Description

L'invention concerne une console de type repliable pour des dispositifs de sécurité, et notamment pour des passerelles des garde-corps, filets de protection, que l'on veut fixer à une construction pour en faciliter la poursuite de la réalisation, l'entretien ou la réparation.The invention relates to a foldable type console for safety devices, and in particular for walkways of guardrails, protective nets, which are to be fixed to a construction in order to facilitate further construction and maintenance. or repair.

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

Sans que cela soit limitatif, elle vise plus spécialement les consoles repliables pour dispositifs en vue du travail sur les versants des toits pour lesquelles le repliage leur permet de s'adapter à l'inclinaison propre à chaque toit.Without being limiting, it is more particularly aimed at the folding consoles for devices for working on the slopes of roofs for which the folding allows them to adapt to the inclination proper to each roof.

Dans tous les cas, ces consoles sont formées d'une traverse principale horizontale, d'une part, présentant à l'une de ses extrémités des moyens de fixation à la pièce d'ancrage portée par la paroi et, d'autre part, sous laquelle, par l'une de ses extrémités est articulé autour d'un axe orthogonal à la traverse un bras dont l'extrémité porte un moyen d'appui à la paroi, l'angle A entre la traverse et le bras étant déterminé par une entretoise articulée à l'une de ses extrémités sur une patte du bras et associé par ailleurs à la traverse par une broche traversant un orifice de la traverse et l'un des logements de l'entretoise.In all cases, these brackets are formed of a horizontal main cross member, on the one hand, having at one of its ends means for fixing to the anchoring piece carried by the wall and, on the other hand, under which, by one of its ends is articulated around an axis orthogonal to the cross-member an arm whose end carries a means of bearing on the wall, the angle A between the cross-member and the arm being determined by a spacer articulated at one of its ends on a leg of the arm and associated moreover with the cross-member by a pin passing through an orifice of the cross-member and one of the housings of the spacer.

On remarque que de telles consoles sont démontables et repliables après retrait de la broche ce qui permet de réduire leur encombrement mais cette opératon de repliage, d'une part, prend du temps car elle nécessite le démontage préalable du moyen d'appui à la paroi pour que, par l'articulation autour de l'axe de la patte, l'entretoise puisse ensuite être rabattue sous le bras et la traverse et, d'autre part, conduit à un ensemble articulé difficile à tenir en place.It is noted that such consoles are removable and foldable after removal of the spindle which makes it possible to reduce their bulk, but this folding operation, on the one hand, takes time because it requires the prior dismantling of the support means to the wall. so that, by the articulation around the axis of the lug, the spacer can then be folded under the arm and crosses it and, on the other hand, leads to an articulated assembly difficult to hold in place.

Un des buts de la présente invention est de remédier à ces inconvénients et de proposer une console pour dispositifs de sécurité qui soit repliable aisément sans démontage d'éléments et qui offre en position repliée un encombrement tout à fait réduit et un maintien groupé des éléments qui la constituent.One of the aims of the present invention is to remedy these drawbacks and to propose a console for safety devices which is easily foldable without dismantling of elements and which offers in the folded position a quite reduced bulk and a grouped holding of the elements which constitute it.

D'autres buts et avantages de la présente invention apparaitront au cours de la description qui va suivre, qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de limiter l'invention.Other objects and advantages of the present invention will appear during the description which follows, which is however only given for information and which is not intended to limit the invention.

A cet effet, elle a pour objet une console de type repliable du type précité notamment caractérisée en ce que :

  • - d'une part, le bras présente entre ses axes d'articulation à la traverse et à l'entretoise une longueur qui est supérieure à la distance mesurée sur la traverse entre ses axes d'articulation au bras et à l'entretoise d'une valeur au moins suffisante pour que la patte associée au bras passe librement au delà de l'extrémité de la traverse lors de la fermeture de l'angle et,
  • - d'autre part, la hauteur à laquelle la patte place par rapport au bras l'axe de l'entretoise est au moins suffisante pour qu'après fermeture de l'angle, l'entretoise puisse, par articulaton autour de cet axe, venir se rabattre au dessus de la traverse.
To this end, it relates to a folding type console of the aforementioned type, in particular characterized in that:
  • - On the one hand, the arm has between its axes of articulation to the cross member and the spacer a length which is greater than the distance measured on the cross member between its axes of articulation to the arm and to the spacer a value at least sufficient for the tab associated with the arm to pass freely beyond the end of the cross-member when the angle is closed and,
  • - on the other hand, the height at which the tab places with respect to the arm the axis of the spacer is at least sufficient so that after closing the angle, the spacer can, by articulation around this axis, come and fold over the cross.

Elle a également pour objet le dispositif de sécurité incluant de telles consoles.It also relates to the safety device including such consoles.

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

  • - figure 1: une console dépliée et fixée à titre d'exemple sur une paroi inclinée,
  • - figures 2 et 3: la console de la figure 1 dans différentes phases intermédiaires de son repliage,
  • - figure 4: la console en position repliée.
The invention will be better 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: an unfolded console and fixed by way of example on an inclined wall,
  • - Figures 2 and 3: the console of Figure 1 in different intermediate phases of its folding,
  • - Figure 4: the console in the folded position.

Dans la figure 1, on a représenté, à titre d'exemple non limitatif, une console 1 fixée à une paroi inclinée 2, par des moyens d'ancrage connus tels par exemple une lisse 3.In FIG. 1, there is shown, by way of nonlimiting example, a console 1 fixed to an inclined wall 2, by known anchoring means such for example as a heddle 3.

La paroi 2 est par exemple le versant d'une toiture, cependant, tel que cela apparaîtra plus loin, la console 1 peut également être fixée sur une paroi verticale et, par exemple, un mur de façade.The wall 2 is for example the slope of a roof, however, as will appear later, the console 1 can also be fixed on a vertical wall and, for example, a facade wall.

La console 1 comprend une traverse principale 4 qui, en position de travail, se trouve généralement approximativement horizontale et présente une surface supérieure apte à recevoir différents équipements, et notamment des planches en vue de constituer une passerelle.The console 1 comprises a main crossmember 4 which, in the working position, is generally approximately horizontal and has an upper surface capable of receiving various equipment, and in particular planks with a view to constituting a gangway.

La traverse 4 présente à l'une (5) de ses extrémités 5, 6 des moyens 7 de fixation à la pièce d'ancrage 3, tels par exemple une pince auto-verrouillante du type de celle qui est décrite dans le brevet FR-83.18153.The crosspiece 4 has at one (5) of its ends 5, 6 means 7 for fixing to the anchor 3, such as for example a self-locking clamp of the type described in the patent FR- 83.18153.

Dans le cas d'une console pour travaux sur versants de toit, de préférence, les moyens 7 de fixation de la traverse 4 à la paroi 2 autorisent une articulation de la console autour d'un axe horizontal et parallèle à la paroi 2.In the case of a console for work on roof slopes, preferably, the means 7 for fixing the cross-member 4 to the wall 2 allow the console to be articulated about a horizontal axis and parallel to the wall 2.

Sous la traverse 4, par l'une (9) de ses extrémités 9, 10, un bras 11 est articulé autour d'un axe 12 orthogonal à l'axe longitudinal 13 de la traverse 4.Under the cross-member 4, through one (9) of its ends 9, 10, an arm 11 is articulated around an axis 12 orthogonal to the longitudinal axis 13 of the cross-member 4.

Le bras articulé 11 porte à son autre extrémité 10 un moyen 14 d'appui sur la paroi 2 tel un patin relié au bras 11 par un axe 15 parallèle à l'axe 12 d'articulation du bras 11 sur la traverse 4.The articulated arm 11 carries at its other end 10 a means 14 for bearing on the wall 2 such as a shoe connected to the arm 11 by an axis 15 parallel to the axis 12 of articulation of the arm 11 on the crosspiece 4.

Naturellement, le patin 14 pourrait être remplacé par tout autre moyen approprié.Naturally, the shoe 14 could be replaced by any other appropriate means.

Une entretoise 16 détermine l'écartement angulaire entre la traverse 4 et le bras 11.A spacer 16 determines the angular spacing between the cross-member 4 and the arm 11.

A cet effet, elle est fixée entre les extrémités 6, 10 des branches de l'angle A que forment les traverses 4 et le bras 11 par rapport auxquelles extrémités elle est fixée par des axes 17, 18 parallèles à l'axe d'articulation du bras 11 sur la traverse 4.For this purpose, it is fixed between the ends 6, 10 of the branches of the angle A formed by the crosspieces 4 and the arm 11 with respect to which ends it is fixed by axes 17, 18 parallel to the axis of articulation. of arm 11 on the cross 4.

Au niveau de l'extrémité 6 de la traverse 4, l'entretoise 16 offre à cet axe amovible plusieurs logements 19 qui permettent de régler l'écartement entre les extrémités 6, 10 de la traverse 4 et du bras et ainsi de régler l'inclinaison de la traverse 4.At the end 6 of the cross-member 4, the spacer 16 offers several removable housings 19 on this removable axis 19 which make it possible to adjust the spacing between the ends 6, 10 of the cross-member 4 and of the arm and thus to adjust the inclination of the cross 4.

Au niveau de l'extrémité 10 du bras, l'entretoise est reliée par au moins une patte 20 portant l'axe 17 permettant l'articulation de l'entretoise 16 sur le bras 11.At the end 10 of the arm, the spacer is connected by at least one tab 20 carrying the axis 17 allowing the articulation of the spacer 16 on the arm 11.

Selon une caractéristique de l'invention :

  • - d'une part, le bras 11 présente entre ses axes 12, 17 d'articulation à la traverse 4 et à l'entretoise 16, une longueur L qui est supérieure à la distance D mesurée sur la traverse 4 entre ses axes d'articulation 12, 18 au bras et à l'entretoise d'une valeur V au moins suffisante pour que la patte 20 associée au bras passe librement au delà de l'extrémité de la traverse lors de la fermeture de l'angle A et,
  • - d'autre part, la hauteur H à laquelle la patte 20 place par rapport au bras 11 l'axe 17 de l'entretoise est au moins suffisante pour qu'après fermeture de l'angle A l'entretoise puisse, par articulation autour de cet axe 17, venir se rabattre au dessus de la traverse 4.
According to a characteristic of the invention:
  • - On the one hand, the arm 11 has between its axes 12, 17 of articulation to the cross member 4 and to the spacer 16, a length L which is greater than the distance D measured on the cross member 4 between its axes of articulation 12, 18 to the arm and to the spacer of a value V at least sufficient for the tab 20 associated with the arm to pass freely beyond the end of the cross-member when the angle A is closed and,
  • - on the other hand, the height H at which the tab 20 places relative to the arm 11 the axis 17 of the spacer is at least sufficient so that after closing the angle A the spacer can, by articulation around of this axis 17, come to fold over the cross 4.

Ainsi, tel que cela est visible en figure 3, l'axe d'articulation 17 se situe au dessus du niveau supérieur de la traverse 4 et, en particulier, du fourreau 8 ; c'est ce qui rend possible le rabattement du montant 11 contre la traverse 4 ainsi que le schématise la flèche 21.Thus, as shown in Figure 3, the hinge pin 17 is located above the upper level of the cross 4 and, in particular, of the sleeve 8; this is what makes it possible to fold the upright 11 against the cross-member 4 as shown by the arrow 21.

Dans un mode préféré de réalisation, la longueur de l'entretoise 16 est telle qu'après fermeture de l'angle A et rabattement sur la traverse de la dite entretoise 16, celle-ci a son extrémité libre 22 qui vient se loger dans les moyens 7 de fixation de la traverse 4 sur la paroi 2 ainsi que cela est visible en figure 4. Ces moyens 7 de fixation ou plus généralement l'extrémité 6 de la traverse 4, présente des moyens 23, 24 de verrouillage de l'extrémité libre 21 de l'entretoise 16.In a preferred embodiment, the length of the spacer 16 is such that after closing the angle A and folding down on the crosspiece of the said spacer 16, the latter has its free end 22 which is received in the means 7 for fixing the cross-member 4 on the wall 2 as can be seen in FIG. 4. These means 7 for fixing or more generally the end 6 of the cross-member 4 has means 23, 24 for locking the end free 21 of the spacer 16.

Ces moyens de verrouillage consistent par exemple en un orifice 23 des moyens de fixation 7 recevant une broche 24 passant soit au dessus de l'extrémité libre 22 de l'entretoise 16, soit dans l'un de ses logements 19.These locking means consist for example of an orifice 23 of the fixing means 7 receiving a pin 24 passing either above the free end 22 of the spacer 16, or in one of its housings 19.

Il faut remarquer que, compte tenu du mode d'articulation de l'entretoise sur le bras 11, le verrouillage de l'extrémité libre de l'entretoise 16 verrouille l'ensemble de la console 1 en position repliée.It should be noted that, given the mode of articulation of the spacer on the arm 11, the locking of the free end of the spacer 16 locks the assembly of the console 1 in the folded position.

De manière évidente, le dépliage de la console 1 s'effectue en effectuant dans l'ordre inverse la manoeuvre précédemment décrite.Obviously, the unfolding of the console 1 is carried out by carrying out in the reverse order the maneuver previously described.

Il faut souligner que le pliage et le dépliage de la console s'effectuent selon une succession d'opérations naturelles, qui ne nécessitent aucune manoeuvre compliquée des différents éléments. Par ailleurs, en position repliée, la console 1 est immobilisée dans un encombrement minimum et peut donc être facilement stockée, transportée, manipulée par un utilisateur.It should be noted that the folding and unfolding of the console is carried out according to a succession of natural operations, which do not require any complicated operation of the different elements. Furthermore, in the folded position, the console 1 is immobilized in a minimum size and can therefore be easily stored, transported and handled by a user.

En position de travail, la console peut recevoir un plancher, un verrou de plancher, des garde-corps longitudinaux, des garde-corps d'extrémité, ainsi que des rehausses qui permettront des travaux sur les cheminées.In the working position, the console can receive a floor, a floor lock, longitudinal railings, end railings, as well as extensions that will allow work on chimneys.

Naturellement, la présente description n'est donnée qu'à titre indicatif, et l'on pourrait adopter d'autres mises en oeuvre de l'invention sans pour autant sortir du cadre de celle-ci.Naturally, the present description is given for information only, and other implementations of the invention could be adopted without departing from the scope thereof.
