Heat releaseable ceiling support

A heat releasable bracket, for supporting a ceiling panel under normal conditions, and for releasing the ceiling panel when exposed to elevated temperatures caused by a nearby fire or the like, includes a first bracket part which includes a mounting portion for securing the first bracket portion to a support structure such as a beam, column, wall, etc.; a second bracket part which is adapted to be secured to the first bracket part and provide a support for the ceiling panel; and a heat releasable link which normally joins the first and second bracket parts together, but which releases the second bracket part from the first bracket part when exposed to elevated temperatures, which in turn allows the ceiling panel to drop away from the position at which it is normally supported. The heat releasable bracket can form part of an effective and relatively inexpensive ceiling panel support system comprised of at least one heat releasable bracket and at least one other bracket which is not heat releasable. The invention is useful for normally supporting a ceiling panel, but releasing it if a fire occurs so that it does not interfere with effective utilization of a sprinkler system located above the ceiling panel. |

DETAILED DESCRIPTION The invention provides a heat releasable bracket which can be used to support an overhead panel or baffle and which will release the same should a fire occur in the immediate vicinity thereof.
The heat releasable bracket of the invention is especially useful for supporting a ceiling panel or baffle at the upper end of a portable workspace module and releasing the panel or baffle if the temperature surrounding the heat releasable bracket reaches a predetermined elevated temperature.
In particular, by using a heat releasable bracket which will allow the ceiling panel or baffle to drop from the upper end of the workspace module if the surrounding temperature approaches or reaches the temperature at which a conventional overhead sprinkler system is activated, it is possible to arbitrarily position the workspace module in a room having a conventional overhead sprinkler system, and comply with any applicable fire safety requirements.
In accordance with one aspect of the invention, a heat releasable bracket is provided which has a first bracket part which is securable to a support structure, and a second bracket part which is attached to the first bracket part by a heat releasable link.
The second bracket part includes a surface onto which a ceiling panel or baffle can be supported.
The heat releasable link can generally be any linking device which can be used to hold the second bracket part in a fixed relationship with the first bracket part so that the ceiling panel or baffle is stablely supported on the bracket under ordinary conditions, and will release the second bracket part supporting the ceiling panel or baffle, if the temperature exceeds a predetermined level.
The present invention also provides a heat releasable ceiling panel support system for retaining a ceiling panel or baffle at the upper end of a workspace module under normal conditions, but which will allow the ceiling panel to drop from the upper end of the workspace module should the surrounding temperature exceed a predetermined level
