Embodiments of the disclosure relate generally to wire supports for movable partition systems, movable partition systems including such wire supports, and related methods. Specifically, embodiments of the disclosure relate to wire supports for suspending wires extending within a space between two movable partitions.
Movable partitions are utilized in numerous situations and environments for a variety of purposes. Such partitions may include for example, foldable or collapsible doors configured to close off an opening in order to enclose a room or to subdivide a single large room into one or more smaller rooms. The subdivision of one or more larger areas may be desired, for example, to accommodate the simultaneous meeting of multiple groups in different areas of a larger partitioned space. In some applications, movable partitions are useful for providing privacy and noise reduction. In some applications, movable partitions are useful for providing a barrier, such as, for example, a security barrier or a fire barrier.
A partition system may further include wires extending from one end of the partition system to an opposite end of the partition system. For example, wires may connect an AC or DC electrical power supply at one end of a movable partition to a drive motor for extending and retracting the movable partition at an opposing end of the movable partition. In addition, wires may electrically interconnect various components (e.g., switches, sensors, and controllers) of one or more electronic systems of the movable partition system, such as to alarm systems, partition monitoring systems, and partition control systems. In previously known partition systems, wires have been located in a space within the movable partition between two parallel extending sheets of folding panels that together define the movable partition. Wires are typically connected to individual panels of one of the sheets of folding panels using clips to support the wires as they extend from one end of the movable partition to the opposing end of the movable partition. Thus, the wires are coupled to the interior surfaces of the folding panels, and bend in conformity with the panels in an according-style fashion as the movable partition is extended and retracted.
While the specification concludes with claims particularly pointing out and distinctly claiming what are regarded embodiments of the invention, various features and advantages of disclosed embodiments may be more readily ascertained from the following description of some example embodiments when read in conjunction with the accompanying drawings, in which:

A wire-supporting member 16 through which wire may be inserted and from which wire may be suspended may be rotatably connected to the cantilever member 12. For example, the wire-supporting member 16 may include a space 18 through which wire may extend and a supporting structure 20 located below the space from which the wire may be suspended. The supporting structure 20 of the wire-supporting member 16 may comprise a loop 22 of an eyebolt 24 in some embodiments. In other embodiments, the wire-supporting member 16 may comprise a loop, an eyelet, a grommet, a section of non-corrugated conduit, a hook, or any other structure known in the art through which wire may be inserted and from which wire may be suspended. In some embodiments, an optional section of corrugated conduit (not shown) through which wire may extend may be inserted through and retained by the loop 22.
The wire-supporting member 16 may be connected to the cantilever member 12 using a rotatable connection 26. The rotatable connection 26 may enable the wire-supporting member 16 to swivel and pivot with respect to the cantilever member 12. Additional detail regarding the rotatable connection 26 is provided below in connection with the discussion of

The movable partition 60 may comprise, for example, an accordion-type folding door. The movable partition 60 may include two sheets of panels 62 extending at least substantially parallel to one another connected at their ends to define an interior space between the sheets of panels 62. Each sheet of panels 62 may include a plurality of panels 64 hingedly connected to one another with hinges or other hinge-like members 66, which may comprise separate structures from the panels 64 or may be integrally formed with the panels 64 and interconnected to form the sheet of panels 62. The hinged connection of the panels 64 enables the panels 64 to fold, and the movable partition 60 to collapse, in a plicated manner as the movable partition 60 is retracted, which enables the movable partition 60 to be stored compactly in a pocket 68 formed in a wall 70A of a building when in a retracted state. In other embodiments, the movable partition 60 may comprise a sliding door, or another type of movable partition 60.
When the movable partition 60 is deployed to an extended position, the movable partition 60 is driven along a track 72 across the space to provide an appropriate barrier. The track 72 may comprise an overhead track disposed in a header assembly 74. In such embodiments, the movable partition 60 may be suspended from and movable along the track 72.

The movable partition system 58 may include a first sheet of panels 62A and a second sheet of panels 62B laterally spaced from and extending substantially parallel to the first sheet of panels 62A. The first ends 76 of the first and second sheets of panels 62A and 62B may be attached at or near the lead post 78. For example, the first and second sheets of panels 62A and 62B may be attached directly to the lead post 78, may be attached to one another and then to the lead post 78, or may be attached to an intermediate structure that is then attached to the lead post 78. Such a movable partition 60 may be used, for example, as a fire door, wherein one sheet of panels 62A acts as a primary fire and smoke barrier, an interior space 84 between the first sheet of panels 62A and the second sheet of panels 62B acts as an insulator or a buffer, and the second sheet of panels 62B acts as a secondary fire and smoke barrier. Such a configuration may also be useful in providing an acoustic barrier when the movable partition 60 is used to subdivide a larger space into multiple rooms.
In some embodiments, the movable partition system 58 may also include an automatic drive system 86. The automatic drive system 86 may be disposed in the interior space 84 between the first sheet of panels 62A and the second sheet of panels 62B. The automatic drive system 86 may be attached to and carried by the movable partition 60, and may move cooperatively therewith as the movable partition 60 is extended or retracted. In some embodiments, all of the drive components of the movable partition system 58 may be confined between the first sheet of panels 62A and the second sheet of panels 62B.
The automatic drive system 86 may be positioned near the lead post 78 of the movable partition system 58. The automatic drive system 86 may include a motor (not shown) carried by the movable partition 60 as described in detail in U.S. patent application Ser. No. 12/542,448 which was filed Aug. 17, 2009 and is entitled “Methods, Apparatuses, and Systems for Driving a Movable Partition,” in U.S. patent application Ser. No. 12/758,584, which was filed Apr. 12, 2010 and is entitled “Methods, Apparatuses, and Systems for Movable Partitions,” and in U.S. patent application Ser. No. 12/838,235, which was filed Jul. 16, 2010 and is entitled “Methods, Apparatuses, and Systems for Movable Partitions,” the disclosure of each of which is hereby incorporated herein in its entirety by this reference. Briefly, the automatic drive system 86 may be configured to automatically open, automatically close, or to both automatically open and automatically close the movable partition 60 upon actuation thereof. The automatic drive system 86 may include an elongated drive member (not shown), which may comprise, for example, a chain, belt, cable or rope having fixed ends. A rotatable drive member 88, such as, for example, a pulley, wheel, cog, or sprocket, may be configured to engage the elongated drive member such that when the rotatable drive member 88 is rotated, the rotatable drive member 88 moves along the elongated drive member causing the movable partition 60 to automatically extend to a deployed state or automatically retract to a collapsed state.
In other embodiments, the automatic drive system 86 may comprise a motor or other actuator for extending a movable partition fixedly located in the pocket 68. For example, a drive system as disclosed in U.S. Pat. No. 7,782,019 issued Aug. 24, 2010 to Banta et al., the disclosure of which is incorporated herein in its entirety by this reference, may be used.
The movable partition system 58 may also include a control system 90. For example, the control system 90 may comprise a control system as disclosed in U.S. Pat. No. 6,662,848, issued Dec. 16, 2003 to Goodman et al., the disclosure of which is incorporated herein in its entirety by this reference. The control system 90 may be operatively coupled to the automatic drive system 86 (e.g., using a wire 46 or a plurality of wires 46 as shown in
At least one wire support 10 (e.g., a plurality of wire supports 10) may be disposed in the interior space 84 between the second, opposing end 82 and the first end 76 of the movable partition 60. Each cantilever member 12 may be secured to a panel 64 of one of the first and second sheets of panels 62A and 62B. For example, the cantilever member 12 of a first wire support 10A may be attached to the first sheet of panels 62A and the cantilever member 12 of a second wire support 10B may be attached to the second sheet of panels 62B. Thus, a movable partition system 58 including a plurality of wire supports 10 may include wire supports 10 secured to each sheet of panels 62 of the movable partition 60 in some embodiments. In other embodiments, each wire support 10 may be secured to the same sheet of panels 62, though to different panels 64 of that sheet of panels 62, of the movable partition 60. The wire supports 10 may be connected to the panels 64 by abutting the connection surfaces 14 (see
The wire-supporting member 16 of at least one wire support 10 may be positioned at least substantially equidistant from the first and second sheets of panels 62A and 62B. For example, the wire-supporting member 16 may be within about 1 inch (2.54 cm) from a location equidistant from the first and second sheets of panels 62A and 62B, may be within about 0.5 inches (1.27 cm) from such a location, or may be located at such a location. An end 94 of the cantilever member 12 located opposite an end to which the rotatable connection 26 is attached may abut a hinge or hinge-like member 66 joining the panel 64 to which the wire support 10 is attached to another panel 64. Accordingly, the cantilever member 12 may have a length and geometry configured to extend between the hinge or hinge-like member 66 and a location equidistant from the first and second sheets of panels 62A and 62B. For example, the cantilever member 12 may comprise an L-shaped member having a first portion 96 connected to the panel and having a first length L1 and a second portion 98 extending at about a 90° angle from the first portion 96 and having a second length L2. The first length L1 may be about 6.5 inches (16.51 cm) and the second length L2 may be about 1 inch (2.54 cm), in some embodiments. For example, the first length L1 may be between about 5.5 inches (13.97 cm) and 7.5 inches (19.05 cm), between about 6 inches (15.24 cm) and 7 inches (17.78 cm), or 6.5 inches (16.51 cm). In a similar manner, the second length L2 may be between about 0.5 inches (1.27 cm) and 1.5 inches (3.81 cm), between about 0.75 inches (1.91 cm) and 1.25 inches (3.18 cm), or 1.0 inch (2.54 cm).
When installing the wire support 10, the end 94 of the cantilever member 12 opposing the end to which the rotatable connection 26 is attached may be abutted against the hinge or hinge-like member 66 of a panel 64 and the connection surface 14 may be abutted against the panel 64. The wire support 10 may then be secured to the panel, for example, by adhesively joining, welding, riveting, screwing, bolting, or otherwise connecting the cantilever member 12 to the panel 64. Thus, the wire support 10 may enable faster and easier installation of the movable partition system 58 as compared to clips connected to individual panels 64 because fewer connections are required and because the shape and configuration of the wire support 10 may enable installation with relatively few actions performed. Forming the cantilever member 12 as an L-shaped member may enable the wire-supporting member 16 to stay in a position at least substantially equidistant from the first and second sheets of panels 62A and 62B because, as the movable partition 60 extends and retracts, the panels 64 to which the wire supports 10 are attached will rotate on their hinges or hinge-like members 66 and the L-shape of the cantilever member 12 may reduce displacement of the wire-supporting member 16 as the wire support 10 rotates along with the panel 64 as compared to a cantilever member 12 that comprises only a straight, first portion 96.
At least one wire 46 may extend in the interior space 84. The wire 46 may be inserted through the wire-supporting member 16 of each wire support 10. Thus, the wire 46 may be suspended from and at least partially supported by the wire supports 10. The wire 46 may extend from the first end 76 of the movable partition 60 to the second, opposing end 82 of the movable partition 60, or may extend to locations near the first and second, opposing ends 76 and 82.
Referring to
At least one wire support 10 comprising a cantilever member 12 and a wire-supporting member 16 through which wire 46 may be inserted rotatably connected to the cantilever member 12 may be connected to at least one panel 64 of a sheet of panels 62 in the interior space 84 (see
The wire 46 extending in the interior space 84 (see
As the wire 46 extends in the interior space 84 (see
Portions of the wire 46 located between the second, opposing end 82 and the first end 76 of the movable partition 60 may be supported by wire-supporting members 16 of wire supports 10, which are rotatably connected to cantilever members 12 secured to panels 64 of the sheet of panels 62. For example, a wire support 10 may be added for at least about every 10 feet (3.05 m) that a movable partition 60 must extend to reach a fully deployed state. Thus, for movable partitions 60 that must extend for between about 10 feet (3.05 m) and about 20 feet (6.10 m) to reach a fully deployed state, at least one wire support 10 may support wire 46 extending between the first and second, opposing ends 76 and 82 of the movable partitions 60. For movable partitions 60 that must extend for between about 20 feet (6.10 m) and about 30 feet (9.14 m) to reach a fully deployed state, at least two wire supports 10 may support wire 46 extending between the first and second, opposing ends 76 and 82 of the movable partitions 60. Thus, movable partition systems 58 may comprise one wire support 10 or a plurality of wire supports 10 disposed in the interior space 84 between first and second sheets of panels 62A and 62B (see
Finally, a portion of the wire 46 located near the first end 76 of the movable partition 60 may be supported by a relief connection 104 located proximate the first end 76. For example, the wire 46 may be connected to the electric drive motor 102 located at or near the first end 76 and carried by the movable partition 60 and a portion of the wire 46 proximate the electric drive motor 102 may be supported by a relief connection 104 attached to the automatic drive system 86 containing the electric drive motor 102. Thus, the weight of the wire 46, vertical forces acting on the wire 46, and vertical force components acting on the wire 46 may be supported by components of the movable partition system 58 other than the electrical connections to electrical components, which may reduce strain on the electrical connections.
When the movable partition 60 is in a collapsed state within the pocket 68, the wire 46 may hang from the relief connections 104 and the wire-supporting members 16 of the wire supports 10 toward a floor 108 or other bottom surface. For example, the wire 46 may be at least 12 inches (30.48 cm) away from the floor 108, at least 6 inches (15.24 cm) away from the floor 108, or at least 1 inch (2.54 cm) away from the floor 108 at its lowest points when the movable partition 60 is in a collapsed state. As the movable partition 60 extends from a collapsed state to a deployed state, the wire supports 10 supporting the wire 46 may move along with the panels 64 to which they are secured while the lowest points of the wire 46 raise with respect to the floor 108 toward the track 72 so that the wire 46 may maintain the electrical connections between components of the movable partition system 58.
As compared to movable partition systems where wire is connected to one of the movable partitions using clips to support the wires as they extend from the proximal end to the distal end of the movable partition system, the wire supports 10 may enable wire 46 to provide a more reliable electrical connection because the wire 46 is not forced to conform to the accordion-like bending of the sheets of panels 62A and 62B. In addition, the wire supports 10 may enable thicker wire 46 to be used because such wire 46 does not have to conform to the accordion-like bending of the sheets of panels 62A and 62B. The wire supports 10 may also enable the wire 46 to provide a more reliable electrical connection because air within the interior space 84 acts as a buffer between the wire 46 and surfaces (e.g., panels 64) that may be directly exposed to fire (e.g., when the movable partition 60 acts as a barrier to fire). The wire supports 10 may enable shorter lengths of wire 46 to be used because the wire may have a more direct path between the components connected to the wire 46. For example, the wire supports 10 may enable a length of wire 46 that is about three-fourths as long, two-thirds as long, or even one-half as long as a length of wire 46 connected to the same movable partition 60 using clips connected to panels 64. The wire supports 10 may enable faster and simpler installation because fewer structures (e.g., wire supports 10 and relief connections 104) are required to support the wire 46.
