Sur les figures est représenté un dispositif de voirie selon l'invention, désigné par la référence générale 2. Le dispositif de voirie 2 comporte un cadre 4, un élément de recouvrement formé par un tampon 6, et un joint d'insonorisation 8. Le dispositif de voirie 2 comporte une charnière 10 articulant le tampon 6 par rapport au cadre 4. In the figures is shown a road device according to the invention, designated by the general reference 2. The road device 2 comprises a frame 4, a covering element formed by a buffer 6, and a soundproofing joint 8. The road device 2 comprises a hinge 10 articulating the buffer 6 with respect to the frame 4.
Le cadre 4 définit une ouverture d'accès centrale 12 et comporte un rebord intérieur 14 sur lequel est disposé le joint d'insonorisation 8. Le cadre 4 définit une surface supérieure 16 entourant l'ouverture d'accès centrale 12 et s'étendant selon un plan de cadre PC. A l'état installé, le plan de cadre PC est sensiblement parallèle au sol et est de préférence aligné avec la surface du sol. Le cadre 4 est par exemple fabriqué en fonte.  The frame 4 defines a central access opening 12 and has an inner rim 14 on which the soundproofing gasket 8 is arranged. The frame 4 defines an upper surface 16 surrounding the central access opening 12 and extending along a PC frame plan. In the installed state, the PC frame plane is substantially parallel to the ground and is preferably aligned with the ground surface. The frame 4 is for example made of cast iron.
Le tampon 6 comporte un voile de fermeture 18 s'appliquant à l'état fermé sur le joint d'insonorisation 8. Le voile de fermeture 18 définit un plan de tampon PT qui s'étend à l'état fermé parallèlement au plan de cadre PC. Le tampon 6 est fabriqué par exemple en fonte.  The buffer 6 has a closing web 18 applied in the closed state to the soundproofing joint 8. The closing web 18 defines a buffer plane PT which extends in the closed state parallel to the frame plane PC. The buffer 6 is made for example of cast iron.
La charnière 10 articule le tampon 6 par rapport au cadre 4 entre une position de fermeture, représentée sur la figure 3, et une position d'ouverture à 90°, montrée sur la figure 5, ainsi qu'une position d'ouverture maximale, montrée sur la figure 7.  The hinge 10 articulates the pad 6 with respect to the frame 4 between a closed position, shown in FIG. 3, and a 90 ° open position, shown in FIG. 5, as well as a maximum open position, shown in Figure 7.
Dans la position de fermeture le tampon 6 recouvre l'ouverture d'accès centrale 12 du cadre 4. Les deux plans PC et PT coïncident alors sensiblement.  In the closed position the buffer 6 covers the central access opening 12 of the frame 4. The two planes PC and PT then coincide substantially.
Dans la position d'ouverture à 90°, le tampon 6 n'obture plus l'ouverture d'accès centrale 12 du cadre 4 et le plan PT est disposé à angle droit par rapport au plan PC.  In the open position at 90 °, the buffer 6 no longer closes the central access opening 12 of the frame 4 and the plane PT is arranged at right angles to the plane PC.
Dans la position d'ouverture maximale, le tampon 6 a effectué un basculement de plus de 90° par rapport à la position de fermeture. Dans le cas présent, l'angle de décalage entre la position de fermeture et la position d'ouverture maximale est de 1 10° environ.  In the maximum open position, the pad 6 has tilted more than 90 ° with respect to the closed position. In the present case, the offset angle between the closed position and the maximum open position is about 10 °.
La charnière 10 comprend un charnon de cadre 20 (voir figure 4) et un charnon de tampon 22.  The hinge 10 comprises a frame knuckle 20 (see FIG. 4) and a knuckle 22.
Le charnon de cadre 20 est un évidement qui forme une surface de came 24. Le charnon de cadre 20 définit un axe de charnon de cadre ACC. Le charnon de cadre 20 est formé d'une seule pièce avec le cadre 4.  The frame knuckle 20 is a recess which forms a cam surface 24. The frame knuckle 20 defines a frame knuckle axis ACC. The frame knuckle 20 is formed in one piece with the frame 4.
Le charnon de tampon 22 est une saillie 26 définissant un axe de charnon de tampon ACT. Le charnon de tampon 22 est formé d'une seule pièce avec le tampon 6 ou le voile de fermeture 18.  The buffer knuckle 22 is a protrusion 26 defining a hub axis of ACT buffer. The buffer knuckle 22 is formed in one piece with the pad 6 or the closure web 18.
Le cadre 4 comporte une ouverture d'assemblage 28 débouchant dans le charnon de cadre 20 et adaptée pour le passage du charnon de tampon 22 lors de l'assemblage du cadre 4 et du tampon 6. Lors de l'assemblage, le tampon 6 est dans une position d'assemblage dans laquelle le plan de tampon PT réalise avec le plan de cadre PC un angle compris entre 80° et 100° environ, cet angle correspondant à une plage de positions d'assemblage incluant notamment la position d'ouverture à 90°. La direction d'assemblage du charnon de tampon 22 et du charnon de cadre 20 est essentiellement radiale par rapport à l'axe du charnon de cadre ACC. The frame 4 comprises an assembly opening 28 opening into the frame hinge 20 and adapted for the passage of the buffer knuckle 22 during the assembly of the frame 4 and the buffer 6. During assembly, the buffer 6 is in an assembly position in which the buffer plane PT makes an angle of between about 80 ° and 100 ° with the PC frame plane, this angle corresponding to a range of assembly positions including in particular the 90 ° open position. The assembly direction of the buffer knuckle 22 and the frame knuckle 20 is substantially radial with respect to the axis of the ACC frame knuckle.
Le charnon de cadre 20 est surplombé par des lèvres de retenue 30, 32 situées en regard. Ces lèvres 30, 32 délimitent l'ouverture d'assemblage 28 et sont fabriquées d'un seul tenant avec le cadre 4.  The frame knuckle 20 is overhung by retaining lips 30, 32 located opposite. These lips 30, 32 delimit the assembly opening 28 and are manufactured in one piece with the frame 4.
Le dispositif de voirie 2 comporte également un élément de blocage 40 rapporté au charnon de tampon 22 après assemblage de celui-ci avec le charnon de cadre 20. Cet élément de blocage 40 est adapté pour empêcher une libération du charnon de tampon 22 du charnon de cadre 20 lorsque le tampon est dans une position angulaire par rapport au cadre correspondant à une position d'assemblage.  The road device 2 also comprises a locking element 40 attached to the buffer knuckle 22 after assembly thereof with the frame knuckle 20. This locking element 40 is adapted to prevent a release of the knuckle knuckle 22 from the knuckle 22. frame 20 when the pad is in an angular position relative to the frame corresponding to an assembly position.
En l'occurrence, l'élément de blocage 40 empêche la libération du charnon de tampon 22 du charnon de cadre 20 lorsque le tampon est dans une plage angulaire correspondant à la plage de positions d'assemblage. Cette plage de positions comprend la position d'ouverture à 90° et est limitée d'un côté par une première position intermédiaire PU dans laquelle le tampon 6 est ouvert de 80°environ, et de l'autre côté par une seconde position intermédiaire PI2 dans laquelle le tampon 6 est ouvert de 100° environ. Ces positions intermédiaires sont représentées en traits mixtes sur la figure 5.  In this case, the locking member 40 prevents the release of the buffer knuckle 22 from the frame knuckle 20 when the pad is in an angular range corresponding to the assembly position range. This range of positions comprises the open position at 90 ° and is limited on one side by a first intermediate position PU in which the buffer 6 is open by about 80 °, and on the other side by a second intermediate position PI2 wherein the buffer 6 is open by about 100 °. These intermediate positions are shown in phantom in Figure 5.
Par ailleurs, entre la position de fermeture et la première position intermédiaire PU et entre la seconde position intermédiaire PI2 et la position d'ouverture maximale, le désassemblage du charnon de tampon 22 du charnon de cadre 22 est empêché par les lèvres de retenue formant butées de blocage 30, 32. Les lèvres de retenue 30, 32 forment de ce fait des moyens de blocage complémentaires.  Furthermore, between the closed position and the first intermediate position PU and between the second intermediate position PI2 and the maximum open position, the disassembly of the buffer knuckle 22 of the frame knuckle 22 is prevented by the retaining lips forming stops. 30, 32. The retaining lips 30, 32 thus form complementary locking means.
Ainsi, le désassemblage est empêché dans toutes les positions angulaires que le tampon 6 peut prendre par rapport au cadre 4. Il en résulte une sécurité contre le vol du tampon ou contre son retrait par des personnes non autorisées.  Thus, the disassembly is prevented in all the angular positions that the buffer 6 can take with respect to the frame 4. This results in a security against the theft of the stamp or against its withdrawal by unauthorized persons.
Comme ceci est montré sur la figure 4, le charnon de tampon 22 comporte une ouverture 42, en l'occurrence un perçage cylindrique. Le charnon de tampon 22 comporte une surface 44 dans laquelle l'ouverture 42 est ménagée. Cette surface 44 est plane et, à l'état fermé du dispositif de voirie 2, est disposée parallèlement au plan du cadre PC et orientée vers l'ouverture d'assemblage 28 du cadre. Ainsi, l'ouverture 42 peut être facilement fabriquée par perçage.  As shown in Figure 4, the buffer knuckle 22 has an opening 42, in this case a cylindrical bore. The buffer knuckle 22 has a surface 44 in which the opening 42 is formed. This surface 44 is flat and, in the closed state of the road device 2, is arranged parallel to the plane of the PC frame and oriented towards the assembly opening 28 of the frame. Thus, the opening 42 can be easily manufactured by drilling.
L'élément de blocage 40 définit un sens d'introduction SI dans l'ouverture 42. Dans le cas présent, le sens d'introduction SI est dirigé perpendiculairement par rapport au plan de tampon PT et vers la surface 44. L'élément de blocage 40 comprend un corps 46 et une tête 48. L'élément de blocage 40 a une forme de révolution autour d'un axe d'élément de blocage AEB. Le corps 46 est cylindrique à section circulaire. La tête 48 a une forme de tronc de cône ou éventuellement une forme de cône. Ainsi, l'élément de blocage 40 est facile à fabriquer. The blocking element 40 defines an insertion direction S1 in the opening 42. In the present case, the insertion direction S1 is directed perpendicularly with respect to the buffer plane PT and towards the surface 44. The locking member 40 comprises a body 46 and a head 48. The locking member 40 has a shape of revolution about a locking member axis AEB. The body 46 is cylindrical with a circular section. The head 48 has a truncated cone shape or possibly a cone shape. Thus, the locking member 40 is easy to manufacture.
La dimension de la tête 48 est telle que la tête vient en butée contre une lèvre de retenue 32 du cadre lors de toute tentative de retrait du charnon de tampon 22 à partir d'une position du tampon comprise dans la plage angulaire de positions d'assemblage.  The size of the head 48 is such that the head abuts against a retaining lip 32 of the frame during any attempt to remove the buffer knuckle 22 from a position of the buffer included in the angular range of positions of assembly.
L'élément de blocage 40 et le charnon de tampon 22 ont aussi une butée s'opposant à un déplacement de l'élément de blocage dans le sens d'introduction SI. Dans le cas présent, cette butée est constituée par la surface 44 et par un épaulement 50 délimité par la tête 48 et le corps 46.  The blocking member 40 and the buffer knuckle 22 also have an abutment opposing a displacement of the blocking member in the SI insertion direction. In the present case, this stop is formed by the surface 44 and by a shoulder 50 delimited by the head 48 and the body 46.
De préférence, le corps 46 de l'élément de blocage 40 est inséré dans l'ouverture 42 à ajustement serré, l'élément de blocage 40 formant par exemple un rivet enfoncé dans l'ouverture 42. De plus, une colle peut être disposée entre le corps 46 et l'ouverture 42.  Preferably, the body 46 of the locking element 40 is inserted into the aperture 42 with a tight fit, the locking element 40 forming for example a rivet pressed into the opening 42. In addition, an adhesive can be arranged between the body 46 and the opening 42.
Par ailleurs, la tête 48 est dépourvue de contre-dépouille dans le sens opposé au sens d'introduction SI. Ainsi, la tête 48 est difficile à prendre par un outil lors d'une tentative d'extraction de l'élément de blocage 40 hors de l'ouverture 42. Dans le cas présent ceci est obtenu par la forme de tronc de cône de la tête 48 se rétrécissant dans le sens opposé au sens d'introduction.  Furthermore, the head 48 is free of undercut in the opposite direction to SI introduction. Thus, the head 48 is difficult to take by a tool during an attempt to extract the locking element 40 from the opening 42. In this case this is obtained by the truncated cone shape of the head 48 narrowing in the opposite direction to the direction of introduction.
En variante, d'autres formes peuvent être envisagées pour la tête, telle qu'une hémisphère.  Alternatively, other shapes may be envisaged for the head, such as a hemisphere.
Le dispositif de voirie est fabriqué comme suit.  The road system is manufactured as follows.
Tout d'abord le cadre 4 et le tampon 6 sont fabriqués et le charnon de tampon 22 est inséré dans le charnon de cadre 20 dans la position d'assemblage.  First, the frame 4 and the pad 6 are made and the paddle knuckle 22 is inserted into the frame hinge 20 in the assembly position.
Ensuite, le tampon est amené dans la position de fermeture.  Then, the buffer is brought into the closed position.
Puis, l'ouverture 42 est pratiquée dans le charnon de tampon 22.  Then, the opening 42 is made in the buffer knuckle 22.
Ensuite, l'élément de blocage 40 est introduit à force dans l'ouverture 42 jusqu'à ce que l'épaulement 50 touche la surface 44.  Then, the blocking member 40 is forced into the opening 42 until the shoulder 50 touches the surface 44.
L'élément de blocage 40 décrit a les avantages suivants :  The locking element 40 described has the following advantages:
- il rend le tampon difficile à voler.  - It makes the buffer difficult to steal.
- il permet au dispositif de voirie de conserver ses fonctionnalités, notamment en ce qui concerne l'articulation du tampon par rapport au cadre entre les positions de fermeture et d'ouverture maximale ainsi que la possibilité de verrouiller le tampon dans la position d'ouverture à 90° afin qu'il ne puisse pas se refermer accidentellement à partir de cette position de sécurité. - il se pose en peu de temps. it enables the road device to retain its functionalities, in particular as regards the articulation of the buffer with respect to the frame between the closed and the maximum opening positions, as well as the possibility of locking the buffer in the open position at 90 ° so that it can not be closed accidentally from this safety position. - it arises in a short time.
- il peut être posé sur un regard neuf aussi bien que sur regard ancien mais toujours après scellement du cadre.  - It can be placed on a new look as well as on old look but always after sealing of the frame.
Avantageusement, le dispositif de voirie selon l'invention comprend deux éléments de blocage 40 disposés symétriquement par rapport à un plan médian perpendiculaire à l'axe de charnon de tampon.  Advantageously, the road device according to the invention comprises two locking elements 40 arranged symmetrically with respect to a median plane perpendicular to the axis of knuckle buffer.
