Binding for Snowboard {Binding For Snowboard}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding for snowboard, and more particularly, to a binding for snowboard which can easily mount and detach a binding and can easily control the binding force of the binding.

Snowboarding is a type of winter sports that you enjoy on your snow, slipping down the diarrhea while moving your weight center with your feet on one deck. Snowboarding requires the installation of a binding that selectively secures or unlocks the user's boot to the deck.

The strap-type binding according to the prior art has a problem of cumbersome and inconvenient that it requires not only repeatedly performing a sitting up and standing posture for attaching and detaching but also a process of fastening and loosening a plurality of straps. Particularly, in snowboarding, a thick coat and gloves are worn, so that there are restrictions on the activity, and the attachment and detachment of the binding becomes more complicated and inconvenient.

Conventionally, Korean Patent Registration No. 10-1438174 discloses a binding for snowboards.

1 is a side view of a binding for a snowboard of Korean Patent No. 10-1438174.

As shown in FIG. 1, Korean Patent No. 10-1438174 discloses a binding for a snowboard comprising a side wall 16 fixed to a base, a guide extending from the side wall, a movable side wall A high bag 56 hingedly connected to the movable side wall at one end thereof, a lever 64 hinged to the rear side of the high bag, a first wire 72 and a second wire 72, which form a closed circuit and pass through the inside of the member, A wire 74 and a third wire 86, a fourth wire 90 for causing the lever to come into close contact with the rear surface of the high back, and a displacement adjusting portion located inside the side wall.

Korean Patent No. 10-1438174 discloses a binding for a snowboard in which the first wire 72 and the second wire 74 and the third wire 86 are bonded together by bringing the lever 64 into close contact with the high bag 56, It is possible to generate a tensile force on the surface of the metal plate and conveniently mount the binding. The first wire 72 and the second wire 74 and the third wire 86 can be released by releasing the lever 64 from the high bag 56 at the time of detachment. And the strength of the tensile force generated on the wire can be controlled through the displacement adjusting part provided on the side wall 16. [

However, Korean Patent No. 10-1438174 has a merit that the binding for snowboarding can be easily carried out by simply operating the lever 64, but the strength of the tensile force generated on the wire can be controlled It is inconvenient to do so, and there is also a disadvantage in that the adjustment of the tensile force is small. The displacement control unit is not a structure that can be adjusted immediately from the outside, and it is difficult to control the tensile force of the wire in a wide range because the displacement width is small.

Conventionally, Korean Patent Laid-Open No. 10-2007-0025943 discloses binding for snowboards.

2 is a side view of a binding for a snowboard of Korean Patent Laid-Open Publication No. 10-2007-0025943.

2, the binding for snowboards of Korean Patent Laid-Open No. 10-2007-0025943 includes a base plate 102 on which the boot B is seated, A strap 110 made of a contact member 112 and a fixing member 114 and a fixing means 116 and a covering member 118 and a wire W; (120).

Korean Patent Application Publication No. 10-2007-0025943 discloses a binding for a snowboard in which a tensile force is generated on a wire W by a winding device installed inside when the fastening means 120 is turned, (102) are brought into close contact with each other to fix the boots (B).

However, in the case of the binding for snowboards of Korean Patent Laid-Open Publication No. 10-2007-0025943, since the pulling force is generated on the wire by turning the tightening means 120, the binding can be easily mounted and detached, 120, the strength of the tensile force can be controlled by the number of turns and the turning strength. However, the boots are not structured so as to surround the boot, but the tensile force is generated only at the foot of the boots. 120 are projected to the outside of the binding, there is a drawback in that aesthetics and usability are deteriorated.
