Barbecue grill and cart assembly

Abstract

The present invention is a frame assembly for a barbecue grill that provides rigid support for a cooking chamber and a work surface disposed adjacent to the chamber. The frame assembly comprises at least two U-shaped frame members, each formed of a bended contiguous tubular material, with at least one support member disposed transverse to the U-shaped members attached thereto, such that the two U-shaped frame members are in a spaced relation to each other to create a space therebetween to accommodate a cooking chamber and a work surface.

What is claimed is:  
     
         1 . A barbecue grill and frame assembly having a cooking chamber, the assembly comprising: 
 at least two generally U-shaped frame members each integrally formed from a single workpiece of material without welds or joints; and    at least one support member disposed transverse to the generally U-shaped frame members and attached thereto such that the two generally U-shaped frame members are in a spaced relation to each other;    wherein the cooking chamber is disposed between and attached to the two generally U-shaped frame members to support the cooking chamber.    
     
     
         2 . The grill assembly of  claim 1 , wherein a shelf is disposed within a space between the generally U-shaped frame members.  
     
     
         3 . The grill assembly of  claim 1 , wherein the support member includes a channel portion at each end of the support member to define an inner surface adapted to engage a portion of one of the frame members.  
     
     
         4 . The grill assembly of  claim 3 , wherein the support member further includes a clamping member that cooperates with the channel portion to engage the portion of one of the frame members.  
     
     
         5 . The grill assembly of  claim 1 , wherein the cooking chamber is a kettle-type cooking chamber.  
     
     
         6 . A barbecue grill assembly having a cooking chamber and a frame assembly, the grill assembly comprising: 
 first and second generally U-shaped frame members, each said frame member being formed of a single piece of continuous tubular material having a first bend defining a downturn for a first leg and a second bend defining a second downturn for a second leg, a middle portion passing between said first and second bends;    a plurality of cross members generally transverse to said legs and adapted to secure said first U-shaped frame member to said second U-shaped frame member;    the cooking chamber being secured to the middle portion of said first and second frame members.    
     
     
         7 . The grill assembly of  claim 6 , wherein a work surface is also secured to the first and second frame members.  
     
     
         8 . The grill assembly of  claim 6 , wherein the cross members each include a channel portion and a clamping member at each end of the cross members cooperating to define an inner surface adapted to engage a portion of one of the U-shaped frame members.  
     
     
         9 . The grill assembly of  claim 6 , wherein the cooking chamber is a kettle-type cooking chamber.  
     
     
         10 . A barbecue grill and frame assembly having a cooking chamber, the assembly comprising: 
 two generally U-shaped frame members each integrally formed from a single workpiece of material; and    at least one support member disposed transverse to the generally U-shaped members and attached thereto such that the two generally U-shaped frame members are in a spaced relation to each other and defining a space therebetween;    wherein the cooking chamber is disposed within the space between and attached to the two generally U-shaped frame members to support the cooking chamber.    
     
     
         11 . The grill assembly of  claim 10 , wherein the support member includes a channel portion at each end of the support member to define an inner surface adapted to engage a portion of one of the U-shaped frame members to facilitate attachment thereto.  
     
     
         12 . The grill assembly of  claim 10 , wherein a shelf is disposed within the space between the generally U-shaped frame members.  
     
     
         13 . A barbecue grill assembly having a cooking chamber, the assembly comprising: 
 first and second frame members each being formed of a single piece of continuous tubular material without any joints or welds, each of the frame members having a first bend defining a first leg, a second bend defining a second leg, and a middle portion passing between said first and second bends; and    at least one cross member disposed generally transverse to the legs of the frame members and adapted to secure the first frame member to the second frame member such that the frame members are in a spaced relation to each other;    wherein the cooking chamber is attached to the middle portion of the first and the second members.    
     
     
         14 . The grill assembly of  claim 13 , wherein a work surface is also secured to the first and second frame members.  
     
     
         15 . The grill assembly of  claim 13 , wherein the cross member includes a channel portion at each end of the cross member to define an inner surface adapted to engage a portion of one of the frame members.  
     
     
         16 . The grill assembly of  claim 15 , wherein the cross member further includes a clamping member that cooperates with the channel portion to engage the portion of one of the frame members.  
     
     
         17 . The grill assembly of  claim 13 , wherein the cooking chamber is a kettle-type cooking chamber.  
     
     
         18 . A barbecue grill assembly having a cooking chamber, the assembly comprising: 
 first and second frame members each being formed of a single piece of continuous material without any joints or welds, each of the frame members having a first bend defining a first leg and a second bend defining a second leg; and    at least one cross member disposed generally transverse to the legs of the frame members and adapted to secure the first frame member to the second frame member such that the frame members are in a spaced relation to each other;    wherein the cooking chamber is attached to the first and the second frame members.    
     
     
         19 . The grill assembly of  claim 18 , wherein a work surface is attached to the first and second frame members.
