Abstract: A dual action retractable screen includes a first screen portion with a first screen portion perforated surface connected to the hinge mount via a horizontal hinge, which allows the first screen portion to rotate within a substantially horizontal plane. The screen also has a second screen portion with a second screen portion perforated surface and a latch pin. A vertical hinge connects the first screen portion to the second screen portion and allows the second screen portion to rotate within a substantially vertical plane. The screen also includes a latch mount that connects to the curb inlet and has a latch saddle that receives the latch pin. The screen operates in two modes: (1) a closed mode where the latch pin is disposed of in the latch saddle, inhibiting rotation about the horizontal hinge; and (2) an open mode where the latch pin is dislodged from the latch saddle, permitting rotation about the horizontal hinge and about the vertical hinge.

Abstract: The present invention comprises a sewer water gate to be located at the opening to a subsurface catch basin of a storm drain system that will exclude trash and debris from the system while still permitting a flow of water, but which will partially open to allow full access for water and entrained material when the rate of flow is sufficiently high while still obstructing the flow of heavier materials.
