Abstract
Abstract An edge connector for connecting structural members at their adjacent edges is disclosed, including a base extending transversely between its edges, a support wall integral with the base and extending away from the base on one side thereof, the support wall extending generally parallel to the base edges and being positioned between the transverse center of the base and one edge; and a tongue integrally connected at one end to the support wall, extending from the support wall to a free end thereof; and spaced away from the base and positioned between the transverse center of the base and the other edge of the base on the side of the center opposite the one base edge, the tongue and the base defining a recess therebetween to receive the tongue of a mating connector.

An edge connector for connecting structural members at their adjacent edges, comprising: a base extending transversely between edges of said base; a support wall integral with said base extending away from said base on one side thereof, said support wall extending generally parallel to said base edges and being positioned between the transverse center of said base and one edge of said base; a detent or groove in said one side of said base positioned between said transverse center of said base and said other edge of said base; and a tongue integrally connected at one end to said support wall and extending from said support wall to a free end thereof spaced away from said base and positioned between the transverse center of said base and the other edge of said base, said tongue and said base defining a recess therebetween to receive a tongue of a mating connector.
Claim 2
Dependent Claim
150 words
An edge connector for connecting structural members at their adjacent edges, comprising: a base extending transversely between edges of said base; a support wall integral with said base extending away from said base on one side thereof, said support wall extending generally parallel to said base edges and being positioned between the transverse center of said base and one edge of said base; a detent or groove in said one side of said base positioned between said transverse center of said base and said other edge of said base; and a tongue integrally connected at one end to said support wall and extending from said support wall to a free end thereof spaced away from said base and positioned between the transverse center of said base and the other edge of said base, said tongue and said base defining a recess therebetween to receive a tongue of a mating connector.
Claim 3
Dependent Claim
56 words
The edge connector of claim 1 wherein the end of said support wall spaced from said base and the side of said tongue opposite said recess define an outer surface comprising a protrusion extending from said outer surface away from said recess between said transverse center of said base and said one edge of said base.
Claim 4
Dependent Claim
18 words
The edge connector of claim 2 wherein said protrusion is located at the end of said support wall.
Claim 5
Dependent Claim
30 words
The edge connector of claims 1, 2 or 3 wherein said detent or groove is located between said free end of said tongue and said other edge of said base.
Claim 6
Dependent Claim
38 words
The edge connector of claim 1 wherein said tongue, in section, has parallel walls extending parallel to said base, said tongue spaced from said base a distance sufficient to receive a similarly dimensioned tongue of said mating connector.
Claim 7
Dependent Claim
32 words
The edge connector of claim 1 wherein said base further comprises at least one leg integral with and extending away from said base on the other side thereof opposite said support wall.
Claim 8
Dependent Claim
33 words
The edge connector of claim 6 wherein said base further comprises at least two said legs integral with and extending away from said base on the other side thereof opposite said support wall.
Claim 9
Dependent Claim
36 words
The edge connector of claim 7 wherein said base further comprises a crossbar between two said legs, said crossbar being spaced from said base and creating a channel between said legs, said base and said crossbar.
Claim 10
Dependent Claim
18 words
The edge connector of claim 8 wherein said two legs extend away from said base beyond said crossbar.
Claim 11
Dependent Claim
27 words
