Par ailleurs, le temps d'assemblage pénalise le prix de revient. In addition, the assembly time penalizes the cost price.
L'invention se propose d'apporter une solution. The invention proposes to provide a solution.
A cet effet, l'invention a pour objet un dispositif de sécurité comprenant un support destiné à être monté sur une structure, notamment, sous toiture, ce support comprenant un pied surmonté d'une tige dont l'extrémité est destinée à dépasser de la toiture et à recevoir un organe d'accrochage, ce dispositif étant caractérisé en ce que la tige est reliée au pied par un moyen d'assemblage du type To this end, the invention relates to a safety device comprising a support intended to be mounted on a structure, in particular, under roof, this support comprising a foot surmounted by a rod whose end is intended to protrude from the roof and to receive a fastening member, this device being characterized in that the rod is connected to the foot by an assembly means of the type
démontable.removable.
L'invention sera bien comprise à l'aide de la description ci-après faite à titre The invention will be better understood with the aid of the description below made by way of
d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement: - figure l: coupe d'une toiture, non-limiting example with regard to the attached drawing which schematically represents: FIG. 1: section of a roof,
- figures 2 à 4: différentes versions d'un dispositif de sécurité. - Figures 2 to 4: different versions of a safety device.
En se reportant au dessin, on voit un dispositif 1 de sécurité comprenant un support 2 destiné à être monté sur une structure sous une couverture, ce support comprenant un pied 3 surmonté d'une tige 4 dont l'extrémité est destinée à Referring to the drawing, we see a safety device 1 comprising a support 2 intended to be mounted on a structure under a cover, this support comprising a foot 3 surmounted by a rod 4 the end of which is intended to
dépasser de la toiture et à recevoir un organe 5 d'accrochage. protrude from the roof and receive a fastening member 5.
L'organe S d'accrochage peut être un anneau 5 monté amovible ou solidaire The attachment member S can be a ring 5 mounted removably or securely
de la tige.of the stem.
Ce support est fixé, par exemple, par des boulons sur les poutrelles 6 This support is fixed, for example, by bolts on the beams 6
notamment en acier qui supportent la couverture 7 ou le bac acier 7. especially in steel which support the cover 7 or the steel tank 7.
On voit notamment qu'il existe un espace entre le dessous de la toiture et la We see in particular that there is a space between the underside of the roof and the
poutrelle précitée.aforementioned beam.
Selon l'invention, la tige 4 est reliée au pied 3 par un moyen 8 d'assemblage. Par moyen d'assemblage, on comprendra un moyen d'assemblage du type démontable du type vis/écrou ou système à baőnnette (verrouillage par quart de -3 tour) ou verrouillage rapide par des billes ou rouleaux qui se positionnent dans des gorges. Ce type de montage est bien connu de l'homme du métier et ne sera pas décrit. Accessoirement, un adhésif assurera un non démontage accidentel de la tige. L'avantage de cette solution technique consiste dans le fait qu'elle permet de poser, par le dessous, les pieds 3 sur la structure résistante puis, postérieurement à la mise en place de la couverture, d'effectuer, dans la couverture, un trou 9 au dimension exacte de la section de la tige pour la mettre According to the invention, the rod 4 is connected to the foot 3 by an assembly means 8. By assembly means, there will be understood a means of assembly of the removable type of the screw / nut or bayonet system type (locking by quarter of -3 turn) or quick locking by balls or rollers which are positioned in grooves. This type of assembly is well known to those skilled in the art and will not be described. Incidentally, an adhesive will ensure non accidental disassembly of the rod. The advantage of this technical solution consists in the fact that it makes it possible to place, from below, the feet 3 on the resistant structure then, after the installation of the cover, to carry out, in the cover, a hole 9 to the exact dimension of the section of the rod to put it
en place depuis l'extérieur.in place from the outside.
En limitant la dimension du trou, on facilitera la mise en place d'une étanchéité. By limiting the size of the hole, it will facilitate the establishment of a seal.
Cela sera d'autant plus facile que la tige 4 sera de section circulaire. This will be all the easier as the rod 4 will be of circular section.
Il suffira alors de placer une bague 10 d'étanchéité. It will then suffice to place a sealing ring 10.
Compte tenu de la découpe relativement petite, la couverture ne sera pas affaiblie. Dans une version préférentielle, le haut de la tige sera équipé d'un guide 11 Due to the relatively small cut, the coverage will not be weakened. In a preferred version, the top of the rod will be fitted with a guide 11
gouttes d'eau.water drops.
Ce guide 11 présente une face 11A inférieure en forme de cône de sorte que l'eau ruisselante tombera à distance de la tige, la dimension extérieure du This guide 11 has a bottom face 11A in the form of a cone so that the dripping water will fall away from the rod, the external dimension of the
guide étant supérieure à la section de la tige. guide being greater than the cross section of the rod.
Comme on peut le voir, ce guide est présenté, dans une forme de réalisation, par une pièce massive (figure 2) venant s'emboîter sur le haut de la As we can see, this guide is presented, in one embodiment, by a massive piece (Figure 2) which fits onto the top of the
tige ou par un feuillard (figure 3). rod or by a strip (figure 3).
Cela permet d'obtenir une assise relativement large lorsque le dispositif est This provides a relatively wide seat when the device is
utilisé avec une ligne de vie et d'améliorer la résistance. used with a lifeline and improve resistance.
Cette solution technique offre un avantage supplémentaire dans le mode de fabrication. En effet, du fait d'un support en deux pièces, le pied peut être formé par This technical solution offers an additional advantage in the manufacturing mode. Indeed, due to a support in two pieces, the foot can be formed by
forgeage à chaud et donc fournir un dispositif d'une résistance supérieure. hot forging and therefore provide a device of superior strength.
- 4 En effet, le forgeage à chaud permet de repousser la matière et donc de constituer le départ de la tige du support portant une fraction du moyen - 4 Indeed, hot forging makes it possible to repel the material and therefore to constitute the start of the support rod carrying a fraction of the means
d'assemblage avec le reste de la tige. assembly with the rest of the rod.
Il s'agit d'une méthode de production économique. It is an economical production method.
Le support peut être perpendiculaire à l'axe de la tige ou parallèle (figure 4). -5 The support can be perpendicular to the axis of the rod or parallel (Figure 4). -5
