<p>A strike assembly includes a housing (12) adapted for mounting in a door jamb, and an exposed keeper (16) formed by plural keeper elements (16a, 16b) having opposed recesses (52) which co-operate in a bolt retention condition of the keeper to define a cavity (53) for a lockbolt. The keeper elements (16a, 16b) are mounted in the housing (12) for rotational movement, on respective axes (17a, 17b) parallel to the direction of movement of the bolt in and out of the cavity, between the bolt retention condition and a bolt release condition. A releasable latch (20) supported in the housing (12) for engaging the keeper elements (16a, 16b) and so preventing their rotational movement from the bolt retention condition.</p> |
