A hair cutting device includes a grip, a head disposed external to one end of the grip, the head including a cutting unit that works on hair, and a joint connecting the grip and the head. The joint includes a base connected to one of the grip and the head, and a slide portion connected to the other of the grip and head and held to be slidable within a predetermined area on a slide plane that is a plane intersecting an alignment of the grip and the head. Accordingly, the hair cutting device including the head that has an excellent ability to lessen impact which is made when the head hits the skin and to follow the skin surface is provided.

The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other by a spring device and adapted to magnetically interact with each other. Said spring device includes at least one leaf spring having a constricted section in a central region of the leaf spring, wherein surfaces of said at least one leaf spring neighboring said constricted section are shaped convex. Such convex surfaces may have a parabolic contour.

According to an aspect, there is provided a mounting assembly (10) for a hair cutting appliance. The mounting assembly comprises: a head (12) for receiving a cutting unit; a base (14) and a mount. The head is mounted to the base via the mount such that the head is pivotably moveable relative to the base about a primary axis (15) and a secondary axis (30), wherein the primary axis and the secondary axis are not parallel. A first biasing element (34a) and a second biasing element (34b) act independently of one another, wherein the first biasing element and the second biasing element are mounted at a fixed point and configured to act on the head or the mount at a respective first biasing point (40a) and second biasing point (40b) to bias the pivoting movement of the head with respect to the base to a stable position. The first biasing point and the second biasing point are located on the same side of a primary plane (50) which comprises a biasing axis (24a), parallel to the primary axis, about which the first biasing point and the second biasing point are constrained to pivot relative to the fixed point, and a line parallel to a force direction (52) defined by a biasing force applied at one of the first biasing point or the second biasing point, to bias the head in one pivoting direction to the stable position with respect to the base about the primary axis. The first biasing point and the second biasing point are located on opposing sides of a secondary plane (60) which comprises the secondary axis and a line parallel to the force direction, to balance the head in the stable position with respect to the base about the secondary axis.

According to an aspect, there is provided a mounting assembly 20 for a hair cutting appliance 10, the mounting assembly comprising: a head 24 configured to receive a cutting unit 14; a base 22 coupled to the head; a pivoting mechanism 30 coupling the base to the head, wherein the pivoting mechanism is configured to permit pivoting movement of the head relative to the base about a head pivot axis 50; and a rotatable locking element 40 configured to be rotated between: an engaged position, in which the locking element obstructs pivoting movement of the head to thereby lock the head in a locked position about the head pivot axis, and a disengaged position in which the locking element does not obstruct pivoting movement of the head such that the head is freely pivotable relative to the base about the head pivot axis; wherein the locking element is configured such that rotating the locking element to the engaged position drives the head into the locked position.

According to an aspect, there is provided a mounting assembly (10) for a hair cutting appliance, the mounting assembly comprising: a head (12) configured to receive a cutting unit; and a base (14), wherein the head is mounted to the base via a pair of arms (16) to form a linkage. Each arm is coupled at a joint (18) to a head coupling (20) on the head, and coupled at a joint to a respective base coupling (22) on the base. The base couplings are spaced apart along a movement line, and each joint is configured to permit pivoting movement about parallel pivot axes. A stroke limiter (26) is configured to obstruct pivoting movement of the head relative to the base beyond a limit. At least one of the base couplings is a flexible base coupling which is elastically mounted to a body (38) of the base such that the respective flexible base coupling is moveable relative to the body in a direction having a component which is parallel to the movement line and away from the other base coupling, to permit pivoting movement of the head relative to the base beyond the limit imposed by the stroke limiter.

Electric shaver includes body, head having blade block, and head supporting part connecting body with head. Head supporting part includes swing supporting part supporting head swingably about two swing axes, and head float part so that head is movable up and down with respect to body. This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.

A shaver is disclosed that comprises a handle (12) and a cutting head (13) that are arranged to move relative to each other via a rotational and/or translational axis (16,17). This movement facilitates skin contour following during shaving to achieve a close cut. The handle (12) comprises a laser source that emits a laser beam and the shaver has an optical system that includes optical elements (23,25,26,37,40,42) to direct a part of a laser beam so that it coincides with the rotational axis and/or is parallel to the translational axis. In this way, when the cutting head (13) is moved the optical alignment between the laser source, optical elements (23,25,26,37,40,42) and cutting zone (28) does not change.

A hair cutting appliance includes a mounting unit configured to couple a cutting unit to a housing. The mounting unit includes a swivel mechanism having a base portion configured to be coupled to the housing, and a top portion configured to be coupled to the cutting unit, where the base and top portions are movable with respect to each other, such that, during operation, the cutting unit is pivotably supported by the swivel mechanism, which defines a virtual pivot axis for the cutting unit. The virtual pivot axis is substantially parallel to a cutting edge of the cutting unit. In a first or shaving state of the swivel mechanism, the virtual pivot axis is located at a first position with respect to the cutting unit, and in a second or styling state, the virtual pivot axis is located at a second position that is different from the first position.

The present invention relates to electric shavers, handpieces of such shavers and a method of manufacturing such electric shavers. More particularly, the present invention relates to a shaver set comprising a plurality of electric shavers.

Electric shaver provided with a handle and a shaver head including at least one cutter element, wherein said shaver head is connected to said handle by means of a support structure providing for a swivel and/or tilting axis about which said shaver head may swivel or tilt relative to said handle, wherein said cutter element is drivable by a drive unit in an oscillating manner along a cutter oscillation axis, said drive unit including an elongated drive transmitter coupled to said cutter element.
