CEILING FIXTURES Y Filed Feb. 26, 1958 United States Patent C) CEILING FIXTURES Isidore Wolar, 290 Collins Ave., `Mount Vernon, N.Y. Filed Feb. 26, 1958, Ser. No. 717,777

3 Claims. (Cl. 248-343) This invention relates in general to a ceiling fixture hanger and more particularly to a novel and improved fixture hanger for attachment to a ceiling mount and universally adjustable in a horizontal plane with respect to said mount.

One object of the invention resides in the provision of a fixture hanger for attachment to a ceiling mount and adjustable with respect thereto for accurate positioning and alignment of the fixture carried by the hanger.

Another object of the invention resides in the provision of a ceiling hanger characterized by its simplicity, ruggedness, low cost and ease of attachment to a ceiling support. By reason of a novel and improved arrangement and cooperation of elements wide latitude in positioning of the hanger relative to the mount is afforded and the hanger once secured to the ceiling will remain in the adjusted position.

Other objects and advantages will become apparent to those skilled in the art as the following description proceeds.

In the drawings:

Figure 1 shows a cross sectional view of the invention in position on a ceiling for the support of a fixture;

Figure 2 is a bottom view of the support and hanger of Figure 1;

Figure 3 is another bottom plan view of the support and hanger of Figure l and illustrates the cooperation of the hanger with the support;

Figure 4 is a perspective view of the fixture hanger according to the invention.

The novel and improved ceiling fixture hanger in accordance with the invention is adapted ot be secured to a ceiling support and cooperates with the ceiling support and the ceiling itself to afford a secure, dependable and rugged fixture hanger. Moreover, by reason of an improved combination and arrangement of elements wide latitude in the adjustment in the hanger relative to the support is obtainable so that should two or more hangers be used for the support of an individual fixture they can be readily aligned one with the other to facilitate proper alignment of the fixture with the ceiling or room.

This improved hanger is generally denoted by the numeral and is carried by a ceiling member denoted by the numeral 11, the latter being embedded in a ceiling 12 of concrete or other suitable material.

More specifically, the ceiling member 11 is preferably formed of sheet metal and includes a lower box-like portion 13 formed by side walls 14 and 15, a top Wall 16 and an end wall 17, of which only one is shown in Figure 1. The bottom wall 18 of the ceiling support is slotted, as indicated at 18 and the lower face of this wall is preferably even with the ceiling surface. In this particular embodiment of the support, the side walls 14 and 15 extend upwardly and are connected by a transverse member 19. With this arrangement the divergent walls 15 and 16 tend to hold the support in the ceiling material, and the material when poured flows about the upper end of the side walls and about the transverse member 19 to secure thek support more `firmly*inTpaCe.V

The fixture hanger 10 is in the form of a at platev having a downwardly depending hook 20 and anelon-4 gated slot 21 generally parallel with the hook 20. The" hook is formed integrally with the 'plate 1'0 andv is formed'by cutting spaced parallel slots 22 and' 23 inthe plate extending from the plate edge 24 in a direction perpendicular to the long axis of the slot 21. The outer edge of the hook is rounded as indicated at 245, and a diagonalslot 26 is formed therein for the attachment of a fixture to be supported; A hole 27 extends'thr'ough the outer end of the hook 20 'to kreceive a' pin or"v other suitable means to prevent accidental detachment of the fixture from the hook.

The plate 10 is secured to the ceiling support by a bolt 28 or other suitable fastening means extending through the slot 21 of the plate 10, the slot 18' of the support 11 and engaging a nut like member 29 slidably retained within the chamber 13 of the support 11. The slot 18 having an elongated configuration as viewed in Figure 2 coupled with the utilization of the slot 21 in the face 10 also of an elongated configuration, affords a relatively wide range of adjustment of the plate 10 relative to the hanger.

Figure 2 illustrates this adjustable feature and shows that the plate can be moved a distance equal to the sum of the length of the

slots

18 and 21 when the long axes ofthe slots are aligned. When the slots are out of alignment the lateral adjustment of the plate 10 is determined by the length of the slot 21 alone.

yFigure 3 of the drawings illustrates still another feature of the invention, namely, the angular adjustment of the plate 10 relative to the support 11. It will be observed from this figure that the plate not only can be positioned at any angle relative to the support, but also can be displaced relative to the :support without modifying the angular position.

In order to secure the plate to the ceiling and prevent displacement by reason of vibration or stresses applied by the fixture supported thereby, means are provided for forcibly engaging the ceiling when the plate 10 is in position as shown, for instance, in Figure l. In the illustrated embodiment of the invention, and particularly as shown in Figure 4, the corners-of the plate adjoining the edge 24 are bent upwardly as indicated at 30 to provide pointed portions which are forced into the ceiling when the screw 28 is tightened. While these projections are shown in only two corners of the plate 10, they may, if desired, be included on all four corners. Under certain conditions it may be desirable to use a modified structure for engaging the ceiling by bending a portion of the plate upwardly so that one or more edges of the plate will bear firmly against the ceiling when the plate is in place. This is illustrated in the drawings wherein a portion 10' of the plate 10 is bent upwardly along the line 31 generally parallel to the long axis of the slot 21.

While only certain embodiments of the invention have been described, it is apparent that modifications and changes may be made without departing from the true scope and spirit thereof. For instance, the slot 21 of the plate may be placed at any desired angle relative to the hook 20. The plate may be provided with both projections 30 as well as deflected portions 10 and such deflected portions may be placed in any desired angular relationship with reference to the hook 20 in the slot 21. The plate may be of any desired shape and other types of supports may be used for attaching the plate to the ceiling.

What is claimed is:

l. A ceiling fixture comprising a generally rectangular plate, said plate having an elongated slot extending therethrough and disposed centrally thereof, said slot being adapted to receive fastening means to adjustably secure said plate to a supporting surface, means on said plate extending in the direction of said supporting surface to frictionally engage said supporting surface to hold the plate in an adjusted position, the last said means producing a stress on said fastening means to effect rm frictional engagement between said fastening means and said plate, and a hook member carried by said plate in closely spaced relationship to said slot, said hook member extending from said plate in a direction opposite to the rst said means for receiving and supporting a pendant xture support.

i 2. A ceiling fixture hanger according to claim 1 wherein said hook member is spaced inwardly from one edge of said plate a distance substantially equal to the height 15 2,767,952
