Abstract

Claims (41)

1 . A shaving device comprising:

a handle;

a first arm and a second arm;

a blade cartridge configured to be removably secured to said first arm and said second arm and to pivot about a pivot axis during shaving with said shaving device at a selected position, said blade cartridge including a first face and a second face each having at least one razor blade;

a first arm magnet fixedly coupled to said first arm;

wherein said blade cartridge is configured to be aligned with said first arm magnet in a first position relative to said handle, said first position corresponding to a first use position of the first face of said blade cartridge;

wherein said blade cartridge is configured to be aligned with said first arm magnet in a second position relative to said handle, said second position corresponding to a second use position of the second face of said blade cartridge; and

wherein the selected position includes the first position and the second position.

2 . The shaving device of claim 1 , further comprising a first pair of blade cartridge magnets including a first blade cartridge magnet and a second blade cartridge magnet disposed on opposite sides of said pivot axis.

3 . The shaving device of claim 2 , wherein said first pair of blade cartridge magnets are configured to rotate with said blade cartridge about said pivot axis.

4 . The shaving device of claim 3 , wherein said first pair of blade cartridge magnets are fixed to a first lateral edge of the blade cartridge.

5 . The shaving device of claim 2 , wherein said first arm magnet is configured to generate a first attractive magnetic force with said first blade cartridge magnet when said blade cartridge is aligned in the first use position, and wherein said first arm magnet is configured to generate a second attractive magnetic force with said second blade cartridge magnet when said blade cartridge is aligned in said second use position.

6 . The shaving device of claim 1 , further comprising a single blade cartridge magnet disposed on opposite sides of said pivot axis.

7 . The shaving device of claim 6 , wherein said single blade cartridge magnet is configured to rotate with said blade cartridge about said pivot axis.

8 . The shaving device of claim 7 , wherein said single blade cartridge magnet is fixed to a first lateral edge of the blade cartridge.

9 . The shaving device of claim 6 , wherein said first arm magnet is configured to generate a first attractive magnetic force with said single blade cartridge magnet when said blade cartridge is aligned in the first use position, and wherein said first arm magnet is configured to generate a second attractive magnetic force with said single blade cartridge magnet when said blade cartridge is aligned in the second use position.

10 . The shaving device of claim 1 , further comprising at least one ferrous component configured to rotate with said blade cartridge about said pivot axis, wherein said first arm magnet is configured to generate an attractive magnet force with said at least one ferrous component to align said blade cartridge in said first and said second use positions.

11 . The shaving device of claim 1 , wherein rotation of said blade cartridge greater than 90 degrees about said pivot axis from said first use position causes said first arm magnet to generate a magnetic force that urges said blade cartridge to rotate to said second use position.

12 . The shaving device of claim 1 , wherein rotation of said blade cartridge less than 90 degrees about said pivot axis from said first use position causes said first arm magnet to generate a magnetic force that urges said blade cartridge to rotate back to said first use position.

13 . A shaving device comprising:

a handle;

a first arm and a second arm;

a blade cartridge configured to be removably secured to said first arm and said second arm and to pivot about a pivot axis during shaving with said shaving device at a selected position, said blade cartridge including a first face and a second face each having at least one razor blade;

a first arm magnet fixedly coupled to said first arm;

a first pair of blade cartridge magnets including a first blade cartridge magnet and a second blade cartridge magnet disposed on opposite sides of said pivot axis;

wherein said first blade cartridge magnet is configured to be aligned with said first arm magnet when said first face of said blade cartridge is arranged in a first position relative to said handle;

wherein said second blade cartridge magnet is configured to be aligned with said first arm magnet when said second face of said blade cartridge is arranged in a second position relative to said handle; and

wherein the selected position includes the first position and the second position.

14 . The shaving device of claim 13 , wherein said first position corresponds to a first use position of the first face of said blade cartridge and said second position corresponds to a second use position of the second face of said blade cartridge.

15 . The shaving device of claim 13 , wherein said first pair blade of cartridge magnets are configured to pivot with said blade cartridge about said pivot axis.

16 . The shaving device of claim 13 , wherein rotation of said blade cartridge greater than 90 degrees about said pivot axis from said first use position causes said first arm magnet to generate a magnetic force that urges said blade cartridge to rotate to said second use position.

17 . The shaving device of claim 13 , wherein rotation of said blade cartridge less than 90 degrees about said pivot axis from said first use position causes said first arm magnet to generate a magnetic force that urges said blade cartridge to rotate back to said first use position.

18 . A shaving device comprising:

a handle;

a support frame including a first arm and a second arm;

a blade cartridge configured to be secured to said support frame and to pivot about a pivot axis during shaving with said shaving device at a selected position, said blade cartridge including a first face and a second face each having a plurality of razor blades;

a first arm magnet fixedly coupled to said first arm;

a first blade cartridge magnet configured to pivot with said blade cartridge about said pivot axis during use of said shaving device;

wherein said first blade cartridge magnet and said first arm magnet are configured to generate a first magnet force that urges said blade cartridge to a first initial starting position relative to said handle, the selected position including the first initial starting position.

19 . The shaving device of claim 18 , wherein said blade cartridge is removably secured to said support frame.

20 . The shaving device of claim 18 , wherein said first magnet force includes an attractive magnetic force.
