Definitions

  • the present invention relates to a roller door arrangement comprising a flexible door leaf, wound on a winding roller which is mounted rotatably at the door opening, wherein the roller door is provided with flexible traction members associated with at least one driving device for applying a traction force on the flexible door leaf, to enable the flexible door leaf to be movable between a closed position and an open position.
  • One of the main purposes of the present invention is to provide a door arrangement provided with a flexible door leaf.
  • a roller door arrangement comprising a flexible door leaf, wound on a winding roller which is mounted rotatably at the door opening, wherein the roller door arrangement is provided with flexible traction members associated with at least one driving device for applying a traction force on the flexible door leaf, to enable the flexible door leaf to be movable between a closed position and an open position, characterised in that the lateral portions of the flexible door leaf is provided with a protruding portion adapted for being guided by a guide and holding the flexible door leaf between the guides, and that the flexible door leaf has at least one slit extending in the longitudinal direction of the flexible door leaf, provided with a reconnectable link portion, said reconnectable link portion being adapted to engage the door leaf slit and disengage when exposed to impact exceeding a thres-hold value.
  • the protruding portion in the guide is held thoroughly in place to withstand wind load.
  • the holding capacity of the guide exceeds the impact threshold value.
  • the protrusions of the lateral edges of the door leaf associated to the guides will provide support for external loading, such as wind load.
  • the flexible traction members, associated with a driving device, will provide a pulling force to the door leaf in the intended direction of movement of the door leaf during opening or closing.
  • the slit is held together by a reconnectable link portion adapted to disengage said slit when the flexible door leaf is exposed to a force exceeding a thres-hold value, such as impact from e.g. a truck.
  • a reconnectable link portion adapted to disengage said slit when the flexible door leaf is exposed to a force exceeding a thres-hold value, such as impact from e.g. a truck.
