Abstract

A rolling massage device for massaging skin areas and reflex zones of the human body includes at least one shaft mounted on a handle and massage rings or rolling bodies which are freely rotatably mounted on the shaft. The massage rings or rolling bodies have prong-like, tooth-like, or needle-like projections which are preferably uniformly distributed in circumferential direction. The massage rings or rolling bodies are spaced apart from each other by means of spacer rings which are also mounted on the shaft. Each massage ring or rolling body is provided with a double row or multiple rows of projections. The rows of projections have a predetermined or fixed lateral spacing between each other. The projections of adjacent rows of projections are arranged staggered relative to each other in circumferential direction.

Claims

1. A massage device for carrying out a rolling massage of skin areas and reflex zones of the human body, the massage device comprising a handle, at least one shaft attached to the handle, a plurality of ring-shaped rolling bodies mounted on the at least one shaft, each rolling body having a plurality of projections uniformly distributed in a circumferential direction thereof, the projections being arranged in two rows, wherein the projections within one row of projections are spaced apart from each other by a division distance, wherein the projections of adjacent rows of projections on each rolling body are arranged staggered relative to each other in the circumferential direction, and wherein the projections of adjacent rows of projections are spaced apart from each other in circumferential direction by a stagger distance, the stagger distance corresponding to approximately half the division distance, wherein each rolling body comprises two disk members attached to each other in a mirror-inverted arrangement, each disk member having one of the rows of projections, the projections being teeth having outer and inner side surfaces, the disk members having outer surfaces and inner surfaces, the disk members being attached to each other at the inner surfaces in a common center plane, the outer side surfaces of the teeth being in alignment with the outer surfaces of the disk members, and the inner side surfaces of the teeth being inclined away from the center plane.

2. The massage device according to claim 1, further comprising spacer rings mounted on the at least one shaft for maintaining a distance between the rolling bodies.

3. The massage device according to claim 1, wherein the projections are one of tooth-like, prong-like and needle-like projections.

4. The massage device according to claim 1, wherein the projections being outwardly conically narrowing teeth, and wherein the teeth have free ends, each free end comprising a convexly arched crest.

5. The massage device according to claim 4, wherein the disk members forming the rolling bodies with the projections arranged in at least two rows are one of diecast or injection molded members of metal or plastics material.

6. The massage device according to claim 4, wherein each rolling body has a plane of rotation, the crest at the free end of each tooth having a radius of approximately 0.25 mm in a direction of the plane of rotation and a radius of approximately 0.15 mm in a plane extending transversely of the plane of rotation.

7. The massage device according to claim 1, wherein the two disk members are attached to each other by one of pressing, welding, riveting and gluing.

8. The massage device according to claim 1, wherein the disk members are of metal or plastics material.

9. The massage device according to claim 1, wherein each disk member has a thickness of 0.8 mm.

10. The massage device according to claim 1, wherein at least the projections of the rolling bodies have a coating of noble metal.

11. The massage device according to claim 10, wherein the noble metal is silver or gold.

12. The massage device according to claim 1, wherein each disk member has a center hole, a first of the two disk members having a unilaterally projecting collar surrounding the center hole thereof, the collar of the first disk member being inserted into the center hole of a second of the disk members, the center hole of the second disk member having an edge, the collar having a rim, the rim of the collar projecting beyond the outer surface of the second disk member, the rim of the collar having a bent portion in contact with the edge of the center hole of the second disk member.

13. The massage device according to claim 12, wherein the edge of the center hole of the second disk member has a chamfered portion, wherein the chamfered portion receives the bent portion of the collar.

14. The massage device according to claim 12, wherein the bent portion of the neck of the first disk member is a pressed member.

15. The massage device according to claim 12, wherein the collar of the first disk member is a deep-drawn member.

16. The massage device according to claim 12, wherein the collar projects from the inner surface of the first disk member.

17. The massage device according to claim 1, wherein each rolling body comprises three disk members, the disk members being flat bevel wheels and each disk member having one of the rows of projections.
