1. A ground anchor, comprising:
an anchor body having a ground insertion end and a surface end, in use the ground insertion end being inserted into a ground surface and the surface end remaining accessible from above the ground surface; one or more arms, each arm having a first end that is pivotally connected to the anchor body at a pivot point and a second end opposite the first end, the one or more arms having a ready position, a deployed position, and a retrieval position, wherein the deployed position is an intermediate pivotal position between the ready position and the retrieval position, wherein, in a direction perpendicular to the anchor body, the second end of each arm is spaced outward from the anchor body a greater distance in the deployed position that in the retrieval position; and a first actuator that releases the one or more arms to move to the retrieval position, wherein: in the ready position, an upward force applied to the anchor body causes the deployment profile to engage the ground material, the ground material causing the one or more arms to move to the deployed position in which the one or more arms extend outward from the anchor body and into the ground material; and when the first actuator is actuated, a further upward force applied to the anchor body causes the one or more arms to move to the retrieval position. |
