1. Field of the Invention
The present invention pertains to the art of fireplaces and, more particularly, to manufactured stone veneer assemblies for surrounding fireplace openings.
2. Discussion of the Prior Art
Interior fireplaces are often located in houses or other buildings such as hotels, restaurants, etc. to provide heat and also to add to the aesthetic appeal. Usually the fireplace is located in a wall of the house and has a fireplace opening so that the occupants of the home may tend to a fire in the fireplace and the fireplace can radiate heat into the house. The brick, stone, other masonry or wood detail surrounding a fireplace opening is known in the art as a decorative fireplace surround. Fireplace surrounds are commonly used to enhance the look and feel of a fireplace and also function to cover otherwise unsightly features of the fireplace, such as fireplace vents or the unfinished interface between the fireplace and the wall structure. Most commonly, surrounds are masonry structures prepared brick-by-brick or stone-by-stone by highly skilled and highly paid workers. Traditional brick or stone surrounds, for example, are composed of numerous individual bricks separated from each other by grout or mortar recessed between the bricks. The bricks are of uniform shape, but one row of bricks is offset from adjacent rows so that the grouted vertical spaces between bricks do not line up from row to row. While such a structure is quite durable, it is also quite expensive to construct.
Such surrounds may also include a mantel shelf that extends horizontally above the fireplace, and two legs that extend vertically along opposing sides of the fireplace. The mantel shelf and legs are often secured together as a single assembled piece that is mounted to the wall structure surrounding the fireplace. In other applications, the mantel shelf and leg members may be individually mounted to the wall structure surrounding the fireplace. It is sometimes also desirable to provide additional shelving and/or bookcase structure around the fireplace opening for supporting and displaying, for example, photographs, books and the like.
There have been attempts to provide fireplace surround assemblies that have the appearance of real brickwork but are made from artificial materials. Generally, such artificial surround assemblies have been molded from cement compounds that are formed to simulate the texture of actual brick and then colored with dye or paint to imitate the appearance of brick. For purposes of installation, such molded surrounds are usually cast as two units, i.e., a vertical legs and lintel unit and a horizontal hearth unit, which are positioned around a fireplace opening.
Unfortunately, affixing mantel shelves, legs or other surround components to the support wall can be difficult and time consuming. One known method includes applying an adhesive between the support wall and the surround component. A metal lath is placed on the wall and secured, then an adhesive, such as Portland cement (mortar), is spread on the lath and the fireplace surround component. The surround component is then placed against the lath. When the cement dries, the surround components are securely held in place. However, using a metal lath requires cutting, is expensive and sometimes difficult to install. Also, during construction of a building, hammering and other activities regarding the construction of a building may be taking place. Often the mantel shelf and legs may be displaced by other construction activities before the adhesive has dried. As a result, the mantel shelf, legs and other components may be positioned at an odd angle when the adhesive dries, giving an undesirable look and usually requiring an expensive fix.
Another proposed solution includes attaching a number of individual hooks to the support wall at the locations of wall studs. The method also includes attaching a number of hooks on the back of the mantel shelf or other surround components that engage the hooks on the wall. Once each of the hooks is properly positioned and affixed to the wall, the hooks on the mantel shelf are aligned with the hooks on the wall and the mantel shelf is hung on the wall. This method suffers in that it can be cumbersome and time consuming to properly position the hooks on the wall and the mantel shelf.
Based on the above there is a need in the art for a fireplace surround that is formed of inexpensive yet aesthetically appealing components that may be customized to different sized fireplaces and is easily installed by unskilled workers in a work environment subject to vibration caused by other construction activities.
The present invention is directed to a modular fireplace surround assembly adapted to be mounted to a support wall around a fireplace. The modular fireplace surround is formed from a plurality of surround components selected from first and second sets of components. In the first set of components, each component has a foam core and a manufactured stone veneer shell. These light weight components include non-noncombustible materials and are located at least eight (8) inches (at least approximately 20 cm) from the fireplace opening. In the second set of components, each component is formed of entirely noncombustible materials, and these components are formed from a manufactured stone veneer, such as lightweight concrete or glass reinforced concrete.
The fireplace surround is modular and, prior to installation, is customized by a consumer who may pick and choose components considered to be desirable by the consumer. Each of the components may be mounted to the support wall in various layouts. A fireplace surround according to a preferred embodiment of the invention may have one or more of the several components discussed below.
A mantel shelf is one of the more common surround components. The mantel shelf may be mounted in two preferred ways. In a first preferred embodiment, a metal track is mounted in the wall above the fireplace opening and brackets are mounted to the back of the mantel shelf. The mantel shelf is formed with a foam core and an outer shell. The foam core makes the mantel shelf relatively light and thus a workman can easily lift the mantel shelf and engage the brackets on the mantel shelf with the track on the wall. Additionally, the workman can put an adhesive, such as Thinset mortar or latex adhesive, on the back of the mantel shelf if a more secure connection is desired. The brackets will permanently hold the mantel shelf in place until the adhesive sets. In an alternative embodiment, the mantel shelf has a lower hollow main body with a reinforced back member adapted to receive fasteners that pass through the back member into the support wall. Such a connection is sufficient to permanently hold the mantel shelf in place, but adhesive may be used if desired. A top component is installed over the open upper portion of the main body and creates a finished surface that conceals the fasteners.
Some of the surround components are provided with a groove, located in a top surface, adapted to receive fasteners that pass through the component into the support wall and, when installed, the grooves are covered by a second component. Corbels, lintels and legs are examples of surround components that fall into this category. As discussed, each of these components is formed with an inner foam core and an outer shell formed of manufactured stone veneer however, the shell may be hollow. Surround components located near the fireplace opening are formed of solid manufactured stone veneer, such as glass reinforced concrete. Hearthstones, plinth stones, corbels, lintels and front facing blocks are examples of components that fall into this category. Finally, a front facing is constituted by a plurality of modular, interchangeable stone components arranged about the top and sides of the fireplace opening. These components may be placed anywhere in the surround but are shown framed by a mantel shelf on top, legs on the sides, and a hearth below. It should be understood that the components could be brick, marble or granite tiles, slabs, or stone pieces as well.
When a workman installs the fireplace surround, the following method is typically used. A consumer selects a first array of desired components from the first set of components each having a foam core and a manufactured stone veneer shell designed to be located at least eight (8) inches (20 cm) from the fireplace opening. A consumer then selects a second array of desired components from the second set of components formed of entirely noncombustible materials including manufactured stone veneer or other noncombustible facing materials such as natural stone, brick, granite, or limestone tile etc. The first array of desired components are temporarily mounted in the fireplace surround. For example, a pair of leg members is mounted on the wall by passing fasteners through a groove in each of the leg members and into the wall. The grooves and fasteners are then covered with another of the plurality of components, such as a pair of corbels or a mantel shelf. Likewise, a pair of corbels is mounted on the wall by passing fasteners through a groove in each of the corbels into the wall, with the groove and fastener being covered by the mantel shelf. A lintel is mounted on the wall above the opening by passing fasteners through a groove in the lintel into the wall and covering the groove and fastener with the mantel shelf. The mantel shelf is generally the last of the components to install. A hearth is mounted on the floor below the opening when the surround is placed around a wood fireplace. A pair of adjustable plinth stones is placed on the hearth. A front facing, including a plurality of modular, interchangeable components each formed of an artificial stone veneer, is placed between the mantel shelf and the hearth in a desired pattern and fixed in place with an adhesive. Additionally, selected components can be installed on the support wall.
With this arrangement, a fireplace surround can be quickly and inexpensively installed on site. Additional objects, features and advantages of the present invention will become more readily apparent from the following detailed description of preferred embodiments when taken in conjunction with the drawings wherein like reference numerals refer to corresponding parts in the several views.

As can be seen from the above discussion, the surround assembly 40 can use two types of components 42. A first set of components has a foam core and a GFRC manufactured stone veneer shell. The foam core makes these components light, but since they are not made entirely of noncombustible materials they are located at least 8 inches (20 cm) from the fireplace opening. A second set of components is formed of entirely noncombustible materials and these components are formed from a manufactured stone veneer, such as glass reinforced concrete or lightweight concrete. In one embodiment, the method of establishing the surround assembly 40 includes having first array of desired components selected from a first set of components having a foam core and a manufactured stone veneer shell designed to be located at least 8 inches (20 cm) from the fireplace opening. For example, legs and lintels and mantel/shelves can be in the first array An array set of desired components is also selected from a second set of components formed of entirely noncombustible materials including manufactured stone veneer. For example, hearthstone or plinth stones and cove moldings can be in the second array.
The desired components from the first set of components are temporarily mounted around the fireplace opening. For example, in accordance with the embodiment of
Although described with reference to preferred embodiment of the invention, it should be readily understood that various changes and/or modifications can be made to the invention without departing from the spirit thereof. For instance, a fireplace surround assembly may be made entirely with front facing of interchangeable blocks and not include a mantel shelf or a hearth extension. In fact, given that a consumer can readily pick and choose desired components from the first and second arrays, a wide range of readily producible fireplace surround assemblies can be established. In addition, it should be realized that the order of assembly of the components as set forth herein could readily be altered without affecting the overall, final fireplace surround system construction. Components described as having a foam core can also be made with fire resistant hollow core GFRC. In general, the invention is only intended to be limited by the scope of the following claims.
