Waterproof storage unit

Abstract

A storage unit which is substantially water proof is provided. The storage unit may comprise a shell having lower edges which mate into a groove formed in a top surface of a base to provide a substantially waterproof barrier therebetween. The junction between the lower edge of the side walls and the first groove may be sealed with a water proof sealant. A front side wall of the shell may have an aperture therethrough to allow users to move items into and out of the storage unit. A door may be attached to the storage unit to prevent water from entering into the storage unit through the aperture. Moreover, a lower edge of the door body may be inserted into a second groove formed in the top surface of the base to prevent water from entering into the storage unit from under the door.

1 . A storage unit for storing items, the unit comprising: 
 a) a shell having a top, rear side wall, left side wall, right side wall and a front side wall which define lower edges, the front side wall having an aperture for moving items in and out of the unit;    b) a base defining a top surface having a first groove sized and configured to receive the lower edges to form a substantially water proof barrier between the side walls and the base, the top surface having a second groove; and    c) a door having a door body defining a bottom edge, the door traverseable between a closed position wherein the door body covers the aperture and the bottom edge is inserted into the second groove to prevent water from entering into the storage unit under the door body and an opened position wherein the door body is disposed away from the aperture and the bottom edge is removed from the second groove to allow items to be moved in and out of the storage unit.    
   
   
       2 . The unit of  claim 1  wherein a junction between the lower edges of the side walls and the first groove of the base is sealed with a waterproof sealant.  
   
   
       3 . The unit of  claim 2  wherein the junction is caulked with a water proof sealant.  
   
   
       4 . The unit of  claim 1  wherein the top, left side wall, right side wall, front side wall and the rear side wall are fabricated from a unitary material.  
   
   
       5 . The unit of  claim 1  wherein the base further has a ramp aligned with the aperture to allow items to be rolled into or out of the storage unit.  
   
   
       6 . The unit of  claim 1  wherein the top surface of base is raised substantially above ground level to maintain an interior storage area of the unit in a dry condition when the surrounding area outside the unit is flooded.  
   
   
       7 . The unit of  claim 1  wherein the shell, base and the door are resistant to salt water environments.  
   
   
       8 . The unit of claim I wherein a level of an outer perimeter of the top surface is lower than a level of a storage area.
