Patent ID: 7987658

Claim:
A multi-purpose gardening tool, the tool comprising: (a) an elongated, hollow pole having a first end and a second end, (b) a unitary gardening head, the unitary gardening head comprising, (i) a semi-circular edger plate having a sharpened curved edge, and (ii) a comb-like rake mounted on the edger plate, the rake having a plurality of sharpened tines, (c) a coupling mechanism for pivotally connecting the second end of the elongated pole to the gardening head, the coupling mechanism releasably locking the position of the gardening head relative to the elongated pole in a variety of fixed positions to create a plurality of distinct gardening instruments, the coupling mechanism comprising, (i) a pivot screw pivotally connecting the second end of the pole to the gardening head, (ii) a lock rod extending longitudinally within the hollow pole, the lock rod having a first end and a second end, the first end being connected to a handle, and (iii) a pull cam mounted within the second end of the hollow pole, the pull cam being threadingly coupled to the second end of the lock rod wherein the pull cam includes a transverse opening that is dimensioned to receive the pivot screw, the transverse opening being partially defined by a roughened surface, (iv) wherein rotation of the lock rod longitudinally displaces the pull cam within the hollow pole, and (d) the handle rotatably mounted on the first end of the pole, the handle being fixedly connected to the coupling mechanism, wherein actuation of the coupling mechanism in order to releasably lock the position of the gardening head relative to the elongated pole is achieved through rotation of the handle.
