Description

L'invention concerne un dispositif de verrouillage pour porte, fenêtre ou analogue, selon le préambule de la revendication 1.The invention relates to a locking device for a door, window or the like, according to the preamble of claim 1.

On connaît déjà. par le document DE-A-3.231.069, un tel dispositif de verrouillage destiné à bloquer le carré de manoeuvre d'une poignée de commande. Ce dispositif de verrouillage comporte un élément fixe constitué d'une plaquette d'une certaine épaisseur dans laquelle est usiné un évidement débouchant sur le bord supérieur de cette dernière. Un élément mobile est conçu de manière à coulisser dans cet évidement et bloquer le carré de manoeuvre d'une poignée de commande. A cet effet, ledit élément fixe et l'élément mobile présentent, tous deux, un orifice central servant de passage au carré de manoeuvre précité et autorisant la mise en place du dispositif de verrouillage entre la face interne d'un ouvrant et le fût de ladite poignée. Ce dispositif de verrouillage remplace, ainsi, la rosette accompagnant, en général, ces poignées de commande.We already know. by document DE-A-3.231.069, such a locking device intended to block the operating square of a control handle. This locking device comprises a fixed element consisting of a plate of a certain thickness in which is machined a recess opening on the upper edge of the latter. A mobile element is designed so as to slide in this recess and block the operating square of a control handle. To this end, said fixed element and the movable element both have a central orifice serving as a passage to the aforementioned operating square and authorizing the installation of the locking device between the internal face of an opening leaf and the barrel of said handle. This locking device thus replaces the rosette accompanying, in general, these control handles.

De plus l'élément mobile comporte une découpe, débouchant dans l'orifice central et venant s'engager sur le carré de manoeuvre pour immobiliser celui-ci en rotation lorsque ledit élément mobile est amené en position de blocage.In addition, the movable element comprises a cutout, opening into the central orifice and coming to engage on the operating square to immobilize the latter in rotation when said movable element is brought into the blocking position.

En fait, l'élément mobile est à rappel élastique en position de blocage. Ce rappel élastique est obtenu par le biais de deux ressorts hélicoïdaux logés dans l'évidement de l'élément fixe et coopérant, respectivement, avec un épaulement usiné sur chacun des bords longitudinaux de la plaquette formant l'élément mobile.In fact, the movable element is elastic return in the locked position. This elastic return is obtained by means of two helical springs housed in the recess of the fixed element and cooperating, respectively, with a shoulder machined on each of the longitudinal edges of the plate forming the mobile element.

De plus ce dernier présente une lumière oblongue et une découpe situées, respectivement, de part et d'autre de l'orifice central et coopérant avec des ouvertures réalisées dans l'élément fixe. La présence de ces ouvertures assure le passage d'organes de fixation qui maintiennent le dispositif de verrouillage en applique sur la face interne de l'ouvrant.In addition the latter has an oblong lumen and a cutout located, respectively, on either side of the central orifice and cooperating with openings made in the fixed element. The presence of these openings ensures the passage of fixing members which hold the locking device applied to the internal face of the opening.

L'inconvénient que présente ce dispositif de verrouillage réside dans sa fonction de blocage automatique et systématique du carré de manoeuvre de la poignée de commande. En effet, un tel dispositif de verrouillage n'autorise, en aucun cas, l'ouverture bilatérale d'une porte, fenêtre ou analogue étant donné qu'il est impératif de manipuler l'élément mobile à rappel élastique pour déverrouiller cette dernière. Ceci peut être particulièrement gênant, notamment, lorsque ladite porte vient à se refermer de manière inopinée et empêche l'usager de pénétrer ou de sortir d'un local.The disadvantage of this locking device lies in its automatic and systematic blocking function of the operating square of the control handle. In fact, such a locking device in no case authorizes the bilateral opening of a door, window or the like, since it is imperative to manipulate the movable element to elastic reminder to unlock the latter. This can be particularly annoying, in particular when said door unexpectedly closes and prevents the user from entering or leaving a room.

En conséquence, ce dispositif de verrouillage connu ne peut trouver son utilité que dans des conditions particulières et non dans le cadre d'habitations traditionnelles.Consequently, this known locking device can only find its usefulness in special conditions and not in the context of traditional dwellings.

Par ailleurs, il convient de constater que l'élément mobile est simplement disposé dans l'évidement de l'élément fixe ce qui pose un certain nombre de problèmes lors de leur montage sur le carré de manoeuvre de la porte, fenêtre ou autre, ou en cas de démontage.Furthermore, it should be noted that the movable element is simply disposed in the recess of the fixed element, which poses a certain number of problems during their mounting on the operating square of the door, window or other, or in case of disassembly.

Notamment, lors de l'assemblage, il se peut que l'élément mobile se décale légèrement par rapport à l'élément fixe ce qui peut entraîner le blocage de l'ensemble au moment du serrage des organes de fixation. Ce montage s'avère d'autant plus complexe que les ressorts assurant le rappel élastique, aurait une tendance systématique à s'échapper de cet évidement de l'élément fixe.In particular, during assembly, the movable element may shift slightly relative to the fixed element, which can cause the blocking of the assembly when the fastening members are tightened. This mounting is all the more complex as the springs ensuring the elastic return, would have a systematic tendency to escape from this recess of the fixed element.

En fait, on observe que le dispositif de verrouillage ne forme, à aucun moment, un tout indivisible ce qui peut être, précisément, avantageux en vue de l'assemblage ou du démontage, mais, aussi, dans le cadre du stockage, soit chez le fabricant, soit au niveau de l'utilisateur menuisier.In fact, it is observed that the locking device does not form, at any time, an indivisible whole which can be, precisely, advantageous for assembly or disassembly, but, also, in the context of storage, either at the manufacturer, or at the level of the carpenter user.

Finalement, le guidage de l'élément mobile qui s'opère, dans ce dispositif de verrouillage connu, entre le fond de l'évidement correspondant à l'élément fixe et la face de l'ouvrant de la porte ou fenêtre, est imparfait et, dans tous les cas, incertain. En effet, la qualité de ce serrage est liée au paramètre variable qu'est l'intensité de serrage des organes de fixation reliant ce dispositif de verrouillage à l'ouvrant. Ainsi et en cas d'un desserrage, il se peut que sous l'effet d'un guidage Incorrect l'on aboutisse à un disfonctionnement du dispositif.Finally, the guidance of the movable element which takes place, in this known locking device, between the bottom of the recess corresponding to the fixed element and the face of the opening of the door or window, is imperfect and , in any case, uncertain. Indeed, the quality of this tightening is linked to the variable parameter that is the tightening intensity of the fastening members connecting this locking device to the opening. Thus and in the event of a loosening, it may be that under the effect of an incorrect guidance, the device will malfunction.

La présente invention a pour but de remédier à ces inconvénients. L'invention telle qu'elle est caractérisée dans la revendication 1, permet de résoudre le problème et consiste en un dispositif de verrouillage pour porte, fenêtre ou analogue comprenant :

  • a) un élément fixe ;
  • b) un élément mobile coulissant dans l'élément fixe et comportant une découpe agissant directement sur le carré de manoeuvre d'une poignée de commande pour assurer son blocage ;
  • c) et des moyens pour immobiliser, en position verrouillée, l'élément mobile par rapport à l'élément fixe ;

dispositif de verrouillage caractérisé par le fait que lesdits moyens assurent aussi bien l'immobilisation en position verrouillée qu'en position déverrouillée de l'élément mobile par rapport à l'élément fixe, ces moyens étant formés :
  • par deux ergots disposés sur chacun des bords longitudinaux de l'élément mobile et venant s'engager dans des lumières réalisées dans l'élément fixe, celui-ci comportant sur sa face dorsale des rainures situées, respectivement, dans le prolongement des lumières et dans lesquelles coulissent lesdits ergots de l'élément mobile ;
  • et par des éléments élastiques faisant saillie par rapport au fond des rainures dudit élément fixe et venant s'imbriquer faiblement dans des évidements de forme hémisphérique présents dans la face avant des ergots de l'élément mobile lorsque celui-ci est en position de blocage ou de déblocage du carré de manoeuvre ;

lesdits ergots assurant, d'une part, l'assemblage par simple emboîtement de l'élément mobile dans l'élément fixe au travers des lumières et, d'autre part, le maintien et le guidage par les rainures de cet élément mobile par rapport audit élément fixe.The present invention aims to remedy these drawbacks. The invention as characterized in claim 1, solves the problem and consists of a locking device for door, window or the like comprising:
  • a) a fixed element;
  • b) a movable element sliding in the fixed element and comprising a cutout acting directly on the operating square of a control handle to ensure its blocking;
  • c) and means for immobilizing, in the locked position, the movable element relative to the fixed element;

locking device characterized in that said means ensure both immobilization in the locked position and in the unlocked position of the movable element relative to the fixed element, these means being formed:
  • by two pins arranged on each of the longitudinal edges of the movable element and engaging in openings made in the fixed element, the latter comprising on its dorsal face grooves situated, respectively, in the extension of the openings and in which slide said pins of the movable element;
  • and by elastic elements projecting with respect to the bottom of the grooves of said fixed element and which slightly overlap in recesses of hemispherical shape present in the front face of the lugs of the movable element when the latter is in the locked position or unlocking the operating square;

said pins ensuring, on the one hand, the assembly by simple fitting of the movable element in the fixed element through the slots and, on the other hand, the maintenance and guidance by the grooves of this movable element relative said fixed element.

Les avantages obtenus grâce à cette invention consistent, essentiellement, en ce que la commande du verrouillage ou du déverrouillage d'une porte ou fenêtre munie d'un tel dispositif, impose l'intervention de l'usager. Par ailleurs, la présence d'ergots disposés au niveau des bords longitudinaux de l'élément mobile et s'insérant dans des ouvertures pratiquées dans l'élément fixe avant de coulisser dans des rainures présentes au niveau de la face dorsale de ce dernier, non seulement, permet d'obtenir un parfait guidage de cet élément mobile par rapport à l'élément fixe, mais en outre, autorise leur assemblage et leur maintien par simple emboîtement. Une telle solution s'avère, finalement, particulièrement intéressante, financièrement parlant. En effet, cet assemblage, d'une part, ne fait intervenir aucune pièce supplémentaire tel qu'un organe de fixation ou autre et, d'autre part, il peut être envisagé, soit au niveau de l'unité de fabrication du dispositif de verrouillage, soit au moment du montage de ce dernier sur l'ouvrant d'une porte ou fenêtre et, ce, sans que cela n'entraîne un surcoût à quelque niveau que ce soit.The advantages obtained thanks to this invention consist, essentially, in that the control of the locking or unlocking of a door or window provided with such a device, requires the intervention of the user. Furthermore, the presence of pins arranged at the longitudinal edges of the movable element and fitting into openings made in the fixed element before sliding in grooves present at the dorsal face of the latter, not only, allows perfect guidance of this movable element to be obtained compared to the fixed element, but in addition, allows their assembly and their maintenance by simple interlocking. Ultimately, such a solution turns out to be particularly interesting, financially speaking. Indeed, this assembly, on the one hand, does not involve any additional part such as a fixing member or other and, on the other hand, it can be envisaged, either at the level of the manufacturing unit of the device. locking, either at the time of mounting the latter on the opening of a door or window, without this resulting in any additional cost whatsoever.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.The invention is set out below in more detail with the aid of drawings representing only one embodiment.

La figure 1 représente en élévation le dispositif de verrouillage conforme à l'invention.Figure 1 shows in elevation the locking device according to the invention.

La figure 2 représente latéralement le dispositif de verrouillage représenté dans la figure 1.FIG. 2 represents the locking device shown in FIG. 1 laterally.

La figure 3 représente en plan et en coupe selon III-III le dispositif de verrouillage de la figure 1.FIG. 3 shows in plan and in section along III-III the locking device of FIG. 1.

L'invention telle que représentée dans les différentes figures, concerne un dispositif de verrouillage 1 pour porte ou fenêtre comportant des moyens de blocage 2 du carré de manoeuvre 3 d'une poignée de commande de porte ou fenêtre, cette poignée n'ayant pas été représentée.The invention as shown in the various figures, relates to a locking device 1 for door or window comprising locking means 2 of the operating square 3 of a door or window control handle, this handle not having been represented.

Ce dispositif de verrouillage 1, intercalé entre la face intérieure de l'ouvrant de la porte ou fenêtre et le fût de la poignée de commande, est enfilé sur le carré de manoeuvre 3 de ladite poignée. Il est, par ailleurs, composé de deux éléments, à savoir un élément fixe 4 et un élément mobile 5. L'élément mobile 5 est monté coulissant dans l'élément fixe 4 et comporte les moyens de blocage 2 du carré de manoeuvre 3 de la poignée de commande. Il est à noter que ce dispositif de verrouillage 1 est parfaitement symétrique par rapport au plan médian vertical 6.This locking device 1, interposed between the inner face of the door or window opening and the barrel of the control handle, is threaded onto the operating square 3 of said handle. It is, moreover, composed of two elements, namely a fixed element 4 and a mobile element 5. The mobile element 5 is slidably mounted in the fixed element 4 and comprises the locking means 2 of the operating square 3 of the control handle. It should be noted that this locking device 1 is perfectly symmetrical with respect to the vertical median plane 6.

L'élément fixe 4 est constitué d'une plaquette fixe 7 métallique ou plastique, de forme préférentiellement rectangulaire et d'épaisseur 8 réduite. Cette plaquette fixe 7 présente, sur sa face frontale 9 et dans le sens longitudinal, un évidement 10 débouchant sur le bord supérieur 11 de ladite plaquette fixe 7. La profondeur 12 de l'évidement 10 est approximativement égale à la moitié de l'épaisseur 8 de cette plaquette fixe 7.The fixed element 4 consists of a fixed metal or plastic plate 7, preferably rectangular in shape and of reduced thickness 8. This fixed plate 7 has, on its front face 9 and in in the longitudinal direction, a recess 10 opening onto the upper edge 11 of said fixed plate 7. The depth 12 of the recess 10 is approximately equal to half the thickness 8 of this fixed plate 7.

Dans cet évidement 10 vient se placer l'élément mobile 5. Ce dernier est constitué d'une plaquette, de préférence métallique dont la forme est en concordance avec celle de l'évidement 10. A cet effet, l'élément mobile 5 présente une largeur 13 légèrement inférieure à la largeur de l'évidement 10. D'autre part, l'épaisseur 14 de la plaquette constituant l'élément mobile 5 est légèrement inférieure à la profondeur 12 de l'évidement 10. Ainsi, l'élément mobile 5 peut coulisser librement dans l'évidement 10 de la plaquette fixe 7.In this recess 10 is placed the movable element 5. The latter consists of a plate, preferably metallic, the shape of which is in concordance with that of the recess 10. For this purpose, the movable element 5 has a width 13 slightly less than the width of the recess 10. On the other hand, the thickness 14 of the plate constituting the movable element 5 is slightly less than the depth 12 of the recess 10. Thus, the movable element 5 can slide freely in the recess 10 of the fixed plate 7.

Après montage de l'élément mobile 5 dans l'élément fixe 4, le dispositif de verrouillage 1 est engagé sur le carré de manoeuvre 3 de la poignée de commande de la porte ou fenêtre. A cet effet, la plaquette fixe 7 et l'élément mobile 5 comportent un orifice central 28, 29 dans lequel est engagé le carré de manoeuvre 3.After mounting the movable element 5 in the fixed element 4, the locking device 1 is engaged on the operating square 3 of the control handle of the door or window. To this end, the fixed plate 7 and the movable element 5 comprise a central orifice 28, 29 in which the operating square 3 is engaged.

L'élément mobile 5 présente, en outre, une découpe 30 débouchant dans l'orifice central 29, cette découpe 30 étant disposée dans le sens longitudinal du dispositif de verrouillage 1. Par ailleurs, cette découpe 30 présente une largeur 31 légèrement supérieure à la longueur d'un coté 32 du carré de manoeuvre 3 et, par voie de conséquence, est inférieure à la diagonale du carré de manoeuvre 3.The movable element 5 also has a cutout 30 opening into the central orifice 29, this cutout 30 being arranged in the longitudinal direction of the locking device 1. Furthermore, this cutout 30 has a width 31 slightly greater than the length of one side 32 of the operating square 3 and, consequently, is less than the diagonal of the operating square 3.

Ainsi, lorsque l'élément mobile 5 est en position haute (tel que représenté dans la figure 1), le carré de manoeuvre 3 est engagé dans l'orifice central 29 de l'élément mobile 5 autorisant, de ce fait, la libre rotation dudit carré de manoeuvre 3. Par contre, sous l'action d'une pression exercée sur l'extrémité supérieure 33 de l'élément mobile 5, la découpe 30 vient s'engager sur le carré de manoeuvre 3 immobilisant ce dernier en rotation.Thus, when the movable element 5 is in the high position (as shown in FIG. 1), the operating square 3 is engaged in the central orifice 29 of the movable element 5 thereby allowing free rotation said operating square 3. By cons, under the action of a pressure exerted on the upper end 33 of the movable member 5, the cutout 30 engages on the operating square 3 immobilizing the latter in rotation.

Cette coopération de la découpe 30 avec le carré de manoeuvre 3, lors du coulissement de l'élément mobile 5 dans l'élément fixe 4, constitue les moyens de blocage 2 du dispositif de verrouillage 1.This cooperation of the cutout 30 with the operating square 3, during the sliding of the mobile element 5 in the fixed element 4, constitutes the locking means 2 of the locking device 1.

La plaquette fixe 7 comporte, également, deux autres orifices 34 et 35 disposés de part et d'autre de l'orifice central 28 et servant au passage d'organes de fixation tels que vis ou autres. De même, l'élément mobile 5 présente une lumière oblongue 36 et une découpe 37 dans lesquelles viennent s'engager lesdits organes de fixation. Ces derniers coopèrent avec le chant inférieur de la lumière oblongue 36 et le chant supérieur de la découpe 37 pour limiter la course de l'élément mobile 5 dans l'élément fixe 4. La longueur de cette course correspond, sensiblement, à la longueur de la découpe 30 de sorte que l'élément mobile 5 coulisse entre une position de verrouillage et une position de déverrouillage.The fixed plate 7 also includes two other orifices 34 and 35 arranged on either side of the central orifice 28 and serving for the passage of fasteners such as screws or the like. Likewise, the movable element 5 has an oblong opening 36 and a cutout 37 in which the said fixing members engage. The latter cooperate with the lower edge of the oblong slot 36 and the upper edge of the cutout 37 to limit the stroke of the movable element 5 in the fixed element 4. The length of this stroke corresponds, substantially, to the length of the cutout 30 so that the movable element 5 slides between a locking position and an unlocking position.

De plus, l'élément mobile 5 comporte, à l'extrémité supérieure 33, une languette de commande 38 facilitant la manoeuvre du dispositif de verrouillage 1.In addition, the movable element 5 comprises, at the upper end 33, a control tab 38 facilitating the operation of the locking device 1.

Le dispositif de verrouillage 1 consiste à donner à l'usager la possibilité de bloquer à volonté le carré de manoeuvre d'une poignée de commande de porte, fenêtre ou analogue. Dans ce but, ce dispositif de verrouillage est pourvu de moyens 39 pour immobiliser, en position verrouillée ou déverrouillée, l'élément mobile 5 par rapport à l'élément fixe 4. Il est, en effet, indispensable d'éviter un blocage ou un déblocage inopiné dudit carré de manoeuvre sans l'intervention de l'usager. Ceci pourrait empêcher à ce dernier de sortir ou d'entrer dans un local ainsi verrouillé, ou, au contraire, faciliter l'entrée dans une habitation à un aigrefin.The locking device 1 consists in giving the user the possibility of blocking at will the operating square of a door, window or similar control handle. For this purpose, this locking device is provided with means 39 for immobilizing, in the locked or unlocked position, the movable element 5 relative to the fixed element 4. It is, in fact, essential to avoid a blockage or a unexpected unlocking of said operating square without user intervention. This could prevent the latter from leaving or entering a room thus locked, or, on the contrary, facilitate entry into a home for a shark.

En fait, ces moyens 39 sont constitués, d'une part, par deux ergots 17, 18 disposés sur chacun des bords longitudinaux 15, 16 de l'élément mobile 5 et venant s'engager dans des lumières 19, 20, 21, 22 réalisées dans la plaquette fixe 7. Ces ergots 17, 18, de forme spécifique, sont légèrement décalés par rapport au plan de l'élément mobile 5 de manière à pouvoir s'engager dans des rainures 23, 24, 25, 26 réalisées dans la face dorsale 27 de la plaquette fixe 7, ces rainures 23, 24, 25, 26 étant situées dans le prolongement des lumières respectivement 19, 20, 21, 22.In fact, these means 39 are constituted, on the one hand, by two lugs 17, 18 arranged on each of the longitudinal edges 15, 16 of the movable element 5 and coming to engage in slots 19, 20, 21, 22 made in the fixed plate 7. These pins 17, 18, of specific shape, are slightly offset from the plane of the movable element 5 so as to be able to engage in grooves 23, 24, 25, 26 made in the dorsal face 27 of the fixed plate 7, these grooves 23, 24, 25, 26 being located in the extension of the slots 19, 20, 21, 22 respectively.

D'autre part, les moyens 39, servant à immobiliser l'élément mobile 5 par rapport à l'élément fixe 4 en position verrouillée ou déverrouillée, sont complétés par des éléments élastiques (non représentés sur les figures) insérés dans les rainures 23, 24, 25, 26 de la plaquette fixe 7 et coopérant avec les ergots 17, 18. Plus précisément, ces éléments élastiques ont pour fonction d'augmenter, sensiblement, les forces de frottement exercées sur les ergots 17, 18 à l'intérieur desdites rainures 23, 24, 25, 26 lorsque l'élément mobile 5 vient à atteindre ses positions extrêmes de blocage ou de déblocage du carré de manoeuvre.On the other hand, the means 39, serving to immobilize the mobile element 5 relative to the fixed element 4 in the locked or unlocked position, are supplemented by elastic elements (not shown in the figures) inserted in the grooves 23, 24, 25, 26 of the fixed plate 7 and cooperating with the pins 17, 18. More specifically, these elastic elements have the function of increasing, appreciably, the friction forces exerted on the pins 17, 18 inside said grooves 23, 24, 25, 26 when the movable element 5 comes to reach its extreme positions of blocking or unblocking of the operating square.

Ainsi, selon un premier mode de réalisation, les éléments élastiques sont constitués par des organes en matière plastique, métallique ou autre, faisant saillie par rapport au fond 40 des rainures 23, 24, 25, 26. Selon un autre mode de réalisation, on insère dans le fond 40 de ces dernières et à des emplacements déterminés, des billes à rappel élastique destinées à venir s'imbriquer faiblement dans un évidement de forme hémisphérique usiné dans la face avant 41 des ergots 17, 18, lorsque l'élément mobile 5 est en position de blocage ou de déblocage du carré de manoeuvre 3.Thus, according to a first embodiment, the elastic elements consist of members made of plastic, metallic or other material, projecting relative to the bottom 40 of the grooves 23, 24, 25, 26. According to another embodiment, inserts into the bottom 40 of the latter and at determined locations, elastic return balls intended to come to nest slightly in a hemispherical recess machined in the front face 41 of the lugs 17, 18, when the movable element 5 is in the locking or unlocking position of the operating square 3.

En raison de ces particularités, le dispositif de verrouillage 1 peut être commandé selon les désirs de l'usager, sans qu'il n'y ait un risque de fonctionnement aléatoire. Par ailleurs, son montage est facilité grâce a l'assemblage possible entre l'élément fixe 4 et l'élément mobile 5 par simple emboîtement.Because of these features, the locking device 1 can be controlled according to the wishes of the user, without there being a risk of random operation. Furthermore, its mounting is facilitated by the possible assembly between the fixed element 4 and the movable element 5 by simple interlocking.

Un tel dispositif de verrouillage 1, conforme à la présente invention est adaptable sur tout type de poignée de commande d'une porte ou fenêtre et pourra aisément s'escamoter derrière la rosette accompagnant, en général, ladite poignée de commande.Such a locking device 1, in accordance with the present invention is adaptable to any type of control handle of a door or window and can easily be retracted behind the rosette accompanying, in general, said control handle.

A cet effet, selon un mode de réalisation de l'invention, le dispositif de verrouillage 1 et la rosette sont fixés sur l'ouvrant de la porte ou fenêtre par des organes de fixation connus.To this end, according to one embodiment of the invention, the locking device 1 and the rosette are fixed to the opening of the door or window by known fixing members.
