Abstract
Abstract Our all plastic insulator includes a body having means projecting forwardly therefrom for holding an electric fence wire with means at the rear thereof for resiliently gripping a Tshaped post. The post gripping means comprises a pair of resilient generally C-shaped portions extending laterally from the rear wall on the body. The rear wall is composed of two outwardly and rearwardly angling panels, a first leg section of each C-shaped portion forming a continuation of the rear wall panel to which it is connected. A wing panel projects at an angle from the free edge of a second leg section belonging to one of the C-shaped portions. The wing panel functions as a cam, enabling the installer to flex sufficiently the C-shaped portion to which it is connected to effect attachment of the insulator to a T-shaped post. The wing panel additionally serves as a handle or lever to facilitate removal of the insulator from the post should it become desirable to effect its detachment.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
167 words
A plastic fence insulator comprising a plastic body for resiliently engaging the front flanges of a T-shaped post, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic vertical wall means integrally connected to the rear of said body, a generally C-shaped plastic portion projecting laterally from each side edge of said wall means and being integral therewith, each C-shaped portion including a first leg section extending from said wall means, a bight section extending rearwardly from said first leg section and a second leg section extending forwarDly from said bight section to provide a free vertical edge, at least one of said Cshaped portions being relatively resilient, whereby hooking engagement of said one C-shaped portion with a flange on a Tshaped post can be achieved so that only the said vertical free edge of said one C-shaped portion contacts the back of said flange on the T-shaped post after the other C-shaped portion has been hooked over an opposite flange edge.
Claim 2
Dependent Claim
167 words
A plastic fence insulator comprising a plastic body for resiliently engaging the front flanges of a T-shaped post, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic vertical wall means integrally connected to the rear of said body, a generally C-shaped plastic portion projecting laterally from each side edge of said wall means and being integral therewith, each C-shaped portion including a first leg section extending from said wall means, a bight section extending rearwardly from said first leg section and a second leg section extending forwarDly from said bight section to provide a free vertical edge, at least one of said Cshaped portions being relatively resilient, whereby hooking engagement of said one C-shaped portion with a flange on a Tshaped post can be achieved so that only the said vertical free edge of said one C-shaped portion contacts the back of said flange on the T-shaped post after the other C-shaped portion has been hooked over an opposite flange edge.
Claim 3
Dependent Claim
26 words
A fence insulator in accordance with claim 1 in which said second leg sections correspond generally in length to the length of said first leg sections.
Claim 4
Dependent Claim
23 words
An electric fence insulator in accordance with claim 2 in which said second leg sections curve forwardly to provide said free vertical edges.
Claim 5
Dependent Claim
57 words
An electric fence insulator in accordance with claim 3 in which said wall means has a vertical height greater than said body and includes a pair of panels residing in planes angling outwardly and rearwardly from the horizontal center of said body, said first leg sections residing in the same general planes, respectively, as said wall panels.
Claim 6
Dependent Claim
39 words
An electric fence insulator in accordance with claim 3 in which said second leg sections provide inturned gripping edges in each instance so that both of said gripping edges contact the backs of the flanges on said T-shaped post.
Claim 7
Dependent Claim
28 words
An electric fence insulator in accordance with claim 5 including a wing panel coextensive in height with that of the second leg section of said one C-shaped portion.
Claim 8
Dependent Claim
22 words
An electric fence insulator in accordance with claim 6 in which said wing panel resides in a plane extending angularly and rearwardly.
Claim 9
Dependent Claim
36 words
An electric fence insulator in accordance with claim 7 in which said wing panel extends rearwardly at about 45* with respect to the axis at which the electric fence wire is held by said holding means.
Claim 10
Dependent Claim
134 words
An all-plastic fence insulator for use on a T-shaped post having oppositely directed front flanges comprising a plastic body, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic vertical wall means integrally connected to the rear of said body, respective plastic C-shaped hook means projecting laterally from each side edge of said wall means and being integral therewith including first leg portions integral with said body and extending laterally with respect to said wall means, curved intermediate bight portions extending rearwardly from said first leg portions and second leg portions angling forwardly from said bight portions to provide forwardly disposed free vertical edges for contacting only portions of the backs of said T-shaped post flanges which flange portions are spaced inwardly from the free edges of said flanges.
Claim 11
Dependent Claim
134 words
An all-plastic fence insulator for use on a T-shaped post having oppositely directed front flanges comprising a plastic body, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic vertical wall means integrally connected to the rear of said body, respective plastic C-shaped hook means projecting laterally from each side edge of said wall means and being integral therewith including first leg portions integral with said body and extending laterally with respect to said wall means, curved intermediate bight portions extending rearwardly from said first leg portions and second leg portions angling forwardly from said bight portions to provide forwardly disposed free vertical edges for contacting only portions of the backs of said T-shaped post flanges which flange portions are spaced inwardly from the free edges of said flanges.
Claim 12
Dependent Claim
40 words
An electric fence insulator in accordance with claim 9 in which said first leg portions angle rearwardly with respect to said body, said second leg portions angling forwardly at substantially the same angle that said first leg portions angle rearwardly.
Claim 13
Dependent Claim
140 words
In combination with a T-shaped post having laterally extending front flanges and a central flange or web extending rearwardly from the juncture of said front flanges, a plastic fence insulator comprising a plastic body, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic wall means integrally connected to the rear of said body, a pair of generally C-shaped plastic hooks projecting laterally from each side of said wall means, each hook including a first leg section angling rearwardly so as to engage the forward corner of said flanges, a bight section curving rearwardly from said first leg section and a second leg section extending forwardly from said bight section to provide a forwardly disposed free edge engaging the backs of said flanges only at locations spaced inwardly from the rear corners of said flanges.
Claim 14
Dependent Claim
140 words
In combination with a T-shaped post having laterally extending front flanges and a central flange or web extending rearwardly from the juncture of said front flanges, a plastic fence insulator comprising a plastic body, means projecting forwardly from said body for holding an electric fence wire, relatively rigid plastic wall means integrally connected to the rear of said body, a pair of generally C-shaped plastic hooks projecting laterally from each side of said wall means, each hook including a first leg section angling rearwardly so as to engage the forward corner of said flanges, a bight section curving rearwardly from said first leg section and a second leg section extending forwardly from said bight section to provide a forwardly disposed free edge engaging the backs of said flanges only at locations spaced inwardly from the rear corners of said flanges.
