Description

[0001] The invention relates to a collapsible grilling device, consisting of a support frame and a grill grate held by the support frame, wherein the support frame is formed from several plate-shaped walls which are connected to each other by detachable plug connections. Thus, by releasing these plug connections, the grilling device can be converted into a transport and storage state in which the plate-shaped walls and the grill grate are stacked on top of each other to form a flat stack.

[0002] Such collapsible grills are used for mobile and portable purposes because they are quick and easy to assemble and disassemble. Their individual parts can be easily connected, preferably without tools, to create a stable grill. At the same time, the individual parts can also be easily separated for storage and / or transport, for example, in a relatively flat stack. Such a portable grill is known from CH 709799 A2. The portable grill comprises four side walls, a fifth side wall designed as a base, a grill grate for placing the food to be grilled, and a charcoal grate for placing charcoal, which, when lit, serves as a heat source. The four side walls are positively connected to each other by means of a plug-in connection, with the grill grate itself positively connected to two parallel side walls.The portable grill can be easily disassembled into flat parts, making it ideal for outdoor activities, especially camping or hiking. It can also be stored compactly, for example, in a backpack.

[0003] A disadvantage of this or similar well-known grilling devices is that they are fueled by charcoal, which is placed on a charcoal grate to provide the necessary heat for grilling. This means that users of such portable grills must carry a supply of charcoal when hiking. This reduces storage space in their backpack and unnecessarily increases the weight they have to carry. Furthermore, charcoal has the disadvantage of producing an open flame during grilling. Especially in dry areas, sparks from the charcoal can easily start fires. Operating such a portable grill can then become quite dangerous for the user if the dry environment around the grill catches fire.Furthermore, in certain areas it may be generally prohibited to barbecue with an open fire, so portable charcoal-powered barbecue devices may not be used.

[0004] Therefore, the object of the invention is to provide a compact, collapsible grilling device that can be stored in a space-saving manner and yet can be operated safely by a user.

[0005] According to the invention, this problem is solved by a collapsible grilling device according to independent claim 1. Advantageous embodiments of the grilling device are described in dependent claims 2-14.

[0006] It should be noted that the features listed individually in the claims can be combined with one another in any technically meaningful way and demonstrate further embodiments of the invention. The description further characterizes and specifies the invention, particularly in conjunction with the figures.

[0007] The grilling device according to the invention is collapsible. It consists of a support frame and a grill grate held by the support frame, the support frame being formed from several plate-shaped walls connected to each other by detachable plug connections. The plate-shaped walls preferably consist of sheets of stainless steel or another heat-resistant metal material. The thickness of the sheets used is between 1 and 8 mm, with the grill grate in particular being able to be thicker than the walls of the support frame.

[0008] The grilling device can be converted into a transport and storage state by releasing the plug connections, in which the plate-shaped walls and the grill grate are stacked on top of each other to form a flat stack. The plate-shaped walls can be completely flat without any protrusions or projections, resulting in a particularly flat stack when stacked. However, walls with minor protrusions or projections are also considered plate-shaped walls within the meaning of this invention. For example, it can be provided that in such a stack of individual parts, a projection in one wall engages in a recess in the adjacent wall. Slightly angled plates are also considered plate-shaped walls within the meaning of the invention. For example, such an angle can be on the order of approximately 160° to 179°. Furthermore, sheets angled in opposite directions can also be used.

[0009] However, what is essential for the invention is that the individual parts of the collapsible grill device, when placed on top of each other, result in a flat stack whose height is many times smaller than its dimensions in the other directions.

[0010] According to the invention, a collapsible grill with a support frame thus formed has at least two opposing bearing elements in which a heating device powered by a flammable gas is detachably held. The invention thus combines the advantages of a collapsible grill with a fluid-operated heating device such as a gas burner. However, a conventional gas burner is not simply placed under a grill grate, as might be the case with known collapsible grills. Rather, special bearing elements are provided on the support frame of the grill in which a heating device powered by a flammable fluid is detachably held. In this way, the heating device is held relative to the support frame, which ensures safety during operation of the grill.

[0011] At the same time, the heating element can be detached from the support frame, preferably without having to release any separate fasteners. Preferably, the heating element can therefore be detached without tools. In particular, the heating element is not screwed, riveted, or even welded on, but rather, as part of the collapsible grill, can simply be detached from the support frame. For this purpose, for example, positive-locking plug connections are suitable, which can, however, be released again by simple pulling and / or twisting movements. The heating element can also be removed in this way and stored in a stack of individual parts.

[0012] This inventive design of a grilling device offers several advantages, particularly for outdoor activities such as hiking or camping. All components of the grilling device can be easily, compactly, and safely stored and transported by a single user, for example, in their hiking gear. Furthermore, it eliminates the need to carry charcoal in the hiking pack, which would otherwise be required for numerous grilling sessions. When using the inventive grilling device, only a reservoir containing the combustible gas in liquid form needs to be carried. This reservoir can be stored in a space-saving manner in the hiking pack.

[0013] The problem of safely disposing of used charcoal also does not arise. Furthermore, the grill can also be used in areas where open fires with wood or charcoal are prohibited.

[0014] A further advantage of the grilling device according to the invention is that user safety during the grilling process is significantly improved. Uncontrolled sparks, such as those that can occur with burning charcoal, can be advantageously prevented by using the heating element, which is operated with the flammable fluid. In a dangerous situation, the user can immediately contain a flame by turning off the gas supply and thus minimize or even prevent the risk of fire.

[0015] Furthermore, mounting the heating element on the grill's support frame ensures that the gas flow direction remains essentially constant and flows directly towards the grill grate. This allows the food to be positioned precisely over the heat source, resulting in even cooking and heating, just like with conventional gas grills.

[0016] According to the invention, the mobile grilling device is therefore a cooking, grilling, and / or baking station that is easy to assemble and disassemble, and is particularly suitable for camping or hiking trips. Individual parts of the mobile grilling device can be assembled and disassembled with minimal effort. The individual parts are compact and stable components that can be stored in a space-saving manner, for example, in a backpack or bag. The user can assemble and disassemble the individual parts in just a few minutes, and preferably, no additional tools are required for assembly and disassembly because the grilling device does not use screws, for example.

[0017] In a preferred embodiment of the invention, the heating element is designed as a tubular burner rod with multiple outlet openings for the flow of flammable gas. The outlet openings are, for example, spaced apart from one another in one or more rows and preferably directed towards the grill grate to ensure the desired uniform heating of the food being grilled. Such a burner rod has the advantage of being easy to handle and attachable to bearing elements on the support frame of the grill. Furthermore, it can also be easily stored within a stack of individual grill components.

[0018] The heating device has a connection for a storage container of flammable gas in a liquid state. Specifically, a pressure regulator is provided between the heating device and this storage container. If a tubular burner rod is used as the heating device, it can have a connection at one end for a storage container of flammable gas in a liquid state, while the opposite end is gas-tight. Flammable gas flows into the burner rod through a gas inlet opening on the connection end and exits through several holes, where it can be ignited. The gas-tight end of the burner rod can be sealed, for example, by welding, bonding, or a crimp seam.

[0019] The connection for a storage tank containing flammable gas is preferably located on the outside of the support frame, so that it is accessible from the outside when the heating unit is installed. It is thus largely shielded from the heat of the heating unit. If a storage tank is connected to the heating unit via a hose, this, along with a pressure regulator, is located outside the support frame. The storage tank containing the flammable gas can therefore be positioned at a sufficiently safe distance from the flames of the heating unit, preferably using a flexible hose, for example made of stainless steel.

[0020] The bearing elements for holding the heating element can be designed in various ways. For example, they can be supports, locking devices, recesses, etc. Furthermore, the bearing elements are either designed so that the heating element can be attached to the support frame after the frame has been fully assembled. In an alternative embodiment, the insertion of the heating element is integrated as a step in the assembly of the grill. In a preferred embodiment of the invention, at least one bearing element is formed by an opening in the support frame into which a section of the heating element is inserted with clearance. This allows the heating element to be easily inserted into and removed from the opening. This is particularly advantageous for heating elements in the form of fuel rods that are pushed through an opening.Preferably, both bearing elements are designed as opposing openings into which the heating device is inserted with clearance.

[0021] To increase the safety of the grill, it is preferably provided that movement of the heating element in the direction between the two bearing elements is limited by at least one locking element on the heating element. This prevents the heating element from being unintentionally pulled or pushed out of the support frame. Such a locking element can also be designed in various ways. It should be designed so that, when the heating element is installed, it limits its movement in the direction between the two bearing elements; that is, a slight degree of movement may optionally be permitted. However, to remove the heating element, the locking element can be overcome by simple pulling and / or twisting movements of the heating element.

[0022] For example, external or internal locking elements can be used. An external locking element is located on the outside of the support frame, while an internal locking element is located on the inside of the support frame. An opening within the support frame can accommodate a section of the heating element in such a way that it is held in place by positive locking when the grill is in operation. This positive locking can be released for disassembly of the grill by simple pulling and / or twisting movements of the heating element.

[0023] In one embodiment of the invention, a locking element used for this purpose is formed by a mounting section that projects from the heating element at an angle α to its longitudinal axis and has a height H in this direction that is greater than the height h of the opening of a bearing element. This refers to the operating state of the grill device, in which it is positioned on a substantially horizontal plane. The mounting section projects, in particular, at an angle α of approximately 90° to the longitudinal axis of the heating element. If, for example, a horizontally extending slot with a height h is used as the opening, an outer locking element can have such a mounting section that is angled either downwards or upwards. The mounting section is located on the outside of the support frame and abuts this outside when it is pulled inwards with the heating element, since it does not fit through the slot.

[0024] To mount the heating element to the support frame using this angled mounting section, the heating element is tilted slightly around the longitudinal axis of the slot in the support frame, allowing the mounting section to be inserted through the slot with a tilting motion. To remove the heating element, this movement is performed in reverse. The locking element therefore only restricts the movement of the heating element when it is in operation; however, this restriction can be easily released with simple pulling and / or twisting movements. This provides a locking mechanism for the heating element within the grill, which is nevertheless easy and intuitive to release without tools.

[0025] A locking element can also be formed by a widened projection whose width B is greater than the width b of the opening of a bearing element. Preferably, such a locking element is designed as an internal locking element on the inside of the support frame. This prevents the heating device from being pushed outwards through an opening. This is particularly advantageous with a tubular fuel rod, as it could otherwise be pushed unhindered through two opposing openings.

[0026] In one embodiment, an inner and an outer locking element are provided only at one end of the heating device, so that the heating device is limited against inward and outward movement in one opening. Locking elements can then be omitted at the opposite opening. If, for example, a tubular fuel rod is used as the heating device, one embodiment of the invention provides that a bearing element is designed as a horizontal slot in the support frame, through which a flattened, angled mounting section at the end of the fuel rod is guided to form an outer locking element. The described projection is also formed at this end of the fuel rod as an inner locking element. The opposite bearing element, on the other hand, is designed as a through-opening through which the other end of the fuel rod can be guided.

[0027] A slot as a bearing element, in combination with a flattened section at the end of a round fuel rod, where the flattened section is inserted through the slot, has the further advantage that the fuel rod can also be secured against rotation about its longitudinal axis. The dimensions of the flattened section and the slot are selected accordingly so that the flattened section can rotate as little as possible, or even not at all, within the slot about the longitudinal axis of the fuel rod. However, such anti-rotation protection in a bearing element can also be designed in other ways. For example, the fuel rod could have a completely or at least partially polygonal cross-section, which is secured against rotation about its longitudinal axis in a correspondingly shaped opening in the support frame.Preferably, a rotation protection device can be provided between the heating device and the support frame in at least one bearing element, which, however, can also be released again by simple pulling and / or turning movements.

[0028] To enable the installation of a heating element despite various types of locking mechanisms, the insertion of the heating element is preferably integrated as a step into the assembly of the grill. Which assembly step is advantageously performed depends essentially on the design of the support frame and the plug connections used to join the individual parts. In one embodiment of the invention, the support frame is formed by at least four side walls arranged at right angles to each other, which are connected to one another by detachable plug connections. Various types of plug connections can be used, and all plug connections can be of the same type. Different types of plug connections can also be combined.

[0029] It has proven advantageous if at least the detachable plug connections for the side walls are each formed by hook tabs that can be interlocked with a corresponding insertion slot by moving them towards the edges of the side walls to be joined. For example, if two vertically oriented side walls are to be joined together at their edges, these edges have hook-shaped hook tabs with opposing insertion slots. The hook tab and insertion slot are inserted into each other by moving them towards the edges and thus interlocked. The hook tabs can also be released from the insertion slots in the same way. In one embodiment of the invention, two downward-facing hook tabs are located on each of two opposing side walls, which can be inserted from above into insertion slots on the other two side walls.

[0030] Preferably, such hook tabs and insertion slots are located only on the upper edges of the side walls, while the side walls are connected to each other in the lower area by other types of plug connections. For example, a base section is located below the heating element, which is attached to the four side walls by detachable plug connections. Simpler connections are preferably chosen for these plug connections. In particular, each connection consists of a hook tab that engages in a simple slot in a side wall. Alternatively, it can be a simple tab that is inserted into a slot. This combination of different plug connections makes it possible to assemble the grill according to a specific design without having to force or even bend the walls or hook tabs together.This construction scheme can also incorporate the heating element. Once assembled, it results in an extremely stable and torsion-resistant grilling device.

[0031] A base section is preferably designed as an angled sheet metal piece to create a concave drip surface on which dripping material can collect. To improve the gas grilling function of the grilling device according to the invention, a flame guard can also be installed between the heating element and the grill grate. This flame guard is also preferably attached to the support frame by means of detachable plug connections, and its installation can also contribute to the torsional rigidity of the grilling device. The flame guard is preferably formed by a roof-shaped sheet metal piece that runs above the heating element between the two walls with the bearing elements. The flame guard has several openings through which flames can pass. This allows the heat to be distributed more effectively to the food being grilled on the grill grate.

[0032] Furthermore, in one embodiment, the side walls can form feet. This can be achieved by providing at least one indentation on the underside of at least two side walls. These indentations form feet, so that the grill does not rest on the ground with long, continuous edges, but rather with at least four feet with shorter edges. This increases the stability of the grill on uneven ground. This can be supplemented by an additional indentation in each of the feet. With these second indentation, the grill can then be placed on two transversely arranged branches. This also increases the stability of the grill, and branches are easy to find and therefore do not need to be carried separately.The grill can also be placed on a flat transport bag, in which the components of the grill can be transported in a flat stack.

[0033] Further advantages, special features and expedient further developments of the invention will become apparent from the dependent claims and the following presentation of preferred embodiments with reference to the illustrations.

[0034] The illustrations show: Fig. 1 an embodiment of a grilling device according to the invention in a perspective view, Fig. 2 the grilling device according to Fig. 1 in an exploded view, Fig. 3 a first side view of the grill device, Fig. 4 a second side view of the grilling device, Fig. 5 a longitudinal view of the grill device, Fig. 6. Supervision of a barbecue device, and Fig. 7 a step in the installation of a heating device.

[0035] The figures show an embodiment of a grilling device 10 according to the invention, which is particularly suitable for outdoor activities such as hiking or camping. The grilling device 10 shown in the present embodiment comprises a support frame and a grill grate 20 attached to the support frame. The support frame is formed by several plate-shaped walls, in particular by four side walls 11, 12, 13, and 14. This creates a cuboid support frame with an upper opening into which the grill grate 20 is inserted. Two shorter side walls 11 and 12 are connected to each other by two longer side walls 13 and 14. However, this configuration with two shorter and two longer side walls is not to be understood as limiting; the description also applies to configurations with side walls of equal length or other aspect ratios.

[0036] The underside of the grilling device 10 is closed off by a base section 15, which is connected to all side walls 11, 12 and 13, 14. The base section 15 is also plate-shaped, but has an angled shape, resulting in a concave groove that runs between the two shorter side walls 11 and 12. Thus, the base section 15 forms a drip groove, which is preferably closed.

[0037] Furthermore, the grill 10 includes a heating element 30 that is operated with a flammable gas. In this embodiment, the heating element 30 is designed as a burner rod with a round cross-section, which has several outlet openings for the flow of flammable gas, one of which is designated by reference numeral 34. These outlet openings 34 are arranged in a row along the length of the burner rod 30, and several such rows may be provided. However, the heating element 30 can also have a different shape. For example, it can also be designed as a cuboid or a flat plate with several outlet openings for the flow of gas.

[0038] The heating element 30 runs between the two shorter side walls 11 and 12 and is held in place by bearing elements on these walls. These bearing elements are formed by openings in the shorter side walls 11 and 12. One opening in side wall 11 is formed by a slot 50, while an opening in the opposite side wall 12 is formed by a circular recess 51. The tube of the fuel rod 30 has a flattened section 32 at one end, which is inserted into the slot 50. The flattened section 32 is formed, for example, by a crimp seam or a weld, which seals the tube of the fuel rod gas-tight at this end. The other end of the fuel rod 30 is inserted into the circular recess 51.At this end of the fuel rod 30 is also the connection for a storage container with flammable gas in liquid form, so that a gas inlet opening 31 is located at this end, through which gas can flow into the fuel rod 30 and subsequently escape through the outlet openings 34. The end with the flattened section 32, on the other hand, is gas-tight.

[0039] The gas inlet opening 31, and thus the connection for a storage container with gas in liquid form, is located in the assembled state on the outside of the support frame formed by the side walls, i.e., on the outside of the side wall 12. This is particularly evident from the view of the Fig. 1 to remove. The fuel rod 30 thus protrudes a certain length beyond the side wall 12.

[0040] A roof-shaped flame guard 40 is arranged above the heating element 30. The flame guard is designed in a manner similar to that found on conventional gas grills. In particular, it has several flame openings 41, which are spaced apart from one another in two lateral rows.

[0041] The two longer side walls 13 and 14 each have a central indentation at their lower edges, through which two support feet 16, 17 and 18, 19 are formed. Additionally, a further, smaller indentation is formed in the lower edges of each of these support feet 16, 17, 18, 19. These indentations allow the grill to optionally be placed on crosswise branches, as shown in the Fig. 1 is shown as a dashed line.

[0042] These various components of the grill are connected to one another by several detachable plug connections. The four side walls 11, 12, 13, 14 are connected to each other at their vertical edges by plug connections formed by hook-shaped tabs and insertion slots. These tabs are also referred to as hook tabs because they protrude from the side walls like hooks. For example, side wall 11 has one hook tab 70 and 71 on each of its lateral edges, while the opposite side wall 12 has two hook tabs 72 and 73 on its lateral edges. These hook tabs are located in the upper area of ​​side walls 11 and 12, so that they can be inserted from above into corresponding slots in the other two side walls 13 and 14. Side wall 13 has two such insertion slots 91 and 92, while the opposite side wall 14 has two insertion slots 93 and 94.

[0043] The base section 15 is connected to the side walls 11, 13 and 14 by further plug connections. In the illustrated embodiment, there is no plug connection to the side wall 12, since this side wall 12 is preferably mounted last and another plug connection in this area would make it more difficult to insert the hook tabs 7, 73 from above into the insertion slots 92, 94.

[0044] The base section 15 has four tabs 80, 81, 82, and 83 that can be inserted into corresponding slots 60, 61, 62, 63 in the side walls 13 and 14. These tabs 80, 81, 82, 83 are also hook-shaped, with the hooks projecting towards the side wall 11. When the tabs 80, 81, 82, 83 are inserted into the slots 60, 61, 62, 63, the base section 15 is therefore slightly pressed towards the side wall 11 to create an interlocking connection. On one side of the base section 15 facing the side wall 11, two further tabs 84 and 85 protrude. These are formed by simple indentations without a hook function. They are therefore simply inserted into corresponding slots 64 and 65 in the side wall 11 without being hooked in place. The tabs 84 and 85 simply rest in the slots 64 and 65, so that these slots 64 and 65 can also be described as support slots.

[0045] Further support slots 66, 67, 68 and 69 are provided in the side wall 11 and the side wall 12 to hold the flame cover 40. For this purpose, the flame cover 40 has two simple tabs 42, 43 and 44, 45 at each of its ends, which are inserted into the support slots 66, 67, 68 and 69 without interlocking. Due to the angled roof shape of the flame cover 40, the tabs 42, 43, 44, 45 and thus the support slots 66, 67, 68, 69 are inclined.

[0046] The grill grate 20 is also connected to the four side walls 11, 12, 13, 14 via tabs and receptacles. For this purpose, the grill grate 20 has four support teeth 21, 22, 23, and 24 projecting from its sides. These can be inserted from above into correspondingly shaped receptacles on the side walls, which are open at the top. These receptacles 26, 27, 28, and 29 are located, for example, on the upper edges of the longer side walls 13 and 14, and their cross-section widens towards the top. Additionally, another projecting prong 25 is formed on the grill grate 20, which is inserted into a further support slot 90 on the side wall 12.

[0047] In the Fig. In the state shown in Figure 1, the grilling device 10 is fully assembled and ready for grilling food on the grill grate 20. For this purpose, a reservoir containing flammable gas in liquid form is connected to the burner rod 30, which may also include the installation of pressure regulators, pressure valves, hoses, etc. The grilling device 10 is stable, very torsionally rigid, and safe to handle. In particular, the burner rod 30 is secured against movement within the openings 50 and 51, as can be seen from the Fig. 7 will be described.

[0048] To assemble the grill device 10 from its various individual parts into the state of Fig. To relocate 1, a predetermined assembly pattern is preferably followed. In particular, the two longer side walls 13 and 14 are first connected to the shorter side wall 11 via the described plug connections. The two side walls 13, 14 are slightly spread apart to connect the base section to the three side walls 11, 13, 14 via the plug connections also described. Furthermore, the end of the fuel rod 30 with the gas inlet opening 31 is pushed from the inside through the opening 51 in the side wall 12. In this state, the other end of the fuel rod 30 with the flattened section 32 is pushed through the slot 50 in the side wall 11. For this purpose, the fuel rod 30 is tilted slightly upwards about the longitudinal axis of the slot 50 to allow an angled fastening section 33 on the flattened section 32 to be pushed through the slot 50. This process is indicated by an arrow in Fig. Figure 7 shows that since the burner rod 30 is inserted into the round opening 51 with some play, the side wall 12 can be easily tilted outwards to slide the flame guard 40 with its tabs 42, 43, 44, 45 into the support slots 66, 67, 68, 69. The side wall 12 is pressed towards the opposite side wall 11 to hold the flame guard 40 between the two side walls 11, 12. In this position, the side wall 12 can be lowered to insert the hook tabs 72 and 73 from above into the insertion slots 92 and 94 of the two side walls 13, 14. The grill grate 20 is then inserted at an angle with its prong 25 into the slot 90 and lowered. The supporting teeth 21, 22, 23, 24 can rest in the receptacles 26, 27, 28, 29. As can be seen particularly from the side view of the Fig. As can be seen in Figure 5, the support teeth 21, 22, 23, and 24 each engage with a projection in the lower area of ​​a side wall of the respective receptacle 26, 27, 28, 29 when the grill grate 20 is inserted with its locking tooth 25 towards the slot 90. Thus, the grill grate 20 can no longer be easily lifted upwards out of the receptacles 26, 27, 28, 29. Instead, the grill grate 20 must first be pulled out of the slot 90 with its locking tooth 25 to release the engagement with the projection of the respective receptacle. Furthermore, a recess may be provided on the bottom of a receptacle 26, 27, 28, 29 into which a support tooth 21, 22, 23, and 24 lowers under a projection when inserted (see, for example, the right receptacle 27 in Figure 5). Fig. 5) The grill grate 20 is thus secured against horizontal movement and, given its sufficient weight, is held in the recess by gravity. This securing mechanism is released when the grill grate 20 is lifted out of the slot 90 and the receptacles 26, 27, 28, 29 by a pulling and tilting motion.

[0049] In this final state, the fuel rod 30 is secured against movement between the two openings 50, 51, since at least one locking element, but preferably two locking elements, act on the slot 50 (see Fig. 7) A first locking element is formed by the fastening section 33, which projects at an angle α from the longitudinal axis of the burner rod 30. It projects upwards and has a height H in this direction that is greater than the height h of the slot 50. The fastening section 33 lies on the outside of the side wall 11 and, by means of a positive fit, prevents the burner rod 30 from moving towards the opposite side wall 12, since the fastening section cannot pass through the slot 50 in this position. Therefore, the burner rod 30 cannot be unintentionally pulled out of the grill through the opening 51. For example, if someone unintentionally pulls on a hose and / or the gas reservoir, this does not lead to a dangerous situation in which a burner rod 30 is pulled outwards with flames. Rather, the burner rod 30 is always protected and securely housed inside the grill.

[0050] However, an additional locking element prevents the burner rod 30 from being inserted too far through the grilling device. For this purpose, a widened projection 35 is provided on the end flattened section 32 of the burner rod 30. This projection 35 has a width B that is greater than the width b of the slot 50 in the side wall 11. The projection 35 thus abuts the inside of the side wall 11 when the burner rod 30 is pushed in this direction. The flattened section 32 in the slot 50 also provides anti-rotation protection.

[0051] The locking elements 33, 35 secure the burner rod 30 in the grilling device 10. This locking mechanism can be released, however, by simple pulling and / or twisting movements when the grilling device is disassembled. The assembly steps described above are carried out in reverse order, starting with the side panel 12 being pulled upwards out of the insertion slots 92, 94, etc. The burner rod 30 is released from the slot 50 by pulling / tilting it upwards. Subsequently, all other connections can be disconnected and the burner rod removed from the side panel 12. Finally, the entire grilling device is available in several flat individual parts, which can be stacked on top of each other for transport, preferably in a bag or backpack.

[0052] For example, from the Fig.As can be seen in Figure 3, there is an opening in the area of ​​slot 50. The heating device can be ignited through this opening with a flame or spark source.
