    • On a montré en figures 1 à 4 une porte de manutention 1 pour bâtiment industriel comportant deux montants latéraux et opposés 2 et 3 qui sont fixés contre les parois verticales d'une ouverture à obstruer. FIGS. 1 to 4 show a handling door 1 for an industrial building comprising two lateral and opposite uprights 2 and 3 which are fixed against the vertical walls of an opening to be blocked.

    Les montants opposés et verticaux 2 et 3 sont reliés entre eux dans la partie supérieure de la porte de manutention 1 par un tambour d'enroulement 4 protéger par un capot 5 et permettant, par l'intermédiaire de sangles de traction, le déplacement du rideau souple entre une position d'ouverture et une position de fermeture.The opposite and vertical uprights 2 and 3 are interconnected in the part upper of the handling door 1 by a winding drum 4 protect by a cover 5 and allowing, via traction straps, the displacement of the flexible curtain between an open position and a closing.

    Chaque montant vertical 2, 3 comporte sur sa face externe une glissière 6 formée par exemple de sangles 7, 8 permettant de guider le rideau souple et ses traverses horizontales lors des déplacements verticaux dudit rideau.Each vertical post 2, 3 has on its external face a slide 6 formed for example straps 7, 8 for guiding the flexible curtain and its horizontal crosspieces during vertical displacements of said curtain.

    Le tambour d'enroulement 4 est lié mécaniquement à l'une de ses extrémités à un motoréducteur-frein, non représenté, fixé dans la partie supérieure du montant vertical 2 et permettant les mouvements verticaux du rideau souple entre une position d'ouverture et une position de fermeture.The winding drum 4 is mechanically linked at one of its ends to a brake gear motor, not shown, fixed in the upper part of the upright vertical 2 and allowing the vertical movements of the flexible curtain between a open position and a closed position.

    Le tambour d'enroulement 4 est solidaire à l'opposée du motoréducteur d'une poulie 9 disposée dans la partie supérieure de montant 3 et qui est reliée par l'intermédiaire d'une courroie de traction 10 à un contrepoids 11 constitué, soit d'un seul élément, soit de plusieurs éléments empilés.The winding drum 4 is integral opposite the gear motor with a pulley 9 arranged in the upper upright 3 and which is connected by via a traction belt 10 to a counterweight 11 constituted, either of a single element, or of several elements stacked.

    La poulie 9 est fixée sur l'arbre de sortie 12 du tambour d'enroulement 4, tandis que la courroie 10 est solidaire, d'une part à l'une de ses extrémités de la poulie 9 pour pouvoir s'enrouler autour d'elle lors de la remonté de contrepoids 11, et d'autre part à son extrémité opposée à l'une des parois du montant vertical 3 par l'intermédiaire d'une platine 13.The pulley 9 is fixed to the output shaft 12 of the winding drum 4, while that the belt 10 is integral, on the one hand at one of its ends of the pulley 9 to be able to wrap around it when the counterweight 11 is raised, and on the other hand at its end opposite to one of the walls of the vertical upright 3 by via a plate 13.

    Cette dernière est fixée sur le montant vertical 3, juste en dessous de la poulie 9 afin que la courroie 10 forme entre ses deux points extrêmes de fixation une boucle passant par le contrepoids 11.The latter is fixed to the vertical upright 3, just below the pulley 9 so that the belt 10 forms between its two extreme points of attachment a loop passing through the counterweight 11.

    En effet, la courroie 10 est reliée au contrepoids 11 par l'intermédiaire d'un dispositif à galet 14 permettant le guidage et le centrage de ladite courroie dans la partie supérieure dudit contrepoids lors des ses déplacements verticaux en fonction du sens de rotation de la poulie 9.Indeed, the belt 10 is connected to the counterweight 11 by means of a roller device 14 for guiding and centering said belt in the upper part of said counterweight during its vertical displacements in depending on the direction of rotation of the pulley 9.

    Le contrepoids 11 est assujetti à un dispositif de guidage 15 permettant de guider ses mouvements à l'intérieur du montant vertical 3.The counterweight 11 is subject to a guiding device 15 making it possible to guide its movements inside the vertical upright 3.

    Le dispositif de guidage 15 est constitué de deux câbles 16, 17 tendus entre deux points extrêmes prévus respectivement dans la partie supérieure et inférieure du montant vertical 3.The guide device 15 consists of two cables 16, 17 stretched between two extreme points provided respectively in the upper and lower part of the vertical post 3.

    Le dispositif de guidage 15 comporte dans la partie supérieure du montant 3 et juste en dessous de la platine de fixation 13 permettant la fixation de l'une des extrémités de la courroie 10 un étrier de reprise 18 solidaire dudit montant. The guide device 15 comprises in the upper part of the upright 3 and just below the fixing plate 13 allowing the fixing of one of the ends of the belt 10 a recovery bracket 18 secured to said upright.

    L'étrier de reprise 18 présente un profil en forme de U déterminant avec la face verticale 19 du montant 3 un espace libre pour le passage de la courroie de traction 10.The recovery bracket 18 has a U-shaped profile determining with the face vertical 19 of the upright 3 a free space for the passage of the strap traction 10.

    L'étrier de reprise 18 comporte dans l'espace libre des doigts 32 et 33 reliant la face verticale 19 du montant 3 audit étrier pour pouvoir guider dans ses déplacements la courroie de traction 10.The recovery stirrup 18 comprises in the free space of the fingers 32 and 33 connecting the vertical face 19 of the upright 3 said stirrup to be able to guide in its displaces the traction belt 10.

    L'étrier de reprise 18 comporte deux ailes opposées 20, 21 qui sont percées chacune d'un alésage permettant le passage des extrémités supérieures de chaque câble 16 et 17 afin de former une boucle qui est solidarisée par un système de serrage 22.The recovery stirrup 18 has two opposite wings 20, 21 which are pierced each of a bore allowing the passage of the upper ends of each cable 16 and 17 in order to form a loop which is joined by a clamping system 22.

    Ainsi, les boucles solidaires de l'étrier de reprise 18 constituent les points supérieurs extrêmes de fixation des câbles 16 et 17 du dispositif de guidage 15.Thus, the loops integral with the recovery stirrup 18 constitute the points extreme upper fixing cables 16 and 17 of the guide device 15.

    La partie inférieure du montant 3 comporte au-dessus du sol du bâtiment industriel une assise horizontale 23 sur laquelle vient prendre appui le contrepoids 10 dans sa position la plus basse de sa course.The lower part of the upright 3 has above the ground of the building industrial a horizontal seat 23 on which the counterweight comes to bear 10 in its lowest position of its stroke.

    Les câbles 16 et 17 du dispositif de guidage 15 traversent l'assise horizontale 23 pour venir coopérer respectivement avec des tendeurs 24 et 25 qui sont disposés dans l'espace délimité par l'assise 23 et le sol du bâtiment.The cables 16 and 17 of the guide device 15 pass through the horizontal seat 23 to cooperate respectively with tensioners 24 and 25 which are arranged in the space delimited by the seat 23 and the floor of the building.

    Les tendeurs 24, 25 sont reliés à l'opposé de la fixation des câbles 16 et 17 par des anneaux de maintien 26, 27 à des axes 28, 29 solidaires d'une embase 30 formant la semelle d'appui du montant 3 sur le sol du bâtiment industriel.The tensioners 24, 25 are connected opposite to the fixing of the cables 16 and 17 by retaining rings 26, 27 to axes 28, 29 integral with a base 30 forming the support sole of the upright 3 on the floor of the industrial building.

    Ainsi, les câbles 16 et 17 comportent des boucles fermées par des systèmes de serrage 12 pour être solidaires des tendeurs 24, 25 constituant les points inférieurs extrêmes de fixation des câbles 16 et 17 du dispositif de guidage 15.Thus, cables 16 and 17 have loops closed by systems of tightening 12 to be integral with the tensioners 24, 25 constituting the points lower extremities for fixing the cables 16 and 17 of the guide device 15.

    Le dispositif de guidage 15, et plus particulièrement les câbles 16 et 17, sont reliés au contrepoids 11 par l'intermédiaire de vis à oeillet 31 disposées dans les parties supérieure et inférieure dudit contrepoids.The guide device 15, and more particularly the cables 16 and 17, are connected to the counterweight 11 by means of eyelet screws 31 arranged in the upper and lower parts of said counterweight.

    Ainsi, la structure du contrepoids 11 comporte dans sa partie supérieure et de part et d'autre du dispositif à galet 14, des vis à oeillet 31 recevant respectivement les câbles de guidage 16 et 17.Thus, the structure of the counterweight 11 has in its upper part and on the one hand and on the other side of the roller device 14, eyelet screws 31 respectively receiving the guide cables 16 and 17.

    Egalement, la structure du contrepoids 11 est solidaire dans sa partie inférieure de vis à oeillet 31 qui sont portées par le même axe vertical que celles disposées dans la partie supérieure du contrepoids afin de guider parfaitement, et sur toute la hauteur dudit contrepoids, les câbles 16 et 17.Also, the structure of the counterweight 11 is integral in its lower part of eyelet screws 31 which are carried by the same vertical axis as those arranged in the upper part of the counterweight in order to guide perfectly, and on any the height of said counterweight, cables 16 and 17.

    En effet, chaque vis à oeillet 31 est traversée par les câbles de guidage 16 et 17 qui sont tendus entres les points extrêmes supérieurs et inférieurs pour guider dans toutes les directions le contrepoids 11 lors de ses déplacements verticaux à l'intérieur du montant 3.In fact, each eyelet screw 31 is crossed by the guide cables 16 and 17 which are stretched between the upper and lower end points to guide in all directions the counterweight 11 during its vertical displacements at inside the upright 3.

    Les vis à oeillet 31 reçoivent un traitement intérieur pour pouvoir résister lors des déplacements du contrepoids 11 au frottement contre les câbles de guidage 16 et 17.The eyelet screws 31 receive an internal treatment to be able to resist during displacements of the counterweight 11 with friction against the guide cables 16 and 17.

    On comprend aisément de la description ci-dessus que le contrepoids 11 travaille en sens inverse par rapport au rideau souple, c'est à dire que le rideau est en position de fermeture lorsque le contrepoids est en position haute, et inversement.It is easily understood from the above description that the counterweight 11 works in the opposite direction to the flexible curtain, i.e. the curtain is in closed position when the counterweight is in the high position, and vice versa.

    Ainsi, lorsque le motoréducteur n'est plus alimenté en électricité, il est nécessaire de débloquer le frein permettant au rideau souple de remonter d'une position de fermeture à une position d'ouverture du fait de la différence de masse entre le contrepoids 11 et celle du rideau souple.When the gear motor is no longer supplied with electricity, it is necessary release the brake allowing the flexible curtain to rise from a position closing in an open position due to the mass difference between the counterweight 11 and that of the flexible curtain.

    En outre, le contrepoids 11 joue un rôle de sécurité lorsque le motoréducteur vient à casser pour empêcher la chute du rideau souple.In addition, the counterweight 11 plays a safety role when the gearmotor comes break to prevent the fall of the flexible curtain.

    En effet, la masse du contrepoids 11 étant légèrement supérieure à celle du rideau souple, ce dernier est automatiquement remonté en position d'ouverture.Indeed, the mass of the counterweight 11 being slightly greater than that of the flexible curtain, the latter is automatically raised to the open position.
