1 Claim. 1
The invention relates to improvements in electric light fixtures and the like as described in the present specification and illustrated in the accompanying drawings that form a part of the same.
The invention consists essentially of the novel features of construction as pointed out broadly and specifically in the claim for novelty following a description containing an explanation in detail of an acceptable form of the invention.
The objects of the invention are, to provide a display fixture in which the fluorescent light tube may be easily removed for cleaning or replacement; to devise a display fixture for fluorescent lamps which may be easily opened and closed to provide access to the interior of same; to furnish an electric light fixture simple in construction and inexpensive to manufacture; to provide a light fixture attractive in appearance and adapted to diffuse the light from therein effectively; to furnish a light fixture which may be used in stores, showrooms, offices and the like; and generally to provide an electric light fixture which will be durable and efiicient for its purpose.
In the drawings:
Figure l is a perspective View showing the light fixture ready for use.
Figure 2 is a perspective view showing the light fixture partly open.
Figure 3 is an end view of the fixture with one end removed therefrom.
Figure 4 is a sectional view as taken on the line 4-4 in Figure 3.
Figure 5 is a detail perspective view showing one of the end brackets for the translucent panels.
Figure 6 is a sectional view as taken on the line 6-6 in Figure 5.
Figure '7 is a side elevation of the fixture.
Figure 8 is an end view of the fixture.
Figure 9 is a vertical sectional view of the fixture as taken on the line 9-9 in Figure 8.
Figure 10 is a vertical sectional view of the fixture illustrating the reflectors in their telescopic position.
Figure 11 is a vertical sectional view as taken on the line I I-l I in Figure '7.
Like numerals of reference indicate corresponding parts in the various figures.
Referring to the drawings, the electric light fixture consists of the body or support member as indicated by the numeral In. This body I0 is adapted to be supported by any suitable means and has the end members H and I2 fixedly secured thereto. The body H] is adapted to mount 2 the fluorescent light tubes and other equipment in a conventional manner.
The brackets l3 and [4 are pivotally secured tothe end members H and I2, respectively. These brackets are formed in the shape of a channel and each are closed at one end thereof. The ends of the translucent panels !5 are accommodated in the channel formation of the brackets 3 and it. The closed end of each of the brackets is towards the lower apex of the fixture, thus holding the panels i5 substantially in position in the channel formation of same. The upper ends of the brackets l3 and I 4 are open, thus facilitating removal or replacement of the panels l5.
The brackets l3 and H! which are pivotally secured to the end members I l and i2 are adapted to be detachably secured in a closed position by means of the boss it on each end of these brackets engaging in the recesses ll in the end members. When it is desired to clean or replace the fluorescent light tubes, the translucent panels may be easily hinged outward from the lower apex of the fixture.
The longitudinal member 18 is fixedly secured to the lower apex of the end members H and i2, thus holding same substantially in position.
The body IE3 has its longitudinal side walls l9 and 2G terminating in flanges 2! and 22 which are adapted to be engaged by the flanges 23 and 2 of the slidable reflector 25 which is suitably shaped and is in telescopic engagement with the slidable reflector 26, the latter also havingthe flanges 2'! and 28 which overlap the flanges 23 and 2% of the reflector 25. The outer ends of the refiectors 25 and 28 may be detachably secured to the brackets 29 and 30 by means of the fastening members 3| and 32, these "brackets being in turn, secured to the end plates ii and 52.
In this way, it will be seen from the foregoing that the interior of the fluorescent light fixture is easily accessible for repairs or replacement of lamps simply by tilting the panels 55 so as to replace the lamps and when it is desired to repair the sockets or other parts of the fixture, the refiectors may be contracted or expanded as the case may be, so as to expose that port-ion of the interior body that may need attention.
What I claim is:
In an electric light fixture, a body adapted to mount an electric lamp, and having longitudinal side wal's terminating in flanges, end members fixedly secured to said body, brackets fixedly secured to said end members, reflectors telescopically engaging with one another and over.
lapping the flanges of said body and detachably Number secured to said end members. 2,268,713 NORMAN NEUMAN. 2,284,534 2,314,103 REFERENCES CITED 5 2,330,507 The following references are of record in the 2,335,736 file of this patent: 2,382,878
