Abstract

A wet shaver that includes a handle, a shaving head having at least two blades, defining a shaving plane (P), the shaving head having a cam surface, the shaving head being pivotally mounted on the handle about a pivot axis (X) parallel to the shaving plane, the shaving head having a rest position, a biasing member provided on the handle, adapted to exert a camming action on the cam surface to bias the shaving head toward the rest position.

First claim

We claim:

1. A wet shaver comprising:
a handle,
a shaving head (i) having at least two blades, (ii) defining a shaving plane, (iii) having a cam surface, (iv) being pivotally mounted on the handle about a pivot axis parallel to the shaving plane, and (v) operable to pivot between a rest position and a maximum elongated position, and
a biasing member (i) provided on the handle, (ii) adapted to exert a camming action on the cam surface to bias the shaving head toward the rest position and against a rest position abutment, thus forming a mono-directional pivoting razor allowing movement of the shaving head between the rest position and the maximum elongated position,
wherein at least a portion of the cam surface is substantially flat and substantially perpendicular to the shaving plane,
wherein the cam surface coincides with a cam plane that intersects the shaving plane at an intersection location, and
wherein the intersection location is in front of the blades.

2. The wet shaver according to claim 1 , wherein the cam surface is substantially parallel to the pivot axis.

3. The wet shaver according to claim 1 , wherein the biasing member is preloaded when the shaving head is in the rest position.

4. The wet shaver according to claim 1 , wherein the shaving head has a guard having a contact surface for contacting a user's skin and the intersection location is in the vicinity of the guard contact surface.

5. The wet shaver according to claim 1 , wherein the shaving head has a front side provided with the blades and a back side opposite to the front side, wherein the handle is provided with two symmetrically disposed arms each having a shell bearing at the end thereof, the biasing member being disposed between the two arms, and wherein the back side of the shaving head is provided with arcuate bearing surfaces cooperating with the shell bearings.

6. The wet shaver according to claim 5 , wherein the arcuate bearing surfaces are provided with at least one radial abutment cooperating with the shell bearing and adapted to form an angular stop position for the pivotal motion of the shaving head about the pivot axis.

7. The wet shaver according to claim 1 , and wherein the biasing member is an elastic tongue.

8. The wet shaver according to claim 7 , wherein the handle comprises a grip portion and a head portion, and wherein the elastic tongue is integral with the handle head portion.

9. The wet shaver according to claim 1 , wherein the shaving head has a front side provided with the blades and a back side opposite to the front side, the back side being provided with a middle rib, the cam surface being arranged on a cam member integral the middle rib.

10. The wet shaver according to claim 9 , wherein the middle rib has a width along the pivot axis, and the width is between 1.5 mm and 3.5 mm.

11. The wet shaver according to claim 9 , wherein the middle rib has a width along the pivot axis, and the width is less than 2 mm.

12. The wet shaver according to claim 1 , wherein the maximum elongated position is defined by an elongate position abutment.

13. The wet shaver according to claim 1 , wherein the maximum elongated position is defined by a plurality of elongate position abutments.

14. A wet shaver comprising:
a handle;
a shaving head (i) having at least two blades, (ii) defining a shaving plane, (iii) having a cam surface, (iv) being pivotally mounted on the handle about a pivot axis parallel to the shaving plane, and (v) having a rest position; and
a biasing member (i) provided on the handle, and (ii) adapted to exert a camming action on the cam surface to bias the shaving head toward the rest position,
wherein at least a portion of the cam surface is substantially flat and substantially perpendicular to the shaving plane,
wherein the cam surface coincides with a cam plane that intersects the shaving plane at an intersection location,
wherein the shaving head has a guard with a contact surface operable to contact a user's skin, and
wherein the intersection location is in front of the at least two blades and in a vicinity of the guard contact surface.

15. The wet shaver according to claim 1 , wherein the rest position is defined by a rest position abutment, wherein the shaving head is operable to pivot between the rest position and an elongated position, wherein the rest position is defined by at least one rest position abutment, wherein the elongated position is defined by at least one elongated position abutment.

16. A wet shaver comprising:
a handle;
a shaving head (i) having at least two blades, (ii) defining a shaving plane, (iii) having a cam surface, (iv) being pivotally mounted on the handle about a pivot axis parallel to the shaving plane, and (v) having a rest position; and
a biasing member (i) provided on the handle, and (ii) adapted to exert a camming action on the cam surface to bias the shaving head toward the rest position,
wherein at least a portion of the cam surface is substantially flat and substantially perpendicular to the shaving plane,
wherein the cam surface coincides with a cam plane that intersects the shaving plane at an intersection location,
wherein the intersection location is in front of the at least two blades,
wherein the shaving head has a front side provided with the at least two blades and a back side opposite to the front side, and
wherein the back side has a middle rib and the cam surface is arranged on a cam member integral to the middle rib.

17. The wet shaver according to claim 16 , wherein the middle rib has a width along the pivot axis, and the width is between 1.5 mm and 3.5 mm.

18. The wet shaver according to claim 16 , wherein the middle rib has a width along the pivot axis, and the width is less than 2 mm.

19. The wet shaver according to claim 16 , wherein the rest position is defined by a rest position abutment, wherein the shaving head is operable to pivot between the rest position and an elongated position, wherein the rest position is defined by at least one rest position abutment, wherein the elongated position is defined by at least one elongated position abutment.
