Description

[Detailed description of the invention] [Field of industrial application] This invention is attached to shoes such as athletic shoes, sneakers, and mountain climbing shoes to allow shoelaces to pass through. This is a string threader that is sewn onto the opening of the string.

[Prior art and its problems] Conventionally, this type of device has a string hook in which a plurality of string loops are integrally connected at one end of the mounting side, as shown in Japanese Utility Model Application Publication No. 51-130252. It was hot with ingredients.

However, since this shoe has a lace loop protruding from one side of the attachment side, in order to attach it to the shoe, attach the attachment side to the opening edge of the forked opening of the shoelace, and then Since the threading rings protrude inside the opening, the two opposing string threading rings butt against each other, reducing the tightening effect.
The opening must be made wider. When the opening is widened, it becomes easier for dirt, gravel, etc. to enter the shoe through the opening, and since it is attached only on one side, there is a risk that it will come off if a tightening force is applied to the other side.

[Means for Solving the Problems] In order to solve the above problems, the present invention has a synthetic resin substrate having a thick wall approximately in the center, and two rows (levels) of upper and lower layers in the thick part. A large number of holes are made for the string to pass through, and a sewn part is provided on the outer periphery of the thick part.

[Function] There are two rows (tiers) of string holes, upper and lower, so you can select and use the holes depending on the strength of the tightening, and there is a sewing part on the periphery, so the installation (sewing) is strong. be.

[Example] An example of implementing the present invention will be explained with reference to the drawings. The synthetic resin substrate A is made of any synthetic resin such as vinyl chloride resin, polyamide resin (nylon), phenol resin, urea resin, etc. It is on a flat plate with a roughly rectangular shape that is hard enough to have shape retention and can be sewn to the bifurcated skin b that opens oppositely in a forked shape. A thick part 1 is formed, and a sewn part 2 is provided on the outer periphery, and string passage holes 3 and 4 are alternately opened in two rows (rows) of upper and lower parts along the length of the thick part 1. .

The thick part 1 has approximately the same shape as the substrate A, with a thick center part, and a large number of string passage holes 3 and 4 are bored in the thick part 1, and a string b or a string b is formed in the thick part 1. The thick part 1 is fitted into the fitting hole c opened in the decorative piece b' to expose the shoe passage holes 3 and 4.

The sewing part 2 is for sewing the board A onto the flap b or the decorative piece b' using a sewing machine or the like, and is protruded like a brim from the outer periphery of the board A, that is, the periphery of the thick part 1.
After fitting the thick part 1 into the fitting hole c, this sewn part 2
is brought into contact with the back surface of the flap b at the edge of the fitting hole c or inserted between the flap b and the decorative piece b', and these are sewn together.

A large number of string passing holes 3 and 4 are formed in parallel in the upper and lower rows along the long side of the thick part 1 of the board A, and either one or both of the holes 3 in the upper row or the holes 4 in the lower row are formed. Select the appropriate tightening position and strength to insert the shoelace. The string passing holes 3 and 4 can be made not only in a zigzag shape by shifting the upper and lower positions from each other as shown in the figure, but also in two stages at the same position, and the shape of the holes is also as shown in the figure. , triangular shapes with opposite directions, for example, with the apexes facing each other, or conversely with the bases facing each other. Also, by tapering the rim so that the surface slightly expands relative to the wall thickness, it becomes easier to pass the string through.

Although the shape of the substrate A is slightly inclined on both short sides as shown in Fig. 1, it can also be made straight or curved, or tapered on the long sides as shown in Fig. 3. For example, it is optional to form one side narrower on the toe side and slightly wider on the other side, and the overall shape is determined by selecting an appropriate shape such as trapezoid, ladder shape, rhombus shape, or a slightly modified shape of these. The design should not be limited.

In addition, although the string passage holes 3 and 4 have been described as two rows (upper and lower rows), the upper rows (rows) are those located on the sides facing each other at the opening of the string b, as shown in FIG. 4, that is, on the inside. , the lower row (row) is the one on the outside. Therefore, when attaching to shoe B, two identical ones may be used, but it is better to attach two sets of symmetrically formed ones for better appearance.

[Effects] The present invention has a thick wall at approximately the center of the synthetic resin substrate, and a large number of string holes are drilled in the thick wall in two rows above and below, and a sewn part is provided on the outer periphery of the thick wall. When sewn to the shoelace, the entire circumference is sewn, so it can be attached strongly, and it will not come off even if the shoelace is tightened. Moreover, since a fitting hole corresponding to the size of the thick part is drilled in the flap, there is no need to widen the forked opening, and there is little risk of dirt or gravel entering.

Furthermore, since there are two rows of lace holes in the upper and lower rows, you can select the upper or lower row of holes depending on the area to be tightened, and for example, since the laces are often tightened or loosened on the shoe opening side, the contact area is prone to slipping. Make it straight, for example, at the base of a triangle as shown in the figure, so that the string can easily slide around the edges of the hole, and make it easier to tighten, and on the toe side, make it less likely to slip, for example, at the apex of the triangle as shown in the figure. This prevents the strings from slipping and makes it possible to tighten them strongly, and by appropriately forming these on the upper row side or the lower row side, it is possible to use them depending on preference and purpose.
