Ski sledge with central steering ski

The innovation relates to a ski sled with steering skis, in particular to a sled whose runners are made from existing ones Parts can be put together and which, thanks to its design, assumes a comprehensive utility value.

So far, for example, sledges have been used with the side Steel runners and a middle steering runner were equipped. This skid can be by pressing on the handlebar, from the control going into braking, pivot by a predetermined radius. The disadvantage is that the steering and braking can only be carried out separately. In addition, the slide has to apply pressure when braking so that the brake teeth grip the steering device can be raised. In another known embodiment, the steering device is on a normal toboggan appropriate. This steering device is engaged together with the braking device in an easily removable manner, however the steering elements including the brakes are provided with such a long boom that this creates instability between the slide and the steering, which is reinforced if the slide is loaded by several people or when he is thrown nin and fro in the lane with this load.

In the case of a decidedly ski sled, ski-like runners are used with a steering ski. The structure of this sled is but so difficult and cumbersome that assembly, for example by a layperson, at home or on the go, is unthinkable. The steering is in this version by a tubular longitudinal spar, which is rotatable in its interior Has rod that is connected at the front with the steering for the steering ski and at the rear with the edge linkage for the rear runners 1st, marked.

As experience has shown, such an intricate one is control also acting on the runners of the slide < ■ unnecessary. She makes the sledge through the complicated building no longer usable for the general public.

There is therefore a need to make a modification to the construction and assembly of such carriages. Therefore lies the innovation is based on the task of avoiding the disadvantages outlined above and a ski sled with a central steering ski to create that can be put together in the simplest possible way and, above all, is made up of parts that are affordable and are easily transportable.

The object set according to the innovation is achieved in that the ski sled with central steering ski has runners which consist of normal skis, which are connected to one another and parallel to one another via a four-point steel tube frame are and can be steered by a tiltable steering ski.

The innovation is based on the idea of using commercially available skis as runners, with or without bindings. The skis are only drilled at the front and back, so that the already resilient tubular steel frame in the front part of the ski over Resilient metal bushings and is connected to the ski ends via elastic fittings. The elastic storage increases the necessary Spring properties to absorb the vibrations during the loaded descent and to maintain the Track resistance of the sledge '.

According to the innovation, the tubular steel frame also has on an elastically mounted, padded bucket seat, which further prevents the vibration during the descent and together with the storage of the frame, it is a very comfortable vehicle suitable for rough descent. Furthermore, the steering head is adjustable and can be folded down vertically and is provided with a quick-release fastener. He can for example be folded up on the ascent with the steering ski, the better the uphill lanes

to be able to follow. The foldable steering head gives a double · « hook free, with the help of which the sledge can be attached to a ski lift. -.

The tubular steel frame has 2 independently working foot brakes, which at the same time give the feet a test stand.

The runners of the slide are on the rear part with stabilizing surfaces provided to fix the slide in the longitudinal direction, while the steering ski from a short ski-like Slider with downwardly bent guide edges. This measure gives the vehicle the necessary twist in the curves and adapts to the desired direction of travel definitely on. The steering ski, which is tilted when steering, is immensely supported by the leading edges, and the steering stabilized. The up and down movement of the steering ski is made possible by an elastic mounting, which also Dei one lateral pressure remains sufficiently flexible. A tension spring, which is attached to the steering linkage and the rear part of the steering skis attacks, the tip is always pushed down, 'so. that the carriage always remains in the desired track.

The ski sled can be used as a downhill sports device on every slope. Even on one, for normal tobogganing Impeccable steering is possible on a non-negotiable slope. Non-sports enthusiasts can use the ski sled without an accident. Even children can safely use the sled. There are no experiences whatsoever, neither in skiing still in the steering of a bobsled, necessary. The ski sledge can be transported and driven on all slopes will. The weight including the skis is a maximum of 11 kg. It can even be transported with a chair lift.

The tubular steel frame with seat and steering as well as the foot brakes can of course also be done with the necessary attachments can be mounted on existing skis. It is therefore a popular piece of sports equipment that actually bears the name and can be procured and driven by anyone.

Reference is made below to the drawings, on which an exemplary embodiment is shown in FIGS. 1 to 3 and in FIG is further explained below.

Show it:

In the ski slide 1 shown in FIGS. 1, 2 and 5 with a central steering ski 2, the runners consisting of normal or existing skis are denoted by J. The runners 3 or the normal skis are drilled at points 4, 5 * 6 and 7 and provided with a storage for the tubular steel frame 8, on which the torsion-resistant tubular steel frame 8 is in this way is constructed so that it has a good spring effect by this alone. This spring action is due to the storage still reinforced that at points 4 and 5 from three-dimensional movable vibration metal bushes and at points 6 and 7 of equally elastic fittings. This four-point bearing forces a completely parallel construction of the runners 5 of the commercially available ones Ski to each other. Another increase in the fire effect is achieved by a padded shell seat 9, which is placed on the tubular steel frame 8 with an elastic mounting is.

The central steering ski 2, which consists of a ski-like piece of runners with bevels lo, 11, is on one on the front part of the tubular frame 8 attached steering head 12 attached. This steering head can be opened vertically and is provided with a quick-release fastener. As a result, the steering head 12, incl. of the steering ski 2 folded up slightly to make the sled ready for use for mountain transport. The steering head also includes an adjustable one Handlebar IJ, which is curved and can be adjusted, that it is comfortable for every driver.

When the 'steering head 12 is folded up, an upward movement becomes possible Double hook 14 released on which the carriage 1, for example can be attached to a ski, plate or anchor lift that pulls the sledge 1 up the slope. .

In addition to the steering 2, 12, 15, the ski slide 1 has brakes 15 · These brakes 15 are designed to work independently of each other Foot brakes formed and attached to a front cross bracket 16 of the tubular steel frame 8. These easily movable brake plates With their supports, they also offer a good place to stand for your feet.

In addition to good cornering, the slide can also be used in longitudinal travel To stabilize, the runners 3 are at the rear attachment points 6 and 7 are provided with stabilizing plates 17 or stabilizing runners, which hold the carriage in the track and avoid slipping.

In order to clarify the steering ski once again, FIG. 5 the steering ski 2 shown in the folded-up version. The elastic mounting 18 and the tension spring 19 can be seen. The latter pulls the steering ski down with the tip. The folds lo, 11 directed downwards are also clearly visible. These parts help the steering ski, which is bent when cornering, to stabilize in the desired direction.
