Abstract
Abstract An improved body massaging device which is particularly suited to massaging the back and spinal area is disclosed. The device comprises a body supporting surface having an axially reciprocable carriage means positioned generally thereabove. A massaging assembly is attached to and extends downwardly from the carriage means. The massaging assembly includes at least one body contacting means operative to exert pressure upon a human body positioned on the body supporting surface while undergoing axial reciprocation along the length of the subject's spine. The body supporting surface may comprise a standard examining table or any other horizontal surface upon which a human being may lie in a generally prone position. The body contacting means of the massaging assembly may comprise two separate rotatable massage wheels positioned such that one wheel will contact the body on each lateral side of the subject's spine while the subject lies in a prone position on the body supporting surface. The device may include a means for continually or incrementally altering the spacing between such massage wheels during the course of a treatment session. Also, the device may include a separate means for continually or incrementally increasing/decreasing the downward pressure applied by the massaging assembly on the body. High pressure limit switches may be provided to prevent over pressurization of the subject's body.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
A device for massaging an anatomical portion of the body, said device comprising: a body supporting surface; an axially reciprocable carriage means positioned generally above said body supporting surface and operative to reciprocate axially relative thereto; a massaging assembly attached to and extending downwardly from said carriage means, said massaging assembly including at least one body contacting means operative to exert pressure upon a body portion positioned upon said body supporting surface while reciprocating axially in conjunction with said carriage means; at least one pressure sensing limit switch operatively associated with the body contacting means, said body contacting means being downwardly biased at a desired maximum pressure limit such that when said maximum pressure limit is exceeded by the device, the downward biasing of the body contacting means will be overcome so as to thereby result in closure of said at least one pressure sensing limit switch.
Claim 2
Independent Claim
147 words
A device for massaging an anatomical portion of the body, said device comprising: a body supporting surface; an axially reciprocable carriage means positioned generally above said body supporting surface and operative to reciprocate axially relative thereto; a massaging assembly attached to and extending downwardly from said carriage means, said massaging assembly including at least one body contacting means operative to exert pressure upon a body portion positioned upon said body supporting surface while reciprocating axially in conjunction with said carriage means; at least one pressure sensing limit switch operatively associated with the body contacting means, said body contacting means being downwardly biased at a desired maximum pressure limit such that when said maximum pressure limit is exceeded by the device, the downward biasing of the body contacting means will be overcome so as to thereby result in closure of said at least one pressure sensing limit switch.
Claim 3
Independent Claim
126 words
A device for massaging an anatomical portion of the body, said device comprising: a body supporting surface having a longitudinal axis extending therethrough; a carriage means positioned generally above said body supporting surface and operative to reciprocate back and forth in generally parallel relation to said longitudinal axis; and a massaging assembly attached to and extending downwardly from said carriage means, said massaging assembly comprising first and second pivotal connecting members having first and second body contacting means mounted respectively thereon; said first and second pivotal connecting members being operative to pivotally hold said first and second body contacting means in side-by-side juxtaposition such that pivotal movement of said connecting members will result in alteration of the distance between said first and second body contacting means.
Claim 4
Independent Claim
126 words
A device for massaging an anatomical portion of the body, said device comprising: a body supporting surface having a longitudinal axis extending therethrough; a carriage means positioned generally above said body supporting surface and operative to reciprocate back and forth in generally parallel relation to said longitudinal axis; and a massaging assembly attached to and extending downwardly from said carriage means, said massaging assembly comprising first and second pivotal connecting members having first and second body contacting means mounted respectively thereon; said first and second pivotal connecting members being operative to pivotally hold said first and second body contacting means in side-by-side juxtaposition such that pivotal movement of said connecting members will result in alteration of the distance between said first and second body contacting means.
Claim 5
Dependent Claim
72 words
The device of claim 2 wherein said body supporting surface comprises a treatment table having a horizontal upper surface upon which a human being may lie in a generally prone position such that the first body contacting means will contact the back of the body to the left of the spinal column and the second body contacting means will contact the back of the body to the right of the spinal column.
Claim 6
Dependent Claim
38 words
The device of claim 3 wherein said first and second body contacting means comprise first and second massage wheels respectively which roll along either side of the spine in conjunction with the axial reciprocation of said carriage means.
Claim 7
Dependent Claim
37 words
The device of claim 4 wherein said first and second body contacting means may be alternately moved further apart and closer together in conjunction with pivotal movement of the pivotal connecting members as the massaging treatment continues.
Claim 8
Dependent Claim
38 words
The device of claim 5 further comprising means for causing the pivotal positioning of the pivotal connecting members and the resultant distance between said body contacting means to change by predetermined increments while said axially reciprocating motion continues.
Claim 9
Dependent Claim
35 words
The device of claim 5 further comprising a means for causing the pivotal positioning of the pivotal connecting members and the resultant distance between said body contacting means continuously while said axially reciprocating motion continues.
Claim 10
Dependent Claim
64 words
The device of claim 2 wherein said carriage means comprises: an overhead housing; at least one slide rail positioned longitudinally within said overhead housing; a slidable mounting block disposed on said longitudinal slide rail so as to be reciprocably moveable therealong; a propulsion means operatively connected to said mounting block to reciprocally drive said mounting block back and forth along said longitudinal slide rail.
Claim 11
Dependent Claim
25 words
The device of claim 1 further comprising means for adjusting the pressure exerted by the first and second body contacting means upon the body portion.
Claim 12
Dependent Claim
45 words
The device of claim 9 wherein said means for adjusting the pressure exerted by the first and second body contacting means upon the portion of the body is operative to periodically increase said pressure by predetermined periodic increments while said axially reciprocating massage motion continues.
Claim 13
