ABSTRACT:
BACKGROUND
The present invention relates generally to a wall panel system, and in particular, to a stackable wall panel system.
Panel systems are commonly used to divide large, open office space into separate work spaces. For example, Herman Miller, Inc., the assignee of the present application, manufacturers and sells three such work space management systems: the ACTION OFFICE® system, the ETHOSPACE® system and the Q™ System. Typically, workspace management systems are comprised of a series of wall panels arranged in various configurations. For example, wall panels can be connected in series in an end-to-end configuration, or they can be arranged around and connected to a corner post in a two-way, three-way or four-way configuration. Often, it is desirable to provide wall panels of differing heights so as to allow the user of the workspace to have flexibility in configuring the workspace. For example, shorter wall panels can be used to ease and promote communication with a user of the workspace, e.g., at a reception area. Conversely, taller wall panels can be used to provide greater privacy for the user.
In other systems, upper wall panels can be arranged above lower wall panels so as to allow the user to reconfigure the workspace. In this way, the height of a wall panel defining in part the workspace can be altered with stackable upper wall panels, rather than removing entirely a lower wall panel and replacing it with a taller or shorter wall panel. Often, however, the addition or removal of stackable upper wall panels can involve complex, multiple parts and require excessive amounts of time and manpower to effect the necessary or desired change.
Moreover, it can be important to provide for the routing of various communication and power lines and other utilities in the office work space environment. Typically, such lines are run internally within the panel system so as to improve the aesthetics of the system and to avoid tampering or inadvertent dislodgment by the workspace user. At the same time, it is desirable to provide access to such lines so as to facilitate repairs to and/or routing of the lines.
SUMMARY
Briefly stated, one aspect of the invention is directed to an improved wall panel. The wall panel includes a rectangular frame, a pair of sheetlike wall members and two thin decorative sheets. The rectangular frame includes two spaced apart, and generally parallel vertical side frame members and spaced apart and generally parallel horizontal lower and upper frame members. The frame members are connected at opposite ends thereof to form the rectangular frame. The sheetlike wall members, preferably made of fiberboard, have an inner surface attached to the side of each frame member. The thin decorative sheets, preferably cloth, cover the outer surface of the wall members on each side of the panel.
In one embodiment, each of the frame members includes a core member and a pair of sidewall members attached to opposite sides of the core member. The sidewall members preferably include a substantially flat leg portion having an inner surface attached to the core member and an outer surface attached to the wall member. The sidewall member includes an edge portion extending laterally outward from the leg portion. Preferably, the edge portion is configured as a C-shaped channel facing inwardly away from the wall panel surface. When the frame members are assembled into a rectangular frame, the edge portions extend around the periphery of the wall panel. The sidewalls, including the edge portions, form a shallow recess on opposite sides of the panel. Each recess has a bottom surface defined by the outer surface of the leg portions. The wall members are received in the recesses on opposite sides of the panel.
In another embodiment of the wall panel, a pair of inner sheetlike wall members are attached to the rectangular frame to form a core assembly. In this embodiment, the frame members are preferably of a one-piece wooden construction. A pair of outer wall members are then attached to the inner wall members of the core assembly. The outer wall members extend outwardly from the periphery of the inner wall members to form a channel between them.
In one aspect of the invention, the core assembly includes at least one locator opening therethrough. The outer wall members each include at least one locator member that is received in the at least one locator opening as the wall members are mounted to the core assembly. The locator members and openings are arranged on the wall members and core assembly, respectively, so that the wall members are centered on the core assembly from side to side. The locator members and openings can also be arranged so as to ensure that the top of the wall member is positioned a predetermined distance from the top of the core assembly, or channel thereon, so as to provide a uniform and continuous line or appearance along the top of a plurality of wall panels arranged in a system of wall panels.
In another aspect of the invention, a thin barrier sheet, or scrim, is disposed between the decorative sheet and the outer surface of the wall member as a fire blocking member. The barrier sheet preferably includes a thin aluminum foil layer laminated to a fiberglass layer.
The wall panel also includes an inner filler member disposed between the wall members. The filler member extends between the upper and lower horizontal frame members. Preferably, the inner surface of the wall members are attached to the filler member.
In one embodiment of the invention, the sidewall members on the upper horizontal frame member extend upwardly from the upper core member to form a horizontal channel running substantially the length of the wall panel. The bottom of the channel is defined by the upper surface of the upper core member and the sides of the channel are defined by the upwardly extending sidewall members. A top cap is releasably secured to the upper frame member to cover the channel.
In another embodiment, a channel member is attached to the upper horizontal frame member in the space formed between the outer wall members to further define a horizontal channel. A top cap is secured to the channel member to cover the channel.
In one aspect of the invention, the wall panel also includes at least one vertical channel communicating with the upper horizontal channel and a bottom portion of the wall panel. Preferably, the vertical channel is defined by an inner surface of one of the vertical frame members, a partition member spaced apart from the inner surface of the vertical member and the inner surface of the wall member. Preferably, the partition member extends between the inner surfaces of the opposing wall members and is attached to at least one of the wall members. The partition member also extends substantially between the upper and lower frame members.
In another aspect of the invention, a power distribution system is provided at the base of the wall panel. The power distribution system includes a power distribution server, including a harness and a module receptacle, which is attached to a bottom of the lower frame member. The power distribution system is adapted to be electrically connected with power distribution systems located in adjacent panels. In addition, an outlet box is attached to one or more of the wall members between the upper and lower frame members. At least one of the wall members has an opening provided to allow access to the outlet box. The outlet box is electrically connected to the power distribution system with an electrical conduit disposed in the vertical channel.
In another aspect of the invention, a plastic strip is attached to the decorative sheet at each of its edges. The strip includes a first hook member that is adapted to engage the edge portion of the sidewall member of the frame members in one embodiment of the wall panel. Preferably, the strip also includes a second hook member that is adapted to receive a tool member which can be used to stretch the decorative sheet between opposing frame members while simultaneously disposing the first h
