5 is a side view of the tightening state of the shoelace tightening device of the present invention, Figure 6 is a front view of the tightening state of the shoelace tightening device of the present invention, Figure 7 to Figure 9 of the present invention Fig. 10 is a front view of the tightening state of the shoelace tightening device of the present invention.

First, as shown in FIG. 5, the tightening means 140 is installed on the front surface of the tongue 120 disposed inside the opening 111 of the shoe body 110, and the lever 150 of the tightening means 140 is provided. In the state in which the rotation in the tightening direction is released, both sides of the opening 111 of the shoe body 110 is opened, the tongue 120 protrudes outward from the opening 111 of the shoe body 110, the shoe body ( It becomes a state which is easy to put a foot into the inside of 110).

That is, as shown in FIG. 6, the shoelace 130 has a second end 141a of the guide 141 and the movable body 142 in a state where one end thereof is supported by the through hole 112 formed at one lower end of the opening 111. After passing through the first through hole (142a) of the opposite side through the through hole 112, and exits to the adjacent through hole 112 communicated through the tube 113, the second through hole (141a) of the guide 141 again And both sides of the opening 111 are connected in a substantially zigzag form while being repeatedly inserted through the first through hole 142a of the moving body 142 and inserted into the through hole 112 on the opposite side, and then The other end inserted into the through hole 112 provided at the upper end is exposed to the upper side of the shoe body 110.

A spherical shoelace handle 132 is fixed to the distal end of the shoelace 130 exposed to the outside through the upper end hole 112 of the shoe body 110 to facilitate pulling the shoelace 130.

At this time, since the shoelaces have little frictional force acting on the movement of the shoelace in the state of being inserted into the tube connecting the through holes provided at both sides of the opening, so that the length of the shoelace connecting the openings can be easily adjusted. do.

In addition, between the shoelace handle 132 and the upper end hole 112 of the opening 111 is connected by the length adjusting means 131 provided to the lower end one-side hole 112 and the upper end hole 112 is adjusted. It is possible to fix the length of the shoelace 130 adjusted to the size of the user.

That is, the adjusting body 131a of the length adjusting means 131 is fixed to the outside of the shoelace 130 by holding the outside of the shoelace 130, the cap screwed to one end of the control body 131a According to the rotation direction of the (131b) it is possible to adjust the length of the shoelace 130 while being fixed or released of the shoelace 130 selectively. Accordingly, the shoe wearer can set the width of the opening 111 in the state of being released in accordance with their feet or adjust the degree of tightening by the shoelace 130 in the state of tightening.

In addition, when opening both sides of the opening 111 in a state in which the length adjusting means 131 is released to increase the length of the shoelace 130 connecting between the opening 111, the shoelace 130 is an opening (111) Since the friction force with the shoelace 130 is hardly generated by being inserted into the tube 113 provided in the through hole 112 on both sides, the length of the shoelace 130 for easily connecting the openings 111 is increased. It becomes possible.

On the other hand, the movable body 142 located between the guides 141 on both sides of the fastening means 140 fixed to the tongue 120, the lever 150 is rotated in the tightening direction as shown in the drawing of the opening 111 It is located on the lower side.

In this state, the shoelaces 130 connecting the second through holes 141a of the both side guides 141 and the first through holes 142a of the movable body 142 are kept in a parallel state, thereby guiding the guide 141. Shoelace 130 located between the second through hole (141a) and the through hole 112 formed on both sides of the opening 111 of the shoe body 110 is to maintain a loose state, so the opening 111 of the shoe body 110 ) The sides will be opened with easy footing.

Looking at the state in which the lever 150 of the tightening means 140 in the tightening direction in the released state as described above are as follows.

7 is a front sectional view showing a state in which the lever 150 of the tightening means 140 is rotated in the tightening direction, as shown in the drawing, the guide 141 is fixed to the front surface of the tongue 120, and the guide 141 is fixed. In the state in which the cover 143 is fixed to the front surface of the cover 143, the moving body 142 is positioned in the lower space between the guides 141 inside the cover 143.

In addition, the fixing plate 151 of the lever 150 is fixed to the outside of the upper end of the cover 143, one end of the handle 152 is rotatably installed on the fixing plate 151, the center of the cover 143 The movable body 142 exposed through the provided opening hole 143a is connected to the handle 152 by the connecting member 153.

Here, the handle 152 is a sliding member 152d surrounding the outer side of the rotating member 152a which is rotatably fixed to the fixing plate 151 while sliding along the longitudinal direction of the rotating member 152a and the handle 152. The overall length of the elongated, the insertion shaft 152e provided inside the sliding member 152d in the long hole 152c formed in the longitudinal direction in the rotating member 152a is inserted to guide the movement of the sliding member 152d At the same time, the separation of the sliding member 152d is prevented.

In particular, in the state in which the rotating member 152a is rotated in the unlocking direction, that is, in the inclined downward direction, as shown in the drawing, the sliding member 152d surrounding the outer side of the rotating member 152a slides downward by gravity. While moving in the outward direction from the center of rotation of the rotating member (152a), thereby increasing the overall length of the handle 152 it is possible to rotate the handle 152 by a small force by the principle of the lever.

On the other hand, the connecting member 153 is the first fixing part 153a is installed to the handle 152 rotatably and the second fixing part 153b is exposed through the opening hole 143a of the cover 143. The first fixing part 153a and the second fixing part 153b are connected by the connecting ring 153c in a state of being fixed to the front surface of the movable body 142.

8 is a cross-sectional view showing a state in which the lever 150 of the tightening means 140 rotates in the tightening direction. As shown in the drawing, when the handle 152 rotatably installed on the fixing plate 151 rotates in the tightening direction, the connection is performed. The movable body 142 connected to the handle 152 by the member 153 is moved upward by the movement of the cover 143 in the space between the guides 141.

At this time, when the rotation member 152a of the handle 152 contacts the locking step 152b of the stopper 154 installed on the fixing plate 151, the stopper 154 elastically moves downward, and then the rotation member ( When the 152a is completely rotated, the handle 152 moves to the original position again by the elastic force of the elastic member (not shown) and is caught by the locking jaw 152b to restrain the rotational position of the rotation member 152a. Is arbitrarily prevented from being untightened while being rotated in the tightening direction.

In addition, the sliding member 152d surrounding the outer side of the rotating member 152a is disposed to be inclined upwardly in a state in which the handle 152 is rotated in an unlocked state as shown in the drawing. At this time, the sliding member 152d is reduced in the downward direction from the outside of the rotation member 152a by gravity automatically reduces the overall length of the handle 152, so that the front part of the wearer's ankle or shin is not caught in the front part.

On the other hand, the second fixing part 153b of the connecting member 153 is fixed to the moving body 142 by the fastening member S penetrating the second fixing part 153b, and is rotated according to the rotation of the handle 152. The movable body 142 is moved, and the movable body 142 is provided with a plurality of fastening holes 142b to which the fastening member S penetrating the second fixing part 153b is spaced at a predetermined interval in the longitudinal direction. .

Therefore, the tightening degree of the shoelace 130 is adjusted with respect to the movement of the movable body 142 according to the fixing position of the second fixing part 153b fixed to the movable body 142, thereby adjusting the overall length of the shoelace 130. You can finely adjust the tightening degree according to the user's foot size without having to.

9 is a front sectional view showing the position of the movable body in a state in which the lever of the tightening means 140 is rotated in the tightening direction as described above, and guides disposed on both sides of the front surface of the tongue 120 as shown in the drawing by the rotation of the lever. The moving body 142 moves upward between 141.

At this time, the moving body 142 is moved upward from the state in which the shoelace 130 is connected in a substantially horizontal state between the second through hole 141a of both side guides 141 and the first through hole 142a of the moving body 142. As the shoe lace 130 is pulled upward in the space between the guides 141 on both sides, the gap between the second through hole 141a of the guide 141 and the first through hole 142a of the movable body 142 increases. The distance between the second through hole 141a of the guide 141 and the through hole 112 on both sides of the opening 111 of the shoe body 110 is narrowed in proportion to the distance, so that both sides of the opening 111 are tightened.

In particular, the shoelace 130 is a central portion of the shoelace 130 in a state in which both sides of the through-hole 112 alternately repeated in a zigzag form from the lower end portion of the opening 111 of the shoe body 110 to the upper end side alternately several times. Since the connected movable body 142 is moved, the shoelaces 130 can be tightened at a time, and the force to pull both sides of the opening 111 acts evenly from the lower end to the upper end of the opening 111. Done.

In addition, the guide 141 is disposed adjacent to both sides of the moving body 142 to pull the shoelaces 130 from both sides with respect to the movement of the moving body 142, a plurality of along the longitudinal direction of the opening 111 Since the tightening force of the shoelace 130 is acted at a location, it becomes possible to design a short moving distance of the moving body 142.

On the other hand, the action of the tightening release with respect to the action in the tightening direction as described above proceeds in the reverse order with respect to the action in the tightening direction, if moving the stopper 154 in the unlocking direction, as shown in the enlarged view of FIG. The stopper 154 is separated from the locking step 152b of the rotation member 152a so that the handle 152 of the lever 150 can be rotated in the tightening direction, and the shoelace 130 is tightened. Since the pulled state of the stopper 154 is moved in the tightening direction as described above, the handle 152 is automatically rotated in the tightening direction by the pulling force of the shoelace 130.

Particularly, in the case of releasing the shoes, the shoelaces 130 are uniformly released by the movement of the movable body 142 from the upper end to the lower end of the opening 111 of the shoe body 110, so that the shoe body 110 may be loosened. It is very easy to take the foot out of it.

Next, a shoelace tightening device according to a second embodiment of the present invention will be described.

In addition, in the upper region of the movable body 142 ', the first guide 145a is disposed adjacent to both sides of the movable body 142' branched in the shape of “Y”, and is formed in the region between the movable body 142 'which is branched. As the movable body 142 'moves upward in the state where the two guides 145c are disposed, the first through hole 142a of the movable body 142' and the second through hole 145b and the first guide 145a of the movable body 142 'are formed. Since the distance between the third through hole (145d) of the two guides (145c) is pulled out so that the shoelace 130 is pulled, both sides of the upper portion of the opening 111 of the shoe body 110 is tightened toward the center.

Here, as described above, the branched upper region of the movable body 142 'is divided into two movable bodies 142' compared to the lower region, so that each branched movable body 142 'is divided into a first guide 145a and a second guide. Since the shoelaces 130 are respectively pulled out between the 145c, the shoelaces 130 are pulled twice as much as the lower region of the movable body 142 '.

Therefore, it is possible to increase the tightening force in shoes with long ankles, such as boots or boots, and to secure excellent tightening force instead of shortening the moving distance of the moving object 142 'in shoes having short or no ankles, such as hiking boots or sneakers. It provides an advantage.

Meanwhile, in the above-described embodiments, one shoelace has been described as connecting the both sides of the opening in a zigzag form, but connecting the side of the moving body through the adjacent guides from both sides of the opening through the two shoelaces, It may be possible to connect a plurality of times in the zigzag form at both sides along the opening direction of the opening.

The scope of the present invention is not limited to the above-described embodiment, but may be embodied in various forms of embodiments within the scope of the appended claims. Without departing from the gist of the invention claimed in the claims, it is intended that any person skilled in the art to which the present invention pertains falls within the scope of the claims described in the present invention to various extents which can be modified.

The present invention has the advantage of performing the action of tightening or releasing through a single operation.

In addition, since the shoelaces are evenly released from the top to the bottom of the opening when unfastening, it provides an advantage that the shoes can be easily taken off.

In addition, since the shoelaces are respectively pulled from both sides of the moving body, not only an excellent tightening force can be secured, but also a short moving distance of the moving body can be designed.

In addition, it is possible to prevent the release of the handle of the lever in the state of being rotated in the tightening direction.

In addition, when the handle is rotated in the tightening direction, the handle can be rotated in a state in which the length of the handle is extended, thereby making it possible to operate the handle of the lever with a small force by the lever effect.

In addition, the length of the handle is automatically extended in the state in which the handle is rotated in the tightening direction, and the length of the handle is automatically contracted in the state in which the handle is rotated in the tightening direction.
