An elastic buckle and shoes with the elastic buckle.

Abstract

This utility model relates to the field of footwear and apparel accessories technology, providing an elastic buckle and a shoe with the elastic buckle. The elastic buckle includes a buckle body with two centrally symmetrical sliding grooves running through it. Each sliding groove has a first through hole and a second through hole. The distance between the second through hole and the center of symmetry is less than the distance between the first through hole and the center of symmetry. A snap-fit ​​structure is provided at the second through hole to hold the shoelace. The sliding grooves allow the shoelace to slide between the first and second through holes. Because the two sliding grooves are centrally symmetrical about the midpoint of the entire elastic buckle, and the shoelace can slide within the sliding grooves, when the user rotates the elastic buckle, the shoelace slides from the second through hole to the first through hole. The distance between the two second through holes is less than the distance between the two first through holes, thus tightening the shoelace.

Description

Technical Field

[0001] This utility model belongs to the field of footwear and apparel accessories technology, and in particular relates to an elastic buckle and shoes with the elastic buckle. Background Technology

[0002] Shoelaces are straps used to tighten the inner and outer uppers of shoes and serve a decorative purpose. Their primary function is to adjust the tightness of the shoe and ensure ankle safety. There are two common methods for threading shoelaces through the eyelets: a crisscross topology and a parallel array structure. The crisscross method (woven mesh) creates a mesh tension by diagonally interlacing the shoelaces between the left and right eyelets, providing a dynamic fit. The parallel method (track laying) allows the shoelaces to pass vertically through one eyelet, forming a parallel stress band for more even pressure distribution. Both methods utilize eyelet constraints to achieve quick tightness adjustment and secure locking.

[0003] However, in cross-topology shoelaces, rigid friction nodes are formed at the intersections, generating self-locking static friction at these nodes when the system is tightened. In parallel array shoelaces, the tension is independently anchored to adjacent eyelets, forming segmented island constraints that prevent local in-situ fine-tuning. Therefore, regardless of whether it's a cross-topology or parallel array structure, it's difficult to adjust the tightness of the shoelaces between two rows of eyelets after they are tightened. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an elastic buckle, which aims to solve the problem of difficulty in adjusting the tightness of the shoelaces between two rows of eyelets.

[0005] This utility model embodiment is implemented as follows: an elastic buckle includes a buckle body, through which two centrally symmetrical sliding grooves are provided. A first through hole and a second through hole are provided on each sliding groove. The distance between the second through hole and the center of symmetry is less than the distance between the first through hole and the center of symmetry. A snap-fit ​​structure is provided at the second through hole to hold the shoelace. The sliding grooves are used for the shoelace to pass through, allowing the shoelace to slide between the first through hole and the second through hole.

[0006] Furthermore, the center of symmetry is located between the first perforation and the second perforation.

[0007] Furthermore, the groove is curved.

[0008] Furthermore, the snap-fit ​​structure is a snap-fit ​​block, which is disposed on the slide groove and is used to snap the shoelace into the second perforation.

[0009] Furthermore, the groove is hook-shaped, and the second perforation is located at the hook position.

[0010] Furthermore, the first perforation, the center of symmetry, and the second perforation are on the same straight line.

[0011] Furthermore, several anti-slip strips are provided on the outer side of the buckle body.

[0012] Another object of this utility model embodiment is a shoe with an elastic buckle, the shoe comprising:

[0013] The shoe body has two rows of eyelets on its upper;

[0014] The shoelace has one end passed through one row of eyelets and the other end passed through another row of eyelets.

[0015] Several elastic buckles are provided between the two rows of eyelets, and the two ends of the shoelaces pass through the two grooves respectively, so that the elastic buckles connect the shoelaces on the two rows of eyelets.

[0016] This embodiment of the invention provides an elastic buckle with a horizontally arranged design. Two shoelaces (or the two ends of a single shoelace) pass through two longitudinally arranged grooves. In the relaxed state, both shoelaces are located on the first perforation; in the taut state, both shoelaces are located on the second perforation. Because the two grooves are symmetrical about the midpoint of the entire elastic buckle, and the shoelaces can slide within the grooves, when the user rotates the elastic buckle, the shoelaces slide from the second perforation to the first perforation. The distance between the two second perforations is less than the distance between the two first perforations, thus tightening the shoelaces. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0024] In the first embodiment, such as Figure 1-4 As shown, an elastic buckle is proposed, comprising a buckle body 1, wherein the buckle body 1 is provided with two centrally symmetrical sliding grooves 2, and the sliding grooves 2 are provided with a first through hole 3 and a second through hole 4, wherein the distance between the second through hole 4 and the center of symmetry 5 is less than the distance between the first through hole 3 and the center of symmetry 5, and a snap-fit ​​structure is provided at the second through hole 4 for securing the shoelace; the sliding grooves 2 are used for the shoelace to pass through, so that the shoelace can slide between the first through hole 3 and the second through hole 4.

[0025] In this embodiment, the elastic buckle is arranged horizontally, and the two shoelaces (or the two ends of a single shoelace) pass through two longitudinal grooves 2 respectively. In the loose state, both shoelaces are located on the first perforation 3, and in the taut state, both shoelaces are located on the second perforation 4. Since the two grooves 2 are symmetrical about the midpoint of the entire elastic buckle, and the shoelaces can slide within the grooves 2, when the user rotates the elastic buckle, the shoelaces slide from the second perforation 4 to the first perforation 3. The distance between the two second perforations 4 is less than the distance between the two first perforations 3, thus tightening the shoelaces.

[0026] In this embodiment, the elastic buckle is an independent buckle structure that can be used on shoes, as well as on the drawstrings or ties of clothing. Figure 1 As shown, three feasible elastic buckles are provided. The groove 2 in this embodiment is not limited in shape; it can be a zigzag groove, but a curved groove is preferred for smoother sliding and easier operation. Similarly, the shape of the buckle body is not specifically limited. The groove 2 is not limited to the first perforation 3 and the second perforation 4; a third or fourth perforation can also be provided. The principle is the same: adjusting the distance between the two shoelaces passing through the groove 2 changes the tightness.

[0027] In this embodiment, as Figure 2-4 As shown, the center of symmetry 5 is located between the first through hole 3 and the second through hole 4. Several anti-slip strips (such as...) are provided on the outer side of the buckle body 1. Figure 1 The first picture and Figure 2 (As shown). The first perforation 3, the center of symmetry 5, and the second perforation 4 are on the same straight line. This design allows users to loosen or tighten the shoelaces by rotating them. To tighten, rotate the buckle 180° clockwise or counterclockwise; to loosen, rotate it 180° in the opposite direction.

[0028] In this embodiment, the snap-fit ​​structure serves to secure the shoelaces to the second perforation 4, ensuring they do not come undone. This embodiment provides two snap-fit ​​structures that conform to this snap-fit ​​method. For example... Figure 4 As shown, the first type is a locking structure consisting of a locking block 6, which is disposed on the sliding groove 2 and used to lock the shoelace into the second through hole 4. The locking block 6 needs to be positioned inside the sliding groove 2 to reduce the spacing between the grooves. Figure 2 and 3 As shown, the second type is where the groove 2 is hook-shaped, and the second through hole 4 is located at the hook position.

[0029] In a second embodiment, a shoe with an elastic buckle is proposed, the shoe comprising:

[0030] The shoe body has two rows of eyelets on its upper;

[0031] The shoelace has one end passed through one row of eyelets and the other end passed through another row of eyelets.

[0032] The elastic buckle described in the first embodiment is disposed between the two rows of eyelets, and the two ends of the shoelace pass through the two grooves 2 respectively, so that the elastic buckle connects the shoelaces on the two rows of eyelets.

[0033] In this embodiment, the method of tightening the shoelaces differs from the cross topology structure and parallel array structure (horizontally parallel) mentioned in the background art. Instead, a shoelace is passed longitudinally through two rows of eyelets in sequence, and then the elastic buckle is used as a connector to connect the two rows of eyelets laterally. Thus, the tightness of the shoelaces can be adjusted by several elastic buckles.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
