Abstract: 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.

Abstract: According to an aspect, there is provided a comb attachment for a blade system, the comb attachment comprising a rack component and a pinion assembly. The rack component is defined by one of a comb and a housing and comprises a rack. The housing is configured to attach to the blade system, and the pinion assembly comprises a pinion component defined by the other of the comb and the housing. The pinion assembly further comprises an axle retained by the pinion component, and a pinion disposed on the axle such that the pinion is rotatable with respect to the pinion component. The rack and the pinion are arranged to cooperate such that rotation of the pinion on the axle induces relative linear movement between the comb and the housing. The comb attachment comprises a locking mechanism configured to rotationally lock the pinion, comprising a protrusion on one of the pinion and the pinion component, and a notch on the other of the pinion and the pinion component, the protrusion and notch being configured to engage to lock the pinion to thereby prevent relative linear movement between the comb and the housing. The pinion is moveable between a locked position, in which the protrusion and the notch are engaged, and an unlocked position, in which the protrusion and the notch are disengaged. The pinion is biased away from the rack and towards the locked position, such that pushing the pinion towards the rack and the unlocked position causes disengagement of the notch and protrusion to permit rotation of the pinion.

Abstract: 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.
