Abstract

A blade arrangement for a hair clipper comprises a comb with an anterior edge, which contains tooth elements; a blade with an anterior cutting edge, which contains tooth elements, with the anterior cutting edge being downwardly sloped towards the lower cutting edge, and the blade being 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. The device is characterized in that the cutting edge of the blade has a wave shape, 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.

Description

technical field [0001] The present invention relates to a trimmer for a hair clipper with corrugated cutting edges. Background technique [0002] In the prior art, various hair clippers with different blade sets are known. For example, US Pat. No. 7,841,901 B2 discloses a blade set for a hair clipper comprising at least one fixed blade with a plurality of fixed blade teeth and at least one movable blade with a plurality of fixed blade teeth, The blades are configured to reciprocate laterally relative to at least one stationary blade to trim hair. The movable blade includes a set of long teeth configured to trim hair across the width of the movable blade and a set of short teeth configured to cut hair across the width of the movable blade when the hair clipper is advanced above a specified speed. Trim the hair in the upward direction. [0003] US Pat. No. 5,933,953 discloses a hair clipper for trimming strands of hair having a blade set having a fixed blade with a pluralit...
