Definitions
- the present invention relates to a backup tool specifically for actuating a device for securing emergency access to a public infrastructure.
- the invention applies in particular to infrastructure such as underground railway stations and galleries, including metro, but can be adapted to any type of site and configuration.
- Such stations which are frequented by a large number of passengers, must have a high level of security.
- rescue teams such as fire brigade teams, must be able to reach strategic areas of the stations very quickly from the outside, that is to say generally from the surface. It is therefore common to provide that these rescue teams do not use public access stations, but specific emergency access.
- these emergency accesses are closed by openings, such as vertical doors or horizontal hatches, immobilized with respect to the wall or floor walls. delimiting the emergency accesses, by a bolt secured to the opening. To open the access, it is necessary to release the opening by releasing sufficiently the bolt vis-à-vis the wall or floor walls. In practice, this action on the bolt must be commanded from outside the access by the rescue teams, while being prohibited to unauthorized persons, in particular to malicious people who seek to fraudulently enter the stations, often for vandalism purposes. Under these conditions, it is known to arrange in the wall or floor wall which extends opposite the bolt a metal pusher finger intended to abut against the bolt to disengage it.
- This pusher finger is fixedly attached to one end of a movable plate, the opposite end fixedly bears a maneuvering square, that is to say a metal stud of square cross section, accessible from the outside, in particular in a recess in the wall or ceiling wall.
- a maneuvering square that is to say a metal stud of square cross section, accessible from the outside, in particular in a recess in the wall or ceiling wall.
- the rescue teams then use a removable bar for driving the plate, this bar delimiting an end imprint, complementary to the maneuvering square, so that when the fingerprint and the maneuvering square are in contact with each other. the other, the rotational drive of the bar causes the platinum to rotate around its end bearing the operating square.
- the pusher finger then describes a circular path, centered on the maneuvering square, until it comes to rest against and release the bolt to release the opening and thus open the emergency access. It will be understood that this plate makes it possible to secure the emergency access, in the sense that only persons having the drive imprint of the square are able
- the object of the present invention is to provide rescue teams, such as fire brigade teams, with an improved rescue tool for very quickly reaching strategic areas of a public infrastructure from outside.
- the subject of the invention is an emergency tool, as defined in claim 1.
- this tool integrates the actuation key of the safety device, that is to say a key specifically adapted to be introduced into and rotate the lock cylinder belonging to this device.
- a rescue tool such as an ax
- an actuating instrument of the safety device such as the square-shaped bar mentioned above.
- Rescue teams carry less material with them and are quicker when they intervene.
- the barrel of the device is advantageously chosen from the so-called high security barrels, that is to say of which barrels certified unclogable. In this way, it is extremely difficult for malicious people to rotate this barrel with tools of such as hooks, while the authorized persons, including rescue teams such as firefighting teams, have the key to this barrel.
- the barrel of the safety device is provided interchangeably, typically during a maintenance intervention, in order to regularly change the internal profile of this barrel, intended to cooperate with a corresponding specific key, so as to limit the risk that after a certain time, keys obtained fraudulently from authorized persons are used in a malicious way.
- the operation of the safety device is based on the cam rotated by the barrel.
- This cam combines reliability and efficiency, in the sense that it is advantageously made of a metal, such as brass, ensuring a long life without problems of deformation and / or seizure.
- this cam makes it possible to urge the thrust piece of the bolt with a force in a rectilinear direction, which is particularly effective for moving the bolt, without the user having to develop a significant torque when it drives the cylinder in rotation by the associated key.
- a single operator is sufficient to release the bolt to release the opening and thus open the emergency access.
- the fact of urging the thrust piece in a rectilinear translational movement offers the possibility of oversize this thrust piece in a plane perpendicular to the direction of translation, without impairing the reliability of the thrust action of the bolt.
- this thrust piece is not strictly centered in direct view of the bolt to push, the bolt is effectively constrained by at least a longitudinal portion of the thrust piece, so that the device according to the invention can be implanted vis-à-vis the bolt to push without a fine positioning is needed on site.
- the mechanism is adaptable to any type of configuration and adapts dimensionally to all possible constraints.
- the use of the barrel is advantageously associated with a principle of organization chart thus making it possible to provide a key firefighters' general password, while lower-level keys are provided to other infrastructure stakeholders, thus guaranteeing the full right of access to these stakeholders while allowing firefighters to intervene.
- a device 1 intended to secure an emergency access 2.
- this access 2 is in the form of an opening defined in a floor masonry 3.
- This opening connects a vertical shaft 4, which leads down to a public infrastructure, such as a subway station or a tunnel, outside 5.
- Well 4 is intended to be used by rescue teams, such as firefighter crews, who have access from outside 5 inside the metro station, when an emergency response, for example following an accident or a fire in the station.
- this access is not normally used by the public.
- the access 2 is closed by a horizontal trapdoor 6.

- the hatch 6 is held in its closed position by a lock 8 carried by the door on the side of the well 4 and including a movable bolt 9.
- this bolt is deployed relative to the rest of the lock 8 so as to be engaged with a striker 10 secured to the floor masonry 3.
- the bolt and the striker cooperate to prevent the articulation of the door and thus keep the latter in its closed position.
- the lock 8 is advantageously provided with an actuating pallet 11, commonly called “anti-panic pallet”. Indeed, this pallet is arranged on the side of the hatch 6 facing the well 4, so as to be actuated by a user arriving to the hatch from inside the station or tunnel.
- actuating pallet 11 commonly called "anti-panic pallet”.
- this pallet is arranged on the side of the hatch 6 facing the well 4, so as to be actuated by a user arriving to the hatch from inside the station or tunnel.
- a traveler who attempts to exit the station by the well 4 from the station is able to quickly and easily actuate the pallet 11 to cause the retraction of the bolt 9 inside the lock. 8, which releases the bolt vis-à-vis the keeper 10 and allows the opening of the trap according to the arrow 7.
- the device 1 is adapted to control the retraction of the bolt 9 in the lock 8 from the outside 5.
- the device 1 is used by rescue teams located outside and must open the hatch 6 to go through the emergency access 2.
- the device 1 comprises a rigid frame 20 of elongated overall shape.
- This frame includes an elongated flat base 21 and an elongated flat plate 22, parallel to each other and firmly fixed to one another, with the interposition of two spacers 23 and 24 respectively located at the longitudinal ends of the base and platinum.
- the base 21, the plate 22 and the shims 23 and 24 are assembled to each other by screws or similar fastening means, not shown in the figures, being noted that the receiving holes of these screws are as for them clearly visible to the figure 3 .
- the frame 20 also comprises a front plate 25 which extends in a plane perpendicular to the base 21 and the plate 22, being for example fixedly connected to the end wedge 24
- the frame 20 is fixedly secured to the floor masonry 3, inside a niche 12 delimited by this masonry.
- This niche 12 communicates with both the outside 5 and the well 4, so that the frame 20 is implanted in this niche so that its plate 25 extends in the extension of one of the walls delimiting the well 4, while that the end of the frame 20 opposite the plate 25 is located opposite the outlet on the outside 5 of the recess 12.
- the fixing of the frame 20 to the floor masonry 3 is carried out by any appropriate means, either by direct anchoring of at least one of the components of the frame in this masonry, or with the interposition of a mechanical fixing bracket, permanently sealed in masonry.
- the device 1 comprises a thrust piece 30 in the form of a metal strip extending parallel to the overall plane of the plate 25. As described in detail below, this piece 30 extends, in use, along a side 25A of the plate 25, movably between retracted and extended extreme positions, which are respectively shown at Figures 4 and 5 and in which the part 30 is respectively set back and beyond the face 25B of the plate 25, facing the well 4, relative to the rest of the frame 20.
- the side 25A of the plate 25 is arranged relative to the bolt 9, so that the thrust member 30 is located opposite the bolt in the direction of movement of this part between its retracted and deployed positions. In this way, it is understood that when the piece 30 moves from its retracted position to its extended position, it can bear against the bolt 9 so as to retract it into the lock 8 and thus free it from the striker 10 to release the hatch 6.
- the device 1 comprises a mechanism 40 for maneuvering the thrust piece 30 between its retracted and deployed positions.
- This mechanism comprises several constituents movably supported by the frame 20, as detailed below.
- the mechanism 40 thus comprises a lock cylinder 42 having the overall shape of a cylinder, adapted to receive a key 44 ( Figures 6 and 7 ) specific to the barrel. More specifically, the barrel 42 internally defines a slot 46 for introducing the key 44 into an internal volume of the barrel, which is not visible in the figures, in which the internal mechanical components of this barrel and the key 44 cooperate by contact to allow the barrel to rotate. driving rotation of the barrel on itself, that is to say around an axis XX which corresponds to the longitudinal central axis of the barrel. To this end, the key 44 has a matched profile to the aforementioned internal constituents of the barrel, so that the use of a key that has a different profile would not rotate the barrel. In practice, the barrel 42 is selected from barrels called "high security", that is to say barrels extremely difficult to crocheteriously fraudulent.
- the slot 46 opens on the outside of the barrel facing this outlet.
- the barrel 42 is located relative to the frame at the end of the latter opposite the plate 25.
- the barrel 42 is supported by a plate 26 covering the plate 22, being noted that this plate 26 is omitted on the Figures 4 and 5 for reasons of visibility.
- the barrel 42 is secured to a protruding key 48 which extends in length in a diametrical direction to the barrel.
- This key 48 is received in a complementary recess 50 delimited in the central region of a cam 52 centered on the X-X axis. In this way, when the barrel 42 is rotated about the X-X axis in either of two possible directions, the cam 52 is driven in an identical rotational movement.
- the cam 52 has, in cross section, a peripheral profile of elliptical shape, centered on the axis XX, as clearly visible on the Figures 4 and 5 .
- this elliptical profile is adapted to cooperate with the circular profile of a roller 58 assembled, freely rotatable about its central axis ZZ parallel to the axis XX, to a plate 60 which extends perpendicularly to the axis ZZ.
- This plate 60 is fixedly secured, by screws not shown, at a longitudinal end of an elongate rigid slideway 62 which, at its opposite bent end, is fixedly secured to the thrust piece 30, by screws not shown.
- the wafer 60, the slideway 62 and the thrust piece 30 thus form a unitary unit, displaceable in translation relative to the frame 20 in a rectilinear direction T perpendicular to the axes XX and ZZ.
- the slide 62 rests in direct contact with the plate 22, advantageously with the interposition of a coating or a plate improving the sliding contact between the slide and the plate, in particular a coating or plate made of brass or Teflon (trademark).
- the frame 20 is advantageously equipped with guide rails 27, laterally bordering the running portion of the slide. In the embodiment considered in the figures, these rails 27 are formed by the superposition of adequately shaped plates fixedly interposed between the plate 22 and the cover plate 26.
- the drive in translation of the thrust member assembly 30 / slide 62 / plate 60 is controlled by the cam 52. Indeed, when this cam is rotated about the axis XX over a quarter of a turn, so to move from his position to the figure 4 to his position of the figure 5 , the elliptical contour of the cam is applied against the circular contour of the roller 58, which then rotates about itself about the axis ZZ, while being generally driven in the direction T, so as to move away from the axis XX. In this way, the roller 58 drives in translation the workpiece assembly 30 / slide 62 / wafer 60 in the direction T.
- the mechanism 40 further comprises a spring 64 which extends in length in the direction of translation T, being interposed between, on the one hand, the wedge 24 and, on the other hand, a stop piece 66 integral with the slide 62.
- the spring 64 and the abutment piece 66 are indicated in dotted lines on the Figures 4 and 5 .
- this piece 66 extends from the face of the slide 62 in sliding contact with the plate 22. To do this, this piece 66 extends through an opening 28 passing through apart from the platinum.
- the size of this opening 28, in the translation direction T is sufficiently large to allow the translation of the stop piece 66, together with the slideway 62, without this stop piece coming into contact with the end edges of the stop. the opening. Thanks to this arrangement, the spring 64 is housed, in a protected manner, between the base 21 and the plate 22.
- a rescue team including a fire brigade team
- the firefighters operate the device 1 in order to release the hatch 6.
- the firefighters operate the device 1 in order to release the hatch 6.
- This ax includes an elongated handle 72, a longitudinal end of which is provided with an ax blade 74.
- the handle 72 delimits, in its running portion, an inner housing 76 intended to receive the key 44 specifically adapted to the barrel 42.
- Key 44 is assembled at tilting at the handle 72, about an axis 78 perpendicular to the longitudinal direction of the handle.
- This key 44 can thus be tilted between a retracted position, represented in FIG. figure 6 wherein the key extends in length in the longitudinal direction of the handle, being concealed in the housing 76, and an extended position, shown in FIG. figure 7 , in which the key extends outside the housing 76, perpendicularly to the handle 72.
- the firefighter tilts the key 44 of its ax 70, from its retracted position of the figure 6 to his deployed position of the figure 7 , as indicated by the arrow 80.
- locking means are provided on the handle 72, so as to maintain the key 44 in one and / or the other of its retracted and deployed positions, so that the fireman acts manually on these locking means to deploy the key 44.
- the firefighter While the key 44 is deployed relative to the handle 72, the firefighter manipulates his ax 70, so as to introduce the key 44 into the barrel 42, via its slot 46, passing this key through the outlet of the niche 12 on the outside 5, as indicated by the arrow 82 at the figure 1 .
- the firefighter drives the barrel 42 in rotation about itself about the axis XX and, thereby, the cam 52.
- the rotation of the cam causes the rectilinear translation of the thrust piece 30, via the roller 58, the wafer 60 and the slide 62.
- the thrust piece 30 then acts in the direction of translation T on the bolt 9, as indicated by the arrow 88 to the figure 5 , to retract it inside its lock 8 and thus release it from the striker 10.
- the firefighter can then open the hatch 6 and thus release the emergency access 2.
- the spring 64 During the drive in translation of the slide 62 to press the piece 30 against the bolt 9, the spring 64 is compressed, but this spring does not create a significant resistance for the firefighter, the resistance of this spring being low, typically of the order of 5 daN.
- the spring 64 recalls the slide in its initial position of the figure 4 , which, on the one hand, by rolling support of the roller 58 against the cam 52, substantially reposition the barrel 42 in its initial position and, on the other hand, recalls the thrust piece 30 away from the bolt 9. In this way, when the emergency intervention ends and the hatch 6 is closed, the device 1 does not require any manipulation to be operated again during the next emergency intervention.
- the team of firefighters quickly and easily opens the emergency access 2.
- the actuation of the device 1 requires only one operator, whose actions can be performed in an extremely short time.
- the fact that the cam 52 allows to be rotated indifferently in the two possible directions of rotation around the axis X-X facilitates the intervention of the firefighter.
- the cam 52 can even make one or more half-turns on itself without damaging the mechanism 40.
- the components of the frame 20 and the mechanism 40, as well as the thrust piece 30 are made of resistant metals, which make the device 1 particularly reliable over time.
- the metallic nature of the frame 20, the thrust member 30 and the mechanism 40 makes the device 1 resistant to attempted break-ins and, more generally, vandalism.
- the latter is advantageously surrounded by a rigid tube 90 carried by a cover 92 secured firmly to the cover plate 26, being noted that this cache is omitted on the Figures 4 and 5 for reasons of visibility.
- the protective tube 90 is assembled to the cover 92 in an idle manner, that is to say that it can freely rotate on itself about the axis XX, limiting the possibility of tearing or damage of the barrel 42 using a pair of pliers.

Abstract
Description
La présente invention concerne un outil de secours spécifiquement destiné à l'actionnement d'un dispositif de mise en sécurité d'un accès de secours à une infrastructure publique.The present invention relates to a backup tool specifically for actuating a device for securing emergency access to a public infrastructure.
Un exemple d'un tel outil de secours est fourni par
L'invention s'applique en particulier à des infrastructures telles que des stations et des galeries souterraines de transport ferroviaire, notamment de métro, mais peut être adaptée à tout type de site et de configuration.The invention applies in particular to infrastructure such as underground railway stations and galleries, including metro, but can be adapted to any type of site and configuration.
De telles stations, qui sont fréquentées en service par un grand nombre de voyageurs, doivent présenter un haut niveau de sécurité. En particulier, des équipes de secours, telles que des équipes de sapeurs pompiers, doivent pouvoir atteindre très rapidement des zones stratégiques des stations depuis l'extérieur, c'est-à-dire généralement depuis la surface. Il est donc courant de prévoir que ces équipes de secours n'utilisent pas les accès publics des stations, mais des accès de secours spécifiques.Such stations, which are frequented by a large number of passengers, must have a high level of security. In particular, rescue teams, such as fire brigade teams, must be able to reach strategic areas of the stations very quickly from the outside, that is to say generally from the surface. It is therefore common to provide that these rescue teams do not use public access stations, but specific emergency access.
En dehors d'une intervention de secours, c'est-à-dire en temps normal, ces accès de secours sont fermés par des ouvrants, tels que des portes verticales ou des trappes horizontales, immobilisés par rapport aux parois de mur ou de sol délimitant les accès de secours, par un pêne solidaire de l'ouvrant. Pour ouvrir l'accès, il est nécessaire de libérer l'ouvrant en dégageant suffisamment le pêne vis-à-vis des parois de mur ou de sol. En pratique, cette action sur le pêne doit être commandée depuis l'extérieur de l'accès par les équipes de secours, tout en étant interdite à des personnes non habilitées, en particulier à des personnes malveillantes qui cherchent à pénétrer frauduleusement dans les stations, souvent à des fins de vandalisme. Dans ces conditions, il est connu d'agencer dans la paroi de mur ou de sol qui s'étend en regard du pêne un doigt pousseur métallique destiné à venir s'appuyer contre le pêne pour le dégager. Ce doigt pousseur est porté fixement à une extrémité d'une platine mobile dont l'extrémité opposée porte fixement un carré de manoeuvre, c'est-à-dire un téton métallique de section transversale carrée, accessible depuis l'extérieur, notamment dans une niche ménagée dans la paroi de mur ou de plafond. Les équipes de secours utilisent alors une barre amovible d'entraînement de la platine, cette barre délimitant une empreinte d'extrémité, complémentaire du carré de manoeuvre, de sorte que lorsque cette empreinte et le carré de manoeuvre sont en prise l'un dans l'autre, l'entraînement en rotation de la barre provoque la mise en rotation de la platine autour de son extrémité portant le carré de manoeuvre. Le doigt pousseur décrit alors une trajectoire circulaire, centrée sur le carré de manoeuvre, jusqu'à venir s'appuyer contre et dégager le pêne pour libérer l'ouvrant et ainsi ouvrir l'accès de secours. On comprend que cette platine permet de mettre en sécurité l'accès de secours, dans le sens où seules les personnes disposant de l'empreinte d'entraînement du carré de manoeuvre sont à même d'ouvrir l'accès.Apart from an emergency intervention, that is to say in normal times, these emergency accesses are closed by openings, such as vertical doors or horizontal hatches, immobilized with respect to the wall or floor walls. delimiting the emergency accesses, by a bolt secured to the opening. To open the access, it is necessary to release the opening by releasing sufficiently the bolt vis-à-vis the wall or floor walls. In practice, this action on the bolt must be commanded from outside the access by the rescue teams, while being prohibited to unauthorized persons, in particular to malicious people who seek to fraudulently enter the stations, often for vandalism purposes. Under these conditions, it is known to arrange in the wall or floor wall which extends opposite the bolt a metal pusher finger intended to abut against the bolt to disengage it. This pusher finger is fixedly attached to one end of a movable plate, the opposite end fixedly bears a maneuvering square, that is to say a metal stud of square cross section, accessible from the outside, in particular in a recess in the wall or ceiling wall. The rescue teams then use a removable bar for driving the plate, this bar delimiting an end imprint, complementary to the maneuvering square, so that when the fingerprint and the maneuvering square are in contact with each other. the other, the rotational drive of the bar causes the platinum to rotate around its end bearing the operating square. The pusher finger then describes a circular path, centered on the maneuvering square, until it comes to rest against and release the bolt to release the opening and thus open the emergency access. It will be understood that this plate makes it possible to secure the emergency access, in the sense that only persons having the drive imprint of the square are able to open the access.
Toutefois, la forme rudimentaire de ce carré de manoeuvre rend l'empreinte d'entraînement correspondante facile à copier, de sorte que des personnes malveillantes se procurent facilement l'outillage suffisant pour actionner la platine. Pour résoudre ce problème, on a proposé d'utiliser un ressort de compression présentant une raideur élevée, typiquement de 80 DaN. Ce ressort de compression est interposé entre la platine et un châssis de support de cette platine, de sorte que, pour entraîner en rotation la platine par rapport au châssis, il est nécessaire de développer un effort significatif. En pratique, trois personnes sont alors nécessaires : deux personnes coopèrent pour appliquer un couple suffisant sur la barre d'actionnement du carré de manoeuvre afin de vaincre la résistance du ressort, tandis qu'une troisième personne libère l'ouvrant une fois le pêne suffisamment déplacé par le doigt pousseur. Les équipes de secours connaissent les manipulations nécessaires à l'ouverture de l'accès de secours, mais ce dispositif ne dissuade qu'imparfaitement les personnes malveillantes. Cependant, on comprend que ces manipulations sont fastidieuses pour les équipes de secours, en particulier lorsque la platine est intégrée à une paroi de mur car le carré de manoeuvre n'est alors accessible que suivant une direction horizontale, ce qui induit des contraintes ergonomiques pour les deux personnes nécessaires pour vaincre la résistance du ressort, ces deux personnes ayant tendance à se gêner mutuellement. En outre, la résistance générée par le ressort impose d'agencer le châssis de support de la platine dans un paroi de mur ou de plafond particulièrement résistante, faute de quoi les fortes contraintes appliquées lors de l'entraînement en rotation de la platine risquent d'endommager cette paroi.However, the rudimentary form of this square maneuver makes the corresponding training fingerprint easy to copy, so that malicious people easily get enough tools to operate the platen. To solve this problem, it has been proposed to use a compression spring having a high stiffness, typically 80 DaN. This compression spring is interposed between the plate and a support frame of this plate, so that, in order to rotate the plate relative to the chassis, it is necessary to develop a significant effort. In practice, three people are needed: two people cooperate to apply sufficient torque on the actuating bar of the square to overcome the resistance of the spring, while a third person releases the opening once the bolt enough moved by the pusher finger. Rescue teams know the steps necessary to open the emergency access, but this device only dissuades imperfectly the malicious people. However, it is understood that these manipulations are tedious for the rescue teams, especially when the plate is integrated into a wall wall because the square maneuver is then accessible that in a horizontal direction, which induces ergonomic constraints for both people necessary to overcome the resistance of the spring, these two people tend to interfere with each other. In addition, the resistance generated by the spring requires to arrange the support frame of the plate in a particularly strong wall or ceiling wall, otherwise the high stresses applied during the rotational drive of the plate may 'damage this wall.
Le but de la présente invention est de fournir à des équipes de secours, telles que des équipes de sapeurs pompiers, un outil de secours amélioré pour atteindre très rapidement des zones stratégiques d'une infrastructure publique depuis l'extérieur.The object of the present invention is to provide rescue teams, such as fire brigade teams, with an improved rescue tool for very quickly reaching strategic areas of a public infrastructure from outside.
A cet effet, l'invention a pour objet un outil de secours, tel que défini à la revendication 1.For this purpose, the subject of the invention is an emergency tool, as defined in
Selon l'invention, cet outil intègre la clé d'actionnement du dispositif de mise en sécurité, c'est-à-dire une clé spécifiquement adaptée pour être introduite dans et entraîner en rotation le barillet de serrure appartenant à ce dispositif. Ainsi, les équipes de secours n'ont pas à disposer, en plus d'un outil de secours tel qu'une hache, d'un instrument d'actionnement du dispositif de mise en sécurité, tel que la barre à empreinte carrée évoquée plus haut, puisque leur hache de secours est également utilisable pour actionner le dispositif de mise en sécurité. Les équipes de secours transportent ainsi avec elles moins de matériel et sont plus rapides lors de leur intervention.According to the invention, this tool integrates the actuation key of the safety device, that is to say a key specifically adapted to be introduced into and rotate the lock cylinder belonging to this device. Thus, rescue teams do not have to have, in addition to a rescue tool such as an ax, an actuating instrument of the safety device, such as the square-shaped bar mentioned above. high, since their emergency ax is also usable to operate the safety device. Rescue teams carry less material with them and are quicker when they intervene.
Une des idées sous-jacente du dispositif de mise en sécurité est de dissuader les personnes malveillantes non pas en prévoyant une résistance mécanique significative à vaincre pour actionner le dispositif, mais en restreignant la capacité d'actionnement du dispositif grâce au barillet de serrure, choisi pour ne pouvoir être sollicité que par la clé spécifiquement adaptée à ce barillet. Le barillet du dispositif est avantageusement choisi parmi les barillets dits de haute sécurité, c'est-à-dire dont des barillets certifiés incrochetables. De cette façon, il est extrêmement difficile à des personnes malveillantes d'entraîner en rotation ce barillet avec des outils de crochetage, tels que des crochets, tandis que les personnes habilitées, notamment les équipes de secours telles que les équipes de sapeurs pompiers, disposent de la clé propre à ce barillet. Avantageusement, le barillet du dispositif de mise en sécurité est prévu interchangeable, typiquement lors d'une intervention de maintenance, afin de changer régulièrement le profil intérieur de ce barillet, destiné à coopérer avec une clé spécifique correspondante, de façon à limiter le risque que, au bout d'un certain temps, des clés obtenues frauduleusement auprès de personnes habilitées ne soient utilisées de façon malveillante.One of the underlying ideas of the safety device is to deter malicious people not by providing a significant mechanical strength to overcome to operate the device, but by restricting the ability to operate the device with the lock cylinder, chosen to be able to be solicited only by the key specifically adapted to this barrel. The barrel of the device is advantageously chosen from the so-called high security barrels, that is to say of which barrels certified unclogable. In this way, it is extremely difficult for malicious people to rotate this barrel with tools of such as hooks, while the authorized persons, including rescue teams such as firefighting teams, have the key to this barrel. Advantageously, the barrel of the safety device is provided interchangeably, typically during a maintenance intervention, in order to regularly change the internal profile of this barrel, intended to cooperate with a corresponding specific key, so as to limit the risk that after a certain time, keys obtained fraudulently from authorized persons are used in a malicious way.
En outre, le fonctionnement du dispositif de mise en sécurité repose sur la came entraînée en rotation par le barillet. Cette came associe fiabilité et efficacité, dans le sens où elle est avantageusement constituée d'un métal, tel que le laiton, assurant une grande longévité sans problème de déformation et/ou de grippage. De plus, cette came permet de solliciter la pièce de poussée du pêne avec un effort selon une direction rectiligne, ce qui s'avère particulièrement efficace pour déplacer le pêne, sans pour autant que l'utilisateur n'ait à développer un couple important lorsqu'il entraîne le barillet en rotation par la clé associée. Ainsi, un seul opérateur est suffisant pour dégager le pêne afin de libérer l'ouvrant et ainsi ouvrir l'accès de secours.In addition, the operation of the safety device is based on the cam rotated by the barrel. This cam combines reliability and efficiency, in the sense that it is advantageously made of a metal, such as brass, ensuring a long life without problems of deformation and / or seizure. In addition, this cam makes it possible to urge the thrust piece of the bolt with a force in a rectilinear direction, which is particularly effective for moving the bolt, without the user having to develop a significant torque when it drives the cylinder in rotation by the associated key. Thus, a single operator is sufficient to release the bolt to release the opening and thus open the emergency access.
Par ailleurs, le fait de solliciter la pièce de poussée suivant un mouvement de translation rectiligne offre la possibilité de surdimensionner cette pièce de poussée dans un plan perpendiculaire à la direction de translation, sans nuire à la fiabilité de l'action de poussée du pêne. De la sorte, même si cette pièce de poussée n'est pas rigoureusement centrée en regard direct du pêne à pousser, ce pêne est efficacement contraint par au moins une partie longitudinale de la pièce de poussée, si bien que le dispositif selon l'invention peut être implanté vis-à-vis du pêne à pousser sans qu'un positionnement fin ne soit nécessaire sur site.Furthermore, the fact of urging the thrust piece in a rectilinear translational movement offers the possibility of oversize this thrust piece in a plane perpendicular to the direction of translation, without impairing the reliability of the thrust action of the bolt. In this way, even if this thrust piece is not strictly centered in direct view of the bolt to push, the bolt is effectively constrained by at least a longitudinal portion of the thrust piece, so that the device according to the invention can be implanted vis-à-vis the bolt to push without a fine positioning is needed on site.
Bien entendu, le mécanisme est adaptable à tout type de configuration et s'adapte de manière dimensionnelle à toutes les contraintes envisageables. De plus, l'utilisation du barillet est avantageusement associée à un principe d'organigramme permettant ainsi de fournir une clef de passe général aux sapeurs-pompiers, tandis que des clefs de niveau inférieur sont fournies aux autres intervenants de l'infrastructure, garantissant ainsi l'intégralité du droit d'accès à ces intervenants tout en autorisant l'intervention par les sapeurs-pompiers.Of course, the mechanism is adaptable to any type of configuration and adapts dimensionally to all possible constraints. In addition, the use of the barrel is advantageously associated with a principle of organization chart thus making it possible to provide a key firefighters' general password, while lower-level keys are provided to other infrastructure stakeholders, thus guaranteeing the full right of access to these stakeholders while allowing firefighters to intervene.
Une caractéristique avantageuse de l'outil de secours est définie à la revendication 2An advantageous feature of the rescue tool is defined in

Sur les
Afin de réserver l'accès 2 aux équipes de secours, cet accès n'est pas utilisé normalement par le public. A cette fin, l'accès 2 est obturé par une trappe horizontale 6. Sur l'un de ses côtés, cette trappe est articulée, par tout moyen approprié, par rapport à la maçonnerie de sol 3, entre une position de fermeture, représentée à la
La trappe 6 est maintenue dans sa position de fermeture par une serrure 8 portée par la trappe du côté du puits 4 et incluant un pêne mobile 9. Au repos, comme représenté sur la
La serrure 8 est avantageusement munie d'une palette d'actionnement 11, couramment appelée « palette anti-panique ». En effet, cette palette est agencée du côté de la trappe 6 tourné vers le puits 4, de manière à pouvoir être actionnée par un utilisateur arrivant jusqu'à la trappe depuis l'intérieur de la station ou du tunnel. Ainsi, en cas d'incident, un voyageur qui tenterait de sortir en urgence de la station par le puits 4 est en mesure d'actionner rapidement et facilement la palette 11 pour provoquer l'escamotage du pêne 9 à l'intérieur de la serrure 8, ce qui dégage le pêne vis-à-vis de la gâche 10 et permet l'ouverture de la trappe selon la flèche 7.The
Indépendamment de la possibilité d'escamoter le pêne 9 en actionnant la serrure 8 par la palette anti-panique 11, le dispositif 1 est adapté pour commander l'escamotage du pêne 9 dans la serrure 8 depuis l'extérieur 5. Typiquement, le dispositif 1 est utilisé par des équipes de secours situées à l'extérieur et qui doivent ouvrir la trappe 6 pour passer par l'accès de secours 2.Regardless of the possibility of retracting the
A cet effet, comme indiqué très schématiquement sur la
A l'une de ses extrémités longitudinales, le châssis 20 comporte également une plaque frontale 25 qui s'étend dans un plan perpendiculaire à l'embase 21 et à la platine 22, en étant par exemple assemblée fixement à la cale d'extrémité 24. Dans la configuration implantée du dispositif 1, c'est-à-dire lorsque ce dispositif est agencé vis-à-vis de l'accès de secours 2 comme sur la
En pratique, la fixation du châssis 20 à la maçonnerie de sol 3 est réalisée par tout moyen approprié, soit par un ancrage direct d'au moins un des composants du châssis dans cette maçonnerie, soit avec interposition d'une console de fixation mécanique, scellée à demeure dans la maçonnerie.In practice, the fixing of the
Afin d'agir par appui pressant contre le pêne 9, le dispositif 1 comporte une pièce de poussée 30 sous forme d'une barrette métallique s'étendant parallèlement au plan global de la plaque 25. Comme décrit en détail ci-après, cette pièce 30 s'étend, en service, le long d'un côté 25A de la plaque 25, de manière mobile entre des positions extrêmes escamotée et déployée, qui sont respectivement représentées aux
A cet effet, le dispositif 1 comporte un mécanisme 40 de manoeuvre de la pièce de poussée 30 entre ses positions escamotée et déployée. Ce mécanisme comporte plusieurs constituants supportés de manière mobile par le châssis 20, comme détaillé ci-dessous.For this purpose, the
Le mécanisme 40 comporte ainsi un barillet de serrure 42 présentant la forme globale d'un cylindre, adapté pour recevoir une clé 44 (
Pour permettre d'amener facilement la clé 44 jusque dans le barillet 42 en la passant par le débouché de la niche 12 sur l'extérieur 5, la fente 46 débouche sur l'extérieur du barillet en regard de ce débouché. Ainsi, le barillet 42 est situé par rapport au châssis au niveau de l'extrémité de ce dernier opposée à la plaque 25. En pratique, le barillet 42 est supporté par une plaque 26 de couverture de la platine 22, étant remarqué que cette plaque 26 est omise sur les
A son extrémité opposée à la fente 46, le barillet 42 est solidaire d'une clavette saillante 48 qui s'étend en longueur suivant une direction diamétrale au barillet. Cette clavette 48 est reçue dans un évidement complémentaire 50 délimité dans la région centrale d'une came 52 centrée sur l'axe X-X. De cette façon, lorsque le barillet 42 est entraîné en rotation autour de l'axe X-X dans l'un ou l'autre des deux sens possibles, la came 52 est entraînée dans un mouvement de rotation identique.At its opposite end to the
La came 52 présente, en coupe transversale, un profil périphérique de forme elliptique, centré sur l'axe X-X, comme bien visible sur les
La plaquette 60, la glissière 62 et la pièce de poussée 30 forment ainsi un ensemble d'un seul tenant, déplaçable en translation par rapport au châssis 20 suivant une direction rectiligne T perpendiculaire aux axes X-X et Z-Z. A cet effet, la glissière 62 repose en contact direct sur la platine 22, avantageusement avec interposition d'un revêtement ou d'une plaque améliorant le contact glissant entre la glissière et la platine, notamment un revêtement ou une plaque en laiton ou en téflon (marque déposée). Pour guider efficacement la glissière 62 suivant sa direction de translation, le châssis 20 est avantageusement équipé de rails de guidage 27, bordant latéralement la partie courante de glissière. Dans l'exemple de réalisation considéré aux figures, ces rails 27 sont réalisés par la superposition de plaques conformées de manière adéquate et interposées fixement entre la platine 22 et la plaque de couverture 26.The
L'entraînement en translation de l'ensemble pièce de poussée 30/glissière 62/plaquette 60 est commandé par la came 52. En effet, lorsque cette came est entraînée en rotation autour de l'axe X-X sur un quart de tour, de manière à passer de sa position de la
Le mécanisme 40 comprend en outre un ressort 64 qui s'étend en longueur suivant la direction de translation T, en étant interposé entre, d'une part, la cale 24 et, d'autre part, une pièce de butée 66 solidaire de la glissière 62. Le ressort 64 et la pièce de butée 66 sont indiqués en traits pointillés sur les
Le fonctionnement du dispositif 1 va être décrit ci-après, dans le cadre d'un exemple d'une intervention de secours via l'accès 2.The operation of the
Dans ce cas, une équipe de secours, notamment une équipe de sapeurs pompiers, se trouve à l'extérieur 5 de l'accès de secours 2. Pour ouvrir cet accès, les sapeurs pompiers actionnent le dispositif 1 afin de libérer la trappe 6. A cet effet, un des sapeurs pompiers utilise avantageusement la hache 70 représentée aux
En vue d'actionner le dispositif 1, le sapeur pompier bascule la clé 44 de sa hache 70, depuis sa position escamotée de la
Alors que la clé 44 est déployée par rapport au manche 72, le sapeur pompier manipule sa hache 70, de manière à introduire la clé 44 dans le barillet 42, via sa fente 46, en passant cette clé à travers le débouché de la niche 12 sur l'extérieur 5, comme indiqué par la flèche 82 à la
Lors de l'entraînement en translation de la glissière 62 pour appuyer la pièce 30 contre le pêne 9, le ressort 64 est comprimé, sans toutefois que ce ressort ne crée une résistance significative pour le sapeur pompier, la résistance de ce ressort étant faible, typiquement de l'ordre de 5 daN. Lorsque le sapeur pompier dégage la clé 44 du barillet 42, le ressort 64 rappelle la glissière dans sa position initiale de la
Ainsi, grâce au dispositif 1, l'équipe de sapeurs pompiers ouvre rapidement et facilement l'accès de secours 2. L'actionnement du dispositif 1 ne nécessite qu'un seul opérateur, dont les gestes peuvent être réalisés en un temps extrêmement court. Au surplus, le fait que la came 52 autorise d'être mise en rotation indifféremment selon les deux sens de rotation possibles autour de l'axe X-X, facilite l'intervention du sapeur pompier. D'ailleurs, la came 52 peut même faire un ou plusieurs demi-tours sur elle-même sans endommager le mécanisme 40.Thus, thanks to the
En pratique, les constituants du châssis 20 et du mécanisme 40, ainsi que la pièce de poussée 30 sont réalisés en des métaux résistants, qui rendent le dispositif 1 particulièrement fiable dans le temps.In practice, the components of the
En outre, la nature métallique du châssis 20, de la pièce de poussée 30 et du mécanisme 40 rend le dispositif 1 résistant aux tentatives d'effractions et, plus généralement, au vandalisme. A ce titre, pour protéger davantage le barillet 42, ce dernier est avantageusement entouré par un tube rigide 90 porté par un cache 92 solidarisé fermement à la plaque de couverture 26, étant remarqué que ce cache est omis sur les
En outre, le fait d'entraîner la pièce de poussée 30 selon la translation rectiligne T permet de solliciter efficacement le pêne 9 pour l'escamoter dans sa serrure 8. Cette efficacité d'action sur le pêne est insensible au positionnement précis de la pièce de poussée 30, tant qu'au moins une partie longitudinale de celle-ci est située en regard du pêne selon la direction T. Autrement dit, on dispose d'une certaine liberté d'implantation du dispositif 1 dans la niche 12, sans nuire à son efficacité.In addition, the fact of driving the
Divers aménagements et variantes au dispositif 1 et à la hache 70 décrits ci-dessus sont par ailleurs envisageables. A titre d'exemples :
- plutôt que d'être implanté dans la maçonnerie de
sol 3,le dispositif 1 peut être mis en place dans une paroi de mur, notamment une paroi verticale délimitant un accès de secours normalement obturé par une porte ; le dispositif 1 peut même être fixé directement au dormant de l'ouvrant obturant normalement l'accès de secours, sous réserve que ce dormant présente une résistance structurelle suffisante ; - la transmission du mouvement de translation entre la came 52 et la glissière 62 peut être assurée par d'autres pièces de transmission que le galet 58 et la plaquette 60 ; un appui direct entre la came et l'extrémité de la glissière est également envisageable ;
- la hache des
figures 6 n'est qu'un exemple illustratif d'un outil de secours dont le manche est muni de la clé 44 permettant d'actionner le dispositif 1 ; d'autres outils à manche sont envisageables, tel qu'un pied de biche, etc. ; de même, chaque extrémité du manche est avantageusement munie d'un moyen d'action, de sorte que, par exemple, l'extrémité du manche 72 non représentée sur leset 7figures 6 est ainsi munie d'un pied de biche ;et 7 - d'autres aménagements visant à renforcer la résistance au vandalisme du mécanisme 40 sont envisageables ; en particulier, la fente 46 est avantageusement équipée d'une pastille anti-percement, non représentée sur les figures, limitant la possibilité d'introduire des outils de crochetage à l'intérieur du barillet 42 ; et/ou
- de même, la fente 46 peut être recouverte d'un bouchon amovible anti-poussière, pour empêcher l'encrassement du barillet 42.
- rather than being implanted in the
floor masonry 3, thedevice 1 can be put in place in a wall wall, in particular a vertical wall delimiting an emergency access normally closed by a door; thedevice 1 can even be fixed directly to the frame of the opening normally closing the emergency access, provided that this frame has sufficient structural strength; - the transmission of the translation movement between the
cam 52 and theslideway 62 can be provided by other transmission parts than theroller 58 and theplate 60; a direct support between the cam and the end of the slide is also possible; - the ax of
Figures 6 and 7 is only an illustrative example of a rescue tool whose handle is provided with the key 44 for actuating thedevice 1; other tools with handles are possible, such as a crowbar, etc. ; likewise, each end of the handle is advantageously provided with a means of action, so that, for example, the end of thehandle 72 not shown on theFigures 6 and 7 is thus provided with a crowbar; - other arrangements to enhance the vandalism resistance of the
mechanism 40 are conceivable; in particular, theslot 46 is advantageously equipped with an anti-drilling pellet, not shown in the figures, limiting the possibility of introducing hooking tools inside thebarrel 42; and or - likewise, the
slot 46 may be covered with a removable dust-proof cap, to prevent fouling of thebarrel 42.
