摘要: A door assembly comprises a frame (6), a door (16) pivotally mounted on the frame (6), and door closing mechanism comprising a coil spring (20) an end portion (22) of which extends through an opening (24) in a frame member (8) and is attached (26) to the door (16) whereby, when the door (16) is opened, a length of the coil spring (20) is pulled through the opening (24) unwinding the spring (20) and the spring (20) tends to rewind to pull the door (16) closed. The spring (20) may be of the kind having a zero helix angle, a decreasing radius of curvature in the radially inward direction, and a significant axial depth, and preferably exerts a generally constant rewinding force.
