Abstract: Ski binding heel unit includes lateral release cams and a vector decoupler mechanism that provide lateral shear release of the heel of a ski boot from a ski. The ski binding heel unit includes an independent vertical heel release mechanism, independent lateral release mechanism and a forward pressure compensator. The lateral release cams have laterally outwardly flaring contact points. The vector decoupler mechanism restricts heel unit lateral rotation and translation to a control path. The shape of the lateral release cams dictates the control path. The vector decoupler mechanism redirects the non-lateral forces without effecting the vertical heel release, lateral heel release or forward pressure compensator. The lateral release cams and vector decoupler mechanism avert non-lateral, benign loads from the lateral heel release, and avert non-vertical, benign loads from the vertical heel release thereby reducing the incidence of inadvertent pre-release of a boot from a ski.

Abstract: A tricycle may be operable between a first mode of operation steerable by a tricycle rider, and a second mode of operation steerable by an individual pushing the tricycle. In both such first and second modes, the frame of the tricycle is configured to rotatably support the rear wheels and configured to support the head tube at a distance from the rear wheels such that a distance between the head tube and rear wheels need not necessarily be changed even when the front wheel axis location is changed from one mode to another.

Abstract: A heel piece for an alpine ski attachment comprises a base element (1), fastenable to a ski (S), an upper element (2), coupled to the base element (1), and a pair of rotatable arms for hooking to a shaped portion exhibited in a rear part of an alpine ski boot. A pair of pins (32) borne by the arms (31) project from the upper element (2). An elastic element (4) maintains the pins (32) at a predetermined reciprocal distance. The elastic element is stressed by a separation of the pair of pins (32), determined by a lowering of the ski boot onto the ski and by insertion between the pins (32) of the shaped portion. The pins (32), following complete insertion of the shaped portion between the pins, lock against an upper part of the shaped portion to hook the ski boot.

Abstract: An alpine ski binding system for releasably securing a ski boot to a ski. The binding system includes a secondary toe release that provides an attenuated release threshold under lateral shear loading conditions that can cause anterior cruciate ligament injuries. The secondary toe release responds to a trigger that senses the lateral shear loads applied to the inside (medial) afterbody of the ski and triggers the secondary toe release the boot at an attenuated release torque. Lateral shear loads applied to the ski along the leading (medial) forebody and along the entire outside (lateral side) of the ski substantially do not cause the trigger to trip.

The binding is noteworthy in that the rocking pins of the jaws (5a, 5b) are parallel to the longitudinal axis of the binding. The binding makes it possible to hold a boot having a sole that makes it easier for the user to walk.

The cam is formed in a cylindrical part which serves as a rotation pin for the body and has a flat extending parallel to the axis of said cylindrical part, with the piston bearing on this flat when the heel piece is closed. The cam has a second flat or a stop limiting the tilting of the binding body when the heel piece is being opened.

Abstract: That end of a ski boot which is retained by the boot-retaining unit is retained such that it can be disengaged in the sideways direction and vertical direction. Upon sideways movement of the ski boot within a range of elasticity of the boot-retaining unit, the ski boot is rendered capable of moving increasingly in the upward direction, strong forces in the upward direction producing a force component which additionally forces the boot-retaining unit in the sideways direction.

Abstract: A binding element adapted to retain the end of a boot. It includes a body that bears on a jaw. The jaw is vertically movable, and its movement is transmitted to the return spring of the jaw, which constitutes a compensation for a backward fall. The sole of the boot is pinched between a support plate and sole-tightener of the jaw. The support plate is movably mounted about a horizontal and longitudinal axis so that a twisting of the boot causes an elevation of the jaw and thus, activates the compensation mechanism.

Abstract: 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.

Abstract: A sideways releasable jaw of a ski binding for holding one end of the ski boot (9) has a binding housing (11) in which a release spring (14) is arranged The release spring (14) extends substantially in the longitudinal direction of the ski and is braced at one end against the binding housing (11). At its other end it exerts a release force with a substantial component in the longitudinal direction of the ski pointing away from the ski boot (9) on a sole clamp (22) arranged towards the ski boot (9). On exceeding a predetermined sideways force exerted by the ski boot (9) the sole clamp (22) can pivot sideways about a substantially upright pivotal axis and releases the ski boot (9). In so doing the release spring exerts a downwardly directed force component on the sole clamp which is vertically displaceably arranged on the binding housing (11) for movement along an upright sliding guide. Thus the sole clamp (22) is pressed against the upper side of the sole (29) of the ski boot.

An elastic device is provided for normally maintaining the jaw on its support in a central engaged position. Furthermore, a linkage device is provided between the jaw and its support for frontwardly displacing an upper portion of the jaw and rearwardly displacing a lower portion of the jaw, during movement of the jaw in a lateral direction, which is substantially transverse to the ski in all lateral released positions, so as to simultaneously cause a progressive upward opening of the jaw.

Abstract: The anti-friction plate is guided by vertical and longitudinal guidance apparatus allowing for a free lateral movement. The free lateral extent of plate 1 is limited by the play of the lateral ramps of an opening 22 which is laterally movable with the anti-friction plate 1 and in which a spur 26 affixed to jaw 6 penetrates. Spur 26 assures the recentering of plate 1 when the jaw 6 returns to the centered position, and frees the plate when the jaw is pivoted.
