The anchor has a hooked piece (60) with a rounded cradle base (64) to take the horizontal rail to be fixed to the wall and a rail lock (15) and disengager (63). The bolt or screw that fixes the anchor to the wall traverses a socket (66) welded axially perpendicular to the wall to project behind the hook vertical part. The L piece (61) bearing on the wall has a vertical part (67) welded to the socket and a horizontal part (68) with a rounded end (69) that matches and is welded to the hook curvature.

Description

Le présent certificat d'addition concerne un perfectionnement aux dispositifs d'accrochage à une paroi verticale de moyens aidant la construction, l'entretien et/ou la sécurité, tels qutéchafaudage, nacelle, passerelle avec barrière de sécurité ou autres, composés d'au moins deux organes femelles scellés d demeure dans la paroi, sensiblement au même niveau, et d'autant d'organes mâles se fixant dans les organes femelles et comportant des moyens d'accrochage et de verrouillage d'objets d suspendre, notamment des lisses, lesdits organes mâles comportant un moyen d'appui d la paroi verticale sous l'organe femelle. Elle concerne plus particulièrement la forme du moyen d'accrochage conçue de manière nouvelle. This certificate of addition relates to an improvement to the devices for attaching to a vertical wall of means aiding construction, maintenance and / or security, such as scaffolding, nacelle, gangway with safety barrier or the like, composed of at least at least two female organs sealed in the wall, substantially at the same level, and as many male organs fixing themselves in the female organs and comprising means for hooking and locking hanging objects, in particular stringers, said male members comprising means for supporting the vertical wall under the female member. It relates more particularly to the shape of the hooking means designed in a new way.

Problème posé.Problem.

I1 s'agissait de faciliter la manoeuvre du dispositif d'ancrage, de mieux caler la lisse dans le dispositif d'accrochage et d'augmenter la résistance dynamique de celui-ci. It was a question of facilitating the operation of the anchoring device, of better wedging the stringer in the attachment device and of increasing the dynamic resistance of the latter.

Etat de 7.a technique antérieure et inconvénients.State of 7.a prior art and disadvantages.

L'étant de la technique en la matière est illustré par la demande de brevet français n077 07433 du 4 mars 1977 ainsi que par ses certificats d'addition 78 04992, du 16 février 1978 et 82 06214 déposé le 31 mars 1982 par le demandeur. Celui-ci a aussi obtenu le brevet belge n0874.213 du 15 mars 1979. Ces brevets prévoient l'association d'organes mâles b des organes femelles, l'organe m le se fixant dans l'organe femelle généralement par serrage et expansion d'un dispositif nécessitant une broche pour le vissage. The extent of the technique in the matter is illustrated by the French patent application n077 07433 of March 4, 1977 as well as by its certificates of addition 78 04992, of February 16, 1978 and 82 06214 filed on March 31, 1982 by the applicant. The latter also obtained Belgian patent n0874.213 of March 15, 1979. These patents provide for the association of male organs to female organs, the organ m fixing itself in the female organ generally by clamping and expansion of '' a device requiring a spindle for screwing.

Le demandeur est aussi titulaire de la demande 81 21429
du 10 novembre 1981 où l'accrochape se fait par un dispositif à fixation par quart de tour.
The applicant is also the owner of the application 81 21429
of November 10, 1981 where the hanging is done by a quarter-turn fixing device.

Dans tous ces dispositifs, il existe un crochet qui prend appui contre le mur sous 1 'organe femelle et dans lequel on peut passer la lisse et l'y bloquer par une broche. Ce crochet est réalisé par plusieurs pièces orthogonales soudées (généralement cinq, souvent des tronçons de tubes rectangulaires). La fabrication est donc onéreuse et la résistance dynamique est sujette à la résistance des soudures. In all these devices, there is a hook which bears against the wall under one female member and through which the beam can be passed and blocked there by a pin. This hook is produced by several welded orthogonal pieces (generally five, often sections of rectangular tubes). Manufacturing is therefore expensive and the dynamic resistance is subject to the resistance of the welds.

On a donc cherché à diminuer le prix de revient de ce dispositif et surtout à en augmenter la résistance mécanique. We have therefore sought to reduce the cost price of this device and above all to increase its mechanical strength.

E=posd de
Pour parvenir à ce résultat, on a réalisé un dispositif d'accrochage caractérisé par la combinaison
de deux pièces imbriquées a) l'une en forme de crochet à base arrondie en forme de berceau, pour recevoir notamment une lisse, et, à Sa partie supérieure, présentant un décrochement pour dégager le dessus du crochet et pouvoir y placer la tête de commande du dispositif de serrage qui traverse ledit crochet par une douille soudée à axe perpendiculaire à la paroi et faisant saillie derrière la partie verticale du crochet, b) l'autre, en forme de L avec une barre verticale soudée à la douille et s'appliquant sur la paroi, et une barre horizontale se terminant par un arrondi épousant celui du crochet et soudée à celui-ci.
E = posd of
To achieve this result, a hanging device has been produced, characterized by the combination
of two nested parts a) one in the form of a hook with a rounded base in the form of a cradle, to receive in particular a heald, and, at its upper part, having a recess to release the top of the hook and to be able to place the head therein control of the clamping device which passes through said hook by a welded socket with an axis perpendicular to the wall and protruding behind the vertical part of the hook, b) the other, L-shaped with a vertical bar welded to the socket and s' applying to the wall, and a horizontal bar ending in a rounded shape matching that of the hook and welded to it.

La douille sert d'entretoise entre la pièce en forme de crochet et la pièce en forme de L auquelle elle est soudée. Débouchant de part et d'autre du dispo sitir elle sert de passage à un moyen de blocage dans l'organe femelle scellé dans la paroi, tel qu'une vis ou autre. The sleeve serves as a spacer between the hook-shaped part and the L-shaped part to which it is welded. Opening on either side of the dispo sitir it serves as a passage for a locking means in the female member sealed in the wall, such as a screw or the like.

Solution au problèmes avantaRes et résultat industriel.Solution to advantageous problems and industrial result.

Le dispositif de l'invention permet-de serrer plus facilement la poignée de serrage sans être gênée. The device of the invention makes it easier to tighten the tightening handle without being hindered.

Le berceau épouse convenablement la forme de la lisse.The cradle conforms properly to the shape of the stringer.

Toutefois, une de ses plus grandes qualités est par la triangulation qu'il réalise qui permet d'augmenter la résistance dynamique. I1 y a moins de risque de rupture de soudure et, si ceci arrivait, le risque serait limité. D'ailleurs, on a constaté une résistance dynamique plus que doublée par rapport au crochet classique défini précédemment. However, one of its greatest qualities is the triangulation it achieves, which increases dynamic resistance. There is less risk of weld failure and, if this were to happen, the risk would be limited. Moreover, we have found a dynamic resistance more than doubled compared to the conventional hook defined above.

Par ailleurs, le crochet se fabrique essentiellement à la presse pour le perçage des trous et le façon- nage ce qui écrouit le métal et le rend plus résistant. In addition, the hook is mainly produced by the press for drilling holes and shaping which hardens the metal and makes it more resistant.

Le temps de la fabrication est d'ailleurs considérablement réduit et le positionnement pour les soudures est grandement facilité.The manufacturing time is also considerably reduced and the positioning for the welds is greatly facilitated.

L'invention sera mieux comprise à l'aide de la description suivante qui en donne un exemple non limi tatif de réalisation pratique et qui est illustré par le dessin joint dans lequel
La figure 1 est une vue en perspective du dispositif seul.
The invention will be better understood using the following description which gives a nonlimiting example of practical implementation and which is illustrated by the attached drawing in which
Figure 1 is a perspective view of the device alone.

La figure 2 est une vue schématique du dispo sitif accroché à une paroi et soutenant une lisse. Figure 2 is a schematic view of the device attached to a wall and supporting a rail.

Description d'un mode de réalisation.Description of an embodiment.

Le dispositif d'accrochage à la paroi (2) comporte, dlune façon générale, un moyen d'accrochage (53), un moyen de verrouillaze (15) et un moyen d'appui (54) à la paroi verticale (2). The device for hooking to the wall (2) generally comprises a hooking means (53), a locking means (15) and a support means (54) for the vertical wall (2).

La caractéristique du dispositif de l'lnven- tion est qu'il se décompose en deux pièces (60) et (61), la pièce (60) ayant une forme de crochet et la pièce (61) ayant une forme de L. The characteristic of the device of the invention is that it breaks down into two parts (60) and (61), the part (60) having a hook shape and the part (61) having an L shape.

La pièce a une base arrondie en berceau pour pouvoir recevoir, notamment, une lisse (62), et sa partie supérieure présente un décrochement (63) pour dégager le dessus du crochet (64) et pouvoir y placer la tête de commande (65) du dispositif de serrage qui traverse le crochet (64) et en particulier la pièce (60) par une douille (66), 8 axe perpendiculaire à la paroi (2) et qui fait une saillie derrière la partie verticale de la pièce (60) et être soudée à la pièce (61) comme il va être expliqué. The part has a rounded cradle base to be able to receive, in particular, a heald (62), and its upper part has a recess (63) to release the top of the hook (64) and to be able to place the control head (65) there. of the clamping device which passes through the hook (64) and in particular the part (60) by a sleeve (66), 8 axis perpendicular to the wall (2) and which projects behind the vertical part of the part (60) and be welded to the part (61) as will be explained.

La pièce (61) a une barre verticale (67) qui est soudée à la douille (66) et s'applique sur la paroi (2). Elle a une barre horizontale (68) qui se termine par un arrondi (69) épousant le meme arrondi que le crochet (64) et qui est soudé à celui-ci par deux cordons tels que (70).  The part (61) has a vertical bar (67) which is welded to the sleeve (66) and is applied to the wall (2). It has a horizontal bar (68) which ends in a rounding (69) matching the same rounding as the hook (64) and which is welded thereto by two cords such as (70).

Lorsque le dispositif de l'invention est accroché à la paroi (2), on peut y placer la lisse (62) et on emprisonne celle-ci par une broche (15) qui traverse deux trous (71) et (72) du crochet. Elle est empechée de s'en échapper par une goupille (73) traversant un trou d'extrémité (74) de la broche (15). Celle-ci est retenue par une chaînette (75) qui retient aussi la goupille (73). When the device of the invention is hooked to the wall (2), the rail (62) can be placed there and the latter is trapped by a pin (15) which passes through two holes (71) and (72) of the hook . It is prevented from escaping by a pin (73) passing through an end hole (74) of the spindle (15). This is retained by a chain (75) which also retains the pin (73).

On comprend que l'ensemble des deux pièces (60) et (61) soudées ensembles suivant les cordons de soudure tels que (70) et par la douille telle que (66) et une nervure telle que (76) forme un ensemble indéformable. Blême si l'une des soudures venait à se rompre, l'ensemble ne se dissocierait pas et continuerait à jouer son rôle. Seule une rupture totale pourrait provoquer la défaillance du dispositif.  It is understood that the assembly of the two parts (60) and (61) welded together according to the weld beads such as (70) and by the sleeve such as (66) and a rib such that (76) forms a non-deformable assembly. Pale if one of the welds breaks, the assembly will not dissociate and will continue to play its role. Only a total rupture could cause the device to fail.
