Abstract

The invention relates to a comb (100) for being attached to a hair-cutting device (115). The comb includes two surfaces (103, 104) to be in contact with the skin of the user. Each surface includes 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.

First claim

The invention claimed is:

1. A comb for being attached to a hair-cutting device, the comb comprising:
a first surface configured to be in contact with a skin of a user when the comb is attached to the hair-cutting device in a first attachment position,
wherein the first surface comprises a first slot configured to receive a cutting element of the hair-cutting device when the comb is attached to the hair-cutting device in a second attachment position,
a second surface configured to be in contact with the skin of the user when the comb is attached to the hair-cutting device in the second attachment position, and
wherein the second surface comprises a second slot configured to receive the cutting element of the hair-cutting device when the comb is attached to the hair-cutting device in the first attachment position.

2. The comb according to claim 1 ,
wherein the first surface and the second surface extend to define common edge, and
wherein the common edge forms a tip of the comb.

3. The comb according to claim 2 ,
wherein the first slot is positioned in the first surface of the comb with a first distance from the common edge,
wherein the second slot is positioned in the second surface of the comb with a second distance from the common edge, and
wherein the first distance is different from the second distance.

4. The comb according to claim 1 ,
wherein the first slot has a first depth with respect to the first surface,
wherein the second slot has a second depth with respect to the second surface, and
wherein the first depth is equal to the second depth.

5. The comb according to claim 1 ,
wherein the first slot has a first depth with respect to the first surface,
wherein the second slot has a second depth with respect to the second surface, and
wherein the first depth is different from the second depth.

6. The comb according to claim 1 ,
wherein the comb has a wedge shape.

7. The comb according to claim 1 ,
wherein the first surface is parallel to the second surface.

8. The comb according to claim 1 ,
wherein the comb is configured when being attached in the first attachment position to the hair-cutting device to cause a first cutting length of hair,
wherein the comb is configured when being attached in the second attachment position to the hair-cutting device to cause a second cutting length of hair,
wherein the first cutting length of hair is different from the second cutting length of hair.

9. A hair-cutting device comprising a comb according to claim 1 .

10. The hair-cutting device according to claim 9 ,
wherein the hair-cutting device is a shaver, a trimmer or a groomer.

11. A method of adapting a cutting length of a hair-cutting device with a comb according to claim 1 , the method comprising the steps:
detaching the comb from the hair-cutting device,
rotating the comb around a virtual axis of the comb, and
attaching the comb to the hair-cutting device.

12. The method according to claim 11 ,
wherein rotating the comb is carried out by rotating the comb around a virtual axis that is part of an angle-bisecting plane of the first surface and of the second surface in order to interchange the first attachment position and the second attachment position.
