Abstract:
An improved hinge assembly for gates and/or doors, said hinge assembly including: a first member adapted, in use, to be affixed to either said door or gate or to a jamb therefor; second and third respective upper and lower members adapted, in use, to be affixed to either said jamb or to said door or gate, wherein said first member includes means allowing for selective horizontal adjustment of the location of said door or gate relative to said jamb therefor, and wherein at least one of said second and third members includes means allowing for selective vertical adjustment of the location of said at least one member relative to said jamb and/or to said first member and said associated door or gate, said first member further including a bore, extending in a substantially vertical direction therethrough, adapted to receive and releasably retain a pintle or shaft member, wherein said pintle or shaft member includes, at or in the vicinity of at least one free end thereof, a cam-like flat portion, and wherein use opposed free ends of said pintle or shaft member protrude outwardly from respective upper and lower free edges of said first member, to be releasably received by and within complementary-shaped bores of said second and third members, the arrangement allowing for pivotable movement of said first member relative to said second and third members, in turn giving rise to selective opening of closing of said door or gate, said hinge assembly further including means which allow for continuous monitoring of the spatial disposition of said door or gate relative to said jamb, to generate a visible and/or audible signal in the instance of said door or gate being ajar or pivotally displaced from said jamb, and wherein said means for generating said signal includes a retractable member adapted to protrude into said bore of said second member, to be in engagement with said pintle or shaft member located therein, the arrangement being such that, when said pintle or shaft member is rotated, as by pivotal movement of the door or gate, then when said cam-like flat portion is adjacent said retractable member said retractable member is released, thereby giving rise to generation of said signal.
