Floor safe

A safe assembly adapted to be received within an opening of a specified diameter formed within a rigid wall or floor and immovably retained therein comprising:

• a first sleeve having an axially extended tapered portion on its outer surface wherein one outer end of said first sleeve is of a first diameter and the other outer end is of a second and larger diameter, said second diameter being smaller than the receiving floor or wall opening;
• a container for storing deposited items within the safe assembly;
• means connecting the container to the first sleeve;
• a second sleeve having an inner diameter larger than the first diameter of the first sleeve but smaller than the second diameter of the first sleeve and being at least partially deformable;
• and
• locking closure means removably secured to the first sleeve for selectively enclosing the storage container of the assembly;
• and the first sleeve upon installation in the opening of a rigid wall or floor, engaging the second sleeve and radially expanding at least a portion of the second sleeve into rigid, essentially immovable engagement with the wall or floor surface bordering the opening within which the assembly is adapted to be placed and in a manner such that the application of extracting forces to any portions of the assembly exposed above such an opening will tend to increase the radially expansive forces upon the second sleeve in the opening thereby still further increasing the engagement forces between the first and second sleeves and the opening bordering surface and resisting extraction from the opening.
