TECHNICAL AREA

The invention relates to a damping system for a gliding board, in particular for a snow gliding board for skiing, with which the most effective and immediate damping of the gliding board can be realized. In particular, the invention relates to a damping system according to the preamble of patent claim 1.

The invention relates to a gliding board with a damping system between a binding and the gliding board and optionally also with a connection system. The damping system is preferably designed for snow gliders and suitable for damping or also cushioning a relative movement or vibrations of the gliding board. The optional connection system is intended for the same type of snow gliders and suitable for mounting a shoe on the snow glider, especially in alpine skiing, especially racing ski, in particular according to the World Cup safety standard ("Equipment Rules FIS"). The connection system and / or the damping system is, for example, also designed for use in freestyle or rocker skis or in new school skis.

In particular, the invention also relates to a system which keeps the gliding board in the dynamic state particularly quiet, can dampen self-resonant vibrations and thereby flex as freely as possible unhindered. The system may include the connection system in addition to the damping system.

BACKGROUND OF THE INVENTION

The patent DE 10 2012 206 881 B3 describes a device for connecting a base plate to a ski, wherein the base plate has a recess with a slot-shaped opening.

The patent application DE 10 2006 034 869 A1 describes a ski with two rails with interruptions in which a bond can be locked by moving.

The publication DE 199 40 182 A1 describes a damping with a lever, by means of which the degree of an effective Verschiebehubs can be changed. The lever is used in particular to increase the stroke. The assembly takes place directly on a binding plate, so that a longitudinal movement of the binding plate is damped. The increase in the stroke can take into account the comparatively small relative movements of the binding plate.

The publication DE 102 16 056 A1 describes a damping device in which two damping elements are arranged in a receptacle of a base plate or in a separate abutment. The damping device is specially designed with regard to the type of base plate.

The patent US 5,931,480 A describes a damping system with lever mechanism. The publication WO 2007/022923 A2 describes a damper which is mounted by means of a toggle lever on a ski. This patent discloses a damping system according to the preamble of claim 1. The prior art discloses damping systems for sliding boards which cooperate with a binding plate and are actuated by the relative movement of the binding plate or bearing points of the binding plate. It is caused a relatively small relative movement. The respective damper is supported on the ski. The present invention, in contrast, relates to a device or system which also facilitates movement of the gliding board in the Dynamic condition particularly good and immediately damped and the sliding board can optionally flex more free than was previously possible. In this case, large strokes can be generated and the damping can be done comparatively sensitive and immediate.

The object is to provide a damping system optionally in conjunction with a connection system which can ensure the most direct possible damping, in particular also in conjunction with a good controllability of the sliding board by a (ski) driver. As far as possible, a particularly exact damping or damping designed for specific driving situations should also be possible. In particular, the object can also be seen to conceive a system for a gliding board, in which a damper acts in a particularly effective manner at the interface between the gliding board and a binding plate, even if unimpeded flexing of the gliding board should lead to an optimized handling, in particular even at higher speeds in racing. Because the driving behavior is highly dependent on the damping properties of the sliding board, and the control of the sliding board should not be complicated by the fact that the sliding board can not be well damped in particularly free flex. It is advantageous, especially with regard to an application in recreational sports, although a cost-effective design or manufacture of the device or the system can be ensured, and / or if the number of parts can be kept low, and / or if the damping system can be easily adapted to a specific purpose or driver. Finally, a simple construction of the damping system or a high degree of robustness and thus load capacity is also advantageous.

SUMMARY OF THE INVENTION

This object is achieved by a damping system according to claim 1. Advantageous developments of the invention are explained in the subclaims.

A damping system for a gliding board, in particular for a snow gliding board for skiing, comprises a base plate extending along a longitudinal axis of the gliding board with an upper side on which a shoe or a binding can be arranged, and with a lower interface to the gliding board on which the Base plate is rotatably mounted in at least one mounting point on the sliding board, and a damper arranged for damping a relative movement between the sliding board and the base plate.

According to the invention, it is proposed that the damper can be supported independently of a mounting of the base plate at a point not equal to the mounting point in front of and behind the base plate on the sliding board, in particular via a force or motion-transmitting element acting in each case in the front and / or rear region of the sliding board. wherein the relative movement to be damped is transferable to the damper without translation, and wherein the damper is held on the base plate. In this case, the damper is arranged to ensure a damping of a relative movement between the sliding board and the damper. The force-transmitting element can be arranged independently of the base plate and separately. The damper itself can be arranged freely from the sliding board.

In other words: not the base plate actuates the damper, but at least one additional force or movement-transmitting element such as a push rod, which can be coupled as far as possible at the front or rear of the sliding board in one point. A movement of the sliding board relative to the base plate can be damped by this element or one or more push rods from the damper before the movement is transmitted to the base plate. The relative movement of the push rods is greater than a relative movement between the sliding board and the base plate, so that the damper can act particularly effective or can be adjusted exactly. Bending / flexing of the gliding board is damped even before a shock is introduced into the base plate. The driver is thus comparatively quiet on the The sliding board. The damping function is largely independent of a relative movement between the base plate and the sliding board.

In contrast, in many previously known damping systems actuation of the damper on the base plate. The damping is relatively ineffective, since only small relative movements of the base plate or only small strokes can be damped. Or else it must be a lever mechanism or other translation provided.

The support of the damper independently of the base plate or in points far in front of or behind the base plate also allows the base plate as free to move relative to the sliding board on the sliding board to store, which favors free flex. This allows a particularly motion-free bearings of the base plate on the sliding board, be it in the longitudinal direction and / or height direction. The baseplate can be decoupled from the gliding board or relocated relative to the gliding board without necessarily affecting the nature of the damping. Holding the damper to the base plate allows decoupling from the sliding board. The damper can follow a relative movement of the base plate and thereby also be aligned by the base plate.

According to an advantageous embodiment, the damping system is adapted to direct a power flow on a path from the point in front of and / or behind the base plate of the sliding board first on the damper and only then in the base plate. As a result, the base plate can be easily decoupled from the sliding board, without affecting the damping function.

The damper preferably cooperates with the sliding board via at least one push rod engaging in a front or rear region of the sliding board. The movement of such a force-transmitting element can be transmitted directly - without translation - to a reciprocating piston or a damping medium of the damper. The push rod can run all the way forward to a tip or bow of the sliding board or completely backwards to an end or rear of the sliding board.

As a "sliding board" is to be understood preferably a device by which an individual on a substrate such. Snow, ice or even sand sliding can move. For this, the individual can optionally use one or more sliding boards.

As "base plate" is preferably to be understood a binding plate or a device which is adapted to couple a binding or other means for receiving a shoe or foot in a predefinable position on a sliding board. The base plate may be formed substantially rigid. A certain bending or damping characteristic of the base plate is not required.

According to an advantageous embodiment, the damper is arranged above the sliding board and below the base plate or in the base plate, wherein the damper is preferably arranged freely from the sliding board. This arrangement enables a damping of different relative movements in a simple manner. In addition, the damper can be arranged in an advantageous position, even if the sliding board heavily flext.

According to an advantageous embodiment, a distance between the lower interface and the surface of the sliding board is adjustable in the loaded state, in particular a distance of at least 15mm, for example about 20mm. This can ensure that a bending of the sliding board is not affected by the base plate or the damper.

It can be provided in those sections of the base plate, which overlap the mounting points front or rear, respectively in the unloaded state, a distance or at least a radius, in particular to provide a free space in which a relative movement of the sliding board can take place. The base plate can for the purpose of transmitting forces and shocks (three to five times the acceleration of gravity in jumps) lie directly on the sliding board, at least laterally outside, in particular in the region of tabs, and can provide a cavity for the arrangement of / a damper. Upwards and downwards, the base plate can be open in the area of the cavity.

According to an advantageous embodiment of the damper is held on the base plate under the base plate. The damper may e.g. abut by means of a lateral surface on the underside of the base plate or in a corresponding cavity. In this case, the damper can be positively and / or non-positively connected to the base plate, in particular via a clamp or clamping strap. This also allows easy (dis) assembly.

The adhesion can be e.g. be ensured by a mounting connection between the damper and the base plate. The positive connection may e.g. be achieved by a corresponding recess in the base plate, in particular to transmit all introduced via the push rod forces directly on the damper. The coupling to the base plate and the decoupling of the sliding board also allows a good, direct driving feel with a particularly freely movable base plate.

According to an advantageous embodiment of the damper is arranged free from the sliding board, in particular spaced from a portion of the sliding board under the base plate. The damper may be displaceable in a height direction relative to the sliding board. This allows the damper to be decoupled from the gliding board so that the damper can move away from the gliding board with the base plate. This also allows a height adjustment. The damper is then coupled only via force-transmitting elements in fixed points in a front and / or rear of the sliding board to the sliding board, in particular at corresponding holes or slots. The damper can be firmly mounted / fixed to the base plate, although the damping effect can be transmitted substantially via the push rods.

According to an advantageous embodiment, the relative movement to be damped is transferable without translation to the damper, wherein the damping function is ensured by the amount of relative movement of the corresponding force or motion-transmitting element. This provides a very direct mechanism without lever or deflecting mechanism. This also promotes easy adjustability.

According to an advantageous embodiment, the damper or at least one damping function of the damper free Leerhubfrei, in particular load-discharging Leerhubfrei, in particular by the use of one or more membranes. This provides advantages in the driving characteristics and also in the design of the elements acting on the damper, in particular in the arrangement or selection of a suitable length of the push rods. Without idle stroke or thanks to greatly reduced idle stroke, a push rod can be kept shorter. The Leerhubfreie mode of operation also provides advantages in terms of driving characteristics and the most direct driving experience. It can also be a damping of only small relative movements or vibrations of the sliding board.

According to an advantageous embodiment, the damper is arranged to perform two damping functions in opposite directions, wherein the damping functions are preferably independent and / or adjustable, wherein the damper is preferably arranged between two elements to be damped or motion transmitting elements, in particular between two push rods of the damping system, preferably at least approximately centrally in the longitudinal direction under the base plate. In this case, the damper a direction-dependent and / or movement-dependent, adjustable Have damping characteristic, in particular a different in opposite directions damping characteristic. An attenuation characteristic of the damper may be determined, for example, by at least one of the following arrangements: a front of the push rods is mounted on the damper unbeaten load introduction; and / or the front push rod is mounted on the shock absorber damped load; and / or a rear of the push rods is load-initiating damped mounted on the damper; and / or the rear push rod is mounted on the damper load-discharging undamped.

According to an advantageous embodiment of the damper is also rotated by 180 ° mountable and / or opposite ends or coupling points of the damper are formed symmetrically to each other. As a result, an attenuation characteristic can be inverted in a simple manner.

According to an advantageous embodiment of the damper by means of an intermediate element, preferably by means of a piston rod, connected to the (respective) force-transmitting element, in particular adjustable via a threaded coupling, wherein preferably the hardness of the sliding board via the threaded coupling is adjustable, preferably manually. The hardness can be adjusted by the driver himself. The driver is not limited to factory settings.

According to an advantageous embodiment, at least one damping function of the damper can be switched on or off, in particular by positive locking or by means of a positive locking element. This allows a reliable robust reversible mechanism for adjusting the damper.

According to an advantageous embodiment, one or two damping functions of the damper are each selectively load-initiating or load-releasably adjustable damping, in particular direction-dependent as a function of a damping direction, in particular by rotating a diaphragm or a piston rod of the damper or a respective damping element. This adjustability results in many variants of an attenuation characteristic, in particular at least four variants per damping element: load-introducing (un) attenuated or load-discharging (un) attenuated.

According to an advantageous embodiment, the damper has at least one membrane and is controllable or adjustable by means of the at least one membrane, wherein the membrane is preferably positionally, in particular rotationally fixed, positionable in at least two predefinable rotational positions, in particular by means of a piston rod.

Preferably, the membrane has a passage for a piston rod, so that the membrane can be arranged and guided on the piston rod. Preferably, the membrane has a passage, in particular an opening, for the damping medium. The membrane may have passages or openings or holes which are formed congruent to corresponding passages, openings or holes in the corresponding reciprocating piston of the damper. Preferably, the damper on two membranes, in which the front and the rear membrane have the same size openings for the passage of the damping medium to spring damped. As the reciprocating piston is moved toward the diaphragm side, the diaphragm can close / seal the larger flow hole of the reciprocating piston. If the reciprocating piston is moved in the other direction, then the damping medium pushes the membrane away from the reciprocating piston so that the damping medium can flow unimpeded through the reciprocating piston and can be moved without damping and with little resistance.

According to an advantageous embodiment, the damping system comprises two damping devices and a spring element, wherein the damper is designed as a three-function damper, which has a spring function and two Damping functions fulfilled. This also provides advantages in terms of a specific adjustment of the damping properties of the front or rear portion of the sliding board. The spring element is preferably arranged between two damping elements, in particular between two reciprocating pistons.

According to an advantageous embodiment, the damper comprises two reciprocating pistons, between which a / the spring element is arranged, wherein by means of the spring element, the hardness or flexural rigidity of the sliding board is adjustable, in particular by adjusting the relative position of the at least one force-transmitting element in the longitudinal direction relative to the spring element. This serial arrangement of three components of the damper allows a convenient interaction of three functions, especially in an advantageous design in an arrangement under the base plate or in the base plate.

According to an advantageous embodiment, the lower interface for a predefinable relative movement between the base plate and the sliding board is set up in response to a bending of the sliding board, in particular by a relative rotational movement of the base plate about at least one mounting point on the sliding board, wherein the damper is arranged, in addition to the relative movement between the sliding board and the damper also to dampen the relative movement between the base plate and the sliding board. As a result, the base plate can be stored damped on the sliding board, even if the base plate is mounted motionless in the longitudinal and vertical direction. In this case, a damping of the sliding board on the base plate, even at a strong translational compensation, at least to a small extent.

According to a further aspect of the invention, the damping system has a connection system with a slide guide, wherein the lower interface is adapted for height adjustment of a height position of the base plate in a height direction orthogonal to the longitudinal axis, in particular by the base plate along the longitudinal axis in the slide guide or along a Guideway displaceable relative to the sliding board can be stored. In this case, the base plate in at least one mounting point can be rotatably storable. In this way, it can be ensured, on the one hand, that the sliding board can flex in the dynamic state over the entire length of the sliding board or can freely flex freely. On the other hand, it can be ensured that a driver of the gliding board is brought into an advantageous height position when bending the gliding board. This height compensation, the center of gravity of a driver of the sliding board in the height direction can be compensated, and automatically with the length compensation. Thanks to the height compensation, the top of the base plate in dynamic driving condition can be at least 10mm or even 15mm, 16mm higher than without height adjustment or as in static condition. A ski boot can be arranged much better spaced from the runway than in a connection system without height compensation.

In this case, the damper may be arranged under the base plate so that the height compensation does not affect a damping. Rather, the damper can be displaced by means of the base plate in an advantageous position with respect to force action position at a greater distance to the gliding board, especially in strong bending of the gliding board.

In racing, the height of the stance in relation to the ski slope is limited to a maximum value under static conditions (World Cup safety standard, in particular not more than 50 mm between the underside of the ski and the top of the base). The height adjustment according to the invention can cause a standing position above this maximum value in the dynamic state while driving and therefore, for example, makes it possible to have stronger cornering positions. This type of coupling or interface also allows a kind of cascade control of the position of the skier, or a kind of cascade control of the driving behavior or the sliding board by the driver, or a cascade control of the dependence between length and height compensation. The Cascade control can also be described as a gate control, since a mounting point can be guided in a slot, in a slot or in a groove or along a contour or curve. The term "cascade control" may also refer to a control of the driving behavior by the driver, in particular since the strength of the bend and thus the translation and the height position can be adjusted by the pressure exerted by the driver on the sliding board. The term "cascade" can also refer to a gradual, successive change.

The lower interface may in this case have at least two rigid rotary axis units, one of which (preferably the rear rotary axis unit) being able to compensate for a translatory relative movement between the flexing sliding board and the fixed base plate via any link or contour extending in the vertical direction. Although the binding is firmly connected to the gliding board, it allows the gliding board to flex or flex over the entire length of the gliding board. This arbitrary shape / contour can e.g. be concave or convex, be a hyperbola, ellipse or circle segment as well as an inclined plane. The contour also extends, at least in sections, in the vertical direction in order to enable the height adjustment. In previously known systems, a translational relative movement is made possible exclusively via one-dimensionally extending oblong holes, whereby no height adjustment can be realized and, moreover (especially with greater flex), a high friction occurs, which hampers the free formation of a bending line.

The snow glider, in particular alpine skis, comprises an elongate ski body and may further comprise a damping element integrated in the baseplate in the front and a further damping element for the rear part of the ski body having a different characteristic. The damping system preferably has at least three functions (three-function damper).

The patent US 5,129,668 A describes a mechanism with a lever which allows translation and rotation of a mounting point of a binding plate relative to the ski. The binding plate can thereby be decoupled from the ski, but the lever counteracts free flexing of the ski and thus prevents the desired free flex in the dynamic state. In addition, no satisfactory damping can be realized with this mechanism.

In the prior art, only binding plates are described, which allow only depending on the shoe size or the length of the binding plate an interrupted bending line or an affected or disabled flex of the sliding board (skis), i. the larger the shoe size or the longer the binding plate, the longer the area in which no flex in the dynamic state is possible. Thus, the ability to drive with the sliding board certain curve radii or compensate for any bumps, limited in a very detrimental way. When skiing, the load is transferred via the ski boot (or the sole). The ski boot pushes the front and back of the base plate and stiffens the ski thereby. Alone due to the rigidity of the ski boot no deformation is possible, even if the base plate would be flexible. The part of the ski covered by the binding / base plate, as a rule approx. 60cm, is therefore absolutely stiff. Only in front of or behind the binding or baseplate is it possible to flex the ski. In conventional systems, the stiffening influence of the binding on the ski becomes even stronger and more disadvantageous as the ski becomes shorter.

By contrast, the present invention, with optimized cushioning, can also provide free dynamic flex of the snowboard over the entire length, regardless of how tall / stiff the ski boot or how long the binding panel is. The sliding board can bend freely over the entire length, so that the entire sliding board can have a uniform radius of curvature. This is possible even under heavy load on the gliding board. According to the invention, a device can be provided which allows the snow sliding board to flex freely over the entire length largely independently of a load condition, thereby also allowing very good driving characteristics and improving control over the sliding board. Also The gliding board can work more flexibly and freer to compensate for bumps. In this case, the free flexing be ensured regardless of the length of the sliding board in the same advantageous manner. The strength or rigidity of the base plate / binding plate can be selected largely independently of the desired bending properties of the sliding board. Not least because of the advantageous arrangement and connection of the damper, the damping function can act very effectively and directly regardless of the extent of a height adjustment in different load conditions.

Also, the base plate can be better spaced from the ski by the higher height position. In other words: Even with strong bending, the base plate does not hinder the ski. This has advantages in particular with regard to an arrangement of the mounting points within the sole length. The power transmission between the driver and ski can always be done at the same points of application regardless of the degree of bending. The slotted guide according to the invention thus also allows a particularly advantageous arrangement of the force application points on the sliding board below the sole of a driver.

As a "connection system" is preferably a system to understand, which can ensure a connection of a (ski) shoe to the sliding board. Optionally, the connection system may also comprise or interact with a damping or a damping system. In particular, the connection system can be connected together with a damping system to an overall system, which can be arranged on the lower interface between a (ski) shoe and the sliding board.

A "guide slide" is to be understood as meaning preferably a device by means of which the base plate can be moved along a predefinable travel path, e.g. along a sectionally straight line and along a curve, guided relative to the sliding board and preferably at the same time can be stored. According to a preferred variant, the slotted guide, on the one hand, predefines the movement path and, on the other hand, also provides a bearing element or a bearing for a translation.

The slotted guide may have a provided in the base plate or in a mounting plate guide, contour or slot. If the guide or the slot is provided on a corresponding mounting plate, then a corresponding axis can be supported or supported in the base plate. If the guide or the elongated hole is provided on the base plate, then a corresponding axis can be supported or supported on a corresponding mounting plate.

Preferably, in addition to leveling a relative height position of the base plate in a height direction orthogonal to the longitudinal axis, the lower interface is also configured for a predetermined length compensation of a relative longitudinal position of the base plate on the sliding board in a longitudinal direction. Due to the length compensation, the center of gravity of a driver of the sliding board can be displaced in the longitudinal direction, wherein when cornering a forward movement can be supported. This provides advantages especially in racing. The driver can accelerate out of the bend, especially when carving, when centrifugal forces are converted into propulsion. The invention enables stronger skew, higher centrifugal forces and thus a stronger acceleration from the curve.

According to one embodiment, the degree of height adjustment is coupled to a translational movement between the base plate and the gliding board, wherein the slotted guide is adapted to proportionally or disproportionately adjust the height position as a function of the translational movement sections or completely along the slotted guide. As a result, the driving behavior can be adjusted individually, be it to a driver, be it in relation to certain driving situations or load conditions. The slotted guide can be provided in a simple manner with a specific contour or geometry and therefore allows one for certain driver or conditions specific translational motion path. The dependence can be proportional, for example, by means of a straight oblique contour, or over-proportional or underproportional by means of an obliquely arranged and additionally curved contour.

The coupling of the height adjustment to the translation in the longitudinal direction also has the advantage that the displacement in the height direction can be done in a damped way. In other words, the damper dampens not only the gliding board, but also the relative movement of the base plate and thus the displacement of the center of gravity of the driver. Thus, a particularly quiet driving behavior can be ensured.

According to one embodiment, the lower interface is designed such that the base plate in the direction of the longitudinal axis translationally mounted on the sliding board can be mounted, in particular in a rear mounting point. This allows a length compensation done at an advantageous mounting point. The translation in the rear mounting point favors an acceleration of the driver or a guide of the ski, especially when cornering. In a translation at the rear mounting point, the base plate is displaced to the rear in a bending of the sliding board, since the distance between longitudinally offset on the sliding board provided mounting points decreases. An axis of rotation shifts in the slotted guide forward.

According to one embodiment, the lower interface for a dynamically freely changeable bending line of the sliding board is set up independently of the base plate and can be connected to the sliding board in such a way that the bending line can be decoupled from the base plate, in particular with a uniform bending radius along the sliding board. The bending line is dynamically freely adjustable while driving, without being influenced by the interface or the base plate. A uniform bend radius provides a smooth ride and can also favor an acceleration of the driver, especially when driving out of a bend out. In this case, the base plate on the bottom rear and / or front geometrically be formed, in particular arched upward or beveled that the sliding board also behind the rear or in front of the front pivot / mounting point can flex freely upwards without touching the base plate. In particular, the base plate can be tapered or chamfered at the respective end.

The base plate may be formed independently of a certain bending stiffness of the sliding board as a substantially rigid, inflexible base plate.

According to one embodiment, the base plate at the lower interface at a first (preferably front) mounting point is rotatably mounted relative to the sliding board on the sliding board stationary relative to the sliding board and at a second (preferably rear) mounting point relative to the sliding board translationally displaceable, in particular axially displaceable in the longitudinal direction, the sliding board storable , In this way, on the one hand a fixed position of the base plate can be ensured on the sliding board, in particular at the front mounting point, on the other hand, the relative movement of the sliding board can be decoupled from the base plate. This can also ensure a particularly quiet position of a driver. The base plate need not follow any movement / bending of the sliding board. In contrast, the base plate in a lever mechanism, as in the patent US 5,129,668 A described during dynamic working of the sliding board strongly displaced, resulting in a restless position and difficult control result. Also, the weight of the driver counteracts a free Flexen.

According to one embodiment, the translational mounting of the base plate in the vertical direction and in the longitudinal direction is ensured by the slotted guide. In other words: The slotted guide allows supporting and stabilizing the Baseplate. An additional lever or any mechanics with moving parts is not required. This is particularly advantageous with regard to snow and ice or other foreign bodies. The system is therefore particularly robust.

According to one embodiment, the slotted guide has a contour in which the height adjustment during bending of the sliding board causes a height increasing with increasing bending height, in particular disproportionately or less than proportionally, at least in sections. As a result, the standing height of a driver when bending can be increased, so that a larger curved position can be realized. It is referred to bending about a point above the ground. The contour may be provided on / in the base plate or on / in a mounting plate.

According to one embodiment, the slotted guide is arranged to assign at least a specific radius of a bending line of the sliding board an exact height position of the base plate relative to the sliding board. This allows control of the driving characteristics with respect to specific load conditions or driving situations.

Preferably, a first (front) mounting point and a second (rear) mounting point of the lower interface are arranged at a distance from each other, which corresponds to a maximum length of a ski boot or a length of mountable on the base plate binding. Thereby, e.g. be provided three different binding plate sizes or base plate sizes, wherein the distance of the pivot points or mounting points e.g. in the range of 200mm, 280mm and 350mm. This arrangement of mounting points can also facilitate the placement of the force-transmitting elements or push rods.

According to one embodiment, the distance of two mounting points or axes of rotation on the sliding board in the longitudinal direction to each other is at most equal to or less than the length of a sole of a shoe mountable on the base plate. The mounting points are then arranged on the length limited by the ski boot, so under the sole of the ski boot. This makes it possible to arrange force application points in a small lever arm on the sliding board, so that the forces acting on the sliding board even less hinder the free flexing of the sliding board. It has also been found that very good driving characteristics can be achieved if the force application points or assembly points are arranged as possible below the bale or the heel of a foot of the driver. According to a variant, the distance is less than 90% of the sole length, or less than 85% or 80%, or even less than 70%. Depending on which driving characteristics are to be achieved, the distance can be selected to be particularly small. The base plate can be in one piece.

The base plate can be supported independently of the selected distance exclusively at two different longitudinal positions, in particular on the two axes of rotation or mounting points on the sliding board. This provides a great freedom of movement for the sliding board. In such an assembly, the bending line of the sliding board is not noticeably affected.

According to one embodiment, the link guide, in particular a rear tab, a contour or recess or recess or gate, by means of which a form of movement or a path of movement translational relative movement between the base plate and the sliding board for adjusting the height adjustment in dependence of the bend definable is. The slotted guide can provide a contour in which a specific radius of the bending line of the sliding board is assigned a precise height position. In other words: Thanks to a geometrically predefined contour, the base plate can be displaced along a predefined movement path relative to the sliding board. The height change can be adjusted in dependence of the displacement in the longitudinal direction. The shape of the contour is free selectable. The change in height can, for example, be proportional to the change in length, or disproportionately and / or disproportionately in sections.

The movement path can extend in a plane in two dimensions and be straight or at least partially curved, be it with a steady or unsteady course.

The contour can have one or more shapes from the following group: a downwardly curved shape, an upwardly curved shape, an obliquely arranged obliquely to the base plate shape, a hyperbola shape, an elliptical shape, or a circular segment Shape. The shape of the contour, in which a rotation axis of a rotary axis unit can be guided, can be based on the purpose to be achieved. Preferably, the geometry of the contour is such that, when flexing the sliding board, the standing height of a driver or a distance between the base plate and the underside of the sliding board is increased. Along an inclined plane, the height of the stand can be changed in a linear manner. Along an elliptical contour, the level can be changed so that in a first flex stage only a small change in the height of the stand, and that the height of the stand changes more and more with increasing bending. The height adjustment can therefore be specific as a function of a specific translational relative position. Due to the increasing height change in border areas, the driver can be particularly well accelerated when cornering with high centrifugal forces, the height adjustment is stronger with increasing forces, especially disproportionately.

Alternatively, the stand height can be changed with an elliptical shape such that a comparatively large change in the height of the stand takes place in a first flex stage, and that the height of the stand then changes less and less with increasing bending. In this way, the driver can be given a good control of driving characteristics even in the border area. At the same time, the driver's ski boot is already raised sharply even with small bends or with comparatively large bending radii, so that strong cornering situations can be achieved in many driving situations. This setting may e.g. also be advantageous on a course, which is comparatively "slow", ie in which, according to experience, not particularly extreme centrifugal forces occur.

According to one embodiment, the slotted guide has an oblong hole which also extends in the vertical direction and which is curved upwards or downwards for the height adjustment and / or is oriented obliquely to the base plate, or which has at least one radius of curvature and to one below the base plate or below Corresponding mounting plate arranged curvature center is curved, in particular with a radius of curvature greater than 7mm. The radius of curvature is preferably greater than a diameter of a pivot or a rotation axis of the slotted guide. In this case, a smaller radius of curvature can be selected if a particularly high height adjustment is desired. Preferably, the slot in the direction of the longitudinal axis to an extension which is at least three times the width of the slot or as the diameter of a roller device which is adapted to be performed in the slot. In this way, even with a relatively large flex or a relatively soft sliding board, a length or height adjustment of the position of the base plate or of the center of gravity of a driver can still take place in a border area.

According to one embodiment, the connection system, in particular the slotted guide, a sliding or sliding bearing and / or a roller or ball mechanism, by means of which in each case a length and height compensation can take place, in particular in a slot of the slotted guide. As a result, a low-friction translation can take place, and the bending line is not noticeably influenced. The roller or ball mechanism may comprise roller bearings or ball bearings, in which a rotation axis or a pivot pin in the respective mounting means is storable. The sliding element can eg be formed by a bolt with low static friction. The plain bearing provides high robustness, since only a few components relative movement must be made. The plain bearing can be formed for example by a particularly smooth, low-friction material pairing, for example POM or PEEK, PVC, glass fiber, carbon fiber, aluminum. In this case, a contour can also form sliding edges or leading edges of the sliding bearing.

According to one embodiment, the roller mechanism to a roller device which is geometrically formed corresponding to the slotted guide or the slot and is mounted on a pivot axis or a pivot. Preferably, the axis of rotation runs directly on rollers of the roller device, ie without an additional cage for the rollers.

According to one embodiment, the damping system comprises: one or two dampers or damping elements, each cooperating with a push rod, and a spring element; wherein the damper or the damping system is designed as a three-function damper, which performs a spring function and two damping functions, wherein the damping functions are preferably independent of each other or are adjustable.

In other words, the height compensation can be used in conjunction with a damping system. A damper, in particular three-function damper can be integrated into the base plate or be connected to the base plate, wherein the damper operates at least one push rod, which can be axially fixed in the front and rear end of the snowboard. The damper is designed to ensure the three functions of damping a flex in the front part of the gliding board, damping a flex in the back of the gliding board, and cushioning. The damper preferably has at least the following three components: a front damping element or a front Dämpfungskavität with reciprocating piston, a rear damping element and a rear Dämpfungskavität with reciprocating piston, and a spring element between the two damping elements. In this case, an attenuation characteristic on the front damping element can be adjusted independently of an attenuation characteristic on the rear damping element, so that it is possible to speak of three functions, namely two mutually separate damping functions and a cushioning function.

In the prior art, however, dampers can be found, which can attenuate in particular either load-initiating or load-discharging. On the other hand, the damper according to the invention can optionally damp load-initiating and / or load-discharging. In this case, the damper can be characterized by a diaphragm-controlled damping system. The damping system may be constructed based on different damping fluids. For example, the damper as a damping fluid, a gas, gas mixture, air, gel, or oil, or other liquids.

The damper preferably forms a functional element with the base plate. The damper can be operated via at least one push rod at the front and at least one push rod at the rear in the dynamic state. More particularly, the invention relates to a damping system in which at least one push rod is movably supported in the longitudinal direction of the sliding board over any length between the binding and the front sliding board, and in which another push rod is movably mounted in the longitudinal direction of the sliding board over any length of the rear sliding board is. The length of the respective push rod can be as large as possible, corresponding in particular at least approximately to a length corresponding to half the length of the sliding board. The length is e.g. in the range of 70% to 80% of the half of the length of the gliding board, e.g. in the range of 35% to 45% of the absolute length of the sliding board.

Hereinafter, individual preferred features of the damper will be described.

The damping system preferably has a respectively at the rear and front end on Schneegleitbrett fastened push rod. The push rods are preferably coupled at one end to the damper to the base plate.

According to a variant of the damper or three-function damper is an oil damper, which is controllable via a diaphragm. The damper is preferably connected to the front push rod so that it can not move freely and has an undamped function. As an "undamped function" can be described an arrangement in which a piston rod actuates a reciprocating piston in a Dämpfungskavität (in particular a damping cylinder) with low resistance and without damping. A load-introducing, undamped arrangement has the advantage that the sliding board can be guided more quickly over an obstacle (for example a snowdrift, a hump). An impulse of the gliding board is completely preserved and not dampened to keep the gliding board fast. This has advantages especially in racing.

According to an advantageous embodiment, the damper on a direction-dependent and / or motion-dependent damping characteristic, in particular a different in opposite directions damping characteristic, which is preferably set by means of two damping elements.

Preferably, the damping system has a valve control, by means of which a hardness of the damping of the damper is adjustable and adjustable, in particular manually or for or by the driver of the sliding board.

Preferably, the damper on two independently operating damping elements, in particular oil pressure damper, each with a specific damping characteristic.

The damper is preferably connected to the at least one push rod free of empty lifting, in particular with two push rods. The damper can be designed empty stroke in particular by means of a membrane or valve control. An empty lift-free (ie backlash-free) integration of the damper in the overall system has the advantage that the damper acts immediately. This is particularly advantageous in the small path lengths when bending the sliding board. Previous measures to increase the path lengths consisted in particularly long push rods or in a lever mechanism, as for example from the published patent application DE 199 40 182 A1 is known. A Leerhubfreie integration of the damper therefore not only allows advantages in driving characteristics, but the push rods can optionally be made shorter. A lever mechanism in the damper is not required. In this context, "damping-free" is to be understood as damping, in which a damping effect can be achieved immediately, that is, even at the smallest stroke. The term "empty lift" can also be understood as "play-free", ie without play or with no play. If an idle stroke occurs at all, it is at most a few percent, preferably less than 10% or 5%, with respect to the absolute stroke.

According to an advantageous embodiment, the damper is set up to be selectively damped only by load introduction or load discharge, in particular in each case specifically with respect to one of the push rods. In particular, the damping characteristic can be adjusted by a 180 ° rotation of the damper or by a 180 ° rotation of the reciprocating piston in conjunction with a diaphragm or by dispensing with a passage or an opening in the reciprocating piston. In the latter case, the damping works both load-initiating and load-discharging.

The damper is, for example, connected to the rear push rod and has an undamped function, and / or load-discharging free-lift connected to the front push rod and has a muted function, and / or load-initiating Leerhubfrei connected to the rear push rod and has a muted function. The damper can optionally load-initiating or load-discharging empty-haul be connected to the front or rear push rod and have a muted function. Preferably, the damper is attenuated load derating.

Preferably, the push rod has a thread, in particular an internal thread, which is formed geometrically corresponding to a thread, in particular an external thread of the piston rod. This allows a simple way of adjusting the damping characteristic.

Preferably, the push rod has a plurality of holes and / or a slot, by means of which / which the push rod is fixable in different relative positions in the longitudinal direction relative to the sliding board on the sliding board. This allows a simple way of adjusting the damping characteristic.

Preferably, the damper is formed so symmetrical at two free ends, that the damper is rotated by 180 ° with the other free end is mounted and thereby the damping properties are reversible. In other words, if previously the front damping element does not dampen the load and dampens the rear damping element, the damping characteristic is exactly the opposite when the damper is reversed, that is, the damper can now be frontally damped and load-unloaded. In this way, the benefits of a load dissipating undamped arrangement can be used for a particular application.

Preferably, the damper on a spring element, which is preferably arranged between the two reciprocating front and rear. The spring element can in this case e.g. a coil spring or an elastically deformable elastomer or another suitable elastic spring material, e.g. an elastically resilient foam.

Optionally, two separate damping elements, for example, oil dampers with different damping characteristics can be used.

Preferably, the degree of damping of the damper is adjustable, in particular by a membrane in a certain rotational position relative to the reciprocating piston is positioned so that a passage for the damping fluid can be regulated. By turning a piston rod, the opening of the passage can be increased or decreased.

Preferably, the damping system has a valve control which is designed to regulate the hardness of the damper. In this case, on a wall (damping wall) of the Dämpfungskavität (in particular of the damping cylinder), a survey or a paragraph or a protruding nose or a locking projection may be provided which engages in retracted stroke piston in a passage or an opening of the membrane. The wall is preferably an end wall or an end face of the damping cavity. By turning the piston rod, the opening of the passage can be increased or decreased. In this case, the respective diaphragm can be mounted rotationally fixed on the piston rod via a positive connection or a fit. The reciprocating piston is preferably not rotated in operation, but only pushed in and out, so that the membrane remains arranged at a constant position. Depending on the desired damping characteristic, the respective membrane can be arranged on the reciprocating piston, eg in front. If the diaphragm is arranged at the front on the lifting piston on a front side, the diaphragm can close / seal off a comparatively large passage (flow opening) during rebound, so that damping is particularly effective. It adjusts itself load derating a comparatively strong damping. In compression at the front, the membrane is opened by the flow of damping fluid, and the damping fluid can flow through the large passage, so that no damping or only a much weaker Damping is effected as in detail in relation to FIG. 7 is explained. It introduces load-inducing a comparatively weak damping (load-inducing undamped).

In particular, it can be caused by a rotation of the piston rod or the damper by 180 ° that the damping characteristics are changed such that the damping of load-initiating damping in load-diverting reversal reverses, and vice versa. The damping can thereby be adjusted in particular manually in a simple manner.

Preferably, the damper is formed of two individual dampers, which are each membrane-controlled.

Preferably, the respective reciprocating piston on sealing means, in particular a stationary on an outer circumferential surface of the reciprocating piston, for example in a corresponding groove, arranged O-ring. In this way, a seal of a respective chamber accommodating the damping medium or a compartment of the chamber can take place.

The aforementioned object is also achieved by a gliding board, in particular snow gliding board for skiing, with a damping system according to the invention. In this case, the damper is supported independently of a mounting of the base plate in a point before and / or behind the base plate via an engaging respectively in the front and / or rear region of the sliding board force or bewegungsübemagendes element on the sliding board, wherein the connection system preferably designed such that a bending line of the snow gliding board is independent of the base plate or the length of the base plate dynamically freely changeable, in particular shoe size or shoe hardness independent. This allows a particularly effective damping in conjunction with a height adjustment and optimized driving characteristics. The bending line is freely changeable, in particular dynamically while driving, and can form continuously along the sliding board, without being influenced by the base plate. Flexing can be done at any ski boot hardness; Usually, ski boots are available with a flex of 50 (soft) to 200 (hard, racing). In this case, the damper can be advantageously decoupled from the sliding board and arranged displaceably with the base plate and held on the base plate.

The present invention has an advantageous effect in many respects. A bending line can form undisturbed. The driver can take a stronger inclination. The driver is effectively accelerated out of the bend. The connection system can be made very simple and robust. Both optional height adjustment and damping can be easily adapted to specific riders or conditions.

DETAILED DESCRIPTION OF THE FIGURES

In the Fig. 1 an alpine ski (gliding board) 1 is shown, on which a connection system 10 and a ski boot 2 are mounted. The ski boot 2 is fastened in a ski binding 3. The ski binding 3 is mounted on a base plate 12 of the connection system 10. Between the connection system 10 and the alpine ski 1, a damping system 20 is arranged. The damping system 20 is attached to the connection system 10. The damping system 20 and the connection system 10 together form a (total) system 30 or a so-called free-flex system 30, which is set up to provide a gliding board with particularly free flex or particularly unhindered bending properties, and which is also particularly applicable effective way to ensure controllable driving characteristics. The connection system shown is optional.

The in Fig. 1 recognizable distance from mounting points to each other in the example shown is about as large as the sole of the ski boot 2, but is preferably chosen smaller, so that the one mounting point in the heel and the other mounting point in the bale area of a foot 2 held in the shoe is arranged ,

In the FIG. 2 an alpine ski 1 is shown, on which a base plate 12 of a connection system is mounted, wherein in different sections under the base plate 12, a first (front) push rod 24 and a second (rear) push rod 26 of a damping system are arranged. The push rods 24, 26 are each guided close to a corresponding free end of the alpine ski 1 and attached to the alpine ski 1 in the region of the free end. The alpine ski 1 extends along a longitudinal axis L corresponding to an x-direction of the indicated coordinate system. Further holes 26.2 or one or more slots are provided in the push rod, which can define certain positions of the push rod relative to the ski 1 for a hardness regulation of a damping system.

In the FIG. 3 For example, components of a connection system are shown in connection with components of a damping system. The connection system has a base plate 12 with a top 12a and a bottom interface 12b. From the base plate 12 are tabs 12.1, 12.2 down from, in particular two front tabs 12.1 and two rear tabs 12.2 (in the side view shown only one tab is visible), with the tabs 12.1, 12.2 each of a side surface 12c of the base plate 12 extend or are arranged as far as possible outside near to the corresponding side surface 12c. The respective front flap 12.1 has a bore or opening 12.1a. The respective rear flap 12.2 is part of a slotted guide with a contour 12.3, which has an elongated geometry. The contour 12.3 has an extent in the longitudinal direction, which is greater than a corresponding dimension of the opening 12.1a or as a corresponding dimension of the contour 12.3 in a height direction corresponding to a z-direction of the in FIG. 2 indicated coordinate system. The contour 12.3 is curved downwards in this embodiment, ie, viewed concave downwards from the top to the bottom. The contour 12.3 has, for example, a radius of curvature in the range of infinity (ie, the contour would be an at least approximately straight slot) to a minimum of about 10mm, 9mm, 8mm, or even 7mm, be it uniformly, be it in sections. As the radius of curvature becomes smaller, the change in height induced in the case of a translational relative movement becomes correspondingly greater. From this contour deviating contours are possible, in particular obliquely arranged, optionally curved slots, elliptical or only partially circular segment-shaped geometries.

The slotted guide can be formed alternatively by an arranged in a mounting plate contour and in the base plate, so separated from the mounting plate supported axis alternative to the embodiment shown (contour in base plate or tab and axle in mounting plate). For example, the mounting plate is in one piece and has an obliquely aligned and upwardly and / or downwardly curved contour. The mounting plate can be the only robust, solid part.

The base plate 12 can be mounted on the sliding board 1 by means of the mounting means 14, 16 shown. The mounting means 14, 16 are each formed here as a so-called rotary axis unit and each have a mounting plate 14.1, 16.1 and a bearing unit 14.2, 16.2, in particular bearing bush or bushing or bore, in which an axis of rotation or any bolt connection (each not shown) are stored can. The rotational axis or the bolt connection allows a relative rotational movement of the rotary axis units 14, 16 relative to the base plate 12. The rear rotary axis unit 16 may comprise a kind of roller system 15 or components of a roller mechanism, which is geometrically formed corresponding to the contour 12.3. The roller system 15 may comprise individual roller means with rollers or balls (not shown) which are adapted to be guided in the contour 12.3 and in the Contour 12.3 be moved between at least one front stop position and a rear stop position in a variety of different Fahrzustands- or control positions. Alternatively or additionally, a plain bearing may be provided.

The contour 12.3, the roller mechanism 15 and the corresponding parts of the corresponding mounting plate form a slotted guide K.

The respective rotary axis unit 14, 16 can be fixedly connected to the sliding board 1 in attachment points P. In contrast to the attachment points P, which do not allow relative movement, the openings 12.1a in the lugs 12.1 and the passages in the respective rotary axis unit respectively mounting points M, in which a mounting or storage can be made such that a relative rotational movement can be made possible ,

The respective rotary axis unit 14, 16 has a cavity 14.4, 16.4 for arranging a push rod, as in connection with FIG. 6 will be explained in more detail. The respective cavity 14.4, 16.4 is formed between two webs 14.5, 16.5 or support surfaces on which the bearing units 14.2, 16.2 are provided.

In the FIG. 3 is an axis of rotation or a pivot pin 14.3 indicated, which (r) in the respective opening or passage 12.1a, 14.2 can be arranged. Furthermore, an axis of rotation or a pivot pin 16.3 is indicated, which (r) can be arranged in the respective contour 12.3 or bushing 16.2, and which (r) can also be displaced in the longitudinal direction. The pivot pin moves during bending of the sliding board while in the slotted guide forward. In the arrangement shown, the pivot is in a maximum height position.

The respective axis of rotation or the respective pivot need not be provided over the entire width of the respective rotary axis unit 14, 16. Rather, it can for the purpose of a space-saving arrangement of in FIG. 6 be shown push rods expedient if the respective axis of rotation or the respective pivot is provided only in the region of the tabs, ie only laterally outside of the base plate or on the rotary axis unit.

The base plate 12 is coupled only in the two longitudinally spaced mounting points M or axes of rotation of the sliding board. Each mounting point can include one or more bushings or holes with the same longitudinal position.

Also indicated is a three-function damper 22 of a damping system, which will be described in more detail below. The three-function damper 22 may be coupled to the base 12 to form a free-flex system for providing a free-flexing sliding board with particularly good ride characteristics.

In the FIG. 3A a slot 12.3 is shown, which is arranged obliquely and is curved downwards. The slot 12.3 may also be formed in a straight line or at least partially curved upwards.

In the FIG. 4A a rotary axis unit 16 is shown in a plan view and in a side view, wherein the mounting plate 16.1, the respective bushing 16.2 with the respective pivot pin 16.3 arranged therein, the respective webs 16.5 and the cavities 16.4 formed thereby are shown. The rotary axis unit 16 has four attachment points P.

The FIG. 4B shows the base plate 12 in a rear view with the roller mechanism 15 and the two rear tabs 12.2 and a three-side view of the rear mounting plate 16.1 with the corresponding pivot 16.3. The corresponding pivot 16.3 can also be understood as a component of the roller mechanism 15. The diameter of the pivot pin 16.3 is formed corresponding to an inner diameter of a roller device 15.1 (in particular roller bearing) of the roller mechanism 15, so that the roller device can be arranged and fixed on the pivot pin 16.3, in particular without play, for example by a play-free fit.

In the FIG. 5 For example, components of a connection system are shown in connection with components of a damping system. The three-function damper 22 has a first (front) Dämpfungskavität (especially oil chamber) 22.1 and a second (rear) Dämpfungskavität (especially oil chamber) 22.2. Furthermore, the three-function damper 22 has a spring element 27 arranged between the damping cavities. At each free end of the spring element 27 engages in each case a piston rod 28d, to which a reciprocating piston 28.1, 28.2 is attached. The piston rod at the front and the piston rod at the rear both actuate the spring element 27. With flex on both sides of the front and rear sliding board, the spring element is compressed on both sides.

At the front side of the respective reciprocating piston 28.1, 28.2 a membrane 29.1, 29.2 is arranged. The membranes 29.1, 29.2 can be constructed the same. The front membrane 29.1 and the rear membrane 29.2 each have a centrally arranged passage 29b for the piston rod 28d and has a passage 29a, in particular a relatively small opening, for damped flow (in particular oil flow) of a damping medium. The passage 29a may be formed geometrically corresponding to a corresponding passage 28b in the corresponding reciprocating piston 28.1, which favors a precise setting. Depending on the damping medium, the passage preferably has a diameter of 0.1 mm to max. 1mm up. The passage can also be provided with a geometry deviating from the circular geometry, e.g. with elliptical geometry, in particular to be able to adjust especially fine when twisting in a certain way, especially fine.

The respective reciprocating piston 28, 28.1, 28.2 has a first passage 28a, in particular a (larger) bore, for undamped flow, and a second passage 28b, in particular a (smaller) bore, for damped flow. Furthermore, the respective reciprocating piston 28, 28.1, 28.2 has a passage 28c for the corresponding piston rod. A rotational position of the respective membrane may be e.g. be fixed by a thread is provided on the piston rod 28d and with a lock nut, the rotational position of the piston rod is fixed.

In the FIG. 6 For example, components of a connection system 10 in conjunction with components of a damping system 20 are shown. Corresponding components of the connection system 10 have already been described above. The damping system 20 has a front push rod 24 and a rear push rod 26, which are each connected to a corresponding piston rod of the three-function damper 22, namely in the coupling points 28.1a, 28.2a. The push rods 24, 26 extend below the base plate 12 and adjacent to or above the rotary axis units 14, 16 through corresponding cavities 14.4, 16.4 of the rotary axis units 14, 16. The respective push rod has thanks to the cavities sufficient space, especially in conjunction with rear pivot 16.3 and front pivot 14.3, which are each provided only in the region of webs 14.5, 16.5. In the event that the base plate is to be used without push rods or damping, alternatively, through-rotating axes front and rear can be used. In the figures, only one web 16.5 is indicated by a reference numeral, however, each rotational axis unit 14, 16 may comprise two pairs of webs.

In the FIG. 7 the ski 1 is shown in a folded state. The base plate 12 is substantially rigid and unbent, thus extending substantially in a plane independent of the bending of the ski 1. The three-function damper 22 has a first (front) damping element 23 and a second (rear) damping element 25 , By the flex, the base plate or the three-function damper 22 is lifted upwards and spaced from the ski 1. By increasing the distance with increasing bending, the effect (the lever arm) of the damping system 20 increases on the ski 1. The three-function damper 22 is fixed to the base plate 12. An attachment can be done for example by means of a clamp or a clamping strap, which is attached directly to the damper. Optionally, the damper can also be integrated in the base plate. An integration in the base plate has advantages in terms of space. The attachment can also be done by form and / or adhesion. The base plate may have a cavity for receiving the damper. An integrated damper can be protected against environmental influences.

In a variant in modification to the mounted on the ski 1 damping system 20, the damping system shown isolated on a setting option in the form of a threaded coupling. By means of the threaded coupling, the ski hardness can be adjusted manually in a simple manner, as described below. At least one of the piston rods 28d has a thread 28d.1, in particular an external thread at a free end. At least one of the push rods has a thread 24.1, in particular an internal thread at a free end. The thread 24.1 of the push rod 24 is formed geometrically corresponding to the thread 28d.1 of the piston rod 28d. The respective piston rod 28d can be screwed length variably into the internal thread 24.1 and positioned relative to the push rod. For example, the spring element 27 can be more compressed (compressed) by relative unscrewing, whereby a higher spring force is transmitted to the respective push rod 24, 26, so that the ski 1 harder and less flext. By means of the threaded coupling thus the hardness of the ski 1 can be adjusted via a bias of the spring element 27, in particular manually.

Furthermore, as in FIG. 2 shown, at least one of the push rods 24, 26 alternatively or additionally have a plurality of holes or a slot, in particular at a free (averted from the spring element) end, by means of which / which the push rod 24, 26 in different relative positions in the longitudinal direction relative to the sliding board on Gliding board is fixable, as in FIG. 2 shown. For example, three bores 26.2 are provided on the push rod 26, by means of which the position of the push rod can be adjusted relative to the ski 1, so that the bias of the spring element can be indirectly varied. On the ski 1, a corresponding coupling or any corresponding fastening means (not shown) is provided. The three holes 26.2 can also be a slot. A slot can ensure a continuous / continuous hardness adjustment. The length adjustment of the push rod allows, for example, to respond to a specific driver's weight. In other words, the ski hardness can be optionally set via at least two devices that are independent of each other. This adjustment provides great flexibility or variation.

In the FIG. 7 Furthermore, a positive locking element, in particular a raised portion, an adjusting pin or a locking projection 22.1a, 22.2a, is indicated on an end face of a respective damping cavity 22.1, 22.2. On a wall (damping wall) of the Dämpfungskavität (in particular of the damping cylinder) can thus be provided a survey or a paragraph or a protruding nose or a locking projection, which engages in retracted stroke piston in a passage or an opening of the membrane. The wall is preferably an end wall or an end face of the damping cavity. As a result, a respective damper can be determined or a damping function can be switched on or off.

In particular, it can be caused by a rotation of the piston rod or the damper by 180 ° that the damping characteristics are changed such that the damping of load-initiating damping in load-diverting reversal reverses, and vice versa. This is also possible in each case with respect to one of the push rods.

At the in FIG. 7 the embodiment shown, the respective membrane 29.1, 29.2 mounted on the respective piston rod 28d rotationally fixed via a positive connection or a fit. The reciprocating piston 28.1, 28.2 is not rotated during operation, but only pushed in and out, so that the membrane 29.1, 29.2 remains arranged at a constant rotational position. The respective membrane can be arranged depending on the desired damping characteristic, eg front. If the membrane 29.1, 29.2, as shown, arranged at a front side on the front of the reciprocating piston, the membrane during rebounding a relatively large passage (flow opening) 28a close / seal, as in FIG. 5 shown, so that a damping is particularly effective. During compression in the front, the membrane is opened by the flow of damping fluid, and the damping fluid can flow through the large passage 28a, so that no damping or only a much weaker damping is effected.

If, on the other hand, the diaphragm is arranged on the rear side of the corresponding reciprocating piston on a rear side, the diaphragm closes the large passage during compression in such a way that the damping is (especially) effective. When removing or extending the damper, the membrane then opens the large passage in the reciprocating piston, so that the damping is not effective. If a reverse damping characteristic is desired, it is possible to turn the damper by 180 °. The damping system can thus be adjusted and adjusted in a particularly simple and understandable manner for a driver, so that the driver can determine even his best setting, especially in racing. Factory settings are not required or can be changed. This can e.g. even with abruptly changing conditions such as be interested in a temperature drop.

In the Figures 8A, 8B . 8C, 8D a mounting plate 14.1 is shown, which has an obliquely arranged slot 12.3, which forms a slide guide K together with an axis 14.3 and a sliding element 15A. The mounting plate 14.1 can be made in one piece and made of a solid material. The sliding element 15A has a passage for the axle 14.3 and a shoulder which is formed between a side wall and a part which corresponds geometrically to the slot.
