En se reportant aux figures, la référence 1 désigne un dispositif de voirie formant regard de chaussée réalisé de préférence en fonte et comprenant un cadre de support 2 et au moins un élément de couronnement ou de fermeture 3, tel qu'un tampon ou couvercle, d'obturation de l'ouverture délimitée par le cadre de support 2.Referring to the figures, the reference numeral 1 designates a roadway device forming a manhole made preferably of cast iron and comprising a support frame 2 and at least one crown or closure element 3, such as a buffer or cover, closing the opening delimited by the support frame 2.

Un tel regard peut être disposé sur la voie publique pour accéder notamment à une cheminée de visite de galerie souterraine.Such a look can be arranged on the public road to access including a tunnel underground tunnel.

Les figures montrent que le dispositif de voirie comprend un seul élément de couronnement 3 constitué par un tampon de forme générale rectangulaire et apte à s'inscrire en épaisseur par ses quatre parois périphériques 4 faisant saillie en dessous du voile plan supérieur 3a du tampon 3 dans les quatre parois périphériques 5 du cadre 2 pour obturer l'ouverture de ce cadre délimitée par les quatre parois 5.The figures show that the road device comprises a single crown element 3 consisting of a generally rectangular shaped buffer and able to register in thickness by its four peripheral walls 4 projecting below the upper plane web 3a of the buffer 3 in the four peripheral walls 5 of the frame 2 to close the opening of this frame delimited by the four walls 5.

Le tampon 3 peut être désengagé du cadre 2 par soulèvement comme on le verra ultérieurement.The buffer 3 can be disengaged from the frame 2 by lifting as will be seen later.

Les parois 4 du tampon 3 ont leurs faces externes inclinées de manière à s'engager jointivement respectivement avec les faces internes inclinées correspondantes des parois 5 du cadre 2 lorsque le tampon 3 occupe sa position de fermeture de ce cadre. Pour désengager le tampon 3 du cadre 2, il suffit d'exercer sur le tampon 3 un effort de traction le soulevant et provoquant le glissement des faces externes des parois 4 du tampon 3 relativement aux faces internes correspondantes des parois 5 du cadre 2.The walls 4 of the buffer 3 have their external faces inclined so as to engage respectively with the respective inclined inner faces of the walls 5 of the frame 2 when the buffer 3 occupies its closed position of this frame. To disengage the buffer 3 from the frame 2, it suffices to exert on the pad 3 a traction force lifting it and causing the sliding of the outer faces of the walls 4 of the pad 3 relative to the corresponding inner faces of the walls 5 of the frame 2.

Les quatre parois latérales 5 du cadre 2 sont assemblées les unes aux autres par un ensemble de brides 6 et de boulons de fixation B pour constituer ce cadre. Cependant, les quatre parois latérales 5 du cadre 2 peuvent être réalisées en une seule pièce en fonderie.The four side walls 5 of the frame 2 are assembled to each other by a set of flanges 6 and fixing bolts B to form this frame. However, the four side walls 5 of the frame 2 can be made in one piece in the foundry.

Le tampon 3 est équipé d'un dispositif permettant de verrouiller le tampon 3 dans le cadre de support 2 à sa position de fermeture de ce dernier.The buffer 3 is equipped with a device for locking the buffer 3 in the support frame 2 at its closed position of the latter.

Ce dispositif de verrouillage comprend un pêne 7 monté mobile à coulissement guidé sous le tampon 3 et pouvant coopérer avec une gâche 8 du cadre 2 pour verrouiller le tampon 3 dans ce cadre.This locking device comprises a bolt 7 mounted movably sliding guided under the buffer 3 and can cooperate with a keeper 8 of the frame 2 to lock the buffer 3 in this frame.

La gâche 8 peut être constituée par un évidement formé dans l'une des parois 5 du cadre 2 de manière à recevoir l'extrémité libre du pêne de verrouillage 7.The striker 8 may consist of a recess formed in one of the walls 5 of the frame 2 so as to receive the free end of the locking bolt 7.

Comme représenté notamment en figure 2, le pêne 7 est monté mobile suivant une direction perpendiculaire à l'une des parois longitudinales 4 du tampon 3 de façon que son extrémité libre puisse s'engager dans la gâche 8 réalisée dans la paroi longitudinale en vis-à-vis 5 du cadre 2. Cependant, le pêne 7 peut être monté mobile suivant une direction perpendiculaire à l'autre paroi longitudinale 4 du tampon 3 ou à l'une ou l'autre des parois transversales 4 de ce tampon de manière que l'extrémité libre du pêne 7 puisse s'engager dans une gâche 8 formée dans l'autre paroi longitudinale 5 du cadre 2 ou l'une ou l'autre des deux parois transversales 5 de ce cadre.As shown in particular in figure 2 , the bolt 7 is movably mounted in a direction perpendicular to one of the longitudinal walls 4 of the buffer 3 so that its free end can engage in the keeper 8 made in the longitudinal wall facing the frame 5 2. However, the bolt 7 may be mounted to move in a direction perpendicular to the other longitudinal wall 4 of the buffer 3 or to one or the other of the transverse walls 4 of this buffer so that the free end of the bolt 7 can engage in a keeper 8 formed in the other longitudinal wall 5 of the frame 2 or one or the other of the two transverse walls 5 of this frame.

Le voile plan 3a du tampon 3 comporte une ouverture débouchante 10 traversant l'épaisseur de ce voile et permettant à la clef 9 d'accéder au pêne de verrouillage 7.The plane web 3a of the buffer 3 has a through opening 10 passing through the thickness of this web and allowing the key 9 to access the locking bolt 7.

Selon l'invention, l'ouverture 10 du tampon 3 est conformée pour permettre à la clef 9 d'actionner le pêne 7 par pivotement d'elle-même dans un plan perpendiculaire au plan du voile 3a du tampon 3.According to the invention, the opening 10 of the buffer 3 is shaped to allow the key 9 to actuate the bolt 7 by pivoting itself in a plane perpendicular to the plane of the web 3a of the buffer 3.

La clef d'actionnement 9 comprend une tige cylindrique de relativement grande longueur 11 pourvue à l'une de ses extrémités d'une poignée de manoeuvre 12 constituée par une barre s'étendant perpendiculairement à la tige 11.The operating key 9 comprises a cylindrical rod of relatively large length 11 provided at one of its ends with an operating handle 12 constituted by a bar extending perpendicularly to the rod 11.

La clef d'actionnement 9 comprend en outre au voisinage de l'extrémité libre 13 de la tige 11 opposée à la poignée de manoeuvre 12 un barreau 14 solidaire perpendiculairement de la tige 11 de part et d'autre de celle-ci, lequel barreau 14 est situé dans le même plan que celui contenant la poignée de manoeuvre 12.The actuating key 9 further comprises, in the vicinity of the free end 13 of the rod 11 opposite to the operating handle 12, a bar 14 integral perpendicularly with the rod 11 on either side thereof, which bar 14 is located in the same plane as that containing the operating handle 12.

La clef d'actionnement 9 comprend également des moyens permettant de bloquer celle-ci à une position sensiblement perpendiculaire au voile plan 3a du tampon 3 une fois le pêne 7 occupant sa position totalement déverrouillée.The actuating key 9 also comprises means for blocking the latter at a position substantially perpendicular to the plane web 3a of the buffer 3 once the bolt 7 occupies its fully unlocked position.

Ces moyens de blocage comprennent un fourreau 15 monté coulissant à faible jeu le long de la tige 11 de la clef 9 et une clavette 16 solidaire du fourreau 15 le long d'une partie de ce dernier en faisant saillie au-delà du bord inférieur du fourreau 15 situé du côté du barreau 14. Ainsi, la clavette 16 s'étend parallèlement à la tige 11 de la clef d'actionnement 9. Le fourreau 15 est pourvu d'une poignée de manoeuvre 17 solidaire de ce fourreau et constituée par une barre s'étendant perpendiculairement du fourreau d'un côté de celui-ci. La poignée 17 permet de déplacer manuellement le fourreau 15 et la clavette 16 le long de la tige 11 à la position de blocage de la clef d'actionnement 9 comme on le verra ultérieurement.These locking means comprise a sleeve 15 slidably mounted with a small clearance along the shaft 11 of the key 9 and a key 16 integral with the sleeve 15 along a portion of the latter projecting beyond the lower edge of the sheath 15 located on the side of the bar 14. Thus, the key 16 extends parallel to the rod 11 of the actuating key 9. The sleeve 15 is provided with an operating handle 17 secured to this sheath and constituted by a bar extending perpendicularly from the sheath to one side thereof. The handle 17 makes it possible to manually move the sheath 15 and the key 16 along the rod 11 to the locking position of the operating key 9 as will be seen later.

Le pêne de verrouillage 7 comprend une tige cylindrique 18 traversant à coulissement guidé un perçage 19 réalisé au travers d'une paroi ou nervure de renforcement 20 solidaire du voile plan 3a du tampon 3 en dessous de celui-ci suivant une direction perpendiculaire à ce voile.The locking bolt 7 comprises a cylindrical rod 18 traversing with sliding guided a bore 19 made through a wall or reinforcing rib 20 secured to the plane web 3a of the pad 3 below it in a direction perpendicular to this veil .

Le pêne 7 comprend en outre, solidaire de la tige 18 et en prolongement de celle-ci, une partie sensiblement en forme de parallépipède rectangle plat 21 dont l'extrémité libre biseautée peut s'engager dans l'évidement formant gâche 8 de la paroi correspondante 5 du cadre 2, évidement présentant alors la forme d'une fenêtre rectangulaire.The bolt 7 further comprises, integral with the rod 18 and in extension thereof, a substantially rectangular parallelepiped shaped portion 21 whose free beveled end can engage in the recess forming latch 8 of the wall corresponding 5 of the frame 2, recess then having the shape of a rectangular window.

Le pêne 7 est rappelé à sa position de verrouillage dans la gâche 8 par un ressort hélicoïdal de compression 22 monté précontraint entre la partie plate 21 du pêne 7 et la face plane correspondante de la nervure de renforcement 20 en étant disposé coaxialement autour de la tige 18 du pêne 7. La partie plate 21 du pêne 7 présente une largeur supérieure au diamètre de la tige 18 pour définir un épaulement sur lequel est en appui une spire extrême du ressort 22.The bolt 7 is returned to its locking position in the striker 8 by a helical compression spring 22 mounted prestressed between the flat portion 21 of the bolt 7 and the corresponding flat face of the reinforcing rib 20 being disposed coaxially around the rod. 18 of the bolt 7. The flat portion 21 of the bolt 7 has a width greater than the diameter of the rod 18 to define a shoulder on which is supported an extreme turn of the spring 22.

Le pêne 7 est retenu axialement sous le tampon 3 pour empêcher le pêne 7 de s'échapper de ce tampon une fois ce dernier désengagé du cadre 2 par un anneau extérieur 23 monté coaxialement sur la partie d'extrémité libre de la tige 18 faisant saillie de la nervure de renforcement 20 à l'opposé du ressort 22 et qui est bloqué en translation par une goupille 24. De la sorte, lorsque le tampon 3 est totalement désengagé du cadre de support 2 et en l'absence de la clef 9 une fois retirée du tampon, la force exercée par le ressort 22 sur la partie plate 21 du pêne 7 amène en butée l'anneau 23 sur la face plane correspondante de la nervure de renforcement 20 opposée à celle sur laquelle est en appui la spire extrême correspondante du ressort 22.The bolt 7 is retained axially under the buffer 3 to prevent the bolt 7 from escaping from this buffer once the latter disengaged from the frame 2 by an outer ring 23 mounted coaxially on the free end portion of the rod 18 protruding reinforcement rib 20 opposite the spring 22 and which is locked in translation by a pin 24. In this way, when the pad 3 is completely disengaged from the support frame 2 and in the absence of the key 9 a once removed from the buffer, the force exerted by the spring 22 on the flat portion 21 of the bolt 7 abuts the ring 23 on the corresponding flat face of the reinforcing rib 20 opposite to that on which the corresponding extreme turn is supported. of the spring 22.

La partie plate 21 du pêne 7 traverse une ouverture rectangulaire 4a de la paroi latérale correspondante 4 du tampon 3 de manière à assurer également le guidage en translation du pêne 7 sous le tampon 3.The flat portion 21 of the bolt 7 passes through a rectangular opening 4a of the corresponding lateral wall 4 of the buffer 3 so as to also ensure the translational guidance of the bolt 7 under the buffer 3.

La partie plate 21 du pêne 7 comporte un orifice traversant 25 constitué d'un perçage central 26 et de deux chanfreins circulaires ou tronconiques 27 situés de part et d'autre du perçage central 26. L'orifice 25 est destiné à recevoir l'extrémité libre 13 de la tige 11 de la clef d'actionnement 9 lorsque cette dernière est introduite au travers de l'ouverture 10 du tampon 3.The flat portion 21 of the bolt 7 comprises a through hole 25 consisting of a central bore 26 and two circular or frustoconical bevels 27 located on either side of the central bore 26. The orifice 25 is intended to receive the end free 13 of the rod 11 of the operating key 9 when the latter is introduced through the opening 10 of the buffer 3.

L'ouverture 10 du tampon 3 est en outre conformée pour guider le passage de la clef d'actionnement 9 au travers du tampon 3 et l'introduction de l'extrémité libre 13 de cette clef dans l'orifice 25 du pêne 7 avant d'actionner ce dernier par pivotement de la clef 9 dans l'ouverture 10.The opening 10 of the buffer 3 is further shaped to guide the passage of the actuating key 9 through the buffer 3 and the introduction of the free end 13 of this key into the hole 25 of the bolt 7 before actuate the latter by pivoting the key 9 in the opening 10.

De préférence, l'ouverture 10 du tampon 3 présente une forme générale rectangulaire vue de dessus du tampon 3 et dont les deux bords supérieurs longitudinaux situés au niveau de la face supérieure du voile plan 3a du tampon 3 s'étendent parallèlement au plan de la nervure de renforcement 20 ou à la paroi 4 du tampon 3 traversée par le pêne 7.Preferably, the opening 10 of the buffer 3 has a generally rectangular shape seen from above the buffer 3 and whose two longitudinal upper edges located at the upper face of the plane web 3a of the buffer 3 extend parallel to the plane of the reinforcing rib 20 or the wall 4 of the buffer 3 through which the bolt 7 passes.

L'ouverture 10 comporte deux rampes parallèles 28 partant respectivement des deux bords supérieurs de cette ouverture au travers de l'épaisseur du voile plan 3a du tampon 3 en débouchant sous celui-ci au dessus du pêne 7. Les deux rampes 28 assurent le guidage du barreau transversal 14 et de l'introduction de l'extrémité libre 13 de la clef d'actionnement 9 dans l'orifice 25 du pêne 7 lorsque la clef 9 est introduite au travers de l'ouverture 10 du tampon 3 occupant sa position d'obturation du cadre 2. L'épaisseur du barreau 14 est légèrement inférieure à la distance séparant les deux rampes 28 et la longueur de ce barreau est légèrement inférieure à la longueur de ces rampes.The opening 10 comprises two parallel ramps 28 respectively starting from the two upper edges of this opening through the thickness of the plane web 3a of the buffer 3 opening under it above the bolt 7. The two ramps 28 provide guidance 14 of the transverse bar 14 and the introduction of the free end 13 of the actuating key 9 in the hole 25 of the bolt 7 when the key 9 is introduced through the opening 10 of the buffer 3 occupying its position d 2. The thickness of the bar 14 is slightly less than the distance separating the two ramps 28 and the length of this bar is slightly less than the length of these ramps.

De préférence, l'angle d'inclinaison α de chaque rampe 28 est sensiblement égal à l'angle d'inclinaison β des chanfreins 27 de l'orifice 25 du pêne 7. Par exemple, les angles d'inclinaison α et β peuvent être d'environ 50°.Preferably, the angle of inclination α of each ramp 28 is substantially equal to the angle of inclination β of the chamfers 27 of the orifice 25 of the bolt 7. For example, the angles of inclination α and β may be about 50 °.

L'ouverture 10 du tampon 3 comporte en outre une lumière ou rainure 29 débouchant dans l'épaisseur du voile plan 3a du tampon 3, perpendiculaire aux rampes 28 et s'étendant à partir du côté supérieur longitudinal de l'une de ces rampes. Plus précisément, la lumière 29 s'étend à partir de la rampe 28 de l'ouverture 10 située la plus proche de la paroi latérale 4 du tampon 3 au travers de laquelle est monté à coulissement guidé le pêne 7. La lumière 29 débouche bien entendu dans l'espace défini entre les deux rampes 28 de l'ouverture 10 permettant le passage guidé du barreau 14 de la clef d'actionnement 9. Le rôle de la lumière 29 est de permettre à la tige 11 de la clef d'actionnement 9, une fois introduite au travers de l'ouverture 10, de pivoter elle-même dans un plan perpendiculaire au voile plan 3a du tampon 3.The opening 10 of the buffer 3 further comprises a slot or groove 29 opening into the thickness of the plane web 3a of the buffer 3, perpendicular to the ramps 28 and extending from the upper longitudinal side of one of these ramps. More specifically, the light 29 extends from the ramp 28 of the opening 10 located closest to the side wall 4 of the buffer 3 through which is slidably guided the bolt 7. The light 29 opens well heard in the space defined between the two ramps 28 of the opening 10 allowing the guided passage of the bar 14 of the actuating key 9. The role of the light 29 is to allow the rod 11 of the actuating key 9, once introduced through the opening 10, to pivot itself in a plane perpendicular to the plane web 3a of the buffer 3.

Le déverrouillage du pêne 7 à partir de sa position de verrouillage du tampon 3 dans le cadre 2 et l'extraction du tampon 3 de ce cadre s'opèrent comme suit.Unlocking the bolt 7 from its locking position of the buffer 3 in the frame 2 and the extraction of the buffer 3 of this frame are as follows.

Tout d'abord, comme représenté en figure 3, un opérateur saisit la clef d'actionnement 9 pour introduire successivement la partie d'extrémité 13 et le barreau 14 de la clef 9 au travers des deux rampes 28 de l'ouverture 10 qui guident le barreau 14 avant l'introduction de l'extrémité 13 dans l'orifice 25 du pêne 7.First, as represented in figure 3 , an operator grasps the actuating key 9 to successively introduce the end portion 13 and the bar 14 of the key 9 through the two ramps 28 of the opening 10 which guide the bar 14 before the introduction of the end 13 in the hole 25 of the bolt 7.

La figure 4 montre en partie à l'aide de la figure 3 que l'extrémité 13 de la clef 9 est ensuite introduite dans l'orifice 25 en ayant été guidée également par une partie du chanfrein supérieur circulaire 27 puis par une partie du chanfrein inférieur 27 de l'orifice 25 et que le barreau 14 se trouve en dessous du voile plan 3a du tampon 3 en étant en appui sur la partie plate 21 du pêne 7, la tige 11 de la clef 9 étant alors inclinée d'un angle sensiblement égal à l'angle d'inclinaison α ou β des rampes 28 ou du chanfrein circulaire supérieur 27 de l'orifice 25.The figure 4 shows in part using the figure 3 that the end 13 of the key 9 is then introduced into the orifice 25 having been guided also by a portion of the circular upper chamfer 27 and then by a portion of the lower chamfer 27 of the orifice 25 and that the bar 14 is located below the planar web 3a of the buffer 3 while bearing on the flat part 21 of the bolt 7, the rod 11 of the key 9 being then inclined at an angle substantially equal to the angle of inclination α or β of the ramps 28 or the upper circular chamfer 27 of the orifice 25.

Les figures 5 et 6 montrent ensuite que la clef d'actionnement 9 est pivotée par l'opérateur dans un plan perpendiculaire au voile plan 3a du tampon 3 dans le sens des aiguilles d'une montre relativement à ces figures pour permettre à l'extrémité libre 13 de la clef 9 d'entraîner en translation le pêne 7 à l'encontre de la force de rappel du ressort 22 pour désengager la partie plate 21 du pêne 7 de la gâche 8 du cadre 2 comme représenté en figure 7. Ce pivotement est autorisé par la lumière 29 dans laquelle peut se déplacer la partie correspondante de la tige 11 de la clef d'actionnement 9.The figures 5 and 6 then show that the actuating key 9 is pivoted by the operator in a plane perpendicular to the plane web 3a of the buffer 3 in the clockwise direction relative to these figures to allow the free end 13 of the key 9 to drive in translation the bolt 7 against the return force of the spring 22 to disengage the flat portion 21 of the bolt 7 of the keeper 8 of the frame 2 as shown in FIG. figure 7 . This pivoting is authorized by the light 29 in which the corresponding part of the rod 11 of the operating key 9 can move.

A la position déverrouillée du pêne 7 de sa gâche 8 de la figure 7, l'opérateur saisit la poignée 17 pour effectuer le coulissement vers le bas du fourreau 15 et de la clavette 16 jusqu'à introduire une partie du fourreau 15 et de la clavette 16 dans l'ouverture définie entre la rampe 28 située à côté de la nervure de renforcement 20 et l'extrémité de la lumière 29 opposée à cette rampe comme représenté en figure 8.In the unlocked position of the bolt 7 of its latch 8 of the figure 7 , the operator grasps the handle 17 to slide down the sleeve 15 and the key 16 to introduce a portion of the sleeve 15 and the key 16 into the defined opening between the ramp 28 located next to the reinforcing rib 20 and the end of the light 29 opposite this ramp as shown in FIG. figure 8 .

La figure 9 montre que l'ensemble à fourreau 15 et clavette 16 est situé à sa position la plus basse relativement à la tige 11 de la clef d'actionnement 9 et à laquelle l'extrémité inférieure de la clavette 16 est en appui sur la partie plate 21 du pêne 7.The figure 9 shows that the sleeve assembly 15 and key 16 is located at its lowest position relative to the rod 11 of the actuating key 9 and at which the lower end of the key 16 bears on the flat portion 21 of the bolt 7.

De la sorte, l'ensemble à fourreau 15 et clavette 16 bloque en toute sécurité la clef d'actionnement 9 à sa position sensiblement perpendiculaire au voile plan 3a du tampon 3 avec, bien entendu, le barreau 14 de la clef 9 situé sous le voile plan 3a de ce tampon. A partir de cette position de blocage de la clef 9 relativement au tampon 3, l'opérateur peut alors exercer une traction sur la clef d'actionnement 9 par l'intermédiaire de la poignée de manoeuvre 12 pour soulever le tampon 3 et le désengager complètement de son cadre de support 2.In this way, the sleeve assembly 15 and key 16 securely locks the operating key 9 at its position substantially perpendicular to the plane web 3a of the buffer 3 with, of course, the bar 14 of the key 9 located under the plane sail 3a of this buffer. From this locking position of the key 9 relative to the pad 3, the operator can then exert traction on the operating key 9 via the operating handle 12 to lift the pad 3 and disengage it completely. of its support frame 2.

Une fois le tampon 3 complètement extrait du cadre de support 2, la clef d'actionnement 9 peut rester bloquée relativement au tampon 3 à sa position représentée aux figures 9 et 10 à laquelle le pêne 9 est maintenu à sa position de déverrouillage. Dans ces conditions, lorsque l'opérateur souhaite repositionner le tampon à sa position de fermeture dans le cadre de support 2, il saisit alors la clef d'actionnement 9 pour soulever le tampon et le disposer au dessus du cadre 2. Ensuite, il relâche la clef d'actionnement 9 de façon que le tampon 3 s'encastre par gravité dans les parois 5 du cadre 2 pour obturer l'ouverture de ce dernier. L'opérateur saisit ensuite la poignée 17 en exerçant sur celle-ci une traction vers le haut pour faire coulisser le fourreau 15 le long de la tige 18 de la clef 9 et désengager le fourreau et la clavette 16 de l'orifice 10 et de la lumière 29 à la position représentée en figure 7, débloquant ainsi la clef 9 relativement au tampon 3. L'opérateur fait ensuite pivoter la clef d'actionnement 9 dans le sens inverse des aiguilles d'une montre par rapport aux figures 6 et 5 jusqu'à amener la clef 9 à sa position représentée en figure 3 à laquelle la clef peut être retirée du tampon 3 par coulissement guidé de l'extrémité 13 et du barreau 14 par les chanfreins circulaires 27 de l'orifice 25 et les rampes 28 du tampon 3, permettant ainsi au pêne 7, sous l'action du ressort 22, de revenir à sa position de verrouillage dans la gâche 8 du cadre 2 pour verrouiller le tampon 3 dans ce cadre.Once the buffer 3 is completely extracted from the support frame 2, the operating key 9 can remain locked relative to the buffer 3 at its position shown in FIGS. figures 9 and 10 to which the bolt 9 is held in its unlocking position. Under these conditions, when the operator wishes to reposition the buffer to its closed position in the support frame 2, he then grasps the actuating key 9 to lift the buffer and arrange it above the frame 2. Then, he releases the actuating key 9 so that the buffer 3 fits by gravity in the walls 5 of the frame 2 to close the opening of the latter. The operator then grasps the handle 17 by exerting on it an upward pull to slide the sleeve 15 along the shank 18 of the key 9 and disengage the sheath and the key 16 from the orifice 10 and the light 29 at the position shown in figure 7 , thus unlocking the key 9 relative to the buffer 3. The operator then rotates the operating key 9 counterclockwise in relation to the figures 6 and 5 to bring the key 9 to its position represented in figure 3 to which the key can be removed from the pad 3 by guided sliding of the end 13 and the bar 14 by the circular chamfers 27 of the orifice 25 and the ramps 28 of the pad 3, thereby allowing the bolt 7, under the action of the spring 22, to return to its locking position in the keeper 8 of the frame 2 to lock the buffer 3 in this frame.

Une autre possibilité pour repositionner le tampon 3 à sa position de fermeture dans son cadre de support 2 consiste au préalable à débloquer la clef d'actionnement 9 du tampon 3 en agissant sur la poignée 17 pour retirer le fourreau 15 et la clavette 16 de l'ouverture 10 et de sa lumière 29 puis à faire pivoter la clef d'actionnement 9 dans son plan perpendiculaire au voile 3a du tampon 3 jusqu'à sa position à laquelle la clef 9 peut être complètement retirée du tampon 3 comme expliqué précédemment. Ensuite, l'opérateur peut saisir le tampon 3 au besoin à l'aide d'au moins un outil approprié engagé dans un perçage correspondant 30 du tampon 3 pour soulever ce dernier et le placer au dessus du cadre de support 2. En relâchant le tampon 3, ce dernier tombe par gravité dans le cadre 2 et pendant cette chute, la paroi latérale correspondante 5 du cadre 2 exerce sur l'extrémité libre de la partie plate 21 du pêne 7 un effort repoussant ce dernier à l'encontre de la force de rappel du ressort 22 jusqu'à ce que cette extrémité libre se trouve en regard de la gâche 8 dans laquelle cette extrémité est introduite à la position définitive de fermeture du tampon 3 dans le cadre 2. Le tampon 3 est alors verrouillé par le pêne 7 relativement au cadre 2.Another possibility for repositioning the buffer 3 in its closed position in its support frame 2 is to first unlock the operating key 9 of the buffer 3 by acting on the handle 17 to remove the sleeve 15 and the key 16 of the opening 10 and its light 29 and then pivoting the actuating key 9 in its plane perpendicular to the web 3a of the buffer 3 to its position to which the key 9 can be completely removed from the buffer 3 as explained above. Then, the operator can enter the pad 3 if necessary using at least one suitable tool engaged in a corresponding bore 30 of the pad 3 to lift the latter and place it above the support frame 2. By releasing the buffer 3, the latter falls by gravity in the frame 2 and during this fall, the corresponding side wall 5 of the frame 2 exerts on the free end of the flat portion 21 of the bolt 7 a force pushing the latter against the restoring force of the spring 22 until this free end is opposite the striker 8 in which this end is introduced to the final position of closure of the buffer 3 in the frame 2. The buffer 3 is then locked by the bolt 7 relative to frame 2.

Le dispositif de verrouillage et de déverrouillage ci-dessus décrit peut s'appliquer non seulement à un tampon de forme rectangulaire, mais également à un tampon de forme triangulaire ou circulaire.The locking and unlocking device described above can be applied not only to a rectangular shaped pad, but also to a triangular or circular pad.

Le dispositif ci-dessus décrit de l'invention est non seulement d'une structure extrêmement simple mais permet à un opérateur par un simple pivotement de la clef d'actionnement dans un plan perpendiculaire au plan du tampon d'opérer facilement le déverrouillage du pêne solidarisant le tampon dans son cadre de support. En outre, la clef d'actionnement peut être bloquée en toute sécurité relativement au tampon 3 à une position maintenant le pêne à sa position de déverrouillage.The above described device of the invention is not only of an extremely simple structure but allows an operator by a simple pivoting of the actuating key in a plane perpendicular to the plane of the buffer to easily operate the unlocking of the bolt solidarisant the buffer in its support frame.
