(54)	Security door and frame assembly

(57) A security door and frame assembly comprises door 10 pivotally mounted in frame 20. Door 10 has interior and exterior surfaces and frame 20 has a slot 23 to receive bolt 30 mounted on the interior of door 10. Bolt 30 is operable between a first position in which it engages with frame 20 to secure door 10 in a closed condition, and a second position in which it is withdrawn from frame 20, allowing door 10 to pivot open. Lock 50 mounted on the interior of door 10 is operable between a locking condition in which it locks bolt 30 in said first position, and a release condition in which it allows bolt 30 to be released. Means accessible from both sides of door 10 are provided for moving bolt 30 between said first and second positions when lock 50 is in said release condition. Lock 50 is pivotable out of the plane of door 10 to release bolt 30 even when lock 50 is in its locking condition.
