FR2645113A1 - Nautical craft allowing a land-going cycle (bicycle or moped) to move over the water without any alteration or adaptation - Google Patents

Abstract

The invention relates to a device which is equipped with one or two floats, tubes for supporting the cycle, driver roller connected to propulsive blades or screws, allowing rapid fitting of a bicycle or moped and allowing it to move over the water. Separation of the nautical craft and the cycle is also rapid. The assembly system operates using the fastenings 12 under the handle bars, for the front, and at the saddle tube under the saddle for the rear part. The rudder is fixed onto the front tyre 5 and 20. The cycle operates on water identically to its operation on land.

Description

 TITLE OF THE INVENTION.

NAUTICAL GEAR @ PERME @ AS LONG AS A TERRESTRIAL CYCLE (bicycle or moped) MOVES ON THE WATER WITHOUT ANY MODIFICATION.

 THE GOAL.

This machine allows a cyclist or a moped to ride on the water with his bicycle or his personal moped without the need for any modification or adaptation of any of these - @@ ci.

Enter the bicycle or moped for a short time
The speed of movement is proportional to the speed of totalization of the rear of the bicycle or moped. This nautical device for any bicycle or moped, light and simple in structure (tube or aluminum bars, rollers and two lateral floats) inexpensive allows great freedom of use;
21; DESCRIPTION.

The description refers to the attached sketches. It is an aquatic leisure device; it differs from the previous ones (example

been estimated to stably support a cycle or moped in running or slightly agitated water: example: descending small rapids from a river without danger of turning over. However, this width can be considerably reduced (just the width of the rollers), in measurement or we are moving towards a sport or competition machine with a racing bike. The extreme evolution being the variant with 1 float and 2 side drive rollers; (sketch appendix J.

Claims (3)

 ---- R E V E N D I C A T I O N S  1). The nautical device allowing a terrestrial cycle (bicycle or moped) to move on water without any modification is characterized # by fixing tubes (6) and (16) in light alloy or hard plastic of the cycle on a frame (4), (10), (11) connecting the floats and supporting the drive rollers on which the rear wheel of the cycle or moped rests. Steering is ensured by a rudder fixed to the front wheel. 2). Nautical craft according to claim (1) characterized in that the two lateral floats (17) are replaced by a float (fig. 3), of the windsurfing type, and the central blade roller (7), (13) by two side rollers. 3). Nautical craft according to claim (1) characterized in that the propulsion member is no longer a paddle roller (7) and (13) but two propellers wedged at the two ends of two shafts, the other end of which is fixed to the rear roller (9) by a pinion with angle transmission.
