Description

The subject of the present invention is a gliding or roller sports device which consists either of two skis of known type for gliding on snow or skiing, or of two juxtaposed roller boards with front and rear at least one roller or a wheel for rolling on a fixed, inclined roadway on skis, with the skis or skateboards are movably coupled together.

As is known, modern skis, so-called carving skis, are heavily fitted. This means that viewed in plan view, the width in the foremost area, called a bucket, can be more than fifty percent greater than in the middle area, and the rearmost part, the ski end, again can be almost as wide as the bucket. Symmetrical to their longitudinal central axis, modern skis so on both sides of a pronounced, concave radius formed, resulting in the aforementioned, strong sidecut. On this sidecut the flexing (bending) of the ski is exactly matched, which, viewed from the side, by the weight of the driver and the forces generated in the curve is generated. Another component is the torsional strength of the ski in the curve, which is particularly important for heavily waisted skis. The interaction of these different components also plays a very important role.

The main purpose of this special training of carving skis is to give a new feel to the curve, in which the skis, as soon as they are put on the edge, somehow follow a curve of their own in such a way that this curve as on a rail is driven in contrast to conventional, only slightly waisted skis, which is slipped around the curve so to speak. The perfect carving means that not only is there no loss of speed in the curve, but even additional speed is generated, whereas the traditional slipping around the curve with low-waisted skis always means a slowdown of the ride.

The carving conveys, as I said, a new, very dynamic driving experience on snow, which has given the ski sport and thus the ski industry new impetus. On the other hand, it has been shown that this new type of ski can also have disadvantages. For example, cornering at high speed inevitably increases the risk of collision on heavily frequented ski slopes. This increased tempo in bends and the fact that the ski is no longer slipping but held on a rail can result in significantly higher forces acting on the rider's legs, resulting in a significant increase in joint, muscle injury and ribbons leads. Above all, the knee is severely affected.

Particularly serious is the vulnerability to injury among young drivers who are still growing. In addition, it has been shown that heavily fitted skis make it almost impossible to correct driving errors, which increases the frequency of falls and thus the risk of injury. After all, learning to ski with carving skis is more difficult than using low-waisted skis, especially the very easy grade exit, which can also lead to more frequent falls and thus injury, which in turn can result in potential new winter sports customers. Industry to be enthusiastic about this sport.

The object of the present invention is, on the one hand, to continue to ensure the above-described fascination of carving skiing, but on the other hand to eliminate as far as possible the disadvantages and dangers mentioned. Another object of the invention is to realize the same basic idea, that is, the carving-like feel when gliding on skis for driving with two trolleys.

If we achieve this goal by two carving skis or skates of known type are connected by at least one coupling system such that the skis or skateboards can still be moved longitudinally and changed in their edge position or lateral inclination, but only one given, geometrically clear Preferably, this coupling system is designed so that the longitudinal center line of both skis or skateboards in their basic position on flat ground - if their tips, shoes and ends are at the same height - are aligned parallel to each other, and that this parallel alignment of the longitudinal centerlines also then preserved when the ski or a skateboard is advanced, for example, in the oblique drive or in the curve. In addition, the mentioned coupling system is preferably designed so that the changing of the lateral inclination of a ski or a roller board inevitably causes a certain same or different inclination of the other skis or skateboard, that is, the inclination of the two skis or skateboards is coordinated. Thus, in the case of skis, the edge position of a ski - from the flat, full support of the entire tread in the basic position (falling line) to the extreme edge position in the steep slope or in the curve - inevitably causes the same change in the edge position of the other ski, or one with a different measure. Or in other words: The coupling system causes the upright angle of one ski and that of the other ski is always synchronously changed in the same direction, from the flat, full edition of the tread in the Degree exit to pronounced edge position in steep terrain or strong cornering of the driver. Likewise, in the case of two side-by-side roller boards, their inclinations are coupled and thus coordinated. One can therefore also speak of an always parallel alignment of the running surfaces or board surfaces or an angle-synchronized movement.

There are already known coupling systems which pursue similar goals. But none has prevailed on the market so far. In an already known type, the mentioned deficiencies are only insufficiently eliminated, so that the additional technical effort on the ski or skateboard not worthwhile. Other, also known solutions are complicated and therefore prone to failure, heavy and expensive, which is why they could not gain a foothold in the market. So in the state of the art about the DE 10 2004 063031 A1 known, which discloses a Aufkantsystem for movably connecting two skids or skis. Thus, the two skis are guided in parallel and the tilt is coupled with a parallelogram of control bars. The system consists of a connecting device arranged in front of the binding region and behind the binding region, with a spring travel which varies the respective connecting length and at the same time with damping elements. US 2003/0155726 A1 shows a sliding board arrangement with two ski-like boards and one shoe binding, wherein the two sliding boards are connected to each other with a connecting device in different versions. This connection means, for example, allows the shoes on each sliding board to be displaced back and forth relative thereto. The distance between the sliding boards can be increased by spring loading, and in one embodiment, the horizontal angle of the sliding boards to the shoes can also be changed. In no case, however, is it about a coordinated, ie coupled tilting of the sliding boards. FR 2 592 314 shows a device for easier learning of skiing. Connecting elements can be used to make two skis into a kind of monoski, which is then helpful in learning to drive in a closed manner. CH 661 875 shows a Parallelgrammanordnung before and behind the ski binding of skis, so that the skis are displaced in the longitudinal direction against each other, and their tilt is coupled. The parallelogram arrangement is clamped by means of screws laterally with the skis and it always needs tools to them to assemble and disassemble. DE 28 06 883 shows an auxiliary device for skis, which also couples the parallel displacement of the skis in the longitudinal direction and their common tilting. This auxiliary device is bolted firmly to the skis. And US 3,907,320 Finally, shows a ski trainer, through which the two skis are connected at any point with each other, so that their maximum distance is limited. So that the skis equipped with such connecting devices can be transported in railway gondolas, where the skis with their sliding surfaces directed towards each other must be plugged into a vase-like square receptacle, such connecting devices are a hindrance and make transport impossible. Also, for transport on a car roof ski racks, it is usually necessary to put together the skis in this way that the skis with the sliding surfaces are directed towards each other. Also for compact care in apartments or hotels, it is best if the skis sliding surface can be put together on sliding surface to To save space. For this purpose, however, the connection means, no matter how they are designed, can be solved quickly. For re-use then these connection devices must again be very easy, quick and safe to be mounted on skis or racks, which does not want to resort to tools. The prior art proposals give no instructions for this and offer no solutions.

With the present invention, which is essentially explained by means of skis for gliding on snow, a solution is to be offered, which eliminates all the disadvantages and dangers listed, also is simple in construction and therefore reliable under all conditions. In addition, a technical solution was sought, which has optimal conditions to be perfectly integrated in terms of design in the ski pair, also has a low weight and makes a cost-effective mass production possible. The latter are decisive factors for a rapid dissemination of the invention on the market and thus also for economic success. The present invention is intended to facilitate the learning of carving skiing and reduce the number of accidents. It is understood that in principle the same coupling can be realized for two side by side arranged skateboards and thus the same effect for rolling on a solid surface or inclined roadway is possible. The sequence of movements and the driving feeling for the initiation and extension of curves are very similar.

The object is achieved by a gliding or rolling sports device consisting of a pair of skis for gliding or two skateboards for rolling boarding with bindings for the driver's shoes, the left ski or the left skateboard with the right ski and the right skateboard is hingedly connected by a coupling system, so that in a longitudinal displacement of a ski or a roller board with respect to the other ski or the other skateboard, the skis or skates are guided parallel or approximately parallel to each other, and the lateral tilting of the two skis Rolling boards is coordinated by the coupling system such that the angular change of the two individual skis or skateboards is coupled to the base, characterized in that on the top of each skis or roller board two of a Hand snap and releasably on the ski or skateboard about their vertical axis pivotally attachable bearing heads are available, further that in adjacent skis or skate the left and right opposite bearing heads are connected to one or two trusses or one or two legs, the ends on different heights are pivotally mounted in the bearing heads and thus form a parallelogram with these bearing heads, so that the edge layers of the two skis or skateboards are coupled together. This construction thus works with bearing heads on the skis, which can be latched by hand and releasably secured to the ski about its vertical axis pivotally . At these bearing heads, the connecting beams or legs are articulated, so that the skis are slidably coupled relative to each other in the longitudinal direction, and also an edge of the skis is coupled, which are achieved by the design of the length, shape and the articulation points of the trusses or legs can, that the canting of the respective curve outer ski turns out to be stronger than that of the inside ski.

In the drawings, advantageous embodiments of the invention are illustrated with reference to skis and described in detail below and their benefits will be explained.

A non-inventive gliding device is to ever mount a coupling system in front of and behind the ski binding area on the skis or to integrate into these, as in the FIGS. 1 to 11 It is of course possible to connect the coupling systems very close to the binding with the skis or even to integrate parts of the ski binding. It is also intended to an embodiment in which the front coupling system is connected at the top of the ski tip and the other at the rear of the ski, with the skis, it may be useful in this case, also the tail - aufzubiegen as the ski tip - like this is already the case with certain types of skis or snowboards today.

Tests have shown that an assembly of the embodiment according to the Fig. 1 to 11 in the area between ski binding and ski tip resp. The end of the ski works well. A first embodiment will be described in detail hereinafter.

According to Fig. 1 are the coupling elements 100a and 100b, which are identical in construction and operation, depending fixed in the rear and in the front of the ski on this, for example by means of screws or special adhesive. For this purpose, first the base plates 110 according to 8 and 9 attached to the skis. Of course, it is also possible that the ski manufacturer offers a special ski on which these base parts 110 are already preassembled - possibly integrated in the ski. The pre-assembled coupling elements 100a and 100b according to Fig. 1 are then attached to the journal 112 of the base parts 110, as shown Fig. 6 Viewing the whole from the side, without skis, shows. By means of a screw or a locking pin, which has, for example, a ball latch, the coupling elements 100a and 100b secured against lifting up, but a rotation of the rotating body 120 is ensured in both directions. This makes it possible that the skis according to Fig. 11 can be moved away from each other in the longitudinal direction, the longitudinal centerlines of both skis always remain parallel.

Of course, it would be technically possible, for example, by different training, especially the effective length of the two coupling elements 100a and 100b to ensure that the skis while in basic position according Fig. 1 are parallel, but at a longitudinal displacement form an increasing angle to each other, being thought in the first place to a slight drift apart of the ski tips, for example, to achieve a special curve effect.

To change the edge position according to Fig. 10 to allow the coupling elements 100a, 100b each consist of two mutually independently movable trusses 130,140, which are so pivotally mounted in the rotating bodies 120, that they geometrically each form a parallelogram and thus are able to always a same size resp. equal small edge position of the ski to ensure the same direction.

It is thus not possible, for example, to place the running surface of the left ski outwards on the outer, left edge and at the same time the running surface of the right ski on the outer, right edge. The same applies vice versa: It can not be both treads are placed on the inner edges simultaneously. This feature contributes significantly to the fact that with the sliding sports device according to the invention less driving errors can be made and that learning the correct carving technique is not only easier, but also safer.

The fact that the above-mentioned parallelograms are not recognizable as such has the following reason, which arises from the Fig. 10 evident. While the connection of one cross member 130 between the joints 135 and 135 'is physically direct, the other cross member 140 is not guided directly from hinge 146 to hinge 146' but yoke-like in a higher position than that in the home position Fig. 1 to 5 identical to that of the traverse 130, so that a proper ground clearance between the skis is guaranteed and can not accumulate snow on the trusses while driving. The screws 145 support the crossbars 140 on the discs 121, wherein an arcuate recess 144 in the flange portion 143 of the cross member 140 ensures that the lateral Pivoting movement for the purpose of changing the edge position in a limited area is possible.

As already mentioned, the entire system can be designed so that the crossbars 140 together with their bearing parts can be removed quickly and easily and stowed, for example, in the backpack, e.g. by using ball-lock type quick-release pins of known type instead of screws. This makes it possible to transform the device at any time into two normal skis, which can move independently of each other, be it for a change or, for example, for overcoming an incline in the step of stairs or burrs.

It has already been suggested that it is thought to integrate the coupling elements directly into the ski binding, whether in the stand plate commonly used today, which is arranged between ski and ski binding, or directly in the ski binding elements, i. on the one hand the toe and on the other hand in the automatic heel. Such an embodiment may be useful insofar as it is expected that the institutions responsible for this will therefore not require a safety bond, because when falling always both legs remain connected to the device, as is the case with the snowboard:

The accident experts have come to the conclusion that it is more dangerous if only one foot is released when falling with the snowboard, as if both feet remain connected to the board. Thus, if the sliding sports device according to the invention can be equipped without safety binding, this binding will be very simple in its construction and correspondingly simple would be the integration of the coupling parts in the binding elements or the underlying base plate.

The lower weight and lower manufacturing cost of a non-triggering ski binding would compensate for the additional weight and cost of the clutch system, making the unit - if any - just a little more expensive and heavier than a pair of carving skis Safety binding and stopper. In this context, the very important statement was made that a non-triggering ski binding would not pose a risk of incorrect setting of the triggering forces. In a holistic way, this would increase the security of the system and reduce both the liability risk and the time spent by the sporting goods retailer or lessor. This could significantly contribute to the market success of the new device.

Experiments have shown that it is possible with shorter skis to form only one coupling element as a parallelogram with two connecting beams, the other hand as a simple, movably connected to the skis Traverse, as by the FIGS. 28 and 29 is pictured. As a result, a simplification can be achieved, which has a positive effect in terms of weight, cost and appearance.

A further simplification in the aforementioned sense is to achieve at particularly short mounting intervals of the coupling elements when the rear coupling element only the lower, yoke-like Traverse and the front only the upper, physically directly acting traverse is provided. The parallelogram is then made by an interaction of the rear with the front clutch, as is made Fig. 23 is recognizable.

The FIGS. 16 to 32 show how the trusses are formed as rods with a round cross-section and can be connected in a very simple and solid way with the rotatably mounted on the skis holding bodies 320a and 320b. These images illustrate what is described above, namely the operation of the visible, direct connection by means of the upper cross member 331 and the indirect, yoke-like connection by means of the second, lower cross member 341. The main advantage of such a solution is that the height of the for the synchronized movement of the treads essential parallelogram mechanism can be kept very low, without restricting the angular range of the running surfaces (Aufkantwinkel).

In a gliding device according to the Fig. 24 and 25 Both coupling elements 300 are connected to the spacer plate between ski and ski binding. This has the great advantage that no reinforcement measures on the skis are necessary, as in the solutions according to Fig. 1 to 23 probably indispensable. In addition, the assembly is facilitated, especially if the binding stand plate factory can be prepared for the attachment of the bearing parts of the coupling elements. It is even possible that the bearing parts 310 of the coupling elements 300 are integrated directly into the base plates 355 by the binding manufacturer.

From the Figs. 27a and 27b It can be seen how it would be possible to connect the coupling elements 300 directly to the release plates 370 of a safety bond. Since these plates separate with a heavier fall together with the ski boots 38 of the skis 30, so it is possible to apply the inventive coupling system also in combination with a tripping bond.

As the Figures 26A As shown in Figure 26B, it is also contemplated to connect only one coupling system 300 - preferably the rear - directly to the release plates 370 but the front to the skis 30. This makes it possible in the simplest way to ensure that the front interconnected skis - after triggering the bond - do not drive away and so to speak stop themselves. In this way can be dispensed with ski-stopper, which saves costs and weight. That it is also possible to move the joints 235 of the trusses 231, 241 eccentrically inwards, show the Fig. 12. to 15 , This allows a particularly large angular freedom of the treads can be achieved, as in Fig. 14 is pictured.

Another way to connect the trusses with the skis, the FIGS. 28 and 28 Here is a coupling element 320, which has two trusses 331, 341, mounted behind the ski center, while the second coupling element is movably connected to the ski tips and only a single cross member 335 has.

Such an arrangement at the top can be advantageous for the assembly, wherein factory special training of the tips is essential, for example, characterized in that the normally provided on the ski tips tip protection has a special design. For the appearance of this arrangement may be advantageous because the graphic design of the front ski area is not affected. In addition, the traverse on the ski tip can reduce the risk of threading in slalom rods or even eliminate. How the connection with the ski tips, for example, can be solved technically, make the FIGS. 30 to 32 in detail dar. That the coupling elements can be integrated directly into the base plate between ski and binding, has been explained earlier. The FIGS. 33 and 34 represent a particularly useful, technical solution of this principle. The bent steel bar 470 is mounted between ski 40 and base plate 455, for which the base plate has corresponding channels on its underside. The outside of the base plate 455 bent up steel bracket 470 forms the bearing axis for the bearing parts 471 and 475, which are rotatable and the bearings 472 for the trusses 431 and 441 form. Because the coupling elements are very close to each other, it is expected that - as explained earlier - two trusses 431, 441 at the rear and only one traverse 441 'at the front are required. Such an arrangement of the inventive coupling system has the advantage that it can be easily mounted without additional processing and / or reinforcement of the skis and that it does not affect the graphic design of the ski surfaces. In addition, the traverses between the ski boots are barely noticed. For example, what a technical solution to this arrangement might look like, and how it works when the treads are flanked FIGS. 35 to 38 shown in cross section.

Of particular importance is the principle of operation according to the FIGS. 39 to 42 insofar as it is ensured here that the skis always have the same lateral distance in the case of a longitudinal displacement of one ski with respect to the other, for example in the truss travel or in the curve, as in straight-line or fall-line travel. This is according to FIG. 40 achieved in that only one bearing part 525a and 520b are firmly connected to the ski, and that these bearing parts are not rotatable, but only the SchwenkPunkte for the two traverses 531, 541 at the rear and the individual traverse 535 at the front.

At the respective opposite points, the trusses are pivotally mounted in largely identical bearing parts 520a and 525b, these latter bearing parts not being fixedly connected to the skis, but rather to longitudinally displaceable rails 570a and 570b. These rails are longitudinally displaceable in the base plates 555a and 555b and mounted very smoothly. In this way, it is possible to move one ski relative to the other in the longitudinal direction, without the width spacing of the skis changing, in contrast to all the embodiments shown and described hereinbefore. It is expected that such a behavior of the sliding sports device according to the invention will be desired by certain drivers or even selected by the specialist trade as a standard design.

The FIGS. 41 and 42 represent an even simpler design of the functional principle just described. It is expected that it is sufficient especially for very short skis, if only two bearing elements 520a and 520b are provided, the one 520b fixed to the ski, the other with the longitudinally movable rail 570 is connected. In this way, weight and cost can be saved, the assembly is simplified and the appearance wins.

It is of course also thought of a simplified embodiment of the coupling system, in which no longitudinal displacement of one ski with respect to the other is possible, but only a synchronous edge of the running surfaces always in the same direction. The ski tips thus always remain at the same height. This is especially possible with short skis and is expected to make it easier for beginners to learn. This can save costs and weight. It is also possible that thereby driving technical advantages, for example, on very hard or in deep snow snow can be achieved.

In the embodiment according to the FIGS. 43 and 44 is the coupling system in the specially designed for this purpose plate 650, 680th integrated, that the coupling elements 620, 620 'together with their base elements 625, 625' can be easily assembled and disassembled without the use of tools. For this purpose, the base plates 680, 680 ', for example, at their outer end regions U-shaped and have lateral holes 629, 629', in which spring-loaded balls engage in a known manner. These balls are in the extensions 626, 626 'of the clutch base plates 625. 625' mounted so that they may protrude, but can not fall out upon disassembly of the coupling elements. This disassembly is carried out in a known per se fact that is pressed by hand on these balls until they are pushed so far that the base part 625 of the coupling member 620 can be pulled out of the U-shaped recess. The assembly takes place by simply pushing the base part 625 into the U-profile, in which case the balls are automatically pressed into their guide bores until they find the hole 629 at the intended location and lock the base part in the longitudinal direction. The function of the spring-loaded balls can also be achieved in that the slide part 626 of the base part 625 made of flexible plastic and is designed so that it can take over the locking and unlocking functions in a known manner, for example in the sense of belt fastener couplings on modern backpacks ,

In order to prevent the outer, U-shaped end portions of the base plates filled with disassembled coupling elements with snow, ice or other material, a simple filling part, which has the shape of the base plate 625, are inserted into the profile opening, wherein the lock and Unlocking can be done analogously in the manner described above. By such a measure, it is also ensured that the front and rear end portions receive a formal perfect appearance after disassembly of the coupling elements.

The operation of the coupling system is identical to that of the embodiments described earlier. The rotary member 631 and 641 pivotally mounted. The automatic heel 660 and the toe 670 also known type form the safety bond, which today Usually mounted on the base plates 650, 680 to ensure the necessary distance between ski boot and snow pad.

Of course, the function of the stand plates can also be taken over by specially trained base elements of the binding parts 660,670. In this case, these base elements can be formed so that the assembly and disassembly of the coupling elements 620,625 analogous to the description of FIGS. 43 and 44 is possible. The advantage of an integration of the coupling system in the base plates of the bindings or directly in the binding elements is that no additional installation on the ski is necessary and also the design of the ski surface in front of and behind the binding is not affected.

Experiments have shown that a particularly advantageous embodiment of the inventive sliding sports device is that the longitudinal displacement of the skis is limited against each other, for example, such that a stop element on the bearing parts 110,110 'ensures that one ski 10a relative to the other 10b in the longitudinal direction only a distance that is substantially half to as long as the sole of a medium-sized ski boot, which corresponds to a length range of about 150 to 350 mm.

A further development of this embodiment would be that this displacement distance is not fixed but individually adjustable, for example, by the fact that the abovementioned stop is designed to be displaceable or as an adjustable contact point.

Of course, it is also possible, instead of a stop of the type described to produce the limitation of the longitudinal displacement in other ways, for example by at least one pulling member, which is arranged between truss system 100a, 100b and a skifesten element, such as the binding, the limiting distance of this Zugorganes can be made adjustable.

Practical tests have also shown that it may be advantageous to design at least one of the cross members 331, 341 so as to ensure limited flexibility, which may be advantageous when driving on hard snow, in that the vibration of one ski is damped and not on the one other skis is transferred. This flexibility resp. Damping property can be achieved, for example, that at least one of the truss elements 331.341 consists of relatively thin steel wire or of a suitable plastic. It would also be possible to install a limited elastic zone in the middle region of the cross members 331, 341, e.g. by means of a plastic part. This plastic part could also be designed so that it can simultaneously serve to change the length of the truss element, for example in the known manner by means of left-right thread.

Tests have also shown that attachment of at least one truss element 300 (FIG. Fig. 9 ) on the ski boot can be advantageous. A possible solution of this embodiment could be to attach at least one pair of bearing members 310a, 310b to the rear of the ski boot shaft such that the bearing heads 320a, 320b would rotate about an axis substantially parallel to the longitudinal center line of the skis. In the event that two truss elements 300 were attached to the ski boot, one could be mounted at the rear of the ski boot shaft as described and the other at the front of the ski boot. It is also conceivable that a truss element is mounted on the ski boot and the other on the ski or on a plate attached to the ski.

FIG. 45 shows an embodiment in which two bearing heads 310a, 310b are slidably fixed on a rail with respect to their position. In FIG. 46 This arrangement is shown from above in a top view on the ski. It can be the area on the ski behind or before the binding. The two bearing blocks are displaceable along the rail and clamped at any point in the sliding area by means of the screws shown.

FIG. 47 shows an embodiment in which each a single bearing head 310 is slidably mounted on a guide steel with a dovetail profile, as indicated by the double arrow. The bearing head 310 can be fixed in any position in the sliding area by means of screws. Here, this displaceable bearing head 310 is located behind the rear binding on the ski. In FIG. 48 the arrangement is positioned in reverse order on the back of the ski. The sliding bearing block 310 is attached here at the very end of the ski.

Structure and operation of a further embodiment according to FIGS. 45 and 46 will be described in detail below. According to Fig. 45 For example, the coupling element 100 is fastened to the skis 10a and 10b, for example by means of screws or special adhesive. For this purpose, the base plates 110a, b are first mounted on the skis. Of course, it is also possible that the ski manufacturer offers a special ski on which these base parts 110a, b are already preassembled or even integrated in the ski. The pre-assembled coupling elements 100a and 100b according to Fig. 45 are then attached to the journal 112 of the base parts 110. By means of a screw or a plug pin 125a, b, the coupling elements 100a and 100b secured against lifting up, but a rotation of the rotating body 120 is ensured in both directions. This makes it possible for the skis 10a, b to be displaced away from one another in the longitudinal direction, the longitudinal center lines of both skis always remaining parallel. Of course, it would be technically possible, for example, by different training or arrangement of the two coupling elements 100a, b to ensure that the skis are parallel in the basic position, but form at a longitudinal displacement at an increasing angle to each other, primarily due to a slight drift apart the ski tip is thought, for example, to achieve a special curve effect, respectively. to achieve different radii of the skis. Experiments have shown that it is possible with shorter skis, only the one coupling element 100 as a parallelogram with two connecting beams 130,140 form, the other hand as a simple, movably connected to the Skis Traverse. As a result, a simplification can be achieved, which has a positive effect in terms of weight, cost and appearance.

To change the edge position according to Fig. 48 and 49 allow the coupling elements 100 each consist of two independently movable trusses 130,140, which are pivotally mounted in the rotating bodies 120, that they form a parallelogram geometrically considered and thereby are able to always edge up both skis in the same direction guarantee. If the truss parts 130, 140 are the same length and are mounted vertically one above the other in the rotary body 120, both skis are always bent up at the same angle. This simplest arrangement is not shown in the figures. As from all FIGS. 45 to 54 can be clearly seen, the trusses are 130,140 different lengths and slightly offset relative to the solder on the ski longitudinal central axis 135a, b and 145a, b. This ensures that the Talski is tilted in the oblique travel on the slope respectively the bow-shaped ski in the curve stronger than the mountain ski respectively the bow inside ski in a curve. This effect is the more pronounced, the more the skis are tilted up, so progressively increasing.

When two coupling elements 100, 100 'are used, e.g. one in front of and one behind the binding area, it may be expedient to provide a smaller angle change in the rear coupling part 100 than in the front coupling part 100 '. As a result, additional driving technology effects can be achieved. This can be achieved by different arrangement and length of the trusses 130,140 at the rear coupling element 100 'relative to the front 100'.

The coupling parts 100 may be formed so that this angle is variable, for example, in that the trusses 130,140 according to FIGS. 51 and 52 are variable in length and can also be stored in different positions of the rotating body 120. As already mentioned, the entire system can be designed such that the crossbars 130, 140, together with their rotary bodies 120 (FIG. Fig. 47-49 ) or 520 ( Fig. 56 ) can be removed quickly and effortlessly and stowed, for example, in the backpack, for example by using quick-release pins with ball locking known type instead of screws 125a, b, such as in FIG. 55 shown. This makes it possible the sliding sports equipment according to the invention at any time to transform into two normal, completely independently movable skis, be it for a change or, for example, to overcome a slope in the staircase or bone step.

The installation of both coupling elements behind the binding area according to FIGS. 52 and 53 has technical, aesthetic and practical advantages. The technical advantages are that the modern ski in the rear area is thicker than before the binding and so the subsequent assembly is easier. Aesthetically, the system looks better because nothing is visible in the area before the binding and thus the graphic design of the ski surface is not affected. A practical advantage not to be underestimated is the fact that the coupling parts can be fixed on the ski itself if a user wants to use the skis in a conventional manner, ie not coupled. For this case, it must be ensured by technical means of known type that the bearing parts can be loosened and plugged in a simple manner.

The FIG. 54 shows a further embodiment in which only a single coupling system is used, which is preferably connected to the front of the ski or integrated with this. It is expected that the purpose of the invention will be achieved in this way as far as possible with the positive effect that the cost and weight are lower, and that a very experienced driver in this way driving advantages over a double clutch system can be offered, for example in that for certain curves a shearing position of the skis can be generated. In addition, the sideways climb on a slope can be facilitated.

Another way, the rotor 120 and 420, including the trusses quickly and effortlessly remove and reassemble can, shows the FIG. 55 , Here takes over the pivot lever 422,424 which is rotatably supported by means of the axis 423, the function of the screw 125a, b. When the upper leg 424 of this lever is pressed against the spring pressure of the rubber member 428 from above, moves the lower leg 422 of the lever away from the bearing pin 412, and the tooth 425 is released from the groove 413 of the journal.

The Figure 57 represents a solution in which the two coupling systems 600a, 600b only consist of one traverse. It is the front element 600a, the "upper" and the rear element 600b, the "lower" Traverse the previously shown versions with upper and lower traverse available and leave out the other. It is expected that this results in an identical or at least similar effect, as if both coupling elements are equipped with two trusses. This would result in a significant simplification, which would have a positive impact on weight and cost.

Same idea as at Fig. 57 is also the subject of the embodiment according to the Figures 58 and 59 , In both coupling systems 700a, 700b, only one individual traverse is provided, with the rear element 700a being the "upper" and the front element 700b the "lower" traverse. In addition, this arrangement has the same features, which in the description of the FIGS. 52 and 53 were mentioned.

Yet another variant, each with only one traverse per coupling system provide the Figures 60 and 61 Here is at the ski tips the upper, and further back on the ski only the lower Traverse provided. In the embodiment according to FIGS. 62 and 63 It is about the special training of mounted on the ski tips Traverse. This has the additional function to reject the skis of possible obstacles. The idea is primarily to slalom poles, to avoid a "threading". Of course, other shapes are also conceivable here, for example a pronounced triangular shape. The FIGS. 64 to 66 show a particularly advantageous possibility to store the front cross member at the ski tips in a simple way such that both a rotation about an axis parallel to the longitudinal centerline of the ski axis and a rotation about an axis perpendicular thereto is possible, which is for the inventive device is essential. Fig. 64 shows the top view, Fig. 65 the view from the side and Fig. 66 shows a view viewed from the rear, wherein the tread of the skis is cut in the front area. Analogous to the solution according to Fig. 56 For example, the traverse can be quickly and easily removed by pressure on the ball stud 1022.

The tests with prototypes have shown that it is advantageous both in terms of handling (risk of pinching the fingers when wearing the skis) and the formal appearance, both brackets 130,140 of the truss elements 1100a, 1100b on the same side of the bearing heads 120 as close as possible to each other to store. This is what the Figures 67 to 69 which at the same time also show how the skis, when displaced longitudinally, Fig. 67 ) in the inclined position ( FIGS. 68 and 69 ) stay parallel. This arrangement of the truss brackets 130,140 and their operation in the longitudinal displacement of the skis is illustrated with the detailed representations according to the FIGS. 70 to 74 , In the FIGS. 71 to 74 In addition, the unlocking buttons 2122 can be seen, the task of which will be described below.

The FIGS. 75 to 79 again represent the embodiment according to the figures just described, but also show the functioning of the edge of the skis from the flat basic position ( Fig. 75 ) in the pronounced oblique travel and curve position ( Fig. 78 and 79 ). The upright angles of both skis always have, so to speak, the same angle to the underlay in terms of both direction and angle. As a result, dangerous driving errors, also called edge errors, which can often lead to momentous falls, turned off.

The operation of the above-mentioned unlocking buttons 2122 goes out of the Figures 80 to 82 especially, from Fig. 81 , In principle, it is a spring bolt element of known type, the spring-loaded mandrel engages in the driving position of the device in a groove 113 of the journal 112. By pulling the unlock button of the mandrel disengaged, and the entire bearing head 120 can be removed together with the truss brackets 130.140 from the ski, which is advantageous in many respects, for example, for repair and service work on the ski or if a driver skis completely normal without Wants to drive connecting trusses. Also for transport on the car roof or with the gondola, a simple disassembly device may be important.

The arrangement of the inventive truss system according to the Figures 67 to 69 comes in principle in the FIGS. 83 to 88 for use. But new is the locking or unlocking system. Both the bearing head 3120 and the release lever 3122 are designed differently than in the previously described versions. In the overview, the principle goes from the Figures 83 to 85 , wherein the arrangement and operation of the truss brackets 130,140 has already been described earlier. It is essential to the operation of the locking and unlocking of the bearing head 3120, which by the FIGS. 86 to 88 is clarified.

Both in section according to Fig. 88 as well as in the plan view according to Fig. 87 It can be seen that the bracket 3122 engages with two inwardly directed pins 3122-1 and 3122-2 in the groove 3113 of the bearing journal 3112, for the purpose of locking the bearing head 3120 analog Fig. 81 , These two pins 3122-1,3122-2 are also pivot bearings for the whole bracket 3122, and they are under spring load, because the made of elastic material bracket 3122 has a bias in the assembled state. How very clear Fig. 86 As can be seen, the bracket 3122 has in the region of said pivot points a surface 3122-3, which cooperates with the oblique control cam 3120-1 as follows. When the stirrup 3122 is pulled up, the surface 3122-3 intends to move downwardly, but this may be due to the oblique cam 3120-1 only when the stems 3122-1 and 3122-2 move outwardly and thus also leave their engagement from the groove 3113. This results in the unlocking effect in a simple, reliable and cost-effective manner. The locking takes place, so to speak, automatically, when the bearing head 3120 is slipped over the journal 3112 from above with some pressure.

Based on tests, it is thought to form the traverses 130,140 so that they take a damping function, for example when driving and swinging on hard snow. This can be achieved by virtue of the fact that at least some of the crossbars 130, 140 have an elastic region, for example of a suitable plastic or of a thinner dimensioned steel part.

Finally, attention should be drawn to the possibility of restricting the range of longitudinal displacement of the two skis against each other, e.g. by means of suitable stops. Because in tests it has been noticed that it is harmful in the inventive system when the skis are shifted too much in the longitudinal direction against each other up to the so-called default position. In other words, it is optimal, when driving and swinging the skis in the longitudinal direction only little to move against each other, so as to achieve a better lateral support.

So far, this new gliding and rolling sports device has been presented with different versions for skiing on snow. However, this truss system can equally be used on a device which can be used on an inclined roadway, for example such that two elongated skateboards of known type are equipped before and behind the central area, each with a truss system, analogous to the application for sliding skis on snow. In the central area of the skateboards, a binding, similar to a ski binding, can be provided, or the driver is - as is customary with roller boards - only loose on the two boards, which of course takes some getting used to than the use of a binding. With such a double-skateboard similar maneuvers can be driven on the road as sliding on snow, especially since such skateboards are provided with self-steering undercarriages, which allow a cross position of the chassis by pure weight transfer. In FIG. 93 a single conventional skateboard is shown as seen from below. One recognizes the two pairs of rollers, which are each mounted pivotably about the vertical axis. If on the right side in this illustration, which is indicated by an arrow, is placed from above increased pressure compared to the left side, so swing the two axes against each other, against a built-in spring force, as shown by the two curved arrows.

In FIG. 94 the roller sports equipment is seen from the front. It consists of two conventional roller boards, which are coupled together with a truss system, such as with the one in the FIGS. 51 to 53 presented for the skis. This construction then forms a coupled pair of skis. If the two skateboards are not inclined, as in FIG. 94 shown, so are the roles for a Aligned straight ahead. But if the two Rollbetter or the Rollski pair loaded on one side more with pressure - which is done by shifting the weight, so the roller axes of the two front pairs of rollers are swung toward the side with the greater pressure, and the rear not visible here Roll pairs just swung in the opposite direction. You therefore travel with this Rollskis along a circular arc, similar to how one with carving skis along a circular arc "carvt". These sports equipment or Rollskis can be equipped with bindings for shoes, or even enter and ride without such bindings with sports shoes. For braking separate facilities can be provided. So foot pedals can press a brake pad on the road, or brake pads can be operated on the rollers by hand via Bowden cables, or even more brake solutions can be considered.
