A door assembly includes a door post 5 which is rotatable about a longitudinal axis 7 and is formed with a recess shaped to receive the side edge of a door 3. The door assembly may include a frame comprising a head rail between the door supporting door post 5 and a slam door post 4 and a means of enabling rotation of each door post relative to the head rail about a longitudinal axis. The means of rotation may be supporting the ends of the door posts within bearing races, or the end of each door post may carry a spindle which seats within a suitably shaped cap secured to the head rail. The door posts may be circular in cross-section and the depth of the recesses on the doorposts may be less than the circumference of the door posts. Preferably the shape of the recess complements the shape of the door edge, the recess may be "V" shaped. |
