Definitions

  • the present invention relates to a roof window arrangement comprising a plurality of window units in a side-by-side configuration and a covering assembly including a set of coverings for each window unit, each window unit comprising at least one pane-carrying frame and a pane.
  • the invention furthermore relates to a method of manufacturing a roof window arrangement.
  • Roof windows to be installed in inclined roof surfaces come in a variety of types, and are either installed as stand-alone window units, in which all sides of the roof window borders on the roofing, or in configurations in which several window units are built together to combine into larger arrays providing a larger light influx into a room of a building, and in which only outer sides of the outermost window units border on the surrounding roofing.
  • Typical configurations of twin or quadruple roof window arrangements installed side-by-side and/or above each other, respectively, are shown and described in Applicant's published international application WO 2004/055291 A1 and European patent No. EP 1 581 706 B1 .
  • the window units are typically standard roof windows in which the right side frame member of the left-hand window unit is located adjacent to the left side frame member of the right-hand window unit, and/or the bottom frame member of the upper window unit is located adjacent to the top frame member of the lower window unit.
  • a roof structure comprising rafters and battens
  • at least one rafter and a number of battens will typically need to be removed to provide a sufficiently large aperture in the roof surface and roof structure
  • specially designed gap trimmers are normally mounted between the window units and fastened to the roof structure in order to ensure sufficient strength and support for the roof window arrangement.
  • CZ 280 295 B6 shows another example of a roof window arrangement.
  • the standard roof windows constituting the window units of the prior art roof window arrangements are installed with a relatively small distance between adjacent side frame members, typically about 18 mm, which leaves sufficient space for trimmers etc.
  • a covering assembly comprising a combination of flashing, cover and cladding elements which provide a weather-tight transition to the surrounding roofing and ensure tightness around each window unit and between adjacent window units.
  • the prior art covering assemblies function well, they are dependent on a relatively large number of tailor-made components that must be manufactured, stored, transported, and assembled at the building site.
  • the configuration may lead to a flexible roof window arrangement, where the roof windows can open independently from each other. Furthermore, this solution may enable thinner frames which improve the aesthetic appearance of the window and do not obstruct the outdoor view. It may also improve the daylighting conditions inside the room as the net glazing area may be increased.
  • At least one window unit may comprise at least one side frame covering configured to function as a covering of a neighbouring window unit. This facilitates the easier assembly of the roof window arrangement.
  • the side frame covering may comprise a snap lock part, which may allow for an easy mounting providing a snap effect.

  • the cap member 56 comprises one flange 564 to form a transition between the second window unit 22 and the neighbouring first window unit 21 and engagement means to engage with the second window unit 22. Similar means may be provided at the other side.
  • the position of the cap member 56 and flange 564 are also shown in Fig. 7 .
  • the bottom covering 5223 of the pane-carrying frame of the second window unit 22 could from the outset be produced with side flanges, which are removed and replaced by the flange 564 of the cap member 56 at the respective end.
  • the cap member 56 comprises a base 561 from which the flange 564 protrudes, an end portion 563 depending from the base 561, a first leg 562 and a second leg 574.
  • the engagement means comprise the base 561, the first leg 562 and the second leg 574 are configured to abut the frame member 225.
  • the cap member 56 is in the embodiment shown slid on the frame member 225 such that an entire end portion of the end member 225 is surrounded by the engagement means 561, 562, 563, 574.
  • the frame member 225 is provided with an end portion (not shown in detail) with a lower height relative to the remaining portion of the frame member 225.
  • a shoulder portion 565 is provided such that the shoulder portion 565 is located at a higher level than the base 561 and is connected to the base 561 via a step portion 5651.
  • the cap member 56 also comprises a first bottom sealing flap 568 and a second bottom sealing flap 569 configured to abut the secondary bottom frame covering 533 of the covering assembly 5. Since the secondary bottom frame covering 533 in the embodiments shown is through-going, i.e. extends the full width of the three window units, the first and second bottom sealing flaps 568 and 569 abut the same element, thus providing a particularly tight connection.
  • a trough 567 is formed between an upstanding portion 566 and the flange 564 to interact with components of the second window unit 22, including a part 5223a of the bottom pane-carrying frame covering 5223 and a glazing bead 5224, as shown in Fig. 18 .
  • a sealing rib 570 is comprised in the trough 567 to enable a water tight connection.
  • a top sealing flap 572 is also comprised in the cap member 56, which is adjacent to the upstanding portion 566. As shown in Fig. 21 , the top sealing flap 572 abuts the bottom pane-carrying frame covering 5223 in the mounted condition.
  • the upstanding portion 566 of the trough 567 also comprises a guide tower 571 which provides stiffness to the top sealing flap 572.
  • the flange 564 further comprises a front tower 573 at one end of it, which acts as blocking water and/or wind from blowing into the construction.
  • the front tower 573 thus substantially blocks the slit formed between the bottom pane-carrying frame covering 5223 and the adjacent bottom sash covering 5213, when the first window unit 21 is in the closed position. Also visible in Fig. 21 are a gasket 2215 of the bottom member 2214 of the pane-carrying frame 221 of the second window unit 22 and an insulating element 2216.
  • the gasket 2215 and the insulating element 2216 are known per se and are described in more detail in Applicant's German utility model DE 20 2012 009 491 U1 .
  • the top sealing flap 572 provides a seal between the cap member 56 and the bottom pane-carrying frame covering 5223, and the guide tower 571 ensures correct mounting of the gasket 2215 relative to the cap member 56.
  • a side tower 5741 is provided on the second leg 74.
  • a first and a second side wing 5641 and 5642 are provided on the flange 564.
  • a front wing 5631 is provided on the end portion 563 of the cap member 56.
  • a fixation tower 5611 is present as shown in Fig. 24 .
  • the second leg 574 has an extension portion 5742 and a rear rib 5743, both of which contributing to improving the sealing properties of the cap member 56.
  • Figs. 26 and 27 show an alternative embodiment of the roof window arrangement, making use of a particular configuration of the gasket 2252 indicated schematically in Fig. 7 .
  • the gasket 2252 extends between the lower end of the glazing bead 5224 of the second window unit 22 and up to a position at or near the frame hinge part 222 and provides a main sealing surface 2252a towards the side sash covering 5212 to block water entering into the window construction.
  • the gasket 2252 is furthermore formed with a depending leg 2252b extending inwards from the main sealing surface 2252a and provided with an internal sealing profiling 2252c.
  • an engagement flange 2252 is provided for engagement with the glazing bead 5224 and the right-hand side of which interacts with the cap member 56.
  • a glazing bead 5214 of the first window unit 21 is also visible in Fig. 26.
