Abstract: A demountable hinge has a hinge pin held captive to a first hinge knuckle by a circlip and releasably held to a second hinge knuckle by a retaining screw threadedly engaged with the second knuckle and having a frusto-conical locking surface which makes a locking engagement with a frusto-conical surface on the hinge pin when the retaining screw is tightened. The engagement between the two frusto-conical surfaces urges the hinge pin axially of the second leaf to provide a firm engagement between a further frusto-conical surface on the pin and a complementary surface on the second knuckle. The hinge knuckles can be separated, for demounting a vehicle door, after partially unscrewing the retaining screw. In one construction in order to reduce the amount by which a door needs to be lifted for demounting, the second knuckle has a cut-out to permit the hinge pin to be disengaged from that knuckle after a reduced axial displacement of the knuckles.

Abstract: In a fastening for a door of a vehicle or freight container an operating bar mounted for angular movement about its axis on the door carries on at least one end a fastening member for engagement with a keeper on a door frame, and the said member has on one side of its axis a radially projecting fork for co-operation with one overhung lug projecting forwardly from the keeper, on the other side a radially projecting part for co-operation with a second forward projection on the keeper, and a radially projecting rib which, in the fully fastened condition of the mechanism, is received in a groove in the keeper between said forward projections.
