Description

Technical Field

[0001] This invention relates to the field of athletic shoes, specifically to an athletic shoe with adjustable laces. Background Technology

[0002] Sports shoes are shoes worn by people when engaging in sports. With the popularization of sports and people's love for sports, the requirements for sports shoes in terms of comfort, protection, appearance and sports function are also getting higher and higher.

[0003] Existing athletic shoes use shoelaces to adjust the volume of the upper to accommodate different foot shapes for the same foot length. The shoelaces are tightened to secure the athletic shoe. Due to the inconvenience of tying shoelaces, there are alternative solutions using knobs and threads to replace traditional shoelaces. However, due to the limitations of shoe size, the thread winding method requires a sufficiently small thread diameter to reduce the total diameter of the coiled thread, which makes the thread prone to breakage. The small contact area between the thread and the shoe upper makes it easy to wear down the upper and cause the foot to feel constricted. Although it is more convenient to use than traditional shoelaces, its durability and experience are not as good as traditional shoelaces. Therefore, it is necessary to design an athletic shoe that is easy to adjust and tie. Summary of the Invention

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figure 1-8 The present invention provides a technical solution: an adjustable shoelace athletic shoe, comprising an outsole 1, a midsole 2, a tongue 6, an upper 5, and shoelaces 6, as shown below. Figure 1 As shown, a shoelace 6 is threaded through the front of the shoe upper 5. The shoelace 6 can adjust the volume of the shoe upper 5. A lacing assembly 7 is fixed on the shoe tongue 6. The end of the shoelace 6 can be fixed inside the lacing assembly 7. "V" shaped notches 8 are opened on both sides of the shoe upper 5. An elastic band 9 is fixed inside the "V" shaped notch 8. The elastic band 9 can protect the skin. A quick-release assembly 10 is fixed on the toe side of the "V" shaped notch 8. A rope 11 is fixed on the heel side of the "V" shaped notch 8. The quick-release assembly 10 can tighten the rope 11. The shoelaces can be easily tightened through the lacing assembly 7. The force is evenly distributed and the durability is good. The opening of the sports shoe can be adjusted through the quick-release assembly 10, making it easy to put on and take off. The operation is convenient.

[0015] To enable quick tightening of shoelaces and prevent them from coming loose, a lacing assembly 7 is used, including a housing A 12, a slider 14, and a handle 16. The housing A 12 is fixed to the shoe tongue 6, and a lacing channel 13 is opened inside the housing A 12. The shoelace 6 is inserted into the housing A 12 from the side and exits from the front. The slider 14 is slidably disposed inside the housing A 12. A spring 15 is disposed between the slider 14 and the housing A 12. In the free state, the spring 15 keeps the slider 14 inserted into the lacing channel 13. A handle 16 is fixed to the outer end of the slider 14.

[0016] The handle 16 is made of a flexible material, such as nylon strap, which is long enough to accommodate one or two fingers. After adjusting the shoelace length according to the foot shape, the excess shoelaces can be quickly secured by the lacing assembly.

[0017] To facilitate quick on and off of the shoes, a quick-release assembly 10 is used, comprising a B-shell 17, a ratchet 18, a pawl 20, and a shaped spring 22. The B-shell 17 is fixed to the shoe upper 5. The ratchet 18 is rotatably mounted inside the B-shell 17. A slot 19 is formed on the ratchet 18 to secure the rope 11. The pawl 20 is rotatably mounted inside the B-shell 17. A lever 21 is fixed to the outside of the pawl 20. A shaped spring 22 is fixed between the pawl 20 and the B-shell 17. The shaped spring 22 is made of spring steel and machined into an "n" shape. The inner surface shape is adapted to the shape of the pawl 20, and the outer surface shape is adapted to the shape of the B-shell 17. The inner surface of the shaped spring 22 contacts the pawl 24, and the outer surface contacts the B-shell 21. In its free state, the shaped spring 22 keeps the pawl 20 pressing against the ratchet 18, and the ratchet 18 can rotate clockwise in one direction only.

[0018] Outsole 1 and midsole 2 are made of materials with different elasticity. Outsole 1 can be made of rubber and midsole 2 can be made of thermoplastic polyurethane. Multiple massage protrusions 3 are fixed on the upper surface of outsole 1. The massage protrusions 3 pass through midsole 1 and contact the sole of the foot. The position of massage protrusions 3 is adapted to the acupoints on the sole of the foot. When walking, the sole of the shoe is subjected to friction. The outsole 1 and midsole 2 deform differently. Since the massage protrusions 3 are fixed on outsole 1, they move under the difference in deformation, which plays a role in massaging the sole of the foot.

[0019] The working principle of this invention is as follows: Adjust the shoelace length according to the foot shape, pull the handle 16 to drive the slider 14 to rise, tighten the excess shoelace 5, release the handle 16, and under the action of the spring 15, the slider 14 presses the shoelace 5 tightly, and the shoelace 5 cannot move; rotate the ratchet 18 to drive the slot 19 to rotate, the rope 11 tightens the "V" shaped notch 8, and the shoe upper 4 tightly wraps the foot. Since the pawl 20 is pressed by the irregular spring 22, the ratchet 18 cannot reverse. Move the lever 21 to make the pawl 20 flip outward, the ratchet 18 rotates freely, and the foot exerts force to open the "V" shaped notch 8 and the shoe can be taken off.

[0020] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
