BY Mann Lady, parziels 43 Marcfi ATTORNEYS United States Patent 3,039,729 LIGHTING FiXTURE SUPPORT Francis E. Nagle, Sr., 409 Madison Ave., New Milford, NJ. Filed July 24, 1959, Ser. No. 829,292 1 Claim. (Cl. 248343) This invention relates in general to lighting fixtures and in particular to a new and useful adjustable lighting fixture positioning and holding bracket.

When lighting fixtures are to be installed in a wall or a ceiling, it is first necessary to build a rough frame for the lighting fixture box at the desired location. This frame may be made by fastening wooden or metal cross members to the ceiling beams after the precise position for the lighting fixture has been accurately determined and measured. The outer portion or rough-box for the lighting fixture is then secured to the frame by nails or screws and the ceiling is finished as by plastering down to the lower level of the fixture roughbox. With such construction adjustments in the location of the frame for the fixture is difficult, it being necessary to tear down and reconstruct the cross member frame portions if changes are desired. Fine fixture positioning adjustments are not possible.

In accordance with the present invention there is provided a lighting fixture positioning and holding bracket including a rectangular frame portion which is adapted to be positioned over, and secured to, an adjacent pair of the ceiling or wall beams located in the general location in which the lighting fixture is to be located. Slideable along the frame members is a lighting fixture rough box holding bracket which is shaped to the general configuration of the lighting fixture rough-box, but made slightly larger to accommodate the rough box therein. Since the holding bracket maybe slid to any location between the supporting beams the fixture may be accurately located at any desired location. Measurements from wall to wall or from one lighting fixture to the next may be made as the bracket is slid to the desired measured location. Means are provided to easily secure the rough box to the sliding holding bracket, and after it is so secured the ceiling may be finished as desired.

If desired the frame portions may be made in two pieces to permit adjustment of the frame to the spacing of the supporting beams.

Accordingly it is an object of this invention to provide an adjustable lighting fixture holding and positioning bracket.

A further object of the invention is to provide a lighting fixture holding and positioning bracket including a fixture holding bracket which is slideable in a supporting frame, the latter being adapted to be supported on adjacent beams of a wall or ceiling.

A further object of the invention is to provide an adjustable lighting fixture holding bracket which is simple in design, rugged in construction and economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claim annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and specific objects attained by its use, reference should be had to the accompanying drawings and descriptive matter in which there are illustrated and described preferred embodiments of the invention.

In the drawings:

FIG. 4 is an enlarged partial elevation on the line 44 of FIG. 1;

FIG. 5 is a view similar to FIG. 3 but indicating the frame connected to another type of ceiling or wall support beams;

FIG. 6 is a fragmentary side elevational view of another embodiment of bracket supporting frame; and

FIG. 7 is a fragmentary side elevational view of another embodiment of bracket supporting frame.

FIG. 8 is a top plan View of the adjustable bracket of the present invention for surface mounted fixtures.

Referring to the drawings in particular, the invention embodied therein includes a rectangular supporting frame generally designated 10 having a pair of channel side members 12 and 14 which are positioned between ceiling support beams 16 and 2(? which are located in the general vicinity of the desired location of the lighting fixture to be installed. The channel members 12 and 14 are joined together at each end by cross plates 22 and 24 respectively. The channel members 12 and 14 are made up to a length corresponding to the usual wall or ceiling beam orstud spacing to permit bent down end portions 2 6, 26 of each of the cross plates 22 and 24 to be stretched beyond the far side edges of the upstanding center portion 28 of T beams 16 and 20.

in accordance with the invention a lighting fixture holding bracket generally designated 30 is mounted for sliding movement along the channel members 12 and 14 for 3C: curate positioning at any desired location between the supporting beams 16 and 29. In theembodiments illustrated in FIGS. 1 to 4 the holding bracket 34 includes a cylindrical upstanding portion 32 and an annular flanged portion 34 of a diameter great enough to permit it to be supported on horizontal portions 36 and 38 of the channel members 12. and 14. The bracket 30 also includes downwardly extending tabs 39 which hold the bracket on the portions 36 and '38.

Secured to one side of the flanged portion is an L- shaped member 4t) which includes a vertical wall spaced inwardly slightly from a vertical wall 42 of the channel member 12. A bolt or thumb screw 44 is threaded into the wall 46) and is tightened against the wall 42 when the and section taken holding bracket 30 is positioned at the desired location.

The holding bracket 30 also includes three angularly spaced upstanding bosses 46, 48 and 50 having openings 52 to receive securing studs of a rough-box of a cylindrical lighting fixture.

It should be appreciated that the bracket 30 may be made with a rectangular or other shaped central opening to accommodate rectangular or other shaped lighting fixture rough-boxes.

In FIGURE 5 the channel members 12 and 1 4 are arranged to bridge specially shaped walls beams 46 and 48. In FIG. 6 there is indicated a modified securing means for a supporting grame 59 to anchor the frame to ceiling beams 52 and 54 having laterally extending top portions 56. In this embodiment the frame 50 includes a vertical lug 58 which fits on the outside of the vertical portions of the beam 54. This end of the frame 50 is also provided with a cleat 60 which is slid over the portion 56 of the beam 54. The other end of the frame 59 is provided with a bent lug 62 which is forced around the end of the portion 56 of the beam 52.

In FIGURE 7 there is illustrated a modified frame generally designated 64 which includes on each side an outer channel member 66 and an inner channel member 68 which is slidable Within the channel member 66. Each channel member 68 and 66 is provided with a laterally elongated slot 74 to permit telescoping adjustment of the frame to permit it to bridge supporting beams of various Patented June 19, 1962' for surface mounted fixtures.

r 3 spacing. When the channel members 66 and 68 are extended to the proper length they are fastened in the extended position by tightening a ring nut 72 onto a bolt 74 Which extends through the slots 70 of each channel member.

Secured to each end of the channel members 66 and 68 are cross plates (not shown) which carry tie straps 76 made of a material such as sheet metal which may be bent to conform to any contour of supporting beam such as beams 78 and 80. The straps 76 are bent around the associated beams 78 and 80 and are bent upwardly at the bottoms of the beams to secure the ends at this location. If desired nails or screws may be used to anchor the tie straps 76 in place.

.The bracket illustrated by FIG. 8 is particularly adapted As shown, the bracket frame generally designated 90 includes channel members 91 and 92 for location between ceiling beams, not shown, in the same manner as the L bracket shown in PEG. 1. The channel members 91 and 92 are connected at respective ends by cross plate members 94 and 96. In this embodiment a fixture bracket generally designated 98 is pro: vided for mounting a junction box 100 on the underside thereof. The fixture bracket 98 includes tabs 102 at each corner which extend beneath the channel members 90 and 92 to guide the bracket for reciprocation therealong. The bracket includes an upstanding lug 104 having a threaded bolt extending therethrough for securing the bracket in the desired location as in the previous embodiment. The junction box 100 may be advantageously welded to the bracket 98 and an opening 106 is provided through each for electrical cables.

The present invention thus provides a means for quickly and accurately positioning a holding bracket for mounting a lighting fixture to either a wall or a ceiling. If desired a plurality of lighting fixture holding brackets may be slideably positioned on a supporting frame to bridge a whole ceiling or wall. Thereafter the brackets may be adjusted to the desired spacing and clamped in position. Lighting fixtures are then fastened to the brackets and they will be positioned at the precise location desired.

In constructing the supporting frame for the brackets the cross plate width is determined by the width of the fixture to be used and the beam spacing whereas the length of the channel members is determined by the beam spacing in the ceiling. If desired both the cross plates and the channel members may be made telescopically adjustable.

While specific embodiments of the invention have been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
