Definitions

  • the present invention relates to an emergency curtain, in particularly a fire curtain.
  • fire curtain is used to indicate any curtain intended to contain or at least retard not only fire as such but any effect or combustion product of fire, such as smoke.
  • Fire curtains are installed in premises, such as shops, for dividing the interior of the premises in the event of a fire to slow the spread of smoke and the fire.
  • they are installed in ceilings and are deployed by unrolling down from an opening in the ceiling (see for instance document GB-A-2108839).
  • the opening is an elongate gap or slot in the ceiling.
  • the latter may be a conventional ceiling attached to joists or a suspended ceiling lower than the joists or other structural members, the opening being between boards, panels or like member comprising the ceiling. Closing the opening in the ceiling can be aesthetically difficult.
  • the object of the invention is to provide a curtain having an improved ceiling aperture closure of a ceiling opening.
  • An emergency curtain of the invention for installation at a ceiling opening comprises:
  • the outer member is conveniently of a section and material to be flexible for following ceiling undulations.
  • the outer member should engage the ceiling internally of the opening, with the member fitting within the opening; preferably, the outer member is wider than the opening and engages the underside of the ceiling.
  • the resilient means comprises a series of spring connections between the inner and outer members.
  • the springs are arranged longitudinally of the outer member with flexible connections turning their line of action upwards the to inner member.
  • the curtain 1 shown in the drawings comprises a conventional pair of curtain rolls 2,3 - for a double skin curtain - mounted in a housing 4 suspending from a ceiling structural member 5 above an opening 6 in the ceiling 7.
  • a winding mechanism (not shown) is arranged at one end of the housing for driving and stopping the rolls to raise or lower the curtain fabric 8 rolled on the rolls as required.
  • a bottom bar 9 is attached to the bottom edge of the curtain fabric.
  • the bottom bar has an inner member 11 formed of two identical members 12,13 fastened by screws 14 back-to-back with the fabric 8 clamped between.
  • the inner member is of a width to drop through the opening 6. Beneath the inner member, a wider outer member 15 is arranged. It is wider than the opening, so that when drawn against the ceiling, it obscures the edges of the ceiling at the opening.
  • the outer member is connected to the inner member by wires 16 and springs 17.
  • the inner member has upwardly divergent lower sides 18.
  • the outer member is essentially flat, with low flanges 19 extending up from its top surface.
  • the flanges have upwardly divergent lips 20, which engage the lower sides 18 for centring of the inner and outer members when they are in contact as shown in Figure 2.
  • the members are held slightly apart by plastics material eyelets 21 pressed into horizontal portions of the flanges 19.
  • the wires 16 pass through apertures 22 in the inner member above the eyelets and terminate above them. Below the eyelets, or at least each pair of them, the wires turn in pairs towards each other and are fixed to opposite ends of the springs 17. Thus tension in the springs urges the outer member up towards the inner member.
  • the wires and spring tension are sized to be able to lift the outer member. They are of stainless steel, the wires being nylon covered.
  • the outer member has little vertical height, whereby even when extruded in aluminium it is flexible for vertical deflection.
  • the outer member can flex to accommodate undulations in the ceiling level.
  • the springs are strong enough in their extended, use state to flex the outer member. This is the normal use position.
  • the inner member of the bottom bar drops through the opening in the ceiling and the springs draw the outer member up against the inner member.
