This invention is associated with the field of barbecue grills, which could carry out the grilling operation in a portable way so that it does not require to be stable in a place to utilize it.

Technical Problem and Objectives of the Invention

Grills have yet been operated such that they need to be deployed on the ground or table or required to be fixed on the wall. In either case, the grills must be stable for grilling and could not be movable during use. Thus, in order to address this problem, a portable grill was designed that no longer needs to be set up in a constant location for using it.

Describing the Status of Previous Knowledge and a History of Developments Progressions in Conjunction with the Claimed Invention

There are three types of grills, constituting a gas grill, an electric grill, and a charcoal grill. Any of these grills could be employed on the floor or table or fixed on the wall. Subsequently, the features of each of them will be elaborated.

Gas Grill

The gas grill is among the novel and convenient designs of this apparatus, which has been placed in the category of the most frequently used models of grills because of its easy use. Gas grill exploits two fuels, including natural gas (town gas) and liquefied petroleum gas. The most widespread application in this respect is liquefied petroleum gas (LPG), which could be utilized in places where there is no likelihood of using natural gas.

There are some advantages to using a gas grill. Due to enjoying these benefits, it is typically a suitable choice to use, containing:

• Ease of use

• Immediate setup of the grill • Short time in grilling (cooking barbecue)

• Eliminating the cost of purchasing coal and the healthy nature of this model relative to the charcoal grill

• Because of having cast-iron sheets on the flames, it causes the barbecue to be well-cooked thoroughly

Electric Grill

Electric grills precisely have a similar operation to the gas grill models; however, they use electricity as fuel instead of natural gas or liquefied petroleum gas (LPG).

Charcoal Grill

The charcoal grill is the most popular type of grill. Due to the smoky smell that gives to the kebab, this barbecue grill model has been very welcomed by many people.

In this way, shoulder straps are tied to the chassis. Shoulder straps are set on the shoulders of the operator, which have the capability to be tuned with respect to his/her height. Two loops (Fig. 6 No. 15) are embedded on the shoulder straps that could be employed for hanging tools and accessories. A chest brace (Fig. 6 No. 16) is sewn on these straps with a lock (Fig. 6 No. 17) for opening and closing, which has the ability to be tuned and avoids the slipping of the shoulder straps. The pelvic positioning belt (Fig. 7 No. 18) has two straps (Fig. 7 No. 19) on its sides. One end of the straps is pressed to the pelvic positioning belt and a loop (Fig. 7 No. 20) is sewn to the other end of each of the straps. The loops on each side are connected to a carabiner (or karabiner) (Fig. 7 No. 21). These carabiners are attached to the hoops (Fig. 4 No. 5) welded to the chassis. In this way, the pelvic positioning belt is attached to the chassis. A buckle (Fig. 7 No. 22) is sewn on each of the belts of the pelvic positioning belt, which is employed for the tuning of the pelvic positioning belt concerning the operator's height. This belt has the capability of tuning with regard to the size of the operator's waist. The chassis is fastened to the grill body (Fig. 8 No. 23) by bolts (Fig. 4 No. 7) and nuts (Fig. 4 No. 8). Some indentations (Fig. 8 No. 24) at the top of the grill body are embedded in various shapes and sizes so that equipment and accessories could be put in them and transported. A gas valve (Fig. 10 No. 34) is set on the right side of the grill body (Fig. 27), which has a handle (Fig. 10 No. 35) to control the rate of exhaust gas. The gas valve is connected to the L-shaped metal pipe (Fig. 10 No. 38) by a fastener (Fig. 10 No. 36) and bolts (Fig. 10 No. 37), and the gas valve inlet is made of the L-shaped metal pipe. An end of this L-shaped metal pipe (Fig. 10 No. 38) is blinded and the other end is welded with a nut (Fig. 10 No. 39) and the miniature plug nut coupling (the male part) (Fig. 10 No. 40) is screwed into it. The two connectors (Fig. 10 No. 41) are welded to an L-shaped metal pipe (Fig. 10 No. 38). These two connectors are attached to the body of the grill by bolts (Fig. 10 No. 42) and nuts (Fig. 10 No. 43). A nut (Fig. 10 No. 44) is welded on an L-shaped metal pipe (Fig. 10 No. 38). Besides, a hole is generated in the center of the nut on the pipe so that the gas can flow. Also, the pilot light (Fig. 10 No. 46) is connected to the nut (Fig. 10 No. 44) welded on the L-shaped metal pipe (Fig. 10 No. 38) by means of a nut (Fig. 10 No. 45), and thus gas goes to the pilot light.
