Description

[Detailed Description of the Invention] The present invention relates to a buckle for use in clothing hanging belts, bands, shoe tails, etc., which is composed of a male member and a female member.

The structure of the buckle according to the present invention will be explained based on one embodiment. As shown in FIG. A projecting surface 4 is provided at the center of the surface of the lower rod 3 at the lowest end of the base 2, and two left and right leg rods are provided below the base 2 with an interval similar to an approximately inverted triangular notch 5. 6, 6 are provided, and locking step portions 7, 7 are provided protruding from the inner lower side of the left and right leg rods 6, 6, and concave inclined surfaces 8, 8 are provided below from the locking step portions 7, 7 to the tips. It is a structure formed by forming.

As shown in FIGS. 2 to 5, the female member B forms an encasing portion 10 having a housing hole 9 into which the leg rods 6, 6 of the male member A are inserted and accommodated from the upper part. A belt attachment ring 11 is provided below the portion 10 to which one end of the belt is attached.

A convex central protruding wall 12 is provided on the surface side of the enclosure 10, projecting from the upper end, and a cross-shaped cut line 13 is bored in the center of the central protruding wall 12. A rectangular spring part 14 is formed with a horizontally long rectangular pressing part 15 connected to the lower part of the spring part 14, and this cut line 13 and the storage hole 9 are connected to form an enclosing part. The slopes 16, 1 are in contact with the slopes 8, 8 of the leg rods 6, 6 of the male member A housed in the housing 10, and are sloped from side to side while tilting upward.
It has a structure in which a mountain-shaped expansion protrusion 17 having a diameter of 6 is protruded from the upper part of the back surface of the pressing part 15.

Inside the enclosure part 10, the leg rods 4,
4 is inserted, and a central projecting wall 1 is provided on the inner wall of the front side of the storage hole 9 from the upper end to the pressing part 15.
A groove 18 having a width slightly wider than the width of the upper cut line of the cut line 13 is bored a little narrower than the width of the upper vertical part 25 of the storage hole 9, and a pressing part 15 is formed on the inner wall of the back side of the storage hole 9. An opening 1 having substantially the same shape at a position opposite to
9 is bored, and a triangular prism-shaped locking protrusion 21 having wide sloped walls 20, 20 is attached to the sloped walls 20, 2.
The lower ends 22, 22 of the opening 19 are protruded so that they are located at the center of the upper end of the opening 19, and the locking protrusion 21 is connected to the back surface of the spring part 14 so that the spring part 14 can be bent toward the storage hole 9. A gap 23 is formed between the top surface of the male member A, and the width of the lower left and right ends 22, 22 is determined from the width l between the inner ends of the locking steps 7, 7 of the leg rods 6, 6 of the male member A. The lower end 22, 2 is also formed slightly wider.
2 are formed with locking portions 24, 24.

A belt attachment ring 11 is continuously provided below the opening 19 of the enclosing part 10.

These male and female members A and B are each integrally formed from a strong synthetic resin.

Next, to explain how to use the buckle of the present invention, attach one end of the desired belt to the belt attachment ring 1 of the male member A, and then attach it to the belt attachment ring 1 of the female member B.
After attaching one end of the belt whose length has been adjusted to Left and right inclined walls 2 of the triangular prism-shaped locking protrusion 21 of the female member B
A locking protrusion 21 that comes into contact with 0 and 20 and has a wide hem
is pushed out along the left and right inclined walls 20, 20,
When the locking steps 7, 7 of the leg rods 6, 6 pass the lower ends 22, 22 of the left and right inclined walls 20, 20 of the locking protrusion 21, the leg rods 6, 6, whose width has been expanded until now, become elastic. The locking step portions 7, 7 abut and lock with the locking portions 24, 24 of the locking protrusion 21, and as shown in FIGS. 6, 7 and 7. As shown in FIG. 9, the male member A and the female member B are fitted and locked.

To release the male and female members A and B, press down the pressing part 15 of the female member B with your finger in the state shown in FIG.
9 is bent into the gap 23, and the expansion protrusion 17 protruding from the back surface of the pressing part 15 is also pressed down, resulting in a state as shown by the chain line in FIG.

At this time, the left and right slopes 16, 16 of the expansion protrusion 17
The leg rods 6, 6 that were in contact with the left and right slopes 1
6 and 16 are tilted in the left-right direction, so that they are pushed apart in the left-right direction, resulting in a state as shown by the chain line in FIG. At the same time, the sloped surfaces 8, 8 of the leg rods 6, 6 are inclined downwardly, and the left and right slopes 16, 16 of the expansion protrusion 17 are slightly inclined upward, so that the leg rods 6, 6 is pushed up perpendicularly to the left and right slopes 16, 16, and the locking step portions 7, 7 of the leg rods 6, 6 and the locking protrusion 2
The locking with the locking part 24 of 1 is released. At the same time, since the ends of the locking steps 7, 7 of the male member A are tapered slopes 8, 8, the left and right sloped walls 20, 20 of the locking protrusion 21 of the female member B are Since the hem is widened downward, the leg rods 6, 6, which are pushed out and released, spring inward.
Due to this elastic force, the left and right sloped surfaces 8, 8 of the lower depressions at the bottom of the leg rods 6, 6 strongly slide from diagonally downward to diagonally upward so as to pinch the left and right sloped walls 20, 20 of the locking protrusion 21. The male member A is automatically released from the female member B, separates and flies out.

In addition, in the above embodiment, the enclosure portion 10 of the female member B
Although the convex central projecting wall 12 is provided protrudingly on the surface side, the shape is not limited to the convex shape, and
The central protruding wall 12 may be omitted by increasing the thickness of the entire surface side of the enclosing portion 10.

In this way, the buckle according to the present invention has a male member A.
The locking can be easily and reliably performed with only one operation of pressing and inserting the leg rods 6, 6 into the storage hole 9 of the female member B. Further, in order to separate and release the male member A and the female member B, slopes 8, 8 are formed on the leg rods 6, 6 of the male member A, and slopes 16, 8 are formed on the back surface of the pressing portion 15 of the female member B.
16, and a locking projection 2 having inclined walls 20, 20 in the storage hole 9 of the female member B.
1 is provided in a protruding manner, the male member A automatically pops out from the female member B by simply pressing the pressing portion 15 of the female member B with a finger, and has an excellent effect that can be performed with one operation. Therefore, the operation of separating the male and female members A and B is extremely simple and easy, and there is an advantage that the operation can be performed even when wearing gloves when used in ski boots and the like.

Furthermore, since the male member A and the female member B are each integrally molded from synthetic resin, beautiful colors can be obtained and they can be provided economically.
