发明名称 Rotatable, flexible flagpole arrangement
摘要 An improved rotatable flagpole arrangement for supporting a flag or banner includes an elongate pole with structure thereon for mounting a flag or banner, a lower stop surface attached to the pole and a novel bearing arrangement between the stop surface and a support surface which utilizes a pair of embossed washers. The pole may be formed of a flexible material such as PVC so that it curves away from the wind as it rotates relative to the support socket, which creates a novel, dynamic visual effect.
