Description

[Detailed description of the invention] The present invention relates to a buckle that is used as a locking tool for shoes, clothes, etc., and is composed of a male member and a female member. The leg rod is not inserted from above into a storage hole with an open top of the female member and pressed to fit and lock the two, but the legs of the male member are inserted into the storage hole of the female member with an open front. This relates to a buckle that fits and locks the two rods together by overlapping them and pressing them together.

To explain the buckle according to the present invention based on an embodiment, as shown in FIG. It is fitted and locked by pressing.

As shown in FIG. 1 (rear view), the male member A has a base 2 provided with a belt attachment ring 1 for attaching one end of the belt to the upper part, and a plate-shaped front plate on the rear surface of the lower end of the base 2. 3 are connected in a row, a fitting hole 4 is bored in the center of the lower part of the front plate 3, and a protrusion 5 is provided in the center of the front surface of the front plate 3 to protrude from the lower end of the base 2 to the fitting hole 4. do.

Two leg rods 6, 6 are hung on the left and right from the lower end surface of the base 2, the lengths of the leg rods 6, 6 are made slightly shorter than the length of the front plate 3, and the width of the left and right leg rods 6, 6 is made slightly shorter than the length of the front plate 3. The width of the leg rods 6, 6 is narrower than the width of the front plate 3, and a gap is provided between the front plate 3 and the tip of the leg rods 6, 6, as shown in FIG. The parts 7, 7 are formed. As shown in FIG. 3, stepped portions 8, 8 are provided on the outside of the leg rods 6, 6, and locking surfaces 9, 9 are provided on the rear side of the bulged portions 7, 7.
The outer spacing between the left and right bulging portions 7, 7 is set to be equal to or slightly narrower than the width of the front plate 3.

The middle plate part 1 is located at the upper part between the front plate 3 and the leg rods 6, 6.
0, 10 are provided, the base 2, the front plate 3 and the leg rods 6, 6.
It has a structure in which each of them is strongly integrated.

As shown in FIGS. 4 to 9, the female member B has a storage section 11 that is symmetrical and has an open front.
It has a structure in which a base part 13, which is provided with a belt attachment ring 12 to which the other end of the belt is attached, is connected to the lower part of the belt.

The housing portion 11 is for fitting and locking the male member A, and has left and right side walls 15 on both sides of the rear plate 14.
15, and its front side is open.

At the outer upper ends of the left and right side walls 15, 15, arm portions 17, 17 are provided with inclined windows 16, 16 slightly wider apart.
protrusions 1 that press the outside of the bulging parts 7, 7 of the male member A on the inside of the lower ends of the arm parts 17, 17.
8, 18 are formed, and the inner distance between the left and right side walls 15, 15 is approximately equal to the width of the front plate 3 of the male member A, so that the two can be fitted together.

Both sides of the back surface of the front plate 3 of the male member A and the corresponding abutment walls 19, 19 are made slightly lower than the height (thickness in the front and back direction) of both side walls 15, 15, so that both side walls 15,
15 from the upper side to the lower end.

The distance between the left and right contact walls 19, 19 is made slightly narrower than the distance l between the outer ends of the bulging portions 7, 7 of the male member A, and the lower end surfaces 2 of the contact walls 19, 19 shown in FIG.
0, 20, locking protrusions 21, 21 that abut and lock with the locking surfaces 9, 9 of the leg rods 6, 6 of the male member A.
are provided protrudingly, and openings 22, 22 are formed between the lower end surfaces 20, 20 and the upper surface of the base 13.

The rear plate 14 has openings 2 on the left and right sides of the lower front surface thereof.
Forming concave portions 23, 23 facing inward from 2, 22 and abutting with the bulging portions 7, 7 of the male member A,
A fitting protrusion 24 that fits into the fitting hole 4 of the male member A is protruded in the center between the left and right recesses 23, 23, and a base 13 is connected to the lower part of the rear plate 14. .

The male member A and the female member B are both integrally formed of 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 base 2 of the male member A.
Attach the other end of the belt to the base 13 of the female member B, and insert the leg rods 6, 6 of the male member A into the open storage section on the front of the female member B, as shown by the two-dot chain line in FIG. 11 and pressed, the outer sides of the bulging parts 7, 7 of the leg rods 6, 6 of the male member A come into contact with the inner front parts of the locking protrusions 21, 21 of the female member B, and the male member When the front plate 3 of A is pressed against the female member B, the bulging parts 7, 7 that come into contact with the locking protrusions 21, 21 are narrowed toward the rear, so they are pushed inward and narrowed. It will be done.

The locking surfaces 9, 9 of the bulges 7, 7 are the locking protrusions 2.
After passing through the rear end surfaces 25, 25 of 1, 21, the restrictions on the leg rods 6, 6, which have been reduced until now, are released, and the elastic force of the leg rods 6, 6 restores the leg rods 6, 6 to their original shape. The locking surfaces 9, 9 of the leg rods 6, 6 are connected to the locking protrusions 2.
At the same time, both back surfaces of the front plate 3 of the male member A abut against the front surfaces of the contact walls 19, 19 of the female member B, and the front plate 3
The fitting hole 4 of the female member B is fitted into the fitting protrusion 24 of the female member B, and the male and female members A and B are fitted and locked to each other.
The state will be as shown in FIGS. 0 and 11.

To release the male and female members A and B, in the state shown in FIG.
When 7 is pressed from the left and right sides with fingers, the protrusions 18, 18 press the outside of the bulges 7, 7 of the leg rods 6, 6 of the male member A, and the left and right leg rods 6, 6 are pressed inward and narrowed. and the locking surfaces 9, 9 and the locking protrusions 21, 21 are unlocked (the state shown by the two-dot chain line in FIG. 11),
Male member A is released from female member B.

In this way, the buckle according to the present invention has a male member A.
The locking can be done extremely easily and reliably by just one operation of overlapping the leg rods 6, 6 with the housing part 11 of the female member B and pressing them. Also, since this operation is extremely simple, it can be done with one hand, and the The locking is also reliable.

In the state shown in FIG. 10, the male and female members A and B that have been fitted and locked are
By fitting the fitting protrusion 24 of the female member B into the fitting hole 4, the front plate 3 of the male member A is fitted between the side walls 15, 15 of the female member B against external forces in the left and right direction. By being fitted together, the leg rods 6, 6 of the male member A are able to resist the locking protrusions 21, 21 of the female member B against external forces in the front-rear direction.
Since each part resists by being locked to the buckle, the external force applied to the buckle is shared between each part, and the external force can be resisted without making each part unnecessarily large.This allows the buckle to be made compact as a whole. can.

Furthermore, since the male member A is provided with the front plate 3, the leg rods 6, 6 can be protected from the front.
