By way of 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, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals and component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or merlanal combinations from the different exemplary embodiments shown and described may also represent separate, inventive or inventive solutions.

In the jointly described Figs. 1 and 2, an inventively designed or constructed sliding device 1 is shown in plan view and in section. This sliding device 1 can form a ski 2 or even a snowboard or skid, etc., depending on the selected length and width ratio. In a ski 2 is compared to a so-called snowboard above all given a greater length-width ratio.

A in top view or position of use - as shown in FIG. 1 - visible upper side 3 of the sliding device 1 is preferably profiled or contoured formed. A profiling 4 extends Optionally, the profiling 4 in a central region 7 of the slider 1 or in a binding mounting area 8 of the same leak or in the planar central region 7, which serves as a mounting platform for a corresponding bond, pass over. Starting from a possibly flat, plateau-like central region 7, the profiling 4 extends at the top 3 of the sliding device 1 in any case close to the end regions 5, 6. The profiling 4 is more pronounced in the central region 7 and in the subsequent to the binding mounting region 8 zones 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 steadily when approaching the end regions 5, 6 and finally merges into planar end regions 5, 6. In the end regions 5, 6 then at least one so-called blade of the sliding device 1 is formed.

The profiling 4 on the upper side 3 is formed by at least one, preferably two substantially mutually parallel bead-like strands 9, 10. Alternatively, it is also possible to provide three or more of such in the longitudinal direction of the slider 1 extending strands 9, 10.

Between two runs in the longitudinal direction of the slider 1 strands 9, 10 forms a more or less pronounced recess 11. The base or the bottom of the depression 11 may be substantially V-shaped or also U-shaped in cross-section, i. be formed with a largely flattened, flat sole area. Instead of a vault-like profiling 4, which 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 Profilieirangen 4. So it is e.g. also possible to flatten the bead-like strands 9, 10 in the region of the upper vertex and thereby obtain trapezoidal strands 9, 10 in cross section. Similarly, inverse embodiments with respect to the recess 11 or on the strands 9, 10 are possible, in which case in the central region of the slider 1 a beaded strand runs and both sides of the bead-like strand two groove-shaped depressions in the top 3 of the slider 1 are pronounced.

In the composite body of the sliding device 1, at least one reinforcing element 12, 13 is included. Each strand 9, 10 or each elevation 14, 15 is preferably a reinforcing element in each case 12, 13 assigned. Preferably, the reinforcing elements 12, 13 are optionally completely integrated in the sliding device 1, ie enclosed on all sides by the other components of the sliding device 1.

Optionally, it is also possible, or the reinforcing elements 12, 13, for example in the central region 7 or in the binding mounting area 8 or in the terminal zones of the binding mounting area 8 or in between the central region 7 and the end regions 5; 6 leave the area lying out of the composite body or sandwich element. For this purpose, the reinforcing elements 12, 13 run near the upper side 3 of the sliding device 1 and at least partially viewed by means of transparent portions in the form of viewing windows 16 or recesses 17 on the upper side 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, ie, a length of the reinforcing elements 12, 13 is only slightly smaller than the longitudinal extent of the profiling 4. Die Längenabmessungen der Integrated reinforcing elements 12, 13 are therefore also decisive for the longitudinal extension of the profiling 4 on the upper side 3.

The reinforcing elements 12, 13 may optionally extend 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 between the support zones 20, 21 arched upward curved.

Due to the so-called bias of the slider 1 this is not in the unloaded state or only under the influence of its own weight in the central region 7 on the ground 22. This is effected by the so-called bias height of the sliding device 1, which is defined by the largest distance between a running surface 23 of the sliding device 1 and a flat bearing surface under the influence of the weight of the slider 1.

In Fig. 2 shows a possible structure of the sliding device 1 according to the invention is shown. Out In particular, the layer structure and the cross-sectional shapes of the individual components or elements of the sliding device 1 can be seen in this cross-sectional representation.

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

Preferably, the profiled cover layer 24 is supported with its two longitudinal edges each on a steel edge 28; 29 or on an intermediate layer of high-strength material.

Between the cover layer 24 and the tread surface 25, a plurality of layers, in particular at least one lower flange 30 closest to the tread surface 25 and / or at least one upper flange 31 closest to the cover layer 24 are arranged. The lower flange 30 and / or the upper flange 31 are made of a high-strength material and are placed with reference to the cross-section of the slider 1 near the edge zones of the sliding device 1. The lower flange 30 and / or the upper flange 31 thus has u.a. by its spatial position in the slider 1 essential influence on the stiffness and flexibility of the sliding device. 1

The upper flange 31 is adhesively connected to the cover layer 24 by means of a filling or adhesive layer 32. Likewise, the mutually facing flat sides of the lower flange 30 and the tread covering 25 are adhesively connected to one another via a filling or adhesive layer 32. The lower flange 30 can, as shown schematically, extend between the sliding device 1 integrated anchoring extensions 33, 34 of the steel edges 28, 29. Alternatively, it is also possible that the lower belt 30 formed essentially as a ribbon-like, flat component extends over the anchoring extensions 33, 34 and terminates flush with the longitudinal side walls 26, 27 of the sliding device 1.

In contrast to the substantially planar design lower chord 30 of the upper flange 31 is preferably profiled. Preferably, the upper flange 31 is shaped such that it forms at least one, preferably two in the longitudinal direction extending elevations 14, 15 with an intermediate recess 11. In cross-section so that, for example, from a flat workpiece correspondingly shaped upper flange 31 is formed wave-shaped. This with respect to the cross-sectional waveform with preferably two elevations 14, 15 and the intermediate recess 11 is dimensioned such that the lower longitudinal edges 35 to 37 of the shaped Obergurts 31 are arranged at a distance 38 to the steel edges 28, 29 and the lower flange 30 can. By this distance 38 is avoided that the profiled upper flange 31 rests on the steel edges 28, 29 or on the lower flange 30.

This distance 38 is determined primarily by at least one core component 39 of the sliding device 1. This distance 38 is kept substantially constant even when force is applied to the upper side 3 and / or on the tread 23 except for relatively small permitted compression paths of the sliding device 1. The core component 39 is located between the supporting belts, in particular between the lower belt 30 and the upper belt 31. The core component 39 thus distances the lower belt 30 from the upper belt 31 and forms, together with the other layers, the entire sliding device 1 by means of intermediate filling or adhesive layers 32 a one-piece composite or sandwich element.

The remaining space around the reinforcing elements 12, 13 between the lower and upper flange 30, 31 is filled with a filler 40, preferably by 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 may also form a foam core 41 for the sliding device 1. The reinforcing elements 12, 13 and the filler 40 or the foam core 41 form the core component 39. The reinforcing elements 12, 13 may be embedded in the filler 40 or in the foam core 41. The low elasticity or flexibility of the filler 40 and the foam core 41 is chosen such that it does not break at the maximum occurring deformation of the sliding device 1 and cracking is excluded.

The one or more preferred at the apex of the arranged in approximately congruent shaped portion of the upper flange 31 reinforcing elements 12; 13 are preferred one or more at least partially covering hollow sections 42, 43 and at least one filled with packing 44 receiving chamber 45 and at least one this hermetically sealed or vacuum-tight enclosing element 46 is formed. The hollow profiles 42, 43 preferably have different cross-sectional dimensions, so that the hollow profile 42 is enveloped or surrounded by the hollow profile 43 at least in regions. The wrapping element 46 can be formed, for example, by an elastic resetting and deformable layer 47 or film. For the hollow sections 42; 43, all known from the prior art materials, such as plastics or metallic materials may be used. Preferably, the optionally made of a metallic material hollow profile 43 on an enveloping element 46 facing inner side 48 or the hollow profile 42 on a hollow profile 43 facing surface on an elastic layer 49. The hollow profiles 42, 43 define one or more stiffening and / or damping elements 50 arranged between them, which extend, for example, over a large part of the length of the sliding device 1.

Of course, it is also possible, in the longitudinal direction and / or in a direction transverse to the Gleitvorrichtun-1 between the recess 11 and the longitudinal side wall 26 or the longitudinal side wall 27 a plurality of superimposed and / or one behind the other and / or side by side and / or superimposed reinforcing elements 12th ; 13 to be arranged in the foam core 41. In the illustrated embodiment, for example, tubular hollow sections 42, 43 are provided, which have a circular cross section in a plane perpendicular to its longitudinal extent. Regarding 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 adapted to the respective cross-sectional shapes or to the profiling 4 of the top 3 of the slider 1 in the individual longitudinal sections at least approximately. The arranged in the stiffening and / or damping element 50 filler 44 form at a change in the pressure level in the receiving chamber 45 of the Hüllelementes 46 a reversible, between a first state in which it takes the form of a circular cross-section, as shown in this embodiment, and a second state by reducing, as required, an internal pressure in the enveloping element 46 below an ambient pressure - evacuation - adjustable stiffening and / or damping element 50, which in its evacuated state at least partially with the reinforcing element 12; 13 forms a positive force and / or torque transmitting transmission element. This makes it possible to increase the rigidity or the deformation resistance of the sliding device 1 in individual subareas or over large areas. A in the receiving chamber 45 of the Hüllelementes 46 projecting loading and / or venting bore 51 is fluidly connected to a removable or fixed to the slider 1, but not shown Evakuiereinrichtung 52, which pressurizes the stiffening and / or damping element 50 via an optionally manually operable vacuum pump wherein it pumps off the existing air in the receiving chamber 45 and lowers the pressure in this relative to the ambient pressure. The optionally having an elasticity filler 44 are moved towards each other by the pressurization and supported against each other and thereby form a dimensionally stable stiffening and / or damping element 50. By evacuating the receiving chamber 45 of the Hüllelementes 46 results in a slight reduction of the cross-sectional dimensions of substantially a circular ring cross-section forming stiffening and / or damping element 50, whereby a between the hollow profile 43 facing the outside of the layer 47 or foil of the enveloping element 46, a difference or a cavity between the layer 47 and the inside 48 of the hollow section 43 is formed, which of a on the hollow profile 43 arranged elastically recoverable layer 49 is filled and thereby a mutual support between the individual components is achieved. By arranging a manually operable Rückströmventiles 53 of the rigid or dimensionally stable state by ventilation, therefore, with a pressure adjustment between the receiving chamber 45 and the ambient pressure, the receiving chamber 45 of the Hüllelementes 46 with the Evakuiereinrichtung 52 can be canceled. A flow connection between the receiving chamber 45 and, for example, a vacuum pump is realized via a supply line 54. The between the underside of the upper flange 31 and at the top of the lower flange 30 optionally directly adjacent, positioned by these supported reinforcing element 12 forms with the length of the reinforcing element 12; 13 at the top and / or bottom a linear friction, whereby no additional positioning elements for the fixation of the reinforcing elements 12; 13 during the foaming process, therefore, is required in 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 made of polystyrene, etc., or through an open-cell plastic foam. The filling bodies 44 are preferably formed by a volume body, in particular in the form of a sphere or a cylinder, etc. Of course, the packing 44 may also be made from a recycled product. Suitably, the packing 44 have a core and a surrounding jacket, wherein the Core has a higher strength or lower elasticity, as this at least partially enveloping coat. In particular, the core is coated with an elastically recoverable deformable material. Of course, all other, already known from the prior art embodiments of the packing for the filling of the enveloping element 46 of the stiffening and / or damping element 50 may be used.

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

In a first condition in which ambient pressure prevails in the receiving chamber 45, stresses such as occur during driving may be partially absorbed by the damping element 50, which are transmitted to the innermost hollow profile 42 from a determinable degree of stress , As a result, a damping element 50 formed with a damping or deformation property is formed in the first state, thereby enabling a softer driving behavior. In the first state - initial state - the layer 47 of the Hüllelementes 46 adjoins the inner side 48 of the hollow section 43 or on the surface of the hollow section 42 and is at least partially on this, whereby the resilient member having a filling body 44 in case of loading a relative movement allow between the hollow section 43 and the hollow profile 42 and while driving a large or the whole share of energy is absorbed by the packing 44 and thus a damping property and a soft ride is possible. By applying a negative pressure, a mutual support of the filler body 44 is effected by the suction of the air in the receiving chamber 45 and thereby forms a reinforcing element 50 formed with a higher deformation resistance. As a result, a relative movement in the longitudinal direction of the sliding device 1 between the hollow sections 42 and 43 is prevented in the second state and effectively formed a positive connection between them, which distribute the loads or forces as they occur during travel, over the entire cross-section evenly and thereby form a high deformation resistance forming sliding device 1.

Another, not further illustrated embodiment variant is that the reinforcing element 12; 13 is arranged at least one underside or upper side of the upper flange 31 or lower flange 30 and is at least partially positioned by additional means with the lower flange 30 or upper flange 31. This becomes an illegal Slippage of the reinforcing elements 12; 13 avoided during the manufacture of the foam core 41.

As shown by dashed lines in FIG. 2, the sliding device 1 can be assigned to at least one reinforcing element 12 or 13 on each elevation 14 or 15 and / or in the recess 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 and stiffening and / or damping element 50 shown, wherein the same reference numerals have been used for previously described parts and above explanations mutatis mutandis to the same parts with the same reference numerals.

In this case, the upper of the tread 23 opposite components of the sliding device 1, unlike the previous embodiment do not extend shell-like over the core member 39, but is a relatively narrow portion of the filler 40 and the foam core 41 on the longitudinal side walls 26, 27 of the slider 1 visible. In particular, the upper components of the sliding device 1 are formed at their steel edges 28, 29 facing longitudinal edges angled flange, so that the narrow sides of these components form a portion of the longitudinal side surfaces. In this case, reinforcing elements 12; 13 in the core member 39 between the recess 11 and the longitudinal side wall 26 and / or the longitudinal side wall 27 and / or in the region of the recess 11 on the upper side 3 of the slider 1, as not further shown, are arranged. These in cross-section elliptical reinforcing elements 12; 13 and stiffening and / or damping elements 50 are integrated flat in the sliding device 1 and / or constructed on the sliding device 1. The hollow profile 42 having a circular cross-section preferably extends over a large part of the length of the sliding device 1, which at least partially extends in longitudinal extension of the hollow profile 43 in one or more sections of the sliding device 1, such as between the central region 7 and one of the end regions 5 and / or. or 6 (not shown in Fig. 3) is arranged. The outer and at least partially with the hollow profile 42 covering hollow profile 43 has in the same cross-sectional plane an elliptical or oval cross-section, one of the tip portions of the oval hollow section 43 connecting straight line is aligned substantially parallel to the tread 23 of the slider 1. The cross-sectional dimensions of the inner hollow profile 42 is compared to the cross-sectional dimensions of this At least partially surrounding hollow sections 43 made substantially smaller, so that the inner hollow section 42 is completely absorbed in cross-section and embedded all-embracing in the stiffening and / or damping element 50. The reinforcing element 12; 13 may be adjacent to the underside of the upper flange 31 and / or at the top of the lower flange 30, as shown in this embodiment.

Instead of an elliptical cross-sectional shape, it is also possible - as indicated by dashed lines - to form the outer hollow profile 43 semicircular or portal-shaped in cross-section, the curved portion facing the approximately congruently shaped upper flange 31 and the largely planar base portion facing the substantially planar lower flange 30 , The advantage of the elliptical or semicircular cross-sectional shape of the hollow section 43 or optionally of the hollow section 42 is that it can be adapted over a large peripheral region of the undulating contour of the upper flange or the upper side 3 of the sliding device 1. As a result, in the evacuated state of the receiving chamber 45 in the enveloping element 46 a wide positive engagement between the stiffening and / or damping element 50 and the hollow sections 42, 43 achieved and thereby the Gleitgeräteaufbau higher shear forces, tensile forces, bending forces or torsions withstand or absorb them.

At least one of the hollow profiles 42; 43, in particular the hollow profile 43, made of elastically recoverable deformable plastics, so that a formed between this and the stiffening and / or damping element 50 in the evacuated state cavity is formed. The enveloping element 46 or the layer 47 arranged between the hollow profiles 42 and 43 and enclosing the stiffening and / or damping element 50 in airtight manner adjoins the inner side 48 of the hollow profile 43 in the first state-initial state. Of the inner surface 48 facing surface of the hollow section 42 forms part of the Hüllelementes 46 of the stiffening and / or damping element 50. Of course, a part of the Hüllelementes 46 from the inside 48 or surface of the hollow section 42 are formed, or the sheath element 46 is formed by a layer 47 enclosed on all sides or films, which as such forms an independent component, which optionally between the hollow sections 12; 13 or directly in the core member 39 is arranged.

Another, not further illustrated variant embodiment is that the elliptical or oval cross-section having hollow sections 42, 43 with reference to the Cross-sectional shape are integrated edgewise 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 extends substantially perpendicular to the running surface 23 of the sliding device 1. The reinforcing element or elements 12 comprising the stiffening and / or damping element 50; 13 may, for example, adjoin the underside of the upper flange 31 and / or the upper side of the lower flange 30 and / or be arranged at a distance therefrom. The evacuation of the receiving chamber 45 via a formed by the hollow profile 42 supply line 54 and the loading and / or vent hole 51, whereby no additional effort for the attachment of supply lines 54 for the attachment of the negative pressure in the receiving chamber 45 are required. Of course, the hollow profiles 42 and / or 43 can have any desired cross-sectional shapes.

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 deformation resistance and can therefore be subjected to tensile and / or pressure and / or shear forces, etc. in particular.

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

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

Another, not further illustrated variant embodiment is that the stiffening and / or damping element 50 is arranged in a hollow profile 42 or hollow profile 43, the receiving chamber 45 receives the packing 44, wherein the inner surface of the Hohlprofiles 42 or the inner side 48 or inner surface of the evacuated as required wrapping element 46 and the receiving chamber 45 in the initial state adjacent to this. Of course, when using a metallic material, the inner surface or the outer surface facing away from this of the hollow section 42 may be coated with an elastically recoverable material.

In the jointly described Figs. 4 and 5, the sliding device 1 is shown in various views and in a highly simplified, schematic representation. As schematically illustrated 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 in a manner adjacent to the central region 7. In this case, 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 surface stiffening and / or damping element 50 is preferably arranged in a region closer to the upper flange 31 in the core member 39. The top flange 31 of the adjacent upper side of the Hüllelementes 46 preferably parallel to the approximately congruent shaped upper flange 31, and this oppositely arranged base member is substantially parallel to the substantially planar lower flange 30. Preferably, the distancing to the lower flange 30 stiffening and / or damping element 50 in the upper half of a half thickness 55 of the slider 1 assigned. The filled with the filler 44 sheath element 46 is preferably formed by an elastically recoverable deformable film that enclose 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 in fluid communication with the evacuation device 52 (not shown) 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 lower as the ambient pressure. By arranging a manually operable Rückströmventiles 53 in the Evakuiereinrichtung 52 this evacuated state of the stiffening and / or damping element 50 can be canceled by aeration of the receiving chamber 45. The flow connection between the Evakuiereinrichtung 52 and the receiving chamber 45 is, as shown in this embodiment, via a central loading and / or vent hole 51 and the supply line 54 given. Of course, there is also the possibility that in a transverse to the longitudinal extent of the sliding device 1 opposite arranged, separated by webs receiving chambers 45 are formed, which are optionally supplied via at least one loading and / or vent hole 51. Of course, the receiving chambers 45 can also be made by partially arranged welds.

Another embodiment is that in the receiving chamber 45 of the stiffening and / or damping element 50 at least one deformation resistance increasing hollow profile 42 is arranged, on the one hand forms a reinforcing element and on the other hand, the flow channel for the flow connection between the Evakuiereinrichtung 52 and the receiving chamber 45. Of course, the enveloping element 46 may also be surrounded by a single-part or multi-part hollow profile 46, as further illustrated, 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 has a multilayer structure and that at least one layer pointing in the direction of the Kembauteils 39 is elastically deformable, which fills a resulting evacuated cavity between the enveloping element 46 and the core member 39, whereby the individual components immediately adjacent to each other and in turn form a positive stiffening element 50.

It should be noted that in all embodiments of the evacuated state formed distance between the enveloping member 46 and the core member 39 or hollow section 42; 43 is formed essentially only by a few tenths of a millimeter.

Another, not further illustrated embodiment of a sliding device 1, in particular a snowboard, is that this in the cover layer 24 or between the cover layer 24 and a tread 25 at least one in the longitudinal direction and in a direction transverse thereto, reinforcing elements 12, 13 or a Stiffening and / or damping element 50 forms. Preferably, a plurality of spaced-apart reinforcing elements 12 are arranged transversely to the longitudinal direction of the snowboard. The longitudinally oriented reinforcing element 13 may be mounted in the same and / or in an overlying and / or underlying cross-sectional plane as the reinforcing element 12. The optionally the stiffening and / or damping element 50 having reinforcing element 12; 13 is also actuated via an Evakuiereinrichtung 52 and supply lines 54, the receiving chambers 45 are evacuated, if necessary. The function of the operation has already been described in detail previously.

Particularly advantageous in this embodiment is that 12 partially different degrees of hardness or deformation resistances can be adjusted by the plurality of transversely to the longitudinal extent of the snowboard, ski or the like arranged., Since in each receiving chamber 45 of the Hüllelementes 46 optionally different packing 44 can be introduced ,

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

As can be seen from 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 behind one another. An advantageous embodiment is at least one arrangement with one Width and a length formed planar stiffening and / or damping element 50, which extends over at least part of the length and width of the sliding device 1. ,

Of course, a plurality of planar stiffening and / or damping elements 50 can be arranged one above the other. This preferred block-shaped stiffening and / or damping element 50 is preferably made in one piece from a recoverable deformable film or layer 49, wherein the stiffening and / or damping element 50 in the longitudinal direction thereof and / or in a transverse thereto and / or in a perpendicular thereto Direction, therefore, in the direction of the thickness 55 of the sliding device 1, a plurality of separating webs separated from each other forms partial chambers. The optionally several layers 56 and 57 having stiffening and / or damping element 50 is formed in each case one enclosed by the enveloping element 46 on all sides receiving chamber 45, the receiving chambers 45 can be filled with the same and / or different properties having random packings 44. Of course, the filling element 46 can also be formed by several layers having different elasticities. Of course, a layer 56 and / or 57 can also have a plurality of receiving chambers 45.

Of course, it is also possible to distance the airtight Hüllelemente 46 to each other, so that in the core member 39 a plurality of mutually distanced Hüllelemente 46, which form required when lowering an internal pressure in the enveloping element 46 under an ambient pressure several separate dimensionally stable stiffening and / or damping elements 50.

The mutually separate enveloping elements 46 are optionally fluidly connected by two separate supply lines 54 with the Evakuiereinrichtung 52 through which the receiving chamber 45 of the enveloping elements 46 can be evacuated or subjected to negative pressure or ambient pressure. A variation of the deformation stiffness of the sliding device 1, in particular in the bending, compressive, torsional stiffness, etc., on the one hand by the height of the vacuum to be applied, influenced by the training or properties of the packing 44, so that for different applications or conditions of use different driving characteristics , in particular degrees of hardness and / or deformation properties, by the stiffening and / or damping elements 50 are adjustable.

FIG. 6 shows a further possible embodiment of the sliding device 1 according to the invention. In particular, the layer structure and the cross-sectional shapes of the individual components or elements of the sliding device 1 can be seen from this cross-sectional representation.

The outer marginal zones of the sliding device 1 are, as is known per se, formed by a cover layer 24 forming the upper side 3 and a running surface 23 arranged opposite to this, which forms the tread covering 25. The approximately planar covering layer 24 forms the upper side 3 and possibly also the longitudinal side surfaces 26 and 27 of the sliding device 1 oriented perpendicularly on the running surface 23. Steel edges 28, 29 represent a lateral boundary of the tread 23. Between the cover layer 24 and the tread 25 are several layers or inserts or layers, in particular at least one lying in the tread 25 lower chord 30 and / or at least one of the top layer 24 nearest upper chord 31, which is connected in each case via a filling or adhesive layer 32 with this. Between the upper flange 31 and the lower flange 30, further layers 58, 59 are preferably formed, which essentially form the core component 39. The core component 39 consists of a plurality of schematically indicated, glued together and compressed bars 60 made of wood. The individual strips 60 are connected to one another via filling or adhesive layers 32 or glue layers or synthetic resins. Of course, it is also possible that the core member 39 may consist of a sandwich component, for example consisting of different types of plastic foams or a corresponding aluminum construction or the like.

The upper flange 31 points in the direction of the longitudinal extent of the sliding device 1 and in the direction the tread 23 at least one, preferably a plurality of transverse to the longitudinal direction of the slider 1 from each other, in cross-section approximately trapezoidal projections 61, each projecting into a formed by the layer 58 or 59, in the direction of the tread 23 aligned reset 62. Of course, the extensions 61 and resets 62 may have any cross-sectional shapes, such as rectangular, triangular, etc., in cross-sectional shapes. The layer 58 may be formed from any of the materials known in the art such as, for example, plastics, glass fiber reinforced plastics, composite plastics or metallic plastics, particularly aluminum, titanium, or corresponding metal alloys or knits or fabrics. Of course, it is also possible that between the upper flange 31 and the layers 58, 59, only one extension 61 and a corresponding with this reset 62 is arranged. A perpendicular dimensioned between the side edges of the upper flange 31 and the layer 58 serves to receive at least one arranged between these stiffening and / or damping element 50, wherein the top flange 31 facing surface of the layer 58 or the cover layer 24 facing away from the upper surface 31 forms a part of the receiving chamber 45 bounding vacuum-tight enveloping element 46.

In this receiving chamber 45 protrudes at least one, as not further illustrated, loading and / or vent hole 51 and supply line 54, which is fluidly connected to the Evakuiereinrichtung 52.

As shown in FIG. 6 further, the second evacuated state is shown schematically and greatly simplified. The formed in the evacuated state, greatly enlarged cavity between the casing element 46 and the surface of the upper flange 31 is filled for example by a coating of the upper flange 31 or by an independent, elastically recoverable deformable layer, so that between the upper flange 31 and the layer 58 a form-fitting Stiffening element 50 is formed.

The top flange 31 can be formed, for example, from a coated Alupreßteil or an Alugußteil or a corresponding hard aluminum or steel insert, wherein the coating is formed of an elastically recoverable deformable material. But it is of course also possible that the top flange 31 or the envelope member 46 is formed multi-layer and forms its own high-strength elastically deformable plastic part.

There is thus no or only a slight relative movement between the upper flange 31 and the layer 58 allows.

If the internal pressure in the enveloping element 46 is adapted to the ambient pressure, the slight distance or cavity between the enveloping element 46 of the stiffening and / or damping element 50 and the surface of the upper flange 31 of the elastic layer 58 of the upper flange 31 will be removed from the recovering enveloping element 46 formed.

In this case, relative movements between the upper flange 31 and the layer 58 or the layer 59 are caused by an incoming load, as occurs during the journey. As a result, a smooth driving behavior with the sliding device 1 can be made possible.

Due to the relative movement in the longitudinal direction of the sliding device 1 between the upper flange 31 and the layer 58, a damping effect between these can be achieved by the damping element 50 formed by the enveloping element 46 and the packing members 44, if appropriate, also in a direction perpendicular to the running surface 23. 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 embodiments of the sliding device 1 according to the invention, cut in the longitudinal direction and in a greatly simplified schematic representation shown. The preferably multi-layered or multi-layered sliding device 1 is formed by the arranged in the outer edges of the sliding device 1, the upper side 3 forming cover layer 24 and the opposite thereto, the tread 23 forming tread 25. The upper side 3 of the sliding device 1 is in the binding mounting region 8 a between a binding 63 and the top 3 of the slider 1 arranged support plate 64 for at least one binding member 65, as shown schematically, associated with the sliding device 1, in particular screwed. As shown in the following embodiments, the upper side 3 of the sliding device 1 is formed in a front portion formed between the blade and the binding portion 65 and / or in a rear portion formed between another binding portion not shown and the blade opposite end portion of the slider 1 at least one stiffening and / or damping element 50 or a force and / or torque-transmitting device assigned.

As can be seen more clearly from FIG. 7, the front and / or rear portion of the sliding device 1 is in the longitudinal direction and / or in a direction transverse thereto a plurality of spaced apart in the direction of the length and / or in the width direction and attached via fastening means 66 to the sliding device 1 attached force and / or torque-transmitting device 67. The devices 67 can be arranged parallel and / or inclined to each other. The force and / or torque-transmitting device 67 is formed by at least two superimposed, possibly spaced apart and at least partially covering in a mutually facing end portion transfer organs 69, between which the stiffening and / or damping element 50 according to the invention is arranged. One of the transmission elements 69, preferably the transmission element 69 adjacent to the upper side 3, forms an abutment 68 which is locked to the sliding device 1 by means of the fastening means 66. The appropriately 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 end regions facing away from one another. The attachment of the device 67, in particular the transmission members 69, can be done with all known from the prior art positive and / or non-positive fastening means 66, in particular screws, adhesives, etc. In a cover region 72 formed by the two transfer elements 69 arranged one above the other, the stiffening and / or damping elements 50 according to the invention are or are arranged between the mutually facing broad side surfaces 73 and 74 of the transfer elements 69.

The broad side surfaces 73 and 74 are at least partially connected via a filling or adhesive layer 75 with the filling element 44 filled with the enveloping element 46, which extends at least over a large part of a width and over a smaller portion of a length of the transmission members 69. The filled with the packing 44 airtight wrapping element 46 is preferably formed by an elastically recoverable deformable film or layer 47, which encloses the packing 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 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 lower as the ambient pressure. Of course, there is also the possibility that at least one of the transmission members 69 and the abutment 68 has a manually operable return valve 63, via which, if necessary, connected an external vacuum pump can be.

Of course, as previously described in detail and not further illustrated, the sheath element 46 can optionally form a plurality of subchambers, which optionally have different random packings 44, which are preferably flow-connected via a common supply line 54 and loading and / or venting bores 51. If the receiving chamber 45 is brought into an evacuated state, the stiffening element 50, which is to be loaded to a high tension or pressure, is formed by the mutual pressing or adjoining of the filling bodies 44 within the enveloping element 46, which increases the hardness or the deformation resistance of the sliding device 1.

The upper side 3 adjacent transfer member 69 and abutment 68 has a longitudinal extent about L-shaped cross-section, so that between the top 3 of the slider 1 and the facing this broad side surface of the longitudinal leg of the transmission member 69, even with strong bending or compressive loads formed distance is formed. The aligned perpendicular to the top 3 leg of the transmission member 69 is equipped with a projected through the fastening means 66 bore. The cross-sectional dimensions of the transmission members 69, therefore, 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, of course, to a variety of stress cases be designed or optimized.

If the internal pressure of the receiving chambers 45 adapted to the ambient pressure, so filled with packing 44 sheath element 46 can absorb shear stresses between the superimposed transmission members 69 at a pressure or bending stress occurring. Of course, the width of the transfer members 69 may be set equal to or less than the width of the slider 1. Furthermore, it is also possible that a plurality of spaced apart in the width direction of the slider 1 from each other strip-shaped, superimposed, the device 67 forming transmission members 69 are arranged, the width of which is formed by a fraction of the width of the slider 1.

It is expedient in each case one 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 on the upper side 3 associated therewith the sliding device 1 attached.

Of course, the support members 76 forming transmission members 69 may be formed of any known in the prior art metallic or non-metallic materials or plastics or composites, 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 69 with the stiffening and / or damping element 50 associated therewith, and between the parallelepiped-shaped support plate 64 and one of these in longitudinal extension arranged distanced, connected to the slider 1, approximately strip-shaped abutment 68 is arranged, wherein the abutment 68 extends in the width direction of the slider 1. The one or more of the top 3 of the slider 1 associated stiffening and / or damping elements 50 are preferably formed by the filled with packing 44 planar, airtight elastic sheath member 46 which is equipped with one or more receiving chambers 45. Subregions 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 element 69 and the support plate 64. The plate-shaped or strip-shaped transfer element 69 extending between an abutment 68 and the support plate 64 encloses the flat enveloping element 46 on all sides. The hollow space formed in the evacuated state between the upper side 3 of the sliding device 1 and the flat enveloping element 46 and the cavity formed between the broadside surface 73 the transfer element 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. Another structural design is that the enveloping element 46 and / or the layer 49 and / or the abutment 68 and the transmission element 69 are formed of 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 associated therewith. Between the parallelepiped-shaped support plate 64 and the abutment 68 locked to the upper side 3 of the sliding device 1, the transmission element 69 forming a profile-like support element 76 extends. The longitudinal transmission element 69 preferably extends inclined to the upper side 3 of the sliding device 1, wherein a vertical distance between the top 3 and the transfer member 69 in the region of the support plate 64 is sized larger than a vertical distance in the region of the abutment 68. The approximately rectangular abutment 68 extends transversely to the longitudinal extent of the slider 1. One of the end portions of the support member 76 is of the support plate 64 is kept positioned 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 elements 78 forming the stiffening and / or damping element 50 are arranged. At a stiffening and / or damping element 50 facing end portion of the support member 76 a flat, in particular an approximately rectangular plate member 79 is arranged end face. In this case, the blade facing the front stiffening and / or damping element 50 is formed by an approximately cuboid Hüllelement 46, on which an end face of the plate member 79 is adjacent. The end face facing the support element 76 adjoins or is supported on the further enveloping element 46 or stiffening and / or damping element 50.

The plate member 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 whose layer 47 the end faces of the plate element 79 directly adjoin. Of course, the filling bodies 44 of the two enveloping elements 46 may have different properties. Optionally, the sheath 46 may be partially connected to the surface of the two chambers, in particular glued, or they are inserted only in the chambers, whereby the holder thereof is carried out exclusively on the walls of the recess or the chambers. Another embodiment is that only one of the chambers has one or more enveloping elements 46.

One of the narrow side surface of the support plate 64 facing wall 80 of the transfer member 68 is equipped with a pivoting transversely to the longitudinal extension of the slider 1 receiving guide device 81 which supports the profile-like support member 76 for a relative displacement between this and the guide device 81 slidably. The support member 76 may have a round, rectangular or square, etc. cross-section. The enveloping element 46, which is surrounded on all sides by the abutment 68 and possibly by the width of the stiffening and / or damping element 50, is partially connected to the recess 77 via the filling or adhesive layer 75. If the receiving chamber 45 of the enveloping element 46 evacuated, the filling body 44 are pressed against each other, whereby in essentially a dimensionally stable or dimensionally stable body or the stiffening element 50 is formed. If, in contrast, the receiving chamber 45 adapted to the ambient pressure, a relative displacement of the support member 76 is allowed to the abutment 68 by the elastic effect of the filler 44, in which a dependent of the elasticity of the filler 44 damping effect can be achieved.

10 shows a further embodiment variant of the device 67 which is arranged between the blade and the carrier plate 64 of the sliding device 1 and is formed by at least one abutment 68 and several transmission elements 69 with the stiffening or damping element 50 according to the invention. Between the abutment distanced from the carrier plate 64 68, at least one further transmission element 82 is arranged in the longitudinal extent, wherein one or more transmission elements 69 or support elements 76 extend between the transmission element 82 and the support plate 64 and the abutment 68. Expediently, the approximately strip-shaped or round or oval cross-section etc. abutment 68 and the approximately cuboid transfer member 82 and the support plate 64 extends over at least a large part of the width of the slider 1. In the recess 77 of the transfer member 82 which is the support member 78 forming Stiffening and / or damping element 50 is 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, wherein a dimensioned between them in the longitudinal extension of the slider 1 distance 83 is smaller than a length of the transmission member 69, so that this one curved, in particular to the top 3 of the sliding device 1 form an approximately convex circular arc path. The transmission member 82 connected to the cover layer 24 has, at its two opposite, narrow side walls facing away from one another, a recess 84 which corresponds approximately to the cross-sectional shape of the transmission member 69 and which is penetrated by the transmission members 69 and the support members 76.

Of course, the curved transmission members 69 can produce a certain bias between the stiffening and / or damping element 50 and the support plate 64 and the abutment 68, so that this by the arrangement of the enveloping element 46 facing end face plate member 79 of the two transmission members 69 against the layer Support 47 of the enveloping element 46 and adjoin them.

The distance 83 between the envelope member 46 of the narrow side surface of the support plate 64 and the distance 83 between the enveloping element 46 and the narrow side surface of the transmission element 68 facing the latter is expediently the same. Of course, there is also the possibility that the two distances 83 are dimensioned differently. Another, not further illustrated embodiment variant is that the transversely arranged to Längserstrekkung the slider 1 transfer member 82 is arranged in a distance perpendicular to the top 3 dimensioned distance. The aligned perpendicular to the top 3 distance of the transfer member 82 may be selected such that the juxtaposed, spaced apart to the stiffening and / or damping element 50 transmission members 69 optionally form a convex to the top 3 circular arc. Of course, it would also be possible in this embodiment, that the enveloping element 46 is connected to a one-piece transmission member 69 in the region of the cuboid transfer member 82, so that the stiffening and / or damping element 50 within the recess 77 in the initial state permits a relative movement. The spaced apart from the support plate 64 and the abutment 68 transmission member 82 is preferably partially connected by a plurality of spaced apart and perpendicular to the top 3 aligned support webs with the sliding device. As already described in detail above, a plurality of devices 67 can be arranged across the width and / or length of the sliding device 1 parallel to one another and / or one behind the other.

FIG. 11 shows a further embodiment variant of the force-transmitting and / or torque-transmitting device 67 formed by the abutment 68 and the transmission element or elements 69 with the stiffening and / or damping element 50. The preferably formed by two tubular intermeshing support members 78 formed transfer member 69 extends between the support plate 64 and the spaced therefrom rectangular abutment 68. A length of the two support members 76 is smaller than a dimension between the two facing each other narrow side surfaces of the support plate 64 and the abutment 68 dimensioned distance 85, whereby the support members 76 only partially overlap. In one of the support plate 64 adjacent end portion of the transfer element 69 is formed between the two interlocking profile-like support members 76 a preferably circular cylindrical hollow chamber 86, in which the enveloping element 46 and the stiffening and / or damping element 50 is arranged. Preferably, the outer support member 76 is formed by a hollow profile, which may have a round or polygonal cross-section. The inner support element 76 expediently has a solid cross-section, the end region of the support plate 64 facing the stiffening and / or damping element 50 is assigned. The support plate 64 adjacent cylindrical hollow chamber 86 and this formed in the opposite region of the transmission member 69 annular hollow chamber 86 is limited by the outer support member 76 and the wall of the abutment 69, in which the enveloping element 46 is arranged. In the end regions of the support elements 76 on both sides opposite hollow chambers 86, the stiffening and / or damping element 50 or shell member 46 is arranged, which are filled with the same or different properties having random packings 44. The support elements 76 fixed with their end regions in the support plate 64 and in the transfer element 64 are arranged at a distance from the upper side 3 of the sliding device 1, so that the upper side 3 does not touch them at a predeterminable maximum bending or compression load.

The support members 76 are made of an elastically recoverable material having a bending characteristic which corresponds to the bending characteristic of the slider 1 in the case of a tensile or compressive load. Of course, the layer 47 of the enveloping element 46 can be connected, in particular adhesively bonded, to an inner surface of the supporting elements 76 facing the layer 47 at least in regions. Of course, in the surface of the hollow chamber 86 on all sides bounding enveloping element 46 can be arranged loosely.

The receiving chambers 45 of the two opposite enveloping elements 46 may be flow connected via a common, not further shown supply line 54, or it has 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, whereby a different hardening or deformation property can be set over a plurality of subregions of the sliding device 1.

Of course, it is possible in all embodiments in FIGS. 7 to 11 that the transmission element 69 is connected directly to the cover layer 24 or upper side 3 of the sliding device 1 via a fastening device, not shown further. This fastening device can be arranged at a distance from the support plate 64. The fastening device can be formed by a, for example, cuboidal support element, which supports the transmission element 69 or the support element 76 in a positioned manner.

For the sake of order, it should finally be pointed out that, for better understanding of the sliding device, its components have been shown partly unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.

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