Abstract
A lock mechanism for releasably securing an anti-crossing device for skis to the upper surface of a ski so that the member which is affixed to the ski does not have any dangerous projections thereon once the anti-crossing device has been removed from the ski. The anti-crossing device cooperates with a fastening plate secured to the ski, which fastening plate has slots therein into which are received pins mounted on the anti-crossing device. A locking pin is reciprocally movable on the anti-crossing device and is received into an opening in the fastening plate and is resiliently held in position to maintain the pins in engagement with the slots.
Claims13
In combination, an attachment member for a ski and a device for fastening said attachment member to a ski, said combination comprising:
- a fastening plate and first fastening means for fastening said fastening plate to said ski, said fastening plate having at least one raised portion thereon with an upper wall, encircling sidewall means and a cavity therebeneath;
- first means defining an elongate insert slot in said raised portion and communicating with said cavity, the longitudinal axis of said elongate slot extending transversely of the longitudinal axis of said ski, said insert slot having an elongated first segment located in said upper wall of uniform width and a sidewardly opening second segment in said sidewall means of a width greater than said uniform width, both of said first and second segments of said insert slot communicating with said cavity;
- second means defining a first opening in said fastening plate adjacent to said raised portion;
- an elastic plate positioned between said attachment member and said fastening plate;
- at least one coupling pin mounted on said attachment member and having a diameter less than said uniform width of said first segment, said coupling pin having an enlarged end on one end thereof of a width greater than said uniform width of said first segment and less than the width of said second segment, said enlarged head being received in said cavity through said second segment when said attachment member is superposed on said elastic plate;
- a locking member and mounting means for mounting said locking member to said attachment member, said mounting means including means defining a second opening in said attachment member coaxial with said first opening in said fastening plate when said attachment member is superposed on said elastic plate, said locking member being slidably disposed in said second opening and movable between a first position retracted from said first opening and a second position received in said second opening, said locking member when in said second position preventing a movement of said attachment laterally of said longitudinal axis of said ski and a removal of said enlarged head from said cavity through said second segment to thereby effect a locking of said attachment member to said fastening plate;
- resilient means connected to said locking member and said attachment member for continually urging said locking member into said second position;
- and
- manually engageable means connected to said locking member for facilitating a movement of said locking member to said first position against the urging of said resilient means to permit a movement of said enlarged head laterally of said longitudinal axis of said ski through said second segment to permit a release of said attachment member from engagement with said fastening plate.
