Abstract: An exercise device employing side-by-side pivotally supported moving surfaces. In one example, an exercise device employs a first pivotable treadle assembly including a first moving surface, a first foot platform extending outwardly from a side of the first treadle assembly, and a second pivotable treadle assembly including a second moving surface. In some implementations, the exercise device includes a resistance element operably coupled to at least one of the first treadle assembly or the second treadle assembly to resist movement of the at least one of the first treadle assembly or the second treadle assembly. In some implementations, the exercise device includes an adjustment mechanism for adjusting a slope of at least one of the first treadle assembly or the second treadle assembly.

Abstract: An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.

Abstract: Air bed assembly having a knockdown foundation made up of preassembled boxes which are used as shipping containers for the other elements of the bed, mattresses having interposed sets of isolated chambers for improved pressure distribution, contoured foam rails surrounding the mattresses and a visco-elastic foam pad overlying them, a cover with a removable pillow top enclosing the mattresses and foam, a blower assembly mounted inside one of the rails with control valves for supplying air to and removing air from the mattresses, and individual controls for returning the pressure in the mattresses to a desired level upon command and for preventing a drop in mattress pressure as the blower is turned on to increase that pressure.

Abstract: Exercise machine having a frame with a pair of upstanding sections disposed substantially at right angles to each other, a weight stack mounted on each of the frame sections, a cable coupled to each of the weight stacks for transferring a pull on the cable to the weights in the stack, a pulley block through which the cable is pulled, a leg connected to each of the frame sections for movement between a supporting position and a storage position, interlock means engagable between the legs and respective ones of the weight stacks for preventing the weights from being raised when the legs are in the storage position, a bench which is removably connected to the frame and can be folded up between the two frame sections for storage, a carriage mounted on each of the frame sections and adapted to be positioned at different heights, and means mounting one of the pulley blocks on each of the carriages such that each of the pulley blocks is free to pivot about two axes of rotation so that the pulley block can follow the

Abstract: Exercise machine having a base comprising a horizontally extending platform and an upstanding post. A swing arm comprising has a pair of arms and a crossbar is pivotally mounted on the post for movement about a horizontally extending axis, with the crossbar extending in a direction generally parallel to the axis. A first pair of pulleys are mounted on the base in alignment with the horizontally extending axis, and a second pair of pulleys are mounted on the crossbar. A pair of cables are trained about the pulleys, grips are connected to the cables near the second pulleys, and resistance elements are connected to the cables for yieldably resisting movement of the cables when a pull is exerted thereon. A pair of telescoping arms extend between the base and the crossbar for holding the crossbar and the grips at different heights above the platform.
