Secure box assembly and related methods

A secure box assembly for a floor structure, the secure box assembly comprising:

• a frame body anchored between joists within the floor structure and defining a cavity therein, an uppermost portion of the frame body being aligned with an upper surface of the floor structure;
• a door having a first major surface facing the cavity of the frame body, a second major surface opposite the first major surface, and a cover layer carried by the second major surface, the cover layer matching the upper surface of the floor structure;
• first and second hinges coupled between the frame body and the first major surface;
• and
• at least one powered arm coupled between the frame body and the first major surface and configured to pivot the door between an open state and a closed state, the door being flat and flush with the upper surface of the floor structure in the closed state.

A method for making a secure box assembly for a floor structure, the method comprising:

• forming a frame body to be coupled between joists within the floor structure and defining a cavity therein, an uppermost portion of the frame body being aligned with an upper surface of the floor structure;
• positioning a door having a first major surface facing the cavity of the frame body and a second major surface opposite the first major surface;
• coupling a hinge assembly between the frame body and the first major surface;
• and
• coupling at least one powered arm between the frame body and the first major surface and configured to pivot the door between an open state and a closed state, the door being flat and flush with the upper surface of the floor structure in the closed state.
