  • Patent number: 7322949
    Abstract: A lower-limb massage machine is provided with a stand having an upper stand member disposed on an upper portion of a lower stand member to be placed on a floor surface, and a casing. The casing has a pair of right and left recess portions, on its face side, extending in a front-and-rear direction so that lower limbs are fitted in the recess portions, respectively. The casing is supported rotatably around an axis extending in a right-and-left direction with respect to the upper stand member, a massage mechanism incorporated in the casing for massaging the lower limbs. Also provided is an attitude holding mechanism for holding the casing at an attitude with respect to the upper stand member to which the casing is rotated. Accordingly, the attitude and height of the casing of the lower-limb massage machine can easily adjusted.

  • Patent number: 6629940
    Abstract: A lower leg massager is constructed in such a manner that the lower leg can be massaged over a wide range without arranging a plurality of massaging members along the length thereof. Right and left massaging members formed of elongated boards are arranged in an opposed manner so a lower leg can be fit therebetween. A driving mechanism is provided for moving the massaging members toward and away from each other so that the longitudinal directions thereof are inclined in opposite directions with respect to each other, and changing the extent of longitudinal inclination when moving the massaging members toward and away from each other.

  • Patent number: 6083180
    Abstract: A massaging device is so arranged to allow a massaging member thereof to simultaneously perform a vibrating action and a kneading action on the same body part to be massaged, and not to require any increase in the size thereof. The present invention provides a vibrator-type massaging device including a casing and a vibrating plate provided on top of the casing so as to vibrate at a high speed. A massaging member is provided on the vibrating plate and includes a top surface serving as a contact surface for contact with a human body. A kneading means having a pair of kneading balls which swing in the same plane as that of the contact surface of the massaging member is provided inside the casing so as to knead a human body.

  • Patent number: 5685827
    Abstract: Conventional roller massaging devices can perform only massage resulting from rolling action and cannot perform combinational massage resulting from both kneading action and the rolling action. In view of the foregoing, the present invention provides a massaging device which can perform massage resulting from either the kneading action or the rolling action.

  • Patent number: 5305738
    Abstract: A massage device having kneading balls includes a vibrating device provided between each of the kneading balls and a connecting member for vibrating the ball. The connecting member is a spring, such as a coiled spring, which is elastically deformable in a direction perpendicular to its axis. The connecting member is attached to a rotary plate rotatable inside a housing, eccentrically with respect to the rotary plate and rotatable relative thereto. The housing is further provided therein with a rotation control device for preventing the connecting member from rotating about its own axis with the rotation of the rotary plate. This prevents the vibrating device on the connecting member and the kneading ball from rotating with the rotation of the rotary plate.

  • Patent number: 3978314
    Abstract: A hand held hair drier includes a cylindrical heater sleeve longitudinally coupled to a main body provided with a handle extending normally therefrom. The handle includes first and second windows of different, readily distinguishable colors positioned at a location above the normal gripping portion thereof. A pair of switches arranged to be operated by a two position push button located in the handle and arranged to selectively energize an electric heater in the heater sleeve and/or an electric motor driven fan in the main body through first and second circuit each provided with a signal lamp arranged adjacent a respective one of the different colored windows. When the push button is activated to the first position one switch is closed and the fan is energized to blow unheated air and one of the lamps is lit to illuminate a window. When the push button is activated to the second position both the heater and fan are energized so that heated air is delivered and both lamps are lit to illuminate both windows.
