ABSTRACT:
An assistant ceiling device designed to shield an escape hatch installed to a ceiling of an elevator cab is provided. The assistant ceiling device includes two elongated rail guides and a rectangular assistant ceiling plate. Each guide is installed at either side of the emergency escape hatch and has a length longer than that of the emergency escape hatch and shorter than that of the ceiling of the elevator cab. The assistant ceiling plate is laid on the rail guides to shield the emergency escape hatch. Each guide has a latching jaw so as to allow the assistant ceiling plate to be installed to the rail guides by laying both sides of the ceiling plate on the latching jaws.
