Toe stop member for ski safety bindings

Claim 2

A safety ski binding comprising a frame fixable onto a ski to be angularly fixed against movement in the plane of the ski, first and second rearwardly extending jaws pivotally mounted on the frame about first and second axes perpendicular to said plane of said ski, a front end of each jaw having a hollow camlike surface, a first and second rollers, elastic means for urging said first and second rollers along lines of action passing at least approximately through said first and second axes into said hollows to releasably hold said jaws in an operative boot gripping position in which said jaws can fit around at least a part of the toe end of a ski boot, said elastic means comprising first and second levers articulated together about a common eccentric axle perpendicular to said plane of said ski, said first and second levers carrying said first and second rollers, and means for angularly adjusting the eccentric axle so as to enable adjustment of separation of said first and second rollers and the separation of said first and second jaws when in the operative position.

Claim 3

A safety ski binding, according to claim 1, in which each of said jaws is formed of a hollow pressed part having a rearward extension adapted to fit over the sole of a boot, said camlike surface being formed by two edges profiled to form said hollow, a third and fourth rollers mounted with said first and second jaws about said first and second axes form abutment means, and first and second torsion springs mounted about said first and second axes to urge said jaws towards operative position.

Claim 4

A safety ski binding, comprising a frame fixable onto a ski so as to be angularly fixed against movement in the plane of said ski, first and second rearwardly extending jaws pivotally mounted on the frame about first and second axes perpendicular to said plane of said ski, a front end of each jaw having a hollow camlike surface, a first and second rollers, elastic means for urging said first and second rollers along lines of action passing at least approximately through said first and second axes into said hollows to releasably hold said jaws in an operative boot gripping position in which said jaws can fit around at least a part of the toe end of a ski boot, each of said jaws being formed of a hollow pressed part having a rearward extension to fit over the sole of a boot, said camlike surface being formed by two edges profiled to form said hollow, a third and fourth rollers mounted with said first and second jaws about said first and second axes to form abutment means, and a first and second torsion springs mounted about said first and second axes to urge said jaws towaRds operative position and said elastic means comprising a first and second levers articulated together about a common axle perpendicular to said plane of said ski, said first and second levers carrying said first and second rollers, a spring urging said first and second levers, and means for adjusting the pressure of the spring.

Claim 5

A safety ski binding, comprising a frame fixable onto a ski so as to be angularly fixed against movement in the plane of said ski, first and second rearwardly extending jaws pivotally mounted on the frame about first and second axes perpendicular to said plane of said ski, a front end of each jaw having a hollow camlike surface, a first and second rollers, elastic means for urging said first and second rollers along lines of action passing at least approximately through said first and second axes into said hollows to releasably hold said jaws in an operative boot gripping position in which said jaws can fit around at least a part of the toe end of a ski boot, each of said jaws being formed of a hollow pressed part having a rearward extension to fit over the sole of a boot, said camlike surface being formed by two edges profiled to form said hollow, a third and fourth rollers mounted with said first and second jaws about said first and second axes to form abutment means, and a first and second torsion springs mounted about said first and second axes to urge said jaws towaRds operative position and said elastic means comprising a first and second levers articulated together about a common axle perpendicular to said plane of said ski, said first and second levers carrying said first and second rollers, a spring urging said first and second levers, and means for adjusting the pressure of the spring.

Claim 6

A safety ski binding, comprising a frame fixable onto a ski to be angularly fixed against movement in the plane of said ski, first and second rearwardly extending jaws pivotally mounted on said frame about a first and second axes perpendicular to said plane of said ski, each of said jaws having a hollow camlike surface at its front end, a first and second rollers, elastic means urging said first and second rollers along lines of action passing at least approximately through said first and second axes into the hollows of said camlike surfaces to releasably hold said jaws in an operative boot gripping position in which said jaws can fit around at least a part of the toe end of a ski boot, said frame comprising a baseplate fixable in said plane of said ski, a part hinged to said baseplate, and means for angularly adjusting said part in relation to said baseplate, whereby an angular displacement of said part causes a raising or lowering of said jaws in relation to the plane of said ski.

Claim 7

A safety ski binding, comprising a frame fixable onto a ski to be angularly fixed against movement in the plane of said ski, first and second rearwardly extending jaws pivotally mounted on said frame about a first and second axes perpendicular to said plane of said ski, each of said jaws having a hollow camlike surface at its front end, a first and second rollers, elastic means urging said first and second rollers along lines of action passing at least approximately through said first and second axes into the hollows of said camlike surfaces to releasably hold said jaws in an operative boot gripping position in which said jaws can fit around at least a part of the toe end of a ski boot, said frame comprising a baseplate fixable in said plane of said ski, a part hinged to said baseplate, and means for angularly adjusting said part in relation to said baseplate, whereby an angular displacement of said part causes a raising or lowering of said jaws in relation to the plane of said ski.

Claim 8

A safety ski binding according to claim 4, in which said means for angularly adjusting said part comprises a screw mounted perpendicularly on said baseplate, a nut having a flange threadably engaging said screw, said part having an aperture engaged by said flange, a cylindrical body passing through said aperture, a head, a compression spring acting between said head and said part to urge said part towards said flange, whereby said jaws can be adjusted to a height suitable for a particular boot but can be raised from the adjusted position to accommodate for an effective increase in the thickness of the sole of the boot.
