[0001] The present invention relates to tools for cleaning and removing debris from grill grates such as the grill grates of gas, charcoal or wood burning barbecue grills. More specifically, a tool that is used to determine the contour of barbecue grill grates wherein during use, the grill grate scraper conforms to the physical layout of the cooking grate. Still more specifically, once the contour of barbecue grill grate is determined the profile of the tool can be locked into position duplicating an inverse footprint of the grill grate configuration.
BACKGROUND
[0001] The present invention relates to tools for cleaning and removing debris from grill grates such as the grill grates of gas, charcoal or wood burning barbecue grills. More specifically, a tool that is used to determine the contour of barbecue grill grates wherein during use, the grill grate scraper conforms to the physical layout of the cooking grate. Still more specifically, once the contour of barbecue grill grate is determined the profile of the tool can be locked into position duplicating an inverse footprint of the grill grate configuration.
BACKGROUND
[0002] Outdoor barbecue grilling is a very relaxing and entertaining social activity. Barbecuing tends to bring family and friends together for enjoyable gatherings. The barbecue grill offers another method of cooking food, based on different techniques such as smoking, roasting, braising and grilling, resulting in unique flavors and textures which cannot be easily duplicated in a traditional kitchen.
Grill grates serve as a cooking surface for the barbecue. A grill grate is usually made of an assembly of parallel metal rails welded to one or more common metal bars perpendicular to the parallel rails. There are a variety of different grill grate profiles and spacing configurations, such as angular, circular and rectangular rails.
There is often little uniformity among various brands and models of barbecue grill grates. It is not uncommon to find the distances and grill grate profiles between one model to be quite different from that in others.
While grilling, food particles, charred debris, food residue and grease tend to stick to grill grates. Grill cleaning is another way to remove harmful carcinogens which can build up on your grill over time. Unsanitary barbecue grill grates can accumulate disease causing bacteria and viruses. Frequent cleaning to remove such deposits and residues is necessary to maintain a clean cooking surface. Also, regular maintenance will greatly benefit the integrity and life span of the grill grates.
As a result of the varied grill grate profiles, predetermined grill grate scraping devices that is suitable for one grill grate may have little or no value for cleaning another. Wire brushes suffer from the bristles bending and breaking. Loose wire bristles can stay on the grill grate and become lodged into the food. These wire bristles can be ingested, causing life threating fatalities. There exists a need by which grills grates can be quickly and easily cleaned after use. Therefore, what is clearly needed is an adjustable barbecue grill grate scraper that solves the problems mentioned above.

DETAILED DESCRIPTION AND BEST MODE OF IMPLEMENTATION
DETAILED DESCRIPTION AND BEST MODE OF IMPLEMENTATION
[00024] The inventor provides a unique adjustable barbecue grill grate scraper enabling the tool to copy variously configured barbecue grill grate profiles, locking the profile and reproducing an exact inverse profile of a grill grate. The tool is able to clean any style of multiple grill grates rails simultaneously. The present invention is described in enabling detail in the following examples, which may represent more than one embodiment of the present invention.
Figure 1 is a rear, top, and left side isometric view of an adjustable barbecue grill grate scraping tool 100; Figure 2 is a front, top and right side isometric view of the adjustable barbecue grill grate scraping tool 100 in accordance with the preferred embodiment of the present invention; Figure 3 is a detailed view "A"
of the securing mechanism of the adjustable barbecue grill grate scraping tool shown in FIG. 2.
The adjustable barbecue grill grate scraper 100 comprises a plurality of elongated blades of uniform lengths juxtaposed 101, each relatively long and narrow with a right triangle at one end of the blade 101 in this example and each provided with a longitudinal slot 101a as shown in FIG. 4. For the purpose of supporting the blades 101 in their operative relationship to each other, they are all threaded on a screw 102 in this example, and the screw of such a diameter that it permits each blade 101 to slide freely and independently. It is important to note that the blade slot 101a is wider than the diameter of the screw allowing the plurality of blades 101 to each slide freely and independently in an upward or downward position. For the purpose of supporting the blades in their parallel relationship in this example a U-shaped support bracket 103 is perpendicularly oriented with respect to the plurality of the blades.
Figures 5 to 8 are close-up isometric views of alternate embodiments of the invention showing blades of varied configurations where each blade is relatively long and narrow and each provided with a longitudinal slot could be swapped for the blade 101 as shown in Figs 1 and 2. Figure 5 blade 101b having a right triangle at one end and an inverse right triangle at the other end of the blade and the blade having a longitudinal slot 101c. Figure 6 blade 101d having two right triangles one at each end of the blade and the blade having a longitudinal slot 101e.
Figure 7 blade 101f having two rectangular tips one at each end of the blade and the blade provided with a longitudinal slot 101g. Figure 8 blade 101h having two right triangles one at each end of the blade with both right triangles having filets and the blade having a longitudinal slot 101j.
Figure 9 is an exploded isometric view illustrating component parts with apertures and slots of the adjustable barbecue grill grate scraping tool shown in FIGS. 1 and 2. In this example a right hand frame 104 and a left hand frame each have two equal elongated slots cutout 104b, 104c, 105b and 105c respectively.
The elongated slots provide an opening for the U-shape support bracket 103 to be inserted. The U-shape support bracket 103 supports the blades 101 to each slide freely and independently and reinforces them against any rotational swinging movement with reference to each other in one embodiment of the present invention.
Thereby, the blades are held in their parallel relationship at all times.
The left hand frame 105 having a threaded aperture 105a for receiving an externally threaded screw 102 and the right hand frame 104 having a non-threaded aperture 104a to receive the other end of the screw 102 in this example. The apertures in the left and right hand frame provide a hole for the screw to be inserted for the purpose of supporting the blades 101. The screw 102 is firstly threaded into the aperture 105a of the left hand frame 105 and secondly is inserted into a longitudinal slot 101a of a plurality of elongated blades 101 of uniform lengths juxtaposed and thirdly the end of the screw 102 is inserted into the non-threaded aperture 104a of the left hand frame 104. The screw 102 allows the blades 101 to be held in their operative relationship to each other. The U-shape support bracket 103 contains a non-threaded aperture 103a which allows the end of the screw 102 to go through.
Attached to the end of the screw 102 is a wing nut 106, rotating the wing nut 106 in a counter clockwise position loosens the wing nut and allows the plurality of blades 101 to each slide freely and independently in an upward or downward position, rotating the wing nut 106 in a clockwise position presses the blades together sidewise applying pressure for securing the plurality of elongated blades 101 locking the plurality of blades such that the blades will not move in an upward or downward position. The assembly of the components are more clearly illustrated in FIGS. 1 and 2.
The ends of the right and left hand frames 104 and 105 when mated together are secured into a slot 107b in an elongated handle 107 in this example, such that the tool portion extents outwardly from the handle. The slot 107b extends from one end of the handle through more than half the portion of the length of the elongated handle 107 in this example. Preferably, the slot 107b is just slightly wider than the thickness of both right and left hand frames 104 and 105 respectively when mated together. The right and left hand frames 104 and 105 may be provided with a plurality of non-threaded apertures 104g and 105g respectively for attachment of = CA 3015630 2018-08-28 elongated handle 107 aligned with non-threaded apertures 107a and secured by conventional fasteners, such as rivets 108a and 108b in this example. The handle 107 may include an optional non-threaded aperture 107c or other similar arrangement for allowing the adjustable barbecue grill grate scraper to be hung on a support hook for storage.
The right and left hand frame 104 and 105 includes an obtuse angle 104d and 105d respectively to the rest of the frame with the angle of approximately 145 degrees in this example. This ergonomic feature allows a user of such a tool to comfortably apply pressure in a forward and rearward motion while cleaning the grill grates.
The right and left hand frames 104 and 105 in this example are bent inwardly towards each other 104e and 105e respectively at approximately 142 degree angle and 2.5 inches lower the frames are bent outwardly 104f and 105f at approximately 142 degree angle in the opposite direction. The angles in the right and left hand frame 104 and 105 at one end form a V-shape and the other end of the right and left hand frame are mated together. The V-shape formed within the frames creates a predetermined space approximately 3 inches wide in this example to allow a plurality of elongated blades 101 of uniform lengths juxtaposed to be assembled within the V-shaped cavity and the other end of the frames are mated together and secured into the slot 107b of the handle 107.
Figures 10, 12 and 14 are enlarged isometric views of partial grill grates and a partial adjustable grill grate scraper engaged on different configured metal grill grates with parallel rails whereby the ends of the blades define the grill grates;
Figures 11, 13 and 15 are front views of the partial adjustable grill grate scraper as shown in Figures 10, 12 and 14. The use of the presently disclosed adjustable barbecue grill grate scraper is for the purpose of cleaning grill grates as illustrated in FIGS. 10 to 15. More specifically, the partial adjustable barbecue grill grate scraper 117, 118 and 119 are positioned over different grill grate profiles 120, 121 and 122 as shown in FIGS. 10 to 15.
