A cart suitable for supporting a grill, including a grill bowl. The cart has two union members with curved channels for receiving tubular, U-shaped frame members. The union members may be in the form of two similar (but not necessarily identical) halves joined together to enclose the frame members.
A cart suitable for supporting a grill, including a grill bowl. The cart has two union members with curved channels for receiving tubular, U-shaped frame members. The union members may be in the form of two similar (but not necessarily identical) halves joined together to enclose the frame members. The tubular channels of the union members resist movement (such as twisting and tilting) in at least two directions. The union members lock the frame members in place with internal protrusions that fit into mating depressions or holes in the frame members. Extra rigidity is added to the cart by one or more side tables which are structural members as well as functional tables. The side tables thus serve as cross-members between two frame assemblies. The grill's lid can easily be tilted back to rest in place on lid supports underneath the bottom edge and contact points on the side tables.

1. A cart comprising: a first union member, wherein the first union member has at least two internal channels;a second union member;an upper frame and a lower frame rigidly connected together by the first union member, the connected upper frame and lower frame forming a first frame assembly, wherein the internal channels are capable of receiving a portion of the upper and lower frames, and wherein the first union member resists rotation of its associated upper frame and lower frame; anda second upper frame and a second lower frame rigidly connected together by the second union member, the connected upper frame and lower frame forming the second frame assembly;at least one cross-member extending between the first frame assembly and a second frame assembly,wherein each union member comprises two substantially similar halves capable of being joined together to connect the associated upper frame and lower frame, and wherein each union member comprises at least two protrusions, each protrusion engaging with an associated depression in the upper frame and the lower frame;wherein each upper frame comprises a tube that is substantially “U” shaped, and wherein the union members are attached to the upper frames at a point substantially equidistant from the ends of the “U” shaped tubes;at least two substantially rigid side tables connected to the upper frames of the first frame assembly and the second frame assembly, the at least two substantially rigid side tables comprising the at least one cross-member, the at least two substantially rigid side tables further comprising structural components of the cart;at least two lid supports positioned between the at least two side tables and a grill bowl to support a grill lid in an open position, wherein the grill lid is supported between the at least two lid supports and a part of each side table when the grill lid is in the open position. 2. The cart of claim 1, further comprising a second cross-member. 3. The cart of claim 1, wherein the union member includes two substantially U-shaped channels for securing the upper frame and lower frame, the U-shaped channels providing resistance to movement of the upper frame and the lower frame. 4. The cart of claim 3, wherein the union member resists rotation of the upper frame and the lower frame about at least two points of each frame. 5. A cart comprising: a first union member, wherein the first union member has at least two internal channels;wherein the first union member comprises at least one protrusion for engaging with at least one depression in an upper frame or a lower frame, the upper frame and lower frame forming a first frame assembly;a second union member;a second upper frame and a second lower frame rigidly connected together by the second union member, the connected second upper frame and second lower frame forming a second frame assembly; each upper frame comprises a tube that is substantially “U” shaped, and wherein the union members are attached to the upper frames at a point substantially equidistant from the ends of the “U” shaped tubes;at least one cross-member comprising a substantially rigid table connected to the upper frames of the first frame assembly and the second frame assembly;at least two side tables rigidly connected to an upper portion of the first frame assembly and an upper portion of the second frame assembly, wherein the at least two side tables comprise structural components of the cart; andat least two lid supports positioned between the at least two side tables and a grill bowl to support an edge of a grill lid in an open position, wherein the grill lid is supported between the at least two lid supports and a part of each side table when the grill lid is in the open position. 6. The cart of claim 5, wherein the at least two lid supports are attached to the grill bowl. 7. A cart comprising: a first union member;an upper frame and a lower frame rigidly connected together by the first union member, the connected upper frame and lower frame forming a first frame assembly;at least one cross-member extending between the first frame assembly and a second frame assembly;a second union member;a second upper frame and a second lower frame rigidly connected together by the second union member, the connected upper frame and lower frame forming the second frame assembly;wherein the first and the second union members comprise two halves capable of being joined together to connect the associated upper frame and lower frame, and wherein each union member comprises at least two protrusions, each protrusion engaging with an associated depression in the upper frame and the lower frame, and wherein each union member resists rotation of its associated upper frame and the lower frame about at least two points;wherein each upper frame and lower frame comprises a tube that is substantially “U” shaped, and wherein the union members are attached to the upper frames at a point substantially equidistant from the ends of the “U” shaped tubes;at least two substantially rigid side tables connected to the upper frames of the first frame assembly and the second frame assembly, the at least two substantially rigid side tables comprising the at least one cross-member, the at least two substantially rigid side tables further comprising structural components of the cart;at least two lid supports rigidly attached to a grill bowl and positioned between the at least two side tables and the grill bowl to support a grill lid in an open position, wherein the grill lid is supported between the at least two lid supports and a part of each side table when the grill lid is in the open position.
