摘要:
A mounting for a ski binding including a runner (1) attached to the ski and a plate (2) slidably mounted on the runner and provided with a latch (3) that may be released by means of a lever (6) pivotably mounted under the plate (2) and extending through an aperture (10) therein. The lever and/or the plate are provided with an aperture sealing means for at least approximately sealing said aperture at least when the binding is in its operative position. The sealing means consists of, e.g., a rigid portion (11) and a flexible portion (13) of the lever.
摘要:
A base intended to receive a ski binding thereon, said base comprising a slider (1) fixed to the ski, with a row of notches (4) parallel to the axis of the slider, and a fitted plate (5) sliding onto the slider, with a latch (6) engaged, by the action of a spring, in a notch of the slider, in such a way as to immobilize the plate on the slider, as well as a release lever (13). The latch (6) consists of a fitted part separate from the lever, sliding transversally to the plate, and the base also comprises a mobile element, like a shoe (16) which removes play between the plate and the slider, and may be moved to an active or inactive position by action on the release lever.

A safety ski binding comprises a releasable front jaw (11) engaging one end of the ski boot (15) and a heel jaw (12) which engages a second end of the ski boot (15). A heel jaw housing (16) is mounted longitudinally displaceably in longitudinal guides (13) affixed to the ski. Preferably, there is at least some vertical and horizontal play between heel jaw housing (16) and longitudinal guides (13). Heel jaw housing (16) is urged by at least one thrust spring (14) against the ski boot (15) which bears on the one side on heel jaw housing (16) and on the other side on a longitudinally adjustable lock member (18) which is also affixed to the ski. Between the end of the thrust spring (14) bearing on the lock member (18) and the lock member (18), a force-resolving means (20), which resolves a part of the longitudinal force (F) of the thrust spring (14) into two opposite spreading forces (S), is disposed. Spreading forces (S) act on lock member (18) in the direction of the ski (21) and on heel jaw housing (16) in the direction away from the ski.
摘要:
A lead based alloy for electrode supports of a lead-acid storage cell, the alloy containing between 0.05% and 4% antimony between 0.02% and 0.3% magnesium, and no barium. The magnesium permits a reduced antimony content, thereby reducing the corrosion, self-discharge, and hydrogen-releasing overvoltage problems caused by the presence of antimony in electrode supports, without adversely affecting the beneficial mechanical properties provided by antimony. It is essential to have no barium, which causes cracking and high mass corrosion of the alloy during use in a lead-acid cell.

A ski binding comprises a slide (2) fixed on the ski and a sliding base (4). The binding is equipped with a ski brake which can be demounted and remounted. The brake has rigid retention means in the form of two hooks (23, 24). The two hooks engage, by virtue of a longitudinal (L) then transverse (T) engagement movement, two projections (33, 34) located on a reinforcement frame (31) fastened to the base (4).
摘要:
A ski brake consisting of a hoop (2) of spring metal articulated by its sides to a base (1) and having in its central part a flattened open loop (25) bearing on the base so as to form a return spring tending to hold the brake in the active position, the central part of the hoop carrying a pedal (3) fitted so as to tilt. The pedal has a protuberance (33) which engages in the open loop (25) when the brake is in the raised position. The pinching by the loop (25) on the protuberance lifts the pedal when the pressure on the latter is released.

Holding device comprising a body (1) mounted so as to slide in a rail (4) on which it is maintained in position by means of a lock (9) that is articulated to the body (1) and is provided with an unlocking lever (20). This unlocking lever is provided with two lateral flanges (21, 22) extending toward the rail, on each side of the central region of the latter. The flanges (21, 22) are preferably divergent and their rear edge (23) is inclined. This form of unlocking lever secures the lock against accidental unlocking in the event of impact.
摘要:
A heel unit (10) of a safety ski binding comprises a unidirectional blocking arrangement (60') with at least one blocking member (62') arranged between a sole holder (16) and a spring biased return cam (26). The unidirectional blocking arrangement blocks in the opening direction and is releasable against a slight spring force (66) by means of a manual release member (64). One of the return cam (26) and the sole holder (16) is provided with a bearing face (68), generally circular or semicircular and concentric to the axis (A) of the return cam and of the sole holder for the blocking member (62') which is permanently resiliently urged into an actual blocking position.
摘要:
In a ski brake with brake arms (12) and actuating arms (14) a pedal (16) is mounted to the actuating arms (14) about a second transverse axis (15). A linkage arrangement (17) is provided approximately parallel to the actuating arms (14) and is pivotally connected to the pedal (16) about a third transverse axis (18) and to the ski about a fourth transverse axis (19). The fact that the spacing of the second transverse axis (15) from the third transverse axis (18) is somewhat smaller than the spacing between the first transverse axis (13) and the fourth transverse axis (19) means that the pedal (16) can execute a small counter-pivotal movement on transfer of the ski brake from the braking position into the rest position.
摘要:
The safety ski binding is primarily intended to retain the toe end of a ski boot and comprises a yoke pivotally mounted on a cross-pin in a stationary hollow body. The jaw unit for retaining the ski boot is guided in longitudinal sliding motion within the yoke. The jaw unit is provided with semi-cylindrical grooves directed towards the ski boot and having the function of cooperating with support rods attached to the yoke. The jaw unit is also associated with a cylindrical roller which is directed away from the ski boot and is intended to cooperate with a locking lever. The ski binding provides compensation for the parasitic friction forces which arise from complex falling movements involving forward-fall and twisting motion as well as backward-fall and twisting motion.
