DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buckle which is used for connecting a belt or the like and has a lock mechanism which can prevent accidental separation in a connected state between a male member and a female member.

[0002]

2. Description of the Related Art Conventionally, in a buckle for connecting a belt, when a male member and a female member are in a connected state, a lock mechanism for locking the connected state is prevented in order to prevent a situation in which an unexpected external force is applied and the buckle is separated. A buckle has been proposed.

As an example of such a buckle, Japanese Utility Model Laid-Open No.
And JP-A-4-221502. In these buckles, the male member includes a pair of flexible arms having an engagement claw, and the female member includes a tubular portion having an engagement portion that can be engaged with the engagement claw. Is provided with a lock mechanism for locking the connection between the male member and the female member.

This lock mechanism has a lock member having a pair of leg pieces capable of preventing the pair of flexible arms from being bent inward during connection, and the pair of leg pieces are provided inside the flexible arm. a locked position to prevent deflection of the is slidably formed between an unlocked position permitting flexing inward of flexible arms. Then, the lock member is manually operated to the lock position to lock the connection state between the male member and the female member, and the lock member is manually operated to the unlock position to perform the separation operation of the male member. I was

On the other hand, there has been proposed an automatic locking buckle which automatically locks the connection state simultaneously with the connection between the male member and the female member (for example, see Japanese Utility Model Publication No. 5-2092).

The buckle is composed of a male member 60 and a female member 65, as shown in FIG. The male member 60 has a through hole 62 that opens in a plate-shaped insertion portion 61 perpendicular to the insertion axis X, and a block 63 that is movable in the insertion axis X direction is provided in the through hole 62. . Female member 65
Is an elastically deformable hook 66 having a claw 67 at its tip.
And flexible pieces 68, 68 which restrict the insertion amount of the insertion portion 61 of the male member 60 and which are bent further in the insertion direction and resilient when inserted deeper.

According to this buckle, when connecting the male member 60 and the female member 65, the distal end 61a of the insertion portion 61 of the male member 60 comes into contact with the claw 67 of the female member 65, and the hook 66
While elastically deforming outward. At this time, when the distal end portion 61a passes through the pawl 67, the pawl 67
Is pushed in the anti-insertion direction, and the claws 67 enter the through holes 62. Then, the distal end portion 61a and the claw 67 are engaged with each other, so that the male member 60 and the female member 65 are connected to each other.

In order to separate the connected male member 60 and female member 65, the male member 60 is inserted further into the female member 65. Due to this deep insertion, the flexible pieces 68, 68 are pushed by the distal end portion 61a of the insertion portion 61 to bend and generate an elastic force in the anti-insertion direction. Also, as the insertion portion 61 enters, the block 63 enters below the claw 67, and the block 63
Due to the resilience of the rubber member 6, it is held between the female members 65.

When the male member 60 is pulled out in the opposite direction,
The block 63 is inserted into the through-hole 62 while being
Relative to the tip 61a. By further withdrawal, the pawl 67 moves from above the block 63 to above the distal end portion 61a, and the insertion portion 61 is withdrawn and separated from the female member 65.

[0010]

However, in such a conventional buckle, a lock member different from the male member and the female member, or a separate component such as a block is required for forming the lock mechanism. It is. Therefore, the number of parts constituting the buckle becomes at least three, and there is a problem that the material cost increases and the assembling work is required. In addition, there is a problem that the cost of the mold for forming the component parts increases and the product price becomes high.

Further, in the former two buckles, the locking operation of the connection is complicated, and there is a possibility that the lock is sometimes forgotten. In the latter buckle, if the male member is excessively inserted into the female member with a strong force, the block 6
3 enters the claw lower portion 67 and becomes separable, and there is a problem that the buckle is separated without being connected. Further, when the separation is forgotten during the separation operation, there is a problem that the connection and the lock cannot be performed unless the separation is completed and then reinserted.

The present invention has been made in view of the above, and it is an object of the present invention to eliminate the need for a special locking mechanism, to automatically lock simultaneously with connection, and to connect to the outside. It is an object of the present invention to provide a buckle with an automatic lock mechanism that can conceal the locked state of the buckle.
