Abstract: A sign stand for supporting highway safety signs or the like. The stand includes a plurality of folding legs which support the stand on the ground. The legs support a socket having an open upper end to receive the mounting bracket formed at one corner of a side. A latch mechanism includes a hook normally extending within the socket, and cammed to one side as the mounting bracket enters the socket. The lever extends laterally from a side of the socket, enabling withdrawal of the hook to remove the sign.

Abstract: A flexible message sign particularly intended for highway or roadway applications, and having improved corner brackets. Each corner bracket is made of rigid members which sandwich and securely engage corners of the flexible fabric or other material from which the sign is made. Each corner bracket provides a channel for removably holding ends of frame members which maintain the flexible message panel in message displaying configuration. The frame-receiving channels maintain the frame ends out of contact with the flexible message panel, so that the panel cannot become ripped or torn by engagement with the frame ends.
