Abstract

The invention relates to a sofa equipped with its known mechanism 8 for extension into a bed and for folding up in the compartment of the divan, but in which the mattress, to which the bedding is generally added, consists of an inflatable mattress 1 of parallelepipedal form and of a height at least equal to eight centimetres in the inflated state, the upper and lower faces of which are equipped with cavities 2 uniformly distributed over the surface and which is connected to a mini compressor 5 which is made in a single piece, arranged in a compartment of the divan.

Description

L'invention a trait au domaine de l'ameublement et concerne plus particulièrement les canapés ou divans convertibles en lit, communément dénommés canapés-lits. The invention relates to the field of furniture and more particularly relates to sofas or couches convertible into beds, commonly known as sofa beds.

On sait que le canapé-lit est muni sur son bâti de repose au sol d'un mécanisme à articulations permettant a un plateau-support de se replier en deux ou, plus fréquemment, trois fois sur lui-même de façon à passer aisément de la position lit à celle du canapé ou vice-versa. Le plateau est muni d'un sommier, par exemple à mailles métalliques ou à lattes de bois, et il supporte, par l'intermédiaire généralement d'une toile de protection, un matelas apte à être replié pour rester enfermé dans la cage du plateau articulé lorsque le canapé est utilisé sous forme de simple divan. We know that the sofa bed is provided on its ground rest frame with a hinge mechanism allowing a support plate to fold in half or, more frequently, three times on itself so as to pass easily from the bed position to that of the sofa or vice versa. The tray is provided with a box spring, for example with metal mesh or wooden slats, and it supports, generally by means of a protective fabric, a mattress capable of being folded up to remain enclosed in the cage of the tray articulated when the sofa is used as a simple sofa.

Du fait de la présence de ce mécanisme en acier qui doit avoir un encombrement minimum sous l'assise des coussins du canapé, il n'est pas possible d'utiliser un matelas souple d'une épaisseur supérieure à 5 ou 6 cms, comptetenu par ailleurs de la nécessité de loger également les moyens accessoires de couchage tels que draps et éventuellement couverture. Due to the presence of this steel mechanism which must have a minimum size under the seat of the sofa cushions, it is not possible to use a flexible mattress with a thickness greater than 5 or 6 cms, counted by elsewhere the need to also house the accessory sleeping means such as sheets and possibly blanket.

C'est ainsi que, depuis les nombreuses décades où le canapé-lit a fait son apparition sur le marché, on est obligé de se contenter du couchage tout à fait inconfortable constitué par le mince matelas souple reposant sur un support rigide ou flexible. D'où l'usage le plus souvent à titre d'appoint d'un tel mobilier-lit. Thus, since the many decades when the sofa bed has appeared on the market, we are forced to be content with the completely uncomfortable sleeping consisting of the thin flexible mattress resting on a rigid or flexible support. Hence the use most often as an adjunct to such bed furniture.

L'invention a pour but de résoudre le problème de l'amélioration sensible du confort dans les canapés de ce type, notamment lors de la position dépliée en lit. A cet effet, elle vise la réalisation d'un moyen de couchage qui, tout en conservant les normes indispensables de repli facile et de faible encombrement, autorise un réglage de hauteur selon le poids du ou des usagers et le confort désiré par ces derniers. The object of the invention is to solve the problem of appreciable improvement in comfort in sofas of this type, in particular when the position unfolded in bed. To this end, it aims to achieve a sleeping means which, while retaining the essential standards of easy folding and compact, allows height adjustment according to the weight of the user or users and the comfort desired by them.

Conformément à l'invention, le matelas traditionnel de faible épaisseur, généralement en mousse de matière plastique ou éventuellement du type à ressorts, est remplacé par un matelas gonflable constitué par des faces supérieure et inférieure, reliées par des parois latérales souples d'épaisseur au moins égale à huit centimètres et munies chacune d'alvéoles sensiblement carrées et uniformément réparties sur la surface. In accordance with the invention, the traditional thin mattress, generally made of plastic foam or possibly of the spring type, is replaced by an inflatable mattress constituted by upper and lower faces, connected by flexible lateral walls of thickness less than eight centimeters and each provided with substantially square cells and uniformly distributed over the surface.

I1 a en effet été trouvé que la sélection d'un tel type de matelas, souvent appelé "pavé" et prévu aux dimensions du plateau de couchage, offrait à la fois les avantages d'une grande souplesse pour l'utilisateur et d'une bonne stabilité sur le cadre porteur tant en position de lit que pendant et après la phase de repli. It has in fact been found that the selection of such a type of mattress, often called "paving stone" and provided for the dimensions of the sleeping tray, offers both the advantages of great flexibility for the user and of a good stability on the supporting frame both in bed position and during and after the folding phase.

Selon une réalisation particulièrement avantageuse, le matelas précité est enveloppé, à l'usage, d'une housse capitonnée avec fermeture à glissière. En outre, conformément à un autre mode pratique de mise en oeuvre, le matelas est équipé de façon autonome d'un compresseur monobloc à palettes de faible taille qui peut être avantageusement logé au sein de l'un des montants-accoudoirs du canapé-lit. According to a particularly advantageous embodiment, the aforementioned mattress is wrapped, in use, with a padded cover with zipper. In addition, in accordance with another practical mode of implementation, the mattress is independently equipped with a one-piece compressor with small pallets which can advantageously be accommodated within one of the armrest uprights of the sofa bed .

Comme on peut le voir sur les figures 1 et 3, le matelas gonflable 1 selon l'invention revêt la structure parallélépipédique d'un matelas traditionnel, avec une épaisseur d'au moins huit centimètres (par exemple dix à douze) à l'état gonflé, et ses deux faces réversibles sont constituées par des alvéoles 2 de forme identique uni forme ment réparties sur toute la surface. Le matelas est muni d'au moins une valve pressurisée 3 reliée par ajutage souple 4 à un mini-motocompresseur 5 qui peut être facilement couché dans l'un des socles du divan-lit. Un tel matelas peut être disposé directement sur la toile isolante 6 du plateau sommier 7 qui fait partie du mécanisme -désigné généralement par 8- d'extension et de repli prévu pour le canapé-lit. En pratique, le matelas est protégé par une enveloppe matelassée amovible qui contribue à l'amélioration de l'esthétique et du confort. As can be seen in Figures 1 and 3, the inflatable mattress 1 according to the invention has the parallelepiped structure of a traditional mattress, with a thickness of at least eight centimeters (for example ten to twelve) in the state inflated, and its two reversible faces are formed by cells 2 of identical shape or form distributed over the entire surface. The mattress is provided with at least one pressurized valve 3 connected by flexible nozzle 4 to a mini-compressor 5 which can be easily laid down in one of the bases of the sofa bed. Such a mattress can be placed directly on the insulating fabric 6 of the box spring 7 which is part of the mechanism - generally designated by 8 - of extension and retraction provided for the sofa bed. In practice, the mattress is protected by a removable padded envelope which contributes to the improvement of aesthetics and comfort.

Après usage en position lit, le matelas est dégonflé par ouverture de la valve et il occupe alors un encombrement 1' extrêmement faible qui permet de loger tous les accessoires habituels de couchage. Ceci est illustré sur la figure 2 qui montre un mécanisme de rangement à trois plis (flèches 9, 10, 11) du plateau 7 avec sa position d'attente 7' au pied du dosseret 12 du canapé-lit. After use in the bed position, the mattress is deflated by opening the valve and it then occupies an extremely small footprint 1 'which makes it possible to accommodate all the usual sleeping accessories. This is illustrated in Figure 2 which shows a three-fold storage mechanism (arrows 9, 10, 11) of the tray 7 with its standby position 7 'at the foot of the backsplash 12 of the sofa bed.

On notera, outre les avantages précités, la grande commodité d'usage du système de couchage à coussin d'air selon l'invention du fait que, à tout moment et aussi bien dans les positions d'assise sur divan que de lit, l'usager peut quasi-instantanément modifier par gonflage au dégonflage l'épaisseur du matelas.  It will be noted, in addition to the aforementioned advantages, the great convenience of using the air cushion sleeping system according to the invention because, at all times and as well in the sitting positions on the couch as in the bed, the The user can almost instantly modify the thickness of the mattress by inflation and deflation.
