This application claims priority of U.S. Provisional Patent Application No. 61/453,751 filed Mar. 17, 2011, entitled “Adaptive Exercise Device with Independent Motion”, the contents of which are incorporated herein by reference.
FIELD OF THE INVENTIONThis invention relates to exercise devices, and more particularly to exercise devices which simulate a running and stepping motion. In particular, the invention relates to an adaptive exercise device configured and operable to mechanically decouple the vertical and horizontal components of the foot and leg motion so as to allow a user to independently control them during the use of the device.
BACKGROUND OF THE INVENTIONThere are a variety of exercise devices which attempt to simulate a running and stepping motion in which a user's feet and legs travel along a path having vertical and horizontal components of motion. One group of such devices is termed “adaptive exercise devices”, and they allow a user to vary the degree of foot and leg motion while the device is in use. This invention is directed to a particular type of adaptive exercise device which decouples the vertical and horizontal components of motion so that the horizontal component of foot and leg motion is independent of the vertical component of the motion of the foot and leg.
As will be explained hereinbelow, the present invention allows a user to implement a solely vertical foot and leg motion or a solely horizontal foot and leg motion, or a foot and leg motion which is a blended ratio of the two components. The system of the present invention is of simple mechanical construction, and hence is reliable, easy to maintain, and low in cost. These and other advantages will be apparent from the drawings, discussion, and description which follow.
BRIEF DESCRIPTION OF THE INVENTIONDisclosed is an adaptive exercise device which includes a frame which is configured to be supported on a floor, a primary guide assembly, and a second guide assembly. The device further includes a first and second foot link, each foot link having a foot pad portion configured to receive a user's foot. Each foot link is disposed so as to engage the primary guide assembly which in turn is configured and operable to direct the foot pad portions of the foot links along a first path of travel having a horizontal component of motion. The foot links are further disposed so as to engage the secondary guide assembly which is configured and operable to direct the foot pad portions of each of said foot links along a second path of travel having a vertical component of motion. The device is configured so that the motion of the foot pads along the first path of travel is mechanically independent of the motion of the foot pads along the second path of travel. In one embodiment of the invention, the primary guide assembly includes at least one primary track which is configured and operable to engage and direct the first and second foot links along the first path of travel. The at least one primary track may be inclined relative to a horizontal support surface upon which the device is resting, and the degree of inclination may be made to be adjustable.
In other embodiments, the primary guide assembly includes a first and a second swing arm which are pivotally supported by the frame. Each swing arm is engaged in mechanical communication with a respective one of the foot links so as to at least partially support its respective foot links as it moves along the first path of travel. The swing arms in this embodiment may be pivotally coupled to their respective foot links at a connection point; and when the foot links move along the first path of travel, the connection points define an arc. In this embodiment, the secondary guide assembly may include a first and a second secondary guide track which engage respective foot links; and the secondary track may be curved so that the curvature of those secondary tracks corresponds geometrically to the curvature of the arc defined by the connection points between the swing arms and their respective foot links.
The secondary guide assembly may, in some embodiments, include a first and second track disposed in a parallel relationship with one another, together with a control system which is operative to move said first and second tracks along respective paths of travel having equal and opposite vertical components of motion while maintaining the secondary tracks in a parallel relationship. In this embodiment, the foot links in turn engage respective ones of said first and second secondary tracks so as to be displaceable along the length thereof so that when the secondary control system moves the secondary tracks along their respective paths of travel having the vertical component of motion, that vertical component of motion is communicated to a respective foot link so as to move the foot pad portion of that foot link along a second path of travel having the vertical component of motion.
In yet other embodiments, the secondary guide assembly may include a first and second swing arm, each being coupled to a respective one of the foot links. The secondary guide assembly will, in such embodiments, further include a control system which is operative to move the first and second swing arms along respective paths of travel having equal and opposite vertical components of motion so that when the secondary control system moves the swing arms along their respective paths of travel having the vertical component of motion, that vertical component of motion is communicated to a respective foot link so as to move the foot pad portion along a second path of travel. In some of such embodiments, the swing arms of the secondary guide assembly are each pivotally coupled to their respective foot links at a connection point whereby when the foot links move along the first path of travel, the connection point defines an arc. In these embodiments, the primary guide assembly includes at least one curved guide track which engages the foot links. This at least one track is curved so that the curvature thereof corresponds geometrically to the curvature of the arc defined by the connection points.
Also disclosed herein is a method of exercise comprising the use of the device of the present invention.
The present invention may be implemented in a number of different configurations and will be explained with regard to some specific embodiments. It is to be understood that other modifications and variations are within the scope of this invention and will be readily apparent to those of skill in the art in view of the teaching of this disclosure.
The device 10 of
The device 10 includes a secondary guide assembly 16 which in this embodiment includes a pair of secondary tracks 18a and 18b which are disposed in a parallel relationship and are pivotally supported on the frame 12. The secondary track assembly 16 also includes a secondary track control system 20 which operates to move the first and second secondary tracks 18a, 18b along respective paths of travel having equal and opposite vertical components of motion while maintaining them in a parallel relationship.

In this embodiment, the foot link 30 also includes a first roller 34 and a second roller 36. The first roller 34 engages a bottom surface of the secondary track 18, while the second roller 36 engages a top surface of the primary track 14. Other track and roller configurations may be implemented. As will be appreciated from the figure, the two rollers 34 and 36 cooperate with the tracks 14 and 18 and the frame (not shown) to support the foot link 32 so that when a user's foot is placed on the foot pad 32, the foot link will be stable. As will be seen, the track and roller arrangement allows for the foot link to move back and forth along a reciprocating path of travel having a primarily horizontal component of motion, as shown by arrow B. It will be appreciated from
In keeping with a further feature of the present invention, the fore and aft, generally horizontal, motion of the foot links 30 may be synchronized by a foot link control system which causes the foot links to move in equal and opposite directions along the primary track assembly 14. This may be accomplished through various mechanical arrangements as is known in the art. As is specifically shown in

In the embodiment of
In all of the embodiments of the present invention, vertical and horizontal components of foot motion are mechanically decoupled, and
The fact that the vertical and horizontal components of foot motion are mechanically decoupled also allows for a user to make changes to the foot path while the device is in use. For example, in a typical exercise regimen, a user may initially elect to employ a strictly vertical, up and down foot motion akin to that achieved by the use of a stair stepper device. Subsequently the user may add a horizontal component of motion so as to elongate the stride, eventually achieving an elliptical path. The user may then decrease the vertical component so as to implement a strictly horizontal motion akin to that achieved through a cross country skiing simulator.
The present invention may be implemented in a number of other embodiments which will be apparent to those of skill in the art in view of the teaching presented herein. The foregoing drawings, discussion, and description are illustrative of specific embodiments of the invention but are not meant to be limitations upon the practice thereof. It is the following claims, including all equivalents, which define the scope of the invention.
