Benefits of technology

[0008] The present invention provides exercise machines for facilitating a foot movement of a user to follow a generally elliptical path. Particular embodiments of the exercise machine include a static disk that is fixed in place and a dynamic disk that both rotates about its axi

Problems solved by technology

However, as opposed to stationary bicycles and stair climbing machines, the pedals of an elliptical pedal exerciser do not traverse a circular path of motion or an oscillating up-and-down path of motion.

Embodiment Construction

[0022] The present invention provides an exercise machine that facilitates the foot movement of a user to follow a generally elliptical path during use of the exercise machine. FIG. 1 describes an ellipse. The ellipse 11 is defined by its major axis 12 and its minor axis 13. Generally, without limiting the invention, it is preferred that elliptical exercise trainers provide a foot movement having a generally elliptical path that has a major axis 12 of between about 16 inches and about 24 inches, more preferably about 20 inches, and a minor axis 13 of between about 2 inches and about 8 inches, more preferably about 4 inches.

[0023]FIG. 2 is a front view of an exemplary drive mechanism for one side of an elliptical trainer in accordance with the present invention and FIG. 3 is a side view of the exemplary drive of FIG. 2. The description of the drive mechanism that follows is of only one pedal driven drive mechanism. However, as known to those having ordinary skill in the art, ellipti...

Abstract

An exercise machine includes a static disk that is fixed in place and a dynamic disk that both rotates about its axis and revolves about the static disk. The static disk and the dynamic disk are mechanically coupled in a manner that provides a constant angular relationship between the rotation of the dynamic disk about its axis and the revolution of that axis about the axis of the static disk. The machine further includes a rotating member supported by a static pivot axis and a crank axle to which the dynamic disk is fixed. The crank axle is rotated by a crank and the rotating member imposes a fixed distance between the crank axle and the static pivot axis. The foot pedal member is pivotally supported at a distal end of the crank so that rotation of the crank causes the foot pedal to follow a generally elliptical path.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates generally to exercise equipment and more particularly, to exercise equipment that facilitates the foot movement of a user through a generally elliptical path. [0003] 2. Description of the Related Art [0004] Exercise equipment has been designed to facilitate a variety of exercise motions. For example, treadmills allow a person to walk or run in place; stepper machines and climber machines allow a person to climb in place; bicycle machines allow a person to pedal in place; and still other machines allow a person to skate and / or stride in place. Yet another type of exercise equipment facilitates relatively more complicated exercise motions and / or better simulates real life activity. Such equipment typically links a relatively simple motion, such as circular motion, to a relatively more complex motion, such as elliptical motion. [0005] Elliptical exercisers permit a user to stand on pedal mechanis...
