Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne le domaine des masques de protection, et plus particulièrement les masques anti-pollution.The present invention relates to the field of protective masks, and more particularly the anti-pollution masks.

ART ANTERIEURPRIOR ART

Les masques faciaux anti-pollution, tels que ceux utilisés par les cyclistes, motocyclistes ou piétons, commercialisés actuellement peuvent être classés en deux catégories principales.Facial anti-pollution masks, such as those used by cyclists, motorcyclists or pedestrians, currently marketed can be classified into two main categories.

Dans la première catégorie se trouvent les masques en forme générale de coque, composés d'un corps entièrement réalisé en matériau filtrant et de sangles de maintien autour des oreilles ou à l'arrière de la tête de l'utilisateur. De par sa conception simple, ce filtre est léger, mais n'est pas plaqué sur le visage de l'utilisateur. De plus il doit être changé régulièrement : soit le filtre avec ses sangles de maintien si celles-ci sont solidaires du filtre, soit uniquement le corps du filtre si les sangles sont amovibles. Dans ce dernier cas, il existe un risque que les sangles puissent être égarées ou perdues.In the first category are the masks in the general shape of the shell, consisting of a body entirely made of filter material and retaining straps around the ears or behind the head of the user. By its simple design, this filter is lightweight, but is not plated on the user's face. In addition it must be changed regularly: the filter with its support straps if they are integral with the filter, or only the filter body if the straps are removable. In the latter case, there is a risk that the straps may be lost or lost.

Pour que le filtre soit maintenu en place et davantage plaqué sur le visage de l'utilisateur ont été développés des masques comportant un porte-filtre et au moins un filtre intérieur ainsi qu'une ou plusieurs cartouches filtrantes. Concernant ces masques qui appartiennent à la deuxième catégorie, se pose le problème du maintien ou de la fixation du filtre et/ou des cartouches dans le porte-filtre. Dans certains de ces masques les cartouches sont formées d'un pourtour généralement cylindrique en matériau rigide qui est solidarisé au porte-filtre, parfois en maintenant simultanément le filtre tapissant intérieurement le porte-filtre. Ces parties rigides peuvent entrer en contact avec le visage de l'utilisateur et être à l'origine de frottements désagréables si le porte-filtre est plaqué sur son visage.For the filter to be held in place and further plated on the face of the user were developed masks comprising a filter holder and at least one inner filter and one or more filter cartridges. Regarding these masks belonging to the second category, there is the problem of maintaining or fixing the filter and / or cartridges in the filter holder. In some of these masks the cartridges are formed of a generally cylindrical periphery of rigid material which is secured to the filter holder, sometimes simultaneously maintaining the filter lining internally the filter holder. These rigid parts can come into contact with the face of the user and cause unpleasant friction if the filter holder is pressed on his face.

On connaît de WO 2008/097379 un porte-filtre qui comporte notamment un anneau d'attache du filtre, ledit anneau étant logé dans une rainure ménagée à la périphérie du filtre à air.We know WO 2008/097379 a filter holder which comprises in particular a filter attachment ring, said ring being housed in a groove formed at the periphery of the air filter.

Pour les masques qui ne comportent pas de cartouche(s) filtrante(s), divers dispositifs d'attache ont été proposés, tels que des pinces, ou bouton-pression, ou encore des attaches de type Velcro® (bandes auto-agrippantes). Dans tous les cas, il s'agit d'éléments rapportés, soit directement sur le filtre (bouton-pression ou Velcro®), complexifiant ainsi sa fabrication, et donc son coût, soit indirectement, c'est-à-dire d'éléments d'attache amovibles, augmentant le risque de perte de ces éléments, lors du changement du filtre par exemple.For masks that do not have filter cartridge (s), various fastening devices have been proposed, such as clamps, or snap fasteners, or Velcro® type fasteners (Velcro strips) . In all cases, these are elements reported, either directly on the filter (snap or Velcro®), thus making it more difficult to manufacture, and therefore its cost, either indirectly, that is to say removable fastening elements, increasing the risk of loss of these elements, when changing the filter for example.

BUTS DE L'INVENTIONGOALS OF THE INVENTION

Un premier but de l'invention est donc de pallier les inconvénients des masques précités et de proposer un masque de la seconde catégorie, simplifié, ne comportant pas d'éléments amovibles autres que le filtre proprement dit.A first object of the invention is therefore to overcome the disadvantages of the aforementioned masks and to provide a mask of the second category, simplified, having no removable elements other than the actual filter.

Un autre but de l'invention est de proposer un masque incorporant un filtre de structure simple, léger et économique, aisément adaptable à son porte-filtre.Another object of the invention is to provide a mask incorporating a filter structure simple, lightweight and economical, easily adaptable to its filter holder.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Ces buts sont atteints par le masque facial, de type masque anti-pollution, comprenant un porte-filtre et un filtre amovible interchangeable,

  • le porte-filtre étant sous la forme générale de coque comportant des passages d'air, présentant une face avant, dite face extérieure, et une face arrière, ou face intérieure de forme concave, apte à recouvrir (envelopper) le nez, la bouche et le menton de l'utilisateur, et comportant des parties latérales auxquelles sont attachées des sangles de maintien (autour de la tête de l'utilisateur)
  • le filtre étant positionné contre la face concave intérieure du porte-filtre, épousant de préférence la forme de ladite face concave du porte-filtre ;
selon l'invention ce masque est caractérisé en ce que les sangles de maintien du porte-filtre coopèrent avec ledit filtre pour son positionnement contre la face concave du porte-filtre, par passage de sangles du porte-filtre dans des ouvertures ménagées dans ledit filtre.These goals are achieved by the face mask, of the anti-pollution mask type, comprising a filter holder and an interchangeable removable filter,
  • the filter holder being in the general shape of shell having air passages, having a front face, said outer face, and a rear face, or inner face of concave shape, able to cover (wrap) the nose, the mouth and the chin of the user, and having side portions to which are attached holding straps (around the head of the user)
  • the filter being positioned against the inner concave face of the filter holder, preferably conforming to the shape of said concave face of the filter holder;
according to the invention this mask is characterized in that the holding straps of the filter holder cooperate with said filter for its positioning against the concave face of the filter holder, by passing straps of the filter holder into openings in said filter.

Ainsi, le placement et le maintien du filtre à l'intérieur de la partie concave du porte-filtre, en vis-à-vis desdits passages d'air, ne nécessite aucun élément de maintien ou d'accroche complémentaire, puisque ce sont lesdites sangles qui assurent cette fonction. Il n'y a donc pas de risque de perte d'éléments amovibles. La conception du masque en est également simplifiée.Thus, the placement and maintenance of the filter inside the concave portion of the filter holder, vis-à-vis said air passages, requires no additional holding or hooking element, since it is said straps that provide this function. There is therefore no risk of loss of removable elements. The design of the mask is also simplified.

Ceci n'exclut pas l'ajout optionnel d'élément(s) de maintien supplémentaire(s) dans certains cas.This does not exclude the optional addition of additional holding element (s) in some cases.

De manière avantageuse, le filtre présente une partie centrale et des prolongements latéraux, chaque prolongement latéral présentant au moins une ouverture de passage de sangle du porte-filtre.Advantageously, the filter has a central portion and lateral extensions, each lateral extension having at least one strap passage opening of the filter holder.

Ces ouvertures prévues dans le filtre, en forme d'ouïes latérales, ont pour rôle principal de permettre l'enfilage des sangles du porte-filtre au travers desdites ouvertures, puis le maintien du positionnement dudit filtre, à l'état monté dans le porte-filtre.These openings provided in the filter, in the form of side openings, have for main role to allow the threading of the straps of the filter holder through said openings, then the maintenance of the positioning of said filter, in the mounted state in the door -filtered.

Selon une première variante de réalisation, lesdites ouvertures de passage pour les sangles du porte-filtre peuvent être des ouvertures ménagées dans lesdits prolongements du filtre, se présentant sous la forme de fentes ou d'oeillets. Des ouvertures sous la forme d'oeillets sont préférées pour d'une part autoriser un coulissement plus facile des sangles lors de leur insertion, et d'autre part permettre une meilleure adaptation aux différentes morphologies des utilisateurs (angle nez-oreilles) et/ou aux variations éventuelles de positionnement des sangles autour de la tête.According to a first embodiment, said passage openings for the straps of the filter holder may be openings in said extensions of the filter, in the form of slots or eyelets. Openings in the form of eyelets are preferred to firstly allow easier sliding of the straps during their insertion, and secondly to allow better adaptation to the different morphologies of users (nose-ears angle) and / or possible variations in the positioning of the straps around the head.

Selon une seconde variante, lesdites ouvertures de passage pour les sangles du porte-filtre peuvent être sous la forme de boucles, ou brides, solidaires des prolongements latéraux dudit filtre, par exemple solidarisées aux bords latéraux dudit filtre.According to a second variant, said passage openings for the straps of the filter holder may be in the form of loops, or flanges, secured to the lateral extensions of said filter, for example secured to the lateral edges of said filter.

De manière avantageuse, les prolongements latéraux du filtre sont formés d'un matériau renforcé par rapport à la partie centrale du filtre, de préférence par repli du matériau constitutif du filtre. Le filtre peut ainsi être fabriqué en un matériau unique, sans ajout de matière différente du matériau filtrant proprement dit.Advantageously, the lateral extensions of the filter are formed of a reinforced material relative to the central part of the filter, preferably by folding of the constituent material of the filter. The filter can thus be made of a single material without the addition of any material different from the actual filter material.

Les sangles sont de préférence fixées au porte-filtre par soudure ou couture, évitant ainsi toute perte des sangles. Seul le filtre est amovible. Ces sangles sont de préférence en matériau élastique.The straps are preferably attached to the filter holder by welding or stitching, thus avoiding any loss of the straps. Only the filter is removable. These straps are preferably made of elastic material.

Pour une meilleure étanchéité du masque, le porte-filtre peut comporter, dans sa partie supérieure, un élément comportant une partie métallique formant pince nasale, ledit élément formant pince nasale étant de préférence inséré entre les faces extérieure et intérieure dudit porte-filtre. Un tel dispositif permet également de limiter l'apparition de buée lorsque l'utilisateur porte des lunettes.For a better seal of the mask, the filter holder may comprise, in its upper part, an element comprising a metal part forming a nasal clamp, said nasal clamp member being preferably inserted between the outer and inner faces of said filter holder. Such a device also limits the appearance of mist when the user wears glasses.

Le porte-filtre comprend avantageusement une partie centrale de passage de l'air de respiration. Il peut s'agir d'un orifice central plus ou moins large, ou bien d'une zone centrale formée d'un matériau alvéolaire ou d'un matériau en fibres tissées ou non-tissées.The filter holder advantageously comprises a central portion for passage of the breathing air. It may be a more or less wide central orifice, or a central zone formed of a cellular material or a woven or non-woven fiber material.

Autour de ladite partie centrale, le porte-filtre peut comporter une partie périphérique en matériau souple, de référence en matériau extensible, tel qu'en caoutchouc ou de type néoprène, permettant l'adaptation et le plaquage du porte-filtre sur le visage de l'utilisateur, ladite partie périphérique comportant éventuellement des orifices de ventilation.Around said central portion, the filter holder may comprise a peripheral portion of flexible material, reference extensible material, such as rubber or neoprene, allowing the adaptation and the plating of the filter holder on the face of the user, said peripheral portion optionally having ventilation holes.

En ce qui concerne le filtre, il peut être réalisé en une ou plusieurs couches de matériau en fibres non-tissées. Par exemple il peut être composé d'une ou plusieurs couches d'un matériau non-tissé dénommé « meltblown », pour la fonction filtration de l'air pollué, inséré dans une enveloppe également réalisée en matériau non-tissé dénommé « spunbond ».As regards the filter, it may be made of one or more layers of nonwoven fiber material. For example, it may be composed of one or more layers of a non-woven material called "meltblown", for the filtration function of polluted air, inserted in an envelope also made of non-woven material called "spunbond".

Le masque selon l'invention permet d'utiliser dans le porte-filtre un filtre en matériau très léger et mince (ce qui est d'un grand confort pour l'utilisateur) tout en évitant les tensions sur ce matériau, et donc sans risque de déchirement (pouvant survenir avec des filtres nécessitant des éléments de maintien rigides tels que pinces, crochets, fermeture pression...).The mask according to the invention allows to use in the filter holder a filter very light and thin material (which is of great comfort for the user) while avoiding tensions on this material, and therefore without risk tearing (can occur with filters requiring rigid holding elements such as clamps, hooks, closing pressure ...).

Le masque facial selon l'invention est principalement destiné aux cyclistes, motocyclistes ou piétons avec pour objectif de les protéger de la pollution atmosphérique lors de leurs déplacements, mais peut également, avec un filtre de nature appropriée, être porté par d'autres catégories d'utilisateurs, dans un contexte professionnel par exemple.The facial mask according to the invention is mainly intended for cyclists, motorcyclists or pedestrians with the objective of protecting them from atmospheric pollution during their movements, but may also, with a filter of appropriate nature, be worn by other categories of people. users, in a professional context for example.

EXEMPLEEXAMPLE

Comme schématisé sur les figures 1 et 2, le masque 1 selon l'invention présente la forme générale d'une coque et est destiné à être disposé sur le visage d'un utilisateur 20 en enveloppant son nez, sa bouche et son menton, ainsi qu'une partie de ses joues et en étant retenu à l'arrière de sa tête par des sangles 8.As schematized on Figures 1 and 2 , the mask 1 according to the invention has the general shape of a shell and is intended to be placed on the face of a user 20 by wrapping his nose, mouth and chin, as well as part of his cheeks and by being restrained at the back of his head by straps 8.

Ce masque se compose d'un porte-filtre 2 et un filtre 11 amovible, comme visible sur les figures 4 et 5.This mask consists of a filter holder 2 and a removable filter 11, as visible on the Figures 4 and 5 .

Ledit porte-filtre 2 comprend une partie centrale 3 entouré d'une partie périphérique 4. Dans l'exemple présenté ici, la partie centrale cache et protège le filtre 11, tout en permettant un passage aisé de l'air entrant ou sortant de la bouche et du nez de l'utilisateur 20. A cet effet cette partie centrale peut être sous la forme d'un matériau alvéolaire, d'un matériau en fibres tissées ou non-tissées. Il peut également jouer un rôle de pré-filtre, par exemple pour des poussières présentes dans l'air.Said filter holder 2 comprises a central portion 3 surrounded by a peripheral portion 4. In the example presented here, the central portion hides and protects the filter 11, while allowing easy passage of the air entering or leaving the 20. For this purpose this central portion may be in the form of a cellular material, a material of woven or non-woven fibers. It can also act as a pre-filter, for example for dust present in the air.

La partie périphérique 4 du porte-filtre constitue ici en quelque sorte le squelette dudit porte-filtre, en supportant la partie centrale, la pince 7 pour le nez ainsi que l'extrémité de fixation des sangles 8. Cette partie périphérique 4 est en matériau souple et extensible, par exemple en caoutchouc ou en néoprène, permettent de plaquer le masque 1 sur le visage de l'utilisateur. Elle comporte néanmoins une série de trous 6 de ventilation, communiquant directement avec le filtre 11 sous-jacent.The peripheral portion 4 of the filter holder here constitutes, in a way, the skeleton of said filter holder, supporting the central portion, the clamp 7 for the nose and the fastening end of the straps 8. This peripheral portion 4 is flexible and extensible material, for example rubber or neoprene, allow to press the mask 1 on the user's face. It nevertheless has a series of ventilation holes 6, communicating directly with the underlying filter 11.

Une première extrémité de chaque sangle est, dans l'exemple présenté aux figures annexées, fixée à proximité d'un bord latéral de la partie périphérique 4 du porte-filtre 2, au moyen d'une couture 9. Les autres extrémités des sangles se rejoignent à l'arrière de la tête de l'utilisateur par l'intermédiaire d'une bande auto-agrippante 10.A first end of each strap is, in the example shown in the accompanying figures, fixed near a side edge of the peripheral portion 4 of the filter holder 2, by means of a seam 9. The other ends of the straps are join the back of the head of the user via a Velcro strip 10.

La pince nasale 7, de type pince-nez, comprenant un élément métallique est disposée en partie supérieure 5 de la partie périphérique du porte-filtre, entre les faces interne et externe du dit porte-filtre. La figure 2 montre son emplacement avec la partie supérieure ouverte (cette pince 7 n'est pas visible à l'état normal : voir figure 3).The nose clip 7, of the nose clip type, comprising a metal element is disposed in the upper portion 5 of the peripheral portion of the filter holder, between the inner and outer faces of said filter holder. The figure 2 shows its location with the upper part open (this clamp 7 is not visible in the normal state: see figure 3 ).

Le filtre 11 présente également la forme générale d'une coque de manière à épouser la forme de la face interne concave du porte-filtre 2. Ce filtre se compose d'un corps 17 et de deux prolongements latéraux 18 dans lesquels sont ménagés des ouvertures 12 en forme d'oeillets, par exemple de forme circulaire comme schématisé sur les figures 4, 5, 6 et 7. Ces ouvertures servent au passage des sangles 8, enfilées suivant les flèches F de la figure 4. Le diamètre de ces ouvertures 12 est de préférence légèrement supérieur à la largeur desdites sangles 8.The filter 11 also has the general shape of a shell so as to conform to the shape of the concave internal face of the filter holder 2. This filter consists of a body 17 and two lateral extensions 18 in which openings are formed. 12 in the form of eyelets, for example of circular shape as schematically on the Figures 4, 5 , 6 and 7 . These openings are used for the passage of the straps 8, threaded according to the arrows F of the figure 4 . The diameter of these openings 12 is preferably slightly greater than the width of said straps 8.

Ainsi le filtre 11 est aisément positionné contre la face concave du porte-filtre 2, comme visible sur la figure 5.Thus the filter 11 is easily positioned against the concave face of the filter holder 2, as visible on the figure 5 .
