  • Publication number: 20150257335
    Abstract: Disclosed is a self-cleaning rake. The rake includes an elongated shaft having a rake head on one end thereof. The rake head includes a plurality of elongated tines that can be used to rake leaves and other debris. A cleaning bar is slidably disposed on the tines and can be moved from the first end of the tines towards the second end in order to remove debris lodged between the tines. An extension rod is secured at a first end to the cleaning bar and extends through the rake head and into the interior of the elongated shaft of the self-cleaning rake. A grip is slidably positioned on the exterior of the shaft and is operably connected to the extension rod, such that moving the grip moves the cleaning bar along the tines. The extension rod may be spring-loaded so that the extension rod automatically retracts when extended.
