Description:
INTEGRATED PREFABRICATED FURNITURE SYSTEM FOR FITTING-OUT OPEN PLAN BUILDING SPACE 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 furniture system therefor.

The finishing or fitting-out of building spaces for offices, medical treatment facilities, and other areas where work is conducted [similar uses] 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. 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 [offices] officing spaces are becoming increasingly more complicated and sophisticated due to the ever-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, sinage, 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 d e 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 die 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 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 freestanding furniture units are positioned in a side-by- side relationship, with upstanding privacy screens available to attach to selected furniture units to create individual, distinct work settings and/or offices. All of tiiese 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 wid 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, d e work settings must be equipped with me 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 die user, me 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 die creation of individual and collaborative spaces which allow die expression of the cultural aims of the

organization, express the creativity of the designer, provide a "sense of place" for the user, 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, which collectively make the building more desirable to prospective clients. Hence, utility distribution and control are fast becoming one of me 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 d e work settings below leading to inefficient and inaccurate systems. Routing power and signal distribution below die floor or in furniture systems often ends up in complex, idiosyncratic systems which are difficult to manage or change.

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 die cost of conventional renovations or improvements often renders me same impractical. Even relatively new buildings can be quickly rendered obsolete by die fast paced changes in modern technology. The refurbishing of existing building space is dierefore a concern which must be addressed by furniture systems. SUMMARY OF THE INVENTION

One aspect of the present invention is to provide an integrated prefabricated furniture system for fitting-out building space of die type having a generally open plan interior defined by fixed walls. A demountable architectural wall system covers the fixed walls of d e associated building room, and includes a plurality of horizontally extending mounting channels which are attached to the fixed walls along upper and lower portions thereof . A plurality of horizontally extending belt zone utility troughs are attached to die fixed walls vertically inbetween die upper and lower portions thereof, adjacent to a predetermined worksurface height. A plurality of cover panels at least some of which are

full widdi and have a horizontally elongated front elevational shape, are detachably attached to die mounting channels and me utility troughs to cover the fixed walls. A portable partition wall system spatially divides the interior of the room into individual workstations or work settings, and includes a plurality of freestanding panels detachably interconnected side-by-side. The panels have internal frames, at least some of which carry a horizontally extending utility raceway positioned adjacent worksurface height, and a plurality of cover panels, each of which has a horizontally elongated front elevational shape, and is detachably mounted on opposite sides of die frames to enclose the same. The belt zone utility troughs on die demountable architectural wall system, and d e utility raceways on the portable partition zone wall system have a substantially equal width and are positioned at a common height to present a uniform horizontal appearance datum throughout the building room, and permit the continuous routing of utilities therethrough.

Preferably, die cover panels on die demountable architectural wall system and die portable partition wall panel system are substantially identical in size and shape to further reinforce the horizontal datum throughout d e building room, and permit the same to be interchanged. A demountable movable wall system provides custom widtii partitions compatible with the demountable architectural wall system and die portable partition wall system. A modular column cover system is provided to selectively enclose support columns in the building room. Pre-assembled facades cooperate with the demountable architectural wall system, the portable partition wall system, as well as new or existing GWB walls, to form glass walls and entry ways for die work settings. Pre-assembled freestanding storage cases compatible with the demountable architectural wall system and die portable partition wall system define storage for documents and die like and provide space partitioning. A space frame system is particularly adapted to support group work activities in die building interior, and includes utility raceways that cooperate with the raceways in the wall systems. A prefabricated low raised floor construction includes raceways which also cooperate witii the raceways in the wall systems and space frame. A modular overhead link head system is supported from me building structure, and routes utilities tiieretiirough to minimize fixed building wiring, plumbing, lighting, etc. A plurality of furniture accessories are provided to support die workers, and include connectors for interchangeably hanging die same from the demountable architectural wall system, die portable partition system, the demountable movable wall system, and die space frame system.

Another aspect of the present invention is to provide an integrated prefabricated furniture system for fitting-out a building room of die type having a generally open plan interior with an associated floor surface. A portable partition wall system spatially divides at least a portion of die open plan interior of the building room into a plurality of individual workstations or work settings, and includes a plurality of freestanding panels detachably interconnected side-by-side in a predetermined plan configuration. The panels have internal frames, at least some of which carry horizontally extending utility raceways positioned along an upper portion thereof . Cover panels having a horizontally elongated front elevational shape are detachably mounted on opposite sides of die frames to enclose die -same. A space frame system supports group work activities in an open portion of die interior of die building room, and includes an overhead framework comprising a plurality of frame segments interconnected in an end-to-end fashion to form a rigid structure configured to be positioned above die floor surface. A plurality of support columns are connected with the overhead framework and support the same freestanding within die building room at a predetermined elevation above average user height. A plurality of individual panels are constructed to permit easy, manual, bodily translation of die same by an adult user, and include connectors that detachably mount the same on the overhead frame at various locations therealong in a manner in which die panels hang downwardly from die overhead support in a generally vertical orientation. The panels are readily and easily manually removable dierefrom and reconfigurable thereon by die user. Utility raceways extend along die frame segments of e overhead framework, and communicate with die utility raceways on die portable partition wall panels to provide utilities diroughout the furniture system.

Yet anodier aspect of the present invention is an integrated prefabricated furniture system for fitting-out a building room of the type having a generally open plan interior. A portable partition wall system spatially divides die open plan interior of the building room into a plurality of individual workstations or work settings, and includes a plurality of freestanding panels detachably interconnected side-by-side in a predetermined plan configuration. The panels have an internal frames, at least some of which contain horizontally extending utility raceways adjacent a predetermined worksurface height. A plurality of cover panels, having a horizontally elongated front elevational shape, are detachably mounted to opposite sides of die frames to enclose die same. A demountable movable wall system forms custom widtii partitions compatible with die portable partition

wall system, and comprises a plurality of vertical studs positioned in a side-by-side relationship. A plurality of beltway channels are provided in different lengths to facilitate custom fabricating me partitions in different widtiis. The beltway channels are attached to d e studs adjacent worksurface height to rigidly interconnect the same in a mutually parallel relationship, and permit die continuous routing of utilities dierethrough with the utility raceways on the portable partition zone wall system. A plurality of cover panel detachably mount to me opposite sides of die studs to enclose die same.

The principal objects of die present invention are to provide a furniture system for finishing or fitting-out open plan building spaces that is completely prefabricated and fully integrated. A demountable architectural wall system covers the fixed walls of die building room, a portable partition wall system divides die interior space into individual and group work settings, and a demountable movable wall system forms custom widtii partitions. The three wall systems are completely compatible and fully integrated in both function and appearance, and provide similar utility raceways at common heights, as well as interchangeable cover panels. A modular cover column system selectively covers support columns in the building room, and provides vertical utility routing and storage that integrates witii the raceways in the wall systems. Pre-assembled facades cooperate with die wall systems to create finished entry ways for the work settings. A freestanding storage case system matches the wall systems for complete integration with the same, and serves as a space partition. A space frame system is particularly beneficial in supporting group work activities, and includes raceways which communicate witii the wall system raceways to effectively and efficiently distribute utilities diroughout die building room. A prefabricated low raised floor construction conforms witii the various furniture elements to provide support for work settings where the walls are inappropriate and which require maximum facility capabilities. A modular overhead link head system is supported from die building ceiling, and routes utilities tiieretiirough to minimize fixed building wiring, plumbing, lighting, etc. Furniture accessories, such as hang-on binder bins, shelves, paper managers, ambient and task lighting, displays, and die like are designed to be used anywhere diroughout die furniture system. The furniture system is readily reconfigurable to meet the ever-changing needs of the user, and minimize permanent leasehold improvements.

The furniture system provides alternatives to the architectural built wall, and also provides better performance and a higher level of finish. Because it is a factory made product, the furniture system can provide a more precise, finer level of detailing and

greater utility access, performance and flexibility at a lower cost than field built systems. The furniture system is also better adapted to accommodate more mature workers, who have greater need for privacy and utility distribution as well as higher expectations and more sophisticated tastes. The furniture system better supports facilities planning by introducing a logic and an order that is self-evidently rational from die user point of view, and supports, rather than contradicts, die distribution of services to make facility management and planning easier. The furniture system enables developers and businesses to facilitate change and create lower cost environments to support new work processes in all building types, even tiiose that are outdated and/or underutilized. The furniture system allows user control over environment, so as to create healthier work areas, which reduces stress and absenteeism. The furniture system provides improved utility distribution at lower first-time costs, as well as greater flexibility in utilities with lower life cycle costs. The furniture system is designed to interface with all types of existing buildings and building systems, and is nearly completely reusable, as well as environmentally responsible. The furniture system provides a new range of design options dirough the introduction of horizontal datum, and a wide variety of detailing options. The furniture system also allows a full range of levels of privacy from open group workspaces to fully enclose, acoustically private offices. The furniture system is efficient to use, economical to manufacture, capable of a long operating life, and particularly well adapted for die proposed use.

These and other advantages of die invention will be further understood and appreciated by tiiose skilled in die art by reference to the following written specification, claims, and appended drawings.

Preferably, mounting channels 48 include a hanger channel on which at least some of die furniture accessories may be supported, including hanging panels, ambient and task lighting, as well as hang-on storage with die use of additive support rails (not shown). The illustrated Plus wall system has both full and partial height segments. In general, Plus wall system 4 is a system of

additive architectural wall elements for adding utility and upgrading finish to existing walls. Half columns (not shown) may also be provided for vertical utility distribution along the wall surface.

The illustrated prefabricated wall system 7 (Fig. 15), which is also referred to herein as die Link wall system, is a demountable movable wall system for forming custom widtii partitions that are compatible witii d e Plus wall system 4 and the Zone wall system 5. Link wall system 7 includes a plurality of vertical studs 55, adapted to be positioned in a side-by-side relationship. A plurality of horizontal channels 56 are provided in different lengths to facilitate custom fabricating the partitions 54 in different widths. Each beltway channel 56 is shaped to be attached to die studs 55 adjacent standard worksurface height to rigidly interconnect the same in a mutually parallel relationship, and permit the continuous routing of utilities therethrough, along with tiie belt zone utility troughs 49 on Plus wall system 4, as well as Zone wall system 5. A plurality of cover panels 57 and 58 are detachably mounted on the opposite sides of studs 55 to enclose die same. In d e example shown in Fig. 15, the Link wall system 7 has base raceways 60 along the bottom edges of partitions 54, expressway raceways 61 along the top edges of partitions 54, and transoms 62 mounted on top of expressway raceways 61, which extend to die ceiling.

The illustrated storage wall system 11 (Fig. 16) includes a plurality of modular cases including file cabinets 63 and storage cabinets 64, which are designed to be arranged horizontally in a side-by-side relationship, to create both partial and full partition walls. The front faces of cabinet 63 and 64 can be oriented in eitiier direction, so as to provide access from die desired area of building room 2. In the example illustrated in Fig. 16, file cabinets 63 and storage cabinets 64 are [stacked] above eye level height, and are positioned on opposite sides of the cabinet style column cover 39 to create a wall which defines one of die work settings 6 on one side and an aisle 65 on the opposite side. The illustrated storage wall system 11 has a powered base 66 and a full expressway raceway 67. Utilities may also be distributed vertically within storage wall system 11.

The illustrated prefabricated wall system 5 (Fig. 17), which is also referred to herein as the Zone wall system, is a portable partition system that spatially defines die open plan interior of the building room 2 into individual and group work settings 6. Zone wall system 5, generally includes a plurality of freestanding panels 68 interconnected side-by- side in a predetermined plan configuration. Each Zone wall panel 68 has an internal frame 69, at least some of which includes a horizontally extending utility raceway 70 positioned

adjacent worksurface height. A plurality of cover panels 71-72 are provided, each having a horizontally elongated front elevational shape, and being detachably mounted on opposite sides of the frame 69 to enclose the same. In die illustrated examples, Zone wall panels 68 also include base raceways 74 extending along the bottom edges of die panels, and expressway raceways 61 extending along the top edges of the panels, as well as glass transoms 76 and full transoms 62. The full transoms 62 may have hollow interiors through which wires, cables and other utilities can be routed. Vertical drops are provided within the interior of panels 68 to provide power and signal anywhere between base raceway 70 and expressway raceway 61. In general, Zone wall system 5 is a stacking system which begins witii a base which provides a low height see-over sitting panel. Stackers are available to provide no see-over sitting, no see-over standing, and above door height configurations. Panels 68 can be provided in different widths to carry additional utilities. The illustrated space frame system 12 (Fig. 18) is particularly designed to support group work activities in an open portion of the open plan interior of associated building room 2. Space frame system 12 includes an overhead framework 82, comprising a plurality of frame segments 83 interconnected in an end-to-end fashion to form a rigid structure configured to be positioned above die floor surface 27. Space frame system 12 also includes a plurality of overhead support columns 84, each having an upper portion thereof connected with overhead framework 82, and a lower portion thereof shaped to abut the prefabricated floor system 13. It is to be understood tiiat space frame system 12 can also be supported directly on die floor surface 27 of building room 2. In any event, columns 84 support framework 82 in a freestanding fashion witiiin building room 2 at a predetermined elevation above average user height. Space frame system 12 also includes a plurality of individual panels 85 which have a lightweight construction to permit easy, manual, bodily translation of die same by an adult user. The panels 85 include connectors 86 that detachably mount die same on overhead framework 82 at various locations dierealong in a manner in which panels 85 hang downwardly from overhead support 82 in a generally vertical orientation, and are readily and easily manually removable therefrom and reconfigurable thereon by the user. Panels 85 may include sound attenuation to facilitate partitioning, as well as special exterior surfaces for displays. The horizontal frame segments 83 of framework 82, as well as support columns 84 include utility raceways 87 and 88 associated tiierewith to facilitate providing utilities to die associated work area. In one example of the present invention, frame segments 83 and support

columns 84 have substantially hollow constructions, forming raceways 87 and 88 therein, which are divided to physically separate power and cable wires. In the example illustrated in Fig. 18, space frame system 12 is positioned directly on top of prefabricated floor system 13, and a Zone wall panel 68 extends from the outside pair of support columns 84. The illustrated furniture accessories (Fig. 19) are designed to be used anywhere throughout furniture system 1 , and are adapted to personalize die individual work settings 6, as well as to provide support for die common work areas, such as at space frame system 12. In the example illustrated in Fig. 19, the furniture accessories include binder bins 16, shelves 17, paper managers 18, task lighting 19, displays 20, and display hooks 21. The furniture accessories 16-21 can be hung from Plus wall system 4, Zone wall system 5,

Link wall system 7, and/or column system 8. The panels 85 associated with space frame system 12 can also be hung not only from framework 82, but also from the mounting channels 48 associated witii Plus wall system 4, as well as top edges of Link wall system 7 and Zone wall system 5. In this manner, information can be prepared on panels 85 at a convenient location, and tiien transferred between the various work settings 6 and/or common work area associated with space frame system 12.

The illustrated facade system 10 (Fig. 20) includes a plurality of pre-assembled facade units 92-95 (Fig. 3), each of which includes an entry way, and is adapted for connection with wall systems 4, 5, and 7 to completely enclose a given work setting 6. Facade units 93-95 are all straight facades, and are provided in different widtiis and configurations to accommodate different interior layouts. Facade unit 96 (Fig. 20) is curved, and includes an arcuate sliding door. In the example illustrated in Fig. 20, facade units 94-96 have a glass transom 76, and full transoms 62 and 97.

The illustrated link head system 14 (Fig. 21) is designed for overhead routing of utilities throughout building room 2, and comprises plurality of like link head segments 100, each of which is supported from the structure or ceiling of building room 2, and is mutually interconnected end-to-end to define a continuous housing in which utilities are carried. In die examples illustrated in Fig. 8 and 21, two pairs of link heads 101 are arranged on opposite sides of each link head segment 100 to form two sets of vertically stacked raceways 102 and 103. Each of the link head segments 100 is mounted on an open framework 104, which is in turn suspended from the building structure by adjustable straps or struts. Modular cover panels 105 are mounted on die lower side of framework 104, and extend continuously between the opposite link heads 101 , so as to form a U-shaped

enclosure through which utility conduits, such as HVAC ducts, sprinkler pipes, power lines, communication lines, etc. can be routed through building room 2. The link heads 101 may include a flat vertically extending common rear wall with a plurality of horizontal flanges extending outwardly therefrom to form the vertically stacked columns of mutually isolated raceways 102 and 103. .An accessory hanger channel preferably extends along the lower edge of each link head 101, and is adapted to support a plurality of office accessories thereon, such as lights, motion sensors, etc. Preferably, each of the raceways 102 and 103 is dedicated to a specific type of utility, so that they can be physically separated from one another, and thereby alleviate interference. The various elements of furniture system 1 are completely compatible and fully integrated in their dimensions, finishes, connections, and utility distribution interface to create a coordinated finished building room 2. For example, the cover panels on Plus wall system 4, Zone wall system 5, and Link wall system 7 may be substantially identical in size and shape to permit the same to be interchanged. As previously noted, tiiese cover panels preferably have a horizontally elongated front elevational shape, which creates a uniform horizontal appearance datum throughout the building room 2. The cover panels are available in common and/or coordinated coverings or finishes. Also, the various raceways associated witii wall systems 4, 5, and 7, as well as column cover system 8, facade system 10, and space frame system 12 are preferably provided at common heights, so tiiat they communicate when the units are positioned side-by-side to permit the continuous routing of utilities therethrough. The vertical raceways 44 and 45 in column cover system 8 and 87 and 88 in space frame system 12 are designed to communicate with the horizontal raceways in the remaining elements of the furniture system 1 , and particularly assist in transmitting utilities between prefabricated floor system 13 and link head system 14.

Fig. 22 illustrates anotiier arrangement of furniture system 1, wherein die space frame system 12 extends between two sets of workstations 6. The two sets of workstations 6 both include expressway raceways 61 extending along die top edges of the partitioning members, and are located at a height common with the frame segments 83 of space frame framework 82 and die associated raceways 87. Consequently, the space frame framework 82 provides a canopy effect for the common area disposed between the two sets of workstations 6, and also forms conduit to route utilities, support accessories and accept infill between the two sets of workstations 6.

Fig. 23 illustrates yet another arrangement of furniture system 1, wherein the space frame system 12 forms an overhead link for of each die workstations 6. Utilities can be routed through die raceways 87 in the frame segments 83 of space frame system 12 to provide suitable utilities to the various workstations 6. Furniture system 1 is an integrated and comprehensive system of space definition and utility distribution products. It spans in function from present modular panel systems to current GWB walls, and surpasses both in terms of utility distribution, level of finish, flexibility, and integration. Furniture system 1 can provide a complete fit-out from die base building shell to the end user— including utilities, finishes, and controls. Furniture system 1 also works within existing or more traditional new construction to provide die level of performance and enclosure required by specific buildings, organizations, and users. Furniture system 1 provides a full range of enclosure and privacy options from screens that wrap around desks, to partial height walls, to completely enclosed private spaces, and completely open post and beam frameworks for collaborative work. It fills all die functions traditionally provided by panels and GWB, while offering more flexibility, more accessories, and greater utility access. Furniture system 1 is based on a horizontal division of walls into zones which allow performance criteria to be added where they will be used with the greatest comfort and efficiency. Utilities are easily accessible, finishes can be varied at different heights (for example: tackboard or white board in upper levels, more durable finishes below...) The horizontal aesthetic also recalls a traditional architectural vocabulary of wainscots, chair rails, and moldings that relates to the proportions of the human body. In furniture system 1, utilities are distributed in three horizontal zones—the kickway at the base, the beltway just above worksurface height and die expressway located just above door height. These provide a variety of utility strategies depending on die height of die installation and die utility requirements. For additional loads, there are optional, add on utility troughs which can be mounted on partial height walls. For areas witii low reconfiguration considerations, the interior of the wall can be accessed by removing the skins to provide large amounts of wiring capacity. The transoms can also carry large amounts of wires and some HVAC— and are ideally located for long distance distribution. Furniture system 1 is designed to maximize flexibility— providing access to wires for easy rewiring, the skins are removable and interchangeable, accessories can be used across all die product lines, the stacking frame can be reconfigured witii a minimum of wastage. The various cover panels can be removed and replaced in the field giving

added access the interior wall for connections and allowing refurbishment of the system witiiout any effect on the frames or utilities. The Linkhead system 14 provides access to building utilities to allow clean changes and minimize downtime. This flexibility is important to respond to die increasing frequency of change in die workplace.

In the foregoing description, it will be readily appreciated by those skilled in die art that modifications may be made to the invention without departing from die concepts disclosed herein. Such modifications are to be considered as included in d e following claims, unless tiiese claims by their language expressly state otherwise.
