## Title
Rotating apparatus for surface massage

## Abstract

A hand held mechanized massager is constructed as a cage with a series of axles arranged in a circular or near circular array. Each of the axles provides a series of side-by side massaging wheels. The wheels have a ridged circumference for rolling on the surface of the skin in a manner for stimulating the muscles and circulatory system. A driver assembly is held in a hand and is actuated for rotation of the cage and wheels.

Polychronis, U.S. Pat. No. 6,306,109, teaches a hand held manual massager constructed as a cylindrical cage with a series of axles arranged in a circular or near circular array. Each of the axles provides a series of side-by-side massaging wheels. The wheels have a ridged circumference for rolling on the surface of the skin in a manner for stimulating the muscles and circulatory system.
The Polychronis patent teaches a manually operated surface massage device that must be pressed against the skin by hand. Such a device suffers from lacking a means for fluidly rolling the device, especially at higher speeds since it is held by its rim in the palm of a hand. There is clearly needed a device such as the prior Polychronis machine but that is able to overcome the problems of rolling and pressing at the same time that the '109 patent fails to teach. The present invention fulfills these needs and provides further related advantages as described in the following summary.
SUMMARY OF THE INVENTION
The present invention teaches certain benefits in construction and use which give rise to the objectives described below.
The present invention provides a hand held mechanized massager constructed as a cylindrical cage with a series of axles arranged in a circular or near circular array. Each of the axles provides a series of side-by-side massaging wheels. The wheels have a ridged or smooth circumference for rolling on the surface of the skin in a manner for stimulating the muscles and circulatory system. The device is approximately the width of a hand and of such size as to be grasped by a hand for manipulation on the body for massage. A battery operated handle is axially mounted and provides continuous rotation.
A primary objective of the present invention is to provide a manual surface massage device having advantages not taught by the prior art.
Another objective is to provide such a massaging device enabled for surface auto-massage.
A further objective is to provide such a massaging device capable of being rolled on separate small wheels or being rotated.
A still further objective is to provide such a massaging device capable of being held in one hand and automatically rotated.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.



BRIEF DESCRIPTION OF THE DRAWING
The accompanying drawings illustrate the present invention. In such drawings:
FIG. 1 is a distal perspective view of a preferred embodiment of the present invention; and
FIG. 2 is a proximal perspective view thereof showing directions of motion.



DETAILED DESCRIPTION OF THE INVENTION
The above described drawing figures illustrate the invention, a mechanized massaging apparatus comprising four essential structural elements. The first of these elements is a plurality of spaced apart frame members, each preferably being a disk 10 or as a circular or oblate (oval) ring as shown in FIGS. 1 and 2. Each of the frame members provides a plurality of axle receiving means such as holes arranged in parallel and in a closed figure such as a circle. The frame members or disks 10 are preferably made of metal or plastic and are rigid elements in the preferred embodiment, but may inventively have some flexibility or resilience.
The second structural element is a plurality of linear axle shafts, i.e., axles 20 all of which preferably have a common diameter and length. All of the axle shafts 20 are positioned in parallel and in circular alignment and are frictionally received by the disks 10 so as to enable the axles 20 and the disks 10 to form a rigid cage structure for fixed frame 40.
The third structural element of the present invention is a plurality of identical disk shaped wheels 30, each of the which provide a peripheral, generally circular and smooth or irregular surface, as is clearly shown in the figures. Each of the wheels 30 provide a central axial hole for receiving one of the linear axle shafts 20 such that each of the wheels 30 is able to freely rotate on the axle shaft 20 it is mounted on, i.e., the central axial hole is large enough for the wheel to freely rotate on its axle shaft 20.
The linear axle shafts 20 are engaged with the disks 10 and the disk shaped wheels 30 to form the fixed frame 40 assembly as is shown in the figures. Each of the wheels 30 on each of the linear axle shafts 20 is separated from each adjacent one of the wheels 30 by one of the disks 10 which therefore establishes a preferred common lateral wheel spacing in the apparatus. This is advantageous during massage since it allows the flesh to move laterally when pressed by a given wheel 30 and this action, as is well known, is highly therapeutic.
The fourth structural element of the present invention is a motorized driver assembly 50 including a stationary handle 60 and, in axial alignment therewith, a revolving portion 70 engaged axially with the disks 10. A driver circuit, including an electric motor 62, power source 64 and switch 66 arranged, as is notoriously well known in the art, for rotating the revolving portion 70 and therefore the fixed frame 40, as is shown in FIG. 2, such that with the stationary handle 60 held in one hand of a user, the revolving portion 70 is driven in rotation for rotating the disks 10, axles 20 and wheels 30.
In use the instant invention is advantageously applied to the surface of the body to produce certain benefits such as relaxing of muscles, improved blood flow, skin toning and other well known benefits which are well defined in the massage practice and literature.
The present invention may be used by simply pressing it into the skin's surface without any motion whatsoever, or by holding the frame 40 so that it cannot rotate and moving it across the skin's surface in a forward and backward oscillating motion, or, finally, as is the preferred embodiment, by driving the frame 40 with the handle 60 so as to rotate about its own axis, thereby bringing rows of the wheels 30 into contact with the shin's surface in a continuous sequential manner.
While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
