DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a binding band,
More specifically, the present invention relates to a binding band that can be easily released after being bound once.

[0002]

2. Description of the Related Art When each device is connected by wiring,
In particular, when there is a considerable distance between each device, and these devices are connected by long wires, extending the long wires as they are is not only disturbing the whole but also unsightly, and may cause accidents. Therefore, an appropriate part in the wiring is bound by a binding band to eliminate slack. Since the binding band is made of resin, it is light and durable and easy to handle, so that it is frequently used.

One example is shown in FIG. As shown in FIG. 5 (a), the binding band A ′ has a head 1 and a foot 2
And a plurality of wirings B, etc., to be bound, are bundled, and the feet 2 are wound around these, and the tip 2a of the feet 2 is inserted into the gap 3 inside the head 1 so that the arrow T The binding object B is tightened and bound by moving in the direction of. In this case, one side of the foot 2 is
As shown in (b) in an enlarged manner, a plurality of convex portions 2b each having a single mountain shape are formed over the longitudinal direction thereof,
These convex portions 2b mesh with a plurality of concave portions 1b forming convex and concave portions having a single-valley shape on the upper surface of the ratchet portion 1a provided inside the head portion 1.

A concave portion 1b of the head portion 1 and a convex portion 2b of the foot portion 2
Is engaged in a ratchet type, and the foot 2 advances in the direction of the arrow T but does not advance in the reverse direction. Due to such a structure, the binding object B such as a plurality of wirings can be tightened in only one direction (fastening). Therefore, once the objects to be tied are fastened and tied with a tying band, the objects to be tied are not separated, and the tying band is made of a flexible resin. It is expensive.

[0005]

However, if it is desired to increase the number of objects to be tied or to change the object to be tied after fastening with the tying band, the tying of the tying band cannot be released. It was necessary to cut a part of the binding part of the binding band, prepare a new binding band, and repeat the binding again. The cut tie band cannot be reused from the start, and is in vain because it has to be waste.Moreover, such a situation often occurs at a construction site. Was causing an increase in things.

However, as a binding band capable of releasing the binding, a lever-shaped convex piece hanging down from the bottom of the head portion in parallel with the foot is provided, and when the binding is desired to be released, the convex piece is pressed. However, there is a type that can release the binding, but this does not allow the convex piece to be pinched by the finger, and furthermore, it must exert a force that strongly presses in the direction of the object to be bound. It is difficult to apply and it is not easy to release the unity. Further, since the ratchet portion has only one mesh, the binding force at the time of binding is weak, and the ratchet portion may be easily disengaged by the action of an excessive external force. In addition, the head portion has a complicated shape and is larger than the binding band shown in FIG. 5, and the foot portion connected to the head portion is wider. cost,
All of the manufacturing costs are high, making them extremely inconvenient and impractical.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a binding band that can be easily untied even after the binding object is once bound by the binding band, and that does not increase the manufacturing cost. Is to do.

[0008]

The above object is achieved by the invention described in each claim. That is, the characteristic structure of the binding band according to the present invention includes a head portion and a foot portion connected to the head portion, and the foot portion is wound around the object to be bound, and the gap portion formed in the head portion is formed. By being inserted into the gap, the ratchet portion provided with the concave and convex portions formed in the void portion and the convex and concave portions formed in the foot portion are meshed with each other, and are made of a resin that can bind the object to be bound. The tongue has a tongue extending from the ratchet portion of the head to the outside of the head, and the tongue is moved in a direction away from the foot inserted into the gap of the head to move the tongue. An object of the present invention is to make it possible to release the engagement between the ratchet portion and the foot portion.

With this structure, the tongue can be easily moved from the head by moving the tongue in the direction away from the inserted foot, or by simultaneously pulling the foot. The ratchet portion and the foot portion can be easily disengaged even if they are already bound. Therefore, even after the object to be tied has been tied, the tying can be released, so if you want to re-bind, you do not need to cut the tying band to prevent reuse as in the prior art. Does not increase costs. Moreover, since it is only necessary to provide a tongue piece in terms of structure, the binding force at the time of binding is not different from that of the related art, the structure is not complicated, and the manufacturing cost is not increased. As a result, it was possible to provide a binding band that can be easily released even after the object to be bound is once bound by the binding band, but does not increase the manufacturing cost.

[0010] It is preferable that the angle formed by the ratchet portion and the tongue piece extending therefrom is 120 ° or more. With this configuration, by inserting the tip of a tool, such as a screwdriver, into the gap between the foot and the tongue, the tongue can be forcibly pushed down, and the binding can be further released. It is convenient.

[0011] It is preferable that a convex and concave portion meshing with the ratchet portion is formed up to a tip portion of the foot portion.
In this case, even if the length is the same as that of the conventional binding band, the total outer diameter of the binding object can be increased, and the convenience can be further enhanced, which is convenient.

[0012]

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a front structure of the binding band A1 according to the present embodiment, and FIG. 2 shows a side structure thereof.
As shown in FIGS. 1 and 2, the binding band A <b> 1 has a tongue piece 1 c extending from the tip side of the ratchet portion 1 a of the head portion 1. The tongue piece 1c does not have a one-sided concave portion 1b formed on the surface of the ratchet portion 1a, the surface is smooth, and the tip 2a of the foot portion 2 is inserted into the gap 3 of the head portion 1. When the object to be tied B is inserted and tied, it is extended slightly downward so as to be separated from the foot 2 as much as possible.

As shown in FIG. 3A, the ratchet portion 1a is provided with a space 5 below the ratchet portion 1a, and the root portion D is formed so as to be biased toward the entrance side where the foot portion 2 is inserted.
As shown in FIG. 3B, the rising of the root portion D is inclined by the angle α, and the tongue piece 1c is separated downward from the inserted foot portion 2 by using a finger. By performing the pulling operation in the direction, the engagement between the convex portion 2b of the foot portion 2 and the concave portion 1b of the ratchet portion 1a of the head portion can be easily released. In other words, the stage in which the objects to be bound are tightened to a certain extent in order to restrain the objects to be bound (temporary tightening)
Then, when a situation in which it is desired to re-bind occurs, the tongue piece 1c is directed downward with a finger and the foot 2 is pulled in a direction away from the head 1 (arrow S), so that the head can be easily moved. The foot part 2 can be pulled out from 1. However, depending on the size of the binding band, the tongue piece 1c may be directed downward using an appropriate pinching tool instead of using the finger to direct the tongue piece 1c downward.
In addition, the rising angle α of the root portion D may be 90 ° as in the prior art, but it is preferable that the rising angle α be 40 to 70 ° because the binding is easily released.

Similarly, in order to strongly restrain the object to be bound,
It is also possible to release the binding after the stage in which the binding object is sufficiently tightened (final fastening). In that case, the binding is easily released by forcibly pushing down the tongue piece 1c by inserting a tool, for example, the tip of a screwdriver into the gap 4 between the foot portion 2 and the tongue piece 1c shown in FIG. it can. That is, since the angle θ between the tongue piece 1c extending from the ratchet portion 1a and the ratchet portion 1a is an obtuse angle, it is easy to insert the tip of the driver into the gap 4, and the screwdriver is firmly fastened and fixed. Even in that case, it can be released. When the angle θ between the tongue piece 1c and the ratchet portion 1a is 120 ° or more, it is preferable because the tool can be more easily inserted.

However, by cutting and removing the tongue piece 1c, insertion of a tool can be facilitated. Even in this case, the binding band according to the present embodiment can be used again, and the binding can be performed again.

As described above, the binding band A1 of the present embodiment
Can easily pull out the foot 2 inserted into the head 1, so that the head 1 can be extended to the tip 2 a of the foot 2.
Can be formed so as to mesh with the ratchet portion 1a, and even if the length is the same as that of the conventional binding band,
The total outer diameter of the binding object can be increased, and higher convenience can be exhibited. In addition, the shapes shown in FIGS. 1 and 2 can be easily manufactured by injection molding because they can be easily die-cut. Therefore, the productivity is high. The cost can be prevented from rising, and the unit price can be kept low despite the added convenience of the function.

Another Embodiment (1) The binding band of the present invention may have a structure as shown in FIG. This binding band A2 has its head 1
0 has a thick tongue base C and a thick root D, and includes a plurality of formed ratchet portions 10a;
The ratchet portion 10a closer to the tongue piece 10c is inclined at an inclination angle δ so as to approach the inserted foot portion 2 side. Has an open structure. With this configuration,
When the foot 2 is inserted into the gap 4 of the head 10 and the ratchet 10a is engaged with the projection 2b of the foot 2, the tongue 10
Since c is elastically deformed downward, the distance between the inserted foot portion 2 and the tongue piece 10c increases, and when the binding is released,
It is convenient to easily pull the foot 2 in a direction away from the head 1 with the tongue 1c downward with the finger, or to easily insert a tool such as a screwdriver into the gap.
Moreover, when the foot 2 is inserted into the gap 3 of the head 10, the tongue 10 c is formed because the inclination angle δ is formed.
The side ratchet portion 10a has an advantage that the force of biting into the convex portion 2b of the foot portion 2 is increased, and the engagement can be strengthened.

When a relatively heavy object to be tied is tied and hung by a narrow tying band of the conventional tying band, the ratchet part of the head part and the foot part are pulled downward by its weight. However, the binding band of this embodiment has a thick tongue base C and a root D, so that the meshing is not possible. It does not come off easily and the object to be bound is hard to drop.

Further, since there is adopted a structure in which the inclination angle δ with respect to the ratchet portion 10a is present and the space 5 located below the tongue piece 10c is greatly opened toward the tip end of the tongue piece 10c, it is manufactured by the injection molding method. In doing so, it is convenient to make the mold easier to remove. In particular, it is preferable that the rising angle γ of the root portion D in the space 5 is formed to be larger than the rising angle β of the ratchet portion 10a on the rear end side, because the die can be easily removed.

Furthermore, since the upper opening 10e on the entrance side of the head 10 where the foot 2 is inserted is slightly widened, the foot 2 can be easily inserted. Of course, such a spread may be formed not only on the upper side of the entrance-side opening but also on the periphery. FIG. 4 shows only the head part of the binding band (the state before the foot part is inserted into the head part).

(2) The tongue piece 1c may have any shape as long as it can be gripped with a finger or a tool, and its shape and size are not particularly limited.
It is preferable that the shape be injection moldable.

(3) As the material constituting the binding band according to the present invention, various thermoplastic resins such as polyamide such as nylon, polypropylene, polyester and polyethylene resin can be used.
