Modular closure unit
First Claim
1. A modular closure unit for use with a passageway defined by a frame in which said passageway is interposed between two adjacent floored rooms, said modular closure unit being operable to reversibly prevent passage between said rooms through said frame, said unit comprising:
- a first side wall;
a second side wall disposed in spaced relationship to said first side wall;
a back wall integrally connected to each of said side walls, each of said side walls and said back wall having an upper edge and a lower edge, said upper edges being disposed in coplanar relationship with each other to define an upper plane, said lower edges being in coplanar relationship with each other adjacent the floor disposed therebeneath;
a top member integrally attached to said upper edges of said walls; and
means for detachably securing each of said side walls to said frame to close said passageway and reversibly prevent passage between said adjacent rooms previously connected.

Abstract
A modular closure unit is described which has three walls, two of which are side walls each connected to the opposite vertical edges of the third or back wall. A top member is also integrally attached to the top edges of all three walls. Two discrete attachment means detachably attach the unit to the doorframe of an existing doorway in a wall to thereby close the doorway and prevent the unilateral removal of the unit by persons having access to only one side of the unit. The unit permits operable retention of the previously mounted door when desired.

8. A modular closure unit for semi-permanently closing off a doorway between adjacent rooms or for subdividing hallways which is detachably attachable to a doorframe which defines a doorway or to the walls which define a hallway, said modular closure unit comprising three walls integrally attached one on each side of the third wall;
- a top member integrally attached to each of said three walls and securing means for detachably attaching said modular closure unit to said doorframe or said walls to prevent said modular closure unit from being unilaterally removed from said doorframe or hallway by someone having access to only one side of said modular closure unit.

14. A method for reversibly closing off an existing passageway defined by an existing building frame and interposed between two adjacent, finished floored rooms to prevent passage between said rooms, said method comprising the steps of:
-
(a) moving a finished modular closure unit into position about said passageway to completely yet reversibly close off said passageway, said finished modular closure unit having a first side wall, a second side wall disposed in spaced relationship to said first side wall, a back wall integrally connected to each of said side walls, each of said side walls and said back wall having an upper edge and a lower edge, said upper edges being disposed in coplanar relationship with each other to define an upper plane, said lower edges being in coplanar relationship with each other adjacent the floor disposed therebeneath, and a top member integrally attached to said upper edges of said walls; and (b) securing said finished modular closure unit to said existing building frame about said passageway by inserting two independent sets of securing devices through the first and second side walls of said finished modular closure unit so that each securing device becomes embedded in said existing building frame, one of said two independent sets of securing devices attaching said unit to said frame from within one of said two adjacent rooms and the other of said two independent sets of securing devices attaching said unit to said frame from within the other of said two adjacent rooms. - View Dependent Claims (15, 16, 17, 18)
