DISPOSITIF DE SECURITE CONTRE LE RISQUE DE CHUTE DESAFETY DEVICE AGAINST THE RISK OF FALLING
PERSONNES DANS LA CAGE D'ASCENSEUR.PEOPLE IN THE ELEVATOR CAGE.
La présente invention concerne un dispositif de sécurité contre le risque de chute de personnes dans la cage vide de l'ascenseur, en cas d'ouverture accidentelle de la porte palière. The present invention relates to a safety device against the risk of people falling into the empty elevator shaft, in the event of accidental opening of the landing door.
De façon classique, lorsqu'une cabine d'ascenseur arrive à un étage, elle commande automatiquement un mécanisme de déverrouillage de la serrure de la porte palière se trouvant à cet étage. Comme tout mécanisme, ce système peut connaître de défaillances et laisser la porte palière non-verrouillée lors du départ de l'ascenseur, ce qui constituerait un grave danger pour les utilisateurs. Conventionally, when an elevator car arrives on a floor, it automatically controls a mechanism for unlocking the lock of the landing door located on this floor. Like any mechanism, this system can fail and leave the landing door unlocked when the lift leaves, which would constitute a serious danger for users.
De même, la réglementation en vigueur exige que dans les cas d'urgence les portes palières puissent être ouvertes au moyen d'une commande manuelle actionnable de l'extérieur, commande qui, soit par mégarde soit par malveillance, peut laisser la porte palière non-verrouillée sans que l'ascenseur soit présent ce qui constitue un risque majeur pour les utilisateurs. Likewise, the regulations in force require that in emergency cases the landing doors can be opened by means of a manual control operable from the outside, a control which, either inadvertently or maliciously, can leave the landing door -locked without the elevator being present which constitutes a major risk for users.
Afin d'apporter une solution aux problèmes ci-dessus, la présente invention décrit un dispositif de sécurité contre le risque de chute de personnes dans la cage d'ascenseur, 25 dispositif qui comporte un système de sangles qui, en se déroulant automatiquement en cas de l'ouverture de la porte palière sans que l'ascenseur soit présent, fait barrage vers la cage vide d'ascenseur, et il se caractérise en ce qu'il comprend: Au moins une sangle de sécurité, montée dans la porte palière à l'intérieur d'un boîtier dans lequel un mandrin est monté à rotation sur un support, sur lequel est enroulée la sangle de sécurité, ledit mandrin étant sollicité par un ressort dans le sens de l'enroulement de la sangle et par un dispositif de verrouillage qui, en cas de choc sur la sangle, bloque le mandrin en rotation pour empêcher le déroulement de la sangle. A l'extrémité extérieure de la sangle est montée une boucle qui, lorsque la cabine ne se trouve pas au niveau de la porte palière, permet le verrouillage automatique de la sangle à l'aide d'un dispositif classique monté soit dans l'huisserie de la porte 10 palière, soit dans la porte coulissante opposée. In order to provide a solution to the above problems, the present invention describes a safety device against the risk of people falling into the elevator shaft, a device which comprises a system of straps which, taking place automatically in the event of from the opening of the landing door without the elevator being present, forms a barrier towards the empty elevator shaft, and it is characterized in that it comprises: At least one safety strap, mounted in the landing door at the interior of a housing in which a mandrel is rotatably mounted on a support, on which the safety strap is wound, said mandrel being biased by a spring in the direction of the winding of the strap and by a device lock which, in the event of an impact on the strap, blocks the rotating mandrel to prevent unwinding of the strap. At the outer end of the strap is mounted a loop which, when the cabin is not at the level of the landing door, allows the automatic locking of the strap using a conventional device mounted either in the frame of the landing door 10, ie in the opposite sliding door.
Ainsi, en cas d'ouverture accidentelle de la porte palière, au moins deux sangles de sécurité, hauteur enfant et hauteur adulte, en se déroulant, s'opposent à tout passage vers la cage vide de l'ascenseur, sans toute fois empêcher les 15 opérations de secours ou d'entretien normales. Thus, in the event of accidental opening of the landing door, at least two safety straps, child height and adult height, when unrolling, prevent any passage to the empty elevator shaft, without however preventing 15 normal rescue or maintenance operations.
Un exemple non limitatif de mode de réalisation de l'invention sera décrit, avec référence au dessin annexé (figure 1), qui est une vue depuis l'extérieur de l'huisserie d'une porte palière d'ascenseur, munie du 20 système de sécurité proposée, dans lequel: A l'intérieur de la porte palière d'ascenseur (2), est monté un boîtier (3) comportant une sangle de sécurité (1) et un mécanisme enrouleur conventionnel de type véhicule automobile. A l'extrémité extérieure de la sangle (1) est 25 montée une boucle (4) qui, lorsque la sangle est enroulée sur son mandrin reste a l'extérieur du boîtier, ne dépassant pas le gabarit de la porte palière. A nonlimiting example of embodiment of the invention will be described, with reference to the appended drawing (FIG. 1), which is a view from the outside of the door frame of an elevator landing door, fitted with the system. safety device, in which: Inside the elevator landing door (2), is mounted a housing (3) comprising a safety strap (1) and a conventional winding mechanism of the motor vehicle type. At the outer end of the strap (1) is mounted a loop (4) which, when the strap is wound on its mandrel remains outside the housing, not exceeding the gauge of the landing door.
La sangle de sécurité (1), qui est de type véhicule automobile, est recouverte d'une peinture réfléchissante avec des motifs spécifiques, qui la rend visible dans des conditions de visibilité réduites. The safety strap (1), which is of the motor vehicle type, is covered with a reflective paint with specific patterns, which makes it visible in reduced visibility conditions.
Dans l'huisserie de la porte palière (6), est monté un mécanisme classique de verrouillage (5) qui, lorsque la cabine de l'ascenseur n'est pas présente au niveau de la porte palière, rend solidaire la boucle (4) avec l'huisserie de la porte palière (6). Lorsque le mécanisme de verrouillage (5) n'est pas activé, il ne dépasse pas le gabarit de l'huisserie de la porte palière. In the frame of the landing door (6), is mounted a conventional locking mechanism (5) which, when the elevator car is not present at the landing door, makes the loop (4) integral with the door frame (6). When the locking mechanism (5) is not activated, it does not exceed the size of the landing door frame.
En cas d'ouverture de la porte palière, sans que l'ascenseur soit présent à son niveau, la sangle de sécurité (1) se 10 déroule normalement jusqu'à l'ouverture complète de la porte, la boucle (4) étant inamovible et solidaire avec l'huisserie de la porte palière. When the landing door is opened, without the elevator at its level, the safety strap (1) unwinds normally until the door is fully opened, the buckle (4) being irremovable and secured to the landing door frame.
Les caractéristiques connus du mécanisme enrouleur permettant à la fois de bloquer le déroulement de la sangle 15 en cas de choc sur la sangle ou, de l'ouverture précipité d'une porte palière battante, et aussi, d'écarter la sangle de sécurité en cas de nécessité sans toute fois la désolidariser de son mécanisme de verrouillage. The known characteristics of the retractor mechanism making it possible both to block the unwinding of the strap 15 in the event of an impact on the strap or, of the precipitous opening of a swing landing door, and also, to spread the safety strap in if necessary without detaching it from its locking mechanism.
Ainsi, en se déroulant, les sangles de sécurité (1) constituent un barrage matériel visible et permanent, qui s'oppose a tout passage accidentel vers la cage d'ascenseur vide. Thus, by unrolling, the safety straps (1) constitute a visible and permanent material barrier, which prevents any accidental passage towards the empty elevator shaft.
