摘要

#CMT# #/CMT# The chamber (S) consists of a fixed outer cylindrical wall (6) with openings (9, 10) on opposite sides, and a rotary inner cylindrical wall (5) with a single opening (8) that is aligned with the outer wall openings in turn to allow people to pass through one at a time. The inner cylindrical wall rotates about a vertical axis that is offset relative to the door frame uprights, and the whole revolving chamber is set in a frame (13, 14) that pivots relative to an existing door frame so it can be put into service as and when necessary and locked in place. #CMT#USE : #/CMT# Controlling access to secure zones such as bank vaults, research institutions, hospitals and airports. #CMT#ADVANTAGE : #/CMT# The controlled access chamber can be set up at any time, using an existing doorway. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an overhead view of the controlled access chamber.
