Description

Belt retracting device and retracting method thereof

The present invention relates to a retracting device, and more particularly to an easy-to-operate belt retracting device and a method for retracting the same.

In recent years, in order to prevent the foot from being injured when sliding in the shoe during walking or exercising, the sports shoes particularly emphasize the adjustment of the tightness between the shoe body and the foot. In the past, in order to achieve this, a common way is, for example, through a shoelace. Elastic band, zipper or devil felt. However, the devil felt edge is easy to get the dust and dust, and it is easy to be fatigued after repeated tearing, and the utility is not good. The adjustment of the zipper is small and the fixing is poor. As for the elastic band, the weather resistance is not good, and it is easy to harden with time. Loss of function. Therefore, the sneakers on the market are still dominated by shoelaces.

However, for children who do not tie the laces, it is a common problem that the shoelaces are loosened due to poor binding. For the elderly who are physically weak, the action of tying the laces is often troublesome. Most importantly, in some more intense or special sports situations, such as basketball, tennis, rock climbing, skateboarding, etc., once the shoelace is loose or the shoelace remains too long, it is easy to move in the process of the foot. Causes a trip, or is smothered by foreign objects, and then sends It is dangerous, and this will be a great threat to the players who take the sport as their career.

When the clamping component 220 is positioned by the first limiting portion 411, the releasing unit 400 is regarded as being located at a first position, and the second bonding portion 430 is correspondingly engaged with the first bonding portion 320. When the clamping component 220 is positioned by the second limiting portion 413, the releasing unit 400 is regarded as being located at a second position, and the second bonding portion 430 is disengaged from the first bonding portion 320.

The interlocking member 500 is a hollow ring body. Four elastic supporting seats 510 are protruded at equal intervals in the hollow ring of the linking member 500. The elastic supporting seats 510 are extended along the hollow ring wall of the linking member 500 to form a bullet. Arm 520. The resilient arm 520 of the linkage 500 can be axially elastically reciprocally displaced corresponding to the outer ring 421 and the inner ring 431. Each of the latching arms 520 is integrally connected to the connecting member 500, and an outer end of each of the resilient arm 520 is provided with a sliding block 521 and a card end 522. Each of the card ends 522 provides a limit corresponding to the inner ring row 431. force. In a state in which the release unit 400 is not biased, each of the sliding blocks 521 substantially cooperates with the card end 522 to block an outer ring of teeth 421 from rotating in a releasing direction, and each of the sliding blocks 521 substantially cooperates with the card end 522. Blocking any of the outer ring teeth 421 to rotate in a tightening direction. The latching member 500 is further provided with a plurality of latching projections 530.

The inner ring row 431 has a stop slope 4311 and a release slope 4312, and the stop surface 4211 The orientation is opposite to the stop ramp 4311. Each of the sliding blocks 521 corresponds to each of the stopping faces 4211 by a plane 5211, and each of the card ends 522 corresponds to each of the stopping slopes 4311 and the respective releasing slopes 4312 by a bevel (not numbered).

Next, please refer to the partial perspective perspective view shown in FIG. 6 and the partial enlarged schematic view of the sliding resisting block 521 and the stop surface shown in FIG. 7 , and cooperate with the elastic arm 520 of FIG. 8 and FIG. State diagram and diagram of the barrier band release state. When the release unit 400 of the present invention is in a first position, each of the sliding blocks 521 substantially cooperate with the card end 522 to block an inner ring of teeth 431 from rotating in a release direction. Therefore, the user of the present invention can easily rotate the knob 420, and the belt receiving member 300 is pivoted on the locking component by a pivot hole 301 by the state in which the second joint portion 430 is coupled with the first joint portion 320. Outside of 220, the belt retracting member 300 is rotated, and the belt strap (not shown) is bundled in the annular rail 310. At this time, since each of the card end 522 is pushed by the release slopes 4312 to elastically deform the spring biasing arm 520, the spring biasing arm 520 does not affect the converging operation. When the operator releases the hand, since the sliding block 521 cooperates with the card end 522 to substantially block an inner ring row 431 from rotating in a releasing direction, the belt retracting member 300 does not freely rotate to loosen the band strap.

In the state in which the release unit 400 is rotatively biased toward the release direction, as shown in FIG. 8 , each of the sliding contact blocks 521 originally engages the card end 522 to block an outer ring row tooth 421 from rotating in a release direction, but the release unit 400 is oriented. The release direction is urging the rotation, so that each of the sliding blocks 521 is offset by the inclined surface 5212 corresponding to the outer ring teeth 421 and the inclined surface 4212; at this time, the sliding block 521 uses the two inclined surfaces 4212 and 5212 to generate downward force to cause the elastic force. Arm 520 elastic The deformation is further caused by each of the card ends 522 coming out of the respective stop slopes 4311. At this time, each of the slipping blocks 521 substantially cooperates with the card end 522 to perform a segment-by-segment release (tooth-by-teeth) operation, so that the band strap is controllably released toward a release direction.

Then, when the user wants to completely release the belt strap, the knob 420 can be pulled up in the axial direction, so that the claw portion of the engaging component 220 obtains an axial pre-force and then passes through the temporary sliding portion 412, thereby making the card The component 220 is switched by the first limiting portion 411 to the second limiting portion 413. When the clamping component 220 is positioned by the second limiting portion 413, the release unit 400 is considered to be in a second position, and the second bonding portion 430 is disengaged from the first bonding portion 320. It is worth mentioning that, since each card end 522 correspondingly cooperates with an inner ring row tooth 431 to provide a limiting force, the limiting force can effectively prevent accidental release or operation accident, and can also make the clamping component 220 have the first limit. When the position portion 411 is switched to the second limiting portion 413, it is not affected by the excessive reaction force of the release reaction force. Therefore, the present invention can use the foregoing design to allow the operation process to have a limit position and a buffering limit force.

After the clamping component 220 is switched from the first limiting portion 411 to the second limiting portion 413, the release unit 400 of the present invention is considered to be in a second position, and the second bonding portion 430 is disengaged from the first bonding portion 320. At this time, the belt retracting member 300 can freely rotate (infinite position force), and the belt belt body can be freely released from the endless rail 310.

Therefore, the present invention provides a method for retracting and tying a belt strap with a belt retracting device 100. The method of the present invention includes the step of operating the release unit 400 in a first position. Rotating the release unit 400 to rotate the release unit 400 relative to the linking member 500 in the releasing direction, and the belt retracting member 300 is interlocked by the releasing unit 400 to surround the belt strap. Track 310 is rolled up. The operation release unit 400 is located at the second position. Finally, the force of the belt strap causes the belt retracting member 300 to freely rotate to release the belt strap.

Please refer to still another embodiment of the structural aspect of the present invention in Figs. 10 to 15. 10 is a perspective view of the combined appearance; 11 and 12 are respectively exploded perspective views in different directions; and FIGS. 13 and 14 illustrate the release unit 630 in the first position and the second position.

And the temporary sliding portion 6313 allows the clamping member 613 to pass a pre-force.

The linking member 640 is rotatably positioned in the accommodating space 612. The linking member 640 has a second connecting portion 642 having a ring-shaped shape, and the linking member 640 has a plurality of corresponding base ring teeth 611 and release ring teeth 6321. When the locking member 613 is positioned by the first limiting portion 6311, the releasing unit 630 is located at a first position, and the second coupling portion 642 is correspondingly coupled to the first coupling portion 622. The resilient arm 641 is engaged with the base ring gear 611, and the spring resisting arm 641 can be elastically contracted in the tightening direction by the radial direction of the release ring gear 6311. Therefore, the buckling arm 641 substantially blocks the release unit 630 from rotating in a release direction, and the bounce arm 641 does not substantially block the release unit 630 from rotating in a tightening direction. When the other clamping component 613 is positioned by the second limiting portion 6312, the releasing unit 630 is located at a second position, and the second bonding portion 642 is separated from the first bonding portion 622.
