Description

The invention relates to a board-like gliding device, in particular to a ski or a snowboard as described in claim 1.

DE 39 25 491 A1 describes a ski with a plate arrangement integrated in the ski body, comprising at least one holding plate for fixing ski binding parts on the ski body, described. This holding plate, which is fully integrated in the ski body, extends in the longitudinal direction of the ski within the usual bond area, i.e. not much further than above the screw-in points in question for the binding. This is intended to be be that this holding plate has as little interference as possible on the other parts or takes on the flexibility values of the ski. This holding plate in which the fastening screws for the ski binding parts to get the most hold, is interposed an elastomer layer in a recess on the top of a conventional one Wood core of the ski body arranged. At the top of the holding plate is inside the Core recess also arranged an elastomer layer. The two thin layers of elastomer cover as completely as possible the top and bottom of the holding plate and extend only slightly beyond the front ends of the holding plate in the longitudinal direction of the ski. There is a general one above the top elastomer layer and below the wooden core usual metallic layer, in particular a thin aluminum plate arranged, which the Ski construction reinforced. In addition, this multilayer structure is known in the way provide a top layer on the sides and on the top and on the bottom a tread covering ensuring good sliding properties is arranged. So that in holding plate to be integrated into the ski body has as little influence as possible on the flexibility values of the ski, it is suggested to make them as short and thin as possible, which is the maximum achievable holding force for the ski binding parts on the ski body is impaired. In addition, the holding plate and the elastomer layers are due to the arrangement Near the upper edge of the ski superstructure, relatively high mechanical point loads and exposed to compressive or tensile stresses which, in extreme cases, lead to lifting the binding holder can lead to the ski surface after the small surface Holding plates arranged in the upper zones of the ski superstructure Load layers in a relatively small area and try to lift these layers or to impose it in the vertical direction. In addition, the elastomer layers Intended function of a compensation element for length shifts Ski deflections cannot be achieved because the fastening screws for the ski binding parts due to the relatively large thickness dimension compared to the top layers of the core will inevitably also occur in the core and thereby relative shifts prevented between the holding plates and the ski in the longitudinal direction of the ski are.

EP 0 474 967 A2 and US 5,016,901 A describe board-like sliding devices, in particular Sheer, with container or trough-like anchoring parts for fastening screws one Ski binding. These anchoring parts are in groove-shaped recesses in the Arranged rigidly fixed Schikerns. The multi-trained anchoring elements are arranged directly below the top flange of the ski superstructure. The stripe-shaped on both sides of the longitudinal central axis of the ski Anchoring elements have a length that is shorter than a cheek body Ski binding is. The anchoring elements comprise layers of elastomeric material and at least one other layer of hard material, for example of metal, into which the fastening screws for the ski binding are anchored. There are also spacers provided for distancing the ski binding or its base plate from the top of the ski. With this construction, there is an elastic mounting of the ski binding enables the ski, the power transmission between the ski binding and the ski takes place however, in a relatively restricted area below the ski binding, which makes the Distribution of forces within the glider is not absolutely satisfactory.

US 5,944,335 A discloses a board-like gliding device, in particular a ski, with a Supporting structure and a core which is at least essentially rigidly connected to it. In A longitudinal middle section of the glider is above the core in the longitudinal direction of the glider, at least over the binding area, elastically supported, cup-shaped binding carrier formed. This binding carrier is a rigid shell carrier trained and encompasses the core integrated in the glider structure at its Side surfaces, the shell support being supported elastically. With this structure the distribution of forces in the longitudinal direction of the glider is somewhat improved, at the same time, however, the bending stiffness of the glider in the section with the rigid, peripherally located shell carrier noticeably increased.

The present invention has for its object in a board-like glider to create a high-strength anchoring option for binding parts, the selective peak loads avoids individual components of the glider and at the same time the actually opposite ones Requirement for a binding holder that is as separate as possible from the construction of the glider justice.

This object of the invention is achieved by the features according to claim 1.

The advantage resulting from the features of the characterizing part of claim 1 in that a mountable mount on the glider according to the invention for mounting of a user's shoe, is supported starting from the core zone of the glider and that the binding support is almost entirely limited to the core zone of the glider. On the one hand, this creates a very high holding torque for the binding parts on Glider reached. In particular, the relatively high remaining layer thickness above of the core member holding a bond, lifting or even delamination the layers or layers arranged above the core component are effectively counteracted. The fact that the binding absorption or the binding holder on the core zone of the glider is concentrated, the sandwich structure will also be a supporting function showing outer layers or edge zones from the binding holder influenced, especially hardly weakened. In addition, these outer layers or Edge zones are no longer clamped to the core component by the binding part to be assembled, but is a direct means of load transfer due to the extensions or the spacer elements between the binding to be assembled and the inside or embedded Core component and vice versa created. After the core component is almost over The entire length of the glider extends to that of a binding part forces and loads acting on the core component inside the composite element widely distributed, so that peak loads of individuals originating from a ski binding part Parts of the glider will no longer occur selectively. A major advantage The training according to the invention is also that the bond by the elastic Layer is nevertheless decoupled to a certain extent from the glider structure, so that on the Impacts or vibrations of the glider only in damped form be transferred to the binding and thus to the foot of the user. The quasi floating Storage of the core component in the center area of the glider also results in the best chassis-like damping properties.

Due to the configuration according to claim 2 can be mounted on the glider Binding part of a two-part binding unit preferably consisting of front and heel cheeks directly or rigidly on the core component elastically integrated in the glider body support. It is essential that between the core component receiving the binding and no relative shifts can occur in the corresponding binding part, after the core extensions or independent spacer elements a high pressure rigidity exhibit.

The features according to claim 3 allow damping of impulses on the tread of the glider impact or vibration, so that the foot the user's peak loads are reduced, resulting in fatigue-free Using the glider over a longer period of time results.

Scratch or shear marks between the two real moving parts, which longer term The design could block the relative adjustability reliably designed according to claim 4.

A reliable structure to achieve a sufficient relative adjustability between the two core components, which also has good mechanical cohesion ensures the individual parts is achieved by the features according to claim 5.

The embodiment according to claim 6 enables relative adjustability of the individual Core components, whereby a defined initial or the rest position of individual core components is secured.

According to the embodiment according to claim 7, commercially available elements can be used as the core component can be used for the glider, reducing the production costs for such a glider can be kept low.

An optimal mean between high strength and lightweight construction can be according to the Features can be achieved in claim 8.

It is advantageous if the first core component and / or the entire core element is embedded in a relatively elastic foam core with a density of 200 kg / m ³ to 400 kg / m ³ . Such a foam plastic for creating an elastic embedding for the complete core element or for the core element responsible for the binding holder enables problem-free and inexpensive manufacture of the gliding device.

The embodiment according to claim 10 or 11 ensures a precise and delay-free Control of the glider according to the effects of the user on the glider Control forces.

Due to the configuration according to claim 12 tensions between the top of the glider and a binding part or a binding plate avoided as far as possible, whereby the glider largely retains the planned flexibility values even after mounting the binding maintains.

Establish tension between the extensions or spacer elements and the latter Layers or layers of the gliding device are further developed according to claim 13 or 14 switched off, creating a harmonious curve of the bending curve of the glider is achieved.

The embodiment according to claim 15 prevents the ingress of moisture or Foreign bodies such as Ice or snow in the interior of the glider, so that functional impairments or damage to the same can be excluded.

Dynamic design characteristics of the glider are determined by the design variant Claim 16 guaranteed.

The gliding device according to the invention can be configured according to claim 17 or 18 can be produced as simply as possible and the desired effects can also be achieved.

The measures according to claim 19, even in the event of extreme deflection, of the recessed Core component has a high breaking limit of the same. It will also be more beneficial Way relative shifts between the two core components in the longitudinal direction of the glider excluded.

By integrating several separate core elements in the glider, their mechanical Properties or strength values are specifically adapted to the requirements. So it is e.g. possible, the inner core elements related to a pair of skis assign a different characteristic than the external core elements of the left and right ski of existing pair of skis.

A highly effective decoupling of the binding parts from the actual gliding device is achieved by the embodiment achieved according to claim 21. The natural flexibility of the glider also affected as little as possible in its binding assembly area. Also achieved such a glider chassis-like driving characteristics.

The embodiment according to claim 22 advantageously enables integration of core elements with relatively large cross-sectional dimensions, whereby the desired Characteristic of the core element to be integrated can be easily achieved. Furthermore, can achieve optimal properties from the core elements over comparatively wide areas be ensured.

Finally, an embodiment according to claim 23 is advantageous because it makes one possible direct power transmission from a core component mounted on the lower flange and / or from a bowl - shaped cover layer or from your own side panels on the steel edges and vice versa is achieved, which results in optimal control behavior.

The invention is described below with reference to the exemplary embodiments shown in the drawings explained in more detail.

The location information selected in the description, e.g. up down, laterally, etc. related to the figure immediately described and shown and are in the event of a change in position, to be transferred accordingly to the new position. Furthermore, also Individual features or combinations of features from the different shown and described Exemplary embodiments for themselves, inventive or inventive Represent solutions.

1 to 4 is a construction possibility of an inventive according to various representations Illustrated glider 1. The board-like gliding device according to the invention 1 is in particular formed by a ski 2 for performing alpine skiing. Alternatively for this purpose, the glider 1 can also be designed as a snowboard after the primary differences are only in the length to width ratio of the gliding devices 1.

The sliding device 1 consists of several, at least in certain areas, non-positively with one another connected layers or layers, the underside or a sliding surface 3 of the gliding device 1 due to good sliding properties tread 4 and a Top 5 of the gliding device 1 is formed by a cover layer 6. Lower longitudinal side edges of the gliding device 1 are formed in the usual manner from steel edges 7, 8 and limit the tread surface 4. The cover layer 6 covers at least the top one Location of the gliding device constructed as a sandwich or composite element 1. According to the illustration In Fig. 3, the cover layer 6 can also over the longitudinal side walls 9, 10 of the Extend sliding device 1 or form side cheeks 11, 12 of the sliding device 1. In this Case thus extends a one-piece cover layer 6 shell-like over the top layer and also forms the outer longitudinal side surfaces of the gliding device 1.

The sliding device 1 comprises at least one lower flange closest to the tread surface 4 13 and / or an upper chord 14 closest to the cover layer 6 made of high-strength material. The lower flange 13 and the mostly also existing upper flange 14 are flat or through thin layers of metallic materials profiled transversely to its longitudinal direction and / or formed from fiber-reinforced plastics or synthetic resins. Especially at The use of plastic straps is made possible by using synthetic resin, usually epoxy resin, impregnated fiberglass fabric formed, the final curing of these straps under pressure and temperature when pressing the individual layers of the ski. such Belts are commonly referred to as prepregs. The metallic materials a lower or upper flange 13, 14 are usually made of aluminum or by a high-strength and light aluminum or titanium alloy.

Referring to its cross section, the can be continuous over the entire length of the Gliding device 1 extending, strip or band-like lower flange 13 also close above the Steel edges 7, 8 run and are flush with the outer longitudinal side surfaces of the steel edges 7, 8 complete and so for better power transmission between a bowl-shaped Cover layer 6 and the steel edges 7, 8 contribute. The side cheeks 11, 12 of the bowl-shaped Covering layer 6 is then supported accordingly over the intermediate layer wide dimensioned lower flange 13 directly on the top of the steel edges 7, 8.

The underside of the cover layer 6 usually carries the optical appearance of the gliding device 1 determining design layer and can therefore also be called top or design layer become.

In particular, the strip-like or belt-like upper chord 14 lying below the cover layer 6 can also be profiled. In particular, the cross-sectional shape of the upper chord 14 at least approximately to the profiling of the surface or top side 5 of the gliding device 1 be adjusted. In the embodiment shown, the top chord 14 essentially has one U-shaped cross-section, with its two legs extending only over a partial area extend an overall height of the glider 1.

At least one core component 15 is arranged between the lower flange 13 and the upper flange 14. This core component is arranged in the middle or in the center of the gliding device 1, whereas the surrounding layers and layers, in particular the lower flange 13 and the Upper chord 14, lie in the edge zones of the gliding device 1. The core member 15 takes over it also a comparatively large part of the cross-sectional area of the gliding device 1. In front The height dimension is all in the intended binding assembly area of the gliding device 1 of the core component 15 more than 50% of the cross-sectional height of the gliding device 1. The core component 15 therefore virtually holds the upper layers of the gliding device 1, in particular the upper chord 14, at a distance from the layers below, in particular from the lower flange 13.

In the embodiment shown, the core component 15 is made of wood. In the shown In the exemplary embodiment, the core component 15 consists of several, in particular connected glued together slats 16 made of suitable wood. The slats 16 of the wooden core component 15 are in the transverse direction of the sliding device 1 with edged Alignment aligned, with a slat width 17 vertical to the sliding surface 3 of the Gliding device 1 runs and a lamella thickness 18 parallel to the sliding surface 3 and transverse to Longitudinal direction of the glider 1 is measured. The slat width 17 is one Multiple of the slat thickness 18.

At least one underside 19 of the core component 15 rests on an elastic layer 20 in the Interior of the gliding device 1. The elastic layer 20 can be an elastomeric Plastic and / or by a foam plastic with appropriate spring-elastic properties be educated. The elastomer layer or the elastic layer 20 can have rubber-like or foam-like properties and should be among those acting Forces are resilient and automatically resettable due to their inherent elasticity his. The elastic layer 20 can by vulcanization or by foaming the underside 19 of the core component 15 is integrally formed or else onto an underlying one Position, in particular on the lower flange 13, are applied. Of course it is too possible, the elastic layer 20 as a separate layer in the manner of an intermediate layer in the Integrate glider or core structure.

By supporting the core component 15 on the elastic layer 20, this is opposite the surrounding layers and layers in the vertical direction to the sliding surface 3 or to the top 5 of the glider 1 at least slightly displaceable, if appropriate on the latter apply high forces. The core component is then shifted in the force-free idle state 15 automatically again in the starting or rest position shown in Fig. 3.

In particular, one to be mounted on the sliding device 1 is supported for the sake of simplicity Binding part, not shown, for holding at least one end region of a shoe of a user directly on this core component elastically mounted in the body of the gliding device 1 15 from.

The corresponding binding part can be pressure-resistant extensions 21 or alternatively via rigid spacers 22 directly on a hard, unyielding top 23 of the Support core component 15.

In the exemplary embodiment according to FIG. 3, the compression-resistant extensions 21 of the core component 15 formed by separate spacer elements 22, which are located directly on the top 23 of the Support the core component and are rigidly and unrelentingly connected to the latter. The one usual binding assembly area or placed in the center area of the glider 1 Extensions 21 or spacer elements 22 of the core component 15 pass through the upper chord 14 completely and the overlying cover layer 6 at least for the most part and close approximately flush with the top 5 of the glider 1.

The extensions or spacer elements 22 represent rigid load transfer or pressure transmission elements to be mounted between the elastically mounted core component 15 and one Binding part.

It is essential that the extensions 21 and spacers 22 of the core component 15 overlying layers, in particular the top chord 14, and the cover layer 6 with sufficient Penetrate play and find their hold only on the core component 15.

As can best be seen from FIG. 3, the pressure-resistant extensions 21 or spacer elements 22 on the top 23 of the core component 15 by its own, preferably metallic elements formed, which is firmly connected to the core component 15, in particular to the core component 15 are screwed. With the part representing a spacer 24 protrude Extensions 21 or spacer elements 22, starting from the core area of the gliding device 1, in Vertical direction to the sliding surface 3 to the outermost cover layer 6 before or close the Extensions 21 of the core component 15 at least flush with the cover layer 6. That in the Core member 15 screwed or otherwise connected to the core member 15 spacer 22 also serves as a receptacle for schematically indicated fastening screws 25 a binding part and / or a. serving to increase the footprint, generally known Binding plate. Such a binding plate is between the gliding device 1 and to arrange the underside of the binding part to be assembled. The extensions 21 or Spacer elements 22 therefore provide a direct, rigid coupling between the core component 15 and the corresponding binding part and / or the corresponding binding plate. The Binding or the underlying binding plate is from the other layers and Layers of the glider 1 largely decoupled and exclusively floating on the in the glider structure integrated core component 15 stored and connected to this. The binding parts of a preferably two-part safety ski binding are thereby no longer clamped or jammed with the top 5 of the gliding device 1, but can detached from the surface or the cover layer 6 via the extensions 21 or spacer elements 22 directly and at least predominantly or solely on the central part of the glider body arranged core component 15 sit.

The core component 15 responsible for the binding support or binding holder can represent a first component of a multi-part core element 26 of the gliding device. In particular In addition to the first core component 15 holding the binding, another core component can be used 27 be formed. This additional core component 27 takes the first one for Binding holder provided core component 15 at least partially or is the first Core component 15 is at least partially delimited by second core component 27. How in particular 3, the further core component 27 can be the first core component 15 on the latter Delimit top side 23 and on its longitudinal side surfaces 28, 29. The core element 26 forming core components 15 and 27 are movably connected to each other, the maximum relative adjustment between the two core components 15 and 27 compared to whose dimensions are relatively small. Under no circumstances will the individual Core components 15, 27 rigidly glued, screwed or positively interconnected, but is between the core member 15 and the core member 27 a limited relative displacement allowed.

If necessary, the second or the outer core component 27 forms a type of linear guide 30 for the first or inner core component 15. The quasi core-bearing binding part can therefore over this linear guide 30 with deformation of the elastic layer 20 are adjusted predominantly in the vertical direction to the sliding surface 3 of the gliding device 1, provided that Appropriate high forces act on the elastic layer 20 via the core component 15. The absolutely limited and relatively limited adjustment movement of a binding part in the vertical direction to the sliding surface 3 is forcibly coupled with the adjustment movement of the first core component 15.

This linear guide 30 can be constructed in that the second core component 27 is hood-like extends over the inner core member 15 and largely without play to the Longitudinal side surfaces 28, 29 of the wooden core component 15 abut. The relative adjustability between the outer core member 27 and the inner core member 15 is exclusively the resistance to deformation or the modulus of elasticity of the elastic layer 20 determined.

The outer core component 27 is in the embodiment according to FIG essentially U-shaped, i.e. by a protruding from a base plate with an angular distance from it Legs 31, 32 produced shape profile 33 made of metallic materials and / or Plastics. The longitudinal side edges of this shaped profile 33 can at least partially frictionally connected to the top of the lower flange 13, as by Adhesive or welding points were indicated schematically and thus a prefabricated core element Represent 26 for a glider 1.

It is essential that the outer longitudinal side surfaces 29, 30 of the inner core member 15 and the inner surfaces of the outer core component 17 assigned to them are not rigidly connected to one another or are not glued to one another, but relative displacements between the core component 15 and the core component 27 against the mechanical Resistance to deformation of the elastic layer 20 remains possible.

For the sake of completeness, it should be mentioned that the extensions 21 or spacer elements 22 also the outer core component 27, in particular the shaped profile 33, with sufficient Completely enforce scope, so that the extensions 21 or spacers 22 directly on the inner core member 15 can be supported. With these breakthroughs for the unhindered Penetration of the extensions 21 and the spacers 22 of the outer core member 27 is also avoided that direct tension between the inner and the outer core member 15 and 27 may occur in the longitudinal direction of the sliding device 1 when the entire core element 26 is bent or bent.

The lower flange 13 and the outer core component 27 with the core component received between them 15 and the elastic layer 20 on its underside 19 can also be a prefabricated, form an independent core element 26, which easily in a manufacturing process can be incorporated for the glider 1. In particular, the multi-part core element 26 under pressure and temperature with the other, load-bearing Layers and layers for a gliding device 1 are pressed in a simple manner.

For the sake of completeness, it should be mentioned that the individual components and layers of the gliding device 1 by means of appropriate adhesive or filler layers 34 to form one piece Composite or sandwich element connected, in particular glued. With these adhesive or filler layers 34 can also individual cavities between the various layers and components are largely filled out.

The core element 26, in particular the core component 15 and / or the core component 27, extends almost over the entire length of the glider 1 and therefore acts as an element to the relative extensive distribution of the more or less selectively acting from the binding Supporting or supporting forces over the length of the gliding device 1. That in the innermost, ie in the center area of the gliding device 1 quasi floating core component 15 with the through the extensions 21 or spacer elements 22 provide mounting options for binding parts favors the driving properties of the glider 1 in a surprisingly high, not predictable extent. In particular, the glider 1 reached by the elastically mounted Core component 15 best, chassis-like driving properties and will also be an optimal Bending stiffness characteristic of the glider 1 reached, which compared to conventional Superstructures also through assembled binding parts and a shoe clamped in between is significantly less impaired. On the one hand, this is caused by the binding no longer with the load bearing or no longer with those for the rigidity of the gliding device 1 responsible, outermost positions of the glider 1 is anchored, but by the core support of these layers and layers in the outer edge zone of the gliding device 1 if possible was decoupled. The core component 15 namely exercises in comparison to the edge layers or to the upper flange 14 the least influence on the bending stiffness of the gliding device 1, the neutral fiber of the gliding device 1 also in the core element 26 or in the core component 27 runs. The inherent dynamic properties of the gliding device 1 are thus quasi core-bearing binding affected as little as possible.

In addition, to achieve an even less influenced by the binding parts bending characteristic the sliding device 1 a support surface 35 for the corresponding binding plate and / or for a corresponding binding part on the respective extensions 21 or spacer elements 22 formed at a distance 36 above the top 5 of the gliding device 1 his. This creates a space between the underside of the corresponding binding part or the corresponding binding plate and the top 5 of the gliding device 1. On the one hand, this free space formed by the distance 36 ensures sufficient Adjustment or damping path in the vertical direction to the sliding surface 3. In addition, the space 36 created by the distance between the binding part and the glider 1 compensation for deformation movements of the gliding device 1 that are as unimpeded as possible The distance 36 can be approximately 0.5 mm to 5 mm.

As can best be seen from FIG. 4, four or five extensions 21 or Spacers 22 for anchoring the fastening screws, not shown in FIG. 4 provided for a binding plate and / or a binding part. It is also clear from this that the extensions 21 or spacers 22 are columnar elements relatively smaller Represent cross-sectional area, which sit directly on the core component 15. In the shown In the exemplary embodiment, the extensions 21 or spacer elements 22 have circular support surfaces 35 for a binding plate or for a corresponding binding part. In the middle area the support surface 35 is at least one receiving bore 37 for anchoring the Fastening screws 25 are provided.

The extensions 21 or spacer elements 22 protrude from the core component 15 assigned openings 38 in the top flange 14, in the cover layer 6 and under certain circumstances also in the second core component 27 at least up to the top 5 of the gliding device 1.

A length 39 measured in the longitudinal direction of the gliding device 1 from that of the edge zone of the Binding assembly area nearest outer openings 38 is larger than an outer width 40 of the respective extension 21 or spacer element measured in the same direction 22. This provides sufficient clearance between the extension 21 or the spacer 22 and the layers penetrated by it.

An outer width 41 of the extensions 21 measured transversely to the longitudinal direction of the gliding device 1 or spacer elements 22 corresponds approximately to the width of the openings 48, so that the extensions 21 or spacer elements 22 fixed immovably in the transverse direction of the sliding device 1 become.

The clearance between in front of and behind the extensions 21 or spacer elements 22 the front and rear boundary surface of the extension 21 or spacer 22 and the wall surfaces of the respective opening 38 which are spaced apart from this are preferably included a relatively soft elastomer 42 at least partially filled.

The closest to the binding assembly center or the inner extensions 21 or spacers 22 can be as close as possible to the outer surfaces of the extensions 21 or Spacer elements 22 adjacent openings 38 emerge from the core zone of the gliding device 1, after hardly in the area of the binding assembly center for ski deflections Compensatory movements are required.

If necessary, it is also possible to use the extensions 21 or the spacer elements 22 to mount corresponding binding plates at the factory. On these binding plates can then the binding parts in a position corresponding to the desired shoe size be held or fastened.

As can be seen in particular from FIG. 2, at least the multi-part core element extends 26 or also the core component 15, which is provided for carrying the binding parts is continuous between a front and a distal rear support area 43, 44 of the unloaded glider 1 on a flat surface 45. In particular extends the core element 26 or the core component 15 for the binding starting from the binding assembly area 46 of the gliding device 1 into the area of contact zones 47, 48 of the sliding surface 3 of the unloaded sliding device 1 with a flat surface 45. The glider 1 is referring to its side view of the largest Longitudinal area arched upwards and has an unloaded state certain preload height 49 between the sliding surface 3 and a flat base 45 on. The core component 15 or core element 26 extends like a bridge between the two contact zones 47, 48 in the two end regions of the gliding device 1 with a base 45th

If two nested core components 15, 27 are formed, it preferably extends the outer core component 27 also runs continuously into the contact zones 47, 48 in the end regions an unloaded glider 1.

5 and 6 is another embodiment of the sliding device 1 for a core bearing illustrated by binding parts. For parts already described above the same reference numerals are used and the previous descriptions are analogous transferable to the same parts with the same reference numerals.

The main difference here is that the core component 15 to at least Extensions 21 projecting flush with the top 5 of the gliding device 1 on the core component 15 are molded. The extensions 21 can by strip or columnar, from the top 23 of the integrated core component 15 projecting elements are formed. The one piece Unit with the core component 15 forming extensions 21 for direct binding support can thereby by milling operations on a workpiece provided for a core component 15 be created. However, it is also possible for the core component 15 to be cast or injection-molded produce and thereby form the extensions 21 in one piece.

As can best be seen from FIG. 5, the core component 15 can in turn consist of several together connected slats 16 are formed from wood. Individual slats 16 point a larger slat width 17 than the other slats of the core component 15 on and thus form the extensions 21 of the core component 15. In particular, this makes it possible at least in the provided binding assembly area 46 strip-shaped extensions 21 on the Form top side 23 of the core component 15. In these strip-like extensions 21 can then schematically indicated fastening screws 25 for a binding plate 50 or for a binding part is screwed in and anchored in the core component 15.

In order to obtain platform-like or column-like extensions 21 that can be seen in particular from FIG. 6, it is possible in a simple manner, the central areas of the strip-like surveys to remove, especially to mill, so that only individual, small-scale surveys in the The area of the intended anchoring points for the fastening screws 25 remain, which lead directly into the core zone of the gliding device 1.

Another difference is that the core element 15 covers almost the entire The peripheral region, in particular on all sides, is delimited by the elastic layer 20. Only the support surfaces 35 for the binding parts on the extensions 21 of the core component 15 are not covered by the elastic layer 20. In particular, the elastic layer is sufficient 20 also delimited by the openings 38 in the upper flange 14 and in the cover layer 6 and the outer or outer surfaces of the columnar extensions 21 over their entire Scope.

In this embodiment, the core component 15 is in the center area of the glider 1 floating in all directions. So here are all the outside surfaces of the core component 15 enclosed or covered by the elastic layer 20. The Transmission of shear, torsion or deformation forces between the inner core part 15 and the outer core component 27 is here exclusively via the elastic Layer 20.

The outer core component 27 in turn delimits the elastic layer 20 like a hood. The Core component 27 also has the openings 38 for the passage of the extensions 21 of the inner core component 15.

The outer core component 27 or shaped profile 33, which is essentially U-shaped in cross section can over the longitudinal side edges of the two legs facing away from the base plate 31, 32 in turn connected to the lower flange 13, in particular welded or glued, his. The middle section of the flat lower flange 13 and that over the legs 31, 32 distanced base plate of the U-shaped profile section 33 form a receiving chamber for the core component 15 with the extensions 21, which is also included in the elastic layer 20 is virtually floating.

In the exemplary embodiment shown, the gliding device 1 has an essentially trapezoidal shape Cross-section and the cross-sectional shape of the upper chord 14 is trapezoidal to this Cross-sectional shape adapted. In addition, the upper chord 14 is supported with its longitudinal side edges in the longitudinal side areas of the lower flange 13 near the steel edges 7, 8.

As best seen in FIG. 6, the elastomeric layer 20 emerges from the core area of the gliding device 1 and closes at least flush with the top 5 of the gliding device 1 from.

6 clearly shows that the elastic layer 20 all the extensions 21, namely also the inner extensions 21 in the binding assembly area 46, protruding bounded from the inside of the glider 1 outside. This is achieved by the opening widths the openings 38 are dimensioned larger than the respective width and length dimensions of the projections 21 passing through.

7 and 8 is a further advantageous embodiment for storage or mounting a binding part, for example a ski binding or possibly a snowboard binding, illustrated on a corresponding glider 1. Thereby were for previous Parts already described used the same reference numerals and are above Descriptions can be transferred analogously to the same parts with the same reference symbols.

In this case, the board-like gliding device 1, in contrast to the aforementioned designs whose top 5 has a profile 51 or shape. In particular, at the Top side 5 of the gliding device 1 at least two running in the longitudinal direction of the gliding device 1, bead-like elevations 52, 53 formed with an intermediate recess 54. In the longitudinal direction of the gliding device 1 there are at least two bead-like strands, which referring to its cross-section or referring to the cross-section of the gliding device 1 result in a wavy upper edge or upper side 5 of the gliding device 1.

This profiling 51 of the top of the glider is at least in the middle region of the glider 1 provided. The elevations 52, 53 can close to the end regions or to close to the bearing areas 43, 44 of the unloaded glider apparent from FIGS. 1 and 2 1 on a level surface 45 is sufficient. Starting from the central area of the glider 1 in the direction of its end regions, the elevations 52, 53 flatten continuously and gradually go into a flat top 5 in the blade and end area of the glider 1 over.

In the exemplary embodiment shown, the profile 51 of the sliding device 1 also extends within the binding assembly area 46. Of course, it is also possible to Binding mounting area 46 as a largely flat receiving zone for a mounting rail 55 or to form for a binding part 56. The profiling 51 of the gliding device 1 then runs from both ends of a flat binding assembly area 46 to the respective end areas of the gliding device 1. The binding assembly area 46 in this case represents a plateau-like, flat receiving zone for a binding plate 50 and / or for mounting rails for holding binding parts 56.

Instead of the elevations 52, 53 constructed in the shape of an arc in cross section, it goes without saying also possible any other profiles for the top 5 of the gliding device 1 to provide and the advantageous, objective binding holder or binding use.

As can be seen above all from FIG. 7, the gliding device 1 can also do significantly more than two Have layers or layers above the at least one core element 26. In which illustrated embodiment are below the cover layer 6 at least two separate, arranged relatively hard layers of the upper chord 14. Between these two relatively hard to The top chord of 14 layers is then a comparatively soft, elastomeric intermediate layer 57 arranged. The top or bottom of this elastic intermediate layer 57 is thereby, for example by an adhesive or vulcanization process, with one of the two comparatively hard and high-strength layers of the multilayer upper flange 14 non-positively connected. As a result, all are over this elastic intermediate layer 57 Shear, pressure, tensile and torsional forces from the upper position of the upper chord 14 to the lower one Position of the top chord 14 and vice versa. The hard layers of the top chord 14 can also consist of different materials. In particular, the top Position of the upper chord 14 may be formed from a metallic material, whereas the lower layer of the upper belt 14 predominantly made of plastic, for example resin-impregnated Tissues that can exist.

In this embodiment of the gliding device 1, there is also a significant difference in that inside the gliding device 1 two separate ones, running in the longitudinal direction of the gliding device 1 Core elements 26 are integrated.

These two core elements 26 run essentially parallel or congruent the respective bead-like elevations 52, 53 of the upper side of the glider. Those are preferred Integrated core elements 26 largely in the center of an imaginary, in the longitudinal direction of the Gliding device 1 extending apex line 58 of the respective elevation 52, 53 is arranged. In particular can a longitudinal central axis 59 of a core member 26 when looking at the Gliding device 1 is essentially congruent with the respective apex line 58 of the corresponding one Elevation 52, 53 can be aligned, as can be seen above all from FIG. 8. After this through the elevations 52, 53 of the gliding device 1 relatively generous space are created, the respective core elements 26 can have relatively large cross-sectional dimensions or have cross-sectional heights and still be effortlessly integrated into the glider structure become.

The apex line 58 connects the apexes of the respective arcuate elevations 52, 53 in individual cross-sectional areas spaced apart from one another in the longitudinal direction of the sliding device 1 of the glider 1 and can therefore also as a ridge line or as the top Boundary line between the falling surface areas of a survey 52 or 53 defined become.

Each multi-part core element 26 in turn comprises an outer shaped profile 33, which at least partially surrounds or encloses the inner core component 15. In this embodiment the inner core component 15 is also formed by a shaped profile 60. The inner Shape profile 60 and the outer shape profile 33 have the same or at least similar Cross-sectional shapes, the cross-sectional dimensions of the internal shape profile 60 naturally have to be made smaller.

In a preferred embodiment, the nested shape profiles 33 and 60 largely circular cross-sectional shapes. In particular, these can be divided into several parts Core element 26 composite molded profiles 33 and 60 formed by tubes his. To better adapt these shaped profiles 33, 60 to the usual profile of the cross-sectional height of the sliding device 1, the shaped profiles 33, 60, starting from the central area towards its end regions or towards the end regions of the Sliding device 1 are increasingly flattened. The shaped profiles 33, 60 can in this End areas or in the end areas of the gliding device 1 may also be flattened to the extent that the ends of which are flattened and thus a core element closed in its end regions 26 is created. Of course, it is also possible in the end areas of the Form profiles 33, 60 or in the end regions of the multi-part core element 26 separate To provide caps or plugs in order to seal a to create hollow core member 26.

Instead of hollow, tubular core components 15 and 27 for a multi-part core element 26 use, it is of course also possible to use shaped profiles 33 and 60 of different cross-section use. For example, the shaped profiles 33, 60 can also be square, have a rectangular, triangular, trapezoidal or elliptical cross section or others Assume cross-sectional shapes composed of it. The upper one is preferred Jacket area of the composite core element 26 at least approximately to the Surface contour or adapted to the profile 51 of the final gliding device 1 his. Through the at least partial alignment of the upper lateral surface of the outer shaped profile 33 or the core element 26 to the profile 51 of the top 5 of the gliding device 1 can be determined by the usual glider dimensions, relatively cramped Space can be used optimally. In addition, cheap static or mechanical Properties of the glider 1 achieved.

Instead of a hollow, inner shaped profile 60, it is of course also possible to use the inner one Shape profile 60 by a solid body, in particular by a bending rod or by to form a corresponding rod, such a part being inserted into the outer shaped profile 33 and is largely enclosed by the outer molded profile 60. The outside dimensions, in particular the cross-sectional width and the cross-sectional height of the interior Shape profile 60 are dimensioned such that there is scope in the outer shape profile 33rd can be used or that the shaped profile 60 nested with the shaped profile 33 can be.

This clearance between an outer shell 61 of the inner profile 60 and an inner surface 62 of the outer shaped profile 33 is in turn at least partially from the elastic layer 20 filled. The elastic layer 20 is therefore between the outer jacket 61 of the inner core component 15 and the inner surface 62 of the outer, a receptacle or boundary for the inner core component 15 constituting core component 27. This elastic layer 20 holds the inner core component 15 or the inner shaped profile 60 in Distance to the inner surface 62 of the outer core member 27 or at a distance to the corresponding Form profile 33 and this unit results from the first core component 15, second core component 27 and interposed elastic layer 20 a multi-part, one-piece core element 26. This multi-part core element 26 provides an ideal static characteristic value and dynamic bending properties having a bending rod, which simply in a Integrate glider 1.

The shaped profile 33 or 60 is preferably formed from a metallic material. In particular are suitable profiles 33, 60 made of aluminum or a high-strength and lightweight Aluminum or titanium alloy. Of course, it is also possible to use plastic existing shape profiles 33 and 60 and / or woven from individual fibers or threads and if necessary, integrate elements reinforced with binder into the gliding device 1.

In the embodiment shown, the extensions 21 are for receiving fastening screws 25 for a binding plate 50 and / or for a mounting rail 55 and / or for a corresponding binding part 56 directly on the inner core component 50 or directly on the corresponding one molded profile 60 on the inside. These extensions 21 on the inside, about the elastic layer 20 vibration-damping molded profiles 60 enforce this outer shape profile 33 and the layers of the upper chord 14 via openings 38 in these Elements. It can thus be stated that the inner core component 15 or the inner one Form profile 60 in a designated receiving area for fastening screws 25 for Binding parts 56 penetrates the outer shaped profile 33 and the supporting upper chord 14.

Instead of the illustrated extensions 21 which are integrally formed on the inner shaped profile 60 it is of course also possible to have a separate, to provide sleeve-like spacer 22, which is provided by a corresponding fastening screw 25 is interspersed loosely. In this case, the tip of the fastening screw is then found 25 exclusively in the inner core component 15 its anchoring and presses the built-up bias between the binding part and core element 15, the spacer sleeve against the top of the elastically mounted core component 15. In such an embodiment the shaped profile 60 is to be made relatively thick-walled or as a rolling body in order to to achieve a secure anchoring of the fastening screws 25 in the core element 15. A comparatively high pull-out strength for the fastening screws 25 is, however reached when the extensions 21 are integrally formed on the inner shape profile 60 and fastening screws 25 are already anchored in the material of the extensions. In this case, the location holes are 37 formed for the fastening screws 25 through blind holes. In deviation from the embodiment shown, it is of course also possible to form the receiving holes 37 through holes which are directly in the Guide cavity of the inner mold profile 60.

In the exemplary embodiment shown, the two elongate core elements 26 distance Layers of the lower flange 13 from the layers of the upper flange 14. In particular, the lower flange lies 13 directly on the underside of the outer shaped profile 33 and is also a bottom of the Upper chord 14 directly on the facing top of the outer molded profile 33. The remaining one There is free space between the core elements 26 and the lower or upper flange 13 filled with an adhesive or filler layer 34. This adhesive or filling layer 34 can also be formed by a foam plastic, which then also as a foam core can be designated. The core element 26 can at least within partial areas the contact points with the lower or upper flange 13, 14 non-positively connected, in particular glued or welded.

The adhesive or filler layer 34 in the core area of the gliding device is preferably by a relatively light foam plastic formed, which also have permanently elastic properties can.

As can be seen in particular from FIG. 7, the longitudinal side walls 9, 10 of the gliding device 1 u.a. due to independent side cheek elements 63, 64 which vary in thickness or height formed, which is the transition between the lower layers and the upper layers of the Represent glider 1 or form the side cheeks 11, 12 of the glider 1.

9 shows a further embodiment relating to the mounting or mounting of a binding part illustrated on a glider 1. For previously described Parts have been given the same reference numerals and are previous descriptions analogously applicable to the same parts with the same reference numerals.

In this case, the core component 15 extends only within the usual binding assembly area 46 and end faces 65, 66 of this core component 15th largely free of play and assigned, spaced apart in the longitudinal direction of the sliding device 1 Boundary surfaces 67, 68 of a recess 69 in the core component 27.

This recess 69 in the top 23 of the core component 27 is dimensioned such that therein the core component 15 for the binding holder is at least partially accommodated can. In the embodiment shown, the depth of the recess 69 is approximately that Half of the core component 27. Between the bottom 19 of the core component 15 and the bottom surface the recess 69, in turn, the elastic layer 20 is formed. This will achieved that the core member 15 for the binding in the vertical direction to the top 5 of the gliding device 1 and the deformation of the elastic layer 20 is adjustably mounted.

Due to the largely play-free end faces 65, 66 and boundary surfaces 67, 68 is achieved that the core member 15 in the longitudinal direction of the glider or in Longitudinal direction, the core member 27 is fixed immovably.

The core component 15 in turn carries extensions 21 and / or, if appropriate, accordingly Spacers 22, which protrude from the top 23 of the core component and at least reach to the top 5 of the glider 1. Appropriate breakthroughs are in turn for this 38 or elongated holes in the layers of the glider arranged above the core component 1 trained.

In the embodiment shown, only those in the binding assembly area 46 are complete outer extensions 21 is shown and was based on a representation of the middle extensions dispensed with for anchoring medium fastening screws 25. From Fig. 9 is also clearly visible that the lying in the edge zones of the binding assembly area 46 Openings 38 are formed by elongated holes pointing in the longitudinal direction of the gliding device 1 are.

9 that the multi-part core element 26 is of an elastic type Envelope 70 is surrounded, which is an elastically resilient embedding of the multi-part Allows core element 26 in the glider construction. This elastic wrap can be made of a covering 70 made of an elastomeric rubber compound or Foam plastic can be formed.

This envelope 70 also enables damping of movements which cause lifting cause the core member 15 from the core member 17.

The illustrated, one-piece design of the extensions 21 on the integrated in the glider body Core component 15 enables highly secure anchoring of fastening screws 25 for binding parts 56 after the fastening screws over a wide range the height of the extensions 21 and the height of the core component 15 can be anchored. In particular can be avoided by this configuration that the mounting screws also penetrate into the outer core component 27 and thereby the intended damping function or the intended longitudinal compensation between the core components 15 and 27 is lost.

For the sake of order, it should finally be pointed out that for a better understanding of the Construction of the gliding device 1 of this or its components partly to scale and / or were shown enlarged and / or reduced.

Above all, the individual in FIGS. 1, 2, 3, 4; 5, 6; 7, 8; 9 versions shown form the subject of independent solutions according to the invention. The related, Tasks and solutions according to the invention are the detailed descriptions of these figures refer to.
