Movable partition systems include an elongated, fixed drive member extending along a track, a partition that is automatically and manually movable along the track, and a motor carried by the movable partition configured to drive a rotatable drive member that is engagable with the elongated, fixed drive member. The rotatable drive member may be engaged with, and disengaged from, the fixed drive member. Methods of moving a partition along a track include actuating a motor carried by a movable partition to drive rotation of a drive member while the drive member is engaged with an elongated, fixed drive member, and manually moving the partition along the track while the rotatable drive member is disengaged from the fixed drive member. Methods of installing a movable partition system include configuring a rotatable drive member to be capable of engagement with, and disengagement from, an elongated, fixed drive member.

The header assembly may comprise an elongated overhead track including a first channel, a second channel, and a central channel between the first and second channels. A plurality of support bracket attachment features may be included with at least one support bracket attachment feature on each of an outer surface of the first channel and an outer surface of the second channel. A support bracket may be coupled to each of the support bracket attachment features. The movable partition may comprise a plurality of panels connected to one another with hinge-like member and may be suspended from the overhead track. Embodiments of overhead tracks and methods of forming header assemblies are also disclosed.

Systems, devices, and methods for controlling a motor are disclosed. A method may include determining a rotational direction of a motor from a pair of quadrature signals sent to a microprocessor. The method further includes adjusting an internal count stored in the microprocessor at each edge of each of the pair of quadrature signals. The method further includes adjusting an external count stored in the microprocessor and transmitting an interrupt to a main controller after the first phase signal and the second phase signal have transitioned through each combinational logic state in one of a forward rotational direction and a reverse rotational direction. The method further includes transmitting a signal comprising the rotational direction of the motor and the external count from the microprocessor to a main controller.

Apparatuses and methods are provided for visual inspection across a barrier such as a fire door. In one embodiment of the present invention, a first movable partition is disposed adjacent, and laterally spaced from, a second movable partition. A first vision panel is disposed in the first partition and a second vision panel is disposed in the second partition in substantial alignment with the first vision panel. The position of the first vision panel is substantially constrained with respect to the position of the second vision panel along a first longitudinal direction. The first vision panel and the second vision panel are enabled to exhibit a desired amount of lateral displacement relative to each other.

Apparatuses, systems, and methods for providing battery-backed power to movable partitions are disclosed. A power converter generates a DC output from an AC input. The DC output may be selectively decoupled from an enabled DC output such that the DC output can be monitored for acceptable operation in-situ. The enabled DC output may be selectively coupled to a battery output terminal. A charge current may be sensed between the enabled DC output and the battery output to control charging of the battery with a pulse-width modulation operation by controlling the selective coupling of the enabled DC output to the battery output. The enabled DC output and the battery output are coupled in a logical-or configuration to generate a supply output providing current from the enabled DC output and the battery. The supply output may drive a movable partition controller and a motor configured for opening and closing a movable partition.

Methods and apparatuses are disclosed for laterally restraining a movable partition. In one embodiment, a movable partition includes two laterally spaced structures wherein each structure includes a plurality of hingedly coupled panels. A lateral restraint mechanism is located and configured to prevent lateral displacement of one or both of the two laterally spaced structures. In one embodiment, at least one bracket is substantially rigidly coupled to a hinge of the first structure and a laterally adjacent hinge of the second structure. The at least one bracket may include multiple brackets. Some described methods include laterally restraining lower edge of a movable partition as well as the installation of lateral restraint brackets including the plumbing, spacing and squaring of the structures in conjunction with such installation.

An emergency door, such as a fire door which closes automatically in case of fire, includes a nose piece which moves to an extended position when the door is closed to provide a seal of the gap otherwise present between the forward edge of the door and an adjacent door frame or door, and generally also interlocks with a mating portion of the adjacent frame or door. An addition latching element may be provided to extend from the top edge of the door and be received in a keeper when the door is closed. Door operating hardware, preferably all mounted interiorly of the door except for a push bar on one side of the door and a door handle on the other side, is operable to retract the nose piece and latching element when it is desired to open the door. The nose piece and latching element are held in retracted position when the door is open. A release device releases the latching element and nose piece to extend to extended position when the door is moved to a closed position. The release device is easily operable so the doors are reliably closeable by a door closer device. The doors may be hinged by a hinge piece received in respective door and jamb receiving channels, and if so, the hinge piece is supported by a block at the bottom of the jamb channel and the door is supported by a block at the top of the door channel.

Movable partitions may include leading end assemblies comprising an articulated leading member. The articulated leading member may be coupled to a support trolley, and at least one coupling between the articulated leading member and the trolley enables the articulated leading member to move relative to the support trolley. Methods of operating a movable partition include displacing a portion of a leading end assembly to align a majority of at least one surface of the leading end assembly with a portion of an adjacent structure.

A motor control system for a folding partition includes a data storage device and processing circuitry. The data storage device is configured to store a normal threshold profile to serve as a threshold for a measured current supplied to a motor to detect abnormal operation of the motor. The motor is configured to drive motion of the folding partition. The processing circuitry is operably coupled to the data storage device. The processing circuitry is configured to generate an adjusted threshold profile to serve as a threshold for the measured current supplied to the motor while moving the folding partition during a transition from an abnormal operational mode to the normal operational mode. The adjusted threshold profile is used for detecting additional abnormal operation of the motor. The processing circuitry is configured to generate the adjusted threshold profile by adjusting at least a portion of the normal threshold profile.

A movable partition system includes a movable partition, a floating jamb attached to an end of the movable partition and located within a pocket configured to retain the movable partition when in a retracted position, at least two base plates attached to the floating jamb, and at least two jamb stops attached to opposing interior walls of the pocket. Each of the at least two jamb stops are configured to engage a respective base plate of the floating jamb, wherein the floating jamb, the at least two base plates, and the at least two jamb stops are configured such that disengaging the floating jamb from a secure position within the pocket when the movable partition is in an extended position requires disengaging one of the at least two jamb stops from the respective base plate on each side of the movable partition. Methods of providing a security barrier are disclosed.
