ABSTRACT:
A side post umbrella includes a side post to which a side arm is mounted by an arm retainer that is a tubular member receiving an end of the side arm therein. A rib skeleton is hung on the side arm and supports a shade. A shade rotating device is provided for rotating the side arm and thus the shade, including a cylinder rotatably received in the arm retainer and fixed to the side arm to be rotatable in unison therewith. A drive bar is pivotally connected to the cylinder for manually rotating the cylinder. A latch bar having a latch pin is movable with respect to the cylinder between a latched position where the latch pin engages a securing plate to secure the side arm and thus the shade at a corresponding angular position and a released position where the latch pin disengages the securing plate to allow for free rotation of the side arm and the shade. A helical spring is arranged between the latch bar and the cylinder to bias the latch pin toward the latched position. The drive bar is pivoted to the latch bar. The drive bar and the pivotal connection between the drive bar and the cylinder form a leverage that allows for manually driving the latch bar against the helical spring to release the latch pin. The securing plate may define a plurality of slots for selectively engageable by the latch pin to secure the shade at different angular positions.
