Definitions

  • the present invention relates to a water­craft provided with propelling devices for propell­ing it in water.
  • watercrafts are already commercial­ly available which consist of a floating body thereon a frame is supported adapted to receive the user and provided with pedals or the like elements which drive a propelling element, such as a propeller.
  • the main object of the present invention is to overcome the above mentioned drawbacks, by providing a novel watercraft including propelling elements for propelling it on water which is very stable and which, moreover, is able of advantageously hydromassaging the user.
  • Another object of the present invention is to provide such a watercraft which has very reduced size and weight, while providing very good floating characteristics.
  • Still another object of the present invention is to provide a watercraft which is very reliable in operation and which, moreover, can be constructed start­ing from easily available materials and has a very reduced cost.
  • a watercraft provided with propelling elements, characteriz­ed in that it comprises a submersible frame to the top ends of which there are coupled floating elements, said submersible frame including, at the front portion thereof, gripping means to be gripped by the user and, at the central portion thereof, a saddle arranged at a lower level than said floating elements in order to hold the center of gravity of said watercraft under the water surface, propelling devices being moreover provid­ed for propelling said watercraft on water.
  • the watercraft provided with propelling devices for propelling it on water comprises a submersible frame, indicated overally at the reference number 1, which has a substantially V-shape, like a bicycle frame.
  • floating elements which may be formed as hulls, indicated at 10 in figure 2, or as balls, indicated at 11 in figure 2, or in any other suitable ways.
  • the mentioned floating elements can be affixed to the top ends of the frame 1 so as to cause said frame to be completely submerged as the watercraft is used.
  • This characteristic is very important since it provides the watercraft according to the invention with a great stability.
  • the frame 1 is provided with gripping means 15 to be gripped by the user and, at the middle region of said frame 1, there is provided a saddle 20 which is arranged at a lower level than the floating elements so as the center of gravity of said watercraft will be held under the water surface, thereby further improving the use stability of said watercraft.
  • the watercraft frame 1 is moreover provided with propelling devices which, according to a preferred embodiment, may consist of conventional pedals adapted to drive a paddle, or propeller, 31 arranged at the rear of the frame and rotatable by the pedals in order to cause the watercraft to be displaced.
  • propelling devices which, according to a preferred embodiment, may consist of conventional pedals adapted to drive a paddle, or propeller, 31 arranged at the rear of the frame and rotatable by the pedals in order to cause the watercraft to be displaced.
  • the propeller 31 may be replaced by a hydrojet type of driving assembly including, as shown in fig. 3, an internal combustion engine 40 arranged in the inside of one of the floating elements, or suitably submerged, said engine driving a hydrojet impeller indicated at 41 for propelling the watercraft.
  • a hydrojet type of driving assembly including, as shown in fig. 3, an internal combustion engine 40 arranged in the inside of one of the floating elements, or suitably submerged, said engine driving a hydrojet impeller indicated at 41 for propelling the watercraft.
  • the watercraft will provide further advantages :in fact , in the first embodiment, with the user pedalling a hydromassage effect will be obtained due to the relative movement of the user legs pedalling in water, in combination with the displacement of the craft.
