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 (35)

1. A shaving device comprising:

a handle including a distal end comprising a first and a second handle post extending in a first direction and defining a pendulum swing channel therebetween;

a support member configured to rotate about a pivot axis that is perpendicular to said first direction of said first and said second handle post said support member comprising a support member cavity configured to receive at least a portion of said first and said second handle post and comprising a yoke pendulum at least partially disposed within said support member cavity and extending towards an opening of said support member cavity, said yoke pendulum configured to pass through said pendulum swing channel as said support member rotates about said pivot axis;

wherein a magnetic force urges said yoke pendulum towards said pendulum swing channel.

2. The shaving device of claim 1 , wherein said support member is rotatably coupled to at least one of said first or said second handle post.

3. The shaving device of claim 2 , further comprising at least one pin configured to rotatably couple said support member to at least one of said first or said second handle post.

4. The shaving device of claim 3 , wherein said at least one pin rotatably couples said yoke pendulum to at least one of said first or said second handle post.

5. The shaving device of claim 1 , wherein said yoke pendulum comprises a yoke pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said pendulum swing channel.

6. The shaving device of claim 5 , wherein said handle comprises a ferrous material configured to generate, at least in part, said magnetic force with said yoke pendulum magnet to urge said yoke pendulum towards said pendulum swing channel.

7. The shaving device of claim 5 , wherein said yoke pendulum magnet is disposed proximate a distal end of said yoke pendulum.

8. The shaving device of claim 7 , further comprising at least one pin configured to rotatably couple a distal end of said yoke pendulum to at least one of said first or said second handle post.

9. The shaving device of claim 5 , wherein said yoke pendulum magnet is configured to move along an arcuate pathway as said support member rotates about said pivot axis.

10. The shaving device of claim 1 , wherein said handle comprises a handle pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said pendulum swing channel.

11. The shaving device of claim 10 , wherein said yoke pendulum comprises a ferrous material configured to generate, at least in part, said magnetic force with said handle pendulum magnet to urge said yoke pendulum towards said pendulum swing channel.

12. The shaving device of claim 1 , wherein said yoke pendulum comprises a yoke pendulum magnet and said handle comprises a handle pendulum magnet, said yoke pendulum magnet and said handle pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said pendulum swing channel.

13. The shaving device of claim 12 , wherein said magnetic force comprises an attractive magnetic force, and wherein said yoke pendulum magnet and said handle pendulum magnet configured to generate, at least in part, said attractive magnetic force.

14. The shaving device of claim 12 , wherein said yoke pendulum magnet and said handle pendulum magnet are configured to be aligned coaxially along said first direction when said support member is disposed at an initial starting position.

15. The shaving device of claim 14 , wherein said initial starting position is disposed within said pendulum swing channel.

16. The shaving device of claim 1 , further comprising a lock to fix a position of said support member relative to said handle.

17. The shaving device of claim 1 , wherein said support member is configured to be removably coupled to said handle.

18. The shaving device of claim 1 , wherein said support member is permanently coupled to said handle.

19. The shaving device of claim 1 , wherein said support member further comprises a blade cartridge, said blade cartridge comprising at least one razor blade.

20. A shaving device comprising:

a handle including a distal end comprising a first and a second handle post extending in a first direction and defining a pendulum swing channel therebetween;

a support member comprising a blade cartridge having at least one razor blade, said support member configured to be rotatably coupled to at least one of said first or said second handle post about a pivot axis that is perpendicular to said first direction of said first and said second handle post, said support member further comprising a support member cavity configured to receive at least a portion of said first and said second handle post and comprising a yoke pendulum at least partially disposed within said support member cavity and extending towards an opening of said support member cavity, said yoke pendulum configured to pass through said pendulum swing channel as said support member rotates about said pivot axis;

wherein a magnetic force urges said yoke pendulum towards an initial starting position disposed within said pendulum swing channel.

21. The shaving device of claim 20 , wherein said yoke pendulum comprises a yoke pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said initial starting position.

22. The shaving device of claim 21 , wherein said handle comprises a ferrous material configured to generate, at least in part, said magnetic force with said yoke pendulum magnet to urge said yoke pendulum towards said initial starting position.

23. The shaving device of claim 21 , further comprising at least one pin configured to rotatably couple a distal end of said yoke pendulum to at least one of said first or said second handle post, wherein said yoke pendulum magnet is disposed proximate a distal end of said yoke pendulum.

24. The shaving device of claim 21 , wherein said yoke pendulum magnet is configured to move along an arcuate pathway as said support member rotates about said pivot axis.

25. The shaving device of claim 20 , wherein said handle comprises a handle pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said initial starting position.

26. The shaving device of claim 25 , wherein said yoke pendulum comprises a ferrous material configured to generate, at least in part, said magnetic force with said handle pendulum magnet to urge said yoke pendulum towards said initial starting position.

27. The shaving device of claim 20 , wherein said yoke pendulum comprises a yoke pendulum magnet and said handle comprises a handle pendulum magnet, said yoke pendulum magnet and said handle pendulum magnet configured to generate, at least in part, said magnetic force to urge said yoke pendulum towards said initial starting position.

28. The shaving device of claim 27 , wherein said magnetic force comprises an attractive magnetic force, and wherein said yoke pendulum magnet and said handle pendulum magnet configured to generate, at least in part, said attractive magnetic force.

29. The shaving device of claim 27 , wherein said yoke pendulum magnet and said handle pendulum magnet are configured to be aligned coaxially along said first direction when said support member is disposed at an initial starting position.
