Abstract

An adjustable floor box assembly including: 1) an electrical box having a front edge, a sidewall and opposing vertical edges, electrical box vertical channels at the opposing sidewall vertical edges; a bolt guide on the sidewall adjacent the front edge in vertical alignment with a slot in the sidewall; and 2) an adjustable flange including: a) a horizontal member including, an aperture for the insertion of a threaded adjustment bolt; and b) an integral vertical member having vertical flange edges and flange channels on the vertical flange edges that slidably engage the vertical channels, and at least one adjustment bolt engagement member that engages the threads of an threaded adjustment bolt inserted through the bolt guide, so that, as the adjustment bolt is rotated, the adjustable flange moves slidably up and down as the vertical flange edges and flange channels move slidably in the electrical box vertical channels.

Claims

1. An adjustable floor box comprising:

an electrical box including a front edge and a first sidewall having first channels and a bolt receiver;

an adjustable flange engaged in said first channels of said first sidewall, said adjustable flange slideable with respect to said first sidewall, said adjustable flange including edges and second channels;

said adjustable flange including a flange member substantially planar with respect to said front edge of said electrical box and a bolt engagement portion, said flange member including a notch therein;

an adjustment bolt extending between said flange member and said bolt receiver, said adjustment bolt including threads and a head;

said bolt engagement portion of said adjustable flange engaging the threads of said adjustment bolt thereby enabling adjustable flange to slide up and down with respect to said electrical box as said edges and said second channels of said adjustable flange move slidably in said first channels of said electrical box thereby altering the vertical location of said flange member relative to the location of said electrical box and providing accurate adjustment of said adjustable floor box assembly with respect to a floor surface;

said notch in said adjustable flange enabling access to the head of said adjustment bolt;

a cover plate secured to said front edge of said electrical box, said cover plate including outlet covers and an access hole; and

said access hole of said cover plate axially aligned with said adjustment bolt enabling rotation of said adjustment bolt to adjust the depth of said adjustable floor box within a floor.
