发明名称 Hand operated traffic signal device
摘要 A hand-held ground-supported display device for warning passersby is disclosed. Included is a self-supporting sign panel and a plurality of at least three mast sections telescopically interfittable, one within the other. A coupler is attached to the sign panel, with a socket for releasably engaging the top mast section. The mast sections have progressively smaller internal diameters and progressively shorter lengths, with the outermost mast section having the largest internal diameter and the longest length. Middle mast upper and middle mast lower stop members are attached to upper and lower ends of the middle mast section, respectively. In one example, the middle mast upper stop member has an end wall with first and second sidewalls extending downwardly therefrom with lower free ends for interfering with stop members associated with the top and the bottom mast sections. A kit including the display device is also disclosed.
