发明名称 Stabilized A-frame sign stand
摘要 An improved A-frame sign stand is disclosed. The sign stand includes front and rear panels hingedly attached. A support rod is removably attachable to the panels and prevents both separation and buckling of the panels. The support rod can be placed into various storage positions. In one such position, the rod may be used as a handle. In another embodiment, the rod can be pivoted upward and stored on an inner surface of the panel.
