Abstract
Abstract This invention provides an improved ski braking mechanism wherein the braking unit comprises a pair of Z-shaped, independently movable rods each having an outer leg attached to a braking spur, an inner leg attached to a brake pedal, and a central cross-bar forming a pivot axis. A stop is provided to inhibit the movement of the braking spurs towards the longitudinal middle section of the ski when the spurs are in the lowered braking position. Each braking spur is retractable towards the longitudinal middle section of the ski when the spurs are in the raised skiing position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
287 words
A ski brake mountable on a ski for impeding movement of the ski down a slope when the ski is detached from a skier's boot, the ski having a top surface, a bottom skiing surface, longitudinal side edges and a longitudinal middle section intermediate the longitudinal side edges, said ski brake comprising: at least one braking spur rotatable about an axis transverse to the longitudinal side edges of the ski between a raised skiing position and a lowered braking position, said braking spur having an end disposed below the bottom skiing surface of the ski for engaging the snow when said braking spur is in the braking position: an inner portion connected to said braking spur for controlling the movement of said braking spur; pedal means movable between a lowered skiing position and a raised non-skiing position, said pedal means moving said inner portion to rotate said braking spur to the raised skiing position when said pedal means is in the lowered skiing position, and to the lowered braking position when said pedal means is in the raised non-skiing position; biasing means for biasing said pedal means to the raised non-skiing position and said braking spur to the lowered braking position; housing means for housing at least part of said inner portion of said ski brake, said housing means including top means for limiting the rotation of said braking spur in said lowered braking position and for engaging said inner portion to prevent lateral movement of said braking spur while in said braking position, said inner portion being disengaged from said stop means when said braking spur is in said raised skiing position to enable lateral movement of said braking spur with respect to said housing means.
Claim 2
Dependent Claim
287 words
A ski brake mountable on a ski for impeding movement of the ski down a slope when the ski is detached from a skier's boot, the ski having a top surface, a bottom skiing surface, longitudinal side edges and a longitudinal middle section intermediate the longitudinal side edges, said ski brake comprising: at least one braking spur rotatable about an axis transverse to the longitudinal side edges of the ski between a raised skiing position and a lowered braking position, said braking spur having an end disposed below the bottom skiing surface of the ski for engaging the snow when said braking spur is in the braking position: an inner portion connected to said braking spur for controlling the movement of said braking spur; pedal means movable between a lowered skiing position and a raised non-skiing position, said pedal means moving said inner portion to rotate said braking spur to the raised skiing position when said pedal means is in the lowered skiing position, and to the lowered braking position when said pedal means is in the raised non-skiing position; biasing means for biasing said pedal means to the raised non-skiing position and said braking spur to the lowered braking position; housing means for housing at least part of said inner portion of said ski brake, said housing means including top means for limiting the rotation of said braking spur in said lowered braking position and for engaging said inner portion to prevent lateral movement of said braking spur while in said braking position, said inner portion being disengaged from said stop means when said braking spur is in said raised skiing position to enable lateral movement of said braking spur with respect to said housing means.
Claim 3
Dependent Claim
70 words
The invention of claim 1, wherein said inner portion of the ski brake comprises an inner leg and a generally Z-shaped round wire part having a cross piece interconnecting said spur and said inner leg; each cross piece comprising a pivot axis for lowering said spur from said skiing position to said braking position; and, wherein said stop means is positioned between said inner portion and said longitudinal middle section.
Claim 4
Dependent Claim
17 words
The invention according to claim 2 wherein said inner leg and said Z-shaped part is generally coplanar.
Claim 5
Dependent Claim
17 words
The invention according to claim 2 wherein said braking spur and said cross piece is generally coplanar.
Claim 6
Dependent Claim
29 words
The invention according to claim 2 wherein said inner leg is generally perpendicular to the longitudinal edges of the ski when the ski brake is mounted on the ski.
Claim 7
Dependent Claim
29 words
The invention according to claim 2 and further including means for restraining said pivot axis against longitudinal movement during movement of said end between the skiing and braking positions.
Claim 8
Dependent Claim
17 words
The invention of claim 1, wherein said stop means comprises a flange formed on said housing means.
Claim 9
Dependent Claim
34 words
The invention according to claim 1, and further including guide means for urging the braking spur toward the longitudinal middle section of the ski when said braking spur is in the raised skiing position.
Claim 10
Dependent Claim
42 words
The invention according to claim 5 wherein said inner portion of the ski brake includes inner leg, and said guide means comprises means for urging said inner leg towards said middle section when said braking spur is in the raised skiing position.
