Abstract
An improved compact warning sign and stand are disclosed which include apparatus for attaching and retaining the sign to an upstanding frame member of the stand. The preferred attachment apparatus includes a pair of channels on each of opposite sides of the frame member into which a vertical cross-brace on the sign may be inserted. The preferred frame member also includes means for permitting the sign panel to laterally pivot or swing under side-wind loads in order to allow a resilient portion of the frame base to deflect generally along a predetermined plane, thereby substantially preventing the sign and stand assembly from tipping over.
