Abstract

Abstract A portable and foldable wall partition is provided which includes a plurality of spaced-apart, slidable and heightwise adjustable upstanding vertical supports and a plurality of horizontally-extending lateral supports, each of which is pivotably supported at its ends between a pair of adjacent vertical supports to permit a width adjustment of the wall partition. A filler material is wound on the lateral supports and is unwound therefrom to serve as wall panels for the wall partition. The wall partition has an extremely light weight and high degree of stability. It easily accommodates a wide range of room dimensions while affording a highly effective seal with the floor, ceiling, and walls of the room in which it is installed.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 242 words
A portable and foldable wall partition, comprising: a plurality of upstanding spaced-apart vertical supports, each of which has at least one roller coupled to the lower end thereof to permit rolling of the supports along a floor; a plurality of sheaths each of which encompass the lower end portion of one of said vertical supports and which is axially adjustable relative to the vertical support on which it is mounted, said sheath including a generally, bell-shaped jacket which encloses said roller and which is engageable with the floor; a plurality of horizontally-extending lateral supports, each of which extends between a pair of adjacent vertical supports, said lateral supports being supported at their ends on said vertical supports for limited pivotable movement about a vertical axis so as to maintain a minimum angle which is greater than zero between two adjacent lateral supports and to ensure the stability of the wall partition, said lateral supports being rotatable about their longitudinal axes and being arrestable in a fixed position; a filler material which is at least partially woundable on said lateral supports, the lower end of which serves as a seal for sealing engagement with the floor; a plurality of top sealing members, each of which is coupled to one of said lateral supports for sealing the wall partition against a ceiling; and a plurality of flexible joint covering bars for sealing the spaced between the two outermost vertical supports and adjacent room walls.
Claim 2
Dependent Claim 242 words
A portable and foldable wall partition, comprising: a plurality of upstanding spaced-apart vertical supports, each of which has at least one roller coupled to the lower end thereof to permit rolling of the supports along a floor; a plurality of sheaths each of which encompass the lower end portion of one of said vertical supports and which is axially adjustable relative to the vertical support on which it is mounted, said sheath including a generally, bell-shaped jacket which encloses said roller and which is engageable with the floor; a plurality of horizontally-extending lateral supports, each of which extends between a pair of adjacent vertical supports, said lateral supports being supported at their ends on said vertical supports for limited pivotable movement about a vertical axis so as to maintain a minimum angle which is greater than zero between two adjacent lateral supports and to ensure the stability of the wall partition, said lateral supports being rotatable about their longitudinal axes and being arrestable in a fixed position; a filler material which is at least partially woundable on said lateral supports, the lower end of which serves as a seal for sealing engagement with the floor; a plurality of top sealing members, each of which is coupled to one of said lateral supports for sealing the wall partition against a ceiling; and a plurality of flexible joint covering bars for sealing the spaced between the two outermost vertical supports and adjacent room walls.
Claim 3
Dependent Claim 89 words
The wall partition according to claim 1, wherein said bell-shaped jackets of said sheaths which encompass the vertical supports disposed between the two outermost vertical supports have an equilateral triangular configuration, and said vertical supports extend upwardly from the center of the triangular-shaped jackets and wherein three of said rollers are coupled to each of said vertical supports and are each cylindrically shaped, said rollers coupled to each of said supports being positioned such that their axes are parallel to the sides of the triangular-shaped jacket of said sheaths.
Claim 4
Dependent Claim 49 words
The wall partition according to claim 1, wherein said bell-shaped jackets of said sheaths which encompass said outermost vertical supports have a right triangular configuration and said outermost vertical supports extend upwardly from the corner area which forms the apex of the right angle of said right triangular-shaped jackets.
Claim 5
Dependent Claim 72 words
The wall partition according to claim 1, additionally including a plurality of freely-rotatable support members, each of which is supported on the upper end of one of said vertical supports in an incremental and axially adjustable manner relative to said vertical supports, and which support said lateral supports, and wherein said vertical supports and said sheaths are threadably secured together to permit axial adjustment of said vertical supports relative to said sheaths.
Claim 6
Dependent Claim 89 words
The wall partition according to claim 1, additionally including a plurality of auxiliary, horizontally-extending, lateral supports each of which extends between a pair of adjacent vertical supports and is disposed parallel and adjacent to said lateral support of said first mentioned plurality, said auxiliary lateral supports being rotatable about their longitudinal axes and being arrestable in a fixed position, said partition also including secondary filler material which is wound on each of said auxiliary lateral supports in an opposite direction to said filler material wound on said lateral supports.
Claim 7
Dependent Claim 70 words
The wall partition according to claim 1, wherein said filler material comprises a unitary web of material which extends across the total width of the wall partition, said filler material having a plurality of vertically-extending slots formed in the upper end thereof spaced apart a distance corresponding to the distance between said vertical supports, the upper portion of said web disposed between said slots being woundable on said lateral supports.
Claim 8
Dependent Claim 15 words
The wall partition according to claim 1, wherein said filler material is made from rubber.
