Abstract

The method involves disposing a mesh-spring bed frame (110) of a bed (100) in a sleeping arrangement position, in a horizontal plane raised with respect to ground, to release a housing. The housing receives furnishing and/or work installing units (300) before providing the bed into a room. The bed is retracted by vertical movement of the frame towards a storage position situated in plane parallel to that of the sleeping position. An independent claim is also included for a device for implementing a bed retracting method.

Description

PROCEDE D'ESCAMOTAGE D'UN LIT ET DISPOSITTF PERMETTANT DE METTRE EN OEUVRE UN TEL DISPOSITIF. METHOD OF ESCAMOTATING A BED AND DEVICE FOR IMPLEMENTING SUCH A DEVICE.
DOMAINE D'APPLICATION DE L'INVENTION La présente invention a trait au domaine de l'ameublement et/ou de l'aménagement intérieur et concerne plus précisément un procédé et un dispositif permettant d'escamoter un lit à des fins de rangement et de stockage. DESCRIPTION DE L'ART ANTERIEUR Un lit se compose classiquement d'un piètement qui, formé le plus souvent de quatre pieds, assure l'assise surélevée d'un châssis horizontal sur lequel on peut déposer un matelas que recouvrent d'autres articles de literie comme le drap, la couverture, ou la couette permettant notamment d'isoler l'homme du matelas. De nombreux efforts ont été développés ces dernières années dans le souci de donner aux lits un caractère esthétique, respectant bien souvent l'évolution de la société tout en étant tributaire de l'esprit de leurs novateurs. Les efforts ont également portés sur différents modes d'exécution de lits visant généralement à modifier leur structure et/ou leur destination afin d'assumer diverses positions et/ou fonctions ou encore d'améliorer le confort des personnes assises. Cependant, dans des pièces appelées à rassembler dans un minimum d'espace un certain nombre d'éléments tant ceux nécessaires à l'ameublement pour le rangement, le travail et le couchage intégrant nécessairement un lit que ceux relatifs aux installations et appareils destinés aux soins de propreté et à la préparation et/ou à la prise de repas, il a été souvent constaté que les lits équipant ce type de pièces sont disposés à demeure, interdisant ipso facto l'utilisation de l'emplacement au sol de la pièce occupé par le lit à d'autres fins. Aussi, lorsqu'il devient nécessaire de libérer l'espace de l'emplacement de la pièce pris par le lit, il n'existe à ce jour que deux alternatives. La première alternative est celle des "vases communicants" qui consiste "à vider" la pièce en question tout en "remplissant" une pièce voisine et vice-versa. Cette alternative impose donc des structures légères qui s'adressent plus particulièrement aux lits démontables dits souvent d'appoint comme le lit de camp se composant essentiellement d'un châssis pliable garni de sangles ou d'une grosse toile faisant office de sommier et de matelas. La deuxième alternative est le lit escamotable qui consiste à faire pivoter ledit lit sur un de ses côtés de préférence sur son côté latéral de la tête de lit afin de pouvoir le dresser parallèlement à l'un des murs auquel il sera retenu dans cette position une fois dressé en le manœuvrant à partir de l'autre côté latéral du pied de lit de manière à faire exécuter audit lit un mouvement de basculement. Ces deux alternatives présentent l'inconvénient majeur d'être contraignantes du fait qu'elles ne libèrent qu'un espace libre au sol provisoire qui doit être nécessairement aménagé et déménagé rapidement des éléments nécessaires à une autre utilisation entre deux utilisations de couchage successives du lit. Il n'est donc pas envisageable de laisser à demeure d'autres éléments qui doivent aussi être rangés sur un autre emplacement de la pièce ou dans une autre pièce (d'où le terme de vases "communicants") lorsque le lit est en position de couchage. L'assise du lit dans la première alternative est pliée et dans la deuxième basculée d'une position horizontale vers une position verticale et vice versa, ce qui nécessite de refaire complètement le lit après chaque manipulation. De plus, le fait d'utiliser des structures légères et discrètes pour que lesdits lits soient facilement dissimulés en position de rangement ne peut pas contribuer à une bonne qualité de literie. DESCRIPTION DE L'INVENTION Partant de cet état de fait et d'un cahier des charges préétabli, les demandeurs ont mené des recherches qui ont abouti à un concept original de lit qui tout en obviant à l'ensemble des inconvénients précités permet de libérer son emplacement au sol dans une pièce sans être contraint de sortir et/ou de déplacer vers un autre espace le lit l'équipant. Pour ce faire, les demandeurs ont imaginé un procédé original d'escamotage d'un lit du type d'un châssis formant sommier supportant un matelas et porté par un piètement. Ce procédé du type de celui permettant de faire évoluer le lit d'une position horizontale d'utilisation dite de couchage vers une position d'escamotage dite de rangement et vice versa est, selon l'invention, remarquable en ce qu'il consiste à disposer le châssis dudit lit dans la position de couchage dans un plan horizontal surélevé par rapport au sol de manière à libérer en dessous, un logement suffisamment haut pour recevoir d'autres éléments d'ameublement et/ou d'installations de travail devant équiper la pièce en plus dudit lit. Le grand avantage d'un tel procédé d'escamotage est donc de permettre d'avoir un lit qui, en position de couchage, garde intégralement libre son emplacement au sol de sorte qu'il peut y dédier l'installation à demeure d'un autre ameublement ou appareil électroménager. Ainsi, par exemple, il sera judicieux et c'est une des principales préférences d'aménagement intérieur proposée par les demandeurs, de prévoir l'installation d'une table d'un bureau de travail qui bien souvent occupe sensiblement la même surface d'emplacement au sol qu'un lit. Cet aménagement est particulièrement intéressant notamment dans les chambres estudiantines d'université aux dimensions très petites mais où il est maintenant de plus en plus demandé à l'architecte-concepteur de composer pour réunir dans un minimum de surface au sol (environ 9 m2) tous les équipements sanitaires (douche, lavabo, Water- Closet), de préparation et de prise de repas (cuisinette, table et chaises), de rangement (étagères, placards, penderie) et de travail (bureau, ordinateur, téléphone), etc.. Partant du fait qu'une chambre estudiantine occupe une surface au sol d'environ 9 m2 avec une réservation meublée de moins de la moitié et que le lit occupe au moins une surface de l'ordre de 1,80 m2, le procédé d'escamotage de l'invention permet donc d'envisager obtenir un gain de place de presque 40% qui pourra ainsi être comblé par d'autres équipements. Un autre avantage de l'invention outre celui primordial du gain de place précité réside dans le fait que le lit qui est rarement un meuble esthétique dans les pièces du type studio ou chambre estudiantine où de plus l'ordre n'est pas souvent la première qualité de son habitant, peut être dissimulé à la vue grâce au procédé d'escamotage qui garde ici sa fonction première. L'invention propose divers modes de réalisation du procédé d'escamotage d'un lit. Un premier mode de réalisation consiste à escamoter le lit par un mouvement vertical du châssis vers une position de rangement située dans un plan parallèle au plan de la position de couchage selon une hauteur suffisante pour dégager un espace libre de travail au- dessus des éléments d'ameublement et/ou d'installation de travail pour autoriser leur utilisation. Par exemple et comme on le verra un peu plus en détails dans la description appuyée sur les dessins, le châssis du susdit lit pourra évoluer d'une position escamotée de rangement à une position d'utilisation de couchage par un mouvement de coulissement vertical. Un autre mode de réalisation consiste à escamoter ledit lit par un mouvement horizontal du châssis vers une position de rangement située dans le même plan horizontal que celui de la position de couchage selon une hauteur suffisante pour dégager ainsi jusqu'au plafond un espace libre de travail au-dessus des éléments d'ameublement et/ou d'installation de travail pour autoriser leur utilisation. Par exemple, le châssis du susdit lit pourra évoluer d'une position escamotée de rangement à une position d'utilisation de couchage soit par un mouvement de pivotement horizontal soit par un mouvement de coulissement horizontal. BREVE DESCRIPTION DES DESSINS Les concepts fondamentaux de l'invention venant d'être évoqués ci-dessus dans leur forme la plus élémentaire, d'autres caractéristiques et d'autres avantages de la présente invention ressortiront plus clairement à la lecture de la description qui suit, donnant à titre d'exemple non limitatif et en regard des dessins annexés, un mode de réalisation d'un lit équipé d'un dispositif d'escamotage permettant de mettre en oeuvre le procédé d'escamotage utilisant un mouvement de coulissement vertical. Sur ces dessins : La figure 1 est une vue en perspective partiellement éclatée d'un lit équipé du susdit procédé d'escamotage selon l'invention. La figure 2 est une vue en perspective d'une pièce équipée du lit de la figure en position escamotée. La figure 3 est une vue en perspective d'une pièce équipée du lit de la figure en position de couchage. DESCRIPTION DES MODES DE REALISATION PREFERES Tel qu'illustré sur les dessins des figures 1, 2 et 3, le lit de l'invention, référencé 100 dans son ensemble, se compose d'un châssis à lattes (avec une traverse centrale formant raidisseur) faisant office de sommier 110 et dont la face supérieure tournée vers le plafond (non représenté) de la pièce dans laquelle le lit 100 est installé, reçoit un matelas non représenté que recouvrent d'autres articles de literie comme le drap, la couverture, ou la couette pour isoler l'homme du matelas. Selon la disposition principale de l'invention illustrée plus en détails sur le dessin de la figure 1, le châssis-sommier 110 du lit 100 coopère avec un dispositif d'escamotage constitué par un appareil de levage 200 permettant, selon un axe vertical au plan du plafond et/ou du sol, d'élever (flèche E orienté vers le plafond) et de suspendre ledit châssis 110 au plafond dans un plan supérieur proche de ce dernier et dans lequel il est représenté sur des figures 1 et 2, ceci afin de libérer au-dessous le volume qu'il occupait dans la pièce à des fins d'utilisation pleine et entière du dessus de la table 310 d'un bureau de travail 300 situé en dessous. Le même appareil de levage 200 permet également de redescendre (sens de la flèche C orienté vers le sol de la figure 3) le châssis-sommier 110 dans un plan horizontal inférieur pour définir une position horizontale d'utilisation dite de couchage mais surélevée par rapport au sol de manière à toujours dégager en dessous un logement suffisamment haut pour laisser en place la table 310 du bureau de travail 300 avec divers accessoires de travail posés dessus (ordinateur, lampe de bureau, dossiers, bouteilles, etc.... ) . Comme montré sur le dessin de la figure 1, l'appareil de levage 200 est notamment constitué par un ensemble de guidage permettant de monter (flèche E) ou de descendre (flèche C) le châssis-sommier 110 du lit 100 librement coulissant selon un axe vertical entre le sol et le plafond de la pièce et par un ensemble de compensation équilibrant les efforts nécessaires pour assurer le levage (flèche E) du châssis-sommier 110 vers sa position haute escamotée. L'ensemble de guidage se compose de deux paires de rails 210a, 211a et 210b, 211b dressés entre le sol et le plafond de part et d'autre des deux côtés latéraux 110a et 110b formés par les deux traverses de la tête et du pied de lit du châssis-sommier 110, pour définir un chemin de roulement ou de glissement du châssis 110 (selon le mouvement de coulissement des flèches C et E) du châssis- sommier 110 d'une position inférieure de couchage (illustrée à la figure 3) vers une position supérieure escamotée (telle qu'illustrée aux figures 1 et 2) et vice versa. L'ensemble de compensation est constitué, quant à lui, par deux systèmes de contrepoids 220a et 220b qui, formant un ensemble plus lourd que le poids du lit (100) coulissant et disposés derrière chaque côté latéral du châssis-sommier 110, sont reliés aux deux traverses 110a et 110b du châssis-sommier 100 par un dispositif classique de câbles et de poulies de renvoi, équilibrent les efforts nécessaires pour assurer le levage (flèche E) du châssis-sommier 110 vers sa position haute escamotée. Ainsi, avantageusement, l'intervention humaine se limite à une personne pour l'escamotage en position de rangement ou pour l'abaissement en position de couchage, alors qu'auparavant le déménagement d'un lit dans une autre pièce nécessitait l'intervention d'au moins deux personnes. Selon un mode de réalisation préférentielle de l'invention, les parties hautes et basses des deux paires de rails sont habillées deux à deux par deux caissons latéraux bas 230a et 230b dressés à partir du sol de la pièce et deux caissons latéraux hauts 240a et 240b partant du plafond lesquels caissons, habillant les parties basse et haute des quatre rails de guidage 210a, 211a et 210b, 211b, sont d'une profondeur débordante vers l'intérieur du châssis-sommier 110 de manière à ce que les faces supérieures 230a' et 230b' des caissons bas 230a et 230b et les faces inférieures 240a' et 240b' des caissons hauts 240a et 240b fassent office de butées de fin de course bas et haut des déplacements coulissants (flèche C et flèche E respectivement) du châssis-sommier 110 du lit 100. Les demandeurs ont également prévu la mise en place d'un dispositif de réglage du maintien du plan d'horizontalité du châssis-sommier 110 lors de ses déplacements coulissants (flèches C et E). A cet effet, ce dispositif de réglage est constitué de deux systèmes stabilisateurs qui, logés dans des caissons longitudinaux 260c et 260d fixés de manière suspendus au plafond à l'aplomb des montants longitudinaux avant 110c et arrière HOd dudit châssis-sommier 110, sont constitué chacun par un câble sans fin entraîné de manière croisée autour de deux poulies de renvoi calées sur les deux axes supérieurs des poulies de renvoi des deux systèmes de contrepoids 220a et 220b du dispositif de compensation. Avantageusement, ces câbles croisés sont disposés indépendants l'un de l'autre du côté gauche et du côté droit de manière à assurer une sécurité du maintien du plan d'horizontalité lors de la descente (flèche C) du châssis-sommier 110, en cas de rupture de l'un des deux câbles . Bien évidemment, les différentes opérations d'élévation, de suspension, et d'abaissement du châssis- sommier 110 du lit 100 de l'invention pourront être assumées par un moteur électrique actionnant l'appareil de levage 200 et commandable à distance. On comprend que le lit avec son dispositif d'escamotage, qui vient d'être ci-dessus décrit et représenté, l'a été en vue d'une divulgation plutôt que d'une limitation. Bien entendu, divers aménagements, modifications et améliorations pourront être apportés à l'exemple ci-dessus, sans pour autant sortir du cadre de l'invention pris dans ses aspects et dans son esprit les plus larges. Ainsi par exemple: - un meuble-escalier de rangement 400 pourra être installé à demeure près du lit 100 pour faciliter l'accès à ce dernier en position de couchage, - une poignée de blocage 120 associée au longeron apparent 110c du châssis-sommier 110 du lit 100 permettra comme le système connu de crémone (deux tringles métalliques maneuvrables ) de verrouiller le déplacement coulissant du châssis-sommier 110 en position basse de couchage du lit 100, - des organes (patins glissants du type "Téflon", etc..) seront judicieusement aménagés pour limiter les forces de frottement du châssis-sommier 110 le long des rails de guidage 210a, 211b, 211a, 211b, - un chevet avec applique en tête de lit sera fixé sur la paroi à hauteur convenable lorsque le lit est en position de couchage, - un garde-corps 250 de part et d'autre du lit sera fixé au longeron apparent 110c tout en laissant un passage libre pour accéder au lit du côté du meuble-escalier de rangement 400 et en laissant un accès au chevet venant d'être évoqué, - les caisson d'habillage latéraux 230a, 230b, 240a et 240b et longitudinaux 260c et 260d seront démontables pour accéder facilement aux divers mécanismes des dispositifs de guidage, de compensation et de réglage d'horizontalité, ™ 6 C * • • FIELD OF APPLICATION OF THE INVENTION The present invention relates to the field of furniture and / or interior design and relates more precisely to a method and a device making it possible to retract a bed for the purposes of arrangement and storage. . DESCRIPTION OF THE PRIOR ART A bed conventionally consists of a base which, most often formed of four feet, provides the raised seat of a horizontal frame on which one can deposit a mattress covered by other bedding articles. like the sheet, the blanket, or the duvet, in particular to isolate the man from the mattress. Many efforts have been developed in recent years in order to give the beds an aesthetic character, often respecting the evolution of society while being dependent on the spirit of their innovators. Efforts have also focused on different embodiments of beds generally aimed at modifying their structure and / or their destination in order to assume various positions and / or functions or even to improve the comfort of the seated people. However, in rooms called upon to gather in a minimum of space a certain number of elements both those necessary for furnishing for storage, work and sleeping necessarily integrating a bed as those relating to the installations and devices intended for the care cleanliness and preparation and / or meal, it has often been found that the beds in this type of room are permanently installed, prohibiting ipso facto the use of the floor space of the room occupied by the bed for other purposes. Also, when becomes necessary to free space from the location of the room taken by the bed, to date there are only two alternatives. The first alternative is that of "communicating vessels" which consists of "emptying" the room in question while "filling" a neighboring room and vice versa. This alternative therefore requires light structures which are more particularly intended for removable beds, often called extra beds, such as the camp bed essentially consisting of a foldable frame furnished with straps or a large canvas serving as a box spring and mattress. . The second alternative is the retractable bed which consists in pivoting said bed on one of its sides preferably on its lateral side of the headboard so as to be able to draw it up parallel to one of the walls to which it will be retained in this position. once erected by maneuvering it from the other lateral side of the footboard so as to cause the said bed to rock. These two alternatives have the major drawback of being restrictive because they only release a free space on the temporary floor which must be necessarily fitted out and moved quickly from the elements necessary for another use between two successive bed uses of the bed. . It is therefore not conceivable to leave permanently other elements which must also be stored in another location in the room or in another room (hence the term "communicating" vases) when the bed is in position Sleeping. The seat of the bed in the first alternative is folded and in the second tilted from a horizontal position to a vertical position and vice versa, which requires completely rebuilding the bed after each manipulation. In addition, the fact of using light and discreet structures so that said beds are easily concealed in the storage position cannot contribute to good bedding quality. DESCRIPTION OF THE INVENTION On the basis of this state of affairs and of a predetermined specification, the applicants have carried out research which has resulted in an original concept of bed which, while obviating all of the aforementioned drawbacks, makes it possible to free up one's location on the floor in a room without being forced to go out and / or move the fitted bed to another space. To do this, the applicants have devised an original process for retracting a bed of the type of a frame forming a box spring supporting a mattress and carried by a base. This method of the type that makes it possible to move the bed from a horizontal position of use known as sleeping towards a retracting position known as storage and vice versa is, according to the invention, remarkable in that it consists in arrange the frame of said bed in the sleeping position in a horizontal plane raised above the ground so as to release below, a housing high enough to receive other furnishing elements and / or work facilities to equip the room in addition to said bed. The great advantage of such a retraction process is therefore that it makes it possible to have a bed which, in the sleeping position, keeps its location completely free on the ground so that it can dedicate the permanent installation of a other furnishings or appliances. Thus, for example, it will be wise and it is one of the main interior design preferences proposed by the applicants, to provide for the installation of a table for a work desk which very often occupies substantially the same surface area. floor space than a bed. This layout is particularly interesting, particularly in university student rooms with very small dimensions but where the architect-designer is now increasingly asked to compose for bring together in a minimum floor space (about 9 m2) all sanitary equipment (shower, sink, Water-Closet), preparation and meal (kitchenette, table and chairs), storage (shelves, cupboards, wardrobe ) and work (office, computer, telephone), etc. Starting from the fact that a student room occupies a floor area of approximately 9 m2 with a furnished reservation of less than half and that the bed occupies at least one surface of the order of 1.80 m2, the retraction method of the invention therefore makes it possible to envisage obtaining a space saving of almost 40% which can thus be filled with other equipment. Another advantage of the invention in addition to that essential of the aforementioned gain in space resides in the fact that the bed which is rarely an aesthetic piece of furniture in rooms of the studio or student bedroom type where moreover order is not often the first quality of its inhabitant, can be hidden from view thanks to the retraction process which retains its primary function here. The invention provides various embodiments of the method of retracting a bed. A first embodiment consists in retracting the bed by a vertical movement of the chassis towards a storage position located in a plane parallel to the plane of the sleeping position at a height sufficient to clear a free working space above the elements of furniture and / or work installation to authorize their use. For example, and as will be seen in a little more detail in the description supported by the drawings, the chassis of the aforesaid bed may evolve from a retracted storage position to a sleeping position of use by a vertical sliding movement. Another embodiment consists in retracting said bed by a horizontal movement of the chassis towards a storage position located in the same horizontal plane. as that of the sleeping position at a height sufficient to thus free up to the ceiling a free working space above the furnishing elements and / or work installation to authorize their use. For example, the chassis of the aforesaid bed may evolve from a retracted storage position to a sleeping use position either by a horizontal pivoting movement or by a horizontal sliding movement. BRIEF DESCRIPTION OF THE DRAWINGS The fundamental concepts of the invention which have just been mentioned above in their most basic form, other characteristics and other advantages of the present invention will emerge more clearly on reading the description which follows , giving by way of nonlimiting example and with regard to the appended drawings, an embodiment of a bed equipped with a retraction device making it possible to implement the retraction method using a vertical sliding movement. In these drawings: FIG. 1 is a partially exploded perspective view of a bed equipped with the above-mentioned retraction method according to the invention. Figure 2 is a perspective view of a room with the bed of the figure in the retracted position. Figure 3 is a perspective view of a room with the bed of the figure in the sleeping position. DESCRIPTION OF THE PREFERRED EMBODIMENTS As illustrated in the drawings of Figures 1, 2 and 3, the bed of the invention, referenced 100 as a whole, consists of a slatted frame (with a central cross member forming a stiffener) acting as a bed base 110 and whose upper face facing the ceiling (not shown) of the room in which the bed 100 is installed, receives a not shown mattress which covers other bedding items such as a sheet, blanket, or quilt to insulate the man from the mattress. According to the main arrangement of the invention illustrated in more detail in the drawing of Figure 1, the box spring 110 of the bed 100 cooperates with a retraction device consisting of a lifting device 200 allowing, along a vertical axis to the plane from the ceiling and / or from the ground, to raise (arrow E oriented towards the ceiling) and to suspend said chassis 110 from the ceiling in an upper plane close to the latter and in which it is shown in FIGS. 1 and 2, this in order to to release below the volume he occupied in the room for full and complete use of the table top 310 of a work desk 300 located below. The same lifting device 200 also makes it possible to descend (direction of the arrow C oriented towards the ground of FIG. 3) the box spring 110 in a lower horizontal plane to define a horizontal position of use known as sleeping but raised relative to on the ground so as to always leave a slot below it high enough to leave in place the table 310 of the work desk 300 with various work accessories placed on it (computer, desk lamp, files, bottles, etc.). As shown in the drawing of FIG. 1, the lifting device 200 is in particular constituted by a guide assembly making it possible to raise (arrow E) or descend (arrow C) the box spring 110 of the bed 100 freely sliding in a vertical axis between the floor and the ceiling of the room and by a compensation set balancing the forces necessary to ensure the lifting (arrow E) of the box spring 110 towards its high retracted position. The guide assembly consists of two pairs of rails 210a, 211a and 210b, 211b erected between the ground and the ceiling on either side of the two lateral sides 110a and 110b formed by the two crosspieces of the head and footboard of the bed frame 110, to define a rolling or sliding path of the frame 110 (according to the sliding movement of the arrows C and E) of the bed frame 110 d 'a lower sleeping position (illustrated in Figure 3) to a retracted upper position (as illustrated in Figures 1 and 2) and vice versa. The compensation assembly consists, for its part, of two counterweight systems 220a and 220b which, forming an assembly heavier than the weight of the sliding bed (100) and arranged behind each lateral side of the bed frame 110, are connected at the two crossmembers 110a and 110b of the bed frame 100 by a conventional device of cables and return pulleys, balance the forces necessary to ensure the lifting (arrow E) of the bed frame 110 towards its high retracted position. Thus, advantageously, human intervention is limited to one person for the retraction in the storage position or for the lowering in the sleeping position, whereas before moving a bed to another room required the intervention of 'at least two people. According to a preferred embodiment of the invention, the upper and lower parts of the two pairs of rails are dressed two by two by two low side boxes 230a and 230b erected from the floor of the room and two high side boxes 240a and 240b starting from the ceiling which boxes, covering the lower and upper parts of the four guide rails 210a, 211a and 210b, 211b, are of a depth projecting inwardly of the box spring 110 so that the upper faces 230a ' and 230b 'of the bottom boxes 230a and 230b and the lower faces 240a' and 240b 'of the top boxes 240a and 240b act as bottom and top limit stops for sliding movements (arrow C and arrow E respectively) of the bed frame 110 of the bed 100. The applicants have also provided for the installation of a device for adjusting the maintenance of the horizontal plane of the bed frame 110 during its sliding movements ( arrows C and E). To this end, this adjustment device is made up of two stabilizing systems which, housed in longitudinal boxes 260c and 260d fixed in a manner suspended from the ceiling directly above the front longitudinal posts 110c and rear HOd of said frame-frame 110, are made up each by an endless cable driven crosswise around two deflection pulleys wedged on the two upper axes of the deflection pulleys of the two counterweight systems 220a and 220b of the compensation device. Advantageously, these crossed cables are arranged independent of each other on the left side and on the right side so as to ensure security in maintaining the horizontal plane during the descent (arrow C) of the bed frame 110, breakage of one of the two cables. Obviously, the various lifting, suspension and lowering operations of the bed frame 110 of the bed 100 of the invention can be carried out by an electric motor actuating the lifting device 200 and remotely controllable. It is understood that the bed with its retracting device, which has just been described and shown above, has been for disclosure rather than limitation. Of course, various arrangements, modifications and improvements could be made to the above example, without going beyond the ambit of the invention taken in its broadest aspects and spirit. So for example: - a storage staircase 400 could be permanently installed near the bed 100 to facilitate access to the latter in the sleeping position, - a locking handle 120 associated with the apparent spar 110c of the bed frame 110 of the bed 100 will allow, like the known system of cremone bolt (two metal rods maneuverable) to lock the sliding movement of the bed frame 110 in the low bed position 100, - members (sliding pads of the "Teflon" type, etc.) will be judiciously arranged to limit the frictional forces of the bed frame 110 along the guide rails 210a, 211b, 211a, 211b, - a bedside table with headboard sconce will be fixed to the wall at a suitable height when the bed is in the sleeping position, - a handrail 250 on both sides and on the other side of the bed will be fixed to the visible spar 110c while leaving a free passage to access the bed from the side of the storage staircase 400 and leaving access to the bedside just mentioned, - the caissons of ha lateral billing 230a, 230b, 240a and 240b and longitudinal 260c and 260d will be removable for easy access to the various mechanisms of the guidance, compensation and horizontal adjustment devices, ™ 6 C * • •
