LAMP HOLDER ASSEMBLY Filed Jan. 16, 1964 INVENTOR.
RENE GRANDJEFAW k a ,4 W;
AGENT United States Patent 3,2tlL078 LAMP HULDER ASSEMBLY Rene Grandiean, Bondy, Seine, France, assignor to North American Philips Company, Inc, New Yorlr, N.Y., a corporation of Delaware Filed .lan. 16, 1964, Ser. No. 338,123 Claims priority, application France, Jan. 21, 1963,
. 922,052 filaims. (Cl. 248361) The invention relates to a lamp holder assembly for tube type lamps, for example holders for low pressure mercury vapor discharge tubes to a mounting beam, in which the lamp holder parts extend through an aperture of the support.
For reasons of simplicity, but without any restriction, reference will be made hereinafter to a beam for low pressure mercury vapour discharge tubes. It is known to mount low pressure mercury vapour discharge tubes to a beam which has the form of a channel and the length of which is adapted to that of the tube. At the end of the beam, apertures of a suitable shape are provided in which the holders for the tubes are arranged during assembly. For easy transit of the assembly it is recommendable in general not to mount the tubes and holders on the beam in the factory but to leave this to the user or electrician. It is therefore necessary that assembly be realizable in a simple and economical manner.
Heretofore during assembly, the tube holders are usually arranged in apertures of the beam provided for this purpose. Then a holder is attached to the beam by screwing on a bolt which extends through a recess of the holder and is screwed in a hole which is provided with screw thread. If the hole in question is not screw-threaded, use is made of a bolt and a nut.
It is an object of the invention to simplify the prior assembly procedure.
The invention is not restricted to the attachment of hold ers for low pressure mercury vapour discharge tubes to a support. A beam with a lamp holder attachment according to the invention may be constructed for any number of lamp tubes. Such a beam may be constructed, for example, for a single tube or for two or more tubes. According to a particular embodiment of the invention a the brace may be constructed so that either one tube can be mounted in the centre of the beam or that two side by side parallel tubes can be mounted.
In order that the invention may readily be carried into effect, it will now be described more fully, by way of example, with reference to the accompanying drawing, in which FIG. 1 is a perspective view of one end of a mounting beam and tube holder assembly according to the invention.
FIG. 2 shows the brace of FIG. I removed.
FIG. 3 shows the supporting member.
FIG. 4 shows the brace.
The beam 1 shown in FlGS. 1 and 2 is meant for two lamp tubes. This beam consists of a flanged sheet material which is closed at both ends by an end wall 2. The end wall 2 comprises flanged edge portions 211 which are ice soldered against the inner side of the walls of the beam 1. In the proximity of this end a supporting member 3 is permanently fixed in the beam by soldering or welding. This supporting member 3 engages the tube holders d. For this purpose each supporting member is provided with recesses 3a which are shaped so that the thin portions of the tube holders 4 can pass through them (and through underlying recesses in the beam 1). In this manner the thicker portions db and 40 rest on the supporting member. Portions 4b, 4c of holder 4 are separated by a recess or channel 4a.
According to the embodiment of the invention shown, the tube holders 4 are held in place on the beam by a somewhat resilient brace 5, which is angular. The lugs 5a of this brace fit in recesses 2a which are provided in the edges 2b of the end walls 2 and walls of the beam 1 connected together. The strip-shaped brace 5 forces the tube holders 4, in the recesses of the supporting member, in a resilient manner. The brace comprises dished portions 5b and 50 which also force the tube holder against the end wall 2 of the beam. The lugs 3b on the supporting member 3 lit in the cavities 4a of these holders.
When using such a device, the assembling of the tube holders is particularly simple. The holders are pushed through the apertures 3:; (FIG. 2), and the brace is snapped in place as shown in FIG. 1.
In the embodiment shown, the depression 50 has no function. However, it is also possible to use this brace for mounting beams with either one, or two juxtaposed, tube holders.
What I claimed is:
1. Apparatus for assembling a lamp holder with a channel-shaped mounting beam comprising .a support member attached within said beam adjacent at least one end thereof, said support member having recesses for receiving said lamp holder, and a brace member having at least one dished portion engaging said lamp holder and beam for clamping said lamp holder against said support member.
2. Apparatus according to claim 1 wherein said beam is closed at said one end by an end wall member and said beam is provided with apertures corresponding with the said recesses in said support member.
3. Apparatus according to claim 1 wherein said lamp holder is provided with a recess for receiving the dished portion of said brace member.
4. Apparatus according to claim 1 wherein said support member is provided with both lugs and recess and said tube holder is provided with a channel for receiving said lug.
5. Apparatus according to claim 1 wherein said brace member is provided with a plurality of three dished portions.
