Claim 5

An auxiliary trimmer head assembly as defined in claim 1 wherein said shaver housing comprises a head portion and a body portion, said trimmer blade assembly and said actuator member are mounted on said head portion, and wherein locking means are provided for locking said head portion to said body portion of said shaver.

Claim 6

In an electric shaver of the type having a housing, a power driven actuating member contained within said housing, and a cutter head of the close-shaving type including a multiapertured comb membeR and a cutter blade reciprocatively driven by said actuating member, an auxiliary head assembly comprising, in combination: a trimmer blade assembly comprising first and second trimmer blades having spaced cutting teeth at one end and arranged for relative reciprocation; means for pivotally mounting said trimmer blade assembly to said housing whereby said blade assembly is free to pivot between a retracted position, wherein said cutting teeth are disposed in close proximity to said comb member, and an extended position, wherein said cutter teeth project away from said housing; means comprising a cylindrical actuator surface on said first trimmer blade, said actuator surface including a cam track; an actuator cam operatively engaged with said cam track; and means comprising a user-actuable actuator button slidably mounted to said housing for driving said actuator cam along the surface of said actuator member parallel to said pivot axis to cause said trimmer blade assembly to pivot between said retracted and extended positions.

Claim 7

In an electric shaver of the type having a housing, a power driven actuating member contained within said housing, and a cutter head of the close-shaving type including a multiapertured comb membeR and a cutter blade reciprocatively driven by said actuating member, an auxiliary head assembly comprising, in combination: a trimmer blade assembly comprising first and second trimmer blades having spaced cutting teeth at one end and arranged for relative reciprocation; means for pivotally mounting said trimmer blade assembly to said housing whereby said blade assembly is free to pivot between a retracted position, wherein said cutting teeth are disposed in close proximity to said comb member, and an extended position, wherein said cutter teeth project away from said housing; means comprising a cylindrical actuator surface on said first trimmer blade, said actuator surface including a cam track; an actuator cam operatively engaged with said cam track; and means comprising a user-actuable actuator button slidably mounted to said housing for driving said actuator cam along the surface of said actuator member parallel to said pivot axis to cause said trimmer blade assembly to pivot between said retracted and extended positions.

Claim 8

An auxiliary head assembly as defined in claim 5 wherein said shaver housing comprises a head portion and a body portion, said trimmer blade assembly and said actuator member are mounted on said head portion, and wherein locking means are provided for locking said portion in position on said body portion of said shaver.

Claim 9

In an electric shaver of the type having a body housing and a power driven actuating member contained within said body housing, a combined close shaving and trimmer type head assembly comprising, in combination: a head assembly housing; a multi-apertured close-shaving comb member mounted to said head assembly housing; a close-shaving cutter blade assembly disposed within said head assembly housing in shearing engagement with the inside surface of said comb assembly, said cutter blade being operatively coupled to said actuating member; a trimmer blade assembly comprising first and second trimmer blades having spaced cutting teeth at one end and arranged for relative reciprocation; means for pivotally mounting said trimmer blade assembly to said head assembly housing whereby said blade assembly is free to pivot between a retracted position, wherein said cutting teeth are disposed in close proximity to said comb member, and an extended position, wherein said cutter teeth project away from said housing; means comprising a cylindrical actuator surface on said first trimmer blade, said actuator surface including a cam track; an actuator cam operatively engaged with said cam track; means comprising a user-actuable actuator button slidably mounted to said head assembly housing for driving said actuator cam along said cam track to cause said trimmer blade assembly to pivot between said retracted and extended positions; and latching means for removably mounting said head assembly housing to said body housing whereby in a closed position said cutter blade assembly is brought into shearing engagement with the inside surface of said comb assembly, and in an open position said cutter blade assembly is accessible for cleaning.

Claim 10

In an electric shaver of the type having a body housing and a power driven actuating member contained within said body housing, a combined close shaving and trimmer type head assembly comprising, in combination: a head assembly housing; a multi-apertured close-shaving comb member mounted to said head assembly housing; a close-shaving cutter blade assembly disposed within said head assembly housing in shearing engagement with the inside surface of said comb assembly, said cutter blade being operatively coupled to said actuating member; a trimmer blade assembly comprising first and second trimmer blades having spaced cutting teeth at one end and arranged for relative reciprocation; means for pivotally mounting said trimmer blade assembly to said head assembly housing whereby said blade assembly is free to pivot between a retracted position, wherein said cutting teeth are disposed in close proximity to said comb member, and an extended position, wherein said cutter teeth project away from said housing; means comprising a cylindrical actuator surface on said first trimmer blade, said actuator surface including a cam track; an actuator cam operatively engaged with said cam track; means comprising a user-actuable actuator button slidably mounted to said head assembly housing for driving said actuator cam along said cam track to cause said trimmer blade assembly to pivot between said retracted and extended positions; and latching means for removably mounting said head assembly housing to said body housing whereby in a closed position said cutter blade assembly is brought into shearing engagement with the inside surface of said comb assembly, and in an open position said cutter blade assembly is accessible for cleaning.
