Definitions

  • the invention relates to a sliding device, in particular alpine skis, with a cavity extending on both sides beyond the standing area in the longitudinal direction for absorbing impacts occurring during driving.
  • a sliding device is known in which a cavity is formed below the standing area in the ski, through which the shocks occurring during skiing are to be absorbed. It is provided that the cavity is also closed laterally, so that either a spring effect cannot be achieved or the necessary stiffness is not provided at the ends in the transition area. For these reasons, such a ski is not easy to handle, even if DE-U-8 204 143 teaches that resilient parts can be clamped between the upper part and lower part of the cavity formed in order to promote the resilient effect. Just then, however, the two parts cannot be connected to one another in a torsionally rigid manner, so that a proper skiing style cannot be achieved with the appropriately trained ski.
  • the invention has for its object to provide a generic sliding device so that the human musculoskeletal system is relieved, but at the same time an improvement in driving properties is achieved.
  • the cavity is formed by partial bodies that are torsionally rigidly connected to each other via spacers so that they result in a torsionally rigid torsion box that is open at the side, and that the lower part of the body that forms the sliding surface is soft outside the torsion box and has flexible longitudinal rigidity.
  • Such a sliding device has a very high degree of vibration damping, so that the driver's musculoskeletal system is relieved.
  • the acting torsional loads are only introduced into the subsoil over the torsionally rigid section and not over the entire length of the sliding device, so that the essential driving properties, namely the grip as well as the turning and control behavior of the sliding device, are combined in this short zone of the torsionally rigid section.
  • the high specific edge pressure results in skating-like driving characteristics. Because the torsional loads are no longer transmitted over the length of the sliding device, both the torsionally stiff section and the other parts of the sliding device can have a comparatively simple construction effort.
  • ski properties benefit from the fact that the lower part of the body has a soft and flexible longitudinal stiffness outside the torsion box, so that frontal impacts are absorbed and the balance is optimally maintained by improving general sliding. All in all, this results in a ski or a gliding device that brings significant improvements for both the beginner and the racer.
  • the simpler design is also achieved in particular by the fact that a prestressing of the lower part of the body forming the sliding surface is not necessary. Rather, it forms the torsionally rigid torsion box in the connection area with the upper part of the body. Since the torsionally rigid torsion box is designed to be open on the side, the desired spring action or damping action can become fully effective.
  • the spacers precisely delimit the desired torsion box and ensure that such a torsion box, which has a positive influence on the driving properties, is effectively specified precisely in the desired area.
  • An expedient embodiment of the invention provides that the spacers are detachably connected to the partial bodies. Are least selectively altered or adapted to the respective conditions of use: the region of influence of Torsionska can by changing the distance by the slidable formed spacers or the height of the spacers. An adjustment is also possible in this way with regard to the weight and driving ability of the respective driver.
  • the length of the torsion box accordingly or slightly longer. This ensures that the weight of the entire sliding device is not significantly increased. This also ensures that the entire sliding device can be kept relatively soft outside the actual torsion box, so that the skate-like effect is not impaired, but on the other hand also frontal shocks can be absorbed and the driving properties can be advantageously ensured.
  • An expedient further embodiment provides that the partial bodies are made in one piece and the torsion box is formed so as to form a gap between the two partial bodies and the spacers.
  • the sliding device can thus also be formed in one piece, which can have a positive influence on the overall appearance of the sliding device.
  • the torsion box is formed by a kind of division of the lower part body and corresponding bulging in the torsion box area to the upper part body. The clear spacing of the torsion box is achieved. In this case, this results not only in an elegant sliding device, but also in a construction which advantageously derives the main forces.
  • the torsion box is formed by an upper part body and an additional part body and is connected in a shear-resistant manner to the lower part body in the assembled state.
  • the torsion box can thus in a simple and convenient manner the respective conditions, ie. H. be adapted to the driving behavior and driving skills of the respective driver 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 placed or clamped onto existing sliding devices, in particular on skis.
  • Such a ski can be safely driven, especially in deep snow, but also on hard slopes.
  • Another advantageous embodiment is that the lower part of the body of the sliding device tapers from the torsion box towards its front end pointing towards the ski tip, so that the edge grip of the ski in the region of the torsion box also does not impair, but rather the edge grip exactly in this Area is specifically targeted.
  • the skiing properties of the ski are thus advantageously improved, the front and possibly also the rear end of the ski beyond the torsion box advantageously having the desired points and flexible longitudinal stiffness properties.
  • the partial bodies of the same length and width and, in addition to the spacers resulting from the torsion box, to connect them by means of further spacers arranged outside the torsion box.
  • the effect of the torsion box is given because it is precisely defined by the spacers delimiting it, while the remaining spacers, preferably at the ends of the two partial bodies, essentially only have the task of effectively holding the two partial bodies together in this area as well.
  • the upper part of the body is correspondingly wide to the load and the lower part of the body is different, preferably narrower.
  • This design optimizes the skating-like driving properties, whereby the distance between the two partial bodies ensures that the upper partial body cannot impair the guiding properties of the lower partial body or can only impair it in very special exceptional cases.
  • the space between the partial bodies is filled with a foam rubber plate arranged at a distance from the outer edge of the partial bodies or that the longitudinal edge extends at the outer edge Foam rubber strips 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 or other parts.
  • the spring action is achieved and ensured exclusively by the two sub-bodies arranged at a distance from one another.
  • a training intended especially for sledges and bobs provides that the partial bodies are designed as runners and are assigned in pairs to a seat frame. Due to the possible cushioning of the slope, better guidance is possible with both the sled and the bob. At the same time, the even pressure also ensures safe and faster gliding.
  • the partial bodies which are connected to form a torsion box together with the spacers, together form the runners of the slide.
  • the partial bodies connected to one another in a torsionally rigid manner serve as surfboards, the torsion box thus formed being additionally surrounded by a waterproof outer skin.
  • the waves can be buffered by the surfboard when driving over them, so that the human musculoskeletal system is considerably relieved.
  • the contact between the board and the water and thus the tax ability improved.
  • the dynamic appearance can be achieved by suspension and buffering even at low 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 in a trapezoidal shape, in particular in alpine skis, and thus result in a different distance between the side edges of the partial bodies.
  • This training is particularly advantageous when using the gliding device as an alpine ski, 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 transmitted more than on the outside of the ski. This is also an advantage if the driver has 0-legs. If, on the other hand, the spacers are higher on the outside of the ski, the X-legs will do so . Towards drivers.
  • Such a ski is achieved according to the invention if 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 done by pushing each other in such a way that there is no major negative transition point, especially in the area of the tread.
  • a ski that is simple in construction or a corresponding sliding device can achieve improved properties if the lower part of the body is designed to be elastic beyond the torsion box, the torsion box being formed by a board or a full box covering the standing area.
  • the torsional load acting on the sliding device is thus only introduced into the ground via the torsionally stiff section and not over the entire length of the sliding device, so that advantageous driving properties result.
  • the suspension in the vertical direction is omitted, so that the driver's musculoskeletal system cannot be relieved.
  • the simple structural outlay is thus paid for with disadvantages, but these are not given if the upper part of the body is also designed, in whole or in part, to function as a binding plate.
  • the torsion box which is torsionally rigid and relieves the musculoskeletal system, the binding plate being structurally advantageous to be placed in the torsion box.
  • the invention is characterized in particular by the fact that a sliding device, above all an alpine ski, is created which combines all extreme points of previous ski types, such as the long downhill ski and the extremely short firing glider, or which fulfills the conditions required of these. Similar to the firing glider, 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.
  • the sliding device according to the present invention can advantageously be used both as alpine skis, as cross-country skis, and as sledges, ski bobsleds, water skis or surfboards.
  • the defined design and shape of the torsionally rigid torsion box provides skate-like and therefore precise and easy-to-use driving properties for such a ski.
  • an alpine ski is shown as a sliding device (1), which has an upper part body (2) and a lower part body (3).
  • the upper part body (2) and the lower part body (3) are connected to each other in a torsionally rigid manner.
  • the torsionally rigid connection takes place in the embodiment shown in FIG. 1 via the spacers (6, 7), the partial bodies (2, 3) either being directly connected by the spacers (6, 7) as in FIG. 1 or else 5 additionally by a transition of the upper part body (2) into the lower part body (3).
  • Another possibility of forming the torsion box, which is marked with (49), is shown in FIG. 6.
  • additional partial body (48) is provided, which together with the upper partial body (2) and the spacers (6, 7) results in the actual torsion box (49).
  • This torsion box is placed on the lower part of the body (3) and connected to it. This ensures a uniform load in the area of the sliding surface (47) of such a ski.
  • FIG. 2 A further embodiment is shown in FIG. 2, in which the two partial bodies (2, 3) are of the same length and width and are arranged one above the other. You will be adding to the distance pieces (6, 7) connected by the end spacers (4, 5). However, the torsion box (49) is formed between the two spacers (6, 7) as in the other designs. With (8 and 9) the edges of the two partial bodies (2, 3) are designated, which apart from the edge (9) require no special treatment. Even the edge (9) can usually do without steel protection, because the grip over the torsion box (49) is guaranteed in the correspondingly short loaded area. 2, the binding plate (22) is at the same time part of the upper partial body (2). It is also conceivable that, in a configuration corresponding to FIG. 1, the entire upper part of the body (2) also takes over the function of the binding plate (22).
  • Fig. 4 shows a design in which the spacer (6) and of course also the spacer (7), not shown here, are trapezoidal in such a way that an oblique position of the upper part body (2) to the lower part body (3) is created, which is particularly advantageous for slalom, downhill, etc.
  • a rigid board (50) or a full box is placed on the partial body (3) forming the sliding surface (47) instead of the actual laterally open torsion box.
  • the lower part of the body is elastic in the area outside of this rigid board (50) or the full box.
  • Fig. 7 shows a principle similar to Fig. 2, in which it is clarified that the space (37) between the two partial bodies (2, 3) is closed by a foam rubber plate (14) to prevent the ingress of snow o. to prevent.
  • This foam rubber does not take on spring properties here, but rather only the task of closing off this area.
  • the formation of longitudinal slots (19, 20) in the upper part of the body (2) is possible in order, for example, to allow the snow which has once penetrated to emerge if, for some reason, the use of foam rubber or the like is not possible.
