The inventions disclosed herein relate to restraint devices for gas tanks. In a first embodiment, the tank retainer includes a bracket for engaging with the collar of a gas tank and a tray for engaging with the base of the gas tank. The bracket is preferably stationary wherein the tank, while supported by the tray, is rotated into engagement with a slot formed into the bracket. The tray preferably includes a channel for receiving and restraining the base of a gas tank. The brackets and trays can be used in combination or independently of one another. The bracket and tray are preferably distinct components of a gas grill; however, it is contemplated that the features of the bracket and tray can be incorporated into other components of a barbecue grill such as the frame members and lower shelf of the grill cart.
1. A tank retainer on a frame assembly for a barbecue grill, the tank retainer adapted to retain a tank having a generally circular base flange at the bottom of the tank and a partial guard collar at the top of the tank, the tank retainer comprising:
a fixed pathway configured to receive the partial guard collar;
a first structure adapted to engage an outside surface of the generally circular base flange;
a second structure adapted to engage an inside surface of the generally circular base flange;
a bracket, wherein the bracket comprises a first barrier for engaging with an outside surface of partial guard collar and a second barrier for engaging with an inside surface of the partial guard collar, the first barrier and the second barrier being laterally spaced from each other to define the pathway; and,
wherein the first barrier comprises a back wall and two diverging wings extending from opposite ends of the back wall, the diverging wings being adapted to guide the partial guard collar into the pathway and allow the partial guard collar to enter the pathway from either side.
2. The tank retainer of claim 1 , wherein the second barrier comprises a generally vertical oriented tab that is bounded on either side by corresponding diverging wings that are generally parallel to the diverging wings of the first barrier, the corresponding diverging wings also being adapted to guide the partial guard collar into the pathway and allow the partial guard collar to enter the pathway from either side.
3. The tank retainer of claim 2 , wherein the bracket further includes a mounting segment and horizontal segment, the mounting segment being adapted for connection to a frame member of the barbecue grill, the horizontal segment depending from the mounting segment, the back wall depending from the horizontal segment, the horizontal segment laterally displacing the back wall from the mounting segment, whereby the tank slightly extends beyond an edge of the barbecue grill to facilitate easy access to the tank.
4. A tank retainer on a frame assembly for a barbecue grill, the tank retainer adapted to retain a tank having a generally circular base flange at the bottom of the tank and a partial guard collar at the top of the tank, the tank retainer comprising:
a fixed pathway configured to receive the partial guard collar;
a first structure adapted to engage an outside surface of the generally circular base flange;
a second structure adapted to engage an inside surface of the generally circular base flange;
a molded plastic tray and a bracket, the molded plastic tray including the first and second structures and being adapted to snap onto a wire rack of the barbecue grill, and the bracket including the pathway and being adapted to be connected to a frame of the barbecue grill; and,
wherein the barbecue grill includes a fuel supply hose that is of a length that allows a connection to be made between the tank and hose, when the tank is supported in the molded plastic tray, only when the partial guard collar of the tank is received within the pathway of the tank retainer.
