Definitions
- the invention relates to devices for specifically influencing the longitudinal curvature of a ski according to the preamble of claim 1.
- Skis for both alpine skiing and cross-country skiing are made so that they are convex in the central area where the ski binding is mounted.
- This longitudinal curvature disappears under the influence of the weight of the skier; at the same time, the ski tip and ski end are pressed into the snow with the appropriate forces. This ensures that the ski has good contact with the snow, keeps the track well, does not flutter when skiing, etc.
- this convex longitudinal curvature also has leverage. It prevents the ski from turning. The skier must improve the turning of the skis - if necessary by means of active high or low relief.
- Trickski runners prefer to use short skis with low longitudinal curvature. However, these skis have poor straightness.
- a further disadvantage of the convex longitudinal curvature is that it hinders cornering, in particular with edge grip, since the natural longitudinal curvature of the ski is exactly the opposite of the curvature required when cornering.
- Racers therefore prefer to use heavily waisted skis that are considerably wider in the area of the tip and end than in the area of the binding. The stronger this waist, the tighter the corners can be negotiated.
- various accidents, some unfortunately with fatal results, show that the handling characteristics of these highly tailored skis are very problematic.
- the present invention has for its object to provide a device as simple as possible, with the help of the skier can consciously change the longitudinal curvature of his ski while driving from the original convex shape to a more or less concave shape.
- the skier can selectively bend the part of the ski with which the load arm of the lever is connected by a metered shift of his weight to the power arm, even a concave longitudinal curvature being achievable.
- the lever according to the invention is with every ski can be retrofitted. It can be individually adjusted to the respective shoe size.
- the weight of the skier and the elasticity of the ski can be coordinated by changing the length of the power arm.
- a ski equipped with two levers according to the invention can be turned considerably more sensitively without losing the edge grip and dynamics necessary in the swing control phase.
- the skier can achieve this by shifting his weight towards the tip of the ski when turning, so that the tip of his ski shoe exerts pressure on the power arm of the front lever, whereupon the load arm pulls the tip of the ski upwards.
- a ski equipped with two levers according to the invention already has a slight concave deflection when it is folded up, which supports easy turning, but at the same time ensures that the ski has a very good edge grip below the binding, where it makes most sense and is most important has what it is absolutely necessary for driving on ice. Shifting weight forward or backward is transferred to the ski by the leverage, so that it can be mastered easily and with little effort in any situation.
- Ski racers can also benefit greatly from the present invention. If the racer drives through a curve with skis up and at high speed, centrifugal forces are generated which significantly increase his effective weight. As a result, additional forces are exerted on both levers, whereupon the ski tip and ski end are pulled upward accordingly and the ski receives the concave longitudinal curvature which is optimal for negotiating tight curves. This effect is also effective with less skis that are more tailored.
- the present invention is not to be confused with the common assembly of the ski binding on an intermediate plate, which in turn is mounted at a distance from the ski, as described for example in DE-A 41 00 327 or DE-A 43 18 513.
- These known devices primarily have the task of preventing the ski boot from touching the snow when the skis are edged.
- the intermediate ragp l at te which must be rigid because of the safe release of the ski binding in the event of falls, etc., intend to decouple from the ski so that it can retain its natural elasticity.
- the intention Device according to DE-A-41 00 327 further to be able to position the points at which the forces between skiers or ski bindings and skis are transmitted, regardless of the shoe size.
- ski binding is therefore attached directly to the power arm of the lever.
- the ski binding is attached, for example, to pre-drilled holes with screws.
- it is also an integration of the lever in the ski binding or in the ski.
- This spring is preferably made of an elastic
- Materi a Lblock of suitable hardness, in particular made of plastic or rubber, realized that the space between Filled with little power and skis so that ice and snow cannot penetrate here.
- Another development of the invention provides a height stop which limits movement of the power arm away from the ski. This stop serves to improve the driving experience by preventing the tip of the ski boot from pulling the power arm of the front lever upward, for example, in the event of an extreme shift of weight, whereupon the ski's seats are pressed down strongly into the snow or that Triggering behavior of the ski binding would be delayed.
- FIG. 3 is a side view of a conventional ski equipped with two levers according to the invention
- Embodiment of a ski equipped with the levers according to the invention and a conventional ski binding Embodiment of a ski equipped with the levers according to the invention and a conventional ski binding
- Fig. 6 shows an embodiment of a ski levers according to the invention and integrated ski binding
- Fig. 8 shows an embodiment with a cross-country ski.
- Fig. 1 shows a usual, unloaded ski 1 with tip 2 and end 3.
- the central area 4, where the ski binding is mounted, has a convex longitudinal curvature.
- Fig. 2 shows the ski of Fig. 1, loaded with the Ge icht G of a skier. The middle area 4 is now stretched. Ski tip and ski end press on the surface with force K1 or K2.
- FIG. 3 shows the ski of FIG. 2, but with two additionally mounted, stiff Z-shaped levers 10 with power arm 11 and load arm 12.
- the power arms 11 are positioned such that they are from the heel or tip of a ski boot (not shown) can be burdened.
- the load arms 12 are firmly connected to the ski 1.
- the power arm 11 of the lever 10 assigned to the ski end 3 is loaded with the larger partial weight Gh
- the power arm 11 of the lever 10 assigned to the ski tip 2 is loaded with the smaller partial weight Gv.
- This weight distribution results, for example, from the fact that a skier (not shown) shifts his body weight backwards.
- the Te l weight Gh presses the power arm 11 of the lever 10 down.
- Characterized the load arm 12 of the rigid lever 10 and with it the ski end 3 is pivoted upwards.
- the ski 1 has an essentially concave longitudinal curvature. It can be turned easily. You can make tight turns with a concave and upturned ski.
- both levers 10 are additionally loaded, whereupon the ski 1 receives a reinforced concave longitudinal curvature that optimally supports cornering. As soon as the skier flattens the ski 1 again, these additional forces disappear and the ski 1 regains its usual properties.
- FIG 4 shows a first embodiment of the lever 10 according to the invention on a downhill ski 1 shown in sections.
- the load arms 12 of the two Z-shaped, rigid levers 10 are screwed to the ski 1 with the aid of four screws 15 each.
- a conventional ski binding 30.1, 30.2 is positioned above the two levers 10 and screwed to the ski 1 with the aid of screws 35. The screws 35 are inserted without contact through enlarged openings 16 in the levers 10.
- a ski boot 7 with heel 8 and toe 9 is between the holding plates 32, 34 and the holding jaws 31, 33 of the Ski binding 30.1, '30 .2 fixed.
- the force arms 11 of the two levers 10 are positioned so that a skier can exert pressure on them by means of heel 8 or toe 9 of the ski boot 7, which leads to a change in the corresponding ski part.
- Fig. 4 also shows two examples of devices with whose help the deflection of the force arms 11 of the levers 10 and thus the dimension of the maximum possible concave longitudinal curvature of the ski 1 can be limited.
- a stop block 13 is mounted under the force arm 11 of the lever 10 shown on the left in the drawing, which limits the movement of the force arm 11 to the height of the gap S.
- the stop lotz 13 can also be mounted on the ski 1.
- the power arm 11 of the lever 10 shown in the drawing on the right is equipped on its underside with a Ke l 14, which includes an angle alpha to the top edge of the ski.
- the power arm 11 can only be moved until the Kei l 14 lies flat on the ski 1.
- FIG. 4 also shows that the load arms 12 of the levers 10 have at their free end a recess facing the ski 1, which is filled with an elastic material 17.
- the elastic layer 17 enables the ski to spring when skiing, even when using long levers 10, due to correspondingly long ski bindings 30.1, 30.2, and prevents the ingress of ice and snow.
- FIG. 5 shows an alternative fastening option for a lever 10 '.
- a C-rail 40 is mounted, in which the load arm 12 of the lever 10 'in the longitudinal direction of the ski can be adjusted and fixed with the aid of a stopper 41.
- FIG. 6 again shows a downhill ski shown in sections, in which the ski binding 30.1, 30.2 is integrated on the lever 10.
- the load arms 12 are fastened to the ski with screws 15, but here with a thin intermediate layer 19, with whose help any unevenness can be compensated for.
- the gap between the power arms 11 and the ski 1 is filled with an insert 18, in particular made of plastic or rubber. This prevents ice and snow from entering.
- the elastic insert 18 also acts as a spring and thus compensates for the basic weight of a skier, at least in part.
- the Shore hardness of the insert 18 is selected according to the weight of the skier. This ensures that when the skier shares his weight evenly on the front and rear levers 10, the power arms 11 remain in their basic position and the ski 1 retains its normal properties.
- a height stop 20 here in the form of a correspondingly screwed-in screw, is provided.
- FIG. 7 shows a modified embodiment of a ski 1 '.
- the load arm of the lever 10 ' is integrated in the ski 1'.
- the power arm 11 carries prepared bores 21, optionally with a thread, for easy attachment of a ski binding.
- levers according to the invention can also be used with a cross-country ski 1 '.
- the lever 10 facing the ski tip carries a ski binding 30.3 which holds the tip 9 of the long-running shoe 7 '.
- the heel 8 of the cross-country shoe 7 ' is free, as is customary in cross-country skiing. Nevertheless, it is also possible to control the longitudinal curvature of the cross-country ski 1 'in the desired sense by shifting the body weight to the heel 8 or toe 9.
- the invention applies to all types of skis.
