Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a mounting device for mounting a speaker enclosure or cabinet in an elevated position at a vertical or horizontal intersection of two walls, a wall and a ceiling, or similar structures, wherein the device facilitates easily locating supportive studs underlying surface sheathings, and is adapted to couple with and support the speaker enclosure in such a manner as to allow for dismounting and remounting the speaker enclosure from or on the device without dismounting the device itself from the structures.




2. Description of the Prior Art




Those with skill in the art of home audio or theater systems and speaker enclosures or cabinets will appreciate that it is often desirable to mount a speaker enclosure in an elevated position at a vertical or horizontal intersection of two walls, a wall and a ceiling, or similar structures. Unfortunately, a number of problems are encountered when attempting to do so, including difficulty locating studs or similar structures capable of supporting the speaker enclosure and a mounting mechanism, and difficulty and inconvenience in dismounting and remounting the speaker enclosure for maintenance or replacement.




The studs are constructed of wood or metal for supporting the walls, and typically spaced between twelve and twenty-four inches apart depending on a number of factors, including use and load bearing requirements. Each wall is framed with corner studs, such that an intersection of the walls results in first and second perpendicularly-oriented closely spaced or abutting studs. The studs are covered with a sheathing such as, for example, sheet rock or wood paneling. The wall sheathing is typically unsuitable for supporting substantial loads, such as the speaker enclosure, so any such load mounted on the surface must be secured to one or more underlying studs for reliable support. Unfortunately, it will be appreciated, locating the studs hidden beneath the sheathing can be very difficult. Furthermore, fasteners driven into the an improperly located stud may split or otherwise damage the stud and fail to provide the desired support.




Additionally, recent developments in home theater systems have resulted in speaker enclosures that are larger and heavier than those previously used, thereby making the mounting thereof even more difficult. The speaker enclosures have become larger in order to house more complex crossover networks and bigger speaker magnets, which provide improved control over speaker cone movement. Furthermore, speaker enclosures have become heavier due to use of heavier materials from which the speaker enclosures are constructed, with the heavier speaker enclosures providing improved bass response and reduced resonance.




Once properly mounted, it may at some point become necessary to dismount the speaker enclosure for maintenance or replacement, after which the same or a different speaker enclosure must be remounted. Unfortunately, many existing mounting schemes do not allow for convenient dismounting and remounting, and some require that the mounting mechanism itself be dismounted and remounted or that the fasteners be withdrawn and reapplied to the studs. It will be appreciated that either action can result in damage to the sheathing or the studs and may ultimately undermine their supportive qualities and cause structural failure.




Due to the above-identified and other problems and disadvantages in the art, a need exists for an improved speaker mounting mechanism.




SUMMARY OF THE INVENTION




The present invention overcomes the above-identified and other problems and disadvantages in the art to provide a mounting device for mounting a speaker enclosure or cabinet in an elevated position at a vertical or horizontal intersection of two walls, a wall and a ceiling or similar first and second structures, wherein the device facilitates easily locating supportive studs hidden beneath surface sheathings, and is adapted to couple with and support the speaker enclosure in such a manner as to allow for conveniently dismounting and remounting the enclosure from and on the device without dismounting the device itself from the walls.




The preferred mounting device comprises a corner bracket and an upper and a lower mounting plate. The corner bracket presents a substantially triangular cross-section, is made of aluminum, plastic, or a similarly suitable material, and, in a preferred embodiment, presents five surfaces. The first and second surfaces are corner-facing surfaces and intersect each other at an approximate 150° angle. The third and fourth surfaces are wall-facing and intersect the first and second surfaces, respectively, at approximate 150° angles. The fifth surface is speaker-facing and intersects the third and fourth surfaces at approximate 45° angles, thereby completing and closing the substantially triangular corner bracket. The speaker-facing surface is oriented substantially perpendicular to a plane bisecting the intersection of the walls and provides a coupling mechanism whereby the speaker enclosure may be removably coupled with the mounted corner bracket. In a preferred embodiment, the coupling mechanism comprises an upper and a lower elongated slot or groove in the speaker-facing surface and operable to removably receive upper and lower fasteners associated with the upper and the lower mounting plates.




The mounting plates are secured to a rear portion of the speaker enclosure and incorporate or receive the fasteners. The fasteners may be any suitable coupling mechanism, such as, for example, threaded bolts or fixed mounting posts. Various alternative embodiments of both the corner bracket and the mounting plates are possible, a representative sample of which are presented herein.




In operation, the corner bracket is positioned at the intersection of two walls or a wall and a ceiling. Fasteners driven into holes provided in the corner-facing surfaces automatically align with the underlying corner studs, thereby ensuring proper support. The wall-facing surfaces will abut the walls, and cutouts let into the wall-facing surfaces will correspond to holes in the walls wherethrough speaker wires are able to exit the walls, enter the an interior portion of the corner bracket, and connect to the rear portion of the speaker enclosure. The mounting plates will have been attached to the speaker enclosure using wood screws or an equivalent means. Thereafter, the enclosure may be lowered onto the speaker-facing surface of the bracket such that the upper and lower fasteners are securely received within the elongated grooves. The fasteners are then tightened to complete the mounting process. Dismounting the speaker enclosure is easily accomplished by loosening or removing the fasteners and lifting the enclosure from the mounted bracket.




Thus, it will be appreciated that the present invention offers a number of advantages over the prior art, including a mechanism whereby the corner studs are automatically and reliably located. Furthermore, once mounted, the speaker enclosure may be easily dismounted by loosening the bolts and lifting the enclosure from the corner bracket, without having to dismount the corner bracket itself.




These and other important aspects of the present invention are more fully described in the section entitled DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT, below.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT




Referring to

FIGS. 1

,


2


, and


3


, a speaker mounting device


10


is shown constructed in accordance with a preferred embodiment of the present invention, and operable to mount a speaker enclosure


12


in an elevated position at an intersection of two walls


14


,


16


, a wall and a ceiling, or similar structures, wherein the device


10


facilitates easily locating supportive wall studs


18


,


20


underlying wall sheathings


22


,


24


, and the device


10


is adapted to couple with and support the speaker enclosure


12


in such a manner as to allow for dismounting and remounting the speaker enclosure


12


from and on the device


10


without dismounting the device itself from the walls


14


,


16


. The preferred speaker mounting device


10


broadly comprises a corner bracket


26


; an upper mounting plate


28


, including an upper fastener


30


; and a lower mounting plate


32


, including a lower fastener


34


.




The corner bracket


26


is operable to both facilitate properly engaging the wall studs


18


,


20


and to couple with and support the speaker enclosure


12


using the upper and lower mounting plates


28


,


32


. The bracket


26


is preferably constructed of 0.125 inch aluminum, though, alternatively, any similarly suitable material maybe used; the bracket's size will depend on the size and weight of the enclosure


12


being mounted, with a larger enclosure


12


requiring a larger bracket


26


. The corner bracket


26


presents a number of angled surfaces, including first and second corner-facing surfaces


38


,


40


; first and second wall-facing surfaces


42


,


44


; and a speaker-facing surface


46


.




The first and second corner-facing surfaces


38


,


40


are each substantially identical to the other, being an elongated rectangle providing a plurality of through holes


51


,


52


spaced approximately 3.25 inches apart. The holes


51


,


52


allow #10 wood screws


54


,


56


to pass therethrough, through the wall sheathings


22


,


24


, and into the wall studs


18


,


20


, thereby securing the corner bracket


26


. The corner-facing surfaces


38


,


40


intersect one another at a 150° degree angle


50


such that screwing the wood screws


54


,


56


into the wall sheathings


22


,


24


perpendicular to the corner-facing surfaces


38


,


40


will automatically properly locate and screw into the wall studs


18


,


20


.




The first and second wall-facing surfaces


42


,


44


are each substantially identical to the other, being an elongated rectangle providing a plurality of spaced apart cutouts


60


each approximately 0.50 inches wide by 1.75 inches long. The cutouts


60


allow easier access for speaker wires


66


exiting the sheathings


22


,


24


. The wall-facing surfaces


42


,


44


intersect respective corner-facing surfaces


38


,


40


at a 150° angle


62


,


64


such that the wall-facing surfaces


42


,


44


parallel and lay flat against the wall sheathings


22


,


24


while the corner-facing surfaces


38


,


40


maintain a proper angle for screwing into the wall studs


18


,


20


.




The speaker-facing surface


46


parallels a rear surface


70


of the speaker enclosure


12


, and intersects each wall-facing surface


42


,


44


at a 45° angle


72


,


74


such that the speaker-facing surface


46


is perpendicular to a line bisecting the intersection of the two walls


14


,


16


. The speaker-facing surface


46


provides a large center cutout


78


and upper and lower elongated grooves


80


,


82


. The center cutout


78


allows for access to the rear


70


of the speaker enclosure


12


, and may be surrounded partially or wholly by flanges


84


,


86


which provide stiffness to the speaker-facing surface


46


and reduce deflection thereof when tightening the speaker enclosure


12


thereto.




The elongated grooves


80


,


82


are 0.50-1.00 inches deep and operable to receive the first and second fasteners


30


,


34


. In this embodiment of the corner bracket


26


, the grooves


80


,


82


open in different directions—the upper groove


80


opens upward and the lower groove


82


opens downward. An advantage of this symmetry is that the cornerbracket


26


requires no necessary mounting orientation, thereby eliminating a major cause of improper mounting and subsequent work required to dismount, reorient, and remount the bracket


26


.




Referring to

FIG. 4

, an alternative embodiment of the corner bracket


226


is shown substantially similar to the embodiment


26


described above, but having the upper and lower elongated grooves


280


,


282


opening in substantially the same direction. A cutout


263


is made in the lower flange


285


to pass the lower fastener


234


when the speaker enclosure is set upon the bracket


226


. An advantage of this alternative embodiment


226


is that both fasteners


230


,


234


can be started and received within the grooves


280


,


282


when the speaker enclosure is set upon the bracket


226


. This is particularly advantageous where the mounting intersection is horizontally oriented, as the two fasteners


230


,


234


once received within the grooves


280


,


282


will support the speaker enclosure substantially in its mounted position while the fasteners


230


,


234


are tightened.




Referring also to

FIGS. 5 and 6

, the upper and lower mounting plates


28


,


32


are each operable in cooperation with the first and second fasteners


30


,


34


to support and retain the speaker enclosure


12


on the mounted corner bracket


26


. Each plate


28


,


32


comprises a substantially flat elongated rectangular piece


86


,


88


, constructed of aluminum or a similarly suitable material able to safely support the speaker enclosure's weight. The rectangular piece


86


,


88


provides a plurality of screw holes


90


for receiving wood screws


92


for securing the rectangular piece


86


,


88


to the rear portion


70


of the speaker enclosure


12


. Furthermore, projecting perpendicularly from and corresponding to a hole


94


in the center of each rectangular piece


86


,


88


is an internally threaded sleeve


96


operable to receive the upper and lower fastener


30


,


34


. The sleeve


96


fits into a corresponding hole


97


let into the rear portion


70


of the speaker enclosure


12


.




The upper and lower fasteners


30


,


34


are preferably 1.00 inch long, 0.625 inch diameter threaded bolts operable to screw into the internally threaded sleeves


96


of the mounting plates


28


,


32


, and thereafter to be received within the elongated grooves


80


,


82


of the speaker-facing surface


46


of the corner bracket


26


.




It will be appreciated that numerous variations of the mounting plates


28


,


32


and fasteners


30


,


34


exist which are within the scope of the present invention. For example, an alternative embodiment of the mounting plates


228


,


232


and fasteners


230


,


234


is shown in

FIG. 7

, wherein the sleeve


296


,


298


extends through the rectangular pieces


286


,


288


to present a sufficient portion


297


,


299


of the sleeve


296


,


298


so as to ensure a particular desired spacing between the rectangular pieces


286


,


288


and the speaker-facing surface


46


of the corner bracket


26


. Alternatively, this same embodiment, rather than ensuring spacing, may be used to protect the threads of the threaded fasteners


230


,


234


by allowing the additional sleeve portion


297


,


299


rather than the fasteners


230


,


234


to contact and rest within the elongated groove


80


,


82


. This latter embodiment requires that the elongated groove


80


,


82


be dimensioned to accommodate the wider sleeve portion


297


,


299


.




Another alternative embodiment


428


,


432


is shown in

FIG. 8

, wherein the fastener is a fixed mounting post


430


,


434


rather than a threaded bolt. The fixed post


430


,


434


may be welded or otherwise secured to the rectangular piece


486


,


488


, and is removably receivable within the elongated groove


80


,


82


. Though not adjustable, the fixed post


430


,


434


operates substantially similar to the threaded bolt embodiment


30


,


34


. Because the post


430


,


434


cannot be tightened, it may be desirable to coat the rectangular piece


486


,


488


with a rubber or similar coating


502


,


504


in order to substantially lessen or eliminate vibrations caused by the operating speaker enclosure


12


.




As desired, the speaker enclosure or cabinet may be shaped to further accommodate the walls


12


,


14


and intersection thereof as shown in

FIGS. 1 and 2

, wherein the speaker enclosure is provided with beveled surfaces


98


,


100


. Alternatively, the speaker mounting device


10


may be dimensioned to provide sufficient clearance for conventional unbeveled speaker enclosures.




In operation, an installer positions the corner bracket


26


as desired at the intersection of two walls


14


,


16


, with the wall-facing surfaces


42


,


44


resting flatly against the wall sheathing


22


,


24


. The wood screws


54


,


56


are then screwed perpendicularly through the screw holes of the corner-facing surfaces


38


,


40


, thereby properly entering into and securely engaging the wall studs


18


,


20


.




Next, both upper and lower mounting plates


28


,


32


are attached to the rear portion


70


of the speaker enclosure


12


by fitting the sleeves


96


,


98


into the respective corresponding holes


97


, and screwing wood screws


92


through the screw holes


90


. Using the corner bracket embodiment


26


of FIG.


3


and the mounting plate embodiment


28


,


32


of

FIGS. 5 and 6

, the upper threaded fastener


30


is then partially screwed into the upper internally threaded sleeve


96


. The enclosure


12


is then lowered onto the mounted corner bracket


26


so that the upper threaded fastener


30


is received within the upper elongated groove


80


; then the upper fastener


28


is tightened. The lower threaded fastener


32


is then screwed through the lower elongated groove


82


, into the lower sleeve


98


, and tightened to complete the mounting procedure. The speaker enclosure


12


may be easily dismounted by removing the lower fastener


34


, loosening the upper fastener


30


, and lifting the enclosure off the bracket


26


.




Alternatively, using the corner bracket embodiment


226


of FIG.


4


and the mounting plate embodiment


428


,


432


of

FIG. 8

, the enclosure


12


is mounted on the bracket


226


by lowering the mounting posts


430


,


434


of the attached rubber-coated mounting plates


428


,


432


into the upper and lower elongated grooves


80


,


82


, and applying sufficient force to seat the posts


430


,


434


therein. Dismounting the speaker enclosure


12


is accomplished by applying sufficient upward force to unseat the mounting posts


430


,


434


from the elongated grooves


80


,


84


and lifting the enclosure


12


away from the bracket


226


.




From the preceding description, it can be seen that the speaker mounting device


10


of the present invention is operable to mount the speaker enclosure


12


in an elevated position at an intersection of two walls


14


,


16


or similar structures, wherein the device


10


facilitates easily locating the supportive wall studs


18


,


20


, and is adapted to couple with and support the speaker enclosure


12


in such a manner as to allow for removing and replacing the speaker enclosure


12


from or on the device


10


without removing the device itself from the walls


14


,


16


.




Although the invention has been described with reference to the preferred embodiment illustrated in the attached drawings, it is noted that equivalents may be employed and substitutions made herein without departing from the scope of the invention as recited in the claims. For example, as noted, a variety of mounting plate and fastener configurations may be devised and used for removably coupling the enclosure


12


with the corner bracket


26


. Such alternative configurations are within the scope of the present invention.
