Abstract

The medical examination table has a single motor drive for tilting and laying the table flat, which has steps (H). The small longitudinal displacement of the section connected with the steps when the examination table passes the vertical position to the horizontal position through a n articulation linkage (C). A pair of the links (C1-C2) is hinged vertically on two further links (C5-C6) themselves articulated on the fixed frame (F). A link (C4) is articulated at two fixed symmetrical points on the frame (F) and at two symmetrical points on the support.

Description

LIT OU TABLE D'EXAMENS A BASCULEMENT SAGITTAL
ET LEVANT HORIZONTALEMENT
La présente invention concerne un dispositif permettant le basculement d'un lit ou d'une table d'examens de la position verticale à la position horizontale et vice versa, dans le plan sagittal, et de le lever horizontalement avec un seul moto-réducteur.SAGITTAL TIPPING BED OR EXAM TABLE
AND RISING HORIZONTALLY
The present invention relates to a device allowing the tilting of a bed or an examination table from the vertical position to the horizontal position and vice versa, in the sagittal plane, and to raise it horizontally with a single gear motor.

Les lits basculants ou les tables d'examens généralement existants ont un axe de basculement fixe et une partie fixe dont l'encombrement au sol dépasse la projection de la partie mobile en position horizontale. Le basculement et le levage nécessitent généralement deux moteurs. The generally existing tilting beds or examination tables have a fixed tilting axis and a fixed part whose bulk on the ground exceeds the projection of the mobile part in a horizontal position. Tipping and lifting generally require two motors.

Le dispositif selon l'invention permet de faire passer un lit ou une table d'examens de la position verticale à la position horizontale et vice versa, ainsi que de lever horizontalement le lit ou la table d'examens de telle manière qu'aucune pièce mécanique ne se trouve au-dessus et (ou) en-dehors du lit ou de la table d'examens, évitant ainsi tout risque d'interposition d'un membre. The device according to the invention makes it possible to move a bed or an examination table from the vertical position to the horizontal position and vice versa, as well as to raise the bed or the examination table horizontally so that no part mechanical is not above and / or outside the bed or the examination table, thus avoiding any risk of interposition of a member.

A cette fin, cinq bielles (dont quatre parallèles deux à deux), articulées sur un châssis fixe imposent le déplacement de celui-ci. To this end, five connecting rods (including four parallel two by two), articulated on a fixed frame require the displacement thereof.

Un moto-réducteur agissant entre l'axe R1 et R2 permet la mobilisation du plan support (M). A gear motor acting between the axis R1 and R2 allows the mobilization of the support plane (M).

La planche 1 comporte trois figures. Plate 1 has three figures.

Le dispositif est composé de cinq constituants
- un châssis fixe (F) destiné à fournir la stabilité de l'ensemble et les points fixes d'articulation des bielles
- une paire de bielles (C5-C6) articulées sur le châssis fixe en R11-
R12 avec une paire (C1-C2) articulée en R3-R4, elle-même articulée avec le plan support (M) en R5-R6 [sur la figure 2, les axes R3-R5 et R4-R6, sont représentés confondus, compte-tenu de leur quasi superposition entraînée par la position représentée des bielles C1 et C2]. C1 et C2 comportent un verrou en rapport avec les tenons T1 et T2 solidaires du châssis (F)
- une bielle (C4) articulée au châssis fixe en R7-R8 et le plan support (M) en R9-R10;
- le support du lit ou table d'examens (M)
- le lit ou la table d'examens comportant un marche pied (H).The device is made up of five components
- a fixed frame (F) intended to provide the stability of the assembly and the fixed points of articulation of the connecting rods
- a pair of connecting rods (C5-C6) articulated on the fixed chassis in R11-
R12 with a pair (C1-C2) articulated in R3-R4, itself articulated with the support plane (M) in R5-R6 [in FIG. 2, the axes R3-R5 and R4-R6, are shown combined, taking into account their quasi superposition brought about by the position shown of the connecting rods C1 and C2]. C1 and C2 have a lock in connection with the pins T1 and T2 secured to the chassis (F)
- a connecting rod (C4) articulated to the fixed frame in R7-R8 and the support plane (M) in R9-R10;
- the support of the bed or examination table (M)
- the examination bed or table with a step (H).

La figure 1 représente une vue du côté droit en position quasi verticale. Les bielles sont indiquées par la lettre (C). Le moto-réducteur est placé entre les axes R1 et R2. Figure 1 shows a view of the right side in an almost vertical position. The connecting rods are indicated by the letter (C). The gear motor is placed between the axes R1 and R2.

La figure 2 représente une vue de dessus. Figure 2 shows a top view.

La figure 3 représente le détail d'un verrou. Figure 3 shows the detail of a lock.

Le lit ou la table d'examens peut recevoir des accessoires tels que poignées ou protections. The examination bed or table can receive accessories such as handles or protections.

La planche 2 représente une variante simplifiée d'un lit ou d'une table d'examens sans la possibilité de levage horizontale et deux figures. Plate 2 represents a simplified variant of a bed or an examination table without the possibility of horizontal lifting and two figures.

A cette fin, quatre bielles parallèles deux à deux, articulées sur un châssis fixe imposent le déplacement. To this end, four parallel connecting rods two by two, articulated on a fixed frame require displacement.

Un moto-réducteur agissant entre l'axe (R2) solidaires des bielles (C3 - C4) et l'axe (Ri) permet la mobilisation du plan support (M). A gear motor acting between the axis (R2) integral with the connecting rods (C3 - C4) and the axis (Ri) allows the mobilization of the support plane (M).

Le dispositif est composé de quatre constituants
- un châssis 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 châssis fixe et le support du lit mobile (M);
- le support du lit ou table d'examens (M)
- le lit ou la table d'examens comportant un marche pied (H). 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);
- the support of the bed or examination table (M)
- the examination bed or table with a step (H).

La figure 2 représente une vue de dessus. Figure 2 shows a top view.

Les deux planches décrivent deux exemples de réalisaton 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 humaine. The two plates describe two examples of realization whose dimensions, motive force, structure and materials used are chosen so as to support and ensure the displacements of a human mass.

Le principe du dispositif est essentiellement dans l'agencement des bielles entre le châssis fixe, le support de lit mobile, et entre elles, ainsi que dans les verrous. The principle of the device is essentially in the arrangement of the connecting rods between the fixed frame, the mobile bed support, and between them, as well as in the latches.

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.
