Hair trimming device
A manually operated hair trimming device having a barrel which is rolled over hair to be trimmed. The barrel has at least one aperture through which hair is able to protrude. The device has a first cutting blade provided inside the barrel and a second cutting blade is associated with the barrel. In use, as the barrel is rolled over hair to be trimmed, hair protrudes through the at least one aperture and is cut by a shearing force between relatively moving first and second cutting blades.
1. A manually operable hair trimming device comprises:
a barrel which is rolled over hair to be trimmed, the barrel has at least one aperture;
a first cutting blade provided inside the barrel;
a second cutting blade associated with the barrel; and
a guide comprising raised parts arranged to space an outer contact surface of the barrel from a user's skin;
whereby in use, as the barrel is rolled over the hair to be trimmed, hair protrudes through the at least one aperture and is cut at a cutting point by a shearing force between relative movement of the first cutting blade and the second cutting blade;
wherein at least part of the barrel has a comb that overhangs the second cutting blade so as to direct hair and space the cutting point from the user's skin.
2. The manually operable hair trimming device according to claim 1 wherein an edge of the at least one aperture on the barrel defines the second cutting blade.
3. The manually operable hair trimming device according to claim 1 wherein the second cutting blade is arranged on an inner face of the barrel.
4. The manually operable hair trimming device according to claim 1 wherein the comb is provided on an edge of the at least one aperture, the comb being circumferentially offset from the second cutting blade so that the comb directs hair to the cutting point.
5. The manually operable hair trimming device according to claim 1 wherein an outer surface of the barrel is spaced radially from the cutting point by at least 1 mm.
6. The manually operable hair trimming device according to claim 1 wherein the raised parts are nodes that are resiliently deformable.
7. The manually operable hair trimming device according to claim 1 wherein the first cutting blade and the second cutting blade are shaped and tapered in opposite directions so as to define scissoring edges.
8. The manually operable hair trimming device according to claim 1 wherein the first cutting blade and the second cutting blade are formed from stainless steel.
9. The manually operable hair trimming device according to claim 1 further comprising at least one end cap.
10. The manually operable hair trimming device according to claim 9 wherein the at least one end cap is removable so as to enable removal of cut hair.
11. A manually operable hair trimming device comprises:
a barrel with at least one aperture through which hair to be trimmed protrudes;
a first cutting blade provided inside the barrel;
a second cutting blade associated with the barrel; and
a guide comprising raised parts arranged to space an outer contact surface of the barrel from a user's skin;
whereby in use, as the device is rolled over the hair to be trimmed, hair protrudes through the at least one aperture and is cut at a cutting point by a shearing force between relative movement of the first cutting blade and the second cutting blade;
wherein at least part of the barrel has a comb that overhangs the second cutting blade so as to direct hair and space the cutting point from the user's skin.
12. A manually operable hair trimming device comprising:
a barrel which is rolled over hair to be trimmed, the barrel has at least one aperture;
a first cutting blade provided inside the barrel;
a second cutting blade associated with the barrel; and
a sleeve fitted over the barrel,
whereby in use, as the barrel and the sleeve are rolled in unison over the hair to be trimmed, hair protrudes through the at least one aperture and is cut at a cutting point by a shearing force between relative movement of the first cutting blade and the second cutting blade;
wherein at least part of the barrel has a comb that overhangs the second cutting blade so as to direct hair and space the cutting point from a user's skin.
13. The manually operable hair trimming device according to claim 12 further comprising a cover which has at least one opening formed therein through which a protruding part of the sleeve protrudes.
14. The manually operable hair trimming device according to claim 13 wherein edges of at least one aperture in the cover are tooth or scallop shaped.
