Description

La présente invention concerne un dispositif de verrouillage pour vantaux de portails ou de portes à deux battants.The present invention relates to a locking device for leaves double gates or doors.

Qu'il s'agisse de portes à deux battants installées dans l'ouverture d'entrée de locaux ou de portails à deux vantaux installés entre deux piliers délimitant l'ouverture d'entrée d'une clôture, le vantail qui s'ouvre en second de ces portes ou portails est généralement équipé d'un verrou, au moins en partie basse. Ce verrou, qu'ils soit de type "à boite" ou "à baïonnette" comprend une tige méplate ou demi-ronde disposée verticalement, avec une aptitude de translation axiale, et dont l'une des extrémités est munie d'une poignée ou bouton de manoeuvre. L'extrémité opposée de cette tige est destinée à s'engager dans une gâche installée dans le seuil de l'ouverture pour condamner le vantail muni du verrou.Whether double doors installed in the opening entrance to rooms or gates with two leaves installed between two pillars delimiting the entry opening of a fence, the leaf which opens second from these doors or gates is generally fitted with a lock, at least in part low. This lock, whether of the "box" or "bayonet" type, includes a flat or half-round rod arranged vertically, with a capacity of axial translation, and one end of which is provided with a handle or operating button. The opposite end of this rod is intended to engage in a keeper installed in the threshold of the opening to lock the leaf fitted with the lock.

Ce type de verrou présente au moins deux sortes d'inconvénients :

  • des inconvénients dans l'utilisation : la manoeuvre de la tige s'effectue dans une position penchée ou courbée inconfortable, la traction de cette tige nécessite un effort plus ou moins important suivant qu'elle se trouve ou non coincée dans la gâche, tandis que son enfoncement dans ladite gâche qui nécessite l'alignement des axes de la tige et de la gâche, n'est pas toujours obtenu au premier essai ;
  • des inconvénients dans l'efficacité de la fermeture : lorsque le portail ou la porte est à claire-voie, il est possible de soulever la tige à partir de l'extérieur et d'ouvrir le portail ou la porte en repoussant ou en tirant simultanément les deux vantaux.
This type of lock has at least two kinds of drawbacks:
  • disadvantages in use: the rod is operated in an uncomfortable bent or bent position, the pulling of this rod requires a greater or lesser force depending on whether or not it is trapped in the keeper, while its insertion into said keeper which requires the alignment of the axes of the rod and the keeper, is not always obtained on the first try;
  • drawbacks in the efficiency of the closing: when the gate or door is open, it is possible to lift the rod from the outside and open the gate or door by pushing or pulling simultaneously the two leaves.

Pour pallier à ces inconvénients, il est proposé, selon le document FR-A-2.624.183, un dispositif de verrouillage pour vantaux de porte à deux battants, comprenant un loquet basculant solidaire d'un axe vertical de pivotement, comportant une première partie rectiligne rigidement solidaire de l'axe vertical de basculement et une deuxième partie formant un angle droit avec ladite deuxième partie, cette deuxième partie constituant un organe de blocage qui, dans la position de verrouillage, se place devant le bord inférieur de l'un des vantaux et s'oppose au pivotement d'ouverture de celui-ci.To overcome these drawbacks, it is proposed, according to the document FR-A-2.624.183, a locking device for door leaves with two leaves, comprising a tilting latch secured to a vertical axis of pivoting, comprising a first rectilinear part rigidly integral with the vertical tilt axis and a second part forming a right angle with said second part, this second part constituting an organ for blocking which, in the locked position, is placed in front of the lower edge of one of the leaves and opposes the opening pivoting thereof.

La présente invention a notamment pour but de remédier à ces inconvénients, de manière alternative.The object of the present invention is in particular to remedy these disadvantages, alternatively.

Selon l'invention, cet objectif est atteint grâce à un dispositif de verrouillage comprenant un loquet basculant solidaire d'un axe vertical de pivotement, ce loquet basculant comprenant une première partie rectiligne rigidement solidaire de l'axe vertical de basculement et une deuxième partie formant un angle droit avec ladite première partie, ce dispositif de verrouillage étant remarquable en ce que ledit axe vertical de pivotement est logé dans une lumière que présente un coffre ou bloc destiné à être installé fixement dans le seuil d'une ouverture et comportant une face avant plane pour l'appui du bord inférieur des vantaux d'une porte, et en ce que la lumière dans laquelle est logé avec une aptitude de déplacement, l'axe vertical de pivotement du loquet basculant, a une forme oblongue et une orientation oblique par rapport à ladite face avant plane du bloc ou coffre.According to the invention, this objective is achieved thanks to a device for lock comprising a tilting latch secured to a vertical axis of pivoting, this tilting latch comprising a first straight part rigidly secured to the vertical tilting axis and a second part forming a right angle with said first part, this locking device being remarkable in that said vertical pivot axis is housed in a light presented by a box or block intended to be fixedly installed in the threshold of an opening and having a flat front face for supporting the edge lower leaves of a door, and in that the light in which is housed with the ability to move, the vertical pivot axis of the tilting latch has an oblong shape and an oblique orientation relative to said flat front face of the block or trunk.

Selon une disposition particulière de l'invention, le loquet basculant comporte un talon rigidement solidaire de l'axe de pivotement dudit loquet et formant un angle, de préférence de 90° par rapport à la première partie de ce dernier.According to a particular arrangement of the invention, the tilting latch has a heel rigidly secured to the pivot axis of said latch and forming an angle, preferably 90 ° from the first part of the latter.

Grâce au dispositif de verrouillage comportant les dispositions caractéristiques susmentionnées, il est possible d'ouvrir le second vantail du portail, après ouverture de l'ouvrant, sans aucune manoeuvre, le pivotement dudit second vantail assurant l'effacement automatique du loquet basculant. D'autre part, la condamnation du second vantail se trouve automatiquement assurée lors de la fermeture de l'ouvrant ; en effet, dans un premier temps, la fermeture du second ventail assure un pré-positionnement du loquet qui est ensuite basculé en position de verrouillage sous la poussée de l'ouvrant.Thanks to the locking device comprising the provisions above features, it is possible to open the second leaf of the gate, after opening the sash, without any operation, pivoting said second leaf ensuring automatic erasure of the tilting latch. On the other hand, the condemnation of the second leaf is found automatically ensured when the opening is closed; indeed, at first, the closing the second wing ensures pre-positioning of the latch which is then tilted to the locked position under the thrust of the opening.

Le dispositif de verrouillage selon l'invention procure une meilleure sécurité de la fermeture. En effet, il est impossible de déplacer le loquet, sans l'ouverture préalable de l'ouvrant. Autrement dit, on ne peut déverrouiller le dispositif et ouvrir le portail ou la porte en poussant ou en tirant simultanément les deux vantaux, si la ou les serrures n'a pas ou n'ont pas été ouverte(s).The locking device according to the invention provides better closing security. Indeed, it is impossible to move the latch, without the opening of the opening. In other words, you cannot unlock the device and open the gate or door by pushing or pulling simultaneously the two leaves, if the lock (s) has not been or have not been opened.

Un autre avantage de ce dispositif est qu'il ne nécessite aucune intervention (soudure, perçage, ...) sur les vantaux de la porte. En outre, en cas de mise hors d'usage, il peut être facilement remplacé, sans avoir obligatoirement recours à un spécialiste.Another advantage of this device is that it does not require any intervention (welding, drilling, ...) on the door leaves. Furthermore, in in the event of decommissioning, it can be easily replaced without having obligatorily recourse to a specialist.

    • On se reporte auxdits dessins pour décrire un mode d'exécution avantageux, quoique non limitatif, du dispositif de verrouillage selon l'invention. Reference is made to said drawings to describe an embodiment. advantageous, although not limiting, of the locking device according to the invention.

    Dans la suite du présent exposé, et dans les revendications, le terme "porte" sera utilisé pour désigner aussi bien une porte à deux battants équipant l'entrée d'un local, qu'un portail à deux vantaux installé dans l'ouverture d'entrée d'une clôture.In the remainder of this disclosure, and in the claims, the term "door" will be used to designate a double door equipping the entrance to a room, that a gate with two leaves installed in the opening entrance to a fence.

    Ce dispositif comprend un coffre ou boítier 1 qui peut être fixé sur une semelle 2 agencée ou conformée pour permettre son installation, à demeure, à l'aide de tous moyens et procédés de fixation appropriés, dans le seuil d'une ouverture équipée d'une porte à deux vantaux.This device comprises a chest or case 1 which can be fixed on a sole 2 arranged or shaped to allow its permanent installation at using all appropriate means and methods of fixation, within the threshold of opening equipped with a door with two leaves.

    Ce coffre présente une face avant plane 3 destinée à l'appui du bord inférieur des vantaux de la porte, dans la positon de fermeture de celle-ci.This box has a flat front face 3 intended to support the edge lower of the door leaves, in the closing position of the latter.

    Dans le coffre 1, est implanté un loquet basculant 4 rigidement solidaire d'un axe 5 logé, verticalement, dans ledit coffre. Cet axe vertical est monté avec une aptitude de translation latérale, par l'intermédiaire de ses extrémités, dans des lumières 6 que présentent, en correspondance, les parois horizontales supérieure 7 et inférieure 8, respectivement, du coffre 1.In the trunk 1, there is a tilting latch 4 rigidly secured an axis 5 housed vertically in said trunk. This vertical axis is mounted with lateral translational ability, through its ends, in lights 6 which the walls present in correspondence horizontal upper 7 and lower 8, respectively, of the trunk 1.

    Les lumières oblongues 6 ont une orientation oblique par rapport à la face verticale avant 3 du coffre 1. Le grand axe de ces lumières forme, de préférence, un angle α de 45° avec le plan dans lequel est comprise ladite face avant 3.The oblong lights 6 have an oblique orientation relative to the front vertical face 3 of the trunk 1. The major axis of these lights forms, preferably an angle α of 45 ° with the plane in which said range is included front 3.

    De manière avantageuse, le loquet basculant 4 est constitué par un robuste fer plat plié, d'une largeur de quelques centimètres, par exemple de l'ordre de 3 cm. Il comporte une première partie rectiligne 4a rigidement solidaire, par exemple par soudure, de l'axe 5, une deuxième partie 4b formant un angle droit avec ladite première partie 4a, et, de préférence, une troisième partie 4c formant un angle, par exemple de l'ordre de 90°, avec ladite deuxième partie 4b. La première partie 4a et la troisième partie 4c sont ainsi disposées dans des plans parallèles ou sensiblement parallèles.Advantageously, the tilting latch 4 is constituted by a sturdy folded flat iron, a few centimeters wide, for example around 3 cm. It comprises a first rectilinear part 4a rigidly secured, for example by welding, to the axis 5, a second part 4b forming a right angle with said first part 4a, and preferably a third part 4c forming an angle, for example of the order of 90 °, with said second part 4b. The first part 4a and the third part 4c are thus arranged in parallel or substantially parallel planes.

    La première partie 4a est destinée à s'insérer entre les chants des deux vantaux, la deuxième partie 4b a pour fonction de retenir le deuxième vantail, et la troisième partie 4c qui n'est pas indispensable au fonctionnement du dispositif, est destinée à faciliter la manoeuvre du loquet, à l'aide du pied, en cas de besoin.The first part 4a is intended to be inserted between the songs of the two leaves, the second part 4b has the function of retaining the second leaf, and the third part 4c which is not essential for the functioning of the device, is intended to facilitate the operation of the latch, using the foot, when needed.

    La première partie 4a et la deuxième partie 4b sont avantageusement raccordées, extérieurement, par une surface courbe 4d.The first part 4a and the second part 4b are advantageously externally connected by a curved surface 4d.

    Le loquet 4 ainsi conformé émerge du coffre ou boítier 1, par une large ouverture 9 ménagée dans la face avant 3 de ce dernier et dans laquelle peut se déplacer la première partie 4a dudit loquet.The latch 4 thus formed emerges from the trunk or case 1, by a wide opening 9 formed in the front face 3 of the latter and in which can move the first part 4a of said latch.

    Le loquet comporte encore avantageusement un talon 10 rigidement solidaire de l'axe de pivotement 5 et formant un angle, de préférence de l'ordre de 90°, par rapport à la première partie 4a dudit loquet.The latch also advantageously comprises a heel 10 rigidly integral with the pivot axis 5 and forming an angle, preferably of the order 90 °, relative to the first part 4a of said latch.

    Le talon 10 est ainsi orienté parallèlement ou sensiblement parallèlement à la deuxième partie 4b du loquet 4.The heel 10 is thus oriented parallel or substantially parallel to the second part 4b of the latch 4.

    L'extrémité antérieure 6a de la lumière oblongue 6 est disposée à proximité de l'un des bords verticaux 9a de l'ouverture frontale 9, de sorte que ledit bord forme butée limitant l'amplitude du pivotement du loquet basculant 4 dans la position d'ouverture. Grâce à cette disposition, le talon 10 reste placé dans une position permettant son pivotement sous la poussée du second vantail B2 lors de la fermeture de celui-ci (figure 8).The anterior end 6a of the oblong lumen 6 is disposed at proximity of one of the vertical edges 9a of the front opening 9, so that said edge forms a stop limiting the amplitude of the pivoting of the tilting latch 4 in the open position. Thanks to this arrangement, the heel 10 remains placed in a position allowing it to pivot under the push of the second leaf B2 when it is closed (figure 8).

    L'extrémité supérieure de l'axe de pivotement vertical 5 du loquet basculant 4 est munie d'une tête 5a. Pour ne pas gêner la translation de l'axe 5, l'extrémité inférieure de celui-ci est logée, avec une aptitude de déplacement, dans un petit carter 11 fixé, par soudure ou autrement, sous la semelle de fixation 2 (figure 2).The upper end of the vertical pivot axis 5 of the latch tilting 4 is provided with a head 5a. In order not to hinder the translation of the axis 5, the lower end thereof is housed, with an ability to displacement, in a small casing 11 fixed, by welding or otherwise, under the fixing plate 2 (figure 2).

    Naturellement, les dimensions du dispositif de verrouillage selon l'invention et de son loquet basculant 4-5 peuvent être adaptées aux dimensions des portes à deux vantaux à la fermeture desquelles ils sont destinés. Naturally, the dimensions of the locking device according to the invention and its tilting latch 4-5 can be adapted to dimensions of double leaf doors at the closing of which they are intended.

    Les figures 6 à 10 illustrent le fonctionnement du dispositif de verrouillage selon l'invention.Figures 6 to 10 illustrate the operation of the locking according to the invention.

    La figure 6 montre la porte fermée, par exemple, par l'intermédiaire de la serrure (non représentée) équipant ses deux battants B1 et B2. Dans cette position, la partie 4a du loquet est calée entre les chants adjacents des deux vantaux, sa partie 4b recouvre le bord du second vantail B2, sa partie 4c forme une saillie orientée vers l'avant, l'axe 5 se trouve dans la portion médiane de la lumière 6. Dans cette situation, il est impossible de basculer le loquet 4, sans ouverture de la serrure et de l'ouvrant B1.Figure 6 shows the door closed, for example, through the lock (not shown) equipping its two leaves B1 and B2. In this position, part 4a of the latch is wedged between the adjacent edges of the two leaves, its part 4b covers the edge of the second leaf B2, its part 4c forms a projection facing forward, axis 5 is located in the middle portion of the light 6. In this situation, it is impossible to tilt the latch 4, without opening the lock and opening B1.

    La figure 7 montre l'ouverture de l'ouvrant B1 laquelle n'a aucune influence sur la position du loquet dont le basculement en direction du centre de l'ouverture est toutefois autorisé.Figure 7 shows the opening of the opening B1 which has no influence on the position of the latch, the tilting towards the center opening is allowed.

    La figure 8 illustre l'ouverture du second vantail B2 laquelle entraíne automatiquement le basculement et le déverrouillage du loquet 4, sous la poussée dudit vantail, sans qu'il soit besoin d'intervenir manuellement sur le dispositif de verrouillage. Conjointement, l'axe 5 se trouve rapproché de l'extrémité antérieure de la lumière oblongue 6.Figure 8 illustrates the opening of the second leaf B2 which drives automatically tilting and unlocking the latch 4, under the thrust of said leaf, without the need to manually intervene on the locking device. Jointly, axis 5 is close to the anterior end of the oblong lumen 6.

    Les figures 9 et 10 montrent les deux phases successives de basculement du loquet 4 dans la positon de verrouillage. Dans un premier temps, lors de sa fermeture, le second vantail repousse le talon 10 en direction de l'intérieur du coffre 1, ce qui entraíne le pivotement du loquet dont la partie d'arrêt 4b se trouve rapprochée du bord du second vantail B2 (figure 9). Dans un deuxième temps, lors de sa fermeture, le bord de l'ouvrant B1 glisse sur la surface courbe 4d du loquet (figure 10) en assurant le pivotement complémentaire du loquet en position de verrouillage (figure 6). Lors de ces deux mouvements de basculement du loquet 4, l'axe de pivotement 5 de ce dernier se trouve successivement déplacé en direction de la partie médiane de la lumière 6.Figures 9 and 10 show the two successive phases of tilting of the latch 4 in the locking position. Initially time, when it closes, the second leaf pushes the heel 10 towards from the inside of the trunk 1, which causes the latch to pivot, the part of which stop 4b is located near the edge of the second leaf B2 (Figure 9). In a second time, when it is closed, the edge of the opening B1 slides on the 4d curved surface of the latch (Figure 10) ensuring the pivoting complementary to the latch in the locked position (figure 6). During these two tilting movements of the latch 4, the pivot axis 5 of this last one is successively moved towards the middle part of light 6.
