The distribution device of the prior art sports equipment has a carrier on which a ski binding or the like coupling device for receiving the user is provided. The carrier is connected via a joint arrangement of the distribution device with the sports equipment, which joint arrangement has two, longitudinally spaced from each other in the longitudinal direction pivot arms pivotally connected via a respective joint at one arm end with the sports device and at the other end of the arm with the carrier are. In this case, the carrier is supported relative to the ski board of the ski by a torsion bar arranged approximately centrally between the pivot arms in such a way that the carrier is supported by a starting position against the restoring force of the rotating shaft. bar spring in a sports device approximate compensation position is movable. In order to improve the guiding properties and directional stability even with short turns and the drift in oblique driving on steeper slopes, the support arms at its front and rear end pivoting arms, which are guided in arranged on the ski surface bearing elements connected to the ski, in that, by rotating the pivoting arms about their axes of articulation, the carrier describes superimposed vertical and horizontal movement towards the ski surface, wherein the carrier is resiliently supported against the ski at least at one location between the articulated connections of the front and rear ends by means of the torsion bar spring. However, the distribution device of the prior art sports equipment is multipart, connected to a considerable additional weight and builds up, which can abolish the advantages of this distribution device for the user.

It is therefore an object to provide a sports equipment of the type mentioned with at least one distribution device that can significantly improve the ride comfort and possibly also the leadership characteristics of the sports equipment for the user.

The achievement of this object is in the sports equipment of the type mentioned in particular that the at least one restoring element is an elastically deformable spring or damping element, which is held on the one hand on the carrier and on the other hand on sports equipment. The sports device according to the invention, which can be designed, for example, as a ski or as a roller carrier, has at least one distribution device for the forces and loads to be transmitted to the sports device. This at least a distribution device connects the sports equipment with a carrier carrying a ski binding or the like coupling device for receiving the user. In this case, the carrier is connected via a joint arrangement with the sports equipment, which has at least one pivot arm, which is pivotally connected via a respective joint at one arm end with the sports equipment and at the other end of the arm: with the carrier. By pivoting the pivot arm of the carrier is movable from a starting position against the restoring force of at least one elastic return element in a sports device approximate compensation position. As a restoring element, an elastically deformable spring or damping element is provided which is held on the one hand on the carrier and on the other hand on the sports equipment. This at least one spring or damping element may be so clamped or held between the carrier and the sports device that a stable and track safe Verbin ^¬ connection between the carrier and the sports device itself is then ensured ^¬ achieved if the at least one distribution device, only one or two Swing arms has. At the same time, however, such a spring or damping element also has sufficient elasticity in order to only damply transmit the shocks and vibrations acting on the sports device to the wearer and the user held on the wearer. This at best only subdued transmission of shocks and vibrations is perceived by the user as significantly increased ride comfort.

It provides a particularly simple and producible with little effort embodiment according to the invention that the at least one spring element is designed as an elastically deformable tube. Such an elastically deformable tube can unfold the desired spring and damping properties due to its shape and the inherent elasticity of the material used. It may be advantageous if the at least one serving as a spring element tube is oriented with its longitudinal axis tube transverse to the longitudinal extent of the sports equipment.

A preferred embodiment according to the invention, which is characterized by particularly good spring and damping properties on the one hand and by stable leadership properties on the other hand, provides that the at least one spring element is designed as a resilient flexible spring plate.

The spring-elastic flexible spring plate can be made of any suitable spring-elastic material. An advantageous embodiment according to the invention provides that the spring plate is made of carbon. A preferred embodiment of the invention, however, is that the at least one spring plate is designed as a spring steel plate.

In order to design the at least one spring plate on the one hand with sufficient rigidity and stability and on the other hand with a satisfactory spring elasticity, an advantageous development according to the invention provides that the spring plate is defined by at least one edge-side indentation or molding and / or at least one plate opening Flexibility has.

In order to be able to connect the distribution device provided between the carrier and the sports device securely and firmly to the sports device, the at least one distribution device has a holder held on the sports device, which is connected to the at least one pivot arm via the at least one joint.

To make the spring-elastic bending between the carrier and the holder _:. it is expedient if at least one holding slot is provided on the carrier and on the holder of the at least one distribution device, in which holding slots the at least one spring plate is inserted with its adjacent plate edge.

So that the spring elasticity of the at least one spring plate can be utilized over the largest possible part of its longitudinal extension, it is provided that the at least one slot provided on the carrier widens in the direction of the slot opening from the slot base.

In this case, the assembly of the at least one spring plate and, if necessary, replacing this spring plate, for example, a modified spring force is desired, even easier if the provided on the support and / or the holder, at least one retaining slot with the exception of the slot bottom on three sides is open ,

A particularly advantageous embodiment of the invention provides that the at least one distribution device has at least two pivot arms, which are preferably oriented in the longitudinal direction of the sports device and in particular laterally spaced from each other. Due to the at least two, laterally spaced apart pivot arms, the angle required in particular during cornering or on steep slopes between the carrier on the one hand and the sports equipment on the other hand can be particularly well lead and control.

In order to securely hold the at least one spring or damping element between the carrier on the one hand and the sports device on the other hand, a preferred embodiment according to the invention provides tion that the pivot arms are arranged on both sides of the at least one spring or damping element.

If the at least one spring or damping element is designed as a spring plate, this spring plate can practically be inserted into the holding slots on the carrier and on the holder, without subsequent screwing down of the spring plate being necessary if the pivot arms arranged on both sides of the at least one spring plate Secure at least one spring plate preferably in the retaining slots on the carrier and on the holder.

A particularly advantageous embodiment according to the invention provides that the pivot arms are each pivotally mounted on both sides and in particular laterally on the holder and on the carrier via a pivot axis serving as a joint.

A development according to the invention of its own worth-worthy significance provides that the pivot axis of at least one joint of the joint arrangement is positionally variable such that the distance between the one longitudinal side of the carrier and the sports device, for example, by an inclined position of the sports device in the Compared to the distance of the other longitudinal side of the carrier reduced or enlarged.

The hinge assembly of this further embodiment according to the invention has at least one joint whose pivot axis is so variable in position that the distance between see one longitudinal side of the carrier and the sports equipment compared to the distance: the other longitudinal side of the carrier is reduced or enlarged. Thus, by a change in position of the pivot axis of at least one of the joints of the Joint arrangement of the distance of the carrier to the sports equipment on its one longitudinal side in comparison to the distance on its other longitudinal side are enlarged and reduced so that the sports equipment is characterized in steep slopes or especially in short-curved tight corners by a much improved directional stability. When cornering, the distance of the carrier should increase on its inner side located on the inside of the curve and / or additionally or instead reduce on its long side outside the curve. .:

In order to be able to effect a positional deviation of the pivot axis on at least one of the joints of the joint arrangement, it is possible for example that the pivot axis of the at least one joint of the joint arrangement can be changed in position by means of an eccentric.

The driving behavior of the adjusting device having sports equipment according to the invention can also be subsequently adapted and change according to the individual needs or wishes when the at least one eccentric axle having thru axle is interchangeably held on the holder and / or the carrier (are).

In addition to or instead of at least one positionally adjustable joint, a further development according to the invention provides that at least one distribution device of the sports device has at least one spacer defining the minimum distance of the carrier to the sports device, and that the at least one Ab - Standhalter is designed so that at a minimum distance of the carrier to the sports equipment, the distance between the one longitudinal side of the carrier and the sports equipment compared to the distance of the other longitudinal side of the wearer reduced or enlarged is. Also in this further embodiment, it is achieved with the aid of the at least one spacer that the carrier deflected in the direction of the sports device occupies on its one longitudinal side a reduced or enlarged distance compared to the distance on the other longitudinal side of the carrier. Also in this embodiment can thus be achieved by a tilted position of the wearer relative to the sports equipment associated therewith a significantly improved steepness in steep slopes or in particular in short-drawn tight corners. In this case, the distance of the carrier should be increased on its inner side located on the inside of the bend and / or additionally or instead reduced on: its longitudinal outside located on the curve side during cornering.

In order to achieve the desired tilting position between the carrier and the sports equipment associated therewith, for example during cornering, it is expedient if the carrier and / or the swivel arms of the at least one distribution device act on the spacer with a minimum distance of the carrier to the sports device.

In order not to reach a tilted position between the carrier and the sports device with minimal distance between the carrier and the sports device, at least one distribution device can be assigned at least two spacers which differ from one another by different heights and / or by a different elasticity. However, a simple and advantageous embodiment according to the invention provides that the spacer rod-shaped or strip-shaped and is oriented transversely to the longitudinal extent of the sports equipment.

The spacer may be made of inelastic material, such as For example, be made of hard plastic or metal. However, in order to achieve smooth transitions with regard to the driving properties aimed for in steep or tight-drawn curves, it is advantageous if the spacer is made of elastic material.

It is possible that the spacer has a different elasticity in different subregions of its longitudinal extent, such that with a minimal distance of the carrier to the sports equipment, the distance between the one longitudinal side of the carrier and the sports equipment compared to the distance of the other longitudinal side of the carrier reduced or is enlarged.

Additionally or instead, it may be advantageous if the at least one spacer in the region of one longitudinal side of the sports equipment compared to the other longitudinal side of the sports equipment has different heights, such that at a minimum distance of the wearer to the sports equipment, the distance between the one longitudinal side of the wearer and the sports device in comparison to the distance of the other longitudinal side of the carrier is reduced or enlarged. Such an embodiment makes it possible to produce the spacer as a whole of the same material and in particular with a constant elasticity in all sub-areas.

A particularly simple and advantageous embodiment according to the invention provides that at least one spacer has an abutment surface inclined with respect to a plane lying in the running surface of the sports equipment.

A particularly simple and easy to install embodiment according to the invention provides that the at least one spacer is fixed to the sports equipment. Thus, the driving characteristics of the sports equipment according to the invention, for example, in steep slopes, in tight curves and in other extreme situations can adjust advantageously, it is useful if the flexibility of at least one spring plate is dimensioned so that the distance of the carrier sports equipment reduced during cornering. In this embodiment, the flexibility of the spring plate is dimensioned so that the distribution device allows an approach of the carrier to the sports equipment. During this approach movement of the carrier in the direction of the sports device, the pivot arms of the distribution device are pivoted in the direction of the sports device and optionally a spacer provided in individual embodiments of the sports device according to the invention becomes effective in the manner described above.

So that the steering movements exerted by the foot of the user can be safely transmitted to the sports equipment via the carrier, and thus the sports equipment according to the invention can absorb and distribute the loads acting on it well, it is expedient if the wearer with the sports equipment has at least two Distribution devices is connected.

In order to favor a slight tilting movement of the carrier relative to the sports device, it is advantageous if the plug-in axis is mounted in the guide openings provided on the holder and / or on the carrier holder via two, spaced apart in the longitudinal direction of the plug axis axis segments. In this case, a particularly advantageous embodiment facilitating the tilting movement desired, for example, in tight curves, according to the invention provides that the axle segments of the thru-axle mounted rotatably in the guide openings (18, 19) of holder and / or carrier holder are designed as spherical. shaped cross-sectional thickening are formed.

Advantageous embodiments according to the invention provide that the sports equipment is designed as a sliding body and in particular as a ski or as a roller carrier.

Damping elements of the distribution device shown in FIGS. 18 to 20, and 22 shows the distribution device from FIGS. 18 to 21, also shown here in the unloaded state. FIGS. 1, 2, 4, 9, 10, 12 to 16, 18 to 20 and 22 show a sports device 1 in various embodiments, which is designed here as a ski consisting of two skis pair of skis. The sports equipment 1 has at least one distribution device 2 for the forces and loads to be transmitted to the sports equipment 1. This at least one distribution device 2 connects the sports equipment 1 with a support 3 which carries a ski binding or the like coupling device 25 indicated in FIG. 13 by dashed lines for receiving the user. From Figure 12 it is clear that the carrier 3 is preferably connected via two, in the longitudinal direction of the sports device 1 spaced apart distribution devices 2 with the sports equipment 1. Each of the distribution devices 2 forms a, the carrier 3 with the sports equipment 1 connecting joint assembly, the at least one pivot arm 4, 5; 6, 7, in each case via a joint 8, 9; 10, 11 is pivotally connected at one end of the arm with the sports equipment 1 and at the other end of the arm with the carrier 3. By a pivoting of the pivot arms 4, 5; 6, 7 is the support 3 of the example shown in Figures 2, 3, 19 and 22 unloaded initial position against the restoring force of at least one elastic return element in a sports apparatus 1 approximated and in Figures 4, 5,12,13 and 20 shown compensating position movable, in which compensating position of the carrier 3 is approximated the sports equipment 1.

Each distribution device 2 has at least one restoring element, which restoring element is designed as a spring-elastically deformable spring or damping element. These elastically deformable spring elements are held on the one hand on the carrier 3 and on the other hand on ^: sports equipment 1. These spring or damping elements can be arranged or clamped between the carrier 3 and the sports device 1 such that a stable and spursichere connection between the carrier 3 and the sports equipment 1 is ensured even if each of the distribution devices 2 only one or each two pivot arms 4, 5; 6, 7 has. At the same time, however, such a spring or damping element also has sufficient inherent elasticity in order to transmit the shocks and vibrations acting on the ski only damped onto the carrier 3 and the user held on the carrier 3. This at best only subdued transmission of shocks and vibrations is perceived by the user as significantly increased ride comfort.

While the spring or damping elements of the distribution device shown in FIGS. 18 to 22 as elastically deformable tubes 32; 33 are formed, the spring or damping elements of the distribution device shown in Figures 1 to 17 as a resilient elastic spring plate 12; 13 designed.

Each of the elastically flexible spring plates 12; 13 of the distribution devices 2 shown in FIGS. 1 to 17 may be made of any suitable resilient material. Thus, the spring plates 12; 13, for example, also made of carbon material. In the embodiment shown here, the spring plate 12; 13, however, designed as a spring steel plate.

To the at least one spring plate 12; 13 on the one hand with sufficient rigidity and stability and on the other hand with a satisfactory spring elasticity, can the spring plates 12; 13 have an edge-forming or molding and additionally or instead - as here - at least one plate opening 14, which plate opening of the spring plate 12; 13 gives a defined flexibility. Here, in the embodiments of the sports device 1 shown here, the flexibility of at least one spring plate 12; 13 so dimensioned: that reduces the distance of the carrier 3 to the sports equipment 1 during cornering. In order to securely and firmly connect the distribution device 2 provided between the carrier 3 and the sports equipment 1 to the sports equipment 1, the distribution apparatuses 2 shown in FIGS. 1 to 22 have at least one holder 15 held on the sports equipment 1, which has at least one Joint 8, 9 with the at least one pivot arm 4, 5 is connected.

In the case of the distribution devices 2 shown in FIGS. 1 to 17, at least one holding slot 30, 31 is provided on the carrier 3 and on the at least one holder 15. To between the carrier 3 and the at least one holder 15, the resilient elastic spring plate 12; 13 to accommodate and fix, is the at least one spring plate 12; 13 with its adjacent plate edge inserted into the retaining slots 30, 31 Thus, the spring elasticity of the at least one spring plate 12; 13 can be used over as large a portion of its longitudinal extent, the at least one provided on the support 3 slot 30 widens from the slot bottom in the direction of the slot opening. It can be seen from FIG. 9 that the at least one holding slot 30, 31 provided on the carrier 3 and on the holders 15 is open on three sides, with the exception of the slot base.

The ^{'distribution} devices shown in FIGS. 1 to 22 2 here have at least two, in pairs mutually parallel pivot arms 4, 5; 6, 7, which are oriented in the longitudinal direction of the sports equipment 1 and in particular laterally spaced from each other. Since the pivot arms 4, 5 and 6, 7 are respectively arranged on both sides of the at least one spring or damping element, these pivot arms 4, 5 on the one hand and 6, 7 on the other hand arranged between them spring or damping elements, for example, in the retaining slots 30, 31 held carrier plates 12; 13, on the carrier 3 and on the holders 15.

The pivot arms 4, 5; 6, 7 are pivotally supported laterally on both sides of the carrier 3 and on their assigned holder 15 via a pivot axis serving as a joint 8, 9 or 10, 11 respectively. In this case, the pivot axis of at least one of the joints 8, 9; 10, 11 of the hinge assembly such variable position that the distance between the one longitudinal side of the support 3 and the sports equipment 1 in comparison to the distance of the other longitudinal side of the carrier 3 is reduced or enlarged.

The distribution devices 2 of the sports device shown in the figures can each be assigned a spacer 27, 27 '. Such a spacer 27, 27 * can determine the minimum distance of the carrier 3 to the sports equipment and is preferably designed so that at a minimum distance of the carrier 3 to the sports equipment 1, the distance between the one longitudinal side of the carrier 3 and the sports equipment 1 in comparison is reduced or enlarged to the distance of the other longitudinal side of the carrier 3. The embodiments of the sports equipment 1 shown in FIGS. 1 to 22 are characterized by a significantly improved directional stability in steep slopes and, in particular, in tightly drawn curves. The aim is the distance 3 on his Enlarge longitudinally on the inside of the curve and, in addition, or on its long outside on the outside of the curve, reduce it. In the embodiment shown in Figures 12 to 16 act on the pivot arms 4, 5; 6, 7 in the region of the carrier 3 facing joint 10, 11, the spacer 27, 27 ^λ , when the carrier 3 to the sports equipment 1 takes the specified minimum distance. The spacer 27, 27 'is here rod-shaped or strip-shaped and oriented transversely to the longitudinal extent of the sports equipment 1. From the results shown in Figure 14 to 16 embodiments, it is apparent that the spacer 27, 27 ^λ may be made of any suitable material, optionally also of metal. However, spacers 27, 27 ^x , which are made of elastic material, are preferred in order to achieve the smoothest possible transition of the driving behavior that adapts to the specific driving situation. It is clear from a comparison of FIGS. 14 and 15 that the spacer 27 ^v shown there has a different elasticity in different subregions 28, 29 of its longitudinal extent, such that with a minimal distance between the carrier 3 and the sports equipment 1 the distance between the one Longitudinal side of the carrier 3 and the sports equipment 1 compared to the distance of the other longitudinal side of the carrier 3 is reduced or enlarged. In contrast, a deviating embodiment 27 of the spacer is shown in Figure 16. The spacer 27 shown in FIG. 16 has different heights in the region of one longitudinal side of the sports equipment 1 compared to the other longitudinal side of the sports equipment 1, such that the distance between the one longitudinal side of the wearer is at minimum distance between the wearer 3 and the sports equipment 1 3 and the sports equipment 1 in comparison to the distance between the other longitudinal side of the carrier 3 is also reduced or enlarged. Leave the joints 8, 9; 10, 11 sufficient clearance of the support 3 relative to the sports equipment 1, in particular in the transverse direction of the sports equipment 1, the spacers 27, 27 ^v sufficient to the handling of the sports equipment 1 in steep positions or in tight curves in the desired manner improve. However, the embodiment shown: in which, in addition to the spacers 27, 27 ', the pivot axis of at least one of the joints 8, 9; 10, 11 of the joint arrangement of each distribution device 2 is positionally variable such that the distance between the one longitudinal side of the carrier 3 and the sports device 3 in comparison to the distance of the other longitudinal side of the carrier 3 is reduced or increased.

To such a change in position of the pivot axis of at least one of the joints 8, 9; 10, 11 to be able to do, the pivot axis of at least one of the joints 8, 9; 10, 11 of the joint assembly by means of an eccentric position variable. In the exploded perspective view in Figure 9 is particularly well seen that the both sides of each holder 15 arranged pivot arms 4, 5; 6, 7 with the holder 15 thereto is rotatably guided via a common plug-in axis 16 in at least one of the two guide openings of each holder 15 with an eccentrically arranged as an eccentric axis segment 17. In FIGS. 1 to 10, it can be clearly seen that the swivel arm 4, 6 adjacent to the at least one eccentric axle segment 17 is connected in a rotationally fixed manner to the plug-in axle 16.

In this case, an embodiment (not shown here) can also have a plug-in axle 16, each of which is connected to an eccentric axle segment 17 in the guide openings of the holder 15. is orders. The eccentricity of the two, in such a plug-in axis ^16: disposed axis segments 17 may be tuned so in opposite directions to each other that the distance between the one longitudinal side of the carrier 3 and the sports device 1 accession example by a caused during cornering inclination of the sports device in comparison to the Distance between the other longitudinal side of the carrier 3 is reduced or enlarged. Due to the eccentricity of the pivot axis of the pivot arms 4, 5 serving eccentric axis segments can be achieved that the sports equipment 1, for example, in tight curves against the user-carrying carrier 3 has an increased angular position, which further favors such tight cornering and ensures. By acting on tightly curved curves on the sports equipment 1 contact pressure is a compression of the sports equipment 1 held distribution devices 2 - regardless of the radius of curvature - and an edge of the carrier 3 relative to the sports device 1 causes.

FIGS. 10 and 12 show a preferred embodiment of the sports device 1 according to the invention, in which two distribution devices 2 with parallel pivoting arms 4, 5; 6, 7 are provided. The Schwenkarm- pairs of the distribution devices 2 are held by means of a respective holder 15 at a distance from each other on the sports equipment 1 and the holder 15. These Schwenkarm- pairs 4, 5; 6, 7 ensure that the carrier 3 during compression of the Verteilvorvor- tions 2 in almost unchanged parallel position to the longitudinal direction of the sports equipment 1 can approach the holders 15. The carrier 3 here has a carrier plate 20, which on its underside each have a carrier holder 21 for each of the pivoting plates. arm pairs 4, 5; 6, 7 has. On the support holders 21 of the support 3, the retaining slots 30 for the spring plates 12, 13 are provided. In FIG. 2. the sports equipment 1 shown in a starting position in which no centrifugal forces act on the distribution device 2 of the sports equipment. This initial position corresponds for example to a straight ahead of the user with the help of the sports equipment 1. In this case, the user carrying the carrier 3 by means of the spring plate 12; 13 held in a neutral position. In this neutral position, the eccentric provided here on one side and shown in more detail in FIG. 3 is not yet effective. When cornering act on the distribution device 2 of the sports equipment 1 centrifugal forces, which press the carrier 3 in the direction of the sports equipment 1. In this case, the spring plate 12; 13 under tension. By acting transversely to the sports equipment forces and the spring plate 12; 13 applied and energized. In this case, the position of the pivot axis of at least one of the pivot arms is changed in such a way that increases the distance of the carrier from the sports equipment 1 on the inside of the curve located longitudinal side of the curve compared to the outside of the curve beam longitudinal axis. By this one-sided increased angular position of the support 3 relative to the sports equipment 1, which can be. Favored by the spacers 27, 27 ', the directional stability of the sports equipment 1 is also increased in a tight cornering. This increased angular position of the carrier 3 relative to the sports equipment 1, which is indicated on the right side of Figure 4, causes the initiated cornering drove with less effort and can also be discharged again. In Figure 5, it is indicated that the one-sided, for example, in cornering increased distance of the carrier 3 from the sports equipment 1 can also be dimensioned comparatively small in order to still make noticeable to the user by a noticeable improvement in driving characteristics. In the figures ren 9 and 11, the thru-axle 16 in different versions with their here provided on one side and arranged eccentrically axis segment 17 can be seen. For reasons of clarity, a representation of the required spring plate 12; 13 waived. The inside of the sports equipment 1 is here on the side facing the viewer. From a comparison of the figures. 3 and 5 it is clear that with a deflection of the carrier 3 and directed in the direction of the sports device 1 pivotal movement of the pivot arm of the eccentric formed by the axis segment 17 moves continuously downwards. Even with a small axis rotation of the thru-axle 17, which adjusts itself by the centrifugal forces acting, for example, during cornering, the distance between the carrier 3 and the sports equipment 1 increases, as a result of which an increased angular position is established. It is a particular advantage of the distribution devices 2 arranged on the sports equipment 1 that they can also compensate and dampen unpleasant vibrations, for example when driving on uneven or icy ski slopes.

While in the support 3 shown in Figs. 1 to 16, the support plate 20 on the one hand and the holding slots 30 for the spring plates 12, 13 having carrier holder 21 on the other hand separately formed components, the retaining slots 30 for the spring plates 12, 13 in the shown in Fig. 17 carrier 3 incorporated directly into the sports equipment facing flat side of the carrier 3. From the perspective view of individual parts in FIG. 17, it is also clear that the plug-in axles 16 are connected to one of the mutually paired pivoting arms 4, 5 to form a fork-shaped component, the free axle ends of the stub axles 16 held on the pivoting arm 5 being correspondingly aligned or bearing opening on the associated adjacent pivoting arm 4 a can be set and fixed.

The distribution device 2 shown in FIGS. 18 to 22 has spring or damping elements which are each designed here as an elastically deformable tube 32, 33 oriented transversely to the longitudinal extent of the ski 1. It is clear from a comparison of, for example, FIGS. 21 and 22 that the tubes serving as spring or damping element of the distribution device shown in FIGS. 18 to 22 are arranged on opposite connecting sides 34, 35 between the carrier 3 of the distribution device 2 on the one hand and the sports equipment 1 and in particular the mounted on the sports equipment 1 holder 15 on the other hand are held. While the tubes 32, 33 serving as spring or damping elements have an at least approximately circular cross-section in the unloaded state shown in FIGS. 19 and 22, these tubes 32, 33 deform elliptically in the loaded, ie spring-loaded state according to FIG. In a vertical pressure on the carrier 3, this moves slightly downwards or counter to the direction of travel to the rear corresponding to the rotational circle D shown in Fig. 20, so that located between the carrier 3 and sports equipment 1 pipe sections 32, 33 are deformed elliptical. By a corresponding eccentricity of at least one of the pivot axes of the pivot arms 4, 5; 6, 7 and / or by at least one transverse to the ski longitudinal axis inclined spacers, the pivot axis of at least one joint 8, 9; 10, 11 of the joint arrangement in the distribution device 2 shown in Fig. 18 to 22 also such Lagever- changeable that the distance between the one longitudinal side of the carrier 3 and the sports equipment 1 in comparison to the distance of the other longitudinal side of the carrier 3 is reduced or enlarged , As a result, it is also possible to use the structure shown in FIGS. 18 to 22. Distribution device 2 have achieved the advantages already described above with regard to damping properties and tracking accuracy of the sports device 1 equipped with such a distribution device.

By comparing FIGS. 6 and 11, it can be seen that the stub axle 16 is mounted in the holder 15 via two axle segments 17, 26 which are spaced apart from one another in the longitudinal direction of the stub axle 16. In order to promote tilting of the carrier 3 relative to the sports device 1 and, at the same time, the pivotal movement of the pivoting arms 4, 5; 6, 7, it is provided in the embodiment of the plug-in axle 16 shown in FIG. 12 that this plug-in axle 16 in each case has a spherically shaped cross-sectional thickening in the area of axle segments 17, 26 serving as bearing points. These spherically shaped cross-sectional thickenings on the axle segments 17, 26 of the thru-axle 16 shown in FIG. 12 act practically in the manner of a ball joint.

The sports equipment 1 can be designed as a sliding body and, for example, as a roller carrier or, as here, as a ski.
