The present invention refers to a support frame for flush-fit light fitting.
Flush-fit light fittings in holes in false ceilings are known from the
Flush-fit light fittings are usually produced industrially in series according to the type of lamp that will be mounted. In particular the outside casing will have different openings, in terms of dimensions, number and shape, according to whether the lamp intended for it needs a single or a double fixture. A lamp-holder support is also needed to fasten the lamp, which obviously will vary in accordance with the lamp itself.
Therefore for each lamp, with different shape and dimension, it is necessary to have various types of external casings and lamp-holder supports.
The object of the present invention is to industrially produce a support frame for flush-fit light fittings that is adaptable to different types of lamp, whether they are single-capped or dual-capped.
In accordance with the invention this object is achieved with a support frame as disclosed in claim 1.
The industrial production of the frame according to the present invention leads to considerable economic advantages, as the same frames can be used for different types of lamp.
These and other characteristics of the present invention will be made more evident by the following detailed description of two embodiments thereof, illustrated as non-limiting example in the enclosed drawings, in which:
In a first embodiment (
Said external perimeter 2, circular, not flat and of varied thickness, has holes 17 and supports a cavity 3, inside which a terminal block 4 is fitted. The external perimeter 2 can also be polygonal.
The diametrical bridges 5 and 6 have at one end, with angular distance of 120°, fixing devices 8 (
The diametrical bridges 5 also have holes 15, jumpers 19, internally threaded holed protuberances 20 and hollow supports 22. Said hollow supports 22 house lamp holder fixtures 23 for a dual-capped lamp 31 (
Said lamp holder fixtures 23 are inserted into windows 27 made in an external casing 28 of the light fitting 50, which is made integral with the base flange 16 by means of a screw fixing system 30.
One of the two diametrical bridges 5 can for example be used for lamp holder fixtures 23 of a 150 Watt iodide lamp (
The frame 1 can also be used for single-capped lamp (
A second embodiment (
These small differences are due to the smaller dimensions of the light fitting 50 and therefore of said second frame 1. In fact it is problematical to add the other diametrical bridges 5-6.
The methods of using the two embodiments of the frame 1 are quite simple. Once said frame 1 has been produced by moulding in a plastic material the springs 11 are inserted, with respective levers 12, in the specific cavities 10 of the fixing devices 8.
When the lamp to be used has been chosen the lamp holder fixtures 23 and 21, the outside casing 28 and the base flange 16 are assembled, using mainly the screw-on fixing systems.
The wires (not shown in the figures) that connect the lamp holder fixtures 23 and 21 with the terminal block 4 are passed through the holes 15 and under the jumpers 19 thus enabling the wires themselves to remain together avoiding problems of excessive cluttering.
The terminal block 4 is finally inserted into the cavity 3.
The light fitting is now ready to be installed on any false-ceiling.
It is therefore easy to understand the great flexibility in the choice of the frame 1 (different embodiments), and above all the variety of the type of support to be used for the lamp holder fixtures 23 and 21 for each frame 1 in accordance with the type of lamp used.
