Abstract
An alternative drive device for a bicycle comprising a drive wheel assembly having two drive shafts and a drive wheel with dual rachet assemblies therein; vertical frame for mounting the drive wheel assembly in frictional engagement with the bicycle front tire and connected to a first horizontal bar; vertical frame extension connected to said first horizontal bar and a second horizontal bar, and attachable to a bicycle's handle bars; a pair of handles slidably mounted on the second horizontal bar, attached to a cable and pulley system that engages the drive wheel assembly, and capable of driving the device by reciprocal motion along the second horizontal bar wherein the motion of the handles causes the drive wheel, and hence the bicycle's front tire, to rotate.
Claims7
An alternate drive device for a standard bicycle without mechanical modification to the bicycle comprising:
- a drive wheel assembly adapted for rotatably frictionally engaging a bicycle front wheel;
- means for supporting the drive wheel assembly;
- means for removably attaching the support means to a bicycle;
- a bar attached to the support means, having at least one handle slidably mounted thereon for reciprocal motion along an axis of the bar;
- and,
- dynamic interconnection means linking the said at least one handle with the drive wheel assembly;
- wherein the interconnection means converts reciprocal motion of the at least one handle along the bar into rotary motion of the drive wheel assembly, thereby driving the bicycle.
An alternative bicycle drive device comprising:
- a drive wheel adapted for rotating frictional engagement with the front wheel of a bicycle;
- first and second axles supporting the drive wheel;
- first and second ratchets having opposite rotational engagement connecting the first and second axles respectively to the drive wheel;
- a first horizontal bar;
- first and second frame members connected to the first horizontal bar in spaced relation for rotatably supporting the first and second axles proximate the drive wheel;
- third and fourth frame members connected to the first horizontal bar in spaced relation for rotatably supporting the first and second axles distal the drive wheel;
- a second horizontal bar connected to the first and second frame members;
- an endless cable helically wrapped clockwise for a plurality of turns about the first axle and helically wrapped counterclockwise for a plurality of turns around the second axle, the endless cable engaging each axle whereby longitudinal motion of the cable imparts rotational motion to the first axle and opposite rotational motion to the second axle;
- first and second handles slidably mounted to the second horizontal bar, the first and second handles connected to the endless cable for oppositely directed reciprocating motion;
- means for attaching the first and second frame members to the handlebars of a bicycle;
- and,
- sheave means mounted to the first and second horizontal bars for supporting the endless cable.
