Description

Technical Field

[0001] The utility model relates to a shoelace and a shoe comprising the shoelace. Background Art

[0002] In the footwear industry, shoelaces are an important part for fixing the upper and adjusting the tightness of shoes, and are widely used in various shoe styles. However, a common problem with existing shoelaces is that they need to be tied manually, which brings a lot of inconvenience to users in daily life.

[0003] First, traditional shoelace designs require users to spend time and effort to pass the shoelaces through the eyelets and fasten them. This process may require multiple adjustments and operations, which is especially difficult for elderly or mobility-impaired users, who may not be able to bend down easily to tie their shoelaces or need help from others. Second, traditional shoelace designs may not be safe enough in some cases. For example, when users are walking, running, or otherwise active, shoelaces may loosen or untie, increasing the risk of users tripping or getting injured. This situation not only affects the user's comfort, but may also affect their satisfaction with the product and their confidence in safety. Third, in emergency situations, such as when you need to quickly change shoes or adjust the tightness of your shoes, the manual fastening method obviously cannot meet the needs of speed and convenience.

[0004] In summary, although the traditional shoelace design meets the basic functional requirements of footwear products to a certain extent, there are still problems such as inconvenience for users and lack of safety. Utility Model Content

[0026] Hereinafter, embodiments of a shoelace and a shoe including the shoelace of the present invention will be described with reference to the accompanying drawings.

[0027] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the contents disclosed in the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.

[0028] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0029] Figures 1 to 4The shoelace and the shoe with the shoelace of one embodiment of the utility model are shown, which include: a first segment 11, a second segment 12, a third segment 13, a fourth segment 14 and a fifth segment 15 connected in sequence. Those skilled in the art should know that the above segments can be a shoelace formed by connecting and combining multiple separate segments during production, or a shoelace formed in one piece (such as a silicone or latex material formed in one piece), and the description form of the segments is used only for the convenience of structural description. The second segment 12 and the fourth segment 14 can be switched between the stretched state and the contracted state. The second segment 12 and / or the fourth segment 14 have a first diameter in the stretched state, and the second segment 12 and / or the fourth segment 14 have a second diameter in the contracted state; the first diameter is less than or equal to the diameter of the shoelace hole, and the second diameter is greater than the diameter of the shoelace hole.

[0030] like Figure 1 As shown, the fourth segment of the shoelace is in a stretched state, at which time it has a first diameter, and the first diameter is less than or equal to the diameter of the shoelace hole. In the stretched state, the shoelace can be conveniently passed through the shoelace hole set on the upper, so that the user can adjust the length (tightness) of the shoelace. After adjusting to the desired suitable length, the fourth segment of the shoelace is operated to be in a contracted state (such as Figure 4 As shown in FIG. 1 ), the fourth segment has a second diameter, and the second diameter is greater than the diameter of the shoelace hole. In the contracted state, the shoelace can be positioned by the cooperation between the fourth segment and the shoelace hole, so that the shoelace is kept at the length set by the user. The fourth segment has a variety of applicable forms to achieve positioning with the shoelace hole of the upper. Figure 5 In the embodiment of the present invention, the shoe upper is clamped in the middle of the fourth segment and the fourth segment is contracted, so that the shoe upper is clamped in the middle of the fourth segment. In another use mode, only the following part of the fourth segment is contracted: the part between the shoe upper and the fifth segment, so that the diameter of the fourth segment on one side of the shoe upper is larger than the diameter of the shoelace hole, and can cooperate with the shoe upper to achieve the clamping position. When the shoelace of the utility model is used, the second segment and the fourth segment are operated to switch between the stretched and contracted states to achieve the positioning of the shoelace in the shoelace hole, without the need for cumbersome buckling operations, and has the advantages of being more convenient and time-saving to use, so that it is more suitable for children, the elderly or users with limited mobility.

[0031] Combination Figure 2 As shown, in a specific embodiment of the shoelace, the second segment 12 and the fourth segment 14 are composed of mutually connected V-shaped folded portions 141, and the V-shaped folded portion specifically refers to a V-shaped structure in the cross section along the middle. Between the folded portions 141 is a connecting portion 142, which can be a separately provided component, such as a ring-shaped component with a length of less than 2 mm, and the connecting portion can also refer to the connecting portion of two adjacent folded portions.

[0032] Figure 1-6The shoelace embodiment shown is only a preferred structure. In another preferred shoelace structure, the first segment 11, the third segment 13, and the fifth segment 15 have the same structure as the second segment 12 and the fourth segment 14, and are all composed of interconnected V-shaped folded portions 141. That is to say, in this embodiment, the shoelace is entirely composed of interconnected V-shaped folded portions 141. When in use, the shoelace is positioned by stretching and contracting different shoelace parts and coordinating the positions of the shoelaces in the shoelace holes of the shoe upper, thereby adjusting the tightness of the shoe upper.

[0033] The shoelace of the utility model can be made of one material or two or more materials. In a specific embodiment, the first segment 11, the third segment 13, and the fifth segment 15 of the shoelace are made of silicone or latex materials, and the second segment 12 and the fourth segment 14 are made of plastic materials. In the above specific embodiment, the second segment and the fourth segment are made of plastic materials with better hardness, which can meet the strength requirements when the shoelace is locked with the upper, and avoid the second segment and the fourth segment being stretched and then shifted in the shoelace hole when the shoelace is accidentally stretched, so as to loosen the shoelace.

[0034] In another specific embodiment, the first segment 11, the second segment 12, the third segment 13, the fourth segment 14 and the fifth segment 15 are all made of one of silicone material, latex material or plastic material, that is, the shoelace is made of only one material, which has the advantage of lower processing cost. At this time, it is necessary to select a material with suitable hardness and elasticity to make the shoelace. When the shoelace is made of silicone or latex material, due to the hardness of the material, there may be a problem that the second segment and the fourth segment are stretched and then shifted in the shoelace hole when the shoelace is accidentally stretched, causing the shoelace to loosen. The inventor further improved it. In a further preferred embodiment, the second segment 12 and the fourth segment 14 are hollow structures, an annular groove 143 is provided on the inner wall of the V-shaped folding portion 141, and a first magnetic component 3 is provided in the annular groove 143. The first magnetic component 3 is a permanent magnet, and the magnetic poles of adjacent permanent magnets are in the same direction (for example, the permanent magnets are arranged in a magnetic pole arrangement mode of NS NS NS). According to the above embodiment, the magnetic force between adjacent first magnetic components can be used to provide a maintaining force for the second segment and the fourth segment in a contracted state. When the shoelaces are accidentally stretched, the magnetic force needs to be overcome, thereby avoiding accidental loosening of the shoelaces to a greater extent.

[0035] In another specific embodiment, the first magnetic component 3 is made of ferromagnetic material (for example, the first magnetic component is a round iron sheet), and further includes a second magnetic component 4, which is fixed to the end of the first segment 11 close to the second segment 12, and the end of the fifth segment 15 close to the fourth segment 14; the second magnetic component 4 is a permanent magnet. According to this structure, when the first magnetic component is close to the second magnetic component, the second magnetic component provides a magnetic attraction force to the first magnetic component, and the magnetic attraction force provides a maintenance force for the second segment and the fourth segment in the contracted state, and the magnetic force needs to be overcome when the shoelaces are accidentally stretched, thereby preventing the shoelaces from accidentally loosening to a greater extent.

[0036] The utility model also provides a shoe with shoelaces, comprising a sole and an upper 2 connected to the upper part of the sole, wherein the upper 2 is provided with shoelace holes 21, and shoelaces 1 are arranged in the shoelace holes 21, and the shoelaces 1 are the shoelaces of the above embodiment.

[0037] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the utility model to achieve the purpose of the utility model.
