A hair cutting appliance is configured to be moved through hair in a moving direction in order to cut hair. The hair cutting appliance includes a housing portion, a blade set having a skin-facing top surface, and a releasable attachment comb. The blade set is arranged pivotably with respect to the housing portion. The attachment comb includes a supporting frame, at least one spacing guard element configured to space the blade set from a working surface when in operation, a mounting portion configured to be attached to a housing portion of the hair cutting appliance, and an orientation determining portion configured to engage the blade set and to define a locking orientation of the blade set when mounted to the hair cutting appliance.

Attachment comb and hair cutting appliance

A hair-cutting appliance comprising at least 19 hair-cutting units (), each comprising a guard element () and a rotatably arranged hair-cutting element () having at least one hair-cutting edge (), is provided. The hair-cutting units of the hair-cutting appliance are relatively small, a base of the guard element having a diameter in a range of 7 mm to 13 mm. In order to have a relatively small guard element () which is of robust and uncomplicated design, and which is capable of contributing to excellent hair-cutting results without causing skin irritation, it is proposed to let both an inner surface () and an outer surface () of an annular shaving track () of the guard element () have a conical shape relative to a central axis () of the guard element (), in a similar slanting orientation relative to the central axis (), in at least a hair-cutting portion of the shaving track ().

Hair-cutting appliance comprising a guard element

A hair cutting appliance includes a stationary blade having a first wall portion arranged to serve as a skin facing wall when in operation; and a second wall portion offset from the first wall portion such that the first and second wall portions a guide slot that receives a movable cutter blade. A toothed leading edge is jointly formed by the first and second wall portions. Teeth at the toothed leading edge include a first leg defined by the first wall portion, and a second leg defined by the second wall portion. The first and second wall portions are connected at a frontal end of the toothed leading edge, thereby forming tips of the teeth. The second legs of the teeth are tapered along a portion of their longitudinal extension towards a bottom side of the stationary blade facing away from the skin, when in operation.

Stationary blade, blade set, and hair cutting appliance

A stationary blade for the blade set suitable for use with a hair cutting appliance that includes of wall segments fixedly interconnected forming a segmented stack, wherein an intermediate wall segment is disposed between a first wall segment and a second wall segment jointly forming, at an end of the segmented stack at least one toothed leading edge comprising a plurality of mutually spaced apart projections defining a plurality of teeth and respective tooth spaces, wherein the intermediate wall segment comprises a cutout and wherein the cutout in the intermediate wall segment, the first wall segment and the second wall segment define therebetween a guide slot for a movable blade.

Blade set, hair cutting appliance, and related manufacturing method

A hair cutting appliance, a blade set for a hair cutting appliance, and to a stationary blade for the blade set, the blade includes a first segment, a second segment, and an intermediate segment fixedly interconnected, forming a segmented stack, wherein the intermediate segment is disposed between the first segment and the second segment, jointly forming, at an end of the segmented stack, at least one toothed leading edge comprising a plurality of mutually spaced apart projections defining a plurality of teeth and respective tooth spaces wherein the intermediate segment comprises a cutout portion and wherein the cutout portion in the intermediate segment, the wall segment and the second segment define therebetween a guide slot for a movable blade.

A hair cutting appliance includes a blade set including a first wall portion and a second wall portion, each wall portion defining a first surface, a second surface, and at least one toothed leading edge including a plurality of mutually spaced apart projections provided with respective tips, wherein the first surfaces of the first wall portion and the second wall portion face each other, at least at their leading edges, wherein facing projections along the leading edges of the first and second wall portions are mutually connected at their tips to define a plurality of teeth, wherein the first surfaces of the first wall portion and the second wall portion define therebetween a guide slot for a movable blade and wherein the second surface of the first wall portion at, includes a smoothed transitional region, at least at the forwardly extending projections.

The present invention relates to a personal care device having a surface intended to engage the skin and/or hair, such as a blade razor or an electric shaver. The surface of such a device is formed from a substrate on which a hard coating layer is provided. A lubricating layer comprising pendant hydrophilic polymer chains is provided on the hard coating. The hard coating has particles incorporated therein, said particles having covalently attached thereto said pendant hydrophilic polymer chains. In addition, the present invention relates to a process of making a skin engaging surface for such personal care devices.

Personal care device with sliding surface

A stationary blade for a blade set of an electrically operated hair cutting appliance includes first and second walls, where each wall has a first surface, a second surface facing away from the first surface, and a laterally extending leading edge having a plurality of laterally spaced apart longitudinally extending projections. The first surfaces of the first and second walls face each other, at least at their leading edges, while corresponding projections along the leading edges of the first and second walls are mutually connected at their tips to define a plurality of generally U-shaped teeth. The first surfaces of the first and second walls are separated to define a laterally extending guide slot for insertion of a movable blade of the blade set between them. The projections of the first wall have an average thickness that is less than an average thickness of the projections of the second wall.
