Elevator trench drain
A trench drain includes a trench and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and the trench defines a trench volume therein. 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.
1. A trench drain comprising:
a trench having a base wall with peripheral side walls extending upwardly therefrom, the trench defining a trench volume therein;
a grating hingedly connected to the trench;
wherein the peripheral side walls of the trench have a pair of opposing elongated slots integrally formed therein and the grating has a pair of posts on opposing ends thereof and wherein 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;
wherein the pair of opposing elongated slots are formed by a wall extending generally perpendicularly from the peripheral side wall of the trench volume and wherein the wall forms a closed loop forming one of the slots into which one of the posts of the grating is received;
wherein the pair of elongated slots are elongated in the front to rear direction such that the grating is twistable relative to the trench to provide clearances for assembly of the grating to the trench by insertion of the pair of posts into the pair of opposing elongated slots.
2. The trench drain of claim 1 , wherein the trench drain is an elevator trench drain.
3. The trench drain of claim 2 , wherein the elevator trench drain is configured to be disposed proximate a lower edge of an elevator door.
4. The trench drain of claim 1 , wherein the peripheral side walls of the trench include two pairs of linear parallel segments such that the trench is rectangular in shape.
5. The trench drain of claim 1 , wherein the trench drain further comprises a drain passageway extending downwardly from the base wall of the trench and placing the trench volume in fluid communication with a lower opening of the drain passageway.
6. The trench drain of claim 5 , wherein the drain passageway is centrally aligned in the base wall of the trench.
7. The trench drain of claim 5 , wherein the drain passageway is offset from a center in the base wall of the trench.
8. The trench drain of claim 1 , further comprising a flange disposed outward of the peripheral side walls.
9. The trench drain of claim 1 , wherein a depth of trench drain exclusive of the drain passageway is 1.75 inches.
10. The trench drain of claim 1 , wherein the respective wall defining each of the pair of opposing elongated slots has two semi-circular segments connected by two linear segments.
