摘要： A hair cutter comprising a cover plate displaceably disposed relative to and opposite a blade carrier plate, the cover plate having a row of teeth covering a blade cutting edge. Downwardly pointing teeth-like arresting projections are mounted on a flanged downwardly facing part of the blade carrier plate and positively engage upwardly pointing arresting teeth on lateral shoulders of a push button actuating element, the latter disposed perpendicular to the plane of the blade. The arresting projections are biased into an arresting position and are releasable by a push button actuating element which slidably projects through a complementary opening formed in the cover plate, whereby the arresting teeth of the shoulders being released from the downwardly pointing and complementary arresting teeth upon pushing the push button actuating element downwardly.

摘要： A hair cutter comprising a blade interchangeably retained between a blade-supporting plate and a cover plate, the latter having a row of teeth which overlaps said blade cutting edge. The plates are displaceable perpendicularly to the blade cutting edge and relatively to one another between two end positions, and the blade-supporting plate bears the blade as far as adjacent the cutting edge, yet leaving the blade cutting edge exposed. In a zone adjoining the blade cutting edge, the blade-supporting plate has at least in part a wedge-shaped portion increasing in thickness extending from the blade cutting edge in a rearward direction, so that when the hair cutter is placed on the head of the user the blade is adjustable to a cutting angle determined by front ends of the teeth and application portions of the wedge-shaped portion on the user's head. A coupling member is disposed on each of the two plates for locating the plates with respect to one another in selectable displacement positions and a spring retains the coupling members with prestressing in positive engagement with one another, an actuating element extending through one of the two plates and being accessible from an outside, and movably retained perpendicularly to the plane of the blade, and engaging with one of the coupling members and disengaging the latter on actuation against the spring.
