Abstract: A cutting set for a hair clipper, includes a first stationary cutting blade with a comb, a second cutting blade with a comb which is movable in a lateral direction towards the stationary cutting blade, and a connecting device which presses the second cutting blade against the first cutting blade, wherein behind the comb of the stationary cutting blade there is provided a dust groove, which runs over the entire width of the stationary cutting blade as far as both lateral ends, and wherein the dust groove increases in the direction of at least one lateral end in a height direction.

Abstract: The invention relates to a hair-cutting device (100) comprising: a housing; a blade assembly for cutting hair; a motor (130) for driving the blade assembly, which motor is located in the housing; a receiving space (140) for at least partially receiving a rechargeable battery, the receiving space (140) being located in the housing and having, in the longitudinal direction (170), at least one bottom and, on the periphery, one wall or multiple walls which delimit the receiving space (140); and a plug connection (160) for plugging in the rechargeable battery, the plug connection (160) being electrically connected to the motor (130).

Abstract: Adjustment device (10) for a hair cutting device (20), the hair cutting device (20) having a device housing (22) and a cutting set (24) connected to the device housing (22), the cutting set (24) of a shear blade (26), which contains shear blade tips (30), and a shaving comb (28) connected therewith, which contains comb tips (32), wherein the shaving comb (28) is connected to the shear blade (26) and thus also releasably connectable to the hair cutting device (20). The adjustment device (10) is dimensioned in such a way that it can receive and hold the shaving comb (28) so that after loosening the connecting elements (62), the shaving comb (28) together with the adjustment device (10) is movable relative to the device housing (22) so that a distance between the shear blade tips (30) and the comb tips (32) can be set.

Abstract: Blade arrangement for a hair clipper comprising a comb with an anterior edge, which contains tooth elements; a blade with an anterior cutting edge, which contains tooth elements, wherein the cutting edge at its anterior end is downwardly sloped towards the lower cutting edge, and wherein the blade is configured to be movable relative to the comb; a connecting device, which connects the comb and the blade relatively movable to each other; and a pretension element, which preloads the comb and the blade against each other characterized in, that the cutting edge of the blade have a wave shape, wherein the anterior cutting edge of the blade contains at least three tooth elements and/or the edges of each tooth element have a curved shape according to the wave shape.
