Filed:

Feb 24, 2016
Appl. No.:

15/052741
Inventors:

- Oceanside CA, US
Ernest Jarvis - Norco CA, US
International Classification:

E03F 5/046
E03F 5/06
E03F 5/04
Abstract:

Embodiments of the disclosure provide resistance hanging screens, configured for installation into a storm drain or a component of a storm drain, that comprise a front plate and first and second hanging pivots. The combination of the location of the center of gravity of the resistance hanging screens and the first and second hanging pivots confers a bias of the resistance hanging screens to occupy a closed position when the resistance hanging screen is installed in the storm drain or the storm drain component.

Filed:

Oct 11, 2013
Appl. No.:

14/051447
Inventors:

Ernest Jarvis - Norco CA, US
International Classification:

E03F 5/04
E03F 5/06
E03F 1/00
E02B 5/08
US Classification:

210131
Abstract:

Embodiments of the invention provide automatically retractable screens, adapted for installation into a storm drain curb inlet, configured such that the automatically retractable screens are biased toward the closed position and thereby reliably closed during periods of no, low, or moderate surface runoff water flows, yet also reliably open when surface runoff water flow rates increase to moderate or high levels.
