ABSTRACT:
A drop seal assembly for a movable wall panel, the wall panel being situated in a room having a ceiling and a floor such that the wall panel is supported from the ceiling and is suspended above the floor. The drop seal includes a motor and an actuator operatively connected to the motor and movable between a first actuator position and a second actuator position in response to the operation of the motor. The drop seal also includes a mechanism, such as a compression spring, connected to the actuator and a retractable seal connected to the spring such that when the actuator is in its first position, the seal does not engage the floor, and when the actuator is in its second position, the seal engages the floor, the spring biasing the seal toward the floor to effectively seal the panel against the floor.
