摘要： The invention relates to a shaving unit for a shaving apparatus, comprising at least two cutting units (10a, 10b), wherein the cutting units each comprise an external cutting member (12) having a plurality of hair entry openings (13) and an internal cutting member (480) which is rotatable relative to the external cutting member about an axis of rotation. The cutting units each comprise a housing (20) accommodating a hair collection chamber, the housing comprising a base portion (551) and a cover portion (530) which is releasably coupled to the base portion, wherein the external cutting member and the internal cutting member are held in an operating position in the cover portion by means of a holding component (517) which is releasably coupled to the cover portion. The housing of each cutting unit has a closed condition, wherein the cover portion holding the external cutting member and the internal cutting member is coupled to the base portion and closes the hair collection chamber, and an opened condition, wherein the cover portion is at least partially released and at least partially removed from the base portion so that the hair collection chamber is accessible. The base portion of the housing of each cutting unit comprises a supporting structure (519), wherein in the closed position of the housing the external cutting member is directly supported by the supporting structure at least in an axial direction parallel to the axis of rotation. The supporting structure provides a direct transfer of axial forces, exerted on the external cutting member during use, to the base portion of the housing. Thereby, the mechanical load on the holding component is substantially reduced.

摘要： 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.

摘要： The invention relates to a hair-cutting unit for a shaving device. The hair- cutting unit comprises a hair-cutting element and a telescopic drive-shaft mechanism (3). The drive-shaft mechanism comprises a first shaft-segment (21), which is in telescopic engagement with a co-rotating second shaft-segment (22), which is in telescopic engagement with a co-rotating third shaft-segment (23). A spring mechanism (5) presses the first 5 telescopic shaft-segment and the third telescopic shaft-segment away from one another. In an embodiment, the first and second telescopic shaft-segments (21, 22) are in mutual tiltable engagement and/or the second and third telescopic shaft-segments (22, 23) are in mutual tiltable engagement. The invention provides improved skin-contour-following capacity of a shaving device, while at the same time the required installation space for the drive-shaft 10 mechanism remains restricted.

摘要： A hair-cutting unit (4) for use in a hair-cutting appliance comprises cutting members (41, 42), a base member (5), and a supporting member (6) which is pivotable relative to the base member (5) and accommodates the cutting members (41, 42). The hair-cutting unit (4) further comprises a holding member (7) which is pivotable relative to the supporting member (6) between a holding position of holding the cutting members (41, 42) in an operational position in the supporting member (6), and a releasing position of releasing the cutting members (41, 42) for removal from the supporting member (6), and a biasing mechanism (8) which is configured to bias the holding member (7) towards the holding position. At least in an opened position of the supporting member (6), pivoting of the holding member (7) out of the holding position is prevented solely by the biasing force of the biasing mechanism (8).

摘要： A shaver head (12) for an electric shaver (10) has at least two hair-cutting units (13), each comprising an external cutting member and an internal cutting member which is rotatable relative to the external cutting member, and each supported by a supporting portion (26). The supporting portion is linearly movable under the bias of a spring member (30) relative to a base portion (20) of the shaver head between a first, retracted, position and a second, extended, position. The shaver head has a locking mechanism (30, 32) for selectively locking the supporting portion in a locked position relative to the base portion. This allows a user to select different shaving modes.

摘要： A shaving unit (12) has an assembly of at least two rotary hair-cutting units (13) and a supporting member (26) to which the hair-cutting units are connected. The assembly of the hair-cutting units and the supporting member can move linearly relative to a base portion (20) between a first, retracted, position and a second, extended, position. The supporting member is biased by a spring member (30) away from the base portion. The hair-cutting units each have an individual hair- collecting chamber and they are individually pivotable relative to the supporting member. The base portion comprises a coupling structure (44) by means of which the shaving unit can be releasably coupled to the main housing (15) of a shaving device.

摘要： According to an aspect, there is provided a mounting assembly (12) for a hair cutting appliance, the mounting assembly comprising a head (16) for receiving a cutting unit (14); and a body (18). The head is mounted to the body by a four-bar linkage (20) having a coupler link (22) associated with the head, a frame link (24) associated with the body, and two arms (26) extending therebetween. The frame link is connected to each arm at respective joins (28), and the coupler link is connected to each arm at respective joins. Pivoting movement of the arms about parallel linkage axes (30) passing through each join permits rotation of the coupler link relative to the frame link about a virtual pivot (32). One of the coupler link and the frame link is a first link coupled to the arms by two-degree-of-freedom joins, thereby permitting the arms and the other of the frame link and the coupler link to further pivot in unison relative to the first link about a rotation axis (34) perpendicular to the linkage axes.

摘要： For releasably coupling a body and a head of a personal care appliance, a coupling assembly is provided which comprises a coupling element and a retaining member. One of the coupling element and the retaining member comprises at least one cam element (55) and another of the coupling element and the retaining member comprises at least one notch (46). Both the cam element (55) and the notch (46) have two oppositely sloped surfaces (48; 57). In a coupled position of the coupling assembly, the cam element (55) and the notch (46) only contact each other at two sides through their sloped surfaces (48; 57) at the position of a contact portion (55a) at a base of the cam element (55) and an associated contact portion (46a) of the notch (46) at an open side of the notch (46).
