Patent number: 6083180Abstract: 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.Type: GrantFiled: July 24, 1998Date of Patent: July 4, 2000Assignee: Daito Electric Machine Industry Company LimitedInventor: Nobuzo Shimizu

Patent number: 5305738Abstract: 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.Type: GrantFiled: May 22, 1992Date of Patent: April 26, 1994Assignee: Daito Electric Machine Industry Company LimitedInventor: Nobuzo Shimizu

Patent number: 3978314Abstract: 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.Type: GrantFiled: November 7, 1974Date of Patent: August 31, 1976Inventor: Nobuzo Shimizu
