ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to a wall panel system, and in particular, to an improved wall panel, components therefore and a method for making the wall panel.
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 two such work space management systems: the ACTION OFFICE® system and the ETHOSPACE® system. Often, wall panels arranged in such systems include an internal frame with a sheet of wall board or comparable material attached to the side of the frame. Typically, the frame is made from roll-formed or extruded metal, with the wall board adhesively secured to the side of the metal frame members. Each side of the wall panel usually is covered with a fabric that is either bonded to the frame, or attached with an elastic band, so as to provide an aesthetically pleasing appearance to the user.
Adjacent wall panels in the system typically are connected to one another with a variety of connector assemblies. For example, wall panels placed end-to-end commonly are connected to each other, while wall panels oriented perpendicular to each other in a two-way, three-way or four-way configuration typically are connected to a corner post located at the junction of the intersecting panels. Typically, a cover is attached to those sides of the corner post not connected to a wall panel so as to provide an aesthetically pleasing surface that matches the surface of the adjacent panels.
Wall panels often are provided with wire management capabilities, typically including horizontal wire channels positioned at the top and bottom of the panel. Wall panels may also include vertical channels, typically formed by the vertical frame members, that extend between the top and bottom of the panel. Typically, wall panels having a horizontal channel at the top of the panel also provide a top cap to cover the channel. When a corner post is interposed between panels, a cap also is installed on top of the corner post to provide a continuous, unbroken line across the top of a system of wall panels.
Wall panels may also include power distribution systems, whereby the wall panels can be electrically connected so as to provide the user with access to power in each work space created by the system of wall panels.
SUMMARY OF THE INVENTION
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. Each of the frame members includes a core member and a pair of sidewall members attached to opposite sides of the core member. The sheetlike wall members, preferably made of fiberboard, have an inner surface attached to the side walls 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 a preferred embodiment, the sidewall members 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 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 a preferred 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 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 core members, a partition member spaced apart from the inner core surface of the vertical core 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 of the inner surfaces of the wall members between the upper and lower frame members. The other wall member 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. 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 hook member on the edge portion of the side wall.
In another aspect of the invention, wall panels placed end-to-end are attached using an upper and lower draw block that engage hanger brackets attached to the ends of the wall panels. A draw rod operably engages the draw blocks which pull the hanger brackets and corresponding panels together.
In yet another aspect of the invention, a corner post is provided for connecting two or more panels at 90°. The corner post includes an elongated tube having a pair of inwardly facing channels formed on each side of the tube. A plate member is secured inside each end of the tube; the upper plate having a threaded hole in the middle of the plate.
The corner post is provided with a height adjustable cap which includes a post member and a cover member supported by the post member. The post member threadably engages the hole in the upper plate and can be rotated to adjust the height of the cover. In this way, the cover can be raised or lowered to provide a smooth transition between adjacent wall panel top caps.
In another aspect of the invention, an outwardly facing groove is formed in each corner of the tube. A cover has diagonally oriented beaded portions. The cover is attached to the corne
