The two lateral sides of the push-cart are respectively pivotally mounted with a plurality of support frames, the height of the frame is lower than the width of the cart body and the bottom edge of the cart body, at the corner of the frame is mounted with a mounting tube having a horizontal tube body and a through hole is mounted at the wall of the mounting tube and an elastic peg is inserted, an engaging hole, corresponding to the elastic peg, is provided at the support frame such that when the frame is vertically extended from the bottom board of the cart body, the elastic peg will automatically engage with the engaging hole to lock the frame, and the releasing of the elastic peg will fold the frame and assemble below the cart body.
Description




BACKGROUND OF THE INVENTION




(a) Field of the Invention




The present invention relates to a barbeque (BBQ) push-cart, and in particular, a BBQ push cart having a plurality of retractable support frames mounted at the bottom of a cart body, allowing the frames to be kept under the cart body and/or extended when in use.




(b) Description of the Prior Art




Conventional BBQ stoves which fixed onto a fixed structure on the ground or support are normally too close to the ground, and very often, the prepared and barbecued food may not be hygienic enough as a result of pollution by the dust from the ground or the ashes from the burning charcoal. Besides, in a squatted position to grill food by a person is not comfortable. To overcome these drawbacks, high grilling net BBQ stove has been developed. However, this BBQ stove causes other problems, especially lacking a storing space to keep the BBQ stove when it is not in use. Other conventional BBQ stoves are designed but in operation, some tools are needed in order to put up the BBQ stove to work or to dissemble when it is not in use. In view of the above, it is a prime object to design an improved structure of a BBQ pushcart, which can mitigate the above drawbacks.




SUMMARY OF THE INVENTION




Accordingly, it is an object of the present invention to provide an improved structure of a BBQ push-cart, wherein a plurality of support frames are provided to the two lateral sides of the cart body and are pivotally mounted together with a mounting tube which can be folded and kept at the bottom of the cart body.




Yet another object of the present invention is to provide an improved structure of a BBQ push-cart, wherein the cart body is mounted with a grill oven having a grilling basin, and the sides of the basin are grooved, and a slit is formed to the groove to discharge residue in the course of barbequing.




A further object of the present invention is to provide an improved structure of a BBQ push-cart, wherein a stepped wall is formed at the two lateral wall of the basin for the horizontal mounting of a grilling net and a charcoal holding board at different height of the lateral wall, allowing independent discharging of ashes of the charcoal by first removing the grilling net and then slanting the charcoal holding board to discard the ashes.




A further object of the present invention is to provide an improved structure of a BBQ push-cat, wherein the collection of ashes and clearing of the cart body are simple, without turning the entire BBQ push-cart upside down as compared to the conventional BBQ stove.




The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.




Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
