Definitions

  • the invention relates to a watercraft according to the preamble of claim 1.
  • the object to be achieved with the invention is to create a watercraft that is light and stable and can be disassembled and stored in a space-saving manner when not in use.
  • Damage to the parts protruding into the water can be prevented by two overload clutches, one of which responds to the direction of travel and the other to side obstacles.
  • 1-3 has three floating bodies 2 which are rigidly connected to one another by a frame 3 consisting of pipes and sleeves. To control this watercraft, there is a handlebar 4 with which the front floating body 2 can be pivoted.
  • a saddle 5 in the form of a conventional bicycle saddle is provided as the seat.
  • the frame contains a triangular first lying frame part connected to the floating bodies 2 with the tubes 6, 7 and 8. These tubes 6, 7 and 8 are each detachably inserted into a sleeve 9, 10 and 11.
  • a tube 25 extends vertically or inclined upwards towards the seat 5, into which a handlebar 27 rigidly connected to the handlebar 4 projects.
  • a joint 38 is connected to a horizontal axis 20, which runs transversely to the direction of travel, so that the front floating body 2 can perform a limited movement and thereby adapt to the swell.
  • a support strut 23 rigidly connected to the tube 25 is connected to a tube of the first frame part.
  • the pipe and sleeves are preferably made of light metal.
  • a pedal crank 16 provided with pedals 56, which is connected to a transmission gear 17.
  • This transmission gear 17 is located in a closed housing 26.
  • the gear 17 contains a pedal crank 16 connected large gear 18 which engages in a smaller gear 19.
  • Another headband 20, which drives a pinion 31 and a bevel gear 21 sits rigidly connected on its axis 29.
  • a bevel gear pinion 22 engaging in this is connected to a drive shaft 24 which projects obliquely downwards and carries a propeller 32 at its end.
  • the gear ratio is selected so that with a full revolution of the crank 16 per second on the propeller, a drive speed of about 1350 revolutions per minute arises.
  • To protect the propeller 32 it is surrounded by a drum 44 which is fastened to the horizontal tube by the linkage 46.
  • the three floating bodies 2 which are preferably identical to one another, are designed to be collapsible and preferably contain a collapsible plastic film which, when inflated, assumes the elongated torpedo shape shown in the drawing.
  • the floats 2 are each provided with a keel 40 on their underside. In the middle area, these floating bodies have a round cross-sectional shape, the diameter of which decreases towards the front and towards the rear.
  • the pipes and sleeves according to FIG. 6 - which only shows one of several plug connections - are designed to be pluggable into one another and are fixed by pins 30.
  • a flexible bracket 28 in the interior of the tube is connected to two coaxial pins 30, which are pressed outwards into bores 33 by a spring 41 located therebetween.
  • the pipe connection can be released without tools.
  • the frame can be easily separated and reassembled, the space requirement when disassembled is very small.
  • the floating bodies 2 also take up little space in the folded state. On in this way, a very space-saving design of this watercraft is possible when not in use, so that it can be easily transported and assembled at the desired location with little effort.
  • An embodiment variant consists in that at least one paddle wheel 35 is provided instead of a propeller, as can be seen from FIG. 4.
  • the drive between pedal crank 16 and paddle wheel hub 36 takes place via a chain 37.
  • the individual blades 39 can be inserted into the hub body and can be easily separated therefrom, whereby the space requirement in the disassembled state is small.
  • the formation of the blade wheel 35 is such that only the lower blade ends are in the water.
  • a curved protective hood 45 is provided at the top as protection against water splashes.
  • Another embodiment variant is that when using larger floating bodies, such a watercraft can be built as a tandem version, the seats being arranged side by side.
  • a child seat 48 can be attached to the support rod 25 for the handlebar 4, which can optionally be rotated.
  • a ladder 42 can be connected to the rear cross bar 8, which is preferably designed to be pivotable about the tube 8.
  • FIG. 7 to 9 show an embodiment variant of the drive device for the propeller.
  • a transmission gear which is moved by a pedal crank 16 in Rotation is offset.
  • a pedal 56 is rotatably attached to both sides of a cranked crank arm 54.
  • This pedal crank 16 is rotatably supported in two ball bearings 58 in the housing 50.
  • a first large spur gear 60 is non-rotatably connected to the pedal crank 16 and cooperates via a pinion 61 with a second spur gear 62 which is non-rotatably mounted on a shaft 64 which is rotatably mounted in the housing 50.
  • This spur gear 62 contains two ring gears 57, 59 with different diameters.
  • the one, larger ring gear 57 is in connection with a pinion 66, which is displaceable in the axial direction on a further shaft 68.
  • An axially displaceable sleeve 70 is connected in a rotationally fixed manner to this pinion 66 and carries a pinion 72 of larger diameter for switching over to two different transmission ratios.
  • a first bevel gear 74 is located on the same shaft 68 and is in drive connection with a second bevel gear 76. This second bevel gear 76 is rotatably supported in a bearing 78.
  • the assembly 86 of the propeller 23 is rotatably connected to the shaft 80. So that the assembly 86 together with the propeller 23 can be separated from the housing 50, there is a coupling device 81 which contains at least one bolt 90 which can be engaged and disengaged in a bushing 84 by means of a resilient actuating lever 92.
  • the lower end of the shaft 80 engages in a bearing of the assembly 86 and carries a bevel gear 96 which is connected to a further bevel gear 98 of the propeller shaft 100 and is rotatably supported in the propeller housing 44.
  • a change in the transmission ratio is carried out by pivoting a hand lever 110 which is seated on an axle 114.
  • An eccentric 116 protrudes from the axis 114 an axial displacement of the sleeve 70 and thus of the two pinions 66, 72, so that either the pinion 66 or the pinion 72 comes into engagement with one of the ring gears 57, 59 of the spur gear 62.
  • the housing 50 can be pivoted about a horizontal axis 120 which runs transversely to the direction of travel A. There are at least three different locking positions for the position of the housing 50 and thus the propeller, namely a normal first position with the notch 124 for driving the propeller 23 in the water, a second position with the notch 125 in shallow water and one third position with the detent 126, in which the propeller protrudes completely from the water.
  • An extension 122 protrudes from the housing 50 and is provided with at least three notches 124, 125, 126.
  • the other end of the tension spring 130 is suspended in a lever 133 pivotable about an axis 135.
  • the position of this lever 133 and thus the pretension of this tension spring 130 can be adjusted by means of an adjusting screw 132. In this way, the force can be selected which is necessary so that the latch lever 128, which is pivotable about an axis 134, can disengage from the catches.
  • this adjusting screw 132 the release force can be adjusted to the weight of the person on the watercraft.
  • Another overload protection device 145 is that if there is a side obstacle, the housing 50 together with the propeller 23 can pivot away to the side.
  • a horizontal shaft 140 on which a pipe section 142 is located.
  • This shaft 140 extends in the direction of travel B.
  • the housing 50 together with the propeller 23 can be pivoted about this horizontal shaft 140.
  • An arm 144 is rigidly connected to the pipe section 142, at the end of which there is a groove 146, into which - according to FIGS. 12 and 13 - the lug 148 of a coupling piece 150 of a claw coupling 151 engages.
  • This coupling piece 148 is rotatable about an inclined shaft 152 and carries an actuating wing 154 for manual reset.
  • This coupling piece 150 contains cams 160 which engage in corresponding recesses in a sleeve 162.
  • This sleeve 162 is loaded by a helical spring 164 and can be more or less pretensioned by means of a threaded sleeve 166. In this way, the force that is required so that the cams 160 disengage and the coupling piece 150 can pivot can be adjusted.
  • a force acting laterally on the housing 150 or on the propeller housing 44 exceeds a predetermined value, this causes the lug 148 to pivot out of the groove and the entire drive device, including the housing 50 and propeller 23, can therefore perform a pivoting movement in order to damage the Avoid drive device.
