ABSTRACT:
A hand held garden implement, namely a rake, which allows for self-cleaning through the new design of the rakes prongs or teeth of collected leaves, grass, vegetable matter or other adhering material. The head of the rake, containing a plurality of interconnected prongs or teeth, moves as a unit. The first prong or tooth has a first leg that extends from a first tine, and a second leg that extends from a second, adjacent tine. The two legs meet and are joined at a rounded point midway between the two tines and forms a triangular shape. The next prong or tooth has a first leg that extends from the second tine and meets a second leg extending from a third adjacent tine. Each prong or tooth is substantially perpendicular to the tines. Between each prong or tooth, at the point where each leg meets a tine is a 2-2.5 inch slot cut vertically up each tine to allow each prong or tooth the ability to work independently of each other. This order of the first two prongs or teeth continue until the desired rake width is met. The existence of the prongs or teeth between the tines will enable the rake head to remain clear of debris without any additional movements by the operator.
