Description

  The present invention relates to a shoelace that is woven using a non-stretchable woven yarn and a woven yarn having a non-slip function, and that does not easily unravel during wearing, and a shoe including the shoelace.

  Conventionally, most of the shoelaces in sports shoes, sneakers, walking shoes, business shoes, and other shoes are woven only with non-stretchable non-stretch yarns, which are inserted sequentially from the eyelet holes on the toe side. It was used in such a way that it was fastened with a ribbon knot (bow) near the mouth or ankle, thus fitting the shoe to the foot.

  However, the conventional method of tightening shoelaces has the following problems.

  In other words, the knot of a shoelace may loosen or unwind before it is noticed while exercising or walking, and each time the shoelace must be retightened or re-tied. (The first problem).

  Also, because I was walking without noticing that the shoelaces were untied, there was often a risk that oneself or someone else would step on the untied shoelaces and fall down, sometimes leading to an unexpected accident. Etc. (second problem).

  There were also problems (third problem) in which sports athletes felt unhappy by unwinding their shoelaces during the competition and making play mistakes, or interrupting play and lowering their rankings.

  Also, if there is a heel of the dominant arm in how to fasten or insert the shoelace, the length of the tied shoelace will not align in time, and only one shoelace will become longer after tying, There was a risk (fourth problem) of stepping on the shoelace and falling.

  In addition, it is quite time-consuming to fold and adjust shoelaces with both hands, and even a healthy person feels that it is quite a troublesome task, even the elderly, the handicapped person, the body For people with disabilities, it has been a considerable burden to tie shoelaces and adjust the degree of tightening frequently (fifth problem).

  On the other hand, despite the fact that the shoes are designed and manufactured to fit the feet for the sake of health, the shoelaces may be loosely tied for ease of wearing and removing operations for the reasons described above. Or crushed the heel like slippers. If you wear a shoelace that has been tightened inadequately like this, the toes of the foot may become clogged at the tip of the shoe, or the foot may not be firmly fixed in the shoe. The position and height of the arch and the arch support of the shoe do not match, so-called foot swims in the shoe. If you keep wearing such a state for a long time, it may cause adverse effects on the body, such as causing hallux valgus and hammer finger syndrome, as well as protecting the foot correctly. (Sixth problem).

Incidentally, in order to make it easy to take off and put on, a shoe with a rubber string as a shoe has been disclosed in the past (refer to Patent Document 1), but this actively uses the elasticity of the rubber strap. It is a thing, and it does not utilize the difficulty of sliding unique to rubber.

  The shoe lace according to claim 1 is to solve the problems of the conventional shoe lace by skillfully utilizing the inherent slip resistance such as rubber, in view of the above-mentioned situation, An object of the present invention is to provide a new shoelace which is devised so as not to be unwound or loosened while walking.

  The shoelace according to claim 2 is intended to further enhance the function of preventing the shoelace from being unwound or loosened during walking.

  The shoelaces according to claims 3 and 4 are intended to be easily and easily implemented at low cost.

  The shoe according to claim 5 is intended to provide a new shoe in which the shoelace does not come loose or loose during walking.

  In order to solve the above problems, the polisher according to claim 1 is a shoelace woven using a non-stretchable non-stretchable yarn, and has a non-slip function on the surface of the portion forming the knot. It is characterized by being woven in a state where it is exposed in a scattered arrangement.

  Similarly, the shoelace according to claim 2 is characterized in that each exposed portion of the woven yarn having a non-slip function is woven in a convex shape.

  Similarly, the shoelace according to claim 3 is characterized in that the thread having a non-slip function is a bare thread of synthetic rubber or raw rubber.

  Similarly, the shoelace according to claim 4 is characterized in that the bare yarn is polyurethane.

  Similarly, a shoe according to a fifth aspect includes the shoe lace according to any one of the first to fourth aspects.

  That is, the shoe lace according to the present invention and the shoe provided with the shoe lace maintain the fit to the foot of the shoe when a knot such as a ribbon knot (bow) is formed in use. Therefore, the woven yarn having the anti-slip function prevents the looseness and unraveling of the knot and prevents the anti-slip function.

  In addition, each exposed portion woven into a convex shape of a woven yarn having a non-slip function more effectively prevents loosening and unraveling of the knot.

  Furthermore, bare yarn of synthetic rubber such as polyurethane or raw rubber eliminates loosening and unraveling of the knot and facilitates production, thereby enabling cost reduction and the like.

  The polisher according to claim 1 is a shoelace woven using a non-stretchable non-stretchable woven yarn, wherein the knitted yarn having a non-slip function is scattered on the surface of the portion forming the knot. It is characterized by being woven into an exposed state, and by using skillfully the difficulty of slipping inherent to rubber, etc., the problems of the above-mentioned conventional shoelaces have been solved. Thus, it is possible to provide a new shoelace which is devised so as not to be unwound or loosened during walking.

  The shoelace according to claim 2 is characterized in that each exposed portion of the woven yarn having a non-slip function is woven in a convex shape, so that it does not come loose or loose during walking. Can enhance the function.

  The shoelace according to claim 3 is characterized in that the thread having the anti-slip function is a bare thread made of synthetic rubber or raw rubber, and can be easily and easily implemented at low cost.

  The shoe lace according to claim 4 is characterized in that the bare yarn is polyurethane, and can be easily and easily implemented at low cost.

  A shoe according to claim 5 is provided with the shoelace according to any one of claims 1 to 4, so that the shoelace is not unwound or loosened during walking. Can provide.

  A first embodiment according to the present invention will be described with reference to FIGS.

  Reference numeral 1 in the figure denotes a shoelace according to an embodiment of the present invention. A shoelace 1 according to this embodiment is formed of a braid using a polyester multifilament yarn 2 that functions as a non-stretchable woven yarn and a polyurethane monofilament bare yarn 3 that functions as a woven yarn that performs a non-slip function. The terminal member 4 which forms the rigid part for stringing is attached to the both ends.

  The shoelace 1 is composed of a braid 5 for braids by gathering together a polyester multifilament yarn 2 and a polyurethane monofilament bare yarn 3 in a 9: 1 ratio. It is obtained by knitting the knitted bundle 5 in a braid shape.

  The distribution of the number of the polyester multifilament yarn 2 and the polyurethane monofilament bare yarn 3 described above is determined by the characteristics of the material such as hardness and elongation, the type of shoes, the braiding method, etc. The invention is not necessarily limited to the above 9 to 1, and a shoe lace may be knitted by a combination of a braided braid without a single polyurethane monofilament bare yarn 3 and a braided braid with at least one braid. If so, it may be implemented by increasing the number of lines a little. In short, it is important to knitting a satisfactory number of polyurethane monofilament bare yarns 3 by experimentation and the like, and this should loosen and prevent unraveling as much as possible.

  It is more effective that the bare yarn 3 is woven in a convex shape on the outer surface of the string main body. This convex weaving state can be easily carried out by placing the polyurethane monofilament bare yarn 3 entangled with the polyester multifilament yarn 2 in advance before forming the braided bundle 5 for braiding. In this way, the outer surface of the string main body can be made small and uneven, which is effective.

  Next, a second embodiment according to the present invention will be described with reference to FIG.

  The shoe 6 according to the second embodiment shown in FIG. 4 is one to which the shoelace 1 according to the first embodiment is attached.

  As described above, when the shoelace 1 according to the first embodiment is attached to the shoe body 7, the polyurethane monofilament bare yarn 3 is pressed against the cut edge of the eyelet hole 8 so that it is more difficult to loosen and unravel. Is convenient.

  The above-mentioned woven yarn having an anti-slip function can be woven in a state where it is exposed to an arrangement scattered on the surface of a portion that forms a clog when worn. Each exposed portion of the woven yarn having a non-slip function can be woven out in a non-convex state. The woven yarn having a non-slip function can be woven in a convex shape without being entangled with the non-stretchable woven yarn. The yarn having the anti-slip function can be woven by using a multifilament bare yarn. The bare yarn can be made of synthetic rubber or raw rubber other than polyurethane. The braids can be woven with round string or flat string. In this case, it is optional to insert a strong core for reinforcement.

It is a front view which shows a part of 1st Embodiment which concerns on this invention. It is explanatory drawing which similarly shows a structure. It is an expanded cutaway end view which follows FIG. 2A-A line. It is a perspective view which shows a part of 2nd Embodiment which concerns on this invention.
