BACKGROUND OF INVENTION The invention relates to shaving devices, and, more particularly, to an improved razor design for use in shaving concavely-contoured areas of the body.

Shaving armpits and other concavely-contoured areas of the body present problems when a conventional razor is used. For example, conventional, straight-edged razors are unable to follow the contour of the skin adequately in such areas. Moreover, such razors can produce unnecessary irritation since the ends of the blades will be forced against the skin more strongly than will the center portion. Straight-edged razors are also unable to follow the direction of beard growth in these areas. Such razors cut across, rather than along, the direction of beard growth, producing more irritation. It is known in the art to provide a blade having a single curve to facilitate shaving concavely-contoured areas. U.S. Patent No. 3,331,129, issued July 18, 1967, in the name of John S. Goudie, shows a razor curved about an axis perpendicular to the cutting edge and running through the center of the razor. However, this approach is not optimum for shaving concavely- contoured areas.

It is further known to provide a razor blade assembly which may be connected to, and used with, a handle to facilitate shaving. U.S. Patent No. 3,724,070, issued April 3, 1973, in the name of Francis . Dorion, Jr., shows a blade assembly in which the cutting element is held between surfaces designed to engage the area being shaved.

SUMMARY OF INVENTION 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. In the preferred embodiment, a handle is provided to support the razor and to facilitate shaving.

Because of the compound curvature of the razor, it will contact concave regions of the body more evenly for a better, less irritating shave. Moreover, the present invention will allow the shaver to follow the direction of beard growth in such areas.

BRIEF DESCRIPTION OF DRAWINGS 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.

PREFERRED EMBODIMENT Referring to 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.

In another embodiment, the curve about axis A-A., is imposed upon the blade when the handle is attached to the blade assembly.

In another embodiment, the convex curve of the cutting edge of the razor is flat in the center portion and curves convexly at the ends.
