ABSTRACT:
A frame for an umbrella has a shaft (4,5), ribs (7) extending radially from the top of the shaft, and stretchers (6) extending from a runner (2) on the shaft to attachment points on the ribs. The shaft comprises first and second parts (4,5) connected by a pivot or bending portion, e.g. a joint (1), located at a position between the top of the shaft and the runner (2) to allow the axis of the upper part of the shaft to be set in a position inclined to the axis of the part of the shaft below the pivot. This provides a stable tilting arrangement. Advantageously, the joint (1) can be a snap-in ball joint which is easy to assemble and manipulate.
