Definitions
- the present invention relates to a window system
- a window system comprising a window including a frame and a sash, each having a plurality of members defining a frame and a sash plane, respectively, said sash (3; 103) being connected to the frame by means of at least one hinge connection, so that the sash can be moved from a closed position to an open position, and into an intermediate ventilating position, in which ventilating position the sash plane forms an angle within a limited angle range with the frame plane to provide at least one ventilating aperture in the circumferential of the frame and/or sash, and said window system further comprising a screening arrangement arranged to cover the said ventilating aperture in the ventilating position.
- window system including windows with a ventilating position, in order to provide easy ventilation of a room without the need to fully open the window.
- the windows thus have a ventilating aperture, through which not only air can flow, but also objects, such as insects, may enter.
- objects such as insects
- block the entry of objects through the ventilating aperture by providing the windows with a screening arrangement.
- Screening arrangements in such window systems are generally provided in the form of a screening curtain, netting or similar attached to either the frame or sash, or, in an activated screening position, to both the frame and sash, so that they can be manually activated by a user handling the screening arrangement after opening of the window or is automatically activated throughout the entire opening movement of the window, i.e. following the path of opening of the window so as to cover the full aperture provided in an open position of the window.
- a screening arrangement of this kind is known from Applicant's application no. WO2005/005762 A1 , which discloses a pivotal roof window having a screening arrangement arranged to provide screening of the top and/or bottom part of the window exclusively.
- the screening arrangement is moved automatically from an inactive position corresponding to the closed position of the window to an active position corresponding to the ventilating position, and from the active position to the inactive position when the window is brought from its ventilating position to its closed position.
- the screening arrangement is for example formed as an element hanging freely form the top and/or bottom member or as a curtain being connected to the top and bottom member of the frame and sash. Such screening arrangements are thus useful in the sense that they block out incoming objects in the top and/or bottom of the window effectively.
- screening arrangements must however be formed as an element hanging freely from either the frame and/or sash or being connected to both the frame and sash in order to cover at least the bottom aperture in the ventilating position, which may create an unwanted direct visible and to some degree aesthetically unpleasing screening arrangement.
- the screening arrangement has the form of a curtain covering the aperture between the sides, top and bottom members of the window in the open position.
- US patent no. 1,997,206 discloses a solution where a screen is provided between the lower edge of the window sash and the forward edge portion of the sill, where the outer edge of the screen is inserted in a recess provided along the inner side of the lower portion of the sash.
- This solution for screening off especially the sides of the window is useful in the sense that it blocks out incoming objects such as insects, while providing a ventilating passage of the window both in an open position and a ventilating position of the window.
- a roof window generally designed especially to facilitate easy window cleaning as the sash comprising the pane can be turned essentially 180° to allow cleaning of the outside surface of the pane from inside the building, with such screening arrangements you must remember that they have to be decoupled from the frame and/or sash in order to make the 180° rotation.
- the large screening arrangement constituted by the prior art can be aesthetically unpleasing, as the screening arrangements are blocking at least portions of the view through the window.
- the screening arrangement is clearly visible, when the window is closed, which makes these solutions less advantageous.
- a window system according to claim 1.
- the screening arrangement as a screening element in the frame and/or sash members of the frame and/or sash itself, a simple and uncomplicated ventilating facility is achieved. Positioning the window in the ventilating position automatically provides screening of the ventilating aperture while at the same time allowing the air to pass by the first and second set of openings.
- said at least one screening element including the ventilating passage is formed in a profile element having at least two adjacent sides of which the one side faces an interior or inner side of the window and constitutes said first face and the other side faces an exterior or outer side of the window and constitutes said second face.
- the profile element includes a cavity configured to allow air flow between the first set of openings and the second set of openings and vice versa. This configuration allows optimum utilization of the space available and increases the manufacturing efficiency even further.
- the first set of openings may either be contiguous with the second set of openings, or, alternatively, a transition portion may be provided between the first face and the second face to separate the first set of openings from the second set of openings.
- the ventilating passage is formed in a separate and detachable screening element configured to be connected to said at least one frame and/or sash member in a mounted condition of the window.
- the ventilating passage is formed in the profile element constituting said at least one frame and/or sash member itself. This provides for a completely integrated solution of the screening arrangement in the window system and is particularly advantageous in fields of application allowing the frame and/or sash structure to be formed by profile elements.
- the ventilation passage is provided by openings in the first face of the profile element and openings in the second face connected via a cavity of the profile element, the cavity being separated from other parts of the frame and/or sash member.
- a sealing flange is provided to extend between the sash member and the frame member in the ventilating aperture of the window, such that the sealing flange abuts the transition portion in the ventilating position to allow air passage only via the ventilating passage. This provides for excellent control of the ventilating properties.
- the window 1 comprises a frame 2 and a sash 3, and a hinge connection (not shown) providing a hinge axis allowing the sash 3 to rotate about the hinge axis.
- the frame 2 has a bottom member 4, a top member 6, and two side members 8 and 10.
- the sash 3 is provided with a bottom member 5, a top member 7, and two side members 9 and 11.
- the window 1 is a top-hung roof window having a position of the hinge axis near the top members 6; 7 of the frame 2 and sash 3, but the inventive concept is applicable also to centre-hung or traditional pivot windows having a hinge axis provided near a position halfway between the top and bottom members, just as a position of the hinge axis between the top and centre of the window is also possible.
- the hinge axis is thus substantially parallel with the top members 6; 7 of the frame 2 and sash 3, respectively.
- the window is adapted to be moved between at least three positions, namely a first closed position, where the plane formed by the sash 3 is substantially parallel with the plane formed by the frame 2, a second and ventilating position, where the plane of the sash 3 forms a predetermined angle with the plane of the frame, and a third and open position, where the sash plane forms an angle, larger than the angle in the ventilating position, with the frame plane.
- the sash 3 of the window 1 when in the ventilating position, forms a pre-defined angle with the frame plane and a ventilating aperture 20 is formed in the circumferential of the frame 2 and sash 3.
- the ventilating aperture 20 is at least partly covered by a screening arrangement, as illustrated in Fig. 2 , where the screening arrangement comprises a screening element 21 incorporated in a member of the frame 2.
- the screening arrangement comprises a screening element 21 incorporated in a member of the frame 2.
- Fig. 2 it is only shown how the screening arrangement is incorporated in the frame structure; however it should be noticed that the screening arrangement could be arranged in the sash in a similar manner.
- a screening element is incorporated in each side member 8, 10 of the frame 2, but configurations having a screening element in only one side are conceivable as well, just as a screening element may be incorporated in the bottom member 4 of the frame 2 as well.
- the screening element 21 is as shown in Fig. 2 incorporated in the frame so as to form a ventilating passage 22, and wherein the screening element 21 automatically spans the ventilating aperture 20 between the planes of the sash 3 and frame 2.
- the screening arrangement is arranged in the frame 2, so that it is inconspicuous in both the open and ventilating position of the window 1.
- the term "inconspicuous” is intended to incorporate that the screening arrangement is placed in a way so it appears hidden or inconspicuous for the user's eye in both the open and ventilating position of the window. Furthermore, it is noted that the inconspicuous quality inherently excludes hindrance of the physical access through the opening.
- the inconspicuous characteristics of a first embodiment will be described in further detail in the following.
- the ventilating aperture 20 is covered by a screening arrangement, comprising the screening element 21, which is incorporated into the side members 8 and 10 of the frame.
- the right side i.e. the side of the window to the right side according to the orientation of the drawings, shows the ventilating aperture 20 without the screening element 21 for reasons of clarity.
- the ventilating aperture 20 is shown covered by the screening element 21.
- the screening element 21 is not visible from an interior side of the window, i.e. the screening element is not visible when a person stands in a room and looks at the window, as the side members 9, 11 of the sash cover the screening arrangement in the closed position.
- the screening element or elements are also inconspicuous, since each screening element is incorporated in the members of the frame or sash, in the embodiment shown in the side members 8, 10 of the frame.
- the screening elements 21 do not prevent easy opening of the window to an open position or disturb the functions of the open window, including using this as an emergency exit.
- the function of the ventilating passage 22 created by the ventilating arrangement, comprising the screening element 21 is especially useful, when the window 1 is in the predetermined ventilating position, where it covers the ventilating aperture and thus blocks the entry of objects, such as insects or similar.
- the ventilating passage could be formed by incorporating the screening element in the side members of the sash instead of the side members of the frame, possibly in combination. Furthermore, it would be possible to provide a similar solution of the previously described, wherein the ventilating passage 22 is formed by incorporating the screening element 21 in at least one of the bottom members of the frame and/or sash.
- the ventilating passage 22 is formed to extend only a portion of the side members 8, 10 of the frame, as the screening element 21 is only perforated in a portion of its length.
- the length of extension of the ventilating passage 22 in the side members 8, 10 is chosen in accordance with the length of the screening element 21, which in turn is dependent on the desired amount of ventilation.
- the ventilating passage 22 of the screening element 21 is incorporated in the bottom portion of the side members 8, 10 of the frame. This is a desired place to incorporate the ventilating passage 22 of the screening element 21 for top-hung windows, but in other cases, such as a centre-hung window, an incorporation of the screening element 21 in the top portion of the side members 8, 10 of the frame is just as desirable.
- By positioning the ventilating passage or passages near the bottom and/or top of the frame side members optimal ventilating conditions are achieved, as opening the sash to a small angle presents a sufficient ventilating passage at a distance from the hinge axis.
- the bottom portions of the chosen members are desired places to incorporate the screening element for a top-hung window, and either the bottom or top portions are desired for non top-hung windows, such as pivotal or centre-hung windows. That is when using the screening element in centre-hung windows it may be desirable to block out entry in both the top and bottom apertures present in a ventilating position of the window.
- the screening element 21 is a detachable screening element 21 and the configuration of the screening element 21 is illustrated in more detail in Fig. 10 and 11 .
- the screening element as being detachable is configured to be connected to the at least one frame member 8, 10 in a mounted condition thereof. This makes the screening element 21 suitable for retrofitting, so that it may be produced in different sizes for fitting into different sized windows.
- engagement means 40 are included in either the side member 8, 10, the bottom member 4 or in the screening element 21 in order to connect with the screening element 21 in a second end 26 of the screening element 21.
- the engagement means 40 of the bottom frame member 4 is, as illustrated in Fig. 9 configured as a groove in an engagement part 41 of the bottom frame member 4.
- the screening element 21 is in Figs 10 and 11 , illustrated as a screening element having the form of an L-shape, with a first flange 23 and a second flange 24, the second flange extending substantially perpendicular to the first flange 23, wherein at least one of the first and/or second flanges 23, 24 comprises the ventilating passage 22.
- the L-shaped screening element 21 is as previous described arranged to be incorporated in at least one of any of the frame and/or sash members 4, 5, 6, 7, 8, 9, 10, 11 in a mounted condition, and extends either over a portion of the member to which it is incorporated in or in the entire length of the member in question.
- the screening element 21 is mounted in the side member of the window, such that the first flange 23 in the mounted condition is arranged to abut the side sash member 9 such that the second flange 24 extends substantially perpendicular to the first flange 23 in a direction towards an exterior side of the window 1 so as to form the ventilating passage 22 of at least a part of the side frame member 8, when mounted in the window.
- the screening element 21 is arranged to cover a portion substantially extending the length of the side member 8, 10 of the frame.
- the screening element is furthermore provided with a longitudinally extending slot 27 at a first end 25 of the screening element.
- the longitudinally extending slot 27 is as illustrated in more detail in Figs 10 and 11 provided in the surface of the second flange 24.
- the slot 27 is intended to engage with a control arrangement 30 of the window, the control arrangement having the function of provided a force for opening of the window.
- first end 25 of the screening element 21 is intended to connect with the top frame member 6 of the window so that the screening element when provided as a detachable element is attached to the side frame member 8, 10 in both ends through engagement means 40 of the bottom part of the window and abutting a top part of the frame, while being connected to a second groove 42 in the top part of the side frame member as seen in Fig. 7 .
- the L-shaped screening element 21 is provided as a thin-walled profile element of a material such as metal, plastic or composite.
- the thickness of the walls may for instance lie in the interval 0.5 to 10 mm, more preferably 1 to 8 mm, and still more preferably 2-5 mm.
- the manufacture of such an L-shaped thin-walled profile element lies well within the skills of the person skilled in the art, and will typically include technical means such as bending, moulding or extrusion in various sizes and shapes.
- the provision of ventilating passages may easily be incorporated into the manufacturing process according to the specific field of application of the window.
- the invention is not limited to a screening element having an L-shape, but that any other suitable geometrical shape could be used, such that the screening element could be in the form of a U-shape, profile having a rectangular shape or a rounded profile shape.
- the ventilation passage 22 is formed as a plurality of perforations 22a, 22b in the material of the screening element 21 opening into a cavity 28 formed in the screening element and hence in turn of the frame member in which the screening element is incorporated. This is especially shown in Fig. 10 and 11 , where the perforations in the lower end 26 of the L-shaped profile constitute the ventilating passage 22 of the screening element 21.
- the screening element is shown as a fixed element, i.e. with all portions remaining in the same position in all situations. It is conceivable, however, that the screening element may comprise a number of parts or portions which are movable relative to each other, for instance in dependence on the movement of the sash.
- the window system of the second embodiment comprises a window 101 with a dome-shaped weather shield 106. Details other than those pertaining to the present invention are apparent from the embodiment of Applicant's WO 2009/080026 A1 , to which explicit reference is hereby made and of which Figs 1 and 2 correspond to Figs 12 and 13 , respectively.
- the screening arrangement comprises a screening element generally designated 121 incorporated in one, two, three or all four members of the frame 102 and/or sash 103.
- the screening element including the ventilating passage 122 is formed in a profile element 121 having at least two adjacent sides of which the one side faces an interior or inner side of the window and constitutes said first face 123 and the other side faces an exterior or outer side of the window and constitutes said second face 124.
- the profile element 121 also constitutes the frame member 104 into which it is incorporated, that is, it forms an integral part of the frame member.
- the profile element 121 includes a cavity 28 configured to allow air flow between the first set of openings 122a and the second set of openings 122b and vice versa.
- the openings of the two sides of the screening element 121 are not contiguous, as a transition portion 129 is provided between the first face 123 and the second face 124, which separates the first set of openings 122a from the second set of openings 122b.
- An additional inner wall 128a is located slightly below the second face 124 and is provided with a set of openings 122c.

Description
- The present invention relates to a window system comprising a window including a frame and a sash, each having a plurality of members defining a frame and a sash plane, respectively, said sash (3; 103) being connected to the frame by means of at least one hinge connection, so that the sash can be moved from a closed position to an open position, and into an intermediate ventilating position, in which ventilating position the sash plane forms an angle within a limited angle range with the frame plane to provide at least one ventilating aperture in the circumferential of the frame and/or sash, and said window system further comprising a screening arrangement arranged to cover the said ventilating aperture in the ventilating position.
- It is generally known from prior art to provide window system including windows with a ventilating position, in order to provide easy ventilation of a room without the need to fully open the window. In the ventilating position the windows thus have a ventilating aperture, through which not only air can flow, but also objects, such as insects, may enter. It is in generally known from prior art to block the entry of objects through the ventilating aperture by providing the windows with a screening arrangement.
- Screening arrangements in such window systems are generally provided in the form of a screening curtain, netting or similar attached to either the frame or sash, or, in an activated screening position, to both the frame and sash, so that they can be manually activated by a user handling the screening arrangement after opening of the window or is automatically activated throughout the entire opening movement of the window, i.e. following the path of opening of the window so as to cover the full aperture provided in an open position of the window.
- A screening arrangement of this kind is known from Applicant's application no.
WO2005/005762 A1 , which discloses a pivotal roof window having a screening arrangement arranged to provide screening of the top and/or bottom part of the window exclusively. The screening arrangement is moved automatically from an inactive position corresponding to the closed position of the window to an active position corresponding to the ventilating position, and from the active position to the inactive position when the window is brought from its ventilating position to its closed position. The screening arrangement is for example formed as an element hanging freely form the top and/or bottom member or as a curtain being connected to the top and bottom member of the frame and sash. Such screening arrangements are thus useful in the sense that they block out incoming objects in the top and/or bottom of the window effectively. - However, such screening arrangements must however be formed as an element hanging freely from either the frame and/or sash or being connected to both the frame and sash in order to cover at least the bottom aperture in the ventilating position, which may create an unwanted direct visible and to some degree aesthetically unpleasing screening arrangement.
- Other solutions disclosed in the prior art are curtains or insect nets screening off the entire aperture between the sash and frame in the ventilating as well as open position of the window, as for example disclosed in
US patent no. 2311413 . This document describes a window, having a screening arrangement for screening off the aperture between the sash and frame in the open position of the window. Thus, the screening arrangement disclosed does not only cover a small aperture such as the aperture arising in the ventilating position of a window, but as the sash turns outwards when opening the window, the screening arrangement is activated so that it covers the entire opening angle between the frame and sash by a single insect net screening the entire opening angle. That is, the screening arrangement has the form of a curtain covering the aperture between the sides, top and bottom members of the window in the open position.US patent no. 1,997,206 discloses a solution where a screen is provided between the lower edge of the window sash and the forward edge portion of the sill, where the outer edge of the screen is inserted in a recess provided along the inner side of the lower portion of the sash. - Still further examples of prior art windows with screening arrangements are shown in
US patent no. 4,969,291 ,DE 42 18 088 C1 ,WO 95/34739 A1 DE 20 2008 006531 U1 . - This solution for screening off especially the sides of the window is useful in the sense that it blocks out incoming objects such as insects, while providing a ventilating passage of the window both in an open position and a ventilating position of the window. However, when provided in a roof window, generally designed especially to facilitate easy window cleaning as the sash comprising the pane can be turned essentially 180° to allow cleaning of the outside surface of the pane from inside the building, with such screening arrangements you must remember that they have to be decoupled from the frame and/or sash in order to make the 180° rotation.
- Furthermore, such arrangements limit the possibility of using the window as an exit, as in for instance fires, where the screening device has to be manually removed first, in order to create an unblocked escape opening.
- Moreover, the large screening arrangement constituted by the prior art can be aesthetically unpleasing, as the screening arrangements are blocking at least portions of the view through the window. In some examples of the prior art, the screening arrangement is clearly visible, when the window is closed, which makes these solutions less advantageous.
- Eventually, the provision of a screening arrangement in a window system will most often hamper the appearance of the window itself, just as it renders for instance cleaning and maintenance of the window more complex.
- With this background it is the object of the present invention to provide a window system with a window and a screening arrangement which meets the demands to a pleasant apperance and which is at the same time more flexible and cost-effective in manufacture, assembly and use.
- This and further objects are met by a window system according to
claim 1. By incorporating the screening arrangement as a screening element in the frame and/or sash members of the frame and/or sash itself, a simple and uncomplicated ventilating facility is achieved. Positioning the window in the ventilating position automatically provides screening of the ventilating aperture while at the same time allowing the air to pass by the first and second set of openings. - In a presently preferred embodiment, said at least one screening element including the ventilating passage is formed in a profile element having at least two adjacent sides of which the one side faces an interior or inner side of the window and constitutes said first face and the other side faces an exterior or outer side of the window and constitutes said second face. Providing the screening element as a profile element renders manufacture flexible, simple and cost-effective.
- In a further development of the preferred embodiment, the profile element includes a cavity configured to allow air flow between the first set of openings and the second set of openings and vice versa. This configuration allows optimum utilization of the space available and increases the manufacturing efficiency even further.
- The first set of openings may either be contiguous with the second set of openings, or, alternatively, a transition portion may be provided between the first face and the second face to separate the first set of openings from the second set of openings.
- In one embodiment, which is particularly advantageous in the case of retrofitting of existing window systems, the ventilating passage is formed in a separate and detachable screening element configured to be connected to said at least one frame and/or sash member in a mounted condition of the window.
- In an alternative embodiment, the ventilating passage is formed in the profile element constituting said at least one frame and/or sash member itself. This provides for a completely integrated solution of the screening arrangement in the window system and is particularly advantageous in fields of application allowing the frame and/or sash structure to be formed by profile elements.
- In a further development of the alternative embodiment, the ventilation passage is provided by openings in the first face of the profile element and openings in the second face connected via a cavity of the profile element, the cavity being separated from other parts of the frame and/or sash member. This makes it possible to achieve sufficient ventilation while at the same time retaining sufficient strength and insulation properties of the overall window.
- In a still further development, a sealing flange is provided to extend between the sash member and the frame member in the ventilating aperture of the window, such that the sealing flange abuts the transition portion in the ventilating position to allow air passage only via the ventilating passage. This provides for excellent control of the ventilating properties.
- Further details and advantages will readily appear from the following description.

Generally as shown in the Figures showing the first embodiment, thewindow 1 comprises aframe 2 and asash 3, and a hinge connection (not shown) providing a hinge axis allowing thesash 3 to rotate about the hinge axis. Theframe 2 has abottom member 4, atop member 6, and twoside members sash 3 is provided with abottom member 5, atop member 7, and twoside members - In the embodiment shown, the
window 1 is a top-hung roof window having a position of the hinge axis near thetop members 6; 7 of theframe 2 andsash 3, but the inventive concept is applicable also to centre-hung or traditional pivot windows having a hinge axis provided near a position halfway between the top and bottom members, just as a position of the hinge axis between the top and centre of the window is also possible. The hinge axis is thus substantially parallel with thetop members 6; 7 of theframe 2 andsash 3, respectively. The window is adapted to be moved between at least three positions, namely a first closed position, where the plane formed by thesash 3 is substantially parallel with the plane formed by theframe 2, a second and ventilating position, where the plane of thesash 3 forms a predetermined angle with the plane of the frame, and a third and open position, where the sash plane forms an angle, larger than the angle in the ventilating position, with the frame plane. - As illustrated in
Fig. 1 , thesash 3 of thewindow 1, when in the ventilating position, forms a pre-defined angle with the frame plane and aventilating aperture 20 is formed in the circumferential of theframe 2 andsash 3. Theventilating aperture 20 is at least partly covered by a screening arrangement, as illustrated inFig. 2 , where the screening arrangement comprises ascreening element 21 incorporated in a member of theframe 2. InFig. 2 it is only shown how the screening arrangement is incorporated in the frame structure; however it should be noticed that the screening arrangement could be arranged in the sash in a similar manner. In the first embodiment shown, a screening element is incorporated in eachside member frame 2, but configurations having a screening element in only one side are conceivable as well, just as a screening element may be incorporated in thebottom member 4 of theframe 2 as well. - The
screening element 21 is as shown inFig. 2 incorporated in the frame so as to form aventilating passage 22, and wherein thescreening element 21 automatically spans the ventilatingaperture 20 between the planes of thesash 3 andframe 2. In the first embodiment of thewindow 1, the screening arrangement is arranged in theframe 2, so that it is inconspicuous in both the open and ventilating position of thewindow 1. The term "inconspicuous" is intended to incorporate that the screening arrangement is placed in a way so it appears hidden or inconspicuous for the user's eye in both the open and ventilating position of the window. Furthermore, it is noted that the inconspicuous quality inherently excludes hindrance of the physical access through the opening. The inconspicuous characteristics of a first embodiment will be described in further detail in the following. - As illustrated in more detail in
Figs 1, 2 and3 the ventilatingaperture 20 is covered by a screening arrangement, comprising thescreening element 21, which is incorporated into theside members Fig 1 , the right side, i.e. the side of the window to the right side according to the orientation of the drawings, shows the ventilatingaperture 20 without thescreening element 21 for reasons of clarity. In the opposite, left side of the window inFig. 1 the ventilatingaperture 20 is shown covered by thescreening element 21. When thewindow 1 is moved to the position shown inFig. 1 , i.e. the ventilating position, theventilating passage 22 is formed through the thescreening element 21 incorporated in theside frame member aperture 20 ofFig. 1 is covered by thescreening element 21 as shown inFig. 2 , so that air can flow through thescreening element 21 while closing off the ventilatingaperture 20 between thesash 3 andframe 2. Insects and other objects trying to enter a room of a building from the outside are thus blocked out, since only air may flow through theventilating passage 22 of thescreening element 21. - Referring now to the closed position of the window as illustrated in
Fig. 9 , thescreening element 21 is not visible from an interior side of the window, i.e. the screening element is not visible when a person stands in a room and looks at the window, as theside members - When the window is moved to the open position, the screening element or elements are also inconspicuous, since each screening element is incorporated in the members of the frame or sash, in the embodiment shown in the
side members frame 2, thescreening elements 21 do not prevent easy opening of the window to an open position or disturb the functions of the open window, including using this as an emergency exit. The function of theventilating passage 22 created by the ventilating arrangement, comprising thescreening element 21 is especially useful, when thewindow 1 is in the predetermined ventilating position, where it covers the ventilating aperture and thus blocks the entry of objects, such as insects or similar. - Even though not illustrated in the Figures of the first embodiment, the ventilating passage could be formed by incorporating the screening element in the side members of the sash instead of the side members of the frame, possibly in combination. Furthermore, it would be possible to provide a similar solution of the previously described, wherein the
ventilating passage 22 is formed by incorporating thescreening element 21 in at least one of the bottom members of the frame and/or sash. - The
screening element 21, regardless of the member it is incorporated in, may extend the whole member it is incorporated in or a portion of the member, in order to form theventilating passage 22. In the embodiment shown inFig. 3 , theventilating passage 22 is formed to extend only a portion of theside members screening element 21 is only perforated in a portion of its length. The length of extension of theventilating passage 22 in theside members screening element 21, which in turn is dependent on the desired amount of ventilation. - In the embodiment shown in
Fig. 3 , theventilating passage 22 of thescreening element 21 is incorporated in the bottom portion of theside members ventilating passage 22 of thescreening element 21 for top-hung windows, but in other cases, such as a centre-hung window, an incorporation of thescreening element 21 in the top portion of theside members - For incorporation in other members than the side members of the frame, the bottom portions of the chosen members are desired places to incorporate the screening element for a top-hung window, and either the bottom or top portions are desired for non top-hung windows, such as pivotal or centre-hung windows. That is when using the screening element in centre-hung windows it may be desirable to block out entry in both the top and bottom apertures present in a ventilating position of the window.
- In the specific embodiment shown, the
screening element 21 is adetachable screening element 21 and the configuration of thescreening element 21 is illustrated in more detail inFig. 10 and 11 . The screening element as being detachable is configured to be connected to the at least oneframe member screening element 21 suitable for retrofitting, so that it may be produced in different sizes for fitting into different sized windows. - For attaching the
screening element 21 to the at least oneside member side member bottom member 4 or in thescreening element 21 in order to connect with thescreening element 21 in asecond end 26 of thescreening element 21. The engagement means 40 of thebottom frame member 4 is, as illustrated inFig. 9 configured as a groove in anengagement part 41 of thebottom frame member 4. - The
screening element 21 is inFigs 10 and 11 , illustrated as a screening element having the form of an L-shape, with afirst flange 23 and asecond flange 24, the second flange extending substantially perpendicular to thefirst flange 23, wherein at least one of the first and/orsecond flanges ventilating passage 22. The L-shapedscreening element 21 is as previous described arranged to be incorporated in at least one of any of the frame and/orsash members - As illustrated in
Fig. 6 , thescreening element 21 is mounted in the side member of the window, such that thefirst flange 23 in the mounted condition is arranged to abut theside sash member 9 such that thesecond flange 24 extends substantially perpendicular to thefirst flange 23 in a direction towards an exterior side of thewindow 1 so as to form theventilating passage 22 of at least a part of theside frame member 8, when mounted in the window. - Furthermore as illustrated, especially in
Fig. 7 , thescreening element 21 is arranged to cover a portion substantially extending the length of theside member longitudinally extending slot 27 at afirst end 25 of the screening element. Thelongitudinally extending slot 27 is as illustrated in more detail inFigs 10 and 11 provided in the surface of thesecond flange 24. Theslot 27 is intended to engage with acontrol arrangement 30 of the window, the control arrangement having the function of provided a force for opening of the window. Furthermore thefirst end 25 of thescreening element 21 is intended to connect with thetop frame member 6 of the window so that the screening element when provided as a detachable element is attached to theside frame member second groove 42 in the top part of the side frame member as seen inFig. 7 . - In the first embodiment described in the above, the L-shaped
screening element 21 is provided as a thin-walled profile element of a material such as metal, plastic or composite. The thickness of the walls may for instance lie in the interval 0.5 to 10 mm, more preferably 1 to 8 mm, and still more preferably 2-5 mm. The manufacture of such an L-shaped thin-walled profile element lies well within the skills of the person skilled in the art, and will typically include technical means such as bending, moulding or extrusion in various sizes and shapes. The provision of ventilating passages may easily be incorporated into the manufacturing process according to the specific field of application of the window. - It should be noted that the invention is not limited to a screening element having an L-shape, but that any other suitable geometrical shape could be used, such that the screening element could be in the form of a U-shape, profile having a rectangular shape or a rounded profile shape.
- As illustrated in the Figures in general, the
ventilation passage 22 is formed as a plurality ofperforations screening element 21 opening into acavity 28 formed in the screening element and hence in turn of the frame member in which the screening element is incorporated. This is especially shown inFig. 10 and 11 , where the perforations in thelower end 26 of the L-shaped profile constitute theventilating passage 22 of thescreening element 21. - In the first embodiment shown and described in the above, the screening element is shown as a fixed element, i.e. with all portions remaining in the same position in all situations. It is conceivable, however, that the screening element may comprise a number of parts or portions which are movable relative to each other, for instance in dependence on the movement of the sash.
- In the following, a second embodiment of the window system according to the invention will be described with particular reference to
Figs 12 to 15 . Only differences from the first embodiment will be described in detail. Elements having the same or analogous function will be denoted by the same reference numerals to which 100 has been added. - The window system of the second embodiment comprises a

Details other than those pertaining to the present invention are apparent from the embodiment of Applicant'sWO 2009/080026 A1 , to which explicit reference is hereby made and of whichFigs 1 and 2 correspond toFigs 12 and 13 , respectively. - As in the first embodiment, the screening arrangement comprises a screening element generally designated 121 incorporated in one, two, three or all four members of the
frame 102 and/orsash 103. - In the specific form of the second embodiment, the screening element including the ventilating passage 122 is formed in a profile element 121 having at least two adjacent sides of which the one side faces an interior or inner side of the window and constitutes said
first face 123 and the other side faces an exterior or outer side of the window and constitutes saidsecond face 124. In the embodiment shown, the profile element 121 also constitutes theframe member 104 into which it is incorporated, that is, it forms an integral part of the frame member. - The profile element 121 includes a
cavity 28 configured to allow air flow between the first set ofopenings 122a and the second set ofopenings 122b and vice versa. - In contrast to the first embodiment, the openings of the two sides of the screening element 121 are not contiguous, as a
transition portion 129 is provided between thefirst face 123 and thesecond face 124, which separates the first set ofopenings 122a from the second set ofopenings 122b. - An additional
