BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt buckle,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a belt buckle capable of adjusting the length of a belt by adjusting a gap between a belt fixing hole and a buckle, and more particularly to a belt buckle capable of adjusting a length of a band so that a wearer can adapt to body changes To a belt buckle capable of adjusting the length of the belt by adjusting the interval between the belt fixing hole and the buckle.

Generally, a strap forms a ring or a projection which is pivotally coupled to a buckle by a combination of a buckle and a band, and a band is provided with a fixing band for fixing the band edge fixed to the combining hole punctured at a predetermined interval, And a hook type type which is capable of fastening the projecting portion to the engagement hole.

The problem of such a hook-type type is that there is a problem due to deformation or breakage of the strap such as stretching or tearing of the joining hole of the band to be fastened to the ring or the protrusion formed on the buckle for a long period of use, There is a problem that the length of the strap can not be finely adjusted to fit the human body according to the change of the strap and that the wearer has to drill a separate hole if the strap does not fit the perforated hole.

In addition, it is difficult to apply this fixed structure in response to immediate change when there is a case in which the previously fitted joint state has to be tightened or loosened according to the situation or body change in daily life.

In order to solve such a conventional problem, a sliding type buckle has been developed, which is a type in which a serrated pressing portion formed on a buckle is brought into close contact with a band to fix a strap. However, in the case of this sliding type, As a result of repeated use, when the teeth of the pressing portion become dull, the band slips and the binding force gradually weakens, so that the belt is loosened even when the wearer's small body changes. In case of intense exercise, The pulleys are closed.

Accordingly, various belt buckles capable of solving such problems have been developed.

First, the Korean Registered Utility Model No. 20-0470117, 'the belt buckle capable of adjusting the length' is a hook or buckle used in the conventional buckle, that is, a hook type buckle and a sawtooth type, and a sliding type buckle for fixing the band by pressing the teeth So that the length of the strap can be adjusted so that the wearer can adapt to the change of the body, and at the same time, the phenomenon that the strap naturally loosens can be prevented from occurring, To a belt buckle capable of adjusting the length of the buckle to prevent the loosening phenomenon.

Such a buckle is capable of adjusting the length of the belt so as to be adaptable to the body change of the wearer. However, since the buckle can be moved only to the designated position, fine adjustment is difficult.

Also, the Korean Registered Utility Model No. 20-0292972 'variable buckle' is characterized in that it can be conveniently used as a variable buckle for adjusting the length according to the change of abdomen pressure of the wearer. For this purpose, The buckle includes a waist band and a buckle.

FIG. 1 is a perspective view showing a basic configuration of a belt buckle 200 capable of adjusting the length of a belt by adjusting the interval between the belt fixing hole and the buckle according to the present invention, FIG. 2 is a perspective view FIG. 3 is a perspective view showing the structure of the coupling portion between the buckle 200 and the band 100 in the belt buckle 200 in which the length of the belt can be adjusted. And FIG.

1 and 2, a belt buckle 200 capable of adjusting the length of a belt by adjusting the distance between the belt fixing hole and the buckle according to the present invention comprises a band (not shown) having a plurality of fixing holes 110 The buckle 200 includes a base portion 210 and a base portion 210. The buckle 200 includes a base portion 210 and a base portion 210. The buckle 200 includes a base portion 210, A band insertion space 240 is formed in which the band 100 is inserted between the base portion 210 and the pair of wall portions 220, A slide groove 221 extending through the wall 220 in the longitudinal direction is formed and a hook 211 fastened to the fixing hole 110 is formed on one side of the side of the base 210 ) Is provided.

That is, the band 100 may be made of leather, synthetic resin, cloth, etc. Generally, the band 100 has a shape elongated so as to cover the waist of the wearer. At this time, a plurality of fixing holes 110 are formed in the surface of the band 100, and the fixing holes 110 may be formed at regular intervals along the extending direction of the band 100, but basically, It can be said that it is not necessary to form the fixing holes 110 on all the surfaces because it is the application for surrounding the waist.

Next, the configuration of the buckle 200 that can fix and fix the band 100 is further included. The buckle 200 basically includes a base portion 210, a pair of wall portions 220 standing on both sides of the base portion 210 and an upper portion 230 supported by the wall portion 220 A band insertion space 240 surrounded by the base part 210 and the upper part 230 and the pair of wall parts 220 is formed on the side of the base part 210. Further, And a hook 211 to be fastened to the fixing hole 110 formed in the upper end of the fixing hole 110 is provided. Therefore, the shape of the buckle 200 has a shape except for the front and rear faces of the cube, except for the hook 211. The buckle 200 allows the band 100 to be inserted from at least one side of the through- It is the most preferable structure that the first electrode 211 is located.

Further, the both wall portions 220 of the buckle 200 are each formed with a slide groove 221 extending through the longitudinal direction. Both ends of the pushing member 300 are inserted into the slide groove 221 and are coupled to move along the slide groove 221. The space between the pushing member 300 and the base portion 210 of the buckle 200 may be a size enough to allow the band 100 to enter and pass therethrough or a height substantially equal to the height of the band 100 So that the pushing member 300 can be pressed against the base portion 210 by pressing the band 100. As a result, Although not shown in the figure, the gap between the slide groove 221 and the base 210 may be wider than the band 100. In this case, (Not shown) which is branched and extended toward the upper surface of the pushing member 210 so that the surface of the band 100 can be pressed more easily when both ends of the pushing member 300 are fitted into the auxiliary groove Of course it is possible.

The belt buckle 200 further includes a pair of fastening portions 251 that are respectively seated on the upper and lower surfaces around the ends of the band 100 and fasteners 251, And a pushing member 253 formed of a pushing fixing part 253 which forms a seating space 254 of the pushing member 300 into which the pushing member 300 can be inserted by connecting ends of the fixing part 251, ). The band extender 250 is fixed to the pushing member 300 to fix the band 100 wherein the fastener 252 is preferably composed of a detachable bolt / So that it can be freely replaced. The band 100 can be replaced or adjusted and the fastener 252 can be tightened again by releasing the fastener 252 if the band 100 is to be deflected or to change the overall length of the band 100 .

As shown in FIG. 3, the band extender 250 has a structure in which a band coupling rod 255 is inserted into a pushing and fixing part 253 to be fixed between the wall parts 220 as shown in FIG. 3, It is possible for the pushing member 300 to be fitted to the pushing and fixing part 253 in place of the band coupling rod 255. 3 shows a structure in which the pushing member 300 is inserted into the slide groove 221 and the pushing member 300 presses the band elongated body 250 in a state where the band binding rod 255 is provided. 2, the pushing member 300 pushes the pushing member 300 directly into the pushing and fixing unit 253, as shown in FIG. In the case of FIG. 2, it is easy to integrate the components separately. In the case of FIG. 3, since the band connecting rod 255 is separately provided, the band extending body 250 is removed from the buckle 200 and is easily replaced . Here, the band coupling rod 255 is configured to prevent the band extension body 250 from escaping from the buckle 200. That is, when the pushing member 300 pushes the band extension body 250 or the band 100 to fix the position, the pushing member 300 has a shape of a rod having a width larger than the gap between the pushing member 300 and the base portion 210, The pushing member 300 can be prevented from being separated from the band extending body 250 or the band 100 by acting as a catching jaw. (Of course, if the pushing member 300 is pushed with a strong force, In the case of applying the force, the band extension member 250 is limited to the case where it is necessary to replace the band extension member 250. Accordingly, the band extension member 250 may not be considered much. Of course it is possible. However, when the band connecting rod 255 is used, when the band extending body 250 is pulled out from the band insertion space 240 of the buckle 200 at the maximum, the band connecting rod 255 can be seen to the outside The length of the upper portion 230 of the buckle 200 and the base may be longer than the length of the wall portion 220 so that the band connecting rod 255 may be somewhat shielded. Therefore, these two configurations are mutually exchangeable and can be selected as needed. However, the following description will be made with reference to the embodiment of FIG. 2, and it goes without saying that these configurations are all applicable to the embodiment of FIG.

As described in the title of the present invention, the adjustment of the distance between the fixing hole 110 and the fixing hole 110 formed in the band 100 means that the physical position of the fixing hole 110 formed in the band 100 is The band 100 is fixed at a specific position inside the buckle through the structure of the pushing member 300 and the band connecting rod 255 to adjust the exposed length of the band 100, The distance between the fixing hole 200 and the fixing hole 110 is different from that before.

4 is an exploded perspective view showing the basic structure of the pushing member 300. As shown in Fig.

When the band 100 is inserted into the band insertion space 240, the pushing member 300 is further inserted into the slide groove 221, The main bar 310 and the main bar 310 located between the pair of wall portions 220 are formed by pressing one side of the band 100 so that the engaging portion 630 can not pass therethrough. A pushing spring 330 inserted into the fitting groove 320 to provide elasticity and a pushing spring 330 inserted into the fitting groove 320 from the longitudinal direction ends of the main bar 310, A pushing portion 340 extended to be exposed to the outside of the buckle 200 in a state of being inserted into the fitting groove 320 and being slidably mounted along the slide groove 221, (Not shown) protruding from one side of the outer circumferential surface of the wall portion 220, And a packing part 350 for pressing the side surface of the main bar 310 to fix the main bar 310.

That is, this form has a thickness enough to allow the main bar 310 to press the surface of the band 100 in the same shape as a plunger, and a pushing part 340 protruding from both ends of the main bar 310, So that the pressing portion 340 can be moved along the slide groove 221. In this way, That is, the slide groove 221 is preferably configured to limit the movable section of the pushing member 300 in the band insertion space 240.

Each of the lengthwise ends of the main bar 310 is provided with a fitting groove 320 having a center portion. The push spring 330 and the pressing portion 340 are sequentially mounted on the fitting groove 320. Here, of course, the fitting groove 320 may be formed to penetrate both ends. The pressing portion 340 is provided with elasticity by the push spring 330 so that the pressing portion 340 can be lifted and lowered. One surface of the pressing portion 340 is pressed against the surface of the wall portion 220 on the side of the band insertion space 240, And a packing part 350 for fixing the position of the packing part 310. That is, the position of the main bar 310 is fixed by the close contact of the packing part 350. Therefore, by pressing the pressing part 340 to release the close contact of the packing part 350, So that it can be changed.

At this time, the following detailed structure may be further applied to the pressing portion 340 so as to increase the fixing force.

5 is an exploded perspective view showing an embodiment of the pushing member 300. FIG.

First, referring to FIG. 5 (a), a latching groove may be formed on the outer circumferential surface of the pressing part 340 at regular intervals. The slit 321 extends in the depth direction at one side of the inner circumferential surface of the fitting groove 320 and the slit 321 extends inwardly in the depth direction of the slit 321. [ And a receiving groove 322 inclinedly inclined toward the outside of the fitting groove 320. The pushing member 300 includes a base pin 361 that is vertically slidably inserted into the receiving groove 322 and a base pin 361 that is inserted into the receiving groove 322 upwardly inclined from one end of the base pin 361, And a protruding portion 362 which is bent and extended to be inserted into the engaging groove at the opposite end of the base pin 361 at the opposite end of the insertion inclined portion 363. The engaging pin 360 ). ≪ / RTI > At this time, the position of the engaging pin 360 is lower than the engaging groove in the initial state (the state in which the pressing portion 340 is raised).

The operation of such a configuration can be described in detail with reference to Fig. 5 (b). In the initial state, the pressing portion 340 is raised, and the protruding portion 362 is positioned in a state of being engaged with the engaging groove 341. When the lowering of the pressing portion 340 occurs, the protruding portion 362 and the engaging groove 341 are engaged with each other so that the engaging pin 360 is lowered so that the insertion inclined portion 363 of the engaging pin 360 is received And is inserted deeply into the groove 322. At this time, almost no space is left between the engaging pin 360 (precisely, the base pin 361) and the pressing portion 340, so that adhesion can be maintained. Further, when a further external force is applied to the pressing portion 340 and the pressing portion 340 is further lowered, the protruding portion 362 is detached from the engaging groove in correspondence thereto. However, the latching pins 360 are formed of a rigid material such as an iron core so that the latching pins 360 can be retained even in such a large number of releases and bindings, and the pressing portions 340 are made of elastic materials such as rubber and synthetic resin, But it is preferable that it is made of a material having sufficient strength. Or both of them may be made of a rigid material, but the hook 360 may be formed so as to have a thin thickness so that it can be concentrated only for the purpose of engaging and adhering it.

The pushing spring 340 pushes the pushing part 340 outward again due to the restoring force and the pushing part 340 pushes the packing part 350 toward the wall part 220, So that the protrusion 362 can be caught by the retaining groove 341 to be maintained in a fixed state.

At this time, preferably, when the protrusion 362 is hooked on the slit 321 by the latching groove 341 and the packing 350 touches the wall 220, when the pusher 340 protrudes at the maximum, It is needless to say that a pin fixing groove (not shown) may be further formed at a position where the end of the insertion slant part 363 of the insertion slant part 360 is positioned to assist in fixing the insertion slant part 363 easily. This allows the pushing member 300 to have a force that can be fixed at a designated position by further increasing the physical coupling / fixing configuration by further advancing the structure of the spring through only the elasticity of the spring.

As shown in FIG. 5C, the engaging pin 360 is provided with an engaging connecting portion 364 which is bent and extended toward the outside of the main bar 310 at one surface side of the engaging pin 360, And a hook fixing portion 365 extending and extending toward the hooking connection portion 364 of the hooking pin 360 located at the opposite end of the main bar 310 at the end of the main bar 310, The configuration of the elasticity fixing part 366 may be further included. The stopping connection portion 364 may be a stopper that contacts the upper surface of the main bar 310 (the periphery of the fitting groove 320) when the main bar 310 is lowered by a predetermined level or more, can do. Since the hook fixing part 365 extends parallel to the outer peripheral surface of the main bar 310, the hook connecting part 364 and the hook fixing part 365 are fitted into the main bar 310 . Therefore, it is possible to prevent the engaging pin 360 from entering too deeply along the slit 321. [ The resilient fixing portion 366 further extends at the end of the retaining portion 365 so as to extend to the outside of the main bar 310. The resilient fixing portion 366 presses the pressing portion 340 Even when the projecting portion 362 of the engaging pin 360 is released from the engaging groove 341 at the maximum while being pulled out of the groove 320 to the maximum and at the same time being slanted outwardly by the insertion inclined portion 363, The engaging pins 360 can be elastically supported by the engaging projections 366 without coming out of the slits 321.

6 is a longitudinal sectional view showing an embodiment in which a buffer material 214 is applied to the buckle 200. Fig.

At this time, the base portion 210 of the buckle 200 may further include a buffer member 214. The cushioning material 214 may be configured to provide a sufficient frictional force such that the band 100 can be fixed by pressing the band 100 from both sides together with the pushing member 300.

The cushioning body 214 includes a cushion body 212 of a stretchable material which presses the opposite side to which the pushing member 300 is closely attached to the band 100 and a cushion body 212 which is laminated on the upper surface of the cushion body 212, And a frictional surface 213 formed of a material having a friction coefficient larger than that of the surface. The cushion body 212 is preferably made of a flexible material such as a sponge or a memory foam so that the cushion body 212 is formed of a material capable of deforming its shape while allowing sufficient pressure to be applied thereto. A friction surface 213 formed of a material having a higher frictional coefficient than the cushion body 212 is formed on the upper surface of the cushion body 212 (for example, a shape processing such as forming a plurality of the clincher projections 540 on the surface A method of applying a coating material having a viscosity capable of raising the frictional force can be utilized), so that the band 100 is fixed by applying double pressure on both sides of the band 100.

At this time, a plurality of elastic protrusions 215 formed on the surface of the friction surface 213 may be formed on the friction surface 213 at regular intervals. The shape of the protrusion 215 includes a first inclined surface 216 extending upwardly inclined at a first inclination along a direction (longitudinal direction) in which the band 100 is inserted from one side of the surface of the friction surface 213, And a second inclined surface 217 extending downward at a second inclination greater than the first inclination from the end of the inclined surface 216 to the other side of the surface of the friction surface 213 along the direction in which the band 100 is inserted, The extension of the first inclined surface 216 is longer than the extension of the second inclined surface 217 so that the insertion of the band 100 is easily formed along the first inclined surface 216, The second inclined surface 217 is prevented from moving due to the large inclination angle of the second inclined surface 217 so that the band 100 is not easily separated from the second inclined surface 217. [

The cushion body 212 further includes a plurality of compartment openings 261 formed inwardly inwardly in contact with the virtual connecting lines extending vertically from the respective protrusions 215 toward the cushion body 212, (262) that is larger than the diameter of the inlet (261) to expand the inlet (261) at the end of the inlet (261).

That is, the extended part 262 is a space formed at regular intervals on the surface of the cushion body 212 through the receptacle opening 261, and is further provided with a material having a higher elasticity than the cushion body 212 A filler 263 made of a smaller volume than the expansion part 262 and accommodated in the expansion part 262 and an air gap layer 262 having air in the remaining space in which the filler 263 is accommodated in the expansion part 262. [ (264). The extension part 262 can increase the durability of the cushion body 212 through the filler 263 and thus extend the service life of the cushion body 212 compared to the conventional structure even if the projection 215 is continuously pressed down. It is possible to prevent the breakage of the filler 263 through the gap layer 264 between the filler 263 and the expanding part 262 and the breakage of the expanding part 262 by the filler 263 So that it is possible to form an effective cushion body 212 configuration. Here, the filler 263 may be formed in a triangular prism shape, a square pillar shape, or a polygonal prism shape larger than the triangular prism shape, so that even if the pillar 263 has a cylindrical shape when viewed from the outside, The present invention is not limited thereto.

As another configuration, when the main bar 310 assists the pressing of the band 100 and at the same time the band 100 desires to be removed from the band insertion space 240, The following configuration may be further included.

7 is a conceptual view showing an embodiment in which the clip 100 is applied to the clip 100. FIG. 8 is a view showing an embodiment in which the clip 100 is applied to the clip 100 using the clipper cover 600. FIG. It is a conceptual diagram.

7 is an exploded perspective view showing the detailed structure of the cleator cover 600, and will be described with reference to this. The main bar 310 further includes guide grooves 311 extended from at least one of the vertical grooves 310 to the outer side of the main bar 310 and extended obliquely. (342) protruded and extended to move along the guide groove (311) when the lifter body (340) is lifted or lowered. The push spring 330 is rotated along the guide groove 311 formed in the main bar 310 when an external force is applied to the push portion 340 so as to provide a restoring force by elasticity when the main bar 310 rotates, So that the pushing portion 340 is forcibly rotated or the main bar 310, which is in close contact with the band 100, is pushed and rotated.

The pushing member 300 is formed in a cylindrical shape and includes a clincher 500 having a bar insertion groove 510 penetrated to insert and fix the main bar 310 at a central portion thereof, A clevis cover 600 composed of a pair of depressing and fixing parts 251 fixed and a lid part 620 covering a part of the outer circumferential surface of the clincher 500 while connecting the pair of depressing parts 251, . That is, the clincher 500 is surrounded by the main bar 310 and rotatably mounted separately from the main bar 310. And a lid part 620 which is mounted on one side of the pressing part 340 and covers a part of the outer circumferential surface of the clincher 500 while connecting the pressing and fixing part 251, do. That is, the lid unit 620 can be said to be configured so as to be rotatable together with the pushing unit 340. Of course, as shown in the drawing, another clipper protrusion 540 may be further formed on the surface of the clincher 500 to increase the adhesion.

The clipper cover 600 further includes a latching portion 530 which is caught by the latching step 530 and pushes up the clipper 500. In addition, 630 are formed to rotate along the guide groove 311 located in the main bar 310 when the pressing portion 340 is pressed. At this time, the lid unit 620 can be rotated by the pressing and fixing unit 251 in the same manner.

8, the clicter 500 can be pushed up by engaging the engaging step 630 with the engaging step 530 when the lid part 620 is rotated The clipper 500 pushing the band 100 is pushed and moved by simply pressing the pusher 340 so that the fixed position of the band 100 can be adjusted by releasing the fixing of the band 100, And the like.

Although the belt buckle capable of adjusting the length of the belt by adjusting the distance between the belt fixing hole and the buckle according to the present invention has been described above and illustrated in the drawings, And various changes and modifications may be made without departing from the technical spirit of the present invention.
