Definitions

  • the present invention relates to handling doors of the lifting curtain type, comprising a flexible curtain with horizontal reinforcing bars arranged at regular intervals, and a drive element comprising a winding shaft disposed above the curtain.
  • the edges of the curtain and / or the ends of the reinforcing bars can move in slides formed in, or by lateral uprights which support an upper horizontal crosspiece on which the winding shaft is mounted, and possibly an electric motor. and control members of this engine.
  • the invention is characterized in that said lower guide rod is located a small distance above the lower edge of the curtain, and the lower edge of the curtain has an additional flexible rebar to serve as ballast or safety edge.
  • the curtain is foldable in accordion when it is raised, at least some guide reinforcing bars are fixed to guide rings in which pass lifting straps which are wound on the shaft of winding, the lifting straps are fixed to said lower guide bar and said flexible additional reinforcing bar is not affected by the lifting straps.

Description

  • La présente invention concerne les portes de manutention du type à rideau relevable, comportant un rideau souple avec des barres d'armature horizontales disposées à intervalles réguliers, et un élément moteur comprenant un arbre d'enroulement disposé au-dessus du rideau. Les bords du rideau et/ou les extrémités des barres d'armature peuvent se déplacer dans des glissières formées dans, ou par des montants latéraux qui supportent une traverse horizontale supérieure sur laquelle est monté l'arbre d'enroulement, et éventuellement un moteur électrique et des organes de commande de ce moteur.
  • L'invention a pour objet une porte de manutention, comportant :
    • deux montants latéraux verticaux ayant chacun une glissière verticale,
    • un rideau souple relevable, ayant un bord inférieur,
    • des moyens pour relever le rideau, comportant un arbre d'enroulement entraîné par un moteur,
    • des barres d'armature horizontales de guidage disposées à intervalles réguliers sur le rideau pour guider et rigidifier le rideau, lesdites barres d'armature ayant chacune deux extrémités qui coulissent dans les glissières, lesdites barres d'armature de guidage comportant une barre d'armature de guidage inférieure.
  • Une telle porte est connue de FR-A-2548257.
  • L'invention est caractérisée en ce que ladite barre d'armature de guidage inférieure est située à une petite distance au dessus du bord inférieur du rideau, et le bord inférieur du rideau comporte une barre d'armature supplémentaire souple pour servir de lest ou de barre palpeuse.
  • Selon une forme de réalisation, le rideau est pliable en accordéon lorsqu'il est relevé, au moins certaines barres d'armature de guidage sont fixées à des anneaux de guidage dans lesquels passent des sangles de levage qui s'enroulent sur l'arbre d'enroulement, les sangles de levage sont fixées à ladite barre d'armature de guidage inférieure et ladite barre d'armature supplémentaire souple n'est pas concernée par les sangles de levage.
  • Avantageusement, la barre est constituée par un ressort à boudin.
  • D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description suivante, donnée à titre d'exemple non limitatif, en regard des dessins ci-joints, et qui fera bien comprendre comment l'invention peut être réalisée.
  • Sur les dessins,
    • la figure 1 est une vue en perspective d'un exemple de porte rideau à laquelle s'applique la présente invention ; et
    • la figure 2 est une vue en coupe partielle d'un rideau selon l'invention en position partiellement relevée.
  • Pour situer la présente invention, on a représenté sur la figure 1 une porte rideau d'un type classique. Un rideau 1 est renforcé par des barres d'armature horizontales 2 disposées à intervalles réguliers. Des sangles de levage 3 sont fixées à la barre inférieure 2A et passent dans des anneaux 4 fixés aux autres barres. Un élément moteur comprend un arbre 5 d'enroulement des sangles et un moteur 6, en pratique un moteur électrique, avec une transmission 7. D'autres éléments tels que fins de course, relais etc. sont classiques et pour cela non représentés. Les extrémités des barres, et éventuellement les bords du rideau, se déplacent dans des glissières 8, 9 formées dans, ou constituées par, des montants latéraux verticaux. Une traverse supérieure 10, constituée ici par deux poutrelles, réunit les parties supérieures des montants et supportent l'arbre 5 d'enroulement des sangles. Le moteur 6, 7 peut aussi être placé sur cette traverse. Fréquemment, le rideau 1 est en matière plastique souple non armée, et le poids des barres, avec leur inertie, peut provoquer la déformation et l'allongement du tissu du rideau. On a prévu pour cela des sangles de renforcement 11, dites d'équidistances, placées contre le rideau et fixées à chaque barre.
  • Lorsque l'arbre 5 enroule les sangles, la barre inférieure 2A est relevée, et en arrivant par intervalles consécutifs à chaque barre successive, elle entraîne une, puis deux, etc. toutes les barres jusqu'en haut. Le rideau 1 se replie entre les barres.
  • A la partie inférieure du rideau, on prévoit un petit pan supplémentaire avec une barre d'armature souple 2A, non concernée par les sangles. Cette barre peut être constituée par exemple par un ressort à boudin, un profilé plastique, etc. Elle peut servir de lest, de barre palpeuse, etc., tout en restant souple.
