Abstract
A vehicle is provided that includes a frame having a drive member supported for rotation thereon. A handlebar is supported for pivotal movement relative to the frame. A drive mechanism is provided on the frame that is configured to rotate the drive member in a first rotational direction when the handlebar is pivoted in either a first direction using a push-stroke or a second direction using a pull-stroke.
Claims18
A vehicle comprising:
- a frame including a drive member supported thereon for rotation;
- a handlebar supported for pivotal movement relative to the frame;
- and
- a drive mechanism provided on the frame that is configured to rotate the drive member in a first rotational direction when the handlebar is pivoted in either a first direction using a push-stroke or a second direction using a pull-stroke, the drive mechanism including:
- a first driven axle having a first driven sprocket supported thereon;
- a second driven axle having a second driven sprocket supported thereon;
- and
- a chain that extends around portions of the drive sprocket, the first driven sprocket, and the second driven sprocket.

A vehicle comprising:
- a frame including a first wheel supported between a pair of forks that, in turn, is supported for rotation within a head tube of the frame and a second wheel supported for rotation on the frame;
- a handlebar supported for pivotal movement within a support sleeve that, in turn, is connected to the pair of forks for rotation within the head tube;
- an arm-powered drive mechanism provided on the frame, wherein the arm-powered drive mechanism is configured to rotate the first wheel in a first rotational direction when the handlebar is pivoted within the support sleeve in either a first direction using a push-stroke or a second direction using a pull-stroke;
- and
- a leg-powered crank mechanism provided on the frame, wherein the leg-powered crank mechanism is configured to rotate the second wheel in the first rotational direction independent of the first wheel, wherein the arm-powered drive mechanism includes a drive sprocket supported for rotation with the handlebar, a first driven sprocket supported on a first driven axle and a second driven sprocket supported on a second driven axle, and a chain that extends around the drive sprocket, around the first driven sprocket in a first rotational direction, and around the second driven sprocket in a second rotational direction.

A drive mechanism for a vehicle including a frame and a wheel that is supported for rotation relative to the frame, the drive mechanism comprising:
- a handlebar that is adapted to be supported relative to a frame of a vehicle for movement in first and second directions;
- a drive sprocket that is connected to rotate in first and second rotational directions when the handlebar is moved in the first and second directions, respectively;
- a first driven axle having a first driven sprocket supported thereon for rotation therewith;
- a second driven axle having a second driven sprocket supported thereon for rotation therewith;
- and
- a chain that extends around portions of the drive sprocket, the first driven sprocket, and the second driven sprocket;
- wherein one of the first and second driven axles is adapted to rotatably drive a wheel of the vehicle.
