APPAREIL D'ECLAIRAGE POUR MONTAGE AU PLAFOND, AU MUR OU AUTRES SURFACES DU GENRE

LIGHT FIXTURE FOR MOUNTING TO A CEILING, WALL OR THE LIKE

Abrégé anglais

The disclosure herein describes a light fixture
for mounting to a ceiling, wall or the like which
comprises a pot having a peripheral edge abutting the
area adjacent a hole made in the ceiling or wall. A hook
and a bolt extending through appropriate openings in the
inner wall and the side wall of the pot cooperate to
secure the pot to the ceiling. Rotating the bolt causes
the hook to move into an abuting engagement with the rear
surface of the ceiling, the latter thus being contacted,
on the outside, by the peripheral edge of the pot and, on
the inside, by that portion of the hook engaging the rear
surface of the ceiling.

FIBLD OF THE lNV~ lON
The present invention pertains to a light
fixture for mounting to a ceiling, wall or the like in
which a hole has been made to receive the fixture.



BACRGROUND OF THE lNV~N.lON
There are various fastening devices to mount a
light fixture, in the form of a pot, to a ceiling or the
like. With those using a spring arrangement, the fixing
is accomplished inside the hole. Other systems require
a metallic plate inside the ceiling which results in an
electrician to work inside the ceiling to carry out the
mounting operation. Other devices require the provision
of a lath to which the pot is fixed. It has been found
that, in most cases, to secure the pot to the ceiling
often causes some damage to the material of the ceiling.



OBJECTS AND STATEMENT OF THE l~v~NlION
It is an object of the present invention to
overcome present problems of existing systems for fixing
a light fixture to a ceiling, wall or the like.



It is also an object of the present invention
to provide a mounting device which is easy to use and

which may be installed independently of the thickness of
the ceiling or wall.

~ - 2 - 2088648


This is achieved by providing a light fixture
which comprises:
- a pot, having an inner wall and a side wall,
adapted to be received rearwardly of the ceiling, the
side wall having an outer peripheral flange adapted to
bear against the front surface adjacent the opening; the
side wall defining slot means therein;
- a hook consisting of an elongated body
having a main portion adapted to extend through the slot
means substantially parallel to the side wall of the pot,
the body having a first end portion bent to extend
substantially parallel to the inner wall of the pot and
a second end portion bent to extend substantially
parallel to and rearwardly of the rear surface of the
ceiling; the first end portion defining a threaded hole
therethrough;
- a bolt having a head and an elongated
threaded stem adapted to extend through the opening of
the inner wall and to engage the threaded hole of the
first end portion of the hook whereby rotation of the
bolt causes the first end portion to move longitudinally
along the stem of the bolt and the second end portion to
move to bear against the rear surface of the ceiling to
thereby secure the light fixture to the ceiling.



In one form of the invention, the side wall of
the pot is provided with two vertically aligned slots
through which extend upper and lower parts of the hook.

In a further form of the invention, the lower
bent end portion of the hook as an enlarged width
relative to that of the rest of the hook to augment the
abutting function.



Other objects and further scope of
applicability of the present invention will become
apparent from the detailed description given hereinafter.
It should be understood, however, that this detailed
description, while indicating preferred embodiments of
the invention, is given by way of illustration only,
since various changes and modifications within the spirit
and scope of the invention will become apparent to those
skilled in the art.



IN THE DRAWINGS
Figure 1 is a cross-sectional view of a pot
forming part of the light fixture made in accordance with
the present invention;
Figure 2 is a perspective view of a hook
forming part of the light fixture of the present
invention;
Figures 3 and 4 show successive operations for
securing the light fixture to a ceiling.




DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to figure 1, there is shown a pot 10
having an inner wall 12 and a sidewall 14, the latter

20B864 8


having a peripheral outer flange 16 which is adapted to
bear against the front surface 18 of a ceiling 20.



The side wall 14 displays a pair of slots 22
and 24 vertically aligned with respect to one another,
S the lower slot having an enlarged lower section 26. As
can be seen in figure 3, the inner wall 12 has an opening
28.



Referring to figure 2, a hook, generally
denoted 30, defines an elongated rectangular body 32
having, at respective opposite ends thereof, a first bent
portion 34 and a second bent portion 36, both extending
substantially perpendicular to the main portion of body
32, which consists of an upper part 32a, an intermediate
part 32b and a lower part 32c.



Referring to figure 3, the light fixture also
comprises a bolt 40 having a head 42 and an elongated
threaded stem portion 44 which extends through the
opening 28 of the inner wall of the pot. This portion 44
threadingly engages hole 38 of the hook.




To secure the pot into the opening of the
ceiling, the bent portion 34 is inserted into slot 22
while bolt 40 is inserted in opening 28 and is threadedly
engaged in hole 38 of the bent portion 34. The lower
bent portion 36 is inserted into slot 26 so that parts

-- 5


32c and 32a of the hook lie rearwardly of the wall 14 of
the pot while part 32b extends inside the pot. The bolt
is rotated until the hook reaches the position shown in
figure 4 where the enlarged lower bent portion 36 abuts
the rear surface of the ceiling, thus securing the pot in
the ceiling opening.



Although the invention has been described above
with in relation to one specific form, it will be evident
to a person skilled in the art that it may be modified
and refined in various ways. It is therefore wished to
have it understood that the present invention should not
be limited in scope, except by the terms of the following
claims.
