Definitions

  • 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.
  • 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.
  • 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.
  • the door includes means for releasing the engine brake in the event of a power failure.
  • 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.
  • 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.
  • the motor When 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.
  • the engine brake In the event of a power failure throughout the installation, the engine brake is released and the winding shaft can rotate freely
  • 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.
  • 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.
  • 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.
  • 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.
