ABSTRACT:
The assembly includes an integral corner door and a latch assembly, the latch assembly including a user acuatable element, a dog-ear element, a cam receiving element and a door extension. The integral corner door has a hinging portion hingedly connected to a first surface of the housing and a latching portion perpendicular to the hinging portion connectable to a second surface of the housing. The user actuatable element has a user manipulative portion and a rotatable shaft affixed thereto. The user manipulative portion is positioned on the second surface of the housing. The shaft extends through an opening through the second surface. The dog-ear element of the latch assembly is securely affixed to the shaft. The dog-ear element has a first hooked end and a second end. The first hooked end forms a recess. The hooked end has a terminal cam portion. The second end includes a door disengaging portion. The cam receiving element of the latch assembly is located on the latching portion of the corner door for receiving the terminal cam portion of the dog-ear element when the shaft has been rotated sufficiently, thus securing the corner door in a latched position. The door extension of the latch assembly is located on the latching portion of the corner door. It is urged against by the door disengaging portion when the shaft has been sufficiently counter rotated, thus pushing the corner door open. The door extension rotates the dog-ear element away from the corner door when a user closes the door as preparatory to locking it, thereby obviating the need for the user to manually rotate the shaft in order to close the door and thus avoiding potential damage of the dog-ear element.
