[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

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

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

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).
