A female member is provided with a locking window for locking, and a female member is provided with a mounting ring having a belt mounting hole at the lower end of the enclosure, and an insertion plate is inserted into the enclosure, and the pressing part is inserted into the locking window. The present invention relates to an improvement of a synthetic resin buckle which is removably fitted into and locked into the body.

(Prior art) This type of conventional synthetic resin buckle is as follows:
As disclosed in Japanese Patent Application Laid-open No. 57-164005, the bottom wall facing the locking window of the female member is used as a spring bottom, and the pressing portion of the insertion plate is inserted by the elastic force of the bottom wall. It is known that the device is configured to fit and lock into a locking window.

(Problems to be solved by the invention) In the case of a buckle configured to utilize the elastic force of the elastic bottom as described above, the bottom surface is not smooth and a peripheral frame is formed, and the elastic bottom is in an inclined state. become exposed to the outside.

The formation of this peripheral frame not only makes the body feel uncomfortable but also causes pain because the bottom surface of the peripheral frame is in contact with the body, and if the elastic bottom is exposed, the effect of this The buckle is obstructed by a part of the clothing getting into it, making it difficult to attach and detach the buckle, and the force applied to the pressing part acts on the slanted bottom of the buckle, creating a component force on the insertion plate in the direction of detachment. There are drawbacks such as the insertion plate easily coming off due to inadvertently applied pressing force.

The present invention solves the above-mentioned conventional drawbacks, does not cause any discomfort or pain during use, does not come off carelessly, can be put on and taken off smoothly, and does not have the corners caught on clothing, etc. The purpose is to provide a synthetic resin buckle at a low cost that does not damage fabrics.

(Means for Solving the Problems) The present invention consists of a male member A in which an insertion plate 3 having a pressing portion 5 protruding from the center thereof is connected to a mounting ring 1 having a belt mounting hole 2, and an insertion opening 8. A locking window 10 for fitting and locking with the pressing part 5 of the male member A is bored in the top plate 11 of the provided enclosure part 9, and a mounting ring having a belt attachment hole 13 at the lower end of the enclosure part 9 is provided. In a synthetic resin buckle, the insertion plate 3 is inserted into the enclosing part 9 and the pressing part 5 is removably fitted into the locking window 10. , the insertion plate 3 of the male member A is inserted into the pressing portion 5 at the front and back in the insertion direction of the pressing portion 5.
The main feature of this buckle is that it is integrally formed in a form supported by resilient legs that have resilient force against the pressing direction of the insert plate 3, and that the insertion plate 3 itself has resilient force. .

(Example) Next, the buckle according to the present invention will be explained based on an example. As shown in FIGS. 1 to 6, the buckle according to the present invention is inserted into a mounting ring 1 having a belt mounting hole 2. The male and female members are made up of a male member A in which a plate 3 is connected and a female member B in which an enclosure part 9 for detachably locking the insertion plate 3 is connected to an attachment ring 12 having a belt attachment hole 13. Both A and B are integrally molded from a strong synthetic resin.

The male member A, as shown in FIGS. 1 and 2,
The lower end of the mounting ring 1 having the belt mounting hole 2 (hereinafter referred to as
An insertion plate 3 made of a synthetic resin thin plate having a substantially doglegged shape when viewed from the side is installed in series on the top, bottom, left and right (the top, bottom, left and right are based on the drawing), and this continuous part is made slightly thicker. The tip part 4 is slightly rounded, a substantially rectangular pressing part 5 is protruded from the center, and holes 6, 6, 6, 6 are formed above and below this pressing part 5 to form a spring leg. It is what it is.

The female member B is, as shown in FIGS. 3 and 4,
A substantially rectangular locking window 10 that fits and locks the pressing portion 5 of the male member A is bored in the top plate 11 of the enclosure portion 9, which has an insertion opening 8 at the top for inserting the insertion plate 3 of the male member A. established,
A mounting ring 12 having a belt mounting hole 13 is connected to the lower end of the encasing portion 9.

The male and female members A and B are both integrally molded from a strong synthetic resin.

Note that holes 6, 6,
The purpose of drilling holes 6 and 6 is to adjust the elastic force of the spring legs of the insertion plate 3, which has a substantially doglegged shape when viewed from the side.

Next, to explain how to use the buckle of the present invention, when inserting the insertion plate 3 of the male member A into the insertion opening 8 of the female member B and pushing it in, the insertion plate (3), which is approximately doglegged in side view, will open. The spring leg is sandwiched between the front plate 11 and the back plate 15 of the enclosing part 9 and is slightly elastically deformed, and the tip 4 of the insertion plate 3 is sandwiched between the front plate 11 and the back plate 15 of the enclosing part 9 of the female member B. At the same time, the upper surface of the pressing part 5 of the insertion plate 3 slides along the top plate 11 of the enclosing part 9, and the stepped part 7 of the pressing part 5 passes through the end surface 14 of the enclosing part 9. At the same time, the elastically deformed spring legs are restored by their elastic force, and the pressing part 5 is fitted and locked in the locking window 10, so that the male and female members A and B are fitted and locked, The state shown in FIGS. 5 and 6 is reached.

To release the Km ³ locking of the male and female members A and B from this state, press the pressing part 5 of the male member A and shift it upward, and the step part 7 of the pressing part 5 and the locking part 10 The fitting lock with the end surface 14 is released, and at the same time, the small insertion plate 3 is shifted upward, and the upper surface of the pressing part 5 is brought into contact with the top plate 11.
When the attachment ring 1 of the male member A is pulled, the male member A and the female member B will be separated, and the fitting and locking of the male member A and the female member B will be completed. It will be canceled.

(Operation and Effect of the Invention) As described above, the buckle of the present invention consists of a male member in which an insertion plate with a pressing part protruding from the center is connected to a mounting ring having a belt mounting hole, and a surrounding box provided with an insertion opening. A locking window that fits and locks the pressing part of the male member is bored in the front plate of the insertion plate, and a female member is connected to the female member, which has a mounting ring having a belt mounting hole at the lower end of the enclosure part. In a synthetic resin buckle which is inserted into the enclosing part and the pressing part is removably fitted into the locking window, the insertion plate of the male member, in particular, It is integrally formed in a form supported by resilient legs that have resilient force against the pressing direction of the pressing part, and since the insertion plate itself has resilient force, the pressing part can be attached to the female member by the resilient legs. It will be in a state where it is supported on average within. For this reason, if the pressing part is simply pushed, it will only deform in the direction of the push and no force will be applied in the direction of detachment, so even if pressing force is inadvertently applied to the pressing part, the male and female members A and B will not fit together. The lock cannot be released and the male and female members will not come off inadvertently during use.

In addition, since the female member has a simple and smart structure with a flat cylindrical shape, the structure of the mold can be simplified.
The buckle is easy to manufacture and can be provided at low cost, and the part of the buckle that contacts the body of the female member is smooth, so there is no discomfort or pain in the contact state when using it, and it can be used on clothes, etc. The fabric can be prevented from being damaged by the corner of the female member getting caught.

Furthermore, since the spring legs are formed on the insertion plate itself, the spring legs are not exposed to the outside when the male member and the female member are connected, and therefore, the elasticity of the spring legs is suppressed by resistance due to interference such as clothing. There is an effect that the attachment/detachment operation during the fitting/locking operation can be carried out smoothly without being hindered.
