Abstract
Abstract Fence post assembly including generally Y sectioned post with V sectioned anchor plate secured to post at lower end thereof. When the V sectioned anchor plate is embedded in soil, it provides greater resistance to lateral movement through soil under oblique forces applied to post than prior art flat anchor plates. V-sectioned anchor plate also tends to self-stabilize plate to align it to resist movement under oblique forces. Post has three outwards extending flanges, two of which are inclined to each other to define V therebetween. Anchor plate has two wings inclined to each other at similar V so as to fit in V of post. Post has plate location means which include notches in outer edges of the two flanges. Anchor plate has connecting means for securing anchor plate to fence post, which means include complementary pair of tangs extending from wings, the tangs engaging the notches in the flanges to sandwich the flanges between tangs and wings.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
206 words
A fence post assembly including: p1 i. an elongated, generally Y sectioned post having first, second and third flanges extending from an inner core portion of the post, the first and second flanges having outer edges and being inclined to each other at a main angle to define a V therebetween, each outer edge having two longitudinally spaced notches, ii. a V sectioned anchor plate having a longitudinal axis and first and second wings, the wings extending on generally opposite sides of the axis and being inclined to each other at an angle generally equal to the main angle of the post so as to fit in the V defined by the first and second flanges when the longitudinal axis is generally parallel to the fence post, the first and second wings each having a pair of tangs extending therefrom and spaced apart longitudinally at an axial spacing equal to axial spacing of the respective notches on the post, the tangs being adapted to engage respective notches in the outer edges of the flanges, so that the anchor plate is secured to the post by the tangs which engage the notches in the flanges and essentially prevent the plate from moving axially relative to the post.
Claim 2
Dependent Claim
206 words
A fence post assembly including: p1 i. an elongated, generally Y sectioned post having first, second and third flanges extending from an inner core portion of the post, the first and second flanges having outer edges and being inclined to each other at a main angle to define a V therebetween, each outer edge having two longitudinally spaced notches, ii. a V sectioned anchor plate having a longitudinal axis and first and second wings, the wings extending on generally opposite sides of the axis and being inclined to each other at an angle generally equal to the main angle of the post so as to fit in the V defined by the first and second flanges when the longitudinal axis is generally parallel to the fence post, the first and second wings each having a pair of tangs extending therefrom and spaced apart longitudinally at an axial spacing equal to axial spacing of the respective notches on the post, the tangs being adapted to engage respective notches in the outer edges of the flanges, so that the anchor plate is secured to the post by the tangs which engage the notches in the flanges and essentially prevent the plate from moving axially relative to the post.
Claim 3
Dependent Claim
62 words
A fence post assembly as claimed in claim 1 in which: i. each notch on the first flange is aligned transversely with a complementary notch on the second flange to form two pairs of complementary notches, ii. each tang of the first wing is aligned transversely with a respective complementary tang of the second wing to form two complementary pairs of tangs.
Claim 4
Dependent Claim
29 words
A fence post assembly as claimed in claim 2 in which: p1 i. the main angle defined by the first and second flanges of the post is approximately 120°.
Claim 5
Dependent Claim
199 words
A fence post assembly as claimed in claim 2 in which: (i). each tang has a tab portion and a step portion, the tab portion being defined by an inner edge generally adjacent the longitudinal axis of the anchor plate, and a pair of spaced side edges extending outwards from the inner edge to an outer fold; the step portion being defined by the outer fold and spaced side edges extending from the outer fold to an inner fold adjacent the wing, the step portion having a width defined by space between the inner and outer folds which width is somewhat greater than thickness of the flange of the post, the tab portion extending inwards from the step portion towards the longitudinal axis of the plate and being disposed generally parallel to the adjacent wing, and spaced from the adjacent wing a distance generally equal to the thickness of the flange, ii. the notch has a size to accept the step portion, so that when the step portion is accepted in the notch of the adjacent flange of the post, the flange is sandwiched between the tab portion and an adjacent portion of the wing of the anchor plate.
Claim 6
Dependent Claim
63 words
A fence post assembly as claimed in claim 4 in which: i. each complementary pair of tangs are sheared from the anchor plate so that a portion of the anchor plate between the tangs has an opening defined by side edges and inner folds of the tangs, the side edges of the opening being complementary to the side edges of the respective tangs.
Claim 7
Dependent Claim
41 words
A fence post assembly as claimed in claim 4 in which: i. the inner edge of each tab portion is generally parallel to the longitudinal axis of the plate and is disposed normally to the side edges of the tab portion.
Claim 8
Dependent Claim
34 words
A fence post assembly as claimed in claim 1 in which: i. the third flange of the post has a plurality of longitudinally spaced openings for retaining wire of the fence to the post.
Claim 9
Dependent Claim
50 words
A fence post assembly as claimed in claim 1 in which: i. the anchor plate has a central portion straddling the longitudinal axis of the plate, ii. the wings have upper and lower edges inclined upwardly from positions adjacent the central portion so as to provide a generally arrow-shaped plate.
Claim 10
Dependent Claim
114 words
A fence post assembly as claimed in claim 8 in which the anchor plate is characterized by: i. side edges defining in part outer portions of the wings, the side edges being parallel to the longitudinal axis of the anchor plate, ii. the central portion having upper and lower edges disposed normally to the longitudinal axis of the anchor plate and extending between plate inner corners adjacent the outer edges of the first and second flanges, iii. the upper and lower edges of the wings are inclined upwardly from the plate inner corners of the upper and lower edges respectively to intersect the side edges of the wings at approximately 45° and 135° respectively.
Claim 11
Dependent Claim
28 words
A fence post assembly as claimed in claim 1 in which; i. the main angle defined by the first and second flanges of the post is approximately 120°.
