Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to light fixtures for mounting to ceilings and walls. More particularly, this invention relates to bracket assemblies that facilitate mounting of light and other fixtures to wall or ceiling-mounted electrical receptacle boxes.
2. Description of the Background Art
Presently, there exists many types of light fixtures that are designed to be ceiling or wall mounted. Typically, lights as well as other fixtures, are mounted over electrical receptacle boxes installed within the wall or ceiling such that the wiring of the fixture may be easily connected to the household wiring contained within the electrical receptacle box.
Various brackets have been designed for facilitating the mounting of lights and other fixtures to electrical boxes. The most common type of bracket consists of a mounting plate having holes that are dimensioned and aligned with the standardized threaded holes of the electrical receptacle box. Unfortunately, prior art brackets are often configured in such a manner that the bracket must first be mounted to the electrical box and then the fixture mounted to the bracket, both through the use of screws or other threaded fasteners. Consequently, there presently exists a need for a quick-install mounting bracket that facilitates the quick and easy installation of light and other fixtures to an electrical box installed within a wall or ceiling.
Therefore, it is an object of this invention to provide an improvement which overcomes the aforementioned inadequacies of the prior art devices and provides an improvement which is a significant contribution to the advancement of the wall or ceiling mounting bracket art.
Another object of this invention is to provide an electrical box bracket for allowing a light fixture to be easily mounted to an electrical box flush with the wall or ceiling in which the electrical box is installed.
Another object of this invention is to provide a quick install, flush-mount bracket for lights and other fixtures having one subbracket mounted to the electrical box and another subbracket mounted to the light fixture, with such subbrackets being easily coupled together such that the light fixture may be easily mounted to the electrical box flush with the wall or ceiling.
Another object of this invention is to provide a quick-install, flush mount bracket for lights and other fixtures that includes a first subbracket that may be mounted to or made integral with the electrical box and a second subbracket that may be mounted to or made integral with the light fixture with such subbrackets being easily coupled together such that the light fixture may be easily mounted to the electrical box flush with the wall or ceiling.
Another object of this invention is to provide a quick-install, flush mount bracket for lights and other fixtures that includes a first subbracket that may be mounted to the ceiling or wall and a second subbracket constructed integrally with or attached to the light fixture with such subbrackets being easily coupled together such that the light fixture may be easily mounted to the ceiling or wall.
Another object of this invention is to provide a quick-install, flush-mount bracket for lights and other fixtures that includes a first subbracket that may be pre-installed with the electrical box during construction and another subbracket that may be installed with the light fixture, possibly at the factory during manufacture, such that the light fixture can be easily installed without any particular expertise or tools on the part of the consumer.
The foregoing has outlined some of the pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
For the purpose of summarizing this invention, this invention comprises a quick-install, flush-mount bracket for lights and other fixtures. More particularly, the bracket of the invention is designed to facilitate the quick installation of a light or other fixture to an electrical box installed within a wall or ceiling in such a manner that the fixture is mounted flush with the wall or ceiling.
The bracket of the invention comprises numerous embodiments, each including complementary male and female subbrackets. One of the subbrackets is configured and dimensioned to be mounted to the threaded mounting holes of an electrical junction box (the spacing and thread of which are standardized throughout the industry). The other subbracket is configured to be mounted to the light or other fixture. The subbrackets are complementarily designed to be quickly fastened together such that the fixture may be quickly and easily mounted to the electrical box flush with the wall or ceiling in which the box is installed.
The invention's subbrackets may be sold as a kit and included with the light fixture or sold separately for use in conjunction with existing light fixtures. Alternatively, the subbracket connected to the fixture may be pre-installed at the factory during manufacture of the light fixture. Similarly, the subbracket to be mounted to the electrical box may be pre-mounted to the electrical box at the factory, or before, during, or immediately after construction of the wall or ceiling. In this manner, once the construction is completed (i.e., drywall installed and painted), the fixtures may be quickly and easily installed without any special expertise or tools.
Finally it is noted that for the purposes of the following description and the claims, the subbrackets may be respectively integrally formed with the light fixture and/or the electrical box to thereby eliminate the need for having separate components that must then be assembled together and therefore all references to subbrackets encompass being so integrally formed as well as being a separate component.
The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description of the invention that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 1-18
illustrate the various embodiments of the bracket assembly
10
of the invention designed to easily couple a light or other fixture
12
to a conventional electrical box receptacle
14
such that the fixture
12
may be flush-mounted to the ceiling or wall
16
in which the electrical box
14
is installed. In each embodiment, the bracket assembly
10
comprises a male subbracket
18
and a female subbracket
20
adapted for installation relative to the fixture
12
or electrical box
14
, respectively or vice versa, to facilitate easy flush-mount installation of the light fixture to the electrical box
14
.
FIGS. 1-5
illustrate the first embodiment of the bracket assembly
10
of the invention. In this first embodiment, the male subbracket
18
is mounted to the light fixture
12
and the female subbracket
20
is mounted to the electrical box
14
. More particularly, the male subbracket
18
comprises a generally inverted U-shaped mounting plate
22
having radially extending flanged legs
24
. The flanged legs
24
of the plate
22
serve to allow the mounting plate to be installed to the topside
12
T of the light fixture
12
by means of fasteners
26
such as threaded fasteners, rivets, or the like. A threaded stud
26
is coupled through a hole in the plate
22
and secured into position by opposing threaded nuts
30
A and
30
B, in such a manner that the threaded stud
26
extends upwardly from the plate
22
. However, it is noted that the subbracket
18
may be integrally formed with the light fixture
12
such that the threaded stud
26
is threaded directly to the light fixture
12
to thereby eliminate the need for having a separate plate
22
with flanged legs
24
that must then be assembled to the top surface
12
T of the fixture
12
.
The female subbracket
20
of the first embodiment comprises a generally flat mounting plate
32
having a center hole
32
H and a pair of mounting holes
34
at opposing ends thereof to allow the mounting plate
32
to be threadedly fastened to the threaded holes
36
of the electrical box
14
. In this regard, it is noted that the spacing of the threaded holes
36
, as well as their thread size, is standard throughout the industry. It is also noted that the mounting holes
34
of the mounting plate
32
of the invention may comprise slots as shown to facilitate the ease in which the mounting plate
32
can be mounted to the electrical box
14
via the screws
38
.
The female subbracket
20
further comprises a leaf plate
40
having opposing leafs
40
L circumscribing a center hole
40
H defined by longitudinal slots
40
L and transverse slots
40
T (see FIG.
5
), the center hole
40
H having a diameter appreciably less than the outer diameter of the threaded stud
28
. The leaf plate
40
is fastened to the mounting plate
32
by means of fasteners
42
such as threaded fasteners or rivets, such that the center hole
40
H of the leaf plate
40
is concentrically aligned with the center hole
32
H of the mounting plate
32
.
As shown in
FIG. 3
, the male subbracket
18
may be easily coupled to the female subbracket
20
by merely pushing the threaded stud
28
of the male subbracket
18
through the hole
32
H of the mounting plate
32
and then through the smaller diameter hole
40
H of the leaf plate
40
. During the initiation of such insertion, the opposing leafs
40
L defined by the slots
40
L and
40
T spread upwardly and partially away from each other to allow the threaded stud
28
to be fully installed therein. As shown in
FIG. 4
, upon full insertion of the threaded stud
28
of the male subbracket
18
into the female subbracket
20
, fixture
12
is flush-mounted to the ceiling or wall
16
in which the electrical box
14
is installed.
It is noted that the use of the threaded stud
28
and the leaf plate
40
compensates for any non-flush installation of the electrical box
14
relative to the surface of the ceiling or wall
16
. Specifically, in the event the electrical box
14
is improperly mounted somewhat recessed from the outer surface of the ceiling or wall
16
, the threaded stud
28
is still sufficiently long to penetrate the center hole
40
H of the leaf spring
40
to be retained thereby. Further, it is noted that any downward force exerted on the light fixture
12
after coupling, will merely result in the edges of the leaf plate
40
that define the hole
40
H, being forced into the troughs of the threads of the threaded stud
28
to even more fully enhance the respective coupling thereof Finally, it is noted that in the event the light fixture
12
may need to be removed, it could be removed by merely rotating the light fixture
12
in a counter-clockwise direction so as to unthread the threaded stud
28
from the leaf plate
40
(and indeed the leafs
40
L may be arcuately formed to better match the pitch of the thread to thereby facilitate unthreading). However, if the fixture is electrically wired to the household wiring contained within the electrical box
14
, removal is not permitted due to such wiring that would wrap around the threaded stub
28
during rotation. In such situations, the preferred removal method would comprise removal of the fasteners
26
of the flange legs
24
to release the fixture
12
, whereupon the threaded stud
28
of the male subbracket
18
may then be unthreaded from the leaf plate
40
.
The second embodiment of the bracket assembly
10
of the invention is disclosed in
FIGS. 6-14
. More particularly, the male subbracket
18
of the second embodiment of the bracket assembly
10
comprises a pair of downwardly-extending spring clips
44
, preferably composed of a spring steel, that engages into corresponding slots
46
formed in the female subbracket
20
. As shown in
FIGS. 6-8
, the male subbracket
18
including the spring clips
44
may be mounted to the electrical box
14
or, alternatively as shown in
FIGS. 9-11
, the male subbracket
18
may be formed integrally with the top side
12
T of the fixture
12
with the spring clips
44
extending upwardly therefrom for insertion into the female subbracket
20
mounted to the electrical box
14
.
More particularly, as shown in
FIGS. 6-8
, spring clips
44
each comprise a generally inverted U-shaped configuration having legs
48
. One leg
48
includes a plurality of indentations or teeth
48
T facing outwardly. The other leg
48
may likewise include outwardly facing teeth
48
T, but preferably is smooth-configured with its tip
48
P arced inwardly as shown. Each of the spring clips
44
is mounted to a mounting plate
52
(similar to mounting plate
32
of the first embodiment) for connection to the electrical box
14
through the use of mounting holes
34
and screws
38
, as described above in connection with mounting plate
32
of the first embodiment. Each of the spring clips
44
are securely connected to the mounting plate
52
in a spaced-apart configuration by means of fasteners
54
such as screws or rivets. As shown, the pair of spring clips
44
are oriented such that the teeth
48
T of their respective legs
48
face outwardly.
The female subbracket
20
of the second embodiment of the invention is formed integrally with the topside
12
T of the fixture
12
and comprises the paired slots
46
that are spaced apart from each other in alignment with the spaced-apart paired spring clips
44
. As best shown in
FIG. 7
, the length of each of the slots
46
is appreciably less than the outer dimensions of the legs
48
of the spring clips
48
. In this manner, when the spring clips
44
are aligned with the slots
46
, legs
48
must be resiliently squeezed inwardly during initial insertion of them into the slots
46
. As best shown in
FIG. 8
, this inward bending of the legs
48
cause the teeth
48
T of leg
48
to function as a ratchet as the spring clips
44
are further inserted into the slots
46
. Consequently, the fixture
12
may be easily mounted to the electrical box
14
flush with the surface of the ceiling or wall
16
even in situations in which the electrical box
14
is not itself precisely flush with the ceiling or wall
16
. It is noted that removal of the fixture
12
may be easily accomplished by simply squeezing the legs
48
together for each of the spring clips
44
until the teeth
48
T of the leg
48
is released from the edge of the slots
46
.
FIGS. 9-11
similarly illustrate the second embodiment of the bracket assembly
10
of the invention, but with the male and female subbrackets
18
and
20
being reversed. Specifically, as shown in
FIG. 9
, slots
46
of the female subbracket
20
may be formed within the mounting plate
32
mounted to the electrical box
14
. Conversely, spring clips
44
may be mounted via the fasteners
54
to the top side
12
T of the fixture
12
(such topside
12
T thereby functioning as the male subbracket
18
).
As shown in
FIG. 10
, the relative alignment of the spring clips
44
relative to the slots
46
allows the spring clips
44
to ratchet completely inwardly into the slots
46
such that the fixture
12
is flush-mounted to the ceiling or wall
16
(see FIG.
11
). It is noted that removal of the fixture
12
is rendered more difficult when the male subbracket
18
is mounted relative to the fixture
12
due to the inability to gain access to the legs
48
to squeeze them and cause them to release from the slots
46
of the female subbracket
20
. Accordingly, access holes
56
may be provided in the top side
12
T of the fixture
12
in alignment with the screws
38
to facilitate removal thereof and hence removal of the fixture
12
.
FIGS. 12-14
illustrate a modification to the second embodiment wherein the leg
48
includes a lip
48
L in lieu of the teeth
48
T as shown and described in connection with
FIGS. 6-11
above. As shown in
FIG. 13
, the spring clips
44
having the single lip
48
L include an outer diameter between the legs
48
that is appreciably less than the slots
46
such that the legs
48
have to be forced inwardly in order to be inserted into the slots
46
. As shown in
FIG. 14
, once inserted into the slots
46
, the lip
48
L of leg
48
engages underneath the edge of the slot
46
. Once the lips
48
L of the respective spring clips
44
are thus engaged, the fixture
12
is securely mounted relative to the electrical box
14
. However, unlike the versions shown in
FIGS. 6-11
, the single lip
48
L of leg
48
does not provide the degree of adjustability as was described above in connection with the teeth
48
T of leg
48
of the spring clips
44
of
FIGS. 6-11
. Finally, it is noted that without departing from the spirit and scope of this invention, the configuration shown in
FIGS. 12-14
may be reversed similar to that of
FIGS. 9-11
.
Finally,
FIGS. 15-18
illustrate the third embodiment of the bracket assembly
10
of the invention. This third embodiment is similar to that of the second embodiment of
FIGS. 6-14
, but in lieu of the paired spring clips
44
shown in connection therewith, this third embodiment includes a male subbracket
18
having a single spring clip
60
. The spring clip
60
includes a generally inverted U-shaped configuration with legs
62
. Each of the legs
62
further include an outwardly extending extension
66
having an inturned end
68
. Preferably, the extensions
66
to the legs
62
extend substantially radially outwardly as shown in FIG.
15
. The spring clip
60
is connected to the male subbracket
18
by means of a fastener
72
such as a threaded fastener or rivet. The mounting plate
70
is connected to the electrical box
14
by means of screws
38
in the manner described above.
The female subbracket
20
of the third embodiment is similarly integrally formed in the topside
12
T of the fixture
12
and comprises a pair of slots
74
dimensioned so as to receive the extensions
66
of legs
62
.
In order to facilitate insertion of the extensions
66
into the slots
74
, a squeeze plate
76
is provided. The squeeze plate
76
comprises a generally elongated design having slots
78
at its ends for receiving the respective extensions
66
of legs
62
, with the respective centers of slots
78
being approximately equal to the relaxed distance between the leg
62
(see FIG.
15
). To facilitate assembly, the squeeze plate
76
is slid downwardly along the legs
62
and their extensions
66
to the inturned end
68
thereby causing extensions
66
to be squeezed together to a generally parallel configuration as shown in
FIG. 16
with the squeeze plate
76
being retained by the inturned ends
68
. As such, as shown in
FIG. 17
, the now parallel-positioned extensions
66
are in alignment with the respective slots
74
so that the extensions
66
may be inserted therein. As shown in
FIG. 18
, as the fixture
12
is forced upwardly, the squeeze plate
76
is likewise forced upwardly allowing the extensions
66
to return to their original non-parallel, radially-outwardly extending configuration. The fixture
12
is thus secured relative to the electrical box
14
flush with the ceiling or wall
16
in which the box
14
is installed. However, it is noted that fixture
12
may be removed by squeezing on the inturned ends
68
of the extensions
66
of the legs
62
to force them into a generally parallel alignment thereby releasing the fixture
12
.
In each of the embodiments of the bracket assembly
10
of the invention, a tether, generally indicated by numeral
80
, may be provided to interconnect the male subbracket
18
and the female subbracket
20
. While many embodiments of the tether may suffice, a preferred tether
80
comprises one end having a T-bar configuration for insertion within a hole
82
formed in one of the subbrackets
18
or
20
and the other end of the tether
80
may be permanently affixed to the other subbracket
20
or
18
(see FIGS.
1
&
2
). In this manner, the T-bar end
82
of the tether
80
may be easily coupled to the subbracket
18
or
20
allowing the fixture
12
to hang therefrom. While hanging, the fixture
12
may be conveniently wired to the electrical household wiring contained within the electrical box
14
.
The present disclosure includes that contained in the appended claims, as well as that of the foregoing description. Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
Now that the invention has been described,
