Abstract
Abstract A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally fixed toe restrainer (13) and generates, via a force deflection transmission, a longitudinal force which is dependent on the contact force which acts on the toe and which counteracts the spring force via a bar member (12). At least one lever (14) which is acted on by the vertically displaceably or pivotably arranged toe restrainer (13) acts on the same bar member (12) in the same sense with a release force which is dependent on the vertically upwardly directed force acting on the toe restrainer (13).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
269 words
A laterally releasable toe unit for a ski safety binding for securing a ski boot to a ski, said toe unit comprising first and second laterally pivotable side jaws; a yoke for holding said first and second laterally pivotable side jaws in a ski boot retaining position; a release spring disposed to bias said yoke in a direction to hold said side jaws in said ski boot retaining position, said side jaws being pivotable laterally against the spring bias to release the ski boot; a toe plate disposed to receive a toe portion of a ski boot thereon, said toe plate being movable in a direction perpendicular to said ski; a force deflecting transmission means operative between said toe plate and said spring for exerting a force on said spring against the spring bias, said force being dependent on a contact force acting on said toe plate perpendicular to said ski, said force deflecting transmission means comprising a bar member extending in the longitudinal direction of the ski and bearing against said yoke; a laterally fixedly located toe restrainer for restraining upward movement of said toe portion away from said ski, said toe restrainer being movable in an upward direction away from said ski; and at least one lever operatively associated with said toe restrainer and responsive to an upwardly directed force acting on said toe restrainer to act on said bar member to move same in a direction to exert a relief force against said spring bias in the same sense as said force deflecting transmission means exerts, said relief force being related to said upwardly directed force.
Claim 2
Dependent Claim
269 words
A laterally releasable toe unit for a ski safety binding for securing a ski boot to a ski, said toe unit comprising first and second laterally pivotable side jaws; a yoke for holding said first and second laterally pivotable side jaws in a ski boot retaining position; a release spring disposed to bias said yoke in a direction to hold said side jaws in said ski boot retaining position, said side jaws being pivotable laterally against the spring bias to release the ski boot; a toe plate disposed to receive a toe portion of a ski boot thereon, said toe plate being movable in a direction perpendicular to said ski; a force deflecting transmission means operative between said toe plate and said spring for exerting a force on said spring against the spring bias, said force being dependent on a contact force acting on said toe plate perpendicular to said ski, said force deflecting transmission means comprising a bar member extending in the longitudinal direction of the ski and bearing against said yoke; a laterally fixedly located toe restrainer for restraining upward movement of said toe portion away from said ski, said toe restrainer being movable in an upward direction away from said ski; and at least one lever operatively associated with said toe restrainer and responsive to an upwardly directed force acting on said toe restrainer to act on said bar member to move same in a direction to exert a relief force against said spring bias in the same sense as said force deflecting transmission means exerts, said relief force being related to said upwardly directed force.
Claim 3
Dependent Claim
124 words
A toe unit according to claim 1, wherein said bar member comprises a central rod having at its front end an upright lug bearing against said yoke and front and rear crossbars; the rear crossbar has an inclined surface in the vicinity of said toe plate and said toe plate has a complementary counter-surface thereon for acting on said inclined surface, the front cross bar has further upright lugs at its ends, and there is a second lever operatively associated with said toe restrainer, said one and second levers being substantially vertically arranged and said further upright lugs engaging behind said levers, and said toe restrainer is pivotably connected to an upper portion of a base member of said binding about a transverse axle.
Claim 4
Dependent Claim
46 words
A toe unit according to claim 2, wherein said bar member is formed as a stamped part, said upright lug and further upright lugs being bent-up from said stamped part, and said rear crossbar comprising a portion of said stamped part having said inclined surface thereon.
