The support structure may include a plurality of ring-like, curved swivel rails attached to and projecting from a bottom surface of the cutter system opposite to the skin contact surface thereof. Such curved swivel rails define the swivel axis and may be movably received in shell bearings of a lower support frame structure that may be attached to a handle of the hair cutter.

Abstract: The present invention is a personal care device comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to the handle for effecting a personal care treatment to the body surface, wherein an adjustment device including at least one adjustment actuator is provided for adjusting at least one treatment characteristic, wherein the adjustment actuator is configured and controlled to adjust the at least one treatment characteristic from a first setting to a second setting within a transition time period of not less than 0.1 seconds and not more than 1.5 seconds.

Abstract: The present invention relates to the field of small electrical appliances such as battery powered electrical appliances for personal hygiene, in particular to a hair removal device such as an electric shaver or epilator as well as an electric toothbrush. The small electrical appliance comprises an electric load, wherein the electric load heats up during operation; a measuring circuitry for measuring an electrical parameter of the electric load; a temperature sensor arranged spatially separated from the electric load; and control circuitry adapted to protect the electric load from overheating by controlling the electric load based on the electrical parameter of the electric load and an output of the temperature sensor.

Abstract: The present invention relates to a hair cutter such as electric shaver and/or electric trimmer, having an eccentric attachment of the leaf spring to the cutter unit and the asymmetric layout of the spring mechanism, allowing the clastic support structure of the at least one cutter unit to be configured to provide for a symmetric self-adaption, in particular symmetric micro diving and/or micro tilting.

Abstract: The present invention relates to a hair cutter such as electric shaver and/or electric trimmer, comprising a suspension spring mechanism including at least one elongated leaf spring which is rigidly attached, with one end portion, to a first end portion or edge portion of a cutter unit and, with another end portion, to a cutter head frame at a spring support portion thereof adjacent to a second end portion or edge portion of the cutter unit opposite to the first end portion or edge portion thereof. Despite such eccentric attachment of the leaf spring to the cutter unit and the asymmetric layout of the spring mechanism, the elastic support structure of the at least one cutter unit nevertheless may be configured to provide for a symmetric self-adaption, in particular symmetric micro diving and/or micro tilting.

Abstract: The present invention relates to a personal care device, in particular hair removal device such as an electric shaver, comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, wherein an adjustment device including at least one adjustment actuator is provided for adjusting at least one treatment characteristic, wherein said adjustment actuator is configured and controlled to adjust said at least one treatment characteristic from a first setting to a second setting within a transition time period of not less than 0.1 seconds and not more than 1.5 seconds.

Abstract: The present invention relates to a personal care device, in particular hair removal device such as an electric shaver, comprising an elongated handle for manually moving the personal care device along a body surface, a working head attached to said handle for effecting a personal care treatment to said body surface, said working head being movably supported relative to said handle and/or including a working head element being movably supported relative to a working head basis to allow adaption of the working head and/or of the working head element to the body surface contour, wherein an adjustment device is provided for adjusting a movability characteristic of a suspension of said working head and/or of said working head element, wherein said adjustment device includes at least one actuator for adjusting at least one characteristic.

Abstract: A hair removal device, in particular an electric shaver, comprising a working head attached to a handle for moving the working head along a skin surface, said working head including at least a pair of short hair cutters and at least one trimmer neighboring at least one of said short hair cutters, wherein said short hair cutters and said trimmer are movable relative to said handle under a skin contact pressure.

Abstract: The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a drive unit having first and second drive components adapted to magnetically interact with each other, and a magnetic shielding at least partially surrounding the drive unit. Said magnetic shielding is formed by structural parts supporting the drive unit and/or transmitting drive movements of the drive unit, wherein such structural parts are made of a soft magnetic material. More particularly, a mounting frame and a transmitter frame together form a magnetic shielding cage which is movable as the mounting frame and the transmitter frame are movable relative to each other.
