Abstract
Abstract A pedal-actuated ski brake biased into the braking position and having a means for holding the brake prong inboard of the ski when in the skiing position. The ski brake may also have a means for biasing the brake prong outboard of the ski when in the braking position. When the ski brake is used with a turntable ski binding, the pedal is received inside an opening in the turntable and there is also a means for engaging the heel retainer so as to hinder unwanted movement.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
266 words
A brake for a ski, comprising: a pair of laterally spaced wire levers, each wire lever being of predetermined diameter and comprising a pivot shaft intermediate a lower arm and an upper arm, said lever being rotatable between a braking position in which said lower arm extends below the ski and outboard from the ski and a non-braking position in which said lower arm does not extend below the ski; a coil spring disposed between said wire levers for biasing said lower arms outboard from the ski, said coil spring having a diameter no larger than the diameter of either of said levers; actuating means for urging each lever into said braking position; a generally circular pedal being rotatable about an axis perpendicular to said pedal and having a thickness about equal to the predetermined diameter of said wire levers, said pedal further having a downwardly facing recess containing the coil spring and receiving the upper arms of each of said wire levers, said pedal receiving pressure from the sole of a ski boot, said pedal being movable by the pressure of the ski boot from a non-skiing position to a skiing position, said levers being rotated into said non-braking position when said pedal means is moved into said skiing position; and positioning means for holding each of said lower arms in an inboard position against the bias of said coil spring when said levers are in said non-braking position, said positioning means comprising a guide surface on said pedal for engaging and urging inward said upper arms when said pedal is in said skiing position.
Claim 2
Dependent Claim
266 words
A brake for a ski, comprising: a pair of laterally spaced wire levers, each wire lever being of predetermined diameter and comprising a pivot shaft intermediate a lower arm and an upper arm, said lever being rotatable between a braking position in which said lower arm extends below the ski and outboard from the ski and a non-braking position in which said lower arm does not extend below the ski; a coil spring disposed between said wire levers for biasing said lower arms outboard from the ski, said coil spring having a diameter no larger than the diameter of either of said levers; actuating means for urging each lever into said braking position; a generally circular pedal being rotatable about an axis perpendicular to said pedal and having a thickness about equal to the predetermined diameter of said wire levers, said pedal further having a downwardly facing recess containing the coil spring and receiving the upper arms of each of said wire levers, said pedal receiving pressure from the sole of a ski boot, said pedal being movable by the pressure of the ski boot from a non-skiing position to a skiing position, said levers being rotated into said non-braking position when said pedal means is moved into said skiing position; and positioning means for holding each of said lower arms in an inboard position against the bias of said coil spring when said levers are in said non-braking position, said positioning means comprising a guide surface on said pedal for engaging and urging inward said upper arms when said pedal is in said skiing position.
Claim 3
Dependent Claim
98 words
The ski brake of claim 1, wherein said actuating means comprises: an actuating arm operatively connected to each of said levers and movable between an actuating position wherein said levers are in said braking position and a non-actuating position wherein said levers are is in said non-braking position; and first biasing for biasing said actuating arm to said actuating position to cause said levers to assume said braking position; and wherein said pedal is operatively connected to said actuating arm, said actuating arm being moved to said non-actuating position when said pedal is moved into said non-skiing position.
Claim 4
Dependent Claim
82 words
The ski brake of claim 1 wherein said actuating means comprises an actuating arm operatively connected to each of said levers and movable between an actuating position wherein said levers are in said braking position and a non-actuating position wherein said levers are in said non-braking position; and first biasing means for biasing said actuating arm to said actuating position to cause said levers to assume said braking position; and wherein said spring and said first biasing means comprise a single spring.
Claim 5
Dependent Claim
58 words
The ski brake of claim 1 and further comprising: a turntable ski binding with a turntable having an opening for receiving said pedal when said pedal is in said skiing position, said turntable being engageable by the sole of a ski boot when said pedal is moved into said skiing position by said pressure of said ski boot.
Claim 6
Dependent Claim
30 words
The ski brake of claim 4, wherein said turntable further comprises a horseshoe-shaped boot plate for bearing weight of said ski boot when said pedal is in said skiing position.
