Shaving razor pivot lock

1. A shaving razor comprising:

a handle having a gripping portion extending along a longitudinal axis and a head;

a cartridge mounted to the handle, the cartridge having a shaving surface with at least one blade having a blade edge, and an opposing surface, the cartridge having a forward pivot position and a rearward pivot position relative to the handle;

a pivot locking mechanism positioned on the head of the handle, the pivot locking mechanism having a pusher member that slides toward and away from the cartridge between an engaged position and a disengaged position wherein the pusher member in the engaged position directly contacts the opposing surface of the cartridge forcing the cartridge in the forward pivot position preventing the cartridge from pivoting with respect to the handle, and the pusher member in the disengaged position is spaced apart from the opposing surface of the cartridge in the forward pivot position allowing the cartridge to pivot relative to the handle, wherein the pivot locking mechanism comprises a latch that locks the pusher member in the engaged position and the latch has an upper portion extending from a body of the latch that facilitates the latch pivoting to release the latch allowing the pusher member to slide to the disengaged position.

2. The shaving razor of claim 1 wherein the pusher member is biased in the disengaged position.

3. The shaving razor according to claim 1 wherein the pusher member in the disengaged position is spaced apart from the opposing surface of the cartridge in the rearward pivot position.

4. The shaving razor of claim 1 wherein the latch pivots relative to the pusher member.

5. The shaving razor of claim 1 wherein the pivot locking mechanism comprises a base member joined to the head, and the pusher member slidingly engages the base member.

6. The shaving razor of claim 5 wherein the base member has at least one sliding surface that engages a corresponding surface on the pusher member.

7. The shaving razor according to claim 5 wherein a biasing member and a lower portion of the latch are positioned within a slot of the base member.

8. The shaving razor according to claim 5 wherein the latch has an undercut that engages a first stop surface on the base member in the disengaged position and a second stop surface on the base member in the engaged position.

9. The shaving razor according to claim 1 wherein the pusher member has a distal end surface that is generally transverse to the head of the handle for receiving forces exerted by a user's thumb or finger.

10. The shaving razor according to claim 1 further comprising a cartridge biasing member spaced apart from the pusher member and contacts the opposing surface of the cartridge biasing the cartridge in the forward position.

11. A shaving razor comprising:

a handle having a gripping portion extending along a longitudinal axis and a head;

a cartridge mounted to the handle, the cartridge having a shaving surface with at least one blade having a blade edge, and an opposing surface, the cartridge having a forward pivot position and a rearward pivot position relative to the handle;

a pivot locking mechanism positioned on the head of the handle, the pivot locking mechanism having a pusher member that slides toward and away from the cartridge between an engaged position and a disengaged position wherein the pusher member in the engaged position directly contacts the opposing surface of the cartridge forcing the cartridge in the forward pivot position preventing the cartridge from pivoting with respect to the handle, and the pusher member in the disengaged position is spaced apart from the opposing surface of the cartridge in the forward pivot position allowing the cartridge to pivot relative to the handle, wherein the pusher member has a distal end surface that is generally transverse to the head of the handle for receiving forces exerted by a user's thumb or finger and the distal end surface has a width that is greater than a proximal end surface of the pusher member and in the engaged position the proximal end surface contacts the opposing surface of the cartridge in the forward pivot position.

12. The shaving razor according to claim 11 wherein the cartridge pivots about an axis generally transverse to the longitudinal axis of the gripping portion and generally parallel to the blade edge.

13. The shaving razor of claim 11 wherein the pivot locking mechanism comprises a latch that locks the pusher member in the engaged position, and the latch pivots relative to the pusher member.

14. The shaving razor of claim 13 wherein the pivot locking mechanism comprises a base member joined to the head, and the pusher member slidingly engages the base member.

15. The shaving razor of claim 14 wherein the base member has at least one sliding surface that engages a corresponding surface on the pusher member.

16. The shaving razor according to claim 14 wherein a biasing member and a lower portion of the latch are positioned within a slot of the base member.

17. The shaving razor according to claim 14 wherein the latch has an undercut that engages a first stop surface on the base member in the disengaged position and a second stop surface on the base member in the engaged position.

18. The shaving razor according to claim 14 further comprising a cartridge biasing member spaced apart from the pusher member and contacts the opposing surface of the cartridge biasing the cartridge in the forward pivot position.
