Abstract

Replaceable shaving assemblies are disclosed that include a blade unit, an interface element configured to removeably connect the blade unit to a handle, on which the blade unit is pivotably mounted, and a return element disposed on the interface element. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

Claims

1. A replaceable shaving assembly comprising:

a blade unit;

an interface element configured to removeably connect the blade unit to a handle, on which the blade unit is pivotably mounted; and

an elastomeric return element disposed on the interface element in the form of a single band positioned generally centrally along the length of the interface element.

2. The shaving assembly of claim 1 wherein the return element is configured to interact with a corresponding structure on the blade unit so as to provide a return force.

3. The shaving assembly of claim 1 wherein the blade unit is pivotably mounted on the interface element by the positioning of a pair of fingers, which extend from the interface element, in receiving bores or clips disposed on the blade unit.

4. The shaving assembly of claim 1 wherein pivoting of the blade unit is about an axis that is generally parallel to the long axis of the blade unit.

5. The shaving assembly of claim 2 wherein the corresponding structure comprises a clip disposed on the blade unit under which the return element is positioned.

6. The shaving assembly of claim 5 wherein the clip is generally centrally located along a longitudinal axis of the blade unit.

7. The shaving assembly of claim 6 wherein the blade unit includes a pivot stop and the clip is disposed adjacent to the pivot stop.

8. The shaving assembly of claim 1 wherein the return element has a longitudinal axis extending generally parallel to a longitudinal axis of the blade unit.

9. The shaving assembly of claim 1 wherein the blade unit is mounted directly on the interface unit.

10. The shaving assembly of claim 8 wherein the return element is supported and spaced from the main surface of the interface element by support elements that extend generally perpendicularly to a long axis of the interface element.

11. A shaving system comprising:

a handle having a distal end and a proximal end; and

mounted on the handle, a replaceable shaving assembly that includes a blade unit, an interface element configured to removeably connect the blade unit to the handle, on which the blade unit is pivotably mounted, and an elastomeric return element in the form of a single band positioned generally centrally along the length of the interface element.

12. The shaving system of claim 11 wherein the return element is configured to interact with a corresponding structure on the blade unit so as to provide a return force.

13. The shaving system of claim 11 wherein the blade unit is pivotably mounted on the interface element by the positioning of a pair of fingers, which extend from the interface element, in receiving bores or clips disposed on the blade unit.

14. The shaving system of claim 11 wherein pivoting of the blade unit is about an axis that is generally parallel to the long axis of the blade unit.

15. The shaving system of claim 12 wherein the corresponding structure comprises a clip disposed on the blade unit under which the return element is positioned.

16. The shaving system of claim 15 wherein the clip is generally centrally located along a longitudinal axis of the blade unit.

17. The shaving system of claim 16 wherein the blade unit includes a pivot stop and the clip is disposed adjacent to the pivot stop.

18. The shaving system of claim 11 wherein the return element has a longitudinal axis extending generally parallel to a longitudinal axis of the blade unit.

19. The shaving system of claim 11 wherein the blade unit is mounted directly on the interface unit.

20. The shaving system of claim 18 wherein the return element is supported and spaced from the main surface of the interface element by support elements that extend generally perpendicularly to a long axis of the interface element.

21. A method of shaving comprising contacting the skin with the blade unit of a shaving system comprising a handle having a distal end and a proximal end, and a replaceable shaving assembly, mounted on the distal end of the handle, that includes a blade unit, an interface element configured to removeably connect the blade unit to a handle, on which the blade unit is pivotably mounted, and an elastomeric return element in the form of a single band positioned generally centrally along the length of the interface element.
