Definitions

  • the present invention relates to a balancing device for a lifting curtain door: factory doors, warehouses, garages, shops etc., comprising a shaft controlling the winding of a curtain or straps lifting a curtain, said shaft carrying two drums for winding suspension belts of two counterweights, the curtain being intended mainly to clear or close a bay provided most often for the passage of vehicles: cars, trucks, handling trucks, etc.
  • the curtain when the curtain is rolled up on a tree at the upper part, the rolled part no longer exerts any gravity force, only the hanging part is to be lifted for winding;
  • the curtain can be made up of panels which slide between slides, which are folded horizontally, or almost, above the door, the panels arranged on a horizontal sliding path no longer exert any gravity force; there are doors made up of panels which, when being raised, come to be stored above the door in a position where they no longer exert gravity; etc.
  • the invention also applies to sectional doors, the elements of which tilt in a horizontal position, provided that the door lifting mechanism is in kinematic connection with the winding shaft of the counterweight belts.
  • a counterweight device has been proposed in several masses, which in the descent, stop at different levels (see American patent US-1,750,042 and Soviet patent SU-661,098).
  • This device is effective, but is not suitable for all applications.
  • a balancing device for a lifting curtain door comprises two counterweights, one of which is suspended by a belt of length less than the stroke of the counterweight corresponding to the complete movement of the curtain (winding or unwinding) , the belt can be wound in both directions, so that after a certain downward travel, when the curtain continues to rise, the counterweight belt is wound in the other direction, and said counterweight rises, exerting a resistant force instead of a motor force.
  • the action of the counterweights then results from the difference in masses and no longer from the sum.
  • FIG. 1A shows the elements concerned by the present invention of a liftable curtain door comprising a curtain 1 which can be rolled up and unwound on a shaft 2, possibly fitted with a drum 2A to be raised or lowered.
  • the length of the shaft 2 is greater than the width of the curtain and two drums 3, 4 are arranged, for example on each side of the curtain, on the winding shaft.
  • Two counterweights 5, 6 are suspended from belts 7, 8 which can be wound on the drums.
  • the counterweights move in appropriate corridors 9, 10, shown partially.
  • the door generally comprises other elements, not shown, such as an upper crosspiece sheltering the shaft 2, as well as an electric motor, a transmission, a limit switch, and vertical lateral uprights comprising slides for the edges of the curtain. This can be reinforced by horizontal reinforcing bars placed at different levels, which are placed in the winding of the curtain on the shaft 2. There can also be a load bar on the lower edge of the curtain.
  • the counterweight 6 is arranged in a conventional manner. It is up when the curtain is lowered (unrolled); it descends when the curtain rises, and is down when the curtain is raised ( Figure 3A).
  • the stroke of the counterweight 6 can be the same as that of the curtain, or different, depending on the choice of the diameters of the winding shaft of the curtain and the drum diameter 4.
  • the mass of the counterweight is chosen accordingly. This mass will be designated hereinafter long mass (long counterweight) and the belt which suspends it long belt.
  • the counterweight 5 is mounted in accordance with the present invention.
  • the belt 7 has a length less than the stroke of the counterweight corresponding to the full stroke of the curtain 1, and the belt is mounted on the drum 3 so that it can be wound in both directions (see in particular Figures 1B, 2B and 3B).
  • This counterweight will be designated hereinafter short counterweight, and its mass mass short while the belt by which it is suspended will be designated short belt.
  • the drum may include grooves to promote regular winding of the cable. In the case of the belt, it winds on itself, and the winding diameter increases while the counterweight rises. It therefore exerts a higher initial effort, which is favorable when it is necessary to start rolling up the curtain whose total weight is to be lifted.
  • the counterweights can be equal or different. In general, the counterweight 6 will be heavier.
  • the device operates as follows:
  • This difference is chosen for example to compensate for the residual weight of the curtain, which will thus continue to rise until complete winding.
  • the curtain will stop in this position, and all the more so if the counterweight 5 is heavier than the counterweight 6.
  • the curtain can be reassembled without a motor (in the event of a breakdown for example) at least up to a certain height, and completely if desired, by choosing the value M6 - M5.
  • the short counterweight When the short belt is fully unwound, the short counterweight reaches a low position, below which it cannot descend.
  • This low position corresponds to an intermediate height from the bottom of the curtain.
  • This height can be chosen as desired depending on the length of the short belt.
  • This intermediate height can be situated towards the middle of the total height of the opening of the curtain, so as to adapt the force of the counterweights to the unrolled mass of the curtain.
  • This intermediate height can be located in the upper part, to adapt the differential force of the counterweights to a damping of the curtain at the end of the lifting stroke.
