Abstract

A recumbent bicycle having a single stroke linear type of pedaling wherein both legs protract and retract simultaneously so that a single push is made instead of alternating pushes. Various other adjustements are posssible to accomodate the length of a user legs and the degree of extension desired.

Claims

1. A recumbent bicycle with a single stroke linear pedaling system, consisting:

a. a frame comprising a sprocket and a one way sprocket;

b. a sliding frame in relation to said frame consisting;

ankle rests acting as pedals wherein said ankle rests being fixedly attached at either ends of a transverse bar that running perpendicular to said frame; and

a chain extension, said chain extension passing around a pulley rotationally attached to said frame and connecting to a bracket; and

a chain segment including first and second ends and two parallel bars situated parallel and at either sides of said frame, wherein said first end of said chain segment connected at a first location and said second end of said chain segment connected at a second location on said sliding frame, said chain segment partially wrapping around a one way sprocket such that forward stroke of said sliding frame causes rotation of said one way sprocket wheel in a forward direction resulting in forward motion of said bicycle, and back stroke of said sliding frame causes rotation of said one way sprocket in a reverse direction.

2. A recumbent bicycle as in claim 1 wherein:

said sliding frame slidingly connected to said frame by way of bearings;

said bearings being situated at either sides of said frame, under said frame and on top of said frame;

a pair of stoppers limit the extent of the sliding movement of said sliding frame;

a means is provided for positioning said stoppers along said frame to vary the extent of the sliding motion;

said means for positioning said stoppers being holes made into said frame.

3. A recumbent bicycle as in claim 2 wherein:

said means for positioning said stoppers are selected from the group consisting of a slit made into said frame and a rail made on the outside of said frame.

4. A recumbent bicycle as in claim 1 wherein:

an adjustment bracket adjusts the tension of said chain segment between said chain segment and said chain extension.

5. A recumbent bicycle as in claim 4 wherein:

said adjustment bracket being set between said chain extension and said chain segment.

6. A recumbent bicycle as in claim 4 wherein:

said adjustment bracket being set between said chain extension and said bracket.

7. A recumbent bicycle as in claim 1 wherein:

said parallel bars are shaped as <

channels enclosing said bearings.

8. A recumbent bicycle as in claim 1 wherein:

said connecting means being a stub and bracket.
