  • Publication number: 20140262417
    Abstract: An electrical box cover assembly includes a base having a central opening and a collar encircling the central opening. A sleeve slides through the collar and is adjusted to a selected position by manually moving the sleeve and then locking the sleeve in place by a locking device. An expandable locking device contacts an inner surface of the sleeve to lock the position of the sleeve with respect to the base. In one embodiment, the inner surface of the sleeve has at least one channel that extends in an axial direction with respect to an axial passage in the sleeve. The locking device expands outwardly to engage the opposing surfaces of the channel to prevent axial movement of the sleeve. A divider plate can be coupled to the sleeve to move with the sleeve and divide the electrical box into separate compartments. The divider can have fixed plate attached to the electrical box and movable plate coupled to the movable sleeve that slide on the fixed plate.

  • Patent number: 8714506
    Abstract: A mounting assembly and method are provided for mounting an electrical fixture to a ceiling structure. The mounting assembly includes a mounting plate and a cover plate overlying the mounting plate. The mounting plate includes a plurality of strengthening ribs and a plurality of fastener holes for receiving fasteners to mount the mounting plate directly to the ceiling support structure. The mounting plate has a dimension to overlie the support structure and a portion of an electrical box mounted adjacent the support structure to define an open area of the electrical box. Mounting bolts extend downwardly from the mounting plate for attaching to a bracket which supports an electrical fixture such as a ceiling fan. The mounting bolts and the bracket supporting the electrical fixture are cantilevered with respect to the ceiling support. The mounting assembly can be used as a retrofit and mounted over an existing ceiling substrate with screws that can pass through the ceiling substrate into the ceiling support.
