Abstract
A closure includes a rolling grille of the glazed type. A plurality of rods are pivotally retained in parallel, spaced-apart relationship by a plurality of strings of link assemblies. Each link assembly is formed by two identical link elements journaled upon adjacent rods in back to back relationship. A panel is disposed between each pair of adjacent rods and has its ends secured to attaching means integral with each link element. Ready fabrication and subsequent smooth quiet operation is assured by forming the link elements of a synthetic resin composition such as nylon plastic.
