Description

La présente invention a pour objet un dispositif de fermeture de portes d'enceintes isolées, notamment phonétiquement et/ou thermiquement, par exemple de véhicules de transport terrestre, ferroviaire, maritime ou aérien, comprenant un volume accessible à une personne, verrouillable depuis l'extérieur.The subject of the present invention is a device for closing doors of isolated enclosures, in particular phonetically and / or thermally, for example of land, rail, sea or air transport vehicles, comprising a volume accessible to a person, lockable from the outside.

Elle trouvera son application dans tous les secteurs industriels ou l'on doit avoir recours à des enceintes isolées comprenant un volume accessible à une personne, à l'intérieur desquelles règne notamment une température sensiblement différente de la température de l'atmosphère extérieure.It will find its application in all industrial sectors where one must have recourse to insulated enclosures comprising a volume accessible to a person, inside of which reigns notably a temperature appreciably different from the temperature of the external atmosphere.

Par exemple, pour distribuer des produits périssables tels que notamment des produits alimentaires depuis leur lieu de production jusqu'à leur lieu de distribution ou directement aux consommateurs, on utilise des enceintes frigorifiques à l'intérieur desquelles les produits sont transportés.For example, to distribute perishable products such as in particular food products from their place of production to their place of distribution or directly to consumers, cold stores are used inside which the products are transported.

L'intérieur de ces enceintes est maintenu à une température compatible avec la conservation de ces produits.The interior of these enclosures is maintained at a temperature compatible with the preservation of these products.

Généralement, en fonction de la nature de ces produits, la température ambiante qui règne à l'intérieur de ces enceintes est comprise entre +10° et -20°C.Generally, depending on the nature of these products, the ambient temperature prevailing inside these enclosures is between + 10 ° and -20 ° C.

Pour maintenir cette température, il est nécessaire que l'enceinte soit parfaitement étanche et isolée thermiquement. C'est la raison pour laquelle elles sont généralement réalisées en des matériaux thermiquement isolants à l'intérieur desquels circule un fluide caloporteur.To maintain this temperature, the enclosure must be perfectly sealed and thermally insulated. This is the reason why they are generally made of thermally insulating materials inside which a heat transfer fluid circulates.

L'accès à l'intérieur de ces enceintes pour le chargement et le déchargement des produits est réalisé au moyen de portes dont la fermeture doit être parfaite pour éviter toute déperdition thermique susceptible de diminuer l'efficacité de l'isolation.Access to the interior of these enclosures for loading and unloading of products is carried out by means of doors, the closing of which must be perfect to avoid any heat loss liable to reduce the efficiency of the insulation.

Pour ce faire, on connaît différents dispositifs de fermeture et de verrouillage d'une conception plus ou moins complexe et d'une mise en oeuvre plus ou moins aisée.To do this, various closing and locking devices are known, of a more or less complex design and of a more or less easy implementation.

C'est ainsi que l'on connaît actuellement un dispositif de verrouillage manuel d'une fermeture qui comporte une poignée articulée sur un support et sollicitée par un ressort dans le sens de l'ouverture. Ce ressort entraîne un loquet qui pénètre dans une gâche lorsque la poignée est en position fermée.This is how a manual locking device for a closure is currently known, which comprises a handle articulated on a support and biased by a spring in the direction of opening. This spring drives a latch which enters a keeper when the handle is in the closed position.

Un cliquet articulé à la poignée autour d'un axe est sollicité par un ressort, vers une position dite d'accrochage dans laquelle le bec du cliquet est en prise avec un tenon solidaire du bâti pour verrouiller la poignée et le loquet dans une position fermée.A pawl hinged to the handle around an axis is biased by a spring, towards a so-called hooking position in which the spout of the pawl is engaged with a lug secured to the frame to lock the handle and the latch in a closed position .

Le tenon présente un méplat dirigé vers le fond de l'échancrure du cliquet en s'éloignant obliquement de l'axe de rotation du dit cliquet.The tenon has a flat directed towards the bottom of the notch of the pawl while moving obliquely away from the axis of rotation of said pawl.

Dans un tel dispositif, ou bien le bec est totalement engagé dans le tenon ou bien il glisse sur le méplat et laisse la poignée se réouvrir. Il en résulte que la poignée ne peut jamais être dans une position mal fermée ou mal verrouillée de sorte que la porte est toujours correctement fermée.In such a device, either the spout is fully engaged in the post or it slides on the flat and lets the handle reopen. As a result, the handle can never be in a badly closed or badly locked position so that the door is always properly closed.

On connaît également un dispositif qui comprend une poignée fixée à l'organe d'actionnement de la serrure qui est pivotée sur un support fixe. Ce support fixe est fixé de manière amovible dans un logement en agissant uniquement depuis l'extérieur au moyen d'une vis engagée dans un trou correspondant du plateau de maintien.A device is also known which comprises a handle fixed to the actuating member of the lock which is pivoted on a fixed support. This fixed support is removably fixed in a housing by acting only from the outside by means of a screw engaged in a corresponding hole in the retaining plate.

L'organe d'actionnement est également enserré depuis l'extérieur dans un logement par une ouverture et il coopère avec un élément du support pour le disposer dans une position angulaire telle qu'il demeure engagé à l'intérieur du dit logement.The actuator is also enclosed from the outside in a housing by an opening and it cooperates with a support element to arrange it in an angular position such that it remains engaged inside said housing.

De tels dispositifs, bien que permettant une fermeture satisfaisante des portes de l'enceinte présentent l'inconvénient d'être uniquement actionnables depuis l'extérieur de l'enceinte.Such devices, although allowing satisfactory closure of the enclosure doors have the drawback of being only actuable from outside the enclosure.

Il en résulte, que si pour une raison non désirée, la porte de l'enceinte se referme, lorsque la personne se trouve à l'intérieur de l'enceinte, elle se trouve enfermée et emprisonnée.It follows that if, for an unwanted reason, the enclosure door closes, when the person is inside the enclosure, he is locked up and imprisoned.

On conçoit qu'en raison notamment de l'isolation phonique de l'enceinte, cette personne ne peut prévenir ou appeler une autre personne à son secours pour lui ouvrir la porte. De ce fait, elle risque de subir de graves troubles. Ces troubles sont d'autant plus graves que le temps de séjour passé à l'intérieur de l'enceinte réfrigérée par la personne est long et que la température ambiante est basse.It is understood that due in particular to the soundproofing of the enclosure, this person cannot prevent or call another person to his rescue to open the door for him. As a result, she risks serious problems. These disorders are all the more serious as the residence time spent inside the refrigerated enclosure by the person is long and the ambient temperature is low.

Pour remédier à ce problème, on a pensé à réaliser des dispositifs de fermeture de porte qui peuvent être ouverts depuis l'intérieur de l'enceinte. Toutefois, de tels dispositifs sont généralement d'une conception complexe et d'un prix élevé. L'une des solutions utilisées consiste à dissocier les différents organes de verrouillage du dispositif en multipliant les axes et les organes de mouvement des pièces de verrouillage. Cette multiplication des organes mécaniques rendent l'ouverture depuis l'intérieur de l'enceinte plus ou moins fiable en fonction du fonctionnement régulier et efficace de ces différents organes.To remedy this problem, it has been thought to produce door closing devices which can be opened from inside the enclosure. However, such devices are generally of complex design and expensive. One of the solutions used consists in dissociating the various locking members of the device by multiplying the axes and the movement members of the locking pieces. This multiplication of mechanical organs makes the opening from inside the enclosure more or less reliable depending on the regular and efficient operation of these different organs.

On connaît également des documents DE-A-2.213.790 et FR-2.584.764 de tels dispositifs permettant un déverrouillage par l'intérieur comprenant :

  • un boîtier à l'intérieur duquel vient se loger, en position fermée, une poignée accessible uniquement de l'extérieur,
  • des moyens pour loger la poignée à l'intérieur du boîtier,
  • des moyens pour verrouiller la porte équipés d'un levier pivotant, dissociés des moyens pour loger la poignée, et d'un taquet, apte à coopérer avec ledit levier,
  • des moyens pour déverrouiller la porte associés par un organe de liaison à des moyens de commande actionnables par une personne depuis l'intérieur de l'enceinte.
Documents DE-A-2,213,790 and FR-2,584,764 are also known of such devices allowing unlocking from the inside, comprising:
  • a housing inside which is housed, in the closed position, a handle accessible only from the outside,
  • means for housing the handle inside the housing,
  • means for locking the door equipped with a pivoting lever, separated from the means for housing the handle, and with a cleat, capable of cooperating with said lever,
  • means for unlocking the door associated by a connecting member with control means actuable by a person from inside the enclosure.

Selon le document DE-A-2.213.790, ce déverrouillage est autorisé par le montage du levier d'accrochage de la gâche sur une platine mobile en translation, actionnée par un bouton à came depuis l'intérieur et repoussé en position normale par un ressort spirale.According to document DE-A-2,213,790, this unlocking is authorized by mounting the catch latching lever on a plate movable in translation, actuated by a cam button from inside and pushed back into normal position by a spiral spring.

La fiabilité d'un tel système repose sur le bon coulissement de la platine, et la bonne efficacité du ressort spirale qui repousse ladite platine en position normale, la fiabilité de ceux-ci étant notamment fonction de la corrosion.The reliability of such a system rests on the good sliding of the plate, and the good efficiency of the spiral spring which pushes said plate back into normal position, the reliability of these being in particular a function of corrosion.

Selon le document FR-A-2.584.764, le levier proprement dit est constitué par un ensemble de deux pièces articulées autour d'un axe commun et coopérant entre elles et maintenues l'une contre l'autre par deux ressorts en épingle. En outre de nécessiter une construction aux pièces multiples, là également la fiabilité dépend de la pression du ressort en épingle qui intervient pour le déverrouillage de l'extérieur et/ou de l'intérieur.According to document FR-A-2,584,764, the lever proper is constituted by a set of two parts articulated around a common axis and cooperating with one another and held against one another by two pin springs. In addition to requiring a construction with multiple parts, there too the reliability depends on the pressure of the pin spring which intervenes for the unlocking from the outside and / or from the inside.

La présente invention a pour objet de remédier aux inconvénients des dispositifs actuellement connus en fournissant un dispositif de fermeture de porte qui peut être facilement déverrouillable depuis l'intérieur de l'enceinte.The object of the present invention is to remedy the drawbacks of the devices currently known by providing a door closing device which can be easily unlocked from inside the enclosure.

Un but de la présente invention est de fournir un dispositif simple, facile à mettre en oeuvre et d'un faible coût.An object of the present invention is to provide a simple device, easy to implement and of low cost.

  • et en ce qu'il comprend des moyens escamotables qui coopèrent avec le logement aptes à bloquer la rotation du levier par le taquet dans une position, et à libérer la rotation du levier dans une autre position, cesdits moyens étant escamotables indépendamment du mouvement de pivotement du levier,
  • et en ce que ledit levier présente une butée coopérant avec lesdits moyens escamotables pour être manoeuvrables depuis l'intérieur de l'enceinte.
To this end, according to the present invention, the device for closing a door, intended for isolated enclosures, comprising an interior volume accessible to a person and lockable from the outside, such as for example refrigerated enclosures, comprising:
  • a housing inside which is housed, in the closed position, a handle accessible only from the outside,

This case is here made of stainless steel but it could be, depending on requirements, made of any other type of suitable material such as aluminum or hard plastic.

Il se compose d'un fond 2 délimité par deux parois latérales 3 et 4 et deux parois transversales 5 et 6. La dimension et la forme du boîtier sont bien entendu variables en fonction des applications mais elle sera toujours suffisante pour recevoir une poignée 7 de manoeuvre qui ici est de forme sensiblement rectangulaire.It consists of a bottom 2 delimited by two side walls 3 and 4 and two transverse walls 5 and 6. The size and shape of the housing are of course variable depending on the applications but it will always be sufficient to receive a handle 7 of maneuver which here is of substantially rectangular shape.

Dans ce mode de réalisation, les parois latérales 3 et 4 et les parois transversales 5 et 6 présentent un rebord faisant saillie perpendiculairement destiné à permettre la mise en place du boîtier 1 dans un logement correspondant de la porte de l'enceinte en association avec les organes de manoeuvre de la porte. Cette mise en place peut être réalisée par toute technique appropriée telle que par rivetage, boulonnage, ou tout autre moyen équivalent.In this embodiment, the side walls 3 and 4 and the transverse walls 5 and 6 have a rim projecting perpendicularly intended to allow the establishment of the housing 1 in a corresponding housing of the enclosure door in association with the door operating parts. This installation can be carried out by any suitable technique such as by riveting, bolting, or any other equivalent means.

La poignée de manoeuvre 7 est ici réalisée dans le même matériau que celui du boîtier 1. Bien entendu, dans d'autres modes de réalisation, elle pourrait être réalisée dans d'autres types de matériaux.The operating handle 7 is here made of the same material as that of the housing 1. Of course, in other embodiments, it could be made of other types of material.

Cette poignée de manoeuvre 7 comporte à l'une des extrémités 8 une ouverture 9 permettant le passage d'une main afin d'autoriser son déplacement depuis une position ouverte jusqu'à une position fermée comme il sera décrit ultérieurement.This operating handle 7 has at one of the ends 8 an opening 9 allowing the passage of a hand in order to allow its movement from an open position to a closed position as will be described later.

Dans sa partie médiane 10, la poignée 7 comporte un barillet 11 d'un type classique actionnable par une clé.In its middle part 10, the handle 7 comprises a barrel 11 of a conventional type actuated by a key.

L'extrémité 12 de la poignée 7 présente un logement 13. A l'intérieur de ce logement 13, sensiblement dans sa partie médiane, est ménagée une lumière oblongue 14. Une pièce en forme d'équerre 15 est fixée par des points de soudure à la base du logement 13 et traverse sur une partie de sa largeur la lumière 14.The end 12 of the handle 7 has a housing 13. Inside this housing 13, substantially in its middle part, an oblong slot is formed 14. A square-shaped part 15 is fixed by welding points at the base of the housing 13 and passes over part of its width the light 14.

L'extrémité 16 du logement 13 comporte au voisinage de son bord transversal 17 un axe d'articulation 18 qui traverse de part en part le dit logement en étant assujetti à chacune de ses extrémités 19, 20 à l'intérieur d'un orifice 21, 22 ménagé dans les parois latérales 23, 24 du logement 13.The end 16 of the housing 13 has, in the vicinity of its transverse edge 17 a hinge pin 18 which passes right through the said housing while being subject to each of its ends 19, 20 inside an orifice 21 , 22 formed in the side walls 23, 24 of the housing 13.

Sur l'une des extrémités 19 de l'axe 18 est monté un organe élastique tel qu'un ressort 25.On one of the ends 19 of the axis 18 is mounted an elastic member such as a spring 25.

L'extrémité 12 de la poignée 7 comporte au voisinage de la paroi 5 du boîtier 1 un palier 26 à l'intérieur duquel sont placés les moyens pour loger la poignée 7 à l'intérieur du boîtier 1.The end 12 of the handle 7 comprises, near the wall 5 of the housing 1, a bearing 26 inside which are placed the means for housing the handle 7 inside the housing 1.

Ces moyens pour loger la poignée 7 sont ici constitués par un axe d'articulation 27 traversant de part en part la poignée 7 et les parois latérales 3 et 4 du boîtier pour venir se solidariser des organes complémentaires de manoeuvre de la porte de l'enceinte.These means for housing the handle 7 are here constituted by a hinge pin 27 passing right through the handle 7 and the side walls 3 and 4 of the housing to come to join the complementary members for operating the door of the enclosure. .

Un couvercle 28 est monté articulé autour de l'axe 18 et recouvre le logement 13 et le barillet 11 en position fermée afin de le protéger.A cover 28 is mounted articulated around the axis 18 and covers the housing 13 and the barrel 11 in the closed position in order to protect it.

En se référant à la figure 2, on voit plus particulièrement le fond 2 du boîtier 1. Ce fond 2 comporte deux rails guides latéraux 30 et 31 destinés à coopérer avec les parois latérales 4 et 5 de la poignée en leur servant de logement lorsque celle-ci est en position fermée.Referring to FIG. 2, we can see more particularly the bottom 2 of the housing 1. This bottom 2 comprises two lateral guide rails 30 and 31 intended to cooperate with the lateral walls 4 and 5 of the handle while serving as their housing when that -this is in position closed.

Une pièce équerre 32 est assujettie par des points de soudure en regard de la lumière oblongue 14 afin de venir, lorsque la poignée est en position fermée, traverser la dite lumière 14 et coopérer avec la pièce de forme complémentaire 15.A square piece 32 is secured by welding points opposite the oblong slot 14 so as to come, when the handle is in the closed position, pass through said slot 14 and cooperate with the piece of complementary shape 15.

Un téton 33 faisant saillie perpendiculairement en matière caoutchoutée est disposé au voisinage de l'équerre 32 pour amortir la poignée 7 lors de sa fermeture et se placer en contact du logement 13 au voisinage du barillet 11 lorsque la dite poignée 7 est en position fermée.A stud 33 projecting perpendicularly from rubber material is arranged in the vicinity of the bracket 32 to cushion the handle 7 when it is closed and to come into contact with the housing 13 in the vicinity of the barrel 11 when said handle 7 is in the closed position.

Les moyens pour verrouiller la porte sont constitués d'une part par une pièce rampe guide 40 et par un taquet 41 associé au barillet 11 monté sur la poignée 7 et, d'autre part, par un levier 42 monté pivotant autour d'un axe 43 à l'intérieur du boîtier 1.The means for locking the door are constituted on the one hand by a guide rail piece 40 and by a cleat 41 associated with the barrel 11 mounted on the handle 7 and, on the other hand, by a lever 42 mounted pivoting about an axis 43 inside the housing 1.

Les moyens pour verrouiller la porte de l'enceinte sont dissociés des moyens pour fermer la poignée 7 de sorte qu'il est possible de les manoeuvrer indépendamment l'un de l'autre. Il est ainsi possible d'ouvrir la porte depuis l'intérieur tout en laissant la poignée 7 en position fermée.The means for locking the door of the enclosure are dissociated from the means for closing the handle 7 so that it is possible to operate them independently of one another. It is thus possible to open the door from the inside while leaving the handle 7 in the closed position.

Le levier 42 est constitué par une pièce qui présente une base 44 et un sommet 45 horizontal solidaire de deux parois latérales 46, 47 symétriques. La face avant 48 de chaque paroi latérale 46, 47 est inclinée de haut en bas, en constituant une rampe guide qui débouche dans une encoche 49 délimitant avec le sommet 45 un logement 50 destiné à recevoir une partie de la poignée de manoeuvre 7 en position verrouillée.The lever 42 is constituted by a part which has a base 44 and a horizontal apex 45 secured to two symmetrical side walls 46, 47. The front face 48 of each side wall 46, 47 is inclined from top to bottom, constituting a guide ramp which opens into a notch 49 delimiting with the top 45 a housing 50 intended to receive a part of the operating handle 7 in position locked.

L'axe 43, traverse de part en part le levier 42 de sorte que celui-ci est monté pivotant autour de cet axe 43. Cet axe 43 est assujetti à chacune de ses extrémités dans un orifice 51, 52 ménagé dans chaque paroi 46-47. Deux ressorts 53, 54 qui sont placés de part et d'autre d'un plan médian vertical sur l'axe 43.The axis 43 passes right through the lever 42 so that the latter is pivotally mounted around this axis 43. This axis 43 is fixed at each of its ends in an orifice 51, 52 formed in each wall 46- 47. Two springs 53, 54 which are placed on either side of a vertical median plane on the axis 43.

Ces ressorts 53, 54 sont assujettis à l'une de leurs extrémités au boîtier 1 et à l'autre de leurs extrémités au sommet du levier 42 de sorte qu'ils accompagnent le mouvement de balancier du levier 42 en sollicitant une force élastique.These springs 53, 54 are subject at one of their ends to the housing 1 and to the other of their ends at the top of the lever 42 so that they accompany the pendulum movement of the lever 42 by requesting an elastic force.

Selon l'invention, les moyens pour déverrouiller la porte de l'enceinte sont constitués par un logement 50 de la partie pivotante bloquante de la poignée au niveau duquel vient se placer le taquet 41 en y étant maintenu par des moyens escamotables 56 depuis l'intérieur de l'enceinte.According to the invention, the means for unlocking the door of the enclosure consist of a housing 50 of the pivoting blocking part of the handle at the level of which the cleat 41 is placed while being held there by retractable means 56 from the inside the enclosure.

Ces moyens escamotables 56 sont constitués par un ressort 57 dont l'une des extrémités 58 est assujettie à la base du levier 42 sur un téton 59 et dont l'autre extrémité 60 doit coopérer avec une butée 61 tout en étant solidaire d'un organe de liaison 62 qui débouche dans un orifice 63 ménagé dans le fond 2 du boîtier 1 pour être manoeuvrable par un dispositif de commande 64 manuel ou non depuis l'intérieur de l'enceinte.These retractable means 56 consist of a spring 57, one of the ends 58 of which is secured to the base of the lever 42 on a stud 59 and the other end of which 60 must cooperate with a stop 61 while being integral with a member link 62 which opens into an orifice 63 formed in the bottom 2 of the housing 1 to be maneuverable by a control device 64 manual or not from inside the enclosure.

Ainsi, il est possible, comme il sera décrit ultérieurement, grâce à l'invention, d'ouvrir facilement la porte de l'enceinte depuis l'intérieur de celle-ci même lorsque cette porte est fermée depuis l'extérieur.Thus, it is possible, as will be described later, by virtue of the invention, to easily open the door of the enclosure from the inside thereof even when this door is closed from the outside.

Ces moyens 56 sont escamotables indépendamment du mouvement de balancier du levier 42 permettant la libération du taquet 41. Cette indépendance et cette dissociation du mouvement des moyens escamotables 56 et du mouvement du balancier du levier 42 permet une ouverture rapide et aisée de la porte depuis l'intérieur de l'enceinte.These means 56 are retractable independently of the balance movement of the lever 42 allowing the release of the cleat 41. This independence and this dissociation of the movement of the retractable means 56 and the movement of the balance of the lever 42 allows the door to be opened quickly and easily from the inside the enclosure.

Bien entendu, d'autres dispositifs équivalents, permettant par un mouvement de rotation, de translation par une combinaison de ces différents mouvements, de rendre escamotable un organe de maintien et de retenue du taquet 41 dans le logement 50 peuvent être utilisés.Of course, other equivalent devices, making it possible by a rotary movement, of translation by a combination of these different movements, to make retractable a member for holding and retaining the cleat 41 in the housing 50 can be used.

Le dispositif conforme à l'invention fonctionne de la manière suivante.The device according to the invention operates in the following manner.

Pour fermer la porte de l'enceinte, on doit tout d'abord loger la poignée 7 dans le boîtier 1. Pour ce faire, on insère sa main à l'intérieur de l'ouverture 9 et on fait pivoter la poignée 7 autour de l'axe 27 depuis une position ouverte dans laquelle elle est disposée sensiblement perpendiculairement au boîtier 1 jusqu'à une position dans lequel elle est sensiblement insérée à l'intérieur du fond 2 du boîtier 1.To close the enclosure door, you must first place the handle 7 in the housing 1. To do this, insert your hand inside the opening 9 and rotate the handle 7 around axis 27 from a open position in which it is arranged substantially perpendicular to the housing 1 to a position in which it is substantially inserted inside the bottom 2 of the housing 1.

Dans cette position, la pièce en équerre 32, pénètre dans la lumière oblongue 14 en venant coopérer avec la pièce complémentaire 15.In this position, the square part 32 enters the oblong opening 14 by coming to cooperate with the complementary part 15.

Dès que la poignée 7 est dans cette position, on verrouille la porte. Cette opération de verrouillage de la porte s'effectue en deux temps.As soon as the handle 7 is in this position, the door is locked. This door locking operation is carried out in two stages.

Tout d'abord, on exerce une pression suffisante au moyen de la main sur la poignée 7 pour qu'au contact de la rampe guide 40 sur les parois latérales inclinées 46, 47 et du levier 42, les ressorts 53, 54 soient sollicités de sorte que le levier 42 pivote autour de l'axe 43 en se levant jusqu'à une position de butée.First, sufficient pressure is exerted by hand on the handle 7 so that in contact with the guide ramp 40 on the inclined side walls 46, 47 and the lever 42, the springs 53, 54 are biased so that the lever 42 pivots about the axis 43 while rising up to a stop position.

Dans cette position, sous l'action de la force de rappel élastique des ressorts 53, 54, le levier 42 se rabat telle qu'une partie de l'ouverture 9 de la poignée de manoeuvre 7 vient se placer à l'intérieur au logement 50.In this position, under the action of the elastic return force of the springs 53, 54, the lever 42 folds down such that part of the opening 9 of the operating handle 7 is placed inside the housing 50.

Ensuite, pour verrouiller totalement la porte, il faut tourner la clé dans le barillet 11 pour faire pivoter le taquet 41 pour qu'il vienne se loger dans le levier 42. Dans cette position, le taquet 41 est placé dans le logement 50 en étant maintenu.Then, to completely lock the door, the key must be turned in the barrel 11 to rotate the cleat 41 so that it comes to be housed in the lever 42. In this position, the cleat 41 is placed in the housing 50 while being maintained.

Il ne reste plus ensuite qu'à ôter la clé du barillet et à rabattre le couvercle 28 de protection.It then only remains to remove the key from the barrel and fold down the protective cover 28.

Selon l'invention, il est possible d'ouvrir facilement et rapidement cette porte depuis l'intérieur de l'enceinte.According to the invention, it is possible to easily and quickly open this door from inside the enclosure.

Pour ce faire, il suffit que la personne exerce depuis l'intérieur de l'enceinte au moyen de l'organe de commande 64 tel qu'une poignée, une force de traction sur l'organe de liaison 62. L'organe de liaison 62 transmet cette force au ressort 57 qui sollicité par cette action, génère un mouvement de rotation d'amplitude limitée par la butée 61 avec laquelle il coopère dans cette position.To do this, it suffices that the person exerts from inside the enclosure by means of the control member 64 such as a handle, a tensile force on the connecting member 62. The connecting member 62 transmits this force to the spring 57 which, by this action, generates a rotation movement of amplitude limited by the stop 61 with which it cooperates in this position.

Par ce mouvement, le ressort 57 libère le taquet 41 qui peut être alors déverrouillé ici par une force de pression exercée sur la base du levier 42.By this movement, the spring 57 releases the cleat 41 which can then be unlocked here by a pressure force exerted on the base of the lever 42.

Sous l'action de cette force, les ressorts 53 et 54 sont sollicités de sorte que le levier 42 pivote autour de l'axe 43 jusqu'à une position de butée. Dans cette position, le taquet 41 est libéré du logement 50 et la partie de l'ouverture 9 de la poignée est libérée de sorte que la porte peut être ainsi ouverte depuis l'intérieur de l'enceinte.Under the action of this force, the springs 53 and 54 are urged so that the lever 42 pivots about the axis 43 to a stop position. In this position, the cleat 41 is released from the housing 50 and the part of the opening 9 of the handle is released so that the door can thus be opened from inside the enclosure.

Bien entendu, d'autres mises en oeuvre de la présente invention pourraient être envisagés sans pour autant sortir du cadre de celle-ci.Of course, other implementations of the present invention could be envisaged without departing from the scope thereof.

Par exemple, les figures 5 à 8 illustrent un second mode de réalisation présentant une variante dans la poignée de manoeuvre.For example, Figures 5 to 8 illustrate a second embodiment showing a variant in the operating handle.

On retrouve un boîtier 101, présentant un fond 102 et des parois latérales et transversales 103-106, à l'intérieur duquel vient se loger une poignée 107 de manoeuvre, présentant à une de ses extrémités 108 une ouverture 109 pour la manoeuvre manuelle.There is a housing 101, having a bottom 102 and lateral and transverse walls 103-106, inside of which is housed a handle 107 for operating, having at one of its ends 108 an opening 109 for manual operation.

Le système de rotation de la poignée par rapport au boîtier est semblable au mode précédent et son verrouillage est autorisé à partir d'un barillet à clef 111, protégé éventuellement par un couvercle 128. On retrouve également un axe d'articulation 127 traversant de part en part le boîtier 101 et la poignée 107.The system for rotating the handle relative to the housing is similar to the previous mode and its locking is authorized from a key cylinder 111, possibly protected by a cover 128. There is also a hinge pin 127 passing through apart the housing 101 and the handle 107.

Les moyens pour verrouiller la porte sont constitués d'une part par une rampe guide 140 prévue sur la poignée dans sa partie médiane, et formée par un évidement de celle-ci, et un taquet 141 associé au barillet 111 et, d'autre part, par un levier de verrouillage 142 monté pivotant autour d'un axe 143 à l'intérieur du boîtier 101, tel qu'illustré à la figure 6.The means for locking the door consist, on the one hand, of a guide ramp 140 provided on the handle in its middle part, and formed by a recess of the latter, and a cleat 141 associated with the barrel 111 and, on the other hand , by a locking lever 142 pivotally mounted about an axis 143 inside the housing 101, as illustrated in FIG. 6.

Le levier 142 est particulièrement représenté à la figure 8 en position fermée, en traits pleins, et en position ouverte, en traits mixtes. A sa partie supérieure, il présente un bec 144 qui coopère avec la rampe guide 140 de la poignée contre laquelle il est pressé par le ou les ressorts de rappel 145.The lever 142 is particularly shown in FIG. 8 in the closed position, in solid lines, and in the open position, in dashed lines. At its upper part, it has a spout 144 which cooperates with the guide ramp 140 of the handle against which it is pressed by the return spring or springs 145.

Lorsque l'on appuie sur la partie externe saillante 146 du levier, le ressort 145 est comprimé et le bec 144 échappe de la rampe guide 140 lors de la rotation du levier autour de l'axe 143. Cette manoeuvre est autorisée de l'extérieur si le taquet 141 du barillet est en position déverrouillée, telle que représentée en traits mixtes à la figure 6.When the external part is pressed projection 146 of the lever, the spring 145 is compressed and the spout 144 escapes from the guide ramp 140 during the rotation of the lever around the axis 143. This operation is authorized from the outside if the stopper 141 of the barrel is in position unlocked, as shown in phantom in Figure 6.

En effet, au contraire si le taquet 141 est en position verrouillée, telle que représentée en traits forts à la figure 6, il n'est pas possible d'enfoncer la partie externe 146 grâce aux moyens escamotables 156 de la présente invention, mais il sera néanmoins possible d'agir de l'intérieur sur le levier 142.Indeed, on the contrary if the stopper 141 is in the locked position, as shown in strong lines in FIG. 6, it is not possible to push in the external part 146 thanks to the retractable means 156 of the present invention, but it it will nevertheless be possible to act from the inside on lever 142.

A cet égard, le levier 142 présente, dans sa partie en vis-à-vis avec le taquet 141, un logement 150 prévu pour coopérer avec le taquet et les moyens escamotables, dont les dimensions sont supérieures à celles du taquet, c'est-à-dire que ce dernier pourra traverser le dit logement. Cependant, en position normale, ce mouvement est empêché par un ressort en épingle 157 solidaire du levier 142 par l'une de ses branches, notamment par un téton d'articulation 158 et une patte de blocage 159.In this regard, the lever 142 has, in its part opposite the cleat 141, a housing 150 provided to cooperate with the cleat and the retractable means, the dimensions of which are greater than those of the cleat, that is to say that the latter can cross said housing. However, in the normal position, this movement is prevented by a pin spring 157 secured to the lever 142 by one of its branches, in particular by a hinge pin 158 and a locking tab 159.

L'autre branche 160 prend appui de part et d'autre du logement 150, tel que le montre la figure 6, et s'oppose à la rotation du levier 142, tel que le montrent les figures 7 et 8, si le taquet 141 lui est supérieur. En effet, dans ce cas, la branche 160 est prise en sandwich entre le taquet 141 et la partie externe 161 du levier.The other branch 160 is supported on either side of the housing 150, as shown in Figure 6, and opposes the rotation of the lever 142, as shown in Figures 7 and 8, if the stopper 141 is superior to him. Indeed, in this case, the branch 160 is sandwiched between the cleat 141 and the outer part 161 of the lever.

Cela étant, la branche 160 peut être mise en rotation, comme le montrent les traits mixtes de la figure 6, grâce au dispositif de commande 164 manoeuvrable depuis l'intérieur dont le fonctionnement permet deux temps successifs.That said, the branch 160 can be rotated, as shown in the broken lines in Figure 6, thanks to the control device 164 operable from the inside whose operation allows two successive times.

Le dit dispositif 164 se présente par exemple sous la forme d'un lien souple assujetti à l'extrémité 162 de la branche 160 de l'épingle 157 puis guidé dans le levier, notamment par les pattes 163 et 166, et débouche vers l'intérieur, notamment au-travers de l'orifice 165 prévu à cet effet dans le boîtier 101.Said device 164 is for example in the form of a flexible link secured to the end 162 of the branch 160 of the pin 157 then guided in the lever, in particular by the legs 163 and 166, and opens out towards the inside, in particular through the orifice 165 provided for this purpose in the housing 101.

Lorsque l'on exerce une traction sur le lien souple 164, la branche 160 du ressort en épingle va se déplacer, comme le montre la figure 6, pour dégager le taquet 141 et permettre la rotation éventuelle du levier 142 autour de l'axe 143, puis en continuant la dite rotation, la branche 160 va prendre appui sur la patte 163 et créer un couple de rotation par la patte 166 pour entraîner en rotation le levier autour de l'axe 143 et autoriser par suite le déverrouillage de l'intérieur, cela même si le dispositif est fermé à clef de l'extérieur.When you pull the link flexible 164, the branch 160 of the hairpin spring will move, as shown in FIG. 6, to release the cleat 141 and allow possible rotation of the lever 142 around the axis 143, then continuing said rotation, the branch 160 will be supported on the tab 163 and create a torque by the tab 166 to rotate the lever around the axis 143 and consequently authorize unlocking from the inside, even if the device is locked from the outside.
