Description

[0001] Apparatus for fastening wire [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire tightening device, and more particularly, to a wire tightening device with improved assemblability and durability.

In general, shoes such as athletic shoes are provided so that the shoelace is connected in a zigzag fashion so as to be in close contact with the user's foot size. By tightening the shoelace by pulling it, the adhesion between the shoe and the user's foot is enhanced to enable comfortable walking.

However, in the case of young children or elderly people who are in the lower grades of elementary school or elementary school, loosening their shoelaces is not easy, and in the case of athletes or people who are exercising such as mountain climbing or bicycle race, If the knot is loosened by an intense movement or by an external object, the loosening of the shoelace should be absolutely prevented, since undesirable results such as recording degradation and occurrence of safety accidents are caused.

In addition, when resting during a workout, the shoelace fastened tightly can be easily restrained, so that it is most preferable to easily tighten the shoelace, to stably maintain the tightened state, and to easily loosen the shoelace if necessary .

Accordingly, many devices have been developed to facilitate tightening and loosening of shoelaces which are contradictory to each other.

1 is a perspective view of a shoe with a conventional shoelace tightening device, and Fig. 2 is an exploded perspective view of a conventional shoe strap fastening device.

1 and 2, a conventional shoelace tightening device 10 is provided on a sulphone T of a shoe. When the rotary cover 51 is rotated, the intermediate member 53 and the winding member 55 Combined and rotated together. At this time, the shoe strap (L) is wound around the winding member and the binding restraining portion (53z) of the intermediate member is restrained by the unidirectional ratchet gear (57c) of the housing (57) without being rotated in the reverse direction.

When the rotary cover 51 is then pulled upward, the engaging jaw 62 of the rotary shaft 61 elastically pressurizes the elastic means 59 to be opened while being moved upward, so that the intermediate member 53 is raised. As a result, the state of engagement between the intermediate member 53 and the winding member 55 is released and the winding member 55 rotates freely, so that the shoe strap L is pulled and loosened.

For this, there has been a problem that the elastic means 59 formed as a thin metal "U" shape is separately manufactured and assembled into the shoelace tightening device 10 through a complicated assembling process.

In addition, when the shoe strap fastening period 10 pulls the rotary cover 51 upward when the shoelace is pulled back, the shoe strap fastening period 10 causes a failure of the product when the elastic means 59 is released from the original position. In order to solve this problem, the structure of the lower structure of the housing 57 to which the elastic means 59 is coupled is complicated and the number of components is increased and the product productivity is lowered.

Further, since the rotation cover 51 and the rotary shaft 61 are fastened to each other by the bolt member, an operation error occurs when the bolt member is not completely fastened, and the rotation shaft 61, which is a resin injection product, There is a problem that it is easily broken by a metal bolt member.

That is, since malfunctions such as lifting the lifting unit 140 due to vibration or shock due to exercise or the like can be prevented without direct manipulation by the user, it is possible to prevent a safety accident caused by unexpected wire loosening and the like, Can be improved.

At this time, when the lifting unit 140 and the cover unit 150 are lifted by an external force, the upper slope of the slide protrusion 142a is slid along the lower slope of the upper slope 134, Radially outward elastic deformation.

When the slide protrusion 142a passes through the tongue 134, the slide protrusion 142a is radially inwardly supported by the elastic restoring force of the elastic piece 142, Lt; / RTI >

Accordingly, the lifting unit 140 is lifted to separate the lifting protrusion 152 and the reel unit 120, and the reel unit 120 can be freely rotated. That is, if the lifting unit 140 is pulled once, the state where the wire can be pulled and pulled out is maintained without any other operation, so that the usability of the product can be improved.

At this time, the maximum elevation height of the lifting unit 140 and the cover unit 150 is limited by the interval between the hook projections 141a of the lifting unit 140 and the engaging jaws of the housing unit 130 .

When the release of the wire is completed, the elevator unit 140 and the cover unit 150 can be downwardly pressed so that the elevation protrusion unit 152 and the reel unit 120 can be easily switched.
