Definitions

  • the present invention relates to a safety and emergency actuation device for an accordion door.
  • Such doors essentially comprise, depending on whether they are doors with hinged horizontal panels or with flexible curtain stiffened at regular intervals by horizontal reinforcing bars, lifting straps fixed to the base of the lower panel or to the lower bar and preferably passing in guides fixed on the articulation of certain panels or on some of the other bars and a shaft winding of the straps overhanging the assembly, driven by an electric motor and blocked by braking means when said motor is not in operation.
  • Patent US-A-3,739,832 describes an emergency system for a flexible closing grid of the upper winding type: when the motor lowers the grid in the closed position, it causes the tension of a spring, which, in in case of engine failure, can raise the grid to a certain height allowing passage.
  • the present invention relates to a safety and emergency actuation device for an accordion door making it possible, as the case may be, to prevent the curtain from falling completely or to cause it to rise partially and quickly.
  • the subject of the present invention is a safety and emergency actuation device for an accordion door, in particular of the type of those which include in particular a flexible curtain guided by two uprights, horizontal reinforcing bars arranged at regular intervals, lifting straps fixed to the lower bar and capable of passing through guides fixed to certain other bars, a blood winding shaft overhanging the assembly driven by an electric motor and blocked by braking means when said motor does not is not in operation, characterized in that it comprises at least one mass counterweight making it possible to partially raise the curtain to a height allowing passage.
  • the counterweight (s) is (are) calculated to cooperate with the electric motor driving the winding shaft of the straps during the opening and closing of the accordion door .
  • the lifting provided by the counterweight (s) is controlled, depending on whether the braking means of the strap winding shaft are constituted by the brake of a brake motor or by a latching device located on the lower bar, by manual means for releasing said brake or for disengaging said latch.
  • the counterweight (s) circulate (s) freely in a casing attached to one of the door jambs, either in the plane of the door, or projecting towards the inside or out.
  • FIG. 1 an accordion door of the type which includes a flexible curtain which is recognized in particular the flexible curtain 1, the horizontal reinforcing bars 2, the lifting straps 3 fixed to the lower bar and passing in guides 4 fixed on certain bars, the uprights 5 U-shaped in which the ends of certain bars slide, the beam 6 forming a lintel and on which the brake motor 7 which is subjected drives the shaft 8 for winding the angles and the bearings 9 which support said tree.
  • the rotational force exerted by the counterweight 12 on the shaft 8 via the drum 10 depends both on the mass of the counterweight 12 and on the diameter of the drum 10. This force is calculated so that, under its sole action, the motor 7 not operating and the braking means being released, the door opens on a determined fraction of its height.
  • the counterweight 12 then occupies an intermediate position between the high position it occupies when the door is fully closed ( Figure 1a) and the low position it occupies when the door is fully open ( Figure 1b).
  • This force being calculated, the mass of the counterweight 12 and the diameter of the drum 10 are determined, taking account in particular of their size of the stroke of the counterweight between its high position and its low position, mechanical stresses exerted on the tree etc.
  • it may be necessary to envisage a device comprising 2 counterweights placed respectively at each end of the winding shaft 8 of the angles and allowing a balanced distribution of the forces.
  • the rotational force exerted on the shaft 8 by the counterweight occurs in three circumstances: when the winding shaft of the straps becomes detached from the brake motor, the door being open or being opened; when the brake motor is out of service, the door being closed; during ordinary operation of the brake motor.
  • the curtain ballasted with rebar, has tendency to fall due to their own weight. This is where the counterweight plays an essential role for safety, quite specific to this type of door. If, when the tree breaks (or any other equivalent accident), the base of the curtain has reached a height greater than the fraction of total door opening height defined above - corresponding to the balancing of part of the weight of the curtain by the counterweight - the curtain then lowers with decreasing speed until it reaches this predetermined height. If, on the contrary, the curtain has not reached this height, it rises with decreasing speed until it reaches it.
  • the counterweight prevents the curtain from falling completely and eliminates the risk of accident that could result, especially for people.
  • the brake motor 13 and the brake 14 of the brake motor are supplied at the same time.
  • the switch 15 When the switch 15 is closed (FIG. 2 a), the motor 13 operates and the brake 14, which may notably include an electromagnet 16 and a compression spring 17, is released, the force generated by the electromagnet 16 being higher and opposite to that of the compression spring 17.
  • the switch 15 When the switch 15 is open (FIG. 2 b) the motor 13 does not work and the brake 14 blocks the shaft by the effect of the force of the compression spring 17.
  • the situation of the brake motor is identical to the previous one.
  • the compression spring of the brake is compressed by means of a manual control 21 .
  • the motor 13 does not work and the electromagnet 16 under tension generates a force greater and opposite to that of the return spring 18 which applies the brake.
  • the brake is released and the door would automatically raise if blocking means were not provided.
  • this operating mode of the brake motor there is therefore, for example, a latch on the lower bar of the door which engages in a corresponding fixed device when said bar is at ground level.
  • the rotational force generated by the counterweight 12 and the drum 10 does not act only in the particular situations mentioned above, that is to say when the winding shaft of the straps disconnects from the brake motor or that the brake motor is out of service, but also cooperates with the motor in normal operation.
  • the counterweight assists in lifting the curtain and the motor only works as soon as the weight of the raised part of the curtain balances the counterweight.
  • the motor only works from the moment when the counterweight balances the weight of the lowered curtain part, it must hoist said counterweight to its high position.
  • the use of a counterweight of the type which has been described above therefore makes it possible to use a motor less powerful than that which has been used in installations which do not have one.
  • Another U-shaped door jamb 5 consisting of a U-shaped metal profile whose parallel parts serve as a guide for the flexible curtain 1, another U-shaped profile 23 is added, possibly by welding, which will have been dimensioned so as to delimit a rectangular parallelepiped in which the counterweight 12 can circulate freely.
  • the counterweight casing is a parallelepiped, three faces of which are formed by the U-shaped profile 23 and the fourth by the part of the upright 5 which is perpendicular to the plane of the door. This casing is therefore located in the extension of the door which it widens accordingly.
  • the counterweight casing is a parallelepiped, three faces of which are formed by the U-shaped section 23 and the fourth by one of the parallel parts of the upright 5. This casing is therefore not in the plane of the door, but protrudes inward or outward.
  • a pulley 22 is provided fixed at the plumb of the casing to ensure the return of the belt 11.
