Abstract

The hair brush has bristles (4) fitted into a supple membrane (3) which is semi-cylindrical in shape. The membrane is fitted on to a support (2) by two longitudinal pads (8), along each longitudinal edge, which slide in grooves (7) in the support and leave a cushion of air between the membrane and the support. The outer extremity of the membrane fits into a plug (5) with a stud (10) that engages in a blind hole (9) in the support. Longitudinal ribs (11) extend from the handle on the support to guide the membrane and ensure an airtight join.

Description

La présente invention a pour objet une brosse destinée en particulier mais non exclusivement au brossage des cheveux du type dit pneumatique. The present invention relates to a brush intended in particular but not exclusively for brushing hair of the so-called pneumatic type.

Dans les brosses de ce type, la partie brossante constituée par des poils ou picots a pour support une membrane en caoutchouc ou en matiere plastique souple. In brushes of this type, the brushing part constituted by bristles or pins has for support a rubber or flexible plastic membrane.

La membrane employée est de forme ovale ou rectangulaire et la monture comporte une rainure qui emprisonne la membrane sur tout son pourtour, la fixation se faisant par encliquetage ou collage. La membrane est elle-même de forme extérieure convexe de sorte qu'il subsiste après montage un coussin'd'air entre la membrane et la monture.The membrane used is of oval or rectangular shape and the frame has a groove which traps the membrane around its entire periphery, the fixing being done by snap-fastening or gluing. The diaphragm is itself of convex external shape so that after assembly there remains an air cushion between the diaphragm and the frame.

Par rapport aux brosses traditionnelles, les brosses pneumatiques présentent des avantages notables en ce que, notamment, la souplesse de la partie brossante permet d'utiliser des picots rigides métalliques ou moulés très pénétrants sans toutefois blesser le cuir chevelu
Malheureusement la structure plane de ces brosses ne permet pas de réaliser le brossage des cheveux sur toute leur longueur, ni leur bombage ce qui implique la nécessité de procéder à des mouvements semi rotatifs pour répondre aux exigences techniques des coiffures dites naturelles. On connaît, certes, par ailleurs, des brosses rondes ou demi-rondes mais, par leur structure même, elles présentent une liaison rigide ou au mieux semi-rigide entre la partie brossante et la monture.
Compared to traditional brushes, pneumatic brushes have notable advantages in that, in particular, the flexibility of the brushing part makes it possible to use rigid metal or molded pins very penetrating without however injuring the scalp
Unfortunately, the flat structure of these brushes does not make it possible to brush the hair over its entire length, or to curl it, which implies the need to carry out semi-rotary movements to meet the technical requirements of so-called natural hairstyles. It is known, of course, moreover, round or semi-round brushes but, by their very structure, they have a rigid or at best semi-rigid connection between the brushing part and the frame.

La présente invention a pour objet de remédier aux inconvénients des brosses connues et de simplifier la réalisation de coiffures naturelles modernes. The object of the present invention is to remedy the drawbacks of known brushes and to simplify the production of modern natural hairstyles.

Selon la présente invention, la brosse à cheveux comprenant un ensemble de poils ou picots sensiblement perpendiculaires à une membrane de caoutchouc solidarisée à sa périphérie avec une monture, un volume d'air étant interposé entre la monture et la membrane est caractérisée en ce que la membrane précitée est de forme sensiblement hémicylindrique. According to the present invention, the hairbrush comprising a set of bristles or pins substantially perpendicular to a rubber membrane secured to its periphery with a frame, a volume of air being interposed between the frame and the membrane is characterized in that the the aforementioned membrane is of substantially semi-cylindrical shape.

Selon une autre caractéristique de l'invention, la membrane est montée sur une monture présentant une section en arc de cercle par l'intermédiaire de deux bourrelets s'étendant le long de deux génératrices du cylindre enveloppant la partie brossante,coulissant dans des rainures de la monture. According to another characteristic of the invention, the membrane is mounted on a mount having a circular arc section by means of two beads extending along two generatrices of the cylinder enveloping the brushing part, sliding in grooves of Frame.

On obtient ainsi une brosse de:ni-ronde à coussin d'air qui réunit les -avantages des brosses pneumatiques connues et ceux des brosses rondes ou demi-rondes. There is thus obtained a brush: ni-round with air cushion which combines the advantages of known pneumatic brushes and those of round or semi-round brushes.

D'autres caractéristiques et avantages de l'invention apparaltront au cours de la description qui va suivre d'un mode de réalisation donné à titre d'exemple non limitatif, en regard des figures qui représentent
La figure 1, une vue d'une brosse selon l'invention, montée.
Other characteristics and advantages of the invention will appear during the description which follows of an embodiment given by way of nonlimiting example, with reference to the figures which represent
Figure 1, a view of a brush according to the invention, mounted.

La figure 2, une vue éclatée de la même brosse. Figure 2, an exploded view of the same brush.

La figure 3, une coupe selon la ligne III-III de la figure 1. Figure 3, a section along line III-III of Figure 1.

Sur la figure 1, la brosse se compose d'une monture comprenant un manche 1 de forme générale cylindrique se prolongeant par un support 2 destiné à recevoir la partie brossante qui se compose d'une membrane souple 3 en caoutchouc,par exemple, perpendiculairement à laquelle s'étendent des poils ou picots 4. La partie brossante est maintenue sur le support 2 par un bouchon 5. In FIG. 1, the brush consists of a frame comprising a handle 1 of generally cylindrical shape extending by a support 2 intended to receive the brushing part which consists of a flexible membrane 3 made of rubber, for example, perpendicular to which extend bristles or pins 4. The brushing part is held on the support 2 by a plug 5.

Comme cela apparaît mieux sur la figure 2, le support 2 présente en section la forme de secteur de cercle. La surface supérieure 6 est plane alors que la partie inférieure présente deux rainures 7 s'étendant sur toute la longueur de la partie support 2. Les rainures 7 sont destinées à recevoir des bourrelets 8 formés aux extrémités du demi-cylindre constitué par la membrane souple 3. La partie support 2 de la monture présente par ailleurs un trou borgne 9 destiné à recevoir et à encliqueter un ergot 10 formant projection à partir de la surface interne du bouchon 5.  As appears better in FIG. 2, the support 2 has in section the shape of a sector of a circle. The upper surface 6 is flat while the lower part has two grooves 7 extending over the entire length of the support part 2. The grooves 7 are intended to receive beads 8 formed at the ends of the half-cylinder formed by the flexible membrane 3. The support part 2 of the frame also has a blind hole 9 intended to receive and snap on a lug 10 forming a projection from the internal surface of the plug 5.

Enfin, le manche est réuni au support 2 par un ensemble de nervures 11 destinées à assurer la solidité de la liaison manche support. Finally, the handle is joined to the support 2 by a set of ribs 11 intended to ensure the solidity of the support handle connection.

On retrouve sur la figure 3 des éléments précédemment mentionnés et en particulier la partie support 2, le manche 1, les nervures 11. Les bourrelets 8 sont maintenus en position dans les rainures 7 du support 2. Les picots ou poils 4 sont emprisonnés dans la membrane souple par différents procédés connus et en particulier par moulage dans la membrane ou par entoilage. Comme cela apparaît sur la figure 3, le montage de la membrane 3 sur le support provoque la création d'une cavité 12 remplie d'air. L'air est maintenu dans la cavité 12 par contact sensiblement étanche d'une extrémité de la partie brossante 3 contre la virole 14 (figure 2) et de l'autre extrémité à l'intérieur du bouchon 5. De préférence, le bouchon 5 comprend un orifice 15 d'évacuation d'air.Dans la mesure où en vue de la qualité recherchée du brossage les picots sont rigides, il est indispensable que la surfacede support desdits picots soit souple. Cette souplesse est obtenue par coopératiqn de la membrane souple 3 et du coussin d'air de la cavité 12. Lorsque les efforts appliqués sur les picots sont faibles, la réaction auxdits efforts est assurée par la compression de l'air à l'intérieur de la cavité. Lorsque les efforts appliqués sont-plus importants, la pression à l'intérieur de la cavité augmente. Found in Figure 3 of the elements mentioned above and in particular the support part 2, the handle 1, the ribs 11. The beads 8 are held in position in the grooves 7 of the support 2. The pins or bristles 4 are trapped in the flexible membrane by various known methods and in particular by molding in the membrane or by interlining. As shown in Figure 3, the mounting of the membrane 3 on the support causes the creation of a cavity 12 filled with air. The air is maintained in the cavity 12 by substantially sealed contact at one end of the brushing part 3 against the ferrule 14 (FIG. 2) and at the other end inside the plug 5. Preferably, the plug 5 comprises an orifice 15 for evacuating air. Insofar as in view of the desired quality of the brushing the pins are rigid, it is essential that the support surface of said pins is flexible. This flexibility is obtained by cooperation of the flexible membrane 3 and the air cushion of the cavity 12. When the forces applied to the pins are low, the reaction to said forces is ensured by the compression of the air inside the cavity. When the applied forces are greater, the pressure inside the cavity increases.

et, afin de conserver la souplesse de la brosse on équilibre la pression interne et la pression atmosphérique en permettant l'évacuation d'une certaine quantité d'air par l'orifice 15 de sorte que la pression interne diminue.and, in order to maintain the flexibility of the brush, the internal pressure and the atmospheric pressure are balanced by allowing the evacuation of a certain amount of air through the orifice 15 so that the internal pressure decreases.

Dès que les efforts sont relâchés, la partie brossante reprend sa conformation initiale par pénétration d'air à travers l'ouverture 15. As soon as the forces are released, the brushing part resumes its initial conformation by air penetration through the opening 15.

Cette caractéristique permet la pénétration individuelle de chaque picot jusqu'à la base du cheveu, les picots adjacents au picot considéré présentant une inclinaison en fonction du contour extérieur de la tête.  This characteristic allows the individual penetration of each pin to the base of the hair, the pins adjacent to the pin considered having an inclination as a function of the external contour of the head.

On notera que la structure de cette brosse permet l'interchangeabIlité de la partie brossante, c'est ainsi que l'on peut par exemple remplacer un garnissage en poils de sanglier (pour lisser) par un garnissage à picots moulés destiné à donner du gonflant à la coiffure. La partie brossante et sa membrane de caoutchouc demeurent dans tous les cas parfaitement pneumatiques grâce au coussin d'air créé. It will be noted that the structure of this brush allows the interchangeabIlity of the brushing part, this is how one can for example replace a filling with boar bristles (to smooth) by a filling with molded spikes intended to give bulk to the hairstyle. The brushing part and its rubber membrane in all cases remain perfectly pneumatic thanks to the air cushion created.

Par ailleurs l'interchangeabilité de la partie brossante permet un nettoyage très facile.Furthermore, the interchangeability of the brushing part makes cleaning very easy.

Il va de soi que des modifications peuvent être apportées aux modes de réalisation qui viennent d'être décrits, notamment par substitution de moyens techniques équivalents, sans sortir pour cela du cadre de la présente invention.  It goes without saying that modifications can be made to the embodiments which have just been described, in particular by substitution of equivalent technical means, without departing from the scope of the present invention.
