ABSTRACT:
TECHNICAL FIELD
The present invention relates generally to barbeque grill carts, and, more particularly to an end cap bar which attaches to the frame members of a barbeque grill cart.
BACKGROUND OF THE INVENTION
Barbeque grills have become very popular as outdoor cooking devices. Typical grills, particularly gas grills, are supported by a barbeque grill cart. These carts are formed using a plurality of frame members and/or sheet metal panels. The frame members are often tubular metal supports aligned in a grid-like structure of vertical and horizontal bars. Thus, cross bars are mounted to support parallel frame members.
The ends of the frame members are usually closed with conventional plastic end caps. One of the problems with such grill carts is the difficulty for the purchaser to assemble side accessories. Such assembly may involve following detailed instructions and packaging of numerous parts. Attachments to such grill carts are generally added using additional hardware for mountings, adding expense and extra parts to the construction of such a cart. It is preferable to keep parts to a minimum in order to allow for compact packaging for shipping. There is, therefore, a need for a barbeque grill cart having a convenient way of mounting an end bar which closes off the ends of the frame members and provides support to the cart structure. Furthermore, there is a need for an end bar assembly which provides for convenient addition of accessories.
SUMMARY OF THE INVENTION
According to the present invention, a new end bar has been developed to attach to the end of a barbeque grill cart by mating receiver and projection securement between the end bar and the cart frame members. This end bar provides a convenient way to close the ends of the frame members of the cart while providing support and stability to the structure of the cart frame. The end bar serves to also enable the elimination of a support bar in the frame of the cart, thus reducing the number of parts in the construction. The end bar further provides a convenient manner of adding a handle or decorative end to the cart without the addition of further mounting hardware.
According to one aspect of the invention, the end bar is provided with a pivot port adapted to receive a pivot pin or pivot assembly of a pivotally mounted shelf. Such a shelf could optionally be one described in copending, commonly assigned U.S. application Ser. No. 09/374,821 (filed using Application Identifier 217 P708) filed Aug. 13, 1999, which is hereby incorporated by reference in its entirety.
According to another aspect of the invention, the end bar is spaced from the cart frame and formed to provide a handle, such as one which could be used to move the cart.
According to a further aspect of the invention, the end bar is provided with utensil holders on an outer side of the end bar for conveniently hanging barbeque utensils.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following drawings.
