first embodiment

[0024]FIG. 1 shows an elliptical exercise device 10 structured in accord with the principles of the present invention. The device includes a frame 12 which is configured and operative to retain and support the various other components of the device on a horizontal surface such as a floor. The frame 12 is typically fabricated from metal and / or composite materials and / or wood, but any material may be used. The frame 12 has an upper portion 14 and a lower portion 16. The lower portion 16 is configured to contact the horizontal surface while the upper portion 14 supports several components of the device 10. A first pivot axis 18 is defined in a central area of the upper portion 14 of the frame 12. A pair of guide links are pivotally interconnected with the frame so as to be pivotable about the first pivot axis 18.

[0025]FIG. 1 is a view of the left side of the exercise device 10 and the left guide link 20 is visible. Because the guide link 20 is shown at the midpoint of its travel, the r...

second embodiment

[0037]Referring now to FIG. 4, an elliptical exercise device in accordance with the present invention is shown at 110. The exercise device 110 shares some components and characteristics with the exercise device 10 in FIG. 1. Only the components that differ will be described. Unlike the device 10 in FIG. 1, the elliptical exercise device 110 includes a mechanical coupling 112 that includes a rocker arm 114 pivotally connected to the frame 116 at pivot location 118. The rocker arm 114 has a forward end 120 that is coupled to the crank system 122 by a flexible element 124. A rearward end 126 of the rocker arm 114 is coupled to the foot support link 128 by a foot support portion 130, taking the form of another flexible element. As the crank system 122 rotates, the flexible element 124 causes the rocker 114 to pivot about the pivot location 118, thereby causing the foot support link 128 to move upwardly and downwardly.

Abstract

An elliptical exercise device includes a frame supporting guide links which provide for horizontal motion of associated foot support links. A mechanical coupling couples the foot support links to the crank system and intermediate links connect the crank system to the guide links such that a foot receiving area of each foot support link moves in an elliptical path when the crank system rotates.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of U.S. Provisional Application 61 / 820,312 filed May 7, 2013, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to elliptical exercise devices in which the path of travel of a user's foot is generally elliptical.BACKGROUND OF THE INVENTION[0003]There are a number of exercise devices which operate to allow a user to implement a foot action which follows a generally closed, curved path of travel, simulating running and / or walking. These devices are generally referred to as “elliptical” exercise devices. Many such elliptical exercise devices are large, complicated, costly, and / or have undesirable characteristics related to the motion of the user's feet.SUMMARY OF THE INVENTION[0004]The present invention offers several embodiments of an elliptical exercise device. Some embodiments offer a path of motion with desirable characteristics. In addition, som...
