Back and spine exerciser
First Claim
Patent Images
1. A method of exercising the back and spine of a person, comprising the application to the spine of a gentle, slow cyclical action of alternate periods of tension and relaxation of the tension, by applying a harness to the head and chin of the user, and applying symmetrical and cyclic reciprocating motion of small amplitude having a 360°
- substantially sinusoidal waveform when plotted against time, and of slow period to said harness substantially along a line parallel to the axis of the spine.

4. An apparatus for exercising the back and spine of a person, comprising drive means for generating a substantially linear, symmetrical and reciprocating cyclic motion of small amplitude having a 360°
- substantially sinusoidal waveform when plotted against time, and of slow period, said drive means comprising a rotary shaft, a crank, and a pitman coupled to said crank, a harness means adapted to engage about the chin and head of the person, and means coupling said pitman to said harness means to apply a gentle, slow, symmetrical and cyclical action of alternating periods of tension and relaxation of the tension to the spine of the person.
