details 211, 212 and the cutting portions 311 and 312 are natural. Although the case where it has a mechanism separated from each other will be described as an example, the spring material disposed on the rotation shaft 121a of the attachment 121 of the YATCO 100 works when it is connected to the YATCO 100. In particular, it is not necessary to provide a spring material. The cutting scissors 400 may have a mechanism in which a spring material is housed in the rotating shafts 403 of the rotating members 401 and 402 and the cutting portions 411 and 412 are naturally separated when the gripping force is released. Needless to say, it is good.

  Returning to FIG. 1, the connecting adapter 10 is a main body (connecting portion) formed in a tube shape having a diameter capable of incorporating the grip portions 221 to 422 of the radio pliers 200, the cutting scissors 300, and the cutting scissors 400. 11 and a hand tool attaching portion (second fitting) for fixing the gripping portions 221 to 422 such as the radio pliers 200 inserted into the insertion port 12 opened on one end side of the main body portion 11 and maintaining the attachment state therein. (Attachment part) 21 and the other end side (opposite side of the insertion port 12) of the main body part 11 and fixed to the stationary member 111 of the gripping part 110 of the YATCO 100 and the distal end parts 111a and 112a of the movable member 112. And a Yatco mounting portion (first mounting portion) 31 that maintains the mounting state. Here, since the wording of the immovable member 111 of the gripping portion 110 of the YATCO 100 and the front end portions 111a and 112a of the movable member 112 is too redundant, in the following, it will be abbreviated as the front end portions 111a and 112a of the YATCO 100. There is also.

  As shown in FIG. 2, for example, the main body 11 cuts a tube tube having a diameter larger than the grips 221 to 422 such as the radio pliers 200 longer than the grips 221 to 422 and crushes the other end side. The opening on one end side thereof is used as the insertion port 12 of the grip portions 221 and 222. Here, as will be described later, the main body 11 is molded from a stainless steel tube material in order to ensure strength and weather resistance since a force for operating the Yatco 100 may be applied or the work may be performed even in the rain. It is preferable to do this. In addition, since the corner | angular part when this tube pipe | tube is cut | disconnected is exposed and dangerous at the insertion port 12 of this main-body part 11, the tube pipe | tube consisting of elastic materials, such as rubber | gum, is covered as the protective cover 13. .

  The hand tool attaching portion 21 is composed of a nut (female screw) 22 welded to the outer peripheral surface of the main body portion 11 so as to be aligned in the extending direction, and a butterfly screw (male screw) 23 screwed into the nut 22. It is configured. The hand tool mounting portion 21 has a wing screw 23 screwed into a nut 22 and passes through a through hole 14 opened in the outer peripheral surface of the main body portion 11 at the welding position. It is possible to tighten the outer surface of the grip portions 221 to 422 such as the radio pliers 200 in the interior state toward the opposite side. As a result, the hand tool attaching portion 21 is firmly pressed and fixed (coupled) even when there are no attachment recesses on the outer surface of the grip portions 221 to 422 (covers 204 to 404) such as the radio pliers 200. Can do.

  The hand tool mounting portion 21 is a thin metal plate that is interposed between the tip of the thumbscrew 23 and the grip portions 221 to 422 such as the radio pliers 200 and is displaced by being pushed by the tip of the thumbscrew 23. For example, a contact plate 24 made of a copper plate is attached. Thereby, the hand tool attaching part 21 can fix the front-end | tip of the thumbscrew 23, without damaging the outer surface of the covers 204-404 of the grip parts 221-422, such as the radio pliers 200 in the main-body part 11. FIG. it can. The abutting plate 24 extends from the position where the through-hole 14 with which the tip of the thumbscrew 23 abuts to face the outer surface of the main body 11 on the insertion port 12 side, and is screwed. The stop position is covered with a protective cover 13.

  The YATCO mounting portion 31 is a box-shaped housing portion 32 that covers and inserts the front end portions 111a and 112a of the gripping portion 110 of the YATCO 100, and the box-shaped housing portion 32 is detachably fixed to the front end portions 111a and 112a. An attachment / detachment portion 33 that maintains the attachment state and a shaft support portion 34 that pivotally supports the box-shaped housing portion 32 on the other end side of the main body portion 11.

  As shown in FIG. 3, the box-shaped housing portion 32 is formed with an insertion port 35 that opens so as to insert the distal ends 111 a and 112 a of the gripping portion 110 of the YATCO 100 into an interior state. On the upper surface side of the insertion port 35 (upper side in FIG. 3), slits 36 are formed for housing ribs 111b and 112b (only 111b is shown in FIG. 8) formed on both side surfaces of the tip portions 111a and 112a. A detachable portion 33 is disposed between the slits 36.

  The attaching / detaching portion 33 is integrally formed on the upper surface of the box-shaped housing portion 32 and has a through-hole 37 penetrating in the vertical direction. The tip 38 a is formed inside the box-shaped housing portion 32 in the through-hole 37. And an engagement pin 38 that protrudes from the inside of the box-shaped casing 32. Both ends of the engagement pin 38 are fixed to the inner surface of the engagement pin 38 and the through-hole 37, and the tip 38a of the engagement pin 38 is protruded into the box-shaped casing 32. An energizing spring (urging means) 39 is housed. As a result, the attaching / detaching portion 33 picks up the large-diameter portion 38b on the rear end side of the engaging pin 38 and pulls it up against the elastic force of the spring 39. Can be inserted from the insertion port 35 of the box-shaped housing portion 32, and when the large-diameter portion 38b of the engaging pin 38 is released, it is inserted into a recess (not shown) formed on the outer surface of the tip portions 111a and 112a. The front end 38a of the engagement pin 38 can enter (engage) and be separated from the box-shaped housing portion 32 to be fixed.

  The attaching / detaching portion 33 has a locking pin 38c erected on the side surface of the shaft portion of the engaging pin 38, and a slit that accommodates the locking pin 38c in the through hole 37 so as to be movable in the vertical direction. 37a is formed. Accordingly, the engaging pin 38 is rotated after the large-diameter portion 38b is picked up and pulled up so that the locking pin 38c is detached from the slit 37a, whereby the locking pin 38c is rotated on the upper surface (the slit 37a of the slit 37a). The tip 38a can be held in a state where it does not protrude from the inner surface of the box-shaped housing portion 32 even if the operator releases his / her hand. In this state, the leading end portions 111a and 112a of the gripping portion 110 of the Yatco 100 can be easily inserted from the insertion port 35 of the box-shaped housing portion 32, and then the large diameter portion 38b is rotated in the reverse direction. By engaging the locking pin 38c of the engaging pin 38 into the slit 37a, the front end 38a of the engaging pin 38 can be engaged with the recesses on the outer surfaces of the front end portions 111a and 112a of the YATCO 100 and fixed.

  The shaft support part 34 penetrates the through-hole 16 drilled in the crushing part 15 on the other end side of the main body part 11 in the female screw 32 a (shown in FIG. 3) formed on the side surface of the box-shaped housing part 32. The box-shaped housing part 32 is connected to the main body part 11 so as to be rotatable relative to the main body part 11 by screwing the male screw 41. The male screw 41 is screwed into the female screw 32 a of the box-shaped housing portion 32 at the tip side, and a nut 42 is screwed at the same time, and the nut 42 is a side surface of the box-shaped housing portion 32. These screwed states are prevented from being loosened by rotating them so as to be pressed through spring washers 43.
