Definitions

  • the present invention relates to a roof window comprising a frame, a sash, and a pane, in which the frame comprises a set of frame members including a top frame member, two side frame members and a bottom frame member and the sash a set of sash members including a top sash member, two side sash members and a bottom sash member, each frame and sash member defining a longitudinal direction, and in which the roof window (1) furthermore comprises a hinge assembly configured to allow the sash to be tophung about a substantially horizontal first hinge axis in a first operational condition in a mounted condition of the roof window and comprising a hinge unit with a frame hinge part connected to or connectable to at least the top frame member and a sash hinge part connected to at least the top sash member.
  • Roof windows to be installed in inclined roof surfaces come in a variety of types.
  • parameters such as operability, thermal properties, weather-tightness, and suitable finishing to the interior of the building are typically given substantial weight; however, it is also often desired and in some areas in fact necessary to factor in the external appearance as well.
  • certain requirements apply whether the installation concerns a newly fitted roof window, or to replace an existing window or rooflight as part of a renovation or refurbishment project.
  • the conservation roof window is able to be installed with a "low profile", i.e. that the height of the parts of the roof window protruding above the surrounding roofing is as small as possible. This is particularly pronounced in buildings with substantially flat roofing materials, such as slate or shingle. To meet this requirement, most major roof window manufacturers allow installation in at least two levels, thus accommodating the height of various roofing profiles and installation conditions.
  • this and further objects are achieved with a roof window of the kind mentioned in the introduction, which is furthermore characterised in that a sash installation component is provided to support the sash in a second operational condition of the roof window.
  • Providing a sash installation component facilitates the installation process, since it is able to free manual support.
  • the sash installation component may be re-used when installing another roof window.
  • Suitable materials include polymeric foam, moulded cardboard, and organic materials.
  • the sash installation component makes it possible to perform a stepwise installation of the sash.
  • the installation is facilitated since the sash installation component supports the sash while in the second operational condition, thus freeing the installer to attend to other tasks etc.
  • the hinge assembly comprises a coupling unit connected to or connectable to the frame and configured to be connected to the hinge unit in the mounted condition of the roof window, and wherein, in an installation condition of the roof window, the hinge unit is connected to the sash and the coupling unit is connected to the frame.
  • each coupling unit comprises one top frame coupling plate and one side frame coupling plate, and wherein the coupling unit is configured to allow selective coupling of the frame hinge part of the associated hinge unit to the top frame coupling plate and the side frame coupling plate in the first operational condition, and to only the side frame coupling plate in a second operational condition. This improves the installation conditions even further.
  • the side frame coupling plate comprises a base section connected to an inner side of the side frame member, and wherein the engagement means of the top frame coupling plate comprise a key-hole shaped recess in the base section of the side frame coupling plate configured to cooperate with a secondary hinge pin to engage and lock the hinge unit to the side frame member in the first operational condition and to allow rotation of the sash about a substantially horizontal second hinge axis in the second operational condition, said secondary hinge pin constituting engagement means of the frame hinge part.
  • the engagement with the side frame coupling plate is made particularly simple and easily attained, and at the same time, unintentional release of the engagement is prevented.
  • said means are configured to allow decoupling of the hinge unit from the top frame member so as to allow the sash to rotate about the second hinge axis.
  • the hinge unit is preferably connected to the sash and the coupling unit is connected to the frame.
  • the sash is configured to assume a side coupling position, a top coupling position, and a service position in the second operational condition.
  • the sash installation component comprises a body portion, a frame engagement portion and a plurality of support surfaces for the sash.
  • the configuration of the sash installation component is optimised, since the respective portions may be formed substantially independently of other portions.
  • the sash installation component comprises three distinct support surfaces, namely a first support surface to support the bottom sash member in the side coupling position, a second support surface to support the bottom sash member in the top coupling position, and a third support surface to support at least one side sash member in the service position.
  • the frame engagement portion is shaped in accordance with a profile of the bottom frame member, preferably including an interior contact section, a first inner contact section, a first exterior contact section, a second inner contact section, and a second exterior contact section, more preferably also an interior end section and an outer end section.
  • the first support surface may be separated from the second support surface by a dividing rib. In this way it is ensured that the sash is positioned correctly in view of the process step to be carried out, that is, side coupling, top coupling, or servicing.
  • Appropriate support is achieved in an embodiment in which the portion of the sash installation component, in which the third support surface is formed, is wider than the body portion.
  • the sash installation component is made from a material selected from the group comprising: polymeric foam, moulded cardboard, organic materials.
  • the sash installation component may be reused, recycled by appropriate environmentally responsible disposal means, recovered for other uses, or even composted.
  • a feature described in relation to one of the aspects may also be incorporated in the other aspect, and the advantage of the feature is applicable to all aspects in which it is incorporated.

  • the pane 4 comprises a number of edge portions generally associated to members of the sash 3 as will be described in further detail below.
  • An exterior pane surface 4e defines a plane of the roof window 1 in an assembled condition of the roof window 1.
  • the assembled condition of the roof window 1 is achieved when main components of the frame 2 and sash 3 have been assembled and the frame 2 and sash 3 are connected to each other, for instance in an installed position when the roof window 1 is ready for use.
  • an assembled condition of the sash 3 is achieved once main components of the sash 3 have been assembled, and an assembled condition of the frame 2 when main components of the frame 2 are assembled.
  • main components is to be understood as encompassing primary parts of the roof window necessary to perform all operational functions, and not including accessories or auxiliary equipment.
  • An interior pane surface 4i faces the interior, typically a room of a building subjacent the roof surface in which the roof window 1 is installed.
  • a glazing bar 45 is fitted to the exterior pane surface 4e, and a glazing bar cover 46 is fitted on the interior pane surface 4i.
  • the sash 3 is openable relative to the frame 2, to obtain one or more open positions. In such open positions, the sash 3 and pane 4 are moved out of the plane of the roof window 1.
  • the sash 3 is shown as being tophung, i.e. during normal use, the sash 3 is rotated about a substantially horizontal hinge axis at or near the top frame member 21 and top sash member 31. It is however conceivable to apply some principles of the presented concepts for roof windows on different types of windows having other opening patterns, or being provided as fixed skylights.
