Definitions

  • the present invention relates to a roof window with a stationary primary frame, at least one secondary frame such as a sash and/or intermediate frame, and a lifting device comprising a lifting arm inserted between the primary frame and the at least one secondary frame.
  • the invention furthermore relates to a method of assembling a lifting device.
  • Windows for installation in an inclined roof surface may be provided in a number of varieties and include more or less complicated operational structures to allow opening of the sash and to fulfil other functions, such as ventilation.
  • Such roof windows include the type hinged at or near the centre, the top-hinged type, and finally the roof windows that are top-hinged during normal operation but in which the sash is able to perform a rotating movement substantially at a centre axis, either for cleaning or for providing an alternative manner of operation.
  • Roof windows of the top-hinged type have a first hinge axis provided by a top hinge arrangement to provide a first operational condition, whereas rotation of the sash in a second operational condition is performed by means of an intermediate frame in which the sash is hinged to provide a secondary hinge axis.
  • one hinge of the hinge arrangement will be located at either side of the roof window to define a substantially horizontal hinge axis.
  • top-hinged windows with a second operational condition are for instance disclosed in Applicant's WO-A-89/10460 , EP 0 733 146 B1 , EP 1 873 323 B1 , EP 2 762 665 A2 , and WO 2019101281 A1 .
  • the sash structure is connected with an intermediate frame with frame arms, which in the closed position of the window are positioned between the upper parts of the frame and sash side members, and which during normal use of the window as a top-hung window follow the sash side members.
  • Such a lifting device is for instance disclosed in the Applicant's WO2019/101281 A1 where a spring assembly acts as a force balancing element to the pane-carrying frame by operating on a lifting arm attached to the frame.
  • a roof window of the kind mentioned in the introduction which is further characterised in that the lifting arm has a first end rotatably connected with a sledge slidably connected with the primary frame in a sledge guide and a second end rotatably connected with the at least one secondary frame.
  • the lifting device further comprises a spring assembly configured to be coupled to the sledge.
  • the lifting device further comprises an adjustment system and an adjustment arm, wherein the adjustment system is mounted to the sledge guide and the adjustment arm has a first end rotatably connected to the lifting arm and a second end connected to the adjustment system, such that the adjustment arm and the lifting arm are connected at an angle with a value ( ⁇ 1 ).
  • the angle value ( ⁇ 1 ) assumes a second angle value ( ⁇ 2 ) by adjusting the position of the second end of the adjustment arm by means of the adjustment system.
  • the adjustment system provides a system for adjusting the roof window for different roof inclinations.
  • the spring assembly When the spring assembly is coupled to the sledge one or more springs in the spring assembly exerts a pulling force on the sledge. This results in the first end of the lifting arm experiencing a pull and a rotation around the connection point with the adjustment arm. As a result, the lifting arm is forced into a position with its longitudinal end substantially perpendicular to the sliding direction of the sledge in the sledge guide resulting in an opening of the roof window.
  • the force exerted by the lifting arm on the secondary frame is related to the positioning of the secondary lifting arm relative to the lifting arm and spring.
  • the roof window can be balanced to a roof inclination in the range of 15° - 65°.
  • the adjustment system may comprise an adjustment screw.

  • the cogwheel may be adapted to cooperate with the outer geometry of a mechanical tool.
  • the adjustment system may further comprise an adjustment bushing wherein the second end of the adjustment arm is connected to the adjustment screw through the adjustment bushing, such that the adjustment bushing is configured to move axially on the adjustment screw.
  • the adjustment bushing allows for minimum friction connected between the adjustment screw and the adjustment arm. As the adjustment arm is adjusted on the adjustment screw, the angle between the adjustment arm and the lifting arm changes. Simultaneously, the angle between the adjustment arm and the adjustment screw may change.
  • the bushing provides a suitable mechanism that allows such a rotation.
  • the bushing may comprise a cylindrical or cyclical body engaging with the adjustment screw via a through hole.
  • the through hole of the adjustment bushing may have an inner geometry to engage with an outer bushing of the adjustment screw.
  • the adjustment bushing may further have at least one end part projecting from the body and configured to engage with a track or a slot on the sledge guide. This track or slot may be called engagement slot.
  • the adjustment system may further comprise a disc configured to be in connection with and/or adjacent to the second end of the adjustment arm.

  • Fig. 9 shows a perspective view of the lifting device in an open position, where a central plane P is illustrated.
  • the imaginary central plane P extends in a longitudinal or length direction L and height direction H and is defined as the plane where the respective forces exerted by the lifting arm and the adjustment arm are balanced.
  • the central plane P intersects the sledge guide 16 in the middle of the width of the sledge guide 16.
  • the width is defined as extending in the width direction, the width direction being perpendicular to the length direction.
  • the two lifting arms 141, 142 are therefore symmetrically arranged with respect to a central plane P.
  • the sledge guide is shown as extending along the length direction that defines the central plane P.
  • the lifting device is shown in an open position and the lifting arm extends substantially in the height direction in this open position.
  • the lifting arm When the lifting device 10 is in the closed position, such as shown in Fig. 3A , the lifting arm extends substantially along the length direction together with the sledge guide.
  • the two adjustment arms 521, 522 are symmetrically arranged with respect to the central plane P.
  • the two lifting arms 141, 142 are positioned such that the forces exerted by the lifting arm 14 onto the central plane P are balanced.
  • the sledge guide 16 is symmetrical with respect to the central plane P.
  • the lifting arm 14 comprises a first lifting arm 141 and a second lifting arm 142 arranged symmetrically with respect to the central plane P.
  • Figs. 10 and 11 show a lifting device from a side view.
  • the adjustment arm 52 is adjusted such that its second end is in a position creating an angle ⁇ 1 between the lifting arm 14 and the adjustment arm when the window is in an open position.
  • Fig. 11 the roof window is in the same open position as in Fig. 10 and the second end of the adjustment arm 52 is adjusted such that the angle between the adjustment arm 52 and the lifting arm 14 is an angle ⁇ 2 .
  • Fig. 11 it is also visualized how the adjustment arm 52 can be adjusted by means of a mechanical tool 60 such as a drill bit fitted and rotated into an opening 161 in the sledge guide 16 of the lifting device 10, also shown in Figs. 2 , 3 .
  • the adjustment arm 52 shown in Fig. 10 is arranged for a roof window installed in a roof with an inclination of approximately 65°
  • the roof window shown in Fig. 11 is arranged for a roof window installed in a roof with an inclination of approximately 15°.
  • the adjustment arm 52 By adjusting the adjustment arm 52 to a position in between these two extremes the forces can be balanced for roof inclinations varying in the range of 15° to 65°.
  • the adjustment system may also adjust the lifting device to operate smoothly in roof windows installed in lower or higher roof inclinations, such as 10° or 70°.
  • Figs. 12A - 12B show an example of how a mechanical tool and an adjustment system may interact.
  • a mechanical tool 60 is shown to fit into the opening 161 of the sledge guide 16.
