Abstract:
A partition which forms a substantially draft-free fire barrier comprising:an opening;an at least one first panel;said at least one first panel being mounted rotationally on hinges;said rotationally mounted at least one first panel having an opened and closed position to open and close said opening;a mechanism to close said rotationally mounted at least one first panel;said closing mechanism being disposed to move said rotationally mounted at least one first panel into the closed position;said closing mechanism comprising an arrangement for storing energy to close said rotationally mounted at least one first panel without energy being transferred to said closing mechanism from outside said closing mechanism;a device to retain said rotationally mounted at least one first panel;said retaining device being disposed to hold said rotationally mounted at least one first panel in the open position;said retaining device comprising an arrangement to release said rotationally mounted at least one first panel;an at least one second panel;said at least one second panel being disposed to be horizontally movable;said at least one second panel having an opened and closed position to open and close said opening;a detection system to sense combustion;said combustion-sensing detection system being operatively connected to close said rotationally mounted at least one first panel;said partition is openable and closable;said at least one second panel comprises one of a sliding door and a telescoping door;a frame;said frame being disposed and configured to support said at least one second panel;a profile;said profile being disposed adjacent to said at least one first panel;said frame being disposed to be affixed to said profile;a drive mechanism;said drive mechanism being operatively connected to said at least one second panel;said drive mechanism being configured to move said at least one second panel;an auxiliary drive mechanism being configured and disposed to move said at least one second panel;said auxiliary drive mechanism being configured to store energy upon movement of said at least one second panel from said opened position to said closed position;a switchable coupling;said switchable coupling being able to be activated to transmit power and able to be deactivated to end transmission of power;said switchable coupling being connected to said drive mechanism;a drive belt;said drive belt being disposed to connect said drive mechanism to said at least one second panel;said switchable coupling being configured and disposed to disconnect said drive mechanism from said drive belt upon said coupling being in said deactivated condition; andsaid auxiliary drive mechanism being configured to move said at least one second panel into said opened position upon said switchable coupling disconnecting said drive belt from said drive mechanism.
