Description

L'invention se rapporte à une console de dispositifs sécurité tels que des passerelles, garde-corps et filets de protection que l'on veut fixer à une construction pour en faciliter la poursuite de la réalisation ou l'entretien.The invention relates to a console of safety devices such as walkways, guardrails and protective nets that are to be fixed to a construction to facilitate further construction or maintenance.

Elle se rapporte également aux dispositifs de sécurité de ce type incluant de telles consoles et plus particulièrement mais non exclusivement à ceux formés par assemblage d'éléments d'importance et donc de poids limités pour rester portable manuellement.It also relates to security devices of this type including such consoles and more particularly but not exclusively to those formed by assembling elements of importance and therefore of limited weight to remain portable manually.

On connaît déjà de nombreuses consoles répondant à cette exigence et que l'on peut classer en fonction de leur mode d'accrochage en trois types principaux à savoir celles qui se fixent par appui dans un chéneau puis celles qui se suspendent soit par des pattes percées recevant des tiges perpendiculaires à la paroi dans laquelle elles sont ancrées, soit par des crochets coopérant avec une barre horizontale scellée contre le mur et généralement dénommée lisse.We already know many consoles that meet this requirement and that we can classify according to their method of hanging in three main types namely those that are fixed by support in a gutter then those that hang either by pierced legs receiving rods perpendicular to the wall in which they are anchored, either by hooks cooperating with a horizontal bar sealed against the wall and generally called smooth.

Les consoles qui se fixent par appui dans un chéneau comprennent un montant vertical perpendiculairement auquel sont, à des niveaux différents, soudés deux fourreaux parallèles entre eux et guidant en translation deux traverses dont celle du fourreau de niveau inférieur est directement terminée par une chape portant un patin d'appui sur le mur situé sous le chéneau alors que celle du fourreau de niveau supérieur est terminée par un autre fourreau quant à lui parallèle au montant et guidant en translation un poinçon terminé à sa base par une chape portant un patin d'appui sur le fond du chéneau.The brackets which are fixed by support in a gutter include a vertical upright perpendicular to which are, at different levels, welded two sheaths parallel to each other and guiding in translation two crosspieces including that of the lower level sheath is directly terminated by a yoke carrying a support shoe on the wall located under the gutter while that of the upper level sheath is terminated by another sheath which is parallel to the upright and guiding in translation a punch finished at its base by a yoke carrying a support shoe on the bottom of the gutter.

Les translations des traverses et du poinçon permettent de régler la console pour l'adapter aux particularités de la construction.The translations of the crosspieces and the punch allow the console to be adjusted to adapt it to the particularities of the construction.

Pour l'utilisation, ces translations sont ensuite rendues impossibles par des goupilles amovibles traversant les fourreaux et leur traverse ou poinçon.For use, these translations are then made impossible by removable pins passing through the sleeves and their crosspiece or punch.

Ces consoles reçoivent généralement un garde-corps qui se fixe alors sur des prolongements de leur montant qui s'élèvent à cet effet nettement au-dessus de leur traverse supérieure qui, quant à elle, peut éventuellement recevoir un plancher. Les consoles qui se fixent par suspension à des tiges perpendiculaires à la paroi dans laquelle elles sont ancrées comprennent (FR-A-2.488.311) un montant vertical, perpendiculairement à la base duquel est également soudé un fourreau guidant une traverse terminée par une chape adaptée pour maintenir la dite base à une distance prédéterminée du mur par un patin ou un autre moyen tel un étai fixé entre les tableaux d'une fenêtre tandis qu'à la partie supérieure de ce montant sont fixées :

  • - sur sa face arrière, une traverse horizontale dont, de manière à pouvoir supporter un plancher et/ou un garde-corps ou filet de protection, l'extrémité arrière est elle-même supportée par une contrefiche prenant quant à elle appui à la base du montant et,
  • - sur sa face avant, un fourreau dont la face avant, d'une part présente une découpe pour coopérer avec une tige ancrée dans le mur et, d'autre part est apte à loger une rehausse terminée par une plaque du type de celle citée plus haut.
These consoles generally receive a railing which is then fixed on extensions of their amount which rise for this purpose clearly above their upper crosspiece which, in turn, may possibly receive a floor. The brackets which are fixed by suspension to rods perpendicular to the wall in which they are anchored include (FR-A-2,488,111) a vertical upright, perpendicular to the base of which is also welded a sheath guiding a crosspiece ending in a yoke adapted to maintain said base at a predetermined distance from the wall by a skate or other means such as a forestay fixed between the tables of a window while at the top of this amount are fixed:
  • - on its rear face, a horizontal crosspiece of which, so as to be able to support a floor and / or a guardrail or protective net, the rear end is itself supported by a strut taking support for its part at the base the amount and,
  • - On its front face, a sheath whose front face, on the one hand has a cutout to cooperate with a rod anchored in the wall and, on the other hand, is capable of accommodating an extension finished with a plate of the type cited upper.

L'avantage de cette console est que, sans la rehausse, on peut toujours fixer la console sur la tige dont l'organe d'arrêt trouvera place dans le cavalier et, avec la rehausse, on peut rattraper un point d'ancrage situé plus haut et par exemple sous une avancée de toit.The advantage of this console is that, without the riser, you can always fix the console on the rod whose stop member will find place in the rider and, with the riser, you can catch an anchor point located more high and for example under a roof overhang.

Les consoles qui se fixent par suspension à l'aide de crochets coopérant avec une lisse horizontale scellée contre le mur sont semblables à celles ci-dessus, sauf en ce qui concerne la plaque ou le cavalier d'accrochage qui est ici remplacé par des crochets aptes à coiffer la lisse scellée au mur.The brackets which are fixed by suspension using hooks cooperating with a horizontal rail sealed against the wall are similar to those above, except as regards the plate or the hanging jumper which is here replaced by hooks suitable for styling the barrier beam sealed on the wall.

Ainsi donc, ces trois types de consoles diffèrent principalement l'un de l'autre au niveau de leur dispositif de fixation qui nécessite dans le premier type une traverse coulissant au long d'un axe perpendiculaire à la paroi, dans le second type la possibilité d'une rehausse coulissant au long d'un axe vertical et dans le dernier type une possibilité d'accrochage en différents points situés au long d'une lisse d'axe horizontal parallèle à la paroi.Thus, these three types of consoles differ mainly from each other in terms of their fixing device which requires in the first type a cross member sliding along an axis perpendicular to the wall, in the second type the possibility of an extension sliding along a vertical axis and in the last type a possibility of attachment at different points located along a beam of horizontal axis parallel to the wall.

De ce fait, à ce jour, selon les constructions où ils interviennent, les entrepreneurs doivent disposer de consoles spécialement adaptées à chacun de ces trois modes de fixation, ce qui, bien entendu, triple le coût et l'encombrement du matériel et majore incidemment le prix de revient de la construction.Therefore, to date, depending on the construction in which they operate, contractors must have consoles specially adapted to each of these three methods of attachment, which, of course, triples the cost and size of the equipment and increases incidentally the cost of construction.

Un résultat que l'invention vise à obtenir est une console susceptible d'être fixée indifféremment par appui dans un chéneau, par suspension à des tiges ancrées dans le mur ou par suspension à une lisse.A result which the invention aims to obtain is a console capable of being fixed indifferently by support in a gutter, by suspension from rods anchored in the wall or by suspension from a rail.

A cet effet, elle a pour objet une console du type cité plus haut, notamment caractérisée en ce que :

  • - le fourreau est formé par un cavalier dont le fond présente la découpe,
  • - la tige est pourvue d'un organe d'arrêt qui trouve place entre les branches du cavalier,
  • - le perçage du fourreau est positionné de manière telle que, lorsqu'au lieu d'une suspension par une barre verticale, la console est directement suspendue à une tige passant par la découpe du fond du cavalier, la mise en place de cette goupille la fait passer juste sous l'organe d'arrêt de sorte qu'elle empêche alors à la fois le dégagement de la tige de la découpe et la rotation dudit organe d'arrêt et,
  • - les branches du cavalier présentent chacune à leur base une découpe en forme de crochet apte à coiffer une lisse horizontale.
To this end, it relates to a console of the type mentioned above, in particular characterized in that:
  • - the sheath is formed by a jumper, the bottom of which has the cutout,
  • - the rod is provided with a stop member which finds place between the branches of the rider,
  • - the hole in the sheath is positioned in such a way that, instead of hanging by a vertical bar, the console is directly suspended from a rod passing through the cutout in the bottom of the rider, the positioning of this pin passes just under the stop member so that it then prevents both the disengagement of the cutting rod and the rotation of said stop member and,
  • - the branches of the rider each have at their base a hook-shaped cutout capable of covering a horizontal rail.

Elle a également pour objet les dispositifs de sécurité incluant de telles consoles.It also relates to the devices for security including such consoles.

L'invention sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente schématiquement :

  • - figure 1 : la console vue en perspective avec en traits mixtes les trois pièces de fixation,
  • - figure 2 : une coupe par l'axe de la traverse supérieure de la console dans le cas où la fixation s'opère sur une lisse,
  • - figure 3 : une coupe par l'axe de la traverse supérieure de la console dans le cas où la fixation s'opère par appui dans le chéneau,
  • - figure 4 : une coupe par l'axe du fourreau à la base de la console,
  • - figure 5 : une coupe par l'axe de la traverse supérieure de la console dans le cas où l'appui dans le fond du chéneau s'opère à un niveau nettement plus élevé que celui de la traverse supérieure et par exemple en vue de contourner un acrotère ou une corniche.
The invention will be clearly understood with the aid of the description below, given by way of nonlimiting example, with reference to the attached drawing which schematically represents:
  • - Figure 1: the console seen in perspective with dashed lines the three fixing parts,
  • - Figure 2: a section through the axis of the upper cross member of the console in the case where the fixing is effected on a rail,
  • - Figure 3: a section through the axis of the upper cross member of the console in the case where the fixing is effected by pressing in the gutter,
  • - Figure 4: a section through the axis of the sheath at the base of the console,
  • - Figure 5: a section through the axis of the upper cross member of the console in the case where the support in the bottom of the gutter operates at a level significantly higher than that of the upper cross member and for example for bypass an acroterion or a ledge.

En se reportant au dessin, on voit que, à la manière d'une console suspendue à une tige ou à une lisse, chaque console 1, 1' comprend un montant vertical 2 perpendiculairement à la base duquel est soudé un fourreau 3.Referring to the drawing, it can be seen that, like a console suspended from a rod or a heddle, each console 1, 1 ′ comprises a vertical upright 2 perpendicular to the base of which a sheath 3 is welded.

Ce fourreau guide en translation une traverse 4 terminée par une chape 5 appelée par exemple à recevoir une cale 6 d'appui sur un mur 7.This sheath guides in translation a crosspiece 4 terminated by a yoke 5 called for example to receive a wedge 6 for bearing on a wall 7.

La distance entre la chape 5 et le montant 2 est réglée par coulissement de la traverse 4 dans le fourreau 3 dans lequel elle est ensuite immobilisée par une goupille 8 traversant un perçage 9 du fourreau 3 et l'un des perçages 10 de la traverse 4.The distance between the yoke 5 and the upright 2 is adjusted by sliding the cross member 4 in the sleeve 3 in which it is then immobilized by a pin 8 passing through a bore 9 of the sleeve 3 and one of the holes 10 of the cross member 4 .

A la partie supérieure du montant 2 est fixée par l'une de ses extrémités 11 une traverse horizontale 12 dont l'autre extrémité est supportée par une contrefiche 14 prennant elle-même appui à la base du montant 2 et ce directement ou par l'intermédiaire du fourreau 3 de la traverse inférieure 4.At the upper part of the upright 2 is fixed by one of its ends 11 a horizontal crosspiece 12 the other end of which is supported by a strut 14 which itself takes support at the base of the upright 2 and this directly or by the intermediate of the sleeve 3 of the lower cross member 4.

Les traverses supérieures 12 d'au moins deux consoles permettent alors d'établir un plancher 15 et/ou de fixer par tout moyen connu les pieds (non représentés) d'un garde-corps ou d'un filet de protection.The upper crosspieces 12 of at least two consoles then make it possible to establish a floor 15 and / or to fix by any known means the feet (not shown) of a guardrail or a protective net.

D'un côté où la traverse inférieure 4 porte la chape, la partie supérieure du montant 2 porte, et ce directement ou par l'intermédiaire de la dite traverse supérieure 12, un cavalier 16 dont le fond 17 présente une découpe 18 telle un perçage ou une lumière en « U » inverse de largeur légèrement supérieure au diamètre de la tige 19 laquelle est ancrée dans le mur et pourvue d'un organe d'arrêt 20 tel un écrou qui trouve place entre les branches 21, 22 du cavalier qui réalise avec la face avant 23 de la pièce 12 sur laquelle il est fixé un fourreau 24 d'axe vertical, et donc parallèle au montant 2.On one side where the lower cross member 4 carries the yoke, the upper part of the upright 2 carries, either directly or through said upper cross member 12, a jumper 16 whose bottom 17 has a cutout 18 such as a bore or a reverse “U” light of width slightly greater than the diameter of the rod 19 which is anchored in the wall and provided with a stop member 20 such as a nut which finds place between the branches 21, 22 of the rider who realizes with the front face 23 of the part 12 on which a sleeve 24 of vertical axis is fixed, and therefore parallel to the upright 2.

Ce fourreau 24 peut alors recevoir et guider en translation verticale une barre verticale dite « rehausse 25 terminée à sa partie supérieure par une plaque (non représentée) présentant une découpe semblable à celle 18 du fond 17 du cavalier 16.This sheath 24 can then receive and guide in vertical translation a vertical bar known as “enhancer 25 terminated at its upper part by a plate (not shown) having a cutout similar to that of the bottom 17 of the jumper 16.

Une goupille horizontale 26 d'axe parallèle au mur, traverse alors un perçage 27 des branches 21, 22 du cavalier ainsi que l'un des perçages 28 de la rehausse pour l'immobiliser en translation par rapport au fourreau 24 lorsque sa position est correcte.A horizontal pin 26 with an axis parallel to the wall, then crosses a bore 27 of the branches 21, 22 of the rider as well as one of the holes 28 of the riser to immobilize it in translation relative to the sheath 24 when its position is correct .

Le perçage 27 exécuté dans le cavalier pour recevoir cette goupille 26 est positionné de manière telle que, lorsqu'au lieu d'une suspension par une rehausse, la console est directement suspendue à une tige passant dans la découpe 18 du fond du cavalier, la mise en place de cette goupille la fait passer juste sous l'organe d'arrêt 20 tel un écrou, de sorte qu'elle empêche alors à la fois le dégagement de la tige de la découpe et la rotation du dit organe d'arrêt 20. Selon une caractéristique de l'invention, les branches 21, 22 du cavalier 16 présentent chacune, à leur base, une découpe 29 sensiblement en demi cercle leur conférant une forme en crochet apte à coiffer une lisse horizontale 30 suspendue par des pattes (non représentées) elles-mêmes fixées par vissage sur des points d'ancrage prévus dans le mur.The hole 27 executed in the rider to receive this pin 26 is positioned in such a way that, when instead of a suspension by a riser, the console is directly suspended from a rod passing through the cutout 18 in the bottom of the rider, the placement of this pin makes it pass just under the stop member 20 such as a nut, so that it then prevents both the disengagement of the cutting rod and the rotation of said stop member 20 According to a characteristic of the invention, the branches 21, 22 of the rider 16 each have, at their base, a cutout 29 substantially in a semicircle giving them a hook shape capable of covering a horizontal rail 30 suspended by legs (not shown) themselves fixed by screwing on anchor points provided in the wall.

Le bord inférieur 31 du fond 17 du cavalier 16 descend de préférence jusqu'en bas de la lisse pour former une large butée.The lower edge 31 of the bottom 17 of the jumper 16 preferably descends to the bottom of the heddle to form a large stop.

Pour empêcher qu'à la faveur de secousses, la console se dégage de la lisse, selon une autre caractéristique de l'invention, le cavalier porte un verrou 32.To prevent the console from disengaging from the heddle by shaking, according to another characteristic of the invention, the rider carries a lock 32.

Ce verrou est constitué d'une plaque 33 appliquée contre la face externe d'au moins l'une des branches du cavalier et présentant à sa base une lumière en « C » 34 ouverte à l'avant pour que sa branche inférieure 35 s'engage sous la lisse 30. Ce verrou s'articule à sa partie supérieure autour d'un axe 26.This lock consists of a plate 33 applied against the external face of at least one of the arms of the rider and having at its base a "C" light 34 open at the front so that its lower arm 35 s' engages under the heald 30. This lock is articulated at its upper part around an axis 26.

De préférence, le verrou 32 comprend, appliquées chacune contre la face externe de l'une des branches, deux plaques 33 du type ci-dessus et ces plaques sont reliées entre elles par une traverse 36 disposée de manière telle que, lorsque le verrou retient la lisse, la traverse 36 est en appui sur le plancher 15 pour empêcher son soulèvement.Preferably, the latch 32 comprises, each applied against the external face of one of the branches, two plates 33 of the above type and these plates are interconnected by a crosspiece 36 arranged in such a way that, when the latch retains the rail, the crosspiece 36 is supported on the floor 15 to prevent its lifting.

Selon une autre caractéristique de l'invention, par rapport au plan vertical contenant le centre de gravité 37 du verrou 32, l'axe 26 du verrou est déporté vers le fond du cavalier de sorte que, par la pesanteur, le cavalier tende automatiquement à se placer en position de verrouillage.According to another characteristic of the invention, relative to the vertical plane containing the center of gravity 37 of the latch 32, the axis 26 of the latch is offset towards the bottom of the rider so that, by gravity, the rider automatically tends to move to the locked position.

Le bord inférieur 38 se raccorde au nez 39 de la branche inférieure 35 du verrou 32 par un large chanfrein 40 réalisant une rampe dégageant automatiquement le verrou 32 lors de son appui sur la lisse 30.The lower edge 38 is connected to the nose 39 of the lower branch 35 of the latch 32 by a wide chamfer 40 making a ramp which automatically releases the latch 32 when it is pressed on the heddle 30.

Selon une autre caractéristique de l'invention, l'axe du verrou est constitué par la goupille 26 traversant le même perçage 27 des branches 21, 22 du cavalier que pour immobiliser la rehausse 21 ou l'écrou 20 de la tige 19.According to another characteristic of the invention, the axis of the bolt is constituted by the pin 26 passing through the same bore 27 of the arms 21, 22 of the rider as for immobilizing the extension 21 or the nut 20 of the rod 19.

Selon une caractéristique de l'invention, d'une part, l'extrémité avant 23 de la traverse supérieure 12 de la console est ouverte et, d'autre part, le cavalier 17 présente dans le prolongement fictif vers l'avant de la section interne de la traverse supérieure, un dégagement 41 au moins suffisamment important pour laisser libre le susdit prolongement fictif vers l'avant de la section interne de la traverse supérieure, qui, de ce fait, est apte à abriter une coulisse 42 qui pourra venir en saillie à l'avant de la console et être immobilisée en position convenable par une goupille 43 traversant un perçage 44 de la traverse et l'un des perçage 45 de la coulisse.According to a characteristic of the invention, on the one hand, the front end 23 of the upper cross member 12 of the console is open and, on the other hand, the jumper 17 present in the fictitious extension towards the front of the internal section of the upper cross-member, a clearance 41 at least large enough to leave free the aforementioned fictitious extension towards the front of the internal section of the upper cross-member, which is therefore able to house a slide 42 which may protrude from the front of the console and be immobilized in a suitable position by a pin 43 passing through a hole 44 in the cross member and one of the holes 45 in the slide.

Cette coulisse pourra par exemple porter à son extrémité avant un fourreau 46 parallèle au montant et logeant un poinçon 47 terminé à sa base (non représenté) par une chape pourvue d'un patin d'appui dans un chéneau.This slide may for example carry at its front end a sheath 46 parallel to the upright and housing a punch 47 terminated at its base (not shown) by a yoke provided with a support pad in a gutter.

Dans le cas où le chéneau se situe à un niveau nettement supérieur ou lorsqu'il est nécessaire de contourner un acrotère ou une corniche, l'ensemble formé par le fourreau 46 et le poinçon 47 pourra, par sa coulisse 42, être porté par un fourreau (non représenté) porté en tête d'une barre verticale dite « faux-montant 48 qui, à la manière de la rehausse 25, est engagée et immobilisée en translation dans le cavalier 17 qui, dans le cas correspondant, est libre de toute rehausse.In the case where the gutter is located at a clearly higher level or when it is necessary to bypass an acroterion or a cornice, the assembly formed by the sheath 46 and the punch 47 may, by its slide 42, be carried by a sheath (not shown) carried at the head of a vertical bar known as a "false upright 48 which, like the extension 25, is engaged and immobilized in translation in the rider 17 which, in the corresponding case, is free from any enhances.

Dans ce cas, dans un mode préféré, le faux montant est également verrouillé dans la chape 5 de la traverse inférieure 4 de la console, à l'aide d'une goupille 49 traversant un perçage 50 de la chape et l'un des perçages 51 du faux montant 48.In this case, in a preferred mode, the false upright is also locked in the yoke 5 of the lower cross member 4 of the console, using a pin 49 passing through a hole 50 in the yoke and one of the holes 51 of the false amount 48.

De préférence, la chape 5 est dimensionnée de manière telle que la rangée des perçages 50 puisse être alignée avec celle des perçages 28 recevant la goupille 26.Preferably, the yoke 5 is dimensioned in such a way that the row of holes 50 can be aligned with that of the holes 28 receiving the pin 26.

L'appui au mur se fait alors quant à lui par un ensemble (non représenté) fourreau et traverse avec patin du type de ceux 3, 4, 5 et 6 décrits plus haut, mais portés par le faux montant 48.The support on the wall is then made by a set (not shown) of the sleeve and crosses with shoe of the type of those 3, 4, 5 and 6 described above, but carried by the false upright 48.

Ainsi réalisée, une même console peut donc coopérer avec des moyens de fixation en relation avec des barres ou traverses selon trois axes X, Y et Z perpendiculaires entre eux.Thus produced, the same console can therefore cooperate with fixing means in relation to bars or crosspieces along three axes X, Y and Z perpendicular to each other.

En plus des trois possibilités de fixation évoquées plus haut, lorsqu'elles sont en appui direct dans le chéneau ou suspendues à des tiges perpendiculaires au mur et engagées dans les découpes du cavalier, ces consoles permettent d'utiliser la découpe 29 et le verrou 32 de blocage de la lisse pour bloquer un tube d'entretoisement des consoles et/ou en vue d'établir un plancher en porte à faux.In addition to the three fixing possibilities mentioned above, when they are in direct support in the gutter or suspended on rods perpendicular to the wall and engaged in the rider's cutouts, these consoles allow the cutout 29 and the lock 32 to be used beam blocking device to block a bracing tube for the consoles and / or to establish a cantilevered floor.
