Description

La présente invention concerne une porte rapide à rideau souple.The present invention relates to a fast door with flexible curtain.

Les portes à rideau souple, qu'elles soient à repliement ou enroulement vertical, ont comme particularité d'être manoeuvrées à des vitesses linéaires importantes. Une porte à rideau souple selon le préambule de la revendication 1 est connue du DE-U-29623251 . Ces vitesses d'ouvertures et fermetures importantes sont rendues possible par la faible inertie du rideau souple généralement réalisé en PVC ou en matériau souple similaire.The soft curtain doors, whether folding or vertical winding, have the particular feature of being operated at high linear speeds. A flexible curtain door according to the preamble of claim 1 is known from DE-U-29623251 . These speeds of openings and closures are made possible by the low inertia of the flexible curtain generally made of PVC or similar flexible material.

Il est donc essentiel de sécuriser le fonctionnement de ces portes et d'éviter, lors d'une collision accidentelle entre une personne ou un objet et le rideau, un écrasement ou une altération de la personne de l'objet ou du rideau.It is therefore essential to secure the operation of these doors and to avoid, during an accidental collision between a person or an object and the curtain, a crushing or an alteration of the person of the object or the curtain.

Il existe plusieurs systèmes assurant une certaine sécurisation du fonctionnement des portes rapides à écran souple par détection d'objets ou de personnes qui se trouvent accidentellement sous le rideau ou à proximité immédiate de celui-ci, lorsqu'il se referme.There are several systems providing some security for the operation of the flexible screen quick-opening doors by detecting objects or persons who accidentally are under the curtain or in the immediate vicinity of the curtain, when it closes.

Un premier système de détection prévoit d'équiper un périmètre autour de la porte de détecteurs de présence. Il faut généralement plusieurs détecteurs de présence pour sécuriser un périmètre suffisant pour détecter la présence d'une personne ou d'un objet lors d'une phase de fermeture de la porte, ce qui présente alors un risque de collision et d'écrasement ou d'altération du rideau. Ces systèmes sont toutefois coûteux et peuvent être sensibles à de fausses alertes.A first detection system plans to equip a perimeter around the door of presence detectors. It usually takes several presence detectors to secure a perimeter sufficient to detect the presence of a person or object during a closing phase of the door, which then presents a risk of collision and crushing or alteration of the curtain. These systems, however, are expensive and may be susceptible to false alarms.

Il existe également des systèmes de détection fonctionnant sur le principe de la détection d'un contact. La détection d'un contact lors de la phase de fermeture du rideau génère un signal, généralement électrique, qui entraîne un arrêt de la phase de fermeture du rideau.There are also detection systems operating on the principle of the detection of a contact. The detection of a contact during the closing phase of the curtain generates a signal, usually electrical, which causes a stop of the closing phase of the curtain.

Dans le cas de rideau équipé de barres de renfort notamment dans sa partie basse, un système de détection connu consiste à ajouter sous la barre de renfort rigide inférieure un moyen de détection. Ce moyen de détection qui, par exemple, peut être un boudin d'air, s'écrase contre la barre rigide lors d'une collision avec une personne ou un objet.In the case of curtain equipped with reinforcing bars in particular in its lower part, a known detection system consists in adding under the lower stiff reinforcement bar detection means. This detection means which, for example, may be an air bead, crashes against the rigid bar during a collision with a person or an object.

L'écrasement du moyen de détection contre la barre rigide est converti en un signal électrique qui entraîne un arrêt du rideau et sa re-ouverture immédiate.The crushing of the detecting means against the rigid bar is converted into an electrical signal which causes the curtain to stop and re-open immediately.

Dans le cas d'un boudin d'air qui entre en collision avec une personne, celui-ci s'écrase contre la barre rigide inférieure du rideau. Cet écrasement provoque une surpression dans le boudin qui est détectée par un pressostat.In the case of an air coil that collides with a person, it collapses against the lower rigid bar of the curtain. This crushing causes an overpressure in the coil which is detected by a pressure switch.

Ce type de système de sécurisation présente à l'usage de nombreux inconvénients.This type of security system has the use of many disadvantages.

En premier lieu, ils ne peuvent détecter que des objets situés accidentellement dans le plan d'ouverture du rideau, c'est à dire à la verticale de la barre inférieure.First, they can only detect objects accidentally located in the plane of opening of the curtain, that is to say vertically of the lower bar.

Un second inconvénient majeur est que les moyens de détection se trouvent en partie basse du rideau en dessous de la barre rigide inférieure. Par conséquent, ces moyens de détection sont exposés à de nombreuses agressions. La première agression est le contact répété avec le sol dans le cas d'une porte à repliement ou enroulement vertical.A second major disadvantage is that the detection means are in the lower part of the curtain below the lower rigid bar. Consequently, these detection means are exposed to numerous attacks. The first aggression is the repeated contact with the ground in the case of a folding door or vertical winding.

Cela conduit à une usure extrêmement rapide de ces moyens de détection. En outre, lorsque la porte est ouverte, les moyens de détections peuvent être accrochés et détériorés par des engins passant au travers de la porte. En cas de dysfonctionnement du système de détection, le rideau ne peut que descendre en écrasant la personne ou l'objet qui se trouve sur sa trajectoire et être lui-même détérioré le cas échéant.This leads to extremely rapid wear of these detection means. In addition, when the door is open, the detecting means can be hooked and damaged by gear passing through the door. In case of malfunction of the detection system, the curtain can only descend by crushing the person or the object in its path and be itself damaged if necessary.

Un inconvénient supplémentaire de ce type de moyens de détection est que, dans le cas d'une collision selon une composante horizontale, la collision se fait entre une personne, par exemple, la tête de cette personne et la barre inférieure qui est lourde et rigide, ce qui peut occasionner des blessures pouvant être graves. De même, une collision avec un engin peut également avoir des conséquences importantes pour l'objet ou l'engin traversant la porte, ainsi que pour les moyens de détection de contact qui sont directement exposés puisqu'ils sont suspendus à la barre inférieure.An additional disadvantage of this type of detection means is that, in the case of a collision according to a horizontal component, the collision is between a person, for example, the head of this person and the lower bar which is heavy and rigid. , which can cause serious injury. Likewise, a collision with a machine can also have important consequences for the object or the vehicle passing through the door, as well as for the contact detection means that are directly exposed since they are suspended at the lower bar.

De plus, ces moyens de détection présentent un temps de réponse pouvant être relativement long, ce qui les rend inefficaces lorsqu'ils équipent des portes rapides à rideau souple. En effet, les moyens de détection sont placés dans une bande souple suspendue sous la barre inférieure ; la faible épaisseur de cette bande qui gaine les moyens de détection fait que cette bande est écrasée avant que le moteur d'entraînement du rideau s'arrête. En dépit de l'action des moyens de détection, un contact se produit inévitablement avec la barre rigide inférieure, ce qui peut avoir des conséquences éventuellement graves.In addition, these detection means have a response time that can be relatively long, which makes them ineffective when they equip doors with flexible curtain. Indeed, the detection means are placed in a flexible band suspended below the lower bar; the small thickness of this band which sheaths the detection means causes this band to be crushed before the curtain drive motor stops. Despite the action of the detection means, contact inevitably occurs with the lower rigid bar, which can have potentially serious consequences.

Un but de l'invention est donc de proposer une porte rapide à rideau souple ayant des moyens de détection de collision entre un rideau souple et une personne ou un objet, qui soient fiables et largement insensibles aux usures.An object of the invention is therefore to provide a fast flexible curtain door having collision detection means between a curtain flexible and a person or an object, which are reliable and largely insensitive to wear.

Un autre but de l'invention est de proposer une porte rapide à rideau souple ayant des moyens de détection qui peuvent détecter une collision se produisant selon une direction horizontale entre un rideau souple et une personne ou un objet.Another object of the invention is to provide a flexible curtain fast door having detection means which can detect a collision occurring in a horizontal direction between a flexible curtain and a person or object.

De manière connue en soi une porte rapide comprend :

  • une structure comprenant des montants et un élément transversal permettant de guider un rideau,
  • des moyens électromécaniques supportés par la structure permettant de manoeuvrer le rideau entre une position d'ouverture et une position de fermeture.
le rideau présentant, à son extrémité libre, un élément de lestage et d'étanchéification,In known manner a fast door comprises:
  • a structure comprising uprights and a transverse element for guiding a curtain,
  • electromechanical means supported by the structure for operating the curtain between an open position and a closed position.
the curtain having, at its free end, a weighting and sealing element,

Selon l'invention, la porte présente des moyens de détection d'obstacle portés au moins en partie par l'élément de renfort, lesdits moyens de détection d'obstacle étant adjacents à l'élément de lestage et d'étanchéification et situés en amont de celui-ci, sur la trajectoire de fermeture du rideau, entre l'élément de renfort et l'élément de lestage et d'étanchéification, et en ce que lesdits moyens de détection d'obstacle sont intégrés à l'intérieur de la partie inférieure du rideau.According to the invention, the door has obstacle detection means carried at least in part by the reinforcing element, said obstacle detection means being adjacent to the ballast and sealing element and located upstream. of the latter, on the closing path of the curtain, between the reinforcing element and the ballast and sealing element, and in that said obstacle detection means are integrated inside the part. bottom of the curtain.

Ainsi, l'idée à la base de l'invention est d'intégrer dans le rideau même des moyens de détection d'obstacle pour sécuriser le fonctionnement de la porte.Thus, the idea underlying the invention is to integrate in the curtain itself obstacle detection means to secure the operation of the door.

Ceci est réalisé en les plaçant en amont de l'élément de lestage et d'étanchéification. Par, en amont, on entend au dessus de l'élément de lestage et d'étanchéification dans le cas d'une porte à ouverture verticale, le terme en amont devant être compris par rapport à la trajectoire de fermeture du rideau. Les moyens de détection sont protégés mécaniquement par l'élément de lestage et d'étanchéification. Ils sont déclenchés, le cas échéant, par la déformation de l'élément de lestage et d'étanchéification lorsque le rideau rentre en contact avec un obstacle se trouvant sous le rideau lorsqu'il se referme.This is done by placing them upstream of the ballast and sealing element. By, upstream, is meant above the ballast element and sealing in the case of a vertical opening door, the upstream term to be understood with respect to the closing path of the curtain. The detection means are mechanically protected by the ballast and sealing element. They are triggered, if necessary, by the deformation of the ballast element and sealing when the curtain comes into contact with an obstacle under the curtain when it closes.

On note de plus que, dans le cas où l'élément de lestage et d'étanchéification est flexible, il se déforme et déclenche les moyens de détection, lors d'une collision quelle que soit la direction selon laquelle la collision se produit. En d'autres termes, une collision selon une composante verticale, horizontale ou selon une composante d'orientation quelconque sera détectée.Note further that, in the case where the ballast and sealing element is flexible, it deforms and triggers the detection means, in a collision regardless of the direction in which the collision occurs. In other words, a collision in a vertical, horizontal or any orientation component will be detected.

Selon une forme de réalisation préférée de l'invention, les moyens de détection d'obstacle présentent une position de fonctionnement normal du rideau dans laquelle les moyens de détection sont parallèles à l'élément de lestage et d'étanchéification et une position de fonctionnement anormal du rideau dans laquelle les moyens de détection d'obstacle sont déviés ou interrompus de leur axe parallèle à l'élément de lestage et d'étanchéification par une déformation ou un déplacement de l'élément de lestage et d'étanchéification lorsqu'il rencontre un obstacle.According to a preferred embodiment of the invention, the obstacle detection means have a normal operating position of the curtain in which the detection means are parallel to the ballast and sealing element and an abnormal operating position. of the curtain in which the obstacle detection means are deflected or interrupted from their axis parallel to the weighting and sealing element by deformation or displacement of the ballast and sealing element when it meets a obstacle.

Selon une forme de réalisation préférée de l'invention, le rideau présente au moins un élément de renfort parallèle à l'élément de lestage et d'étanchéification, les moyens de détection étant situés entre l'élément de renfort et l'élément de lestage et d'étanchéification. Cette disposition fait clairement ressortir l'intégration des moyens de détection dans le rideau.According to a preferred embodiment of the invention, the curtain has at least one reinforcing element parallel to the ballast and sealing element, the detection means being located between the reinforcing element and the ballast element. and sealing. This arrangement clearly shows the integration of the detection means in the curtain.

Pour régler la sensibilité des moyens de détection notamment en fonction la vitesse du rideau, il est prévu que les moyens de détection d'obstacle sont situés à une distance paramétrable de l'élément de lestage et d'étanchéification.To adjust the sensitivity of the detection means in particular according to the speed of the curtain, it is expected that the obstacle detection means are located at a configurable distance from the ballast element and sealing.

Dans une forme de réalisation des moyens de détection d'obstacle, ceux-ci sont constitués par une cellule émettrice d'un faisceau supportée à une extrémité de l'élément de renfort et une cellule réceptrice du faisceau supportée à l'autre extrémité de la barre de renfort, le faisceau entre la cellule émettrice et la cellule réceptrice étant parallèle à l'élément de lestage et d'étanchéification, et étant susceptible d'être coupé par une déformation de l'élément de lestage et d'étanchéification lorsqu'il rencontre un obstacle.In one embodiment of the obstacle detection means, these consist of a beam-emitting cell supported at one end of the reinforcing element and a beam-receiving cell supported at the other end of the beam. reinforcing bar, the beam between the emitting cell and the receiving cell being parallel to the ballast and sealing element, and being capable of being cut by deformation of the ballast and sealing element when meets an obstacle.

Dans une forme de réalisation, l'élément de lestage et d'étanchéification comprend, sur sa face en regard du faisceau à chacune de ses extrémités, au moins un drapeau qui vient couper le faisceau, lorsque l'élément de lestage et d'étanchéification est déformé lorsqu'il rencontre un obstacle.In one embodiment, the weighting and sealing element comprises, on its face facing the beam at each of its ends, at least one flag that cuts the beam, when the weighting element and sealing is deformed when he encounters an obstacle.

Selon une possibilité chaque extrémité de la barre flexible de renfort reçoit une chandelle sur laquelle est fixée la cellule réceptrice et la cellule émettrice.According to one possibility each end of the flexible reinforcing bar receives a candle on which is fixed the receiving cell and the transmitting cell.

Pour permettre de régler l'entraxe entre l'élément de lestage et d'étanchéification et le faisceau, chaque chandelle présente plusieurs emplacements de réception des cellules émettrice et réceptrice.In order to adjust the distance between the weighting and sealing element and the beam, each candle has several receiving locations of the transmitting and receiving cells.

Selon les cas, le faisceau défini entre la cellule émettrice et la cellule réceptrice est un faisceau du groupe constitué par un faisceau optique, un faisceau acoustique, un faisceau laser, un faisceau radar à angle de balayage étroit.According to the case, the beam defined between the emitting cell and the receiving cell is a beam of the group consisting of an optical beam, an acoustic beam, a laser beam, a narrow scanning angle radar beam.

Dans une autre forme de réalisation des moyens de détection d'obstacle, ceux-ci sont constitués par un câble tendu parallèlement à l'élément de lestage et d'étanchéification, susceptible d'être déformé par une déformation ou un déplacement de l'élément de lestage et d'étanchéification lorsqu'il rencontre un obstacle.In another embodiment of the obstacle detection means, these consist of a cable stretched parallel to the ballast and sealing element, capable of being deformed by deformation or displacement of the element. ballast and sealing when encountering an obstacle.

Pour le maintien du câble, la barre de renfort présente à chacune de ses extrémités une chandelle, le câble étant tendu entre les deux chandelles.For the maintenance of the cable, the reinforcing bar has at each of its ends a candle, the cable being stretched between the two candles.

On note selon une forme de réalisation que le câble est maintenu à une chandelle par un ressort et à l'autre chandelle par un contact à tirette pouvant se déclencher en cas de déformation du câble.It is noted according to one embodiment that the cable is held by a candle by a spring and the other candle by a pull contact that can be triggered in case of deformation of the cable.

Dans une forme d'exécution, les moyens de détection sont reliés par une liaison filaire à l'électronique ou l'électromécanique de commande des moyens électromécaniques d'entraînement du rideau.In one embodiment, the detection means are connected by a wire connection to the control electronics or electromechanics of the electromechanical means for driving the curtain.

L'invention concerne plusieurs types de porte notamment :

  • la porte est une porte à enroulement présentant un rideau à tablier unique,
  • la porte est une porte à repliement présentant un rideau à tablier unique,
  • la porte est une porte à repliement présentant un rideau à double tablier.
The invention relates to several types of door including:
  • the door is a roll-up door with a single apron curtain,
  • the door is a folding door with a single apron curtain,
  • the door is a folding door with a double apron curtain.

De façon préférée, l'élément de lestage et d'étanchéification est constitué d'un ressort recouvert d'une gaine de mousse libre à ses extrémités ou ayant à chacune de ses extrémités un embout pouvant s'engager dans une glissière d'un montant. Cette forme de réalisation de l'élément de lestage et d'étanchéification est intéressante dans la mesure où cet élément avec cette structure peut se déformer aussi bien dans une direction confondue avec le plan du rideau que dans une direction perpendiculaire au plan du rideau ainsi que toute autre direction comprise entre le plan de rideau et un plan perpendiculaire. L'élément de lestage et d'étanchéification pourrait également être constitué par un boudin rempli de sable, de grenaille ou de tout autre matériau de remplissage assurant sa déformabilité.Preferably, the ballast and sealing element consists of a spring covered with a free foam sheath at its ends or having at each of its ends a tip that can engage in a slide of a post . This embodiment of the ballast and sealing element is interesting in that this element with this The structure may deform both in a direction coincident with the plane of the curtain and in a direction perpendicular to the plane of the curtain as well as any other direction between the curtain plane and a perpendicular plane. The weighting and sealing element could also be constituted by a bead filled with sand, grit or any other filling material ensuring its deformability.

Dans une forme de réalisation, la partie d'extrémité du rideau présente une bâche en U venant se fixer sur les faces extérieures du rideau qui intègre un fourreau dans lequel l'élément de lestage et d'étanchéification est engagé.In one embodiment, the end portion of the curtain has a U-shaped sheet attached to the outer faces of the curtain which incorporates a sleeve in which the ballast element and sealing is engaged.

Pour éviter des déclenchements parasites c'est à dire non consécutifs à une collision des moyens de détections avec un obstacle, la partie inférieure de la porte est équipée d'écarteurs situés autour des moyens de détection.To avoid parasitic triggering that is to say not consecutive to a collision of the detecting means with an obstacle, the lower part of the door is equipped with spacers located around the detection means.

En terme d'action consécutive à un incident, le déclenchement des moyens de détection génère au moins une action du groupe constitué par :

  • un arrêt du rideau,
  • une ouverture du rideau,
  • l'émission d'un signal,
  • l'émission d'un signal sonore,
  • l'émission d'un signal lumineux,
  • l'émission d'un signal hertzien,
  • le déclenchement d'une action,
  • le déclenchement d'une information,
  • une incrémentation d'un historique d'incidents.
In terms of action following an incident, the triggering of the detection means generates at least one action of the group consisting of:
  • a curtain stop,
  • an opening of the curtain,
  • the emission of a signal,
  • the emission of a sound signal,
  • the emission of a light signal,
  • the emission of a wireless signal,
  • triggering an action,
  • triggering information,
  • an incrementation of an incident history.

Ce groupe n'est pas limitatif et l'action engagée pourrait encore être l'envoi d'un message électronique ou téléphonique, la mise en action d'un caméra ou d'un appareil photographique.This group is not limiting and the action could still be the sending of an electronic or telephone message, the setting in action of a camera or a camera.

Selon une possibilité, l'élément de renfort situé en amont de l'élément de lestage et d'étanchéification est guidé à l'une au moins de ses extrémités en fonctionnement normal de la porte.According to one possibility, the reinforcing element located upstream of the ballast and sealing element is guided at least at one of its ends during normal operation of the door.

De façon avantageuse, l'élément de renfort est constitué par un barre souple présentant une flexibilité d'ensemble lui permettant de ne pas subir de déformation permanente en cas de collision.Advantageously, the reinforcing element is constituted by a flexible bar having overall flexibility allowing it to not undergo permanent deformation in the event of a collision.

Dans le cas d'une porte à rideau souple à deux tabliers, l'élément de renfort est constitué des deux barres parallèles reliées par des entretoises.In the case of a flexible curtain door with two aprons, the reinforcing element consists of two parallel bars connected by spacers.

Avantageusement, les moyens de détections d'obstacle sont intégrés à l'intérieur de la partie inférieure du rideau.Advantageously, the obstacle detection means are integrated inside the lower part of the curtain.

Pour sa bonne compréhension, l'invention est décrite en référence au dessin ci annexé représentant, à titre d'exemple non limitatif, plusieurs types de rideaux intégrant des moyens de détection d'obstacle selon celle-ci.

Comme le montrent les figures, les moyens de détection d'obstacle peuvent être inclus à des portes rapides à rideau souple. De manière générale, il s'agit de portes ayant une structure comprenant des montants et un élément transversal permettant de guider le rideau, et des moyens électromécaniques (moteur électrique, réducteur, électronique ou électromécanique de commande) supportés par la structure permettant de manoeuvrer le rideau entre une position d'ouverture et une position de fermeture. La structure de ces portes est largement connues et ne sera pas décrite plus avant. On précisera néanmoins que certaines portes rapides sont équipées d'un rideau qui présente à son extrémité libre un élément de lestage et d'étanchéification. Cet élément de lestage et d'étanchéification flexible a pour fonction d'assurer une tension du rideau et lorsque la porte est fermée d'assurer un bonne étanchéité de la porte en s'écrasant contre le sol sans être abîme par les contacts répétés avec le sol.As shown in the figures, the obstacle detection means may be included in flexible curtain gates. In general, these are doors having a structure comprising uprights and a transverse element for guiding the curtain, and electromechanical means (electric motor, reducer, electronic or electromechanical control) supported by the structure for operating the curtain. curtain between an open position and a closed position. The structure of these doors is widely known and will not be described further. It should be noted however that some high speed doors are equipped with a curtain which has at its free end a ballast and sealing element. This element ballast and flexible sealing has the function of ensuring tension of the curtain and when the door is closed to ensure a good seal of the door by crashing against the ground without being damaged by the repeated contacts with the ground.

Par simplification, il est précisé que les éléments qui se retrouvent dans les différentes formes de réalisation sont désignés par les mêmes références numériques.For simplicity, it is specified that the elements that are found in the various embodiments are designated by the same reference numerals.

Pour la description de l'invention, on se référera tout d'abord à la figure 1.For the description of the invention, reference will first be made to the figure 1 .

Celle-ci représente la partie inférieure d'une porte à repliement à rideau 2 double. Bien entendu, la partie supérieure de cette porte comprend une motorisation électrique qui permet de faire monter et descendre ce rideau.This represents the lower part of a double curtain folding door. Of course, the upper part of this door includes an electric motor that can raise and lower the curtain.

Sur la partie inférieure de cette porte, on peut voir que le rideau 2 présente deux tabliers 4 et 5 qui portent chacun une barre de raidissement horizontale 7 et 8. Ces deux barres de raidissement 7,8 sont reliées entre elles par une entretoise 9 de liaison que l'on peut voir clairement sur la figure 1.On the lower part of this door, it can be seen that the curtain 2 has two aprons 4 and 5 which each carry a horizontal stiffening bar 7 and 8. These two stiffening bars 7, 8 are interconnected by a spacer 9 of connection that can be clearly seen on the figure 1 .

A l'extrémité du rideau, il est prévu une bâche 10 en U qui est fixée à chacun des tabliers 7,8. Cette bâche 10 est généralement réalisée dans un matériau épais résistant aux contacts répétés avec le sol. La bâche 10 en U reçoit un fourreau 12 dans lequel est glissé un élément de lestage et d'étanchéification 13. Cet élément de lestage et d'étanchéification 13 comprend deux masselottes 14 de lest à chacune des extrémités de la barre. Un ressort 15 est disposé entre ces masselottes 14 de lest, le tout étant engagé dans une gaine de mousse 16. On note également que l'élément de lestage et d'étanchéification 13 présente des embouts de guidage 17 qui peuvent venir s'engager dans des glissières dont les montants 18 de la porte sont équipés.At the end of the curtain, there is provided a U-shaped sheet 10 which is fixed to each of the aprons 7,8. This sheet 10 is generally made of a thick material resistant to repeated contact with the ground. The U-shaped sheet 10 receives a sheath 12 in which is slid a ballast and sealing element 13. This weighting and sealing element 13 comprises two ballast weights 14 at each end of the bar. A spring 15 is disposed between these ballast weights 14, the whole being engaged in a foam sheath 16. It is also noted that the weighting and sealing element 13 has guide tips 17 which can engage in slides whose 18 amounts of the door are equipped.

Lorsque l'on se réfère à la figure 2, on peut voir que le rideau est équipé d'une chandelle 20 qui est boulonnée dans l'entretoise reliant les deux raidisseurs.When referring to the figure 2 it can be seen that the curtain is equipped with a candle 20 which is bolted into the spacer connecting the two stiffeners.

Il doit être noté que le rideau 2 présente une structure symétrique et l'on retrouve la même construction à l'autre extrémité des barres de raidissement 7,8.It should be noted that the curtain 2 has a symmetrical structure and the same construction is found at the other end of the stiffening bars 7,8.

Le point tout à fait caractéristique de ce rideau est que la chandelle supporte une cellule 21 qui émet un faisceau 23 optique parallèle et en amont de l'élément de lestage et d'étanchéification 13. En face de cette cellule 21 émettrice, la seconde chandelle support est équipée pour sa part d'une cellule réceptrice. Dans une autre possibilité, l'une des chandelles 20 est équipée d'une cellule émettrice/réceptrice tandis que l'autre chandelle reçoit simplement une cellule passive de renvoie du faisceau. La cellule réceptrice est reliée par une liaison filaire 22 à l'électronique ou l'électromécanique de commande du rideau 2.The most characteristic point of this curtain is that the candle supports a cell 21 which emits an optical beam 23 parallel to and upstream of the ballast and sealing element 13. In front of this emitting cell 21, the second candle support is equipped for its part with a receiving cell. In another possibility, one of the candles 20 is equipped with a transmitting / receiving cell while the other candle simply receives a passive beam return cell. The receptor cell is connected by a wired link 22 to the control electronics or electromechanics of the curtain 2.

On note, par ailleurs, que l'élément de lestage et d'étanchéification 13 reçoit, sur sa face qui est en regard des chandelles 20 supports, à chacune de ses extrémités un drapeau 24 de détection qui est constitué par un profilé en L.It should be noted, moreover, that the weighting and sealing element 13 receives, on its face which is opposite the support candles, at each of its ends a detection flag 24 which is constituted by an L-shaped section.

Le fonctionnement du dispositif de détection est donc le suivant. Lorsque l'élément de lestage et d'étanchéification 13 rencontre au cours de sa descente un obstacle, il se déforme puisqu'il est constitué pour sa part essentielle d'un ressort et d'une gaine de mousse. La déformation de l'élément de lestage et d'étanchéification 13 modifie l'assiette d'un ou des deux drapeaux 24 qui viennent alors couper le faisceau qui est normalement parallèle à l'élément de lestage et d'étanchéification 13. Le faisceau 23 étant coupé, il est envoyé un signal à l'électronique ou l'électromécanique de commande de la porte qui donne alors l'ordre, d'une part, d'arrêter la descente du rideau, et d'autre part, de faire remonter celui-ci.The operation of the detection device is therefore as follows. When the weighting and sealing element 13 encounters during its descent an obstacle, it deforms since it consists essentially of a spring and a foam sheath. The deformation of the weighting and sealing element 13 modifies the attitude of one or both flags 24 which then cut off the beam which is normally parallel to the weighting and sealing element 13. The beam 23 being cut, it is sent a signal to the electronics or the electromechanical control of the door which then gives the order, on the one hand, to stop the descent of the curtain, and on the other hand, to go up this one.

On voit donc que, lors d'une collision par exemple avec une personne, cette collision se fait avec un élément qui est essentiellement souple et qui, au cours de sa déformation, donne un ordre de remontée du rideau.It is thus seen that, in a collision for example with a person, this collision is made with an element which is essentially flexible and which, during its deformation, gives an order of raising of the curtain.

On remarque, de façon tout à fait intéressante, que la chandelle 24 présente deux zones d'accueil 26,27 pour la cellule émettrice 21 du faisceau 23, si bien que l'on peut faire varier l'entraxe existant entre l'élément de lestage et d'étanchéification et l'axe du faisceau. Ainsi, dans le cas d'une porte lente, on pourra avoir un entraxe relativement important, tandis que dans le cas d'une porte descendant avec une grande vitesse, il sera nécessaire d'avoir un dispositif sensible et, dans ce cas là, l'entraxe entre l'élément de lestage et d'étanchéification et l'axe du faisceau sera le plus faible possible pour avoir une détection la plus rapide possible.It is remarkably interesting to note that the candle 24 has two reception zones 26, 27 for the emitting cell 21 of the beam 23, so that the distance between the element of ballast and sealing and beam axis. Thus, in the case of a slow door, it may have a relatively large distance, while in the case of a door with a high speed, it will be necessary to have a sensitive device and, in this case, the spacing between the ballast and sealing element and the beam axis will be as small as possible for the fastest possible detection.

Les figures 3 et 4 montrent le dispositif équipant une porte à enroulement vertical. Les moyens de détection sont tout à fait comparables à ceux qui viennent d'être décrits.The Figures 3 and 4 show the device equipping a vertical rolling door. The detection means are quite comparable to those just described.

Comme le montre la figure 3, une porte à enroulement vertical présente un rideau ayant un tablier 28 unique qui, au niveau de son extrémité inférieure, présente une bâche en U 10 qui vient se fixer sur chacune des faces du tablier 28. Un fourreau 12 est formé dans la bâche en U dans lequel est engagé un élément de lestage et d'étanchéification 13 ayant la même structure que celle décrite précédemment, c'est-à-dire un élément présentant une certaine masse pour lester le rideau, mais présentant une certaine souplesse pour se déformer lors d'un choc.As shown in figure 3 a vertical rolling door has a curtain having a single apron 28 which, at its lower end, has a U-shaped sheet 10 which is fixed on each of the faces of the apron 28. A sleeve 12 is formed in the tarpaulin. U in which is engaged a weighting and sealing element 13 having the same structure as that described above, that is to say an element having a certain mass to ballast the curtain, but having a certain flexibility to deform when of a shock.

La figure 3 montre que le rideau intègre une barre de raidissement 29 transversale, cette barre de raidissement 29 transversale étant un élément classique des rideaux de porte à enroulement verticale. Cette barre de raidissement supporte, à chacune de ses extrémités, une chandelle 20 ; l'une de ces chandelles reçoit une cellule émettrice 21, tandis que l'autre reçoit une cellule réceptrice. Ces deux cellules 21 définissent donc un axe de faisceau 23 parallèle à l'axe de l'élément de lestage et d'étanchéification inférieur.The figure 3 shows that the curtain incorporates a transverse stiffening bar 29, this transverse stiffening bar 29 being a conventional element of vertical rolling door curtains. This bar of stiffening supports, at each of its ends, a candle 20; one of these candles receives a transmitting cell 21, while the other receives a receiving cell. These two cells 21 thus define a beam axis 23 parallel to the axis of the ballast element and lower sealing.

En fonctionnement normal, l'axe du faisceau 23 est strictement parallèle à l'axe de l'élément de lestage et d'étanchéification 13.In normal operation, the axis of the beam 23 is strictly parallel to the axis of the weighting and sealing element 13.

Comme on peut le voir sur la figure, on note que l'élément de lestage et d'étanchéification supporte, à chacune de ses extrémités, un drapeau 24 c'est-à-dire un profilé en forme de L. Lorsque l'élément de lestage et d'étanchéification 13 rencontre un obstacle, il se déforme et le drapeau 24 vient couper le faisceau optique. La coupure de ce faisceau 23 optique est signalée à l'électronique ou l'électromécanique de commande de la porte qui ordonne une remontée du rideau.As can be seen in the figure, it is noted that the weighting and sealing element supports, at each of its ends, a flag 24, that is to say an L-shaped profile. The ballast 13 meets an obstacle, it deforms and the flag 24 cuts the optical beam. The cutoff of this optical beam 23 is signaled to the electronics or the electromechanical control of the door which orders a raising of the curtain.

Il doit être noté que l'électronique ou l'électromécanique de commande peut déclencher tout autre signal visuel ou sonore permettant d'alerter d'un accident. En outre, un comptage des accidents peut être fait pour connaître l'historique de la porte.It should be noted that the control electronics or electromechanics may trigger any other visual or audible signal to alert an accident. In addition, an accident count can be done to know the history of the door.

La figure 5 montre une porte fonctionnant selon un principe différent, qui ne fait pas partie de l'invention, dans la mesure où le rideau 2 s'efface latéralement entre sa position d'ouverture et sa position de fermeture.The figure 5 shows a door operating according to a different principle, which is not part of the invention, insofar as the curtain 2 is laterally erased between its open position and its closed position.

La structure des moyens de détection est tout à fait comparable à celle mise en oeuvre pour des portes à repliement ou à enroulement vertical. En effet, on retrouve dans cette porte un élément de lestage et d'étanchéification 13 qui, bien entendu dans le cas présent, est orienté selon la direction verticale, cet élément de lestage et d'étanchéification présente une structure tout à fait comparable à celle de l'élément de lestage et d'étanchéification des portes précédemment décrites, c'est-à-dire un ressort gainé de mousse.The structure of the detection means is quite comparable to that used for folding doors or vertical winding. Indeed, there is in this door a ballast element and sealing 13 which, of course in this case, is oriented in the vertical direction, this weighting element and sealing has a structure quite comparable to that of the weighting and sealing element of the previously described doors, that is to say a foam-wrapped spring.

Une barre de raidissement 30 parallèle à la barre d'extrémité supporte deux chandelles 24, l'une étant équipée d'une cellule émettrice 21, l'autre étant équipée d'une cellule réceptrice, de telle sorte qu'un faisceau 23 parallèle à la barre d'extrémité soit défini entre ces deux cellules.A stiffening bar 30 parallel to the end bar supports two candles 24, one being equipped with an emitter cell 21, the other being equipped with a receiving cell, so that a beam 23 parallel to the end bar is defined between these two cells.

Lorsque le rideau 2 entre en collision avec un obstacle, que ce soit une personne ou un objet, l'élément de lestage et d'étanchéification 13 se déforme et l'un ou les drapeaux 24 vient couper le faisceau 23 défini entre les deux cellules, cela déclenche alors au niveau de l'électronique ou l'électromécanique de commande une action appropriée et prédéterminée qui est généralement l'arrêt du moteur et l'ouverture de la porte accompagné éventuellement d'un signal sonore ou visuel. Si l'on a représenté sur le dessin une porte à effacement latéral ayant un unique rideau, il est bien entendu tout à fait envisageable d'équiper d'un dispositif de détection de contact une porte à effacement latéral ayant deux rideaux souples.When the curtain 2 collides with an obstacle, whether it is a person or an object, the weighting and sealing element 13 deforms and one or the flags 24 cuts off the beam 23 defined between the two cells. , that triggers then at the level of electronics or the electromechanical control a suitable and predetermined action which is usually the engine stop and the opening of the door possibly accompanied by an audible or visual signal. If there is shown in the drawing a side erase door having a single curtain, it is of course quite conceivable to equip a contact detection device with a side erase door having two flexible curtains.

Il doit être noté que le dispositif de détection selon l'invention peut prendre une autre forme de réalisation représenté à la figure 6 puisqu'il est possible de prévoir, parallèlement à l'axe de l'élément de lestage et d'étanchéification, un câble 30 qui, à l'une de ses extrémités est retenu par un ressort 31 à une chandelle 20 support et, à son autre extrémité, est retenu par la chandelle support par l'intermédiaire d'un contact à tirette 32.It should be noted that the detection device according to the invention can take another embodiment shown in FIG. figure 6 since it is possible to provide, parallel to the axis of the weighting and sealing element, a cable 30 which at one of its ends is retained by a spring 31 to a support candle and, at its other end, is retained by the support candle via a pull contact 32.

Lors d'une déformation de l'élément de lestage et d'étanchéification 13 consécutive à une collision avec un obstacle, l'élément de lestage et d'étanchéification vient en contact du câble et en modifie la tension. Cette modification de tension se transcrit au niveau du contact à tirette 32 par un signal électrique qui est transmis à l'électronique ou l'électromécanique de commande qui, là encore, prend l'action prédéterminée appropriée.During deformation of the weighting and sealing element 13 following a collision with an obstacle, the weighting and sealing element comes into contact with the cable and modifies the voltage. This voltage change is transcribed at the pull contact 32 by an electrical signal which is transmitted to the control electronics or electromechanics which, again, takes the appropriate predetermined action.

La figure 7 illustre une autre forme de réalisation des moyens de détection d'obstacles dans laquelle une cellule 21 est reliée à une barre de renfort transversale 29 par une chandelle 24. Dans la forme de réalisation illustrée la chandelle 24 comprend deux supports 34 symétriques qui présentent chacun une partie concave pouvant venir enserrer la barre de renfort transversale 29. Les deux supports 34 enserrent, par ailleurs, une platine 35. La platine 35 présente, comme on peut le voir sur la figure 7 deux tiges filetées 37 ; ces tiges filetées ont pour fonction de recevoir un ferrure 38. On note que la ferrure 38 sur laquelle est fixée la cellule 21 présente une lumière oblongue 39 qui peut être engagée sur la tige filetées 37. Cette disposition permet de régler la position de la cellule 21 par rapport à l'élément 13. Bien entendu, une autre chandelle symétrique à celle qui vient d'être décrite peut être placée à l'autre extrémité de la barre de renfort transversale 29.The figure 7 illustrates another embodiment of the obstacle detection means in which a cell 21 is connected to a transverse reinforcement bar 29 by a candle 24. In the illustrated embodiment the candle 24 comprises two symmetrical supports 34 which each have a concave part that can come to grip the transverse reinforcing bar 29. The two supports 34 enclose, moreover, a plate 35. The plate 35 has, as can be seen on the figure 7 two threaded rods 37; these threaded rods have the function of receiving a fitting 38. Note that the bracket 38 on which is fixed the cell 21 has an oblong slot 39 which can be engaged on the threaded rod 37. This arrangement allows to adjust the position of the cell 21 of the element 13. Of course, another candle symmetrical to that just described can be placed at the other end of the transverse reinforcement bar 29.

L'invention, dans ses différentes formes de réalisation, présente donc les nombreux avantages indiqués. En effet, le dispositif de détection est totalement protégé puisqu'il se trouve, par rapport à l'élément de lestage et d'étanchéification ou la barre d'extrémité, sur sa face opposée à sa face qui est en contact du sol ou d'un montant. Cela contribue très favorablement à la fiabilité générale du dispositif.The invention, in its various embodiments, therefore has the many advantages indicated. Indeed, the detection device is completely protected since it is, relative to the weighting element and sealing or the end bar, on its face opposite to its face which is in contact with the ground or an amount. This contributes very favorably to the overall reliability of the device.

Par ailleurs, ce dispositif peut être très facilement paramétrable puisqu'il est prévu, dans les chandelles 20 de support, différentes positions pour les cellules émettrice et réceptrice.Furthermore, this device can be very easily parameterizable since it is provided in the support candles 20 different positions for the transmitter and receiver cells.

En outre, le dispositif fonctionne dans le cas d'une collision selon une direction autre que verticale par exemple horizontale ou selon une composante quelconque comprise entre ces deux directions puisque, dans tous les cas de figure qui ont été décrits, lorsque la barre inférieure est déplacée selon une composante horizontale, le faisceau ou le câble, selon les cas, est coupé ou est détendu, ce qui a pour effet de déclencher l'ouverture du rideau.In addition, the device operates in the case of a collision in a direction other than vertical for example horizontal or any component between these two directions since, in all cases that have been described, when the lower bar is moved in a horizontal component, the beam or cable, as appropriate, is cut or is relaxed, which has the effect of triggering the opening of the curtain.
