Description

L'invention concerne un dispositif pour ouvrir en force des portes, fenêtres et autres ouvrants avec sa commande à distance.The invention relates to a device for opening doors, windows and other openings in force with its remote control.

A ce jour, les sapeurs pompiers, ou tout autre corps de métier pouvant être amené à intervenir d'urgence tel que la police, la gendarmerie, le génie, les groupes d'intervention de type GIGN ou GIPN, rencontrent des difficultés pour pénétrer dans les appartements d'immeubles, les maisons individuelles, les bâtiments industriels et commerciaux dans le cadre d'intervention de secours. En effet, ces difficultés sont le plus souvent liées à la résistance des portes blindées qui peuvent résister entre 15 et 20 minutes à la force d'une masse manipulée par les pompiers, lesquels sont donc parfois épuisés ou moins réactifs et moins efficaces face au danger, particulièrement en cas de feu. A titre d'information, il existe cinq niveaux de référence concernant les portes blindées à simple ou double vantaux. Le chiffre cinq est le niveau le plus élevé de résistance à l'effraction avec une résistance à la déformation à partir de 4 tonnes de poussée. Ce type de porte est ainsi équipé d'une serrure à 6 points, avec des pistons de diamètre de 18 mm en acier trempé et de 40 mm de pénétration dans un châssis en acier trempé de 3 mm d'épaisseur.To date, firefighters, or any other professional body that may be called upon to intervene urgently, such as the police, the gendarmerie, the engineers, the GIGN or GIPN type intervention groups, have difficulties to enter apartment buildings, detached houses, industrial and commercial buildings in the context of emergency intervention. Indeed, these difficulties are most often related to the resistance of armored doors that can withstand between 15 and 20 minutes the force of a mass handled by firefighters, which are sometimes exhausted or less reactive and less effective in the face of danger , especially in case of fire. For your information, there are five reference levels for armored doors with single or double leaves. The number five is the highest level of burglar resistance with a resistance to deformation from 4 tons of thrust. This type of door is equipped with a 6-point lock, with 18 mm diameter hardened steel pistons and 40 mm penetration in a 3 mm thick hardened steel frame.

Il existe déjà des équipements permettant d'enfoncer des portes blindées, appelées « Door Breaker » mais ceux-ci ne conviennent pas aux sapeurs pompiers car ils sont lourds, encombrants, peu manoeuvrables, peu efficaces, longs à mettre en oeuvre et d'utilisation limitée. Or, lors d'une intervention d'urgence, notamment en cas de feu ou de risque d'intoxication, chaque seconde de perdue à ouvrir la porte est un risque supplémentaire d'avoir des dégâts et des victimes, aussi bien du côté des individus à secourir que des pompiers. une autre variante servant d'arriére plan technologique à l'invention est décrite dans le document EP 0271207 There are already equipment to drive armored doors, called "Door Breaker" but they are not suitable for firefighters because they are heavy, bulky, unmanageable, inefficient, long to implement and use limited. However, during an emergency intervention, especially in case of fire or risk of intoxication, every second of lost to open the door is an additional risk of having damage and victims, both on the side of individuals to rescue only firefighters. another variant serving as a technological background to the invention is described in the document EP 0271207

Pour résoudre ces problèmes, l'invention propose de réaliser un dispositif d'ouverture à force d'ouvrants, tels que des portes ou des fenêtres, portatif, avec une force de frappe importante pour une meilleure efficacité, facile d'utilisation et sûr.To solve these problems, the invention proposes to realize a device for opening by force of openings, such as doors or windows, portable, with a large strike force for better efficiency, easy to use and safe.

L'organe de blocage 60 comporte également deux cliquets 62 articulés autour d'axes 65 aménagés dans le tiroir 61. Les cliquets 62 sont placés en oppositions l'un par rapport à l'autre, dos à dos et disposés chacun en regard d'une crémaillères 15 ou 16. Deux ressorts de rappels 64 relient les cliquets au niveau de leurs axes. La plaque 23 présente également deux ergots 24 dressées axialement permettant de maintenir en position les cliquets 62 contre la force de rappel des ressorts de rappels 64.A locking member 60 comprises, in addition to the racks 15 and 16, a slide 61 screwed to the free end 52a of the jack rod 52 and cooperating with the outer sleeve 10. The locking member 60 also comprises two pawls 62 hinged around the axes 65 arranged in the drawer 61. The pawls 62 are placed in oppositions relative to each other, back to back and each arranged opposite a rack 15 or 16. Two springs of reminders 64 connect the ratchets at their axes. The plate 23 also has two pins 24 raised axially to keep the pawls 62 in position against the restoring force of the recoil springs 64.

Une seconde poignée de préhension 28 est également soudées proche de l'extrémité 20a du fourreau interne 20, parallèlement à la première poignée 18.A second handle 28 is also welded close to the end 20a of the inner sleeve 20, parallel to the first handle 18.

Le vérin d'écartement 50 est muni d'une connexion rapide 54 à une bouteille d'air sous pression 70 par l'intermédiaire d'un flexible 55 anti-feu et anti-écrasement, et d'une télécommande à distance 80, et d'une soupape 56. Un premier bouton 26 d'actionnement du vérin 50 est prévu proche de la seconde poignée 28.The spacer cylinder 50 is provided with a quick connection 54 to a pressurized air cylinder 70 via an anti-fire and anti-crushing hose 55, and a remote remote control 80, and of a valve 56. A first button 26 for actuating the jack 50 is provided close to the second handle 28.

Le vérin de poussée 30 est monté coulissant sur le fourreau externe 10 par l'intermédiaire d'une liaison de type queue d'aronde avec la rampe longitudinale 14. Le vérin de poussée 30 peut ainsi se déplacer sur sensiblement toute la longueur du fourreau externe 10. Ce vérin 30 comporte un soufflet 32 étanche par exemple en caoutchouc renforcé, une connexion rapide 34 à la bouteille d'air comprimé 70 par l'intermédiaire d'un flexibles 35 anti-feu et anti-écrasement et de la télécommande à distance 80, une soupape d'échappement 36 et une plaque d'appui rigide 38.The thrust cylinder 30 is slidably mounted on the outer sheath 10 via a dovetail type connection with the longitudinal ramp 14. The thrust cylinder 30 can thus move over substantially the entire length of the outer sheath 10. This jack 30 comprises a bellows 32 tight for example reinforced rubber, a quick connection 34 to the cylinder of compressed air 70 via a flexible 35 anti-fire and anti-crush and remote control 80, an exhaust valve 36 and a rigid support plate 38.

La télécommande à distance 80 comprend des connexions rapides 84 pour les flexibles 55 et 35 partant vers les vérins 30 et 50, et pour un flexible 74 partant vers la bouteille de gaz sous pression 70. Deux boutons 83 et 85 sont prévus pour piloter respectivement le vérin d'écartement 50 et le vérin de poussée 30. Ces boutons sont facilement repérables, même de manière aveugle, par exemple dans la fumée et/ou avec un masque respiratoire sur le visage. A cet effet, le deuxième bouton 83 est plus proéminent que le troisième bouton 85.The remote control 80 comprises quick connections 84 for the hoses 55 and 35 going to the jacks 30 and 50, and for a hose 74 leading to the pressurized gas cylinder 70. Two buttons 83 and 85 are provided for controlling the spacer cylinder 50 and the thrust cylinder 30. These buttons are easily identifiable, even blindly, for example in the smoke and / or with a breathing mask on the face. For this purpose, the second button 83 is more prominent than the third button 85.

Le principe de fonctionnement du dispositif conforme à l'invention est le suivant. Le dispositif, tenu par ses poignée 18 et 28 par l'opérateur, est placé dans n'importe quelle position entre les montants de la porte, par exemple horizontalement, légèrement incliné ou verticalement. Les deux fourreaux sont écartés manuellement afin de placer les coins en titane 12 et 22 entre une partie ouvrante 102 et un châssis latéral 104 de la porte 100.The operating principle of the device according to the invention is as follows. The device, held by its handles 18 and 28 by the operator, is placed in any position between the uprights of the door, for example horizontally, slightly inclined or vertically. The two sleeves are moved apart manually to place the titanium wedges 12 and 22 between an opening portion 102 and a side frame 104 of the door 100.

Le vérin de poussée 30 est manoeuvré le long de la rampe 14 afin de le placer le plus proche possible de la serrure 105 de la porte 100.The thrust cylinder 30 is maneuvered along the ramp 14 to place it as close as possible to the lock 105 of the door 100.

Une fois dans cette position illustrée par la figure 4, l'opérateur appuie sur le premier bouton 26 solidaire du dispositif 1 afin de déclencher l'arrivée de l'air sous pression dans le vérin d'écartement 50. Lors de cette mise en pression lente, le vérin d'écartement 50 pousse sa tige 52 pour écarter le fourreau externe 10 du fourreau interne 20 de quelques mm à quelques centimètres, typiquement entre 50 et 100 mm, ce qui a pour effet de faire pénétrer les coins 12 et 22 plus ou moins profondément dans le châssis 104 de la porte 100. En même temps, les deux cliquets 62 de l'organe de blocage 60 pivotent petit à petit à mesure que les fourreaux s'écartent et que les ergots 24 s'éloignent desdits cliquets 62, puis se mettent en prise avec les crans 17 des deux crémaillères 15 et 16 afin de bloquer le dispositif 1 en position. A partir de ce moment, les fourreaux 10 et 20 ne peuvent plus se rapprocher l'un de l'autre sans purge du vérin d'écartement 50 qui reste donc en permanence sous pression. Le dispositif est alors verrouillé et prêt à être utilisé.Once in this position illustrated by the figure 4 , the operator presses on the first button 26 secured to the device 1 in order to trigger the arrival of pressurized air in the spacer cylinder 50. During this slow pressurization, the spacer cylinder 50 pushes its rod 52 to separate the outer sleeve 10 of the inner sleeve 20 from a few mm to a few centimeters, typically between 50 and 100 mm, which has the effect of making the corners 12 and 22 penetrate more or less deeply into the frame 104 of the door 100. At the same time, the two pawls 62 of the locking member 60 pivot gradually as the sleeves move apart and the lugs 24 move away from said pawls 62, then engage with the catches 17 two racks 15 and 16 to block the device 1 in position. From this moment, the sleeves 10 and 20 can no longer approach one another without purging the spacer cylinder 50 which therefore remains permanently under pressure. The device is then locked and ready to use.

L'opérateur saisi alors la télécommande 70 et se place le plus loin possible tout en ayant de préférence un regard sur la porte 100 et le dispositif 1 afin de contrôler l'état d'avancement de l'opération d'enfoncement. Typiquement, compte tenue de la longueur des flexibles de commande 55 et 35, l'opérateur peut se placer à 5 mètres.The operator then grasps the remote control 70 and places himself as far as possible while preferably having a look on the door 100 and the device 1 to control the progress of the driving operation. Typically, given the length of the control hoses 55 and 35, the operator can be placed at 5 meters.

L'opérateur appuie alors sur le deuxième bouton 83 qui est placé sur la télécommande 80, ce qui a pour effet de piloter le vérin d'écartement 50 qui pousse cette fois-ci par sa platine de fond 51 puisque les cliquets 62 font office de butée pour la tige de vérin 52. Ceci a pour effet de faire pénétrer encore plus profondément les coins 12 et 22 et dans le châssis 104 de la porte 100, en particulier au niveau des points de fermeture. La force de pénétration est typiquement comprise entre 5 et 20 KN, par exemple 13,5 KN, sous une pression d'air de 8 bars et avec une course longitudinale d'environ 95 mm au total.The operator then presses the second button 83 which is placed on the remote control 80, which has the effect of controlling the spacer cylinder 50 which this time pushes by its bottom plate 51 since the pawls 62 serve as stop for the cylinder rod 52. This has the effect of further penetrating the corners 12 and 22 and in the frame 104 of the door 100, in particular at the closing points. The penetration force is typically between 5 and 20 KN, for example 13.5 KN, under an air pressure of 8 bar and with a longitudinal stroke of about 95 mm in total.

Deux cas peuvent alors se présenter. Dans le premier cas, les montants du châssis 104 sont classique et peu résistants, par exemple en bois. Les coins 12 et 22 utilisés pénètrent alors entre la partie ouvrante 102 et le châssis 104, et le vérin d'écartement 50 arrive en course maximale. La poussée du vérin d'écartement 50 et des coins 12 et 22 est alors supérieure à la résistance du châssis 104, ce qui permet de le déformer, en particulier proche de la serrure et/ou des gonds. Dans le second cas, le châssis 104 est très résistant, par exemple muni de cornières en métal épais. Les coins 12 et 22 pénètrent alors entre la partie ouvrante 102 et le châssis 104, et le vérin d'écartement 50 n'est pas en course maximale, il permet de maintenir le dispositif dans sa position pour permettre de faciliter le travail du vérin 30 de poussée à percussion.Two cases can then arise. In the first case, the amounts of the frame 104 are conventional and weak, for example wood. The corners 12 and 22 used then penetrate between the opening portion 102 and the frame 104, and the spacer cylinder 50 arrives in maximum stroke. The thrust of the spacer cylinder 50 and the corners 12 and 22 is then greater than the strength of the frame 104, which allows to deform, in particular close to the lock and / or hinges. In the second case, the frame 104 is very resistant, for example provided with thick metal angles. The corners 12 and 22 then penetrate between the opening portion 102 and the frame 104, and the spacer cylinder 50 is not in maximum travel, it keeps the device in its position to facilitate the work of the cylinder 30 percussion thrust.

L'opérateur actionne alors le troisième bouton 85 placé sur la télécommande 80, ce qui a pour effet de piloter le vérin 30 de poussée à percussion. Comme il a été dit, le vérin de poussée 30 est placé au plus près de la serrure grâce a la rampe de coulissement 14 aménagée sur le fourreau externe 10. Le soufflet élastique 32 du vérin de poussée se gonfle petit à petit sous la pression de l'air et déplace la plaque d'appui 38 contre la partie ouvrante 102 de la porte 100. Une fois la plaque d'appui 38 bien positionnée, l'opérateur appuie de nouveau ou continue d'appuyer sur le troisième bouton 85 afin d'exercer une pression maximum, typiquement d'environ 45KN, sur la partie ouvrante 102 de la porte 100, sensiblement perpendiculairement à celle-ci. Le soufflet 38 continue à se gonfler sous une pression d'air de 15 bars et avec une course d'environ 50 à 200 mm selon le modèle de vérin. La partie ouvrante 102 de la porte se déforme alors sous l'effet à la fois de la poussée perpendiculaire du vérin de poussée 30 mais également de l'écartement longitudinal du vérin d'écartement 50 qui déforme ou désolidarise les montants du châssis 104. Si la porte résiste, l'opérateur peut alors actionner le vérin de poussée 30 plusieurs fois de suite rapidement, par exemple toute les 5 à 10 secondes, voire toutes les 2 secondes environ, afin d'exercer une poussée à percussion répétitive de type va-et-vient sur la porte en vue de faire céder les points de fermeture. Une commande spécifique de percussion peut d'ailleurs être prévue sur la télécommande pour automatiser la frappe du vérin de poussée, avec éventuellement un réglage de la fréquence et de la course avant/arrière. Bien entendu, durant cette opération, le vérin d'écartement reste constamment sous pression. Par ailleurs, le vérin de poussée 30 accepte une déformation angulaire d'environ 20° au maximum grâce au soufflet 38, et ce dans toutes les directions, ce soufflet souple 38 agissant un peu à la manière d'une liaison rotule.The operator then actuates the third button 85 placed on the remote control 80, which has the effect of driving the actuator 30 thrust percussion. As has been said, the thrust cylinder 30 is placed as close as possible to the lock by means of the sliding ramp 14 fitted on the outer sleeve 10. The elastic bellows 32 of the thrust cylinder inflates little by little under the pressure of the air and moves the support plate 38 against the opening portion 102 of the door 100. Once the support plate 38 is properly positioned, the operator presses again or continues to press the third button 85 to exerting a maximum pressure, typically about 45 KN, on the opening portion 102 of the door 100, substantially perpendicular to it. The bellows 38 continues to inflate under an air pressure of 15 bar and with a stroke of about 50 to 200 mm depending on the cylinder model. The part opening 102 of the door is then deformed under the effect of both the perpendicular thrust of the thrust cylinder 30 but also the longitudinal spacing of the spacer cylinder 50 which deforms or separates the amounts of the frame 104. If the door resists, the operator can then actuate the thrust cylinder 30 several times in a row quickly, for example every 5 to 10 seconds, or every 2 seconds or so, in order to exert a repetitive percussion thrust type va-et- comes on the door to give away the closing points. A specific percussion control can also be provided on the remote control to automate the striking of the thrust cylinder, possibly with a frequency adjustment and the forward / backward stroke. Of course, during this operation, the spacer cylinder is constantly under pressure. Furthermore, the thrust cylinder 30 accepts an angular deformation of about 20 ° at most through the bellows 38, and in all directions, this flexible bellows 38 acting somewhat in the manner of a ball joint.

Une fois la porte ouverte, le dispositif 1 reste en général en place, coincé par ses coins 12 et 22 encastrés dans le châssis 104. Il suffit de purger très rapidement les différents vérins à l'aide des soupapes 36 et 56, et notamment le vérin d'écartement à l'aide du premier bouton 26, ce qui a notamment pour effet de débloquer les cliquets 62 qui reviennent en place lorsque la tige de vérin 52 rentre dans le fourreau interne 20 et que les ergots 24 viennent au contact desdits cliquets 62, comme dans la position de repos illustrée par la figure 4.Once the door is open, the device 1 generally remains in place, wedged by its corners 12 and 22 embedded in the frame 104. It is sufficient to purge the various cylinders very quickly using the valves 36 and 56, and particularly the spacer cylinder with the first button 26, which has the effect of unlocking the pawls 62 which return in place when the cylinder rod 52 enters the inner sleeve 20 and the lugs 24 come into contact with said pawls 62, as in the rest position illustrated by the figure 4 .

Dans le cas d'une porte de grande largeur, par exemple industrielle et/ou à double vantaux, ou dans le cas d'un positionnement essentiellement vertical, il est possible de placer la rallonge 40 à l'extrémité du fourreau externe 10, grâce au logement en queue d'aronde 13.In the case of a wide-width door, for example industrial and / or double-leaf, or in the case of a substantially vertical positioning, it is possible to place the extension 40 at the end of the outer sleeve 10, thanks to to the dovetail dwelling 13.

Le dispositif de la présente invention est également utilisable en « aérien », c'est-à-dire par exemple pour ouvrir une fenêtre d'un immeuble de l'extérieur, éventuellement d'un balcon. Pour cela, les deux bras une longe en forme de « Y » munie de mousquetons viennent s'attacher dans les poignées 18 et 28, tandis que la branche principale vient s'attacher par exemple à une rampe de balcon ou à une échelle de pompier. Ainsi, même si le dispositif 1 est désolidarisé de la fenêtre lors de l'enfoncement de celle-ci, il ne risque pas de tomber et par exemple, d'atterrir sur des personnes placés en contre bas de la fenêtre. Cette sécurité supplémentaire est particulièrement utile lorsqu'un flash-over, c'est-à-dire l'explosion d'une boule de feu se propageant à très grande vitesse, sort de la fenêtre lors de son ouverture. Un tel événement, fréquent, est par ailleurs une cause majeure de décès parmi les pompiers.The device of the present invention can also be used in "aerial", that is to say for example to open a window of a building from the outside, possibly a balcony. For this, the two arms a Y-shaped lanyard equipped with carabiners are attached in the handles 18 and 28, while the main branch is attached for example to a balcony railing or a firefighter ladder . Thus, even if the device 1 is disengaged from the window during the depression of the latter, it is not likely to fall and for example, to land on people placed against the bottom of the window. This extra security is particularly useful when a flash-over, that is to say the explosion of a ball of fire propagating at a very high speed, out of the window when it opens. Such a frequent occurrence is also a major cause of death among firefighters.

Le dispositif de la présente invention peut ainsi prendre place dans tous les véhicules de pompier utilisé pour des intervention d'urgence, mais également dans certains véhicules de police ou de gendarmerie intervenant dans le cadre de la répression (drogue, grand banditisme, prise d'otage) ou d'interventions rapides judiciaires.The device of the present invention can thus take place in all firefighting vehicles used for emergency intervention, but also in certain police or gendarmerie vehicles involved in the context of the repression (drugs, organized crime, taking of drugs). hostage) or judicial prompt interventions.

Il se range dans une housse sur mesure, de préférence en matériau ignifugé, pour permettre un transport facile en bandoulière ou à la bretelle sur le lieu de l'opération.It is stored in a custom-made cover, preferably in flame-retardant material, to allow easy transport by shoulder strap or strap at the place of the operation.

Les nombreux avantages de la présente invention par rapport aux solutions de l'art antérieur sont les suivants :

  • Très grande facilité d'utilisation, même dans des conditions extrêmes de visibilité (fumée, faible lumière) ;
  • Grande sécurité du fait de la télécommande qui permet d'agir à distance, à plusieurs mètres de l'ouvrant ;
  • Faible poids du dispositif, environ 12-16 kg, du fait notamment de l'utilisation de titane qui est un matériau à la fois léger, qui ne rouille pas, et qui est très résistant aux chocs et à la chaleur ;
  • Les efforts physiques, à la fois pour porter le dispositif et le manipuler, sont faibles, ce qui permet aux intervenants de conserver leur totale condition physique afin de se concentrer sur le sauvetage des individus à secourir une fois la porte ouverte ;
  • Connexion rapide sur tout type de bouteille d'air comprimé utilisée typiquement par les pompiers ;
  • Le fluide utilisé est incombustible ;
  • L'utilisation d'air évite une manutention complexe comme c'est le cas pour l'utilisation de vérin pneumatique. Il y a peu de risque de panne du dispositif, qui va donc durer longtemps ;
  • Du fait de l'utilisation d'air comprimé, qui plus est toujours disponible dans un camion de pompier, la fréquence de la poussée est très rapide comparativement à un vérin hydraulique très long à purger (plusieurs minutes). Ceci est un gage supplémentaire de sécurité à la fois pour les intervenants (principalement pour les pompiers en cas de feu) mais également pour les personnes secourues dont la vie peut être en sérieux danger ;
  • Peu de détérioration de la porte et de ses montants latéraux, il est parfois même possible de refermer la porte ;
  • Le dispositif peut être placé dans n'importe quelle configuration, par exemple en biais, verticalement ou horizontalement, et fonctionner avec tout type de porte, que ce soit une porte à simple ou double vantaux, une porte de petite largeur, notamment moins large que le dispositif dans son état replié, par exemple de 63 cm, ou une porte de grande largeur, par exemple au-delà de 1 m,
  • Le vérin de poussée étant monté mobile sur une rampe de déplacement, il peut être positionné au meilleur endroit pour accroître les chances d'ouverture rapide de la porte et ne pas perdre de temps ;
  • Il est possible, grâce aux connexion d'air comprimé, de faire fonctionner en parallèle plusieurs dispositif simultanément avec une seule télécommande, afin d'augmenter la force de frappe ;
  • La surface plaque d'appui est suffisamment importante pour éviter que le vérin de poussée ne traverse la porte sans l'ouvrir ;
  • Grâce au soufflet du vérin de poussée qui permet d'accepter une inclinaison allant jusqu'à 20°, la force de frappe de la plaque d'appui reste constante ;
  • Les deux fourreaux ne peuvent pas se déboîter et le vérin d'écartement fonctionne toujours de manière optimale grâce aux cliquets et au fait que le vérin d'écartement pousse par le fond,
  • La puissance de ce dispositif surpasse largement celle des dispositifs de l'art antérieur, le rendant utilisable pour des blindages très élevés,
The many advantages of the present invention over the solutions of the prior art are as follows:
  • Very easy to use, even in extreme visibility conditions (smoke, low light);
  • High security due to the remote control that allows to act remotely, several meters from the opening;
  • Low weight of the device, about 12-16 kg, due in particular to the use of titanium which is a material both lightweight, which does not rust, and is highly resistant to shock and heat;
  • Physical efforts, both to carry the device and to manipulate it, are weak, allowing the responders to maintain their full physical condition in order to focus on rescuing individuals to rescue once the door is opened;
  • Quick connection on any type of compressed air cylinder typically used by firefighters;
  • The fluid used is incombustible;
  • The use of air avoids complex handling as is the case for the use of pneumatic cylinder. There is little risk of failure of the device, which will last for a long time;
  • Due to the use of compressed air, which is still available in a fire truck, the frequency of the thrust is very fast compared to a hydraulic cylinder very long to purge (several minutes). This is an additional guarantee of security for both interveners (mainly for firefighters in case of fire) but also for rescued persons whose lives may be in serious danger;
  • Little deterioration of the door and its side uprights, it is sometimes even possible to close the door;
  • The device can be placed in any configuration, for example at an angle, vertically or horizontally, and operate with any type of door, whether it is a door with single or double leaves, a door of small width, in particular less wide than the device in its folded state, for example 63 cm, or a door of great width, for example beyond 1 m,
  • The thrust cylinder being movably mounted on a displacement ramp, it can be positioned in the best place to increase the chances of rapid opening of the door and not wasting time;
  • It is possible, thanks to the compressed air connections, to operate several devices in parallel simultaneously with a single remote control, in order to increase the striking force;
  • The bearing plate surface is large enough to prevent the thrust cylinder from passing through the door without opening it;
  • Thanks to the bellows of the thrust cylinder which allows to accept an inclination of up to 20 °, the strike force of the backing plate remains constant;
  • The two sleeves can not be dislodged and the spacer cylinder always works optimally thanks to the pawls and the fact that the spacer cylinder pushes by the bottom,
  • The power of this device far surpasses that of the devices of the prior art, making it usable for very high shielding,
