Ski brake

Claim 1

A device for braking of a ski upon release of a ski boot from a binding comprising: a sole plate mounted on said ski and adapted to normally remain therewith, said sole plate having at least one binding thereon for releasably holding said ski boot to said sole plate; a pair of separate and identically formed substantially rigid brake members, each of said brake members having an L-shape with one leg of the L defining a braking mandrel and the other leg defining a pivot shaft, said pair of pivot shafts extending generally horizontally and transversely to the longitudinal axis of said ski; bearing means on said sole plate for supporting said pivot shafts for both an axial movement and a rotatable movement; a bifurcated spring wire tensioning lever having a pair of resilient legs fixedly connected to said pivot shafts, and being pivotal therewith between a first upright position transverse to the longitudinal axis of said ski and a second position generally parallel to the longitudinal axis of said ski, said legs being flexible from a normal relaxed position inwardly toward each other and a tensioned position; cam means on said sole plate engaging said legs of said tensioning lever while in said tensioned position for continually urging said tensioning lever from said second position toward said first position whereat said legs are in said relaxed position; and means defining a cavity in the upper surface of said sole plate wholly receiving said tensioning lever therein when in the tensioned position thereof whereby said ski boot rests directly on said sole plate.

Claim 2

A device for braking of a ski upon release of a ski boot from a binding comprising: a sole plate mounted on said ski and adapted to normally remain therewith, said sole plate having at least one binding thereon for releasably holding said ski boot to said sole plate; a pair of separate and identically formed substantially rigid brake members, each of said brake members having an L-shape with one leg of the L defining a braking mandrel and the other leg defining a pivot shaft, said pair of pivot shafts extending generally horizontally and transversely to the longitudinal axis of said ski; bearing means on said sole plate for supporting said pivot shafts for both an axial movement and a rotatable movement; a bifurcated spring wire tensioning lever having a pair of resilient legs fixedly connected to said pivot shafts, and being pivotal therewith between a first upright position transverse to the longitudinal axis of said ski and a second position generally parallel to the longitudinal axis of said ski, said legs being flexible from a normal relaxed position inwardly toward each other and a tensioned position; cam means on said sole plate engaging said legs of said tensioning lever while in said tensioned position for continually urging said tensioning lever from said second position toward said first position whereat said legs are in said relaxed position; and means defining a cavity in the upper surface of said sole plate wholly receiving said tensioning lever therein when in the tensioned position thereof whereby said ski boot rests directly on said sole plate.

Claim 3

A device for braking of a ski upon release of a ski boot from a binding thereon, comprising: a sole plate mounted on said ski and adapted to normally remain therewith, said sole plate having at least one binding thereon for releasably holding said ski boot to said sole plate; a pair of separate and identically formed substantially rigid brake members, each of said brake members having an L-shape with one leg of the L defining a braking mandrel and the other leg defining a pivot shaft, said pair of pivot shafts extending generally horizontally and transversely to the longitudinal axis of said ski; bearing means on said sole plate for supporting said pivot shafts for both an axial movement and a rotatable movement; a bifurcated spring wire tensioning lever having a pair of resilient legs fixedly connected to said pivot shafts, and being pivotal therewith between a first upright position transverse to the longitudinal axis of said ski and a second position generally parallel to the longitudinal axis of said ski, said legs being flexible from a normal relaxed position inwardly toward each other and a tensioned position; a T-shaped recess on said sole plate receiving said spring wire tension lever therein, said bearing means including a pair of generally horizontally extending holes opening outwardly of said sole plate and inwardly into the cross bar portion of said T-shaped recess, said pivot shafts being received in said holes; and cam means on the walls of said T-shaped recess engaging said legs of said tensioning lever while in said tensioned position for continually urging said tensioning lever from said second position toward said first position whereat said legs are in said relaxed position whereby said tensioning lever is wholly received in said T-shaped recess when in the tensioned position thereof so that the ski boot rests directly on said sole plate.

Claim 4

A device for braking of a ski upon release of a ski boot from a binding thereon, comprising: a sole plate mounted on said ski and adapted to normally remain therewith, said sole plate having at least one binding thereon for releasably holding said ski boot to said sole plate; a pair of separate and identically formed substantially rigid brake members, each of said brake members having an L-shape with one leg of the L defining a braking mandrel and the other leg defining a pivot shaft, said pair of pivot shafts extending generally horizontally and transversely to the longitudinal axis of said ski; bearing means on said sole plate for supporting said pivot shafts for both an axial movement and a rotatable movement; a bifurcated spring wire tensioning lever having a pair of resilient legs fixedly connected to said pivot shafts, and being pivotal therewith between a first upright position transverse to the longitudinal axis of said ski and a second position generally parallel to the longitudinal axis of said ski, said legs being flexible from a normal relaxed position inwardly toward each other and a tensioned position; a T-shaped recess on said sole plate receiving said spring wire tension lever therein, said bearing means including a pair of generally horizontally extending holes opening outwardly of said sole plate and inwardly into the cross bar portion of said T-shaped recess, said pivot shafts being received in said holes; and cam means on the walls of said T-shaped recess engaging said legs of said tensioning lever while in said tensioned position for continually urging said tensioning lever from said second position toward said first position whereat said legs are in said relaxed position whereby said tensioning lever is wholly received in said T-shaped recess when in the tensioned position thereof so that the ski boot rests directly on said sole plate.
