CONNECTION SYSTEM FOR SLIDING BOARD

The invention relates to a connection system for a gliding board, in particular for a snow gliding board for skiing, with which a possible unhindered bending of the gliding board can be realized. In particular, the invention relates to a connection system according to the preamble of claim 1.

The invention also relates to a gliding board with a connection system between a binding and the gliding board and optionally also with a damping system. The connection system is preferably provided for snow gliders and adapted to secure a shoe on the snow glider, especially in alpine skiing, especially racing ski, in particular according to the World Cup safety standard (FIS Equipment Rules). The damping system is intended for the same type of snow gliders and suitable for damping and / or cushioning a relative movement. 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.

The invention also relates in particular to a system which allows the sliding board in the dynamic state to flex particularly well and unhindered. The system may include the damping system in addition to the connection system.

The patent DE 10 2012 206 881 B3 describes a device for connecting a base plate with 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.

In the prior art connection systems for sliding boards are described with a base plate which is fixedly mounted on the snow glider. If the sliding board loaded, it bends in the dynamic state when driving depending on the nature of the ground or depending on the driving style, but in the area of the fixed base plate bending is largely prevented so far. The present invention, in contrast, relates to a device or system which allows the gliding board to flex more freely even in the dynamic state than hitherto possible.

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.

The object is to provide a connection system optionally in conjunction with a damping system which can ensure the unhindered flexing of a sliding board when driving, especially in conjunction with a good controllability of the sliding board by a (ski) driver. In particular, the object can also be seen to conceive a system for a gliding board, in which unimpeded flexing also leads to an optimized handling behavior, in particular also to higher driving speeds in racing. Because the driving behavior is highly dependent on the flex characteristics of the gliding board, and the control of the gliding board should not be complicated by the fact that the gliding board can flex more freely. It is advantageous, in particular also 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 connection system can be easily adapted to a specific purpose or driver. Finally, a simple construction of the connection system or a high degree of robustness and thus load capacity is also advantageous.

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

A connection system for a gliding board, in particular for a snow gliding board for skiing, in this case 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 a lower interface to the gliding board wherein the base plate is connectable to the gliding board, the lower interface being adapted for predefinable relative movement between the base plate and the gliding board in response to or in response to flexing of the gliding board by relative rotation of the base plate about at least one mounting point on the gliding board.

According to the invention it is proposed that the lower interface for a height adjustment of a height position of the base plate is arranged in a height direction relative to the sliding board orthogonal to the longitudinal axis, wherein the base plate in at least one mounting point with the Schnittstellte is rotatably mounted on the sliding board and further along the longitudinal axis can be mounted displaceable relative to the sliding board by means of a gate guide provided on the interface or along a guideway, wherein the relative movement is defined by the slotted guide. 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 racing, the height of the stance with respect to the ski slope is limited to a maximum value under static conditions. The height adjustment according to the invention can cause a standing position above this maximum value in the dynamic state during driving and therefore makes it possible, for example. stronger cornering. 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 slide 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 can have at least two rigid rotary axis units, one of them (preferably the rear rotary axis unit) can compensate for any, also extending in the vertical direction backdrop or contour translational relative movement between the flexing sliding board and the fixed base plate. 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 elongated ski body and may further comprise an integrated in the base plate damping element front and another damping element for the rear part of the ski body with different characteristics. The damping system preferably has at least three functions.

In the prior art usually 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 covered by the binding part of the ski, usually about 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.

The present invention, however, allows a free dynamic flex of the snowboard over the entire length, regardless of how big / hard the ski boot or how long the binding plate 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 Schneegleitbrett over the entire length largely independent of a load condition flex freely and thereby also allows very good handling characteristics and improves the control of the sliding board. Also, the sliding board can work more flexible 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.

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 an attenuation or a damping system or cooperate therewith, as will be explained in more detail below. 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.

As a "sliding board" is preferably to be understood 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 a binding plate or a device to understand that is set to couple a binding or other device 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.

The term "slotted guide" 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 elongated hole is provided on a corresponding mounting plate or if a mounting plate forms part of the link guide, 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, the lower interface in addition to the height compensation of a relative height position of the base plate in a vertical direction orthogonal to the longitudinal axis and set up 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 an advantageous embodiment, the degree of height adjustment is coupled to a translational movement between the base plate and the sliding board, wherein the slotted guide is adapted to the height position as a function of the translational movement in sections or completely along the slotted guide in response to movement of the Sliding boards disproportionately, proportionally or disproportionately adjust. 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 a specific driver or conditions specific translational motion path. The dependence can be e.g. be proportional by means of a straight oblique contour, or over-proportional or underproportional by means of an obliquely arranged and additionally curved contour.

According to an advantageous embodiment, the lower interface is ausgebil-det such that the base plate in the direction of the longitudinal axis translationally mounted on the sliding board is 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 also 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 (slotted guide in the base plate). If the slotted guide is provided on / in the mounting plate, the axis of rotation shifts to the rear during flexing.

According to an advantageous embodiment, the lower interface for independently independent of the base plate dynamically freely adjustable bending line of the sliding board is arranged and connected to the sliding board so that the bending line can form 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 bevelled or chamfered.

Preferably, the lower interface is formed such that the shape of the base plate is independent of a bending of the sliding board in the region of the base plate is constant, in particular flat, with the sliding board can bend independently of a stiffness of the base plate or the ski boot. The bending line of the gliding board is not affected. The bending line can be adjusted largely independently of the stand weight or the forces exerted by the driver.

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

According to an advantageous embodiment, the base plate at the lower interface at a first (preferably front) mounting point is fixed relative to the sliding board on the sliding board rotatably storable and at a second (preferably rear) mounting point relative to the sliding board translationally displaceable, in particular axially displaceable in the longitudinal direction , storable on sliding board. 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 / flexing of the gliding board. In contrast, in the case of a lever mechanism as described in US Pat. No. 5,129,668 A, the base plate is greatly displaced during dynamic working of the sliding board, which results in a restless position and difficult control. Also, the weight of the driver counteracts a free Flexen.

Preferably, the connection system with the sliding board forms a multi-point storage, especially four-point storage, in which the base plate is connected only at individual mounting points with the sliding board relative to the sliding board displaced. The lower interface of the connection system preferably has a plurality of dynamic bearings for one bearing point each, in particular four dynamic bearings or sliding elements.

According to an advantageous 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 base plate. 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 an advantageous embodiment, the slotted guide has a contour, in which the height adjustment when bending the sliding board causes a rising with increasing bending height, in particular disproportionately or less than proportionally. 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 in the base plate or in a mounting plate.

According to an advantageous embodiment, the slide guide is arranged to assign at least a specific radius of a bending line of the sliding board a precise 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. The height position can be specified as a function of the radius of the bending line. It can e.g. can be adjusted so that from a certain amount of bending the height adjustment should only be quite moderate, or that up to a certain amount of bending the height adjustment should be relatively strong. This makes it possible, for example, to set for certain driving situations or driver weights how much the driver can get into the corner, that is, what inclinations of the driver in the curve are possible.

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.

According to an advantageous embodiment, the distance of two mounting points of the interface or axes of rotation on the sliding board in the longitudinal direction to each other is at most as large as or smaller than the length of a sole of a mountable on the base shoe. 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 a very good driving feel can be achieved if the force application points or mounting 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 an advantageous embodiment, a front and / or rear end of the base plate overlaps a front and / or rear mounting point on the gliding board, in particular by at least the simple or 1.5 times the length of a front binding coupling (binding head / bonding front jaws) and / or a rear binding coupling (binding car mat / binding backing), for example at least 10mm or 15mm. In this way it can be ensured that a pressure exerted by the bale or the heel of a foot of a driver can be transmitted as directly as possible to the sliding board. The overlap allows an advantageous arrangement of the mounting points and thus a good driving feel or a very direct feedback between foot and ground or slope.

According to an advantageous embodiment, a distance between the lower interface and the top 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 hindered by the base plate. 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 forwarding forces and shocks (three to five times the acceleration of gravity in jumps) rest 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, the lower interface of the base plate has at least one front and at least one rear tab or emphasis or guide on which a respective mounting point for the movable mounting of the base plate is arranged on the sliding board. The tabs can ensure a convenient arrangement of mounting points or axes of rotation. The tabs allow a distance between the base plate and the sliding board. The tabs allow for high robustness and can also ensure a smooth relative displacement of the base plate relative to the sliding board.

The tabs may be arranged laterally on the outside of the base plate and protrude from an underside of the base plate down. Preferably, two front and two rear tabs are provided, which are preferably comparatively far laterally arranged outside on the base plate. This can increase the stability of the assembly and / or control over the gliding board.

As an alternative to laterally arranged and downwardly projecting, in the width direction comparatively narrow tabs also highlighting or guides may be provided, which are integrated into the base plate, especially if a particularly robust storage of an axle or an enclosure of the axle is desired.

According to an advantageous embodiment, the slide guide, in particular a rear tab, a contour or recess or recess or backdrop, by means of which a form of movement or a movement path of a translational relative movement between the base plate and the sliding board for adjusting the height adjustment in Dependence of the bend is definable. 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 freely selectable. The height change may e.g. proportional to the change in length, or in sections disproportionately and / or disproportionately.

The movement path may 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 may have one or more forms 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 circle 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 upon flexing of the sliding board, the standing height of a driver between the base plate and the underside of the sliding board is increased. On 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 Flexsta-Dium only a small change in the height of the stand, and that the height of the stand then 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 the border area, the driver can be accelerated particularly well when cornering with high centrifugal forces, the height adjustment is stronger with increasing forces.

Alternatively, with an elliptical shape, the level can be changed so that in a first flex stage, a comparatively large change in the height of the stand, 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 the driving characteristics in the border area. At the same time, the driver's ski boot is already raised sharply even with small bends or even with relatively large bending radii, so that strong cornering situations can be achieved in many driving situations. This setting may e.g. Also be beneficial on a course, which is relatively slow, so in which experience is not particularly extreme centrifugal forces occur.

According to an advantageous embodiment, the slide guide on a extending in the vertical direction slot on which is curved for the height adjustment up or down and / or at least partially aligned rectilinearly obliquely to the base plate, or which has at least one radius of curvature and is curved to a arranged below the base plate or corresponding mounting plate center of curvature, 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 strong 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 an advantageous 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 be made, 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 may e.g. 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 sliding bearing or a corresponding sliding bush can e.g. be formed by a particularly smooth, low-friction material pairing, for example POM or PEEK. In this case, a contour can also form sliding edges or leading edges of the sliding bearing.

According to an advantageous embodiment, the roller mechanism to a roller device which is geometrically corresponding to the sliding 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 lower interface of the base plate is adapted to be attached directly to the sliding board. The connection system may comprise mounting means which are fixable on the sliding board and are adapted to fix the base plate to the sliding board. In other words, the attachment of the base plate does not necessarily take place by means of separate mounting means or Drehach units, but can also di rectly / directly done by means of the base plate, depending on the design of the sliding board.

According to an advantageous embodiment, the mounting means comprise a front rotary axis unit and a rear rotary axis unit, wherein each rotary axis unit has a bearing unit, in particular a passage or bore for a rotation axis or a pivot, wherein the front rotary axis unit preferably forms a pivot bearing together with the base plate , and / or wherein the rear pivot unit preferably together with the base plate forms an axial pivot bearing, which in addition to the relative rotational movement also ensures a translational relative movement axially in the longitudinal direction of the base plate relative to the sliding board and in the height direction.

Preferably, the rotary axis units are mounted on the sliding board and positioned relative to the base plate, that a respective axis of rotation in the region of a front and rear coupling of a binding for a ski boot is arranged. Preferably, the respective axis of rotation is arranged in each case at a rear or front end of a ski boot mounted on the binding or base plate, in particular also somewhat further inwards than the respective end. This arrangement of the rotational axis units relative to the base plate or to the ski boot provides the advantage that the load application exerted by the foot is in each case in the vicinity of the fulcrum. This ensures that the flex of the gliding board is close to the center of gravity of the (ski) driver. In other words, a bending line runs unge undermined also below the area in which the weight and centrifugal forces are transmitted by the driver on the sliding board. This results in a much shorter lever between a main force application point on the ground surface (especially the ski slope) and the center of gravity of the driver, whereby a good grip (a good "grip") of the sliding board can be ensured. As a result, the control of the sliding board can be simplified. It has also been shown that the closer this point is to the center of gravity, the lesser the likelihood that a skier's ligaments or tendons will be overburdened. In other words, the system according to the invention is particularly driver-friendly and physically less stressful than conventional systems and can optionally also provide a damping effect.

Preferably, the distance of the Drehachseinheiten in the longitudinal direction to each other is at most as large as or smaller than the length of a sole of a ski boot. This provides a good driving feel and an even less noticeable effect of the base plate on the bending line.

Preferably, the respective rotary axis unit has a mounting plate with a plurality of, in particular four, attachment points for fixed attachment of the rotary axis unit on the sliding board. Depending on the ski width, the attachment points are spaced apart by at least 35 mm in the width direction, and spaced apart from one another by at least about 70 mm in the direction of the longitudinal axis. The mounting plates can be as wide as possible in the width direction transverse to the longitudinal direction, in particular to allow a good edge grip. In the longitudinal direction, the mounting plates can be as short as possible, in particular so as not to affect the free flexing of the sliding board. Preferably, the mounting plates are shorter in the longitudinal direction than 80mm, 70mm, 60mm or even shorter than 50mm.

Preferably, the respective rotary axis unit on an axis of rotation or a pivot, which supports the base plate relatively rotatable to the rotational axis unit. In this case, a length compensation between the sliding board and the base plate in the bent or flexed state of the sliding board by a relative rotation on the axis of rotation of the rotary axis unit compensated, and also by a translational movement of the axis of rotation or one of the axes of rotation relative to the base plate.

According to a variant, the lower interface of the base plate overlaps the mounting means laterally outside and / or bounds this laterally outside. This also provides a good robustness.

According to another aspect of the present invention, the connection system also includes a damping system. According to an advantageous embodiment, the connection system comprises a damping system comprising: one or two dampers or damping elements, at least one push rod, and a spring element as part of the damper; wherein the damper or the damping system is formed as a three-function damper, which performs a spring functions and two separately realizable damping functions in the forward and backward direction, wherein the damping functions are preferably independent or adjustable ,

In other words, the height compensation can be used in conjunction with a damping system. A three-function damper can be integrated in the base plate or be connected to the base plate, wherein the three-function damper operates at least one push rod which can be axially fixed in the front and rear end of the snowboard. The three-function damper is designed to ensure the three functions of damping a bend in the front part of the sliding board, damping a bend in the rear part of the sliding board, and cushioning. The three-function damper preferably has one of the following or at least the following three components: a front damping element or a front Dämpfungskavität with reciprocating piston, a rear damping element or a rear Dämpfungskavität with reciprocating, 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 separate damping functions and a cushioning function.

In the prior art, however, dampers are found, which can attenuate particular load either introductory or Lastausleitend. On the other hand, the three-function damper according to the invention, on the other hand, can optionally dampen load-initiating and / or load-discharging. The three-function damper can be characterized by a diaphragm-controlled damping system. The damping system may be constructed based on different damping fluids. For example, the three-function damper can have as a Dämpfüngsfluid a gas, a gel, or oil, or other liquids.

The three-function damper preferably forms a functional element with the base plate. The three-function 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. The further aspect particularly relates to a damping system in which at least one push rod is movably mounted 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 in the longitudinal direction of the sliding board over any length of the rear sliding board movable is stored. The length of the respective push rod can be as large as possible, in particular at least approximately 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.

In the following, single preferred features of the three-function damper will be described.

The damping system preferably has a push rod attached to the rear and front end on the snow sliding board. The push rod is preferably coupled at one end with the three-function damper to the base plate.

According to a variant of the three-function damper is an oil damper, which is controllable via a diaphragm. The three-function damper is preferably connected to the front push rod in a load-unloading manner 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 fully utilized and not dampened to keep the gliding board fast. This has advantages especially in racing.

According to an advantageous embodiment, the three-function damper on at least one membrane and is controllable or adjustable by means of at least one membrane.

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 three-function damper.

Preferably, the three-function 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. When the reciprocating piston is moved towards the membrane side, the diaphragm can close 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 three-function 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 three-function damper is adjustable and adjustable, in particular manually or for or by the driver of the sliding board.

Preferably, the three-function damper on two independently working damping elements, in particular oil pressure damper, each with specific damping characteristics.

The three-function damper is preferably connected to the at least one push rod free of empty stroke, 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 stroke-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 for increasing the path lengths have been particularly long push rods or a lever mechanism, such as. from published patent application DE 199 40 182 A1. 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, "idle-lift-free" is to be understood as an attenuation in which instantaneous, i. Already at the smallest stroke, a damping effect can be achieved. 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 three-function damper is set up to be damped either only load-initiating or load-discharging, 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 three-function damper or by a 180 ° rotation of the reciprocating piston in conjunction with a membrane 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 three-function damper is, for example, connected to the rear push rod load-discharging empty-lift and has an undamped function, and / or load-discharging Leerhubfrei 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 three-function damper can be connected to either the load-initiating or load-discharging empty-lift-free with the front or rear push rod and have a muted function. Preferably, the damper is attenuated load derating.

According to an advantageous embodiment, the three-function damper on two reciprocating pistons, between which a / the spring element is arranged, by means of the spring element, the hardness or bending stiffness of Schneegleitbretts is manually adjustable, in particular by adjusting the relative position of the at least one Push rod in the longitudinal direction relative to the spring element.

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 in a simple way a tunability of the damping characteristic.

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

Preferably, the three-function damper is formed symmetrically at two free ends so that the three-function damper 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 reversed with the three-function damper reversed, ie the three-function damper can now be damped at the front and load-discharged undamped , In this way, the benefits of a load dissipating undamped arrangement can be used for a particular application.

Preferably, the three-function 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 three-function damper is adjustable, in particular by a membrane is positioned in a certain rotational position relative to the reciprocating piston such 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 comprises a valve control which is arranged to control the hardness of the three-function 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. The respective membrane can be arranged on the reciprocating piston, depending on the desired damping characteristic, e.g. front. If the diaphragm is arranged on the front side of the lifting piston on a front side, the diaphragm can close a comparatively large passage (flow opening) during rebound, so that damping is particularly effective. It adjusts itself load derating a comparatively strong damping. 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, so that no damping or only a much weaker damping is effected, as explained in detail with reference to Figure 7. It introduces load-inducing a comparatively weak damping (load-inducing undamped).

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

In other words, the hardness of the three-function damper is manually adjustable. The hardness can be adjusted by the driver himself. The driver is not limited to factory settings.

Preferably, the three-function damper is positively and non-positively connected to the base plate of the connection system. 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.

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

Preferably, the respective reciprocating piston on sealing means, in particular a fixed to an outer circumferential surface of the reciprocating piston, e.g. in a corresponding groove, arranged O-ring. In this way, a seal of a respective chamber of the damping medium or a compartment of the chamber of the damping medium can be made.

According to an advantageous embodiment, the three-function 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 the length of the push rods. Without idle stroke or thanks to greatly reduced idle stroke, a push rod can be kept shorter.

The aforementioned object is also achieved by a gliding board, in particular snow gliding board for skiing, with a connection system according to the invention. In this case, the connection system is 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 Schuhgrößen- or schuhärtenunabhängig. 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.

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

Slotted guide according to an embodiment of the invention.

In 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 damping shown is optionally provided.

The recognizable in Fig. 1 distance from mounting points in the illustrated example, although about the size of 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 a foot held in the shoe 2 is arranged.

In Figure 2, an alpine ski 1 is shown, on which a base plate 12 of a connec tion system is mounted, wherein a portion of 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.

FIG. 3 shows components of a connection system 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 (of which only one tab is visible in the side view shown), wherein the tabs 12.1, 12.2 each of a side surface 12c the base plate ^ extend or are arranged as far as possible close 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 coordinate system indicated in FIG. The contour 12.3 is curved downward in this embodiment, that is, concavely downwardly concave when viewed from top to bottom. The contour 12.3 has e.g. a radius of curvature in the range of infinity (i.e., the contour would then be an at least approximately straight slot) to a minimum of about 10mm, 9mm, 8mm, or even just 7mm, be it unitary, 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 may alternatively be formed by a arranged in a mounting plate contour and supported in the base plate axis to the embodiment shown (contour in base plate or tab and axis 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 via 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 a rotation axis 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) adapted to be guided in the contour 12.3 and in the contour 12.3 between at least one front stop position and one rear stop position in a plurality of different driving state or control positions to be relocated. 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 will be explained in more detail in connection with FIG. The respective cavity 14.4, 16.4 is formed between two webs or support surfaces on which the bearing units 14.2, 16.2 are provided.

In the figure 3, a rotation axis or a pivot pin 14.3 is 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 does not have to be provided over the entire width of the respective rotary axis unit 14, 16. Rather, it may be expedient for the purpose of a space-saving arrangement of the push rods shown in Figure 6, if the respective axis of rotation or the respective pivot is provided only in the region of the tabs, ie only laterally outside on the base plate or on the rotary axis unit.

The base plate 12 is coupled only in the two longitudinally spaced apart mounting points M or axes of rotation to 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 figure 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.

FIG. 4A shows a rotary axis unit 16 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.

Figure 4B shows the base plate 12 from 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 largely free from play, e.g. through a play-free fit.

FIG. 5 shows components of a connection system 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.

FIG. 6 shows components of a connection system 10 in conjunction with components of a damping system 20. 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 above 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 provided only in the area of webs 14.5, 16.5. In the event that only the base plate without push rods or damping is to be used, as an alternative, continuous rotary 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 each comprise two pairs of webs.

In the figure 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 may e.g. by means of a clamp or a clamping strap, which is attached directly to the three-function damper. Optionally, the three-function damper can also be integrated in the base plate.

In a variant in modification to the mounted on the ski 1 damping system 20, the damping system shown isolated on an adjustment 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. In the internal thread 24.1, the respective piston rod 28d screwed variable length 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 on the respective

Push rod 24, 26 is transmitted, 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 shown in Figure 2, 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 is fixable in different relative positions in the longitudinal direction relative to the sliding board on the sliding board, as shown in Figure 2. On the push rod 26 are e.g. three holes 26.2 provided 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 stepless hardening adjustment. The length adjustment of the push rod, for example, allows reacting to a particular rider weight.

In other words, the ski hardness can be optionally set via at least two means which are independent of each other. This adjustment provides great flexibility or variation.

In the figure 7 is also a survey, an adjusting pin or a locking projection 22.1a, 22.2a on an end face of a respective Dämpfungskavität 22.1, 22.2 indicated. 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, can be caused by a rotation of the piston rod or the three-function damper by 180 ° that the damping characteristics are changed such that the attenuation of load-initiating dampening in load-rejecting reversal reverses, and vice versa. This is then possible in each case with respect to one of the push rods.

In the embodiment shown in Figure 7, 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 position. The respective membrane can be arranged according to the damping characteristic, e.g. 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 rebound, a relatively large passage (flow opening) 28a, as shown in Figure 5, close, 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.

On the other hand, if the diaphragm (s) is arranged on the rear side of the corresponding reciprocating piston at 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 Figures 8A, 8B, 8C, 8D, a mounting plate 14.1 is shown, which has an obliquely arranged slot 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.
