Abstract (en)
[origin: EP0122413A1] 1. Chimney cowl for mounting on the upper end of a chimney, comprising an inner frame part (10) and an outer frame part (11) secured thereon, between which a perpendicular intermediate space is formed, in which the outer frame part is displaced vertically upwards relative to, and has a greater cross-section than, the inner frame part, the lower edge of the outer frame part lying below the upper edge of the inner frame part, and in which the two frame parts are connected together by plate-like struts (12) which span the space between the two frame parts and hinder lateral spreading of wind on the chimney, the chimney cowl housing in its upper region has a central cover (13), for preventing the entry of precipitation and the sun's rays, which overlies the inner frame part and, with the outer frame part, leaves free a peripheral outlet gap for the smoke, characterized in that the outer frame part (11) widens from its lower edge to its upper edge, that the cover (13) substantially overlies the region enclosed by the lower edge of the outer frame part, that the platelike struts (12) are arranged diagonally in the corners and that the outer and inner frame parts (10, 11) and the plate-like struts (12), as well as the area overlain by the cover (13), form wind chambers, the breadth of which is substantially greater than their height.
