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.
