BRIEF SUMMARY
TECHNICAL AREA
The present invention concerns a sporting device with an oblong, plate-shaped foundation according to the preamble of claim 1.
STATE OF THE ART
The genre-forming state of the art emerges from DE 27 11 930 A1. A device for sliding on snow is depicted in FIG. 7 of this publication, on the underside of which in the middle area a system of guides is provided which includes two outer guides 10, two inner guides 9 between the outer guides 10, and a central guide 8 which can also be shorter or longer than is depicted in FIG. 7. The guides 9 are arranged symmetrically to guide 8 and slightly arched, whereby the arching is greater in the rear area. The outer guide 10 is even more strongly arched than guide 9 (see description, page 24, third and fourth paragraph). From this it follows that the distance between the guides 9 and 10 increases toward the rear. Nothing is said on the height of the guides of the embodiment of FIG. 7 of DE 27 11 930 A1.
Since the guides of the embodiment depicted in FIG. 7 are basically of equal length, the guides form lines of force which essentially run parallel to the longitudinal axis. A change in direction can only be executed by a complete weight shift of at least 50% on one of the parallel force lines. This way, a change in the foot position is required which necessarily leads to a labile center for the operator. If the guides 8, 9, 10 are arranged at equal height, the steering action of the individual guides is mutually cancelled. This can only be avoided by great differences in height as depicted in FIGS. 9 through 12 of DE 27 11 930 A1. Such a measure nonetheless leads to increased angles of inclination and therewith to an instability of the operator in changing direction.
REPRESENTATION OF THE INVENTION
Underlying the invention is the object of creating an easily steerable sporting device with simple means of construction.
This object is realized by a sporting device according to patent claim 1.
The greatest advantage of the sporting device of the invention lies in its maneuverability.
The sporting device of the invention offers, among other things, the possibility of going down slopes standing, sitting, or lying down. Further areas of use of the sporting device of the invention consist, for example, in that the invention can also be used as a sleigh or as a children's sled. The sporting device of the invention also offers its user the possibility of being pulled by a T-bar lift installed on an even surface like when water skiing. The sporting device of the invention in addition offers the user the possibility of bodily activation under the impression of his sense of balance. With the sporting device of the invention, the user can enjoy sliding downhill on snow-covered slopes with the complete maneuverability of a skateboard analogous to surfing without having to transport a heavy sled or a large snow board up the slope.
Advantageous configurations of the sporting device of the invention are the object of patent claims 2 to 7.
SHORT DESCRIPTION OF THE DRAWINGS
An embodiment of the invention is described in greater detail through drawings. Depicted are:
FIG. 1 A view of the sporting device from below.
FIG. 2 A side view of the sporting device of FIG. 1.
FIG. 3 A cross section A--A through the foundation of the sporting device of FIG. 2.
BEST WAY TO CONSTRUCT THE INVENTION
The sporting device has a basically oval, plate-shaped foundation 10 which has an upper side 11 and an underside 12.
The foundation 10 rises in the front third in an angle of approximately 10.degree. and forms a uniformly slightly arched slope to the tapering front part. The rear two-thirds of the runner support issue level in front of the rear incline in the slope toward the horizontal of the foundation 10, and form a flowing transition to the rear incline. The front area 13, which can occupy 1/6 to 1/10 of the overall length of the foundation 10, and the rear area 14, which can occupy approximately 1/5 to 1/7 of the overall length of the foundation 10, are in each case inclined upwa
