20160089799 | ROTARY ELECTRIC SHAVER - A rotary electric shaver includes an outer blade whose upper surface functions as annular shaving surfaces and having multiple hair inlets formed therein, and an inner blade that has a small blade which rotates while coming into sliding contact with a lower surface of the outer blade from below the annular shaving surfaces and. At least a portion of the multiple hair inlets is formed in an elongated hole shape extending along a radial direction of the annular shaving surfaces and, and an end portion (alternatively, both end portions and) in the radial direction has a widened portion (alternatively, and) which is open wider in a circumferential direction than a central portion. | 03-31-2016 |
20160082607 | ROTARY ELECTRIC SHAVER - There is provided a rotary electric shaver whose outer blade can smoothly move along skin, which can reliably catch any type of hair, and which can prevent the skin from being damaged due to deep shaving. | 03-24-2016 |
20160039102 | RECIPROCATING-TYPE ELECTRIC SHAVER - A reciprocating-type electric shaver includes a head unit that is arranged so as to be capable of oscillating at least forward to and rearward from a main body. The head unit has multiple blade units whose inner blades and come into sliding contact with an inner surface of outer blades and reciprocate rightward and leftward. At least one of the blade units is configured to serve as a movable blade unit which is held by a blade frame of the head unit so as to be vertically movable from the reference position between a predetermined upper position and a predetermined lower position, and the blade frame has a positioning lever which performs positioning by moving the movable blade unit to a desired position. | 02-11-2016 |
20150343652 | ROTARY ELECTRIC SHAVER - There is provided a rotary electric shaver which can improve cutting quality and can prevent a blade edge from becoming blunt. | 12-03-2015 |
20150033817 | PRESSING TOOL AND LOCKING BOLT - A pressing tool in which, according to work content, an exchange tool is held so as to be capable of being exchanged by attachment/detachment by a locking bolt penetrating through a mounting portion provided to the tool main body, and the exchange tool is actuated by a pressing member. The outer periphery of the shank of the locking bolt is provided with: an annular groove for locking, arranged on the bolt-head side so as to be partially discontinuous; a release groove extending from the discontinuous part of the annular groove toward the tip of the bolt along the shank at an incline so as to gradually get shallower; and a retaining annular groove formed on the shank further toward the tip of the bolt than the release groove, the bolt-head side inner wall of the retaining annular groove being formed as a tapered incline. The mounting part is provided with a locking pin that fits into the locking annular groove, the release groove, and the retaining groove and that is capable of moving between the grooves. The locking bolt is provided with a release coil spring for urging the bolt toward the bolt head. | 02-05-2015 |
20140352152 | ROTARY ELECTRIC SHAVER - In a rotary electric shaver according to the present invention, a plurality of blade units that include an outer blade having an annular shaving surface on an upper surface and an inner blade rotating in sliding contact with a lower surface of the outer blade are arranged in a head unit held by a main body so as to be tiltable. A main drive shaft outputting drive force of a motor accommodated in the main body and a rotary shaft of any one blade unit out of the plurality of blade units are connected by a movable joint, and a position of the movable joint serves as a tilting fulcrum for tilting the head unit. | 12-04-2014 |
20140165407 | ROTARY ELECTRIC SHAVER - A rotary electric shaver with an outer cutter having a circular shaving top surface with numerous hair introduction openings and an inner cutter having a small cutter slidably rotating in contact with a bottom surface of the outer cutter. The rotary electric shaver includes an outer cutter set wherein the outer cutter is assembled in an outer cutter holding unit and an inner cutter set wherein the inner cutter is assembled in an inner cutter holding unit. The outer cutter set and the inner cutter set are respectively provided with a positioning convex portion on one and a positioning concave portion on the other. The positioning convex portion can fit in the positioning concave portion such that the outer cutter set can be assembled with the inner cutter set only in a case where the outer cutter set and the inner cutter set are in a predetermined assembly position. | 06-19-2014 |
20140157957 | METHOD OF MANUFACTURING OUTER CUTTER OF ROTARY ELECTRIC SHAVER - A method of manufacturing an outer cutter of a rotary electric shaver that includes the outer cutter and an inner cutter which is slidingly in contact with a bottom surface of the outer cutter and rotates, in which a plurality of the circular shaving surfaces are integrally formed in the outer cutter in a concentric manner, and round hole-shaped hair introduction openings are formed in at least one of the circular shaving surfaces includes (a) a step of grinding or polishing a predetermined position where the round hole-shaped hair introduction openings are formed in the circular shaving surface to obtain a thickness size smaller than an inner diameter size of the round hole; and (b) a step of forming the round hole-shaped hair introduction openings in the position where the grinding or the polishing is performed by pressing, after the step (a). | 06-12-2014 |
20130180112 | ROTARY ELECTRIC SHAVER - A rotary electric shaver includes an outer cutter case secured to the outer periphery of an outer cutter and having a sliding surface formed on the outer periphery. An outer cutter case holder is fitted in a mounting port to vertically move with an upper limit position restrained and pivotably holds the outer cutter case to guide the sliding surface. A pushup plate imparts an upward return tendency to an outer cutter case assembly including the outer cutter, the outer cutter case and the outer cutter case holder. The outer periphery of the outer cutter case is provided with a projection extending to the upper surface of the outer cutter frame, serving as a stopper which prevents the outer cutter case from sinking into the mounting port. This arrangement prevents the outer cutter from being caught by the inner edge of the mounting port and improves shaving performance. | 07-18-2013 |
20120110854 | ROTARY ELECTRIC SHAVER - A rotary electric shaver includes an outer cutter which has an upper surface with annular shaving faces, in which many hair-entry apertures are formed, and an inner cutter having small blades, which rotate in sliding contact with the lower surface of the outer cutter from below the shaving faces. The outer cutter ( | 05-10-2012 |
20120110853 | ROTARY ELECTRIC SHAVER AND MANUFACTURING METHOD OF OUTER CUTTER AND INNER CUTTER OF THE SAME - A rotary electric shaver includes an outer cutter having an upper surface with annular shaving sections, formed with hair entry apertures, and an inner cutter having small blades, which rotate in sliding contact with the outer cutter from below the shaving sections. The outer cutter has a plurality of concentric annular shaving sections. The shaving section adjacent to an outer periphery is lower than the shaving section adjacent to a center. The shaving sections are formed on a plane horizontal to a central axis. This makes it possible to increase a shaving area, to precisely trace the curved surface of a concave portion of skin and to come in contact with the skin with a proper contact pressure, thus permitting smooth shaving of the concave portion. The shaver has a simple structure with a smaller number of components, featuring easier assembly and easier removal of hair bits. | 05-10-2012 |
