Abstract: The present invention relates to a drive train (50) of a hair cutting appliance (10) and to a self-aligning coupling linkage (66) for a drive train (50). The coupling linkage (66) comprises a driving shaft and a non-aligning output shaft (56), said coupling linkage (66) comprising: a first driving coupling element (78) arranged to be driven by a driving shaft (54), particularly by a motor shaft, a transmission shaft (70), particularly a rigid transmission shaft (70), comprising a first drivable coupling element (80) at a first end and a second driving coupling element (86) at a second end thereof, wherein first driving coupling element (78) engages the first drivable coupling element (80) for rotatingly driving the transmission shaft (70), thereby forming a first pivoting joint (76), wherein the second driving coupling element (86) is arranged to engage a second drivable coupling element (88) of an output shaft (56), wherein the first driving coupling element (78) and the first drivable coupling element (80) define a male connector comprising an external polygonal profile (90), viewed in a cross-sectional plane perpendicular to a longitudinal axis, and a female connector comprising an internal polygonal profile (102), and wherein the external polygonal profile (90) of the male connector, viewed in a longitudinal axial section, is at least sectionally provided with convexly shaped flanks (92).

Abstract: The present disclosure relates to a self-aligning coupling linkage (32) for a drive train (28) of a hair cutting appliance (10) comprising a driving shaft (34) and a non-aligning output shaft (38), said coupling linkage (32) comprising a joint section (52) comprising a first connector portion (58, 158) and a second connector portion (60, 160) that are arranged to engage one another for torque transmission, wherein the first connector portion and the second connector portion define a male connector (58, 158) comprising an external polygonal profile (62, 162), viewed in a cross-sectional plane perpendicular to a longitudinal axis, and a female connector (60, 160) comprising an internal engagement profile (64, 164), wherein the male connector (58, 158) and the female connector (60, 160) are arranged in a self-aligning fashion for angular offset compensation, and wherein at least one of the male connector (58, 158) and the female connector (60, 160) is provided with at least one circumferentially arranged deflectable compensation element (100, 200) arranged to urge the male connector (58, 158) and the female connector (60, 160) towards a centered alignment. The disclosure further relates to a hair cutting appliance (10) that is equipped with such a coupling linkage (32).

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: There is disclosed a hair cutting device (10) comprising a cutting unit (30) having a guard (40) moveable relative a blade carrier (32) to vary a cutting length within a cutting length range. The cutting device (10) has an actuator (16) moveable between first and second positions to move a follower element (50) and the guard (40) between corresponding first and second positions to vary the cutting length between two extreme length settings. The cutting unit (30) is pivotable relative a housing unit (12) of the cutting device (10) between an open position and a closed position for cutting. The follower element (50) is configured to cooperate with the actuator (16) so that, when the cutting unit (30) is in the open position with the follower element (50) and guard (40) in the first position, but the actuator (16) is in the second position, pivoting movement of the cutting unit (30) to the closed position causes the actuator (16) to drive the follower element (50) and the guard (40) to the second position. Accordingly, the actuator (16) can engage with the follower element (50) when the cutting unit is in the closed position, despite the actuator and the follower element having non-corresponding positions when the cutting unit is in the open position.
