Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
151 words
A wet shaving device having at least two single edge blades comprising a support element including a guard bar, a segmented flat blade spacer means hinged to the support element, said spacer means being grouped to define a first set of flat spacer segments and a second set of flat spacer segments, the spacer segments of the first set being disposed alternately with respect to the spacer segments of the second set, each spacer segment having a top side and a bottom side, a first blade fixed to the top side of the first set of flat spacer segments and a second blade fixed to the bottom side of the second set of spacer segments so that the first set of flat spacer segments and the first blade are free to pivot as a unit independently of the unit defined by the second set of spacer segments and the second blade.
Claim 2
Dependent Claim
151 words
A wet shaving device having at least two single edge blades comprising a support element including a guard bar, a segmented flat blade spacer means hinged to the support element, said spacer means being grouped to define a first set of flat spacer segments and a second set of flat spacer segments, the spacer segments of the first set being disposed alternately with respect to the spacer segments of the second set, each spacer segment having a top side and a bottom side, a first blade fixed to the top side of the first set of flat spacer segments and a second blade fixed to the bottom side of the second set of spacer segments so that the first set of flat spacer segments and the first blade are free to pivot as a unit independently of the unit defined by the second set of spacer segments and the second blade.
Claim 3
Dependent Claim
161 words
A wet shaving device having at least two single edge blades comprising a support element including a guard bar, a segmented flat blade spacer means hinged to the support element, said spacer means being grouped to define a first set of flat spacer segments and a second set of flat spacer segments, the spacer segments of the first set being disposed alternately with respect to the spacer segments of the second set, each spacer segment having a top side and a bottom side, a first blade fixed to the top side of the first set of flat spacer segments and a second blade fixed to the bottom side of the second set of spacer segments so that the first set of flat spacer segments and the first blade are free to pivot as a unit independently of the unit defined by the second set of spacer segments and the second blade, the pivoting of each blade-spacer unit being limited by stops.
Claim 4
Dependent Claim
161 words
A wet shaving device having at least two single edge blades comprising a support element including a guard bar, a segmented flat blade spacer means hinged to the support element, said spacer means being grouped to define a first set of flat spacer segments and a second set of flat spacer segments, the spacer segments of the first set being disposed alternately with respect to the spacer segments of the second set, each spacer segment having a top side and a bottom side, a first blade fixed to the top side of the first set of flat spacer segments and a second blade fixed to the bottom side of the second set of spacer segments so that the first set of flat spacer segments and the first blade are free to pivot as a unit independently of the unit defined by the second set of spacer segments and the second blade, the pivoting of each blade-spacer unit being limited by stops.
