Description

L'invention est relative à une plaque pour poignée de porte qui trouvera notamment son application comme élément d'ornement dans les habitations domestiques.The invention relates to a plate for a door handle which will find its application in particular as an ornamental element in domestic dwellings.

On connait traditionnellement le rôle des plaques pour poignée de porte qui servent à des fins décoratives et par ailleurs à protéger la peinture des portes contre les traces de doigts.We traditionally know the role of door handle plates which are used for decorative purposes and also to protect the paint on doors against fingerprints.

Le style de la plaque va de pair avec celui de la poignée pour former un ensemble harmonieux. La plaque est percée d'un orifice pour permettre le passage du carré de manoeuvre qui relie la poignée au mécanisme de serrurerie encastré dans la porte.The style of the plate goes hand in hand with that of the handle to form a harmonious whole. The plate is pierced with an orifice to allow the passage of the operating square which connects the handle to the locksmith mechanism embedded in the door.

La rotation de la poignée actionne le déplacement longitudinal du pêne qui rentre dans la serrure et permet ainsi l'ouverture de la porte. Une serrure comprend généralement deux ressorts, le premier s'applique directement sur le pêne pour le pousser en position sortie. Ce ressort est actionné seul lorsque l'on claque la porte sans manoeuvrer la poignée. Il permet de pouvoir rentrer le pêne dans la serrure par simple pression extérieure.The rotation of the handle activates the longitudinal movement of the bolt which enters the lock and thus allows the door to be opened. A lock generally comprises two springs, the first is applied directly to the bolt to push it into the extended position. This spring is actuated alone when the door is slammed without maneuvering the handle. It allows the bolt to be retracted into the lock by simple external pressure.

Le second ressort présent dans la serrure s'applique sur le carré de manoeuvre pour provoquer le rappel de la poignée en l'absence de contraintes de rotation extérieures. Ce second ressort permet notamment qu'en cas d'actionnement du pêne seul, il ne se produise pas une rotation correspondante de la poignée.The second spring present in the lock is applied to the operating square to cause the return of the handle in the absence of external rotation constraints. This second spring allows in particular that in the event of actuation of the bolt alone, a corresponding rotation of the handle does not occur.

On peut distinguer principalement deux types de poignée de porte, celles qui présentent une parfaite symétrie de construction du type boule et celles qui, au contraire, sont déséquilibrées par la présence d'un bras latéral.We can mainly distinguish two types of door handle, those which have a perfect symmetry of construction of the ball type and those which, on the contrary, are unbalanced by the presence of a lateral arm.

Les poignées symétriques ne présentent guère de difficulté d'emploi. Par contre, en ce qui concerne les poignées dissymétriques, plus couramment utilisées, elles présentent, de par nature, un déséquilibre pesant important. Par exemple, certaines répliques d'anciennes poignées sont massives et réalisées en métal, donc avec un porte-à-faux conséquent.The symmetrical handles hardly present any difficulty of use. On the other hand, with regard to the asymmetrical handles, which are more commonly used, they present, by nature, a significant heavy imbalance. For example, some replicas of old handles are massive and made of metal, so with a substantial overhang.

Ce type de poignée fatigue très vite le ressort de rappel de la serrure et rapidement, le couple de basculement résultant de la présence d'une poignée pesante dissymétrique suffit à empêcher la sortie du pêne et la porte ne se ferme plus.This type of handle quickly tires the return spring of the lock and quickly, the tilting torque resulting from the presence of a heavy asymmetrical handle is enough to prevent the bolt from coming out and the door no longer closes.

La fabrication des serrures s'est standardisée et a été conçue pour répondre aux exigences d'utilisation avec une poignée légère. Tout excès à ce niveau se traduit par une dégradation prématurée de la serrure.The manufacture of locks has been standardized and has been designed to meet the requirements of use with a handle slight. Any excess at this level results in premature degradation of the lock.

Le but principal de la présente invention est de présenter une plaque pour poignée de porte qui puisse être utilisée avec tous type de poignée, en particulier, celles présentant un déséquilibre pesant important sans que cette présence ait des répercussions négatives sur le ressort de rappel de la serrure.The main object of the present invention is to present a plate for a door handle which can be used with any type of handle, in particular those having a significant heavy imbalance without this presence having any negative repercussions on the return spring of the lock.

La plaque de l'invention permet de soulager le ressort de rappel de la serrure et de le prolonger durablement.The plate of the invention makes it possible to relieve the return spring of the lock and to extend it durably.

Un autre but de la présente invention est de présenter une plaque pour poignée de porte polyvalente. En effet, la plaque de l'invention peut s'appliquer sans modification sur une porte s'ouvrant à droite ou à gauche. De plus, elle s'adapte en fonction du couple à contrebalancer. La présence de la plaque de l'invention ne rend pas plus difficile le manoeuvre de la poignée et sa mise en place ne nécessite aucune transformation de la porte.Another object of the present invention is to present a plate for a multipurpose door handle. Indeed, the plate of the invention can be applied without modification to a door opening to the right or to the left. In addition, it adapts according to the torque to be counterbalanced. The presence of the plate of the invention does not make it more difficult to operate the handle and its installation does not require any transformation of the door.

Par ailleurs, certaines serrures usagées pourront être prolongées grâce à la mise en place d'une plaque de porte selon la présente invention.Furthermore, some used locks may be extended by the installation of a door plate according to the present invention.

D'autres buts et avantages de la présente invention apparaitront au cours de la description qui va suivre qui n'est cependant donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is however given only for information and which is not intended to limit it.

Selon l'invention, la plaque pour poignée de porte, destinée à être associée à un mécanisme de serrurerie pour assurer la manoeuvre du pêne de fermeture par rotation de la dite poignée, cette dernière étant susceptible de présenter un déséquilibre pesant important, est caractérisée par le fait que la plaque dispose de moyens de compensation intégrés qui assurent le rappel de la poignée.According to the invention, the plate for the door handle, intended to be associated with a locksmith mechanism for ensuring the operation of the closing bolt by rotation of the said handle, the latter being liable to present a significant heavy imbalance, is characterized by the fact that the plate has integrated compensation means which ensure the return of the handle.

L'invention sera mieux comprise à la lecture de la description suivante accompagnée de dessins en annexe parmi lesquels:

  • - la figure 1 illustre une porte équipée d'une poignée, plaque et mécanisme de serrurerie associés,
  • - la figure 2 schématise la liaison en rotation de la poignée avec le mécanisme de serrurerie,
  • - la figure 3 représente la vue arrière de la plaque pour poignée de porte selon une mode préférentiel de réalisation de l'invention,
  • - la figure 4 illustre en vue de coupe la plaque pour poignée de porte de la figure 3.
The invention will be better understood on reading the following description accompanied by attached drawings, among which:
  • FIG. 1 illustrates a door fitted with a handle, plate and associated locksmith mechanism,
  • - Figure 2 shows diagrammatically the rotation connection of the handle with the locksmith mechanism,
  • FIG. 3 represents the rear view of the plate for a door handle according to a preferred embodiment of the invention,
  • FIG. 4 illustrates in section view the plate for the door handle of FIG. 3.

La présente invention vise une plaque pour poignée de porte qui trouvera notamment son application comme élément décoratif d'intérieur d'habitation domestique.The present invention relates to a plate for a door handle which will find its application in particular as a decorative element for the interior of a domestic dwelling.

La manoeuvre des mécanismes de serrurerie, destinées à assurer la fermeture des portes, est réalisée traditionnellement au moyen d'une poignée dont la manoeuvre assure un mouvement de rotation.The operation of the locks mechanisms, intended to ensure the closing of the doors, is traditionally carried out by means of a handle, the operation of which ensures a rotational movement.

La plaque pour poignée de port joue un rôle décoratif et également un rôle de protection de la porte. La plaque est percée d'un orifice traversé par le carré de manoeuvre reliant la poignée au mécanisme de serrurerie.The door handle plate plays a decorative role and also a protective role for the door. The plate is pierced with an orifice traversed by the operating square connecting the handle to the locksmith mechanism.

Ce mécanisme de serrurerie comprend généralement deux ressorts, le premier d'entre eux s'appliquant directement sur le pêne afin de la pousser en position sortie. Le second ressort s'applique sur le carré de manoeuvre pour assurer le rappel de la poignée.This locksmithing mechanism generally comprises two springs, the first of which is applied directly to the bolt in order to push it into the extended position. The second spring is applied to the operating square to ensure the return of the handle.

Lorsque la poignée mise en place présente un déséquilibre pesant important qui engendre un couple permanent au niveau de la serrure, on assiste à une usure prématurée du ressort de rappel. Celui-ci devient insuffisant pour assurer le retour de la poignée et la serrure doit être changée.When the handle installed has a significant heavy imbalance which generates permanent torque at the lock, there is premature wear of the return spring. This becomes insufficient to ensure the return of the handle and the lock must be changed.

La figure 1 représente une porte 1 équipée d'une poignée 2 de manoeuvre, d'une serrure 3 intégrée dans le champ de la porte 1, la dite serrure présentant au moins un pêne 4.FIG. 1 shows a door 1 fitted with a handle 2 for maneuvering, with a lock 3 integrated in the field of door 1, said lock having at least one bolt 4.

La plaque 5, fixée sur la porte 1, est interposée entre la poignée 2 et le mécanisme 3 de serrurerie.The plate 5, fixed on the door 1, is interposed between the handle 2 and the locksmith mechanism 3.

La figure 2 représente en coupe partielle la liaison établie entre le mécanisme de serrurerie 3 et la poignée de manoeuvre 2. Il s'agit traditionnellement d'un carré de manoeuvre 6 emmanché dans la poignée 2 à laquelle il est fixé axialement par l'intermédiaire d'une goupille 7. D'autres types de liaison peuvent également être envisagés sans pour autant sortir du cadre de la présente invention en particulier, l'utilisation d'une liaison présentant une section de profil différente peut parfaitement être envisagée.Figure 2 shows in partial section the connection established between the locksmith mechanism 3 and the operating handle 2. It is traditionally a maneuvering square 6 fitted in the handle 2 to which it is fixed axially by means of of a pin 7. Other types of connection can also be envisaged without departing from the scope of the present invention in particular, the use of a connection having a section of different profile can perfectly well be envisaged.

Le carré 6 tranverse la plaque 5 par un orifice 8 percé à cet effet. La plaque 5 est directement fixée sur la porte 1 en général par l'intermédiaire de vis non illustrées.The square 6 crosses the plate 5 through an orifice 8 drilled for this purpose. The plate 5 is directly fixed on the door 1 in general by means of screws not shown.

Selon la caractéristique principale de la présente invention, la plaque 5 dispose de moyens de compensation intégrés qui assurent le rappel de la poignée 2.According to the main characteristic of the present invention, the plate 5 has integrated compensation means which ensure the return of the handle 2.

Ces moyens de compensation soulagent la serrure et d'autre part permettent l'utilisation d'une poignée présentant un déséquilibre pesant important sans risque d'endommagement du mécanisme de serrurerie.These compensation means relieve the lock and on the other hand allow the use of a handle having a significant heavy imbalance without risk of damage to the lock mechanism.

En effet, la plaque permet de compenser le poignées sont réalisées en métaux massifs avec un porte-à-faux couple résultant de la présence d'une poignée dissymétrique. Le moment tournant engendré par le poids de la poignée est intégralement neutralisé au niveau de la serrure par la présence de la plaque de l'invention.Indeed, the plate makes it possible to compensate for the handles are made of solid metals with a cantilever torque resulting from the presence of an asymmetrical handle. The turning moment generated by the weight of the handle is completely neutralized at the level of the lock by the presence of the plate of the invention.

Plus précisément, les moyens de compensation permettent d'exercer un couple de rappel ajustable sur la poignée. Dans ces conditions, en fonction des circonstances, on ajuste la compensation pour neutraliser très exactement le moment des forces occasionnées par la présence de la poignée. De ce fait, l'ouverture de la porte par rotation de la poignée ne nécessite aucun effort supplémentaire.More specifically, the compensation means make it possible to exert an adjustable return torque on the handle. Under these conditions, depending on the circumstances, the compensation is adjusted to very precisely neutralize the moment of the forces caused by the presence of the handle. Therefore, the opening of the door by rotation of the handle requires no additional effort.

Selon l'invention, les moyens de compensation se présentent sous la forme d'un organe élastique placé dans un logement réalisé dans la plaque 5 sur laquelle il est fixé et qui est solidaire en rotation du carré de manoeuvre.According to the invention, the compensation means are in the form of an elastic member placed in a housing produced in the plate 5 on which it is fixed and which is integral in rotation with the operating square.

Les figures 3 et 4 représentent respectivement l'envers de la plaque pour poignée de porte selon la présente invention et la plaque en vue de coupe. Le logement 9 pratiqué sur l'envers de la plaque 5 est destiné à recevoir l'organe élastique 10 illustré en pointillé à la figure 3. De préférence, l'organe élastique 10 se présente sous la forme d'un ressort spirale.Figures 3 and 4 respectively show the back of the plate for door handle according to the present invention and the plate in sectional view. The housing 9 formed on the back of the plate 5 is intended to receive the elastic member 10 illustrated in dotted lines in FIG. 3. Preferably, the elastic member 10 is in the form of a spiral spring.

La spire centrale du ressort spirale 10 présente un profil carré qui lui permet de s'adapter autour du carré de manoeuvre 6. Pour la mise en place du carré 6, on fiat coulisser ce dernier dans la spire centrale et on introduit le carré 6 dans la serrure 3. L'immobilisation en rotation est assurée grâce au profil complémentaire de la spire centrale.The central turn of the spiral spring 10 has a square profile which allows it to adapt around the operating square 6. For the establishment of the square 6, it was necessary to slide the latter in the central turn and the square 6 is introduced into the lock 3. The immobilization in rotation is ensured thanks to the complementary profile of the central turn.

Le logement 9 est ouvert sur l'envers de la plaque 5, toutefois, lorsque celle-ci est fixée sur la porte 1, le logement 9 est fermé par la porte et l'organe élastique 10 est immobilisé dans le logement 9.The housing 9 is open on the back of the plate 5, however, when the latter is fixed on the door 1, the housing 9 is closed by the door and the elastic member 10 is immobilized in housing 9.

L'extrémité extérieure du ressort spirale 10 est immobilisée dans une rainure 11 pratiquée dans la plaque 5. Ainsi, le ressort 10 est immobilisé en rotation par rapport à la plaque 5. De préférence, on réalise plusieurs rainures 11 à la périphérie du logement 9 pour pouvoir adjuster le couple de rappel exercé par le ressort 10. Selon les besoins, l'extrémité du ressort 10 est placée dans l'une ou l'autre rainure 11 de telle sorte qu'une fois le carré de manoeuvre 6 introduit dans la spire centrale du ressort 10 et dans la serrure 3, il résulte un couple de rappel adapté au poids de la poignée 2.The outer end of the spiral spring 10 is immobilized in a groove 11 formed in the plate 5. Thus, the spring 10 is immobilized in rotation relative to the plate 5. Preferably, several grooves 11 are produced at the periphery of the housing 9 to adjust the return torque exerted by the spring 10. As required, the end of the spring 10 is placed in one or the other groove 11 so that once the operating square 6 introduced into the central turn of the spring 10 and in the lock 3, there results a return torque adapted to the weight of the handle 2.

Il est également prévu de pouvoir retourner le ressort 10 dans son logement 9 afin d'assurer un sens de rotation du mouvement de rappel soit positif ou négatif selon que la plaque est disposée sur une porte ouvrant à droite ou à gauche.It is also planned to be able to return the spring 10 in its housing 9 in order to ensure a direction of rotation of the return movement either positive or negative depending on whether the plate is disposed on a door opening to the right or to the left.

Il est souhaitable que les dimensions du logement 10 soient légèrement inférieures à celles du ressort spirale 10 au repos. De la sorte, le ressort 10 doit être légèrement comprimé pour être mis en place dans le logement 9 et il se coince dans ce logement 9 sans qu'il puisse tomber.It is desirable that the dimensions of the housing 10 are slightly smaller than those of the spiral spring 10 at rest. In this way, the spring 10 must be slightly compressed to be placed in the housing 9 and it gets stuck in this housing 9 without it being able to fall.

Avantageusement, le logement 9 présente une section circulaire et comporte deux rainures tangentielles 11 et 12 telles qu'illustrées à la figure 3.Advantageously, the housing 9 has a circular section and has two tangential grooves 11 and 12 as illustrated in FIG. 3.

La plaque pourra être réalisée dans différents matéraux en particulier un métal noble usiné.The plate can be made of different materials, in particular a machined noble metal.

Sur un plan esthétique, il est possible de mettre en place les moyens de l'invention sur une plaque de faible épaisseur et par conséquent, il n'y a pas un alourdissement des formes occasionnées par la mise en place des moyens de compensation. Vu de l'extérieur, le logement 9 n'est pas apparent et donc l'aspect de la plaque de l'invention est en tous points identique aux plaques traditionnelles.On an aesthetic level, it is possible to set up the means of the invention on a thin plate and therefore, there is no increase in the forms caused by the establishment of the compensation means. Seen from the outside, the housing 9 is not visible and therefore the appearance of the plate of the invention is identical in all respects to traditional plates.

D'autres mises en oeuvre de la présente invention, à la portée de l'Homme de l'Art, auraient également pu être envisagées sans pour autant sortir du cadre de celle-ci.Other implementations of the present invention, within the reach of ordinary skill in the art, could also have been envisaged without departing from the scope thereof.
