Abstract
A razor head has blade members with straight front cutting edges which are mutually parallel and lie in a cutting plane. Imaginary median surfaces of the blade members are continuously curved from the cutting plane, from the cutting edges toward the rear edges. The razor has a handle with a pair of fork arms, the distal ends of which are connected to the head at positions adjacent the respective ends of the head. Each fork arm has a groove allowing pivoting of the distal end about a pivot axis parallel to the head axis. Each groove is filled with a resiliently deformable material which is deformed when a pivoting force is applied to the razor head during shaving and which restores the razor head to a normal position when the force is removed.
Claims21
A razor head including a plurality of blade members, each having a straight front cutting edge and a rear non-cutting edge, the cutting edges lying in a cutting plane, each blade member having an outer surface facing toward the cutting plane and an opposite inner surface, with an imaginary median surface mid-way between the outer and inner surfaces, the median surfaces of the blade members being continuously curved in the same sense away from the cutting plane, from the cutting edges to the rear edges, the blade members being spaced apart to allow passage of waste material between them from the cutting edges to the rear non-cutting edges, the head including front, rear, and side elements forming a frame defining an opening through which the cutting edges are accessible, the frame having a shaving surface toward which the cutting edges are directed and a reverse surface, opposite the shaving surface, toward which the rear non-cutting edges of the blades are directed, the opening extending from the shaving surface to the reverse surface.
