Floor box

An improved floor box for use as part of an infloor electrical power distribution system in a poured concrete floor, which floor box is assembled with other electrical distribution system components, on a sub-floor prior to the pouring of the concrete floor and is, after the concrete pour, closely encased in the poured concrete floor, the floor box comprising:

• a box and a cover for fitting on and use with the box;
• the box including a bottom wall and side walls, with the bottom wall having perimeter edges and with the side walls having first end edges that are connected with the perimeter edges of the bottom wall and second end edges that are spaced from the bottom wall, with the bottom wall and side walls defining a predetermined interior volume with the second end edges of the side walls defining an opening for the interior volume, and with the opening having a particular shape;
• means adapted for connecting the ends of electric circuit to at least one of the side walls so that the electrical conduit communicates with the interior volume and the floor box is thus connected with the infloor electrical distribution system;
• means adapted for leveling the bottom wall with respect to the sub-floor, the leveling means being affixed to the box and adapted to position the box so that the bottom wall is generally horizontal at a preselected location above the subfloor and the side walls extend upwardly from the bottom away from the subfloor so as to position the opening opposite the subfloor;
• said leveling means comprising four leveling screw mounting feet, said feet being integral with the bottom and extending outwardly therefrom and each foot being formed with a strength bending boss and also formed with adjusting screw mounting threads;
• the cover having a shape that is congruent to the particular shape of the opening and sized so that it closes the opening when the cover is fitted on the box;
• means for holding the cover down and fitted on the box and for assuring that the cover will prevent concrete from entering the interior volume during the concrete pour, the hold down means constructed for snap-in engagement of the cover and the box upon application of a force urging the cover into relation with the box that closes the opening;
• and
• wherein the holddown means includes a plurality of yieldable fingers having an abutment section extending inwardly with respect to the interior volume, to overlie the plane of the sidewalls and having a lead-in section extending outwardly from an inner extent of the abutment section away from the interior volume and beyond the side wall
• whereby the cover is secured to the box by pressing the cover against the box to engage the snap-in hold down means so as to seal the box before concrete is poured to form the floor around the in-floor distribution system and the floor box.
