Abstract
A razor blade assembly having a razor cartridge connected to a handle via a pivoting mechanism. The razor cartridge rotates about a virtual pivot axis produced by the pivoting mechanism. The virtual pivot axis is positioned in a virtual pivot axis region located forward of the cartridge midpoint toward the front edge of the cartridge and into the skin.
Claims6
A razor cartridge that rotates about a virtual pivot axis, the razor cartridge is removably connected to a handle via a pivoting mechanism and comprises a front edge, a rear edge and a midpoint between the front edge and the rear edge;
- a guard member near the front edge and a cap member near the rear edge;
- at least one blade between the guard member and the cap member;
- and a cutting plane tangent to the guard member and the cap member;
- the virtual pivot axis is positioned in a virtual pivot axis region located forward of the cartridge midpoint toward the front edge of the cartridge and into the skin, the virtual pivot axis region is defined by a first boundary and a second boundary, the first and second boundaries lie on X and Y axes having an origin located on the cutting plane at the cartridge midpoint wherein the X axis extends forward toward the front edge of the cartridge in a +X direction parallel to the cutting plane and the Y axis extends away from the skin in a +Y direction perpendicular to the cutting plane wherein the first boundary extends from the cartridge midpoint, perpendicular to the cutting plane in a −Y direction along a line defined by X=0 and the second boundary extends from the cartridge midpoint in a +X direction along a line defined by Y=−0.1X.
