Description

Ce modèke d'utilité concerne en général les lits avec un châssis à éléments articulés et complè­tement repliables pour en réduire au maximum l'en­combrement quand il est nécessaire et plus en parti­culier un dispositif pour le blocage des éléments d'un tel châssis en position d'utilisation.This utility model generally relates to beds with a frame with articulated elements and completely foldable to reduce the overall size when necessary and more particularly a device for locking the elements of such a frame in position d 'use.

On connaît déjà un lit soi-disant à repliement total ayant un châssis pliant qui comprend: un étrier central de fond, quatre tiges articulées à cet étrier et s'étendant à deux à deux en directions opposées selon les diagonales d'un rectangle qui composent le fond du lit; quatre montants d'angle articulés, inférieurement, aux tiges susdites et reliés, supérieurement, à deux à deux par des tra­verses dédoublées et repliables à moitié, et de moyens pour bloquer ces travers es en position hori­zontale pour mettre le lit en position d'utilisation et pour les débloquer quand il faut le replier.There is already known a so-called fully folding bed having a folding frame which comprises: a central bottom bracket, four rods articulated to this bracket and extending in pairs in opposite directions along the diagonals of a rectangle which make up the bottom of the bed; four corner posts articulated, lower, to the above-mentioned rods and connected, superiorly, in pairs by double sleepers and half foldable, and means for locking these sleepers are in a horizontal position to put the bed in the use position and to unlock them when it is necessary to fold it.

Le but de cette invention c'est de proposer un dispositif de simple exécution et dont le fonction­nement est assuré qui permet de bloquer automati­quement chaque traverse du châssis d'un tel lit en position horizontale et de la débloquer pour son repliement seulement en agissant volontairement sur un élément à poussoir de décrochage.The purpose of this invention is to provide a simple execution device and whose operation is ensured which allows to automatically block each cross member of the frame of such a bed in a horizontal position and to unlock it for its folding only by acting voluntarily on a release button element.

Dans ce but les extrémités contigues des deux éléments en forme de tige constituant chaque tra­verse sont aplatis et articulés sur une boîte cen­trale de raccordement et dans cette boîte est mon­tée, en guise de poussoir à ressort, une came ca­pable de bloquer les extrémités des éléments susdits quand ils sont en position horizontale pour en em­pêcher le repliement et de les débloquer à commande pour permettre le repliement des traverses et du châssis du lit.For this purpose the contiguous ends of the two rod-shaped elements constituting each crosspiece are flattened and articulated on a central connection box and in this box is mounted, as a spring plunger, a cam capable of blocking the ends of the above elements when they are in a horizontal position to prevent folding and to unlock them on command to allow folding of the sleepers and the bed frame.

Le dessin ci-joint montre un exemple de réali­sation du dispositif en question appliqué à un petit lit pliant. Dans ce dessin:

  • la Fig. 1 montre une vue perspective d'un lit d'en­fant;
  • la Fig. 2 montre le dispositif de blocage ouvert, en position active et, par lignes en traits, en position de décrochage; et
  • la Fig. 3 montre une section obtenue selon les flêches III-III en Fig. 2.
The attached drawing shows an embodiment of the device in question applied to a small folding bed. In this drawing:
  • Fig. 1 shows a perspective view of a child's bed;
  • Fig. 2 shows the blocking device open, in the active position and, by dashed lines, in the off position; and
  • Fig. 3 shows a section obtained according to arrows III-III in FIG. 2.

Le lit d'enfant auquel on applique le dispo­sitif ici proposé comprend un châssis 10 ayant un étrier central de fond 11 auquel les extrémités de quatre tiges 12 sont articulés, s'étendant à deux à deux en directions opposées selon les diagonales d'un rectangle pour former un plan de fond pour l'appui d'un porte-matelas. Les extrémités des tiges susdites éloignées de l'étrier central sont articu­lées à la partie inférieure de quatre montants cor­respondants 13 qui, supérieurement, sont connectés et articulés à deux à deux avec des traverses 14, dont chacune est formée par deux éléments en forme de barre 15 dressés l'un vers l'autre à partir des montants. Sur le châssis, pour compléter le lit, il y a un enceinte 16 en tissue et/ou filet et en tout cas flexible.The crib to which the device proposed here is applied comprises a frame 10 having a central bottom stirrup 11 to which the ends of four rods 12 are articulated, extending in pairs in opposite directions along the diagonals of a rectangle to form a bottom plane for the support of a mattress holder. The ends of the aforementioned rods remote from the central stirrup are articulated at the lower part of four corresponding uprights 13 which, superiorly, are connected and articulated in pairs with crosspieces 14, each of which is formed by two bar-shaped elements 15 drawn towards each other from the uprights. On the frame, to complete the bed, there is an enclosure 16 made of fabric and / or net and in any case flexible.

Les extrémités contiguës 15′ des deux éléments 15 de chaque traverse 14 sont aplaties et articu­ lées, en 17, à une boîte centrale de raccordement 18, dans laquelle est montée, en guise de poussoir, une came de blocage 19, sollicitée par un ressort 20 et déplaçable transversalement à la boîte, c'est-à-­dire orthogonalement à l'extrémité 15′ des éléments 15.The adjoining ends 15 ′ of the two elements 15 of each cross member 14 are flattened and articulated lées, in 17, to a central connection box 18, in which is mounted, as a pusher, a locking cam 19, biased by a spring 20 and movable transversely to the box, that is to say orthogonally to the 15 ′ end of the elements 15.

Le ressort 20 tend à normalement maintenir la came-poussoir 19 déplacée vers l'extérieur du corps à boîte 18 dans une position dans laquelle un lobe 19′ de la came se trouve dans le même plan que les extrémités 15′ des éléments 15 et en condition d'in­tercepter automatiquement les extrémités elles mêmes quand elles s'alignent l'une à l'autre.The spring 20 tends to normally keep the pusher cam 19 displaced towards the outside of the box body 18 in a position in which a lobe 19 ′ of the cam is in the same plane as the ends 15 ′ of the elements 15 and in condition to automatically intercept the ends themselves when they align with each other.

Pratiquement, quand les éléments 15 sont ho­rizontalement et réciproquement alignés, leurs ex­trémités aplaties 15′ s'appuient automatiquement sur le lobe 19′ de la came 19. De cette façon les élé­ments 15 sont bien bloqués sans aucune possibilité de rotation, en empêchant le repliement des traver­ses et assurant en même temps l'arrêt et la stabi­lité du châssis en position étendue pour l'utili­sation du lit. Et ça jusqu'à ce qu'on agit volon­tairement sur la came-poussoir 19 pour la pousser en opposition au ressort 20 et éloigner ainsi le lobe 19′ de la came 19 de l'extrémité 15′ des éléments 15. Seulement à ce moment-là ces éléments seront débloqués et on pourra les replier pour le replie­ment complet du châssis tout entier. De l'autre part, la came de blocage 19 se porte en position d'intervention automatique immédiate grâce au res­sort 20 pour bloquer de nouveau les éléments 15 susdits aussitôt qu'ils seront portés en position horizontale d'alignement réciproque.In practice, when the elements 15 are horizontally and reciprocally aligned, their flattened ends 15 ′ automatically rest on the lobe 19 ′ of the cam 19. In this way the elements 15 are well locked without any possibility of rotation, preventing folding back sleepers and at the same time ensuring the stopping and the stability of the frame in the extended position for the use of the bed. And this until we act voluntarily on the cam-pusher 19 to push it in opposition to the spring 20 and thus move the lobe 19 ′ of the cam 19 from the end 15 ′ of the elements 15. Only then will these elements be released and can be folded down for the complete folding of the entire chassis. On the other hand, the locking cam 19 goes to the position of immediate automatic intervention thanks to the spring 20 to re-lock the above-mentioned elements 15 as soon as they are brought to the horizontal position of reciprocal alignment.
