<p>The present invention relates to a hinge arrangement for an oven hatch, wherein a hatch arrangement comprises a hatch door part manufactured as a casting, an immuration or masonry frame as well as a hinge structure functioning between said parts. A body part (15) and a pin part (14) of the hinge constitute a separate hinge element (4a) comprising at least two mutually pivotable portions, which portions by means of adjoining surfaces (6, 6a, 6b) connect to corresponding adjoining surfaces formed in the respective pieces to be connected. The present invention also relates to a method for interconnecting oven hatch parts manufactured as castings, by means of a hinge element (4a) comprising mutually pivotable parts. Mutually essentially congruent adjoining surfaces (6, 6a, 6b) are formed in said hinge element (4a) and said castings, respectively, and said mutually pivotable parts of said hinge element (4a) are attached to respective oven hatch parts (2, 3, 8) by means of transverse elements (11) extending therethrough.</p> |
