Definitions

  • the invention relates to a flexible curtain door with a stack, of the type comprising substantially vertical uprights, a substantially horizontal crosspiece between the uprights, a brake motor connected to energy supply means, a counterweight, and a closing device.
  • a flexible curtain door with a stack, of the type comprising substantially vertical uprights, a substantially horizontal crosspiece between the uprights, a brake motor connected to energy supply means, a counterweight, and a closing device.
  • the flexible curtain mechanically connected to the brake motor and to the counterweight so that the force exerted by the counterweight on the movable closure device applies against the force due to the mass of the latter acting down in the closing direction.
  • the lifting being carried out by means of the brake motor, it is necessary to provide an emergency lifting device operating in the event of a power supply failure of this brake motor. It is possible to conceive either of an auxiliary power source, or of a back-up motor allowing the lifting from such an auxiliary source, or a possibility of manual lifting, for example by means of a brake release device and a crank. Such devices do not allow rapid lifting of the curtain, which is annoying and can even be dangerous if the failure is caused by an external event such as a fire for example.
  • known doors are expensive, difficult to manufacture, to transport, and to assemble, because of their weight and their large dimensions; in the event of significant deterioration, they are difficult to repair, at least on site, and require a long partial disassembly; in addition, the electro-mechanical brake-motor control device is also complex and difficult to repair.
  • the object of the invention is to remedy these drawbacks, and for this purpose relates to a flexible curtain door with a stack, of the type comprising substantially vertical uprights, a substantially horizontal crosspiece between the uprights, a brakemotor connected to supply means. in energy, a manual brake release device to release it in the event of a power failure, a counterweight, and a flexible curtain closing device movable between a fully open position and a fully closed position, mechanically connected to the motor and counterweight, so that the force exerted by the counterweight on the movable closure device is applied against the force due to the mass of the latter and acting downward in the direction of the closing, door characterized in that said force exerted by the counterweight is greater than that due to the mass of the mobile closing device from its fully closed position ju s to its fully open position, so that in the event of failure of the energy supply means, the mobile closing device is driven to its fully open position.
  • the opening speed is at least as fast as in the case of a motorized opening, and faster than by means of a crank.
  • a mobile closing device comprising a flexible curtain 4 in the form of a tarpaulin provided with substantially horizontal stiffening tubes, its suspension straps 5 here made of nylon, passanged guide stirrups 6 carried by the curtain to guide the straps by relative to it in the region of the folds thereof, and of strap clamps 18 allowing the attachment of the straps to the base of the curtain, is suspended from a drive shaft 7 by means of drums 8 strap winders to which these are fixed; alternatively (not shown in the drawings), in the case of medium and small dimensions doors used in particular for the passage of pedestrians, which have only two straps, the latter can be arranged at ends of the curtains themselves housed in the uprights, provided of course that they are open in their respective opposite faces to give access to these ends in a housing deep enough to contain the strap
  • the drive shaft 7 is mechanically linked on the one hand to a geared motor-brake 9 fixed at the top of the left upright (or, as a variant, to one end of the cross-member 3), and on the other hand to a counterweight 10 , of constant mass and exerting a constant tensile force, by means of a connecting device 11 with pulley 111 and belt 112, the pulley 111 being fixed on the drive shaft 7, and the belt on the one hand at counterweight 10 and on the other hand to the pulley 111 so as to be able to wrap around it during the ascent of the counterweight; the drive shaft 7 is fixed to the upper part of the door, for example to the cross member, by means of self-aligning bearings 12.
  • the movement of the counterweight 10, housed in the upright 2, is secured by a device for guide 13 of which, in a first embodiment, the verticality is adjustable by means of an adjustment device 14, the guide device 13 then being carried to the ground at its base by a fixing sole 15; in a second embodiment, in which the counterweight is guided by the internal walls of the upright 2, the verticality of its movement is ensured by that of the upright.
  • the rotor of the brake gearmotor 9 is secured to a manual release device 16 accessible from one of the uprights, and the gearmotor is electrically connected to an energy source, here an electrical source, and controlled by means of a device electric control 17.
  • the manual release device can be a device comprising for example a chain, a cable, or even a rod, hooked to the drum and actuated by a handle possibly via a pinion, a pulley or a linkage of reference.
  • the counterweight 10 works in reverse with respect to the curtain, that is to say that the curtain is in the low position when the counterweight is in the high position, and vice versa; thus, when the brake is released, the curtain rises from a closed position to an open position, which can be total, the mass of the counterweight being slightly greater than that of the closing device (curtain 4, straps 5 and stirrups pass - straps 6 and strap clips 18); it follows that if the brake is applied following a failure of the electrical power supply when the curtain is in the fully closed position, the curtain can be automatically raised to its fully open position simply by actuating the device manual release 16.
  • FIG. 3 shows a first possible embodiment of this guide device 13, here inside, of the adjustment device 14, and of the counterweight 10.
  • the guide device 13 comprises a tubular guide 130 resting on the sole 15 and fixed to the latter by means of a centering pin 131 fitted in its lower part, comprising a central centering stud welded in a hole in the sole, and secured to the tubular guide by means of a pin, for example a longitudinally split tubular pin 132 known in the art under the name of MECA-NINDUS pin.
  • the adjusting device 14 is constituted by a square 141 with an L-shaped section, one wing of which is fixed by two screws to the right upright 2, and a collar 142 comprising a body threaded around the tubular guide 130 and a fixing base welded to the body and fixed by bolting to the other wing of the bracket 141, at least one of these members, for example this other wing of the bracket 141, comprising an oblong hole allowing the verticality of the guide tube to be adjusted; a screw inserted in a nut welded to the body of the collar allows the tube to be blocked in this part.
  • the counterweight 10 metallic, is either in one piece pierced with a central bore for the tubular guide 130, or consists of two tubular parts 101, 102 fixed one inside the other, the internal part 101, bored, being itself threaded around the tubular guide 130, with a fairly large clearance in both cases; a hoop 103 is fixed to the upper part of the counterweight, for hanging the connecting strap (or chain, or even the cable) 112; the counterweight is guided around the guide 130 by at least one and in this case two nylon rings 104 disposed respectively at the top and at the bottom of the counterweight 10; these two rings comprise a body inserted in a respective housing produced here in the inner part 101, the two housings opening into the free ends of this inner part, and a fixing flange to this inner part; fixing the flanges to the counterweight is ensured by screws, which allows the replacement of the guide rings 104 when they are worn.
  • FIG. 4 shows a second possible embodiment of the guide device 13 and the counterweight 10.
  • a guide 130 is formed by the internal walls of the right upright 2 or of a compartment extending vertically in this upright and delimited by one or more internal vertical partitions, the counterweight 10 being housed inside the upright 2 or this compartment; the counterweight 10 then consists of superimposed steel blocks 105 whose horizontal section is slightly less than that of the guide 130, and two anti-friction plates 106 made of a material with a low coefficient of friction such as that known commercially under the name of NOFRIX arranged respectively on each side of the superimposed steel blocks, the assembly being assembled by bolting, and the two anti-friction plates having a shape similar to that of the interior section of the upright or of the longitudinal compartment and being adjusted in this guide 130; as in the case of the first embodiment, a hoop 103 is fixed to the upper part of the counterweight to hang the connecting belt 112.
  • the internal horizontal section of the guide being rectangular
  • the blocks 105 have also a rectangular section, and thus almost the entire section of the guide or the upright is occupied by the counterweight metal masses. Thanks to the external guidance by anti-friction plates, the effects of friction are notably limited, lubrication is unnecessary, and maintenance is simplified.
  • control device 17 can be housed in the left upright or in the cross member, provided that its dimensions are smaller than those of conventional devices.
  • control device 17 if it was conventionally electro-mechanical, would be rather bulky; it is therefore here replaced by a programmable automaton known per se, housed in an electrical cabinet whose dimensions allow its integration into an upright or the crosspiece, which improves the presentation, removes a large part of the wiring required hitherto between the device in the form of an external cabinet and the outside of the door, and allows the pre-wired doors to be delivered, the cables passing inside the uprights and the upper crosspiece, which reduces the installation time on the site and thus the installation cost (the cost of labor in the workshop being lower than on site), and reduces the risk of errors during assembly.
  • the structure described above allows the door to be produced in a modular form.
  • some of the modules comprising the mechanical and electrical parts, identical for all the doors, can be produced in advance, while others are produced on demand. Then simply assemble the modules to obtain a complete door.
  • the manufacturing time is considerably reduced, as well as the exposure time, because the assembly team only handles relatively light sub-assemblies.
  • the after-sales service is also simplified since in the event of mechanical shock or breakdown, there is only a limited number of sub-assemblies to be replaced.
  • the electrical module A, the engine module C, the counterweight module E, and the sole module G are identical modules for all doors, made in advance.
  • the upright modules B and F are produced on request by cutting a profile of standard length, and the same is true of the cross-member module D; the flexible curtain is also produced on request.
  • This modular structure therefore gives great flexibility in the manufacture and assembly of the door according to the invention.
