Description

[Detailed Description of the Invention] The present invention relates to a buckle as a belt fastener.

As shown in FIGS. 1 and 2, in the conventional buckle of this type, one end side of opposing side walls 11, 11 is bent to face each other to form belt guides 12, 12, and the other end side of the side walls is bent. A first top plate in which shaft holes 13, 13 are formed and one end of both side walls 20, 20 are bent to form mounting arms 21, 21 for the first top board 1, and shaft holes 22, 22 are formed in the mounting arms. , and bend both sides of the other end in the opposite direction to the mounting arms 21 , 21 to form shaft holes 24 , 24 in the bent pieces 23 , 23 .
The second top plate 2 is provided with saw teeth 32 arranged in a row on a bent piece 31 at one end, and the second top plate 2 is provided with saw teeth 32 on both sides of the bent piece.
Belt mounting member 3 with protruding shafts 33, 33 that fit into shaft holes 24, 24 of top plate 2 and are rotatably mounted.
Then, the protrusions at both ends of the insertion shaft 4 are passed through and protruded into the shaft holes 22, 22 of the mounting arms 21, 21 of the second top plate 2, and the protrusions are passed through the shaft holes 13, 13 of the first top plate 1. The second top plate 2 is connected to the first top plate 1 so as to be relatively rotatable, and the belt pressing member 5 has an eccentric cam surface 53 having an uneven surface.

Therefore, with the belt attachment member 3 open as shown by the chain line in FIG.
When the belt mounting member 3 is inserted between the belt mounting member 3 and the belt mounting member 3, and then the belt mounting member 3 is rotated and closed as shown by the solid line in the figure, the saw teeth 32 bite into the belt 6 and the belt is attached to the second top plate. Press and hold on the back side of 2.

When the belt 6 is hung on a hanger (not shown) with the buckle attached as described above and displayed at a store, the first top plate 1 will be tilted relative to the second top plate 2 as shown in Figure 2. This will hinder the exhibition effect. Further, when the belt 6 is worn on the body and the belt 6 is tightened, there is a risk that the belt 6 may loosen unless the second top plate 2 is always pressed against the first top plate 1.

The present invention was proposed in view of the above, and provides a buckle that automatically enters the belt holding state when the hand is released, prevents the gap between the first and second top plates from opening, and is easy to assemble. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a vertical sectional front view of the buckle of the present invention in an assembled state, in which the same parts as in FIGS. 1 and 2 are given the same reference numerals, and FIG. 4 is an exploded perspective view.

As shown in FIGS. 3 and 4, the present invention provides a belt guide 12 between one end side of opposing both side walls 11, 11, and forms shaft holes 13, 13 on the other end side of the both side walls. A first top plate 1 has a stopper 14 protruding inside and a spring receiver 15 passed between both side walls, and mounting arms 21, 21 for the first top plate 1 are provided at one ends of opposing side walls 20, 20. extend and attach the first
Shaft holes 22, 22 are formed, second shaft holes 24, 24 are formed at the other ends of the side walls 20, 20, and engaging protrusions 25 are formed at the side ends from which the mounting arms 21, 21 extend. Saw teeth 32 are arranged in rows on the formed second top plate 2 and the bent piece 31 at one end, and the second top plate 2 is provided on both sides of the bent piece.
A belt attachment member 3 has protruding shafts 33, 33 that fit into second shaft holes 24, 24 of the top plate 2 and are rotatably attached, and an engaging portion 51 for the second top plate 2 and an intermediate portion thereof. A cutout recess 52 is formed to expose the insertion shaft 4, and both ends of the insertion shaft are made to penetrate and project into the first shaft holes 22, 22 of the mounting arms 21, 21 of the second top plate 2, and the projections are inserted into the first shaft holes 22, 22 of the second top plate 2. A belt pressing member 5 which connects the second top plate 2 to the first top plate 1 so as to be relatively rotatable through shaft holes 13, 13 of the first top plate 1, and has an eccentric cam surface 53 as an uneven surface; It is wound around the exposed shaft part of the notch recess 52, and one end is hooked on the spring receiver 15 of the first top plate 1, and the other end is hooked on the second top plate 2, so that the second top plate 2 is always connected to the second top plate 2. 1. The spring 7 is pressed against the stopper 14 of the top plate 1.

Since the present invention has the above structure, the second top plate 2 is always pressed against the stopper 14 of the first top plate 1 by the spring 7. Therefore, there is no inconvenience caused by the gap between the first top plate and the second top plate, which prevents the exhibition effect as in the conventional buckle. In addition, the belt 6 passed between the first top plate 1 and the belt pressing member 5 is instantly pressed and held against the back surface of the first top plate by the belt pressing member, so that the belt is held securely and used. There is no unnatural loosening of the belt inside. Since the spring 7 is wound around the shaft 4 exposed in the notched recess 52 of the belt pressing member 5, there is no need for any special member or space for installing the spring, and the coil spring can be inserted into the notched recess and attached to the belt pressing member. Since it is only necessary to insert the shaft, there are advantages such as easy assembly, compact size, and inexpensive construction.
