Description

La présente invention a trait à un dispositif de fermeture ou d'occultation pour une construction.The present invention relates to a closing or concealing device for a construction.

Cette invention a trait au domaine du bâtiment et, plus particulièrement, au domaine de la fabrication des installations conçues pour fermer une ouverture que comporte une construction ou conçues pour occulter une pièce d'une telle construction. En fait, cette invention trouvera une application particulièrement appropriée dans le cadre d'une porte de garage ou d'un volet roulant sans que la présente invention n'y soit aucunement limitée.This invention relates to the field of building and, more particularly, to the field of the manufacture of installations designed to close an opening in a construction or designed to conceal a room of such a construction. In fact, this invention will find a particularly suitable application in the context of a garage door or a roller shutter without the present invention being in any way limited thereto.

L'on connait, d'ores et déjà, des dispositifs de fermeture qui peuvent adopter la forme d'un tablier d'une porte de garage apte à refermer un tel garage. Un tel tablier comporte une pluralité de portions qui sont articulées deux à deux dont une portion finale. Ces portions sont constituées, chacune, par une section, notamment adoptant la forme d'un panneau, en sorte de définir un tablier de porte de garage sectionnelle. Ce tablier peut être complété par des moyens d'entraînement motorisés qui comportent, d'une part, un moteur usuellement fixé au plafond du garage ou sur une structure fixée au plafond et/ou sur les murs du garage et, d'autre part, un organe de transmission, en prise avec le tablier et avec le moteur, et configuré pour exercer une traction sur ce tablier en vue de le replier ainsi que pour exercer une répulsion sur ce tablier en vue de le déployer. Un tel moteur et un tel organe de transmission représentent un encombrement conséquent dont on ne dispose pas toujours pour leur implantation dans un garage. A contrario, lorsque le tablier est éloigné du plafond du garage, il est nécessaire de recourir à une structure additionnelle, qui est rendue solidaire de ce plafond et/ou des murs du garage, et de laquelle ledit moteur est rendu solidaire. Outre le fait que cette structure constitue un élément additionnel, l'implantation d'une telle structure nécessite un allongement de la durée d'implantation de la porte de garage ce qui accroît notablement le coût de cette dernière.Closing devices are already known which can take the form of an apron of a garage door capable of closing such a garage. Such an apron comprises a plurality of portions which are articulated in pairs, including a final portion. These portions are each constituted by a section, in particular adopting the shape of a panel, so as to define a sectional garage door apron. This apron can be supplemented by motorized drive means which comprise, on the one hand, a motor usually fixed to the ceiling of the garage or to a structure fixed to the ceiling and / or to the walls of the garage and, on the other hand, a transmission member, engaged with the apron and with the engine, and configured to exert traction on this apron with a view to folding it up as well as to exert repulsion on this apron with a view to deploying it. Such a motor and such a transmission member represent a substantial bulk which is not always available for their installation in a garage. Conversely, when the apron is away from the garage ceiling, it is necessary to resort to an additional structure, which is made integral with this ceiling and / or the walls of the garage, and with which said motor is made integral. Besides the fact that this structure constitutes an additional element, the installation of such a structure requires an extension of the installation time of the garage door, which significantly increases the cost of the latter.

L'on connaît, encore, des dispositifs de fermeture qui peuvent adopter la forme d'un tablier de volet roulant, qui complète une porte, une fenêtre, une porte-fenêtre ou analogue, et qui permet d'occulter l'intérieur d'une pièce ou au moins en partie d'assombrir l'intérieur d'une telle pièce. Un tel tablier comporte, là encore, une pluralité de portions qui sont articulées deux à deux dont une portion finale. Ces portions de tablier sont constituées, chacune, par une lame de tablier. Ce tablier peut être complété, d'une part, par un tube d'enroulement sur lequel s'enroulent et à partir duquel se déroulent les lames du tablier et, d'autre part, par des moyens d'entraînement motorisés de ce tube d'enroulement, ces moyens d'entraînement pouvant, avantageusement, être implantés à l'intérieur du tube d'enroulement. En position repliée du tablier, les lames de ce tablier sont enroulées sur le tube d'enroulement et l'ensemble, constitué par ce tube d'enroulement et ces lames, vient se loger à l'intérieur d'un caisson de volet roulant. Ce caisson de volet roulant doit, par conséquent, être dimensionné pour pouvoir recevoir un tel ensemble de sorte que ce caisson présente, souvent, des dimensions importantes. Ces dimensions importantes font que ce caisson dépasse, soit par rapport au mur intérieur, soit par rapport à la façade, ce qui nuit à l'esthétique de la construction.Closing devices are also known which can take the form of a roller shutter apron, which completes a door, a window, a French window or the like, and which makes it possible to conceal the interior of the shutter. a room or at least partially to darken the interior of such a room. Such an apron comprises, here again, a plurality of portions which are articulated in pairs, including a final portion. These apron portions are each constituted by an apron strip. This apron can be completed, on the one hand, by a winding tube on which wind and from which the slats of the apron unwind and, on the other hand, by motorized drive means of this tube. 'winding, these drive means being able, advantageously, to be implanted inside the winding tube. In the folded position of the apron, the slats of this apron are wound on the winding tube and the assembly, consisting of this winding tube and these slats, is housed inside a roller shutter box. This roller shutter box must therefore be dimensioned to be able to receive such an assembly so that this box often has large dimensions. These large dimensions cause this box to protrude, either with respect to the interior wall or with respect to the facade, which is detrimental to the aesthetics of the construction.

La demande internationale de brevet WO 88/06671 divulgue un dispositif de fermeture ou d'occultation selon le préambule de la revendication 1.The international patent application WO 88/06671 discloses a closing or concealment device according to the preamble of claim 1.

La présente invention se veut de remédier aux inconvénients des dispositifs de fermeture et/ou d'occultation de l'état de la technique.The present invention is intended to remedy the drawbacks of the closure and / or concealment devices of the state of the art.

Un autre but de la présente invention est de proposer un dispositif de fermeture ou d'occultation particulièrement compact.Another object of the present invention is to provide a particularly compact closing or concealment device.

Encore un autre but de l'invention est de proposer un dispositif de fermeture ou d'occultation, qui puisse détecter un obstacle lors de son déplacement, et qui puisse interrompre ce déplacement lors qu'un obstacle est détecté.Yet another object of the invention is to provide a closing or concealment device, which can detect an obstacle during its movement, and which can interrupt this movement when an obstacle is detected.

A cet effet, l'invention concerne un dispositif de fermeture ou d'occultation pour une construction. Ce dispositif comporte, d'une part, des moyens d'entraînement motorisés pour entraîner ce dispositif en déplacement entre une position d'ouverture et une position de fermeture ou d'occultation et, d'autre part, une pluralité de portions, qui sont articulées deux à deux, dont une portion finale, qui est destinée à venir se positionner au moins à proximité d'un seuil d'une ouverture d'une construction équipée avec un tel dispositif, et qui comporte au moins une cavité qui comporte, intérieurement, au moins une partie des moyens d'entraînement motorisés. Ce dispositif est caractérisé par le fait qu'il comporte:

  • et des moyens de commande pour commander l'arrêt de l'entraînement du dispositif par les moyens d'entraînement motorisés, ceci en cas de détection d'un tel obstacle par le système de détection.
To this end, the invention relates to a closing or concealing device for a building. This device comprises, on the one hand, motorized drive means for drive this device in movement between an open position and a closed or hidden position and, on the other hand, a plurality of portions, which are articulated in pairs, including a final portion, which is intended to come together position at least near a threshold of an opening of a construction equipped with such a device, and which comprises at least one cavity which comprises, internally, at least part of the motorized drive means. This device is characterized by the fact that it comprises:
  • detection system for detecting an obstacle in the path of this device, this detection system comprising, on the one hand, a locking means which is movable between an inactive locking position and an active locking position, on the other hand, at least one complementary locking means which is configured to cooperate with the motorized drive means as well as with the locking means, this in the active locking position of this locking means and, on the other hand, a means of actuation which is configured to actuate the movement of the blocking means from the inactive blocking position to the active blocking position, in the event of contact of such an actuating means with an obstacle;
  • and control means for controlling the stopping of the drive of the device by the motorized drive means, in the event of such an obstacle being detected by the detection system.

De manière additionnelle, la cavité de la portion finale comporte, également et intérieurement, au moins une partie de ce système de détection.Additionally, the cavity of the final portion includes, also and internally, at least part of this detection system.

Une autre caractéristique concerne le fait que le dispositif de fermeture ou d'occultation est constitué par un tablier de porte de garage sectionnelle qui comporte une pluralité de sections, qui sont articulées deux à deux, et qui constituent, chacune, une des portions du dispositif.Another characteristic relates to the fact that the closing or concealing device consists of a sectional garage door apron which comprises a plurality of sections, which are articulated in pairs, and which each constitute one of the portions of the device. .

De manière alternative, le dispositif de fermeture ou d'occultation est constitué par un tablier de volet roulant qui comporte une pluralité de lames, qui sont articulées deux à deux, et qui constituent, chacune, une des portions du dispositif. Ce dispositif comporte des moyens d'articulation qui sont configurés pour permettre un empilement d'au moins une partie des portions (c'est à dire des lames) de ce dispositif, plus particulièrement à l'intérieur d'un caisson de volet roulant.Alternatively, the closing or concealment device consists of a roller shutter apron which comprises a plurality of blades, which are articulated in pairs. two, and which each constitute one of the portions of the device. This device comprises articulation means which are configured to allow stacking of at least part of the portions (ie of the slats) of this device, more particularly inside a roller shutter box.

L'invention concerne, également, une installation de fermeture ou d'occultation pour une construction, cette installation comporte un dispositif de fermeture ou d'occultation qui présente les caractéristiques décrites ci-dessus.The invention also relates to a closing or concealing installation for a building, this installation comprising a closing or concealing device which has the characteristics described above.

Ainsi, l'invention concerne un dispositif de fermeture ou d'occultation qui comporte une portion (section ou lame) finale qui comporte une cavité comportant, intérieurement, au moins une partie des moyens d'entraînement motorisés de ce dispositif.Thus, the invention relates to a closing or concealing device which comprises a final portion (section or blade) which comprises a cavity comprising, internally, at least part of the motorized drive means of this device.

Dans cette invention, au moins une partie des moyens d'entraînement motorisés est implantée à l'intérieur de la portion finale.In this invention, at least part of the motorized drive means is located inside the final portion.

Ceci permet, avantageusement et dans le cas d'un volet roulant, de recourir à un tablier, qui comporte des portions (lames) qui peuvent être empilées à l'intérieur d'un caisson, et qui ne nécessitent plus de tube d'enroulement (notamment incorporant un moteur d'entraînement de ce tube d'enroulement). Le tablier replié présente un encombrement substantiellement réduit par rapport aux tabliers de l'état de la technique ce qui permet de réduire notablement la taille du caisson et ainsi d'améliorer l'esthétique de la construction.This allows, advantageously and in the case of a rolling shutter, to use an apron, which comprises portions (blades) which can be stacked inside a box, and which no longer require a winding tube. (in particular incorporating a motor for driving this winding tube). The folded apron has a substantially reduced size compared to the aprons of the state of the art, which makes it possible to significantly reduce the size of the box and thus to improve the aesthetics of the construction.

Ceci permet, également, avantageusement, et dans le cas d'une porte de garage de s'affranchir d'un ensemble (moteur et moyens de transmission) encombrant, de la fixation d'un tel moteur au plafond, ou de recourir à une structure additionnelle pour le montage d'un tel ensemble.This also allows, advantageously, and in the case of a garage door to dispense with a cumbersome assembly (motor and transmission means), the fixing of such a motor to the ceiling, or to have recourse to a additional structure for mounting such an assembly.

Finalement, le dispositif de fermeture ou d'occultation comporte un système de détection pour détecter un obstacle sur la trajectoire de ce dispositif ainsi que des moyens de commande de l'arrêt de l'entraînement de ce dispositif en cas de détection d'un tel obstacle. Ceci permet, avantageusement, d'interrompre le déploiement du tablier si un obstacle (par exemple un enfant ou un objet quelconque) se trouve sur la trajectoire de ce tablier.Finally, the closing or concealment device comprises a detection system for detecting an obstacle in the path of this device as well as means for controlling the stopping of the drive of this device in the event of detection of such an obstacle. This advantageously makes it possible to interrupt the deployment of the apron if an obstacle (for example a child or any object) is in the path of this apron.

Le système de détection est en grande partie logé à l'intérieur de la cavité de la portion finale ce qui permet un gain de place substantiel. De plus, ce système de détection comporte des éléments (moyens de blocage, moyens de blocage complémentaires, moyens d'actionnement) de dimensions réduites et de conception simple ce qui permet, avantageusement, de conférer une fiabilité accrue au dispositif de fermeture ou d'occultation selon l'invention.The detection system is for the most part housed inside the cavity of the final portion, which saves substantial space. In addition, this detection system comprises elements (blocking means, complementary blocking means, actuating means) of reduced dimensions and of simple design which advantageously makes it possible to confer increased reliability on the closing device or occultation according to the invention.

La présente invention concerne le domaine du bâtiment et, plus particulièrement, le domaine de la fabrication des installations conçues, soit pour fermer une ouverture que comporte une construction, soit pour occulter l'intérieur d'une pièce que comporte une telle construction ou au moins en partie d'assombrir l'intérieur d'une telle pièce.The present invention relates to the field of building and, more particularly, to the field of the manufacture of installations designed either to close an opening that a construction has, or to conceal the interior of a room that such a construction comprises or at least. partly to darken the interior of such a room.

Une telle installation 1 peut, alors, être une installation de fermeture constituée par une porte de garage de type basculante ou séquentielle. Cette installation 1 comporte un dispositif de fermeture 2, qui est constitué par un tablier de porte de garage, et qui referme une ouverture que comporte la construction. Ce tablier (dispositif de fermeture 2) d'une porte de garage séquentielle comporte une pluralité de portions (3; 3') articulées deux à deux par l'intermédiaire de moyens d'articulation 31. Chacune de ces portions (3 ; 3') est, alors usuellement, dénommée section. Ce tablier comporte, en particulier, une portion finale 3 (usuellement dénommée section finale) destinée à venir se positionner à proximité d'un seuil de l'ouverture de la construction (voire en butée contre ce seuil), ceci en position de fermeture de ce dispositif de fermeture.Such an installation 1 can then be a closing installation consisting of a garage door of the tilting or sequential type. This installation 1 comprises a closing device 2, which consists of a garage door apron, and which closes an opening that the construction includes. This apron (closing device 2) of a sequential garage door comprises a plurality of portions (3; 3 ') articulated in pairs by means of articulation means 31. Each of these portions (3; 3') ) is then usually called section. This apron comprises, in particular, a final portion 3 (usually referred to as the final section) intended to be positioned near a threshold of the opening of the construction (or even in abutment against this threshold), this in the closed position of the building. this closing device.

De manière alternative, une telle installation 1 peut, encore, être une installation d'occultation constituée par un volet roulant qui complète une porte, une fenêtre ou analogue laquelle referme une ouverture que comporte la construction. Une telle installation 1 comporte, alors, un dispositif d'occultation 2, qui est constitué par un tablier de volet roulant, et qui occulte ou assombrit l'intérieur d'une pièce de cette construction. Ce tablier (dispositif d'occultation 2) de volet roulant comporte une pluralité de portions (3 ; 3') articulées deux à deux par l'intermédiaire de moyens d'articulation 30. Chacune de ces portions (3 ; 3') est, alors, constituée par une lame de tablier de volet roulant. Ce tablier comporte, en particulier, une portion finale 3 (constituée par une lame finale) destinée à venir se positionner à proximité d'un seuil de l'ouverture de la construction (voire en butée contre ce seuil), ceci en position de fermeture de ce dispositif d'occultation 2.Alternatively, such an installation 1 can, again, be a concealment installation consisting of a roller shutter which completes a door, a window or the like which closes an opening that the construction includes.

This shutter (concealment device 2) of the rolling shutter comprises a plurality of portions (3; 3 ') articulated in pairs by means of articulation means 30. Each of these portions (3; 3') is, then, constituted by a roller shutter apron blade. This apron comprises, in particular, a final portion 3 (constituted by a final slat) intended to be positioned near a threshold of the opening of the construction (or even in abutment against this threshold), this in the closed position. of this concealment device 2.

Ainsi, une telle installation 1 de fermeture, respectivement d'occultation, comporte, alors, un dispositif 2 de fermeture, respectivement d'occultation.Thus, such an installation 1 for closing, respectively for concealing, then comprises a device 2 for closing, respectively for concealing.

Un tel dispositif de fermeture ou d'occultation 2 est mobile entre une position d'ouverture et une position de fermeture (notamment pour un tablier de porte de garage) ou d'occultation (notamment pour un tablier de volet roulant), ceci selon une course déterminée.Such a closing or concealing device 2 is movable between an open position and a closed position (in particular for a garage door apron) or of concealment (in particular for a roller shutter apron), this according to a determined race.

Ainsi, lors de la fermeture du dispositif de fermeture ou d'occultation 2 de cette installation 1, ce dispositif 2 se déplace en sorte que sa portion finale 3 se dirige en direction du seuil de l'ouverture de la construction équipée d'une telle installation 1.Thus, when the closing or concealment device 2 of this installation 1 is closed, this device 2 moves so that its final portion 3 points in the direction of the threshold of the opening of the construction equipped with such a installation 1.

Sous l'effet du déplacement de ce dispositif de fermeture ou d'occultation 2 et lorsque ce dispositif 2 (plus particulièrement la portion finale 3 de ce dispositif 2) entre en contact avec un obstacle, le moyen d'actionnement 52 (que comporte le système de détection 5 de ce dispositif 2) entre en contact avec cet obstacle et commande le déplacement du moyen de blocage 50 (que comporte ce système de détection 5) qui passe d'une position inactive de blocage à une position active de blocage dans laquelle ce moyen de blocage 50 coopère avec ledit au moins un moyen de blocage complémentaire 51 (que comporte ce système de détection 5) pour en assurer le blocage.Under the effect of the movement of this closing or concealing device 2 and when this device 2 (more particularly the final portion 3 of this device 2) between in contact with an obstacle, the actuating means 52 (which the detection system 5 of this device 2 comprises) comes into contact with this obstacle and controls the movement of the locking means 50 (which this detection system 5 comprises) which passes from an inactive blocking position to an active blocking position in which this blocking means 50 cooperates with said at least one complementary blocking means 51 (which this detection system 5 comprises) to ensure its blocking.

Le blocage dudit moyen de blocage complémentaire 51 provoque le blocage en rotation de l'élément 7 ce qui entraîne le blocage en rotation de l'arbre de transmission 41 que comportent les moyens d'entraînement motorisés 4 et, donc, le blocage du moteur 40 (plus particulièrement du rotor de ce moteur 40) de ces moyens d'entraînement motorisés 4. Ce blocage se traduit par une variation du régime et/ou du couple de ces moyens d'entraînement motorisé 4, plus particulièrement une variation du régime et/ou du couple du moteur 40 de ces moyens d'entraînement motorisé 4.The locking of said complementary locking means 51 causes the locking in rotation of the element 7 which causes the locking in rotation of the transmission shaft 41 that comprises the motorized drive means 4 and, therefore, the locking of the motor 40 (more particularly the rotor of this motor 40) of these motorized drive means 4. This blocking results in a variation of the speed and / or of the torque of these motorized drive means 4, more particularly a variation of the speed and / or the torque of the motor 40 of these motorized drive means 4.

La détection (par le moyen d'analyse que comporte le système de détection 5) de cette variation de régime et/ou du couple du moteur 40 permet de commander une coupure de l'alimentation de ce moteur 40 en énergie électrique et, par conséquent, un arrêt de l'entraînement du dispositif 2 par les moyens d'entraînement motorisés 4, et, donc, un arrêt du déplacement de ce dispositif de fermeture ou d'occultation 2.The detection (by the analysis means that comprises the detection system 5) of this variation of speed and / or of the torque of the motor 40 makes it possible to order a cut-off of the supply of this motor 40 with electrical energy and, consequently , a stopping of the drive of the device 2 by the motorized drive means 4, and, therefore, a stopping of the movement of this closing or concealment device 2.
