Abstract

At least one sidewall of the electrical outlet box is formed with boss members defining slots for receiving and retaining the attaching portion of a generally L-shaped mounting bracket which also includes a mounting portion adapted to be secured to a suitable support structure. As preferably embodied, the outlet box is made of a moldable plastic material and includes wedge-like restraining means on the sidewall for ratcheting into an aperture formed in the attaching portion of the bracket when the bracket is fully seated in the slots in order to prevent removal of the bracket from the outlet box.

Claims

1. An electrical outlet box mounting assembly which includes:

at least one generally flat sidewall portion on an electrical outlet box having a generally open front face;

a mounting bracket having an essentially flat attaching portion and a mounting portion adapted to be secured to a suitable support structure for mounting the box thereto;

slot means formed on said sidewall portion, said slot means adapted for slidably receiving and retaining said flat attaching portion of said bracket when inserted thereinto;

first stop means formed on said sidewall portion for preventing insertion of said attaching portion beyond a predetermined point;

restraining means formed on said sidewall portion, said restraining means providing a detent surface; and

receiving means formed in said attaching portion, said receiving means proportioned to generally surround said restraining means when said attaching portion is essentially fully seated in said slot means with said detent surface generally abutting an edge of said receiving means, said restraining means and said receiving means being proportioned to permit insertion of said attaching portion into said slot means yet substantially prevent withdrawal of said attaching portion from said slot means once said attaching portion is essentially fully seated in said slot means, such that said mounting bracket is lockably engageable in said slot means without threaded fasteners whereby the electrical outlet box can be mounted to the support structure by securing said mounting portion thereto.

2. An electrical outlet box mounting assembly according to claim 1 which further includes second stop means formed on a second sidewall portion, said second stop means recessed from said front of said outlet box a distance essentially equal to the thickness of the wall supported by said support member.

3. An electrical outlet box mounting assembly according to claim 1 wherein said slot means are provided by boss means formed on said sidewall portion, said boss means defining a pair of slots with said sidewall portion for slidably receiving said attaching portion of said bracket, and providing said first stop means for restricting slidable insertion of said attaching portion into said slots beyond a predetermined position.

4. An electrical outlet box mounting assembly according to claim 3 wherein said mounting bracket comprises a generally L-shaped member having an essentially flat first leg adapted for insertion into said slots defined by said boss means and a second leg adapted to be secured to the support structure.

5. An electrical outlet box mounting assembly according to claim 4 wherein said restraining means comprises detent means formed on said sidewall portion and said receiving means comprises an aperture formed in said first leg for lockably engaging said detent means, such that said detent means permits insertion of said first leg into said slots defined by said boss members, yet substantially prevents removal of said first leg from said slots after said first leg is fully seated in said slots, to provide a generally permanent coupling between said outlet box and said mounting bracket.

6. An electrical outlet box mounting assembly according to claim 5 wherein the electrical outlet box is made from a moldable plastic material.

7. An electrical outlet box mounting assembly according to claim 6 wherein said detent means comprises a generally wedge-like member formed on said sidewall portion, said wedge-like member being inclined in the direction of insertion of said first leg and forming said detent surface generally perpendicular to said sidewall portion at its rearward edge, and wherein said first leg is formed with an aperture positioned and dimensioned to surround said wedge-like member when said first leg is fully seated in said slots, such that during insertion of said first leg into said slots, said sidewall portion resiliently yields inwardly as said first leg rides over said wedge-like member until said wedge-like member snaps into said aperture when said first leg is essentially fully seated in said slots, with said detent surface generally abutting an edge of said aperture to substantially prevent removal of said first leg from said slots.

8. An electrical outlet box mounting assembly according to claim 7 wherein the edge of the free end of said first leg is provided with a lip inclined at generally the same angle as said wedge-like member and positioned for alignment therewith during insertion to facilitate sliding of said edge over said wedge-like member.

9. An electrical outlet box mounting assembly according to claim 8 which further includes second stop means formed on a second sidewall, portion said second stop means recessed from said front of said outlet box a distance essentially equal to the thickness of the wall supported by said support member.

10. An electrical outlet box mounting assembly according to claim 8 wherein said first and second legs of said mounting bracket intersect such that when said first leg is lockably received in said slot means, said second leg defines a plane essentially parallel to the plane defined by the front face of the outlet box.

11. An electrical outlet box mounting assembly which includes:

at least one generally flat sidewall portion of a molded plastic electrical outlet box;

a mounting bracket having an essentially flat attaching portion and a mounting portion adapted to be secured to a suitable support structure for mounting the box thereto, said attaching portion having an aperture formed therein;

boss means formed on said sidewall portion, defining a pair of slots with said sidewall portion, said slots adapted to slidably receive said attaching portion, and said boss means providing a stop for restricting slidable insertion of said attaching portion into said slots beyond a predetermined position;

detent means formed on said sidewall portion, said detent means comprising a generally wedge-shaped member inclined in the direction of insertion of said attaching portion, a detent surface formed at its rearward edge, generally perpendicular to said sidewall portion, said aperture in said attaching portion being positioned and dimensioned to generally surround said detent means when said attaching leg is fully seated in said slots,

such that during insertion of said attaching portion into said slots, said sidewall portion generally resiliently yields inwardly as said attaching portion rides over said wedge-shaped detent means until said detent means snaps into said aperture when said attaching portion is essentially fully seated in said slots, with said detent surface generally abutting on edge of said aperture to substantially prevent removal of said attaching portion from said slots.

12. An electrical outlet box mounting assembly according to claim 11 wherein the edge of the free end of said attaching portion is provided with a lip inclined at generally the same angle as said wedge-shaped member and positioned for alignment therewith during insertion to facilitate sliding of said edge over said wedge-sahped member.

13. An electrical outlet box mounting assembly according to claim 12 which further includes stop means formed on a second sidewall portion, said stop means recessed from said front of said outlet box a distance essentially equal to the thickness of the wall supported by said support member.

14. An electrical outlet box mounting assembly according to claim 12 wherein said mounting bracket comprises a generally L-shaped member having an essentially flat first leg adapted for insertion into said slots and a second leg adapted to be secured, to the support structure.

15. An electrical outlet box mounting assembly according to claim 14 wherein said first and second legs of said mounting bracket intersect such that when said first leg is lockably received in said slot means, said second leg defines a plane essentially parallel to the plane defined by the front face of the outlet box.
