Abstract
Abstract A lightweight portable massaging platform in which a plurality of free rolling rollers are mounted in a carriage which reciprocates along a stationary track. The rollers are journaled in bearings which serve to accommodate both the free turning of the rollers and the reciprocal motion of the carriage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
In a lightweight, portable massaging platform: a rectangular frame member including track members extending longitudinally of said frame member, a moveable carriage member, a plurality of free rotating roller elements retained in transverse parallel arrangement by said carriage member and moveable therewith, means for reciprocating said carriage member in said frame member, the remote ends of said roller elements being journaled in self-contained bearings, said bearings being movably supported on said track members independently of the rotation of said roller elements, said carriage member being supported by said bearings for reciprocal motion in said frame member along said track members whereby said carriage member moves independently of the rotation of said roller elements.
Claim 2
Dependent Claim
113 words
In a lightweight, portable massaging platform: a rectangular frame member including track members extending longitudinally of said frame member, a moveable carriage member, a plurality of free rotating roller elements retained in transverse parallel arrangement by said carriage member and moveable therewith, means for reciprocating said carriage member in said frame member, the remote ends of said roller elements being journaled in self-contained bearings, said bearings being movably supported on said track members independently of the rotation of said roller elements, said carriage member being supported by said bearings for reciprocal motion in said frame member along said track members whereby said carriage member moves independently of the rotation of said roller elements.
Claim 3
Dependent Claim
19 words
In a lightweight, portable massaging platform of claim 1 means for controlling the rate at which carriage member reciprocates.
Claim 4
Dependent Claim
29 words
A lightweight, portable massaging platform of claim 1 wherein the means for reciprocating includes a timing member which inactivates said means for reciprocating after a predetermined period of operation.
Claim 5
Dependent Claim
15 words
A lightweight, portable massaging platform of claim 1 including a flexible covering over said rollers.
Claim 6
Dependent Claim
16 words
A lightweight, portable massaging platform of claim 1 including a headrest mounted on said frame member.
Claim 7
Dependent Claim
109 words
In a lightweight, portable massaging platform, a reciprocating roller carriage, a plurality of free rotating roller elements retained in a predetermined spaced relationship by said carriage, said roller elements being journaled in self-contained bearings, each of said bearings having an inner race and an outer race, said roller elements being mounted in said inner races, said outer races being supported for rolling movement on a stationary track means, and means for imparting reciprocal motion to said carriage, said carriage being supported by said roller elements whereby said bearings support both the carriage and the roller elements so that the roller elements rotate independently of the movement of the carriage.
Claim 8
Dependent Claim
109 words
In a lightweight, portable massaging platform, a reciprocating roller carriage, a plurality of free rotating roller elements retained in a predetermined spaced relationship by said carriage, said roller elements being journaled in self-contained bearings, each of said bearings having an inner race and an outer race, said roller elements being mounted in said inner races, said outer races being supported for rolling movement on a stationary track means, and means for imparting reciprocal motion to said carriage, said carriage being supported by said roller elements whereby said bearings support both the carriage and the roller elements so that the roller elements rotate independently of the movement of the carriage.
