  • Figure 3 shows a side-on view of part of the fire and smoke barrier apparatus of Figures 1 and 2.
  • FIG. 1 shows an exploded view of an example of a fire and smoke barrier apparatus according to a first embodiment of the present invention.
  • the fire and smoke barrier apparatus is denoted generally by reference numeral 1, and comprises a fire- resistant curtain 2 comprising a sheet of fire-resistant material such as is well-known to those skilled in the art.
  • the fire and smoke barrier apparatus 1 is attached to a wall W adjacent an aperture A, in this case defining a serving hatch.
  • the curtain 2 is attached to a roller 3 that is rotated by a motor 4 located inside roller 3
  • the roller 3 and motor 4 are located inside a head box 5.
  • the motor 4 is used to move the roller 3 to move the curtain from a deployed position in which the curtain 2 forms a fire and smoke resistant barrier across the aperture A to a retracted position.
  • a curtain weight 10 is provided at the bottom of the curtain to facilitate correct hanging and deployment of the curtain 2.
  • a brake (not shown) is released and the curtain weight 10 causes the curtain 2 to move from the retracted to the deployed position.
  • the flat-bottomed curtain weight 10 abuts ledge 13.
  • curtain edge portions 6a, 6b are located in channel guides 7a, 7b, which guide the curtain as it is deployed and/or retracted.
  • each of channel guides 7a, 7b would be provided with a smoke seal that forms a seal with the curtain to inhibit passage of smoke from one side of the curtain to the other when the curtain is deployed.
  • a smoke seal is typically in the form of an elongate brush (often known as a brush strip) that forms a seal with the curtain.
  • each of the channel guides 7a, 7b there is no need for each of the channel guides 7a, 7b to be provided with a smoke seal.
  • Each curtain edge portion 6a, 6b is provided with a pair of elongate sealing flaps 8a, 8b.
  • Each elongate sealing flap 8a, 8b is made of a fabric material and is configured to form a seal with a corresponding channel guide surface 9a, 9b when the curtain 2 is deployed.
  • the flaps 8a, 8b are attached to the respective edge portion 6a, 6b of the curtain 2 by sewing, although those skilled in that art will realise that other means for attachment are possible. Sealing flap 8a projects away from first side 2a of curtain 2 and sealing flap 8b projects away from second side 2b of curtain 2.
  • Flaps 8a, 8b are configured so that increased air pressure that results from a fire urges the respective flap 8a, 8b into an enhanced sealing engagement with the respective channel guide surface 9a, 9b. This enhanced sealing engagement provides enhanced protection against the passage of smoke.
  • BS EN 12101 defines the technical characteristics for a smoke barrier that is not fire resistant. If a barrier is to act as both a fire and smoke barrier then the barrier should conform with BS EN 8524-1 (relating to fire resistance) and BS EN 1634-3 (relating to smoke resistance for fire curtains).
  • Figures 1, 2 and 3 describes a curtain in which the sealing members are in sealing engagement with the respective channel guide surface under normal operating circumstances i.e. in the absence of a positive air pressure to urge the sealing member into sealing engagement with the respective channel guide surface.
  • the sealing member may, under normal operating circumstances, not be in sealing contact with the respective channel guide surface, but may be urged into contact with the respective guide channel surface when there is a sufficient positive air pressure, such as occurs in the event of a fire.
  • FIG. 1 The example of Figures 1, 2 and 3 describes a curtain that is deployed from, and retrieved onto, a drum. Those skilled in the art will realise that other arrangements may be used. For example, the curtain may be deployed from, and retrieved into, a folded arrangement.
  • the example describes the use of a flap to form a seal that inhibits passage therepast of smoke.
  • sealing members may be used.
  • a deformable strip may be used between the curtain and the sealing surface, the deformable strip being in a deformed (and therefore sealing) state when the respective curtain edge portion is located in the respective channel guide.
  • the flap may be advantageous because the engagement force between the flap and the channel guide surface is relatively low, thereby providing little resistance to movement of the curtain.
  • the example described above is a fire and smoke barrier apparatus.
  • the barrier may be a smoke barrier.
  • a smoke barrier would typically conform to regulations pertaining to the passage of smoke therepast, but would not necessarily conform to regulations pertaining to the inhibition of heat or fire therepast.
  • a fire barrier would typically conform to such regulations.
