Abstract
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.
Claims5
A shaving system comprising:
- a handle having a distal end and a proximal end,
- a shaving assembly mounted on the handle, and including an interface element configured to provide a mechanical engagement between the shaving assembly and handle,
- wherein the interface element includes an appendage protruding therefrom, and the distal end of the handle includes a receiving portion in form of a hollow, central cavity configured to receive the appendage, and
- a magnetic portion configured to provide a magnetic force between the handle and shaving assembly sufficient to retain the shaving assembly on the handle between shaving strokes;
- wherein the magnetic portion comprises at least one magnet disposed in the hollow, central cavity of the receiving portion, and a ferrous material disposed in a recess at an end of the appendage, and
- wherein the appendage is substantially stationary relative to the receiving portion during shaving.
