Definitions

  • the present invention relates to raised floor systems and more particularly to a cable support assembly for use in connection with a raised floor system.
  • Cable trays in general have been used in power stations and large industrial plants for a number of years to support and route various cables through the plants rather than placing these cables inside a conduit.
  • These cable trays are normally supported from a wall or a ceiling at levels which are above a person's head in order to avoid obstructing normal floor space.
  • An alternative to the elevated cable tray has been elevated distribution ducts which are also normally mounted from a wall or a ceiling at elevations so as not to interfere with a person standing on the floor and thus, again, conserve floor space.
  • Prior art cable trays have been developed to eliminate some ofthe problems associated with the routing of cables beneath the raised panel floor. Most prior art cable trays are simply placed on the concrete subfloor. Other cable tray designs are suspended from the structure which supports the removable panels ofthe raised panel floor. These prior art designs are normally suspended between the raised panel floor and the concrete subfloor and provide an organized route for the various cables to travel in order to interconnect the numerous pieces of electronic equipment placed on the raised panel floor. While the introduction of these prior art cable trays has significantly reduced the entanglement and moisture problems associated with the concrete subfioors, they are not without their problems. As the number of pieces of electronic equipment being placed in a single room increases so does the number of electrical cables. Consequently the number of electrical cables which are being placed within the prior art cable trays is also increasing.
