Description
Equipement de sécurité. Les moyens de sécurité utilisés habituelle ment pour retenir les travailleurs victimes de chutes dans l'exercice de leur métier (cou vreurs, charpentiers, etc.) présentent les in convénients, soit d'obliger le travailleur d'in terrompre fréquemment son travail, en parti culier lorsqu'il doit tenir une corde à la main, soit, s'ils sont fixés en permanence au travail leur, de ne pas amortir le<I>choc</I> de retenue.
L'équipement de sécurité, objet de la pré sente invention, a pour but de remédier à ces inconvénients. Il est caractérisé en ce qu'il comporte un organe de liaison souple relié à une de ses extrémités, par l'intermédiaire d'un ressort, à des moyens destinés à être amarré à un point fixe et fixé à son autre extrémité à un dispo sitif d'attache pour le corps humain.
Ce dispositif d'attache peut être constitué par une plaque dorsale à laquelle est. fixée au moins une courroie destinée à entourer le tronc du corps humain, l'organe de liaison étant fixé au moins à ladite courroie dans la partie de celle-ci solidaire (le la plaque dor sale. L'équipement muni d'un tel dispositif d'attache présente encore l'avantage de laisser le travailleur parfaitement. libre de ses mou- Le dessin annexé représente, à titre d'exemple, une forme de réalisation de l'équi pement de sécurité selon l'invention, muni d'un dispositif d'attache tel qu'il vient d'être indiqué.
L'équipement représenté est constitué par une corde 1, fixée à l'une de ses extrémités à un ressort à boudin 2 en acier, dont la résis tance lui permet de supporter un poids de mille kilos. Ce ressort est fixé lui-même à un anneau 3 et passé dans une courroie 4 laquelle constitue les moyens d'amarrage de l'équipe ment.
La corde 1 est fixée à son autre extrémité à un anneau 5 par lequel elle est reliée au dispositif d'attache pour le corps humain.
Ce dispositif est constitué par une plaque dorsale 6 et deux courroies 7 et 8. L'anneau 5 passe dans la courroie 7, laquelle est fixée à la plaque dorsale 6 à la partie supérieure de cette plaque. La courroie 8 est fixée à la partie inférieure de la plaque dorsale 6. Une pièce de renforcement 9 s'étend dans la partie médiane de la plaque 6 entre l'anneau 5 et la courroie 8. Les courroies 7 et 8 sont destinées à entourer le tronc de 1-'usager.
La plaque dorsale 6, les courroies 7 et 8 de même que la pièce 9 peuvent être en cuir. Voici comment on utilise l'équipement dé crit L'ouvrier appelé à travailler en un endroit où il risque de faire une chute, amarre l'équi pement à un point fixe, dans le cas du dessin une cheminée 10, à l'aide de la courroie 4. Il s'attache lui-même à l'aide des courroies 7 et 8, en prenant soin que la plaque dorsale 6 se trouve dans son dos, la boucle 5 étant près de ses omoplates. En cas de chute de l'ouvrier, il sera retenu par la corde et le choc d'arrêt sera amoindri par le ressort 2.
L'organe de liaison souple qui a été décrit comme étant une corde pourrait évidemment être un câble.
Pour donner à l'équipement encore plus de sécurité et éviter tout accident en cas de rup ture du ressort 2, une chaîne peut être logée à l'intérieur du ressort et relier ses deux extré mités, tout en le laissant libre de s'allonger.
Security equipment. The means of safety usually used to retain workers who are victims of falls in the exercise of their profession (roofers, carpenters, etc.) have the disadvantages, either of forcing the worker to stop his work frequently, by particularly when it is necessary to hold a rope in the hand, ie, if they are permanently attached to their work, not to absorb the <I> shock </I> of restraint.
The purpose of the safety equipment which is the subject of the present invention is to remedy these drawbacks. It is characterized in that it comprises a flexible connecting member connected at one of its ends, by means of a spring, to means intended to be moored to a fixed point and fixed at its other end to a dispo attachment for the human body.
This attachment device can be constituted by a back plate to which is. fixed at least one belt intended to surround the trunk of the human body, the connecting member being fixed at least to said belt in the part of the latter integral (the dirty gold plate. The equipment provided with such a device attachment also has the advantage of leaving the worker perfectly free of his movements. The accompanying drawing shows, by way of example, one embodiment of the safety equipment according to the invention, provided with a fastening device as just indicated.
The equipment shown is constituted by a rope 1, fixed at one of its ends to a coil spring 2 made of steel, the strength of which enables it to support a weight of one thousand kilograms. This spring is itself fixed to a ring 3 and passed through a belt 4 which constitutes the means for mooring the equipment.
The rope 1 is attached at its other end to a ring 5 by which it is connected to the attachment device for the human body.
This device consists of a back plate 6 and two belts 7 and 8. The ring 5 passes through the belt 7, which is fixed to the back plate 6 at the upper part of this plate. The belt 8 is attached to the lower part of the back plate 6. A reinforcement piece 9 extends in the middle part of the plate 6 between the ring 5 and the belt 8. The belts 7 and 8 are intended to surround the trunk of 1-user.
The back plate 6, the straps 7 and 8 as well as the part 9 can be made of leather. Here is how the equipment described is used The worker called upon to work in a place where there is a risk of falling, anchors the equipment to a fixed point, in the case of drawing a chimney 10, using strap 4. He attaches himself using straps 7 and 8, taking care that back plate 6 is behind his back, with buckle 5 near his shoulder blades. If the worker falls, he will be retained by the rope and the stopping shock will be lessened by the spring 2.
The flexible connecting member which has been described as being a rope could obviously be a cable.
To give the equipment even more safety and to avoid any accident in the event of breakage of the spring 2, a chain can be housed inside the spring and connect its two ends, leaving it free to lie down. .
