Abstract
A storm shelter is provided having a modular rectangular shelter housing. An egress port extends slightly above the shelter housing, such that the housing can be buried underground with the egress port extending slightly above ground. A reinforced, sliding access door is mounted at the egress port, and a stairway is provided to allow descent into the shelter housing. A plurality of seat boxes is provided which can be utilized to contain tools, supplies, or the like, with a seat lid pivotally mounted in a hinged manner to each seat box. Each step is provided with a non-skid surface, and is sufficiently large enough to provide a seating surface. The top stair has an accessible cut-out panel for allowing an emergency jack to pass through. An emergency jack can be utilized to forcibly remove the door, should the door become stuck or blocked from the outside.

Description
Background of the Invention
1. Field of the Invention
The present invention relates generally to storm shelters and, more particularly, to an underground, modular storm shelter.
2. Description of the Related Art
In the related art, several storm shelters are known. For example, in U.S. Pat. No. 4,955,166 to Qualine et al. a tornado underground shelter is disclosed having a truncated globe forming a generally spherical tornado shelter.
And, in U.S. Design Pat. No. 337,166 to Kluzek an ornamental design for a storm cellar is disclosed. Also, in U.S. Design Pat. No. 261,432 to Ballard an ornamental design for an emergency shelter for underground installation is disclosed. And finally, in U.S. Design Pat. No. 242,924 to McKnight, an ornamental design for an underground tornado shelter is also disclosed.
Although numerous attempts have been made to provide a safe, strong, inexpensive, and easy to manufacture storm shelter, a need remains for providing an apparatus and kit which provide such attributes.
Summary of the Invention
It is therefore an object of the present invention to provide an improved storm shelter.
It is another object of the present invention to provide an improved storm shelter being modularly designed in order to provide for the coupling together of standard sized units to provide increased capacity.
It is a feature of the present invention to provide an improved storm shelter having a sliding access door with an emergency egress jack capable of removing the door to provide egress should the door become obstructed during a storm.
Briefly described according to one embodiment of the present invention, a storm shelter is provided having a modular rectangular shelter housing. An egress port extends slightly above the shelter housing, such that the housing can be buried underground with the egress port extending slightly above ground. A reinforced, sliding access door is mounted at the egress port, and a stairway is provided to allow descent into the shelter housing. The stairway consists of a pair of parallel stair stringers containing a plurality of steps, each having a non-skid upper surface. The top stair has an accessible cut-out panel for allowing an emergency jack to pass through. The emergency jack can be utilized to forcibly remove the door, should the door become stuck or blocked from the outside. Within the shelter housing are located a plurality of seat boxes. Each seat box can be utilized to contain tools, supplies, or the like. A seat lid is pivotally mounted in a hinged manner to each seat box. Each seat lid is provided with a padded surface, and is sufficiently large enough to provide a seating surface.
An advantage of the present invention is that the storm shelter can be buried, thereby minimizing its profile and providing an aesthetically more pleasing structure.
Another advantage of the present invention is that each stair comprises both storage and seating capacity.
Further, a preferred embodiment of the present invention has an emergency jack which can be utilized to forcibly remove the door, should the door become stuck or blocked from the outside

FIG. 7 is a side elevational view of a storm shelter according to an alternate embodiment of the present invention.
Detailed Description
Referring now to FIG. 1, a storm shelter 1 is shown, according to the present invention, having a modular rectangular shelter housing 2. As shown in FIG. 1, the storm shelter 1 can be placed within the ground on a concrete slab 4 and mounted thereto by first anchoring means 6. A concrete slab 4 would prevent hydrostatic lift of the storm shelter 1, as well as provide a leverage surface for an emergency jack 24, as will be described later. An egress port 8 extends slightly above the shelter housing 2, such that the housing can be buried underground with the egress port 8 extending slightly above ground. A reinforced, sliding access door 10 having a pair of handles 11 (one mounted each to the outer and inner surface) is mounted at the egress port 8. A plurality of seat boxes 16 are also provided within the shelter housing 2. Each seat box 16 can be utilized to contain tools, supplies, or the like. A seat lid (not shown) is pivotally mounted in a conventional hinged manner to each seat box 16.
As shown more clearly in FIG. 2, a stairway 20 is provided to allow descent into the shelter housing 2. The stairway 20 consists of a pair of parallel stair stringers containing a plurality of steps 22. The bottom step 22a is affixed to the floor of the shelter housing 2, and the top step 22b is affixed to the wall of the egress port 8. Each step 22 is provided with a non-skid surface.
As shown in FIG. 3, the top step 22b has an accessible cut-out panel 30 held in place by extended tabs 32, for allowing the emergency jack 24 to pass through. The emergency jack 24 can be utilized to forcibly remove the door 10, should the door 10 become stuck or blocked from the outside.
FIG. 4 and FIG. 5 show in greater detail the construction of the egress port 8 and sliding door 10. To one side of the egress port 8 is a door stop 40. Perpendicularly to the door stop 40 are a pair of parallel slotted slide rails 42, each extending past an entryway 44 within the egress port 8. As shown more clearly in FIG. 5, a pair of tracks 50 are mounted to the inside surface of the door 10, and extend downward in an aligned manner to insert within the slots 43 of the slotted slide rails 42.
As shown in FIG. 6, a first door stop 60 protrudes slightly upwards above the slots 43, and form an impact barrier to the rails 50 when the door 10 is closed. Further, a second door stop 62 and a third door stop 64 are provided affixed to the inside surface of the door 10, to further form an impact barrier between the doors stops 62, 63 and the vertical sidewalls of the egress port 8.
In accordance with a preferred embodiment of the present invention, as shown in the figures, the storm shelter 1 can be used as a retreat from danger caused by weather, temperature, or other disasters. Further, as depicted in FIG. 7, additional shelter space can be achieved by coupling a plurality of the modular rectangular shelter housings 2 together.
The foregoing description is included to describe embodiments of the present invention which include the preferred embodiment, and is not meant to limit the scope of the invention. From the foregoing description, many variations will be apparent to those skilled in the art that would be encompassed by the spirit and scope of the invention. Accordingly, the scope of the invention is to be limited only by the following claims and their legal equivalents.
