## Background
1. Field of the Invention

The invention relates generally to office panel systems and, in particular, to connecting arrangements for connecting remanufactured office panels to new modern office panels.

2. Description of the Prior Art

Office panel systems are currently manufactured by a number of different companies, such as, for example, Teknion Furniture Systems Inc., located in Downview, Canada; Steelcase Inc., located in Grand Rapids, Mich.; and Haworth, Inc., located in Holland, Mich.. Many existing systems are worn from long use but can be remanufactured to look substantially new. Remanufactured office panels and auxiliary equipment for use therewith are substantially less expensive than new panels and new auxiliary equipment which permits a company to install a new office panel system at a substantially lower cost. It also allows a company which owns an office panel system to have at least a portion of the system remanufactured for reuse instead of completely replacing it.

A problem which exists with the older office panel systems is that the panels are not designed to accommodate today's electric wiring and communication cabling requirements. The new office panel systems, such as are disclosed in U.S. Pat. Nos. 5,214,890; 5,277,005; and 5,277,007 owned by Teknion Furniture Systems, Inc., meet today's wiring and cabling requirements. Additionally, the new office panel systems provide wiring and cabling raceways at desk top height for easy access to plugs for electric power and communication cabling. Therefore, companies can purchase new Teknion panels for use with remanufactured panels.

The invention is an arrangement for connecting panels in office panel systems. The connection of the end of one panel to the face of a second panel may be located at any point along the length of the second panel intermediate the ends of the second panel. The invention has particular application in connecting used panels manufactured by Steelcase and Haworth to panels such as those manufactured by Teknion. This results in an office panel system having remanufactured panels to reduce the cost of the system and having Teknion panels to provide state of the art wiring and cabling capabilities. The arrangement may be used to connect office panels made by manufacturers other than Steelcase, Haworth and Teknion at locations intermediate the ends of the panels.
