Definitions

  • the present invention relates to an improvement to sliding doors provided with an automatic closing control device; it relates in particular to an improvement to sliding fire doors, of the type with automatic closing by gravity.
  • sliding fire doors are closed automatically by gravity, under the action of their own weight, on an inclined rail, or on a horizontal rail using a counterweight.
  • This closing can be controlled by a fuse which must blow around 70 ° C and / or by an electromagnetic lock controlled by a fire detection system.
  • These doors are implemented during real alarms, in the event of a fire for example or during periodic simulation exercises, so as to overcome any problems that would prevent the proper functioning of the system in the event of a real alarm. (fouling of the rail, compaction of the rollers ).
  • the doors undergo stresses and damage which can alter their capacities.
  • the closing speed of the opening which depends on the one hand on its weight characteristics and on the other hand on the inclination of the rail or the mass of the counterweight, induces violent shocks in contact with the frame. These shocks quickly cause significant damage, both on the frame itself and on the corresponding edge of the opening.
  • This closing speed also causes several rebounds on the frame, capable of stabilizing the sliding door in the ajar position; this problem is accentuated if the frames and / or opening are distorted by repeated shocks.
  • the document BE-825 407 proposes to equip the door with braking and damping means for the opening which act during closing, at the end of the stroke.
  • These means are made up a hydraulic or pneumatic braking cylinder, the projecting piston rod of which cooperates with a stop secured to one of the tie rods of the leaf and secured to the upper part of said leaf by means of anchoring screws.
  • the invention aims to overcome this drawback by providing accessories, and in particular a contact abutment with the rod of the damping cylinder, fixed on original supports which do not modify the structure of the door and make it possible to preserve its behavior. fire.
  • the fire door according to the invention is of the type with automatic closing by gravity; it consists of a frame associated with an opening mounted on a support structure. This opening is provided with retaining means in the open position and means for releasing said retaining means during a determined event, for example a fire detection, so as to cause said opening to be automatically closed.
  • This door comprises means for braking and damping the opening, in the form of a pneumatic cylinder whose external end of the piston rod cooperates with a stop disposed on the opening for obtaining the braking and the damping during closing, at the end of the stroke.
  • the stop is adapted to the opening without modifying the structure of the latter, by means of a member in the shape of a stirrup secured by pinching by means of clamping screws.
  • the stop extends vertically from a stirrup-shaped plate, which stirrup has a notch for its attachment to the upper edge of the opening, at one of its roller support tie rods.
  • the stop consists of a metal tube of substantially rectangular section which extends vertically from the support plate.
  • the fire door comprises means for automatic resetting of the pneumatic cylinder which consist of a permanent magnet disposed on the stop.
  • the cylinder rod is provided with a reset plate intended to cooperate with the magnet; this plate is mounted floating at the end of the rod, anchored by means of a ball joint.
  • the pneumatic cylinder is a leakage cylinder controlled by an adjustable flow reducer which allows fine adjustment of the damping according to the characteristics of the door.
  • the retaining means of the opening member consist of an electromagnetic coil and the door comprises at least one position switch intended to signal the open or closed position of the door.
  • This or these switches cooperate with a contact stop of suitable shape, which stop consists of a donkey structure protruding from the upper edge of the opening.
  • the fire door comprises a set of accessories: jack, stop, contact stops and contact of electromagnetic coil, adapted without modification of the structure, by means of members in the form of stirrups, secured by pinching on the opening or its guide rail.
  • the sliding fire door with automatic closing by gravity shown in FIGS. 1 and 2, consists of a frame 1 defining a passage opening for example, associated with an opening 2.
  • This opening 2 is slidably mounted on an upper rail 3, by by means of internal rollers, not shown, mounted on tie rods 4.
  • the tie rods 4 are secured by any means on the upper edge of the leaf 2; they are associated with internal rollers to produce suspension members for the opening and allow it to slide along the guide rail.
  • the rail 3 is secured above the opening 2 and the frame 1, on the wall for example, by means of anchoring lugs 3 a ; it is inclined relative to the horizontal, in the direction of closing the opening 2 to allow the displacement of the latter, by simple gravity, in order to partition the passage opening.
  • the sliding door is of the self-closing gravity type and the opening is provided with retaining means 5 in the open position, associated with release means during a determined event and in particular in the event of fire detection.
  • the door also comprises means 6 for braking and damping the opening, which act during closing, at the end of the stroke.
  • These means 6 consist of a pneumatic cylinder 7 of the controlled leakage type, shown diagrammatically in FIG. 3.
  • the cylinder 7 consists of a body 9 inside which moves a piston 10 which divides said body 9 into two chambers 11 and 12.
  • the rod 13 of the piston 10 extends outside of the body 9, on the side of the chamber 12, in the direction of the opening 2 and more particularly on the line of a stop 14 secured to the upper edge of said opening.
  • Chamber 12 is provided with an air intake orifice 15; the compression chamber 11 has a calibrated orifice 16 which acts as a flow reducer.
  • the pneumatic cylinder 7 is provided at its ends with two normal high brackets 17 each secured to a stirrup 18 fixed on the guide rail 3.
  • the stop 14 consists of a metal tube of substantially rectangular section, which extends vertically from a plate 19 in the shape of a stirrup.
  • This stirrup is secured to the upper edge of the opening 2 and preferably at one of its tie rods 4, as can be seen in Figure 2, in order to improve the robustness of its positioning.
  • the plate 19 has for this purpose, substantially in its central part, a notch 19 ′ for the passage of said tie rod 4, which consists of a vertical rod which extends substantially from the middle of the upper edge of the leaf 2; the notch 19 ′ has a width corresponding substantially to that of the tie rod 4.
  • the plate 19 is fixed by pinching by means of clamping screws on the upper edge of the opening 2, without modifying the structure of the latter.
  • the inclination of the rail 3 allows the opening of the opening element 2 by gravity, in order to close the door.
  • the stop 14 comes into contact with the end of the rod 13 of the pneumatic cylinder, at the end of the stroke, just before the contact of the opening leaf on the frame.
  • the piston 10 moves in the cylinder body during the progressive retraction of the rod 13 and this displacement causes the reduction of the volume of the compression chamber 11.
  • the orifice 16 allows the progressive leakage of the fluid contained in the chamber 11. This progressive leak determines the damping of the opening 2; it is a function of the characteristics of the door as well as of the calibration of the orifice 16.
  • the jack 7 with controlled leakage is advantageously associated with an adjustable flow restrictor 20, mounted in line.
  • This adjustable flow reducer 20 is characterized by a needle screw, visible diagrammatically in FIG. 3, which is screwed, in an appropriate arrangement, on the orifice 16.
  • the needle screw makes it possible to refine the adjustment of the air flow according to the desired depreciation characteristics; advantageously, the braking and damping are adjusted so that the opening 2 has a reduced speed, almost zero, when it comes into contact with the frame 1 for closing the door.
  • This closed position is shown in Figure 2, on which we notice the stop 14 in contact with the end of the rod 13 of the cylinder, which is substantially fully retracted.
  • the actuator 7 is provided with automatic resetting means implemented during reopening.
  • These resetting means consist of a permanent magnet 21 bolted to the stop 14, substantially at the level of contact with the rod 13 of the pneumatic cylinder.
  • the free end of this rod 13 is provided with a floating reset plate 22, that is to say anchored by means of a ball joint, to allow a certain freedom of movement and improve contact with the permanent magnet 21; this anchor is shown schematically Figure 3.
  • the magnetic connection obtained between the rod 13 and the stop 14 when closing the opening allows the extraction of said rod 13 upon reopening. This extraction is made possible by the air leakage through the orifice 15 of the jack 7; it is carried out until the end of the race and beyond the magnet is released.
  • the sliding door with automatic closing by gravity is provided with means 5 for retaining in the open position.
  • These means consist of an electromagnetic coil 23 anchored on a support 24 fixed to the wall for example, near a tab 25 forming a stop for the rear end of the opening 2.
  • the electromagnetic coil 23 cooperates with a contact 26 in the form stirrup fixed on the edge of the opening 2 to retain said opening when it is electrically powered.
  • the electrical supply to said coil 23 is controlled by conventional fire detection means, not shown, which allow the electrical supply to be cut off to cause the release of the retaining means and the automatic closing by gravity of the opening. .
  • the sliding door according to the invention is also provided with means for detecting its position.
  • These means consist of position detectors 27 and 28 in the form of roller contactors disposed respectively at each end of the rail 3; they are fixed on positioning brackets associated with plywoods arranged in the rail 3. This particular assembly makes it possible not to modify the structure of the rail; it is made in such a way that the switches do not hinder the progression of the opening or of its guide rollers.
  • the contactors 27 and 28 are intended to cooperate respectively with contact stops 29 and 30 of suitable shape, arranged at each end of the leaf 2, in the upper part.
  • These stops 29, 30 consist of a donkey structure 31 projecting projecting, laterally, on a stirrup or rider 32 positioned on the upper edge of the opening 2.
  • the door In the normal position, the door is open. It is kept in this position thanks to the electromagnetic coil 23 supplied by means of a signaling board, not shown, for example for fire detection. Switch 27 signals that the door is open; this information is transmitted to display means located nearby.
  • the electromagnetic coil 23 is acted upon and the leaf 2 is released.
  • the latter descends by its own weight until the stop 14 meets the piston of the jack 7; it is gradually braked during the stroke of said cylinder, to stop gently on the frame 1, without causing a jerk.
  • the position switch 28 is then pressed and signals that the door is in the closed position.
  • the reopening of the opening is carried out manually, by traction.
  • This reopening allows automatic resetting of the jack 7 by means of the permanent magnet 21 fixed on the stop 14. This magnet extracts the piston until the end of the stroke and then becomes free.
  • the opening is returned to its normal opening position, in abutment on the bracket 25; the coil 23, automatically reset, allows it to be retained in the open position.
  • FIG. 4 shows, in thin dashed lines, a donkey structure 31 mounted on the stirrup 32 which constitutes one of the stops 29, 30. This type of connection makes it easier to assemble the various accessories and allows easy positioning adjustment. It also makes it possible to make no modification to the door itself and in particular to avoid drilling, so as to preserve its resistance to fire.
  • the respective position of the actuator 7 and stop 14 can be reversed, the actuator then being on the opening and the stop on the guide rail. It is also possible to envisage having a fixed actuator acting directly on the edge of the opening, for example.
