Abstract
Abstract A ground anchor for posts, poles and the like having a base plate assembly accommodating pitch or tilt adjustment of the pole or post relative to the anchor and adapted to yield and break away when the pole or post is subjected to a lateral impact force of a predetermined magnitude. The anchor has a pile member driven into the ground carrying tentacles which are ejected to form anchoring roots. A base plate at the upper end of the pile member compacts the underlying earth and rigid vanes underlying the base plate stiffen the assembly and may be helically shaped to provide a screw thread locking relationship with the earth. A post base plate is adjustably anchored to the pile base plate with fasteners that can yield or break when the post is struck by a vehicle. The post may be attached to the pile member by spring means permitting the post to deflect under impact and then retracting the post to an upright position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
A ground anchor for posts and the like which comprises a pile member adapted to be driven in the ground, a base plate secured on the pile member adjacent the upper end thereof and extending laterally therefrom, tentacle rods deflectable from said pile member below the base plate to form anchoring roots for the pile member, a post, a post mounting plate secured to the bottom of the post and extending laterally therefrom, said mounting plate overlying the base plate of the pile member and tiltably supported on the upper end of the pile member, tubes depending from the base plate of the pile member having bending orifices, and rods extending from said post mounting plate through said tubes adapted to be deformed by said bending orifices to provide adjustable fasteners locking the post mounting plate to the base plate on the pile member thereby controlling the tilt or pitch of the post on the post plate.
Claim 2
Dependent Claim
157 words
A ground anchor for posts and the like which comprises a pile member adapted to be driven in the ground, a base plate secured on the pile member adjacent the upper end thereof and extending laterally therefrom, tentacle rods deflectable from said pile member below the base plate to form anchoring roots for the pile member, a post, a post mounting plate secured to the bottom of the post and extending laterally therefrom, said mounting plate overlying the base plate of the pile member and tiltably supported on the upper end of the pile member, tubes depending from the base plate of the pile member having bending orifices, and rods extending from said post mounting plate through said tubes adapted to be deformed by said bending orifices to provide adjustable fasteners locking the post mounting plate to the base plate on the pile member thereby controlling the tilt or pitch of the post on the post plate.
Claim 3
Dependent Claim
33 words
The ground anchor of claim 1 wherein the rods have heads engageable with the post mounting plate and nail-like tentacles extending through the tubes depending from the base plate of the pile member.
Claim 4
Dependent Claim
177 words
An adjustable break-away mounting for ground anchors having a pile member driven into the ground and a radial base plate secured on the upper end of the pile member which comprises a post having attached to the bottom thereof a radial post plate overlying thE base plate of the pile member in spaced relation, said post plate having a rounded projection tiltably engaging the upper end of the pile member, a plurality of adjustable fasteners surrounding the post radially outward from the post and pile member connecting the post plate with the base plate to control the tilt of the post plate relative to the ground anchor, and said fasteners having a predetermined limited load carrying capacity permitting the post plate to break away from the base plate upon application of excessive side impact loads. 4 The breakaway mounting of claim 3 wherein the post is attached to the post plate by a spring permitting the post to tilt relative to the pile member under excessive impact loads and retracing the post upon release of said load.
Claim 5
Dependent Claim
18 words
The anchor of claim 4 wherein the post is hollow and the spring is inside the hollow post.
Claim 6
Dependent Claim
27 words
The mounting of claim 3 wherein a spring connects the post plate to the post and a plate affixed to the post rests on the post plate.
Claim 7
Dependent Claim
152 words
An adjustable breakaway mounting for ground anchors of the type having a pile member for driving in the ground and a base plate radiating from the upper portion of the pile member adapted to compact earth surrounding the pile member, a post supported on the pile member, a radial post plate secured to the bottom of the post, said post plate overlying said base plate in spaced relation, nail-like fasteners extending from the post plate through the base plate in spaced relation from the pile member and from each other, and means on the base plate deforming said fasteners to unite the post plate with the base plate at the desired angular relationship to control the post position and adapted to be straightened out to accommodate separation of the post from the pile member while resisting said separation to prevent the post from flying into the air upon receiving an impact blow.
Claim 8
Dependent Claim
152 words
An adjustable breakaway mounting for ground anchors of the type having a pile member for driving in the ground and a base plate radiating from the upper portion of the pile member adapted to compact earth surrounding the pile member, a post supported on the pile member, a radial post plate secured to the bottom of the post, said post plate overlying said base plate in spaced relation, nail-like fasteners extending from the post plate through the base plate in spaced relation from the pile member and from each other, and means on the base plate deforming said fasteners to unite the post plate with the base plate at the desired angular relationship to control the post position and adapted to be straightened out to accommodate separation of the post from the pile member while resisting said separation to prevent the post from flying into the air upon receiving an impact blow.
Claim 9
Dependent Claim
164 words
A ground anchor for posts and the like which comprises a tube adapted to be driven into the ground and having an open top mouth, a base plate surrounding and secured to the tube and extending laterally therefrom to compact the earth underlying the plate around the tube when the tube is driven into the ground, a post plate having a rounded projection on the central portion thereof seated in the open mouth of the anchor tube and supporting the plate from the tube in spaced relation from the base plate, fasteners extending between the base plate and post plate in spaced relation from the tube and from each other for clamping the rounded projection of the post plate in the mouth of the tube, and means for adjusting the fasteners to vary the spacing of portions of the post plate relative to the base plate to thereby control the inclination of the post plate and a post mounted thereon relative to the tube.
Claim 10
Dependent Claim
164 words
A ground anchor for posts and the like which comprises a tube adapted to be driven into the ground and having an open top mouth, a base plate surrounding and secured to the tube and extending laterally therefrom to compact the earth underlying the plate around the tube when the tube is driven into the ground, a post plate having a rounded projection on the central portion thereof seated in the open mouth of the anchor tube and supporting the plate from the tube in spaced relation from the base plate, fasteners extending between the base plate and post plate in spaced relation from the tube and from each other for clamping the rounded projection of the post plate in the mouth of the tube, and means for adjusting the fasteners to vary the spacing of portions of the post plate relative to the base plate to thereby control the inclination of the post plate and a post mounted thereon relative to the tube.
Claim 11
Dependent Claim
42 words
The anchor of claim 8 wherein the rounded projection on the post plate and the open top mouth of the tube provide cooperating ball and socket components with the ball on the post plate tiltably seated in the socket of the tube.
