Abstract:
1. An amphibious float attachment apparatus for a bicycle comprising: a front receiver assembly removably and nondestructively attached to a front of said bicycle at a head tube, a plurality of brackets removably and nondestructively attached to a rear of said bicycle at a seat tube, a rear receiver assembly removably attached to said brackets on the rear of said bicycle, said rear receiver assembly comprised of an adjustable rear frame bar extending rearward from said plurality of brackets, a rotating receiver tube at a rearward end of said rear frame bar, said rotating receiver tube arranged perpendicular to said rear frame bar, a plurality of front and rear frame arms, each frame arm having a upper end and a lower end, the upper ends of said front frame arms removably attached to said front receiver assembly and the upper ends of said rear frame arms connected to said rear receiver assembly at the receiver tube, each said frame arm having a pivot bracket on the lower end, a plurality of rotating lift arms pivotally attached to said pivot brackets, whereby said rotating lift arms move in a longitudinally swinging arc in a direction along the length of said bicycle causing the ends of said lift arms opposite said pivot brackets to be raised above or lowered below said pivot brackets, said lift arms adapted to be locked in a desired position on said pivot brackets to prevent rotation, a pair of spaced-apart float frames consisting of one port float frame and one starboard float frame, said float frames coupled together, said float frames rotationally coupled to said lift arms whereby the movement of said coupled together lift arms and float frames causes all said lift arms and float frames to move simultaneously and in the same direction resulting in a change in height of said float frames, said rotationally coupled lift arms and float frames are adapted to allow said float frames to remain oriented in an upright position, said float frames spaced apart at sufficient distance to allow stability on water and said bicycle and rider to operate between said float frames over land or water without interference with any part of said attachment apparatus, and; a plurality of floats removably attached to the underside of said float frames, each float frame having at least one float, for buoyancy on the water.
