Description

Dispositif d'assistance à l'ouverture ou a la fermeture d'un battant de porte
L'invention concerne un dispositif d'assistance à l'ouverture ou à la fermeture d'un battant de porte.
Assistance device for opening or closing a door leaf
The invention relates to a device for assisting with the opening or closing of a door leaf.

I1 peut être nécessaire pour certaines applications de disposer d'un dispositif d'assistance qui aide l'utilisateur à ouvrir ou fermer une porte dure sans toutefois réaliser de blocage positif. It may be necessary for certain applications to have an assistance device which helps the user to open or close a hard door without however achieving positive blocking.

C'est le cas notamment pour des portes de cages de
Faraday où le frottement d'un couteau sur des contacts élastiques entraîne une résistance qui rend appréciable ladite assistance.
This is particularly the case for cage doors of
Faraday where the friction of a knife on elastic contacts leads to resistance which makes said assistance appreciable.

Le but de l'invention est de proposer un tel dispositif d'assistance. The object of the invention is to propose such an assistance device.

Selon l'invention, ce but est atteint grâce à un système qui comporte deux galets à la périphérie d'un disque monté rotatif sur le battant et pourvu d'un moyen de manoeuvre, ces deux galets pouvant coopérer, sélectivement en fonction de la manoeuvre du disque, avec l'une ou l'autre de deux rampes respectives d'écartement ou de rapprochement du battant montées sur le dormant de la porte. According to the invention, this object is achieved by a system which comprises two rollers at the periphery of a disc mounted to rotate on the leaf and provided with an operating means, these two rollers being able to cooperate, selectively as a function of the operation. of the disc, with one or the other of two respective ramps for spacing or bringing the leaf closer together mounted on the door frame.

Avantageusement, le disque comporte des moyens de retour automatique à une position neutre. Cela est particulièrement utile, si la porte doit être fermée ou ouverte par des utilisateurs venant des deux côtés. Advantageously, the disc comprises means for automatic return to a neutral position. This is particularly useful if the door is to be closed or opened by users from both sides.

Avantageusement, les galets sont écartés angulairement d'environ 1200. Advantageously, the rollers are spaced angularly by about 1200.

Avantageusement, le disque est monté rotatif sur le battant sans axe mobile traversant, ce qui est particulièrement appréciable pour les portes des cages de Faraday. Advantageously, the disc is rotatably mounted on the leaf without a movable traversing axis, which is particularly appreciable for the doors of the Faraday cages.

Avantageusement, il est prévu deux systèmes d'assistance respectivement d'un côté et de l'autre côté du battant. Advantageously, two assistance systems are provided respectively on one side and on the other side of the leaf.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante de l'invention. Il sera fait référence aux dessins annexé sur lesquels la figure 1 est une vue perspective en éclaté d'un premier mode de réalisation conforme à l'invention. Other characteristics and advantages of the invention will emerge from the following description of the invention. Reference will be made to the accompanying drawings in which Figure 1 is an exploded perspective view of a first embodiment according to the invention.

la figure 2 est une vue en coupe horizontale du dispositif de la figure 1. FIG. 2 is a view in horizontal section of the device of FIG. 1.

la figure 3 est une vue perspective arrière du dispositif de la figure 1. FIG. 3 is a rear perspective view of the device of FIG. 1.

la figure 4 est une vue perspective d'une variante du dispositif. Figure 4 is a perspective view of a variant of the device.

On voit sur les figures le battant 1 de porte et une pièce 2 fixée au dormant. A l'avant du battant 1, une semelle-axe 3 circulaire est boulonnée grâce à des vis 4 et des écrous 5. On notera que les vis 4 traversent le battant 1 mais sont des éléments fixes et sans jeu, donc non préjudiciables à la réalisation d'une cage de Faraday. The figures show the door leaf 1 and a part 2 fixed to the frame. At the front of the leaf 1, a circular sole-axis 3 is bolted using screws 4 and nuts 5. It will be noted that the screws 4 pass through the leaf 1 but are fixed elements and without play, therefore not detrimental to the creation of a Faraday cage.

La semelle 3 comporte une couronne intérieure 6 en saillie, dans l'épaisseur de laquelle est formée une rainure circulaire frontale 7. Cette rainure 7 loge deux ressorts à boudin 8 et 9 dont une extrémité est bloquée par une butée 10,11. Entre les ressorts 8,9 est introduite une goupille 12 liée au disque 13 (vissée dans le couvercle 14). The sole 3 has an inner crown 6 projecting, in the thickness of which is formed a front circular groove 7. This groove 7 houses two coil springs 8 and 9, one end of which is blocked by a stop 10,11. Between the springs 8, 9 is introduced a pin 12 linked to the disc 13 (screwed into the cover 14).

Le disque 13 comporte une couronne mobile 15 portant d'une part les galets radiaux 16 et 17 écartés de 1200, et d'autre part, à 1200 encore, le levier de manoeuvre 18. La couronne 15 tourne sur la couronne 6 de la semelle grâce à un roulement à billes intermédiaire 19 bloqué par un circlips 20 et protégé par le couvercle 14 vissé par des vis 21 sur la couronne 15. The disc 13 comprises a movable crown 15 carrying on the one hand the radial rollers 16 and 17 spaced by 1200, and on the other hand, at 1200 again, the operating lever 18. The crown 15 rotates on the crown 6 of the sole by means of an intermediate ball bearing 19 blocked by a circlip 20 and protected by the cover 14 screwed by screws 21 on the crown 15.

Une bille 22, appuyée en permanence par un ressort 23 taré par une vis 24 du couvercle 14 peut s'encastrer partiellement dans un évidement 25 de la semelle 3 de manière à former un point dur marquant la position neutre du disque de manoeuvre. A ball 22, permanently supported by a spring 23 calibrated by a screw 24 of the cover 14 can be partially embedded in a recess 25 in the sole 3 so as to form a hard point marking the neutral position of the operating disc.

La pièce 2 porte une cale en acier cambré à double pente 30 formant deux rampes 31 et 32 respectivement d'écartement et de rapprochement du battant 1 d'avec le dormant. The part 2 carries a wedge in cambered steel with a double slope 30 forming two ramps 31 and 32 respectively for spacing and bringing the leaf 1 closer to the frame.

Le fonctionnement du dispositif est le suivant. The operation of the device is as follows.

En position neutre, le levier de manoeuvre 18 est, tel que représenté sur les figures, à l'horizontale. Dans cette position, les galets 16 et 17 sont respectivement en dessous et au dessus du niveau de la pièce 30 et ne coopèrent pas avec celle-ci. In the neutral position, the operating lever 18 is, as shown in the figures, horizontal. In this position, the rollers 16 and 17 are respectively below and above the level of the part 30 and do not cooperate with the latter.

En supposant la porte fermée (telle que représentée), l'ouverture se fait en manoeuvrant la poignée 18 vers le bas : le galet 16 vient alors attaquer la rampe 32 d'éloignement, ce qui oblige la porte à s'entrouvrir. En lachant la poignée, le disque de manoeuvre revient à se position neutre grâce au ressort de rappel 9 et à la goupille 12. Assuming the door closed (as shown), the opening is done by maneuvering the handle 18 downwards: the roller 16 then comes to attack the ramp 32 of distance, which forces the door to open. By loosening the handle, the operating disc returns to its neutral position thanks to the return spring 9 and the pin 12.

La manoeuvre inverse permet la fermeture complète de la porte. On commence par pousser le battant contre le dormant, puis, en manoeuvrant le levier 18 vers le haut, le galet 17 vient attaquer la rampe de rapprochement 31, ce qui contraint la porte à se fermer complètement. Après avoir lâché le levier 18, celui-ci revient à la position neutre grâce au ressort de rappel 8 et à la goupille 12. The reverse operation allows the complete closing of the door. We start by pushing the leaf against the frame, then, by operating the lever 18 upwards, the roller 17 comes to attack the approach ramp 31, which forces the door to close completely. After releasing the lever 18, it returns to the neutral position thanks to the return spring 8 and the pin 12.

Il est avantageux de pourvoir le battant 1 d'un second système 40 sensiblement identique au premier, si l'aide à la fermeture et à l'ouverture est nécessaire des deux côtés. L'intérêt du mode de réalisation des figures 1 à 3 est qu'il ne fait appel à aucun axe mobile traversant le battant, ce qui est indispensable pour obtenir une bonne cage de Faraday. Si l'application visée est d'un autre domaine (par exemple, une porte de chambre froide), et qu'un axe traversant ne soit pas gênant, on peut tout simplement prévoir un axe traversant 41 lié au disque 13 du premier système, et pourvu d'un second levier de manoeuvre 42.  It is advantageous to provide the leaf 1 with a second system 40 which is substantially identical to the first, if assistance in closing and opening is necessary on both sides. The advantage of the embodiment of Figures 1 to 3 is that it does not use any movable axis crossing the leaf, which is essential to obtain a good Faraday cage. If the intended application is from another field (for example, a cold room door), and a traversing axis is not annoying, one can simply provide a traversing axis 41 linked to the disc 13 of the first system, and provided with a second operating lever 42.
