Abstract
Amphibious vehicle having a pedal assembly coupled to propelling devices. On land the vehicle is propelled by at least one wheel driven by the pedals. The wheel has vanes for use in water. Floats keep the vehicle afloat in water. The pedal assembly is adjustable on the vehicle frame to raise them above the water when afloat. In a second embodiment a separate propeller machanism is coupled to the pedal assembly for use in water.
Claims8
Amphibious vehicle with a bicycle or motorcycle frame, front and rear wheels, the rear wheel comprising a hub, a rim, and resistant elements extending between the hub and the rim and formed as blades at one end, a pedal assembly having a pedal shaft coupled to the hub of the rear wheel which propels the vehicle when the pedals are operated;
- a chassis for each of the wheels having at least one lateral resistant arm having at its end a float to keep the vehicle afloat, each of the said arms being articulated to permit it to be folded sideways towards the wheel when the vehicle is used as a land vehicle;
- and adjustable means mounting the pedal assembly on the chassis frame with the rotary axis of the pedal shaft in one of a lower and an upper position depending on whether the vehicle is to run on land or on water, respectively, said adjustable mounting means including a bush rotatably mounting the pedal shaft, and a part of "U" shaped cross section, said frame having an enlargement engaging said U-shaped part and extending between two end stops on the frame;
- and a bolt to fix the position of the pedal-shaft-mounting bush on said frame enlargement, the pedal assembly having tensor to adjust the tension on said chain to ensure proper coupling of pedal shaft to the rear hub.
Amphibious vehicle with a bicycle or motorcycle frame, front and rear wheels, the rear wheel comprising a hub, a rim, and resistant elements extending between the hub and the rim and formed as blades at one end, a chassis for each of the wheels having at least one lateral resistant arm having at its end a float to keep the vehicle afloat, each of the said arms being articulated to permit it to be folded sideways towards the wheel when the vehicle is used as a land vehicle, a pedal assembly having a pedal shaft mounted on a part having a pivotal axis parallel to the said shaft and pivotal on the vehicle frame, the part being pivoted to permit the raising and lowering of the pedal shaft in relation to the frame of the vehicle and adjustable means mounting the pedal assembly pivotal part on the vehicle frame with the rotary axis of the pedal shaft in one of a lower and an upper position depending on whether the vehicle is to run on land or on water, respectively;
- the pedal assembly including on the shaft two parallel discs, one transmission chain coupling one disc to the rear wheel hub, a propeller, and a second chain coupling the second disc to the propeller to propel the vehicle when the pedal shaft is operated.
