Description

La présente invention est relative aux pièces de voirie telles que les bouches d'égouts ou les regards pour trottoirs, du type comprenant un couvercle amovible reposant, en position de fermeture, dans un cadre scellé dans le sol ou sur une structure support.The present invention relates to road parts such as manholes or manholes for sidewalks, of the type comprising a removable cover resting, in the closed position, in a frame sealed in the ground or on a support structure.

Plus particulièrement, la présente invention a pour objet des moyens pour assujettir de façon amovible une pièce de recouvrement du type grille plane ou concave, plaque ou autre, de forme générale polygonale, à un cadre coopérant avec ladite pièce. De manière préférentielle, la pièce de recouvrement selon la présente invention aura en plan une forme générale triangulaire, carrée, rectangulaire ou trapézoïdale.More particularly, the present invention relates to means for removably securing a covering piece of the flat or concave grid type, plate or other, of generally polygonal shape, to a frame cooperating with said piece. Preferably, the covering part according to the present invention will have in plan a general triangular, square, rectangular or trapezoidal shape.

Il est connu, pour verrouiller de façon amovible une grille ou plaque de recouvrement de forme générale polygonale sur un cadre support, d'utiliser une pièce mécanique rapportée du type vis, clame, crochet ou analogue. Un tel dispositif de verrouillage nécessite cependant l'utilisation d'un outil particulier pour la mise en oeuvre et risque, dans certains cas, de se déverrouiller seul sous l'effet des vibrations multiples engendrées par le passage des véhicules ; la pièce rapportée présente d'autre part le risque de se gripper, devenant ainsi difficile à manoeuvrer, voire de se bloquer, rendant ainsi son déverrouillage impossible.It is known, to removably lock a cover or cover plate of generally polygonal shape on a support frame, to use an attached mechanical part of the screw, clamp, hook or similar type. Such a locking device however requires the use of a particular tool for the implementation and risks, in certain cases, of unlocking alone under the effect of the multiple vibrations generated by the passage of vehicles; on the other hand, the insert presents the risk of seizing up, thus becoming difficult to maneuver, or even locking up, thus making it impossible to unlock.

On connaît également des dispositifs où le verrouillage est réalisé par l'emprisonnement de doigts élastiques, solidaires de la grille ou plaque, dans des logements ou sous des butées du cadre support. De telles solutions font cependant appel à l'élasticité du matériau constituant la grille ou plaque.Devices are also known where the locking is achieved by the imprisonment of elastic fingers, integral with the grid or plate, in housings or under stops of the support frame. Such solutions however call upon the elasticity of the material constituting the grid or plate.

Un autre inconvénient des systèmes de verrouillage connus réside dans le claquement de la grille ou plaque sur son support lors du passage des charges roulantes, constituant ainsi une source permanente de bruits.Another disadvantage of known locking systems lies in the slamming of the grid or plate on its support during the passage of rolling loads, thus constituting a permanent source of noise.

La présente invention a donc pour but de s'affranchir de ces inconvénients.The present invention therefore aims to overcome these drawbacks.

Plus particulièrement, la présente invention a pour objet, à cet effet, des moyens destinés à assujettir de façon amovible une pièce de recouvrement de forme générale polygonale, du type grille plane ou concave ou plaque de recouvrement, à un cadre coopérant avec ladite pièce, ces moyens comprenant au moins un organe élastique positionné dans un logement ouvert aménagé dans la région médiane d'une des faces latérales du cadre, au moins un bec d'accrochage solidaire de la face latérale du cadre opposée à celle où se situe l'organe élastique, un doigt, solidaire de la pièce de recouvrement, dont l'extrémité inférieure présente un bourrelet adapté pour s'encliqueter par coopération avec ledit bec d'accrochage, et une barrette, solidaire de la pièce, qui, en position de fermeture de ladite pièce de recouvrement sur le cadre, coopère avec l'organe élastique, le bec d'accrochage se trouvant alors en position encliquetée avec le doigt de la pièce de recouvrement.More particularly, the object of the present invention is, for this purpose, means intended to removably secure a covering part of generally polygonal shape, of the flat or concave grid type or covering plate, to a frame cooperating with said part, these means comprising at least one elastic member positioned in an open housing arranged in the middle region of one of the side faces of the frame, at least one hooking spout secured to the side face of the frame opposite to that where the member is located elastic, a finger, integral with the covering part, the lower end of which has a bead adapted to snap by cooperation with said hooking spout, and a bar, integral with the part, which, in the closed position of said covering part on the frame cooperates with the elastic member, the hooking spout then being in the snapped-in position with the finger of the covering part rement.

Ces moyens combinés offrent ainsi une sécurité de verrouillage qui évite que la grille ou plaque, de par son faible poids, ne soit éjectée hors du cadre lors du passage de véhicules, ce tout en supprimant les bruits de claquement pouvant résulter de ces passages de charges roulantes.These combined means thus offer locking security which prevents the grid or plate, by virtue of its low weight, from being ejected from the frame during the passage of vehicles, while eliminating the clicking noises which may result from these passage of charges. rolling.

La présente invention a également pour objet une pièce de voirie du type comprenant une pièce de recouvrement de forme générale polygonale coopérant avec un cadre support, ladite pièce de voirie comportant les moyens d'assujettissement de la pièce de recouvrement au cadre tels que définis ci-dessus, à savoir au moins un organe élastique situé dans un logement ouvert aménagé dans la région médiane d'une des faces latérales du cadre, et une barrette solidaire de la pièce de recouvrement, qui, en position de fermeture de ladite pièce de recouvrement sur la cadre, coopère avec l'organe élastique, au moins un bec d'accrochage solidaire de la face latérale opposée à celle où se situe ledit organe élastique se trouvant alors en position encliquetée avec un doigt solidaire de la pièce de recouvrement.The present invention also relates to a road part of the type comprising a covering part of generally polygonal shape cooperating with a support frame, said road part comprising the means for securing the covering part to the frame as defined above. above, namely at least one elastic member located in an open housing arranged in the middle region of one of the lateral faces of the frame, and a bar secured to the covering part, which, in the closed position of said covering part on the frame cooperates with the elastic member, at least one hooking spout secured to the side face opposite to that where said elastic member is then located in the latched position with a finger secured to the covering part.

Dans chacun de ces élargissements 8A, 8B est ménagée une ouverture 9A, respectivement 9B, de direction longitudinale l'axe Y-Y, l'ouverture 9B de l'élargissement 8B étant plus longue que l'ouverture 9A de l'élargissement 8A.In each of these widenings 8A, 8B is formed an opening 9A, respectively 9B, of longitudinal direction the axis Y-Y, the opening 9B of the widening 8B being longer than the opening 9A of the widening 8A.

Ces deux ouvertures 9A, 9B sont en regard l'une de l'autre et présentent en coupe, comme représenté à la Fig. 4, une section ayant la forme générale d'un triangle à sommets arrondis, laissant ainsi apparaître dans sa partie verticale la plus intérieure au cadre 1 une portion verticale sensiblement oblongue, et dans sa partie la plus basse, une portion horizontale sensiblement oblongue.These two openings 9A, 9B are opposite one another and have in section, as shown in FIG. 4, a section having the general shape of a triangle with rounded vertices, thus revealing in its vertical part most internal to the frame 1 a substantially oblong vertical portion, and in its lowest part, a substantially oblong horizontal portion.

La jupe 3 est terminée par une face latérale 10 opposée et parallèle à la face latérale 7.The skirt 3 is terminated by a side face 10 opposite and parallel to the side face 7.

La face latérale 10 comporte, à ses extrémités, deux becs d'accrochage 11 en saillie vers l'intérieur du cadre 1, solidaires de la face interne du sommet de la jupe 3 et présentant en coupe, en considérant la figure 4, une double came comprenant une rampe supérieure 11A inclinée vers le bas, c'est-à-dire vers la base du cadre 1, et une rampe inférieure 11B inclinée vers le haut, c'est-à-dire vers le sommet du cadre 1, l'intersection de ces deux rampes 11A et 11B définissant une ligne de crêté 12 parallèle à l'axe Y-Y.The lateral face 10 comprises, at its ends, two hooking nozzles 11 projecting towards the inside of the frame 1, integral with the internal face of the top of the skirt 3 and having in section, considering FIG. 4, a double cam comprising an upper ramp 11A inclined downwards, that is to say towards the base of the frame 1, and a lower ramp 11B inclined upwards, that is to say towards the top of the frame 1, l 'intersection of these two ramps 11A and 11B defining a crest line 12 parallel to the axis YY.

Chacune des faces latérales 5, 6, 10 de la jupe 3 présente dans sa région médiane, deux plots d'appui 13, en saillie vers l'intérieur du cadre 1 et à portée supérieure 14 parallèle au plan du cadre 1.Each of the lateral faces 5, 6, 10 of the skirt 3 has, in its central region, two support studs 13, projecting towards the inside of the frame 1 and with upper reach 14 parallel to the plane of the frame 1.

Chacune des faces latérales 5, 6 de la jupe 3 présente, en saillie vers l'intérieur du cadre 1, deux plots d'appui à portée supérieure parallèle au plan du cadre, dont l'un 15 se situe à proximité de l'extrémité proche de la face latérale 10, et par conséquent à proximité des becs d'accrochage 11, et l'autre 16 se situe dans le coin opposé.Each of the side faces 5, 6 of the skirt 3 has, projecting towards the inside of the frame 1, two studs of support at higher range parallel to the plane of the frame, one of which 15 is located near the end close to the lateral face 10, and consequently close to the hooking nozzles 11, and the other 16 is located in the opposite corner.

Les plots d'appui 16 sont, par une extrémité de leur portée supérieure, solidaires de la face latérale 7 de la jupe 3, la face supérieure de leur portée supérieure, parallèle au plan du cadre, se situant, en considérant la Fig. 5, à un niveau plus bas que les ouvertures 9A, 9B.The support pads 16 are, at one end of their upper reach, secured to the lateral face 7 of the skirt 3, the upper face of their upper reach, parallel to the plane of the frame, being situated, considering FIG. 5, at a level lower than the openings 9A, 9B.

La face latérale 7 présente dans sa région médiane, et de préférence centré, un plot d'appui 17 à portée supérieure 18 dont la face supérieure 18A et la face inférieure 18B, en considérant la Fig. 5, sont parallèles au plan du cadre 1.The lateral face 7 has, in its central region, and preferably centered, a support pad 17 with upper reach 18, the upper face 18A and the lower face 18B, considering FIG. 5, are parallel to the plane of the frame 1.

Cette portée supérieure 18 présente, en considérant les Fig. 3 à 5, un évidement centré 19, ouvert vers l'intérieur du cadre, de forme générale rectangulaire, partageant ainsi la portée supérieure 18 en deux protubérances 20A, 20B reliées entre elles par une branche longitudinale 21, parallèle à l'axe Y-Y, et venue de matière avec la face latérale 7 de la jupe 3.This upper range 18 has, considering Figs. 3 to 5, a centered recess 19, open towards the inside of the frame, of generally rectangular shape, thus dividing the upper surface 18 into two protuberances 20A, 20B connected together by a longitudinal branch 21, parallel to the axis YY, and integral with the lateral face 7 of the skirt 3.

La face inférieure 18B se prolonge aux extrémités intérieures des protubérances 20A, 20B, parallèlement à la face latérale 7, par une lèvre 22 en saillie verticale vers la base du cadre 1.The lower face 18B is extended at the inner ends of the protrusions 20A, 20B, parallel to the lateral face 7, by a lip 22 projecting vertically towards the base of the frame 1.

La région médiane de la face latérale 7 se prolonge vers l'intérieur du cadre 1 par une excroissance longitudinale 23, parallèle au plan du cadre, de forme générale rectangulaire solidaire de la face interne de lajupe 3 et coplanaire avec la semelle 4 qui, en considérant les Fig. 3 à 5, vient se positionner entre les protubérances 20A et 20B, c'est-à-dire sous l'évidement 19, les extrémités intérieures au cadre 1 et parallèles à la face 7 des protubérances 20A, 20B et de l'excroissance 23 étant situées dans un même plan vertical.The middle region of the lateral face 7 is extended towards the inside of the frame 1 by a longitudinal protuberance 23, parallel to the plane of the frame, of generally rectangular shape integral with the internal face of the skirt 3 and coplanar with the sole 4 which, in considering Figs. 3 to 5, is positioned between the protrusions 20A and 20B, that is to say under the recess 19, the ends inside the frame 1 and parallel to the face 7 of the protrusions 20A, 20B and the protuberance 23 being located in the same vertical plane.

La face supérieure de l'excroissance 23 se prolonge dans la région médiane de son extrémité la plus intérieure au cadre 1, et parallèlement à la face latérale 7, par une lèvre 24 en saillie verticale vers le sommet du cadre 1, cette lèvre 24 étant de préférence centrée par rapport aux extrémités transversales 23A et 23B, parallèles à l'axe X-X, de l'excroissance 23.The upper face of the protuberance 23 extends in the median region from its innermost end to the frame 1, and parallel to the lateral face 7, by a lip 24 projecting vertically towards the top of the frame 1, this lip 24 preferably being centered relative to the transverse ends 23A and 23B, parallel to the axis XX, of l outgrowth 23.

Les lèvres 22 et 24 sont telles que la face supérieure de la lèvre 24 se situe à un niveau plus bas que la face inférieure de la lèvre 22.The lips 22 and 24 are such that the upper face of the lip 24 is located at a lower level than the lower face of the lip 22.

La face inférieure du plot d'appui 17, dont les protubérances 20A, 20B sont munies d'une lèvre 22, et la face supérieure de l'excroissance 23 munie de la lèvre 24, définissent ainsi, avec la paroi interne de la face latérale 7 de la jupe 3, un logement ouvert 25 destiné à recevoir, par coopération, un organe élastique 26 de préférence constitué par une pièce en élastomère. Dans une variante de réalisation selon l'invention, l'organe élastique 26 est constitué par un ressort.The underside of the support stud 17, the protrusions 20A, 20B of which are provided with a lip 22, and the upper face of the protuberance 23 provided with the lip 24, thus define, with the internal wall of the lateral face 7 of the skirt 3, an open housing 25 intended to receive, by cooperation, an elastic member 26 preferably constituted by an elastomer part. In an alternative embodiment according to the invention, the elastic member 26 is constituted by a spring.

En considérant la Fig. 6, cet organe élastique 26 a la forme générale d'un parallélépipède rectangle présentant d'une part, à ses extrémités transversales, deux entailles supérieures 27A, 27B destinées à coopérer respectivement avec les protubérances 20A et 20B munies chacune de leur lèvre d'extrémité 22, et d'autre part, à la base d'une extrémité longitudinale, une entaille inférieure 27C destinée à coopérer avec la lèvre 24 de l'excroissance 23. Lorsque l'organe élastique 26 est positionné dans son logement 25, sa face inférieure repose en partie sur la face supérieure de l'excroissance 23, et sa face supérieure vient se placer dans l'évidement 19, et ce à un niveau compris entre la face inférieure 18B et la face supérieure 18A de la portée supérieure 18 ; la face verticale de l'organe élastique 26 opposée à celle où se situe l'entaille inférieure 27C se positionne alors, par son sommet, en regard de la branche longitudinale 21 du plot d'appui 17. L'organe élastique 26, de par la disposition particulière des lèvres 22 et 24 et des pièces supportant lesdites lèvres, se trouve ainsi emprisonné de manière parfaitement stable dans son logement 25.Considering FIG. 6, this elastic member 26 has the general shape of a rectangular parallelepiped having on the one hand, at its transverse ends, two upper notches 27A, 27B intended to cooperate respectively with the protuberances 20A and 20B each provided with their end lip 22, and secondly, at the base of a longitudinal end, a lower notch 27C intended to cooperate with the lip 24 of the protuberance 23. When the elastic member 26 is positioned in its housing 25, its lower face partly rests on the upper face of the protrusion 23, and its upper face is placed in the recess 19, and this at a level between the lower face 18B and the upper face 18A of the upper surface 18; the vertical face of the elastic member 26 opposite to that where the lower notch 27C is located is then positioned, by its apex, facing the longitudinal branch 21 of the support pad 17. The elastic member 26, by the particular arrangement of the lips 22 and 24 and of the parts supporting the said lips is thus trapped in a perfectly stable manner in its housing 25.

Les plots d'appui 13, 15, 16 et 17, en saillie vers l'intérieur du cadre 1, sont tels que les faces supérieures de leurs portées supérieures, parallèles au plan du cadre 1, sont coplanaires et constituent ainsi des surfaces plates sur lesquelles la grille 2, en position de fermeture, va venir prendre appui.The support pads 13, 15, 16 and 17, projecting towards the inside of the frame 1, are such that the upper faces of their upper bearing surfaces, parallel to the plane of the frame 1, are coplanar and thus constitute flat surfaces on which the grid 2, in the closed position, will come to bear.

La grille 2, en considérant les Fig. 1 et 2, est constituée d'une série de barreaux 28, parallèles à l'axe Y-Y, et reliés entre eux par au moins deux entretoises 29, parallèles à l'axe X-X, deux des entretoises 29 reposant en position de fermeture par leurs extrémités, sur les portées supérieures plates des plots d'appui 13 et 17 des faces latérales 10 et 7 du cadre 1. Les barreaux 28, espacés régulièrement et se terminant par deux barreaux 28A, 28B d'extrémité, sont positionnés de manière telle que deux d'entre eux reposent, en position de fermeture, par l'intermédiaire de leurs extrémités, sur les portées supérieures plates des plots d'appui 13 des faces latérales 5 et 6 du cadre 1.Grid 2, considering Figs. 1 and 2, consists of a series of bars 28, parallel to the axis YY, and interconnected by at least two spacers 29, parallel to the axis XX, two of the spacers 29 resting in the closed position by their ends, on the flat upper surfaces of the support pads 13 and 17 of the side faces 10 and 7 of the frame 1. The bars 28, regularly spaced and ending with two end bars 28A, 28B, are positioned so that two of them rest, in the closed position, via their ends, on the flat upper surfaces of the support pads 13 of the side faces 5 and 6 of the frame 1.

Le barreau d'extrémité 28A, situé à proximité de la face latérale 10 du cadre 1, repose, en position de fermeture, par ses extrémités, sur les portées supérieures plates des plots d'appui 15 du cadre 1, chacune de ses extrémités se prolongeant vers l'extérieure de la grille, parallèlement à l'axe X-X, par un doigt 30 en saillie vers le bas, sensiblement perpendiculairement au plan de la grille. En considérant la Fig. 2, les doigts 30 se terminent, à leur extrémité inférieure, par un bourrelet 31 comportant une rampe 31A inclinée vers le bas, dirigée vers l'extérieur de la grille 2, et une surface inférieure 31B sensiblement parallèle au plan de la grille 2, la rampe 31A étant reliée à la surface 31B par l'intermédiaire d'une surface sensiblement arrondie 31C.The end bar 28A, located near the lateral face 10 of the frame 1, rests, in the closed position, by its ends, on the flat upper surfaces of the support pads 15 of the frame 1, each of its ends extending towards the outside of the grid, parallel to the axis XX, by a finger 30 projecting downward, substantially perpendicular to the plane of the grid. Considering FIG. 2, the fingers 30 terminate, at their lower end, by a bead 31 comprising a ramp 31A inclined downwards, directed towards the outside of the grid 2, and a lower surface 31B substantially parallel to the plane of the grid 2, the ramp 31A being connected to the surface 31B via a substantially rounded surface 31C.

Les rampes 31A des doigts 30, dont l'inclinaison correspond à celle des rampes 11B des becs d'accrochage 11 sont situées en position de fermeture en regard des becs d'accrochage 11. Le barreau d'extrémité 28B, situé à proximité de la face latérale 7 du cadre 1, repose, en position de fermeture, par ses extrémités sur la portée supérieure plate des plots d'appui 16 du cadre 1 et présente, dans sa région médiane et de préférence centrée, une barrette 32 de forme générale rectangulaire, parallèle à l'axe Y-Y, faisant saillie vers le bas de la grille 2, sensiblement perpendiculairement au plan de cette dernière. Lorsque la grille 2 repose sur le cadre 1, cette barrette 32 se positionne, de manière centrée, en regard de l'extrémité longitudinale la plus intérieure au cadre 1 de l'organe élastique 26, sa dimension longitudinale étant moindre que la distance séparant les deux protubérances 20A et 20B, et sa face inférieure 32A se situant au dessus de la face supérieure de la lèvre 24 de l'excroissance 23. Les extrémités du barreau 28B sont en saillie, parallèlement à l'axe X-X, vers l'extérieur de la grille 2, chacune des deux faces externes dudit barreau 28B, parallèles à l'axe X-X, comportant un pivot cylindrique 33A, respectivement 33B, en saillie vers l'extérieur de la grille, parallèlement à l'axe Y-Y.The ramps 31A of the fingers 30, the inclination of which corresponds to that of the ramps 11B of the attachment lugs 11 are located in the closed position opposite the attachment lugs 11. The end bar 28B, located at near the side face 7 of the frame 1, rests, in the closed position, by its ends on the flat upper surface of the support pads 16 of the frame 1 and has, in its central region and preferably centered, a bar 32 of generally rectangular shape, parallel to the axis YY, projecting downwards from the grid 2, substantially perpendicular to the plane of the latter. When the grid 2 rests on the frame 1, this bar 32 is positioned, in a centered manner, opposite the longitudinal end most internal to the frame 1 of the elastic member 26, its longitudinal dimension being less than the distance separating the two protrusions 20A and 20B, and its lower face 32A lying above the upper face of the lip 24 of the protuberance 23. The ends of the bar 28B are projecting, parallel to the axis XX, towards the outside of the grid 2, each of the two external faces of the said bar 28B, parallel to the axis XX, comprising a cylindrical pivot 33A, respectively 33B, projecting towards the outside of the grid, parallel to the axis YY.

Ces deux pivots 33A et 33B sont coaxiaux, de longueur différente, le pivot 33A étant plus court que le pivot 33B, et sont destinés, lors du montage de la grille 2 sur le cadre 1, à venir se loger respectivement dans les ouvertures 9A et 9B ménagées dans les élargissements respectifs 8A et 8B du cadre 1, permettant ainsi l'articulation de la grille 2 par rapport au cadre 1 ; la longueur du pivot 33B est telle que lorsque celui-ci est entièrement introduit dans l'ouverture 9B, le pivot 33A se trouve en dehors de l'ouverture 9A, et le diamètre de ces pivots 33A, 33B est tel que ceux-ci peuvent subir des mouvements de translation horizontale et verticale dans les portions sensiblement oblongues, respectivement horizontales et verticales, des ouvertures respectives 9A et 9B destinées à les recevoir.These two pivots 33A and 33B are coaxial, of different length, the pivot 33A being shorter than the pivot 33B, and are intended, when mounting the grid 2 on the frame 1, to be housed respectively in the openings 9A and 9B formed in the respective enlargements 8A and 8B of the frame 1, thus allowing the articulation of the grid 2 relative to the frame 1; the length of the pivot 33B is such that when the latter is fully inserted into the opening 9B, the pivot 33A is located outside the opening 9A, and the diameter of these pivots 33A, 33B is such that these can undergo horizontal and vertical translational movements in the substantially oblong, respectively horizontal and vertical portions, of the respective openings 9A and 9B intended to receive them.

En ce qui concerne le barreau 28B (Fig. 1), l'extrémité se situant, en position de fermeture de la grille 2, à proximité de la face latérale 6 du cadre 1 se prolonge également dans sa partie la plus éloignée de la face latérale 7 par une proéminence 34 dirigée vers l'extérieur de la grille 2, parallèlement à l'axe Y-Y, qui, dans la position de fermeture, se situe en regard de la face interne de la jupe 3, évitant ainsi toute possibilité de délogement accidentel du pivot 33A ; cette proéminence 34 définit avec la surface cylindrique externe du pivot 33B un espace libre 35 dans lequel peut venir se loger la paroi supérieure, d'épaisseur E, de l'élargissement 8B.Regarding the bar 28B (Fig. 1), the end being in the closed position of the grid 2, near the lateral face 6 of the frame 1 also extends in its part furthest from the lateral face 7 by a protrusion 34 directed towards the outside of the grid 2, parallel to the axis YY, which, in the closed position, is located opposite the internal face of the skirt 3, thus avoiding any possibility of accidental dislodging of the pivot 33A; this prominence 34 defines with the external cylindrical surface of the pivot 33B a free space 35 in which can be accommodated the upper wall, of thickness E, of the widening 8B.

Pour monter la grille 2 de façon articulée sur le cadre 1, on présente cette dernière perpendiculairement au plan du cadre et on introduit le pivot 33B à fond dans l'ouverture 9B, ce dernier venant se positionner dans la partie haute de la portion oblongue verticale de l'ouverture 9B. Le pivot 33A se situe alors en regard de la partie haute de la portion oblongue verticale de l'ouverture 9A, c'est-à-dire, en considérant la Fig. 4, en regard de l'espace supérieur gauche de l'ouverture 9A, la proéminence 34 se situant alors au-dessus de l'élargissement 8B dont l'épaisseur E de la paroi supérieure vient se loger dans l'espace libre 35 compris entre le pivot 33B et la proéminence 34.To mount the grid 2 in an articulated manner on the frame 1, the latter is presented perpendicularly to the plane of the frame and the pivot 33B is fully inserted into the opening 9B, the latter being positioned in the upper part of the vertical oblong portion of opening 9B. The pivot 33A is then located opposite the upper part of the oblong vertical portion of the opening 9A, that is to say, considering FIG. 4, opposite the upper left space of the opening 9A, the protrusion 34 then being located above the enlargement 8B, the thickness E of the upper wall of which is housed in the free space 35 between the pivot 33B and the prominence 34.

Puis, en maintenant la grille 2 en position verticale, on translate celle-ci horizontalement de manière à amener le pivot 33A dans l'ouverture 9A, la face externe de la proéminence 34, parallèle à la face latérale 6 du cadre 1, venant se placer dans un plan sensiblement vertical, adjacent au plan contenant la face interne de la face latérale 6 de la jupe 3. La grille 2 toujours maintenue en position perpendiculaire au plan du cadre 1, on translate alors celle-ci vers le bas, les pivots 33A et 33B venant ainsi se positionner dans la partie basse de la portion oblongue verticale des ouvertures respectives 9A et 9B, et la proéminence 34 venant, par l'intermédiaire de sa face externe parallèle à la face latérale 6 du cadre 1, se positionner en regard de la paroi supérieure de l'élargissement 8B.Then, while maintaining the grid 2 in a vertical position, the latter is translated horizontally so as to bring the pivot 33A into the opening 9A, the external face of the prominence 34, parallel to the lateral face 6 of the frame 1, coming place in a substantially vertical plane, adjacent to the plane containing the internal face of the lateral face 6 of the skirt 3. The grid 2 still maintained in a position perpendicular to the plane of the frame 1, the latter is then translated downwards, the pivots 33A and 33B thus positioned in the lower part of the oblong vertical portion of the respective openings 9A and 9B, and the protrusion 34 coming, by means of its external face parallel to the lateral face 6 of the frame 1, to be positioned in look of the upper wall of the enlargement 8B.

La grille 2 se trouve ainsi en position ouverte, articulée par rapport au cadre 1 par l'intermédiaire des pivots 33A et 33B qui constituent son axe de rotation.The grid 2 is thus in the open position, articulated relative to the frame 1 by means of the pivots 33A and 33B which constitute its axis of rotation.

Le verrouillage de la grille 2 sur son cadre support consiste dans un premier temps à abaisser cette dernière, depuis la position d'ouverture, par pivotement autour de son axe de rotation, et ce jusqu'à amener la surface arrondie 31C du bourrelet 31 des doigts 30 en contact avec la rampe supérieure 11A des becs d'accrochage 11 du cadre 1, la barrette 32 se situant alors en regard de l'organe élastique 26.The locking of the grid 2 on its support frame consists firstly in lowering the latter, from the open position, by pivoting about its axis of rotation, and this until bringing the rounded surface 31C of the bead 31 of the fingers 30 in contact with the upper ramp 11A of the attachment nozzles 11 of the frame 1, the bar 32 then being located opposite the elastic member 26.

A cet effet, de par sa position en feuillure de la jupe 3, la proéminence 34 permet d'une part de guider la grille 2 lors de son positionnement dans le cadre, empêchant notamment tout déplacement de cette dernière parallèlement à son axe d'articulation, et permet d'autre part, par son action de centrage, de bien maintenir la barrette 32 en regard de l'organe élastique 26.To this end, by its rebate position of the skirt 3, the prominence 34 allows on the one hand to guide the grid 2 when it is positioned in the frame, preventing in particular any movement of the latter parallel to its axis of articulation. , and on the other hand allows, by its centering action, to properly hold the bar 32 facing the elastic member 26.

Dans un second temps, pour poursuivre le verrouillage de la grille 2, il suffit alors d'exercer sur cette dernière, une poussée dirigée vers le bas, la barrette 32 prenant ainsi appui sur l'organe élastique 26 et venant progressivement comprimer ce dernier dans son logement 25, et de maintenir cette poussée jusqu'à ce que la surface arrondie 31C du bourrelet 31, en glissant le long de la rampe supérieure 11A des becs d'accrochage 11, atteigne puis franchisse la ligne de crêté 12 des becs d'accrochage 11, ce franchissement correspondant au taux de compression maximal de l'organe élastique 26. Durant cette étape de compression, les pivots 33A et 33B se déplacent, vers l'extérieur du cadre, par translation parallèlement au plan du cadre 1, le long de la portion horizontale sensiblement oblongue des ouvertures respectives 9A et 9B.In a second step, to continue locking the grid 2, it then suffices to exert on the latter, a downward thrust, the bar 32 thus bearing on the elastic member 26 and gradually compressing the latter in its housing 25, and to maintain this thrust until the rounded surface 31C of the bead 31, by sliding along the upper ramp 11A of the attachment nozzles 11, reaches then crosses the crest line 12 of the nozzles attachment 11, this crossing corresponding to the maximum compression rate of the elastic member 26. During this compression step, the pivots 33A and 33B move, towards the outside of the frame, by translation parallel to the plane of the frame 1, along of the substantially oblong horizontal portion of the respective openings 9A and 9B.

Ensuite, après avoir franchi la ligne de crête 12, le bourrelet 31, par décompression progressive de l'organe élastique 26, glisse le long de la rampe inférieure 11B des becs d'accrochage 11, et ce jusqu'à amener la rampe 31A des doigts 30 en contact avec ladite rampe inférieure 11B, obtenant ainsi une position encliquetée des doigts 30 avec les becs d'accrochage 11 qui correspond à la position verrouillée finale. Durant cette étape de décompression, les pivots 33A et 33B se déplacent, par translation parallèlement au plan du cadre 1, dans le sens inverse de celui décrit dans l'étape précédente de compression. En position finale de verrouillage, c'est-à-dire en position de fermeture de la grille 2, la barrette 32 prend appui sur l'organe élastique 26 et maintient ainsi ce dernier sous légère compression. Cette précontrainte de l'organe élastique 26 permet d'amortir et d'absorber tout déplacement de la grille 2 dans la feuillure du cadre 1, notamment lors du passage de charges roulantes, et évite par conséquent les bruits de claquement ou de battement pouvant en résulter.Then, after having crossed the crest line 12, the bead 31, by progressive decompression of the elastic member 26, slides along the lower ramp 11B of the hooking nozzles 11, and this until bringing the ramp 31A of the fingers 30 in contact with said lower ramp 11B, thus obtaining a snapped-in position of fingers 30 with the hooking spouts 11 which corresponds to the final locked position. During this decompression step, the pivots 33A and 33B move, by translation parallel to the plane of the frame 1, in the opposite direction to that described in the previous compression step. In the final locking position, that is to say in the closing position of the grid 2, the bar 32 bears on the elastic member 26 and thus maintains the latter under slight compression. This prestressing of the elastic member 26 makes it possible to absorb and absorb any movement of the grid 2 in the rebate of the frame 1, in particular during the passage of rolling loads, and consequently avoids clicking or flapping noises which can result.

Pour réaliser le déverrouillage de la grille 2, il suffit d'introduire une barre entre deux barreaux 28 adjacents et d'exercer un effort de levier. La barrette 32 comprime alors l'organe élastique 26, permettant ainsi à la surface 31C du bourrelet 31 de franchir la ligne de crête 12 des becs d'accrochage 11, l'organe élastique 26 revenant ensuite à sa position de repos, c'est-à-dire à l'état non comprimé. Comme on le comprend aisément, ce démontage ne peut pas se produire accidentellement.To unlock the grid 2, it suffices to introduce a bar between two adjacent bars 28 and to exert a leverage. The bar 32 then compresses the elastic member 26, thus allowing the surface 31C of the bead 31 to cross the crest line 12 of the hooking nozzles 11, the elastic member 26 then returning to its rest position, this is ie in the uncompressed state. As is easily understood, this disassembly cannot happen accidentally.

En variante, pour rendre le déverrouillage de la grille encore plus difficile, les rampes d'accrochage 11B et 31A, destinées à coopérer ensemble, peuvent être remplacées par des surfaces horizontales.Alternatively, to make unlocking the grid even more difficult, the attachment ramps 11B and 31A, intended to cooperate together, can be replaced by horizontal surfaces.

L'exemple de réalisation qui vient d'être décrit se rapporte à une grille articulée, mais il est cependant possible d'envisager une solution où une grille plane ou concave, ou une plaque de recouvrement, repose de manière non articulée sur un cadre support. Dans ce cas les pivots 33A, 33B peuvent, par exemple, être remplacés par un système d'encliquetage du type comprenant des doigts solidaires de la grille ou plaque, destinés à venir s'encliqueter par coopération avec des becs d'accrochage solidaires de la jupe du cadre, au moins un organe élastique, positionné dans un logement dudit cadre prévu à cet effet, offrant des avantages identiques à ceux mentionnés précédemment.The embodiment which has just been described relates to an articulated grid, but it is however possible to envisage a solution where a flat or concave grid, or a cover plate, rests in a non-articulated manner on a support frame . In this case, the pivots 33A, 33B can, for example, be replaced by a latching system of the type comprising fingers secured to the grid or plate, intended to snap in by cooperation with hooking spouts secured to the skirt of the frame, at least one elastic member, positioned in a housing of said frame provided for this purpose, offering advantages identical to those mentioned above.
