Abstract

An aisle containment roof system includes a frame configured to be supported by two rows of racks or by the one row of racks and a wall or by a dedicated frame structure independent of the two rows of racks. The aisle containment roof system further includes a fixed perforated panel fixedly secured to the frame. The fixed perforated panel includes a pattern of openings formed therein. The aisle containment roof system further includes a movable perforated panel movably secured to the frame. The movable perforated panel has a pattern of openings corresponding to the pattern of openings of the fixed perforated panel. The aisle containment roof system further includes a mechanism configured to move the movable perforated panel relative to the fixed perforated panel to align the openings of the movable perforated panel to the openings of the fixed perforated panel.

First claim

What is claimed is:

1. An aisle containment roof system configured to span an aisle formed by two rows of racks or by one row of racks and a wall to form a ceiling, the aisle containment roof system comprising:
a frame configured to be supported by the two rows of racks or by the one row of racks and the wall or by a dedicated frame structure independent of the two rows of racks;
a fixed perforated panel fixedly secured to the frame, the fixed perforated panel including a pattern of openings formed therein;
a movable perforated panel movably secured to the frame, the movable perforated panel having a pattern of openings corresponding to the pattern of openings of the fixed perforated panel; and
a mechanism configured to move the movable perforated panel relative to the fixed perforated panel to align the openings of the movable perforated panel with the openings of the fixed perforated panel,
the movable perforated panel being configured to move between a closed position in which the pattern of openings of the fixed perforated panel and the pattern of openings of the movable perforated panel are offset with respect to one another and an opened position in which the pattern of openings of the fixed perforated panel and the pattern of openings of the movable perforated panel are aligned with respect to one another,
the mechanism including at least one spring assembly configured to bias the movable perforated panel to one of the closed and opened positions, and
wherein the at least one spring assembly includes a bracket secured to the frame, a bolt secured to the bracket, a washer provided on the bolt, and a compression spring disposed over the bolt and held in place between the bracket and the washer.

2. An aisle containment roof system configured to span an aisle formed by two rows of racks or by one row of racks and a wall to form a ceiling, the aisle containment roof system comprising:
a frame configured to be supported by the two rows of racks or by the one row of racks and the wall or by a dedicated frame structure independent of the two rows of racks;
a fixed perforated panel fixedly secured to the frame, the fixed perforated panel including a pattern of openings formed therein;
a movable perforated panel movably secured to the frame, the movable perforated panel having a pattern of openings corresponding to the pattern of openings of the fixed perforated panel; and
a mechanism configured to move the movable perforated panel relative to the fixed perforated panel to align the pattern of openings of the movable perforated panel with the pattern of openings of the fixed perforated panel,
wherein the movable perforated panel is configured to move between a closed position in which the pattern of openings of the fixed perforated panel and the pattern of openings of the movable perforated panel are offset with respect to one another and an opened position in which the pattern of openings of the fixed perforated panel and the pattern of openings of the movable perforated panel are aligned with respect to one another,
wherein the mechanism includes at least one spring assembly configured to bias the movable perforated panel to one of the closed and opened positions,
wherein the mechanism further includes an electromagnetic assembly configured to maintain the movable perforated panel in the other of the closed and opened positions and to release the movable perforated panel when a predetermined condition is detected.

3. The aisle containment roof system of claim 2 , wherein the electromagnetic assembly includes a bracket secured to the frame and an electromagnet positioned to engage the movable perforated panel.

4. The aisle containment roof system of claim 3 , wherein electromagnet is positioned to engage a metallic disc secured to a strip of metal extending from the movable perforated panel.

5. The aisle containment roof system of claim 2 , wherein the mechanism further includes an air cylinder configured to move the movable perforated panel back to one of the closed and opened positions.

6. The aisle containment roof system of claim 2 , further comprising a control module to control the operation of the electromagnetic assembly.

7. The aisle containment roof system of claim 6 , wherein the control module is configured to move the electromagnetic assembly between a magnetized condition in which the electromagnetic assembly retains the movable perforated panel in the other of the closed and opened positions and an de-magnetized condition in which the electromagnetic assembly releases the movable perforated panel to allow the movable perforated panel to move to the one of the closed and opened positions.

8. The aisle containment roof system of claim 7 , further comprising an alarm coupled to the control module and configured to activate when the electromagnetic assembly disengages the movable perforated panel.

9. The aisle containment roof system of claim 8 , further comprising at least one includes spring loaded plunger to secure the frame to a frame structure.
