Abstract
Description
L'invention concerne un procédé de fabrication de masques et/ou anti-vapeurs anti-poussière notamment, à partir d'au moins une feuille en matière filtrante. Corollairement, entrent dans le cadre de l'invention, les moyens de mise en oeuvre et les produits résultant du procédé. The invention relates to a method for manufacturing masks and / or anti-dust vapors in particular, from at least one sheet of filter material. As a corollary, within the scope of the invention, the means of implementation and the products resulting from the process.
L'objet de l'invention se rattache notamment au secteur technique des vêtements ou accessoires de protection et plus particulièrement les masques. The object of the invention relates in particular to the technical sector of protective clothing or accessories and more particularly masks.
Généralement, les masques de protection, notamment les masque: et anti-vapeurs anti-pouss er pro geant la bouche et le nez de l'utilisateur, sont réalisés par thermo-formage en ddìnissant une forme profilée pour s'adapter à la morphologie du visage. Le plus souvent, ils sont exécutés en matière ou matériau rigide ce qui necessite l'adjonction d'une bande souple montre en bordure du masque pour assurer l'étanchéité. De plus, ce caractère de rigidité ne permet pas de stocker facilement le masque et/ou de le conditionner dans un minimum de place en vue de sa commercialisation. Generally, the protective masks, in particular the anti-vapor and anti-vapor masks protecting the mouth and the nose of the user, are produced by thermoforming by defining a profiled shape to adapt to the morphology of the face. Most often, they are made of rigid material or material which requires the addition of a flexible band shown at the edge of the mask to ensure sealing. In addition, this rigidity does not allow the mask to be easily stored and / or packaged in a minimum of space for marketing.
Selon l'invention, on a réalisé un masque de protection d'une conception particulièrement simple et économique et parfaitement bien adapte pour remplir au maximum les fonctions qui lui sont demandes à savoir : protection et etanGhdité contre tous agents atmosphériques exterieurs. According to the invention, a protective mask has been produced with a particularly simple and economical design and perfectly suited to fulfill as much as possible the functions which are required of it, namely: protection and etanGhdity against all external atmospheric agents.
A cet effet, le masque est obtenu d partir d'au moins une feuille souple en matière ou matdriau ayant des capacités de fil tration. On plie en deux, dans le sens de la longueur, la feuille en matière filtrante, on effectue ensuite plusieurs pliages et assemblage de certaines parties de la feuille pour obtenir le corps du masque conforme pour s'appliquer d'une manière étanche sur la partie basse du visage, on équipe le masque de différents organes pour son adaptation et maintien sur le visages
Ces caractéristiques et d'autres encore ressortiront de la suite de la description.To this end, the mask is obtained from at least one flexible sheet of material or material having filtration capacities. The sheet of filter material is folded in half lengthwise, several folds are then made and some parts of the sheet are assembled to obtain the body of the mask in accordance with the invention, to be applied in a sealed manner to the part lower face, we equip the mask with different organs for its adaptation and maintenance on the faces
These characteristics and others will emerge from the following description.

La figure 18 est une vue en coupe transversale montrant un autre exemple de réalisation de la feuille filtrante à partir. de laquelle est réalisé le masque. Figure 18 is a cross-sectional view showing another embodiment of the filter sheet from. from which the mask is made.
Afin de rendre plus concret l'objet de l'invention, on le décrit d'une manière non limitative en se référant aux exemples de réalisation des figures des dessins. In order to make the object of the invention more concrete, it is described in a nonlimiting manner with reference to the exemplary embodiments of the figures of the drawings.
Le masque, désigné dans son ensemble par M, est obtenu à partir d'au moins une feuille 1 en matière ou matériau ayant des ca pacités de filtration et de pliage. D'une manière préférée, la feuille 1 est en mousse, fibre ou feutre carboné. The mask, designated as a whole by M, is obtained from at least one sheet 1 of material or material having ca pacities of filtration and folding. Preferably, the sheet 1 is made of foam, fiber or carbon felt.
Dans 1'F -emple des figures 2 à 8, la feuille 1 est tout d' abord pliée e deux dans le sens de la longueur. Les deux bords latéraux superposés il et 12 sont respectivement assemblés (figure 3) sur une partie de leur longueur. On rabat ensuite symé triquement, à partir de l'axe de pliure 1, les deux angles opposés 1 et 15 disposés d'un même côté qui viennent en superposition de la feuille. On voit qu'après le rabattement angulaire des 5 deux angles 1 et 1, les deux parties extrèmes 16 et 1 de l'axe de pliure 1, sont disposées en regard en étant sensiblement parallèles et juxtaposées.Ce rabattement angulaire laissé eggalement subsister à l'opposé de l'axe de pliure 13, deux bandes superposées 18 et 19 (figure 4). In the example of Figures 2 to 8, the sheet 1 is first folded in half lengthwise. The two lateral edges superimposed 11 and 12 are respectively assembled (FIG. 3) over part of their length. Then folded symmetrically, from the fold axis 1, the two opposite angles 1 and 15 arranged on the same side which come in superposition of the sheet. It can be seen that after the angular drawdown of the two angles 1 and 1, the two extreme parts 16 and 1 of the fold axis 1, are arranged facing each other while being substantially parallel and juxtaposed. This angular drawdown also allowed to remain at 'opposite the fold axis 13, two superimposed strips 18 and 19 (Figure 4).
4
Les deux angles rabattus 1 et 15 sont ensuite fixés sur la feuille 1.4
The two folded corners 1 and 15 are then fixed on the sheet 1.
Comme le montre la figure 5, on replie alors latéralement et on fixe sur elle-même, l'une des bandes libres 18 (figure 9), que l'on rabat de nouveau et que l'on fixe sur les angles rabattus et 15 (figures 6 et lO)o On opère de la même manière avec la bande libre 19 que l'on replie et quel'on fixe une première fois sur @;lle-mame et que l'on rabat et fixe ensuite sur la feuille 1 (figures 7 et 11). I1 suffit alors dcarter selon flèches F (figure 7) les bandes superposées et rabattues 18 et 19 pour obtenir le corps du masque M (figure 8) que l'on équipe d'une bride d'accrochage et de maintien 2 et d'une pince 3 faisant office de pince-nez. As shown in FIG. 5, one then folds laterally and fixes on itself, one of the free bands 18 (FIG. 9), which is folded down again and fixed on the folded corners and 15 (Figures 6 and 10) o We operate in the same way with the free band 19 which we fold and which we fix for the first time on @; lle-mame and which we fold and then fix on the sheet 1 (Figures 7 and 11). I1 then suffices to move aside according to arrows F (FIG. 7) the superimposed and folded bands 18 and 19 to obtain the body of the mask M (FIG. 8) which is fitted with a hooking and holding flange 2 and clip 3 acting as a nose clip.
Dans l'exemple des figures 12 a' 17, le masque est toujours obtenu à partir d'une feuille 4 en matière pu matériau ayant des capacités de filtration. Après pliage en deux de la feuille 4 dans le sens de la longueur (figure 12), on rabat latéralement du mAme cté, les extrémités ouvertes 41 et 42 (figure 13) que l'on fixe sur sur la feuille 4. On plie ensuite transversalement la feuille 4 sensiblement dans sa partie médiane 43 (figure 14) et l'on fixe ensemble les bords latéraux 44 et 45 ainsi obtenus, a l'opposé des parties rabattues 41 et 42 (figure 15)e Le corps du masque est ainsi réalisé.On peut également pratiquer une découpe 46 s'étendant du bord de pliage 43 aux bords assemblés 44 et 4 (figure 16). Comme dans la réalisation des figures 1 d 11, le masque est ensuite équipé en haut des extrémités ouvertes rabattues 49 et 42 de la feuille, d'une bride d'accrochage et de montant 5 et d'un organe 6 faisant office de pince nez. In the example of FIGS. 12 to 17, the mask is always obtained from a sheet 4 of material or material having filtration capacities. After folding the sheet 4 in half lengthwise (figure 12), the same side is folded laterally, the open ends 41 and 42 (figure 13) which are fixed on the sheet 4. Then folded transversely the sheet 4 substantially in its middle part 43 (FIG. 14) and the lateral edges 44 and 45 thus obtained are fixed together, opposite the folded parts 41 and 42 (FIG. 15) e The body of the mask is thus We can also make a cut 46 extending from the folding edge 43 to the assembled edges 44 and 4 (FIG. 16). As in the embodiment of FIGS. 1 to 11, the mask is then fitted at the top of the folded open ends 49 and 42 of the sheet, with a hooking flange and upright 5 and a member 6 acting as a nose clip .
Il faut considérer que l'assemblage et la fixation des diffé- rentes parties du corps du masque s'effectuent par tous tous moyens connus et appropriés, par exemple par couture, par collage, par soudure, ou. encore par l'adjonction de bandes adhésives double face, ou combinaison de ces différentes méthodes. It must be considered that the assembly and the fixing of the various parts of the body of the mask are carried out by any known and appropriate means, for example by sewing, by gluing, by welding, or. again by adding double-sided adhesive tapes, or a combination of these different methods.
On voit notamment aux figures 1, 8 et 17 que le procédé de pliage de la feuille en matière filtrante, laisse subsister un bourrelet E totalement on partiellement périphérique pour assu- rer l'étanchéité sur le visage et améliorer le confort de 15utili- sateur. It can be seen in particular in FIGS. 1, 8 and 17 that the method of folding the sheet of filtering material leaves a bead E totally or partially peripheral to ensure the seal on the face and improve the comfort of the user.
Il est également prévu de réaliser le masque au moyen de plusieurs feuilles de matéraux souples et en particulier, comme montez figure 18, une mousse carbonée 7 enserrée entre deux feuilles en matière filtrante 8 et 9. It is also planned to make the mask by means of several sheets of flexible materials and in particular, as shown in FIG. 18, a carbon foam 7 sandwiched between two sheets of filter material 8 and 9.
La bride de maintien et d'accrochage 2 ou 6 peut être fixée au masque en même temps ou après le pliage et l'assemblage de certaines parties constitutives du dit masque. The support and attachment flange 2 or 6 can be fixed to the mask at the same time or after folding and assembly of certain constituent parts of said mask.
Les avantages ressortent bien de la descritpion, en particulier on souligne et on rappelle - La simplicité de réalisation - La parfaite étanchéité sur le visage - Le confort de l'utilisateur - La légèreté - La facilité de stockage et de conditionnement, par simple pliage. The advantages emerge clearly from the description, in particular it is emphasized and recalled - The simplicity of production - The perfect seal on the face - The comfort of the user - The lightness - The ease of storage and packaging, by simple folding.
L'invention ne se limite aucunement à celui de ses modes d' application non plus quwà ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées t elle en embrasse-au contraire toutes les variantes. The invention is in no way limited to that of its modes of application, no more than to those of the embodiments of its various parts which have been more particularly indicated.
