Abstract

Abstract The invention involves a structural interlocking joint system for structural panels used in building construction. A skeleton is formed of interlocking ribs which engage panel skins which are grooved in a pattern to receive the edges of the interlocked ribs. The grooves of each panel skin are formed with their edges angled away from the groove to provide both a wider opening for insertion of the rib skeleton into the grooves, and to provide, after such joining insertion, a reservoir for any excess glue forced out by the joining process. Along the longitudinal edges of the ribs is formed a uniform channel which provides a defined reservoir for glue of substantially even width and depth between the edge of each rib and the bottom of the corresponding groove within the skin. Thus, in the insertion of a rib within a groove, the glue is directed into a substantially uniform strip within the rib edge channel, maximizing strength and minimizing localized glue overflow. Any overflow which occurs from the rib edge channel is contained by the reservoir formed by the angle-edge grooves in the skin.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 225 words
A structural interlocking joint system, for structural panels used in building construction, comprising: a. at least one first rib having a first longitudinal edge and an opposing second longitudinal edge; b. at least one second rib having a first longitudinal edge and an opposing second longitudinal edge; c. means for interconnection of said first rib and said second rib to form a skeleton for a structural panel so that said first longitudinal edge of said first rib and said first longitudinal edge of said second rib substantially lie in a first plane and said second longitudinal edge of said first rib and said second longitudinal edge of said second rib substantially lie in a second plane; d. a least one panel skin which is formed with elongated grooves so as to receive said first longitudinal edges of said first rib and said second rib; e. said first longitudinal edges of said first and second ribs engaging said panel skin within said grooves formed in said panel skin; f. each of said panel skin-engaging longitudinal edges of said first and second ribs having a longitudinal channel formed therein, said channel being of substantially uniform width and depth so as to form a reservoir to provide uniform distribution and minimize overflow of glue between said edge of said rib and said groove formed within the panel skin.
Claim 2
Dependent Claim 225 words
A structural interlocking joint system, for structural panels used in building construction, comprising: a. at least one first rib having a first longitudinal edge and an opposing second longitudinal edge; b. at least one second rib having a first longitudinal edge and an opposing second longitudinal edge; c. means for interconnection of said first rib and said second rib to form a skeleton for a structural panel so that said first longitudinal edge of said first rib and said first longitudinal edge of said second rib substantially lie in a first plane and said second longitudinal edge of said first rib and said second longitudinal edge of said second rib substantially lie in a second plane; d. a least one panel skin which is formed with elongated grooves so as to receive said first longitudinal edges of said first rib and said second rib; e. said first longitudinal edges of said first and second ribs engaging said panel skin within said grooves formed in said panel skin; f. each of said panel skin-engaging longitudinal edges of said first and second ribs having a longitudinal channel formed therein, said channel being of substantially uniform width and depth so as to form a reservoir to provide uniform distribution and minimize overflow of glue between said edge of said rib and said groove formed within the panel skin.
Claim 3
Dependent Claim 103 words
The structural interlocking joint system, for structural panels used in building construction, as recited in claim 1, wherein, additionally, each said elongated groove of said panel skin having a bottom and two sides, said sides of said groove having their outer edges angled so as to form an open space which provides, between said ribs and said elongated grooves, an additional reservoir for any glue which is forced out of the elongated groove by the insertion of said edge of said rib into said elongated groove, and also provides a wider opening to said groove for insertion of said first and second ribs.
Claim 4
Dependent Claim 28 words
The structural interlocking joint system, for structural panels used in building construction, as recited in claim 1, wherein said first rib and said second rib are oriented orthoganally.
Claim 5
Dependent Claim 41 words
The structural interlocking joint system, for structural panels used in building construction, as recited in claim 1, where there are a plurality of said first ribs and said second ribs, said first ribs being parallel and said second ribs being parallel.
Claim 6
Dependent Claim 68 words
The structural interlocking joint system, for structural panels used in building construction, as recited in claim 1, wherein the means for interconnection of said first and second ribs to form said skeleton includes elongated notches formed in said first ribs and second ribs, said notches having a depth so that when said notches of said first rib and said second rib mutually fully engage, said skeleton is formed.
Claim 7
Dependent Claim 329 words
A structural interlocking joint system, for structural panels used in building construction, comprising: a. at least one first rib having a first longitudinal edge and an opposing second longitudinal edge; b. at least one second rib having a first longitudinal edge and an opposing second longitudinal edge; c. means for interconnection of said first rib and said second rib to form a skeleton for a structural panel so that said first longitudinal edge of said first rib and said first longitudinal edge of said second rib substantially lie in a first plane and said second longitudinal edge of said first rib and said second edge of said second rib substantially lie in a second plane; d. at least one panel skin which is formed with elongated grooves so as to receive said first longitudinal edges of said first rib and said second rib; each said elongated groove in said panel skin having a bottom and two sides; e. said longitudinal edges of said first and second ribs engaging said panel skin within said grooves formed in said panel skin; f. each of said panel skin engaging longitudinal edges of said first and second ribs having a longitudinal channel formed therein, said channel being of substantially uniform width and depth and extending the full length of said longitudinal edge of said rib, so as to form a reservoir to provide uniform distribution and minimize overflow for glue between said edge of the rib and the bottom of the groove formed within the panel skin. g. said sides of said groove of said panel skin having their outer edges angled so as to form an open space which provides, between said ribs and said elongated grooves, an additional reservoir for any glue which is forced out of the elongated groove by the insertion of said edge of said rib into said elongated groove, and also which provides a wider opening to said groove for insertion of said first and second ribs;
