Abstract
Abstract A specific embodiment provides an adjustable safety razor comprising a guard structure hinged to a blade seat, and a manually operable slide. A recess and a rail slidably interconnect the slide member and the blade seat for guiding the slide member in a direction parallel to an axis defined by the hinging structure. Another recess and rail slidably interconnect the slide member and the guard structure in an angular direction with respect to the axis of the hinging structure for moving the guard structure about the axis of the hinging structure upon manual operation of the slide member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
150 words
An adjustable safety razor comprising: a. a blade seat member, b. at least one blade positioned on said blade seat member, said at least one blade comprising at least one cutting edge, c. an elongated guard structure parallelly spaced forwardly of said at least one cutting edge, d. means for hinging said guard structure to said blade seat member, said hinging means defining an axis parallel to said guard structure, e. a manually operable slide member, f. means slidably interconnecting said slide member and said blade seat member for guiding said slide member in a direction parallel to said axis, and g. means slidably interconnecting said slide member and said guard structure in an angular direction with respect to said axis for moving said guard structure about said axis to adjust said guard structure with respect to said at least one cutting edge upon manual operation of said slide member.
