Abstract
Abstract Anchor means for tubular posts intended to be driven into the ground comprising upper and lower anchor members. The upper anchor member comprises two interlocked components which embrace the post below the ground level and prevent it from tipping or leaning by functioning as a cantilever plate and distributing lateral stresses applied to the post over a substantially large earth area. The lower anchor member comprises a sheet metal plate having slots to receive the lower open end of the post and functions to improve the cantilever stability provided by the upper anchor member.

Claim 1
Independent Claim
219 words
Anchor means for erecting a tubular post in the ground comprising, a first component comprising a pair of vertical rectangular plates disposed substantially at 90* about a vertical corner edge, each of said plates having formed in its upper edge a vertical slot defined by adjacent marginal edge portions each formed into rigidifying ribs, a second component comprising a second pair of rectangular plates disposed substantially at 90* about a vertical corner edge and having a width substantially the same as said first pair of plates, each of the plates of said second pair having slots defined by marginal edge portions disposed similarly to the slots and marginal edge portions of the plates of said first pair with respect to the corner edge but located in the lower edges of the plates, said second component being disposed so that its plates intersect the plates of the first component with the slots of one component interengaging the slots of the other component with the rigidifying ribs of said marginal edge portions defining said interengaging slots of each component engaging in shear displacement preventing relation with the other component, and with the post being received between the corner edge portions of said components when the same are disposed below the surface of the ground, in the erected position of the post.

Claim 3
Dependent Claim
61 words
The invention as defined in claim 1 in which the terminal edge portion of each plate of one component is bent at a right angle to the plane of the plate in the direction of the other component, the marginal edge portions of each slot are formed into C ribs, and each of the plates has a vertically extending reinforcing rib.
Claim 4
Dependent Claim
61 words
The invention as defined in claim 1 including a lower anchor member disposed below said first and second components and comprising a plate having a pair of spaced slots in its upper edge, with the lower end portion of the post being received in said slots, said plate having a vertically extending reinforcing rib positioned between said pair of spaced slots.
Claim 5
Dependent Claim
29 words
The invention as defined in claim 3 in which the marginal edge portions of said slots are transversely slit to form tabs engaging opposite surfaces of the post wall.
Claim 6
Dependent Claim
17 words
The invention as defined in claim 3 in which the tabs are bent alternately in opposite directions.
Claim 7
Dependent Claim
25 words
The invention as defined in claim 3 in which the plate of the lower anchor member is provided with a plurality of vertical reinforcing ribs.
Claim 8
Dependent Claim
74 words
Anchor means for erecting a tubular post in the ground comprising a generally rectangular, substantially planar plate having a pair of spaced slots formed in its upper edge, with the lower end portion of the post being received in said slots, said plate having a vertically extending reinforcing rib positioned between said pair of spaced slots, said anchor means being disposed below the surface of the ground in the erected position of the post.
Claim 9
Dependent Claim
74 words
Anchor means for erecting a tubular post in the ground comprising a generally rectangular, substantially planar plate having a pair of spaced slots formed in its upper edge, with the lower end portion of the post being received in said slots, said plate having a vertically extending reinforcing rib positioned between said pair of spaced slots, said anchor means being disposed below the surface of the ground in the erected position of the post.
Claim 10
Dependent Claim
28 words
The inVention as defined in claim 7 in which the edge portions of said slots are transversely slit to form tabs engaging opposite surfaces of the post wall.
