The present invention relates to a suspender for fasteners, and to a suspender for fasteners capable of fastening suspenders using a single fastener without using a fastener of synthetic resin.

An example of a conventional suspender fastener is shown in FIG. According to this, the conventional fastener consists of a fastening member 6 made of synthetic resin, a fastener 2 made of steel, a fastening piece 4 and a fastener 8. Since the binding member 6 of the synthetic resin needs to be purchased or manufactured separately, and the elasticity of the binding member folded in the U shape is easily removed with time, it is difficult to insert the suspenders between the binding members. In addition, since the binding member 6 often comes out, the outer surface of the binding member is attached to the inner surface of the binding piece 4 and the fastener 8 with an adhesive or the like. However, this increases not only the manufacturing cost of the binding member 6 itself of the synthetic resin, but also the hazardous environment of the worker and the labor and cost according to the use of the adhesive. If the use of the binder 6 of the synthetic resin is eliminated, not only the number of parts of the entire binder can be reduced, but also the labor cost and expenses can be reduced. In addition, because the space between the binding piece 4 and the fastener 8 into which the synthetic resin binding member 6 is inserted is narrow at the inlet side where the suspenders are inserted, the opposite side is wide, so that the binding of the suspenders is mainly at the inlet side. Since the suspenders are not firmly fastened, the failure rate during assembly of the fastening member 6 is considerably high.

Therefore, it is an object of the present invention to provide a suspending tool for suspending a suspenders using a single fastening piece that functions as a binding member without using the binding member of such a synthetic resin.

These objects and other advantages of the present invention will be understood from the following description in more detail with one example.

Figure 2 is an exploded perspective view of the suspenders of the present invention. Suspension fasteners of the present invention is composed of a fastener 20 and the binding piece 30 and fasteners (40). Fixture 20 and fastener 40 are almost the same as fastener 2 and fastener 8 of the conventional suspender fastener of FIG. 1, but at the end 44 of fastener 40 of the present invention, suspenders 46 ) Is configured to be attached. The fixture 20 is composed of a clamping pressing portion 24 and a grip portion 22 provided with a pivot shaft 26. In assembly, the pivot shaft 26 fits into a pivot hole 37 formed in the outer side wall 36 of the binding piece 30 described later. The outer side wall 42 of the fastener 40 is provided with a pivot hole 43 into which the pivot 39 of the binding piece 30 is fitted.

Looking at the binding piece 30 by FIG. 3A and FIG. 3B with FIG. 2, the binding piece 30 is formed by pressing a single flat steel piece. Preferably, the binding piece 30 is made of high elastic spring steel so as to have elasticity when bent into a U shape as described later. The left portion of the binding piece formed as shown in FIG. 3a is bent in a U shape and positioned on the right side as shown by the dotted line in FIG. 3b to form the binding piece as shown in FIG. For convenience, the left part is defined as the binding part 34 and the right part as the support part 32. The binding part 34 includes a side wall 35 and a front wall 35a. The side wall 35 is configured so that its height gradually increases in the direction of the arrow A in FIG. 3B so as to be engaged in parallel with the side wall 48 of the fastener 40 described later. In the present invention, only the side wall 35 has a sawtooth shape, but if necessary, the front wall 35a can be configured as a sawtooth shape. The outer side wall 36 of the support portion 32 is provided with a pivot hole 37 into which the pivot shaft 26 is fitted and a pivot shaft 39 fitted into the pivot hole 43.

The bottom of the fastener 40 is provided with an uneven portion 47 and a serrated surface wall 48. The side walls 48 are formed by cutting the bottom of the fastener 40, and gradually increase in height toward the Puberty hole 43 so that the side walls 35 of the binding surface 30 engage in parallel when the present fasteners are assembled. It is configured to increase by.

4 is assembled with the binding device of the present invention, suspenders 50 is the front wall 35a and side walls 35 of the binding portion 34 of the binding piece 30, the uneven portion of the fastener 40 A cross-sectional view of the state broken down between the 47 and the side wall 48 is shown. As can be seen in this binding state, unlike in the case of using a conventional synthetic resin binding member, according to the present invention, the suspender straps fit almost parallelly as well as between the front wall 35a and the uneven portion 47. The bite is located between the lateral wall 35 of the sawtooth-shaped binding piece 30 and the side wall 48 of the fastener 40, so that the force can be uniformly applied by the teeth of both side walls 35 and 48. Can be firmly fixed. Therefore, the present invention makes it possible to firmly and securely bind the suspenders rather than using a conventional binding member. In addition, since the binding piece 30 is elastically pressed against the fastener 40 by making the binding piece 30 made of high elastic spring steel, it is possible to press the suspenders with greater force.

The binder of the present invention having the configuration as described above is a more economical binder that can reduce the number of parts and eliminate unnecessary manufacturing processes such as the use of adhesive because it does not require a separate synthetic resin binding member. In addition, since the binding portion 34 of the binding piece 30 and the concave-convex portion 47 and the side wall 48 of the fastener 40 of the present invention can be meshed almost in parallel without additional work, assembly is easy. The defect rate is almost zero since the fastener is formed by simple mechanical assembly.
