Definitions

  • This invention relates to razors and is directed more particularly to safety razors provided with safety guard members.
  • Safety razors are generally provided with safety guard members which are disposed proximate to and parallel with the edges of blade supporting platforms whereby to underlie the cutting edge of a razor blade disposed upon a platform. Such guard members are frequently rigidly fixed to the head of the razor.
  • the pivotally mounted guard member offers some advantages in shaving
  • the Peck razor guard member has its pivot axis coincident with the blade cutting edge axis, so that pivotal movement of the guard member does not alter the exposure of the blade edge relative to he guard member, but merely changes the angle of the guard relative to the blade edge.
  • the Peck razor is somewhat awkward in structure and function and not readily acceptable by the market generally nor given to economical manufacturing.
  • a further object of the invention is to provide such a razor in which pivotal movement of the guard alters the exposure of the blades cutting edge relative to the guard.
  • a still further object of the invention is to provide such a pivot axis of the guard being removed from the nearest cutting I edge of the blade.
  • FIG. 1 is an exploded perspective view showing a portion of an illustrative razor embodying the features of the present invention
  • FIG. 2 is a perspective view
  • FIG. 3 is a top plan view
  • FIG. 4 is a bottom plan view of the head portion of the razor
  • FIG. 5 is a sectional view taken along line V-V of FIG. 3;
  • FIG. 6 is similar to FIG. 5 but shows the guard member pivotally disposed in a different position.
  • the illustrative razor includes a handle portion 2 adapted to be gripped by the hand of an operator.
  • a head portion 4 is mounted on one end of the handle portion 2 and includes a frame member 6 which is rigidly fixed to the handle 2.
  • a generally L-shaped blade support member 8 is fixed relative to the frame member 6, the frame member 6 and the blade support member 8 cooperating to receive and retain therebetween a blade B having a cutting edge E.
  • the blade support member 8 is provided with stop members l0, 12 which engage the edge E of the blade B and serve to properly locate the blade edge in the razor.
  • the blade support member 8 is provided on either side with lugs l4, 16 which serve to support by pivot pins 18, a guard member 20.
  • the guard member 20 comprises an elongated member which at a central portion 22 is curved, the curved portion being flanked by two generally planar portions, 24, 26.
  • the guard 20 is provided with an elongated slot 28 which is disposed proximate to and generally coextensive with the cutting edge E of the blade B.
  • the guard member 20 may be pivoted counterclockwise, as viewed in the drawings, until an enlarged portion 30 of the guard abuts a surface of the blade B. In such position, the blade edge E extends through the slot 28, slightly beyond the working surface 34 of the guard member.
  • FIG. 6 it will be noted that the guard is pivoted clockwise until the underside 36 of the guard abuts a projecting portion 32 of the lugs 14, 16 (lug 16 shown in FIG. 6). With the guard in the position shown in FIG. 6, the cutting edge E of the blade B extends into, but not through, the slot 28, the edge E being recessed somewhat beneath the exposed surface.
  • the guard is positioned by the angle at which the razor is disposed to a surface being shaved, rather than being rigidly locked into a permanent or preset position as is customary. Further, inasmuch as the pivot axis of the guard is removed from the blade edge, pivotal movement of the guard alters the exposure of the blade cutting edge relative to the guard, as illustrated in FIGS. 5 and 6.
  • the present invention is by no means limited to the particular construction herein disclosed and/or shown in the drawings, but also comprises any modifications or equivalents within the scope of the disclosure; for example, the pivot axis of the glard member may be located in various positions other than that shown, relative to the axis of the blade cutting edge, whereby to alter the exposure of the cutting edge.
  • a safety razor comprising a handle portion, a head portion mounted on one end of said handle portion, said head portion comprising a blade support means and a frame member for receiving and retaining a blade therebetween, and a guard member pivotally mounted on said head portion, said guard member having a pivot axis removed from a nearest cutting edge of a blade disposed in said razor, said guard member being provided with an elongated slot adapted to receive said cutting edge of said blade, said guard member being curbed about a lengthwise axis to provide a curved working surface disposed between two generally planar working surfaces.
  • a safety razor comprising a handle portion, a head portion mounted on said handle portion, said head portion comprising a blade support means and a frame member for receiving and retaining a blade therebetween, and a guard member mounted on said head portion for pivotal movement, said guard member being provided with an elongated slot adapted to receive said cutting edge of said blade, said guard member being curved about a lengthwise axis to provide a curved working surface disposed adjacent a generally planar working surface.
