Abstract

The present invention relates to a burner body ( 10 ) for a domestic appliance, in particular for a gas cooking hob. The burner body ( 10 ) comprises two lateral wings arranged in a lower portion of said burner body ( 10 ). Said lateral wings are arranged at opposite sides of the lower portion of the burner body ( 10 ). The lateral wings are arranged parallel to each other. The burner body ( 10 ) is fixable on the domestic appliance by a horizontal movement, so that the lateral wings are engageable with complementary elements ( 16 ) of the domestic appliance. Further, the present invention relates to a metal sheet plate ( 12 ) of a domestic appliance, in particular a gas cooking hob. The metal sheet plate ( 12 ) comprises at least one punched hole. Two slide rails ( 16 ) are formed at opposite sides of the punched hole. The slide rails ( 16 ) are formed as L-shaped profile parts. The slide rails ( 16 ) are provided for receiving at least one complementary element of a burner body ( 10 ). Moreover, the present invention relates to a fastening system for the burner body ( 10 ) on the metal sheet plate ( 12 ) of the domestic appliance.

First claim

1 . A burner body for a domestic gas cooking hob, wherein:
the burner body comprises two lateral wings arranged in a lower portion of said burner body, said lateral wings are arranged at opposite sides of the lower portion of the burner body, the lateral wings are arranged parallel to each other, and the burner body is fixable on the gas cooking hob by a horizontal movement, so that the lateral wings are engageable with complementary elements of the domestic appliance.

2 . The burner body according to claim 1 , further comprising a base plate arranged in the lower portion of said burner body, wherein the lateral wings are arranged at opposite sides of said base plate.

3 . The burner body according to claim 2 , wherein the base plate is rectangular.

4 . The burner body according to claim 1 , further comprising at least one pin element engageable with a complementary receiving hole, an end portion of an elongated cut-out or a shaped hole of a slot.

5 . A metal sheet plate for a domestic gas cooking hob, wherein:
the metal sheet plate comprises at least one punched hole, two slide rails are formed at opposite sides of the punched hole, the slide rails are formed as L-shaped profile parts, and the slide rails are provided for receiving at least one complementary element of a burner body.

6 . The metal sheet plate according to claim 5 , wherein the slide rails extend upwards from a plane of the metal sheet plate.

7 . The metal sheet plate according to claim 5 , wherein the at least one punched hole is subdivided into two punched holes separated by a connecting plate, wherein the two slide rails are formed at outermost opposite sides of the subdivided punched holes.

8 . The metal sheet plate according to claim 5 , further comprising at least one tab element formed as an appendix of the metal sheet plate and extending inwardly within the at least one punched hole.

9 . The metal sheet plate according to claim 8 , wherein the tab element includes at least one receiving hole for a protruding element of the burner body.

10 . The metal sheet plate according to claim 8 , wherein the tab element includes at least one support element formed as an appendix of the metal sheet plate and arranged opposite to the tab element.

11 . The metal sheet plate according to claim 5 , further comprising at least one elongated cut-out or slot for receiving and guiding a protruding element of the burner body during a movement of said burner body, wherein a longitudinal axis of said elongated cut-out ( 30 ) or slot, respectively, extends parallel to the slide rails.

12 . The metal sheet plate according to claim 5 , further comprising at least one tongue element formed within a further punched hole and extending parallel to the slide rails, wherein the at least one tongue element forms a snap-in mechanism with the burner body.

13 . The metal sheet plate according to according to claim 11 , wherein the slot includes a widened hole at its one end portion and a shaped hole at its other end portion, wherein the widened hole is provided for inserting the protruding element of the burner body, while the shaped hole is provided for engaging with said protruding element of the burner body.

14 . A domestic gas cooking hob comprising the burner body according to claims 1 , and a metal sheet plate comprising two opposing L-shaped slide rails formed therein, the slide rails being adapted to complementarily receive said lateral wings of said burner body in order to fasten said burner body to said metal sheet plate.

15 . The domestic gas cooking hob according to claim 14 , further comprising a pin element of the burner body and a tab element associated with a receiving hole of the metal sheet plate, said pin element and said tab element with said receiving hole together forming a snap-in mechanism to affix said burner body to said metal sheet plate.

16 . The metal sheet plate according to claim 8 , said tab element being inclined downwards.

17 . The metal sheet plate according to claim 11 , further comprising at least one tongue element formed within a further punched hole and extending parallel to the slide rails, wherein the at least one tongue element forms a snap-in mechanism with the burner body, and wherein the tongue element and the elongated cut-out are arranged side by side.

18 . A domestic gas cooking hob comprising:
a gas burner having a burner body with a base plate comprising a pair of lateral wings opposing and extending parallel to one another at a lower portion of the burner body; a metal sheet plate adapted to support the gas burner and comprising a pair of spaced slide rails opposing and extending parallel to one another, said slide rails being formed as taps punched in the sheet metal plate so that they extend above an upper surface of the sheet metal plate, said slide rails being spaced apart from one another so as to slidingly accommodate therebetween the base plate of said burner body, including said pair of lateral wings thereof, along a sliding axis parallel to the slide rails, wherein said slide rails further are shaped to complementarily engage the respective opposing wings of said base plate so as to permit sliding thereof along said sliding axis but to inhibit movement thereof transverse to said sliding axis; wherein upon translating said gas burner horizontally along said sliding axis with said opposing wings of the base plate engaged with the opposing slide rails of the metal sheet plate, said gas burner and said metal sheet plate are configured to achieve a snap-fit connection therebetween that inhibits further horizontal translation along said sliding in either direction, thereby fixing said gas burner to said metal sheet plate.

19 . The domestic gas cooking hob according to claim 18 , said burner body further comprising a pin protruding downward, said metal sheet plate comprising a hole adapted to accommodate said pin, wherein said pin and said hole interact to provide said snap-fit connection.

20 . The domestic gas cooking hob according to claim 18 , said hold being provided in a deflectable tab or tongue formed as an appendage of said metal sheet plate and extending within a punched opening in the metal sheet plate, the hole being formed in said tab or tongue, the pin adapted to slide over and thereby deflect said tab or tongue upon translation of the burner body along said sliding axis until said pin reaches and is accommodated within said hole to thereby establish said snap-fit connection.
