Definitions

  • the invention relates to a watercraft, in particular for use by individuals, with two buoyancy bodies, pedals, crank rods and a seat, the buoyancy bodies being two hulls which are connected to one another by means of a collapsible linkage such that their longitudinal axes are aligned approximately parallel to one another .
  • the linkage has a frame head that a fork is attached to the underside of the frame head, which fork has two fork arms, which are penetrated at their lower ends by an axis to which the pedals are attached at the ends by means of the crank rods are and that a paddle wheel is attached between the fork arms approximately in the middle of the axis and firmly connected to this.
  • the linkage preferably consists of four crossbeams, each of which has a hull go out and meet in a frame head.
  • this arrangement above offers the advantage of quick insertion and release of the linkage connections, which all converge at a central point, the frame head.
  • the trusses protrude upward from the plane described by the top of the hulls.
  • the advantage of this pyramid-shaped arrangement is in particular that the frame head can take such a position comparatively high above the water surface.
  • the frame head is therefore suitable in this arrangement for receiving a seat. Controlling and changing the direction of travel is particularly easy when the seat is located at a greater height above the water surface, so that one of the two hulls can be immersed deeper by shifting the weight. Since this increases the water resistance of this hull, control is possible by simply shifting your weight.
  • connections between cross members and hulls and / or between cross members and frame head are detachable connections, in particular screw, plug or clamp connections.
  • This design of the necessary connections offers the advantage of the fact that the entire watercraft can be dismantled quickly. With a suitable execution of the connections in question will be possible without special tools.
  • the watercraft according to the invention can therefore be disassembled quickly and easily and carried on or in a car to a suitable water surface.
  • a saddle is preferably attached as a seat on the top of the frame head. This arrangement offers the advantage of stable attachment of the seat, which is supported at the point where all forces acting on the watercraft meet.
  • the frame head will generally be located approximately vertically above the center of gravity of the vehicle.
  • the design of the seat as a saddle also offers the advantage of an upright and fatigue-free sitting position.
  • the saddle has a handle on its front. It allows the person sitting on the saddle to take a subjectively and objectively stable sitting position.
  • the paddle wheel consists of an approximately circular disk which is fixedly connected to the axle and penetrated by the axle in the center, and which are firmly connected to the disk in such a way that they are radial from their center point outwards.
  • a rudder blade is placed between the hulls soaking in the water. Its pivoting takes place and is determined by a handlebar or knob that can be reached by the user sitting on the saddle, the pivoting or twisting of which changes the position of the rudder blade.
  • the handle can also be used for control.
  • the movement is transferred to the rudder blade in any way, e.g. through a cable, a linkage, a shaft.
  • the two hulls are directly connected to one another by further cross members.
  • the watercraft according to the invention consists of two hulls (1) aligned parallel to one another, which are connected to one another via linkages (2).
  • it consists of four crossbeams (3), each starting from a fuselage (1) and meeting in a frame head (4).
  • this frame head (4) is provided with a saddle (5).
  • a handle (6) is in turn attached to this saddle (5).
  • the fork (7) is located below the frame head (4). This is penetrated at its lower ends by an axis (8) to which the pedals and the paddle wheel drive are attached.
