Abstract
A ground stake is disclosed having a plurality of blades extending outwardly from a longitudinal axis. The blades are connected along the length of the axis by at least one conical rib to promote retention of the stake within the ground.
Claims22
A stake having a top end and a bottom end and comprised of:
- a) an engaging member at the top end of the stake;
- b) a shaft, extending from the engaging member, having
- i) a longitudinal axis;
- ii) a core extending along the axis;
- iii) a plurality of blades extending outwardly from the axis, wherein each blade has two opposing planar surfaces and each planar surface directly intersects with the planar surface of an adjacent blade;
- and
- iv) at least one conical rib connecting the blades, wherein the largest radius of the conical rib is toward the top end of the stake.
