ABSTRACT:
The present invention provides a collapsible sign apparatus that is readily portable and usable for temporary applications, wherein the apparatus is formed with a pair of hinged leg-support frame members which are adjustable controlled from a folded mode to a fully extended mode by means of a slidable frame member having guide members that movably engage the hinged leg-support frames. A stretchable elastic fabric is secured at its opposite ends to each respective leg-support frame member, the intermediate portion of the fabric being mounted for engagement with the slidable perpendicular frame member, whereby the elastic stretching of the fabric will bias the support frame members to a sustantially secure open position by placing an outward and upward force on the respective leg-support frame members. When in a folded position, the fabric is forced upwardly, thus preventing the leg-support frame members from moving to an open position, unless forced to do so against the fabric's spring-like tension.
