Abstract
Abstract An interior panel according to the present invention comprises a plurality of support units fixedly arranged on a floor slab, a panel member supported by the support units so as to be located over the slab surface at a predetermined distance therefrom, and a cable separator supported by the support units and dividing the space between the panel member and the slab surface into upper and lower space sections. The cable separator is in the form of a plate with a stepped surface portion at the peripheral edge portion thereof, and can be supported on the support units either in a first position in which the stepped portion faces upward or in a second position in which the stepped portion faces downward. Cables and electric devices in a signal transmission system are arranged in the upper space section defined by the cable separator, and power supply-system cables and devices in the lower space section.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
249 words
An interior panel which overlies the surface of a slab defining the inside space of a room to form the interior surface of the room so that a space to permit installation of signal transmission cables, power cables, and electric devices is formed between the interior panel and the slab surface, comprising: a panel member; a cable separator; and a plurality of support means fixedly arranged on the slab surface, said support means supporting the panel member at a predetermined distance from the slab surface and supporting the cable separator interposed between the panel member and the slab surface, each said support means comprising a supporting portion contactingly supporting said cable separator and disposed such that the distance between the inside face of the panel member and the supporting portion is substantially equal to the distance between the supporting portion and the slab, the cable seaparator having the form of a plate dividing the space between the panel member and the slab into a first space between the panel member and the cable separator and a second space between the cable separator and the slab, the cable separator having a stepped surface at the peripheral edge portion, the support means supporting the cable separator by contact between the supporting portion and the stepped surface, said supporting portion and said stepped surface being configured for removal of the cable separator, inversion and replacement thereof, and continued support of said stepped surface by said supporting portion following said inversion and replacement.
Claim 2
Dependent Claim

Claim 6
Dependent Claim
19 words
An interior panel as claimed in claim 4, wherein a plurality of holes are formed in said cable separator.
Claim 7
Dependent Claim
18 words
The interior panel according to claim 1, wherein both the panel member and the cable separator are square.
Claim 8
Dependent Claim
82 words
The interior panel according to claim 4, wherein each support means includes a plate-like pedestal fixed on the slab surface, a bolt portion set up on the pedestal, a first supporting plate screwed on the end of the bolt portion to support each corresponding corner portion of the panel member, and a second supporting plate screwed on the central portion of the bolt portion to support each corresponding corner portion of the cable separator, said supporting portion comprising said second supporting plate.
Claim 9
Dependent Claim
84 words
