Abstract

Abstract A panel for free access to a signal cable and a power cable is installed on the floor of an office room and forms a network of signal cables in an office. The posts of this panel are mounted on the floor. A floor plate is secured to the upper ends of the posts. A rack plate is arranged between the floor plate and the floor, and the rack plate is secured to the posts. The height of the floor plate and the rack plate is adjusted by adjusting the engaging position by rotating a leg to be engaged with the threaded holes of the posts. The floor plates are composed of a plate made of glass, reinforced cement mixed with foamable styrol or an aluminum honeycomb structure. The rack plate is composed of a transparent polypropylene plate. Further, the surface of the floor plate is covered with a surface material such as a carpet. The signal cables are arranged in the space between the floor plates and the rack plates. The power cables are arranged in the space between the rack plates and the floor. Electronic components are mounted on the rack plates. Therefore, the power cables, the signal cables and the other electronic components are completely isolated from each other, and the modification of the layout of office automation equipment can be readily carried out by an authorized person.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 144 words
A panel structure including a plurality of panel sets for mounting adjacent to each other on at least a substantial portion of a surface in a building interior, each panel set comprising: a first panel member having at least one substantially planar rectangular surface of predetermined width and length; a second panel member having a maximum width and length substantially equal to the width and length of the first panel member; and spacer means supporting the first and second panel members for defining a first cable space between the first and second panel members and a second cable space between the building surface and the second panel member, the spacer means including fastening means for removably fastening each first and second panel members to allow access to the first cable space and the second cable space over the entire portion of the building surface.
Claim 2
Dependent Claim 144 words
A panel structure including a plurality of panel sets for mounting adjacent to each other on at least a substantial portion of a surface in a building interior, each panel set comprising: a first panel member having at least one substantially planar rectangular surface of predetermined width and length; a second panel member having a maximum width and length substantially equal to the width and length of the first panel member; and spacer means supporting the first and second panel members for defining a first cable space between the first and second panel members and a second cable space between the building surface and the second panel member, the spacer means including fastening means for removably fastening each first and second panel members to allow access to the first cable space and the second cable space over the entire portion of the building surface.
