Abstract
Abstract A connector for affixing the top rail of a wire fabric fence to the fence posts thereof is described. The connector consists of a resilient metallic strip fabricated into a loop portion from which depend leg portions which extend inward, substantially parallel, then outward. When inserted into a fence post the connector legs enter into yielding frictional engagement with the inner walls thereof, said engagement being enhanced by the engagement of said parallel portions with one another thereby increasing the resiliency of the connector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A resilient connector for attaching a hollow first longitudinal member to a transverse longitudinal member, said connector comprising: (a) a loop portion for receiving said transverse longitudinal member; and, (b) leg portions extending from said loop portion for insertion into one end of said first longitudinal member and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (i) a first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (ii) a substantially parallel portion, said parallel portions of each leg being configured to engage one another when said legs are inserted into said first longitudinal member whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said first longitudinal member.
Claim 2
Dependent Claim
137 words
A resilient connector for attaching a hollow first longitudinal member to a transverse longitudinal member, said connector comprising: (a) a loop portion for receiving said transverse longitudinal member; and, (b) leg portions extending from said loop portion for insertion into one end of said first longitudinal member and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (i) a first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (ii) a substantially parallel portion, said parallel portions of each leg being configured to engage one another when said legs are inserted into said first longitudinal member whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said first longitudinal member.
Claim 3
Dependent Claim
47 words
The connector of claim 1 in which each leg further comprises a second inclined portion extending inclinedly outward from said substantially parallel portion, the end of each said second inclined portion being effective to frictionally engage the inner walls of said first longitudinal member when inserted therein.
Claim 4
Dependent Claim
17 words
The connector of claim 2 in which said connector is formed from flat, elongated resilient metal strip.
Claim 5
Dependent Claim
135 words
A resilient connector for attaching a rail to the top of a hollow, substantially rectangular section fence post, said connector comprising: (a) a loop portion for receiving said rail; and, (b) leg portions extending from said loop portion for insertion into the top of said fence post and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (i) a first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (ii) a substantially parallel portion, said parallel portions of each leg being configured to engage one another when said legs are inserted into said fence post whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said fence post.
Claim 6
Dependent Claim
135 words
A resilient connector for attaching a rail to the top of a hollow, substantially rectangular section fence post, said connector comprising: (a) a loop portion for receiving said rail; and, (b) leg portions extending from said loop portion for insertion into the top of said fence post and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (i) a first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (ii) a substantially parallel portion, said parallel portions of each leg being configured to engage one another when said legs are inserted into said fence post whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said fence post.
Claim 7
Dependent Claim
46 words
The connector of claim 4 in which each leg further comprises a second inclined portion extending inclinedly outward from said substantially parallel portion, the end of each said second inclined portion being effective to frictionally engage the inner walls of said fence post when inserted therein.
Claim 8
Dependent Claim
17 words
The connector of claim 5 in which said connector is formed from flat, elongated, resilient metal strip.
Claim 9
Dependent Claim
135 words
A fence support system, comprising: (a) a hollow, substantially rectangular section fence post; (b) a rail; and, (c) a connector means for attaching said rail to said fence post, said connector comprising (i) a loop portion for receiving said rail; and, (ii) leg portions extending from said loop portion for insertion into the top of said rail and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (aa) first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (bb) a substantially parallel portion, said parallel portions of said legs being configured to engage one another whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said fence post.
Claim 10
Dependent Claim
135 words
A fence support system, comprising: (a) a hollow, substantially rectangular section fence post; (b) a rail; and, (c) a connector means for attaching said rail to said fence post, said connector comprising (i) a loop portion for receiving said rail; and, (ii) leg portions extending from said loop portion for insertion into the top of said rail and into yielding frictional engagement with the inner walls thereof, each of said legs further comprising (aa) first inclined portion in which said legs extend inclinedly inward toward the axis of said connector; and, (bb) a substantially parallel portion, said parallel portions of said legs being configured to engage one another whereby the mutual engagement of said parallel portions enhances the resiliency of said legs and the frictional engagement thereof with the inner walls of said fence post.
Claim 11
Dependent Claim
48 words
The fence support system of claim 7 in which each leg further comprises a second inclined portion extending inclinedly outward from said substantially parallel portion, the end of each said second inclined portion being effective to frictionally engage the inner walls of said fence post when inserted therein.
Claim 12
Dependent Claim
19 words
The fence support system of claim 8 in which said connector is formed from flat, elongated, resilient metal strip.
