A hoistway door seal structure for limiting the flow of fluid into or out of a hoistway to restrict the passage of smoke and water into or out of the hoistway in the event of a fire, comprising:
- a wall structure having an opening therein defining a hoistway entrance having a headwall, a pair of lateral jambs and a sill;
- a pair of opposing hoistway doors sized to substantially cover the hoistway entrance when in a fully closed position and to allow access to the hoistway through the hoistway entrance when in a fully open position, each of the hoistway doors having a lateral portion, a meeting edge, a top portion, and a bottom portion;
- a door support rail positioned in a generally horizontal orientation and connected to the wall structure, the door support rail having a roller support surface;
- at least one door support truck connected to each door, each door support truck having a support roller engaging the roller support surface of the support rail to support a respective one of the opposing hoistway doors while permitting substantially planar movement of the respective one of the hoistway doors in a substantially lateral direction between the fully open position and the fully closed position, wherein when in the fully closed position the hoistway doors are spaced from the sill to define sill spaces, spaced from the headwall to define transverse spaces, and spaced from the lateral jambs to define lateral spaces, and the meeting edges of the hoistway doors are spaced from each other to define a meeting edge space;
- an elongated lateral extension extending from a lateral portion of each hoistway door toward the wall structure;
- lateral seals extending from the wall structure toward the hoistway doors in an overlapping relationship with a respective one of the lateral extensions extending from the hoistway doors to sealably engage the respective one of the lateral extensions to seal the lateral spaces when the hoistway doors are in the fully closed position;
- an elongated seal connected to the meeting edge of one of the hoistway doors, the elongated seal being sized to sealably engage the meeting edge of the other doors when the hoistway doors are in the fully closed position to seal the meeting edge space;
- elongated transverse extensions extending from the top portion of each hoistway door toward the wall structure, each of the transverse extensions having first and second ends and a sealing surface extending therebetween, the first end being spaced a first distance from the headwall and the second end being spaced a second distance from the headwall that is different than the first distance so the sealing surface is at an angle relative to the headwall;
- elongated transverse mating structure extending from the headwall toward the transverse extensions, each of the transverse mating structures having a seal mating surface substantially parallel to the sealing surface of a respective transverse extension;
- and
- an elongated seal connected to the one of the seal mating surface and the sealing surface, the roller support surface of the door support rail having guide portions to guide the hoistway doors to move along a path of movement in a selected direction relative to the transverse mating structures between a partially closed position and the fully closed position as the hoistway doors are moved into and out of the fully closed position, the seal being in sealable engagement with the sealing surface of the transverse extension and the seal mating surface of the transverse mating structure to seal the transverse spaces when the hoistway doors are moved into the fully closed position, and the sealing surface of the transverse extensions being spaced apart from the seal mating surface of the transverse mating structure with the seal being out of engagement with the other one of the seal mating surface and the sealing surface when the hoistway doors are moved into the partially closed position.
