Abstract
An elliptical motion rowing machine includes a frame, a linkage assembly movably mounted on the frame in such a manner that a portion of the linkage assembly moves through an elliptical path, and a seat mounted on that portion. A foot platform is preferably provided to support a person's feet, and handlebars are preferably provided to support a person's hands. The handlebars may be movably mounted on the frame, and may also be connected to the linkage assembly for synchronized movement with the seat.
Claims23
An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
- a crank rotatably mounted on the frame;
- a seat;
- and
- a seat supporting linkage assembly connected to the seat and movably interconnected between the crank and the frame in a manner that links rotation of the crank to movement of the seat through an elliptical path.
An exercise apparatus, comprising:
- a frame designed to rest upon a floor surface;
- a crank rotatably mounted on the frame;
- a seat;
- and
- an interconnecting means for movably interconnecting the seat between the crank and the frame in a manner that links rotation of the crank to elliptical movement of the seat.
An elliptical motion rowing machine, comprising:
- a frame;
- a linkage assembly movably mounted on the frame in such a manner that a portion of the linkage assently moves through an elliptical path;
- and
- a seat mounted on the portion, thereby defining at least one point of overlap that moves through an elliptical path.
On an exercise rowing machine of a type having a seat movably mounted on a frame, the improvement comprising an elliptical motion linkage assembly interconnected between the seat and the frame in a manner that guides at least a portion of the seat through an elliptical path of motion.
An elliptical motion rowing machine, consisting essentially of:
- a frame;
- a crank rotatably mounted on the frame;
- a rocker link pivotally mounted on the frame;
- a connecting link movably interconnected between the rocker link and the crank in such a manner that a portion of the connecting link moves through an elliptical path;
- a seat mounted on said portion thereby defining at least one point of interconnection that moves through an elliptical path;
- and
- a foot platform mounted on the frame forward of the seat.
