Description

shoelaces

The invention relates to a shoelace.

Conventional shoelaces are mostly woven from multiple strands, and the appearance can only be changed by changing the weaving method or the color of the strands, and the variability is limited. If you want to provide shoelaces with different stretch rates, you need to change the manufacturing process or use strands of different specifications, which is not conducive to manufacturing. In addition, the outer surface of the conventional shoelaces generally extends smoothly, and the friction force is insufficient when binding, so it is easy to loosen, which has a shortcoming that needs to be improved urgently.

Therefore, it is necessary to provide a novel and progressive shoelace to solve the above problems.

The main purpose of the present invention is to provide a shoelace that can adjust the expansion and contraction rate, is not easy to loosen when tied, and has good appearance.

In order to achieve the above object, the present invention provides a shoelace, including: a core material defining an axial direction; and a covering layer, at least partially slidably sleeved on the core material along the axial direction, including a plurality of third layers. A strand and a plurality of meshes woven from the plurality of first strands, the core material is partially exposed outward from the plurality of meshes.

The following examples are only used to illustrate the possible implementation modes of the present invention, but are not intended to limit the scope of protection of the present invention.

Please refer to Figures 1 to 4, which show a preferred embodiment of the present invention. The shoelace 1 of the present invention includes a core material 10 and a covering layer 20.

The core material 10 defines an axial direction. The coating layer 20 is at least partially sleeved on the core material 10 so as to be relatively slidable along the axial direction. The coating layer 20 includes a plurality of first strands 21 and a plurality of first strands 21 braided. Mesh 22, the core material 10 is partially exposed outward from the plurality of meshes 22, whereby the shoelace 1 has a relatively concave and convex outer surface to provide a special visual effect, and can also provide greater friction when binding. It is not easy to loosen and has good use effect, and the plurality of mesh holes 22 allows the covering layer 20 to have a stretch margin so that the stretch rate of the shoelace 1 can be adjusted.

In this embodiment, the plurality of meshes 22 are continuously arranged along the axial direction, and two adjacent meshes 22 in the circumferential direction of the core material 10 are at least partially offset to prevent the coating layer 20 from overlapping each other during compression. The thickness is increased to provide sufficient flexibility. During bundling, the overlapping and abutting portions of the coating layer 20 can be partially embedded in the plurality of meshes 22 through the plurality of first strands 21 , and the coating layer 20 can be relative to the core material when stressed. 10. It can move wrongly without being easily pulled by force. It has good stability and is not easy to loosen. However, the plurality of meshes can also be arranged at intervals.

The cladding layer 20 can expand and contract under force along the axial direction relative to the core material 10 , and the ratio of the length change of the cladding layer 20 before and after expansion to the length of the cladding layer 20 before expansion ranges from 0.2 to 0.8; for example Say, if the length of the coating layer 20 when not stretched is 2 cm, the coating layer 20 can be stretched to 2.5 cm or compressed to 1 cm. During manufacturing, one end of the covering layer 20 in the axial direction can be first fixed to the core material 10 by shoelace head, knotting or splicing, etc., and then the other end of the covering layer 20 is opposite to the core material 10 It is stretched along the axial direction (as shown in Figure 4) or compressed to a desired length and then fixed with the core material 10. For example, assuming that the core material 10 is a stretchable rope, if the covering layer 20 is stretched and tightened and then fixed to the core material 10, the covering layer 20 cannot be further stretched. , the shoelace 1 has a small expansion rate and a high tensile strength; if the covering layer 20 is compressed and then fixed to the core material 10, the covering layer 20 can expand and contract with the core material 10, and the shoelace The expansion ratio of 1 depends on the core material 10 and allows a larger expansion ratio. The expansion ratio can be adjusted according to needs without changing the weave or material.

In this embodiment, the core material 10 is knitted by a plurality of second strands 11. The plurality of second strands 11 form a plurality of interlaced portions 12 on the outer surface of the core material 10. The plurality of interlaced portions 12 are at least partially Corresponding to the plurality of meshes 22, it has special visual effects. The core material 10 is a flat rope. The width of the flat rope is greater than the inner diameter of the covering layer 20 . The flat rope is folded transversely to the axial direction to provide appropriate friction and a large deformation margin. . However, the core material can also be a round rope, which can be selected according to needs.

In detail, the covering layer 20 is knitted (preferably warp knitted) from the plurality of first strands 21 and forms a plurality of coils 23 that are inserted into each other. The height of each coil 23 is less than one of the mesh holes. 22 in the axial direction; at least four coils 23 surround one mesh 22, and the expansion rate is large. The plurality of first strands 21 are reciprocally bent and extended in the circumferential direction to form a plurality of first extension sections 211 and a plurality of second extension sections 212 that are staggered with each other in the axial direction. The extension direction of each first extension section 211 E1 is different from an extension direction E2 of each second extension section 212 and is oblique to the axial direction, so as to surround the plurality of mesh holes 22 with larger opening sizes. Each first extension section 211 includes at least two first coils 231 that are inserted into each other. Each second extension section 212 includes at least two second coils 232 that are inserted into each other. One of the first coils is adjacent in the axial direction. 231 and a second coil 232 are connected through each other to connect a first extension section 211 and a second extension section 212; in the circumferential direction, the plurality of first extension sections 211 and the plurality of second extension sections 212 are staggered. , good structural strength and good aesthetics.

In this embodiment, the number of the plurality of first strands 21 is 6; the colors of the plurality of first strands 21 and the plurality of second strands 11 are different and have good appearance; each of the meshes 22 is made of different shapes. Corresponding two first extension sections 211 and corresponding two second extension sections 212 are formed; the at least two first coils 231 of each first extension section 211 are circumferentially opposite to one of the second extension sections. The at least two second coils 232 of the segment 212 are at least partially inserted into each other to form a connecting portion 213. Each of the connecting portions 213 is located between two adjacent meshes 22. It has good structural strength and can form a special weaving pattern. In other embodiments, the plurality of first strands may also include at least two different colors to provide various appearance changes.
