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.

Hair cutting unit having a coupling structure

The invention relates to a shaving unit () for use in a shaving device (). The shaving unit comprises a supporting member () and at least two hair cutting units () supported by the supporting member. Each hair cutting unit comprises an external cutting member () with hair-entry openings () and an internal cutting member () which is rotatable relative to the external cutting member about an axis of rotation () and which has a plurality of hair-cutting elements (). The shaving unit further comprises a retaining structure () 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. The retaining structure comprises, for each respective hair cutting unit of the at least two hair cutting units, a separate retaining member () which is releasably couplable to the supporting member and which is configured to separately retain the respective hair cutting unit in an operational position relative to the supporting member independently from any other of the at least two hair cutting units. The retaining structure further comprises, for each respective hair cutting unit of the at least two hair cutting units, a locking member () comprising at least one locking element () which, in the assembled condition of the shaving unit, is biased by spring force towards the external cutting member of the respective hair cutting unit and engaged by an engagement element () of the external cutting member to prevent rotation of the external cutting member about the axis of rotation. The locking member provided for the respective hair cutting unit is separately arranged from any other locking member, provided for any other of the at least two hair cutting units, and integrated with the separate retaining member provided for the respective hair cutting unit.
