Definitions

  • the invention relates to a locomotion device, in particular a motor-driven boat, with a catamaran-like body made of at least two parallel hose bodies arranged at a mutual distance and with a bottom arranged between them at a distance from the underside of the hose body (claim 1, 2 or 3).
  • Such a keel-less “vehicle” (boat, hull, gliding device or locomotive device or boat device) is to be designed equally for use, preferably rescue, on water and ice surfaces.
  • the boat device according to the invention is particularly suitable for rescue operations on waters, such as lakes, the water surface of which at least partially freezes over.
  • a rescue operation with only floating boats is usually no longer possible.
  • a rescue operation across a large ice surface is tedious and time-consuming.
  • This also applies to fire brigade operations from the mainland on an island with a frozen ice surface.
  • the bow region of the hull can be a further hose body that unites the two hose bodies or a rod (claim 4 or 5).
  • a ramp is formed in the bow area (claim 3), which makes the gliding safe and bumpless when moving from water to ice. This also means that gliding only on a frozen surface, driven by the propeller, is trouble-free.
  • the area delimited by the tube bodies is preferably occupied by a relatively solid base (claim 2) which is arranged at a distance from the sliding surface and is lowered relative to the center of the tube body.
  • This bottom is completely covered at the bottom by a second bottom part, which can consist of the same or a similar material as the tubular sleeves (claim 6).
  • Rubberized Kevlar fabric is very suitable. When driving on an ice surface, an air cushion forms between the raised (covered) hard floor and the sliding surface, which is used for buoyancy and, for example, for a higher one Speed (with the same drive power), or the ice is loaded with lower contact forces during the journey.
  • a frame for the air propeller propulsion preferably easily detachable, can be attached to the fixed floor.
  • a pivotable bottom flap enables rescuing people who have broken into ice surfaces without having to lift the victim over the hose body (claim 13).
  • the invention is based on the object of developing a motor-driven device of the type mentioned in such a way that it can be used easily, reliably and effectively for the situations mentioned at the beginning. It should be taken into account that difficult conditions can prevail in these operations, such as frequent changes of water and ice, pent-up or pack ice, strong or gusty wind or rubble with sharp edges of stones and the like.
  • the movement device must be able to be used under all weather conditions and should be able to control accident sites that are difficult to access precisely and quickly.
  • the hull Due to its increased lateral stability due to the clamping, the hull can
  • US-A 5,112,257 shows a vehicle which is said to be usable on water and on ice.
  • two tube bodies are inserted into a shell body and tied to this with straps. If the shell were to be flexible, this would mean that the distance between the hoses would change, thereby distorting the entire rod-shaped structure which was strapped to the hose bodies with the straps. If this is to be avoided, the shell as a whole has to be practically rigid, which makes driving on uneven ice extremely difficult and greatly impairs the controllability of the device. The load of the jacking and associated equipment must be absorbed directly by the flexible hose bodies.
  • the propulsive force of the drive is mainly directed only to the bow area, where the two tubular bodies converge, and is transferred there to the ends of the tubular body via a pneumatic tire.
  • the vehicle can hardly be steered on difficult, irregular ice surfaces, especially in difficult weather conditions.
  • FR-A 2,323,573 and US-A 6,148,757 show rigid, profiled boat hulls in which floating bodies are embedded or formed.
  • WO-A 01/12501 is based on another objective, namely to provide components that can be put together in a variety of forms in order to obtain vehicles of different lengths or widths with different drives for different purposes.
  • only one floor is provided, which consists of hollow-chamber plates which are firmly connected both at their edges which are adjacent to one another and at the edges adjacent to the tube body and are additionally stiffened by stiffening elements (there 88). The distance between the inflated tube bodies is determined by this floor.
  • Complicated and partially inflatable substructures can be attached to the undersides of the tubular body as skids, with a height approximately corresponding to the diameter of the tubular body itself. Wear-resistant guide strips attached directly to the underside of the hose body to increase the lateral stability and steerability are not provided.
