ABSTRACT:
This invention relates to a rider responsive boot binder attachment mechanism that enhances the maneuverability and responsiveness of a snowboard to rider movements. A pair of first plate members 15 are secured in spaced relationship to a snowboard, a pair of second plate members 20 are rotatably secured, one each, to the first pair of plate members and boot binder mechanism 14 attached to each of the second plate members at the desired angulation therewith. Elastomeric structure in the form of elongated spiral springs 24,26,28 and 30 are disposed between each connected first and second plate to limit relative rotation therebetween and to exert a force on the plates to effect return to an original preset position after the plates have been rotated relative to each other by rider applied torque action. Adjustment mechanism is provided in each boss and stop element disposed at each end of each spring to adjust the effective length of each spring and thereby regulate the initial compression or tension exerted by each spring. A ball bearing assembly facilitates relative rotation between plates 15 and 20.
