Abstract: A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and an outwardly-extending peripheral flange. The grating seat is configured to receive the grating. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench to establish an axis of rotation.

Abstract: An elevator trench drain includes a trench and a drain passageway. The trench has a base wall with peripheral side walls extending upwardly therefrom to define a trench volume therein. The drain passageway extends downwardly from the base wall of the trench and places the trench volume in fluid communication with a lower opening of the drain passageway. The drain passageway has a first section proximate the base wall defining a first cross-sectional area and a second section distal the base wall defining a second cross-sectional area. The second cross-sectional area is less than the first cross-sectional area and this reduction in cross-sectional area produces a head pressure that increases the flow out of the lower opening.
