Abstract
An electric shaver, and in particular an electric shaver wherein are included blades which while rotating around their own centers also orbit around another axis, thus providing that the blades sweep a large area.
Claims43
An apparatus for shaving hair, comprising:
- (a) a housing including a body portion and a shaving head;
- (b) a carrier rotatably driven about a primary axis, the carrier having opposite ends;
- (c) a cutting blade rotatably mounted in the shaving head to each opposite end of the carrier, each of the cutting blades being rotatable with respect to the carrier about a secondary axis and the cutting blades being selected to provide overlapping sweeps, each blade defining a respective sweep;
- and
- (d) a screen that engages with the blades attached to a wall of the housing.
2 more elements
An apparatus for shaving hair, comprising:
- (a) a housing;
- (b) a plurality of cutting blades within the housing, each rotatable about a different secondary axis, each secondary axis capable of orbiting around a primary axis;
- (c) means for driving each secondary axis in an orbital movement about the primary axis;
- and
- (d) a screen attached to a wall of the housing and also engaging the blades.
2 more elements
An apparatus for shaving, comprising:
- (a) a housing;
- (b) a plurality of carriers rotatably mounted to the housing, each carrier being rotatable about a primary axis and each carrier defining a rotation area, the rotation areas of neighboring carriers overlapping;
- and
- (c) a plurality of blades rotatably mounted to each carrier, each blade being rotatable about a secondary axis with respect to its carrier and each blade having a sweep defined by a combination of its own rotation and the rotation area of the respective carrier.
1 more element
An apparatus for shaving, comprising:
- (a) a housing;
- (b) a carrier rotatably mounted to the housing, (c) a plurality of swing arms, each having a near extremity pivotally connected with the carrier;
- (d) a gear mounted to a far extremity of each swing arm so that it can rotate about a center line;
- and
- (e) a blade mounted to each gear and rotatable therewith about the same center line so that when the carrier rotates, the swing arms are outwardly urged by centrifugal force until the gears engage with a gear ring, the blades then having an orbital movement defined by the shape of the gear ring while rotating about their center lines.
