SUMMARY OF THE INVENTION The present invention provides a novel buckle obtained by conducting research and development for the purpose of solving the above problems.

[0004]

In order to achieve the above-mentioned object, a buckle according to the present invention has an inner belt through hole at an inner end side which is inside when used, and an outer belt at an outer end side which is also outside at the same time. A buckle main body having a belt through-hole formed therein is formed, and in this buckle main body, an upper surface of a portion sandwiched between the inner belt through-hole and the outer belt through-hole is formed as a recess, and a shaft hole is formed at the center of the recess. A fixed side shaft is inserted into the shaft hole, a flange for preventing upward removal is provided at a position corresponding to the lower surface of the shaft hole in the fixed side shaft, and a shoe such as a female hook is provided at a lower end of the fixed side shaft. In addition to providing a mounting portion to the etc., separately form a mouth-holding member having a mouth-holding tooth on one side of a small piece, this mouth-holding member is formed such that the mouth-holding teeth are outward on the bottom surface of the recess. Can slide in and out along the left and right sides of the recess Placed in this state, the mouth stopper is fixed to the upper end of the fixed shaft, and the shaft hole is a long slot in the inside and outside directions so that the fixed shaft can slide in the inside and outside directions. When the fixed side shaft comes into contact, the leading end portion of the above-mentioned biting teeth comes into a retracted position in a state of slightly protruding from the inner edge of the outer belt through hole into the same hole, and the fixed side shaft comes into contact with the outer end of the slot. When the contact position is reached, the leading end of the biting tooth is in the forward position in a state of being close to or in contact with the outer edge of the outer belt through hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the drawings, a rectangular inner belt through-hole 1 is formed at an inner end side portion which is inward when used with metal, and a rectangular outer belt through hole 2 is formed at an outer end side portion which is also outside. Each of the buckle main bodies 3 is opened, and a portion sandwiched between the inner belt through-hole 1 and the outer belt through-hole 2 in the buckle main body 3 is slightly thinned to form a recess 4 at the upper surface of the same. A shaft hole 5 is formed at the center of the shaft hole 4, and a fixed shaft 6 is inserted into the shaft hole 5, and a flange 7 for preventing upward removal is provided at a position corresponding to the lower surface of the shaft hole 5 in the fixed shaft 6. And a female hook 8 at the lower end of the fixed side shaft 6.
Metal downward stopper member 1 having a downwardly-adhered surface and separately having a sawtooth-like mouth-holding tooth 9 on one side of a rectangular small piece.
0, the state in which the mouth-holding teeth 9 are outward on the bottom surface of the recess 4 and the state in which the mouth-stopping member 10 can be moved inward and outward along the left and right projecting walls 11 of the recess 4. And the central position of the biting member 10 is non-rotatably fixed to the upper end of the fixed shaft 6 by caulking, and the shaft hole 5 is formed into a slot 12 extending inward and outward. 10 is slidable inward and outward.
When the fixed side shaft 6 comes into contact with the inner end of the
When the leading end portion is slightly retracted from the inner edge of the outer belt through hole 2 into the hole 2 at the retracted position, and when the fixed side shaft 6 comes into contact with the outer end of the slot 12, The leading end of the inset tooth 9 is located at a forward position in a state of being close to or in contact with the outer edge of the outer belt through hole 2, and is mainly used for adjusting the length of a shoe upper belt, for example. It is intended to be used for.

[0006]

That is, the buckle 13 according to the present invention is attached to the shoe by fixing the female hook 8 to the male hook 15 attached to the tip of the fixed side belt 14 of the upper belt as shown in the figure, for example. Then, the adjustment side belt 16 of the upper belt is first passed through the inner belt through hole 1 from the lower side to the upper side with respect to the buckle 13 and then passed through the outer belt through hole 2 from the upper side to the lower side. It is used in.

While the shoe is mounted and worn as described above, the adjustment belt 16 of the upper belt is moved by the arrow 1 in the figure.
The buckle body 3 is to be moved inward by receiving the pulling force in the direction indicated by 8 from the foot, and then the occlusal teeth 9 of the occlusal stopper member 10 fixed to the fixed side shaft 6. Is so-called biting into the adjustment side belt 16 and the portion of the biting teeth 9 is elastically bent and held, that is, the biting function and the supporting (holding) function are doubled to hold the belt 16 more strongly. It is something that will be.

However, during use, the buckle body 3 may receive a strong force, a weak force, or be in a no-load state in which the buckle body 3 does not receive such force. In some cases, the traction force for moving the inward movement of the outer belt 3 into the hole 2 slightly decreases from the inner edge of the outer belt through hole 2. It stops at the retracted position where it protrudes inward to prevent the biting function state and the gripping function state from being eliminated.

When the adjustment side belt 16 is in a threaded state,
A state in which the tip of the biting teeth 9 slightly protrudes from the inner edge of the outer belt through-hole 2 into the hole 2 and stops at the retracted position and bites into the adjustment side belt 16 (however,
It is important that the belt becomes difficult to penetrate even if it bites too much.) It is important that the belt is selected by carefully examining the thickness and material of the belt, adjusting the thickness, reinforcing and sliding. Needless to say, it is important to stop the backing material or core tape on the back side of the belt for stopping.

[0010]

Since the buckle according to the present invention is as described above, even if the belt is momentarily unloaded, the tip of the biting teeth slightly remains on the inner edge of the outer belt passage hole. The belt protrudes into the same hole and stays in the retracted position to maintain the state in which the belt is lightly bitten, does not cause the belt to loosen, and solves the above problem. It achieves a remarkable effect to completely achieve the purpose of the above.

According to the present invention, the lower end of the fixed side shaft is directly fixed to a fixed side belt or the like without using the hook as described above, the buckle main body is shaped like a flower or an animal, or the buckle main body. Can be obtained by plastic molding, or the shape of the biting teeth can be made into a flat tooth shape or other shapes, and the present invention can be modified or substituted without departing from the spirit of the present invention.
