Abstract
Description
La présente invention concerne un dispositif de détection du déplacement relatif d'un ouvrant et d'un dormant d'une porte ou fenêtre.The present invention relates to a device for detecting the relative movement of an opening and a frame of a door or window.
Il est connu d'utiliser un Interrupteur à Lame Souple (ILS), pour détecter l'ouverture et la fermeture d'une porte ou fenêtre comprenant une ouverture qui peut-être à la française ou coulissante par exemple.It is known to use a Flexible Blade Switch (ILS) to detect the opening and closing of a door or window comprising an opening which may be French or sliding, for example.
Un ILS est un détecteur de champs magnétique qui est habituellement relié à une alarme par un circuit électrique ou électronique. Lorsqu'un ILS est en vis-à-vis d'un aimant, l'ILS est dans un premier état et lorsqu'il n'est plus en vis-à-vis de cet aimant, l'ILS est dans un second état. Ainsi, en plaçant un aimant permanent et un ILS sur l'ouvrant et le dormant d'une porte ou fenêtre, il est possible de détecter l'ouverture ou la fermeture d'une porte ou fenêtre selon l'état de l'ILS.An ILS is a magnetic field detector that is usually connected to an alarm by an electrical or electronic circuit. When an ILS is vis-à-vis a magnet, the ILS is in a first state and when it is no longer vis-à-vis this magnet, the ILS is in a second state . Thus, by placing a permanent magnet and an ILS on the opening and the frame of a door or window, it is possible to detect the opening or closing of a door or window according to the state of the ILS.
La demande de brevet français
Sur l'ouvrant est monté un bloc dit de commande qui comprend une pluralité de logements prévus pour accueillir chacun un aimant permanent. Seuls dans certains de ces logements sont placés des aimants permanents.On the opening is mounted a so-called control block which comprises a plurality of housings each for receiving a permanent magnet. Only in some of these dwellings are permanent magnets placed.
Sur le dormant est monté un bloc dit détecteur qui comprend une pluralité d'ILS.On the frame is mounted a so-called detector block which comprises a plurality of ILS.
La particularité de ce brevet vient du fait d'appareiller le bloc de commande et le bloc récepteur pour sécuriser le dispositif de détection contre une éventuelle tentative d'effraction. En effet, selon les logements du bloc de commande dans lesquels sont placés des aimants, des ILS du bloc récepteur sont positionnés en vis-à-vis. Cette combinaison est visuellement cachée à la vue et la multiplicité de combinaisons possibles, du fait de la pluralité de logements des blocs et du nombre variable d'ILS utilisés, évite qu'un éventuel fraudeur connaisse la combinaison utilisée pour sécuriser le dispositif de détection d'ouverture/fermeture.The peculiarity of this patent comes from pairing the control block and the receiver block to secure the detection device against a possible attempted break-in. Indeed, according to the housing of the control block in which magnets are placed, ILS of the receiver block are positioned vis-à-vis. This combination is visually hidden from view and the multiplicity of possible combinations, because of the plurality of housings of the blocks and the variable number of ILS used, avoids that a possible fraudster know the combination used to secure the detection device. 'open close.
Le bloc récepteur est relié à une centrale d'alarme via un étage détecteur équilibré réglé autour d'une valeur de résistance. Toute augmentation ou diminution de cette valeur révèle alors soit une ouverture de la fenêtre, soit une tentative de fraude ou de destruction du détecteur.The receiver unit is connected to an alarm center via a balanced detector stage set around a resistance value. Any increase or decrease in this value then reveals either an opening of the window or an attempt at fraud or destruction of the detector.
La demande de brevet français
Sur l'ouvrant est monté un aimant de commande.On the opening is mounted a control magnet.
Sur le dormant est monté un boîtier comprenant une plaquette qui porte un circuit imprimé constitué de conducteurs qui établissent, entre deux bornes, un circuit passant par deux ILS. L'un de ces ILS est sous l'effet de l'aimant de commande tandis qu'un autre aimant, monté dans le boîtier, est sous l'effet d'un aimant de garde pour former un interrupteur de garde.On the frame is mounted a housing comprising a plate which carries a printed circuit consisting of conductors which establish, between two terminals, a circuit passing through two ILS. One of these ILS is under the effect of the control magnet while another magnet, mounted in the housing, is under the effect of a guard magnet to form a guard switch.
Lorsqu'un fraudeur tente d'enlever la plaquette du boîtier, l'ILS de l'interrupteur de garde n'est plus sous l'effet de l'aimant de garde et une alarme peut être déclenchée. Par ailleurs, si un aimant frauduleux est inséré entre le boîtier et l'aimant de commande, l'ILS jusque là sous l'effet de cet aimant de commande, n'est plus sous l'effet de cet aimant. Une alarme peut alors être déclenchée.When a fraudster tries to remove the plate from the case, the ILS of the guard switch is no longer under the effect of the guard magnet and an alarm can be triggered. Moreover, if a fraudulent magnet is inserted between the housing and the control magnet, the ILS until then under the effect of this control magnet, is no longer under the effect of this magnet. An alarm can then be triggered.
Ainsi, lorsque la fenêtre est fermée, le champ magnétique de l'aimant de commande n'a d'effet que sur l'un des deux ILS.Thus, when the window is closed, the magnetic field of the control magnet only has an effect on one of the two ILSs.
Ces deux demandes de brevets proposent des solutions pour sécuriser un dispositif de détection du déplacement relatif d'un ouvrant et d'un dormant qui permet de considérer la fenêtre/porte comme étant ouverture dès qu'elle est entrebâillée.These two patent applications provide solutions for securing a device for detecting the relative movement of an opening and a frame which makes it possible to consider the window / door as being open as soon as it is ajar.
Le problème résolu par la présente invention est de déterminer un dispositif de détection qui permette de considérer, au contraire, qu'une porte ou fenêtre est fermée alors qu'elle est en réalité entrebâillée.The problem solved by the present invention is to determine a detection device that allows to consider, on the contrary, that a door or window is closed when it is actually ajar.
A cet effet, la présente invention concerne un dispositif de détection du déplacement relatif d'un ouvrant et d'un dormant d'une porte ou fenêtre caractérisé en ce qu'il comporte un aimant permanent monté à proximité de la face intérieure du dormant, et un détecteur monté sur l'ouvrant et formé de deux interrupteurs à lame positionnés sur l'ouvrant le plus loin possible l'un de l'autre.To this end, the present invention relates to a device for detecting the relative movement of an opening and a frame of a door or window characterized in that it comprises a permanent magnet mounted near the inner face of the frame, and a detector mounted on the opening and formed of two blade switches positioned on the opening as far as possible from one another.
Lorsque la fenêtre/porte est fermée, le champ magnétique de l'aimant permanent a un effet sur chaque ILS du détecteur qui sont alors dans un premier état : la fenêtre/porte est alors considérée comme étant fermée.When the window / door is closed, the magnetic field of the permanent magnet has an effect on each ILS of the detector which are then in a first state: the window / door is then considered closed.
Lorsque la fenêtre pivote autour d'un axe vertical (ouverture dite à la française) ou horizontal (soufflet, oscillo), les ILS s'éloignent de l'aimant.When the window rotates around a vertical axis (French-style opening) or horizontal (bellows, oscillo), the ILS move away from the magnet.
Lorsque la fenêtre est suffisamment ouverte (entrebâillée), le champ magnétique de l'aimant n'a d'effet que sur un seul des deux ILS du détecteur: soit celui situé à proximité de la face intérieure de l'ouvrant lorsque la fenêtre/porte pivote autour d'un axe vertical, soit celui situé à proximité de la face extérieure de l'ouvrant lorsque la fenêtre/porte pivote autour d'un axe horizontal. La fenêtre/porte est toujours considérée comme étant fermée alors qu'elle est en réalité entrebâillée.When the window is sufficiently open (ajar), the magnetic field of the magnet has effect on only one of the two ILS of the detector: the one located near the inner face of the opening when the window / door rotates about a vertical axis, that is, near the outer face of the opening when the window / door rotates around a horizontal axis. The window / door is still considered closed when it is actually ajar.
Lorsque la fenêtre/porte est encore plus ouverte, le champ magnétique n'a plus d'effet sur l'ILS qui était encore jusque là dans le premier état : la fenêtre est alors considérée comme étant ouverte.When the window / door is even more open, the magnetic field has no effect on the ILS which was still in the first state so far: the window is then considered to be open.
Ainsi, la présente invention permet à une fenêtre/porte d'être légèrement entrouverte (entrebâillée) sans pour autant qu'une alarme/signalisation soit déclenchée.Thus, the present invention allows a window / door to be slightly ajar (ajar) without an alarm / signaling is triggered.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels:The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the attached drawings, among which:
La Fig unique représente un mode de réalisation du dispositif selon l'invention lorsqu'il est mis en oeuvre sur une fenêtre oscillo-battante.The single FIG shows an embodiment of the device according to the invention when it is implemented on a tilt-and-turn window.
Sur la Fig. sont représentées des vues partielles d'une fenêtre oscillo-battante dans diverses positions d'ouverture.In FIG. Partial views of a tilt-and-turn window are shown in various open positions.
Le dispositif de détection du déplacement relatif d'un ouvrant et d'un dormant d'une porte ou fenêtre selon l'invention est ici décrit dans le cas d'une fenêtre oscillo-battante afin d'illustrer que ce dispositif permet de considérer qu'une fenêtre/porte est fermée lorsqu'elle est entrebâillée et ce que la fenêtre/porte ait pivoté autour d'un axe horizontal ou vertical. En particulier, le dispositif peut être utilisé pour contrôler l'ouverture/fermeture d'une porte ou d'une fenêtre qui peut être soit à ouverture à la française, soit à soufflet, soit oscillo-battante.The device for detecting the relative displacement of an opening and a frame of a door or window according to the invention is here described in the case of a tilt-and-turn window in order to illustrate that this device makes it possible to consider that a window / door is closed when it is ajar and the window / door has rotated about a horizontal or vertical axis. In particular, the device can be used to control the opening / closing of a door or window which can be either French-style, bellows or tilt-and-turn.
Sur la partie a) de la Fig., la fenêtre est représentée ouverte. On y voit l'ouvrant O et le dormant D. Un aimant permanent A est monté, ici vissé, sur le dormant et à proximité de la face intérieure du dormant D, c'est-à-dire la face qui est visible de l'intérieur de l'habitation. Un détecteur D est monté sur l'ouvrant O. Ce détecteur, de préférence de forme rectangulaire, est formé de deux interrupteurs à lame ILS distincts qui sont positionnés sur l'ouvrant O le plus loin possible l'un de l'autre, c'est-à-dire l'un à proximité de la face intérieure de l'ouvrant et l'autre à proximité de sa face extérieure.In part a) of Fig., The window is shown open. It shows the opening O and the frame D. A permanent magnet A is mounted, here screwed on the frame and near the inner face of the frame D, that is to say the face which is visible from the interior of the dwelling. A detector D is mounted on the opening O. This detector, preferably of rectangular shape, is formed of two distinct ILS blade switches which are positioned on the opening O as far as possible from each other, c that is to say one near the inner face of the opening and the other near its outer face.
Le détecteur D est relié à des moyens classiques d'alarme et/ou de signalisation qui sont activés selon l'état du détecteur qui indique si la fenêtre est ouverte ou fermée. Ces moyens sont prévus pour communiquer avec une centrale d'alarme et/ou de signalisation qui peut être de type radiofréquence ou filaire. Ces moyens sont également prévus pour qu'une alarme ou une signalisation particulière soit déclenchée lorsque les deux ILS du détecteur D ne sont plus sous l'effet de l'aimant permanent A.The detector D is connected to conventional means of alarm and / or signaling which are activated according to the state of the detector which indicates whether the window is open or closed. These means are intended to communicate with a central alarm and / or signaling which may be radiofrequency or wired type. These means are also provided so that an alarm or a particular signaling is triggered when the two ILS of the detector D are no longer under the effect of the permanent magnet A.
Ainsi, lorsque la fenêtre est fermée, le champ magnétique de l'aimant permanent A à un effet sur chaque ILS du détecteur D qui sont alors dans un premier état: la fenêtre est alors considérée comme étant fermée.Thus, when the window is closed, the magnetic field of the permanent magnet A has an effect on each ILS of the detector D which are then in a first state: the window is then considered to be closed.
Lorsque la fenêtre pivote autour d'un axe vertical (mode d'ouverture dit à la française), il se produit un moment où le champ magnétique de l'aimant permanent A n'a plus d'effet sur l'ILS situé à proximité de la face extérieure de l'ouvrant O. Cet ILS bascule alors dans un second état. Toutefois, cet aimant continue d'avoir un effet sur l'ILS situé à proximité de la face intérieure de l'ouvrant O. La fenêtre est alors entrebâillée mais les moyens d'alarme et/de signalisation considèrent que la fenêtre est toujours fermée étant donné que l'un des deux ILS est encore sous l'effet de l'aimant permanent A.When the window pivots around a vertical axis (French-style opening mode), a moment occurs when the magnetic field of the permanent magnet A has no effect on the nearby ILS. the outer face of the opening O. This ILS then switches to a second state. However, this magnet continues to have an effect on the ILS located near the inner face of the opening O. The window is then ajar but the alarm and / / signaling means consider that the window is still closed being given that one of the two ILS is still under the effect of the permanent magnet A.
Lorsque la fenêtre pivote encore autour de l'axe vertical, il se produit un moment où l'ILS du détecteur D, encore dans le premier état, n'est plus sous l'effet de l'aimant permanent A et bascule dans un second état. Les moyens d'alarme et/de signalisation considèrent alors que la fenêtre est ouverte.When the window is still pivoting about the vertical axis, a moment occurs when the ILS of the detector D, still in the first state, is no longer under the effect of the permanent magnet A and switches to a second one. state. The alarm and / / signaling means then consider that the window is open.
Les parties b) c) et d) de la Fig. représentent la fenêtre lorsqu'elle fonctionne en mode oscillo c'est-à-dire lorsqu'elle pivote autour d'un axe horizontal situé en partie basse de la fenêtre.Parts b) c) and d) of FIG. represent the window when it operates in oscillo mode that is to say when it pivots around a horizontal axis situated in the lower part of the window.
La partie b) représente la fenêtre lorsqu'elle est installée sur un mur M d'une habitation. La face intérieure FI de la fenêtre est celle qui donne sur l'intérieur de l'habitation et la face extérieure FE de la fenêtre est celle qui donne sur l'extérieur de l'habitation.Part b) represents the window when it is installed on a wall M of a dwelling. The inner face FI of the window is that which gives on the inside of the house and the outside face FE of the window is the one which gives on the outside of the house.
Lorsque la fenêtre pivote autour de l'axe horizontal, il se produit un moment où le champ magnétique de l'aimant permanent A n'a plus d'effet sur l'ILS situé à proximité de la face intérieure de l'ouvrant O. Cet ILS bascule alors dans un second état. Toutefois, cet aimant continue d'avoir un effet sur l'ILS situé à proximité de la face extérieure de l'ouvrant O. La fenêtre est alors entrebâillée mais les moyens d'alarme et/de signalisation considèrent que la fenêtre est toujours fermée étant donné que l'un des deux ILS est encore sous l'effet de l'aimant permanent A.When the window pivots around the horizontal axis, a moment occurs when the magnetic field of the permanent magnet A has no effect on the ILS located near the inner face of the opening O. This ILS then switches to a second state. However, this magnet continues to have an effect on the ILS located near the outer face of the opening O. The window is then ajar but the alarm and / / signaling means consider that the window is still closed being given that one of the two ILS is still under the effect of the permanent magnet A.
Lorsque la fenêtre pivote encore autour de l'axe horizontal, il se produit un moment où l'ILS du détecteur D, encore dans le premier état, n'est plus sous l'effet de l'aimant permanent A et bascule dans un second état. Les moyens d'alarme et/de signalisation considèrent alors que la fenêtre est ouverte.When the window is still pivoting around the horizontal axis, there is a moment when the ILS of the detector D, still in the first state, is no longer under the effect of the permanent magnet A and switches to a second state. The alarm and / / signaling means then consider that the window is open.
Ainsi, par le positionnement éloigné des deux ILS, le dispositif de détection, selon l'invention, permet à une fenêtre/porte d'être légèrement entrouverte (entrebâillée) sans pour autant qu'une alarme/signalisation particulière soit déclenchée.Thus, by the remote positioning of the two ILS, the detection device according to the invention allows a window / door to be slightly ajar (ajar) without a particular alarm / signaling is triggered.
