Description

SYSTENE DE COMMANDE POUR BRANCARD
D'AMBULANCE A BEQUILLES REPLIABLES
La présente invention concerne un système de commande pour brancard d'ambulance à béquilles repliables.
CONTROL SYSTEM FOR STRETCHER
FOLDING STANDS AMBULANCE
The present invention relates to a control system for an ambulance stretcher with folding crutches.

Un brancard d'ambulance de ce type comprend un brancard proprement dit pouvant être placé amoviblement sur un chariot muni de béquilles pivotantes, ces béquilles pouvant être repliées pour l'introduction de l'ensemble dans une ambulance et dépliées pour le transport du patient dans l'hôpital. An ambulance stretcher of this type comprises a stretcher proper which can be removably placed on a trolley provided with pivoting crutches, these crutches can be folded up for the introduction of the assembly into an ambulance and unfolded for transporting the patient in the 'hospital.

Le système d'actionnement du déverrouillage des béquilles et du repliage de celles-ci est commandé, sur tous les brancards existants, par des manettes disposées soit sur le côté du chariot, soit à l'arrière de celui-ci, à proximité des poignées de portage du brancard. The actuation system for unlocking the crutches and folding them up is controlled, on all existing stretchers, by levers arranged either on the side of the trolley or at the back of the trolley, near the handles carrying the stretcher.

Dans un cas comme dans l'autre, les manettes sont fixes et saillantes, et peuvent être actionnées accidentellement, ce qui peut entraîner le renversement du brancard, avec les risques que cela implique pour le patient. In either case, the handles are fixed and protruding, and can be actuated accidentally, which can cause the stretcher to overturn, with the risks that this implies for the patient.

La présente invention vise à remédier à cet inconvénient, sans limiter pour autant l'accessibilité des manettes et au moyen d'un dispositif très simple, fiable et peu coûteux à réaliser. The present invention aims to remedy this drawback, without however limiting the accessibility of the joysticks and by means of a very simple, reliable and inexpensive device to produce.

A cette fin, le système de commande qu'elle concerne comprend, d'une part, une barre de commande du mécanisme de repliage des béquilles, située à proximité des poignées de portage du brancard et disposée transversalement par rapport aux longerons de celui-ci et, d'autre part, au moins une manette permettant de faire pivoter cette barre autour de son axe pour commander ledit mécanisme, fixée à la barre de manière à pouvoir être déplaçable entre une position active, dans laquelle elle est perpendiculaire à l'axe de la barre et constitue un levier permettant le pivotement de celle-ci, et une position escamotée, dans laquelle elle est parallèle audit axe et ne permet pas de faire pivoter ladite barre. To this end, the control system to which it relates comprises, on the one hand, a control bar for the crutch folding mechanism, located near the carrying handles of the stretcher and arranged transversely relative to the side members thereof. and, on the other hand, at least one lever making it possible to pivot this bar around its axis to control said mechanism, fixed to the bar so as to be able to be moved between an active position, in which it is perpendicular to the axis of the bar and constitutes a lever allowing the pivoting thereof, and a retracted position, in which it is parallel to said axis and does not allow said bar to pivot.

Ainsi, la manette peut être escamotée en dehors de son utilisation, ce qui permet d'éliminer tout risque d'actionnement intempestif du repliage des béquilles. Le système selon l'invention est simple, fiable et peu onéreux à réaliser. Thus, the lever can be retracted outside of its use, which eliminates any risk of inadvertent actuation of the folding of the crutches. The system according to the invention is simple, reliable and inexpensive to produce.

Selon une forme de réalisation simple de l'invention, la barre comprend, fixées à elle, deux pattes parallèles percées de deux trous coaxiaux, constituant une chape de réception de l'extrémité correspondante de la manette, qui comprend un trou, cette extrémité pouvant être engagée dans ladite chape avec venue des trous précités coaxialement les uns aux autres pour l'introduction au travers d'eux d'un boulon formant axe de pivotement. According to a simple embodiment of the invention, the bar comprises, fixed to it, two parallel legs pierced with two coaxial holes, constituting a yoke for receiving the corresponding end of the lever, which comprises a hole, this end being able to be engaged in said yoke with the abovementioned holes coming coaxially to each other for the introduction through them of a bolt forming a pivot axis.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du système qu'elle concerne. In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the system which it concerns.

La figure 1 en est une vue de côté ; et
la figure 2 en est une vue de dessus.
Figure 1 is a side view; and
Figure 2 is a top view.

Les figures représentent, sous différents angles, un système de commande 1 du mécanisme de repliage des béquilles d'un brancard. The figures represent, from different angles, a control system 1 for the folding mechanism of the struts of a stretcher.

Ce système comprend une barre de commande 2 et une manette 3 permettant de faire pivoter cette barre 2 autour de son axe afin d'actionner en translation, par l'intermédiaire d'une patte radiale 4, la tringle 5 reliée au mécanisme de commande des béquilles. This system comprises a control bar 2 and a lever 3 making it possible to pivot this bar 2 about its axis in order to actuate in translation, by means of a radial tab 4, the rod 5 connected to the mechanism for controlling the crutches.

La barre 2 est portée par des paliers 6 fixés aux longerons 7 du brancard, à proximité des poignées de portage 8, et est disposée transversalement par rapport aux longerons 7.  The bar 2 is carried by bearings 6 fixed to the side members 7 of the stretcher, near the carrying handles 8, and is arranged transversely relative to the side members 7.

Elle comprend, fixées perpendiculairement à elle, deux pattes 9 parallèles percées de deux trous coaxiaux, constituant une chape. It comprises, fixed perpendicular to it, two parallel legs 9 pierced with two coaxial holes, constituting a yoke.

L'extrémité de la manette 3 ne comprenant pas la poignée 10 présente un trou, cette extrémité pouvant être engagée dans ladite chape avec venue des trous précités coaxialement les uns aux autres pour l'introduction au travers d'eux d'un boulon 11 formant axe de pivotement. The end of the handle 3 not including the handle 10 has a hole, this end can be engaged in said yoke with the abovementioned holes coming coaxially to each other for the introduction through them of a bolt 11 forming pivot axis.

Ainsi que cela apparaît sur les figures, grâce au système de commande selon l'invention, la manette 3 est déplaçable entre une position active, représentée en traits pleins sur les figures, dans laquelle elle est perpendiculaire à l'axe de la barre 2 et constitue un levier permettant le pivotement de celle-ci, et une position escamotée, représentée en traits mixtes sur la figure 2, dans laquelle elle est parallèle audit axe et ne permet pas de faire pivoter ladite barre 2. As shown in the figures, thanks to the control system according to the invention, the lever 3 is movable between an active position, shown in solid lines in the figures, in which it is perpendicular to the axis of the bar 2 and constitutes a lever allowing the latter to pivot, and a retracted position, shown in broken lines in FIG. 2, in which it is parallel to said axis and does not allow said bar 2 to be pivoted.

Ainsi, la manette peut être escamotée en dehors de son utilisation, ce qui permet d'éliminer tout risque d'actionnement intempestif du repliage des béquilles, avec les conséquences graves que cela peut impliquer pour le patient. Thus, the lever can be retracted outside of its use, which eliminates any risk of untimely actuation of the folding of the crutches, with the serious consequences that this may imply for the patient.

Le système selon l'invention est à la fois simple, fiable et peu onéreux à réaliser.  The system according to the invention is both simple, reliable and inexpensive to produce.
