Description




BACKGROUND OF THE INVENTION




This invention relates to log burning devices, and more particularly to racks used for firelogs to produce an effect similar to that of a wood fire.




Use of firelogs in place of wood logs is growing due to the ease in which firelogs are acquired, stored, and lighted. Firelogs were originally created to recycle sawdust; they burn with significantly fewer pollutants and emissions than natural firewood and are also made of recycled materials. Firelogs are also very popular because they produce less ash, carbon monoxide, and creosote than firewood, resulting in less chimney blockage. But firelogs do not create the same effect as that of a real wood fire. The difference between firewood and firelogs is noticeable.




Many attempts have been made to create burning devices that accommodate firelogs and simulate the appearance of a wood fire. U.S. Pat. No. 5,435,295 to Gerrard, U.S. Pat. No. 5,423,310 to Hudson, and U.S. Pat. No. 5,069,200 to Thow disclose burning devices exemplary of the state of the art. Significantly, all of these burning devices are poorly designed for replenishing a burning fire. The process for replenishing logs in these burning devices involves manually removing the hot artificial logs, adding a fresh firelog, and replacing the hot artificial logs. This complicated method requires a user to work extensively with fire and hot artificial logs, using cumbersome fire tools or even his own hands. This method is laborious and increases the risk of burns.




The burning device disclosed in the Gerrard patent includes a two-tiered rack: the lower tier is for supporting compressed paper logs, and the upper tier is for supporting artificial vacuum-formed ceramic logs. The lighted firelogs burn up through the artificial logs to give the ambience and appearance of a pile of real logs burning. As set forth above, to load firelogs onto a lighted fire, the user must remove the ceramic logs and eventually replace them.




The devices disclosed in the Hudson and Thow patents are for use with gas-fueled fireplaces. Both devices use artificial logs that are positioned individually to achieve the glowing appearance of a wood fire. This is poorly adaptable to firelogs because of the difficulty in replacing the artificial logs after a firelog has been lighted.




SUMMARY OF THE INVENTION




The log burning device of the present invention is easy to use and simulates a natural wood fire in both appearance and generation of heat. Because known burning devices are difficult to use, an easy-to-use burning device that can simulate a natural wood fire and generate a similar amount of heat is still needed. The present invention solves the problems of the aforementioned burning devices.




One preferred embodiment of the present invention is directed to a log burning device that includes a standing grate, which supports at least one log, and a cover attached by at least one hinge to the standing grate. In one preferred embodiment, the cover has the shape of at least one simulated log. When the log burning device contains a lighted firelog, it has the appearance of a burning wood fire.




Another preferred embodiment of the present invention is directed to a method for burning logs, which includes rotating a cover to an open position. A log is then loaded onto the fireplace standing grate and lighted. The cover is then rotated to a closed position.




The foregoing and other objectives, features, and advantages of the invention will be more readily understood upon consideration of the following detailed description of the invention, taken in conjunction with the accompanying drawings.

create cutouts. The hole


58


, cutouts, and other openings allow for escape of smoke and flames and for sufficient airflow. It should be noted, however, that the hinged log cover


40


shown and described is meant to be exemplary. For example, more or fewer simulated logs


42


,


44


,


46


,


48


,


50


can be used depending on the size of the burning device and the effect desired. Further, the simulated logs


42


,


44


,


46


,


48


,


50


can be created in a stacked position to resemble a log pile. The simulated logs


42


,


44


,


46


,


48


,


50


can also be placed so that each would run the length of the cover. The cover can also be made in other decorative and novelty shapes.




Preferably, the hinged log cover


40


is placed substantially over the standing grate


20


and attached by hinge thereto. The right and left sides of the hinged log cover


40


(

FIGS. 1 and 2

) each have a downward-reaching arm


60


,


62


with a hole (not shown) fitted for hinges


36


,


38


. In the shown embodiment, upward-reaching arm


32


is aligned with downward-reaching arm


60


, and upward-reaching arm


34


is aligned with downward-reaching arm


62


. Hinge


36


is inserted into the respective arm holes to connect upward-reaching arm


32


and downward-reaching arm


60


. A hinge


38


is inserted into the respective arm holes to connect arms


34


and


62


. Once the arms


32


,


34


,


60


,


62


are connected, the hinged log cover


40


is connected to the standing grate


20


and is easily rotated to an open position (

FIGS. 2 and 4

) and to a closed position (FIGS.


1


and


3


). Pins (not shown) can be attached to the hinges to secure the hinged log cover


40


to the standing grate


20


. It should be noted that the shown hinges are meant to be exemplary and that known hinges, including but not limited to leaf springs, butt hinges, loose joint hinges, spring hinges, gas springs, or support hinges, may be substituted for the shown hinges. Also, the cover


40


could be hinged only on either the left or the right side so as to lift open to the right or left rather than from front to back. An alternative preferred embodiment would include a sliding cover.




Both the standing grate


20


and the hinged log cover


40


may be constructed from cast iron, metal, or other material able to withstand the heat of a log fire.




When rotated open, the hinged log cover


40


has an open position sufficient to allow at least one log to be inserted. In the preferred embodiment, the cover


40


can be rotated approximately 30° to 120° from the standing grate


20


. In the closed position, the cover


40


is substantially parallel and adjacent to the standing grate


20


.




An opening tool


64


(FIG.


2


), similar to a fire poker, may be used to move the cover between the open position (

FIGS. 2 and 4

) and closed position (FIGS.


1


and


3


). In the shown preferred embodiment, the opening tool


64


is forked and made of cast iron or other material able to withstand the heat of a fire. The exemplary opening tool


64


has a looped handle


66


, making it easy to grasp. In the preferred embodiment, appendage


54


on the hinged log cover


40


provides a catch for the opening tool


64


. It should be noted that the shown opening tool


64


is meant to be exemplary, and that known devices, including but not limited to fire pokers or fire tongs, could be substituted.




In use, the present invention is placed in a fireplace near a rear wall, allowing the invention to be opened and closed. The hinged log cover


40


is rotated to an open position (FIGS.


2


and


4


), preferably using the opening tool


64


(FIG.


2


). Next, at least one firelog


22


may be added to the standing grate


20


(FIGS.


3


and


4


). Once the firelog


22


is lighted and has attained proper ignition, the opening tool


64


is used to rotate the hinged log cover


24


to a closed position (FIGS.


1


and


3


). It is also possible to close the hinged log cover and then light the firelog. Flames and smoke escape through the openings of the hinged log cover


40


, created by hole


58


and use of appendages


52


,


54


,


56


, creating the appearance of a burning wood fire. To replenish a burning fire, the hinged log cover


40


is rotated to an open position (FIGS.


2


and


4


), using the opening tool


64


. At least one new firelog


22


is then inserted (FIGS.


3


and


4


). The hinged log cover


40


is then rotated to a closed position (

FIGS. 1 and 3

) using the opening tool


64


. This method of using the burning device of the present invention reduces the risk of burns because the user uses the opening tool


64


to rotate the hinged log cover


40


. Further, because the shown hinged log cover


40


is a single unit, the user does not have to replace individual artificial logs, and thus the risk of burns is again reduced.




It should be noted that alternate preferred embodiments simulate, for example, the appearance of wood fires, burning coals, gas fires, debris fires, and other burnings.
