ARTICULATION TO COUPLY, RESILIENTLY PIVOTING IN A FIRST ELEMENT TO A SECOND ELEMENT AND ARRANGEMENT TO TEMPORARILY COUPLE TOGETHER FIRST AND SECOND OPPOSITE CORRESPONDING ELEMENTS

摘要

A hinge pin (26) passes through a central lug (24) forming one hinge part. The other hinge part comprises two lugs (20, 22) flanking the central lug and having slots (54, 58) in which the hinge pin is loosely received. A U-shaped spring (28) has ends hooked round the ends of the hinge pin and a central part hooked over a central post (74) integral with the flanking lugs (20, 22). The spring urges the hinge pin into the slots (54, 58) but allows play in the hinge so that two halves (14, 16) of a housing, for example, can mate correctly without resort to precision engineering in these parts of the hinge.
