Abstract

An electrical outlet box mounting bracket assembly including a box of generally rectangular parallelepiped configuration, a pair of spaced channel elements on a side of the box, and an L-shaped bracket including a flange having side edges extending into the channels to engage the bracket with the box. The bracket further includes a pair of flexible tongues adjacent the side edges of the flange, which tongues engage tabs at the ends of the channels.

Claims

1. An electrical outlet box and mounting bracket assembly comprising:

a synthetic resin box forming an open-sided enclosure having at least one side wall;

a pair of spaced channel elements on said side wall, each of said channel elements defining a respective channel space and including;

a retention plate extending substantially parallel to said side wall;

a spacer plate projecting between and interconnecting the retention plate and the side wall; and

an engaging tab projecting normal to said retention plate and to said spacer plate at one end of the respective channel space, the distance separating the engaging tabs being less than the distance separating the spacer plates; and

an L-shaped bracket including;

an engaging flange having a first edge and having side edges extending into the channel elements at a location between the box and the respective retention plates of the channel elements into which the respective side edges extend;

a mounting flange extending normal to the plane of the engaging flange and having one edge thereof connected to said first edge of said engaging flange; and

flexible, resilient tongue means connected to said engaging flange adjacent its first edge connected to said mounting flange and engaging said engaging tabs to prevent movement of said bracket in a direction normal to the plane of said mounting flange, said tongue means including undercuts receiving said engaging tabs.

2. An electrical outlet box and mounting bracket assembly as defined in claim 1 wherein said box is of right parallelepiped configuration.

3. An electrical outlet box and mounting bracket assembly as defined in claim 1 wherein said tongue means comprises a pair of flexible tongues located adjacent the opposite sides of said engaging flange, and each having an undercut therein and each positioned at one end of one of said side edges adjacent said mounting flange at a position to pass over and snap interlock with an adjacent one of said engaging tabs as said one tab snaps into the undercut in the respective interlocked tongue.

4. An electrical outlet box and mounting bracket assembly as defined in claim 3 wherein said tongues are spaced from each other by a distance less than the distance which separates said side edges.

5. An electrical outlet box and mounting bracket assembly as defined in claim 4 wherein each of said tongues includes a beveled edge, and the beveled edges of said tongues are spaced from each other substantially the same distance as said engaging tabs are spaced from each other.

6. An electrical outlet box and mounting bracket assembly as defined in claim 1 wherein said mounting flange has a plurality of fastener holes therethrough and further includes:

a pair of outwardly extending side plates on opposite sides of the mounting flange, and each defining a recess extending inwardly therein toward the other of the side plates; and

a pair of substantially parallel, spaced tabs projecting normal to the plane of each of the side plates with each of said pairs of tabs including tabs positioned on opposite sides of the respective side plate-defined recess.

7. An electrical outlet box and mounting bracket assembly as defined in claim 6 wherein said box is a right parallelepiped.

8. An electrical outlet box and mounting bracket assembly as defined in claim 6 wherein said tongue means includes two spaced, flexible resilient tongues each having a pair of notches formed therein and receiving one of said engaging tabs in one of said notches.
