Description:

BACKGROUND OF INVENTION

1. Field of Invention

The present invention relates to barbecue and, more particularly, to a barbecue cart that can easily be extended and collapsed, and can firmly be retained in the extended position, and can easily be carried in the collapsed position.

2. Related Prior Art

A barbecue party is an activity in which participants can easily fling themselves into and communicate with one another. Hence, barbecue parties are getting popular.

There have been various barbecuing devices, ranging from simple grids to full-functional barbecue carts, to satisfy different users' needs. Simple grids can easily be carried; however they are not suitable for large barbecue parties. Full-functional barbecue carts are suitable for large barbecue parties; however they cannot easily be carried since their wheels cannot smoothly roll on the lawn that is often bumpy. To take mobility and capacity into account, there are collapsible barbecue carts such as disclosed in U.S. Pat. Nos. 5,318,322 and 6,863,063. However, these collapsible barbecue carts include complicated structures or cannot firmly be retained in their extended positions.

The present invention is intended to obviate or at least alleviate the problems encountered in prior art.

SUMMARY OF INVENTION

It is the primary objective of the present invention to provide a collapsible barbecue cart that can easily be extended, collapsed and can firmly be retained in the extended collapsed.

To achieve the primary objective, the present invention provides a collapsible barbecue cart including a stove and a collapsible stand connected to the stove. The collapsible stand can be changed between an extended position and a collapsed position. A socket is secured to the stove. An insert is secured to the collapsible stand. The insert can be inserted in the socket as the collapsible stand is in the extended position.

Other objectives, advantages and features of the present invention will become apparent from the following description referring to the attached drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Referring to FIGS. 1 through 3, there is shown a collapsible barbecue cart according to the preferred embodiment of the present invention. The barbecue cart includes a stove 10 and a collapsible stand 20. The stove 10 will not be described in detail for being conventional.

The collapsible stand 20 includes a first pair of legs 21 and a second pair of legs 25. The legs 21 are connected to each other by three crossbars. Each of the legs 21 is pivotally connected to the stove 10 by a joint 11. Each of the legs 21 is pivotally connected to a related one of the legs 25. The collapsible stand 20 can be moved between an extended position shown in FIG. 4 and a collapsed position such as shown in FIG. 7.

The legs 25 are connected to each other by three crossbars of which the uppermost one is represented by “26.” An insert 27 is installed on the crossbar 26. The insert 27 defines a recess 28. A wheel 29 is connected to each of the legs 25.

A bracket 16 includes a first section and a second section extending from the first section at the right angle. The first section of the bracket 16 is secured to the bottom of the stove 10. The second section of the bracket 16 defines an aperture 160.

A socket 15 is secured to the first section of the bracket 16. The socket 15 defines an aperture 150. The socket 15 receives the insert 27 when the collapsible stand 20 is in the extended position.

Referring to FIG. 5, a latch 18 includes a first section and a second section with a diameter than that of the first section and that of the aperture 160. The first section of the latch 18 is inserted through the aperture 160. A ring 17 is connected to the first section of the latch 18 so that the latch 18 is retained on the second section of the bracket 16. An elastic element 19 is installed on the first section of the latch 18. The elastic element 19 is compressed between the second section of the bracket 16 and the second section of the latch 18. Biased by the elastic element 19, the second section of the latch 18 is retained in the aperture 150 and the recess 28. The insert 27 is retained in the socket 15 so that the collapsible stand 20 is firmly retained in the extended position shown in FIG. 4.

Referring to FIG. 6, the ring 17 is pulled, and the second section of the latch 18 is removed from the recess 28. The insert 27 is removed from the socket 15. Therefore, the collapsible stand 20 can be changed to the collapsed position shown in FIG. 7.

Referring to FIG. 8, the collapsible cart is in the collapsed position. A user holds one of the crossbars between the legs 21 while leaving the wheels 29 rolling on the ground. Thus, the user can easily carry the collapsible cart in the collapsed position.

The present invention has been described through the illustration of the preferred embodiment. Those skilled in the art can derive variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
