Abstract
Abstract This invention is in the general field of Rehabilitation Apparatus for the human back and, in particular, it provides a self-help, portable apparatus, which allows the operator to apply intermittant traction to the lower Lombar region of his back. The position of a radius surface in relation to the position of the operators knees, places the Lombar area of his back on an outside circle that is at the peak of the radius surface. The traction force that is created by the weight of the upper Torso of the operator may be lessened by the use of the operators arms, or it may be increased by pulling on an Adjustable Pull Bar. The apparatus may also be used for strengthening exercises for the back muscles, while the spinal column remains under decompression. The invention is designed for quick assembly, and equally quick "knock down" for storage or transporting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
212 words
A method of self-actuated lombar traction, comprising the steps of: applying and maintaining vertical support to the front of the knees of a patient to provide for the patient to kneel; applying force to the back of the legs adjacent to the legs adjacent to the knees to maintain the knees in said kneeling condition; applying vertical support to the front of the thighs, stomach, and lower chest of a patient to provide for the patient to position the upper chest, shoulders, head, and arms in a start position wherein the patient's back is substantially horizontal; while maintaining said knees in said kneeling condition and while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to use the hands to exert a pulling force to move the upper chest, shoulders, head, and arms in a downward direction so that the patient's back assumes an arcuate shape and the spinal column is caused to be in tension; and while maintaining said knees in said kneeling condition and while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move to return the upper chest, the shoulders, the head, and the arms to said start position.
Claim 2
Independent Claim
212 words
A method of self-actuated lombar traction, comprising the steps of: applying and maintaining vertical support to the front of the knees of a patient to provide for the patient to kneel; applying force to the back of the legs adjacent to the legs adjacent to the knees to maintain the knees in said kneeling condition; applying vertical support to the front of the thighs, stomach, and lower chest of a patient to provide for the patient to position the upper chest, shoulders, head, and arms in a start position wherein the patient's back is substantially horizontal; while maintaining said knees in said kneeling condition and while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to use the hands to exert a pulling force to move the upper chest, shoulders, head, and arms in a downward direction so that the patient's back assumes an arcuate shape and the spinal column is caused to be in tension; and while maintaining said knees in said kneeling condition and while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move to return the upper chest, the shoulders, the head, and the arms to said start position.
Claim 3
Dependent Claim
86 words
Arcuately shaped torso support means for lombar traction apparatus, comprising: a plurality of spaced apart tubes, the respective opposite ends of which have lateral openings; a pair of cables respectively disposed adjacent opposite ends of said tubes and extending through said openings; a plurality of separator beads respectively disposed between adjacent tubes and mounted on said cables and fitting into the lateral openings on adjacent tubes; and means connected with said tubes and with said cables for maintaining the tubes and separator beads in compressive engagement.
Claim 4
Dependent Claim
86 words
Arcuately shaped torso support means for lombar traction apparatus, comprising: a plurality of spaced apart tubes, the respective opposite ends of which have lateral openings; a pair of cables respectively disposed adjacent opposite ends of said tubes and extending through said openings; a plurality of separator beads respectively disposed between adjacent tubes and mounted on said cables and fitting into the lateral openings on adjacent tubes; and means connected with said tubes and with said cables for maintaining the tubes and separator beads in compressive engagement.
Claim 5
Independent Claim
201 words
The method of self-actuated lombar traction, comprising the steps of: applying and maintaining vertical support to the front of the knees of a patient to provide for the patient to kneel; applying vertical support to the front of the thighs, stomach, and lower chest of a patient to provide for the patient to position the upper chest, shoulders, head, and arms in a start position wherein the patient's back is substantially horizontal; while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move the upper chest, shoulders, head, and arms in a downward direction so that the patient's back assumes an arcuate shape and the weight of the head, shoulders, arms, and upper chest causes the spinal column to be in tension; while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move to return the upper chest, the shoulders, the head, and the arms to said start position; and further providing means for the patient to utilize the arms to move, by a pulling force, the head, shoulders, and chest in said downward direction to increase said spinal column tension.
Claim 6
Independent Claim
201 words
The method of self-actuated lombar traction, comprising the steps of: applying and maintaining vertical support to the front of the knees of a patient to provide for the patient to kneel; applying vertical support to the front of the thighs, stomach, and lower chest of a patient to provide for the patient to position the upper chest, shoulders, head, and arms in a start position wherein the patient's back is substantially horizontal; while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move the upper chest, shoulders, head, and arms in a downward direction so that the patient's back assumes an arcuate shape and the weight of the head, shoulders, arms, and upper chest causes the spinal column to be in tension; while maintaining said vertical support to the front of the thighs, stomach, and lower chest, providing for the patient to move to return the upper chest, the shoulders, the head, and the arms to said start position; and further providing means for the patient to utilize the arms to move, by a pulling force, the head, shoulders, and chest in said downward direction to increase said spinal column tension.
