The striker (1) has a set of housing openings (8, 8A) that is provided as a T-section for reception of a T-shaped locking roller in a locking position. The set of housing openings is delimited by bottom that extends from two closed parallel side walls (13, 14). A covering blade (27) is arranged for defining fixing return units (15, 16) opposite the bottom of the side walls. An adjustment unit (25) adjusts distance separating the bottom of the return units. The adjustment unit is formed by the covering blade that is elastically deformable.

Description

L'invention concerne une gâche notamment pour ferrure de verrouillage de type crémone ou crémone-serrure ou similaire, comportant au moins un logement débouchant de section en T pour la réception, dans au moins une position de verrouillage d'un galet de verrouillage en T, ledit logement étant délimité par un fond d'où s'étendent deux parois latérales terminées, chacune, par un retour d'accrochage.The invention relates to a striker, in particular for a cremone or espagnolette-lock type locking fitting or the like, comprising at least one T-shaped opening opening for receiving, in at least one locking position of a T-lock roller. , said housing being delimited by a bottom from which extend two side walls completed, each by a return hooking.

La présente invention trouvera son application dans le domaine de la quincaillerie du bâtiment et a trait aux ferrures de verrouillage du type crémone ou crémone-serrure, en particulier aux gâches équipant de telles crémones.The present invention will find application in the field of building hardware and relates to locking fittings of the type espagnolette or espagnolette-lock, in particular the locks equipping such cremone bolts.

De manière usuelle, il est connu dans le domaine des ferrures de verrouillage, de type crémones ou crémone-serrures, d'équiper la ou les tringles de manoeuvre de ces crémones ou crémones-serrures d'organes de verrouillage sous forme de galets aptes à coopérer avec des gâches de configuration adaptée.In the usual manner, it is known in the field of lock fittings, of the cremone or espagnolette-lock type, to equip the operating rod or rods of these cremones or espagnolette locks of locking members in the form of rollers suitable for cooperate with latches of adapted configuration.

Plus particulièrement, dans une disposition fréquente, ces gâches sont rapportées sur le cadre dormant d'une porte ou fenêtre, tandis que la crémone ou crémone-serrure équipe au moins l'un des ouvrants de cette dernière. Au moment de refermer cette porte-fenêtre, donc en repoussant le ou les vantaux sur le cadre dormant, et en actionnant la crémone ou crémone-serrure, il s'ensuit l'engagement du ou des galets dans leur gâche correspondante sur le dormant. La porte ou fenêtre est alors au moins partiellement refermée.More particularly, in a frequent arrangement, these strikes are reported on the frame of a door or window, while the espagnolette or espagnolette-lock equips at least one of the opening of the latter. When closing the French window, thus pushing the door leaf (s) on the frame, and actuating the espagnolette or espagnolette-lock, it follows the engagement of the roller or rollers in their corresponding lock on the frame. The door or window is then at least partially closed.

Plus précisément, un galet au moins est engagé dans un logement sous forme d'une découpe débouchante, ménagée dans l'embase que comporte une telle gâche. Cette découpe adopte une section en « U » et est délimitée par un fond et deux parois latérales entre lesquelles s'insère le corps du galet.More precisely, at least one roller is engaged in a housing in the form of an opening cutout, formed in the base that includes such a striker. This cutout adopts a "U" section and is delimited by a bottom and two side walls between which the body of the roller is inserted.

Pour améliorer le caractère sécuritaire et favoriser l'accrochage entre l'organe de verrouillage et la gâche, il est assez courant de conférer au galet une section en T, le logement dans la gâche comportant une forme idoine en T. Plus précisément, les parois latérales délimitant le logement dans la gâche, comportent, sur leur bord supérieur, un retour d'accrochage sous lesquels vient s'insérer la tête d'un tel galet en T.To improve the security and promote the attachment between the locking member and the striker, it is quite common to give the roller a T-section, the housing in the keeper having a suitable shape T. More precisely, the side walls delimiting the housing in the striker, comprise, on their upper edge, a return hooking under which is inserted the head of such a roller T.

Grâce à une telle configuration, on comprend que ce galet est maintenu dans sa gâche par rapport à un déplacement à la fois parallèle et perpendiculaire au plan de cette gâche, empêchant tout décrochement.With such a configuration, it is understood that this roller is held in its keeper with respect to a displacement both parallel and perpendicular to the plane of the striker, preventing any recess.

Si, comme cela apparaît au travers de la description qui précède, cette configuration améliore la coopération entre galet et gâche, se pose toutefois la problématique de l'engagement de l'un dans l'autre malgré les nombreux défauts d'ajustement entre ouvrant et dormant d'une menuiserie de type porte ou fenêtre.If, as appears from the foregoing description, this configuration improves the cooperation between roller and striker, however, there is the problem of the engagement of the one in the other despite the numerous defects of adjustment between opening and sleeping carpentry type door or window.

On comprend, en effet, que pour permettre l'engagement d'un tel galet en T dans sa gâche, il convient, lorsque l'ouvrant est refermé sur le dormant, que, non seulement, le galet puisse s'insérer au travers de l'ouverture débouchante dans le logement de la gâche, donc entre les deux parois latérales délimitant ce logement, mais, en outre, que la tête du galet soit positionnée à la bonne hauteur pour pouvoir glisser sous les retours d'accrochage que comportent ces parois latérales.It is understood, indeed, that to allow the engagement of such a T-roller in its striker, it is appropriate, when the door is closed on the frame, that, not only, the roller can be inserted through the opening opening in the housing of the striker, therefore between the two side walls delimiting this housing, but, moreover, that the head of the roller is positioned at the right height to be able to slide under the return hooks that comprise these walls side.

A ce propos, pour compenser les nombreux défauts d'ajustement d'une menuiserie et en particulier pour pallier des déréglages ultérieurs, il est d'ores et déjà prévu des moyens pour régler le positionnement du galet en T par rapport à la tringle de manoeuvre dont il est solidaire. En l'occurrence, ces moyens de réglage permettent, souvent, d'intervenir suivant une direction axiale et transversale sur ce galet en T.In this respect, in order to compensate for the numerous adjustment defects of a joinery and in particular to compensate for subsequent maladjustments, means are already provided for adjusting the positioning of the T-roller with respect to the operating rod. of which he is in solidarity. In this case, these adjustment means allow, often, to intervene in an axial and transverse direction on the roller T.

Le réglage transversal est habituellement obtenu par l'intermédiaire d'un excentrique, tandis que le réglage axial peut découler d'un galet en T de type télescopique, autrement dit un galet constitué des deux parties réglables axialement l'une par rapport à l'autre de manière élastique ou mécanique.The transverse adjustment is usually obtained via an eccentric, while the axial adjustment can arise from a telescopic T-type roller, that is to say a roller consisting of two axially adjustable parts relative to the other elastically or mechanically.

Une autre solution consiste à attribuer cette fonction de réglage à la tringle de manoeuvre elle-même pourvue dudit galet en T. Ainsi, cette tringle de manoeuvre peut être prévue suffisamment élastique pour conférer au galet une mobilité axiale suffisante permettant un ajustement en conséquence par rapport à la gâche lorsqu'intervient le verrouillage.Another solution is to assign this adjustment function to the operating rod itself provided with said T-roller. Thus, this operating rod can be provided sufficiently elastic to give the roller sufficient axial mobility allowing adjustment accordingly with respect to the striker when interlocking.

Comme il ressort de la solution selon l'état de la technique consistant à définir le galet en T sous forme de plusieurs pièces réglables entre elles, celui-ci est de conception particulièrement complexe. A cela, il faut rappeler que de tels galets correspondent à des pièces de très faible dimension, amenées, pour autant, à être fortement sollicitées lors de différentes manoeuvres de verrouillage et de déverrouillage.As is clear from the solution according to the state of the art of defining the T-roller in the form of several parts adjustable between them, it is of particularly complex design. To this, it should be remembered that such rollers correspond to parts of very small size, provided, for all that, to be strongly stressed during different locking and unlocking maneuvers.

De plus, ces galets doivent procurer une résistance à l'arrachement suffisante pour atteindre le degré de sécurité requis pour des ferrures de verrouillage de type crémone ou crémone-serrures.In addition, these rollers must provide a tear resistance sufficient to achieve the degree of security required for espagnolette type locks or espagnolette locks.

Quant à la solution consistant à conférer à la tringle de manoeuvre une élasticité suffisante pour permettre à un galet un ajustement par rapport à sa gâche, ne répond pas davantage aux contraintes dans le domaine. En effet, de telles tringles de manoeuvre sont, elles aussi, amenées à transmettre des efforts conséquents qui requièrent une rigidité suffisante incompatible avec la souplesse que préconise cette solution de l'état de la technique.As for the solution of giving the maneuvering rod sufficient elasticity to allow a roller an adjustment relative to its keeper, does not respond more to the constraints in the field. Indeed, such rods maneuver are also made to transmit significant efforts that require sufficient rigidity incompatible with the flexibility that advocates this solution of the prior art.

Une autre solution, décrite dans le document DE 10 2004 062558 concerne une gâche comportant deux logements débouchant de section en T pour la réception d'un galet de verrouillage en T dans au moins une position de verrouillage. Un tel logement est délimité par un fond d'où s'étendent deux parois latérales sensiblement parallèles terminées, chacune, par un retour d'accrochage. Cette gâche comporte, encore, d'une part, une plaque support définissant le fond de cette gâche et, d'autre part, une lame de recouvrement, pliée en sorte d'adopter une forme en « U », et définissant les retours d'accrochage ainsi que les parois latérales qui comportent des langues de guidage mobiles au travers de la plaque support. Cette gâche comporte, aussi, des moyens pour régler la position des retours d'accrochage par rapport au fond.Another solution, described in the document DE 10 2004 062558 concerns a keeper comprising two housings opening with a T-section for receiving a T-lock roller in at least one locking position. Such a housing is delimited by a bottom from which extend two substantially parallel side walls each terminated by a return hooking. This keeper comprises, on the one hand, a support plate defining the bottom of this striker and, on the other hand, a covering blade, folded so as to adopt a "U" shape, and defining the returns of and the side walls which comprise guiding tongues movable through the support plate. This waste has, also, means for adjusting the position of the return hooks relative to the bottom.

Ces moyens de réglage sont conçus pour régler la distance entre le fond et les rebords d'accrochage et assurent une immobilisation, de manière permanente, de ces rebords d'accrochage à une distance déterminée par rapport à ce fond. Cependant, ces moyens de réglage ne permettent aucunement de remédier aux nombreux défauts d'ajustement entre ouvrant et dormant d'une menuiserie qui, bien que la distance entre les rebords d'accrochage et le fond soit correctement réglée, ont pour effet d'entraver le glissement de la tête du galet sous les rebords d'accrochage de la gâche. Là encore et pour remédier à ces défauts d'ajustement, on confère à la tringle de manoeuvre une élasticité suffisante pour permettre à un galet un ajustement par rapport à sa gâche, ceci avec les mêmes inconvénients que ceux déjà mentionnés ci-dessus.These adjustment means are designed to adjust the distance between the bottom and the hooking edges and ensure a permanent immobilization of these hooking edges at a determined distance relative to this bottom. However, these adjustment means do not make it possible to remedy the many faults of adjustment between opening and frame of a carpentry which, although the distance between the hooking edges and the bottom is properly adjusted, have the effect of hindering the sliding of the head of the roller under the hooking edges of the striker. Again and to remedy these adjustment defects, it gives the drive rod sufficient elasticity to allow a roller adjustment relative to its keeper, with the same disadvantages as those already mentioned above.

C'est dans le cadre d'une première démarche inventive que l'on a imaginé associer, non pas au galet, mais à la gâche, les fonctionnalités d'ajustement nécessaires pour pallier les problématiques d'équerrage et d'ajustement d'un ouvrant de porte ou fenêtre par rapport à son cadre dormant.It is within the framework of a first inventive step that we have imagined associating, not with the roller, but with the waste, the functionalities of adjustment necessary to palliate the problems of squareness and adjustment of a opening door or window relative to its sleeping frame.

De plus, selon l'état de la technique, il est courant, pour diminuer le coût de fabrication d'une gâche avec logement en T de la concevoir, non pas en une seule pièce, mais en deux pièces et, en particulier, une embase et une tôle de recouvrement. Cette conception facilite grandement le moulage sans dépouille de l'embase, tandis que la tôle de recouvrement est conçue par simple emboutissage.In addition, according to the state of the art, it is common to reduce the cost of manufacturing a keeper with T-housing to design it, not in one piece, but in two parts and, in particular, a base and a cover plate. This design greatly facilitates the blankless molding of the base, while the cover plate is designed by simple stamping.

Finalement, c'est dans le cadre d'une autre démarche inventive que la présente invention a su mettre à profit cette conception connue des gâches à galet en T, pour leur conférer des fonctionnalités jusqu'alors associés à un tel galet en T.Finally, it is within the framework of another inventive step that the present invention has been able to take advantage of this known design of T-roller strikes, to give them functionalities hitherto associated with such a T-roller.

A cet effet, l'invention concerne une gâche pour ferrure de verrouillage du type crémone ou crémone-serrure, comportant :

  • au moins un logement débouchant de section en T pour la réception dans au moins une position de verrouillage d'un galet de verrouillage en T, ledit logement étant délimité par au moins un fond d'où s'étendent deux parois latérales sensiblement parallèles terminées, chacune, par un retour d'accrochage ;
  • une lame de recouvrement définissant les retours d'accrochage à l'extrémité opposée au fond des parois latérales.
For this purpose, the invention relates to a latch for a locking fitting of the cremone or espagnolette-lock type, comprising:
  • at least one housing opening with a T-section for receiving in at least one locking position of a roller T-lock, said housing being delimited by at least one bottom from which extend two substantially parallel side walls each terminated by a snap back;
  • a cover blade defining the return hooks at the opposite end to the bottom of the side walls.

Cette gâche est caractérisée par le fait qu'elle comporte des moyens d'ajustement de la distance séparant le fond des retours d'accrochage, lesdits moyens d'ajustement étant constitués par la lame de recouvrement qui est élastiquement déformable.This striker is characterized in that it comprises means for adjusting the distance separating the bottom of the return hooks, said adjustment means being constituted by the cover blade which is elastically deformable.

Une autre caractéristique consiste en ce que la lame de recouvrement s'étend dans un plan et est mobile dans une direction perpendiculaire à ce plan.Another feature is that the cover blade extends in a plane and is movable in a direction perpendicular to this plane.

Une caractéristique additionnelle concerne le fait que la lame de recouvrement, d'une part, s'étend dans un plan parallèle au fond du ou des logements de la gâche, respectivement perpendiculaire aux parois latérales du ou des logements de la gâche et, d'autre part, est mobile dans une direction perpendiculaire à ce fond, respectivement parallèle à ces parois latérales.An additional feature relates to the fact that the cover plate, on the one hand, extends in a plane parallel to the bottom of the housing (s) of the keeper, respectively perpendicular to the side walls of the housing (s) of the keeper and, on the other hand, is movable in a direction perpendicular to this bottom, respectively parallel to these side walls.

Encore une autre caractéristique consiste en ce que ladite lame de recouvrement comporte, au droit du logement, une découpe définissant deux branches élastiques correspondants aux retours d'accrochage aptes à s'écarter par élasticité du fond pour ajuster leur distance par rapport à ce dernier.Yet another feature consists in that said cover blade comprises, at the right of the housing, a cut defining two elastic branches corresponding to the snap returns able to depart by elasticity of the bottom to adjust their distance relative to the latter.

Une caractéristique additionnelle consiste en ce que la gâche comporte, d'une part, une embase pourvue du ou des logements débouchants et comportant le fond ainsi que les parois latérales s'étendant à partir de ce fond et, d'autre part, la lame de recouvrement montée sur ladite embase, ceci de manière mobile.An additional feature is that the striker comprises, on the one hand, a base provided with one or more through-slots and having the bottom and the side walls extending from this bottom and, on the other hand, the blade covering mounted on said base, this movably.

Les avantages découlant de la présente invention consistent, en conférant à la gâche des moyens d'ajustement préalablement associés au galet de verrouillage en T, en une conception de ce dernier bien moins complexe, sans compter qu'il gagne en résistance mécanique.The advantages resulting from the present invention consist, by conferring on the striker adjustment means previously associated with the T-lock roller, a design of the latter much less complex, besides it gains in mechanical strength.

La présente invention permet encore la conception d'une ferrure de verrouillage comportant des tringles de manoeuvre de grande rigidité pour la transmission d'efforts de verrouillage et de déverrouillage plus conséquent.The present invention still allows the design of a locking fitting having high rigidity operating rods for the transmission of locking forces and more important unlocking.

Un autre avantage consiste en ce que les moyens d'ajustement que comporte la gâche conforme à l'invention permettent un ajustement dynamique (plus particulièrement lors des manoeuvres de verrouillage et de déverrouillage) de la distance entre le fond et les rebords d'accrochage, ceci contrairement à un réglage statique et permanent procuré par les moyens de réglage des gâches de l'état de la technique.Another advantage is that the adjustment means that includes the striker according to the invention allow a dynamic adjustment (particularly during the locking and unlocking maneuvers) of the distance between the bottom and the hooking edges, this in contrast to a static and permanent adjustment provided by the latch adjustment means of the state of the art.

Encore un autre avantage consiste en ce que les moyens d'ajustement de la distance séparant le fond des rebords d'accrochage sont constitués par une lame de recouvrement. Le fait de définir des moyens d'ajustement sous la forme d'une telle lame de recouvrement permet, avantageusement, de proposer une gâche de ferrure de verrouillage dont la conception est notablement simplifiée par rapport à celle des gâches de l'état de la technique.Yet another advantage is that the adjustment means of the distance separating the bottom of the attachment flanges are constituted by a cover blade. The fact of defining adjustment means in the form of such a cover plate advantageously makes it possible to propose a lock fitting keeper whose design is considerably simplified compared to that of the strikes of the state of the art. .

De plus, cette lame de recouvrement est élastiquement déformable ce qui permet, avantageusement, d'éviter de recourir à des moyens de rappel additionnels comme pour les gâches de l'état de la technique.In addition, this cover blade is elastically deformable, which advantageously makes it possible to avoid the need for additional return means, such as for the strikes of the state of the art.

Finalement, on observera que les gâches pour ferrures de verrouillage doivent assurer un verrouillage approprié d'un ouvrant sur un dormant. Pour ce faire, ces gâches doivent, en particulier, présenter une haute résistance mécanique à l'effraction (plus particulièrement à l'arrachement comme mentionné ci-dessus). L'homme du métier aurait, donc, naturellement, tendance à réaliser des gâches particulièrement rigides et n'aurait aucunement tendance à envisager un élément élastiquement déformable. Pourtant, de manière avantageuse et surprenante, une telle lame de recouvrement élastiquement déformable permet de conférer à la gâche conforme à l'invention la résistance mécanique nécessaire pour résister à une effraction, ceci en raison du fait que, même si la lame de recouvrement se déforme, celle-ci reste en prise avec le galet et empêche le décrochement de l'ouvrant.Finally, it will be observed that the strikes for locking fittings must ensure proper locking of an opening on a frame. To do this, these locks must, in particular, have a high mechanical resistance to burglary (especially tearing as mentioned above). The person skilled in the art would, therefore, naturally tend to make particularly rigid strikes and would have no tendency to consider an elastically deformable element. However, advantageously and surprisingly, such an elastically deformable covering blade makes it possible to confer on the striker according to the invention the mechanical strength necessary to resist burglary, this because of the fact that, even if the blade of cover deforms, it remains in engagement with the roller and prevents the recess of the opening.

Tel que représenté dans les figures du dessin ci-joint, la présente invention concerne une gâche 1 pour ferrure de verrouillage de type crémone ou crémone-serrure.As shown in the figures of the attached drawing, the present invention relates to a striker 1 for lock fitting type espagnolette or espagnolette-lock.

A titre d'exemple, une telle gâche peut être prévue pour être fixée en feuillure d'un cadre dormant de porte ou fenêtre de manière apte à coopérer avec un organe de verrouillage de type galet en T 2. Une telle coopération intervient sous l'action d'une tringle de manoeuvre 3 correspondant à une crémone ou crémone-serrure et dont est rendu solidaire ce galet en T 2. Ceci a été illustré de manière schématisée, dans la figure 2 du dessin ci-joint.For example, such a striker may be provided to be fixed in a rabbet of a door or window frame so as to cooperate with a T-type roller member 2. Such cooperation occurs under the action of an operating rod 3 corresponding to a cremone or espagnolette-lock and which is secured to this roller T 2. This has been illustrated schematically in the figure 2 from the drawing attached.

Ainsi, cette gâche 1 comporte une embase 4 comportant des moyens 5 lui permettant de coopérer avec la menuiserie en vue de sa fixation sur cette dernière. A titre d'exemple, une telle embase 4 peut être pourvue, au niveau de sa partie inférieure, d'un sabot 6 au travers duquel la gâche 1 peut être ancrée dans une rainure de section adaptée aménagée en feuillure de cette menuiserie. En outre, ces moyens de fixation 5 peuvent être complétés par une ou plusieurs ouvertures 7 de passage d'une vis de fixation, d'un rivet ou similaire.Thus, this striker 1 comprises a base 4 having means 5 enabling it to cooperate with the joinery in order to fix it on the latter. For example, such a base 4 may be provided, at its lower part, a shoe 6 through which the striker 1 can be anchored in a groove of suitable section fitted rabbet of this joinery. In addition, these fastening means 5 may be completed by one or more openings 7 for the passage of a fastening screw, a rivet or the like.

Cette gâche 1 comporte encore au moins un logement débouchant (8, 8A), de section en T pour la réception, dans au moins une position de verrouillage, d'un tel galet en T 2. Dans les exemples de réalisation illustrés dans les figures du dessin ci-joint, la gâche 1 comporte, de manière symétrique par rapport à un plan médian transversal 9, deux logements (8, 8A) avec, chacun, une extrémité débouchante (10, 11).This striker 1 further comprises at least one opening opening (8, 8A), T-section for receiving, in at least one locking position, such a roller T 2. In the embodiments shown in the figures attached drawing, the strike 1 comprises, symmetrically with respect to a transverse median plane 9, two housings (8, 8A) each with a through end (10, 11).

Un tel logement (8, 8A) est délimité par au moins un fond 12 d'où s'étendent des parois latérales de guidage (13, 14), plus particulièrement sensiblement parallèles, se terminant, chacune, par un retour d'accrochage (15, 16), plus particulièrement en bordure opposée au fond 12.Such a housing (8, 8A) is delimited by at least one bottom 12 from which lateral guiding walls (13, 14) extend, more particularly substantially parallel, each terminating in a hooking back ( 15, 16), more particularly at the edge opposite the bottom 12.

Comme l'indique sa dénomination, le galet en T 2 comporte une tige ou rouleau 17 dont une extrémité est rendue solidaire de la tringle de manoeuvre 3 et dont l'extrémité opposée 18 se termine par un flasque 19. Celui-ci est de section 20 plus importante que la section 21 de ladite tige ou rouleau 17 de manière à définir, le long de ce galet 2, un décrochement 22 qui, en coopération avec les retours d'accrochage (15, 16), empêche le dégagement du galet en T 2 de la gâche 1, dans une direction axiale 28 audit galet 2, donc perpendiculaire au plan de la gâche 1.As indicated by its name, the roller T 2 comprises a rod or roller 17 whose one end is secured to the operating rod 3 and whose opposite end 18 ends with a flange 19. This is section 20 greater than the section 21 of said rod or roller 17 so as to define, along the roller 2, a recess 22 which, in cooperation with the return hooks (15, 16), prevents the release of the roller in T 2 of the striker 1, in an axial direction 28 to said roller 2, thus perpendicular to the plane of the striker 1.

Contrairement, la largeur de passage 23, délimitée entre les retours d'accrochage (15, 16), est, elle, ajustée à la section 21 de la tige 17 du galet en T 2 pour permettre l'engagement de ce dernier dans le logement (8, 8A), depuis l'extrémité débouchante 10, respectivement 11. En outre, la distance séparant les parois latérales de guidage (13, 14) est déterminée au moins égale à la section 20 du flasque 19 terminant le galet en T 2.In contrast, the passage width 23 delimited between the return hooks (15, 16) is adjusted to the section 21 of the rod 17 of the T-roller 2 to allow engagement of the latter in the housing. (8, 8A), from the emergent end 10, respectively 11. In addition, the distance separating the lateral guide walls (13, 14) is determined at least equal to the section 20 of the flange 19 terminating the T-roller 2 .

A noter, encore, qu'à hauteur de cette extrémité débouchante (10, 11) du logement (8, 8A), lesdites parois latérales de guidage (13, 14) vont en s'évasant pour faciliter l'engagement dudit galet en T 2.It should also be noted that, at the level of this emergent end (10, 11) of the housing (8, 8A), said lateral guide walls (13, 14) flare out to facilitate engagement of said T-roller. 2.

De même et comme visible dans la figure 2, au niveau de cette extrémité débouchante (10, 11) d'un logement (8, 8A), les retours d'accrochage (15, 16) comportent, préférentiellement, un chanfrein d'engagement 24 ayant pour objectif, en coopération avec le galet en T 2, de favoriser l'engagement du flasque 19 sous ces retours d'accrochage (15, 16).Similarly and as visible in the figure 2 , at this emergent end (10, 11) of a housing (8, 8A), the return hooks (15, 16) comprise, preferably, an engagement chamfer 24 for the purpose, in cooperation with the T-roller 2, to promote the engagement of the flange 19 under these return hooks (15, 16).

Justement, pour compenser les défauts d'équerrage au niveau de la menuiserie résultant des tolérances de fabrication ou d'affaissement en cours d'usage, la gâche 1 comporte, selon l'invention, des moyens d'ajustement 25 de la distance 26 séparant le fond 12 d'un logement (8, 8A) des retours d'accrochage (15, 16).In fact, to compensate for squareness defects in the joinery resulting from manufacturing or sagging tolerances in use, the striker 1 comprises, according to the invention, means 25 for adjusting the distance 26 separating the bottom 12 of a housing (8, 8A) return hooking (15, 16).

De manière substantielle, ces retours d'accrochage (15, 16), définis à l'extrémité opposée au fond 12 des parois latérales de guidage (13, 14), sont délimités par une lame de recouvrement 27. En fait, cette lame de recouvrement 27 définit les retours d'accrochage (15, 16), ceci à l'extrémité opposée au fond 12 des parois latérales de guidage (13, 14), plus particulièrement au-dessus de ces parois latérales de guidage (13, 14).Substantially, these return hooks (15, 16), defined at the end opposite the bottom 12 of the lateral guide walls (13, 14), are delimited by a cover blade 27. In fact, this blade of overlap 27 defines the return hooks (15, 16), this at the end opposite the bottom 12 of the lateral guide walls (13, 14), more particularly above these lateral guide walls (13, 14). .

Une autre caractéristique de l'invention consiste en ce que cette lame de recouvrement 27 est élastiquement déformable.Another feature of the invention is that this cover blade 27 is elastically deformable.

Tel que mentionné ci-dessus, la gâche 1 selon l'invention comporte des moyens d'ajustement 25de la distance 26 séparant le fond 12 d'un logement (8, 8A) des retours d'accrochage (15, 16). Selon l'invention, ces moyens d'ajustement 25 sont constitués par une telle lame de recouvrement 27 élastiquement déformable.As mentioned above, the keeper 1 according to the invention comprises adjustment means 25de the distance 26 separating the bottom 12 of a housing (8, 8A) of the return hooks (15, 16). According to the invention, these adjustment means 25 are constituted by such a resiliently deformable cover blade 27.

Une autre caractéristique consiste en ce que cette lame de recouvrement 27 est mobile.Another feature is that this cover blade 27 is movable.

A ce propos, on observera que ladite lame de recouvrement 27 s'étend dans un plan et est, alors, mobile dans une direction 28 perpendiculaire à ce plan.In this regard, it will be observed that said cover blade 27 extends in a plane and is then movable in a direction 28 perpendicular to this plane.

Tel que mentionné ci-dessus, la gâche 1 comporte un fond 12 et des parois latérales (13, 14).As mentioned above, the keeper 1 comprises a bottom 12 and side walls (13, 14).

Aussi et selon une autre caractéristique, ladite lame de recouvrement 27 s'étend dans un plan parallèle au fond 12 du ou des logements (8, 8A) de la gâche 1, respectivement perpendiculaire aux parois latérales (13, 14) du ou des logements (8, 8A) de la gâche 1. Dans un pareil cas, ladite lame de recouvrement 27 est mobile dans une direction 28 perpendiculaire à ce fond 12, respectivement parallèle à ces parois latérales (13, 14).Also and according to another characteristic, said cover blade 27 extends in a plane parallel to the bottom 12 of the housing (8, 8A) of the striker 1, respectively perpendicular to the side walls (13, 14) of the housing or (8, 8A) of the striker 1. In such a case, said cover plate 27 is movable in a direction perpendicular to this bottom 12, respectively parallel to these side walls (13, 14).

En somme, cette lame de recouvrement 27 est montée mobile dans une direction 28 parallèle à l'axe du galet en T 2. Cette direction 28 est, par ailleurs, perpendiculaire au plan de la gâche 1.In sum, this cover blade 27 is mounted to move in a direction 28 parallel to the axis of the roller T 2. This direction 28 is, moreover, perpendicular to the plane of the keeper 1.

Tout particulièrement, selon un premier mode de réalisation visible dans la figure 1, cette mobilité de la lame de recouvrement 27 dans la direction 28 de manière à définir les moyens d'ajustement 25 résulte du caractère élastique de cette lame de recouvrement 27.In particular, according to a first embodiment visible in the figure 1 this mobility of the cover blade 27 in the direction 28 so as to define the adjustment means 25 results from the elastic nature of this cover blade 27.

Dans ce mode de réalisation illustré dans la figure 1, ladite lame de recouvrement 27 comporte, au droit du logement (8, 8A), une découpe 29 de largeur 23 ajustée à la tige ou rouleau 17 du galet en T 2. Cette découpe 29 définit au niveau de cette lame de recouvrement 27 deux branches élastiques (31, 31A) correspondants aux retours d'accrochage (15, 16) aptes à s'écarter par élasticité du fond 12 pour ajuster leur distance par rapport à ce dernier 12. Cette découpe 29 va, là encore, en s'évasant à hauteur de l'extrémité débouchante (10, 11) de ce logement (8, 8A).In this embodiment illustrated in the figure 1 said covering blade 27 comprises, at the right of the housing (8, 8A), a cutout 29 of width 23 fitted to the rod or roller 17 of the T-roller 2. This cutout 29 defines at the level of this cover blade 27 two elastic branches (31, 31A) corresponding to the return hooks (15, 16) able to depart elastically from the bottom 12 to adjust their distance relative to the latter 12. This cutout 29 goes, again, in s' flaring at the open end (10, 11) of this housing (8, 8A).

Tel que mentionné ci-dessus, ladite gâche 1 comporte une embase 4. En fait, cette embase 4 est pourvue du ou des logements débouchants (8 ; 8A) et comporte le fond 12 ainsi que les parois latérales (13, 14) s'étendant à partir de ce fond 12.As mentioned above, said striker 1 comprises a base 4. In fact, this base 4 is provided with one or more through-holes (8; 8A) and comprises the bottom 12 as well as the side walls (13, 14). extending from this bottom 12.

Tel que visible sur les figures en annexe, cette embase 4 est constituée par une pièce (plus particulièrement monobloc) adoptant une forme en « U » et comportant le fond 12 ainsi que les parois latérales (13, 14) s'étendant à partir de ce fond 12.As can be seen in the appended figures, this base 4 is constituted by a part (more particularly one-piece) adopting a "U" shape and comprising the bottom 12 and the side walls (13, 14) extending from this bottom 12.

Aussi et selon une caractéristique additionnelle de l'invention, la lame de recouvrement 27 est montée sur ladite embase 4, ceci de manière mobile.Also and according to an additional feature of the invention, the cover blade 27 is mounted on said base 4, this movably.

En fait, cette lame de recouvrement 27 est rapportée, de manière mobile, par-dessus ladite embase 4, plus particulièrement par-dessus les parois latérales (13, 14) que comporte cette embase 4.In fact, this cover blade 27 is movably attached over said base 4, more particularly over the side walls (13, 14) that this base 4 comprises.

Tel que mentionné ci-dessus, ladite lame de recouvrement 27 est montée mobile sur ladite embase 4, une telle mobilité étant, alors, dans une direction 28 perpendiculaire au fond 12 de l'embase 4, respectivement parallèle aux parois latérales (13, 14) de cette embase 4.As mentioned above, said cover blade 27 is movably mounted on said base 4, such a mobility being, then, in a direction perpendicular to the base 12 of the base 4, respectively parallel to the side walls (13, 14 ) of this base 4.

A l'extrémité opposée 30 de l'extrémité débouchante (10, 11) du ou des logements (8, 8A), soit au centre de la gâche 1 dans le mode de réalisation illustré, cette lame de recouvrement 27 est rendue solidaire de l'embase 4, plus particulièrement par sertissage, rivetage, vissage ou analogue. Ainsi, par élasticité à ladite extrémité débouchante (10, 11) du logement (8, 8A), les deux branches élastiques (31, 31A), s'étendant de part et d'autre de la découpe 21, sont susceptibles de s'écarter du fond 12, conduisant à un ajustement en distance par rapport à ce dernier des retours d'accrochage (15, 16) que définissent lesdites deux branches élastiques (31, 31A).At the opposite end 30 of the open end (10, 11) of the housing or slots (8, 8A), either in the center of the striker 1 in the illustrated embodiment, this cover blade 27 is secured to the base 4, more particularly by crimping, riveting, screwing or the like. Thus, by elasticity at said emergent end (10, 11) of the housing (8, 8A), the two elastic branches (31, 31A), extending on either side of the cutout 21, are capable of away from the bottom 12, leading to a distance adjustment with respect thereto retaining returns (15, 16) defined by said two elastic branches (31, 31A).

Dans un second mode de réalisation visible dans les figures 3, 4, 5 et 6, ladite lame de recouvrement 27 est montée mobile en translation selon la direction 28 sur l'embase 4 de la gâche 1.In a second embodiment visible in the figures 3 , 4, 5 and 6 said covering blade 27 is mounted to move in translation in the direction 28 on the base 4 of the striker 1.

Tout particulièrement, cette lame de recouvrement 27 comporte, au niveau de ses chants latéraux 32, 32A, des rebords d'accrochage en C (33, 33A), venant s'engager dans des rainures d'accrochage adaptées (34, 34A), que comporte au niveau de ses côtés latéraux (35, 35A), ladite embase 4.In particular, this cover blade 27 comprises, at its side edges 32, 32A, C hooking flanges (33, 33A), engaging in suitable latching grooves (34, 34A), which comprises at its lateral sides (35, 35A), said base 4.

Par ailleurs, ces rebords d'accrochage en C (33, 33A), viennent coopérer avec lesdites rainures d'accrochage (34, 34A), avec une mobilité dans la direction 28 selon une course 36 prédéfinie. D'ailleurs, un dispositif de réglage 37 adapté permet à l'usager d'ajuster le positionnement de la lame de recouvrement 27 par rapport à l'embase 4, le long de la course 36.Moreover, these C-hooking flanges (33, 33A) cooperate with said hooking grooves (34, 34A), with a mobility in the direction 28 according to a predefined stroke 36. Moreover, an adapted adjustment device 37 allows the user to adjust the positioning of the cover blade 27 with respect to the base 4, along the path 36.

Ce réglage peut intervenir contre l'action de moyens de rappel élastique 38 tendant à repousser ladite lame de recouvrement 27 dans l'une ou l'autre des positions extrêmes de cette course 36.This adjustment can intervene against the action of elastic return means 38 tending to push said cover blade 27 in one or other of the extreme positions of this race 36.

Dans le mode de réalisation représenté dans les figures 3 à 6 du dessin ci-joint, ces moyens de rappel élastique 38 sous forme de lames élastiques 39 ménagées au niveau des rainures d'accrochage (34, 34A), tendent à repousser la lame de recouvrement 27 en applique sur l'embase 4, donc en extrémité de course 36 conduisant à la distance 26 la plus réduite entre le fond 12 et les retours d'accrochage (15, 16).In the embodiment shown in Figures 3 to 6 of the attached drawing, these elastic return means 38 in the form of resilient blades 39 formed at the hooking grooves (34, 34A), tend to push the cover blade 27 to apply to the base 4, so in race end 36 leading to the smallest distance 26 between the bottom 12 and the return hooks (15, 16).

Pour en revenir au dispositif de réglage 37, celui-ci peut être défini, par exemple, par un excentrique 40 se présentant saillant au niveau du ou des chants latéraux (32, 32A) de l'embase 4, ceci au travers d'une lumière oblongue 41 au niveau des rebords d'accrochage en C (33, 33A), lumière oblongue 41 s'étendant parallèlement à la direction 28. Ainsi, en agissant sur l'excentrique 40, il est possible de repousser la lame de recouvrement 27 dans une direction opposée à l'embase 4 ceci contre l'action des moyens de rappel élastique 38 pour ajuster la distance 26.To return to the adjusting device 37, it can be defined, for example, by an eccentric 40 which is projecting at the level of the lateral edges (32, 32A) of the base 4, this through a oblong slot 41 at the level of the fastening flanges C (33, 33A), oblong slot 41 extending parallel to the direction 28. Thus, by acting on the eccentric 40, it is possible to push the cover blade 27 in a direction opposite to the base 4 this against the action of the elastic return means 38 to adjust the distance 26.

Il convient cependant d'observer lorsqu'intervient l'engagement dans un logement (8, 8A) d'un galet en T 2, sous l'impulsion du flasque 19 de ce dernier, cette lame de recouvrement 27 peut encore être amenée à s'écarter davantage de l'embase 4, ceci dans la limite de la course 36 autorisée.However, it should be observed when the engagement into a housing (8, 8A) of a roller T 2, under the influence of the flange 19 of the latter, this cover blade 27 can still be brought to s further away from the base 4, this within the limit of the authorized race 36.
