A hair cutting appliance including 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 includes a smoothed transitional region at least at the forwardly extending projections.

Blade set and hair cutting appliance

The present invention relates to a hair cutting appliance (), a blade set () for a hair cutting appliance (), and to a stationary blade () for said blade set (), said blade comprising a first wall portion () and a second wall portion (), each which defining a first surface (), and a second surface () facing away from the first surface (), and an intermediate wall portion () arranged between the first and the second wall portion (), wherein the first wall portion () the second wall portion () and the intermediate wall portion () jointly define at least one toothed leading edge (), wherein the first surfaces () of the first wall portion () and the second wall portion () face each other, at least at their leading edges (), the first wall portion (), the second wall portion () and the intermediate wall portion () are interconnected 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 () of said blade set (), wherein the first wall portion (), the second wall portion () and the intermediate wall portion () comprise an overall height extension (to), and wherein the overall height extension (to) of the first wall portion (), the second wall portion () and the intermediate wall portion (), at least at the at least one leading edge (), is in the range of about 0.3 mm to about 0.75 mm, preferably in the range of about 0.4 mm to 0.5 mm.

The present invention relates to a hair cutting appliance () and a blade set () for a hair cutting appliance (), said blade set () being arranged to be moved through hair in a moving direction () to cut hair, said blade set () comprising a stationary blade (), comprising 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 () comprising a plurality of mutually spaced apart projections (), wherein the toothed leading edge () at least partially extends in a transverse direction (Y, t) relative to the moving direction (), wherein the mutually spaced apart projections () at least partially extend forwardly in a longitudinal direction (X, r) approximately perpendicular to the transverse direction (Y, t), wherein the first surfaces () of the first wall portion () and the second wall portion () face each other, at least at their leading edges (), wherein, in a filled region (), 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 (), a movable blade () comprising at least one toothed leading edge (), said movable blade () being movably arranged within a guide slot () defined by the stationary blade (), wherein the guide slot (), at least partially extends into the forwardly extending projections () to an inwardly facing end face () of the filled region (), and wherein the toothed leading edge () of the movable blade () is spaced apart from the end face () of the filled region (), thereby defining a clearance portion (), and wherein the movable blade () leading edge () and the end face () are longitudinally spaced apart by a clearance longitudinal dimension (l) of less than 0.5 mm, preferably less than 0.2 mm, more preferably less than 0.1 mm.
