Abstract
The invention relates to a comb (100) for being attached to a hair-cutting device (115). The comb comprises two surfaces (103, 104) configured to be in contact with the skin of the user. Each surface comprises a slot (105, 106) for attaching the comb to the hair-cutting device, and both surfaces have a common edge (107). When the hair-cutting device is attached to the slot of the first surface, the second surface is in contact with the skin, and when the hair-cutting device is attached to the slot of the second surface, the first surface is in contact with the skin. An asymmetric arrangement of the two slots allows for two cutting lengths of hair with one double-sided comb.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0043] FIG. 1 shows a schematic set-up of a first exemplary embodiment of a comb 100 in a first attachment position 101 including a hair-cutting device 115. The comb 100 is with the first surface 103, which is shown as bottom surface, in contact with the skin 117 of the user. The second surface 104, in this figure the top surface, has a common edge 107 with the first surface 103. The second surface comprises a second slot 106, which receives the cutting element 116 of the hair-cutting device 115, as the comb 100 is attached to the hair-cutting device 115 in this first attachment position 101. The first slot 105 at the first surface 103, which is in contact with the skin 117, is not used in this first attachment position 101. In this exemplary embodiment of the invention, the first distance 108 of the first slot 105 from the common edge 107 is smaller than the second distance 109 of the second slot 106 from the common edge 107. The first length 110 of the first surface 103 and the second length 111 of the second surface 104 are identical in this first exemplary embodiment. In addition, the first depth 112 of the first slot 105 and the second depth 113 of the second slot 106 are depicted with identical size.
[0044] FIG. 2 shows a schematic set-up of the first exemplary embodiment of a comb 100 in a second attachment position 102 including a hair-cutting device 115. Compared to the first attachment position 101 as shown in FIG. 1, the comb 100 is in the second attachment position 102 rotated around the virtual axis 114 by 180 degrees. The virtual axis 114 cuts with the common edge 107 and is part of the angle-bisecting plane of the first surface 103 and of the second surface 104. The rotation leads to an interchange of the first surface 103 and the second surface 104. In this second attachment position 102, the comb 100 is attached to the hair-cutting device 115 in a manner, that the cutting element 116 is receive by the first slot 105. The second slot 106 is not used in this second attachment position 102. The second surface 104 is in contact with the skin 117 of the user.
[0045] FIGS. 3a and 3b show a comparison of a schematic set-up of the first exemplary embodiment of a comb 100 in the first attachment position 101 in FIG. 3a and in the second attachment position 102 in FIG. 3b. The comb 100 is positioned in between of the hair-cutting device 115 and the skin 117 of the user. In the first attachment position 101, the first cutting length 119 of hair is defined as the distance of the cutting element 116 from the skin 117. In the second attachment position 102, the second cutting length 120 of hair is defined as the distance from the cutting element 116 from the skin 117. As can be seen, in this first exemplary embodiment, the first cutting length 119 is larger than the second cutting length 120.
[0046] FIGS. 4a and 4b show a comparison of a schematic set-up of a second exemplary embodiment of a comb 400 in a first attachment position 401 in FIG. 4a and in a second attachment position 402 in FIG. 4b. The comb 400 is positioned in between of the hair-cutting device 115 and the skin 117 of the user. In this second exemplary embodiment of the invention, the distances of the first slot 405 to the common edge and of the second slot 406 to the common edge are identical. However, the depth of the second slot 406, which receives the cutting element 116 in the first attachment position 401, is smaller than the depth of the first slot 405, which is not used in this first attachment position 401. The first surface 403 is in contact with the skin 117. In the second attachment position 402 as shown in FIG. 4b, the first slot 405 receives the cutting element 116 and the second surface 404 is in contact with the skin 117. The different depths of the first slot 405 and of the second slot 406 result in different cutting lengths. In the first attachment position 401, the first cutting length 419 of hair is defined as the distance of the cutting element 116 from the skin 117. In the second attachment position 402, the second cutting length 420 of hair is defined as the distance from the cutting element 116 from the skin 117. In this second exemplary embodiment, the first cutting length 419 is larger than the second cutting length 420.
[0047] FIGS. 5a and 5b show a comparison of a schematic set-up of a third exemplary embodiment of a comb 500 in a first attachment position 501 in FIG. 5a and in a second attachment position 502 in FIG. 5b. The comb 500 is positioned in between of the hair-cutting device 115 and the skin 117 of the user. In this third exemplary embodiment of the invention, the first surface 503 and the second surface 504 are parallel to each other. The depth of the second slot 506, which receives the cutting element 116 in the first attachment position 501, is smaller than the depth of the first slot 505, which is not used in this first attachment position 501. The first surface 503 is in contact with the skin 117. In the second attachment position 502 as shown in FIG. 5b, the first slot 505 receives the cutting element 116 and the second surface 504 is in contact with the skin 117. The different depths of the first slot 505 and of the second slot 506 result in different cutting lengths. In the first attachment position 501, the first cutting length 519 of hair is defined as the distance of the cutting element 116 from the skin 117. In the second attachment position 502, the second cutting length 520 of hair is defined as the distance from the cutting element 116 from the skin 117. In this third exemplary embodiment, the first cutting length 519 is larger than the second cutting length 520.
[0048] FIGS. 6a and 6b show a comparison of a schematic set-up of the first exemplary embodiment of a comb 100 in the first attachment position 101 in FIG. 6a and in the second attachment position 102 in FIG. 6b including a hair-cutting device 115 with an illustration of the different cutting lengths of hair 118. The comb 100 is positioned in between of the hair-cutting device 115 and the skin 117 of the user. The distance of the cutting element 116 from the skin 117 defines the cutting length of hair the hair 118. The first cutting length 119 in the first attachment position 101 shown in FIG. 6a is larger than the second cutting length 120 in the second attachment position 102 shown in FIG. 6b.
