A mobile partition wall includes a plurality of adjoining wall elements 1. In order to prop and stabilize each wall element 1 between the ceiling and the floor and to provide noise insulation, each wall element includes an upper seal bar 8 and a lower seal bar 9. The seal bars 8, 9 cooperate with a pneumatic stroke or force device 20 via a linkage 16, 16'. The stroke device 20 preferably includes a pneumatic bellows. A pneumatic coupling is arranged on each of the two narrow vertical edges of each wall element 1. When adjacent wall elements are pushed against one another, the respective adjacent couplings engage or couple with one another, whereby a non-return or poppet-type valve is opened to allow the flow of pressurized air. The pressurized air actuates the stroke device 20, which extends the seal bars 8, 9 outwardly to press against the upper support track and the floor.
A wall element for a mobile partition wall to be arranged on a support track, the wall element comprising a wall element body, an upper seal member arranged vertically movably relative to said wall element body along a top edge of said wall element body, a lower seal member arranged vertically movably relative to said wall element body along a bottom edge of said wall element body, at least one pneumatic stroke device cooperating with said upper and lower seal members to apply a vertically directed force to said seal members, first and second pneumatic couplings respectively arranged at first and second side edges of said wall element body, and a manually operable decompression valve pneumatically connected to said stroke device, wherein said first and second couplings and said pneumatic stroke device are pneumatically interconnected, and wherein at least said first coupling comprises a pneumatic valve.
A wall element for a mobile partition wall to be arranged on a support track, the wall element comprising a wall element body, an upper seal member arranged vertically movably relative to said wall element body along a top edge of said wall element body, a lower seal member arranged vertically movably relative to said wall element body along a bottom edge of said wall element body, at least one pneumatic stroke device cooperating with said upper and lower seal members to apply a vertically directed force to said seal members, first and second pneumatic couplings respectively arranged at first and second side edges of said wall element body, wherein said first and second couplings and said pneumatic stroke device are pneumatically interconnected, wherein at least said first coupling comprises a pneumatic poppet-type valve, wherein said second coupling comprises a coupling bolt configured to cooperate with said poppet-type valve to open said valve when said first and second couplings of two adjacent ones of said wall elements are pushed into coupling engagement, a bias spring urging said coupling bolt outwardly relative to said wall element, and a decoupling arm connected to said coupling bolt, and wherein said decoupling arm is manually operable to pull said bolt inwardly and out of coupling engagement with said poppet-type valve of said first coupling.
A mobile partition wall comprising a support track mounted on the ceiling of a room and a plurality of wall elements, wherein each of said wall elements comprises a wall element body, an upper seal member arranged vertically movably relative to said wall element body along a top edge of said wall element body, a lower seal member arranged vertically movably relative to said wall element body along a bottom edge of said wall element body, at least one pneumatic stroke device cooperating with said upper and lower seal members to apply a vertically directed force to said seal members, first and second pneumatic couplings respectively arranged at first and second side edges of said wall element body, and a manually operable decompression valve pneumatically connected to said stroke device, wherein said first and second couplings and said pneumatic stroke device are pneumatically interconnected, and wherein at least said first coupling comprises a pneumatic valve, each of said wall elements further comprising a support carriage for engaging and riding along said track, said carriage comprising a carriage body and a riding element selected from the group consisting of a roller wheel and a roller ball.
