Abstract

A shaving device comprising a head assembly including a support member having at least one support member magnet and a blade cartridge having at least one face with at least one razor blade and configured to be rotatably coupled to the support member about a pivot axis. The blade cartridge includes at least one blade cartridge magnet having a pole aligned with a pole of the support member magnet to generate a magnetic force that urges the blade cartridge about the pivot axis towards an initial starting position (ISP), wherein the blade cartridge is further configured to rotate about the pivot axis away from the ISP upon application of an external force sufficient to overcome the magnetic force between the support member magnet and the blade cartridge magnet.

Claims

         10 . The shaving device of  claim 8 , wherein said at least one blade cartridge magnet is disposed on at least one lateral edge of said blade cartridge. 
     
     
         11 . The shaving device of  claim 7 , wherein said at least one magnetic force generated by said at least one coupling magnet is a repulsive magnetic force. 
     
     
         12 . The shaving device of  claim 7 , wherein said magnetic force generated by said at least one coupling magnet is an attractive magnetic force. 
     
     
         13 . The shaving device of  claim 1 , wherein said at least one magnet includes a first magnet on said handle and a second magnet on said support member. 
     
     
         14 . The shaving device of  claim 13 , wherein said first magnet and said second magnet are configured to generate an attractive magnetic biasing force. 
     
     
         15 . The shaving device of  claim 13 , wherein said first magnet and said second magnet are configured to generate a repulsive magnetic biasing force. 
     
     
         16 . The shaving device of  claim 15 , wherein said first magnet comprises a central magnet and said second magnet comprises an annular magnet coupled to said support member and having a central region that is aligned with said support member cavity such that said central magnet of said post may be at least partially received therein. 
     
     
         17 . The shaving device of  claim 16 , wherein said blade cartridge is configured to be rotatably coupled to said support member about a pivot axis and comprises a blade cartridge magnet, and wherein said central magnet and said blade cartridge magnet are configured to generate a magnetic biasing force to urge said blade cartridge towards an initial starting position with respect to said pivot axis. 
     
     
         18 . The shaving device of  claim 17 , wherein said magnetic biasing force generated by said central magnet and said blade cartridge magnet is a repulsive magnetic force. 
     
     
         19 . The shaving device of  claim 17 , wherein said magnetic biasing force generated by said central magnet and said blade cartridge magnet is an attractive magnetic force. 
     
     
         20 . The shaving device of  claim 1 , wherein at least one of said support cavity or said handle includes a ramped surface configured to cause said support member to rotate in said first direction.
