ABSTRACT:
An umbrella frame has a pivotal connection between a crown or slider and canopy spokes or struts (1), respectively. The connection involves a sheet metal sleeve (3), which is carried on a stick (4) and has, integrally formed with it, an annular flange (5) and lobes (6). Each lobe comprises an axially extending inner section (6a) and an, initially outwardly extending, outer section (6b). During assembly, the outer sections are curled inwards about pivot pins(s) for the spokes or struts (1), which are seated in radius portions (R) at the junctions of the inner and outer lobe sections.
