Abstract
Abstract A gravity lumbar reduction maintenance apparatus of multiple use consisting of a rectangular frame capable of being mounted upon a tubular base in a variety of positions and orientations to the vertical. A web extending over the frame permits a patient to rest upon the web, and the frame may be oriented in a vertical manner having a harness affixed thereto providing support during therapy. The apparatus is characterized by its versatility and multiple modes of assembly permitting a wide variety of therapeutic treatment.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
Gravity lumbar reduction maintenance apparatus capable of being oriented to the vertical in a plurality of positions compsiring, in combination, a tubular base formed in a planar rectangular configuration having parallel sides and parallel ends, a tubular body frame formed in a planar rectangular configuration having parallel sides and parallel first and second ends, said body frame first end defined by an upper tubular cross piece and said body frame second end defined by a lower tubular cross piece, said body frame parallel sides each extending beyond said second end cross piece terminating in a free end, a yoke mounted upon each free end having spaced legs having aligned holes therein for receiving a pin, a plurality of first spaced connection means defined in said base sides, second connection means defined on said frame sides, a body supporting web affixed to said frame extending between said sides thereof, and at least a pair of primary links each having ends having connection means defined thereon associated with said base and said frame connection means to maintain a preselected angular relationship between said base and frame, the connection means on one end of a link cooperating with said first connection means on said base and the connection means on the other end of a link cooperating with said second connection means on said frame, said yokes being selectively connectable to said second connection means.
Claim 2
Dependent Claim

Gravity lumbar reduction maintenance apparatus capable of being oriented to the vertical in a plurality of positions compsiring, in combination, a tubular base formed in a planar rectangular configuration having parallel sides and parallel ends, a tubular body frame formed in a planar rectangular configuration having parallel sides and parallel first and second ends, said body frame first end defined by an upper tubular cross piece and said body frame second end defined by a lower tubular cross piece, said body frame parallel sides each extending beyond said second end cross piece terminating in a free end, a yoke mounted upon each free end having spaced legs having aligned holes therein for receiving a pin, a plurality of first spaced connection means defined in said base sides, second connection means defined on said frame sides, a body supporting web affixed to said frame extending between said sides thereof, and at least a pair of primary links each having ends having connection means defined thereon associated with said base and said frame connection means to maintain a preselected angular relationship between said base and frame, the connection means on one end of a link cooperating with said first connection means on said base and the connection means on the other end of a link cooperating with said second connection means on said frame, said yokes being selectively connectable to said second connection means.
Claim 3
Dependent Claim
20 words
In a gravity lumbar reduction maintenance apparatus as in claim 1, foot rests defined on said frame lower cross piece.
Claim 4
Dependent Claim
31 words
In a gravity lumbar reduction maintenance apparatus as in claim 1, wherein said first and second connection means comprise spaced holes defined in said sides of said base and frame, respectively.
Claim 5
Dependent Claim
39 words
In a gravity lumbar reduction maintenance apparatus as in claim 1, a hanger socket defined upon said frame adjacent said first end thereof, a hanger adapted to be received within said socket, said hanger including patient weight bearing means.
Claim 6
Dependent Claim
64 words
In a gravity lumbar reduction maintenance apparatus as in claim 1, a pair of secondary links each having ends having connection means defined thereon, said primary links including secondary link connection means intermediate their ends whereby said secondary links may be connected at one end to said primary links intermediate said primary links' ends and at the other end to said base connection means.
Claim 7
Dependent Claim
70 words
