Abstract

The present invention relates to a hair cutting appliance (10) comprising a linkage unit (30) for a cutting unit (18), and to a linkage unit (30) for coupling a cutting unit (18) and a housing (12) of a hair cutting appliance (10). The linkage unit (30) comprises a four-bar linkage mechanism (32) comprising a first arm (42) and a second arm (44), the first arm (42) comprising a first base pivot (48) coupled to a base (38), the second arm (44) comprising a second base pivot (50) coupled to a base (38), the first base pivot (48) and the second base pivot (50) being arranged at the base (38) at a fixed distance, the first arm (42) further comprising a first top pivot (52) coupled to a connecting bar (46), the second arm (44) further comprising a second top pivot (54) coupled to the connecting bar (46), wherein the connecting bar (46) is arranged to be coupled to a cutting unit (18), such that, during operation, the cutting unit (18) is pivotably supported by the linkage mechanism (32). Preferably, at least one of the first base pivot (48) and the second base pivot (50) and the first top pivot (52) and the second top pivot (54) is arranged as a living hinge.

Description

technical field [0001] The present disclosure relates to hair cutting appliances, in particular to electrically operated hair cutting appliances and more particularly to a cutting unit and a linkage unit for coupling the cutting unit with a housing of the hair cutting appliance. The cutting unit may comprise a set of blades and may be arranged to move through the hair in the direction of movement to cut the hair. The blade set may include a fixed blade and a movable blade, wherein the movable blade is movable relative to the fixed blade so as to cut hair trapped therebetween. Background technique [0002] WO 2010 / 000352 A2 discloses an electric hair removal appliance comprising a handpiece extending in the direction of a central axis and provided with front and rear sides and with sides, and comprising a handpiece fastened to the handpiece via a holding device. An operating head having an operating unit comprising at least one operating element arranged to move via the oper...
