Abstract

The razor comprises a handle (1) and a removable head (3) which are coupled by means of a slide coupling. The handle and the head comprise each stop means (4, 5) which limit, when entering in contact with each other, the relative displacement between the handle and the head during their coupling in a position for which the head is centered on said handle and preventing any additional relative displacement in the same direction of said head and said handle.

Description

La présente invention sa rapporte à un rasoir mécanique à tête amovible par example tel que décrit dans la demande PCT WO 87/00113, les brevets US 4.612.704, 4.182.031, 4.272.886, 3.967.375, qui comprend un manche muni à l'une de ses extrémités d'une glissière permettant la fixation amovible d'une tête munie de lames de coupe qui comporte des organes correspondants aux dites glissières.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 at one of its ends of a slide allowing the removable fixing of a head provided with cutting blades which comprises members corresponding to said slides.

Dans les réalisations comme par exemple celle illustrée aux figures 1 et 2 du document WO 87/00113, le positionnement correct de la tête par rapport au manche en position de service est obtenu quasiment automatiquement. En effet, lorsque l'utilisateur enfile la glissière du manche latéralement dans les organes correspondants de la tête, située dans une boite, la position correcte est atteinte lorsque le manche en forme de T vient buter contre la paroi latérale de la boite contenant les têtes.In embodiments such as that illustrated in Figures 1 and 2 of WO 87/00113, the correct positioning of the head relative to the handle in the service position is obtained almost automatically. Indeed, when the user threads the slide of the handle laterally in the corresponding organs of the head, located in a box, the correct position is reached when the T-shaped handle abuts against the side wall of the box containing the heads .

Par contre, dès que le manche du rasoir ne présente plus la forme d'un T ou que les têtes amovibles ne sont plus contenues dans un présentoir assurant par sa paroi latérale la fixation en position corrects de service de cette tête sur le manche, l'utilisateur a grand peine à centrer la lame sur le manche. Il risque de plus en voulant corriger une mauvaise position de la tête de se couper les doigts puisqu'il doit saisir cette tête présentant les lames de coupe.On the other hand, as soon as the razor handle no longer has the shape of a T or that the removable heads are no longer contained in a display unit ensuring by its side wall the fixing in the correct service position of this head on the handle, the user has great difficulty in centering the blade on the handle. He also risks cutting his fingers by wanting to correct a bad position of the head since he must grasp this head with the cutting blades.

Le but de la présente invention est de remédier à cet inconvénient en réalisant un rasoir du type précité comportant des moyens permettant le positionnement automatique de la tête en position de service sur le manche.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.

Le rasoir selon la présente invention présente les caractéristiques décrites et revendiquées ci-après.The razor according to the present invention has the characteristics described and claimed below.

Le dessin annexé illustre schématiquement et à titre d'exemple plusieurs formes d'exécution du rasoir selon l'invention.The accompanying drawing illustrates schematically and by way of example several embodiments of the razor according to the invention.

Les figures 1 et 2 illustrent deux premières formes d'exécution du rasoir vu partiellement et en perspective.Figures 1 and 2 illustrate two first embodiments of the razor seen partially and in perspective.

Les figures 3 et 4 illustrent une troisième respectivement une quatrième forme d'exécution du rasoir vu en élévation partielle côté manche.Figures 3 and 4 illustrate a third respectively a fourth embodiment of the razor seen in partial elevation on the handle side.

La première forme d'exécution du rasoir mécanique à tête amovible illustrée à la figure 1 comporte un manche en forme générale de L présentant une tige de préhension 1 et une extrémité frontale 2 comportant la glissière à l'accoupler à la tête amovible 3, portant les lames de coupe, et munie des formations correspondantes aux glissières du manche pour sa fixation sur celui-ci.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 to couple it to the removable head 3, bearing the cutting blades, and provided with the formations corresponding to the guides of the handle for its fixing thereon.

L'extrémité frontale 2 du manche comporte une paroi 4 qui, lorsque la tête 3 est en position de service centrée sur la tige 1 du manche, bute contre la paroi terminale 5 de ladite tête 3 et fixe ainsi positivement cette position relative du manche et de la tête.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.

La tête 3 étant introduite et fixée dans la glissière de la partie frontale 2 du manche par un mouvement de gauche à droite suivant la flèche f, sa paroi frontale droite 5 vient buter contre la face interne de la paroi 4 de l'extrémité frontale 2 du manche interdisant tout déplacement relatif subséquent entre le manche et la tête dans ce sens et délimitant ainsi positivement et sans dépassement possible la position de service centrée de la tête sur le manche.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 according to 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.

Pour séparer la tête 3 du manche 1,2 il suffit à l'utilisateur de déplacer la tête 3 par rapport au manche 1,2 dans le sens contraire à la flèche f.To separate the head 3 from the handle 1,2, the user only has to move the head 3 relative to the handle 1,2 in the opposite direction to the arrow f.

Ce système d'arrêt ou de butée a également l'avantage, notamment par rapport à des dispositifs d'encliquetage à ressort qui ont été proposés, de ne pas être tributaire de la lubrification réalisée par la mousse à raser et de procurer toujours un positionnement exact et définitif.This stop or stop system also has the advantage, in particular with respect to spring snap devices which have been proposed, of not being dependent on the lubrication carried out by the shaving foam and of always providing a positioning exact and final.

Dans la seconde forme d'exécution illustrée à la figure 2 le manche présente également la forme générale d'un L, la tige 1 portant une partie frontale 2 munie de la glissière d'accouplement à une tête 3 munie de lames de coupe. La glissière de la partie frontale 2 coopère avec les formations ou tétons 6,6′6˝ correspondants pour la fixation de la tête 3 sur le manche 1,2. Ces tétons sont moulés avec la tête.In the second embodiment illustrated in FIG. 2, the handle also has the general shape of an L, the rod 1 carrying a front part 2 provided with the slide for coupling 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.

Dans cette exécution la partie droite de la glissière de l'extrémité frontale 2 du manche comporte une partie pleine 7 dont l'arête située en direction de la tige 1 du manche constitue une butée entrant en contact avec la tranche du téton 6 de la tête 3. La position de l'arête de la partie pleine 7 est définie de telle sorte que lorsqu'elle bute contre le téton 6 la tête 3 soit en position de service centrée sur la tige 1 du manche. Le fonctionnement de cette forme d'exécution est le même que celui de la première forme d'exécution, l'introduction de la tête 3 sur le manche 1,2 s'effectuant également par un déplacement de celle-ci suivant la flèche f.In this embodiment, 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 so 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.

Dans la troisième forme d'exécution, illustrée à la figure 3, le rasoir comporte un manche en forme de I étant 8 dont l'extrémité frontale comporte une glissière 9 coopérant avec des formations ou tétons correspondants 10 de la tête 3. Ici également la glissière 9 comporte une partie pleine 11 dont la face gauche vient, en position de service centrée de la tête 3, buter contre la face droite du téton 10 et constitue ainsi des moyens d'arrêt de la tête dans cette position centrée.In the third embodiment, illustrated in FIG. 3, the razor comprises an I-shaped handle being 8, the front end of which comprises a slide 9 cooperating with corresponding formations or nipples 10 of the head 3. Here also 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 stud 10 and thus constitutes means for stopping the head in this centered position.

Dans la forme d'exécution illustrée à la figure 4 le manche du rasoir présente la forme d'un I large 8 dont la partie frontale présente une glissière 9 coopérant avec des tétons 10, 10′, 10˝ de la tête 3. Ici également la partie droite de la glissière 9 est pleine et définit ainsi une butée 11 coopérant avec le têton 10 de la tête 3 pour limiter le déplacement relatif du manche 8 sur la tête 3 et définir positivement la position centrée de service de cette dernière.In the embodiment illustrated in Figure 4 the razor handle has the shape of a large I 8 whose front part has a slide 9 cooperating with pins 10, 10 ′, 10˝ of the head 3. Here also 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 the latter.

Des variantes de ce dispositif d'arrêt du déplacement de la tête sur le manche du rasoir peuvent être imaginées à l'infini, l'originalité de ce système résidant dans la fait quil y a blocage ou arrêt complet du mouvement relatif de la tête par rapport au manche du rasoir lorsque celle-ci atteint sa position centrée de service, cette position ne pouvant pas être dépassée. Il est donc impératif dans le rasoir selon l'invention que le retrait de la tête s'effectue par un mouvement relatif au manche suivant une direction opposée à celui servant à accoupler la tête au manche.Variations of this device for stopping the movement of the head on the handle of the razor can be imagined endlessly, the originality of this system lies in the fact that there is blocking or complete stopping of the relative movement of the head by relative to the razor handle when it reaches its centered service position, this position cannot be exceeded. It is therefore imperative in the razor according to the invention that the removal of the head is effected by a movement relative to the handle in a direction opposite to that used to couple the head to the handle.

Les moyens d'arrêt que le manche et la tête comportent et dont l'entrée en contact définit la position de service centrée de la tête sur le manche peuvent être apposés n'importe où sur le manche et la tête, pour autant que leurs positions soient telles qu'elles arrêtent le coulissement de la tête sur le manche lorsque celui-ci atteint sa position centrée de service. Plus particulièrement, notamment dans le cas des formes d'exécution dans lesquelles le manche présente la forme d'un I (figures 3 et 4), les moyens d'arrêt peuvent être également prévus de manière totalement indépendante des glissières.The stop means which the handle and the head comprise and whose contacting defines the centered service position of the head on the handle can be affixed anywhere on the handle and the head, provided that their positions are such that they stop the sliding of the head on the handle when the latter reaches its centered service position. More particularly, particularly in the case of embodiments in which the handle has the shape of an I (Figures 3 and 4), the stop means can also be provided completely independently of the slides.
