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.
Claims20
A trench drain comprising:
- a trench including a base wall, a first wall extending from the base wall, and a second wall extending from the base wall, the base wall, the first wall, and the second wall at least partially defining a trench volume therein, the trench having a trench height, a trench length, and a trench width, the trench length is greater than the trench width, and the trench length is at least 60 times the trench height;
- a drain passageway extending through the base wall and including a distal end opposite the base wall, the distal end having an outlet, the outlet having an inner diameter that is no greater than 4 inches;
- and
- a grate at least partially positionable within the trench volume, the grate configured to allow fluid to pass therethrough.
A trench drain comprising:
- an elongated trench defining a trench volume therein, the elongated trench having a trench height, a trench length, and a trench width, the trench length is at least eight times the trench width, and the trench length is at least 60 times the trench height;
- a drain passageway open to the trench volume, the drain passageway extending away from the trench volume and including a distal end spaced apart from the trench volume, the distal end having an outlet, the outlet having an interior diameter that is no greater than 4 inches;
- and
- a grate at least partially positioned within the trench volume, the grate including a plurality of elongated openings through which fluid can enter the trench volume, the elongated openings having an opening length and an opening width, the opening length being greater than the opening width, and the trench length oriented substantially parallel to the opening length.
A trench drain comprising:
- an elongated trench defining a trench volume therein, the elongated trench having a trench height, a trench length, and a trench width, the trench length being greater than the trench width, the trench height is no greater than 1.75 inches, and the trench length is at least 60 times the trench height;
- a drain passageway open to the trench volume, the drain passageway extending away from the trench volume and including a distal end spaced apart from the trench volume;
- and
- a grate at least partially positioned within the trench volume, the grate including a plurality of elongated openings through which fluid can enter the trench volume, the elongated openings having an opening length and an opening width, the opening length being greater than the opening width, and the opening length being oriented substantially parallel to the trench length.
