That is, the lower end of the rotary cover 51 is provided with a protrusion 109 is inserted into the rotary pressing groove (53w) to press the wing portion (53y) radially inward as it is rotated in the other circumferential direction. Here, the other direction means that the counterclockwise direction becomes the other direction if the ratchet type gear 57c is formed such that the gear inserted into the ratchet type gear 57c is rotated clockwise.

In addition, it is preferable that the rotational aid 111 having the friction groove 113 formed on the edge of the rotary cover 51 is made of hard synthetic resin. Of course, the present invention is not limited thereto, and the rotary cover 51 and the rotary assistant 111 may be integrally injection molded.

Here, the external force may be generated by rotating the rotary cover 51 clockwise or counterclockwise, or may be generated by pulling the shoelace. Therefore, in the present invention, the shoelace (L) can be tightened or loosened by the action of the external force generated by rotating the rotary cover 51 in consideration of the external force as described above, the shoelace (L) is The external force generated by the pull is composed of a structure that is maintained only tightened but not released.

Figure 3a is a rear view of the shoelace tightening device according to a preferred embodiment of the present invention, Figures 3b and 3c is a rear view of the shoelace tightening device equipped with various forms of elastic means according to a preferred embodiment of the present invention. .

As shown in Figure 3a, the lower portion of the housing 57 is provided with an elastic means 59, the elastic means 59 is provided in the spring fixing portion 151 protruding downward from the housing 57. .

In detail, the elastic means 59 is formed to be provided along an edge of the spring fixing part 151, and both ends of the elastic means 59 are extended portions 59a extending into the spring fixing part 151. Is fixed by being caught by the fixing jaw portion 151a of the spring fixing portion 151.

In addition, the coupling member 121 of the coupling shaft 61 is preferably provided in close contact with the outer circumference of the extension portion (59a) of the elastic means (59). Therefore, when the coupling shaft 61 is pulled upward, the locking jaw portion 123 of the fastening member 121 moves upward while pushing the extension portion 59a from side to side, and the locking jaw portion 123 is moved. When fully passed between the extension portion 59a, the extension portion 59a is returned to its original shape by elastic recovery force and is supported by the lower portion of the locking jaw portion 123 to fix the coupling shaft 61.

In this case, the elastic means 59 may be provided in various forms without being limited to the form formed along the edge of the spring fixing portion 151.

As shown in Figure 3b and Figure 3c, the elastic means may be provided with a spring 157 formed in the "U" shape in consideration of the production convenience, by forming the elastic projection 159a in the leaf spring 159 The lower portion of the housing may be provided using a coupling means such as a bolt.

Here, the function of the spring 157 or the leaf spring 159 of the "U" shape is the same as described above will be omitted.

4a and 4b is a plan view showing the interaction of the rotary cover, the intermediate member and the housing applied to the preferred embodiment of the present invention.

As shown in Figure 4a, the one-way ratchet-shaped gear (57c) is formed in the rotary projection (57b) of the housing 57, the intermediate member 53 and the winding member is stacked in the upper and lower inserts. Then, the rotary cover 51 formed to surround the outer circumference of the rotary protrusion (57b) is disposed on the upper side of the intermediate member 53 is fixed by the coupling shaft (61).

Here, the protrusions (109, 109a) of the rotary cover 51 is preferably coupled to the long pressing groove (53v) formed in a predetermined length and the rotary pressing groove (53w) formed in the wing portion (53y) of the intermediate member (53). Do.

For example, when four protrusions 109 and 109a are formed at the bottom of the rotary cover 51, two protrusions 109 are coupled to the rotary pressing groove 53w, and the other two protrusions 109a are the long grooves. Coupled to 53v. At this time, the ratchet-type gear (57c) is formed in a clockwise direction, it may be formed in a counterclockwise direction according to the convenience of production and use.

As described above, since the four protrusions 109 and 109a are coupled to the rotary pressing groove 53w and the long groove 53v, respectively, when the rotary cover 51 is rotated, the rotational force caused by external force is the protrusion 109. It is delivered to the intermediate member 53 by).

Here, when the rotary cover 51 is rotated in the clockwise direction, the projection 109a coupled to the long groove 53v is caught on one side of the long groove 53v to transmit rotational force to the intermediate member 53. That is, the mating constraining portion 53z of the wing portion 53y is rotated along the teeth of the ratchet-type gear 57c by the rotational force, wherein the wing portion 53y is the intermediate member 53. It is bent to the slack portion 131 of and then returned to its original shape by the action of the elastic recovery force in the next gear. Thus, the intermediate member 53 is rotated smoothly in the clockwise direction by the wing portion 53y repeats this process. However, in the counterclockwise direction, the wing portion 53y is returned to its original shape, and thus the mold clamping portion 53z is not rotated because it is completely engaged with the ratchet gear 57c.

In detail, the external force transmitted to the intermediate member 53 may be divided into an external force transmitted from the rotary cover 51 and an external force transmitted by pulling the shoelace. Therefore, when the mold restraining portion 53z is joined to the ratchet-type gear 57c and the shoelace is pulled, the external force is transmitted to the intermediate member 53. In this case, the external force is applied to the wing portion 53y. Since only the rotational force acts on the mold clamping portion 53z, it is constrained by the ratchet gear 57c and does not rotate counterclockwise.

However, as shown in FIG. 4B, when the rotary cover 51 is rotated counterclockwise, the protrusion 109a coupled to the long groove 53v of the protrusions 109 and 109a of the rotary cover 51 is the long groove. A predetermined distance moves along the 53v, and at the same time, the protrusion 109 coupled to the rotary pressing groove 53w is in close contact with the inner wall portion 145 of the rotary pressing groove 53w to allow the wing portion 53y to be slack. It is pressed to the side 131. At this time, the inner wall portion 145 is formed to extend from the wing portion 53y, it is preferable that the protrusion 109 is inclined to be in close contact with the inner wall portion 145 to generate a predetermined pressing force.

Therefore, the wing portion 53y is bent inward by the pressing force to release the mold fitting restraint 53z from the ratchet gear 57c.

Therefore, due to the external force transmitted by the rotating cover 51, the pressing force for the projection 109a to press the wing portion 53y inward acts on the intermediate member 53 and at the same time rotates in the counterclockwise direction. Because of this action, the intermediate member 53 is rotated counterclockwise.

Thus, since the shoelace tightening device 10 operates as described above, the shoelace tightening device 10 can be tightened or loosened by a simple operation of rotating the rotary cover 51 clockwise or counterclockwise. Ease of use can be improved.

5a and 5b is a side view of the shoelace tightening device showing the interaction of the coupling shaft and the elastic means according to a preferred embodiment of the present invention.

As shown in Figure 5a, the coupling shaft 61 is coupled to one end of the coupling shaft 61, such as bolts in the state passing through the housing 57, the winding member 55, the intermediate member 53 and the rotating cover Means are provided and fixedly coupled.

Here, the coupling hole 171 is formed in the center of the winding member 55, the coupling hole 171 is formed so that the coupling shaft 61 is completely penetrated, as shown in Figure 5a Coupling hole of the winding member 55 so that the edge portion of the coupling hole 173 of the intermediate member 53 stacked on the winding member 55 is caught by the close end 125 of the coupling shaft 61 It is preferable to form smaller than 171.

At this time, from the fastening member 121 of the coupling shaft 61 to the portion 175 in which the close end 125 is formed is formed in a polygon, from the close end 125 to the end of the coupling shaft 61 Portion 177 is preferably formed in a circle. That is, the coupling shaft 61 is formed by forming the coupling hole 179 formed in the housing 57 and the portion 175 up to the close end 125 in a polygonal shape corresponding to each other. Since it is fixed without being rotated, it is possible to prevent loosening of screws due to the rotation.

In addition, the lower portion of the housing 57 is provided with an elastic means 59 in the spring fixing portion 151, the fastening member of the coupling shaft 61 to the both ends extending portion (59a) of the elastic means (59) 121) is installed to take.

In detail, the extension part 59a of the elastic means 59 is formed at a predetermined interval, and the fastening member 121 is disposed between each extension part 59a. In addition, the extension part 59a of the elastic means 59 is mounted on the locking jaw portion 123 formed on the fastening member 121.

Therefore, in a state where the upper part of the locking jaw portion 123 is closely fixed to the extension part 59a, the lower surface of the rotation cover is in close contact with the upper surface of the rotation protrusion part 57b of the housing 57, and the intermediate member 53 is ratcheted. Fully engaged and constrained to the gear. Therefore, when the rotary cover is rotated clockwise or counterclockwise, the shoelace is tightened or loosened by the operation of the intermediate member 53. However, when the tension is generated while the shoelace is tightened, the restraint of the rotating member 53 is not released, so the shoelace is not loosened or loosened. That is, only when the rotary cover is rotated counterclockwise, the intermediate member 53 is rotated counterclockwise so that the shoelace is loosened or released.

On the other hand, when the user loosens the shoelaces to take off the shoe, it is not only inconvenient to rotate the rotary cover every time, but also the lifespan of the shoelace tightening device 10 can be reduced, so the present invention adds a function for improving this.

As shown in FIG. 5B, when the rotary cover is pulled upward, the intermediate member 53 is freed from the ratchet-type gear of the housing 57 to be freely rotatable.

In detail, when the rotary cover is pulled upward, the rotary cover is slid along the outside of the rotary protrusion 57b and protrudes upward at a predetermined length. At this time, the coupling shaft 61 is coupled to the rotary cover by a coupling means. Therefore, the coupling shaft 61 moves upward with the rotation cover. Then, as the fastening member 121 of the coupling shaft 61 moves upward, the locking jaw portion 123 pushes the extension portion 59a of the elastic means 59 to the left and right. Thereafter, the locking jaw portion 123 moves upward to keep the extension portion 59a pushed to the left and to the left, and the extension portion 59a at the lower portion of the locking jaw portion 123 is elastically resilient. Return to form. Then, since the extension portion 59a is supported by the lower portion of the locking jaw portion 123, the coupling shaft 61 may be maintained in a state of moving upward.

At this time, the close end 125 formed on the coupling shaft 61 is caught by the edge of the coupling hole 173 of the intermediate member 53 so that the intermediate member 53 is maintained in a state of moving upward. .

Therefore, since the coupling shaft 61 is fixed in the state moved upward by the elastic means 59 and the locking jaw portion 123, the intermediate member 53 from the ratchet gear of the housing 57 Restraints may be released. Through this, the winding member 55 is rotatable in a clockwise or counterclockwise direction, so that the shoelace is released only if the user pulls the shoelace.

Thereafter, when the rotary cover is returned downward to tighten the shoelace, the intermediate member 53 is again engaged with the ratchet type gear of the housing 57 and restrained. At the same time, as the coupling shaft 61 is moved downward, the locking jaw portion 123 is moved downward by a predetermined length while pushing the extension portion 59a from side to side again and then extended to the upper portion of the locking jaw portion 123. The part 59a is supported. Therefore, the intermediate member 53 is laminated to the upper portion of the take-up member 55 and is constrained by the ratchet-type gear.

As such, the shoelace tightening device 10 may not only tighten or loosen the shoelace with a simple operation of rotating the rotary cover in one direction or the other direction, that is, clockwise or counterclockwise, but also completely tightens the shoelace. In order to loosen, the user only needs to pull the rotary cover upwards, so that the operation is easy and the convenience of use can be improved.

In addition, the shoelace tightening device 10 is a simple that can release the intermediate member 53 from the ratchet-type gear of the housing 57 according to the vertical movement of the coupling shaft 61 or the left and right rotation of the rotary cover. Because of the structure, the number of components is not only easy to assemble, but also to reduce the production cost, thereby improving economics and productivity.

Furthermore, since the shoelace tightening device 10 can tighten or loosen the shoelace conveniently and stably due to a simple operation, it can be used to attach to sneakers and various shoes as well as significantly increasing the quality and reliability of the product. By attaching the shoelace tightening device can be differentiated from other products to secure the market competitiveness of the product.

Meanwhile, the shoelace tightening device according to the present invention is not limited to being used only for tightening shoelaces, and may be applied to a plurality of devices for tightening shoelaces and other devices to which the technical spirit of the present invention is applied. Application of the will also belong to the scope of the present invention.

As described above, the present invention is not limited to the above-described embodiments, but may be modified and implemented by those skilled in the art without departing from the scope of the claims of the present invention. Such modifications are within the scope of the present invention.
