Abstract:

A door assembly describing a stationary frame having doors mounted therein for relative translational movement. Each door includes a self-closing mechanism comprising a flexible tubular member affixed at one end to the frame and a follower secured to the other end of the tubular member for loose positioning in an active position adjacent a side of the door for urging the door in a closed position, and a self-opening means comprising a similar flexible tubular member affixed at one end to the frame and a follower secured to the other for loose positioning in an active position adjacent an opposite side of the door for urging the door to a fully open position. The self-closing and self-opening mechanisms both are adapted to be deactivated as an incident to positioning the door to respective locations within the mounting frame. The illustrated frame includes two telescopic inner fitting frame members that are adapted for mounting on variable thickness cabinet walls and which provide an inherent thermal barrier between the cabinet wall and the doors of the assembly.
