Closing sequence control for automatically closing two-leaf doors

摘要

The slide arm of the standing door panel is blockable in the closing direction by a locking device controlled by the standing panel (2) and having a detent (17) which interacts directly with the slide rail (9) or with a part rigidly connected with it. The slide rail has a recess or opening (19) or projection. The detent is mounted in a slide carriage (16) rotatable about its transverse axis and operable by a release mechanism (18) displaceable in the slide carriage. The slide carriage can be housed in the slide rail. The gangway door wing can only be completely closed when the standing wing is closed.
