Patent number: 7832104Abstract: The invention provides a hair removing apparatus having a body hair treatment head removing a body hair by shaving the body hair, depilating the body hair or cutting the body hair, and a main body grip held by a hand, and in which the body hair treatment head being rotatably coupled to the main body grip in such a manner that the body hair treatment head is freely oscillated with respect to the main body grip. In this structure, the hair removing apparatus is provided with a weight applying means for applying a force opposing to a force by which the body hair treatment head is oscillated by its own weight of the body hair treatment head around a center of rotation of the body hair treatment head.Type: GrantFiled: December 16, 2005Date of Patent: November 16, 2010Assignee: Panasonic Electric Works Co., Ltd.Inventors: Masanobu Yamasaki, Toshiyuki Tsushio, Takeshi Shiba, Juzaemon Iwasaki

Patent number: 7461456Abstract: A dry shaver includes a swingable shaving head which is provided with a pair of support points through which the shaving head is supported to a grip through a linkage mechanism. The linkage mechanism includes a pair of cranks each connected at its one end to each one of the support points and connected at the other end to each one of the anchor points on the side of the grip. A frame projects on top of the grip in an overlapping relation with the shaving head to give the anchor points which are positioned upwardly of the support points with respect to a height axis of the grip for suspending the shaving head an top of the grip by the frame.Type: GrantFiled: December 17, 2004Date of Patent: December 9, 2008Assignee: Matsushita Electric Works, Ltd.Inventors: Toshiyuki Tsushio, Jyuzaemon Iwasaki, Takeshi Shiba, Masanobu Yamasaki

Publication number: 20070261249Abstract: The invention provides a hair removing apparatus having a body hair treatment head (A) removing a body hair by shaving the body hair, depilating the body hair or cutting the body hair, and a main body grip (2) held by a hand, and in which the body hair treatment head (A) being rotatably coupled to the main body grip (2) in such a manner that the body hair treatment head (A) is freely oscillated with respect to the main body grip (2). In this structure, the hair removing apparatus is provided with a weight applying means (100, 110, 120, 130, 140) for applying a force opposing to a force by which the body hair treatment head (A) is oscillated by its own weight of the body hair treatment head (A) around a center (81) of rotation of the body hair treatment head (A).Type: ApplicationFiled: December 16, 2005Publication date: November 15, 2007Applicant: MATSUSHITA ELECTRIC WORKS, LTD.Inventors: Masanobu Yamasaki, Toshiyuki Tsushio, Takeshi Shiba, Juzaemon Iwasaki

Patent number: 7234239Abstract: A hair removing device with a lotion applicator includes a housing, a hair removing head mounted to the housing and adapted to be held against a user's skin for hair depilation or hair epilation, an applicator which dispenses a lotion on the user's skin, a tank holding the lotion and a lotion supply mechanism for supplying the lotion from the tank to the applicator. The lotion supply mechanism includes a regulating device, which regulates an amount of the lotion being dispensed from the applicator. The lotion supply mechanism includes a powered pump for expelling the lotion from the tank to the applicator. The regulating device includes a handle for varying pump capacity of the powered pump. The applicator is incorporated into a head frame forming a part of the hair removing head with the head frame being detachable from the housing.Type: GrantFiled: February 12, 2003Date of Patent: June 26, 2007Assignee: Matsushita Electric Works, Ltd.Inventors: Atsuhiro Saito, Hirokazu Kato, Jyuzaemon Iwasaki, Hideki Tanaka, Koutarou Yanagi, Yasunori Ueda, Toshiyuki Tsushio, Masanobu Yamasaki, Youji Urano, Harunori Kitahara

Publication number: 20060021228Abstract: A dry shaver includes a hand grip and a shaving head supported to the grip. The shaving head carries a foil cutter unit composed of an outer foil and an inner cutter driven to move relative to the outer foil in hair shearing engagement therewith. The outer foil is elongated to have a length and a width, and is arcuately curved along its length. The shaving head is movably supported to the grip so as to be tiltable about a transverse axis parallel to the width of the outer foil. Thus, when the shaving head is pressed against the skin as being inclined, the shaving head is allowed to tilt in a direction of reducing a contact pressure which would otherwise be greater at one longitudinal end than at the other longitudinal end. Therefore, the shaving head can be free from undue dragging at either of the longitudinal ends of the outer foil to be thereby guided smoothly across the skin surface for efficient and comfortable shaving.Type: ApplicationFiled: July 27, 2005Publication date: February 2, 2006Inventors: Takeshi Shiba, Toshiyuki Tsushio, Masanobu Yamasaki, Jyuzaemon Iwasaki

Publication number: 20050138821Abstract: A dry shaver with a swingable shaving head which is capable of following a user's skin smoothly while keeping an optimum pressing relation with the skin. The shaver includes a grip and a shaving head mounted on top of the grip. The shaving head has a cutting face on its top and has a pair of support points through which the shaving head is supported to the grip. A linkage mechanism is provided to couple the shaving head to the grip for allowing the shaving head to swing relative to the grip. The linkage mechanism includes a pair of cranks each connected at its one end to each one of the support points and connected at the other end to each one of the anchor points on the side of the grip. A frame projects on top of the grip in an overlapping relation with the shaving head to give the anchor points which are positioned upwardly of the support points with respect to a height axis of the grip for suspending the shaving head on top of the grip by the frame.Type: ApplicationFiled: December 17, 2004Publication date: June 30, 2005Inventors: Toshiyuki Tsushio, Jyuzaemon Iwasaki, Takeshi Shiba, Masanobu Yamasaki

Publication number: 20050131427Abstract: An improved hair removing device is capable of controlling a dispensing amount of the lotion to give the lotion adequately as intended by a user for comfortable hair treatment. The device includes a housing carrying a hair removing head adapted to be held against a user's skin for hair depilation or epilation. The device further includes an applicator for dispensing the lotion on the user's skin, a tank holding the lotion, and a lotion supply mechanism for supplying the lotion from the tank to the applicator. The lotion supply mechanism is provided with a regulating means which regulates an amount of the lotion being dispensed from the applicator.Type: ApplicationFiled: February 12, 2003Publication date: June 16, 2005Inventors: Atsuhiro Saito, Hirokazu Kato, Jyuzaemon Iwasaki, Hideki Tanaka, Koutarou Yanagi, Yasunori Ueda, Toshiyuki Tsushio, Masanobu Yamasaki, Youji Urano, Harunori Kitahara

Patent number: 6568083Abstract: A dry shaver is capable of being depressed equally at different positions but with differing contact pressures between outer and inner cutters. The shaver has a housing having a motor and inner and outer cutters at its upper end. The inner cutter is driven by the motor to move in shearing engagement with the outer cutter for shaving hairs. The inner cutter is urged upwardly by a bias spring to develop a contact pressure against the outer cutter. The outer cutter is carried by a cutter holder movably supported to a head frame mounted on top of the housing. The shaver has a height adjust mechanism for adjusting the height of the head frame relative to the housing between a high position and a low position while compressing the spring differently to vary the contact pressure, and for allowing the cutter holder to be depressed relative to the head frame from each of the height and low positions.Type: GrantFiled: July 19, 2001Date of Patent: May 27, 2003Assignee: Matsushita Electric Works, Ltd.Inventors: Fumio Taniguchi, Toshiyuki Tsushio, Yasunori Ueda, Masanobu Yamasaki, Takeshi Shiba, Jyuzaemon Iwasaki, Mitsuhiro Kadowaki, Hirokazu Kato, Mikihiro Yamashita, Yasuo Ibuki, Atsushi Takahashi
