Abstract

The present invention relates to a device for lifting and lowering of stretchers 51 by means of supports sliding on rails which are fixed along a number of vertical walls or a single vertical wall 43. Stretcher supports 3, 4, 5, 6, 7 and 8 slide downwards and upwards on rails 1 and 2 by means of profiles 9 and 10, 11 and 12 of appropriate shape. The stretcher supports are articulated by means of a shaft 17 and a clevis 18, for example, and can be retracted. The slide profiles 9 and 10 on the rails 1 and 2 are extended to the maximum and connect the stretcher supports 3 and 4, 5 and 6, respectively, thereby permitting a straightforward sliding and a stable squaring of the stretcher supports 3, 4, 5 and 6. The stretcher supports 7 and 8 integral with the slide profiles 11 and 12 can slide separately and manually blocked in height by the pin 19 and, for example, an adjustable foot 22. The manoeuvres for sliding the stretcher supports 3, 4, 5 and 6 downwards 24 or upwards 25 are effected with the aid of a single cable 26 and rollers 27, 28, 29 and 30, the said cable being drawn tight or loosened under the load by a winch 33 fixed on the partition wall 43. The devices of the invention advantageously ensure a multiplicity of combinations of lifting, lowering and variable spacing of stretchers with the aid of simple and robust means which are well suited to the management of injured persons.

Description

Supports de brancards à relevage et descente réglables, avec ou sans blessés. Adjustable lift and lower stretcher supports, with or without injuries.

La présente invention concerne un dispositif d'élévation et descente de brancards par coulissement de supports sur des rails fixés le long d'une ou plusieurs parois verticales. The present invention relates to a device for raising and lowering stretchers by sliding supports on rails fixed along one or more vertical walls.

Pour loger des blessés installés sur des brancards, dans une chambre fixe ou dans une cellule mobile, il existe des supports en échelle ou en ratelier sur lesquels peuvent venir s'appuyer, l'un au-dessus de l'autre 2 ou 3 brancards par leurs extrémités, chargés de leur blessé. To accommodate the wounded installed on stretchers, in a fixed room or in a mobile cell, there are ladder or rack supports on which can come to rest, one above the other 2 or 3 stretchers by their extremities, charged with their wounded.

Des systèmes de levage de brancards chargés à partir d'une position initiale basse rendue possible par un coulissement de support coulissant sur un rail fixé sur une paroi, à l'aide de câbles tirés par treuils, existent aussi, mais ils présentent l'inconvénient de devoir manoeuvrer les supports les uns après les autres, ce qui entraine des dispositifs complexes et fragiles. Lifting systems for stretchers loaded from a low initial position made possible by sliding support sliding on a rail fixed to a wall, using cables pulled by winches, also exist, but they have the disadvantage having to maneuver the supports one after the other, which leads to complex and fragile devices.

Aussi la présente invention a-t-elle pour but la mise en oeuvre de moyens simples et robustes, rendant facile la manoeuvre de levage ou d'abaissement de brancards chargés, à partir du coulissement des supports de brancard sur des rails fixés à une ou plusieurs parois. The object of the present invention is therefore the implementation of simple and robust means, making it easy to maneuver the lifting or lowering of loaded stretchers, from the sliding of the stretcher supports on rails fixed to one or more several walls.

Pour assurer une bonne rigidité à la charge et faciliter le coulissement des supports de brancard, ces supports sont reliés ensemble, par deux, au niveau de leur partie coulissante, allongée au maximum. To ensure good rigidity to the load and facilitate the sliding of the stretcher supports, these supports are connected together, in pairs, at their sliding part, elongated to the maximum.

La manoeuvre s'effectue à l'aide d'un treuil à mouvement réversible auto freiné par exemple, pour les brancards reliés, chargés, un système de poulies et de câbles permettant d'entrainer en même temps, les supports maintenant les 2 bras avant et les 2 bras arrière de chaque brancard en élévation ou en abaissement. The operation is carried out using a self-braking reversible winch for example, for connected, loaded stretchers, a system of pulleys and cables making it possible to train at the same time, the supports holding the 2 front arms and the 2 rear arms of each stretcher in raising or lowering.

Si l'on souhaite, modifier l'écartement des brancards l'un par rapport à l'autre, sur leur hauteur de rangement, ou si lton veut simplement réduire le nombre de brancards de 3 à 2 ou à 1 seul, sans être gêné par les supports non utilisés, ces supports, même reliés entre eux au niveau de leur partie coulissante, peuvent se rabattre par le moyen d'articulations appropriées équipées de butées de maintien en position, par exemple le long de la cloison verticale parallèlement aux brancards ou verticalement le long des rails.  If you wish, modify the spacing of the stretchers relative to each other, on their storage height, or if you just want to reduce the number of stretchers from 3 to 2 or to 1 only, without being bothered by the unused supports, these supports, even connected to each other at their sliding part, can be folded down by means of appropriate articulations equipped with stops for holding in position, for example along the vertical partition parallel to the stretchers or vertically along the rails.

En revenant plus particulièrement à la figure l,celle-ci représente des rails 1 et 2 fixés au moins sur une cloison 43. Sur les dits rails coulissent de haut en bas 24, ou de bas en haut 25, des supports de brancards, 3, 4, 5, 6, 7 et 8, au moyen de profilés en C, 9 et 10, 11 et 12, de forme adaptée à l'obtention d'un coulissement facile ; dans le mode de réalisation présentée les ailes 13 et 14 des rails 1 et 2 sont en T. Returning more particularly to FIG. 1, this represents rails 1 and 2 fixed at least on a partition 43. On the said rails slide from top to bottom 24, or from bottom to top 25, stretcher supports, 3 , 4, 5, 6, 7 and 8, by means of C sections, 9 and 10, 11 and 12, of a shape suitable for obtaining an easy sliding; in the embodiment presented, the wings 13 and 14 of the rails 1 and 2 are made of T.

Les rails 1 et 2 peuvent être fixés à la cloison 43, à 45c de leur position longitudinale initiale suivant détail 1'. The rails 1 and 2 can be fixed to the partition 43, at 45c from their initial longitudinal position according to detail 1 '.

Les dits supports de brancards sont manoeuvrés par coulissement vers le bas ou vers le haut, chargés de blessés ou non. Said stretcher supports are maneuvered by sliding down or up, loaded with injured or not.

Un moyen de fixation des bras d'un brancard est représenté à titre d'exemple en 15 et 16 sur le brancard 4. A means of fixing the arms of a stretcher is shown by way of example at 15 and 16 on the stretcher 4.

Les supports de brancards 3, 4,ou 3' et 4', 5, 6, 7 et 8 sont articulés par exemple au moyen d'un axe 17 et d'une chape 18 ou 18' et s'escamote. The stretcher supports 3, 4, or 3 'and 4', 5, 6, 7 and 8 are articulated for example by means of a pin 17 and a yoke 18 or 18 'and retracts.

Le mode de réalisation des dispositifs de l'invention fait ressortir les avantages qui suivent une fois les ou le brancards 25 chargés de blessés. The embodiment of the devices of the invention highlights the advantages which follow once the or stretchers 25 are loaded with injuries.

Les moyens de coulissement sont allongés au maximum dans le dispositif décrit, du fait que les profilés 9 et 10 relient les supports de brancards 3 et 14, et, 5 et 6 et permettent ainsi un coulissement facile de ces pièces le long des rails 7 et 2 et un équerrage solide des dits supports sur les dits rails les supports de brancards 7 et 8 équipés des profils de coulissement 11 et 12, par exemple, peuvent coulisser-séparément et manuellement avant la mise en place d'un blessé, le bloquage en hauteur et l'equerrage se faisant par exemple par une goupille 19 pénètrant dans un trou percé dans le profil 12 et l'un des trous 20 ou 21 percés dans le rail 2, et par un pied 22 réglable en hauteur repliable sous le support brancard comme le montre la position 23. The sliding means are elongated to the maximum in the device described, because the sections 9 and 10 connect the stretcher supports 3 and 14, and, 5 and 6 and thus allow easy sliding of these parts along the rails 7 and 2 and a solid squaring of said supports on said rails the stretcher supports 7 and 8 equipped with sliding profiles 11 and 12, for example, can slide-separately and manually before the placement of an injured person, the blocking in height and squaring being done for example by a pin 19 entering a hole drilled in the profile 12 and one of the holes 20 or 21 drilled in the rail 2, and by a foot 22 adjustable in height foldable under the stretcher support as shown in position 23.

Les manoeuvres de coulissement sur les rails 7 et 2 des profilés 9 et 10 et des supports de brancards 3, 4, 5 et 6 en descente vers le bas 24 et relevage vers le haut 25, s'effectuent au moyen d'un seul câble 26 et de quatre poulies 27, 28, 29 et 30 au moins, le dit câble étant attaché par un moyen quelconque aux points 31 et 32 des profilés 9 et 10 ; le dit câble est tiré ou relâché, sous la charge, dans un sens ou dans l'autre, par un treuil 33, à mouvement réversible auto-freiné par exemple, fixé sur la cloison 43. The sliding maneuvers on the rails 7 and 2 of the sections 9 and 10 and of the stretcher supports 3, 4, 5 and 6 when lowering down 24 and lifting up 25, are carried out by means of a single cable 26 and four pulleys 27, 28, 29 and 30 at least, the said cable being attached by any means to points 31 and 32 of the sections 9 and 10; the said cable is pulled or released, under the load, in one direction or the other, by a winch 33, with reversible self-braking movement for example, fixed on the partition 43.

Les figures 2, 3 et 4 présentent un exemple de dispositif de liaiscn d'un support de brancard 6 sur un profil en C, 9, qui coulisse sur un rail 2. Cette liaison peut-être réalisée au moyen de la chape 18 liée par soudure, ou autre moyen, au profil 9, le support brancard 6 étant articulé au profilé 9 coulissant sur les ailes 13 et 14 du rail 2 autour d'un axe 17 traversant la chape 18 et le support 6. Le rail 2 pourrait être représenté, également dans,
une position se situant à 452 de celle des figures 3, 4, 5 et 6. Figures 2, 3 and 4 show an example of a liaiscn device for a stretcher support 6 on a C profile, 9, which slides on a rail 2. This connection can be achieved by means of the yoke 18 linked by welding, or other means, to the profile 9, the stretcher support 6 being articulated to the profile 9 sliding on the wings 13 and 14 of the rail 2 around an axis 17 passing through the yoke 18 and the support 6. The rail 2 could be represented , also in,
a position located 452 from that of FIGS. 3, 4, 5 and 6.

Un moyen de blocage, figure 2 et 3, du support de brancard 6 en position perpendiculaire à la cloison 43, et figure 4 en position parallèle à la cloison 43, est içi constitué de deux plaques renforts 35 et 36 solidaires du support 6, qui viennent se caler en parallèle, sur le même plan figures 2 et 3, ou suivant la position de la figure 4, contre des butées 37 et 38 fixées sur la chape 18, après que le support 6 ait été levé le long de l'axe 17 et redescendu, sous la pression du ressort 34, en appui sur la base 46 de la chape 18, pour être maintenu en face et parallèlement aux butées 37 et 38 à l'aide du ressort 34. A locking means, FIG. 2 and 3, of the stretcher support 6 in position perpendicular to the partition 43, and FIG. 4 in position parallel to the partition 43, is here constituted by two reinforcing plates 35 and 36 integral with the support 6, which are wedged in parallel, on the same plane Figures 2 and 3, or according to the position of Figure 4, against stops 37 and 38 fixed on the yoke 18, after the support 6 has been lifted along the axis 17 and lowered, under the pressure of the spring 34, bearing on the base 46 of the yoke 18, in order to be held opposite and parallel to the stops 37 and 38 using the spring 34.

La figure 5 représente un autre exemple de moyen de coulissement d'un support de brancard 42 ; le dit brancard, d'une longueur de plus de 450 mm, est solidaire d'une pièce 40 qui peut être remplacée, figure 6, par des galets 47 reliés par des axes 48 sur une pièce 49 ; le rail 39 est en forme de C.  FIG. 5 shows another example of a means for sliding a stretcher support 42; said stretcher, with a length of more than 450 mm, is integral with a part 40 which can be replaced, FIG. 6, by rollers 47 connected by pins 48 on a part 49; the rail 39 is C-shaped.

La figure 7 représente un dispositif d'escamotage des supports de brancards 45 par rabattement sur le rail 1, au moyen d'une chape 5G fixée sur le profilé de coulissement 9, mais qui pourrait être également solidaire de la pièce 40 ou de la pièce 49, et d'un axe 44, les pièces 40 et 49 étant représentées sur les figures 5 et 6. FIG. 7 represents a device for retracting the stretcher supports 45 by folding down on the rail 1, by means of a yoke 5G fixed on the sliding profile 9, but which could also be integral with the part 40 or with the part 49, and an axis 44, the parts 40 and 49 being shown in FIGS. 5 and 6.

L'ensemble des dispositifs de l'invention présentée assure une multitude de comb naisons de levage et de descentes de 1, 2 ou de 3 brancards ainsi qu'une multitude de variantes d'espacements entre ces 3 brancards, bien adaptées au service des blessés, à l'aide de moyens simples et robustes.  All of the devices of the invention presented ensure a multitude of combinations of lifting and lowering of 1, 2 or 3 stretchers as well as a multitude of variants of spacings between these 3 stretchers, well suited to serving the injured , using simple and robust means.
