Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to the improvement of a binding tool that can easily bind wire rods such as harnesses wired inside an automobile, for example.

``Prior art'' As a conventional binding device of this type, for example, U.S. Patent No.
There is one shown in Publication No. 3543354.

The conventional binding device is an integrally molded product of synthetic resin.
As shown in FIGS. 3A and 3B, there is an annular holding part 1 that holds a wire, a pair of neck parts 2, 2 connected to both end edges of the annular holding part 1, and a pair of neck parts 2, 2 provided at the tip edge of each neck part 2. It consists of a pair of spherical enlarged heads 3, 3.

Further, as shown in the figure, the annular holding part 1 and the neck part 2 are integrally molded to have the same thickness, and the pair of neck parts 2, 2 contact each other with an inwardly curved state. molded into a state.

In actual use, as shown by the imaginary line in FIG. 3A, the pair of spherical enlarged heads 3, 3

is inserted into the annular holding part 1, each neck part 2 is deformed, and the pair of enlarged heads 3, 3 are twisted in the direction of the arrow shown in FIG. By intertwining the wire rods W, as shown in Fig. 4,
It is something that binds together.

"Problems to be solved by the invention" However, in the case of the conventional binding tool, the pair of neck parts 2, 2 connected to both end edges of the annular holding part 1,
Since the wire rods W are pre-molded to be in contact with each other, when inserting the wire W into the annular holding part 1, it is necessary to grasp the pair of enlarged heads 3 with both hands and expand each neck part 2 outward. Because of this requirement, there was a dislike that the work of inserting the wire W into the holding portion 1 would become unnecessarily complicated.

In addition, in order to obtain a complete binding state of the wire rod W, the enlarged head 3 provided at the tip edge of each neck 2,
Not only do you have to directly twist the wires 3 and 3 to intertwine them, but when you unbind the wire W, you have to untangle the enlarged heads 3 and 3 again, and then twist them together again. Since the necks 2, 2 have to be expanded outward, workability has been a major problem when it comes to binding and untying these wire rods W.

Furthermore, in the case of the conventional binding device, since the wire rod W is bound within the annular holding part 1 only by the intertwining of the pair of enlarged heads 3, 3, the binding state naturally becomes unstable. I couldn't deny it.

"Means for Solving the Problems" Therefore, the present invention was developed to effectively solve the problems of the conventional binding tools, and includes a ring-shaped holding part for holding the wire, and a ring-shaped holding part for holding the wire rod, A predetermined portion of the annular holding portion is made thicker based on a binding tool consisting of a pair of necks connected to both end edges of the holding portion and a pair of enlarged heads provided at the tip edge of each neck. While forming, a pair of necks connected to both end edges of the thick annular holding part are formed in advance so as to be spaced apart to define a wire insertion space, and the outer peripheral surfaces of each neck are engaged with each other. A configuration was adopted in which a matching locking portion is formed respectively.

"Operation" Accordingly, in the present invention, since the insertion space for the wire rod is defined in advance between the pair of neck parts, the wire rod can be inserted into the annular holding part by using the space as it is. As a result, the work of inserting the wire into the holding part becomes extremely simple, and after inserting the wire into the annular holding part, by pressing the appropriate places on both sides of the thick annular holding part inward against its elasticity, the pair of wires can be separated. The necks of the two necks also approach each other inwardly, and their enlarged heads automatically intertwine, and at the same time, the locking parts formed on the outer peripheral surfaces of the pair of necks engage with each other, so that the wire is held in an annular shape. This will ensure a strong bond within the department.

Also, if it becomes necessary to untie the wire rods, simply press the thick annular holding part inward at appropriate places on both sides to untangle the enlarged heads, and the pair of necks can be untied. automatically return to their original apart state and immediately define a space between the necks,
This makes it possible to easily untie the wire and also to easily remove the wire from the annular holding part.

``Example'' Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.The binding tool according to the example is also an integrally molded product of synthetic resin, and as shown in FIG. 1, it holds a wire rod. an annular holding part 11; a pair of neck parts 12, 12 integrally connected from both end edges of the annular holding part 11;
It consists of a pair of spherical enlarged heads 13, 13 that are integrally provided on the tip edge of each neck 12, and its feature lies in the following configuration.

That is, in this embodiment, as shown in the figure, the portions extending from the center of the annular holding portion 11 to both sides are:
The annular holding part 11 itself is formed to be thicker than the neck part 12 so as to actively impart elasticity to the neck part 12. The neck portions 12, 12 are formed in advance in a manner that they are spaced apart to define a wire insertion space 14, and a locking portion 15 having a shape such as an abacus bead that can be engaged with each other is provided on the outer peripheral surface of each neck portion 12. We adopted a configuration in which each was formed in succession.

Therefore, when binding the wire rods W using a binding tool having such a configuration, in this embodiment, since the insertion space 14 for the wire rod is defined in advance between the pair of neck parts 12, 12, Utilizing the space 14 as it is,
As a result of being able to insert the wire W into the annular holding part 11, the work of inserting the wire W into the holding part 11 is greatly simplified.

After inserting the wire W into the annular holding part 11, by pressing the thick annular holding part 11 at appropriate positions on both sides inward against its elasticity, the pair of neck parts 12,
12 also approach each other inwardly, and as shown in FIG. Since they are engaged, the wire rod W is thereby reliably and firmly bound within the annular holding portion 11.

In addition, when it becomes necessary to untie the wire rod W, press the thick annular holding part 11 at appropriate places on both sides inward in the same way to untangle the enlarged heads 13, 13. Due to the elasticity of the annular holding portion 11, the pair of neck portions 12, 12 automatically return to their original shape of being separated, and both neck portions 12, 1
Since the space 14 is defined between the two, this makes it possible to easily untie the wire rod W and to easily remove the wire rod W from the annular holding part 11.

Therefore, in this embodiment, the work of bundling and unbundling of the wire rods W can be done extremely easily with only one hand.

"Effect of the invention" As described above, the present invention forms a predetermined portion of the annular holding part thickly, and at the same time, a pair of neck parts connected to both end edges of the thick annular holding part are inserted into the wire in advance. In addition to forming them apart to define a space,
Since the locking portions that engage with each other are formed on the outer circumferential surface of each neck portion, not only the work of inserting the wire into the annular holding portion is greatly facilitated, but also the work of binding and unbinding the wire is made easier. can be easily done with just one hand, so compared to conventional tying tools,
This will greatly contribute to improving work efficiency.

Furthermore, locking portions that engage with each other are formed on the outer peripheral surfaces of the pair of necks, and when the wire rods are in a bundled state, not only the pair of enlarged heads but also these locking portions engage with each other. Therefore, it is possible to ensure that the wire rods are always bound in a reliable and strong manner.
