The through hole 2b of the left slide member 4 is formed so as to penetrate the left slide member 4 in the front-back direction, and has a smaller dimension in the sliding movement direction than the left through hole 2a of the case 3 The dimension in the direction orthogonal to the slide movement direction is slightly increased.

The right slide member 5 is accommodated in the case 3 so as to be slidable in the left-right direction x, and includes a through hole 2c of the right extending portion Ra that constitutes the through portion 2.

In the illustrated example, the right slide member 5 is formed by forming the through hole 2c in a substantially rectangular plate-shaped body. The right slide member 5 has a dimension in the slide movement direction smaller than the distance from the middle position in the length direction of the case 3 to the right end 3e, and has a dimension in the direction orthogonal to the slide movement direction. Of the inner surface of the pair of side portions 3c on the thickness side, and its thickness is substantially equal to the distance between the inner surfaces of the front and back side portions 3a, 3b of the case 3. ing. The through hole 2c of the right slide member 5 is formed so as to pass through the right slide member 5 in the front-back direction, and has a smaller dimension in the sliding movement direction than the right through hole 2a of the case 3 while The dimension in the direction orthogonal to the slide movement direction is slightly increased.

The link member 6 is between the left slide member 4 and the right slide member 5, a part of the left slide member 4 projects from the left end 3d of the case 3, and the right end 3e of the case 3 extends to the right side. The left-side slide member 4 and the right-side slide member 5 are linked so that a part of the slide member 5 projects, and the structure is elastically deformable.

In the illustrated example, the left-side slide member 4, the right-side slide member 5, and the link member 6 form a movable part 7 as an integrated synthetic resin molded product.

In the illustrated example, the linking member 6 integrates the band left end 6b with the left side slide member 4 and the band right end 6c with the right side slide member 5, and also between the band left end 6b and the band right end 6c. Shows a belt-like shape bent at two places. Specifically, the linking member 6 includes a bent portion 6a located on one side and a bent portion 6a located on the other side with the cylindrical axis y (see FIG. 2) of the case 3 interposed therebetween. The linking member 6 is configured to have a meandering shape around the cylinder axis y. Further, the linking member 6 has a band shape having a width substantially equal to the distance between the inner surfaces of the front and back side portions 3a, 3b of the case 3, and the width direction of the band is along the thickness direction of the case 3. Thus, it is formed between the left side slide member 4 and the right side slide member 5. Further, the left end 6b of the linking member 6 is a part of the left slide member 4 which is located inside the case 3 and is integrated with a corner portion on one side sandwiching the cylinder axis y. Further, the right end 6c of the linking member 6 is a portion located in the case 3 of the right slide member 5 and is integrated with a corner portion on the other side sandwiching the cylinder axis y. With the linking member 6 configured in this way, with respect to the case 3, with the left slide member 4 partially protruding from the left end 3d of the case 3 and the right slide member 5 partially protruding from the right end 3e of the case 3. The movable parts 7 are combined together.

In addition, in this embodiment, one of the left-side slide member 4 and the right-side slide member 5, the right-side slide member 5 in the illustrated example, and the slip-out stopper that is caught in the through hole 2a of the case 3 are prevented. The part 5a is formed. In the illustrated example, a protrusion-like retaining portion 5a that protrudes in a direction orthogonal to the plate surface of the right slide member 5 is provided on the front surface and the back surface of the right slide member 5 at the connecting portion between the right slide member 5 and the right end 6c of the link member 6. Each is formed. The distance between the protruding ends of the front and back retaining portions 5a is slightly larger than the distance between the inner surfaces of the front and back side portions 3a and 3b of the case 3. In the illustrated example, when the movable part 7 is inserted into the case 3 to combine them, the retaining portion 5a is allowed to enter the case 3 mainly by elastic deformation of the case 3, and the retaining portion 5a serves as the case. By the elastic return of the case 3 side at the insertion position into the through hole 2a on the right side of 3, the combined state of both is maintained.

In this embodiment, the left slide member is elastically deformed by utilizing a part of the left slide member 4 and a part of the right slide member 5 protruding from the case 3. By narrowing the distance between 4 and the right slide member 5, the left and right extending portions Ra can be inserted into the left and right through portions 2, respectively.

By holding a part of the left slide member 4 protruding from the case 3 and a part of the right slide member 5 protruding from the case 3 into the case 3 at the same time by holding the knot substitute member 1 with one hand, the case 3 The communication range between the through hole 2a on the left side and the through hole 2b of the left slide member 4 and the communication range between the through hole 2a on the right side of the case 3 and the through hole 2c of the right slide member 5 are enlarged to replace the knot. The left and right extending portions Ra can be respectively inserted into the left and right through portions 2 of the member 1 with low resistance.

As shown in FIG. 3, in this embodiment, the rear side of the case 3 is passed between the left slide member 4 and the left bent portion 6a of the linking member 6 through the through hole 2a on the left side of the case 3. Then, the left side extension member Ra pulled out to the front side of the case 3 is pushed in by the left side slide member 4 as described above, so that the case 3 is again passed through the through hole 2b of the left side slide member 4 and the left side through hole of the case 3. The knot substitute member 1 can be fastened to the left extended portion Ra by pulling it out to the back side of. The left extending portion Ra is held between the left slide member 4 and the case 3 by the urging force of the linking member 6 while being wound around the right side portion 4a of the left slide member 4.

In addition, a right side extension part which is passed from the back side of the case 3 through the right side through hole 2a of the case 3 between the right side slide member 5 and the right bent part 6a of the linking member 6 and is drawn out to the front side of the case 3 By pushing Ra into the right side slide member 5 as described above, the Ra is pulled out to the back side of the case 3 again through the through hole 2c of the right side slide member 5 and the right side through hole 2a of the case 3 to reach the right extending portion Ra. The knot substitute member 1 can be fastened. The right extending portion Ra is clamped between the right slide member 5 and the case 3 by the urging force of the linking member 6 while being wound around the left side portion 5b of the right slide member 5.

When tightening the shoelace R, the extra length portion Rb extending from the knot substituting member 1 in the left and right extending portions Ra is pulled. That is, when the extra length portion Rb is pulled in the direction indicated by the symbol f1 in FIGS. 3 and 4, the left slide member 4 and the right slide member 5 move slightly in a direction in which the distance between the left slide member 4 and the right slide member 5 is narrowed while elastically deforming the linkage member 6. As a result, the fastening force with respect to the extending portion Ra is reduced.

When loosening the shoelace R, the left slide member 4 and the right slide member 5 are pushed together and the knot replacement member 1 is held, and the knot replacement member 1 is pulled away from the shoe. That is, the knot substitute member 1 is moved in the direction indicated by the symbol f2 in FIG.

Further, in the first example shown in FIGS. 1 to 14, the knot substitute member 1 is a state in which the string gathering member 9 is passed through the extra length portions Rb of the left and right extending portions Ra together. In, a fitting portion 8 to be fitted into the string gathering member 9 is provided.

In the illustrated example, the fitting portion 8 is a shaft-like body that extends from the middle position in the length direction of the case 3 toward the toe Sb side of the shoe S. In the illustrated example, the fitting portion 8 has one end integrated with the outer surface of the thickness side portion 3c of the pair of thickness side portions 3c of the case 3 which is located on the toe Sb side of the shoe S. Then, the case 3 projects from the middle position in the lengthwise direction in a direction orthogonal to the cylinder axis y of the case 3. The left side surface 8b of the fitting portion 8 and the right side surface 8c of the fitting portion 8 intersect at a tip 8f of the fitting portion 8 so as to form an acute angle. The left side surface 8b of the fitting portion 8 and the right side surface 8c of the fitting portion 8 are formed by an inclined portion 8d that gradually increases the lateral dimension of the fitting portion 8 as it moves away from the tip 8f of the fitting portion 8, and the end of this inclined portion 8d. And an engaging projection 8a is formed on the tip end side of the shaft-like body to be the fitting portion 8.

On the other hand, the string bundling member 9 allows the excess length portion Rb extending from the knot substituting member 1 in the left and right extension portions Ra to pass together, and is fastened at an arbitrary position with respect to the passed excess length portion Rb. It is configured to turn on.

In this embodiment, the cord bundling member 9 is a sleeve-shaped member made of an elastically deformable material. Such a sleeve-like body is typically made of plastic (plastic elastomer) having rubber-like elasticity.

In the illustrated example, the string bundling member 9 has a rectangular tubular shape with both ends of the tube open. A raised portion 9a is formed at a position in the middle of the string binding member 9 in the cylinder axis direction. In the illustrated example, the raised portions 9a are formed on the left and right inner wall portions of the string bundling member 9, respectively. The raised portion 9a has a rib shape extending between inner wall portions on the front and back sides (upper and lower sides in FIG. 12) of the string bundling member 9. A narrowed portion is formed inside the string binding member 9 by the left and right raised portions 9a. Further, in the illustrated example, a recess 9b is formed at a position in the middle of the front and back direction of the raised portion 9a, and the distance between the left and right raised parts 9a is slightly wider at the position in the middle of the front and back direction. Between the left and right raised portions 9a, the left and right extending portions Ra of the shoelace R cannot pass at the same time unless the lace binding member 9 is elastically deformed. That is, the string binding member 9 is adapted to allow the left and right extending portions Ra of the shoelace R to pass therethrough by elastic deformation.

By passing the left and right extending portions Ra of the shoelace R through the through portions 2 of the knot substitute member 1, the shoelace R can be maintained in a tightened state without forming a knot in the shoelace R. By passing the extra length portions Rb of the left and right extending portions Ra together through the string gathering member 9, the string gathering member 9 is fastened to the extra length portion Rb, and the left and right extending portions are passed through the string gathering member 9. Ra can be summarized. From this state, the fitting portion 8 of the knot substitute member 1 is fitted into the string gathering member 9 while the string gathering member 9 is elastically deformed from the introduction side of the extending portion Ra of the string gathering member 9 to fit the knot. The alternative member 1 and the cord bundling member 9 can be integrated. This fitting can be smoothly performed by the inclined portion 8d on the tip 8f side of the fitting portion 8. Since the engaging protrusion 8a is formed on the fitting portion 8 of the knot substitute member 1 and the raised portion 9a is formed on the string binding member 9, the engaging protrusion 8a rides over the raised portion 9a. By inserting the fitting portion 8 into the string tying member 9 to the position, the knot alternative member 1 and the string tying member 9 can be stably integrated. As shown in FIG. 4, an intermediate portion Rc of the left and right extending portions Ra, which is located between the knot substituting member 1 and the string tying member 9, integrates the knot substituting member 1 and the string tying member 9. It becomes a loop in the converted state. This makes it possible to create an appearance similar to that when the shoelace R is bow-knotted. Further, the shoelace R can be tightened by pulling the intermediate portions Rc of the left and right extending portions Ra which are looped in this way, and when the shoelace R is tightened, the portion to be pulled can be clearly recognized. it can.

FIGS. 15 to 19 show the second part of the shoelace fastener in which the engaging portion 10 for the engaged portion 11 provided in the knot substitute member 1 is formed on the outer side of the lace binding member 9. An example is shown. In this second example, the case 3 that constitutes the knot substitute member 1 is provided with an engaged portion 11 instead of the fitting portion 8 of the first example. Since the remaining structure of the knot substitute member 1 in this second example is substantially the same as that of the first example, the same components are the same as the reference numerals used in FIGS. 1 to 14 showing the first example. 15 to 19 and the description thereof will be omitted. In addition, since the configuration of the cord tying member 9 in the second example other than the engaging portion 10 is substantially the same as that of the first example, the same components are illustrated in FIGS. 1 to 14 showing the first example. The same reference numerals as those used are given to FIGS. 15 to 19 and their explanations are omitted.

In this second example as well, the left and right extending portions Ra of the shoelace R are passed through the through portions 2 of the knot substitute member 1 so that the shoelace R is tightened without forming a knot. Can be maintained. By passing the extra length portions Rb of the left and right extending portions Ra together through the string gathering member 9, the string gathering member 9 is fastened to the extra length portion Rb, and the left and right extending portions are passed through the string gathering member 9. Ra can be summarized. From this state, by engaging the engaging portion 10 of the knot substituting member 1 with the engaged portion 11 of the knot substituting member 1, the knot substituting member 1 and the string tying member 9 can be integrated. it can.

In this embodiment, the engagement portion 10 has a shaft shape protruding from the string gathering member 9 in a direction intersecting with the passing direction z (see FIG. 15) of the extra length portion Rb of the string gathering member 9. It is the body 10a. More specifically, the shaft-shaped body 10a has one end integrally connected to the outer wall on the back side of the string gathering member 9 and projects from the outer wall in a direction orthogonal to the cylinder axis of the string gathering member 9. In the illustrated example, the shaft-shaped body 10a is configured to have a substantially circular cross-sectional shape at any position in the protruding direction. A head portion 10b is formed at the other end of the shaft-shaped body 10a, and a neck portion 10c is formed between the head portion 10b and one end of the shaft-shaped body 10a. The head portion 10b has an orbiting jaw portion 10d as a step between the head portion 10b and the neck portion 10c, and the apex on the side opposite to the orbiting jaw portion 10d is a truncated cone portion 10e, and the neck portion 10c and the truncated cone portion 10e. The maximum diameter portion 10f that maximizes the outer diameter is defined between and.

On the other hand, in this embodiment, the engaged portion 11 is a through hole 11b formed in the tongue portion 11a protruding from the knot substitute member 1 toward the toe Sb side of the shoe S. .. In the illustrated example, the tongue piece portion 11a has a plate shape including an upper side portion 11c, a lower side portion 11d, and left and right side portions 11e, and the upper side portion 11c has a pair of thickness side portions of the case 3. 3c is integrated with the outer surface of the side portion 3c on the side of the thickness of the shoe S located on the side of the toe Sb of the shoe S, and is orthogonal to the tubular axis y of the case 3 from the middle position in the longitudinal direction of the case 3. It is sticking out. The thickness of the tongue portion 11a is equal to the thickness of the side portion 3c on the thickness side of the case 3. In the illustrated example, the through hole 11b is a circular hole that penetrates the tongue piece portion 11a in the front and back. The inner diameter of the through hole 11b is substantially equal to the diameter of the neck portion 10c of the shaft-shaped body 10a, and is slightly smaller than the diameter of the maximum diameter portion 10f of the head portion 10b.

In the second example, when the shaft-shaped body 10a is pushed into the through hole 11b from the front side of the case 3, the elasticity of the tongue portion 11a side and/or the shaft-shaped body 10a side of the case 3 is reduced. By the deformation, the shaft-shaped body 10a can be inserted into the through hole 11b. The slanted peripheral surface of the truncated cone portion 10e facilitates the insertion. In this fully inserted state, the jaw of the head 10b is caught on the hole edge of the through hole 11b on the back side of the case 3, whereby the knot substituting member 1 and the string tying member 9 are on the front side of the knot substituting member 1. In the above, the cord binding members 9 are integrated in a state of being projected (FIG. 19).
