Abstract

The present invention relates to a beard trimmer having one or more rotary cutting heads (1), said rotary cutting heads having a moving blade (2) and a fixed blade (3), each head being surrounded by acrown-shaped comb (4), said comb being adjustable in height in order to adjust, in use, the distance between said blades and the skin, and thereby to adapt the cutting of the beard to the desired length, characterized in that the trimmer comprises a fixed blade having a shape characterised by: a tooth length L3 of 1 to 3 mm, preferably 1.5 to 2 mm; - an opening angle between the teeth of 20 to 30DEG, preferably 22 to 28DEG, and more preferably 24 and 27DEG;-a tooth width L2, at the end of the teeth, of 0.3 to 1 mm, preferably 0.4 to 0.9 mm.

Description

technical field [0001] The invention relates to a shaver comprising one or more rotating cutting heads with a vertical axis. The cutting mechanism of these rotating heads is equipped with a moving blade and a fixed blade. Each cutting head is surrounded by a height-adjustable crown comb. In use, the crown comb enables adjustment of the distance between the cutting mechanism and the skin, and thus the cut length of the beard. The razor according to the invention comprises a type of fixed blade with a specific geometry capable of adapting to any type of beard. Background technique [0002] Prior art razors currently have linearly moving blades and fixed blades, the operation of which is based on the back and forth movement of the moving blade relative to the fixed blade. This type of shaver is usually equipped with a comb that allows it to adjust the cut length of the beard. Such razors are for example disclosed in US D 698,084, US 6,978,547, US D 486,267, EP 2766153A1, US...
