Abstract

The system controls several windows (6), which are hinged at the bottom. The thin wires or rods (2,3) controlling each individual window are fastened at their ends to fittings (19,18) on the upper part (21) of the window frame. They pass through fittings (4) on the top of the fixed frame (7), and pass through tubular guides (5) which may be curved and lead to a lever or wheel for pulling on the rods or wires to open or close the window.

Description

La présente invention est relative à un dispositif de commande à distanceThe present invention relates to a remote control device

de l'ouverture d'un élément mobile tel que notamment un ferme- imposte, qui permet l'ouverture et la fermeture d'un ouvrant ou tout élément mobile similaire appartenant à une fenêtre, une trappe, un exutoire à fumée,  the opening of a mobile element such as in particular a fanlight closer, which allows the opening and closing of an opening or any similar mobile element belonging to a window, a hatch, a smoke outlet,

un châssis ouvrant, ou au sein d'un cadre.  an opening frame, or within a frame.

On connait à l'heure actuelle des systèmes de commande à distance d'ouverture et de fermeture d'éléments mobiles  At the present time, remote control systems for opening and closing mobile elements are known.

qui comportent généralement, dans un boîtier, un moto-  which generally include, in a housing, a moto-

réducteur réalisé à l'aide d'un train d'engrenages, ou d'un couple, roue et vis sans fin, connecté à un tambour sur lequel est enroulé le câble relié à la partie mobile à actionner. Les normes en matière de sécurité et de lutte contre l'incendie imposent des temps d'ouverture très brefs, sous une charge donnée, la libération de la charge devant être effectuée par une action franche sur un organe de commande  reducer produced using a gear train, or a torque, wheel and worm, connected to a drum on which is wound the cable connected to the mobile part to be actuated. The standards in terms of security and fire fighting impose very short opening times, under a given load, the release of the load to be carried out by a frank action on a control member.

aisément accessible par un utilisateur non spécialiste.  easily accessible by a non-specialist user.

Les systèmes connus comprennent également un dispositif de commande, protégé éventuellement par une vitre ou un capot, à briser ou à ôter, chargé de libérer le tambour de la chaîne cinématique du moto-réducteur, étant entendu que les mécanismes incorporés dans le boîtier possèdent une irréversibilité dans l'un de leurs sens de rotation. Or, la libération du système de commande nécessite, quelquefois du fait de l'utilisateur, un laps de temps pour briser ou Èter, respectivement la vitre ou le capot, ce qui induit un léger temps mort dans le mouvement d'ouverture ou de fermeture de l'élément mobile. Par ailleurs, les solutions technologiques classiques mises en oeuvre dans les dispositifs connus, prévoient généralement la séparation par basculement ou par écartement de l'un des organes constituant le train d'engrenages. Ces solutions nécessitent l'emploi d'un boitier d'encombrement important afin de créer un espace suffisant pour le désaccouplement de l'un des pignons, cette opération constituant d'ailleurs un inconvénient lors du réarmement, car il n'est pas facile de réengager l'un des engrenages dans la chaîne  Known systems also include a control device, possibly protected by a window or a cover, to be broken or removed, responsible for releasing the drum from the kinematic chain of the gear motor, it being understood that the mechanisms incorporated in the housing have a irreversibility in one of their directions of rotation. However, the release of the control system requires, sometimes because of the user, a period of time to break or remove, respectively the window or the cover, which induces a slight dead time in the opening or closing movement. of the movable element. Furthermore, the conventional technological solutions implemented in known devices generally provide for separation by tilting or by separation of one of the members constituting the gear train. These solutions require the use of a large space unit in order to create sufficient space for the uncoupling of one of the pinions, this operation also constituting a drawback during rearming, since it is not easy to re-engage one of the gears in the chain

On connaît par ailleurs d'autres dispositifs de commande à distance de l'ouverture d'un élément mobile tel que notamment un ferme-imposte, destinés à être manoeuvrés manuellement à l'aide d'une poignée coulissante ou d'un levier. Généralement, ces organes agissent par le biais d'un câble coulissant au travers d'un tube ou d'une gaine et qui est relié à son autre extrémité à un organe de verrouillage  Other devices are also known for remote control of the opening of a movable element such as in particular a fanlight closer, intended to be operated manually using a sliding handle or a lever. Generally, these members act by means of a cable sliding through a tube or a sheath and which is connected at its other end to a locking member.

communément appelé récepteur.commonly called a receiver.

Ce récepteur est toujours composé d'au moins deux éléments, une partie fixée sur la partie mobile constituant l'ouvrant, et une partie montée sur la partie fixe  This receiver is always composed of at least two elements, a part fixed on the mobile part constituting the opening, and a part mounted on the fixed part.

constituant le dormant.constituting the frame.

Ainsi, lorsque l'on veut actionner à l'aide de ce type de dispositif de commande plusieurs ouvrants et donc agir à partir d'une seule manoeuvre sur plusieurs récepteurs, on utilise un dispositif de commande à deux sorties, une crémaillère ou une barre rigide ou encore un câble à spires  Thus, when one wishes to actuate using this type of control device several opening elements and therefore act from a single operation on several receivers, a control device with two outputs, a rack or a bar, is used rigid or a cable with turns

qui peut entraîner plusieurs éléments disposés en série.  which can cause several elements arranged in series.

Quel que soit le type de manoeuvre, manuelle ou à treuil, les dispositifs connus de l'art antérieur utilisent un unique câble pour agir sur plusieurs récepteurs, ce qui nécessite des dispositifs de renvoi qui peuvent provoquer en raison de leur cinématique des difficultés de fonctionnement des ouvrants ou des retards dans leur ouverture. La présente invention vise donc à pallier ces inconvénients en proposant un dispositif de commande, robuste et fiable, qui utilise au moins deux câbles de manière à agir avec une très grande rapidité d'action pour  Whatever the type of operation, manual or winch, the known devices of the prior art use a single cable to act on several receivers, which requires return devices which can cause, due to their kinematics, operating difficulties. opening or delays in their opening. The present invention therefore aims to overcome these drawbacks by proposing a control device, robust and reliable, which uses at least two cables so as to act with a very high speed of action to

une meilleure sécurité sur les ouvrants.  better security on the sashes.

A cet effet, le dispositif de commande à distance, objet de l'invention, comportant un organe de commande agissant sur au moins un organe de liaison permettant d'actionner au moins une partie mobile formant ouvrant solidaire d'un châssis formant dormant se caractérise en ce  To this end, the remote control device, object of the invention, comprising a control member acting on at least one connecting member making it possible to actuate at least one movable part forming an opening integral with a frame forming a frame is characterized in this

qu'il comporte au moins un récepteur fixé sur le châssis du dormant, ledit récepteur étant muni d'orifices permettant le passage d'au moins un organe de liaison en direction d'un second récepteur permettant ainsi le mouvement simultané des parties mobiles à partir de l'organe de commande. D'autres caractéristiques et avantages de la présente  that it comprises at least one receiver fixed to the frame of the frame, said receiver being provided with orifices allowing the passage of at least one connecting member in the direction of a second receiver thus allowing the simultaneous movement of the movable parts from of the control unit.
