Claims18

Dependent claims

A razor including a handle and a shaving head assembly connected to said handle, said shaving head assembly comprising

an elongated mounting plate fixed to said handle, said mounting plate having a top surface and being disposed symmetrically of said handle,
an elongated bridge member received on the top surface of said mounting plate for sliding travel longitudinally of said mounting plate between first and second positions thereon, and vice versa, said bridge member in its first position being disposed symmetrically of said handle and in its second position having one end and a longitudinal portion thereof extending beyond one end of said mounting plate,
a razor blade member received on top of said bridge member, and
a cap member received on top of said blade member, there being cooperating means on said blade member and said bridge member and cooperating means on said cap member and said bridge member for unitarily moving said blade member and said cap member with bridge member when said bridge member is slid between its first and second positions, said cap member having downwardly depending structure girdingly engaging longitudinal marginal portions of said mounting plate when said bridge member is in said first position, the underside of said bridge member and the upper surface of said mounting plate having cooperating structure engageable when said bridge member is in said first position for urging said bridge member upwardly of said mounting plate thereby to clamp said blade member against said cap member, the cooperating structure at said bridge member underside and said mounting plate upper surface disengaging when said bridge member is slid to its second position, the downwardly depending structure on said cap member being released from engagement with the marginal portions of said mounting plate when said bridge member is moved to its second position whereby said cap member can be lifted upwardly free of said assembly to permit removal and replacement of said blade member.
