A body-supporting bed pivotally supported on a frame and juxtaposed circular plates controlling pivoting of the bed by a series of locking openings in a first plate, by a locking pin on a second plate, and by an abutment pin on a third plate disposed in arcuate slots in the first and second plates.

A body-supporting bed pivotally supported on a frame and juxtaposed circular plates controlling pivoting of the bed by a series of locking openings in a first plate, by a locking pin on a second plate, and by an abutment pin on a third plate disposed in arcuate slots in the first and second plates. A foot-supporting boom supported to extend an adjustable distance from the foot of the bed and a pair of adjustable spaced padded ankle-securing tubes on the end of the boom and a latch for the tubes including a push rod operated latch piece, the push rod having a knob disposed between the legs of the user.

The improvement in gymnastic equipment including a first equipment-supporting frame to rest on the floor and a second user-supporting frame mounted on said first frame to pivot about a horizontal pivotal axis, said second frame having a body-supporting bed and having foot-engaging means at an end of said bed, said foot-engaging means being operable to support, by the user\s feet, part or all of the user\s weight in various pivotally adjusted normal and inverted positions, comprising: (a) inner, outer and intermediate circular abutting plates centered at said pivotal axis, said outer and intermediate plates having slots oriented on circular arcs in excess of 90°centered on said pivotal axis and registered throughout at least their major extents in one pivotal position thereof, and an outwardly extending abutment pin on said inner plate extending through said slots so that ends of said slots form limits on movement of said abutment pin, (b) said outer plate being secured to said first frame and said inner plate being secured to said second frame to pivot together, and (c) said intermediate plate having a series of locking openings disposed equidistant from said axis and said outer plate having a movable locking pin the same distance from said axis as said locking openings, said locking pin being selectively engageable in said locking openings to limit maximum backward tilting of said bed to substantially complete inversion and to limit forward tilting of said bed to less than the vertical.
