Abstract
Abstract Apparatus for passively exercising a person''s abdominal muscles including a stationary table and a reciprocating table, upon which the person to be exercised is disposed with a portion of his body on each table. The reciprocating table is then moved upward and downward to effectuate a 90* movement of the person to be exercised, from a prone position to a sitting position. The reciprocating table may be moved by an oscillating mechanism which includes a motor which drives a gear box, turning arms appropriately connected to the reciprocating table to change the rotary output from the gear box to reciprocate the table between the 0* and 90* positions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
An apparatus for passively exercising a person''s abdominal muscles comprising, a frame, first and second tables carried by said frame, said first table being stationary and disposed horizontally, said second table rotatable about an axis along one of its ends near an end of said first table and being movable between substantially horizontal and vertical positions, and means interconnecting said frame and said second table for reciprocating said second table between the substantially horizontal and vertical positions.
Claim 2
Independent Claim
77 words
An apparatus for passively exercising a person''s abdominal muscles comprising, a frame, first and second tables carried by said frame, said first table being stationary and disposed horizontally, said second table rotatable about an axis along one of its ends near an end of said first table and being movable between substantially horizontal and vertical positions, and means interconnecting said frame and said second table for reciprocating said second table between the substantially horizontal and vertical positions.
Claim 3
Dependent Claim
58 words
The apparatus of claim 1 wherein said means for reciprocating said second table comprises, a motor mounted on said frame to provide a rotational torque, means connected to said motor for reducing the speed of its rotational torque and means interconnecting said second table and said converter for reciprocating said second table between the horizontal and vertical positions.
Claim 4
Dependent Claim
102 words
The apparatus of claim 2 wherein said means for reciprocating said second table comprises, an axle carried upon said frame and rotated by said motor, at least two arms, one of the said at least two arms being affixed at one of its ends to said axle and rotated thereby, and being rotatably connected at its other end to one end of another of said at least two arms, and said other of said at least two arms being rotatably connected at its other end to said second table, whereby said second table is reciprocated between the substantially vertical and horizontal positions.
Claim 5
Dependent Claim
30 words
The apparatus of claim 3 further comprising, a dashpot interconnecting said frame and said second table to support said table when it is reciprocated between its vertical and horizontal positions.
Claim 6
Dependent Claim
17 words
The apparatus of claim 3 wherein said converter comprises a gearbox which carries and rotates said axle.
