Definitions

  • the present invention relates to a roof window, particularly for installation in an inclined roof surface, comprising a frame, a sash configured to be moved between a closed position and an open position, in which the sash assumes an angle relative to the frame, a set of hinges, and a covering arrangement including a frame side covering element having a top portion and an end edge, and a sash side covering element having a top portion and an end edge facing the end edge of the frame side covering element to form a gap, said covering arrangement being configured to cover at least said hinge in the closed position of the sash.
  • the invention furthermore relates to a method of providing a roof window with improved covering arrangement.
  • roof windows may be provided in a number of varieties and include more or less complicated structures in order to allow opening of the sash and to fulfil other functions, such as ventilation, while permitting cleaning of the outside of the pane from inside the building.
  • the varieties include roof windows of the pivoting type, the hinge axis being either located at the centre or displaced from the centre of the window, and top-hung roof windows that pivot for cleaning by means of an intermediate frame.
  • Such hinged roof windows are known for instance from GB1473570 A , DE2628691 A1 and EP0352206 A1 .
  • the covering elements thus generally comprise at least two parts, one for covering the sash hinge part and one covering the frame hinge part.
  • the covering elements are designed to protect the hinge and interior parts of the window from amongst other things weather, dirt and grime, since this may cause the hinge to rust and in worst case cause the window to leak rain water and thereby possibly cause damage.
  • the two covering elements are designed to allow an angular motion relative to each other, while opening and closing the window.
  • the covering elements are typically made of metal which is well-known to possess excellent strength and wearability properties.
  • Applicant's European patent No. EP 1 070 179 B1 describes how a joggled connection member on the sash cover element is inserted under the end of the frame cover element to provide a pressure relief chamber to prevent water penetration. While this solution has proven to function well, it can be difficult to control the exact configuration of the elements of the covering assembly in the mounted condition on the roof window, due to the unavoidable manufacturing tolerances.
  • this is achieved with a roof window according to claim 1.
  • the invention is based on the recognition that it will be more or less impossible to eliminate the gap between the respective end edges of the frame and sash side covering elements in the closed position of the sash, due to the presence of manufacturing tolerances and provides an alternative means of preventing water and other precipitation from entering below the frame and sash side covering elements.
  • influencing the flow conditions at or near the gap, in the closed position of the sash provides for sufficient influence on the flow of wind-impacted precipitation to form an outgoing stream of air to counteract penetration of water through the gap.
  • the at least one transition element includes a first transition element connected to the sash side covering element and having a first venturi portion configured to face an interior side of the top portion of the frame side covering element in the closed position of the sash to provide a constricted section between an inner channel section and an outer channel section, nearest said cap.
  • the venturi effect will occasion a reduction in the pressure and an ensuing increase of the velocity of the air stream. Expressed in another way, this will have the effect of drawing any precipitation in the form of rain, snow etc. in the direction towards the outdoor, i.e. the external side of the side covering elements.
  • a second transition element is connected to the frame side covering element and comprising a flat portion and a second venturi portion to be located opposite the first venturi portion in the constricted section between the inner channel section and the outer channel section in the closed position of the sash. This will enhance the venturi effect even further.
  • the first transition element comprises a breaker portion configured to be located in the gap between the respective end edges of the frame side covering element and the sash side covering element in the closed position of the sash.
  • the upstanding breaker portion will enhance the flow conditions even further to prevent in-flow of water under the covering arrangement.
  • a method of providing a roof window with improved covering arrangement according to claim 3 is devised.
  • the window comprises a sash 2 carrying a glazing in the form of a pane 3 and a frame 1.
  • the window is intended to be built into a surface, which is inclined with respect to the horizontal, typically a roof, and the window will in the following be referred to as roof window.
  • a hinge connection between the frame 1 and the sash 2.
  • the hinge connection in Fig. 1 comprises a set of hinges, of which one hinge 10' is visible. The same operation as described above and from here on is also true for the type of hinge described in the Applicant's pending Danish patent application No. PA 2015 70717 filed on 06 November 2015 .
  • hinges that include pivot hinges are for instance disclosed in Applicant's EP 1 038 083 B1 and EP 1 781 883 B1 , which are very versatile as regards operational areas and adaptation of components. Examples of roof windows incorporating such adapted hinges are shown in Applicant's published European patent applications EP 2 770 146 A1 and EP 2 770 149 A1 . From a closed position, the user operates the operating device of the window.
  • the operating device typically comprises a handle (not shown) connected with the sash bottom member and/or an operating and locking assembly including a ventilation flap at the sash top member with a lock mechanism to interact with a striking plate on the frame top member.
  • the hinge 10 exerts a moment on the sash 2, and in combination with the force, and hence moment, exerted by the user operating the operating device, the moment resulting from the weight of the sash 2 and pane 3 is overcome, along with any frictional forces present.
  • the opening operation entails that the sash 2 is moved from a closed position to an open position as represented by Fig. 1 , in which the sash plane forms an opening angle with the frame plane.
  • Closing the window from the open position entails the opposite movement of the sash 2. It is possible to position the sash 2 in a number of arbitrary opening positions, in which the sash 2 is held stable relative to the frame 1.
  • the sash 2 is also able to be rotated substantially through 180° to allow cleaning of the outside of the pane 3 from the inside of the building in which the roof window is installed.
  • the frame 1 and sash 2 is each formed by four members of which one frame side member 1a and one sash side member 2a are indicated.
  • the sash 2 is openable with respect to the frame 1, as the sash 2 may be moved from a closed position, in which e.g. the sash side member 2a is substantially parallel with the frame side member 1a, to an open position, in which the sash side member 2a forms an angle with the frame side member 1a.
  • the sash 2 rotates about a hinge axis ⁇ situated at the hinge connection. As indicated in Fig.
  • the hinge axis ⁇ is located between a centre axis and the top of the roof window, preferably in the interval 1/3 to 2/3 of the distance between the centre axis and the top, most preferred substantially at 1/2 of the distance between the centre axis and the top.
  • Other positions of the hinge axis are of course conceivable, for instance at the centre of the roof window.
  • the roof window comprises a covering, including flashing members (not shown), cladding and covering elements of which a frame side covering element 1b' and sash side covering element 2b' are shown.
  • the parts of the covering of the prior art roof window are connected to the frame and the sash, and to the hinge in a hinge and covering assembly as described in detail in the above-mentioned embodiment of EP 2 751 354 B1 .
  • the prior art depictions of Figs 1 and 2 correspond to Applicant's published European patent application EP 3 252 250 A1 .
  • connection of the frame side covering element 1b' and sash side covering element 2b' to the respective hinge part of the hinge 10' is carried out by a snap anchor 60', 70'.
  • a cranked portion 2c' of the sash side covering element 2b' ensures a tight and flush transition between the sash side covering element 2b' and the frame side covering element 1b' in the closed position of the roof window.
  • the movement pattern of the hinge allows that the sash side covering element 2b' is able to be retracted from its position under the frame side covering element 1b' during the opening movement of the sash 2 relative to the frame 1, and conversely, be inserted under the frame side covering element 1b' at the final stage of the closing movement.
  • the roof window as comprising the frame 1, the sash 2 configured to be moved between a closed position and an open position, in which the sash 2 assumes an angle relative to the frame 1, and a set of hinges 10 corresponding to the components described in the above.
  • the covering arrangement includes a frame side covering element generally designated 11 having a top portion 111 and an end edge 115.
  • a sash side covering element generally designated 12 has a top portion 121 and an end edge 125 facing the end edge 115 of the frame side covering element 11 to form a gap 15. It is understood that the dimensions of the gap 15 will vary according to manufacturing tolerances, not only due to the covering arrangement itself but also of other components of the roof window. Furthermore, a gap is present between the two side covering elements 11, 12 both when the sash is open and closed, but in the following, the gap 15 will referred to as the space between the end edges 115, 125 of the respective frame and sash side covering elements.
  • the covering arrangement is configured to cover at least the hinge (not shown) in the closed position of the sash 2, but also other components of the roof window such as the frame and sash side members.
  • Each of the frame and sash side covering elements 11 and 12 has an external side facing the outdoor and an internal side facing the indoor.
  • a central feature is that the covering arrangement includes at least one transition element 13, 14 connected to one of the frame side covering element 11 and the sash side covering element 12, near or at the respective end edge 115, 125 of the frame side covering element 11 or the sash side covering element 12.
  • the at least one transition element includes a first transition element 13 connected to the sash side covering element 12 and having a first venturi portion 138 configured to face an interior side of the top portion 112 of the frame side covering element 11 in the closed position of the sash 2 to provide a constricted section between an inner channel section 17 and an outer channel section 16, nearest said cap 15.
  • first venturi portion 138 is formed on a flange portion 137 of the first transition element 13, said flange portion 137 being formed in conjunction with an offsetting portion 136 adjacent a top portion 131 configured to abut an interior side of a top portion 121 of the sash side covering element 12 near the end edge 125 thereof.
  • the first transition element may be formed in any suitable manner; however, it is preferred that the first transition element 13 as shown has an inner side portion 133 to match a corresponding inner side portion 123 of the sash side covering element 12. Furthermore, the first transition element 13 here has a drain portion 134 to match a corresponding drain portion 124 of the sash side covering element 12 and to be positioned in extension of a corresponding drain portion 114 of the frame side covering element 11. Finally, the first transition element 13 comprises an extended portion 139. The extended portion 139 ensures safe retention and guidance of the first transition element 13 in the cooperation with the sash and frame side covering elements 12, 11.
  • the first transition element 13 comprises a breaker portion 135 configured to be located in the gap 15 between the respective end edges 115, 125 of the frame side covering element 11 and the sash side covering element 12 in the closed position of the sash 2.
  • the breaker portion 135 here comprises a breaker back plate 135a extending at the end edge 125 of the sash side covering element 11 and protruding above the external side of the top portion 121 thereof.
  • the breaker portion 135 comprises a plurality of breaker vanes 135b, preferably located at an angle to said breaker plate 135a, forming a corresponding plurality of breaker vane interstices 135c.
  • a second transition element 14 is connected to the frame side covering element 11 and comprising a flat portion 141 and a second venturi portion 142 to be located opposite the first venturi portion 138 in the constricted section between the inner channel section 17 and the outer channel section 16 in the closed position of the sash 2.
  • transition element or elements 13, 14 are provided separately from the sash and frame side covering elements 12, 11, a connection must be carried out in order to retain the components to each other. In principle, this could be performed by traditional mechanical techniques such as snap locking or friction engagement, possibly in support of adhesive connections, but these techniques do not create a roof window as claimed.
  • each transition element 13, 14 is connected to the respective sash or frame side covering element 12, 11 by the use of a) engraving an interior surface of the covering element to provide an engraved surface with at least one cavity by subjecting the covering element to a laser beam at a polar angle; and b) attaching the at least one transition element 13, 14 to the covering element 12, 11 by introducing a portion of the transition element into the least one cavity. Details of such joining techniques are found in Applicant's co-pending international application No. PCT/DK2017/050356 .
  • transition element or elements 13, 14 integrally with a snap anchor (corresponding to above prior art elements 60' and 70') configured to connect with a corresponding receiving section of a respective hinge part of the set of hinges.
  • sealings may for instance include flaps forming one-way valves, allowing water present under the covering elements to exit but blocking the passage of water and other precipitation from entering.
  • the invention further provides a method of providing a roof window with improved covering arrangement, comprising the steps of: providing a frame (1) and a sash (2), providing a covering arrangement including a frame side covering element (11) having a top portion (111) and an end edge (115), and a sash side covering element (12) having a top portion (121) and an end edge (125), providing at least one transition element (13, 14),
