Description

Shoelace fastener {apparatus for fastening shoe strip}

The present invention relates to a shoelace tightening device, and more particularly to a shoelace tightening device that is significantly improved ease of use and productivity.

In general, shoes such as sneakers are provided so that the shoelaces are connected in a zigzag form so as to be in close contact with the size of the foot of the user, by pulling and tightening the shoelaces to increase the adhesion of the shoes and the user's feet to enable comfortable walking.

Of course, shoes should be chosen to be of an appropriate size so that they do not come off while walking, and it is common to wear shoes with the shoelaces slightly loosened so that they are suitable to be taken off and put on. Tightening the shoelaces to fit snugly is known to be good for the health of the feet.

However, it is very cumbersome to loosen or tighten the shoelaces every time you wear them, so except for special cases, it is not uncommon to wear shoes while keeping them properly tied, but during normal walking, the shoelaces will loosen and walk. It may cause the hassle to stop and re-tie the shoelaces, and even if it is not released, both ends of the shoelaces may not be fixed, which may give a sense of neatness, even if the shoelaces are long.

Moreover, in the case of young children and the elderly who are in elementary school lower grades or before elementary school, the shoelaces are not easy to tighten, and in particular, for athletes or people who are exercising, such as mountain climbing and racing, Loosening of shoelaces should be absolutely prevented because unfavorable results such as record degradation and safety accidents are caused by violent movements or knots caused by violent movement or by external objects.

In addition, during breaks during exercise, the tightly-tied shoelaces must be easy to relax, and most preferably, the shoelaces can be easily tightened. Must be present

In order to facilitate the fastening and loosening of the shoelaces in conflict with each other as described above, a number of devices for easily tightening the shoelaces have been developed, and the Korean Utility Model Registration No. 598627 filed by the present applicant uses ratchet gears. Although shoelace tightening machine is disclosed, this shoelace tightening machine is inconvenient to use because it is necessary to loosen the shoelace by holding the stopper by pushing it to one side after winding the shoelace by rotating the rotating member. There was a difficult problem to use.

In addition, when the shoelace tightening machine fails to properly push the stopper to one side when the shoelace is loosened, the unwinding process is troublesome and troublesome, which lowers the reliability of the product. When the stopper fixture is disposed, there is a problem in that the product structure is significantly reduced due to a complicated structure and a large number of parts.

The present invention is to solve the above problems to provide a shoelace tightening device to improve the ease of use and productivity.

In order to solve the above problems, the present invention is a housing formed with a circular space inside; Rotating member is rotatably coupled to the housing, the ratchet gear is formed on the inner circumference, the return groove is formed on the upper outer circumferential edge, the rotating member is provided with a bobbin to selectively wind the shoelace in the lower portion; An intermediate member having a rotation shaft penetrating the rotating member from its central portion and having an end coupled to the housing; And a fixing protrusion having an asymmetrical inclined surface which is elastically supported by the intermediate member and is restrained by an external force to be constrained by the external force and restrained by the upper outer circumferential edge of the rotating member to return to the return groove in the winding direction. When the projection is returned, the lower part is partially engaged with the ratchet gear to restrain rotation in the direction in which the shoelace is released, but the stopper is provided with a stopper which is released from the ratchet gear when the fixing protrusion is constrained to the upper outer rim of the rotating member. It provides a shoelace tightening device comprising a cover for.

The intermediate member may include a cylindrical protective part having an outer circumferential surface that is not restrained by the ratchet gear and having an elastic support means interposed therebetween, and the stopper released from the ratchet gear is accommodated inside the cylindrical protective part.

The shoelace tightening device according to the present invention provides the following effects through the above solution.

First, when the shoelaces are wound by rotating the rotating member, when the shoelaces are released again, when the fixing cover is pushed in one direction, the fixing protrusion is fixed by being bound to the edge of the rotating member so that the shoelace does not need to be continuously pushed by the stopper by hand. Since it can be solved, the ease of use can be significantly increased. In addition, when it is necessary to tighten the shoelaces in this state, the convenience of the tightening operation can be remarkably increased because the fixing protrusion returns to its original position simply by turning the rotary member in the tightening direction without the need for a separate operation. .

Second, it is possible to tighten or loosen the shoelaces conveniently and stably through simple operation, which can significantly increase the quality and reliability of the product.

In the state of FIG. 4C, as described above with reference to FIGS. 3A and 3B, a stopper (132 in FIG. 2) formed on the lower surface of the fixing cover 130 is formed on the inner side of the rotating member 120 ( Partially joined to 122 of FIG. 2, the rotational member 120 can be rotated clockwise while the shoelace L is tightened, but the rotation in the counterclockwise direction in which the shoelace L is released is restricted. Therefore, when the rotary member 120 is continuously wound clockwise, the shoelace is effectively tightened, and due to the ratchet gear (122 in FIG. 2) bound by the stopper (132 in FIG. 2), the shoelace is not loosened and joined. State can be maintained.

Of course, as shown in FIGS. 3A to 3C, the inclinations of both edges of the return groove 125 may be different from each other, thereby inducing a smoother operation. That is, the edge of the return groove 125 facing the gentle inclined surface 135a of the fixing protrusion 135 has a gentle inclined surface, and the return groove 125 facing the sudden inclined surface 135b of the fixing protrusion 135. The edge of is preferably formed to have a steep slope.

In addition, it will be appreciated that the depth of the return groove 125 is deeper toward the top, thereby inducing a smoother operation to be easily empirically modified by those skilled in the art.

As described above, the present invention, when the shoelace (L) is wound by rotating the rotating member 120 through the interaction between the fixing protrusion 135 and the return groove 125 provided simply, Pushing the fixing cover 130 in one direction, the fixing protrusion 135 is constrained and fixed to the rim of the rotating member 120, so that the ratchet gear 122 can be easily released from the stopper 132, and shoes again If it is necessary to tighten the string (L) only need to rotate in the direction of tightening the rotating member 120 without the need for a separate operation, because the fixing projection 135 is returned to its original position, the convenience of tightening again will be significantly increased. Can be.

Through this, it is possible to significantly increase the quality and reliability of the product.
