Abstract: A ski or a snowboard in the form of a board-like sliding device, comprising a multi-layered sliding board body and at least one board-like force-transmitting element supported on the top side of the sliding board body, the upper side of which force-transmitting element is provided for supporting a binding device for a potentially releasable connection with a sports shoe. In at least one of the two lateral upper edge sections of the sliding board body running in the longitudinal direction of the sliding board body at least one interlocking coupling means is formed. Said at least one interlocking coupling means is formed by at least one physically independent strip or profile-like coupling element which is arranged between the board-like force-transmitting element and the sliding board body and is provided for forming an interlocking connection between the board-like force-transmitting element and the sliding board body.

Abstract: The invention relates to a board-like sliding device in the form of a ski or snowboard. Said board-like sliding device comprises a multilayered sliding board body and at least one elongated force-transmitting element supported on the upper side of the sliding board body for influencing the bending resistance or the vibrational behavior of the sliding board body as well as a binding device for a potentially detachable connection with a sports shoe. Between the lower side of the force-transmitting element and the upper side of the sliding board body at least one engaging coupling means is formed. The force-transmitting element is designed in this case as a thin-walled shell body with a wall thickness of less than 5 mm, which at least over the main part of its longitudinal extension has a substantially U-shaped cross section. At least part sections of the side arms of the force-transmitting element run at least partly in groove-like depressions on the upper side of the sliding board body.

Abstract: A multi-functional board-type gliding device, which has two end portions spaced at a distance apart from another in the direction of a longitudinal axis and is designed to be split in its longitudinal extension to form gliding part-devices . Several first and second coupling mechanisms are disposed in the direction of longitudinal extension in order to provide a mutual connection between the two gliding part-devices. The two mutually coupled gliding part-devices constitute a first operating mode and in the position separated from one another constitute a second operating mode. In the first operating mode in the coupled position, the two gliding part-devices form a first end portion which defines a first direction of use. In the second operating mode in the position separated from one another, the or the other end portions define a second direction of use opposite the first direction of use.

Abstract: The invention describes a ski (2) or a snowboard in the form of a board-type gliding device (1). By reference to the width (13) of the gliding board body, at least one slot (14) is provided in its middle portion extending in the depth direction—arrow (15)—from the top face (7) of the gliding board body in the direction towards the running surface facing (10) and in its longitudinal direction essentially parallel with the longitudinal direction of the gliding board body. This at least one slot (14) is provided with a view to causing a cross-sectional weakening and reducing the stiffness of the gliding board body transversely to its longitudinal direction. Also provided is at least one geometry-influencing means (19), by means of which the cross-sectional shape or contour of the gliding board body is variable as a function of load and/or can be manually varied.

Abstract: The invention relates to a method for producing an outer limiting element for a sliding board body, such as a ski or a snowboard, and a method for producing a sliding board body equipped with said limiting element. The limiting element is formed by a one-piece part component composed of at least one cover layer and at least one part of the strengthening top band. The limiting element is then connected in a subsequent method step to the additional components of the sliding board body, such as its running surface and its strengthening lower band. It is essential in this case that the limiting element prior to connection with the additional components of the sliding board body is connected to at least one strip-like side wall element forming a lateral wall section of the sliding board body, in that the at least one strip-like side wall element is adhered to at least one longitudinal side edge of the cover layer or to the top band arranged on the lower side of the cover layer.

Abstract: The invention relates to a ski (2) or a snowboard in the form of a board-type gliding device (1), comprising a multi-layered gliding board body. A force-transmitting element (13) is supported on the top face (7) of the gliding board body, the top face of which is provided as a means of supporting a binding mechanism (3) for a connection to a sports shoe which can be released as and when necessary. The force-transmitting element (13) is of a plate-type design and extends across more than 50% of the length of the gliding board body. Within its longitudinal extension, the plate-type force-transmitting element (14) is supported in at least part-portions on the top face (7) of the gliding board body so as to transmit load and is connected to the gliding board body by means of a plurality of connecting zones (30) disposed in the longitudinal direction of the plate-type force-transmitting element (13).

Abstract: A ski or a snowboard in the form of a board-type gliding device has by reference to the board body width, at least one slot in its middle portion extending in the depth direction from the board body top face towards the running surface facing and in its longitudinal direction essentially parallel with the board body longitudinal direction to cause a cross-sectional weakening and reduce the stiffness of the board body transversely to its longitudinal direction. At least one geometry-influencing device produces a cross-sectional board body shape or contour which is variable manually or as a function of load. The slot is then faced with a bridging element which is elastically stretchable or expandable, at least transversely to the longitudinal extension of the slot to prevent snow from being transferred or getting inside the slot from the running surface facing towards the top face of the gliding board body.
