DESCRIPTION:
BRIEF SUMMARY
The invention relates to a security closure for use in protecting windows and like openings in temporarily unoccupied premises.
Property which is temporarily vacant for one reason or another, for example, during building renovation or between tenancies is being increasingly subject to damage due to theft and vandalism. Early attempts to protect such property involved securing wooden or reinforced panels to the outer skin of the building around the opening. The means of fixing the panels have proved to be easily accessible from the outside and so lacking in security.
A recent proposal of security closure comprises a panel having a shallow peripherally extending side wall having inwardly turned rim portions extending along opposed parallel sides of the panel and formed and arranged for captively retaining respective end portions of at least two support members so as to permit lateral sliding movement of the support members in a direction parallel to the opposed sides while restraining them against movement perpendicular to the principal plane of the panel. At least two spaced apart elongate connector means are connected to each of the support members and anchor means are provided having a length not substantially less than the length or width of the panel. The connector means and anchor means are formed and arranged for securing the connector means to the anchor means so as to clamp an opening surround between the panel side wall and the anchor means with the anchor means extending generally parallel to the panel.
Since the means of fixing the panels are not easily accessible from outside, security is enhanced. However, the provision of the captive but slidable support members with the panel is a somewhat elaborate and expensive feature.
According to the present invention there is provided a security closure comprising a panel having inner and outer sides, holding means rigidly secured to or formed on the inner side of the panel, anchor means of a length not substantially less than the height or width of the panel, and at least two spaced apart elongate connector means interconnecting the holding means on the panel and each of the anchor means, each connector means being adapted at one end to be releasably engaged with said holding means and being so connectable with the anchor means as to clamp an opening surround between the panel inner side and the anchor means with the anchor means extending generally parallel to the panel.
Such a structure is easy to assemble and yet provides all the necessary security. Because the holding means are rigidly secured to or formed on the inner side of the panel there can be no possibility of their moving either during or after installation thereby facilitating installation and improving security.
The panel can have any form but preferably has a shallow peripherally extending side wall having an inwardly turned rim. The holding means may comprise formations integral with the panel near the periphery thereof, but concealed by the side wall for example being formed on said side wall or on said inwardly turned rim.
Preferably, in order to ensure that the connector means do not move laterally and again to improve security, the holding means define a plurality of spaced holding locations and said one end of said connector means is adapted to be releasably engaged with one of said spaced holding locations. Such a structure may take many forms and one of these are a number of apertures, notches or the like formed in the rim or in the side wall either integrally therewith or by tabs secured to or formed integrally with the side walls.
An alternative approach is for the holding means to include at least one bar extending across said inner side of the panel, said bar being provided with a plurality of spaced projections or recesses to define said plurality of spaced holding locations. The or each bar may be secured to the inner side of the panel at any location but preferably it is secured to the side wall and/or to the side wall rim.
