Snowboard binding

Abstract

The present invention relates to a snowboard binding. The snowboard binding comprises: a base, a high back, a foot cover, a first wire, and a lever. The base comprises a plate attached to the snowboard, and side walls extending vertically from both sides of the plate. The high back is installed to pivot on the side wall in the rear of the base. The foot cover is installed at a distance from the upper front of the base. The first wire connects the high back to the base and foot cover. The lever is installed to pivot on the back of the high back and moves the foot cover as the length of the first wire connecting the lever to the high back varies depending on the pivot direction, wherein the first wire connected to the high back is connected to the side facing the pivot axis. Therefore, the foot cover and high back simultaneously fix the front and rear of boots as a result of the pivoting of the lever in the locking direction, and release of the lever is prevented.

1 . A snowboard binding comprising:
 a base which forms a plate attached to a snowboard and a side wall extending vertically from both sides of the plate;   a high back which is rotatably installed in the side wall in the rear of the base;   a foot cover which is installed at a distance from the upper front of the base;   a first wire which connects the high back to the base and foot cover; and   a lever which is installed to pivot on the back of the high back and moves the foot cover as the length of the first wire connecting the lever to the high back varies depending on the pivot direction, wherein the first wire connected to the high back is connected to the side facing the pivot axis.   
     
     
         2 . The snowboard binding according to  claim 1 , wherein the first wire has a spring inserted thereinto to provide an elastic force in a direction spacing the foot cover from the base in an area exposed between the base and the foot cover and high back. 
     
     
         3 . The snowboard binding according to  claim 2 , wherein the first wire has a tube inserted thereinto to shorten an elastic distance of the spring. 
     
     
         4 . The snowboard binding according to  claim 3 , wherein the first wire provides tension in a direction maintaining a pivot location of the lever while the lever pivots in a pulling direction. 
     
     
         5 . The snowboard binding according to  claim 1 , wherein the base forms a path in a front end of the side wall to be penetrated by the first wire. 
     
     
         6 . The snowboard binding according to  claim 5 , wherein the high back forms connection paths on both sides of a center thereof to be penetrated by the first wire. 
     
     
         7 . The snowboard binding according to  claim 6 , wherein the foot cover forms a first path penetrated by the first wire connecting the foot cover and paths on both side walls of the base, a second path penetrated by the first wire connecting the path in a lateral side of the base and the connection path of the foot cover and high back, and a third path penetrated by the first wire connecting the path in the side wall of the base and the connection path of the foot cover and high back. 
     
     
         8 . The snowboard binding according to  claim 7 , wherein the lever comprises a length adjusting means to adjust a length of the first wire. 
     
     
         9 . The snowboard binding according to  claim 8 , wherein the length adjusting means comprises a rotating member forming a female screw therein and rotatably installed in the lever, and a male screw formed in an end part of the first wire and coupled to the female screw of the rotating member, which are provided in both ends of the first wire. 
     
     
         10 . The snowboard binding according to  claim 9 , wherein the length adjusting means further comprises a moving body which has the rotating member rotatably installed in both sides, forming a first uneven part shaped like a saw tooth in a side facing the lever and forming an opening vertically in a center thereof; a second uneven part engaged with the first uneven part of the moving part on a surface on which the moving body is installed; and a coupling member penetrating the opening of the moving body and coupled to the lever. 
     
     
         11 . The snowboard binding according to  claim 10 , wherein the length adjusting means further comprises a second wire which connects the base to the high back and lever and prevents the high back from moving backward while the lever pivots in a pulling direction.
