Les Figures 1 et 2 représentent un regard d'accès selon l'invention, qui est désigné par la référence générale 10 et qui est par exemple un regard d'accès à une chambre technique souterraine renfermant des équipements de télécommunications.The Figures 1 and 2 represent an access view according to the invention, which is designated by the general reference 10 and which is for example a view of access to an underground technical chamber containing telecommunications equipment.

Le regard d'accès 10 comprend un cadre 12 et deux tampons 14.The access point 10 comprises a frame 12 and two buffers 14.

Le cadre 12 est scellé dans le sol et délimite une ouverture d'accès 16 (Figure 10), par exemple à une chambre souterraine comprenant des câbles de télécommunication. Dans le cas présent, l'ouverture d'accès 16 est en forme de carré.The frame 12 is sealed in the ground and delimits an access opening 16 ( Figure 10 ), for example to an underground chamber comprising telecommunication cables. In this case, the access opening 16 is in the form of a square.

Le regard 10 définit un plan de regard P-P qui s'étend sensiblement parallèlement au sol lors de l'installation.The view 10 defines a P-P viewing plane that extends substantially parallel to the ground during installation.

Le regard 10 définit un côté extérieur E et un côté intérieur I. Le regard 10 délimite également un axe central X-X s'étendant perpendiculairement au plan de regard P-P Dans ce qui suit, l'expression « périphérique » désigne le sens s'éloignant radialement de l'axe X-X et « central » désigne le sens se rapprochant de l'axe X-X.The eye 10 defines an outer side E and an inner side I. The eye 10 also defines a central axis XX extending perpendicularly to the viewing plane PP In what follows, the expression "peripheral" designates the direction moving radially away from the axis XX and "central" means the approaching direction. of the XX axis.

Par ailleurs, le regard 10 comporte pour chaque tampon 14 une charnière (non visible) adaptée pour faire basculer le tampon concerné autour d'un axe de charnière Y-Y entre des positions fermée (Figure 1), intermédiaire (Figure 10), d'ouverture à 90° (Figure 11) et d'ouverture maximale (Figure 12).Furthermore, the eye 10 comprises for each buffer 14 a hinge (not visible) adapted to tilt the concerned buffer around a hinge axis YY between closed positions ( Figure 1 ), intermediate ( Figure 10 ), opening at 90 ° ( Figure 11 ) and maximum opening ( Figure 12 ).

Le cadre 12 comporte une paroi de cadre 18 s'étendant sensiblement perpendiculairement au plan de regard P-P.The frame 12 has a frame wall 18 extending substantially perpendicularly to the viewing plane P-P.

Le cadre 12 comporte une base de cadre 20 s'étendant parallèlement au plan de regard P-P, et faisant saillie radialement vers l'intérieur et vers l'extérieur de la paroi de cadre 18. Cette base de cadre 20 est destinée à être noyée dans un matériau de scellement, tel que du mortier.The frame 12 comprises a frame base 20 extending parallel to the viewing plane PP, and protruding radially inwards and outwards from the frame wall 18. This frame base 20 is intended to be embedded in a sealing material, such as mortar.

Chaque tampon 14 comprend un corps de base générique 22 sensiblement en forme de triangle, qui couvre environ la moitié de la surface de l'ouverture d'accès 16 et qui s'étend suivant un plan de tampon T-T, qui est parallèle au plan de la Figure 1.Each pad 14 comprises a substantially triangular-shaped generic base body 22, which covers about half of the area of the access opening 16 and which extends along a buffer plane TT, which is parallel to the plane of the Figure 1 .

Dans la position fermée, le plan de tampon T-T s'étend parallèlement au plan de regard P-P. Dans la position intermédiaire, le plan de tampon T-T s'étend obliquement par rapport au plan de regard P-P, par exemple selon un angle compris entre 30° et 75°. Dans la position d'ouverture à 90°, le plan de tampon T-T s'étend à 90° par rapport au plan de regard P-P. Dans la position d'ouverture maximale, le plan de tampon T-T s'étend selon un angle supérieur à 90° par rapport à la position fermée, par exemple suivant un angle compris entre 100° et 110°.In the closed position, the T-T buffer plane extends parallel to the P-P look plane. In the intermediate position, the T-T buffer plane extends obliquely relative to the viewing plane P-P, for example at an angle of between 30 ° and 75 °. In the 90 ° open position, the T-T buffer plane extends at 90 ° to the P-P viewing plane. In the maximum open position, the T-T buffer plane extends at an angle greater than 90 ° with respect to the closed position, for example at an angle of between 100 ° and 110 °.

Le corps de base 22 est identique pour chaque tampon 14. Par conséquent, un seul corps de base 22 sera décrit par la suite.The base body 22 is identical for each pad 14. Therefore, only one base body 22 will be described later.

Le corps de base 22 est fabriqué d'une seule pièce par moulage, de préférence en fonte.The base body 22 is made in one piece by molding, preferably cast iron.

Le corps de base 22 comprend une surface intérieure 24, visible sur la Figure 2, et une surface extérieure 26 (Figure 10). Les deux surfaces intérieure 24 et extérieure 26 sont parallèles au plan de tampon T-T. La surface intérieure 24 correspond à un côté intérieur du tampon 14 tandis que la surface extérieure 26 correspond à un côté extérieur du tampon 14.The base body 22 comprises an inner surface 24, visible on the Figure 2 , and an outer surface 26 ( Figure 10 ). The two inner 24 and outer 26 surfaces are parallel to the buffer plane TT. The inner surface 24 corresponds to an inner side of the pad 14 while the outer surface 26 corresponds to an outer side of the pad 14.

Le corps de base 22 est muni de nervures de rigidification 28 sur sa surface intérieure 24.The base body 22 is provided with stiffening ribs 28 on its inner surface 24.

Le corps de base 22 comporte une zone de manoeuvre 30 adaptée pour recevoir un outil de manoeuvre (non représenté) destiné à manoeuvrer le tampon 14 lors de son soulèvement par pivotement autour de l'axe de charnière Y-Y. Cette zone 30 est également adaptée pour verrouiller le tampon 14 par rapport au cadre ou pour sécuriser le tampon 14 par rapport au tampon adjacent. En outre, le corps de base 22 comporte une zone de sécurisation 32 adaptée pour sécuriser le tampon 14 par rapport au cadre 12.The base body 22 comprises an operating zone 30 adapted to receive an operating tool (not shown) for manipulating the buffer 14 during its lifting by pivoting about the hinge axis YY. This zone 30 is also adapted to lock the buffer 14 relative to the frame or to secure the buffer 14 relative to the adjacent buffer. In addition, the base body 22 comprises a securing zone 32 adapted to secure the buffer 14 with respect to the frame 12.

Le corps de base 22 est muni d'une zone de réception 34 adaptée pour recevoir une attache de fixation 36 d'un accessoire 38 sur le tampon 14 comme cela sera expliqué plus en détail par la suite.The base body 22 is provided with a receiving zone 34 adapted to receive a fastening clip 36 of an accessory 38 on the pad 14 as will be explained in more detail later.

La zone de réception 34 est formée par un évidement de réception 40, de forme sensiblement oblongue, ménagé dans le corps de base 22 et traversant le corps de base 22. L'évidement de réception 40 est une ouverture traversante.The receiving zone 34 is formed by a substantially oblong receiving recess 40 formed in the base body 22 and passing through the base body 22. The receiving recess 40 is a through aperture.

Lors de la fabrication du corps de base 22, les évidements de réception 40 ne sont pas nécessairement créés. Lorsque ces évidements de réception 40 ne sont pas ménagés dans le corps de base 22 lors de sa fabrication, chaque emplacement prévu pour les évidements de réception 40 est recouvert par une portion de recouvrement amovible 42, de forme sensiblement identique à celle de l'évidement 40, qui est fixée par au moins une portion frangible 44 au corps de base 22.In the manufacture of the base body 22, the receiving recesses 40 are not necessarily created. When these receiving recesses 40 are not formed in the base body 22 during its manufacture, each location provided for the receiving recesses 40 is covered by a removable covering portion 42, of substantially identical shape to that of the recess. 40, which is fixed by at least one frangible portion 44 to the base body 22.

Avantageusement, la portion de recouvrement 42 et la portion frangible 44 sont fabriquées d'une seule pièce avec le corps de base 22.Advantageously, the covering portion 42 and the frangible portion 44 are made in one piece with the base body 22.

Par exemple, la portion de recouvrement 42 est reliée au corps de base 22 par trois portions frangibles 44 formées par des ponts de matière.For example, the covering portion 42 is connected to the base body 22 by three frangible portions 44 formed by material bridges.

Ainsi, lorsque le tampon 14 est mis en place dans le cadre 12, les portions de recouvrement 42 permettent de limiter la pénétration, par les évidements de réception 40, d'eaux pluviales ou de détritus divers à l'intérieur I du regard 10.Thus, when the pad 14 is placed in the frame 12, the cover portions 42 serve to limit the penetration by the receiving recesses 40, or of other stormwater litter within I to 10 look.

Afin de faciliter le basculement des tampons 14 autour de leur axe de charnière Y-Y, le regard d'accès 10 comprend, pour chaque tampon 14, un vérin 38 d'aide au soulèvement du tampon 14 et une attache de fixation 36 du vérin 38 sur le tampon 14. Le regard d'accès 10 illustré sur les figures comprend donc deux vérins 38(Figure 2).In order to facilitate the tilting of the pads 14 around their hinge axis YY, the access point 10 comprises, for each pad 14, a jack 38 for lifting the pad 14 and a fastening clip 36 for the jack 38 on the buffer 14. The access port 10 illustrated in the figures thus comprises two cylinders 38 ( Figure 2 ).

Chaque vérin 38 est fixé par l'une de ses extrémités 46 à la paroi de cadre 18 et par son autre extrémité 48 à l'attache de fixation 36 correspondante, et ce au moyen d'organes de fixation 50. L'organe de fixation 50 est par exemple une goupille. L'extrémité 46 est fixée à la paroi de cadre 18 au moyen d'une articulation autour d'un axe d'articulation A-A, tandis que l'extrémité 48 est fixée à l'attache 36 au moyen d'une articulation autour d'un axe d'articulation B-B.Each jack 38 is fixed at one of its ends 46 to the frame wall 18 and at its other end 48 to the corresponding fastener 36, and this by means of fasteners 50. The fastener 50 is for example a pin. The end 46 is fixed to the frame wall 18 by means of a hinge about a hinge axis AA, while the end 48 is fixed to the hinge 36 by means of a hinge around a hinge axis BB.

L'axe d'articulation A-A est parallèle au plan de regard P-P. L'axe d'articulation B-B est parallèle au plan de tampon T-T. De plus, les axes d'articulation A-A et B-B sont parallèles l'un à l'autre, et à l'axe de charnière Y-Y.The hinge axis A-A is parallel to the plane of view P-P. The hinge axis B-B is parallel to the T-T buffer plane. In addition, the hinge pins A-A and B-B are parallel to each other, and to the hinge axis Y-Y.

Les vérins 38 sont des vérins à gaz et ne seront donc pas décrits plus en détail par la suite. En variante, le vérin 38 à gaz peut être remplacé par un autre élément de poussée, tel qu'un ressort.The cylinders 38 are gas cylinders and will therefore not be described in more detail later. Alternatively, the gas cylinder 38 may be replaced by another thrust element, such as a spring.

Comme illustré sur les Figures 3 et 4, chaque attache de fixation 36 est sensiblement en forme de L ayant deux ailes, dont une aile courte 52 et une aile longue 54.As illustrated on Figures 3 and 4 each fastener 36 is substantially L-shaped having two wings, including a short wing 52 and a long wing 54.

L'attache de fixation 36 comprend un moyen de fixation ou de blocage 56 formé ici par un orifice de fixation 57 ménagé dans l'aile longue 54, à proximité d'une extrémité libre 58 de l'aile longue.The fixing clip 36 comprises a fixing or blocking means 56 formed here by a fixing orifice 57 formed in the long wing 54, near a free end 58 of the long wing.

L'orifice de fixation 57 est adapté pour recevoir un des organes de fixation 50 pour la fixation du vérin 38 sur le tampon 14.The fixing orifice 57 is adapted to receive one of the fasteners 50 for fastening the jack 38 to the pad 14.

L'attache de fixation 36 est munie d'un pied de retenue 60 adapté pour relier de manière amovible l'attache de fixation 36 au tampon 14 à travers l'évidement de réception 40 par une liaison par complémentarité de formes. Le pied de retenue 60 s'étend selon un axe de pied C-C.The fastener 36 is provided with a retaining foot 60 adapted to releasably connect the fastener 36 to the pad 14 through the receiving recess 40 by a complementary fit of shapes. The retaining foot 60 extends along a foot axis C-C.

Le pied de retenue 60 a une base 61 de forme cylindrique d'axe C-C.The retaining foot 60 has a cylindrical base 61 of axis C-C.

Le pied de retenue 60 est fixé sur l'aile courte 52 et comporte au moins un bras de fixation 62 adapté pour coopérer par complémentarité de formes avec le tampon 14. Ici, le pied de retenue 60 comporte deux bras 62 s'étendant chacun sensiblement perpendiculairement par rapport à la base 61 du pied de retenue 60, et dans le prolongement l'un de l'autre pour ne former qu'une seule pièce 64.The retaining foot 60 is fixed on the short wing 52 and comprises at least one attachment arm 62 adapted to cooperate in complementary form with the buffer 14. Here, the retaining foot 60 comprises two arms 62 each extending substantially perpendicular to the base 61 of the retaining foot 60, and in the extension of one another to form a single piece 64.

Les deux bras 62 sont disposés sur l'extrémité de la base 61 opposée à l'aile courte 52.The two arms 62 are arranged on the end of the base 61 opposite to the short wing 52.

La pièce 64 possède une forme sensiblement identique à celle de l'évidement de réception 40 et la fixation entre l'attache 36 et le tampon 14 est de type baïonnette.The piece 64 has a shape substantially identical to that of the receiving recess 40 and the attachment between the fastener 36 and the pad 14 is of the bayonet type.

L'attache de fixation 36 et le tampon 14 peuvent ainsi adopter une configuration de retenue, dans laquelle l'attache de fixation 36 est engagée dans l'évidement de réception 40 et retenue dans celui-ci par le pied de retenue 60, et une configuration de libération, dans laquelle le pied de retenue 60 de l'attache 36 est retirable de l'évidement de réception 40 ou insérable dans celui-ci.The fastener 36 and the pad 14 can thus adopt a retaining configuration, in which the fastener 36 is engaged in the receiving recess 40 and retained therein by the retaining foot 60, and a release configuration, wherein the retaining foot 60 of the fastener 36 is removable from the accommodating recess 40 or insertable therein.

Dans la configuration de retenue, les bras de fixation 62 sont décalés angulairement par rapport à l'évidement de réception 40 autour de l'axe de pied C-C et chevauchent le corps de base 22.In the retaining configuration, the attachment arms 62 are angularly offset relative to the receiving recess 40 about the foot axis C-C and overlap the base body 22.

Dans la configuration de libération, les bras de fixation 62 sont alignés avec l'évidement de réception 40. Ainsi, le pied de retenue 60 est insérable dans l'évidement de réception 40 et retirable de celui-ci par un déplacement selon l'axe de pied C-C.In the release configuration, the attachment arms 62 are aligned with the receiving recess 40. Thus, the retaining foot 60 is insertable into the receiving recess 40 and removable therefrom by a displacement along the axis of foot CC.

Pendant ce déplacement, l'axe de pied C-C est sensiblement perpendiculaire au plan de tampon T-T.During this movement, the foot axis CC is substantially perpendicular to the buffer plane TT.

L'attache 36 comporte un emporte-pièce 65 adapté pour pratiquer l'évidement de réception 40 dans le corps de base 22 du tampon 14.The fastener 36 comprises a punch 65 adapted to practice the receiving recess 40 in the base body 22 of the buffer 14.

L'emporte-pièce présente une surface de frappe 67 dont la forme est sensiblement identique à la forme de la portion de recouvrement 42.The punch has a striking surface 67 whose shape is substantially identical to the shape of the covering portion 42.

Dans l'exemple décrit ici, l'emporte-pièce 65 est formé par le pied de retenue 60, la surface de frappe 67 étant formée par la surface externe 66 de la pièce 64.In the example described here, the punch 65 is formed by the retaining foot 60, the striking surface 67 being formed by the outer surface 66 of the workpiece 64.

Dans la configuration de retenue de l'attache de fixation 36, l'attache 36 est adaptée pour osciller par rapport au tampon 14 entre deux positions de butée.In the retaining configuration of the fastener 36, the fastener 36 is adapted to oscillate with respect to the pad 14 between two stop positions.

Pour cela, l'attache de fixation 36 comprend une base d'attache 68 solidaire du pied de retenue 60 et s'étendant sensiblement perpendiculairement par rapport au pied de retenue 60.For this, the fastening clip 36 comprises an attachment base 68 integral with the retaining foot 60 and extending substantially perpendicular to the retaining foot 60.

La base d'attache 68 est de forme allongée et disposée entre l'aile courte 52 et le pied de retenue 60.The attachment base 68 is of elongated shape and disposed between the short wing 52 and the retaining foot 60.

La base d'attache 68 possède deux butées 70 opposées et adaptées chacune à entrer en contact avec le tampon 14 dans l'une des positions de butée.The attachment base 68 has two stops 70 opposite and each adapted to come into contact with the buffer 14 in one of the abutment positions.

L'attache 36 possède une liberté d'oscillation sensiblement comprise entre 5° et 15°. La liberté d'oscillation est une liberté autour d'un axe d'oscillation s'étendant parallèlement à l'axe de charnière Y-Y.The fastener 36 has a freedom of oscillation substantially between 5 ° and 15 °. Freedom of oscillation is freedom around an axis of oscillation extending parallel to the Y-Y hinge axis.

L'attache de fixation 36 est réalisée d'une seule pièce et fabriquée à partir de métal, notamment de fonte.The fastener 36 is made in one piece and made of metal, including cast iron.

Le procédé de fixation du vérin 38 sur le tampon 14 est expliqué ci-après.The method of fixing the jack 38 to the pad 14 is explained below.

Une première étape de ce procédé consiste à pratiquer l'évidement de réception 40.A first step of this method consists in practicing the reception recess 40.

Pour cela, l'attache de fixation 36 est posée sur le tampon 14 en superposant la surface de frappe 67 de l'emporte-pièce 65 avec la portion de recouvrement 42 (Figure 5).For this, the fixing clip 36 is placed on the pad 14 by superimposing the striking surface 67 of the punch 65 with the covering portion 42 (FIG. Figure 5 ).

Ceci peut être effectué lorsque le tampon 14 est dans sa position fermée. De plus, la surface de frappe 67 est avantageusement posée sur le côté extérieur de la portion de recouvrement 42.This can be done when the tampon 14 is in its closed position. In addition, the striking surface 67 is advantageously placed on the outer side of the covering portion 42.

A l'aide d'un outil, par exemple un marteau 72, l'utilisateur frappe sur l'aile courte 52 de l'attache de fixation 36 de manière à rompre les portions frangibles 44 et libérer ainsi les évidements de réception 40.With the aid of a tool, for example a hammer 72, the user strikes the short flange 52 of the fastener 36 so as to break the frangible portions 44 and thus release the receiving recesses 40.

Lors d'une deuxième étape du procédé (Figure 6), les bras 62 sont alignés avec l'évidement 40 et le pied de retenue 60 est inséré dans l'évidement de réception 40, du côté intérieur au tampon 14. Cette insertion est effectuée le long de l'axe de pied C-C et perpendiculairement au plan de tampon T-T.In a second step of the process ( Figure 6 ), the arms 62 are aligned with the recess 40 and the retaining foot 60 is inserted into the receiving recess 40, on the inside of the pad 14. This insertion is performed along the foot axis CC and perpendicularly to the buffer plane TT.

Une fois insérés, les bras 62 se trouvent du côté extérieur du tampon 14.Once inserted, the arms 62 are on the outside of the pad 14.

Le tampon 14 et l'attache de fixation 36 se trouvent alors dans la configuration de libération.The buffer 14 and the fastener 36 are then in the release configuration.

Dans cette configuration, l'aile courte 52 s'étend parallèlement à l'axe de charnière Y-Y.In this configuration, the short wing 52 extends parallel to the Y-Y hinge axis.

Ensuite, comme représenté sur la Figure 7, l'attache de fixation 36 est tournée dans le sens de la flèche F (sens anti-horaire sur la Figure 7) autour de l'axe de pied C-C et ce jusqu'à ce que l'aile courte 52 de l'attache de fixation 36 soit dirigée vers l'axe de charnière Y-Y associé et s'étende perpendiculairement à cet axe de charnière (Figure 8). Dans cette position, l'attache de fixation 36 et le tampon 14 sont dans leur configuration de retenue.Then, as shown on the Figure 7 the fixing clip 36 is rotated in the direction of the arrow F (counter-clockwise on the Figure 7 ) about the foot axis CC until the short flange 52 of the fastener 36 is directed towards the associated hinge axis YY and extends perpendicularly to this hinge axis ( Figure 8 ). In this position, the fastener 36 and the pad 14 are in their retaining configuration.

Il suffit alors à l'utilisateur de fixer le vérin 38 à l'attache 36 à l'aide de l'organe de fixation 50 et du moyen de fixation 56. La liberté de basculement de l'attache 36 autour de l'axe d'oscillation rend aisé l'alignement du moyen de fixation 56 et de l'extrémité du vérin.It then suffices for the user to fix the jack 38 to the fastener 36 with the aid of the fastener 50 and the fastening means 56. The freedom of tilting of the fastener 36 around the axis of oscillation makes easy the alignment of the fixing means 56 and the end of the jack.

Le vérin 38 est ainsi fixé au tampon 14 (Figure 9) et empêche alors l'attache 36 de pivoter autour de l'axe C-C dans le sens tendant à amener l'attache 36 dans la configuration de libération.The jack 38 is thus fixed to the pad 14 ( Figure 9 ) and then prevents the fastener 36 from pivoting about the axis CC in the direction tending to bring the fastener 36 into the release configuration.

En référence aux Figures 10 à 12, lors du basculement du tampon 14, l'attache 36 se trouve dans l'une ou l'autre de ses positions de butée, en fonction de la course du vérin 38.With reference to Figures 10 to 12 during the tilting of the buffer 14, the fastener 36 is in one or other of its abutment positions, as a function of the stroke of the jack 38.

En particulier, entre la position fermée et la position d'ouverture à 90°, le vérin 38 pousse l'attache 36 dans l'une des positions de butée. Au-delà de 90°, le vérin 38 ne pousse plus, mais grâce à sa liberté d'oscillation l'attache 36 bascule vers l'autre position de butée, permettant ainsi au tampon 14 d'atteindre la position d'ouverture maximale. Entre la position d'ouverture à 90° et la position d'ouverture maximale du tampon, le vérin 38 est donc dans une configuration détende.In particular, between the closed position and the 90 ° open position, the cylinder 38 pushes the fastener 36 into one of the abutment positions. Beyond 90 °, the cylinder 38 no longer pushes, but thanks to its freedom of oscillation the fastener 36 switches to the other stop position, thus allowing the pad 14 to reach the maximum open position. Between the open position at 90 ° and the maximum open position of the buffer, the cylinder 38 is therefore in a detent configuration.

L'invention propose donc un dispositif de voirie muni d'une attache simple et économique à réaliser, qui facilite la fixation d'un accessoire sur le dispositif de voirie.The invention therefore provides a road device with a simple and economical fastener to achieve, which facilitates the attachment of an accessory on the road device.

La liberté d'oscillation de l'attache 36 permet un montage facile, rapide, sans effort et non dangereux du vérin.The freedom of oscillation of the fastener 36 allows an easy, fast, effortless and non-dangerous mounting of the jack.

De plus, cette liberté d'oscillation permet également de limiter les contraintes exercées sur le vérin 38, notamment en fin de course, ce qui augmente la fiabilité et la durée de vie du vérin 38.In addition, this freedom of oscillation also makes it possible to limit the stresses exerted on the jack 38, particularly at the end of the stroke, which increases the reliability and the service life of the jack 38.

En outre, le choix laissé à l'utilisateur de monter ou non le vérin permet non seulement au fabricant de produire des tampons standards mais également de les conditionner, stocker et transporter plus facilement en les empilant.In addition, the choice left to the user to mount or not the cylinder not only allows the manufacturer to produce standard pads but also to package, store and transport more easily by stacking.

Aussi, le vérin 38, lorsqu'il est relié à l'attache 36 et au cadre, s'oppose à une rotation de l'attache de sa configuration de retenue vers sa configuration de libération. Le vérin est donc un moyen d'arrêt en rotation de l'attache 36.Also, the cylinder 38, when connected to the fastener 36 and the frame, opposes rotation of the fastener from its retaining configuration to its release configuration. The jack is therefore a means for stopping the rotation of the fastener 36.

Les caractéristiques de l'invention ont été décrites en référence à un regard d'accès tel que décrit dans les revendications, muni d'une attache pour la fixation d'un vérin.The features of the invention have been described with reference to an access point as described in the claims, provided with a fastener for fixing a jack.

L'invention s'applique également à la liaison d'autres élémens d'un dispositif de voirie tel que décrit dans les revendications.The invention is also applicable to the connection of other elements of a road device as described in the claims.

En variante, l'attache de fixation du dispositif revendiqué est une attache de sécurisation ayant un nez de blocage. Cette variante est montrée sur les Figures 13 à 18. Les différences par rapport aux Figures 1 à 12 sont décrites ci-après.Alternatively, the fastening clip of the claimed device is a securing clip having a locking nose. This variant is shown on the Figures 13 to 18 . Differences from Figures 1 to 12 are described below.

Les Figures 13 à 16 montrent diverses étapes de la mise en place d'une attache 36 sur un tampon 14, par complémentarité de formes du pied de retenue de l'attache avec l'évidement de réception ménagé dans le tampon 14.The Figures 13 to 16 show various stages of the establishment of a fastener 36 on a buffer 14, by complementarity of shapes of the fastener holding foot with the receiving recess in the buffer 14.

L'attache 36 est en outre adaptée pour bloquer le soulèvement du tampon 14 par rapport à un cadre (Figure 18).The fastener 36 is further adapted to block the lifting of the buffer 14 with respect to a frame ( Figure 18 ).

A cette fin, l'attache 36 comporte un nez de blocage 80 en tant que moyen de fixation 56 au cadre. Le nez de blocage 80 est adapté pour venir en butée contre le cadre lors d'une tentative de soulèvement du tampon.For this purpose, the fastener 36 has a locking nose 80 as fastening means 56 to the frame. The locking nose 80 is adapted to abut against the frame when attempting to lift the pad.

De plus, dans sa configuration de retenue, l'attache de fixation 36 est fixée au tampon, et ce sans liberté de basculement par rapport au tampon 14.In addition, in its retaining configuration, the fastening clip 36 is fixed to the pad, and this without freedom of tilting with respect to the pad 14.

L'ensemble comporte également des moyens d'arrêt adaptés pour s'opposer à la rotation de l'attache de fixation 36 hors de sa configuration de retenue. Les moyens d'arrêt comportent au moins un ergot 90 fixé au tampon, une saillie 92 fixée à l'attache 36 et munie d'une gorge de réception d'une goupille 94 (cf. Figure 16). En position d'arrêt, la goupille 94 est disposée entre l'ergot 90 et la saillie 92 et s'étend selon un axe de goupille qui est parallèle au nez de blocage 80. De plus, l'attache 36 comprend un évidement de passage 96 adapté pour permettre le passage de l'ergot 90 fixé au tampon lors de la rotation de l'attache 36 de sa position de libération dans sa position de retenue.The assembly also comprises stop means adapted to oppose the rotation of the fastener 36 out of its retaining configuration. The stop means comprise at least one lug 90 fixed to the buffer, a projection 92 fixed to the fastener 36 and provided with a groove for receiving a pin 94 (cf. Figure 16 ). In the off position, the pin 94 is disposed between the lug 90 and the projection 92 and extends along a pin axis which is parallel to the locking nose 80. In addition, the fastener 36 comprises a passage recess 96 adapted to allow the passage of the lug 90 fixed to the buffer during the rotation of the fastener 36 from its release position in its retaining position.

En variante non représentée, l'attache de fixation peut être une attache adaptée pour fixer une barre de blocage anti-vandalisme.Alternatively not shown, the fastener can be a fastener adapted to secure an anti-vandal blocking bar.

Le vérin peut également être remplacé par un autre élément de poussée, tel qu'un ressort par exemple.The cylinder can also be replaced by another thrust element, such as a spring for example.
