Description

Anti-loose lace

The present invention relates to a shoelace that prevents loosening of the tie.

After the tie-up of the conventional shoelace, it is easy to loosen and cause inconvenience and danger if it is pulled by external force. In order to avoid the slippage of the shoelace easily, many types of anti-slip lace-removing structure are disclosed in the prior art, for example, patent TW479474, TWM240854, TWM253245 and TWM337982 disclose that a solid shoelace is provided with a thick section and a thin section (also a flat section) spaced apart from each other. If the knot is tied in a thin section, when the external force is pulled, the thick section is subjected to a thick section. Further, it is defined that the density of the thin sections is larger than that of the thicker sections, as described in the TWM339939 and US Pat. No. 5,946,779.

However, each of the above structures has the following problems: First, the thick section and the thin section of the interval arrangement make the appearance of the shoelaces undulate, which affects the appearance beautifully; furthermore, since several thick sections need to be set, the weaving material of the shoelace must be more Generally, there are more uniform laces, which is a waste of cost. Finally, it is more difficult and time-consuming to weave the small shoelace when it is large. If the density is different, the difficulty of weaving is added. In addition, due to the thick section The same length of fabric is woven with the same amount of fabric at different densities, which makes the thick section easier to be compressed. Even if it is tied to the thin section, the thick section is easily compressed and slipped off.

In addition, US Pat. No. 3,110,945 discloses a structure in which the appearance is less than the difference in thickness, and an inner core is disposed in a hollow outer layer, and the inner core is provided with a plurality of convex portions at intervals. For example, it is directly knotted with the inner core, and also achieves the thickness stop effect as in the aforementioned patent. However, such a structure requires time and effort to knot the inner core one by one to form the convex portions, and the process is complicated and convex. The size of the core is limited by the size of the core itself and cannot be changed as needed.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a shoelace that prevents slipping of the tie and can have a flat appearance.

To achieve the above object, the present invention provides an anti-loose shoelace comprising an outer sleeve and an inner core.

The outer sleeve is woven from a fabric and forms a cavity. The outer diameter of the outer sleeve is substantially constant along a length thereof. The inner core is disposed in a cavity of the outer sleeve, and the inner core is a plurality of strips. Weaving a woven thread, wherein the woven threads comprise at least one first woven thread and a plurality of second woven threads, the at least one first woven thread comprising a plurality of bonding sections and a plurality of intervals arranged along the length direction thereof The second woven thread is woven together with each of the at least one first woven thread to form an enlarged portion, such that an outer diameter of each of the enlarged portions is larger than an outer diameter of each of the spaced portions. And the number of the woven threads included in the radial section of each of the enlarged portions is greater than the number of woven wires included in the radial section of each of the first woven lines, but the outer diameter of each of the expanded portions is smaller than the inner diameter of the outer sleeve.

With the above structure, the spacer segments have a smaller outer diameter because they are not woven with the second weaving thread, so the distance between the spacer segments and the inner wall of the outer sleeve is larger than the enlarged portions and the outer sleeve. The distance between the inner walls of the tube provides a space for compression inward. When the user can tie the knots with the interval sections, the larger outer diameter can be used to avoid slipping. The effect of the detachment, and the inner core of the invention is completely woven directly from the fabric, and it is not necessary to additionally tie the inner core or provide the protrusion on the inner core, which is convenient to manufacture, and further, the anti-looseness provided by the invention The shoelace has a flat appearance and is similar to the general shoelace, and has the convenience of beauty and tie.

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 , FIG. 2 and FIG. 2A , the present invention provides an anti-loose shoelace 10 comprising an outer sleeve 11 and an inner core 12 .

The outer sleeve 11 is woven by a fabric and defines a cavity 111. The outer diameter of the outer sleeve 11 is substantially constant along the length thereof. The inner core 12 is disposed in the cavity 111 of the outer sleeve 11 . The inner core 12 is woven by a plurality of woven threads, wherein the woven threads comprise at least one first woven thread 121 and a plurality of second woven threads 122, and the at least one first woven thread 121 is spaced along its length. a plurality of bonding sections and a plurality of spacing sections, wherein the second woven lines 122 are woven together with the bonding sections of the at least one first woven thread 121 to form an enlarged portion 123, so that each of the enlarged portions The outer diameter of 123 is larger than the outer diameter of each of the interval segments, and the number of threads included in the radial section of each of the enlarged portions 123 is greater than the number of threads included in the radial section of each of the first wires 121, but The outer diameter of each of the enlarged portions 123 is smaller than the inner diameter of the outer sleeve 11. Preferably, the threads The plurality of first woven lines 121 and the plurality of second woven lines 122 are wound and woven with each other before being woven with the second woven lines 122.

In the main embodiment of the present invention, each of the enlarged portions 123 has a tail portion 1231 at opposite ends of the lengthwise portion, and a central portion 1232 between the two tail portions 1231. The at least one first thread 121 is in the respective The tail portion 1231 is wrapped around the second woven lines 122. The at least one first woven line 121 is wrapped in the second woven lines 122 at the central portion 1232 and is covered by the second woven lines 122. The winding is further formed into a relatively tight structure at the tail portions 1231, but a bulky and wide structure is formed at the central portions 1232, and the effect of avoiding slippage is better by the method of winding the knitting.

When the first weaving wires are woven along the length direction thereof, the second weaving wires are woven together with the first weaving wires for a predetermined distance, and the second weaving wires are cut off, and the knitting is continued. The first weaving lines (forming the spaced sections) are woven for a predetermined distance and then weaved together with the second weaving lines to form the inflated portions, weaving together a predetermined distance and then cutting off, and so on. That is, it can be finished mechanically quickly and accurately.

In actual use, please refer to FIG. 1 , FIG. 2 and FIG. 2A and with reference to FIG. 3 and FIG. 3A , when the user performs the shoelace stretching and binding action on a shoe body 20 , the anti-loose can be released. The portion of the shoelace 10 that does not have the enlarged portion 123 (that is, the spaced portion of the first thread 121) is disposed at the lace hole and the tying portion 101, and the portion of the detachable shoelace 10 that does not have the enlarged portion 123 is received. The pressing of the lace hole or the compression of the binding portion will be compressed and flattened to achieve the effect of tight binding, and the pulling of the external force will be restricted by the enlarged portion 123 to prevent the anti-loose shoelace 10 from sliding and loosening.

With the above structure, the anti-loose shoelace provided by the invention can effectively prevent the shoelace from binding Looseness causes the user's safety risk, and it has the same flat appearance as the general shoelace, which does not cause the knotting process to be unsmooth. More importantly, since the inner core is completely woven by the fabric, it is more Soft, on the other hand, the invention does not require time-consuming and labor-intensive knotting of the woven wire to form a convex portion or to place a convex piece inside the outer sleeve. Conversely, the inner core of the present invention is directly woven and wound without any other processing, and is inflated. The length and spacing of the department can even be set by computer, which is conducive to fully automatic machine manufacturing, low cost and good yield, and has a progressive effect.
