Abstract
Abstract A partition assembly has longitudinal and cross partition strips with interlocks for joining the longitudinal and cross strips. Each interlock has a first slot in a longitudinal strip and a second slot in a cross strip. One of the slots has a tab with the side surface of the tab adhered to a wall of the strip having the other slot. The tab is foldable generally along the line of intersection of the strips to accommodate unfolding of the partition assembly between collapsed and expanded configurations.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
134 words
A partition assembly having longitudinal and cross partition strips, interlocking means for joining said longitudinal and cross strips such that said strips cross and are interlocking and generally orthogonal in an expanded configuration, wherein said interlocking means comprises a first slot in a longitudinal strip and a second slot in a cross strip, said first and second slots being in engagement to interlock the cross strip with the longitudinal strip along a line of intersection, at least one of said strips having a tab located along the line of intersection of said strips with a side surface of said tab adhered to a side wall of the other strip, said tab being foldable generally along the line of intersection of said strips to accommodate unfolding of said partition assembly between collapsed and expanded configurations.
Claim 2
Dependent Claim
134 words
A partition assembly having longitudinal and cross partition strips, interlocking means for joining said longitudinal and cross strips such that said strips cross and are interlocking and generally orthogonal in an expanded configuration, wherein said interlocking means comprises a first slot in a longitudinal strip and a second slot in a cross strip, said first and second slots being in engagement to interlock the cross strip with the longitudinal strip along a line of intersection, at least one of said strips having a tab located along the line of intersection of said strips with a side surface of said tab adhered to a side wall of the other strip, said tab being foldable generally along the line of intersection of said strips to accommodate unfolding of said partition assembly between collapsed and expanded configurations.
Claim 3
Dependent Claim
15 words
The partition of claim 1 wherein said tab has means to facilitate the folding thereof.
Claim 4
Dependent Claim
13 words
The partition of claim 2 wherein said tab is slotted to facilitate folding.
Claim 5
Dependent Claim
13 words
The partition of claim 2 wherein said tab is perforated to facilitate folding.
Claim 6
Dependent Claim
44 words
The partition of claim 1 wherein said strip with said tab further comprises a tab-receiving opening into which said tab projects, and the slot of said strip with said tab having a slot portion extending to and opening at an edge of said strip.
Claim 7
Dependent Claim
15 words
The partition of claim 5 wherein said tab-receiving opening is separated from said slot portion.
Claim 8
Independent Claim
112 words
A method of forming a partition assembly having interlocking longitudinal and cross strips comprising the steps of: forming a longitudinal strip having a first slot therein, forming a cross strip having a second slot therein for engagement with said first slot, at least one of said strips having a tab located along the line of intersection of said strips, in any sequence, applying adhesive to one side surface of said tab, and interengaging said longitudinal and cross strips by interengagement of said slots such that said strips cross and are generally orthogonal in an expanded configuration, and adhering the adhesive side of said tab to a side wall of the other strip.
Claim 9
Independent Claim
112 words
A method of forming a partition assembly having interlocking longitudinal and cross strips comprising the steps of: forming a longitudinal strip having a first slot therein, forming a cross strip having a second slot therein for engagement with said first slot, at least one of said strips having a tab located along the line of intersection of said strips, in any sequence, applying adhesive to one side surface of said tab, and interengaging said longitudinal and cross strips by interengagement of said slots such that said strips cross and are generally orthogonal in an expanded configuration, and adhering the adhesive side of said tab to a side wall of the other strip.
Claim 10
Dependent Claim
21 words
The method of claim 7 wherein the step of applying said adhesive occurs prior to interengaging the longitudinal and cross strips.
Claim 11
Dependent Claim
28 words
The method of claim 7 further comprising folding said interengaging strips to a collapsed configuration, such that the adhesive side of said tab adheres to said side wall.
Claim 12
Dependent Claim
30 words
The method of claim 9 wherein said tab is foldable generally along the line of intersection of said strips to accommodate unfolding said partition assembly between collapsed and expanded configurations.
Claim 13
Dependent Claim
15 words
The method of claim 10 wherein said tab has means to facilitate the folding thereof.
Claim 14
Dependent Claim
45 words
The method of claim 7 wherein said strip with said tab is formed with a tab-receiving opening into which said tab projects, and the slot of said strip with said tab having a slot portion extending to and opening at an edge of said strip.
