Description

La présente invention concerne un dispositif de verrouillage et de déverrouillage à l'aide d'une clé d'un tampon ou couvercle sur un cadre, notamment de regard de chaussée.The present invention relates to a device for locking and unlocking with the aid of a key of a buffer or cover on a frame, especially a manhole.

On connaît par le document FR 2 898 614 un tel dispositif comprenant un verrou solidaire du tampon qui présente une ouverture débouchante d'accès au verrou pour la clé comportant un bras dont une extrémité permet de manoeuvrer le verrou lorsque la clé est introduite dans l'ouverture du tampon d'une position de verrouillage dans laquelle un pêne de verrou est retenu prisonnier d'une gâche du cadre à une position de déverrouillage pour laquelle le pêne est dégagé de la gâche.We know from the document FR 2,898,614 such a device comprising a lock integral with the buffer which has an opening opening access to the lock for the key having an arm whose one end allows to operate the lock when the key is inserted into the opening of the buffer of a locking position wherein a latch bolt is held prisoner of a striker of the frame to an unlocking position for which the bolt is released from the striker.

Ce verrou comprend un rotor monté à rotation dans le tampon, accessible à l'une de ses extrémités par l'ouverture débouchante et portant le pêne à son extrémité opposée de manière à permettre le pivotement du pêne autour de l'axe longitudinal de rotor sous l'action de la clé, lorsque son extrémité est en prise avec l'extrémité correspondante du rotor, entre ses positions prisonnière et dégagée de la gâche.This lock comprises a rotor rotatably mounted in the buffer, accessible at one of its ends through the opening opening and carrying the bolt at its opposite end so as to allow the bolt to pivot about the longitudinal rotor axis under the action of the key, when its end is engaged with the corresponding end of the rotor, between its positions prisoner and released from the striker.

Ce dispositif connu, tout comme d'ailleurs d'autres dispositifs connus de verrouillage et de déverrouillage à l'aide d'une clé d'un tampon sur un cadre, a pour inconvénient que des détritus peuvent passer dans l'ouverture débouchante du tampon pouvant atteindre certains des composants internes du verrou, pouvant conduire à rendre difficile le pivotement par la clé du pêne de sa position de verrouillage du tampon au cadre à sa position de déverrouillage de ce tampon du cadre. En outre, à la longue, les détritus peuvent s'accumuler dans l'ouverture débouchante et complètement l'obstruer, empêchant ainsi l'introduction de la clé dans l'ouverture débouchante du tampon pour manoeuvrer le pêne du verrou.This known device, as well as other known devices for locking and unlocking with a key of a buffer on a frame, has the disadvantage that detritus can pass into the opening opening of the buffer which can reach some of the internal components of the lock, which can lead to difficult pivoting by the bolt key from its locked position of the frame buffer to its unlocked position of the frame buffer. In addition, in the long run, debris can accumulate in the opening opening and completely obstruct it, thus preventing the introduction of the key in the opening opening of the buffer to manipulate the latch bolt.

Pour résoudre un tel problème, une solution consiste à obturer l'ouverture débouchante de tampon par un bouchon amovible. Cependant, cette solution a pour inconvénient que le bouchon peut être égaré après avoir été retiré lors d'une manoeuvre du verrou à sa position de déverouillage du tampon du cadre ou tout simplement dérobé par une personne mal intentionnée.To solve such a problem, one solution is to close the opening opening of the buffer by a removable plug. However, this solution disadvantage that the cap can be lost after being removed during a maneuver of the lock to its unlocking position of the frame buffer or simply stolen by a malicious person.

Le document DE 10 2004 063048 décrit un dispositif de verrouillage et de déverrouillage à l'aide d'une clé d'un couvercle à un cadre. Lorsque l'extrémité de la clé est introduite dans une ouverture débouchante du dispositif, elle vient en appui sur une plaque mobile axialement qui est déplacée par enfoncement de la clé à l'encontre de la force de rappel d'un ressort pour mettre en prise la clé avec l'extrémité supérieure d'un rotor à pêne de verrouillage.The document DE 10 2004 063048 discloses a locking and unlocking device using a key of a cover to a frame. When the end of the key is inserted into an opening opening of the device, it bears on an axially movable plate which is moved by depressing the key against the restoring force of a spring to engage the key with the upper end of a locking bolt rotor.

Le dispositif de verrouillage et de déverrouillage de l'invention qui va être décrit ci-dessous est tout particulièrement destiné à équiper un tampon ou couvercle 1 permettant d'obturer un cadre ou châssis 2 délimitant l'ouverture notamment d'un regard de chaussée.The locking and unlocking device of the invention which will be described below is particularly intended to equip a buffer or cover 1 for closing a frame or frame 2 defining the opening including a manhole.

Le dispositif de verrouillage et de déverrouillage peut être actionné par une clé 3 comme on le verra ultérieurement.The locking and unlocking device can be actuated by a key 3 as will be seen later.

Le tampon a sa paroi supérieure sensiblement plane la comportant une ouverture 4 débouchant d'une part vers l'extérieur au niveau d'une face supérieure plane 1b de cette paroi et d'autre part dans une cavité interne 5 du tampon 1 dans laquelle est logée une partie d'un verrou 6 auquel la clé 3 peut accéder au travers de l'ouverture débouchante 4.The buffer has its substantially flat upper wall having an opening 4 opening on the one hand outwardly at a flat upper face 1b of this wall and on the other hand in an internal cavity 5 of the buffer 1 in which is housed part of a lock 6 to which the key 3 can access through the opening opening 4.

La clé 3 comprend un bras longitudinal 7 dont une extrémité est pourvue d'une douille 8 coaxiale au bras 7 et une poignée de manoeuvre 9 solidaire de l'extrémité opposée du bras 7 perpendiculairement à celui-ci. La douille 8 comporte une empreinte interne 10 permettant d'être en prise avec un rotor 11 monté à rotation dans la cavité interne 5 pour manoeuvrer le verrou 6 d'une position de verrouillage dans laquelle un pêne 12 du verrou 6 est retenu prisonnier d'une gâche 13 du cadre 2 pour verrouiller le tampon 1 au cadre 2 à une position de déverrouillage pour laquelle le pêne 12 est dégagé de la gâche 13 pour permettre le retrait du tampon 1 du cadre 2.The key 3 comprises a longitudinal arm 7 whose one end is provided with a bushing 8 coaxial with the arm 7 and an operating handle 9 integral with the opposite end of the arm 7 perpendicular to it. The sleeve 8 has an internal imprint 10 allowing to be in engagement with a rotor 11 rotatably mounted in the internal cavity 5 to operate the latch 6 of a locking position in which a bolt 12 of the latch 6 is held prisoner of a latch 13 of the frame 2 to lock the latch buffer 1 to the frame 2 to an unlocking position for which the bolt 12 is released from the striker 13 to allow the removal of the buffer 1 of the frame 2.

Le rotor 11 comporte, solidaire de son extrémité opposée à celle destinée à venir en prise avec la douille 8 de la clé 3, le pêne 12 constitué par un bras plat sensiblement rectangulaire parallèle à la paroi supérieure la du tampon 1 à une certaine distance de celle-ci et pouvant tourner conjointement avec le rotor 11 pour occuper sa position à laquelle il est retenu prisonnier de la gâche 13 du cadre 2 ou sa position à laquelle il est désengagé de cette gâche.The rotor 11 comprises, integral with its end opposite to that intended to engage with the socket 8 of the key 3, the bolt 12 constituted by a substantially rectangular flat arm parallel to the upper wall 1a of the buffer 1 at a certain distance from it can rotate together with the rotor 11 to occupy its position to which it is held prisoner of the striker 13 of the frame 2 or its position to which it is disengaged from the striker.

Selon l'invention, le rotor 11 du verrou 6 s'étend perpendiculairement à la paroi supérieure la du tampon 1 sous celle-ci en traversant la cavité interne 5 et une paroi de fond 14 d'un boîtier 15 délimitant la cavité 5 avec sa paroi latérale 16 solidaire de la face interne plane 1c du tampon 1. La partie d'extrémité 11a du rotor 11 portant le pêne 12 fait saillie avec ce dernier en dehors de la paroi de fond 14 du boîtier 15 au travers d'une ouverture circulaire 17 de cette paroi.According to the invention, the rotor 11 of the latch 6 extends perpendicularly to the upper wall 1a of the buffer 1 beneath it while passing through the internal cavity 5 and a bottom wall 14 of a housing 15 delimiting the cavity 5 with its side wall 16 integral with the flat inner face 1c of the buffer 1. The end portion 11a of the rotor 11 carrying the bolt 12 projects therefrom outside the bottom wall 14 of the housing 15 through a circular opening 17 of this wall.

Le rotor 11 est fixé axialement relativement au tampon 1 de manière que sa partie extrémité 11b soit logée coaxialement dans l'ouverture débouchante 4 avec sa face en bout plane 11c en affleurement avec la face plane supérieure 1b de la paroi la de ce tampon.The rotor 11 is fixed axially relative to the pad 1 so that its end portion 11b is housed coaxially in the opening opening 4 with its flat end face 11c flush with the upper planar face 1b of the wall 1a of this buffer.

En outre, l'ouverture débouchante 4 du tampon 1 est obturée, lorsque le pêne 12 du verrou 6 occupe sa position de verrouillage du tampon au cadre 2, par un bouchon 18 disposé concentriquement à la partie d'extrémité 11b du rotor 11 et dont une partie d'extrémité 19 est logée dans l'ouverture débouchante 4 autour de la partie d'extrémité 11b du rotor 11 et de forme complémentaire à celle de l'ouverture débouchante 4 de manière à obturer la partie restante d'ouverture située entre l'ouverture 4 et la partie d'extrémité 11b du rotor 11. Selon l'invention, la partie d'extrémité 19 du bouchon 18, lorsque ce dernier occupe sa position d'obturation de l'ouverture débouchante 4, a sa face plane en bout 19c en affleurement avec la face en bout 11c du rotor 11 et la face supérieure plane 1b du tampon 1.In addition, the opening opening 4 of the buffer 1 is closed, when the bolt 12 of the latch 6 occupies its locking position of the buffer frame 2, by a plug 18 arranged concentrically at the end portion 11b of the rotor 11 and an end portion 19 is housed in the opening opening 4 around the end portion 11b of the rotor 11 and of complementary shape to that of the opening opening 4 so as to close the remaining portion of opening located between the opening 4 and the end portion 11b of the rotor 11. According to the invention, the end portion 19 of the plug 18, when the latter occupies its closed position of the opening opening 4, has its flat end face 19c flush with the end face 11c of the rotor 11 and the flat upper face 1b of the buffer 1.

De préférence, le bouchon 18 est constitué par un tronçon cylindrique dont une partie est constituée par la partie d'extrémité 19 et l'autre partie d'extrémité 20 est logée dans la cavité interne 5.Preferably, the plug 18 is constituted by a cylindrical section, part of which is constituted by the end portion 19 and the other end portion 20 is housed in the internal cavity 5.

Le bouchon 18 comporte une collerette 21 située entre les deux parties de tronçons cylindriques 19, 20 et disposée en appui, à la position de fermeture du bouchon 18, sur une face plane annulaire interne 1d de la paroi la du tampon 1 délimitant avec la face plane supérieure 1b l'ouverture débouchante 4.The plug 18 comprises a collar 21 located between the two portions of cylindrical sections 19, 20 and disposed in abutment, at the closed position of the plug 18, on an inner annular flat face 1d of the wall 1a of the buffer 1 delimiting with the face upper plane 1b opening opening 4.

Le bouchon 18 est maintenu à sa position de fermeture de l'ouverture débouchante 4 par un ressort de rappel 22 du type hélicoïdal de compression, monté précontraint entre la collerette 21 du bouchon 18 et une bague 23 formant palier de guidage en rotation de la partie d'extrémité 11a du rotor 11, la bague 23 étant logée et solidarisée dans le boîtier 15 du tampon 1.The plug 18 is held in its closed position of the opening opening 4 by a return spring 22 of the helical compression type, mounted prestressed between the collar 21 of the plug 18 and a ring 23 forming a guide bearing in rotation of the part end 11a of the rotor 11, the ring 23 being housed and secured in the housing 15 of the buffer 1.

La partie d'extrémité 11a inférieure du rotor 11 est raccordée à la partie d'extrémité supérieure 11b par un épaulement 11d maintenu axialement en appui sur la bague en palier 23 comme on le verra ultérieurement.The lower end portion 11a of the rotor 11 is connected to the upper end portion 11b by a shoulder 11d held axially supported on the bearing ring 23 as will be seen later.

Le bouchon 18 peut être axialement déplacé de façon guidée le long de la partie d'extrémité 11b du rotor 11 à l'encontre la force de rappel du ressort 22 lorsque la douille 8 de la clé 3 est introduite au travers de l'ouverture débouchante.The plug 18 can be axially guidedly displaced along the end portion 11b of the rotor 11 against the restoring force of the spring 22 when the socket 8 of the key 3 is introduced through the opening opening .

A cet effet, le bouchon de fermeture 18 a son orifice traversant 24 de forme complémentaire à la forme externe de la partie d'extrémité 11b du rotor 11.For this purpose, the closure cap 18 has its through orifice 24 of complementary shape to the external shape of the end portion 11b of the rotor 11.

Plus particulièrement, la partie d'extrémité 11b du rotor 11 comporte un méplat 11e s'étendant tout le long de la partie d'extrémité 11b et pouvant coopérer avec un méplat 24a de l'orifice traversant 24 du bouchon 18.More particularly, the end portion 11b of the rotor 11 has a flattening 11e extending along the end portion 11b and being able to cooperate with a flat portion 24a of the through-orifice 24 of the plug 18.

En outre, la partie d'extrémité 11b du rotor 11 comporte un second méplat 11f de largeur moindre que celle du méplat 11e, raccordé à ce dernier et constituant un détrompeur coopérant avec un second méplat 24b de l'orifice 24 du bouchon 18.In addition, the end portion 11b of the rotor 11 has a second flat 11f of smaller width than that of the flat 11e, connected thereto and constituting a polarizer cooperating with a second flat 24b of the orifice 24 of the plug 18.

Ainsi, le bouchon 18 peut coulisser axialement le long du rotor 11 à l'encontre de la force de rappel 22 en étant solidarisé en rotation à la partie d'extrémité 11b.Thus, the plug 18 can slide axially along the rotor 11 against the restoring force 22 being secured in rotation to the end portion 11b.

Le bouchon 18 comprend deux tenons diamétralement opposés 25 engagés, en position de fermeture de ce bouchon, respectivement dans deux rainures ou entailles diamétralement opposées 4a de l'ouverture débouchante 4. Les deux rainures 4a débouchent dans l'orifice central circulaire 4b de l'ouverture débouchante 4. Les deux tenons 25 font saillie de la partie de tronçon 19 du bouchon 18 et présentent un diamètre externe égal au diamètre externe de la collerette 21.The plug 18 comprises two diametrically opposed posts 25 engaged, in the closed position of this plug, respectively in two diametrically opposite grooves or notches 4a of the opening opening 4. The two grooves 4a open into the circular central orifice 4b of the opening opening 4. The two tenons 25 protrude from the portion of section 19 of the plug 18 and have an outer diameter equal to the outer diameter of the collar 21.

De la sorte, en position de fermeture du bouchon 18 les deux tenons 25 et la partie de tronçon 19, de forme complémentaire à celle de l'ouverture débouchante 4, obturent complètement cette dernière autour de la partie d'extrémité 11b du rotor 11, et leurs faces en bouts respectives constituent la face en bout 19c qui est en affleurement avec la face en bout 11c du rotor 11 et la face plane supérieure 1b du tampon 1 en position de fermeture de ce bouchon.In this way, in the closed position of the plug 18, the two tenons 25 and the portion of section 19, of a shape complementary to that of the opening opening 4, completely close this latter around the end portion 11b of the rotor 11, and their respective end faces constitute the end face 19c which is flush with the end face 11c of the rotor 11 and the upper planar face 1b of the buffer 1 in the closed position of this plug.

L'empreinte 10 de la douille 8 de la clé 3 est de forme complémentaire à celle de la partie d'extrémité 11b du rotor 11, c'est-à-dire que l'empreinte 10 comporte un méplat 10a apte à coopérer avec le méplat 11e de la partie d'extrémité 11b du rotor 11 et un second méplat de plus faible largeur 10b apte à coopérer avec le méplat 11f de la partie d'extrémité 11b pour constituer ensemble un moyen détrompeur.The impression 10 of the socket 8 of the key 3 is of complementary shape to that of the end portion 11b of the rotor 11, that is to say that the imprint 10 comprises a flat part 10a able to cooperate with the flattened 11th of the end portion 11b of the rotor 11 and a second flat of smaller width 10b adapted to cooperate with the flat portion 11f of the end portion 11b together to form a polarizing means.

La douille 8 de la clé 3 comporte deux ergots diamétralement opposés 26 faisant saillie de part et d'autre de la douille 8 et de forme conjuguée respectivement aux deux rainures diamétralement opposées 4a de l'ouverture débouchante 4. La douille 8 a un diamètre externe d'un diamètre sensiblement égal au diamètre externe de la partie de tronçon 19 du bouchon 18 et les deux ergots 26 de la douille 8 sont de forme identique aux deux tenons 25 du bouchon 18, le diamètre externe de la douille 8 étant légèrement inférieur au diamètre de la partie débouchante 4.The socket 8 of the key 3 has two diametrically opposed lugs 26 projecting on either side of the bushing 8 and of shape respectively conjugate to the two diametrically opposite grooves 4a of the opening opening 4. The bushing 8 has an outer diameter a diameter substantially equal to the outer diameter of the section portion 19 of the plug 18 and the two lugs 26 of the sleeve 8 are of identical shape to the two pins 25 of the plug 18, the outer diameter of the sleeve 8 being slightly less than the diameter of the opening part 4.

La bague formant palier 23 comporte deux ergots radialement externes et diamétralement opposés 27 s'engageant, lors du montage des composants du verrou dans le boîtier 15, respectivement dans deux rainures ou entailles diamétralement opposées 28 réalisées au travers de la paroi de fond 14 du boîtier 15. La bague formant palier 23 est enfilée sur une portion cylindrique de la partie d'extrémité 11a du rotor 11 raccordée à l'épaulement 11d de ce rotor et la bague 23, une fois sa face en regard du bouchon 18 amenée en appui sur l'épaulement 11d, est tournée d'environ un quart de tour pour disposer les deux ergots 27 en appui sur la face interne correspondante 14a de la paroi de fond 14 du boîtier 15, le ressort 22 exerçant un effort axial de maintien des deux ergots 27 sur cette face interne. Ainsi, la bague formant palier 23 est amoviblement fixée dans la cavité interne 5 du boîtier 15.The bearing ring 23 has two radially outer and diametrically opposite lugs 27 engaging, when mounting the latch components in the housing 15, respectively in two diametrically opposite grooves or slots 28 made through the bottom wall 14 of the housing 15. The bearing ring 23 is threaded onto a cylindrical portion of the end portion 11a of the rotor 11 connected to the shoulder 11d of this rotor and the ring 23, once its face facing the plug 18 brought to bear on the shoulder 11d is turned about a quarter of a turn to arrange the two lugs 27 resting on the corresponding inner face 14a of the bottom wall 14 of the housing 15, the spring 22 exerting an axial force for holding the two lugs 27 on this inner side. Thus, the bearing ring 23 is removably fixed in the internal cavity 5 of the casing 15.

Le bras plat constituant le pêne 12 est enfilé sur la partie d'extrémité 11a du rotor 11 au-dessus de la bague formant palier 23 en considérant la figure 13 et est solidarisé en rotation à cette partie d'extrémité par un méplat 29a d'un orifice traversant 29 de ce bras coopérant avec un méplat 11g de la partie d'extrémité 11a du rotor 11.The flat arm constituting the bolt 12 is threaded on the end portion 11a of the rotor 11 above the bearing ring 23 by considering the figure 13 and is secured in rotation to this end portion by a flat portion 29a of a through orifice 29 of this arm cooperating with a flat portion 11g of the end portion 11a of the rotor 11.

Le bras du pêne 12 est fixé axialement à la partie d'extrémité 11a du rotor 11 par une goupille fendue 30 traversant un perçage 11h de la partie d'extrémité 11a du rotor avec interposition entre la goupille 30 et le bras de pêne 12 de deux rondelles coniques 31 enfilées sur la partie d'extrémité 11a.The arm of the bolt 12 is fixed axially to the end portion 11a of the rotor 11 by a cotter pin 30 passing through a bore 11h of the end portion 11a of the rotor with interposition between the pin 30 and the bolt arm 12 of two conical washers 31 threaded on the end portion 11a.

Une rondelle élastique ou ressort 32 est enfilée sur la partie d'extrémité 11a du rotor 11 et est interposée entre la bague formant palier 23 et le bras du pêne 12 pour exercer un effort axial sur le rotor 11 le maintenant axialement en appui sur la bague formant palier 23 par son épaulement 11d, solidarisant ainsi axialement le rotor 11 relativement au tampon 1.An elastic washer or spring 32 is threaded onto the end portion 11a of the rotor 11 and is interposed between the bearing ring 23 and the arm of the bolt 12 to exert an axial force on the rotor 11 keeping it axially bearing on the ring forming a bearing 23 by its shoulder 11d, thereby axially securing the rotor 11 relative to the buffer 1.

De préférence, la rondelle élastique 32 est constituée par une rondelle à deux ondulations centrales d'un même côté constituant deux ergots 32a engagés respectivement dans deux entailles diamétralement opposées 33 de la bague formant palier 23 pour que la rondelle 32 exerce une poussée axiale sur le pêne 12.Preferably, the elastic washer 32 is constituted by a washer with two central corrugations on the same side constituting two lugs 32a respectively engaged in two diametrically opposite cutouts 33 of the bearing ring 23 so that the washer 32 exerts an axial thrust on the bolt 12.

Selon une variante non représentée, la rondelle 32 pourrait être tout simplement constituée en un matériau élastomère compressible élastiquement en direction axiale.According to a variant not shown, the washer 32 could be simply made of a resiliently compressible elastomeric material in the axial direction.

La paroi de fond 14 du boîtier 15 comporte deux butées 34 externes au boîtier 15 et destinées à délimiter le pivotement du pêne 12 entre ses deux positions extrêmes de verrouillage du tampon 1 au cadre 2 et de déverrouillage de ce tampon du cadre.The bottom wall 14 of the housing 15 has two stops 34 external to the housing 15 and intended to define the pivoting of the bolt 12 between its two extreme positions of locking the buffer 1 to the frame 2 and unlocking the frame buffer.

Le montage des différents composants décrits ci-dessus du verrou 6 situés en grande partie dans le boîtier 15 du tampon 1 s'effectue comme suit.The assembly of the various components described above of the lock 6 located largely in the housing 15 of the buffer 1 is as follows.

Tout d'abord, le tampon 1 est retourné de manière que sa face supérieure 1b soit en appui sur le sol ou tout autre support plat (figure 13).Firstly, the pad 1 is turned over so that its upper face 1b bears against the ground or any other flat support ( figure 13 ).

Ensuite, le bouchon 18 est logé dans la cavité interne 5 en introduisant ses deux tenons 25 respectivement dans les deux rainures 4a de l'ouverture débouchante 4 jusqu'à ce que sa collerette 21 vienne en appui sur la face annulaire correspondante 1d de la paroi la du tampon 1.Then, the plug 18 is housed in the internal cavity 5 by introducing its two tenons respectively into the two grooves 4a of the opening opening 4 until its flange 21 bears on the corresponding annular face 1d of the wall the buffer 1.

Le rotor 11 est ensuite positionné dans le bouchon 18 par introduction de ses deux méplats 11e, 11f respectivement dans les deux méplats 24a, 24b du bouchon 18 et le ressort 22 est alors enfilé sur le rotor 11 et la partie de tronçon 20 du bouchon 18 avec la spire extrême de ce ressort en appui sur la collerette 21 du bouchon 18.The rotor 11 is then positioned in the plug 18 by introducing its two flats 11e, 11f respectively into the two flats 24a, 24b of the plug 18 and the spring 22 is then threaded onto the rotor 11 and the portion 20 of the plug portion 18 with the extreme turn of this spring resting on the collar 21 of the stopper 18.

Ensuite, la bague formant palier 23 est mise en place dans la paroi 14 en introduisant ses deux ergots 27 respectivement dans les deux rainures ou encoches 28 de la paroi 14 et une pression axiale est ensuite exercée sur la bague formant palier 23 en comprimant le ressort 22 jusqu'à ce que la bague 23 vienne en appui sur l'épaulement 11d du rotor 11 et la bague est alors tournée d'environ un quart de tour pour mettre les deux ergots 27 en appui sur la face interne correspondante 14a de la paroi 14, verrouillant ainsi la bague 23 dans le boîtier 15 du tampon 1.Then, the bearing ring 23 is placed in the wall 14 by introducing its two lugs 27 respectively in the two grooves or notches 28 of the wall 14 and an axial pressure is then exerted on the bearing ring 23 by compressing the spring 22 until the ring 23 bears on the shoulder 11d of the rotor 11 and the ring is then rotated about a quarter of a turn to put the two lugs 27 against the corresponding inner face 14a of the wall 14, thus locking the ring 23 in the housing 15 of the buffer 1.

De la sorte, l'ensemble à bouchon 18, rotor 11, ressort 22 et bague formant palier 23 est logé dans la cavité interne 5 et maintenu axialement dans le boîtier 15.In this way, the cap assembly 18, rotor 11, spring 22 and bearing ring 23 is housed in the internal cavity 5 and axially held in the housing 15.

Ensuite, la rondelle 32 est enfilée sur la partie d'extrémité 11a du rotor 11 en venant en appui sur la bague formant palier 23 et le pêne de verrouillage 12 est également enfilé sur la partie d'extrémité 11a en engageant le méplat 29a de son orifice 29 avec le méplat 11g de la partie d'extrémité 11a du rotor 11. La rondelle 32 est alors logée dans le boîtier 15 mais le pêne 12 et la portion restante de la partie d'extrémité 11a du rotor 11 sont à l'extérieur de ce boîtier.Then, the washer 32 is threaded onto the end portion 11a of the rotor 11 bearing on the bearing ring 23 and the locking bolt 12 is also threaded on the end portion 11a by engaging the flat portion 29a of its orifice 29 with the flat portion 11g of the end portion 11a of the rotor 11. The washer 32 is then housed in the housing 15 but the bolt 12 and the remaining portion of the end portion 11a of the rotor 11 are outside of this case.

Les deux rondelles coniques 31 sont enfilées sur la partie d'extrémité 11a du rotor 11 faisant saillie du pêne 12 et la goupille 30 est engagée à travers le perçage 11h de la partie d'extrémité 11a en comprimant élastiquement la rondelle 32 entre le pêne 12 et la bague formant palier 23.The two conical washers 31 are threaded onto the end portion 11a of the rotor 11 projecting from the bolt 12 and the pin 30 is engaged through the bore 11h of the end portion 11a by resiliently compressing the washer 32 between the bolt 12 and the bearing ring 23.

Une fois le verrou de l'invention installé dans le boîtier 15, il suffit de retourner le tampon 1 pour l'appliquer sur le cadre 2 et le bouchon 18 obture alors pratiquement de manière hermétique l'orifice débouchant 4 de ce tampon.Once the lock of the invention installed in the housing 15, simply return the buffer 1 to apply it to the frame 2 and the plug 18 then substantially hermetically closes the opening 4 opening of this buffer.

Le fonctionnement du verrou de l'invention pour déverrouiller le tampon 1 du cadre 2 va être maintenant expliqué.The operation of the lock of the invention to unlock the buffer 1 of the frame 2 will now be explained.

A la position de verrouillage du tampon 1 au cadre 2, le pêne 12 occupe sa position à laquelle il est prisonnier de la gâche 13 du cadre 2 en étant en appui sur l'une des deux butées 34 du boîtier 15 comme représenté aux figures 1 à 4.At the locking position of the buffer 1 to the frame 2, the bolt 12 occupies its position in which it is trapped by the striker 13 of the frame 2 while being supported on one of the two abutments 34 of the housing 15 as shown in FIGS. Figures 1 to 4 .

Les figures 5 à 9 montrent qu'un opérateur a positionné la clé 3 au-dessus de l'ouverture débouchante 4 de manière que les deux ergots 26 de la douille 8 de cette clé soient disposés en aplomb des deux rainures conjuguées 4a de l'ouverture débouchante 4 et que les deux méplats 10a, 10b de l'empreinte 10 de la douille 8 soient disposés en regard respectivement des méplats 11e et 11f du rotor 11.The Figures 5 to 9 show that an operator has positioned the key 3 above the opening opening 4 so that the two lugs 26 of the socket 8 of this key are disposed vertically above the two conjugate grooves 4a of the opening opening 4 and that the two flats 10a, 10b of the recess 10 of the bushing 8 are arranged respectively opposite flats 11e and 11f of the rotor 11.

A la position représentée ci-dessus de la clé 3, l'opérateur exerce alors une pression verticale sur la clé 3 pour accoupler par les méplats 10a, 10b et 11e, 11f la clé 3 au rotor 11 et enfoncer le bouchon 18 dans la cavité interne 5 à l'encontre de la force de rappel du rotor 22 jusqu'à ce que le bouchon 18 soit disposé pratiquement au-dessus de la bague formant palier 23 de manière à disposer les deux ergots 26 de la clé 3 en dessous de la face interne inférieure 1d de la paroi la du tampon 1. La clé 3 est tournée d'environ un quart de considérant notamment la figure 4 de manière à faire pivoter le pêne 12 de sa position de verrouillage représentée en figure 4 à sa position de déverrouillage représentée en figure 11 et amener les deux ergots 26 de la clé 3 sous la face interne 1d du tampon 1, ces ergots étant maintenus sous cette face par la force de rappel exercée par le ressort 22 et le bouchon 18 sur les deux ergots 26. De la sorte, la clé 23 est emprisonnée dans la cavité interne 5 du tampon 1 et permet la manipulation de celui-ci pour le soulever sans risque de perte de la clé 3 une fois le tampon 1 complètement désengagé du cadre 2.In the position shown above of the key 3, the operator then exerts a vertical pressure on the key 3 to couple by the flats 10a, 10b and 11e, 11f the key 3 to the rotor 11 and push the plug 18 into the cavity 5 against the return force of the rotor 22 until the plug 18 is disposed substantially above the bearing ring 23 so as to arrange the two lugs 26 of the key 3 below the lower inner face 1d of the wall 1a of the buffer 1. The key 3 is turned about a quarter of whereas, in particular, figure 4 so as to rotate the bolt 12 from its locking position shown in figure 4 at its unlocked position represented in figure 11 and bring the two lugs 26 of the key 3 under the inner face 1d of the buffer 1, these lugs being held under this face by the restoring force exerted by the spring 22 and the plug 18 on the two lugs 26. In this way, the key 23 is trapped in the internal cavity 5 of the buffer 1 and allows the manipulation thereof to raise it without risk of losing the key 3 once the buffer 1 completely disengaged from the frame 2.

Pour verrouiller à nouveau le tampon 1 au cadre 2, après avoir disposé le tampon 1 sur ce cadre, la clé 3 est manoeuvrée dans le sens inverse des aiguilles d'une montre en considérant les figures 10 et 11 d'environ un quart de tour pour amener les deux ergots 26 de la clé 3 en regard respectivement des deux rainures 4a de l'ouverture débouchante 4 et le ressort 22 se détend pour exercer sur le bouchon 18 un effort faisant coulisser ce bouchon vers le haut le long du rotor 11 pour le ramener à sa position notamment de la figure 9 à laquelle il obture à nouveau avec la partie d'extrémité 11b du rotor 11 l'ouverture débouchante 4, le ressort 22 ramènant la douille 8 et ses ergots 26 au-dessus de la face supérieure plane 1b du tampon 1 pour permettre à l'opérateur de récupérer la clé 3.To lock the buffer 1 again to the frame 2, after having disposed the buffer 1 on this frame, the key 3 is operated counterclockwise by considering the Figures 10 and 11 about a quarter of a turn to bring the two lugs 26 of the key 3 respectively facing the two grooves 4a of the opening opening 4 and the spring 22 relaxes to exert on the plug 18 a force sliding the plug towards the up along the rotor 11 to bring it back to its position including the figure 9 to which it closes again with the end portion 11b of the rotor 11 the opening opening 4, the spring 22 returning the sleeve 8 and its lugs 26 above the flat upper face 1b of the buffer 1 to allow the operator to retrieve the key 3.

Les figures 2 et 8 montrent que le tampon 1 est monté pivotant, à l'opposé du dispositif de verrouillage, autour d'un axe d'articulation A comme cela est connu en soi pour retenir le tampon 1 au cadre 2 lorsque le tampon 1 occupe sa position relevée debout de dégagement de l'ouverture du cadre 2. Cependant, l'articulation du tampon 1 au cadre 2 peut être du type permettant le retrait du tampon 1 de ce cadre à la position relevée debout du tampon 1.The figures 2 and 8 show that the buffer 1 is pivotally mounted, opposite the locking device, around a hinge axis A as is known per se for holding the buffer 1 to the frame 2 when the buffer 1 is in its upright position However, the articulation of the buffer 1 to the frame 2 may be of the type allowing the removal of the buffer 1 of this frame in the upright position of the buffer 1.

Le dispositif de l'invention permet d'obturer de manière quasiment hermétique l'ouverture débouchante d'un tampon à l'aide d'un bouchon imperdable et qui peut s'effacer lors de l'introduction d'une clé pour manipuler le verrou de sa position de verrouillage à sa position de déverrouillage du cadre de support en utilisant un verrou d'une structure extrêmement simple. En outre, une fois le tampon déverrouillé de son cadre de support, la clé de déverrouillage est retenue prisonnière au tampon pour permettre à ce dernier d'être manipulé directement par la clé sans que cette dernière puisse se détacher accidentellement du tampon. Enfin, une fois le tampon complètement désengagé du cadre, la clé est imperdable du fait qu'elle demeure prisonnière du tampon.The device of the invention makes it possible to seal, in a virtually hermetic manner, the opening opening of a buffer with the aid of a cap which can be removed and which can be erased when a key is inserted to manipulate the latch. from its locking position to its unlocking position of the support frame using a latch of extremely simple structure. In addition, once the unlocked pad of its support frame, the unlock key is held captive pad to allow the latter to be manipulated directly by the key without the latter can be detached accidentally buffer. Finally, once the buffer completely disengaged from the frame, the key is captive because it remains trapped in the buffer.
