A water machine is disclosed, comprising a fixed frame (1), on the back of which a propeller (2) is situated, and a mobile frame (5, 50) situated on the front of said fixed frame (1), which can have three positions, of which one is a non-operating contracted position, and two are operating positions that allow the user to keep his back in vertical or horizontal position, respectively.

Description

  • The present patent application for industrial invention relates to a water machine with propeller actuated by electrical motor or pedals.
  • The machine of the invention has been devised in the water rehabilitation sector and is an absolute novelty in the field of aquatic gym machines with pedals, since it can be disposed in different ways to allow the user to pedal in different positions.
  • Such a machine has been devised both for sports and rehabilitation purposes.
  • In view of the above, the water machine can be provided with an electrical motor adapted to drive the propeller into rotation or with pedals and transmission between propeller and pedals.
  • In fact, it must be noted that pedaling in water tones up legs and glutei and optimizes the functioning of the cardiovascular system; moreover, pedaling in water is also recommended for rehabilitation purposes because, due to hydrostatyc push, the weight of the body on joints is lower, thus eliminating stress and loads that may be harmful in some subjects.
  • More precisely, pedaling in water is recommended for people who need a rehabilitation period, for example, after a joint surgery.
  • In these cases, physical activity in water can be an efficacious integration to traditional rehabilitation techniques.
  • FR 2 618 405 discloses an aquatic pedal machine comprising a rudder and a float provided on the back of the frame. Therefore, such a machine is impaired by problems related with floating, stability, comfort and handling.
  • FR 796 986 discloses an aquatic pedal machine comprising a rod with basically Y-shaped structure with two divaricated arms at the ends of which two floats are connected. Such a machine is not configurable and cannot change its position.
  • DE 196 22 162 discloses an aquatic pedal machine comprising a compass-like frame hinged to a fixed frame.
  • DE 24 10 352 discloses an aquatic pedal machine wherein telescopic sliding of two frames is provided.
  • The purpose of the present invention is a water machine with propeller that occupies a very small volume when it is not used.
  • A further purpose of the present invention consists in a water machine with propeller that, in addition to achieve the aforementioned purpose, allows the user to keep his back in vertical or horizontal position during use.
  • More precisely, such a need has arisen in order to provide maximum versatility of the machine of the invention, which can be used for rehabilitation purposes both by individuals who need to pedal with their back in erected position and individuals who need to pedal while lying down with their stomach facing downwards.
  • The water machine with propeller, according to the invention, comprises a fixed frame, on the back of which a propeller is situated, and a mobile frame situated on the front of said fixed frame, which can have three positions, of which one is a non-operating compact position, and two are operating positions that allow the user to keep his back in vertical or horizontal position, respectively.
  • Moreover, said machine comprises a pair of rods - a front rod and a back rod - respectively fixed to the mobile frame and fixed frame, where the floats that make the machine float are fixed.
  • The front rod is fixed to the mobile frame, is free to rotate with respect to a basically vertical axis and comprises a rudder.
  • For explanatory reasons, the description of the water machine according to the present invention continues with reference to the attached drawings, which only have illustrative, not limiting value, wherein:
