Description

  The present invention comprises a closure for securing and tightening a shoelace of a shoe, comprising a case forming a chamber for receiving an end portion of the shoelace, wherein the shoelace passes through at least one opening and the chamber. A cover is provided which is insertable into the chamber and closes the chamber, wherein the cover has an open position where the shoelace can be manipulated and a closed position where the chamber is closed by the end of the shoelace therein. The closure is movable between.

  The shoelace closure is used for tightening a shoelace and fixing its position in a shoelace-type shoe. The shoelace closure eliminates the need to make knots and loops to secure the shoelace. Shoelace closures are preferred, for example, in the case of sports shoes worn on a daily basis and are becoming increasingly popular. Closures that tighten both ends of a shoelace are known. For example, Patent Document 1 describes a shoelace closure in which a shoelace is held by a clamp mechanism. In this case, the shoelace end portion normally protrudes from the clamp mechanism, but there is a safety risk because the shoelace end portion may trip and fall over, for example. Since the shoelace is dimensioned so that both ends thereof can be tied together, when the end portion is fastened and fixed, the end portion hangs down very long. For this reason, in the said patent document 1, it has proposed cutting a shoelace edge part into a desired dimension. However, this fixes the maximum width of the shoe that can use the shoelace. Furthermore, the cut shoelace cannot be used with a suitable shoelace closure because its length is not sufficient for a normal knot with a loop.

  Furthermore, Patent Document 2 describes a closure in which a wedge-shaped insert presses a shoelace against a stop surface to prevent pulling out. Patent Document 3 discloses a closure in which a shoelace is inserted into a groove of the closure and is held by being pressed by a cover in the groove. From Patent Document 4, a closure clamp is known in which a tied shoelace is tightened and fixed by a clamp. In patent document 5, a shoelace is hold | maintained at a holding | maintenance part by the clamp surface which can be rotated. In Patent Document 6, the shoelace is fixed by a fastening wedge that is held displaceably. Patent Document 7 describes a closure for fixing a normal loop. According to Patent Document 8, a closable cover for a string and a loop is provided, and Patent Document 9 describes a closable case for receiving a normal loop. Finally, Patent Document 10 describes a closure that is fixed to a shoelace region to be inserted and that has a shoelace end inserted into a hook shape. The hook is movable with a rotatable case member for tightening and packing, in which case the shoelace end is wrapped around a rope drum inside the closure. This closure is not easy to remove from the shoe, and it takes some time and effort to initially install and set it on the shoe.

  It is an object of the present invention to provide a shoelace closure that avoids sagging and sagging of the shoelace end and can be attached very easily.

  This object is achieved according to the invention in a shoelace closure of the kind described at the outset, provided with a clamping mechanism for the shoelace, which holds the tightened shoelace, and each clamping mechanism has one clamping mechanism in the chamber. Formed by a gap, which tapers toward one end, so that the shoelace can be tightened in the taper area, the gaps face each other by the taper area, and the gaps are respectively inward from the case The problem is solved by being formed by the strip portion protruding to the bottom and the case bottom.

  The advantage of the shoelace closure according to the invention is that both shoelace ends can be quickly and reliably packed into the case. In so doing, it is possible to pack the entire length of the protruding part, ie the part necessary for the knot, usually with a loop. Since the end portion of the shoelace does not hang down from the shoe, the other shoe does not hit against one end of the shoelace that is slacking. Furthermore, inadvertent unwinding of the shoelace ends is prevented. By the case and the cover, the shoelace closure can be configured as a compact member. Therefore, the shoelace closure according to the present invention is particularly suitable for a modern supose shoe, which has a high design value and is intended to correspond to the material used with a modern and innovative shape. Since the clamp mechanism is disposed in the case, it is not necessary to fix the clamp mechanism to the shoe so that the shoelace end can be tightened. Rather, the shoelace ends are not fixed to the shoe, but are fixed to each other using a case as in the case of the loop. On the other hand, unlike the loose clamp mechanism, which must be held and operated by the user, the clamp mechanism according to the present invention is held by a case abutting the shoe for easy operation. ing. The shoelace closure according to the present invention does not require any special treatment or mechanism in the shoe, so that it can be used in various shoes, for example, or can be quickly replaced with other shoes. It is also suitable for additional equipment for shoes. There is no need for a special work for fixing the shoelace, particularly a work for penetrating the shoelace portion inserted into the shoe. In addition, the cover protects the shoelace end from fraying. The clamping mechanism is also protected from contamination or damage by its moving parts.

  According to the invention, the clamping mechanisms for the shoelaces are each formed by one gap, which tapers towards one end, so that the shoelace can be tightened in the tapered region. Both the gaps may be formed in the case in various ways, and the structure can be changed very easily even when the case is manufactured from a plastic member. The shoelace is first inserted into the chamber through the opening, where the shoelace can be suitably manipulated through the open cover. In this case, the shoelaces can be easily tensed, and are inserted into the respective gaps and tightened in a tensed state.

  According to the invention, the gaps are opposed to each other by their tapered regions. As a result, the clamping force can be suitably absorbed by the case, and no force is generated in the rotational direction.

  Furthermore, according to this invention, the clearance gap is formed of the strip part and case bottom part which protrude inward from the case, respectively. In this case, both strips have a hook-like shape, and the bottom of the case may be open or closed below the strips. When the case bottom is open, the shoelace can be suitably clamped and fixed between the sharp edge of one opening and the sharp edge of the strip. Each of the edges is configured on the one hand to generate a large tightening force, and on the other hand it is configured to be too sharp to damage the shoelace.

In the objective configuration of the present invention, the cover is pivotally fixed to the case, and as a result, the user does not need to hold the cover separately when operating the clamp mechanism.
Furthermore, an embodiment is advantageous in which the case is shaped concavely on its lower surface so that it can be suitably attached to the curved upper surface of the shoe in the instep region. In this case, it is preferable that the case has bending elasticity so that it can be adapted to the shape of the mounting portion. As a result, the closure is prevented from pushing the foot in the form of dots, so that a more comfortable comfort can be obtained.

Preferably, it is the two openings for their respective one shoelace ends is disposed on the lower surface of the case. In this case, a space-saving embodiment is obtained. Since the opening is formed on the lower surface of the case, the closure is installed on the shoe where the ends of both shoelaces protrude from the eyelets, so the shoelace ends are completely covered after the eyelets. It extends in a shoelace closure.

  Particularly suitable is an embodiment in which the opening for inserting the shoelace end into the chamber is between the gaps. In such an embodiment, the shoelaces can be suitably tightened, for example, simply by pulling them apart from each other, and can be fixed so as not to slip.

  Wrap the loose end of the shoelace around the strip so that it can be packed as user-friendly as possible, i.e., quickly and easily. It is possible to attach. For this reason, the gap is formed somewhat longer and larger in the expanded region than is necessary for the original fastening.

In another advantageous embodiment, a protrusion is formed on the case, and a shoelace end can be fixed behind the protrusion. This prevents the shoelace end from obstructing the closing of the cover.
In an advantageous embodiment, the cover is provided with a case closure that allows the cover to be opened and closed with respect to the case .

With the closure that allows the cover to be opened and closed with respect to the case , the case can be reliably closed during transportation. The closure, for example, a normal lock mechanism, or, magic click tape (trade name), has a zipper, magnetic lock, a snap button fastener.

FIGS. 1 to 14 show a closure 310 for tightening and fixing a shoelace of a shoe as another embodiment.
The closure 310 has a case 312 for accommodating the end of a shoelace. In order to attach the case 312 to the instep region of the shoe, the lower surface thereof is formed in a concave shape, and has bending elasticity that can be adapted to the shape of the attachment site.

The vertically long case 312 has a bottom plate 314, and a cover 316 for closing the chamber is rotatably held by the bottom plate 314. In order to temporarily fix the cover 316 in the closed state, a case closure 318 is provided between the cover 316 and the case 312 so that the cover 316 can be opened and closed with respect to the case 312. A cover 316 is movably held by a bottom plate 314 (see also FIGS. 5 and 6). The case closure 318 includes a lock mechanism that is released by pressing a button 319.

  The case 312 has two openings 320 and 322 on the lower surface, and a shoelace is inserted into the chamber through the openings. A clamp device 324 is provided on the bottom plate 314 inside the chamber, and a shoelace is fixed using the clamp device 324. In this case, the clamp device 324 is held stationary with respect to the case 312. The clamp device 324 has gaps 326 and 328 that are open on one side for each shoelace, and the gaps 326 and 328 move from the insertion opening to the gap to fasten and fix the shoelace. Tapered. The gaps 326 and 328 are respectively formed between the strips 330 and 332 projecting from the case 312 into the chamber and the edge of the withdrawal portion provided at the bottom of the case. In this case, both openings 320 and 322 are arranged between gaps aligned with each other (illustrated so as to be separated from each other). The strips 330 and 332 are, for example, T-shaped in cross section, and the tapered gaps 326 and 328 are generated by deformed side surfaces that are spaced outward from the case bottom.

The strips 330, 332 are selected with respect to their lengths so that the slack region of the shoelace can be wrapped around the strips 330, 332 in the outer region of the gaps 326, 328. . The case closure 318 has a projection 334 so that the shoelace end can be moved to the rear of the projection 334 so that the shoelace end can be packed more suitably. When the cover 316 is closed, it does not protrude sideways.

  Only the decorative clip 336 is provided on the upper surface of the cover 316, and a company logo, an advertisement, or the like can be attached on the decorative clip 336 in addition to the decorative element. The decorative clip 336 is fitted on the cover 316 and held by the cover 316 by a small locking protrusion (see also FIGS. 11 to 13).

  In FIGS. 14a-14h, the use of the shoelace closure 310 according to FIGS. 1-13 is illustrated in the context of a supose shoe. Of course, the shoelace closure 310 can be used for other types of shoes. First, the shoelace closure 310 is opened by pressing the push button 319. Next, the shoelace is inserted from below through the holes 320 and 322 provided on the lower surface of the case 312. In the illustrated embodiment, the holes 320 and 322 are not arranged between the strips 330 and 332 but are located behind the strips 330 and 332 on the side of the opening for inserting the gap. Is arranged. Next, the shoelace closure 310 is positioned in the center of the shoe, so that the holes 320 and 322 are located above the shoe, where the shoelace protrudes from the eyelet of the shoe. Next, the shoelace is tightened as necessary. For this purpose, the shoelace is first pulled outward and crossed with a cross at a slight angle and at a small angle to the shoe. At this time, the shoelace is tightened in the gaps 326 and 328 behind the strips 330 and 332 (see step a in FIG. 14c). In this case, the tightening action is first effected by the tapered gap 326 or 328, but supplementarily also by a shoelace crossing the cross.

  As an alternative to the tapered gaps 326, 328, a gap having a uniform width may be used. The tightening action in this case is achieved only with shoelaces that are crossed multiple times. In this case, however, the tension of the shoelace must be maintained longer when it is wound around the strip.

  In order to obtain the desired strength, i.e. to hold the shoe with the desired holding force with the foot, according to Fig. 14c the protruding strips 330, protruding from bottom to top, respectively, with a small circular motion, Wrap around 332. For this reason, the shoelace is then tightened by pulling the shoelace upward (see step b in FIG. 14d).

  Thereafter, as shown in FIG. 14e, the remaining free regions of the shoelaces, ie, the loose regions, are alternately wrapped around the free ends of the strips 330,332. In order to prevent the shoelace end from sticking between the bottom plate 314 and the cover 316 when the cover 316 is closed, the shoelace end is lightly pushed and slid under the case closure 318 formed as a protrusion. . For this purpose, shoelace ends are particularly suitable where the shoelace end comprises a plastic sleeve or a metal sleeve (FIG. 14f). Finally, close the cover. In this case, the cover 316 is securely held by locking the closure mechanism. To open, the closure button 319 is pressed to open the cover 316. In this case, the pivotable coupling can be easily opened by being prestressed in a closed state. When the cover is closed, the decorative clip is well visible on the top surface of the shoelace closure 310 and can be used, for example, to attach a company logo or other advertising elements (see FIG. 14h).
