Abstract:
1. A manually operated adjustable earth moving tool, comprising: an elongated substantially solid bar having a central longitudinal axis, a first end, a second end, and an intervening portion located between said first end and said second end, said intervening portion having a length and a bar cross-sectional geometry, wherein said length of said intervening portion has a plurality of height adjustment bolt-holes linearly disposed along said length of said intervening portion of said elongated substantially solid bar wherein said plurality of bolt-holes have substantially identical dimensions and orientations with respect to said central longitudinal axis, at least one of said first end or said second end having a configured tip that provides a means for affecting soil, a handle assembly comprising a tubular receiver having an inner portion, an outer portion, and two coaxially aligned opposing handles, wherein said two coaxially aligned opposing handles each have an outer end and are both symmetrically disposed about said outer portion of said tubular receiver, and said inner portion has a receiver cross-sectional geometry substantially similar to said bar cross-sectional geometry such that a sliding engagement between said elongated substantially solid bar and said handle assembly is enabled, wherein a portion of said bar cross-sectional geometry and said receiver cross-sectional geometry having a substantially similar non-circular cross-sectional geometry such that said elongated substantially solid bar and said handle assembly are substantially coupled to each other wherein rotational motion about said central longitudinal axis with respect to one another is inhibited while permitting said sliding engagement between said elongated substantially solid bar and said handle assembly, a means for slidably affixing said handle assembly to any of said plurality of bolt-holes disposed along said length of said intervening portion, thereby providing a means for adjusting said handle assembly along said elongated substantially solid bar, wherein said means for slidably affixing said handle assembly further comprises one of said opposing handles of said handle assembly, having an outer end, further comprises an integrated self-actuating locking pin feature having a locked and an unlocked position, said integrated locking pin self-closing feature comprising:
