Abstract
Shaving apparatus having at least one cutting unit with an external cutting member and a movable internal cutting member. An energy-dissipating system is provided between mutually movable parts of the internal or an external cutting member to reduce the bouncing effect between the internal and external cutting member after cutting a hair. Such an energy-dissipating system may for example be an element with visco-elastic properties.
Claims13
A shaving apparatus comprising:
- a drive member;
- an external cutting member provided with hair trap openings bounded by cutting edges;
- an internal cutting member including
- a backing plate,
- a coupling member positioned at a center of the external and internal cutting members for coupling to the drive member, and
- a mass component provided with a disc from which cutting elements are provided with cutting edges for cooperating with the cutting edges of the external cutting member for cutting hairs, the drive member for driving the internal cutting member with respect to the external cutting member;
- and
- an energy-dissipating system positioned outside the coupling member between the disc and the backing plate.

A shaving apparatus comprising:
- a drive member;
- an external cutting member provided with hair trap openings bounded by cutting edges;
- an internal cutting member including
- a backing plate,
- a coupling member positioned at a center of the external and internal cutting members for coupling to the drive member, and
- a mass component having cutting elements provided with cutting edges for cooperating with the cutting edges of the external cutting member for cutting hairs, the drive member configured to drive the internal cutting member with respect to the external cutting member;
- and
- an energy-dissipating system positioned outside the coupling member between the external cutting member and the backing plate.
A cutting unit comprising:
- an external cutting member including hair trap openings bounded by cutting edges;
- an internal cutting member drivable with respect to the external cutting member, the internal cutting member including:
- a backing plate,
- a coupling member positioned substantially at a center of the external and internal cutting members for coupling to a drive member, and
- a mass component having cutting elements provided with cutting edges for cooperating with the cutting edges of the external cutting member for cutting hairs;
- and
- an energy-dissipating system positioned outside the coupling member between the backing plate and the external cutting member.
