Abstract: An expansion wedge anchor (80) for insertion in a hole (H) delimited by a wall comprises an expander member (32) and an expansion number (34), the expander member being provided at a leading end of the expander member, the expander member comprising a flaring end (40), the expansion member being expandable at a trailing end (48) thereof and being adapted to engage the wall of the hole when the expander member is positioned in the hole, wherein upon longitudinal withdrawal of the expander member from the hole, the expander member displaces longitudinally relative to the expansion member with the flaring end thereof gradually causing the trailing end of the expansion member to expand, whereby a trailing edge of the expansion member engages the wall of the hole. The trailing end is adapted, when expanded by the flaring member, to extend at an angle with respect to a longitudinal axis of said expander member.

Abstract: Device for adjusting the relative position between a first part, for example a ski binding heel-piece, equipped with a toothed strip (8) and a second part, for example a slide (2), equipped with two opposed sets of teeth (16, 17) collaborating with the sets of teeth (10, 11) of the strip. The sets of teeth of one of the parts are offset by a half-tooth and the teeth of the sets of teeth are truncated. The sets of teeth of the two parts come into mesh alternately on one side and the other, making it possible to have a pitch for adjustment equal to a half-tooth rather than a full tooth. The fineness of the adjustment is thus improved.

Abstract: The combination of a binding and boot is provided. The binding has a pair of pistons (7, 8) extending under the boot. Each piston is stressed by a spring (14, 15). The arms of a sole clamp (2, 3) act on these pistons. The pistons are connected together by a linking device (20). The combination magnetically controls the linking device which is capable of occupying a first position, in which the pistons arc secured by the linking device, and a second position in which one of the pistons is able to move on its own, at least over a certain travel common to the two pistons. The combination thus provides asymmetrical release resistance.

Abstract: A binding (8) has a lower surface (15) has a width (L5) and is mounted on an upper surface of a ski (2) of width (L2). The width of the lower surface (15) is less than or equal to the width of the ski (2). A support body (9) diverges in width along lateral boarders (19, 20) from the lower surface (15) to an upper surface (18) of width (L4). The upper surface supports an anti-friction plate (10) that defines a support zone (17) of width (L3). The width (L3) of the support zone (17) is greater than width (L5) of the lower surface (15) and the width (L2) if the ski (2).

Abstract: A support device on a ski for the front part of the sole of a ski boot is held by a releasable binding holding the front of the boot, including a support in which a support plate is slideably mounted transversely to the ski. A limiting arrangement limits the displacement of the support plate in the support and includes stops on both the support plate and the support. A transverse helical spring is engaged partially in the support plate and partially in the support and works in compression between the support and the support plate upon displacement of the support plate. A support device using a helical return spring is thereby produced in which the support plate travels substantially farther than in the prior art, while being perfectly guided and held in the support.

Abstract: A device for raising at least one element (5) of a binding used on a board (3) for gliding, including an element (4) which is articulated relative to the board and one end (30) of which comes into contact with the upper face (6) of the board. The element (5) of the binding is mounted on the articulated element (4) and the end (30) of the articulated element (4) is secured to the upper face (6) of the board by attaching member (33) so that the forces exerted vertically at the location of the binding element (5) are partly transmitted to the board (3) at the location of the end (30) of the articulated element (4).

Abstract: 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.

Abstract: A device for raising at least one element of a binding used on a board for gliding, including: a zone for mounting the binding, integral with the board for gliding; a bearing zone, extending the mounting zone in the direction of the end of the board, wherein the end of the bearing zone facing toward the end of the board is secured to the upper face of the board by an attaching means in such a manner that the forces exerted at the location of the element of the binding are partially transmitted to the board at the location of said end of the bearing zone, and which includes a transverse groove located between the mounting zone and the bearing zone so as to allow the deformation of the bearing zone when the board is bent.

Abstract: A ski binding includes a stop (3) and a heel piece (5). An elastic means opposes the release of the stop and the heel piece. The elastic means includes a blade (6) working in buckling mode between two slides (2, 4) which correspond to the stop and the heel piece, respectively. Conventional springs for releasing the stop and the heel piece are therefore replaced by this longitudinally arranged blade.

Abstract: 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).

Abstract: The assembly consists of a boot whose sole (42) is fitted with a transverse bar (38) which engages between a bearing piece (11) and a self-locking cam (29). The bearing piece (11) is secured to a sliding piece (10) and the cam (29) is mounted on a piece (19) which preferably slides. These two pieces are mounted in a rail (2, 3) while being drawn toward one another by springs (16). The bar (38) can be disengaged by means of a lever (32). This binding releases both in the event of falling forward or backward and in response to twisting.

Abstract: A binding having a binding body which has, mounted in it, at least one return spring, adjustable means for prestressing the spring, and means for indicating the prestress of the spring which consist of a cursor linked kinematically with the prestressing means and a graduation in front of which the cursor moves, the gradation and the cursor being covered by a transparent part. The body is at least partially covered with a casing (18) that forms a protective cap and has at least one transparent region in front of the gradation.

Abstract: A binding comprising a first part (1) integral with a shoe which is fastened to a second part (2) integral with the slideboard. The second part comprises, at the front, a tilting jaw (5) coming to bear on the vertical bearing surfaces (4) and against a front bearing surface (3) of the first part and, at the rear, a stirrup (20) mounted pivotably about a vertical axis by means of a second stirrup (18) and tilting about a horizontal axis. The arms of this stirrup are in the form of a hook (33) coming to bear on a pair of lateral pegs (6) of the shoe. The jaw and the stirrup bear on slides (12, 26), between which compression springs are mounted. This binding preserves the independence of the torsion and forward-fall release assembly, and it is virtually insensitive to the changes to the exposed parts of the shoe during travel without a binding.

Abstract: A binding, comprises a pair of jaws (7,8) which can be moved apart from one another laterally while pushing back a cam (13) acted on by springs (19) and additional holding means, such as a jaw (21) located in front of or behind the lateral jaws and capable of tilting, preferably about a swivel, s against the action of the springs. The binding is intended to receive a part (2) integrated with the sole of the boot. The binding further comprises a lever for intentional boot release (24).

Abstract: The heel piece of a safety binding for holding a boot on a ski, comprises a tubular binding body which is open at its two ends, is rigidly linked to a sole grip (1a) and is articulated about a transverse cam forming part of a stirrup piece (3) which is articulated onto a pivoting plate (4) joined to the ski, this body containing at least one spring which works in compression between a piston bearing on the cam, and a stop secured to a setting screw. The setting screw bears axially, by its head, against a bearing zone of the binding body, and the stop consists of a nut mounted on the setting screw, the screw, with its stop, the spring and the piston being mounted in the body through the end corresponding to the sole grip.

Abstract: A rear binding (6) releasably clamps a heel (5) of a boot (1) to a ski (2). A front binding (4) which engages a toe (3) of the boot releases under lateral force towards the left or right side of the ski. A support assembly (8) engages a sole (7) of the ski boot to reduce frictional forces between the ski boot and ski which might impair the release of the front binding. The support device includes a stationary support (9) which is mounted to the ski and which defines a lateral groove (13) having a generally inverted T-shaped cross section. A movable element (10) which is slidably received in the groove has an upper surface that supports the boot sole. A friction reducing element (20), such as a layer of low coefficient of friction plastic is disposed between the movable element and the stationary support such that the movable element and the toe of the boot can move laterally with minimum frictional resistance.

Abstract: An elastic return device for a safety ski binding comprising a coil spring (10) and having a stiffness which varies as a function of the stress rate. A deformable plastic (11) is interposed between the turns of the spring, so that the stiffness of the spring increases with the rate at which it is compressed. This elastic element makes it possible to avoid premature release of the binding.

Abstract: 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).

Abstract: 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.
