A door assembly (10) which in this case involves a generally rectangular door jam (11), a hinged door (12) comprising a pheripheral frame having vertical frame members (13 and 14) and horizontal frame members (15 and 16), the frame member (13) being hinged at (17 and 18) so that the door can swing within the door jam (11). The verticial member (14) includes a handle (19) and a lock assembly (20) so that the door can be locked from the inside. The figure is an inside view of the door assembly. The door assembly can be used for persons to enter and exit a structure. The structure can be a room, a building or it can be a main access door. The door assembly of the figure illustrates a single door, but most typically, the door assembly is employed as a security door in conjunction with a second door. In the illustrated embodiment, a security screen (21) infills between the frame members (13, 14, 15 and 16) and the frame member (14) employs a generally planer guard (22) protruding and covering a portion of the screen (21) adjacent the lock assembly (20). The guard (21) inhibits access from the outside through the screen (21) to the lock (20).
