TITLE OF THE INVENTION

ELECTRICAL FITTINGS WITH INTEGRAL COVER PLATE AND METHOD OF USE THEREOF

BACKGROUND OF THE INVENTION

Technical Field of the Invention

The present invention relates generally to electrical fittings or fixtures, and more specifically to electrical fittings or fixtures having an integral cover plate.

Description of Related Art

During construction of buildings, both commercial and residential, it is common to provide an electrical wall box for receiving an electrical fitting, such as, an outlet or a switch. The electrical wall box is typically secured to

WO 2013/165885

PCT/US2013/038619 the side of a vertical stud. Once the wall box is installed, wallboard is typically installed over the studs and an opening is cut in the wallboard in order to pass the electrical fitting through the wallboard. Often, the opening is cut prior to installation of the wall box and the wall box is secured to align with the 5 opening. Electrical wiring from a power source enters the wall box via an opening therein, wherein the electrical wiring is accessible from the front of the wall box.

To complete the installation of the electrical fitting, wires from the fitting are secured to corresponding wires in the wall box, such as, via wire nuts, and the fitting is secured, typically via screws that engage tubular openings (threaded or unthreaded - for self-tapping screws) in the wall box. Subsequently, a decorative cover plate is installed over the fitting, by securing the cover plate, such as, via screws that engage threaded openings in the 15 fitting.

Whenever a building is undergoing renovation, the existing wall fittings and their cover plates are often in need of replacement or may simply need to be replaced to provide a different appearance. Further, it is often necessary 20 to replace a single, defective fitting.

In order to replace such existing fittings, once the old cover plates and fittings are removed, typically a new fitting is installed by securing the wires of the new fitting to their corresponding wires in the wall box (step one), securing

WO 2013/165885

PCT/US2013/038619 the fitting to the wall box (step two), and, subsequently, securing a new cover plate over the replaced fitting (step three). All of these steps are labor intensive, resulting in higher costs than would otherwise be incurred through a simpler apparatus and method of installation. Moreover, stock keeping units must be maintained for both the fittings and the cover plates, thereby increasing record-keeping costs for inventory.

When installing an electrical fitting to a wall box, the fitting has openings for fasteners to engage the wall box receiving apertures. Once the fitting is installed, the cover plate is secured via fasteners through different openings, thus requiring both different locations for the openings that receive the fasteners, but more importantly, a larger number of openings that should be required.

Therefore, it is readily apparent that there is a need for an electrical fitting and cover plate combination that reduces the typical three step installation to a wired wall box from three steps to two.

BRIEF SUMMARY OF THE INVENTION

Briefly described, in a preferred embodiment, the present invention overcomes the above-mentioned disadvantages and meets the recognized need for such a device by providing an electrical fitting, such as, for exemplary purposes only and without limitation, an electrical outlet or an electrical switch, wherein the electrical fitting comprises an integral cover

PCT/US2013/038619 plate, and wherein the composite electrical fitting/cover plate is secured via screws through the cover plate into the wall box, thereby reducing inventory for parts suppliers and labor costs for installation.

According to its major aspects and broadly stated, the present invention in its preferred form is a composite electrical fitting comprising an electrical component having an integrally-formed cover plate, the electrical component and cover plate comprising a single unit. The composite electrical fitting is dimensioned to be received by a wall box, the wall box having apertures dimensioned to cooperatively engage fasteners. The cover plate has one or more openings therein that are dimensioned to receive fasteners. Preferably, the composite electrical fitting is removably secured to the wall box via the fasteners.

The electrical component has integral wires, each having a first end and a second end, with the first end in electrical communication with the electrical component, and each wire of the electrical component has a quickconnect member disposed at the second end thereof. The quick-connect member comprises a gripping member dimensioned to secure an electrical conductor therewithin. The electrical conductor typically comprises a sheath therearound, and the quick-connect member has a cutting member dimensioned to pierce the sheath.

WO 2013/165885 PCT/US2013/038619

The electrical component may comprise an electrical outlet having one or more receptacles for receiving electrical plugs, and/or may comprise an electrical switch. Preferably, the electrical component comprises two receptacles. Alternatively, the electrical component comprises four 5 receptacles.

In the course of either an initial installation or for remodelling, an electrical fitting/cover plate combination is obtained and each of its wires is secured to a corresponding wire coming out of the electrical wall box via the 10 quick-connect member which pierces the insulating sheath of the wire coming from the wall box. Subsequently, the electrical fitting/cover plate combination is secured to the electrical wall box by passing one or more fasteners through the openings in the cover plate and engaging the fasteners cooperatively with receiving apertures in the wall box.

More specifically, the present invention is a composite electrical fitting having an electrical component and a cover plate that are integrally formed together. The electrical component comprises for exemplary purposes only, an outlet or a switch which is installed in a wall section.

Typically, the wall section has an opening cut therein to allow access to electrical wall boxes from outside of the wall. The wall box is typically secured to a selected stud within the wall via a nail or a screw. The wall box has apertures for receiving screws to retain an electrical component therein and

CA 02877293 2014-12-18

WO 2013/165885

PCT/US2013/038619 has an opening in the rear, sides or top of wall box to permit power supply wiring comprising a group of insulated conductors to pass into the wall box. The insulated conductors comprise conductors with insulating sheaths surrounding the conductors to insulate them.

The cover plate of the composite electrical fitting comprises throughholes dimensioned to receive fasteners inserted therethrough. The electrical component comprises, preferably, a duplex outlet having wires extending therefrom, such as, for exemplary purposes only, a hot wire, a neutral wire and a ground wire. The hot wire, the neutral wire and the ground wire each have a first end and a second end. The duplex outlet further comprises an upper receptacle and a lower receptacle, both dimensioned to receive electrical plugs for lamps, appliances or similar. The upper receptacle and lower receptacle are connected in parallel so that a single set of wires exits the duplex outlet.

At that end of the wires from the electrical component, there are quickconnectors that have gripping members to secure a wire therein and/or cutting members to pierce the insulation sheath of the insulated conductors disposed therein to provide electrical communication between the conductor and the electrical component. In an alternative embodiment, the composite electrical fitting may not have quick-connectors, but, instead, is connected to power supply wires coming from the wall box via wirenuts.
