Description

[Technical Field]

[0001] The present invention relates to a cable tie. [Background technology]

[0002] A plurality of thin, long, and bent members such as electric wires, tubes, and cables arranged in a processing device are bound together by binding bands.

[0003] A conventionally known cable tie 30 is shown in Figure 6. The illustrated cable tie 30 comprises a band body 31 having fine irregularities 32 formed on one surface 31a in a direction perpendicular to the longitudinal direction of the cable tie 30, and a fixing portion 33 formed at an end of the band body 31. An engagement claw (not shown) that moves only in one direction is disposed inside 33a of the fixing portion 33. When binding an object to be bound, such as a cable, the band body 31 is wrapped around the object to be bound, a tip 31c of the band body 31 is inserted into the inside 33a of the fixing portion 33, and the tip 31c is pulled in the direction indicated by arrow R0 to tighten the object to be bound. The irregularities 32 formed on one surface 31a of the band body 31 engage with the engagement claw, preventing the band body 31 from loosening (see, for example, Patent Document 1).

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-086503 Summary of the Invention [Problem to be solved by the invention]

[0005] In the conventional cable ties described above, since it is unknown how thick the object to be tied will be, the band body 31 is set to be relatively long. And, since only one fixing portion 33 is set for each cable tie, the band body 31 on the tip 31c side that extends outward from the fixing portion 33 of the cable tie 30 used for tying becomes unnecessary, and to avoid getting in the way of subsequent work, the band body 31 that extends outward from the fixing portion 33 is cut off and discarded.

[0006] As described above, the problem with the conventional cable tie 30 is that, although the band body 31 is set to be longer, in reality, only a portion of the band body 31 near the fixed portion 33 is used, and the remaining portion is discarded and wasted, which is uneconomical.

[0007] The present invention has been made in consideration of the above facts, and its main technical objective is to provide a cable tie that can solve the problem that with conventional cable ties, only a portion of the band body is used, and the remaining portion is cut off and discarded, resulting in waste, making it uneconomical. [Means for solving the problem]

[0008] In order to solve the above-mentioned main technical problem, according to the present invention, there is provided a cable tie comprising a band body, a convex portion formed on one surface along the longitudinal direction of the band body, a concave portion formed on the other surface along the longitudinal direction of the band body and engaging with the convex portion, a plurality of anti-reverse pieces formed on the outer surface of the convex portion, and a plurality of return pieces formed on the inner surface of the concave portion and engaging with the anti-reverse piece to prevent the band body from moving backward.

[0009] The binding band of the present invention is preferably configured to be cuttable to a required length, and is also preferably capable of being released from binding by separating the recessed portion from the protruding portion. [Effects of the Invention]

[0010] The cable tie of the present invention comprises a band body, a convex portion formed on one longitudinal surface of the band body, a concave portion formed on the other longitudinal surface of the band body that engages with the convex portion, a plurality of anti-reverse pieces formed on the outer surface of the convex portion, and a plurality of return pieces formed on the inner surface of the concave portion that engage with the anti-reverse pieces to prevent the band body from moving backward.Therefore, the remaining cable tie after being cut to the length required to tie the object to be tied does not become waste material but can be used as the next cable tie, making it economical.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a binding band configured based on the present invention will be described in detail with reference to the accompanying drawings.

[0013] Fig. 1 shows a cable tie 1 according to this embodiment. The cable tie 1 shown in the figure is made of a flexible synthetic resin selected from, for example, nylon, fluororesin, polypropylene, polyethylene, etc., but is not limited to these. The cable tie 1 shown in the figure is long, for example, 2 to 3 meters in length.

[0014] The binding band 1 shown in FIG. 1 includes a band body 10, one surface 1a (upper surface in the figure) along the longitudinal direction of the band body 10, and the other surface 1b (lower surface in the figure). A protrusion 12 extending along the longitudinal direction is formed on the one surface 1a. A recess 14 that engages with the protrusion 12 formed along the longitudinal direction is formed on the other surface 1b. The protrusion 12 is formed over the entire area from one end A to the other end B along the longitudinal direction of the one surface 1a. The recess 14 is also formed over the entire area from one end A to the other end B along the longitudinal direction of the other surface 1b, and is open to the other surface 1b.

[0015] The lower part of FIG. 1 shows an enlarged perspective view of one end A and the other end B of the illustrated binding band 1.

[0016] The protrusion 12 formed on one surface 1a of the band body 10 will be described in more detail with reference to FIG. 1 as well as FIG. 2(a) which shows a plan view of one end A of FIG.

[0017] The protrusion 12 stands upright on one surface 1a of the band body 10, positioned at the center in the width direction. As can be seen from the enlarged perspective view of one end A in FIG. 1, a constricted portion 12a that is narrower than the width of the front side of the protrusion 12 is formed at the connection between the protrusion 12 and one surface 1a of the band body 10. A plurality of backflow prevention pieces 13 are formed on the outer surface of the protrusion 12 at regular intervals in the longitudinal direction, on both sides of the protrusion 12 in the width direction. As can be seen from FIG. 2(a), the backflow prevention pieces 13 are shaped to be inclined from the other end B side toward the one end A side when viewed in a plan view. The tip 13a of the backflow prevention piece 13 is narrower than the base 13b connected to the protrusion 12 and is bent in a direction perpendicular to the longitudinal direction of the band body 10.

[0018] Next, the recess 14 formed on the other surface 1b of the band body 10 and engaging with the protrusion 12 will be described in more detail. FIG. 2(b) shows a cross-sectional view taken along the line XX in the enlarged perspective view of one end A in FIG. 1. As can be seen from FIG. 2(b), the inner surface of the recess 14 is formed with a plurality of barbs 15 with which the aforementioned backflow prevention pieces 13 engage. The barbs 15 are formed to correspond to the backflow prevention pieces 13 of the aforementioned protrusion 12, and the spacing between adjacent barbs 15 in the longitudinal direction of the binding band 1 corresponds to the spacing between the aforementioned backflow prevention pieces 13. The barbs 15 have an inclined surface 15a inclined from the other end B side toward the one end A side, and the inclination angle of the inclined surface 15a corresponds to the inclination angle of the base 13b of the aforementioned backflow prevention piece 13. Furthermore, two adjacent barbs 15 in the longitudinal direction of the band body 10 form a storage section 16 in which the backflow prevention piece 13 is stored. The inclined surface of the accommodation portion 16 on the other end B side is formed with a step portion 16a including a tapered surface.

[0019] The binding band 1 of this embodiment has roughly the configuration as described above, and the specific usage and effects of the binding band 1 will be described below.

[0020] As shown in FIG. 3, a long cable tie 1 can be bundled in a roll. As described above, the cable tie 1 of this embodiment is made of a flexible resin and can be easily cut with scissors, a cutter, or the like. To bundle a cable group C consisting of multiple cables as shown in FIG. 4(a), a cable tie 1' of the required length can be cut out from the cable tie 1. For example, if the circumference of the cable group C is 10 cm, the length of the cable tie 1' can be approximately 10 cm + 2 cm. When the cable tie 1' is cut out from the long cable tie 1, the cut side forms one end A shown in FIG. 1, and the tip side forms the other end B shown in FIG. 1.

[0021] Once the required length of cable tie 1' has been prepared by cutting it from the long cable tie 1 as described above, as shown in FIG. 4(a), the cable tie 1' is wrapped around the desired position of the cable group C. Next, as shown in FIG. 4(b), the recess 14 of one end A is positioned in front of the protrusion 12 of the other end B, the protrusion 12 is inserted into the recess 14, and the one end A is slid in the direction indicated by arrow R1. FIG. 5(a) shows the state of the protrusion 12 and the backflow prevention piece 13 inside the recess 14 (corresponding to the cross-sectional view taken along line XX in FIG. 2(b)) when insertion of the protrusion 12 into the recess 14 begins. The widthwise dimension inside the recess 14 is set larger than the widthwise dimension of the protrusion 12, and by inserting the protrusion 12 into the recess 14 and sliding one end A side in the direction indicated by the arrow R1, the backflow prevention piece 13 formed on the outer surface of the protrusion 12 inserted into the recess 14 as shown is bent inside the recess 14, and the protrusion 12 can be advanced inside the recess 14 in the direction indicated by the arrow R2 in the figure.

[0022] To bundle the cable group C, one end A is further slid in the direction indicated by arrow R1, thereby reaching a state in which the cable group C is bundled, as shown in Fig. 4(c). As a result, as shown in Fig. 5(b), the reverse movement prevention piece 13 disposed on the protrusion 12 is accommodated in the accommodation portion 16 formed by the barb 15 in the recess 14. This causes the reverse movement prevention piece 13 to engage with the barb 15, preventing the other end B of the cable tie 1' from moving backward within the recess 14, i.e., preventing the protrusion 12 from moving in the direction opposite to the direction indicated by arrow R2 in Fig. 5(a) in which the protrusion 12 was advanced during bundling, and preventing the cable tie 1' from loosening. Furthermore, a step portion 16a including a tapered surface as shown in the figure is formed on the inclined surface on the other end B side of the return piece 15 that constitutes the storage section 16, so that the reverse travel prevention piece 13 can be easily stored in the storage section 16, and when the cable tie 1' is further tightened while the reverse travel prevention piece 13 is stored in the storage section 16, the reverse travel prevention piece 13 can be easily pulled out of the storage section 16.

[0023] In the above-described embodiment, when the cable tie 1' is to be released from the cable group C, one end A of the cable tie 1' of this embodiment can be peeled off in the outward direction shown by arrow R3 in Figure 4(c), thereby separating the recess 14 on the side of one end A from the protrusion 12, thereby releasing the cable tie. This makes the cable tie 1' of this embodiment reusable and not wasted.

[0024] In the above embodiment, when bundling the cable group C, a cable tie 1' of a predetermined length was cut out from the cable tie 1 in advance and the bundling was performed. However, the present invention is not limited to cutting out a cable tie 1' of a predetermined length in advance. For example, the tip end of the long cable tie 1 shown on the left side of Figure 3 can be wrapped around the cable group C shown in Figure 4(a), and the convex portion 12 on the tip end side (the other end B side shown in Figure 1) can be inserted from the lower side of the recess 14 at the desired position of the cable tie 1, and the main body 10 of the cable tie 1 can be slid in the direction of bundling the cable group C, thereby engaging the anti-reverse piece 13 of the convex portion 12 with the return piece 15 formed on the inner surface of the recess 14 to perform temporary bundling. Then, a cable tie 1' of the required length can be cut out from the cable tie 1 in the range where the temporary bundling was performed.

[0025] As described above, the cable tie 1 of this embodiment does not require a fastening portion like cable ties in the prior art. It can be cut from any region of the cable tie 1 shown in FIG. 1 to any length and still function as a cable tie. Therefore, when the cable tie is cut to the required length for binding an object, the remaining cable tie does not become waste material and can be used as a cable tie to bind another object. This is economical, and there is no need to dispose of the waste material, eliminating the problem of it being difficult to endure. Furthermore, as described in the above embodiment, the binding can be easily released by separating the recessed portion 14 from the protruding portion 12, so the cable tie can be used repeatedly, which is economical.
