Arrangement of at least one gas burner in a molded part of a brittle-friable material for example for cooking units

A burner arrangement useful in cooking units, wherein at least one gas burner is mounted in a supporting frame and surrounded by a molded part of a brittle-friable material having a topside;

• wherein each gas burner extends through an opening in the molded part of the brittle-friable material up to and beyond the topside of the molded part, and wherein, between the molded part and each gas burner, an elastic junction and sealing device is provided with a junction and sealing element in firm contact and in liquid-tight engagement with a marginal zone of the opening and with at least one junction surface formed by the gas burner;
• the improvement comprising the gas burner (7) being carried by a molded part (5), the molded part (5) being in the form of a plate made of a brittle-friable material, locking means (16 or 35) for fixing the gas burner (7) to the molded part (5) and retaining means (3) secured to the frame (2) beneath the molded part (5) and spaced from the molded part (5), the retaining means (3) being out of direct mechanical contact with the molded part (5), the gas burner (7) and the locking means (16 or 35);
• wherein the retaining means will support the gas burner (7) upon breakage of the molded part (5) while allowing the burner (7) to move and twist with respect to the molded part (5) under normal circumstances whereby stresses in the molded plate (5) due to the thermal and mechanical loading by the burner (7) are minimized.
