ABSTRACT:
The inventions disclosed herein generally relate to isolating heat sensitive components from the heat source of a barbecue grill. In the preferred embodiment, ceramic bushings are used to isolate a glass-reinforced nylon grill stand from the cooking chamber of a barbecue grill. The bushing incorporates a beveled upper edge for engaging with lobes which downwardly depend from the cooking chamber. The bushing also incorporates a circular lower portion for engagement with an aperture in the grill stand. The bushing is locked into engagement with the cooking chamber using a threaded bolt and is locked into loose engagement with the grill stand using a spring clip. The combination of the beveled upper edge and the loose engagement with the grill stand allows the bushing to float with respect to both the grill stand and cooking chamber. As a result, manufacturing tolerance requirements can be relaxed.
