MOUNTINGPLATE FOR FIXTURES EMPLOYING ELONGATED TUBULAR LAMPS Filed July 1, 1950 INVENTOR ROBERT 6. MARCH! 0 24 25 /a 3 B C ATTORNEY Patented July 14, 1953 MOUNTING PLATE FORFIXTURES'EMPLOY- ING ELONGATED TUBULAR LAMPS Robert G. Marchisio, Wenham, Mass., assignor to Sylvania Electric Products Inc., Salem, Mass. a corporation of Massachusetts Application July 1, 1950, Serial No. 171,592
1 Claim. 1
This inventionrelates to electric lighting fixtures and more particularly to fixtures employing elongated tubular light sources, such as fluorescent lamps.
To the'lighting fixture manufacturer, the introduction of each new lamp size presents .addi tional fixture manufacturing problems,,one of the more important of which is the stocking of a complete set of fixture components to accommodate the new size lamp. The stocking of different sizes of fixture components for differ ent sizes of lamps not only materially increases the minimum necessary operating inventory but,
. in the case of some of the longer lamps, such as the 96 inch long, 75 watt fluorescent lamp, for example, assembly operationsare quite awkward in a bench-type assembly line system be- I cause ofthe extreme length of the units.
It is, therefore, an object of our invention to provide a device which will permit the use of basic fixture units in fixtures employin lamps of various sizes. V
Another object of our invention is to provide a device which will permit the use of basic retrated with reference to a specific type of fluorescent lighting fixture. Other modifications of the device of our invention and their adaptability to fixtures other than the specific one shown and described will be readily apparent to those skilled in the art.
Further objects, advantages and features will be apparent from the following description when read in conjunction with the accompanying drawing in which:
Figure 1 is a plan view of a fluorescent lighting fixture with which the device .of our invention may be employed.
Figure 2 is a transverse sectional View of the fluorescent lighting fixture of Figure 1, taken along the line 2- 2 thereof, and showing a specific embodiment of our invention.
. mounted on the fixture.
Figure 3 is a fragmentary top perspective view v 2 V ture l comprises an elongated channel chassis 2 with end plates 3 and 4 attached to the ends thereof, a mounting plate assembly 5 attached to and depending from the chassis 2 transverse thereof and midway between its ends, a pair of reflectors 6 and l and a plurality of lightcontrolling panels 8, 9, l0 and II. Fluorescentof louvers 14 extending transversely thereof and attached thereto.
In the specific modification shown in the drawing, the mounting plate assembly 5 comprises a pair of plates l5, eachof which has a 1ouver I6 formed integral therewith, attached to one another, a reflector-supporting member I! attached to the opposite faces of each of the two plates l5, and a latch 18 pivotally mounted between th offset ends of the louvers l6-at each end thereof. Each of the plates l5 of the mounting plate assembly 5 has a pair of ears I9 formed integral therewith through which the mounting plate assembly 5 is attached to the chassis 2.
As mentioned above, the mounting plate assembly of our invention permits the use of multiple reflector and panels units in assembling fluorescent lighting fixtures. In assembling the instant fixture shown in the drawing; the end plates 3 and 4, with the lamp holders [3 mounted thereon, are attached to the ends of the chassis 2. The mounting plate assembly 5 is then attached to the chassis 2 midway between the ends thereof by securing the ears I9 of the mounting plate assembly 5 to the chassis.
The reflector 6 is then placed in position. One end of the reflector is attached to the end plate 3, by any suitable means. The other end of the reflector has a pair of slots 20 cut therein, through which the reflector supporting member H, which comprises a pair of resilient metal fingers 2i, extends. As this end of the .reflector is swung into position, the fingers 2| of the reflector supporting member I! are depressed to per-- tance sufficient to bring the slots 20 therein in line with the fingers 2|. The fingers 2| are then released and snap into the slots 20, thereby securely retaining and supporting this end of the reflector.
The light-controlling panels 8 and 9 are then One end of each of the panels 8 and 9 is attached to or mounted on the end plate 3 in some suitable manner. The
other end of each'of the panels 8 and 9 is hung 3 e on the hook portion 22 of a bracket 23 mounted on the chassis 2 above and in register with the mounting plate assembly 5.
The reflector I and the light-controlling panels I!) and 'II are mounted in the same manner as the reflector 6 and the light-controlling panels 8 and 9 respectively. The latches l8, each of which has aresilien-t clip 24 attached to the free end thereof, are then swung upwardly into engagement with the adjacent ends of panels-8 and I and 9 and II respectively. Each of the game clips 24 has an offset portionj2'5 lw'hich locks the panels 8, 9, l0 and II in the hook portion 'means on opposite ifaces ,o'f said mounting plate for supportingftheradjacentxends of each of said reflectors; a transverse louver on said amounting 4 plate and disposed between the adjacent ends of each of said reflectors; at least two lightcontrolling panels disposed end-to-end, parallel to said chassis along each side thereof and spaced therefrom with the ends of said panels disposed adjacent to said end plates mounted thereonj a bracket mounted on each'side of said chassis above and in register with the transverse louver on said mounting plate, the free end of each of said brackets having a book portion on which the adjacentzends of each of said panels are'jsu'pported; and 'a latch pivotally mounted on each end of said transverse louver on said mounting plate and disposed between the adjacent ends of said panels the free end of said latch" overlying and frictionally engaging the adjacent ends of said panels at the points at which said panels are supported on said bracket.
