Abstract
Abstract A razor blade assembly includes a base member with a guard member resiliently mounted on the front wall of the base member for movement toward and away from the base member. At least one blade is mounted on the base member and is resiliently biased toward the front wall by a spring. The blade is movable rearwardly against the action of the biasing spring in response to shaving forces, independently of the movement of the guard.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
119 words
A razor blade assembly including in combination: a base member having a substantially planer blade mounting surface and having a front wall; resilient mounting means attached to said base member; a guard member attached to said resilient mounting means for movement toward and away from the front wall of said base member; at lease one blade means mounted on the blade mounting surface of said base member for limited movement thereon parallel to the plane of said blade mounting surface; and resilient spring biasing means for biasing said blade means toward the front wall of said base member to a first predetermined position, said blade means movable in response to shaving forces rearwardly away from said first predetermined position.
Claim 2
Dependent Claim
119 words
A razor blade assembly including in combination: a base member having a substantially planer blade mounting surface and having a front wall; resilient mounting means attached to said base member; a guard member attached to said resilient mounting means for movement toward and away from the front wall of said base member; at lease one blade means mounted on the blade mounting surface of said base member for limited movement thereon parallel to the plane of said blade mounting surface; and resilient spring biasing means for biasing said blade means toward the front wall of said base member to a first predetermined position, said blade means movable in response to shaving forces rearwardly away from said first predetermined position.
Claim 3
Dependent Claim
20 words
The combination according to claim 1 wherein said resilient mounting means and said resilient spring biasing means comprise independent means.
Claim 4
Dependent Claim
32 words
The combination according to claim 2 further including means for maintaining the relative alignment of the front wall of said base member, the guard member and said blade means with one another.
Claim 5
Dependent Claim
39 words
The combination according to claim 3 wherein said means for maintaining alignment includes a cap with mounting posts extending downwardly therefrom, and wherein said base member and said blade means have corresponding apertures therein for receiving said mounting posts.
Claim 6
Dependent Claim
47 words
The combination according to claim 4 wherein said resilient mounting means is attached to the front wall of said base member and causes said guard member to move toward and away from said front wall in a plane parallel to the plane of said blade mounting surface.
Claim 7
Dependent Claim
24 words
The combination according to claim 5 wherein said base member, said resilient mounting means and said guard member are integrally formed with one another.
Claim 8
Dependent Claim
65 words
The combination according to claim 6 wherein said blade means comprises first and second blade means, each having a cutting edge, with a spacer between said first and second blade means, with the cutting edge of said second blade means spaced upwardly of the cutting edge of said first blade means by said spacer, and rearwardly of the cutting edge of said first blade means.
Claim 9
Dependent Claim
32 words
The combination according to claim 1 further including means for maintaining the relative alignment of the front wall of said base member, the guard member and said blade means with one another.
Claim 10
Dependent Claim
39 words
The combination according to claim 8 wherein said means for maintaining alignment includes a cap with mounting posts extending downwardly therefrom, and wherein said base member and said blade means have corresponding apertures therein for receiving said mounting posts.
Claim 11
Dependent Claim
131 words
A razor blade assembly including in combination: a base member having a substantially planer blade mounting surface and having a front wall; at least one blade means mounted on the blade mounting surface of said base member for limited movement thereon, parallel to the plane of said blade mounting surface; a cap with mounting posts extending downwardly therefrom, and wherein said base member and said blade means have corresponding apertures therein for receiving said mounting posts; and resilient spring biasing means integrally formed with said cap and extending downwardly from the rear thereof toward said base member for biasing said blade means toward the front wall of said base member to a first predetermined position, said blade means movable in response to shaving forces rearwardly away from said first predetermined position.
