La présente invention concerne un dispositif visant au déplacement vertical d'un objet mobilier en vue de son stockage en plafond ou sur le sol dans le but d'une meilleure gestion de l'espace disponible. The present invention relates to a device for the vertical movement of a movable object for its storage on the ceiling or on the floor in order to better manage the available space.
Certains systèmes utilisent le levage à l'aide de câbles s'enroulant à la montée et se déroulant à la descente sur des poulies solidaires d'arbres ou d'axes dynamiques ce qui peut occasionner une accumulation anarchique de l'enroulement de ces câbles, pouvant selon le hasard se chevaucher ou se mettre en parallèle, il en résulte une différence dans la longueur des câbles et par conséquent une horizontalité aléatoire de l'objet ; dans certains cas il peut en résulter une panne majeure due au blocage d'un desdits câbles. Ces mêmes systèmes utilisent des longueurs différentes de câble pour la partie la plus éloignée de l'axe principal, ce qui peut, dans le temps, provoquer des allongements inégaux. Some systems use lifting by means of cables winding up and down taking place on pulleys secured to trees or dynamic axes which can cause an uncontrolled accumulation of the winding of these cables, being able by chance to overlap or be put in parallel, this results in a difference in the length of the cables and consequently a random horizontality of the object; in some cases it may result in a major breakdown due to the blockage of one of said cables. These same systems use different lengths of cable for the part furthest from the main axis, which can, over time, cause unequal elongations.
En général, on ne trouve pas de pieds fixes ou repliables sous ces objets mobiliers, il est alors nécessaire de fournir des points d'appui matérialisés par des volumes de même hauteur. Le dispositif selon l'invention permet de remédier à ces inconvénients, Il comporte en effet selon une première caractéristique, des sangles d'une largeur suffisante qui de par leur tension, s'enroulent perpendiculairement à un axe dynamique en s'additionnant harmonieusement. In general, there are no fixed or folding feet under these movable objects, it is then necessary to provide support points materialized by volumes of the same height. The device according to the invention overcomes these drawbacks. It indeed has, according to a first characteristic, straps of sufficient width which, by their tension, are wound perpendicularly to a dynamic axis by adding together harmoniously.
Selon une deuxième caractéristique deux axes libres de part et d'autre de l'arbre dynamique renvoient les sangles vers les extrémités de l'objet, leur attribuant ainsi une égale longueur. According to a second characteristic, two free axes on either side of the dynamic shaft return the straps to the ends of the object, thus giving them an equal length.
Selon une troisième caractéristique, l'objet mobilier est équipé de quatre pieds escamotables supprimant l'obligation de fournir des points d'appui pour recevoir l'objet. Ces pieds se replient en fin de course sous le plafond. According to a third characteristic, the movable object is equipped with four retractable feet eliminating the obligation to provide support points for receiving the object. These feet fold up at the end of the race under the ceiling.
L'objet, ici matérialisé par un lit, suspendu à ses extrémités par des sangles se déplace de bas en haut et inversement en gardant son horizontalité. En passant sur deux arbres à rotation libre, ces sangles rejoignent pour s'y fixer un arbre central dynamique actionné par un moteur ou un treuil ; selon le sens de rotation, les sangles s'enroulent ou se déroulent soit pour soulever l'objet mobilier et le ranger dans une niche de plafond constituée par un cadre en bois ou en métal, soit pour le descendre sur le sol par l'intermédiaire de pieds escamotables. Le cadre reçoit les trois arbres ainsi que les éléments de guidage ; il constitue en outre un élément de faux plafond et peut recevoir des rallonges de fixation murale. Des pieds tournants sur un axe se mettent en position de repli lorsque l'objet se niche dans le cadre de plafond. Quatre roulettes positionnées aux extrémités de l'objet mobilier permettent un guidage précis lors de leur rencontre avec des cales solidaires de ce même cadre de plafond. The object, here materialized by a bed, suspended at its ends by straps moves from bottom to top and vice versa while keeping its horizontality. Passing over two freely rotating shafts, these straps join to fix a dynamic central shaft actuated by a motor or a winch; depending on the direction of rotation, the straps are wound or unrolled either to lift the movable object and store it in a ceiling niche formed by a wooden or metal frame, or to lower it to the ground via retractable feet. The frame receives the three shafts as well as the guide elements; it also constitutes a false ceiling element and can receive wall fixing extensions. Rotating feet on an axis move into the folded position when the object is nestled in the ceiling frame. Four rollers positioned at the ends of the movable object allow precise guidance during their meeting with wedges integral with this same ceiling frame.

Les dessins annexés illustrent l'invention : La figure 1 représente une vue usuelle latérale. The accompanying drawings illustrate the invention: Figure 1 shows a usual side view.
La figure 2 représente une vue de dessus. Figure 2 shows a top view.
La figure 3 représente une vue en détail d'une roulette de guidage et un des pieds au point de rencontre avec la crémaillère. Figure 3 shows a detailed view of a guide wheel and one of the feet at the point of contact with the rack.
La figure 4 représente une vue en détail d'un des pieds enclenché à fond dans la crémaillère. Figure 4 shows a detailed view of one of the legs fully engaged in the rack.
En référence aux figures 1 et 2, l'objet mobilier est représenté ici par un lit 1 sur lequel quatre sangles 2 sont fixées, ces quatre sangles 2 sont reliées à leur extrémité à un arbre dynamique 3 actionné par un moteur électrique 4, lorsque l'arbre dynamique 3 tourne, les sangles 2 s'enroulent en passant sur les deux arbres libres 5 et soulèvent l'objet mobilier 1 ou le descendent selon la demande. L'objet mobilier 1 pénètre précisément dans le cadre de plafond 9 grâce à huit roulettes 10 fixées aux angles dudit objet mobilier 1 par la rencontre de huit guides 15 solidaires du cadre 9. A la base de l'objet mobilier 1, sont fixés quatre axes 7 sur lesquels quatre pieds 6 pivotent. Ces pieds 6 comprennent, en partie supérieure, une série de dents 16 qui, lorsqu'elles s'engrènent sur quatre crémaillères 8, elles mêmes positionnées sur le cadre 9, déclenchent le positionnement desdits pieds 6 vers la position fermé. Lorsque l'objet mobilier 1 descend, les pieds 6 se redressent en égrenant leurs dents 7 sur la crémaillère 8. Ils sont maintenus ouverts par un ressort 11 dont une extrémité est prise sur un téton 12 solidaire de l'objet mobilier 1 et dont l'autre extrémité est prise sur un téton 13 solidaire du pied 6. Un butoir 14 contribue à maintenir la position du pied 6 en bloquant sa course pivotante. Le poids exercé par l'objet mobilier 1 sur les pieds 6 par rapport au sol et l'angle ouvert de ces pieds 6 confèrent à l'objet 1 une bonne stabilité au sol.With reference to FIGS. 1 and 2, the movable object is represented here by a bed 1 on which four straps 2 are fixed, these four straps 2 are connected at their end to a dynamic shaft 3 actuated by an electric motor 4, when the 'dynamic shaft 3 rotates, the straps 2 are wound by passing over the two free shafts 5 and lift the movable object 1 or lower it as required. The movable object 1 precisely penetrates into the ceiling frame 9 thanks to eight rollers 10 fixed to the angles of the said movable object 1 by the meeting of eight guides 15 secured to the frame 9. At the base of the movable object 1, four are fixed axes 7 on which four feet 6 pivot. These feet 6 comprise, in the upper part, a series of teeth 16 which, when they mesh on four racks 8, themselves positioned on the frame 9, trigger the positioning of said feet 6 towards the closed position. When the movable object 1 descends, the feet 6 straighten out by shelling their teeth 7 on the rack 8. They are held open by a spring 11, one end of which is taken on a stud 12 secured to the movable object 1 and of which the 'other end is taken on a stud 13 secured to the foot 6. A stopper 14 helps to maintain the position of the foot 6 by blocking its pivoting stroke. The weight exerted by the movable object 1 on the feet 6 relative to the ground and the open angle of these feet 6 give the object 1 good stability on the ground.
