Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A safety razor comprising a razor blade unit which is readily flexible, in response to forces encountered during normal use, about an axis or axes parallel with the plane of the blade and extending substantially perpendicular to the cutting edge of the blade, a handle and connecting means connecting the unit to the handle, the said connecting means comprising slide means for mounting and guiding the unit for reciprocal movement relative to the handle in a direction substantially perpendicular to the plane of the blade, the slide means being located at the mid-length of the unit, and further connections, to either side of the slide means, permitting relative movement of opposite end portions of the unit, relative to the handle in directions generally parallel to the blade edge.
Claim 2
Dependent Claim
128 words
A safety razor comprising a razor blade unit which is readily flexible, in response to forces encountered during normal use, about an axis or axes parallel with the plane of the blade and extending substantially perpendicular to the cutting edge of the blade, a handle and connecting means connecting the unit to the handle, the said connecting means comprising slide means for mounting and guiding the unit for reciprocal movement relative to the handle in a direction substantially perpendicular to the plane of the blade, the slide means being located at the mid-length of the unit, and further connections, to either side of the slide means, permitting relative movement of opposite end portions of the unit, relative to the handle in directions generally parallel to the blade edge.
Claim 3
Dependent Claim
31 words
A razor according to claim 1, wherein the said slide means comprises a post extending essentially perpendicular to the said plane and a socket in which the post is slidably engaged.
Claim 4
Dependent Claim
22 words
A razor according to claim 2, wherein the post and the socket are both of non-circular cross-section to prevent relative rotation therebetween.
Claim 5
Dependent Claim
31 words
A razor according to claim 2 or 3, wherein the said post is aligned with a central region of the unit in which the main forces encountered during shaving are directed.
Claim 6
Dependent Claim
52 words
A razor according to anyone of claims 1 to 4, wherein the said further connections each comprise a pin engaging in a socket with freedom to slide laterally therein, in directions generally parallel with the blade edge, but constrained against substantial relative movement in directions perpendicular to the plane of the blade.
Claim 7
Dependent Claim
36 words
A razor according to claim 5, wherein the pins extend parallel with the said axis or axes and have rounded upper and lower edges to facilitate flexure of the unit about the said axis or axes.
Claim 8
Dependent Claim
24 words
A razor according to claim 6, wherein the pins are fast with the razor handle and engage in pockets formed in the blade unit.
Claim 9
Dependent Claim
37 words
A razor according to any preceding claim, wherein the said further connections are each set in from the ends of the unit and are spaced apart by a distance approximately one-third of the length of the unit.
