Abstract
Abstract A razor blade assembly is provided having a molded plastic body member with a guard member mounted thereon. The body member comprises wall structure defining a pair of slots for receiving a blade means, and forming a support means on which the blade means rests. The blade means comprises a pair of cantilever spring portions formed in the blade means got contacting the support means when the blade means is disposed for slidable movement in the slots whereby the blade means is resiliently mounted in the body member.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
186 words
A razor blade assembly comprising: a body member; blade means mounted on said body member for movement thereon, said blade means having a base portion with a spring means formed thereon and a cutter portion, said base portion and said cutter portion, said base portion and said cutter portion defining an obtuse angle therebetween; support means formed on said body member disposed for contact with said spring means for support of said spring means during movement of said blade means relative to said body member; said spring means comprising an elongated segment of said base portion provided by forming a laterally extending slotted opening in said base portion, said elongated segment formed such that a free end thereof extends laterally, and is cantilevered from said base portion and the lower edge thereof is aligned with the lower edge of said base portion; and said blade means being mounted in said razor blade assembly such that said elongated segment free end rests on said support means and said base portion lower edge is in spaced relation with said body member allowing movement relative to said body member.
Claim 2
Dependent Claim
186 words
A razor blade assembly comprising: a body member; blade means mounted on said body member for movement thereon, said blade means having a base portion with a spring means formed thereon and a cutter portion, said base portion and said cutter portion, said base portion and said cutter portion defining an obtuse angle therebetween; support means formed on said body member disposed for contact with said spring means for support of said spring means during movement of said blade means relative to said body member; said spring means comprising an elongated segment of said base portion provided by forming a laterally extending slotted opening in said base portion, said elongated segment formed such that a free end thereof extends laterally, and is cantilevered from said base portion and the lower edge thereof is aligned with the lower edge of said base portion; and said blade means being mounted in said razor blade assembly such that said elongated segment free end rests on said support means and said base portion lower edge is in spaced relation with said body member allowing movement relative to said body member.
Claim 3
Dependent Claim
65 words
A razor blade assembly as set forth in claim 1 wherein said blade means comprises first and second blade members, each of said blade members having a respective base portion with a spring means formed thereon and a cutter portion defining an obtuse angle therebetween whereby said first and second blade means are movable relative to said body member and movable relative to each other.
Claim 4
Dependent Claim
120 words
A razor blade assembly as set forth in claim 1 wherein said spring means comprises a second elongated segment of said base portion provided by forming a second laterally extending slotted opening in said base portion, each said elongated segment formed such that a free end thereof extends laterally, and is cantilevered from said base portion and the lower edge thereof is substantially in alignment with the lower edge of said base portion, said blade means being mounted in said razor blade assembly such that said free end of each of said elongated segments rests on said support means and said base portion lower edge is in spaced relation with said body member allowing movement relative to said body member.
Claim 5
Dependent Claim
36 words
A razor blade assembly as set forth in claim 1 wherein said support means comprises shelf structure formed in said body member having a surface facing said blade means and positioned for contacting said spring means.
Claim 6
Dependent Claim
34 words
A razor blade assembly as set forth in claim 3 wherein said slotted openings are each disposed at opposite sides of said base portion and said free ends extend outwardly from said base portion.
Claim 7
Dependent Claim
36 words
A razor blade assembly as set forth in claim 3 wherein said slotted openings are each disposed adjacent the center of said base portion and said free ends are in facing relation, one with the other.
Claim 8
Dependent Claim
42 words
A razor blade assembly as set forth in claim 3 wherein each said elongated segment has a depth dimension between said slotted opening and the lower edge thereof which is of less magnitude adjacent said base portion than at said free end.
Claim 9
Dependent Claim
28 words
A razor blade assembly as set forth in claim 1 wherein said body member is formed of molded plastic material and said blade means comprises a steel material.
Claim 10
Dependent Claim

A razor blade assembly as set forth in claim 2 wherein said support means comprises a pair of shelf structures, one for each of said blade members formed in said body member, each shelf structure having a surface facing its respective blade member and positioned for contacting a respective free end of one of said elongated segments.
Claim 11
Dependent Claim
40 words
A razor blade assembly as set forth in claim 9 wherein each of said slotted openings is disposed at an opposite side of a respective blade member base portion and said free ends thereof extend outwardly from said base portion.
Claim 12
Dependent Claim
42 words
A razor blade assembly as set forth in claim 10 wherein each said elongated segment has a depth dimension between said slotted opening and the lower edge thereof which is of less magnitude adjacent said base portion than at said free end.
Claim 13
Dependent Claim
99 words
A razor blade for use in a safety razor assembly comprising: a base portion with a spring means formed thereon and a cutter portion, said base portion and said cutter portion defining an obtuse angle therebetween, said spring means comprising a pair of elongated segments of said base portion provided by forming a pair of laterally extended slotted openings in said base portion, each said elongated segment formed such that a free end thereof extends laterally, and is cantilevered from said base portion and the lower edge thereof substantially is aligned with the lower edge of said base portion.
