发明名称 Curved double-walled window designed for use in a caravan or camper van
摘要 The window comprises a first saucer-shaped plastic plate (2) which is curved and has a shaped edge, and a second plane plastic plate (4) which is curved, the edge strip of the second plate (4) and a sealing strip (flange, bead) (3) of the shaped edge of the first plate (2) being adhesively bonded one on top of the other. The bend in the sealing strip (3) of the first plate (2) and the bend in the second plate (4) extend along a line of curvature which is substantially shallower than the bend in that part of the first plate (2) which does not form part of the shaped edge. <IMAGE>
