Abstract
The invention concerns braking devices for skis that will ensure their immobilization when unexpectedly separated from the ski boot. For a ski which is put on by positioning the boot at an angle and then pivoting it to lock it in place, the ski brake includes a braking element 17 mounted on a pin 17 whose extremity 21 is pushed back by the boot during pivoting so that the braking element is raised counter to the action of a spring. This arrangement facilitates placing the boot on the ski at an angle.
Claims33
Braking device for a ski equipped with a boot-retention system in which the ski is put on by placing the boot at an oblique angle to the ski and substantially parallel to the upper plane thereof, then by causing the boot to pivot in the plane of the ski about a vertical axis perpendicular to the ski to align it with the longitudinal axis of said ski, in which position the boot is rigid with the ski because of a fastening system, said braking device comprising
- (a) at least one braking element movable with respect to the ski between an inactive position in which the braking element is raised above the bottom of the ski, and an active braking position in which the braking element protrudes from the underside of the ski;
- and
- (b) control means for actuating the braking element, at least one part of which reacts to the presence or absence of the boot on the ski;
- (c) one part of said control means protruding when said braking element is in said active braking position, into a space which is to be occupied by an element associated with said boot when said boot is aligned with the longitudinal axis of the ski;
- (d) said part of said control means being a movable part moved away from said space by a pushing action applied thereto by said boot associated element, said pushing action having at least a component force oriented in a plane parallel with the plane of the ski when said boot rotates in the plane of the ski;
- (e) at least one of the elements including said part of said control means and said pivoted boot associated element having a cam profile cooperating with the other element and permitting displacement of said boot associated element relative to said part of said control means.
Braking device according to claim, 12 for equipping a pivot-type binding in which one part of the releasable fastening means of the boot against the ski is borne by said pivot, while the other part of the fastening means is integral with the boot and comprises at least one piston attracted by a spring which cooperates with the housing provided on the pivot, the braking element being mounted in the pivot which contains the passage and the slot in which are housed the fragments of the rod forming the braking element, the movable part also being housed in the pivot so that it moves about a vertical axis provided therein.
