Patent ID: 6840253

Claim:
In a side post umbrella comprising a side post to which a side arm is mounted in a cantilevered manner and a shade mounted to and supported by the side arm, a shade rotating device mounted between the side arm and the side post for rotating the side arm and thus the shade, the shade rotating device comprising: a tubular member mounted to the side post and receiving an end of the side arm therein; a cylinder rotatably received in the tubular member and fixed to the end of the side arm to be rotatable in unison therewith; a drive bar pivotally connected to the cylinder for manually rotating the cylinder; a latch bar comprising a latch pin, the latch bar being movable with respect to the cylinder between a latched position and a released position, the latch bar being pivoted to the drive bar; biasing means arranged between the latch bar and the cylinder to bias the latch bar toward the latched position; and a securing plate defining at least one slot whereby when the latch bar is at the latched position, the latch pin engages the slot to secure the cylinder and thus the side arm at an angular position defined by the slot and whereby when the latch bar is at the released position, the latch pin disengages from the slot to allow for rotation of the cylinder with respect to the tubular member; wherein the drive bar and the pivotal connection between the drive bar and the cylinder forms a leverage that allows for manually driving the latch bar against the biasing means toward the released position.
