An earth anchor having an elongated pointed shaft, a stop member affixed to the shaft intermediate the ends, a weighted impactor having an internal opening and being slidably received on the shaft, the impactor being engageable with the stop member by reciprocal motion to drive the shaft into the earth, the shaft having a series of spaced openings in the upper portion thereof and an elongated handle member receivable in selected openings whereby the shaft may be rotated as it is driven into the earth, the handle member being useable for impact by upward movement of the impactor to extract the anchor from the earth, and to serve as a lock to arrest the movement of the impactor when being transported.

An earth anchor comprising: an elongated shaft having a pointed lower end and having at least one opening therethrough perpendicular to the shaft longitudinal axis and in the upper portion thereof; an enlarged external diameter stop member affixed to said shaft intermediate the ends thereof and below said openings; a weighted impactor having an internal opening therethrough of a diameter greater than the external diameter of said shaft portion above said stop member, the impactor being slidably received on said shaft upper portion, the impactor having at least one external surface area in a plane of the axis of said opening therethrough which is tapered; and an elongated handle member having at least one end portion of an external diameter less than said shaft opening, the shaft being driven in the earth by the reciprocal downward impact of said impactor on said stop member and the shaft can be extricated from the earth by reciprocal impact of said impactor against said handle member positioned in said opening in said shaft, and wherein said handle member is of L-shaped configuration whereby a first portion of said handle member may be inserted into said opening in said shaft with the second portion extending generally parallel to and spaced apart from said shaft and whereby said impactor tapered surface may be forced against said handle second portion by longitudinally positioning said impactor on said shaft to restrain said impactor against further longitudinal movement.
