Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a safety razor. 
     SUMMARY OF THE INVENTION 
     The razor of the invention comprises a head of a generally rectangular shape which has the cutting portion of a razor blade on at least one of its longitudinal sides and is characterized in that the head also has the cutting portion of a razor blade on at least one of its side edges. 
     In one embodiment of the invention, the blade arranged on the lateral side of the head is movable between two positions, in one position it projects from the head while in the other position it is retracted into the head. 
     According to another embodiment of the invention, the blade arranged to be movable on the side edge of the head comprises a control pin which projects from the head, two cavities being provided in the head to selectively receive a boss of the movable blade to immobilize it in the projecting position or in the retracted position.

     DETAILED DESCRIPTION OF THE INVENTION 
     The object of the present invention is to provide a safety razor which permits easy shaving operations in uneven regions of the face and especially in the region between the nose and the upper lip (e.g. base of the nose, openings of the nostrils) and also permits the cutting of the sideburns near the ears. 
     According to the invention, and referring to FIGS. 1-4, it is thus provided that the head of generally rectangular shape 1 of the razor comprises not only a blade of which the cutting edge (2) is arranged on one of its longitudinal sides but also a blade (3) which projects from lateral side (1 2 ) of that head. 
     Thus, bearing in mind the small dimensions of the width (1 2 ) and of the blade (3), the head (1) and the blade (3) can be readily positioned and oriented to cut into the base of the hairs at the end of the nostrils without the risk of the blade cutting the base of the nose. This arrangement also facilitates shaving operations all the way round any excrescences of flesh on the face and also in the region round the ears, especially sideburns. 
     Preferably, the small side blade (3) is curved as shown in FIG. 1 in order to permit accurate localization of the cutting region. 
     The blade (3), which is provided on one or both lateral sides of the head 1, can be moved between two positions in order to be placed in such a manner that it either projects from the head or is retracted into the interior of the head. 
     FIG. 2 shows the head of a safety razor of which the side blade (3) is molded onto the end of a body of plastic material (4) which is provided with a control pin (4 1 ) which projects from the upper longitudinal edge (1 3 ) of the head (1). 
     The body (4) is also provided with a curved boss (4 2 ) which can be received selectively in one of two adjacent cavities (5) provided inside the head (1) when the pin (4 1 )is actuated. This arrangement enables the blade (3) to be immobilized either in a position projecting from the head, in order to enable it to be used, or in a retracted position in order to prevent the risk of wounds, especially when the main blade (2) is being used for shaving. 
     According to the embodiment of FIGS. 1 and 2, the side blade 3 is independent of the longitudinal blade (2) but, if desired, and depending on the structure of the head of the safety razor, the blade (3) may be one and the same piece with the blade of which the cutting edge is arranged on one of the longitudinal sides (2 1 ) of the head (1). As shown, for example, in FIG. 1, the blade (3) extends outward the transverse side of the head of the razor. 
     FIGS. 3 and 4 show an embodiment of the invention in which the head (6) of a safety razor of which the shaving blade (7) has two parallel cutting edges (7 1 ) arranged along the longitudinal sides (6 1 )of the head, while the two side edges of that same blade (7) comprise rectilinear or curved extensions (7 2 ) which project from the lateral sides (6 2 )of the head. 
     In that case, the width of the extensions (7 2 ) may represent, for example, only one third or one quarter of the width (6 2 ) of the head, e.g. approximately 5 mm, in order to permit very localized shaving without the risk of causing wounds to neighboring regions. 
     According to the examples shown in FIGS. 3 and 4, the blade (7) provided with its side extensions (7 2 ) is fixed in position inside the head (6). 
     The blade (7), however, may also be movable longitudinally between two positions over a distance corresponding to the projecting portion of the extension (7 2 ) in order to be able to retract the extension into the head. In that case, of course, the extension (7 2 ) would be provided at only one end of the blade (7).
