Benefits of technology

The invention offers several versions of an elliptical exercise device that have a suitable path of motion and are compact and easy to use. These versions also feature reduced complexity in their mechanics.

Problems solved by technology

Many such elliptical exercise devices are large, complicated, costly, and / or have undesirable characteristics related to the motion of the user's feet.
The device provides a path of travel that simulates running and / or walking but is quite large and does not provide for arm exercise.

first embodiment

[0050]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. The frame 12 may be send to have a forward portion forward of the first pivot axis, which is to the left in the view of FIG. 1, and a rearward portion rearward of the first pivot axis, which is to the right in the view of FIG. 1.

second embodiment

[0068]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 arm 114 to pivot about the pivot location 118, thereby causing the foot support link 128 to move upwardly and downwardly. In this embodiment, the rearward end 126 of the rocker arm 126 ac...

third embodiment

[0069]Referring now to FIGS. 5 and 6, an elliptical exercise device in accordance with the present invention is shown at 150. The exercise device 150 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 first end 162 of the flexible coupling 160 of the device 150 is attached to the first intermediate link 146, rather than being attached to the crank system 134. This is an example of an indirect coupling of the end 162 to the crank system, since the flexible coupling is coupled to the crank system by being connected to the intermediate link 146, which is connected to the crank system. The flexible coupling is coupled to the crank system through the intermediate link. This approach may be beneficial in some versions of the present invention, and provides a similar motion profile to the earlier versions. The approximate path of movement of the first end 162 is shown in da...

Abstract

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