ABSTRACT:
A U-shaped ski brake made of spring wire wherein intermediate the legs of the U, the spring wire is bent to form laterally extending axles to define a pivotal support for the ski brake. The intermediate portion of the length of the spring wire extending between the axles is also U-shaped and is connected to the inner ends of the axles. The legs of the holding bars are prestressed so that they extend, when the ski brake is in the braking position, at an angle which is greater than 90.degree. to the longitudinal axis of the axles. A slide is mounted on the holding arms and is reciprocal along the length thereof. The spacer has holes receiving the holding arms therein so that as the slider moves along the holding arms, the resiliency of the spring wire will cause the brake arms to move laterally inwardly and outwardly relative to the outer edges of the ski. The spacer is pivotally secured through a lever arm to a mounting plate, the same plate to which the spring wire is pivotally secured. A spacing between the pivotal support for the lever and the axles causes, when the ski brake is erected from the retracted position to the ski braking position, a longitudinal sliding movement of the slider along the holding arms.
