Definitions

• the invention relates to overhead systems for architectural interiors and, more particularly, to a system of supported shields which permit the use of LED and other lighting elements with selectable materials surrounding the lighting elements in various configurations, so as to provide desired degrees of translucence, light intensity, texture and diffusion.
• architectural infrastructure continue to evolve in today's commercial, industrial, residential and office environments.
• architectural interiors shall be used to collectively designate these environments.
• interiors often consisted of large rooms with fixed walls, ceilings and doors.
• Architectural interiors would often include large and heavy desks, worktables, machinery, assembly lines or the like, depending upon the particular environment. Lighting, heating and cooling (if any) functions were often centrally controlled.
• privacy for face-to-face or telephone conversations, meetings or other commercial interior activities was difficult to achieve.
• ceiling structures typically do not address issues associated with ceiling structures, such as interchangeability, lighting, acoustical properties and the like.
• architects and designers are beginning to look at various types of new designs for purposes of enhancing acoustical properties, lighting efficiency and aesthetics.
• Numerous types of ceiling structures are known in the prior art which are particularly directed to acoustical properties.
• One well known ceiling structure is the Armstrong drop ceiling, utilizing opaque ceiling shielding elements modularly supported within a T-bar structure. These ceilings are manufactured by Armstrong World Industries, Inc. Such structures have to accommodate ceiling lighting (if desired), HVAC ducts, fire sprinklers and similar environmental and safety systems.
• architects and designers have introduced "open" architecture ceilings that expose structure, even in commercial and office environments.
• Lighting associated with such structures also has the same problems with respect to potential need for change. Also, when ceiling systems are first designed by the designers, architects and engineers, it may be several years before the building is actually commissioned and tenants occupy the building. At that time, the needs of the tenants may be relatively diverse from the designer's original lighting schema. Further, lighting needs may vary for different functions. However, most known ceiling lighting structures are relatively constant with respect to their light intensity, and the diffusion which may be associated with the lighting. It would be advantageous to have means for varying the light intensity, color, texture and diffusion associated with the lighting. Other issues also arise with respect to ceiling structures. For example, safety concerns are of primary importance. Fire protection and other building codes may require materials from which ceiling structures are constructed to be treated with fire retardant or fire resistant materials. In addition, the ceiling structure materials themselves may be constructed of fireproof or fire resistant elements.
• ceilings have weight, bulk and other size parameters which are clearly unnecessary for their desired functionality. Their cost is significant. This cost occurs not only from initial acquisition prices, but also, as a result of their lack of true flexibility, from costs associated with moving or reconfiguring the ceiling systems. Also, in part, additional costs result from the fact that reconfiguration of such ceiling systems often results in wastes of component parts. In this same regard, many component parts of known systems are not reusable when disassembled.
• known ceiling systems for many reasons (including those previously stated herein), do not lend themselves to any type of "rapid" reconfiguration. In fact, they may require a significant amount of work to reconfigure. This work often requires use of trained specialists. Also, reconfiguration of known ceiling systems may involve additional physical wiring or substantial rewiring for their lighting. Different trained specialists may be required when the reconfiguration in any manner involves such electrical or data/communications components. Still further, although these ceiling systems may involve lighting controllable by a workspace user, many environmental functions remain centrally controlled, often in locations substantially remote from the architectural interior being controlled.
• Ceiling systems may be structurally designed by designers, architects and engineers, and initially laid out in a desired format with respect to support, lighting fixtures and other functional accessories.
• these structures which can be characterized as somewhat “permanent” in most buildings (as described in previous paragraphs herein), are designed, the actual occupants may not move into the building for several years.
• HVAC heating, ventilation and air conditioning
• a ceiling system can be characterized as being “delivered” to original occupants in a particular "initial state.” This initial state is defined by not only the physical locations of functional accessories, but also the control relationships among switches, lights and the like. It would be advantageous to provide means for essentially "changing" the relationships in a relatively rapid manner, without requiring physical rewiring or similar activities.
• Jones et al. U.S. Pat No. 3,996,458, issued December 7, 1976, is primarily directed to an illuminated ceiling structure and associated components, with the components being adapted to varying requirements of structure and appearance.

• Balinski U.S. Pat No. 4,034,531, issued July 12, 1977 is directed to a suspended ceiling system having a particular support arrangement.
• the support arrangement is disclosed as overcoming a deficiency in prior art systems, whereby exposure to heat causes T-runners to expand and deform, with ceiling tiles thus falling from the T-runners as a result of the deformation.
• the Balinski ceiling system employs support wires attached to its supporting structure. The support wires hold inverted T-runners, which may employ enlarged upper portions for stiffening the runners.
• An exposed flange provides a decorative surface underneath the T-runners.
• a particular flange disclosed by Balinski includes a longitudinally extending groove on the underneath portion, so as to create a shadow effect.
• Ceiling tiles are supported on the inverted T-runners and may include a cut up portion, so as to enable the bottom surface to be flush with the bottom surface of the exposed flange.
• the inverted ⁇ T-runners are connected to one another through the use of flanges.
• the flanges provide for one end of one inverted T-runner to engage a slot in a second T-runner.
• the inverted T-runners are connected to the decorative flanges through the use of slots within the tops of the decorative flanges, with the slots having a generally triangular cross-section and with the inverted T-runners having their bottom cross members comprising opposing ends formed over the exposed flange.
• the inverted T-runners engage the tops of the exposed flanges in a supporting configuration.
• Balinski also shows each decorative exposed flange as being hollow and comprising a U-shaped member, with opposing ends bent outwardly and upwardly, and then inwardly and outwardly of the extreme end portions. In this matter, engagement is provided by the ends of the inverted T-runner cross members.
• Balinski discloses inverted T-runners supporting ceiling structures.
• Balinski et al. U.S. Pat No. 4,063,391, issued December 20, 1977, shows the use of support runners for suspended grid systems.
• Each support runner includes a spline member.

• Permeating throughout the inventive concepts of the ceiling system 100 are the issues associated with what may be characterized as "anticipatory design" or flexibility. That is, at the time that a designer may complete a structural and functional design for a commercial interior (including not only wall structures, but also locations of ceiling shielding elements, electrical fixtures, data nodes, communication outlets and the like), it may be several years before particular tenants occupy the structure. Between the time of the design completion and the time the particular tenants wish to occupy the structure, the prospective tenants' needs may be substantially different from the designers' anticipatory ideas. However, most commercial interior structures permit little reconfiguration of architectural elements and structure, after completion of an initial design. Reconfiguring a structure for the needs of a particular tenant can be extremely expensive and time consuming.
