Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band used for binding an object to be bound such as a harness wired in an engine room of an automobile and fixing and holding the bound object on a mounting body such as a panel. It is a thing.

[0002]

2. Description of the Related Art This type of binding band that has been generally used in the past was an integrally molded product made of synthetic resin. More specifically, as shown in FIG. 6, a main body 101 that is press-fitted into a mounting body P such as a panel, and teeth 102 in a continuous row are formed on substantially the entire surface of one side of the main body 101. And a flexible strip 103 extending in the mounting direction of the mounting body P (vertical direction in FIG. 6). The distal end portion 103a of the flexible strip 103 wound around the object to be bound M at right angles to the mounting direction (vertical direction in FIG. 6).
A band insertion hole 104 through which the elastic band is inserted is formed, and the band insertion hole 104 can be elastically engaged with the teeth 102 of the flexible band 103 inserted into the insertion hole 104. A locking claw portion 105 that prevents the flexible strip 103 from coming off is formed. An elastic engagement leg 107 with a flange 106 is integrally formed on the lower surface of the main body 101 with respect to the mounting hole H on the mounting body P side by a pressing operation.

When using the conventional binding band having the above-described structure, the flexible band 103 is wound around the object to be bound M such as a harness, and then the flexible band 103 is wound. The tip end portion 103a is inserted into the band body insertion hole 104 of the main body 101 and is pulled in the direction of arrow A in FIG. 6 to tighten and bind the object to be bound M. At this time, the teeth 102 on the side of the flexible strip 103 are elastically engaged with the locking claw portions 105 on the side of the main body 101 to be prevented from coming off.
The tightly bound state is maintained. After such tightening and binding, the elastic locking leg 107 is pushed into the mounting hole H of the mounting body P from above, whereby the object to be bound M can be fixedly held by the mounting body P.

[0004]

In the conventional binding band having the above-mentioned structure, the main body 101 and the flexible band 103 are integrally molded of synthetic resin, and therefore the flexible band 103 is formed. In order to support various specifications such as the binding diameter according to the above, it is necessary to manufacture and prepare a plurality of types of bands having different shapes such as the length and width of the flexible strip 103,
Therefore, there are disadvantages that the manufacturing cost is increased and the management is difficult because there are many kinds.

Further, the flexible strip 103 is formed by the main body 101.
Since it extends in the mounting direction to the mounting body P (vertical direction in FIG. 6), when the flexible band 103 is wound around the object to be bound M and bound. The center of the object to be bound M is the center of the main body 101, in other words, the mounting body P.
Is displaced in the horizontal direction or the like with respect to the center of the mounting hole H, and the amount of the displacement becomes large, and the object to be bound M is attached to the mounting body P.
If it even hangs down to the side, the attachment work itself is hindered by the object to be bound M, which makes it very difficult to perform. Further, there is a problem that the state of attachment to the attachment body P is not stable, and the elastic engagement leg 107 is unnecessarily stressed and is easily broken.

The present invention has been made in view of the above circumstances, and can easily cope with various specifications such as the diameter of the object to be bound, thereby reducing the manufacturing cost and easiness of management. Another object of the present invention is to provide a binding band that can improve the workability of attaching to the attachment body.

[0007]

In order to achieve the above object, a binding band according to the present invention has a main body having a push-in mounting portion for a mounting body and a row of teeth on one surface, and the base end portion thereof has A flexible band for binding a bound object connected to the main body, wherein the main body is wound around a bound object in a direction orthogonal to a mounting direction to the attachment body A band insertion hole for inserting the distal end portion of the flexible band is formed. The band insertion hole is elastically engaged with the teeth of the flexible band inserted through the insertion hole. In a binding band formed with elastic locking claws for preventing the flexible band from coming off, the main body and the flexible band are formed separately, and the main body and the flexible band are penetrated through the band insertion hole. The flexible strip is allowed to pass through in the same direction as the direction, and the base end of the flexible strip is removed. It is obtained by forming a hole for band member mounting for locking in order form.

In the binding band having the above structure, it is desirable that the band attaching hole on the main body side is formed so that a part of the band inserting hole is also used.

[0009]

According to the present invention, the flexible band member is inserted from the tip end side into the band member mounting hole on the main body side, which is molded separately, and the base end part is pulled out to the main body side. By locking in a stopper shape, the flexible band and the main body are assembled into a predetermined binding band. In this assembled state, after winding the flexible band around the object to be bound,
By passing the distal end of the flexible band through the band insertion hole on the main body side and pulling the flexible band, it is possible to tighten and bind the object to be bound in a predetermined manner. The teeth on the band side are elastically engaged with the locking claws on the main body side to be prevented from being pulled out, so that the tightly bound state is maintained.

Here, since the main body and the flexible strip are molded separately, according to the specifications such as the diameter of the material to be bound,
One of a plurality of types of flexible strips having different shapes such as length and width can be arbitrarily selected to meet the above specifications, and the selected flexible strip can be assembled to the main body as described above. It is possible to easily deal with a small number of products with a large number of specifications by using them as a result, and thus the manufacturing cost can be reduced. Further, since the flexible strip is inserted into the strip attachment hole on the main body side and attached to the main body side, a bundled state can be obtained in which the center of the object to be bound is located at the center of the attachment holes of the main body and the attachment body. The work of attaching the bundled object to the attachment body becomes easy, and the attachment state can be stabilized.

In particular, when forming the band mounting hole on the main body side so that a part of the band insertion hole is also used, it is sufficient to form one hole in the main body, and the resin molding itself is easy. And it will be cheaper.
