Abstract
A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.
Claims20
A shaving device comprising:
- a handle;
- a blade cartridge support member configured to extend from the handle, the blade cartridge support member comprising:
- a first arm extending from a yoke, wherein a position of said first arm is fixed relative to the handle;
- a second arm extending from said yoke;
- and
- a first blade cartridge support member magnet coupled to said first arm;
- a blade cartridge comprising:
- a first face and a second face, wherein at least one of said first face or second face comprises at least one razor blade;
- and
- a first lateral end and a second lateral end;
- one or more pivot pins extending at least partially between said first arm and said second arm and configured to pivotably couple said blade cartridge to said first arm and said second arm of said support member such that said blade cartridge is configured to rotate about a pivot axis extending through said one or more pivot pins and through said blade cartridge;
- and
- a first blade cartridge magnet coupled to said first lateral end, said first blade cartridge magnet configured to generate a magnetic force with said first blade cartridge support member magnet to urge said blade cartridge about said pivot axis back towards an initial starting position in response to a shaving force which urges said blade cartridge away from said initial starting position.
