Description

La présente invention concerne de façon générale une pièce de voirie, notamment utilisable comme bouche d'égout.The present invention generally relates to a piece of road, in particular usable as a mouth disgust.

Plus précisément, l'invention concerne une pièce de voirie, du type de celles qui comprennent au moins un bâti et une grille métallique montée pivotante, par un premier bord, sur le bâti, entre une position de fermeture dans laquelle elle couvre une première partie au moins du bâti, et une position d'ouverture, cette grille présentant, sur un second bord opposé au premier, au moins un relief, chaque relief étant porté par un barreau élastique correspondant et sélectivement engagé dans un logement de retenue du bâti pour immobiliser la grille en position de fermeture.More specifically, the invention relates to a piece of roads, of the type that includes at least one frame and a metal grid pivotally mounted, by a first edge, on the frame, between a position of closure in which it covers a first part at least of the frame, and an open position, this grid presenting, on a second edge opposite the first, at least one relief, each relief being carried by a corresponding and selectively engaged elastic bar in a housing retaining housing to immobilize the grid in the closed position.

Des pièces de voirie de ce type sont déjà connues dans l'art antérieur, comme en témoignent par exemple les documents de brevets FR - 2 716 472 et EP - 0 280 872.Road pieces of this type are already known in the prior art, as evidenced, for example, by patent documents FR - 2 716 472 and EP - 0 280 872.

Dans le cas où la pièce de voirie présente une structure plus complexe, et comprend notamment un couvercle pour servir de bouche d'égout, le problème se pose d'assurer de façon simple et au moindre coût le verrouillage de l'ensemble des éléments mobiles par rapport au bâti.In the case where the piece of road has a structure more complex, and includes a cover for serve as a manhole, the problem arises to ensure in a simple way and at the least cost the locking of all the movable elements relative to the frame.

Le but de la présente invention est précisément d'apporter une solution à ce problème.The purpose of the present invention is precisely to provide a solution to this problem.

A cette fin, la pièce de voirie de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisée en ce qu'elle comprend un couvercle monté pivotant, par un premier bord, sur le bâti, entre une position de fermeture dans laquelle il couvre une seconde partie au moins du bâti, et une position d'ouverture, ce couvercle présentant un second bord, opposé à son premier bord et connexe au second bord de la grille en position de fermeture de la grille et du couvercle, en ce que le relief est porté par une extrémité libre du barreau élastique qui est également dotée d'une encoche, et en ce que le couvercle présente sur son second bord un ergot correspondant sélectivement engagé dans l'encoche pour immobiliser le couvercle en position de fermeture sur le bâti par l'intermédiaire de la grille.For this purpose, the road piece of the invention, for otherwise consistent with the generic definition given in the preamble above is essentially characterized in that it comprises a pivotally mounted cover, for a first edge, on the frame, between a position of closure in which it covers a second part at less of the frame, and an open position, this lid having a second edge, opposite to its first edge and connected to the second edge of the grid in position closing of the grid and the lid, in that the relief is carried by a free end of the bar elastic which also has a notch, and in that that the lid has on its second edge a lug correspondent selectively engaged in the notch for immobilize the lid in the closed position on the built through the grid.

Dans le mode de réalisation préféré de l'invention, le relief présente une surface en biseau qui se trouve en regard d'un rebord du logement de retenue pour une position d'approche de fermeture de la grille, et ce relief, à partir de cette position d'approche de fermeture de la grille, s'engage dans le logement de retenue par application sur l'extrémité libre du barreau élastique d'une force orientée suivant une première direction essentiellement perpendiculaire à ce barreau, et dont une composante, résultant d'un contact de la surface en biseau sur le rebord du logement de retenue, opère une déflection du barreau élastique suivant une seconde direction, essentiellement perpendiculaire à la première direction et à ce barreau élastique.In the preferred embodiment of the invention, the relief has a beveled surface that is in look at a rim of the retaining housing for a closing approach position of the grid, and this relief, from this approach position of closing of the grid, engages in the housing of retained by application on the free end of the bar elastic of a force oriented according to a first direction essentially perpendicular to this bar, and of which a component, resulting from a contact of the bevelled surface on the edge of the retaining housing, deflects the elastic bar following a second direction, essentially perpendicular to the first direction and at this elastic bar.

L'ergot et l'encoche présentent par exemple des rampes d'approche respectives en regard l'une de l'autre pour une position d'approche de fermeture du couvercle, de sorte que l'ergot, à partir de la position d'approche de fermeture du couvercle, s'engage dans l'encoche par application sur cet ergot d'une force orientée suivant une troisième direction essentiellement perpendiculaire aux première et seconde directions, et dont une composante, résultant d'un contact mutuel des rampes d'approche de l'ergot et de l'encoche, opère une déflection du barreau élastique suivant une quatrième direction, essentiellement inverse de la seconde direction.The lug and the notch have for example ramps respective approaches to each other for an approach position closing the lid, so that the ergot, from the approach position of closing of the lid, engages in the notch by application on this pin of a force oriented next a third direction essentially perpendicular in the first and second directions, and one of which component, resulting from mutual contact between the approach of the pin and the notch, operates a deflection of the elastic bar after a fourth direction, essentially the opposite of the second direction.

De préférence, l'ergot et l'encoche présentent par ailleurs des rampes de retenue respectives en regard l'une de l'autre pour la position de fermeture du couvercle, et l'ergot, lorsque le couvercle est écarté de sa position de fermeture, se dégage de l'encoche par application, sur cet ergot, d'une force orientée suivant une cinquième direction, essentiellement inverse de la troisième direction, et dont une composante, résultant d'un contact mutuel des rampes de retenue de l'ergot et de l'encoche, opère une déflection du barreau élastique suivant la quatrième direction.Preferably, the lug and the notch present by elsewhere respective retaining ramps each other for the closing position of the lid, and the lug, when the lid is removed from its closing position, emerges from the notch by application, on this pin, of a force oriented next a fifth direction, essentially the reverse of the third direction, and one component of which mutual contact of the ergot retaining ramps and of the notch, operates a deflection of the elastic bar following the fourth direction.

Un interstice est en outre avantageusement prévu entre l'extrémité libre du barreau et le bâti en position de fermeture de la grille, pour permettre à un levier inséré dans cet interstice d'appliquer sur l'extrémité libre du barreau une force orientée suivant la seconde direction provoquant une déflexion du barreau suivant cette seconde direction et dégageant le relief du logement de retenue.A gap is furthermore advantageously provided between the free end of the bar and the frame in position closing the grid, to allow a lever inserted in this gap to apply on the free end of the bar a force oriented in the second direction causing a deflection of the bar following this second direction and clearing the relief of the retaining housing.

D'autres caractéristiques et avantages de l'invention ressortiront clairement de la description qui en est faite ci-après, à titre indicatif et nullement limitatif, en référence aux dessins annexés, dans lesquels :Other features and advantages of the invention will be clear from the description which is below, as an indication and in no way limiting, with reference to the accompanying drawings, in which:

La figure 7 est une vue semblable à la figure 6, mais représentant le barreau élastique et le logement de retenue pour la position d'approche de fermeture de la grille.Figure 7 is a view similar to Figure 6, but representing the elastic bar and housing of retained for the closing approach position of the wire rack.

Comme le montre la figure 1, l'invention concerne une pièce de voirie comprenant essentiellement un bâti 1, une grille métallique 2, et un couvercle 4.As shown in Figure 1, the invention relates to a piece of road comprising essentially a frame 1, a metal grill 2, and a lid 4.

La grille 2 est montée pivotante, par un bord 21, sur un bord correspondant 13 du bâti 1, entre une position de fermeture Z2 dans laquelle elle couvre une première partie P1 du bâti, et une position d'ouverture A2 (figure 1).The grid 2 is pivotally mounted, by an edge 21, on a corresponding edge 13 of the frame 1, between a position of Z2 closure in which it covers a first part P1 of the frame, and an open position A2 (FIG. 1).

Le couvercle 4 est lui-même monté pivotant, par un premier bord 41, sur un autre bord 14 du bâti 1, entre une position de fermeture Z4 dans laquelle il couvre une seconde partie P2 du bâti 1, et une position d'ouverture A4.The lid 4 is itself pivotally mounted, by a first edge 41, on another edge 14 of the frame 1, between a closed position Z4 in which it covers a second part P2 of the frame 1, and an open position A4.

Comme le montre la figure 1, les bords internes respectifs 22 et 42 de la grille et du couvercle, qui sont opposés aux bords 21 et 41 par lesquels la grille et le couvercle sont articulés sur le bâti, sont connexes l'un de l'autre lorsque la grille 2 et le couvercle 4 sont en position de fermeture.As shown in Figure 1, the inner edges respective ones 22 and 42 of the grid and the cover, which are opposed to the edges 21 and 41 by which the grid and the lid are articulated on the frame, are related from each other when the grid 2 and the lid 4 are in the closed position.

La grille 2 présente, sur son bord interne 22 et en regard du bâti 1, un ou plusieurs reliefs, tels que le relief 31, portés chacun par une extrémité libre 30 d'un barreau élastique correspondant tel que 3, chaque relief étant susceptible d'être engagé dans un logement de retenue 11 du bâti 1 pour immobiliser la grille 2 en position de fermeture Z2 sur le bâti 1.The grid 2 has on its inner edge 22 and in view of the frame 1, one or more reliefs, such as the relief 31, each carried by a free end 30 of a corresponding elastic bar such as 3, each relief being likely to be engaged in a housing of retaining 11 of the frame 1 to immobilize the grid 2 in closing position Z2 on the frame 1.

Comme le montre notamment la figure 2, l'extrémité libre 30 du barreau élastique 3 est également dotée d'une encoche 32 dans laquelle peut être engagé un ergot 43 correspondant porté par le bord interne 42 du couvercle, l'engagement de l'ergot dans l'encoche permettant ainsi d'immobiliser le couvercle 4 en position de fermeture Z4, sur le bâti 1, par l'intermédiaire de la grille 2.As shown in particular in Figure 2, the free end 30 of the elastic bar 3 is also provided with a notch 32 in which can be engaged a pin 43 corresponding carried by the inner edge 42 of the lid, the engagement of the pin in the notch thus allowing to immobilize the lid 4 in the closed position Z4, on the frame 1, through the gate 2.

Comme le montre la figure 7, le logement de retenue 11 est délimité par un rebord 12, et le relief 31 présente une surface en biseau 311 qui se trouve en regard du rebord 12 pour la position d'approche de fermeture de la grille 2 illustrée sur cette figure et sur la figure 3.As shown in Figure 7, the retainer housing 11 is delimited by a flange 12, and the relief 31 presents a beveled surface 311 facing the flange 12 for the closing approach position of the grid 2 illustrated in this figure and in FIG.

A partir de cette position d'approche de fermeture de la grille 2, le relief 31 s'engage dans le logement de retenue 11 par application sur l'extrémité libre 30 du barreau élastique 3 d'une force F1 orientée suivant la direction D1, essentiellement perpendiculaire au barreau 3 (figure 7).From this closing approach position of the grid 2, the relief 31 engages in the housing of retained 11 by application on the free end 30 of the elastic bar 3 of a force F1 oriented according to the direction D1, essentially perpendicular to the bar 3 (Figure 7).

Le contact de la surface en biseau 311 sur le rebord 12 du logement de retenue 11 conduit à l'apparition d'une composante F2 de la force F1, qui opère une déflection du barreau élastique 3 suivant la direction D2, à la fois perpendiculaire à la direction D1 et au barreau élastique 3.The contact of the beveled surface 311 on the rim 12 retaining housing 11 leads to the appearance of a component F2 of the force F1, which operates a deflection of elastic bar 3 in the direction D2, both perpendicular to the direction D1 and to the elastic bar 3.

De façon symétrique, l'ouverture de la grille 2, supposée initialement en position de fermeture Z2, s'obtient en exerçant la force F2 sur l'extrémité 30 du barreau 3, cette force provoquant une déflexion du barreau 3 suivant la direction D2 qui permet de dégager le relief 31 du logement de retenue 11.In a symmetrical way, the opening of the grid 2, supposed initially in the closed position Z2, is obtained in exerting the force F2 on the end 30 of the bar 3, this force causing a deflection of the bar 3 next the direction D2 which allows to clear the relief 31 of the retainer housing 11.

A cette fin, un interstice 5 est par exemple prévu entre l'extrémité libre 30 du barreau 3 et le bâti 1 en position de fermeture Z2 de la grille 2, pour permettre l'insertion d'un levier quelconque, tel que barre à mine, propre à appliquer la force F2 sur l'extrémité libre 30 du barreau 3.For this purpose, a gap 5 is for example provided between the free end 30 of the bar 3 and the frame 1 in Z2 closing position of the grid 2, to allow the insertion of any lever, such as a bar, clean to apply the force F2 on the free end 30 of the Bar 3.

Comme le montre la figure 4, l'ergot 43 et l'encoche 32 présentent des rampes d'approche respectives, 431, 321, en regard l'une de l'autre pour la position d'approche de fermeture du couvercle 4 représentée sur cette figure. As shown in FIG. 4, the lug 43 and the notch 32 have respective approach ramps, 431, 321, facing each other for the approach position of closing the lid 4 shown in this figure.

A partir de cette position d'approche, l'ergot 43 s'engage dans l'encoche 32 par application sur l'ergot 43 d'une force F3 orientée suivant la direction D3, perpendiculaire aux directions D1, D2.From this approach position, the pin 43 engages in the notch 32 by application on the spigot 43 a force F3 oriented in the direction D3, perpendicular to the directions D1, D2.

En pratique, la force F3 est bien sûr plutôt exercée sur le couvercle lui-même, qui la transmet à l'ergot 43.In practice, the F3 force is of course rather exercised over the lid itself, which transmits it to the lug 43.

Dans ces conditions, le contact mutuel des rampes d'approche 431, 321 de l'ergot 43 et de l'encoche 32 conduit à l'apparition d'une composante F4 de la force F3, qui opère une déflection du barreau élastique 3 suivant la direction D4, colinéaire à la direction D2 et de sens inverse.Under these conditions, the mutual contact of the ramps approach 431, 321 of the lug 43 and the notch 32 leads to the appearance of an F4 component of the force F3, which operates a deflection of the elastic bar 3 following direction D4, collinear to direction D2 and in the opposite direction.

Comme le montrent les figures 2 et 5, l'ergot 43 et l'encoche 32 présentent également des rampes de retenue 432, 322 respectives, en regard l'une de l'autre pour la position de fermeture Z4 du couvercle 4.As shown in FIGS. 2 and 5, the lug 43 and notch 32 also have restraining ramps 432, 322 respectively, facing each other for the Z4 closing position of the cover 4.

Lorsque le couvercle 4 est écarté de sa position de fermeture Z4, l'ergot 43, se dégage de l'encoche 32 par application, sur l'ergot 43, d'une force F5 orientée suivant la direction D5, colinéaire à la direction D3 et de sens inverse.When the cover 4 is moved away from its position Z4 closure, the lug 43, emerges from the notch 32 by application, on the lug 43, of an oriented F5 force following direction D5, collinear to direction D3 and in the opposite direction.

Dans ces conditions, le contact mutuel des rampes de retenue 432, 322 de l'ergot 43 et de l'encoche 32 conduit à l'apparition d'une composante F40 de la force F5, qui opère une déflection du barreau élastique 3 suivant la direction D4.In these circumstances, the mutual contact of retaining 432, 322 of the lug 43 and the notch 32 leads the appearance of a component F40 of the force F5, which operates a deflection of the elastic bar 3 according to the direction D4.

La force F5 permettant d'écarter le couvercle 4 de sa position de fermeture Z4 est par exemple exercée au moyen d'un outil, tel que barre à mine ou pioche, inséré dans un dégagement latéral prévu sur la surface supérieure du couvercle, et prenant appui sur la partie correspondante du bâti.The force F5 to separate the cover 4 from its Z4 closure position is for example exerted by means a tool, such as a crowbar or pickaxe, inserted in a lateral clearance provided on the upper surface of the cover, and bearing on the corresponding part of the frame.

L'invention ainsi réalisée permet donc, dans les conditions décrites, de déplacer indépendamment l'un de l'autre le couvercle et la grille de leurs positions de fermeture respectives à leurs positions d'ouverture respectives, et inversement.The invention thus achieved thus makes it possible, in the conditions described, to independently move one of the other the cover and the grid of their positions of respective closing at their open positions respectively, and vice versa.

Claims (5)

  1. A gully, including at least one frame (1) and one metal grating (2) mounted on the frame (1) at a first edge (21) to pivot between a closed position (Z2) in which it covers at least a first portion (P1) of the frame (1) and an open position (A2), said grid (2) having at least one relief (31) on a second edge (22) opposite the first edge (21), each relief being carried by a corresponding elastic bar (3) and being selectively engaged in a retaining housing (11) of the frame (1) to immobilise the grating (2) in the closed position, which gully is characterised in that it includes a cover (4) mounted on the frame (1) at a first edge (41) to pivot between a closed position (Z4) in which it covers at least a second portion (P2) of the frame (1) and an open position (A4), said cover (4) having a second edge (42) opposite the first edge (41) and adjoining the second edge (22) of the grating (2) in the closed position (Z2, Z4) of the grating and the cover, in that the relief (31) is carried by a free end (30) of the elastic bar (3), which also has a notch (32), and in that the cover (4) has on its second edge (42) a lug (43) selectively engaged in the notch (32) to immobilise the cover (4) in the closed position (Z4) on the frame (1) by means of the grating (2).
  2. A gully according to claim 1, characterised in that the relief (31) has a bevelled surface (311) facing a rim (12) of the retaining housing (11) in an almost closed position of the grating and in that, starting from the almost closed position of the grating (2), the relief (31) is engaged in the retaining housing (11) by applying to the free end (30) of the elastic bar (3) a force oriented in a first direction (D1) essentially perpendicular to the bar (3) and a component of which, resulting from contact of the bevelled surface (311) with the rim (12) of the retaining housing (11), deflects the elastic bar (3) in a second direction (D2) essentially perpendicular to the first direction (D1) and to the elastic bar (3).
  3. A gully according to claim 2, characterised in that the lug (43) and the notch (32) have respective approach ramps (431, 321) that face each other in an almost closed position of the cover (4) and in that, starting from the almost closed position of the cover (4), the lug (43) is engaged in the notch (32) by applying to the lug (43) a force oriented in a third direction (D3) essentially perpendicular to the first and second directions (Dl, D2) and a component of which, resulting from mutual contact of the approach ramps (431, 321) of the lug (43) and the notch (32), deflects the elastic bar (3) in a fourth direction (D4) essentially perpendicular to the second direction (D2).
  4. A gully according to claim 3, characterised in that the lug (43) and the notch (32) have respective retaining ramps (432, 322) that face each other in the closed position (Z4) of the cover (4) and in that, when the cover (4) is away from its closed position (Z4), the lug (43) is disengaged from the notch (32) by applying to the lug (43) a force oriented in a fifth direction (D5) essentially opposite the third direction (D3) and a component of which, resulting from mutual contact of the retaining ramps (432, 322) of the lug (43) and the notch (32), deflects the elastic bar (3) in the fourth direction (D4).
  5. A gully according to any one of claims 2 to 4, characterised in that an interstice (5) between the free end (30) of the bar (3) and the frame (1) in the closed position (Z2) of the grating (2) enables a lever inserted therein to apply to the free end (30) of the bar (3) a force oriented in the second direction (D2) and causing deflection of the elastic bar (3) in the second direction (D2) and disengagement of the relief (31) from the retaining housing (11).
