DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device suitably used for binding a plurality of articles, for example, cables.

[0002]

2. Description of the Related Art Generally, as a binding device used for binding articles such as a cable, a flexible binding band wound around an article, and a binding band integrally provided at one end of the binding band. Is inserted from the other end, and a fixing member for fixing the binding band at a predetermined position is known. By the way, in such a tying tool, it is common to wind the tying band around an article, insert and fix it to a fixing member, cut and discard the portion protruding from the fixing member, and In most cases, the length is set longer assuming other types of articles. Therefore, in the conventional binding device, the length of the binding band to be cut and discarded after the binding is large, which wastes resources.

Conventionally, a technique capable of coping with such a problem has been proposed in, for example, Japanese Patent Application Laid-Open No. 58-90055. In this technique, a binding band wound around an article and a fixing member for holding the binding band in a bound state are separately provided, and unevenness extending in a lateral direction is formed on one surface of the binding band in a longitudinal direction of the binding band. It is provided in parallel at a predetermined interval, and two through holes are formed inside the fixing member, and the insertion of the binding band from one direction into each of these through holes is allowed, And a locking member for restraining the movement of the binding band from moving. Then, one end of the binding band is inserted into one through hole of the fixing member, and the fixing member is positioned at one end of the binding band. In this state, the fixing member is allowed to move only in the direction from one end to the other end of the binding band. Then, after winding the other end side of the binding band around the article,
The other end is folded back toward the fixing member and inserted into the other through hole of the fixing member. Thus, by pulling out one end side of the binding band from one through hole of the fixing member and relatively moving the binding band and the fixing member, the loop of the binding band wound on the article is contracted. We are trying to bind the goods. Here, the end between the one end of the binding band and the fixing member is cut off because it is not necessary for bundling, but another fixing member is attached to one end of the cut banding band, By performing the same processing as the processing, it can be used for binding other articles, and has an advantage that the length of the binding band to be discarded can be minimized.

[0004]

However, the prior art has the following problems. That is, in the related art, in the binding state, both ends of the binding band are held in a parallel state, whereby each end of the binding band is sharply bent at a position protruding from the fixing member. Further, there is a problem that the bending force is concentrated on each of these ends due to the binding force to cause a reduction in strength.

The present invention has been made in view of such a conventional problem, and an object of the present invention is to use a tying band efficiently, suppress generation of waste, and have excellent durability. In providing a tying tool.

In the binding device according to a second aspect of the present invention, the locking projection according to the first aspect is elastically deformed so as to allow the engaging step to pass when the binding band is inserted. It is characterized by being constituted by an elastically deformable piece that returns to an engagement position with the engagement step after passing through the joint. In the binding device according to a third aspect of the present invention, the first locking hole and the second locking hole according to the first aspect are provided side by side along a winding centerline direction of the binding band. It is characterized by the following. A tying device according to a fourth aspect of the present invention is configured such that the first locking hole and the second locking hole according to the first aspect are provided side by side along a winding radial direction of the binding band. It is a feature. According to a fifth aspect of the present invention, in the tying member according to the fourth aspect, the fixing member according to the fourth aspect has a bulging portion that fills a gap formed between the binding band fixed to the fixing member and the article. Is provided. A tying tool according to a sixth aspect of the present invention is characterized in that the locking steps are formed on both surfaces of the tying strip according to any one of the first to fifth aspects. is there. Furthermore, in the tying tool according to claim 7 of the present invention, the engaging directions of the locking steps formed on both surfaces of the tying band according to claim 6 are opposite to each other. It is a feature.

According to the tying tool according to any one of the first to sixth aspects of the present invention, the first locking hole into which the tying band is inserted from one direction and the tying band are formed in the fixing member. A second locking hole to be inserted from the direction opposite to the insertion direction into the first locking hole is formed, and the binding band is formed in the first and second locking holes. Engage with the engagement step,
Since the binding band is provided with the locking projection that restrains the movement in the direction opposite to the insertion direction, in the binding state, each end of the binding band can be held in a state along the binding direction. Thus, the durability can be improved by using almost all of the force acting on the binding band as a tensile load. In addition, by pulling out the binding band from the fixing member, the loop of the binding band can be contracted and bound, and even after cutting and removing the portion of the binding band that does not contribute to binding, the cut binding band is removed. By attaching a new fixing member to this, the cut binding band can be used for binding other articles.
