Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a buckle for a clothing belt.

(B) Conventional technology When manufacturing a buckle, the entire buckle is integrally cast or formed by punching a thin metal plate such as an iron plate or an aluminum plate.

Further, when the covering material is attached to the surface of the buckle, the covering material is wrapped from the inside to the outside, and the mating portion is hung with a sewing machine.

(C) Problems to be solved by the invention However, such an integrally molded product may be too heavy depending on the part to be used, its strength may be low, plating on the surface may be difficult, or the shape after molding may be changed. Can not.

In addition, the work of wrapping with a covering material and hanging the sewing machine is difficult, and it can be done only by manual work by a skilled person, and mass production of uniform quality is impossible.

In addition, the stitched part that hangs on the sewing machine protrudes outward from the buckle body, its end is caught by fingers, etc., and it is easy to flip the boundary between the covered part and the uncovered part There was a problem such as being lost.

(D) Means for Solving Problems The invention of the present application is intended to address these problems, and the object was achieved by completing the invention described below.

In the buckle of the present invention, a base (1) having a bar-shaped belt stopper (3) and a slightly curved dish-shaped metal fitting (4) provided at both ends is integrally formed by a method such as rubber casting. A cylindrical caulking leg (7) is fixed to the inside of the metal fitting (4) by brazing or the like, the cored bar (2) is formed by casting or the like, and caulking holes (9) are provided at both ends. Next, the buckle is fixed by hitting the swaged foot (7) of the base body (1) through the swaged swaged lid (8) through the swaged hole (9). At this time, the forming method of the base body (1) and the core metal (2) is not particularly limited, and the crimping foot (7) may be integrally formed with the base body (1) from the beginning.

Further, an adhesive is applied to the surface of the cored bar (2), and the covering materials (5) and (6) such as leather and cloth are pressure-bonded to the front and back to integrate the whole, and the periphery of the cored bar (2) After the portion is sewn with a sewing machine, it is punched out by a punching metal fitting and fixed to the base body (1) by a caulking lid (8) to form a stitched wrapping buckle.

The buckle of the present invention can be used not only for clothing but also as a buckle for a bag or the like.

(E) Action As described above, the base material (1) and the core metal (2) are separately molded, and both are fixed by the caulking lid (8). You can choose.

In addition, since the entire core metal (2) is wrapped with the covering materials (5) and (6), there is no break in the stitch portion, the fingers are not caught by the user during use, and the covering material is wrapped. By overlapping and fixing the core metal (2) on the decorative metal fitting (4), the opening when the covering material is wrapped is eliminated, and the covering material is not turned up and damaged.

(F) Effect of the device With this device, various materials can be effectively used.

Further, when the covering material is applied, the stitch portion is not discontinuous, and the stitch portion can be clean not only on the outer side but also on the inner side. Therefore, it is possible to provide a product having a design that has never existed before.

Furthermore, since it can be performed without manual work by a skilled person,
It became possible to mass-produce mechanically.
