Abstract: The invention relates to a sports shoe, in particular an alpine ski shoe, comprising an upper part and a sole formation. A stiffening element for influencing the stiffness of the sole formation extends between a toe side and a heel side of the sole formation. A detachable fixing element is assigned to the stiffening element and is exclusively disposed at the heel side of the sole formation, so that said fixing element can be operated from the entry for the user's foot into the sports shoe and in the detached state permits removal of the stiffening element from the interior of the upper part of shoe via the entry for the user's foot.

Abstract: A toe binding of a safety ski binding includes a housing for at least partly mounting at least one release spring determining the safety release values and at least one sole holder loaded by the force of the release spring. When an upper force threshold is exceeded the sole holder releases the front section of a boot secured by the binding at least in lateral direction relative to the boot longitudinal axis. An adjusting device is adapted for individually changing the lateral alignment between the sole holder and the housing transversely to the binding longitudinal axis of the binding and substantially parallel to the standing plane for a boot, so that an angle or a lateral deflection between the boot longitudinal axis of a boot inserted into the binding and the binding longitudinal axis of the safety ski binding can be changed and individually preadjusted within predefined adjusting limits.

Abstract: The invention relates to a shell part of sports shoe and a method for producing such a shell part based on joining together several components made preferably of different materials in one or more injection molding processes. The method comprises: the production of at least one three-dimensional stable shoe reinforcing part, the application of a filler material on the inner side of the shoe reinforcing part; the positioning of the shoe reinforcing part on a last; and the at least partial overmolding of the shoe reinforcing part with plastic. The method enables the simple and easily controllable production of a shell part with very high rigidity or stability at least in specific areas and at the same time also ensures the workability or adjustability of the shell part during the production and afterwards.

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.

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.

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 running surface for a cross-country ski or similar generic ski, which running surface has a climbing aid profile within a part-portion of its length to prevent backward sliding, which comprises a plurality of consecutive step profiles in the longitudinal direction of the running surface, which are of a saw tooth design as viewed in longitudinal section through the running surface. A flank height of the saw tooth step profiles extending transversely to the longitudinal direction of the running surface increases or decreases continuously or discontinuously by reference to the longitudinal direction of the running surface. Also specified is a cross-country ski or similar generic ski equipped with this running surface. The features proposed by the invention result in an improved ratio between the gliding and kick-off behaviour of the running surface.

The first tightening element (15) is designed to bear against the peripheral sections of the comparatively flexible inner shoe (3) or its tongue (17) and the further tightening element (16) is designed to bear against the upper end section of the shoe collar (5) made of a relatively rigid plastic.

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.

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.

Abstract: The invention relates to a method for machining the running surfaces (9) of winter sports appliances such as skis or snowboards, in which a blank track (20) is subjected to a machining process in order to obtain a predetermined surface microstructure which improves the gliding ability. A precisely defined and reproducible surface structure of the track is achieved in such a way that the machining process for producing the surface microstructure comprises a plastic deformation by a tool (5, 5a) which is moved over a running surface (9) of the track blank (20) and is pressed with a predetermined force on the track blank (20) in order to deform the same in a plastic manner. The invention further relates to a winter sports appliance which is produced with such a method and an apparatus for performing the method.

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 behaviour 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.
