Abstract
Abstract The specification discloses a movable room divider panel system in which the divider panels include raceways with removable covers and fixed electrical outlet boxes which are proportional in length from end to end to the width of their respective panels from edge to edge. Outlet boxes in adjacent panels are joined by flexible conduits enclosing electrical wiring, there being mating connectors on the ends of the flexible conduits and at the ends of the outlet boxes.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
A movable room divider panel system comprising: at least two movable panels of differing widths from one end edge to the other, each including an accessible raceway therethrough and a readily releasably mounted cover over said raceway whereby said cover can be removed to allow access to said raceway; an outlet box positioned within each said raceway having at least one electrical outlet; said outlet box and said raceway having relative dimensions which allow communication wiring to be placed within said raceway in addition to said outlet box; at least one electrical connector at each end of said electrical outlet; electrical connector at each end of said electrical outlet; electrical wiring and flexible conduit enclosing said electrical wiring and having an electrical connector at each end of said conduit capable of matingly engaging said electrical connectors in said outlet boxes whereby said flexible conduit can be located within said raceways and used to electrically connect said outlet boxes in said two panels; said outlet boxes being of differing lengths, each being proportional in length to said width of its respective panel whereby the flexible conduit connectors employed to join electrical outlet boxes in adjacent panels can be of a uniform length regardless of the width of the adjacent panels.
Claim 2
Dependent Claim
209 words
A movable room divider panel system comprising: at least two movable panels of differing widths from one end edge to the other, each including an accessible raceway therethrough and a readily releasably mounted cover over said raceway whereby said cover can be removed to allow access to said raceway; an outlet box positioned within each said raceway having at least one electrical outlet; said outlet box and said raceway having relative dimensions which allow communication wiring to be placed within said raceway in addition to said outlet box; at least one electrical connector at each end of said electrical outlet; electrical connector at each end of said electrical outlet; electrical wiring and flexible conduit enclosing said electrical wiring and having an electrical connector at each end of said conduit capable of matingly engaging said electrical connectors in said outlet boxes whereby said flexible conduit can be located within said raceways and used to electrically connect said outlet boxes in said two panels; said outlet boxes being of differing lengths, each being proportional in length to said width of its respective panel whereby the flexible conduit connectors employed to join electrical outlet boxes in adjacent panels can be of a uniform length regardless of the width of the adjacent panels.
Claim 3
Dependent Claim
48 words
The movable room divider panel system of claim 1 in which at least two connectors are located at each end of each said electrical outlet box whereby said panels and said flexible connectors can be arranged to provide for power going to three or more adjacently joined panels.
Claim 4
Dependent Claim
48 words
The movable room divider panel system of claim 1 in which at least two connectors are located at each end of each said electrical outlet box whereby said panels and said flexible connectors can be arranged to provide for power going to three or more adjacently joined panels.
