Spotlight bracket for a false ceiling or a false wall

A spotlight bracket for a false ceiling or false wall constituted by a stretched sheet hooked, along its edges, to a support fixed to the wall or to the ceiling, comprises two parts adjustable with respect to each other, namely an upper part fixed to the ceiling and a lower part adjustable in height and in inclination with respect to the fixed upper part. The upper part, in the form of a downwardly open fork-joint, comprises an upper horizontal web fixed to the ceiling or wall. This web is pierced with a hole for the passage of an electric cable and it is fast, at its two ends, with two vertical, downwardly extending arms. The adjustable lower part, which is also in the form of a fork-joint open upwardly, comprises a lower horizontal base plate fast with two opposite vertical arms extending upwardly and which tighten on the arms of the fixed upper fork-joint.

BACKGROUND OF THE INVENTION 
The present invention relates to a spotlight bracket for a false ceiling or 
false wall constituted by a stretched sheet fastened, along its edges, to 
a support fixed to the wall or ceiling. 
False ceilings are already known which comprise, on the one hand, a 
horizontal frame fixed to the upper part of the walls of a premises, this 
frame being formed by an outer longitudinal member itself constituted by 
butt-jointed sections and, on the other hand, a sheet stretched 
horizontally within this frame, this sheet being constituted by a sheet of 
plastics material or a fabric cloth. The sheet is maintained stretched due 
to the fastening, on the longitudinal member, of an edge integral with the 
sheet, forming to some extent a "harpoon", this edge presenting in cross 
section the form of a hook hooking on a shoulder of the longitudinal 
member. 
Such known false ceilings are often used with a spotlight which is housed 
in a support or bracket fixed to the ceiling and/or to the wall between 
them and the sheet. Where a spotlight is mounted, the sheet is cut out so 
as to present an opening of diameter corresponding substantially to that 
of the spot, in order to allow the room in which the false ceiling or the 
false wall is mounted, to be illuminated. 
SUMMARY OF THE INVENTION 
The present invention relates to a spotlight bracket of particularly simple 
design which allows simple assembly whatever the implantation of the 
installation. 
To that end, this spotlight bracket for use in a false ceiling or false 
wall constituted by a stretched sheet hooked, along its edges, to a 
support fixed to the wall or to the ceiling, comprises two parts 
adjustable with respect to each other, namely an upper part fixed to the 
ceiling and a lower part adjustable in height and in inclination with 
respect to the fixed upper part. 
The stretched sheet may be connected to oppositely facing walls by any 
suitable conventional means. One such example of a suitable means is shown 
in Scherrer, U.S. Pat. No. 4,408,433. The aforesaid U.S. patent also 
refers to other prior art disclosing material or cloth maintained 
stretched inside a frame which is fixed to the top of the walls of a room.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
Referring now to the drawings, FIG. 1 shows a spotlight bracket 1 according 
to the invention which is disposed between a ceiling 2 and a stretched 
sheet 3 (schematically shown) extending horizontally and constituting a 
false ceiling. The spotlight bracket 1 according to the invention 
comprises two parts adjustable with respect to each other, namely an upper 
part 4 fixed to the ceiling 2 and a lower part 5 which is adjustable in 
height and inclination with respect to the fixed upper part 4. The upper 
part 4, in the form of a downwardly open fork-joint, comprises an upper 
horizontal web 6 which may be constituted by a piece of wood, this web 6 
being fixed to the ceiling 2. The web 6 is pierced with a hole 7 for the 
passage of an electric cable 8. The web 6 is fast, at its two ends, with 
two vertical arms 9, 10 extending downwardly. 
Furthermore, the adjustable lower part 5 which is also in the form of an 
upwardly open fork-joint, comprises a lower horizontal base plate 11 fast 
with two opposite vertical arms 12 and 13 extending upwardly and which 
tighten on arms 9,10 of the fixed upper fork-joint 4. The base plate 11 
which may have a contour of any form, for example polygonal as shown in 
FIG. 2, is pierced at its centre with a hole 14 for the passage of a bulb 
15 of the spotlight borne by bracket 1. The stretched sheet 3 is for its 
part also pierced with a hole 16, in registry with hole 14 of the base 
plate 11, and it preferably bears, on its upper face and around hole 16, a 
reinforcing washer 17 glued thereto. 
The vertical arms 9, 12 on the one hand and 10,13 on the other hand, are 
assembled together so as to form assemblies adjustable in length and in 
inclination. Such adjustments are obtained thanks to the presence of 
oblong vertical slots 18 in arms 9,10,12,13 and of locking elements 19, 
for example of the butterfly nut type, engaged in the oblong slots 18. 
FIG. 3 illustrates the use of a spotlight bracket according to the 
invention when the spotlight is to be placed in an inclined plane. In that 
case, the lower part 5 of the bracket 1 is inclined by the appropriate 
angle with respect to the upper vertical part 4 fixed to ceiling 2. 
A tube 20 may possibly be disposed inside the bracket 1, in abutment on 
plate 11 and surrounding the spotlight in order to form a screen with 
regard to the light radiated upwardly.
