Abstract

The invention relates to a snow-ski board, particularly a ski (1; 401), having a board body (2; 402) and a strap (3; 103; 403) supported and/or anchored on at least one support point (7; 407) on the board body. Said strap is guided in a longitudinally displaceable fashion in at least one control region (10; 410) and coupled to the snow-ski board relative to a longitudinal deflection in the control region such that a force along the strap resulting from a deflection in the snow-ski board acts on a guide region (12; 412) on a longitudinal end of the snow-ski board such that the snow-ski board is deflected in the guide region. Here, the snow-ski board has a transfer device (4) that transfers the force along the belt into the tensile force on the guide region. A force path between the board body and the guide region comprises the following elements in the following order: support point, strap, transfer device, guide region. The transfer device particularly includes an auxiliary strap (13.1; 13.2), wherein the auxiliary strap is disposed substantially in the longitudinal direction of the board body and cooperates with a guide region with a first longitudinal end such that, by the cooperation of the auxiliary strap and the strap, with the force along the strap the tensile force may be produced on the board body.

Description

SNOW BOARD WITH PULL-POWER TRANSMISSION DEVICE

Technical area

The invention relates to a snowboard, in particular a ski, with a board body and a belt, which is supported and / or anchored to at least one support point on the board body, wherein the belt longitudinally displaceable in at least one control area and coupled with respect to a longitudinal deflection in the control area with the snowboard is such that due to a deflection of the

Schneegleitbretts in the control area resulting force along the belt so on a

Steering area at one longitudinal end of the Schneegleitbretts acts that the Schneegleitbrett is deflected in the steering area. State of the art

Modern snow gliding boards such. As carving skis is based on the idea to achieve an improved cornering of the ski with a strong sidecut in a central region of the ski. For this purpose, the carving ski must be bent so that when tilted about a longitudinal axis of the ski, the waisted edge rests substantially over its entire length on the driving surface. Thus, a curve can ideally be driven along the edges, without the ski slipping off, that is, moved transversely to the edge longitudinal direction relative to a driving surface. The required deflection at a load in the middle ski area (weight of the skier, centrifugal force) is achieved in conventional carving skis by the snow resistance at the ski end areas. Here, on the one hand, the congestion resistance of the snow, on which the ski ascends, as well as the displacement resistance of the snow, which must be pushed to the side, comes to fruition. Thus, a greater force acts on the ski ends compared to a central region of the ski in order to achieve the desired deflection. Due to the increased load, it may be in the end regions of the ski pad z. B. to an undesirable slipping, oversteer or "eaten" or braking, whereby the cornering along the edges ("carving") is inhibited. In particular at competition rides such. As in slalom ski race is lost by the increased sliding resistance and by the "eating" valuable time.

Skis are known from the prior art, which have a top and bottom chord construction. Such sandwich constructions are known to have the goal of achieving a pressure distribution which is flat or even over the length of the ski at a central load in a region of the ski intended for the binding. With the usual sandwich construction, the flat pressure distribution is achieved only under static load or at best when driving straight ahead. As soon as cornering is initiated, the ski end regions are subjected to greater load in order to achieve flexing of the ski, which is required due to a sidecut of the ski for edge contact in the middle length range with the running underlay. The main points of stress between ski and driving surface are then at the ski end areas, ie the pressure distribution along the ski or the edges is no longer uniform or flat. In addition, various known alpine skis are trying to increase the pressure on the ski ends. For example, US 2004/0046362 (Rossignol) attempts to increase the pressure on ski end regions by applying a load of a ski binding mounted on a plate spaced from the ski body over rigid elements, e.g. B. push rods, is distributed to the end of the ski to increase the contact pressure there.

DE 199 17 992 A1 (Emig et al.) Describes an alpine ski, in which the carrying portion of the ski ends is increased by a belt system when loading a central region of the ski. The belt system of the ski essentially comprises a corrugated upper belt, in particular curved upwards in the binding region, and a lower belt connected at the end to the upper belt, the lower belt and the upper belt crossing over several times.

The increased stress in these known versions of the ski end regions has the disadvantage that the end regions dig deeper into the snow due to the greater load or "eat", resulting in an increased sliding resistance. In particular, the front end of the ski and the ski tip experiences a large traffic jam resistance through the snow to be displaced and slows down the ride.

A new approach is pursued by FR 2779658 (Salomon SA). This provides a arranged in a snow sliding tension belt, which is arranged in the longitudinal direction of the Schneegleitbresch slidably guided in this. The belt is fixed at its end portions to the snow sliding board, with one end attached above a neutral fiber and the other end below the neutral fiber at the snow slide board. If there is now a positive longitudinal deflection of the snow gliding board in the region of the belt in which it is guided below the neutral fiber, then a tensile force results along the belt, which raises or deflects the snow gliding board at the fastening of the belt above the neutral fiber. Thus, a front end portion of the Schneegleitbretts is bent at a deflection of the rear end portion and thus relieved. However, the tension belt according to FR 2779658 has the disadvantage that the tensile force in the belt or the displacement of the belt relative to the Snow gliding board is relatively small, which is why there is only a relatively small relief of the front end.

Presentation of the invention

The object of the invention is to provide a snow gliding board, in particular a ski, which belongs to the technical field mentioned at the outset and which avoids the problems of the prior art and in particular offers the possibility of improving the deflection behavior of a snow gliding board and dynamically adapting to the loads.

The solution of the problem is defined by the features of the first claim. According to the invention, a snow gliding board, in particular a ski, comprises a board body and a belt which is supported and / or anchored on at least one support point on the board body, wherein the belt is longitudinally displaceably guided in at least one control area and coupled with the snow gliding board with respect to a longitudinal deflection in the control area is. In this case acts due to a deflection of the Schneegleitbretts in the control area resulting force along the belt in such a way to a steering area at a longitudinal end of the Schneegleitbretts that the Schneegleitbrett is deflected in the steering area. The invention is characterized in that a transmission device is present, which transmits the force along the belt in the tensile force on the steering range.

In the following, the invention will be explained for simplicity with reference to an embodiment as a ski. The invention is therefore not limited to a ski, but can also generally with other snow gliding boards such. B. snowboards be an advantageous embodiment. "Ski" and "ski body" as well as "ski end area" etc. are used below without restriction of generality parts of the terms "snow sliding board", "board body", "board end area" etc. Furthermore, the terms "top" and "bottom" are used below, wherein a tread of the ski "down" on the ski or on a "bottom" of the ski is formed, and a side of the ski, which provided for the mounting of a binding is "up" on the ski or on a "top" of the ski lies. Likewise, "front" hereinafter refers to a direction or a region in a designated direction of travel, and accordingly "rear" denotes a direction or a region in the opposite direction. A "longitudinal deflection" of the ski hereinafter refers to a curvature of the ski in a plane which is perpendicular to a running surface of the ski and in which lies a longitudinal axis of the ski. In this case, the ski is curved such that the projection of the longitudinal axis on the tread is also in the bent state of the ski in this plane. In the following, a "longitudinal deflection" synonymously also simply referred to as "deflection". A "positive flex" of the ski or longitudinal portions of the ski then refers to a longitudinal deflection of the ski in which the ski ends are curved upwardly away from a pad, ie, in other words, where the tread is (Lower chord) of the ski stretched and the top of the ski (top chord) are compressed.

The ski body of a ski according to the invention with a transmission device may comprise a ski body known from the prior art, such as, for example, a ski body. B. an aforementioned ski body with a top and bottom chord construction. Transfer device and belt are but largely integrated with advantage in the ski or in the ski body. Instead of increasing the load on the ski ends, in skis with dynamic belt systems of the type according to the invention, a ski area or a steering area of the ski is actively lifted or relieved away from a driving surface when cornering is initiated. The lifting takes place as a result of a deflection in a control area of the ski. This results in a dynamic and active steering of the ski into cornering. Skis with dynamic belt systems are thus characterized by a significantly improved smoothness and cornering when compared to "passive" or static skis. In particular, it is achieved that even when cornering when the ski z. B. is bent due to a sidecut by the central load by the skier, a substantially flat pressure distribution is maintained. Likewise, vibrations and negative deflections ("negative flex") z. B. are damped as a result of shocks by the driving surface or the ski through such belt systems and the acting tensile force on the steering range. The invention is now based on the idea to better utilize a displacement of the belt in the control area relative to the ski body or a resulting force along the belt for the dynamic steering of the ski. In addition, the inventive transmission device allows a more versatile construction of a dynamic steering ski, whereby the ski can be better adapted to the respective needs and needs.

In contrast to known skis with dynamic straps, a ski according to the invention for this purpose has an additional Clbertragungsvorrichtung which transmits a force in or along the belt in a tensile force on the steering range. In particular, the transmission device transmits the force along the belt, which results from a deflection of the ski in the control area, in a tensile force on the steering area. The traction engages in such a way in a steering range at a longitudinal end of the ski on the ski body that the snow sliding is deflected in the steering area. In particular, several z. B. substantially parallel straps on the ski be present, which can exert a tensile force on a steering range via one or more transmission devices.

For the purposes of the invention, additional elements on the ski are understood to mean a force in the belt z. B. deflected, increased or decreased in terms of amount, but also transferred at the same amount shifted parallel to the steering range. For this purpose, transmission devices according to the invention comprise, for example, lever elements mounted fixedly on the ski, lever elements pivotally mounted on the ski, or general joints or even gears and deflection rollers. In particular, the transmission device may also include auxiliary straps, which, for example, remove the force along the belt and transmit it to the steering area or to further elements of the transmission device. But auxiliary straps can also transmit a force from other elements of the transmission device to the steering area without interacting directly with the straps. In general, the auxiliary straps alone or together with other elements of the transmission device cause a Kraftüber- or force reduction and / or a deflection of the force. For the purposes of the invention, a transmission device is thus to be understood as an apparatus which allows a power transmission between the belt and steering range, which goes beyond the known interaction of a belt with the ski body and / or the ski. In particular, a simple attachment of a belt such. B. a screw with which the belt is screwed to the ski body, no transmission device in the context of the invention.

According to the invention, the transmission device can transmit at least one positive deflection in the control region to the steering region. But it can also be provided that the transmission device and a negative curvature in the control area z. B. transmits in the same direction to the steering range. In other words, with a ski according to the invention with the transmission device as a result of a longitudinal deflection of the ski with a positive or negative curvature in the control area, a curved longitudinal deflection of the ski in the steering area can be generated in the same direction. The coupling of the control area with the steering area via the transmission device in this case is a forced coupling, which transmits a deflection in one of the areas (control / steering) to the other area. However, it is also conceivable that the coupling is not a forced coupling and the transmission device can indeed transmit a deflection in the control area to the steering area, but a deflection in the steering area is not transmitted to the control area. In other words, in the case of a ski according to the invention, the transmission device can thus only permit the generation of a positive longitudinal deflection of the ski in the steering region as a consequence of a positive longitudinal deflection of the ski in the control region.

A displacement of the belt relative to the ski body in a longitudinal deflection is achieved when the belt outside, ie above or below a neutral fiber of the ski body is guided on or in the ski body. With the achieved by the bending displacement of the belt can be transmitted in the direction of displacement along the belt, supported or anchored to the support point on the ski body, a force between the ski body and belt. According to the invention, due to the transfer device, the force in the belt at a positive deflection of the ski in the control area be both a tensile and a compressive force, ie the belt can be both a compression belt and a tension belt.

In contrast to known skis comprises a possible embodiment of a ski according to the invention z. B. also provided on the top of the ski, structurally simple pressure belt. The resulting due to a positive longitudinal deflection compressive force along the pressure belt can be transferred according to the invention with the transmission device in a tensile force on the steering range. With particular advantage, in such embodiments, the pressure belt and the transmission device can be formed integrally on a ski top, where they z. B. are easily accessible for maintenance and, for example, not restrict an embodiment of the tread of the ski. By the transmission device is thus achieved that a ski according to the invention can be adapted in a more versatile manner to the respective requirements.

In the following, various terms used in the present text are explained.

The steering region denotes a longitudinal region of the ski in which a deflection is obtained as a result of the tensile force transmitted by the transmission device or in which the tensile force acts. The steering range is thereby deflected without or with reduced, support / pressure force by the driving underlay or snow resistance, due to the tensile force that acts essentially over the entire length of the tread substantially uniform pressure of the edges on the driving surface. In particular, cornering along the edges is possible substantially without overpressure on the steering range (s) in the one or more end regions of the ski. The bending of the ski required in modern garving skis is thus dynamically supported or dynamically predetermined in the ski end regions by the belt and the transmission device according to the invention. The ski steers, depending on the deflection in the control area, z. B. the front ends of the ski in the curve. This significantly simplifies cornering. The necessary for the "carving" (cornering along the waisted edge) deflection of the ski is no longer as in conventional skis alone by supporting the Skiendbereiche on the driving surface but the ski bends or bends dynamically in the steering range under load in the control area.

In a preferred embodiment of a ski, the steering area lies in an area at the front longitudinal end of the ski, i. H. in a front end region in the direction of travel. Depending on the load or deflection in the control region of the ski can thus be dynamically generated a corresponding curvature in a front region of the ski. The steering range of the ski can also be formed in a rear end region. In particular, a steering region can also be formed on both longitudinal ends of the ski, which may be a preferred embodiment, especially in modern freestyle skis or snowboards. Such skis or boards are bent at both longitudinal ends and also allow a reverse drive or in the case of snowboards both longitudinal ends can show largely equal in the direction of travel. A steering range at both ends thus allows to take advantage of a dynamic belt system in any current direction of travel. In this case, for example, in each case one belt act on the associated steering area via a respectively associated transmission device. However, it is also conceivable for a single belt to operate both steering areas via a single transmission device. While such designs may thus be quite preferred variants, however, they require a significantly greater design effort than an embodiment of the ski with only one steering range.

With control area a length range of the ski is designated, in which the belt is guided relative to the board body largely displaceable in the longitudinal direction of the ski. In the control area a deflection of the ski is "felt", whereas in the steering area a deflection is produced as a function of the deflection in the control area The control region also advantageously includes an end region of the ski, which lies opposite the steering region in particular, and is advantageous in that, when one is used to displace the snow, the control region also advantageously comprises the skier or the additionally acting centrifugal forces that occur during cornering required heel pressure is facilitated by the skier turning into a curve. Due to the heel pressure bends against the resistance of the snow to be pushed aside the rear ski area. This deflection is then transmitted to the front steering area and the ski steers dynamically into the curve. On the one hand, the front ends of the ski are relieved of load, that is to say their carrying portion is reduced, and, on the other hand, the front ends of the ski are deflected so that the edges of the ski rest evenly on the driving surface and support driving along the waisted edges ("carven").

It is also conceivable that the control region comprises a front end region and a central region and the rear end region is acted upon by the tensile force and forms the steering region. This is z. B. achieved that at a deflection of the front region, as z. B. may occur due to the congestion snow resistance when turning in a cornering, the rear area of the ski is also curved and thus can be easily tracked around the curve. The ski reacts in this case to the load of the front ski ends with a simplification of the cornering behavior

Deflection of the rear ends of the ski (rear steering area).

The deflection of the ski in the control area is "felt" by the belt by being displaced due to the deflection relative to the ski body. For this purpose, the belt is guided in the longitudinal direction displaceable in the control area and is anchored or supported by a support point on the ski body. The control area advantageously adjoins the support point in order to achieve optimal utilization of the available length range in which the belt is displaceably guided. In principle, the control region can also be arranged at a distance from the support point.

As possible longitudinal guides here are all known straight or possibly bow guides in question, which are basically suitable for use in a snowboard or ski. Conceivable z. B. in the case of as

Push rod belt formed a training of slots on the belt through which the belt with screws or bolts z._B. anchored in the ski body, am

Ski body is guided. Also conceivable is an embodiment of the guide as a conventional groove in the ski body, in which the belt is slidably disposed. In this case, the leadership z. B. be designed as a dovetail guide, wherein the belt forms a sled of leadership. The belt can be configured in the case of a tension belt but also as a cable or band and z. B. in a suitably trained z. B. pipe-like sheath be performed (eg Bowden train). Regardless of the specific embodiment, the guide has to ensure that the belt essentially, ie in the context of manufacturing or management tolerances, is displaceably guided in a longitudinal deflection with substantially only one degree of freedom relative to the ski body.

In other words, the guide is designed such that, at least in the control area, there is a coupling of the ski body to the belt with respect to a positive longitudinal deflection of the ski. In particular, the coupling can also be a forced coupling. The belt then experiences in a longitudinal deflection also a deflection, which essentially corresponds to the deflection of the ski body. The two deflections may differ within the scope of guide tolerances and / or distance from a center of curvature. Preferably, the belt is centrally guided d. H. the belt is arranged substantially centrally of the ski with respect to a direction transverse to the longitudinal direction of the ski. However, embodiments of the ski are also conceivable in which a laterally offset guide is preferred. It can z. B. several straps with respect to a plane which is perpendicular to a ski surface and includes the longitudinal direction of the ski, laterally offset and arranged substantially symmetrically on the ski.

However, the guidance of the belt can also deviate in regions from the longitudinal direction. It may well be desirable or necessary that the belt z. B. at a remote from the support point longitudinal end, z. B. in a direction transverse to or against the longitudinal direction, is deflected or deflected (eg., In the case of a flexible push rod) or deviates in different longitudinal ranges to different degrees of a longitudinal direction.

The above-mentioned support point can be anchored in the ski body with z. As a screw or a bolt or even an adhesive area in which the belt is glued to the ski body. It is also conceivable that the belt at the support point, z. B. on the ski body, is formed. However, the support point does not need to be fixed relative to the ski body, but can also be adjusted z. B. be designed to be displaceable in the longitudinal direction. In order to be able to transmit the deflection by the displacement of the belt easier or to achieve the greatest possible effect, the greatest possible displacement of the belt with respect to the ski body is desirable for a given deflection of the ski in the control area. Therefore, the control area is preferably formed as long as possible or required on the ski. In order to achieve a good utilization of the longitudinal deflection, the support point lies in a preferred embodiment in an end region of the ski, which lies opposite the steering region. In general, the support point is preferably arranged in a rear end region of the ski. In particular, in the case of a ski according to the invention with a belt designed as a compression belt, a support point can preferably also be arranged in a front region of the ski, preferably in the steering region. In this case, the control region extends, for example, from the steering region, ie, from the longitudinal position of the support point to the rear. A freely displaceable longitudinal end of the pressure belt is then arranged, for example, at the rear end of the ski. With the transfer device according to the invention, the force which can be removed at the free end of the belt can be transmitted along the belt back to the steering area in the front ski area, in particular, for example, with an auxiliary belt.

In order to maximize the length range of the ski covered by the control area, the control area and the steering area may also overlap to a substantially arbitrary extent. In particular, embodiments are also conceivable, which have a control area which comprises substantially the entire length of the ski, wherein the steering range z. B. can form a portion of the control area. The length ratios between the control area and the steering area as well as between the total length of the ski and the steering or steering area are basically freely selectable and can be adapted to the requirements of the ski freely. In particular, it is also conceivable that the steering area extends substantially over the entire length of the ski.

The invention is not limited to an end-side arrangement of the support point. It is quite possible that a z. B. in the longitudinal center arrangement of the support point for a ski can be beneficial. The belt can then z. B. extending from the longitudinal center of the ski in a control area in a direction forward or backward. It can then z. B. connect two control areas to the support point, with respect to the Support point forward and a back control area. Supported or anchored to the central support point can then be generated in the belt due to a deflection of the ski in the control areas in the middle region on both sides of the support point along the belt force which can be transmitted as tensile forces on corresponding steering areas at the ski ends. But it is also conceivable, for. B. use two straps each other. One of the straps then has z. B. has a rear control area and acts on a front steering area and the second belt has a front control area and acts on a rear steering area.

A ski according to the invention is not restricted to designs with only one transmission device and / or only one belt. In the following, the invention is described for the sake of simplicity, unless otherwise stated, as an embodiment with only one belt and an associated transmission device. Without limitation, however, any number of straps and associated transmission devices may be present. In particular, several, essentially parallel guided belts may be present on the ski. The individual straps can in this case z. B. slimmer and / or lighter dimensions. The effects of each belt can be z. B. add to a common tensile force on the steering range. In this case, z. B. only one transmission device is present, which transmits the forces of several straps in a common tensile force on the steering range. But it is also conceivable that the individual belts act with different tensile forces on different areas of a single steering range. This can z. B. the deflection of the steering area in different lengths individually controlled. In addition to the deflection but also a distortion of the ski can be generated by different tensile forces attack in different width sections of the steering range or a direction of the tensile force not in the longitudinal direction but obliquely to this points. In this case, for example, each belt can be assigned a transmission device which transmits the force along the belt to the respective area in the steering area.

In addition, several steering areas may be present on the ski, z. B. at both longitudinal ends of the ski each have a steering range. In principle, it is also conceivable that only one belt is present and the inventive transmission device transmits the force along the belt in a plurality of tensile forces, which engage at different positions in the steering range or in several steering areas.

The longitudinal position at which the tensile force acts can be adapted to the requirements. The tensile force preferably engages the ski body from above, d. H. from a direction above the ski body or from a direction from above, in the ski body. One

Force vector of the tensile force thus shows, starting from the area in which the tensile force on

Ski body attacks, out of the ski in an upward direction or has one

Force component which is perpendicular to the ski body at the point of application. This ensures that the steering range is deflected in a positive sense, causing the ski in the

Steering is lifted from a driving surface.

The tensile force, which acts on the steering area of the ski, is a result of an interaction of the ski body or the ski with the longitudinally displaceable guided belt. In particular, a force action between the ski body and the steering area during deflection of the ski in the control area passes through the following elements in the order indicated: support point, belt, transmission device, steering area on the ski body. The list of enumerated elements of the force path is not exhaustive and it may be the intermediate elements enumerated more elements and / or arranged end of the force path. In particular, z. B. between transfer device and steering area further elements may be arranged, which affect the effect of the tensile force z. B. translate amount and / or redirect in a desired direction. Here, further support points on the ski body are conceivable, on which the tensile force is partially supported or is further deflected. In particular, it is z. B. conceivable that on the ski body, a support element is formed or mounted, on which the transmission device engages with the tensile force. This can z. B. an improved according to the requirements of the traction angle, that is, an improved angle of attack of the tensile force on the ski body, can be achieved.

In a preferred embodiment, the transfer device of the ski comprises at least one auxiliary belt. The auxiliary belt is arranged substantially in the longitudinal direction of the ski body and acts, in particular with at least one first longitudinal end, together with the steering area. In particular, the auxiliary belt cooperates with the steering area in such a way that a tensile force generated in the auxiliary belt acts on the ski body in the steering area. The auxiliary belt and the belt cooperate in such a way that the force acting on the steering area in the auxiliary belt can be generated with the force along the belt. The auxiliary belt can act directly on the ski body or interact via deflecting, transmission or support elements with the ski body or the ski in the steering area. A bias of the auxiliary belt is not required, but may form a preferred embodiment as required. The auxiliary belt can z. B. to be biased to a predetermined voltage or the bias is adjustable by the skier. Thus, the deflection behavior of the ski in the steering range z. B. personal needs of the skier and / or adapted to the current snow and slope conditions. While basically no bias in the auxiliary belt is required, at least one embodiment is preferred in which the auxiliary belt has no play, that is substantially taut. Thus, a tensile force is transmitted to the steering range even with small deflections.

The setting of a bias in the auxiliary belt or else, in the case of a belt designed as a tension belt, a bias in the belt itself can be made by conventional tensioning devices in the belt or in the auxiliary belt. It is the application of so-called belt tensioners conceivable, which are provided on the belt itself. But it is also conceivable to generate the bias by a shift or adjustability of the longitudinal position of the support point. By shifting the support point relative to the ski body can, for. B. be adjusted directly in the belt tension or indirectly a tension in the auxiliary belt to be changed. The default of the voltage can z. B. be made by the skier before the start of the ride. In a preferred embodiment, the auxiliary belt is connected to the belt with a second longitudinal end. With a second longitudinal end, a longitudinal end of the auxiliary belt is designated in this case, which does not attack the steering area of the board body, but loves this longitudinal end opposite. By connecting the second longitudinal end of the auxiliary belt to the belt, a displacement or force can be transmitted directly to the auxiliary belt. In particular, the second longitudinal end of the auxiliary belt is connected to a free longitudinal end of the belt, ie with a longitudinal end of the belt, which faces away from the support point. Thus, the displacement of the belt, which occurs at the free longitudinal end, are transmitted directly to the auxiliary belt. The auxiliary belt can be attached to the belt or be integrally formed on this or be connected to it in a different way. Such an embodiment is particularly preferred in the case of a ski according to the invention, in which the belt is a pressure belt which can be subjected to pressure substantially, and the auxiliary belt is a tension belt which can be loaded to a substantial extent on tension. A compressive force along the belt can thus be transferred in a simple manner in a tensile force in the auxiliary belt with appropriate guidance of the auxiliary belt, which then acts on the steering area of the board body over the first longitudinal end of the auxiliary belt.

In a further preferred embodiment, the auxiliary belt is also anchored to the ski body with a second longitudinal end. In particular, the auxiliary belt is taut or biased z. B. in the sense of a chord, so that a deflection substantially transverse to the auxiliary belt can generate the tensile force on the steering area. In this case, the auxiliary belt may be formed in particular with adjustable bias. The bias can be z. B. be regulated or presettable by the skier. Depending on the strength of the deflection transversely to the auxiliary belt, a tensile force in the auxiliary belt can be generated, which acts on the anchorages of the longitudinal ends of the auxiliary belt in the ski body, on the ski body and in particular on the steering area. In this case, the steering region is bent in particular between the two longitudinal longitudinal positions of the anchorages of the longitudinal ends of the auxiliary belt.

However, another embodiment is conceivable in which the second longitudinal end of the auxiliary belt is also anchored to the same longitudinal position as the first longitudinal end. The auxiliary belt then forms a loop. The loop can in this case z. B. be guided around pulleys in a rear end region of the steering area and there cooperate with the belt of the ski so that due to a force in the belt, a tensile force on the two anchored longitudinal ends towards the rear end of the ski results.

In principle, other variants are conceivable in which the auxiliary belt z. B. is connected to both longitudinal ends of the belt and due to a force along the belt of the auxiliary belt, for example, a provided on the board body in the steering area element with a tensile force applied. In principle, however, embodiments of the transfer device are preferred in which the auxiliary belt with a, ie the first, longitudinal end acts directly or indirectly on the steering area, since thus an additional z. B. deflection is not required. In a particularly preferred embodiment, the transmission device according to the invention has additional transmission elements, which are provided movably or rigidly on the board body, wherein the tensile force on the steering area of the board body can be generated by interaction of the transmission elements and the belt with the force along the belt. The transmission elements can, for. B. closing a force path between the belt and the auxiliary belt and / or the guide z. B. redirect the auxiliary belt or transmit forces or moments moderately. The transmission elements, the belt and in particular also the auxiliary belt interact in such a way that the force acting on the steering region in the auxiliary belt can be generated with the force along the belt. Since the force along the belt results from a displacement of the belt relative to the ski body, it is generally advantageous to arrange the transmission device in a stationary manner with respect to the ski body, in particular to fasten it to the ski body. Depending on the design of the transfer device this z. B. attached as an additional device on the ski body or can also be formed directly on the ski body or configured. Due to the fixed attachment of the transmission device on the ski, the transmission device is supported on the ski and the force along the belt is without z. B. transfer of the transmission device with respect to the ski body in the tensile force transmitted to the steering area. With a fixed arrangement of the transfer device relative to the board body can be connected a comparatively simple construction. However, it is quite conceivable that in certain variants of the invention, the transmission device is advantageously formed partially or completely relative to the ski body displaced. In particular, deflection rollers are conceivable, for example, which are firmly connected to the belt and are moved with this relative to the ski body. These can cooperate in this case, for example, with an auxiliary belt, which is anchored to the ski body. Which of the execution options here depends on the actual implementation of the invention and is at the discretion of the expert.

Advantageously, the transmission elements comprise a lever element, on which the force engages directly or indirectly along the belt and which firmly, in particular under a largely fixed alignment with the board body, is connected to the board body.

It is thereby achieved that with a force acting on the lever element in the longitudinal direction of the ski, a torque can be generated on the board body with respect to a transverse axis, which at a sufficiently large amount the steering range of the ski of a

To take out a document, d. H. generates a longitudinal deflection in the steering area. The torque results in particular because of the lever element on the

Board body transmitted traction.

In particular, while a lever-like element is conceivable, which is connected at a substantially fixed angle to the ski body to a base of the lever member in the steering area fixed to the ski body or attached thereto. In this case, if the tensile force acts on the lever at a certain distance from the base (and thus from the board body or from a surface of the board body), then a torque is applied to the ski body with respect to the base. Due to the torque on the ski body is bent due to the flexibility of the ski body this. Due to the rigidity of the ski body, the pivot point is not exactly defined and can shift in the pulling direction, in particular as a function of the instantaneous deflection of the steering area.

Particularly preferred is an embodiment of the lever member, which extends substantially parallel to a surface of the board body and spaced therefrom toward a rear end of the Schneegleitbretts, wherein the lever element has a free end. The free end is preferably facing the rear end of the ski, in particular facing that end of the ski, which faces away from the steering area. With such a lifting element, a comparatively large leverage can be achieved with a small height. Namely, by the lifting member being fixed to a base on the board body and extending rearwardly from the board surface largely parallel to the ski, a can comparatively long lever arm with a correspondingly large leverage on the ski surface can be arranged. If a force now acts on the free end of the lever arm towards the top of the board, this results in a large torque at the base, which acts on the steering area of the ski and bends it. The overall height corresponds largely only one thickness of the lever member plus the distance of the lever arm of the board top. The lever arm preferably has a high rigidity, so that the force effect on the free end with the highest possible efficiency is transmitted to the ski body. When using modern materials such. B. composite materials, the lever arm can be made very thin with great rigidity, which overall a comparatively small, largely independent of the length of the lever arm acting, height can be achieved. The effective lever arm is given in this embodiment substantially by the length of the free end of the lever arm. The lever element can but in a variant also z. B. are perpendicular to the ski surface. Although this also allows a good leverage achieve, the entire height is given in this case by the acting lever arm, which would lead to awkward and excessive construction from a certain lever arm length.

In particular, embodiments are also conceivable which have a plurality of lever elements, which are operated by respectively associated (auxiliary) straps. In a modification, the plurality of lever elements may be arranged at different longitudinal positions, so that the generated longitudinal deflection in the steering region can be controlled as a function of the longitudinal position. However, the plurality of lever elements can also be distributed only or additionally transversely to the longitudinal direction of the ski, whereby a twisting of the ski can be generated. In a further preferred embodiment, the transmission elements deflecting elements for deflecting a force effect. In particular, the deflecting elements may comprise deflection rollers around which, in particular, the auxiliary belt is guided in regions. But the pulleys can also lead, for example, trained as Zuggurt belt and deflecting. Preferably, the pulleys are rotatably mounted about vertical axes of rotation on the ski body. In particular, for example, two Umienkrollen present, which on both sides of a centrally attached to the ski body belt attached to the ski body. The auxiliary belt acts in such a way with the belt, that with a displacement of the belt relative to the ski body, a portion of the auxiliary belt is taken from the belt. For this purpose, a driver, z. B. a further deflection roller, be present, which entrains the auxiliary belt during a displacement of the belt. The auxiliary belt can also be anchored to the belt and thereby be taken with a shift. Here, also several auxiliary straps may be present, which z. B. are anchored with one longitudinal end in the steering area on the ski body and with the other longitudinal end of the belt. By a suitable arrangement of the pulleys on the ski body and corresponding areawise guidance of the auxiliary belt around the pulleys, it is ensured that a tensile force acts on the steering area when the belt is displaced relative to the ski body at the end of the auxiliary belt or auxiliary belts anchored to the steering area.

If the belt is a pressure belt which can be subjected to pressure, the tensile force on the steering region is achieved, in particular, by a compressive force in the pressure belt acting on the auxiliary belt in a forward direction via the driver or via the anchoring of the auxiliary belt to the pressure belt. By the pulleys, the forward pressure on the auxiliary belt is deflected in a tensile force along the auxiliary belt, which acts as a tensile force at the anchored longitudinal end of the auxiliary belt substantially in one direction to a rear end of the ski. The tensile force acts in particular between the anchored in the ski body longitudinal end of the auxiliary belt and the attachment of the deflection, z. B. the pulleys on the ski body. In particular, defines the area between the anchored longitudinal end of the auxiliary belt and the attachment of the pulleys on the ski body the steering range of the ski, d. H. the longitudinal area of the ski, which is deflected due to the tensile force.

Likewise, however, it is also conceivable that a tensile belt which can be loaded on a train acts on the steering region of the ski via an auxiliary belt deflected by deflecting rollers with the tensile force. Instead of pulleys, the deflection can also be achieved by other elements. In principle, any suitable device for a deflection or any suitable element can be used. It can z. B. directly on the ski body or on the pressure belt pins or notched projections be formed or attached. Of the Auxiliary belt and / or trained for example as a tension belt belt is then z. B. led around this deflection forming pin or projections. In this case, the auxiliary belt or belt is preferably guided displaceably around the deflecting elements, ie with slippage.

The tractive force or the traction path can be substantially the same in terms of magnitude as the force or the displacement in the belt. However, if a Kraftüber- or -Üntersetzung desired, the Umienkrollen can in particular be mounted eccentrically, so that there is a different leverage with respect to the axis of rotation depending on the point of the auxiliary belt on the pulley.

Preferably, the transmission elements of the transmission device comprise an adjustable, in particular height-adjustable support element, which is adjustable by the force along the belt or a displacement of the belt. An adjustable support element is preferably used in an embodiment in which an auxiliary belt is anchored to the ski body with both longitudinal ends in the sense of a chord in the steering area. An adjustable support member may also be present as straps designed as tension straps as an additional, the tensile force enhancing element, which is adjusted for example via an additional belt present on the ski. In the following, the support element will be described with reference to the example of an auxiliary belt anchored to both longitudinal ends on the board body.

The auxiliary belt is largely taut, so that a deflection substantially transversely to the auxiliary belt can generate a tensile force along the Hilfsgurts. The adjustable support element is supported on the auxiliary belt such that it deflects the auxiliary belt transversely to a longitudinal direction of the auxiliary belt during adjustment. In this case, the support element may be supported on the ski body. An advantage of a support on the ski body is z. B. in a controllability or fixability of the bending center of the deflection. Depending on where the support element is supported on the ski body, the deflection, in particular the shape of the deflection, can be controlled. It is Z. B. possible that at the location of the support of the support element on the ski body z. B. a minimum radius of curvature of the deflection, ie a maximum deflection, is generated. In this case, the support element preferably comprises a lever, which is pivotable about a transverse axis and pivotable on the board body, which lever the force along the belt or due to a displacement of a free end of the belt can be pivoted and cooperates with the auxiliary belt, that the force along the belt, in particular via the adjustment of the support element, causes a deflection of the auxiliary belt transversely to a longitudinal direction of the auxiliary belt , The auxiliary belt may be formed as a substantially pure tension belt, but may also have a certain inherent rigidity, for example in the sense of a flexible rod. This results in a deflection of the auxiliary belt transverse to the longitudinal direction due to the stiffness, the force component at the ends, in particular on the anchoring points of Hilfsgurts in the board body, can increase in deflection, ie a tensile force is provided at the longitudinal ends of the auxiliary belt auxiliary belt with an additional force component, which acts transversely or obliquely to the auxiliary belt.

The support element may be selectively supported on the auxiliary belt or on the belt or support the auxiliary belt or belt over a certain length. If we adjust the support element in this case, it acts over the entire supported length range on the auxiliary belt or belt, which can generate a significantly higher tension than is possible with a purely punctual support.

But it is also conceivable that two auxiliary straps are present and the support element is supported on the two auxiliary straps. It is then z. B. conceivable that the support member is supported on the other auxiliary belt and both auxiliary belts z. B. deflects in equal parts. In particular, this is conceivable in an embodiment in which the support element laterally deflects the auxiliary belt in a direction substantially parallel to the ski surface. A deflection parallel to the ski surface may form a preferred embodiment, if z. B. the height of the transmission elements or the entire transmission device should be kept as low as possible.

One possible embodiment of such a support element may, for. B. a four-bar linkage with four corner joints and four articulated arms comprise. The four-bar linkage is then arranged, for example with a plane of the four-bar linkage parallel to the ski surface on the ski body, such that two opposite corner joints of the four-bar linkage are arranged on a central longitudinal axis. A front of the two longitudinally arranged corner joints is then z. B. supported on the ski body, while the opposite Corner joint is attached to the front end portion of the belt. If now a displacement of the belt, so the two other, free, corner hinges depending on the force in the belt, ie tensile or compressive force or displacement of the belt to the rear or forward, transversely to the longitudinal direction of the ski moves inward or outward or pressed. At the free corner joints z. B. driver formed, which are respectively supported on a respective in the sense of a chord the steering range spanning auxiliary belt and take the auxiliary straps outwards or inwards and thus laterally, parallel to the ski surface deflect.

An embodiment with a height-adjustable support element, which deflects the auxiliary belt away from the ski, has the advantage that not only the tensile force in the auxiliary belt is generated by the deflection of the auxiliary belt but also the tension angle, d. H. the angle under which the tensile force acts on the ski body at the anchored longitudinal ends of the auxiliary belt, is variable by the support member such that there is an improved effect of the tensile force for bending the steering range. In particular, results in an embodiment with a height-adjustable support element, which is arranged between the ski body and hip belt, from a height adjustment of the support element, a lateral deflection of the auxiliary belt away from the ski. With the deflection away from the ski, the draw angle of the tensile force generated in the auxiliary belt is also increased, so that the component of the tensile force effective for the deflection of the steering range is also increased. One possible embodiment of the height-adjustable element comprises z. B. a pivotable about a transverse axis hinged to the ski body lever, which is arranged between the auxiliary belt and ski body such that the auxiliary belt is guided over a lever end remote from the lever and the lever can be pivoted due to the pressing force of the pressure belt.

However, it is also conceivable to make the adjustable support element displaceable or adjustable in the longitudinal direction between the two attachment locations of the auxiliary belt, wherein it is arranged between the auxiliary belt and the ski body. Due to a displacement of the belt then the support element z. B. also moved in the longitudinal direction. Does the auxiliary belt between the mounting locations a variable distance to the ski body on, so can be increased or reduced in the support member supported on the auxiliary belt by the displacement of the support member, a tensile stress.

In a further preferred embodiment, the transmission elements of the transmission device may comprise a gear which cooperates positively and / or non-positively with the belt and preferably with the auxiliary belt. In particular, at least one gear is present, which cooperates positively or non-positively with the belt, preferably acts between the belt and auxiliary belt. The gear is z. B. rotatably mounted about a vertical axis on the ski body. If the gear z. B. formed by a gear, so are partially in the belt and the auxiliary belt z. B. teeth formed which engage in the gears. In particular, the belt and the auxiliary belt then engage on opposite sides of the bearing in the at least one gear. In a displacement of the belt in a first direction, the gear rotates in the appropriate sense and forces the auxiliary belt to shift in the opposite direction. But it is also conceivable that belt and auxiliary belt cooperate via a plurality of gear wheels, which allow, if necessary, a transmission or reduction of the forces or torque transmission. Likewise, one or more non-positive gears are conceivable, which form the transmission.

In principle, however, transmissions in the transmission device can also be used in such a way that the transmission elements do not interact directly with the belt and / or the auxiliary belt. In this case, however, further elements of the transmission device are required, which is generally not desirable due to the increasing complexity of the transmission device.

However, it is also conceivable that the transmission elements of the transmission device comprise a joint arrangement. It is Z. B. an embodiment possible, which comprises an articulated arm which is rotatably mounted at one of its longitudinal ends about a vertical axis of rotation on the ski body. Belt and auxiliary belt then grab z. B. on the same side of the rotatable mounting on the articulated arm. This is z. B. a force-over- or - achieved reduction, depending on which of the straps with the smaller leverage on the articulated arm attacks. But there are also any other versions of joints such. B. four-bar linkages, stork beaks or similar known joint arrangements applicable. In principle, any joint and / or gear arrangement which appears suitable for the transmission of forces can be used in a ski according to the invention.

Preferred is an embodiment of the invention, in which the transmission elements of the transmission device comprise a rocker joint with respect to the joint bearing two opposite arms. The rocker joint is then preferably mounted rotatably about a vertical axis on the ski body. On one of the arms of trained as a pressure or tension belt belt engages pivotally and on the second, opposite arm, preferably engages the auxiliary belt. But it can also cooperate with another rocker or a gear with the opposite arm for transmitting the tensile force, so that the transmission device acts overall with a tensile force on the steering area. In particular, while the belt at a different distance from the joint bearing, d. H. with another lever arm, attack the articulated arm as the auxiliary belt. This results in a transmission or reduction of the forces or moments transmission. However, the lever arm on the rocker joint of the auxiliary belt can also be the same size as the lever arm of the belt, resulting in a magnitude same transfer of moments.

The transmission device according to the invention can be used equally advantageously in straps that are load-bearing as well as in tension. Depending on the type of belt thus differ the requirements of the transmission device.

For certain skis, an essentially tension-resistant tension belt is advantageously used. For example, in different cases, a guidance of a tension belt on the ski body can be implemented more simply than the guidance of a pressure belt. The tension belt can z. B. may be formed as a rope or band comprising a metal, a mesh of metal, a mesh of fibers or other suitable appearing materials. The force along the tension belt is then a tensile force, which z. B. can act directly through the belt or a transmission device on the steering range. In an embodiment of a dynamic ski with a tension belt, the belt is guided in the control area below the board body, in particular below a neutral fiber of the board body or of the ski. Thus, with a positive deflection in the control area, a tensile force in the tension belt generated, which can be removed from the transmission device and can be transmitted to the steering area.

According to the invention, however, in the case of a dynamic ski, a pressure belt which can be subjected to pressure in the main can also be used. The ski of a corresponding embodiment comprises, in addition to the ski body, the pressure belt which can be subjected to pressure and which is supported and / or anchored to the at least one support point on the ski body. In this case, the pressure belt is guided in the at least one control region with respect to the ski body in the longitudinal direction of the snow gliding board substantially parallel and longitudinally displaceable.

The force along the pressure belt due to the deflection of the snowboard in the control area is in this case a compressive force, the pressure belt is guided in the control area above the board body, in particular above a neutral fiber of the board body, and in particular the pressure belt with respect to the Längsdurchbiegung in the control area with the Schneegleitbrett is positively coupled. Designs with a compression belt may be preferred because of better control and easier removal of the force generated in the belt. In particular, in heavy-duty applications, a compression belt is generally preferred, since these are typically resilient to pressure and tension and thus allow additional functionality with simpler design. In particular, the deflection in the control area can thus be forcibly coupled to the steering area with little effort in a simple manner. A pressure belt which is guided displaceably in the longitudinal direction and positively coupled in the control area is capable of converting a positive as well as a negative deflection of the control region of the ski in a displacement of the pressure belt to the front or to the rear. About a suitably trained transmission device, this shift can then be transmitted in a deflection of the steering range of the ski, which can then be bent in the same direction or in opposite directions as the control area depending on the requirements. Such embodiments are made possible only by the inventive transmission device, which allows a transmission of the pressure force arising in the pressure belt in the tensile force on the steering range. In addition, a pressure belt allows an execution of the ski, in which the essential parts the belt, the transmission device and the auxiliary straps are formed on the upper side of the ski body.

In order to be able to optimally convert the compressive force generated, for example, in the pressure belt by the displacement in the control region for the deflection of the steering region, the tensile force on the steering region is preferably directed such that it is substantially opposite to the pressure force of or in the pressure belt. This is particularly preferred when the support point is arranged at a longitudinal end of the ski facing away from the steering area. With such a substantially anti-parallel alignment of the tensile force to the compressive force of the entire amount of force of the tensile force acting in the longitudinal direction of the ski and is therefore basically usable for the deflection of the steering range. In particular, however, in the case of a tension belt, the tensile force along the belt may be directed counter to the tensile force on the steering area.

However, it is quite conceivable that a deviation of the tensile force direction of the longitudinal direction or the direction of the force in the belt z. B. the compressive force of the compression belt can form a preferred modification of the invention. Such deviations may be required to reduce the tensile force of z. B. a centrally guided in the control area push rod to transfer areas of the steering area, which are arranged laterally of a central axis of the ski.

However, in particular in embodiments in which a pressure belt is supported at a support point near the steering area on the board body, it may also be preferred that the direction of the tensile force on the steering range of the direction of the force along the belt, in particular the compressive force of the pressure belt, substantially is addressed the same. A particularly preferred embodiment comprises a pressure belt, which is supported in a front region of the ski at the steering area via the support point. The free end of the pressure belt is then arranged at a rear end of the ski and is at a

Deflection in the control area shifted backwards. At the free end, for example, is anchored to a train loadable auxiliary belt, which is guided in the control area below the ski to the steering area, where it is anchored above the ski on the board body. In such an arrangement, not only does the pressure belt "feel" the deflection of the ski, but in addition to reinforcing the auxiliary belt guided underneath the ski, which is additionally stretched due to the deflection. The forces in the belt and the auxiliary belt are thus rectified. By the auxiliary belt acts directly in the steering area and thus the tensile force on the steering range of the force along the belt is substantially rectified. This results in particular, an example of an embodiment of the transmission device, which not only transmits the force along the belt, but also assumes the function of an amplifier, which increases the force along the belt by the deflection of the ski is better used. The additional tensile force generated in the auxiliary belt itself due to bending of the ski is also added to the force transmitted by the auxiliary belt by the pressure belt. Basically, embodiments with both equal and opposite forces are conceivable, but due to the specific requirements of the ski is to be weighed, which solution offers the greater benefits. Depending on the design, the transmission device is to be configured in such a way that ultimately the force along the belt is transmitted in an optimal manner into the tensile force on the steering region. In various embodiments of the invention, an amount-wise one-to-one transfer of force along the belt may be desirable as a pulling force on the steering region of the ski. With a transfer of forces varying in magnitude, however, the ski according to the invention can be applied even more versatile. The transmission device then has a transmission or reduction of the occurring forces or moments. It is Z. B. conceivable to increase the force on the steering area by the tensile force has a higher amount than the force along the belt. This can be z. B. achieve a greater deflection effect in the steering range even at a low deflection in the control area. The over- or reduction can be adjustable in a variant of the invention by the skier, so that the ski can be adapted to the current conditions. Overall, such a transmission device thus allows, as required, a transmission of the compressive forces in the pressure belt in tensile forces on the steering area, which differ directionally and / or amount of the compressive force. An amount difference in the tensile force against the force along the belt can also be achieved for example by a dynamic design of the auxiliary belt, z. B. by the auxiliary belt is elastic. The auxiliary belt transmits then the forces of the belt z. B. depending on the instantaneous strain in different ways.

In principle, a dynamic design of the auxiliary belt and / or the belt in all implementations of the invention form a preferred embodiment. A z. B. elastic belt may have such elasticity that occurring vibrations are damped in the belt, without significantly affecting the force transmitting effect of the belt. The same applies to the auxiliary belt, which may also be elastic. However, it is conceivable that a certain degree of elasticity can also play a role in the functionality of the belt or of the auxiliary belt or the transmission device by the respective belt z. B. as a function of the elasticity forces transfers different strengths. Due to the elasticity but also a force can be stored in the belt and retrieved when needed, which can be used under certain circumstances with advantage.

In a preferred embodiment, the snow sliding board is largely uniformly deflected due to the tensile force in the steering area with respect to a direction transverse to the longitudinal direction over substantially the entire width of the snow gliding board. As already mentioned, however, a steering range can also be used with advantage on different ones

Be charged with different tensile forces, causing z. B. in addition to the deflection, for example, gives a twist of the ski about the longitudinal axis. It is conceivable, for example, attacking the transmitted from the transmission device tensile force in, for example, two different distances from the central axis attack locations in the steering area.

For a versatile ski, however, it may be advantageous to make a deflection in the steering area transverse to the longitudinal direction uniform, so that there is no need to distinguish between a right or left ski when using. However, there are other areas of application (eg ski racing, professional ski area) in which an optimization of the deflection behavior in the steering area can also be useful in a direction across the ski. In particular, in these cases with the transmission device according to the invention, the tensile force can be transmitted to the steering area in such a way that in addition to the deflection, there is also a distortion transverse to the longitudinal direction of the ski is generated. In a particularly advantageous embodiment, the board body is subdivided into a length region of the steering region into a plurality of sections which are largely independent with respect to a longitudinal deflection. In this case, at least one of the several sections is subjected to the tensile force. In one variant, the several sections are subjected to, for example, different tensile forces in terms of magnitude and / or direction. However, a selective application of force to the individual sections is not necessary. A subdivision of the steering range into several sections can, for. B. also be in the already described above symmetrical tensile forces on the steering range a preferred embodiment. Preferably, the steering area is divided into an inner and an outer section. Lying inside and outside refers to the arrangement of the skis when used by a skier. Each ski has during use a respective side facing the other ski, which is hereinafter referred to as lying inside. Accordingly, a side facing away from the other ski is referred to as lying outside. In an embodiment which is preferred depending on the requirement, the entire tensile force largely acts on the inner section, while the outer section is not subjected to any tensile force. In such an embodiment, only the inner region of the steering region is deflected, while the outer portion remains largely unchanged. Particularly advantageous here is an embodiment of the inventive ski with a divided into two halves steering range. The transmission device is then designed, for example, such that it transmits only a tensile force to the respective inner section of the steering region. In a modification, the transmission device transmits different-sized tensile forces to the respective sections of the steering area. A subdivision of the steering range into the abovementioned sections can also be advantageous in the case of a magnitude symmetrical admission with a pulling force. In particular, the sections of the steering area with respect to the longitudinal central axis of the ski are also advantageously formed symmetrically. In such a preferred embodiment, a steering range, for example, a central dividing slot and a transmission device of the ski comprises an auxiliary belt, which in each case with one of its two longitudinal ends in one of the two through the slot formed sections attacks. The transfer device then comprises, for example, a deflection roller fixed to the belt, around which the loop so formed by the auxiliary belt is partially guided, such that the deflection roller tensions the auxiliary belt during a displacement, ie generates a tensile force in the auxiliary belt. Due to the guide around the pulley around the traction along the entire auxiliary belt at any time in terms of amount is largely constant. Depending on the momentary deflection in the respective section z. B. when cornering, however, results in a different angle of attack of the tensile force, which can be used advantageously and allows further adaptation of the inventive ski. The sections of the longitudinal region thus allow for a suitable tensile force distribution targeted, sections bending the steering range, which makes the steering of the ski to a desired cornering behavior customizable. In particular, for example, the tension distribution can be preset to the different sections of the skier in order to adapt the ski to the current requirements can. In principle, it can thus be stated that a steering area subdivided into sections further improves the versatility of the ski according to the invention. Overall, symmetrical and asymmetrical embodiments of the longitudinal deflection independent Lenkbereichsabschnitte are conceivable, with the tensile force and the tensile forces can attack in terms of amount and / or directionally symmetrical or asymmetrical at the respective sections.

In a further modification of the invention, the control region of the ski can also have several sections which are largely independent with respect to a longitudinal deflection. Thus, the advantage can be achieved that, for example, arranged in one of the sections of the control belt belt deflection of another of the sections does not "feel", ie from the deflection in the other section, no or only a slight shift of the belt relative to the board body results. With such a subdivision of the control region, a more selective control of the displacement of the belt can thus be achieved, wherein in particular a particularly strong or a particularly weak displacement can be achieved. In all the aforementioned embodiments, it is conceivable to provide a plurality of belts on a ski. The several straps can z. B. act directly or indirectly on one or more of the steering areas of the ski (especially at Zuggurten). But the straps can also act on one or more steering areas of the ski via a common transmission device according to the invention or via a plurality of, for. B. to each belt associated transmission device, the or the steering areas or sections of the steering areas of the skis act on corresponding tensile forces.

In all cases, the straps are preferably guided substantially parallel and in the longitudinal direction of the ski in order to optimally transfer pressure or tensile forces along the straps due to longitudinal deflection of the ski. Depending on the requirement, it is also conceivable that in another embodiment deviations from a parallel orientation, for. B. a converging arrangement, is preferred to z. B. to be able to implement the transverse bending (torsion) in a distortion of the ski in the tax area. In this case, it is z. B. also conceivable that an asymmetrical arrangement of the straps with respect to a longitudinal axis of the ski forms a preferred embodiment. Preferably, however, the plurality of straps are arranged symmetrically in order to be able to implement a longitudinal deflection in the control area symmetrically in force actions.

A possible embodiment comprises z. B. two substantially parallel guided pressure belts with control areas in different longitudinal areas of the ski, the compression straps each having an associated transmission device with a tensile force acting on a respective steering range, wherein the two steering areas of the two straps are arranged opposite each other on the ski. One of the compression straps can z. B. have a front / middle control area and act on a steering area in the rear ski area, while the second parallel thereto substantially parallel pressure belt has a rear / middle control area and acts with a pulling force on a steering area in the front ski area. It is understood that this embodiment may be modified such. B. another embodiment of the control areas and / or a common deflection device for both compression straps.

A similar embodiment is conceivable with a system of two belts, wherein the control portion of a first belt has a front / middle control area and acts on a steering area in the rear ski area and the second belt a has rear / middle control area and acts on a steering area in the front Skiendbereich.

Designs with compression and tension straps according to all described embodiments can basically be freely combined. In particular, skis according to the invention are conceivable in which one or more compression straps and one or more tension belts cooperate with one another in such a way or interact with the transmission device such that the flexing effect, ie. H. the forces generated along the belts, which are transmitted by the transmission device as tensile forces on the steering range, cumulate in whole or in part. Here, two or more of the various embodiments of the invention described above and below may be combined with each other in a single embodiment of a ski according to the invention.

A further object of the invention is to provide a snow gliding board, in particular a ski, which is associated with the abovementioned technical field, with a tension belt which can be subjected to tensile stress, which offers the possibility of making the deflection behavior of the snow gliding board more versatile and improving.

In order to achieve the further object, a snow gliding board according to the invention comprises a board body and a tension belt which is essentially load-bearing, which is anchored to the board body at at least one support point, wherein the tension belt is longitudinally displaceably guided in at least one control area and with respect to a longitudinal deflection in the control area with the snow gliding board is coupled. The Schneegleitbrett is characterized in that means are provided which transmit a due to a deflection of the Schneegleitbretts in the control area resulting force along the Zuggurtes in a tensile force that engages in a steering range at a longitudinal end of the Schneegleitbretts on the board body such that the Schneegleitbrett in the steering area is bent. In particular, the snow sliding board is lifted in the steering area of a pad, ie positively bent. This aspect of the invention as well as the modifications described below can also be used in all the above-described embodiments of a ski according to the invention with a transmission device or combined with them in the sense of the invention. It is z. B. conceivable that belt systems are provided with and without transmission device on the same ski.

As above, z. As "skis", "ski body", "Skieendbereich" etc. as a representative but not limiting for "snow sliding board" and the corresponding terms used. Also, other conventions such as "front", "rear", "top" and "bottom" are used in relation to the ski or the ski body as in the above part of the application. The tension belt is preferably guided in the steering area above the ski body, in particular above the neutral fiber of the board body. With the guide above the ski body and engaging the Zuggurts in the steering area is achieved that a tensile stress generated in the tension on a top of the ski in the steering area on the ski body can attack. Due to the guidance of the Zuggurts in the control area below the ski body is achieved that in a positive deflection of the ski, a tensile stress in the tension belt is generated. This is in particular a consequence of the anchoring on both sides (supporting point, attacking in the steering area) of the tension belt on the ski body. In this case, any suitable material for transferring a tensile force in a suitable design is considered a tension belt. In particular, the tension belt z. B. be formed by a tape or rope, which z. B. fibers from z. As aramid or a metal comprises. Likewise, however, a tension belt can also be formed from a comparatively stiff material and at the same time be loadable under pressure. But there are also other designs of other materials and / or shapes conceivable. The material and form examples mentioned above do not represent exhaustive enumeration and should be understood as exemplary variants.

According to the invention, the tension belt must not be biased, but should not have any play in order to have a noticeable increase in the tensile force in the tension belt even at a low deflection. But it is also conceivable that the tension belt, if necessary, has a bias, which z. B. can also be adjusted by the skier to the reaction of the steering range of the ski to a deflection in the Tax area z. B. the personal needs or the discipline in which the snow sliding board is used to adapt.

The tensile force can thus be used in such a way that the steering region also experiences a positive curvature or deflection in the case of a positive deflection of the control region. The same direction curvature is achieved in this embodiment of the invention by crossing over pressure belt (ski body) and tension, z. B. at a transition from the control area to the steering area. A crossover can z. B. be formed by a simple implementation of the tension belt through the ski body. For this purpose, an opening is formed in the ski body, for example, through which the tension belt can pass from the underside of the ski in the control area to the top of the ski in the steering area.

In particular, in a preferred embodiment, a further steering range is present, wherein the means transmit the force along the tension belt as a tensile force on both steering areas, so that the Schneegleitbrett is deflected at a deflection in the control area in both steering areas.

Preferably, the two steering areas are formed at opposite longitudinal ends of the ski, d. H. one steering area at a front and at a rear longitudinal end.

In a preferred embodiment, the tension belt, in particular in the sense of a pulley, is guided parallel in the control area in multiply alternating sections in the longitudinal direction. At the extreme longitudinal positions, d. H. At the respective front and rear reversal points of the alternating multiple longitudinal guide, the tension belt is mounted such that a longitudinal displacement of one of the sections or a force along one of the sections is transferable to a further section connected to this section. In particular, the tension belt is mounted with slippage on the ski body.

Preferably, the tension belt is mounted such that it is guided in the control area from the bottom to the storage in or on the ski body around back to the bottom. In the case of a longitudinal displacement in one of the parallel sections, this can be transferred to the next, in particular adjacent, section. This results in a pulley-like construction, which due to the alternating multiple leadership in the control area allows to feel a deflection in the control area reinforced, ie a deflection generates a larger displacement of the tension belt in the steering area, as it would be the case with a simple longitudinal guide. In a first approximation, the longitudinal displacement of Zuggurts in the steering range over a simple guide multiplied by the number of parallel sections in the control area.

Particularly preferred is a snow sliding board according to the invention with a tension belt and a board body which, substantially in the longitudinal region of the steering area, is subdivided into a plurality of sections which are largely independent with respect to a longitudinal deflection. In this case, the individual sections are subjected to different tensile forces with advantage. In particular, the steering area is divided into an inner and an outer portion, wherein the tension belt engages with the tensile force on the inner portion, while the outer portion is subjected to no or only a slight tensile force. As already described above, in a subdivision of the steering range in symmetric and asymmetrical embodiments are largely conceivable with respect to a longitudinal deflection, with the tensile forces on the respective sections amount and / or direction symmetric or asymmetric attack.

Ways to carry out the invention

1 a shows a plan view and FIG. 1 b shows a side view of a ski 1 according to the invention with a ski body 2, a pressure belt designed as a push rod 3 and a transmission device 4. The ski 1 is in a forward region 21 of FIG a Fahrunterlage bent up, as is the case with conventional skis.

The push rod 3 has in the illustration of Figure 1 a-d a length which corresponds to about two-thirds of the entire length of the ski 1. The push rod 3 is arranged in a rear region of the ski 1, which comprises about two thirds of the length of the ski. The push rod 3 is arranged in the longitudinal direction A of the ski 1 and centrally with respect to a direction transverse to the longitudinal direction A, such that a rear longitudinal end 5 of the push rod 3 terminates substantially with a rear longitudinal end 6 of the ski body 2. In an area at the longitudinal end 5, the push rod 3 is connected to a support point 7 with the ski body 2. Over the remaining length of the push rod 3, this is displaceable relative to the ski body 2 in the longitudinal direction, a control area 10 forming guided (guiding device not shown). In the control region 10 of the ski 1, the push rod 3 is supported in particular with a deflection of the ski 1 via the support point 7 on the ski body 2 relative to the ski body 2 slidably. With a positive deflection of the control area 10, d. H. When the rear ski end 6 is lifted from a base relative to a central region of the ski 1, a displacement of a front longitudinal end 8 of the push rod 3 from a rest position 1 1 relative to the ski body 2 in the direction of a front longitudinal end 9 of the ski 1 out. The rest position 1 1 is defined by the position of the longitudinal end 8, when no external loads on the ski 1 act.

The transfer device 4 is arranged substantially in a front third of the ski 1. In the illustrated embodiment, the transfer device 4 comprises two auxiliary straps 13.1 and 13.2 which can be loaded essentially in tension and two Deflection rollers 14.1 and 14.2, which each above the ski body 2 with respect to a plane E, which is perpendicular to a ski top 16 and includes the longitudinal axis A, are arranged symmetrically. The auxiliary straps 13 preferably have a low, substantially vanishing, elasticity. The pulleys 14.1 and 14.2 are arranged on both sides of the push rod 3 set back from the rest position 1 1 to the rear end 6 of the ski. The pulleys 14.1 and 14.2 are rotatably mounted on the ski body 2 with axes 15.1 and 15.2 arranged perpendicular to the ski surface 16. The auxiliary straps 13.1 and 13.2 are on the one hand in each case with a longitudinal end 17.1 and 17.2 anchored in the bent portion 21 from above in or on the ski body 2. The region between the anchored longitudinal ends 17 and the deflection rollers 14 forms a steering region 12 of the ski 1, wherein the deflection rollers 14 are arranged at a rear longitudinal end 19 of the steering region and the anchored longitudinal ends 17 at a front longitudinal end 18 of the steering region 12. The control region 10 overlaps Thus, with the steering portion 12, the amount by which the pulleys 14 are offset from the longitudinal end 8 to the rear.

With their further longitudinal ends 20.1 and 20.2, the auxiliary straps 13.1 and 13.2 are fastened in a region at the front longitudinal end 8 of the push rod 3. Of the longitudinal ends 17.1 and 17.2, the auxiliary straps 13 are each guided with respect to a plane E, which is perpendicular to the ski surface 16 and includes the longitudinal direction A, from the outside to the guide rollers 14.1 and 14.2 introduced and substantially around half a turn around this. After the half turn, the auxiliary straps 13.1 and 13.2 are guided away from the deflection rollers 14.1 and 14.2 and towards the region at the longitudinal end 8 of the push rod 3, to which the longitudinal ends 20.1 and 20.2 are anchored.

The auxiliary straps 13 are freely floating in the illustration of FIG. 1 ac between the longitudinal ends 17 and the guide rollers 14, but in an embodiment not shown but also on a z. B. upwardly arched flexible shoe freely slidably guided. In particular, the auxiliary straps 13 engage at an angle α to the surface of the ski 1 on the ski body 2. But it is also conceivable that the auxiliary straps covered 13, z. B. partially in the ski body 2, are performed. If now the front longitudinal end 8 of the push rod 3 is displaced toward the front ski end 9, a pressure force 30 acts along the push rod 3 via the support point 7, which is also directed to the front end of the ski 9. Since the longitudinal ends 20 of the auxiliary straps 13 are anchored to the push rod 3, they are also moved to the front end 9 and pressed down. The tension forces 32.1 and 32.2 thus produced are transmitted to the longitudinal ends 20.1 and 20.2 along the auxiliary straps 13.1 and 13.2 on the longitudinal ends 17.1 and 17.2 via the auxiliary straps 13.1 and 13.2 which can be loaded on the train.

Since the auxiliary straps 13.1 and 13.2 are guided around the respective deflection rollers 14.1 and 14.2 by a substantially half revolution, the tensile forces 31.1 and 31.2 resulting from the longitudinal ends 17.1 and 17.2 are opposite to the pressure force 13, ie. H. towards the rear end of the ski 6. Since the longitudinal ends 17 are anchored in the ski body, the tensile forces 31 act on the steering area 12 of the ski 1.

FIG. 1c shows a side view of the ski 1 in a positively bent state. In particular, the ski 1 is bent in the longitudinal direction A such that the ski 1 in the control region 10 has a curvature, which is indicated in FIG. 1c as a circular arc 33. The illustration in FIG. 1 c is aligned with respect to FIGS. 1 a and 1 b such that the rear longitudinal end 19 of the steering region 12 is not displaced relative to a background or a base.

Due to the deflection in the control area 10, the front longitudinal end 8 of the push rod 3 is shifted relative to the rest position 1 1 by a length amount 34 to the front end 9 of the ski. The pressure force 30 acts as tensile forces 32.1 and 32.2 in the direction of the front end of the ski 9 on the longitudinal ends 20.1 and 20.2 of the auxiliary straps 13.1 and 13.2. The auxiliary straps 13.1 and 13.2 transmit the tensile forces 32.1 and 32.2 via the deflection rollers 14.1 and 14.2 to the longitudinal body anchored in the ski body 2 17.1 and 17.2, where the tensile force as tensile forces 31.1 and 31.2 at the front longitudinal end 18 of the steering portion 12 substantially in the direction of the rear end of the ski 6 act.

Due to the tensile forces 31, which act as tension in the steering area 12 between the guide rollers 14 and the anchored longitudinal ends 17, the steering area 12 of the ski 1 undergoes a deflection. In other words, the longitudinal ends 18 and 19 of the steering area 12 attracted to each other by the attack areas of the tensile forces lying there, whereupon the ski 1 bends in the steering area.

The deflection is generated in particular by the tensile forces 31 acting on the ski body 2 from above. This results in a non-vanishing force component 36, which at the anchoring of the longitudinal ends 17, d. H. in the attack region of the tensile forces 31, perpendicular to the surface 1ό of the ski 1 stands. This results in a force which is directed away from the base and which is able to lift and deflect a front ski area, in particular the steering area 12, away from a base. The deflection in the steering area 12 in this case has a curvature 35, which in the illustration of Fig. 1c has a smaller radius of curvature than the curvature 33. The deflection in the steering area 12 is not by a force in the steering area 12 of the driving surface (snow resistance) on the Ski 1 achieved, but by transmitting the deflection of the ski 1 in the control area 10th

The embodiment described in Fig. 1 a-c thus allows deflection of the ski 1 in the steering area 12 for turning a front ski area due to a deflection of the ski 1 in the control area 10th

With a suitable design of the pulleys 14, z. As in eccentric storage, not only a deflection of the pressure force 30 of the push rod 3 can be achieved in a tensile force 31, but it is also a magnitude excessive or reduction of the forces possible. This can be due to a relatively small deflection in the control area z. B. a relatively large deflection in the steering area 12 are generated, d. H. the deflection in the control area 10 can be "mechanically strengthened".

FIG. 1d shows a further embodiment of a ski 1 according to the invention with a transmission device 4.1 with deflection rollers 14.1 and 14.2. In contrast to the embodiment of Fig. 1a, however, the transfer device 4.1 comprises only one auxiliary belt 22. In a region at the front longitudinal end 8 of the push rod 3, a further guide roller 14.3 is rotatably mounted on the push rod 3 about a vertical axis 15.3. Preferably, pulleys of the pulleys 14.1-14.3 are substantially in one plane. The auxiliary belt 22 is with its two longitudinal end 23.1 and 23.2 in bent portion 21 anchored from above in or on the ski body 2 (analogous to the anchorages of the longitudinal ends 17.1 and 17.2 of the embodiment according to FIG. 1 a).

Of the longitudinal end 23.1 of the auxiliary belt 22 is brought with respect to the plane E from the outside to the guide roller 14.1 and guided around this substantially by half a turn around them. After the half turn, the auxiliary belt 22 is guided in opposite directions essentially by half a turn around the deflection roller 14.3 of the push rod and from there is guided from the inside to the deflection roller 14.2. Again in the opposite direction to the leadership of the role 14.3, d. H. in the same direction to the guide around the guide roller 14.1, the auxiliary belt 22 is guided around a half turn around the guide roller 14.2 and from there to the anchored longitudinal end 23.2. The auxiliary belt 22 thus has a substantially w-shaped guide, wherein the arms of the W-shape areas 24.1 and 24.2 of HilfsgUrts 22 correspond, which of the attached to the ski body 2 pulleys 14.1 and 14.2, substantially parallel to the anchored longitudinal ends 23.1 and 23.2 lead. The three prongs of the W-shape are formed by the pulleys 14.1-14.3. With a displacement of the front end 8 of the push rod 3 to the tip of the ski 9 towards the deflection roller 14.3 presses with a force 30 on a portion 24.3 of the auxiliary belt 22, which is arranged substantially between the guide rollers 14.1 and 14.2 and is guided around the guide roller 14.3. Thus, along the auxiliary belt a tensile force 32.1 or 32.2 results around the deflection rollers 14.1 and 14.2, which acts as traction 31.1 and 31.2 on the anchored longitudinal ends 23.1 and 23.2 of the auxiliary belt. The auxiliary belt 22 may in this case also be guided in a U-shape around the deflection rollers 14.1 and 14.2, wherein the deflection roller 14.3 in the rest position of the ski 1, d. H. without external load, no or only tangential contact with the auxiliary belt 22 has. Only with a displacement of the end 8 of the push rod to the front then results in the above-described W-shape of the auxiliary belt guide.

This embodiment has over the embodiment of Fig. 1a has the advantage that z. B. different loads on the two Hilfsgurtbereiche 24.1 and 24.2 (ie, the arms of the W-shape) can be compensated because the two areas 24.1 and 24.2 are slidably connected together (over the area 24.3). This is of great advantage, in particular with a twisting of the ski 1 in the steering area 12. Figures 2a and 2b show the views of Fig. 1a and 1b corresponding representations of another embodiment of a ski 101 according to the invention with a height-adjustable support member 1 14. Figure 2c shows an enlarged view of a functional sketch of the support member 1 14. The ski 101 is in a in an intended direction forward region 121 bent by a driving support, as is the case with conventional skis.

The ski 101 has a ski body 102, a pressure belt 103 formed as a compression belt and a transmission device 104. The push rod 103 has in the representation of Fig. 2a and 2b, a length which corresponds to about three quarters of the entire length of the ski 101. The push rod 103 is arranged parallel to a longitudinal direction B of the ski 101 and centrally with respect to a direction transverse to B, wherein a rear longitudinal end 105 of the push rod 103 substantially terminates with a rear longitudinal end 106 of the ski body 102. In the region of the longitudinal end 105, the push rod 103 is connected to the ski body 102 at a support point 107. Over its remaining length, the push rod 103 relative to the ski body 102 in the longitudinal direction B slidably guided in a control area 1 10 (guide not shown). As in the case of the embodiment of FIGS. 1 a-c, in the case of a positive deflection of the ski 101 in the control region 110, a displacement of a front longitudinal end 108 of the push rod 103 from a rest position 1 1 1 relative to the ski body 102 toward a front ski end 109. The rest position 1 1 1 is defined by the position of the longitudinal end 108 when no external loads act on the ski 101.

The transfer device 104 of the ski 101 is formed substantially in a front third of the ski 101. In the illustrated embodiment, the transfer device 104 comprises two substantially tension-sensitive auxiliary straps 1 13.1 and 1 13.2, which are each above the ski body 102 with respect to a plane D, which is perpendicular to the ski surface 1 16 and which includes the longitudinal axis B, are arranged symmetrically , The auxiliary straps 1 13 preferably have a low, substantially vanishing, elasticity. The auxiliary straps 1 13.1 and 13.2 are on the one hand in each case with a front longitudinal end 1 17.1 and 1 17.2 at a front end 1 18 of a steering range 1 12 anchored to the ski body 102. In particular, lie the Anchorages of the longitudinal ends 1 17.1 and 17.2 of the auxiliary straps 1 13.1 and 1 13.2 in the bent-up area 121.

Rear longitudinal ends 120.1 and 120.2 of the auxiliary straps 1 13.1 and 13.2 are also in the

Ski body 102 anchored. The longitudinal ends 120 lie at a rear longitudinal end 1 19 of the steering portion 1 12. The anchoring of the longitudinal ends 120 is preferably about a

Length offset from the rest position 1 1 1 to the rear end of the ski 6, which essentially the distance of the rest position 1 1 1 of the anchoring of the longitudinal ends 1 17, d. H. the

Distance from the front longitudinal end 1 18 of the steering range 1 12 corresponds. The resting position

1 1 1 is thus substantially with respect to the longitudinal direction B in the middle of the steering portion 1 12, in particular between the anchored longitudinal ends 1 17 and 120, respectively.

Furthermore, the deflection device 104 comprises a height-adjustable support element 14. The support element 14 has a lever 1 15 articulated on the ski body 102. The lever 1 15 is pivotable about a rotation axis C transverse to the longitudinal direction B and parallel to the ski surface 1 16. The axis of rotation C of the lever 1 15 is substantially in a length range of the rest position 1 1 1. The support member 1 14 is formed such that it can be arranged between the auxiliary straps 1 13 and ski body 102. In particular, the support element 1 14 is arranged such that a gelenkfernes end 1 17 of the lever 1 15 supports the auxiliary straps 1 13 and supported against the ski body 102. The distance of the gelenkfernen end 1 17 of the lever 1 15 of the ski surface 1 16 depends on the respective pivotal position of the lever 1 15 from. This is, by the lever 1 15 is brought into different pivot positions, a height adjustment of the support member 1 14 reachable.

In the embodiment of the invention according to FIG. 2a-c, the push rod 103 is coupled to the lever 1 15 of the support member 1 14, z. B. articulated that due to a displacement of the front longitudinal end 108 of the push rod 103 from the

Rest position 1 1 1 towards the front end of the ski 109 of the lever 1 15 "set up" and at

Return to the rest position 1 1 1 the lever 1 15 is lowered again. Ie. the distance of the end 1 17 from the ski surface 1 16 can be increased or reduced again due to a corresponding displacement of the longitudinal end 108 of the push rod 103. Since the auxiliary straps 1 13 at the end 1 17 of the lever 1 15 supported When setting 138 of the lever 1 15, the auxiliary straps 1 13 experience a lateral deflection 137, ie substantially perpendicular to their longitudinal direction, away from the ski 101. When the lever 1 15 is lowered again, the lateral deflection 137 is also reduced. A positive deflection of the control portion 1 10 thus generates due to the associated displacement of the push rod 103 via the lever 1 15 of the support member 1 14 a tension 131.1 and 131.2 in the auxiliary straps 1 13.1 and 1 13.2. The tensile forces 131 engage the longitudinal body 1 17 or 120 anchored in the ski body 102 on the ski body 102. FIG. 2 c shows a functional sketch which shows the steering region 1 12 with deflection device 104 of the ski 101 in a rest position 122 without external loads (pulled through) and in a position 123 in which the front longitudinal end 108 of the push rod 103 (not shown) from the rest position 1 1 1 is moved forward (dashed). In the rest position 122, the lever 1 15 is lowered substantially to the ski surface 1 16. In particular, the lever supports 1 15, the auxiliary straps 1 13 not or only slightly. If now a displacement of the longitudinal end 108 of the push rod 103 to the front, so the lever 1 15 is placed, ie the included between the surface 1 16 and the lever 1 15 angle γ1 is increased in γ2 (Fig. 2c). When erecting the lever supports 1 15 with its end 124, the auxiliary straps 1 13 and deflects them laterally, ie the auxiliary straps 1 13 are deflected substantially perpendicular to its longitudinal direction away from the ski 101 away. In the auxiliary straps 1 13 thus the tensile stresses 131 are generated due to the pressing force 130 of the push rod 103 by the push rod 103 the lever 1 15 erects. Since the auxiliary straps 1 13 are anchored to each of the two longitudinal ends 1 17 and 120 on the ski body 102, such a lateral deflection without substantial stretching of the auxiliary straps 1 13 is only possible if the distance between the anchors of the longitudinal ends 1 17 and 120 is reduced. Such a reduction of the distance forces the ski 101 in the steering range 1 12 in a longitudinal deflection. In this case, a force component 136 of the pulling force 131, which is substantially perpendicular to the surface 16 of the ski 101 in the region of the anchoring of the longitudinal ends 17, acts. Since the auxiliary straps 1 13 protrude from the ski 101 on an upper side 16 of the ski or are anchored to the surface 16, the deflection of the steering region 12 takes place at a Setting up the lever 1 15 in a positive sense. Due to the arrangement of the anchorages of the longitudinal ends 1 17 and 120 of the auxiliary straps 1 13 on the ski body 102 of the bent steering portion 1 12 is also lifted from a pad of the ski 101.

The deflection in the steering range 1 12 is in the embodiment of Fig. 2a-c so by increasing the tension due to a deflection transverse to the auxiliary straps 1 13 of the ski 101 away at both longitudinal ends 1 17 and 120 at the longitudinal ends 1 18 and the first 19 of the steering range 1 12 anchored to the ski body 102 auxiliary straps 1 reaches 13.

The auxiliary straps 1 13 can be z. B. have a bias, which z. B. can be regulated. Depending on requirements, eg. B. Can the skier or ski discipline, then the bias of the auxiliary straps 1 13 can be adjusted. For this purpose, a further (not shown) clamping device may be provided which z. B. via an operating unit allows the skier to change a bias in the auxiliary straps 1 13. A bias of the auxiliary straps 1 13 but is not essential. Such a tensioning device can also be provided in other embodiments in order to make the ski more versatile and to ensure adaptability to the respective requirements.

FIG. 3 shows a partial view of a steering region 212 of a ski 201 according to the invention with a transmission device 204 with a rocker 214. The rocker 214 is rotatably mounted on a ski body 202 about an axis F arranged perpendicular to a ski surface 216. The longitudinal position of the axis F thereby limits the steering area 212 at a rear longitudinal end 219 in a direction towards a rear ski end (not shown). The rocker 214 has with respect to the axis F a longer 215.1 and a shorter arm 215.2, with which a push rod 203 (arm 215.2) and an auxiliary belt 213 (arm 215.1) are each articulated in a region of their longitudinal ends 208 and 220 respectively. The push rod 203 corresponds largely to the push rods 3 and 103 of the previous figures, wherein the push rod 203 is not centrally located with respect to a direction transverse to a longitudinal direction of the ski 201, but laterally offset. In a rear region of the ski 201, the push rod 203 is supported with a further longitudinal end on the ski body 202 (not shown). The auxiliary belt 213 is anchored in a region at the front longitudinal end 217 in the front region of the steering region 212 on the ski body 202. In particular, the longitudinal position of the anchored longitudinal end 217 forms a front longitudinal end 218 of the steering portion 212. The auxiliary belt 213 can be loaded substantially to train, but can also be loaded on pressure, so that by the transmission device 204 with rocker 214, a forced coupling of the push rod 203 with the Auxiliary belt 213 and thus results with the front of the ski.

If a pressure force 230 of the push rod 203 now acts in the direction of a front ski end 209, the pressure force 230 is transmitted via the rocker 214 into a pulling force 231 in the auxiliary belt 213. The pulling force 231 engages the ski body 202 via the longitudinal end 217 anchored in the ski body at the front end of the steering area 212 and thus exerts a force in the direction of the rear ski end on the front ski area. Thus, in particular the steering region 212 is deflected and lifted the ski 201 in the steering area 212 of a pad. Due to the different length of the two arms 215.1 and 215.2 it is achieved that the tensile force 231 is smaller in terms of amount than the pressing force 230, a displacement of the Hilfsgurts 213 compared to the displacement of the push rod 203 but larger.

FIG. 4 shows a partial view of a steering region 312 of a further embodiment of a ski 301 according to the invention having a transmission device 304 with a transmission 314. The transmission 314 comprises two gear wheels 315.1 and 315.2 which are rotatable about an axis G and H perpendicular to a ski surface 316 Ski body 302 are stored. The common longitudinal position of the axes G and H thereby limit the steering range 312 at a rear longitudinal end 319 in a direction to a rear ski end (not shown). The ski 301 has a push rod 303, which largely corresponds to the push rods 3 and 103 of Figures 1 and 2.

The transfer device 304 has two auxiliary straps 313.1 and 313.2, which are anchored in a region at the longitudinal ends 317.1 and 317.2 in a front region of the steering region 312 on the ski body 302. In particular, the longitudinal position of the anchored longitudinal ends 317 forms a front longitudinal end 318 of the steering region 312. The auxiliary straps 313 are symmetrical from a longitudinal axis of the ski 301 laterally spaced apart, arranged substantially parallel to the ski body 302. The auxiliary straps 313 are substantially loadable on train, but can also be loaded under pressure, so that a forced coupling of the push rod 303 with the front region or the steering region 312 of the ski 301 results through the transmission 314.

The gear wheels 315 are arranged on the ski body such that they can cooperate on the one hand with a region at a rear longitudinal end 320.1 and 320.2 of the auxiliary belts 313 and with a region at a front longitudinal end 308 of the push rod 303. In this case, regions at the rear longitudinal ends 320.1 and 320.2 of the auxiliary straps 313.1 and 313.2 overlap in the longitudinal direction with the front region of the push rod 303. The auxiliary straps 313 engage with respect to a plane which is perpendicular to the ski surface 316 and includes the longitudinal axis of the ski 301, from the outside to the gear wheels 315, while the push rod 303 with respect to the axes G and H on an opposite side, d. H. with respect to the plane from the inside, engages the gears 315. The push rod 303 and the auxiliary straps 313 can interact positively and / or positively with the gears 315. In particular, the gears 315 may be formed as gears, wherein the auxiliary straps 313 and the pressure pads 303 then have corresponding teeth which can engage in the gears.

A pressing force 330 in the push rod 303 forward is thus translated via the gears 315 in a tensile force 331 in the auxiliary straps 313, which acts on the anchorage of the longitudinal ends 317 on the front ski area, in particular on the front longitudinal end 318 of the steering portion 312.

FIG. 5a shows a top view of a ski 401 according to the invention with a ski body 402 and a tension belt 403. FIG. 5b shows a corresponding side view of the ski 401 and FIG. 5c and d show further possible arrangements or guides of the tension belt 403 on the ski body 402, wherein FIG the corresponding plan views has been omitted. FIGS. 5 a - d are highly schematic and are intended to illustrate the guidance of the tension belt 403 with respect to the ski body 402. The tension belt 403 of the ski 401.1 in FIGS. 5a-d is anchored with its longitudinal ends 408 and 405 to the ski body 402 in each case in an area at the front 408 and at the rear ski end 406 with anchors or support points 407.1 and 407.2. The tension belt 403 is anchored with its front longitudinal end 408 to an upper side 416.1 of the ski body 402 and guided in a steering area 412.1 in the longitudinal direction to the rear ski end 406 above the ski body 402 up to an opening 414.1, which is formed in the ski body 402. The opening 414.1 is open on the upper side 416.1 and on an underside 416.2 of the ski body 402 and is arranged centrally on the ski body 402 transversely to the longitudinal direction. The tension belt 403 passes from the steering area 412.1 from top to bottom through the opening 414.1, where it passes z. B. at the edges of the openings of the opening 414.1 on the ski body 402 is supported. The steering area 412.1 is thus essentially limited to the front by a longitudinal position 418 of the anchoring 407.1 and to the rear by a longitudinal position 419 of the opening 414.1. The tension belt 403 is then guided below the ski body 402 in the longitudinal direction to the rear ski end 406 to form another opening 414.2, which is arranged closer to the ski end 406 at a longitudinal position 420. The tension belt 403 is guided through the opening 414.2 again to the top 416.1 of the ski body 402, wherein he z. B. is supported on the ski body 402 at the edges of the openings of the opening 414.2. The length region, which is delimited by the longitudinal positions 419 and 420 of the two openings 414.1 and 4141.2, forms a control region 410.1 of the ski 401. From the opening 414.2, the tension belt 403 on the upper side 416.1 of the ski 401 or above the ski body 402 becomes an area guided at the rear end of the ski 406, where it is anchored with its rear longitudinal end 405 via the anchoring 407.2 to a longitudinal position 421 on the ski body 402. The length region between the longitudinal positions 420 and 421 thus forms a further, second steering region 412.2 of the ski 401.1. In the case of a positive deflection of the ski body 402 in the control region 410, the tension belt 403 is tensioned due to the deflection, ie a tensile force 430 is generated in the tension belt 403. The pulling force 430 along the tensioning belt 403 then acts via the anchoring points 407.1 and 407.2 as tensile forces 431.1 and 431.2 on the regions at the ski ends 409 and 406. Due to the displacement of the tension belt 403 relative to the ski body 402 associated with the force effect, the result is thus Pulling forces 431.1 and 431.2 a bending or bending of the ski 401 in the steering areas 412th The arrangement shown in FIG. 5c on a ski 401.2 largely corresponds to that shown in FIG. 5b, but the tension belt 403 is guided from the first opening 414.1 on the underside 416.2 to an area at the rear ski end 406 and there on the ski body 402 at the support point 407.2 is anchored. Thus, a control region 410.2 is formed by the length region of the ski 401.2 which lies between the longitudinal position 419 of the opening 414.1 and the longitudinal position 421 of the support point 407.1 at the rear end 406 of the ski. In this embodiment, in addition to the opening 414.1, there is no further breakthrough in the ski body 402, and the steering area 412.1 corresponds to the steering area of the ski 401.1.

In the arrangement of a ski 401.3 shown in FIG. 5d, the tension belt 403 is guided below the ski 401 from an area at the front ski end 409 to the rear opening 414.2. The tension belt 403 is anchored on an underside 416.2 of the ski 401.3 at the longitudinal position 418 via the support point 407.1 on the ski body 402. The area between the longitudinal position 418 of the support point 407.1 and the longitudinal position 420 of the opening 414.2 thus forms a control area 410.3 of the ski 401.3. There are no further breakthroughs on the ski body 402 available. The tension belt 403 is guided through the opening 414.2 from the underside 416.2 to the upper side 416.1 of the ski body and there above the ski body 402 to a region of the rear ski end 406, where the tension belt 403 is anchored to the support point 407.2 on the ski body 402. The length region between the longitudinal position 420 of the opening 414.2 and the longitudinal position 421 of the support point 407.2 thus forms a rear steering area of the ski 401.3 and corresponds to the steering area 412.2 of the ski 401.1.

6a shows a plan view of a further embodiment of a ski 501 according to the invention with a ski body 502 and a compression belt 503 designed as compression belt and a transmission device 504. Figure 6b shows a corresponding side view of the ski 501. The ski 501 is in a forward direction in a designated direction lying area 521 bent by a driving support, as is the case with conventional skis.

The push rod 503 is arranged in a rear region 510 of the ski 501. The push rod 503 is in the longitudinal direction of the ski 501 and centered with respect to one direction arranged transversely to the longitudinal direction, such that a rear longitudinal end 505 of the push rod 503 ends at a rear end 506 of the ski body 502 offset by a designated shift range 540 to the top 509 of the ski 501 out, so that the push rod 503 in a shift to the rear end 506 of Skis 501 does not stand above this. In an area at the front longitudinal end 508 is the push rod

503 at a support point 507.1 connected to the ski body 502 or anchored to this. Over the remaining length of the push rod 503, this is displaceably guided in the longitudinal direction relative to the ski body 502 (guide device not shown), so that the area 510 forms the control area 510. In the control area 510 of the ski 501, the push rod 503 is supported in particular with a deflection of the ski 501 via the support point 507.1 on the ski body 502 relative to this displaceable. With a positive deflection of the control area 510, d. H. For example, when the rear ski 506 is lifted from a base relative to a central region of the ski 501, a shift of the rear longitudinal end 505 of the push rod 503 from a rest position 51 1 relative to the ski body 502 toward a rear longitudinal end 506 of the ski 501 out. The rest position 51 1 is defined by the position of the longitudinal end 505 when no external loads act on the ski 501 and is offset at a distance 540 from the rear end of the ski 506 to the top 509 of the ski 501.

The transfer device 504 extends substantially the entire length of the ski 501. In the illustrated embodiment, the transfer device comprises

504 essentially a train-loaded auxiliary belt 513, which is arranged in the control area 510 below the ski body 502 or below a longitudinal axis of a ski longitudinal deflection of the ski body 502. The auxiliary belt 513 preferably has a slight, essentially vanishing, elasticity. However, it is quite possible embodiments in which the auxiliary belt 513 is designed dynamically and has an inherent elasticity.

The auxiliary belt 513 is in a front area in two front end portions 513.1 and

513.2 split. The auxiliary belt 513 thus has two front longitudinal ends 517.1 and 517.2, with which it anchored to an upper side 516.1 of the ski body 502 and in a steering region 512 in the longitudinal direction to the rear ski end 506 above the Ski body 502 led up to the length of the support point 507.1 openings 514.1 and 514.2 in the ski body 502 out. The openings 514.1 and 514.2 are open on the upper side 516.1 and on an underside 516.2 of the ski body 502 and are arranged on the ski body 502 transversely to the longitudinal direction on both sides of the push rod 503 or the support point 507.1. The openings 514.1 and 514.2 are formed in the ski body 502 and are preferably not shown further layers of the ski 501 such. B. a sliding coating on the underside 516.2 or a lining of the ski 501 at the top 516.1 covered. The openings 514.2 and 514.2 preferably pass into a guide channel (not shown) on the underside 516.2 of the ski body 502, into which the auxiliary belt 513 is guided in the direction of the rear longitudinal end 506 or to a rear opening 514.3. However, the openings do not need to pass through the ski body 502. To guide a tension belt can also be easily formed a guide channel below the neutral fiber in the ski body, wherein the guide channel is open at its longitudinal ends at the top of the ski body, so that guided in the channel tension belt can enter or emerge from the channel. The person skilled in this case also directly further execution options are clear as the leadership of the tension belt in the board body can also be done in other ways to produce a traction in the tension in a deflection of the ski body in the control area.

The auxiliary belt 513 passes from the steering region 512 from top to bottom through the openings 514.1 and 514.2, whereby it passes, for example, through the openings 514.1 and 514.2. B. at the edges of the openings of

Breakthroughs 514.1 and 514.2 is supported on the ski body 502. The steering area 512 is thus substantially forward through a longitudinal position 518 of the anchorages

517.1 and 517.2 and limited to the rear by a longitudinal position 519 of the openings 514.1 and 514.2.

The two end regions 513.1 and 513.2 of the auxiliary belt 513 are brought together below the ski body 502 in the region of the openings 514.1 and 514.2 in a rear region 513.3 of the auxiliary belt 513. The auxiliary belt 513 is of the apertures 514.1 and

514.2 guided below the ski body 502 in the longitudinal direction of the rear ski end 506 to the further opening 514.3, which is arranged in the region of the rear longitudinal end 505 of the push rod 503 in a longitudinal position 522. The auxiliary belt 503 is guided through the opening 514.3 back to the top 516.1 of the ski body 502, where it is connected to a rear longitudinal end 520 at a support point 507.2 fixed to the rear longitudinal end 505 of the push rod 503. The length range which is limited by the longitudinal positions 519 and 51 1 of the openings 514.1 / 514.2 and the rear longitudinal end 505 of the push rod 503 thus corresponds substantially to the control area 510 of the ski 501.

In the case of a positive deflection of the ski body 502 in the control area 510, on the one hand the rear longitudinal end 505 of the push rod 503, which is supported on the support body 507.1 on the ski body 502 and is displaceably guided above the ski body 502, is displaced from the rest position 51 1 backwards. Thus, with respect to the ski body 502, a compressive force 530.1 is generated in the pressure belt 503, which is directed towards the rear end 506 of the ski 501. In the auxiliary belt 513, which is connected to the support point 507.2 fixed to the rear longitudinal end 505 of the push rod 503 with this, the displacement of the push rod 503 has a tensile force 530.2 result, which is also directed to the rear end 506 of the ski 501. The pulling force 530.2 is thus rectified by the pressing force 530.1, which is generated in the push rod 503. Since the auxiliary belt 513 is guided substantially in the entire control area 510 below the ski body 502, it is additionally tensioned by the deflection of the ski 501, whereby the total tensile force 530 is increased at the end portion 513.1 of the auxiliary belt 513 against the force 530.1 along the belt 503. The deflection in the control area 510 is to a certain extent felt twice: on the one hand by the push rod 503 above the ski body 502 and on the other hand by the tension belt 513 below the ski body 502.

The pulling force 530.2 along the auxiliary belt 513 then acts via the anchoring points 517.1 and 517.2 as pulling forces 531.1 and 531.2 on the position 518 on the front ski 509. Due to the displacement of the auxiliary belt 513 relative to the ski body 502 associated with the force effect, this results from the tensile forces 531.1 and 531.2 bending the ski 501 in the steering area 512.

In a modification, the auxiliary belt 513 in the steering area 512 by an additional

Support member 515 may be supported, for example, to improve an angle of attack of the tensile forces 531 on the ski ends 509 in the position 518 (dashed lines in Fig. 6b shown). The support member 515 may be passively formed as a simple guide shoe, but also act as an active support element (for example, analogous to the support member 1 15 of Figures 2a-c) by a variable arrangement relative to the ski 501, the tensile forces 531 in the auxiliary belt 513 further increase and / or redirect.

Like the previously described embodiments, the last described is to be regarded as a schematic and illustrative example and can be modified in many ways without departing from the scope of the invention. In particular, the auxiliary belt can be designed, for example, as a simple tension belt with only two longitudinal ends, one each at the front and at the rear longitudinal end of the ski. It is conceivable in this case, for example, that the push rod in the region of a single front opening in the ski body has a longitudinally formed slot through which the centrally guided on the ski auxiliary belt passes, after he from the breakthrough on the ski body from the bottom to the top of the ski body is guided. Thus, it can be achieved, for example, when the auxiliary belt is centrally guided over the entire length of the ski, that the auxiliary belt can protrude out of the ski body in the area of the central push rod and the push rod nevertheless remains displaceable. In other embodiments but also, for example, two or more push rods and only a central auxiliary belt be present, the push rods in this case, for. B. with respect to the longitudinal axis of the ski on both sides of the Hilfsgurts can be arranged. It is understood that regardless of the number of push rods and a plurality of auxiliary straps can be present and if necessary, the push rod or push rods in one end, for example, in each case two longitudinal ends can pass or (analogous to the auxiliary belt 513 of Fig. 6a-b) ,

7a shows a plan view of a further exemplary embodiment of a ski 601 according to the invention with a ski body 602 and a pressure belt 603 designed as compression belt and a transmission device 604. Figure 7b shows a corresponding side view of the ski 601. The ski 601 is in a direction of travel lying forward portion 621 in the resting state of a driving support, as is the case with conventional skis. A steering region 612 of the ski 601 extends from a front boundary 618 in the region of the ski tip 609 in the direction of the rear ski end 606 beyond the bent-up region 621. Towards the rear end of the ski 606, the steering area 612 is delimited at a longitudinal position 619 of a passage 614.1 for an auxiliary belt 613 in the ski body 602.

The push rod 603 is disposed in a rear portion 610 of the ski 601. The push rod 603 extends from a longitudinal position 615 in an area behind the rear longitudinal boundary 619 of the steering area 612 substantially to the rear ski end 606. The push rod 603 is arranged in the longitudinal direction of the ski 601 such that a rear longitudinal end 605 of the push rod 603 at the rear End 606 of the ski body 602 by a designated shift range 640 to the top 609 of the ski

601 ends, so that the push rod 603 does not protrude beyond this on displacement to the rear end 606 of the ski 601. At the longitudinal position 615, the push rod 603 is anchored in an end region at a front longitudinal end 608 via a support point 607.1 on the ski body 602. The push rod 603 is arranged offset from a central axis J of the ski body 602 transversely to the central axis J in parallel. The push rod 603 is arranged in an inner half 623 of the ski 601, wherein "inside" a region is designated, which faces the further ski when using the ski 601 or a pair of skis.

Over the length of the push rod 603, this is displaceably guided in the longitudinal direction relative to the ski body 602 (guide device not shown), so that the length region 610 forms the control region 610. In the control region 610 of the ski 601, the push rod 603 is supported in particular with a deflection of the ski 601 via the support point 607.1 on the ski body 602 relative to this displaceable. With a positive deflection of the control region 610, the rear longitudinal end 605 of the push rod 603 is displaced from a rest position 61 1 relative to the ski body

602 toward a rear longitudinal end 606 of the ski 601 out. The rest position 61 1 is defined by the position of the longitudinal end 605 when no external loads act on the ski 601 and is offset at a distance 640 from the rear end of the ski 606 to the top 609 of the ski 601. The transfer device 604 extends essentially over the entire length of the ski 601. In the illustrated embodiment, the transfer device 604 essentially comprises a train-loadable auxiliary belt 613, which is located in the control region 610 below the ski body 602 or below a longitudinally neutral longitudinal axis of the ski Ski body 602 is arranged. The auxiliary belt 613 preferably has a slight, essentially vanishing, elasticity.

The auxiliary belt 613 is in a front end portions 613.1 in the steering portion 612 in the longitudinal direction, d. H. guided substantially parallel to the central axis J above the ski body 602. A front longitudinal end 617 of the auxiliary belt 613 is anchored to the front boundary 618 of the steering area 612 of an upper side 616.1 of the ski body 602. The auxiliary belt 613 passes through the passage 614.1 at the rear longitudinal end of the steering area 612 to the underside of the ski body 616.2. The opening 614.1 is open on the upper side 616.1 and on an underside 616.2 of the ski body 602 and is formed longitudinally in front of the push rod 603 on the ski body 602. The breakthrough

614.1 is formed in the ski body 602 and, as in the examples described above, is preferred by further layers of the ski 601, not shown, such as, for example, the ski 601. B. a sliding coating on the bottom 616.2 or a covering of the ski 601 on the top 616.1 covered. The opening 614.1 preferably merges into a guide channel (not shown) on the underside 616.2 of the ski body 602, in which the auxiliary belt 613 is guided in the direction of the rear longitudinal end 606 or to a further, rear opening 614.2. The rear opening 614.2 is arranged in the region of the rear longitudinal end 605 of the push rod 603 in a longitudinal position 622.

The auxiliary belt 603 is guided through the opening 614.2 again to the upper side 616.1 of the ski body 602, where it has a rear longitudinal end 620 at a support point

607.2 fixed to the rear longitudinal end 605 is connected to the push rod 603. The length region, which is delimited by the longitudinal positions 615 and 61 1 of the support point 607.1 or of the rear longitudinal end of the push rod 603, corresponds essentially to the control region 610 of the ski 601. With a positive deflection of the ski body 602 in the control area 610, the rear longitudinal end 605 of the push rod 603, supported on the support point 607.1, is displaced from the rest position 61 1 backwards. Thus, with respect to the ski body 602, a compressive force 630.1 is generated in the pressure belt 603, which is directed towards the rear end 606 of the ski 601.

In the auxiliary belt 613, which is connected to the support point 607.2 fixed to the rear longitudinal end 605 of the push rod 603 with this, the displacement of the push rod 603 has a pulling force 630.2 result, which is also directed to the rear end 606 of the ski 601. The pulling force 630.2 is thus rectified by the pressing force 630.1 generated in the push rod 603. Since the auxiliary belt 613 is guided substantially in the entire control area 610 below the ski body 602, it is additionally tensioned by the deflection of the ski 601, whereby the total tensile force 630 at the end portion 613.1 of the Hiifsgurts 613 against the force 630.1 along the belt 603 is increased. The deflection in the control area 610 is to a certain extent felt twice: on the one hand by the displacement of the push rod 603 above the ski body 602 (belt) and on the other hand by the stretching of the trainable Hiifsgurts 613 below the ski body 602 (transmission device). The total force 630 is thus composed by the compressive force 630.1 of the push rod 603 and the additional force generated in the auxiliary belt due to an expansion.

In the presently described embodiment, the ski 601 is divided from the front ski end 609 to the rear end 619 of the steering section 612 along the central axis into two sections 625.1 and 625.2. The section 625.1 is arranged in the inner half 623 of the ski body 602, while the section 625.2 is formed in an outer ski half 624. "Outward" also refers to the arrangement of two skis when used by a skier. The two sections 625.1 and 625.2 are divided by a slot 627, wherein the slot 627 extends along the central axis to the longitudinal position 619. The slot 627 may have a certain width, so that the two sections 625.1 and 625.2 are spaced transversely to the longitudinal direction J from each other. The two sections 625.1 and 625.2, however, may also substantially abut one another directly, ie a width of the slot 627 substantially disappears.

With the slot 627 or with the division of the steering range in the two sections

625.1 and 625.2 it is achieved that the ski body 602 can be deflected differently in the steering area 612 as a function of a position transverse to the longitudinal axis J. In particular, sections 625.1 and 625.2 can be bent largely independently of one another. Depending on the amount or direction transmitted by a belt or the transmission device 604 tensile force on the respective

Section 625.1 or 625.2, a corresponding deflection can be achieved in the respective section 625.1 or 625.2. In particular, a deflection can the

Needs or requirements are adjusted.

In the illustrated embodiment, the total pulling force 630 of the auxiliary belt 613 via the anchoring point 617 acts as a pulling force 631 at the position 618 on the portion 625.1 of the steering portion 612. The tensile forces 630 and 631 correspond to each other in terms of magnitude largely (apart from friction losses or the like). Due to the displacement of the auxiliary belt 613 in relation to the ski body 602, which is associated with the force effect, the tensile forces 631 thus result in an upward or downward bending of the ski body 602 in the section 625.1. The section 625.2 decoupled by the slot 627 largely with respect to a longitudinal coupling from the section 625.1 does not experience a tensile force which could cause a deflection. The section 625.2 therefore remains largely in its rest position. FIG. 7b shows the ski 601 with bent or bent section 625.1 and section 625.2, which is in the rest position.

The turning of the ski 601 into a cornering thus results in a bending of the steering area 612 in an inner section 625.1 due to a longitudinal deflection in the control area 610. Due to the division of the steering area 612 into an inner and an outer section 625.1 and 625.2, when cornering along an inner edge 635 on the underside 616.2 of the ski body 602 in the steering area, two acting edges result: on the one hand, the inner edge of the ski body 602 and second, an inner edge 636 of the outer portion 625.2 resulting from the slit 627. At a deflection of the inner portion 625.1 thus arises the inner edge 635 of the ski body 602 in the steering area 612 a smaller edge radius, while at the inner edge 636 of the outer portion 625.2 no additional dynamic curvature in addition to the static curvature of the bent portion 621 results. As has been shown so that the steering of the ski 601 can be significantly improved in cornering. In addition, with advantage over the belt system or the transmission device 604 for the bending of the section 625.1, only a significantly lower force is expended than if the ski 601 in the steering area 612 had to be bent over the entire width. The skilled person is immediately clear that a subdivision of the steering range 612 in several sections in principle in all embodiments is conceivable and can form an advantageous embodiment as required.

In contrast to other embodiments shown, the push rod 603 of FIGS. 7a and 7b is not arranged symmetrically on the ski. However, the asymmetric arrangement is not a requirement for the presently described embodiment with divided into sections 625.1 and 625.2 steering area 612. Rather, the push rod 603 as in previously described embodiments, the ski body 602 may be arranged. The present specific embodiment serves as an illustrative example of a further possibility of arranging a push rod on a ski according to the invention. In particular, with the transmission device according to the invention, the tensile force on the steering area can likewise be transmitted asymmetrically to different sections of the steering area in embodiments with, for example, centrally arranged or several push rods. The tensile force can also be in the sense of e.g. 1a and / or 6a are transmitted symmetrically to a split steering range according to FIG. 7a.

FIG. 8a shows a functional sketch, which shows in sections a steering region 712 with deflecting device 704 of a ski body 702 of a ski 701 in a rest position 722 without external loads (pulled through) and in a position 723 in which the

Ski body 702 is deflected in the steering region 712 due to a tensile force 731, which results from a force 730 along a tension belt 703. To generate the tensile force 730 in the tension belt 703, reference is made to previously described and illustrated examples and embodiments. The tension belt 703 can in this case in the sense of a Hilfsgurts for Transfer device 704 belong or else directly to the belt formed according to the invention on the ski for generating the force effect.

The transmission device 704 comprises in the representation of FIG. 8a a lever element

715, which is connected at a right angle δ fixed to the ski body 702. The lever member 715 is schematically formed as an elongate member having a first 715.1 and a second longitudinal end 715.2, the lever member 715 having a base

735 of the lever member 715 forming the first longitudinal end 715.1 in the steering area 712 am

Skikörper 702 is anchored. At a distance 736 from the base 735, a front engages

End region 703.1 of Zuggurts 703, so that due to the tensile force 731 with respect to the base 735, a torque on the lever member 715 and thus also on the firmly connected to the lever member 715 ski body 702 results in the steering area 712.

Due to an intended flexibility of the ski body 702 at least in the steering area 712, the ski body 702 undergoes a deflection as a result of the torque, so that the ski body 702 is brought from the rest position into the bent-up position 723. The instantaneous axis of rotation, with respect to which the torque acts, is on the one hand not stationary with respect to the ski body 702 and on the other hand can not be defined in a simple way, since the deflection does not take place about a fixed axis but includes a flexible deflection of the ski body 702. Therefore, the torque acting on the lever member 715 does not work for each deflection state with respect to the base 735, but strictly speaking only in the first moment of the force action 731, as long as no deflection has yet occurred.

While the embodiment of FIG. 8a shows a schematic diagram, a more concrete implementation of a lever element 815 of a transmission device 804 on a ski 801 according to the invention is shown in FIG. 8b. The lever element 815 is largely L-shaped, with a shorter arm 815.1 of the L-shape forming a base 835 of the lever element 815. The longer arm 815.2 is disposed substantially parallel to and in the longitudinal direction of a top 816.1 of a ski body 802 of the ski 801, with the longer arm 815.2 extending from the base 835 to a rear ski end (not shown). The lever member 815 is fixedly connected to the base 835 in a steering area 812 with the ski body 802, the longer arm 815.2 is arranged at a distance 837 from an upper side 816.1 of the ski body 802 and has a rear, free end 836.

The ski 801 in this case has a pressure belt 803 which is supported on a support point 807 on the ski body 802 and which is arranged on an upper side 816.1 of the ski body 802. At a rear longitudinal end of the pressure belt 803, not shown, the pressure belt 803 is connected to the auxiliary belt 813. The system belt 803 / auxiliary belt 813 and their interaction corresponds largely to the belt systems illustrated in FIGS. 6a and 6b as well as 7a and 7b.

An auxiliary belt 813 of the transmission device 804 designed as a tension belt engages in the area of the free end 836 on the lever element 815 and is guided in a largely perpendicular direction to the ski body 802 to a passage 814 in the ski body 802 and through it to an underside 816.2 of the ski body 802. The auxiliary belt

813 is guided such that a force 830 along the auxiliary belt 813 in a force

831 is transmitted to the free end 836 of the lever member 815 such that the force 831 is directed toward the ski body 802 and the free end 836 of the lever member 815 to

Ski body 802 is pulled out.

A length 838 of the longer arm 815.2 essentially determines the effective lever arm for a torque, which acts on the lever element 815 with respect to the base 835 due to the tensile force 831 acting on the lever element 815. Since the lever member 815 is fixedly attached to the ski body 802, the torque thus generated transmits to the ski body 802 and thus results in a deflection of the ski body 802 from a rest position 822 (solid line) to a bent position 823 (dashed) result.

The L-shaped design of the lever member 815 thus allows a comparatively long lever arm (length 838) to be provided on the ski 801 in such a way that only a small overall height results (spacing 837 plus a thickness of the longer arm 815.2). Overall, thus, a lever element 835 of the transmission device 804 can be created with great leverage, which is particularly well suited for a ski 801, since the sun reached low height allowed an embodiment of the transfer device 804, which rises only slightly above the surface 816.1 of the ski body 802.

The formation of a transmission device with L-shaped lever element can therefore also for further, z. B. how various of the embodiments of the invention described above represent a preferred variant.

The steering range of a ski according to the invention can be significantly longer than the bent-up portion, as known from conventional skis. Likewise, in the case of a divided into largely independent sections steering range, z. B. with a slot as shown in Fig. 7a and 7b, the sections extend as far as desired to the rear end of the ski. "Anyway, far back" understood here in the context of an even more meaningful embodiment of the invention, so that a deflection of the steering range is even possible. In principle, the steering range can also be shorter than the bent-up area.

It should also be noted that the arrangements shown and described depending on the requirements of the ski can be largely combined with each other. There are z. B. conceivable embodiments in which 2, 3 or more pull straps are arranged on the ski. In particular, z. B. an arrangement according to FIG. 5c with central, d. H. with respect to a direction transverse to the longitudinal direction of the ski central arrangement with two laterally symmetrical outer arrangements of another Zuggurtführung be combined. But there are also other combinations of Zuggurten conceivable, which can form advantageous embodiments of an inventive ski. Likewise, one or more transmission devices may be provided for transmitting the tensile force to the steering area, which cooperate with one or more straps, wherein the straps may be tension or compression straps or a combination of the two.

In a further embodiment of the invention with a tensile belt capable of tensile load, it is also possible to support the tension belt in the steering area by means of a support element. The support element is then z. B. in one or in all steering areas of the ski between a surface of the ski body and the tension belt arranged such that the tension belt is supported on the support member against the ski body. This ensures, on the one hand, that the angle of attack of the tensile force on the anchoring of the tension belt on the ski body changes can be, for. B. so that the tensile force acts at a larger angle on the ski body. In addition, with such a support element but also a bias in the tension belt can be generated or adjusted. Is the support element z. B. adjustable in height, the tension in the tension belt can be increased with an increase in the height of the support element. Likewise, an increase in the voltage can be achieved if a support element is displaced with a constant height in the longitudinal direction to the respective, adjacent to the steering area breakthrough. The displacement raises the tension belt and increases the tension in the belt. If a support element is present, it may be caused by the skier z. B. be changeable or adjustable to z. B. make before the trip Skiläufer- and / or discipline-specific default settings. But it is also possible to achieve the adjustability of the bias in the tension belt without support element in other ways, for. B. by an adjustable shortening or lengthening of the Zuggurts or by other known measures for generating a static tension in a belt. In principle, the tension belt can comprise a band, rope or any other element capable of being subjected to tension.

All described embodiments are to be understood as illustrative examples of embodiments of the invention and may be extended or modified. It should be noted in particular that the representations of the figures only serve to give an idea of the functional principle of the ski according to the invention and do not describe a detailed embodiment.

A possible modification of the illustrated embodiments relates to the auxiliary straps or the tension belt, which need not necessarily be guided freely suspended, as shown in the figures. It is readily conceivable that the belts in the steering range z. B. in a sheath or on the ski body, if this is possible without limiting the functionality of the invention. In particular, it should be noted that in an arrangement z. B. a belt above or below a ski body and a partial arrangement of the belt is included in the ski body. In particular, it is conceivable in all embodiments that straps and transmission devices and other construction elements are arranged under a sweeter shell of the ski, so that the elements are not visible from the outside. Next, a structure of the ski body is largely freely selectable without restrictions. In particular, the ski body may include conventional, largely static systems of upper and tension belt, as they are well known from the prior art. The ski body can also z. B. have a layer structure with or without core, but may in principle be formed in one piece. For use in a ski according to the invention, there are essentially no limits to the design of the ski body.

Basically, in all embodiments conceivable that the improved effect z. B. on the steering range, the tensile force or other forces occurring to be directed or supported by other construction elements, transferred and / or deflected. In particular, the tensile force can be deflected to the front steering range depending on the requirement or for optimization by additional elements.

In one embodiment of the ski with a rocker is conceivable that two rockers are provided, in which case there is also another pressure belt and another auxiliary belt on the ski. The rocker shown in Fig. 3 can then be supplemented by a further rocker, so that in each case a pressure belt and each an auxiliary belt attack on each rocker. The other pressure belt and the other auxiliary straps are arranged symmetrically on the ski, z. B. mirror image of the arrangement shown in Fig. 3 of the first straps. In particular, in an embodiment with equal rocker arms is conceivable that the two rockers are scissor-like mounted on the same joint.

In summary, it should be noted that the invention provides a snow gliding board, in particular a ski, which offers the possibility of dynamically adapting the deflection behavior to the loads. In particular, a steering region of the snow gliding board can be deflected or deflected as a function of a deflection in a control region, wherein a transmission device transmits a force along a belt of the ski according to the requirements to a steering region of the ski.
