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

AT 410 758 B

The invention relates to a ski, in particular an alpine ski, with a plurality of layers arranged between a tread surface and a cover layer, which form at least one sandwich element with a core arranged between the layers and the ski has anchoring elements spaced apart in the longitudinal direction, which are essentially transverse to the longitudinal direction and run essentially parallel to the running surface of the ski and, starting from the side cheeks of the ski, are provided for holding a ski binding mounted on a support element.

From DE 41 12 299 A1 a ski with a carrying device for a ski binding is known. The support device supporting the coupling parts of the ski binding is articulated in the central region thereof via an axis running transversely to the ski longitudinal direction, so that a pivoting of the support device together with the ski binding around this central axis is made possible. Between the ski and the support device, resilient support elements are arranged in the area in front of the axis and in the area behind the axis, which provide a defined resistance to the pivoting movement of the support device relative to the ski. The disadvantage here is that the swiveling movements of the support device for the ski binding caused by loads relative to the ski can sometimes lead to roll tendencies or difficulties in keeping the balance for the user. Furthermore, the forces to be transmitted by the user to the sports device, in particular the forces acting in the vertical direction, are delayed, making precise control of the ski difficult.

Furthermore, a ski with a binding support plate is known from DE 21 35 450 A. This binding support plate is connected to the ski by means of bearing devices which are spaced apart from one another in the longitudinal direction of the ski and fixed on the upper side thereof. One of the bearing devices forms an articulated connection between the binding support plate and the ski and the further storage device forms an articulated and guiding device between the binding support plate and the ski. The disadvantage here is that the bearing devices for the binding support plate attached to the top of the ski cannot withstand the forces occurring during ferry operation, or the desired, unaffected elasticity or deformability of the ski cannot be achieved with large-sized bearing devices.

WO 93/12845 A2 shows, inter alia, a ski with a plate-shaped mounting element for the coupling parts of a ski binding. The coupling element for the ski binding is formed by a relatively hard plate, which is connected to the ski body with the interposition of a damping layer. The connection is designed such that the mounting element supported against the ski body via the damping layer can be moved at least in its front and rear end region relative to the ski body in its longitudinal direction. For this purpose, it is proposed, inter alia, to provide recesses in the side cheeks of the ski or openings which penetrate the two side cheeks and which are filled with the damping material and thereby embed a transverse bolt. Due to the transverse bolts embedded in the damping material for holding the mounting element, the desired “floating bearing” should the mounting plate can be reached relative to the sports equipment. Independently of this, according to a further embodiment, it was proposed to provide separate mounting plates for the damping support of the front and rear jaws and thus to provide separate mounting pots for the front and heel jaws for damping mounting relative to the ski. In order to avoid an unfavorable increase in the distance between the toe and the buttocks due to the damping or compliant mounting of the mounting plates perpendicular to the tread and also in the longitudinal direction of the ski, a connecting means or a band is also provided which connects the two mounting plates supported directly on the top of the ski and thereby prevents an increase in the distance between the front and rear cheeks. This band between the mounting plates for the front and rear jaws thus counteracts a 4b increase in size between the front and rear jaws if the user of this device e.g. humps or other obstacles are overcome when driving downhill and the ski is more slowly decelerated compared to the binding unit, in particular compared to the toe. With this connecting means or band, an unintentional falling out of the ski binding or a short-term loosening of the ski boot with respect to the ski binding can be prevented and the contact pressure of the front and rear cheeks on the ski boot can be secured. 2

AT 410 758 B

The disadvantage here is that the proposed mounting of the mounting elements for the ski binding delays the transmission of the steering forces to be exerted by the skier to the longitudinal side edges of the ski body and consequently the control behavior of the ski acts sluggishly. In addition, the edge grip is reduced, which affects especially the driving behavior on hard slopes. Furthermore, it is disadvantageous that the recesses or breakthroughs in the ski body which are relatively large-flowered for extensive embedding represent a significant weakening of the ski body. The bending characteristic of the ski will therefore have considerable drops in the area of the recesses provided with the damping material and the transverse bolts, as a result of which such a ski has relatively high tendencies to vibrate or so-called flutter, and the driving behavior is thereby additionally negatively influenced. In addition, the recesses in the ski body, which are provided with the damping material and are thus inherently flexible, represent significant weaknesses in strength and lead to overloading of the ski primarily to break points starting from these recesses in the ski body.

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

This object of the invention is achieved in that the support element is constructed in several parts, in particular in two parts, a separating and / or joining area between the support element parts running transversely to the longitudinal direction of the ski and the two support element parts each having an articulated connection with transverse to the longitudinal direction and in substantially parallel to the tread pivot axes are articulated to the ski and a coupling part of the ski binding is mounted for each support element part, wherein a connecting device between the two support element parts comprises a guide arrangement by means of which the support element parts are longitudinally displaceable relative to each other. A resultant advantage lies in the fact that the structure of the ski for assembling the ski binding remains completely unchanged and therefore the parameters which the manufacturer considers the most favorable, such as the bending characteristic, the bending stiffness distribution and the breaking strength are retained even after the binding has been installed. Any mechanical processing of the ski body, such as e.g. Machining by drilling holes in the ski body, or chemical processing, such as No gluing. The mechanical processing has always resulted in a change in the characteristic values, e.g. the flexibility of the ski, which can be clearly recognized and registered with suitable measuring equipment. These disadvantageous effects are now largely eliminated by the claimed training. The decoupling of the longitudinal guide device from the joint arrangement, i.e. the joint arrangement and the guide device are separated from each other in terms of area, and also enables larger joint and guide parts.

Due to the advantageous development according to claim 2 or 3, the guide device is formed between the two large-area support element parts, so that the surface pressure between the guide parts of the guide track is very low and thus wear and tear are excluded even during hard and long-term operation.

The advantageous embodiment according to claim 4 prevents tension and changes in the safety-relevant trigger values between the coupling parts of the ski binding that hold the shoe when the ski is deformed or bent.

An embodiment according to claim 5 is advantageous, since it achieves anchoring of the ski binding that is secure against tearing out, without having any significant influence on the ski parameters.

According to an embodiment, as described in claim 6, a high-strength connection between the ski and the support element is possible, and the components required for this can be produced relatively simply and inexpensively.

In this case, an embodiment according to claim 7 proves to be advantageous, since the ski binding is thereby reliably held even with very high forces and undesired positional deviations thereof are excluded.

According to an advantageous further development according to claim 8, 3

AT 410 758 B different relative positions of the ski binding in relation to the ski.

However, an embodiment according to claim 9 is also advantageous, since as a result the usual waistline or the usual course of the width of the ski can be maintained and the relatively far apart support points of the ski binding on the ski result in favorable force relationships.

According to claim 10, the width of the ski is not changed by the installation of the ski binding or the support element for the ski binding. In addition, abrupt variations in width, referring to a top view of the ski, are avoided and harmoniously extending boundary edges of the ski body that increase the overall visual impression are achieved.

In the embodiment according to claim 11, the anchoring element can be embedded in the core of the ski in a simple manner. An embodiment according to claim 12 is possible since the fixing of the anchoring elements in the relatively solid and large-volume core of the ski body achieves reliable and highly stable fixing of the anchoring elements in the ski body.

The advantageous embodiments according to one or more of claims 13 to 15 enable the ski binding or the support element for the ski binding to be reliably fixed on the ski, with the connecting elements providing a releasable connection on the one hand and the prestressing between the parts to be connected in addition easily regulated and can also be changed at a later date.

The embodiment according to claim 16 is also advantageous, since this results in an elevated contact position of the foot or shoe of the user, which enables strong inclinations when cornering with the sports equipment without touching the ground with the shoe.

However, an embodiment according to claim 17 is also advantageous, since the deformation movements of the ski caused by driving through undulating terrain are thereby made possible without hindrance and stiffenings in areas, especially in the binding assembly area of the ski, are therefore avoided.

An embodiment according to claim 18 is also advantageous, since it enables the support element to be mounted very easily on the ski, and the high-strength design of the ski enables the construction of a highly stable and reliable connecting device for the two support element parts.

However, a further development according to one or more of claims 19 to 21 is also advantageous since this enables the ski binding or the support element for the ski binding to be fixed quickly and easily. In addition, the support element or the ski binding can be released from the ski particularly easily at any time and without great effort.

With the advantageous embodiment according to one or more of claims 22 to 25, a particularly simple and largely automated fastening process of the ski binding or of the support element for the ski binding on the ski is achieved.

Due to the advantageous embodiment according to one or more of claims 26 to 34, a system for mounting a binding or a support element on a ski is created, which has a high reliability and significantly shortens the assembly process of the ski binding on the ski, that is, disassembly at any time the same without the use of tools.

Further advantageous developments are described in claims 35, 36, since in this way the harmonious course of the characteristic curve of the flexural rigidity distribution of the ski is retained despite the high-strength anchoring elements.

In the advantageous embodiment according to claim 37, the anchoring element is formed in one piece in the ski body and, due to the preferably metallic material, has good prerequisites for mounting the support element or for mounting the ski binding.

With the training according to claim 38, the usual outline shape of the ski is hardly changed and a harmonious appearance is created. In addition, hooks between support element parts or between the legs of the two support element parts of a pair of skis are ruled out in the case of skis with little waisted, which enables undisturbed ferry operation.

Furthermore, a training is possible, as described in claims 39 and / or 40, since this also makes the articulation points the relatively large and dimensionally stable parts of the support

AT 410 758 B element can be assigned and the legs for mounting the ski binding or the support plate for the ski binding can be connected to the ski so that they cannot move. The joint device as well as the joint and guide device can then be formed in the end regions of the plate part between the latter and the legs firmly connected to the ski.

An embodiment according to claim 41 is also advantageous, since the surface pressure in the ski body can thereby be greatly reduced and the stress on the individual components is particularly low.

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

AT 410 758 B

Wood, in particular from a plurality of lamellae 9, 10 which are glued to one another and thus connected to form a one-piece component and which are preferably formed from hardwood.

The support element 3, which is essentially U-shaped in cross section, is in this case of multiple parts, preferably of two parts, with a first support element part 11, which is essentially L-shaped in cross section, via a connecting device 12 with a further support element part 13, which is also essentially L-shaped in cross section 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 present in this exemplary embodiment at least in end regions 14, 15 thereof, whereas the cross section of the support element 3 in an intermediate region 16 essentially corresponds to the cross section of a plate-like component. Accordingly, 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 the ski 2 arranged below a support surface 21 on the support element 3 for the foot of the user.

The legs 17, 18 which are assigned to the front end region 14 and are spaced apart from one another approximately at a distance corresponding to the width of the ski 2 have bearing devices 22, 23 in an end region which faces away from the support surface 21 for the foot of the user and by means of which the support element 3 is attached the sports device 1, in particular can be connected to the ski 2. Likewise, the legs 19, 20 of the support element 3, which are assigned to the end region 15 of the support element 3 and are likewise spaced from one another approximately in the width of the ski 2, have bearing devices 24, 25 in their lower end regions facing away from the support surface 21 for connection to the sports device 1, especially with the ski 2.

The support surface 21 on the support element 3, which in plan view of the sports device 1 is essentially rectangular and in its longitudinal extent essentially parallel to a longitudinal direction - arrow 26 - of the ski 2 and essentially parallel to a tread 27 of a tread surface 28, has in this embodiment in its corner areas each have a leg 17 to 20 directed towards the underlying sports device 1, which fix the support surface 21 at a distance 29 above an upper side 30 of the ski 2. On an underside 31 of a substantially flat central plate part 32, which forms the support surface 21, of the support element 3 assembled via the connecting device 12 to form a one-piece component, a leg 17 to 20 is formed in each of the four corner regions, which is essentially at right angles from the underside 31 protrude from the plate part 32 and are connected to the ski 2 in their end region facing the tread 27 via a respective bearing device 22 to 25. The underside 31 of the central plate part 32 of the support element 3 is by an appropriate arrangement of the bearing devices 22 to 25 in the legs 17 to 20 and / or by an appropriate choice of the connection points with the ski 2, based on the vertical direction and / or by an appropriate choice the length of the legs 17 to 20 at a distance 33 above the top 30 of the ski 2, so that a free space 34 is formed between the support element 3, in particular between the central plate part 32 receiving the legs 17 to 20 and the top 30 of the ski 2 which allows the relative movements between the ski 2 and the support element 3, which will be explained in more detail below. The free space 34 between the underside 31 of the support element 3 and the top 30 of the ski 2 is given over the entire length and width of the plate part 32 between this and the top 30 of the ski 2.

At least in the end regions 14, 15, the support element 3 is thus essentially U-shaped in cross section, the plate part 32 forming the support surface 21 for the user's foot and in the corner regions the legs 17 to 20 are preferably formed in one piece in accordance with the preceding description ,

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

A separating and / or joining area 35 between the two cross-sectionally substantially L-shaped support element parts 11, 13 runs in the longitudinal direction - arrow 26 - of the ski 2 and essentially parallel to the running surface 27. In the separating and / or joining area 35, the Support element parts 6

AT 410 758 B 11, 13 can be assembled or separated from one another to form a one-piece support element 3 via the connecting device 12. Leg plates 36, 37 of the support element parts 11, 13 that face each other and extend in the longitudinal direction - arrow 26 - are additionally connected to one another in a form-fitting manner. The mutually facing leg plates 36, 37 of each substantially L-shaped support element part 11, 13 thus form the essentially flat, multi-part plate part 32 of the support element 3 in the assembled state. Corresponding recesses 38, 39 are provided in the mutually facing longitudinal edge regions of each leg plate 36, 37 for the positive connection of the two support element parts 11, 13, which enable a mutual positive connection.

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

The form-fitting connection between the two support element parts 11, 13 oriented in the longitudinal direction - arrow 26 - of the ski 2 in the separating and / or joining area 35 in between can also be formed by a tongue and groove connection, as is shown schematically in FIG. 2 , For this purpose, the indentations 38 of the horizontally oriented leg plate 36 are designed such that a spring 42 is formed in the longitudinal edge region facing the other support element 13. This spring 42 is dimensioned such that it can engage in a form-fitting manner in a groove 43 assigned to it in the leg plate 37 of the other support element part 13. 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 are connected to one another via the fastening means 40, in particular via the screws 41, in such a way that a relative movement between the two support element parts 11, 13 is prevented.

Of course, it is also possible to connect the support element parts 11, 13 to one another without the use of independent fastening means 40. Here, the support element parts 11, 13 are preferably non-detachably coupled to one another via snap connections. Such snap connections are known from the prior art and can e.g. be formed by a latching list running in the longitudinal edge region of the support element part 11 with an essentially circular cross-sectional shape and by a latching recess machined in the longitudinal edge region of the further support element part 13 with an essentially opposite, pan-shaped cross-sectional shape. Both support element parts 11, 13 are to be fed to one another for mounting the support element 3 or the ski binding 6 on the ski 2 and are permanently connected to one another by applying a corresponding pretensioning force. By applying or exceeding this pretensioning force, the locking bar then jumps into the locking recess, as a result of which the snap connection between the two support element parts 11, 13 is established. Such a snap connection is possible in a simple manner, in particular in the case of materials with a sufficient modulus of elasticity, in particular in the case of plastics or fiber-reinforced plastics or composites.

The supporting element parts 11, 13 are thus connected by the non-positive and / or positive connection via the connecting device 12, which comprises fastening means 40 and / or positive connections, to the one-piece supporting element 3, which overall has a high dimensional stability. The support element 3, which is two-part by the two support element parts 11, 13 but is combined to form a one-piece component via the connecting device 12, has in particular high torsional and flexural rigidity, which all the torsional and bending forces usually acting on the support element 3, such as these during ferry operation the sports device 1 can withstand. Due to the high torsional and bending stiffness of the support element 3, the coupling parts 4, 5 of the ski binding 6 remain completely unchanged in their relative position or relative position to one another under all operating conditions occurring in ferry operation, so that the pretensioning of the coupling parts 4, 5 of the ski binding 6 onto the shoe remains unchanged due to the absolutely bending and torsionally rigid or deformation-stable support element 3.

The support element 3 is in the end region 14 via an articulated connection 44 with the ski 27

AT 410 758 B coupled. This articulated connection 44 between the support element 3 and the ski 2 in the front end region 14 related to the direction of travel of the sports device 1 comprises 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 equipment 1 or to the ski 2 in a manner fixed against movement and have an essentially circular cross section, the diameter of which corresponds essentially to the diameter of the associated recesses 45, 46, so that a joint connection 44 between the support element 3 and the ski 2 that is as free of play as possible is ensured.

In the rear end region 15, which is distanced from the front end region 14 in the longitudinal direction - arrow 26 - of the ski 2, the support element 3 is articulated via a joint and guide device 49 to the sports device 1 or to the ski 2 and in the longitudinal direction - arrow 26 - des Skis 2 are relatively movable, in particular translationally displaceable and movable. This joint and guide device 49 between the support element 3 and the ski 2 in the rear or further end region 15 related to the direction of travel also includes recesses 50, 51, which in particular as elongated holes - arrow 26 - of the ski 2 pointing in the legs 19, 20 are formed, the width of which essentially corresponds to a diameter of bearing pins 52, 53 which are fixedly connected to the ski 2 and have a circular cross section. The slot-shaped recesses 50, 51 in the legs 19, 20, in cooperation with the bearing pins 52, 53 fixedly connected to the ski 2, form the joint and guide device 49, which both have a rotational movement between the ski 2 and the support element 3 as well enables a translatory movement of the ski 2 relative to the support element 3 or relative to the legs 19, 20.

The journals 47, 48 are formed at the ends of an anchoring element 54 integrated in the ski body, which is aligned essentially parallel to the tread 27 or to the tread surface 28 and essentially transversely to the longitudinal direction - arrow 26 - of the ski 2 approximately over its entire length Width runs. The further rear bearing journals 52, 53, which are related to the direction of travel, are likewise formed at the ends of an anchoring element 55 of the same type which is integrated in the ski body and is likewise aligned essentially parallel to the running surface 27 or to the running surface covering 28 and likewise essentially transversely to the longitudinal direction. Arrow 26 - of ski 2 runs. The anchoring elements 54, 55 integrated in the ski body and spaced apart in the longitudinal direction - arrow 26 - of the ski 2 form via the bearing pins 47, 48; 52, 53 pivot axes 56, 57, which are aligned essentially parallel to the running surface 27 and transversely to the longitudinal direction - arrow 26 - of the ski 2 and in the two longitudinally - arrow 26 - of the ski 2 spaced-apart 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, as is inevitably the case when driving through undulating terrain or when cornering due to the waist and / or the pretension height of the ski 2. The support element 3 with the coupling parts 4, 5 of the ski binding 6 fastened thereon does not influence the bending stiffness or the flexibility of the ski 2, since the articulated connection 44 and the joint and guide device 49 between the support element 3 and the ski 2 enable the ski to work freely Ski body allowed. The natural flex of the ski 2 is thus retained and the ski binding 6 mounted on the support element 3 has no negative influence on the bending characteristic value provided by the manufacturer of the ski 2 or on the bending stiffness distribution of the sports device 1 which the manufacturer considers the most favorable.

The two pivot axes 56, 57 formed by the anchoring elements 54, 55 run absolutely parallel to one another when projected onto a horizontal plane as well as when projected onto a vertical vertical plane running transversely to the longitudinal direction - arrow 26 - of the ski 2. The anchoring elements 54, 55 integrated in the ski 2 for connecting the ski 2 to the support element 3 are arranged in a plane 58 oriented essentially parallel to the running surface 27 or to the running surface 28 and, under certain conditions, connect several in the longitudinal direction - arrow 26 - to one another Center of gravity 59, 60 spaced apart in relation to several cross-sectional sections of the ski 2 spaced apart from one another. The anchoring elements 54, 55 or the pivot axes 56, 57 are in any case arranged in the neutral fiber or in the neutral layer of the sports device 1 or the ski body, ie, the pivot axes 56, 57 8

AT 410 758 B or the anchoring elements 54, 55 are arranged in those areas in the ski body in which the tensile and compressive stresses which occur in the event of a load or in the event of deflection or deflection cancel each other out and become zero. The neutral fiber or neutral zone of the ski 2 largely untouched by tensile and compressive forces depends in particular on the elasticity modules of the individual layers of the ski 2 and on their thickness and shape or geometry, but normally runs in the region 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 fiber or the neutral zone of the ski 2 is represented by the plane 58 and usually runs parallel to the running surface 27 in approximately half the thickness of the ski 2. This Level 58 connects, especially in the case of a homogeneous, uniform ski body, all the center of gravity 59, 60 of the ski 2 running in the longitudinal direction - arrow 26 - in the individual cross-sectional sections of the ski 2. The pivot axes 56, 57 lie in the plane 58 or in the neutral zone of the ski in particular multilayer ski body and are aligned transversely to the longitudinal direction - arrow 26 - of the ski 2. In the exemplary embodiment shown, the neutral zone or the plane 58 of the ski body runs through the core 8, in particular through the hardwood core of the ski 2. The anchoring elements 54, 55 thus penetrate the core 8 in the transverse direction of the ski 2 and are thereby firmly connected to it held in this under pretension so that displacements between the anchoring elements 54, 55 and the ski 2 are prevented. The anchoring element 54, 55 preferably extends continuously across the entire width of the ski 2 and forms the bearing pins 47, 48; 52, 53 out. The preferably metallic anchoring elements 54, 55 penetrate the core 8, in particular the hardwood core, in this case through holes 61, 62. The core 8, which is essentially rigid and absolutely secure against tearing, is the anchoring elements 54, 55 and the pivot axes 56 formed by them , 57 absolutely tear-proof and high-strength held in the ski 2 or extremely rigid and unrelentingly fixed. The pull-out strength or the absolutely fixed fixation of the anchoring elements 54, 55 in the ski body can be increased by projections 63, 64 projecting like wings. The anchoring elements 54, 55 can be formed by bolt-like elements 65, 66 with a circular cross-section, the plate-like projections 63, 64 projecting radially from the lateral surfaces of the elements 65, 66. The plate-like projections 63, 64 can continuously taper in strength with increasing distance from the central, bolt-like element 65, 66, so that cutting-like longitudinal edges are formed in the regions distanced from the central element 65, 66. The projections 63, 64 thus have an approximately triangular or cutting blade-like cross-sectional shape.

Several projections 63, 64 can also be arranged distributed over the circumference of the bolt-like elements 65, 66. However, two projections 63, 64 are preferably provided for each element 65, 66, the flat sides of which are oriented essentially parallel to the running surface 27 or parallel to the plane 58, so that the relatively high, perpendicular to the plane 58 or essentially perpendicular to the running surface 27 Directed forces can be safely absorbed and a deviation of the central, bolt-shaped elements 65, 66 in the ski body from the intended position is excluded. The projections 63, 64 on the anchoring elements 54, 55 result in a higher contact surface of the same in the ski body, so that a deviation, e.g. a sinking of the same in the ski body or a rotational movement of the same about the pivot axes 56, 57 is avoided. The diameter of the bearing pins 47, 48; arranged at the end regions of the anchoring elements 54, 55; 52, 53 is approximately 4 mm to 14 mm and is preferably made 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 the plane 58 or in the neutral fiber of the sports device 1 or the 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 aligned transversely to the longitudinal direction - arrow 26 - of the ski 2.

The sandwich element 7, which is made up of several layers and which forms the sports device 1 or the ski 2, comprises, in addition to the essentially centrally arranged core layer or next to the core 8, in particular made of wood, further layers at least partially surrounding it. In particular, the sandwich element 7 has an upper flange 67 arranged in the upper edge regions of the ski body and one associated with the tread 27 or the tread covering 28

AT 410 758 B th lower chord 68. At least one upper flange 67 and at least one lower flange 68 are provided near the edge zones of the ski cut, these layers of ski 2 being made of materials of high strength and rigidity. Elastic inserts made of plastic or foam are preferably arranged between the core 8 and the upper and lower chords 67, 68. If necessary, a filler 69, in particular made of plastic or foam, can also be arranged between the core 8 and the load-bearing straps, which has a higher elasticity compared to the core 8 or a lower resistance under pressure loads and can therefore also take on a damping function in the ski body , This composite of the core 8, the upper and lower chords 67, 68 and the filler 69 is surrounded on the one hand by the tread covering 28 and on the other hand by a shell 70 which has a high mechanical strength. If necessary, the supporting straps and the core 8 and the filler 69 can be surrounded by two shells, the outer shell 70 being hard and the inner shell being comparatively soft. As is known per se, the longitudinal edge regions of the shell 70 are supported directly on the running edges 71, 72 which delimit the tread surface 28 and which are preferably made of steel, as a result of which optimal power transmission is achieved.

The sports device 1 is therefore comparable to a rod made of composite material. The position and orientation of the neutral fibers - represented by the plane 58 - is determined by the different elasticity modules of the individual layers and by the cross-sectional geometry of the ski 2. In the exemplary embodiment shown, the individual elasticity modules and geometries of the individual layers of the ski body are designed such that the center of gravity 59, 60 lies in the plane 58 or in the neutral fiber of the ski body. However, it is of course also possible for the center of gravity 59, 60 to lie next to the plane 58 or next to the neutral fibers of the ski body, depending on the individual elasticity modules and geometries of the individual layers or layers of the composite material. Due to the cross-sectional halves of the ski body, which are generally symmetrical to a vertical axis 73, in particular to the z-axis, the center of gravity 59, 60 always lie 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, if the ski 2 is held in the shovel and end area.

4 shows the tension curve of the ski 2 when it is bent about a horizontal axis directed transversely to the longitudinal direction - arrow 26. The stress curve is greatly simplified and shown schematically and represents one of many possible stress curves. This diagram with the stress curve in the individual layers of ski 2 clearly shows the jumps at the individual material limits of the composite material. If the ski 2 bends, i.e. when the ski 2 is loaded perpendicular to the surface 30, the lower flange 68 acts as a tension belt and the upper flange 67 acts as a compression belt, some of the tensile and compressive forces that occur are symbolized in part by arrows 74, 75 for the tensile forces and by arrows 76, 77 for the compressive forces. In the neutral fiber - plane 58 - the oppositely directed tensile and compressive forces cancel each other out and a tension zero line 78, which defines the neutral fibers or plane 58, is formed. The anchoring element 54, 55 for mounting the dimensionally stable support element 3 is arranged precisely at this tension zero line 78 or in the neutral fiber - plane 58. The direction of the arrows 74 to 77 provides information in particular about the tensile or pressure conditions in the ski body and their length provides information about the amount or the magnitude of the forces.

As can be seen above all from FIGS. 2 and 3, the legs 17 to 20 of the support element 3 are inserted into recesses 79 to 82 in the sports device 1 or in the 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 corresponding to the volume of the legs 17 to 20 of the support element 3 to be inserted or inserted therein. Outer surfaces 85 to 88 facing away from one another on the legs 17 to 20 are largely flat with the side surfaces 89, 90 formed by the side cheeks 83, 84, so that a largely stepless transition between the legs 17 to 20 of the support element 3 and the side surfaces 89, 90 is formed on the side cheeks 83, 84. Thus, the width of the sports device 1 is not increased even by attaching the support element 3 and individual projections on the side cheeks 83, 84, which could cause the pair of skis to get caught when skiing, are excluded, since the side surfaces 89, 90 of the side cheeks 83, 84 consistently flat 10

AT 410 758 B or without significant projections. The inclination of the outer surfaces 85 to 88 of the legs 17 to 20 of the support element 3 is adapted to the inclination of the side surfaces 89, 90 on the side cheeks 83, 84 of the ski 2, whereby generally two outer surfaces 85, 86; 87, 88 run diverging from one another and a theoretical line of intersection thereof is formed in the vertical direction above the running surface 27. Inner surfaces 91 to 94 of the legs 17 to 20 are absolutely perpendicular to the pivot axes 56, 57 and lie against inner boundary surfaces 95 to 98 of the recesses 79 to 82 with as little play as possible. In relation to the cross-sectional area of the support element 3, the outer surfaces 85 to 88 and the inner surfaces 91 to 94 of the legs 17 to 20 thus run at an angle to one another, the inner surfaces 91 to 94 being perpendicular to the pivot axes 56, 57 and a theoretical intersection above the upper side 30 the ski 2 is formed.

The recesses 79 to 82 or the corresponding indentations in the ski body, when projected onto a vertical plane pointing in the longitudinal direction - arrow 26 - have lateral boundary surfaces 99 to 102, a theoretical crossing line of the lateral boundary surfaces 99, 100; 101, 102 in relation to a vertical direction lies below the pivot axes 56, 57 or below the anchoring elements 54, 55. The recesses 79 to 82 are thus continuously widening starting from the tread 27 in the direction of the upper side 30, so that with respect to the longitudinal direction - arrow 26 - free spaces between the legs 17 to 20 and the inner boundary surfaces 99 to 102 of the recesses 79 to 82 are formed, which allow relative movements between the ski 2 and the legs 17 to 20 of the support element 20. In order to avoid icing of the free spaces between the legs 17 to 20 and the inner boundary surfaces 99 to 102 of the recesses 79 to 82, they can be filled with an elastic filler 103, e.g. a foam-like filler, which has a certain resilience and is comparatively easy to deform. Likewise, the remaining free spaces between the bearing pins 52, 53 and the recesses 50, 51 in the legs 19, 20 can be filled with an elastic filler 104 in order to prevent ice and snow from being stored.

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

The anchoring elements 54, 55 can either be integrated directly in the manufacture of the sandwich element 7 or inserted between the individual layers, or they can also be fixed in the ski body after the manufacture of the ski 2. For this purpose, the bolt-like anchoring elements 54, 55 must be pressed or driven into the through bores 61, 62 in the ski 2. Especially when the anchoring elements 54, 55 are subsequently inserted into the ski body, they have the radially projecting projections 63, 64, with which the pull-out strength of the anchoring elements 54, 55 is increased, since these projections 63, 64 are surrounded by the material through the through holes 61 , 62 cut and anchor accordingly.

After the anchoring elements 54, 55 are fixed in the ski body, the support element 3 can be attached to the ski 2 in a simple manner. For this purpose, only the two halves of the support element 3 or the support element parts 11, 13 are placed on the bearing pins 47, 48 arranged in the recesses 79 to 82; 52, 53 and to connect the two support element parts 11, 13 via the connecting device 12 to the one-piece support element 3. After activating the connecting device 12, the support element parts 11, 13 or the legs 17 to 20 slide off the bearing pins 47, 48; 52, 53 excluded.

The inner surfaces 91 to 94 of the legs 17 to 20 preferably lie against the comparatively hard, lateral boundary surfaces of the core 8 and / or the upper flange 67 and / or the lower flange 68 with as little play as possible.

5, 6 show a further embodiment of a sports device 1 or ski 2, the same reference numerals being used for parts already described above.

Here, the support element 3 is formed in one piece and in turn is mounted in the recesses 79 to 82 in the ski body via the legs 17 to 20 formed in the corner regions of the plate part 32. The support element 3 is preferably formed by an extruded or continuously cast profile with a U-shaped cross section, on which the central region 16 of the support element 3 is reworked to form the four legs 17 to 20. In particular, the legs protruding from the central plate part 32 are removed in the central region 16 of the profile, so that in FIG

AT 410 758 B

End regions 14, 15, the relatively narrow legs 17 to 20 are formed. The one-piece, one-piece support element 3 is in turn coupled to the ski 2 via the joint connection 44 and via the joint and guide device 49. The anchoring elements 54, 55 of the articulated connection 44 and the articulation and guide device 49, which are firmly connected to the sports device 1 or integrated therein, are formed by hollow cylindrical bearing bushes 105, 106. 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 - of 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 flat with the boundary surfaces 95, 96; 97, 98, so that the recesses 79 to 82 machined into the ski body when the support element 3 is removed are not penetrated by the various bearing parts between the support element 3 and the ski 2 or do not protrude into them. The 4bstand between adjacent legs 17, 18; 19, 20 is again selected such that it is flat and as free from play as possible on the boundary surfaces 95, 96; 97, 98 of the recesses 79 to 82 are present. The bearing bushes 105, 106 which represent the anchoring elements 54, 55 are fixed rigidly and immovably in the ski body. The deviation-resistant positioning of the bearing bushes 105, 106 can in turn be increased by the projections 63, 64 projecting radially from the lateral surface.

To mount 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 is to be inserted into the recesses 79 to 82 and the connection is completed by means of two bearing bolts 107, 108. The cross-sectional shape of the bearing bolts 107, 108 is selected such that they can be inserted into the bearing bushes 105, 106 with as little play as possible. A length of the bearing bolts 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 is chosen to be approximately twice the thickness 109 of the legs 17 to 20, so that the legs 17 to 20 are at least partially penetrated by the bearing bolts 107, 108. The bearing bolts 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 secured by arbitrary means known from the prior art against arbitrary falling out of the bearing bushes 105, 106 after the mounting element 3 has been installed. So it is e.g. possible to glue the bearing bolts 107, 108 in the bearing bushes 105, 106 or to press the bearing bolts 107, 108 into the bearing bushes 105, 106 by means of a corresponding fit and thus 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 are in turn on the neutral fibers - plane 58 - of the ski 2, so that the anchoring elements 54, 55 are largely stress-free embedded. The neutral fiber - plane 58 - in relation to the cross section of the ski 2 again runs approximately in the center area and parallel to the running surface 27.

For absolutely tear-proof fastening of the anchoring elements 54, 55 or the bearing bushes 105, 106, this can be provided in the outer jacket region with projections 63, 64 in the manner of thread turns, so that the bearing bushes 105, 106 in the ski body or in the through bore 61, 62 can be screwed into the ski body and are thus positively connected to the ski 2. Screwing the anchoring elements 54, 55 or the bearing bushes 105, 106 is preferably used on skis 2 with wooden cores. The bearing bushes 105, 106 with the threads arranged on the outer jacket allow, in particular, retrofitting of the anchoring elements 54, 55 in the ski body, namely after the through bores 61, 62 have been machined essentially parallel to the running surface 27 and transversely to the longitudinal direction - arrow 26 - of the ski 2 ,

Through a detachable connection of the bearing bolts 107, 108 to the bearing bushes 105, 106, it is possible in a simple manner to arrange different support elements 3 with different ski bindings 6 quickly and without tools on a specific ski 2 or to carry out a corresponding exchange without problems. 12

AT 410 758 B

FIG. 7 shows another embodiment variant of a sports device 1 or ski 2 with the anchoring elements 54, 55 formed within the ski body for connecting the ski 2 to the support element 3. In the exemplary embodiment shown, the same reference numerals are used for parts already described above, the previous explanations correspondingly valid for the same parts.

The cross-sectional view through the sports device 1 or the ski 2 with the integral support element 3 fixed thereon for holding the ski binding is a sectional view through the bearing points 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 identically integrated in the end region 14 and in the end region 15 of the support element 3 in the ski body. In the following description, only the front anchoring element 54 is referred to

Here, the anchoring element 54 consists of a piston-cylinder arrangement, at least one cylinder 110 having two pistons 111, 112 guided therein. The cylinder 110 is designed in particular as a hollow cylinder 113 or as a sliding bush 114 for the pistons 111, 112. The cylindrical pistons 111, 112 are aligned in the sliding bush 114 in such a way that their longitudinal central axes 115, 116 form the pivot axis 56 and lie in the neutral fibers - plane 58 - of the ski body. The two pistons 111, 112 are axially adjustable relative to one another with respect to their longitudinal central axes 115, 116 in the sliding bush 114, i.e. the pistons 111, 112 are guided by the sliding bush 114 in such a way that they can be moved towards and away from one another in the direction of their longitudinal central axes 115, 116, but are held as immovably as possible in the other spatial directions.

At least the end regions of the two pistons 111, 112 which face away from one another have a circular cross section and form the bearing journals 47, 48 for the support element 3. The pistons 111, 112 preferably have a circular outline throughout, based on their cross section. Of course, however, it is also possible to cross-section the facing end regions, i.e. the regions following the journal 47, 48, e.g. to be rectangular and accordingly to provide rectangular guide bores 117, 118 in the sliding bush 114.

The mutually facing end regions of the bolt-like pistons 111, 112 guided in the sliding bush 114 preferably have heads 119, 120 which prevent the pistons 111, 112 from falling out of the sliding bush 114. A cross-sectional dimension of the heads 119, 120 at the mutually facing ends of the pistons 111, 112 is chosen to be larger than a diameter of the bearing pins 47, 48 in the end regions distant therefrom. A corresponding guide recess 121 is assigned to the heads 119, 120 in the central region of the sliding bush 114, an extension 122, 123 being formed in each case at the transition from the guide recess 121 into the two guide bores 117, 118, which detects 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 forced under the action of a spring-elastic pretensioning device 124, in particular a compression spring 125, in the initial or rest state of the anchoring element 54 into their greatest possible distance from one another. The elastic pretensioning device 124 thus causes the two pistons 111, 112 to be displaced into the most distant position, in which case the bearing pins 47, 48 protrude from end regions 126, 127 of the sliding bush 114 or the bearing pins 47, 48 the end regions 126, 127 overtop.

In particular, the anchoring element 54 in this case forms a releasable connecting 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. This connection device 128, which can only be operated manually, is designed in the manner of a preferably lockable snap lock, which enables an immediate and largely automatic connection of the ski binding to the ski 2 and a corresponding disassembly thereof.

The slide bush 114 is preferably formed in two parts, the parting plane preferably being formed in the central region or in the region of the central guide recess 121 in order to be able to insert the two pistons 111, 112 with the heads 119, 120 into the parts of the slide bush and between the pretensioning device 124 between them to be able to attach the two heads 119, 120. The two parts of the sliding bush 114 are then connected via a connecting device, e.g. over a 13th

AT 410 758 B

Thread arrangement 129, assembled to form a one-piece sliding bush 114. Of course, it is also possible to connect 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 sliding bush parts.

The anchoring element 54, comprising the pistons 111, 112, the sliding bush 114 and the spring-elastic pretensioning device 124, is integrated in the ski body in such a way that it cannot be pulled out, the end regions 126, 127 of which at least a partial area of the boundary surfaces 95, 96 of the recesses 79, 80 or indentations in the ski body for insertion the legs 17, 18 of the support element 3 form. The anchoring element 54 is embedded between the individual layers of the ski 2, in particular it 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 deviation-resistant mounting of the anchoring element 54 in the ski body can optionally be increased by the projections 63, 64 designed in accordance with the preceding descriptions or figures. Such an embedding of the anchoring element 54 in the ski body preferably takes place directly during the manufacture of the sports device 1 or the ski 2.

In addition, it is also possible to provide a threaded arrangement 130 on the outer jacket of the anchoring element 54. This thread arrangement 130 has a relatively large pitch and relatively high thread flanks in order to be able to subsequently insert the anchoring element 54 into an already manufactured ski 2. In this case, a through hole 61 connecting them is provided between mutually opposite recesses 79, 80, into which the anchoring element 54 with the threaded arrangement 130 can be screwed in in a simple manner and is thereby anchored in the ski body in a manner which prevents it from being torn out.

To connect the support element 3 to the ski 2 via the anchoring element 54, the recesses 45, 46 are arranged in the legs 17, 18 with a cross section corresponding to the bearing journal 47, 48. These recesses 45, 46 can be formed as a blind hole or as a through hole in the legs 17, 18. To mount the support element 3 on the ski 2, only the pistons 111, 112 have to be inserted into the slide bush 114 against the action of the elastic pretensioning device 124, so that the bearing pins 47, 48 are at least flat with the end regions 126, 127 of the slide bush 114. Thereupon, the support element 3 with the legs 17, 18 can be inserted into the recesses 79, 80, and if the guide bores 117, 118 overlap or are aligned with the recesses 45, 46, the pistons 111, 112 are in particular by the elastic pretensioning device 124 by the compression spring 125, moved apart so that the bearing bolts 47, 48 engage in the recesses 45, 46 and produce the articulated connection 44 and also the articulation and guide device 49 in the rear end region of the support element 3.

The support element 3 can be coupled to the ski 2 in a simple manner by means of such anchoring element 54 and is connected to the ski in a high-strength manner. For the automatic or tool-free coupling of the support element 3 to the ski 2, link paths 131, 132 can be provided on the legs 17, 18, which enable an unimpeded, automatic snapping of the support element 3 onto the ski 2. These slide tracks 131, 132 are formed by chamfered planes on the legs 17, 18, the pistons 111, 112 automatically into the slide bush 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 2 114 drive and then overlap with the recesses 45, 46 protrude 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 the support element 3 with the ski binding to be mounted on the ski 2 without tools, and thus any support elements 3 with any ski bindings can be clicked in on a specific ski 2 in a simple manner or to be clipped on. For a possible disassembly of the support element 3 from the ski 2, the recesses 46 can be provided as through-bores through which the pistons 111, 112 or the bearing pins 47, 48 are pushed out of engagement with the legs 17, 18 of the support element 3 by pushing them back into the sliding bushing 114 can be brought. The support element 3 can thus be decoupled at 14

AT 410 758 B

Required at any time by pushing the pistons 111, 112 or the bearing journals 47, 48 into the sliding bush 114 using suitable means. The recesses 45, 46 for mounting the support element 3 on the ski 2 are then preferably selectively closable with a stopper 133 in order to prevent the ingress of ice or snow.

In addition, it is also possible to design the pistons 111, 112 without the heads 119, 120 if the recesses 45, 46 in the legs 17, 18 are designed as blind holes through which the extension movement of the pistons 111, 112 from the sliding bush 114 is limited. In particular, with such a design it is also possible to limit the pistons 111, 112 in the extension movement from the sliding bushing 114 via plugs 133 which can be screwed into the recesses 45, 46 from the outside. 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 engage in the recesses 45, 46 and on the other hand are also guided in the sliding bush 114. By removing the plugs 133 from the legs 17, 18, at least one piston 111, 112 can then be removed, and thereby the support element 3 can also be detached from the ski 2.

Furthermore, it is possible to design the anchoring elements 54, 55 as bearing bushes 105, 106 integrated in the ski body - as can be seen in particular from FIG. 6 - which preferably have recesses 79, 80; 81, 82 via their inner guide hole, which is designed to receive and hold a preferably continuous bearing pin 107, 108 or also to accommodate two pistons 111, 112. The support element 3 is then placed on the sports device 1 such that the recesses 45, 46; 50, 51 are aligned with the inner bearing bores of the bearing bushes 105, 106, whereupon the bearing bolts 107, 108 can be inserted and connect the support element 3 to the ski 2 in an articulated manner. At least one of the recesses 45, 46; 50, 51 can be designed as a blind hole-like recess that limits at least one axial displacement movement of the bearing bolts 107, 108. After the bearing bolt 107, 108 has been inserted, the recess 46; 51 can be closed with the plug 133 or the plug 133 can be inserted into the recess 46; 51 are screwed in, so that falling out of the bearing pin 107, 108 is excluded. Preferably, by screwing in or inserting the plug 133, the bearing pin 107, 108 is fixed largely immovably in the axial direction.

Regardless of the design shown, it is of course also possible to assign the pistons 111, 112 to the legs 17, 18 and to make them extendable and retractable from them, and therefore the bearing journals 47, 48, which can be extended and retracted from the legs 17, 18, of a corresponding one Assign slide bushing 114, which is integrated in the ski body and can optionally also be formed as a blind hole-like recess. Such a training would represent an equivalent training to the previously described embodiment.

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

8 and 9 show a further embodiment variant of a sports device 1 or a support element 3 connected to the ski 2, which supports the ski binding 6. Here, the same reference numerals are used for parts already described above, and previous descriptions are analogously applicable to the same parts with the same reference numerals.

Here, the support element 3 is substantially U-shaped in cross-section over its entire longitudinal extent, that is, the leg plates projecting from the central plate part 32 essentially at right angles extend continuously over the entire length of the support surface 21 for the ski binding 6 or for plate part 32 forming the foot of the user. Legs 17, 18; projecting on both sides of plate part 32; 19, 20 thus also extend over the central region 16 of the supporting element 3. In the mounting region of the supporting element 3 on 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 such that the outer surfaces 85, 86; 87, 88 terminate essentially steplessly or flush with the side surfaces 89, 90 of the side cheeks 83, 84. Front ends 134, 135 of support element 3 close 15

AT 410 758 B preferably forms an acute angle with the support surface 21, that is, the end surface regions of the support element 3 in the end regions 14, 15 extend, starting from the running surface 27, towards the support surface 21, and are conically widening in a side view - according to FIG 8 - V-shaped boundary edges of the legs 17, 18; 19, 20 in relation to the longitudinal direction - arrow 26 - of the ski 2 is formed. The recesses 79, 80; 81, 82 in the longitudinal side areas of the ski 2 are chosen larger than the surface dimensions of the continuous legs 17, 18; 19, 20, so that between the boundary edges of the legs 17, 18; 19, 20 and the boundary edges of the recesses 79, 80; 81, 82 a free space is formed, which allows a largely unhindered deformation of the ski 2 relative to the support element 3. Thus, in particular between the front ends 134, 135 and the boundary surfaces 99, 100 and also between the running surface 27 facing longitudinal edges 136, 137 of the legs 17, 18; 19, 20 and the lower boundary surface of the recesses 79, 80; 81, 82 free spaces 138, 139 are formed which, when the ski 2 is deformed, permit a largely free mobility with respect to the rigid support element 3 and therefore in particular represent a compensating margin.

Of course, it is also possible to fill the free spaces 138, 139 with a filler which has a comparatively easy deformability and prevents ice and snow from becoming stuck in the free spaces 138, 139. Transversely to the longitudinal direction - arrow 26 - of the ski 2, the support element 3 is largely immovable relative to the ski 2. This can be achieved, in particular, by the inner surfaces 91 to 94 resting against the boundary surfaces 95 to 98 of the recesses 79 to 82 with substantially no play.

The support element 3 with the ski binding 6 is supported on the ski 2 via the anchoring elements 54, 55 integrated in the ski body, or is connected to the ski 2 via these. 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 mounting area for the ski binding 6, so that the bearing pins 47, 48; 52, 53 into the recesses 79, 80; 81, 82 protrude or protrude beyond the boundary surfaces 95 to 98 of the recesses 79 to 82. The bearing pin 47, 48; 52, 53 are corresponding recesses 45, 46; 50, 51 assigned in the legs 17 to 20. The recesses 45, 46; 50, 51 are worked into the leg plates in a slot-like manner starting from the boundary edges of the legs 17 to 20. Longitudinal central axes 140, 141 of the slots 45, 46; 50, 51 run essentially at right angles to one another when viewing a side region of the support element 3. For example, the longitudinal central axis 140 of the recesses 45, 46 is essentially parallel to the running surface 27, whereas the longitudinal central axis 141 of the further slot-shaped recesses 50, 51 is oriented essentially perpendicular to the running surface 27 or perpendicular to the support surface 21. The dimensions of the slot-shaped recesses 45, 46 are selected such that the support element 3 is guided on the ski 2 with as little play as possible in the vertical direction via the bolt-shaped element 65, but in the longitudinal direction - arrow 26 - of the ski 2 is relatively displaceable. The dimensions of the further slot-shaped recesses 50, 51 in the end region 15 are selected such that the support element 3 is fixed immovably in relation to the longitudinal direction - arrow 26 - of the ski 2. The support element 3 is supported via the recesses 45, 46; 50, 51 with respect to a vertical direction each rigidly on the journal 47, 48; 52, 53 from.

The slot-shaped recesses 45, 46; 50, 51 are preferably machined into the legs 17 to 20 of the substantially U-shaped profile by means of a separate machining operation, the recesses 45, 46 being machined from the front end 134 of the support element 3 in the longitudinal direction of the support element 3 into the legs 17, 18 or milled. The slot-shaped recesses 50, 51 in the end region 15 of the support element 3 are machined or milled into the legs 19, 20 perpendicular to the support surface 21, starting from the longitudinal edges 136, 137.

Due to the previously described design of the support element 3 and the recesses 45, 46; 50, 51 this is done in a simple manner via the journals 47, 48; 52, 53 mountable on ski 2. For mounting the support element 3 with the ski binding 6 on the ski 16

AT 410 758 B 2, the end area 14 is to be put into operative connection with the ski 2 and subsequently the end area 15 is to be put into work connection with the bolt-shaped element 66. For this purpose, only the journals 47, 48 are to be introduced into the recesses 45, 46 and subsequently the recesses 50, 51 are brought into engagement with the journals 52, 53 or the end region 15 is placed on the bearing journals 52, 53.

For secure connection of the support element 3 to the ski 2, at least one recess 50, 51 is assigned a locking element 142 which can be operated by the user of the sports device 1 and which optionally blocks an opening 143 of the recesses 50, 51. When the blocking element 142 is deactivated, the opening 143 of the recesses 50, 51 is released, as a result of which the bearing pins 52, 53 can be inserted into the recesses 50, 51 or removed therefrom. The blocking element 142 can subsequently be activated by the user of the sports device 1, as a result of which the opening 143 is closed and a separation of the support element 3 from the bearing pins 52, 53 is prevented. When the locking member 142 is activated, the end region 15 of the support element 3 is connected in an articulated manner to the sports device 2, translatory movements between the end region 15 of the support element 3 and the ski 2 being largely prevented.

In the exemplary embodiment shown, the locking member 142 is formed by a locking bolt 144 which can be displaced in the longitudinal direction - according to arrow 26. The locking bolt 144, which can be displaced by the user of the sports device 1 via a handle 145, can be displaced in a guide bore 146 in at least one leg 19, 20 of the support element 3 in the longitudinal direction of the support element 3. The locking bolt 144 of the locking member 142 is preferably pushed via a spring-elastic pretensioning device 147 into that end position in which lifting of the support element 3 from the ski 2 is prevented. This spring-elastic pretensioning device 147, which is preferably formed by a compression spring 148, is used to hold the locking bolt 144 in the rest or normal state in the end position in which the opening 143 of the slot-shaped recess 50, 51 is closed. When the locking bolt 144 is moved by means of the handle 145 counter to the force of the pretensioning device 147, the end region of the locking bolt 144 facing away from the compression spring 148 is removed from the recess 50, 51, as a result of which the opening 43 of the recess 50, 51 is completely released and the support element 3 can be lifted off the trunnions 52, 53. Thereupon, the bearing devices 22, 23 in the front end region 14 of the support element 3 can also be removed and the support element together with the ski binding 6 can be removed from the ski 2.

A possible displacement path of the locking bolt 144 is selected to be at least the same size as a protrusion of the locking bolt 144 from the guide bore 146 receiving the compression spring 148 in relation to the locked position of the locking member 142. The longitudinal axis of the guide bore 146 is essentially perpendicular to the longitudinal central axis 141 of the recess 50, 51 ,

The guide bore 146 is preferably machined from the end 135 in the longitudinal direction of the support element 3 in the legs 19, 20 and crosses the slot-shaped recess 50, 51. The locking bolt 144 is against the handle 145, which can preferably be screwed to the locking bolt 144, against Falling out of the guide bore 146, which runs essentially parallel to the running surface 27, the handle 145 protrudes radially from the locking bolt 144 and the displacement path of the locking bolt 144 is fixed for the handle 145 via a slot-like guide track 149. 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 of the guideway 149 for the handle 145, a branch, perpendicular to the displacement path of the locking bolt 144, can be provided in the guideway 149, as indicated schematically , which allows the locking bolt 144 to be fixed at the respective position of the branch by reaching behind with the handle 145. In particular, by radially rotating the locking bolt 144 at the respective positions at which such a locking lug or branch is formed in the guideway 149, it is possible to hook the handle 145 with this locking lug, as a result of which the locking bolt 144 is held in the respective position. When the handle 145 is pivoted back into the guideway 149 again, the locking bolt 144 is automatically pushed into the locking position via the pretensioning device 147. In this locking position of the locking bolt 144, a locking lug or a branch can also be provided in the guideway 149, which prevents the locking bolt 144 from being automatically displaced against the spring force into the release position of the locking member 142. The combined, 17th

AT 410 758 B translational and rotary movement of the locking bolt 144 via the handle 145, which is predefined via the guideway 149, can be realized with or without the action of a pretensioning device 147.

The adjustment movements of the locking member 142 are similar to the adjustment movements of the breech of firearms.

The preceding description thus 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 activated and deactivated in a very short time by any user or layperson, and thereby the usual , to be carried out by experts to assemble the binding via screw connections.

The two anchoring elements 54, 55 are in turn each arranged in the neutral zone or in the neutral layer - plane 58 - of the ski body, which is formed in the ski body when the bending stresses are directed perpendicular to the running surface 27. The anchoring elements 54, 55 can in turn be provided with projections 63, 64 for highly rigid fixing in the ski body, which extend essentially parallel to the running surface 27.

The support element 3 is preferably formed from an extruded profile made of aluminum, aluminum alloys, plastics or fiber-reinforced plastics with high flexural strength and torsional rigidity. A locking member 142 is preferably assigned to each side cheek 83, 84 of the ski 2, which connects the support element 3 on each longitudinal side to the bearing pins 52, 53 so that it cannot be lifted off and thereby increases the torsional rigidity of the support element 3 or of the entire sports device 1.

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 can be limited directly by the material of the hard outer shell 70, i.e. the recesses 79 to 82 in the ski body are already formed during the manufacture of the ski 2 by a one-piece shell 70 with corresponding indentations in the mounting area for the support element 3, whereby a ski structure is uniformly covered by the shell 70, which prevents liquids from penetrating into the Avoids chikers reliably.

Of course, it is also possible to achieve optimal water tightness for recesses 79 to 82 machined into the ski body after the manufacture of the ski 2 by providing their surfaces with a waterproof and / or elastic coating, such as e.g. Varnish to be coated later.

10 shows another embodiment variant of an anchoring element 54, which is designed for the subsequent fixing of the same in the ski body and e.g. serves to hold a support element according to FIG. 8 on a ski. This bolt-shaped element 65 has in the central area on its outer circumference the threaded arrangement 129 and in the end areas related to its longitudinal direction a bearing journal 47, 48 is formed with a circular cross-section. In the front ends of the bolt-shaped element 65, blind-hole-like latching elements 150 with a polygonal cross-section can be formed, via which the bolt-shaped element 65 can be connected to a corresponding tool and can be set in rotation, the latching element 150 being able to absorb a relatively high mechanical torque. The locking element 150 can e.g. have a square or hexagonal cross-section and the tool can e.g. be formed by an Allen key, via which corresponding torque can be transmitted to the bolt-shaped element 65. The bolt-shaped element 65 can thus be coupled with a corresponding tool via this latching element 150 and screwed into a correspondingly prepared through hole in the ski body via the thread arrangement 129. The through hole extends from one side cheek of the ski to the opposite side cheek and runs essentially parallel to the tread and transversely to the longitudinal direction of the ski. A diameter of this through hole is selected such that the threaded arrangement 129 of the bolt-shaped element 65 engages in the ski body and, after screwing, holds it in the ski body so that it cannot be pulled out.

FIG. 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, a further embodiment of the locking member 142 on the connection device 128 to prevent the support element 3 from being detached arbitrarily from the ski 2 shown. 18

AT 410 758 B

Here, the locking member 142 comprises a pawl 151 which is pivotally mounted about an axis 152 which runs parallel to the pivot axis 57 of the bearing pin 52. In the locking division of the locking device, the locking pawl 151 engages behind the surface area of the bearing pin 52 assigned to the opening 143 of the recess 45. This pivotally mounted locking pawl 151 is preferably in the normal state via the pretensioning device 147, which is preferably formed by a compression spring 148 pushed the locking division, in which the bearing pin 52 is engaged by the detent 153 of the pawl 151 and thereby fixes the support element 3 relative to the bearing pin 52, but allows rotary movements around the bearing pin 52 or about the pivot axis 57. The pawl 151 is preferably provided with the handle 145, which enables a comfortable pivoting of the pawl 151 against the action of the pretensioning device 147 about the axis 152, the locking lug 153 then being moved out of the region of the recess 50 and thus the support element 3 from the ski 2 releases.

The angle enclosed by the locking lug 153 between its boundary edges is preferably less than 90 ° or the locking lug 153 is formed at an acute angle, so that when the pawl 151 hits the bearing journal 52, it is automatically pivoted counterclockwise, for example, and after the bearing journal has been fully inserted 52 the pawl 151 automatically springs back into the recess 50 and thus the locking member 142 is automatically set into the locked state. The formation of such a pivotable pawl 151 with an acute-angled locking lug 153 which engages behind the bearing journal 52 in the locked state thus enables the support element 3 to be fully automatically locked onto the ski 2, 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 on the ski 2 can of course also be used in all the exemplary embodiments described above.

In the locked state of the locking member 142, a locking edge 154 of the locking lug 153 engaging behind the bearing pin 52 extends essentially at right angles to the longitudinal central axis 141 of the slot-shaped recess 50 and thus blocks the opening 143 thereof.

If necessary, the handle 145 or the pivotable pawl 151 can also be assigned locking means which preclude unintentional pivoting of the pawl when the sports device 1 is in operation.

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

12 and 13 show an exemplary embodiment of the ski 2 according to the invention or of the sports device 1 according to the invention, the same reference numerals being used for parts already described above.

Here, the support element 3 is also made of several parts, in particular of two parts, the separating and / or joining area 35 running transversely to the longitudinal direction - arrow 26 - of the ski 2 or of the support element 3 approximately in the central area 16 thereof. The support element parts 11, 13 thus formed are in turn positively connected to one another in the separating and / or joining area 35 via a connecting device 12, in particular via a telescopic guide arrangement 155, and thus form 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 and apart. In the other spatial directions, the two support element parts 11, 13 are fixed immovably to one another via the guide arrangement 155. The guide arrangement 155 formed in the illustrated embodiment in the central region 16 of the support element 3 between the two support element parts 11, 13 can be formed by any guide designs between two profile parts known from the prior art. For example, the support element part 11 can be designed such that it at least partially encompasses the support element part 13 on the outside and thus the support element part 13 can be pushed into and out of the support element part 11. Furthermore, as shown schematically, the support element part 13 can have a guide extension 156 with a circular or polygonal cross section at the end area facing the support element part 11, which can be inserted into a corresponding guide recess 157 in the second support element part 11 with a corresponding cross section. In the two end regions 14, 15 of the 19th, related to the longitudinal direction - arrow 26 - of the ski 2

AT 410 758 B

Support element 3, the coupling parts 4, 5 of the ski binding 6 are each mounted in a longitudinal guide device 158, 159.

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 is on the support element part via the longitudinal guide device 158 11 stored and optionally adjustable in the longitudinal direction - arrow 26 - relative to this. Analogously to this, the coupling part 5 is mounted on the support element part 13 via the longitudinal guide device 159 and is adjustable relative to the support element part 13 in the longitudinal direction - according to arrow 26 - guided by the longitudinal guide device 159. The longitudinal guide devices 158, 159 thus allow the coupling parts 4, 5 to be adjusted in the longitudinal direction - according to arrow 26. In the other spatial directions, the coupling parts 4, 5 are largely immovably fixed.

The coupling part 4, which is designed in particular as a toe of a safety ski binding, is connected via a connecting member 160 to the coupling part 5 which is designed in particular as an automatic heel unit of a safety ski binding. The connecting member 160 connecting the two coupling parts 4, 5 can be formed, for example, by a connecting rod or a connecting band in a rigid or flexible design. However, the connecting element 160 is in particular designed to be strain-resistant, so that the coupling parts 4, 5 which are connected to one another via the connecting element 160 are held at the distance from one another determined by the connecting element 160. Optionally, the connecting member 160 can be made length-adjustable via an adjusting and / or locking device 161 in order to be able to change the distance between the coupling parts 4, 5 and thus to be able to adapt the ski binding 6 to different shoe sizes in a simple manner.

At least one coupling part 4 or 5 can be fixed immovably via the adjusting and / or locking device 161 relative to the respective support element part 11 or 13. In the exemplary embodiment shown, the coupling part 4 or the front jaws is optionally fixed with the support element part 11 in its relative position to the support element part 11 via the adjusting and / or locking device 161. The adjusting and / or locking device 161 has an actuating element 162, by means of which the coupling part 4 can be fixed in relative positions to the support element part 11 in relation to the longitudinal direction - arrow 26 - so that it is fixed immovably at the respectively desired position when the locking device is activated. The coupling part 5 is connected in motion to the coupling part 4 via the connecting element 160 and remains freely sliding in the longitudinal guide device 159. The user of the sports device 1 can therefore use the adjusting and / or locking device 161 to determine the relative position of the entire ski binding 6 relative to the ski 2 or change to the support element 3, the distance between the two coupling parts 4, 5 corresponding to the shoe size remaining unchanged by the expansion-resistant connecting member 160. The actuating member 162 interacts with a locking pin or the like, which, when the actuating member 162 is adjusted, optionally connects the coupling part 4 to the support element 3 or to its longitudinal guide device 158 in a motionless manner.

The support element part 11 comprises the legs 17, 18 directed from the support surface 21 in the direction of the underlying ski 2, which are spaced from one another at a distance corresponding to the width of the ski 2. The end regions of the legs 17, 18 facing the ski 2 are articulated to the ski 2 via the bearing devices 22, 23. The articulated connection 44 in the end region 14 of the support element part 11 with the ski 2 comprises, in the exemplary embodiment shown, connecting elements 163 which are formed in particular by a pair of fastening screws 164, 165 which can be screwed into the anchoring element 54 or 55 integrated into the ski body.

The anchoring element 54, 55 extends continuously between the two side surfaces 89, 90 of the side cheeks 83, 84 of the ski 2. 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 full area on the side cheeks 83, 84 and on the end faces of the anchoring element 54, 55. To produce the articulated connection 44 between the supporting element part 11 and the ski 2, the connecting elements 163, in particular the fastening screws 164, 165, each pass through one leg 17, 18 via the recesses 45, 46 and are movable 20 with the end regions of the anchoring element 54, 55

AT 410 758 B rigidly and tear-proof connected. The fastening screws 164, 165, which are screwed or screwed in over the side cheeks 83, 84 of the ski 2 transversely to the longitudinal direction - arrow 26 - and essentially parallel to the running surface 27 into the two anchoring elements 54, 55 spaced apart in the longitudinal direction - arrow 26 - form the journals 47, 48 for the articulated mounting of the support element part 11. The fastening screws 164, 165 are secured against rotation after the fastening of the support element part 11 and, as stated, form the bearing pins 47, 48 in a shaft part facing the screw head. The shaft part of the fastening screws 164, 165 preferably has a larger diameter than the threaded section of the fastening screws 164, 165 facing away from the screw head. The screw heads of the fastening screws 164, 165, in cooperation with the threads, allow the legs 17, 18 to fit snugly on the side faces 89, 90 of the ski 2 and prevent the legs 17, 18 from sliding off the bearing pins 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 likewise form a pair of legs ajs, each of which extends to the underlying ski 2 and when attached Support element 3 bear directly against the side cheeks 83, 84. The anchoring elements 54, 55 assigned to the pair of legs and integrated in the ski 2 each lie in the neutral zone or in the neutral layer - plane 58 - of the ski 2 if the latter is subjected to bending stresses directed perpendicular to the running surface 27.

Furthermore, the anchoring elements 54, 55 are arranged on a common anchoring layer 166 integrated in the sandwich element 7. This plate-shaped anchoring layer 166, which receives or connects the anchoring elements 54, 55, is oriented with its two large flat sides essentially parallel to the running surface 27. A longitudinal extension of the anchoring 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 plane 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 ski 2, which is considered to be a composite material, and is oriented essentially parallel to the tread 27 of the ski 2, provided that this is subjected to bending stresses directed perpendicular to the tread 27.

A difference to the previously described exemplary embodiments is that the two pairs of legs or respectively the legs 17, 18 and the legs 19, 20 in the two distal end regions 14, 15 each have an articulated connection 44 on the side cheeks 83, 84 are connected to the ski 2 in an articulated manner and the longitudinal compensation device required for free shapability of the ski 2 is formed directly on the support element 3, in that it comprises at least two support element parts 11, 13, which can be moved relative to one another via a guide arrangement 155 directed in the longitudinal direction - arrow 26 , The guide arrangement 155 acting in the longitudinal direction - arrow 26 - is thus realized via at least two support element parts 11, 13, the two support element parts 11, 13 each being articulated with the ski 2 via an articulated connection 44 each with a transverse to the longitudinal direction - arrow 26 - and in pivot axes 56, 57 aligned substantially parallel to the running surface 27 are connected to the ski 2.

Instead of arranging the guide arrangement 155 in the central region 16 of the support element 3, it is also possible to arrange both coupling parts 4, 5 of the ski binding 6 on only one support element part 11 and thus the guide arrangement 155 e.g. To be provided in the end region 15 of the support element 3. In this case, the connecting member 160 can then be omitted and the two coupling parts 4, 5 can be held directly on the one supporting element part 11 or carried by the latter. The longitudinal compensation via the guide arrangement 155 can then be made by the relative displacement of the support element part 13 relative to the support element part 11, e.g. in the rear end region 15 of the support element part 13. If necessary, it is also possible to reinforce the bearing devices 22 to 25 via support cams 167 to 170. These support cams 167 to 170 protrude from the inner surfaces 91 to 94 of the legs 17 to 20 or from the underside 31 of the support element 3 and result in a linear support surface on the upper side 30 of the ski 2. An additional support cam 167 to 170 is therefore provided Support of the support element part 13 on the 21st

Claims (41)

AT 410 758 B top 30 or on the upper cover layer or shell 70 of the ski 2. The line-shaped contact surfaces between the ski 2 and the support cams 167 to 170 arranged on the support element 3 are achieved by supporting bodies with an arcuate outer surface, the surface of the ski 2 or the top layer of the ski 2 extending tangentially to the outer surfaces of these support cams 167 to 170. The contact surface is arranged essentially vertically above the pivot axes 56, 57. 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 ski 2, since these transmit the force effect directly via the legs of the shell 70 to the running edges 71, 72. Impairments of the articulated connection 44 between the support element 3 and the ski 2 are negligible with appropriate dimensioning or with correspondingly soft support cams 167 to 170, but nevertheless result in a stabilization of the connecting device between the support element 3 and the ski 2 and an undelayed introduction of force into the Ski 2 and vice versa. The anchoring elements 54, 55 have a cross-section, i.e. viewed transversely to the longitudinal direction - arrow 26 - of the ski 2, a polygonal, e.g. square cross-section, but can also take circular or any other cross-sectional shapes. The anchoring elements 54, 55 can in turn be integrated in the core 8 of the ski 2, which can be made of wood or other core building materials, or the anchoring layer 166 receiving the anchoring elements 54, 55 is fixed in the ski. If appropriate, the plate-shaped anchoring layer 166 passes through the block-like anchoring elements 54, 55 via slot-shaped openings with a corresponding cross-section arranged in them, so that the distance between the two anchoring elements 54, 55 from one another is adjusted to different lengths of support elements 3 by merely moving them on the reinforcing layer 166 before they are embedded can be. In summary, it can be stated that the support element 3 for the ski binding 6 is supported in each of its end regions 14, 15 on the anchoring elements 54, 55 or anchoring layers 166 integrated in the ski body and arranged in the neutral zone - plane 58 - of the same this is connected. Furthermore, the support element 3 for receiving a plurality of coupling parts 4, 5 of the ski binding 6 is fastened in the decentralized, approximately corresponding to the length of the shoe, distanced regions with the ski 2 on its side cheeks 83, 84. For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the sports device 1, this or its components have been partially shown to scale and / or enlarged and / or reduced.
