Description

shoelace

The present invention relates to a shoelace.

Conventionally, most of the problems often encountered with shoelaces are not easy to slip off and fall off. Therefore, in order to avoid the problem of shoelace falling off, a variety of structurally specific shoelaces are available, which can improve the problem of shoelace slippage.

Among them, the most common is to make the shoelace have a thick and thin staggered change, such as patent TW I611774, TW M529401, TW M447117, TW M421015, TW M394015, TW M349209, TW M339939, TW M337982, TW M253245, TW M240854, TW 479474, etc. However, such a structure is quite difficult to manufacture. What is important is that the appearance is unsightly. When it is worn around the shoelace hole of the shoe body, it is more hindered, and the knot must be just hit in the concave or smaller diameter. At that point, otherwise the effect of preventing slippage is lost.

In this regard, there is another type of anti-slip lace-off shoe as described in the patents TW I539907, TW M521914, etc., in which an inner core is threaded with an inner core, and the inner core has a thick and thin interlaced structure, and the outer core is compared with the outer core. The deformation of the detail reaches the function of tying the knot to prevent slippage. However, although such a structure improves the appearance of the problem, the structure of the inner core is still difficult to manufacture like the shoelace described in the above paragraph, and must be worn to In the outer tube, the process is more complicated and needs to be improved.

The main object of the present invention is to provide a shoelace which has the advantages of being beautiful, easy to wear and not easy to fall off.

In order to achieve the above object, the present invention provides a shoelace comprising a tubular body woven from each other by at least four first wire bodies, at least four second wire bodies, at least four third wire bodies and at least four fourth wire bodies. The body defines an axial direction, and each of the first wire body and each of the second wire bodies are made of thermoplastic polyurethanes (TPU), and each of the third wire bodies is the same as each of the fourth wire bodies. The first wire body and each of the second wire bodies respectively extend left-handed and right-handedly, and each of the third wire body and each of the fourth wire body respectively has a left-handed and a right-handed extension. The first line body is substantially parallel to each of the third line bodies, and each of the second line bodies is substantially parallel to each of the fourth line bodies, and the first line bodies are arranged in alignment with the third line bodies, and the second lines are arranged The wire body and the fourth wire body are arranged in an interlaced manner, and the first wire body and the third wire body are woven with each other, and the number of the first wire body and each of the second wire body is smaller than each of the third wire bodies The number of Dans with each of the fourth line bodies.

The following is a description of the possible embodiments of the present invention, and is not intended to limit the scope of the invention as claimed.

Referring to FIG. 1 to FIG. 3, the present invention provides a shoelace comprising at least four first wire bodies 11, at least four second wire bodies 12, at least four third wire bodies 13, and at least four fourth wire bodies 14 to each other. Weaving one of the tubular bodies 10, the tubular body 10 defines an axial direction, and each of the first wire bodies 11 and each of the second wire bodies 12 are made of Thermoplastic polyurethanes (TPU), each of which is Each of the third wire bodies 13 and the fourth wire body 14 are made of polyester fiber, and each of the first wire body 11 and each of the second wire bodies 12 is left-handed and right-handed, and each of the third wire bodies 13 is 13 And each of the fourth linear bodies 14 is left-handed and right-handed, and each of the first linear bodies 11 and the third linear bodies 13 are substantially parallel, and each of the second linear bodies 12 and each of the fourth linear bodies 14 In parallel, the first line bodies 11 and the third line bodies 13 are arranged in an interlaced manner, and the second line bodies 12 and the fourth line bodies 14 are arranged in an interdigitated manner with the first line bodies 11 and the The third wire bodies 13 are woven with each other, and the number of the first wire body 11 and each of the second wire bodies 12 is smaller than the number of the third wire body 13 and each of the fourth wire bodies 14; The material 20 is inserted into the tubular body 10 to extend along the axial direction, as shown in FIG.

In this embodiment, each of the first line body 11 and the second line body 12 have the same number of dens, and each of the third line bodies 13 has the same number of dens as each of the fourth line bodies 14; each of the first lines The outer diameter of the body 11 and each of the second wire bodies 12 is less than one fifth of the outer diameter of each of the third wire body 13 and each of the fourth wire bodies 14; preferably, each of the first wire bodies 11 and The number of deniers of each of the second linear bodies 12 is 300 dan, and the number of deniers of each of the third linear bodies 13 and each of the fourth linear bodies 14 is 1200 dan, and when the circumferential direction of the tubular body 10 is flattened, The first wire body 11 and each of the third wire bodies 13 are respectively at an angle of -45 degrees with the axial direction, and each of the second wire body 12 and each of the fourth wire bodies 14 are respectively at an angle of +45 degrees with the axial direction.

In addition, at least one of the first wire body 11 (preferably having at least two of the first wire body 11) extends between the third wire body 13 and the third wire body 13 adjacent to one side thereof, and the other side There is no one of the first linear bodies 11 extending between the adjacent third linear bodies 13 , in other words, there is an array of adjacent third linear bodies 13 without the first linear body 11 therebetween, so that the two third linear bodies 13 of the segment Generally speaking, the second line body 12 and the third line body 13 have different deniers and outer diameters. When braided into a tubular shape, the two third line bodies 13 and the fourth line body 14 intersecting therewith It will be prominently highlighted. In contrast, the first wire body 11 and the second wire body 12 are less noticeable, so that the overall appearance has a substantially uneven block-like appearance, especially after the second wire body 12 passes through the third wire body 13. The side (the inner side of the tubular body 10), that is, at the center of the block unit, causes the two adjacent third wire bodies 13 and the two fourth wire bodies 14 intersecting there to form a rhombic block-shaped convex portion, tubular The body 10 as a whole has a plurality of diamond-shaped block-like projections arranged neatly.

With the above structure, the shoelace provided by the present invention can prevent looseness due to the uneven surface formed by the block-like convex portions. In particular, the shoelace of the present invention is composed of a hollow tubular body and has a large deformation space. It can be firmer when knotted; in addition, the more prominent part is made of polyester fiber. Because polyester fiber has the characteristics of easy dyeing and processing, the overall appearance of the shoelace can be made of polyester fiber. To adjust, the linear body of the thermoplastic polyurethane elastomer plays the role of weaving and maintaining the shape, but because the outer diameter is small and concave, the relative is not obvious, the part of the polyester fiber line seems to float, and Provides a great three-dimensional feel.
