1. Field of Invention
The present invention relates to a portable barbecue grill and, more particularly, to a portable barbecue grill with collapsible legs.
2. Related Prior Art
There are various barbecue grills. Some of them are large and equipped with wheels for movement. Some others of them are small and portable without the use of wheels. In use, the portable barbecue grills are generally laid on the ground, with people sitting on short stools or chairs around them.
Some of the portable barbecue grills are equipped with short and non-collapsible legs. The short legs make it easy to transport the portable barbecue grills. However, short legs lift the barbecue grills to insufficient height, and hence render it tiresome to cook. Long legs are used to lift the portable barbecue grills to adequate height to render it less tiresome to cook. However, the long legs render it difficult to store the portable barbecue grills.
Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art.
It is the primary objective of the present invention to provide a comfortable-to-use and convenient barbecue grill.
To achieve the foregoing objective, the portable barbecue grill includes a bowl, four legs and four connecting units each for connecting a corresponding one of the legs to the bowl in a collapsible manner.
In an aspect, each of the legs includes an aperture. Each of the connecting units includes a pin for insertion in the aperture of a corresponding one of the legs to keep the legs in an extended position.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:
Referring to
The four legs 12 are classified into two left legs 12 and two right legs 12. A bar 16 is used to interconnect the left legs 12. Thus, the left legs 12 are operable as a whole and it is therefore convenient to maneuver them. Moreover, buckling of the left legs 12 from each other is avoided and the left legs 12 are hence reliable. Similarly, another bar 16 is used to interconnect the right legs 12. Each of the legs 12 includes a large aperture 18 and a small aperture 20.
Each of the connecting units 14 includes a major supporting element 22, a minor supporting element 24, a pin 26 and a spring 28. The major supporting element 22 includes a middle transverse portion, two lateral transverse portions, and two longitudinal portions each extending to the middle transverse portion from a corresponding one of the lateral transverse portions. The middle transverse portion includes a large aperture 30 corresponding to the large aperture 18 and a small aperture 32 corresponding to the smaller aperture 20. Each of the lateral transverse portions includes an aperture 34. Each of the longitudinal portions includes an aperture 36. The spring 28 is a helical spring.
The minor supporting element 24 includes a transverse portion formed between two longitudinal portions. The transverse portion of the minor supporting element 24 includes an aperture 38. Each of the longitudinal portions of the minor supporting element 24 includes an aperture 40.
The pin 26 includes an annular rib 42 extending between two portions. The portions of the pin 26 may be made of a same diameter or different diameters. The pin 26 is formed with a rounded end 44.
Referring to
The minor supporting element 24 is secured to the major supporting element 22 by inserting a fastener such as rivet or a screw (not shown) in the aperture 40 of each longitudinal portion of the minor supporting element 24 and the aperture 36 of a corresponding longitudinal portion of the major supporting element 22. The first portion of the pin 26 is inserted in the aperture 32. The second portion of the pin 26 is inserted in the spring 28. The spring 28 is compressed between the annular rib 42 and the transverse portion of the minor supporting element 24 to bias the rounded end 44 of the pin 26 toward the leg 12.
Referring to
The rounded end 44 of the pin 26 of each connecting unit 14 is pushed out of the small aperture 20 of the corresponding leg 12. Then, the legs 12 are pivoted into a collapsed position referring to
The present invention has been described via the detailed 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. For example, there may be only two connecting units 14, one for one of the left legs 12, which are interconnected by a bar 16, and the other for one of the right legs 12, which are interconnected by another bar 16. Therefore, the preferred embodiment shall not limit the scope of the present invention defined in the claims.
