ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to a means for massaging the back of a person, and more particularly to a device that is fastened with a back massaging chair for enhancing the massaging effect of the back massaging chair.
1. Background of the Invention
The conventional back-massaging devices are generally provided with a plurality of rollers or knobs to bring about the massaging effect. These rollers or knobs are in fact ineffective in rubbing the back of a person, especially the curved portions of the back. In addition, the rubbing of the back by the rollers or knobs of the conventional back-massaging devices often results in a back pain.
2. Summary of the Invention
The primary objective of the present invention is therefore to provide an auxiliary device capable of eliminating the drawbacks of the conventional back-massaging devices described above.
It is another objective of the present invention to provide an auxiliary device capable of enhancing the rubbing effect of a back-massaging means.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by an auxiliary device comprising a base, a movable seat, two or more crank axles, a plurality of massaging rollers, and a transmission apparatus. The base is provided with a plurality of compression springs to enable the movable seat, the crank axles, and the rollers to swivel in all directions, thereby bringing about an effective rubbing of the curved portions of a person's back. The movable seat is provided with an arcuate slot to prevent the person's vertebrae from making contact with device.
The foregoing objectives, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
