Abstract
A fire shutter for protecting an opening 10, such as a window 12, having one or more (typically two) fire resistant panels 20 and 21. The panels are hinged along a horizontal portion of the opening such that at least one of the panels can be utilized as an awning when open. The panel(s) have an insulating core that typically provides thermal insulation from the elements and increases fire resistance from fires (such as bushfires) to provide a fire rated shutter that meets the highest building fire standards.
Claims16
A fire shutter for an opening, the fire shutter comprising at least one fire resistant upper panel having an insulating core, and at least one fire resistant lower panel having an insulating core, wherein the at least one fire resistant upper panel is hinged along an upper horizontal portion of the opening, and the at least one fire resistant lower panel is hinged along a lower horizontal portion of the opening, and wherein the panels are configured to cover the opening in a closed state and the at least one upper panel is configurable as an awning in an open state, wherein the at least one fire resistant upper panel has a suspension mechanism attached thereto with an end to be attached to a remote support surface to hold the at least one fire resistant upper panel in the open condition, the suspension mechanism includes a first elongate suspension member secured to the remote support surface, a second elongate suspension member secured to the at least one fire resistant upper panel, and a fusible link disposed between and secured to the first elongate suspension member and the second elongate suspension member, the fusible link being configured to separate at a predetermined elevated temperature to allow the at least one fire resistant upper panel to move to the closed condition due to gravity.
A fire shutter for a window or opening in a wall, the fire shutter comprising a fire resistant upper panel having an insulating core and being hinged in use to pivot about a first horizontal axis adjacent an upper portion of the opening, the upper panel being configured for use as awning when in an open state, a fire resistant lower panel having an insulating core and being hinged in use to pivot about a second horizontal axis spaced below the first horizontal axis, wherein the panels are configured to cover the opening when in a closed state, and a suspension mechanism attached the fire resistant upper panel and to a remote support surface to hold the fire resistant upper panel in the open condition, the suspension mechanism includes a first elongate suspension member secured to the remote support surface, a second elongate suspension member secured to the at least one fire resistant upper panel, and a fusible link disposed between and secured to the first elongate suspension member and the second elongate suspension member, the fusible link being configured to separate at a predetermined elevated temperature to allow the at least one fire resistant upper panel to move to the closed condition due to gravity.
