Description

TECHNICAL FIELD The present invention relates to a shoelace (hereinafter also referred to as "lace") holder capable of holding an excess portion of the shoelace, and more specifically, a knot made of urethane, silicone rubber, or the like. To provide a shoelace holder capable of holding a surplus part even when a difficult lace is used and always lifting up the tongue of a shoe.

In general, as shown in FIG. 6, lace-up shoes are constructed by providing shoelace holes 12 provided at the left and right edges of an opening 11 in the upper portion and a shoe tongue 13 covering the opening 11. When wearing such a lace-up shoe 1, the shoelace is passed through the shoelace hole 12 and the lace insertion portion 15 provided on the upper surface of the shoe tongue 13, and after tightening the lace according to the shape of the foot, the shoe is put on. The surplus portion remaining from the lace hole 12 is held by a bow or the like and used.

By the way, when putting on and taking off such lace-up shoes, it is necessary to loosen the laces or to tie the laces. . In addition, there is a problem that an assistant is required especially when an elderly person or a handicapped person uses the apparatus.

In response to this, a method has been proposed in which elastic materials such as urethane and silicone rubber are used for such cords to make it easier to put on and take off the shoes, and to allow the feet to be tightened appropriately (patented Reference 1).

International publication WO2016/162651

However, the use of elastic materials such as urethane and silicone rubber causes the following problems.

In other words, elastic materials such as urethane and silicone rubber cannot be used for tying bow ties, etc., because they have a smooth surface and are harder than cloth strings, unlike cloth strings. .

In addition, a cord with a circular cross section, such as urethane or silicone rubber, often has a large diameter with respect to the inner passage of the cord insertion portion of the shoe tongue, making it difficult to pass through the cord insertion portion. For this reason, there are cases where the lace is not passed through the lace insertion portion, but if the lace is not passed through the lace insertion portion in this way, the shoe tongue will fall under its own weight, and the shoe tongue must be lifted by hand when putting on the shoes. Since it is necessary to wear them, there is a problem that wearing shoes becomes troublesome.

In addition, urethane or silicone rubber cords are harder than cloth material cords, so excessive cords may protrude upwards or laterally, causing problems such as obstructing walking and unsightly appearance.

Therefore, the present invention has been made by paying attention to the above problems, and even if a string made of elastic resin such as urethane or silicone rubber is used, the surplus string can be easily held. To provide a shoelace holder capable of lifting a shoe tongue upward at all times to make it easy to put on, and preventing a surplus part of the lace from becoming an obstacle.

That is, the shoelace holder of the present invention is a shoelace holder used for shoes having a shoelace hole and a shoe tongue, and is used for a shoe having a shoelace hole and a shoe tongue. It is sandwiched between an upper piece and a lower piece rotatably provided so that the tip side opens and closes, and the upper piece and the lower piece, and opens and closes between the tip side of the lower piece. and an intermediate member provided rotatably, and by rotating the upper piece to the lower piece side and pressing the intermediate member with the upper piece, excess space is formed between the upper piece and the intermediate member. A clamping portion for clamping and holding a string is configured, and a shoe tongue attaching portion for clamping and holding the shoe tongue between the intermediate member and the lower piece pressed by the rotation of the upper piece is configured .

Further, in such an invention, the intermediate member has an L-shaped bent portion, the lower piece has an upright portion that rises toward the upper piece, and the bent portion is , is accommodated in the back of the standing portion and rotated about the upper end of the standing portion.

According to the present invention, even when a string made of elastic resin such as urethane or silicone rubber is used, the string can be easily held, and the shoe tongue mounting portion is provided. So, the shoe tongue can always be lifted upwards to make it easier to wear. In addition, it is possible to hold the lace and attach it to the shoe tongue at the same time, thereby saving time and effort when putting on the shoe.
