Patent number: 7334338Abstract: A reciprocatory dry shaver has a shaving head carrying an outer cutter, and an inner cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which carries a joint for driving connection to the inner cutter. Resilient coupling links are provided to support the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its upper end coupled to the oscillator and has its lower end which is farther away from the inner cutter than the oscillator and is anchored to the shaving head. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter.Type: GrantFiled: July 27, 2005Date of Patent: February 26, 2008Assignee: Matsushita Electric Works, Ltd.Inventors: Takeshi Shiba, Ryo Motohashi, Hidekazu Yabuuchi, Hiroaki Shimizu

Publication number: 20080034591Abstract: A shaving device includes an assembly to better maintain the cutting blades in contact with the skin during shaving. A swivel ball joint is preferably located between the shaver head and the housing and enables the head of the shaver to move in any direction from a longitudinal axis through the shaving device. A positioning spring connected to the ball joint and the housing is biased toward the center axis of the shaver and provides a swivel action that causes the shaver head to return back to its center position after adjustment of the head's angle. A motion transfer spring transfers the motor action to the upper shaving mechanism at any angle or direction that the shaver head may be in at any time. As the shaver head changes angles to match the contour of the user's body, the motion transfer spring flexes to follow the angles of the shaver head. This transfers the motion of the motor to the eccentric cam, which helps to control the motion of the trimmers.Type: ApplicationFiled: August 8, 2006Publication date: February 14, 2008Inventor: Kam Fai Fung

Publication number: 20080016694Abstract: An electric shaver includes net-shaped outer blades; and inner blades sliding reciprocally over an inner side of the outer blades as detachably connected with driving units driven by a motor. Each of the inner blades includes a blade plate having an inversed-like-U shape seen from a longitudinal direction in parallel with a reciprocating sliding direction; and a blade holder having attaching portions to be attached to the blade plate in longitudinally defined end regions, wherein connection portions to be detachably connected with the driving units are provided at the blade holder in a longitudinally defined center region, and, when dissembling the blade holder from the driving units, anti-detach portions are provided to thereby prevent separation of the blade holder in the longitudinally defined center region from the blade plate in the longitudinally defined center region due to a tensile load between the connection portions and the driving units.Type: ApplicationFiled: July 13, 2007Publication date: January 24, 2008Applicant: Matsushita Electric Works, Ltd.Inventors: Masaaki Sato, Shunsuke Komori, Takeshi Shiba, Jyuzaemon Iwasaki
