Description
    BACKGROUND OF THE INVENTION
  • [0001]
    The present invention relates to desking systems for use in business situations requiring high density data and voice communications and, in particular, such a desking system providing high functionality both in use and for maintenance and service, such as are required in stock, money and commodities exchange functions.
  • [0002]
    A class of tables or workstations has evolved that are particularly adapted for use as so-called “trading tables” where traders operating in the stock, currency, or commodities markets need rapid access to large volumes of computer data and voice transmissions. Such tables must typically hold, for rapid convenient access, keyboards, CRTs or flat panel screens, and telephones or other data and voice communications hardware. These tables typically also include a space beneath the table top for the computer hard drives and other data and communication hardware. The tables have typically developed to be specified in linear runs and modular table construction has facilitated the joining of multiple tables in many different arrangements. In addition to the active data and voice communications hardware, the tables also may be adapted to provide screen panel dividers when assembled in face-to-face relation.
  • [0003]
    In addition to the functional requirements for regular use, it is important that any trading table construction provide support and organization for data and voice cabling, connection terminals, power supply wires and cables and other peripheral hardware in a manner that keeps it out of sight for aesthetic purposes, yet allows ready access thereto for maintenance, repair, or replacement.
