Abstract
Abstract A massage-exerciser device consisting of a number of resilient discs of frustoconical shape assembled in stacked coaxial relation to form a roller having peripheral ribs and grooves, said discs being reversible whereby to vary the pattern of said ribs and grooves, hard and soft spacers adapted to be inserted selectively between said discs whereby to increase or decrease the effective hardness of the roller, and a clamp for applying a variable axial compressive load to said roller, also to vary the effective hardness thereof, and a frame for carrying a plurality of said rollers rotatably in parallel, spaced-apart relation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
105 words
A massage-exerciser device comprising: a. a series of flat circular discs of resilient material of nonuniform diameter from end to end whereby to present peripheral ribs and grooves, the rib and groove of each of said discs being asymmetrical with respect to the ends of said disc, and b. means assembling said discs in stacked, coaxial relation to constitute conjointly a roller having peripheral ribs and grooves, and said assembly means being operable to permit selective end-for-end reversal of any of said discs, whereby, in conjunction with the asymmetrical configuration of each of said discs, to vary the rib and groove pattern of said roller.
Claim 2
Dependent Claim
105 words
A massage-exerciser device comprising: a. a series of flat circular discs of resilient material of nonuniform diameter from end to end whereby to present peripheral ribs and grooves, the rib and groove of each of said discs being asymmetrical with respect to the ends of said disc, and b. means assembling said discs in stacked, coaxial relation to constitute conjointly a roller having peripheral ribs and grooves, and said assembly means being operable to permit selective end-for-end reversal of any of said discs, whereby, in conjunction with the asymmetrical configuration of each of said discs, to vary the rib and groove pattern of said roller.
Claim 3
Dependent Claim
89 words
A device as recited in claim 1 wherein each of said discs is of larger diameter at one end than at the other end, whereby if the discs are assembled with the larger ends of adjacent discs in abutment, said larger ends conjointly form a single rib of relatively blunt, obtuse cross-sectional contour, and whereby if the discs are assembled with the larger end of one disc abutting the smaller end of an adjacent disc, said larger end forms a single rib of relatively sharp or acute cross-sectional contour.
Claim 4
Dependent Claim
32 words
A device as recited in claim 1 wherein the peripheral surface of each of said discs is of generally frustoconical form, being of larger diameter at one end than at the other.
Claim 5
Dependent Claim
32 words
A device as recited in claim 1 with the addition of means operable to apply a variable compressive load to said stack of discs in a direction parallel to their common axis.
Claim 6
Dependent Claim
33 words
A device as recited in claim 1 wherein said assembling means includes means operable to apply a variable compressive load to said stack of discs in a direction parallel to their common axis.
Claim 7
Dependent Claim
72 words
A device as recited in claim 1 wherein said assembling means comprises a rigid mandrel extending axially through each of said discs and having an enlargement thereon at the respectively opposite ends of said stack of discs, said enlargements abutting the endmost discs of said stack of discs and one of said enlargements being adjustably movable along said mandrel, whereby to apply a variable axial compressive load to said stack of discs.
Claim 8
Dependent Claim
43 words
A device as recited in claim 1 with the addition of one or more spacer members interposed between successive pairs of said discs, and being formed of a resilient material softer and more yieldable than the material of which said discs are formed.
Claim 9
Dependent Claim
31 words
A device as recited in claim 1 with the addition of one or more spacer members interposed between successive pairs of said discs, and being formed of a substantially rigid material.
Claim 10
Dependent Claim
50 words
A device as recited in claim 1 including a plurality of said rollers having their axes disposed in parallel, spaced-apart, coextensive coplanar relation, and with the addition of a frame retaining said rollers in this relation, and in which each of said rollers is mounted for rotation about its axis.
