This arrangement is of the type comprising a mechanism for immobilising the movable element in its position of closure and for releasing this member, which mechanism is mounted on the movable member and provided with a lock bolt (8) designed to engage in a striker plate member mounted on the fixed structure surrounding the opening, and a bearing bar (2) for actuating the lock bolt (8) which can move in a support (1) secured to the moving member, between a pushed-in position entraining the withdrawal of the lock bolt (8) from the said striker plate member and an out position in which the locking bolt is engaged in the latter. The arrangement is characterised in that it comprises a device (11) for keeping the bar (2) in its position in which it is pushed into the housing (1), which is provided with specifically-controlled means (12) for bringing into service. The invention can be used for anti-panic doors.

Description

Lfinvention concerne un agencement de verrouillage notamment antipanique d'un organe mobile de fermeture d'une ouverture, tel qu'une porte, du type comprenant un mécanisme de blocage de l'organe mobile dans sa position de fermeture et de libération de cet organe qui est monté sur l'organe mobile et pourvu d'un pêne adapté pour s'engager dans un organe de gâche monté sur la structure fixe de l'ouverture, et une barre d'appui pour l'actionnement du pêne, mobile dans un support entre une position enfoncée entraînant le retrait du pêne dudit organe de gache et une position sortie d'engagement de pêne dans ce dernier. The invention relates to a locking arrangement, in particular antipanic, of a movable member for closing an opening, such as a door, of the type comprising a mechanism for locking the movable member in its closed position and for releasing this member which is mounted on the movable member and provided with a bolt adapted to engage in a strike member mounted on the fixed structure of the opening, and a support bar for actuating the bolt, movable in a support between a depressed position causing the bolt to be withdrawn from said striker member and an extended position for engaging the bolt in the latter.

Les agencements connus de ce type présentent l'inconvénient que la barre d'appui revient chaque fois obligatoirement dans sa position sortie lorsque la force d'appui exercée sur la barre cesse. Known arrangements of this type have the drawback that the support bar must return to its extended position each time when the support force exerted on the bar ceases.

La présente invention a pour but de proposer un agencement de blocage notamment d'une barre d'appui antipanique qui remédie à l'inconvénient de l'agencement connu. The object of the present invention is to propose a blocking arrangement, in particular of a panic support bar which overcomes the drawback of the known arrangement.

Pour atteindre ce but, l'agencement selon l'invention comprend un dispositif de retenue de la barre dans sa position enfoncée, qui est pourvu de moyens de mise en service à commande spécifique. To achieve this object, the arrangement according to the invention comprises a device for retaining the bar in its depressed position, which is provided with commissioning means with specific command.

Selon une caractéristique avantageuse de l'invention, le dispositif de retenue est réalisé sous forme d'un mécanisme actionnable par un organe d'actionnement tel qu'une clé. According to an advantageous characteristic of the invention, the retaining device is produced in the form of a mechanism which can be actuated by an actuating member such as a key.

Selon une autre caractéristique avantageuse de l'invention, le dispositif de retenue comprend un organe de verrouillage monté mobile sur la barre d'appui ou le support de celle-ci, entre une position dans laquelle il s'engage dans un organe de retenue solidaire dudit support ou de la barre d'appui. According to another advantageous characteristic of the invention, the retaining device comprises a locking member movably mounted on the support bar or the support thereof, between a position in which it engages in an integral retaining member of said support or of the support bar.

Selon encore une autre caractéristique avantageuse de l'invention, l'organe de verrouillage est monté mobile sur la barre d'appui. According to yet another advantageous characteristic of the invention, the locking member is mounted movably on the support bar.

L'invention sera mieux comprise, et d'autres buts, caractéristiques, détails et avantages de celle-ci appara1tront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention, et dans lequel
- la figure 1 est une vue en perspective, partiellement éclatée, d'un agencement de verrouillage antipanique avec arrachement partiel et partiellement éclaté d'un agencement de verrouillage antipanique selon l'invention
- la figure 2 est une vue en perspective, avec arrachement partiel et à plus grande échelle du dispositif de retenue de la barre d'appui de l'agencement selon la figure 1, dans la position sortie de la barre ; et
- la figure 3 est une vue similaire à celle de la figure 2 mais montre le dispositif de retenue dans sa position de maintien de la barre dans la position enfoncée.The invention will be better understood, and other objects, characteristics, details and advantages thereof will appear more clearly during the explanatory description which follows, made with reference to the appended schematic drawings given solely by way of example illustrating a embodiment of the invention, and in which
- Figure 1 is a perspective view, partially exploded, of a panic locking arrangement with partial cutaway and partially exploded of a panic locking arrangement according to the invention
- Figure 2 is a perspective view, partially broken away and on a larger scale of the retaining device of the support bar of the arrangement according to Figure 1, in the extended position of the bar; and
- Figure 3 is a view similar to that of Figure 2 but shows the retainer in its position for holding the bar in the depressed position.

La figure 1 montre l'agencement de verrouillage antipanique d'une porte (non représentée) qui comporte un bottier 1 de forme allongée et une barre d'appui 2 montée mobile en translation dans le bottier, entre une position sortie et une position enfoncée, à l'encontre de ressorts de rappel 3. Une telle barre d'appui est connue en soi. FIG. 1 shows the anti-panic locking arrangement of a door (not shown) which comprises a case 1 of elongated shape and a support bar 2 mounted movable in translation in the case, between an extended position and a depressed position, against return springs 3. Such a support bar is known per se.

Dans l'exemple représenté elle est guidée dans des trous oblongs inclinés 4 d'étrier en forme de U 5 qui sont solidaires du bottier 1. L'étrier est fixé par sa base sur le fond du boîtier. Les trous oblongs inclinés 4 sont pratiqués dans les branches de l'étrier.In the example shown, it is guided in oblique oblong holes 4 of a U-shaped stirrup 5 which are integral with the case 1. The stirrup is fixed by its base to the bottom of the case. The inclined oblong holes 4 are made in the branches of the stirrup.

L'extrémité de la barre d'appui 2, qui est située à gauche du dessin porte un organe de commande 7 d'un mécanisme d'actionnement d'un pêne 8. Ce mécanisme est enfermé dans un boltier 9. Le pêne 8 est mobile entre deux positions, à savoir une position sortie représentée à la figure 1 dans laquelle il peut s'engager dans un organe de gâche (non représenté) et une position retirée dans le bottier. Le bottier 1 est adapté pour être fixé sur la porte et l'organe de gâche sera monté sur la structure d'encadrement de celle-ci. The end of the support bar 2, which is located to the left of the drawing, carries a control member 7 of a mechanism for actuating a bolt 8. This mechanism is enclosed in a bolt holder 9. The bolt 8 is movable between two positions, namely an extended position shown in Figure 1 in which it can engage in a striker (not shown) and a position removed in the case. The boot 1 is adapted to be fixed on the door and the strike member will be mounted on the frame structure thereof.

L'agencement de verrouillage représenté comporte un dispositif de retenue de la barre d'appui 2 dans sa position enfoncée. Ce dispositif porte le symbole de référence général 11 et est montré plus en détail aux figures 2 et 3. Le dispositif 11 est réalisé sous forme d'un mécanisme actionnable par une clé et monté sur la face avant de la barre 2. Le mécanisme comprend un organe 14 qui est monté rotatif dans un élément cylindrique solidaire de la barre en traversant celui-ci axialement. The locking arrangement shown comprises a device for retaining the support bar 2 in its depressed position. This device bears the general reference symbol 11 and is shown in more detail in FIGS. 2 and 3. The device 11 is produced in the form of a mechanism actuable by a key and mounted on the front face of the bar 2. The mechanism comprises a member 14 which is rotatably mounted in a cylindrical element integral with the bar by passing through the latter axially.

L'extrémité inférieure libre de l'élément rotatif 14 porte un support en forme d'un L 15 dont la branche verticale s'étend perpendiculairement à l'axe de l'élément 14 tandis que la partie horizontale 17 formant le pied du L s'étend parallèlement à cet axe, à une certaine distance de celle-ci. Dans la position normale du dispositif 11, représenté à la figure 2, le support 15 est orienté parallèlement à l'axe de la barre 2, avec le pied 17 orienté vers le fond du bottier 1. La partie 17 porte à son extrémité libre deux pattes 18 qui logent un axe 19 sur lequel est monté pivotant, à l'encontre d'un ressort 20, une pièce allongée 21 qui présente un profil en forme d'un U ouvert en direction de la partie 16 du support 15.The free lower end of the rotary element 14 carries a support in the form of an L 15 whose vertical branch extends perpendicular to the axis of the element 14 while the horizontal part 17 forming the foot of the L s 'extends parallel to this axis, at a certain distance from it. In the normal position of the device 11, shown in FIG. 2, the support 15 is oriented parallel to the axis of the bar 2, with the foot 17 oriented towards the bottom of the shoemaker 1. The part 17 carries at its free end two lugs 18 which house an axis 19 on which is pivotally mounted, against a spring 20, an elongated piece 21 which has a U-shaped profile open in the direction of part 16 of the support 15.

A son extrémité libre, la base de la pièce 20 se prolonge par une partie en forme de languette 22. La languette 22 est coudée deux fois et ce termine par une portion 23 latéralement décalée en direction du fond du bottier et parallèle à celui-ci. Cette position constitue la position de repos de la pièce 20 dans laquelle celle-ci est repoussée par le ressort 20. La pièce 21 peut pivoter à l'encontre de ce ressort, dans la direction de la flèche
F1, ctest-à-dire en direction de la branche 16 du support en L 15. Le fond du bottier 1 porte sur sa face inférieure une bride 25 en forme d'un U. Les extrémités des branches de la bride sont solidaires du fond et la base 26 est parallèle à celui-ci.La bride est inclinée par rapport à l'axe du bottier selon un angle g et disposée de façon que la portion 23 de la languette 22 puisse venir en dessous de la base 26 de la bride 25, comme le montre la figure 3, lorsque l'élément rotatif 14 de la serrure occupe la position dans laquelle la languette 22 s'étend parallèlement à l'axe du bottier 1 et de la barre 2 et puisse être dégagé de la bride lorsque l'élément rotatif 14 est amené par la clé 12 à tourner dans la direction de la flèche F2 selon un angle correspondant par exemple à un quart de tour. Cette position n'est pas représentée. La base 26 de la bride 25 comprend une excroissance 27 qui fait saillie vers le fond du boitier pour éviter un dégagement non souhaité de la languette 22 de la bride, par exemple sous l'effet de vibrations.At its free end, the base of the piece 20 is extended by a tongue-shaped part 22. The tongue 22 is bent twice and this ends with a portion 23 laterally offset in the direction of the bottom of the shoemaker and parallel to it . This position constitutes the rest position of the part 20 in which the latter is pushed back by the spring 20. The part 21 can pivot against this spring, in the direction of the arrow
F1, that is to say towards the branch 16 of the L-shaped support 15. The bottom of the boot 1 carries on its underside a flange 25 in the shape of a U. The ends of the branches of the flange are integral with the bottom and the base 26 is parallel to it. The flange is inclined relative to the axis of the shoemaker at an angle g and arranged so that the portion 23 of the tongue 22 can come below the base 26 of the flange 25, as shown in FIG. 3, when the rotary element 14 of the lock occupies the position in which the tongue 22 extends parallel to the axis of the housing 1 and of the bar 2 and can be released from the flange when the rotary element 14 is caused by the key 12 to rotate in the direction of the arrow F2 at an angle corresponding for example to a quarter turn. This position is not shown. The base 26 of the flange 25 includes a protrusion 27 which projects towards the bottom of the housing to avoid unwanted disengagement of the tongue 22 from the flange, for example under the effect of vibrations.

On décrira ci-après le fonctionnement du dispositif 11 de retenue de la barre d'appui 2 dans sa position enfoncée. The operation of the device 11 for retaining the support bar 2 in its depressed position will be described below.

La figure 2 montre le dispositif de retenue dans sa position normale dans laquelle la languette 22 s'étend parallèlement à l'axe du bottier, la barre d'appui 2 occupant sa position sortie. Lorsque l'on souhaite enfoncer la barre, la portion 23 de la languette 20 vient en appui sur la base 26 de la bride 25. La barre 2 peut quand même être enfoncée à fond puisque la pièce 21 s'efface en pivotant autour de l'axe 19 à l'encontre du ressort 20. Si l'on souhaite que la barre d'appui soit retenue dans sa position enfoncée à fond, on tourne la clé 12 d'un quart de tour dans le sens des aiguilles d'une montre, c'est-à-dire dans le sens de la flèche F3. Puis on appui sur la barre et tourne la clé 12 d'un quart de tour en sens inverse. La portion 23 de la languette 22 s'engage lors de ce mouvement de rotation de la clé dans la bride 25, sous la base 26, comme le montre la figure 3. Dans cette position la barre reste bloquée dans sa position enfoncée. La clé 12 peut être enlevée de sa serrure. Figure 2 shows the retainer in its normal position in which the tongue 22 extends parallel to the axis of the shoemaker, the support bar 2 occupying its extended position. When it is desired to push the bar in, the portion 23 of the tongue 20 comes to bear on the base 26 of the flange 25. The bar 2 can still be pushed in fully since the part 21 is erased by pivoting around the axis 19 against the spring 20. If it is desired that the support bar be retained in its fully depressed position, the key 12 is turned a quarter of a turn clockwise shows, i.e. in the direction of arrow F3. Then we press the bar and turn the key 12 a quarter turn in the opposite direction. The portion 23 of the tongue 22 engages during this rotational movement of the key in the flange 25, under the base 26, as shown in Figure 3. In this position the bar remains locked in its depressed position. The key 12 can be removed from its lock.

Etant donné que le verrouillage de la barre d'appui 2 dans sa position enfoncée et son déverrouillage nécessitent l'utilisation d'un clé 12, ces opérations ne peuvent être exercées que par une personne en pocession de la clé, ce qui assure une protection efficace contre tout actionnement frauduleuse du dispositif de retenue 11. Par contre le fonctionnement normal de la barre d'appui n'est nullement gêné par ce dispositif, étant donné sa faculté de s'effacer grâce à la possibilité de la languette de verrouillage 22 de pivoter autour de son axe 19. Since locking the support bar 2 in its depressed position and unlocking it requires the use of a key 12, these operations can only be carried out by a person in possession of the key, which provides protection effective against any fraudulent actuation of the retaining device 11. On the other hand, the normal operation of the grab bar is in no way hampered by this device, given its ability to be erased thanks to the possibility of the locking tab 22 of pivot around its axis 19.
