Abstract

A razor treatment system includes a razor having a head, and a razor treatment device including a drum rotationally supported within the razor treatment device, at least two cam members supported within the razor treatment device, at least two guide members configured to cooperate with the cam members to expose the blade, and a first actuating member configured to effect rotation of the drum. The head includes a cover for housing a blade. The cover is configured to expose the blade. The razor interfaces with the razor treatment device to move the cover of the razor to expose the blade. Each cam member may define a cam track that guides linear retraction of the blade, rotational movement of the blade and cover, and linear extension of the blade into a position between the drums.

Claims (35)

1. A razor treatment system, comprising:

a razor having a head, wherein the head includes a cover for housing a blade, wherein the cover is configured to expose the blade; and

a razor treatment device including a drum rotationally supported within the razor treatment device, wherein the razor interfaces with the razor treatment device to move the cover of the razor to expose the blade for treatment of the blade by the drum.

2. The razor treatment system as claimed in claim 1 , wherein the razor treatment system further comprises a sharpener comprising at least two cam members supported within the razor treatment device, at least two guide members configured to cooperate with the cam members to expose the blade, and a first actuating member configured to effect rotation of the guide members.

3. The razor treatment system as claimed in claim 2 , wherein each cam member defines a cam track that guides linear retraction of the blade, rotational movement of the blade and cover, and linear extension of the blade into a position on the drum.

4. The razor treatment system as claimed in claim 1 , wherein the blade of the razor is spring-biased in the cover.

5. The razor treatment system as claimed in claim 4 , wherein the razor further comprises at least one cradle member positioned on the head of the razor and configured to hold the spring-biased blade within the cover of the razor, wherein the blade is spring-biased against the cradle member and contacts the cradle member at a portion that is abraded to position a cutting edge of the blade in a same position after each use of the razor treatment system.

6. The razor treatment system as claimed in claim 2 , wherein at least a portion of a surface of the drum comprises an abrasive material.

7. The razor treatment system as claimed in claim 6 , further comprising a second drum having at least a portion of a surface thereof comprising an abrasive material.

8. The razor treatment system as claimed in claim 6 , wherein the abrasive material is provided in a spiral configuration around the outer surface of the drum.

9. The razor treatment system as claimed in claim 3 , wherein the razor further includes a pair of pins, each pin extending from an end of a longitudinal axis of the blade and extending out of the cover of the razor, and wherein the pins are movable along the cam track of each cam member by each guide member in order to expose the blade in the razor treatment device.

10. The razor treatment system as claimed in claim 9 , wherein each guide member is arcuate-shaped and defines at least two recesses with surfaces configured to guide the pins along the cam track of each cam member.

11. The razor treatment system as claimed in claim 1 , wherein the razor further comprises at least one latching mechanism positioned on at least one of a top surface of the cover and a bottom surface of the cover.

12. The razor treatment system as claimed in claim 2 , wherein the razor treatment device further includes a stropping portion.

13. The razor treatment system as claimed in claim 12 , wherein the stropping portion comprises another rotatably mounted drum comprising on a surface thereof a material suitable to strop the blade.

14. A shaving razor, comprising:

a handle; and

a head comprising a blade and a cover, the head pivotally connected to the handle, and the cover housing the blade and pivotally connected to the head; and

wherein the cover is rotatable relative to the handle so that the blade is movable relative to the cover to extend from the cover to extend a shaving edge of the blade from the cover.

15. The shaving razor as claimed in claim 14 , wherein the blade is spring-biased within the cover.

16. The shaving razor as claimed in claim 15 , the razor further comprising a pair of pins, wherein each pin extends out of the cover of the razor along a longitudinal axis of the blade.

17. The shaving razor as claimed in claim 15 , the razor further comprising at least one cradle member positioned on the head of the razor and configured to hold the spring-biased blade within the cover of the razor, wherein the blade is spring-biased against the cradle member and contacts the cradle member at a portion that is abraded to position a cutting edge of the blade in a same position after each use of the shaving razor.

18. A razor treatment device, comprising:

a drum rotationally supported within a housing,

at least two cam members supported within the housing,

at least two guide members configured to interact with the cam members to rotate a cover of a shaving razor, and

a first actuating member configured to effect rotation of the guide members.

19. The razor treatment device as claimed in claim 18 , further comprising a second drum rotationally supported within the housing.

20. The razor treatment device as claimed in claim 19 , wherein each cam member defines a cam track that guides linear retraction of a blade of a shaving razor, rotational movement of the blade and a cover of the shaving razor, and linear extension of the blade into a position between the drums.

21. The razor treatment device as claimed in claim 20 , wherein at least a portion of at least one drum comprises an abrasive material.

22. The razor treatment device as claimed in claim 21 , wherein the abrasive material is provided in a spiral configuration around the outer surface of the drums.

23. The razor treatment device as claimed in claim 20 , wherein each guide member is arcuate-shaped and defines at least two recesses with surfaces configured to guide the blade of the shaving razor along the cam track of each cam member.

24. The razor treatment device as claimed in claim 21 , further comprising a stropping portion rotatably supported within the housing.

25. The razor treatment device as claimed in claim 24 wherein the drum and the second drum are rotatably positioned on one side of the razor treatment device and the stropping portion is rotatably positioned on an opposite side of the housing.

26. The razor treatment device as claimed in claim 25 , wherein the stropping portion comprises a rotatably supported drum comprising a surface bearing a material suitable to strop the blade.
