Abstract
A retaining device is disclosed for retaining the front end of an associated boot (50) on an associated ski (3). A movable jaw (4) pivots on a base (6) around a vertical axis (7) against the action of an elastic return means (8). The elastic return means (8) includes two actuating arms (10a, 10b), acted upon by an elastic system (11). Each of the actuating arms (10a, 10b) pivots independent of the jaw (4) around a pivot axis (15a, 16b). The jaw (4) cooperates with the actuating arms (10a, 10b) via a driving element (9). The elastic return means (8) is arranged below the front end of the associated boot (50) in back of the transverse plane (T) which passes through the pivot axis (7) of the jaw (4).
Claims15
A retaining device for retaining a front end of a boot on ski, the retaining device comprising:
- a base;
- a movable jaw pivotally mounted to the base and pivoting around a vertical pivot axis;
- and
- a resilient biasing means which opposes the pivoting, the resilient biasing means including:
- a driving element,
- two independent actuating arms each of which pivot about a respective pivot point and which cooperate with the jaw through the driving element,
- as the jaw pivots about the vertical pivot axis, the driving element drives a corresponding one of the actuating arms pivotally about its respective pivot point, and
- a resilient return system arranged under the front end of the associated boot in the rear of a transverse plane passing through the pivot axis of the jaw.
A retaining device for retaining a front end of a boot on a ski, the retaining device comprising:
- a base;
- a movable jaw pivotally mounted to the base and pivoting around a vertical pivot axis;
- and,
- a resilient biasing means which opposes the pivoting, the resilient biasing means including:
- a driving element with a cylindrical driving projection extending downward with an axis,
- two independent actuating arms each of which pivot about a respective pivot point and which cooperate with the jaw through the driving element,
- as the jaw pivots about the vertical pivot axis, the driving element drives a corresponding one of the actuating arms pivotally about its respective pivot point,
- a resilient return system arranged under the front end of the associated boot in the rear of a transverse plane passing through the pivot axis of the jaw,
- a front plate which links the driving element to the jaw and which plate extends approximately horizontally,
- the driving projection being retained in a centered position by a plurality of actuating rails disposed on the two independent actuating arms, and,
- each of the plurality of actuating rails having a retaining first rail portion and a disengagement second rail portion, whereby the force required to pass the actuating element from the retaining first rail portion to the disengagement second rail portion defines a disengagement force value that releases the boot.
A ski binding comprising:
- a base;
- a boot toe retainer which releasably engages and supports a ski boot toe, the toe retainer being pivotally mounted to the base for rotation about a vertical axis adjacent a front edge thereof, such that the toe retainer pivots between a skiing position in which the boot toe is retained and a release position in which the boot toe is released;
- at least one detent extending downward from the toe retainer rearward of the pivot axis along a longitudinal axis;
- a pair of activating arms pivotally connected at front ends to the base between the pivot axis and the detent symmetrically to opposite sides of the longitudinal axis, the detent engaging both actuating arms in the skiing position and engaging only one of the arms in the pivoted boot toe releasing position;
- and
- a biasing element which biases a rearward portion of the actuating arms together to bias the toe retainer into the skiing position and which resiliently yields under lateral pressure allowing the toe retainer to pivot to the release position.
