Definitions

  • the invention relates to a sliding device, in particular alpine skis with two partial bodies made of wood, metal, plastic or the like which are arranged one above the other and connected to one another and which resiliently absorb a load acting on them due to the distance from one another.
  • the invention has for its object to provide a sliding device of the type mentioned that the human. Musculoskeletal system is largely relieved when the driving characteristics improve.
  • the object is achieved in that the partial body in the main load area, that is Alpine skis, for example, in the vicinity in front of and behind the binding, torsionally rigid with one another, resulting in a laterally open, torsionally rigid torsion box that enables the resilient absorption of the loads that occur.
  • Such a sliding device initially has a very high degree of internal damping of the vibrations, because the area of the binding is cushioned effectively and precisely in a calculable manner. Due to the torsionally stiff connection, the glider has excellent driving characteristics even on hard and icy slopes. The two partial bodies arranged one above the other result in a spring system, so that the strain on the human musculoskeletal system is considerably reduced. Overall, there are better sliding and driving properties, which has an effect in particular when cornering, which can be carried out in a more targeted manner, this being achieved in particular by the fact that the driver transmits a much more uniform pressure to the sliding surfaces. Overall, this results in a ski or a gliding device which brings considerable improvements for both the beginner and the racer.
  • the torsionally rigid connection of the partial bodies is achieved by spacers which are arranged at a distance in front of and behind the binding. These spacers are preferably designed to be displaceable, specifically in the longitudinal direction of the partial bodies. This enables simple, individual adjustment of the sliding device.
  • Another expedient design provides that the spacers are releasably connected to the partial bodies. By changing the distance through the displaceably designed spacers or the height of the spacers by corresponding replacement, the suspension properties also change in each case. This is particularly important when using the gliding device as alpine skis, because then the ski can be optimally adjusted taking into account the weight and the skill level of the skier.
  • the upper part of the body is dimensioned correspondingly or slightly longer than the length of the torsion chest. This ensures that the weight of the entire sliding device is not significantly increased. This also ensures that the entire sliding device outside the actual torsion box can be relatively soft, so that the skate-like effect is not impaired, but frontal impacts can also be absorbed and compensated for.
  • An expedient training provides that the partial bodies are connected to each other directly torsionally rigid resulting from the torsion.
  • the sliding device can also be formed in one piece with it.
  • the torsion box is divided by a kind of the lower part of the body and corresponding Bulge formed in the torsion box area to the upper part of the body.
  • there is an elegant sliding device which has a kind of gap in the main load area, as mentioned above.
  • a torsion box is formed by an upper part body and an additional part body and is connected to the lower part body in a shear-resistant manner in the assembled state.
  • the torsion box can thus. in a simple and expedient manner to the respective conditions, i.e. the driving behavior and driving skills of the respective driver can be adapted accordingly by simply replacing them as such. It can thus be manufactured as a finished part and can also be handled as such, preferably it can be built on existing sliding devices, in particular skis.
  • a sliding device is ideally suited for the various applications, in which the lower body is level and runs at the end and is curved away from the sliding surface.
  • the manufacture of such a sliding device is simple and, on the other hand, it is possible to ski with the same ski both in deep snow and on hard slopes.
  • Another advantageous embodiment is that the front part of the sliding device is gradually tapered from the torsion box towards the tip, so that the edge grip of the ski in the area of the torsion box is not impaired, but rather the edge grip is optimal in this area.
  • the upper part of the body is correspondingly wide to the load and the lower part of the body is different, which is preferably narrower.
  • the skating-like driving properties are specifically created, the spacing between the two sub-bodies ensuring that the upper sub-body cannot impair the guiding tasks of the lower sub-body or can only impair it in very special exceptional cases.
  • frontal impact is achieved by the fact that the lower part of the body is sufficiently flexible in the area beyond the torsion box.
  • Such frontal impacts can also be compensated for in that the spacers are rigidly connected to the lower part of the body and the upper part of the body is limitedly movable in the longitudinal direction and connected laterally.
  • the upper part-body carrying the binding can thus move relative to the lower part-body which has the sliding surface, so that it is not only vertical but also targeted blows can also be absorbed in a horizontal direction without the driver's musculoskeletal system being burdened with it.
  • the longitudinal mobility is achieved, for example, in that the spacers in the upper part of the body are held in longitudinal slots or have cams which are guided in the longitudinal slots, so that the torsionally rigid design is nevertheless ensured.
  • the space between the partial bodies is filled with a foam rubber plate arranged at a distance from the edge, or foam rubber strips running in the longitudinal direction at the edges are arranged.
  • the foam rubber plate or the strips have no spring effect, but are only provided to protect the space from the ingress of snow and other parts.
  • the spring effect is achieved and guaranteed exclusively by the two partial bodies arranged at a distance from one another.
  • a training provided especially for sleds and bobs provides that the partial bodies are designed as runners and are assigned in pairs to a seat frame. Due to the possible suspension of the strokes, better guidance is possible with both the sled and the bob. At the same time, the more even pressure also ensures a safer and faster glide.
  • the sliding device for surfboards In order to also use the advantages of the sliding device for surfboards, it is only necessary to additionally design the partial bodies serving as surfboards to be surrounded by a waterproof outer skin.
  • the buffering the wave shocks relieve the human musculoskeletal system considerably and at the same time the contact between board and water and thus the ability to steer is considerably improved.
  • the dynamic buoyancy can be achieved by suspension and buffering at a lower speed than with surfboards with a conventional construction.
  • the possibility of pressure distribution is particularly advantageous because, with little action, the pressure can be transferred to the various parts of the surfboard in a targeted manner.
  • the spacers can also be designed to be trapezoidal, especially in alpine skiing, and thus result in a different distance on both sides from the partial bodies.
  • This training is particularly advantageous when using the gliding device as alpine skis, as mentioned, in particular if it is a slalom or giant slalom ski. If the spacers are higher on the inside of the ski than on the outside, the pressure on the inside of the ski is transferred to the ski more than on the outside of the ski. This is also an advantage if the driver has bow legs. If, on the other hand, the spacers are higher on the outside of the ski, this suits the X-legged skiers.
  • a collapsible, ie easily transportable ski is a great advantage.
  • such a ski is achieved in that the torsion box can be pushed into one another in the longitudinal direction or the front ski can be pushed into the torsion box. This is to be pushed into each other so that there is no major negative transition, especially in the area of the tread. jump arises.
  • a sliding device has a particularly simple construction in which, according to the invention, the torsion box is designed as a full box and the lower part of the body is designed to be elastic.
  • This configuration ensures that the torsional load acting on the sliding device is introduced into the subsurface only via the torsionally rigid section and not over the length of the sliding device, so that essentially the same properties are hereby achieved. are, as with the above-explained, in the vertical direction spring acting torsion box.
  • the advantageous driving properties are essentially achieved, namely the grip as well as the turning and control behavior of the sliding device, in this short zone of the torsionally rigid section. Above all, the high specific edge pressure results in skating-like ' driving characteristics.
  • both the torsionally stiff section and the other parts of the sliding device can have a comparatively simple construction effort.
  • the rigid section can consist of a piece of wood or a plastic part.
  • the front part of the gliding device only has to be designed to absorb frontal impacts, to ensure balance and to improve general gliding.
  • a simple and optimized sliding device is achieved in that the upper part of the body is designed in whole or in part to perform the function of a binding plate. This has the great advantage that the binding plate is also integrated into the torsion box, although it is sufficient due to the specified length
  • Spare sheet Provides spring properties with the lower part of the body.
  • the invention is characterized in particular by the fact that a gliding device, in particular an alpine ski, is created which combines all extreme points of previous ski types, such as the long downhill skis and the extremely short firing glider, or which fulfills the conditions required of them.
  • a gliding device in particular an alpine ski
  • the ski constructed according to the invention rotates and holds well, similar to the alpine ski, it lies still, easily overcomes frontal obstacles such as snow, etc. and gives the driver good stability when absorbing the vertical impacts that occur and their almost complete absorption.

Abstract

Avec le dispositif de glissement (1) formé par une partie supérieure et une partie inférieure (2, 3) qui délimitent entre elles un espace intermédiaire et dont la partie soumise à la charge principale, c'est-à-dire la zone proche des extrémités de la fixation, constitue une liaison rigide à la torsion des deux parties (2, 3) grâce aux pièces intercalaires (6, 7; 4, 5), on obtient une amélioration des qualités de marche du dispositif (1). La boîte résistante à la torsion (49) constituée par ces parties, qui peut être aussi constituée par des parties (2, 3) ayant une même longueur et largeur, supporte les charges de manière élastique. De cette manière, on obtient une qualité de marche similaire à celle qu'on a avec les patins en rendant les virages aisés, et en ayant une bonne adhérence et un bon maintien dans la trace, et la conception du dispositif de glissement (1) permet d'absorber les chocs frontaux.
