发明名称 Plastic barricade with handle and engagable stacking lug
摘要 A plastic barricade is formed from identical panels placed back to back and hinged together. Each panel includes a handle at the top, vertical legs with reinforcing ribs, and horizontal cross-members. The bottom most horizontal cross-member includes a stacking lug that may be inserted into the handle to prevent a stack of barricades from tipping over. The barricade may also be designed to be compatible with existing barricades.
