Abstract
The invention discloses a belt length automatic adjusting device which is developed for automatically extending and contracting the belt length when the abdomen is inflated due to overeating or sports so as to eliminate the oppressive feeling applied to the abdomen by a user during breathing.
Description
Technical Field
The present invention relates to an automatic belt length adjusting apparatus, and more particularly to an automatic belt length adjusting apparatus which: can eliminate the oppression feeling to the abdomen caused by the automatic extension and contraction of the belt length when the abdomen is expanded and contracted due to overeating or sports.
Background
In general, when a user wears a belt, the user is inconvenienced by pressure applied to the abdomen when the user changes a standing posture to a sitting posture or the abdomen is inflated due to overeating or exercise. In the case of the more serious, the digestive function is deteriorated due to the oppression feeling, and the durability of the belt is remarkably shortened.
Therefore, when applying pressure to the abdomen, the user needs to loosen the belt one by one to readjust the length, but there is a problem in that it is not possible to provide the user with convenience.
Therefore, a technology for automatically adjusting the length of the belt is being developed recently. For example, korean patent laid-open No. 10-1304007 discloses an apparatus for automatically adjusting the length of a belt.
However, the apparatus for automatically adjusting the length of the belt disclosed in the above patent has a disadvantage that the elasticity of the spring is weak and the functions of pushing and restoring the fixing clip are poor because the spring having a small diameter is used because the installation space of the frame is narrow. Further, the spring has a weak elastic force, and the expansion and contraction function of the spring is easily deteriorated due to the infinite repetition of the contraction and expansion, which causes a problem that the spring cannot be used for a long period of time. In addition, in modern industries where design is important, it is difficult to change the design.

Detailed Description
The present invention is described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the automatic adjusting apparatus for a length of a belt according to the present invention includes: the buckle connection member 100, the spring member 200, the length adjustment member 300, the cover member 400, and the buckle hooking member 500.
First, the snap coupling member 100 has a structure in which a sliding space 120 is formed at a lower portion of the base plate 110, both sides of the sliding space 120 are closed by side walls 130, a front surface is closed by a front wall 140, and a rear surface and a lower surface are open. Further, a snap locking piece 150 is formed on a front surface of the snap connection member 100, and the snap locking piece 150 is bent and extended from an end of the bottom plate 110 to the front surface, and a snap insertion space 152 opened downward is formed therein. Further, spring coupling rods 160 protruding downward are formed at both sides of the front surface of the sliding space 120, and a screw fastening boss 170 having a fastening hole 172 protrudes downward at the rear surface of the sliding space 120. Further, rail walls 180 protruding downward are formed on both sides of the sliding space 120, and rail grooves 182 are formed in the middle of the rail walls 180 in the front-rear direction. A cover placing groove 132 for placing the cover member 400 is formed in an inner surface of an end portion of the side wall 130 of the sliding space 120, and a hook insertion groove 134 into which the hook member 500 is inserted is formed in a portion of an outer surface of the side wall 130.
Next, the spring member 200 includes: a coil-shaped snap-in coupling part 210, a first support part 220 extending from one portion of the snap-in coupling part 210, a second support part 230 extending from the other portion of the snap-in coupling part 210, and a vertical support part 240 extending in a lower direction from an end of the second support part 230. In this case, an angle between the first and second support parts 220 and 230 is an obtuse angle. In addition, in the assembly, in a state where the spring coupling rod 160 of the snap coupling member 100 is snap-coupled to the snap coupling portion 210, the first support portion 220 is drawn into the sliding space 120 and closely attached to the side wall 130 so as to support the first support portion 220 and the sliding space 120 not to be drawn apart, and the second support portion 230 and the vertical support portion 240 are drawn into the sliding space and closely attached to the front wall so as to support the second support portion 230 and the vertical support portion 240 and the sliding space 120 not to be drawn apart.
Next, the length adjustment member 300 includes: a sliding part 310 inserted into a lower surface of the sliding space 120 and provided to be movable forward and backward along the sliding space 120; and a band connection part 320 integrally formed at one side of the sliding part 310 and provided to be closely attached to the rear surface of the snap connection member 100.
A locking groove 314 is formed in front of the sliding portion 310 so that a locking portion 312 is formed at the front end. The locking groove 314 may be formed by piercing a part of the front of the sliding portion 310, or may be formed in a space between the end of the sliding portion 310 and the locking portion 312 formed when the locking portion 312 extends from one end of the sliding portion 310 to the front and is bent at a right angle. With this configuration, when the sliding portion 310 is inserted into the sliding space 120, the end of the vertical support portion 240 of the spring member 200 is brought into close contact with the locking portion 312 by the locking groove 314. In this case, when the sliding portion 310 is moved backward by an external force due to a phenomenon such as the expansion of the abdomen of the user, the locking portion 312 pushes the vertical support portion 240 backward to move the vertical support portion 240 together, and when the force for moving the sliding portion 310 backward is released, the sliding portion 310 is automatically moved forward by the restoring force of the vertical support portion 240. An open groove 316 is formed to penetrate behind the sliding portion 310 so that the screw fastening boss 170 can be exposed. Further, since the rail protrusion 318 is formed to protrude from the upper surface of the sliding portion 310, the sliding portion 310 can stably move when moving forward and backward, and the rail protrusion 318 is inserted into the rail groove 182 and moves along the rail groove 182.
Next, a tape insertion space 322 into which an end portion of the tape 20 is inserted is formed in the tape connecting portion 320, and a tape fixing member 324 having a plurality of tape fixing protrusions 326 is rotatably provided around a rotating shaft 328 in the tape insertion space 322. Therefore, in a state where the end portion of the band 20 is inserted into the band insertion space 322, the band fixing member 324 is rotated to fit the band fixing projection 326 into the band 20, and the band fixing projection 326 and the band 20 are fixed so as not to be separated from each other.
Next, the cover member 400 is stacked on the lower surface of the snap connection member 100. That is, the lid member 400 is placed on the lid placement groove 132 and is not protruded downward, a through hole 402 corresponding to the fastening hole 172 of the screw fastening boss 170 is formed in the lid member 400, and the lid member 400 is fixed by the screw S fastened to the fastening hole 172 through the through hole 402. Further, a sealing plate 410 is integrally formed on the front surface of the cover member 400, and when the cover member is assembled so that the connection portion 12 of the buckle 10 is fitted into the buckle insertion space 152, the sealing plate 410 seals the lower surface of the buckle insertion space 152 so that the connection portion 12 of the buckle 10 is coupled into the buckle insertion space 152.
Next, the buckle hooking member 500 is fixed to a part of the cover member 400, and is provided to protrude toward the upper portion of the snap connection member 100, and a buckle insertion hole 502 is formed between the buckle hooking member 500 and the snap connection member 100. The buckle hooking member 500 is fixed to a part of the cover member 400 by protruding a pin coupling part 420 so that a coupling hole 422 is formed through a part of the lower surface of the cover member 400, a pin hole 510 corresponding to the pin coupling hole 422 is formed through an end of the buckle hooking member 500, and the buckle hooking member is fixed by the pin hole 510 and an assembly pin 520 that can be coupled through the pin coupling part 420. The buckle hooking member 500 is inserted into the hook insertion groove 134 of the buckle connection member 100 so as not to move forward and backward after installation.
On the other hand, the insertion guide groove 142 is formed at an inner corner portion of the front wall 140 of the snap connection member 100, and when the vertical support portion 240 of the spring member 200 is closely attached to the front wall 140, an end portion of the vertical support portion 240 is preferably exposed to the insertion guide groove 142. This is because when the sliding portion 310 is inserted into the lower surface of the sliding space 120, the end of the vertical support portion 240 is easily inserted into the locking groove 314 to maintain the state of being locked to the locking portion 312. That is, if the guide groove 142 is not inserted, the vertical support 240 is closely attached to the front wall 140, and thus, when the sliding portion 310 is assembled, the end of the vertical support 240 needs to be pulled by another tool and then inserted into the locking groove 314, and if the guide groove 142 is inserted, the end of the vertical support 240 can be kept in a state of being separated from the front wall 140, and thus, the end of the vertical support 240 can be easily inserted into the locking groove 314.
On the other hand, it is preferable that the roller member 250 is rotatably inserted into the vertical support portion 240 of the spring member 200, and when the vertical support portion 240 is locked to the locking portion 312 of the slide portion 310 and moves forward and backward, the surface of the roller member 250 in contact with the locking portion 312 changes while the roller member 250 is freely rotated. This allows the force to be dispersed when the locking portion 312 presses and presses the vertical support portion 240, thereby preventing the pressure from being applied to the same position all the time, and extending the life of the vertical support portion 240 to the maximum.
Next, the assembly and operational relationship of the automatic belt length adjusting device having the above-described structure will be described.
In assembling the automatic belt length adjusting apparatus according to the present invention, the spring member 200 is first inserted into the spring coupling bar 160 of the snap coupling member 100 to be assembled. That is, in a state where the spring coupling rod 160 is snap-coupled to the snap-coupling portion 210, the first support portion 220 is drawn into the sliding space 120 and closely attached to the side wall 130, and the second support portion 230 and the vertical support portion 240 are drawn into the sliding space 120 and closely attached to the front wall 140. Next, the sliding portion 310 is inserted into the lower surface of the sliding space 120 of the snap connection member 100 and assembled. In this case, the roller member 250 is provided so as to be locked to the locking portion 312 of the sliding portion 310 together with the vertical support portion 240 of the spring member 200, and so as to provide an elastic force so that the sliding portion 310 faces the front surface. Next, after the cover member 400 is covered with the snap-in connector 100 to cover the sliding portion 310, the screw S is fastened to the through hole 402 of the cover member 400 and the fastening hole 172 of the snap-in connector 100 to fix the cover member 400. Next, the buckle hooking member 500 is fixed to the cover member 400 by the assembly pin 520. In this case, the cover member 400 is covered and coupled in a state where the connection portion 12 of the buckle 10 is inserted into the buckle insertion space 152 of the buckle connection member 100. Then, the assembly is completed by connecting and coupling the band 20 to the band connection portion 320.
In the automatic belt length adjusting apparatus assembled as described above, the sliding portion 310 is assembled to be slidable back and forth in the sliding space 120, and thus the length of the belt can be automatically adjusted by moving back and forth toward the length adjusting member 300 according to the state and posture of the abdomen of the user. That is, as shown in fig. 3, when the user wears the belt, the user has an abdominal distention due to overeating or a feeling of pressure applied to the abdominal region due to sudden change from a sitting posture to a sitting posture, as can be seen from fig. 1 and 4, the length of the belt is automatically adjusted by the force of the length adjusting member 300 being spaced from the engaging member 100 by T. Thus, convenience and comfort can be provided to the user. As can be understood from fig. 1 and 3, when the oppressive feeling of the abdomen is removed by digesting or improving the posture, the length adjustment member 300 automatically comes into close contact with the buckle connection member 100 again by the restoring force of the spring member 200 to fix the trousers, thereby preventing the trousers from slipping down.
While the present invention has been particularly shown and described with reference to the foregoing embodiments, it will be readily appreciated by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
