Abstract

An electronics cabinet includes an enclosure comprising a floor, a ceiling, a rear wall, and opposed side walls configured to form an internal cavity a door assembly attached to one of the side walls. The door assembly includes: a main door pivotally connected to the enclosure, the main door including a window, the main door being movable between a closed position and an ajar position; and a plurality of door panels, the door panels pivotally connected with each other, at least some of the door panels being pivotally and slidably attached to the main door, the door panels configured to move from an unfolded position, in which the door panels are generally coplanar and block access to the window, and a folded position, in which the door panels are generally parallel and non-coplanar. The main door and door panels are configured so that the door panels cannot move from the unfolded position to the folded position unless the main door is in the ajar position.

First claim

That which is claimed is:

1. An electronics cabinet, comprising;
an enclosure comprising a floor, a ceiling, a rear wall, and opposed side walls configured to form an internal cavity;
a door assembly attached to one of the side walls, the door assembly comprising:
a main door pivotally connected to the enclosure, the main door including a window, the main door being movable between a closed position and an ajar position, wherein in the ajar position the main door is pivoted between about 3 and 15 degrees from the closed position; and
a plurality of door panels, the door panels pivotally connected with each other, at least some of the door panels being pivotally and slidably attached to the main door, the door panels configured to move from an unfolded position, in which the door panels are generally coplanar and block access to the window, and a folded position, in which the door panels are generally parallel and non-coplanar and permit access to the window;
wherein at least one of the door panels includes a recess in a front surface thereof.

2. The electronics cabinet defined in claim 1 , wherein the main door and the door panels are configured such that the door panels are prevented from moving to the folded position when the main door is in the closed position.

3. The electronics cabinet defined in claim 1 , further comprising a locking assembly on the main door, the locking assembly securing the main door in the closed position.

4. The electronics cabinet defined in claim 3 , wherein the locking assembly prevents the door panels from moving to the folded position.

5. The electronics cabinet defined in claim 1 , wherein a first endmost door panel is pivotally mounted to the main door but is not slidably mounted to the main door.

6. The electronics cabinet defined in claim 5 , wherein a spring-loaded plunger is mounted to a second endmost door panel, the plunger maintaining the door panels in the unfolded position unless released.

7. The electronics cabinet defined in claim 1 , wherein at least one door panel includes a gasket on a side edge thereof that engages a side edge of an adjacent door panel to form a seal therewith.

8. The electronics cabinet defined in claim 7 , wherein the gasket resides within a recess in the side edge of the door panel.

9. The electronics cabinet defined in claim 1 , wherein at least one of the door panels includes a plurality of fins on a front surface thereof that forms a heat sink.

10. The electronics cabinet defined in claim 1 , wherein in the ajar position, the main door extends between about 4 and 8 inches forwardly of its position in the closed position.

11. An electronics cabinet, comprising:
an enclosure comprising a floor, a ceiling, a rear wall, and opposed side walls configured to form an internal cavity; and
a door assembly attached to one of the side walls, the door assembly comprising:
a main door pivotally connected to the enclosure, the main door including a window, the main door being movable between a closed position and an ajar position; and
a plurality of door panels, the door panels pivotally connected with each other, at least some of the door panels being pivotally and slidably attached to the main door, the door panels configured to move from an unfolded position, in which the door panels are generally coplanar and block access to the window, and a folded position, in which the door panels are generally parallel and non-coplanar;
wherein the main door and door panels are configured so that the door panels cannot move from the unfolded position to the folded position unless the main door is in the ajar position.

12. The electronics cabinet defined in claim 11 , wherein in the ajar position, the main door extends between about 4 and 8 inches forwardly of its position in the closed position.

13. The electronics cabinet defined in claim 11 , further comprising a locking assembly on the main door, the locking assembly securing the main door in the closed position.

14. The electronics cabinet defined in claim 13 , wherein the locking assembly prevents the door panels from moving to the folded position.

15. The electronics cabinet defined in claim 11 , wherein a first endmost door panel is pivotally mounted to the main door but is not slidably mounted to the main door.

16. The electronics cabinet defined in claim 15 , wherein a spring-loaded plunger is mounted to a second endmost door panel, the plunger maintaining the door panels in the unfolded position unless released.

17. The electronics cabinet defined in claim 11 , wherein at least one door panel includes a gasket on a side edge thereof that engages a side edge of an adjacent door panel to form a seal therewith.

18. The electronics cabinet defined in claim 17 , wherein the gasket resides within a recess in the side edge of the door panel.

19. The electronics cabinet defined in claim 11 , wherein at least one of the door panels includes a plurality of fins on a front surface thereof that forms a heat sink.

20. An electronics cabinet, comprising:
an enclosure comprising a floor, a ceiling, a rear wall, and opposed side walls configured to form an internal cavity;
a door assembly attached to one of the side walls, the door assembly comprising:
a main door pivotally connected to the enclosure, the main door including a window, the main door being movable between a closed position and an ajar position, wherein in the ajar position the main door is pivoted between about 3 and 15 degrees from the closed position;
a plurality of door panels, the door panels pivotally connected with each other, at least some of the door panels being pivotally and slidably attached to the main door, the door panels configured to move from an unfolded position, in which the door panels are generally coplanar and block access to the window, and a folded position, in which the door panels are generally parallel and non-coplanar and permit access to the window; and
a stay bar attached between the main door and the enclosure that limits the main door to opening only to the ajar position.
