DETAILED DESCRIPTION

[0059] FIG. 1 shows a schematic representation of a cross section of an example of a combination 1 of a window frame 2 and a window covering assembly 4 according to the invention. The combination 1 in FIG. 1 is mounted to a wall 6. The wall 6 has an opening 8 in which the window pane 10 extends. The window pane 10 is mounted in the window frame 2. It will be appreciated that the window frame 2 may be provided with a structure for allowing the window to be opened.

[0060] In this example, the window frame 2 includes a first frame member 12 of an extruded profile, e.g. of plastics or aluminum. The first frame member 12 has a flange 14 that abuts against a first side 16 of the wall 6. In this example, the first side 16 is the outer side of the wall, e.g. the outside of a recreational vehicle. In FIG. 1 the window frame 2 further includes a mounting bracket 18. The mounting bracket 18 has a flange 20 that abuts against a second side 22 of the wall 6. Here the second side 22 is opposite the first side 16. In this example the mounting bracket 18 is mounted to the first frame member 12 using a screw 24.

[0061] FIG. 2A shows an example of a window covering assembly 4. In FIG. 2A the window covering assembly is shown as viewed in the direction of arrow A in FIG. 1. In this example the window covering assembly 4 includes an assembly frame 26. Here the assembly frame 26 includes four second frame members 28. The second frame members 28 are extruded profiles, e.g. of plastics or aluminum. In this example the second frame members 28 are mutually connected via corner pieces 30. The window covering assembly 4 further includes a movable beam 32. The movable beam is movable with respect to the assembly frame 26. In this example the left and right second frame members act as guides for guiding movement of the movable beam 32 in the direction of arrows B1 and B2. The window covering assembly 4 further includes a screen 34. The screen 34 is connected to the movable beam at a first side 36 thereof. The screen is connected to the assembly frame 26 at a first side 38 thereof. In this example the screen 34 includes a mounting strip 37 that is inserted into a mounting groove 39 of the second frame member 28. When the movable beam 32 is moved in the direction of arrow B1 the screen 34 is extended over the window opening. Thus, the screen closes off the window opening. When the movable beam 32 is positioned adjacent a second side 40 of the assembly frame 26 the window opening is fully closed by the screen 34, and the movable beam is said to be in the closed position. When the movable beam 32 is moved in the direction of arrow B2 the screen 34 is compacted. In this example the screen 34 is pleated, so as to be compacted by folding. It is also possible that the screen is wound up on a roll for compacting the screen. When the movable beam 32 is positioned adjacent the first side 38 of the assembly frame 26 the window opening is fully released by the screen 34, and the movable beam is said to be in the open position. In this example the window covering assembly 4 includes a brush strip 41. The brush strip 41 presses against the screen 34 when compacted for preventing movement of the screen 34. This helps prevent rattling of the screen.

[0062] In this example the window covering assembly 4 includes two opposed guides 27 for guiding the movable beam 32. The opposed guides 27 allow for sliding movement of the movable beam 32. In this example the window covering assembly 4 also includes cords. The cords extend through the movable beam 32 in a so-called H-configuration. A first cord 29 extends from the top left corner of the window covering assembly 4 to the left of the movable beam 32, through the movable beam to the right of the movable beam, and from the right of the movable beam 32 to the lower right corner of the window covering assembly 4. A second cord 31 extends from the bottom left corner of the window covering assembly 4 to the left of the movable beam 32, through the movable beam to the right of the movable beam, and from the right of the movable beam 32 to the upper right corner of the window covering assembly 4. The cords 29, 31 in the H-configuration aid in maintaining the movable beam 32 aligned orthogonal to the opposed guides 27.

[0063] It will be appreciated that the window covering assembly 4 may also include a second movable beam 32A as shown in FIG. 2B. The second movable beam, may e.g. be connected to a shade 34A at a second side 36A of the second movable beam 32A. The shade 34A may be connected to the assembly frame 26 at a second side 40 thereof. The second movable beam may also have associated cords in a H-configuration. When the second movable beam 32A is moved in the direction of arrow B1A the shade 34A is compacted. In this example the shade 34A is pleated, so as to be compacted by folding. It is also possible that the shade is wound up on a roll for compacting the shade. When the second movable beam 32A is positioned adjacent the second side 40 of the assembly frame 26 the window opening is fully released by the shade 34A, and the second movable beam is said to be in the open position. It will be appreciated that using both the movable beam 32 and the second movable beam 32A any combination of the window being (partly) uncovered, (partly) covered by the screen 34 and/or (partly) covered by the shade 34A can be obtained.

[0064] Turning again to FIG. 1, the second frame member 28 of the window covering assembly 4 is also shown. In FIG. 1 the window covering assembly 4 is attached to the window frame 2 by means of a snap element 42. In this example the snap element 42 is a separate element. The snap element 42 may e.g. be an injection moulded part, e.g. of a plastics material.

[0065] The snap element 42 in FIG. 1 has a first lug 44 engaging with the window frame 2. The snap element in FIG. 1 has two second lugs 46 engaging with the window covering assembly 4.

[0066] The window frame 2, here the first frame member 12, has a first groove 48. The first groove 48 has a depth direction in a direction substantially orthogonal to the plane of the window pane 10. It will be appreciated that it is also possible that the first groove 48 has a depth direction in a direction substantially orthogonal to the plane in which the wall 6 extends. Normally the window pane 10 and the wall 6 will extend in parallel planes. In the example the first groove 48 is an extruded groove in the extruded profile forming the first frame member 12. The first groove 48 includes an undercut portion 50. The first lug 44 of the snap element 42 has a projection 52 engaging with the undercut portion 50. The projection 52 and the undercut portion 50 ensure a proper snap fit of the snap element 42 in the first groove 48. Unintentional removal of the snap element may thereby be prevented. In this example, the undercut portion has a retaining surface 54 extending substantially orthogonal to the depth direction of the first groove 48. Also the projection 52 has a retaining surface 56 extending substantially orthogonal to the direction in which the first lug 44 extends i.e. substantially orthogonal to the depth direction of the first groove 48. The retaining surfaces 54, 56 ensure a high force barrier against removal of the snap element 42 from the first groove 48.

[0067] In this example the first groove 48 has one surface provided with longitudinally extending ridges 49. These ridges are preferably dimensioned not to interfere with positioning accuracy provided by the interaction between the projection 52 and the undercut portion 50. The longitudinal ridges 49 provide a serrated surface that the screw 24 securing the mounting bracket 18 to the first frame member 12 can grip to.

[0068] The window covering assembly 4, here the second frame member 28, has a second groove 58. The second groove 58 has a depth direction in a direction substantially orthogonal to the plane of the window pane 10. It will be appreciated that it is also possible that the second groove 58 has a depth direction in a direction substantially orthogonal to the plane in which the window covering extends. Normally the window pane 10 and the window covering will extend in parallel planes. In the example the second groove 58 is an extruded groove in the extruded profile forming the second frame member 28. In this example the second groove 58 is much wider than the first groove 48. The second groove 58 has a width that is preferably more than two times, more preferably more than four times, even more preferably more than eight times the width of the first groove 48. This allows the second groove 58 to be engaged by two second lugs 46 of the snap element 42. Said two second lugs 46 are laterally spaced apart, i.e. in a direction orthogonal to the longitudinal direction of the second groove 58. Thus, the snap element 42 engages the first and second frame members 12, 28 at three point when viewed in the lateral cross section of FIG. 1. This three-point connection makes for a very stiff and dimensionally stable connection between the window covering assembly 4 and the window frame 2.

[0069] The second groove 58 includes undercut portions 60. The second lugs 46 of the snap element 42 each have a projection 62 engaging with the respective undercut portion 60. The projections 62 and the undercut portions 60 ensure a proper snap fit of the snap element 42 in the second groove 58. Unintentional removal of the snap element may thereby be prevented. In this example, the undercut portions each have a retaining surface 64 extending substantially orthogonal to the depth direction of the second groove 58. Also the projections 62 each have a retaining surface 66 extending substantially orthogonal to the direction in which the second lugs 46 extend i.e. substantially orthogonal to the depth direction of the second groove 58. The retaining surfaces 64, 66 ensure a high force barrier against removal of the snap element 42 from the second groove 58. In this example the second frame member 28 includes a hollow extrusion portion 29. The hollow extrusion portion 29 provides extra stiffness to the undercut portion 60.

[0070] In this example the snap element 42 includes a first support surface 57 for abutting against the first frame member 12. This provides the advantage that forces exerted onto the window frame 2 or onto the window covering assembly 4 can be transmitted more efficiently, reducing the risk of material failure of the snap element 42. Here, the projection 52 and the first support surface 57 are positioned and dimensioned for applying substantially oppositely directed forces onto the first frame member 12. This provides the advantage that the connection between the snap element 42 and the first frame member 12 has no play. Any potential play is counteracted by the opposed forces.

[0071] In this example the snap element 42 includes a second support surface 67 for abutting against the second frame member 28. This provides the advantage that forces exerted onto the window frame 2 or onto the window covering assembly 4 can be transmitted more efficiently, reducing the risk of material failure of the snap element 42. Here, the projection 62 and the second support surface 67 are positioned and dimensioned for applying substantially oppositely directed forces onto the second frame member 28. This provides the advantage that the connection between the snap element 42 and the second frame member 28 has no play. Any potential play is counteracted by the opposed forces.

[0072] For assembling the window covering assembly 4 to the window frame 2, a plurality of snap elements 42 may be snap fitted to the window covering assembly 4. Next, the window covering assembly 4 with the snap elements can be snap fitted to the window frame 2 by inserting the first lugs 44 into the first grooves 48. This snap-fitting can be done in a direction substantially orthogonal to the plane in which the window pane extends. This provides the advantage that snap-fitting the window covering assembly 4 to the window frame 2 is very intuitive and alignment is very easy. As can be seen in FIG. 1, the first groove 48 is provided with a tapered entrance area 51. The tapered entrance area 51 aids in inserting the first lugs 44 into the first groove 48, especially since a view of the first groove 48 may be, at least partially, obstructed when snapping the window covering assembly 4 onto the window frame 2.

[0073] FIG. 3 shows a schematic view of a window covering assembly 4 attached to a window frame 2. In this example the upper second groove 58 is connected to the upper first groove 48 by means of three snap elements 42. In this example the lower second groove 58 is connected to the lower first groove 48 by means of three snap elements 42. In this example the left second groove 58 is connected to the left first groove 48 by means of two snap elements 42. In this example the right second groove 58 is connected to the right first groove 48 by means of two snap elements 42. It will be appreciated that different numbers of snap elements 42 may be used, e.g. depending on dimensions of the window covering assembly 4. It is possible that not each first frame member 12 is connected to a second frame member 28.

[0074] FIGS. 4A and 4B show schematic cross sectional views demonstrating an example of adaption of the system to different wall thicknesses. In FIG. 4A the wall 6 has a first thickness and the length L of the snap element 42 is chosen according to the first wall thickness. In FIG. 4B the wall 6 has a second thickness and the length L of the snap element 42 is chosen according to the second wall thickness. It will be appreciated that a mounting kit for mounting the window covering assembly 4 to the window frame 2 may include a first plurality of snap elements 42 of a first length and a second plurality of snap elements 42 of a second length, so as to allow a user to select the snap elements 42 appropriate for the wall thickness at hand. It will be appreciated that it is also possible that more than two different lengths are provided.

[0075] FIG. 5 shows a schematic cross sectional view wherein an alternative snap element 42A is shown. The alternative snap element 42 is arranged to be flexible in the lateral direction. Here the alternative snap element has a flexible lip 43, acting as a leaf spring. Hence, the first lug 44 can move laterally relative to the second lugs 46. Since the flexible lip acts as a leaf spring, stiffness in the longitudinal direction is not compromised. Advantageously, the window covering assembly 4 is attached to the window frame 2 using one or more snap elements 42, which accurately define positioning of the window covering assembly 4 relative to the window frame, and using one or more alternative snap elements 42A, which allow to accommodate dimensional tolerances or misalignment of first frame members relative to second frame members.

[0076] FIG. 6 shows a schematic cross sectional view of a combination of a window covering assembly 4 and a window frame 2. The combination is similar to the combination shown in FIG. 1. In the example of FIG. 6 the window covering assembly 4 further includes a first trim plate 68 for covering the gap between the window covering assembly 4 and the window frame 2 on the inner perimeter. The first trim plate 68 inserts into a further groove 70 of the second frame member 28. In the example of FIG. 6 the window covering assembly 4 further includes a second trim plate 69 for covering the gap between the window covering assembly 4 and the wall 6 on the outer perimeter. The second trim plate 69 inserts into a further groove 71 of the second frame member 28. In FIG. 6 the window covering assembly further includes an outer cover 72. The outer cover 72 can be a decorative cover covering the first frame member 28. In this example the outer cover has a hook portion 73 and a retaining portion 75 for snap-fitting the outer cover 72 to the second frame member 28. In FIG. 6 the window covering assembly further includes an outer corner cover 74. The outer corner cover 74 can be a decorative cover covering the corner piece 30. In this example, the window covering assembly 4 further includes a roundover insert 76 at the corner.

[0077] Returning to FIG. 1, in this example the window covering assembly 4 includes a lighting unit 78. In this example the lighting unit is arranged as a plate wit light emitting diodes (LEDs) 80 mounted on a surface thereof. The lighting unit 78 here is arranged to transmit light in a main direction substantially parallel to the wall. This provides indirect illumination of a room including the window, which often is experienced as pleasing. Direct view of the LEDs 80 can be obstructed by the outer cover 72.

[0078] Herein, the invention is described with reference to specific examples of embodiments of the invention. It will, however, be evident that various modifications and changes may be made therein, without departing from the essence of the invention. For the purpose of clarity and a concise description features are described herein as part of the same or separate embodiments, however, alternative embodiments having combinations of all or some of the features described in these separate embodiments are also envisaged.

[0079] In the examples, the window frame and the window covering frame are substantially rectangular. However, it is also possible that one or more of the first and/or second frame members is slanted. It is also possible that one or more of the first and/or second frame members is curved.

[0080] In the example of FIG. 2B two movable beams are used. It is also possible that a single movable beam is used having the screen attached to a first side thereof and the shade attached to a second side thereof. Further, in the examples of FIGS. 2A and 2B the window covering assembly includes a screen and a shade. It is also possible that the window covering assembly includes two screens or two shades. The two screens can e.g. have a different mesh size, transparency, translucency, color, pattern or texture. The two shades can e.g. have a different transparency, translucency, color, pattern or texture.

[0081] In the examples the movable beam is arranged for movement in vertical direction. It will be appreciated that it is also possible that the movable beam is arranged for movement in other directions, such as horizontal direction.

[0082] However, other modifications, variations, and alternatives are also possible. The specifications, drawings and examples are, accordingly, to be regarded in an illustrative sense rather than in a restrictive sense.
