- In-floor fittings such as poke-thru fittings, aftersets fittings and preset fittings are installed in concrete floors to provide electrical receptacles and communication/data receptacles (or jacks) at desired locations in buildings. As a result, such fittings may be exposed to water, e.g. during carpet cleaning. It is desirable that such fittings are designed to prevent moisture infiltration, particularly into the area of the fitting that contains the receptacles. In this respect, Underwriters Laboratories (UL) is proposing certification standards which will require such fittings to keep scrub water out of the portion of the fitting that houses the electrical outlet, e.g. the power portion. Scrub water is a soap and water mixture that is typically used when cleaning carpets. Previous in-floor fittings do not provide a means for preventing the scrub water from entering the fitting.
- A cover assembly for use with a floor box of the type having an interior compartment which is accessible through an opening in the surface of the floor includes a bracket and at least one access door. The bracket is connectable to the fitting and defines an access opening that aligns with the floor opening and provides access to the interior compartment of the floor fitting. The access door is connected to the bracket for movement between a closed position at which the door overlies and closes the access opening and an open position at which the access opening is exposed to provide access to interior compartment. The access door includes a cable opening which is sized and configured to allow at least one cable to pass through the door and into the fitting when the door is in its closed position. A seal member is adapted to seal around cables passing through the cable opening when the access door is moved to its closed position.
- The access cover may include a pair of access doors which are pivotally connected to the bracket.

- Referring to the drawings, a
cover assembly 10 is includes abracket 12 and a pair of access doors 14 a, 14 b. Thecover assembly 10 is configured for mounting over an in-floor fitting 16 to provide access thereto from above the floor. In the illustrated embodiment, thecover assembly 10 is show in connection with a preset fitting; however, it will be understood that the access cover could also be adapted for use with other types of fittings, such a afterset fittings, poke-thru fittings, or floor boxes. - By way of background, office buildings require electric power, communication, and computer data services in various combinations at a large number of locations. These needs are often addressed by in-floor cellular raceway systems which have a plurality of parallel cells for carrying service distribution cables including power cables, communication/data cables and the like. The cellular raceway is mounted on a sub-floor and covered with a concrete floor. Access to the under-floor cellular raceway is obtained through preset fittings that are mounted on the raceways at desired locations before the concrete floor is poured. As can be seen in FIG. 1, the
preset fitting 16 defines a hollowinterior compartment 20 that is interconnected with the raceway cells to provide access to the services cables that are carried in cells. A removable mud cap (not shown) on the top of the preset fitting 16 prevents concrete from entering the interior compartment when thefloor 18 is poured. After the concrete floor has hardened, the concrete above the mud cap is broken away and the mud cap is removed to provide access to theinterior 20 of thefitting 16 through an opening 21 in thesurface 22 of thefloor 18. - The in-
floor fitting 16 is adapted to supportreceptacles 26, such as electrical receptacles and/or communication/data receptacles or jacks (not shown). Source cables (not shown) are routed into thefitting 16 from the raceway where they are interconnected with the receptacles. The receptacles present outlets (or connection terminals), which are accessible from above thefloor 18 through the floor opening 20. - The
cover assembly 10 is configured for mounting on the floor fitting 16 to close off the floor opening 20 and provide access to the fitting. For this purpose, thebracket 12 includes acentral portion 28, which is sized for insertion into the floor opening 20. Although the floor opening and the bracket are illustrated as being generally rectangular, it will be appreciated that they could be circular, for example. Thebracket 12 also includes an upper, outwardly extending flange or apron 30. Theflange 30 overlies thefloor surface 22 around the opening 21 to vertically support thebracket 12 within thefitting 16. Thecentral portion 28 is generally rectangular and it protrudes downwardly from theflange 30. Fasteners 32 (one shown) extend through theapertures 34 in the corners of thebracket 12 and thread intoreciprocal apertures 36 in thefitting 16 to secure the bracket to the fitting. A bead of sealant (not shown), such as silicon, may be applied around the perimeter of the underside of theflange 30 prior to installation of thebracket 12 to seal against water infiltration between theflange 30 and thefloor surface 22. Alternatively, a compressible foam gasket (now shown) may be interposed between theflange 30 and thefloor surface 22. - The
bracket 12 is preferably constructed from a durable material such as cast aluminum, brass, or molded plastic. Thebracket 12 includes a central access opening 38, which aligns with the floor opening 21 to provide access to the in-floor fitting 16. The access opening 38 is divided into a first portion 40 a and asecond portion 40 b. A first access door 14 a is associated with the first portion 40 a of the opening 38 and is pivotally connected to thebracket 12 for movement between a first or closed position (see FIG. 5) and a second or open position (see FIG. 3). When the first access door 14 a is at its closed position (see FIG. 5), it is generally flush and parallel with thefloor surface 22. At this position, the first access door 14 a overlies and blocks the first portion 40 a of the opening 38. When the first access door 14 a is at its second position (see FIG. 3), it is generally perpendicular to thefloor surface 22 and the first portion 40 a of theopening 38 is exposed to provide access to theinterior compartment 20 of the fitting. Similarly, the second access door 14 b is movable between a closed position (see FIG. 5) overlying the access openingsecond portion 40 b and an open position (see FIG. 3) at which the access openingsecond portion 40 b is exposed. - Each of the access doors14 a, 14 b includes an outer, pivot
end 44 and an inner,free end 46. The pivot end 44 carries a pair of outwardly extending pivot or hinge pins 48. Thepins 48 extend from opposite sides of the door and are positioned and configured to engage in reciprocalhorizontal slots 50 formed on opposite sides of the access opening 38 in thebracket 12. As can be seen in FIG. 1, theslots 50 run substantially the entire length of the access opening 38 and are defined by respective upper andlower walls opposed slots 50 is shown in the illustrated embodiment, it will be appreciated that a separate pair of opposed slots could be provided for each of the doors 14 a, 14 b. - Two pairs of
opposed cut outs top wall 52 on the opposite sides of the access opening 38 to allow the doors 14 a, 14 b to be removed from and connected to thebracket 12. The manner in which the doors 14 a, 14 b are connected to the bracket can best be understood by referring to FIG. 2, which illustrates the second door 14 b being installed into the flange. Theaccess door 14 is connected to thetrim bracket 12 by sliding its pivot pins 48 downwardly through therespective cut outs 56 b and into theslots 50. Once thepins 48 are positioned in theslots 50, thepivot end 44 of the door is slid outwardly until the pins seat in the outer ends of theslots 50. With the door 14 b in this position, itsfree end 46 may be rotated between its open and closed positions. As will be appreciated, the first access door 14 a is connected to the flange in the same manner. - Each of the doors14 a, 14 b includes a cut-out
portion 60 in itsfree end 46. When the doors are moved to their closed position, the cut-outportions 60 define a reduced-size cable opening 62 which serves as a cable egress between the doors 14 a, 14 b and into the fitting 16. Thecable opening 62 is sized such that at least onecable 63, and preferably a plurality of cables, can be routed between the doors 14 a, 14 b and into the fitting 16. -
Seal members 68 carried by the doors 14 a, 14 b are adapted to seal theopening 62 when the doors are closed. Each seal member includes abody portion 70 which underlies the respective access door and acompressible portion 72 which is positioned in thecutout portion 60 of a respective door. Theseal members 68 are connected to a respective door by adhesive, which may be in the form of an adhesive foam tape that is laminated on the back of the seal members to bond them to the doors. Theseal member 68 is formed of an extruded foam gasket material and thecompressible portion 72 may be formed by shaping the material into a bulb or tube, as is shown. Thecompressible portions 72 of theseal members 68 are configured to sealingly compress around thecables 63 as the doors are moved to their closed position. (See FIGS. 4 and 5) When no cables are present in theopening 62, thecompressible portions 72 of theseal members 68 abut one another to seal theopening 62. (See FIG. 7). Thebody portion 70 of theseal members 68 may include acentral opening 71. Thecentral opening 71 aligns with arecess 73 on the bottom face of a respective access door 14 a, 14 b when theseal member 68 is installed on the door. Theopening 71 and therecess 73 allow the door to be grasped more firmly with one's fingers during operation and installation. - Each of the access doors14 a, 14 b further carries an
egress cover 74 which is slidably connected to the door for movement between a closed or extended position (see FIG. 6), an intermediate or neutral position (see FIG. 8) and an open retracted position (see FIG. 7). When theegress cover 74 is at its closed position, it overlies the cut-outportion 60 of a respective access door. (See FIG. 6). When theegress cover 74 is at its open position, the cut-outportion 60 of the respective access door is exposed. (See FIG. FIGS. 5 and 7). When theegress door 74 is at its neutral position, opposedtabs 76 formed on itsside walls 82 align with the respective cut-outs top walls 52 to allow the access door 14 a, 14 b to rotate between its open and closed positions. (See FIG. 8). When an access door 14 a, 14 b is closed and itsegress cover 74 is moved to either its open or closed position, thetabs 76 on the egress cover are captured within theslots 50, thereby retaining the access door in its closed position. - Referring to FIG. 1, each egress cover includes a top wall80 and a pair of opposed, downwardly extending
side walls 82.Tabs 86 extend inwardly from the side walls 84 and are configured to engage inreciprocal slots 88 formed on the side walls of the access doors 14 a, 14 b. Theslots 88 andtabs 86 engage with each other to allow the egress cover to slidably move relative to the access door. Theegress cover 74 is preferably made from plastic and is configured to snap into place on theaccess door 14. In particular, theegress cover 74 is connected to theaccess door 14 by sliding itsside walls 82 downwardly over the access cover. As thecover 74 moves downwardly, thetabs 86 engage against the access door and bias the side walls 84 of theegress cover 74 outwardly. Theegress cover 74 is moved downwardly until thetabs 86 extend below the top walls 90 of theslots 88, at which time they snap into place in theslots 88, thereby securing theegress cover 74 to the access door. Slots 92 in the top walls 80 of the egress covers 74 mate withupstanding tabs 94 formed on the doors 14 a, 14 b to limit travel of the egress covers 74 on the doors 14 a, 14 b in their closed direction. - The access doors14 a, 14 b are constructed of a durable material such as cast aluminum, brass, or molded plastic. Preferably, the doors are made from the same material that is used to construct the
bracket 12. As can be seen in FIG. 1, the doors 14 a, 14 b may include recessedportions 100 in their upper faces. Finish floor material, such as carpet or tile, may be installed in the recessedportions 100 to match thecover assembly 100 to the surrounding floor surface. - Upwardly extending
protrusions 96 are formed on opposite sides of thecentral opening 38 at the junction of its first andsecond portions 40 a, 40 b. Theprotrusions 96 engage against thecompressible portions 72 of theseal members 68 when the doors 14 a, 14 b are in their closed positions to bias the doors outwardly, e.g., towards the distal ends of theslots 50. As can be seen in FIG. 1, theprotrusions 96 are gradually tapered such that they are narrower at their top end than at their bottom end. - FIGS. 9 and 10 illustrate a flangeless bracket112. The flangeless bracket 112 is identical to the
bracket 12 of FIG. 1, except that it does not include thetrim flange 30. In this respect, the bracket 112 consists entirely of the bracketcentral portion 28 which has the same general construction of the central portion of thebracket 12 shown in FIG. 1. As can be seen in FIGS. 9 and 10, thecentral portion 28 of the bracket is generally rectangular and is sized for insertion into thefloor opening 21. Thecentral portion 28 includes a pair ofopposed side walls 102 and a pair ofopposed end walls 104.Bottom walls 106 extend inwardly from the bottom edges of the side and endwalls bottom walls 106 engage against the bottoms of the access doors 14 a, 14 b to support them against downward movement relative to the bracket. A raisedlip 108 formed along the inner edges of the bottom walls engages against theseal members 68 to seal against water infiltration therebetween. - Since there is no
flange 30 in the flangeless bracket 112, support screws 116 are used to support the bracket 112 within the fitting 16. The support screws 116 thread into theapertures 36 in the corners of the fitting. The support screws 116 carry support brackets 118 at their upper ends which engage against the bottom of the flange 112 to support it vertically within the fitting 16. As will be appreciated, the height of the bracket 112 relative to the fitting 16 is controlled by how far the support screws 116 are threaded into the fitting. Hold downscrews 120 extend through the bracket and thread into apertures 124 in the tops of the support screws 116 to secure the bracket 112 to the fitting 16. - FIGS.11-14 illustrate an embodiment of the cover assembly, which is adapted for use with movable partition furniture. This embodiment is similar to the embodiment of FIG. 1, except that one or both of the access doors is modified so it can be connected to a flexible partition feed conduit for routing wiring between the fitting and a piece of movable partition furniture (not shown). In this respect, the partition
feed access door 314 includes acentral opening 316 sized to receive a liquidtight fitting 318, such as an elbow fitting. One end of the fitting 318 includes a threadedportion 320, which is sized for insertion into theopening 316 in theaccess door 314. Anannular gasket 322 is interposed between theaccess door 314 and aradial flange 322 on the fitting 318. The gasket is compressed between theflange 322 and thedoor 316 to seal around theopening 316. Anut 324 threads onto the fitting 318 from the bottom side of thedoor 316 to secure the fitting to the door. The other end of the fitting has aconnector 326 adapted for interconnection with awiring conduit 328. Theconduit 328 extends between the fitting 318 and a piece of partition furniture (not shown) so that cables can be routed between the in-floor fitting 16 and the partition furniture. Once theconduit 328 is attached to theaccess door 314 and wired, the access door is connected to theflange 12 in the manner described above. Theaccess door 316 can be secured to the in-floor fitting 16 byscrews 332 that extend through thedoor 316 and thread into reciprocal threaded apertures in the fitting 16. In the illustrated embodiment, the threaded apertures are formed in abarrier 334 that is used to separate the power portion of the fitting from the data/communications portion of the fitting. Two of thepartition feed doors 314 can be installed in the flange. Alternatively, (as is shown in FIG. 14), one of thepartition feed doors 314 can be used in combination with anaccess door 14 of the type shown in FIG. 1. - While particular elements, embodiments and applications of the present invention have been shown and described, it will be understood, of course, that the invention is not limited thereto since modifications may be made by those skilled in the art, particularly in light of the foregoing teachings. It is therefore contemplated by the appended claims to cover such modifications as incorporate those features which come within the spirit and scope of the invention.
