Abstract
A portable sign assembly having a base assembly which includes a leg member pivotally interconnected with a base plate of the base assembly. A leg release mechanism is further provided for selectively locking a respective leg from pivoting relative to a respective base plate. The release mechanism includes a lock-pin that is slidably disposed through the leg and is biased in a first position by a biasing member disposed within the leg. The lock-pin selectively engages apertures of the base plate for prohibiting pivotal motion between the leg and the base plate.
