ABSTRACT:
A ground anchoring arrangement for attachment to, for example, the pole of a beach umbrella or the like consists of a hollow cylindrical member having a rod rotatably supported therein. A spiral screw is attached to one end of the rod, and the other end of the rod is grippingly (CANC) attachable to a handle rotator. Thus, when the handle rotator is rotated, the rod rotates, and the spiral screw rotates with it. The point of the screw is placed adjacent to the ground and rotated so that the screw digs itself into the earth to firmly fix the elongated cylinder in the ground.
