<p>A double-walled caravan window comprises a flat plastic sheet (2) which is bonded by its peripheral edge to a dish-shaped plastic sheet (3) whose peripheral edge is profiled so that it is stepped. The window has at least one fitting cap (10) for fixing a setback hinge or lock. In order to ensure that the fitting cap does not project relative to the plane of the shaped sheet, and in order to make it possible for the fitting cap to be fitted at the factory where the double-walled windows are made, in a part (7) of the stepped peripheral edge of the dish-shaped sheet (3) running parallel to the flat sheet (2) provision is made for a recess (11) extending to the flat sheet and bonded by its bottom in sealing fashion to the flat sheet. The fitting cap (10) is housed in the recess (11), while one or more hollow pins (12a, 12b) connected to the cap project through bores in the bottom of the recess and the flat sheet. The cap (10) is fixed by the locking rings (14) slid onto the end of the pins (12a, 12b).</p> |
