Description

Shoelace fixing device Technical Field

[0001] The present invention relates to the technical field of shoe accessories, in particular to a shoelace fixing device. Background Art

[0002] Currently, traditional shoelaces are the primary method of putting on and taking off footwear, with a smaller number of alternatives using zippers, Velcro, or elastic bands. However, traditional shoelaces are slow to put on and take off and easily become loose; zippers and Velcro can affect the overall design and structure of the shoe; and elastic bands not only affect the overall design and structure of the shoe but also have the problem of not fitting snugly.

[0003] In this regard, the prior art has proposed the following solutions, however, these solutions also have their own shortcomings:

[0004] (1) Knob type: A special string (nylon or carbon fiber) is used. The knob tightens the string to fit the foot, and pressing the knob loosens the string. However, the tightness must be adjusted every time the shoes are put on or taken off. The structure is complex, the string must be used, and the cost is high.

[0005] (2) Double-hole bayonet type: The shoelaces or string are passed through the double-hole buckle, and the shoelaces or string are clamped with spring teeth. Press forward to loosen and push back to tighten. However, the shoelaces or string cannot be completely locked, which affects the appearance.

[0006] (3) Buckle and elastic band combination: insert the elastic band into the eyelet of the shoe, trim the shoelace head, and install the buckle to connect. However, the shoes using this solution do not fit the foot well and are only suitable for walking and slow walking, not for high-intensity sports such as playing ball and running.

[0007] (4) Slide-in heel: The heel needs to be specially shaped to fit the elastic band at the neckline, so that it can be directly slid in or out. However, the shoes using this solution do not fit the foot well and have limitations on the appearance and structure.

[0008] Therefore, it is necessary to provide a shoelace fixing device which can firmly fix the shoelaces, is easy to put on and take off, and fits the foot.

[0009] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore it may contain information that does not constitute the prior art known to those skilled in the art.

[0031] The present invention is described in detail below through specific embodiments so that those skilled in the art can easily implement the present invention according to the contents disclosed in this specification. The embodiments described below are only some embodiments of the present invention, not all. Based on the embodiments described in this specification, all other embodiments obtained by those skilled in the art without paying creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this specification and the features in the embodiments can be combined with each other unless there is a conflict.

[0032] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] Figure 1 schematically shows a perspective view of a first locking buckle 1 of a shoelace fixing device according to an embodiment of the present invention. As shown in Figure 1 , the shoelace fixing device comprises: a first locking buckle 1 , and the first locking buckle 1 comprises: an upper locking piece 11 and a lower locking piece 12 .

[0034] Further reference is made to Figure 4, which schematically illustrates a perspective view of the upper locking plate 11 in Figure 1. As shown in Figure 4, the upper locking plate 11 has a generally flat sheet-like structure. However, the sheet-like structure can optionally be curved to accommodate the shapes and designs of different types and styles of shoes. As shown in Figure 4, two shoelace holes 111 are symmetrically defined on one side of the upper locking plate 11. A wrench 113 is positioned between the two shoelace holes 111, and a tongue 112 is positioned in the middle of the other side of the upper locking plate 11. In other embodiments of the present invention, multiple shoelace holes 111 may be provided depending on the specific situation and actual needs. The arrangement of the shoelace holes 111, tongue 112, wrench 113, and their relative positions may not be limited to the arrangement shown in Figure 4. This may also vary according to actual needs, and the present invention is not specifically limited to this.

[0035] Referring further to FIG. 5 , a schematic perspective view of the lower locking plate 12 in FIG. 1 is shown. As shown in FIG. 5 , the lower locking plate 12 also has a generally straight sheet-like structure. However, the sheet-like structure can optionally be curved to accommodate the shape and design of different shoe types and styles, or to accommodate the shape of the upper locking plate 12 when the upper locking plate 12 has a curved sheet-like structure. FIG. 5 shows that two shoelace holes 121 are symmetrically defined on one side of the lower locking plate 12. A receptacle 122 is located between the two shoelace holes 121. The receptacle 122 mechanically engages with the tongue 112 of the upper locking plate 11, allowing the tongue 112 to engage therewith. In other embodiments of the present invention, multiple shoelace holes 121 can be provided depending on specific circumstances and actual needs. Furthermore, the arrangement of the shoelace holes 121, the receptacle 122, and their relative positions are not limited to the arrangement shown in FIG. Such arrangements can also vary based on actual needs, and the present invention is not specifically limited thereto.

[0036] To further illustrate the internal structure of the first locking buckle 1 shown in FIG1 , a detailed description will be given below with reference to a cross-sectional view taken along line AA of the top view of the first locking buckle 1 shown in FIG2 . FIG3 shows a cross-sectional view of the upper locking piece 11 and the lower locking piece 12 of the first locking buckle 1 shown in FIG1 when they are engaged. A first recess 114 is defined in the middle of the lower surface (not shown) of the upper locking piece 11, and a first magnet 115 is embedded in the first recess 114 and protrudes from the lower surface of the upper locking piece 11. Similarly, a second recess 123 is defined in the middle of the upper surface 125 (also see FIG5 ) of the lower locking piece 12, and a second magnet 124 is embedded in the second recess 123 and recessed into the upper surface 125 of the lower locking piece 12, so as to magnetically attract the upper locking piece 11 and the lower locking piece 12 together when magnetically coupled with the first magnet 115.

[0037] Further reference to FIG. 5 shows that the second magnetic block 124 is disc-shaped. While the shape of the first magnetic block 115 is not clearly shown in the figure, to achieve better magnetic coupling, the first magnetic block 115 is generally configured to match the shape of the second magnetic block 124, i.e., a disc shape. However, in other embodiments of the present invention, the two magnetic blocks can also be configured in other shapes to meet different design requirements and practical needs. Furthermore, which magnetic block protrudes or recesses can be changed based on actual conditions, or both magnetic blocks can be neither protruding nor recessed from the lower surface of the upper locking plate 11 nor the upper surface of the lower locking plate 12. The present invention does not limit this. Similarly, the positions of the two recesses in which the two magnetic blocks are embedded can also be adaptively changed based on design requirements and practical needs.

[0038] In a specific embodiment of the present invention, the first locking buckle 1 can be arranged in the middle position of the top of the two rows of shoelace holes on the shoe or on the upper end of the tongue. When using the first locking buckle 1, the shoelaces on one side can be passed through the shoelace holes 111 of the upper locking plate 11, and the shoelaces on the other side can be passed through the shoelace holes 121 of the lower locking plate 12. After the shoelaces are passed through and the upper and lower locking plates are in a buckled state, after adjusting the shoelace length to the appropriate tightness of the shoe, the position of the shoelaces can be fixed by tying the shoelaces, etc., thereby fixing the first locking buckle 1 to the shoe.

[0039] When putting on shoes, it is necessary to buckle the upper locking piece 11 and the lower locking piece 12 that were originally separated together, that is, to bring the upper locking piece 11 and the lower locking piece 12 closer together, first make the tongue 112 of the upper locking piece 11 fit into the insertion hole 122 of the lower locking piece 12, then align the first magnetic block 115 and the second magnetic block 124, and make the two magnetic blocks magnetically attracted together, thus completing the buckling of the upper locking piece 11 and the lower locking piece 12, thereby tightening the shoelaces.

[0040] When taking off the shoes, the wrench 113 of the upper locking piece 11 can be lifted upward by hand to separate the two magnetic blocks, and then the tongue 112 of the upper locking piece 11 can be pulled out from the insertion hole 122 of the lower locking piece, thus completing the separation of the upper locking piece 11 and the lower locking piece 12, thereby loosening the shoelaces.

[0041] In a preferred embodiment of the present invention, the shoelace fixing device further includes a second buckle 2. Referring to Figure 6 , a perspective view of the second buckle 2 according to an embodiment of the present invention is schematically shown. As shown in Figure 6 , the second buckle 2 has a third shoelace hole 21 and a fourth shoelace hole 22 formed in parallel.

[0042] Further reference to the side perspective view of the second buckle 2 of FIG. 6 shown in FIG. 7 , shows that the second buckle 2 has a generally flat sheet-like structure. However, the sheet-like structure can optionally be curved to accommodate the shapes and designs of different types and styles of shoes, or to better adapt to the shape of the first buckle 1 when it has a curved sheet-like structure. As shown in FIG. 7 , the third shoelace eyelet 21 is perpendicular to the upper surface 23 and lower surface 24 of the second buckle 2, while the fourth shoelace eyelet 22 is an inclined through-hole relative to the upper surface 23 and lower surface 24 of the second buckle 2. In other words, the fourth shoelace eyelet 22 forms an angle θ with the third shoelace eyelet 21. This design ensures that the shoelaces are locked in place, preventing them from loosening or moving. The angle θ can range from 20° to 70° to accommodate the shapes and designs of different types of shoes.

[0043] In a specific embodiment of the present invention, the second buckle 2 can be attached to the outside of the top of the two rows of shoelace holes on the shoe. The shoelace passed through the first shoelace hole 111 of the first buckle 1 can be simultaneously passed through the third shoelace hole 21 and the fourth shoelace hole 22 of the second buckle 2. Similarly, the shoelace passed through the second shoelace hole 121 of the first buckle 1 can be simultaneously passed through the third shoelace hole 21 and the fourth shoelace hole 22 of the second buckle 2. In other words, one second buckle 2 can be provided on each side of the first buckle 1. When wearing the shoe for the first time, the shoelace can be passed through the fastened first buckle 1 and the second buckle 2 can be used to adjust the tension and secure or lock the shoelace in place. Of course, to achieve different shoelace tightening effects or meet the requirements of different types of shoes, such as high-top shoes, two or more first buckles 1 and / or multiple second buckles 2 can be provided.

[0044] In a preferred embodiment of the present invention, the first lock buckle 1 and / or the second lock buckle 2 can be made of ABS or carbon fiber materials according to different strength requirements. Of course, other suitable materials known to those skilled in the art can also be used, and the present invention does not specifically limit this.

[0045] The shoelace fixing device described in the present invention has no special requirements for the material of the shoelaces and can be used with all types of shoes that use shoelaces. The original shoelaces can be retained without affecting the structure and appearance of the shoes. In contrast, existing shoe buckles require the shoelaces to be made of nylon or elastic bands. At the same time, the shoelace fixing device described in the present invention combines magnetic attraction and mechanical snap-fit ​​structures, making the entire shoelace fixing device easy to open and close and firmly combined, and not easy to disengage, so that the shoes fit the feet. After the first adjustment of the shoelaces, there is no need to adjust the tension again, making the shoes quick to put on and take off and easy to operate. Furthermore, the shoelace fixing device described in the present invention has at least four shoelace holes, which increases the opening, making it easier for the foot to enter and exit, making it easier to put on and take off the shoes. Moreover, the shoelace fixing device described in the present invention has a simple structure, low cost, and a market price advantage.

[0046] It should be understood that the structures shown in the accompanying drawings are merely illustrative. Depending on actual needs, the shoelace fixing device may include more or fewer modules or components than shown in the drawings, or have a configuration different from that shown in the drawings. Furthermore, the arrangement and number of the components of the shoelace fixing device are for illustrative purposes only and are not intended to limit the present invention.
