Abstract
Abstract A clip fastener for securing two angularly displaced abutting panels having cleats along their outer marginal surfaces including a pair of spatially displaced L-shaped wire members each having a substantially 90* angular relationship between the legs of the wire member and with the first and second wire members disposed in a nonparallel relationship to each other and with the end portions of the first and second wire members including inwardly displaced angular extensions and with at least one pair of these angular extensions interconnected for maintaining this spatial relationship between the first and second wire members. Both pairs of the angular extensions can be interconnected with at least one being a continuous interconnection and with the other having an abutting relationship. The abutting relationship may be secured using a weld joint, a crimped sleeve or any other method of maintaining the abutting members affixed to each other.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A spring wire corner fastener for securing two substantially perpendicularly displaced abutting members having cleats along the outer marginal surfaces including a pair of spatially displaced L-shaped resilient wire members, at least a substantial portion of one of the wire members substantially nonparallel to a complementary portion of the other wire member, each of the wire members including a pair of leg portions and with the leg portions of each wire member disposed substantially perpendicular to each other, a first contiguous interconnecting wire loop forming continuous extensions of first complementary end portions of the wire members and angularly displaced inwardly relative to the Lshaped resilient wire members, and a second interconnecting wire loop forming continuous extensions of second complementary end portions of the wire members and angularly displaced inwardly relative to the L-shaped resilient wire members.
Claim 2
Dependent Claim
136 words
A spring wire corner fastener for securing two substantially perpendicularly displaced abutting members having cleats along the outer marginal surfaces including a pair of spatially displaced L-shaped resilient wire members, at least a substantial portion of one of the wire members substantially nonparallel to a complementary portion of the other wire member, each of the wire members including a pair of leg portions and with the leg portions of each wire member disposed substantially perpendicular to each other, a first contiguous interconnecting wire loop forming continuous extensions of first complementary end portions of the wire members and angularly displaced inwardly relative to the Lshaped resilient wire members, and a second interconnecting wire loop forming continuous extensions of second complementary end portions of the wire members and angularly displaced inwardly relative to the L-shaped resilient wire members.
Claim 3
Dependent Claim
35 words
The spring wire corner fastener of Claim 1 wherein the complementary leg portions of the wire members extend outwardly from each other to have the wire members nonparallel to each other throughout their entire length.
Claim 4
Dependent Claim
32 words
The spring wire corner fastener of claim 2 wherein the spacing between the wire members is at its greatest at the intersection of the leg portions of the pair of wire members.
Claim 5
Dependent Claim
23 words
The spring wire corner fastener of claim 1 wherein ends of the continuous extentions forming the second interconnecting wire loop abut each other.
Claim 6
Dependent Claim
20 words
The spring wire corner fastener of claim 4 additionally including means for securing the abutting ends of the continuous extentions.
Claim 7
Dependent Claim
122 words
A clip fastener including, a first L-shpaed wire member having a substantially 90* angular relationship between the legs of the first L-shaped wire member, a second L-shaped wire member having a substantially 90* angular relationship between the legs of the second L-shaped wire member, the first and second L-shaped wire members spatially disposed relative to each other and with a substantial portion of the first L-shaped wire member in a substantially nonparallel relationship to a complementary portion of the second L-shaped wire member, and the ends of the first and second L-shaped wire members including angular extentions displaced inwardly and with at least one pair of angular extentions interconnected for maintaining the spatial relationship between the first and second L-shaped wire members.
Claim 8
Dependent Claim
122 words
A clip fastener including, a first L-shpaed wire member having a substantially 90* angular relationship between the legs of the first L-shaped wire member, a second L-shaped wire member having a substantially 90* angular relationship between the legs of the second L-shaped wire member, the first and second L-shaped wire members spatially disposed relative to each other and with a substantial portion of the first L-shaped wire member in a substantially nonparallel relationship to a complementary portion of the second L-shaped wire member, and the ends of the first and second L-shaped wire members including angular extentions displaced inwardly and with at least one pair of angular extentions interconnected for maintaining the spatial relationship between the first and second L-shaped wire members.
Claim 9
Dependent Claim
27 words
The clip fastener of claim 6 wherein the legs of the first wire member are nonparallel to the legs of the second wiRe member throughout their length.
Claim 10
Dependent Claim
18 words
The clip fastener of claim 7 wherein the first and second wire members extend outwardly from each other.
Claim 11
Dependent Claim
19 words
The clip fastener of claim 6 wherein the ends of the other pair of angular extentions abut each other.
Claim 12
Dependent Claim
18 words
The clip fastener of claim 9 additionally including means for securing the abutting ends of the angular extentions.
