Abstract:
1. A massage device comprising: a base cover having a rack formed therein; a guiding device comprising a plurality of guiding rails formed in a middle region of the base cover and paralleled to the rack; and a moving base movably engaged with the plurality of the guiding rails of the guiding device, comprising a bottom, a shield positioned over the bottom to form a compartment therebetween, a massage system rotatably placed on the shield, a first transmission system adapted for moving the moving base along the plurality of the guiding rails of the guiding device and a second transmission system adapted for driving the massage system to provide massage effects, both the first and second transmission systems being contained in the compartment and being driven individually, wherein the massage system comprises a pair of rotation shelves each defining a middle shaft bore therein and a plurality of kneading heads rotatably mounted on the pair of rotation shelves; the first transmission system comprises a first motor, a first worm mechanically connected with the first motor, a first worm wheel meshing with the first worm, a small gear coaxially mounted under the first worm wheel, a big gear, an intermediary gear directly meshing with both the small gear and the big gear, and a driving gear coaxially mounted under the big gear and meshing with the rack of the base cover such that when the first motor is activated, it drives the first worm to rotate, the rotation of the first worm results in, in turn, the rotation of the small gear, the intermediary gear, the big gear and the driving gear, thereby moving the moving base along the plurality of the guiding rails of the guiding device, wherein the movement of the moving base causes the plurality of kneading heads of the massage system to translate along the plurality of the guiding rails of the guiding device; and the second transmission system comprises a second motor, a second worm mechanically connected with the second motor, a pair of second worm wheels mechanically and directly meshing with the second worm and a pair of worm wheel shafts each having a first end portion coaxially connected with a respective second worm wheel of the pair of second worm wheels and an opposite, second end portion extending through the shield of the moving base and secured into the middle shaft bore of a respective rotation shelf of the pair of rotation shelves of the massage system, such that when the second motor is activated, it drives the second worm to rotate, the rotation of the second worm results in the rotation of the pair of second worm wheels in opposite directions simultaneously and cooperatively, which in turn, results in the rotation of the pair of worm wheel shafts in the opposite directions simultaneously and cooperatively, thereby simultaneously and cooperatively rotating the pair of rotation shelves in the opposite directions with the plurality of kneading heads to provide kneading and/or massage effects on the left side and the right side of a user's back simultaneously and cooperatively, wherein the moving base further comprises at least one power supply mounted between the bottom and the shield for selectively activating the first and second motors individually or cooperatively, whereby the translation and rotation of the plurality of kneading heads selectively occurs independently or simultaneously.
