Abstract

The device comprises a bed intended to be moved vertically, within a guiding structure, between a low use position and a high storage position. At each corner, the bed carries a pulley 6, 6', 6", 6"' over each of which passes a cord 7, 7', 7", 7"', of which one end is fastened at the top part of the structure. After passing over return pulleys, the free ends of the cords 7, 7', 7", 7"' are fastened to a control handle 9 equipped with a counterweight 21. The step-down hoists formed by the pulleys 6, 6', 6", 6"' and the cords 7, 7', 7", 7"' make it possible to use a counterweight 21 which has a mass substantially less than that of the bed. <IMAGE>

Description

La présente invention concerne un dispositif permettant le déplacement vertical d'un lit à l'intérieur d'une structure et l'immobilisation de celui-ci dans une position haute de rangement libérant ainsi l'espace inférieur.The present invention relates to a device allowing the vertical displacement of a bed inside a structure and the immobilization of the latter in a high storage position, thus freeing up the lower space.

Par le document FR-A-2 616 309 on connaît un dispositif permettant le déplacement vertical d'une plate-forme ou d'un lit à l'intérieur d'une structure. Toutefois la mise-en-oeuvre de ce dispositif nécessite des systèmes de guidage coûteux. De plus, le lit doit être équilibré par un contrepoids d'une masse équivalente à celle du lit, ce qui est coûteux et nécessite un réglage qui doit être remis en cause à chaque modification d'aménagement de la plate-forme.Document FR-A-2 616 309 discloses a device allowing the vertical displacement of a platform or a bed inside a structure. However, the implementation of this device requires costly guidance systems. In addition, the bed must be balanced by a counterweight of a mass equivalent to that of the bed, which is expensive and requires an adjustment which must be called into question each time the layout of the platform is modified.

La présente invention a pour objet de remédier aux inconvénients présentés par les dispositifs connus et elle propose à cet effet un lit à déplacement vertical qui est de conception simple et peu coûteuse, d'un fonctionnement fiable et pratique, et qui ne nécessite pour la commande de son déplacement vertical qu'une force très sensiblement inférieure au poids du lit.The object of the present invention is to remedy the drawbacks presented by known devices and for this purpose it proposes a bed with vertical displacement which is of simple and inexpensive design, of reliable and practical operation, and which does not require for the control of its vertical displacement only a force very significantly less than the weight of the bed.

Selon l'invention, le dispositif comprend au moins deux cordes qui coopèrent chacune vers une extrémité avec un point du lit, qui passent sur des poulies de renvoi portées par la structure de guidage et qui sont associées chacune à son autre extrémité à un moyen de déplacement permettant d'appliquer des tractions auxdites cordes pour assurer l'élévation du lit en position horizontale et inversement, et il se caractérise par l'association, à chacune desdites cordes, d'un palan réducteur assurant une diminution de la force à appliquer audit moyen de déplacement afin d'élever le lit jusqu'à sa position haute. Cette force à appliquer se trouve ainsi divisée par le coefficient de démultiplication des palans.According to the invention, the device comprises at least two cords which each cooperate towards one end with a point of the bed, which pass over deflection pulleys carried by the guide structure and which are each associated at its other end with a means of displacement making it possible to apply pull-ups to said ropes to ensure the elevation of the bed in a horizontal position and vice versa, and it is characterized by the association, with each of said ropes, of a reducing hoist ensuring a reduction in the force to be applied to said means of movement in order to raise the bed to its high position. This force to be applied is thus divided by the coefficient of reduction of the hoists.

Lorsque le moyen de déplacement comprend un contrepoids, la masse du contrepoids est divisée par le coefficient de démultiplication des palans et peut ainsi être inférieure ou égale à la moitié de la masse du lit. Avantageusement, le moyen de déplacement peut être constitué par une poignée à laquelle sont fixées les cordes de levage et sur laquelle s'engage par coulissement et s'appuie un contrepoids amovible.When the displacement means comprises a counterweight, the mass of the counterweight is divided by the gear reduction coefficient of the hoists and can thus be less than or equal to half the mass of the bed. Advantageously, the displacement means can be constituted by a handle to which the lifting ropes are fixed and on which engages by sliding and bears a removable counterweight.

Pour bien faire comprendre le dispositif de lit à déplacement vertical selon l'invention on en décrira ci-après une forme d'exécution préférée et une variante en référence aux dessins schématiques annexés dans lesquels :

  • la figure 1 est une vue perspective d'un lit à déplacement vertical selon l'invention ;
  • la figure 2 est une vue perspective montrant plus particulièrement le système de cordes et de poulies équipant le lit de la figure 1 ;
  • la figure 3 est une vue en coupe verticale du système de contrepoids amovible assurant l'équilibrage du lit à déplacement vertical des figures 1 et 2 ;
  • la figure 4 est une vue perspective du moyen de réglage de l'assiette du lit ; et
  • la figure 5 est une vue perspective d'une variante du lit selon l'invention avec commande du déplacement vertical par un système de treuil à tambour unique.
In order to clearly understand the vertical displacement bed device according to the invention, a preferred embodiment and a variant will be described below, with reference to the appended schematic drawings in which:
  • Figure 1 is a perspective view of a vertical displacement bed according to the invention;
  • Figure 2 is a perspective view showing more particularly the system of ropes and pulleys equipping the bed of Figure 1;
  • Figure 3 is a vertical sectional view of the removable counterweight system ensuring the balancing of the vertical displacement bed of Figures 1 and 2;
  • Figure 4 is a perspective view of the means for adjusting the trim of the bed; and
  • Figure 5 is a perspective view of a variant of the bed according to the invention with control of the vertical movement by a single drum winch system.

En référence plus particulièrement aux figures 1 et 2, on a désigné de façon générale en 1 une structure rigide de guidage à l'intérieur de laquelle est destiné à se déplacer verticalement un lit 2. La structure 1 comprend quatre poutres verticales 3 qui sont assemblées à leur partie supérieure par quatre poutres horizontales 4. Quatre autres poutres horizontales 5, parallèles aux poutres 4 à un niveau inférieur à celles-ci, contribuent à la rigidité de la structure.Referring more particularly to FIGS. 1 and 2, a rigid guide structure has generally been designated at 1, inside which is intended to move a bed 2 vertically. The structure 1 comprises four vertical beams 3 which are assembled at their upper part by four horizontal beams 4. Four other horizontal beams 5, parallel to the beams 4 at a level lower than these, contribute to the rigidity of the structure.

Quatre systèmes de palan sont disposés aux quatre angles de la structure 1, chaque système de palan comprenant une poulie 6, 6', 6", 6"' portée par le lit 2 au voisinage de chaque angle et une corde 7, 7', 7", 7"' passant sur ladite poulie et dont une extrémité est fixée en un point haut 8, 8', 8", 8"' de la structure 1. Les quatre cordes 7, 7', 7", 7"' sont renvoyées, au moyen de poulies portées par la structure 1, dans une zone où elles sont proches les unes des autres, parallèles entre elles et verticales. Elles sont alors solidarisées ensemble au moyen d'une poignée 9, qui sera décrite plus loin en référence à la figure 3,sur laquelle s'adapte un contrepoids 21 amovible. Comme on le voit aux figures 1 et 2, le renvoi de la corde 7 est assuré par des poulies 10, 11 et 12, le renvoi de la corde 7' s'effectue par des poulies 13, 14, 15, celui de la corde 7" par des poulies 16, 17 et celui de la corde 7"' par des poulies 18, 19.Four hoist systems are arranged at the four corners of the structure 1, each hoist system comprising a pulley 6, 6 ', 6 ", 6"' carried by the bed 2 in the vicinity of each angle and a rope 7, 7 ', 7 ", 7" 'passing over said pulley and one end of which is fixed at a high point 8, 8', 8 ", 8" 'of the structure 1. The four strings 7, 7', 7 ", 7" ' are returned, by means of pulleys carried by the structure 1, in an area where they are close to each other, mutually parallel and vertical. They are then joined together by means of a handle 9, which will be described later with reference to FIG. 3, on which a removable counterweight 21 fits. As seen in Figures 1 and 2, the return of the rope 7 is provided by pulleys 10, 11 and 12, the return of the rope 7 'is effected by pulleys 13, 14, 15, that of the rope 7 "by pulleys 16, 17 and that of the rope 7" 'by pulleys 18, 19.

Une traction exercée sur la poignée 9 permet d'obtenir des déplacements verticaux identiques des quatre angles du lit 2, avec une démultiplication des déplacements linéaires qui est équivalente à la démultiplication assurée par les systèmes de palans. Avantageusement une telle démultiplication peut être prévue de façon que le déplacement vertical de la poignée 9 soit double du déplacement vertical du lit 2.A traction exerted on the handle 9 makes it possible to obtain identical vertical displacements of the four angles of the bed 2, with a reduction in linear displacements which is equivalent to the reduction provided by the hoist systems. Advantageously, such a reduction can be provided so that the vertical displacement of the handle 9 is double the vertical displacement of the bed 2.

Comme on le voit à la figure 3, la poignée 9 est allongée en forme de glissière, avec une partie inférieure évasée 20. Les extrémités libres des quatre cordes 7, 7', 7", 7"' sont fixées par sertissage à l'extrémité supérieure de la poignée 9. On a représenté en 21 un contrepoids amovible, réalisé en fonte, qui présente un perçage central 22 sur toute sa hauteur et qui est ouvert axialement sur une de ses faces latérales. La largeur du perçage intérieur 22 du contrepoids 21 est légèrement supérieure à celle du corps de la poignée 9, et elle va en se rétrécissant à la partie supérieure du contrepoids. On comprend ainsi que, en position d'utilisation, le contrepoids 21 repose sur la partie inférieure évasée 20 de la poignée 9, alors que le corps de celle-ci est logé à l'intérieur du perçage 22 du contrepoids. Pour retirer le contrepoids, la poignée 9 étant maintenue dans sa position basse, on fait coulisser vers le haut le contrepoids le long du corps de poignée, puis après une rotation d'un quart de tour on dégage le contrepoids du corps de poignée grâce à l'ouverture ménagée sur toute la hauteur de la face latérale du contrepoids. On comprend que la mise en place du contrepoids sur la poignée s'effectuera par l'opération inverse.As can be seen in FIG. 3, the handle 9 is elongated in the form of a slide, with a flared lower part 20. The free ends of the four cords 7, 7 ', 7 ", 7"' are fixed by crimping to the upper end of the handle 9. There is shown at 21 a removable counterweight, made of cast iron, which has a central bore 22 over its entire height and which is open axially on one of its lateral faces. The width of the internal bore 22 of the counterweight 21 is slightly greater than that of the body of the handle 9, and it goes by narrowing at the top of the counterweight. It is thus understood that, in the position of use, the counterweight 21 rests on the flared lower part 20 of the handle 9, while the body of the latter is housed inside the bore 22 of the counterweight. To remove the counterweight, the handle 9 being kept in its low position, the counterweight is slid upwards along the handle body, then after a quarter-turn rotation the counterweight is released from the handle body thanks to the opening provided over the entire height of the lateral face of the counterweight. It is understood that the establishment of the counterweight on the handle will be carried out by the reverse operation.

Avec une démultiplication telle que mentionnée plus haut, selon laquelle la course verticale de la poignée 9 est double de celle du lit 2, on peut ainsi utiliser un contrepoids dont la masse peut être légèrement inférieure à la moitié de la masse du lit 2. Cela est particulièrement avantageux en permettant de réduire le coût de fabrication et de transport du contrepoids, ainsi que l'encombrement de celui-ci.With a reduction as mentioned above, according to which the vertical stroke of the handle 9 is twice that of the bed 2, it is thus possible to use a counterweight whose mass may be slightly less than half the mass of the bed 2. This is particularly advantageous by reducing the cost of manufacturing and transporting the counterweight, as well as the size thereof.

En position basse d'utilisation le lit 2 repose sur des cales, non représentées au dessin, dont la position peut être réglable. Pour faire monter le lit, l'utilisateur tire sur la poignée 9 en n'ayant à exercer qu'un effort très réduit. Les frottements des cordes et des poulies sont tels que le lit tient tout seul en équilibre dans toutes les positions et en particulier en position haute. Une butée haute, non représentée au dessin, limite la course du lit, et en conséquence celle du contrepoids. A l'inverse, pour faire descendre le lit, l'utilisateur soulève le contrepoids sans avoir là encore d'effort à développer.In the low position of use, the bed 2 rests on wedges, not shown in the drawing, the position of which can be adjustable. To raise the bed, the user pulls the handle 9 without having to exert a very reduced force. The friction of the ropes and the pulleys is such that the bed holds itself in balance in all positions and in particular in the high position. A high stop, not shown in the drawing, limits the travel of the bed, and consequently that of the counterweight. Conversely, to lower the bed, the user lifts the counterweight without again having to develop effort.

Comme on l'a représenté à la figure 4, chaque corde 7, 7', 7", 7"' est fixée au poteau 3 correspondant de la structure 1 au' moyen d'un organe coinceur 23 vissé sur le poteau 3 et à travers lequel la corde 7 ne peut coulisser que dans un seul sens (sens de la flèche A de la figure 4). Ainsi, par simple traction sur l'extrémité de chaque corde 7, 7', 7", 7"' passant dans l'organe coinceur correspondant 23 on peut règler l'assiette du lit 2 sans avoir à agir sur les extrémités de ces cordes fixées à la poignée 9.As shown in FIG. 4, each rope 7, 7 ', 7 ", 7"' is fixed to the corresponding post 3 of the structure 1 by means of a clamping member 23 screwed onto the post 3 and to through which the rope 7 can only slide in one direction (direction of arrow A in Figure 4). Thus, by simply pulling on the end of each rope 7, 7 ', 7 ", 7"' passing through the corresponding jamming member 23, the trim of the bed 2 can be adjusted without having to act on the ends of these cords attached to the handle 9.

Enfin on a représenté à la figure 5 une variante selon laquelle le dispositif de commande du déplacement vertical du lit 2, par poignée et contrepoids, est remplacé par un treuil 24, les cordes 7, 7', 7", 7"' s'enroulant simultanément côte à côte sur le tambour unique 25 de ce treuil. Les poulies 12,15, 17 et 19 ne sont alors plus nécessaires. Ainsi, avec le système de palan assurant une démultiplication de moitié, la force de levage à fournir par le treuil sera réduite de moitié.Finally, there is shown in FIG. 5 a variant according to which the device for controlling the vertical movement of the bed 2, by handle and counterweight, is replaced by a winch 24, the ropes 7, 7 ', 7 ", 7"' s' simultaneously winding side by side on the single drum 25 of this winch. The pulleys 12, 15, 17 and 19 are then no longer necessary. Thus, with the hoist system ensuring a reduction in half, the lifting force to be supplied by the winch will be reduced by half.

On comprendra que la description ci-dessus a été fournie à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de l'invention. On comprendra en particulier que, au lieu de quatre cordes de virage agissant aux quatre coins du lit, on pourrait ne prévoir que deux cordes de tirage qui agiraient sur deux coins opposés de celui-ci.It will be understood that the above description has been provided by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the invention. It will be understood in particular that, instead of four turning cords acting at the four corners of the bed, one could only provide two drawing cords which would act on two opposite corners thereof.
