Abstract

Replaceable shaving assemblies are disclosed that include a blade unit, a shell bearing element, and an interface element. The interface element is configured to removeably connect the shaving assembly to a handle, on which the blade unit is pivotably mounted. In some cases, a return element is integrally formed on the shell bearing unit between the blade unit and interface element. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

First claim

What is claimed is:

1. A replaceable shaving assembly comprising:
a blade unit comprising a plurality of longitudinally extending blades and defining an open rinsing area surrounding the blades;
a shell bearing unit, mounted on a back surface of the blade unit, the shell bearing unit defining a pair of arcuate members disposed outside of the open rinsing area; and
an interface element, configured to removeably connect the blade unit to a handle, on which the shell bearing unit is pivotably mounted.

2. The shaving assembly of claim 1 wherein the shell bearing unit interacts with the interface element.

3. The shaving assembly of claim 1 wherein said pair of arcuate members defines articulating surfaces that are configured to enable pivoting of the blade unit with respect to the interface element.

4. The shaving assembly of claim 1 wherein the shell bearing unit includes a return element formed integrally with the shell bearing unit.

5. The shaving assembly of claim 4 wherein the return element is configured to bias the blade unit towards a rest position with respect to a pivot axis that is generally parallel to a long axis of the blade unit.

6. The shaving assembly of claim 4 , wherein the return element comprises a synthetic elastomer or natural rubber material.

7. The shaving assembly of claim 4 wherein the return element comprises an elongated member that extends longitudinally between the arcuate members.

8. The shaving assembly of claim 7 , wherein the elongated member includes an opening configured to receive a protrusion extending from the interface element.

9. A shaving system comprising:
a handle having a distal end and a proximal end; and
mounted on the handle, a shaving assembly comprising a blade unit comprising a plurality of longitudinally extending blades and defining an open rinsing area surrounding the blades; a shell bearing unit, mounted on a back surface of the blade unit, the shell bearing unit defining a pair of arcuate members disposed outside of the open rinsing area; and an interface element, configured to removeably connect the blade unit to the handle, on which the shell bearing unit is pivotably mounted.

10. The shaving system of claim 9 wherein the shell bearing unit interacts with the interface element.

11. The shaving system of claim 9 wherein said pair of arcuate members defines articulating surfaces that are configured to enable pivoting of the blade unit with respect to the interface element.

12. The shaving system of claim 9 wherein the shell bearing unit includes a return element formed integrally with the shell bearing unit.

13. The shaving system of claim 12 wherein the return element is configured to bias the blade unit towards a rest position with respect to a pivot axis that is generally parallel to a long axis of the blade unit.

14. The shaving system of claim 12 , wherein the return element comprises a synthetic elastomer or natural rubber material.

15. The shaving system of claim 12 , wherein the return element comprises an elongated member that extends longitudinally between the arcuate members.

16. The shaving system of claim 15 , wherein the elongated member includes an opening configured to receive a protrusion extending from the interface element.

17. A method of shaving comprising contacting a user's skin with a blade unit of a shaving system comprising a handle having a distal end and a proximal end, and a replaceable shaving assembly comprising a blade unit comprising a plurality of longitudinally extending blades and defining an open rinsing area surrounding the blades, a shell bearing unit, mounted on a back surface of the blade unit, the shell bearing unit defining a pair of arcuate members disposed outside of the open rinsing area, an interface element configured to removeably connect the blade unit to a handle, the shell bearing unit being pivotably mounted on the interface element, and a return element disposed between the blade unit and the interface element.

18. A replaceable shaving assembly comprising:
a blade unit,
a blade unit interface element mounted on the blade unit, and
a handle interface element on which the blade unit interface element is pivotably mounted, the handle interface element being configured to removably receive a handle,
wherein the blade unit interface element includes a return element configured to apply a return force to the blade unit.

19. The shaving assembly of claim 18 wherein the return element is configured to bias the blade unit towards a rest position with respect to a pivot axis that is generally parallel to a long axis of the blade unit.

20. The shaving assembly of claim 18 wherein the return element comprises a synthetic elastomer or natural rubber material.

21. The shaving assembly of claim 18 wherein the return element comprises an elongated member that extends generally parallel to the longitudinal axis of the blade unit.

22. The shaving assembly of claim 21 wherein the blade unit interface element includes a pair of spaced, generally parallel arcuate members, and the elongated member extends between the arcuate members.

23. The shaving assembly of claim 21 wherein the elongated member includes an opening configured to receive a protrusion extending from the handle interface element.

24. The shaving assembly of claim 18 wherein the return force comprises a torsional force.
