Canoe paddling exercise machine
First Claim
Patent Images
1. A canoe paddling exercise machine comprising a longitudinal frame;
- a flywheel mounted on said frame;
a seat on said frame on which a human subject is positioned for exercise, simulating canoe paddling motion by stroking an elongated handle against resistance on one or the other side of said frame, a flexible cord that attaches to said elongated handle, a pulley arm positioned at a front end of said longitudinal frame having an outer pulley over which said cord passes to said handle, and an inner pulley over which said cord passes from the outer pulley towards said flywheel;
means connected with said cord, said flywheel and said frame for rotating said flywheel in one direction when said handle is stroked aftward to provide resistance to said subject, and to retract said cord towards said flywheel when said handle is recovered forward between strokes; and
an axial pivot positioned on a forward end of said frame to permit said pulley arm to swing about a fore-and aft axis so that the outer pulley follows motion of the handle from one side of the frame to the other to produce a resistance during stroking of the handle that is directed substantially parallel to the frame axis, while the inner pulley remains positioned so that the cord passing therefrom towards said flywheel remains substantially in a predetermined path regardless of the position of the swingable pulley arm.

Abstract
An exercise canoe paddling machine has a frame, a pull cord that passes over an outer pulley and an inner pulley that are mounted on a pivotable pulley arm on the front of the machine, and thence under the machine to rotate a flywheel mounted beneath the frame. The cord is attached to an elongated canoe paddling handle. The pivoting pulley arm moves from side to side to follow movement of the paddling handle. The resistance that is produced during stroking of the handle is directed substantially parallel to the frame axis and to the same side thereof as the paddling handle.

7. An exercise ergometer machine which can be converted from a rowing exercise machine to a canoe paddling exercise machine, comprising a longitudinal frame, a flywheel mounted on said frame, a seat on said frame on which a human subject is positioned for exercising by simulating a rowing motion or by simulating a canoe paddling motion and stroking against resistance;
- a rowing pull handle;
an elongated canoeing handle;
a flexible cord that attaches to a desired one of said rowing pull handle and said elongated canoeing handle;
a rowing pulley arm that is removably affixable onto a front end of said frame, said rowing pulley arm having an upper pulley over which said cord passes to said rowing pull handle and a lower pulley over which said cord passes from said upper pulley towards said flywheel;
means connected with said frame, said flywheel and said cord for rotating said flywheel in one direction when said handle is stroked aftward to provide resistance to said subject, and to retract said cord toward said flywheel when said handle is recovered between strokes; and
a swingable paddling pulley arm assembly that includes a fixed member that is removably attachable onto the front end of said frame in substitution for the rowing pulley arm and that has an axial pivot portion fixed thereon, and a pivoting pulley arm member that has an outer pulley over which said cord passes towards said handle an inner pulley over which said cord passes from said outer pulley towards said flywheel, and a pivot member that mates with said axial pivot portion of said fixed member to permit the pulley arm member to swing about a fore-and-aft axis of the frame so that the outer pulley follows motion of said canoeing handle from one side of the frame to the other to ensure that the resistance 0 during stroking of the canoeing handle is directed substantially parallel to the frame axis while the inner pulley remains positioned so that the cord passing therefrom towards said flywheel remains substantially in a predetermined path regardless of the position of said swingable paddling pulley arm assembly. - View Dependent Claims (8)
