Window device, method for manufacturing such a window device and method for connecting a translucent element to a flat roof

The invention relates to a window device. The invention also relates to a method for 5 manufacturing such a window device. The invention further relates to a method for connecting a translucent element to a flat roof.

Window devices are used for closing openings in walls, roofs and the like and for providing light from outside into buildings. The known window device typically 10 comprises a translucent element, and a circumferential body for supporting the translucent element and connecting it to a substrate, such as a wall or roof. When a window device is applied onto a roof, the window device, and in particular the translucent element thereof, may become dirty as a result of (a combination of) rain, wind, sand, leaves etc. This particularly holds when the window device is connected to 15 a flat roof. As a result, increased maintenance of the window device is needed. Moreover, the lifetime of the window device may decrease as a result of material deterioration. Also, the collected dirt may decrease the translucency of the window device.

20 To overcome the mentioned problems, the known window device typically comprises a dome-shaped translucent element. Dirt is less likely to collect onto a dome-shaped window, since it falls off. However, due to its shape, the translucent element of such skylights typically comprises a single layer of a translucent plastic, such as polycarbonate. A disadvantage of the known window device is its inferior thermal 25 insulation. The plastic moreover tends to degrade and is not sufficiently scratch resistant.

It is an object of the invention therefore to provide a window device, which overcomes at least some of the abovementioned problems of the known window device. It is also 30 an object to provide a method, which allows for easy manufacturing of such a window device. It is a further object to provide a method for connecting a translucent element to a flat roof.

2

These and other objects are achieved according to the invention by providing a window device, comprising a substantially flat translucent element, and a circumferential body for supporting and connecting the translucent element to a substrate, wherein the circumferential body is adapted for connecting the translucent element to the substrate 5 such that the translucent element makes an angle with the substrate. By connecting the substantially flat translucent element with the substrate under an angle with the substrate, a preferred orientation of the translucent element can be chosen, preferably under an angle with the horizontal, such that dirt on the translucent element, for example as a result of rain, wind, sand etc., will be forced downward and away from the 10 translucent element by gravity.

The window device is particularly suitable to be connected to a substrate, which substantially extends in horizontal direction. As the window device comprises the circumferential body of the invention, it may readily be connected to a substrate under 15 an angle, the angle being defined a priori for best performance. The substantially flat translucent element will make a well defined angle with the horizontal and any dirt will be forced downward by gravity. As a result the translucent element will remain translucent for a longer period and maintenance only needs to be done at longer time intervals. The window device according to the invention is also advantageously suitable 20 for connecting to a flat roof. Typically a flat roof is difficult to reach, while it is a favourable location to position a translucent element, to allow light to enter a building.

An additional advantage of the window device according to the invention is that it allows for easy positioning the window device onto a flat roof, wherein the substantially 25 flat translucent element has a preferred angle with the horizontal. Therefore the invention also provides a method for connecting a translucent element to a substantially flat roof, wherein the translucent elements makes an angle with the flat roof, comprising providing a window device according to the invention and connecting the window device to the flat roof using connecting means. As a result, builders, such as carpenters 30 do not need to adjust known circumferential bodies to position a substantially flat translucent element onto a flat roof with a preferred angle with the horizontal. Even for experienced builders it is difficult to adjust a known circumferential body such that the translucent element when positioned onto a flat roof makes a preferred angle with the horizontal. Using the window device according to the invention allows for easy 3 installing a window device, whereby the substantially flat translucent element makes a preferred angle with the horizontal, without extensive measuring and adjusting the circumferential body.

5 In a practical embodiment the circumferential body comprises an upper surface at the side of the translucent element and a lower surface at the opposite side, wherein the upper surface makes an angle with the lower surface. Such a circumferential body and window device is readily manufactured.

10 The angle between the upper surface and the lower surface of the circumferential body may vary within wide ranges. Preferably, the angle between the upper surface and the lower surface of the circumferential body is less than 15°, more preferably less than 10° and most preferably between 1° and 6°. These angles combine good removal of dirt and discharge of water with a limited height and weight of the window device and thereby 15 allowable aesthetics for the user of the window device. Especially an angle of between 1° and 6° will give the impression of a horizontal surface, which is desirable from an aesthetic point of view, yet it hinders accumulation of dirt, which may not be so in case of a real horizontal surface.

20 In another preferred embodiment, the circumferential body is made from at least one profiled element, wherein the height of at least a part of the at least one profiled element tapers for obtaining the angle between the upper surface and the lower surface of the circumferential body. Using a tapered profiled element not only allows for obtaining an accurate angle between the upper surface and the lower surface of the circumferential 25 body, but it also provides a good fit between the translucent element and the circumferential body.

The circumferential body may have various shapes, such as a circular or triangular shape, particularly to adjust or replace existing windows. Preferably, the circumferential 30 body encloses a rectangle, wherein first mutually parallel extending profiled elements have a mutually differing height, which first profiled elements are connected by second profiled elements, which second profiled elements extend perpendicular to the first profiled elements, wherein the height of the second profiled elements taper between the heights of the first profiled elements. As existing windows are typically rectangular 4 shaped, the window device according to the invention can advantageously be used to replace or adjust existing windows, such as light domes positioned on roofs.

The circumferential body may be manufactured from various materials, such as metals, 5 plastics or even composites. Preferably, the circumferential body is substantially manufactured from a material selected from the group consisting of aluminium, ABS, polyolefins, polyvinyl chloride and wood. Such materials combine strength, weather resistance and easy manufacturing of the circumferential body. Preferably the circumferential body is made from polyvinyl chloride. A typical manufacturing method 10 comprises extruding first and/or second profiled elements and assembling these into a frame or circumferential body by mutually connecting the ends of the profiled elements. Connecting the elements can be carried out in a number of ways, known per se, for instance by mechanical means, such as screwing, entrapping, clamping, or by adhesive means, such as gluing or welding.

15

In another embodiment the window device comprises a frame for holding the translucent element. This allows for improved connecting the translucent element to the circumferential body, particularly if the translucent element is made from a material, which is difficult to process such as brittle materials like glass. Preferably but not 20 necessarily, the translucent element and the frame both comprise an upper surface, which coincide when the frame holds the translucent element. This results in improved aesthetics and allows for good closing of the translucent element within the frame. Between the translucent element and the frame an opening may be located, which may be filled with an elastic material, preferably a rubber or a sealant.

25

The translucent element may be rigidly connected to the circumferential body. In a preferred embodiment, the translucent element is movably connected to the circumferential body, between a first position wherein the window device is closed and a second position wherein the window device is opened. This allows for opening the 30 window device for ventilation, cleaning of the window device, etcetera. The translucent element may be glidingly connected to guides fixed to the circumferential body. The translucent element may also be hingedly connected to the circumferential body. Preferably the window device according to the invention comprises driving means, such as an electromotor combined with a chain connected to the translucent element, for 5 driving the translucent element. The driving means may be positioned at various locations. Preferably, the driving means substantially extend within the circumferential body.

5 In another preferred embodiment the frame comprises a projection at the side of the circumferential body, which projection extends beyond the outer circumference of the circumferential body and the upper surface of the circumferential body. The projection prevents dirt and water from entering the space below the window device, particularly a building, via the transition between the translucent element and the circumferential 10 body. Preferably the projection extends substantially along the circumference of the translucent element, which improves the closing between the translucent element and the circumferential body.

The translucent element may be made from various materials, such as from plastics, like 15 polymethylmethacrylate (PMMA) and/or polycarbonate, and/or glass. Preferably, the translucent element comprises a composition of at least two plates,, positioned at some distance from each other, between which plates a gas is located. The plates may be manufactured from plastics. Preferably, the plates are manufactured from glass. The combination of the circumferential body with such a substantially flat translucent 20 element is very advantageous, as it shows good sound and thermal insulation as well as prevention of burglary and in addition allows for easy positioning onto a substrate such as a flat roof.

In another embodiment the window device is characterized in that the circumferential 25 body is connectable to a supporting structure for connecting the translucent element at a distance from the substrate. This prevents entering dirt and water from entering the building. Commonly, the supporting structure is connected to the substrate beforehand or is part of the substrate, for example in case of flat roofs. The window device according to the invention allows for easy positioning the window device onto the 30 supporting structure. The supporting structure comprises a through opening, which opening at the side to which the supporting structure is connectable to the circumferential body preferably passes over in the opening formed by the circumferential body. The invention also provides a method for connecting a translucent 6 element to a flat roof, wherein the window device is connected to the roof by a supporting structure. This method allows for easy adjusting existing window devices.

In yet another embodiment, the supporting structure comprises an upper surface at the 5 side of which the supporting structure is connectable to the circumferential body wherein the circumferential body comprises a projection at the side to which the circumferential body is connectable to the supporting structure, which projection extends beyond the outer circumference of the supporting structure and the upper surface of the supporting structure. The projection prevents dirt and water from entering 10 the building via the transition between the circumferential body and the supporting structure. Preferably the projection extends substantially along the circumference of the circumferential body, which improves the closing between the circumferential body and the supporting structure.

15 In a preferred embodiment of the invention a support structure for the window device, or for any known window device, such as a light dome, is provided. The support structure of the invention comprises a circumferential body of wall elements, which wall elements comprise relatively small and large cavities. The cavities provide the wall elements with stiffness and good insulation properties. The small cavities are preferably 20 filled with additional stiffening strips. The larger cavities are preferably filled with relatively large blocks of insulation material, such as polystyrene or polyurethane foam blocks. Using relatively large blocks of insulation material improves the thermal insulation of the support structure, as compared to an alternative embodiment that uses polystyrene foam granules.

25

Preferably an upper relatively large cavity is filled with driving means, adapted to drive a translucent element between an opened and a closed position. A lower cavity comprises an insulation block made from polystyrene foam. The support structure further comprises base wall elements to position and fix the structure to a substrate such 30 as a roof. The base wall elements preferably extend at the outer circumference of the supporting structure. This allows to easily fix the supporting structure to a substrate, such as a flat roof, using fixing means such as bolts or screws.

7

Accurate manufacturing a circumferential body with a preferred angle between the upper and lower surface of the circumferential body is difficult. The invention therefore also provides a method for manufacturing a window device according to the invention, comprising: building the circumferential body from at least one profiled element, at 5 least temporarily fixing the built circumferential body in a frame, fixing the frame provided with the fixed circumferential body at a preferred angle relative to removing means, and removing material from the circumferential body such that the upper surface of the circumferential body makes an angle with the lower surface of the circumferential body. This method allows for easy manufacturing of a circumferential body according 10 to the invention. Particularly, the preferred angle corresponds to the angle between the upper surface and the lower surface of the circumferential body. Alternatively, the method may comprise at least temporarily fixing at least one profiled element in a frame, fixing the frame provided with the fixed at least one profiled element at a preferred angle relative to removing means, removing material from the profiled 15 elements, building the circumferential body from the thus shaped profiled elements, wherein the material is removed from the profiled elements such that the upper surface of the built circumferential body makes an angle with the lower surface of the circumferential body.

20 In a preferred embodiment the material is removed by machining means, which substantially extend in horizontal direction. This allows for easy setting of the machining means. Preferably the machining means comprise a band saw, a circle saw or mill, which extend in horizontal direction. This allows for accurate setting of the removal means and for easy handling for the user.

The invention will now be described in more detail, by way of example, with reference to the accompanying figures, in which: figure 1 shows a perspective bottom view on a window device according to the invention; 30 figure 2a shows a top-view of the window device of figure 1; figure 2b shows a frontal-view of the window device of figure 1; figure 2c shows a side-view of the window device of figure 1; figure 3 shows a cross-section of an embodiment of a window device according to the invention; and 8 figure 4 shows a cross-section of a profiled element of a supporting structure according to the invention.

With reference to figure 1, a perspective view on a window device 1 is shown. The 5 window device 1 comprises a substantially flat translucent element 2, made from a composition of two glass plates positioned at some distance from each other, between which glass plates a gas is located. The translucent element 2 is connected to a frame 3. The frame 3 comprises an inner wall and in thermal insulation therewith an outer wall (not shown). The frame 3 comprises a lower surface 3a. The frame 3 with the 10 translucent element 2 is supported by a circumferential body 4, which is built from profiled elements (4a,·4b,·4c,4d). The profiled elements 4b and 4d extend in a first parallel direction and the profiled elements (4a,4c) extend in a second parallel direction, perpendicular to the first direction. The profiled elements (4a, 4b, 4c, 4d) are preferably made from polyvinyl chloride extruded foam.

15

As a result the profiled elements (4a,4b,4c,4d) enclose a rectangular opening 5. The profiled element 4b has a height hi, and the profiled element 4d has a height h2, wherein hl<h2. The profiled elements 4a,4c are tapered, from the height hi to the height h2. The circumferential body 4 comprises an upper surface 4e and a lower 20 surface 4f. Due to the tapering of the profiled elements (4a,4c), the upper surface 4e makes an angle with the lower surface 4f. The circumferential body 4 supports the translucent element 2 at the lower surface 3 a of the frame 3 by the upper surface 4e of the circumferential body 4. As a result, the flat translucent element makes an angle with the lower surface 4f of the circumferential body 4. The translucent element 2 and the 25 circumferential body 4 are supported by a supporting structure 6. The supporting structure 6 comprises a lower surface 6a and an upper surface 6b, which upper surface 6b coincides with the lower surface 4f of the circumferential body 4. The lower surface 6a of the supporting structure 6 is connected to a flat roof (not shown). Figures 2a,2b,2c show a top-view, a frontal view and a side view of the window device 1 of figure 1, 30 respectively.

With reference to figure 3, a cross section of a window device 100 according to an embodiment of the invention is shown. The window device 100 comprises a translucent element 101, which is made from a composition of two glass plates 102, positioned at 9 some distance from each other by spacers 103, between which glass plates 102 a gas is located. The translucent element 101 is rigidly fixed to a frame 104. Between the translucent element 101 and the frame 104 a sealant 105 is positioned, which results in a medium tight connection between the translucent element 101 and the frame 104. The 5 frame 104 comprises protrusions 106, which extend in downward direction and form cavities 107. The translucent element 101 and the frame 104 are hingedly connected to a circumferential body 110 by a hinge 111. The translucent element 101 can be moved with respect to the circumferential body 110 between a closed position and an opened position (opened position is shown in figure 3). The protrusions 106 are positioned such 10 that the circumferential body 110 is taken up in the cavities 107 if the translucent element 101 is in a closed position. As a result, dirt and water are prevented from entering through the transition between the translucent element 101 and the circumferential body 110.The circumferential body 110 is built up from profiled elements (112a,112b,112c,112d). Only profiled elements 112b and 112d are shown, of 15 which profiled element 112b has a first height hi and profiled element 112d has a height h2, wherein hl<h2. The circumferential body has a lower surface 110a and an upper surface 110b. When the translucent element 101 is in a closed position, it rests on the upper surface 110b of the circumferential body 110. As a result, when the translucent element 101 is in a closed position, it makes an angle with the lower surface 20 110a of the circumferential body 110. As the lower surface 110a of the circumferential body 110 extends in a horizontal direction, the translucent element 101 makes an angle with the horizontal in a closed position. Opposite to the hinge connection between the frame 104 and the circumferential body 110, the frame 104 and the circumferential body 110 are connected by a chain-motor 113, which is known per se, which drives the 25 frame between closed and opened positions. Therefore, a chain 113a is connected to the frame 104 at a first end and to the house 113b of the chain-motor 113 at a second end. The house 113b is taken up in a cavity within the profiled element 112b. The circumferential body 110 comprises protrusions 114, which extend in downward direction. The circumferential body 110 is connected near its lower surface 110a to a 30 supporting structure 120 near an upper surface 120a of the supporting structure 120 by bolts (not shown). The protrusions 114 extend beyond the upper surface 120a of the supporting structure 120. As a result, dirt and water are prevented from entering through the transition between the circumferential body 110 and supporting structure 120. The 10 supporting structure may for example be connected to a flat roof of a building (not shown).

With reference to figure 4, a cross-section of a profiled element 140 of a support 5 structure according to the invention is shown. The profiled elements 140 form a circumferential body. The profiled element 140 comprises multiple wall elements 141 made from polyvinyl chloride, which wall elements comprise relatively small cavities 141a, which provide the wall elements 141 with stiffness and good insulation properties. The wall elements 141 further enclose relatively large cavities 142 (relative 10 to the small cavities 141a) within the profiled element 140. The small cavities 141a are filled with stiffening strips 143. An upper large cavity 142 is filled with driving means 145, adapted to drive a translucent element between an opened and a closed position (not shown). A lower relatively large cavity 142 comprises an insulation block 146 made from polystyrene foam. Instead of polystyrene foam, also other materials may be 15 used, such as polyurethane foam. The profiled element 140 further comprises base wall elements 147, 148, which extend at the outer circumference of the supporting structure, for fixing the supporting structure to a substrate, such as a flat roof, using fixing means such as bolts or screws.
