Joint element for ribs of umbrella, made of metal and comprising three joining areas

摘要

The element (1) is inserted between every two pairs of individual ribs of the five different sets of ribs (2, 3, 4, 5, 6). It is made all of a piece of cast metal. Two semi-circular segments are located laterally in the center of the element (1) and are provided with holes and a longitudinal groove between them. A slightly upwards bent segment with a transversal bore is positioned at the rear of the element (1). The tapering front has a rounded outer surface and a central bore for the insertion of the end of one of the filigree ribs (3, 4, 5).
