Description




BACKGROUND OF THE INVENTION




The present invention relates to office partition panel systems, and in particular to a connector for stacking partitions that provides quick and easy on-site assembly.




The efficient use of building floor space is an ever-growing concern, particularly as building costs continue escalating. Open office plans have been developed to reduce overall officing costs, and generally incorporate large, open floor spaces in buildings that are equipped with modular furniture systems which are readily reconfigurable to accommodate the ever changing needs of a specific user, as well as the divergent requirements of different tenants. One arrangement commonly used for furnishing open plans includes movable or portable partition panels that are detachably interconnected to partition off the open spaces into individual workstations and/or offices. Such partition panels have sufficient structural strength 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.” Such partition panels have an acoustical sound-absorbing configuration to promote a quiet, pleasant work environment.




In an effort to accommodate the changing requirements of the users, “stacking” panel systems have been developed to permit the height of a partition panel to be extended if required for a particular application. Known stacking panel systems may be difficult to install, and further, the stacking panel may interfere with the routing of communications and/or power lines through the partition system. Accordingly, a stacking panel system alleviating the above-identified problems is desired.




SUMMARY OF THE INVENTION




One aspect of the present invention is a partition frame assembly including a lower partition frame. The lower partition frame has at least two elongated lower structural uprights, and the lower partition frame defines an upper edge. The lower partition frame further includes an upwardly-opening utilities channel extending adjacent the upper edge to permit lay-in of utility lines along the upper edge of the lower partition frame. An upper extension frame is positioned above the lower partition frame, and includes at least two elongated upper structural uprights, each of which is in vertical registry with the lower structural uprights. The partition frame includes first and second brackets, each of which rigidly interconnects a selected upper structural upright to a selected lower structural upright. Each bracket has a lower end rigidly interconnected with the selected lower structural upright, and an upper end rigidly interconnected with the selected upper structural upright. Each bracket has an upwardly-opening cut-out therethrough that is positioned in alignment with the utilities channel to permit routing of utility lines along the utilities channel and through the brackets.




Another aspect of the present invention is a partition frame assembly including a lower partition frame including at least two elongated lower structural uprights. The lower partition frame defines an upper edge, and includes an upwardly-opening utilities channel extending adjacent the upper edge to permit lay-in of utilities along the upper edge of the lower partition frame. An upper extension frame is positioned above the lower partition frame, and includes at least two elongated upper structural uprights, each of which is in vertical registry with the lower structural uprights. The partition frame assembly includes a pair of brackets, each of which rigidly interconnects a selected lower structural upright with a selected upper structural upright. Each bracket is generally Y-shaped, and defines an upper portion having a pair of upwardly extending legs with a clearance opening therebetween. Each of the upwardly extending legs is rigidly interconnected with a selected upper structural upright with the clearance opening positioned in alignment with the utilities channel to permit routing of utility lines through each of the brackets. Each Y-shaped bracket has a lower portion rigidly interconnected with a selected one of the lower structural uprights to rigidly interconnect the upper partition frame to the lower partition frame.




Yet another aspect of the present invention is a bracket for rigidly interconnecting an extension panel frame to a base panel frame. The bracket includes an elongated rigid body having a central portion and first connectors on an upper portion adapted to rigidly interconnect to an extension panel frame. The rigid body also has a second connector on a lower portion that is adapted to rigidly interconnect the bracket to a base panel frame. The bracket also includes a catch extending transversely from the central portion of the rigid body. The catch is shaped to engage a base panel frame to support the bracket and permit securing the second connectors to a base panel frame.




Yet another aspect of the present invention is a method of interconnecting an extension panel frame to a lower panel frame of the type having at least one utility line extending within an upwardly-opening utility trough positioned along an upper edge of the lower panel frame. The method includes providing a bracket having a lower portion and an upwardly-opening clearance opening therethrough. The utility line is shifted out of the utility trough, and placed in the clearance opening through the bracket. The clearance opening is aligned with the utility trough, and the utility line is shifted into the utility trough. The bracket is secured to the lower panel frame, and the extension panel is positioned above the lower panel frame. The extension panel is secured to the bracket to interconnect the extension panel frame and the lower panel frame.




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

.




With further reference to

FIGS. 4-6

, bracket


10


includes a clip


29


that is received on the lower edge


30


of cut-out


13


. During installation of bracket


10


, the bracket


10


is inserted into the open upper end


24


of lower post


3


, and the downwardly extending leg


32


of clip


29


engages the lower, horizontal edge


31


of cut-out


23


of post


3


to prevent the bracket


10


from falling into the lower post


3


. An upwardly extending hook-like portion


33


at the lower end


11


of bracket


10


is then shifted outwardly through large opening


34


of connection port


18


. Hook


33


has width that is substantially equal to the width of opening


34


, such that hook


33


fits snuggly against the side edges of opening


34


to prevent side-to-side motion of lower end


11


of bracket


10


. The bracket


10


is then shifted upward slightly, such that the upper edge


36


of opening


34


is received within the gap


35


formed by the hook portion


33


of bracket


10


. Leg


32


of clip


29


has sufficient flexibility to permit downward shifting of bracket


10


during installation, and also biases the bracket


10


upwardly, such that the edge


36


of opening


34


in post


3


remains in the gap


35


formed by hook


33


of bracket


10


. After inserting a pair of brackets


10


into the open upper end


24


of lower post


3


, the extension post


8


is positioned above the post


3


, and shifted downwardly, such that the upper ends


12


of brackets


10


are received in the open lower end


39


of extension post


8


. Bolts


38


are then inserted through the openings


40


of extension posts


8


, and threaded into the threaded openings


37


in the upper end


12


of bracket


10


. It is anticipated that, during assembly, a pair of the extension posts


8


would be interconnected by a structural beam


15


to form the upper extension frame


7


, which would then be installed as a unit on a pair of the lower posts


3


. Utility lines


6


may be installed in the utility channel


5


of the lower partition frame


2


, such that the utility lines


6


are first grasped, and pulled out of the cut-out


23


of post


3


during installation. The brackets


10


are then inserted into the open upper end


24


of post


3


as described above, and the utility lines


6


are then placed in the cut-out


13


of bracket


10


and positioned in alignment with the utility channel


5


formed by the upper utility trough


21


. Alternately, the utility lines


6


may be placed in the cut-out


13


of bracket


10


prior to inserting the bracket


10


into the open upper end


24


of post


3


. The extension post


8


is then installed as described above. Extension posts


8


may include a cut-out


41


at the lower end


39


to provide additional clearance for utility lines


6


. Bracket


10


preferably includes a pair of elongated clearance openings


42


that provide clearance for the hooks


16


of a beam


15


that is positioned directly below the upper utility trough


21


.




As illustrated in

FIG. 7

, in an alternate embodiment, hook


33


includes a tapered, or sloped upper surface


45


that engages the upper edge


36


of opening


34


in sidewall


46


of post


3


. The angled surface


35


ensures that the lower end


11


of the bracket is biased into contact with the sidewall


46


due to the upward force “P” on the bracket


10


generated by the leg


32


of clip


29


.




With reference to

FIG. 8

, clip


29


is formed from a relatively thin spring steel, and has a main body portion


47


, and a pair of U-shaped retainers


48


that secure the clip


29


to the lower edge


30


of cut-out


13


of bracket


10


. Leg


32


extends downwardly at angle relative to the plane formed by bracket


10


, and includes an end portion


49


that extends approximately parallel to the plane of bracket


10


to ensure that the clip


29


does not inadvertently disengage from the lower edge


31


of cut-out


23


of lower post


3


.
