ABSTRACT:
A ground engaging stake used to anchor and support equipment with respect to the soil includes an I-beam and a spring assembly which engages the I-beam. The I-beam includes a web plate and a pair of end plates which extend perpendicularly to the web plate at opposite edges thereof. A pair of guide plates are spaced from and parallel to a middle portion of the web plate. A pair of cams are mounted on each side of the web plate adjacent a bottom end thereof. The spring assembly includes a pair of spaced parallel springs rigidly attached to one another at a top thereof by a center stop. A pair of side stop blocks are attached to the top outer surface of each spring. Springs 32 extend between a slot formed between the guide plates and web plate of the I-beam. The spring is driven downwardly causing the springs to deflect against an angled top surface of each cam and bend slightly outwardly away from the I-beam. The lateral projection of each spring creates a resistance against the soil to retain the ground stake in a stationary position with respect to the soil.
