Abstract: The pedal includes a pedal body (1) rotationally mounted on a pedal shaft. The pedal body (1) includes a fixed front catch element (4) and a movable rear catch element (6) that work with a retaining plate (3) fixed underneath the footwear of the cyclist. The movable rear catch element (6) is mounted to be able to pivot between a retaining position of the plate (3) and a position of release of the plate (3) by the pivoting of the rear catch element (6) in opposition to the action of an elastic return element (10). The elastic return element (10) is composed of an elastic leaf that forms a spring located in a longitudinal housing (11) of the pedal body (10) open to the rear, the leaf (10) being able to be stressed along its longitudinal axis in buckling during pivoting of the rear catch element.

Abstract: A device for mounting a wheel of a bicycle on a frame, including: an inner hub rotatably mounted in a portion of the frame, an outer hub forming a central zone of the wheel, a quick-tightening mechanism that includes a male portion projecting from a first of the inner and outer hubs, a female portion provided in a second of the hubs, axial abutments for retaining the outer hub supported against the inner hub, and a mechanism for positioning the axial abutments, the positioning mechanism not being active upon completion of the tightening of the wheel. The quick-tightening mechanism is equipped with a lever that is pivoted by the operator to provide the necessary force for the axial tightening of the outer hub of the wheel against the inner hub. In a particular embodiment of the invention, the axial abutments include a plurality of balls, and the mechanism for positioning the axial abutments include ramps on which the balls roll.

Abstract: A device for mounting a wheel of a bicycle onto a frame, including an inner hub rotatably mounted on the frame and equipped with an inner axial support area, an outer hub connected to the rim of the wheel by means of traction spokes, compression spokes, or flanges, and including an outer axial support area that cooperates with the inner axial support area, a mechanism for tightening the outer hub on the inner hub, the inner and outer axial support areas being located at a distance from the axis of the wheel at least greater than 20 mm, or greater than 25 mm, and distributed along the vicinity of a circle having a radius greater than 25 mm, centered on the axis of the wheel. The inner and outer axial support areas include a plurality of teeth forming part of a transmission mechanism.

Abstract: A bicycle that includes front and rear single-arm forks enabling the front and rear wheels to be mounted and demounted from the frame of the bicycle without necessitating the removal or repositioning of a transmission element, such as a chain, or the brake, if the bicycle is so equipped, each of the wheels including at least one flexibly and compressively rigid element connecting the central hub and the rim, such elements being asymmetrical with respect to a radial median plane defined by the rim, so that the hubs of the wheels are axially off-centered in relation to the radial median plane of the rim, while the radial median plane of the rims coincides with the general median plane of the frame. The invention is also directed to the wheel of the bicycle.

Abstract: Interface plate (1) intended to be secured to the upper face of a ski and capable of accommodating the toe piece and the heel piece of a safety binding, characterized in that it has a longitudinal recess forming a slideway capable of holding projecting parts situated under the toe piece and under the heel piece, while allowing the toe piece and the heel piece to slide inside the slideway with a view to adjusting the binding to the length of the boot, and in which the profiles (10, 11; 12, 13) of the zones of the slideway respectively holding the toe piece and the heel piece are geometrically identical.

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: 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 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).
