Abstract

The barrier has a central portion (2) articulated on hinges (3) that are fixed on a working surface side, where the barrier serves as a manual assisted hoisting assembly folded in a portfolio underside of a ground closing buffer. The hinges are integrated with two lateral panels (4). The panels are articulated on the central portion with normal rotation that is blocked in preferred folded or unfolded positions by notching support surfaces of pin edge bands (5), and is unblocked for requirements of placements on the panels by a vertical traction.

Description

La présente invention concerne un ensemble escamotable du genre barrière articulée adaptable à tout les types d'ouvrages à obturation par tampons articulés à relevage assisté ou non, qui ferment l'accès d'ouvrages souterrains, destiné après ouverture des tampons à être déployé aux fins de signaler danger et interdire toute chute accidentelle. Cet ensemble normalement replié en portefeuille en sous face du tampon en appui sur des butées (1) fixées sur l'ouvrage, garanti la sécurité antichute accidentelle des intervenants dés l'ouverture, est relevable par un quelconque moyen de préhension poignée de levage (9) ou sangle ; il peut être, selon ses dimensions ou son poids, assisté au relevage par tout dispositif de compensation, vérin a gaz (8), contrepoids ou ressorts. Cet ensemble est composé d'une partie centrale (2), qui selon la longueur de l'ouvrage peut être constitué de un ou de plusieurs panneaux rendus solidaires par un quelconque dispositif de liaison rigide (verrou basculant, targette) après leur relevage autour de charnières (3) fixées sur l'ouvrage coté ouvrant du tampon et de deux panneaux latéraux (4) articulés par des paumelles a broches (5) sur la partie centrale et repliables sous cette dernière. Un crantage montré fig. 3 réalisé sur les appuis des paumelles permet l'indexation des panneaux latéraux (4) sur la partie centrale (2) dans les positions préférentielles du tout replié, pour permettre l'effacement de l'ensemble dans l'ouvrage ou du déployé pour la mise en sécurité de l'accès ouvert, un débattement limité des paumelles permettant par une simple traction verticale sur les dits panneaux latéraux de dégager les crans d'indexation et de passer d'une position à l'autre. Au déploiement, chacun des deux panneaux latéral vient se positionner sur des doigts arrêtoirs à effacement par ressorts (6) solidaire de l'ouvrage, le verrouillage en position de sécurité s'effectuant automatiquement avec la redescente en place des crans dans leurs logements. Chaque panneau constitué d'une ossature tubulaire, portant paumelles et charnières est contreventé par un panneau de remplissage antichute (7) Les dessins annexés illustrent l'invention. The present invention relates to a retractable assembly of the articulated barrier type adaptable to all types of works by plugging articulated buffers assisted or not, which close access to underground structures, intended after opening the pads to be deployed for the purposes signal danger and prohibit accidental falls. This set normally folded in the wallet in the underside of the buffer resting on abutments (1) fixed on the structure, guaranteed the accidental fall prevention of the interveners from the opening, can be lifted by any means of grasping lifting handle (9 ) or strap; it can be, according to its dimensions or its weight, assisted to the lifting by any device of compensation, gas cylinder (8), counterweight or springs. This set consists of a central portion (2), which according to the length of the structure may consist of one or more panels secured by any rigid connection device (tilting bolt, bolt) after their lifting around hinges (3) fixed on the side work opening buffer and two side panels (4) articulated by hinges pin (5) on the central part and foldable under the latter. A notch shown in fig. 3 made on the supports of the hinges allows the indexing of the side panels (4) on the central part (2) in the preferred positions of the all folded, to allow the erasure of all in the book or the deployed for the securing the open access, a limited movement of the hinges allowing a simple vertical traction on said side panels to clear the indexing notches and move from one position to another. At deployment, each of the two side panels is positioned on fingers erasing fingers springs (6) integral with the structure, locking in the safety position is automatically performed with the descent in place of the notches in their housing. Each panel consisting of a tubular frame, bearing hinges and hinges is braced by a fall protection panel (7) The accompanying drawings illustrate the invention.

FIG. 2 represents the assembly after raising the side panels deployed for security purposes. - Figure 3 shows the principle of indexing the hinges by notches.

Claims

CLAIMS1- Adaptable barrier on the underside of the articulated floor pads, intended for the access security fence when open for intervention, characterized in that it is a manual assisted lift assembly, formed of a central part (2) hinged on hinges (3) fixed on the side of the book opening opening buffer on which are articulated two side panels (4) foldable wallet for the purpose of their erasure in the book and deployable to positioning and stopping fingers (6) for securing the open access and in that the articulation between the central portion (2) and the side panels (4) is of the type of spindle hinge (5) rotation normally locked in the preferred positions of the folded or deployed by a notching of the bearing faces of the hinges, unlockable for the purposes of implementation by vertical traction on the side panels.

2- articulated safety barrier according to claim 1 characterized in that the central portion (2) may be along the length of the access to be protected consists of one or more panels lift one by one and secured after lifting by a rigid connection lock type.

3- articulated safety barrier according to claim 1 and claim 2 characterized in that the lifting of the central portion allows the deployment of the side panels (4) to their preferred position of securing the structure by snap positioning fingers (6) and recrabotage when going down on their supports. 1/3
