Abstract

The present invention relates to a hair clipping device (10) comprising: a housing (14), a cutting assembly (16) which is arranged on a distal end (18) of said housing (14) and comprises a stationary cutting blade (22) with a stationary cutting edge (26) and a moveable cutting blade (24) with a moveable cutting edge (28), and a comb attachment (12) which is attachable to the housing (14) and comprises a first comb element (34) and a second comb element (38); wherein the first comb element (34) is configured to be arranged on a front side (36) of the housing (14) and configured to cover the stationary and the moveable cutting edge (26, 28), wherein said front side (36) runs transverse to the distal end (18) and the cutting assembly (16), and wherein the first comb element (36) comprises a plurality of first comb ribs (40) running parallel to each other and parallel to a first longitudinal direction (44) of the first comb element (34); wherein the second comb element (38) is arranged transverse to the first comb element (34) and configured to at least partly cover the distal end (18) of the housing (14), wherein the second comb element (38) comprises a plurality of second comb ribs (42) running parallel to each other and parallel to a second longitudinal direction (46) of the second comb element (38), wherein a gap size (48), which is defined as distance between two of the second comb ribs (42) measured in lateral direction (50) perpendicular to the second longitudinal direction (46), is smaller than 1 mm and wherein the second comb element (38) comprises a connection beam (68) that is arranged at a back end (58) of the second comb ribs (42) opposite their free end (60) and runs parallel to the lateral direction (50); and wherein a free end (64) of the first comb ribs (40) is spaced apart from a free end (60) of the second comb ribs (42), such that a gap (66) occurs between the first and the second comb element (34, 38).

First claim

The invention claimed is:

1. A hair clipping device comprising:
a housing,
a cutting assembly which is arranged on a distal end of said housing and comprises a stationary cutting blade with a stationary cutting edge and a moveable cutting blade with a moveable cutting edge, and
a comb attachment which is attachable to the housing and comprises a first comb element having a plurality of first comb ribs and a second comb element having a plurality of second comb ribs;
wherein the first comb element is configured to be arranged on a front side of the housing and configured to cover the stationary and the moveable cutting edge, wherein said front side runs transverse to the distal end and the cutting assembly, and wherein the plurality of first comb ribs run parallel to each other and parallel to a first longitudinal direction of the first comb element;
wherein the plurality of second comb ribs are arranged transverse to the plurality of first comb ribs and are configured to at least partly cover the distal end of the housing, wherein the plurality of second comb ribs run parallel to each other and parallel to a second longitudinal direction of the second comb element, wherein a gap size, which is defined as distance between two of the second comb ribs measured in lateral direction perpendicular to the second longitudinal direction, is smaller than 1 mm, and wherein the second comb element comprises a connection beam that is arranged at a back end of the second comb ribs opposite their free end and runs parallel to the lateral direction; and
wherein a free end of the first comb ribs is spaced apart from a free end of the second comb ribs, such that a gap occurs between the first and the second comb element.

2. The hair clipping device according to claim 1 , wherein a backside of the connection beam that faces away from the distal end is configured to touch a skin of the user during use, and wherein said backside is arranged substantially coplanar with a corresponding backside of the second comb ribs.

3. The hair clipping device according to claim 1 , wherein a height of the second comb ribs measured perpendicular to the lateral and the second longitudinal direction is at the free end of the second comb ribs smaller than 2 mm.

4. The hair clipping device according to claim 1 , a height of the second comb ribs measured perpendicular to the lateral and the second longitudinal direction is at the back end of the second comb ribs larger than 1 mm and smaller than 5 mm.

5. The hair clipping device according to claim 1 , wherein the free end of the second comb ribs comprises a rounded tip portion.

6. The hair clipping device according to claim 1 , wherein a pitch size, which is defined as a sum of the gap size and a width of one of the second comb ribs measured in the lateral direction, is smaller than 2 mm.

7. The hair clipping device according to claim 6 , wherein the pitch size of the second comb ribs is larger than 0.7 mm and smaller than 1.7 mm.

8. The hair clipping device according to claim 1 , wherein the gap size of the second comb ribs is larger than 0.2 mm and smaller than 0.8 mm.

9. The hair clipping device according to claim 1 , wherein a width of the second comb ribs is larger than 0.5 mm and smaller than 1 mm.

10. The hair clipping device according to claim 1 , wherein a length of the second comb ribs measured along the second longitudinal direction is smaller than or equal to 20 mm.

11. The hair clipping device according to claim 1 , further comprising an adjustment mechanism for adjusting the position of the comb attachment relative to the cutting assembly.

12. The hair clipping device according to claim 1 , wherein an angle between the first longitudinal direction of the first comb element and the second longitudinal direction of the second comb element is smaller than 90°, preferably smaller than 80°.

13. The hair clipping device according to claim 1 , further comprising a suction unit for generating an under-pressure in an area between the cutting assembly and the comb attachment.

14. A comb attachment for attachment to a hair clipping device having a housing and a cutting assembly which is arranged on a distal end of said housing and comprises a stationary cutting blade with a stationary cutting edge and a moveable cutting blade with a moveable cutting edge,
wherein the comb attachment comprises a first comb element having a plurality of first comb ribs and a second comb element having a plurality of second comb ribs;
wherein the first comb element is configured to be arranged on a front side of the housing and configured to cover the stationary and the moveable cutting edge, wherein said front side runs transverse to the distal end and the cutting assembly, and wherein the plurality of first comb ribs run parallel to each other and parallel to a first longitudinal direction of the first comb element;
wherein the plurality of second comb ribs are arranged transverse to the plurality of first comb ribs and are configured to at least partly cover the distal end of the housing, wherein the plurality of second comb ribs run parallel to each other and parallel to a second longitudinal direction of the second comb element, wherein a gap size, which is defined as distance between two of the second comb ribs measured in lateral direction perpendicular to the second longitudinal direction, is smaller than 1 mm and wherein the second comb element comprises a connection beam that is arranged at a back end of the second comb ribs opposite their free end and runs parallel to the lateral direction; and
wherein a free end of the first comb ribs is spaced apart from a free end of the second comb ribs, such that a gap occurs between the first and the second comb element.
