Abstract
Abstract A ski brake having at least one pivotal blade capable of being embedded into the snow and wherein the blade is urged to an inactive position by an elastic member of low tension. An elastic return member of a step-on pedal exerts a positive action on the blade only during raising of pedal to cause the blade to travel to its active position, while freeing the blade during the descent of the pedal in order to permit the low tension elastic member to return the blade to inactive position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
Ski brake apparatus adapted for being mounted on the upper surface of a ski, said apparatus comprising a step-on pedal pivotably mounted on the ski and having a raised inoperative position and a lowered operative position, elastic means acting on said step-on pedal urging said pedal to raised inoperative position, said pedal being lowered against the opposition of said elastic means by application of a boot on said pedal, a stop arm comprising a brake lever pivotably mounted on said ski for movement between a raised inactive position and a lowered active position, said blade projecting below the ski in said active position, connection means between said step-on pedal and said blade for urging said blade to active position when the step-on pedal is moved to its raised inoperative position by said elastic means and for being disconnected from said blade when the step-on pedal is lowered whereby said elastic means has no influence on said blade, and an elastic member of lower strength as compared to said elastic means connected to said blade to urge the blade to raised inactive position when the step-on pedal is lowered to operative position.
Claim 2
Dependent Claim
191 words
Ski brake apparatus adapted for being mounted on the upper surface of a ski, said apparatus comprising a step-on pedal pivotably mounted on the ski and having a raised inoperative position and a lowered operative position, elastic means acting on said step-on pedal urging said pedal to raised inoperative position, said pedal being lowered against the opposition of said elastic means by application of a boot on said pedal, a stop arm comprising a brake lever pivotably mounted on said ski for movement between a raised inactive position and a lowered active position, said blade projecting below the ski in said active position, connection means between said step-on pedal and said blade for urging said blade to active position when the step-on pedal is moved to its raised inoperative position by said elastic means and for being disconnected from said blade when the step-on pedal is lowered whereby said elastic means has no influence on said blade, and an elastic member of lower strength as compared to said elastic means connected to said blade to urge the blade to raised inactive position when the step-on pedal is lowered to operative position.
Claim 3
Dependent Claim
22 words
Ski brake apparatus as claimed in claim 1 wherein said elastic member is independent of said elastic means and is distinct therefrom.
Claim 4
Dependent Claim
22 words
Ski brake apparatus as claimed in claim 1 wherein said connection means comprises a cable connecting said pedal and said brake lever.
Claim 5
Dependent Claim
82 words
Ski brake apparatus as claimed in claim 3 wherein said connection means further comprises a rotatable shaft, said brake lever being fixed to said shaft for rotating therewith, said cable connecting said pedal and said shaft such that raising of said pedal produces rotation of said shaft and movement of said brake lever from said raised to said lowered position, whereas lowering of said pedal results in slackening of said cable whereby the brake lever can be raised by said elastic member.
Claim 6
Dependent Claim
20 words
Ski brake apparatus as claimed in claim 4 wherein said elastic member is a torsion spring wound on said shaft.
Claim 7
Dependent Claim
84 words
Ski brake apparatus as claimed in claim 1 wherein said connection means further comprises a rotatable shaft, said brake lever being fixed to said shaft for rotation therewith, a transverse arm secured to said shaft and having a ramp surface in contact with said pedal such that raising of the pedal produces rotation of said shaft and movement of said brake lever to active position, and lowering of said pedal frees the transverse arm and permits raising of said lever by said elastic member.
Claim 8
Dependent Claim
20 words
Ski brake apparatus as claimed in claim 6 wherein said elastic member is a torsion spring wound on said shaft.
Claim 9
Dependent Claim
86 words
Ski brake apparatus as claimed in claim 1 wherein said connection means further comprises a rotatable shaft, said brake lever being fixed to said shaft for rotation therewith, a lug secured to said pedal, said shaft having a cam surface engaged by said lug such that raising of said pedal produces rotation of said shaft and movement of said brake lever to active position and lowering of said pedal separates the lug from said cam surface to permit raising of the lever by said elastic member.
Claim 10
Dependent Claim
20 words
Ski brake apparatus as claimed in claim 8 wherein said elastic member is a torsion spring wound on said shaft.
