Pivoting razors
Replaceable shaving assemblies are disclosed that include a blade unit, an interface element configured to removably connect the blade unit to a handle, on which the blade unit is pivotably mounted, and an elastomeric element disposed between the blade unit and interface element. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems.
1. A shaving assembly comprising:
a blade unit including an elastomeric guard;
a handle interface element configured to connect the blade unit to a handle, the blade unit being pivotably mounted on the handle interface element; and
an elastomeric element disposed between the blade unit and the handle interface element;
wherein the handle interface element includes a pair of fingers extending in opposite directions, and the elastomeric element comprises a pair of loops that are formed integrally with the guard and are configured to receive the fingers.
2. The shaving assembly of claim 1 wherein the fingers extend in opposite directions.
3. The shaving assembly of claim 1 wherein the guard includes a pair of openings defining elongated elastomeric portions that, when stretched during assembly, form the loops.
4. The shaving assembly of claim 3 wherein the elongated elastomeric portions are generally planar until stretched.
5. The shaving assembly of claim 1 , wherein the elastomeric 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 1 , wherein the elastomeric element comprises a thermoplastic elastomer.
7. The shaving assembly of claim 1 , wherein the loops extend from the blade unit.
8. The shaving assembly of claim 1 further comprising a blade unit interface element interposed between the handle interface unit and the blade unit.
9. The shaving assembly of claim 8 wherein the elastomeric element is carried by the blade interface unit.
10. The shaving assembly of claim 8 wherein the blade interface element snaps onto the blade unit.
11. A shaving system comprising:
a handle having a distal end and a proximal end; and
a shaving assembly that includes a blade unit including an elastomeric guard, a handle interface element, the blade unit being pivotably mounted on the handle interface element, and an elastomeric element disposed between the blade unit and the handle interface element;
wherein the handle interface element includes a pair of fingers extending in opposite directions, and the elastomeric element comprises a pair of loops that are formed integrally with the guard and are configured to receive the fingers.
12. The shaving system of claim 11 wherein the fingers extend in opposite directions.
13. The shaving system of claim 11 wherein the guard includes a pair of openings defining elongated elastomeric portions that, when stretched during assembly, form the loops.
14. The shaving system of claim 13 wherein the elongated elastomeric portions are generally planar until stretched.
15. The shaving system of claim 11 , wherein the elastomeric 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.
16. The shaving system of claim 11 , wherein the elastomeric element comprises a thermoplastic elastomer.
17. The shaving system of claim 11 , wherein the loops extend from the blade unit.
18. The shaving system of claim 11 further comprising a blade unit interface element interposed between the handle interface unit and the blade unit.
19. The shaving system of claim 18 wherein the elastomeric element is carried by the blade interface unit.
20. The shaving system of claim 18 wherein the blade interface element snaps onto the blade unit.
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 shaving assembly that includes:
a blade unit including an elastomeric guard;
an interface element configured to connect the blade unit to a handle, the blade unit being pivotably mounted on the handle interface element; and
an elastomeric element disposed between the blade unit and the handle interface element;
wherein the handle interface element includes a pair of fingers extending in opposite directions, and the elastomeric element comprises a pair of loops that are formed integrally with the guard and are configured to receive the fingers.
