Abstract

Abstract A safety razor for trimming beards and mustaches around their edges is disclosed. The present invention comprises a razor blade, a head for holding the razor blade, and a blade support all having complementary tapered ends which taper from an edge opposite the cutting edge to a point just above the end of the cutting edge. The tapered ends permit the user of the safety razor to trim his beard or mustache beneath his nostrils. The present invention optionally includes a retractable miniature safety razor which is movable from a first position where it is retracted behind the head to a second position where it is deployed above the head for use in trimming the area beneath the center of the user's nose.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 90 words
A safety razor for trimming mustaches and beards comprising: a head, blade, and support including complementary thin tapered ends extending from an upper edge to a point proximate a lower edge; a cutting edge of the blade projecting from the head parallel to spaced above and proximate the lower edge; and a miniature safety razor supported by a handle and movable between a first position wherein it is retracted into the head to a second position beyond deployed above the head for trimming beards and mustaches beneath the user's nose.
Claim 2
Dependent Claim 90 words
A safety razor for trimming mustaches and beards comprising: a head, blade, and support including complementary thin tapered ends extending from an upper edge to a point proximate a lower edge; a cutting edge of the blade projecting from the head parallel to spaced above and proximate the lower edge; and a miniature safety razor supported by a handle and movable between a first position wherein it is retracted into the head to a second position beyond deployed above the head for trimming beards and mustaches beneath the user's nose.
Claim 3
Dependent Claim 244 words
A safety razor including a handle for shaving an edge of beards and mustaches comprising: a pair of opposed plastic blade supporting bodies comprising an elongated member including a planar face engaging wall extending downward and outward at an angle to an axis of the handle, a bottom wall beginning at a lower edge of the face engaging wall and extending upward from a rear edge of the bottom wall and spaced from the axis of the handle a distance to meet an upper edge of the face engaging wall, a vertical end wall defining one end of the member and a thin tapered end wall slanting from a point along the upper edge spaced from a center of the member to the lower edge defining another end of the member; a blade imbedded in the plastic body, a cutting edge of the blade spaced up a distance and proximate the lower edge extending outward and downward from the face engaging wall and extending longitudinally from a point close to but short of the thin tapered end and the vertical end wall; a downward extending collar integral with and supporting the members in a spaced apart manner to define a longitudinal channel between the rear walls, a threaded aperture formed in a lower end of the collar, a through opening concentric with the threaded bore aperture communicating with the longitudinal channel; and the handle including a threaded end to threadingly engage the threaded aperture.
Claim 4
Dependent Claim 244 words
A safety razor including a handle for shaving an edge of beards and mustaches comprising: a pair of opposed plastic blade supporting bodies comprising an elongated member including a planar face engaging wall extending downward and outward at an angle to an axis of the handle, a bottom wall beginning at a lower edge of the face engaging wall and extending upward from a rear edge of the bottom wall and spaced from the axis of the handle a distance to meet an upper edge of the face engaging wall, a vertical end wall defining one end of the member and a thin tapered end wall slanting from a point along the upper edge spaced from a center of the member to the lower edge defining another end of the member; a blade imbedded in the plastic body, a cutting edge of the blade spaced up a distance and proximate the lower edge extending outward and downward from the face engaging wall and extending longitudinally from a point close to but short of the thin tapered end and the vertical end wall; a downward extending collar integral with and supporting the members in a spaced apart manner to define a longitudinal channel between the rear walls, a threaded aperture formed in a lower end of the collar, a through opening concentric with the threaded bore aperture communicating with the longitudinal channel; and the handle including a threaded end to threadingly engage the threaded aperture.
Claim 5
Dependent Claim 149 words
The safety razor of claim 2 further comprising: a central bore formed in the handle; a rod including a threaded end slidingly engaging the bore; a miniature razor including a miniature face engaging wall extending downward and outward from the rod, a bottom wall extending from a bottom edge of the miniature wall, a rear wall extending between the bottom wall and a top edge of the miniature face engaging wall, a pair of end walls defining the ends of the miniature razor, a threaded aperture formed in the bottom wall to threadingly engage the threaded end of the rod, and a miniature blade with a projecting cutting edge near the bottom edge; the miniature razor being movable from a first position wherein it is retracted into the channel to a second position wherein it is deployed above the blade supporting bodies and usable to trim beards and mustaches.
Claim 6
Dependent Claim 48 words
The safety razor of claim 3 further comprising: a slot formed longitudinally along the handle communicating with the bore; a projection formed on the rod aligned with the slot and slidingly movable therealong; and wherein movement of the projection within the slot defines the first and second positions.
Claim 7
Dependent Claim 216 words
A safety razor and handle for shaving an edge of beards and mustaches comprising: a blade support affixed to the handle comprising an elongated member including a planar face engaging surface disposed at a downward angle to a handle axis, a bottom surface beginning at a lower edge of the face engaging surface and extending upward toward the handle, a rear surface extending between the bottom surface and an upper edge of the face engaging surface, a pair of slanted end surfaces beginning at a point spaced from a center of the elongated member at the upper edge to a point spaced above the lower edge; a blade imbedded in the support member including a cutting edge projecting downward and outward from the face engaging surface and spaced above the lower edge; a longitudinal bore formed centrally along the handle; a longitudinal slot communicating with the bore; an elongated rod slidingly engaging the bore; a miniaturized razor integral with an upper end of the elongated rod; a radial projection extending outward from the elongated rod slidingly engaging the longitudinal slot; and wherein the miniaturized razor and rod are movable from a retracted position wherein the miniaturized razor is below the blade support to a deployed position wherein the miniaturized razor is extended above the blade support.
Claim 8
Dependent Claim 216 words
A safety razor and handle for shaving an edge of beards and mustaches comprising: a blade support affixed to the handle comprising an elongated member including a planar face engaging surface disposed at a downward angle to a handle axis, a bottom surface beginning at a lower edge of the face engaging surface and extending upward toward the handle, a rear surface extending between the bottom surface and an upper edge of the face engaging surface, a pair of slanted end surfaces beginning at a point spaced from a center of the elongated member at the upper edge to a point spaced above the lower edge; a blade imbedded in the support member including a cutting edge projecting downward and outward from the face engaging surface and spaced above the lower edge; a longitudinal bore formed centrally along the handle; a longitudinal slot communicating with the bore; an elongated rod slidingly engaging the bore; a miniaturized razor integral with an upper end of the elongated rod; a radial projection extending outward from the elongated rod slidingly engaging the longitudinal slot; and wherein the miniaturized razor and rod are movable from a retracted position wherein the miniaturized razor is below the blade support to a deployed position wherein the miniaturized razor is extended above the blade support.
