Abstract

A massage device, comprising: a hollow cylindrical outer roller having a first texture formed on an outer surface thereof; and, a cylindrical inner roller having a second texture formed on an outer surface thereof and sized to fit concentrically within the hollow cylindrical outer roller; wherein the cylindrical inner roller is moveable between a first position within the hollow cylindrical outer roller and a second position outside of the hollow cylindrical outer roller.

First claim

What is claimed is:

1 . A massage device, comprising:
a hollow cylindrical outer roller having a first texture formed on an outer surface thereof; and, an inner roller having a second texture formed on an outer surface thereof and sized to fit concentrically within the hollow cylindrical outer roller; wherein the inner roller is moveable between a first position within the hollow cylindrical outer roller and a second position outside of the hollow cylindrical outer roller.

2 . The massage device of claim 1 , wherein the inner roller is a solid cylindrical inner roller.

3 . The massage device of claim 1 , wherein the inner roller is a hollow cylindrical roller.

4 . The massage device of claim 3 , further comprising one or more pouches disposed within the inner roller, the one or more pouches being at least one of microwavable and freezable for temperature control.

5 . The massage device of claim 3 , wherein the inner roller is closed at one end thereof and wherein an inflating port with a closure is formed at an opposite end thereof to inflate or deflate the inner roller by changing a pressure in an inner cavity of the inner roller.

6 . The massage device of claim 1 , further comprising a ball that is removably attached to one end of the inner roller.

7 . The massage device of claim 1 , wherein the inner roller has a bar, a plurality of balls with respective holes formed therethrough stacked on the bar, and a closure removably attached to each end of the bar.

8 . The massage device of claim 1 , wherein the outer roller is made from a first foam material having a first compressibility, and wherein the inner roller is made from a second foam material having a second compressibility.

9 . The massage device of claim 1 , wherein at least one of the outer and inner rollers has a modular configuration having two or more modules attachable one to each other to form the respective outer and inner rollers.

10 . The massage device of claim 1 , wherein respective first and second end surfaces of the inner and outer rollers are flat or approximately flat.

11 . The massage device of claim 1 , wherein the outer roller further comprising a sleeve, the outer roller being insertable into the sleeve.

12 . The massage device of claim 11 , wherein the sleeve has one or more independent parts, each part having a different texture and/or compressibility.

13 . The massage device of claim 1 , wherein the inner roller further comprising a sleeve, the inner roller being insertable into the sleeve.

14 . The massage device of claim 13 , wherein the sleeve has one or more independent parts, each part having a different texture and/or compressibility.

15 . The massage device of claim 1 , further comprising a handle foil led on at least one end of the massage device.

16 . The massage device of claim 15 , wherein the handle is a handle bar extending outwardly from an end surface of the inner roller.

17 . The massage device of claim 1 , further comprising a belt with a respective connector disposed on each end thereof for removably connecting to a respective handle formed on each end of the massage device.

18 . The massage device of claim 1 , wherein the first texture is formed by a plurality of longitudinal grooves.

19 . The massage device of claim 18 , wherein each longitudinal groove extends between first and second ends of the outer roller tracing out a transverse wave-shaped pattern having a first curved crest portion proximate the first end of the outer roller, a flattened trough portion proximate a midpoint of the outer roller, and a second curved crest portion proximate the second end of the outer roller.

20 . The massage device of claim 19 , wherein each longitudinal groove is one of V-shaped or approximately V-shaped in cross-section and sinusoidal or approximately sinusoidal in axial cross-section.

21 . The massage device of claim 1 , wherein the second texture is formed by a plurality of transverse grooves.

22 . The massage device of claim 21 , wherein each transverse groove is an annular groove.

23 . The massage device of claim 22 , wherein each transverse groove is one of V-shaped or approximately V-shaped in cross-section and sinusoidal or approximately sinusoidal in cross-section.

24 . The massage device of claim 3 , wherein the inner roller has an accessible cavity formed therein for storage of one or more massage accessories or balls.
