Description

[Detailed Description of the Invention] The present invention relates to a buckle that can be easily fastened to a belt using the abdominal pressure of the body.

Conventional buckles include, for example, those in which a fixing member for fixing the base end of the belt and belt clamping teeth are pivotably attached to the buckle body through which the belt is inserted, and
A fixing member for the base end of the belt is provided on the buckle body itself, and protrusions are fixed near the tip of the back of the buckle body, and the protrusions are fitted into engagement holes drilled at appropriate intervals in the tip of the belt. There are buckle buckles that fit and lock together (so-called box-stop type), but the former buckle not only has a complicated structure and a large number of parts, but also has a thick overall buckle that does not look good. Furthermore, since the latter type has an engaging hole in the tip of the belt, similar to the conventional swivel pin type, the hole gradually becomes damaged and enlarged with use, resulting in a lack of durability.

In view of the above-mentioned drawbacks of the conventional technology, the present invention eliminates the need to drill holes for the belt, allows the entire buckle to be formed into an extremely flat shape, and has a good appearance. To provide a buckle that can be easily fastened just by pressing.

That is, the buckle of the present invention is placed on the side opposite to the belt tip insertion opening, and the belt proximal end fixing member is rotatably pivoted on the sides of the buckle main body, which has a substantially U-shaped cross section, and is guided toward the insertion opening. form a groove,
Pins having a smaller diameter than the rod are protruded from both ends of the rod to which the base end surface of the contact plate curved in an arc shape is fixed, and the pins are slidably fitted into the guide grooves. is inclined so that it gradually approaches the back side of the buckle body as it heads towards the belt tip insertion opening, and the contact plate is tilted towards the rear of the buckle body when the pin is located at the opposite end of the belt tip insertion opening in the guide groove. It is constructed so that a part of it protrudes.

Next, embodiments of the present invention will be described with reference to the drawings.

1 is a flat buckle body with a roughly U-shaped cross section, and the entire body is slightly curved to follow the abdomen of the body.
A fixing member 2 for a rotatable belt base end 4b is provided on the side opposite to the belt tip 4a insertion opening A in the main body 1 and has belt teeth 3 connected to the base. The fixing member 2 is a plate-shaped body, and both sides of its base are pivotally attached to both side walls 1a of the main body, and when the member 2 is turned toward the back of the main body 1, the belt teeth 3 are turned and the belt is fixed. It is designed to be fixed by biting into the base end portion 4b.

Reference numeral 5 denotes a rod-shaped body provided with a non-slip 6 having a plurality of irregularities uniformly formed in the length direction on one half of its circumferential surface, and on the opposite side of the rod-shaped body 5 from the anti-slip 6, there is provided a non-slip 6 with a plurality of irregularities uniformly formed in the length direction of the rod-shaped body 5. The base end face of the contact plate 7, which is curved into a narrow arc shape, is mounted and fixed. There are small engaging pieces 8 facing outward on both left and right sides of the tip of the contact plate 7.
are integrally formed to protrude, and the engaging pieces 8 are configured to be able to engage with the inside of the bent portion 1b formed by further bending the edges of both side walls 1a of the buckle body 1 inward. The tip end of the contact plate 7 is prevented from separating from the bent portion 1b toward the rear and outside of the buckle body.

Reference numeral 9 denotes pins slightly protruding from both ends of the rod-shaped body 5 and having a diameter smaller than that of the rod-shaped body 5. The pins 9 are formed in guide grooves that are cut and formed near the belt tip insertion opening A on the opposite side walls 1a of the buckle body 1. 10 so as to be able to slide freely within the groove 10.

Both guide grooves 10 are inclined so as to gradually approach the back side of the buckle main body 1 as they go toward the belt tip insertion opening A, and the part of the groove 10 opposite to the insertion opening A is inclined at a fairly steep angle to the middle part. 9
The buckle is formed so that it can be easily dropped toward the back of the buckle main body 1, and the tip thereof is gradually inclined gently toward the insertion port A.

Therefore, when the pin 9 is located in the guide groove 10 at the end opposite to the belt tip insertion opening A, as shown in FIG. The base end 4b of the belt 4 is configured to protrude outward, and the base end 4b of the belt 4 is connected to the fixing member 2.
After fixing the belt 4 with When pushed out, the contact plate 7 is pressed by its abdominal pressure, and the pin 9 slides down in the direction of the insertion port A within the inclined guide groove 10, whereby the rod-shaped body 5 and the buckle body 1 The distance between the back and the rod-shaped body 5 becomes narrower.
The anti-slip portion 6 is pressed against the surface of the belt 4, and the belt 4 is securely fixed (FIG. 3B).

The buckle of the present invention is constructed as described above, and when tightening the belt to the body, the belt can be easily adjusted to the desired length steplessly by simply pressing the contact plate protruding from the back of the buckle body with abdominal pressure. It is extremely easy to operate because the belt can be fixed by crimping, and the entire buckle can be made flatter than conventional ones, and the tip of the belt passes inside from the base end of the belt and is not exposed to the outside. Therefore, it has various advantages such as good appearance, simple structure, and easy manufacture.
