Definitions

  • the present invention relates to a roof window set according to the preamble of claim 1.
  • DE 10 2004 052936 discloses such a roof window set.
  • the air outlet functions as a duct providing fresh air to rooms independently from other ventilation systems used in buildings.
  • the necessity to use air outlets occurred as a result of the trend towards a reduction of heat losses in buildings by excessive sealing and blocking of natural air exchange in rooms.
  • air outlets are used in exterior wall windows, however in case of attics, where most often roof windows are the only windows, a need for air outlets built-in into the structure of the roof window has arisen.
  • Air outlets installed in the window structure are a natural solution, because of relative ease of their manufacturing and installation. In this case, making additional air outlet openings in the exterior wall or in the roof is not necessary.
  • Patent Application No. WO 2008/133539 A2 presents a window frame with a built-in air outlet.
  • a solution for an automatic pressure-controlled opening or closing method of the air supply duct is disclosed in this application.
  • solutions of such a type force significant enlargement of the window frame dimensions in order to integrate the air supply duct.
  • the window frame width had to be significantly enlarged.
  • Patent Application No. WO 03/001017 A1 shows a casement frame with a built-in air outlet.
  • the main element of this solution is a circular rotary ventilation valve installed in an opening made in the installation strip being a part of the top casement frame.
  • the air duct is formed by the said ventilation valve and the space defined by the walls of the casement frame from one side and by the window frame walls from the other side.
  • a disadvantage of this solution consists in a significant reduction of the window clearance accompanied by a small size of the ventilation duct.
  • the rest of the installation strip is not used.
  • this solution is hard to use in roof windows because of a lack of protection from weather conditions.
  • a similar idea is constituted by an air outlet proposed in Patent Application No.
  • WO 2005038165 A1 A ventilation opening in the installation strip being a part of the window casement is closed by a flap valve, and the air supply duct is profiled in a way preventing penetration of water from the typical direction of precipitation.
  • This solution is suitable both for exterior wall windows and roof windows.
  • the proposed solution according to claim 1 introduces a possibility to install the air outlet in the set, along with a possibility of free and unrestricted forming of the window frame profile.
  • the distinguishing feature of the invention consists in the features of the characterising portion of claim 1.
  • the advantage of the solution is a possibility to shape the elements of the roof window and those of the air outlet independently. It is of a particular importance for the possibility of heat-insulation and aesthetic forming of profiles of the frame and the window frame.
  • An important advantage of the solution is a possibility of installation of the air outlet in an existing window within the framework of a retrofit. In this case, it is necessary to enlarge the window opening in the roof by the dimension of the air outlet. In case of a full retrofit within the framework of the existing window opening, a replacement of the window with a window of smaller dimensions is possible, preferably within the framework of a standard dimensional series of windows, and installation of the air outlet in the cleared space.
  • An important feature of the invention consists in the fact that the shape and dimensions of the external surface of the air outlet, mounted on the reveal of the window opening during installation, are preferably the same as the shape and dimensions of the external surface of the window frame, on which the air outlet is mounted.
  • the external surface of both the window frame and the air outlet should be understood as a surface serving the purpose of mounting on the reveal of the window opening and preferably parallel to the reveal surface.
  • the proposed solution offers a possibility to retrofit the window set and to adjust the flow of fresh air in the rooms cheaply and easily, particularly in case of attics, where the roof windows are being installed. Also in case of new installations, the proposed solution provides a high flexibility in installation of windows with and without an air outlet, because a window from the set may be installed independently, as well as an air outlet may be installed in any other window, while the condition of similar dimension of the element of the window frame, on which the outlet is to be installed, is met.
  • the external outline of the air outlet is basically the shape of a rectangular prism with protective and installation elements formed.
  • the interior of the air outlet is built of air supply ducts.
  • Dimensions of the outline are defined by its length, width and height.
  • the length is basically the longest dimension of the air outlet, while assembled with the window, preferably parallel to the longitudinal edge of a selected frame member of the window frame, on which the air outlet is mounted.
  • the width and height are lateral dimensions of the outline, with the width defining the dimension in a direction basically perpendicular to the window surface.
  • the height defines a dimension perpendicular to length and width, which while assembled with the window is basically perpendicular to the plane of the external surface of the window frame, the height corresponding to the short size in the plane of the window in the case that the air outlet is in the form of a rectangular prism.
  • an air outlet mounted on the external surface of the frame top member or the frame bottom member of the window frame its length is preferably equal to the length of these elements, while its height may have any value in the range of dimensions of the window opening.
  • its length is preferably equal to the length of the frame side member of the window frame, and its height may have any value in the range of dimensions of the window opening.
  • the length of the frame bottom member and the frame top member correspond to the width of the outline of the window frame
  • the length of the frame side members corresponds to the height of the window frame.
  • the length of the air outlet as a rule corresponds to the length of the element on which the outlet is mounted.
  • a window set with an air outlet preferably has an external shape that allows installing external additions, e.g. roller blinds, used in a window from the set but without an air outlet. Therefore, usage of the air outlet is neutral for the possibility to utilise additions used in standard windows.
  • the air outlet is equipped with a longitudinal channel with a shape close to letter U, draining off water, fixed to the frame by one side, in parallel to the edge of the frame top member.
  • the second edge of the longitudinal channel is used for connection with the sheet metal flashing of the window frame.
  • the connection of the longitudinal channel with the sheet metal flashing of the window frame is realised, preferably and sufficiently, by a single standing seam. Such a connection has two important features: ease of assembly and disassembly, and adequate resistance to weather conditions.
  • the air outlet has an eave, terminated over the longitudinal channel and formed preferably in parallel to it.
  • the external surface of the eave is preferably located in the plane of the external surface of the sheet metal flashing of the window frame.
  • the distance between the internal surface of the eave and the edge of the longitudinal channel determines the size of the clearance of the air supply duct and it should be adjusted to the designed size of the air supply duct. A too long distance increases the possibility for water to penetrate the interior in case of heavy rainfall, while too short distance increases flow resistance of the air stream.
  • a single or multiple pass-through air supply duct is made, connecting the niche defined by the eave and the longitudinal channel, with the space at the internal side of the window.
  • Number and size of the air supply duct openings should be adjusted to the designed volume of the air stream flowing through the air outlet. Considering the mechanical strength, particularly with long frames of the air outlet, it is more preferable to use a duct with a higher number of smaller openings than with one wide opening along the frame of the air outlet.
  • known solutions applied in windows may be used, e.g. automatic: pressure-controlled, humidity-controlled or other systems. The simplest and cheapest solution is to use a manually-removable blanking plug, covering the air supply duct from the side of the space at the internal side of the window.
  • FIG. 1 A complete set of a roof window with an air outlet in the proposed embodiment is shown while assembled as an isometric drawing in Fig. 1 .
  • the set without selected elements of the sheet metal flashing is shown in Fig. 2 .
  • the set is basically composed of a window frame 1, with a casement 2 mounted in it in any way, and of the air outlet 3, being a separate module.
  • Fig. 3 the top fragment of the roof window comprising the frame top member 11 of the window frame 1 and the air outlet 3 installed on it, is shown in isometric view.
  • Fig. 4 a cross-sectional view without background through the casement 2, the frame top member 11 and the air outlet 3 while assembled, is shown.
  • the air outlet 3 is mounted on the external surface 14 of the selected element of the window frame 1.
  • the element having the air outlet 3 mounted is the frame top member 11, however the proposed solution may be also realised in other configurations, not shown in the figures, with the air outlet 3 installed on the external surface 14 of the frame bottom member 12 or the frame side members 13.
  • the air outlet 3, mounted on the frame top member 11, has its external outline basically in the form of a rectangular prism with formed sheet metal protective elements.
  • the protective elements are basically a longitudinal channel 31 and an eave 32, protecting the inlet of the air supply duct 33.
  • the longitudinal channel 31, laid preferably in parallel to the longitudinal edge of the frame top member 11, has a cross-section in the shape of letter U.
  • One arm of the longitudinal channel 31 is fixed permanently to the frame 34 of the air outlet 3, in parallel to the edge of the frame top member 11.
  • the other arm of the longitudinal channel 31 is being connected during assembly, preferably by a single standing seam, with the sheet metal flashing 15 of the window frame 1.
  • the air outlet 3 when the air outlet 3 is mounted on the external surface 14 of the frame bottom member 12 of the window frame 1, its length is equal to the width of the window frame, equal to the length of the frame bottom member, and its height may have any value in the range of dimensions of the window opening.
  • its length when the air outlet 3 is mounted on the external surface 14 of the frame side member 13, its length is equal to height of the window frame 1, equal to the length of the frame side member 13, and its height may have any value in the range of dimensions of the window opening.
  • the external surface 35 of the air outlet 3 is preferably a functional copy of the external surface 14 of the window frame 1 and it allows using standard flashings 4, sealing the connection of the air outlet 3 with the roof decking, similarly as in case of a window without an air outlet.
  • the term "functional copy" means that the external surface 35 of the air outlet 3 has a shape and dimensions enabling serving the same purpose as the external surface 14 of the window frame 1, i.e. it allows installing the window and the air outlet 3 in a window opening, as well as installing the flashing 4 and other dedicated elements of the window.
  • an air supply duct 55 is made, basically perpendicular to the surface of the window.
  • the air supply duct 33 connects the external space, defined by an eave 32 and a longitudinal channel 31, with the internal space, basically at the internal side of the window.
  • the length of the eave 32 and its distance from the longitudinal channel 31 is chosen so that the system protects the inlet of the air supply duct 33 from external weather conditions.
  • the air supply duct 33 may be made as a single-opening or multi-opening version.
  • the air supply duct preferably has an element or a device serving the purpose of closing or adjustment of the air flow.
  • the air outlet 3 is equipped with a blanking plug 5, covering the air supply duct 33, installed as push-in in the inlet opening of the air supply duct 33, at the internal side of the window.
  • the blanking plug 5 may be replaced with known devices controlling the air flow.
  • An internal strip 6 constitutes an additional element for fixing the air outlet to the window frame and at the same time playing a decorative role.
  • the internal strip 6 is fixed to the window frame 1 and to the frame 34 of the air outlet 3, stiffening the whole set. Empty space between the longitudinal channel 31 and the internal strip 6 is preferably filled with heat insulating material 7.
