Abstract
The sign stand assembly includes a sign panel, support base and an upright mast between the two. The support base defines a locking recess and a hollow leg is pivotally connected to a plate portion and extending from the support base. The locking pin and actuator are carried within the hollow leg with the actuator carrying an outward protruding button. The actuator includes a medial portion defining an opening to receive the locking pin in interlocking engagement therewith.

A sign stand assembly comprising:
- a support base defining a locking recess, the support base providing support for the sign stand assembly;
- a leg comprising a hollow rigid tube pivotally attached to said support base;
- a locking pin extending through said tube for movement toward and away from the locking recess, said locking pin having an elongated, generally cylindrical body with a longitudinal axis;
- an actuator having first and second ends pivotally mounted within said tube for movement between first and second positions, said actuator defining an opening intermediate its first and second ends for receiving said locking pin in interlocking engagement therewith;
- a button carried on said actuator, extending from the first end of the actuator outside of the tube, said button engageable to move the actuator toward the second position;
- and
- a spring member within said tube urging the actuator to the first position thereby urging the locking pin toward the locking recess.
