Arranged on a first side all around the opening (15) is a casing frame (30) in which the window is mounted. A border device (20) is provided all around the opening on an opposite side. The casing frame (30) and the border device (20) are connected to each other for axial adjustment transversely of the wall (10) while enclosing a wall part of the wall. The border device (20) comprises a relatively stiff frame body (21) which carries on a side facing toward the wall a flexible skirt (25) and lies sealingly against the wall therewith.

Description

(1) The invention will be further elucidated hereinbelow with reference to an exemplary embodiment and an accompanying drawing. In the drawing:

(2) FIG. 1 shows a front view of a part of a wall of a mobile accommodation according to an embodiment of the invention, as seen from a viewpoint inside a room situated therein;

(3) FIG. 2 shows a rear side of the border device as applied in the mobile accommodation of FIG. 1;

(4) FIG. 3 shows a side view of the border device of FIG. 2;

(5) FIG. 4 shows a cross-section along the line A-A in FIG. 1 of the border device of FIG. 2;

(6) FIG. 4A shows an enlargement of a part of the border device of FIG. 2.

(7) It is noted here that the figures are intended to be purely schematic and are not all drawn to (the same) scale. Some dimensions in particular may be exaggerated to greater or lesser extent for the sake of clarity. Corresponding parts are generally designated in the figures with the same reference numeral.

(8) FIG. 1 shows by way of illustration a part of a wall 10 of a mobile accommodation, such as a camper or caravan, in which a window opening 15 is recessed for receiving an optionally openable window. The wall bounds a room in the accommodation which provides a place to stay for the shorter or longer term, usually for recreational use. FIG. 4 shows wall 10 in cross-section. The wall comprises an insulating core 12 of a polymer foam, such as polyurethane foam or polystyrene foam, which is flanked on either side by hard outer shells 11, 13 of respectively aluminium or plastic on the outer side and plastic or wood on the inner side.

(9) Window 15 is pre-mounted together with hanging and closing fittings, not further shown here, in a casing frame 30 which is arranged externally in and/or round opening 15, see also FIG. 4. The casing frame is usually, as it is here, manufactured from aluminium. Mainly used for this purpose are extrusion profiles which are assembled to form the casing frame. Window 15 is here a double-walled transparent window composed of a set of combined transparent plastic plates of poly(methyl methacrylate) (PMMA) or a similar transparent plastic, these maintaining relative to each other a thermally and acoustically insulating cavity.

(10) Wall opening 15 is finished internally with a border device 20. This comprises one or more relatively stiff shell parts 21 together with a flexible, compressible skirt 25, which extend all around the window opening 15. On a rear side, see FIG. 2, a large number of snap fingers 22 extend from the shell part and are received in corresponding snap cavities in the casing frame. After mounting of casing frame 30 the border device 20 can be arranged in relatively rapid and simple manner by aligning the snap fingers 22 with the snap cavities and sliding them therein.

(11) The snap cavities have on their inner wall a series of successive shoulders or teeth whereby a coupling is brought about at successive positions while enclosing the intermediate wall part. The mutual connection is thus axially adjustable transversely of wall 10. This accommodates almost unavoidable variations in the wall thickness of walls in which the assembly of the border device (inner frame) and casing frame (outer frame) must be provided. Not only does this thickness vary per manufacturer/customer, but also between manufacturers. The assembly can be adapted thereto by bringing the border device and the casing frame closer or less close together while enclosing the wall part, wherein the snap fingers 22 will engage further or less far in the snap cavities.

(12) In order to prevent an inconvenient gap from inadvertently resulting on the inner side the border device comprises on the side facing toward the wall a flexible, compressible skirt 25. This skirt 25 is here formed by a foldable sheet of a suitable thermoplastic elastomer, for instance a polyolefin such as polypropylene, polyethylene or EPDM (ethylene propylene diene monomer) or a polystyrene block copolymer, which is moulded integrally on the shell part 21. Use is made for this purpose of a hybrid injection moulding process. Shell parts 21 are manufactured from acrylonitrile styrene acrylate (ASA), which in such an injection moulding process works well with the plastic used for the skirt 25. A relatively stiff, hard-shell shell part 21 from which a flexible, foldable skirt hangs downward for lying therewith against the wall 10 of the accommodation is thus produced in a single production step. Skirt 25 here adapts under pressure to a possible variation in wall thickness by compressing to greater or lesser extent and thus preventing a gap.

(13) All in all, the invention thus provides a particularly practical and flexible solution which, within its adjustability, is effective against thickness variations of the relevant wall. Although the invention has been described further on the basis of only a single exemplary embodiment, it will be apparent that the invention is by no means limited thereto. On the contrary, many variations and embodiments are still possible for a person with ordinary skill in the art.
