MAGNETIC ATTACHMENT FOR SHAVING CARTRIDGE

摘要

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.

主权项

1. A shaving system comprising:
a handle having a longitudinal axis of inertia, a distal end, and a proximal end, the distal end comprising: an appendage protruding therefrom, a rim surface surrounding the appendage, wherein the rim surface is disposed at an angle of about 10 to 20 degrees with respect to the longitudinal axis of inertia of the handle, and wherein the appendage is disposed so that a longitudinal axis of the appendage is at an angle of +30 degrees to −30 degrees with respect to an axis perpendicular to the rim surface; a shaving assembly coupled to the appendage, the shaving assembly comprising: an interface element having a receiving cavity configured to receive the appendage, and a blade unit pivotally mounted on the interface element, wherein the interface element and appendage are configured to have a mechanical engagement only during shaving; and a magnetic attachment system comprising a magnet and a ferrous element, wherein the magnetic attachment system is configured to provide a magnetic force sufficient to retain the shaving assembly on the handle between shaving strokes, and the magnet and the ferrous element have planar surfaces that are disposed in face-to-face contact when the shaving assembly is mounted on the handle.
