Definitions

• the present invention relates to a mechanical razor with removable head for example as described in PCT application WO 87/00113, US patents 4,612,704, 4,182,031, 4,272,886, 3,967,375, which comprises a handle provided â at one of its ends of a slide allowing the removable fixing of a head provided with cutting blades which comprises organs corresponding to said slides.
• the object of the present invention is to remedy this drawback by producing a razor of the aforementioned type comprising means allowing the automatic positioning of the head in the service position on the handle.
• the razor according to the present invention has the characteristics described and claimed below.
• FIGs 1 and 2 it illustrate two first embodiments of the razor seen partially and in perspective.
• Figures 3 and 4 illustrate a third respectively a fourth embodiment of the razor seen in partial elevation on the handle side.
• the first embodiment of the mechanical razor with removable head illustrated in FIG. 1 comprises a handle in the general shape of an L having a gripping rod 1 and a front end 2 comprising the slide intended to couple it to the removable head 3, carrying the cutting blades, and provided with the formations corresponding to the guides of the handle for its fixing thereon.
• the front end 2 of the handle has a wall 4 which, when the head 3 is in the service position centered on the rod 1 of the handle, abuts against the end wall 5 of said head 3 and thus positively fixes this relative position of the handle and of the head.
• the head 3 being introduced and fixed in the slide of the front part 2 of the handle by a movement from left to right following the arrow f, its straight front wall 5 abuts against the internal face of the wall 4 of the front end 2 of the handle preventing any subsequent relative movement between the handle and the head in this direction and thus delimiting positively and without possible overshoot the centered service position of head on the handle.
• This stop or stop system also has the advantage, in particular with respect to spring-loaded locking devices which have been proposed, of not being dependent on the lubrication produced by the shaving foam and of always providing an exact and definitive positioning.
• the handle also has the general shape of an L, the rod 1 carrying a front part 2 provided with the coupling slide to a head 3 provided with cutting blades.
• the slide of the front part 2 cooperates with the corresponding formations or nipples 6.6 * 6 '' for fixing the head 3 on the handle 1, 2.
• These nipples are molded with the head.
• the straight part of the slide of the front end 2 of the handle has a solid part 7 whose edge located in the direction of the rod 1 of the handle constitutes a stop coming into contact with the edge of the stud 6 of the head. 3.
• the position of the edge of the solid part 7 is defined in such a way that when it abuts against the stud 6 the head 3 is in the service position centered on the rod 1 of the handle.
• the functioning of this embodiment is the same as that of the first embodiment, the introduction of the head 3 on the handle 1,2 also being effected by a displacement of the latter according to the arrow f.
• the razor comprises a narrow I-shaped handle 8, the front end of which comprises a slide 9 cooperating with corresponding formations or nipples 10 of the head 3.
• the slide 9 has a solid part 11, the left face of which comes, in the centered service position of the head 3, to abut against the right face of the pin 10 and thus constitutes means for stopping the head in this centered position.
• the razor handle has the shape of a wide I 8, the front part of which has a slide 9 cooperating with pins 10, 10 ′, 10 ′′ of the head 3.
• the right part of the slide 9 is full and thus defines a stop 11 cooperating with the pin 10 of the head 3 to limit the relative movement of the handle 8 on the head 3 and positively define the centered service position of this half era.
