Description
La présente invention a pour objet un coussin d'ameublement d'extérieur à séchage rapide.The present invention relates to a quick-drying outdoor upholstery cushion.
La présente invention appartient au domaine des accessoires d'ameublement, tels que les coussins ou matelas, permettant de réaliser une interface entre un utilisateur et l'assise d'un support comme par exemple une chaise, une chaise longue, un lit, une banquette de bateau, etc., dans le but principal d'améliorer le confort.The present invention belongs to the field of furniture accessories, such as cushions or mattresses, for providing an interface between a user and the seat of a support such as a chair, a deck chair, a bed, a bench seat boat, etc., with the main purpose of improving comfort.
Dans la suite de la description, le terme coussin recouvre également les matelas et plus généralement tout moyen d'assise.In the rest of the description, the term cushion also covers the mattresses and more generally any seating means.
Plus particulièrement, l'invention se destine à être utilisée en milieu extérieur. Ainsi, par exemple, le coussin peut être exposé à la pluie, la neige, au vent et au soleil.More particularly, the invention is intended to be used in an external environment. For example, the cushion may be exposed to rain, snow, wind and sun.
Un coussin d'ameublement se compose en général d'une enveloppe en matériau souple délimitant un espace intérieur, ledit espace intérieur étant comblé par un rembourrage déformable permettant d'épouser la forme de l'utilisateur, et ainsi de procurer à celui-ci du maintien et du confort.A furnishing cushion generally consists of an envelope of flexible material delimiting an interior space, said interior space being filled by a deformable padding allowing the shape of the user to be matched, and thus to provide the latter with maintenance and comfort.
Le rembourrage peut être composé par exemple de matériaux naturellement floculents, comme de la laine, du crin, des fibres végétales, ou des matériaux synthétiques, comme des fibres synthétiques ou des mousses.The padding can be composed for example of naturally flocculent materials, such as wool, horsehair, vegetable fibers, or synthetic materials, such as synthetic fibers or foams.
La durée de vie d'un coussin d'ameublement pour l'extérieur est réduite.The service life of an outdoor furniture cushion is reduced.
En effet, les intempéries auxquelles il est exposé font que l'enveloppe et le rembourrage sont régulièrement humides. Cette humidité, combinée aux écarts de température liés aux saisons et à l'ensoleillement, peut engendrer le développement de mousses et de bactéries dans l'enveloppe et dans le rembourrage. Il existe donc un risque pour la peau de l'utilisateur. En outre, l'aspect extérieur et la solidité dudit coussin se trouvent altérés.Indeed, the bad weather to which it is exposed makes that the envelope and the padding are regularly wet. This moisture, combined with seasonal and sunshine-related temperature differences, can cause foams and bacteria to grow in the envelope and in the padding. There is therefore a risk for the skin of the user. In addition, the external appearance and the strength of said cushion are altered.
En outre, après une averse ou un orage, le coussin est gorgé d'eau et devient inutilisable. Le séchage est de plusieurs heures, voire de plusieurs jours, l'eau restant emprisonnée dans la mousse.In addition, after a shower or thunderstorm, the cushion is waterlogged and becomes unusable. The drying is several hours, or even several days, the water remaining trapped in the foam.
La solution la plus commune pour empêcher l'eau de pénétrer dans le coussin, consiste à rendre l'enveloppe imperméable à l'eau et à la vapeur d'eau en l'enduisant d'un matériau imperméable à l'eau, avantageusement un matériau polymérique.The most common solution to prevent water from entering the cushion, is to make the envelope impervious to water and steam by coating it with a waterproof material, preferably a polymeric material.
L'étape d'enduction tend à augmenter le coût du coussin. En outre, l'enduction empêche le tissu de respirer et engendre des phénomènes de transpiration pour l'utilisateur.The coating step tends to increase the cost of the cushion. In addition, the coating prevents the tissue from breathing and causes perspiration phenomena for the user.
Le but de la présente invention est de pallier aux inconvénients précités.The object of the present invention is to overcome the aforementioned drawbacks.
Pour ce faire, le Demandeur a mis au point un coussin d'ameublement d'extérieur composé essentiellement de deux éléments, en l'espèce une enveloppe perméable à l'eau, avantageusement en tissu 3D alvéolé composé de fibres synthétiques, polymériques, ladite enveloppe renfermant un rembourrage en mousse polymériques à cellules ouvertes.To do this, the Applicant has developed an outdoor upholstery cushion consisting essentially of two elements, in this case a water-permeable envelope, advantageously made of 3D honeycomb fabric composed of synthetic, polymeric fibers, said envelope enclosing polymeric open cell foam padding.
La combinaison du 3D, des alvéoles et des fibres synthétiques fait que l'eau passe à travers l'enveloppe par gravité. L'enveloppe n'absorbe pas l'eau. Après aspersion d'eau, le tissu 3D redevient donc totalement sec en quelques instants.The combination of 3D, cells and synthetic fibers makes the water pass through the envelope by gravity. The envelope does not absorb water. After spraying with water, the 3D fabric becomes completely dry again in a few moments.
Selon l'invention, les fibres de l'enveloppe sont choisies dans le groupe comprenant polyester, polypropylène (PP), polyéthylène (PE), polyamide (PA), polyéthylène téréphtalate (PET), éthylène alcool vinylique (EVOH), polychlorure de vinylidène (PVDC).According to the invention, the fibers of the envelope are chosen from the group comprising polyester, polypropylene (PP), polyethylene (PE), polyamide (PA), polyethylene terephthalate (PET), ethylene vinyl alcohol (EVOH), polyvinylidene chloride (PVDC).
Il s'agit avantageusement de fibres exclusivement de polyester.It is advantageously exclusively polyester fibers.
Selon une caractéristique essentielle de l'invention, le tissu 3D de l'enveloppe a un grammage compris entre 100 et 500 g/m2, préférentiellement 230 g/m2.According to an essential characteristic of the invention, the 3D fabric of the envelope has a basis weight of between 100 and 500 g / m 2 , preferably 230 g / m 2 .
Dans un autre mode de réalisation, l'enveloppe est faite d'un tissu respirant composé de plusieurs couches assemblées.In another embodiment, the envelope is made of a breathable fabric composed of several assembled layers.
La mousse polymérique à cellules ouvertes constitutive du rembourrage présente des caractéristiques de perméabilité similaires à celle de l'enveloppe. Elle offre ainsi une perméabilité totale à l'eau et à la vapeur d'eau, et n'absorbe pas l'eau. Elle redevient donc totalement sèche en quelques instants après aspersion d'eau.The open-cell polymeric foam constituting the padding has permeability characteristics similar to that of the shell. It thus offers complete permeability to water and water vapor, and does not absorb water. It becomes completely dry again in a few moments after water spraying.
Avantageusement, on utilise une mousse polymérique à cellules ouvertes en polyuréthane, ayant une densité de préférence comprise entre 15 et 40 kg/m3, avantageusement égale à 20 kg/m3.Advantageously, a polyurethane open-cell polymeric foam having a density of preferably between 15 and 40 kg / m 3 , advantageously equal to 20 kg / m 3, is used .
En pratique, le rembourrage a une épaisseur comprise entre 1 et 50 cm, avantageusement entre 5 et 45 cm.In practice, the padding has a thickness of between 1 and 50 cm, advantageously between 5 and 45 cm.
Grâce à la combinaison avantageuse de ces matériaux composant l'enveloppe et le rembourrage, le coussin est poreux. L'eau circule ainsi à travers le coussin sans stagner ni dans l'épaisseur de l'enveloppe, ni dans le rembourrage. Il n'y a pas de possibilité de formation de vapeur d'eau dans l'enveloppe. Le risque d'un développement bactérien ou de champignons dans le coussin est donc écarté, augmentant significativement la durée de vie de l'invention par rapport aux coussins de l'art antérieur.Thanks to the advantageous combination of these materials composing the envelope and the padding, the cushion is porous. The water circulates through the cushion without stagnating either in the thickness of the envelope or in the padding. There is no possibility of formation of water vapor in the envelope. The risk of bacterial growth or fungi in the cushion is therefore eliminated, significantly increasing the life of the invention compared to the cushions of the prior art.
Selon une autre caractéristique, l'enveloppe présente des moyens de fermeture réversibles permettant d'avoir un accès au rembourrage.According to another characteristic, the envelope has reversible closure means allowing access to the padding.
Dans un mode de réalisation préféré, les moyens de fermeture se présentent sous la forme d'une fermeture à glissière.In a preferred embodiment, the closure means is in the form of a zipper.
Dans un autre mode de réalisation, l'enveloppe est thermo scellée de sorte qu'il n'est plus possible d'accéder au rembourrage.In another embodiment, the envelope is thermally sealed so that it is no longer possible to access the padding.
