Referring to these drawings, the buckle device of the present invention includes a band 100 and a buckle 200 for providing slide interlocking of the band 100.

In the band 100, a plurality of locking protrusions 120 are arranged at regular intervals on the back surface of the body 110. In the band 100, the body 110 forms a certain width and length by injection, and the engaging protrusion 120 is formed in the shape of an embossing protrusion on the back surface.

At this time, in the body 110, the slide protrusion 130 having the sewing groove 140 sewn to the fixed chamber P3 is formed on the adherend P-2 at the center in the longitudinal direction, 140 are formed in a state in which the locking projections 120 are divided at regular intervals.

The buckle 200 includes a plate spring 250 for fixing or releasing the forward and backward movements of the band 100 to and from the buckle main body 210, an adherend P-1 and a fixing pin P- And the discharge port 230 is formed by the front and rear portions 201 and 202 and both side portions 203 and 204 in a state where the connection portion 260 is formed.

The buckle body 210 is formed by press-forming a metal plate developed by a sheet metal as shown in Fig. 8, by bending by stepwise bending (bending) as shown in Fig. 9, 203 and 204 and a front part 201 are formed on the insertion port 220 and an insertion port 220 and an outlet port 230 are formed on the insertion port 220. The plate spring 250 and the discharge port 230 are integrally bent on the insertion port 220 side, -1) is formed.

A guide slot 205 in which the slide protrusion 130 of the band 100 is received and slidable is formed in the longitudinal direction on the rear face portion 202 by bending molding of the buckle body 210, The plate spring 250 and the connection part 260 for connection with the adherend P-1 and the fixing pin P-4 are integrally formed by bending the inside of the base plate 250. [

At this time, the connection portion 260 is provided with a fixing groove portion 261 for an inner space in which a fixing pin P-4 for forming an inner space and fixing the fixing member P-1 is folded.

The connecting portion 260 has a hole formed at the center thereof so that the two legs protrude so that both legs of the fixing pin P-4 are pierced into the center hole when the fixing pin P-4 is fixed, Provide fixation.

The leaf spring 250 is given a repulsive force (elastic force) against bending such that the leading end of the leaf spring 250 is engaged with the engaging protrusion 120 divided by the body 210 of the band 100 by bending.

The leaf spring 250 is integrally formed at one side of the front portion 201 of the buckle body 210 and is bent to have an elastic force toward the rear portion 202. The end surface of the leaf spring 250 is connected to the divided engagement protrusions 120 of the band 100, The resilient supporting piece 252 is formed at the rear center of the engaging bent end 251 and the engaging bent end 251 on both sides.

A buckle switch 300 for blocking the movement of the latching protrusion 120 by separating or contacting the distal end of the leaf spring 250 accommodated in the buckle main body 210 from the body 110 of the band 100 Are provided on both side portions 203 and 204. [

The connecting portion 260 is bent at one side of the front portion 201 of the discharge port 230 of the buckle main body 210 to fold the fixing pin P-4 to be fixed to the adherend P- The fixing groove portion 261 is formed so as to be folded.

The buckle switch 300 is formed of a hinge knuckle 340 formed on both sides of the center by an axial pin 350 assembled to a shaft hole 206 penetrating both side portions 203 and 204 of the buckle main body 210, The hooking bent end 251 of the leaf spring 250 can be forcibly lifted by the rotation of the shaft and the hooking state can be released.

The buckle switch 300 has a pair of bending protruding ends 310 bendingly protruded from both sides of the front end of the buckle switch 300 so as to be hooked on both side locking protrusions 120 of the band 100.

The both bending protruding ends 310 of the buckle switch 300 are brought into close contact with the body 110 of the band 100 by the elastic receiving pieces 252 of the leaf spring 250 which are in press contact with the bending portions 320, The slide of the band 100 by the device 120 is interrupted.

In the present invention, the leaf spring 250 is bent at the center by the concave groove portion 253 through which the shaft pin 350 passes without interfering, and the buckle switch 300 is arranged so that the hinge knuckle 340 is engaged with the concave groove portion 253 And the pushing portion 330 of the buckle switch 300 is pushed by the elastic receiving piece 252 of the leaf spring 250 so that the pushing portion 330 of the buckle switch 300 is pushed by the insertion port 220, As shown in Fig.

The present invention can intermittently engage the engagement protrusion 120 of the band 100 by simultaneously engaging the bent end 251 of the leaf spring 250 and the bending protrusion 310 of the buckle switch 300.

The operation of the present invention will be described with reference to FIG.

In the description of the operation of the present invention, the direction in which the band 100 is tightened is referred to as a forward direction and the direction in which the band 100 is unwound is referred to as a reverse direction.

When the band 100 is tightened, it is pulled toward the discharge port 230 of the buckle main body 210 of the buckle 200. The pulling force of the band 100 is applied to the button switch 300 which has been pressed by the engaging bent ends 251 formed on the both ends of the plate spring 250 and the elastic support pieces 252 of the plate spring 250, So that the pressing force of the bending protrusion ends 310 on both sides of the engaging protrusion 120 is free to slide.

At this time, the band 100 is sewn to the adherend P-2 by the sewing groove 140 at the center, so that the sewing line is exposed to the maximum extent, and the slide protrusion 130 reaches the back surface 202 of the buckle body 210, Is guided by the guide slot 205 formed in the front side and the back side divided on both sides is slid in a close contact state.

Of course, the buckle main body 210 is provided in a state of being connected to the adherend P-1 by the connecting portion 260 of the buckle main body 210.

When the band 100 is pulled in the reverse direction, the engaging bent end 251 of the leaf spring 250 and the bending protruding end 310 of the button switch 300 are pushed by the inclination, The engagement protrusion 120 is inhibited from being released and the slide of the band 100 is blocked.

Therefore, when the band 100 is loosened, the pushing portion 330 of the buckle switch 300 is pressed to rotate around the shaft pin 350.

When the buckle switch 300 is rotated, the bending protrusion 310 is heard and the bending portion 320 pushes the elastic bending piece 252 of the leaf spring 250 and rotates to simultaneously receive the bending bending 251 The band 100 is released from the height of the latching protrusion 120 of the band 100 and is freely slid in the opposite direction to be released.

The embodiments according to the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the technical concept of the present invention.

For example, in the above-described embodiment, the leaf spring 250 integrally bending-formed on the buckle body 210 constituting the buckle 200 may be configured as a separate type as in Patent Document 1 of the applicant's prior art .
