Abstract
Abstract A ski brake including a length of spring wire of round crosssection, having a central shaft portion extending transverse to the longitudinal axis of the ski, and acting as a pivoting axis of the brake, one end portion extending beside the ski and acting as a brake spur engageable with the snow, and the other end portion being bent to form a holding loop engageable by a ski boot to pivot the brake, against its own spring action, to a rest position beside the ski.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
213 words
In a ski brake securable to the upper surface of a ski and having, laterally of the ski, a brake spur which can pivot about a pivoting axis extending on the upper side of the ski transversly to the longitudinal axis thereof and a holding lever depressible by the ski boot to hold the brake spur in its rest position, the brake spur being pivoted into its braking position by spring action upon removal of the ski boot from the ski binding, the improvement in the brake comprising a wire, bent so that one end part forms the brake spur, a central first shaft portion lying in the pivoting axis and the other end part being shaped into a holding loop forming the holding lever, said holding loop acting as a spring which moves the spur to its braking position and having two alternate positions, one position being against the ski when depressed by the ski boot and the other position extending outwardly from the ski when the ski boot is removed from the ski binding, the free end of said holding loop forming a second shaft portion which can pivot in its location about an axis arranged spaced from and parallel to the pivoting axis on the upper side of the ski.

In a ski brake securable to the upper surface of a ski and having, laterally of the ski, a brake spur which can pivot about a pivoting axis extending on the upper side of the ski transversly to the longitudinal axis thereof and a holding lever depressible by the ski boot to hold the brake spur in its rest position, the brake spur being pivoted into its braking position by spring action upon removal of the ski boot from the ski binding, the improvement in the brake comprising a wire, bent so that one end part forms the brake spur, a central first shaft portion lying in the pivoting axis and the other end part being shaped into a holding loop forming the holding lever, said holding loop acting as a spring which moves the spur to its braking position and having two alternate positions, one position being against the ski when depressed by the ski boot and the other position extending outwardly from the ski when the ski boot is removed from the ski binding, the free end of said holding loop forming a second shaft portion which can pivot in its location about an axis arranged spaced from and parallel to the pivoting axis on the upper side of the ski.
Claim 3
Dependent Claim
