Grill Structure

Abstract

A cart suitable for supporting a grill, including a firebox. The cart has four panels each of which has all four of its edges bent to form a flange that provides structural rigidity and a connection feature for facilitating the assembly of the cart. Two opposing side panels are carried by and preferably welded to a respective side frame. The side frames are joined by upper crossbars, one at the front of the cart and a second at the rear of the cart. A bottom panel fits into and is carried by troughs formed by upturned lips on the lower edges of the side panels. The structural integrity and racking strength of the cart is enhanced by the attachment of a rear panels, which has a lower lip that locks into engagement with the rear edge of the bottom panel. The top edge of the rear panel is fastened to the rear upper crossbar to complete the basic structure of the cart. Hooks welded to the side frames allow easy and secure attachment of side and front attachments to the cart.

Claims

1. A cart comprising: two side panels, each having a lower edge with an up-turned lip, the side panels being carried by two generally inverted and U-shaped side frames, the side frames being joined by front and rear crossbars, a rear panel with a lower inwardly facing lip, a bottom panel having downwardly depending rear and side edges that fit into troughs formed by said lips.

2. A cart according to claim 1 wherein the side panels are welded to the side frames.

3. A cart according to claim 1 wherein at least one hook carried by at least one of the side frames carries a side attachment.

4. A cart according to claim 1 wherein each of the panels, both side and bottom, has all four of its edges bent to form a flange, each of said flanges extending at least a major portion of the length of the edge of the panel from which it is formed.

5. A cart according to claim 1 wherein each side frame has three hooks, two hooks facing outwardly for use in supporting a side attachment, and a front hook for carrying and supporting a front attachment.

6. A method of assembling a cart having two side frames each with a side panel, a rear panel and a bottom panel, each side panel having an upturned inwardly extending lip at the lower edge thereof, and an upturned inwardly extending lip at the lower edge of the rear panel, the method comprising the following steps, not necessarily in the following order: affixing the side panels to the side frames,connecting one end of a front crossbar to a front upper portion of each the side frames,connecting one end of a rear crossbar to a rear upper portion of each the side frames,placing one end of the bottom panel in an upwardly facing trough at the lower end of each of said side frames,lifting a trough formed by the lip on the rear panel into engagement with a rear edge on the bottom panel and connecting the upper end of the rear panel to the rear crossbar.

7. A method according to claim 6, wherein the rear panel has an upper horizontal flange, including the additional step of placing the upper flange of the rear panel onto the rear crossbar.
