Description




FIELD OF THE INVENTION




The present invention is generally related to the field of barbecue grills, and more particularly to quick assembly grill carts requiring few or no tools for assembly.




BACKGROUND OF THE INVENTION




Commonly, barbecue grills are not assembled when they are purchased. This makes commercial sense in that each barbecue grill requires less space during shipping and storing, meaning more units may be transported in each shipment, thereby saving money for both the manufacturer and the retailer of the barbecue grill. In addition this provides for easier transportation of the barbecue grill from the store by the purchaser. However, this also results in a number of potential problems. The purchaser has to either partially or fully assemble the barbecue grill prior to use. This can require added expense and possibly significant time on the part of the purchaser. For example, should the purchaser not already possess the tools required to assemble the barbecue grill, the purchaser will have to either borrow or purchase them. As well, quite frequently, the assembly of the barbecue grill may be beyond the mechanical acumen of the purchaser, thereby causing frustration and reduced consumer satisfaction in the overall product.




Furthermore, assembly by the purchaser increases both the chances of parts being lost during assembly and the barbecue grill being improperly assembled. Lost parts can lead to time and effort on the part of both the purchaser and manufacturer. First, the purchaser must secure another part before assembly can be completed and the barbecue grill used. Hopefully, the missing part is in the retailer's stock system so that the part may be rapidly replaced. However, in all likelihood, the part will have to be procured from the manufacturer, leading to lengthy delays in the use of the barbecue grill. Second, because the grill is brand new, the purchaser will likely believe the missing part was not originally provided. Therefore, the manufacturer, in all likelihood, will have to replace the part free of charge. Worse yet, should the barbecue grill be assembled either without all the required parts, or just improperly, safety concerns arise, such as the barbecue grill being unstable; improper gas train assembly causing a fire hazard; etc.




Therefore, a need exists for a barbecue grill requiring few or no tools to assemble and including a minimal number of separate parts that require assembly.




SUMMARY OF THE INVENTION




Briefly described, the barbecue grill cart provides an easily and rapidly assembled support structure for barbecue grills. An embodiment of the barbecue grill cart includes a right leg frame assembly including a right lower frame assembly and a right upper frame assembly. The right lower frame assembly further includes a right front lower leg and a right rear lower leg, the right front and right rear lower legs being connected by a right lower horizontal member. The right upper frame assembly includes a right front upper leg and a right rear upper leg, the right front and the right rear upper legs being connected by a right support member. The barbecue grill cart also includes a left leg frame assembly including a left lower frame assembly and a left upper frame assembly. The left lower frame assembly includes a left front lower leg and a left rear lower leg, the left front and left rear lower legs being connected by a left lower horizontal member. The left upper frame assembly includes a left front upper leg and a left rear upper leg, the left front and left rear upper legs being connected by a left support member. The right front and the right rear lower legs telescopically engage the right front and the right rear upper legs, respectively, thereby forming a right front leg and a right rear leg. Similarly, the left front and the left rear lower legs telescopically engage the left front and the left rear upper legs, respectively, thereby forming a left front leg and a left rear leg. As such, each of the front and rear legs has an overlapping region. A front panel and a rear panel, both having flange means at each end configured to receive a corresponding leg, are included. Securing means are passed through the flange means of the front and rear panels, as well as through the corresponding legs on opposing ends of said overlapping region, thereby creating a secure barbecue grill cart structure.




Other objects, features, and advantages of the present invention will become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such objects, features, and advantages be included herein within the scope of the present invention, as defined in the appended claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now more specifically to the drawings, and to

FIGS. 1 and 3

in particular, numeral


10


designates generally the present barbecue grill cart, shown here supporting a barbecue grill


12


. The major difference between the right leg frame assembly


20


and the left leg frame assembly


30


is the provision of a wheel assembly


14


on the left leg frame assembly


30


, as well as the fact that the left leg frame assembly


30


is configured to support an LP gas tank


11


. Note that the right leg frame assembly


20


can be similarly configured if desired.




The right and left leg frame assemblies


20


,


30


further include upper frame assemblies


40


, each including a front upper leg


42


and a rear upper leg


44


rigidly joined by a horizontal support member


58


configured to receive the barbecue grill


12


. The right and left leg frame assemblies


20


,


30


further include a right lower frame assembly


22


and a left lower frame assembly


32


, respectively. Each lower frame assembly


22


,


32


includes a front lower leg


46


and a rear lower leg


48


. The front lower leg


46


and rear lower leg


48


of the right lower frame assembly


22


are rigidly connected with a lower horizontal member


24


, while the front lower leg


46


and rear lower leg


48


of the left lower frame assembly


32


are connected by the above-mentioned wheel assembly


14


.




Referring now to

FIG. 2A

, the upper end of a front lower leg


46


and the lower end of a front upper leg


42


are shown along with the corresponding portion of the front panel


50


. The front lower leg


46


shown includes an extension


47


and a lip


49


. The outer diameter


47




a


of the extension measures less than the inner diameter (not shown) of the front upper leg


42


, thereby allowing the front lower leg


46


to be inserted into the front upper leg


42


. Note that the lip


49


limits the extent to which the front lower leg


46


is inserted into the front upper leg


42


, thereby limiting the overlapping region (not shown) of the front upper


42


and front lower legs


46


to the length of the extension


47


. The extension can also be placed on the front upper leg


42


rather than the front lower leg


46


, thereby requiring insertion of the front upper leg


42


into the front lower leg


46


for assembly.




After the front upper leg


42


and front lower leg


46


have been telescopically connected, securing means are used in conjunction with panels to hold the front upper leg


42


and the front lower leg


46


together. Apertures


34


are provided, one each, in the front upper leg


42


and the front lower leg


46


. The aperture


34


disposed in the front lower leg


46


is located below and adjacent the lip


49


. The aperture


34


disposed in the front upper leg


42


is located above and adjacent the leading edge of the extension


47


, after the extension has been inserted into the front upper leg


42


. As such, there is an aperture


34


located above and below each of the overlapping regions. Panels are provided, each panel having flange means


52


at each end. Each flange means


52


is configured to fit over a portion of a corresponding leg that includes the apertures


34


disposed, in this case, the front upper leg


42


and the front lower leg


46


. Further, each flange means


52


has corresponding apertures


35


aligned with the apertures


34


of the upper legs and lower legs. After the flange means


52


are positioned, securing means are passed through both the apertures


34


and corresponding apertures


35


of the flange means


52


, thereby securing the front upper leg


42


and the front lower leg


46


together. The upper and lower legs of each leg on the grill cart


10


are similarly assembled.




As shown in

FIG. 1

, a front panel


50


and a rear panel


54


are used to create a rigid barbecue grill cart


10


for receiving a barbecue grill


12


. The front panel


50


and rear panel


54


not only connect the upper legs to the lower legs, they serve to connect the right leg frame assembly


20


to the left leg frame assembly


30


. For added stability, a side panel


56


is provided opposite the leg frame assembly configured to support the LP gas tank


11


(FIG.


3


). This side panel


56


is connected to its respective leg frame assembly using apertures


34


(

FIGS. 2A and 2B

) and the securing means that are used to connect the corresponding flange means of the front panel


50


and rear panel


54


to the respective leg frame assembly. In the embodiment shown, threaded bolts


36


with nuts configured to be hand tightened


37


are preferred. However, numerous securing means would suffice (i.e., longitudinal members with cotter keys, threaded bolts and nuts, etc.). Similar securing means can also be used to secure the bottom casting


13


of the barbecue grill


12


to the barbecue grill cart


10


by passing the threaded bolts


36


down through matching apertures (not shown) in both the bottom casting


13


and each of the horizontal support members


58


. As such, no tools are required to assemble the barbecue grill cart


10


, or attach a barbecue grill


12


thereto.




As previously noted, a wheel assembly


14


is provided that includes a strut member


16


extending along the longitudinal axis of the wheel assembly


14


. The strut member


16


is configured to receive the bottom portion of a LP tank


11


(

FIG. 3

) and is rotatably secured about the longitudinal axis. This permits the strut member


16


to be rotated to one side to receive an LP tank


11


and then be rotated back such that the tank


11


is vertical. The tank


11


is further secured in place by a tank wire


17


that is attached to both legs of the corresponding leg frame assembly. Ideally, the tank wire


17


is configured such that the securing means used to attach the front panel


50


and rear panel


54


to the corresponding leg assembly can be used; however, additional apertures (not shown) can be provided in the legs for receiving the tank wire, as is known in the art.




For added convenience, side shelves


18


are provided. Ideally, the upper frame assemblies


40


of both the right and left leg frame assemblies


20


,


30


include a side shelf


18


.
