Description

[Detailed Description of the Invention] The present invention relates to a buckle used in a belt for tightening the upper of ski boots and other locking devices. This invention relates to an easy-to-use buckle that is inserted into a female member.

The buckle according to the present invention will be explained based on an example.

As shown in FIGS. 1 to 3, the buckle of the present invention has a belt attachment ring 1 attached to one end of the belt on the upper and lower surfaces of a base 2, and a front surface with leg rods 8, 8 protruding from the back surface. As shown in FIGS. 4 to 7, a male member A is formed by connecting a cover plate 3, and a base 10 is provided with a belt attachment ring 9 protruding from its lower surface to be attached to one end of another belt. It consists of a female member B having a frame forming a fitting chamber 15 on the upper surface and arm parts 12, 12 extending on the left and right outer sides of the frame, and the outer cover plate 3 of the male member A is attached to the surface of the female member B. Both the male and female members A and B are locked together by pressing into the fitting chamber 15 from the side, and both the male member A and the female member B are integrally molded from a strong synthetic resin. It is.

The male member A has a serrated portion 1B around which a belt is wound within the frame of a mounting ring 1 protruding from the upper surface of the base 2, and a pin 1A is formed at the center of the surface.

On the back side of the front cover plate 3 that protrudes downward from the front end of the lower surface of the base 2, reinforcement parts 4, 4 are provided on the left and right sides of the base end of the front cover plate 3, and below the reinforcement parts 4, 4, reinforcement parts 4, 4 are provided. A horizontally long protrusion 5 and a pedestal-like abutment part 6 are sequentially formed in the center of the surface plate 3, and on both left and right sides of the abutment part 6,
The leg rods 8, 8 are provided with locking step portions 7, 7 having downward converging slopes 24, 24 at their tips, respectively.As shown in FIG. This is a configuration in which the interval W is wider than the width L of the cover plate 3.

Next, the female member B is placed on the upper surface of the base 10 at a distance of approximately L.
A fitting chamber 15 is formed inside a framework in which side plate parts 18, 18 of the joists are extended to the left and right, and their tips are connected by an upper plate part 17.

A tilted window 1 is provided on the outside of the left and right side plate parts 18, 18.
Arm portions 12, 12 are extended apart from each other, and pressing portions 14, 14 having inward protrusions 13, 13 are formed at their tips, respectively.

A tongue piece 22 is provided in the fitting chamber 15 inside the left and right side plate parts 18, 18, extending from the base 10, and the surface of the male member A to be inserted into the fitting chamber 15 is provided on the tip surface of the tongue piece 22. A pressing protrusion 2 that elastically supports the back surface of the plate 3
3 is installed protrudingly.

Here, on the tip sides of the opposing inner surfaces of the left and right side plate parts 18, 18, inclined surfaces 19, 19 that widen toward the front side.
, and protruding contact protrusions 21, 21 formed on the same surface as the upper plate part 17 and supporting the back surface of the front cover plate 3 of the male member A are provided at the base end, In addition, the locking step portions 7, 7 of the leg rods 8, 8 that protrude from the surface plate 3 of the male member A inserted into the fitting chamber 15 are in contact with the back surfaces of the tip sides of the side plate portions 18, 18. An opening locking portion 20 formed so that the protrusions 13, 13 of the arm portions 12, 12 can move forward and backward while being locked;
20 is drilled.

Reinforcing parts 4, 4 are provided on both left and right sides of the upper plate part 17 which is held between the base 2 of the male member A and the horizontally long protruding piece 5.
Notches 16, 16 are provided into which the .

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

Next, the method of using the buckle of the present invention will be explained based on FIGS. 8 to 14.

Attach the male member A to one end of the shoe upper tightening belt C, attach the female member B to one end of the other belt C, and adjust the tightening length of the belt C with the belt attachment ring 1 of the male member A. As shown in FIG. 8, if the leg rods 8, 8 are pressed so that the outer cover plate 3 of the male member A is overlapped with the fitting chamber 15 of the female member B, the inclined surfaces of the leg rods 8, 8 are pressed. 24, 24 come into contact with the inclined surfaces 19, 19 of the female member B, the distance between the leg rods 8, 8 becomes narrower, and the back ends 25, 2 of the side plate parts 18, 18
At the same time as it passes through 5, the elastic force causes the leg rods 8, 8 to
is restored, the locking stepped portions 7, 7 of the male member A contact and lock with the opening locking portions 20, 20 of the female member B, and the lower back surface of the front cover plate 3 of the male member A becomes female. Part B
The contact protrusions 21, 21 and the surface of the upper plate part 17 are in contact with each other, and the pressing protrusion 23 at the tip of the tongue part 22 elastically supports the contact part 6 on the upper back surface of the front cover plate 3, Male member A is inserted into female member B.

In order to separate the male and female members A and B, in the state shown in FIGS. 10 to 13, the female member B
When the pressing parts 14, 14 of the arm parts 12, 12 of the male member A are pushed in with the fingertips, the protrusions 13, 13 are pressed against the leg rods 8, 14 of the male member A.
8, the interval between the leg rods 8, 8 is reduced, and the engagement between the locking step portions 7, 7 and the opening locking portions 20, 20 is released, and at the same time, the female Because the pressing protrusion 23 pushes up the surface plate 3 at the abutment part 6 of the male member A by the elastic force of the tongue part 22 of the member B, the leg rods 8, 8 are pushed up by the inclined surfaces 19, 19 of the side plate parts 18, 18.
, and the male member A is released from the female member B.

In this way, the buckle according to the present invention has a configuration in which the male member A is engaged and detached from the surface side of the plate-shaped female member B, so that the insertion distance can be shortened, and the structure is relatively simple. It does not require much space to handle, and therefore can be made into a highly versatile bag.

In addition, the buckle according to the present invention has a projecting piece 5 protrudingly provided on the back surface of the front cover plate 3 in the male member A, and a protruding piece 5 on the inner surface of the base end of the left and right side plate parts 18, 18 of the female member B. Since the abutting protrusions 21, 21 are protruded from the top plate 17, which connects the tips of the parts 18, 18, the male member A does not move freely inside the female member B even during use. The buckle does not move, the attached belt C can be maintained in a tensioned state, and the buckle has an excellent connecting effect.

Furthermore, in the buckle according to the present invention, the pressing protrusion 23 protruding from the tip of the tongue portion 22 extending into the fitting chamber 15 in the female member B elastically presses the back surface of the inserted front cover plate 3. Since the female member B also supports the arm part 1 and has a short insertion distance.
When the tips of 2 and 12 are pinched between fingertips, the surface plate 3 is immediately pushed out of the fitting chamber 15 by the elastic force of the tongue 22, and the male member A can be separated from the female member B very easily and reliably. This makes it possible to create a buckle with excellent operability.
