Technical Field

[0001] This invention relates to the field of shoe technology, and more specifically to a laceless shoe. Background Technology

[0002] Shoes provide support and protection for the feet during walking or exercise, and are an indispensable part of daily life. For example, Chinese utility model patent application number CN202422625328.4 discloses a casual sports shoe, including: an upper with laces and a tongue; a sole at the bottom of the upper; a puncture-resistant part in the sole; several anti-slip protrusions evenly spaced along the outer contour of the sole, with an inclined surface at the inner end of each protrusion; and suction cups on the inclined surface, with suction cup grooves at their ends that contact the ground; wherein the inner surface of the suction cup groove is spherical. When wearing these shoes, you first place your foot inside the shoe, then pull the shoelaces to tighten them, and then cross and knot the shoelaces to tighten them and improve the fit of the shoes. However, in actual use, this way of tightening shoelaces is rather cumbersome. In addition, some people do not like to tie shoelaces, and a few people do not know how to tie shoelaces. These shoes with shoelaces will cause trouble for these groups of people. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a shoe without shoelaces that is more versatile.

[0004] Therefore, the present invention is implemented using the following technical solution: A laceless shoe includes an upper and a sole.

Pulling the pull button can disengage the pawl from the ratchet. Two second cables that can be wound around the rotating shaft are provided at the left and right ends. The left and right sides of the housing are respectively provided with second through holes through which the corresponding second cables pass. The second cables pass through the second through holes and are fixed to the rear end of the corresponding positioning slide.

[0006] Furthermore, a first spring seat is embedded in the middle of the upper end of the pawl, and a second spring seat aligned with the first spring seat is embedded in the housing. The second spring seat and the first spring seat are provided with spring grooves aligned with each other, and the spring is located between the two spring grooves.

[0007] Furthermore, the housing and the cover are detachably connected by multiple bolts, and a ball bearing is provided between the cover and the rotating shaft. The outer ring of the ball bearing is fixed to the cover, and the inner ring is fixed to the rotating shaft. The knob and pull button are both provided with anti-slip texture on their outer surfaces.

[0008] Furthermore, the shoe upper includes an inner shoe upper and an outer shoe upper bonded together. A U-shaped plate is provided between the inner shoe upper and the outer shoe upper at the heel of the shoe upper. Multiple positioning strips protruding from the outer shoe upper are provided on the left and right sides of the U-shaped plate. The positioning strips are provided with strip-shaped positioning grooves. The positioning slide is provided with a slide bar that is inserted into the strip-shaped positioning groove and can slide in the strip-shaped positioning groove.

[0009] Furthermore, the rear side of the U-shaped plate is provided with a support piece that extends through the outer shoe upper to support the shell. Both sides of the support piece are provided with buckles that extend through the outer shoe upper on the U-shaped plates, and the shell is provided with buckle holes that engage with the buckles.

[0010] Furthermore, the outer shoe surface is bonded with a wear-resistant strip that allows the second cable to be placed and slid, and the wear-resistant strip is provided with a groove for placing the second cable.

[0011] Furthermore, a wear-resistant sleeve is bonded inside the second through hole to allow the second cable to pass through.

[0012] Furthermore, a guide block is bonded to the outer surface of the shoe upper, and the guide block is provided with a guide hole for the elastic band to pass through.

[0013] Furthermore, the shoe opening and the opening are edged.

A pawl 14, which can engage with the ratchet 12, is hinged to the support 13. A spring 15 is provided between the pawl 14 and the housing 8 to cause the pawl 14 to press against the ratchet 12. A first cable 16 is provided on the outer side of the pawl 14. The housing 8 has a first through hole 17 through which the first cable 16 passes. A pull button 18 is fixed to the outer end of the cable. Pulling the pull button 18 disengages the pawl 14 from the ratchet 12. Two second cables 19, which can be wound around the rotating shaft 10, are provided at the left and right ends of the rotating shaft 10. Corresponding second cables 19 are provided on the left and right sides of the housing 8. The second through hole 20 is through which the second cable 19 passes and is fixed to the rear end of the corresponding positioning slide 6. The upper middle part of the pawl 14 is embedded with a first spring seat 21. The housing 8 is embedded with a second spring seat 22 aligned with the first spring seat 21. The second spring seat 22 and the first spring seat 21 are provided with spring grooves 23 aligned with each other. The spring 15 is located between the two spring grooves 23. The housing 8 and the cover 9 are detachably connected by multiple bolts 24. A ball bearing is provided between the cover 9 and the rotating shaft 10. The outer ring of the ball bearing is fixed to the cover 9 and the inner ring is fixed to the rotating shaft 10. The outer surfaces of the knob 11 and the pull button 18 are both provided with anti-slip textures 25. A wear-resistant sleeve 36 for the second cable 19 to pass through is bonded in the second through hole 20.

[0020] Reference Figure 1 and Figure 4As shown, the shoe upper 1 includes an inner shoe upper 26 and an outer shoe upper 27 bonded together. A U-shaped plate 28 is provided between the inner shoe upper 26 and the outer shoe upper 27 at the heel of the shoe upper 1. Multiple positioning strips 29 protruding from the outer shoe upper 27 are provided on the left and right sides of the U-shaped plate 28. The positioning strips 29 are provided with strip-shaped positioning grooves 30. The positioning slide 6 is provided with a slide strip 31 that is inserted into the strip-shaped positioning grooves 30 and can slide within the strip-shaped positioning grooves 30. The rear side of the U-shaped plate 28 has a protrusion of the outer shoe upper 27. The support plate 32 is used to support the shell 8. The U-shaped plates 28 on both sides of the support plate 32 are provided with buckles 33 that pass through the outer shoe upper 27. The shell 8 is provided with buckle holes 34 that are fastened to the buckles 33. The outer shoe upper 27 is bonded with a wear-resistant strip 35 that accommodates the placement and sliding of the second pull cable 19. The wear-resistant strip 35 is provided with a groove for the placement of the second pull cable 19. The outer shoe upper 27 is bonded with a guide block 37. The guide block 37 is provided with a guide through hole 38 for the elastic band 5 to pass through.

[0021] The working principle of this invention is as follows: When putting on the shoes, insert your foot into the shoe opening 3 and place it inside the shoe. Then, turn the knob 11 counterclockwise. The knob 11 drives the shaft 10 and ratchet 12 to rotate counterclockwise, causing the second cable 19 to gradually wrap around the shaft 10. The positioning slide 6 is pulled backward by the second cable 19, gradually tightening the elastic band 5, causing the opening 4 to close, so that the shoe upper 1 fits the wearer's foot. When taking off the shoes, pull the button 18 to disengage the pawl 14 from the ratchet 12. Under the elasticity of the elastic band 5, the positioning slide 6 will move forward, and at the same time, the opening 4 will expand, making it easier for the foot to come out of the shoe opening 3. Then, release the button 18, and the pawl 14 will return to its original position under the elasticity of the spring 15. During this process, the positioning slide 6 drives the second cable 19 to move and release the shaft 10, causing the shaft 10 to rotate clockwise.

[0022] In this embodiment, elastic bands 5 are crosswise arranged above the opening 4. A positioning slider 6 is connected to the rear end of each elastic band 5. The adjusting mechanism 7 drives the positioning slider 6 to slide, tightening or loosening the two crosswise elastic bands 5, causing the opening 4 to contract or expand, allowing the shoe upper 1 to fit the wearer's foot. By using elastic bands 5 instead of shoelaces, shoelaces are eliminated, making the adjustment method simple and efficient. Furthermore, it is suitable for people who dislike or cannot tie shoelaces, making it more versatile. The detachable structure of the shell 8 and the cover 9 facilitates the assembly of the adjusting mechanism 7. And subsequent maintenance; the setting of the first spring seat 21, the second spring seat 22 and the spring groove 23 makes the structure of the spring 15 more stable and prevents the spring 15 from falling off; the setting of the ball bearing makes the rotation of the shaft 10 smoother and avoids wear between the shaft 10 and the cover 9; the setting of the anti-slip texture 25 increases the friction of the knob 11 and the pull button 18, which is beneficial to the operation of the knob 11 and the pull button 18; the U-shaped plate 28 is set between the inner shoe upper 26 and the outer shoe upper 27 and is hidden, which not only provides better support for the heel, but also makes the shoe The design is more aesthetically pleasing. The combination of positioning strip 29, strip positioning groove 30, and sliding strip 31 allows the positioning slide 6 to slide only forward or backward, improving the structural stability of the positioning slide 6 and preventing it from moving randomly on the shoe upper 1. The support plate 32 supports the shell 8. The adjustment mechanism 7 is detachable by engaging with the buckle 33 on the U-shaped plate 28 through the buckle hole 34. The second pull cable 19 can be tied to the positioning slide 6 (the positioning slide 6 is provided with a tying hole or tying post). The wear-resistant strip 35 can prevent the second pull cable 19 from wearing down the outer shoe upper when it moves back and forth. 27. The groove design prevents the second pull cable 19 from detaching from the wear-resistant strip 35; the wear-resistant sleeve 36 prevents the second pull cable 19 from abrading the housing 8; the guide block 37 and guide through hole 38 provide guidance and positioning for the elastic band 5, preventing the elastic band 5 from moving up and down and detaching from the opening 4; the edging 39 not only covers the double-layer shoe upper 1 (inner shoe upper 26 and outer shoe upper 27), making the shoe more beautiful, but also makes the shoe opening 3 and opening 4 more comfortable, preventing the outer ends of the inner shoe upper 26 and outer shoe upper 27 from rubbing against the wearer's feet.
