Exercise step with adjustable leg bellows

摘要

An exercise step includes a generally rectangular stepping platform having first and second ends and further includes first and second pairs of leg bellows respectively mounted to the first and second ends of the platform thereby forming four legs for supporting the stepping platform above a supporting surface. Each pair of leg bellows is controlled by a single valve for selectively simultaneously inflating or deflating the pair of leg bellows to selectively adjust the height of the platform above a supporting surface. A channel extends between the paired leg bellows at each end of the platform. Each leg bellows includes a flexible air tube extending therefrom, and the air tubes are received in the channels in the bottom of the platform. The valves comprise slotted valve stems which extend into the channels. The paired set of air tubes is received through the slot in the valve stem and the valve stems are slidably movable to open and close paired sets of air tubes in the respective channel to simultaneously control inflation and deflation of each pair of leg bellows.
