Abstract
Razor having a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member. Each sawing tooth has a tooth tip and tooth edges mutually connected via the tooth tip. The hair-severing member is mounted for sawing through hairs present on the skin by means of the sawing teeth by moving each sawing tooth in a local direction of extension of the hair-severing edge at the position of the respective sawing tooth. A drive is coupled to the hair-severing member for driving the hair-severing member such that the sawing teeth move with an average velocity larger than or equal to 10 m/s. The spacing between the tooth tips of two successive sawing teeth is between 20 μm and 150 μm.
Claims16
A razor comprising:
- a support;
- a skin engagement surface;
- a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member, each sawing tooth of the plurality of sawing teeth having a tooth tip and tooth edges mutually connected via the tooth tip, wherein a spacing between tooth tips of two successive sawing teeth is between 20 μm and 150 μm;
- wherein the hair-severing member:
- is mounted to the support in a position relative to the skin engagement surface such that the hair-severing edge is exposed to skin of a user for sawing through hairs present on the skin by means of the sawing teeth when the skin engagement surface is in contact with the skin, and
- is suspended relative to the support for allowing movement of each sawing tooth in a respective local direction of extension of the hair-severing edge at a position of the sawing tooth;
- and
- a drive coupled to the hair-severing member for driving the hair-severing member relative to the support such that each sawing tooth moves in the respective local direction of extension of the hair-severing edge with an average velocity larger than or equal to 10 m/s.
A method of shaving hairs projecting from a skin surface, the method comprising:
- providing a razor comprising:
- a support;
- a skin engagement surface;
- a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member, each sawing tooth of the plurality of sawing teeth having a tooth tip and tooth edges mutually connected via the tooth tip, wherein a spacing between tooth tips of two successive sawing teeth is between 20 μm and 150 μm, wherein the hair-severing member is mounted to the support in a position relative to the skin engagement surface such that the hair severing edge is exposed to skin of a user for sawing through hairs present on the skin by means of the sawing teeth when the skin engagement surface is in contact with the skin, and is suspended relative to the support for allowing movement of each sawing tooth in a respective local direction of extension of the hair-severing edge at a position of the sawing tooth;
- and
- driving the hair-severing member of the razor relative to the support of the razor, using a drive coupled to the hair-severing member, such that each sawing tooth of the hair-severing member moves in the respective local direction of extension of the hair-severing edge of the hair-severing member with an average velocity larger than or equal to 10 m/s.
A razor comprising:
- a support;
- a skin engagement surface;
- and
- a hair-severing member having a hair-severing edge and a plurality of sawing teeth arranged along the hair-severing edge, each sawing tooth of the plurality of sawing teeth having a tooth tip and tooth edges mutually connected via the tooth tip, wherein a spacing between tooth tips of two successive sawing teeth is between 20 μm and 150 μm;
- wherein the hair-severing member is mounted to the support in a position relative to the skin engagement surface such that the hair-severing edge is exposed to skin of a user for sawing through hairs present on the skin by means of the sawing teeth when the skin engagement surface is in contact with the skin,
- wherein the hair-severing member is suspended relative to the support to enable movement of each sawing tooth in a respective local direction of extension of the hair-severing edge at a position of the sawing tooth;
- and
- a drive coupled to the hair-severing member and configured to drive the hair-severing member relative to the support such that each sawing tooth moves in the respective local direction of extension of the hair-severing edge according to a rotational movement in a single direction.
