Abstract
Abstract A razor blade assembly, in the form of a razor or shaving unit, comprises a top cap 114, a razor blade 113 fixed relative to the top cap, and a guardbar 115 which is pivotally movable relative to the blade from a shaving position, in which the blade is exposed for shaving, to a protecting position in which the guardbar prevents contact between the cutting edge of blade 113 and a user of the razor. The guardbar can be formed integrally with a platform 112 on which a second blade 123 is secured, or the second blade 123 could be secured to the top cap. In either case the guardbar and platform will pivot between the shaving position and the protecting position, and in latter position both blades will be protected.

Claim 1
Independent Claim
149 words
A razor blade assembly comprising a pair of blades each having a cutting edge; a guardbar; a top cap which covers a substantial portion of each blade and cooperates with the guardbar in locating the blade edges correctly with respect to the skin of a person shaving; and means mounting the guardbar for movement relative to the top cap from a position in which each blade edge is correctly exposed for shaving, to a position in which the guardbar screens each blade from contact with the person handling the blade assembly, said mounting means including a platform pivotable relative to said top cap and on which the guardbar is rigidly mounted, one of said blades being rigidly secured to the top cap and the other of said blades being rigidly secured to the platform, said blade edges being staggered with respect to each other when correctly exposed for shaving.
