Description

Technical Field

[0001] This utility model relates to the field of shoe accessories technology, specifically to a lace-free shoe buckle and a shoe. Background Technology

[0002] No-tie shoelace buckles are a type of shoelace that uses mechanical, elastic, or magnetic structures to lock shoelaces, replacing the traditional method of tying shoelaces by hand. By simplifying the process of putting on and taking off shoes, improving the anti-slip ability of shoelaces, and preventing shoelaces from coming loose during use, they enhance the convenience of wearing shoes and the aesthetics of matching shoelaces with shoes. By redesigning shoe accessories, they meet the needs of both ease of use and aesthetic appeal. With the changes in modern life, the demand for no-tie shoelace buckles is constantly increasing in both athletic shoes and everyday shoes. Existing no-tie shoelace buckles use a rotating structure or a drawstring structure. Rotary laces can avoid the risk of tripping due to loose laces and meet the need for quick removal, but for everyday footwear, they are difficult to adjust accurately in terms of tightness, making it difficult to fine-tune the lace locking force, which can easily lead to pressure on the foot or excessive force causing slippage. On the other hand, the plastic parts of the cord buckle structure are prone to aging and breakage, and the metal springs used are prone to aging and failure after long-term use. They also have the problem of inconvenient lace tightness adjustment, thus affecting wearing comfort. Therefore, there is a need for a non-slip, easy-to-adjust cord tightness, and aesthetically pleasing no-lace buckle that can be attached to shoes. Utility Model Content

[0003] One of the purposes of this utility model is to provide a no-tie shoelace buckle that solves the problems of insufficient anti-slip strength and difficulty in adjusting the tightness of existing no-tie shoelace buckles.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0005] A no-lace shoelace buckle includes a main frame with a through-hole and at least two ribs. Each rib is connected at both ends to opposite side walls of the through-hole, dividing the through-hole into at least a first through-groove, a second through-groove, and a third through-groove. Several anti-slip protrusions are provided on the ribs, spaced apart along their length, with adjacent protrusions forming a channel for the shoelace to pass through. The main frame extends outward from one side wall along the length of the ribs to form a locking frame with a locking groove. After the shoelace enters the through-hole, it wraps around the ribs along the channel. The ribs are pressed together to provide friction for securing the shoelace. The end of the shoelace is then inserted into the locking groove for fixation, preventing the end from shifting and causing the shoelace to loosen, thus facilitating subsequent adjustment of the shoelace tension.

[0006] Furthermore, secondary frames are provided on both sides of the main frame. The secondary frames are bent upward so that the end face of the secondary frame is higher than the upper end face of the main frame. The secondary frames will lift the shoelaces upward to prevent the shoelaces from rubbing against the shoe upper, and also enhance the stability of the main frame.

[0007] Furthermore, a strap inlet groove is provided on the outward-facing side wall of the first and third through grooves. The part of the strap inlet groove falls into the sub-frame, and the shoelace is inserted into the through groove through the strap inlet groove for easy strapping.

[0008] Preferably, each end face of the anti-slip bump protrudes beyond the end face of the rib, forming a stable channel for the shoelaces to wrap around and use, preventing the shoelaces from slipping after being threaded through.

[0009] Furthermore, the locking strap groove includes a strap hole, a locking strap section, and a curved section. The strap hole is configured to pass through the locking strap frame. The locking strap section is located near both sides of the locking strap frame. The two ends of the curved section connect the strap hole and the locking strap section, which are used to lock the strap end and facilitate fine-tuning of the shoelace tightness.

[0010] Preferably, the diameter of the threading hole is larger than the width of the locking strap section, and the groove width from the threading hole to the locking strap section is tapered to prevent the shoelaces from wobbling and to provide a feel for threading.

[0011] As an even better design, the two sides of the locking strap frame bend downwards to form the frame hem, and the upper surface of the frame hem is lower than the lower surface of the main frame, so that it fits the upper of the shoe and prevents it from wobbling.

[0012] As an even better design, the end of the locking strap extends outward while converging towards the main frame, shortening the overall length of the buckle and preventing the strap from loosening.

[0013] As an even better feature, the connection between the anti-slip bumps and the ribs is smooth, preventing damage to the surface of the shoelaces.

[0014] The second objective of this utility model is to provide a shoe that solves the problems of difficulty in adjustment and unattractive matching of existing shoes after using laceless shoelaces.

[0015] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0016] A shoe includes the aforementioned no-lace buckle, which securely engages the shoelaces after they are wrapped around the buckle and is easy to unlock by the buckle head. The tightness of the shoelaces can be easily adjusted, and the shoe is compact and aesthetically pleasing when paired with the shoe upper.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The main frame of the no-lace buckle is provided with a through part divided into three through slots by ribs. Several anti-slip protrusions are provided on the ribs. The anti-slip protrusions form a channel for the shoelace to pass through. After the shoelace is inserted into the channel, the anti-slip protrusions squeeze the strap. The shoelace can increase the friction of the shoelace by increasing the number of turns in the channel, thereby preventing slipping. A locking strap frame is provided on the side of the main frame. A locking strap groove is provided on the locking strap frame. The locking strap groove is used to lock the end of the shoelace and stretch the shoelace into a certain shape, which improves the aesthetics of the shoelace being inserted into the buckle and makes it convenient to adjust the tightness of the shoelace later.

[0019] (2) The main frame of the laceless shoe buckle has a secondary frame on the side. The secondary frame bends upward to support the shoelace that is inserted into the through part, preventing the shoelace from rubbing against the shoe surface and ensuring the outer surface of the shoelace. In addition, the two sides of the locking frame bend downward, making the locking frame fit the shoe surface more closely, preventing the buckle from shaking during use and improving the stability of the buckle itself.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] like Figures 1-4 As shown, this embodiment discloses a no-lace shoelace buckle, including a main frame 1. The main frame 1 has a through-hole and at least two ribs 115. The ribs 115 are parallel to each other, and both ends of each rib 115 are connected to the opposite side walls of the through-hole, dividing the through-hole into at least a first through-groove 111, a second through-groove 112, and a third through-groove 113. The first through-groove 111, the second through-groove 112, and the third through-groove 113 are parallel and spaced apart, allowing the shoelace 2 to pass through. Several anti-slip protrusions 114 are provided on the ribs 115, spaced apart along the length of the ribs 115, with adjacent anti-slip protrusions... A channel is formed between the protrusions 114 for the shoelace 2 to pass through. After passing through the channel, the shoelace 2 is wrapped around the rib 115. The anti-slip protrusions 114 increase the friction of the shoelace 2. By adjusting the number of turns of the shoelace 2 around the rib 115, the friction between the shoelace 2 and the buckle can be adjusted to meet the wearing needs of different types of shoes. The main frame 1 extends outward along one outer wall of the rib 115 to form a locking frame 12. The locking frame 12 is provided with a locking groove 121. The end 21 of the shoelace 2 is inserted into the locking groove 121 to fix the end 21, preventing the end 21 from swinging and pulling the shoelace 2 apart. It also makes the shoelace 2 as a whole fixed, improving the aesthetics of the appearance.

[0031] Preferably, there are two ribs 115, which makes the overall size small and beautiful.

[0032] Furthermore, secondary frames 11 are provided on both sides of the main frame 1. The secondary frames 11 are bent upward so that the end face of the secondary frames 11 is higher than the upper end face of the main frame 1. The secondary frames 11 contact the shoelaces 2 that are inserted into the through part, lifting part of the shoelaces 2 upward so that the shoelaces 2 do not contact the shoe surface, preventing the shoelaces 2 from being worn and loosened due to friction, improving the stability of the buckle fixing the shoelaces 2 and making the appearance more beautiful.

[0033] Furthermore, a strap inlet groove 116 is provided on the outward-facing side wall of the first through groove 111 and the third through groove 113. Part of the strap inlet groove 116 falls onto the sub-frame 11. The strap inlet groove 116 is used for the shoelace 2 to be threaded into the through part. The strap inlet groove 116 is set in an arc shape. By increasing the width of the through groove through the strap inlet groove 116, the shoelace 2 can be easily threaded into the through groove, making it more convenient to use.

[0034] Furthermore, each end face of the anti-slip protrusion 114 protrudes beyond the end face of the rib 115. The anti-slip protrusion 114 can restrict the movement direction of the shoelace 2 within the lace channel, prevent the shoelace 2 from contacting each other after being inserted, increase the contact area between the shoelace 2 and the rib 115 by increasing the friction, and also allow the shoelace 2 to separate, thus improving the aesthetics of the appearance.

[0035] Furthermore, the locking strap groove 121 includes a strap hole 1213, a locking strap portion 1211, and a bending portion 1212. The strap hole 1213 is configured to pass through the locking strap frame 12. The locking strap portion 1211 is located near both sides of the locking strap frame 12. The two ends of the bending portion 1212 connect the strap hole 1213 and the locking strap portion 1211. The shoelace 2 enters the locking strap groove 121 through the strap hole 1213. After the shoelace is threaded, the end of the strap 21 is pushed into the locking strap portion 1211 through the strap hole 1213 along the bending portion 1212. The width of the locking strap portion 1211 is smaller than the diameter of the shoelace 2, so that the end of the strap 21 is locked in the locking strap portion 1211. This prevents the end of the strap 21 from shaking and allows the shoelace 2 to be quickly opened when the tightness needs to be adjusted. Adjusting the tightness is more convenient, and the shoelace 2 is less likely to loosen after long-term use.

[0036] Preferably, the diameter of the threading hole 1213 is greater than the width of the locking strap portion 1211, and the groove width from the threading hole 1213 to the locking strap portion 1211 is tapered, which plays a guiding role when the shoelace 2 moves.

[0037] Preferably, a protrusion is provided on the side wall of the curved portion 1212 opposite to the opening of the locking strap portion 1211. The protrusion compresses the space for the shoelace 2 to move, provides a positioning feel for the locking strap, and can also prevent the shoelace 2 from coming out of the groove when shaking.

[0038] More preferably, the two sides of the locking strap frame 12 are bent downward to form the frame hem 13. The upper end of the frame hem 13 is lower than the lower end of the main frame 1. The frame hem 13 fits against the shoe upper to prevent the buckle from shaking during use.

[0039] More preferably, the end of the locking strap 1211 extends outward while converging towards the main frame 1, shortening the overall length of the buckle, reducing space occupation, and improving the aesthetics when paired with the shoe; more specifically, the locking strap 1211 is bent and deformed towards the main frame 1; or the locking strap 1211 is tilted and transitioned towards the main frame 1.

[0040] More preferably, the connection between the anti-slip protrusion 114 and the rib 115 is smooth, which prevents damage to the shoelace 2 when putting it on or adjusting it, and reduces the resistance when adjusting the tightness of the shoelace 2, making the operation more convenient.

[0041] The process of using this no-lace shoelace buckle is as follows:

[0042] The end 21 of the shoelace 2 is inserted from below the threading hole 1213 into the first through groove 111, and then enters the second through groove 112 along the strap channel on the rib 115. The number of turns around the rib 115 is selected according to the required firmness, and then it is inserted from below into the threading hole 1213. The length of the shoelace 2 inserted into the through part is adjusted, and then the shoelace 2 in the threading hole 1213 is pushed into the locking strap part 1211 through the bending part 1212 and fixed. When adjusting the tightness of the shoelace 2, the end 21 is pulled out from the locking strap part 1211 to the threading hole 1213 to adjust the length and tightness of the locking strap. After adjustment, the end 21 is pulled back into the locking strap groove 121 for fixing.

[0043] Example 2

[0044] like Figure 5 and Figure 6 As shown, this embodiment also discloses a shoe, including a lace-free buckle, a shoe body 3 and shoelaces 2. The shoelace buckle is attached to the upper surface of the shoe body 3 after the shoelaces 2 are inserted. The friction between the shoelaces 2 and the shoelace buckle can be adjusted by releasing the end 21 of the shoelaces 2, thereby adjusting the tightness.

[0045] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
