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.
Claims15
An elevator trench drain comprising:
- a trench including:
- a base wall,
- a drain passageway extending downwardly from the base wall to define a distal end opposite the base wall, wherein the drain passageway includes an upper section defining a first diameter proximate the base wall and a lower section defining a second diameter proximate the distal end, and wherein the ratio of the first diameter to the second diameter is between 1.3 to 1.7,
- a plurality of side walls extending upwardly from the base wall to define a first end,
- a plurality of secondary walls extending outwardly from the first end of at least a portion of the plurality of side walls to form a grate seat, and
- wherein the base wall, plurality of side walls, and plurality of secondary walls together at least partially define a trench volume;
- and
- a grate at least partially positionable within the trench volume, wherein the grate is configured to rest on and be supported by the plurality of secondary walls.
An elevator trench drain for use adjacent the threshold of an elevator, the elevator trench drain comprising:
- a trench including:
- a base wall,
- a drain passageway extending downwardly from the base wall to define a distal end opposite the base wall, wherein the drain passageway includes an upper section defining a first diameter proximate the base wall, a lower section defining a second diameter proximate the distal end, and an intermediate section extending between the upper section and the lower section, wherein the first diameter is greater than the second diameter, and wherein the axial length of the upper section is greater than the axial length of the lower section,
- a first wall extending from the base wall to produce a first distal edge,
- a second wall extending from the base wall opposite the first wall to produce a second distal edge,
- a pair of end walls extending from the base wall and extending between the first wall and the second wall,
- a first grate seat extending outwardly from the first distal edge,
- a second grate seat extending outwardly from the second distal edge, and wherein the base wall, the first wall, the second wall, the pair of end walls, the first grate seat, and the second grate seat at least partially define a trench volume;
- and
- a grate at least partially positionable within the trench volume, wherein the grate is configured to rest on and be supported by the first grate seat and the second grate seat.
