Description

  The present invention relates to an unlocking tool for a binding band, and more particularly to an apparatus for easily functioning an unlocking function of a binding band even in a narrow work space.

A binding band used for bundling electric wires or the like is known. The binding band is passed through a lock mechanism so that the band portion is wrapped around and tightened on the binding target, so that the lock mechanism keeps the binding state in a locked state that restricts the return of the band portion.
For this type of binding band, by releasing the lock state of the lock mechanism that restricts the return of the band part and allowing the return of the band part, the band part can be removed from the binding target and reused without being cut. The thing is also provided (for example, patent document 1).

This binding band locking mechanism is operated so that the meshing claw that restricts the movement of the band part and the release claw (pick part) that faces the band part are facing the band part, and the release claw is picked together with the band part. By doing so, the engagement with the band portion by the engagement claw is released, and the movement limitation in the return direction is eliminated.
However, since this binding band is provided with a lock mechanism at the end of the band portion, it is necessary to perform an operation of operating the lock mechanism at a position adjacent to the bundled electric wires or the like. For this reason, in such a binding band, for example, it is necessary to perform an operation of picking together the release claw and the band portion of the lock mechanism with a radio pliers having a thin tip.

  This radio pliers must be approached from the direction in which the lock mechanism release claw and the band part can be picked together in a posture (orientation), and if the work space cannot be secured in that direction, It is necessary to pull out the electric wire etc. to the position where it can work. For this reason, depending on the working environment, it may be necessary to cut the band portion. In short, the linear members to be bound by the binding band are in a state of extending in the same direction as the direction in which the radio pliers approach, and there are more situations where there is no work space.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1-3 is a figure which shows one Embodiment of the lock release tool for binding bands which concerns on this invention.
1 and 2, the unlocking tool 10 has an outer cylinder (fixing member) 11 having a fixing protrusion 21, an inner cylinder (sliding member) 15 having a sliding protrusion 25, and the inner cylinder 15 positioned at a home position. The spring (biasing member) 19 that is biased in this way is manufactured in a simple structure that only assembles, and the lock state is released by the lock mechanism that restricts the return of the band portion 52 of the binding band 51 shown in FIG. Operate.
Here, the outer cylinder 11 and the inner cylinder 15 are preferably made of an insulating resin material, and in particular, the outer cylinder 11, the fixed protrusion 21, and the slide protrusion 25 that may come into contact with an operator or work object. In addition, it is effective to ensure the insulation by covering at least the outer surface of the rear end portion 15b of the inner cylinder 15 with an insulating material in order to ensure the safety in operation.

The outer cylinder 11 is formed in a bottomed cylindrical shape (or a square cylinder shape such as a square) having a bottom 11a on the front end side, and the inner cylinder 15 is inserted and received from the opening 11b on the rear end side. The inner cylinder 15 is formed so as to have an inner diameter larger than the outer diameter.
The inner cylinder 15 is formed in a cylindrical shape having an outer diameter that can be inserted into the outer cylinder 11 (may be a columnar bar shape), and when the distal end portion 15a is inserted from the opening 11b of the outer cylinder 11 to the bottom portion 11a. In other words, a part of the rear end portion 15b is exposed. In other words, the rear end portion 15b is sufficiently long to be pushed.

The outer cylinder 11 is integrally formed at a location where a plurality of annular support portions 12a and 12b formed in a rib shape so as to reduce the inner diameter of the inner peripheral surface are separated in the axial direction of the inner peripheral surface. The annular support portions 12a and 12b are formed so that the inner cylinder 15 inserted into the inner cylinder 15 is inserted into and removed from the inner body in a stable posture by forming the inner diameter larger than the outer diameter of the inner cylinder 15 (length direction). ) Slidably supported. Further, the outer cylinder 11 is also formed with an annular support portion 12c at the opening end of the opening portion 11b, and this annular support portion 12c is also on the side of the rear end portion 15b of the inner cylinder 15 inserted therein. Is slidably supported.
In the inner cylinder 15, an annular stopper 16 formed in a rib shape so as to increase the outer diameter of the outer peripheral surface is integrally formed on the rear end 15 b side. The annular stopper 16 is formed so that the outer diameter is smaller than the inner diameter of the inner peripheral surface of the outer cylinder 11 and larger than the inner diameter of the annular support part 12 c, so that it slides in the direction of being pulled out from the outer cylinder 11. In other words, the assembled state is maintained so that the ring support portion 12c does not get out of contact with the ring support portion.

The fixed protrusion 21 is integrally formed in a shape that protrudes by extending the bottom portion 11 a from the end portion of the outer peripheral surface of the outer cylinder 11 in the normal direction.
Similarly, the slide protrusion 25 is integrally formed in a shape that protrudes by extending the distal end portion 15a endmost portion from the outer peripheral surface end portion of the inner cylinder 15 in the normal direction.
A long hole (sliding long hole) 13 parallel to the axis is opened on the outer peripheral surface of the outer cylinder 11 adjacent to the fixed protrusion 21 with the direction toward the opening 11b as the longitudinal direction. The long hole 13 is slidably inserted into the slide protrusion 25 so as to protrude from the outer surface, and has an opening width larger than that of the slide protrusion 25 and is formed to have a length of a separation interval S to be described later.

The spring 19 is formed in a gap between the outer cylinder 11 and the inner cylinder 15 between the annular support portion (inward convex shape) 12 b of the outer cylinder 11 and the annular stopper portion (outward convex shape) 16 of the inner cylinder 15. Containment set. The spring 19 is formed in a spiral shape that generates an urging force that urges the inner cylinder 15 in the direction in which the inner cylinder 15 is detached from the outer cylinder 11 (separation direction), and the annular stopper 16 is connected to the annular support 12c. It hits and stops.
The long hole 13 of the outer cylinder 11 is detached from the state in which the rear end portion 15b of the inner cylinder 15 is pushed and the slide projection 25 is positioned adjacent to the fixed projection 21 by the urging force of the spring 19. It is formed in such a length that it can be slid to the separation interval S to the position where it is urged in the direction to stop the ring stopper 16 against the ring support 12c.

  The outer cylinder 11 has an annular hooking portion 14 formed in a rib shape on the outer peripheral surface in the vicinity of the intermediate portion, and a finger is hooked on the front end side of the annular hooking portion 14 so that the rear end of the inner cylinder 15 The part (rear end operation part) 15b can be easily pushed.

Incidentally, as shown in FIG. 3, the binding band 51 has a frame-shaped lock portion (lock mechanism) 53 into which the flexible band portion 52 can be inserted, and is integrated with the base end (one end) side of the band portion 52. Molded.
An engagement tooth (continuous groove) 52a having a sawtooth cross section is formed on one surface side of the band portion 52, and meshes with the engagement teeth 52a of the band portion 52 while being elastically deformed in the frame shape of the lock portion 53. The meshing claw 53a is integrally formed.

That is, the binding band 51 is configured such that the meshing claw 53a of the lock part 53 that meshes with the meshing tooth 52a of the band part 52 restricts the movement of the band part 52 in the return direction and locks.
The lock portion 53 is also integrally formed with a release claw (pick portion) 54 that extends outward from the meshing claw 53a and faces the band portion 52 with a gap therebetween. The lock portion 53 meshes the meshing claw 53a by elastically deforming the release claw 54 so as to move together with the meshing claw 53a by moving the release claw 54 in the direction of approaching the band portion 52, for example. The band portion 52 is released from the meshed state with the teeth 52a to be released (allowed).
Accordingly, the binding band 51 shown in FIG. 3 is pulled out through the lock portion 53 while being engaged with the electric wire (target object) D in which the band portion 52 is bundled, and the engagement claw 53a is engaged with the engagement teeth 52a. Therefore, the movement of the band portion 52 in the returning direction can be restricted and the wire D can be locked so as to maintain the bundled state.

On the other hand, the unlocking tool 10 is inserted in the vicinity of the binding portion of the electric wire D by the binding band 51, and the locking portion 53 is released between the fixing protrusion 21 of the outer cylinder 11 and the sliding protrusion 25 of the inner cylinder 15. The nail | claw 54 and the band part 52 can be made easy in the state located together.
Thereafter, the unlocking tool 10 is directly hooked on the annular hooking portion 14 of the outer cylinder 11 and pushes the rear end portion 15b of the inner cylinder 15 against the urging force of the spring 19 like a syringe. The slide protrusion 25 can be slid in the direction in which the fixed protrusion 21 approaches the fixed protrusion 21.
By this operation, the unlocking tool 10 can release the locked state by holding the release pawl 54 and the band portion 52 of the lock portion 53 together between the fixed projection 21 and the slide projection 25. The lock part 53 can be pulled out.

At this time, the binding band 51 is in a state in which the release claw 54 of the lock portion 53 and the band portion 52 overlap each other in the direction orthogonal to the extending direction of the electric wire D that is wound around the band portion 52.
From this, the unlocking tool 10 can, for example, have a wide working space in front of the wiring box without approaching the binding portion of the electric wire D in the wiring box by the binding band 51 from the side like radio pliers. Therefore, the release claw 54 and the band portion 52 of the lock portion 53 can be easily positioned between the fixed projection 21 and the slide projection 25.
Further, the lock release tool 10 can easily release the lock state of the lock portion 53 by simply pushing the rear end portion 15b using the circular hook portion 14.
As a result, the binding band 51 can be recovered by simply pulling the band portion 52 out of the lock portion 53.

Here, in the present embodiment, the case where the inner cylinder is accommodated in the outer cylinder and the fixing member and the slide member are assembled will be described as an example. Needless to say, the sliding protrusions may be relatively slidably combined, and the fixing protrusion and the sliding protrusion may be provided respectively.
Further, by exposing the front end portion of the inner cylinder from the front end portion of the outer cylinder and pulling out the inner cylinder, the distance between the fixed protrusion and the slide protrusion can be narrowed and the pick section and the band section can be picked. You may do it.
