Abstract:
Movable partition systems may include a chain guide structure extending along a curved path. The chain guide structure may have a specified maximum width, and may include attachment flanges that project laterally from a central beam beyond laterally outward ends of chain guide members of the chain guide structure by a specified minimum distance. Overhead support systems for movable partition systems may include such chain guide structures. Methods of forming overhead support systems and movable partition systems may include stretch forming a bent chain guide structure. Methods of installing overhead support systems and movable partition systems may include inserting fasteners at least substantially perpendicularly through attachment flanges of a chain guide structure to secure the chain guide structure to an overhead structure.
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:
A leading end assembly for a movable partition may include a frame, an exterior skin coupled to the frame for covering a leading surface and two opposing side surfaces of the frame, the exterior skin including a leading member forming at least a portion of a leading surface of the leading end assembly and at least two side members, each side member being formed separately from the leading member and forming at least a portion of a lateral side portion of the leading end assembly. Movable partitions may include leading end assemblies and leading end assemblies may be formed by related methods.
Abstract:
Closure assemblies for movable partitions may include a leading end assembly having a first side and a second side and a latching assembly coupled thereto. The latching assembly may include a first latching member having a portion thereof positioned proximate to the first side and a second latching member having a portion thereof positioned proximate to the second side. Movable partition systems may include a plurality of hingedly coupled panels movably coupled to a track, and a leading end assembly coupled to at least one panel of the plurality of hingedly coupled panels. The leading end assembly may include at least two latching features positioned on the leading end assembly. Methods of securing a movable partition may include retaining a first latching member and a second latching member in a retracted position and extending the first latching member and the second latching member to an extended position.
Abstract:
A header assembly for a movable partition includes an overhead track and a header pan. The header pan is configured to extend from the overhead track to an adjoining structure. The header pan, the overhead track, or a combination of both may form a fire-resistant barrier extending from a wall of the adjoining structure to an opposing wall of the adjoining structure. Movable partition systems may include header assemblies. Methods of forming header assemblies include positioning a header pan proximate to an overhead track and extending the header pan between a first wall and a second wall to at least substantially occlude a section of space therebetween. Methods of installing a movable partition include securing an overhead track to an overhead support structure, securing a retainer clip to an adjoining structure, extending a header pan from the overhead track to the retainer clip, and suspending a partition from the track.

Abstract:
In one embodiment, a closure assembly for a fire door, including a first lead post having a longitudinal cavity located therein, an opening extending through a wall of the first lead post into the longitudinal cavity and a locking member may be positioned within the longitudinal cavity that is configured to obstruct the opening into the longitudinal cavity upon reaching a predetermined temperature, is disclosed. In additional embodiments, fire doors including such closure assemblies and methods of locking fire doors are disclosed.
Abstract:
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.
Abstract:
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.
