  • Patent number: 5611772
    Abstract: An air massage device which allows for a uniform massage treatment upon a human body. This is accomplished by having a person lie upon an air-mat divided into three distinct sections, with each section corresponding to either the upper, middle or lower region of the human body. Within the upper and middle sections are a plurality of air-bags which can be inflated and deflated independently of each other. In order to massage one of the regions of the human body lying upon the mat, the air-bags within one of the mat sections are inflated and deflated in such a sequence that an inflation/deflation frequency of all the air-bags contained within that section of the air-mat will be equal over any set period of time. In this manner, a uniform massage is assured as each air-bag within the section will inflate and deflate an equal number of times.

  • Patent number: 5520435
    Abstract: A reclining legless chair comprising an interlocking headrest constructed from a framework composed of a seat frame, back materials, and a headrest frame, which allows users to automatically set the inclining angle of the headrest which is interlocked to the angle between the seat and the back of the chair wherein the latter angle can be set in one of several steps at will by a user. The framework is made from a U-shaped seat frame, back materials and a headrest frame, in which both opening ends of the seat frame are connected to the straight rods of the back materials through a ratchet and the other ends of the rods are connected to both ends of a U-shaped headrest frame through interlocking mechanisms. The framework is suitably covered with elastic materials, is finished by covering the elastic materials with external cloth and permits the headrest frame to move interlockingly with the inclining angle of the back materials against the seat frame.

  • Patent number: 5460598
    Abstract: A chair-type polyfunctional automatic massager which can be used selectively for either a rubbing motion or a finger pressing motion, is driven by one motor and can provide 5 different kinds of movements selectively at will by making the starter apparatus installed in the back of a chair raise and lower. The massager is made up of a driving mechanism which can independently rotate two kinds of driven shafts depending on the direction of rotation of a main spindle rotated by a starter motor. A driven shaft is attached to a rubbing ball mechanism and another driven shaft is attached to a finger pressing mechanism, with both mechanisms linked to a starter device through a connecting mechanism provided between the two mechanisms. A raising and lowering mechanism for the unit is connected with a tapping spindle which can rotate in a forward or reverse direction and is linked to a motor for raising and lowering the unit.

  • Patent number: 5356369
    Abstract: A portable vibration finger pressure massager provides finger pressure massage to a body part of the user through the turning motion of massaging balls when the motor rotates in a first direction and simultaneously provides vibration and finger pressure massage when the motor rotates in an opposite direction. A weight change structure is attached to the rear shaft of the motor and becomes unbalanced when the motor rotates in the opposite direction, thereby causing the motor to vibrate. The vibration of the motor is transferred to projections provided on the massager thereby enabling the provision of vibration massage.

  • Patent number: 5352186
    Abstract: A finger pressure device for massaging includes a box having a pair of framelike slidable holding trunks provided on opposite sides thereof, a starting motor fixed in the center of the box and having a hollow starting shaft with a female screw part inside, and a T-shape supporting bar having a rear part with a supporting male screw part which engages with the female screw part of the starting motor. The forward part of the T-shape supporting bar has a pair of opposed finger pressure disks on opposite sides thereof. A pair of slidable holding plates can slide inside the slidable holding trunks and their ends are connected to the outer ends of holding parts of the finger pressure disks. The T-shape supporting bar extends and retracts by rotation of the starting shaft in one direction or the reverse direction, and each finger pressure disk extends and retracts repeatedly.
