Emergency escape slide incorporated into exit

An emergency escape mechanism for a building having an exit door located within a doorway on an exterior of the building and elevated above ground level, the exit door having an interior side and an exterior side, said emergency escape mechanism comprising:

• an inflatable emergency escape slide having a portion coupled at an interior location of said building adjacent the interior side of the exit door, said escape slide comprising:
• a collapsed state wherein said escape slide is collapsed and resides against the interior side of the exit door when the door is closed;
• and
• an inflated state wherein said escape slide is inflated and extends through the doorway and downward outside of the building when the door is opened;
• an inertially-activated switch mounted on said inflatable emergency escape slide, said inertially-activated switch being activatable by gravity in automatic response to a dropping of said inertially-activated switch to thereby produce an electrical signal;
• a gas release device in fluid communication with said inflatable emergency escape slide and configured to inflate said inflatable emergency escape slide from collapsed state to said inflated state in automatic response to said electrical signal;
• and
• an alarm box configured to be located proximate the exit door, said alarm box including a locking/unlocking bar movable between a locked position and an unlocked position, said locking/unlocking bar engaging the exit door when said locking/unlocking bar is in said locked position to hold said exit door in a closed position, said locking/unlocking bar being movable in an emergency to move to said unlocked position to unlock the exit door, thereby enabling the exit door to be opened to extend out of the building, whereupon when said exit door is opened said emergency escape slide in said collapsed state passes through said open door and out of the building and drops under the influence of gravity, with the dropping of said emergency escape slide causing said inertially-activated switch to automatically operate to produce said electrical signal and to provide said electrical signal to said gas release device to automatically inflate said emergency escape slide to said inflated state.
