Rotatable shade umbrella

摘要

This invention provides a shade umbrella which is tiltable about a horizontal axis and which can be rotated about a vertical axis. A resiliently placed cam button protrudes through an opening adjacent each end of two annularly mated shaft portions supporting the umbrella. The button can be manually depressed to release the outer shaft, permitting removal of the umbrella or rotation for shaft control. A plurality of openings around the circumference of the outer shaft permits indexing of the shade control and the outer surface of the cam button is so shaped as to permit easy interconnection of the two shaft portions and secure locking thereof together.
