Angle adjuster for snowboard binder

Abstract

The present invention relates to an angle adjuster for a snowboard binder; the angle adjuster for a snowboard binder according to the present invention comprises a fixation member that forms a first locking part on its plate face and has first projection pieces protruding at least from both sides of its upper edge to be fixed on the snowboard, a base that has a through hole formed on its center, whereinto the fixation member is inserted, a diaphragm that is respectively formed on both sides of the base in a vertical direction, first combination grooves that are formed in a vertical direction at least on both sides of the through hole so that the first projection pieces may be inserted thereinto, a binder that is assembled with the fixation member to enable its rotation along upper grooves whereby the first projection pieces move along the upper edge of the through hole of the base, and a coupling member assembled above said binder whereon is formed a second locking part that mates with the first locking part of the fixation member at its bottom.

1 . An angle adjuster for a snowboard binder comprising:
 a fixation member which forms a first locking part on a plate face thereof and has first projection pieces protruding from at least both sides of an upper edge and fixed to a snowboard;   a binder which comprises a base forms a through hole on a center thereof to insert the fixation member thereinto, a diaphragm that is formed in a vertical direction in both sides of the base, first combination grooves that are formed in a vertical direction in at least both sides of the through hole to insert the first projection pieces of the fixation member thereinto, and upper grooves that are formed along an upper edge of the through hole of the base to move the first projection pieces of the fixation member, and is rotatably assembled to the fixation member; and   a coupling member which forms a second locking part on a lower surface thereof to mate with the first locking part of the fixation member and is assembled to an upper side of the binder.   
     
     
         2 . The angle adjuster for a snowboard binder according to  claim 1 , wherein the second locking part forms a plurality of concave and convex parts on an external surface thereof which protrudes from a lower center of the coupling member, and the first locking part is depressed from the center of the fixation member to insert the second locking part thereinto and forms concave and convex parts in an internal surface thereof to mate with the concave and convex parts of the second locking part. 
     
     
         3 . The angle adjuster for a snowboard binder according to  claim 2 , wherein the second locking part is shaped like a cone with its upper part cut and has a diameter of an front end that is smaller than a diameter of a rear end, and the first locking part is shaped corresponding to the second locking part so that the second locking part is inserted into and mates with the first locking part. 
     
     
         4 . The angle adjuster for a snowboard binder according to  claim 1 , wherein the binder forms second projection pieces from lower sides of the through hole in a location cross the first combination grooves, and the fixation member forms second combination grooves in a vertical direction in an external side thereof to insert the second projection pieces of the binder thereinto and forms lower grooves along a lower edge to move the second projection pieces. 
     
     
         5 . The angle adjuster for a snowboard binder according to  claim 1 , further comprising a locking member which prevents the coupling member from being separated from the fixation member by fixing the coupling member to the fixation member with the first locking part and the second locking part mating with each other. 
     
     
         6 . The angle adjuster for a snowboard binder according to  claim 5 , wherein the locking member comprises a locking piece which is rotatably installed in an upper side of a guiding groove formed in the diaphragm of the binder and presses the upper surface of the projection of the coupling member to closely adhere the projection to the base. 
     
     
         7 . The angle adjuster for a snowboard binder according to  claim 6 , wherein the binder forms the guiding groove in a vertical direction in an internal surface of the diaphragm, and the coupling member forms a projection in both sides thereof to insert the projection into the guiding groove. 
     
     
         8 . The angle adjuster for a snowboard binder according to  claim 7 , wherein the binder forms an extension groove in an upper side of the guiding groove to communicate with the guiding groove in a horizontal direction. 
     
     
         9 . The angle adjuster for a snowboard binder according to  claim 8 , wherein the coupling member forms a folding handle on an upper surface thereof. 
     
     
         10 . (canceled) 
     
     
         11 . The angle adjuster for a snowboard binder according to  claim 5 , wherein the locking member forms coupling projections on lower sides thereof and comprises a rotating shaft which is rotatably installed in the coupling member, an insertion opening which is shaped like a rectangle and is formed in a plate face of the fixation member to insert the coupling projection of the rotating shaft thereinto, and a space which is formed in an internal area of the insertion opening to rate the coupling projection of the rotating shaft while being inserted into the insertion opening. 
     
     
         12 . The angle adjuster for a snowboard binder according to  claim 11 , wherein the rotating shaft forms a folding handle on an upper surface thereof.
