Abstract

The grating is made from a series of separate bars (1) which are assembled in parallel by a rod (2) which passes through each bar and spacers (4) between them. Each bar has two parallel projections (6) on each side pointing in the direction of the neighbouring bar and covering the upper and lower surfaces of the spacers, which are made from a suitable synthetic material such as neoprene and are circular in shape. The bars have T-shaped ends (8), the rod joining them together being made from a comparatively flexible material, so that the grating formed from the bars can follow a curved shape if necessary.

Description

La présente invention a essentiellement pour objet une grille modulaire pour l'obturation des regards de chaussée et tout particulièrement des caniveaux.The main subject of the present invention is a modular grid for closing the manholes of pavement and especially gutters.

Il est connu depuis longtemps d'obturer les regards sur une chaussée par exemple au moyen de grilles généralement supportées par des cadres noyés dans la chaussée. Ces grilles se composent généralement d'une pluralité de barreaux assemblés sensiblement parallèlement (voir p.ex. GB-A-2 099 893).It's been known for a long time to shut the eyes on a pavement for example by means of grids generally supported by frames embedded in the pavement. These grids generally consist of a plurality of bars assembled substantially parallel (see eg GB-A-2 099 893).

Dès lors, les diverses dimensions et formes de regard exigent l'utilisation d'autant de formes et dimensions de grilles, ce qui complique les fabrications et rend lesdites grilles coûteuses.Consequently, the various dimensions and forms of gaze require the use of as many shapes and dimensions of grids, which complicates manufacturing and makes said costly grids.

La présente invention a donc pour but de remédier notamment à ces inconvénients en proposant une grille modulaire et en quelque sorte universelle qui peut aisément s'adapter à toute forme ou dimension de regard et qui peut facilement s'adapter à tout type de caniveau rectiligne ou même sinueux dans un plan horizontal ou s'écartant du plan horizontal.The present invention therefore aims to remedy particularly to these drawbacks by proposing a grid modular and somehow universal which can easily adapt to any shape or dimension of gaze and which can easily adapt to any type of channel straight or even sinuous in a horizontal plane or deviating from the horizontal plane.

A cet effet, l'invention a pour objet une grille modulaire pour l'obturation de caniveaux par exemple et se composant d'une pluralité de barreaux assemblés sensiblement parallèlement; lesdits barreaux sont indépendants les uns des autres et sont assemblés par une tige ou analogue traversant tous les barreaux et des entretoises interposées entre lesdits barreaux.To this end, the invention relates to a grid modular for closing gutters for example and consisting of a plurality of assembled bars substantially parallel; said bars are independent of each other and are assembled by a rod or the like passing through all bars and spacers interposed between said bars.

On comprend donc déjà qu'il sera aisé de supprimer ou d'ajouter des barreaux pour permettre l'adaptation de la grille à un regard de dimensions données. We therefore already understand that it will be easy to delete or add bars to allow the adaptation of the grid to a look of given dimensions.

Selon une autre caractéristique de cette grille, chaque barreau comporte des saillies s'étendant en direction des barreaux adjacents de façon à maintenir en la recouvrant, l'entretoise entre deux barreaux adjacents.According to another characteristic of this grid, each bar has projections extending towards the adjacent bars so as to maintain by covering it, the spacer between two adjacent bars.

Les entretoises, suivant un mode de réalisation préféré, sont en une matière synthétique appropriée, telle que néoprène par exemple, et elles peuvent présenter une forme circulaire.The spacers, according to a preferred embodiment, are made of a suitable synthetic material, such as neoprene for example, and they can have a circular shape.

Ainsi, grâce à la présence des entretoises, on pourra avantageusement déformer la grille pour qu'elle s'adapte à la forme quelque peu courbe ou en dévers du regard ou du caniveau.Thus, thanks to the presence of the spacers, we can advantageously deform the grid so that it fits with a slightly curved or sloping shape of the look or of the gutter.

Suivant encore une autre caractéristique de la grille selon cette invention, les entretoises, les saillies sur chaque barreau et les trous dans les barreaux permettant le passage de la tige assurant l'assemblage desdits barreaux, sont prévus à une distance sensiblement égale des extrémités libres des barreaux.According to yet another characteristic of the grid according to this invention, the spacers, the projections on each bar and the holes in the bars allowing the passage of the rod ensuring the assembly of said bars, are provided at a substantially equal distance free ends of the bars.

On précisera encore ici que chaque barreau comporte des saillies parallèles prenant naissance en partie supérieure et en partie inférieure de l'âme du barreau.We will also specify here that each bar has parallel projections partly arising upper and lower part of the core of the bar.

Les extrémités libres des barreaux comportent un renflement ou analogue, leur conférant une forme de T.The free ends of the bars have a bulge or the like, giving them a T shape.

Mais d'autres caractéristiques et avantages de l'invention apparaítront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels.But other features and advantages of the invention will appear better in the description detailed which follows and refers to the attached drawings, given only by way of example, and in which.

La figure 1 est une vue partielle et en plan de dessus d'une grille conforme aux principes de l'invention. Figure 1 is a partial plan view from above a grid in accordance with the principles of the invention.

La figure 2 est une vue de côté, suivant la flèche II de la figure 1.Figure 2 is a side view, along arrow II of Figure 1.

La figure 3 est une vue en perspective d'un barreau de la grille.Figure 3 is a perspective view of a bar of the wire rack.

La figure 4 est une vue en plan de dessus de la grille illustrée en position déformée pour pouvoir s'adapter à un regard ou une portion de caniveau de forme courbe.Figure 4 is a top plan view of the grid illustrated in deformed position to be able to adapt to a look or a portion of a curved gutter.

Suivant un exemple de réalisation, et en se reportant aux dessins, on voit qu'une grille conforme à cette invention se compose d'une pluralité de barreaux 1 qui sont, structurellement parlant, indépendants les uns des autres et qui peuvent être assemblés par une tige ou analogue repérée en 2 et qui peut être par exemple une tige filetée plus ou moins flexible.According to an exemplary embodiment, and with reference to drawings, we see that a grid according to this invention consists of a plurality of bars 1 which are, structurally speaking, independent of each other and which can be assembled by a rod or the like marked in 2 and which can be for example a rod more or less flexible threaded.

Cette tige 2 traverse des orifices 3 ménagés dans chaque barreau 1 et permet par conséquent l'assemblage d'un nombre quelconque de barreaux, étant entendu qu'un boulon par exemple (non représenté) vissé aux deux extrémités de la tige permettra l'assemblage.This rod 2 passes through orifices 3 formed in each bar 1 and therefore allows the assembly of a any number of bars, it being understood that a bolt for example (not shown) screwed at the two ends of the rod will allow assembly.

Bien que cela ne soit nullement obligatoire, mais suivant un mode de réalisation préféré, une entretoise 4 percée d'un trou 5 est interposée entre deux barreaux adjacents 1, de sorte que la tige 2 traversera tous les barreaux 1 et toutes les entretoises 4.Although this is by no means mandatory, but following a preferred embodiment, a pierced spacer 4 of a hole 5 is interposed between two adjacent bars 1, so that the rod 2 will pass through all the bars 1 and all spacers 4.

Les entretoises 4 peuvent être en une matière synthétique appropriée quelconque telle que le néoprène.The spacers 4 can be made of a synthetic material any suitable such as neoprene.

Suivant l'exemple représenté, les entretoises présentent une forme circulaire, comme on le voit bien sur la figure 2, mais elles pourraient parfaitement présenter toute autre forme sans sortir du cadre de l'invention.According to the example shown, the spacers have a circular shape, as can be seen in the figure 2, but they could perfectly present any other form without departing from the scope of the invention.

On a montré en 6 et 7 des saillies venant de moulage avec chaque barreau 1 et s'étendant en direction des barreaux adjacents. Plus précisément, comme on le voit bien sur les figures 1, 2 et 3, les saillies 6 et 7 permettent le maintien d'une entretoise 4 entre deux barreaux adjacents 1, les saillies 6 prenant naissance en partie supérieure de l'âme du barreau, et les saillies 7 prenant naissance en partie inférieure de ladite âme.We have shown in 6 and 7 protrusions coming from molding with each bar 1 and extending in the direction of the bars adjacent. More precisely, as we can see on Figures 1, 2 and 3, the projections 6 and 7 allow the maintenance of a spacer 4 between two adjacent bars 1, the projections 6 originating at the top of the soul of the bar, and the projections 7 arising in the lower part of said core.

Les saillies 6 et 7 s'étendent sensiblement parallèlement l'une à l'autre, comme on le voit bien sur la figure 3, et elles recouvrent sensiblement complètement l'entretoise 4 entre deux barreaux adjacents. Ainsi, les saillies 6 assureront en quelque sorte une continuité de la grille en partie supérieure et protégeront les entretoises sous-jacentes 4.The projections 6 and 7 extend substantially parallel to each other, as can be seen in Figure 3, and they cover substantially completely the spacer 4 between two adjacent bars. So the protrusions 6 will somehow ensure continuity of the grille in the upper part and will protect underlying spacers 4.

Dans l'exemple illustré, les saillies 6, 7, les entretoises 4 et les trous 3 dans chaque barreau 1 sont prévus à une distance sensiblement égale des extrémités libres des barreaux.In the example illustrated, the projections 6, 7, the spacers 4 and the holes 3 in each bar 1 are provided at a substantially equal distance from the ends free from bars.

Mais tous ces éléments pourraient être situés de façon plus rapprochée de l'une ou l'autre des extrémités libres des barreaux 1, sans pour cela sortir du cadre de l'invention.But all of these could be located so closer to one or other of the free ends bars 1, without departing from the scope of the invention.

Les extrémités libres des barreaux 1 comportent, suivant l'exemple représenté, un renflement 8 qui confère à ces extrémités libres, une forme de T, de façon que les deux côtés opposés de la grille comportant les renflements 8 forment une solution de continuité. The free ends of the bars 1 comprise, according to the example shown, a bulge 8 which gives these free ends, a T shape, so that both opposite sides of the grid with the bulges 8 form a solution of continuity.

On comprend donc de la description qui précède que la grille selon cette invention est particulièrement avantageuse au regard des points suivants.It is therefore understood from the above description that the grid according to this invention is particularly advantageous with regard to the following points.

La suppression ou l'adjonction d'un ou plusieurs barreaux 1 permettra à la grille de s'adapter à des dimensions diverses de regard, qu'il s'agisse d'un trou ou d'un caniveau de forme rectangulaire.The removal or addition of one or more bars 1 will allow the grid to adapt to dimensions various look, whether it is a hole or a rectangular channel.

De plus, les barreaux 1 de la grille étant manoeuvrables l'un par rapport à l'autre autour de l'axe constitué par la tige 2, il sera permis à la grille de suivre un dévers éventuel des bords du caniveau.In addition, the bars 1 of the grid being maneuverable one with respect to the other around the axis constituted by rod 2, the grid will be allowed to follow a superelevation any edges of the gutter.

Grâce à la flexibilité relative de la tige 2, il sera aussi possible de conférer à la grille une forme légèrement courbe, comme on le voit sur la figure 4, pour que la grille puisse se conformer à la sinuosité du caniveau.Thanks to the relative flexibility of the rod 2, it will also possible to give the grid a shape slightly curved, as seen in Figure 4, for that the grid can conform to the winding of the gutter.

En bref, le fait que les barreaux 1 soient indépendamment manoeuvrables, et le fait que lesdits barreaux puissent s'écarter de leur position strictement parallèle grâce à la flexibilité de la tige 2 et des entretoises 4, permettront à la grille de s'adapter à une grande variété de formes et dimensions de regard ou de caniveau. In short, the fact that the bars 1 are independently maneuverable, and the fact that said bars can deviate from their strictly parallel position thanks to the flexibility of the rod 2 and the spacers 4, allow the grid to adapt to a wide variety of shapes and dimensions of manhole or gutter.

Bien entendu, la grille de cette invention peut être logée et maintenue dans un cadre noyé dans la chaussée, sur le pourtour du regard à obturer.Of course, the grid of this invention can be accommodated and kept in a frame buried in the pavement, on the around the manhole to close.
