[0060] DESCRIPTION OF THE PREFERRED EMBODIMENT

[0061] With reference to the abstract of the preferred embodiment of the new Paralympics Cycling Watercraft and with reference to the drawings, and in particular to fig. 26 and 27 thereof, the preferred embodiment, of the new Paralympics Cycling Watercraft constructed in accordance with principle and concept of the present Invention, generally designed by the reference numerals 1 to 57, will be described. These preferred embodiments are for air and water propelled flat catamaran.

[0062] The present invention, the new Paralympics Cycling Watercraft is a system comprised of plurality of individual components, in their broadest context; such components are housed in segments. The components are individually configured and correlated with respect to each other to attain the desired objectives.

[0063] Essentially and in summary, the present invention, the new Paralympics Cycling Watercraft as in fig. 1, comprises flat catamaran circle 1, horizontal structures circle 2, primary motion transmission circle 3, vertical cycling structures circle 4, cycling handle circle 5, motion transmission and transformation mechanism circle 6, cyclist stool circle 7, twin arm gearbox circle 8 propeller shaft housing circle 9, propeller shaft circle 10 and air propeller circle 11. For water propelled catamaran, the propeller shaft housing is constructed vertically downwards circle 46 in fig. 21 to hold the submersible gearbox in water.

[0064] To attain this, two boats are constructed and joined together by marine block board as illustrated in fig, 2, 3 and 4. A horizontal cycling structure circle 15 in fig. 5 is fabricated and fastened on the ready positioned bolts on the floor of catamaran as illustrated in fig. 6.

[0065] A cycling structure circle 4 comprising cycling handle circles 5, sprockets circle 17 and 19, chain circle 18 as in fig. 8 and 9, is constructed and fitted on horizontal structure circle 2

[0066] The multi linear wheels which are the integral components of the invention for power and motion sustainability are built. To attain this, a solid wheel circle 21 in fig. 10 is cut from a thick steel plate and shaped or formed and shaped. A tee bar is inverted and bent into a circle and the joint welded. The up stand flange is cut into teeth to form tee bar sprocket circle 22 in fig. 11. A steel plate is bent into corrugation circled and the joint welded to form a corrugated rim circle 23 in fig. 12. The internal corrugations are drilled and fasten on spokes circle 24 in fig. 12. The outer corrugations of the rim are drilled and fasten on to the solid wheel circle 21 in fig. 13. The spokes are harnessed by hub circle 25. The assembling together of the 4 wheels namely the hub, corrugated rim, solid wheel and inverted tee bar sprocket, forms a multi linear wheel of a side view in fig. 13 and profile view in fig. 14 which is installed on the vertical structure circle 16 in fig. 19.

[0067] A plate channel circle 30 in fig. 16 is constructed and attached on two sprockets circle 27 and 31. This plate channels are then fixed on the arms of the gearbox circle 8 in fig. 17 and 18. The multi linear wheel circle 34 in fig. 19 is then fixed on the vertical structure circle 16 in fig. 19. The bracket circle 26 in fig. 15 is fabricated and fixed on the same structure circle 16 for the tension of primary chain circle 36. With the installation of the plate channels circle 30 on the arms of the gearbox, secondary chains circle 33 in fig. 19, are aligned to sprockets circle 27 and 31 with the input sprocket circle 32. This is to make multi linear wheel to run the secondary chain at right angle in order to remove the cycling friction.

[0068] This arrangement of double multi linear wheels in motion transmission is to stabilize flat catamaran on water. The double motion transmission has to be received by one gearbox that has to increase the speed and convert horizontal motion to vertical or longitudinal motion.

[0069] To attain this, as in fig. 20, the gearbox circle 8 is constructed with double arms and with internal horizontal transverse shaft circle 39, fitted with external sprockets circle 32 to receive double motion from the multi linear wheels circle 34 via secondary chains circle 33. The gearbox is therefore fitted with components such as sprockets circle 38 and 41, advanced chain circle 40 horizontal transverse shaft circle 42, bevel gear circle 43 and vertical pinion circle 44. For water propelled gearbox circle 8 in fig. 21, a vertical propeller shaft housing circle 46 is constructed downwards from gearbox and its internal components comprising shafts and gears, picks motion from pinion circle 44 and transmit to the propeller circle 50 and a thrust is produced to move flat catamaran forward.

[0070] For the air propelled, propeller shaft housing circle 9 is constructed longitudinally backwards and therefore propeller shaft circle 10 picks motion longitudinally from pinion circle 44 in the gearbox circle 8 direct to the propeller circle 11 , where a thrust is produced to moved catamaran forward.

[0071] The double cycling Paralympics Cycling Watercraft as in fig. 24, the cycling system for water and air propelled, is similar to single cycling system except the cyclists area will have to be widened to accommodate two cyclists and the main drive horizontal transverse shaft circle 20 as in fig. 24, will have to be made longer.

[0072] The double and single cycling air propelled Paralympics Cycling Watercraft will have on board breaking system comprising a handle circle 52, fulcrum circle 53, lever circle 54, link rod circle 55 and resistant plate circle 56. The puling of the handle circle 52 up, will make the lever to rotate at
