Abstract:
A motor control system comprises a motor control circuit, a non-transitory storage medium and a processing circuitry. The storage medium is configured to store a current threshold profile that is indicative of a current requirement of the motor control circuit for an operational cycle of a motor. The processing circuitry is configured to adjust the stored current threshold profile based on a change to the operational cycle of the motor (e.g., from standard to non-standard).
Abstract:
Protective clips for movable partitions include a guard portion that protrudes from a top major surface of a base portion. The guard portion extends along the top major surface proximate to a front side of the base portion. The guard portion also may extend along the top major surface proximate to at least one end side surface at a longitudinal end of the base portion. Movable partitions include one or more such protective clips. The protective clips optionally may be used to attach a sweep strip to panels of a movable partition. Methods of forming such protective clips include molding the clips within a mold cavity.
Abstract:
Movable partition systems include a vertical alignment structure including at least one roller element coupled to a portion of a movable partition and a ramp configured to abut against the at least one roller element to vertically align the portion of the movable partition to engage with a strike plate. Methods of vertically aligning the movable partition include coupling at least one vertical alignment structure to the movable partition including coupling at least one structural frame member to the movable partition and coupling the at least one roller element to the at least one structural frame member and installing at least one ramp to an overhead structure configured to abut the at least one roller element and vertically align a leading end of the movable partition.
Abstract:
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.

Abstract:
Tensioner devices for use with movable partition systems include endplates configured to be mounted on opposing sides or ends of a movable partition. At least one of the endplates includes a bracket configured for attachment to an end of a chain or a belt. The bracket is movable relative to the endplate. The endplate having the bracket also includes an adjustment mechanism located on a common side of the endplate with the bracket, and is operably coupled with the bracket. The adjustment mechanism is configured for adjusting a distance separating the bracket from the endplate. Movable partition systems include such tensioner devices. Methods of adjusting a tension in a chain or a belt of a movable partition system involve the use of such a tensioner device. Methods of installing movable partition systems within structures include the installation of such tensioner devices.
Abstract:
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.

Abstract:
A wireless transmitter including a rotating actuator, a plate connected to the rotating actuator, and a wireless switch. The wireless switch may include at least one actuating panel and at least one transducer element. The at least one transducer element may be configured to convert mechanical energy to electrical energy. The at least one actuating panel may be configured to transmit mechanical energy to the at least one transducer element. The plate may be configured to contact the wireless switch at a rotational end point of the rotating actuator.
Abstract:
Automatic drive systems for movable partitions may comprise a floating jamb configured to attach to panels of a movable partition and glide within a pocket. A motor may be configured to extend the movable partition. The motor may be configured for mounting in the pocket on a back side of the floating jamb opposing a front side of the floating jamb to which the panels of the movable partition are configured to attach. An electronics enclosure may be sized and configured to contain electronics to connect to the motor. The electronics enclosure may be configured for positioning in the pocket on the backside in a location offset from the motor. A depth of the electronics enclosure, as measured in a direction in which the floating jamb is mounted to glide, may be less than or equal to a depth of the motor, as measured in the same direction.
