Locking mechanism for swivel doors - has lever actuated latch engaging with upper or lower door frame

摘要

The locking mechanism is used for a rotating panel door opened or closed by a piston and cylinder unit. This locking mechanism can be used for automatically actuated doors and swing doors. Such a door can be opened in either direction. On top or bottom of the door panel is arranged a catch (18) which engages with the given horizontal edge (6) of the door panel (1, 2). This catch (18) has a V profile. The catch (18) is held at one end of a lever (19) which in turn is able to rotate about a horizontal axis (22) on the door frame (3). The other end of the lever engages with an actuator (20) for moving the lever and catch between the locking and releasing positions.
