Description

Multifunctional ski

FIELD OF THE INVENTION The present invention relates to a ski, in particular an alpine ski, which can be used in a multifunctional manner and can be flexibly and optimally adapted to different environmental conditions and / or users.

BACKGROUND OF THE INVENTION So-called carving skis are known in the prior art, which are designed to be tailored so that they have a central section which is narrower than the two ends of the ski. The widths of the skis at both ends can vary widely and are generally between 90 and 120 mm, while the central region has a width of around 60 to 90 mm. The width of the ski at the two ends is usually different, the width at the front in the blade area of the ski generally being greater than at the end of the ski. However, carving skis are also known in which the width at the end of the ski is greater than in the area of the shovel.

The optimal ski shape depends, among other things, on the external environmental conditions, the intended use and the slope conditions, so that none of the known carving skis offer a versatile range of uses that can be optimally adapted to the respective ambient conditions and slope conditions.

DE-C-44 03 499 relates to a cross-country ski with a scale-like tread pattern provided on its underside and a cross-country binding attached to its top. So that the cross-country ski can be moved in both directions, it has an upward bend at both ends. Furthermore, the binding is designed such that the ski boot can be fastened therein in both directions of travel. For this purpose, the binding can either have two opposing binding jaws for receiving the ski boot or a binding jaw arranged rotatably about an axis perpendicular to the upper side of the ski. Summary of the invention

It is an object of the present invention to provide an improved ski which can be variably adapted in particular to a wide variety of environmental conditions and / or users. This object is achieved with the features of the claims.

The invention is based on the basic idea of bending up both end sections on a ski that is asymmetrical with respect to its transverse axis or on a ski with a positive or negative taper, in order to provide ski tips with a shovel on both sides, and to attach a binding plate to the ski that has at least can be fixed in two different positions. In the first position of the binding plate, a first end section of the ski forms the ski tip, and in the second position the opposite second end section of the ski forms the ski tip. The binding plate is preferably attached to the ski in such a way that an optimal binding mounting point can be set for both positions. For this purpose, it is particularly preferred that an axis of rotation of the binding plate is arranged such that the binding mounting points are optimally positioned both in the first position and in the second position. For this purpose, the axis of rotation is preferably located in an area between the two jaws of the ski binding to be mounted on the binding plate.

This provides a ski that can be optimally adapted for different purposes depending on the snow or slope conditions or also on the requirements of the respective skier. In particular, the ski according to the invention is in a particularly advantageous manner on both conventional, for. B. hard and icy slope conditions, as well as adapted to deep snow and mogul slopes and jumps. For example, a carving ski in which the front shovel is wider than the rear end of the ski is very well suited for "freeride" techniques (carving on and off the slopes), while a ski that is narrower in the front shovel area is suitable for "freestyle" or " Slopesyle ", especially for jumps, creates better conditions. Consequently, the ski according to the invention, which can be used bidirectionally and in which, depending on the rotational position of the binding plate, either the front or the rear shovel is wider and also the binding mounting point is variable, is an ideal choice various Customizable ski requirements and environmental conditions provided. The ski therefore offers maximum buoyancy and smoothness in the freeride position due to the wide shovel and the narrower rear end, e.g. in untracked snow, and in the slopestyle position due to the narrower shovel and the wider rear end as well as the shifting of the binding mounting point Weight distribution for tricks and more stability when landing jumps.

Detailed description of the invention

The ski 2 according to the invention shown in FIGS. 1 and 2 essentially has a ski body 4 with a first end section 6 and a second end section 8 and a binding plate 10. The ski body 4 is bent up in the region of the end sections 6 and 8 in order to form respective ski-shaped ski tips 12 and 14. On The binding plate 10 has a binding with a front binding element 16 for receiving a tip of a ski shoe 17 and a rear binding element 18 for receiving a rear portion of the ski shoe 17 mounted.

The ski body 4 of the ski 2 according to the invention is designed asymmetrically with respect to its transverse axis, i. H. the width of the ski body 4 at the two end sections 6 and 8 is different, which is achieved, for example, by a suitable waist of the ski body, in that the center of the radius forming the waist is shifted in the longitudinal direction with respect to the center of the ski length. In the preferred embodiment, the ski according to the invention has an overall length L of approximately 180 cm. The maximum width of the ski body 4 at the first end section 6 is preferably approximately 111 mm, this width being measured at a distance of approximately 110 mm from the first ski tip 12. The maximum width of the ski body 4 at the second opposite end section 8 is approximately 106 mm, this width being measured at a distance of approximately 1,700 mm from the first ski tip 12. The minimum width of the ski body 4 is preferably approximately 75 mm at a distance of approximately 934 mm from the first ski tip 12. The radius of the waist of the ski body 4 is preferably approximately 18.57 m. Accordingly, the ski body 4 has a waist, through which the respective widest points in the end sections 6 and 8 are of different widths, i. H. the waist has a taper dimension, so that depending on the rotational position of the binding plate 10, either the ski is wider at the front (positive taper) than the rear or vice versa (negative taper).

The ski 2 according to the invention can be variably adjusted to a wide variety of environmental conditions and users in that the binding plate 10 can be fixed on the ski body 4 in two opposite directions. That is, in a first position the front part of the binding plate for receiving the front binding element 16 according to FIG. 1 faces the first ski tip 12, while according to FIG. 2 this front section of the binding plate 10, which carries the front binding element 16, points towards second ski tip 14 has. Any mounting mechanism which is suitable for fixing the binding plate 10 with sufficient strength in the two positions on the ski body 4 can be used for mounting the binding plate 10 on the ski body 4. However, it is preferred to use this mounting device in Form a quick or snap fastener that allows a change of the binding plate from the first position to the second position without the use of tools. It should also be noted that there may be snow or ice in the area of the binding plate 10 and binding of the ski 2 according to the invention, which complicates handling of the mounting device, so that the mounting mechanism should be designed so that it remains functional even under these conditions.

In addition to the two mutually opposite first and second mounting positions of the binding plate on the ski body 4, the binding plate 10 can also be designed to be longitudinally displaceable on the ski body 4. This can be particularly helpful for setting the optimal binding mounting points for the respective direction of use of the ski 2 according to the invention. Preferred shoe center markings SMM1 and SMM2 for the optimal mounting points of the respective direction of travel are shown in FIGS. 1 to 3. To set both mounting points, the pivot point should be suitably chosen and / or the binding plate 10 should be movable in the longitudinal direction. The binding itself is preferably also adjustable in the longitudinal direction on the binding plate 10.

One way of moving the binding plate 10 relative to the ski body 4 from the first position shown in FIG. 1 to the second position shown in FIG. 2 is to rotate the binding plate 10 about a pivot point 20, as is exemplified in FIGS 4 is shown. According to this embodiment, the binding plate 10 on the ski body 4 is held on the ski body 4 by means of a rotary guide device 22 so as to be rotatable about the pivot point 20 and preferably axially displaceable. For this purpose, the binding plate 10 has an undercut guide slot 23, in the undercut of which a rotating piece (not shown) mounted on the ski body 4 engages. The binding plate 10 is freely rotatable about this rotating piece. Furthermore, at least one, preferably two undercut slots 24 running in the circumferential direction are provided on the binding plate 10. To fix the binding plate 10 to the ski body 4, two mounting elements 26 are provided on the ski body, preferably per slot 24, one of which is shown in more detail in FIG. The mounting element 26 has a sleeve section 28 and a plate section 30 and is by means of a through-hole tion 32 attachable to the ski body 4. The binding plate 10 is pivoted about the pivot point 20 for fixing to the ski body 4, so that the slots 24 are pushed over the mounting elements 26. The plate sections 30 of the mounting elements 26 engage behind the undercuts of the slots 24, as a result of which the binding plate 10 is fixed on the ski body 4. To fix this position, the binding plate 10 has at least one, preferably two bores 34 in the area of the slots 24. To secure the position of the binding plate 10 on the ski body 4, two locking pins (not shown) are preferably inserted into the bores 34 so that they are positioned between an adjacent pair (transversely adjacent) of mounting elements 26 to pivot the binding plate 10 relative to the Prevent ski body 4. Locking pins can in turn be fixed to the binding plate by a suitable locking means.

When changing the position of the binding plate 10 from the orientation shown in FIG. 1 to the configuration shown in FIG. 2, the securing pin must first be removed and then the binding plate 10 must be pivoted about the pivot point 20 until it is the same after being rotated by approximately 180 ° Way is fixed as described above. For this purpose, mounting elements 26 are provided on the ski body 4 on both sides of the pivot point 20, as shown in FIGS. 1 and 2. Contrary to the embodiment shown, it is preferred, however, to provide the mounting elements 26 on both sides of the pivot point 20 such that they are covered by the binding plate 10 in both positions.

The optimal mounting point of the binding plate 10 in the respective positions can be set by the rotary guide device 22. This device allows the binding plate 10 to be displaced in the longitudinal direction relative to the ski body 4, which provides additional variability. In this regard, it is also possible to provide further slots 24 on the binding plate 10, so that the binding plate can be fixed in further axial positions.

A further possibility, which is similar in principle, of bringing the binding plate 10 relative to the ski body 4 from the first position shown in FIG. 1 to the second position shown in FIG. 2 is shown in FIG. 6. In this embodiment, too Binding plate 10 is rotatably attached to the ski body 4 about an axis of rotation. To change the direction of the binding on the ski, a locking flap 36 is first opened according to FIG. 6A until it engages. As a result, the locking of the binding plate 10 on the mounting elements 26 is released. The locking flap 36 is part of a locking or mounting device 38 with which the binding plate 10 is fixed to the ski body 4. The locking device 38 preferably has a toggle lever mechanism and is spring-loaded. After the locking flap has been opened, the binding plate 10 can be raised about a pivot axis 40 provided on the mounting device 38, as can be clearly seen in the middle illustration of FIG. 6B. As a result, the binding plate 10 is lifted off the mounting element or slot nut 26 and slot plate 27 provided on the ski body 4 in the direction of the arrow 42 (middle illustration in FIG. 6B). The grooved plate 27 is preferably used, among other things, to guide and / or fix the binding plate 10. The binding plate 10 can be rotated in this state according to the lower illustration in FIG. 6B about an axis of rotation in the direction of the arrow 44. The rotary connection between the ski body and the binding plate 10 takes place via the mounting device 38, which is connected to the ski body 4 by means of an axis of rotation. The axis of rotation is positioned on the mounting device 38 and on the ski body 4 in such a way that the binding plate 10 and thus the binding takes on an optimal binding mounting position in both positions, ie the center of the boot is in the most favorable position provided. In a preferred embodiment, the binding mounting point shifts by about 2 to 6 cm, preferably about 3 cm, in the "slopestyle" position, ie with a narrower blade and wider end, compared to the "freeride" position, ie with a wider blade and narrower end to 5 cm, particularly preferably about 4.1 cm to the center.

To limit the pivoting movement of the binding plate 10 about the axis of rotation 40, it is further preferred to provide a retaining band 46, the ends of which are attached to the binding plate 10 or the mounting device 38. After rotation by 180 °, the binding plate 10 is brought back onto the ski body 4 in the direction of the arrow 48 as shown in FIG. 6C on the left. The locking flap 36 is then closed, as shown in the right illustration of FIG. 6C, as a result of which the binding plate 10 is fixed again. The on the binding plate 10 mounted binding 16, 18 is now in a ready-to-drive position, which is rotated by 180 ° compared to the original position. The embodiment according to FIG. 6 is advantageous over the first embodiment in particular due to its simplified handling and increased stability. In this embodiment of the mounting device, all mounting elements are also arranged independently of the position of the binding plate 10 on the ski body 4 below the binding plate 10 and are therefore not visible and better protected against contamination or icing.

As an alternative to the embodiment described above, it is also possible to provide a sliding mechanism instead of the rotating mechanism, which enables the binding plate 10 to be pushed onto the ski body 4. In such an embodiment, the binding plate 10 on the ski body 4 can be displaced in the longitudinal direction and / or removed from it and fixed again in the opposite direction with the aid of a quick-release fastener. According to this embodiment, an additional variability would be given by the fact that the binding plate 10 can be designed to snap in at a number of different longitudinal positions.

The ski according to the invention allows an optimal adaptation to a wide variety of environmental conditions and skiing habits of a skier, so that the ski according to the invention can be used in a much more variable manner than conventional skis. The construction according to the invention is particularly advantageous because, with it, the relatively high forces and moments that occur in particular in alpine skiing are safely transmitted from the binding consisting of the front and rear cheeks to the ski via the binding plate, simultaneously in both directions of travel of the ski the binding is positioned at the most favorable position.
