Description

La présente invention concerne un dispositif pour exercer une poussée sur une porte ou toute autre surface plane verticale telle qu'une cloison, à partir de points d'appui externes. La présente invention concerne également un procédé pour exercer une poussée de préférence d'au moins 50 kN sur une porte ou toute autre surface plane verticale à partir de points d'appui externes.The present invention relates to a device for exerting a thrust on a door or any other vertical flat surface such as a partition, from external points of support. The present invention also relates to a method for exerting a thrust preferably of at least 50 kN on a door or other vertical flat surface from external support points.

Plus particulièrement, l'invention concerne un dispositif pour réaliser l'ouverture, le plus rapidement possible, en force, sans choc et en silence, de tout type de porte d'habitation, de locaux industriels ou autres.More particularly, the invention relates to a device for achieving the opening, as quickly as possible, in force, without shock and in silence, any type of residential door, industrial premises or other.

Ces dispositifs sont destinés à être utilisés principalement soit par des organismes de secours tels que sapeurs-pompiers ou protection civile, soit par des brigades spéciales de police ou de gendarmerie.These devices are intended to be used mainly either by relief organizations such as fire brigade or civil protection, or by special brigades of police or gendarmerie.

On connaît déjà des dispositifs de ce genre appelés "pied de biche hydraulique", composés d'un moteur électrique, thermique ou pneumatique, associé à une pompe hydraulique et à un réservoir d'huile. Cette source de pression est reliée, par le biais d'une canalisation souple, à un outil destiné à pousser la porte exclusivement dans le sens de l'ouverture, après avoir engagé l'outil entre le cadre et la porte, et fournir un effort d'écartement par vérin hydraulique.There are already known devices called "hydraulic crowbar", consisting of an electric motor, thermal or pneumatic, associated with a hydraulic pump and an oil tank. This pressure source is connected, by means of a flexible pipe, to a tool intended to push the door exclusively in the direction of opening, after engaging the tool between the frame and the door, and provide a force distance by hydraulic cylinder.

Il existe également un autre outil permettant d'ouvrir des portes, composé de deux vérins disposés perpendiculairement et solidaires l'un à l'autre:

  • ■ un premier vérin positionné horizontalement venant en appui sur les montants verticaux du cadre de la porte, et
  • ■ un deuxième vérin positionné aussi horizontalement mais perpendiculairement au premier vérin et solidaire à celui-ci.
There is also another tool for opening doors, consisting of two cylinders arranged perpendicularly and secured to one another:
  • A first cylinder positioned horizontally bearing on the vertical uprights of the door frame, and
  • ■ a second cylinder positioned as horizontally but perpendicularly to the first cylinder and secured thereto.

Cet outil permet d'exercer un effort de poussée exclusivement dans le sens de l'ouverture, sur la porte au niveau de la serrure.This tool allows to exert a thrust force exclusively in the direction of the opening on the door at the lock.

Les dispositifs mentionnés ci-dessus comportent des inconvénients qui les rendent difficilement exploitables, voire dans certains cas totalement inutilisables par rapport aux portes de sécurité actuelles.The devices mentioned above have drawbacks that make them difficult to exploit, or in some cases totally unusable compared to current security doors.

La majorité des portes de sécurité actuelles est dotée, entre autre, de cornières métalliques disposées tout autour du cadre de la porte, ne permettant en aucun cas de glisser entre la porte et le cadre un quelconque objet, ce qui rend totalement inutilisable le système du type pied de biche hydraulique mentionné ci-dessus.The majority of the current security doors are equipped, among other things, with metal angles arranged all around the door frame, not allowing in no case to slide between the door and the frame any object, which makes completely unusable the system of the type of hydraulic crowbar mentioned above.

Quant à l'autre outil à deux vérins perpendiculaires, le simple fait de devoir être positionné horizontalement à mi-hauteur entre le sol et le haut du cadre de la poste, pour permettre au vérin d'exercer son effort de poussée, est inacceptable dans certains types d'intervention, notamment celles des forces spéciales de police, lesquelles doivent pouvoir, dès l'ouverture de la porte, pénétrer instantanément dans la pièce concernée, et se voient donc le passage barré par le vérin disposé horizontalement et transversalement entre les deux montants verticaux du cadre de la porte.As for the other tool with two perpendicular cylinders, the simple fact of having to be positioned horizontally at mid-height between the ground and the top of the frame of the post, to allow the jack to exert its thrust force, is unacceptable in certain types of intervention, in particular those of the special police forces, which must be able, as soon as the door is opened, to penetrate instantly into the room in question, and thus see the passage blocked by the jack arranged horizontally and transversely between the two. vertical uprights of the door frame.

Il est en outre constaté que les porte de sécurité actuelles, notamment celles munies de 3 ou 5 points de fermeture, nécessitent un important effort de poussée pour obtenir leur ouverture et, dans de nombreux cas, le premier vérin horizontal, n'ayant comme seul point d'appui que le cadre de porte, se trouve éjecté par l'effet de la pression exercée par le deuxième vérin, ce qui rend l'outil totalement inopérant.It is furthermore noted that the current security doors, in particular those provided with 3 or 5 locking points, require a large thrust force to obtain their opening and, in many cases, the first horizontal jack, having as sole point of support that the door frame is ejected by the effect of the pressure exerted by the second cylinder, which makes the tool totally inoperative.

La présente invention vise à fournir un dispositif et procédé d'ouverture de porte améliorés et notamment en remédiant aux inconvénients des dispositifs et procédés actuels décrits ci-dessus.The present invention aims at providing an improved door opening device and method and in particular overcoming the drawbacks of the current devices and methods described above.

Plus particulièrement un but de la présente invention est de fournir un dispositif permettant d'effectuer l'effort de poussée dans le sens habituel d'ouverture d'une porte, mais également dans le sens de sa fermeture, contrairement audit outil à double vérin perpendiculaire.More particularly, an object of the present invention is to provide a device for carrying out the thrust force in the usual direction of opening a door, but also in the direction of its closing, unlike said perpendicular double-jack tool. .

Pour ce faire, la présente invention fournit un dispositif pour exercer une poussée sur une porte ou toute autre surface plane verticale telle qu'une cloison, à partir de points d'appui externes, qui comprend :

  • un vérin de préférence hydraulique, une semelle intermédiaire et une barre d'appui supérieure,
  • ledit vérin comprenant une tige mobile dont une extrémité est fixée de façon articulée, de préférence de façon amovible, sur ladite semelle intermédiaire,
  • ladite barre d'appui supérieure étant fixée de préférence de façon articulée, de préférence encore de façon amovible, à une de ses extrémités sur ladite semelle intermédiaires, et ledit vérin est destiné d'être en appui sur un point d'appui externe inférieur.
To do this, the present invention provides a device for exerting a thrust on a door or other vertical flat surface such as a partition, from external points of support, which comprises:
  • a cylinder preferably hydraulic, a midsole and an upper support bar,
  • said jack comprising a movable rod whose one end is hingedly attached, preferably removably, to said midsole,
  • said upper support bar being preferably fixed in an articulated manner, more preferably removably, at one of its ends on said intermediate sole, and said jack is intended to be supported on a lower external support point.

On entend ici par "point d'appui externe" un point situé à distance de ladite porte ou dite surface plane verticale.Here "external fulcrum" is understood to mean a point situated at a distance from said door or said vertical planar surface.

L'articulation de l'extrémité de la tige mobile dudit vérin sur ladite semelle intermédiaire permet de le disposer en inclinaison de préférence de 20 à 35° par rapport à la verticale, de manière à pouvoir exercer une poussée de préférence d'au moins 50 kN sur ladite semelle intermédiaire lorsque ladite semelle intermédiaire est appliquée en appui sur ladite porte ou surface plane verticale et que ledit vérin est en appui sur un point d'appui externe inférieur, de préférence sur le sol.The articulation of the end of the movable rod of said jack on said midsole makes it possible to arrange it in inclination preferably of 20 to 35 ° with respect to the vertical, so as to be able to exert a thrust preferably of at least 50 kN on said midsole when said midsole is pressed against said door or flat vertical surface and said cylinder is supported on a lower outer support point, preferably on the ground.

De même, l'articulation de ladite barre d'appui supérieure sur ladite semelle intermédiaire permet de disposer ladite barre sensiblement verticalement de manière à pouvoir appliquer son extrémité libre en appui sur un point d'appui externe supérieur constitué de préférence par le cadre de ladite porte ou un plafond, ou une surface plane horizontale située au-dessus de ladite surface plane verticale. On entend ici par "extrémité libre" l'extrémité de ladite barre qui n'est pas fixée à ladite semelle intermédiaire.Similarly, the articulation of said upper support bar on said intermediate sole makes it possible to arrange said bar substantially vertically so as to be able to apply its free end in abutment on an upper external support point constituted preferably by the frame of said door or a ceiling, or a flat horizontal surface located above said vertical planar surface. The term "free end" here means the end of said bar which is not fixed to said midsole.

Dans un mode préféré de réalisation, le dispositif selon l'invention comprend une semelle inférieure, ledit vérin étant fixé de façon articulée de préférence de façon amovible, à son autre extrémité sur ladite semelle inférieure.In a preferred embodiment, the device according to the invention comprises a lower soleplate, said jack being hinged preferably removably fixed at its other end to said bottom flange.

L'articulation dudit vérin sur ladite semelle inférieure permet ainsi de disposer ladite semelle inférieure en appui sur ledit point d'appui externe inférieur, de préférence sur le sol, lorsque ladite semelle intermédiaire fixée à l'extrémité de la tige mobile dudit vérin est en appui sur ladite porte ou dite surface plane verticale, ledit vérin étant en position inclinée par rapport à la verticale.The articulation of said jack on said bottom flange thus allows said bottom flange to rest on said lower outer bearing point, preferably on the ground, when said midsole attached to the end of the movable rod of said jack is in position. support on said door or said vertical planar surface, said cylinder being in an inclined position relative to the vertical.

La présente invention fournit également un procédé pour exercer une poussée de préférence d'au moins 50 kN sur une porte ou toute autre surface plane verticale à partir de points d'appui externes caractérisé en ce qu'on utilise un dispositif selon l'invention.The present invention also provides a method for exerting a thrust preferably of at least 50 kN on a door or other vertical flat surface from external support points characterized in that a device according to the invention is used.

Dans un mode de réalisation particulier du procédé selon l'invention, on réalise les étapes dans lesquelles :

  1. 1) on dispose ledit vérin en inclinaison de préférence de 20 à 35° par rapport à la verticale, avec
    • ladite semelle intermédiaire en appui sur ladite porte ou surface plane verticale, de préférence à proximité de la serrure ou poignée de porte ou des charnières de ladite porte,
    • ledit vérin étant en appui sur un dit point d'appui externe inférieur de préférence le sol, de préférence par l'intermédiaire d'une dite semelle inférieure et
    • ladite barre d'appui supérieure étant en appui contre un dit point d'appui externe supérieur, de préférence un linteau du cadre d'une porte ou un plafond ou une surface plane horizontale située au-dessus de ladite surface plane verticale, et
  2. 2) on fait fonctionner la tige mobile dudit vérin en extension de manière à exercer une dite poussée sur ladite semelle intermédiaire.
In a particular embodiment of the method according to the invention, the steps are carried out in which:
  1. 1) said cylinder is arranged inclined preferably from 20 to 35 ° relative to the vertical, with
    • said midsole resting on said vertical flat door or surface, preferably near the lock or door handle or hinges of said door,
    • said jack being supported on a said lower outer bearing point, preferably the ground, preferably via a said lower sole and
    • said upper support bar being in abutment with a said upper outer support point, preferably a door frame lintel or a ceiling or horizontal flat surface situated above said vertical flat surface, and
  2. 2) the movable rod of said jack is operated in extension so as to exert a said thrust on said midsole.

Par "point d'appui inférieur" on entend ici un point d'appui situé à une hauteur inférieure ou égale à celle du point d'appui de la semelle intermédiaire sur la porte.By "lower bearing point" is meant here a support point located at a height less than or equal to that of the fulcrum of the midsole on the door.

Les différents éléments constitutifs d'un dispositif selon l'invention sont fixés les uns aux autres de façon amovible, c'est-à-dire que les différents éléments constitutifs peuvent être assemblés ou séparés mais réunis dans un ensemble prêt à monter par fixation des différents éléments constitutifs les uns aux autres, à savoir ledit vérin, lesdites semelles intermédiaire et inférieure et ladite barre d'appui supérieure. Ce mode d'assemblage amovible permet également d'envisager l'utilisation d'une partie seulement des éléments constitutifs, notamment ledit vérin fixé de façon articulée et amovible auxdites semelles intermédiaire et inférieure dans les cas où on dispose d'une surface d'appui externe verticale sur laquelle on peut appliquer ladite semelle inférieure d'extrémité dudit vérin, celui-ci étant alors sensiblement disposé horizontalement.The various constituent elements of a device according to the invention are fixed to each other removably, that is to say that the various components can be assembled or separated but joined in a set ready to mount by fixing the different constituent elements to each other, namely said cylinder, said intermediate and lower soles and said upper support bar. This method of removable assembly also makes it possible to envisage the use of only a part of the constituent elements, in particular said jack attached in an articulated and removable manner to said intermediate and lower soles in the cases where a bearing surface is available. external vertical on which one can apply said lower end plate of said cylinder, the latter then being substantially horizontally disposed.

D'autres caractéristiques particulières et avantageuses suivantes d'un dispositif selon l'invention peuvent être prises séparément ou en combinaison :

  • Ledit vérin est un vérin double comprenant un corps de vérin constitué d'une chambre cylindrique renfermant deux tiges mobiles aptes à exercer des poussées orientées en sens opposé l'une de l'autre, les extrémités desdites tiges mobiles du côté extérieur à ladite chambre cylindrique, étant reliées de façon articulée de préférence de façon amovible, respectivement auxdites semelles intermédiaire et inférieure.
  • Ladite barre d'appui supérieure est de longueur ajustable, de préférence constituée par deux tubes télescopiques, la longueur de ladite barre d'appui supérieure étant ajustable par verrouillage de la position relative desdits tubes télescopiques. Cette caractéristique permet d'adapter le dispositif selon l'invention sur des portes de différentes hauteurs d'une part, et d'autre part de réduire l'encombrement du dispositif une fois rangé.
  • Ladite barre d'appui supérieure présente à son extrémité libre, un sabot formant une cornière en équerre. La cornière en équerre est apte à coopérer en appui dans un angle droit du linteau du cadre d'une dite porte.
Other particular and advantageous features of a device according to the invention may be taken separately or in combination:
  • Said cylinder is a double cylinder comprising a cylinder body consisting of a cylindrical chamber containing two movable rods capable of exerting thrusts oriented in opposite directions from one another, the ends of said rods movable from the outer side to said cylindrical chamber , being preferably hingably connected releasably, respectively to said intermediate and lower flanges.
  • Said upper support bar is of adjustable length, preferably constituted by two telescopic tubes, the length of said upper support bar being adjustable by locking the relative position of said telescopic tubes. This feature makes it possible to adapt the device according to the invention to doors of different heights on the one hand, and on the other hand to reduce the size of the device once stored.
  • Said upper support bar has at its free end, a shoe forming an angle bracket. The angle bracket is able to cooperate in support at a right angle of the lintel of the frame of a said door.

Sur la figure 4, ladite semelle inférieure 5 comprend un support plat 51 dont une face destinée à venir en appui sur un point d'appui inférieur 1, de préférence le sol, comprend des éléments anti-dérapants, de préférence des pointes dures 52, et dont l'autre face comprend des moyens d'articulation 53, 54, 45 dudit vérin 4 sur ladite semelle inférieure 5.In FIG. 4, said bottom flange 5 comprises a flat support 5 1 whose face intended to rest on a lower bearing point 1, preferably the floor, comprises non-slip elements, preferably hard points 5 2 , and whose other face comprises hinge means 5 3 , 5 4 , 4 5 of said jack 4 on said bottom flange 5.

Sur les figures 6 on a représenté ladite barre d'appui supérieure 7 de longueur ajustable, constituée par deux tubes télescopiques 72, 73 dont la longueur est ajustable par verrouillage 76 de leur position relative, notamment par l'intermédiaire d'un index de verrouillage 76 coopérant dans des percements 77 du tube supérieur 73 le tube supérieur 73 coulissant à l'intérieur du tube inférieur 72.FIG. 6 shows the said upper support bar 7 of adjustable length consisting of two telescopic tubes 7 2 , 7 3 whose length is adjustable by locking their relative position 7 6 , in particular via a locking index 7 6 cooperating in the holes 7 7 of the upper tube 7 3 the upper tube 7 3 sliding inside the lower tube 7 2 .

Sur les figures 6, est également représenté un sabot 71 en forme d'équerre à l'extrémité libre de ladite barre d'appui, apte à coopérer en appui dans un angle droit d'un linteau de cadre de porte notamment, et une poignée de transport 74.FIGS. 6 also show a shoe 7 1 in the form of a square at the free end of said support bar, capable of cooperating in abutment at a right angle of a door frame lintel in particular, and a carrying handle 7 4 .

Sur les figures 5, on a représenté ladite semelle intermédiaire 6 comprenant un support plat 61 dont une face est destinée à venir en appui sur ladite porte ou surface plane verticale, et comprend des éléments anti-dérapants constitués des pointes dures 62, et l'autre face comprend des moyens d'articulation 63, 64, 45, 75 dudit vérin 4 et de ladite barre d'appui supérieure 7.In FIGS. 5, there is shown said intermediate sole 6 comprising a flat support 6 1 whose one face is intended to bear on said door or vertical flat surface, and comprises non-slip elements consisting of hard points 6 2 , and the other face comprises articulation means 6 3 , 6 4 , 4 5 , 7 5 of said jack 4 and of said upper support bar 7.

Suivant les figures 5, ladite semelle intermédiaire 6 comprend un support plat 61 échancré formant une zone évidée 64 permettant de disposer ladite semelle intermédiaire 6 autour d'un bloc d'une serrure ou d'une poignée de porte 31. Cette configuration est avantageuse car elle garantit l'ouverture de la porte en évitant un simple enfoncement central du panneau constitutif de la porte sans ouverture complète de la porte, laissant donc un passage insuffisant pour le personnel d'intervention.Following Figures 5, said midsole 6 comprises a flat support 6 1 indented forming a recessed area 6 4 allowing to dispose said intermediate soleplate 6 around a block of a lock or a door handle 3 1. This configuration is advantageous because it ensures the opening of the door by avoiding a simple central depression of the component panel of the door without full opening of the door, thus leaving insufficient passage for the intervention personnel.

Lesdites semelles intermédiaire 6 et inférieure 5 comprennent des supports plats ou platines 51, 61 et des moyens d'articulation 53, 54, 63; 64 constitués par des chapes 53, 63 sur une face desdits supports plats 51, 61 ; chapes sur lesquelles sont montés de façon amovible, des ergots escamotables (non représentés) formant axes d'articulation dans des percements 54, 65, 75, 45 desdites chapes et dites extrémités de ladite barre d'appui supérieure 7 et/ou dudit vérin 4, permettant ainsi leur articulation sur lesdites semelles 5, 6.Said intermediate 6 and lower soles 5 comprise flat or platinum supports 5 1 , 6 1 and articulation means 5 3 , 4 4 , 6 3 ; 6 4 constituted by yokes 5 3 , 6 3 on one side of said flat supports 5 1 , 6 1; screeds on which are mounted removably, retractable lugs (not shown) forming hinge pins in bores 5 4 , 6 5 , 7 5 , 4 5 of said yokes and said ends of said upper support bar 7 and / or said cylinder 4, thus allowing their articulation on said flanges 5, 6.

Plus particulièrement, le percement 45 à l'extrémité de la première tige mobile 41 du vérin hydraulique coopère avec des percements 65 des chapes 63 de la semelle intermédiaire 6 et un premier ergot escamotable (non représenté) inséré dans lesdits percements 65 des chapes et 45 de l'extrémité de ladite première tige mobile 41 du vérin, ce qui permet l'articulation dudit vérin par rotation autour de l'axe constitué par ledit premier ergot, notamment lorsque l'on met en place ladite semelle intermédiaire 6 en appui sur une dite porte 3 et que l'on incline ledit vérin 4 en position de 20 à 35° par rapport à la verticale.More particularly, the bore 4 5 at the end of the first movable rod 4 1 of the hydraulic cylinder cooperates with holes 6 5 clevises 6 3 of the intermediate sole 6 and a first retractable lug (not shown) inserted into said holes 6 5 of the clevises and 4 5 of the end of said first movable rod 4 1 of the cylinder, which allows the articulation of said cylinder by rotation about the axis constituted by said first lug, especially when one sets up said midsole 6 resting on a said door 3 and that said cylinder 4 is inclined in position of 20 to 35 ° relative to the vertical.

De même le percement 45 à l'extrémité de la deuxième tige mobile 42 dudit vérin coopère avec des percements 54 des chapes 53 de la semelle inférieure 5, et un deuxième ergot escamotable (non représenté) inséré dans lesdits percements 54 des chapes 53 de la semelle inférieure 43 et de l'extrémité de ladite deuxième tige mobile 42, ce qui permet l'articulation dudit vérin par rotation par rapport à l'axe constitué par ledit deuxième ergot, notamment lorsque l'on met en place ladite semelle inférieure 5 en appui sur le sol 1.Similarly piercing 4 5 à the end of the second movable stem 4 2 of the said cylinder 5 cooperates with openings 4 for screeds 5 3 of the lower flange 5 and a second retractable pin (not shown) inserted into said openings 5 4 yokes 5 3 of the lower plate 4 3 and the end of said second movable rod 4 2, which allows the articulation of the said actuator by rotation relative to the axis constituted by said second lug, in particular when placing said bottom flange 5 resting on the ground 1.

De même, le percement 75 d'extrémité inférieure de ladite barre d'appui 7 coopère avec des percements 65 des chapes 63 de la semelle intermédiaire 6 et un troisième ergot escamotable (non représenté), inséré dans lesdits percements 75, 65, ce qui permet l'articulation de ladite barre d'appui supérieure par rotation de celle-ci par rapport à l'axe constitué par ledit troisième ergot lorsque l'on met en place ladite semelle intermédiaire 6 en appui sur la porte 3.Similarly, the piercing 7 5 bottom end of said support rod 7 cooperates with openings 6 5 6 yokes 3 of the midsole 6 and a third retractable pin (not shown) inserted into said openings 7 5, 6 5 , which allows the articulation of said upper support bar by rotation thereof relative to the axis constituted by said third pin when placing said intermediate sole 6 bears on the door 3 .

Bien évidemment, ces moyens d'articulation du vérin 4 et de la barre d'appui 7 par rapport aux dites semelles 6, 5 sont décrits à titre purement illustratif d'autres moyens d'articulation pouvant être mis en oeuvre sans sortir du cadre de la présente invention.Of course, these means of articulation of the jack 4 and the support bar 7 with respect to said flanges 6, 5 are described purely by way of illustration of other hinge means that can be implemented without departing from the scope of FIG. the present invention.

Sur les figures 3 on a représenté ledit vérin hydraulique avec une poignée de mise en service 82 et une poignée de transport 44.In FIG. 3, the hydraulic cylinder is shown with a commissioning handle 8 2 and a carrying handle 4 4 .

Le vérin hydraulique 4 est un vérin à simple effet comprenant un unique flexible renfermant la canalisation du fluide hydraulique et les canalisations électriques 81. Ledit flexible 81 est relié audit vérin par l'intermédiaire d'une poignée de mise en service 82 dont la rotation déclenche la mise en route de la centrale hydraulique (non représentée) à l'extrémité du flexible. Ces procédé et dispositif de commande et d'alimentation de vérin hydraulique a été décrit dans le brevet d'invention en France FR 94/07680 (publiée sous le n° 2 721 359 ). Cette poignée 82, en combinaison avec le flexible 81 reliant celui-ci à une source de fluide hydraulique, est une liaison électrique entre celle-ci et au moins un contacteur, et permet :

  • la commande par rotation de la poignée 82, de la fermeture dudit contacteur de mise en route de la source de fluide, qui est ainsi mis sous pression,
  • l'alimentation de la chambre dudit vérin situé des côtés des pistons mobiles déplaçant les tiges du vérin, à travers un flexible d'alimentation 81 et ladite poignée 82 reliée audit flexible d'alimentation 81,
  • l'arrêt du déplacement de la tige du vérin et de la source de fluide sous pression, en relâchant la poignée qui revient à une position neutre de repos,
  • l'ouverture d'un clapet de retour du fluide qui a rempli la chambre du vérin par rotation de la poignée en sens inverse de précédemment, et
  • l'évacuation dudit fluide par appui d'un moyen élastique sur l'autre côté des pistons qui se déplacent alors dans la direction opposée à la précédente.
The hydraulic cylinder 4 is a single-acting cylinder comprising a single hose containing the hydraulic fluid pipe and the electrical conduits 8 1 . Said hose 8 1 is connected to said cylinder via a commissioning handle 8 2 whose rotation triggers the start of the hydraulic unit (not shown) at the end of the hose. This method and device for controlling and supplying a hydraulic cylinder has been described in the patent for France FR 94/07680 (published under no. 2,721,359 ). This handle 8 2 , in combination with the hose 8 1 connecting it to a source of hydraulic fluid, is an electrical connection between the latter and at least one contactor, and allows:
  • the rotation of the handle 8 2 , the closing of said contactor for starting the fluid source, which is thus pressurized,
  • supplying the chamber of said jack located on the sides of the moving pistons moving the rods of the jack, through a feed hose 8 1 and said handle 8 2 connected to said feed hose 8 1 ,
  • stopping the movement of the cylinder rod and the source of fluid under pressure, by releasing the handle which returns to a neutral position of rest,
  • the opening of a fluid return valve which has filled the chamber of the jack by rotation of the handle in the opposite direction from previously, and
  • the evacuation of said fluid by pressing an elastic means on the other side of the pistons which then move in the opposite direction to the previous one.

De préférence, on remplit la chambre du vérin située de l'autre côté du piston par rapport à la chambre recevant ledit fluide sous pression par du gaz comprimé qui maintient ainsi une pression d'appui sur le côté correspondant du piston. Il est toutefois possible sans sortir du cadre de la présente invention d'utiliser des vérins à double effet avec deux flexibles d'alimentation en fluide hydraulique qui peuvent respectivement fournir une énergie de mise en oeuvre et respectivement de retour des tiges mobiles.Preferably, the chamber of the cylinder located on the other side of the piston is filled with respect to the chamber receiving said pressurized fluid by compressed gas which thus maintains a bearing pressure on the corresponding side of the piston. However, it is possible without departing from the scope of the present invention to use double-acting cylinders with two hydraulic fluid supply hoses which can respectively provide an energy for implementation and respectively return of the movable rods.

Pour la mise en oeuvre du dispositif selon l'invention comme représenté sur les figures 1 et 2, on réalise les étapes successives suivantes dans lesquelles :

  • on positionne la barre supérieure d'appui en appui sous et contre le lindeau du cadre 2 de la porte 3,
  • on positionne la semelle intermédiaire 6 en appui sur la porte 3 autour de la serrure 31,
  • on positionne la semelle inférieure 5 du vérin hydraulique 4 en appui sur le sol 1, les tiges mobiles du vérin 4 sont sorties de sorte que le vérin prend une inclinaison d'environ 30°. Une fois le dispositif en place, les éléments d'adhérence constitués par les pointes en acier dur 62 et 52 des semelles intermédiaire 6 et inférieure 5, permettent de stabiliser le dispositif en position.
For the implementation of the device according to the invention as represented in FIGS. 1 and 2, the following successive steps are carried out in which:
  • the upper support bar is positioned under and against the frame of the frame 2 of the door 3,
  • the intermediate sole 6 is positioned in abutment on the door 3 around the lock 3 1 ,
  • the lower sole 5 of the hydraulic cylinder 4 is positioned on the ground 1, the movable rods of the cylinder 4 are released so that the cylinder takes an inclination of about 30 °. Once the device is in place, the adhesion elements constituted by the hard steel tips 6 2 and 5 2 of the intermediate flanges 6 and lower 5, stabilize the device in position.

Une fois le dispositif en place, on actionne les tiges mobiles 41 et 42 dudit vérin en extension de manière à exercer une poussée d'au moins 50 kN respectivement sur lesdites semelles intermédiaire 6 et inférieure 5.Once the device in place, it actuates the movable rods 4 1 and 4 2 of said cylinder in extension so as to exert a thrust of at least 50 kN respectively on said intermediate flanges 6 and lower 5.

On exerce une poussée sur une porte blindée pour en forcer l'ouverture en exerçant une poussée sur ladite semelle intermédiaire 6 jusqu'à obtenir une augmentation de l'inclinaison dudit vérin 4 d'un angle d'au moins 3°, de préférence de 5 à 20°. Le vérin se déploie et transmet son effort via la barre d'appui supérieure 7 sur le haut du cadre 2 de la porte ou au plafond. La résistance offerte par le point d'appui supérieur et par le linteau 2 du cadre va permettre d'obtenir un effort de poussée horizontale au niveau de la semelle intermédiaire 6 et permettre de réaliser l'ouverture de la porte.A thrust is exerted on a security door to force the opening by exerting a thrust on said intermediate sole 6 until an increase in the inclination of said cylinder 4 by an angle of at least 3 °, preferably of 5 to 20 °. The cylinder deploys and transmits its force via the upper support bar 7 on the top of the frame 2 of the door or on the ceiling. The resistance offered by the upper fulcrum and the lintel 2 of the frame allow to obtain a horizontal thrust force at the midsole 6 and allow to achieve the opening of the door.

On a décrit l'utilisation de vérin hydraulique mais le vérin peut également être mis sous pression par le biais d'une pompe électrique, thermique, pneumatique ou manuelle.The use of a hydraulic cylinder has been described, but the cylinder can also be pressurized by means of an electric, thermal, pneumatic or manual pump.

Pour les portes de sécurité actuelles, notamment celles munies de 3 ou 5 points de fermeture, on observe que lorsque le dispositif est situé autour des serrures, celles-ci lâchent à partir d'une poussée de vérin d'environ 50 kN obtenue avec une pression hydraulique d'environ 250 bars et créant une inclinaison additionnelle du vérin de 15°, comme représenté sur la figure 2. Cette opération intervenant en quelques secondes, le vérin ne requiert pas d'énergie importante et peut être opérationnel avec un bloc d'alimentation centrale hydraulique ne dépassant pas les 18 kg et pouvant être adapté sur un châssis portable sur le dos.For the current security doors, especially those with 3 or 5 closing points, it is observed that when the device is located around the locks, they release from a cylinder thrust of approximately 50 kN obtained with a hydraulic pressure of about 250 bar and creating an additional inclination of the cylinder of 15 °, as shown in Figure 2. This operation takes place in a few seconds, the cylinder does not require significant energy and can be operational with a block of hydraulic power supply not exceeding 18 kg and can be adapted to a portable chassis on the back.
