Portable wall partition

Claim 1

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.
