Description

La présente invention concerne un tampon pour un dispositif de voirie muni d'un cadre, le tampon étant du type comprenant

  • un organe de blocage,
  • un corps de base définissant une surface de recouvrement du dispositif de voirie, s'étendant selon un plan de tampon, et ayant un logement adapté pour recevoir l'organe de blocage,
ce logement et l'organe de blocage étant adaptés pour bloquer le tampon par rapport au cadre ou par rapport à un tampon voisin, lorsque l'organe de blocage se trouve dans le logement.The present invention relates to a buffer for a road device provided with a frame, the buffer being of the type comprising
  • a locking member,
  • a base body defining a covering surface of the road device, extending in a buffer plane, and having a housing adapted to receive the locking member,
this housing and the locking member being adapted to block the buffer relative to the frame or relative to a neighboring buffer, when the locking member is in the housing.

Elle s'applique notamment aux dispositifs de fermeture de chambres techniques d'inspection d'un réseau câblé souterrain, tels que des trappes, et aux dispositifs de fermeture de cheminées de visite ou d'inspection d'un réseau d'eaux souterrain, tels que des regards de chaussée ou de trottoirs.It applies in particular to the closing devices of technical inspection chambers of an underground cable network, such as hatches, and the closing devices for inspection chimneys or inspection of an underground water network, such as than manholes or sidewalks.

Elle s'applique plus particulièrement à la sécurisation des regards ou trappes d'accès pour des installations de télécommunications.It applies more particularly to securing manholes or access hatches for telecommunications installations.

Ces dispositifs de voirie comprennent généralement un cadre scellé durablement dans le sol, dans lequel sont insérés de manière libérable un ou plusieurs tampons, disposés au ras de la surface du sol.These road devices generally comprise a frame permanently sealed in the ground, in which are releasably inserted one or more buffers, arranged flush with the ground surface.

Dans le cas où le dispositif comporte plusieurs tampons, ces tampons sont soit un tampon dit esclave, soit un tampon dit maître. Un tampon maître peut être retiré du cadre indépendamment de la présence éventuelle de tampons esclaves, tandis qu'un tampon esclave ne peut être retiré du cadre lorsque le tampon maître est en place.In the case where the device comprises several buffers, these buffers are either a so-called slave buffer or a so-called master buffer. A master buffer can be removed from the frame regardless of the presence of slave buffers, while a slave buffer can not be removed from the frame when the master buffer is in place.

Le document FR-A-2 765 256 décrit un tampon universel pour un regard d'accès pour des chambres de raccordement.The document FR-A-2,765,256 describes a universal buffer for an access view for connecting chambers.

Le tampon comprend un corps de base qui comporte plusieurs saillies d'attachement auxquelles peuvent être fixés au choix des éléments fonctionnels, tels que des crochets ou une serrure afin de former soit un tampon esclave, soit un tampon maître.The stamp comprises a base body which has a plurality of attachment projections to which functional elements, such as hooks or locks, can be affixed in order to form either a slave buffer or a master buffer.

Chaque saillie d'attachement comprend des surfaces d'application des éléments fonctionnels qui sont inclinées l'une vers l'autre. Les éléments fonctionnels ont des surfaces inclinées de manière complémentaire de celles des saillies d'attachement. Les éléments fonctionnels doivent donc être fabriqués spécialement pour le tampon et sont de ce fait coûteux.Each attachment projection includes application surfaces of the functional elements that are inclined toward each other. The functional elements have surfaces inclined in a manner complementary to those of attachment projections. The functional elements must therefore be specially manufactured for the buffer and are therefore expensive.

De plus, les éléments fonctionnels sont fixés par vis sur les saillies d'attachement. Ce moyen de fixation est coûteux en temps de montage et en logistique car un grand nombre de composants doit être stocké. Par ailleurs, les vis peuvent se libérer de manière intempestive.In addition, the functional elements are fixed by screws on the attachment projections. This fixing means is expensive in assembly time and logistics because a large number of components must be stored. Moreover, the screws can be released unexpectedly.

Egalement, les éléments fonctionnels sont fixés sur des saillies d'attachement qui n'ont pas d'utilité lorsque aucun élément fonctionnel n'y est attaché. Le tampon est donc coûteux en matière.Also, the functional elements are attached to attachment projections which are of no use when no functional element is attached thereto. The buffer is therefore expensive in matter.

La présente invention a pour but de proposer un tampon qui permette une fixation fiable des éléments fonctionnels par des moyens simples et économiques.The object of the present invention is to propose a buffer which allows reliable fixing of the functional elements by simple and economical means.

D'autres buts de l'invention sont de proposer un tampon qui nécessite peu de matière et qui ait une dépense en logistique faible.Other objects of the invention are to provide a buffer that requires little material and has a low logistic expense.

Sur la Figure 1 est représenté un regard d'accès selon l'invention, désigné par la référence générale 2.On the Figure 1 is represented an access view according to the invention, designated by the general reference 2.

Le regard d'accès 2 est par exemple un regard d'accès à une chambre technique souterraine renfermant des équipements de télécommunication.The access window 2 is for example a view of access to an underground technical chamber containing telecommunication equipment.

Le regard d'accès 2 comprend un cadre 4, un tampon esclave 6 et un tampon maître 8.The access window 2 comprises a frame 4, a slave buffer 6 and a master buffer 8.

Le cadre 4 est scellé dans le sol et délimite une ouverture d'accès 10 (Figure 6), par exemple à une chambre souterraine comprenant des câbles de télécommunication. Dans le cas présent, l'ouverture d'accès 10 est en forme de carré.The frame 4 is sealed in the ground and delimits an access opening 10 ( Figure 6 ), for example to an underground chamber comprising telecommunication cables. In this case, the access opening 10 is square.

Le regard 2 définit un plan de regard P-P qui s'étend sensiblement parallèlement au sol lors de l'installation.The view 2 defines a P-P viewing plane that extends substantially parallel to the ground during installation.

Le regard 2 définit un côté extérieur E et un côté intérieur I. Le regard 2 délimite également un axe central X-X s'étendant perpendiculairement au plan de regard P-P.The view 2 defines an outer side E and an inner side I. The eye 2 also defines a central axis XX extending perpendicular to the viewing plane PP.

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 central X-X.In what follows, the term "peripheral" designates the direction moving radially away from the axis X-X and "central" means the direction approximating the central axis X-X.

Par ailleurs, le regard 2 comporte pour chaque tampon 6, 8 une charnière (non visible) adaptée pour faire basculer le tampon concerné autour d'un axe de charnière Y-Y entre des positions ouvertes et fermées.Furthermore, the view 2 comprises for each buffer 6, 8 a hinge (not visible) adapted to rock the concerned buffer around a Y-Y hinge axis between open and closed positions.

Le cadre 4 comporte une paroi de cadre 12 s'étendant sensiblement perpendiculairement au plan de regard P-P.The frame 4 comprises a frame wall 12 extending substantially perpendicular to the P-P viewing plane.

Le cadre comporte une base de cadre 14 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 12. Cette base de cadre est destinée à être noyée dans un matériau de scellement tel que du mortier.The frame comprises a frame base 14 extending parallel to the viewing plane PP, and protruding radially inwards and outwards from the frame wall 12. This frame base is intended to be embedded in a material sealing material such as mortar.

Le tampon maître 8 peut être mis en place et retiré du cadre 4 indépendamment de la présence d'un tampon esclave 6, tandis que le tampon esclave 6 ne peut être retiré du cadre 4, ni installé dans celui-ci, lorsque le tampon maître 8 est en place. Ainsi, après mise en place du tampon esclave 6, il suffit de verrouiller le tampon maître 8 par rapport au cadre pour verrouiller le tampon esclave 6 dans le cadre 4.The master buffer 8 can be put in place and removed from the frame 4 independently of the presence of a slave buffer 6, while the slave buffer 6 can not be removed from the frame 4, nor installed therein, when the master buffer 8 is in place. Thus, after placing the slave buffer 6, it suffices to lock the master buffer 8 with respect to the frame to lock the slave buffer 6 in the frame 4.

Chaque tampon 6, 8 comprend un corps de base générique 16 sensiblement en forme de triangle, qui couvre environ la moitié de la surface de l'ouverture d'accès 10 et qui s'étend suivant un plan de tampon T-T, qui est parallèle au plan de la Figure 3.Each pad 6, 8 comprises a substantially triangle-shaped generic base body 16, which covers about half of the area of the access opening 10 and which extends along a buffer plane TT, which is parallel to the plan of the Figure 3 .

Le corps de base 16 est identique pour chacun des tampons esclave 6 ou maître 8. Par conséquent, un seul corps de base 16 sera décrit par la suite.The base body 16 is identical for each of the slave buffer 6 or master 8. Therefore, a single base body 16 will be described later.

Le corps de base 16 est fabriqué d'une seule pièce par moulage, de préférence en fonte.The base body 16 is made in one piece by molding, preferably cast iron.

Le corps de base 16 comprend une surface intérieure 18, visible sur la Figure 2, et une surface extérieure 20. Les deux surfaces 18, 20 sont parallèles au plan de tampon T-T. La surface intérieure 18 correspond à un côté intérieur du tampon 6, 8 tandis que la surface extérieure 20 correspond à un côté extérieur du tampon 6, 8.The base body 16 comprises an inner surface 18, visible on the Figure 2 , and an outer surface 20. The two surfaces 18, 20 are parallel to the buffer plane TT. The inner surface 18 corresponds to an inner side of the pad 6, 8 while the outer surface 20 corresponds to an outer side of the pad 6, 8.

Le corps de base 16 comporte des nervures de rigidification 24 sur sa surface intérieure 18. En outre, le corps de base 16 comporte des évidements de manoeuvre 26 débouchant sur la surface extérieure 20. Chaque évidement de manoeuvre 26 est adapté pour recevoir un outil de manoeuvre (non représenté) destiné à manoeuvrer le tampon 6, 8 lors de son soulèvement ou de son retrait du cadre.The base body 16 has stiffening ribs 24 on its inner surface 18. In addition, the base body 16 has operating recesses 26 opening on the outer surface 20. Each operating recess 26 is adapted to receive a tool maneuver (not shown) for manipulating the buffer 6, 8 during its lifting or removal from the frame.

La surface intérieure 18 du corps de base 16 comporte un logement esclave 28 (pair) et un logement de blocage 30.The inner surface 18 of the base body 16 has a slave housing 28 (even) and a locking housing 30.

Chaque tampon 6, 8 est muni en outre d'au moins un organe de blocage 32.Each buffer 6, 8 is further provided with at least one locking member 32.

Le type de tampon esclave 6 ou maître 8 est défini par la présence ou l'absence de l'organe de blocage 32 dans le logement esclave 28. Lorsque l'organe de blocage 32 est présent dans le logement esclave 28, le tampon constitue un tampon esclave 6, et lorsqu'aucun organe de blocage 32 n'est présent dans le logement esclave 28, le tampon est un tampon maître 8. Le tampon maître 8 comporte par ailleurs un verrou (non représenté) adapté pour verrouiller le tampon maître 8 par rapport au cadre 4.The type of slave buffer 6 or master 8 is defined by the presence or absence of the locking member 32 in the slave housing 28. When the locking member 32 is present in the slave housing 28, the buffer constitutes a slave buffer 6, and when no blocking member 32 is present in the slave housing 28, the buffer is a master buffer 8. The master buffer 8 further comprises a latch (not shown) adapted to lock the master buffer 8 relative to the frame 4.

Sur la Figure 10 est représenté en coupe transversale parallèlement à l'axe X-X le regard 2 au niveau du logement esclave 28 du tampon esclave 6.On the Figure 10 is shown in cross section parallel to the axis XX the view 2 at the slave housing 28 of the slave buffer 6.

Le logement esclave 28 comporte une paroi de fond 34 et deux ouvertures de logement 36, 38 ménagées dans des parois latérales de l'évidement de manoeuvre 26.The slave housing 28 has a bottom wall 34 and two housing openings 36, 38 formed in side walls of the operating recess 26.

La paroi de fond 34 s'étend parallèlement au plan de tampon T-T. Les ouvertures de logement 36,38 s'étendent sensiblement perpendiculairement au plan de tampon T-T.The bottom wall 34 extends parallel to the T-T buffer plane. The housing openings 36, 38 extend substantially perpendicular to the T-T buffer plane.

Le logement esclave 28 définit un sens SI d'introduction de l'organe de blocage 32 dans ce logement 28 qui est sensiblement parallèle au plan de tampon T-T.The slave housing 28 defines a direction SI of insertion of the locking member 32 into the housing 28 which is substantially parallel to the T-T buffer plane.

L'organe de blocage 32 est en l'occurrence un crampon ayant une âme 40 et deux ailes 42, 44, le crampon ayant une forme sensiblement de « U ». L'organe de blocage 32 comporte un ergot de blocage 46, et en l'occurrence deux ergots de blocage 46. L'ergot de blocage 46 est destiné à entrer en contact avec le tampon voisin, en l'occurrence avec le tampon maître 8, afin d'empêcher le soulèvement du tampon esclave 6 lorsque le tampon maître 8 se trouve dans le cadre 4. Chaque ergot de blocage 46 fait saillie de l'âme 40 du crampon du côté opposé des ailes 42, 44.The locking member 32 is in this case a crampon having a core 40 and two wings 42, 44, the crampon having a substantially "U" shape. The locking member 32 comprises a locking pin 46, and in this case two locking lugs 46. The locking lug 46 is intended to come into contact with the neighboring buffer, in this case with the master buffer 8 , in order to prevent lifting of the slave pad 6 when the master pad 8 is in the frame 4. Each locking pin 46 protrudes from the core 40 of the crampon on the opposite side of the wings 42, 44.

A l'état monté, l'une 42 des ailes se trouve dans le logement esclave 28, tandis que l'autre aile 44 s'étend en dehors du logement esclave 28, de l'autre côté de la paroi de fond 34.In the mounted state, one 42 of the wings is in the slave housing 28, while the other wing 44 extends outside the slave housing 28, on the other side of the bottom wall 34.

De manière avantageuse, l'organe de blocage 32 est symétrique par rapport à un axe de symétrie Z-Z. Ainsi, l'organe de blocage 32 peut être inséré dans le logement 28 dans la position indiquée sur la Figure 10 ou dans une position tournée de 180° autour de l'axe de symétrie Z-Z, ce qui facilite la manipulation et le montage. Dans ce dernier cas, c'est l'aile 44 qui se trouve dans le logement esclave 28 et l'aile 42 se trouve en dehors de ce logement 28, de l'autre côté de la paroi de fond 34.Advantageously, the locking member 32 is symmetrical about an axis of symmetry ZZ. Thus, the locking member 32 can be inserted into the housing 28 in the position indicated on the Figure 10 or in a position rotated 180 ° around the axis of symmetry ZZ, which facilitates handling and assembly. In the latter case, it is the wing 44 which is in the slave housing 28 and the wing 42 is outside this housing 28, on the other side of the bottom wall 34.

Le logement esclave 28 est adapté pour maintenir l'organe de blocage 32 par rapport au corps de base 16 d'une manière autonome dans un sens S s'étendant perpendiculairement au plan de tampon T-T et dirigé à l'écart de la surface extérieure 20. En d'autres termes, le logement esclave 28 est adapté pour s'opposer à un déplacement de l'organe de blocage 32 vers le côté intérieur l par rapport au corps de base 16 et ceci en l'absence de tout autre moyen de maintien. Grâce au fait que le logement esclave 28 est formé par l'évidement de manoeuvre 26, le corps de base 16 ne nécessite que peu de matière, et en tout état de cause, il n'y a pas de matière superflue en cas de non utilisation du logement esclave 28.The slave housing 28 is adapted to hold the locking member 32 with respect to the base body 16 in an autonomous manner in a direction S extending perpendicularly to the buffer plane TT and directed away from the outer surface 20 In other words, the slave housing 28 is adapted to oppose a displacement of the locking member 32 towards the inner side 1 with respect to the base body 16 and this in the absence of any other means of maintenance. Due to the fact that the slave housing 28 is formed by the operating recess 26, the basic body 16 requires little material, and in any case, there is no superfluous material in case of no use of slave housing 28.

Lors de la fabrication du corps de base 16, les ouvertures de logement 36, 38 ne sont pas nécessairement créées. Lorsque ces ouvertures 36, 38 ne sont pas ménagées dans le tampon lors de sa fabrication, chaque emplacement des ouvertures de logement 36, 38 est entièrement recouvert d'une paroi d'obturation 50 ayant une épaisseur e sensiblement inférieure à une épaisseur de paroi EP des parois latérales de l'évidement de manoeuvre 26 du corps de base 16. De préférence, l'épaisseur e est comprise entre 0,1 mm et 1 mm. Ces parois d'obturation 50 forment une barrière d'étanchéité de l'évidement de manoeuvre 26 par rapport au côté intérieur l du regard d'accès 2. Ainsi, lorsque l'organe de blocage 32 n'est pas mis en place dans le logement esclave 28, étant donné que le corps de base 16 est utilisé pour un tampon maître 8, des eaux pluviales ou détritus divers ne peuvent pas pénétrer par l'évidement de manoeuvre 26 dans l'intérieur du regard 2.In the manufacture of the base body 16, the housing openings 36, 38 are not necessarily created. When these openings 36, 38 are not provided in the buffer during its manufacture, each location of the housing openings 36, 38 is completely covered by a closure wall 50 having a thickness e substantially less than an EP wall thickness. side walls of the operating recess 26 of the base body 16. Preferably, the thickness e is between 0.1 mm and 1 mm. These closing walls 50 form a sealing barrier for the operating recess 26 with respect to the inner side 1 of the access door 2. Thus, when the locking member 32 is not put in place in the slave housing 28, since the base body 16 is used for a master buffer 8, rainwater or various detritus can not penetrate through the operating recess 26 in the interior of the eye 2.

La paroi 50 est frangible et doit être rompue afin de mettre l'organe de blocage 32 en place dans le logement esclave 28 pour la première fois.The wall 50 is frangible and must be broken in order to put the locking member 32 in place in the slave housing 28 for the first time.

Le tampon esclave 6 comporte en outre des moyens d'assujettissement 60 de l'organe de blocage 32 sur le corps de base 16. Ces moyens d'assujettissement 60 sont adaptés pour s'opposer à un retrait de l'organe de blocage 32 du logement esclave 28. Les moyens d'assujettissement 60 coopèrent par complémentarité de formes d'une part avec l'organe de blocage 32 et d'autre part avec le corps de base 16. A cet effet, l'organe de blocage 32 comporte une surface d'assujettissement 62, en l'occurrence délimitée par un évidement, tandis qu'une autre surface d'assujettissement 64 est délimitée par le corps de base 16. Les moyens d'assujettissement 60 comprennent par ailleurs un organe d'assujettissement, notamment une goupille 66, inséré entre les surfaces d'assujettissement 62 et 64.The slave buffer 6 further comprises securing means 60 of the locking member 32 on the base body 16. These securing means 60 are adapted to oppose a withdrawal of the locking member 32 of the Slave housing 28. The securing means 60 cooperate by complementary forms on the one hand with the locking member 32 and on the other hand with the base body 16. For this purpose, the locking member 32 comprises a securing surface 62, in this case delimited by a recess, while another securing surface 64 is delimited by the base body 16. The securing means 60 furthermore comprise an element for securing, in particular a pin 66, inserted between the securing surfaces 62 and 64.

Le tampon esclave 6 comporte également des moyens de guidage 70 adaptés pour guider l'organe de blocage 32 par rapport au corps de base 16 lors de l'insertion de cet organe de blocage dans le logement esclave 28. Comme ceci ressort particulièrement de la Figure 9, les moyens de guidage 70 comprennent une rainure de guidage 72 dans laquelle glisse l'aile 44 de l'organe de blocage 32 lors de l'insertion de l'aile 42 dans le logement esclave 28.The slave buffer 6 also comprises guide means 70 adapted to guide the locking member 32 relative to the base body 16 during the insertion of this locking member in the slave housing 28. As is particularly apparent from the Figure 9 , the guide means 70 comprise a guide groove 72 in which the flange 44 of the locking member 32 slides during the insertion of the flange 42 into the slave housing 28.

De préférence, l'organe de blocage 32 est fabriqué en métal et plus particulièrement en fonte. De préférence, la matière du corps de base 16 et de l'organe de blocage 32 sont identiques afin d'éviter la corrosion de l'un ou de l'autre de ces éléments.Preferably, the locking member 32 is made of metal and more particularly cast iron. Preferably, the material of the base body 16 and the locking member 32 are identical in order to avoid corrosion of one or the other of these elements.

Sur les Figures 4 à 7 est montrée la partie du regard 2 au niveau du logement de blocage 30. Le logement de blocage 30 est adapté pour recevoir un organe de blocage 32 afin de bloquer un côté du tampon 6 ou 8 par rapport à un côté du cadre 4. La configuration et le fonctionnement du logement de blocage 30 et de l'organe de blocage 32 sont analogues au fonctionnement du logement esclave 28 et de l'organe de blocage 32 précédemment décrit, et ne diffèrent de ceux-ci que par ce qui suit.On the Figures 4 to 7 is shown the portion of the view 2 at the locking housing 30. The locking housing 30 is adapted to receive a locking member 32 to block one side of the pad 6 or 8 with respect to a side of the frame 4. The configuration and the operation of the locking housing 30 and the locking member 32 are analogous to the operation of the slave housing 28 and the locking member 32 described above, and differ from them only in the following.

L'organe de blocage 32 ne coopère pas avec un tampon voisin, mais coopère avec la base 14 du cadre 4. Plus précisément, un ergot de blocage 46 de l'organe de blocage 32 est adapté pour s'engager sous une surface de butée 74 du cadre formant gâche pour l'organe de blocage 32. Cette surface de butée 74 s'étend parallèlement au plan de regard P-P, est située du côté intérieur de la base 14 et est délimitée par une paroi d'entourage 76. La paroi d'entourage 76 est en saillie vers l'intérieur, parallèlement à l'axe X-X, empêchant ainsi la pénétration de matériau de scellement du cadre à l'emplacement de la surface de butée 74.The locking member 32 does not cooperate with a neighboring buffer, but cooperates with the base 14 of the frame 4. More specifically, a locking pin 46 of the locking member 32 is adapted to engage under a stop surface 74 of the striker frame for the locking member 32. This abutment surface 74 extends parallel to the viewing plane PP, is located on the inner side of the base 14 and is delimited by a surrounding wall 76. The wall surround 76 extends inwardly in parallel with the axis XX, thereby preventing the penetration of frame sealing material at the location of the abutment surface 74.

Comme ceci ressort de la Figure 3, l'élément de blocage 32 est inséré dans le logement 30, aussi bien sur le tampon esclave 6 que sur le tampon maître 8, et sert à empêcher le soulèvement du tampon esclave 6 et du tampon maître 8 par rapport au cadre 4.As is apparent from the Figure 3 , the blocking element 32 is inserted in the housing 30, both on the slave buffer 6 and on the master buffer 8, and serves to prevent the lifting of the slave buffer 6 and the master buffer 8 with respect to the frame 4.

De plus, la paroi de fond 34 a une surface intérieure étagée qui conduit à une faible consommation de matière et permet de bloquer la goupille 66.In addition, the bottom wall 34 has a stepped interior surface which leads to a low consumption of material and makes it possible to lock the pin 66.

Sur la Figure 11 est représenté un regard d'accès 2 selon une variante de l'invention. Ce regard d'accès 2 diffère du regard d'accès 2 précédemment décrit uniquement par ce qui suit.On the Figure 11 is shown an access view 2 according to a variant of the invention. This access port 2 differs from the access port 2 previously described only by the following.

Le cadre 4 a une forme sensiblement rectangulaire. Le regard d'accès 2 comporte un tampon maître 8 et trois tampons esclaves. Ces trois tampons esclaves comprennent deux tampons esclaves pairs 6P et un tampon esclave impair 6I. Les deux tampons esclaves pairs 6P sont identiques au tampon esclave 6 précédemment décrit.The frame 4 has a substantially rectangular shape. The access window 2 comprises a master buffer 8 and three slave buffers. These three slave buffers comprise two even slave buffers 6P and an odd slave buffer 6I. The two even slave buffers 6P are identical to the slave buffer 6 previously described.

Les tampons esclaves pairs 6P comprennent chacun un corps de base 16 ayant un logement esclave pair 28P identique au logement esclave 28 précité.The even slave buffers 6P each comprise a base body 16 having an even slave slot 28P identical to the slave slot 28 mentioned above.

Dans le cas des tampons esclaves pairs 6P, l'organe de blocage 32 est inséré selon un premier sens d'introduction SI1 dans le logement esclave pair 28P, ce sens d'introduction SI1 étant considéré par rapport à ce logement 28P. Lorsque l'organe de blocage 32 est reçu dans le logement esclave pair 28P selon ce premier sens, le tampon 6 constitue un tampon esclave pair 6P.In the case of even slave buffers 6P, the locking member 32 is inserted in a first insertion direction SI1 in the even slave housing 28P, this insertion direction SI1 being considered with respect to this housing 28P. When the locking member 32 is received in the even slave slot 28P in this first direction, the buffer 6 constitutes an even slave buffer 6P.

Le tampon esclave impair 6I est disposé entre les deux tampons esclaves pairs 6P.The odd slave buffer 6I is disposed between the two even 6P slave buffers.

Ce tampon esclave impair 6I comporte un corps de base 16 ayant un logement esclave impair 28I identique au logement esclave 28 précité et dans lequel s'étend un organe de blocage 32. L'organe de blocage 32 est inséré selon un deuxième sens d'introduction SI2 dans le logement esclave impair 28I, ce sens d'introduction étant considéré par rapport à ce logement 28I. Lorsque l'organe de blocage 32 est reçu selon ce deuxième sens SI2 dans le logement 28I, le tampon constitue un tampon esclave impair 61. Il est à noter que le deuxième sens d'introduction I2 est différent du premier sens d'introduction SI1, et est dans le cas présent un sens opposé au premier sens d'introduction SI1. Aussi, sur la Figure 11, les deux sens SI1 et SI2 sont dirigés dans le même sens, étant donné que le tampon esclave impair 6I est tourné de 180° par rapport aux tampons esclaves pairs 6P.This odd slave buffer 6I comprises a base body 16 having an odd slave housing 28I identical to the aforementioned slave housing 28 and in which a locking member 32 extends. The locking member 32 is inserted in a second direction of insertion. SI2 in the odd slave housing 28I, this direction of introduction being considered with respect to this housing 28I. When the locking member 32 is received in this second sense SI2 in the housing 28I, the buffer constitutes an odd slave buffer 61. It should be noted that the second insertion direction I2 is different from the first insertion direction SI1, and is in this case a direction opposite to the first insertion direction SI1. Also, on the Figure 11 the two directions SI1 and SI2 are directed in the same direction, since the odd slave buffer 6I is rotated 180 ° with respect to the even slave buffers 6P.

Les logements esclaves pairs 28P et impair 28I sont identiques, leur fonction est uniquement définie par le sens d'introduction de l'organe de blocage.The even slave 28P and odd 28I slots are identical, their function is defined solely by the direction of insertion of the locking member.

En d'autres termes, le type de tampon, à savoir tampon esclave pair 6P ou tampon esclave impair 6I est défini par le sens d'introduction de l'organe de blocage 32 dans le logement esclave.In other words, the type of buffer, namely an even slave buffer 6P or an odd slave buffer 6I, is defined by the direction of insertion of the locking member 32 into the slave housing.

Lorsque l'organe de blocage 32 est disposé dans le logement esclave selon le deuxième sens d'introduction SI2, le tampon esclave impair 6I ne peut pas être disposé sur le cadre 4 ou retiré du cadre 4 tant que le tampon esclave pair 6P adjacent à cet organe de blocage 32 est en place.When the locking member 32 is disposed in the slave housing according to the second insertion direction SI2, the odd slave buffer 6I can not be placed on the frame 4 or removed from the frame 4 as long as the even slave buffer 6P adjacent to this locking member 32 is in place.

Ainsi, afin d'ouvrir le regard 2, il est nécessaire de retirer tout d'abord le tampon maître 8, ensuite le tampon pair 6P disposé entre le tampon maître 8 et le tampon impair 61, ensuite le tampon impair 61 et finalement l'autre tampon pair 6P disposé à l'opposé du tampon maître 8.Thus, in order to open the window 2, it is necessary to first remove the master buffer 8, then the even buffer 6P disposed between the master buffer 8 and the odd buffer 61, then the odd buffer 61 and finally the another even buffer 6P arranged opposite the master buffer 8.

Il est à noter que le corps de base 16 du tampon esclave impair 6I est identique aux corps de base 16 du tampon maître 8 et des tampons esclaves pairs 6P.It should be noted that the base body 16 of the odd slave buffer 6I is identical to the basic bodies 16 of the master buffer 8 and the even 6P slave buffers.

Par ailleurs, le tampon maître 8 peut comporter un verrou 80 adapté pour verrouiller le tampon maître 8 par rapport au cadre.Furthermore, the master buffer 8 may include a latch 80 adapted to lock the master pad 8 relative to the frame.

Cette variante a un coût de production particulièrement faible, étant donné qu'un seul logement 28 est nécessaire pour définir deux types de tampon.This variant has a particularly low production cost, since only one housing 28 is necessary to define two types of buffer.

Une variante non représentée d'un regard d'accès 2 de la Figure 11 comporte les caractéristiques suivantes. Ce regard d'accès 2 diffère du regard d'accès 2 de la Figure 11 uniquement par ce qui suit.An unrepresented variant of an access window 2 of the Figure 11 has the following characteristics. This access point 2 differs from the access point 2 of the Figure 11 only by the following.

Les tampons esclaves comprennent chacun un corps de base 16 ayant un premier logement esclave, identique au logement esclave 28 précité, ainsi qu'un second logement esclave qui est distinct du premier logement esclave. Ce second logement esclave est par exemple disposé au milieu d'un côté du tampon esclave. Lorsque l'organe de blocage 32 est reçu dans le premier logement esclave, le tampon 6 constitue un tampon esclave pair. Lorsque l'organe de blocage est disposé dans le second logement esclave, le tampon 6 constitue un tampon esclave impair.The slave buffers each comprise a base body 16 having a first slave slot, identical to the slave slot 28 above, and a second slave slot which is distinct from the first slave slot. This second slave housing is for example disposed in the middle of one side of the slave buffer. When the locking member 32 is received in the first slave housing, the buffer 6 constitutes an even slave buffer. When the locking member is disposed in the second slave housing, the buffer 6 constitutes an odd slave buffer.

Lorsque l'organe de blocage 32 est disposé dans ce second logement esclave, le tampon esclave impair ne peut pas être disposé sur le cadre 4 ou retiré du cadre 4 tant que le tampon esclave pair adjacent à ce logement esclave est en place.When the locking member 32 is disposed in this second slave housing, the odd slave buffer can not be placed on the frame 4 or removed from the frame 4 as long as the even slave buffer adjacent to this slave housing is in place.

Il est à noter que le corps de base du tampon esclave impair est de préférence identique aux corps de base du tampon maître et des tampons esclaves pairs.It should be noted that the base body of the odd slave buffer is preferably identical to the master bodies of the master buffer and even slave buffers.

A cet effet, chacun des corps de base des tampons comporte un logement esclave pair, un logement esclave impair ainsi qu'un logement de blocage. Lorsque l'organe de blocage est inséré dans le logement esclave pair, le tampon constitue un tampon esclave pair. Lorsque l'organe de blocage est inséré dans le logement esclave impair, le tampon constitue un tampon esclave impair. Lorsque ni dans le logement esclave pair ni dans le logement esclave impair n'est inséré un organe de blocage, le tampon constitue un tampon maître.For this purpose, each of the basic bodies of the buffers comprises an even slave housing, an odd slave housing and a locking housing. When the locking member is inserted into the even slave slot, the buffer constitutes an even slave buffer. When the locking member is inserted into the odd slave housing, the buffer constitutes an odd slave buffer. When neither the even slave slot nor the odd slave slot has a locking member inserted, the buffer constitutes a master buffer.

Ainsi, un seul corps de base 16 est utilisable pour constituer un tampon maître, un tampon esclave pair ou un tampon esclave impair. De plus, un même organe de blocage 32 est utilisable pour créer le type de tampon souhaité. Le regard d'accès 2 a donc un coût de production faible.Thus, a single base body 16 can be used to constitute a master buffer, an even slave buffer or an odd slave buffer. In addition, the same blocking member 32 can be used to create the desired type of buffer. The access window 2 therefore has a low production cost.

En variante non représentée, l'organe de blocage 32 est muni de moyens anti-fermeture adaptés pour s'opposer à la fermeture du tampon lorsque celui-ci est en position ouverte.In variant not shown, the locking member 32 is provided with anti-closure means adapted to oppose the closure of the buffer when it is in the open position.

Ces moyens anti-fermeture sont par exemple réalisés sous la forme d'une tige fixée à l'âme 40 uniquement lorsque le tampon est en position ouverte. Cette tige s'étend entre les deux ergots 46 et son extrémité libre vient en appui contre la paroi de la chambre souterraine, s'opposant ainsi à la fermeture intempestive du tampon.These anti-closure means are for example made in the form of a rod attached to the core 40 only when the buffer is in the open position. This rod extends between the two lugs 46 and its free end abuts against the wall of the underground chamber, thus opposing the inadvertent closure of the buffer.

Enfin, le fait que l'organe de blocage soit monté parallèlement au plan de tampon dans le logement associé facilite la tenue de cet organe dans le logement.Finally, the fact that the locking member is mounted parallel to the buffer plane in the associated housing facilitates the holding of this member in the housing.
