Abstract: A hair cutter of a shaving device has a support with a skin contacting surface, and a retainer releasably couplable to the support by a coupler to retain an external cutter in an operational/assembled condition of the hair cutter. A retained element of the external cutter is retained between a first retaining member of the retainer and a second retaining member of the support where, in response to manually turning the retainer relative to the support, the shaving surface protrudes relative to the skin contacting surface in the axial direction over an exposure distance. The coupler has a first guide on the support and a second guide on the retainer. The first and second guides mutually engage resulting from manually turning the retainer relative to the support when the retainer is in any angular position between first and second angular positions about the axis of rotation relative to the support.

Abstract: The invention relates to a shaving unit (11) for use in a shaving device (1). The shaving unit comprises a supporting member (19, 21a, 21b, 21c) and at least two hair cutting units (7a, 7b, 7c) supported by the supporting member. Each hair cutting unit comprises an external cutting member (25a) with hair-entry openings (31) and an internal cutting member (27a) which is rotatable relative to the external cutting member about an axis of rotation (41) and which has a plurality of hair-cutting elements (35). The shaving unit further comprises a retaining structure (23a, 23b, 23c) which is releasably couplable to the supporting member and which is configured to retain the at least two hair cutting units in an operational position relative to the supporting member in an assembled condition of the shaving unit.

Abstract: The invention relates to a hair cutting unit (7a) for use in a shaving device (1). The hair cutting unit comprises an external cutting member (21a) having a shaving surface (29) with hair-entry openings (31), and an internal cutting member (23a) which is rotatable relative to the external cutting member about an axis of rotation (41) and which has a plurality of hair-cutting elements (35). The hair cutting unit further comprises a supporting member (25a) having a skin contacting surface (43) surrounding the external cutting member, and a retaining component (27a) which is releasably couplable to the supporting member by means of a coupling structure (53, 55) and which is configured to retain the external cutting member in an operational position relative to the supporting member in an assembled condition of the hair cutting unit.

Abstract: An adjustment drive for an adjustable spacing comb for a hair cutting appliance that may be fitted with an adjustable spacing comb. The adjustment drive comprises an actuator for actuating a movable comb portion of the adjustable spacing comb with respect to a blade set of the hair cutting appliance, a manually operable rotation element, and a rotary encoder, that is configured to detect rotary movement of the rotation element and to output a respective user input signal, wherein the actuator is operated in response to the user input signal.

Abstract: The present disclosure relates to an adjustment drive (50) for an adjustable spacing comb (26) for a hair cutting appliance (10) and to a hair cutting appliance (10) that is fitted with an adjustable spacing comb (26). The present disclosure further relates to a method for operating an adjustable spacing comb (26) for a hair cutting appliance (10). The adjustment drive (50) comprises an actuator (52) for actuating a movable comb portion (40) of the adjustable spacing comb (26) with respect to a blade set (16) of the hair cutting appliance (10), a manually operable rotation element (64), particularly a manually rotatable rotation element (64) and an encoder (70) particularly a rotary encoder (70), that is configured to detect rotary movement of the rotation element (64) and to output a respective user input signal, wherein the actuator (52) is operated on the basis of the user input signal.
