发明名称 Bird feeder support system
摘要 A bird feeder support system for suspending a bird feeder from a deck railing or like support, and of a sufficient length so as to be out of the reach of squirrels or like animals. The bird feeder support includes a U-shaped bracket for encompassing a deck railing, and upper and lower support members of which the lower member lockingly engages the U-shaped bracket at one end, and includes a hook at the end of the upper support member for engaging a bird feeder. The upper and lower support members can also be two or more components frictionally engaged with respect to each other. The lower support member can also include anti-squirrel structure, including alternating tubular members and alternating washers placed over the lower region of the lower support member so that the squirrel cannot have any footing areas or grasping areas.
