This disclosure is generally related to grills, such as barbeque and related grilling devices.
Barbecue grills and the grilling of food is well known. As the grilling of food, such as meat and vegetables, becomes increasingly popular, many innovations have been developed related to grills and grilling devices.
Many types of grills, such as, for example, propane gas grills, include a cooking grate the provides a surface for resting foods above a heat source. As is commonly known, the grates typically take the form of spaced apart rods or bars within a frame. The frame is shaped to fit the dimensions of a corresponding grill, and this can be circular, oval, square, or rectangular in shape. The grate is typically made of metal such as steel or iron.
However, different types of grill grates have different types of shortcomings. For example, with some grill grates, the spaces between grill rods is such that small food items such as small pieces of meat and vegetables can easily fall between the grill rods.
Further, with some grill grate designs, the mass of the grill rod material is such that heat is not significantly retained after the heat source, such as a propane flame, is turned off. In such situations, a user tends to keep the heat source on for a longer period of time, which can lead to overcooking of the food items.
Still further, with some current grill grate designs, fat, juices and marinades that are released from meats quickly leave or drip off of the grill rods and do not contribute greatly to adding flavor to the food being cooked. On the other hand, with some other grill grate designs, fats and juices are retained at the cooking surface for a relatively long period of time, which can lead to burning, fires and unwanted smoking.
In addition, some grill grate designs incorporate square (in cross-section) shaped rods in which food pieces and particles can be retained and stuck, with the rod shape making it relatively difficult for a user to clean the grill and remove stuck food pieces from between the grill rods.
In contrast, other known grill grate designs use narrow round (in cross-section) rods which contribute, due to their shape, to food sticking to the grill rods. Further, grill grate designs with narrow rods can tend to warp over time due to repeated heating and cooling.
Thus, there is a need in the art for an improved grill grate design that addresses one or more of the above shortcomings of the related art/

In some embodiments, as discussed above, grill grate 100, when viewed from the top or bottom, forms a square or rectangular shape, to conform with the shape and structure of a grill for which the grill grate 100 is to be used. In other embodiments, grill grate 100 can be shaped and designed to fit the receiving areas of grills having other shapes, such as, for example, circular or oval-shaped grills. In other embodiments, grill grate 100 can form other shapes, as would be understood by those of skill in the art, when informed by the present disclosure.
In certain embodiments, the pentagonal shape and volume of grill bars 200, as well as the relatively close distance between adjacent grill bars 200 can provide for a relatively long time period for storing thermal energy as well as for dissipating infrared heat energy.
Further, the pentagonal shape of grill bars 200 facilitates cleaning of the grill bars 200 as a user can press a scrubbing tool down the outer angled surfaces of the grill bars 200.
The pentagonal shape of grill bars 200 also allows for beneficial, slow dripping of meat juices, marinades and/or other flavorings, with the juices collecting at a single point of drip down (the bottom tip) of each grill bar 200.
The pentagonal shape of grill bars 200 and spacing (in some embodiments, preferably about 2 mm) between side corners 224, 226 of adjacent grill bars 200 allows for such beneficial dripping of meat juices, as well as facilitating cleaning of the grill bars 200, as discussed above. This is a benefit over other grill bar shapes which may retain meat juices which can lead to fires on a grill grate and burning or overcooking of food.
These features of the present invention provide advantages over related grill bar shapes such a round (i.e., cylindrical) shaped bar grill grates and square shaped bar grill grates.
For example, with round shaped (cross sectional) bar grill grates, the meat juices drip relatively quickly which results in relatively less flavoring since the meat juices drop off of the grill bar quickly.
With square (cross sectional) bar grill grates, food pieces tend to get stuck in corners of the square bars and cause smoke and other problems, such as difficulty in cleaning.
Further, the shape and spacing of the grill bars 200 of the present invention provide for different types of foods to be properly cooked without the problem of food pieces (e.g., salmon steaks or vegetables) falling between the grill bars 200, which can be a problem with related grill grates having round or square grill bars.
Another benefit of embodiments of the present invention is that the pentagonal shape of and spacing between the grill bars 200 provide beneficial thermal heat storage.
By way of this thermal heat storage, the grill bars 200 continue to radiate heat after the fire or heat source of the grill is extinguished, allowing food to continue cooking, if needed.
In addition, the pentagonal shape of grill bars 200 provides for structural stiffness and rigidity which can be resistant to warping as compared to other grill bar shapes.
Further, the triangular bottom shape of grill bars 200 facilitates for heat dissipation along the grill bars 200.
In general, in the following claims, the terms used should not be construed to limit the invention to the specific embodiments disclosed in the specification and the claims. Accordingly, the invention is not limited by the disclosure, but instead its scope is to be determined entirely by the following claims.
