Definitions

  • Grilling is a cooking style that is especially popular in the United States. But grills are not particularly portable or easy to set up, in part because the framework for the grill is large and fastened to the grill in a way that makes assembly and disassembly difficult.
  • the present invention provides apparatus, systems, and methods of an easy to assemble grill cart for a barbeque or other grill.
  • the device preferably includes a base frame, side frames, support arms, and fasteners. To use, the grill cart is unfolded and latched into place such that a grill can be received and fastened into place at the top of the cart.
  • the base frame provides a support platform for the other components.
  • the two side frames preferably couple to opposite ends of the base frame, preferably by a hinge or another suitable rotating or pivoting connection.
  • the base frame has two or four movably coupled support arms.
  • the side frames can fold down inward to lie against the base frame when not in use, but when deployed, they are configured to stand upright, forming approximately a right angle with the base frame.
  • Both of the side frames can also include a small protrusion, to which the support arms can couple.
  • the support arms provide structural (e.g., shear) rigidity to the structure.
  • the support arms can be coupled to the side frames.
  • the base frame includes protrusions that the support arms couple to.
  • the two side frames additionally include either hooks or fasteners to secure the grill when the grill is placed at the top of the deployed grill cart.
  • the fasteners can be latching fasteners or any other appropriate fastener known in the art. In embodiments with hooks, the fasteners would likely be part of the grill itself instead of part of the grill cart.

  • the base frame 102 of the cart 100 can be seen in Figures 1A-E. Each figure shows a different stage of deployment.
  • Figure 1A the cart 100 is folded up with a grill 104 resting on top.
  • Figure IB shows the grill 104 lifted off the top of the undeployed cart 100.
  • Figure 1C shows the side frames 106 deployed.
  • Figure ID shows the support arms 108 in position.
  • Figure IE shows the grill 104 placed on top of the fully deployed cart 100.
  • the base frame 102 is a rectangular metal frame.
  • the base frame 102 can optionally include structural components to provide sheer strength (not pictured), but those components can generally be made unnecessary by using a strong material to build the base frame 102 (e.g., steel).
  • the base frame 102 can additionally include wheels 1 14.
  • the wheels 1 14 can be placed at each corner of the base frame 102.
  • mobility is not as important and the wheels 1 14 can be replaced with static structural components (e.g., pegs, or extended portions of the base frame 102).
  • the base frame 102 also includes components designed to facilitate connection with two side frames 106.
  • the side frames 106 are designed to fold up and down. When the side frames 106 are up, they provide a platform for a grill 104 to rest on top of (as shown in Figure IE), and when the side frames 106 are down, a grill 104 can rest on top of the side frames 106 and the base frame 102 (as shown in Figure 1A).
  • the side frames 106 can be coupled with the base frame 102 by, for example, hinges, by slots fitting over pegs, or by any other means now known in the art that can allow the side frames 106 to rotatably couple to the base frame 102. It is sufficient that the side frames 106 are coupled with the base frame 102 such that they can fold down to lie against the base frame 102 and also be rotated upward to form approximately a right angle to the plane of the base frame 102.
  • the deployed position of the side frames 106 is not vertical (i.e. , the side frames 106 do not create approximately a 90 degree angle with the base frame 102).
  • the side frames 106 can alternatively be deployed to some angle away from vertical (e.g. , 5-10, 10-15, 15-20, 20-25, 25-30 degrees from vertical in either direction).
  • the side frames 106 are preferably formed to be less than the half the length of the base frame 102, as seen best in Figure IB where the side frames 106 are folded down.
  • the side frames 106 By creating the side frames 106 to have a length (as measured from the point where the side frame couples with the base frame 102 to the end of the side frame that is the farthest from the base frame 102) that is less than half of the length of the base frame 102, both of the side frames 106 can be folded down toward each other without overlapping and causing unwanted interference.
  • other embodiments of the cart 100 include side frames 106 that are longer than half of the length of the base frame 102 to provide a taller deployed cart 100.
  • the side frames 106 can have a length that is, for example, 75-70%, 70-65%, 65-60%, 60-55%), 55-50%, 50-45%, 45-40%, 40-35%, 35-30% the length of the base frame 102, where the length of the base frame 102 is measured between the ends where the side frames 106 couple to the base frame 102.
  • the side frames 106 additionally include components to allow a grill 104 to fasten to the cart 100.
  • Figure IB shows side frames 106 having hooks 1 12 that enable fasteners on the grill 104 to couple to the cart 100.
  • Figure IE shows the fasteners on the cart 100 coupling to the hooks 1 12.
  • the side frames 106 can themselves have fasteners instead of hooks 1 12.
  • fasteners e.g. , latching fasteners, elastic fasteners, screwing fasteners
  • the grill 104 need only have receiving components (e.g. , hooks, or protrusions).
  • Another way to fasten the cart 100 to the grill 104 would be to have small rotating arms with hook portions that swivel up to the grill 104 to hook onto a protrusion (e.g., a protrusion formed into the structure of the grill 104, or a screw that sticks out).
  • This fastening method can also be reversed so that the swiveling arms with hooks are on the grill 104 with the receiving protrusions on the tops of the side frames 106.
  • the side frames 106 are not two pieces as shown in Figures 1A-E. Instead each side frame can include two separate legs that extends independently of the other.
  • support arms 108 couple the side frames 106 to the base frame 102. At least two support arms 108 are necessary (one for each of the side frames 106), but including additional support arms 108 would not be a departure from the inventive concepts described in this application.
  • the support arms 108 can be rotatably coupled to the base frame 102 by a hinge or any other connector known in the art. When the side frames 106 are deployed, the support arms 108 can then couple with the side frames 106 to provide structural rigidity to the cart 100.
  • the support arms 108 are rotatably coupled with the side frames 106, and when the side frames 106 are deployed the support arms 108 can then couple with the base frame 102.
  • One way to couple the support arms 108 with either the side frames 106 or the base frame 102 is by providing a hook portion on each support arm 108 and a peg on the component the support arm 108 is to be coupled to, so that the hook can go over the peg. This configuration can be seen in Figure 1C, where each support arm 108 has a hooked end 1 10 to couple with a peg on each of the side frames 106 (not shown).
  • the cart 100 can forego support arms 108 entirely.
  • the side frames 106 can be locked into the deployed position by a pin or a clip (e.g., when the side frame is moved into the upright position, it clicks or locks into place by a suitable component known in the art).
  • an additional top piece can be used to couple the tops of the side frames 106.
  • This top piece (not shown) can be a flat piece that creates a top platform or surface, or it can be a frame (e.g., with cross members to provide structural rigidity to the top piece).
  • the cart 100 gains additional shear rigidity, which is especially preferable in embodiments where the side frames 106 include independently deployable legs.
  • the top piece can couple to the tops of the side frames 106 by fitting around the tops of the side frames 106 and optionally covering the tops of the side frames 106 (e.g., the top piece has slots that receive the tops of the side frames 106, where the slots are either configured as through holes or as upside down cup pieces).
  • FIG. 2A In another embodiment, telescoping slot and connector side frames are employed as shown in Figures 2A-N.
  • cart 200 is in the collapsed configuration for shipping/storage.
  • Cart 200 includes base frame 202 and optionally includes wheels 214.
  • Grill 204 (comprising a firebox base and firebox hood) is shown stacked on collapsed cart 200.
  • the firebox hood can be further collapsed (see e.g., Figure 11) to save space during shipping and/or storage.
  • Cart 200 is shown in the fully deployed configuration in Figure 2B.
  • Telescoping side frames 206 support grill 204, and doors 207 are installed at the front of cart 200.
  • Different stages of deployment are shown in Figs. 2B-N.
  • the right perspective view of cart 200 in the collapsed configuration is shown in Figure 2C.
  • the grill 204 is removed from collapsed cart 200 and set aside ( Figure 2D).
  • Left and right side frames 206 are folded up ( Figure 2E).
  • each side frame is expanded in a telescoping fashion (Figs. 2F-G).
  • each side frame locks automatically as it reaches the fully extended state, although other locking mechanisms (e.g., pin/dowel in hole, spring snap clip, screw) are not excluded.
  • the left and right side frames can also comprise three or more telescoping panels. Additionally, the inventors contemplate that non- telescoping panels can be employed in collapsible grill carts consistent with the inventive subject matter.
  • Support arms 208 are inserted in grooves at the top of the left and right side frames across the top of the front and back of the grill cart (Figs. 2H-I). Support arms 208 may also be coupled to side frames 206 by other suitable means (e.g., screws).
  • doors 207 are installed at the front of the grill cart by appropriate means (e.g., hinge pins). Alternatively, doors 207 can be mounted on base frame 202 and/or support arms 208.
  • contemplated grills comprise firebox hoods and firebox bases.
  • Each firebox base further comprises one or more griddles and one or more burners, wherein the burners are configured to couple with gas regulators, which in turn are configured to couple with standard propane tanks. It should be appreciated that any suitable means of coupling grills to carts according to the inventive subject matter may be employed.
  • the firebox base can nest in a lip extending at least partially around the circumference of the cart top.
  • Figures 3A-3B show a nesting top configuration for securing grill 304 to cart 300.
  • Cart 300 has flaring lip 312, which extends around the perimeter of the cart top.
