Abstract

Shaving razors and shaving assemblies for wet shaving are disclosed, which include a blade unit pivotably mounted on arms extending from an interface element. The arms have features that allow them to flex, in some cases in a differential manner depending on the direction of applied forces.

First claim

What is claimed is:

1. A shaving razor comprising:
a razor handle having a distal end, and
mounted on the distal end, a shaving assembly comprising:
a blade unit comprising a plurality of longitudinally extending blades; and
an interface element, configured to connect the blade unit to the handle;
wherein the blade unit and the interface element include cooperating elements that allow the blade unit to pivot with respect to the interface element, the cooperating elements including a pair of arms extending from the interface element towards the blade unit; and
wherein each of the arms includes a non-elastomeric post and an elastomeric outer layer in contact with the post, the elastomeric layer having a groove disposed on an inner surface of each arm, facing the other arm.

2. The razor of claim 1 , wherein the interface element is configured to removably connect the blade unit to the handle.

3. The razor of claim 1 wherein the elastomeric outer layer surrounds the post.

4. The razor of claim 1 wherein the post has an asymmetric cross-section.

5. The razor of claim 1 wherein the post has a symmetric cross-section.

6. The razor of claim 5 wherein the cross-section is circular.

7. The razor of claim 1 wherein the groove extends circumferentially around at least a portion of the arm.

8. The razor of claim 1 wherein the post includes a notch disposed along its length.

9. The razor of claim 1 wherein each arm further includes a finger extending from a distal end of the arm.

10. The razor of claim 1 wherein each arm further includes a shell bearing member extending from a distal end of the arm.

11. A replaceable shaving assembly comprising:
a blade unit comprising a plurality of longitudinally extending blades; and
an interface element, configured to removeably connect the blade unit to a handle;
wherein the blade unit and the interface element include cooperating elements that allow the blade unit to pivot with respect to the interface element, the cooperating elements including a pair of arms extending from the interface element towards the blade unit; and
wherein each of the arms includes a non-elastomeric post and an elastomeric outer layer in contact with the post, the elastomeric layer having a groove disposed on an inner surface of each arm, facing the other arm.

12. The shaving assembly of claim 11 wherein the elastomeric outer layer surrounds the post.

13. The shaving assembly of claim 11 wherein the post has an asymmetric cross-section.

14. The shaving assembly of claim 11 wherein the post has a symmetric cross-section.

15. The shaving assembly of claim 14 wherein the cross-section is circular.

16. The shaving assembly of claim 11 wherein the groove extends circumferentially around at least a portion of the arm.

17. The shaving assembly of claim 11 wherein the post includes a notch disposed along its length.

18. The shaving assembly of claim 11 wherein each arm further includes a finger extending from a distal end of the arm.

19. The shaving assembly of claim 11 wherein each arm further includes a shell bearing member extending from a distal end of the arm.

20. A replaceable shaving assembly comprising:
a blade unit comprising a plurality of longitudinally extending blades; and

an interface element, configured to removeably connect the blade unit to a handle;
wherein the blade unit and the interface element include cooperating elements that allow the blade unit to pivot with respect to the interface element, the cooperating elements including a pair of arms extending from the interface element towards the blade unit; and
wherein each of the arms includes a non-elastomeric post and an elastomeric outer layer in contact with the post, the elastomeric layer having a groove disposed on an outer surface of each arm, facing away from the other arm.

21. The shaving assembly of claim 20 wherein the elastomeric outer layer surrounds the post.

22. The shaving assembly of claim 20 wherein the post has an asymmetric cross-section.

23. The shaving assembly of claim 20 wherein the post has a symmetric cross-section.

24. The shaving assembly of claim 23 wherein the cross-section is circular.

25. The shaving assembly of claim 20 wherein the post includes a notch disposed along its length.

26. The shaving assembly of claim 20 wherein each arm further includes a finger extending from a distal end of the arm.

27. The shaving assembly of claim 20 wherein each arm further includes a shell bearing member extending from a distal end of the arm.

28. A shaving razor comprising: a razor handle having a distal end, and mounted on the distal end, a shaving assembly comprising: a blade unit comprising a plurality of longitudinally extending blades; and an interface element, configured to connect the blade unit to the handle; wherein the blade unit and the interface element include cooperating elements that allow the blade unit to pivot with respect to the interface element, the cooperating elements including a pair of arms extending from the interface element towards the blade unit; and wherein each of the arms includes a non-elastomeric post and an elastomeric outer layer in contact with the post, the elastomeric layer having a groove disposed on an outer surface of each arm, facing away from the other arm.
