BACKGROUND OF THE INVENTION
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 infloor fittings do not provide a means for preventing the scrub water from entering the fitting.
BRIEF SUMMARY OF THE INVENTION
A cover assembly for use with an in-floor fitting 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. The access doors can be opened to provide access to the inner compartment through the access opening. When the doors are at their closed position, they define a cable opening therebetween. The cable opening is sized to permit at least one cable to pass between the doors and into the interior compartment. At least one of the doors includes a seal member which is adapted to compressibly seal around cables passing through the cable opening. Covers may be connected to the access doors for selectively exposing and covering the cable opening.
