Description

[0001] The present invention relates to a gas grill according to the preamble of claim 1.

[0002] A gas grill, as defined by this category, is designed to cook food by burning a fuel gas. The primary focus of this particular gas grill is its compact design to simplify transport. This is achieved by using a frame assembly made up of plug-in components, allowing for easy assembly and disassembly. The frame components can then be stored compactly for transport.

[0003] One challenge with a compact gas grill design is ensuring sufficient stability and a secure arrangement of components. A crucial aspect for optimal grilling performance is the positioning of the burner tube within the combustion chamber of the frame. The burner tube is responsible for gas supply and combustion and therefore has at least one combustion opening, which must be positioned precisely within the combustion chamber and relative to the grill grate.

[0004] The invention is based on the problem of designing and further developing a gas grill of the generic type in such a way that further optimization is achieved with regard to the aforementioned challenge.

[0005] The above problem is solved by the features of claim 1.

[0006] The fundamental principle is that, for ease of assembly and increased compactness, the burner tube can be inserted through a front frame section and positioned against a rear frame section. Accordingly, the frame assembly can be put together first, followed by the placement of the burner tube. The geometric degrees of freedom required for inserting the burner tube can then be limited by the interaction between the burner tube and the frame sections to ensure correct positioning.

[0007] Specifically, it is proposed that the combustion tube have a locking element which, upon insertion of the combustion tube, can be brought into engagement with the front frame part in such a way that the combustion tube is secured in a defined rotational position around its longitudinal axis by means of this engagement with the front frame part. Securing this defined rotational position ensures, in particular, the correct alignment of at least one combustion opening.

[0008] The locking of the rotational position can be implemented in a simple manner via the engagement between a locking recess and a locking projection according to claim 2.

[0009] Particularly preferably, according to claim 3, the combustion tube is additionally secured in a defined longitudinal position in the insertion direction by means of the locking element, thus giving the locking element a multiple function. A particularly simple implementation of this measure is provided by a locking element projecting beyond the contour of an insertion opening, as described in claim 4.

[0010] In the advantageous embodiments according to claims 5 to 7, a rotatable locking element on the combustion tube is provided for further securing the defined longitudinal position.

[0011] The preferred embodiment according to claim 8 relates to a flame retardant which can be mounted on the frame arrangement by means of retaining projections.

[0012] The pluggable and, in particular, plate-shaped design of the parts of the frame arrangement according to claim 9 contributes to the already mentioned compact and easily transportable design of the gas grill.

[0013] Particularly preferred is a pivotable and removable further development of the grill grate according to claims 11 and 12, which facilitates access to the combustion chamber. In particular, the frame assembly can be assembled and disassembled independently of the grill grate.

[0014] The invention will now be explained in more detail with reference to a drawing that merely illustrates exemplary embodiments. The drawing shows Fig. 1. A proposed gas grill in an exploded view, Fig. 2. The gas grill in a perspective view, Fig. 3. The gas grill in perspective views with a) the grill grate in the grilling position, b) the grill grate in the open position and Fig. 4 a) the gas grill in a top view, b) a detailed view of the safety element.

[0015] The embodiment shown in the figures, which is preferred in this respect, relates to a gas grill 1 for preparing grilled food by burning a fuel gas.

[0016] The gas grill 1 is equipped with a frame assembly comprising a front frame part 2 and a rear frame part 3. The terms "front" and "rear" frame part are to be understood broadly and are used here in reference to an insertion movement described below. In particular, the terms "front" and "rear" frame part do not refer to a specific orientation of the respective frame parts 2 and 3 during operation of the gas grill 1 relative to a user. The frame assembly forms a combustion chamber 4. The combustion chamber 4 is designed for burning the fuel gas and is preferably formed by a space between the front frame part 2 and the rear frame part 3, with the frame parts 2 and 3 defining the boundaries of the combustion chamber 4.

[0017] The gas grill 1 is equipped with a grill grate 5 mounted on the frame assembly of the combustion chamber 4. The grill grate 5 serves as a support for the food to be grilled during operation of the gas grill 1. The grill grate 5 is mounted here, and preferably at a section of the combustion chamber 4 provided above during operation.

[0018] The gas grill 1 is further equipped with a burner tube 6, which has a gas supply element 7 and at least one combustion opening 8 in a tubular base 9. The gas supply element 7 serves to connect the burner tube 6 to a fuel gas source and is not shown in detail in the drawing. For example, the gas supply element 7 has a connection hose, a valve, a pressure regulator, a pressure gauge, and / or an adapter for a gas cartridge or the like. Fuel gas can be fed into the interior of the burner tube 6 via the gas supply element 7, from where it can exit at the at least one combustion opening 8 and be ignited. Several combustion openings 8 are preferably provided along a geometric longitudinal axis 10 of the burner tube 6. The tubular base 9 preferably has a circular cross-section along the longitudinal axis 10.The longitudinal axis 10 is therefore a preferred direction, in particular an axis of symmetry of the pipe body 9.

[0019] To achieve a high degree of compactness for the gas grill 1 when disassembled, the burner tube 6 is detachably connected to the frame. The burner tube 6 can be inserted into the combustion chamber 4 and removed from the combustion chamber 4. For the insertion movement, the burner tube 6 can be slid axially into the combustion chamber 4 through the front frame part 2 along an insertion direction relative to the longitudinal axis 10 of the burner tube 6 and brought into contact with the rear frame part 3. The tube body 9 is positioned at least partially, and preferably at least with its combustion openings 8, within the combustion chamber 4 during the insertion movement. The insertion movement is guided in particular by means of Fig. Figure 1 shows the insertion direction symbolized by the arrow. The insertion movement preferably occurs predominantly axially to the longitudinal axis 10. The gas supply element 7 is preferably arranged at the end of the tube base 9 opposite to the insertion direction and, in the inserted position, is located outside the combustion chamber 4 ( Fig. 4a)), so that it is not absolutely necessary to guide the gas supply element 7 through the front frame part 2 during the insertion movement.

[0020] The burner tube 6 is held in the retracted position by the support against the rear frame part 3. Furthermore, the burner tube 6 is held by interaction with the front frame part 2, preferably also initially by a support against the front frame part 2. By "support," we mean that the burner tube 6 is held in place, at least in the orientation of the gas grill 1, by its own weight during operation.

[0021] Furthermore, it is provided here that the combustion tube 6 has a locking element 11 which, when the combustion tube 6 is inserted, can be brought into engagement with the front frame part 2 in such a way that the combustion tube 6 is secured in a defined rotational position about the longitudinal axis 10 by means of the engagement with the front frame part 2.

[0022] The locking element 11 is preferably arranged on an end section of the tube body 9 opposite to the insertion direction and is located outside the combustion chamber 4 when the burner tube 6 is inserted. By setting the defined rotational position, the at least one combustion opening 8 is brought into a defined orientation within the combustion chamber 4. For example, it is provided that the combustion openings 8 are arranged laterally during operation of the gas grill 1, approximately along a horizontal section through the burner tube 6 along the longitudinal axis 10, and in particular on both sides ( Fig. 1).

[0023] In particular, in the embodiment described, which includes a pipe base 9 with a round cross-section, anti-rotation protection is not necessarily implemented via the pipe base 9, but can be achieved via the locking element 11. Accordingly, the pipe base 9 can be designed to be particularly simple and cost-effective.

[0024] Furthermore, and preferably, it is provided here that the locking element 11 has a locking recess 12, and that the engagement with the front frame part 2 in the defined rotational position is effected via a locking projection 13 of the front frame part 2 engaging in the locking recess 12. As can be seen in particular from Fig. As is clearly shown in Figure 1, the locking projection 13 is provided here, and preferably on an outer surface of the front frame part 2. The locking projection 13 can be designed, for example, as a rivet element, a through-hole, a bend, or the like. To achieve the inserted position of the burner tube 6, the burner tube 6 must be brought into the defined rotational position, at least at the end of the insertion movement, so that the locking projection 13 engages in the locking recess 12. The engagement of the locking projection 13 in the locking recess 12 then secures the burner tube 6 against rotation.

[0025] Preferably, reaching the support on the rear frame part 3 requires that engagement with the front frame part 2 is effected, for example by coordinating the length of the burner tube 6 and the locking element 11 and locking projection 13. Accordingly, the burner tube 6 can only assume a sufficiently stable position, as is apparent to the user, when the locking of the rotational position is also effected.

[0026] In principle, several rotational positions can be defined, which can be secured by means of the locking element 11. For example, the locking element 11 can have several locking recesses 12, each corresponding to a rotational position with a corresponding engagement with the locking projection 13.

[0027] Furthermore, and preferably, it is provided that the combustion tube 6 is secured in a defined longitudinal position in the insertion direction by means of a locking element 11 against the front frame part 2. Here, and preferably, the locking of the defined longitudinal position occurs only in one direction, namely the insertion direction, so that the combustion tube 6 cannot be inserted further. For this "locking" to occur, a constant mechanical contact between the components in the inserted position is not absolutely necessary. Rather, it is sufficient if mechanical contact is achieved when the combustion tube 6 is moved out of the inserted position.

[0028] Here, and preferably, the front frame part 2 has an insertion opening 14 for the combustion tube 6, through which the combustion tube 6 can be inserted into the combustion chamber 4. The contour of the insertion opening 14 is preferably a closed contour.

[0029] Preferably, when the burner tube 6 is inserted, the locking element 11 projects radially to the longitudinal axis 10 beyond the contour of the insertion opening 14. The locking element 11 thus has a projection in cross-section perpendicular to the longitudinal axis 10 relative to the insertion opening 14, preventing it from being inserted through the opening 14. Instead, during the insertion movement, the locking element 11 comes into contact with the front frame part 2 and secures its longitudinal position in the insertion direction. Fig. 4) Here, and preferably, the locking element 11 is round in cross-section with respect to the longitudinal axis 10 - apart from the locking recess 12 - preferably circular in shape, wherein the locking element 11 has a larger diameter than the pipe body 9.

[0030] Furthermore, and preferably, it is provided here that the combustion tube 6 has a locking element 15 rotatable about the longitudinal axis 10, which in at least a first rotational position enables the combustion tube 6 to be inserted to rest against the rear frame part 3 and which in at least a second rotational position secures the combustion tube 6 in the defined longitudinal position opposite the insertion direction by means of a contact against the rear frame part 3. Accordingly, the insertion movement can be carried out with the locking element 15 in the first rotational position and the combustion tube 6 can be secured by moving the locking element 15 into the second rotational position, as exemplified in Fig. 2 is shown.

[0031] Particularly preferably, the combustion tube 6 is secured in the defined longitudinal position via the front frame part 2 in one direction axially to the longitudinal axis 10 and via the rear frame part 3 in a further direction axially to the longitudinal axis 10. In the illustrated embodiment, this is achieved, as already described, on the one hand by the securing element 11 and on the other hand by the locking element 15 (see Figure 1). Fig. 4).

[0032] Preferably, the locking element 15 has at least one wing element 16 projecting radially to the longitudinal axis 10 beyond the tube base body 9, which in the second rotation position causes the locking element to come into contact with the rear frame part 3, preferably, the rear frame part 3 has a receiving opening 17 for pushing through the locking element 15, the shape of which corresponds to the cross-section of the tube base body 9 perpendicular to the longitudinal axis 10 and of the locking element 15 in the first rotation position.

[0033] As the illustration shows Fig. As can be seen from Figure 2, the locking element 15 can be pushed through the receiving opening 17 in the first rotational position, so that the pipe base 9 rests against the receiving opening 17. The receiving opening 17 has a round basic shape corresponding to the cross-section of the pipe base 9, with two additional wing elements 16 having corresponding recesses in the first rotational position ( Fig. 2 - upper detail view). By rotating the locking element 15 into the second rotation position, the wing elements 16 engage behind the receiving opening 17 and the rear frame part 3 ( Fig. 2 - lower detail view and Fig. 4a)).

[0034] It is further preferably provided that the shape of the insertion opening 14 corresponds to the cross-section of the pipe base 9 perpendicular to the longitudinal axis 10 and of the locking element 15 in the first rotational position. In particular, the insertion opening 14 and the receiving opening 17 are identically designed. This eliminates the need to rotate the locking element 15 during the insertion movement.

[0035] Furthermore, it is preferably provided here that a flame guard 18 is arranged in the combustion chamber 4 between the burner tube 6 and the grill grate 5. The flame guard 18 is shown by way of example in Fig. The flame guard 18 is shown in Figure 1 and can be used to cover the burner tube 6 from the food being grilled, for example for indirect grilling and / or to protect the burner tube 6. The flame guard 18 is particularly preferably mounted on retaining projections 19 of the frame assembly, especially of the front frame part 2 and / or the rear frame part 3. In a particularly preferred embodiment, the flame guard 18 can be held on the retaining projections 19 solely by its own weight.

[0036] Here, and preferably, one of the frame parts 2, 3 has three retaining projections 19 (in Fig. 1 the rear frame part 3) and the further frame part 2, 3 via a retaining projection 19 (in Fig. 1 the front frame part 2). The flame guard can rest on a retaining projection 19. The two additional retaining projections 19 on one of the frame parts 2, 3 can be arranged above the flame guard 18 during operation, thus easily securing the flame guard 18 against tilting. The retaining projections 19 can be designed as rivets, through-bolts, bends, or the like.

[0037] Furthermore, it is preferably provided that the frame arrangement has side parts 20, via which the front frame part 2 and the rear frame part 3 are connected to each other, in particular in a pluggable manner, preferably that the side parts 20, the front frame part 2 and / or the rear frame part 3 is / are designed in a plate-like form.

[0038] The plate-like design allows the frame components to be stacked for easier transport. The plug-in connection of the components allows for the assembly and disassembly of the gas grill 1, preferably without tools. In the illustrated and therefore preferred embodiment, the front frame component 2, the rear frame component 3, and the side components 20 each have slots on their sides, which are inserted into one another to create the connection between the components.

[0039] The side panels 20 can be arranged at an angle to each other when the gas grill 1 is in operation and preferably converge towards each other with an increasing distance from the grill grate 5. The front frame part 2 and the rear frame part 3 preferably each have feet 21 for positioning the gas grill 1 on a surface, with the side panels 20 preferably not being in contact with the surface.

[0040] Furthermore, it is preferably provided that the frame arrangement has a bottom part 22 which is arranged between the front frame part 2 and the rear frame part 3 at the combustion chamber 4, preferably that the bottom part 22 has a curved or flat shape.

[0041] In the operating state of the gas grill 1, the base section 22 can form the lower boundary of the combustion chamber 4. Furthermore, the base section 22 can enable the alternative use of the gas grill 1 with charcoal, for example, with the burner tube 6 extended, for which the curved shape is particularly advantageous. The base section 22 is connected here, and preferably via plug connections, to the front frame section 2 and the rear frame section 3, so that the frame assembly is further stabilized by means of the base section 22.

[0042] Furthermore, and preferably, it is provided here that the grill grate 5 is pivotally mounted on the frame assembly, in particular on the front frame part 2 and the rear frame part 3, at a side area between a grilling position and an open position via a pivot bearing. The grilling position ( Fig. 3a)) is intended for the operation of the gas grill 1 and allows food to be placed on the grill grate 5. The open position ( Fig. 3b)) enables access to the combustion chamber 4, in particular to support the insertion movement, to insert the flame guard 18 or for alternative use with charcoal.

[0043] Preferably, the grill grate 5 has a handle 23, preferably on a side opposite the side area, for pivoting the grill grate 5. The handle 23 can preferably be provided centrally on the side opposite the side area, so that the grill grate 5 can be easily lifted and adjusted between the grilling position and the open position, for example, when operating the gas grill 1, using tongs or the like.

[0044] The grill grate 5 is preferably arranged between the side panels 20, and in particular between the front frame part 2 and the rear frame part 3, such that the frame assembly projects beyond the grill grate 5, serving as a boundary for the grilling area. The handle element 23 rests in a handle element recess 24 of one of the side panels 20.

[0045] The side parts 20 are preferably provided with support recesses 25, which serve in particular for the support of skewers or the like.

[0046] Furthermore, and preferably, the pivot bearing is designed such that the grill grate 5 can be removed from the frame assembly in a release position, particularly one provided between the grilling position and the open position, and is secured against removal outside of this release position. The release position corresponds here to a vertical alignment of the grill grate 5 during operation of the gas grill 1.

[0047] Preferably, the pivot bearing is formed by bearing projections 27 engaging in bearing openings 26 of the frame assembly; further preferably, the bearing openings 26 have respective stop surfaces 28 for the open position, retaining surfaces 29 for the grill position for contact with the bearing projections 27, and a release opening 30 for removing the grill grate 5. The shape of the bearing openings 26 is shown by way of example in the Fig. 3 stands out.

[0048] Furthermore, and preferably, a drip tray 31 is provided that can be inserted between the front frame part 2 and the rear frame part 3, here located below the combustion chamber 4 during operation; preferably, the drip tray 31 is slidably mounted on the respective bends of the front frame part 2 and the rear frame part 3; and more preferably, at least one stop element 32 is provided on the front frame part 2 and / or the rear frame part 3 to secure the drip tray 31. The securing of the drip tray 31 serves as a limit to its insertion.

[0049] Furthermore, it is preferably provided here that the front frame part 2 has an adjustable cover element 33 for the insertion opening 14 and / or the rear frame part 3 has an adjustable cover element 33 for the receiving opening 17, which is particularly advantageous in Fig.2. The cover element 33 is mounted here, preferably rotatably, on the respective frame part 2, 3, for example by means of a rivet element or the like. The combustion chamber 4 can be further closed by means of the cover element 33, particularly for transport or for operation with coal.
