Benefits of technology

[0007]An advantage of the buckle according to the present invention is high throughput in the manufacturing thereof.
[0008]Another advantage of the buckle according to the present invention is the use of a small amount of material.
[0009]Another advantage of the buckle according to the present invention is to provide a small and light structure.
[0010]Another advantage of the buckle according to the present invention is firm clamping of a strap for using the jaws biased by the elastic element.

Problems solved by technology

Moreover, such zinc-aluminum alloy is soft so that the rigidity of both of the base 1 and the handle 2 is inadequate.
Moreover, a lot of energy is consumed to heat and melt the zinc-aluminum alloy.
In addition, it takes a lot of time for the base 1 and the handle 2 to cool down before they can be finished.
Therefore, the throughput is low.
Furthermore, it costs a lot of money to develop molds for molding the base 1 and the handle 2.

Embodiment Construction

[0019]Referring to FIGS. 1 and 2, there is shown a buckle for fastening a strap according to a first embodiment of the present invention. The buckle includes a base 10, a handle 20, an elastic element 30 and a jaw 40. The base 10 and the handle 20 are made of iron in a continuous pressing or punching process with ease at a low cost.

[0020]The base 10 is made of a first iron sheet including a middle portion and two lateral portions. In the continuous pressing process, the lateral portions of the first iron sheet are bent with respect to the middle portion of the same so that the former extend perpendicular to the latter, i.e., the base 10 is U-shaped in an end view. The middle portion of the first iron sheet becomes a floor 18 while the lateral portions of the same become walls 19. Two openings 11 and 12 are made in the floor 18. The openings 11 and 12 are separated from each other by a crossbar 13 that is part of the floor 18. Two apertures 14 and 15 are made in each of the walls 19....

Abstract

A buckle includes a base, an individual jaw, a handle and an elastic element. The individual jaw is connected to the base. The handle includes a jaw formed thereon. The handle can be pivoted on the base between a first position where the jaw thereof is close to the individual jaw and a second position where the jaw thereof is distant from the individual jaw. The elastic element is used for keeping the handle in the first position.

Description

BACKGROUND OF INVENTION[0001]1. Field of Invention[0002]The present invention relates to a buckle and, more particularly, to an inexpensive buckle.[0003]2. Related Prior Art[0004]Disclosed in Taiwanese Patent 1249996 is a buckle for fastening a strap. The buckle includes a handle 2 pivotally installed on a base 1. The base 1 and the handle 2 are made of zinc-aluminum alloy in an extrusion process. A lot of material is used to form the base 1 and the handle 2. The base 1 and the handle 2 are thick and heavy. Moreover, such zinc-aluminum alloy is soft so that the rigidity of both of the base 1 and the handle 2 is inadequate. Moreover, a lot of energy is consumed to heat and melt the zinc-aluminum alloy. In addition, it takes a lot of time for the base 1 and the handle 2 to cool down before they can be finished. Therefore, the throughput is low. Furthermore, it costs a lot of money to develop molds for molding the base 1 and the handle 2.[0005]The present invention is therefore intende...
