  • Patent number: 4269901
    Abstract: A shield for protection against fire consists of a flexible sheet of heat-insulating material having a resiliently flexible top stiffener secured across its top. Behind the sheet and secured to the top stiffener are two laterally spaced top handles arranged so one can be grasped by a hand, the other engaged and supported by the raised and more or less horizontal forearm, to hold the sheet, which has a window of transparent heat-resistant material, fully extended in front of the user. The sheet has a further transverse resiliently flexible stiffener across its middle part, and also a single central lower handle, and it may be weighted at its bottom.
