Abstract
A hinge for mounting a door or like closure within a frame. The hinge comprises a first leaf pivotally coupled to a second leaf. The first leaf has a locating lug which interfits with a recess of the second leaf when the first and second leaves are at a predetermined angular disposition one to the other. This prevents a door mounted by the hinge from being removed from the frame even if the pin which pivotally couples the leaves together is forcibly removed. The first and second leaves are preferably coupled together by a coupling whereby the position of the second leaf relative to the axis of pivotal coupling can be selectively adjusted.
Claims13
A hinge comprising a first leaf pivotally coupled to a second leaf, said first leaf having locating means which interfit with receiving means of said second leaf when the first and second leaves are at a pre-determined angular disposition one to the other, said locating means being two lugs each of which interfits in a respective recess, each said recess being formed in a one of a pair of spaced apart projections carried by the second leaf, there being a pivot pin which passes through aligned openings in the projections and an opening in a part of the first leaf which is located between the projections, said first leaf part having said lugs.
A hinge comprising a first leaf and a second leaf, a mounting coupled to said second leaf for movement about a pivot axis by a pivot pin passing through the mounting, the first leaf having a flange which slidingly interfits with said mounting, and adjustment means comprising a threaded member engaged between first and second locating means associated respectively with said mounting and said flange, said threaded member being engaged in a threaded opening fixedly located with said first leaf such that rotation of the threaded member in said threaded opening applies a force to the first leaf to move the first leaf relative to the mounting.
