The invention relates to a linear drive with a pneumatic or hydraulic lifting cylinder, the piston rod (10) of which is fixed, the movable and longitudinally guided cylinder (6) being the load-bearing and driving part of a lifting transmission gearing which converts the relative motion between the cylinder (6) and its longitudinal guide and transmits it to the linearly movable driver (1). It is advantageous to guide the driver (1) on the outside of a slotted tube (3), the driver (1) projecting by its lug (2) into the slot of the tube (3) and being rigidly connected to the internal lifting transmission gearing. The tube (3) surrounding the cylinder (6) serves as a longitudinal guide for the cylinder (6). The lifting transmission gearing comprises, for example, two pulleys (5) secured on the cylinder (6) and the circulating rope (8) which is firmly connected, on the one hand, to the driver (1) and, on the other hand, is held on the tube (3) at an anchorage (9). In a preferred embodiment, the cylinder (6) has a continuous piston rod secured at both ends. In this solution, it is the piston rod which provides longitudinal guidance for the cylinder (6). <IMAGE>

Foot plate for a ski binding

Foot plate for a ski binding, mounted pivotably on the ski about a pivot (3) and equipped with a guide member for retaining the foot plate against the ski. These guide members comprise a metal plate (20) mounted slidably beneath a piece fastened to the ski, such as a yoke (21). The opposite transverse edges (20a, 10b) of this plate are engaged and slide in grooves in the foot plate (1). The tensile force on the yoke is independent of the longitudinal position of the plate. Such a mounting is particularly advantageous for a foot plate in two parts (4, 7) which can be displaced relative to each other, one carrying a fixed grip (5) for holding in place the front part of the boot, and the other a heel unit (8).

Sole support for a shoe

The heel support (6) makes it possible to adjust to various heights and lengths of a sole. It comprises a heel support housing (11) with a front part (13) which presses on the edge of the heel end of the ski boot sole and so fixes the ski boot on the safety binding. An opening lever (10) has a lower part (28) which slides on a curved part (27) of the heel support housing. The opening lever (10) is mounted to be pivotable about an axis (16), a torsion spring (20) likewise being wound about this axis. The heel support housing (11) is mounted to rotate about an axis of rotation located at the end of steel supports (7, 8) for fixing the heel support housing to the ski binding. A shackle (17) guided through the heel support housing (11) serves, in an opened position of the heel support housing, to close the latter. The bearing pressure of the front part (13) of the heel support housing is the same for every height of the sole of the ski boot. By means of the steel supports (7, 8) connected to the heel support housing (11) and by means of clamping brackets interacting with the latter, the heel support (6) can be adapted to the respective length of the ski boot. The heel support is easily constructed from a few components and can be economically produced. It is used particularly with plate-type ski bindings. <IMAGE>

Safety binding for ski boot

A safety binding for a ski boot having a sole clamp divided into two sole clamps ( 3, 4 ) each mounted pivoting about a particular more or less vertical axis. The sole clamps ( 3, 4 ) form two levers of a first type with two diverging arms designed to retain the boot laterally and two substantially converging arms perpendicular to the longitudinal axis. Each sole clamp is provided with a descending arm ( 9, 10 ) which bears against two adjacent points on the end of a piston ( 13 ). The piston is axially mounted in the body ( 1 ) of the binding and extends beneath the boot. A spring is biased against the piston. The descending arms ( 9, 10 ) simultaneously control the elastic tilting of the sole clamp in a vertical plane.

Ski safety binding

Binding intended for binding the front of the boot or the heel, comprising a body (13) which pivots (14) or is stationary and provided with a grip (15) articulated on the body about a horizontal pin (16). The body and the grip are held in the closed position by at least one spring (18) acting via a piston (17) on a transmission device comprising two moving parts articulated on each other (21, 24). One of these moving parts (21) bears permanently against the grip and the other moving part (24) bears permanently against lateral-retention means which consist, for example, of two stationary stops (10) against which bear levers (33a) acting on a transmission element (26). A lateral displacement of the body, or of the boot respectively, in particular causes the vertical pressure of the grip on the boot to be reduced.

Ski binding for releasing boot from pivotable plate

SAFETY SKI BINDING ABSTRACT OF THE DISCLOSURE Safety ski binding including an intermediate plate and improved boot gripping means. A plate intermediate the boot and ski is mounted onto the ski by centrally positioned pivot means and held normally aligned with the ski by heel means which permits only limited swiveling movement of the plate with respect to the ski and only limited movement vertically of the plate away from the ski. Conventional toe engaging means are provided between the plate and the ski boot and said heel means also engage the heel of the ski boot, said means being arranged for releasing the ski boot from the plate upon movement of the plate a predetermined distance either vertically away from the ski or pivotally laterally of the ski. The ski boot is thus freed from said plate and said plate remains with the ski. After the ski boot is so freed from the ski the plate returns to its aligned position with respect to the ski and the apparatus is ready for re-engagement of the boot therewith.
