Description

L'invention concerne une ferrure de verrouillage pour ouvrants coulissants composée :
- d'une embase formée par une cornière dont une aile est fixée en applique sur la face interne de l'ouvrant et dont l'autre aile se présente saillante par rapport à ce dernier ;
- d'une poignée de commande montée pivotante sur ladite embase et comportant un organe de verrouillage destiné à coopérer avec une gâche ou équivalent disposée sur le dormant.
The invention relates to a locking fitting for sliding doors comprising:
- A base formed by an angle iron, one wing of which is attached to the internal surface of the opening leaf and the other wing of which is protruding from the latter;
- A control handle pivotally mounted on said base and comprising a locking member intended to cooperate with a keeper or equivalent disposed on the frame.

La présente invention concerne l'industrie spécialisée dans le domaine de la quincaillerie du bâtiment.The present invention relates to the industry specialized in the field of building hardware.

On connaît déjà par le document FR-A-2.506.372, une ferrure de verrouillage reprenant les éléments constitutifs tels qu'énumérés ci-dessus. Ainsi, cette ferrure de verrouillage comporte une embase venant en applique sur la face interne du montant avant d'un ouvrant coulissant. Cette embase supporte une poignée de commande à laquelle est fixé un organe de verrouillage coopérant avec une gâche, disposée sur le dormant de la porte, fenêtre ou analogue, lors de la fermeture de cette dernière.Document FR-A-2,506,372 already discloses a locking fitting incorporating the constituent elements as listed above. Thus, this locking fitting comprises a base that comes to bear on the internal face of the front upright of a sliding leaf. This base supports a control handle to which is fixed a locking member cooperating with a keeper, disposed on the frame of the door, window or the like, when the latter is closed.

Plus précisément, l'embase est constitutée par une cornière à angle obtus dont une aile est rapportée, par l'intermédiaire d'éléments de fixation tels que vis, rivets ou autres, sur ladite face interne du montant avant de l'ouvrant, l'autre aile se présentant saillante par rapport au plan de ce dernier. Dans l'angle intérieur de cette cornière est aménagée une rainure verticale permettant d'accueillir un bourrelet hémicylindrique, solidaire de la poignée de commande, et constituant les moyens de rotation de cette dernière. Quant à la structure précise de ladite poignée de commande, elle est formée d'une aile radiale comportant sur l'un de ses chants verticaux le bourrelet hémicylindrique précité. Sur le chant verticaux opposé est rapportée une aile de forme curviligne, dite circonférentielle, en raison de sa disposition et de son déplacement sur rapport à l'axe de pivotement formé, substantiellement, par ledit bourrelet hémicylindrique.More specifically, the base is constituted by an obtuse angle angle, one wing of which is attached, by means of fixing elements such as screws, rivets or the like, to said internal face of the front upright of the opening, l other wing projecting from the plane thereof. In the inner corner of this angle iron is arranged a vertical groove for accommodating a semi-cylindrical bead, integral with the control handle, and constituting the means of rotation of the latter. As for the precise structure of said handle control, it is formed by a radial wing comprising on one of its vertical edges the aforementioned semi-cylindrical bead. On the opposite vertical edge is attached a curvilinear wing, called circumferential, due to its arrangement and its displacement relative to the pivot axis formed, substantially, by said semicylindrical bead.

L'organe de verrouillage, coopérant avec la gâche disposée sur le dormant, se présente sous forme d'une lame fixée sur l'aile radiale de la poignée de commande et comportant une extrémité en forme d'un bec susceptible d'entrer en liaison avec un élément de conception identique à un crochet que constitue la gâche.The locking member, cooperating with the keeper disposed on the frame, is in the form of a blade fixed on the radial wing of the control handle and having an end in the form of a spout capable of coming into contact with a design element identical to a hook constituted by the keeper.

Cette ferrure de verrouillage connue, est également munie de moyens de rappel élastiques de la poignée de commande en position verrouillée, ce que confère à ladite ferrure un caractère automatique en assurant, systématiquement le verrouillage de la porte, fenêtre ou analogue, en cas de fermeture de l'ouvrant.This known locking fitting is also provided with elastic return means of the control handle in the locked position, which gives said fitting an automatic nature by systematically locking the door, window or the like in the event of closing. of the opening.

Ces moyens de rappel élastiques sont constitués par un ressort hélicoïdal précontraint disposé entre l'aile saillante de la cornière formant l'embase et l'aile radiale de la poignée de commande. Ainsi, en agissant sur cette dernière, l'usager provoque la compression de ce ressort hélicoïdal et le dégagement de l'organe de verrouillage de sa gâche correspondante. En fin de coulissement de l'ouvrant, le relâchement de la poignée de commande libère ces moyens de rappel élastiques ramenant la ferrure de verrouillage dans sa position de blocage.These elastic return means consist of a pre-stressed helical spring disposed between the projecting wing of the angle iron forming the base and the radial wing of the control handle. Thus, by acting on the latter, the user causes the compression of this helical spring and the release of the locking member from its corresponding keeper. At the end of the sliding of the opening, the release of the control handle releases these elastic return means bringing the locking fitting back into its locked position.

Or, dans une telle disposition, une manoeuvre intempestive de l'ouvrant, exécutée, par exemple, par un enfant, peut engendrer le verrouillage de la porte, fenêtre ou analogue, et condamner l'usager venant de franchir le vantail ouvert à rester à l'extérieur de l'habitation.However, in such an arrangement, an untimely operation of the opening, executed, for example, by a child, can cause the locking of the door, window or the like, and order the user who has just crossed the open leaf to stay outside the house.

Pour remédier à cet inconvénient et éviter de tels incidents, il est prévu, selon le document antérieur, de munir la ferrure de verrouillage d'un dispositif de blocage permettant de maintenir la poignée de commande en position verrouillée. Ce dispositif de blocage se compose, d'une part, d'une rainure, de section ovale, dans laquelle est engagé le bourrelet hémicylindrique de la poignée de commande de manière à autoriser un déplacement perpendiculaire de cette dernière par rapport à son axe de pivotement. D'autre part, il est prévu, sur le chant vertical de l'aile saillante de la cornière constituant l'embase, une cavité susceptible d'accueillir un bossage présent sur la face inférieure de l'aile circonférentielle formant l'élément de préhension de la poignée de commande.To overcome this drawback and avoid such incidents, provision is made, according to the prior document, to provide the locking fitting with a locking device making it possible to keep the control handle in the locked position. This locking device consists, on the one hand, of a groove, of oval section, in which is engaged the semi-cylindrical bead of the control handle so as to allow a perpendicular movement of the latter relative to its pivot axis . On the other hand, there is provided, on the vertical edge of the projecting wing of the angle iron constituting the base, a cavity capable of receiving a boss present on the underside of the circumferential wing forming the gripping element. the control handle.

Ce dispositif de blocage est complété par les moyens de rappel élastiques de la poignée de commande en position de verrouillage, ces moyens exerçant, également, une action radiale sur ladite poignée de commande pour assurer le déplacement transversal de celle-ci par rapport à son axe de rotation. L'intérêt de cette action radiale des moyens de rappel élastiques consiste à amener le bossage précité de l'aile circonférentielle dans la cavité correspondante et, finalement, maintenir la poignée de commande en position déverrouillée.This locking device is completed by the elastic return means of the control handle in the locked position, these means also exerting a radial action on said control handle to ensure the transverse movement of the latter relative to its axis. of rotation. The advantage of this radial action of the elastic return means consists in bringing the aforementioned boss of the circumferential wing into the corresponding cavity and, finally, maintaining the control handle in the unlocked position.

Un tel dispositif de blocage impose, après déverrouillage de la porte ou autre, l'intervention de l'usager pour libérer, à nouveau, la poignée de commande, celle-ci reprenant alors, sa position verrouillée sous l'action des moyens de rappel élastiques.Such a locking device requires, after unlocking the door or other, the intervention of the user to release, again, the control handle, the latter then resuming, its locked position under the action of the return means elastic.

Bien qu'apportant une amélioration certaine sur le plan de la sécurité, ce type de ferrure munie d'un tel dispositif de blocage présente un certain nombre d'inconvénients, essentiellement dus à la conception particulière et à la fiabilité réduite de ce dernier.Although providing a certain improvement in terms of security, this type of fitting provided with such a locking device has a number of drawbacks, essentially due to the particular design and the reduced reliability of the latter.

En effet, les moyens de rappel élastiques, à action radiale, présentent une configuration spécifique, non standard, en raison de leur agissement sur la poignée de commande, d'une part, pour la ramener en position verrouillée et, d'autre part, pour lui conférer un déplacement transversal à son axe de pivotement.Indeed, the elastic return means, with radial action, have a specific, non-standard configuration, due to their action on the control handle, on the one hand, to bring it back into the locked position and, on the other hand, to give it a movement transverse to its pivot axis.

Par ailleurs, ce dispositif de blocage s'avère peu fiable et totalement inefficace en cas de fatigue des moyens de rappel élastiques. En effet, on constate que seule leur action radiale assure le blocage de la poignée de commande en position déverrouillée. Cependant, ces mêmes moyens de rappel élastiques exercent, simultanément, une pression sur ladite poignée de commande ayant tendance à dissoudre la liaison, bossage-cavité, cette action étant, de ce fait, totalement antagoniste à la précédente.Furthermore, this blocking device proves to be unreliable and totally ineffective in the event of fatigue of the elastic return means. Indeed, it is found that only their radial action ensures the locking of the control handle in the unlocked position. However, these same elastic return means exert, simultaneously, a pressure on said control handle tending to dissolve the connection, boss-cavity, this action being, therefore, completely antagonistic to the previous one.

En conséquence, il est nécessaire de trouver un parfait compromis entre le coefficient de raideur, dans le sens axial, de ces moyens de rappel élastiques et leur coefficient de raideur radiale pour assurer un bon fonctionnement du dispositif de blocage tout en autorisant une manipulation aisée de la poignée de commande.Consequently, it is necessary to find a perfect compromise between the coefficient of stiffness, in the axial direction, of these elastic return means and their coefficient of radial stiffness to ensure correct operation of the blocking device while allowing easy manipulation of the control handle.

Bien entendu, en théorie, ces coefficients de raideur peuvent être déterminés strictement, pourtant, ceci paraît bien plus délicat dans le cadre de la conception du produit. En effet, en cas de fatigue du matériel, celle-ci n'ayant jamais des conséquences identiques dans l'un et l'autre sens d'action de l'élément élastique, il est fort probable que le dispositif de blocage sera mis hors d'usage.Of course, in theory, these stiffness coefficients can be determined strictly, however, this seems much more delicate in the context of product design. Indeed, in the event of fatigue of the material, this never having identical consequences in both directions of action of the elastic element, it is very likely that the locking device will be put out of use.

L'aspect antagoniste des effets de ces moyens de rappel élastiques se répercute également sur le plan de la sécurité de la ferrure de verrouillage. Plus précisément, étant à considérer que la poignée de manoeuvre, maintenue déverrouillée, se trouve dans une position d'équilibre instable, une manoeuvre intempestive, même commandée par un enfant, provoquant l'entrechoquement de l'ouvrant contre le dormant, peut libérer le dispositif de blocage et finalement provoquer le verrouillage de l'ouvrant ; incident dont il convenait, justement, d'apporter une solution.The antagonistic aspect of the effects of these elastic return means also affects the security of the locking fitting. More precisely, being considered that the operating handle, kept unlocked, is in an unstable equilibrium position, an untimely operation, even commanded by a child, causing the sash to collide against the frame, can release the blocking device and finally cause the door to lock; incident for which it was right to provide a solution.

On notera, par ailleurs, qu'un dispositif de blocage de la poignée de commande en position déverrouillée n'est utile que dans le cadre d'ouvrants coulissants autorisant l'usager à sortir de l'habitation. Ceci n'est pas le cas, notamment, pour les fenêtres d'étage ne donnant accès à aucune terrasse. En conséquence, pour de tels ouvrants, il est préférable de conserver l'aspect automatique de la ferrure de verrouillage et procéder à la suppression du dispositif de blocage de la poignée de commande en position déverrouillée.Note, moreover, that a device for blocking the control handle in the unlocked position is only useful in the context of sliding doors allowing the user to leave the dwelling. This is not the case, in particular, for upstairs windows giving access to no terrace. Consequently, for such openings, it is preferable to keep the automatic appearance of the locking fitting and to proceed with the removal of the device for locking the control handle in the unlocked position.

Or, dans le cadre de la ferrure de verrouillage connue pour ouvrants coulissants, décrite dans le document antérieur précité, une telle suppression du dispositif de blocage nécessite des modifications importantes de certaines pièces constitutives de ladite ferrure de verrouillage.However, in the context of the known locking fitting for sliding doors, described in the aforementioned prior document, such removal of the locking device requires significant modifications to certain components of said locking fitting.

La présente invention a pour but de remédier aux inconvénients précités en proposant une ferrure de verrouillage comportant un dispositif de blocage de la poignée de commande en position déverrouillée qui soit particulièrement fiable et qui nécessite, obligatoirement, l'intervention d'un usager pour ramener ladite poignée de commande en position de verrouillage.The object of the present invention is to remedy the aforementioned drawbacks by proposing a locking fitting comprising a device for locking the control handle in the unlocked position which is particularly reliable and which necessarily requires: the intervention of a user to return said control handle to the locked position.

De plus, cette invention a pour objectif une standardisation du matériel intervenant dans l'une ou l'autre des conditions d'utilisation de ces ferrures de verrouillage pour ouvrants coulissants, à savoir :
- automatisme avec retour systématique de la poignée de commande en position de verrouillage ;
- ou semi-automatisme offrant le possibilité de maintenir, également, ladite poignée de commande en position déverrouillée.
In addition, the object of this invention is to standardize the equipment involved in one or other of the conditions of use of these locking fittings for sliding doors, namely:
- automation with systematic return of the control handle to the locked position;
- or semi-automatic system offering the possibility of also maintaining said control handle in the unlocked position.

Toutefois, cette standardisation du matériel, tendant vers une réduction du coût de revient global de ces ferrures de verrouillage, ne doit pas engendrer un surcroît dans la complexité des pièces utilisées ce qui pourrait anéantir totalement les effets précédents.However, this standardization of the material, tending towards a reduction in the overall cost price of these locking fittings, should not generate an increase in the complexity of the parts used, which could completely destroy the previous effects.

L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème consistant à créer une ferrure de verrouillage pour ouvrants coulissants composée :
- d'une embase formée par une cornière dont une aile est fixée en applique sur la face interne de l'ouvrant et dont l'autre aile se présente saillante par rapport à ce dernier ;
- d'une poignée de commande montée pivotante sur ladite embase et comportant un organe de verrouillage destiné à coopérer avec une gâche ou équivalent disposée sur le dormant.
The invention, as characterized in the claims, solves the problem of creating a locking fitting for sliding doors comprising:
- A base formed by an angle iron, one wing of which is attached to the internal surface of the opening leaf and the other wing of which is protruding from the latter;
- A control handle pivotally mounted on said base and comprising a locking member intended to cooperate with a keeper or equivalent disposed on the frame.

Cette ferrure de verrouillage comportant, en outre, des moyens élastiques uniques susceptibles de repousser la poignée de commande, soit dans sa position déverrouillée, soit en position verrouillée, selon le décalage angulaire conféré à ladite poignée de commande.This locking fitting further comprising unique elastic means capable of pushing back the control handle, either in its unlocked position, either in the locked position, according to the angular offset conferred on said control handle.

Selon une autre caractéristique de la présente invention, la ferrure de verrouillage comporte des moyens pour déplacer le point d'application des moyens élastiques sur la poignée de commande pour assurer le rappel constant de cette dernière en position de verrouillage.According to another characteristic of the present invention, the locking fitting comprises means for moving the point of application of the elastic means on the control handle to ensure the constant return of the latter in the locking position.

Les avantages obtenus grâce à cette invention consistent, essentiellement, en ce que des moyens élastiques de caractéristiques courantes sont en mesure de remplir la fonction de maintien de la poignée de commande en position déverrouillée sans que, pour autant, il ne soit nécessaire de disposer d'une articulation spécifique de ladite poignée de commande sur l'embase. De plus, il convient de remarquer que ces moyens élastiques assurent également, le rappel de la poignée de commande en position de verrouillage, ceci tout en évitant que cette fonction soit contraire à celles remplies dans la situation précédente.The advantages obtained thanks to this invention consist, essentially, in that elastic means of current characteristics are able to fulfill the function of maintaining the control handle in the unlocked position without, however, it being necessary to have available 'A specific articulation of said control handle on the base. In addition, it should be noted that these elastic means also ensure, the return of the control handle to the locked position, this while avoiding that this function is contrary to those fulfilled in the previous situation.

Un autre avantage que présente cette ferrure de verrouillage, conforme à l'invention, est sa polyvalence. En effet, grâce à des moyens appropriés, elle peut être, alternativement, soit automatique, soit semi-automatique, s'adaptant, ainsi, à tout type de porte, fenêtre ou analogue. Cette standardisation a permis, par ailleurs, d'aboutir à une simplification des pièces constitutives de la ferrure de verrouillage, tant sur leur nombre qu'au niveau de leur conception.Another advantage of this locking fitting according to the invention is its versatility. Indeed, thanks to appropriate means, it can be, alternatively, either automatic or semi-automatic, thus adapting to any type of door, window or the like. This standardization has also made it possible to simplify the constituent parts of the locking fitting, both in terms of their number and in terms of their design.

  • - la figure 4 représente la ferrure de verrouillage dans une position identique à celle de la figure 1, le point d'application des moyens élastiques sur la poignée de commande étant décalé de manière à repousser, systématiquement, cette dernière en position de verrouillage.
The invention is set out below, in more detail, using drawings representing only one embodiment:
  • - Figure 1 shows a schematic sectional view of the locking fitting according to the invention, the control handle being returned to its locking position;
  • - Figure 2 shows a view identical to Figure 1, the control handle being held in its unlocked position by means of elastic means designed according to the invention;

  • - Figure 4 shows the locking fitting in a position identical to that of Figure 1, the point of application of the elastic means on the control handle being offset so as to push, systematically, the latter in the locking position.

La ferrure de verrouillage 1, objet de la présente invention, et représentée dans les figures 1, 2 et 4, est plus particulièrement destinée à des portes, fenêtres ou analogues dont l'ouvrant est du type coulissant. Ainsi, cette ferrure de verrouillage 1 est composée d'une embase 2, fixée en applique sur la face interne du montant avant de l'ouvrant coulissant et sur lequel est montée, pivotante, une poignée de commande 3. Cette dernière est munie d'un organe de verrouillage 4 destiné à coopérer avec une gâche 5, disposée sur le dormant de la porte, fenêtre ou analogue.The locking fitting 1, object of the present invention, and shown in Figures 1, 2 and 4, is more particularly intended for doors, windows or the like whose opening is of the sliding type. Thus, this locking fitting 1 is composed of a base 2, fixed to the wall on the internal face of the front upright of the sliding leaf and on which is mounted, pivotally, a control handle 3. The latter is provided with a locking member 4 intended to cooperate with a keeper 5, disposed on the frame of the door, window or the like.

Plus précisément, l'embase 2 est formée par une cornière comportant une aile 6, rapportée en appui sur la face interne de l'ouvrant et une aile saillante 7 disposée perpendiculairement au plan de ce dernier.More specifically, the base 2 is formed by an angle iron comprising a wing 6, attached to bear on the internal face of the opening leaf and a projecting wing 7 disposed perpendicularly to the plane of the latter.

Sur la face interne 8 de l'aile en applique 6 est aménagée une rainure 9 dans laquelle vient se loger un bourrelet hémicylindrique 10 solidaire de la poignée de commande 3 et constituant l'axe de rotation de cette dernière. A cet effet, ladite poignée de commande 3 est formée par une aile radiale 11 comportant, sur l'un de ses chants verticaux 12, ledit bourrelet hémicylindrique 10. Une aile 13, dénommée circonférentielle en raison de sa disposition et de son déplacement par rapport à l'axe de rotation de la poignée de commande 3, est rapportée sur le chant vertical opposé 14 de cette aile radiale 11 et constitué l'élément de préhension de ladite poignée de commande 3. Quant à l'organe de verrouillage 4, solidaire de cette dernière, il est formé par une lame 15 dépendant de l'aile radiale 11 et comportant, à son extrémité libre 16, un bec 17 susceptible de coopérer avec un élément en forme de crochet 18 tel qu'une gâche 5 disposée sur le montant du dormant de la porte, fenêtre ou analogue.On the inner face 8 of the surface-mounted wing 6 is arranged a groove 9 in which is housed a semi-cylindrical bead 10 secured to the control handle 3 and constituting the axis of rotation of the latter. To this end, said control handle 3 is formed by a radial wing 11 comprising, on one of its vertical edges 12, said semi-cylindrical bead 10. A wing 13, called circumferential because of its arrangement and its displacement relative to the axis of rotation of the control handle 3, is attached to the opposite vertical edge 14 of this radial wing 11 and constituted l gripping element of said control handle 3. As for the locking member 4, integral with the latter, it is formed by a blade 15 depending on the radial wing 11 and comprising, at its free end 16, a spout 17 capable of cooperating with a hook-shaped element 18 such as a keeper 5 disposed on the amount of the door frame, window or the like.

Avantageusement et selon une caractéristique de la présente invention, la ferrure de verrouillage 1 comporte, en outre, des moyens élastiques 19, susceptibles de repousser la poignée de commande 3, alternativement, soit dans sa position de verrouillage 20, tel que représenté dans la figure 1, soit en position déverrouillée 21 correspondant à la configuration de ladite poignée de commande 3 représentée dans la figure 2.Advantageously and according to a characteristic of the present invention, the locking fitting 1 further comprises elastic means 19 capable of pushing the control handle 3 alternately, either in its locking position 20, as shown in the figure 1, or in the unlocked position 21 corresponding to the configuration of said control handle 3 shown in FIG. 2.

Cette alternative dépend, plus exactement, du déplacement angulaire conféré à la poignée de commande 3, lors de la manipulation de la ferrure de verrouillage 1. Ainsi, ces moyens élastiques 19 consistent en un élément élastique 22 relié, à l'une de ses extrémités 23, à l'aile saillante 7 de l'embase 2, l'autre extrémité 24 de cet élément élastique 22 étant fixée à l'aile radiale 11 de la poignée de commande 3.This alternative depends, more exactly, on the angular displacement imparted to the control handle 3, when handling the locking fitting 1. Thus, these elastic means 19 consist of an elastic element 22 connected, at one of its ends 23, to the projecting wing 7 of the base 2, the other end 24 of this elastic element 22 being fixed to the radial wing 11 of the control handle 3.

Plus précisément, la disposition de l'élément élastique 22 est déterminée de sorte que ses points de liaison 25, 26 respectivement sur l'embase 2 et la poignée de commande 3, sont en mesure de s'aligner avec l'axe de rotation de cette dernière, constitué, substantiellement, par le bourrelet hémicylindrique 10 au cours du pivotement de ladite poignée de commande 3.More specifically, the arrangement of the elastic element 22 is determined so that its connection points 25, 26 respectively on the base 2 and the control handle 3, are able to align with the axis of rotation of the latter, consisting essentially of the semi-cylindrical bead 10 during the pivoting of said control handle 3.

Ainsi, lors de la commande en rotation de celle-ci, cet élément élastique 22 passe par une position d'équilibre instable dans laquelle les différentes forces en présence viennent à s'annuler. De part et d'autre de ce point d'équilibre, cet élément élastique 22 provoque la rotation de la poignée de commande 3 selon des sens différents.Thus, when the latter is rotated, this elastic element 22 passes through an unstable equilibrium position in which the different forces present cancel each other out. On either side of this point of equilibrium, this elastic element 22 causes the control handle 3 to rotate in different directions.

Etant donné que le point de liaison 25 de l'élément élastique 22 sur l'embase 2 est immuable lors de la commande de la ferrure de verrouillage 1, seul le point de liaison 26 est soumis à un déplacement angulaire équivalent à celui effectué par la poignée de commande 3. De ce fait, lors de la commande de celle-ci, ce point de liaison 26 doit, obligatoirement, couper, au cours de son déplacement, le segment 27 reliant le point de liaison 25 à l'axe de pivotement de la poignée de commande 3, ce segment 27 matérialisant la ligne d'équilibre des forces.Since the connection point 25 of the elastic element 22 on the base 2 is immutable when the locking fitting 1 is ordered, only the connection point 26 is subjected to an angular displacement equivalent to that effected by the control handle 3. Therefore, when ordering it, this connection point 26 must, necessarily, cut, during its movement, the segment 27 connecting the connection point 25 to the pivot axis of the control handle 3, this segment 27 materializing the line of balance of forces.

Ainsi, lorsque ledit point de liaison 26 vient à se positionner sur ledit segment 27, entre le point de liaison 25 et l'axe de pivotement de la poignée de commande 3, l'élément élastique 22 est dans une position d'équilibre instable. En effet, dans cette disposition, la distance 28 séparant les points de liaison 25, 26 tend vers un minimum, correspondant à une compression maximale de l'élément élastique 22.Thus, when said connection point 26 is positioned on said segment 27, between the connection point 25 and the pivot axis of the control handle 3, the elastic element 22 is in an unstable equilibrium position. In fact, in this arrangement, the distance 28 separating the connection points 25, 26 tends towards a minimum, corresponding to maximum compression of the elastic element 22.

Tel que représenté dans la figure 3, cette distance 28 tend à s'accroître lorsque ledit point de liaison 26 évolue dans l'un ou l'autre sens par rapport au segment 27.As shown in FIG. 3, this distance 28 tends to increase when said connection point 26 moves in one or the other direction relative to the segment 27.

Cette transition du rappel élastique de la poignée de commande 3 en position déverrouillée 21 et verrouillée 20 peut être assurée soit en début soit en fin de rotation de la poignée de commande 3 ou encore lorsque celle-ci a atteint une position angulaire médiane. Ceci dépend des objectifs recherchés par le fabricant et, notamment, des exigences du marché. Ainsi, lorsque cette transition s'effectue en début de manipulation de la poignée de commande 3, il est donné une préférence au côté sécurité de la ferrure de verrouillage 1 en assurant, presque systématiquement, le maintien de la poignée de commande en position d'ouverture lors du déverrouillage de l'ouvrant. Dans le cas contraire, la priorité sera donnée à l'automatisme de la ferrure de verrouillage 1 tout en offrant la possibilité de maintenir la poignée de commande 3 en position déverrouillée en conférant à cette dernière une rotation maximale.This transition from the elastic return of the control handle 3 to the unlocked 21 and locked 20 position can be ensured either at the start or at the end of rotation of the control handle 3 or even when the latter has reached a median angular position. It depends on the objectives sought by the manufacturer and, in particular, market requirements. Thus, when this transition takes place at the start of manipulation of the control handle 3, preference is given to the safety side of the locking fitting 1 by ensuring, almost systematically, the maintenance of the control handle in the position of opening when the door is unlocked. Otherwise, priority will be given to the automation of the locking fitting 1 while offering the possibility of maintaining the control handle 3 in the unlocked position by giving the latter a maximum rotation.

Dans les différentes figures accompagnant la description, l'élément élastique est représenté sous forme d'un ressort à lame. Toutefois, il peut être envisagé de substituer à ce ressort tout autre élément élastique, susceptible de remplir des fonctions identiques, tel qu'un ressort hélicoïdal au analogue.In the various figures accompanying the description, the elastic element is represented in the form of a leaf spring. However, it can be envisaged to replace this spring with any other elastic element capable of fulfilling identical functions, such as a helical spring with the analog.

Avantageusement, les liaisons de l'élément élastique 22 avec l'aile saillante 7 de l'embase 2 et l'aile radiale 11 de la poignée de commande 3 sont formées par des moyens d'articulation 29. Cette caractéristique a, essentiellement, pour fonction de réduire les contraintes locales sur l'élément élastique 22 lors de la manipulation de la ferrure de verrouillage 1. On constate en effet, qu'en cas d'une liaison rigide, cet élément élastique 22 est fortement sollicité, notamment, au niveau de ses extrémités 23, 24.Advantageously, the connections of the elastic element 22 with the projecting wing 7 of the base 2 and the radial wing 11 of the control handle 3 are formed by articulation means 29. This characteristic has, essentially, for function of reducing the local stresses on the elastic element 22 during the manipulation of the locking fitting 1. In fact, it can be seen that, in the case of a rigid connection, this elastic element 22 is highly stressed, in particular at the level from its ends 23, 24.

Selon une autre caractéristique de l'invention, la ferrure de verrouillage 1 comporte des moyens 30 permettant de déplacer le point d'application des moyens élastiques 19 sur la poignée de commande 3. L'objectif de tels moyens 30 consiste à proposer à l'usager une ferrure de verrouillage standard dont les caractéristiques de fonctionnement peuvent être modifiées sans grande difficulté et sans nécessiter de changement de pièces.According to another characteristic of the invention, the locking fitting 1 comprises means 30 making it possible to move the point of application of the elastic means 19 on the control handle 3. The objective of such means 30 consists in proposing to the use a standard locking fitting whose operating characteristics can be modified without great difficulty and without requiring a change of parts.

En fait, ces moyens 30 permettant de restituer à la ferrure de verrouillage sa caractéristique automatique en assurant le rappel systématique de la poignée de commande 3 en position de verrouillage. Ceci s'effectue par un simple déplacement du point de liaison 26 de l'élément élastique 22 sur ladite poignée de commande 3. Plus précisément, ces moyens 30 sont constitués par un point de liaison 31 de l'élément élastique 22 sur l'aile radiale 11 de la poignée de commande 3 dont la position est déterminée de sorte, qu'en aucun cas, au cours de la rotation de cette dernière, il ne vienne à croiser le segment 27 reliant le point de liaison 26 au niveau de l'embase 2 et l'axe de rotation formé par le bourrelet hémicylindrique 10.In fact, these means 30 make it possible to restore its locking characteristic to its automatic characteristic by ensuring the systematic return of the control handle 3 to the locking position. This is done by a simple displacement of the connection point 26 of the elastic element 22 on said control handle 3. More specifically, these means 30 are constituted by a connection point 31 of the elastic element 22 on the wing radial 11 of the control handle 3, the position of which is determined so that, in no case, during the rotation of the latter, does it cross the segment 27 connecting the connection point 26 at the level of the base 2 and the axis of rotation formed by the semi-cylindrical bead 10.

Dans le cadre du mode de réalisation représenté sur les figures 1, 2 et 4, ce point de liaison 31 se situe dans l'angle intérieur 32 formé par l'aile radiale 11 et l'aile circonférentielle 13. Cependant, il peut être choisi une toute autre disposition pour ce point de liaison 31 tout en respectant la condition exprimée ci-dessus.In the context of the embodiment shown in FIGS. 1, 2 and 4, this connection point 31 is located in the interior angle 32 formed by the radial wing 11 and the circumferential wing 13. However, it can be chosen a completely different arrangement for this connection point 31 while respecting the condition expressed above.

Tout comme précédemment, l'extrémité 24 de l'élément élastique 22 est reliée à la poignée de commande 3 au niveau de ce point de liaison 31 par le biais de moyens d'articulation 33.As before, the end 24 of the elastic element 22 is connected to the control handle 3 at this connection point 31 by means of articulation means 33.

En dehors des avantages déjà énumérés plus haut dans cette description, on constate que la présente ferrure de verrouillage 1 est de conception particulièrement simplifiée ce qui se répercute, bien évidemment, sur son coût de revient.Apart from the advantages already listed above in this description, it can be seen that the present locking fitting 1 has a particularly simplified design, which obviously has repercussions on its cost price.

Cependant, cette simplification n'a pas été réalisée au détriment de la fiabilité du produit, ni par suite d'une conception spécifique pour une application donnée. Bien au contraire, cette ferrure de verrouillage tend à atteindre une standardisation du matériel pour ouvrant coulissant de manière à réduire l'importance des stocks chez le fabricant et les utilisateurs.However, this simplification was not achieved to the detriment of the reliability of the product, nor as a result of a specific design for a given application. On the contrary, this locking fitting tends to reach a standardization of the material for sliding door so as to reduce the importance of stocks at the manufacturer and the users.
