Abstract

The layers with a core arranged between them form at least one sandwich component, in which there is at least one anchoring component for retention of a ski binding. The anchoring component (54,55) extends over a part area of a width of the ski (2), and over a part area of the length of the ski. It is formed by a layer, which extends in or parallel to the neutral layer plane (58) of the ski.

Description

The invention relates to a ski, in particular an alpine ski, with several between a tread covering and a top layer arranged with a form at least one Saudwich element between the layers arranged core and with at least one anchoring element arranged in it for holding purposes a ski binding.

WO 93/12845 A2 includes a ski with a plate-shaped mounting element shown for the coupling parts of a ski binding. The mounting element for the ski binding is formed by a relatively hard plate, which is interposed a damping layer is connected to the ski body. The connection is designed in such a way that the braced against the ski body via the damping layer Mounting element at least in their front and rear end areas relative to the ski body in the longitudinal direction is movable. For this, among other things suggested recesses in the side cheeks of the ski or even the two Provide penetrations penetrating side cheeks, which with the damping material are filled in and embed a cross bolt. By in the damping material embedded cross bolts to hold the mounting element should desired "floating storage" of the mounting plate relative to the sports equipment achieved become. The disadvantage here is that the proposed mounting of the mounting element for the ski binding, the transfer of the ski skier's transfer Steering forces on the long side edges of the ski body is delayed and consequently that Tax behavior of the ski seems sluggish. In addition, the edge grip is reduced, which affects especially the driving behavior on hard slopes. Furthermore is it is disadvantageous that the relatively large volume to be carried out for a comprehensive embedding Ausnebmungen or breakthroughs in the ski body a significant weakening of the Represent body. The bending characteristic of the ski is therefore in the range of the damping material and the cross bolts provided recesses considerable Have dips, so that such a ski relatively high vibration or so-called Has flutter tendencies and therefore driving behavior is also negative being affected. In addition, the provided with the damping material and thus in flexible recesses in the ski body, significant weaknesses in strength and lead to overloading of the ski, primarily resulting in breaking points of these recesses in the body.

EP 0 744 197 A1 describes a ski with an upper side integrated in the ski or top layer shown through breakthrough binding part carrier. The binding part carrier extends like a bridge between the two steel edges of the ski body and is supported directly on the steel edges. At least one of them A projection receiving plate supports the upper side of the ski body for the ski binding parts. The disadvantage is that the skier within one relatively short longitudinal extension directly on the steel edges a high load is exercised, which causes a deviation from the ski body or can even result in permanent deformation of the same and when penetrating Moisture increases the risk of ski delamination. Relatively in training however, extensive support arms for support on the steel edges become a disadvantage Stiffening of the ski.

EP 0 755 703 A1 describes a support element which is essentially U-shaped in cross section known for receiving the coupling parts of a ski binding. The legs of the Carrying element are interposed with an elastically deformable Layer connected to the side cheeks of the ski body, so when applied accordingly high forces relative movements between the V-shaped support element and the ski are possible. The disadvantage here is that the support element for the ski bindings is movable in the vertical direction to the top of the ski body and the Ski thereby indirect steering behavior or a relatively passive driving behavior having.

According to DE 295 11 954 U1, a mounting system for ski bindings is proposed, which carrier plates for the ski bindings similar to the functional principle a vice or a clamp on the long side walls of the ski body can be clamped. The disadvantage here is that the ski body at least over the Length of the clamping surfaces is limited in its natural flexibility and the Clamping force between the base plate and the ski body under high loads can hardly be maintained in the long term.

DE 41 12 299 A1 describes a ski with a carrying device for a ski binding known. The support device supporting the coupling parts of the ski binding is included in its central area via an axis running transversely to the longitudinal direction of the ski hinged to the ski, so that the carrying device can pivot together with the ski binding around this central axis. Between the ski and the support device are in the area in front of the axis and in the area behind the Axle resilient support elements arranged, the pivoting movement of the Opposing support device to a defined resistance relative to the ski. adversely is here that by the pivoting movements caused by loads the carrying device for the ski binding relative to the ski occasionally occurring roll tendencies or difficulties in maintaining balance for the user can already lead to a fall. Furthermore, the user on the sports equipment forces to be transmitted, in particular the forces acting in the vertical direction are delayed, which makes precise control of the ski difficult.

Furthermore, a vision with a binding support plate is known from DE 21 35 450 A. This binding support plate is spaced apart from one another in the longitudinal direction of the ski and attached to the ski fixed storage devices on the top. A the bearing devices form an articulated connection between the binding support plate and the ski and the further storage device forms a joint socket Guide device between the binding support plate and the ski. adversely is that the attached to the top of the ski storage devices for the binding support plate cannot withstand the forces occurring during driving or in the case of large-scale storage devices, the desired, uninfluenced Elasticity or deformability of the ski cannot be achieved.

The present invention has for its object a ski, especially for to practice alpine skiing, even after the ski binding has been installed shows hardly any changes in the characteristic parameters and the enables a simplified installation of the ski binding.

This object of the invention is achieved in that the anchoring elements in Area of a neutral layer of the ski, in which the oppositely directed Tensile and compressive forces when the bending stress is aligned perpendicular to the tread lift, rigid in the ski body are fixed. Which is through the object The surprising advantage of claim 1 is that the ski for assembly of the ski binding, its structure remains completely unchanged and therefore the parameters considered the cheapest by the producer, e.g. the bending parameter, the bending stiffness distribution and the breaking strength, even after the binding assembly remain secure. For mounting the ski binding on the Ski is any mechanical processing of the ski body, e.g. chipping Machining by drilling holes in the ski body, or chemical Edits such as Gluing, unnecessary. Through the mechanical processing So far there has always been a change in the characteristic values, e.g. of flexibility of the ski, which is clearly recognizable and recordable with suitable measuring means are. Due to the claimed training, these are adverse effects now largely eliminated. Supporting the ski binding in the neutral Zone or in the neutral layer of the ski, which is perpendicular to the tread directional bending stress is defined in the ski that is considered a composite, now enables a highly stable cross member to hold the ski binding in to integrate the construction of the ski without reducing the flexural rigidity or the To negatively influence the flexibility of the ski. By arranging the anchoring elements The tensile and compressive stresses are in the neutral layer of the ski the anchoring elements kept to a minimum. This is also the tension of the anchoring elements in the ski body or those on it in the event of deflection forces acting on the ski are absolutely minimized and the multi-layer ski structure is protected as best as possible from its dissolution. The length of the neutral fibers or the neutral layer remains constant even when the ski is subjected to bending stress, whereas when the ski binding is fixed on the top of the ski the upper fibers are compressed or shortened during a deflection and the lower fibers stretched or extended. If the ski bends, it happens for tensile stresses in the lower and compressive stresses in the upper cross-sectional area of the ski, whereas these opposing force components are advantageously canceled in the neutral layer. Directly in the neutral layer or on the corresponding zero line in the force diagram the stresses therefore have a value of 0, which means that they are absolutely free of forces consists. In narrow areas around the neutral layer or around the neutral level the tensile and compressive stresses are very low, which in an advantageous manner and the best possible binding assembly position in terms of tensionlessness and lack of strength is used.

An embodiment according to claim 2 and / or 3 is advantageous because it creates a pull-out anchoring of the ski binding is achieved without doing anything essential To influence the ski parameters,

An embodiment according to claim 4 is also advantageous, since it causes the surface pressure in the ski body can be greatly reduced and thus the stress on the individual components is particularly low.

The embodiment according to claim 19 is also advantageous, since it increases the uprising position the foot or shoe of the user is achieved when cornering enables strong inclinations with the sports equipment, without the shoe Touch the surface.

However, an embodiment according to claim 20 is also advantageous, since this means that when Driving through undulating terrain caused deformation movements of the Skis are allowed unhindered and therefore stiffening in certain areas, above all in the binding assembly area of the ski are avoided.

An embodiment according to claim 21 is also advantageous, since it enables the support element can be easily mounted on the ski and thanks to the high-strength training the construction of a highly stable and reliable connecting device is possible for the two support element parts.

The advantageous developments according to one or more of claims 22 up to 26, the mounting of the support element on the skis is simple and in a short time perform. In addition, all are for the connection of the support element with the ski relevant parts are effectively assigned to the two support element parts, which have a high strength, resulting in a correspondingly high connecting force can be applied.

The advantageous development according to one or more of claims 27 to 29 becomes the guiding device between the two large-area supporting clip parts formed, causing the surface pressure between the guide steep the guideway is very low and therefore wear and tear even with hard and long-term operation are excluded. The decoupling of the longitudinal guide device from the joint arrangement, i.e. the hinge assembly and the guide device are separated from each other in terms of area, also enables larger dimensions Joint and guide parts.

The advantageous embodiment according to claim 30 prevents bias and changes the safety-relevant trigger values between the shoe holders Coupling parts of the ski binding when the ski is deformed or bent.

However, an embodiment according to claim 31 is also advantageous, since this means that both jaw bodies the ski binding is fixed immovably on this one support element part can be and the necessary for the unimpeded bending of the ski Longitudinal compensation directly between the two support element parts in one end area the same can be done.

However, further training according to one or more of the claims is also advantageous 32 to 34, as this enables the ski binding or of the support element for the ski binding is made possible.

1 to 4 is an embodiment of a sports device 1 according to the invention, in particular a ski 2, with a support element 3 mounted thereon, which Coupling parts 4, 5 of a ski binding 6 for releasable connection to a shoe User camps, shown.

The sports device 1 or the ski 2 is formed from a sandwich element 7, which consists of several interconnected layers, with approximately the central position of the multilayer sandwich element 7 represents a core 8 which is in relation to the these surrounding layers have comparatively large cross-sectional dimensions. The core 8 preferably consists of wood, in particular of several glued together and thus to a one-piece component connected slats 9, 10, which are preferably formed from hardwood.

The cross-sectionally substantially U-shaped support element 3 is in several parts, preferably formed in two parts, a first, essentially L-shaped in cross section Support element part 11 via a connecting device 12 with another, in cross section also substantially L-shaped support member part 13 for the aforementioned one-piece support element 3 can be connected, so that overall the substantially U-shaped cross-sectional shape of the support element 3 is formed.

The U-shape of the support element 3, which is related to cross-sectional planes, is in this exemplary embodiment given at least in end regions 14, 15 thereof, whereas the support element 3 in an intermediate central region 16 in cross section in essentially corresponds to the cross section of a plate-like component. Accordingly protrude at least in the end regions 14, 15 of the support element 3 two legs 17, 18; 19, 20, which are spaced from one another approximately in accordance with the width of the ski 2, in the direction of below a support surface 21 on the support element 3 for the foot of the User arranged ski 2.

The assigned to the front end region 14 and approximately in one of the width of the Legs 17, 18 spaced apart from one another corresponding to ski 2 have in FIG an end region facing away from the support surface 21 for the user's foot Bearing devices 22, 23, via which the support element 3 with the sports device 1, is particularly connectable to the ski 2. Likewise, the end region 15 of the Assigned support element 3 and also approximately in the width of the ski 2 to each other distanced legs 19, 20 of the support element 3 in their lower, from the support surface 21 facing away end regions bearing devices 24, 25 for connection to the Sports equipment 1, especially with the ski 2.

The in plan view of the sports device 1 substantially rectangular and in their Longitudinal extension substantially parallel to a longitudinal direction - arrow 26 - des Ski 2 aligned and substantially parallel to a tread 27 of a Tread surface 28 aligned support surface 21 on the support element 3 thus has this embodiment in the corner areas one towards the underlying Sports device 1 directed legs 17 to 20, which the support surface 21 in set a distance 29 above a top 30 of the ski 2. On a bottom 31 of a substantially flat, central, forming the support surface 21 Plate part 32 of the connecting device 12 to the one-piece component Composite support element 3 is in each of the four corner areas Shaped legs 17 to 20, which are substantially rectangular from the bottom 31 of the plate part 32 protrude and in its end region facing the tread 27 are connected to the ski 2 via a respective bearing device 22 to 25. The Underside 31 of the central plate part 32 of the support element 3 is by a corresponding Arrangement of the bearing devices 22 to 25 in the legs 17 to 20 and / or through an appropriate choice of the connection points with the ski 2 on the vertical direction and / or by appropriate choice of the length of the legs 17 to 20 at a distance 33 above the top 30 of the ski 2, so that between the support element 3, in particular between that receiving the legs 17 to 20 central plate part 32 and the top 30 of the ski 2, a free space 34 is formed, which between the relative movements explained in more detail below the ski 2 and the support element 3 allows. The free space 34 between the bottom 31 of the support element 3 and the top 30 of the ski 2 is over the entire Length and width of the plate part 32 between this and the top 30 of the ski 2 given.

At least in the end regions 14, 15, the support element 3 is therefore in cross section in essentially U-shaped, the plate portion 32 supporting surface 21 for forms the foot of the user and in the corner areas the legs 17 to 20 accordingly preceding description are preferably formed in one piece.

The support element 3 is, as already described above, formed in several parts and has at least two support element parts 11, 13 with an L-shaped cross section on, which is assembled via the connecting device 12 to the one-piece support element 3 can be.

A separation and / or joining area 35 between the two essentially in cross section L-shaped support element parts 11, 13 run in the longitudinal direction - arrow 26 - des Ski 2 and essentially parallel to the running surface 27. In the separating and / or joining area 35 can support element parts 11, 13 via the connecting device 12 either assembled into a one-piece support element 3 or from one another be separated. Preferred are arrow 26 facing each other and in the longitudinal direction - Running leg plates 36, 37 of the support member parts 11, 13 additionally form-fitting connected with each other. The leg plates 36, 37 facing each other of each substantially L-shaped support element part 11, 13 thus form in the assembled Condition of the essentially flat, multi-part plate part 32 of the support element 3. For the positive connection of the two support element parts 11, 13 are in the mutually facing longitudinal edge regions of each leg plate 36, 37 corresponding recesses 38, 39 are provided, which are mutual enable positive connection.

In the simplest case, the leg plates 36, 37 of each support element part 11, 13 flattened to half the plate thickness, so that the flattened, assigned to each other Side areas of each support element part 11, 13 are assembled can and in total an essentially continuous, uniform thickness of the plate part 32 remains. The flattened, mutually facing longitudinal edge areas of the two support element parts 11, 13 thus result in a simple fold connection, which by means of suitable fastening means 40, in particular by means of screws 41 is secured against loosening.

The positive connection between the two in the longitudinal direction - arrow 26 - des Schis 2 aligned support element parts 11, 13 in the intermediate separating and / or Joining area 35 can also be formed by a tongue and groove connection be, as is shown schematically in Fig. 2. For this purpose, the indentations 38 the horizontally oriented leg plate 36 is formed such that in the other Support element 13 facing longitudinal edge region formed a spring 42 becomes. This spring 42 is dimensioned such that it is associated with one of them Groove 43 in the leg plate 37 of the other support element part 13 engage positively can. The groove 43 is thus formed by the indentation 39 in the support element part 13. The mutually corresponding tongue 42 and groove 43 of the support element parts 11, 13 is such via the fastening means 40, in particular via the screws 41 connected to each other that a relative movement between the two support element parts 11, 13 is prevented.

Of course, it is also possible to use the support element parts 11, 13 without the use independent fasteners 40 to connect. Here are the Supporting element parts 11, 13 are preferably inseparable from one another via snap connections coupled. Such snap connections are known from the prior art and can e.g. by one running in the longitudinal edge region of the support element part 11 Snap bar with a substantially circular cross-section and through a recess formed in the longitudinal edge region of the further support element part 13 formed with a substantially opposite, pan-shaped cross-sectional shape his. Both support element parts 11, 13 are for mounting the support element 3 or the ski binding 6 on the ski 2 to each other and by applying a corresponding biasing force to connect each other permanently. By applying or exceeding this pretensioning force then jumps Locking bar in the locking recess above, whereby the snap connection between the two support element parts 11, 13 is made. Such a snap connection is especially for materials with a sufficient modulus of elasticity, especially for Plastics or fiber-reinforced plastics or composites, in a simple way and possible way.

The support element parts 11, 13 are thus by the non-positive and / or positive connection via the connecting device 12, which fastening means 40 and / or includes positive connections to the one-piece support element 3, the total has a high dimensional stability, connected. That through the two support element parts 11, 13 two-part, but one piece via the connecting device 12 Component composite support element 3 has in particular a high torsional and Flexural rigidity, which usually all act on the support element 3 Torsional and bending forces, such as those that occur when driving with the sports device 1 can withstand. Due to the high torsional and bending stiffness of the support element 3 remain the coupling parts 4, 5 of the ski binding 6 among all occurring during driving Operating states in their relative position or relative position to each other completely unchanged, so that the preload of the coupling parts 4, 5 of the ski binding 6 on the shoe due to the absolutely bending and torsion-resistant or deformation-stable Support element 3 remains unchanged.

The support element 3 is in the end region 14 via a hinge connection 44 with the Ski 2 coupled. This hinge connection 44 between the support member 3 and the Ski 2 in the front end area related to the direction of travel of the sports device 1 14 includes the bearing devices 22, 23, in particular borehole-like recesses 45, 46 with a circular cross section in the legs 17, 18 and with these Recesses 45, 46 corresponding bearing journals 47, 48. These bearing journals 47, 48 are connected to the sports device 1 and to the ski 2 in a fixed manner and have a substantially circular cross-section, the diameter of which in essentially corresponds to the diameter of the associated recesses 45, 46, so that an as free as possible joint 44 between the support element 3 and the ski 2 is ensured.

In the distance from the front end region 14 in the longitudinal direction - arrow 26 - of the ski 2 the rear end region 15 is the support element 3 via a joint and guide device 49 with the sports equipment 1 or with the ski 2 articulated as well in the longitudinal direction - arrow 26 - of the ski 2 is relatively movable, in particular translationally can be moved and moved relative to one another. This joint and guide device 49 between the support element 3 and the ski 2 in the rear related to the direction of travel or further end region 15 also includes recesses 50, 51, which in particular than in the longitudinal direction - arrow 26 - of the ski 2 elongated holes in the legs 19, 20 are formed, the width of which essentially has a diameter of corresponds to the ski 2 fixed journal 52, 53 with a circular cross-section. Form the slot-shaped recesses 50, 51 in the legs 19, 20 in cooperation with the bearing pins 52, 53 firmly connected to the ski 2 Joint and guide device 49, which is both a rotational movement between the ski 2 and the support element 3 as well as a translational movement of the ski 2 relative to the support element 3 or relative to the legs 19, 20.

The bearing pins 47, 48 are at the ends of an anchoring element integrated in the ski body 54, which is essentially parallel to the running surface 27 or aligned with the tread surface 28 and substantially transversely to the longitudinal direction - Arrow 26 - of the ski 2 runs approximately over its entire width. The others rear bearing journals 52, 53 related to the direction of travel are also on the ends of an anchoring element 55 of the same type integrated in the ski body formed, which is also substantially parallel to the tread 27 and Tread surface 28 is aligned and also substantially transverse to the longitudinal direction - Arrow 26 - the ski 2 runs. The integrated in the ski body and in the longitudinal direction - Arrow 26 - of the ski 2 anchoring elements 54, 55 spaced apart from one another form over the journal 47, 48; 52, 53 pivot axes 56, 57, which essentially parallel to the running surface 27 and transverse to the longitudinal direction - arrow 26 - of the ski 2 are aligned and in the two in the longitudinal direction - arrow 26 - of the ski 2 to each other distanced connection areas of the ski 2 with the support element 3 each allow a rotational relative movement when the ski 2 is bent or bent becomes like this when driving through undulating terrain or when cornering given inevitably due to the waistline and / or the preload height of the ski 2 is. The support element 3 with the coupling parts 4, 5 of the ski binding fastened thereon 6 does not influence the flexural rigidity or the flexibility of the ski 2, since the hinge connection 44 and the hinge and guide device 49 between the supporting element 3 and the ski 2 allow the ski body to work freely. The The natural flex of the ski 2 is thus retained and that which is mounted on the support element 3 Ski binding 6 has no negative influence on that provided by the manufacturer of ski 2 Bending characteristic value or the bending stiffness distribution deemed to be the most favorable by the manufacturer of the sports equipment 1.

The two pivot axes 56, 57 formed by the anchoring elements 54, 55 run when projected onto a horizontal plane as well as when projected onto a vertical, transverse to the longitudinal direction - arrow 26 - the ski 2 vertical plane absolutely parallel to each other. The anchoring elements 54, 55 integrated in the ski 2 for connecting the ski 2 to the support element 3 are essentially in one plane aligned parallel to the running surface 27 or to the running surface 28 58 arranged and under certain conditions connect several in the longitudinal direction - Arrow 26 - center of gravity 59, 60 spaced apart from one another in relation to several Cross-sectional sections of the ski 2 spaced apart from one another. The anchoring elements 54, 55 and the pivot axes 56, 57 are in any case in the neutral fiber or arranged in the neutral layer of the sports device 1 or the ski body, i.e. the pivot axes 56, 57 and the anchoring elements 54, 55 are in those Areas arranged in the ski body, in which the occurring tensile and Eliminate compressive stresses in the event of a load or in the event of bending or bending and become zero. The largely untouched by tensile and compressive forces neutral fiber or neutral zone of the ski 2 depends in particular on the elasticity modules the individual layers of the ski 2 as well as their thickness and shape or geometry, but normally runs in the area of the core 8 and thereby parallel to the running surface 27 and in the longitudinal direction - arrow 26 - of the ski 2. The neutral The fiber or the neutral zone of the ski 2 is represented by the plane 58 and runs mostly parallel to the running surface 27 in about half the thickness of the ski 2. This level 58 connects especially in the case of a homogeneous, uniform ski body all longitudinal centers of gravity - arrow 26 - of the ski 2 59, 60 in the individual cross-sectional sections of the ski 2. The pivot axes 56, 57 lie in level 58 or in the neutral zone of the multilayer in particular Ski body and are aligned transversely to the longitudinal direction - arrow 26 - of the ski 2. in the shown embodiment runs the neutral zone or the plane 58 of the ski body through the core 8, in particular through the hardwood core of the ski 2. Die Anchoring elements 54, 55 thus penetrate the core 8 in the transverse direction of the ski 2 and are firmly connected to it or held there under pretension, so that displacements between the anchoring elements 54, 55 and the Ski 2 are prevented. The anchoring element 54, 55 preferably extends continuous across the entire width of the ski 2 and forms on each of the two Ends of the journals 47, 48; 52, 53 out. The preferred metallic anchoring elements 54, 55 penetrate the core 8, in particular the hardwood core, over Through bores 61, 62. Due to the essentially rigid and absolute The core elements 8, 55 which are integrated in the ski body in such a way that they cannot be pulled out are the anchoring elements 54, 55 or the pivot axes 56, 57 formed by this absolutely tear-proof and high strength held in the ski 2 or fixed extremely rigid and unyielding. The tear resistance or the absolutely fixed fixation of the anchoring elements 54, 55 in the Shaped body can be increased by projections 63, 64 projecting like wings. The anchoring elements 54, 55 can be bolt-like elements 65, 66 circular cross section can be formed, on the lateral surfaces of the elements 65, 66 the plate-like projections 63, 64 protrude radially. The plate-like projections 63, 64 can change with increasing distance from the central, botzen-like Element 65, 66 continuously taper in strength, so that in the central element 65, 66 distant areas are formed like longitudinal edges. The Projections 63, 64 thus have an approximately triangular or cutting blade-like Cross-sectional shape.

Several projections 63, 64 can also extend over the circumference of the bolt-like Elements 65, 66 can be arranged distributed. However, each element 65, 66 is preferred two projections 63, 64 are provided, the flat sides of which are substantially parallel to Running surface 27 or parallel to plane 58, so that the relatively high, perpendicular to the plane 58 or essentially perpendicular to the tread 27 Forces can be safely absorbed and a deviation of the central, bolt-shaped Elements 65, 66 in the ski body excluded from the intended position is. The projections 63, 64 on the anchoring elements 54, 55 result a higher contact surface of the same in the ski body, so that a deviation, e.g. on Sinking of the same in the ski body or a rotational movement of the same around the Pivot axes 56, 57 is avoided. The diameter of the ends of the Anchoring elements 54, 55 arranged journal 47, 48; 52, 53 is approximately 4 mm to 14 mm and preferably consists of a high-strength metallic material, e.g. made of steel or metal alloys, e.g. Titanal. The wing-like projections 63, 64 of the anchoring elements 54, 55 in the ski body each run in level 58 or in the neutral fiber of sports equipment 1 or ski 2. Likewise the pivot axes 56, 57 of the anchoring elements 54, 55 lie exactly in the plane 58 or in the neutral fibers of the ski construction and are transverse to the longitudinal direction - Arrow 26 - the ski 2 aligned.

The sandwich element 7, which is composed of several layers and which the sports device 1 or forms the ski 2, in addition to the essentially centrally arranged core layer or in addition to the core 8, in particular made of wood, these at least partially surrounding locations. In particular, the sandwich element 7 has one in the Upper edge areas of the ski body arranged top flange 67 and one of the tread 27 or the lower flange 68 assigned to the tread surface 28. At least there is an upper flange 67 and at least one lower flange 68 near the edge zones of the Schiquerschnittes provided, these layers of the ski 2 made of materials high strength and rigidity. Are preferred between the core 8 and the upper and lower straps 67, 68 elastic inserts made of plastic or foam arranged. If necessary, a filler 69, in particular made of plastic, can also be used or foam, arranged between the core 8 and the supporting straps be compared to the core 8, a higher elasticity or in the case of pressure loads has a lower resistance and thus also a damping function can take over in the body. This composite of the core 8, the top and Bottom belts 67, 68 and from the filler 69 is on the one hand from the tread lining 28 and on the other hand surrounded by a shell 70, which has a high mechanical strength having. If necessary, the supporting straps and the core 8 and the filler 69 surrounded by two shells, the outer shell 70 hard and the inner shell is comparatively soft. The longitudinal edge areas of the Shell 70 - as is known per se - directly adjoining the tread surface 28 Running edges 71, 72, which are preferably made of steel, from which a optimal power transmission is achieved.

The sports device 1 is therefore comparable to a rod made of composite material. The position and alignment of the neutral fibers - represented by level 58 - is included through the different elasticity modules of the individual layers and through the Cross-sectional geometry of the ski 2 determined. In the embodiment shown the individual elasticity modules and geometries of the individual layers of the ski body designed in such a way that the center of gravity 59, 60 in the plane 58 and in the neutral fiber of the ski body. Of course, it is also possible that the area center of gravity 59, 60 depending on the individual elasticity modules and geometries of the individual layers or layers of the composite material in addition the level 58 or next to the neutral fibers of the ski body. By generally to a vertical axis 73, in particular cross-section halves symmetrical to the z-axis The center of gravity of the ski body 59, 60 are always on this Vertical axis 73. The previous descriptions refer to the effects of force perpendicular to the running surface 27 or to the top 30 of the ski 2 when the ski 2 is held in the blade and end area. '

In Fig. 4, the course of tension of the ski 2 when bent about a horizontal, transverse to the longitudinal direction - arrow 26 - directed axis shown. The voltage curve is there very simplified and schematically presented and represents one of many possible Voltage curves as an example. From this diagram with the voltage curve in the individual layers of ski 2, the jumps on the individual are clear Material limits of the composite material can be seen. If the Ski 2, i.e. when ski 2 is loaded perpendicular to surface 30, lower flange 68 acts as the tension belt and the top belt 67 as the compression belt, with some tension and Compression forces in part by arrows 74, 75 for the tensile forces and by arrows 76, 77 are symbolized for the pressure forces. Lift in the neutral fiber - level 58 the opposing tensile and compressive forces on each other and one Voltage zero line 78, which defines the neutral fibers or the plane 58, is formed. Exactly at this voltage zero line 78 or in the neutral fiber - level 58 - is the anchoring element 54, 55 for mounting the dimensionally stable support element 3 arranged. The direction of the arrows 74 to 77 provides information in particular about the Train and pressure conditions in the ski body and their length provide information about the Amount or the amount of the forces.

As can be seen above all from FIGS. 2 and 3, the legs 17 to 20 of the Carrying element 3 used in recesses 79 to 82 in sports equipment 1 or in ski 2. These recesses 79 to 82 are arranged in the region of side cheeks 83, 84, the free space formed by the recesses 79 to 82 essentially the volume of the legs 17 to be inserted or introduced therein 20 of the support element 3 corresponds. Outer surfaces 85 to 88 facing away from one another on the legs 17 to 20 close largely flat with those through the side cheeks 83, 84 formed side surfaces 89, 90, so that a largely stepless Transition between the legs 17 to 20 of the support member 3 and the side surfaces 89, 90 is formed on the side cheeks 83, 84. This is the width of the sports equipment 1 also not enlarged by attaching the support element 3 and individual Projections on the side cheeks 83, 84, which interlock the ski pair Caused by skiing are excluded as the side surfaces 89, 90 of the side cheeks 83, 84 consistently flat or without substantial projections are trained. The inclination of the outer surfaces 85 to 88 of the legs 17 to 20 of the support member 3 is the inclination of the side surfaces 89, 90 on the side cheeks 83, 84 of the ski 2 adapted, which generally two outer surfaces 85, 86; 87, 88 diverging from each other and a theoretical intersection the same is formed in the vertical direction above the tread 27. inner surfaces 91 to 94 of the legs 17 to 20 are absolutely perpendicular to the pivot axes 56, 57 and are as free from play as possible on inner boundary surfaces 95 to 98 of the Recesses 79 to 82. Relative to the cross-sectional area of the support element 3 run the outer surfaces 85 to 88 and the inner surfaces 91 to 94 of the legs 17 to 20 so at an angle to each other, the inner surfaces 91 to 94 perpendicular to the Pivot axes 56, 57 and a theoretical intersection above the top 30 of the ski 2 is formed.

The recesses 79 to 82 or the corresponding indentations in the ski body have a vertical projection in the longitudinal direction - arrow 26 - pointing Lateral boundary surfaces 99 to 102 running at an angle to one another, a theoretical crossing line of the lateral boundary surfaces 99, 100; 101, 102 related to a vertical direction below the pivot axes 56, 57 and lies below the anchoring elements 54, 55. The recesses 79 to 82 are So starting from the tread 27 in the direction of the top 30 continuously expanding trained so that based on the longitudinal direction - arrow 26 - spaces between the Legs 17 to 20 and the inner boundary surfaces 99 to 102 of the recesses 79 to 82 are formed, the relative movements between the ski 2 and Allow legs 17 to 20 of the support element 20. To freeze the free spaces between the legs 17 to 20 and the inner boundary surfaces 99 to 102 of the To avoid recesses 79 to 82, these can be made with an elastic filler 103, e.g. a foam-like filler, which is a certain Resilience behavior and is comparatively easy to deform. You can also the remaining free spaces between the journals 52, 53 and the recesses 50, 51 in the legs 19, 20 filled with an elastic filler 104 to prevent the storage of ice and snow.

The injection of the filler 103, 104 into the remaining free spaces of the recesses 79 to 82 preferably takes place after the mounting process of the support element 3 on the ski 2.

The anchoring elements 54, 55 can either be used directly in the manufacture of the Sandwich element 7 integrated or inserted between the individual layers or can also be fixed in the ski body after the production of the ski 2. For this are in the through holes 61, 62 in the ski 2, the bolt-like anchoring elements 54, 55 to be pressed or hammered in. Especially when retrofitted of the anchoring elements 54, 55 in the ski body have the radially protruding ones Projections 63, 64 with which the pull-out strength of the anchoring elements 54, 55 is increased because these projections 63, 64 through the material cut through holes 61, 62 and anchor accordingly.

After the anchoring elements 54, 55 are fixed in the ski body, this can be done Support element 3 can be attached to the ski 2 in a simple manner. For this are only the two halves of the support element 3 or the support element parts 11, 13 on the bearing pins 47, 48; arranged in the recesses 79 to 82; 52, 53 attach and the two support member parts 11, 13 via the connecting device 12 to connect to the one-piece support element 3. After activating the connection device 12 is then a sliding of the support member parts 11, 13 and the Legs 17 to 20 of the journals 47, 48; 52, 53 excluded.

The inner surfaces 91 to 94 of the legs 17 to 20 are preferably on the comparative hard, lateral boundary surfaces of the core 8 and / or the top flange 67 and / or the lower flange 68 with as little play as possible.

5, 6 is a further training variant of the sports device according to the invention 1 or the ski 2 according to the invention, but for previously already described parts the same reference numerals are used. The embodiment 5, 6 may optionally be an independent, inventive Represent training of the sports equipment 1 and the ski 2.

Here, the support element 3 is formed in one piece and in turn on the in the Corner regions of the plate part 32 integrally formed legs 17 to 20 in the recesses 79 to 82 stored in the ski body. The support element 3 is preferably extruded or continuously cast profile with a U-shaped cross section, to which to Forming the four legs 17 to 20 of the central region 16 of the support element 3 reworked is. In particular, those protruding from the central plate part 32 Legs removed in the central region 16 of the profile, so that in the end regions 14, 15 the relatively narrow legs 17 to 20 are formed. The one-piece, one-piece support element 3 is in turn via the hinge connection 44 and via the hinge and Guide device 49 coupled to the ski 2. The firmly connected to the sports equipment 1 or in this integrated anchoring elements 54, 55 of the joint connection 44 and the joint and guide device 49 are here by hollow cylindrical Bearing bushes 105, 106 are formed. A longitudinal central axis of the bearing bushes 105, 106 runs essentially parallel to the running surface 27 and transversely to the longitudinal direction - Arrow 26 - the ski 2. These bearing bushes 105, 106 extend between the boundary surfaces 95, 96 shown in FIGS. 2 and 3; 97, 98 of the recesses 79, 80; 81, 82. The end faces of the hollow cylindrical Bearing bushes 105, 106 preferably close evenly with the in particular 2 and 3 visible boundary surfaces 95, 96; 97, 98, so that the in recesses 79 to 82 incorporated into the ski body with the support element removed 3 not of the various bearing parts between the support element 3 and the Ski 2 are penetrated or do not protrude into them. The distance between each other adjacent legs 17, 18; 19, 20 is again chosen such that it is flat and as free of play as possible at the boundary surfaces 95, 96; 97, 98 of the recesses 79 to 82. The bearing bushes representing the anchoring elements 54, 55 105, 106 are fixed rigidly and immovably in the ski body. The most deviant Positioning of the bearing bushes 105, 106 can in turn by the Radially projecting projections 63, 64 can be increased.

For mounting the support element 3 or the ski binding 6 on the sports device 1 only the support element 3 with the legs 17 to 20 in the recesses 79 to Use 82 and complete the connection by means of two bearing bolts 107, 108. The cross-sectional shape of the bearing bolts 107, 108 is chosen such that these can be inserted into the bearing bushes 105, 106 with as little play as possible. A length the bearing pin 107, 108 is selected such that it is greater than the length of the Bearing bushes 105, 106, in particular the length of the bearing bolts 107, 108 µm in chosen about a double thickness 109 of the legs 17 to 20 larger, so that the legs 17 to 20 are at least partially penetrated by the bearing bolts 107, 108. The Bearing pins 107, 108 in turn form the bearing pins 47, 48; 52, 53, whose diameter is essentially a diameter of the recesses 45, 46; 50, 51 in the legs 17 to 20 corresponds.

The bearing bolts 107, 108 are known from any of the prior art Means against arbitrary falling out of the bearing bushes 105, 106 after assembly of the support element 3 secured. So it is e.g. possible, the bearing bolts 107, 108 to glue in the bearing bushes 105, 106 or the bearing bolts 107, 108 by a corresponding press fit into the bearing bushes 105, 106 and thus to prevent them from falling out.

The central longitudinal central axis of the bearing bolts 107, 108 forms the pivot axes 56, 57 between the support element 3 and the ski 2. The pivot axes 56, 57 lie again on the neutral fibers - level 58 - of the ski 2, so that a largely tension-free embedding of the anchoring elements 54, 55 is given. The neutral fiber - level 58 - again runs in relation to the cross section of the ski 2 approximately in the center area and parallel to the tread 27.

For absolutely tear-proof fastening of the anchoring elements 54, 55 and the Bearing bushes 105, 106 can be provided with projections 63, 64 in the outer jacket area be provided in the manner of threads, so that the bearing bushes 105, 106 in the Ski body or are screwed into the through hole 61, 62 in the ski body can and thus are positively connected to the ski 2. A screw connection the anchoring elements 54, 55 or the bearing bushes 105, 106 is preferred applied to skis 2 with wooden cores. The bearing bushes 105, 106 with the am Outer sheath arranged threads in particular allow a subsequent Attachment of the anchoring elements 54, 55 in the ski body after the Through holes 61, 62 substantially parallel to the tread 27 and transverse to Longitudinal direction - arrow 26 - of the ski 2 were incorporated.

By a detachable connection of the bearing bolts 107, 108 to the bearing bushes 105, 106, it is possible in a simple manner to use a wide variety of support elements 3 different ski bindings 6 quickly and without tools on a specific ski 2 to arrange or to carry out a corresponding exchange without any problems.

7 shows another embodiment variant of the sports device 1 according to the invention or ski 2 with those designed to connect the ski 2 to the support element 3 Anchoring elements 54, 55 within the ski body. In the embodiment shown become the same reference numerals for parts already described above used, the same explanations for the same parts are valid.

The cross-sectional view through the sports device 1 or the ski 2 with the one on it fixed, one-piece support element 3 for holding the ski binding is a Sectional view through the bearings on the ski 2 in the end regions 14, 15 of the Support element 3, i.e. the anchoring elements 54 and 55 are each largely identical in the end region 14 and in the end region 15 of the support element 3 in the ski body integrated. In the following description, only the front anchoring element is used 54 referenced

Here, the anchoring element 54 consists of a piston-cylinder arrangement, wherein at least one cylinder 110 is formed with two pistons 111, 112 guided therein is. The cylinder 110 is in particular a hollow cylinder 113 or a sliding bush 114 designed for the pistons 111, 112. The cylindrical pistons 111, 112 are included aligned in the sliding bush 114 such that its longitudinal central axes 115, 116 form the pivot axis 56 and thereby in the neutral fibers - plane 58 - of the ski body lie. The two pistons 111, 112 are in relation to their longitudinal central axes 115, 116 axially adjustable relative to one another in the sliding bush 114, i.e. pistons 111, 112 are guided by the sliding bush 114 such that they in the direction of their longitudinal central axes 115, 116 are movable relative to each other and apart, in the other However, spatial directions are held as immovably as possible.

At least the end regions of the two pistons 111, 112 facing away from one another have a circular cross section and form the journals 47, 48 for the Supporting element 3. The pistons 111, 112 preferably have a cross section a circular outline throughout. Of course it is too possible, the mutually facing end areas, ie the areas following the Journal 47, 48, in cross section e.g. to be rectangular in shape and accordingly to provide rectangular guide bores 117, 118 in the sliding bush 114.

The mutually facing end regions of the bolt-like ones guided in the sliding bush 114 Pistons 111, 112 preferably have heads 119, 120 that fall out exclude the pistons 111, 112 from the sliding bush 114. A cross-sectional dimension of the heads 119, 120 at the mutually facing ends of the pistons 111, 112 chosen larger than a diameter of the journal 47, 48 in the spaced therefrom End regions. The heads 119, 120 have a corresponding guide recess 121 in the central area of the slide bush 114, with the transition from the guide recess 121 into the two guide bores 117, 118, respectively an approach 122, 123 is formed, the movement of the pistons 111, 112 from the Sliding bush 114 limited in cooperation with the heads 119, 120 formed thereon.

The pistons 111, 112 are under the action of a resilient pretensioning device 124, in particular a compression spring 125, in the initial or idle state of the Anchoring element 54 pushed into their greatest possible distance from each other. The elastic biasing device 124 thus causes a displacement of the two pistons 111, 112 in the most distant position, then the journals 47, 48 protrude from the front end areas 126, 127 of the sliding bush 114 Bearing journals 47, 48 project beyond the end regions 126, 127.

In particular, the anchoring element 54 forms a releasable one if necessary Connection device 128 between the ski binding or the support element 3 for the ski binding and the ski 2, which can be activated and / or deactivated without tools is. This connection device 128, which can only be operated manually, is included formed in the manner of a preferably lockable snap closure, which is an immediate and largely automatic connection of the ski binding to the ski 2 as well as a corresponding disassembly of the same.

The sliding bush 114 is preferably formed in two parts, the parting plane being preferred formed in the central region or in the region of the central guide recess 121 is to the two pistons 111, 112 with the heads 119, 120 in the slide bush parts to be able to use and around the biasing device 124 between the two To be able to attach heads 119, 120. The two parts of the sliding bush 114 are then via a connecting device, e.g. via a thread arrangement 129, assembled to the one-piece sliding bush 114. Of course it is possible, the connecting device by any other positive connections or also by non-positive connections, e.g. by gluing, by Welding or by an appropriate press fit and / or shrink fit, between the two parts of the sliding bush.

That the pistons 111, 112, the sliding bush 114 and the spring-elastic pretensioning device 124 comprehensive anchoring element 54 is integrated in the ski body so that it cannot pull out, the end regions 126, 127 of which have at least a partial region of the boundary surfaces 95, 96 of the recesses 79, 80 or indentations in the ski body form for inserting the legs 17, 18 of the support element 3. The anchoring element 54 is embedded between the individual layers of the ski 2, in particular, this is arranged between the upper flange 67 and the lower flange 68 and is partially enclosed by the filler 69 of the ski 2. The absolutely deviant Storage of the anchoring element 54 in the ski body can still optionally by the trained according to the previous descriptions or figures Projections 63, 64 are increased. Such an embedding of the anchoring element 54 in the ski body is preferably carried out immediately during the manufacture of the Sports equipment 1 or ski 2.

In addition, it is also possible to use the outer jacket of the anchoring element 54 to provide a threaded assembly 130. This thread arrangement 130 has a relatively large pitch and relatively high thread flanks, to insert the anchoring element 54 into a ski 2 that has already been manufactured to be able to. Here, between mutually opposite recesses 79, 80 a through hole 61 connecting this is provided, into which the anchoring element 54 can be screwed in with the thread arrangement 130 in a simple manner and is anchored in the ski body so that it cannot pull out.

To connect the support element 3 to the ski 2 via the anchoring element 54 are in the legs 17, 18, the recesses 45, 46 with a bearing journal 47, 48 arranged corresponding cross section. These recesses 45, 46 can formed as a blind hole or as a through hole in the legs 17, 18 his.

For mounting the support element 3 on the ski 2, only the pistons 111, 112 against the action of the elastic biasing device 124 in the sliding bush 114 to insert, so that the bearing pins 47, 48 at least with the same surface close the end regions 126, 127 of the sliding bush 114. Then that's it Support element 3 with the legs 17, 18 in the recesses 79, 80 insertable, and with overlap or aligned alignment of the guide bores 117, 118 with The recesses 45, 46 are the pistons 111, 112 by the elastic biasing device 124, in particular by the compression spring 125, moved apart, so that the bearing bolts 47, 48 engage in the recesses 45, 46 and the articulated connection 44 and also the joint and guide device 49 in the rear end region of the support element 3.

The support element 3 is simple by such an anchoring element 54 and way can be coupled to the ski 2 and is connected to it with high strength.

For automatic or tool-free coupling of the support element 3 to the ski 2 can be provided on the legs 17, 18 link tracks 131, 132, the one enable unimpeded, automatic snapping of the support element 3 onto the ski 2. These slide tracks 131, 132 are due to bevelled planes the legs 17, 18 formed when the support element 3 is placed on the ski 2 and when a pressing force acting in the vertical direction is applied to the ski 2 the pistons 111, 112 drive automatically into the sliding bush 114 and then this Jump overlap with the recesses 45, 46 again from the sliding bush 114 and engage in the recesses 45, 46. Such an anchoring element 54 or such a design of the support element 3 thus enables one absolutely tool-free mounting of the support element 3 with the ski binding on the ski 2. Accordingly, any support elements 3 with any ski bindings on one certain skis 2 are simply clicked on or clipped on.

The recesses can be used for any disassembly of the support element 3 from the ski 2 46 can be provided as through bores through which the pistons 111, 112 or the journals 47, 48 except by pushing them back into the sliding bush 114 Engagement of the legs 17, 18 of the support member 3 can be brought. The Decoupling of the support member 3 can therefore be done at any time by the Pistons 111, 112 or the bearing pins 47, 48 with suitable means in the sliding bush 114 be pushed. The recesses 45, 46 are then preferred for storage the support element 3 on the ski 2 can be optionally closed with a plug 133, to prevent ice or snow from entering.

In addition, it is also possible to use the pistons 111, 112 without the heads 119, 120 form when the recesses 45, 46 in the legs 17, 18 as blind holes are formed, by means of which the extension movement of the pistons 111, 112 is limited from the sliding bush 114. In particular, it is with such training also possible, the pistons 111, 112 from outside into the recesses 45, 46th to limit screw-in plugs 133 in the extension movement from the sliding bush 114. Such plugs 133 are preferably screwed into the legs 17, 18 and hold the pistons 111, 112 in such a way that, on the one hand, they slide into the recesses 45, 46 engage and on the other hand are also guided in the sliding bush 114. By losing weight the plug 133 from the legs 17, 18 is then at least one piston 111, 112 removable and thereby also the support element 3 detachable from the ski 2.

Furthermore, it is possible for the anchoring elements 54, 55 to be integrated into the ski body To form bearing bushes 105, 106, as can be seen in particular from FIG. 6, the preferably opposite recesses 79, 80; 81, 82 via the inner guide hole, which is preferred for receiving and holding one continuous bearing pin 107, 108 or also for receiving two pistons 111, 112 is formed, connects. The support element 3 is then on the sports device 1 put on that the recesses 45, 46; 50, 51 with the inner bearing bores of the bearing bushes 105, 106 are aligned, whereupon the bearing bolts 107, 108 can be inserted are and articulate the support element 3 with the ski 2. At least one of the opposite recesses 45, 46; 50, 51 can be a blind hole Recess be formed, the at least one axial displacement movement the bearing pin 107, 108 limited. After inserting the bearing pin 107, 108 can be formed as a through hole recess 46; 51 with the stopper 133 are closed or the plug 133 can be inserted into the recess 46; 51 screwed in are so that falling out of the bearing pin 107, 108 excluded is. Preference is given by screwing in or inserting the plug 133 Bearing bolts 107, 108 fixed largely immovable in the axial direction.

Regardless of the training shown, it is of course also possible to assign the pistons 111, 112 to the legs 17, 18 and to extend and retract them to design and therefore extendable and retractable from the legs 17, 18 Bearing pin 47, 48 of a corresponding sliding bush 114, which in the ski body is integrated and may also be formed as a blind hole-like recess can assign. Such training would be equivalent to training represent the execution described in detail above.

The previous description is not based on the design of the anchoring element 54 limited in the front end region of the support element 3, but in a corresponding manner Way of course also to that assigned to the rear end region Anchoring element 55 can be transferred by assigning corresponding reference numerals.

8 and 9 is a further embodiment of the sports device 1 and the support element 3 connected to the ski 2 in the manner according to the invention, that stores the ski binding 6, shown. This will be for those previously described Parts used the same reference numerals, and previous descriptions are analogous to the same parts with the same reference numerals.

Here, the support element 3 is essentially over its entire longitudinal extent substantially U-shaped in cross-section, i.e. that of the central plate part 32 leg plates projecting essentially at right angles extend consistently over the entire length of the support surface 21 for the ski binding 6 or for the foot of the user forming plate part 32. The on both sides of the Plate part 32 protruding legs 17, 18; 19, 20 also extend over the Middle area 16 of the support element 3. In the mounting area of the support element 3 the ski 2 are in the side cheeks 83, 84 of the ski 2 the shape of the legs 17, 18; 19, 20 corresponding, continuous recesses 79, 80; 81, 82 arranged in which the legs 17, 18; 19, 20 of the support element 3 can be used in such a way that the outer surfaces 85, 86; 87, 88 essentially stepless or flush with the Complete side surfaces 89, 90 of side cheeks 83, 84. Front ends 134, 135 of the Support element 3 preferably close an acute angle with the support surface 21 a, i.e. the end face regions of the support element 3 in the end regions 14, 15 extend conically, starting from the running surface 27, in the direction of the support surface 21 expanding or are in side view - according to FIG. 8 - V-shaped boundary edges the leg 17, 18; 19, 20 in relation to the longitudinal direction - arrow 26 - of the ski 2 educated. The recesses 79, 80; 81, 82 in the longitudinal side areas of the ski 2 are chosen larger than the surface dimensions based on the side view according to FIG. 8 the continuous legs 17, 18; 19, 20, so that between the boundary edges the leg 17, 18; 19, 20 and the boundary edges of the recesses 79, 80; 81, 82 a free space is formed, the largely unimpeded deformation of the ski 2 relative to the support element 3. So are in particular between the ends 134, 135 and the boundary surfaces 99, 100 as well as between the longitudinal edges 136, 137 of the legs 17, 18 facing the tread 27; 19 20 and the lower boundary surface of the recesses 79, 80; 81, 82 open spaces 138, 139 formed, the deformation of the ski 2 a largely free mobility compared to the rigid support element 3 and therefore in particular represent a margin of compensation.

Of course, it is also possible to fill the free spaces 138, 139 with a filler to fill in, which has a comparatively easy deformability and fixing prevented by ice and snow in the free spaces 138, 139. Transversely to the longitudinal direction - Arrow 26 - the ski 2, the support member 3 is largely immovable the ski 2 stored. This can be done in particular through a largely game-free request of the inner surfaces 91 to 94 on the boundary surfaces 95 to 98 of the recesses 79 to 82 can be achieved.

The support element 3 with the ski binding 6 is supported by the integrated in the ski body Anchoring elements 54, 55 on the ski 2 or it is over this with the ski 2 connected. The bolt-like elements 65, 66 assigned to the end regions 14, 15 are preferably integrated into the ski body during the manufacture of the ski 2. A longitudinal extension of the bolt-like elements 65, 66 corresponds approximately to the width of the ski 2 in the assembly area for the ski binding 6, so that the end areas 14, 15 associated, preferably circular in cross section journal 47, 48; 52, 53 in the recesses 79, 80; 81, 82 protrude or beyond the boundary surfaces 95 to 98 of the recesses 79 to 82 protrude. The bearing journal firmly connected to the ski 2 47, 48; 52, 53 are corresponding recesses 45, 46; 50, 51 in the Legs 17 to 20 assigned. The recesses 45, 46; 50, 51 are outgoing from the boundary edges of the legs 17 to 20 like a slot in the leg plates incorporated. Longitudinal central axes 140, 141 which are slit-shaped in the legs 17 up to 20 recesses 45, 46; 50, 51 run when viewed a side region of the support element 3 substantially at right angles to each other. For example, the longitudinal central axis 140 of the recesses 45, 46 essentially parallel to the tread 27, whereas the longitudinal central axis 141 of the further slot-shaped Recesses 50, 51 substantially perpendicular to the running surface 27 or is aligned perpendicular to the support surface 21. The dimensions of the slit-shaped Recesses 45, 46 are selected such that the support element 3 over the bolt-shaped Element 65 is guided on the ski 2 with as little play as possible in the vertical direction Longitudinal direction - arrow 26 - the ski 2 is relatively displaceable. The dimensions the further slot-shaped recesses 50, 51 in the end region 15 are of this type chosen that the support element 3 related to the longitudinal direction - arrow 26 - of the ski 2nd is fixed immovably. The support element 3 is supported via the recesses 45, 46; 50, 51 with respect to a vertical direction each rigidly on the bearing journal 47, 48; 52, 53 from.

The slot-shaped recesses 45, 46; 50, 51 are preferred by means of their own Machining process in the legs 17 to 20 of the substantially U-shaped Profiles incorporated, the recesses 45, 46 starting from the front end 134 of the support element 3 extending in the longitudinal direction of the support element 3 in the legs 17, 18 are incorporated or milled. The slot-shaped recesses 50, 51 in the end region 15 of the support element 3 are starting from the longitudinal edges 136, 137 machined or milled into the legs 19, 20 perpendicular to the support surface 21.

Due to the previously described design of the support element 3 and the recesses 45, 46; 50, 51 is this in a simple manner on the bearing journal 47, 48; 52, 53 mountable on ski 2. For mounting the support element 3 with the ski binding 6 on the ski 2 is for the time being the end region 14 with the ski 2 in To put operative connection and then the end region 15 with the bolt-shaped To put element 66 in operative connection. For this, only the journals are 47, 48 to be introduced into the recesses 45, 46 and subsequently the recesses 50, 51 to engage with the journals 52, 53 or the end region 15 the bearing pins 52, 53 put on.

For secure connection of the support element 3 to the ski 2 is at least one Recess 50, 51 is a locking member 142 that can be operated by the user of the sports device 1 assigned that optionally blocks an opening 143 of the recesses 50, 51. at deactivated blocking member 142, opening 143 of recesses 50, 51 is released, whereby the journals 52, 53 are inserted or removed from the recesses 50, 51 these can be removed. The user of the sports device 1 the blocking member 142 are activated, whereby the opening 143 is closed and separation of the support element 3 from the bearing pins 52, 53 is prevented. When activated Locking member 142 is the end region 15 of the support element 3 articulated with the Sports device 2 connected, with translational movements between the end region 15 of the support element 3 and the ski 2 are largely prevented.

The locking member 142 is in the embodiment shown by a in the longitudinal direction - According to arrow 26 - movable locking bolt 144 is formed. The one with a handle 145 by the user of the sports device 1 movable locking bolt 144 is in a guide bore 146 in at least one leg 19, 20 of the support element 3 slidable in the longitudinal direction of the support element 3. The locking bolt 144 of the locking member 142 is preferred via a resilient biasing device 147 in that Pushed to the end position, in which the lifting element 3 is prevented from being lifted off the ski 2 is. About this spring-elastic biasing device 147, which is preferably by a Compression spring 148 is formed, the locking bolt 144 is in the rest or normal state held in that end position in which the opening 143 of the slot-shaped Recess 50, 51 is closed. When moving the locking bolt 144 by means of the handle 145 against the force of the biasing device 147 End region of the locking bolt 144 facing away from the compression spring 148 out of the recess 50, 51 removed, thereby opening 143 of recess 50, 51 completely is released and the support element 3 can be lifted off the bearing pins 52, 53 can. The bearing devices 22, 23 can then also be located in the front end region 14 of the support element 3 and the support element together with the ski binding 6 be removed from the ski 2.

A possible displacement path of the locking bolt 144 is chosen to be at least the same size like a protrusion of the locking bolt 144 from the guide bore receiving the compression spring 148 146 related to the blocking position of the blocking member 142. The longitudinal axis the guide bore 146 extends essentially at right angles to the longitudinal central axis 141 of the recess 50, 51.

The guide bore 146 is preferably in the longitudinal direction starting from the front end 135 of the support element 3 incorporated into the legs 19, 20 and crosses the slot-shaped recess 50, 51. The locking bolt 144 is over the handle 145, which can preferably be screwed to the locking bolt 144 against falling out the guide bore 146, which runs essentially parallel to the running surface 27, is secured, the handle 145 protrudes radially from the locking bolt 144 and the displacement path of the locking bolt 144 via an elongated guideway 149 for the handle 145 is set. The longitudinal extent of the guideway 149 runs parallel to the longitudinal central axis of the guide bore 146 for the locking bolt 144. In the end regions the guideway 149 for the handle 145 can - as indicated schematically - In each case a branch running perpendicular to the displacement path of the locking bolt 144 be provided in the guideway 149, which a locking of the locking bolt 144 at the respective position of the junction by reaching behind with the Handle 145 enables. In particular, by turning the locking bolt radially 144 at the respective positions at which such a detent or branch is formed in the guideway 149, a hooking of the handle 145 with this locking lug possible, whereby the locking bolt 144 held in place becomes. When the handle 145 swings back again into the guide track 149 the locking bolt 144 is automatically in the locking position via the pretensioning device 147 crowded. In this locked position of the locking bolt 144 can also Latch or a branch in the guide path 149 may be provided, the one automatic displacement of the locking bolt 144 against the spring force in the release position of the blocking member 142 prevented. The combined, translational and rotary Movement of the locking bolt 144 over the handle 145, which over the guideway 149 is predefined, with or without the action of a pretensioner 147 be realized.

The adjusting movements of the locking member 142 are the adjusting movements of the Locking pistons of firearms similar.

The previous description therefore again forms a releasable connecting device 128 between a ski binding 6 or between a support element 3 for a ski binding 6 and a ski 2, which can also be used by any user can be activated and deactivated by laypersons in the shortest possible time while doing the usual Binding assembly to be carried out by experts using screw connections replaced.

The two anchoring elements 54, 55 are in turn each in the neutral Zone or in the neutral layer - level 58 - of the ski body, which at Bending stresses directed perpendicular to the running surface 27 are formed in the ski body is. The anchoring elements 54, 55 can be used for highly rigid fixing in the Ski body in turn be provided with projections 63, 64, which are substantially parallel run to the tread 27.

The support element 3 is preferably made of an extruded profile made of aluminum, aluminum alloys, plastics or fiber-reinforced plastics formed with high bending strength and torsional rigidity. Each side cheek is preferred 83, 84 of the ski 2 are assigned a locking member 142 which holds the support element 3 connects on each long side with the trunnions 52, 53 so that they cannot come off and thereby the torsional rigidity of the support element 3 or the entire sports device 1 is increased.

As can be seen in particular from FIG. 9, the indentations or the recesses 79 to 82 for the legs 17 to 20 of the support element 3 directly from the material the hard outer shell 70, i.e. the recesses 79 to 82 in Ski bodies are already in the manufacture of the ski 2 by a one-piece Shell 70 with corresponding recesses in the mounting area for the support element 3 formed, whereby a ski structure uniformly covered by the shell 70 is given which reliably prevents liquids from penetrating into the skis.

Of course, it is also possible for after the manufacture of the ski 2 in the Shaped recesses 79 to 82 for optimal water tightness Obtain by coating their surfaces with a waterproof and / or elastic Coating such as Varnish to be coated later.

10 shows another embodiment variant of an anchoring element 54, the is designed for the subsequent determination of the same in the ski body and e.g. to Serves a support element according to FIG. 8 on a ski. This bolt-shaped Element 65 has the thread arrangement in the central region on its outer circumference 129 on and in the end regions related to its longitudinal direction a journal 47, 48 formed with a circular cross section. In the forehead of the bolt-shaped element 65 can blind-hole-like locking elements 150 with polygonal cross-section are formed, over which the bolt-shaped element 65 can be connected to a corresponding tool and can be rotated , wherein the locking element 150 absorb a relatively high, mechanical torque can. The locking element 150 can e.g. square or hexagonal Have a cross-section and the tool can e.g. formed by an Allen key over which corresponding torque on the bolt-shaped element 65 can be transferred. About this latching element 150 is the bolt-shaped Element 65 can be coupled with the appropriate tool and via the thread arrangement 129 can be screwed into a suitably prepared through hole in the ski body. The through hole extends from one side cheek of the ski to the opposite Sidewall and runs essentially parallel to the tread and transverse to the longitudinal direction of the ski. A diameter of this through hole is such chosen that the threaded arrangement 129 of the bolt-shaped element 65 in the The body engages and after it has been screwed in, it is tear-proof in the body holds.

11 shows a further embodiment variant of a largely fully automatic Connection device 128 between the ski binding or the support element 3 for the ski binding and the ski 2. In addition, further training is the Locking device 142 on the connection device 128 for preventing arbitrary Loosening the support element 3 from the ski 2 shown. Here, the blocking member 142 a pawl 151 which is about an axis 152 which is parallel to the pivot axis 57 of the bearing pin 52 extends, is pivotally mounted. The pawl 151 engages behind in the locked position of the locking device with a locking lug 153 that of the opening 143 of the bearing pin 52 assigned to the recess 45. This pivotally mounted pawl 151 is preferably via the pretensioner 147, which is preferably formed by a compression spring 148, in the normal state pushed into the locked position in which the bearing pin 52 of the detent 153 of the Pawl 151 is engaged and the support element 3 relative to the bearing journal 52 fixed immovable, but rotational movements around the bearing pin 52 or around the pivot axis 57. The pawl 151 is preferably with the handle 145 provided that the pawl 151 can be pivoted comfortably allows the action of the biasing device 147 about the axis 152, then the locking lug 153 is moved out of the area of the recess 50 and thus the Carrier 3 releases from ski 2.

The angle enclosed by the locking lug 153 between its boundary edges is preferably less than 90 ° or the detent 153 is formed at an acute angle, so that when the pawl 151 hits the bearing pin 52, this example is pivoted automatically counterclockwise and after complete Inserting the bearing pin 52 into the recess 50, the pawl 151 automatically springs back and thus the locking member 142 automatically in the locked state added. The formation of such a pivotable pawl 151 with a acute-angled locking lug 153 engaging behind the bearing journal 52 in the locked state thus enables a fully automated locking of the support element 3 on the ski 2, with the support element 3 simply being clicked onto the ski 2. This fully automatic "Click-in system" for the support element 3 with the ski binding for fixing the ski 2 is of course also in all of the previously described exemplary embodiments applicable.

When the locking member 142 is in the locked state, one that engages behind the bearing journal 52 runs Locking edge 154 of the locking lug 153 is substantially perpendicular to the longitudinal central axis 141 of the slot-shaped recess 50 and thus blocks the opening 143 thereof.

Optionally, the handle 145 or the pivotable pawl 151 also locking means are associated with the unintentional pivoting of the pawl excludes when driving the sports device 1.

The pivot axes of the axis 152 and the pivot axis 57 of the bearing pin 52 lie thereby approximately on the longitudinal central axis 141 of the recess 50 or in the extension the same.

12 and 13 is a further embodiment of the invention Ski 2 or the sports device 1 according to the invention shown, whereby for previous parts already described the same reference numerals are used.

Here, the support element 3 is also formed in several parts, in particular in two parts, the separating and / or joining area 35 here transverse to the longitudinal direction - arrow 26 - the ski 2 or the support element 3 extends approximately in the central region 16 thereof. The support element parts 11, 13 thus formed are in turn via a Connection device 12, in particular via a telescopic guide arrangement 155, in the separating and / or joining area 35 connected to one another in a form-fitting manner and form thus the support element 3. The guide arrangement 155 enables a relative displacement of the two support element parts 11, 13 in the longitudinal direction - arrow 26 - to each other apart as well. In the other spatial directions are the two support element parts 11, 13 immovably fixed to one another via the guide arrangement 155. The in the illustrated embodiment in the central region 16 of the support element 3 between the two support element parts 11, 13 formed guide arrangement 155, can thereby by any leadership training known from the prior art be formed between two profile parts. For example, the support member 11 such be designed such that it at least partially surrounds the support element part 13 on the outside and thus the supporting element part 13 can be pushed into and out of the supporting element part 11. Furthermore, as shown schematically, the support element part 13 on the support element part 11 facing end region a guide extension 156 with a circular or have polygonal cross-section, which in a corresponding guide recess 157 in the second support element part 11 with a corresponding cross section can be introduced. In the two refer to the longitudinal direction - arrow 26 - of the ski 2 End regions 14, 15 of the support element 3 are the coupling parts 4, 5 of the Ski binding 6 is mounted in a longitudinal guide device 158, 159, respectively.

The longitudinal guide devices 158, 159 hold the coupling parts 4, 5 on the support element 3 and thereby allow an adjustment thereof in the longitudinal direction - arrow 26 - of the ski 2 relative to the support element parts 11 and 13. In particular, the coupling part 4 mounted on the support element part 11 via the longitudinal guide device 158 and optionally in the longitudinal direction - arrow 26 - adjustable relative to this. Analogous for this purpose the coupling part 5 is on the support element part via the longitudinal guide device 159 13 stored and relative to the support member part 13 in the longitudinal direction - according Arrow 26 -, guided by the longitudinal guide device 159, adjustable. The longitudinal guide devices 158, 159 thus allow adjustment of the coupling parts 4, 5 in the longitudinal direction - according to arrow 26. In the other spatial directions are the coupling parts 4, 5 largely immobile. The one in particular as a toe a safety ski binding designed coupling part 4 is via a connecting member 160 with the in particular as a heel automat of a safety ski binding trained coupling part 5 connected. That connecting the two coupling parts 4, 5 Connecting member 160 can be, for example, a connecting rod or a connecting band can be formed in a rigid or flexible design. The liaison body 160 is, however, particularly designed to be stretch-resistant, so that the over Connecting member 160 interconnected coupling parts 4, 5 in the Link 160 certain distance from each other can be held. Possibly can the connecting member 160 via an adjusting and / or locking device 161 be formed variable in length to the distance between the coupling parts 4, 5 to be able to change and thus the ski binding 6 to different shoe sizes to be able to adapt in a simple way.

At least one coupling part 4 or 5 is over the adjustment and / or locking device 161 can be fixed immovably relative to the respective support element part 11 or 13. In the exemplary embodiment shown, the coupling part 4 or the front jaw is Via the adjusting and / or locking device 161 optionally with the support element part 11 set in its relative position to this. The adjustment and / or Locking device 161 has an actuating member 162, via which the coupling part 4 in relative positions relative to the longitudinal direction - arrow 26 Support element part 11 can be fixed, so that this is activated when the locking device the desired position is fixed immovable. The coupling part 5 is connected in motion to the coupling part 4 via the connecting member 160 and remains floating in the longitudinal guide device 159. About the The user of the sports device 1 can therefore adjust and / or lock the device 161 the relative position of the entire ski binding 6 relative to the ski 2 or to the support element 3 change, the distance between the two corresponding to the shoe size Coupling parts 4, 5 unchanged by the strain-resistant connecting member 160 is retained. The actuator 162 acts with a locking pin or Like. Together, which optionally the adjustment of the actuator 162 Coupling part 4 with the support element 3 or with its longitudinal guide device 158 connects motionally.

The support element part 11 includes the support surface 21 in the direction of the underlying Ski 2 directed legs 17, 18 corresponding to the width of the ski 2 Are spaced from each other. The end regions facing the ski 2 the legs 17, 18 are connected to the ski 2 via the bearing devices 22, 23 hinge-linked. The hinge connection 44 in the end region 14 of the support element part 11 with the ski 2 comprises connecting elements in the exemplary embodiment shown 163, in particular formed by a pair of fastening screws 164, 165 are screwed into the anchoring element 54 or 55 integrated into the ski body are.

The anchoring element 54, 55 extends continuously between the two Side surfaces 89, 90 of side cheeks 83, 84 of ski 2. Close accordingly the ends of the anchoring elements 54, 55 are flush with the side surfaces 89, 90 of the ski 2. The legs 17, 18 lie with their inner surfaces 91, 92 over the entire surface on the side cheeks 83, 84 and on the end faces of the anchoring element 54, 55 on. To produce the articulated connection 44 between the support element part 11 and the ski 2 pass through the connecting elements 163, in particular the fastening screws 164, 165, each have a leg 17 via the recesses 45, 46, 18 and are rigid with the end regions of the anchoring element 54, 55 and securely connected. The across the side cheeks 83, 84 of the ski 2 across Longitudinal direction - arrow 26 - the same and substantially parallel to the tread 27 in the two anchoring elements spaced apart in the longitudinal direction - arrow 26 54, 55 screwed-in or screw-in fastening screws 164, 165 form the journals 47, 48 for the articulated mounting of the support element part 11 out. The fastening screws 164, 165 are after fastening the Support element part 11 fixed against rotation and form, as I said, in one Screw head facing shaft part, the journal 47, 48 from. The shaft part of the Fastening screws 164, 165 preferably have a larger diameter than the threaded section of the fastening screws facing away from the screw head 164, 165. The screw heads of the fastening screws 164, 165 allow in conjunction with the threads, the legs fit snugly 17, 18 on the side surfaces 89, 90 of the ski 2 and prevent the Legs 17, 18 from the journal 47, 48.

In the front end region 14 of the support element 3, the legs 17, 18 form a pair of legs and in the rear end region 15 related to the direction of travel - arrow 26 the legs 19, 20 also form a pair of legs, each of which extends to the underlying one Ski 2 extend and with attached support element 3 each directly to the Sidewalls 83, 84 abut. The assigned to each pair of legs in the ski 2 integrated anchoring elements 54, 55 each lie in the neutral zone or in the neutral layer - level 58 - of the ski 2 when it is perpendicular to the tread 27 directional bending stresses.

Furthermore, the anchoring elements 54, 55 are on a common, in Sandwich element 7 integrated anchoring layer 166 arranged. These are the anchoring elements 54, 55 receiving or interconnecting, plate-shaped Anchorage layer 166 is with its two large flat sides in the aligned substantially parallel to the tread 27. A longitudinal extension of the anchorage layer 166 runs parallel to the longitudinal direction - arrow 26 - approximately over the entire Length of the support element 3 or over the entire binding assembly area of the ski 2. The anchoring layer 166 is in the neutral layer or in the neutral fiber - level 58 - the ski 2 arranged. The neutral layer of the ski 2 - Level 58 - runs parallel to the tread 27 over the entire length of the as Composite ski 2 and is essentially parallel to the tread 27 of the ski 2 aligned, provided that it is perpendicular to the tread 27 Bending stress is exposed.

There is a difference from the exemplary embodiments described above here in that the two pairs of legs or respectively the legs 17, 18 and Legs 19, 20 in the two mutually spaced end regions 14, 15 each a joint 44 on the side cheeks 83, 84 with the ski 2 articulated are connected and the required for a free formability of the ski 2 longitudinal compensation device is formed directly on the support element 3 by this at least comprises two support element parts 11, 13, which is directed in the longitudinal direction - arrow 26 Guide assembly 155 are relative to each other. In the Longitudinal direction - arrow 26 - acting guide arrangement 155 is at least over realized two support element parts 11, 13, the two support element parts 11, 13 each articulated with the ski 2 via an articulated connection 44 with transverse to Longitudinal direction - arrow 26 - running and substantially parallel to the tread 27 aligned pivot axes 56, 57 are connected to the ski 2.

Instead of the arrangement of the guide arrangement 155 in the central region 16 of the support element 3, it is also possible to only use both coupling parts 4, 5 of the ski binding 6 to arrange a support element part 11 and thus guide arrangement 155 e.g. in the To provide end portion 15 of the support member 3. The connecting element can then be used 160 omitted and both coupling parts 4, 5 can directly on the one support element part 11 be supported or carried by this. The longitudinal compensation Via the guide arrangement 155, the relative displacement of the Support element part 13 relative to the support element part 11, e.g. in the rear end area 15 of the support member part 13.

If necessary, it is also possible to mount the bearing devices 22 to 25 via support nocks To reinforce 167 to 170. These support cams 167 to 170 are from the inner surfaces 91 to 94 of the legs 17 to 20 or from the bottom 31 of the support element 3 and form a linear support surface on the top 30 of the ski 2. Additional support of the support element part is thus provided via these support cams 167 to 170 13 on the top 30 or on the top cover layer or shell 70 of the ski 2 achieved. The line-shaped contact surfaces between the ski 2 and the support cams 167 to 170 arranged on the support element 3 are supported by support bodies achieved with an arcuate lateral surface, the surface of the ski 2 or the top layer of the ski 2 tangential to the lateral surfaces of these support cams 167 to 170 runs. The contact surface is essentially vertical over the Pivot axes 56, 57 arranged. The support cams 167 to 170 result in a direct, low-loss power transmission from the support element 3 to the running edges 71, 72 of the Schis 2, since this the force effect directly on the legs of the shell 70 on the Forward running edges 71, 72. See impairments in the articulation 44 the support element 3 and the ski 2 are of appropriate dimensions or negligible with correspondingly soft support cams 167 to 170 but still a stabilization of the connecting device between the support element 3 and the ski 2 as well as an instantaneous introduction of force into the ski 2 and vice versa.

The anchoring elements 54, 55 have a cross-section, i.e. transverse to the longitudinal direction - Arrow 26 - considered the ski 2, a polygonal, e.g. square cross section on, but can also take circular or any other cross-sectional shapes. The anchoring elements 54, 55 can in turn in the core 8 of the Ski 2, which can be made of wood or other core building materials, integrated become or is the anchoring layer receiving the anchoring elements 54, 55 166 set in the Schikern.

If necessary, the plate-shaped anchoring layer 166 penetrates the block-like ones Anchoring elements 54, 55 via slot-shaped openings arranged in them with a corresponding cross-section, so that the distance between the two anchoring elements 54, 55 to each other by merely moving them on the reinforcement layer 166 adjusted before their embedding different lengths of support elements 3 can be.

In summary, it can be stated that the support element 3 for the Ski binding 6 in each of its end regions 14, 15 on the integrated in the ski body and in the neutral zone - level 58 - of the same anchoring elements 544, 55 or anchoring layers 166 is supported or connected to these. Of further the support element 3 for receiving several coupling parts 4, 5 is the Ski binding 6 in the decentralized, approximately corresponding to the length of the shoe, to each other distanced areas with the ski 2 attached to the side cheeks 83, 84.

For the sake of order, it should finally be pointed out that for better understanding the construction of the sports device 1 this or its components, sometimes to scale and / or enlarged and / or reduced.
