Door assembly and method of replacing a door of an electronics cabinet

A rack enclosure comprising:

• a frame configured to define an interior suitable for supporting electronic equipment, the frame having at least one opening to allow access into the interior;
• a first door and a second door, the first door being hingedly secured to the frame on one side of the at least one opening and the second door being hingedly secured to the frame on an other side of the at least one opening, the first and second doors being individually movable between an open position to allow access to the interior and a closed position to block access to the interior, the second door having a height substantially coextensive with a height of the frame and the first door having a height less than the height of the frame, wherein a space is defined between at least a portion of the first door and the frame when the first door is closed;
• a latch assembly secured to the second door, the latch assembly including a handle coupled to the second door,
• a detent member coupled to the handle, the detent member being movable from a retracted position to an extended position proximate an inside surface of the first door when the doors are in their closed positions and the handle is actuated;
• and
• a bracket secured to an inside surface of the second door proximate to the portion of the first door defining the space between the first door and the frame when the first door is closed.

A retrofit kit for a rack enclosure of the type comprising a frame configured to define an interior suitable for supporting electronic equipment, the frame having at least one opening to allow access into the interior, a first door, a second door, the first door being hingedly secured to the frame on one side of the at least one opening and the second door being hingedly secured to the frame on an other side of the at least one opening, the first and second doors being individually movable between an open position to allow access to the interior and a closed position to block access to the interior, the first door having a height less than a height of the second door, and a latch assembly secured to the second door, the latch assembly including a handle rotatably coupled to the second door between an open position and a locked position, a first shaft portion coupled to the handle, and a second shaft portion coupled to the handle, the first and second shaft portions being configured to engage the frame when the first and second doors are in their closed positions and the handle is rotated to its locked position, the first door including a flange configured to overlap an edge of the second door when the first and second doors are in their closed positions, the retrofit kit comprising:

• a detent member constructed and arranged to couple to the handle, the detent member constructed and arranged to be movable from a retracted position to an extended position when rotating the handle from its open position to its locked position;
• and
• a bracket constructed and arranged to be secured to the first door, the bracket having an opening formed therein arranged to receive the detent member when the detent member is moved by the handle to its extended position when the first and second doors are in their closed positions.

A retrofit kit for doors of an electronics cabinet comprising:

A method of replacing a door of an electronics cabinet, the method comprising:

• providing a first door having a height less than a height of a frame of the electronics cabinet;
• attaching the first door to the frame of the cabinet;
• and
• installing a latch assembly on a second door, the latch assembly including one or more lock rods and a detent member configured to selectively engage the first door.

A rack enclosure comprising:

• a frame configured to define an interior suitable for supporting electronic equipment, the frame having at least one opening to allow access into the interior;
• a first door and a second door, the first and second doors being individually movable between an open position to allow access to the interior through the at least one opening and a closed position to block access to the interior, the second door having a height substantially coextensive with a height of the frame and the first door having a height less than the height of the frame, wherein a space is defined between at least a portion of the first door and the frame when the first door is closed;
• a latch assembly secured to the second door, the latch assembly including a handle coupled to the second door,
• a detent member coupled to the handle, the detent member being movable from a first position to a second position upon actuation of the handle, and
• a slot formed in the first door proximate to the portion of the first door defining the space between the first door and the frame when the first door is closed, the slot configured to receive the detent member when the detent member is moved by the handle to its second position when the first and second doors are in their closed positions.
