Abstract
A scupper door system includes a frame defining a passageway. A door is mounted within the frame at a pivot and is therein rotatable about the pivot within the passageway between a closed position, blocking the passageway, and an open position wherein the passageway is open to permit passage of water therethrough. A latch mechanism is configured to retain the door in the closed position and is triggerable in response to a preset water condition at one side of the passage to release the door from the closed position and allow the door to rotate to the open position.
Claims20
A scupper door system, the system comprising:
- a scupper frame defining a passageway between an interior side and an exterior side of a parapet;
- a door mounted within the frame at a pivot, wherein the door is rotatable about the pivot within the passageway between a closed position and an open position, wherein in the closed position the passageway is blocked and in the open position the passageway is open to permit passage of water therethrough;
- a latch mechanism configured to retain the door in the closed position and triggerable by presence of a preset water condition at the interior side to release the door from the closed position and allow the door to rotate to the open position in a first direction;
- and
- wherein the scupper door system is configured to prevent the door from rotating to the open position in a second direction opposite of the first direction.
A method of draining a roof, the method comprising:
- locating a scupper frame within a parapet, wherein the scupper frame defines a passageway between an interior side and an exterior side of the parapet, and wherein a door is positioned within the passageway at a pivot and rotatable between a closed position and an open position;
- retaining the door in a closed position in the absence of a preset minimum level of water at the interior side;
- opening the door to the open position in a first direction in response to a pressure exerted by the preset minimum level of water present at the interior side;
- and
- preventing the door from opening to the open position in a second direction opposite of the first direction.
