ABSTRACT:
A manually installed landscape foundation (20, 56) adapted for supporting a yard light (22) or similar device requiring connection to a utility line (47) such as an electrical cable or gas line is provided having a lowermost anchor shaft (24, 64) equipped with a load-bearing helix (28, 68) and a slotted, centrally apertured (34, 62) uppermost base plate (30, 58). The anchor shaft (24, 64) is coupled with the base plate (30, 58) so as to define an open clearance area (44, 70) beneath the base plate (30, 58) and aperture (34, 62). A manual driving implement (46, 72) is used for installation purposes, and includes a T-handle (48, 74) having an engagement plate (50, 76) equipped with depending driving lugs (52, 54, 80, 82). In one foundation (20), a bail (36) defining a central clearance area (44) is used to interconnect the anchor shaft (24) and base plate (30). Alternately, in another foundation (56), the anchor shaft (64) is directly coupled in an offset relation to a base plate (58), so as to define a clearance area (70). In the latter embodiment, the driver implement (72) has the T-handle (74) thereof offset relative to the engagement plate (76), and oriented so that the T-handle (74) and anchor shaft (64) are aligned when the driver (72) is operatively coupled with the foundation (56).
