ABSTRACT:
An umbrella has a foldable canopy, an elongated boom having an end, a joint at the end connected to the canopy and suspending the canopy from the boom end, an upright mast having an upper end, and a fitting having a lower part fixed in the upper mast end, an upper part slidably receiving the boom. A pivot interconnects the upper and lower parts for pivoting of the upper part on the lower part about a horizontal axis between a deployed position with the boom extending transversely of the mast and a storage position with the boom extending generally parallel to the mast. A slide is longitudinally displaceable on the mast between a lower position in which it frees the upper part for pivoting between its storage and deployed positions and an upper position in which it engages the upper part in both the storage and deployed positions and positively retains the upper part therein.
