Definitions

  • the present invention relates to a seal for mounting to a door frame, and relates particularly, but not exclusively, to a smoke and fire seal which also provides a barrier against noise.
  • Door seals such as acoustic seals, fire seals or weather seals are typically attached to a door frame by mounting the seal into a recess in the door frame and are engaged by a door mounted to the frame when the door is in a closed position.
  • a combined fire and smoke seal 2 has an elongate body 4 extruded from intumescent material, which provides a large amount of expansion when it intumesces and which is angled to form two arms. Each arm has a terminal edge face to which a resilient seal lip 6, 8 is integrally connected to define a pair of smoke seals.
  • a door 10 mounted to a door frame 12 to which the seal 2 is mounted is in the closed position, the door 10 engages the pair of lip seals 6, 8 to provide a smoke seal.
  • the intumescent material expands to fill the gap between the door 10 and the door frame 12.
  • Preferred embodiments of the present invention seek to overcome one or more of the above disadvantages of the prior art.
  • a seal for mounting to a door frame comprising:
  • first resilient seal member and at least one second resilient seal member extending from a first surface of the support member and at least one member of intumescent material mounted in a fixed position relative to said first seal member and the or each said second seal member, this provides the advantage of providing a combined smoke and fire, and possibly also acoustic, seal which can be installed in a single recess in a door frame, without the necessity of removing the door from the door frame.
  • At least one said member of intumescent material may be mounted to said support member.
  • At least one said member of intumescent material may form at least part of said support member.
  • the intumescent material may include graphite and PVC.
  • the first seal member may extend in an undeformed state at an angle greater than 90° to said first surface of said support member.
  • the angle may be between 95° and 100°.
  • the first seal member may have tapered cross section in a direction extending away from said support member.
  • At least one said second seal member may extend from said first surface of said support member towards said first seal member.
  • At least one said second seal member may extend substantially perpendicularly to said first surface of said support member.
  • the seal may be provided with adhesive material on a second surface of said support member, opposite to said first surface.
  • the first seal member and/or at least one said second seal member may include PVC and/or acrylonitrile butadiene rubber.
  • the first seal member and/or at least one said second seal member may have a deflection recovery value of at least 40%.
  • the support member may be formed from PVC.
  • At least one said second seal member may extend from said first surface of said support member at an angle between 10° and 60°.
  • a door assembly comprising a door frame, a door adapted to be mounted to the door frame, and a seal as defined above.
  • a method of manufacturing a seal for mounting to a door frame comprising co-extruding:
  • a fire and smoke seal 102 embodying the present invention comprises an elongate base member 104 of substantially rigid PVC material which is coextruded with a first seal member 106, a pair of second seal members 108, 110, the first and second seal members being formed from a PVC/acrylonitrile butadiene rubber compound, and an elongate strip 112 of intumescent material, such as graphite in a PVC matrix, and which is adapted to expand when it comes into contact with fire.
  • the intumescent material 112 is securely bonded to the base member 104 which has the advantage of minimising the tendency of the intumescent material 112 to become detached from the base member 104 as it expands.
  • the first seal member 106 extends from an edge of a first surface 114 of the base member 104 at an angle of more than 90°, typically 95° to 100°, such that the seal 102 can be mounted to a first surface 116 ( Figure 5 ) of a door frame 118 and the first seal member 106 resiliently engage a second surface 120 of the door frame 118 perpendicular to the first surface 116. This enables the first surface 116 to be maintained in a deformed state in contact with the second surface 120 of the door frame 118, without the necessity of fixing the seal 102 to the second surface 120 of the door frame 118, as shown in Figures 5 and 6 .
  • the second seal members 108, 110 each extend from the first surface 114 of the support member 104 at an angle of approximately 40°, and are adapted to be engaged by a door 122 in its closed position such that the second seal members 108, 110 are not fully compressed against the first surface 114 of the support member 104.
  • air, acoustic and smoke seals are formed by the second seal members 108, 110 extending between the door 122 and the first surface 116 of the door frame 118.
  • the seal 102 of the present invention is mounted to a single recess 124 in the door frame 118.
  • the advantage is provided that it is not necessary to provide two recesses in the door frame to accommodate an acoustic seal and a smoke/fire seal.
  • the fire retardant performance of the seal 102 of the present invention has been found to be surprisingly better than that of known fire seals.
