Description of the Preferred Embodiment
Referring now by reference numerals to the drawings, and first to FIGS. 1-8, a barbecue grill support frame is indicated generally by numeral 1 and is for use with a barbecue grill G having a lower tub portion T and a top cover C. The top cover has a handle H for installing and removing the top cover. Support frame 1 is for mounting to upper and lower support rail members, U and L, respectively, of a deck D and posts P interconnected by an intermediate rail member I.
The support frame 1 includes an upper frame 3 including a pair of elongate side members 5A and 5B respectively. As shown in FIG. 1, side members 5A and 5B are spaced apart a distance substantially equal to the outer diameter of the tub portion of the grill G and extend outwardly from upper support rail U. The side members have an inner end and an outer end, the inner end of each side member being formed into a hook end, 7A and 7B respectively, which hooks over the inner end of the support rail U for attaching the side members to said upper support rail.
Support frame 1 also includes a transverse framing means 9 which includes an intermediate transverse member 11 extending between the respective inner faces of side members 5A and 5B and fixedly attached to said members. Transverse member 11 is positioned approximately one third along the length of the side members. The framing means 9 also includes a circular member 13 which is fixedly attached, as by welding, to the side members 5A and 5B at diametrically opposite points indicated by 14A and 14B. Member 13 includes an arcuate inner portion 13A which is attached to the transverse member 11 at the mid-point of said member. The member 13 further has an outer arcuate portion 13B which extends beyond the outer end of the side members 5A and 5B. The inner diameter of member 13 is substantially equal to the diameter of tub T for the tub to fit into the member. Typically, the upper circumference of the tub is outwardly turned to form a lip or rim R against which the cover seats. The tub rests in the circular member so the upper end of the tub is disposed somewhat above said circular member, thus to facilitate easy access to the grill portion of the tub.
The support frame 1 next includes a pair of elongate, inclined, telescopically adjustable leg members 15A and 15B respectively. Each leg has an upper portion 19 and a lower portion 17, and one end of each upper portion 19 is pivotally fastened to its associated side rail 5A or 5B by a pin 21. The upper portion 19 of the leg member is U-shaped to allow the lower portion 17 of the member to telescopically fit nestingly therewithin. A cross brace 20 is fixedly attached between said portions 19, as by welding, to stiffen said portions by forming them into an H-frame, and a keep plate 22 is attached, as by welding, between the toes of the U-shaped portion at the end thereof. The lower end of each upper portion 19 has a plurality of holes 23 and there are corresponding holes formed in the end of the upper portion 17. Fasteners 25, comprising a nut and bolt, are used to connect the upper and lower portions together to support upper frame 3. The lower end of each portion 17 is pivotally connected to an associated L-shaped bracket member, 27A and 27B, respectively, by a pin 29, each bracket having an outstanding apertured lug 28 for this purpose. The bracket members are each in an inverted position so to fit on lower support rail L.
The support frame 1 further includes open frame side panel members 31A and 31B respectively, which are removably attachable to side members 5A and 5B. The side panels are each rectangular in shape with a hollow center in which a pan P for meat or condiments can be fitted. As shown in FIG. 1, a circumferential lip 33 is formed on the lower portion of each panel to support the pan. Each panel is removably attached to its associated side member by means of two connectors. A first connector 35, best shown in FIGS. 5 and 6, comprises an L-shaped member which fits over the side member as shown in FIGS. 1 and 6. A second connector 37 has a flat portion 39 which extends laterally outward from the side panel and rests on the upper edge of each side member and a U-shaped portion 41 which abuts the outer face of transverse member 11 and extends underneath the member and up its front face. This double connection holding action serves to lock the side panels in place and prevent slippage.
A utensil holder 43 comprises a rectangular panel 45 which is secured to the outer faces 7A and 7B of the side members by stud connectors 47 which are received in slots 48. One or more hooks 49 extend from the face of panel for utensils to be hung from.
An alternative embodiment of the support frame indicated by numeral 101 is shown in FIGS. 9-13 which is used in conjunction with a wrought iron rail system having an upper rail member Uw, an intermediate rail member Iw and posts Pw bolted to lower rail member Lw of said patio deck D. In the alternative embodiment similar components of the support frame 101 are indicated by the same numerals as described above with the addition of suffix 100.
The support frame 101 includes an upper frame 103 including a pair of elongate side members 105A and 105B respectively. Hooked ends 107A and 107B, as clearly shown in FIGS. 11 and 12 are formed from a vertical member 106, attached to an associated side member such as 105A as by welding, and an L-shaped member 108 which is attached to said member by means of a wing nut fastener 110. The side member 105A also includes an opening 112 so that the member 105A can be optionally connected to a wood rail U, in lieu of the wrought iron rail Uw, as shown in FIG. 13 by a screw 114.
Support frame 101 also includes a transverse framing means which includes a pair of transverse members 111 and 113 fixedly attached between members 105A and 107A. Member 113 is disposed adjacent the outer end of the side members and spaced from member 111 substantially the same distance as the side members are spaced from each other so that the tub T of the barbeque grill is supported at four points.
The telescopically adjustable leg members 115A and 115B of support frame 101, each include a tubular upper portion 119 and a larger diameter tubular lower portion 117 which receives the upper portion 119 in sliding relation. The upper end of each upper portion 119 is flattened and pivotally fastened to its associated side rail as by a pin 121, such as a wing nut fastener. As shown in FIG. 13, the upper and lower portions are connected by a wing nut fastener 125 extending through an opening 123 provided in the lower portion 117 and one of a plurality of corresponding openings provided in the lower end of said upper portion 119. The lower portion 117 is flattened and pivotally connected to a bracket 127A, substantially as described above with respect to support frame 1 and a cross brace 120 is fixedly attached between said lower portions 117, as by welding, to form an H-frame. In the embodiment shown an additional connection for the support frame 101 is provided by an adjustable flexible tie strap 122 of plastic or the like which extends between cross brace 120 and the intermediate rail Iw and thereby operatively to said lower support member L of the deck D.
As shown in phantom outline in FIG. 9 a side panel member 131A can be removably attached to the outside of associated side members 105A, the manner of attachment being substantially as described above with respect to support frame 1.
In view of the above it will be understood that various aspects and features of the invention are achieved and other advantageous results are attained. While preferred embodiments of the invention have been shown and described, it will be clear to those skilled in the art that various modifications may be made without departing from the invention in its broader aspect.
