Abstract: An electric razor comprises an apertured foil for (1) contact with skin being shaved, and an undercutter (23) urged against the foil and movable relative to the foil, in a direction parallel to a longitudinal axis of the foil, for shearing hairs that protrude through the foil apertures. The foil has a ridge (12) extending along the foil with first and second foil portions (8,9) forming respective flanks of the ridge. The cross-section of the foil is in a plane normal to the longitudinal axis and has an asymmetric arched profile. A first segment (5) of the cross-section taken through the first foil portion (8) has a radius of curvature in the range of 0.5 to 3.0 mm. A second segment (6) of the cross-section taken through the second foil portion (9) is contiguous with the first portion and has a radius of curvature in the range of 5 to 30 mm. The undercutter is in contact with the foil portions at both flanks of the ridge.

Abstract: A reciprocating shaver including an inner cutter upwardly pushing spring for pressing the inner cutter against the inner surface of the outer cutter; slide members held on the outer cutter frame so as to be able to slide; outer cutter elastically supporting members which are for elastically supporting the outer cutter and mounted in the outer cutter frame with one end of each one of them engaging one of the slide members, and another end thereof engaging the outer cutter; and float setting members which are provided in the shaver main body and respectively engage the slide members, in linkage with the mounting motion of the outer cutter frame relative to the shaver main body, so as to determine the position of the slide members.

Abstract: In a shaving apparatus (1) with a housing (2) and with a short-hair cutting device (30) projecting out of housing (2) and with a long-hair cutting device (36, 37) projecting out of housing (2), a common carrying device (45) is provided for the cutting devices (30, 36, 37), wherein the carrying device (45) is adjustable for height relative to the housing (2), so that all the cutting devices (30, 36, 37) can be adjusted for height together, and wherein there is a drive connection to a motor (16) of the shaving apparatus (1) in each operating position of the cutting devices (30, 36, 37) and consequently all the cutting devices (30, 36, 37) are drivable in each operating position of the cutting devices (30, 36, 37).

Abstract: An electric shaver includes a housing in which an electric drive for cutting knives of a shearing head is arranged. A shearing head frame is held by a first latching device in a position abutting on the housing and, upon release by the first latching device, is movable relative to the cutting knives into a position spaced apart from the housing against a stop. A second latching device is provided, by the release of which the shearing head frame is separately removable irrespective of the shearing head frame position released by the first latching device.

The tip end portion of upright member can protrude further toward the shaving surface than the end portions of the corner slits.

Abstract: An electric shaver having a cutter head that includes a movable cutter unit. With a single switching operation of a mode-switching dial that switches the operating mode of the shaver and is installed on the shaver main body, the movable cutter unit is moved upward or downward from a normal position, and the angle of inclination of the cutter head with respect to the shaver main body 1 is varied as well.

Abstract: 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.
