Abstract: An exercise apparatus links rotation of a crank to generally elliptical motion of a foot supporting member. A foot supporting linkage is movably connected between a rocker and a crank in such a manner that the foot supporting member moves through paths of motion which are fixed, adjustable or variable.

Abstract: A cabinet door assembly is moveably mounted to a cabinet to selectively close a chamber. The cabinet door has a substantially planar first panel and a substantially planar second panel in a planar parallel configuration. The second panel may retract relative to the first panel upon application of an impact force to the second panel. A stop member may be incorporated to limit the downward movement of the second panel. Ramp surfaces and a guide member cooperate to facilitate upward and/or inward directional movement of the second panel relative to the first panel upon application of an impact force to the second panel.

Abstract: An exercise apparatus includes a frame, a footpad for supporting a user's foot, and a sensor that generates a force indicating signal indicative of a force applied to the footpad in a horizontal direction by the user's foot. A mechanism couples the footpad to the frame and guides the footpad in a closed path having at least first and second mutually perpendicular dimensions in response to forces applied to the footpad by the user's foot, the first dimension being parallel to said horizontal direction. The mechanism resists movement of the footpad in the horizontal direction in response to an electrical control signal supplied as input to the mechanism. A control system receives the force indicating signal and generates the control signal such that the mechanism resists movement depending on the force indicated by the force indicating signal.

Abstract: An exercise apparatus includes a frame for residing on a horizontal surface, a pair of arm-supporting members for supporting the user's arms and a pair of leg-supporting members for supporting the user's legs. A linkage assembly couples the arm-supporting members and leg-supporting members to the frame and moves the arm-supporting members and leg-supporting members in closed paths relative to the frame in response to user forces applied to the arm-supporting members and leg-supporting members. The linkage assembly includes actuators for adjusting dimensions of the closed paths in response to control signal inputs. Sensors mounted on the linkage assembly generate force-indicating signals representing user force. A user interface receives and processes the force-indicating signals and supplies the control signal inputs to the actuators. A dimension of at least one of the closed paths is a function of at least one of the forces applied to the leg and arm-supporting members.

Abstract: An exercise apparatus includes a frame, an arm supporting member, and a leg supporting member. A sensor is connected to at least one of the arm supporting member and the leg supporting member, and/or a resilient member is interconnected between the arm supporting member and either the leg supporting member or the frame. The sensor communicates with a user display and/or a resistance device to indicate the amounts of work performed by the arm supporting member and the leg supporting member, and/or to adjust resistance to movement of the leg supporting member as a function of user force applied against the arm supporting member. The resilient member encourages synchronization of the arm supporting member and the leg supporting member, while allowing some relative movement therebetween.

Abstract: Various exercise machines have foot supporting linkages that move a person's feet through respective left and right paths of motion in respective planes that are skewed relative to one another.

Abstract: An exercise apparatus includes a frame configured to rest on a floor surface; left and right cranks rotatably mounted on the frame; left and right first rocker links pivotally mounted on the frame; left and right drawbar links pivotally interconnected between respective cranks and respective first rocker links; left and right second rocker links pivotally mounted on the frame; and left and right foot links supported by respective cranks and respective rocker links. On one embodiment, the second rocker links are selectively pinned to respective first rocker links to configure the apparatus for elliptical striding exercise, and the second rocker links are alternatively pinned to the frame to configure the apparatus for arcuate stepping exercise. On another embodiment, adjustable length members are interconnected between respective second rocker links and respective first rocker links to accommodate variable elliptical striding motion.

Abstract: An elliptical exercise apparatus includes a frame, a pair of footpads, and a linkage coupling the footpads to the frame and for guiding the footpads in closed paths when a user's feet apply forces to the footpads. The linkage, which includes a rotatable member having an angular position indicative of the positions of the footpads within their closed paths, responds to input control signals by adjusting length and height dimensions of the closed paths. A control system senses the angular position of the rotatable member, senses the forces the user applies to the footpads, and generates the control signals to increase or decrease the path dimensions when it senses particular combinations of angular position and user forces, thereby permitting the user to control the path dimensions by controlling the forces applied to the footpads.
