Abstract
Abstract A lower body supporting structure is disclosed for slidable adjustment along the lower end portion of an elongated central frame member of a tiltable body exerciser, the exerciser including an upper body supporting portion secured to the upper end of the central frame member. The lower body supporting structure includes an inverted U-shaped carriage member mounted upon and slidable along a substantially square central frame member. A step or foot rest laterally attached to the lower end of the carriage member is adapted to extend under each foot. A pair of laterally-extending ankle-area embracing members are adjustably attached to the carriage member. A manually releasable locking means, pivotally mounted to the lower end of the carriage member about the axis of the foot rest, includes a locking pin for insertion into and removal from a selected aperture within the central frame member. Release of the locking pin by raising the locking means permits both adjustment of the ankle-area embracing means and movement of the carriage member. A foot instep embracing means attached to a lever arm is adapted for engagement with the carriage member in interlocking fashion with the manually releasable locking means. Insertion of the lower end of the lever arm within the interlocking mechanism secures the lever arm, prevents movement of the locking pin, and secures the ankle-area embracing means. The upper end of the lever arm is releasably attached to the central frame member.
