  • Patent number: 8347874
    Abstract: The inventions disclosed herein relate to frame assemblies for gas barbecue grills which incorporate structures for preventing a consumer from storing replacement fuel tanks on the grill, in order to minimize fire and tipping hazards. Because it is known that many consumers never install or even remove prior art tank blockers, the tank blocker of the present invention is adapted to serve as a function of the grill (in addition to the function of blocking a tank) or to support a component of the grill. The preferred embodiment of the tank blocker described herein is adapted to support a component of the grease management system, namely the grease drip pan. Consequently, it is believed that consumers will be forced to install or will be prevented from removing the tank blocker, lest the grease management system become inoperable (or function improperly), causing grease to spill onto the cart.

  • Patent number: 7810486
    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.
