Abstract

A hair clipping device including a housing; a cutting assembly arranged on one end of said housing including a stationary blade with a front edge and a moveable blade with a toothed edge arranged parallel to said front edge of the stationary blade, wherein the moveable blade is displaceably mounted on a surface of the stationary blade; a drive arrangement driving said moveable blade in an oscillatory movement in a transverse direction substantially parallel to the front edge of the stationary blade; an adjustment unit adjusting the position of the moveable blade with respect to the stationary blade in a first direction substantially perpendicular to said transverse direction; and a comb attachment releasably attached to the hair clipping device; wherein the adjustment unit adjusts the position of the comb attachment with respect to said cutting assembly in a second direction substantially perpendicular to said surface of the stationary blade.

First claim

The invention claimed is:

1. A hair clipping system with a hair clipping device that comprises:
a housing;
a cutting assembly arranged on one end of said housing and comprising a stationary blade with a front edge and a moveable blade with a toothed edge arranged parallel to said front edge of the stationary blade, wherein the stationary blade is fixedly mounted to the housing and the moveable blade is displaceably mounted on a surface of the stationary blade and resiliently biased against said surface of the stationary blade;
a drive arrangement configured to drive said moveable blade in an oscillatory movement in a transverse direction substantially parallel to the front edge of the stationary blade;
an adjustment unit configured to adjust a position of the moveable blade with respect to the stationary blade in a first adjustment direction substantially perpendicular to said transverse direction; and
a comb attachment with a plurality of comb teeth that can be releasably attached to the hair clipping device on a side of the stationary blade facing away from said surface of said stationary blade to create an adjustable gap between the comb teeth and said cutting assembly, that are adapted to at least partly surround the cutting assembly, and the moveable blade, the comb attachment being a separate part from the stationary blade;
wherein the adjustment unit is further configured to adjust a position of the comb attachment with respect to said cutting assembly in a second adjustment direction substantially perpendicular to said surface of the stationary blade when the comb attachment is attached to the hair clipping device,
wherein the comb attachment comprises a blocking element that is adapted to block the adjustment of the position of the moveable blade by the adjustment unit and to push the moveable blade to a predefined position along the first adjustment direction in response to the comb attachment being attached to the hair clipping device.

2. The hair clipping system according to claim 1 , wherein the adjustment unit comprises a releasable connection with the moveable blade, wherein the adjustment unit is configured to adjust the position of the moveable blade in the first adjustment direction through the releasable connection, which releasable connection is mechanically released by the blocking element of the comb attachment, thereby blocking the adjustment of the position of the moveable blade by the adjustment unit when the comb attachment is attached to the hair clipping device.

3. A hair clipping system with a hair clipping device that comprises:
a housing;
a cutting assembly arranged on one end of said housing and comprising a stationary blade with a front edge and a moveable blade with a toothed edge arranged parallel to said front edge of the stationary blade, wherein the stationary blade is fixedly mounted to the housing and the moveable blade is displaceably mounted on a surface of the stationary blade and resiliently biased against said surface of the stationary blade;
a drive arrangement configured to drive said moveable blade in an oscillatory movement in a transverse direction substantially parallel to the front edge of the stationary blade;
an adjustment unit configured to adjust a position of the moveable blade with respect to the stationary blade in a first adjustment direction substantially perpendicular to said transverse direction; and
a comb attachment with a plurality of comb teeth that can be releasably attached to the hair clipping device on a side of the stationary blade facing away from said surface of said stationary blade to create an adjustable gap between the comb teeth and said cutting assembly, that are adapted to at least partly surround the cutting assembly, and the moveable blade, the comb attachment being a separate part from the stationary blade;
wherein the adjustment unit is further configured to adjust a position of the comb attachment with respect to said cutting assembly in a second adjustment direction substantially perpendicular to said surface of the stationary blade when the comb attachment is attached to the hair clipping device,
wherein the adjustment unit comprises an adjustor handle that is arranged one of on and within the housing of the clipping device, which adjustor handle is rotatable around its central axis, wherein a rotational movement of the adjustor handle causes a movement of a slider to which the adjustor handle is connected, wherein the slider is linked to the moveable blade so as to activate a movement of the moveable blade in the first adjustment direction in response to the rotational movement of the adjustor handle, and wherein the slider is releasably connected to the comb attachment activating a movement of the comb attachment in the second adjustment direction in response to the rotational movement of the adjustor handle when the comb attachment is attached to the hair clipping device.

4. The hair clipping system according to claim 3 , wherein said adjustment unit comprises two independent adjustment elements, a first adjustment element configured to adjust the position of the moveable blade in said first adjustment direction, and a second adjustment element configured to adjust the position of said comb attachment in said second adjustment direction when the comb attachment is attached to the hair clipping device.

5. A hair clipping system with a hair clipping device that comprises:
a housing;
a cutting assembly arranged on one end of said housing and comprising a stationary blade with a front edge and a moveable blade with a toothed edge arranged parallel to said front edge of the stationary blade, wherein the stationary blade is fixedly mounted to the housing and the moveable blade is displaceably mounted on a surface of the stationary blade and resiliently biased against said surface of the stationary blade;
a drive arrangement configured to drive said moveable blade in an oscillatory movement in a transverse direction substantially parallel to the front edge of the stationary blade;
an adjustment unit configured to adjust a position of the moveable blade with respect to the stationary blade in a first adjustment direction substantially perpendicular to said transverse direction; and
a comb attachment with a plurality of comb teeth that can be releasably attached to the hair clipping device on a side of the stationary blade facing away from said surface of said stationary blade to create an adjustable gap between the comb teeth and said cutting assembly, that are adapted to at least partly surround the cutting assembly, and the moveable blade, the comb attachment being a separate part from the stationary blade;
wherein the adjustment unit is further configured to adjust a position of the comb attachment with respect to said cutting assembly in a second adjustment direction substantially perpendicular to said surface of the stationary blade when the comb attachment is attached to the hair clipping device,
wherein the adjustment unit comprises two independent adjustor handles that are arranged one of on and within the housing of the clipping device, which adjustor handles are rotatable around their common central axis, wherein a rotational movement of the first adjustor handle causes a movement of a first slider to which it is connected, wherein the first slider is linked to the moveable blade so as to activate a translational movement of the moveable blade in the first adjustment direction in response to the rotational movement of the first adjustor handle, and wherein a rotational movement of the second adjustor handle causes a movement of a second slider to which it is connected, wherein the second slider is connected to the comb attachment activating a movement of the comb attachment in the second adjustment direction in response
