The elastic connecting unit comprises an elastomeric damping element arranged in a passage of the power transfer element.

Description

The invention relates to a ski or a snowboard in the form of a board-like sliding device, as specified in claim 1.

The DE 2417156 A1 describes a ski, which consists of at least two juxtaposed sliding strips. These sliding strips are connected to one another via fastening means such that relative movement of the two sliding strips in the vertical direction to their sliding surface is made possible, at least in their middle section. As a result, a multiple, in particular a double edge support is achieved, which should allow an improved grip against lateral slipping. The mechanical coupling between the two Gleitleisten requires complex devices, whereby such a structure has little practicality.

The DE 4130 110 A1 describes a ski with a spatially profiled top. The ski is formed by a one-piece composite body, which consists of a plurality of adhesively interconnected layers or layers. In particular, this one-piece ski comprises a top flange, a bottom flange, side cheeks and a core enclosed by these elements. The upper belt is formed from several layers. Between a layer of the upper belt and a surface layer or the core, an intermediate layer is arranged, which has a different thickness and / or width in the longitudinal direction. This intermediate layer may have a support and / or damping element or be formed by this. The ski binding is fastened by fastening means, such as screws, on the one-piece ski, for example via the intermediate layer and / or the core. In particular, the binding fastening screws extend into the core element of the ski and terminate just before the underside of the ski. The glued on top of the ski body or integrally molded upper chord construction with abruptly varying width and / or thickness dimensions in this case has sudden effects on the stiffness of the integral, multi-layer ski. In addition, such a ski in the region of the binding mounting zone, in particular in a shoe used in the ski binding, made relatively stiff.

The WO 00/62877 A1 describes an alpine ski with a composite of several elements body, on its underside a tread and on its top one Has area for fixing a bond. Its structure furthermore has at least one upper belt element subjected primarily to pressure and at least one lower belt element subjected to tension. The upper belt element has in the middle region of the ski in the form of a flat, upwardly curved arc which extends in the longitudinal direction of the ski and spans the lower belt element. In this case, the arc of the upper belt element can be deflected in the direction of the lower belt element as a function of the load originating from the binding. The upper chord member is supported at the end portions of the ski such that displacement of the ends of the upper chord member resulting from deflection of the arch increases the bearing portion of the end portions of the ski. With this embodiment, a more uniform surface pressure distribution over the running surface of the ski can be achieved. Furthermore, the greatest possible contact length of the Schikanten can be achieved and the straight-line stability and the reaction of the alpine ski to control impulses of the skier can be improved somewhat. However, the achievable driving dynamics or the achievable with this training driving pleasure is still not satisfactory satisfactory for many skiers.

The WO 2004/045727 A1 describes an alpine ski with a ski body, which has a running surface on its underside and on its upper surface facing away from the running surface has at least one, in the longitudinal direction of the ski body extending, tensile and compressive forces receiving Obergurtelement. This Obergurtelement is supported with its ends on the ski body, wherein on the upper side of the ski body a wave-shaped support structure is arranged, on which the Obergurtelement is mounted. The wave-shaped support structure is formed from an elongate, flat component, which is bent at intervals about substantially parallel, transverse to the longitudinal direction of the ski extending axes in alternating directions in each case at an angle to the tread. This should give good running characteristics and a good controllability of the alpine ski. In particular, a favorable compromise between the bending elasticity on the one hand and the torsional stiffness of the ski on the other hand is made possible. In addition, an advantageous, uniform surface pressure distribution is achieved. Also, this structure is satisfactory in terms of achievable driving dynamics only for a limited circle of skiers.

In the DE 198 36 515 A1 The applicant is a distribution device for on a sports equipment to be transmitted loads and / or forces, and a correspondingly equipped sports equipment specified. The distribution device comprises a support element for a Coupling device for holding the sports shoe of a user. This plate-like support member for the coupling device is in its end via joint arrangements with a board-like sports equipment, in particular a ski, connectable. At least one end region of the plate-like support element is pivotally connected via one of the joint arrangements with an intermediate carrier, which in turn is supported by two spaced apart in the longitudinal direction of the support member joint arrangements on the board-like sports equipment and / or on a further support bracket. By means of this support structure consisting of a plate-like support element for the coupling device and a plurality of intermediate supports and joint arrangements arranged between the upper side of the sports equipment and the support element, the forces to be transmitted from the support element to the sports equipment, in particular starting from the central area, should be distributed as evenly as possible. The disadvantage here is that the arcuate intermediate carrier and the respective connecting joint arrangements increase the complexity of the structure, whereby the total weight of such a sports equipment is relatively high. In addition, the riot height for the user's foot relative to the running or sliding surface of the sports equipment is relatively high and the various joint assemblies and longitudinal guides difficult to ensure the desired rotational mobility and longitudinal displacement between the respective components under adverse conditions.

The US 3,260,531 A and the US 3,260,532 A describe similar force distribution and support structures as in the previously cited document. This Konshruktionen should give a ski, which is as adaptable to various terrain forms as possible, by having a high degree of flexibility and the lowest possible torsional stiffness. For this purpose, elastic and / or articulated or length-compensating coupling devices between a support plate for a user's shoe and the actual sliding board body are proposed. These constructions, which are intended to allow the most flexible adaptation of the gliding board body to the respective terrain, offer a user no satisfactory sliding or guiding properties. In particular, the controllability of such Schiconstruktionen is unsatisfactory for the user.

The EP 0 490 044 A1 describes a ski, which has a lower sliding board body and an attached at its top, elongated stiffening element, which with the top of the sliding board body is coupled by a flexible or partially rigid connection. The lower gliding board body is defined by a standard ski construction by adhesively bonding several strength-relevant layers and a core member. The stiffening element, which extends over more than 50% of the length of the sliding board body, is designed as a multilayer sandwich construction according to a first embodiment ( Fig. 3 ) connected to the top of the glide board body via an elastically compliant adhesive layer. This multilayer, sandwich-type reinforcing element has on its upper side and on its side walls on a decorative cover layer, which determines the appearance of the stiffening element. According to a second embodiment ( Fig. 4 ) has been proposed to form the stiffening element of a composite material and to form the cross-section hat-shaped or in the manner of an omega, wherein the two aligned substantially parallel to the top of the sliding board body flanges of the substantially hat-shaped stiffening element via an elastically resilient layer with the top the gliding board body are glued surface. According to a first embodiment, the jaw bodies of a binding device are supported on the upper side of the stiffening element (FIGS. 18-21). Alternatively, it has been proposed to provide bridge-like support elements for the jaw body of a ski binding. These bridge elements extend transversely across the stiffening element and are each supported on the longitudinal side edges of the sliding board body. The stiffening element is thereby decoupled from the forces acting on the ski binding forces and the forces exerted by the ski binding forces are transmitted directly to the longitudinal side edges of the sliding board body. These bridge elements cause increased production costs and the connection of the bridge elements with the sliding board body is difficult in terms of production technology. In addition, the sliding board body is considerably stiffened in the connecting portion with the bridge elements, whereby the use performance of the overall construction is impaired. How to carry out the connection of the jaw body of the ski binding against the stiffening element or against the at least one bridge element remains unclear.

The EP 0 490 043 A1 discloses very similar structures of a ski compared to the previously described embodiments. This ski comprises a sliding board body, on the upper side of which a cross-sectionally plate-shaped or hat-shaped stiffening profile is mounted. The ski binding is supported on at least one bridge element, which is the stiffening element bridged across the direction of the ski. The at least one bridge element can be fastened to the top side of the gliding board body via an elastically yielding or flexible connection (FIGS. 13, 14, 17, 18) or via a rigid connection (FIG. 16). The at least one bridge element for holding and supporting the ski binding may further be adjustably held in the ski longitudinal direction via a guide rail (FIG. 15) in order to allow adaptation to individual shoe sizes or to allow a start-up suspension known per se between the front and heel shoes of a ski binding , These previously known embodiments have, inter alia, the disadvantages described above. In addition, the bridge elements increase the footprint of a user's foot relative to the sliding surface of the sliding board body to a considerable extent. Due to the changed, relatively extreme leverage increases the risk of injury to the user. Measures for fastening the jaw body of the ski binding on the stiffening element or on the bridge elements are not to be found in this document.

The AT 007 540 U1 describes a gliding board, in particular a ski, with an anchored to the top interface element, which is provided for the arrangement of at least one binding element of a ski binding. This interface element, which is designed in the manner of a guide rail arrangement, is connected by means of at least one anchoring element with the sliding board, wherein the anchoring element during manufacture of the sliding board with the core of the sliding board is positively or frictionally engaged or otherwise mechanically connected. Accordingly, these assembly measures are to be taken immediately during the manufacture of the gliding board body, whereby a compelling restriction to a specific type or a specific type of ring of seals already exists in the production of the gliding board body. In addition, this makes the manufacturing process for the ski much more expensive.

The US 5,820,154 A describes a generic, board-like gliding device in which the upper power transmission element, on which the ski binding is supported, is supported by a plurality of elastically yielding layers and by at least one relatively pressure-resistant layer on the upper side of a gliding board body. The upper part for mounting the ski binding is made comparatively thick-walled within the binding mounting area in comparison to the sliding board body. Measures for fixing the ski binding can not be found in this document.

The DE 38 03 483 A1 describes a method of making a ski composed of multiple layers and having an intermediate core. The upper cover layer of this ski covers the upper side and the longitudinal side walls of the ski body. Such Schikörper can easily be made relatively thick-walled or stable in the binding mounting area, whereby the fastening screws for binding body easily find sufficient support.

The WO 95/33536 A1 describes a snowboard on the top of a support plate is supported for the assembly of snowboard bindings. This support plate is stationary or immovably connected to the snowboard at one end portion, whereas the opposite end portion of the support plate is connected to the snowboard such that a bending-related longitudinal compensation between the snowboard and the support plate is made possible. In what way the snowboard bindings to be mounted on the support plate, this document is not apparent.

The AT 376 373 B describes a ski with device parts to increase its flexural rigidity. Here, an elastically deformable band is formed on the Schioberseite, which is biased individually adjustable by means of at least one height-adjustable, the Schiober side unyielding support. How a ski binding is to be attached remains completely open.

The DE 4130110 A1 describes a ski with spatially profiled top. This ski has a top flange, a bottom flange, as well as side cheeks and a core enclosed by these elements. The upper belt is formed from several layers and has an intermediate layer between a layer of the upper flange and a surface layer. This intermediate layer has different thickness dimensions and / or width dimensions in relation to the longitudinal direction and is designed as a support and / or damping element or provided as such. The upper, profiled section and the lower, board-like section of this ski are adhesively connected and form a one-piece ski body. The attachment of the jaw body of the ski binding via screw-like fasteners, which extend into the core of the ski basic body.

The WO 2004/045727 A1 describes an alpine ski with a lower ski body, which has on its upper side a support structure on which a compression element receiving upper belt element is mounted. This support structure is formed from an elongate, flat component, which at intervals about substantially parallel, transversely to the longitudinal direction of the ski extending axes in alternating directions each bent at an angle to the tread, in particular wave-shaped. The support structure is at least partially covered on its upper side by a thin-walled, plate-shaped element. This plate-shaped element serves to support a ski binding. How this support and the connection is to take place is not removable.

The present invention has for its object to provide a ski or a snowboard, which or which has improved handling characteristics, the achievable with such Gleitbrettkörper use performance should be as high as possible. In particular, an improved cornering behavior should be achieved.

This object of the invention is achieved by a board-like sliding device according to the features in claim 1. It is essential that the ski according to the invention or the snowboard according to the invention offers significant advantages in terms of its driving characteristics in comparison to the known from the prior art board-like sliding devices. In particular, a ski or snowboard is created whose vibration behavior and thus its driving behavior is significantly influenced by the plate-like power transmission element, the winter sports equipment according to claim achieve especially excellent edge grip or steering stability, which in particular when driving through curves or for an accurate swing release of is of increased importance. In particular, the specified, plate-like power transmission element gives the gliding board body precisely that stability or strength which is desirable in order to be able to set cut or so-called "carved" turns as safely as possible into the snow. The claimed board-type gliding device gives the user the required, sufficiently high stability and ensures the claimed gliding device as a whole a high controllability and leadership stability. Above all, it is avoided that with increasing load of the gliding device during a swing phase, the sliding board body in contact with the ground unexpectedly yields or virtually collapses and suddenly a difficult to control behavior the board-like sliding device occurs. In particular, within a relatively high load range of the sliding board body, a harmonious or uniform swing guide can be achieved, which also increases the personal safety when using the sliding board body according to the invention. The specified, plate-like force transmission element thus stabilizes the claimed changed sliding board so that a good controllability and a favorable leadership behavior can be achieved. In particular, suppresses or reduces the plate-like power transmission element in at least one end portion of the gliding board body high-frequency vibrations in the vertical direction to the tread surface, as especially when driving fast on relatively rough slopes, especially during cornering, is beneficial. It is also advantageous that the forces applied by the user or the user-initiated control movements can be initiated with the interposition of the force transmission element in those sections of the sliding board body in which the plate-like power transmission element can develop the most or best effect against the sliding board body.

In addition, it is achieved by the construction according to the invention that an enlarged engagement depth or a higher, effective thread length is available for the screw-like fastening means of the binding device, whereby a high pull-out strength for the screw-like fastening means is achieved. Nevertheless, the thickness or the vertical height of the plate-like power transmission element can be chosen relatively small, so that the overall height of the sliding device, in particular the contact height of the user of Gleitgerätes against the ground, can be kept low, although the sliding board body is a plate-like power transmission element structurally superimposed. In particular, a relatively high overall or thread length can be selected for the screw-like fastening means of the binding device, wherein these screw-like fastening means are anchored with sufficient Ausreißsicherheit exclusively in the plate-like power transmission element. In particular, the helical fastening means do not penetrate into the upper side of the gliding board body underneath or the helical fastening means are not anchored in the gliding board body and nevertheless the required tear-out strength can be achieved without difficulty. Along with this, a favorable bending behavior, in particular an improved bending characteristic for the gliding board body, is achieved after the gliding board body remains elastically deformable in relatively large sections relative to the plate-like force transmission element in a relatively homogeneous shape.

The measures according to claim 2 offer the advantage that, despite relatively thin executable plate height of the plate-like power transmission element, a high tear resistance of the screw means for mounting a binding device is achieved. Nevertheless, it is ensured that the plate-like force transmission element with the binding device fixed thereon remains slidable in the longitudinal direction as freely as possible relative to the sliding board body arranged underneath, so that tension between the said components is minimally avoided during deflection thereof.

In the embodiment according to claim 3, it is advantageous that a guide device extending in the longitudinal direction of the sliding device is provided which increases the transverse stability between the plate-like force transmission element and the gliding board body. In particular, this high forces between the sliding board body and the plate-like power transmission element can be transmitted without deviating movements occur or without increased risk of damage to said components is given. Furthermore, due to the partially positive coupling between the plate-like force transmission element and the gliding board body, the additionally required connecting elements between said components, in particular fastening screws, are dimensioned smaller and / or reduced in number and / or optimized in their positioning.

Also advantageous are the measures according to claim 4, characterized in that in those sections in which the sliding board body and / or the plate-like power transmission element has its greatest thickness or strength, a pronounced positive connection is constructed, which increases the quality of the connection between said components. On the other hand, reduces the formation of the positive connection in those sections of the sliding device in which the sliding board body and / or the power transmission element has a comparatively lower strength or height. In particular, this avoids that the gliding board body is additionally weakened in those sections in which it has a comparatively low profile. An advantage of this embodiment is also that the high elongation, positive coupling a high torsional stability between the plate-like Kraflübertragungselement and the sliding board body, with reference to an axis extending vertically to the tread surface, is achieved.

In the measures according to claim 5 or 6 is advantageous that can occur within the at least one connection zone plane relative displacements between the plate-like power transmission element and the sliding board body, said relative displacements elastically yielding resistance is set against. In particular, these relative displacements are quasi cushioned and gradually limited after covering a defined Relativverschiebungsweges. This path limitation is dependent on load or force. In particular, when the occurring deformation force is no longer sufficient to overcome the elastic deformation resistance, a bending-dependent relative movement between the plate-like force transmission member and the sliding board body is gradually stopped.

Another advantage is an embodiment according to claim 7, characterized in that a particularly robust, elastically flexible connection means between the plate-like power transmission element and the sliding board body is created. In particular, the elastomeric damping element is thereby reliably supported or supported and can withstand relatively high loads without the risk of tearing or shearing of the damping element. Of particular advantage is further that the damping element is designed in the plate-like power transmission element and is not associated with the sliding board body. Characterized different characteristics can be achieved in a relatively simple manner by attaching different power transmission elements or damping elements on a standard sliding board body. In particular, a particular type of gliding board body can be optionally equipped with or without the plate-like power transmission element, which can bring economic benefits to the producer and / or relatively low cost to the users of Gleitbrettkörper.

In the embodiment according to claim 8 is advantageous that a particularly break or tear-resistant connection between the plate-like power transmission element and the sliding board body can be created. In addition, the production cost for the production of the board-like sliding device can be kept low, since a relatively short assembly time for the connection between the plate-like power transmission element and the sliding board body can be achieved. In addition, long-term reliable, board-like gliding devices can be created, their properties even after long-term or intensive Use remains largely constant. In particular, gradual loosening of fastening screws due to widening of the material for a tight fit of the fastening screws are better prevented or avoided. Furthermore, it can be created Gleitbrettkörper or two- or multi-part composite, board-like gliding devices that are relatively low in terms of their overall height, since with comparatively small screw-in depths for the mounting screws of the plate-like power transmission element Auslangen can be found. In particular, despite relatively small thickness of the sliding board body or despite relatively low screwing the correspondingly required tear-out or connection quality between the plate-like power transmission element and the sliding board body can be ensured.

By means of the measures according to claim 9, referring to the plan view of the plate-type force transmission element, relatively large-area damping elements can be used which have an optimized damping characteristic or elasticity. In addition, the mechanical stress of such damping elements can be kept as low as possible due to their relatively far-reaching extent. Further, while the damping element is secured in a simple and reliable manner from falling out or tearing out of the plate-like power transmission element. Optionally, it can also be used by default fixing screws for mechanical coupling between the plate-like power transmission element and the sliding board body, whereby the total cost of producing the board-like sliding device can be kept as low as possible.

By the measures according to claim 10, the stabilization and at the same time damping function of the plate-like power transmission element is transmitted to correspondingly far-reaching longitudinal sections of the sliding board body. In particular, the multi-functional effect, i. provided the damping and stabilizing effect of the plate-like force transmission element with respect to the sliding board body to a high degree, without structurally complex measures would be required.

The embodiment according to claim 11 provides the advantage that the force transmission element can act with high efficiency on the sliding board body after the Kraflübertragungselement extends over extensive sections of the sliding board body. Especially acts such a force transmission element near the end portions of the sliding board body on the sliding board body, whereby on the one hand a good stabilizing function and on the other hand sufficiently striking damping or cushioning of the sliding board body is accomplished in at least one of its end sections.

Another advantage is an embodiment according to claim 12, as a highly stable coupling and a possible delay-free or direct power transmission between the power transmission element and the sliding board body can be created. In addition, the requirements for the screw connection, in particular with respect to anchoring strength or tear resistance, can thereby be reduced, and yet a highly stable coupling between the force transmission element and the gliding board body can be achieved.

In the measures according to claim 13 it is advantageous that a pronounced, positive coupling between the power transmission element and the sliding board body can be made without the standard structure of a sliding board body, especially an alpine ski, would have to be drastically changed to the required capacity and an advantageous To be able to achieve ease of the distal end portions of the sliding board body. In particular, almost standard construction methods, which have proven themselves many times in practice, can be maintained in order to be able to create the sliding device according to the invention comprising the sliding board body and the power transmission element mounted thereon in the most cost-effective and proven manner.

Of particular advantage is also the embodiment according to claim 14, as this tension between the plate-like power transmission element and the sliding board body are prevented as possible. In particular, this ensures that the end portions of the plate-like force transmission element relative to the sliding board body can cover a correspondingly wide Relativverschiebungsweg when the sliding board body and the plate-like power transmission element is subjected to elastic deflection, as occurs for example when driving on troughs and especially when driving through a curve. This promotes a sufficiently pronounced influence on the cross-sectional or side edge geometry of the sliding device. Furthermore, this ensures that the gliding board body has an ideal bending characteristic curve, especially after being in the region of the assembly zone for a binding device in its bending behavior of the plate-like Power transmission element is influenced as little as possible, so that a harmonic as possible, uniform bending characteristic can be achieved. By means of the measures according to claim 15, a package of board-type or plate-like elements is virtually created, which permits longitudinal relative movements between the underside of the plate-like force transmission element and the top of the sliding board body, if the overall construction is subjected to an arcuate, elastic deflection. At the same time deviation or detachment movements in the transverse direction to the longitudinal axis of the sliding device increased resistance is given or such transverse displacements are as completely as possible prevented. This also favors the driving or sliding behavior of the ski or snowboard according to the invention.

Due to the configuration according to claim 15, the plate-like power transmission element despite relatively low height achieve a relatively high stability or torsional rigidity. In particular, when the width of the plate-like force transmission element approximately follows the width of the Gleitbrettkörpers and the width dimensions of the plate-like force transmission element substantially correspond to the width dimensions of the Gleitbrettkörpers or are only slightly smaller, a relatively lightweight and at the same time relatively stable, plate-like force transmission element can be created.

Advantageous embodiments of the invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

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 or 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 these are mutatis mutandis to transfer to a new position on a change in position.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

In the Fig. 1 to 5 is a preferred embodiment of a board-like sliding device 1 with improved handling characteristics, in particular striking damping or cushioning properties shown. In particular, a ski 2 is shown schematically, whose sliding or cornering behavior and its inherent dynamics are advantageous for a plurality of users, wherein in these figures, only the most essential components are shown by way of example. In addition, only the most essential sub-components, in particular the sliding board base body and the plate-like force transmission element are illustrated in individual figures.

Preferably, the board-like sliding device 1 is formed by a ski 2 or by a snowboard. In a known manner, such a ski 2 is to be used in pairs, whereas the user of a snowboard is supported with both feet on a single sliding board body. To connect the feet of the user with the gliding device 1, this comprises at least one binding device 3, which can be designed as a safety trigger binding or as a relentless coupling coupling.

The board-like sliding device 1 is designed in sandwich or monocoque construction. That is, a plurality of layers are adhesively bonded to each other and together form the one-piece main body of the sliding device 1. In a manner known per se, these layers form at least one strength-relevant upper flange 4, at least one strength-relevant lower flange 5 and at least one core 6 arranged therebetween. The upper belt 4 and / or the lower belt 5 can be formed from at least one plastic layer and / or metallic layer and / or fiber layer and / or epoxy resin layer or the like. The core 6 can - as known per se - made of wood and / or foam plastics. The core 6 essentially distances the strength-relevant upper belt 4 from the strength-relevant lower belt 5 of the sliding device 1.

The upper side 7, ie the upper outer surface of the sliding device 1, is formed by a covering layer 8, which predominantly fulfills a protective and decorative function. The underside 9, ie the lower surface of the sliding device 1, is formed by a tread covering 10, which has the best possible sliding properties against the corresponding substrate, in particular with respect to snow or ice. The cover layer 8 may extend at least partially over the side cheeks of the board-like sliding device 1 and together with the tread surface 10 form a box-like structure, as in particular the cross-sectional view according to Fig. 4 can be seen. The lateral edges of the tread 10 are preferably limited by control edges 11, 12, preferably made of steel, to allow as exact as possible or largely non-slip guidance of the sliding device 1, even on relatively hard ground. The essential for the control and management of the sliding device 1 control edges 11, 12 are rigidly connected to the structure, in particular with the outsole or the lower flange 5 of the sliding device 1. Preferably, the control edges 11, 12 - as known per se - positively and non-positively defined in Gleitgeräteaufbau. Similarly, the tread surface 10 over its entire, the core 6 facing Flat side with the Gleitgeräteaufbau, especially firmly connected to the lower flange 5. Preferably, the tread surface 10 is glued over its entire surface with the surrounding components of the sliding device 1. The running surface covering 10 or the underside 9 of the sliding device 1 is in the original, unloaded state of the sliding device 1 in cross section through the binding mounting portion according to Fig. 4 made straight or flat, so that the slider 1 in the unloaded initial state, a substantially flat bottom 9 or outsole is present.

The above-described construction significantly determines the strength, in particular the bending behavior and the torsional rigidity of the board-like sliding device 1. These strength values are predetermined or predetermined by the materials and layer thicknesses used and by the connection methods used. It is essential that on the upper side 7 of the actual sliding board body, a plate-like force transmission element 13 is at least in force supported or load-transmitting at least within sections. A structurally predefined sidecut or lateral shape of the sliding device 1 results in a varying width of the sliding device 1 in the longitudinal direction 14 of the slider 1 and / or the plate-like power transmission element 13, as best of the Fig. 2, 3rd is apparent. According to an advantageous embodiment, therefore, in addition to the actual sliding board body - Fig. 2 - The plate-like power transmission element 13 to a so-called sidecut, which is formed in particular by arcuate incisions on the longitudinal side edges of the plate-like power transmission element 13, so that in plan view of the plate-shaped power transmission element 13 results in a substantially concave outline contour. The waist or the side shape of the plate-like force transmission element 13 is running approximately the same running or substantially uniform to the sidecut or side shape of the sliding board body, as in Fig. 3 was exemplified. However, the width 47 of the plate-like force transmission element 13 is preferably chosen smaller in all longitudinal sections, as the corresponding width 14 of the sliding board body within the same or congruent longitudinal section. Preferably, therefore, the plate-like force transmission element 13 does not protrude beyond the longitudinal side edges of the sliding board body. As a result, despite a highly effective plate-like force transmission element 13, a high level of personal or injury safety of the sliding device 1 can be achieved.

In particular, can be achieved on the plate-like power transmission element 13 striking changes in driving behavior, especially regarding the sliding behavior and the inherent dynamics or the so-called "rebound" after the discharge of the sliding device 1, as occurs in particular at the corner exit, without structurally complex, costly or the weight of the ski 2 significantly increasing measures must be taken. The correspondingly altered driving behavior of such a ski 2 is clearly recognizable or noticeable even for users with average driving skills or even for users who only occasionally ski sport. Thus, the acceptance of use can be increased or the enjoyment of the use of such Schier 2 can be significantly increased.

Preferably, the plate-like force transmitting member 13 extends from the binding mounting portion toward the rear end portion as well as towards the front end portion of the sliding board body, as best shown in the drawings according to Fig. 1 and 3 is removable. This makes it possible to change the driving behavior of the sliding board body by means of the plate-like power transmission element 13 clearly or to influence significantly.

The distal ends of the force transmission element 13 are relative to the upper side 7 of the sliding board body in the longitudinal direction relatively movable, so that relative displacements between the force transmission element 13 and the sliding board body are made possible when the corresponding sliding device 1 is subjected to a sag or bending. How best Fig. 4 it can be seen, the cover layer 8 of the sliding board body is preferably designed as a plastic layer which is decorated on at least one side. This cover layer 8 forms the predominant section of the top 7 of the sliding board body. Preferably, this cover layer 8 also clad at least partial sections of the outer longitudinal side walls, as best of the Fig. 3 . 4 is apparent.

The plate-like power transmission element 13 is supported within its longitudinal extent at least in partial sections on the upper side 7 of the sliding board body load or force transmitting from. According to the illustrated embodiment, the underside of the plate-like power transmission element 13 is supported almost over the entire surface on the top side 7 of the sliding board body. Alternatively, it is also possible, on the underside of the plate-like power transmission element 13 sparsely arranged support zones relative to the top 7 of the To provide gliding board body. In this case, the support zones are positioned at least in the end portions of the power transmission element 13 such that the plate-like power transmission element 13 is at least in its end portions load or force transmitting supported on the underlying sliding board body.

To obtain advantageous effects, it is expedient if the plate-like force transmission element 13 extends over more than 50% of the length to the rear end of the gliding board body, starting from a binding mounting center point 15 provided by the manufacturer of the sliding board body, and at the same time over more than 50% of the length to extends to the front end of the sliding board body. It is advantageous if the force transmission element 13 extends in about 51% to about 96%, preferably over 66% to 86% of the projected length of the sliding board body. By projected length is meant the length of the sliding board body in top view. The longitudinal extent of the plate-like force transmission element 13 is substantially limited in that the plate-like force transmission element 13 is not intended to extend into the upwardly bent blade portion or end portion of the Gleitbrettkörpers so as not to obstruct the relative displacements between the ends of the plate-like power transmission element 13 and the Gleitbrettkörper be when this leaf-spring-like packet of force transmission element 13 and sliding board body is subjected to a downward deflection or an increase of the binding mounting portion or the central portion relative to the end portions. In particular, the upwardly curved blade portion of the gliding board body would jam against the front end of the plate-like force transmitting member 13, and dragging forces would occur if the plate-like force transmitting member 13 would extend into the blade portion of the gliding board body in a rectilinear or upwardly curved shape. In particular, when the plate-like force transmitting member 13 in about two-thirds to about nine-tenths, for example about three quarters of the length of the sliding board between the binding mounting center point 15 and the respective end of the sliding board body or with reference to the total length of Extends sliding board body, a good balance between weight optimization and stability or functionality of the entire sliding device 1 is achieved.

How best of the Fig. 1 and 3 it can be seen, the plate-like power transmission element 13 for load-transmitting support, in particular for mounting a binding device 3 provided for a user's shoe. In particular, a binding device 3 is fastened in a manner known per se on the upper side of the plate-like force transmission element 13. The binding device 3 can, as known per se, comprise a front and a heel piece, which are connected either directly or with the interposition of a guide rail arrangement with the upper side of the plate-like force transmission element 13. For connecting the jaw body or the rail arrangement of the binding device 3 with the upper side of the force transmission element 13, at least one screw means 16, 17 is provided. In particular, a sufficiently tear-resistant connection between the force transmission element 13 and the binding device 3 can be established via this at least one screw means 16, 17. The binding device 3 is thus supported with the interposition of the plate-like power transmission element 13 relative to the actual sliding board body.

How best from a synopsis of Fig. 1 and 4 It can be seen that it is expedient to carry out at least one interlocking coupling means 19, 20 between the lower side 18 of the plate-like force transmission element 13 and the upper side 7 of the gliding board body. This positive, preferably paired coupling means 19, 20 between the bottom 18 of the plate-like power transmission element 13 and the top 7 of the sliding board body extends substantially within a mounting zone for the binding device 3, as best of Fig. 1 is apparent. Within this assembly zone for a binding device 3, the board-like gliding board body has its greatest thickness or strength, as is apparent from Fig. 4 can be seen, whereby the formation of a sufficiently distinctive, mutual positive engagement between the plate-like force transmission element 13 and the sliding board body is made possible, as shown in Fig. 4 was exemplified.

The positive coupling means 19, 20 is designed such that it permits longitudinal displacements compensating relative movements between the force transmission element 13 and the sliding board body in the longitudinal direction of the sliding board body when the sliding board body and the plate-like power transmission element 13 is subjected to a deflection, as for example when driving through depressions occurs. On the other hand, the positive coupling means 19, 20 are designed such that there are relative displacements between the force transmission element 13 and the sliding board body in the transverse direction to Longitudinal extent and substantially parallel to the tread surface 10 of the sliding board body as possible prevents or such displacement tendencies increased resistance opposes. That is, the at least one positive coupling means 19, 20 permits relative displacements between the plate-like force transmission element 13 and the sliding board body in the longitudinal direction of the sliding board body, but prevents lateral deviating movements between the plate-like force transmission element 13 and the top 7 of the Gleitbrettkörpers, as these from a synopsis of Fig. 1 and 4 is clearly recognizable. This partially acting positive connection between the plate-like force transmission elements 13 and the sliding board body thus favors the most direct or delay-free transmission of forces between the force transmission element 13 and the sliding board body, without the sliding board body would be blocked in its bending behavior of the plate-like power transmission element 13.

The positive coupling means 19, 20 is preferably designed such that on the underside 18 of the force transmission element 13 at least one wart- or strip-like projection 21, 22 is formed, which engages in a corresponding or opposite recess 23, 24 in the top 7 of the sliding board body to improve the mechanical coupling between said components. The at least one, but preferably double-stranded, wart- or strip-like projection 21, 22 on the underside 18 of the power transmission element 13 may according to an advantageous embodiment but also for receiving the front portion, in particular the tip portion 25 of the screw means 16, 17 for attachment of the binding device Serve 3 on the plate-like power transmission element 13. In particular, the front end or the tip portion 25 of an anchored in the power transmission element 13 screw means 16, 17 for fixing the binding means 3 within this warzen- or strip-like projection 21, 22 on the underside 18 of the power transmission element 13. This is mainly a relatively tear-proof Anchoring the screw means 16, 17 and thus a particularly reliable or sufficiently break-proof connection of the binding device 3 or its rail arrangement relative to the plate-like force transmission element 13 achieved. The previously described screw means 16, 17, whose tip portions 25 extend into the material of the projections 21, 22, may also be provided for the attachment of guide elements, in particular of guide rails or of so-called binding plates for the jaw body of the binding device 3. It is essential that a relatively large Anchoring or Verschraubungslänge within the plate-like power transmission element 13 is present when the at least one projection 21, 22 on the underside 18 of the power transmission element 13 is advantageously used to increase the screwing depth for the screw means 16, 17, as best of Fig. 4 is apparent.

As if from a synopsis of Fig. 1 . 2 and 4 it can be seen, a profile height 26 of the at least one, preferably strip-like projection 21, 22 decreases continuously from the binding mounting center point 15 towards the rear and front end of the sliding board body and preferably runs to zero. Similarly, a receiving depth 27 of the at least one, preferably groove-like recess 23, 24 continuously decreases from the binding mounting center point 15 towards the rear and front end of the sliding board body and preferably also runs to zero. That is, the at least one recess 23, 24 and the at least one projection 21, 22 corresponding thereto leak from the binding mounting center point 15 toward the distal ends of the gliding board body and the plate-like force transmitting member 13, respectively, and terminate before the ends of the gliding board body , For example, as the distance from the binding mounting center point 15 increases, these projections 21, 22 gradually flatten over the underside 18 of the plate-like transmission element 13 and eventually completely disappear. But the projections 21, 22 and / or the corresponding recesses 23, 24 can also end in a jump. How best of the Fig. 1 and 2 it can be seen that runs at least one recess 23, 24 in the top 7 of the sliding board body in about over a third of the length of the sliding board body, it being noted that this proportion is also dependent on the respective length of the various sliding board body, ie whether a relatively short or a relatively long sliding board body is present. Conveniently, therefore, the opposite end portions of the recesses 23, 24 are flush or flush in the top 7 of the sliding board over body, as shown especially in the perspective view in Fig. 1 can be seen. The sliding board body thus has the groove-like recesses 23, 24 in its central portion, in which the sliding board body has a sufficient or comparatively large thickness or thickness. As the distance to the binding mounting center point 15, in which the gliding board body usually has the greatest thickness, the recess 23, 24 can thus have the largest receiving depth 27, while the Aufnahmetiefe 27 becomes progressively smaller with increasing approach to the end portions of the sliding board body or yourself abruptly reduced and finally preferably expires towards zero.

It is essential that the screw means 16, 17 are anchored for fixing the binding means 3 only within the plate-like power transmission element 13 and are not anchored in the sliding board body or are not screwed into the underlying sliding board body. As a result, the relative mobility between the plate-like force transmission element 13 and the gliding board body is maintained when said components are passed through or bent in relation to an axis extending transversely to their longitudinal direction. As in Fig. 4 has been shown schematically, these screw means 16, 17 for fixing the binding means 3 may also act indirectly and in particular the intermediate binding plate or a guide rail assembly for the jaw body of the binding device 3 on the plate-like power transmission element 13 set tear-off. In particular, it is advantageous if the profile height 26 of the wart- or strip-like projection 21, 22 and a plate height 28 of the plate-like force transmission element 13 is at least equal to or greater than a screw-in depth 29 of the screw means 16,17 for the determination of the binding device 3 or their components. As a result, the binding device 3 or a correspondingly required component of the binding device 3 is firmly connected exclusively to the plate-like force transmission element 13, without a direct or direct screw connection with the sliding board body.

An average height or thickness of the plate-like power transmission element 13 is between 0.5 to 3 cm. In particular, the thickness of the multilayer plate-like force transmission element 13 is between 50% and 150% of the thickness of the gliding board body within the bond mounting zone. At the in Fig. 4 illustrated, advantageous embodiment corresponds to the height or thickness of the plate-like power transmission element 13 in about the height or the thickness of the sliding board body within the same cross-sectional plane, in particular within the binding mounting zone. The total thickness or overall height of the gliding device 1 composed of the plate-type force transmission element 13 and the actual gliding board body is within the binding mounting area, as it is in Fig. 4 exemplified, maximum 5 cm, preferably 2 to 3 cm. This relatively low overall height of the gliding device 1 and its still practical strength or rigidity is achieved mainly by a multi-layer, plate-like load transfer body, in particular by the plate-like power transmission element 13, which is coupled across at least one positive coupling means 19, 20 with the actual sliding board body cross-form.

In the ready state of the sliding device 1 - Fig. 3 - Is mounted on the upper side of the plate-like power transmission element 13, a binding device 3. The screw means 16, 17 - Fig. 1 - For direct or indirect mounting of the binding device 3 are anchored exclusively in the plate-like power transmission element 13. The plate-like power transmission element 13 in turn is on the separately formed connecting means 31 within the connection zones 30 with the actual sliding board body tear-resistant - but elastically yielding - connected, as will be explained in detail below. Preferably, at a single point or within a relatively short longitudinal section, which is preferably in the region of the binding mounting center point 15, the plate-like power transmission element 13 is connected via at least one screw rigidly connected to the sliding board body, as in Fig. 1 has been illustrated schematically. In the opposite, relative to the underlying sliding board body, however, releasably mounted end portions, however, the plate-like power transmission element 13 relative to the sliding board body remains relatively movable in the longitudinal direction.

As in the Fig. 1 and 3 has been schematically illustrated, the plate-like power transmission element 13 is thus connected via a plurality of longitudinally spaced apart connecting means 31 within the corresponding connection zones 30 with the sliding board body such that a detachment or detachment of the plate-like power transmission element 13 is prevented from the top 7 of the sliding board body , In the immediate vicinity of the jaws of the binding device 3 and screw means may be provided which connect the plate-like power transmission element 13 via slots which are aligned parallel to the longitudinal direction of the power transmission element 13, with the underlying sliding board body such that different bending or chord lengths between the mentioned components can be compensated as freely as possible.

From the illustration according to the Fig. 1 It can also be clearly seen that the gliding device 1 comprises at least two components carrying the user, in particular the plate-like force transmission element 13 and the gliding board body to be arranged thereunder. The board-like sliding device 1 is thus executed at least two or more parts, wherein said components are coupled together via form-locking connections and / or screw connections.

How best from a synopsis of Fig. 1 to 3 can be seen, the plate-like power transmission element 13 is connected to or in a plurality of in the longitudinal direction of the plate-like power transmission element 13 to each other distant connection zones 30 with the sliding board body. The number of these connection zones 30 depends essentially on the overall length of the plate-like force transmission element 13 and on its strength or rigidity. In the illustrated embodiment, seven connection zones 30 are carried out, via which the plate-like power transmission element 13, which may have a length of about 80 cm to about 180 cm, depending on the length of the sliding body arranged below it, with a sliding board body adapted accordingly, ie at least slightly larger Length, is connected. Preferably, at least four connection zones 30 are provided. The individual connection zones 30 are positioned at a distance of about 15 cm to 30 cm in the longitudinal direction of the plate-like force transmission element 13. The distance between the individual connection zones 30 can also vary in the longitudinal direction of the force transmission element 13, in particular be reduced towards the end sections to a value of approximately 15 cm in order to achieve an optimized interaction between the plate-like force transmission element 13 and the gliding board body. In at least one of these connection zones 30, the plate-like force transmission element 13 and the sliding board body are connected to each other so that at least one lifting of the plate-like force transmission element 13 with respect to the upper side 7 of the sliding board body is prevented.

It is essential that within at least one connection zone 30, an elastically flexible connecting means 31 is executed, which accomplishes an elastically flexible connection between the plate-like power transmission element 13 and the sliding board body. The at least one elastically flexible connecting means 31 is designed such that it sets relative displacements between the plate-like force transmission element 13 and the sliding board body as a result of a through and / or bending of the sliding board body elastically yielding and resiliently resetting resistance. Such, elastically flexible connecting means 31 is at least in the opposite one another End portions of the plate-like power transmission element 13 is arranged, as shown in Fig. 1 was exemplified. Of course, it is also possible to perform in all connection zones 30, an elastically flexible connection means 31 for elastically resilient and resilient resetting connection between the plate-like power transmission element 13 and the sliding board body.

According to an advantageous embodiment, as in Fig. 6 By way of example, the elastically yielding connection means 31 comprises at least one elastomeric damping element 33 received in an opening 32 of the plate-like force transmission element 13. This elastomeric damping element 33 is penetrated by a fastening screw 34 for releasably secured connection between the plate-like force transmission element 13 and the gliding board body. The elastomeric damping element 33 is dimensioned such, or the fastening screw 34 is positioned relative to the damping element 33 such that with respect to the longitudinal direction of the plate-like force transmission element 13, at least in front of and behind the fastening screw 34 is a partial section of the elastomeric damping element 33. Preferably, the material of the elastomeric damping element 33 is provided around the shank of the fastening screw 34. Alternatively or in combination, however, it is also possible, with reference to the longitudinal direction of the plate-like force transmission element 13, to rest the plate-like power transmission element 13 on the left and right of the shaft of the fastening screw 34 and to support it against the shaft of the fastening screw 34 in a sliding manner. In this case, the opening 32 in the plate-like power transmission element 13 is designed as a slot 35, wherein the width of this elongated hole 35 corresponds approximately to the diameter of the shank of the fastening screw 34. The optional or combinatorial execution of an opening 32 in the plate-like power transmission element 13 in the form of a slot 35 is shown in the figures in the Fig. 3 . 5 exemplified.

How best of the Fig. 5, 6 it can be seen, a tip portion 36, ie the remote from the head of the fastening screw 34 portion of the fastening screw 34, in a threaded insert 37, in particular in a so-called insert, screwed, which is at least partially integrated in the sliding board body. The threaded insert 37 is preferably below the strength-relevant layers, in particular below the upper flange 4, positioned. Prefers an upper edge portion of the threaded insert 37 is supported on the underside of the upper flange 4 or on the underside of another reinforcing element in the layer structure of the sliding board body in a load-transmitting manner. As a result, a particularly high tear resistance is achieved for the threaded insert 37, which is at least partially integrated in the sliding board body. In the illustrated embodiment, the threaded insert 37 extends in the sliding board body into the core 6 of the sliding board body, wherein the core 6 in this case comprises a hard foam plastic, in particular polyurethane foam. However, the core 6 of the gliding board body can also comprise at least one bar profile. Preferably, two substantially parallel to the longitudinal direction of the sliding board body extending, in the sliding board body at least partially integrated hollow sections 38, 39 are formed, as shown in the Fig. 4, 5 was exemplified. The integration of threaded inserts 37 in the sliding board body, which threaded inserts 37 are positioned congruent to the connection zones 30 of the plate-like power transmission element 13, is particularly useful when the core 6 of the sliding board body of foam plastic, in particular polyurethane foam, is formed. In particular, when the core 6 materials of higher strength, such as wood, includes, such threaded inserts 37 may also be unnecessary.

Especially when the diameter of the opening 32 is relatively large or especially when the longitudinal extent of the elastomeric damping element 33 is relatively large, it is expedient to provide a pressure distribution element, in particular a washer 40, as shown in FIG Fig. 6 indicated in dashed lines. In particular, the opening 32 in the plate-like power transmission element 13 can be bridged by a washer 40 for the head of the fastening screw 34 at least in sections. As a result, fixing screws 34 can be used with standard screw head and / or apertures 32 or elastomeric damping elements 33 with relatively large extension and is still achieved by means of the washer 40 a reliable lift-off of the plate-like power transmission element 13 relative to the top 7 of Gleitbrettkörpers.

The embodiments show possible embodiments of the board-like sliding device 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this Variability due to the teaching of technical action by the subject invention in the skill of those working in this technical field is the expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiments, of the scope of protection.

For the sake of order, it should finally be pointed out that for a better understanding of the structure of the gliding board body, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.
