Definitions

  • the invention relates to shaving devices, and, more particularly, to an improved razor design for use in shaving concavely-contoured areas of the body.
  • the razor of the invention is curved about two separate axes.
  • the razor is defined by a thin structure of substantially parallel opposing surfaces having a cutting edge which is convexly curved. Additionally, the razor structure itself is curved about an axis along the razor surface extending perpendicularly from a plane tangent to the center of the cutting edge.
  • a handle is provided to support the razor and to facilitate shaving.
  • the present invention will allow the shaver to follow the direction of beard growth in such areas.
  • Fig. 1 is a perspective view of a razor embodying the present invention.
  • Fig. 2 is a perspective view of a preferred embodiment of the present invention.
  • Fig. 3 is a front view of the razor of Fig. 2.
  • Fig. 4 is a top view of the razor of Fig. 2.
  • Fig. 5 is an end view of the razor of Fig. 2.
  • Figs. 1, 2, 3, 4 and 5 there is shown a preferred embodiment of the invention designated generally 10.
  • the razor has a blade assembly 12 mounted on a handle 14.
  • a razor blade 16 has a cutting edge which is convexly curved as shown by Fig. 3.
  • the blade assembly 12 and hence the razor blade 16 are also curved about an axis A-A- as shown in Figs. 4 and 5.
  • the razor blade 16 is formed out of stainless steel or another similar material.
  • the blade assembly 12 and the handle 14 are formed out of one-piece plastic construction.
  • the curve about axis A-A. is imposed upon the blade when the handle is attached to the blade assembly.
  • the convex curve of the cutting edge of the razor is flat in the center portion and curves convexly at the ends.
