Description

Object of the invention

The present invention relates to a beard trimmer having one or more rotary cutters with a vertical axis. The cutting mechanism of these rotating heads is equipped with a movable blade and a fixed blade. Each cutting head is surrounded by crown-shaped combs adjustable in height. In use, the combs make it possible to adjust the distance between the cutting mechanism and the skin and thus adjust the cut length of the beard. The cutting heads of the mower according to the invention are positioned in a mounted block tilting on a handle which allows, within certain limits, to automatically adapt the contact surface of the combs with the skin without changing the position of the handle.

State of the art

The beard mowers of the state of the art currently have linear moving and fixed blades whose operation is based on a movement back and forth of the movable blade relative to the fixed blade. This type of mower is generally equipped with a comb for adjusting the cutting length of the beard. Such beard trimmers are for example disclosed in US D 698084 , US 6978547 , US D 486267 , EP 2 766 153 A1 , US D 363809 , US 2013/0042487 , US 7076878 , US D 521683 ...

There are of course razors with multiple rotating heads that can shave very closely, they can not however used to trim a beard. Razors do not have combs to adjust the distance between the cutting mechanism and the skin. To our knowledge, however, there is no state of the art beard trimmer with rotating heads.

The mowers of the state of the art have a line of straight section at the intersection of movable teeth and fixed teeth. They have the disadvantage of trimming the hair differently depending on the direction of the mowing because the beard hair is most often inclined in one direction as they grow almost never perpendicular to the skin. Thus the mowing result with these mowers is very different depending on the direction of movement on the beard to cut.

The cutting heads surrounded by a ring-shaped comb and inserted in a tilting mounted block are not known from the state of the art.

Goals of the invention

The present invention aims to provide a beard trimmer with one or more rotary heads with vertical axis surrounded by crown-shaped combs and adjustable length to adjust the cutting height of the beard, the mower having a block in which are positioned cutting heads. The block is mounted tilting on the handle.

Summary of the invention

The present invention discloses a beard trimmer having a handle and a cutting system with one or more rotary cutting heads positioned on a block, said rotary cutting heads having a movable blade and a fixed blade, each head being surrounded by a comb in the form of a crown, said comb being adjustable in height and making it possible to adjust, in use, the distance between said blades and the skin and thus to adapt the cut of the hairs of the beard to the desired length, characterized in that the block comprising the cutting heads is mounted swinging on the handle.

Detailed description of the invention

Unlike beard trimmers of the state of the art, the mower according to the present invention has one or more circular rotary heads 1 vertical axis, surrounded by combs 4 in the form of a crown whose height is adjustable to half millimeter. This setting can be manual or motorized (not shown). This mower allows movement in arcs of circles on the beard just like a razor with rotating heads. This type of movement has the advantage to cut the size of the hair from all sides, regardless of the inclination of the latter relative to the skin, which results in a uniform size of the beard.

The movement of the combs 4 straightens the hairs that end up penetrating from the outside to the inside via the space left between two teeth in the waist area. The particular shape of the teeth of the comb 4, which gradually tapers towards the tip, allows easy penetration of the beard hair towards the cutting element composed of a fixed blade 3 and a movable blade 2.

The fixed blade 3 has radial notches, which also promotes the penetration of the hairs in the cutting mechanism.

The height of the telescopic combs 4 can be set approximately between 0 and 15 mm, preferably between 0 and 12 mm, and particularly preferably between 0 and 10 mm. The combs are almost completely retractable in the hood 6 to take up less space when storing the mower.

The cutting heads 1 are positioned on a block 8 pivotally mounted on the handle 7. The point of contact between the handle 7 and the block 8 consists of a fulcrum allowing tilting in all directions. The fulcrum 9 can take many forms such as a spherical sphere or a ball joint mounted on a spring. The tilting of this block 8 in all directions from about 20 ° to 30 ° allows improved adaptation to the angle of the face approached by the mower.

The block 8 with the cutting heads 1 also comprises a return means to its equilibrium position such as a spring for example.

Block 8 can also be equipped with a damping system allowing a softer contact with the skin.

The height adjustment of the combs 4 is performed by a knob 6 located on the block 8. The cover 5 has a free space below the knob 6 to allow the removal thereof for rinsing with water.
