DESCRIPTION:
BRIEF SUMMARY
The invention concerns a sliding vehicle, particularly for sliding on snow and ice, with a bottom surface having sliding surface and a seat for at least one person.
Sliding vehicles that can be used on snow and ice are known in various forms. In addition to the sliding vehicles which have been known for a long time and which are designed as sleds with a fixed sled frame, many forms of sliding vehicles are known which are made particularly of plastic. In a simple known embodiment, the sliding vehicle is substantially a thin, double-layered mat with a thin layer of upholstery material in between. At the front is arranged a handle with which the driver lifts the front part of the mat to permit sliding. This known embodiment fulfills the driver's wish for a light-weight, non-voluminous sliding vehicle, but it has the disadvantage that bulge of the mat formed by lifting the front handle has a braking effect, particlarly on soft snow since snow piles up there.
The object of the invention is therefore to design a sliding vehicle of the above-mentioned type which, while maintaining the advantage of a light-weight and space-saving design, has good sliding properties in all snow conditions and which is easy to steer.
This problem is solved according to the invention by structuring the sled such that the bottom surface is a rigid shield with at least two shield sections, which are joined with each other by a film hinge joint extending in the longitudinal axis of the sliding vehicle. The film hinge joint extending in the longitudinal axis of the sliding vehicle. permits in a simple manner changes of direction during sliding. At the same time the film hinge joint permits folding of the shield so that the sliding vehicle, despite its rigid shield, can be reduced to small dimensions for easy transportation.
According to the invention, the sliding vehicle can further be used as a coat hanger.
The invention is represented in the drawing various embodiments and will be described below.
FIG. 1 shows a top view of a sliding vehicle according to the invention.
FIG. 2 shows a section of the sliding vehicle according to FIG. 1 along line II--II in FIG. 1.
FIG. 3 shows on an enlarged scale a partial section of the sliding vehicle according to FIG. 1 along line III--III in FIG. 1.
FIG. 4 shows a top view of another embodiment of the sliding vehicle according to the invention.
FIG. 5 shows on an enlarged scale a partial section of the sliding vehicle according to FIG. 4 along line V--V in FIG. 4 and
FIG. 6 shows a variant of a detail of the sliding vehicle according to FIG. 4.
The sliding vehicle shown in FIG. 1 has a bottom surface 1 in the form of a shield. Bottom surface 1 has two shield sections 2,3 which are joined with each other by a film hinge joint 4, as can be seen from FIG. 2. It is important that the film hinge joint extends in a direction parallel to longtudinal axis 5 of bottom surface 1. The embodiment according to FIGS. 1-3 shows a single film hinge joint 4, but bottom surface 1 could also be provided with several parallel piano hinges 4. Corresponding to the greater number of film hinge joints 4, the number of shield sections 2, 3 would also have to be increased correspondingly.
As can be seen from FIG. 2, bottom surface 1 has a sliding surface 6 and a seat 7. Sliding surface 6 is preferably designed as a rigid thin-walled hollow shell, preferably of plastic, e.g. polyethylene. Hollow shell 6 forming a flat shell has a curved outer edge 8 and in each shield sections 2,3 a skid 9, but more than one skid 9 can be arranged in each shield section 2,3. Film hinge joint 4 is preferably located in the area of seat 7, so that it closes a groove 10 formed between shield sections 2,3. Groove 10 has a form widening toward sliding surface 6, as can be seen from FIG. 2. If the transition of the two lateral surfaces of groove 10 into sliding surface 6 proper is sharply edged, this has an additional guiding effect. Seat 7 is preferably made of a soft material, particularly of a plastic foam, such as polyethylene foam, where the m
