Abstract: The collapsible land anchor of this invention includes an anchor body, a drive anvil coupled to the top end portion of the anchor body, and a runner member that is slidable longitudinally through the drive anvil between an operative position and a collapsed position. A retraction anvil is coupled to the top end portion of the runner member, and a hammer weight is carried on the runner member. In its operative position, the runner member extends beyond the drive anvil away from the cavity of the anchor body to space the drive anvil apart from the retraction anvil. Also in the operative position, the hammer weight is slidable along the runner member into the drive anvil to drive the anchor body into the ground. In the collapsed position, the runner member is displaced towards and at least partially stowed in the cavity of the anchor body.
