Description

L'invention se situe dans le domaine de la serrurerie.The invention lies in the field of locksmithing.

La présente invention concerne plus précisément un boitier de serrure équipé d'un plastron anti-panique.The present invention more specifically relates to a lock case equipped with an anti-panic bib.

Dans un certain nombre de locaux professionnels, la réglementation impose, pour des raisons de sécurité, que les boitiers de serrure installés sur les portes de ces locaux soient équipés d'un plastron anti-panique. Un tel plastron est une plaque ou un levier qui permet d'ouvrir la porte, sans avoir à manoeuvrer la serrure à l'aide d'une clé.In a number of business premises, the regulations require, for security reasons, that the lock boxes installed on the doors of these premises are equipped with a panic bumper. Such a plastron is a plate or a lever that opens the door, without having to operate the lock with a key.

Un exemple particulier d'application concerne les postes électriques ou postes de transformation industriels ou semi-privés, qui sont des locaux reliés au réseau électrique, notamment à haute tension et qui contiennent des appareils permettant de modifier et généralement d'abaisser la tension du courant électrique, en vue de sa distribution aux usagers finaux.A particular example of application relates to electrical substations or industrial or semi-private substations, which are premises connected to the electrical network, including high voltage and contain devices for changing and generally lowering the voltage of the current electric, for distribution to end-users.

Les portes d'accès à ces postes de transformation sont équipées de boitiers de serrure, de sorte qu'il est possible de les fermer à clé, afin d'empêcher ainsi l'entrée de toute personne non autorisée, et d'éviter les accidents par électrocution.The access doors to these transformer stations are equipped with lock boxes, so that it is possible to lock them in order to prevent the entry of any unauthorized person, and to avoid accidents. by electrocution.

Les agents de maintenance qui interviennent à l'intérieur de ces postes de transformation ont la clé et peuvent entrer. Toutefois, dans la mesure où ils ne sont pas des agents EDF habilités, la réglementation impose que les boitiers de serrure soient équipés d'un plastron anti-panique du côté intérieur du local, afin qu'en cas d'accident, notamment de brûlures sur les mains, l'agent de maintenance puisse ouvrir la porte de l'intérieur, en poussant simplement sur le plastron avec son corps et sans avoir à manipuler une clé.Maintenance agents who work inside these transformer stations have the key and can enter. However, to the extent that they are not authorized EDF agents, the regulations require that the lock cases be equipped with a panic-proof front plate on the inside of the room, so that in the event of an accident, including burns. on the hands, the maintenance officer can open the door from the inside, simply pushing on the front plate with his body and without having to handle a key.

On connaît déjà d'après l'état de la technique, de tels boitiers de serrure à plastron dont le cylindre (ou barillet) est du type cylindre rond.Already known from the state of the art, such plastron lock boxes whose cylinder (or cylinder) is of the round cylinder type.

Un tel boitier de serrure est par exemple connu du FR 1 280 695 A .Such a lock case is for example known from the FR 1 280 695 A .

Pour mémoire, on rappelle ici que le cylindre est le dispositif qui permet de déplacer le pêne de la serrure grâce à une clé.For the record, it is recalled here that the cylinder is the device that moves the bolt of the lock with a key.

Ce type de cylindre est très spécifique, n'est commercialisé que par peu de fabricants et de ce fait est cher. En outre, en cas de perte d'une clé, le renouvellement de celle-ci est également cher et complexe. Un méchanisme de manoeuvre de porte du type anti-panique avec un cylindre de type européen est connu du WO 02/25041 A1 .This type of cylinder is very specific, is marketed by few manufacturers and therefore is expensive. In addition, in case of loss of a key, the renewal of it is also expensive and complex. An anti-panic door maneuver mechanism with a European type cylinder is known from WO 02/25041 A1 .

Un objectif de l'invention est de fournir une alternative à un boitier de serrure équipé d'un plastron.An object of the invention is to provide an alternative to a lock case equipped with a plastron.

A cet effet, l'invention concerne un boitier de serrure équipé d'un plastron anti-panique.For this purpose, the invention relates to a lock case equipped with an anti-panic plastron.

Le dispositif conforme à l'invention va maintenant être décrit en faisant référence à la figure 1.The device according to the invention will now be described with reference to the figure 1 .

Sur celle-ci, on peut voir les différents éléments qui constituent respectivement un boitier de serrure 1 et un plastron anti-panique 2.On this one, we can see the different elements which respectively constitute a lock casing 1 and a panic plate 2.

Le boitier 1 comprend un coffre 3, obturé par un couvercle 4 ou "foncet". Un pêne 5 est monté coulissant à l'intérieur du coffre 3.The housing 1 comprises a trunk 3, closed by a cover 4 or "funcet". A bolt 5 is slidably mounted inside the trunk 3.

Un demi-cylindre 6, visible uniquement sur les figures 8 à 10 est inséré à l'intérieur du boitier 1.A half-cylinder 6, visible only on Figures 8 to 10 is inserted inside the case 1.

Le plastron anti-panique 2 comprend une poignée 7, sur la face supérieure de laquelle est fixé un poussoir 8 et sur la face inférieure de laquelle est fixé un profilé en L 9 et un ressort hélicoïdal 73.The anti-panic plate 2 comprises a handle 7, on the upper face of which is fixed a pusher 8 and on the lower side of which is fixed an L-shaped section 9 and a helical spring 73.

Le boitier 1 est monté dans une réservation prévue à cet effet dans la porte, de façon que le demi-cylindre et l'orifice d'insertion de la clé soient accessibles du côté extérieur de la porte, que le plastron 2 soit disposé côté intérieur de la porte et que le pêne puisse coulisser latéralement pour être reçu dans une gâche située dans le bâti de la porte.The housing 1 is mounted in a reservation provided for this purpose in the door, so that the half-cylinder and the insertion hole of the key are accessible from the outside of the door, the plastron 2 is arranged on the inside of the door and that the bolt can slide laterally to be received in a keeper located in the frame of the door.

De préférence, le coffre 3, le foncet 4, le pêne 5, la poignée 7, le poussoir 8 et le profilé en L 9 sont fabriqués à partir de tôles métalliques ou flancs, de préférence en acier inoxydable pour résister à la corrosion. Ces différentes pièces sont obtenues par découpage, pliage et poinçonnage.Preferably, the trunk 3, the key 4, the bolt 5, the handle 7, the pusher 8 and the L-section 9 are made from metal sheets or flanks, preferably stainless steel to resist corrosion. These different pieces are obtained by cutting, folding and punching.

Le coffre 3 va maintenant être décrit plus en détails en faisant référence aux figures 3 et 8.The trunk 3 will now be described in more detail with reference to figures 3 and 8 .

Le coffre 3 comprend un fond rectangulaire 30 ou "palâtre", bordé sur ses quatre côtés par des cloisons s'étendant à angle droit sur une faible hauteur, à savoir deux cloisons longitudinales 31 et 32, une cloison arrière 33 et une cloison avant opposée 34 ou "têtière".The trunk 3 comprises a rectangular bottom 30 or "palatre", bordered on its four sides by partitions extending at right angles on a low height, namely two longitudinal partitions 31 and 32, a rear wall 33 and an opposite front partition. 34 or "headrest".

Le palâtre 30 présente un axe longitudinal médian X-X'. The paddle 30 has a median longitudinal axis X-X '.

La têtière 34 présente dans sa partie centrale un évidement rectangulaire 341, au travers duquel l'extrémité du pêne 5 peut translater. Deux fentes 342, 343 sont ménagées de part et d'autre de l'évidement 341. Elles s'étendent parallèlement au rebord de la têtière 34. Leur rôle sera expliqué ultérieurement.The headrest 34 has in its central part a rectangular recess 341, through which the end of the bolt 5 can translate. Two slots 342, 343 are formed on either side of the recess 341. They extend parallel to the rim of the headrest 34. Their role will be explained later.

Le palâtre 30 est en outre percé d'une fente 300 et d'un orifice 301 en forme de haricot, qui sont alignés selon l'axe longitudinal X-X', l'orifice 301 étant plus proche de la têtière 34.The paddle 30 is further pierced by a slot 300 and a hole 301 in the form of a bean, which are aligned along the longitudinal axis X-X ', the orifice 301 being closer to the headrest 34.

Le palâtre 30 est également percé, par exemple à ses quatre coins, par des trous 302 qui permettent son assemblage avec le foncet 4.The paddle 30 is also pierced, for example at its four corners, by holes 302 which allow its assembly with the funcet 4.

Les cloisons longitudinales 31 et 32 sont percées, au voisinage de la cloison arrière 33, par un trou 311, respectivement 321, permettant la fixation du foncet 4, à l'aide de vis (visibles uniquement sur les figures 8 à 10), et à proximité de la têtière 34, par deux trous 312, 313, respectivement 322, 323.The longitudinal partitions 31 and 32 are pierced, in the vicinity of the rear wall 33, by a hole 311, respectively 321, allowing the fixation of the function 4, with the aid of screws (visible only on the Figures 8 to 10 ), and near the headrest 34, by two holes 312, 313, respectively 322, 323.

Les trous 312 et 322 sont coaxiaux et permettent le passage d'un élément (non représenté sur les figures) de fixation du demi-cylindre 6.The holes 312 and 322 are coaxial and allow the passage of an element (not shown in the figures) for fixing the half-cylinder 6.

Enfin, les trous 313 et 323, également coaxiaux, permettent le passage d'un axe de pivotement de la poignée 7 par rapport au coffre 3.Finally, the holes 313 and 323, also coaxial, allow the passage of a pivot axis of the handle 7 relative to the box 3.

Le foncet 4 va maintenant être décrit plus en détails en faisant référence à la figure 4.The feature 4 will now be described in more detail with reference to the figure 4 .

Il se compose d'une tôle de faible épaisseur de forme générale rectangulaire présentant deux bords longitudinaux 41, respectivement 42 et deux bords de plus petite longueur, à savoir un bord arrière 43 et un bord avant 44.It consists of a thin plate of generally rectangular shape having two longitudinal edges 41, respectively 42 and two edges of smaller length, namely a rear edge 43 and a front edge 44.

Le foncet 4 présente un axe longitudinal médian X1-X'1. The function 4 has a median longitudinal axis X1-X'1.

Le foncet 4 présente une encoche ou découpe 441, de forme rectangulaire qui débouche au niveau du bord avant 44. Le bord avant 44 est découpé de façon à présenter deux petites languettes 442 et 443, de part et d'autre de la découpe 441. Lorsque le foncet 4 est assemblé avec le coffre 3, ces languettes 442, 443 sont reçues respectivement dans les fentes 342 et 343 de la têtière 34. En outre, la découpe 441 se retrouve en regard de l'évidement 341.The function 4 has a notch or cut 441, of rectangular shape which opens at the front edge 44. The front edge 44 is cut so as to have two small tabs 442 and 443, on either side of the cut 441. When the function 4 is assembled with the trunk 3, these tabs 442, 443 are received respectively in the slots 342 and 343 of the headrest 34. In addition, the cut 441 is found opposite the recess 341.

Le foncet 4 présente également plusieurs trous 402, de préférence un dans chacun de ses quatre angles. Lorsque le foncet 4 est assemblé avec le coffre 3, ces trous 402 permettent le passage d'organes de fixation, tels que des vis (non représentées sur les figures). Ils sont placés en regard des trous 302 du coffre 3.The feature 4 also has a plurality of holes 402, preferably one in each of its four corners. When the function 4 is assembled with the trunk 3, these holes 402 allow the passage of fasteners, such as screws (not shown in the figures). They are placed opposite the holes 302 of the trunk 3.

La face 40 du palâtre 4 est dite "face interne", car elle est située en regard de l'intérieur du coffre 3, lorsque le palâtre 4 et ce coffre sont en position assemblée.The face 40 of the pallet 4 is called "internal face", because it is located opposite the inside of the trunk 3, when the pallet 4 and this chest are in the assembled position.

Les bords longitudinaux 41 et 42 du palâtre 4 sont munis au voisinage du bord arrière 43, d'une aile 410, respectivement 420, constituée par une portion de tôle de forme rectangulaire repliée à angle droit par rapport à la face interne 40. Ces deux ailes 410, 420 sont chacune percées d'un trou 411, respectivement 421.The longitudinal edges 41 and 42 of the pallet 4 are provided in the vicinity of the rear edge 43 of a wing 410, respectively 420, constituted by a rectangular portion of sheet metal folded at right angles to the internal face 40. These two wings 410, 420 are each pierced with a hole 411, respectively 421.

La distance entre les deux faces extérieures des ailes 410 et 420 est légèrement inférieure à la distance existant entre les faces intérieures des cloisons longitudinales 31 et 32 du coffre 3, de sorte que ces ailes 410, 420 peuvent être insérées à l'intérieur du coffre 3 lorsque ce dernier est assemblé avec le palâtre 4. Dans cette position d'assemblage, les trous 311, 411, 321 et 421 sont alignés et permettent l'assemblage à l'aide de deux vis 315, 325 visibles uniquement sur les figures 8 à 10 et d'écrous non représentés sur les figures.The distance between the two outer faces of the wings 410 and 420 is slightly less than the distance between the inner faces of the longitudinal partitions 31 and 32 of the trunk 3, so that the wings 410, 420 can be inserted inside the trunk 3 when the latter is assembled with the pallet 4. In this assembly position, the holes 311, 411, 321 and 421 are aligned and allow the assembly with two screws 315, 325 visible only on the Figures 8 to 10 and nuts not shown in the figures.

Le foncet 4 est percé d'une fente 400 et d'un orifice 401 en forme de haricot, alignés selon l'axe X1-X'1. Les orifices 301 et 401 sont coaxiaux lorsque le foncet 4 et le coffre 3 sont assemblés. Dans cette position, les axes X-X' et X1-X'1 sont parallèles.The function 4 is pierced with a slot 400 and a hole 401 in the form of a bean, aligned along the axis X1-X'1 . The orifices 301 and 401 are coaxial when the function 4 and the trunk 3 are assembled. In this position, the X-X ' and X1-X'1 axes are parallel.

Le foncet 4 présente une découpe en C entre les deux ailes 410 et 420, symétrique par rapport à l'axe X1-X'1. La tôle est repliée à angle droit par rapport à la face interne 40, de façon à définir une ouverture rectangulaire 403, bordée d'une patte 404 perpendiculaire au plan du foncet 4 et perpendiculaire aux ailes 410, 420. Son rôle sera décrit ultérieurement.The function 4 has a cutout in C between the two wings 410 and 420, symmetrical with respect to the axis X1-X'1. The sheet is bent at right angles to the inner face 40, so as to define a rectangular opening 403, bordered by a tab 404 perpendicular to the plane of the funcet 4 and perpendicular to the wings 410, 420. Its role will be described later.

Enfin, une entretoise 45 est rapportée par soudure sur la face interne 40 du foncet. Cette entretoise 45 est réalisée à partir d'une lamelle de tôle rectangulaire, repliée deux fois de façon à présenter une section en U à angles droits. Elle présente donc une zone centrale 450 et deux ailes latérales 451 et 452, percées chacune d'un trou 453, respectivement 454.Finally, a spacer 45 is attached by welding on the inner face 40 of the funcet. This spacer 45 is made from a plate of rectangular sheet folded twice to have a U-shaped section at right angles. It therefore has a central zone 450 and two lateral wings 451 and 452, each pierced with a hole 453, respectively 454.

Les deux ailes 451, 452 s'étendent de part et d'autre de la partie oblongue de l'orifice 401 en forme de haricot.The two wings 451, 452 extend on either side of the oblong portion of the hole 401 in the form of a bean.

L'entretoise 45 permet de maintenir une distance constante entre le coffre 3 et le foncet 4, lorsque ces deux éléments sont assemblés et sert également à la fixation du demi-cylindre 6 comme cela sera décrit ultérieurement.The spacer 45 makes it possible to maintain a constant distance between the trunk 3 and the trunk 4, when these two elements are assembled and is also used for fixing the half-cylinder 6 as will be described later.

Le pêne 5 va maintenant être décrit plus en détails en faisant référence aux figures 6 et 7.The bolt 5 will now be described in more detail with reference to Figures 6 and 7 .

Cette pièce a été obtenue à partir d'une tôle de forme sensiblement rectangulaire dont les côtés longitudinaux sont beaucoup plus longs que les côtés transversaux, cette plaque ayant été repliée longitudinalement deux fois, de façon à présenter une section transversale en forme de U à angles droits.This piece was obtained from a sheet of substantially rectangular shape whose longitudinal sides are much longer than the transverse sides, this plate having been folded longitudinally twice, so as to have a cross section in the shape of U angles rights.

Ce pêne 5 présente ainsi un fond 50 et deux côtés longitudinaux 51, 52.This bolt 5 thus has a bottom 50 and two longitudinal sides 51, 52.

Il présente un axe longitudinal X2-X'2. It has a longitudinal axis X2-X'2.

Le corps de pêne 5 est fermé à son extrémité arrière par une cloison arrière 53 qui s'étend perpendiculairement au fond 50 et aux deux côtés 51 et 52, et qui est légèrement en retrait par rapport aux extrémités libres arrières de ces côtés 51 et 52. Une colonnette cylindrique 530 est fixée, par exemple par vissage, perpendiculairement à cette cloison arrière 53, de façon à faire saillie vers l'extérieur du corps de pêne 5.The bolt body 5 is closed at its rear end by a rear wall 53 which extends perpendicularly to the bottom 50 and to both sides 51 and 52, and which is slightly set back relative to the rear free ends of these sides 51 and 52. A cylindrical pin 530 is fixed, for example by screwing, perpendicularly to this rear wall 53, so as to protrude outwardly from the bolt body 5.

L'extrémité avant 54 du corps de pêne 5 est de préférence inclinée en biseau, de façon à former un pêne connu de l'homme du métier sous l'appellation de "pêne demi-tour".The front end 54 of the bolt body 5 is preferably inclined, so as to form a bolt known to those skilled in the art under the name of "latch bolt".

Lorsque les différents éléments constitutifs du boitier de serrure 1 sont assemblés, le pêne demi-tour 54 fait saillie hors du boitier par l'évidement 341 de la têtière et se déplace lors de la fermeture de la porte pour s'engager automatiquement dans la gâche solidaire du chambranle de la porte, en assurant ainsi l'immobilisation de celle-ci.When the various components of the lock housing 1 are assembled, the latch bolt 54 protrudes out of the housing by the recess 341 of the headrest and moves when closing the door to engage automatically in the latch secured to the door jamb, thereby ensuring the immobilization of the door.

Ce pêne 54 pourrait également être un pêne dormant de section rectangulaire, mais qui ne permet pas d'assurer une fermeture automatique.This bolt 54 could also be a dead bolt of rectangular section, but which does not provide automatic closure.

Le fond 50 n'est pas plein sur la totalité de la longueur du corps de pêne 5. Il présente, dans sa partie centrale, sur environ un tiers de sa longueur, un évidement rectangulaire 55.The bottom 50 is not full over the entire length of the bolt body 5. It has, in its central part, about a third of its length, a rectangular recess 55.

La partie arrière du fond 50, qui s'étend depuis la cloison arrière 53, présente une fente longitudinale 58 qui débouche dans l'évidement 55.The rear portion of the bottom 50, which extends from the rear wall 53, has a longitudinal slot 58 which opens into the recess 55.

Enfin, les côtés longitudinaux 51 et 52 du corps de pêne 5 sont percés d'un trou 511, respectivement 521, et d'une ouverture 512, respectivement 522.Finally, the longitudinal sides 51 and 52 of the bolt body 5 are pierced with a hole 511, respectively 521, and an opening 512, respectively 522.

Les trous 511 et 521 sont circulaires, coaxiaux et perpendiculaires à l'axe X2-X'2. The holes 511 and 521 are circular, coaxial and perpendicular to the axis X2-X'2.

Les ouvertures 512 et 522 sont également coaxiales et symétriques par rapport à l'axe X2-X'2. Elles présentent une portion carrée qui se prolonge en direction du demi-pêne 54 par une portion de forme oblongue.The openings 512 and 522 are also coaxial and symmetrical with respect to the axis X2-X'2 . They have a square portion which extends in the direction of the half-bolt 54 by a portion of oblong shape.

Comme on peut le voir sur les figures 8 à 10, les orifices 511 et 521 permettent la fixation d'un tourillon 56, qui s'étend perpendiculairement à l'axe longitudinal X2-X'2 du corps de pêne 5.As can be seen on the Figures 8 to 10 , the orifices 511 and 521 allow the attachment of a pin 56, which extends perpendicularly to the longitudinal axis X2-X'2 of the bolt body 5.

Par ailleurs, lorsque le corps de pêne 5 est introduit dans le coffre 3, un ressort 57, par exemple un ressort hélicoïdal, dit "ressort de pêne", est monté et maintenu entre le côté arrière 33 du coffre 3 et la colonnette 530 autour de laquelle il est fixé. Ce ressort 57 est visible uniquement sur les figures 1 et 8. Il tend en permanence à déplacer le corps de pêne 5 dans la position dite "active" où le demi-pêne 54 est hors du coffre 3, comme représenté sur la figure 8. Dans cette position, la face de la cloison arrière 53 opposée à celle portant la colonnette 530 vient en appui contre la patte 404.Furthermore, when the bolt body 5 is introduced into the trunk 3, a spring 57, for example a helical spring, called "bolt spring" is mounted and held between the rear side 33 of the trunk 3 and the column 530 around of which he is fixed. This spring 57 is visible only on the figures 1 and 8 . It constantly tends to move the bolt body 5 in the so-called "active" position where the half-bolt 54 is outside the box 3, as shown in FIG. figure 8 . In this position, the face of the rear wall 53 opposite to that carrying the column 530 abuts against the tab 404.

Enfin, les côtés 51 et 52 présentent à proximité de l'extrémité avant 54 (demi-pêne) un décrochement 513, respectivement 523. Lorsque le corps de pêne 5 est monté dans le boitier, l'encoche 441 du foncet 4 sert à le guider et sert également de butée arrière de fin de course du corps de pêne 5. Les décrochements 513, 523 viennent en butée contre le fond de l'encoche 441.Finally, the sides 51 and 52 have near the front end 54 (half-bolt) a recess 513, respectively 523. When the bolt body 5 is mounted in the housing, the notch 441 of the funcet 4 serves to guide and also serves as back limit stop of the bolt body 5. The recesses 513, 523 abut against the bottom of the notch 441.

Le boitier de serrure conforme à l'invention est équipé d'un dispositif 6, connu de l'homme du métier sous l'appellation de "demi-cylindre européen", et qui permet grâce à une clé de déplacer axialement le demi-pêne 54 afin de l'extraire de la gâche et d'ouvrir la porte.The lock housing according to the invention is equipped with a device 6, known to those skilled in the art under the name of "European half-cylinder", and which makes it possible, thanks to a key, to axially move the half-bolt 54 to extract it from the strike and open the door.

L'appellation "européenne" correspond à un cylindre en forme de haricot. L'appellation "demi-cylindre" désigne le fait que la serrure ne peut être actionnée que d'un seul côté de la porte, ici du côté extérieur de celle-ci.The name "European" corresponds to a cylinder shaped bean. The term "half-cylinder" refers to the fact that the lock can be operated only on one side of the door, here on the outer side thereof.

Le demi-cylindre 6 est monté à l'intérieur du boitier 3 de façon à traverser l'orifice 401 du foncet 4, l'évidement 55 du corps de pêne 5 et enfin à affleurer au niveau de l'orifice en forme de haricot 301 du coffre 3.The half-cylinder 6 is mounted inside the housing 3 so as to pass through the orifice 401 of the funcet 4, the recess 55 of the bolt body 5 and finally to be flush with the bean-shaped orifice 301. of the safe 3.

Il est maintenu en position à l'aide d'une vis (non représentée sur les figures) montée de façon soit à traverser le trou 322, la partie oblongue de l'orifice 522, le trou 454 de l'entretoise 45 du foncet et à pénétrer à la base du demi-cylindre 6, soit à traverser le trou 312, la partie oblongue de l'orifice 512, le trou 453 et à pénétrer à la base du demi-cylindre 6.It is held in position by means of a screw (not shown in the figures) mounted so as to pass through the hole 322, the oblong portion of the orifice 522, the hole 454 of the spacer 45 of the funcet and to penetrate the base of the half-cylinder 6, or to cross the hole 312, the oblong portion of the orifice 512, the hole 453 and to penetrate the base of the half-cylinder 6.

Le demi-cylindre européen 6 présente un orifice 61 d'insertion de la clé, qui permet d'entraîner la rotation d'un rotor 62 à l'intérieur d'un stator non visible sur les figures. La rotation de ce rotor 62 provoque, de façon connue de l'homme du métier, le déplacement d'un doigt d'entraînement 63 ou "panneton".The European half-cylinder 6 has an opening 61 for inserting the key, which makes it possible to drive the rotation of a rotor 62 inside a stator that is not visible in the figures. The rotation of this rotor 62 causes, in a manner known to those skilled in the art, the movement of a driving finger 63 or "bit".

Le demi-cylindre 6 est disposé à l'intérieur du corps de pêne 5 de façon que la rotation de la clé entraîne le positionnement du panneton 63 à l'intérieur de la partie carrée de l'ouverture 512 ou de l'ouverture 522 en fonction du sens de rotation de la clé, et de ce fait, lorsque la rotation se poursuit, le déplacement vers l'arrière du corps de pêne 5, à l'encontre de la force exercée par le ressort 57, jusqu'à amener le demi-pêne 54 en retrait, dans la position passive représentée sur la figure 9. Ce déplacement axial s'effectue selon l'axe X2-X'2. The half-cylinder 6 is disposed inside the bolt body 5 so that the rotation of the key causes the bit 63 to be positioned within the square portion of the opening 512 or the opening 522. according to the direction of rotation of the key, and therefore, when the rotation continues, the rearward movement of the bolt body 5, against the force exerted by the spring 57, to bring the half-bolt 54 recessed, in the passive position shown on the figure 9 . This axial displacement is performed along the axis X2-X'2.

On notera que les portions oblongues des ouvertures 512 et 522 permettent le déplacement axial du corps de pêne 5 malgré la présence des vis de fixation du demi-cylindre 6.It will be noted that the oblong portions of the openings 512 and 522 enable the bolt body 5 to be axially displaced despite the presence of the fixing screws of the half-cylinder 6.

Inversement, la rotation de la clé dans l'autre sens permet de ramener le panneton dans l'alignement de l'axe X2-X'2, le ressort 57 agissant alors de nouveau pour déplacer le pêne 5 dans la position active de verrouillage de la porte.Conversely, the rotation of the key in the other direction makes it possible to return the bit in alignment with the axis X2-X'2, the spring 57 then acting again to move the bolt 5 in the active locking position of the door.

Le boitier de serrure 1 conforme à l'invention est également équipé d'un plastron anti-panique 2 dont la structure et le fonctionnement vont maintenant être expliqués plus en détails.The lock housing 1 according to the invention is also equipped with an anti-panic plastron 2 whose structure and operation will now be explained in more detail.

La poignée de plastron 7 va maintenant être décrite en faisant référence à la figure 2.The plastron handle 7 will now be described with reference to the figure 2 .

Cette poignée comprend une portion centrale 70, de forme rectangulaire et sur environ la moitié de sa longueur deux ailes latérales triangulaires 71, 72 qui s'étendent perpendiculairement à ladite portion centrale 70.This handle comprises a central portion 70, of rectangular shape and on about half its length two triangular lateral wings 71, 72 which extend perpendicularly to said central portion 70.

La portion centrale 70 présente plusieurs trous de fixation 700, de préférence un à chacun de ses quatre angles, et dans sa partie médiane, deux trous plus rapprochés 701.The central portion 70 has a plurality of attachment holes 700, preferably one at each of its four corners, and in its middle portion two nearer holes 701.

En outre, la tôle constituant la poignée 7 a été découpée dans la zone centrale de cette poignée, selon une découpe en C, et la tôle a été pliée, de façon à former un évidement rectangulaire 703 et une languette 702 qui s'étend dans un plan parallèle aux ailes 71 et 72.In addition, the sheet forming the handle 7 has been cut in the central zone of this handle, in a C-cut, and the sheet has been folded, so as to form a rectangular recess 703 and a tongue 702 which extends into a plane parallel to the wings 71 and 72.

La pointe inférieure du triangle de chaque aile 71, 72 est également percée d'un trou 710, respectivement 720.The lower tip of the triangle of each wing 71, 72 is also pierced with a hole 710, respectively 720.

Le bord incliné du triangle de chaque aile 71, 72 présente de préférence une échancrure en forme de demi-cercle référencé 711, respectivement 721, ces échancrures facilitant le passage des vis d'assemblage du demi-cylindre 6 et du coffre 3.The inclined edge of the triangle of each wing 71, 72 preferably has a semicircular notch referenced 711, respectively 721, these notches facilitating the passage of the assembly screws of the half-cylinder 6 and the trunk 3.

Comme on peut le voir sur la figure 1, le poussoir 8 est formé à partir d'une tôle de forme sensiblement rectangulaire beaucoup plus longue que large. Cette tôle est repliée le long de ses deux bords longitudinaux, de sorte qu'elle présente une portion centrale 80 et deux ailes latérales 81 et 82 de faible hauteur.As can be seen on the figure 1 , the pusher 8 is formed from a sheet of substantially rectangular shape much longer than large. This sheet is folded along its two longitudinal edges, so that it has a central portion 80 and two side wings 81 and 82 of low height.

Elle est percée à son extrémité avant par des trous 800, de préférence au nombre de quatre, disposés aux quatre coins d'un rectangle, de façon à être situés en regard des orifices 700 de la poignée 7, lorsque ces deux éléments sont assemblés. Cet assemblage est effectué par exemple à l'aide de vis 801 et d'écrous non représentés sur les figures.It is pierced at its front end by holes 800, preferably four in number, arranged at the four corners of a rectangle, so as to be located opposite the orifices 700 of the handle 7, when these two elements are assembled. This assembly is performed for example using screws 801 and nuts not shown in the figures.

La pièce en L 9 présente deux ailes 90 et 91 qui sont perpendiculaires l'un à l'autre. L'aile 90 présente une forme rectangulaire et est percée de deux trous 900. Ces trous sont espacés de la même distance que les trous 701 de la poignée 7.The piece L 9 has two wings 90 and 91 which are perpendicular to each other. The wing 90 has a rectangular shape and is pierced with two holes 900. These holes are spaced from the same distance as the holes 701 of the handle 7.

La pièce en L 9 est montée sur la poignée 7, de façon que l'aile 90 vienne au contact de la face intérieure de la poignée 7 et que les trous 900 soient alignés avec les trous 701. Les deux pièces sont ainsi assemblées par des rivets passant au travers de ces deux orifices. Une fois assemblée, l'aile 91 s'étend donc perpendiculairement au plan de la portion centrale 70 de la poignée 7.The L-shaped part 9 is mounted on the handle 7, so that the flange 90 comes into contact with the inner face of the handle 7 and the holes 900 are aligned with the holes 701. The two parts are thus assembled by rivets passing through these two orifices. Once assembled, the wing 91 therefore extends perpendicular to the plane of the central portion 70 of the handle 7.

L'aile 91 présente une zone 910 sensiblement rectangulaire contigüe à l'aile 90, qui se prolonge par une zone 911 en forme de triangle isocèle dont l'un des deux côtés égaux se situe dans le prolongement de la zone rectangulaire 910. La zone triangulaire 911 se prolonge par un crochet 912.The wing 91 has a substantially rectangular zone 910 contiguous to the wing 90, which is extended by an area 911 in the form of an isosceles triangle whose one of the two equal sides is in the extension of the rectangular zone 910. The zone triangular 911 is extended by a hook 912.

Le flanc de la base du triangle isocèle 911 constitue une rampe inclinée 913.The flank of the base of the isosceles triangle 911 constitutes an inclined ramp 913.

Le flanc 914 du crochet 912 qui se situe dans le prolongement de la rampe inclinée 913 constitue une butée d'arrêt.The side 914 of the hook 912 which lies in the extension of the inclined ramp 913 is a stop.

La rampe inclinée 913 et le flanc 914 formant butée sont espacés d'un angle α d'une valeur comprise entre 125 et 140°, de préférence voisine de 135°.The inclined ramp 913 and the flank 914 forming an abutment are spaced from an angle α of a value between 125 and 140 °, preferably close to 135 °.

Le plastron 2 est monté sur le coffre 3, de façon à pouvoir pivoter angulairement autour d'un axe matérialisé uniquement sur les figures 8 à 10 par le pointillé Y-Y' et qui passe au travers des trous 710, 313, 323 et 720. Ce montage pivotant peut être assuré par des vis et écrous, par exemple.The plastron 2 is mounted on the trunk 3, so as to be pivotable angularly about an axis materialized only on the Figures 8 to 10 by the dotted Y-Y ' and which passes through the holes 710, 313, 323 and 720. This pivoting assembly can be provided by screws and nuts, for example.

En outre, un ressort 73 dit "ressort de plastron" (par exemple un ressort hélicoïdal) est positionné entre la poignée 7 et le coffre 3 de façon que l'une de ses extrémités soit fixée sur la languette 702 et que l'autre soit reçue à l'arrière de la fente 300, cette dernière autorisant également le passage de la pièce en L 9. Ce ressort 73 tend en permanence à écarter la poignée et donc le poussoir 8, du coffre 3.In addition, a spring 73 called "plastron spring" (for example a helical spring) is positioned between the handle 7 and the trunk 3 so that one of its ends is fixed on the tongue 702 and the other is received at the rear of the slot 300, the latter also allowing the passage of the L-shaped part 9. This spring 73 constantly tends to move the handle and therefore the pusher 8, the trunk 3.

En outre, une fois le plastron 2 et le boitier 1 assemblés et au repos, l'axe 56 se loge à l'intersection entre la butée 914 et la rampe inclinée 913 (voir figure 8). La fente 58 permet le passage de l'aile 91.In addition, once the plastron 2 and the housing 1 assembled and at rest, the axis 56 is housed at the intersection between the stop 914 and the inclined ramp 913 (see figure 8 ). The slot 58 allows the passage of the wing 91.

L'axe de pivotement Y-Y' est perpendiculaire aux axes X-X', X1-X'1 1 et X2-X'2. The pivot axis Y-Y ' is perpendicular to the axes X-X' , X1-X'1 1 and X2-X'2.

Lorsque l'opérateur ne peut utiliser la clé (par exemple parce qu'il est blessé), il appuie avec son corps sur le poussoir 8, à l'encontre de la force exercée par le ressort 73, ce qui a pour effet de faire pivoter la pièce en L 9. La rampe inclinée 913 appuie de ce fait sur le tourillon 56 et déplace celui-ci vers l'arrière, à l'encontre de la force exercée par le ressort 57, jusqu'à amener le corps de pêne 5 dans la position passive représentée sur la figure 10. Dans cette position, le demi-pêne 54 est en position rétractée et la porte peut s'ouvrir. Le mouvement inverse s'effectue dès que l'opérateur relâche la pression sur le plastron 2 et le corps de pêne revient en position active représentée sur la figure 8.When the operator can not use the key (for example because he is injured), he presses with his body on the pusher 8, against the force exerted by the spring 73, which has the effect of pivoting the L-shaped piece 9. The inclined ramp 913 thereby presses on the pin 56 and moves the latter 56 towards the rear, against the force exerted by the spring 57, to bring the bolt body 5 in the passive position shown on the figure 10 . In this position, the half-bolt 54 is in the retracted position and the door can open. The reverse movement is effected as soon as the operator releases the pressure on the plastron 2 and the bolt body returns to the active position represented on the figure 8 .

Le dispositif conforme à l'invention permet d'utiliser un demi-cylindre européen plus communément répandu et facile à remplacer en cas de perte de la clé. En outre, ce demi-cylindre étant symétrique par rapport au boitier 1, le dispositif conforme à l'invention peut être monté indifféremment sur une porte ouvrant à droite ou à gauche. Ceci permet d'optimiser la production et de réduire les coûts puisqu'un seul modèle est fabriqué.The device according to the invention makes it possible to use a European half-cylinder that is more commonly used and easy to replace if the key is lost. In addition, this half-cylinder being symmetrical with respect to the housing 1, the device according to the invention can be mounted indifferently on a door opening to the right or left. This optimizes production and reduces costs as only one model is manufactured.

Enfin, la position centrée de la rampe inclinée 913 et du tourillon 56 par rapport au corps de pêne 5 garantit une répartition homogène des efforts.Finally, the centered position of the inclined ramp 913 and the pin 56 relative to the bolt body 5 ensures a uniform distribution of forces.
