| Abstract | A portable partition panel is provided for open office plans, and the like,
and includes a panel frame and removable cover panels that removably
attach thereto. Clips on the cover panels releasably engage side frame
segments of the panel frame, and hooks on the bottom of the panel frame
releasingly engage mating apertures on the cover panel to form a
detachable interconnection therebetween. A top cap includes a catch which
pulls the cover panels against the panel frame as the cap is installed to
assist in securely, yet removably attaching the cover panels to the panel
frame. Connectors on the cover panels can be removed and reinstalled, so
that the cover panels can be installed in a second orientation to hide
mars upholstery tears, and the like. Also, the panel frame includes an
upwardly open channel for receiving articles such as wires in a raceway.
The upper segment of the panel frame further includes a reduced
cross-section that allows cables to be routed from the utility channel
into the interior of the partition panel. Also, the side clips have a
unique design which causes them to remain on the cover panel during
removal and also controls the releasing motion of the panels. |

BACKGROUND OF THE INVENTION
The present invention relates to furnishings for open offices, and the like and in particular to movable room divider panels or partitions of the type having frame and removable cover panels.
Room divider systems are particularly popular in modern offices, since they allow large areas to be aesthetically and economically subdivided for maximum worker productivity. However, despite their flexibility, further improvements are desired.
For example, most existing panel systems do not allow the exterior surfaces of the panels to be removed and replaced without significant effort and several tools. Some attempts have been made to solve this problem through the use of removable cover
panels. However, in such systems, the removable cover panels are typically difficult to remove and/or securely reinstall. Also, present retention systems for holding the removable cover panels on their associated frame are not as positive as desired,
thus leading to loose and misaligned cover panels. Further, clips and attachment brackets are often lost or damaged, aggravating the problem of inadequate attachment. Still further, dirty or damaged panels with exposed but only localized damage must be
removed and replaced in order to satisfactorily refurbish an office layout.
Recently, room divider systems have been adapted to include raceways and the like for routing electrical power and telecommunication cables therethrough. Improvements in this aspect of portable partition panels is also desired. For one, the
raceways provided for laying in cables are difficult to access, and often require some disassembly of panels. Other systems require that the cables be strung or threaded into the raceways. Further, in most systems, it is difficult to separate high
voltage lines such as for dispensing electrical power from low voltage lines such as for telecommunication. This leads to mixed lines resulting in electrical interference therebetween. This potentially also creates maintenance hazards where the wires
are poorly identified.
Thus, a panel system offering increased flexibility in panel placement, attachment, repair, and refurbishing is desired. Further, a system is needed in which high voltage lines are readily accessible and separatable from low voltage lines, while
simultaneously also offering maximum flexibility in cable routing and placement.
SUMMARY OF THE INVENTION
One aspect of the present invention provides a freestanding, portable partition panel including a panel frame having opposing faces and a channel, a removable cap shaped to cover at least a portion of the channel, and at least one removable cover
panel shaped to cover at least a portion of one of the faces of the panel frame. A catch connected with the cap operably engages a part of the cover panel to assist in securely yet removably attaching the cover panel to the panel frame.
Another aspect of the present invention provides a freestanding portable partition panel including a panel frame with at least one face and first and second connectors. Also provided is at least one cover panel shaped to cover the face, the
cover panel having top and bottom portions that are generally symmetrical about a horizontal centerline. The cover panel further includes third and fourth connectors shaped to releasably engage the first and second connectors of the panel frame. The
fourth connector is located adjacent the top portion of the cover panel, but is removable and reattachable adjacent the bottom portion, so that the cover panel can be readily removed from the panel frame and reattached in an inverted orientation to
conceal mars, upholstery tears, and the like.
Yet another aspect of the present invention provides a freestanding portable partition panel including a panel frame having top and bottom frame segments interconnected to create a rigid frame structure having opposite faces and an interior, the
panel frame including a utility raceway positioned either at the top or bottom of the panel frame. The partition panel also includes a removable cover panel for covering a face of the panel frame. The one of the top and bottom segments adjacent the
utility raceway has a channel configured to permit routing utilities in the utility raceway through the channel and into the interior of the panel frame without interfering with the flush attachment of the cover panel to the panel frame. In the
preferred embodiment, the one frame segment is swagged to permit routing utilities from the channel to the interior of the panel frame.
Yet another aspect of the present invention provides a freestanding portable partition panel including a panel frame having opposing side frame segments and opposite faces. Also provided is a removable cover panel shaped to cover one of the
faces, the cover panel including inwardly oriented side flanges disposed adjacent the side frame segments. The partition panel includes spring clips positioned on at least one of the side flanges, with a first barb which engages the side frame segment
and second and third barbs which engages the side flange of the panel frame to interconnect the cover panel and panel frame. The second and third barbs cause the spring clip to pivot thereby assisting in releasing the first barb from the panel frame
without pulling the spring clip off of the cover panel.
Numerous advantages are found in the present invention over prior art. The removable cap and removable panel cover simplify installation, repair, replacement, and refurbishing of panel systems and reduce the need for multiple tools. Further,
the cover panels that are attachable in inverted positions allowing localized mars and damaged panels to be inverted and reused. Still further, the spring clips facilitate cover panel installation and removal by remaining attached to | | |
