Description

La présente invention concerne les serrures et se rapporte plus particulièrement à une serrure dont la poignée d'actionnement doit pouvoir être tournée librement dans le sens inverse au sens d'actionnement normal du pène de la serrure.The present invention relates to locks and relates more particularly to a lock whose actuating handle must be able to be freely rotated in the opposite direction to the normal actuation direction of the bolt of the lock.

Les poignées de portes, fenêtres ou autres vantaux sont reliées aux serrures par une tige de manoeuvre rigide généralement de section carrée, dont une des extrémités est engagée dans une poignée située sur une des faces du vantail et dont l'autre extrémité est engagée soit dans le fouillot de la serrure, soit après avoir traversé celui-ci de part en part, dans une seconde poignée située sur l'autre face du vantail.The handles of doors, windows or other leaves are connected to the locks by a rigid operating rod generally of square section, one end of which is engaged in a handle located on one of the faces of the leaf and the other end of which is engaged either in the lock follower, either after crossing it right through, in a second handle located on the other side of the leaf.

Certains vantaux comportent un cadre ouvrant ou un panneau amovible formant volet dont la pose et la dépose nécessitent le démontage préalable de la poignée se trouvant sur la face du vantail sur laquelle est monté le cadre ou le panneau.Some leaves have an opening frame or a removable panel forming a shutter, the installation and removal of which require the prior removal of the handle located on the face of the leaf on which the frame or the panel is mounted.

Cet inconvénient est particulièrement ressenti lorsque la poignée est constituée par une béquille qui, en position de repos, s'étend perpendiculairement au chant du vantail et gêne par conséquent la manoeuvre du cadre ou du panneau.This drawback is particularly felt when the handle is constituted by a stand which, in the rest position, extends perpendicularly to the edge of the leaf and consequently hinders the operation of the frame or the panel.

Afin de remédier à cet inconvénient on a déjà proposé de réaliser la tige de manoeuvre en deux parties reliées entre elles par un dispositif d'accouplement disposé soit à l'intérieur même du coffre de la serrure, soit à l'extérieur de ce coffre. Les dispositifs d'accouplement interne présentent une grande complexité et sont délicats à poser. Les dispositifs montés à l'extérieur sont plus simples.In order to remedy this drawback, it has already been proposed to produce the operating rod in two parts connected to each other by a coupling device arranged either inside the trunk of the lock, or outside this trunk. The internal coupling devices are very complex and are difficult to install. The devices mounted outside are simpler.

Un exemple se rapprochant de cette deuxième solution est donné dans le US-A-1 589496 qui décrit, conformément au préambule de la revendication 1, une serrure comportant un mécanisme d'actionnement d'au moins un pène comprenant un fouillot destiné à transmettre au pène l'action d'une tige de manoeuvre entraînée par une béquille de commande, et pourvu d'un bras repoussé élastiquement en position de repos, et des moyens de débrayage permettant un déplacement angulaire de 90° de la béquille dans le sens contraire à celui de l'actionnement de la serrure, sans entraînement de cette dernière. Les moyens de débrayage (ergot se déplaçant dans une rainure circonférentielle) sont montés entre la tige de manoeuvre et la béquille située du côté du cadre ou du panneau à manoeuvrer par rapport au vantail, et accouplent ces organes dans leur position normale d'actionnement de la serrure.An example approaching this second solution is given in US-A-1 589496 which describes, in accordance with the preamble of claim 1, a lock comprising a mechanism for actuating at least one bolt comprising a follower intended to transmit to the leads the action of an operating rod driven by a control stand, and provided with an elastically pushed arm in the rest position, and declutching means allowing an angular displacement of 90 ° of the stand in the opposite direction to that of actuating the lock, without driving the latter. The declutching means (lug moving in a circumferential groove) are mounted between the operating rod and the stand situated on the side of the frame or of the panel to be maneuvered relative to the leaf, and couple these members in their normal actuation position. the lock.

Leur réalisation est simple mais le dispositif d'accouplement présente cependant un volume relativement important, de sorte qu'un logement spécial doit être prévu et que la pose de la serrure s'en trouve rendue plus complexe.Their realization is simple but the coupling device however has a relatively large volume, so that a special housing must be provided and that the installation of the lock is made more complex.

Par ailleurs, une tige de manoeuvre pourvue d'un dispositif d'accouplement est d'un prix de revient très élevé par rapport à une tige de manoeuvre ordinaire.Furthermore, an operating rod provided with a coupling device has a very high cost price compared to an ordinary operating rod.

L'invention vise donc à remédier aux inconvénients précités et à créer une serrure dont la construction permette d'utiliser une tige de manoeuvre classique d'une seule pièce et de déplacer librement cette tige de manoeuvre dans le sens opposé au sens d'actionnement de la serrure, d'un angle nécessaire au dégagement du vantail en vue de permettre la manoeuvre d'un cadre ou d'un panneau devant être placé sur le vantail ou retiré de celui-ci.The invention therefore aims to remedy the aforementioned drawbacks and to create a lock, the construction of which makes it possible to use a conventional operating rod in one piece and to freely move this operating rod in the opposite direction to the actuation direction of the lock, at an angle necessary to release the leaf in order to allow the operation of a frame or panel to be placed on the leaf or removed from it.

Elle a donc pour objet une serrure du type ci- dessus, qui comporte en outre un manchon intermédiaire qui est monté à rotation, d'une part dans le fouillot et, d'autre part, dans le coffre de la serrure, ledit fouillot, comportant un orifice de réception de la tige de manoeuvre, et étant pourvu d'un bec destiné à venir en prise avec le bras du fouillot lors du déplacement en rotation de la tige de manoeuvre dans le sens de l'actionnement de la serrure, ainsi qu'une butée destinée à arrêter la rotation du bec après un déplacement angulaire déterminé de la tige de manoeuvre, dans le sens contraire au sens d'actionnement de la serrure.It therefore relates to a lock of the above type, which further comprises an intermediate sleeve which is rotatably mounted, on the one hand in the follower and, on the other hand, in the trunk of the lock, said follower, comprising an opening for receiving the operating rod, and being provided with a spout intended to come into engagement with the arm of the follower during the rotational movement of the operating rod in the direction of actuation of the lock, thus that a stop intended to stop the rotation of the spout after a determined angular displacement of the operating rod, in the opposite direction to the direction of actuation of the lock.

D'autres caractéristiques de l'invention apparaîtront au cours de la description qui va suivre, faite en référence au dessin annexé, donnée uniquement à titre d'exemple et sur lequel :

  • la Figure 1 est une vue en élévation et avec un arrachement partiel d'une serrure suivant l'invention, les éléments de cette serrure se trouvant dans la position normale d'actionnement du pène ;
  • la Figure 2 est une coupe partielle suivant la ligne 2-2 de la Fig. 1 et,
  • la Figure 3 est une vue analogue à celle de la Fig. 1 montrant la béquille de la serrure en position escamotée.
Other characteristics of the invention will appear during the description which follows, given with reference to the appended drawing, given solely by way of example and in which:
  • Figure 1 is an elevational view with a partial cutaway of a lock according to the invention, the elements of this lock being in the normal position of actuation of the bolt;
  • FIG. 2 is a partial section along line 2-2 of FIG. 1 and,
  • FIG. 3 is a view similar to that of FIG. 1 showing the handle of the lock in the retracted position.

La serrure suivant l'invention comporte un pène 1 monté déplaçable perpendiculairement à une têtière 2 au moyen d'un mécanisme d'actionnement logé dans un coffre ou boîtier 3. Ce mécanisme d'actionnement comporte notamment un fouillot 4 qui peut se déplacer en rotation dans le coffre 3. Ce fouillot 4 qui agit sur le pène 1 est pourvu d'une branche ou bras 5 sollicitée par un ressort 6 de rappel du fouillot 4 en position de repos.The lock according to the invention comprises a bolt 1 mounted displaceable perpendicularly to a headrest 2 by means of an actuation mechanism housed in a trunk or case 3. This actuation mechanism comprises in particular a follower 4 which can move in rotation in the trunk 3. This follower 4 which acts on the bolt 1 is provided with a branch or arm 5 urged by a spring 6 for returning the follower 4 to the rest position.

Suivant l'invention, la rotation du fouillot 4 dans le coffre 3 de la serrure est assuré au moyen d'une pièce intermédiaire 7 montée à rotation dans un alésage correspondant ménagé dans le fouillot 4 et, comme le montre la Fig. 2, elle-même montée à rotation dans le coffre 3. Cette pièce intermédiaire 7 est constituée par un manchon pourvu en son centre d'un orifice de section carrée 8 destiné à recevoir une tige de manoeuvre 9 représentée en traits mixtes à la Fig. 2. Sur la surface extérieure du manchon 7 est ménagé un bec 10 venu de matière, destiné à coopérer avec le bras 5 du fouillot 4 pour assurer l'entraînement de ce dernier dans le sens de l'actionnement du pène 1.According to the invention, the rotation of the follower 4 in the trunk 3 of the lock is ensured by means of an intermediate piece 7 rotatably mounted in a corresponding bore formed in the follower 4 and, as shown in FIG. 2, itself rotatably mounted in the trunk 3. This intermediate piece 7 is constituted by a sleeve provided in its center with a square section orifice 8 intended to receive an operating rod 9 shown in phantom in FIG. 2. On the outer surface of the sleeve 7 is formed a spout 10 made from one piece, intended to cooperate with the arm 5 of the follower 4 to ensure the drive of the latter in the direction of actuation of the bolt 1.

Sur une partie fixe solidaire du coffre 3 est prévue une butée 11 destinée à venir arrêter la rotation du manchon intermédiaire 7 lors du déplacement d'un quart de tour de celui-ci dans le sens contraire au sens d'actionnement du pène 1.On a fixed part integral with the trunk 3 is provided a stop 11 intended to come to stop the rotation of the intermediate sleeve 7 during the displacement of a quarter turn of the latter in the direction opposite to the direction of actuation of the bolt 1.

La butée d'arrêt précipitée 11 peut également être constituée par une tige fixée dans le coffre 3 de la serrure.The precipitated stop 11 can also be constituted by a rod fixed in the trunk 3 of the lock.

Sur la Fig. 1, les éléments de la serrure sont représentés en position normale d'actionnement du pène 1. On constate sur cette Fig. que le bec 10 étant en prise avec la branche 5 du fouillot 4, la béquille B se trouve en position à peu près horizontale. Il suffit d'appuyer sur cettte béquille pour provoquer l'effacement du pène 1.In Fig. 1, the elements of the lock are shown in the normal actuation position of the bolt 1. It can be seen in this FIG. that the spout 10 being in engagement with the branch 5 of the follower 4, the stand B is in a roughly horizontal position. Just press this stand to erase the bolt 1.

En revanche, sur la Fig. 3, on constate que le manchon intermédiaire 7 a subi une rotation dans le sens opposé au sens d'actionnement du pène 1, ce qui a permis de placer la béquille B dans une position à peu près verticale. La partie arrière du bec 10 est arrêtée en rotation par la butée 11.On the other hand, in FIG. 3, it can be seen that the intermediate sleeve 7 has been rotated in the direction opposite to the direction of actuation of the bolt 1, which has made it possible to place the stand B in an approximately vertical position. The rear part of the spout 10 is stopped in rotation by the stop 11.

La serrure qui vient d'être décrite présente l'avantage d'incorporer le dispositif de découplage de la tige de manoeuvre tout en présentant un aspect extérieur ordinaire.The lock which has just been described has the advantage of incorporating the device for decoupling the operating rod while having an ordinary external appearance.

Sa mise en place ne nécessite aucune opération supplémentaire d'adaptation de l'huisserie destinée à la recevoir et elle permet l'utilisation de tiges de manoeuvre de section carrée ordinaires.Its installation does not require any additional operation of adaptation of the frame intended to receive it and it allows the use of operating rods of ordinary square section.
