BRIEF SUMMARY
TECHNICAL VIEW
This invention relates to flood or storm resistant barriers for doorways or window openings.
BACKGROUND ART
There are various situations where such barriers are required. For example, a flood resistant barrier may be required for an external doorway of a house or other building to keep out flood water, or for an internal doorway in a building to keep water which has accumulated on the floor in one room from passing to another room. A situation of the latter may occur in a building such as an art gallery or archive storage building where a water pipe has burst or a water sprinkler system has malfunctioned. Also, a fire may have occurred in one room and have been extinguished by a water sprinkler system or other fire extinguishing water supply. A storm resistant barrier may be required for boarding up a window when severe weather or possibly rioting or looting is expected.
Although many different kinds of barriers have been proposed for such purposes in the past, there is still a need for an improved barrier of this kind.
It is therefore an object of the invention to provide an improved flood or storm resistant barrier for doorways or window openings.
DISCLOSURE OF INVENTION
According to the invention, a flood or storm resistant barrier for a doorway or window opening comprises a frame having two parts, one of the frame parts having portions in telescopic engagement with the other frame part, and a manually operable jack mounted between the two frame parts and operable to move the two frame parts relative to one another to vary an external dimension of the frame and thereby enable the frame to be secured in a doorway or window opening by expansion of the frame into engagement with opposed surfaces of the doorway or window opening. A waterproof/stormproof barrier member is carried by at least one of the frame parts for blocking at least a portion of a doorway or a window opening when the frame is secured therein.
The manually operable jack may comprise four links pivotally connected to form a parallelogram linkage, one pair of opposed pivotal connections being mounted on respective frame parts, and the other pair of opposed pivotal connections being secured to holders through which a manually rotatable adjustment rod passes to enable the configuration of the linkage and hence the relative positions of the frame parts to be adjusted.
The barrier member may comprise a bag-like member containing the frame. Resilient sealing material may be provided between the frame and the bag-like member around at least the lower portion of the frame to ensure a sealing fit between the frame and the corresponding portions of a doorway. Alternatively, the barrier member may comprise a board-like member carried by one of the frame portions and extending beyond the periphery of the frame so as to cover a window opening when the frame is installed therein.
DESCRIPTION OF DRAWINGS
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings, of which:
