Abstract
Disclosed is a self-closing sliding door assembly operable to allow manual opening and controlled automatic closing of a sliding door. The door assembly comprises storage spools for storing biasing members biased in a wound position around the storage spools. The door assembly further comprises a main spool for winding a cable and the biasing members. When the door is moved towards an open position, the cable is unwound from the main spool, causing the spool to rotate in a first direction. When the main spool is rotated in the first direction, the biasing members are wound onto the main spool and store energy operable to generate a force to cause the main spool to rotate in a second direction. When the door is released, the energy stored in the biasing members rotates the main spool in the second direction, thereby winding the door cable and providing a sufficient force to move the door towards the closed position.
