Abstract
Abstract A collapsible partition assembly comprises an elongated arm which is pivoted to an elongated frame. The arm is pivotal between a storage position wherein the frame and the arm form an enclosure and a second position wherein the arm projects away from the frame to open the enclosure. A foldable partition is connected in fixed relationship with the arm and the frame so that the partition is substantially entirely enclosed in the enclosure when the arm is in a storage position. The partition expands to form a substantially rectangularly shaped panel. The partition is comprised of a plurality of flexibly connected elongated panel strips which cooperate to define a corrugated structure which is expandable and contractable relative to two generally orthogonal axes.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
167 words
A collapsible partition assembly: elongated frame means adapted to be mounted for disposition in a generally upright orientation; elongated arm means pivotally mounted at a first end thereof to said frame means, said arm means being pivotal between a first generally upright position wherein said frame means and arm means are generally parallelly oriented and cooperate to form an enclosure and a second position wherein said arm means projects away from said frame means to open the said enclosure; foldable partition means having first and second edge portions, said first edge portion being connected in fixed relationship to said frame means and said second edge portion being connected in fixed relationship to said arm means, said partition means being substantially entirely enclosable in said enclosure when said arm means is in the first position, said partition means being expandable to form a substantially rectangularly shaped panel when said arm means is in said second position; and latch means for holding said arm means in said first position.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
40 words
The collapsible partition assembly of claim 1 wherein said foldable partition means comprises a plurality of flexibly connected elongated panel strips which cooperate to define a corrugated structure which is expandable and contractable relative to two generally orthogonally disposed axes.
Claim 4
Dependent Claim
35 words
The collapsible partition assembly of claim 2 wherein said corrugated structure includes a pair of generally triangular shaped sections with the strips within the two sections respectively being oriented in a pair of transverse directions.
Claim 5
Dependent Claim
24 words
The collapsible partition assembly of claim 1 further comprising stop means to limit the pivotal movement of said arm means to said second position.
Claim 6
Dependent Claim
38 words
The collapsible partition assembly of claim 1 wherein said arm means has a pivot end and an opposing latch end and comprises a pair of side panels which are tapered from said pivot end to said latch end.
Claim 7
Dependent Claim
26 words
The collapsible partition assembly of claim 1 further comprising collapsing means for selectively pivotally moving said arm means from said second position to said first position.
Claim 8
Dependent Claim
33 words

Claim 9
Dependent Claim
21 words
The collapsible partition assembly of claim 3 wherein said partition means sections are right triangles which are interconnected at their hypotenuses.
Claim 10
Dependent Claim
53 words
The collapsible partition assembly of claim 2 wherein at least some of said panel strips have an opening and further comprising a cord extending through said opening and connecting said frame means and said arm means to yieldably resist the movement of said arm means from said first position to said second position.
Claim 11
Dependent Claim
18 words
The collapsible partition assembly of claim 1 wherein said partition means is affixed with a visual verbal message.
