Abstract
The double closure sprung butt hinge connects the articulating leaves of a folding door, using a tubular pin with end caps connected by an axial clipped stack of blade springs. Two pins connect the respective vertical edges of a rectangular centre plate to those of two drilled side plates, each locating staggered tubular centre and side plate knuckles. The caps are slotted to locate the ends of the spring stack. They have a radial bore, and enlarged heads providing knuckle retaining shoulders. Holes are used to pin the caps to the top side plate and the bottom centre plate knuckles respectively.
