Abstract

The invention relates to a drive module (1) designed for a boat-like buoyancy body (2) made of solid material or inflatable or formed as a hollow body with inflatable air chambers therein. The drive module includes a seat (4) and a shaft (5) mounted in front of the seat and running in a transverse direction relative to the longitudinal direction of the buoyancy body (2). Paddle wheels (13) are mounted on the ends of the shaft (5). A profile (7) is hinged to the middle of the shaft (5) so as to be pivotable about its lower end region, which extends away from the shaft (5) upwards. A crankshaft (9) with drive wheel is mounted on the upper end region of the profile (7), and the cranks (10) of said crankshaft can be equipped optionally with pedals (11) for foot operation or with crank handles (12) for hand operation. As the cranks (10) are driven, the paddle wheels (13) are driven via a roller chain or a toothed belt, wherein the profile (7) can be latched in a pivot position for foot operation and can be latched in a position different from this for hand operation.

Abstract

The invention relates to a combination ski which is suitable for both skiing and sliding as well as for walking and climbing. The combination ski consists of a pair of skis (1) with a binding. The lower face of each ski can be used both as an adhesive surface as well as a sliding surface (3). For this purpose, the lower face is equipped with a turning plate (11), which forms a sliding surface (3) on one face and has an adhesive surface on the opposite face, with a structure that is designed for walking and climbing. The turning plate (11) is held in each use position in a mechanical and magnetic manner in a combination of magnetic and mechanical mountings on the lower face of the combination ski. Additionally, the front of the turning plate (11) can be equipped with a blade (12) which can be inserted into a slot in a step (4) on the lower face of the ski (1), and a recess (13) at the rear of the turning plate (11) can be placed over a triangular element (5) at the rear end of the ski in order to additionally secure the turning plate (11) on the lower face of the ski from slipping out of place.

Abstract

The combination ski comprises a riding and walking body (100) and a binding (200), which connects the shoe (300) to the device in a pivoting manner by means of the axis (108). The riding and walking body (100) has a main running surface (110), to which a partial running surface (120) is foldably connected about an axis (122) perpendicular to the longitudinal center line of the device. The different regions and sides of the main running surface (110) and of the partial running surface (120) are in such a condition or are coated in such a way that the device can be used for riding and sliding when the partial running surface (120) is folded forward and can be used for walking and climbing when the partial running surface (120) is folded back. The snow sporting device according to the invention can be easily and quickly switched from riding to climbing or vice versa without installing and removing additional parts. The combination ski can be implemented as a double-deck design, in that the combination ski has a sliding surface, which is formed by a lower deck as the only contact surface for sliding and climbing on hard snow, and from which sliding surface plank-like elevations laterally project above said sliding surface on both sides. With the outer edge areas of said elevations, the elevations then form an upper deck in order to increase the lift during riding in deep snow. The edges of the upper deck act as soft-snow edges.

Abstract

The skis of a pair of skis (10a, 10b) are movably connected to each other by at least one coupling system (140) secured on the skis in front of or behind the ski-binding area, in such a way that the longitudinal centre axes of both skis always remain parallel to each other during a longitudinal movement of one ski (10a) with respect to the other (10b), and such that the rotation of the running surfaces (11a, 11b) of both skis from the flat position of the running surfaces onto the edges and back again always takes place in the same direction of rotation and with the same angle. In this way, extreme forces that arise during skiing are taken up by both legs, the skis cannot cross each other, and no edge errors occur. The number of errors and therefore the number of falls is reduced, and there is less risk of an accident. Moreover, the learning process is made shorter, and a sense of success comes more quickly.

Abstract

The invention relates to a snow sport device consisting of a wide monoski (100), in the central region of which a binding platform (110) is installed. Two binding plates (120a-b) are mounted on said binding platform (110) in a longitudinally movable manner, a coupling device ensuring that the forward movement of one binding plate (120a) causes a rearward movement of the other binding plate (120b) or vice versa. Binding elements (130a-b, 140a-140b) of a known type are fixed on the binding plates (120a-b), said binding elements connecting the ski boots to the binding plates (120a-b). The connection of the binding platform (110) to the monoski (100) is designed such that the entire binding platform (110) together with both binding plates (120a-b) and both boots is released from the monoski (100) in the event of an impact. In this manner, a novel monoski system is provided which allows a movement of the boots during travel and thus achieves an additional dynamic component and which has a safety system that should contribute to a clear reduction of injuries in the event of dangerous impacts.
