ABSTRACT:
A boot to ski attachment mechanism which provides three degrees of attachment. When the heel is against the ski a threaded detent provides a greatly adjustable retention against vertical separation with full restraint against lateral separation. When the heel is raised out of the detent to an intermediate elevation, only lateral restraint is provided. When the heel is above the intermediate elevation, the heel is free of lateral restraint to allow twisting as during a fall. These three degrees of attachment are provided by upstanding legs on opposite sides of the heel, along with detent mechanism having parts on the upstanding legs and heel. The detent action between the upstanding legs and heel is made infinitely adjustable by a threaded rod and nut arrangement with said nut being carried by either the heel structure or upstanding leg structure while the transverse pin is carried by the other of the heel or upstanding leg structures. Relative rotation of the pin and nut varies the force necessary required for vertical separation between the heel and upstanding legs.
