[0028] FIG 1 illustrates a schematic perspective view of a burner body 10 attached at a metal sheet plate 12 according to a first embodiment of the present invention. In particular, the metal sheet plate 12 is a part of a gas cooking hob. Preferably, the metal sheet plate 12 extends horizontally. For example, the metal sheet plate 12 is made of steel, stainless steel or aluminium, preferably steel.

[0029] The burner body 10 comprises a base plate 14 at its bottom side. Said base plate 14 includes two lateral wings extending parallel to each other. The metal sheet plate 12 includes two parallel slide rails 16. Said slide rails 16 are formed complementary to the lateral wings of the base plate 14, so that the base plate 14 is slide-in and inserted between the slide rails 16. Thus, the burner body 10 is attachable at the metal sheet plate 12 by a sideward movement of said burner body 10, wherein the base plate 14 is inserted between the slide rails 16.

[0030] In this example, the slide rails 16 are formed by punching a hole in the metal sheet plate 12 and bending two opposite borders of said hole. The slide rails 16 are formed as L-shaped profile parts.

[0031] FIG 2 illustrates a schematic perspective partial bottom view of the metal sheet plate 12 with the burner body 10 according to the first embodiment of the present invention. The base plate 14 of the burner body 10 is inserted between the slide rails 16.

[0032] Further, the metal sheet plate 12 includes a tap element 18 formed within the punched hole of said metal sheet plate 12. The tap element 18 extends inwardly within the hole. The tap element 18 is an appendix of the metal sheet plate 12. Moreover, the tap element 18 is inclined downwards. Further, the tap element 18 is elastic. Preferably, the tab element (18) is formed as an integral part of the metal sheet plate (12). For example, the tab element (18) may be obtained by cold stamping of the metal sheet plate (18). Thereby it is to be understood that the thickness of said tab element (18) may be same or different to the thickness of the metal sheet plate (12). Preferably, the thickness of the tab element (18) and the metal sheet plate (12) are similar. Particularly, in case that the tab element (18) may be obtained by cold stamping of the metal sheet plate (18) the thickness of both may be approximately uniform. A person skilled in the art, however, will immediately acknowledge that also in such case the thickness of the tab element (18) and the thickness of the metal sheet plate (18) may slightly vary due to the stamping process that may particularly entail little stretching effects.

[0033] A pin element 20 is formed at the bottom side of the burner body 10. A receiving hole 22 is formed in the tap element 18. The pin element 20 of the burner body 10 penetrates the receiving hole 22 in the tap element 18, when said burner body 10 is attached at the metal sheet plate 12. Since the tap element 18 is inclined downwards, the pin element 20 of the burner body 10 and the hole in the tap element 18 form a snap-in mechanism.

[0034] FIG 3 illustrates a further schematic perspective view of the burner body 10 attached at the metal sheet plate 12 according to the first embodiment of the present invention.

[0035] The burner body 10 comprises the base plate 14 including the two lateral wings. The metal sheet plate 12 includes the two parallel slide rails 16 formed complementary to the lateral wings of the base plate 14. The base plate 14 is slide-in and inserted between the slide rails 16. The pin element 20 of the burner body 10 penetrates the receiving hole 22 in the tap element 18.

[0036] FIG 4 illustrates a schematic sectional side view of the burner body 10 attached at the metal sheet plate 12 according to the first embodiment of the present invention.

[0037] The base plate 14 of the burner body 10 is aligned on the top side of the metal sheet plate 12. FIG 4 clarifies that the tap element 18 is inclined. The pin element 20 of the burner body 10 penetrates the receiving hole 22 in the tap element 18. When the burner body 10 is fastened at the metal sheet plate 12, then said burner body 10 has to be moved from the right hand side to the left hand side in FIG 4, wherein the pin element 20 and the tap element 18 with the receiving hole 22 form the snap-in mechanism.

[0038] FIG 5 illustrates a further schematic perspective view of the burner body 10 attached at the metal sheet plate 12 according to the first embodiment of the present invention.

[0039] The lateral wings of the base plate 14 are engaged with the slide rails 16 of the metal sheet plate 12. In FIG 5, the base plate 14 has been moved rearwards into the slide rails 16.

[0040] FIG 6 illustrates a further schematic perspective view of the burner body 10 attached at the metal sheet plate 12 according to the first embodiment of the present invention.

[0041] The lateral wings of the base plate 14 are engaged with the slide rails 16 of the metal sheet plate 12. In FIG 6, the base plate 14 has been moved into the slide rails 16 from the left in the back to the right in the front.

[0042] FIG 7 illustrates a schematic perspective partial view of the metal sheet plate 12 with a fastening system for the burner body 10 according to the first embodiment of the present invention.

[0043] The metal sheet plate 12 includes the punched hole. In this example, said punched hole is substantially rectangular. The slide rails 16 are arranged at opposite sides of the punched hole. The slide rails 16 are bent from tap elements punched in the metal sheet 12. The slide rails 16 are formed as L-shaped profile parts. The space between the slide rails 16 is marginally bigger than the base plate 14 of the burner body 10. The space between the slide rails 16 is complementary to the base plate 14 of the burner body 10. The lateral wings of the base plate 14 are engageable with the slide rails 16.

[0044] The tap element 18 is formed within the punched hole of the metal sheet plate 12. The tap element 18 extends inwardly within the punched hole. The tap element 18 is an appendix of the metal sheet plate 12. In particular, the tap element 18 is inclined downwards.

[0045] The tap element 18 includes the receiving hole 22. In FIG 7, the receiving hole 22 in the tap element 18 is an open hole. In contrast, the receiving hole 22 of the tap element 18 in FIG 2 is a closed through hole.

[0046] Optionally, a support element 24 is formed in the punched hole of the metal sheet plate 12. Said support element 24 is formed as an appendix of the metal sheet plate 12 and arranged opposite to the tap element 18. The support element 24 extends within the same plane as the metal sheet plate 12. The support element 24 is provided for supporting the base plate 14 of the burner body 10.

[0047] The burner body 10 with the base plate 14 and the lateral wings on the one hand and the slide rails 16 at the metal sheet plate 12 on the other hand provide a fastening system for the burner body 10 on the metal sheet plate 12. The burner body 10 is fixable on the metal sheet plate 12 without any additional fastening element. The burner body 10 is fixable on the metal sheet plate 12 by a horizontal movement of said burner body 10. The snap-in mechanism formed by the pin element 20 on the one hand and the inclined tap element 18 with the receiving hole 22 on the other hand allows a reliable connection between the burner body 10 and the metal sheet plate 12.

[0048] FIG 8 illustrates a schematic perspective partial view of the metal sheet plate 12 with the fastening system for the burner body 10 according to a second embodiment of the present invention.

[0049] The metal sheet plate 12 of the second embodiment includes two punched holes arranged side by side. A connecting plate 26 is formed between said punched holes. In this example, said punched holes are substantially rectangular. In each punched hole, one slide rail 16 is bent from a tap element punched in the metal sheet 12. Said slide rails 16 are arranged at the outermost sides of the both punched holes. The slide rails 16 are arranged parallel to each other. Each slide rail 16 is formed as L-shaped profile part. The space between the slide rails 16 is marginally bigger than the base plate 14 of the burner body 10. The space between the slide rails 16 is complementary to the base plate 14 of the burner body 10. The lateral wings of the base plate 14 are engageable with the slide rails 16. The base plate 14 of the burner body 10 is slide-in and inserted between the slide rails 16. The burner body 10 is attachable at the metal sheet plate 12 by the sideward movement of said burner body 10, wherein the base plate 14 is inserted between the slide rails 16.

[0050] Moreover, the metal sheet plate 12 includes a tongue element 28 formed within a further punched hole. Said tongue element 28 extends parallel to the slide rails 16. Further, the tongue element 28 and the pair of slide rails 16 are arranged in series. The open end of the tongue element 28 is directed to the pair of slide rails 16. The tongue element 28 is inclined upwards, so that the height of said tongue element 28 decreases with the distance from the pair of slide rails 16.

[0051] Further, the metal sheet plate 12 includes an elongated cut-out 30 arranged directly beside the tongue element 28. Said elongated cut-out 30 extends parallel to the tongue element 28. The elongated cut-out 30 includes a first end portion 32 and a second end portion 34. The first end portion 32 is more distant from the pair of slide rails 16, while the second end portion 34 is closer to said pair of slide rails 16. The elongated cut-out 30 is provided for receiving and guiding the pin element 20 of the burner body 10. Said elongated cut-out 30 forms a duct for the pin element 20 of the burner body 10.

[0052] The burner body 10 is fixable by the horizontal movement on the metal sheet plate 12. In FIG 8, the burner body 10 is fixable by a horizontal movement from right to left. During said horizontal movement, the base plate 14 of the burner body 10 is slide-in and inserted between the slide rails 16, while the pin element 20 of the burner body 10 is slide within the elongated cut-out 30. When the burner body 10 has overcome the tongue element 28, then said tongue element 28 prevents that the burner body 10 can be moved back. Thus, the tongue element 28 and the burner body 10 form a snap-in mechanism.

[0053] Moreover, the metal sheet plate 12 includes a screw hole 36, so that the burner body 10 is additionally fixable by a screw or the like.

[0054] FIG 9 illustrates a schematic perspective view of the burner body 10 attached at the metal sheet plate 12 according to the second embodiment of the present invention. FIG 9 shows a position before the burner body 10 is horizontally moved on the metal sheet plate 12 for fastening said burner body 10. In FIG 9, the burner body 10 is fixable by a horizontal movement from left to right.

[0055] The base plate 14 of the burner body 10 is not yet completely received by the slide rails 16. The pin element 20 of the burner body 10 is received by the first end portion 32 of the elongated cut-out 30. The tongue element 28 does not interact with the burner body 10. However, a person skilled in the art will immediately acknowledged that the tongue element 28 will be received in the shaped area on the bottom of the burner body, when the burner body is in fixed final position. The tongue element 28 will act as blocking element to avoid backwarding of the burner body. This is because the tongue element will remain placed in order to impede back step of the burner body (see also the tongue element 28 position in fig 11).

[0056] FIG 10 illustrates a further schematic perspective partial view of the metal sheet plate 12 with the fastening system for the burner body 10 according to the second embodiment of the present invention.

In each punched hole one slide rail 16 is bent from the tap element punched in the metal sheet 12. The slide rails 16 are arranged at the outermost sides of the both punched holes and arranged parallel to each other. Each slide rail 16 is formed as L-shaped profile part. The space between said slide rails 16 is marginally bigger than the base plate 14 of the burner body 10. The space between the slide rails 16 is at least partially complementary to the base plate 14 of the burner body 10. The lateral wings of the base plate 14 are engageable with the slide rails 16. The base plate 14 of the burner body 10 can be slide-in and inserted between the slide rails 16. The burner body 10 is attachable at the metal sheet plate 12 by the sideward movement of said burner body 10, wherein the base plate 14 is inserted between the slide rails 16.

[0058] The tongue element 28 is formed within the further punched hole and extends parallel to the slide rails 16. Moreover, the tongue element 28 and the pair of slide rails 16 are arranged in series, wherein the open end of the tongue element 28 is directed to the pair of slide rails 16. The tongue element 28 is inclined upwards, wherein the height of said tongue element 28 decreases with the distance from the pair of slide rails 16.

[0059] The elongated cut-out 30 is arranged directly beside the tongue element 28 and extends parallel to said tongue element 28. The elongated cut-out 30 includes the first end portion 32 and the second end portion 34, wherein the first end portion 32 is more distant from the pair of slide rails 16, while the second end portion 34 is closer to said pair of slide rails 16. The elongated cut-out 30 forms a duct for the pin element 20 of the burner body 10. The screw hole 36 allows that the burner body 10 is additionally fixable by a screw or the like.

[0060] FIG 11 illustrates a further schematic perspective view of the burner body 10 attached at the metal sheet plate 12 according to the second embodiment of the present invention. In FIG 11 the burner body 10 is fastened on the metal sheet plate 12.
