DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buckle which is a latching tool used for connecting and fixing belts, bags and other members.

[0002]

2. Description of the Related Art Conventionally, for example, a buckle used for a bag or shoes has a male member and a female member as disclosed in Japanese Utility Model Laid-Open Publication No. A locking step as an engaged portion is formed at a pitch, and a female member is provided with a rotatable locking projection for engaging with the locking step and an operation member for rotating the locking projection. It is a thing. The locking projection is elastically urged and engaged with the locking step by the elastic member, and when the operating member is pressed vertically against the mounting surface of the female member, the elastic force is reduced. In opposition, the locking projection rotates in the disengagement direction, so that the male member can be inserted and removed.

Further, as disclosed in Japanese Utility Model Publication No. 4-36653, a locking claw formed integrally with a female member engages with a locking step formed on a male member, and the female member is provided with a locking claw. A buckle in which an operation member for releasing this engagement is formed on both sides has also been proposed. In this buckle, when the engagement between the male member and the locking claw is released, the operating portions formed on both sides of the female member are pressed from both sides, so that the male member is in a plane parallel to the mounting surface of the female member. By moving the contact portion of the operation unit in a direction perpendicular to the insertion direction of the connector, the locking claw is separated from the locking step by the contact portion, and the male member can be inserted and removed.

[0004]

In the former case of the prior art, when the male member and the female member are disengaged from each other, the operating member is pressed vertically when the female member is attached to a soft member. There was a problem that it was not possible. On the other hand, when it is attached to a hard object, the engagement is released only by pressing it, so in places where people and things are crowded, it is accidentally pushed or the engagement is released. It was dangerous.

In the case of the latter of the prior art, since the operating member is formed on both sides of the female member, the operating member protruding on both sides is caught by a string or other object, and the operating member is damaged. The operation members protruding to both sides are not preferable in appearance.

The present invention has been made in view of the above-mentioned conventional technology, and provides a buckle which is free from malfunction, has less irregularities in appearance, and can easily disengage a male member from a female member. With the goal.

[0008]

According to the buckle of the present invention, when the male member is inserted into the insertion portion of the female member, the locking step and the locking projection engage with each other.
The engaging step is moved in the direction of disengagement by moving the operating member in the direction parallel to the insertion direction of the male member toward the inside of the female member while being securely connected. Away from the male member so that the male member can be inserted into and removed from the female member.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. The buckle of this embodiment is a flexible resin male member 1 attached to the end of one member.
And a female member 12 made of resin, which is attached to the end of the other member and into which the male member 10 is inserted and engaged.
A locking step 1 comprising a plurality of irregularities is provided on the front side of the male member 10.
4 are formed. This unevenness has a slope 14a formed obliquely in the insertion direction of the male member 10, and a vertical portion 14b formed on the opposite side of the slope 14a, and has a sawtooth-shaped cross section. The female member 12 includes a main body member 13 and an operation member 15 provided separately from each other. The female member 12 has an insertion hole 16 as a space through which the male member 10 is inserted. . In the insertion hole 16 formed in the main body member 13, a locking projection 18 that engages with the locking step portion 14 of the male member 10 is formed to protrude inside the insertion hole 16. The locking projection 18 is formed on the insertion hole 16 side of a tongue-shaped elastic portion 20 integrally formed with the main body member 13 so as to be elastically deformable outward of the insertion hole 16. A slope 22 is formed on the distal end edge of the elastic portion 20 so as to be inclined toward the inside of the insertion hole 16.

The operating member 15 communicates with an insertion hole 16 formed in the main body member 13 and is inserted along an insertion portion 24 through which the male member 10 is inserted, and along both side surfaces of the insertion hole 16 of the main body member 13. And a pair of insertion pieces 26 are formed. An outwardly facing engaging portion 27 is formed at the distal end of the insertion piece 26, and the engaging portion 27 is engaged with an edge 16 a of the one end opening of the insertion hole 16. Then, the pair of insertion pieces 26 are inserted in contact with the contact surface 30 of the main body member 13, and the operation member 15 is provided movably in the insertion direction of the insertion piece 26 in a state of being attached to the main body member 13. ing. Further, an edge of the insertion portion 24 facing the slope 22 of the edge of the elastic portion 20 is formed on a slope 32 parallel to the slope 22. The slopes 22 and 32 need only be formed on at least one of them, and may be any as long as the locking member 18 can be pushed up by the movement of the operating member 15 to a height at which the locking projection 18 does not contact the locking step portion 14. The main body member 13 and the operation member 15 of the female member 12 are respectively provided with upright portions 28 for finger hanging,
29 are formed so as to slightly bulge out from the upper surface and face each other.

Next, a method of using the buckle of this embodiment will be described below. Here, the male member 10 is fixed to one member 34 connected to each other, and the main body 13 of the female member 12 is connected to the other member 3 connected to the one member 34.
5 is fixed. First, in order to mount the male member 10 on the female member 12, as shown in FIGS. 1 and 2, the operation member 15 is inserted into the main body member 13 of the female member 12 and mounted, and the insertion hole 16 and the insertion portion 24 are inserted. The male member 10 is inserted into the. Then, the slope 14a of the locking step 14 of the male member 10
Abuts on the locking projection 18 in the female member 12, the elastic portion 20 is elastically deformed by the force in the insertion direction, and the projection of the locking step portion 14 gets over and reaches a desired position. In this state,
If the male member 10 is to be pulled out of the female member 12, FIG.
As shown in FIG.
4b, depending on the force in the pull-out direction.
Is not applied, and the male member 10 cannot be pulled out.

Next, when the male member 10 is moved with respect to the female member 12, the upright portions 28 and 29 are pushed from both sides in a direction parallel to the insertion direction of the male member 10 so as to approach each other. The operation member 15 is relatively moved inward. As a result, the slope 32 of the operation member 15 comes into contact with the slope 22 of the main body member 13, and as shown in FIG.
The elastic portion 20 of the main body member 13 is deformed upward along the arrow, and the locking projection 18 is separated from the locking step portion 14. In this state, the male member 10 is inserted and removed at an arbitrary position, and the upright portions 28 and 29 are inserted.
When the pressing is released, the locking projection 18 is engaged with the locking step 14 again, and the male member 10 is locked at a predetermined position.

According to the buckle of this embodiment, the male member 1
When the engagement between the locking protrusion 18 and the locking step portion 14 is released by displacing the operating member 15 in a direction parallel to the insertion direction of the male member 10 when the engagement between the locking member 18 and the female member 12 is released. Since the engagement is released, it is only necessary to form the raised portions 28 and 29 in which the operating portion slightly swells.
There is no part that is caught by other objects in appearance, and it is hard to malfunction.

The buckle according to the present invention is not limited to the above embodiment. In the above embodiment, an operating member of a female member is provided on the side where the male member is inserted, and the main member of the female member is a male member. In this case, the engagement member can be released and the male member can be simultaneously pulled out by pressing the operating member in the male member distal direction and pulling the male member in the opposite direction. .

[0015]

According to the buckle of the present invention, the engagement between the male member and the female member is released by pressing the operating member in a direction parallel to the insertion direction of the male member. The male member can be reliably pulled out from the female member by a simple operation without any unnecessary catching portion, and by preventing the male member and the female member from being erroneously disengaged from each other. Moreover, a large projection is not required, and the appearance can be improved.
