Description

L'invention trouvera son application dans le domaine des accessoires pour la natation et plus particulièrement dans les matelas flottants pour le divertissement dans l'eau.The invention will find application in the field of accessories for swimming and more particularly in floating mattresses for entertainment in the water.

On connaît des dispositifs flottants pneumatiques qui présentent de nombreux inconvénients tels que la nécessité de les gonfler avant usage ou bien le risque qu'ils crèvent.Pneumatic floating devices are known which have many drawbacks such as the need to inflate them before use or the risk that they burst.

Le document US 4,650,432 décrit un dispositif convertible entre une configuration de radeau et une configuration de matelas et tente. Dans la configuration radeau, un matelas gonflable de forme sensiblement parallélépipédique est recouvert d'une couverture. Sur la couverture sont cousues des poches tubulaires destinées à recevoir des tiges pour former un cadre du radeau. La couverture est fixée de manière amovible de sorte à être dépliée pour être utilisée sous forme de toile de tente.The document US 4,650,432 describes a convertible device between a raft configuration and a mattress and tent configuration. In the raft configuration, an inflatable mattress of substantially parallelepiped shape is covered with a blanket. On the cover are stitched tubular pockets for receiving rods to form a frame of the raft. The cover is removably attached so as to be unfolded for use as a tent.

D'autres types de dispositifs flottants non pneumatiques existent. Leur flottabilité est permise par des matériaux à densité plus faible que l'eau. Ils sont généralement recouverts par un revêtement améliorant notamment le confort et/ou l'esthétique du matelas.Other types of non-pneumatic floating devices exist. Their buoyancy is enabled by materials with a lower density than water. They are generally covered by a coating improving in particular the comfort and / or the aesthetics of the mattress.

Toutefois, ces dispositifs présentent aussi des inconvénients. Ils nécessitent un temps de séchage très long, ce qui s'avère gênant en pratique pour transporter ou ranger le matelas.However, these devices also have disadvantages. They require a very long drying time, which turns out inconvenient in practice for transporting or storing the mattress.

Il existe donc le besoin de proposer un matelas flottant non pneumatique ayant un séchage amélioré.There is therefore the need to provide a non-pneumatic floating mattress having improved drying.

A cet effet, la présente invention concerne un matelas flottant comprenant au moins un matériau flottant recouvert au moins d'un côté par un revêtement et dont au moins une zone du revêtement comporte des orifices pour permettre l'évacuation de l'eau située entre le matériau flottant et le revêtement. Ainsi, la présente invention facilite l'évacuation de l'eau qui a pénétré à l'intérieur du matelas, ce qui permet de réduire le temps de séchage du matelas.For this purpose, the present invention relates to a floating mat comprising at least one floating material covered at least on one side by a coating and at least one area of the coating has orifices to allow the evacuation of water located between the floating material and coating. Thus, the present invention facilitates the evacuation of water that has penetrated the interior of the mattress, thereby reducing the drying time of the mattress.

Préférentiellement, le revêtement est hydrofuge de sorte à ne pas absorber l'eau.Preferably, the coating is water repellent so as not to absorb water.

Pour permettre une évacuation de l'eau satisfaisante, il est préféré que la zone d'évacuation représente de 5 à 35% de la surface du matelas.To allow a satisfactory water evacuation, it is preferred that the evacuation zone represents from 5 to 35% of the surface of the mattress.

Selon une variante de l'invention, le matelas flottant comprend une portion de tête formée par au moins un pan central et deux pans latéraux, un à droite et un à gauche. Les pans latéraux sont configurés pour être repliés sur ou sous le pan central. Cette portion de tête permet ainsi un soutien amélioré de la tête de l'utilisateur.According to a variant of the invention, the floating mat comprises a head portion formed by at least one central panel and two side panels, one on the right and one on the left. The side panels are configured to be folded over or under the central panel. This head portion thus provides improved support for the user's head.

Le matelas flottant selon l'invention est destiné à être utilisé en piscine, en mer ou bien encore sur des lacs ou rivières. Le matelas flottant permet de soutenir et de faire flotter un enfant ou bien un adulte.The floating mattress according to the invention is intended to be used in the pool, at sea or on lakes or rivers. The floating mattress can support and float a child or an adult.

Selon l'invention, le matelas flottant comprend au moins un matériau flottant 11. Préférentiellement, le matériau flottant 11 comprend au moins une couche de matériau ayant une densité inférieure à la densité de l'eau. Le matériau flottant 11 est recouvert sur au moins une de ses faces d'un revêtement. Avantageusement, le revêtement est disposé sur une face destinée à être en contact avec l'utilisateur. A titre préféré, le revêtement est formé d'une couche de matériau destinée à améliorer le confort de l'utilisateur lors du contact avec le matelas et/ou améliorer l'esthétisme du matelas notamment en permettant une sérigraphie.According to the invention, the floating mat comprises at least one floating material 11. Preferably, the floating material 11 comprises at least one layer of material having a density less than the density of the water. The floating material 11 is covered on at least one of its faces with a coating. Advantageously, the coating is disposed on a face intended to be in contact with the user. As a preference, the coating is formed of a layer of material intended to improve the user's comfort during contact with the mattress and / or to improve the aesthetics of the mattress, in particular by allowing screen printing.

Le revêtement n'est pas destiné à contribuer à la flottabilité du matelas. Le revêtement peut être en tissu ou plastique ou autre matériau. Il est préférable de choisir un matériau ne retenant pas l'eau de sorte à limiter l'intrusion d'eau entre le revêtement et matériau flottant 11 et ainsi améliorer encore le séchage du matelas. Ce matériau peut être hydrofuge ou imperméable.The coating is not intended to contribute to the buoyancy of the mattress. The coating may be of fabric or plastic or other material. It is preferable to choose a material that does not retain water so as to limit the intrusion of water between the coating and floating material 11 and thus further improve the drying of the mattress. This material can be water repellent or waterproof.

A titre d'exemple, le revêtement est choisi parmi les matériaux tels que le polyester ou bien le polyamide. On entend par matériau hydrofuge, un matériau qui n'absorbe pas l'eau aussi dénommé matériau déperlant.By way of example, the coating is chosen from materials such as polyester or polyamide. By water-repellent material is meant a material that does not absorb water, also referred to as water-repellent material.

Selon l'invention, le revêtement forme préférentiellement une première couche 9 sur la première face du matériau flottant 11 et une deuxième couche 10 sur l'autre face du matériau flottant. Le matelas comprend un matériau flottant 11 intercalé entre une première couche 9 et une deuxième couche 10 de revêtement. Le revêtement enveloppe l'ensemble du matériau flottant 11. Le revêtement enveloppe toutes les faces du matériau flottant 11.According to the invention, the coating preferentially forms a first layer 9 on the first face of the floating material 11 and a second layer 10 on the other side of the floating material. The mattress comprises a floating material 11 interposed between a first layer 9 and a second layer 10 of coating. The coating envelops the whole of the floating material 11. The coating envelops all the faces of the floating material 11.

C'est grâce au matériau flottant que le matelas possède ses propriétés de flottaison.It is thanks to the floating material that the mattress has its flotation properties.

A titre d'exemple, le matelas selon l'invention a une épaisseur comprise entre un centimètre et six centimètres préférentiellement de l'ordre de deux centimètres.By way of example, the mattress according to the invention has a thickness of between one centimeter and six centimeters, preferably of the order of two centimeters.

De manière caractéristique, le matelas selon l'invention comprend une zone d'évacuation d'eau 2 dans laquelle le revêtement comporte des orifices agencés pour faciliter l'évacuation de l'eau située entre le matériau flottant et le revêtement.Typically, the mattress according to the invention comprises a water discharge zone 2 in which the coating has orifices arranged to facilitate the evacuation of water between the floating material and the coating.

Le matériau flottant 11 est selon un mode de réalisation préféré du polyéthylène expansé à basse densité. Préférentiellement, un polyéthylène expansé avec une densité de l'ordre de 32Kg/m3 peut être utilisé. Le matériau flottant 11 est à densité plus faible que l'eau. Un tel matériau peut être trouvé dans le commerce sous la marque Fibre Air®. Il est préférable d'utiliser le matériau flottant 11 en une pluralité de couches, permettant ainsi de supporter un poids très important.The floating material 11 is according to a preferred embodiment of the low density expanded polyethylene. Preferably, an expanded polyethylene with a density of the order of 32 Kg / m 3 can be used. The floating material 11 is at a lower density than water. Such a material can be found commercially under the Fiber Air® brand. It is preferable to use the floating material 11 in a plurality of layers, thus allowing to bear a very large weight.

Selon une possibilité préférée, le matériau à densité plus faible que l'eau intègre un gaz plus léger que l'air contribuant à améliorer les propriétés de flottaison dudit matériau.According to one preferred possibility, the material with a lower density than water incorporates a lighter gas than air, which contributes to improving the flotation properties of said material.

A titre d'information, ce matériau connu sous la marque Fibre Air® pèse 16 grammes et a une épaisseur de 0,5 millimètres pour un mètre carré de fibre.For information, this material known as Fiber Air® weighs 16 grams and has a thickness of 0.5 millimeters per square meter of fiber.

Préférentiellement, la pluralité de couches de ce matériau est composée de dix à quinze couches, plus précisément quinze couches.Preferably, the plurality of layers of this material is composed of ten to fifteen layers, more precisely fifteen layers.

Selon une variante avantageuse, le matelas flottant selon l'invention comporte trois couches de ce matériau.According to an advantageous variant, the floating mattress according to the invention comprises three layers of this material.

Selon un mode de réalisation préféré, les couches de matériau flottant 11 sont fractionnées en sous-sections de plusieurs couches, à titre d'exemple cinq. Ces sections de couches de matériau flottant sont séparées les unes des autres par un matériau du type non tissé. Le matériau a pour but de faciliter l'écoulement de l'eau pour la conduire plus rapidement en direction de la zone d'évacuation d'eau 2. Le matériau de type non tissé est par exemple en polyester et présente une épaisseur de 0,6 millimètres.According to a preferred embodiment, the layers of floating material 11 are subdivided into subsections of several layers, for example five. These sections of layers of floating material are separated from each other by a material of the nonwoven type. The purpose of the material is to facilitate the flow of water in order to drive it more rapidly towards the water discharge zone 2. The nonwoven material is, for example, made of polyester and has a thickness of 0, 6 millimeters.

Il est avantageux de prévoir également au moins une couche de ce matériau non tissé directement sous le revêtement, c'est-à-dire entre le revêtement et le matériau flottant 11.It is advantageous to also provide at least one layer of this nonwoven material directly under the coating, that is to say between the coating and the floating material 11.

La configuration en épaisseur d'un matelas selon l'invention est à titre d'exemple du type : revêtement - matériau non tissé - matériau flottant, par exemple cinq couches de Fibre Air ® - matériau non tissé - matériau flottant, par exemple cinq couches de Fibre Air ® - matériau non tissé - matériau flottant, par exemple cinq couches de Fibre Air ® - matériau non tissé - revêtement.The thickness configuration of a mattress according to the invention is for example of the type: coating - nonwoven material - floating material, for example five layers of Fiber Air ® - nonwoven material - floating material, for example five layers Fiber Air ® - nonwoven material - floating material, for example five layers of Fiber Air ® - nonwoven material - coating.

La propriété physique de ce matériau ayant une densité plus faible que l'eau connue sous la marque Fibre Air® fait ressortir que 250 grammes de ce matériau font flotter une masse corporelle de 130 kg.The physical property of this material having a lower density than the water known as Fiber Air® shows that 250 grams of this material float a body mass of 130 kg.

Cette pluralité de couches ayant une densité plus faible que l'eau possède des propriétés de flottaison intéressantes sans présenter aucun risque de crevaison. En effet, le matelas flottant selon l'invention n'est pas pneumatique.This plurality of layers having a lower density than water has interesting flotation properties without any risk of punctures. Indeed, the floating mattress according to the invention is not pneumatic.

De ce fait, le matelas selon l'invention, s'utilise également sur un sol tel que du sable, galets, herbe, carrelage pour améliorer le confort de l'utilisateur souhaitant s'allonger.Therefore, the mattress according to the invention is also used on a floor such as sand, pebbles, grass, tiles to improve the comfort of the user wishing to lie down.

Il est avantageux de prévoir que le matelas soit flexible, le matériau flottant 11 et le revêtement sont donc flexibles pour permettre de plier le matelas.It is advantageous to provide that the mattress is flexible, the floating material 11 and the coating are therefore flexible to allow folding the mattress.

Les orifices de la zone d'évacuation 2 sont configurés pour laisser passer l'eau. Préférentiellement, le revêtement comportant les orifices est hydrofuge de sorte à laisser passer l'eau au travers sans l'absorber.The orifices of the evacuation zone 2 are configured to let the water pass. Preferably, the coating comprising the orifices is water-repellent so as to allow the water to pass therethrough without absorbing it.

Les orifices sont formés par différentes possibilités : premièrement, des trous sont réalisés dans le revêtement au niveau de la zone d'évacuation d'eau 2 ou deuxièmement, le revêtement comportant les orifices dans la zone d'évacuation d'eau 2 est différent du revêtement recouvrant le reste du matériau flottant. Le matériau flottant 11 comportant des orifices est ainsi un filet ou un matériau à mailles.The orifices are formed by different possibilities: first, holes are made in the coating at the water discharge zone 2 or secondly, the coating having the orifices in the water discharge zone 2 is different from the coating covering the rest of the floating material. The floating material 11 having orifices is thus a net or a mesh material.

Les orifices sont des ouvertures traversant l'épaisseur du revêtement.The orifices are openings through the thickness of the coating.

La taille des orifices est adaptée pour permettre un écoulement de l'eau satisfaisant. A titre d'exemple, les orifices sont de taille allant de 0,2 millimètres à 10 millimètres.The size of the orifices is adapted to allow a satisfactory flow of water. For example, the orifices are of size ranging from 0.2 millimeters to 10 millimeters.

La zone d'évacuation 2 est disposée sur une face du matériau flottant 11. La zone d'évacuation 2 est préférentiellement une surface plane s'étendant sur au moins une partie d'une face du matériau flottant 11.The evacuation zone 2 is disposed on one face of the floating material 11. The evacuation zone 2 is preferably a flat surface extending over at least a part of a face of the floating material 11.

Tel que représenté sur l'ensemble des figures, le matelas flottant selon l'invention est de forme rectangulaire. D'autres formes pourraient être envisagées telles que rondes ou bien carrées ou encore des formes complexes. Le matelas peut être pour une personne ou bien pour deux personnes.As shown in all the figures, the floating mattress according to the invention is of rectangular shape. Other forms could be envisaged such as round or square or complex shapes. The mattress can be for one person or for two people.

De sorte à maintenir assemblés le matériau flottant 11 et le revêtement, des coutures sont préférentiellement réalisées sur le pourtour du matelas et/ou sur la surface même dudit matelas tel que représenté sur l'ensemble des figures. Ces coutures forment des zones de coutures 8 préférentiellement orientées selon l'axe longitudinal du matelas flottant.So as to maintain assembled the floating material 11 and the coating, seams are preferably made on the periphery of the mattress and / or on the very surface of said mattress as shown in all the figures. These seams form seam areas 8 preferably oriented along the longitudinal axis of the floating mattress.

Dans le cadre du développement de l'invention, il s'est avéré que c'est notamment par les zones de coutures 8 que l'eau pénètre, au travers du matelas, entre le revêtement et le matériau flottant. En effet, lors de la piqûre du revêtement, l'étanchéité éventuelle du matériau est entamée, même légèrement, permettant alors la pénétration de l'eau.In the context of the development of the invention, it has been found that it is in particular through the seam zones 8 that the water penetrates, through the mattress, between the coating and the floating material. Indeed, during the pitting of the coating, the possible sealing of the material is started, even slightly, allowing the penetration of water.

Les lignes de couture 8 s'étendent longitudinalement et en direction de la zone d'évacuation 2. Elles sont ainsi agencées de sorte à favoriser le drainage de l'eau comprise entre le matériau flottant 11 et le revêtement vers la zone d'évacuation 2.The seam lines 8 extend longitudinally and in the direction of the discharge zone 2. They are thus arranged so as to promote the drainage of the water between the floating material 11 and the coating towards the evacuation zone 2 .

La configuration du matelas selon l'invention va à l'encontre des préjugés du métier qui pour éviter toute pénétration d'eau à l'intérieur dudit matelas aurait tenté de limiter l'entrée d'eau par les zones sensibles, notamment par un choix spécifique de matériau étanche ou par des zones de coutures 8 améliorées, mais n'aurait pas envisagé de créer une zone d'évacuation d'eau 2 laissant aussi pénétrer plus d'eau à l'intérieur du matelas.The configuration of the mattress according to the invention goes against the prejudices of the trade which to prevent any water penetration inside said mattress would have tried to limit the entry of water by the sensitive areas, in particular by a choice specific waterproof material or improved seam areas 8, but would not have envisaged creating a water evacuation zone 2 also allowing more water to enter the interior of the mattress.

Selon une possibilité avantageuse, la zone d'évacuation d'eau 2 est disposée transversalement sur le matelas. Ainsi, les zones de coutures 8 forment des gouttières drainant l'eau à la surface du matériau hydrofuge formant la première couche 9 et la deuxième couche 10 ainsi que l'eau présente à l'intérieur du matelas en direction de la zone d'évacuation d'eau 2.According to an advantageous possibility, the water discharge zone 2 is arranged transversely on the mattress. Thus, the seam zones 8 form gutters draining the water on the surface of the water-repellent material forming the first layer 9 and the second layer 10 as well as the water present inside the mattress towards the evacuation zone. of water 2.

Le déposant s'est aperçu que pour obtenir un séchage efficace, la zone d'évacuation d'eau 2 devait préférentiellement représenter de 5% à 35%, plus précisément de 10 à 25% de la surface dudit matelas et au moins 10%.The applicant has found that to obtain effective drying, the water discharge zone 2 should preferably represent from 5% to 35%, more precisely from 10 to 25% of the surface of said mattress and at least 10%.

Il est avantageux de prévoir que le pourtour 3 du matelas soit formé d'un biais cousu sur l'ensemble du matelas. Ce biais est préférentiellement formé d'un revêtement comportant des orifices identiques à ceux formant la zone d'évacuation d'eau 2. De la sorte, le biais situé au pourtour 3 du matelas constitue également une zone d'évacuation d'eau 2 présente à l'intérieur du matelas.It is advantageous to provide that the periphery 3 of the mattress is formed of a bias sewn over the entire mattress. This bias is preferably formed of a coating having orifices identical to those forming the water discharge zone 2. In this way, the bias located at the periphery 3 of the mattress also constitutes a water discharge zone 2 present inside the mattress.

Comme représenté sur l'ensemble des figures, les zones de coutures 8 délimitent plusieurs bandes.As shown in all the figures, the seam areas 8 delimit several bands.

A titre préféré, le matelas selon l'invention comprend au moins une portion centrale 6, une portion latérale droite 4 et une portion latérale gauche 5. Ces portions 4, 5, 6 sont préférentiellement délimitées par des zones de coutures 8. De même, il est préféré de prévoir une portion de tête 12. Cette portion de tête 12 est située à une extrémité longitudinale du matelas.By way of preference, the mat according to the invention comprises at least one central portion 6, a right lateral portion 4 and a left lateral portion 5. These portions 4, 5, 6 are preferably delimited by seam zones 8. Likewise, it is preferred to provide a head portion 12. This head portion 12 is located at a longitudinal end of the mattress.

Selon un mode de réalisation préféré, la zone d'évacuation d'eau 2 est disposée à l'extrémité longitudinale opposée à la portion de tête 12.According to a preferred embodiment, the water discharge zone 2 is disposed at the longitudinal end opposite to the head portion 12.

De sorte à améliorer le maintien de la tête de l'usager, la portion de tête 12 est formée dans le prolongement de la portion centrale 6 du matelas et comprend un pan central 1 directement dans le prolongement de la portion centrale 6. Le pan central 1 est entouré par un pan latéral gauche 14 et un pan latéral droit 13.So as to improve the maintenance of the head of the user, the head portion 12 is formed in the extension of the central portion 6 of the mattress and comprises a central panel 1 directly in the extension of the central portion 6. The central panel 1 is surrounded by a left lateral pan 14 and a right lateral pan 13.

Comme représenté sur les figures, la largeur de la portion de tête 12 est avantageusement équivalente à la largeur du matelas. Le pan latéral gauche 14 et le pan latéral droit 13 sont indépendants de la portion latérale gauche 5 et de la portion latérale droite 4. Il y a une discontinuité 15 entre les portions latérales 4 - 5 et les pans latéraux 12 - 14. Cette configuration est avantageuse puisqu'elle permet le repliement du pan latéral droit 13 et/ou du pan latéral gauche 14 sur et/ou sous le pan central 1 de la portion de tête 12. Ce repliement forme alors un appuie-tête satisfaisant pour l'utilisateur.As shown in the figures, the width of the head portion 12 is advantageously equivalent to the width of the mattress. The left lateral pan 14 and the right lateral pan 13 are independent of the left lateral portion 5 and the right lateral portion 4. There is a discontinuity 15 between the lateral portions 4 - 5 and the lateral panels 12 - 14. This configuration is advantageous since it allows the folding of the right lateral pan 13 and / or the left lateral pan 14 on and / or under the central panel 1 of the head portion 12. This folding then forms a headrest satisfactory for the user .

Le matelas selon l'invention est aisément repliable pour permettre son transport. Ainsi, il comprend selon une variante des moyens de fixation 7.The mattress according to the invention is easily foldable to allow its transport. Thus, according to one variant, it comprises fastening means 7.

Selon le mode de réalisation préféré représenté sur l'ensemble des figures, le matelas selon l'invention comprend des moyens de fixation 7 formés sous forme de pattes munies de matériau auto-agrippant tel que du Velcro® coopérant avec des pattes formées dans un matériau auto-agrippant correspondant sur une autre partie du matelas. Le repliement du matelas se fait ainsi de manière aisée en repliant la portion latérale gauche 5 ou la portion latérale droite 4 non munie des pattes de fixation sur ou sous la portion centrale 6. Ensuite, le repliement de l'autre portion latérale droite 4 ou gauche 5 munie des pattes d'accrochage par-dessus ou par-dessous la portion centrale 6 superposée à la portion latérale gauche 5 ou droite 4 de sorte à permettre la coopération entre les pattes d'accrochage.According to the preferred embodiment shown in all the figures, the mattress according to the invention comprises fixing means 7 formed in the form of tabs provided with self-gripping material such as Velcro® cooperating with tabs formed of a material corresponding self-gripping on another part of the mattress. The folding of the mattress is thus done easily by folding the left lateral portion 5 or the right lateral portion 4 not provided with the fastening tabs on or under the central portion 6. Then, the folding of the other right lateral portion 4 or left 5 provided with hooking tabs above or below the central portion 6 superimposed on the left side portion 5 or right 4 so as to allow cooperation between the attachment tabs.

Le matelas est préférentiellement replié tout d'abord de manière longitudinale puis ensuite de manière transversale en deux.The mattress is preferably folded first longitudinally and then transversely in two.
