BEST MODE FOR CARRYING OUT THE INVENTION

An example of the present invention, to which the said characteristics are applied, is below described in detail by reference to the accompanying drawings.

FIG. 1 is an exploded perspective view showing the construction of a belt according to the present invention. FIG. 2 is a view showing the state before a belt is inserted into a buckle according to the present invention. FIG. 3 is a view showing the state that a belt is inserted into a buckle according to the present invention.

As shown in the drawings, a buckle (B) according to the present invention has a fastener (20) for securing the one end (2) of a belt (1) formed in the one side thereof and a body for fastening a belt (1, 3) in the other side thereof.

That is to say, in the one side of the said fastener (20), an inlet is provided so that the one end of a belt (1) gets to be inserted and secured. Since the construction of the said fastener (20) is typical, specific description thereof is omitted.

And an inlet (12) and an outlet (13) are provided right and left in the said body so that a belt (1, 3) gets to go through the said inlet (12) and out of the outlet (13).

Meanwhile, a fastening plate (10, 11) is respectively installed in the upper part and the lower part of the said elastic movable plate (30), and an elastic movable plate (30), which has an arch shape that its center is convex, is installed inside the said body.

And, a boss (31) is respectively provided in four corners of the said elastic movable plate (30), and an oval groove (15), into which the said boss gets to be inserted, are respectively formed right and left in the both side plates (14) of the body.

The said oval groove (15) can be formed in the form of an oval hole so that the boss (31) may be movable depending upon the elasticity of the elastic movable plate (30).

Since each boss (31) of the said elastic movable plate gets to be inserted into each corresponding oval groove (15) or hole, the elastic movable plate gets to be elastic and movable with its position not be deviated.

Meanwhile, if a user inserts the belt (1, 3), which was in the state as shown in FIG. 2, through the inlet (12) of the body as much as he/she wishes, as shown in FIG. 3, the said elastic movable plate (30) gets to be pushed down by the force resulting from the thickness of the belt (1), and if the user stops inserting the belt (1, 3), the belt (1) gets to be compressed between the upper fastening plate (10) of the body and the elastic movable plate (30) and thereby the belt (1) gets to be fixed.

As described above, since the belt (1) gets to be compressed between the elastic movable plate (3) and the upper fastening plate (11) of the body by the elasticity of the elastic movable plate (3) and thereby the belt (1) gets to be fixed, there is no need to provide a hole or a raised spot in the belt in order to fix the belt, and when a user applies a greater strain to the abdomen than the fastening force of the buckle, the belt gets to be naturally loosened toward the inlet (12) of the body so that it can make the user feel comfortable.

And, if a user wishes to loosen the belt (1) in the state that the belt is compressed between the upper fastening plate (10) of the body and the elastic movable plate (30), all he/she has to do is draw the belt (1) in the direction of the inlet (12) by hand.

Mode for the Invention

Meanwhile, the compressive force between the upper fastening plate (10) and the elastic movable plate (30) can be enhanced by making the upper fastening plate (10) and the elastic movable plate (30) of a magnet having a magnetic force, and if they are made of a magnet, it is natural that the upper fastening plate (10) and the elastic movable plate (30) should be opposite each other, having an opposite pole.

FIG. 4 is an exploded perspective view showing another example of a buckle according to the present invention.

As shown in the drawing, the compressive force between the upper fastening plate (10) and the elastic movable plate (30) can be enhanced by installing springs between the bottom face of the elastic movable place (30) and the lower fastening plate (11) of the body. In this case, it is preferable to fix the position of each spring (40) by providing a boss (41) for insertion of each spring respectively in the lower fastening plate (11) of the body so that each spring may not be deviated from the position thereof.

And, since the buckle's construction is to fasten a belt between the upper fastening plate (10) and the elastic movable plate (30), its function remains unchanged without the lower fastening plate (11) of the body.

In the buckle of the present invention, the fastening plate (10, 11) and the elastic movable plate (30) can have various shapes, and thus, various modifications of the design of each part within the scope of the present invention fall to be under the scope of the technical idea for the present invention.
