Abstract
Abstract The invention is directed to a spline structure for use with at least two wallboard structures. A vertical web is positioned between the butt edges of two wallboards and is provided with a decorative fabric coating to provide a decorative joint for the wallboard structures. Horizontal flanges from the vertical web member form fastening splines to hold the wallboard structures in position on a wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A spline structure for use with at least two wallboard structures comprising: (a) a narrow vertical web member, (b) horizontal long flanges extending perpendicularly an equal distance either side of the base of the web member, (c) horizontal short flanges extending perpendicularly an equal distance either side of the web member in the vicinity of the midpoint of the vertical web; and (d) a fabric material covering the sides and end of the narrow vertical web in the area from the short flanges to the end of the web opposite from the end of the web having the long flanges.
Claim 2
Dependent Claim
100 words
A spline structure for use with at least two wallboard structures comprising: (a) a narrow vertical web member, (b) horizontal long flanges extending perpendicularly an equal distance either side of the base of the web member, (c) horizontal short flanges extending perpendicularly an equal distance either side of the web member in the vicinity of the midpoint of the vertical web; and (d) a fabric material covering the sides and end of the narrow vertical web in the area from the short flanges to the end of the web opposite from the end of the web having the long flanges.
Claim 3
Dependent Claim
32 words
The spline structure of claim 1 wherein: (a) the portion of the vertical web covered with fabric material being enlarged with a semicircular cross-section formed at the end of the vertical web.
Claim 4
Dependent Claim
145 words
A wallboard joint structure wherein: (a) two wallboard structures with a front, back and at least one side are placed with their sides in an adjacent and slightly spaced apart relationship to form an open space joint between the wallboard sides with their backs against a structural wall, the wallboard front is covered with a fabric material, (b) a spline structure being positioned between the sides of the wallsboards to fill the space between the sides of the wallboards with only one end of the spline structure visible in the space between the wallboards; and (c) said spline structure having a semicircular cross-section formed on the visible end thereof and said semicircular cross-section being covered with a fabric material whereby, the spline structure filling the open space of the joint between two wallboards to provide the appearance of a semicircular bead between the adjacent wallboards.
Claim 5
Dependent Claim
145 words
A wallboard joint structure wherein: (a) two wallboard structures with a front, back and at least one side are placed with their sides in an adjacent and slightly spaced apart relationship to form an open space joint between the wallboard sides with their backs against a structural wall, the wallboard front is covered with a fabric material, (b) a spline structure being positioned between the sides of the wallsboards to fill the space between the sides of the wallboards with only one end of the spline structure visible in the space between the wallboards; and (c) said spline structure having a semicircular cross-section formed on the visible end thereof and said semicircular cross-section being covered with a fabric material whereby, the spline structure filling the open space of the joint between two wallboards to provide the appearance of a semicircular bead between the adjacent wallboards.
Claim 6
Dependent Claim
126 words
The wallboard joint structure of claim 3 wherein the spline structure comprises: (a) a narrow vertical web member, (b) horizontal long flanges extending perpendicularly an equal distance either side of the base of the web member with the flanges between the structural wall and back of the wallboards and means passing through the flanges fastening said flanges to the structural wall; and (c) a fabric material covering the sides and ends of the vertical web in the area from the mid-region of the web to the end of the web opposite from the end of the web having the long flanges, whereby the spline structure fills the open space of the joint between the two wallboards and does not extend over the front of the wallboards.
Claim 7
Dependent Claim
74 words
The wallboard joint structure of claim 4 wherein the spline structure comprises: (a) horizontal short flanges extending perpendicularly an equal distance either side of the web member in the vicinity of the midpoint of the vertical web, and said wallboards on their adjacent sides having grooves in the mid region of the sides and said short flanges being inserted therein whereby the spline structure holds the wallboards in position relative to the structural wall.
