Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
83 words
A razor comprising a flexible blade package having one or more blade edges supported at each end as a fixed beam, a cooperating relatively rigid guard bar, said blade package and guard bar being positioned relative to one another to provide a given blade edge exposure, said blade package being operable in response to shaving forces to deflect relative to the guard to alter blade edge exposure, said guard bar being formed with a rod element effective to increase its resistance to bending.
Claim 2
Dependent Claim
83 words
A razor comprising a flexible blade package having one or more blade edges supported at each end as a fixed beam, a cooperating relatively rigid guard bar, said blade package and guard bar being positioned relative to one another to provide a given blade edge exposure, said blade package being operable in response to shaving forces to deflect relative to the guard to alter blade edge exposure, said guard bar being formed with a rod element effective to increase its resistance to bending.
Claim 3
Dependent Claim
81 words
A razor comprising a flexible blade package having one or more blade edges supported at each end as a fixed beam, a cooperating relatively rigid guard bar, said blade package and guard bar being positioned relative to one another to provide a given blade edge exposure, said blade package being operable in response to shaving forces to deflect relative to the guard to alter blade edge exposure, said guard bar being formed with a longitudinal notch to provide a hinge effect.
Claim 4
Dependent Claim
81 words
A razor comprising a flexible blade package having one or more blade edges supported at each end as a fixed beam, a cooperating relatively rigid guard bar, said blade package and guard bar being positioned relative to one another to provide a given blade edge exposure, said blade package being operable in response to shaving forces to deflect relative to the guard to alter blade edge exposure, said guard bar being formed with a longitudinal notch to provide a hinge effect.
Claim 5
Dependent Claim
24 words
The razor of claim 2 in which the guard bar is formed with an elongated rod element effective to increase its resistance to bending.
