Abstract: A process for manufacturing a ski comprises the steps of providing a shell with a substantially U-shaped cross section, a top strap being integrated into the shell, the shell having a base and shanks extending downwardly and outwardly at an angle to the base, placing a ski core in between the shanks, but not contacting either the shanks or the base, placing a bottom strap on and spanning the space between the outwardly projecting ends of the shanks, and filling all hollow spaces between the core, the shell, and the bottom strap with a liquid plastic material to bond the core, the shell and the bottom strap.

Abstract: A top strap for a ski comprising more than one layer and integrated in a shell of a substantially hat-shaped profile cross-section defining a hollow space housing a core, the shell having a base forming the surface of the ski and shanks extending downwardly from the base and inclined at an angle with respect thereof, the shanks forming the side faces of the ski and having ends remote from the base. One of the layers is a cover layer, another one of the layers is a reinforcement layer, the cover layer and the reinforcement layer extending along the cross-section of the whole length of the hat-shaped profile, and a further layer is an intermediate layer arranged in the region of the base of the shell and facing towards the core, the intermediate layer consisting of a reinforcement material.

Abstract: A monitoring and/or controlling device (31) for a coupling device (6) between a boot (3) and a piece of sports apparatus (1), in particular a ski binding for a ski. The monitoring and/or controlling device (31) is provided with a visible and/or acoustic display device (28), a measuring device (26) and an energy source. The measuring device (26) cooperates with a coupling device, the release mechanism of which being adjustable to different release forces for the release of the boot or the piece of sports apparatus and/or the boot. The measuring device (26) is built to record the position of the coupling device (6) and/or the coupling elements (7', 8') of the coupling device (6) relative to one another and/or relative to the ski (2) or to the boot (3).

Abstract: A ski comprises a laminated top strap integrated in a U-shaped shell, a bottom strap including a running surface layer and at least one additional reinforcement layer, and running edges along the two sides of the running surface layer and abutting free ends of the shanks of the U-shaped shell along a longitudinally extending line running in a horizontal plane of contact between the running edges and shank ends. The shell and the bottom strap define an inner hollow space and a ski core is arranged in this space. Support elements are arranged on the upper and lower core sides, the support elements defining longitudinally and transversely extending recesses therebetween and between the upper and lower core sides and the top and bottom straps.

Abstract: A ski with a profiled top with a core located between a top strap, a bottom strap and a pair of side faces. An intermediate ply is located over the top strap and underneath a top running surface ply. The intermediate ply or the core, or both, has a varying shape over the length of the ski. The intermediate ply additionally includes a damping element formed therein.

Abstract: A ski binding for a longitudinally extending ski including a forked toe clamp including two fork prongs for holding a front part of the ski boot. The forked toe clamp is rotatable around an axis. The ski binding also includes a forked heel clamp for holding a rear part of a ski boot. A tension screw spring and a slot are provided. The forked heel clamp is guided in the longitudinal direction by the slot and is biased toward the toe clamp by the tension screw spring. A centering apparatus formed as two flexible spring devices and are located on the two clamps between the two fork prongs. The force of the spring devices is approximately equal to the force of the tension screw spring so that, when the forked toe clamp is rotated, the spring devices prevent the ski boot from moving in the longitudinal direction toward the axis.

Abstract: An adjustable coupling device for coupling a ski boot to a ski. The coupling device has a longitudinal axis and includes a toe binding, a heel binding and length adjustment device. The length adjustment device is capable of altering the distance between the toe binding and the heel binding along the longitudinal axis to accommodate different-size ski boots. The length adjustment device has a first drive element connected to the toe binding and a second drive element connected to the heel binding. The drive elements can be moved and set at a position corresponding to the length of the ski boots. An attachment device is provided to attach one of the bindings to a surface of the ski at one of several preset positions in such a manner that the remainder of the coupling device can move freely in a direction perpendicular to the surface. Alternatively, the attachment device may attach both of the bindings to the surface.

Abstract: The invention relates to a ski binding (1) with a toe-holding unit (2) and a heel-holding unit (3). Release mechanisms (8) are integrated in the latter and can be set to different releasing forces. Detachably fastened on the ski are longitudinal guidance devices (5, 6) for the toe-holding and/or heel-holding unit (2, 3), which are movably connected to the connecting element (4). The toe-holding and/or heel-holding unit (2, 3) can be fixed by an arresting device (17) for fixing the toe-holding unit (2) in a longitudinal guidance device (5) and/or a transverse guidance device (74).

Abstract: A coupling device between a ski boot and a ski having a top surface and a toe binding. The toe binding engages the ski boot and is pivotal around a first axis which is perpendicular to the top surface of the ski. The coupling device also includes a heel binding for engaging the ski boot. A carrier device having a front end, a back end and two sides, is located between the toe binding and the heel binding for supporting the ski boot. The carrier device is pivotal around a second and third axis which are arranged along the back end of the carrier device and are parallel to the first axis. Also, connection means are provided for operatively connecting the toe binding to the front end of the carrier device so that the carrier device can pivot around one of the axes jointly with the toe binding pivoting around the first axis.

Abstract: The invention provides a ski binding comprising a toe piece and a heel piece for retaining a ski boot on a ski, a longitudinal guiding device for at least one of the pieces, the guiding device being affixed to a mounting surface of the ski and the piece being arranged in the guiding device for displacement in the longitudinal direction of the ski. A releasing mechanism is incorporated in each piece and is adjustable to respond to varying releasing forces for releasing the ski boot from the ski. A connecting device interconnects the toe and heel pieces for movement relative to each other, the connecting device including at least two pivotal levers, one of the levers being a connecting element pre-adjustable to a desired length, and respective pivots extending vertically to the mounting surface and connecting the toe piece to the connecting device and the pivotal levers to each other.
