A blade set for a hair cutting appliance includes a stationary blade and a cutter blade. The stationary blade has a blade base and a plurality of teeth extending from the blade base in a longitudinal direction. The teeth are arranged in a series alternating with tooth gaps therebetween, where the tooth gaps define hair entry slots. The teeth have a first side arranged to cooperate with the cutter blade to cut hair and a second side arranged as a skin-facing side. The teeth have processing edges at the first side at their longitudinal extension, where the smoothened processing edges have smoothened edge transitions.

Blade set and hair cutting appliance

A cutting unit having a blade carrier carrying a cutting blade, and a guard. The guard includes a blade-facing surface engaging the cutting blade at a cut location, a planar guard contact surface for contacting the user's skin, where the guard contact surface is angled with respect to the blade-facing surface, and a guard extender separate from the guard. The guard extender includes a planar extension contact surface cooperating with the guard contact surface to provide an extended contact zone across the guard and the guard extender for contacting a user's skin. The blade-facing surface and the guard contact surface converge towards a tip of the guard, such that a cutting direction extends along the guard contact surface towards the tip. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.

Cutting unit

A hair cutting device having a cutting unit, the cutting unit including a blade carrier carrying a cutting blade that has cutting teeth; a guard blade that has guard teeth. The blade is movable along the blade carrier relative to the cutting blade within a guard length range between a first guard position corresponding to a shortest hair cutting length of the cutting unit and a second guard position corresponding to the longest hair cutting length of the cutting unit. The blade carrier includes a stop configured to prevent movement of the guard blade past the first guard position and outside of the guard length range, thereby preventing the cutting length from being below the shortest cutting length.

Hair cutting device

A blade set for a hair cutting appliance includes a stationary blade and a cutter blade. The stationary blade has a blade base and a plurality of teeth extending from the blade base in a longitudinal direction. The teeth are arranged in a series alternating with tooth gaps therebetween, where the tooth gaps define hair entry slots. The teeth have a first side arranged to cooperate with the cutter blade to cut hair and a second side arranged as a skin-facing side. The teeth have processing edges at the first side at their longitudinal extension, where the processing edges have smoothened edge transitions.

There is disclosed a cutting unit () for a hair cutting device (), comprising: a blade carrier () carrying a cutting blade; a guard () comprising: a blade-facing surface engaging the cutting blade at a cut location; a planar guard contact surface () for contacting skin of a user, wherein the guard contact surface () is angled with respect to the blade-facing surface; and a guard extender () separate from the guard (), wherein the guard extender () comprises a planar extension contact surface () configured to cooperate with the guard contact surface () to provide an extended contact zone () across the guard () and the guard extender () for contacting skin of a user. The blade-facing surface and the guard contact surface () converge towards a tip of the guard, wherein a cutting direction extends along the guard contact surface () towards the tip. The guard extender () is configured so that the extension contact surface () is rearward of the guard contact surface () with respect to the cutting direction X. The extension contact surface () has a transverse extent along an axis perpendicular to the cutting direction, and wherein there is a gap along the cutting direction X between the guard contact surface and at least a transverse portion of the extension contact surface. The extended contact zone may provide for improved stability and reliable orientation of the cutting unit for cutting while limiting material use.

A hair cutting device includes a cutter having a guard moveable relative a blade carrier to vary a cutting length within a cutting length range. The cutter has an actuator moveable between first and second positions to move a follower element and the guard to vary the cutting length between two extreme length settings. The cutter is pivotable relative a housing of the cutting device between an open position and a closed position for cutting. The follower element is configured to cooperate with the actuator so that, when the cutter is in the open position with the follower element and guard in the first position, but the actuator is in the second position, pivoting movement of the cutter to the closed position causes the actuator to drive the follower element and the guard to the second position.

The present invention relates to a hair clipping device () comprising: a housing (), a cutting assembly () which is arranged on a distal end () of said housing () and comprises a stationary cutting blade () with a stationary cutting edge () and a moveable cutting blade () with a moveable cutting edge (), and a comb attachment () which is attachable to the housing () and comprises a first comb element () and a second comb element (); wherein the first comb element () is configured to be arranged on a front side () of the housing () and configured to cover the stationary and the moveable cutting edge (), wherein said front side () runs transverse to the distal end () and the cutting assembly (), and wherein the first comb element () comprises a plurality of first comb ribs () running parallel to each other and parallel to a first longitudinal direction () of the first comb element (); wherein the second comb element () is arranged transverse to the first comb element () and configured to at least partly cover the distal end () of the housing (), wherein the second comb element () comprises a plurality of second comb ribs () running parallel to each other and parallel to a second longitudinal direction () of the second comb element (), wherein a gap size (), which is defined as distance between two of the second comb ribs () measured in lateral direction () perpendicular to the second longitudinal direction (), is smaller thanmm and wherein the second comb element () comprises a connection beam () that is arranged at a back end () of the second comb ribs () opposite their free end () and runs parallel to the lateral direction (); and wherein a free end () of the first comb ribs () is spaced apart from a free end () of the second comb ribs (), such that a gap () occurs between the first and the second comb element ().

Hair clipping device

A hair clipping device includes a housing, and a cutting assembly which is arranged on a distal end of the housing and which includes a stationary cutting blade and a moveable cutting blade. The hair clipping device includes further includes a comb attachment which is releasably attachable to the housing and includes a plurality of comb teeth. A front side of the housing that runs transverse to the distal end and the cutting assembly includes a corrugated surface with a plurality of adjacent ribs and recesses running parallel to each other. The backside of the comb teeth contacts the corrugated surface when the comb attachment is attached to the housing.
