MAGNETIC ATTACHMENT FOR SHAVING CARTRIDGE
Shaving systems are disclosed that include a replaceable shaving assembly and a cartridge connecting structure for connecting the shaving assembly to a handle. In preferred implementations, the cartridge connecting structure has a magnetic portion configured to help draw the cartridge onto the handle and retain the cartridge in place when the razor is not in contact with the skin, and a mechanical engagement that provides the necessary retention forces required to keep the system intact during shaving.
1 . A handle for a shaving system, the handle comprising:
an elongate handle body having a distal end and a proximal end,
an appendage protruding from the distal end, and
a magnetic portion comprising at least one permanent magnet disposed in a recess at a distal end of the appendage.
2 . The shaving system of claim 1 wherein the appendage is disposed so that a long axis of the appendage is at an angle of +30 degrees to −30 degrees with respect to a crossbar center of the handle, and the handle further includes a generally planar rim surface surrounding the appendage.
3 . The shaving system of claim 2 wherein the rim surface on the handle is disposed at an angle of about 10 to 20 degrees with respect to a longitudinal axis of inertia of the handle.
4 . The shaving system of claim 1 wherein the appendage is in the form of a cuboid having radiused edges.
5 . The shaving system of claim 1 wherein the permanent magnet is centered along the length of the appendage.
6 . The shaving system of claim 1 wherein the distal end of the handle includes a yoke having a pair of arms and a central portion bridging the arms, the central portion having a length, and the appendage extends outwardly from the central portion along the length thereof.
