Claims14
Glass or glass ceramic plate for a kitchen appliance, especially a cooking or baking surface, wherein the plate has a safe edge, characterized in that the safe edge is formed by a cross-sectional profiled portion (5) thicker than the thickness (D) of the plate (1), which merges integrally and seamlessly with the plate (1) and is upset or shaped on the rolled plate (1).
Glass or glass ceramic plate according to either of the foregoing claims, characterized in that the upper side (2) and/or the lower side (3) of the plate is flat within the profiled portion (5).
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) is a holding zone for the mounting of the plate (1).
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) is rounded at the edge.
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) runs around the plate (1).
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) is rounded at the comers (15) of the plate (1).
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) is elevated by a height (H1) over the flat upper side (2) of the plate (1) such that a catchment for liquid is formed.
Glass or glass ceramic plate according to any one of the foregoing claims, characterized in that the profiled portion (5) merges at a convex round (8) and a concave round (6′) into the bottom side (3) of the plate (1).
Method for the manufacture of a glass or glass ceramic plate for a kitchen appliance, which has a safe edge, characterized in that the plate is first made by rolling and then, in the green state, is upset or shaped such that there a profiled portion thickened in relation to the thickness of the plate is formed, and that then the plate is heat treated and/or ceramicized to reach its finished state.
