Abstract

A safety razor having a retractable blade member. The safety razor has a platform integral with the handle portion of the razor and provided with a recess formed in the upper surface thereof, a blade support member movably received by the recess of the platform, a blade member provided with front cutting edge and secured to and supported by said blade support member so as to project forwardly from the latter, a cover member fixed to the platform and cooperating with the latter in movably holding therebetween the blade support member together with the blade member, and apparatus for moving the blade member between a first position where the cutting edge is fully retracted and disappears behind the cover member and a second position where the cutting edge is fully extended. The cover member and the platform cooperate with each other in defining therebetween an elongated opening through which the cutting edge is moved in and out as the blade supporting member is moved by the above-mentioned apparatus. When the blade supporting member is moved toward the first position, the shaved matters sticking to the cutting edge or its vicinity are scraped off by the peripheral edges of the elongated opening.

Dependent claims

A safety razor comprising, a platform member including a first blade wiping portion, a handle joined to said platform member, cutting means supported on said platform member and including a blade member having a longitudinal cutting edge, said cutting means being relatively movable with respect to said platform member to move said longitudinal cutting edge from a protracted shaving position to a retracted non-shaving position, and vice versa, said cutting means being supported on said platform member such that said blade member is in contact with said first wiping portion in the vicinity of said longitudinal cutting edge during movement of said cutting means, a cover member disposed over said cutting means to permit exposure of the longitudinal cutting edge of said blade member while otherwise confining said cutting means between said platform member and said cover member, said cover member including means for connecting said cover member to said platform member, and means for moving said cutting means and said longitudinal cutting edge from said protracted position wherein the longitudinal cutting edge is extended from between the cover member and the platform member for use during shaving, to said retracted position wherein the longitudinal cutting edge is not extended for shaving use, thereby enabling said first wiping portion to wipe said blade surface in the vicinity of said longitudinal cutting edge for removal of shaven material and wherein said longitudinal cutting edge is entirely disposed between said first blade wiping portion and said cover member so as to render said longitudinal cutting edge incapable of cutting when said moving means moves said longitudinal cutting edge to said retracted position.
