Description

The invention relates to a gliding board, in particular a snowboard, consisting of two skis, in particular touring skis, and fitting parts for joining the touring skis to one another.

When touring it has been shown that the snow conditions do not always make it possible to ski with the touring skis or make it very difficult to ski. Snowboards are much more suitable for this, but they do not allow ascent without outside help, for example ski lifts. For this reason, the desire has arisen to create a sports device which is constructed at least in two parts, the two parts being usable as skis, in particular touring skis, and in the assembled state as snowboards.

In the known snowboards composed of commercially available skis, such as are apparent, for example, from DBGM 89 03 154, there is the problem that the waist radii of skis and conventional snowboards are so far apart that the assembled snowboard cannot be used for the cut swing. The tail radius is about 40 m for skis, while that for snowboards is about 8 to 12 m.

The object of the present invention is, starting from commercially available skis, in particular touring skis, to provide a gliding board, in particular snowboard, which, in the assembled state, corresponds to the customary requirements for snowboards with regard to the waist radii, and the skis nevertheless have their disassembled state Maintain properties as skis, in particular touring skis, in particular with regard to waist radii and hardness.

This object is achieved by the means specified in claim 1.

Through the use of a tensioning device, by means of which the skis can be tensioned against one another in the middle area with deformation in the transverse direction, the gliding board assembled in this way receives tailing radii on both sides, as can be found in the usual snowboards. Since the skis are kept at a distance from one another at least in the region of their ends, forces which act on the individual skis when cornering are so great that they no longer act hard because they are now parts of a large-area snowboard in which the middle part is missing or consists of one part, possibly several parts, which can only absorb small forces, so that the forces must now be absorbed by the two skis, which are otherwise also distributed to the middle part of a snowboard.

In order to be able to set the waist radius as desired without great effort, it is advantageous if, according to a further embodiment of the invention, a selectable distance between the skis can be set by the fitting parts and that the waist of the sliding board or snowboard with at least partially remaining distance between the skis is adjustable. This allows enough play to be left between the skis and the middle section from the start in order to be able to subsequently change the waist radius.

If, in a further embodiment of the invention, the fitting parts in the area of the ski tips and in the area of the ski ends comprise clamps or sleeves and connecting rods penetrating the clamps or sleeves, the connecting rods preventing a height difference between the connected skis when inserted into the clamps however, the mutual distance between the individual skis can be freely adjusted, so that a secure connection between the two skis that can be quickly established is achieved in a simple manner without the adjustability of the waist radius being hindered.

According to the invention, a simple possibility of being able to adjust the distance between the skis is that the clamps are designed as clamps and can be clamped onto the connecting rods.

Another possibility for the adjustability of the distance is that fixed or adjustable stops are provided on the connecting rods. While the clamps can be changed continuously, which is also the case with the adjustable stops, the fixed stops on the connecting rods must be replaced if the distances are to be changed.

Although the skis can in principle be connected to one another at a distance from one another, it is expedient if, in a further embodiment of the invention, a one-part or multi-part, transverse or longitudinally divided middle part can be used between the two skis, with the exception of those assigned to the ski tips and the ski ends Regions has a shape, on the basis of which when the ski rests with the two end regions on the middle part, a gap which widens from the two ends towards the center of the ski remains.

This gap is necessary to allow the skis to be braced so that the desired waist radius can be set. It is advisable to choose the shape of the middle section so that the gap is closed when the skis are tensioned, i.e. that the skis have the desired waist radius when they are in contact with the middle section. This creates a gliding board or snowboard with a continuously closed gliding surface.

Usually, due to the waist radius of the skis, it is sufficient if, according to a further advantageous embodiment of the invention, the middle part in the front area is adapted to the shape of the ski tips and in the rear area to the shape of the ski ends, and that the area in between runs parallel to one another Has limitations to by bracing the touring ski until it is completely in contact with the middle section to maintain the required waist radius.

If, on the other hand, due to special wishes with regard to the driving properties of the gliding board or snowboard, this waist radius is not yet sufficient, then it is expedient if, according to another embodiment of the invention, the middle part in the front region of the shape of the ski tips and in the rear region of the shape of the ski ends is adapted, and that the area in between is waisted. This enables an even stronger waist to be adjusted.

A particularly simple measure for connecting the middle part to the skis according to the invention is that the middle part has fitting parts for receiving the connecting rods.

In order to connect the skis and the central part in a simple manner in their central area so that there is no difference in height between these parts, plug connections can be provided in a further advantageous embodiment of the invention in the central area of the skis and the central part, which have a height difference in the assembled state prevent between the connected parts, but allow the mutual distance between the ski and the middle part to be

In order to obtain a visually appealing exterior, the fitting parts can be embedded in the skis and / or in the middle part in a further embodiment of the invention.

If simple clamps or sleeves are provided on the skis that do not allow them to be clamped to the connecting rod, it can be advantageous in a further embodiment of the invention if the connecting rods are fastened to the central part. Losing the connecting rods in the disassembled state of the sliding board is hereby excluded.

If the middle part is sturdy enough, it can serve as a spacer for the skis, especially touring skis.

Depending on the hardness or stiffness of the skis, there may be deformations in the event of strong tension by the tensioning means, such that the skis deflect upwards in relation to the horizontal support plane, resulting in a convex tread because the outer edges deflect upwards. In order to prevent this phenomenon or to consciously set a certain, be it convex, flat or concave tread, in a further embodiment of the invention the connecting rods can be bent or kinked at the areas assigned to the skis. When the gliding board, in particular snowboards, is braced by means of the tensioning means, when the forces leading to the deformations described above occur, the bent regions are deformed, whereby they elastically counteract the deformation forces. With an appropriate choice of the kink angle of the outer areas of the connecting rods and corresponding alignment of these areas, any sliding surface shape of the snowboard can be set, from a convex to a flat to a concave surface.

The tensioning means can preferably consist of a turnbuckle.

The skis, in particular touring skis, can also be arranged offset to one another in the longitudinal direction, as a result of which an asymmetrical gliding board or snowboard is obtained.

The gliding board or snowboard shown in the drawing comprises two commercially available skis 1, in particular touring skis, and a central part 2, which essentially serves only as a filler, both in the symmetrical configuration according to FIGS. 1 to 17 and in the asymmetrical configuration according to FIG. which are connected by fitting parts 3 and 4 so that a height difference between the interconnected parts is prevented, while a clamping means designated 5 braces the skis against the central part and thus holds the individual parts together in the lateral direction without additional holding means in the transverse direction being necessary would be.

The fitting parts 3, as can be seen in particular from FIGS. 7 and 8, comprise base parts 6 and 7 which are screwed on by means of screws 8 in the edge region of the skis and the middle part. The base part 7 carries a plug pin 9 which engages in a bore 10 in the base part 6 in the assembled state of the individual parts. This avoids a difference in height between the adjacent parts, but does not hinder their opposite displacement in the horizontal direction.

The fitting parts 4, as can be seen for example from FIGS. 4 to 6, which show a first embodiment of such fitting parts, have clamps 12 which can be fastened to the ski and the middle part by means of screws 11 and a connecting rod 13 which can be pushed through the clamps 12. This connecting rod 13 prevents this a height difference between the adjacent parts, but allows lateral displacement in the horizontal direction. The clamps, the design of which can be seen in FIG. 5, can be fixed at any point on the connecting rod, as a result of which the spacing of the skis from one another and thus also from the central part can be changed.

In order to assemble the skis and the middle part and to realize the intended deformation of the skis to set a desired waist radius, a tensioning means 5 in the form of a turnbuckle is provided in the middle of the sliding board or snowboard. For this purpose, reference is made in particular to FIGS. 9 and 10. This turnbuckle has two threaded bolts 16 fastened to the ski by means of screws 14 and elbows 15 and a threaded sleeve 17 which is screwed onto the two threaded bolts 16 with opposing threads. Since the threaded bolts 16 are only fastened to the ski and the threaded sleeve 17 bridges the middle part 2, the two skis 1 can be clamped together with deformation in the transverse direction in the direction of the middle part by turning the threaded sleeve 17 in the corresponding direction, as can be seen from the comparison of 1 and 2 can be seen.

In this embodiment, the middle part 2 is adapted to the shape of the ski tips in the region of the front end and, moreover, has limits 2.1 running parallel to one another. Because of the waist radii of the skis, there is a gap which widens towards the center from the two ski ends and is designated 18 in FIG. 2. If the two skis are now tightened against each other by means of the tensioning means 5, the gap 18 becomes smaller and smaller as the skis are deformed in the transverse direction until it completely disappears when the skis are fully seated on the central part. This tensioning and deformation of the skis gives the finished assembled gliding board or snowboard waist radii that are significantly smaller than that of the skis.

In this embodiment, the middle part serves as a stop for the skis. In cases where the middle part cannot take on this task due to its instability, corresponding stops must be provided on the fitting parts, or the skis are fixed to the connecting rods by means of clamps 12. The same also applies in the event that no middle part is provided.

FIGS. 11 to 13 show the structure of a sliding board or snowboard which comprises two skis, but no middle part. Due to the lack of a central part, the two connecting rods 13 are provided with a middle section 13.1 which is reinforced in diameter and to which thinner sections 13.2 are connected on both sides. As a result, two shoulders 13.3 are formed, on which clamps 12.1 arranged on the ski rest when the skis are braced against one another by the tensioning means 5 to set a desired waist radius. Since the skis 1 are pressed against the shoulders 13.3 by the tensioning means 5, it is not necessary for the clamps 12.1 to be designed as clamps. These clamps therefore only form a plug-in connection which permits a displacement of the sections 13.2 in the clamps 12.1, but prevent a height difference between the skis.

FIGS. 14 and 15 show an embodiment in which the fitting parts are incorporated into the ski 1 and the middle part 2. As can be seen from these figures 14 and 15, the skis 1 and the middle part 2 have thickenings 19 and 20 in the region of the ends. The thickenings 19 of the skis are provided with sleeves 21 for receiving a connecting rod 13, whereby a plug connection which can be displaced in the horizontal direction is created. The connecting rod 13 is firmly inserted in the thickened portion 20 of the central part 20 and is thus held captive.

When the skis are braced in the manner described above, the skis can deform in the vertical direction, so that the tread of the snowboard thus formed is convex. In order to nevertheless obtain a flat running surface, the connecting rod 13 can, as can be seen from FIG. 16, have two bent end sections 13a which are associated with the ski, while the central part 13b of the connecting rod 13, which is assigned to the central part 2, runs in a straight line. At the beginning of the tensioning process, the skis 1 are at an angle to the central part 2, which corresponds to the bending angle of the end sections 13a with respect to the central part 13b of the connecting rod 13. If, during the tensioning process, the skis 1 move out of their normal position, the connecting rod 13 is hereby caused due to the situation that occurs Forces deformed. By appropriate choice of the bending angle of the end portions 13a, it is possible that the forces occurring deform the connecting rod 13 to such an extent that the connecting rod 13 is straight in the tensioned final state, which results in a flat running surface of the sliding board or snowboard, as shown in FIG. 17 emerges.

In the exemplary embodiments described so far, the skis 1 have been arranged in the longitudinal direction with respect to one another, which results in a symmetrical gliding board or snowboard. There can now be certain reasons for the formation of an asymmetrical sliding board or snowboard. Such a reason can result, for example, from the fact that the arrangement of binding parts on the skis leads to problems, since mounting plates are necessary for the binding parts when using the skis individually in the longitudinal direction thereof and when using the touring skis to build up the gliding board or snowboards under one Angle to the longitudinal direction must be installed. This can cause collisions between the mounting plates with each other or with the hardware components. To solve these problems, the skis are arranged somewhat offset in the longitudinal direction to one another when the gliding board or snowboard is being built, so that an asymmetrical gliding board or snowboard is produced, as is shown in FIG. 18.
