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.

First claim

What is claimed is:

1. 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 having a rear surface and one or more clip member(s) extending from the rear surface, 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 disposed on the interface element, the return element comprising one or more elongated band(s) of elastomer, the band(s) having a longitudinal axis extending generally parallel to a longitudinal axis of the blade unit, wherein the clip member(s) extend over and interact with the band(s).

2. The shaving system 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.

3. The shaving system of claim 2 wherein the return element is in the form of two bands positioned adjacent to and inboard of the fingers.

4. The shaving system of claim 3 wherein the blade unit includes two of the clip members, under which the two bands are positioned.

5. The shaving system of claim 1 wherein pivoting of the blade unit is about an axis that is generally parallel to the longitudinal axis of the blade unit.

6. The shaving system of claim 1 wherein the return element is in the form of a single band positioned generally centrally along the length of the interface element.

7. The shaving system of claim 1 wherein the blade unit is mounted directly on the interface element.

8. The shaving system of claim 1 wherein the return element is supported and spaced from a surface of the interface element that extends generally parallel to the longitudinal axis of the band(s) by support elements that extend generally perpendicularly to a long axis of the interface element.

9. A replaceable shaving assembly comprising:
a blade unit having a rear surface and one or more clip member(s) extending from the rear surface;
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, the return element comprising one or more elongated band(s) of elastomer, the band(s) having a longitudinal axis extending generally parallel to a longitudinal axis of the blade unit;
wherein the clip member(s) extend over and interact with the band(s).

10. The shaving assembly of claim 9 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.

11. The shaving assembly of claim 10 wherein the return element is in the form of two bands positioned adjacent to and inboard of the fingers.

12. The shaving assembly of claim 11 wherein the blade unit includes two of the clip members, under which the two bands are positioned.

13. The shaving assembly of claim 9 wherein pivoting of the blade unit is about an axis that is generally parallel to the longitudinal axis of the blade unit.

14. The shaving assembly of claim 9 wherein the return element is in the form of a single band positioned generally centrally along the length of the interface element.

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

16. The shaving assembly of claim 9 wherein the return element is supported and spaced from a surface of the interface element that extends generally parallel to the longitudinal axis of the band(s) by support elements that extend generally perpendicularly to a long axis of the interface element.
