ROLLING RAZOR AND SHAVING METHOD

Abstract: A razor handle (15,84,91), shaving system and shaving device (10,20,30,40,50,60,70,80,90,100), whereby precise finger-tip control of the pitch, angle and pressure applied by the fixed or replaceable shaving blades may be precisely controlled via the incremental movement of a ring shaped cylindrical handle.

Description: ROLLINGRAZORAND SHAVINGMETHOD BACKGROUND OF THE INVENTION Field Of The Invention: This present invention relates to a novel razor for shaving, and more particularly to a novel handle which provides for precise incremental rotational movement of the single or dual blades systems. This invention also provides a novel method of shaving resulting from the unique features of the rolling razor handle. Related Arts: Razors for shaving, both disposable razors and cartridge systems, are well known in the art. A commonality found in the prior art is the elongated handle, it may be wide, it may be narrow and it is often surfaced for better gripping, but the razor head, whether it be single, dual or triple blades is supported on an elongated substantially stick-like member such as those illustrated in U.S. Patents 4,026,016 issued to Nissen and 5,953,824 issued to Ferraro. Dual headed razors are found in the art. U.S. Patent 4,989,328 issued to Sokoloff, teaches a full sized blade coupled with a reduced size trimming blade, mounted opposite each other for easy access. The Sokoloff razor is not a bi-directional device. A push-pull bi-directional razor for shaving is described in U.S. Patent 5,865,189 issued to which has a pair of mirror image blades affixed to a stick handle and describes a method of pushing and pulling the blades against ones skin by moving the handle in one direction and then another. Pushing a razor blade at the end of a stick handle up and against ones face allows for bidirectional use, but may not have the stability of the normal shaving direction. Both the Nissen and Ferraro patents illustrate pivoting and swiveling shaving heads affixed to a stick-like handle to overcome the restrictions and limitations of blade positioning and movement, which arise trying to accommodate the changing contours of the human face and the changing growth patterns of facial hair using a razor on a stick handle razor. Finger tip gripping of a stick handle may allow for greater maneuverability but the trade-off is to limit control . SUMMARY OF INVENTION The within invention provides a ring shaped rotatable handle supporting one or more sets of blades and a method of shaving using bi-directional movement by rolling the handle around the forefinger, and adjusting the pitch and position of the blades with the thumb and middle finger on opposites of the ring shaped handle allows for bi-directional shaving with a continuous pulling action. By eliminating the "stick" handle and replacing it with the rolling ring handle the user becomes the pivot point and may control the system by using the sensitivity of their own fingers to adjust of the blades against the skin. This precise shaving system reduces cuts and nicks and enhances blade control. Additionally, the method yields precise pitch control, wherein the user may incrementally adjust the position of the blades, which makes facial, leg, underarm and whole head shaving simple and safe. The novel ring razor handle may be adapted to support a single set of blades for unidirectional use, or a dual set of opposing blades for bi-directional use. The device may be disposable or provide for replaceable blades. The handle also provides a novel replaceable blade cartridge. The features of the invention believed to be novel are set forth with particularity in the appended claim. The invention itself, however, both as to configuration, and method of operation, and the advantages thereof, may be best understood by reference to the following descriptions taken in conjunction with the accompanying drawings.

MODES FOR CARRYING OUT THE INVENTION Referring now to the drawings, there is illustrated in FIG. 1 A a perspective view of the rolling razor generally designated 10. This first embodiments a disposable razor for shaving. The non-replaceable shaving blades 11 are affixed to the front and back sides 12 & 13 of the bi-directional shaving head 14 which is connected to the ring shaped handle 15 with a short planar member forming a neck 16. Referring now to Figures IB, 1C and ID there is illustrated two side views and one front view of the method of operation of the preferred embodiment 10. A user will hold the rolling razor 10 in his hand 400 by inserting his index finger 401 inside the ring shaped handle 15. The thumb 402 and middle finger 403 rest against opposite sides of the outer surface of the ring-shaped handle 15 and are used to incrementally control the rotation of the bi-directional shaving head 14 in relation to the index finger 401, by rolling the ring shaped handle 15 with the thumb 402 and middle finger 403. Figure IB illustrates a downward stroke from neck 301 to chin 302 along the line of arrow 200. The downward stroke is a pulling stroke with the bi-directional shaving head 14 following the hand 400 and the blades 11 attached to the front side 12 of the bi-directional shaving head 14 are drawn against the beard. Figure 1C illustrates the return stroke which may occur without lifting the bi- directional shaving head 14 from the face 300. The return stroke along the line of arrow 201 is accomplished by completing the downward stroke and then incrementally rolling the H-directional shaving head 14 around the index finger 401, (with the help of the thumb 402 and middle finger 403 illustrated in figure ID), until the blades 11 affixed to the back side 13 are placed in contact with the face 300. The return stroke is shown from the chin 302 to neck 301 and is also a pulling stroke with the bi-directional shaving head 14 once again following the hand 400. It is envisioned that without departing from the intended scope of this invention, a plethora of blade and ring shaped handle configurations may be used as the support for a unidirectional or bi-directional shaving head and method. A critical feature of this invention is the incremental movement of the arched, or circular handle, with blades attached, around one or more fingers.
