Abstract
Abstract The invention discloses a razor connector for affixing a razor handle (10) to a razor head (12) having a base (16) disposed on the razor handle. A pair of opposed upstanding spaced members (20) are attached to the base between the base ends and each member has a flange (24) for engagement with a bar (40) of the razor head. The connector also has a pair of outriggers (36) attached to each end of the base (16) and one outrigger is on each side of the opposed upstanding members (20). The connector also incorporates means for biasing the base (16) in a beam-like fashion so as to increase the gap between opposed upstanding members (20) distal the base, which allows release of the connection between the flanges (24) and the bar (40). The means for biasing the base can be a second pair of upstanding members (46), which are squeezed in an inwardly direction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
A razor connector for connecting a razor head to a razor handle, comprising: a base; a first pair of upstanding members attached to said base and having opposed vertical interior faces defining a centrally-disposed vertical gap therebetween; a pair of flanges, one attached to each of said opposed vertical interior faces adjacent a top of each face to project toward each other into said gap; a cavity in an outer surface of said razor head, for receiving at least a top portion of said first pair of upstanding members; a bar attached to said razor head across said cavity for protruding into said gap and being secured by said pair of flanges when said first pair of upstanding members is at least partially inserted into said cavity; and a second pair of upstanding members, connecting said base to said handle, for selectably applying a bending force to said base, and so for selectably increasing a distance between said flanges to cause said flanges to release said bar when said first pair of upstanding members is in said cavity.
Claim 2
Dependent Claim
178 words
A razor connector for connecting a razor head to a razor handle, comprising: a base; a first pair of upstanding members attached to said base and having opposed vertical interior faces defining a centrally-disposed vertical gap therebetween; a pair of flanges, one attached to each of said opposed vertical interior faces adjacent a top of each face to project toward each other into said gap; a cavity in an outer surface of said razor head, for receiving at least a top portion of said first pair of upstanding members; a bar attached to said razor head across said cavity for protruding into said gap and being secured by said pair of flanges when said first pair of upstanding members is at least partially inserted into said cavity; and a second pair of upstanding members, connecting said base to said handle, for selectably applying a bending force to said base, and so for selectably increasing a distance between said flanges to cause said flanges to release said bar when said first pair of upstanding members is in said cavity.
Claim 3
Dependent Claim
28 words
The connector as recited in claim 1 wherein said razor head bar has a tapered cross-sectional profile, the smallest width of said taper being proximate said outer surface.
Claim 4
Dependent Claim
48 words
The connector as recited in claim 1 wherein said flanges respectively comprise ends of said first pair of upstanding members distal said base, said member ends being beveled, in mutually opposed relationship, said beveled member ends defining a generally V-shaped notch adapted for receipt of said bar therebetween.
Claim 5
Dependent Claim
19 words
The connector as recited in claim 1 wherein said first pair of upstanding members has sidewalls defining thrust surfaces.
Claim 6
Dependent Claim
36 words
The connector as recited in claim 1 wherein said first pair of upstanding members define ledges proximate said base so as to limit insertion of said first pair of upstanding members into said razor head cavity.
Claim 7
Dependent Claim
44 words
The connector as recited in claim 5 wherein razor head outer surface defines a platform proximate said cavity for contact with said ledges on first pair of upstanding members when said first pair of upstanding members is fully inserted into said razor head cavity.
Claim 8
Dependent Claim
71 words
The connector as recited in claim 6 wherein each of said second pair of upstanding members further comprises an upward extension outside of and together bracketting at least a bottom portion of said first pair of upstanding members, and wherein razor head outer surface defines webs, projecting therefrom, proximate said platform for contact with said upward extensions during insertion of said first pair of upstanding members into said razor head cavity.
Claim 9
Dependent Claim
35 words
The connector as recited in claim 1 wherein said first pair of upstanding members and said cavity define corresponding polygonal shapes so as to allow alignment and relative receipt therebetween in only one relative orientation.
