Razor head with variable shaving geometry

A razor head comprising:

• a blade support structure having a rearwardly disposed cap member and a forwardly disposed guard member;
• a blade having a sharpened edge;
• means for supporting said blade for pivotal rotation from a normal position to at least one position other than said normal position, said supporting means connected to said blade support structure and pivoting about an axis disposed in a region extending from an area directly below said blade edge to an area below and forwardly of said blade edge;
• a blade retainer disposed on the supporting means wherein said blade is affixed to said blade retainer;
• and
• means for biasing said supporting means to said normal position wherein said biasing means are connected to said blade support structure;
• wherein said supporting means comprise a cylindrical member connected to said blade support structure.

A razor head comprising:

• a blade support structure having a rearwardly disposed cap member and a forwardly disposed guard member;
• a blade having a sharpened edge;
• means for supporting said blade for pivotal rotation from a normal position to at least one position other than said normal position, said supporting means connected to said blade support structure and pivoting about an axis disposed in a region extending from an area directly below said blade edge to an area below and forwardly of said blade edge;
• a blade retainer disposed on the supporting means wherein said blade is affixed to said blade retainer;
• means for biasing said supporting means to said normal position wherein said biasing means are connected to said blade support structure;
• wherein said supporting means comprise a cylindrical member connected to said blade support structure;
• and
• wherein said cap member and said guard member are integrally formed as portions of a frame which is adapted to receive a base member comprising said biasing means.

A razor head comprising:

• a base member;
• a forwardly positioned guard member secured to said base member;
• at least one blade having a sharpened edge;
• at least one blade retainer wherein said blade is affixed to said blade retainer;
• a dynamic support system connected to said base member, wherein said dynamic support system comprises means for supporting said blade such that said blade is pivotal from a normal position, about an axis disposed in a region extending directly below said blade edge to an area below and forwardly of said blade edge;
• and
• means for biasing said supporting means to said normal position;
• wherein said means for supporting said blade includes at least one cylindrical support member which supports the at least one blade retainer and said cylindrical support member pivots to cause the blade to move along a predetermined arcuate path in response to forces exerted on said razor head during shaving.
