Description

  The present invention relates to a shoelace guide that can easily pass through an end portion of a wire-like shoelace, can easily hold a loose shoelace, and can prevent the tightened shoelace from being bent strongly.

  Conventionally, shoes and medical instruments that can easily tighten or release a string by operating a winding device capable of winding a wire-like string have been proposed, and a shoe equipped with the winding device. For example, various types of string guides are used to guide a string through a predetermined position such as a shoe (Patent Documents 1 to 4).

A string guide 50 shown in FIG. 4A, which is a form that has been widely used in the past, has a shoelace W inserted through an elongate tubular passage curved in a substantially U shape (Patent Documents 1 and 2). .
Further, as shown on the right side of FIG. 4B, there is proposed a string guide 51 in which an elongated tube-shaped passage is substantially linear (Patent Document 3).

  The conventional string guides 50 and 51 have a problem that it is difficult to perform the operation of passing the end portions of the strings because the openings at both ends of the passage are small. Such a problem becomes even more pronounced when the passage is curved in a U-shape, adding resistance when the string is bent.

  Therefore, as shown on the left side of FIG. 4 (B), a string guide 52 (Patent Document 3) with an enlarged opening at both ends of the passage through which the string passes, and a string guide 53 shown in FIGS. 4 (C) to (E), As shown in Fig. 54, there has been proposed one provided with a passage opened by removing the wall surface on the side where the shoelace W does not contact when the shoelace W is tightened (Patent Documents 1 and 4).

Shoelace guide. "And an embodiment described below It can be suitably embodied by etc..

Hereinafter, an embodiment of a shoelace guide embodying the present invention will be described.
As shown in FIGS. 1 to 3, a shoelace guide 10 according to an embodiment of the present invention is nylon or polychlorinated having strength and abrasion resistance for inserting and guiding a wire-like shoelace W. It is integrally formed of a resin material such as vinyl, and has a horizontally long substantially trapezoidal main body 1 and a square plate-shaped mounting portion 2 for sewing and fixing the main body 1 to the back of a shoe S or the like. And.
And the said main-body part 1 is equipped with the opening 3a in the both ends of the longitudinal direction, and is equipped with the elongate tunnel-shaped channel | path 3 which can penetrate the said shoelace W. FIG.
The mounting portion 2 is provided so as to extend from the lower edge of the main body portion 1 on the side where the shoelace W does not contact when the shoelace W inserted through the passage 3 is tightened. Furthermore, it is formed in a thin plate shape curved so as to follow the surface shape of the upper part of the shoe S.

When the shoelace W inserted through the passage 3 is tightened, the side wall of the passage 3 on the side where the shoelace W does not contact has a linear inner surface 4, and the shoelace inserted through the passage 3. The inner surface 5 of the side wall of the passage 3 that is in contact with the shoelace W when W is tightened is formed shorter than the linear inner surface 4, and the upper and lower wall surfaces 6, 7 of the passage 3. Is extended outward from both longitudinal ends of the inner surface 5 of the side wall of the passage 3 on the side where the shoelace W comes into contact, and extends so as to cover the entire area of the linear inner surface 4.
Therefore, it is possible to secure a wide area that can cover and protect the shoelace W.

Here, the dimensions and material of the main body 1 of the shoelace guide 10 can be changed as appropriate based on the magnitude of the force applied to the shoelace W and the design reason depending on the type and application of the shoe S. .
As an example, when the shoelace guide 10 is made of a resin such as nylon, polybutylene terephthalate, or polycarbonate when used for a golf shoe for men, the length of the linear inner surface 4 of the side wall of the passage 3 is: The size may be about 12 mm, but may be larger, and can be appropriately selected from a size up to about 35 mm, for example.

Furthermore, in the shoelace guide 10 of the present embodiment, when the shoelace W inserted through the passage 3 is tightened, the inner surface 5 of the side wall of the passage 3 on the side where the shoelace W comes into contact is an arcuate inner surface. It is set to 5.
The arcuate inner surface 5 is not limited to a portion passing through the inside of the passage 3 so that the shoelace W is pulled out of the passage 3 at an obtuse angle even when the shoelace W is tightened. The shoelace W is formed of a gently curved surface so that the shoelace W is not strongly bent even in the vicinity of being pulled out from the opening 3a.
In order to obtain the above effect, the central angle θ of the arc that constitutes the arc-shaped inner surface 5 of the present embodiment is specifically set to about 50 degrees. As an embodiment of the present invention, The central angle θ is preferably in the range of 20 degrees to 130 degrees, and more preferably in the range of 30 degrees to 80 degrees.

In the present embodiment, the upper and lower wall surfaces 6 and 7 of the passage 3 are widened so as to expand outward from both longitudinal ends of the linear inner surface 4.
That is, the lengths of the upper and lower wall surfaces 6 and 7 are formed longer than the length of the linear inner surface 4, and the main body 1 is substantially trapezoidal.
Therefore, even if the shoelace W is loosened, it is possible to prevent the shoelace W drawn from the opening 3a of the passage 3 from spreading out upward or downward.

Further, the upper and lower wall surfaces 6 and 7 of the passage 3 are formed flat so as to extend in the horizontal direction, so that the openings 3a at both ends of the passage 3 are kept wide.
Moreover, as a wire-like shoelace W that can be suitably used with the shoelace guide of the present invention, one having a diameter of about 0.6 to 1.2 mm is preferable, and the passage 3 is also in the narrowest portion. A transverse cross section sufficiently larger than the diametric cross section of the shoelace W (that is, a size having at least the diameter of the shoelace W + 0.2 mm in the narrowest portion so that the wire-like shoelace W can pass without resistance). It is good to have.
Furthermore, the width | variety of the said channel | path 3 is good in the width | variety of the shoelace W being +0.6 mm or less.

The shoelace guide 10 configured as described above can be easily manufactured using a mold for resin molding, and the mounting portion 2 is arranged and sewn so as to be hidden behind the upper side of the upper portion of the shoe S. Thus, it can be easily fixed to the shoe S.
In addition, since the shoelace guide 10 of this embodiment is made into the left-right symmetric shape, it can be used for the left-right side of the back part of the shoe S.
Further, the shoe S is provided with a shoelace winding device 20 having a reel for winding the shoelace W therein and a disc-like handle for rotating the reel, and is fixed to the shoe S. Both ends of the string W are fixed to the reel.

And in the shoelace guide 10 of this invention, the opening 3a of the both ends of the channel | path 3 is large open, the channel | path 3 has the linear inner surface 4, and the upper and lower wall surfaces 6 and 7 are horizontal. Since it is formed flat so as to extend, the end portion of the shoelace W can be passed straight and smoothly from the opening 3 a at the end portion in the longitudinal direction of the main body portion 1.
Therefore, in the shoelace guide 10 of the present invention, it is possible to quickly perform even a fine work of inserting the shoelace W through the plurality of small shoelace guides 10.

In the shoelace guide 10 of this embodiment, the normal pulling force (150 N) for tightening the shoelace W is used for the test by setting the central angle θ of the arc constituting the arc-shaped inner surface 5 to about 50 degrees. 2, the shoelace W is not bent at a right angle even when applied in a direction orthogonal to the linear inner surface 4 of the passage 3, and the shoelace W is obtuse. It was pulled out of the passage 3 while being bent while maintaining a gentle curve, that is, a natural R shape.
Here, the shoelace W used in the above test was processed with a swaging machine on a wire rope in which 49 stainless steel wires with a diameter of 0.11 to 0.13 mm were twisted and covered with nylon resin. The shoelace W having a diameter of about 0.9 mm.
