Description

  The present invention relates to a shoelace threader that is a tightening tool for a shoelace.

  The lace shoe has a plurality of holes (eyelets) through which the shoe lace is passed from the toe side to the ankle side in two rows in the upper part (upper) that rises from both sides (hereinafter simply referred to as “shoes”). ) Refers to “shoelace”, and simply referred to as “string” refers to “shoelace”. Usually, the laces are passed directly through the eyelets, but for the purpose of facilitating the passing of the laces and enhancing the decoration effect, etc., shoelace passers that are attached to the eyelets and have holes for passing the laces are used. Yes.

  Patent Document 1 describes a shoelace threader composed of a male screw, a washer, and a female screw. A circular pedestal is provided at one end of the male screw. The washer is a plate-like member, provided with a first hole through which the male screw passes in the center and a second hole through which the string passes at a position shifted from the center. This shoelace threader has a male screw threaded through the eyelet from the inside of the shoe, a male screw threaded through the first hole of the washer from the outside of the shoe, and a female screw tightened with the male screw. It can be attached to shoes by sandwiching or cloth. The shoe is fixed to the foot by passing the string through the second hole and then tying the string in the same manner as when passing through the eyelet directly. Further, in this document, it is said that the decoration effect can be enhanced by attaching a flower, a character model, or a jewel to the upper part of the female screw.

JP 2000-354504 A

  The size of the male thread, female thread, and washer of the shoelace threader described in Patent Document 1 is several millimeters whose outer diameter is slightly larger than that of the eyelet, and the height is several millimeters at most from the male thread and female thread. The size of the washer is about 1 mm or less. For this reason, the shoelace threading device described in Patent Document 1 cannot be used unless the three parts such as the small male screw, the washer and the female screw are assembled as described above, and the mounting work is troublesome.

  Further, the portion around the second hole protrudes outside the female screw in order to pass the string through the second hole, so that it is easily caught by human eyes during use. Unlike a female screw that can be decorated on the upper part, this portion is made of an innocent metal member, which impairs the decoration of the shoelace threader.

  The problem to be solved by the present invention is to provide a shoelace threader that is easy to attach and has high decorativeness.

Shoelace through device according to the present invention was made in order to solve the above-provided string shoe, a shoelace through tool removably attached to the eyelets through the shoelace,
a-1) a flat base portion having an outer dimension larger than the diameter of the eyelet;
a-2) a first member having a protruding portion provided to protrude from the base portion and having an outer dimension smaller than the diameter of the eyelet;
b-1) a head having an outer dimension larger than the diameter of the eyelet;
b-2) a second member having a shoelace through-hole for passing the shoelace provided so as to penetrate the head;
c) provided on either or both of the projection and the head detachably the head portion to portion out projecting at a position where the distance of the head and the base portion is equal to or greater than the thickness of said eyelet And an engaging portion to be engaged.

  In the shoelace threader according to the present invention, the protruding portion of the first member is passed through the eyelet from the inside of the shoe, the second member is brought closer to the first member side from the outside of the shoe, and the protruding portion and the head are connected by the engaging portion. Attach to the shoe by engaging. Since the outer dimensions of the base portion and the head are larger than the diameter of the eyelet, the shoelace threader does not come out of the eyelet after the engagement.

  Since the shoelace threader according to the present invention uses only two parts, the first member and the second member, it is easier to install than the conventional shoelace threader using three parts. is there. Moreover, since it is not necessary to use a washer, the decorativeness is also improved.

  As the engaging portion, for example, a member composed of a male screw formed on the protrusion and a female screw formed on the head can be used. Moreover, the snap-type fastener formed from a protrusion part and a head can be used for an engaging part.

  In the shoelace threading device according to the present invention, a cylindrical portion having an outer dimension smaller than the diameter of the eyelet may be formed on a part of the head portion and the protruding portion can be inserted. In this case, the protrusion is inserted into the cylindrical portion, and the protrusion and the head are engaged with each other with the protrusion passing through the eyelet.

  The shoelace threader according to the present invention may further include a recess on the side surface of the head. By hanging the string on the recess, the shoe can be tightened with the string without passing the string through the shoelace through hole.

  It is desirable that the lower surface of the base portion is subjected to a non-slip treatment. When the lower surface of the base portion is pressed against the eyelet with the belly of the finger or the lower surface of the base portion is pressed against the shoe tongue via the protruding portion with the second member, the first member is engaged with the protruding portion and the head. Can be prevented from undesirably rotating and moving in accordance with the movement of the second member.

  The materials of the first member and the second member are not particularly limited, but metals such as stainless steel and brass can be suitably used in terms of durability, and plastics can be suitably used in terms of cost. Moreover, when using the above-mentioned snap-type fastener for the engaging portion, it is desirable to use plastic as the material of the first member and the second member.

  Decorative tools such as jewels or imitations thereof, or engraved metal members can be attached to the head. Thereby, the decorativeness can be further enhanced.

  Since the shoelace threader according to the present invention does not use a washer, the assembly work is easy and the decorative property is high.

  An embodiment of a shoelace threader according to the present invention will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the shoelace threading device 1 of this embodiment includes a first member 10 and a second member 20. The first member 10 has a base portion 11 and a protruding portion 12, and the second member 20 has a head portion 21, a shoelace through hole 22, and a decorative tool 24.

  The base portion 11 has a disc shape, and the protruding portion 12 is provided at the center of the upper surface of the disc. A male screw is formed on the surface of the protrusion 12. The head portion 21 has a main body portion 211 and a cylindrical portion 212. The main body portion 211 and the cylindrical portion 212 are formed by cutting and thinning one end side of a columnar material, one end side (thinner side) of which is the cylindrical portion 212 and the other end side (thicker side) is the main body portion. 211. The shoelace through hole 22 is a hole penetrating in a direction orthogonal to the cylinder of the main body 211. Further, a recess 23 is provided on the side surface of the main body 211 so as to go around. A female screw is formed in the cylindrical portion 212, and this female screw and the male screw of the protruding portion 12 function as an engaging portion. In the present embodiment, the materials of the base portion 11, the protruding portion 12, and the head portion 21 are all stainless steel.

  The shoelace threader 1 is attached to the outer diameter of the base portion 11 and the outer diameter of the head portion 21 (which corresponds to the larger one of the outer diameter of the main body portion 211 and the outer diameter of the tubular portion 212). It is larger than the diameter of the shoe eyelet 31 (FIGS. 4 and 5). On the other hand, the outer diameters of the protruding portion 12 and the cylindrical portion 212 are smaller than the diameter of the eyelet 31.

  A decorative tool 24 is attached to the upper surface of the head 21 (see FIG. 3A). The ornament 24 is a colored transparent plastic with a pattern imitating a jewel. A “−” (minus) groove 13 is provided on the lower surface of the base portion 11 (FIG. 3B).

  A method of using the shoelace threader 1 of this embodiment will be described with reference to FIGS. 4 and 5. First, the first member 10 is placed between the shoe upper 32 provided with the eyelets 31 in the left and right rows and the tongue 33 (FIG. 5) provided under the eyelet 31, and the eyelet 31 from the lower side of the upper 32. The protrusion 12 is passed through (FIG. 4 (a)). Next, the second member 20 is brought closer to the first member 10 side from the upper side of the upper 32 and the tubular portion 212 is rotated to engage the female screw with the male screw of the protruding portion 12, so that the shoelace threader 1 can be (FIG. 4B). At that time, if the female screw and the male screw are engaged while pushing the lower surface of the base portion 11 directly on the upper side of the finger 32 or via the tongue 33, the groove 13 is prevented from slipping. Therefore, it is possible to prevent the male screw side from rotating in the same direction. The same effect can be obtained by engaging the female screw and the male screw with a coin or the like inserted in the groove 13. The shoelace threader 1 may be attached to all of the eyelets 31 provided in the shoe, or may be attached to only a part thereof.

  Subsequently, the shoelace 34 is passed through the shoelace threading hole 22 of the shoelace threader 1 attached to each eyelet 31 (the eyelet 31 itself when there is an eyelet 31 to which the shoelace threader 1 is not attached) ( 4 (c), (d) and FIG. 5 (b)). The order of passing the shoelaces 34 through the shoelace passage holes 22 is the same as the case of passing the shoelaces 34 through the eyelets 31 as usual. Typically, in order from the toe side, one end of the shoelace 34 is alternately passed through the shoelace threading holes 22 of the shoelace threading device 1 arranged in two rows on the left and right sides, and every other in each row. The other end is passed through the remaining shoelace hole 22. After that, the shoelace 34 is tied after the shoelace 34 is tightened by pulling both ends to the ankle side.

  Next, another usage example of the shoelace threader 1 will be described. In this example, the method of attaching the shoelace threader 1 to the shoe is the same as that in the above example (FIGS. 4A and 4B). The shoelace 34 does not pass through the shoelace passage hole 22, but is hung on the recess 23 from the outside of the row of eyelets 31 (FIG. 6). The order in which the shoelace 34 is hung on the recess 23 of each shoelace threader 1 may be the same as the order in which the shoelace 34 is passed through the shoelace hole 22 in the above-described example. In this way, after the shoelaces 34 are hung on the recesses 23 of all the shoelace threading devices 1, the shoelaces 34 are tied after the shoelaces 34 are tightened by pulling both ends to the ankle side.

  Since the shoelace threading device 1 of the present embodiment is composed of only two parts, the first member 10 and the second member 20, the shoelace threading device 1 is attached to the shoe more than the conventional shoelace threading device composed of three parts. It's easy to do. In addition, since it is not necessary to use an innocent washer, the decoration is high.

  The engaging portion is not limited to a combination of a male screw and a female screw. For example, as shown in FIG. 7, a projecting portion 12A provided on the first member 10A and a cylindrical portion 212A provided on the second member 20A. A set of snap-type fasteners may be configured. Both the base portion 11A and the protruding portion 12A of the first member 10A are made of a flexible material such as plastic. The protruding portion 12A is a column 12A1 provided so as to protrude from the base portion 11A, a vertical groove 12A2 that penetrates in the radial direction of the column 12A1, and is formed from the upper end to the lower end of the column 12A1, and the upper end of the column 12A1. Convex engaging portions 12A3 provided so as to protrude in the radial direction are provided at both ends of the longitudinal groove 12A2. The cylindrical portion 212A has a cylindrical portion that penetrates the inside in the longitudinal direction and has the same distance as the distance between the bottom end of the column 12A1 and the convex engagement portion 12A3. A concave engagement portion 212A2 that is provided at a position away from the lower end of 212A and engages with the convex engagement portion 12A3 is provided. Thus, since the outer diameter of the cylinder 12A1 and the inner diameter of the through hole 212A1 are substantially equal, the diameter of the convex engaging portion 12A3 protruding in the radial direction from the cylinder 12A1 is larger than the inner diameter of the through hole 212A1.

  The second member 20A is fixed to the first member 10A as follows. When trying to insert the protruding portion 12A into the through hole 212A1, the convex engaging portion 12A3 comes into contact with the inner wall of the through hole 212A1 and is pushed toward the longitudinal groove 12A2. At this time, since the cylinder 12A1 has flexibility, the convex engagement part 12A3 moves to the longitudinal groove 12A2 side (the radial direction of the cylinder 12A1), so the convex engagement part 12A3 is inserted into the through hole 212A1. Can do. Then, by further pushing the protrusion 12A, when the convex engaging portion 12A3 reaches the concave engaging portion 212A2, the convex engaging portion 12A3 moves back to the original position and moves outward in the radial direction of the cylinder 12A1. The convex engaging portion 12A3 and the concave engaging portion 212A2 are engaged. Thus, the second member 20A is fixed to the first member 10A. On the other hand, by deforming the base portion 11A, the second member 20A is removed from the first member 10A by pulling out the protruding portion 12A from the through hole 212A1 with the convex engaging portion 12A3 moved to the longitudinal groove 12A2 side. be able to.

  The present invention is not limited to the above embodiments. For example, as the material of the base portion 11, the protruding portion 12, and the head portion 21, other materials such as brass can be used in addition to the above-described stainless steel and plastic. Moreover, it is not essential to provide the cylindrical part 212 in the head part 21, For example, after providing only the main-body part 211, a hole may be directly made in the lower surface side, and an internal thread may be formed. It is not essential to provide the minus-shaped groove 13 on the lower surface of the base portion 11, and a groove having another shape may be provided or the groove may not be provided. Further, a number of irregularities may be provided on the lower surface of the base portion 11 for the purpose of preventing slippage similar to the groove 13.

  The decorative tool 24 is not limited to the pattern shown in FIG. 3A, and the decorative tool 24 may not be provided. The material of the decoration tool 24 is not limited to the above, and opaque plastics and various metals can be used.
