Description

La présente invention concerne un élément de mobilier formant lit et bureau.The present invention relates to a piece of furniture forming bed and desk.

Ce type d'élément de mobilier est convertible entre une première position d'utilisation du bureau et de non utilisation du lit et une seconde position d'utilisation du lit et de non utilisation du bureau.This type of furniture item is convertible between a first position of use of the office and non-use of the bed and a second position of use of the bed and non-use of the office.

Le document EP 1 434 507 décrit un élément de mobilier comportant un châssis sur lequel est monté pivotant un lit autour d'un axe horizontal solidaire du lit entre une position de non utilisation verticale et une position d'utilisation horizontale. L'élément de mobilier comporte un bureau relié aux châssis de ce dernier et au lit par des moyens de liaison conformés en parallélogramme déformable et agencés pour maintenir le bureau horizontal durant son déplacement entre un position d'utilisation horizontale éloigné du sol et une position de non utilisation horizontale proche du sol. L'élément de mobilier comporte en outre des moyens de transmission agencés pour déplacer le lit de sa position d'utilisation à sa position de non utilisation durant le déplacement du bureau de sa position de non utilisation à sa position d'utilisation et réciproquement.The document EP 1 434 507 discloses a furniture element comprising a frame on which is pivotally mounted a bed about a horizontal axis secured to the bed between a vertical non-use position and a horizontal use position. The furniture element comprises a desk connected to the frame of the latter and to the bed by deformable parallelogram shaped connecting means and arranged to maintain the horizontal desk during its movement between a horizontal position of use away from the ground and a position of no horizontal use near the ground. The furniture element further comprises transmission means arranged to move the bed from its use position to its non-use position during the movement of the office from its non-use position to its use position and vice versa.

L'élément de mobilier décrit dans ce document assure un déplacement sensiblement horizontal du bureau entre ses positions d'utilisation et de non utilisation. Ainsi, durant le déplacement du bureau, les éléments reposant sur ce dernier restent sensiblement stables et ne sont donc peu susceptibles de tomber sur le sol ou de se renverser. Il en résulte qu'il n'est pas nécessaire de retirer les éléments reposant sur le bureau pour utiliser l'élément de mobilier en tant que lit ou en tant que bureau. De ce fait, la conversion de l'élément de mobilier en lit ou en bureau est simplifiée.The item of furniture described in this document provides a substantially horizontal movement of the office between its positions of use and non-use. Thus, during the movement of the office, the elements resting on the latter remain substantially stable and are therefore unlikely to fall on the ground or overturn. As a result, it is not necessary to remove the desk-top elements to use the furniture item as a bed or as an office. As a result, the conversion of the furniture item into a bed or an office is simplified.

Toutefois, le fait que le lit soit monté pivotant sur le châssis de l'élément de mobilier a pour conséquence, qu'en position de non utilisation, le lit est éloigné du sol. Il en résulte un important encombrement en hauteur de l'élément de mobilier en position d'utilisation du bureau.However, the fact that the bed is pivotally mounted on the frame of the furniture element has the consequence that in the non-use position, the bed is away from the ground. This results in a significant height of the height of the furniture element in the use position of the office.

Cet encombrement vertical est désavantageux, notamment lorsque l'on souhaite prévoir des étagères intégrées disposées au dessus du bureau et du lit.This vertical space is disadvantageous, especially when it is desired to provide integrated shelves arranged above the desk and the bed.

De plus, la cinématique de déplacement du bureau et du lit de ce type d'élément de mobilier limite la profondeur possible du bureau.In addition, the movement kinematics of the office and bed of this type of furniture element limits the possible depth of the office.

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these disadvantages.

Le problème technique à la base de l'invention est donc la réalisation d'un élément de mobilier formant lit et bureau convertible de structure simple, présentant une grande compacité en hauteur, tout en assurant une profondeur de bureau satisfaisante et une grande sécurité d'utilisation.The technical problem underlying the invention is therefore the realization of a piece of furniture forming bed and convertible desk of simple structure, having a high compactness in height, while ensuring a satisfactory office depth and high security of use.

A cet effet, l'invention concerne un élément de mobilier formant bureau et lit convertible entre une première position d'utilisation du bureau et de non utilisation du lit et une seconde position d'utilisation du lit et de non utilisation du bureau, l'élément de mobilier comportant un châssis auquel est relié le bureau par des moyens de liaison conformés en parallélogramme déformable disposés à au moins une extrémité du bureau et agencés pour maintenir le bureau horizontal durant son déplacement entre les première et seconde positions, le lit étant mobile en rotation autour d'un axe horizontal entre une position de non utilisation verticale et une position d'utilisation horizontale, l'élément de mobilier comportant des moyens de transmission agencés pour déplacer le lit de sa position d'utilisation à sa position de non utilisation durant le déplacement du bureau de sa position de non utilisation à sa position d'utilisation et réciproquement, caractérisé en ce que l'axe de rotation du lit est mobile en translation verticale par rapport au châssis de l'élément de mobilier entre une position basse à proximité du sol lorsque le lit est en position de non utilisation et une position haute éloignée du sol lorsque le lit est en position d'utilisation.For this purpose, the invention relates to a piece of office furniture and convertible bed between a first position of use of the office and non-use of the bed and a second position of use of the bed and non-use of the office, the furniture element comprising a frame to which the office is connected by deformable parallelogram shaped connecting means arranged at at least one end of the office and arranged to maintain the horizontal desk during its movement between the first and second positions, the bed being movable in rotation about a horizontal axis between a vertical non-use position and a horizontal use position, the furniture element comprising transmission means arranged to move the bed from its use position to its non-use position during moving the desk from its non-use position to its use position and vice versa, characterized in that e that the axis of rotation of the bed is movable in vertical translation relative to the frame of the furniture element between a low position close to the ground when the bed is in the non-use position and a high position remote from the ground when the bed is in use position.

Ainsi, compte tenu de la mobilité en translation verticale de l'axe de rotation du lit, en position de non utilisation, le lit se trouve dans une position verticale à proximité du sol. Il en résulte donc un faible encombrement en hauteur du lit lorsque ce dernier se trouve en position de non utilisation. L'élément de mobilier selon l'invention présente de ce fait une grande compacité en hauteur.Thus, given the mobility in vertical translation of the axis of rotation of the bed, in the non-use position, the bed is in a vertical position close to the ground. This results in a small footprint in height of the bed when the latter is in the non-use position. The furniture element according to the invention thus has a great compactness in height.

Avantageusement, les moyens de transmission comportent une patte dont l'une des extrémités est solidaire d'un élément mobile du parallélogramme déformable et dont l'autre extrémité est montée pivotante autour d'un axe horizontal solidaire du lit.Advantageously, the transmission means comprise a tab whose one end is secured to a movable member of the deformable parallelogram and the other end is pivotally mounted about a horizontal axis integral with the bed.

La liaison solidaire entre la patte et un élément mobile du parallélogramme déformable et la liaison pivot entre la patte et le lit permet d'assurer un déplacement du lit entre ses positions d'utilisation et de non utilisation durant un déplacement du bureau entre ses positions de non utilisation et d'utilisation.The integral connection between the tab and a movable member of the deformable parallelogram and the pivot connection between the tab and the bed ensures a displacement of the bed between its use positions and non use during a movement of the office between its positions of non-use and use.

Selon une autre caractéristique de l'invention, les moyens de liaison conformés en parallélogramme déformable comportent des première et seconde bielles parallèles dont les extrémités sont respectivement montées pivotantes d'une part autour d'axes horizontaux solidaires du bureau et d'autre part autour d'axes horizontaux solidaires du châssis de l'élément de mobilier, et en ce que l'une des extrémités de la patte est solidaire de l'une des première et seconde bielles.According to another characteristic of the invention, the deformable parallelogram-shaped connecting means comprise first and second parallel rods whose ends are respectively pivotally mounted on the one hand around horizontal axes integral with the desk and on the other hand around horizontal axes integral with the frame of the furniture element, and in that one end of the leg is integral with one of the first and second connecting rods.

Avantageusement, les axes de pivotement des première et seconde bielles solidaires du bureau et solidaires du châssis de l'élément de mobilier sont disposés dans deux plans parallèles.Advantageously, the pivot axes of the first and second connecting rods integral with the office and integral with the frame of the furniture element are arranged in two parallel planes.

Selon une caractéristique avantageuse de l'invention, les deux plans contenant les axes de pivotement des première et seconde bielles sont verticaux.According to an advantageous characteristic of the invention, the two planes containing the pivot axes of the first and second connecting rods are vertical.

Selon encore une autre caractéristique de l'invention, l'élément de mobilier comporte une troisième bielle parallèle et décalées par rapport aux première et seconde bielles dont l'une des extrémités est montée pivotante autour d'un axe horizontal solidaire du bureau et dont l'autre extrémité est montée pivotante autour d'un axe horizontal solidaire du châssis de l'élément de mobilier.According to yet another characteristic of the invention, the furniture element comprises a third connecting rod parallel and offset with respect to the first and second connecting rods, one end of which is pivotally mounted about a horizontal axis integral with the desk and whose Another end is pivotally mounted about a horizontal axis integral with the frame of the furniture element.

La présence de cette troisième bielle assure une parfaite stabilité du bureau d'une part dans ses positions d'utilisation et de non utilisation, et d'autre part durant son déplacement entre ces deux positions.The presence of this third connecting rod ensures perfect stability of the office on the one hand in its positions of use and non-use, and on the other hand during its movement between these two positions.

Ainsi, durant l'utilisation ou le déplacement du bureau, les éléments reposant sur ce dernier restent parfaitement stables et ne sont donc pas susceptibles de tomber sur le sol ou de se renverser.Thus, during the use or movement of the office, the elements resting on the latter remain perfectly stable and are therefore not likely to fall on the ground or overturn.

En outre, cette troisième bielle permet au bureau de supporter des charges élevées, par exemple le poids de deux personnes, lorsqu'il se trouve en position d'utilisation.In addition, this third connecting rod allows the office to support high loads, for example the weight of two people, when in the position of use.

Avantageusement, l'axe de rotation du lit mobile en translation verticale comporte une roulette guidée en translation dans une glissière verticale solidaire du châssis de l'élément de mobilier.Advantageously, the axis of rotation of the moving bed in vertical translation comprises a wheel guided in translation in a vertical slide secured to the frame of the furniture element.

De préférence, l'élément de mobilier comporte un système de verrouillage automatique dans les première et seconde positions de l'élément de mobilier.Preferably, the furniture element comprises an automatic locking system in the first and second positions of the furniture element.

Ainsi, l'utilisateur n'a pas besoin de verrouiller manuellement le lit ou le bureau dans sa position d'utilisation. De ce fait, les risques liés à un oubli de verrouillage du lit ou du bureau de la part de l'utilisateur sont supprimés. Le système de verrouillage automatique assure donc une parfaite sécurité d'utilisation de l'élément de mobilier.Thus, the user does not need to manually lock the bed or desk in its position of use. As a result, the risks associated with forgetting the lock of the bed or the desk by the user are eliminated. The automatic locking system thus ensures perfect safety of use of the furniture element.

Il doit être noté que chaque système de verrouillage comporte un ressort de rappel 39 agencé pour définir deux positions d'équilibre stables de l'élément de verrouillage respectif, ces deux positions correspondant aux positions de verrouillage et de déverrouillage de l'élément de verrouillage.It should be noted that each locking system comprises a return spring 39 arranged to define two stable equilibrium positions of the respective locking element, these two positions corresponding to the locking and unlocking positions of the locking element.

Chaque système de verrouillage comporte en outre une poignée de déverrouillage manuel 41 solidaire de l'élément de verrouillage respectif agencée pour permettre à un utilisateur de déplacer l'élément de verrouillage 33 de sa position de verrouillage à sa position de déverrouillage.Each locking system further comprises a manual unlocking handle 41 integral with the respective locking element arranged to allow a user to move the locking member 33 from its locking position to its unlocking position.

Chaque élément de verrouillage 33 comporte un galet de verrouillage 42 agencé pour coopérer avec la traverse supérieure 9 de la structure latérale respective 4 durant le déplacement du lit entre ses positions d'utilisation et de non utilisation afin de faire passer automatiquement l'élément de verrouillage de sa position de déverrouillage à sa position de verrouillage.Each locking element 33 comprises a locking roller 42 arranged to cooperate with the upper cross member 9 of the respective lateral structure 4 during the displacement of the bed between its positions of use and non-use in order to automatically pass the locking element. from its unlocking position to its locking position.

L'élément de mobilier comporte également, au niveau de chaque structure latérale, un vérin pneumatique 43 dont l'une des extrémités est montée pivotante autour d'un axe horizontal 44 solidaire de la patte respective 26 et dont l'autre extrémité est montée pivotante autour d'un axe horizontal 45 solidaire de la structure latérale respective 4.The furniture element also comprises, at each lateral structure, a pneumatic cylinder 43, one end of which is pivotally mounted about a horizontal axis 44 integral with the respective tab 26 and the other end of which is pivotally mounted. around a horizontal axis 45 secured to the respective lateral structure 4.

L'utilisation de l'élément de mobilier va maintenant être décrite.The use of the furniture element will now be described.

En position d'utilisation du bureau 11, comme représentée aux figures 1 et 2, le lit 22 est en position verticale de non utilisation et les éléments de verrouillage 33 se trouvent dans leur position de verrouillage. De ce fait, il est impossible de déplacer le bureau par rapport au lit. L'utilisateur peut donc se servir du bureau et prendre appui sur ce dernier.In the position of use of the desk 11, as shown in Figures 1 and 2, the bed 22 is in the vertical position of non-use and the locking elements 33 are in their locking position. As a result, it is impossible to move the desk relative to the bed. The user can therefore use the office and build on it.

Lorsque l'utilisateur souhaite utiliser l'élément de mobilier comme lit, il doit tout d'abord déverrouiller le bureau.When the user wants to use the furniture element as a bed, he must first unlock the desk.

Pour cela, il actionne les poignées 41 des deux systèmes de verrouillage 32 de sorte à faire pivoter chaque élément de verrouillage 33 dans sa position de déverrouillage, comme cela est représenté aux figures 4 à 6. Il doit être noté que chaque élément de verrouillage est maintenu dans sa position de déverrouillage par le ressort de rappel respectif 39.For this, it actuates the handles 41 of the two locking systems 32 so as to rotate each locking member 33 in its unlocking position, as shown in Figures 4 to 6. It should be noted that each locking element is maintained in its unlocking position by the respective return spring 39.

Le passage de chaque élément de verrouillage 33 dans sa position de déverrouillage libère la première encoche de chaque élément de verrouillage de la première tige respective 35. Il en résulte que le bureau n'est plus verrouillé, il peut donc être déplacé de sa position d'utilisation vers sa position de non utilisation.The passage of each locking member 33 in its unlocking position releases the first notch of each locking element of the respective first rod 35. As a result, the desk is no longer locked, so it can be moved from its position to use to its non-use position.

Afin de déplacer le bureau dans sa position de non utilisation, l'utilisateur exerce une poussée dirigée vers le bas sur la face supérieure du bureau. Ceci entraîne un pivotement des bielles 13, 14 de chaque parallélogramme déformable 12 et également des troisième bielles 28 autour des axes ménagés sur les première et seconde pièces en forme de L respectives 19, 21.In order to move the desk to its non-use position, the user pushes downward on the upper face of the desk. This causes pivoting of the connecting rods 13, 14 of each deformable parallelogram 12 and also of the third connecting rods 28 around the shafts provided on the first and second respective L-shaped pieces 19, 21.

Le pivotement de ces différentes bielles entraîne un pivotement des deux pattes 26 autour des axes solidaires du lit et une compression des deux vérins pneumatiques 43. Il doit être noté que les deux pattes 26 sont reliées l'une à l'autre par une traverse 46 agencée pour assurer une synchronisation des mouvements de chaque patte.The pivoting of these different rods causes pivoting of the two tabs 26 around the integral axes of the bed and a compression of the two pneumatic cylinders 43. It should be noted that the two tabs 26 are connected to each other by a cross member 46. arranged to ensure a synchronization of the movements of each leg.

Le pivotement de chaque patte 26 entraîne dans un premier temps un coulissement vertical vers le haut des roulettes de guidage et de stabilité 25 dans la glissière respective 23 permettant ainsi la libération de chaque roulette de stabilité de la glissière respective, et dans un second temps un coulissement vertical vers le haut de la roulette de guidage accompagné d'un pivotement du lit autour de l'axe A de la roulette de guidage.The pivoting of each lug 26 initially causes vertical sliding upwards of the guiding and stability rollers 25 in the respective slideway 23 thus allowing the release of each stability roller of the respective slide, and in a second step a vertical sliding up the guide wheel accompanied by a pivoting of the bed about the axis A of the guide wheel.

A ce moment, le matelas 47 est maintenu sur le lit par l'intermédiaire de quatre systèmes de maintien 48 disposés aux quatre coins du lit.At this time, the mattress 47 is held on the bed by means of four holding systems 48 arranged at the four corners of the bed.

Comme représenté à la figure 7, en continuant la descente du bureau 11 et donc le pivotement du lit 22, le galet de verrouillage 42 de chaque système de verrouillage vient au contact de la traverse supérieure 9 de la structure latérale respective 4 et coopère avec cette dernière afin de ramener automatiquement l'élément de verrouillage respectif 33 dans sa position de verrouillage à l'aide du ressort de rappel 39.As shown in FIG. 7, while continuing the descent of the desk 11 and thus the pivoting of the bed 22, the locking roller 42 of each locking system comes into contact with the upper cross member 9 of the respective lateral structure 4 and cooperates with this last in order to automatically return the respective locking element 33 to its locking position by means of the return spring 39.

Lorsque le bureau atteint sa position de non utilisation, comme montré aux figures 8 et 9, le lit se trouve dans sa position d'utilisation horizontale et la seconde encoche 36 de chaque élément de verrouillage coopère avec la seconde tige respective 37 afin d'assurer un verrouillage automatique du lit.When the desk reaches its non-use position, as shown in Figures 8 and 9, the bed is in its horizontal use position and the second notch 36 of each locking member cooperates with the respective second rod 37 to ensure an automatic locking of the bed.

L'utilisateur peut donc utiliser l'élément de mobilier comme lit sans avoir besoin de déplacer manuellement les éléments de verrouillage 33 dans leur position de verrouillage.The user can therefore use the furniture element as a bed without having to manually move the locking elements 33 into their locking position.

Dans cette position d'utilisation du lit, chaque galet de déverrouillage 42 prend appui sur la traverse intermédiaire respective 8 afin d'assurer la stabilité du lit. En outre, dans cette position du lit, chaque vérin pneumatique 43 est complètement comprimé.In this use position of the bed, each unlocking roller 42 bears on the respective intermediate cross member 8 so that to ensure the stability of the bed. In addition, in this position of the bed, each pneumatic cylinder 43 is completely compressed.

Lorsque l'utilisateur souhaite réutiliser l'élément de mobilier comme bureau, il doit d'abord déverrouiller le lit.When the user wants to reuse the furniture element as an office, he must first unlock the bed.

Pour cela, il actionne manuellement les poignées de déverrouillage 41 des deux systèmes de verrouillage 32 de sorte à faire pivoter les éléments de verrouillage 33 dans leur position de déverrouillage.For this, it manually actuates the release handles 41 of the two locking systems 32 so as to rotate the locking elements 33 in their unlocking position.

Comme montré à la figure 10, le passage de chaque élément de verrouillage dans sa position de déverrouillage libère la seconde encoche 36 de chaque élément de verrouillage de la seconde tige respective 37. Il en résulte que le lit n'est plus verrouillé, il peut donc être déplacé de sa position d'utilisation vers sa position de non utilisation.As shown in FIG. 10, the passage of each locking element in its unlocking position frees the second notch 36 of each locking element of the respective second rod 37. As a result, the bed is no longer locked, it can therefore be moved from its use position to its non-use position.

Afin de déplacer le lit vers sa position de non utilisation, l'utilisateur soulève le bord avant du lit, ce soulèvement étant facilité par la décompression de chaque vérin pneumatique 43. Ceci entraîne un pivotement des deux pattes 26 et donc des différentes bielles. Il en résulte d'une part un coulissement vertical vers le bas de chaque roulette de guidage dans la glissière respective 23 ainsi qu'un pivotement du lit autour des axes A des roulettes de guidage, et d'autre part une remontée du bureau.In order to move the bed to its non-use position, the user raises the front edge of the bed, this lifting being facilitated by the decompression of each pneumatic cylinder 43. This causes a pivoting of the two legs 26 and therefore the different connecting rods. This results firstly a vertical sliding down each guide wheel in the respective slide 23 and a pivoting of the bed about the axes A guide rollers, and secondly a rise of the office.

Comme plus particulièrement montré aux figures 11 et 12, en continuant le déplacement du lit vers sa position de non utilisation, le galet de verrouillage 42 de chaque système de verrouillage 32 vient au contact de la traverse supérieure 9 de la structure latérale respective et coopère avec cette dernière afin de ramener automatiquement l'élément de verrouillage respectif 33 dans sa position de verrouillage à l'aide du ressort de rappel 39.As more particularly shown in Figures 11 and 12, continuing the movement of the bed to its non-use position, the locking roller 42 of each locking system 32 comes into contact with the upper cross member 9 of the respective lateral structure and cooperates with the latter in order to automatically return the respective locking element 33 to its locking position by means of the return spring 39.

Lorsque le lit atteint sa position de non utilisation, chaque roulette de stabilité 25 rentre dans la glissière respective 23 afin d'assurer la stabilité du lit, la première encoche de chaque élément de verrouillage coopère avec la première tige respective 35 afin d'assurer un verrouillage automatique du bureau, et le bureau 11 se retrouve de nouveau dans sa position d'utilisation horizontale.When the bed reaches its non-use position, each stability wheel 25 enters the respective slide 23 to ensure the stability of the bed, the first notch of each locking member cooperates with the respective first rod 35 to ensure a automatic locking of the desk, and the desk 11 is again in its position of horizontal use.

L'utilisateur peut donc utiliser l'élément de mobilier comme bureau sans avoir besoin de déplacer manuellement les éléments de verrouillage dans leur position de verrouillage.The user can therefore use the furniture element as a desk without having to manually move the locking elements into their locking position.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un élément de mobilier formant lit et bureau convertible de structure simple, présentant une grande compacité en hauteur, tout en assurant une profondeur de bureau satisfaisante et une grande sécurité d'utilisation.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a piece of furniture bed and convertible desk of simple structure, having a high compactness in height, while ensuring a satisfactory office depth and high security of use.

Comme il va de soi l'invention ne se limite pas à la forme d'exécution de cet élément de mobilier décrite ci-dessus à titre d'exemple, elle embrasse au contraire toutes les variantes de réalisation.It goes without saying that the invention is not limited to the embodiment of this item of furniture described above by way of example, it embraces on the contrary all variants.

C'est ainsi notamment que l'élément de mobilier pourrait comporter des moyens de motorisation agencés pour permettre un déplacement motorisé du lit ou du bureau entre ses positions d'utilisation ou de non utilisation. Avantageusement, l'élément de mobilier est conçu de telle façon que les moyens de motorisation sont très simples à installer, sans modification de la structure de l'élément de mobilier ou des moyens de liaison ou de transmission. Par exemple, les moyens de motorisation pourraient comprendre un moteur électrique entraînant en rotation une vis sans fin disposée longitudinalement dans la glissière 23 et bloquée en translation par rapport à cette dernière, la vis sans fin entraînant en translation un écrou bloqué en rotation par rapport à la glissière, l'écrou étant relié à l'axe de rotation A du lit.Thus, in particular, the furniture element could include motorization means arranged to allow a motorized movement of the bed or the desk between its positions of use or non-use. Advantageously, the furniture element is designed in such a way that the motorization means are very simple to install, without modifying the structure of the furniture element or connecting or transmission means. For example, the motorization means could comprise an electric motor driving in rotation a worm disposed longitudinally in the slide 23 and locked in translation relative thereto, the worm driving in translation a nut locked in rotation relative to the slide, the nut being connected to the axis of rotation A of the bed.

De plus, le châssis 3, les ossatures du lit et du bureau pourraient être réalisés en acier, en aluminium ou en bois.In addition, the frame 3, the frame of the bed and desk could be made of steel, aluminum or wood.

En outre, les structures latérales 4 pourraient être garnies de panneaux en bois, en matière plastique, en composite ou tout autre matériau.In addition, the side structures 4 could be lined with panels of wood, plastic, composite or any other material.

Selon une autre alternative de l'invention, chaque structure latérale de l'élément de mobilier pourrait être formé uniquement par un panneau en bois, en matière plastique, en composite ou tout autre matériau. Dans ce cas, la glissière 23 serait directement ménagée dans le panneau, et deux rainures de guidage seraient également ménagées dans le panneau afin d'assurer un guidage du galet de verrouillage 42 et de la roulette de stabilité 25.According to another alternative of the invention, each lateral structure of the furniture element could be formed solely by a wooden panel, plastic, composite or any other material. In this case, the slide 23 would be directly formed in the panel, and two guide grooves would also be formed in the panel to ensure a guide of the locking roller 42 and the stability roller 25.

Les figures représentent un lit simple disposé longitudinalement par rapport à l'élément de mobilier. Toutefois, il serait possible de prévoir un lit double disposé transversalement par rapport à l'élément de mobilier. Dans ce cas, un piétement pourrait être prévu sensiblement au niveau de l'extrémité libre du lit afin d'assurer une parfaite stabilité du lit double en position d'utilisation. Il est à noter que le piétement pourrait former une étagère en position de non utilisation du lit.The figures show a single bed arranged longitudinally with respect to the furniture element. However, it would be possible to provide a double bed arranged transversely to the furniture element. In this case, a base could be provided substantially at the free end of the bed to ensure perfect stability of the double bed in the use position.
