Shaving device

1. A shaving device comprising:

a head assembly comprising:

a support member comprising a first arm including a first support member magnet and a second arm including a second support member magnet; and

a blade cartridge having a first and a second opposite lateral end and at least one face with at least one razor blade, said blade cartridge configured to be rotatably coupled to said first and said second arms of said support member about a pivot axis extending through said first and said second lateral ends, said first lateral end further comprising a first blade cartridge magnet and said second lateral end comprising a second blade cartridge magnet, said first and said second blade cartridge magnets having a pole aligned with a pole of said first and said second support member magnets, respectively, to generate a magnetic force that urges said blade cartridge about said pivot axis towards an initial starting position (ISP), wherein said blade cartridge is further configured to rotate about said pivot axis away from said ISP upon application of an external force sufficient to overcome said magnetic force between said first and said second support member magnets and said first and said second blade cartridge magnets.

2. The shaving device of claim 1 , wherein said poles of said first support member magnet and said first blade cartridge magnet are aligned to generate a repulsive magnetic force.

3. The shaving device of claim 2 , wherein said first blade cartridge magnet is disposed above said pivot axis closer to a top edge of said blade cartridge.

4. The shaving device of claim 1 , wherein said poles of said first support member magnet and said first blade cartridge magnet are aligned to generate an attractive magnetic force.

5. The shaving device of claim 4 , wherein said first blade cartridge magnet is disposed below said pivot axis opposite to a top edge of said blade cartridge.

6. The shaving device of claim 1 , further comprising at least one ISP protrusion configured to establish said ISP of said blade cartridge, wherein said ISP protrusion extends outwardly from said blade cartridge and engages said support member.

7. The shaving device of claim 1 , further comprising at least one ISP protrusion configured to establish said ISP of said blade cartridge, wherein said ISP protrusion extends outwardly from said support member and engages said blade cartridge.

8. The shaving device of claim 1 , wherein said first and said second arm comprise a first and a second pin receptacle, respectively,

wherein blade cartridge further comprises one or more pivot pins extending outward from said first and second opposite lateral ends of said blade cartridge along said pivot axis and configured to be received in said first and said second pin receptacle.

9. The shaving device of claim 8 , wherein said first and said second pin receptacle include a first and a second open end, respectively, configured to allow said one or more pivot pins to enter said first and said second receptacle and to be removed from said first and said second pin receptacle.

10. The shaving device of claim 9 , wherein said first and said second support member magnet are disposed proximate to said first and said second pin receptacle, respectively.

11. The shaving device of claim 10 , wherein said first and said second blade cartridge magnet are disposed proximate to said one or more pivot pins.

12. The shaving device of claim 9 , wherein at least a portion of said one or more pivot pins includes a non-circular cross-section.

13. The shaving device of claim 12 , wherein said non-circular cross-section includes a first traverse dimension that is less than a second transverse dimension, said first traverse dimension being approximately perpendicular to said second traverse dimension.

14. The shaving device of claim 12 , wherein said non-circular cross-section of said one or more pivot pins is configured to be received through said open end of said first and said second pin receptacle in a first orientation, but cannot pass back through said first and said second pin receptacle when rotated about said pivot axis to a second orientation.

15. The shaving device of claim 9 , further comprising at least one rotation limiter configured to generally limit the rotation of said blade cartridge about said pivot axis PA to a predefined range.

16. The shaving device of claim 15 , wherein at least one of said first or said second arms includes a rotation limiter cavity, and wherein said at least one rotation limiter includes a projection extending radially outward about said one or more pivot pin(s) that forms a stop when it engages a portion of said rotation limiter cavity to prevent further rotation of said blade cartridge relative to said first and said second arms.

17. The shaving device of claim 1 , wherein said first and said second support member magnet and said first and said second blade cartridge magnet are configured to generate a magnetic force that releasably couples said blade cartridge to said support member.

18. The shaving device of claim 1 , wherein said ISP corresponds to a position about said pivot axis wherein poles of said first support member magnet and said first blade cartridge magnet and poles of said second support member magnet and said second blade cartridge magnet are configured to be aligned with respect to each other.

19. The shaving device of claim 1 , wherein said pivot axis extends through said first and said second arm.

20. The shaving device of claim 1 , wherein said pivot axis extends parallel to said at least one razor blade.
