Abstract
Abstract A flexible screen closing an interior wall opening in a building, has a series of hanging columns made of adjacent tubes of flexible material, each tube having discrete pieces of solid filler material arranged in series along the length of the tube, and each tube having rings around the exterior thereof at spaced locations along the length of the tube, to constrict the tube at those locations so that the tube is sufficiently flexible to permit movement of people through the screen for passage from one room to another.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
67 words
A flexible screen comprising: a series of vertically hanging columns; each column having upper and lower end portions and comprising an elongate flexible tube containing solid filler material; said tube being constricted at vertically spaced locations intermediate said end portions thereby facilitating the flexing of the column preferentially at said locations; and each column being hung suspended from hanger means at the upper end of the tube.
Claim 2
Dependent Claim
67 words
A flexible screen comprising: a series of vertically hanging columns; each column having upper and lower end portions and comprising an elongate flexible tube containing solid filler material; said tube being constricted at vertically spaced locations intermediate said end portions thereby facilitating the flexing of the column preferentially at said locations; and each column being hung suspended from hanger means at the upper end of the tube.
Claim 3
Dependent Claim
33 words
The screen of claim 1 wherein: the filler material includes discrete pieces of material arranged in series in a line in the tube, adjacent pieces being spaced by the constrictions at said locations.
Claim 4
Dependent Claim
20 words
The screen of claim 2 wherein: the pieces have shape and composition such that they are substantially resistant to bending.
Claim 5
Dependent Claim
18 words
The screen of claim 3 wherein: the pieces are elongate and have cross-sectional dimensions snugly filling the tube.
Claim 6
Dependent Claim
16 words
The screen of claim 4 wherein: the pieces are made of a rigid plastic foam material.
Claim 7
Dependent Claim
15 words
The screen of claim 1 and further comprising: constrictors around the tubes at said locations.
Claim 8
Dependent Claim
11 words
The screen of claim 6 wherein: the constrictors are decorative rings.
Claim 9
Dependent Claim
32 words
The screen of claim 6 wherein: the filler material includes discrete pieces of material arranged in series and having shape such that each piece fills the unconstricted cross-sectional envelope of the tube.
Claim 10
Dependent Claim
25 words
The screen of claim 8 wherein: at least some of said pieces are of composition such as to be resistant to deformation of said pieces.
Claim 11
Dependent Claim
15 words
The screen of claim 9 wherein: said pieces are made of rigid plastic foam material.
Claim 12
Dependent Claim
10 words
The screen of claim 1 wherein: said tube is fabric.
Claim 13
Dependent Claim
38 words
The screen of claim 11 wherein: said tube is of circular cross section and the fabric is sewn cloth, and rings of smaller diameter than the tube are mounted on the outside of the tube at said locations.
Claim 14
Dependent Claim
73 words
A flexible screen comprising: an elongate hanger having a series of columns hanging from said hanger; said columns having upper and lower end portions and being attached to said hanger at spaced points along the length of the hanger; each column having an elongate flexible tube containing solid filler material; said tube being constricted at vertically spaced locations intermediate said end portions thereby facilitating the flexing of the column preferentially at said locations.
Claim 15
Dependent Claim
73 words
A flexible screen comprising: an elongate hanger having a series of columns hanging from said hanger; said columns having upper and lower end portions and being attached to said hanger at spaced points along the length of the hanger; each column having an elongate flexible tube containing solid filler material; said tube being constricted at vertically spaced locations intermediate said end portions thereby facilitating the flexing of the column preferentially at said locations.
Claim 16
Dependent Claim
23 words
The screen of claim 13 wherein: upper end portions of said tubes are flattened, with the flattened portions directly attached to the hanger.
Claim 17
Dependent Claim
33 words
The screen of claim 14 wherein: said flattened ends of successive columns in the series are attached to said hanger immediately adjacent the flattened ends of the next preceding columns in the series.
Claim 18
Dependent Claim
14 words
The screen of claim 15 wherein: the constrictions in adjacent tubes are staggered vertically.
Claim 19
Dependent Claim
64 words
The screen of claim 13 and further comprising: constrictors at said locations; the filler material including a piece at the bottom of the tube and having a fastener therein; a cup at the bottom of the tube and attached to said fastener, with the tube bottom being sandwiched between the bottom piece and the cup, whereby the cup protects the bottom of the tube.
Claim 20
Dependent Claim
27 words
The screen of claim 17 wherein: said cups are circular and have a diameter less than 2.5 inches, and said constrictions have diameters less than 1.75 inches.
