Abstract: The present invention relates to a hair clipping device (10) which comprises a housing (14), a cutting assembly (16) including a stationary cutting blade (32) and a moveable cutting blade (34), a drive arrangement (42) for driving the moveable cutting blade (34) relative to the stationary cutting blade (32) in an oscillatory movement along a first axis (40), a comb support element (45) for removably attaching a comb attachment (12) with a plurality of comb teeth (50), and an adjustment unit (58) for adjusting the position of the comb attachment (12) relative to the cutting assembly (16), when the comb attachment (12) is attached to the comb support element (45), wherein the adjustment unit (58) is configured to increase a distance between the comb attachment (12) and the cutting assembly (16) during an extension movement of the adjustment unit (58), and to decrease the distance between the comb attachment (12) and the cutting assembly (16) during a retraction movement of the adjustment unit (58). The hair clipping device (10) further comprises an end stop element (74) which is configured to prevent a movement of the comb attachment (12) towards the cutting assembly (16) during the retraction movement when a minimal distance between the comb attachment (12) and the cutting assembly (16) is reached by contacting the comb support element (45). The end stop element (74) is further configured to cause a coupling of the adjustment unit (58) with one of the stationary cutting blade (32) and the moveable cutting blade (34) if the retraction movement of the adjustment unit (58) is continued after the minimal distance between the comb attachment (12) and the cutting assembly (16) is reached after a contact of the end stop element (74) with the comb support element (45). Said coupling enables an adjustment of the position of the moveable cutting blade (34) relative to the stationary cutting blade (32) along a second axis (56) transverse to the first axis (40) by means of the adjustment unit (58).

Abstract: An adjustment drive for an adjustable spacing comb for a hair cutting appliance includes an actuator configured to actuate a movable comb portion of the adjustable spacing comb with respect to a blade set of the hair cutting appliance, and a drivetrain for coupling the actuator and the movable comb portion. The drivetrain includes a reduction gear unit and a location detection unit having a rotary encoder which is coupled to an output shaft of the reduction gear 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.
