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.

Claims (52)

1. A shaving device comprising:

a handle comprising a first magnet, and

a head assembly comprising:

a support member configured to be detachably coupled to said handle, said support member comprising a second magnet configured to generate a repulsive magnetic force with said first magnet to releasably couple said head assembly to said handle; and

a blade cartridge configured to be pivotably coupled to said support member about a pivot axis, said blade cartridge having a first and a second face wherein at least one of said first or second faces comprises at least one razor blade.

2. The shaving device of claim 1 , wherein one or more magnets are configured to be disposed at one or more of said blade cartridge and/or said support member, said one or more magnets being configured to generate said magnetic biasing force to urge said blade cartridge towards said initial starting position.

3. The shaving device of claim 2 , wherein at least one arm of said support member includes at least one magnet and/or wherein a lateral end of said blade cartridge includes at least one magnet configured to generate said magnetic biasing force.

4. The shaving device of claim 2 , wherein said at least one magnet is configured to be disposed generally in a central region of said support member.

5. The shaving device of claim 4 wherein said blade cartridge includes at least one magnet configured to generate said magnetic biasing force with said at least one magnet disposed in said central region.

6. The shaving device of claim 1 , further comprising least one rotational limiter configured to generally limit rotation of said blade cartridge to a predefined point of rotation with respect to said pivot axis.

7. The shaving device of claim 1 , wherein said support member includes a yoke having a first and a second arm and a base region disposed therebetween, and wherein said blade cartridge includes at least one magnet configured to magnetically engage at least one magnet disposed within said base of said yoke.

8. The shaving device of claim 1 , further comprising a resistive pivot mechanism configured to urge said blade cartridge towards an initial starting position.

9. The shaving device of claim 8 , wherein said resistive pivot mechanism configured to allow said blade cartridge to rotate both clockwise and counter-clockwise within a predefined rotation range from said initial starting position.

10. The shaving device of claim 1 , wherein said resistive pivot mechanism is configured to generate at least one magnetic biasing force to urge said blade cartridge towards said initial starting position.

11. The shaving device of claim 10 , wherein said at least one magnetic biasing force comprises an attractive magnetic force configured to urge said blade cartridge towards said initial starting position.

12. The shaving device of claim 10 , wherein said at least one magnetic biasing force comprises a repulsive magnetic force configured to urge said blade cartridge towards said initial starting position.

13. The shaving device of claim 10 , wherein said resistive pivot mechanism includes magnetic means for urging said blade cartridge towards said initial starting position.

14. The shaving device of claim 1 , wherein the first magnet includes one of an annular magnet or a central magnet and said second magnet includes the other of said annular magnet and central magnet, said central magnet being configured to be at least partially received in a central region of said annular magnet.

15. A shaving device comprising:

a handle comprising a first magnet; and

a head assembly comprising:

a support member configured to be detachably coupled to a handle, said support member comprising a second magnet configured to create a repulsive magnetic force with said first magnet to releasably couple said head assembly to said handle;

a blade cartridge having a first and a second face wherein at least one of said first or second faces comprises at least one razor blade, said blade cartridge being configured to be rotatably coupled to said support member about a pivot axis such that said blade cartridge is pivotable by a user to select one of said first or second faces; and

a resistive pivot mechanism configured to allow a user to rotate said blade cartridge about said pivot axis to select one of a first or a second face position corresponding to said first and second faces of said blade cartridge, respectively, said resistive pivot mechanism configured to allow said blade cartridge to rotate both clockwise and counter-clockwise about said pivot axis from an initial starting position corresponding to said selected face position.

16. The shaving device of claim 15 , wherein said resistive pivot mechanism includes a biasing force configured to urge said blade cartridge towards said initial starting position.

17. The shaving device of claim 16 , wherein said resistive pivot mechanism is configured to generate at least one magnetic biasing force to urge said blade cartridge towards said initial starting position.

18. The shaving device of claim 15 , wherein the first magnet includes at least one annular magnet and said second magnet includes at least one central magnet configured to be at least partially received in a central region of said annular magnet.

19. The shaving device of claim 15 , wherein said second magnet includes at least one annular magnet and said first magnet includes at least one central magnet configured to be at least partially received in a central region of said annular magnet.

20. A shaving device comprising:

a handle comprising a first magnet; and

a head assembly comprising:

a support member configured to be detachably coupled to a handle, said support member comprising a second magnet configured to create a repulsive magnetic force with said first magnet to releasably couple said head assembly to said handle;

a blade cartridge comprising at least one razor blade, said blade cartridge being configured to be rotatably coupled to said support member about a pivot axis; and

a resistive pivot mechanism configured to allow said blade cartridge to rotate at least one of clockwise and/or counter-clockwise about said pivot axis from an initial starting position.

21. The shaving device of claim 20 , wherein said resistive pivot mechanism includes magnetic means for urging said blade cartridge towards said initial starting position.

22. The shaving device of claim 20 , wherein the first magnet includes one of an annular magnet or a central magnet and said second magnet includes the other of said annular magnet and central magnet, said central magnet being configured to be at least partially received in a central region of said annular magnet.

23. The shaving device of claim 20 , wherein said resistive pivot mechanism is configured to generate at least one magnetic biasing force to urge said blade cartridge towards said initial starting position.

24. A shaving device comprising:

a handle;

a head assembly comprising:

a blade cartridge having at least one face comprising at least one razor blade; and

a support member configured to be releasably coupled to said handle;

an annular magnet; and

a central magnet configured to be at least partially received in a central region of said annular magnet;

wherein said annular magnet is disposed in either said handle or said head assembly and said central magnet is disposed in the other one of said handle or said head assembly, and

wherein said poles of said annular magnet and said central magnet are aligned to create a repulsive magnetic force configured to releasably couple said head assembly to said handle.

25. The shaving device of claim 24 , wherein the head assembly includes said annular magnet and said handle includes said central magnet.

26. The shaving device of claim 25 , wherein said handle comprises a handle protrusion extending outward therefrom, said handle protrusion including said central magnet, and wherein said head assembly includes a head assembly cavity extending through said central region of said annular magnet and configured to receive said handle protrusion and said central magnet.
