Abstract: An improved warning sign and sign stand assembly is disclosed and includes apparatus for attaching and retaining the sign to a stand member of the assembly. The various embodiments of the assembly also include various mechanisms for permitting the sign panel to pivot or swing under side-directed loads in order to allow a resilient portion of the stand base to deflect generally along a predetermined plane, thereby substantially preventing the sign and stand assembly from tipping over. The various embodiments are applicable in sign and sign stand assemblies equipped with provisions for selectively collapsing the entire assemblies into compact and conveniently stored configurations, as well as being applicable in assemblies not so equipped.
