发明名称 Self-cleaning rake
摘要 A self-cleaning rake consists of a handle, a grip, a spring release button, and two sets of tines. The handle is made from fiberglass and consists of two telescoping pieces. One of the pieces is larger in diameter and the other piece is slidably retained within it. The smaller handle piece is provided with a cleaning bar to which one set of tines are attached, and the cleaning bar further has a plurality of aligned apertures through which a second set of tines extend. The second set of tines are attached to the first handle piece, and reciprocable movement of the handle pieces relative to each other results in the cleaning bar and its attached tines moving in a manner which effects a removal of debris from both sets of tines.
