RELATED APPLICATIONS

This application relates to and claims the benefit of the provisional application 60/452,478, filed Mar. 5, 2003, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention is directed to masonry, and in particular to factory built masonry.
2. Description of the Related Art
Masonry structures have are well known in the art and have existed for many years. Many traditionally site built masonry structures (e.g., fireplaces, countertops, brick walls, and the like) may have to be constructed by a mason and thus can be expensive. Traditional site built masonry structures can also require significant installation time. For example, site built masonry fireplaces commonly found in residential structures and can be expensive and require substantial installation time.
Over the years, factory built fireplaces have grown in popularity due to the increased cost of site constructed masonry structures. Additionally, building code restrictions in some localities limit or altogether prohibit the use of masonry chimneys, making the use of factory built fireplaces desirable in these localities. Moreover, factory built fireplaces are capable of being installed in multi-level buildings, where construction of traditional masonry units is not feasible.
Even where the construction of masonry fireplaces is feasible, construction usually requires a significant amount of time and costs, significantly more than a factory-built fireplace. Additionally, installation of tradition masonry fireplaces generally requires the services of a licensed mason or other construction professional, adding to the cost of construction.
Throughout the development of the factory-built fireplace industry, designers have sought to design fireplaces to resemble traditional masonry built fireplaces. For example, recent designs of factory-built fireplaces have incorporated refractory panels to better resemble a masonry fireplace. However, such refractory panels, and other similar designs, have been incapable of achieving the desired masonry look. In another example, bricks have been added to the firebox area of a fireplace in an attempt to create a masonry look. However, such construction design has proved structurally unstable, often falling and breaking, and thus unable to provide adequate retention of bricks. Additionally, such designs have provided poor alignment of bricks and have not been capable of providing multiple brick pattern arrangements.
The desire for factory-built fireplaces that resemble masonry fireplaces is particularly strong among owners and builders of high-end homes, who prefer the traditional look of masonry fireplaces. However, as noted above, some localities restrict or prohibit the use of masonry fireplaces due to, for example, the risk of seismic activity in the locality. Thus, there is a need for factory built masonry structures that resemble site built masonry.

SUMMARY OF THE INVENTION

In accordance with one embodiment of the invention disclosed herein, panels can comprise a backing and a plurality of walls attached to the backing. The walls can have holding members configured to hold a body, such as a brick or tile. The holding members of the walls cooperate to receive and hold firebricks. The holding members can be tabs that extend from the walls of the panels. The walls having the holding members can be generally perpendicular to the panels. The panels can be prefabricated panels used to build traditionally site built masonry structures. The site built masonry structures can be, e.g., fireplaces, countertops, brick walls, or hearths.
In accordance with one embodiment of the invention disclosed herein, a factory-built fireplace is designed to look like a traditional masonry fireplace. The fireplace comprises a firebox having an inner cavity and a chimney system. The cavity preferably comprises a frame comprising rails or panels that define the periphery of the cavity. The frame defines side areas, a rear area, a base area and a top opening in the firebox, wherein the opening is preferably connected to the chimney system. In addition, the fireplace includes masonry panels configured to be installed on the side areas, rear area and base area of the cavity frame.
The masonry panels are preferably made of a metallic material, such as steel. However, the panels can be made of any material providing the necessary structural, thermal, and other characteristics required in fireplace construction. Also, the panels are preferably sized to cover substantially the entire side, rear and base areas of the cavity frame. Additionally, the panels preferably have a thickness capable of providing adequate structural support to the masonry material installed thereon.
The panel disposed over the base of the firebox cavity optionally defines an opening therethrough. The opening is preferably disposed near a front edge of the base of the firebox, wherein the front edge of the base is near the front end of the firebox. Additionally, a removable cover can optionally be disposed over the opening. The opening is preferably sized to receive a removable ash dump, which is capable of receiving ashes produced during the burning of logs or other material in the fireplace. The ash dump is preferably configured to be easily removed from the opening and to be easily emptied. The cover and the ash dump are preferably configured to be removed and replaced without the use of any tools.
The fireplace also includes a plurality of firebrick housings configured to be installed on the masonry panels. For example, the housings can be bolted, screwed, riveted, or welded to the panels. The firebrick housings can optionally be attached to the panels so that they are arranged in a running bond, a herringbone pattern, or other decorative pattern. The housings are preferably disposed such that a gap is between adjacent housings. Optionally, the housings can be disposed so that there is no gap between adjacent housings.
The firebrick housings are preferably sized to receive a firebrick thereon. However, the housings can optionally be configured to receive any material suitable for use in a fireplace or other high-temperature environment. Additionally, the housings preferably comprise at least one holding member configured to adequately hold a firebrick in the housing. In one embodiment, for example, the holding member is a structure that extends from the wall of the housing. The extending structure is advantageously configured to engage with at least one groove in the firebrick. In another example, the holding member is a plurality of protuberances extending outward from the surface of the housing, configured to receive mortar around the protuberances, and to adhere to a firebrick disposed thereon. In still another example, the housing can be configured to receive and hold a firebrick without the use of mortar or other adhering material. Additionally, mortar is preferably introduced into the gaps disposed between the housings to achieve the look of a traditional masonry fireplace.
The firebricks of the masonry panels are configured to be coupled to the panels. Preferably, the panels have firebrick housings configured to receive and hold firebricks. A portion of the firebrick is preferably of similar shape as a portion of the housing. For example, both the firebrick and housing can be generally rectangular. In one embodiment, the firebrick comprises the pair of sides, each side having a channel or groove that is configured to receive a portion of the holding member. The channel or groove can have a generally U-shaped or similar cross-section. The groove can extend along a portion of the firebrick. In another embodiment, the groove extends from one side of the firebrick to an opposing side of the firebrick. The masonry panel can comprise bricks having grooves and some bricks without grooves.
In accordance with another embodiment, factory-built masonry structures are able to be constructed at significantly less cost than traditional masonry structures. The masonry panels are preferably constructed such that the costly layout of the brick pattern is eliminated. Additionally, individual brick housings are preferably incorporated into the panel to advantageously allow fast and accurate construction. For example, the panels can be constructed having the firebrick housings pre-arranged in a specific pattern, such as running bond or herringbone. Moreover, the firebricks supplied with the fireplace are preferably pre-cut and identified as corresponding to a particular housing, advantageously reducing the time, and thus the cost, of construction. For example, the fireplace can be constructed by an individual who may not normally have expert masonry skills, again reducing the construction costs. For example, the fireplace can be constructed by a certified fireplace installer or a homeowner Accordingly, a factory-built masonry fireplace can be constructed to resemble a traditional masonry fireplace at less than 20% of the cost and significant savings in installation time.
In accordance with another embodiment, the necessary materials for constructing a factory-built masonry fireplace are provided in a kit. The kit preferably comprises a firebox defining a cavity with a frame, the frame having side areas, a rear area, a base area, and a top opening. The kit also comprises a chimney system, wherein the chimney system connects to the top opening of the cavity frame. The kit also comprises a plurality of masonry panels preferably configured to be removably attached to the side areas, rear area and base area of the cavity frame. A plurality of firebrick housings is preferably attached to the masonry panels. Additionally, a plurality of preferably pre-cut firebricks is provided, wherein the firebricks preferably correspond to the plurality of housings. The kit also comprises an amount of high-temperature cement.
The kit enables the user to easily install the plurality of firebrick housings onto the masonry panels and arrange the housings in a desired pattern, such as running bond or herringbone. Alternatively, the housings can be pre-installed and arranged at a factory prior to delivery of the kit to the user. The user then installs the masonry panels on the side areas, rear area, and base area of the cavity frame. Optionally, the masonry panels and the cavity frame are assembled and pre-installed at the factory. The user can mix the high-temperature cement to prepare mortar material. The user can place the bricks into the housings of the panel, where the firebrick preferably corresponds to the housing. The user can repeat this process with the remaining firebrick housings. Once the user has installed the plurality of firebricks in the plurality of housings, the user can apply mortar material into any gaps between any adjacent firebricks to grout the firebrick assembly. The user can then allow the masonry fireplace cure for a desired amount of time before use. Once the masonry fireplace is properly cured, the user can optionally install a facade around the fireplace, as desired. The facade can be formed of masonry panels having housing configured to receive and hold firebricks. Firebricks can be coupled to the masonry panels to achieve a site built masonry appearance.
Other objects, advantages, and features of embodiments of the present invention will become readily apparent to those skilled in this art from the ensuing detailed description of preferred embodiments thereof.

FIG. 3A illustrates a panel 60 b in the form of a masonry panel for the base of the fireplace 100. The panel 60 b is configured to receive and hold a plurality of firebricks. According to the illustrated embodiment, a plurality of templates or firebrick housings 70 is preferably removably attached to the panel 60 b. It should be understood that the firebrick housings 70 can be similarly arranged on the panels 40 b, 50 b disposed on the rear area 40 a and side areas 50 a of the firebox cavity 30.
In the illustrated embodiment, the plurality of housings 70 are aligned in a running bond pattern. However, the housings 70 may be arranged in other patterns, such as a herringbone pattern. Additionally, according to the illustrated embodiment, the housings 70 are preferably aligned in a row with no gap between the ends of the housings 70. Also, the housings 70 are disposed such that there is a gap between the rows of housings 70. Optionally, the housings 70 can be arranged so that there is a gap between the housings 70 forming a row. Also, the housings 70 can optionally be arranged so there is no gap between the rows of housings 70.
The housings 70 are preferably attached to the masonry panels 40 b, 50 b, 60 b with readily available connectors and fasteners (not shown), such as bolts, screws, rivets or welds.
FIG. 3B illustrates a panel 60 b for the base of the fireplace 100. The panel 60 b is configured to receive and hold at least one brick. In the illustrated embodiment, the plurality of firebrick housings 70 are attached to the panel 60 b and are aligned in a herringbone pattern. There can be gaps 102 between the sides or the ends of the housings 70. Optionally, in some embodiments, there may be no gaps between the housings 70. Although not illustrated, the panel 60 b and the housings 70 can be integrally formed.
At the periphery of the panel 60 b are edges 104, each edge having a plurality of openings or holes 106 that are used to couple the masonry panel 60 b to the fireplace 100. According to the illustrated embodiment, the edges 104 comprise a flat body having openings 106 configured to receive a screw, fastener, or other suitable device for attaching the panel 60 b to the fireplace 100. Thus, to install the masonry panel 60 b, the panel 60 b can be placed in the desired location in the fireplace 100 and fasteners can be passed through the openings 106 to secure the panel 60 b to the fireplace.
The housings 70 are preferably attached to the masonry panel 60 b by passing fasteners through at least one opening or hole 108 in each of the housings 70. In the illustrated embodiment, the housings 70 are attached to a backing of the panel 60 b and the backing of the panel 60 b can be sheet metal or other suitable structure for holding the housings 70 which in turn hold firebricks.

The firebrick 120 is preferably configured to engage with at least one of the holding members 78 a to ensure that the firebrick 120 remains in the panel 60 b. In one embodiment, the firebrick 120 has at least one groove 122 along a side 124 of the firebrick 120. The groove 122 is sized for receiving the end portion 125 of the holding member 78 a to limit the movement of the firebrick 120. Preferably, at least a portion of the edge 79 is disposed within the groove 122. Optionally, the firebrick 120 can comprise a pair of sides 124 and a plurality of grooves 122. The firebrick 120 can have the groove 122 along one side 124 and another groove 122 along another side 124. In the illustrated embodiment, for example, the firebrick 120 is generally rectangular and has a pair of sides 124 that are generally parallel and rectangular, each side 124 having the groove 122.
The holding member 78 a in the form of a flange or tab can extend from the wall 110 and engage with the firebrick 120. The holding member 78 a has one side connected to the wall 110 and another side having the end 125. As shown in FIGS. 3B and 5, an opening 126 is defined by the holding member 78 a and the wall 110. The holding member 78 a can have a generally curved cross-section, straight cross-section, or any other suitable shape to hold the firebrick in the housing 70. In the illustrated embodiment, the holding member 78 a has a cross-section that has a curved portion and straight end portion. The member 78 a can have a generally uniform thickness. Those skilled in the art recognize that the member 78 a can have a non-uniform thickness. The member 78 a, for example, can have a thickness that is reduced towards the end 125.
The holding member 78 a has the end 125 that is configured and sized to fit in a portion of the firebrick 120 to thereby hold the firebrick 120. In the illustrated embodiment, the end 125 of the holding member 78 a is preferably configured to fit within the groove 122 of the firebrick 120. However, the end 125 may be configured to fit within a hole or other structure in the firebrick 120 for holding the firebrick.
The grooves 122 and the holding members 78 a can be arranged so that the bottom of the firebrick 120 engages with the base 112. The base 112 can inhibit the movement of the firebrick 120. However, the grooves 122 and the holding members 78 a can be arranged so that the bottom of the firebrick 120 and the base 112 are spaced apart so that a cement mixture can be received in the gap between the firebrick 120 and the base 112. Further, the firebrick 120 and base 112 can be spaced apart so that at least one of the holding members 78 b, 78 c (described below) are disposed between the firebrick and the base.
FIG. 6A and FIG. 6B illustrate the firebrick housing. The housing 70 preferably has at least one sidewall 110 having a plurality of holding members 78 a, where at least one holding member 78 a is located on either side of the wall 110.
In the illustrated embodiment, the housing 70 comprises the pair of walls 110. A first holding member 78 a is disposed on one side of the wall 110 and a second holding member 78 a is disposed on the other side of the wall 110. The walls 110 are spaced apart and configured to receive the firebrick 120 within the cavity 114 and engage with at least one firebrick 120 a, which is exterior the housing 70. In other words, the wall 110 engages with the firebricks located on either side of the wall 110. As in the illustrated embodiment, each sidewall 110 has a pair of holding member 78 a, each holding member 78 a engages the groove of the firebrick. Although not illustrated, the wall 110 can have a plurality of holding members 78 a located on one side of the wall 110 and a plurality of holding member 78 a located on the other side of the wall 110.
Gaps 102 can be formed between adjacent firebricks 120 as shown in FIG. 6B. Cement mixture can be disposed in the gaps 102 to further ensure that the firebricks 120 remain in the masonry panel 60 b. Optionally, the cement mixture can be placed within voids between the firebricks 120, 120 a and the housing 70 to ensure that the firebricks remain securely attached to a masonry panel 60 b. Thus, the holding member 78 a in combination with a cement mixture ensure that the firebricks 120, 120 a remain securely coupled to the firebrick housings 70. The housing 70 can comprise a variety of different holding members. For example, the housing 70 can have at least two of the holding members that in combination hold the firebrick 120.
FIG. 7 illustrates a firebrick housing 70 that is generally similar to the housing 70 of FIG. 6. The firebrick housing 70 has a plurality of holding members 78 a extending into the cavity 114 configured to engage a firebrick. The housing 70 can have a lip or flange 113 at its upper and lower ends for engaging the ends of the firebrick. The flanges 113 can inhibit movement of the firebrick which is captured by the housing 70. Thus, the holding members 78 a and flanges 113 cooperate to ensure that the firebrick remains securely held in the housing 70. In the illustrated embodiment, the holding members 78 a prevent the firebrick from being moved away from the base 112 and the flange 113 prevents the firebrick from sliding along the longitudinal axis of the housing 70. Although not illustrated, there are other suitable structures that can prevent undesirable movement of the firebrick disposed within the housing 70.
With respect to FIG. 8, the holding members 78 a are located on each side of the firebrick, shown in phantom. In the illustrated embodiment, the holding member 78 a is in a form of flange or tab. The tab 78 a is generally straight and extends at an angle from the wall 110. The end 125 of the tab 78 a is preferably adapted to engage with grooves 122 to hold the firebrick. When the brick 120 is held by the housing 70, flexible walls 110 of the housing 70 can contact and tightly grip the sides 124 of the brick 120. Further, the bottom of the brick 120 preferably contact the upper surface of the base 112 to reduce movement of the brick 120 relative to the housing 70.
FIG. 9A and FIG. 9B illustrate a firebrick housing. The housing 70 preferably comprises at least one sidewall 72 and a base 74 defining a cavity 76. In one embodiment, the housing 70 has at least two sidewalls 72 extending from the base 74 and defining the cavity 76, which is generally rectangular in shape and is preferably configured to receive a firebrick. However, the housing 70 is not limited to having at least two sidewalls 72. In another embodiment, the housing 70 comprises a single sidewall 72. The sidewall 72 can be formed of metal or other suitable material for holding firebricks.
The cavity 76 is preferably configured to receive a pre-cut firebrick. However, the cavity 76 can optionally be configured to receive a brick that is not pre-cut. In another option, the cavity 76 can be configured to receive any material suitable for use in a fireplace or other high-temperature environment. In the illustrated embodiment, the base 74 of the housing 70 has a generally rectangular shape. However, the base 74 is not limited to a rectangular shape and can comprise other shapes configured to receive a firebrick of generally similar shape.
In the illustrated embodiment, a holding member 78 b is preferably disposed on the base 74 of the firebrick housing 70. The holding member 78 b can optionally be removably attached to the base 74 of the housing 70 using any number of connectors or fasteners, such as screws or rivets. In another option, the holding member 78 b can be welded to the base 74 of the housing 70.
The holding member 78 b is preferably configured to hold a firebrick in the housing 70 in combination with mortar material. In the illustrated embodiment, the holding member 78 b is a wire mesh. However, the holding member 78 b can comprise any structure capable of holding a firebrick on the housing 70. For example, the holding member can comprise a plurality of protuberances 78 c, as illustrated in FIGS. 10A and 10B. In another example, the at least one sidewall 72 can comprise the holding member.

Some of the housings can comprise a holding member to ensure that the firebricks remain properly secured in the masonry panel 60 b. The housing 70 can comprise a variety of different holding members, such as holding members 78 a, 78 b, 78 c. It is contemplated that those skilled in the art can determine the appropriate type and sized of housing and holding members for a desired pattern of firebricks, structural properties of the panel, and the like. A further advantage is provided where the housings 70 have holes or apertures so that the housings can be conveniently and quickly coupled to masonry panels 60 b either on site or in the factory.
FIG. 13 is perspective view of the firebrick 120 similar to the firebrick of FIG. 5. As discussed above, the firebrick 120 is configured to fit within the cavity 114 of the housing, such as housing 70. A portion of the firebrick 120 is preferably of similar shape as a portion of the housing 70.
In the illustrated embodiment, the firebrick 120 comprises the pair of sides 124, each side 124 having the channel or groove 122. The groove 122 is generally U-shaped. However, the groove 122 is not limited to a U-shape and can comprise other shapes configured to receive a portion of the holding member, such as holding member 78 a. In other embodiments for example, the groove 122 can be V-shaped.
The groove 122 can extend along a portion of the side 124 or along the entire length of the side 124. The groove 122 can have a longitudinal axis that is generally parallel to the upper surface 130 and the lower surface 132 of the firebrick 120. The groove 122, of course, can be at different locations on the brick 120 depending on the configuration of the housing that the brick is attached to. Further, many of the bricks 120 disposed in the masonry panel 60 b may not have any groove 122. In other words, the panel 60 b can comprise bricks 120 having grooves 122 and some bricks 120 without grooves.
The firebrick 120 can be coupled to the panel (e.g., the panel 60 b) by inserting the firebrick 120 into the cavity 114 of a housing (e.g., the housing 70) so that the holding member 78 a contacts and presses against the firebrick 120 as the firebrick passes through the cavity 114. The holding members 78 a are pushed away or towards the sidewalls 110 as the brick 120 is inserted into the cavity 114. When the firebrick 120 reaches the desired position, the ends 125 of the holding member 78 a move into the groove 122, preferably when the bottom of the firebrick is near the base 112, resulting in the firebrick 120 being held by the housing. Thus, the firebrick 120 can be quickly and conveniently installed or assembled by pushing the firebrick into the cavity 114 and against the base 112 and the members 78 a snap into the grooves 122 thereby securing the brick in the fireplace 100. Thus, firebrick can be held captive by the panel without the use or mortar or cement. The firebrick can be attached to the fireplace 100, as shown in FIG. 1A, without the use of cement.
Preferably, the firebrick 120 is held by the panel 60 b so that the firebrick 120 cannot be pulled off of the panel 60 b. Thus, the firebrick 120 can be permanently attached to the panel 60 b without the use of cement or mortar. Optionally, the firebricks can be coupled to the housings by sliding the ends 125 of the holding members 78 a into the ends of grooves 122 of the brick. The ends 125 can then be slide along the groove 122 until the brick reaches the desired position. A further advantage is provided where the firebricks can be pre-cut and identified as corresponding to a particular housing, advantageously reducing the time, and thus the cost, of construction. In one embodiment, the brick has indicia or markings that indicate a corresponding housing that is configured to receive that brick.
Cement or mortar can be used to achieve a traditional site built masonry appearance. For example, after bricks 120 are attached to the panel 60 b, cement can fill in the spaces between the bricks 120 resulting in a masonry panel that has a traditional masonry appearance. The cement can provide structural support to further ensure that the bricks 120 remain attached to the panels 60 b. Those skilled in the art recognize that there are various methods of attaching bricks 120 the panels and applying cement to achieve the desired appearance.
As illustrated in FIGS. 2B, 3A, and 15 by the dashed lines, a cover 180 is preferably removably disposed on the base masonry panel 60 b proximal to an edge 62 b, wherein upon installation of the panel 60 b in the fireplace 100, the edge 62 b is proximal to the front end 12 of the fireplace 100.

In the illustrated embodiment, the cover 180 can be manually removed exposing the opening 182 and the ash dump 184. Ash from the cavity 30 can be conveniently swept through the opening 182 so that the ash falls through the opening 186 and into the ash dump 184. Thus, ash produced from the burning of material can be removed from the cavity 30 and stored in the ash dump 184. The cover 180 can be replaced to cover the opening 182 for an attractive brick pattern defined by the panel 60 b and the cover 180. These steps can be repeated to remove ashes within the cavity 30 for an attractive, ash free, fireplace 100. In one embodiment, the material, such as wood logs, for burning can be located between the opening 182 and the masonry panel 40 b so that the cover 180 can be removed and ash can be dumped in the ash dump 184 while the wood logs conveniently remain in the cavity 30. The ash dump 184 can preferably be removed from the fireplace 100 and emptied while the wood logs remain in the cavity 30.
The ash within the ash dump 184 can be conveniently disposed of by removing the cover 180 and exposing the ash dump 184. The ash dump 184 can be pulled through the opening 182 and removed from the fireplace 100, preferably without employing tools. The ash dump 184 can be transported to a garbage container (e.g., a trash can) and the ash from the ash dump 184 can be transferred to the garbage container. The empty ash dump 184 can be replaced in the fireplace 100 by passing the ash dump 184 through the opening 182. The cover 180 can be placed over the opening 182 and the ash dump 184, thereby hiding the ash dump 184 underneath the cover 180 and the panel 60 b.
