Description

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

In the EP 1 297 869 A1 is a Schneegleitbrett, in particular a ski, and a spreading device for the sliding board body described. The sliding board body is at least over a partial length by this spreader in its width variable. The spreading causes this spreading of the sliding board body in response to the load or bending of the sliding board body. This spreading device consists of a plurality of paired expansion levers, which cause a spreading of the sliding board body in the region of a slot in the rear end of the ski. The load-dependent wider and narrower slit is thus provided at a rear end of the sliding board body. Upon actuation of the spreading device in the sense of a reduction or enlargement of the enclosed between two expansion levers angle spreading of the rear end of the sliding board body is effected. According to a further embodiment, an actuator may be formed, via which the expansion element of the spreading device can be preset. In the proposed embodiments, the rear end of the sliding board body is slit and integrated within the slot or the corresponding recess, which occupies about one third of the width of the ski width, the spreading device. The touched spreading is structurally relatively expensive and achievable with the prior art modification of the driving or cornering behavior of the sliding board body is only clearly visible if the rear end of the sliding board body is subjected to a relatively strong, elastic spreading. In order to obtain striking changes in the geometry or the driving behavior of the sliding board body, so strong deformations or elastic spreads of the rear end are required, whereby the forces acting on the sliding board body loads can quickly take an unfavorable high degree or due to low actuating forces for the spreading the desired extent of the changes in driving behavior is relatively difficult to achieve.

The WO 02/070086 A1 describes a gliding device, which is formed by two independently constructed sliding board body. The two sliding board bodies are coupled to each other by means of a connecting mechanism such that due to a change in inclination a podium-like ridge level for a sports shoe between the two Gleitbrettkörpern a height offset occurs. In addition, such an inclination or weight shift of the user changes the angle of the control edges of the individual sliding board body with respect to the ground. As a result, the mountain-side control edges of both sliding board body interact with the ground. The connecting mechanism between the sliding board bodies is formed by a plurality of bridge elements which are spaced apart from one another in the longitudinal direction and which are coupled by means of a rod-like connecting element. The individual bridge elements are formed by Parallelogrammhebelanordnungen, with which a hinged movement coupling between the two sliding board bodies and the inclination variable Aufstandsplattform is created. Such coupling mechanisms cause a relatively high level of support for the user against the ground, resulting in an increased risk of injury. Such a ski skateboard is also problematic in terms of high speeds and narrow or steep slopes. In addition, these structures, which are also known as "swingbo", are complex in terms of production technology and not very suitable for practical use.

The EP 0 279 648 A2 describes a board-type slider for use on a snow ground, which is slotted continuously from the binding mounting portion toward the rear end portion of the sliding board body so that a left and right supporting portion for the user of the slider is formed with respect to the longitudinal direction of the board-like slider. The left and right supporting portion of the sliding board body are torsionally flexible to each other, so that during use of the sliding board body, that is, during a use-related load of the individual support sections, the mountain side edges of the two support sections can each engage in the snow background. The two engaged side edges of the two support sections act in such a way that the board is directed in a substantially same direction. By in the driving or load state each torsionally flexible and mutually offset in height, left and right support portion of the sliding board body so a double edge engagement with respect to the snow background is possible and thus co-determined the radius of curvature. Also this design is not practical or difficult to control and requires increased skill when driving on steep slopes or when driving at high speeds.

The US 4,449,735 A describes a board-like sliding device comprising a pair of mutually parallel, elongated sliding board parts. In the longitudinal center region of these sliding board parts, a binding mounting platform is designed to support the foot of a user. The binding mounting platform is part of a coupling mechanism, which articulates the two parallel, independently trained sliding board body, so that between the left and right Gleitbrettteil a vertical displacement in the vertical direction is allowed to its treads when running on a slope skewed. Due to the height variability between the two gliding board bodies coupled together, the mountain-side control edges of each gliding board part are in contact with the snow background during such oblique movements. This design is due to the required longitudinal and transverse connections between the individual Gleitbrettteilen structurally complex, costly and not very practical.

The EP 0 490 044 A1 describes a ski having a lower gliding board body and an elongated stiffening element attached to the upper side thereof, which is coupled to the upper surface of the gliding board body by a flexible or 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 according to a first embodiment as a multilayer sandwich construction, which is connected to the top of the sliding board body via an elastically resilient 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. A change in the waist or cross-sectional shape of the lower sliding board body is not possible in this prior art embodiment.

The EP 0 542 123 A1 and the EP 474 967 A1 describe elastically resilient retaining devices for ski bindings. In this case, an anchoring plate is integrated in the ski, which is elastically resiliently held against the top of the ski. The binding device or its guide rail arrangement is screwed to this integrated in the ski structure, elastically yielding anchoring plate. As a result, an elastic mounting of the binding device or its jaw body relative to the ski body is accomplished. A sliding board body with a variable or variable cross-sectional shape or sidecut is not provided.

The US 5,820,154 A describes a board-like sliding device, which comprises a lower sliding board body and an elongated force transmission element supported on its upper side. The upper force transmission element, on which the ski binding is mounted, is thereby supported over a plurality of elastically yielding layers and over at least one comparatively pressure-resistant layer opposite the upper side of the sliding board body. Measures for changing the cross-sectional shape or the waist of the sliding board body are not to be found in this document.

The FR 2 815 879 A1 describes a ski with at least one attached to the top plate for individually adjustable change in the bias in the upper flange of the ski body. As a result, for example, in the blade region of the ski body, a tendency to buckling can be created or a tendency to transverse curvature can be set transversely to the ski direction. The respective changes in the characteristics of the sliding board body are only marginal and hardly noticeable to an average user of the sliding board body during driving. In particular, the variability of the driving behavior is not very satisfactory.

The EP 0 034 643 A1 describes a ski, which in the direction of travel related rear end portion has a wedge-shaped in plan view incision, so that the sliding board body has a dovetail-shaped end portion. Measures to influence the waist of the sliding board body are not to be found in this document.

The DE 38 03 483 A1 relates to a method of making a ski and a ski made by this method. This document describes a standard manufacturing process. Measures for influencing the geometry of the ski body as a function of the load and / or with respect to a manual variability can not be found in this document.

The DE 32 00 383 A1 describes a ski whose blade section has several longitudinal sections. As a result, the ski is torsionally softer in the blade area with respect to its longitudinal axis executed. Measures for a load-dependent variable or manually changeable sidecut of the sliding board body can not be found in this document.

The AT 238 074 B describes a ski whose front or rear section consists of two juxtaposed ski body sections separated by at least one vertical slot running in the longitudinal direction of the ski. The width of the vertical slots is smaller than the width of the individual, separate body sections. The length of the vertical slots starting from the ski tip or from the Schihinterende to the first cross-connection between the ski body sections is about one third of the total ski length. By these measures arise in the front section and in the rear section adjacent and in the vertical direction against each other movable end portions of the ski body. The at least one vertical slot thus reduces the torsional stiffness of the respective end portion of the ski body, so that the separated by the vertical slots end portions of the ski body can also easily pivot. This is to facilitate sliding, especially when driving on a slope, and also facilitate directional changes. A change in the sidecut is not possible in this prior art Gleitbrettkörper.

The US 4,565,386 describes a ski which has along its longitudinal center a slot which ends immediately in front of the ski tip and the rear end of the ski body. This partial longitudinal slot in the ski body allows the formation of a vertical offset between the left and the right section of the ski body. This is to be made possible for oblique rides on a slope a double edge grip, in particular in each case an edge grip by the two sections of the ski body. However, a variable or variable waist is not provided in this ski.

The DE 43 24 871 A1 describes a sliding board body, which can be composed of three structurally independent, board-like elements. In particular, a sliding board, in particular a snowboard, is assembled from a total of two skis and a center section arranged therebetween, as well as using fitting parts. In the middle section of the sliding board, a tensioning means is arranged, with the aid of which the laterally arranged to the middle part Schier can be stretched under elastic deformation in their transverse direction against each other, so that the desired waist radius of the sliding board can be adjusted. If the two outer skis are tensioned to each other by means of the clamping means, the gap will become smaller and smaller with increasing deformation of the ski in the transverse direction, until it completely disappears at the middle part when the two skis fully engage. As a result of this tension and deformation of the skis, the fully assembled gliding board or snowboard ultimately has sidecut wheels which are substantially smaller than those of the skis. The disadvantage here is that the handling of this sliding board is complex and the necessary components, in particular the fitting parts, are mechanically complex and significantly increase the overall weight of the sliding board body.

The DE 34 44 345 A1 describes a so-called Doppelkufenschi, in which two skids of a ski parallel to each other and are bent at the two ends connected to each other upwards. However, it is also possible for several, in particular three or four runners per run to run parallel to one another and to be connected at their opposite ends to form one unit. The longitudinally extending slot between the double skids should drain accumulated snow before the tip of a ski better. Rounded inner edges of the two skids to ensure easier rotation and maneuverability of the ski. However, the proposed embodiments have only a limited practicality.

The DE 85 12 315 U1 describes a ski whose rear portion is divided by a slot. The width of the slot is reduced by means of an adjustment and enlarged, so that the rear portion of the ski is variable with respect to its side edge course. Although the slit of the rear end of the ski allows changes in Schigeometrie, but the extent of the changes is only partially satisfactory, considering that the elastic spreadability of the back Schieses is subject to structural restrictions.

The DE 84 22 316 U1 describes a ski whose front and rear portions have longitudinal slots extending forwardly and rearwardly from the binding mounting portion and stopping short of the respective end of the ski, so that one-piece transverse stable ski ends are formed respectively. By means of each associated adjustment elements, the width of the slots can be changed such that an independent change of the side edge profiles in the front and rear portion of the Schis is possible. The disadvantage here is that the geometries that can be set with this structure lead relatively soon to inhomogeneous or non-uniform progressions of the side edges, so that the control behavior of the ski suffers. In particular, the so-called "driving on the edge", which is important for the dynamics or acceleration of the ski at the exit of the curve, is made more difficult, as a result of which disadvantageously disadvantageous slip phases can occur during cornering.

The DE 24 17 156 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 FR 2 794 374 A1 discloses various variants for changing the geometry, in particular the side edge profile of a ski. According to one of the proposed embodiments, both ends of the ski may be provided with slots which extend beyond the ends of the ski so as to result in longitudinal cuts in the opposite ends of the ski. Close to the front and rear ends of the ski mechanically coupled or independently acting adjustment means are provided which allow a narrowing or spreading of the respective ends of the ski. Although the driving characteristics of the ski can be significantly influenced with these measures, the performance achievable with such a sliding device is not very satisfactory.

The EP 1 516 652 A1 describes a snow sliding board, in particular a snowboard, which has at least one of its ends a recess into which an insert is inserted. This insert is shaped such that it forms on its underside at least one trough or depression, which is open to the underside of the sliding board body. The insert is formed from a permanently deformable material, in particular from a thermoplastic polymer or plastic, permanently in a curved, over the top of the sliding board body protruding form is deformed while the snow sliding board is produced. With these depressions or recesses in the running surface of the snow gliding board, the flow of the snow or the gliding in the snow should be positively influenced. Especially in powder snow, an improved guide for the snowboard and a reduced resistance in the rear blade area should be set. In particular, improved deep snow properties are to be achieved for a snowboard. An individual change in the guiding properties, in particular the cornering behavior of the snow gliding board, however, is not possible via the insert part of permanently formed thermoplastic material inserted into the recess.

The DE 201 13 739 U1 describes a snowboard having substantially along its central axis a slot which extends from the rear end of the sliding board body at least to its central portion and thus forms two separate, rear legs, which are interconnected by the one-piece, front portion. This slot extends tapering from back to front in a substantially wedge-shaped manner, the slot being wider in the rear section of the snowboard than in the middle section of the snowboard. In addition, this slot can pass into a depression that runs smoothly towards the front section of the snowboard. Further, an adjusting device is provided which acts on the two legs of the snowboard and is designed as a threaded spindle assembly. Thus, the distance between the two legs is adjustable both in the pulling direction, ie in the manner of a narrowing of the slot, as well as in the printing direction, ie in the manner of widening of the slot. Consequently, the sidecut and thus the handling of the snowboard can be changed individually to a certain extent. The disadvantage here is that the slot in the sliding board body, which extends from the rear end over more than half the total length of the sliding board, forms two legs, which extend over vast sections independently of each other and are therefore exposed to high loads. In particular, the edge grip or steering stability of such an embodiment is only partially satisfactory, after acting on the relatively narrow legs of the snowboard during cornering high torsional loads that can cause a relatively strong distortion of the leg about its longitudinal axis. In particular, when corresponding edge loads occur, as is often the case, especially with cut turns, the stability or likelihood desired by the user is difficult to fulfill.

The DE 41 30 110 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 having a body composed of a plurality of elements, which has a running surface on its underside and a region for fastening a binding on its upper side. 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. The achievable driving dynamics or with this training achievable driving pleasure, however, is still not satisfactory enough 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 elongated, flat component, which is bent at intervals about substantially parallel, transverse to the longitudinal direction of the ski axis extending 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. A disadvantage is that the arcuate intermediate carrier and the connecting joint assemblies increase the complexity of the structure, whereby the total weight of a such 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. These constructions are intended to give a ski which is as adaptable as possible to various terrain forms by having a high degree of flexibility and the lowest possible torsional rigidity. 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 present invention has for its object to provide a ski or a snowboard, which or which has manually variable properties and / or load-dependent variable driving characteristics, the achievable with such Gleitbrettkörper use performance should be as high as possible. In particular, an improved cornering behavior of a variable in its side edge geometry or sidecut ski or snowboard is to 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 inventive, geometrically variable ski or the inventive, geometrically variable snowboard in terms of its driving characteristics compared to the known from the prior art geometry variable, board-like glides offers significant advantages. In this case, a static presetting of the respective desired geometry of the sliding board body depending on the individual wishes of the user and / or a dynamic change in the geometry of the sliding board body during its use is possible, whereby the sliding board body improved Has agility. In addition, an interesting driving behavior or a varied range of applications is opened with a structure as simple as possible and long-term functionally reliable means, whereby the user can have increased joy or increased enjoyment of the use of the sliding device according to the invention. In particular, a ski or snowboard is created, the side edge geometry - and thus its driving behavior - depending on the loads occurring and / or depending on the individual preferences relatively distinctive variable or changeable, the claimed winter sports equipment still achieve excellent edge grip and steering stability , which is especially important when driving through curves or for an exact swing triggering 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 slider during a swing phase, the sliding board body in contact with the ground unexpectedly yields or virtually kinks and suddenly a difficult to control behavior of the board-like slider 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 power transmission element thus stabilizes the sections by the slit in its strength or rigidity sections markedly modified sliding board such that good controllability and a favorable leadership behavior can be achieved and yet a relatively far-reaching or pronounced change in the sidecut, ie the Side shape of the sliding board body is possible. In particular, the plate-like force-transmitting element prevents the sliding board tongues lying on both sides of the slot from deviating to an unfavorable extent in the vertical direction from the running surface covering. On the other hand, the plate-like force transmission element at least does not obstruct the desired approach or distancing between the sliding board tongues located on either side of the slot and even supports and / or accomplishes this by the plate-like force transmission element, thus actively influencing the guiding behavior or the extent of the change in direction adjusted if the sidecut of the ski or snowboard is influenced by the corresponding geometry influencing means depending on the load.

By the measures according to claim 2, the stabilization and at the same time geometry influencing 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. the geometry-influencing and stabilizing effect of the plate-like force transmission element is provided to a high degree with respect to the gliding board body without the need for structurally complex measures.

The embodiment according to claim 3 provides the advantage that the force transmission element can act with high efficiency on the sliding board body after the force transmission element extends over extensive sections of the sliding board body. In particular, such a force transmission element acts on the gliding board body near the end sections of the gliding board body, which on the one hand accomplishes a good stabilizing function and on the other hand sufficiently marked variability of the cross-sectional shape, in particular the cross-sectional width, of the gliding board body in at least one of its end sections.

Also advantageous is the measure according to claim 4, since thereby the forces applied by the user or initiated by the user control movements can be initiated with the interposition of the force transmission element in those sections of the sliding board body, in which the force transmission element most or best effect against the Sliding board body can unfold.

Another advantage is an embodiment according to claim 5, 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.

Of particular advantage is also an embodiment according to claim 6. By this construction is achieved that an increased depth of engagement or a higher effective thread length for the screw-like fastening means of the binding device is available, whereby a high pull-out strength is achieved for the screw-like fastening means. 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 7 offer the advantage that, despite relatively thin executable plate height of the plate-like power transmission element, a high pull-out strength 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 8, 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 sliding board body, the additionally required connecting elements between said components, in particular fastening screws, dimensioned weaker and / or reduced in number and / or optimized in their positioning.

Also advantageous are the measures according to claim 9, since characterized 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 high torsional stability between the plate-like power transmission element and the Gleitbrettkörper, with reference to an axis extending vertically to the tread surface, is achieved.

In the measures according to claim 10 is of advantage 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 11, 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 power transmission element relative to the sliding board body a can travel correspondingly wide Relatiwerschiebungsweg when the sliding board body and the plate-like power transmission element is subjected to an 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, after it is influenced as little as possible, especially in the assembly zone for a binding device in its bending behavior of the plate-like power transmission element, so that a harmonious, uniform bending characteristic can be achieved. By the measures according to claim 10, a package of board-like or plate-like elements is virtually created, which permits longitudinal relative movements between the underside of the plate-like power transmission element and the top of the sliding board body, when the overall construction of an arcuate, elastic deflection is subjected. 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.

A particularly robust and structurally advantageous embodiment of a geometry influencing means is specified in claims 12 and 13, respectively. In particular, high actuating forces can thus be transmitted between the geometry-influencing means or the plate-like force transmission element and the gliding board body, without the need for particularly expensive or expensive modifications to the ski or snowboard.

In the embodiment according to claim 14, it is advantageous that a robust geometry-influencing means which can be constructed as inexpensively as possible is created, which additionally allows a high range of action with regard to a change in the cross-sectional geometry or side shape of the gliding board body. In particular, a conversion of a longitudinal movement is achieved in proportionate transverse movements in a simple and reliable manner, this configuration remains functionally stable and functionally reliable even under the usually existing, relatively harsh operating conditions of the gliding device, especially the winter sports equipment.

In the embodiment according to claim 15 is advantageous that a so-called sandwich-compound element is created, which acts as a plate-like power transmission element. In particular, a construction method is used, which has proven itself in the production of board-like gliding equipment, especially winter sports equipment, many times and many years. Above all, this creates a particularly stable and the requirements of the best possible fair, plate-like power transmission element whose production costs can be kept as low as possible, after the producers of the Gleitgerätes already existing, mechanical equipment and materials used to create the plate-like power transmission element or used can be. In addition, this plate-like crane transmission elements can be created, which have a good balance between strength and light weight. Of particular advantage is further that thereby the plate-like power transmission element can take over part of the required static total strength ideal, so that the underlying sliding board body can be dimensioned correspondingly weaker in its structure without problems in terms of robustness or everyday practicality of the entire sliding device occur.

The measures according to claim 16, a plate-like power transmission element is created, which meets the respective technical requirements in a favorable manner. In particular, such a force transmission element can easily withstand the occurring loads or can be used to transmit or absorb the required forces with high reliability. In addition, such a plate-like power transmission element can be made relatively lightweight yet sufficiently stable. Another significant advantage is that the components required for the construction of conventional skis or snowboards also be used for the plate-like power transmission element, whereby the most cost-effective production can be achieved. This production cost advantage is also reinforced by the fact that the machines required for the production of conventional skis or snowboards can also be used to produce the plate-like force transmission element, so that increased efficiency can be achieved for the manufacturer of a sliding device according to the invention. In addition, the know-how already available for the production of skis or snowboards can also be used to create high-quality, plate-like crane transmission elements. Another significant advantage is that a visually appealing or advantageous appearance of the sliding device can be achieved after the plate-like power transmission element and the actual gliding board body can form a visually or designerisch relatively homogeneous unit. In particular, those decorative methods or decoration options are also applicable to the plate-like power transmission element, which are already used for conventional skis or snowboards in a proven manner. In particular, the appearance of the plate-like force-transmitting element can be ideally matched to the appearance of the underlying sliding board body to be combined therewith. Thus, on the one hand, a good or harmonious appearance and, in addition, a technical production simplification is achieved which, among other things, has an improved economic efficiency.

A power transmission element which is particularly suited to the strength, design and economic requirements is achieved by the measures according to claim 17.

By the measures according to claim 18 as unimpeded longitudinal compensation between the plate-like power transmission element and the gliding board body is achieved, which can better achieve an improved bending behavior, in particular an ideal bending characteristic of the overall construction. In addition, such longitudinal compensation movements can be implemented as effectively as possible in movements or actuating forces for changing the cross-sectional shape of the sliding board body. In addition, abrasion or scratch marks can thereby be avoided, so that a long-term attractive appearance of the ski or snowboard in the region of Relativverschiebungszonen between the force transmission element and the sliding board body is achieved.

By the measures according to claim 19 is achieved in an advantageous manner that the achievable with the ski or snowboard invention performance or the achievable driving behavior is significantly improved or kept high. In particular, the tracking or the controllability of the specified ski or snowboard can be significantly improved or positively influenced. In addition, on the one hand a sufficiently distinctive cross-sectional variability can be achieved and still good leadership quality, especially tracking stability, and a predictable cornering behavior for the

Users of the specified sliding device are guaranteed.

The embodiment according to claim 20 has the advantage that a good compromise between a sufficiently distinctive variability of the cross section or the side shape of the sliding device and a sufficient stability to achieve a good driving or cornering behavior is guaranteed. In particular, a ski designed in this way or a geometrically variable snowboard designed in this way has high practical suitability.

Finally, the measures according to claim 21 are advantageous, since a substantially X-shaped in plan view, bilaterally split sliding board body is created, the driving or cornering behavior is also sufficiently markedly changeable or variable, if the two ends only one be subjected to relatively small geometry influence or spreading. In particular, this makes it possible to bring about relatively marked cross-sectional or side-form changes with low loads on the face-side sliding board tongues of the sliding board body. By this configuration, therefore, the material or material loads of Gleitbrettkörpers can be kept relatively low and is for the user nevertheless a sufficiently noticeable change in the driving or. Curve behavior achievable.

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 throughout the description are transmitted mutatis mutandis to the same parts with the same reference numerals or component names can. Also, the position information selected 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 to the new situation. Furthermore, individual features or combinations of features from the illustrated and described, different embodiments may represent for themselves, inventive or inventive solutions.

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 6 is a preferred embodiment of a board-like sliding device 1 with load-dependent varying geometry shown. In particular, a ski 2 is shown schematically, whose cross-sectional geometry or waisting varies depending on the load occurring when edge up on the lateral control edges, in which only the most essential components are exemplified. In addition, only the most essential sub-components, in particular the sliding board base body and the means for influencing the geometry of the sliding board body 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 connected to each other and together form the one-piece main body of the sliding device 1. In known manner, these form Layers 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 is firmly connected over its entire, the core 6 facing flat side with the Gleitgeräteaufbau, in particular with 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 by the materials and layer thicknesses used and by the methods of connection used. It is essential that the indicated, board-like sliding device 1 comprises at least one geometry influencing means 19, which allows a load-dependent variable and / or a manually variable, in particular a presettable cross-sectional geometry or sidecut of the sliding device 1. Under sidecut is the so-called "sidecut" or side edge radius of the sliding device 1 to understand. The structurally predefined waisting of the sliding device 1 thus results in a width 13 of the sliding device 1 which varies in the longitudinal direction of the sliding device 1.

The geometry influencing means 19 of the sliding device 1 comprises reference to the width 13 of the sliding device 1 at least in the central portion of the sliding device 1 at least one slot 14. This slot 14 in the sliding board body extends with respect to its longitudinal extent in the longitudinal direction of the sliding device 1 and with respect to its depth direction - arrow 15 - starting from the top 7 of the sliding device 1 in the direction of the tread surface 10. With respect to its longitudinal direction, the at least one slot 14 extends substantially parallel to the longitudinal direction of the sliding device 1, as best of all Fig. 1 is apparent. The at least one slot 14 along the longitudinal middle section of the ski 2 is dimensioned and designed such that a cross-sectional weakening of the sliding device 1 is effected and in particular the rigidity or dimensional stability of the sliding device 1 is reduced transversely to its longitudinal direction.

How best Fig. 1 it can be seen, the slot 14 is formed at least in the front portion, ie in the partial section between the binding device 3 and the front end of the sliding device 1. Preferably, such a slot 14 is also executed in the rear portion of the sliding device 1, ie in the section between the binding device 3 and the rear end of the sliding device 1. Alternatively, the at least one slot 14 may also extend over the binding mounting portion of the sliding device 1, ie extend continuously from the front end of the sliding device 1 in the direction of the rear end of the sliding device 1. In this case, this slot 14 extends in the region of the longitudinal central portion of the sliding device 1, in particular in its binding mounting portion, only over a portion of the cross-sectional height of the sliding device 1, so that it is executed in the binding mounting portion in the manner of a groove.

The formed in at least one end portion, preferably in both end portions of the sliding device 1 slot 14 penetrates in at least one of the end portions of the sliding device 1 all strength or stiffness relevant components of Gleitbrettkörpers or Gleitgerätes 1. That is, the at least one slot 14 in at least one the end portions of the slider 1 forms a split end portion of the slider 1.

Thus, the slot 14 defines at least one dovetail-shaped end portion on at least one end of the slider 1. This slit of the front and / or rear end of the gliding board body results in at least first and second sliding board tongues 16, 17 per end portion of the slider 1. The first and second sliding board tongue 16, 17 are substantially independent of each other relatively movable. That is to say that the first sliding board tongue 16 is largely decoupled relative to the second sliding board tongue 17 in static or mechanical terms, if one considers only the actual sliding board body, as in FIG Fig. 2 is exemplified. This mechanical decoupling is accomplished by the slot 14 located between the first and second sliding board tongues 16, 17, which extends from at least one of the outermost ends of the sliding device 1 in the direction of the longitudinal center of the sliding device 1. In particular, the slot 14 cuts through at least one end portion of the slider 1 completely, ie within its entire cross-sectional height, the slot 14 also extends to the extreme end of the slider 1, so that the previously defined, dovetail-shaped end portion of the slider 1, in particular the ski 2 is formed ,

From the representations according to the Fig. 5, 6 It can be clearly seen that the at least one slot 14 subdivides the upper belt 4, which is relevant with regard to the statics or strength of the sliding device 1, into a first or left and a second or right upper belt strand 4a and 4b substantially within the longitudinal extent of the slot 14 or separates. That is, the upper belt 4 is interrupted or severed due to the formation of the slot 14 substantially within the longitudinal portion of the slot 14 and is divided into at least two Obergurtstränge 4a, 4b. The same applies to the lower flange 5, which is at least within the longitudinal portion of the slot 14 also divided into a first and left and in a second or right Untergurtstrang 5a and 5b or separated. The strength-relevant upper flange 4 and also the strength-relevant lower flange 5 are thus interrupted or split by means of the longitudinal slot 14, so that the sliding device 1 in its transverse rigidity is substantially reduced and in particular an adjustment of the thus formed sliding board tongues 16, 17 is made possible relative to each other when the sliding device 1 or the ski 2 is exposed to corresponding edge loads and / or if a corresponding geometry influencing means 19, for example, a manually presettable actuating means , in particular a spreading means 20, is used.

In order to be able to effect a corresponding, elastic cross-sectional deformation, in particular a stretching or widening of the cross-sectional width transversely to the longitudinal direction of the sliding device 1 and essentially in a parallel plane to its tread surface 10 under real operating conditions or loads of the sliding device 1, the slot 14 extends or extending in the longitudinal direction of the slider 1 juxtaposed slots 14 over 40 to 80%, preferably over about 60% of the length of the sliding device 1. Regardless or in combination thereto, which formed at the front end of the sliding board body slot 14 extends over 50% to 90%, preferably over about 75% of the portion between the binding device 3 and the front end of the sliding device. 1

It is particularly advantageous if the slot 14 extends into the front blade section of the ski 2 and is therefore also formed in the blade section, as shown in FIG Fig. 1 is shown by way of example. In particular, it is favorable if the slot 14 extends continuously within the front blade section to the front end of the ski tip. The upwardly curved blade section, which has a relatively high transverse rigidity as a result of this curvature, is thereby decisively influenced in terms of its torsional rigidity, whereby the necessary stability requirements can be fulfilled by such a ski 2 with at least one split end section on the one hand and the desired ones on the other hand , elastic deformations can occur. These elastic deformations can be generated by the bending loads occurring during use on the ski 2 or be achieved under the action of restoring forces of an individually adjustable actuating means. On average, changes in the effective curve radius of the ski 2 of up to 6 m can be achieved by the respective cross-sectional influencing means 19. In particular, this allows a change in the waist radius of the ski 2 in the range of several meters can be achieved without structurally complex, costly or the weight of the ski 2 significantly increasing measures must be taken. Such adjustment for the effective radius of curvature, with a such Schi 2 using its control edges 11, 12 can be pulled on a corresponding surface of snow, it is clearly recognizable or noticeable even for users with average driving skills or for users who operate only occasionally skiing. Thus, the acceptance of use can be increased or the enjoyment of the use of such Schier 2 can be significantly increased.

Preferably, a width 18 of the slot 14, starting from the upper side 7 of the sliding device 1, decreases in the direction of the tread surface 10. That is, the slot 14 in cross-sectional view is preferably wedge-shaped in the direction of the tread surface 10, wherein the largest width 18 is formed in the transition region to the top 7 of the sliding device 1.

As the representations according to Fig. 1 3 to 6, the board-type sliding device 1 comprises at least one geometry-influencing means 19, which is designed to be able to change or influence the cross-sectional geometry of the sliding device 1 in at least one of the end sections of the sliding device 1. In the embodiment shown, a spreading means 20 is formed as a geometry influencing means 19 which, depending on the load-dependent deflection of the sliding device 1, a variation of the width 18 of the slot 14 and thus a load-dependent change of the sidecut or the width 13 of the sliding device 1 within the longitudinal extent of Slot 14 causes. The spreading means 20 is formed such that the two sliding board tongues 16, 17 are spread apart transversely to the longitudinal direction of the slider 1 and substantially parallel to the tread surface 10 when the slider 1 is subjected to a deflection, as is especially when cornering with the Sliding device 1, in particular during so-called "carving" occurs. The stronger the slider 1 is deflected, the wider the slot 14 opens or the larger is a spread angle 21 between the longitudinal center axes of the two mutually adjacent sliding board tongues 16, 17. The spreading means 20 widened so at least one end portion of the sliding device 1, if an elastic bending of the corresponding end portion of the sliding device 1 about a transverse axis of the sliding device 1 takes place, as shown in particular from the illustrations of the geometry influencing means 19 according to the Fig. 1 and 3 is clearly recognizable.

It is favorable that the at least one slot 14, which the strength-relevant components or layers and layers of the sliding device 1 severed in at least one end portion of the sliding device 1 and thus two substantially parallel sliding board tongues 16, 17 formed in at least one of the end portions of the sliding device 1 is provided with an elastically stretchable bridging element 22 or. This elastically stretchable bridging element 22 is preferably formed by a one-piece, elastically extensible and recoverable plastic layer 23, so that a wide-variable bridging element 22 between the two sliding board tongues 16, 17 is formed. In particular, the elastically extensible bridging element 22 is elastically stretchable and recoverable at least transversely to the longitudinal extent of the slot 14 or of the sliding device 1. The elastic extensibility and resiliency of the bridging element 22 can be accomplished by the plastic layer 23 inherent elasticity properties and / or by the shape, in particular the cross-sectional shape of the bridging element 22. In particular, the bridging element 22 or the plastic layer 23 can have at least one expansion fold 24 or similar shapes which are suitable for width variation, such as, for example, a fold-like deflection, an arched bulge or the like.

The bridging element 22 is also designed such that it prevents a passage or a transfer of snow within the slot 14, starting from the tread 10 toward the top 7 of the sliding device 1. Thus, the bridging element 22 fulfills the function of a barrier layer which can be stretched and restored elastically at least in the transverse direction and which also prevents a passage or a transfer of snow or ice between the lower side 9 and the upper side 7 of the sliding device 1 and vice versa. The bridging element 22 may represent an elastically stretchable intermediate piece of the tread surface 10, as this especially from the Fig. 5, 6 is apparent.

The bridging element 22 for the slot 14 in the tread 10 or in the sliding device 1 thus has a with respect to its cross-sectional shape reversibly changeable, in particular elastically stretchable and recoverable expansion section 25. With sufficiently high elasticity of the bridging element 22, in particular when forming an elastomeric or rubber-like plastic layer 23, it is possible to form a plate-like or planar plastic layer 23 between the two sliding board tongues 16, 17.

Preferably, the bridging element 22 is mainly in terms of its cross-sectional shape reversibly changeable, in particular expandable and compressible. For this purpose, the bridging element 22 may have the previously indicated expansion fold 24. For example, the shape-variable cross-section or expansion section 25 may be formed by at least one arcuate deflection 26 in the cross-sectional profile of the bridging element 22. In particular, this expansion section 25 may be formed by an indentation or bulge in the cross-sectional profile of the bridging element 22, as best shown in FIGS Fig. 5 to 9 is apparent. A crest line 27 or an apex of the loop-shaped or arcuate deflection 26 or the dome-shaped deformation of the bridging element 22 lies in a cross-sectional view above a sliding surface of the tread surface 10 formed by the underside 9. The cross section of the bridging element 22 is preferably chosen such that within the longitudinal extension of the bridging element 22, at least one recess 28 extending essentially parallel to the longitudinal central axis of the sliding device 1 is formed. This recess 28 is formed in the bottom 9 of the slider 1 and thus extends, starting from the sliding surface on the bottom 9 of the tread 10 at least partially toward the top 7 of the slider. 1

How best of the Fig. 5, 6 it can be seen, the bridging element 22 preferably has two in the longitudinal direction of the sliding device 1 extending, in cross-sectional view dome-shaped upwardly facing and substantially parallel to each other, loop-shaped deflections 26. The bridging element 22 may be formed from any material that is as tear-resistant and elastically deformable as possible. Preferably, the bridging element 22 is formed from a strip-shaped plastic layer 23, in particular from an elastomeric plastic, wherein the bridging element 22 is preferably produced by means of an injection molding process and thereby obtains the desired profiling or cross-sectional shape. Optionally, the bridging element 22 may also be formed from a non-molded plastic, in particular from a textile material. Such a textile or woven material is preferably provided with a coating, in particular of an elastomeric plastic.

A thickness 29 of the bridging element 22 preferably corresponds approximately to a thickness 30 of the tread surface 10. Accordingly, a thickness 29 of the bridging element 22 is expediently between 0.1 mm to 2 mm, in particular the thickness 29 of the bridging element 22 in about 1 mm.

The bridging element 22 should, in addition to corresponding elasticity properties, also be designed to be as puncture-resistant or tear-resistant as possible. In particular, the bridging element 22 is designed to be so robust or tear-resistant that when the tip of a conventional ski pole is supported on the bridging element 22 and the ski pole is loaded with the torso of a person, the bridging element 22 is not perforated. Preferably, the bridging element 22 is designed so robust or abrasion resistant that at least five winter seasons with average frequency of use of Gleitbrettkörpers due to the friction movements against snow or ice do not lead to such wear or wear phenomena that the performance of Gleitbrettkörpers would be impaired. The tear strength of the bridging element 22 is preferably chosen such that a stone lying loosely on a corresponding ski slope can not lead to the tearing or tearing of the bridging element 22 when the sliding board body, in particular the ski 2, slides over a corresponding stone.

At least the underside of the bridging element 22 facing the substrate of the gliding board body can be provided with a coating which reduces the sliding friction or with a coating which increases the sliding ability with respect to snow or ice. This frictional resistance to snow or ice reducing coating of the bridging element 22 may be formed by a layer of Teflon, sliding wax or similar, the sliding friction reducing substances.

The bridging element 22 which can be stretched and restored elastically at least in its transverse direction can also be formed by a layer consisting of several components. In particular, the bridging element 22 can have at least one reinforcement layer and at least one cover layer. The bridging element 22 can also be made transparent or colored diffusely or translucently. The bridging element 22 can be produced by means of a multi-component injection molding process in order to obtain the desired spatial profiling and / or, for example, to form zones with different strength and / or elasticity properties. The bridging element 22 can thereby also have color-contrasting zones in a simple manner.

The bridging element 22 is designed at least in its lateral edge portions 33, 34 such that a high-strength, adhesive or thermoplastic welded connection with the adjacent layers or layers of the sliding board body is achieved.

How best from the Fig. 5, 6 it can be seen, the bridging element 22 is preferably designed as a structurally independent component. This bridging element 22 is connected via its lateral edge portions 33, 34, which extend substantially parallel to lateral boundary edges 31, 32 of the slot 14, with the two sliding board tongues 16, 17. In particular, lateral edge sections 33, 34 of the bridging element 24 close as gap-free as possible to side edges 35, 36 of the tread covering 10 facing one another. A width 37 of the bridging element 22 is preferably dimensioned larger than a clear width 38 of the slot to be bridged 14. In particular, the lateral edge portions 33, 34 of the bridging element 22 overlap zones 39, 40, via which the bridging element 22 with the sliding board tongues 16, 17th non-positively, in particular adhesively connected. This adhesive connection is designed in such a way that the bridging element 22 merges with the outer surface edges of the lateral edge sections 33, 34 in the overlapping zones 39, 40 or with the outer edges of the lateral edge sections 33 as smoothly as possible into the tread covering 10. In particular, gaps in the transition section between the bridging element 22 and the tread surface 10 should be avoided as far as possible. The underside or the lower surface of the bridging element 22 lies predominantly in a cross-sectional view of the sliding device 1, ie more than 80%, above the underside 9 of the running surface covering 10. Preferably, the underside of the bridging element 22 is entirely above the underside 9 of the running surface covering 10 arranged. The bridging element 22 terminates flush in its lateral edge sections 33, 34 with the sliding surface or underside 9 of the tread covering 10 (FIG. Fig. 5 ). Preferably, the bridging element 22, which has different processing properties than the tread surface 10, in particular shows a different behavior compared to grinding operations, at least predominantly Fig. 5, 6 - Or arranged entirely at a distance 41 above the sliding surface or bottom 9 of the tread 10, as best of Fig. 7 or off Fig. 8 is apparent. This avoids in an effective and cost-effective manner that the bridging element 22 is impaired with its elastomeric properties during grinding or other machining operations of the sliding surface of the tread 10 or is also subjected to a grinding process. This will cause melting, Scoring or other effects on the bridging element 22, in particular with respect to its surface avoided. In particular, the bridging element 22 for the slot 14 is prevented from being subjected to a grinding surface treatment during the production of the sliding device 1 or in the course of subsequent servicing operations on the sliding device 1, in particular during surface grinding work.

The perpendicular to the tread surface 10 provided distance 41 between the bottom 9 and between the sliding surface of the tread 10 and the lower surface of the bridging element 22 can be accomplished by a blunt connection between the inner side edges of the tread 10 and the outer side edges of the bridging element 22 like this Fig. 7 is apparent. The transition section is preferably provided with a rounding, like this Fig. 7 is apparent. Alternatively, the formation of a chamfer is possible.

Moreover, it is also possible to carry out lateral overlapping zones 39, 40 of the bridging element 22 such that these overlapping zones 39, 40 are positioned on the side of the tread covering 10 facing the core 6. Within these overlapping zones 39, 40, the bridging element 22 is preferably connected to the tread surface 10 by a plastic weld. In particular, the overlapping zones 39, 40 of the bridging element 22 may be integrally received in the sliding board tongues 16, 17, respectively, as shown in FIG Fig. 8 was exemplified. The distance 41 is approximately 0.5 mm to 3 mm. Mutually facing edge sections or transition zones of the tread covering 10 in the direction of the bridging element 22 may also be provided here with a chamfer or a rounding in order to avoid sharp-edged transitions within the tread covering 10.

According to the embodiment according to Fig. 9 For example, the bridging element 22 and the tread covering 10 may be formed from a one-piece plastic layer or plastic layer which extends seamlessly and without interruption between the two outer edges or control edges 11, 12 of the sliding device 1. In this case, a loop-shaped deflection 26 is executed in the central portion of the tread 10, which is preferably formed by a thermal deformation of the tread 10, which consists of a thermoplastic material or parts of a thermoplastic material.

How best of the Fig. 1 to 3 It can be seen that it is advantageous if, referring to the longitudinally opposite ends of the sliding board body, a front or first slot 14 and a rear or second slot 14 are embodied. In particular, the front slot 14 extends from a front end portion of the binding mounting portion, or from the vicinity of the mounting portion for the binding device 3 toward the front end, in particular through the blade portion of the sliding board body. The rear slot 14 extends from a rear end portion of the binding mounting portion or from the vicinity of the mounting portion for the binding device 3 toward the rear end, in particular to the rearmost end point of the sliding board body. At least the mounting portion for the binding device 3 and optionally subsequent zones are not slotted. Optionally, the slot 14 in the binding mounting zone may merge into a groove formed in the top 7 of the gliding board body. In plan view of the sliding board body thus results in a substantially X-shaped structure, as best of Fig. 2 is apparent.

Preferably, both the front slot 14 and the rear slot 14 of the sliding board body at least one geometry influencing means 19 associated with, as shown in the representations according to the Fig. 1 and 3 is removable. This makes it possible to significantly change or significantly influence the so-called sidecut or the waisting radius and the driving behavior of the sliding board body.

The bridging element 22 is preferably designed, in particular so shaped and / or elastic, that it protrudes elastically in terms of its width 37 of at least 10 mm in an end portion closest to the end of the gliding board body. That is, elastic stretching and recovery of the bridging element 22 of 10 mm in its end facing away from the binding mounting portion does not cause damage, particularly tearing, brittleness or overstretching of the bridging element 22.

The geometry influencing means 19 associated with the slotted end portions of the gliding board body may be configured such that a width 18 of the slit 14 is individually presettable changeable to suit the gliding board body's cornering behavior to the individual desires of the user to a certain extent to be able to. Alternatively or in combination, the geometry-influencing means 19 can also be designed such that a variability of the width 18 of the slot 14, which is dependent on the load or deflection of the sliding board body, is effected, as has already been explained above. Preferably, the geometry influencing means 19 comprises at least one spreading means 20 for individually adjustable and / or load-dependent variation of the width 18 of the slot 14.

How best of the Fig. 1 and 3 2, the spreading means 20 comprises, referring to a plane extending substantially parallel to the tread 10, at least two support or guide surfaces 42, 43 extending obliquely to the longitudinal axis of the sliding board body. Referring to the longitudinal center axis of the gliding board body, these are support or guide surfaces 42 aligned wedge-shaped with each other, wherein the longitudinal center axis of the sliding board body represents a bisecting line. In particular, the angle included between two inclined support or guide surfaces 42, 43 is substantially halved from the imaginary longitudinal axis of the gliding board body, as best shown Fig. 3 is apparent. These support or guide surfaces 42, 43 are preferably embodied in a plate-like force transmission element 44 and, by virtue of their angular orientation relative to the longitudinal axis of the gliding board body, produce a wedge or spreading action relative to the slotted portion (s) of the gliding board body. Preferably, a plurality of pairs of support or guide surfaces 42, 43 which are distanced from one another in the longitudinal direction of the sliding board body or force transmission element 44 are formed.

This plate-like force transmission element 44 is supported on the upper side 7 of the sliding board body and is held in a relatively movable manner with the sliding board body in at least one of its end sections relative to its upper side 7. Preferably, the wedge-shaped mutually aligned support or guide surfaces 42, 43 of the force transmission element 44 by obliquely to the longitudinal center axis of the force transmission element 44 extending slots 45, 46 are formed, whose walls form the support or guide surfaces 42, 43. Via these elongated holes 45, 46 and by means of appropriate screw means, the force transmission element 44 is connected to the sliding board body, in particular supported on the upper side 7 relatively movable, wherein at least one of the ends of the force transmission element 44 remains relatively movable in the longitudinal direction of Gleitbrettkörpers. Preferably, in the middle portion of the power transmission element 44 is the latter with the top 7 of the sliding board body in all Directions fixedly connected. This can be implemented, for example, with circular holes and corresponding screwing, as in Fig. 1 has been illustrated schematically.

The support or guide surfaces 42, 43 in or on the plate-like force transmission element 44 cooperate with abutment surfaces 47, 48 on the upper side 7 of the sliding board body. Alternatively, the inclined support or guide surfaces 42, 43 of the force transmission element 44 also with the facing inner longitudinal side walls 49, 50 of the slot 14 cooperate, as in Fig. 5 was indicated by dashed lines by way of example. In particular, 44 extensions 51, 52 are formed on the underside of the force transmission element, as was indicated by dashed lines. These extensions 51, 52 extending parallel or at an angle to the longitudinal central axis of the sliding board body can cooperate with abutment surfaces 47, 48 running obliquely to the longitudinal central axis of the sliding board body in the slot 14 or in the edge sections of the slot 14 and thus form the spreading means 20. However, the abutment surfaces 47, 48 may also be formed by extensions 53, 54 fixedly connected to the upper side 7 of the sliding board body, in particular by screws 55, 56 or by their screw heads.

The preferred plate-shaped power transmission element 44 with the support or guide surfaces 42, 43 formed therein or with the obliquely elongated holes 45, 46 formed therein extends according to the embodiment Fig. 1 over more than 50% of the length of the gliding board body. In particular, the ends of the plate-like force transmission element 44 overlap with the slots 14 in the sliding board body. In particular, the two end portions of the power transmission member 44 cover at least portions of the two slots 14 in the front ends of the sliding board body when the power transmission member 44 rests against the top 7 of the sliding board body, as best shown Fig. 3 is apparent. In addition, the plate-like force transmission element 44 is designed such, in particular in its width 57 such that the plate-like force transmission element 44 bridges the at least one slot 14 transversely to the longitudinal direction, in particular transversely to the longitudinal direction of the sliding board body. That is, the plate-like force transmission element 44 at least in one of its end portions, ie in an end portion overlapping the slot 14, such a large width 57 - see Fig. 1 . 6 - Has that a structural bridging of the slot 14 is formed. In particular, it supports the slot 14 at least partially overlapping end portion of the plate-like force transmission element 44 on the one hand on the left and on the other hand on the right sliding board tongue 16, 17 of the sliding board body from, as best of the Fig. 1 . 3 . 5 and 6 is apparent. This advantageously prevents the sliding board tongues 16, 17 formed on either side of the slot 14 from mutually strongly deviating from one another in the vertical direction relative to the underside 9 of the running surface covering 10 or varying in their height position relative to one another. In particular, the plate-like force transmission element 44 supports the two sliding board tongues 16, 17 in the vertical direction to the underside 9 of the tread 10 and thus suppresses or limits a vertical increase or deviation of the stressed when cornering Gleitbrettzunge 16; This is achieved in particular by the fact that the plate-like force transmission element 44 offers an increasing bending stiffness in its end section facing the slot 14 or has a higher torsional stiffness than the sliding board tongues 16, 17 or the sliding board body itself in its slotted end section. Alternatively or in combination, this is achieved in that the structural overlay and mechanical coupling between the plate-like force transmission element 44 and the sliding board tongues 16, 17 in total provides increased flexural rigidity or torsional rigidity for the sliding board tongues 16, 17 or the composite gliding board body. The bridging of the slot 14 by means of the plate-like force transmission element 44 thus has in addition to the purpose of forming a spreading means 20 for fanning at least one of the ends of the sliding board body also a stabilizing function for the created by the slot 14, in the direction perpendicular to the tread surface 10 relatively compliant sliding board tongues 16th , 17.

However, the distal ends of the force transmission element 44 remain relative to the top 7 of the sliding board body in the longitudinal direction relatively movable, so at relative displacements between the force transmission element 44 and the sliding board body spreading or narrowing of the slot 14 occurs in Gleitbrettkörper and thus the geometry influencing means 19 is created.

The at least one slot 14 in at least one end portion of the sliding board body has a length of between 20 cm and 100 cm in plan view of the top side 7 of the sliding board body. A width 18 or a clear width 38 of the slot 14 within its longitudinal central portion is between 10 mm to 20 mm. Through this sizing is present all a sufficiently significant change in the geometry of the sliding device 1 can be achieved without the stability or practicality and robustness of the sliding device 1 falls into critical or insufficient areas.

How best Fig. 5 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 mutually facing longitudinal side walls 49, 50 of the slot 14, as best shown in FIGS Fig. 5, 6 is apparent.

The plate-like force transmission element 44 is supported within its longitudinal extension, 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 force transmission element 44 is supported almost over the entire surface on the top side 7 of the sliding board body. Alternatively, it is also possible to provide on the underside of the plate-like power transmission element 44 sparsely arranged support zones relative to the top 7 of the sliding board body. In this case, the support zones are positioned at least in the end sections of the force transmission element 44 such that the plate-like force transmission element 44 is supported on the sliding board tongues 16, 17 in a load-transmitting or force-transmitting manner.

To obtain advantageous effects, it is expedient if the plate-like force transmission element 44 extends over more than 50% of the length to the rear end of the gliding board body, starting from a binding mounting center point 58 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 favorable if the force transmission element 44 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 extension of the plate-like force transmission element 44 is essentially limited in that the plate-like force transmission element 44 is not intended to extend into the upwardly curved blade section or end section of the sliding board body, not with respect to the relative displacements between the ends of the plate-like force transmitting member 44 and the sliding board body to be obstructive when this leaf spring-like packet of force transmission element 44 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 transmission element 44, if the plate-like force transmission element 44 were to extend into the blade portion of the gliding board body in a rectilinear or equally upwardly curved shape. In particular, when the plate-like force transmitting member 44 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 58 and the respective end of the sliding board body or with respect 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 44 is provided for load-transferring support, in particular for mounting a binding device 3 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 44. As is known per se, the binding device 3 can comprise a front and a heel jaw, 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 44. For connecting the jaw body or the rail arrangement of the binding device 3 with the upper side of the force transmission element 44, at least one screw means 59, 60 is provided. In particular, a sufficiently tear-resistant connection between the force transmission element 44 and the binding device 3 can be established via this at least one screw means 59, 60. The binding device 3 is thus supported with the interposition of the plate-like power transmission element 44 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 62, 63 between the underside 61 of the plate-like force transmission element 44 and the upper side 7 of the gliding board body. This positive, preferably paired coupling means 62, 63 between the underside 61 of the plate-like force transmission element 44 and the top 7 of the sliding board body extends substantially within a mounting zone for the binding device 3, as best of all 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 44 and the sliding board body is made possible, as shown in Fig. 4 was exemplified.

The interlocking coupling means 62, 63 is designed such that longitudinal displacements permit compensating relative movements between the force transmission element 44 and the gliding board body in the longitudinal direction of the gliding board body when the gliding board body and the plate-like force transmission element 44 are subjected to a deflection, as for example when driving through depressions occurs. On the other hand, the positive coupling means 62, 63 are designed such that it prevents possible relative displacements between the force transmission element 44 and the sliding board body in the transverse direction to the longitudinal extent and substantially parallel to the tread surface 10 of the sliding board body as possible or increased resistance opposes such displacement tendencies. That is, the at least one positive coupling means 62, 63 permits relative displacements between the plate-like force transmitting member 44 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 member 44 and the top 7 of the sliding board body, 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 44 and the sliding board body thus favors the most direct or instantaneous transmission of forces between the force transmission element 44 and the sliding board body, without the sliding board body would be blocked in its bending behavior of the plate-like power transmission element 44.

The positive coupling means 62, 63 is preferably designed such that on the underside 61 of the force transmission element 44 at least one wart- or strip-like projection 64, 65 is formed, which in a corresponding or opposite recess 66, 67 in the top 7 of the sliding board body engages to improve the mechanical coupling between said components. The at least one, but preferably double-stranded, wart or projection-like projection 64, 65 on the underside 61 of the force transmission element 44 but also serves to receive the front portion, in particular the tip portion 68 of the screw means 59, 60 for attachment of the binding means 3 on the plate-like power transmission element 44. In particular, the front end or the tip section 68 of an anchored in the power transmission element 44 screw means 59, 60 for fixing the binding means 3 within this warzen- or strip-like projection 64, 65 on the underside 61 of the force transmission element 44. This is mainly a Relatively safe removal anchorage of the screw means 59, 60 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 44 achieved. The previously described screw means 59, 60, whose tip portions 68 extend into the material of the projections 64, 65, 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 Anankerungs- or Verschraubungslänge within the plate-like force transmission element 44 is present when the at least one projection 64, 65 on the underside 61 of the force transmission element 44 is advantageously used to increase the depth of engagement for the screw means 59, 60 how best this is Fig. 4 is apparent.

As if from a synopsis of Fig. 1 . 2 and 4 As can be seen, a profile height 69 of the at least one, preferably strip-like projection 64, 65 decreases continuously from the binding mounting center point 58 towards the rear and front end of the sliding board body and preferably runs to zero. Similarly, a receiving depth 70 of the at least one, preferably groove-like depression 66, 67 progressively decreases from the bonding mounting center point 58 towards the back and front end of the sliding board body and preferably also approaches zero. That is, the at least one recess 66, 67 and the at least one projection 64, 65 corresponding thereto terminate from the binding mounting center point 58 toward the distal ends of the gliding board body and the plate-like force transmitting member 44, respectively, terminating in front of the ends of the gliding board body , For example These protrusions 64, 65 gradually flatten with increasing distance from the bonding mounting center point 58, and eventually completely disappear from the underside 61 of the plate-like force transmission member 44. However, the projections 64, 65 and / or the corresponding recesses 66, 67 can also end in a jump. How best of the Fig. 1 and 2 it can be seen, runs the at least one recess 66, 67 in the top 7 of the sliding board body immediately before the sliding board tongues 16, 17 or in front of the slot (s) 14. Conveniently, therefore, the opposite end portions of the recesses 66, 67 pass over flush or flush in the top 7 of the sliding board body, as especially the perspective view in Fig. 1 can be seen. The sliding board body thus has the groove-like recesses 66, 67 in its central portion, in which the sliding board body has a sufficient or comparatively large thickness or thickness. With increasing distance to the binding mounting center point 58, in which the gliding board body usually has the greatest thickness, the recess 66, 67 can thus have the largest receiving depth 70, while the receiving depth 70 becomes progressively smaller with increasing approach to the end portions of the sliding board body or abruptly reduced and finally preferably expires towards zero.

It is essential that the screw means 59, 60 anchored for fixing the binding means 3 only within the plate-like force transmission element 44 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 44 and the sliding board body is maintained when the said components are turned 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 59, 60 for fixing the binding means 3 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 44 set tear-off. In particular, it is advantageous if the profile height 69 of the wart or strip-like projection 64, 65 and a plate height 82 of the plate-like force transmission element 44 is at least equal to or greater than a screwing depth 83 of the screw means 59, 60 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 firmly connected exclusively to the plate-like power transmission element 44, without a direct or direct screwing with the sliding board body.

In Fig. 10 is another embodiment of a structural combination of a board-like slider and supported thereon, a plate-like power transmission element 44 in a simplified, exemplary exploded and cross-sectional view illustrates. For parts already described above, the same reference numerals are used and the preceding descriptions are mutatis mutandis to the same parts with the same reference numerals transferable.

From this it is clear that, similar to the sliding board body, the plate-like force transmission element 44, which preferably forms part of the geometry influencing means 19 - Fig. 1 represents, as well as a multilayer composite body 71, in particular as a so-called sandwich-compound element is executed. That is, the plate-like force transmitting member 44 is formed of a plurality of adhesively bonded layers and similar to the actual sliding board body is made by a hot press in a hot pressing process, as is known for the creation of skis and snowboards or the like.

In particular, the plate-like force-transmitting element 44, in its function as a component of the geometry-influencing means 19, comprises Fig. 1 - At least one strength-relevant lower flange 72, at least one strength-relevant top flange 73, at least one interposed core element 74 and at least one on at least one side decorated or to be decorated cover layer 75 on the strength-relevant top flange 73. The underside 61 of the plate-like force transmission element 44 is preferably by a sliding layer 76 formed from plastic. This sliding layer 76 has a reduced or minimal frictional resistance with respect to the upper side 7 of the cover layer 8 of the sliding board body. In addition, the sliding layer 76 with respect to the cover layer 8 is made as abrasion resistant. The sliding layer 76 on the underside 61 of the plate-like force transmission element 44 may be formed by a thermoplastically moldable plastic layer which has similar properties as the surface or the cover layer 8 of the sliding board body or similar properties as the tread surface 10 of the sliding board body.

A thickness of the sliding layer 76 of the plate-like load or force transmission element 44 is between 0.1 to 2 mm, preferably about 0.4 mm. To achieve optical contrasts, the sliding layer 76 is preferably colored. Similar to the tread covering 10 of the sliding board body, the sliding layer 76 of the plate-like force transmission element 44 preferably also extends over the entire width 57 of the plate-like force transmission element 44, as shown in FIG Fig. 10 was exemplified. Also with regard to the longitudinal extension of the force transmission element 44, the sliding layer 76 preferably extends over the entire length of the force transmission element 44. In particular, the sliding layer 76 forms quasi the lower end of the force transmission element 44, so that at least a predominant part of the underside 61 of the force transmission element 44 formed by the sliding layer 76 is.

At least the predominant number of the individual layers or elements of the multilayer, plate-like force-transmitting element 44 is thereby formed and connected to the one-piece, multilayer composite body 71 by means of a heating press, in particular in at least one hot pressing process for the various layers or elements laid in a heatable mold ,

The at least one strength-relevant lower belt 72 and / or the at least one strength-relevant upper belt 73 comprises at least one layer of a so-called prepreg, ie a layer of a fabric impregnated with heat-flowable synthetic resin, for example a glass fiber fabric. In addition, the top flange 73 may include an additional bond anchoring layer 77. This binding anchoring layer 77 extends substantially within a partial section of the force transmission element 44, in which later the binding device 3 - Fig. 1 via screw 59, 60 Fig. 1 and 10 - Is set directly or indirectly via guide rails or so-called binding support plates on the power transmission element 44. The lower and / or upper belt 72, 73 of the plate-like force transmission element 44 may also have metallic layers and / or strength-increasing plastic layers in addition to the strength or stiffness relevant prepreg layers, as is known from the prior art in various embodiments.

The core member 74 of the plate-like power transmission member 44 may, for example be formed by an at least partially prefabricated element made of rigid foam and / or wood. Optionally, the core element 74 is surrounded by a tubular sheath 78, which is intended to improve the adhesive connection with the surrounding layers, at least in sections.

The sandwich structure of the multilayer composite body 71 results in a plate-like force transmitting member 44 which achieves a relatively torsional rigidity. The torsional or torsional stiffness of the plate-like force-transmitting element 44 is so high that upon the action of loads occurring during driving on only one of the two sliding board tongues 16, 17 Fig. 1 - A height offset between the two sliding board tongues 16, 17 in the vertical direction to the tread surface 10, especially by the plate-like power transmission element 44 is at least inhibited or reduced or prevented. That is, the plate-like power transmission element 44, a splintering of the two sliding board tongues 16, 17 in the vertical direction to the tread surface 10 increased resistance opposes or such height variations between the two sliding board tongues 16, 17 as possible as far as possible to achieve a certain extent. In particular, via the plate-like force transmission element 44, which at least in sections via the two sliding board tongues 16, 17 Fig. 1 - extends load-transmitting, prevents one of the two sliding board tongues 16; 17 is a much greater deflection or deformation is covered, as the other sliding board tongue 16 or 17. In particular, the degree of deformation of the loaded when cornering sliding board tongue 16; 17 held approximately equal to the degree of deformation of the unloaded sliding board 16 or 17. This is achieved primarily by the plate-like force transmission element 44, which is supported by two sliding board tongues 16, 17, such as, for example, from Fig. 1 or 3 is removable. This force transmission element 44 therefore also ensures that a relatively uniform deformation, in particular bending of the two sliding board tongues 16, 17, occurs at least within the overlapping area between the force transmission element 44 and the sliding board tongues 16, 17. The plate-like force transmission element 44 is to a significant extent co-determining the bending behavior or for the flexural stiffness distribution of a composite, ready-to-use gliding device 1, in particular a correspondingly designed alpine or carving ski. 2

A mean height or thickness 79 of the plate-like power transmission element 44 is between 0.5 to 3 cm. In particular, the thickness 79 of the multilayer plate-like force transmission element 44 is between 50% and 150% of the thickness of the gliding board body within the bond mounting zone. At the in Fig. 10 illustrated, advantageous embodiment corresponds to the overall height or thickness 79 of the plate-like force transmission element 44 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-like force transmission element 44 and the actual gliding board body is within the binding mounting area, as in Fig. 10 exemplified, maximum 5 cm, preferably 2 to 3 cm. This relatively low overall height of the sliding device 1 and its still practical strength or rigidity is achieved mainly by the multi-layer, plate-like load transfer body, in particular by the plate-like power transmission element 44, which is coupled across at least one positive coupling means 62, 63 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 44, a binding device 3. The screw means 59, 60 - Fig. 1 - For direct or indirect mounting of the binding device 3 are anchored exclusively in the plate-like power transmission element 44. The plate-like force transmission element 44 in turn is via separate screw means, for example in the region of the binding mounting zone, but preferably at or near the binding mounting center point 58 - see Fig. 1 - As rigid as possible and firmly connected to the actual sliding board body in all directions. In particular, the plate-like force transmission element 44 in the region of the binding mounting center point 58 is rigidly connected to the gliding board body via at least one screw, as shown in FIG Fig. 1 has been illustrated schematically. In the opposite, relative to the underlying sliding board body freelance-mounted end portions of the plate-like force transmission element 44, the at least one geometry influencing means 19 is executed, which can cause a spread or fanning of at least one end portion of the sliding board body.

As in Fig. 1 has been schematically illustrated, the plate-like force transmission element 44 via a plurality of longitudinally spaced apart screw means connected to the sliding board body such that a lifting or detachment of the plate-like force transmission element 44 is prevented from the top 7 of the sliding board body. In particular, 3 screw means may be provided, especially in the vicinity of the jaws of the binding device, which connect the plate-like force transmission element 44 via slots aligned parallel to the longitudinal direction of the force transmission element 44 with the underlying sliding board body such that different bending or chord lengths can be compensated as freely as possible between the components mentioned.

From the illustration according to 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 44 and the gliding board body to be arranged thereunder. The board-like sliding device 1 is thus executed at least two or more parts, said components being coupled together via form-locking connections and screw connections.

It may also be expedient to reinforce the plate-type force-transmitting element 44 in the subsection of the geometry-influencing means 19, for example by integrating or fitting at least one reinforcing layer, as shown in FIG Fig. 1 was schematically illustrated with dashed lines. Such a reinforcing layer is particularly useful in the immediate vicinity of the spreading means 20 and the slots 45, 56, wherein the reinforcing layer is preferably penetrated by the slots 45, 46.

In Fig. 11 the underside 61 of the plate-like force-transmitting element 44 is exemplarily and schematically illustrated in the region of the binding-mounting center point 58.

In this case, 44 two mutually parallel, strip-like projections 64, 65 are formed on the underside 61 of the plate-like force transmission element, which in at least approximately corresponding recesses 66, 67 - Fig. 10 - Can engage on the top 7 of a sliding board body, as previously described. With reference to the longitudinal direction of the plate-like force transmission element 44, the plate-type force transmission element 44 preferably has only one fixed point 80 or a fixation zone which is as short as possible relative to the sliding board body to be arranged thereunder. Is preferred this fixed point 80 or this fixation zone positioned near the binding mounting center point 58. At this fixed point 80 or within this narrow fixing zone, the plate-like force transmission element 44, preferably via screw, in all directions largely unyielding or rigidly connected to the sliding board body to be arranged under it. At this fixed point 80 so all relative displacements between the plate-like power transmission element 44 and the sliding board body are prevented. With increasing distance from this fixed point 80, however, increasing relative displacements between the plate-like force-transmitting element 44 and the sliding board body are made possible when the said components are subjected to a sag or bend.

At this fixed point 80 or as close as possible to this fixed point 80, at least one thickening 81 or at least one constriction can be made on the underside 61 of the plate-like force transmission element 44, which can be positively coupled to a corresponding depression or elevation on the upper side of the gliding board body. As a result, forces directed in the longitudinal direction of the force transmission element 44 can be better absorbed relative to the gliding board body. In particular, it is expedient to build a positive connection in the region of the fixed point 80 by means of corresponding depressions or elevations, which reliably prevents relative displacements between the force transmission element 44 and the gliding board body. Another advantage is that the plate-like force transmission element 44 can be easily placed on the top of the gliding board body during assembly and is also positioned as planned in the longitudinal direction, resulting in assembly simplifications in the connection or screwing of said components. An advantage of this form-locking connection is also that longitudinal forces or shear or pushing forces can be partially absorbed by this positive connection and not the entire load must be absorbed by the screw-like fasteners. As a result, the number of screw-type fastening means can be reduced in number and / or dimensioned smaller.
