Abstract
Abstract A braking mechanism to prevent runaway skis. At least one braking member is bent to an L-shape, one leg in the at-rest position lying parallel to the lengthwise extent of the ski and the other leg being pivotally positioned crosswise of the ski. The crosswise positioned portion is in effect threaded, as by twisting a bar of rectangular cross section, and is supported in a guide member such that pivotal movement of said L-members around said crosswise positioned leg will effect outward movement thereof. Resilient means are placed against said crosswise member to continually urge such movement. The longitudinally aligned member is normally held on the surface of the ski by the boot or ski binding, but when released it moves outwardly in response to the resilient means and as a result rotates and moves said first named leg beyond the adjacent edge of the ski and into its braking position. Though above-described as a single braking device, same are preferably provided in pairs with the legs aligned lengthwise of the ski adjacent the opposite edges thereof. Modification in the details of the mounting actuating mechanisms are also shown.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
A braking mechanism for a ski provided with a releasable binding comprising a lever pivotally mounted on the upper surface of the ski in the vicinity of the binding and adapted to be held against movement when a boot is held in the binding and to be pivoted downwardly into engagement with the surface supporting the ski when the boot is released to prevent further travel of the ski, said lever comprising a two-arm bar having one arm which extends substantially parallel to the longitudinal axis of said ski and a transverse arm which extends transversely to said longitudinal axis of said ski, said transverse arm having a twisted polygonal cross section, a guide for holding said twisted polygonal cross section of said transverse arm and having an opening therethrough corresponding in cross section to the cross section of said polygonal cross section so that an outward movement of said transverse arm through said opening will effect a pivoting movement of said two-arm bar and resilient means for urging said two-arm bar outwardly from an at rest position and pivoted into a braking position.
Claim 2
Dependent Claim
184 words
A braking mechanism for a ski provided with a releasable binding comprising a lever pivotally mounted on the upper surface of the ski in the vicinity of the binding and adapted to be held against movement when a boot is held in the binding and to be pivoted downwardly into engagement with the surface supporting the ski when the boot is released to prevent further travel of the ski, said lever comprising a two-arm bar having one arm which extends substantially parallel to the longitudinal axis of said ski and a transverse arm which extends transversely to said longitudinal axis of said ski, said transverse arm having a twisted polygonal cross section, a guide for holding said twisted polygonal cross section of said transverse arm and having an opening therethrough corresponding in cross section to the cross section of said polygonal cross section so that an outward movement of said transverse arm through said opening will effect a pivoting movement of said two-arm bar and resilient means for urging said two-arm bar outwardly from an at rest position and pivoted into a braking position.
Claim 3
Dependent Claim
53 words
A braking mechanism according to claim 1, wherein an inner edge of said bar is spaced from a side of said ski at a distance which is smaller than the path covered by said outward movement of said two arm bar in transverse direction due to said pivoting of said bar through 180*.
Claim 4
Dependent Claim
27 words
A braking mechanism according to claim 2, wherein an outer edge of said bar lies in said at rest position on the upper surface of said ski.
Claim 5
Dependent Claim
32 words
A braking mechanism according to claim 1, wherein the angle through which said bar pivots between its at rest position and its braking position is in the range of 210* and 270*.
Claim 6
Dependent Claim
86 words
A braking mechanism according to claim 1, wherein said one arm of said bar is held in said at rest position by means of a locking mechanism which is movable transversely to said longitudinal axis of said ski, said locking mechanism having a lock cooperating with said one arm, which lock is arranged on a movable locking member and movable from the locking position between a position of use and said at rest position and an operating lever for moving said locking member between said positions.
Claim 7
Dependent Claim
73 words
A braking mechanism according to claim 5, wherein said locking mechanism includes a disk rotatably supported on a holding pin, said disk having one end of at least one locking arm hingedly supported, said locking arm having a longitudinal slot which is guided on guide elements which are fixedly inserted into said ski and the end of said locking arm defines a lock and wherein said operating lever is secured on said disk.
Claim 8
Dependent Claim
17 words
A braking mechanism according to claim 6, wherein two locking arms are hingedly supported on said disk.
Claim 9
Dependent Claim
35 words
A braking mechanism according to claim 1 including two two-armed bars which are arranged on said ski one behind the other in the longitudinal direction of said ski and are spring- loaded by separate springs.
Claim 10
Dependent Claim
32 words
A braking mechanism according to claim 1, wherein the angle through which said bar pivots between its at rest position and its braking position is in the range of 225* and 240*.
Claim 11
Dependent Claim
19 words
A braking mechanism according to claim 1, wherein said one arm has an inclined surface on its free end.
