发明名称 Universal sign post base
摘要 A weighted sign post base which may be formed in various weights and has a central portion made of resilient material, such as compression molded rubber, having a universal sign post mounting hole molded into the center of the base. The universal sign post mounting hole is uniquely shaped to create a friction grip sufficient to secure the sign post to the universal sign post base upon insertion of the sign post into the universal sign post mounting hole, thereby eliminating the need of any mounting hardware and allowing speedy erection of the sign.
