Description

PROCEDE DE TRAITEMENT SANITAIRE D'UN MATELAS DE COUCHAGE ET DISPOSITIF ASSOCIE METHOD FOR THE SANITARY TREATMENT OF A SLEEPING MATTRESS AND ASSOCIATED DEVICE
La présente invention a pour objet un procédé de traitement sanitaire d'un matelas de couchage, notamment un matelas à ressorts, et un dispositif qui permet de mettre en oeuvre ledit procédé.The subject of the present invention is a method of sanitary treatment of a sleeping mattress, in particular a spring mattress, and a device which makes it possible to implement said method.
Les matelas, notamment les matelas à ressorts, sont des lieux où la prolifération des bactéries et des acariens est favorisée par la température et l'humidité, l'espace interne libre étant souvent poussiéreux et propice à la prolifération de ces parasites. Ces matelas peuvent être impliqués dans les problèmes d'allergies qui provoquent chez les personnes qui y sont sensibles des problèmes médicaux importants. Aussi, il convient de traiter les matelas avec des produits acaricides et bactéricides afin de limiter le développement des acariens et des bactéries et donc de limiter les problèmes des personnes qui y sont sensibles.Mattresses, especially spring mattresses, are places where the proliferation of bacteria and mites is favored by temperature and humidity, the internal free space is often dusty and conducive to the proliferation of these parasites. These mattresses can be involved in allergy problems that cause significant medical problems in people who are sensitive to them. Also, it is advisable to treat the mattresses with acaricides and bactericides in order to limit the development of mites and bacteria and therefore to limit the problems of people who are sensitive to them.
Par ailleurs, certains utilisateurs souhaitent disposer d'une chambre et d'un matelas ayant une odeur parfumée. Des matelas équipés de dispositifs de diffusion de produits pesticides et/ou odorants existent mais aucun dispositif ne donne pleinement satisfaction.In addition, some users wish to have a bedroom and a mattress with a perfumed odor. Mattresses equipped with devices for diffusing pesticides and / or odors exist but no device is fully satisfactory.
Un premier exemple de dispositif est décrit dans le brevet français FR-A- 92.07870 au nom du demandeur, il est constitué d'une cassette, placée sur la tranche du matelas qui contient le produit à diffuser sous forme solide. L'air, circulant de l'extérieur du matelas vers l'intérieur, à travers un orifice, favorise la sublimation des produits solides pesticides et/ou odorants, en assurant un traitement en continu de l'intérieur du matelas.A first example of a device is described in French patent FR-A-92.07870 in the name of the applicant, it consists of a cassette, placed on the edge of the mattress which contains the product to be broadcast in solid form. The air, circulating from the outside of the mattress towards the inside, through an orifice, promotes the sublimation of solid pesticides and / or odorants, by ensuring a continuous treatment of the inside of the mattress.
Mais ce dispositif a un principal inconvénient. Le phénomène de sublimation est délicat à contrôler car il varie fortement en fonction des conditions de température et d'hygrométrie.But this device has a main drawback. The sublimation phenomenon is difficult to control because it varies greatly depending on the temperature and humidity conditions.
Un autre dispositif de l'art antérieur décrit dans le brevet français FR-A- 94.1 4408 au nom du demandeur, comprend des moyens d'injection sous pression d'un gaz de traitement contenu dans une bombe aérosol. Ce dispositif ne donne pas pleinement satisfaction sur deux points.Another device of the prior art described in French patent FR-A-94.1 4408 in the name of the applicant, comprises means for injecting under pressure a treatment gas contained in an aerosol can. This system is not fully satisfactory on two points.
D'une part, à chaque produit correspond une bombe aérosol dont le prix est relativement élevé. D'autre part, le gaz propulsé par la bombe peut se propager difficilement dans tout l'espace interne libre du matelas, ce qui peut nuire à l'efficacité du traitement. La présente invention vise à pallier ces problèmes en proposant un procédé qui permet un traitement sanitaire efficace dans la globalité de l'espace interne libre du matelas. Ce procédé permet également d'enlever la poussière et de renouveler l'air se trouvant dans l'espace interne libre du matelas. L'invention propose également un dispositif simple et efficace de mise en oeuvre dudit procédé.On the one hand, each product corresponds to an aerosol can whose price is relatively high. On the other hand, the gas propelled by the bomb can spread with difficulty throughout the free internal space of the mattress, which can affect the effectiveness of the treatment. The present invention aims to overcome these problems by proposing a method which allows effective sanitary treatment in the entirety of the free internal space of the mattress. This process also removes dust and renews the air in the free internal space of the mattress. The invention also provides a simple and effective device for implementing said method.
A cet effet, le procédé selon l'invention de traitement sanitaire du volume interne libre d'un matelas de couchage, notamment un matelas à ressorts, ledit matelas comprenant des faces supérieure et inférieure, une bande latérale périphérique, se caractérise en ce qu'il consiste à créer un flux d'air de l'extérieur vers l'espace interne libre du matelas, des agents actifs pesticides et/ou odorants étant préalablement, ou simultanément, diffusés à proximité du matelas.To this end, the method according to the invention for sanitary treatment of the free internal volume of a sleeping mattress, in particular a spring mattress, said mattress comprising upper and lower faces, a peripheral lateral band, is characterized in that it consists in creating an air flow from the outside to the free internal space of the mattress, pesticidal and / or odorous active agents being previously, or simultaneously, diffused near the mattress.
Selon un mode préférentiel de mise en oeuvre, le flux d'air de l'extérieur vers l'espace interne libre du matelas est engendré par une dépression dans l'espace interne libre, ladite dépression étant créée par un appareil d'aspiration raccordé au matelas à l'aide d'au moins un dispositif de raccordement, ledit appareil d'aspiration permettant également d'enlever la poussière et de renouveler l'air se trouvant dans l'espace interne libre.According to a preferred embodiment, the air flow from the outside to the free internal space of the mattress is generated by a vacuum in the free internal space, said vacuum being created by a suction device connected to the mattress using at least one connecting device, said suction device which also removes dust and replenishes the air in the internal free space.
De préférence, les agents actifs pesticides et/ou odorants sont diffusés par pulvérisation desdits agents actifs sous forme de fines particules à l'aide notamment d'une bombe aérosol ou d'un pulvérisateur.Preferably, the pesticidal and / or odorous active agents are diffused by spraying said active agents in the form of fine particles using in particular an aerosol can or a sprayer.
D'une autre manière, les agents actifs pesticides et/ou odorants sont diffusés par sublimation de produits solides contenant lesdits agents actifs, les produits solides étant placés à proximité du matelas, de préférence dans un dispositif de diffusion par sublimation. L'invention a également pour objet un dispositif de raccordement, notamment à un appareil d'aspiration comprenant un embout, servant à la mise en oeuvre dudit procédé, caractérisé en ce qu'il est réalisé par un manchon, disposé perpendiculairement sur la bande latérale périphérique du matelas, dont une première extrémité débouche dans l'espace interne libre et l'autre à l'extérieur du matelas, et qui comprend des moyens de liaison à ladite bande latérale, des moyens de raccord, notamment à l'appareil d'aspiration, ainsi que des moyens d'obturation.In another way, the pesticidal and / or odorous active agents are diffused by sublimation of solid products containing said active agents, the solid products being placed near the mattress, preferably in a sublimation diffusion device. The invention also relates to a connection device, in particular to a suction device comprising a nozzle, used for the implementation of said method, characterized in that it is produced by a sleeve, arranged perpendicularly on the side strip. peripheral of the mattress, one end of which opens into the internal free space and the other outside of the mattress, and which comprises means of connection to said lateral strip, connection means, in particular to the apparatus for suction, as well as shutter means.
D'autres caractéristiques et avantages ressortiront de la description qui va suivre du procédé et du dispositif associé selon un mode de réalisation préféré, description donnée à titre d'exemple uniquement, en référence aux dessins annexés sur lesquels :Other characteristics and advantages will emerge from the description which follows of the method and of the associated device according to a preferred embodiment, description given by way of example only, with reference to the appended drawings in which:
- Figure 1 est une vue en coupe d'un matelas à ressorts équipé du dispositif selon l'invention,FIG. 1 is a sectional view of a spring mattress equipped with the device according to the invention,
- Figure 2 est une vue de détail en coupe du dispositif selon l'invention, etFIG. 2 is a detailed view in section of the device according to the invention, and
- Figure 3 est une vue en élévation d'une variante du dispositif de l'invention.- Figure 3 is an elevational view of a variant of the device of the invention.
Sur la figure 1 , on a représenté un matelas 1 à ressorts comprenant une face supérieure 2, une face inférieure 4 et une bande latérale périphérique 6, qui définissent une enveloppe du matelas 1 , délimitant un espace interne libre 8. Des ressorts 1 0 sont disposés dans cet espace libre 8 entre les faces supérieure 2 et inférieure 4. De façon connue, sur la bande latérale périphérique 6 du matelas, des moyens d'aération (non représentés), qui facilitent les flux d'air de l'intérieur vers l'extérieur du matelas et inversement, sont prévus.In Figure 1, there is shown a mattress 1 with springs comprising an upper face 2, a lower face 4 and a peripheral lateral strip 6, which define an envelope of the mattress 1, delimiting a free internal space 8. Springs 1 0 are arranged in this free space 8 between the upper 2 and lower 4 faces. In a known manner, on the side strip peripheral 6 of the mattress, ventilation means (not shown), which facilitate air flows from the inside to the outside of the mattress and vice versa, are provided.
Cette bande latérale 6 peut être également équipée d'au moins un dispositif 1 2 de diffusion par sublimation comme décrit dans le brevet français FR-A-92.07870.This side strip 6 can also be equipped with at least one device 1 2 for sublimation diffusion as described in French patent FR-A-92.07870.
Selon l'invention, la bande latérale périphérique 6 est équipée d'au moins un dispositif 1 4 de raccordement, notamment à un appareil d'aspiration tel qu'un aspirateur (non représenté) . Le procédé de traitement sanitaire est maintenant décrit en regard de la figure 1 .According to the invention, the peripheral side strip 6 is equipped with at least one device 1 4 for connection, in particular to a suction device such as a vacuum cleaner (not shown). The sanitary treatment process is now described with reference to FIG. 1.
Un appareil d'aspiration est raccordé à l'aide du dispositif de raccordement 1 4 au matelas 1 . Cet appareil permet de créer une dépression dans l'espace interne libre 8, qui crée un flux d'air de l'extérieur vers l'espace interne libre 8 du matelas, à travers la globalité ou une partie de l'enveloppe du matelas 1 . Ce flux est matérialisé par les flèches 1 6 sur la figure 1 .A suction device is connected using the connection device 1 4 to the mattress 1. This device creates a vacuum in the free internal space 8, which creates an air flow from the outside to the free internal space 8 of the mattress, through the whole or part of the envelope of the mattress 1 . This flow is materialized by the arrows 1 6 in FIG. 1.
Préalablement ou simultanément, un produit contenant des agents actifs 1 8 est diffusé à l'extérieur du matelas dans un environnement proche. Ces agents actifs 1 8 peuvent être des agents actifs pesticides et/ou odorants. On entend par pesticides tous les produits antiparasitaires tel que les fongicides, les insecticides et les bactéricides.Before or simultaneously, a product containing active agents 1 8 is diffused outside the mattress in a close environment. These active agents 18 can be active pesticides and / or odors. Pesticides are understood to mean all pest control products such as fungicides, insecticides and bactericides.
Ces agents actifs 1 8 peuvent être diffusés de différentes façons. La diffusion peut se faire par sublimation de produits solides 20 contenant les agents actifs 1 8, ces produits 20 étant placés à proximité du matelas, de préférence dans un dispositif 1 2 de diffusion par sublimation tel que décrit dans le brevet français FR-A-92.07870.These active agents 1 8 can be diffused in different ways. Diffusion can be done by sublimation of solid products 20 containing the active agents 1 8, these products 20 being placed near the mattress, preferably in a device 1 2 for diffusion by sublimation as described in French patent FR-A- 92.07870.
Elle peut se faire également par pulvérisation des agents actifs 1 8 sous forme de fines particules à l'aide d'une bombe aérosol ou d'un pulvérisateur (non représentés) . Ainsi, avant de pénétrer dans l'espace interne libre 8 du matelas, à travers la globalité ou une partie de l'enveloppe du matelas 1 , l'air se charge en agents actifs 1 8 puis les transporte à l'intérieur du matelas. On constate qu'en diffusant les agents actifs 1 8 par pulvérisation, on obtient un traitement plus efficace, les agents actifs se propageant mieux dans tout l'espace interne libre 8.It can also be done by spraying the active agents 1 8 in the form of fine particles using an aerosol can or a sprayer (not shown). Thus, before entering the free internal space 8 of the mattress, through the whole or part of the envelope of the mattress 1, the air is loaded with active agents 18 then transports them inside the mattress. It can be seen that by diffusing the active agents 18 by spraying, a more effective treatment is obtained, the active agents being better propagated throughout the free internal space 8.
Une fois dans cet espace, les agents actifs du type pesticide agissent et détruisent les parasites.Once in this space, the pesticide-type active agents act and destroy the parasites.
Ce procédé peut permettre également en utilisant un aspirateur pour créer la dépression, d'aspirer les poussières et de renouveler l'air se trouvant dans l'espace interne libre 8.This process can also make it possible, using a vacuum cleaner to create a vacuum, to suck up the dust and to renew the air located in the free internal space 8.
Ce renouvellement de l'air permet notamment une meilleure aération du matelas et évite tout odeur de renfermé ainsi que le développement des parasites.This air renewal notably allows better ventilation of the mattress and avoids any musty smell as well as the development of parasites.
Dans ce cas l'air effectue un circuit. Tout d'abord, l'air passe de l'extérieur vers l'intérieur du matelas grâce au flux d'air référencé 1 6. Ensuite, il est orienté vers le dispositif de raccordement 1 4 grâce au flux d'aspiration référencé 24. Cet air est ensuite dirigé vers l'aspirateur (non représenté) où il est filtré avant d'être rejeté dans la pièce.In this case the air performs a circuit. First, the air passes from the outside towards the inside of the mattress thanks to the air flow referenced 1 6. Then, it is directed towards the connection device 1 4 thanks to the suction flow referenced 24. This air is then directed to the vacuum cleaner (not shown) where it is filtered before being discharged into the room.
Le procédé de l'invention a été décrit en utilisant une dépression afin de créer le flux d'air de l'extérieur vers l'intérieur du matelas.The method of the invention has been described using a vacuum in order to create the air flow from the outside to the inside of the mattress.
Bien entendu, ce flux d'air peut également être créé en propulsant de l'air dans le matelas via le dispositif de raccordement 1 4, les agents actifs 1 8 étant pulvérisés dans le flux d'air entrant. Dans ce cas, il est avantageux de disposer d'un autre dispositif de raccordement 1 4, situé de préférence à l'opposé du premier, afin de faciliter l'évacuation de l'air se trouvant à l'intérieur du matelas. Ce procédé peut être utilisé pour le traitement sanitaire de matelas, notamment à ressorts, ou ayant une ou plusieurs cavités, le nombre et la disposition des dispositifs de raccordement 1 4 étant déterminés afin d'optimiser l'efficacité du procédé.Of course, this air flow can also be created by propelling air into the mattress via the connection device 1 4, the active agents 1 8 being sprayed into the incoming air flow. In this case, it is advantageous to have another connection device 14, preferably located opposite the first, in order to facilitate the evacuation of the air located inside the mattress. This method can be used for the sanitary treatment of mattresses, in particular with springs, or having one or more cavities, the number and arrangement of the connection devices 1 4 being determined in order to optimize the efficiency of the process.
Ce dispositif 1 4 de raccordement selon l'invention, illustré par la figure 2, est maintenant décrit.This connection device 1 4 according to the invention, illustrated in Figure 2, is now described.
Il comprend un manchon 26, disposé perpendiculairement sur la bande latérale 6, et fixé par des moyens 28 de liaison à ladite bande latérale 6. Ce manchon 26, dont une première extrémité 30 débouche dans l'espace interne libre 8 du matelas et l'autre extrémité 32 à l'extérieur du matelas, comprend des moyens 34 de raccord à un appareil d'aspiration et des moyens 36 d'obturation dudit manchon 1 6. Selon un mode de réalisation illustré par la figure 2, les moyens 28 de liaison à la bande latérale 6 sont réalisés par une collerette 38, située à l'extrémité 22 du manchon, qui se plaque contre la face externe de la bande latérale 6, et une contre-plaque 40 qui vient s'emmancher sur le diamètre extérieur du manchon 26 et qui plaque la toile de la bande latérale 6 contre la collerette 38.It comprises a sleeve 26, placed perpendicularly on the side strip 6, and fixed by means 28 for connection to said side strip 6. This sleeve 26, a first end 30 of which opens into the free internal space 8 of the mattress and the other end 32 outside of the mattress, comprises means 34 for connection to a suction device and means 36 for sealing said sleeve 1 6. According to an embodiment illustrated in FIG. 2, the means 28 for connecting to the lateral strip 6 are produced by a collar 38, located at the end 22 of the sleeve, which is pressed against the external face of the lateral strip 6, and a counter plate 40 which is fitted onto the outside diameter of the sleeve 26 and which presses the fabric of the lateral strip 6 against the flange 38.
Les moyens 34 de raccord à un appareil d'aspiration, notamment un aspirateur, sont réalisés grâce à un alésage 42 légèrement conique de l'intérieur du manchon. Avec ce dispositif le raccordement d'un aspirateur est simple, il suffit d'emmancher l'embout 44 d'un tuyau d'aspirateur dans l'alésage 42.The means 34 for connection to a suction device, in particular a vacuum cleaner, are produced by means of a slightly conical bore 42 of the interior of the sleeve. With this device, the connection of a vacuum cleaner is simple, it suffices to fit the end piece 44 of a vacuum cleaner hose into the bore 42.
Afin de pouvoir raccorder des embouts de différents diamètres, l'alésage intérieur du manchon peut être réalisé par une succession d'alésages légèrement coniques, adaptés aux différents diamètres des embouts, les alésages étant disposés suivant les diamètres croissants de l'intérieur vers l'extérieur du matelas.In order to be able to connect ferrules of different diameters, the inner bore of the sleeve can be produced by a succession of slightly conical bores, adapted to the different diameters of the ferrules, the bores being arranged according to the increasing diameters from the interior towards outside of the mattress.
Enfin, pour améliorer l'étanchéité du raccord, des joints peuvent être disposés entre l'alésage 42 et la surface extérieure de l'embout 44.Finally, to improve the tightness of the fitting, seals can be placed between the bore 42 and the outer surface of the end piece 44.
Selon un mode préférentiel de réalisation, les moyens 36 d'obturation du manchon sont réalisés par un bouchon 46 qui vient se visser par exemple à l'extrémité 32 du manchon.According to a preferred embodiment, the means 36 for closing the sleeve are produced by a plug 46 which is screwed, for example at the end 32 of the sleeve.
