Definitions

  • the present invention relates to a watercraft propellable by human force and can be applied to recreation, sports training or even rehabilitation, for both healthy people and disabled.
  • the frame usually has a gutter-shaped portion for accommodating an inflatable element, so that the immersed part of the machine generally has a density lower than that of water. Therefore, when the user sits astride the bottom of the frame and floats in the water, the center of gravity of the floating assembly whose submerged portion is subject to buoyancy is raised relative to on the surface of the water, which reduces the stability of this set. Because of this reduction in stability, the movements exerted by the user may cause it to tilt. This problem arises with great acuteness in the case where the machine is used by disabled members of the lower limbs and during re-education sessions during which the patient must perform exercises that he has great difficulty in controlling.
  • the invention therefore firstly aims to eliminate these disadvantages.
  • a machine of the aforesaid type provided with a tubular frame comprising in its lower part at least one water access orifice and, in its upper part, at least one air passage orifice or vent , provided so that when the machine is disposed in the water, the frame fills at least partially with water, the water contained inside the frame then playing the role of a ballast.
  • the vent may be equipped with closure means so as to allow the user to control the amount of water inside the frame, in particular for the purpose of adjusting the position of the center of gravity of the floating assembly relative to the center of rotation of the frame.
  • these propulsion means may consist of a flexible fin or fin attached to one of the two uprights of the frame, substantially mid-height thereof and extending outwardly of the frame, in a plane passing through a axis of rotation of the frame, in the vicinity of said cable.
  • the watercraft comprises a rigid tubular frame having an inverted ⁇ shape which comprises a central portion 1 substantially circular open in its upper part and whose two ends are bent and extended by two respective wings 2, 3 which are extend outwardly coaxially relative to each other and which each carry a mortise assembly profile 4, 5.
  • These assembly profiles 4, 5 each comprise a vent E 1 , E 2 allowing communication of the interior volume of the tubular frame with the outside. These vents can be closed by a shutter O 1 , O 2 for example needle type.
  • This tubular frame may be made of a light material such as a plastic material.
  • the central portion 1 of the tubular frame comprises in its lower part 6 an area covered by a flexible pad 7 in the form of a hemicylindrical shell for example of closed-cell expanded plastics material.
  • This lining serves as a seat for a user 8 disposed astride the seat.
  • the zone of the lower part 6 of the frame which is opposite to the lining 7 is provided with three water-passing orifices 8, 9, 10. These orifices 8, 9, 10 are intended to allow the filling of the tubular frame by means of water when it is at least partially immersed. This filling which is carried out by expelling the air contained by the vents E 1 , E 2 makes it possible to obtain a "ballast" of the watercraft.
  • the water level inside the frame can optionally be adjusted to suit the user through the shutters O 1 , O 2 equipping the vents.
  • Each of the floats 11, 12 is equipped with two handles 15, 16 respectively disposed on either side of its assembly profile 13, 14.
  • Each handle 15, 16 is constituted by a right angle bent round which extends in the concavity of the circular form of the float 11, 12 between one of its ends and its central region.
  • each of the floats 11, 12 is further provided at its two ends with two respective protuberances 19, 20 each provided with a through hole, for example a link.
  • the frame comprises in its central region, substantially at half height, two radial attachment studs 21, 22 on each of which can come engage and fix, removably, a flat fin 23 elastically deformable which extends in a plane (in principle horizontal) perpendicular to the general plane of the frame.
  • the fin 23 has a cardioid shape.
  • this fin 23 on the frame is effected by means of a yoke 24 in which is engaged one of the two tenons 21, 22.
  • the two wings of the yoke and the tenon are each crossed by two bores arranged so that in the assembled position of the tenon 21, 22 in the yoke 24, there are two through passages in which can be engaged two fastening pins optionally secured to one another to one of their ends.
  • the frame When it is launched, the frame fills at least partially with water that enters through the holes and flushes a corresponding volume of air through the vents until it floats on the water thanks to the floats 11, 12, the central part 1 of the frame which is immersed then plays the role of a boat keel.
  • the first mode of propulsion is to bow forward in relation to the horizontal and to pedal like a cyclist or to beat legs like a swimmer.
  • the fin 23 is not used.
  • the second mode of propulsion is to cause, by alternately tilting forwards and backwards and exerting a force on the handles 15, 16, a rotation of the frame in its plane about its axis of rotation R.
  • the figure 2 illustrates a position of the user tilted backwards.
  • the fin elastically deforms upward by accumulating potential energy that it releases then returning to its original position by exerting a force of propulsion of the machine forward.
  • the fin 23 When tilting the user forward under the effect of water resistance, the fin 23 deforms downward to the illustrated position figure 3 then returns to its original position by exerting on the machine a thrust effort forward.
  • the user can adjust the water level inside the frame so as to bring as close as possible the center of gravity of the set user / machine, the center of rotation of the machine.
  • the tubular frame 30 of the watercraft 31 is made of two half-shells 32, 33 of C-shaped cross-section, joined to one another at their lateral edges, by means of screws 34 passing through through chambered holes whose chambers are intended to receive the heads of the screws 34 and / or the nuts.
  • the tubular frame 30 engages at its ends in cavities provided in the floats 35, 36, the locking being provided by a locking means such as for example one or more screws.
  • these floats 35, 36 have on one side a curved shape 37 which extends outwardly from the frame 30 and, on the opposite side to the previous one, a serrated shape 38.
  • This serrated shape 38 comprises two notches 39, 40 respectively located on either side of a central portion 41 having the cavity 42 in which engages one end of the tubular frame 30 ( figure 7 ).
  • each float In a vertical plane perpendicular to the longitudinal median plane of symmetry of the frame 30, each float is in a slightly flattened oval shape ( figure 6 ).
  • the convex shape 37 has two indentations 39 ', 40' located in the extension of the indentations 39, 40.
  • the two floats 35, 36 have identical shapes and each further comprise through recesses 41, 42, 43, 44 vertically oriented which each delimit with the rim of the float a gripping handle 41 ', 42', 43 ', 44' .
  • the central portion of the tubular frame comprises an upper zone covered by a flexible liner 45 consisting of a shell having in an upright transverse plane an inverted U-shaped section.
  • the tubular frame has at least one water passage orifice 46 intended to allow a filling of the frame when it is at least partially immersed.
  • the tubular frame 30 comprises two coaxial through holes 47, 48 oriented perpendicular to the longitudinal plane of symmetry of the frame 30. These two bores 47, 48 are intended to ensure the passage of two respective coaxial drive axes 49, 50 ( figure 9 ).
  • These two drive shafts 49, 50 are rotatably mounted on a rigid structure 51 housed inside the frame 30.
  • levers 52, 53 are intended to be manually actuated by a user according to an alternating tilting movement between an anterior position in which they each engage each other in a corresponding recess 39, 40 of the float 36 at a posterior position. in which they are outside the indentations 39, 40.
  • the bent form of the levers 52, 53 is intended to extend as far as possible forward the end of the levers that serve as handles to the user.
  • This provides an ergonomic arrangement allowing the user to make the most of the strength of his arms.
  • each operating lever 52, 53 is provided with a knob 54, 55 of spherical shape, used as a hand grip.
  • the frame 30 comprises two coaxial holes oriented parallel to the holes 47, 48, which are intended to ensure the passage of two respective coaxial drive axes 56, 57 in a similar arrangement to that shown figure 9 .
  • the attachment of the flippers on the drive shafts 56, 57 is performed by screwing, by means of fixing means allowing adjustment of the orientation of the flippers.
  • the two drive shafts 49, 50 - 56, 57 located on the same side of the longitudinal plane of symmetry of the frame 30 are coupled to each other by a transmission mechanism of conventional type.
  • this mechanism involves a transmission by cables and pulleys.
  • the rigid structure 51 comprises a P beam having a bent shape corresponding to the bent form of the frame 30, here a substantially trapezoidal shape open at the large base.
  • This beam P carries, at each of the pairs of holes 47, 48, a transverse axis 60 which extends coaxially with the drilling torques 47, 48, on either side of the beam P.
  • the ends of this axis 60 which protrude from either side of the beam P constitute trunnions on which engage two respective tubular drive shafts 49, 50 each carrying inside the frame 30 a double drum T1, T2 - T3, T4 on which are fixed and wind the ends of two cables C1, C2 - C1 ', C2'.
  • tubular drive shafts 49, 50 - 56, 57 are secured at their ends which emerge from the frame 30 respectively to the actuating levers 52, 53 and the fins 58, 59 via a cylindrical hub 61 , 62 - 61 ', 62' for example of plastic.
  • the two pairs of cables C1, C'1 - C2, C'2 (one pair per side of the beam P) are guided by two pairs of pairs of rollers PC1, PC2 respectively disposed at of the angular region of the trapezoidal shape of the beam P.
  • the figure 10 shows a pair of pairs of PC1 pebbles.
  • rollers 65, 66 - 67, 68 of each pair of pairs of rollers PC1, PC2 are pivotally mounted about a transverse axis 70 passing through the beam P and extending on both sides thereof to constitute two pins.
  • the tilting of a lever 52, 53 in one direction causes the rotation of a corresponding first drum T1, T2 and consequently the winding of one of the cables C1 of this drum T1, T2 and the unwinding of the second cable C2 of the drum T1, T2.
  • the winding of the first cable C1 generates on the second drum T3, T4 associated with the palm 58, 59, located on the same side, a running of this cable C1 with a rotation drive of the second drum T3, T4 and corresponding palm 58, 59.
  • the second cable C2 then undergoes a winding on the second drum T3, T4 and unwinding on the first drum. Tilting in the opposite direction of the lever 52, 53 will cause an inverse action of the previous one with rotation in the opposite direction of the fin 58, 59.
  • the flippers can be directly actuated by the user by means of straight levers 70, 71 equipped with handles directly fixed to the hub 61 ', 62' serving for fixing the fins 58, 59.
