Abstract
The plate release binding for winter sports devices comprises a mobile binding plate (1) of oblong basic outline with a widened mid-section and a vertical central bore (28). The entire engagement and disengagement mechanism, mainly comprising pressure springs (12) and pressure pistons (13) is built into the compact plate into a minimum of space below the area of the boot sole. The binding plate is engaged with the fixed mounted hub (2) on the snowboard by a downward and turning movement of the foot. The hub acts as the only anchoring device for each binding and at the same time also as the central rotational, pivotal and guiding axis for the multi-directionally turning , tilting and lifting movements of the plate.
Claims9
A plate release system for a pair of bindings that releasably secures the boots of a snowboard rider to a snowboard and for automatically releasing the boots from the snowboard upon a predetermined force being exceeded on said boots, each one of said pair of bindings comprising:
- a base plate adapted to be fixedly mounted to the upper surface of the snowboard,
- a hub adapted to overlie said base plate,
- an anchor bolt extending through the center of said base plate and said hub, each of said base plate and said hub having radially extending teeth which are adapted to overly in mating relationship to define a plurality of angular positions of rotation of said hub about a vertical axis of said base plate, said anchor bolt being adapted to lock said hub to said base plate in a selected one of said angular positions,
- a rotatable plate adapted to be attached to the sole of the boot, said plate having a central vertical bore for rotatably receiving said hub, and
- connection means for releasably coupling said plate to said hub, said connection means including at least one spring-biased pressure piston located in said plate, said piston having a tip portion extending into said central bore and recesses located along a radial periphery of said hub for selectively receiving said piston, whereby said connection means releases said plate from said hub in response to said predetermined force.
