摘要:
A sealing ring for sealing about a relatively-rotatable member is an annular, disk-like ring having a root surface about one edge which is adjacent a flarable, sealing-surface zone for slidingly engaging the member. Torsion ribs project from the root surface. The inside surfaces of the torsion ribs are regular prolongations of the sealing surface and the distance therefrom to opposite, outside surfaces diminishes, preferably continuously to a knife-like edge where the inside and outside surfaces meet. The result peels liquid to be sealed in from the relatively-rotating member so that it does not destructively deform the torsion ribs even at high speeds of relative rotation.

A ski or a snowboard is in the form of a board-type gliding device. By reference to the width of the gliding device, at least one recess is provided in its middle portion extending in its depth direction from the top face of the gliding device in the direction towards the running surface facing and disposed in its longitudinal direction essentially parallel with the longitudinal direction of the gliding device with a view to causing a cross-sectional weakening. At least one manually adjustable adjusting device is provided, which is designed to produce an individually adjustable change in the load-dependent deformability of the cross-sectional shape or to produce an individually adjustable limit to the maximum permissible load-dependent cross-sectional deformation of the gliding device. Further, a ski or a snowboard is provided with a manually adjustable adjusting device which is designed to act as a spreading device for producing an individually adjustable increase in the width of the recess on the one hand and to act as a pulling device to produce an individually adjustable decrease in the width of the recess on the other hand.

The invention relates to a binding mechanism (1) for board-type gliding devices, in particular a snowboard binding, provided with a retaining plate (12) for a base plate (11) for securing it to a gliding board body. A setting and fixing device (23) is provided, which can be switched into at least three selectively assumable operating modes and is designed so that (i) in a first operating mode, an anti-rotation lock and an anti-lift lock for the base plate (11) are activated, (ii) in a second operating mode, the anti-rotation lock is inactive and the anti-lift lock is active, and (iii) in a third operating mode, the anti-rotation lock and the anti-lift lock are inactive. The retaining plate (12) is therefore rigidly connected to the top face (13) of a gliding board body and is immobile in the direction perpendicular to it both when the anti-rotation lock (41) is deactivated in order to change the position of angular rotation (20) and when the anti-lift lock (42) is deactivated in order to remove or fit the base plate (11).

The invention relates to an end piece (2, 2′) for the front or rear end of a ski (1) or snow-board, which end piece (2, 2′) has at least a first and a second portion (6, 7). A distance (10, 10′) between mutually adjacent zones (8, 9) of the first and second portion (6, 7) or a width or length measurement of at least one of the zones (8, 9) can be varied. Alternatively, the first and second portion (6, 7) are connected to one another in the mutually adjacent zones (8, 9) by means of an articulated joint and/or an elastically stretchable and rebounding bridging element and/or an elastically deformable middle portion (12) and the zones of the first and second portion (6, 7) remote from the mutually adjacent zones (8, 9) can be respectively connected to oppositely lying side edges of a ski (1) or snowboard by articulated joints and/or with an interconnected elastic deformation zone. This positively influences the performance of a ski (1) or snowboard with a variable geometry or size.

The invention describes a binding mechanism (1) for providing a pivotably moving connection of a sports shoe (2) to a board-type gliding device (3), in particular to a ski (4). The binding mechanism (1) comprises a first or front retaining element (5) for retaining the front toe-end portion of a sports shoe (2), a second or rear retaining element (6) for retaining the rear heel-end portion of a sports shoe (2) and an elongate connecting element (9) of variable shape between the first and the second retaining element (5, 6). This connecting element (9) extends underneath the sole (10) of a sports shoe (2) inserted in the binding mechanism (1). The connecting element (9) is provided in the form of a link chain (12) with a plurality of connected link parts (13) and the individual link parts (13) are articulatingly connecting to one another by means of several link joints (14) with several articulation axes(16) oriented parallel with one another, and the articulation axes (16) of the link joints (14) are oriented essentially horizontally and extend transversely to the longitudinal extension of the connecting element (9) and transversely to the binding longitudinal axis (15).
摘要:
A binding unit for a snowboard that permits an individual adjustment of angular position relative to the snowboard, includes, for fixing it to the snowboard, a substantially circular retaining disc, as seen in plan view, for a base plate of relatively large surface area. Coupling parts are mounted directly or indirectly on the base plate to provide a connection to a snowboard shoe which is releasable from the snowboard when the coupling parts are inactive or deactivated. At least one slide element on the retaining disc is displaceable between an extracted position, in which the at least one slide element at least partially covers the base plate, a portion of the slide element or elements projecting from a circular circumferential region of the retaining disc in the extracted position, and an inserted position, in which the at least one slide element does not at least partially cover the base plate.

The invention describes a ski binding (1), with guide elements (8, 9) which can be mounted or pre-fitted on a ski (3) in the binding longitudinal direction (10), for a front and a rear jaw body (4, 5). A first coupling element (15) is connected to the front jaw body (4) and a second coupling element (16) is connected to the rear jaw body (5). Mutually facing end portions (17, 18) of these coupling elements (15, 16) co-operate with a positioning and fixing mechanism (14) disposed between the jaw bodies (4, 5) in order to adjust and retain the jaw body (4, 5) as necessary. An overlap width (19) between the two coupling elements (15, 16) can be varied to make an individual adjustment for different jaw distances (12). At least one coupling element (15, 16) is provided with at least two mutually parallel rows (21, 22, 23) of positioning elements (20), and these positioning element-rows (21, 22, 23) are disposed offset from one another in the binding longitudinal direction (10). An offset distance (24) between adjacent rows (21, 22; 22, 23) of positioning elements (20) represents a step dimension for an overlap step width between the coupling elements (15, 16).

The invention relates to a positioning mechanism (1) for releasably fixing at least one position of a positioning means (3) which can be displaced more or less linearly relative to positioning means (2) fixedly connected to a structure (45), e.g. a shoe, which provides a mount for at least one displaceable coupling means (9) which engages under the action of a spring system (39) in a female coupling part (20) of the positioning means (2) connected to the structure (45) in a position which fixes the position of the positioning means (2, 3) relative to one another. The coupling means (9) is mounted in the displaceable positioning means (3) so that it can be linearly displaced in a direction perpendicular to the displacement direction of the positioning means (3) and, in a position fixing the position between the positioning means (2, 3), engages by means of a coupling projection (21) with the female coupling part (20) of the positioning means (2) connected to the structure (45) and in a positioning seat (42) disposed in the displaceable positioning means (3).
