MOBILE ACCOMMODATION, FRAMED WINDOW AND CLOSURE

Abstract

Mobile accommodation comprising a wall (10) with a wall opening (5) in which an openable window is arranged, which window is provided with closing means for keeping the window in a closed position. The closing means comprise a closure (30) with a handle (34) which is connected for rotation about a pivot axis (III) to the window, and with a protrusion (35) which, in a first position of the closure round the pivot axis, is in closing co-action with a shoulder on the edge of the wall opening. In a second position of the handle about the pivot axis, the protrusion is disengaged from the shoulder in order to release the window. The pivot axis (III) makes an obtuse angle with the window, which angle opens toward a hinge side of the window. In the first position the handle is oriented substantially parallel (I) to the window and in the second position points at an acute angle (a) toward the hinge side of the window.

Description

[0010] In the drawing:

[0011] FIG. 1 shows a front view of an exemplary embodiment of a mobile accommodation according to the invention;

[0012] FIGS. 2A,B show respectively a front view and top view of an exemplary embodiment of a closure according to the invention as applied in the mobile accommodation of FIG. 1 in closed position; and

[0013] FIGS. 3A,B show respectively a front view and side view of the closure of FIGS. 2A and 2B in opened position.

[0014] It is otherwise noted here that the figures are purely schematic and not always 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 designated in the figures with the same reference numeral.

[0015] Shown in FIG. 1 is a part of a wall 10 of a mobile accommodation such as a caravan or camper. The wall typically comprises a sandwich construction of a hard inner shell and outer shell of for instance aluminium or a suitable plastic with a thickness of several millimetres, wherein the interior is optionally covered with a wood design or other decorative wall finish. For an effective thermal insulation both shells are separated from each other by a foamed core several centimetres thick, of for instance polyurethane or polystyrene. The further details of such a wall construction in a mobile accommodation such as a camper, caravan, yacht or the like is assumed sufficiently known to a person with ordinary skill in the art.

[0016] Recessed into wall 10 is a wall opening 5 at the location of which a window is arranged in this example. This is an openable window which is provided for this purpose with opening arms 22 and a closable latch 30 and which is provided on a hinge side with a line hinge 26. This window is pre-mounted together with these hanging and closing fittings 22,24,30 in a form-retaining, relatively stiff casing frame 20,25 arranged all round in wall opening 5. Such a window is for this reason normally referred to as a framed window. The shown part of casing frame 20 in which the window will be hung and with which the whole lies within wall opening 5 is in this example formed directly and in one whole as injection-moulded part from a suitable plastic such as polyethylene, polystyrene, polypropylene or ABS. Hereby possible is an exceptionally light but sufficiently stiff construction with a high measure of freedom of shape and design.

[0017] The invention is highly suitable for windows which will often take up a significant part of a surface area of the wall. With the thermal insulation value of such a window in mind, the window takes a double-walled form. The window is constructed here from a first sheet body and a second sheet body connected thereto which in a central part enclose a cavity therebetween but on their periphery make mutual contact with edge parts along which the two sheet bodies are attached to each other. The sheet bodies are more particularly formed from the same translucent plastic, in particular a transparent plastic from a group comprising polymethyl methacrylate (PMMA), polyethylene terephthalate glycol (PETG), polycarbonate (PC) and polyester.

[0018] Use is therefore made in this example of such a double-walled window with a set of transparent plastic sheet bodies of PMMA, wherein the outward facing pane is wholly flat and the inner pane is dish-shaped. The two panes hereby enclose at a central part an insulating cavity relative to each other. The two panes make contact with each other along their whole periphery with respective flat edge parts which are glued to each other to form an integral and stiff assembly. A sealing profile 8 of a suitable elastomer is arranged between the window and casing frame 20 for a watertight closure. Casing frame 20 comprises for this purpose a cavity for attachment of this seal.

[0019] In order to place the framed window the window is placed from outside in wall opening 5, wherein a flanged edge of the casing frame will drop over the edge part of wall 10 adjacent to opening 5. Provided beforehand therebetween is the adhesive bead which will already ensure a certain adhesion to wall 10, whereby the window remains in position in wall opening 5. The casing frame comprises all around on the periphery fixation means in the form of a series of mounting clamps of the type as further elucidated in a concurrent patent application of applicant.

[0020] In order to be able to close the window if desired, a closure 30 is provided thereon according to the present invention as shown in further detail in FIGS. 2A and 2B. The closure comprises a base part 32 with which the closure is attached directly to the inner pane of the window at a first interface I. The base part is provided for this purpose with bores for receiving corresponding screw members. The closure further comprises a top part 36 from which a handle 34 extends. Handle 34 is connected rigidly here to this top part 36, wherein top part 36 is in turn connected for rotation about a rotation axis III to the base part at a second interface II, see also FIG. 3B.

[0021] The interface I with the inner pane is shown schematically in FIG. 2B. In the closed first position of the closure shown here the handle 34 extends substantially parallel to interface I and handle 34 maintains a distance d1 relative to the interface, and thereby the inner pane. A protrusion 35 likewise formed on top part 35 closes here behind a shoulder (not further shown) extending from the inner edge of casing frame 20 so that in this situation the window cannot be opened and remains closed. In order to open the window the handle is pivoted upward, see FIG. 3A, whereby protrusion 35 is disengaged from the shoulder and the window is thereby released. The handle now points upward in the direction of the hinge side of the window with hinge 24.

[0022] As further shown in FIG. 3B, second interface II makes an acute angle with first interface I. In other words, pivot axis III thus lies obliquely of first interface I at an obtuse angle which is complementary to the angle between the two interfaces (i.e. s=90+). Because of this oblique position of pivot axis III the handle 34 also lies at this angle to window I in the wholly upright position, see FIG. 3B, and handle 34 moves away from the window when the closure is opened. In the situation shown in FIGS. 3A and 3B the handle hereby maintains a distance d2 from the window which is significantly greater than the original intermediate space d1. The handle hereby now provides considerably more grip, while in the closed position the handle can lie relatively closely against the window. Closure 30 hereby does not protrude relatively very far inward in the closed position.

[0023] Although the invention has been further elucidated above with reference to 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 within the scope of the invention for a person with ordinary skill in the art.
