Abstract: An exercise device for performing a variety of movement patterns. The exercise device has a pair of linkages, each including an upper link pivotally mounted to a frame and a lower link pivotally coupled to an upper link. A foot support is provided on a distal end of each lower link. A compression link interconnects the lower link to the frame. The compression link includes a shaft coupled to the lower link, a sleeve coupled to the frame and a spring captured between the shaft and the sleeve, whereby the spring provides a resistance to movement of the lower link relative to the frame.

Abstract: An exercise device upon which a user generally standing upright supported by foot platforms suspended from a frame via linkages in which the linkage lengths and pivot points correspond generally to the users upper and lower legs and hip and knee joints. This device not only allows natural free and spontaneous leg movement, able to simulate such exercises as walking, jogging, running, stepping, skiing or gliding, bicycling, climbing, reverse action and various isolated leg exercises, where the exercises can be performed at random generally without the need to reconfigure the device. This device preferably includes an isolation system capable of simulating natural forces throughout the entire range of movement in the horizontal and/or vertical plane. A safety/suspension system can be provided, alone or in combination with the isolation system, to resist sudden foot movement in the same direction, yet allows a slow and controlled tilting of the linkages whereby the user may simulate uphill and downhill travel.

Abstract: An exercise device for use by a user, said exercise device comprising a frame, first and second linkages pivotally carried by a frame, each of the linkages including an upper link and a lower link; each of the upper links being pivotally connected to the frame, each of the lower links being pivotally connected to the upper link; first and second foot supports, the first foot support carried by the lower link of the first linkage and the second foot support carried by the lower link of the second linkage; and means for coupling the movement of the first foot support and the second foot support whereby the user of the exercise device may perform a walking, striding, or stepping exercise without reconfiguring the exercise device.

Abstract: A displaceable seat exercise system (10) is provided wherein a user's legs and arms may be independently exercised. A seat assembly (40) is rotatively coupled to a base frame (12) by means of a parallelogram linkage assembly (90). The user displaces seat assembly (40) by extending his or her legs against a stationary foot support assembly (80), the foot support assembly being affixed to the base frame (12). Seat assembly (40) carries an arm member support assembly (50) which includes a pair of rotary resistance assemblies (120, 130) and respective rotatively coupled arm members (64, 62) for rotation by each of the user's arms, respectively. Seat assembly (40) may be collapsed into juxtaposition over base frame (40) and partially overlaid by the foot platform (88) to releasably secure exercise system (10) in a compact storage configuration.

Abstract: An aerobic exercise device provides for a smooth, natural, orbital continuous motion of the user's feet. This device can be used for walking, running, jogging or stair-stepping exercises. Upper body workout devices can be provided with the aerobic exercise device such that a total body workout can be had. The device includes two parallel tracks with platforms. The platforms reciprocate along the tracks. A device is provided in each track for returning the platforms to the home position. As a user operates the device, he or she will push the platforms rearwardly. When the user's foot reaches the end of his or her stride, the user can then lift their foot in a natural motion. The device will return the platform to the home position. As the platform is returning to the home position, it will first travel in a forward direction and then switch to a rearward direction. This rearward movement will enable comfortable planting of the user's foot as it reengages the platform.

Abstract: A home gym system (100) is provided for performing weight lifting exercises with a load resistance (160, 164) coupled to a cable (132). The home gym system (100) includes a main frame (110) to which is pivotedly coupled at least one extension frame (120). A guide arm assembly (130) is slidingly coupled to frame extension (120) and vertically displaceable thereon. Vertical displacement of guide arm assembly (130) is made substantially effortless by a counter weight system (140) coupled to guide arm assembly (130) by a flexible member (141). Counter weight system (140) includes a floating pulley system (145) to compensate for changes in cable path length which result from the vertical displacement of guide arm assembly (130). Additionally, guide arm assembly (130) includes a system for increasing the load resistance by varying the mechanical advantage of the cable system.
