Access device, e.g. for mall entrance system, has door element movable against tensional force generator to initial force to open position when activated, then by force generator to end position, then automatically back to initial position

摘要

#CMT# #/CMT# The device (Z) has a door element movable about an essentially vertical axis (V) and supported on a support (T) by bearings and e.g. with a U-shaped tube. The door element can be moved from a null position to an open position when activated by a person. The door element, when activated by a person that is entering, is movable against the force of a tensional force generator to an initial open position, then by the force generator to a final open position and automatically swivels back to the initial open position #CMT#USE : #/CMT# Especially for entrance systems for supermarkets, malls etc. #CMT#ADVANTAGE : #/CMT# The convenience of the access provided is significantly improved without the use of an electric motor drive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective representation of an access device 1 : bush 2 : inner shaft T : support V : vertical axis Z : access device.
