Description

Stiffening and / or damping element for a sliding device, in particular for a ski or snowboard

The invention relates to a sliding device as described in the preamble of claim 1.

The invention has for its object to provide a device with which a rapid change or adaptation of the deformation behavior or the hardness of the gliding device to different operating conditions, in particular hard or soft, prepared and / or unprepared slopes, is possible.

This object of the invention is achieved by the features of claim 1. The advantages resulting from the features of the characterizing part of claim 1 are that the sliding device, in particular a ski or snowboard, enables rapid variation or adaptation to given conditions of use by the properties, in particular the resistance to deformation and / or the hardness can be changed quickly and easily. This is possible above all by means of a stiffening and / or damping element arranged in the sliding device, the stiffness of the sliding device being able to be changed over the entire cross section or in part by arranging one or more of these elements, in a first initial state by arranging in embedded in an enveloping, resilient packing a damping effect and in a further state, after evacuating the receiving chamber from the ambient pressure, a stiffening effect of the sliding device can be achieved if necessary. This means that an exact edge grip, harmonic tension curve, good damping properties against impacts perpendicular to the barrel or surface of the gliding device, as well as good deformation properties when cornering, can be achieved.

An embodiment according to claim 2 is possible, whereby a component having a plurality of functions can be produced from simple standardized and inexpensive components, with which the driving behavior of a sliding device can be influenced in a targeted manner.

An embodiment according to claim 3 is also advantageous, because if necessary a partial adjustment of the hardness or deformation properties influencing the driving properties can be influenced. According to the advantageous developments, as described in claims 4 to 6, a harmonic stress curve and a uniform deformation over wide cross sections can be achieved with the inexpensive to produce enveloping element or stiffening and / or damping element over wide areas of the sliding device during a load.

An embodiment is also possible, as described in claim 7, whereby play compensation between the components involved can be achieved, in particular in the evacuated state.

The designs according to claims 8 and 9 are also advantageous, as a result of which a metered amount of packing elements in the evacuated state can be distributed uniformly over the volume of the enveloping element or the receiving chamber.

According to claim 10 is a material or cost-saving design of the

Stiffening and / or damping elements or the envelope elements possible.

The design according to claim 11 makes it possible to form an inexpensive, easy-to-fill envelope element from standard products.

In the embodiments according to claims 12 to 14, it is advantageous that the reinforcing element having the stiffening and / or damping element or envelope elements, in cooperation with these, has a high strength, in particular a high tensile and / or compressive and / or bending strength, the glider is accessible.

Through the development according to claim 15, an additional increase in the deformation resistance of the sliding device is achieved.

The configurations according to claims 16 to 18 prove to be advantageous, since the stiffening and / or damping elements can be assigned to individual areas of the sliding device depending on the area of application.

A simple evacuation of the receiving chamber in the enveloping element can be achieved by the designs according to claims 19 to 21, the lowering of the internal pressure compared to the ambient pressure by means of a standardized, inexpensive evacuation device, which is, for example, detachably mounted on the sliding device or is formed by an external service device.

An embodiment according to claim 22 is also possible, as a result of which the number of individual components and the associated manufacturing outlay can be reduced.

However, the designs according to claims 23 to 27 are also advantageous, as a result of which the effect of the rigidity or the damping can be influenced in a targeted manner. Furthermore, all fillers that can be produced as mass products can be used.

Another embodiment according to claim 28 is also advantageous, since in particular the loads acting on the sliding device, such as tensile or compressive loads, can be better absorbed in the outer edge zone of the sliding device, as a result of which the driving behavior, in particular the hardness or the deformation resistance, is better different conditions can be set or adjusted.

According to claim 29, standardized inexpensive products can be used.

Through the training according to claims 30 and 31, it is possible to use standardized, low-cost mass products for the transmission element, as a result of which an inexpensive design of the sliding device can be achieved. In addition, such cross-sectional shapes have a large section modulus which increases the bending stiffness.

In the embodiment according to claim 32, it is advantageous that an effective influence on the driving behavior can be achieved by spanning or covering a partial area of the sliding device.

The development according to claim 33 ensures that a predeterminable driving behavior, in particular in its hardness and / or deformation resistance, can be influenced in a targeted manner.

Through the designs according to claims 34 and 35, a different driving characteristic can be achieved through the use of shaped bodies with different properties in the enveloping elements, over several partial areas or cross-sectional areas of the sliding device. Another advantage lies in the space-saving bending and torsionally rigid design of the sliding device.

The configurations according to claims 36 and 37 are also advantageous, since by shortening the spaced-apart fastening points, higher loads can be absorbed for the transmission element extending between them.

Furthermore, the refinements according to claims 38 and 39 prove to be advantageous, since prestress can be achieved by a length of the transmission elements or the support elements which is larger than the distance, and thus always on the enveloping element or reinforcing element arranged between two transmission elements arranged one behind the other. and / or damping element adjoins or is supported on the latter, thereby additionally increasing the damping or stiffening effect.

The refinements according to claims 40 and 41 enable the exact positioning or holding of the enveloping element or of the stiffening and / or damping element in the abutment or in the further transmission element, as a result of which, if necessary, an additional application of adhesive layers between the layer of the enveloping element and the surface of the further part to be connected to this can be avoided.

According to claim 42, an enlargement of the contact surface of the plate element which is in engagement with the enveloping element or stiffening and / or damping element is achieved, as a result of which the loads or forces or moments acting on the sliding device are distributed over a wide area of the device.

An embodiment according to claim 43 is also possible, by means of which the segmentation of the

Recess in the abutment or in the transmission member is achieved in several chambers, whereby a relative movement of the support element relative to the abutment or the transmission member is permitted when loads occur.

Finally, however, an embodiment as described in claim 44 is also possible, as a result of which an elastically resettable, reversible support element is formed between at least one transmission element and the abutment or between two transmission elements arranged one behind the other, as a result of which the supporting self-stiffening embodiment is suitable for the vibration-excited sliding device decaying vibration amplitude results. The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description being able to be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, laterally etc. refer to the figure described and illustrated immediately and are to be transferred to the new position in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

A jointly designed or constructed sliding device 1 according to the invention is shown in plan view or in section in the jointly described FIGS. 1 and 2. This sliding device 1 can form a ski 2 or else a snowboard or a skid etc., depending on the selected length and width ratio. With a ski 2, there is above all a greater length-width ratio than a so-called snowboard.

An upper side 3 of the sliding device 1 which is visible in plan view or in the position of use - according to FIG. 1 - is preferably of profiled or contoured design. A profiling 4 extends almost without interruption over the entire length to near the end regions 5, 6 of the sliding device 1. If necessary, the profiling 4 can also run out in a central region 7 of the sliding device 1 or in a binding assembly region 8 thereof or in the flat central region 7, which acts as a mounting platform serves for a corresponding bond. Starting from an optionally flat, plateau-like central region 7, the profiling 4 on the upper side 3 of the sliding device 1 extends in any case close to the end regions 5, 6. The profiling 4 is more pronounced in the central region 7 or in the zones adjoining the binding assembly region 8 than in the end regions 5, 6 of the sliding device 1. In particular, the profiling 4 gradually runs out with increasing proximity to the two end regions 5, 6 of the sliding device 1. This means that the profiling 5 flattens out continuously as it approaches the end regions 5, 6 and finally merges into flat end regions 5, 6. At least one so-called blade of the sliding device 1 is then formed in the end regions 5, 6.

The profiling 4 on the upper side 3 is formed by at least one, preferably two, bead-like strands 9, 10 which run essentially parallel to one another. Alternatively, it is also possible to provide three or more such strands 9, 10 running in the longitudinal direction of the sliding device 1.

A more or less pronounced depression 11 is formed between two strands 9, 10 running in the longitudinal direction of the sliding device 1. The base or the bottom of the depression 11 can be essentially V-shaped or U-shaped in cross-section, i.e. be formed with a largely flattened, flat sole area. Instead of a vault-like profile 4, which, when viewed transversely to the longitudinal direction, forms at least one arcuate elevation on the upper side 3 of the sliding device 1, it is of course also possible to use other profiling rods 4. So it is e.g. it is also possible to flatten the bead-like strands 9, 10 in the region of the upper vertex and thereby to obtain trapezoidal strands 9, 10 in cross section. Likewise, inverse configurations are possible with reference to the depression 11 or to the strands 9, 10, a bead-like strand then running in the central region of the sliding device 1 and two channel-shaped depressions being pronounced in the top 3 of the sliding device 1 on both sides of the bead-like strand.

At least one reinforcing element 12, 13 is contained in the composite body of the sliding device 1. Each strand 9, 10 or each elevation 14, 15 is preferably each a reinforcement Kungselement 12, 13 assigned. The reinforcing elements 12, 13 are preferably, if appropriate, completely integrated in the sliding device 1, ie enclosed on all sides by the other components of the sliding device 1.

If necessary, it is also possible for the reinforcing element (s) 12, 13, for example in the central region 7 or in the binding assembly region 8 or in the connection zones of the binding assembly region 8 or in one between the central region 7 and the end regions 5; 6 let area lying out of the composite body or sandwich element. For this purpose, the reinforcement elements 12, 13 can run close to the top 3 of the sliding device 1 and can be at least partially inspected by means of transparent partial areas in the manner of viewing windows 16 or recesses 17 on the top 3 of the sliding device 1.

A longitudinal extension of the profiling 4 on the upper side 3 of the sliding device 1 is only slightly larger than a longitudinal extension of the integrated reinforcing elements 12, 13.

This means that the length of the reinforcing elements 12, 13 is only slightly smaller than the longitudinal extent of the profiling 4. The length dimensions of the integrated reinforcing elements 12, 13 are therefore also decisive for the longitudinal extent of the profiling 4 on the upper side 3.

The reinforcing elements 12, 13 preferably extend, if appropriate, continuously between a front contact zone 18 and a rear contact zone 19 of the sliding device 1.

In the force-neutral state or in the idle state, the sliding device 1 is between the two

Support zones 20, 21 arched upwards in an arc.

Because of the so-called preload of the sliding device 1, it does not rest on the sub-surface 22 in the central region 7 in the unloaded state or only under the influence of its own weight. This is brought about by the so-called preload height of the sliding device 1, which is defined by the greatest distance between a running surface 23 of the sliding device 1 and a flat bearing surface under the influence of the dead weight of the sliding device 1.

A possible construction of the sliding device 1 according to the invention is shown in FIG. 2. Out This cross-sectional representation shows in particular the layer structure and the cross-sectional shapes of the individual components or elements of the sliding device 1.

As is known per se, the outer edge zones of the sliding device 1 are formed by a cover layer 24 forming the upper side 3 and a tread covering 25 forming the tread 23. The cover layer 24 forms the upper side 3 and, if appropriate, also the longitudinal side walls 26, 27 of the sliding device 1 which are oriented perpendicular to the running surface 23. The longitudinal side walls 26 and 27 of the sliding device 1 can, as is known per se, be designed to run parallel or convex. Steel edges 28, 29 represent a lateral boundary of the running surface 23. Instead of the cover layer 24 formed into a shell component, which forms the surface and the side cheeks of the sliding device 1 in a monocoque construction from a single part, it is of course also possible to use the side cheeks of the To form sliding device 1 by separate elements.

The profiled cover layer 24 preferably rests with its two longitudinal edges on a steel edge 28; 29 or on an intermediate layer of high-strength material.

A plurality of layers, in particular at least one lower flange 30 closest to the tread layer 25 and / or at least one upper flange 31 closest to the cover layer 24, are arranged between the cover layer 24 and the tread covering 25. The lower flange 30 and / or the upper flange 31 are made of a high-strength material and are placed near the edge zones of the sliding device 1 in relation to the cross section of the sliding device 1. The lower chord 30 and / or the upper chord 31 has, among other things. due to its spatial position in the sliding device 1, it has a significant influence on the rigidity or flexibility of the sliding device 1.

The upper flange 31 is adhesively connected to the cover layer 24 by means of a filler or adhesive layer 32. Likewise, the mutually facing flat sides of the lower flange 30 and the tread covering 25 are adhesively bonded to one another via a filler or adhesive layer 32. The lower flange 30 can extend, as shown schematically, between the anchoring extensions 33, 34 of the steel edges 28, 29 integrated in the sliding device 1. As an alternative to this, it is also possible for the lower flange 30, which is designed essentially as a band-like, flat component, to extend beyond the anchoring extensions 33, 34 and to be flush with the longitudinal side walls 26, 27 of the sliding device 1. In contrast to the largely flat bottom flange 30, the top flange 31 is preferably profiled. The top flange 31 is preferably shaped in such a way that it forms at least one, preferably two, elevations 14, 15 running in its longitudinal direction with an intermediate recess 11. In cross-section, the upper chord 31, which is formed, for example, from a flat workpiece, is designed to be wave-shaped.

This cross-sectional waveform, preferably with two elevations 14, 15 and the recess 11 lying between them, is dimensioned such that lower longitudinal edges 35 to 37 of the shaped upper flange 31 are arranged at a distance 38 from the steel edges 28, 29 or the lower flange 30 can. This distance 38 prevents the profiled upper flange 31 from resting on the steel edges 28, 29 or on the lower flange 30.

This distance 38 is primarily determined by at least one core component 39 of the sliding device 1. This distance 38 is kept largely constant even when force is exerted on the upper side 3 and / or on the running surface 23, apart from the relatively small permitted compression paths of the sliding device 1. The core component 39 is located between the load-bearing straps, in particular between the lower flange 30 and the upper flange 31. The core component 39 therefore distances the lower flange 30 from the upper flange 31 and forms together with the other layers of the entire sliding device 1 by means of filler or adhesive layers 32 in between a one-piece composite or sandwich element.

The space between the lower and upper chords 30, 31 remaining around the reinforcing elements 12, 13 is filled with a filler 40, preferably through a plastic porous structure. The filler 40 preferably also has an adhesive effect, so that it adheres to the adjacent components and thereby ensures the coherent, one-piece construction of the multi-part sliding device 1.

The filler 40 can also form a foam core 41 for the sliding device 1. The reinforcement elements 12, 13 and the filler 40 or the foam core 41 form the core component 39. The reinforcement elements 12, 13 can be embedded in the filler 40 or in the foam core 41. The low elasticity or flexibility of the filler 40 or of the foam core 41 is selected such that it does not break when the sliding device 1 is deformed to the maximum and cracks are excluded.

That or the reinforcing elements 12 which are preferably arranged in the apex of the approximately congruently shaped partial area of the upper chord 31; 13 are preferred by one or more at least partially overlapping hollow profiles 42, 43 and at least one receiving chamber 45 filled with packing 44 and at least one enveloping element 46 enclosing it airtight or vacuumtight are formed. The hollow profiles 42, 43 preferably have different cross-sectional dimensions, so that the hollow profile 42 is enveloped or at least partially encased by the hollow profile 43. The envelope element

46 can be formed, for example, by an elastic restoring and deformable layer 47 or film. For the hollow profiles 42; 43, all materials known from the prior art, such as plastics or metallic materials, can be used. Preferably, the hollow profile 43, which may be made of a metallic material, has on an inner side 48 facing the enveloping element 46 or the hollow profile

42 has an elastic layer 49 on a surface facing the hollow profile 43. The hollow profiles 42, 43 delimit one or more stiffening and / or damping elements 50 arranged between them, which for example extend over a large part of the length of the sliding device 1.

Of course, there is also the possibility, in the longitudinal extension and / or in a transverse direction of the sliding device 1, between the recess 11 and the longitudinal side wall 26 or the longitudinal side wall 27 a plurality of reinforcing elements 12 arranged one above the other and / or one behind the other and / or next to one another and / or one above the other; 13 to be arranged in the foam core 41. In the exemplary embodiment shown, tubular hollow profiles 42, 43 are provided, for example, which have a circular cross section in a plane perpendicular to their longitudinal extension. With reference to individual cross-sectional planes in the longitudinal direction of the sliding device 1, the respective cross-sectional shapes and / or the cross-sectional dimensions of the integrated reinforcing elements 12; 13 at least approximately adapted to the respective cross-sectional shapes or to the profiling 4 of the upper side 3 of the sliding device 1 in the individual longitudinal sections. The fillers 44 arranged in the stiffening and / or damping element 50 form a reversible when the pressure level in the receiving chamber 45 of the enveloping element 46 changes, between a first state in which it takes the form of a circular cross-section, as shown in this exemplary embodiment, and one second state by lowering an internal pressure in the enveloping element 46 to an ambient pressure - evacuation - adjustable stiffening and / or damping element 50, which in its evacuated state is at least partially connected to the reinforcing element 12; 13 forms a positive transmission and / or torque transmitting element. This makes it possible to increase the rigidity or the deformation resistance of the sliding device 1 in individual areas or over wide areas. A venting and / or venting hole 51 protruding in the receiving chamber 45 of the enveloping element 46 is connected to the flow by means of a removable or fixed to the sliding device 1 but not shown evacuation device 52, which the stiffening and / or damping element 50 via an optionally manually operable vacuum pump pressurized, which pumps out the air present in the receiving chamber 45 and lowers the pressure therein relative to the ambient pressure. The filling bodies 44, which may have an elasticity, are moved towards one another and supported against one another by the pressurization and thereby form a dimensionally stable stiffening and / or damping element 50. The evacuation of the receiving chamber 45 of the enveloping element 46 results in a slight result

Reduction of the cross-sectional dimensions of the stiffening and / or damping element 50, which essentially forms a circular cross-section, as a result of which a difference or a cavity between the layer 47 and the inside 48 of the outer side of the layer 47 or film of the covering element 46 facing the hollow profile 43 Hollow profiles 43 is formed, which is filled by an elastically resettable layer 49 arranged on the hollow profile 43 and thereby mutual support between the individual components is achieved. Due to the arrangement of a manually operable backflow valve 53, the rigid or dimensionally stable state can be eliminated by ventilation, and therefore with a pressure adjustment between the receiving chamber 45 and the ambient pressure, the receiving chamber 45 of the enveloping element 46 with the evacuation device 52. A

Flow connection between the receiving chamber 45 and e.g. a vacuum pump is implemented via a supply line 54. The ner reinforcing element 12, which is positioned directly between the underside of the upper chord 31 and on the upper side of the lower chord 30 and is positioned by them, forms with the length of the reinforcing element 12; 13 on the top and / or underside a linear friction lock, whereby no additional positioning elements for fixing the reinforcing elements 12; 13 during the foaming process, therefore required for the injection of the filler 40 for the foam core 41.

The filling bodies 44 arranged in the receiving chamber 45 of the enveloping element 46 are formed, for example, from hard materials, such as plastics from polystyrene etc., or by an open-cell plastic foam. The fillers 44 are preferably formed by a solid, in particular in the form of a sphere or a cylinder, etc. Of course, the packing 44 can also be made from a recycled product. The fillers 44 expediently have a core and a jacket surrounding them, the Core has a higher strength or a lower elasticity than a sheath enveloping it at least in regions. In particular, the core is coated with a resiliently deformable material. Of course, all other configurations of the filling bodies, which are already known from the prior art, can be used for filling the enveloping element 46 of the stiffening and / or damping element 50.

The enveloping element 46 can have a plurality of film layers which are connected to one another in a vacuum-tight manner in a circumferential edge region and which enclose or form the receiving chamber 45.

In a first state, in which ambient pressure prevails in the receiving chamber 45, loads, such as those which occur during driving, can be partially absorbed or absorbed by the damping element 50, these being transmitted to the innermost hollow profile 42 from a determinable degree of the load , As a result, in the first state, a damping element 50 formed with a damping or deformation property is formed and thereby enables a softer driving behavior. In the first state - initial state - the layer 47 of the enveloping element 46 borders on the inside 48 of the hollow profile 43 or on the surface of the hollow profile 42 or lies at least in some areas on it, as a result of which the filler bodies 44 have an elastic component when loaded Allow a relative movement between the hollow profile 43 and the hollow profile 42 and a large or the entire proportion of energy is absorbed by the filler bodies 44 during the journey, thus enabling a damping property and a smooth driving behavior. By applying a negative pressure, suction of the air in the receiving chamber 45 causes the packing elements 44 to be supported against one another and thereby forms a stiffening element designed with a higher resistance to deformation

50 off. As a result, in the second state, a relative movement in the longitudinal direction of the sliding device 1 between the hollow profiles 42 and 43 is prevented and, to a certain extent, a positive connection is formed between them, which distributes the loads or forces that occur during travel evenly over the entire cross-section and thereby a sliding device 1 forming a high deformation resistance.

Another embodiment variant, not shown further, is that the reinforcing element 12; 13 is arranged at a distance from at least one underside or top side of the upper chord 31 or lower chord 30 and is held at least in regions with the lower chord 30 or upper chord 31 by additional means. This makes an inadmissible total slipping of the reinforcing elements 12; 13 avoided during the manufacture of the foam core 41.

As shown in broken lines in FIG. 2, at least one reinforcing element 12 or 13 can be assigned to the sliding device 1 on each elevation 14 or 15 and / or in the depression 11 of the upper side 3.

In Fig. 3 is another embodiment for the construction of a sliding device 1 with the reinforcing element 12 according to the Invention; 13 or stiffening and / or damping element 50, wherein the same reference numerals have been used for parts already described above and the above explanations can be applied analogously to the same parts with the same reference numerals.

In contrast to the previous embodiment, the upper components of the sliding device 1 lying opposite the running surface 23 do not extend over the shell

Core component 39, but a relatively narrow portion of the filler 40 or the foam core 41 on the long sides walls 26, 27 of the sliding device 1 can be seen. In particular, the upper components of the sliding device 1 are angled flange-like on their longitudinal edges facing the steel edges 28, 29, so that the narrow sides of these components form a partial region of the longitudinal side surfaces. Here you can

Reinforcing elements 12; 13 are arranged in the core component 39 between the depression 11 and the longitudinal side wall 26 and / or the longitudinal side wall 27 and / or in the region of the depression 11 on the upper side 3 of the sliding device 1, as is not further shown. These reinforcing elements 12; 13 and stiffening and / or damping elements 50 are integrated lying flat in the sliding device 1 and / or on the

Slider 1 constructed. The hollow profile 42, which has a circular cross section, preferably extends over a large part of the length of the sliding device 1, which extends at least in regions in the longitudinal extent of the hollow profile 43 in one or more partial sections of the sliding device 1, for example between the central area 7 and one of the end areas 5 and / or 6 (not shown in Fig. 3). The outer hollow profile 43, which at least in regions overlaps with the hollow profile 42, has an elliptical or oval cross section in the same cross-sectional plane, the straight line connecting the tip regions of the oval hollow profile 43 is oriented essentially parallel to the running surface 23 of the sliding device 1. The cross-sectional dimensions of the inner hollow profile 42 are compared to the cross-sectional dimensions of the ses at least in some areas delimiting hollow profile 43, so that the inner hollow profile 42 is completely taken up in cross-section and is completely embedded in the stiffening and / or damping element 50. The reinforcing element 12; 13 can adjoin the underside of the upper chord 31 and / or the upper chord of the lower chord 30, as shown in this exemplary embodiment.

Instead of an elliptical cross-sectional shape, it is also possible, as indicated by dashed lines, to design the outer hollow profile 43 to be semicircular or portal-shaped in cross-section, the curved partial area facing the approximately congruently shaped upper flange 31 and the largely flat base part facing the largely flat lower flange 30 , The advantage of the elliptical or semicircular cross-sectional shape of the hollow profile 43 or possibly of the hollow profile 42 is that it can be adapted over a large circumferential area to the undulating contour of the top flange or the top side 3 of the sliding device 1. As a result, in the evacuated state of the receiving chamber 45 in the enveloping element 46, an extensive positive connection between the stiffening and / or damping element 50 and the hollow profiles 42, 43 is achieved and the glider structure can thereby withstand higher shear forces, tensile forces, bending forces or twists or these take up.

At least one of the hollow profiles 42; 43, in particular the hollow profile 43, is made of elastically resettable deformable plastics, so that a cavity formed between the latter and the stiffening and / or damping element 50 in the evacuated state is formed. The envelope element 46 or the layer 47 arranged between the hollow profiles 42 and 43 and enclosing the stiffening and / or damping element 50 in an airtight manner adjoins the inside 48 of the hollow profile 43 in the first state - initial state. A surface of the hollow profile 42 facing the inside 48 forms part of the enveloping element 46 of the stiffening and / or damping element 50. Of course, a part of the enveloping element 46 can also be formed from the inside 48 or surface of the hollow profile 42, or the enveloping element 46 formed by a layer 47 or film enclosed on all sides, which as such forms an independent component which, if appropriate, between the hollow profiles 12; 13 or is arranged directly in the core component 39.

Another embodiment variant, not shown further, consists in that the hollow profiles 42, 43, which have an elliptical or oval cross section, refer to them Cross-sectional shape are integrated upright in the composite body of the sliding device 1. In particular, a straight line connecting the tip regions of the oval hollow profile 42, 43 runs essentially perpendicular to the running surface 23 of the sliding device 1. The reinforcing element 12; or the reinforcing elements 12 having the stiffening and / or damping element 50; 13 can, for example, on the underside of the upper chord 31 and / or on the upper side of the lower chord

30 adjoin and / or be arranged at a distance from them. The evacuation of the receiving chamber 45 takes place via a supply line 54 formed by the hollow profile 42 and the ventilation and / or ventilation hole 51, as a result of which no additional effort for the attachment of supply lines 54 for the application of the negative pressure in the receiving chamber 45 is required. The hollow profiles 42 and / or 43 can of course have any cross-sectional shape.

The dimensionally stable stiffening and / or damping element 50 formed in the evacuated state forms a positive connection with the hollow profiles 42, 43, which have a high resistance to deformation and therefore in particular tensile and / or pressure and / or

Can be exposed to shear forces etc.

The advantage of this embodiment lies in the fact that a large force and / or torque-transmitting contact surface is formed between the mutually facing surfaces of the hollow profile 42 and the inside of the hollow profile 43. ..

For the hollow profiles 42, 43 all materials known from the prior art, e.g. Plastics, glass fiber reinforced plastics, composite plastics or metallic materials, in particular aluminum, titanium or corresponding metal alloys are used.

Of course, the supply lines 54 can be in the longitudinal and / or in a transverse direction, the superimposed and / or successive and / or parallel to each other reinforcing elements 12; 13 or the receiving chambers 45 of the stiffening and / or damping elements 50 are brought together to form an externally accessible connecting line.

Another embodiment variant, not shown further, consists in that the stiffening and / or damping element 50 is arranged in a hollow profile 42 or hollow profile 43, the receiving chamber 45 of which accommodates the filler body 44, with the inside surface of the Hollow profile 42 or the inside 48 or inside surface of the evacuable envelope element 46 or the receiving chamber 45 adjoins it in the initial state. Of course, when using a metallic material, the inner surface or the outer surface of the hollow profile 42 facing away from it can be coated with an elastically recoverable material.

4 and 5, the sliding device 1 is shown in various views and in a highly simplified, schematic representation. As shown schematically in FIG. 4, the sliding device 1 is equipped with at least one stiffening and / or damping element 50, preferably with two receiving chambers 45 connected to one another adjacent to the central region 7. The stiffening and / or damping element 50 extends over at least part of the length and / or width of the sliding device 1. The reinforcing element 12; 13 formed flat stiffening and / or damping element 50 is preferably arranged in an area nearer the top chord 31 in the core component 39. The upper side of the enveloping element 46 adjacent to the upper chord 31 preferably runs parallel to the approximately congruently shaped upper chord 31, and the base part arranged opposite this runs essentially parallel to the largely flat lower chord 30. The stiffening and / or stiffening and / or damping element 50 in the upper half of a half thickness 55 of the sliding device 1. The envelope element 46 filled with the filler body 44 is preferably formed by an elastically resettable deformable film which surrounds the filler body 44 on all sides. The receiving chamber 45 of the stiffening and / or damping element 50, which is enclosed on all sides by the enveloping element 46, is flow-connected to the evacuation device 52 (not shown), which is arranged, for example, on the upper side 3 of the sliding device 1. This is formed, for example, by a manually operable vacuum pump which, when actuated, pumps or sucks off the air present in the receiving chamber 45 of the stiffening and / or damping element 50 and thus reduces the internal pressure present in the receiving chamber 45 to a pressure which is lower than the ambient pressure. By arranging a manually operated backflow valve 53 in the evacuation device 52, this evacuated state of the stiffening and / or damping element 50 can be eliminated by venting the receiving chamber 45. The flow connection between the evacuation device 52 and the receiving chamber 45 is, as shown in this exemplary embodiment, via a central ventilation hole 51 and the supply line 54. Of course, there is also the possibility that the sliding device 1 is located opposite one another in a direction transverse to the longitudinal extent arranged, separated by webs receiving chambers 45 are formed, which are optionally supplied via at least one ventilation and / or vent hole 51. Of course, the receiving chambers 45 can also be produced by welding points arranged in regions.

Another embodiment variant is that in the receiving chamber 45 of the stiffening and / or damping element 50 there is at least one hollow profile 42 which increases a resistance to deformation, which on the one hand forms a reinforcing element and on the other hand the flow channel for the flow connection between the evacuation device 52 and the receiving chamber 45. Of course, the envelope element 46 can also be surrounded by a one-part or multi-part hollow profile 46, as not shown, at least in regions, against which the stiffening and / or damping element 50 is supported in the initial state. Of course, there is also the possibility that the enveloping element 46 is constructed in multiple layers and that at least one layer pointing in the direction of the core component 39 can be elastically deformed, which fills a cavity between the enveloping element 46 and the core component 39 that results in the evacuated state, whereby the directly adjoin individual components and in turn form a positive stiffening element 50.

It should be noted that in all of the design variants, the distance formed in the evacuated state between the casing element 46 and the core component 39 or hollow profile 42; 43 is essentially formed by only a few tenths of a millimeter.

Another embodiment, not shown, of a sliding device 1, in particular a snowboard, consists in that this in the cover layer 24 or between the cover layer 24 and a tread surface 25 is at least one in the longitudinal direction and in a direction transverse thereto, reinforcing elements 12, 13 or a Forms stiffening and / or damping element 50. A plurality of reinforcing elements 12 spaced apart from one another are preferably arranged transversely to the longitudinal direction of the snowboard. The longitudinally oriented reinforcing element 13 can be attached in the same and / or in a cross-sectional plane above and / or below as the reinforcing element 12. The reinforcing element 12; which may have the stiffening and / or damping element 50; 13 can also be operated via an evacuation device 52 and supply lines 54, the receiving chambers 45 of which are evacuated if necessary. The function of the actuation has already been described in detail previously. It is particularly advantageous in this configuration that, due to the large number of reinforcing elements 12 arranged transversely to the longitudinal extent of the snowboard, ski or the like, partially different degrees of hardness or deformation resistances can be set, since in each receiving chamber 45 of the enveloping element 46 different fillers 44 can be introduced if necessary ,

The webs which optionally separate the receiving chamber 45 into a plurality of subchambers can be arranged, for example, in the region of half a width, measured transversely to the longitudinal extent of the sliding device 1, of the stiffening and / or damping element 50.

As can be seen in FIG. 4, the hollow profile 42 extends over at least part of the length of the sliding device 1 or between two or more stiffening and / or damping elements 50 arranged one behind the other. An advantageous embodiment lies primarily in the arrangement of at least one with one Width and a length formed flat stiffening and / or damping element 50, which extends over at least part of the length and width of the sliding device 1.

Of course, several flat stiffening and / or damping elements 50 can also be arranged one above the other. This preferably cuboidal stiffening and / or damping element 50 is preferably manufactured in one piece from a resettable deformable film or layer 49, the stiffening and / or damping element 50 in the longitudinal direction thereof and / or in a crosswise and / or perpendicular to it Direction, therefore in the direction of the thickness 55 of the sliding device 1, forms a plurality of subchambers separated from one another by separating webs. The stiffening and / or damping element 50, which may have a plurality of layers 56 and 57, is each formed with a receiving chamber 45 enclosed on all sides by the enveloping element 46, the receiving chambers 45 of which can be filled with fillers 44 having the same and / or different properties. Of course, the filling element 46 can also be formed by several layers having different elasticities. A layer 56 and / or 57 can of course also have a plurality of receiving chambers 45.

Of course, it is also possible to distance the airtight envelope elements 46 from one another, so that in the core component 39 a plurality of envelope elements 46 spaced apart from one another, which, if required, form a plurality of separate dimensionally stable stiffening and / or damping elements 50 when an internal pressure in the envelope element 46 is reduced under an ambient pressure. The mutually separate enveloping elements 46 are optionally connected to the evacuation device 52 by two separate supply lines 54, via which the receiving chamber 45 of the enveloping elements 46 can be evacuated or subjected to negative pressure or ambient pressure. A variation in the deformation stiffness of the sliding device 1, in particular in the bending, pressure, torsional stiffness etc., can be influenced on the one hand by the level of the negative pressure to be applied, by the design or properties of the filler bodies 44, so that for different areas of application or operating conditions Different driving properties, in particular degrees of hardness and / or deformation properties, by means of which stiffening and / or damping elements 50 can be set.

A further possible embodiment of the sliding device 1 according to the invention is shown in FIG. 6. This cross-sectional representation shows in particular the layer structure and the cross-sectional shapes of the individual components or elements of the sliding device 1.

As is known per se, the outer edge zones of the sliding device 1 are formed by a cover layer 24 forming the upper side 3 and a running surface 23 arranged opposite the latter, which forms the running surface covering 25. The approximately flat cover layer 24 forms the upper side 3 and, if appropriate, also the longitudinal side surfaces 26 and 27 of the sliding device 1 which are aligned perpendicular to the running surface 23. Steel edges 28, 29 represent a lateral boundary of the tread 23. Between the cover layer 24 and the tread covering 25 there are several layers or insert elements or layers, in particular at least one lower flange 30 closest to the tread covering 25 and / or at least one upper flange closest to the covering layer 24 31 arranged, each via a filling or

Adhesive layer 32 is connected to this. Further layers 58, 59, which essentially form the core component 39, are preferably formed between the upper chord 31 and the lower chord 30. The core component 39 consists of a plurality of schematically indicated, glued and pressed strips 60 made of wood. The individual strips 60 are connected to one another via filler or adhesive layers 32 or glue layers or synthetic resins. Of course, it is also possible that the core component 39 can consist of a sandwich component, for example consisting of different types of plastic foams or a corresponding aluminum construction or the like.

The upper chord 31 points in the direction of the longitudinal extent of the sliding device 1 and in the belt device of the tread 23 at least one, preferably a plurality of mutually spaced transverse to the longitudinal direction of the sliding device 1, in cross-section approximately trapezoidal extensions 61, each protruding into a recess 62 formed by the layer 58 or 59, oriented in the direction of the tread 23. Of course, the extensions 61 and the recesses 62 can have any desired cross-sectional shapes, such as, for example, rectangular, triangular, etc. cross-sectional shapes. The layer 58 can be formed from all materials known from the prior art, such as, for example, plastics, glass fiber-reinforced plastics, composite plastics or metallic plastics, in particular aluminum, titanium or corresponding metal alloys or knitted fabrics, or woven fabrics. Of course, it is also possible for only one extension 61 and a reset 62 corresponding to this to be arranged between the upper flange 31 and the layers 58, 59. A distance 63 of the upper chord 31 and the layer 58 which is measured perpendicularly between the side flanks serves to accommodate at least one stiffening and / or damping element 50 arranged between them, the surface of the layer 58 facing the upper chord 31 or the surface of the upper chord facing away from the cover layer 24 31 one

Forms part of the vacuum-tight envelope element 46 delimiting the receiving chamber 45.

At least one ventilation and / or ventilation bore 51 or supply line 54 protrudes into this receiving chamber 45, which is flow-connected to the evacuation device 52.

As can also be seen in FIG. 6, the second evacuated state is shown schematically and in a highly simplified manner. The cavity, which is formed in the evacuated state and is shown in greatly enlarged form, between the enveloping element 46 and the surface of the upper chord 31 is filled, for example, by a coating of the upper chord 31 or by an independent, elastically resettable deformable layer, so that between the upper chord 31 and the layer 58 a positive stiffening element 50 is formed.

The upper belt 31 can be formed, for example, from a coated aluminum pressed part or an aluminum cast part or a corresponding hard aluminum or steel insert, the

Coating is formed from an elastically resettable deformable material. However, it is of course also possible for the upper chord 31 or the casing element 46 to be constructed in multiple layers and to form its own high-strength, elastically deformable plastic part.

As a result, there is no or only a slight relative movement between the upper chord 31 and the layer 58 allows.

If the internal pressure in the casing element 46 is adapted to the ambient pressure, the slight distance or cavity which compensates for the elastic layer 58 of the upper chord 31 becomes between the casing element 46 of the stiffening and / or damping element 50 and the surface of the upper chord 31 retractive envelope element 46 formed.

When a load occurs, as occurs while driving, relative movements between the upper belt 31 and the layer 58 or the layer 59 are caused. This enables smooth driving behavior with the sliding device 1.

Due to the relative movement in the longitudinal direction of the sliding device 1 between the upper chord 31 and the layer 58, with a corresponding load, a damping effect between them can optionally also be achieved in a direction perpendicular to the tread 23 by the damping element 50 formed by the enveloping element 46 and the filling elements 44. The degree of damping can be determined in particular by the elasticity of the packing 44.

In the jointly described FIGS. 7 to 11, further design variants of the sliding device 1 according to the invention are shown, cut in the longitudinal direction and shown in a highly simplified schematic representation. The preferably multi-layer or multi-layer structure

The sliding device 1 is formed by the covering layer 24 arranged in the outer edge zones of the sliding device 1 and forming the upper side 3 and the tread covering 25 lying opposite it and forming the tread 23. The upper side 3 of the sliding device 1 is assigned, in the binding assembly area 8, a support plate 64, which is arranged between a binding 63 and the upper side 3 of the sliding device 1, for at least one binding part 65, as shown schematically, which is connected, in particular screwed, to the sliding device 1. As shown in the following exemplary embodiments, the upper side 3 of the sliding device 1 is formed in a front partial area formed between the blade and the binding part 65 and / or in a connecting part, not shown, and the end area of the sliding device 1 opposite the blade assigned at least one stiffening and / or damping element 50 or a force and / or torque transmitting device.

As can be seen better from FIG. 7, the front and / or rear partial region of the sliding device 1 is one or in the longitudinal direction and / or in a direction crossing thereto several force-transmitting and / or torque-transmitting device 67 associated with one another in the direction of the length and / or in the direction of the width and attached to the sliding device 1 by means of fastening means 66. The devices 67 can be arranged parallel and / or inclined to one another. The force and / or torque-transmitting device 67 is formed by at least two transmission members 69 which are arranged one above the other, possibly spaced apart and overlap at least in regions in a facing end region, between which the stiffening and / or damping element 50 according to the invention is arranged. One of the transmission members 69, preferably the transmission member 69 adjacent to the upper side 3, forms an abutment 68 which is locked to the sliding device 1 by the fastening means 66. The expediently strip-shaped transmission members 69, in particular the plates 70, 71, are fastened to the sliding device 1 and / or the support plate 64 at their two opposite, opposite end regions. The device 67, in particular the transmission members 69, can be fastened using any form-fitting and / or non-positive fastening means 66 known from the prior art, in particular screws, adhesives, etc. In a covering area 72 formed by the two superimposed transmission members 69, the stiffening and / or damping elements 50 according to the invention is or are arranged between the mutually facing broad side surfaces 73 and 74 of the transmission members 69.

The broad side surfaces 73 and 74 are connected at least in regions via a filler or adhesive layer 75 to the cover element 46 filled with the fillers 44, which extends at least over a large part of a width and over a smaller region of a length of the transmission members 69. The airtight envelope element 46 filled with the filling bodies 44 is preferably provided by an elastically resettable deformable film or

Layer 47 formed, which surrounds the filler 44 on all sides. The receiving chamber 45 of the stiffening and / or damping element 50, which is enclosed on all sides by the enveloping element 46, is fluidly connected to the evacuation device 52, which is arranged, for example, on the upper side 3 of the sliding device 1. This is formed, for example, by a manually operable vacuum pump which, when actuated, pumps or sucks the air present in the receiving chamber 45 of the stiffening and / or damping element 50 and thus lowers the internal pressure present in the receiving chamber 45 to a pressure which is less than the ambient pressure. Of course, there is also the possibility that at least one of the transmission elements 69 or the abutment 68 has a manually operated backflow valve 63, via which an external vacuum pump can be connected if necessary. can be sen.

Of course, as already described in detail above and not shown further, the enveloping element 46 can, if appropriate, form in a plurality of subchambers, which may have different fillers 44, which are preferably connected to the flow via a common supply line 54 and ventilation and / or ventilation bores 51. If the receiving chamber 45 is brought into an evacuated state, the stiffening element 50, which is subjected to high tensile or compressive stress, is formed by the mutual pressing or adjoining of the filler bodies 44, which increases the hardness or the resistance to deformation of the sliding device 1.

The transmission member 69 or abutment 68 adjacent to the upper side 3 has an approximately L-shaped cross section over its longitudinal extent, so that between the upper side 3 of the sliding device 1 and the broad side surface of the longitudinal leg of the transmission member 69 facing it, even with strong bending or pressure loads formed distance is formed. The leg of the transmission member 69, which is oriented perpendicularly to the upper side 3, is equipped with a bore penetrated by the fastening means 66. The cross-sectional dimensions of the transmission members 69, hence the length, width and thickness, as well as the length, width and height of the stiffening and / or damping element 50, which corresponds approximately to the distance between the facing broad side surfaces 73, 74, can of course a wide variety of stress cases can be designed or optimized.

If the internal pressure of the receiving chambers 45 is adapted to the ambient pressure, the enveloping element 46 filled with packing elements 44 can absorb shear stresses between the transmission elements 69 arranged one above the other when a compressive or bending stress occurs. Of course, the width of the transmission members 69 can be equal to or smaller than the width of the sliding device 1. Furthermore, it is also possible to arrange a plurality of strip-shaped transmission elements 69 which are spaced apart from one another in the direction of the width of the sliding device 1 and which form the device 67 and whose width is formed by a fraction of the width of the sliding device 1.

A device 67 adjacent to the longitudinal side walls 26, 27 and a device 67 arranged between them in the region of half the width of the sliding device 1 with the stiffening or damping element 50 assigned to it on the upper side 3 is expedient attached to the sliding device 1.

Of course, the transmission elements 69 forming the support elements 76 can be formed from all possible metallic or non-metallic materials or plastics or composite materials known from the prior art, in particular sandwich components or prepregs.

FIG. 8 shows another embodiment of the arrangement of the device 67 formed by the abutment 68 and the transmission element (s) 69 with the stiffening and / or damping element 50 associated therewith, which is between the cuboid support plate 64 and a longitudinal extension thereof spaced, connected to the sliding device 1, approximately strip-shaped abutment 68 is arranged, the abutment 68 extending in the direction of the width of the sliding device 1. The one or more stiffening and / or damping elements 50 assigned to the upper side 3 of the sliding device 1 are preferably provided by the flat, airtight, elastic, filled with packing elements 44

Envelope element 46 is formed, which is equipped with one or more receiving chambers 45. Sub-areas of the enveloping element 46 are preferably connected via the enveloping or adhesive layer 75 to the mutually facing narrow side surfaces of the transmission member 69 and the support plate 64. The plate or strip-shaped transmission member 69 extending between an abutment 68 and the support plate 64 surrounds the flat envelope element 46 on all sides. The cavity formed in the evacuated state between the upper side 3 of the sliding device 1 and the flat envelope element 46 and the cavity formed between broad side surface 73 of the transmission member 69 and the enveloping element 46 can be compensated or filled by an elastically deformable layer 49 additionally arranged, for example, on the layer 47 of the enveloping element 46. A further constructive design consists in that the envelope element 46 and / or the layer 49 and / or the abutment 68 and the transmission element 69 are formed from a transparent plastic.

FIG. 9 shows a further embodiment variant of the sliding device 1 with the device 67 and with the stiffening and / or damping element 50 according to the invention assigned to it. The transmission member 69, which forms a profile-like support element 76, extends between the cuboid-shaped support plate 64 and the abutment 68, which is spaced apart from it on the upper side 3 of the sliding device 1. The longitudinal transmission member 69 preferably runs inclined to the upper side 3 of the sliding device 1, with a vertical distance between the top 3 and the transmission member 69 in the area of the support plate 64 is larger than a vertical distance in the area of the abutment 68. The approximately cuboid abutment 68 extends transversely to the longitudinal extent of the sliding device 1. One of the end areas of the support element 76 is from the support plate 64 held in position or fixed. The end region of the support element 76 opposite this end region projects into a recess 77 formed by the abutment 68, in which one or more support element 78 forming the stiffening and / or damping element 50 are arranged. A flat, in particular an approximately rectangular plate element 79 is arranged on the end face of an end region of the support element 76 facing the stiffening and / or damping element 50. The front stiffening and / or damping element 50 facing the blade is formed by an approximately cuboidal envelope element 46, on which an end face of the plate element 79 is adjacent. The end face facing the support element 76 borders or is supported on the further envelope element 46 or stiffening and / or damping element 50.

The plate element 79 divides the recess 77 into two separate chambers, in which the enveloping elements 46 or the stiffening and / or damping elements 50 are arranged, on the layer 47 of which the end faces of the plate element 79 directly adjoin. Of course, the filling bodies 44 of the two enveloping elements 46 can have different natural shadows. If necessary, the enveloping element 46 with the surface of the two

Chambers are connected in regions, in particular glued, or they are only inserted into the chambers, so that they are held exclusively over the walls of the recess or the chambers. Another embodiment is that only one of the chambers has one or more envelope elements 46.

A wall 80 of the transmission element 68 facing the narrow side surface of the support plate 64 is equipped with a guiding device 81 which pivots transversely to the longitudinal extent of the sliding device 1 and slidably supports the profile-like support element 76 for a relative displacement between the latter and the guiding device 81. The support element 76 can have a round, rectangular or square etc. cross section. The enveloping element 46, which is enclosed on all sides by the abutment 68 and possibly by cladding plates spaced apart from one another by the width of the stiffening and / or damping element 50, is connected in regions to the recess 77 via the filler or adhesive layer 75. If the receiving chamber 45 of the enveloping element 46 is evacuated, the packing 44 are pressed against each other, whereby in essentially a dimensionally stable or dimensionally stable body or the stiffening element 50 is formed. In contrast, if the receiving chamber 45 is adapted to the ambient pressure, the elastic action of the filler body 44 permits a relative adjustment of the support element 76 to the abutment 68, in which a damping effect which is dependent on the elasticity of the filler body 44 can be achieved.

10 shows a further embodiment variant of the device 67, which is arranged between the blade and the support plate 64 of the sliding device 1 and is formed by at least one abutment 68 and a plurality of transmission members 69, with the stiffening or damping element 50 according to the invention. Between the abutment which is spaced apart from the support plate 64 68, at least one further transmission element 82 is arranged in the longitudinal direction, one or more transmission elements 69 or support elements 76 extending between the transmission element 82 and the support plate 64 and the abutment 68. The approximately strip-shaped or cross-sectionally round or oval etc. abutment 68 and the approximately cuboid transmission element 82 and the support plate 64 extend over at least a large part of the width of the sliding device 1. In the recess 77 of the transmission element 82 is the support element 78 forming Stiffening and / or damping element 50 arranged. A length of the transmission member 69 is limited by the stiffening and / or damping element 50 and the narrow side surface of the support plate 64 facing it, with a length dimension of the sliding device 1 between them

Distance 83 is dimensioned smaller than a length of the transmission member 69, so that this form a curved, in particular to the top 3 of the sliding device 1 an approximately convex circular arc. The transmission element 82 connected to the cover layer 24 has on its two opposite narrow side walls facing away from one another approximately corresponding to the cross-sectional shape of the transmission element 69

Recess 84, which is penetrated by the transmission members 69 or the support members 76.

Of course, the curved transmission members 69 can generate a certain pre-tension between the stiffening and / or damping element 50 and the support plate 64 and the abutment 68, so that these are opposed by the arrangement of the end face flat plate element 79 of the two transmission members 69 facing the enveloping element 46 support the layer 47 of the enveloping element 46 or adjoin it.

The distance 83 between the envelope element 46 of the narrow side surface of the support plate 64 and the distance 83 between the envelope element 46 and the narrow side surface of the transmission element 68 facing it is expediently dimensioned the same. Of course there is also the possibility that the two distances 83 are dimensioned differently. Another embodiment variant, not shown further, consists in that the transmission element 82 arranged transversely to the longitudinal extent of the sliding device 1 is spaced apart at a distance perpendicular to the upper side 3. The distance of the transmission element 82, which is oriented perpendicularly to the top side 3, can be selected such that the transmission elements 69, which are lined up and spaced apart from one another by the stiffening and / or damping element 50, optionally form a circular arc path which is convex to the top side 3. Of course, it would also be possible in this embodiment that the enveloping element 46 is connected to a one-piece transmission element 69 in the area of the cuboid transmission element 82, so that the stiffening and / or damping element 50 within the recess 77 in the initial state permits a relative movement thereof. The transmission member 82, which is spaced apart from the support plate 64 and the abutment 68, is preferably connected to the sliding device in regions by a plurality of spaced apart support webs which are oriented perpendicular to the upper side 3. As already described in detail above, a plurality of devices 67 can be arranged parallel to one another and / or one behind the other over the width and / or length of the sliding device 1.

11 shows a further embodiment variant of the force-transmitting and / or torque-transmitting device formed by the abutment 68 and the transmission element (s) 69

67 with the stiffening and / or damping element 50 shown. The transmission member 69, which is preferably formed by two tubular, interlocking support elements 78, extends between the support plate 64 and the cuboid thrust bearing 68 distanced therefrom. The length of the two support elements 76 is smaller than that between the two narrow side surfaces of the support plate 64 and which face one another of the abutment

68 dimensioned distance 85, whereby the support elements 76 only overlap in some areas. In an end region of the transmission element 69 adjacent to the support plate 64, a preferably circular-cylindrical hollow chamber 86 is formed between the two interlocking profile-like support elements 76, in which the enveloping element 46 or the stiffening and / or damping element 50 is arranged. The outer support element 76 is preferably formed by a hollow profile, which can have a round or polygonal cross section. The internal support element 76 expediently has a full cross-section, the end region of which facing the support plate 64 is assigned to the stiffening and / or damping element 50. The cylindrical hollow adjacent to the support plate 64 chamber 86 and the annular hollow chamber 86 formed in the opposite region of the transmission member 69 is delimited by the external support element 76 and the wall of the abutment 69, in which the envelope element 46 is arranged. The stiffening and / or damping element 50 or enveloping element 46, which are filled with filling bodies 44 having the same or different properties, is arranged in the hollow chambers 86 lying on both sides opposite the end regions of the support elements 76. The support elements 76, which are held with their end regions in the support plate 64 and in the transmission member 64, are arranged at a distance from the top 3 of the sliding device 1, so that, at a predeterminable maximum bending or compressive load, the latter does not touch the top 3.

The support elements 76 are made of an elastically resettable material, which have a bending characteristic which corresponds to the bending characteristic of the sliding device 1 in the event of a tensile or compressive load. The layer 47 of the enveloping element 46 can of course at least in some areas be connected, in particular glued, to an inner surface of the support elements 76 facing the layer 47. Of course, the enveloping element 46 surrounding the surface of the hollow chamber 86 on all sides can be arranged loosely.

The receiving chambers 45 of the two opposing enveloping elements 46 can be connected to the flow via a common supply line 54, not shown, or each enveloping element 46 has its own supply line 54. In this way, for example, only one enveloping element 46 can be subjected to a vacuum, as a result of which a different hardness or deformation property can be set over several subregions of the sliding device 1.

7 to 11, it is of course possible for the transmission member 69 to be connected directly to the cover layer 24 or top side 3 of the sliding device 1 by means of a fastening device (not shown). This fastening device can be arranged at a distance from the support plate 64. The fastening device can be formed by, for example, a cuboid support element which holds the transmission element 69 or the support element 76 positioned.

For the sake of order, it should finally be pointed out that, for a better understanding of the sliding device, its components have been shown partially to scale and / or enlarged and / or reduced. The object on which the independent inventive solutions are based can be found in the description.

Above all, the individual in FIGS. 1, 2; 3; 4, 5; 6; 7, 8, 9, 10, 11 the embodiments and measures shown form the subject of independent solutions according to the invention. The relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
