Abstract
Description
La présente invention concerne les appareils du type "descendeur" permettant, en cas d'incendie, l'évacuation d'immeubles par l'extérieur, le long d'une corde ou d'un câble. The present invention relates to devices of the "descender" type allowing, in the event of a fire, the evacuation of buildings from the outside, along a rope or cable.
Les dispositifs connus de ce genre peuvent se classer en deux ca tégories selon qu'ils sont accrochés à poste fixe sur l'immeuble ou drec- tement assujettis au baudrier de l'utilisateur. Known devices of this kind can be classified into two categories depending on whether they are attached to a fixed post on the building or are strictly subject to the user's harness.
Dans le premier cas, les appareils sont habituellement réglés à la fabrication pour une certaine vitesse de descente, de l'ordre de deux mètres par seconde. Cette vitesse, que la réglementation considère satisfaisante, peut se révéler excessive pour l'évacuation de personnes handicapées, blessées, âgées ou évanouies, dès lors qu'elles sont dans l'incapacité d'amortir le choc à l'arrivée au sol et d'éviter correctement certains obstacles tels que les balcons successifs. In the first case, the devices are usually adjusted during manufacture for a certain descent speed, of the order of two meters per second. This speed, which the regulations consider satisfactory, may prove excessive for the evacuation of disabled, injured, elderly or fainted people, since they are unable to absorb the shock on arrival on the ground and d '' correctly avoid certain obstacles such as successive balconies.
Dans le second cas, c'est l'utilisateur qui règle sa propre descente en libérant au fur et à mesure la corde qu'il tient d'une main ou des deux mains selon le type d'appareil. Une telle manoeuvre qui suppose une grande maiise, et de préférence un certain entralnement, n'est pas à la portée de tous. Le frottement de la corde peut, en outre, occasionner des brûlures des mains. In the second case, it is the user who regulates his own descent by releasing progressively the rope which he holds with one hand or with both hands depending on the type of device. Such a maneuver which requires great skill, and preferably some training, is not within everyone's reach. Friction of the rope can also cause hand burns.
Le dispositif selon l'invention permet d'éviter tous ces inconvénients. A tout instant la vitesse de descente peut être réduite ou annulée à volonté, aussi bien pour le passage des obstacles que pour l'arrivée au sol ; sans que l'utilisateur ait à tenir la corde. En outre, le dispositif peut être utilisé indifféremment à poste fixe en vue de l'évacuation successive de plusieurs personnes, moyennant l'intervention d'un tiers, ou as sujette directement au baudrier de l'utilisateur. The device according to the invention makes it possible to avoid all of these drawbacks. At any time the descent speed can be reduced or canceled at will, both for the passage of obstacles and for the arrival on the ground; without the user having to hold the rope. In addition, the device can be used interchangeably at a fixed position for the successive evacuation of several people, with the intervention of a third party, or as subject directly to the user's harness.
Le dispositif est caractérisé par le fait qu'il comporte un moyen destiné à freiner la descente et à arreter automatiquement cette dernière en cas de besoin ou en cas de défaillance de l'utilisateur. The device is characterized by the fact that it includes a means intended to brake the descent and to stop it automatically if necessary or in the event of user failure.
Ce moyen est la combinaison d'un couloir dans lequel est engagée la corde de descente, et d'une pièce articulée faisant office de frein ladite pièce étant prolongée par une poignée. En position fermée, une butée limite automatiquement l'angle de rotation de la pièce articulée. La manille ou le mousqueton destiné à la fixation de l'appareil au balcon de l'immeuble ou au baudrier est solidaire de la pièce articulée. This means is the combination of a corridor in which the descent rope is engaged, and an articulated piece acting as a brake, said piece being extended by a handle. In the closed position, a stop automatically limits the angle of rotation of the articulated part. The shackle or carabiner intended for fixing the device to the building balcony or to the harness is secured to the articulated part.
Dans le dispositif'selon l'invention, la corde de descente glisse en développant des forces de frottement, sur des pièces fixes qui délimitent un couloir. De plus, la corde est comprimée entre l'une des pièces fixes et la pièce articulée sur laquelle s'exerce le poids de l'utilisateur par l'intermédiaire d'une manille ou d'un mousqueton. La descente s'effectue en libérant la corde à l'aide de la poignée, juste de la quantité nécessaire grâce à la butée. In the device according to the invention, the descent rope slides, developing friction forces, on fixed parts which delimit a corridor. In addition, the rope is compressed between one of the fixed parts and the articulated part on which the weight of the user is exerted by means of a shackle or a carabiner. The descent is carried out by releasing the rope using the handle, just the amount necessary thanks to the stop.
Le dessin annexé illustre un mode de réalisation du dispositif conforme à la présente invention. The accompanying drawing illustrates an embodiment of the device according to the present invention.
Tel qu'il est représenté, le dispositif comporte, dans un même plan, un ensemble de pièces fixes l'délimitant un couloir, ainsi qu'une pièce articulée 2 prolongée par une poignée 3. Une manille 4, solidaire de la pièce articulée 2, sert à la fixation du dispositif soit au baudrier de l'utilisateur soit à un balcon de l'immeuble à évacuer. As shown, the device comprises, in the same plane, a set of fixed parts delimiting a corridor, as well as an articulated part 2 extended by a handle 3. A shackle 4, integral with the articulated part 2 , is used to fix the device either to the user's harness or to a balcony of the building to be evacuated.
Une plaque de fermeture 5 pivote autour du mëme axe que la pièce articulée 2. En position fermée, elle est maintenue en place par une vis fixe 6 et un verrou de sécurité 7. A closing plate 5 pivots about the same axis as the articulated part 2. In the closed position, it is held in place by a fixed screw 6 and a safety lock 7.
En position ouverte, la rotation de la plaque de fermeture 5 provoque également la rotation de la pièce articulée 2 et de la poignée 3 par simple poussée sur l'axe de la manille 4, ce qui permet d'engager la corde 9 dans l'appareil. In the open position, the rotation of the closure plate 5 also causes the articulation 2 and the handle 3 to rotate by a simple push on the axis of the shackle 4, which makes it possible to engage the rope 9 in the apparatus.
La corde de descente 9 glisse-avec frottement dans le couloir et passe sur la tête de la pièce articulée 2 qui fait office de frein. La forcede freinage est développée par le poids de l'utilisateur. The descent rope 9 slides-with friction in the corridor and passes over the head of the articulated piece 2 which acts as a brake. The braking force is developed by the weight of the user.
Quand l'utilisateur accroche la manille 4 à son baudrier, l'extrémité 10 de la corde 9 est fixée au balcon de l'immeuble. L'utilisateur commande alors sa descente à l'aide de la poignée 3. When the user hooks the shackle 4 to his harness, the end 10 of the rope 9 is fixed to the balcony of the building. The user then controls his descent using the handle 3.
Le dispositif peut également être accroché par la manille 4 au balcon de l'immeuble ; l'extrémité 10 de la corde 9 étant alors fixée au baudrier de la personne à évacuer. Une tierce personne actionne la poignée 3 depuis le balcon. The device can also be hung by the shackle 4 on the balcony of the building; the end 10 of the rope 9 is then attached to the harness of the person to be evacuated. A third person operates handle 3 from the balcony.
Dans les deux cas, l'axe de la manille 4 vient buter, lors de la rotation de la poignée 3, sur une encoche 8 de la plaque de fermeture 5, de façon que la pièce articulée 2 exerce en permanence une pression minimale sur la corde 10. In both cases, the axis of the shackle 4 abuts, during the rotation of the handle 3, on a notch 8 of the closure plate 5, so that the articulated part 2 constantly exerts a minimum pressure on the rope 10.
Le dispositif, objet de l'invention, conçu pour l'évacuation d' immeubles en feu, peut etre utilisé efficacement dans d'autres circonstances, notamment pour l'évacuation d'urgence de ponts roulants ou de grues, l'évacuation de télécabines en panne, le secours en montagne, la spëléo- logie. The device, object of the invention, designed for the evacuation of burning buildings, can be used effectively in other circumstances, in particular for the emergency evacuation of overhead cranes or cranes, the evacuation of cable cars broken down, mountain rescue, speleology.
