Abstract
Disclosed is a hatch assembly with a gasket that seals when the hatch is closed. The sealed hatch assembly is fluid tight and prevents water, dust, or other contaminates from entering the enclosure protected by the hatch. In a preferred embodiment, the gasket is formed about a peripheral edge of the hatch door. This gasket is adapted to seat upon an L-shaped bracket formed about the periphery of the hatch frame. A center beam is also included for dividing the frame into two openings. The center beam includes a U-shaped bracket that can also form a seal with the gasket. The various components of the present disclosure, and the manner in which they interrelate, will be described in greater detail hereinafter.
Claims10
A sealed hatch assembly (10) adapted to secure an opening (12) for an underground enclosure (14), the hatch assembly (10) comprising:
- a frame (22) having opposing lengthwise and widthwise edges (24, 26), each of the edges having a length, the opposing lengthwise edges having a midpoint (28), the frame dimensioned to be secured within the opening (12) of the underground enclosure (14), an inner peripheral extent (32) formed along the entire length of the opposing lengthwise and widthwise edges (24, 26), an upstanding L-shaped bracket (34) formed within the inner peripheral extent (32);
- a center beam (36) extending between the opposing lengthwise edges (24) of the frame at the midpoint (28), the center beam (36) including an upstanding U-shaped bracket (38) extending between the opposing lengthwise edges (24), the center beam dividing the frame into two openings (42, 44);
- a pair of opposing doors (46, 48), each of the doors (46, 48) being pivotally secured to one of the opposing widthwise (26) edges via a hinge assembly (52) and having an opened and closed position over a respective opening (42, 44), each of the opposing doors (46, 48) including a peripheral edge (54), a silicone gasket (56) formed within the peripheral edge (54) of each of the opposing doors (46, 48), the silicone gasket (56) adapted to engage the L-shaped (34) and U-shaped (38) brackets for form a fluid tight seal.
A hatch assembly adapted to secure an opening for an enclosure, the hatch assembly comprising:
- a frame having opposing edges, the frame dimensioned to be secured within the opening, an upstanding bracket formed along an extent of the frame;
- a door pivotally secured to one of the opposing edges via a hinge assembly and having an opened and closed position over the opening, the door including a peripheral edge, a gasket formed along an extent of the peripheral edge, the gasket adapted to engage the upstanding bracket when the door is closed to form a fluid tight seal.
A hatch assembly for an opening comprising:
- a frame having a peripheral extent, the frame dimensioned to be secured within the opening, an upstanding bracket secured along the entire peripheral extent of the frame;
- a door pivotally secured to the frame via a hinge assembly, the door and having opened and closed positions over the opening, the door including a peripheral channel, a gasket secured within the peripheral channel, the gasket adapted to engage the upstanding bracket when the door is closed.
