Description




TECHNICAL FIELD




The present invention relates to fireplaces. More particularly, the invention relates to an adjustable support for a fireplace.




BACKGROUND




Fireplaces have become increasingly commonplace in homes, businesses, and other buildings. A fireplace may provide many benefits, including the creation of heat and an aesthetically-pleasing arrangement of flames and sounds. A variety of different types of fireplaces are available, including solid-fuel, gas, and electric. Each type of fireplace is typically mounted in an enclosure defined by a wall of a structure.




When installing a fireplace, additional support for the fireplace may be needed. For example, when a fireplace is installed into an existing enclosure in a wall of a structure, the enclosure may be too small to accommodate the entire fireplace, and a front of the fireplace may therefore extend beyond the enclosure and need additional support. Further, some fireplaces may be designed to extend out of the wall. In addition, it is sometimes desirable to install a fireplace at a given height, and support may be needed to maintain the fireplace at the desired height.




The height at which support for a fireplace may be needed can vary from installation to installation. Current support systems for fireplaces are not easily configurable and must typically be custom-made for a particular installation.




Therefore, it would be desirable to create an adjustable support structure for a fireplace.




SUMMARY




Generally, the present invention relates to fireplaces. More particularly, the invention relates to an adjustable support for a fireplace.




In one respect, the invention relates to an adjustable support structure for a fireplace including upper and lower bars extending in a longitudinal direction, the upper bar being positioned above the lower bar in a plane and the upper bar defining a surface upon which the fireplace can rest, and first and second cross bars, each with upper and lower ends, the upper end of the first cross bar being coupled to the upper bar and the lower end of the second cross bar being coupled to the lower bar, and wherein the lower end of the first cross bar is moveably coupled to the lower bar and the upper end of the second cross bar is moveably coupled to the upper bar such that the upper bar may be adjusted upwards in the plane with respect to the lower bar to a desired height.




In another aspect, the invention relates to an adjustable support structure for a fireplace including upper and lower bars, each extending in a longitudinal direction and each defining at least one aperture, the upper bar being positioned above the lower bar in a plane, and a scissor assembly including first and second cross bars, each with upper and lower ends and coupled to one another at about a midpoint of the first and second cross bars, the upper end of the first cross bar being coupled to a second end of the upper bar and the lower end of the second cross bar being coupled to a second end of the lower bar, and wherein the lower end of the first cross bar is moveable in the longitudinal direction towards the lower end of the second cross bar and the upper end of the second cross bar is moveable in the longitudinal direction towards the upper end of the first cross bar such that the upper bar is adjusted upwards in the plane with respect to the lower bar to a desired height and the lower end of the first cross bar may then be coupled to the at least one aperture of the lower bar and the upper end of the second cross bar may be coupled to the at least one aperture of the upper bar.




In yet another aspect, the invention relates to a method for adjusting a support structure for a fireplace including steps of: providing the support structure including upper and lower bars, a scissor assembly, and a surface for supporting the fireplace; adjusting the adjustable support to a desired height; and coupling the scissor assembly to the bars to lock the adjustable support at the desired height.




In another aspect, the invention relates to a method for supporting a fireplace including steps of: providing an adjustable support structure; adjusting the adjustable support structure to a desired height; and placing the adjustable support structure below the fireplace to support the fireplace.

DETAILED DESCRIPTION




The invention relates to fireplaces. More particularly, the invention relates to an adjustable support for a fireplace. While the present invention is not so limited, an appreciation of the various aspects of the invention will be gained through a discussion of the examples provided below.




Example adjustable support structures made in accordance with this invention may generally include a scissor assembly having a set of bars coupled to a set of cross bars. In addition, a second set of bars and cross bars may be coupled to the first set of bars at an angle. A second scissor assembly may also be provided. Trim may be coupled to the scissor assemblies. Various embodiments of the present invention are described below.




I. Support Structure Components




Referring now to

FIG. 1

, a first embodiment of an example adjustable support structure


100


for a fireplace is shown in exploded form. The adjustable support structure


100


generally includes two scissor assemblies


200


and top, front, and side trims


800


,


900


, and


1000


. The adjustable support structure


100


may be adjusted in height depending on the requirements for support of a fireplace. For example, in one embodiment, the adjustable support structure


100


can be adjusted from 2 inches to 10 inches in height. However, any desired range of height can be used without departing from the spirit of the invention.




Referring now to

FIGS. 2-4

, one scissor assembly


200


is shown. The assembly


200


consists of two sub-assemblies


201


and


202


with bars


210


and


220


, and


230


and


240


, respectively. As shown, the bars


210


and


220


of the first sub-assembly


201


extend in a first longitudinal direction and bar


210


is positioned above bar


220


. Bars


230


and


240


of the second sub-assembly


202


both extend in a second longitudinal direction at an angle with respect to the first longitudinal direction, and bar


230


is positioned above bar


240


.




Bar


210


is coupled to bar


230


at a joint


290


, and bar


220


is coupled to bar


240


at a joint


292


, thereby coupling the first sub-assembly


201


to the second subassembly


202


. The joints


290


and


291


may be fixed joints or hinged joints arranged to allow the first sub-assembly


201


to pivot with respect to the second sub-assembly


202


. In the example embodiment shown, the joints


290


and


291


are fixed joints and may be formed by bending a single longitudinal bar to form the bars


210


and


230


, and


220


and


240


. It may be advantageous to configure the scissor assembly


200


to include bars extending at two angles so that the scissor assembly


200


may be self-supporting or freestanding (i.e. may stand on its own).




Upper surfaces


211


and


231


of bars


210


and


230


are configured to provide a surface upon which the upper trim


800


may be coupled and a portion of a fireplace can rest. Flanges


212


,


222


,


232


, and


242


provide surfaces to which the front and side trims


900


and


1000


can be coupled.




The first sub-assembly


201


of the scissor assembly


200


also includes cross bars


250


and


260


positioned in a scissor arrangement. Likewise, the second subassembly


202


includes cross bars


270


and


280


positioned in the scissor arrangement. Each cross bar


250


,


260


,


270


, and


280


defines an aperture


255


,


265


,


275


, and


285


, respectively, at about a midpoint. In one embodiment, the cross bars


270


and


280


are coupled so that each bar


270


and


280


can pivot about its midpoint.




Referring now to

FIGS. 5-7

, bars


210


and


230


are shown in isolation. Each bar


210


and


230


defines an aperture


213


and


233


running in the first and second longitudinal directions, respectively. In the example embodiment shown, the apertures


213


and


233


are slots. In addition, each bar


210


and


230


defines an aperture


214


and


234


at ends


216


and


235


. Slots


223


and


243


and apertures


224


and


244


are similarly defined by bars


220


and


240


. The slots and apertures are sized to receive screws, as described below. Apertures


217


,


218


,


227


,


228


,


237


,


238


,


247


, and


248


may optionally be defined by the bars


210


,


220


,


230


, and


240


to facilitate attachment of the trim using, for example, screws or welding.




Referring now to

FIG. 8

, cross bar


250


is shown in isolation. In addition to the aperture


255


, cross bar


250


defines apertures


251


and


254


at ends


252


and


253


. Cross bars


260


,


270


, and


280


are configured in a like manner.




Referring now to

FIGS. 9-11

, the top, front, and side trims


800


,


900


, and


1000


are shown. In

FIG. 9

, the top trim


800


is shown with a surface


801


upon which a portion of a fireplace may be rested. The top trim


800


is also angled at corners


805


and


806


to match the first and second longitudinal directions in which the first and second sub-assemblies


201


and


202


extend. In

FIG. 10

, the front trim


900


is shown with a front surface


901


and angled portions


902


and


903


angled to extend in the first longitudinal direction in which the first sub-assembly


201


extends. In

FIG. 11

, one of the two side trims


1000


is shown with a front surface


1001


and an angled portion


1002


angled to extend in the first longitudinal direction in which the first sub-assembly


201


extends. The trims


800


,


900


, and


1000


are all configurable in size to hide the scissor assemblies


200


when the adjustable support is fully assembled, as is shown, for example, in

FIGS. 12 and 13

.




II. Support Structure Assembly




The adjustable support structure


100


can be assembled as follows. Each scissor assembly


200


can be assembled by first determining the desired height for the adjustable support structure


100


. The height of the adjustable support structure


100


can be adjusted by moving the apertures


251


,


261


,


271


, and


281


formed in the cross bars


250


,


260


,


270


, and


280


to a desired position along the slots


213


,


223


,


233


, and


243


formed in the bars


210


,


220


,


230


, and


240


. The closer the apertures


251


,


261


,


271


, and


281


are moved towards a midpoint of each bar


210


,


220


,


230


, and


240


, the greater the distance is created between bars


210


and


220


, and


230


and


240


, respectively, and the higher the bars


210


and


230


of the adjustable scissor assembly


200


are moved.




When the desired height is reached, the cross bars are coupled to the bars using, for example, screws. For example, for the first sub-assembly


201


, screws may be placed through apertures


254


and


214


, and


251


and slot


223


, to couple the cross bar


250


to the bars


210


and


220


. The head of each screw is typically larger than the width of the apertures and slots. In addition, screws may be placed through apertures


264


and


224


, and


261


and slot


213


, to couple the cross bar


260


to the bars


210


and


220


. In addition, a screw may be placed through apertures


255


and


265


to coupled cross bars


250


and


260


to one another at about the midpoint. The second sub-assembly


202


is assembled in a similar manner.




If the desired height for the scissor assemblies


200


has not been attained, the screws may be removed and the height of the scissor assembly


200


readjusted.




Once the scissor assemblies


200


have been assembled, the top, front, and side trims


800


,


900


, and


1000


can be added, as is shown in the exploded view of FIG.


1


and the fully-assembled views of

FIGS. 12 and 13

. The front and side trims


900


and


1000


may need to be sized depending on the height of the scissor assemblies


200


. For example, the front and side trims


900


and


1000


may be cut in the first and second longitudinal directions, as needed, to size a height


905


and


1005


of the front and side trims


900


and


1000


so that they fit onto the scissor assemblies


200


. Alternatively, front and side trims of different heights may be included, thereby eliminating the need for cutting.




Once the trim has been sized, each side trim


1000


can be coupled to surfaces


232


and


242


of the scissor assemblies


200


using, for example, additional screws. The front trim


900


can also be coupled to surfaces


212


and


222


of the scissor assemblies


200


. The top trim


800


can be coupled to surfaces


211


and


231


of the scissor assemblies


200


. In this configuration, the trims


800


,


900


, and


1000


can conceal the scissor assemblies


200


from view.




Referring now to

FIGS. 12 and 13

, the fully-assembled adjustable support structure


100


is shown partially supporting an example fireplace


1100


. As shown, a portion


1105


of the fireplace


1100


extends beyond a wall


1130


within which the fireplace


1100


is disposed. The fireplace


1100


may be positioned to extend beyond the wall


1130


in this manner because, for example, the fireplace


1100


may be larger than the enclosure defined by the wall


1130


of the structure within which the fireplace


1100


is being installed. Alternatively, it may be necessary to raise the fireplace


1100


to a desired level.




A lower portion


1110


of the fireplace


1100


is supported by the adjustable support structure


100


. Optionally, the adjustable support structure


100


may be connected to the fireplace


100


with screws or other attachment means following positioning under the fireplace


100


.




As described above, the adjustable support structure


100


can be adjusted, as desired, to support the lower portion


1110


of the fireplace


1100


at a variety of desired heights. The adjustable support structure


100


may be adjusted to the desired height prior to placement below the fireplace


1100


. Alternatively, the adjustable support structure


100


can be placed below the fireplace


1100


and then adjusted to the desired height.




The various components of the adjustable support structure


100


may be made of a variety of materials. In one example embodiment, the scissor assemblies


200


are made of a metal, for example, steel, of sufficient strength to hold a portion of a fireplace. In the example embodiment, the trim


800


,


900


, and


1000


is made of a sheet metal with surfaces


801


,


901


, and


1001


having a polished finish of a desired color such as, for example, gold, silver, or bronze. Alternatively, the surfaces may be the same color as the rest of the support structure or may be painted or otherwise colored to any desired color.




III. Alternative Embodiments




Many changes can be made to the example adjustable support structure


100


described above without departing from the spirit of the invention. For example, in

FIG. 14

, another example embodiment of a scissor assembly


200


′ is shown. The scissor assembly


200


′ includes only a first sub-assembly


201


′, rather than two subassemblies


201


and


202


as disclosed above. This sub-assembly


201


′ may be sized to extend across a substantially portion of the width of a front of a fireplace to support the fireplace. Alternatively, two sub-assemblies


200


′ may be used, positioned, for example, under opposing corners of the fireplace. Other configurations are also possible, such as, for example, three separate scissor assemblies including two angled assemblies under opposing corners of the fireplace and a straight scissor assembly under the front of the fireplace.




In another example of an alternative embodiment, the slots defined in the bars may be modified. Bars


210


′ and


230


′, shown in

FIG. 15

, each define a plurality of apertures


213


′ and


233


′ instead of a single slot. The apertures


213


′ and


233


′ function in a manner similar to the slots described above, allowing ends of the cross bars to be coupled to any of the apertures


213


′ and


233


′ to increase or decrease the height of the adjustable support structure.




In another embodiment (not shown), the slots may be formed with indentations of a greater diameter spaced along the slot. Ends of each cross bar may include an elongated pin that slides within the slot until an indentation at the desired height is reached. The pin could then be seated in the indentation, thereby locking the scissor assembly at a desired height.




In another possible alternative embodiment (not shown), each bar may be formed as two pieces that slidingly engage each other, and each cross bar may be mounted at opposite ends of each piece of the bar. To adjust the height, the two pieces of the bar may be slide to increase or decrease the overlap of the two pieces, thereby decreasing or increasing, respectively, the height of the scissor assembly. When a desired height is reached, the two pieces of each bar can be coupled to one another to lock them in place.




Other structures are also possible. For example, instead of each of the bars being formed as two pieces, each cross bar could be two pieces that slidingly engage each other. Each piece of each cross bar could be coupled at one end to the end of each respective bar, and each cross bar could extend vertically rather than crossing the opposite cross bar. The two pieces of each cross bar could be slid together or apart, thereby raising or lowering the upper bar, and affixed to one another at the desired height.




Other changes can also be made. For example, instead of using screws to couple the bars to the cross bars, other coupling devices may be used. For example, nuts and bolts, welding, or expanding gussets may be used in place of the screws to couple components of the structure support.




The configuration of the trim


800


,


900


, and


1000


may also be changed. For example, the front and side trims


900


and


1000


may be formed as a single, integral piece. In addition, the top trim


800


may be removed, if desired, if the fireplace


1100


covers the entire upper surface of the adjustable support structure


100


. The shape of the trim may also be modified. For example, the top trim


800


can be formed in a square or rectangle shape.




The present invention should not be considered limited to the particular examples or materials described above, but rather should be understood to cover all aspect of the invention as fairly set out in the attached claims. Various modifications, equivalent processes, as well as numerous structures to which the present invention may be applicable will be readily apparent to those of skill in the art to which the present invention is directed upon review of the instant specification.
