Description

  The present invention relates to a binding tool that can reduce the possibility that a long member that can be bundled is bundled in the axial direction of the long member.

  Bundling wire harnesses and other wire materials is widely performed. Not only wires, but long members are often bundled.

  One of the most well-known items for bundling long members is a string. When a long member is bundled using a string, the string can be freely moved in the axial direction of the long member unless the string is tied tightly.

  In order to solve this problem, Patent Documents 1 to 5 disclose a binding tool described below. The binding tool includes a band and a cylindrical portion. The cylindrical portion is provided at one end of the band. A hole is provided in the cylindrical portion. A claw is provided on the inner peripheral surface of the hole. The band passes through the hole in the cylindrical portion. The nail engages with the teeth on the band surface. When the teeth on the surface of the band and the claws engage with each other, the band cannot be removed from the hole in the cylindrical portion. Protrusions are provided on the surface of the band that is the inner peripheral surface when long members are bundled. The projection is pressed against the surface of the long member when the binding tool bundles the long member. Thereby, the binding tool is difficult to move due to the frictional force between the surface of the long member and the protrusion. For this reason, it is possible to bundle long members so that the binding tool does not move without applying the effort to bind the string as tightly.

  However, the inventions disclosed in Patent Literature 1 to Patent Literature 5 have room for improvement in reducing the possibility that the binding tool moves.

  An object of the present invention is to provide a binding tool that can reduce the possibility of shifting a long member that can be bundled with a wire rod in the axial direction of the long member.

  In order to achieve the above object, according to an aspect of the present invention, the binding tool 20 includes a band portion 30 and a buckle portion 34. The band part 30 has a band-like part 70 and a serration 74. The serration 74 is provided in the belt-like portion 70. The buckle part 34 is provided at one end of the band part 30. The buckle part 34 has a band through hole 40. The other end of the band portion 30 passes through the band through hole 40. A band removal claw 42 is provided on the inner peripheral surface of the band through hole 40. The band pull-out pawl 42 prevents the band portion 30 that has once passed through the band through hole 40 from coming out of the band through hole 40 by engaging with the serration 74. The band part 30 further includes a side wall part 72. The side wall part 72 is provided on the belt-like part 70 along the serration 74. The side wall portion 72 is provided in a section from the end of the serration 74 to the buckle portion 34 on the other end side of the band portion 30. The height of the side wall portion 72 from the belt-like portion 70 is lower than the height of the serration 74 from the belt-like portion 70.

  When the wire member or other long member 100 that can be bundled is bundled by the bundling tool 20, a portion of the serration 74 close to the other end of the band portion 30 engages with the band retaining claw 42. A portion of the serration 74 on one end side of the band portion 30 with respect to the portion engaging with the band removal preventing claw 42 bites between the long member 100 and the surface thereof. That is, the serration 74 has a function of preventing the buckle 34 from coming off and a function of preventing the skidding of the binding tool 20. At this time, the side wall portion 72 is provided in a section from the end of the serration 74 to the buckle portion 34 on the other end side of the band portion 30. Moreover, the side wall portion 72 is provided on the belt-like portion 70 along the serration 74. That is, when many long members 100 are bundled by the binding tool 20, the side wall portion 72 surrounds the bundle of long members 100. There is no section in which the side wall 72 does not surround the long bundle of members 100. For this reason, compared with the case where there is a section in which the side wall portion 72 does not surround the bundle of the long members 100, the mechanical strength of the band portion 30 is increased. Since the mechanical strength is increased, it is possible to tighten the band portion 30 with a stronger force than when there is a section where the side wall portion 72 does not surround the bundle of the long members 100. In addition, the height of the side wall portion 72 from the strip portion 70 is lower than the height of the serration 74 from the strip portion 70. Therefore, the side wall portion 72 does not prevent the serration 74 from biting into and between the long members 100. Since the side wall 72 is not obstructed, the serration 74 can sufficiently penetrate between the long member 100 and the surface thereof. As a result, the possibility that the binding tool 20 moves in the axial direction of the long member 100 described above can be reduced.

  In addition, it is desirable that the above-described side wall 72 is disposed so that there is a gap between the serration 74 and the side wall 72.

  When the bundle of the long members 100 described above is bundled by the band portion 30, a portion corresponding to the tip of the side wall portion 72 as viewed from the base with the band-shaped portion 70 is compressed. If there is a gap between the side wall portion 72 and the serration 74, the side wall portion 72 and the serration 74 are integrated when the portion of the side wall portion 72 corresponding to the tip as viewed from the base of the band-like portion 70 is compressed. Compared to the case, the portion corresponding to the tip is easily bent. Since the portion corresponding to the tip is easily bent, the portion corresponding to the tip is less likely to interfere with the biting of the serration 74 as compared with the case where the side wall portion 72 and the serration 74 are integrated. As a result, compared with the case where the side wall part 72 and the serration 74 are integrated, when the long member 100 mentioned above is bundled, possibility that the binding tool 20 will shift | deviate to the axial direction of the long member 100 can be made low.

  ADVANTAGE OF THE INVENTION According to this invention, when a long member which can be bundled with a wire rod and the like is bundled, the possibility of shifting in the axial direction of the long member can be reduced.

It is a perspective view of the binding tool concerning one Example of this invention. It is sectional drawing of the band part concerning one Example of this invention. It is sectional drawing of the buckle part vicinity concerning one Example of this invention. It is sectional drawing when the binding tool concerning one Example of this invention bundles an electric wire.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[Composition of binding tool]
FIG. 1 is a perspective view of a tying member 20 according to the present embodiment. FIG. 2 is a cross-sectional view of the band portion 30 according to the present embodiment. With reference to FIG. 1 and FIG. 2, the configuration of the binding tool 20 according to the present embodiment will be described.

  The binding tool 20 according to the present embodiment includes a band part 30 and a buckle part 34. The band part 30 is for bundling wires and other long members. The buckle part 34 is provided at one end of the band part 30. When the band unit 30 bundles the long members described above, the other end of the band unit 30, that is, the tip of the band unit 30 penetrates the buckle unit 34. In the case of the present embodiment, the band portion 30 and the buckle portion 34 are integrated. The binding tool 20 according to the present embodiment is made of resin.

[Band configuration]
The band part 30 according to the present embodiment includes a belt-like part 70, a side wall part 72, and a serration 74. The belt-like portion 70 is tightened when the long members described above are bundled. Thereby, the strip | belt-shaped part 70 clamp | tightens the long member. As shown in FIGS. 1 and 2, the side wall 72 is provided on the belt-like portion 70 along the serration 74. Further, as shown in FIG. 1, the side wall portion 72 is provided in a section from the end of the serration 74 to the buckle portion 34 on the other end side of the band portion 30. The side wall part 72 is integrated with the belt-like part 70. For this reason, the cross section of the band portion 30 has a “U” shape in katakana. A serration 74 is also provided in the belt-like portion 70. In this embodiment, “serration” means a line in which teeth are arranged. Each tooth constituting the serration 74 meshes with each tooth constituting the tooth mold portion 50 described later. As is apparent from FIG. 2, the serration 74 is higher than the side wall portion 72. That is, the height of the side wall portion 72 from the belt-like portion 70 is lower than the height from the tooth belt-like portion 70 constituting the serration 74.

[Buckle configuration]
FIG. 3 is a cross-sectional view of the vicinity of the buckle portion 34 according to the present embodiment. The configuration of the buckle portion 34 according to the present embodiment will be described with reference to FIGS. 1 and 3 described above. The buckle portion 34 according to the present embodiment has a band through hole 40. A band removal claw 42 is provided on the inner peripheral surface of the band through hole 40. The band retaining claw 42 has a tooth mold portion 50. The tooth mold portion 50 is composed of a plurality of teeth. Each tooth constituting the serration 74 inserted into the band through hole 40 is engaged with each tooth constituting the tooth mold portion 50 and cannot be removed.

[How to use the binding tool]
Hereinafter, the usage method of the binding tool 20 concerning a present Example in the case of bundling many electric wires 100 is demonstrated.

  First, the band part 30 of the binding tool 20 is wound around the bundle of the electric wires 100. After the band part 30 is wound, the tip of the band part 30 is inserted into the band through hole 40 of the buckle part 34. When the tip of the band part 30 penetrates the band through-hole 40, each tooth constituting the tooth mold part 50 of the band retaining claw 42 meshes with each tooth constituting the serration 74. Thereby, the band part 30 cannot be removed from the band through hole 40.

  In this state, when the tip of the band part 30 is further pulled, the bundle of the electric wires 100 is gradually tightened. At this time, each tooth constituting the serration 74 bites between the wires 100 and the surface of the wire 100.

  When each tooth constituting the serration 74 bites between the wires 100 and the surface of the wire 100, the bundle of the wires 100 is firmly tightened by further pulling the tip of the band part 30. Then, the part which protrudes from the buckle part 34 among the band parts 30 is cut off. Thus, the binding by the binding tool 20 is completed.

[Effect of tying tool according to this embodiment]
FIG. 4 is a cross-sectional view of the binding tool 20 when the binding tool 20 according to the present embodiment bundles many electric wires 100. The effect of the tying member 20 according to the present embodiment will be described with reference to FIG. When a large number of electric wires 100 are tightened with the binding tool 20, among the teeth constituting the serration 74, those close to the tip of the band part 30 mesh with the teeth constituting the tooth mold part 50 of the band retaining claw 42. Of the teeth constituting the serration 74, those surrounding the electric wire 100 bite between the electric wires 100 and the surface of the electric wire 100. That is, the serration 74 has a function of preventing the buckle 34 from coming off and a function of preventing the skidding of the binding tool 20. At this time, the side wall portion 72 is provided in a section from the end of the serration 74 to the buckle portion 34 on the distal end side of the band portion 30. That is, when many electric wires 100 are bundled by the binding tool 20, the side wall portion 72 surrounds the bundle of electric wires 100. There is no section in which the side wall portion 72 does not surround the bundle of the electric wires 100. For this reason, compared with the case where there is a section in which the side wall portion 72 does not surround the bundle of the electric wires 100, the mechanical strength of the band portion 30 is increased. Since the mechanical strength is increased, it is possible to tighten the band portion 30 with a stronger force than when there is a section where the side wall portion 72 does not surround the bundle of the electric wires 100. In addition, the height of the side wall portion 72 from the strip portion 70 is lower than the height of the serration 74 from the strip portion 70. Therefore, the side wall portion 72 does not prevent the serration 74 from biting between the wires 100 and the surface thereof. Since the side wall portion 72 is not obstructed, the serration 74 can sufficiently penetrate between the wires 100 and the surface thereof. As a result, the possibility that the electric wire 100 moves in the axial direction can be reduced.

  Also, if there is a gap between the side wall part 72 and the serration 74, when the bundle of the electric wires 100 is bundled with the band part 30, compared to the case where there is no gap between the side wall part 72 and the serration 74 and integrated. A portion corresponding to the tip of the side wall portion 72 is easily bent. Since the portion corresponding to the tip is easily bent, the portion corresponding to the tip is difficult to prevent the serration 74 from biting.

  In addition, the Example disclosed this time is an illustration in all the points. The scope of the present invention is not limited based on the above-described embodiments, and it is needless to say that various design changes may be made without departing from the spirit of the present invention.

  For example, the binding tool 20 is not limited to one made of resin. The binding tool 20 may be one in which each part constituting the binding tool 20 is separately manufactured and connected to each other.
