Abstract

The support consists of a fixed jaw (1) attached to a post (2) with holders (12, 13, 14) for safety rails, and a mobile unit with a locking jaw to grip a roof timber and hold the support in place. The locking jaws is actuated by a knuckle joint between two plates (17, 18), actuated by a lever (6) with a socket (7) on its end to receive the tip (8) of a control bar (9). The mobile unit has a handle (15) for moving it along the post.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention est relative aux dispositifs de sécurité pour les professionnels tels que les couvreurs travaillant sur les toits ou en hauteur sur des édifices. The present invention relates to safety devices for professionals such as roofers working on roofs or at height on buildings.

Des systèmes ont été développés tel celui décrit dans le brevet EP 959 201, mais ces systèmes ne permettent pas une utilisation selon plusieurs configurations. Systems have been developed such as that described in patent EP 959 201, but these systems do not allow use in several configurations.

Le dispositif selon l'invention permet indifféremment la fixation sur les faces supérieures et inférieures d'une pièce de charpente ou sur les faces latérales des dites pièces. The device according to the invention indifferently allows attachment to the upper and lower faces of a structural part or to the lateral faces of said parts.

A cette effet, il comporte un mât solidaire d'une mâchoire fixe, et une mâchoire mobile en translation sur le mât pour venir serrer la pièce de charpente grâce à un dispositif à genouillère. For this purpose, it comprises a mast secured to a fixed jaw, and a jaw movable in translation on the mast to come and clamp the structural part thanks to a toggle device.

Sur le mât sont soudés des tronçons de profilés tubulaires dans lesquels peuvent être insérées des barres de rambardes. On the mast are welded sections of tubular profiles in which can be inserted railing bars.

L'invention sera mieux comprise en référence aux dessins annexés dans lesquels

Figure img00010001

+ Fig. 1 shows the general device according to the invention, and or + FIG. 2 is an exploded view of the part comprising the toggle joint allowing the tightening and locking of the device.

Le dispositif de protection selon l'invention comprend une base formant mâchoire fixe (1) sur laquelle est solidarisé un mât (2), par exemple par soudage. The protection device according to the invention comprises a base forming a fixed jaw (1) on which is fixed a mast (2), for example by welding.

Sur le mât, un bloc mobile peut se déplacer en translation. Le bloc est composé d'une poignée (15) servant au positionnement du bloc mobile, la dite poignée étant solidaire de deux plaques (17,18). On the mast, a movable block can move in translation. The block is composed of a handle (15) used for positioning the movable block, the said handle being integral with two plates (17,18).

Une vis pointeau (16) évite le glissement du bloc mobile sur le mât de serrage. A needle screw (16) prevents the movable block from sliding on the clamping mast.

Les plaques (17,18) sont percées d'un trou permettant le passage de l'axe (4) d'articulation du levier de serrage (6) et de la genouillère (21). The plates (17,18) are pierced with a hole allowing the passage of the axis (4) of articulation of the clamping lever (6) and the toggle joint (21).

Une fente (10) est destinée au passage et au déplacement de l'axe (5) solidaire de la genouillère. A slot (10) is intended for the passage and movement of the axis (5) integral with the toggle joint.

Une butée (11) constituée par une vis réglable dans un support solidaire du bloc mobile donne la position finale du levier (6) en position de serrage. A stop (11) constituted by an adjustable screw in a support integral with the movable block gives the final position of the lever (6) in the clamping position.

Le levier (6) possède un cylindre (7) à son extrémité dans lequel peut être introduite la partie terminale (8) de la tige de commande (9). The lever (6) has a cylinder (7) at its end into which the end part (8) of the control rod (9) can be introduced.

Après serrage du dispositif, cette tige (9) est retirée pour éviter tout risque de déverrouillage accidentel. After tightening the device, this rod (9) is removed to avoid any risk of accidental unlocking.

Des tronçons (12,13, 14) d'éléments tubulaires sont fixés après le mât pour permettre d'y loger des barres telles que celles formant l'ossature d'une rambarde. Sections (12, 13, 14) of tubular elements are fixed after the mast to allow the accommodation of bars such as those forming the framework of a guardrail.

<Desc/Clms Page number 2><Desc / Clms Page number 2>

Une telle barre peut aussi, selon la position du dispositif, être introduite dans le mât, et éventuellement bloquée au moyen de la vis (19).  Depending on the position of the device, such a bar can also be introduced into the mast, and possibly blocked by means of the screw (19).

Lors de l'utilisation, la mâchoire (1) est mise en contact avec une face d'une pièce de charpente telle que ferme, solive, chevron, panne ou poutre. La partie mobile est déplacée contre la face opposée de la pièce grâce à la poignée (15). In use, the jaw (1) is brought into contact with one face of a structural member such as firm, joist, rafter, purlin or beam. The movable part is moved against the opposite face of the part using the handle (15).

La tige de commande (9) est introduite dans le cylindre (7) du levier de serrage (6) qui agit sur la genouillère pour provoquer le serrage, et après passage du point d'équilibre s'appuyer sur la butée (11). The control rod (9) is introduced into the cylinder (7) of the clamping lever (6) which acts on the toggle joint to cause the clamping, and after passing the point of equilibrium rest on the stop (11).

La tige de commande est alors retirée, et les éléments de protection introduits, selon la position du dispositif dans les éléments (2,12, 13,14). The control rod is then removed, and the protective elements inserted, depending on the position of the device in the elements (2,12, 13,14).

Le dispositif selon l'invention est particulièrement destiné aux travaux effectués sur des toits, car il présente l'avantage d'être compact, transportable facilement, et de mise en oeuvre rapide, mais il peut être utilisé pour tous les travaux en hauteur sur des édifices permettant la fixation du dispositif sur des éléments fixes et solides, présentant 2 faces parallèles.The device according to the invention is particularly intended for work carried out on roofs, because it has the advantage of being compact, easily transportable, and of rapid implementation, but it can be used for all work at height on buildings allowing the fixing of the device on fixed and solid elements, having 2 parallel faces.
