Abstract
A shaving razor having at least two independent blade assemblies coupled to substantially rigid linkages. The linkages each defining a pivot point between the two independent blade assemblies. A bridge spans between the linkages such that movement of the bridge causes pivoting about the pivot point enabling reciprocating motion of the blade assemblies where assemblies on opposite sides of the pivot point reciprocate in opposite directions.
Claims20
A shaving razor comprising:
- at least two blade assemblies including a first independent blade assembly and a second independent blade assembly, each blade assembly having at least one blade;
- a first and second substantially rigid linkages coupling together the first and second independent blade assemblies, the linkages each defining a pivot point between the first and the second independent blade assemblies;
- a bridge spanning between and coupled the first and second linkages, wherein movement of the bridge causes the linkages to pivot about the pivot points such that the first and second blade assemblies move in opposite lateral directions responsive to a force applied by an actuator.
A shaving razor comprising:
- a first blade assembly having a first razor blade with a first cutting edge, the first blade assembly displaceable along a first path substantially parallel to the first cutting edge:
- a second blade assembly having a second razor blade with a second cutting edge, the second blade assembly deployed to cut in a same direction as the first blade assembly and to be displaceable along a second path substantially parallel to the second cutting edge:
- a first linkage coupling together a first end of the first blade assembly with a first end of the second blade assembly:
- and
- a second linkage coupling together a second end of the first blade assembly with a second end of the second blade assembly:
- wherein the first and second linkages are configured such that a first displacement of the first blade assembly along the first path causes a second displacement of the second blade assembly along the second path, the second displacement being in the same direction as, but with a different amplitude from, the first displacement.
