Abstract
A door pivot assembly comprising two portions. One portion is attached to a support beam for the door and has a vertical cylindrical pivot bearing and horizontal bearing surface. A V-shaped groove is formed on the bearing surface defining the closure plane of the door. The second portion of the assembly is attached to the door and has a pin for engaging the cylindrical bearing of the first portion. A V-shaped rib is provided on the first portion extending normal to the pin and at an angle to the door closure plane. This rib engages the groove of the first portion when the door is closed and biases the door towards a closed position.
