Abstract
An electrical junction box for supporting a hanging load includes a base plate and a sidewall extending from it. The base plate has a pair of square bolts holes at opposite positions next to the sidewall. The sidewall has a pair of tabs bent inward, each tab having a bolt hole aligned with one of the square bolt holes. A square necked carriage bolt extends through each square bolt hole and its aligned tab bolt hole, with a lock nut on each of the bolts for supporting the hanging load. A spacer sleeve surrounds each of the bolts, between the base plate and the tabs, forming a rigid structure when the nuts are tightened. The sidewall further includes mounting holes for side mounting of the junction box for a supporting structure, permitting flush mounting of the box relative to a ceiling.
Claims10
An electrical junction box for supporting a hanging load, said junction box including a base plate and a peripheral sidewall extending therefrom, said base and sidewall together forming a junction box cavity;
- said base plate defining a spaced plurality of base plate bolt holes adjacent said sidewall;
- said sidewall including a spaced plurality of inwardly extending tabs each defining a tab bolt hole in alignment with one of said base plate bolt holes;
- said sidewall further defining a plurality of mounting holes for side mounting of said junction box for a supporting structure;
- and
- a bolt extending through each of said base plate bolt holes and the tab bolt hole aligned therewith, and a lock nut engaged with each of said bolts for supporting said hanging load on said box.
An electrical junction box assembly for supporting from the underside thereof a bracket for a hanging load, said assembly including a junction box having a base plate and a peripheral sidewall extending downwardly therefrom, said base plate and sidewall together forming a junction box cavity open at its lower end and closed at its upper end by said base plate,
- said base plate defining a pair of base plate bolt holes at substantially opposite positions on said base plate and adjacent said sidewall;
- said sidewall including a pair of integral tabs extending transversely inwardly of said cavity adjacent the lower end thereof, and each defining a tab bolt hole in alignment with one of said base plate bolt holes;
- said sidewall further defining a plurality of mounting holes for side mounting of said junction box to a supporting structure;
- a bolt having a shank portion extending downwardly and slidably through each of said base plate bolt holes and the tab bolt hole aligned therewith, and having a head portion engaged with the upper surface of said base plate,
- a nut threadably engaged with the lower end of each of said bolts for supporting said bracket from the underside of said box, and
- a spacer sleeve surrounding each of said bolts between said base plate and said tabs, respectively.
An electrical junction box assembly for supporting from the underside thereof a bracket for a hanging load, said assembly including a junction box having a base plate and a peripheral sidewall extending downwardly therefrom, said base plate and sidewall together forming a junction box cavity open at its lower end, and closed at its upper end by said base plate,
- said base plate defining a pair of base palte bolt holes at substantially opposite positions on said base plate and adjacent said sidewall,
- a pair of bolts each having a shank portion extending downwardly and slidably adjacent its upper end through one of said base plate bolt holes, and slidably adjacent its lower end through a registering opening in said bracket,
- a nut threadably engaged with the lower end of each of said bolts beneath said bracket for supporting said bracket from the underside of said box, and
- a spacer sleeve surrounding each of said bolts between said base plate and said bracket.
