Abstract

Abstract There is described electrical fencing comprising a plurality of upright elongate fence posts, each fence post comprising an upright rigid metallic-rod adapted to be embedded into the earth, said metallic-rod carrying an uprightly extending resinous electrically-insulative resinous sheath disposed at an elevation common to the fencing current-carrying conductor wire(s). Although the conductor wire might be tied directly to the fence post external resinous sheath, preferably an intervening C-shaped wire-connector member is utilized which is removably frictionally engaged at a selectable continuum of elevations along the fence post sheath. The lower portion of the fence post might include an angular anchor-plate admirably suited to maintain the fence post perpendicular to the earth''s surface.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 204 words
A vertically uprightable fence construction wherein a plurality of fence posts embedded into the earth together with wire-connector members are adapted to maintain at least one current-carrying conductor wire in substantial parallelism with the earth''s surface, said electrical fence construction comprising: A. An elongate rigid metallic-rod having a lofty height extending along an upright vertical-axis whereby said metallicrod has an upper-end and a lower-end, said metallic-rod having sufficient rigidity and compressive strength that the lower-end thereof might be embedded downwardly below the earth''s surface through compressive forces exerted along the metallic-rod vertical-axis, an upright finite-length of said metallic-rod having a regular transverse cross-sectional size and shape; B. An electrically insulative uprightly extending sheath completely surrounding and affirmatively attached along the rigid metallic-rod upright finite-length, said sheath being chemically homogeneous and comprising at least one-half by weight a structurally continuous hydrophobic resinous material; and C. A wire-connector member removably attached to the resinous sheathed portion of the metallic-rod, said wire-connector member including a resiliently expandable horizontal C-shaped resinous insulator portion surrounding and frictionally engaged with the metallic-rod resinous sheathed portion, said wireconnector including a resiliently expandable C-shaped metallic component that is radially spaced from the frictional contact between the wire-connector and the metallic-rod resinous sheath.
Claim 2
Dependent Claim 204 words
A vertically uprightable fence construction wherein a plurality of fence posts embedded into the earth together with wire-connector members are adapted to maintain at least one current-carrying conductor wire in substantial parallelism with the earth''s surface, said electrical fence construction comprising: A. An elongate rigid metallic-rod having a lofty height extending along an upright vertical-axis whereby said metallicrod has an upper-end and a lower-end, said metallic-rod having sufficient rigidity and compressive strength that the lower-end thereof might be embedded downwardly below the earth''s surface through compressive forces exerted along the metallic-rod vertical-axis, an upright finite-length of said metallic-rod having a regular transverse cross-sectional size and shape; B. An electrically insulative uprightly extending sheath completely surrounding and affirmatively attached along the rigid metallic-rod upright finite-length, said sheath being chemically homogeneous and comprising at least one-half by weight a structurally continuous hydrophobic resinous material; and C. A wire-connector member removably attached to the resinous sheathed portion of the metallic-rod, said wire-connector member including a resiliently expandable horizontal C-shaped resinous insulator portion surrounding and frictionally engaged with the metallic-rod resinous sheathed portion, said wireconnector including a resiliently expandable C-shaped metallic component that is radially spaced from the frictional contact between the wire-connector and the metallic-rod resinous sheath.
Claim 3
Dependent Claim 20 words
The electrical fence post of claim 1 wherein the sheath resinous material comprises a thermoplastic polymer of cellulose acetate butyrate.
Claim 4
Dependent Claim 53 words
The electrical fence post of claim 1 wherein the resinous insulator component of the wire-connector member includes at least one vertical drainage hole therethrough and also includes a pair of oppositely extending resinous tabs which are uprightly coparallel, said two tabs being adapted to removably engage thereBetween a generally horizontal current-carrying conductor wire.
