Patent ID: 8191917

Claim:
A snowboard binding, comprising: a mount, being comprised of a bottom plate and two lateral flanges protruding vertically at both sides of said bottom plate, said bottom plate having a snowboard locating portion set centrally thereon, a front opening formed in a front thereof, and a rear opening formed behind said bottom plate; a rear plate extending vertically and having a bottom pivoted onto a rear side of said two lateral flanges of the mount; two top plate assembly bases, mounted correspondingly at a front of said two lateral flanges of the mount, each top plate assembly base having a top plate joint and a trigger support joint assembled transversely at intervals on the top plate assembly base, said top plate joint being located higher than the trigger support joint; a rotary top pressboard, being comprised of a snowboard boot press surface and two mating frames extending from both frontal sides of the snowboard boot press surface, the two mating frames being separately pivoted onto the top plate joint of two top plate assembly bases, the snowboard boot press surface of the rotary top pressboard being able to swing backwards into a pressing state, or forwards into an open state by taking the top plate joint as a pivot; a trigger support, having a curved shape defining a trigger section and two mating ends at both ends of the trigger section, the two mating ends being separately pivoted onto the trigger support joint of the two top plate assembly bases, the trigger section swinging forwards or backwards by taking the trigger support joint as a pivot; and two coupling plates, coupled between the mating frames of the rotary top pressboard and the mating ends of the trigger support, each coupling plate being comprised of a first coupling end and a second coupling end, the first coupling end being pivoted onto the rotary top pressboard close to the mating frame, the second coupling end being pivoted onto the trigger support close to the mating end, each coupling plate, the mating frames of the rotary top pressboard, the mating ends of the trigger support and the top plate assembly base being coupled together to form a four-bar mechanism, wherein a swinging angle of the snowboard boot press surface of the rotary top pressboard exceeds 90° forming a super-wide-angle guide port of the snowboard boot, allowing to directly slip the snowboard boot downwards for loading purpose.
