Patent ID: 8066021

Claim:
An umbrella assembly comprising: a cantilevered beam; an elbow comprising an upper potion coupled with the cantilevered beam and a lower portion, the lower portion defining a pathway therethrough and comprising a pin-slot; a fork comprising first and second tines disposed adjacent to opposite sides of and rotatably and translationally coupled to the lower portion of the elbow by a pin disposed between said tines and within said pin-slot, said fork defining a pathway therethrough; and a locking device for limiting the translation and rotation of the fork relative to the elbow, the locking device comprising: a stop projection disposed on the lower portion of the elbow; a stop projection receiving portion disposed on the fork that aligns with the stop projection when the pathways are aligned; a wedge shaped recess disposed on the lower portion of the elbow; and a wedge-shaped projection disposed on the fork that aligns with the wedge-shaped recess when the pathways are aligned; an elongated pulling member passing through the pathways of the elbow member and the fork; and a canopy assembly coupled with an end of the pulling member, wherein translation of the pulling member actuates the canopy assembly from a closed position to an open position and moves the stop projection into the stop projection receiving portion and moves the wedge shaped projection into the wedge-shaped recess to engage the locking device.
