Description

[Technical Field]

[0001] The present invention relates to a binding device that surrounds and holds an object to be held. [Background technology]

[0002] Conventionally, a binding tool for holding a wire as a held object has been the binding band disclosed in Patent Document 1, for example. As shown in Fig. 13, this binding band 11 includes a band-shaped tail portion 12 and a holding portion 13 connected to the base end of the tail portion 12. Here, holding portion 13 is provided with an insertion hole 13a into which tail portion 12 is inserted from the tip end, and insertion hole 13a is provided with a ratchet 13b. Tail portion 12 is provided with a toothed rack 12a that engages with ratchet 13b and a V-groove 12b to provide flexibility. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 61-119952 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the tail portion 12 of the conventional cable tie 11 has an area where the rack 12a is provided and an area where the V-groove 12b is provided overlapping, and when the portion that has become bent in the V-groove 12b weakens and deteriorates over time, there is a risk that it will become difficult to continuously maintain the hold of the wire (object to be held).

[0005] The present invention has been made to solve the above-mentioned drawbacks of the conventional art, and its object is to provide a binding device that can continuously maintain the holding of the object to be held. [Means for solving the problem]

[0006] In order to achieve the above object, the binder according to the present invention has the following configuration: The fastener according to claim 1 is a fastener that surrounds and holds an object to be held. This fastener includes a band-shaped portion that is flexible in at least a portion of its longitudinal direction and surrounds the object to be held, and a fastening portion connected to the base end of the band-shaped portion. Here, the fastening portion has an insertion path through which the band-shaped portion is inserted from its tip and passes, and an engaging portion that engages with the inserted band-shaped portion and restricts movement of the band-shaped portion in a counter-insertion direction opposite to the insertion direction. The band-shaped portion also includes an engaging region in which multiple engaged portions that engage with the engaging portions are arranged in a line in the longitudinal direction of the band-shaped portion, and a shape-changing region located closer to the tip of the band-shaped portion than the engaging region, in which multiple grooves extending in a direction perpendicular to the longitudinal direction are arranged at intervals in the longitudinal direction, and in which a bending habit can be formed at the groove portions.

[0007] According to this fastener, the band-shaped portion includes an engagement region where engaged portions that engage with engagement portions provided on the fastening portion are arranged, and a shape-changing region where grooves are arranged. Therefore, by forming a bend in the grooves to change the shape of the band-shaped portion in the shape-changing region so that the tip of the band-shaped portion approaches the fastening portion, the band-shaped portion can be more easily inserted into the insertion path provided on the fastening portion. Furthermore, the shape-changing region is located closer to the tip of the band-shaped portion than the engagement region. Therefore, after this fastener surrounds and holds an object to be held, the shape-changing region exits the insertion path of the fastening portion and is in a position unrelated to holding the object. Therefore, deterioration over time of the grooves, which have become weakened by the bend, does not affect the holding of the object.

[0008] A binder according to a second aspect of the present invention is the binder according to the first aspect, wherein the band-shaped portion is formed in a linear shape. [Effects of the Invention]

[0009] According to the binding device of this invention, the shape-changing region in which the grooves are lined up is located closer to the tip of the band-shaped portion than the engaging region in which the engaged portions are lined up, so that deterioration over time of the groove portions that have become weakened due to bending does not affect the holding of the held object, and the holding of the held object can be continuously maintained.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0012] 1 to 12 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a binder that surrounds and holds an object to be held (not shown).

[0013] This fastener 1 comprises a band-shaped portion 2 that is flexible in at least a portion of the longitudinal direction 2a (over the entire length in the illustrated embodiment) and surrounds an object to be held, and a fastening portion 3 connected to the base end of the band-shaped portion 2. The fastening portion 3 has an insertion path 3a through which the band-shaped portion 2 is inserted from its tip 2b, and an engaging portion 3b that engages with the inserted band-shaped portion 2 and restricts movement in a counter-insertion direction 4b that is opposite to the insertion direction 4a in which the band-shaped portion 2 is inserted. The band-shaped portion 2 comprises an engaging region 2x and a shape-changing region 2y that is located closer to the tip of the band-shaped portion 2 than the engaging region 2x. Here, the engaging region 2x has multiple engaged portions 2c that engage with the engaging portions 3b of the fastening portion 3, lined up in the longitudinal direction 2a of the band-shaped portion 2. In the shape-changing region 2y, a plurality of grooves 2e extending in a direction 2d (horizontal direction) perpendicular to the longitudinal direction 2a of the band-shaped portion 2 are provided at intervals in the longitudinal direction 2a of the band-shaped portion 2, and in this shape-changing region 2y, the band-shaped portion 2 can be given a bending habit at the grooves 2e.

[0014] More specifically, the strip portion 2 is formed in a straight line before being bent at the groove portion 2e.

[0015] Specifically, the object to be held (not shown) is made up of long materials such as wiring or piping, and multiple pieces of these can be bundled together by wrapping the binder 1 (more specifically, the strip-shaped portion 2) around them, or the long materials can be fastened to a fixing portion (not shown) by wrapping the binder 1 around the fixing portion together with the long materials. However, the object to be held is not limited to long materials, and can be anything that can be wrapped around the binder 1.

[0016] The closure 1 is made of synthetic resin and is integrally formed from the synthetic resin. However, the closure 1 may be made partially or entirely of other materials such as fiber or metal, or may be formed by combining multiple components. Here, as described above, the band-shaped portion 2 has an engaging region 2x and a shape-changing region 2y, and in the illustrated embodiment, these engaging region 2x and shape-changing region 2y constitute the entire longitudinal direction 2a of the band-shaped portion 2. In the engaging region 2x, multiple engaged portions 2c, 2c are provided on the inner surface of the band-shaped portion 2 (the surface that becomes the inner side when surrounding the object to be held), and these engaged portions 2c, 2c are formed in a sawtooth shape. Furthermore, the engaging region 2x is provided with a reinforcing rib 2f extending in the longitudinal direction 2a of the band-shaped portion 2. Specifically, the reinforcing ribs 2f are provided on both sides of the width direction of the band-shaped portion 2 (that is, the direction 2d perpendicular to the longitudinal direction 2a of the band-shaped portion 2) and are positioned so as to sandwich the engaged portions 2c, 2c.

[0017] In the shape-changing region 2y, the grooves 2e are provided on the inner surface of the band-shaped portion 2, and each groove 2e has a substantially V-shaped cross section. Figures 6 and 7 show the state in which the shape of the band-shaped portion 2 in the shape-changing region 2y has been changed to an arc shape by creating a bend at each groove 2e, and Figure 8 shows the process of changing to an arc shape. Figures 9 and 10 show the state in which two grooves 2e are selected in the shape-changing region 2y and created a right-angle bend at those grooves 2e to change the shape of the band-shaped portion 2 in the shape-changing region 2y into a hook shape.

[0018] The fastening portion 3 is formed in a substantially rectangular parallelepiped shape. One surface 3c of this fastening portion 3 is provided so as to be flush with the inner surface of the band-shaped portion 2. The insertion path 3a is provided so as to penetrate the fastening portion 3 in the thickness direction of the base end portion of the band-shaped portion 2, and an entrance 3d of this insertion path 3a, through which the band-shaped portion 2 is inserted, is provided on the one surface 3c side. The engaging portion 3b is provided within this insertion path 3a. In the illustrated embodiment, a protruding portion 3e, having a tip portion deeper than the entrance 3d of the insertion path 3a, protrudes from the side of the insertion path 3a where the band-shaped portion 2 is located, and the engaging portion 3b is formed at the tip portion of this protruding portion 3e.

[0019] Next, the effects of the fastener 1 having the above configuration will be described. According to this fastener 1, the band-shaped portion 2 has an engaging region 2x where engaged portions 2c that engage with engaging portions 3b provided on the fastening portion 3 are lined up, and a shape-changing region 2y where grooves 2e are lined up. Therefore, by forming a bend at the grooves 2e and changing the shape of the band-shaped portion 2 in the shape-changing region 2y so that the tip 2b of the band-shaped portion 2 approaches the fastening portion 3 (more specifically, the entrance 3d of the insertion path 3a), the band-shaped portion 2 can be easily inserted into the insertion path 3a provided on the fastening portion 3. Furthermore, the shape-changing region 2y is located closer to the tip of the band-shaped portion 2 than the engaging region 2x. Therefore, after this fastener 1 surrounds and holds the object to be held, the shape-changing region 2y emerges from the insertion path 3a of the fastening portion 3 and is in a position unrelated to holding the object to be held. Therefore, deterioration over time of the grooves 2e, which have weakened due to the bend, does not affect the holding of the object to be held. In other words, by positioning the shape-changing region 2y where the groove portions 2e, 2e are lined up closer to the tip of the band-shaped portion 2 than the engaging region 2x where the engaged portions 2c, 2c are lined up, deterioration over time of the groove portions 2e that have become weakened due to bending does not affect the holding of the object to be held, and the holding of the object to be held can be continuously maintained.

[0020] Furthermore, the belt-like portion 2 is formed in a straight line, and the binder 1 can be easily manufactured by resin molding (more specifically, injection molding). Furthermore, by subsequently forming a bend at the groove portion 2e of the shape-changing region 2y, the changed shape of the belt-like portion 2 can be maintained.

[0021] The present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, the entire longitudinal direction 2a of the band-shaped portion 2 is made up of the engaging region 2x and the shape-changing region 2y, but there may be a region between the engaging region 2x and the shape-changing region 2y that does not have the engaged portion 2c or the groove 2e, or there may be a region on the base end side of the band-shaped portion 2 that does not have the engaged portion 2c, or there may be a region on the tip end side of the band-shaped portion 2 that does not have the groove 2e.

[0022] The strip portion 2 does not have to be flexible over the entire length in the longitudinal direction 2a, and may have a portion that is not flexible.

[0023] Furthermore, the shapes of the engaged portion 2c and the groove portion 2e are not limited to the shapes shown in the figure. For example, the cross section of the groove portion 2e is not limited to being approximately V-shaped, and the cross section may be arc-shaped or concave, etc. [Explanation of symbols]
