Abstract

Mechanism for tilting a bed in a sagittal plane from the horizontal position to the vertical position and vice versa. The invention relates to a mechanism capable of tilting a bed in a sagittal plane in order to assist a person who is standing up to lie down and vice versa. It consists of a fixed part (F) and a movable bed-supporting part (M) hinged together by two pairs of links (C). The bed is moved by a geared motor acting on the shafts R2 and R4. The mechanism according to the invention is particularly intended for persons who have physical problems in lying down or getting up.

Description

LIT A BASCULEMENT SAGITTAL
La présente invention concerne un dispositif permettant le basculement d'un lit, par un motuer, de la position verticale à la positior horizontale et vice versa, dans le plan sagittal.SAGITTAL TILT BED
The present invention relates to a device allowing the tilting of a bed, by a motuer, from the vertical position to the horizontal positior and vice versa, in the sagittal plane.

les lits @asculants généralement existants ont un axe de basculement fixe et une position horizontale relativement plus haute qu'un lit normal. generally existing tilting beds have a fixed tilt axis and a relatively higher horizontal position than a normal bed.

Le dispositif selon l'invention perinet de faire passer un lit de la position verticale a la position horizontale et vice versa de telle manière qu'en position horizontale le lit soit à environ 65 cm du sol. The device according to the invention makes it possible to pass a bed from the vertical position to the horizontal position and vice versa so that in a horizontal position the bed is approximately 65 cm from the ground.

Pendant Le mouvement plaçant le lit en position horizontale, il y a abaissement du centre de gravité.During the movement placing the bed in a horizontal position, there is a lowering of the center of gravity.

A cette fin, quatre bielles parallèles deux à deux, articulées sur un chassis fixe et sous le lit, imposent de déplacement de celui-ci. To this end, four parallel connecting rods two by two, articulated on a fixed frame and under the bed, require movement of the latter.

Un moto-réducteur agissant sur les axes des bielles se trouvant sous le lit permet la mobilisation de celui.-c:i. A gear motor acting on the axes of the connecting rods located under the bed allows the mobilization of the latter: i.

Ea planche l comporte trois figures
Le dispositif est composé de quatre constituants : - un chassis fixe (F) destiné à fournir la stabilité de l'ensemble et les points fixes d'articulation des bielles ; - deux paires de bielles (C) articulées sur le chassis fixe et le support du lit mobile (M) contenant le moto-réducteur ; - le support de lit contenant le moto--réducteur (M) ; - le lit (L) comportant un marche pieds (H) ;
La figure i représente une vue du côté droit du lit en position horizontale. Les bielles sont indiquées par la lettre (C). L'emplacement du moto-réducteur, support de lit, par la lettre (M).This board has three figures
The device is made up of four components: - a fixed frame (F) intended to provide the stability of the assembly and the fixed points of articulation of the connecting rods; - two pairs of connecting rods (C) articulated on the fixed frame and the support of the moving bed (M) containing the gear motor; - the bed support containing the gear motor (M); - the bed (L) comprising a step (H);
Figure i shows a view of the right side of the bed in a horizontal position. The connecting rods are indicated by the letter (C). The location of the gear motor, bed support, by the letter (M).

La figure 2 représente une vue depuis la tête du lit. Figure 2 shows a view from the head of the bed.

Le lit peut recevoir des accessoires tels que poignées ou protections (P)
La planche 2 représente l'ensemble support de lit et la force motrice choisie ici par un groupe, moto-réducteur (MR) avec les chaînes permettant la mobilisation l'un par rapport a l'autre des axes des bielles Les lettres A,B,C, désignent les trois chaînes à rouleaux utilisées.The bed can receive accessories such as handles or protections (P)
Plate 2 represents the bed support assembly and the driving force chosen here by a group, geared motor (MR) with the chains allowing the mobilization, relative to each other, of the axes of the connecting rods The letters A, B , C, denote the three roller chains used.

Les deux planches décrivent un exemple de réalisation dont les dimensions, la force motrice, la structure et les matériaux utilisés sont choisis de manière à supporter et assurer les déplacements d'une masse hurnaine
Le principe du dispositif est: essentiellement dans l'agencement des deux paires de bielles entre le chassis fixe et le support de lit mobile.The two plates describe an exemplary embodiment, the dimensions, the driving force, the structure and the materials used being chosen so as to support and ensure the displacements of a human mass
The principle of the device is: essentially in the arrangement of the two pairs of connecting rods between the fixed frame and the movable bed support.

Les dimensions et les formes sont données à titre d'exemple de réalisation. Dimensions and shapes are given as an example of an embodiment.

Le dispositif selon l'invention est destiné à la fabrication de matériel pour les personnes handicapées. The device according to the invention is intended for the manufacture of equipment for the disabled.
