Door, designed not to deviate significantly from imaginary line between lock bolts used to secure it in frame

摘要

The door (2) never deviates from an imaginary line extending through the two lock bolts (6, 7) by a distance more than the distance between the door and stop (5) when the door is deformed in a curved manner. This maximum distance is e.g. 4-8 mm. The stop is formed by one of the door frame posts (3). The lock bolts are located at different heights and are used to lock the door in the frame.
