[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 is a rear view showing a state before engagement of the belt buckle according to the present invention, and FIG. 2 is a rear view showing the engagement state. As shown in the drawing, the belt buckle includes a pair of a male member 1 and a female member 2.

The male member 1 is formed by punching a metal sheet into a predetermined shape and bending the metal sheet so that the upper and lower edges 11a, 11a are folded up on the back side (the front side in FIG. 1). And a tongue piece 12 is continuously provided at the tip (right side in FIG. 1) of the main body 11 so as to be located slightly behind the surface of the main body 11. It is. The tongue piece 12 is formed by notching the upper and lower sides near the base end (closer to the main body) in a concave shape to form a pair of engagement recesses 12a, 12a, and the front end (the right end in FIG. 1) of FIG. As shown in FIG. 3 and FIG. 4, this is formed as an insertion portion 12b by being inclined upward.

Here, the width of the tongue piece 12 at the base end side (the dimension in the upward and downward direction in FIG. 1) is substantially equal to the distance between the upper and lower edges 11 a of the main body 11. Is set.

The female member 2 is formed by punching a metal sheet into a predetermined shape and bending the metal sheet so that the upper and lower edges 21 a are folded up on the back side (the front side in FIG. 1). The main body 21 is formed, and the receiving end 22 is formed by folding the front end side (left side in FIG. 1) of the main body 21. The receiving portion 22 has a width substantially equal to the distance between the upper and lower edges 21a, 21a so as to fit between the upper and lower edges 21a, 21a of the main body 21, and is close to the base end ( A pair of engaging projections 22a, 22a capable of engaging with the engaging recesses 12a, 12a are formed on the upper and lower sides of the upper and lower sides of the main body (the side continuous with the main body). An engagement hole 22b with which the insertion portion 12b can be engaged is provided near the right end. The distal end of the receiving portion 22 provided with the engaging hole 22b is bent obliquely upward so as to be inclined upward as shown in FIGS.

In the drawings, reference numerals 11b and 21b denote belt holding pieces provided on the rear side of the edges 11a and 21a of the male member 1 and the female member 2, respectively.

[0015] The belt buckle of the present invention having the above-described structure is obtained by clamping the belt A between the main body 11 (or 21) and the holding piece 11b (or 21b) as shown in Figs. The male member 1 and the female member 2 are attached to both ends A ₁ and A ₂ of the belt.

In order to connect the two, first, as shown in FIG. 4, the insertion portion 12b of the tip of the tongue piece 12 of the male member 1 is inserted into the engagement hole 22b on the back side of the female member 2, and Measure the match. Next, the rear side (the left side in FIG. 4) of the male member 11 is turned to the front side (the lower side in FIG. 4) of the female member 2 with the engagement portion as a fulcrum. As a result, the tongue piece 12 of the male member 1 is pushed between the upper and lower edges 21a, 21a of the female member 2, and the engagement recesses 12a, 12a provided at both ends thereof are provided with the receiving portion 22. The engagement projections 22a provided at both ends are fitted. Therefore, the male member 1 and the female member 2 are connected so that they cannot move in directions away from each other by the engagement of the engagement projection 22a and the engagement recess 12a. FIG. 3 is a cross-sectional view showing this connection state.

Next, in order to release the connection state, the back surface of the place where the male member 1 and the female member 2 are butted is pressed with a finger, and the male member 1 and the female member 2 are folded in two so that the respective surfaces are folded. The male member 1 and the female member 2 are bent outward (downward in FIG. 4), as shown in FIG. 4, with a click feeling. The tongue piece 12 of the male member 1 fitted between the edges 21a, 21a of the female member 2 comes out of the edges 21a, 21a. Accordingly, the engagement between the engagement projection 22a and the engagement recess 12a is also released, so that the male member 1 and the female member 2 can move in directions away from each other, and the engagement between them is released.

At this time, since the insertion portion 12b inserted into the engagement hole 22b has a small inclination with respect to the engagement hole 22b due to the rotation of the male member 1, there is a gap between the insertion portion 12b and the inner periphery thereof. Occurs, and easily comes out of the engagement hole 22b.

As described above, in the belt buckle of the present invention, the engagement can be easily released only by pushing with a finger so as to fold the connecting portion in half. Moreover, at this time, since both ends A ₁ and A ₂ of the belt are hardly pulled in a direction approaching each other, the wearer does not feel any discomfort such as tightening his belly.

In the above description, a belt worn on the body has been described as an example. However, it goes without saying that the belt buckle of the present invention can be used for a connection portion of various belts such as a bag, a bag, or a baggage fixing device. No.
