Abstract
Abstract A tilt bed exercise device for rotating a human into inverted posture is provided with a pair of pivot bearings holding a rotatable tilt bed comprising a human torso conforming support with a beam extending therefrom and terminating in a rail canted at an angle wherein the proximal end of the rail is anterior of the user's ankles and the distal end is posterior to the user's ankles. A foot supporting means is slidably attached to the canted rail with selectable fixed locations suitable for different size humans. The user's ankles are held by supporting means including a hook on each ankle support engageable with the foot supporting means. A pivot stop is provided for the tilt bed wherein the foot supporting means is rotated past the vertical plane through the axis of the pivot bearings.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
218 words
An exercise device comprising: (a) a pair of spaced apart pivot bearings; (b) means for supporting said pivot bearings in a coaxial relationship parallel to and spaced above a floor surface; (c) a tilt bed disposed between said pivot bearings and pivotally mounted therein at its approximate midpoint, and an extension means extending longitudinally from the lower end thereof; (d) ankle holding means attached to said extension means for the secure attachment of a user's ankles to said tilt bed; (e) a pivot stop means wherein said tilt bed supporting the user may be rotated to a stop position with said ankle holding means rotated past the vertical plane through the axis of said pivot bearings; (f) adjustment means on said tilt bed which allows said ankle holding means to be selectively longitudinally positioned with respect to said pivot bearings so that said ankle holding means can be positioned over a range of locations relative to said vertical plane when said tilt bed is at said stop position, said range being from a fixed distal position wherein said ankle holding means is closest to said vertical plane through the axis of said pivot bearings to a fixed proximal position wherein said ankle holding means is farthest away from said vertical plane through the axis of said pivot bearings.

An exercise device comprising: (a) a pair of spaced apart pivot bearings; (b) means for supporting said pivot bearings in a coaxial relationship parallel to and spaced above a floor surface; (c) a tilt bed disposed between said pivot bearings and pivotally mounted therein at its approximate midpoint, and an extension means extending longitudinally from the lower end thereof; (d) ankle holding means attached to said extension means for the secure attachment of a user's ankles to said tilt bed; (e) a pivot stop means wherein said tilt bed supporting the user may be rotated to a stop position with said ankle holding means rotated past the vertical plane through the axis of said pivot bearings; (f) adjustment means on said tilt bed which allows said ankle holding means to be selectively longitudinally positioned with respect to said pivot bearings so that said ankle holding means can be positioned over a range of locations relative to said vertical plane when said tilt bed is at said stop position, said range being from a fixed distal position wherein said ankle holding means is closest to said vertical plane through the axis of said pivot bearings to a fixed proximal position wherein said ankle holding means is farthest away from said vertical plane through the axis of said pivot bearings.
Claim 3
Dependent Claim
169 words
An exercise device comprising, a pair of spaced apart pivot bearings, a frame for supporting said pivot bearings in a coaxial relationship parallel to and spaced above a floor surface, said frame having two anterior legs and two posterior legs wherein the anterior legs are spaced closer than the posterior legs, a tilt bed disposed between said pivot bearings and pivotally mounted therein at its approximate midpoint; a beam extending from the lower end of said tilt bed terminating in an elongated rail adapted to be disposed between the ankles of a user; a foot supporting means attached to said rail; and pivot stop bar means extending laterally outwardly from opposite sides of said bed adapted to pass between said posterior legs and to strike said anterior legs of said frame and stop rotation of said tilt bed whereby said tilt bed supporting a user may be rotated to a stop position with said foot supporting means rotated past the vertical plane through the axis of said pivot bearings.
Claim 4
Dependent Claim
