Description

The current application claims a priority to the U.S. Provisional Patent application Ser. No. 62/311,798 filed on Mar. 22, 2016.

FIELD OF THE INVENTION

The present invention relates to storm shelters and safe rooms. In particular, the present invention relates to an in-ground storm shelter that is accessible from inside of a trailer. The present invention provides a means to gain access to the storm shelter without exposing inhabitants to outside weather conditions.

BACKGROUND OF THE INVENTION

Manufactured homes and trailers are terms used to describe factory made homes that are built to specific standards set by the Department of Housing and Urban Development, the standards are also known as the HUD Code. These homes are built at the factory and transported to the customer's building site afterwards. Traditionally, manufactured homes are built on a steel I-beams with flatter roofs in order to meet clearance restrictions of bridges and overpasses. HUD Code manufactured homes, especially older models, have a reputation for being more susceptible to damages under extreme weather conditions such as high winds. The footings used under manufactured homes vary from concrete to bare soil. These homes are required to be anchored to the ground by various means. Generally speaking, these homes do not rest on perimeter foundations like site built homes and in many cases a vinyl material (skirting) is used for the perimeter crawl space protection instead of concrete.
Many owners of HUD Code manufactured homes have purchased storm shelters and safe rooms to mitigate the risk of bodily harm that can result from storms, tornados, and unwanted intruders. All of these shelters require the inhabitants to go outside in order to gain access to their shelter, thereby exposing themselves to high winds, rain, hail, flying debris, unwanted intruders, etc.
It is therefore an objective of the present invention to introduce a means for accessing an in-home in-ground storm shelter safely. The present invention is a storm shelter tunnel under a HUD Code manufactured home that is connected to the in-home in-ground storm shelter. The present invention allows inhabitants to avoid the risk of exposing themselves to weather elements and drastically reduces the time to gain entrance to the shelter. Access to the shelter is made through an opening in the floor of the home which leads to a stair block. The stair block connects the home to the shelter, leading downwards, allowing inhabitants to access a storm shelter door which is located just above ground or grade level. The stair block is walled off from the elements by an enclosure, allowing individuals to enter the storm shelter without being exposed to outside weather conditions. If a storm were to blow away the home, the stair block would disconnect from the home and storm shelter, but leave the storm shelter intact, with the inhabitants safe and unharmed inside.
