Adjustable electrical outlet box assembly
The present invention is directed to an adjustable electrical outlet box assembly comprising an outlet box, an electrical outlet assembly, and an adaptor. The adaptor is located between the box and the outlet assembly and is positioned at least partially within the box. The adaptor includes opposing mounting flanges and opposing outlet assembly support tabs that are displaced from the mounting flanges. The adaptor may be adjusted to different heights, relative to the outlet box, to accommodate different thicknesses for different floor or wall covering materials. Due to the offset between the adaptor mounting flanges and the outlet support tabs, the outer surfaces of the outlet assembly will lie generally in the same plane as, or slightly recessed from the plane of the mounting flanges. The resulting outlet box installation can be used with a flush mounted covet plate which protects and secures the electrical outlet assembly.

The present invention relates generally to hardware for mounting electrical outlet boxes. More particularly, the invention relates to an electrical outlet box assembly including an adaptor to permit optimum placement of the electrical outlet with a variety of different floor and/or wall materials covering the box.
Various electrical outlet box assemblies having adjustability features are known in the art. Examples of prior art devices of this type as disclosed in U.S. Pat. Nos. 3,878,315; 4,747,506; 5,012,043; 5,253,831; and 5,289,934.
Despite these prior art devices, a need nonetheless exists for a simple, low cost and versatile electrical outlet box assembly that can accommodate a wide range of floor and wall covering materials. A need also exists for such an assembly that will function effectively with flush mounting cover plates that are now widely used in residential and commercial construction.
SUMMARY OF THE INVENTIONThe present invention is directed to an adjustable electrical outlet box assembly comprising an outlet box, an electrical outlet assembly, and an adaptor. The adaptor is located between the box and the outlet assembly and is positioned at least partially within the box. The adaptor includes opposing mounting flanges and opposing outlet assembly support tabs that are displaced from the mounting flanges. The adaptor may be adjusted to different heights, relative to the outlet box, to accommodate different thicknesses for different floor or wall covering materials. Due to the offset between the adaptor mounting flanges and the outlet support tabs, the outer surfaces of the outlet assembly will lie generally in the same plane as, or slightly recessed from the plane of the mounting flanges. The resulting outlet box installation can be used with a flush mounted cover plate which protects and secures the electrical outlet assembly.
BRIEF DESCRIPTION OF THE DRAWINGSThe novel features which are characteristic of the present invention are set forth in the appended claims. However, the invention's preferred embodiments, together with further objects and attendant advantages, will be best understood by reference to the following detailed description taken in connection with the accompanying drawings in which:
With reference to
In accordance with a preferred embodiment of the present invention, the adaptor 14 is assembled between the outlet box 10 and outlet assembly 12. The adaptor 14 is illustrated in greater detail in
The adaptor 14 may be fabricated from sheet metal or any number of different plastic materials all well known to those of skill in the art. It is sized to have a slide fit within housing 16 of outlet box 10. The adaptor allows the outlet assembly 12 to be positioned precisely so that the outer surfaces of the outlets 24 are located in generally the same plane as the outer surface 50 of the floorboards 52 (or any other covering panel or structure employed with the particular installation). Alternatively, the adaptor may be configured to position the outer surfaces of the outlets 24 so as to be recessed from the outer surface of the covering member.
Use of the adaptor 14 as just described facilitates the use of a flush mounted cover plate 60 to protect the receptacle assembly 12 and reduce the likelihood of unintended contact with the power and/or data transmission lines. To this end, the cover plate 60 has threaded apertures 62 that receive threaded inserts 64 to completely cover and close off the outlets 24. In addition, a cover gasket 66 and outlet assembly gasket 68 may be employed to reduce the ingress of moisture or other contaminants into the outlet box assembly.
It will be appreciated by those skilled in the art, that covering materials (flooring, wallboard, etc.) with widely varying thickness may be used with the preferred embodiment of the present invention. The minimum thickness of suitable covering materials will be defined by the degree of offset between adaptor flanges 36 and adaptor tabs 38, while the maximum thickness of suitable covering materials will be defined by the depth of insert 30.
It will be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered by the appended claims.
Claims

- an outlet box;
- an outlet assembly;
- an insert having a size and configuration to be positioned outside the outlet assembly and having a plurality of sidewalls insertable within the outlet box and an extremity extending outwardly from the outlet box and around one or more outlets of the outlet assembly;
- a cover plate positionable on an outer surface of the installation structure; and
- one or more gaskets located between the cover and the insert to reduce the ingress of moisture or other contaminants into the outlet box assembly.
8. The electrical outlet box assembly of claim 7 wherein the outlet box is mounted to the installation structure by one or more mounting flanges.
9. The electrical outlet box assembly of claim 8 wherein said mounting flanges are an integral part of said insert.
