Boardsport Foot-binding Mounting Plate

Abstract

The invention is an accessory boardsport foot-binding mounting plate. The invention provides a means for the rapid adjustment of foot-binding mounting angles without the use of tools. The invention is comprised of two concentric discs, which, in isolation from each other, have no moving parts. The invention is to be mounted between a foot-binding and a board. When mounted, the upper disc can be manually rotated over the lower disc, clockwise and counterclockwise, to effect a rotational lock and unlock of the foot-binding. When unlocked, the foot-binding drops approximately 1/10 th of an inch, disengages from its retaining plate, and can be freely rotated to any desired angle in 360 degrees on the plane of the board. The foot-binding angle can be changed with or without the users foot actively strapped into the foot-binding.

1 . A sportsboard foot-binding mounting plate, comprising:
 two concentrically stacked discs, a lower disc and an upper disc, wherein the stacked discs are mounted between a sportsboard and a foot-binding.   
     
     
         2 . The sportsboard foot-binding mounting plate as in  claim 1 , wherein the mating surfaces of said upper and lower discs have semicongruent radial surface features of various thicknesses which serve to alter the height of the disc stack as the rotational alignment of said upper and lower discs is altered, thereby raising or lowering the foot-binding chassis relative to its retaining plate. 
     
     
         3 . The sportsboard foot-binding mounting plate as in  claim 1 , wherein said stacked discs are through-bolted between a sportsboard and a foot-binding.
