DESCRIPTION OF FIGURES

[0058] FIG. 1 shows one of the possible embodiments for a barbecue spit. There are enlarged images D and E which show structural specifics of a barbecue spit. FIG. 1 shows that a barbecue spit structurally consists of a bearing rod (1) enforced with the frames (2). Outer end edges of a rod are supporting elements however they can be used for impaling food. The parts of bearing rod can be supplemented with additional bearing intervals. The holding grill nets (3) are fixed within a frame (2).

[0059] FIG. 2 depicts one possible embodiment of a barbecue spit (1) with two reinforcing frames (2). The presented design can be performed as a solid and demountable structure. To facilitate the operation each frame has an additional cross-connection element, which is optional but useful, especially with a barbecue spit of a large length.

[0060] FIG. 3 shows a preferred embodiment of the fastening elements for the grill nets. The fastening elements hold a grill net within the frame by pressing of the meshed elements of a grill net to a frame and by additional locking of meshed elements within a frame. This fastening elements are configured as W-shaped brackets (4) (hereinafterthe bracket) with a hole (5) in a central end. With its inner part, a bracket (4) holds one part of the grill net, while its central end passes through wires or rods of a grill net. Then a part of a grill net (3) with a bracket is connected to a reinforcing frame (2) so that the side ends of this bracket embrace this frame. The other part of a grill net is mounted onto the other side of a reinforcing frame (2) so that it passes between the side ends of a bracket whereas a central end of a bracket passed through its wires or rods. A pin (6) is inserted into a hole made in a central end, which projects over a grill net. The parts of a grill net (3) fixed by means of such fastening elements are securely fixed onto a frame. To ensure reliable fastening, diameter of a bracket hole should correspond to diameter of a pin (6). Also it is preferable that a length and a shape of a pin are the same as shown in FIG. 3 and FIG. 3a. According to a preferred embodiment, a bracket is configured so as to adjust the degree of pressure and, sometimes, the inner volume of a rack formed by the meshed elements of a grill net. To ensure this, a number of holes (5) are made in a central end of a bracket (4). For example, if a degree of pressure is insufficient, it can be increased by inserting a pin (6) in the next suitable hole (5). Even if a degree of pressure is appropriate it can be increased to reduce the inner volume inside the rack to a certain degree by parallel reducing the possibility of moving for food inside.

[0061] Another advantage of configuring fasteners as a W-shaped bracket (4) with a pin (5) is that with a series of holes made in a central end of a bracket (4) we can not only reduce the inner volume, which is determined by position of meshed elements of a grill net and the degree of pressing them together, but also to increase volume to a certain degree if necessary. For this purpose it is proposed to use a bracket (4) with elongated ends and, consequently, with more holes (5), made in its central projection. In the event when it is necessary to prepare a meal which size does not allow to fix it inside a rack, formed by meshed elements of a grill net (3), fastening is done by inserting a pin (6) in the next suitable hole (5) of elongated central projection of a bracket (4). In this case, a sufficient degree of pressing a meal to the elements of a grill net (3) is ensured and a meal is fixed with a help of the brackets (4) with the pins (6). Thus it is possible to achieve the required degree of pressing a meal to the meshed elements of the grill net (3), to form an acceptable gap between the elements of the grid (3) and a frame (2), and achieve even greater versatility of a barbecue spit (1) with respect to a variety of products that can be cooked simultaneously in it.

[0062] FIG. 3a shows one of the embodiments for a pin which is considered to be the most advantageous for functional design of bracket connection. A pin (6) is made of any suitable material. One of its ends is narrowed to facilitate its entering into a bracket hole. For this purpose this pin end can be bended to a certain degree. The other end of a pin is bended to make manipulations with pin more easy while locking and unlocking. This bend may be made by a simple bending of a pin end at a certain angle or it is made in a shape of a hook or any other suitable shape. In a FIG. 3a this bend is made in a shape of an eye. This embodiment is the most convenient and safe. It facilitates maintenance and transportation of pins. Pins can be kept in suspended state. A connection can be unlocked quickly and safely due to the easer removal of a pin by means of hooking an eye with special and available equipment.

[0063] FIG. 3b shows in more details configuration of a W-shaped bracket (4) for a preferred embodiment of grill nets fastening. Similar to a pin, a bracket can be made of any suitable material. There are several holes (5) in its central end to provide specified degree of pressure of meshed elements and frame to each other and/or ensure specified volume of rack formed by spit's meshed elements as it was described above. FIG. 3b shows two holes (5) in a central end, but it is clear that the number of holes and the length of a bracket end can be either, depending on the requirements of real situations. In addition to the direct functioning as a connection element a bracket can be used as a support for the grill net in which the dish can be offered to the table. In this case it can be further configured using various design techniques. Of course, it must be ensured that all technical and operational characteristics of a bracket are preserved.

[0064] According to the alternative embodiment, the fastening can be configured with the help of U-shaped bracket. The idea of fastening is the same as for a W-shaped bracket with the only difference that this bracket has no central end and a pin is inserted not in the longitudinal direction with relation to a spitinto a hole in a central end as in the previous embodimentbut in a transverse directionin a symmetrical pair of holes made in side ends of an U-shaped bracket. At the same time the idea of adjusting a degree of pressure for grill net elements is the same. In addition this embodiment of fastening elements is more advantageous because there is no need to configure an element for securing a grill net on a frame. This causes obvious advantages to operate a barbecue spit such as convenient washing, cleaning, repairing, storing, etc.

[0065] Another advantage of this type of a lock is that it can be easily disassembled, which is important when dealing with hot equipment. A person can demount the device even without using his hands, for example, with a help of a key which is inserted into eye of pin to pull it out. In addition, during disassembling all cooked meals remain on the grill net and can be served directly on grill net and put on a support to the customers, which is especially important for keeping shape of delicate products and/or for creating a special mood of serving procedure. Especially it can be demonstrated in the case of using securing W-shaped or U-shaped brackets as supports.

[0066] FIG. 4 shows a part of a holding grill net (3) separated from a frame (2) of a spit (1) with an enlarged image F. The proposed shape is most preferable for the present invention because it allows to adjust the volume of the internal space in the rack by fixing a bended side of a grill net both inside and outside the frame.

[0067] FIG. 5 shows one possible embodiment for spit's ends which are configured as sharp elements of assembling pair for screw/bolt or pin connections and can be used for direct impaling of meal products subject to cooking.

[0068] The present device operates as follows. The products that are subject to cooking are placed on one of the meshed parts of a grill net that occupies the lower position on the frame of assembled spit or on the separate meshed part of a grill net if it is not rigidly connected with a frame. Products to be grilled on a spit are strung on a bearing rod or its parts that will be connected with the frames or its other parts. The parts of a holding grill net that need to be fixed are secured on the frame to form a closed rack for food products. A position of a bended part of a grill net to be connected to the frameoutward or inward positionis determined on the assumption that if this will prevent the free movement of products in the rack formed by a grill net or not. This condition is quite advantageous. Additional adjustment of volume formed by a grill net is possible by means of locks, which allow to adjust the degree of pressure of the parts of a grill net to the frame. The parts of a holding grill net are fixed in a manner appropriate to a special case. A bracket connection for the parts of a grill net that is chosen as a preferred embodiment of the present invention but not limiting hereto, is disclosed in the description to the FIG. 3.

[0069] An assembled spit is moved to a heat source. An open fire or a hot charcoal flame can be used as a source of heat in a barbecue for example as disclosed in patent UA 83718 U. After cooking, in one case, a spit is moved from heat source and put in the side tray, an upper part of a holding grill net is removed and the cooked product is taken out. In other case, for example, when we deal with the removable frames, the upper fastening elements of a grill net are removed after placing an accessory like the spade under the lower part of a grill net. In this case the cooked meal remains in the lower part of a grill net and can be served in it for eating or put into other containers or dishes.

[0070] The claimed invention can be illustrated with the following examples. Example 1. A barbecue spit with a rack, main embodiment.

[0071] A barbecue spit consists of a bearing rod (1) with two rectangular frames (2). A length of a spit is 2.5 meters. The design of a barbecue spit provides two disassembling frames in a rectangular shape made of metal wire of square cross-section with a thickness of 7 mm and a length of 1.2 m, width of 10 cm connected together with a segment of metal rod of the same cross-section and a length of 5 cm. On the outer edges of the frame there are also the segments of sharpened rod with a length of 10 cm. A frame may be provided with a transverse cross-bar which helps to suspend a spit or to place it on the supporting items of a barbecue or the supports installed on the ground that facilitates spit's assembling and disassembling, or to eliminate other unforeseen situations.

[0072] Grill net parts are connected to the frames and due to outward bended structure form a rack for food to be cooked. The grill nets are made of a thin wire with cross-section of 1 and 2 mm. The grill net rods intersect at right angles and are fixed by welding. The preferable width of the grill net is 5-10 mm less than the width of the outer frame width, that helps to regulate the space between the grill nets.

[0073] The space between the parts of grill nets is adjusted to fit different sizes of products placed inside in the following way. According to the first variant, a bended part of a grill net is put outside, while according to the second variant one of a bended parts of the grill net is placed inside a rack to reduce the space between the grill nets.

[0074] The grill nets are fixed freely on a frame and after products are placed between them the grill nets are fixed with the brackets with a pin or with a hook which pull together two grill nets with some tension. Due to such tension the grill nets are secured to the frame.

[0075] A barbecue spit in an assembled state and filled with products is placed on a barbecue with glowing coals. A grill operator looks after the degree of heating and roasting of a product by changing the position of the grill to 90. As the product is heated, the number of rotations of a spit should increase gradually for even roasting and acquiring attractive brown surface.

[0076] A square cross-section of a bearing rod eliminates the need for monotonous turning of a spit and/or the need to apply any mechanical means for fixing it in a specified position when some side of product needs additional roasting over a heat. When a grill operator finds that the product is prepared, the parts of a grill net with prepared product are removed from a spit and are replaced with the new ones with a new product or the frames with grill nets are removed and replaced by new frames with grill nets with a new product, or they are replaced with a rod section with impaled products or the whole spit is taken to a separate tray and is used according to the situation.

[0077] Example 2. A barbecue spit, alternative embodiment. According to another embodiment of the invention a bearing rod (1) and a reinforcing frame (2) are configured the same way as in the example 1. It differs from the main embodiment only in that a grill net is solidly secured to the frame with one side that allows to open/close the other unsecured side. This side is fixed to the frame with the help of a bracket.

[0078] Another feature of the implementation is that a spit is equipped with the additional reading rod sections on its sides and inside for extra impaling of suitable product onto it. Further process of cooking and spit operation is similar to the one described in the Example 1.

[0079] Example 3. A spit, another alternative embodiment. According to a further embodiment, a bearing rod (1) and a reinforcing frame (2) are configured the same as in the Example 1, with the difference that a grill net is made of pieces of perforated sheet metal with the thickness of 1 mm.

[0080] The area of evenly spaced holes on a grill net configured this way covers more than 50% of the total area of the sheet material. The space between the parts of a grill net and the grill net fastening elements is adjusted in a similar way as described in the Example 1.

[0081] The invention has the following technical results: An extended barbecue spit with a grill net, designed according to this invention, ensures high cooking performance and versatility of food products to be cooked with its use;

[0082] The proposed device can be scaled to any size by serial connection of the frames and the bearing rods to each other; The device has a universal design, which is achieved by the possibility to connect the various elements between each other; frames of different shapes and capacities can be combined in one design, and in addition the traditional spit rods can be combined in one device.

[0083] Such design of a spit provides quick operation and low complexity of the process of placing products on the spit and removal of products and the possibility to use it in combination with effective means of fastening, including brackets with pins;

[0084] There is no need to keep a large number of small devices in the kitchen or kitchen area such as skewers, grills; the cooking process is more organized; A larger number of products can be grilled evenly without the need to involve special equipment for rotating or turning, work of a grill operator is much simplified. The device reduces the number of service staff per unit of manufactured products;

[0085] The number of spoiled ready-to-serve dishes due to human factor is reduced; The ready-to-serve dishes can be served to the consumers directly in spit elements, such as the grill nets; The invention ensures reliable fixation of products inside the rack meshes that prevents products from falling out and/or from uneven cooking;

[0086] The invention provides uniform roasting over an open fire of such products as fish meat, whole fish, seafood, vegetables and others; The invention provides possibility to rotate simultaneously a large number of small products for example 80 burger chops in less than a second while grilling; The device insures intensification and mobility of a cooking process without compromising quality. For example, a team of 6 people, under the supervision of an experienced cook, can deploy a food service unit within two hours and prepare a wide range of dishes, including at least four kinds of dishes (meat, vegetables, potatoes and bread products, such as khachapuri) and feed about two thousand people, and then close and remove a food service unit.
