BACKGROUND OF THE INVENTION

The present invention relates to the finishing or fitting-out of building space and the like of the type having a generally open plan interior, and in particular to an integrated prefabricated partition system that includes movable frames with vertical utility channels.

The finishing or fitting-out of building spaces for offices, medical treatment facilities, and other areas where work is conducted has become a very important aspect of effective space planning and layout. Work patterns, technology, and business organizations are constantly evolving and changing. The building space users require products which facilitate change at lower cost, yet provide the privacy and aesthetic advantages of permanent floor-to-ceiling architectural wall systems. Space planning is no longer a static problem. Changing technology and changing work processes demand that a design and installation be able to support and anticipate change.

These space planning challenges are driven largely by the fact that modern office spaces are becoming increasingly more complicated and sophisticated due to increasing needs of the users for improved utilities support at each workstation or work setting. These "utilities," as the term is used herein, encompass all types of resources that may be used to support or service a worker, such as communications and data used with computers and other types of data processors, telecommunications, electronic displays, etc., electrical power, conditioned water, and physical accommodations, such as lighting, HVAC, sprinklers, security, sound masking, and the like. For example, modern offices for highly skilled "knowledge workers" such as engineers, accountants, stock brokers, computer programmers, etc., are typically provided with multiple pieces of very specialized computer and communications equipment that are capable of processing information from numerous local and remote data resources to assist in solving complex problems. Such equipment has very stringent power and signal requirements, and must quickly and efficiently interface with related equipment at both adjacent and remote locations. Work areas with readily controllable lighting, HVAC, sound masking, and other physical support systems, are also highly desirable to maximize worker creativity and productivity. Many other types of high technology equipment and facilities are also presently being developed which will need to be accommodated in the work places of the future.

The efficient use of building floor space is also an ever-growing concern, particularly as building costs continue to escalate. Open office plans have been developed to reduce overall office costs, and generally incorporate large, open floor spaces in buildings that are equipped with modular furniture systems, which are readily reconfigurable to accommodate the ever-changing needs of a specific user, as well as the divergent requirements of different tenants. One arrangement commonly used for furniture open plans includes movable partial height partition panels that are detachably interconnected to partition off the open spaces into individual work settings and/or offices. Such partial height partition panels are configured to receive hang-on furniture units, such as worksurfaces, overhead cabinets, shelves, etc., and are generally known in the office furniture industry as "systems furniture." Another arrangement for dividing and/or partitioning open plans involves the use of modular furniture, in which a plurality of differently shaped, complementary free-standing furniture units are positioned in a side-by-side relationship, with upstanding partial height privacy screens available to attach to selected furniture units to create individual, distinct work settings and/or offices. All of these types of modular furniture systems have been widely received due largely to their ability to be readily reconfigured and/or moved to a new site, since they are not part of a permanent leasehold improvement.

In order to gain increased efficiency in the use of expensive office real estate, attempts are now being made to try to support highly paid knowledge workers with these types of modular furniture systems in open office settings, instead of conventional private offices. However, in order to insure peak efficiency of such knowledge workers, the work settings must be equipped with the various state-of-the-art utilities and facilities discussed above. Since such work settings must be readily reconfigurable to effectively meet the ever-changing needs of the users, the distribution and control of utilities throughout a comprehensive open office plan has emerged as a major challenge to the office furniture industry. The inherent nature of modular furniture systems, which permits them to be readily reconfigurable into different arrangements, makes it very difficult to achieve adequate utility distribution and control.

Today's office workers need new flexible alternative products for the creation of individual and collaborative spaces which allow the expression of the cultural aims of the organization, express the creativity of the designer, provide a "sense of place" for the users, and provide a competitive edge for the developer. These needs include a full range of privacy options, from fully enclosed offices which support individual creative work to open spaces for collaborative team work. The products must also be able to accommodate diverse organizations, unique design signatures, and constantly changing work processes. Workers also need effective lighting, better air quality, life safety, and ergonomic task support to promote productivity, minimize the expenses of absenteeism and workman's compensation, and reduce potential liability.

Hence, utility distribution and control are fast becoming one of the major issues in office fit-out and furniture. Changing technology is creating greater demands on power and signal distribution networks. As businesses become more aware of the impact of proper ventilation and climate control on employee health and performance, HVAC is becoming more important as well. The current disposition of HVAC, lighting, and fire protection in the ceiling creates a separation between these services and the work settings below leading to inefficient and inaccurate systems. Routing power and signal distribution below the floor or in furniture systems often ends up in complex idiosyncratic systems which are difficult to manage or change.

Furthermore, due to dimensional variations in existing permanent building walls, ceiling, and floors, space-dividing systems must be adaptable to accommodate these variables. Meeting the varied requirements of office workers within a given facility may require a combination of full and partial height dividers to provide a range of privacy levels corresponding to an individual user's job functions. However, presently available full height architectural walls are not readily reconfigurable, cannot be readily interconnected with partial height dividers, and also do not provide integrated utility distribution between the various types of dividers in the office space.

There is presently an oversupply of office space and furniture systems which do not properly respond to, or support change. Many older buildings do not have adequate utility capabilities, and the cost of conventional renovations or improvements often renders the same impractical. Even relatively new buildings can be quickly rendered obsolete by the fast paced changes in modern technology. The refurbishing of existing building space is therefore a concern which must be addressed by furniture systems.

One type of movable wall which may be used as a part of a solution to those issues noted above is a solid core partition, which has substantial sound transmission resistance. The use of a solid gypsum core provides significant structural and acoustic benefits, at a relatively low cost. However, conventional solid core partitions are typically custom built floor-to-ceiling installations, which do not adequately address the aforementioned concerns of routing utilities through the partition system. The lack of a prefabricated, modular design normally increases costs and installation time. Also, the use of a solid gypsum core, while being acoustically beneficial, inherently provides problems in high tech offices which require substantial power and cable support.

SUMMARY OF THE INVENTION

One aspect of the present invention is to provide a movable panel and associated frame for reconfigurable office partitions and the like, with an improved rigid stile disposed in a normally vertical orientation. The stile includes first and second channels extending longitudinally therealong which are shaped to receive utilities therein through outwardly opening sides. The outwardly opening sides of the first and second channels are juxtaposed in opposite directions to facilitate routing utilities therein along opposite faces of the frame.

Another aspect of the present invention is a movable panel for reconfigurable office partitions and the like. The panel includes a base shaped to be supported along a floor surface, and a top shaped to be supported along a ceiling surface. A prefabricated rigid frame is supported between the base and the top, and includes at least two stiles disposed in a normally vertical orientation, and extending on opposite sides thereof. At least two cross-members extend between and connect to the stiles in a vertically spaced-apart relationship to define with the stiles a pocket therebetween. A core panel, having a solid interior construction that provides a sound barrier, is mounted in the pocket. The stiles each include at least one channel, which extends longitudinally therealong and is shaped to receive utilities therein through outwardly opening sides. At least one cover panel is detachably mounted on the frame, and encloses at least a portion of opposite faces of the panel.

Yet another aspect of the present invention is in a movable partition panel of the type having a bottom, a top, opposite first and second faces, and opposite sides adapted for detachable connection with like panels. A first channel extending continuously from the bottom to the top of the panel in a normally vertical orientation defined by a closed rear side and shaped to receive utilities therein with an open outwardly oriented side through which utilities are inserted into the first channel. A second channel extends continuously from the bottom to the top of the panel in a normally vertical orientation defined by a closed rear side and shaped to receive utilities therein with an open outwardly oriented side through which utilities are inserted into the second channel. The first and second channel s are oriented in opposite directions, such that the first channel opens toward the first face and the second channel opens toward the second face, thereby permitting utilities to be routed vertically along both faces of the panel.

Yet another aspect of the present invention is a stile for reconfigurable partition frames. The stile includes a rigid upright having first and second channels extending longitudinally therealong and being shaped to receive utilities therein through outwardly opening sides. The outwardly opening sides of the first and second channels are juxtaposed in opposite directions to facilitate routing utilities therein along opposite faces of the partition frame.

Yet another aspect of the present invention is a reconfigurable office partition system including a floor track shaped to be supported along a floor surface, and a ceiling track shaped to be supported along the ceiling surface. A plurality of prefabricated rigid frames are supported between the base and the top. Each frame includes at least two stiles disposed in a normally vertical orientation, and extending along opposite sides thereof. The stiles each include at least one channel extending longitudinally therealong and being shaped to receive utilities therein through outwardly opening sides. The frames each include at least two cross-members extending between and connected to the stiles in a vertically spaced-apart relationship to define with the stiles a pocket therebetween. A core panel is mounted in the pocket, and has a solid interior construction that provides a sound barrier. A plurality of connectors detachably interconnect the frames in a side-by-side relationship, and a plurality of cover panels are detachably mounted on the frames, and enclose opposite faces of the panels.

Yet another aspect of the present invention is a movable panel for reconfiguring floor-to-ceiling office partitions and the like. The panel includes a floor track shaped to be supported on a floor surface. A ceiling track is shaped to be supported on a ceiling surface, and defines between the ceiling track and the floor track a floor-to-ceiling height. A prefabricated rigid panel frame is supported in a normally vertical orientation between the floor track and the ceiling track, and has a predetermined height less than the floor-to-ceiling height. The panel frame has a base portion operably connected with the floor track, and a top portion spaced vertically apart from the ceiling track. A variable height support extends between and interconnects the panel frame and the ceiling track. The panel support is vertically extensible, and includes a lock which rigidly retains the panel support at a selected height. At least one cover panel is detachably connected with at least one of the panel frame and the panel support, and encloses an associated portion of the same.

The principal objects of the present invention are to provide a solid core panel for reconfigurable office partitions and the like, which has substantial structural and acoustic properties, yet is capable of readily routing utilities, such as power and cable lines, along opposite faces of the panel. Preferably, the panel has a prefabricated, modular construction to reduce manufacturing costs and installation time, and is adaptable for use in floor-to-ceiling applications. The panel has vertically adjustable top and base members to accommodate a wide variety of applications. The panel is very durable, can be easily and quickly installed, efficient in use, and particularly adapted for the proposed uses.

These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

For purposes of description herein, the terms "upper," "lower," "right," "left," "rear," "front," "vertical," "horizontal," and derivatives thereof shall relate to the invention as oriented in FIG. 1. However, it is to be understood that the invention may assume various orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

The reference numeral 1 (FIG. 1) generally designates a reconfigurable office partition system embodying the present invention, which is particularly designed for use in office spaces, and other similar settings and environments. In the illustrated example, the reconfigurable office partition system 1 includes at least one movable panel 2 with a rigid frame 3, a core panel 4 mounted therein, and at least one cover panel 5 detachably mounted on the frame 3 and enclosing an associated portion thereof. The frame 3 has at least one vertical side member or stile 6 (FIG. 2) with a first channel 7, and a second channel 8, each of which extend longitudinally along the vertical stile 6, and are shaped to receive utilities such as electrical power lines 9 or communications lines therein through outwardly-opening sides 10, 11. The outwardly-opening sides 10, 11 of the channels 7, 8 are juxtaposed in opposite directions to facilitate routing utilities along both faces 26, 27 of the panel 2. A variable height support 12 may be positioned between the top of the panel 2 and the building ceiling 13 for floor-to-ceiling applications.

As best seen in FIG. 2, the prefabricated rigid frame 3 of the present invention includes a pair of horizontally spaced-apart, vertically disposed stiles 6. Corresponding pairs of horizontal cross-members 14, 15, 16, 17 and 18 are welded to opposite side faces 19 and 20 of the vertical stiles 6. Each of the horizontal cross-members includes at least one horizontal row of slots 21 for removably supporting hang-on accessory units such as worksurfaces, storage bins, and the like (not shown). As described in more detail below, slots 21 also provide for connection of off-module panels 22 (FIG. 1). Stiles 6 and the other horizontal frame members may be fabricated from sheet metal by a roll-forming process.

With further reference to FIGS. 3-5, core panel 4 is preferably a gypsum sheet which is connected to stiles 6 along opposite side edges 23 and 24 by a plurality of fasteners, such as self-drilling screws 25. Although core panel 4 is preferably a gypsum sheet, the core panel could be constructed from other materials, including sheet metal, fiberglass or other materials that provide an acoustic barrier and/or sound-absorbing properties. Furthermore, core panel 4 could have a composite construction, wherein a sheet metal skin is combined with a fiberglass mat or other sound-absorbing material. The core panel 4 provides acoustical insulation, and, in combination with the floor-to-ceiling construction of the movable panel 2, forms a continuous acoustic barrier that provides greater privacy than partial-height office panel systems. However, because the cover panels 5 do not obstruct the horizontal rows of slots 21, the reconfigurable office partition 1 of the present invention provides for hang-on accessory units (not shown), and also provides for attachment of off-module wall panels 22 in a manner that is not possible with conventional architectural walls.

The channels 7 and 8 formed by the vertical stiles 6 permit utilities such as power and communications lines and the like to be routed vertically from the floor to the ceiling. The second vertical channels 8 permit routing utilities along the first side face 26 (FIG. 4) of the panel 2, and the first channels 7 permit routing utilities along the second side face 27 (FIG. 6) of the movable panel. As described in more detail below, power and communications receptacles can be mounted at various locations on the panel, thereby providing utilities throughout the office space as required for a given application. Although the frame 3, including vertical stiles 6, can form a floor-to-ceiling partition, frame 3 may also form part of a partial height panel system if required for a particular application.

A floor track 30 (FIG. 5) is disposed directly below the panel frame 3, and is shaped to support the panel 2 on the floor surface 31. In the illustrated example, a pair of jack screws 32 extend downwardly from lower horizontal frame member 33 and engage openings 34 (FIG. 8) in the floor track 30. Jack screws 32 permit the panel frame 3 to be vertically adjusted to account for variations in the existing floor surface 31. As described in more detail below, upper and lower panel-to-panel connector brackets 40 and 41 (FIGS. 4, 6) each include a plurality of clearance holes 42 that receive fasteners for interconnecting adjacent panels 2.

With reference to FIG. 9, the illustrated variable height support 12 includes a stanchion 50 having a generally C-shaped cross section. The stanchion 50 is rigidly connected to panel frame 3 and, when assembled, extends upwardly into a structural extension 51 having a generally G-shaped cross section. A pair of fasteners such as self-drilling and/or self-tapping screws 52 (FIG. 11) rigidly connect the structural extension 51 to the stanchion 50. Fasteners 56 pass through vertically elongated slot 55 in lower portion 95 of upper bracket 53 into holes 49 in extension 51, thereby interconnecting the structural extension 51 and the upper bracket 53 in a telescoping manner to provide adjustment to account for variations in the floor-to-ceiling height (FIG. 4). If required, structural extension 51 can be cut to length during installation to provide additional vertical adjustment. Accordingly, variable height support 12 can be prefabricated, and adjusted to fit a wide range of floor-to-ceiling heights during installation. Fasteners 59, such as self-drilling and/or tapping screws, are installed through clearance holes 58 in flange 57 of the upper bracket 53 into holes 62 in web 68 of ceiling track 54, thereby securing the panel frame 3 with the ceiling track 54. Stanchion 50, structural extension 51 and upper bracket 53 are preferably formed from sheet metal such as steel, and ceiling track 54 is extruded aluminum.

An expressway 75 comprises a pair of outwardly-opening channel members 76 and 77 which are welded or bolted to the stile 6, and provide horizontal utility routing capability on each side of the panel. The channels 76 and 77 may include cut-out portions 78, such that the core panel 4 may be cut to provide cross-routing of utilities between the two sides of the panel. As best seen in FIG. 10, each channel includes a vertical web 79 with an upper horizontal web 80 and a downwardly-extending web 81 forming a downwardly-opening U-shape. Channels 76 and 77 further include a lower horizontal web 85 and a upwardly-extending flange 86 that define an expressway channel 87 to supportably retain lay-in utilities, such as power and communications lines. Clips 74 and 84 of expressway cover 83 engage flanges 86 and 82 to removably attach expressway cover 83 to a channel 76 and/or 77. Alternatively, as described in more detail below, the channels 76 and 77 may be covered by a cover panel that extends from the ceiling track 54 to flanges 86, 88 of channels 76, 77.

Ceiling track 54 includes a pair of downwardly-extending side walls 65, a pair of horizontal upper webs 66, and a pair of downwardly-extending inner flanges 67. Center web 68 extends between the inner flanges 67, and is offset from the ceiling surface 13 to define a passage 69. When assembled, flange 57 of upper bracket 53 abuts the lower surface of the center web 68, and passage 69 provides clearance for the ends of fasteners 59. As described in more detail below, ceiling track 54 also supports a cover panel 5 or a glass module 71 (FIG. 1).

With reference to FIG. 12, structural extension 51 includes side walls 90, 91 and 92, with flanges 93 and 94 extending from the side walls 92, 90, respectively. Although sidewall 90 could be flat, in the illustrated embodiment sidewall 90 is indented at 218 to retain a compressible cylindrical seal 219 along an adjacent extension 51 (see also FIG. 43). As discussed below, extension 51 may include an indented portion 217 (FIG. 43). The lower portion 95 of bracket 53 has a generally C-shaped cross section with a base wall 96, and a pair of side walls 97 and 98 extending orthogonally therefrom (FIG. 12). As discussed above, self-tapping fasteners 56 are received in clearance holes 49 (FIG. 9) of structural extension 51 through slot 55 in bracket 53 to provide telescoping adjustment to account for variations in the floor-to-ceiling height.

With reference to FIG. 13, the lower portion 60 of structural extension 51 is securely fastened to the stanchions 50 by self-drilling and/or tapping fasteners 52. Stanchion 50 has a base wall 100, with a pair of side walls 101, 102 extending transversely therefrom. The structural extension 51 forms a vertical passage 99 through which utilities may be routed. In addition, the structural extension 51 may be used along either side edge of the panel frame by inverting the structural extension 51, such that the side walls 90, 91 and 92, as well as the flanges 93 and 94 are oriented in the opposite direction, thereby providing a "mirror image" of the orientation illustrated in FIGS. 12 and 13.

With reference to FIG. 14, the stile 6 has a generally S-shaped cross section forming first and second channels 7 and 8 for vertical routing of utility lines and the like. Stiles 6 extend vertically along opposite sides of frame 3. Each stile 6 includes an inwardly-projecting mounting flange 105 defining a pocket 104 between the stiles 6 that is adapted to receive a core panel 4 therein. Self-drilling and/or tapping screws 25 or other fasteners secure the core panel 4 to inwardly-projecting mounting flange 105 of the stile 6. The first channel 7 is shaped to receive utilities, and includes a wall 110, from which transverse walls 107 and 108 extend to define an outwardly-opening side 115. Second channel 8 is also shaped to receive utilities, and includes a wall 109, from which transverse walls 106 and 107 extend to define an outwardly-opening side 116. First and second channels 7, 8 are positioned in a side-by-side relationship, with wall 107 being common to and separating the first and second channels 7, 8. Because the thickness of the core panel 4 is less than the length of the transverse wall 106, the core panel 4 is disposed at an off-center position. A side web 111 extends outwardly from the transverse wall 108, with a side flange 112 extending generally transversely therefrom. The side flange 112 includes an elongated indented channel 113 which retains an elastomeric, cylindrical seal strip 114 between adjacent side flanges 112 when a pair of adjacent frames 3 are interconnected in an end-to-end manner.

With reference to FIGS. 15 and 16, floor track 30 has a pair of lower webs 120 that abuttingly support the panel 2 on a floor surface. Floor track 30 further includes a pair of upwardly-extending step portions 121 and horizontal flange portions 122. Upwardly-extending side flanges 123 receive clip 126 of base trim 125. Upper edge 127 of base trip 125 abuts outer surface 128 of lower cover panel 5, thereby permitting the panel to be vertically adjusted using jack screw 32. A U-shaped brace 129 is welded into the channel 133, and receives the end 130 of jack screw 32.

Lower horizontal frame member 33 comprises a lower web 134 which abuts the lower end of stiles 6, a vertical web 135, horizontal web 136, and downwardly-extending outer flange 137. The outer flange 137 abuttingly supports the inner surface 124 of the lower cover panel 5.

An upwardly-extending acoustic barrier 140 is welded to the horizontal web 122 at a lower end 141, and includes an upwardly-extending flange portion 142 which is received behind the offset portion 145 of flange member 144. The upper portion 146 of flange member 144 is spot welded to stile 6 at 147 (FIG. 16). Flange member 144 includes a horizontal web 148 and a downwardly-extending outer flange 149 which supports a cover panel 5 in substantially the same manner as flange 137. Because the upwardly extending portion 142 of the acoustic barrier 140 is closely received behind offset portion 145 of flange member 144, an acoustic seal or barrier is maintained along the lower edge of the panel 2. Furthermore, the upwardly-extending portion 142 is not fixed to the panel frame 3, thereby allowing the panel to be raised and lowered relative to the floor track 30 by means of jack screws 32, while maintaining the acoustic seal. With further reference to FIG. 17, upwardly-extending flange portion 142 of acoustic barrier 140 abuts web 110 and flange 105 of stile 6.

With reference to FIGS. 18 and 19, lower panel-to-panel connector bracket 41 includes a plate 150 having an angled portion 151 and an inwardly-offset portion 152. A pair of elongated side straps 153 are welded to the plate 150, and stile 6 at 154. Upper panel-to-panel connector brackets 40 are substantially the same as brackets 41, and hence will not be described further herein. As best seen in FIG. 20, when a pair of adjacent panel frames 3 are aligned in an end-to-end manner, the clearance holes 42 of adjacent upper brackets 40 are aligned and receive fasteners 155 to rigidly interconnect the adjacent panels 2. Similarly, clearance holes 42 of adjacent lower brackets 41 also receive fasteners 155. An off-module connector bracket 156 (FIG. 19) includes an upper portion 157 having horizontal hooks that are configured to engage slots 21 of an adjacent panel to interconnect a pair of panels in an off-module configuration.
