' Thisinvention relates 'to a pendant mounting for lighting fixtures and the like;

-- The invention contemplates .means which is concealed in'the ultimate position of the fixture and its canopy for the temporary pendant supportof the fixture'during the wiring thereof, such temporary support including links which arejdivergent so as to resist fixture displacement and which collapse into concealed positionswithin the canopy, the canopy and the'mount for the links for maintaining the assembly in its permanent position.

Principal objects of the invention include an arrangement whereby the'divergent links collapse when the fixtureis raisedto its final positionand include offsets for accommodating the permanent mounting pins; the'links and mounting-channel being wholly concealed within the fixture canopy in the elevated final position of the fixture.

. The threaded stud 1 and nut 8 are used to connect the mounting channel II) to the outlet box 9 in ceiling II. The mounting channel In may be supported entirely by'the stud I or it may receive its support from the screws l2 threaded into the ceiling, or both means of support may be' used as shown. 1 v

The mounting channel 10 opens downwardly as best shown in Figs. 3 and 4, its central web-13 being desirably flat against the ceiling with the l5 depending therefrom; Suitable screws l2 and the thread I and for theadmission through the channelof the electrical supply ided near'their ends The webs l4, l5 are pro withre'gistering holes at I8 and inwardly from 12 Claims. (01.24.8 .343)

theends, the'flanges have corresponding slots at The lighting fixture generically designated by reference character has a canopy portion 2| with a downwardly channeled top wall 22 in the canopy portion. It is broadly immaterial to the present invention whether the canopy comprise a separate part, but it will be noted that the invention makes a separate canopy unnecessary.

The width of the channel 23 in the top wall 22 is materially greater than the overall width of the mounting channel II). There are openings 24 in the sides of-the;fixture which register; with openings 25 inthe channel walls 23! and 232 andjar'e' at spacings longitudinally corresponding to the'spacing between the openings l8 in the supporting channel it! fastened tothe ceiling.

..by fingers 34, 35-;

Links are used'forthe temporary support of the fixture from thej supporting channel) during wiring. Each of these links may be made of wire of generally u-shaped form. .The links. are generically designated by reference character 30.

.Each hasia transverse strandof wire 3l' extending through the slots l9oi the mounting channel III. From this depend the le gs.32",.33f which are parallel at an overall spacing whichis less; than the total width of the channel 23 in the topinember22 of the fixture canopy 2!.. The legs 32, 3.3

have outwardly turned, fingers 34, 35 at their lower ends which are engaged laterallyinapertures in the side walls of the channel =23--o f top member 22 of the light fi xture.-canopy. ltgwill be observed that the outermost .ends of the respective slots l9- are'spaced well inwardly from the holes 36, 31 inthe canopy whichare engaged With the fixture depending from the mounting channel 10, as shown in Fig. '1. the links Mare rather sharply divergentin an outward direction toward the ends of the-fixture,thustendingjto hold the fixture stable.n0n+swinging; :position' for-the connection of its wires 38. 39 withthe supply Wires-16 and H. During the makingiof 'jthQ necessary connection; the, entire weight of the fixture is suspended on the links 3ll. 5

v f When the;;wiring operationiis. complete, .1 the fixture 20 is raised;;bodily; 'thus'collapsing the links and 31 and to'the channel 23 of the top wall of the canopy'an'd between the sides of .channel 23 and the flanges M, l5 of the -cfhannelshaped-mounting Hi. The collapsed position of the links is-clearlyl'shown in-Figs. 4 andw. The

collapse of: the link- 30 to-the position-indicated is permitted ,by reason of-the lengthzof slot::..l9.

The lower and outer ends of the divergent links are at a fixed Spacing in the holes 36, 31 of the canopy and consequently all of the displacement must be accommodated at the upper ends of the the mounting pins 40 are inserted through the registering holes in the manner shown in Figs,

4 and 5 to maintain the parts in assembly.

It will be observed that the mounting channel i0 is now entirely concealed within the canopy,

being received bodily to the channel 23, together with the links which provided a temporary suspension for the fixture during wiring. The

only portions of the mounting equipment which are visible are the pins 40. Thesemay be so made as to be hardly perceptible.

It will beobserved that in order-that such pins may be received through. the registering apertures of the fixture and the mounting channel, without interference with the links 30, it

is desirable that the links be bent bodily as clearly shown in Figs. 1 and 2 so that in the collapsed positions of. the links they will. pass beneath'the plane in which the pins are disposed. This would not be necessary but for the fact that in order to achieve compactness in the particular embodiment disclosed, the slots 19 of the mounting channels are located at one side of the. pin-receiving apertures 18, while the fingers connecting the links with the fixture are located beyond the apertures 18 and, in fact,

beyond the .entrance of the mounting channel as a whole. This gives in limited space the desired. outward and downward divergence of .the links ,30 when the links are in use, as shown "in Fig. 1,, and yet the angular offset of the legs 'of the linkspermits the links to collapse into the" fixture chamber n without interference fwith the mounting pins Afl when the fixture is in its elevated position.

When the fixture is to be repaired or inter- .hang e'd with another fixture, it is only necessary to withdraw the pin in order-to drop 'thefixture to the position shown in"Fig'. l, where it is again supported on the links 30 with its wiring fully accessible.

- The lower ends. of the links have adequate flexibility so'that they maybe bent inwardly to disengage their fingers 34 and 35 from the aperture" of the canopy to completely release the fixture from the mounting channel when de- "sired. The links are simple flexed inwardly again 5 when it is desired to reengage them with a'correspo'ndingly formed canopyof the same or a different lighting fixture.

Since the links are readily engaged singly-and "are-adequate for the support of the fixture at 'all times during assembly or disassembly and :wiring, and since the links remain available for.

this purpose inthe concealed positions in which ethey .are'housedwithin the canopy, it will be apparent :that the lowering'and erection of fixtures of this sort has been greatly facilitated byfthe mounting means "herein disclosed.
