Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an unraveling prevention device for shoelaces.

(Prior art) According to Japanese Utility Model Publication No. 14442/1987, a metal or synthetic resin main body having four through holes and a lid are used as a hinge, and a tongue piece of the lid is hooked to a notch in the main body. A shoelace loosening fitting is disclosed, which is made by attaching a hook and loop fastener to the upper part of the tongue of the shoe, attaching the lower part of the hook and loop fastener to the bottom of the hook and loop fastener, and cutting out the inside of the hook and loop fastener. A device for preventing loosening of shoelaces is disclosed.

(Problems to be Solved by the Invention) The former described in the above-mentioned conventional technique is described in the same bulletin as such that the shoelace is passed through a through hole provided in the main body and the entire shoe is fixed to the shoe. Not only is this inconvenient because it requires the work of passing the string through the hole or pulling it out, but it is also difficult to use, and since the main body is made of a hard material such as metal, it can be used to hold the laces of the wearer's pants and shoes. It has undesirable defects such as being easily damaged.

Similarly, the latter has a hook-and-loop fastener attached to the tongue of the shoe and is integrated with the shoe.
It is unsuitable for consumers who do not need a device to prevent shoelaces from loosening, and manufacturers in particular have to manage the production of both shoes with and without devices to prevent shoelaces from loosening, and retailers must also manage the production of both shoes. This is not only desirable in terms of logistics management as it requires a large space to display shoes in stores, but it also has defects such as the lower hook and loop fastener does not have a cutout, making it thicker when in use. .

Further, both the front and rear parts require a step of attaching the upper member to the lower member with a hinge or sewing, which takes time and effort to manufacture.

There is a tendency for users to prefer products that are simple, easy to use, and easily available at low prices.

This invention simplifies logistics management by providing a single item separately from shoes, makes it convenient to use without passing a string through the hole, prevents damage to other items, and provides a separate product separately from shoes. It is a new product that fits the consumer's psychology by making it possible to obtain and enjoy it as desired, reducing the burden on shoe manufacturers and shoe retailers, preventing it from becoming too thick when used, and reducing the manufacturing process. The object of the present invention is to provide a device for preventing unraveling of shoelaces.

(Means for Solving the Problems) In order to achieve the above object, the shoelace unraveling device according to the present invention is made of similar materials such as leather, synthetic resin, cloth, etc. A large, seamless frame-shaped substrate that can be folded into two is constructed, and locking portions are provided at both end sides of the substrate so that they can be locked to each other.

(Embodiment) The embodiment shown in Fig. 1 is a rectangular frame shape that can be folded in half at the middle of both long sides 1 and 1', and has an inner diameter hole larger than a shoe knot. Attach female and male hook-and-loop fasteners 4, 4' to the inside of the short sides 3, 3', and attach parts 5, 5', 6, on both sides of the knot to the bi-fold line on the long sides 1, 1'.
6'.

In addition, as is clear from the figure, in the embodiment shown in FIG. 2, both ends of the substrate 2 are made slightly thinner, and a non-slip 7 consisting of a group of small protrusions is formed on the inner surface of the parts 5, 5', 6, and 6' for suppressing knots. It has been established.

This invention uses synthetic resin, cloth, etc. as the substrate material, attaches decorations, pictures of idols, aroma dispersion devices, etc. to the exposed parts of the substrate, and uses hooks and pressure-sensitive adhesives instead of hook-and-loop fasteners. This may be done using adhesives, clips, etc. Moreover, the shape of the substrate can also be made into another suitable shape.

(Function) As shown in FIGS. 3 and 4, the shoelace tying ball 9 is inserted into the inner diameter hole of the base plate 2, and both sides of the tying ball 9 are held at the parts 5, 5', 6, and 6'. The unraveling preventive device of the present invention is used with the hook-and-loop fasteners 4 and 4' in the locked state after the shoelaces are held in place, and the preventive device is highly effective in completely preventing shoelaces from unraveling. It is.

(Effect of the invention) The shoelace unraveling prevention device according to the invention is used as described in the above operation, and
It is provided through a separate route from shoes, so it does not complicate the logistics management of shoes, and it does not have the inconvenience of passing laces through holes as in the former case.
Furthermore, since it is constructed using soft materials such as leather, synthetic resin, and fabric, it does not easily damage the hem of pants, etc., and as mentioned above, it is sold separately from shoes, so consumers can use it as accessories. Not only does it have the advantage of being available and enjoyable depending on one's taste, but it does not affect shoe production management or consideration of shoe display space, so it does not place much of a burden on shoe manufacturers or shoe retailers. Furthermore, when in use, the upper and lower surfaces 12 and 13 of the shoelace knot 9 are inserted into the inner diameter hole of the base plate 2 (see FIG. 5), so there is no danger that the shoelace will become even thicker. Moreover, since the board is in the form of a seamless frame that can be folded into two, there is no need for the process of fixing it with hinges or sewing as in the conventional example, and the structure is easy with fewer steps. .
