Abstract: An auxiliary device is used in conjunction with a back massaging device and is composed of a base, a movable seat, a plurality of crank axles, a plurality of roller sets, and a transmission apparatus. The base is provided with a plurality of compression springs to enable the movable seat, the crank axles, and the roller sets to swivel in all directions so as to bring about an effective rubbing of the curved portions of the back of a person. The movable seat is provided with an arcuate slot to prevent the vertebrate of the person from making contact with the movable seat.

Abstract: An improved structure of a pad type roller massager including a limiting frame body and a roller mounting seat. The limiting frame body has a substantially inverted U-shaped cross section and may be mounted on the backrest of a chair. The limiting frame body includes a driven gear and a transmission worm gear disposed at tip and bottom sides thereof, both linked up by a chain. A section of the chain is disposed in a recess at an open front side of the limiting frame body with one section connected to a bottom side of the roller mounting seat so that the latter is brought to displace synchronously with the chain. Limiting bolts fitted with elastic sleeves are provided on both sides of the roller mounting frame and fitted into both side walls of the limiting frame body to be subjected to limitation of the vertical sliding displacement thereof.

Abstract: A pad type roller massager comprising an upper supporting bracket and a lower supporting brackets, an upper bracket cover and a lower bracket cover, a driving mechanism, a guiding column A, a sliding block, an eccentric motor, a positioning cover for motor, a position controller, a plurality of screws S, and a rollers assembly is provided. The upper and lower supporting brackets are connected by those pair of guiding column which are parallel with each other. A sliding block is moveably attached to the guiding columns and may move upward and downward along the guiding columns. The upper supporting bracket is enclosed with an upper bracket cover and the upper supporting bracket is rotationally disposed with a pulley therein. The lower supporting bracket is also enclosed with a lower bracket cover and the lower supporting bracket is disposed with a worm gear motor which in turn meshed with a worm gear having a pulley formed thereof. A belt is guided via the pulley and the worm gear having pulley.

Abstract: A multi-function cleaner provided with three rotating shafts that are connectable with a scrubbing brush, a floor wax polisher and an air extractor vane wheel to permit the cleaner to perform the functions of scrubbing, polishing and dust extraction. The shafts are driven by a motor through a gearing arrangement to rotate the shafts at different speeds. The shaft connectable to the scrubbing brush includes a water outlet which receives water from an inlet forming part of a handle for the cleaner and the air extractor vane wheel is carried by a detachable cover provided with an extended sucker for facilitating the dust suction operation.
