Abstract
A flush-mounted, multi-service floor outlet, gives economic supply of flush-fitting power and electronic jacks, such as Category 5 data jacks, within existing office towers having poured concrete floors, as original equipment, or by restro-fit or in relocating such services, while maintaining effective fire separation between the repective floors of the building. A unitary, longitudinally compartmented cylindrical metal housing is located in penetrating relation through an existing concrete floor, and the power, voice and data connections are routed through the ceiling space of the underlying room, the conduits for which are threaded into a base portion of the housing. The outlet housing provides a nominal fit within a standard sized hole drilled through the concrete floor to render the installation substantially fireproof. A top flange, and removable bottom flange such as a nut complete the fireproofing and secure the housing in place. The compartment partitions are withdrawable to facilitate installation and servicing. The substantially planar top face of the outlet fits effectively flush with the usual carpet floor covering.
Description
-MULTI-SERVIC'E FLOOR ~TLET
FIELD OF THE INVENTION
This invention is directed to a f'oor outlet for lnstallation through a concrete floor, to provide electrical power and voice/data Jack access.
BACXGROUND TO THE INVENTION
Modern office space ls frequentiy located wlthin hlgh rise buildinqs having existing concrete floors.
The floor plan for an office is rarely immutakle, so that the 10 location of services such as electrlcal power, voice and data connectlons requires a hlgh degree of flexibility. Flre codes frequently requlre that floor-to-floor lnterconnection shall be closely restricted, while electrical wirlng codes usually regulre the provision of isclated electrical services.
Many bullding owners and/or tenants require enclosed electrical and communlcations wlring ln celling spaces below. One prlor art approach to meet the problems imposed by these strlct~res h~s been the use of s~uare, recessable flush outlet housinqs.
A major drawback wlth this approach is the need to saw cut an ~0 oversized s~uare hole into the concrete floor, and to chisel out to an approprlate depth a recess for housing the outle~.
It is then usually necessary to secure the outlet housing ln the floor, and to patch, by cementing or grouting the outlet base ln place. Th~s can lmperll the lntegrity of the floor, and is usually unacceptable to the structural engineer CA 022l544l l997-09-l5 who is responslble for the buildln~.
In an exl~tlng offlce, adoptlon of thi procedur~ often ~auses unintended, highly undesireable local damage to t~e area carpeting.
Furthermore, the method is labour-intenslve, structurally damaging, and ~lakes difflcult the succeedlng step of lnEtallin~
the a6soclated condult.
Another prlor art approach is to lnstal a throu~h-the-~lo~
outlet, such as the "Walkertap" ~trademark), referred to commercially as the " 1503 Eerles flush poke-through" havlng a cyllndrical pot that is lnstalled through the floor. This service outlet, whlch is nominally "flush", has a domed top plate above which proJects the molded housings of the two voice/data jack outlets.
These voice jack outlets are serviced by plgtail connections that hang down within open recesses below the top plate, and the connections pass outwardly through apertures in the wall of the cylindrical pot, thereby providing a pair of vulnerable paths that requlre to be packed with flre-proof material, in 20 attempting to meet local fire regulations. These pig-tail connection~ are serviced wlthin the underlying ceiling space, and in the absence of an enclosure and provision for protection such as a conduit, are vulnerable to unautherized access.
The electrlcal service occupies the pot, and connects by way of an intermediate conduit with a Junction box accessible only ln the underlying celllny ~pace.
Typlcally, this hlgh-cost lnstallation provides a slightly domed outlet cover having a pair of flush power outlets and a pair o~ elevated volce/data jacks, which constitute a trippng hazard ln open and multi-use areas.
SUMMARY OF THE INVENTION
The present invention provides a unitary, flush mounted, totally enclosed houslng for through-floor multi-service installation.
10 The subject servlce housing has a substantially planar top flange secured to a cylindrical housing for insertion ln close-fittlng relation within a cylindrical bore of predetermined standard size.
The housing includes provision for connection of a plurality of service conduits in threaded relation with the lower end of the housing.
The housing includes interior isolating partition means, to enable physical and electrical isolation of an electrical power service therein.
20 In a preferred embodiment lnterlor partltion means are removable, to facilitate manual access to the interior of the housing. A plurality of interior partitions may be provlded which are removable, for enhanced manual access. The partition means may be of flberglaEs or other electrical lnsulating material. Where internal clearances are adequate and no possibility of Ehort-clrcultln~ or un~e&iLed ~psclt~n~e effectE exiEts, and where safety co~es are not violated, the use of metal part1tions is contemplated.
The subJect service housing ~ay have housing securing means, in use to secure the housing in lnstalled relation within an aperture.
The hou~in~ ~eLu~lng me~n~ m~y c~mpEi~e a top flan~e, and a locknut threadedly attached to the lower exterlor por-tlon of the houslng, to engage the floor lower surface. The locknut lO also serves to complete the fla~eprocfing of the installatlon.
An alternative securing means that is contemplated may comprise a grubscrew or capscrew, the polnt of which extendE outwardly from wlthln the houslng, ln use to engage the interior of the bore within which the housing is inserted to hold the housing secured therein.
The su~ect service may include removable cap means, to provide access from above to the inte.ior vf the housing. The removable cap means may comprise an outer cover, in securing relation with a plurality of plug-accessed electrical 20 connection units.
The removable cap mean~ may include a flange portion of the pot, by means of which the pot is supported in its position by the surrounding floor.
Th~ rem~vable cap mean~ are preferably ~ecured by way of screws that are recessed in flush relation with the respective cover top surface, and engage threaded aperture~ of the hou~in~.
The housing may lnclude threaded recesses in a lower portion of the housing, to receive condult connectors in screwed se~ured relation therein. The conduit connectors, in turn, receive electrical conduit in connecting relation therewith. The houslng may lnclude a unit~ry bottom portlon having a pluraIlty of threaded recesses for the aforesaid conduit connectors.
