Description

La présente invention concerne un dispositif de sécurité assurant la stabilité des échelles par fixation intermédiaire de l'échelle aux structures tubulaires ou rectangulaires d'échafaudage ou garde-corps quelle que soit leur inclinaison.The present invention relates to a safety device ensuring the stability of ladders by intermediate attachment of the ladder to tubular or rectangular scaffolding structures or railings whatever their inclination .

Traditionnellement, les utilisateurs d'échelles sont exposés aux risques de chutes du fait de l'instabilité des échelles. Ces risques concernent d'une part le glissement de l'échelle au niveau de ses deux montants en appui et d'autre part le mouvement de bascule selon une rotation dont le centre est le point d'appui au sol des montants de l'échelle.Traditionally, ladder users are at risk of falling due to the instability of the scales. These risks relate on the one hand to the slippage of the ladder at the level of its two uprights in support and on the other hand the movement of rocks according to a rotation whose center is the fulcrum on the ground of the uprights of the scale.

Le dispositif selon notre invention permet donc de remédier à ces inconvénients car il est conçu de façon à solidariser l'échelle à la stabilité des structures d'échafaudages obligatoirement installées à au moins un mètre au-dessus du plancher de manière à prévenir tout risque de chute des travailleurs. Le dispositif selon notre invention se fixe manuellement et sans outils spéciaux aux structures d'échafaudages ou garde-corps entre le niveau du plancher et la partie supérieure du garde-corps prévus et mis en place d'après les normes de sécurité en vigueur.The device according to our invention therefore makes it possible to remedy these drawbacks because it is designed to secure the ladder to the stability of the structures scaffolding must be installed at least one meter above the floor so as to prevent any risk of workers falling. The device according to our invention attaches manually and without special tools to scaffolding structures or railing between the level of the floor and the upper part of the railing planned and implemented according to current safety standards.

Par ailleurs, le dispositif selon notre invention peut s'utiliser, en raison de sa dissymétrie, dans tous les sens quelque soient la position et l'inclinaison de l'échelle placée par rapport à la structure et inversement. Enfin, lors de l'utilisation du dispositif selon notre invention, sa position n'entrave nullement le libre passage de ses utilisateurs. Furthermore, the device according to our invention can be used, due to its asymmetry, in all directions whatever the position and the inclination of the scale placed in relation to the structure and vice versa. Finally, when using the device according to our invention, its position in no way hinders the free passage of its users.

L'état de la technique antérieur est représenté par le brevet européen n° EP-A-0 171 485 qui permet de mettre en contact des pièces de formes différentes.The state of the prior art is represented by European patent no. EP-A-0 171 485 which allows parts of different shapes to be brought into contact.

Niais ce n'est pas l'objet de la présente demande qui ne cherche pas à mettre en contact deux objets. Celle-ci vise à maintenir deux éléments à une certaine distance l'un de l'autre. On voit que le principe de ces deux produits est différent.However, this is not the subject of this request which does not seek to contact two objects. This aims to keep two elements at a certain distance one of the other. We see that the principle of these two products is different.

Plus intéressant est peut être le brevet US-A-2 392 932. Il décrit un appareil constitué de deux pinces dont l'une est destinée à saisir un tube de section rigoureusement circulaire, l'autre pince se terminant par un crochet. La liaison entre les deux pinces ne permet pas l'adaptation à une échelle.Perhaps more interesting is US-A-2,392,932. It describes an apparatus consisting of two clamps, one of which is intended to grip a section tube strictly circular, the other clamp ending in a hook. The connection between the two clamps do not allow adaptation to a ladder.

Le brevet GB 2.222 629 décrit un dispositif de fixation d'échelle comportant deux pinces réunies par une articulation. Le serrage d'une pince sur l'échelle bloque l'articulation. La fixation par une pince ne procure pas une sécurité sure.GB 2,222,629 describes a ladder fixing device comprising two clamps joined by a joint. Tightening a clamp on the ladder blocks the joint. Clamping does not provide secure security.

La présente invention a donc pour objet un dispositif de sécurité pour échelle permettant de stabiliser celle-ci en la rendant solidaire des structures d'échafaudage, comportant trois éléments solidaires entre eux :

  • un acceptant d'échelle 1 ouvert au moins sur trois de ses faces susceptibles de coulisser le long d'un montant de l'échelle 12 et de se fixer en un endroit approprié de celui-ci ;
  • un tube cylindrique 6 astreint à pivoter autour de l'axe d'une vis papillon 2 de l'acceptant d'échelle,
  • un attaché de structure 3 fixé au dit tube 6, délimitant entre ses parois latérales un espace permettant d'insérer un élément 10 tubulaire ou rectangulaire de l'échafaudage,
   caractérisé en ce que la vis papillon 2 supportant le tube cylindrique 6 se prolonge à travers la paroi de l'acceptant d'échelle en traversant un écrou 5 servant à bloquer manuellement le montant de l'échelle par pression entre les parois de l'acceptant d'échelle et l'extrémité de la vis papillon 2, et en ce que l'attaché de structure 3 est muni de deux fentes différentes aux extrémités de ses faces opposées dont l'une est fermée et englobe la tête 15 de vis 4 quelles que soient les positions de cette dernière tandis que l'autre fente est ouverte et l'autre face est maintenue en position fermée par le serrage de l'écrou papillon 7, retenant ainsi un élément tubulaire 10 ou rectangulaire de l'échafaudage entre les deux décrochés d'angle 9 de l'attaché de structure.The present invention therefore relates to a safety device for a ladder making it possible to stabilize it by making it integral with the scaffolding structures, comprising three elements integral with each other:
  • a ladder acceptor 1 open at least on three of its faces capable of sliding along an upright of the ladder 12 and of being fixed in an appropriate place thereof;
  • a cylindrical tube 6 required to pivot around the axis of a butterfly screw 2 of the scale acceptor,
  • a structural fastener 3 fixed to said tube 6, delimiting between its lateral walls a space allowing the insertion of a tubular or rectangular element 10 of the scaffolding,
characterized in that the butterfly screw 2 supporting the cylindrical tube 6 is extended through the wall of the ladder acceptor by passing through a nut 5 serving to manually block the amount of the ladder by pressure between the walls of the acceptor scale and the end of the butterfly screw 2, and in that the structural attachment 3 is provided with two different slots at the ends of its opposite faces, one of which is closed and includes the head 15 of the screw 4 which whatever the positions of the latter while the other slot is open and the other face is held in the closed position by tightening the wing nut 7, thus retaining a tubular 10 or rectangular element of the scaffolding between the two corner hooks 9 of the structure attaché.

On voit ainsi que le serrage manuel de la vis papillon et de l'écrou bloque l'ensemble du dispositif de sécurité.It can thus be seen that the manual tightening of the butterfly screw and of the nut blocks the entire security system.

Dans une forme de réalisation avantageuse, le dispositif comporte également un frein adapté à la taille de la tête de la vis, de façon à pouvoir bloquer la vis lorsque le dispositif est en position fermée. In an advantageous embodiment, the device also comprises a brake adapted to the size of the screw head, so that the screw can be locked when the device is in the closed position.

D'autres caractéristiques et avantages de la présente invention apparaítront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif, en regard des figures 1 à 3 des dessins ci-joints, et qui fera bien comprendre comment l'invention peut être réalisée.Other characteristics and advantages of the present invention will become apparent from during the description which follows, given by way of nonlimiting example, in look at Figures 1 to 3 of the attached drawings, and which will make it clear how the invention can be realized.
