Abstract

Shaving assemblies are disclosed that include a blade unit, an interface element configured to connect the blade unit to a handle, on which the blade unit is pivotably mounted, and an return element disposed between the blade unit and interface element. The return element serves as interface piece, connector and pivot all in one. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.

Claims (23)

1. A replaceable shaving assembly comprising:

a blade unit; and

an interface element configured to removeably connect the blade unit to a handle, on which the blade unit is pivotably mounted, the interface element including a portion configured for magnetic interaction with a corresponding portion on the handle,

the interface element comprising (a) a handle interface portion, having a body configured to receive a distal end of the handle and at least one first rigid protrusion extending from the body, (b) a blade unit interface portion including at least one second rigid protrusion, and (c) a flexible elastomeric return element joining the opposed ends of the first and second rigid protrusions and thus flexibly joining the handle interface portion to the blade unit interface portion,

wherein ends of the first and second rigid protrusions are positioned facing each other in opposed spaced relation such that a longitudinal axis of the second rigid protrusion is generally collinear with a longitudinal axis of the first rigid protrusion.

2. The shaving assembly of claim 1 wherein the return element comprises two spaced apart elastomeric members that extend in a direction generally perpendicular to a longitudinal axis of the blade unit, the shaving assembly comprises two first rigid protrusions and two second rigid protrusions, and one of the elastomeric members connects one of the first rigid protrusions to one of the second rigid protrusions and the other elastomeric member connects the other first rigid protrusion to the other second rigid protrusion.

3. The shaving assembly of claim 1 , 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.

4. The shaving assembly of claim 1 , wherein the return element is pretensioned.

5. The shaving assembly of claim 1 , wherein the return element comprises a thermoplastic elastomer or thermoplastic urethane.

6. The shaving assembly of claim 1 , wherein the return element is molded onto the spaced apart rigid protrusions.

7. The shaving assembly of claim 1 wherein the return element includes two generally H-shaped portions.

8. The shaving assembly of claim 1 wherein the first and second rigid protrusions extend toward each other and are embedded in the return element.

9. A shaving system comprising:

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

a shaving assembly, mounted on the distal end of the handle, the shaving assembly including an interface element configured to connect the blade unit to the handle, and a blade unit that is pivotably mounted on the interface element, the interface element including a portion configured for magnetic interaction with a corresponding portion on the handle,

the interface element comprising (a) a handle interface portion, having a body configured to receive a distal end of the handle and at least one first rigid protrusion extending from the body, (b) a blade unit interface portion including at least one second rigid protrusion, and (c) a flexible elastomeric return element joining the opposed ends of the first and second rigid protrusions and thus flexibly joining the handle interface portion to the blade unit interface portion,

wherein ends of the first and second rigid protrusions are positioned facing each other in opposed spaced relation such that a longitudinal axis of the second rigid protrusion is generally collinear with a longitudinal axis of the first rigid protrusion.

10. The shaving system of claim 9 the return element comprises two spaced apart elastomeric members that extend in a direction generally perpendicular to a longitudinal axis of the blade unit, the shaving assembly comprises two first rigid protrusions and two second rigid protrusions, and one of the elastomeric members connects one of the first rigid protrusions to one of the second rigid protrusions and the other elastomeric member connects the other first rigid protrusion to the other second rigid protrusion.

11. The shaving system of claim 9 , 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.

12. The shaving system of claim 9 , wherein the return element is pretensioned.

13. The shaving system of claim 9 , wherein the return element comprises a thermoplastic elastomer or thermoplastic urethane.

14. The shaving system of claim 9 , wherein the return element includes two generally H-shaped portions.

15. The shaving system of claim 9 , wherein the rigid protrusions extend toward each other and are embedded in the return element.
