Abstract

A mountable interlock security device for securing first and second sliding articles slidable relative to each other from an open position to a closed position such that in the closed position the sliding articles have overlapping interior edges. The security device comprises a first component mountable to the first sliding article and a second component mountable to the interior edge of the second sliding article. The two components of the security device are mounted to the overlapping end regions of respective sliding articles such that when the sliding articles are in the closed position, the two components of the security device cooperate to limit lateral movement of the sliding articles. In another aspect, a method of retrofitting interior and exterior sliding articles, such as doors or windows, of a building with a security device is provided.

Dependent claims

A mountable interlock security device for securing first and second sliding articles defining interior and exterior articles having a gap therebetween, the first and second sliding articles being slidable relative to each other from an open position to a closed position such that in the closed position each first and second sliding article has end regions that overlap the end region of the other sliding article, each end region being defined by an outer face and an inner face connected by an edge, an outer face of the first sliding article facing an inner face of the second sliding article, the security device comprising:

a first component mountable to at least a portion of the end region of the first sliding article, said first component having a one part of an interlocking mechanism for extending into the gap between the first and second sliding articles;
a second component mountable to the end region of the second sliding article, said second component including:
a bracket slidably mountable to the end region of the second sliding article;
said bracket having a channel facing the first sliding article and facing into the gap, said bracket being mountable adjacent the edge of the second sliding article;
an extendable member receivable in said channel for adjustably extending relative to said bracket in a sliding manner into the gap for accommodating different spacings between the first and second sliding articles;
and
an other part of the interlocking mechanism extending from an end portion of said extendable member into the gap between the first and second sliding articles;
wherein said one part of the interlocking mechanism of said first part cooperates with said other part of the interlocking mechanism of said second part for limiting lateral movement of the first and second sliding articles in the closed position upon the application of lateral force;
and
wherein the first and second components block the gap between the first and second sliding articles.

and
a two piece second component, a first piece of the two piece second component being mountable to the end region of the second sliding article;
a second piece of the two piece second component adjustably extending from the first piece into the gap between the first and second sliding articles to accommodate different spacings between the first sliding article and the second sliding article;
the second piece having another part of the interlocking mechanism, the another part of the interlocking mechanism extending from an end portion of the second piece;
wherein said one part of the interlocking mechanism said first part cooperates with said another part of the interlocking mechanism of said second part for limiting lateral movement of the first and second sliding articles in the closed position upon the application of lateral force;
and
wherein the first and second components block the gap between the first and second sliding articles.
