ABSTRACT:
A hoistway door seal structure for limiting the flow of air through a hoistway opening when the door is closed. The hoistway door seal structure includes a hoistway door that covers a hoistway entrance defined by an opening in a hoistway wall structure. An elongated door support member is connected to the wall structure and is positioned in a generally horizontal orientation above the hoistway entrance. A seal structure is supported between the hoistway door and the wall structure. A door support is connected to the hoistway door and is movably connected to the elongated support member to support the door while permitting movement of the door in a lateral direction between an open position permitting access to the hoistway and a closed position wherein the door substantially covers the hoistway entrance with a space between the hoistway door and the wall structure. The elongated support member includes a guide portion that guides the hoistway door, as the hoistway door is moved to the closed position, in a second direction toward the seal structure. The second direction being different than the lateral direction such that the hoistway door sealably engages the seal structure to seal the space between the door and the wall structure when the door is closed.
