Description

La présente invention concerne les portes à rideau relevable du genre comportant un cadre formé par deux montants verticaux réunis à leurs parties supérieures par une traverse horizontale supportée par lesdits montants, et dans laquelle traverse est logé un arbre d'enroulement, soit du rideau lui-même constituant la porte relevable, soit de sangles permettant de relever le rideau avec un pliage en accordéon. Le rideau peut être renforcé par des barres horizontales. Les montants peuvent servir de glissières pour les bords du rideau, et le cas échéant, les extrémités des barres de renforcement. Pour obtenir un fonctionnement rapide et sans effort, on utilise un moteur électrique pour l'entraînement en rotation de l'arbre d'enroulement, en particulier un moteur frein, qui bloque la rotation quand il ne tourne pas.The present invention relates to liftable curtain doors of the kind comprising a frame formed by two vertical uprights joined at their upper parts by a horizontal crosspiece supported by said uprights, and in which crosspiece is housed a winding shaft, or curtain itself- even constituting the liftable door, or straps to raise the curtain with an accordion folding. The curtain can be reinforced with horizontal bars. The uprights can be used as slides for the edges of the curtain, and if necessary, the ends of the reinforcing bars. To obtain rapid and effortless operation, an electric motor is used to drive the winding shaft in rotation, in particular a brake motor, which blocks rotation when it is not turning.

Selon l'invention, la porte comporte un contrepoids constitué de plusieurs éléments disposés les uns sur les autres, les éléments étant de dimensions transversales différentes, croissant du bas vers le haut, des moyens étant prévus sur le trajet du contrepoids pour arrêter les éléments séparément à différentes hauteurs.According to the invention, the door comprises a counterweight made up of several elements arranged one on the other, the elements being of different transverse dimensions, increasing from the bottom upwards, means being provided on the path of the counterweight to stop the elements separately. at different heights.

Dans un mode de réalisation de l'invention, la porte comporte des moyens pour libérer le frein du moteur en cas de panne de courant.In one embodiment of the invention, the door includes means for releasing the engine brake in the event of a power failure.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée à titre d'exemple non limitatif en regards des dessins joints, et qui fera bien comprendre comment l'invention peut être réalisée. Sur les dessins :

  • la figure 1 est une vue en élévation, de face, d'une porte de manutention selon l'invention ; et
  • la figure 2 est une vue en détail montrant le moteur d'actionnement de la porte quand le capot de protection a été enlevé.
Other characteristics and advantages of the invention will appear during the description which follows, given by way of nonlimiting example with regard to the accompanying drawings, and which will make it clear how the invention can be implemented. In the drawings:
  • Figure 1 is an elevational front view of a handling door according to the invention; and
  • Figure 2 is a detail view showing the door actuating motor when the protective cover has been removed.

Le dispositif représenté à titre d'exemple sur la figure 1 comporte un cadre, ou portique, formé par deux montants verticaux 2, 3, réunis à leurs parties supérieures par une traverse horizontale 1 supportée par lesdits montants latéraux 2 et 3, qui servent aussi de glissières à une porte souple relevable 25 constituée par exemple par une feuille de matière plastique renforcée par des traverses horizontales 26 rigides ou flexibles élastiquement. La porte s'enroule sur un arbre horizontal supérieur entraîné en rotation par un un moteur électrique 5, monté verticalement dans le montant 2 du cadre de la porte, par l'intermédiaire d'un bloc de renvoi d'angle 6 formant réducteur, fixé à la partie supérieure du montant 2 ou à la traverse 1 et servant à la fois de support pour le moteur et de palier support pour l'arbre d'enroulement. Le fonctionnement du moteur dans un sens ou dans l'autre assure la montée et la descente de la porte rideau par enroulement et déroulement du rideau. Un autre palier supporte l'autre extrémité de l'arbre.The device shown by way of example in FIG. 1 comprises a frame, or gantry, formed by two vertical uprights 2, 3, joined at their upper parts by a horizontal cross member 1 supported by said lateral uprights 2 and 3, which also serve of slides to a flexible lifting door 25 constituted for example by a plastic sheet reinforced by horizontal crosspieces 26 rigid or elastically flexible. The door is wound on an upper horizontal shaft driven in rotation by an electric motor 5, mounted vertically in the upright 2 of the door frame, by means of an angle return block 6 forming a reduction gear, fixed at the upper part of the upright 2 or at the cross member 1 and serving both as a support for the motor and as a support bearing for the winding shaft. The operation of the motor in one direction or the other ensures the raising and lowering of the curtain door by winding and unwinding of the curtain. Another bearing supports the other end of the shaft.

Le fonctionnement ou l'arrêt du moteur électrique peut être commandé par actionnement d'un bouton poussoir, ou par tout système automatique, tel que système à cellule photoélectrique ou boucle de détection, etc.. Le moteur électrique peut avantageusement être du type moteur frein, bloquant le rideau en position relevée ou abaissée quand le moteur ne tourne pas. L'arrêt du rideau en position peut aussi être obtenu par des moyens mécaniques. Quand le moteur n'est pas sous tension, en cas de panne de courant par exemple, il est avantageux que le rideau puisse être monté ou baissé sans rencontrer de résistance notable de la part du moteur.The operation or stopping of the electric motor can be controlled by actuation of a push button, or by any automatic system, such as a photocell system or detection loop, etc. The electric motor can advantageously be of the brake motor type , blocking the curtain in the raised or lowered position when the engine is not running. Stopping the curtain in position can also be obtained by mechanical means. When the motor is not energized, in the event of a power failure for example, it is advantageous that the curtain can be raised or lowered without encountering significant resistance from the motor.

Quand l'alimentation électrique est normale, le moteur, quelque soit la manière dont il est commandé, fait monter ou descendre la porte rideau, et, par sa fonction frein à l'arrêt, maintient la porte dans une position relevée ou baissée, ou autre position intermédiaire, quand son alimentation est coupée, cependant qu'il reste sous tension pour le bon fonctionnement du frein. En cas de panne de courant sur l'ensemble de l'installation, le frein moteur est libéré, et l'arbre d'enroulement peut tourner librementWhen the electrical supply is normal, the motor, however it is controlled, raises or lowers the curtain door, and, by its stop brake function, keeps the door in a raised or lowered position, or another intermediate position, when its power is cut, while it remains energized for the proper functioning of the brake. In the event of a power failure throughout the installation, the engine brake is released and the winding shaft can rotate freely

L'extrémité opposée de l'arbre d'enroulement peut être fixée sur un module identique ou symétrique, lui-même fixé au cadre de la porte. Ce deuxième module porte l'arbre, et sur l'autre sortie, il peut porter un accessoire de fin de course, par exemple un ressort ou autre. Il peut en outre être prévu une autre sortie sur le module, pour l'enroulement du câble d'un contrepoids.The opposite end of the winding shaft can be fixed to an identical or symmetrical module, itself fixed to the door frame. This second module carries the shaft, and on the other output, it can carry an end-of-travel accessory, for example a spring or the like. Another output can also be provided on the module, for winding the cable of a counterweight.

Pour pouvoir accéder au moteur en vue de l'entretien, des réparations, etc., par exemple un remplacement, la partie supérieure de la face avant 14 du montant est découpée et un capot 15 amovible, pouvant être articulé en haut sur la traverse par exemple, est placé pour protéger le moteur. Une disposition analogue peut être prévue sur le deuxième montant, pour une raison de symétrie esthétique.To be able to access the engine for maintenance, repairs, etc., for example a replacement, the upper part of the front face 14 of the upright is cut out and a removable cover 15, which can be articulated at the top on the crossmember by example, is placed to protect the motor. A similar arrangement can be provided on the second upright, for reasons of aesthetic symmetry.

Les barres d'armature 26 du rideau sont de préférence souples de façon à sortir de la glissière sans déformation permanente, sous l'effet d'une sollicitation anormale, si par exemple un chariot percute le rideau avant qu'il ne soit complètement relevé.The reinforcing bars 26 of the curtain are preferably flexible so as to come out of the slide without permanent deformation, under the effect of abnormal stress, if for example a carriage strikes the curtain before it is completely raised.

On a représenté en trait interrompu sur la figure 2 une sortie supplémentaire 23 du bloc de transmission, en vue de l'enroulement d'un câble de contrepoids, abrité par un capotage 24. Le contrepoids peut être constitué de plusieurs éléments de tailles horizontales différentes pour rester accrochés à différentes hauteurs lors de la descente du contrepoids, et adapter la masse pesante de celui-ci au poids de la longueur de rideau déroulé. Dans ces conditions, il est possible d'avoir une hauteur d'équilibre au niveau d'arrêt d'un des contrepoids, hauteur permettant le passage en cas de secours.There is shown in broken lines in Figure 2 an additional output 23 of the transmission block, for the winding of a counterweight cable, sheltered by a cowling 24. The counterweight can be made up of several elements of different horizontal sizes to remain hung at different heights when lowering the counterweight, and adapt the heavy weight of the latter to the weight of the length of the curtain unrolled. Under these conditions, it is possible to have a balance height at the stop level of one of the counterweights, a height allowing passage in the event of an emergency.
