发明名称 Ground anchor stake device
摘要 A ground anchor stake device characterized by a novel combination of ground-penetrating angular spike means and ground-penetrating arcuate tine means. The spike means and the tine means are movably interconnected in such manner that the spike means may be first pushed into the ground at an acute angle to the ground surface, and the arcuate tine means then pushed into the ground in a circular arcuate path to the ground surface. The ends of the spike means and the ends of the tine means, being inserted into the ground from opposite direction toward each other, encompass a mass of ground between them to securely anchor the stake device in the ground. Removal of the device from the ground is by first lifting the arcuate tine means from the ground and then lifting the angular spike means from the ground.
