in a simplified representation of a partial longitudinal section of the snow gliding board of FIG. 1 ,

In the figures, 1 is a snow sliding board in the form of a ski (eg alpine skis). The snow sliding board 1 or its sliding board body 2 have - apart from below special features described - the usual structure, ie consisting of a lower tread component with the tread 3 and steel edges, not shown, from a core 4 of a snow gliding or

Skis suitable core material (for example, plastic foam and / or wood) with a torsion box of fiber-reinforced plastic surrounding the core, not shown in the figures and from a shell forming the top 5 and the two longitudinal sides 6 of the ski or sliding board body 2. Furthermore, the gliding board body 2 also contains the usual supporting layers or straps which extend in the vicinity of the running surface 3 and the upper side 5 of the gliding board body 2 in this over the entire sliding board body length.

The snow sliding board 1 is designed in the illustrated embodiment as a so-called 3D ski, i. the sliding board body 2 is provided on its upper side 5 with a bead-like projection 7 and 8, of which the projection 7, starting from a central region of the sliding board body or a binding area 9 in Gleitbrettkörperlängsrichtung L up to near the trained as a blade front Gleitbrettkörperendes 2.1 and the projection 8 extending from the binding region 9 of the near to the rear sliding board body end 2.2.

Within the projection 7, underneath the shell forming the upper side 5, in the two with their longitudinal extent oriented respectively in the longitudinal axis L and e.g. formed by pipe sections made of plastic channels 10, which are arranged with their axes in a common plane parallel to the tread 3 and starting from the binding region 9 of the waisting of the longitudinal sides 6 following diverge slightly. Within each channel 10 is axially movable a trim rod 11 in the form of a carbon tube, i. provided in the form of a carbon fiber reinforced plastic tube. Each trim rod 11 is axially supported at its end remote from the binding region 9 via a damping element 12 on a sliding body-side damping mount 13 into which the peg-like damping element 12 engages with one end and which is received within the sliding board body 2.

Each trim rod 11 is further provided at its end with a Trimmstabseitigen damping receptacle 14, which with a pin-like portion 14.1 in the Trimmstab 11 engages and forms at its on the trim rod 11 protruding portion 14.2 a recess into which the pin-like damping element 12 engages with its other end. The damping receptacles 13 and 14 are for example molded parts made of a suitable plastic or at least partially made as a rotating parts of a suitable material. The damping element 12 are each molded parts of a damping, permanently elastic material, for example of an elastomer.

In the area of the projection 8, within the gliding board body 2, there is also provided e.g. Channel 10 formed by a pipe section, in which a trim rod 11 is received axially movable, which is axially supported with its the binding region 9 remote end in the same way via damping mounts 13 and 14 on a damping element 12.

At the binding area 9, a binding plate 15 is anchored to the Gleitbrettoberseite 5, which serves for fastening the binding or binding elements, not shown, and this is provided with appropriate fasteners, such as threaded holes, in the illustrated embodiment with the fasteners 16 or threaded holes for a front binding element and with fastening means 17 or threaded holes for a rear binding element. The trim rods 11 in each case extend with their end facing away from the blade region 2.1 or the rear region 2.2 to approximately the middle region of the binding plate 15, i. into a region between the fastening means 16 and 17 and are supported there on a respective bearing piece 18.1 or 19.1 axially. The bearing 18.1 is for the two trim rods 11 in the front ski area, i. for the extending between the binding region 9 and blade portion 2.1 trim rods 11 provided together. The bearing piece 19.1 is associated with the trim rod 11, which extends between the binding region 9 and the rear Gleitkörperende 2.2.

Both bearing pieces 18.1 and 19.1 are each part of a clamping device 18 and 19, which has a wedge 18.2 and 19.2 as clamping elements, in an axial direction perpendicular to the longitudinal axis L and parallel to the plane of the sliding surface 3 by means of a clamping screw 18.3 or 19.3 is movable and rests with a wedge surface against a wedge surface of the associated bearing piece 18.1 and 19.1, so that when adjusting the respective wedge 18.2 and 19.2, the mechanical axial compressive stress of the bearing against the bearing piece 18.1 or 19.1 supporting pressure rods 11 can be increased or reduced.

In the binding plate 15, a guide 20 or 21 is provided for each clamping device 18 and 19, respectively. In the guide 20, the bearing piece 18.1 in the direction of the longitudinal axis L and the wedge 18.3 are guided on the binding plate 15 supporting perpendicular to the longitudinal extension and parallel to the plane of the tread 3 slidably. In an analogous manner, in the guide 21, the bearing piece 19.1 guided in the direction of the longitudinal axis L and the clamping wedge 19.2 perpendicular thereto and supported on the binding plate 15. The two clamping screws 18.3 and 19.3 are based with their head on the binding plate and engage with its thread in an internal thread of the clamping wedges 18.2 and 19.2, wherein the clamping screws 18.3 and 19.3 each on a longitudinal side of the binding plate 15 and the sliding board 2 by an opening for an adjusting tool, such as a screwdriver are accessible.

The elements of the clamping devices 18 and 19 are made for example of metal or a suitable plastic. The binding plate 15 is made of metal or a suitable plastic, for example.

The tensioning device 18, the trim rods 11, the two damping elements 12 and the damping mounts 13 and 14 form a front trimming device 22. Analogously, the tensioning device 19, the trim rod 10, the damping element 12 and the associated damping mounts form a rear trim device 23. The special feature is that the tensioning and adjusting devices 18 and 19 are provided individually for both trimming devices and thus it is possible to adjust the properties of the sliding board body 2 in the front and in the rear area independently, ie individually.

A special feature continues to be that the clamping devices 18 and 19 are in the binding area 9 or on the binding plate 15, between the front and rear binding element and thus in the case of use of the snow gliding board below the ski boot. This results in a very simplified and in particular reliable training of the trim devices 21 and 23, since the binding plate 15 can be used as a bearing for the elements of the adjustment or clamping devices 18 and 19 and in use case these clamping devices are protected under the sole of the ski boot , In order to prevent ingress of snow and water, the educational plate is formed so that the guides 20 and 21 are sealed to the outside and only supporting itself on the binding plate 15 adjusting screws 18.3 and 19.3 at its head piece by preferably closable openings for an actuating tool ( Eg screwdriver) are accessible. In order to achieve the most effective trimming effect, the trim rods 11 are each arranged above a neutral zone of the sliding board body 2, i. Above a zone in which no or substantially no mechanical tensile and / or compressive stresses occur during bending or flexing of the sliding board body 2.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention.

It has been assumed above that the damping elements 12 are molded parts made of an elastically damping material, for example elastomer. As damping elements 12 but also other resilient or damping elements may be used, for example spring elements, such as compression springs.
