Description

[Technical field]

[0001] The present invention relates to a cable tie for fixing or bundling objects to be tied together, and more particularly to a cable tie for fixing nets or the like to posts or fences when constructing a structure. [Background technology]

[0002] Conventionally, cable ties have been known that are made up of a head portion, a band portion, and a tail portion, and are entirely molded from synthetic resin such as nylon, fluororesin, or polyolefin. The tail portion is inserted into the head portion, and a locking piece provided on the head portion is engaged with a serrated portion formed on the surface of the band portion, thereby locking the cable ties. However, in order to provide the locking piece on the head portion, the head portion is formed in a three-dimensional box shape (Patent Document 1, Figure 1). This makes the cable ties bulky when transporting them, and makes them difficult to use in small spaces.

[0004] An object of the present invention is to provide a cable tie that is easy to transport and use. [Means for solving the problem]

[0005] In the present invention, sawtooth portions are provided on both side edges of the band portion, not on the surface of the band portion, and through holes are provided in the head portion. Using a specific sheet That is, the present invention provides a binding band in which a head portion, a band portion, and a tail portion are made of the same sheet, and both side edges of the band portion are formed with sawtooth portions, and the head portion is provided with a through hole through which the tail portion and the band portion can be inserted. The sheet is a woven fabric having warp yarns and weft yarns as constituent yarns, the constituent yarns being multifilament yarns made of a core-sheath type composite filament consisting of a core component and a sheath component having a melting point lower than that of the core component, the constituent yarns are fused to each other by melting and solidifying the sheath component, and the core component having a fibrous form is present in a matrix consisting of the melted and solidified sheath component. This is about cable ties. Effect of the Invention

[0006] The cable tie according to the present invention has a head portion, a band portion, and a tail portion which are integral with each other. Specific The cable tie is made of a sheet. The tail and band are inserted into the through hole of the head, and the sawtooth portions formed on both sides of the band engage with the periphery of the through hole, thereby fixing or bundling the objects to be tied together. This eliminates the need for a three-dimensional box-shaped head, and provides the advantage of making the cable tie easier and more streamlined to transport and use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The cable tie according to the present invention comprises a head portion 1, a band portion 2, and a tail portion 3. The head portion 1, the band portion 2, and the tail portion 3 are a single, planar sheet. Any rigid material may be used to compose this sheet, and may be synthetic resin, metal, or fabric.

[0009] In the present invention, the material of the sheet is preferably made of fabric. If the material is made of metal, there is a risk that the sawtooth portions 4, 4, 4... provided on both side edges of the band portion 2 may injure the body during work, but if the material is fabric, the risk of injury is reduced. Fabric is generally flexible, but it can be made rigid by fusing and integrating the threads that make up the fabric. However, there is less risk of injury to the body compared to a metal material. As the fabric, woven fabric, knitted fabric, nonwoven fabric, etc. are used.

[0010] The following will explain the process using a woven fabric as an example. First, a multifilament yarn made of a core-sheath type composite filament is prepared as the warp and weft. The core-sheath type composite filament is made of a core component and a sheath component having a melting point lower than that of the core component. Examples of the core component / sheath component combination include polyethylene terephthalate / copolymer polyester, polyethylene terephthalate / polyethylene, polyethylene terephthalate / polypropylene, polypropylene / polyethylene, or nylon 66 / nylon 6. In particular, the combination of polyethylene terephthalate / copolymer polyester is preferable. This is because it has excellent weather resistance and is suitable for using the cable tie according to the present invention outdoors. After weaving a fabric using this multifilament yarn as the warp and weft, the fabric is thermally processed at a temperature at which only the sheath component softens or melts. This thermal processing results in a sheet in which the sheath components are fused and integrated. This sheet is a fabric in which the core component having a fibrous form is present as a woven fabric in a matrix made of the sheath component.

[0011] The cable tie according to the present invention can be obtained by punching a sheet made of a rigid material such as a fabric. That is, the head portion 1, the band portion 2, and the tail portion 3 are formed by punching, and sawtooth portions 4, 4, 4... are formed on both side edges of the band portion 2, and a through hole 5 is formed in the head 1. The number of sawtooth portions 4 is arbitrary as shown in Figs. 1 and 2, and several to several tens of them can be formed. The shape of the through hole 5 is also arbitrary as long as the tail portion 3 can be inserted therein. For example, a triangle, a square, an ellipse, or the like is used. In the present invention, a triangle is preferable. The dimensions of each portion of the cable tie shown in Figs. 1 and 2 are as shown in Figs. 4 and 5.

[0012] The method of using the cable tie according to the present invention is as follows. First, the tail portion 3 is held with the fingers, the cable tie is aligned with the object to be tied, and then the tail portion 3 is twisted and inserted into the through hole 5. Then, the band portion 2 is also inserted into the through hole 5 until the object to be tied is fixed or bundled. After that, the sawtooth portions 4, 4 on both sides of the band portion 2 are engaged with the periphery of the through hole 5. This engagement may be performed automatically when the fingers are released from the tail portion 3, as the twist returns to its original state due to the rigidity of the band portion 2. FIG. 3 is a photograph showing the state in which the sawtooth portions 4, 4 are engaged with the periphery of the through hole 5, although the object to be tied is not shown. When using the cable tie in a narrow space, as described in Patent Document 1, the tip of the tail portion 3 may be bent into a U-shape or L-shape and inserted into the narrow space.

[0013] The cable tie according to the present invention can be used for any purpose for fixing or bundling objects to be bound. For example, it can be used for conventionally known purposes such as attaching a net to a structural support or fence, connecting nets together, or bundling wires such as electric wires.
