Description

Technical Field

[0001] The present invention relates to a connecting member for connecting binding bands to each other and a connecting structure for two binding bands using the same.

Background Art

[0002] There is known a binding band provided integrally with a band portion formed with protrusions having a cross-sectional saw blade shape and a lock portion for inserting and locking the band portion. In such a binding band, generally, a set of bindings is made by one binding band. However, for example, as shown in FIG. 12, there may be a case where a plurality of bindings are desired at both ends of the band portion. This example shows a usage method in which the other binding object is bound with a space from one of the bound binding objects and is suspended in the vertical direction shown in the figure.

[0003] Patent Document 1 describes a binding band in which two sets of band portions and heads are integrally formed and bundles of separate electric wires can be formed at both ends. Further, Patent Document 2 describes a binding band connecting member capable of connecting two binding bands binding separate wire harnesses. This binding band connecting member is one in which a plurality of band lock portions are connected by a flexible belt-shaped relay portion.

Patent Document 1

Patent Document 2

[0005] However, the cable tie described in Patent Document 1 has a binding mechanism at each end of a single cable tie. Therefore, even if you only want to replace the lower bound object as shown in Figure 12, it was necessary to re-bind both the upper and lower objects using a new cable tie. Furthermore, the connecting member described in Patent Document 2 has a strip-shaped intermediate section, and the insertion direction of the band is perpendicular to the intermediate section. Therefore, if used in a way that suspends it in the direction of gravity, as in the example shown in Figure 12, the connecting member may twist or the load may concentrate at the end of the intermediate section, making it prone to deterioration. [Overview of the project] [Problems that the invention aims to solve]

[0006] The object of the present invention is to solve the above-mentioned conventional problems and to provide a simple and robust connecting member that allows the connecting cable ties to be attached and detached independently, and a connecting structure for two cable ties using the same. [Means for solving the problem]

[0007] To solve the above problems, a cable tie connecting member is provided for connecting cable ties, each having a band portion extending in a strip shape and a locking portion integrally, wherein two insertion passages are formed inside a rectangular parallelepiped body, each having a locking portion for inserting and locking the band portion, the entrances to the insertion passages are opened on each of a pair of opposing surfaces of the body, and the exits to the insertion passages are opened on a surface parallel to the width surface of the band portion at the entrance.

[0008] Furthermore, it is preferable that the outlet of the insertion passage is configured to have one opening on each of a pair of opposing surfaces.

[0009] Furthermore, it is preferable that the insertion passage is configured to include a bent portion that bends at an obtuse angle. It is also preferable that the opening at the exit of the insertion passage is larger than the opening at the entrance.

[0010] Furthermore, the present invention relates to a connecting structure for two cable ties using the cable tie connecting member, wherein the band portion that binds the objects to be bound is inserted into the insertion passage and locked, and the excess length portion of at least one of the band portions is cut at the exit position, and the tip of the cut band portion is located inside the insertion passage. [Effects of the Invention]

[0011] The present invention makes it possible to provide a simple and robust connecting member that allows the connecting cable ties to be attached and detached independently, and a connecting structure for two cable ties using the same. [Brief explanation of the drawing]

Best Mode for Carrying Out the Invention

[0013] The following shows the best mode for carrying out the invention. As shown in FIG. 1, the binding band connecting member 10 of this embodiment has a rectangular parallelepiped main body 11 made of resin. The main body 11 includes a first width surface 12 and a second width surface 13 which are a pair of surfaces facing each other. In this specification, in FIG. 1, the left surface is referred to as the first width surface 12, and the surface facing the first width surface 12 is referred to as the second width surface 13.

[0014] As shown in FIG. 2, on the first width surface 12 of the embodiment, a first inlet 22 into which a band portion 41 of a known binding band 40 described later can be inserted is opened. The first inlet 22 is an inlet of a first insertion passage 21 formed inside the main body 11 and through which the band portion 41 can be inserted. The first inlet 22 is disposed at a position below the center in the vertical direction of the first width surface shown in FIG. 2. On the inner wall of the first insertion passage 21, a first locking portion 23 capable of locking the band portion is formed at a position near the first inlet 22. The first locking portion 23 of the embodiment is a locking claw capable of engaging with a serrated engaging groove formed in the band portion 41.

[0015] Also, as shown in FIG. 3, on the second width surface 13 as well, similar to the first width surface 12, a second inlet 32 which is an inlet of a second insertion passage 31 through which the band portion 41 can be inserted is opened, and a second locking portion 33 is provided at a position near the second inlet 32. The second inlet 32 is disposed at a position above the center in the vertical direction of the second width surface shown in FIG. 3.

[0016] In the main body 11, a pair of surfaces that are orthogonal to the first width surface 12 and the second width surface 13 and parallel to the width surface of the band portion 41 at the first inlet 22 and the second inlet 32 are defined as a first length surface 14 and a second length surface 15. In this specification, in FIG. 1, the upper surface is referred to as the first length surface 14, and the surface facing the first length surface 14 is referred to as the second length surface 15.

[0017] As shown in Figure 4, a first outlet 24, which is the exit for the first insertion passage 21, is opened on the first length surface 14. Also, as shown in Figure 5, a second outlet 34, which is the exit for the second insertion passage 31, is opened on the second length surface 15. It is also possible to configure the first outlet 24 and the second outlet 34 to open on the same surface. As shown in Figure 6, the first insertion passage 21 and the second insertion passage 31 each have bent portions 25 and 35 that bend at an obtuse angle at approximately the midpoint of their respective positions.

[0018] Furthermore, in this embodiment, as shown in Figure 6, since the opening area of ​​the first outlet 24 is larger than the opening area of ​​the first inlet 22, the distance from the first inlet 22 to the first outlet 24 within the first insertion passage 21 is longer on the inner wall 212 side than on the inner wall 211 side. As a result, as will be explained later, when the excess length of the band portion 41 is cut closer to the inner wall 211 side, the tip of the cut band portion 41 fits inside the first insertion passage 21 and does not protrude outside the cable tie connecting member 10, which is preferable. This configuration is also the same for the second insertion passage 31.

[0019] Next, a method for connecting cable ties using the cable tie connecting member 10 will be described. As shown in Figure 7, the example will be described using known cable ties 40, 40 and connecting them with the cable tie connecting member 10. The cable tie 40 has a band portion 41 that extends in a strip shape with a sawtooth-shaped engagement groove formed on one side, a locking portion 42 at one end, and a tapered tail portion 43 at the other end.

[0020] First, the band portion 41 of the cable tie 40 is wrapped around the object to be tied C, and the tail portion 43 is inserted through the lock portion 42 and pulled, thereby tightening and locking the loop formed by the band portion 41, and tying the object to be tied C. Next, the tip of the tail portion 43 of the cable tie 40 in this state is inserted into the first inlet 22. The tail portion 43 is advanced further in, and its tip is brought out through the first outlet 24. The tail portion 43 is pulled out further and stopped at a position where the distance between the lock portion 42 and the cable tie connecting member 10 is the desired length, at which point the first locking portion 23 and the band portion 41 engage and lock. The cable tie 40 is similarly inserted through the second insertion passage 31 on the opposite side and locked. In this way, as shown in Figures 7 and 8, the cable ties 40, 40 can be connected via the cable tie connecting member 10.

[0021] As shown in Figure 9, it is preferable to cut off any excess portion of the band 41 that protrudes outside the main body 11 at the exit point using a tool such as wire cutters. Leaving these excess portions as they are may cause them to get caught during installation or use. Furthermore, since the cut edges of the resin band 41 tend to be sharp, if even a small portion of the tip protrudes outside the main body 11 after the excess portion has been cut, there is a risk that workers or users may accidentally touch it and suffer injury.

[0022] In this embodiment, as shown in Figure 9, the insertion passages 21 and 31 are obtuse-angled V-shaped, bending at the bent portions 25 and 35. Furthermore, as mentioned above, since the opening area of ​​the outlets 24 and 34 is larger than the opening area of ​​the inlets 22 and 32, the effect is obtained in which the tip of the cut band portion 41 does not protrude outside the main body 11 but is more likely to fit inside the insertion passages 21 and 31. Specifically, for example, when cutting the excess length protruding from the first outlet 24, if the band portion 41 is held and brought towards the inner wall 211 side of the first insertion passage 21 before cutting, after cutting, the elasticity of the band portion 41 causes its tip to come into contact with the inner wall 212 on the opposite side. As a result, the tip of the cut band portion 41 retracts into the first insertion passage 21, preventing injury without the need to perform processing such as grinding or chamfering the cut edge.

[0023] The connecting structure of cable ties 40, 40 using the cable tie connecting member 10 of the present invention can be applied, for example, to attaching a child's handrail B2 to the lower part of an adult's handrail B1, as shown in Figure 10. In this example, only the lower cable tie 40 can be replaced as the child grows, improving work efficiency. Furthermore, even when used in a vertically suspended manner as in this example, the main body 11 is block-shaped, making it less likely for the main body 11 to deform under the load of the bound object. In addition, since the band portion 41 of the connected cable ties 40 is locked at an angle beyond the locking portions 23, 33, as shown in Figure 7, when suspended vertically, a load is applied to the locking portions 23, 33, and the engagement between the band portion 41 and the locking portions 23, 33 becomes stronger.

[0024] Therefore, according to the present invention, it is possible to provide a simple and robust cable tie connecting member 10 and a connecting structure for cable ties 40, 40 using the same, in which the connecting cable ties 40, 40 can be attached and detached independently, and deformation and deterioration of the main body 11 are less likely to occur even when used in a manner that involves hanging in the direction of gravity.

[0025] Furthermore, the cable tie connecting member 10 of the present invention is not limited to use for hanging in the direction of gravity, but can be used for a variety of other applications. For example, as shown in Figure 11, the connecting structure of the present invention can be used to connect a clipboard C that holds writing paper with a writing instrument W such as a pen. In this example, an insertion hole C1 is formed in the corner of the clipboard C, through which the cable tie 40 is passed and secured by the locking part 42. On the other hand, another cable tie 40 is also attached to the head of the writing instrument W, and the respective band parts 41 are connected by the cable tie connecting member 10. This prevents the loss of the writing instrument W and makes it easy to replace the writing instrument W.

[0026] Although the present invention has been described above with reference to the embodiments described, the present invention is not limited to the above embodiments and can be implemented in various forms. [Explanation of Symbols]
