<p>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.</p> |
