Definitions

  • the present invention relates to a roof window having a frame and a sash, each having a top member, a bottom member and two side members, the sash being pivotally connected to the frame so that a pivotal opening movement of the sash in relation to the frame moves the window between a closed position and a fully opened position, wherein the window comprises a pressure spring, the pressure spring over at least a part of the opening movement pushing the sash against the fully opened position of the window, the pressure spring at a first position being rotatably attached to a first of the side sash members.
  • Roof windows of this kind are often used for providing ventilation of air, heat or smoke, so that a free airflow may be obtained in a building where a ventilation mechanism is necessary.
  • a ventilation mechanism is necessary.
  • the window should be arranged such as to automatically open during for example a fire.
  • it is generally known to provide the windows with an auxiliary opening device.
  • a typical auxiliary opening device takes the form of a pressure spring, such as for example a gas spring, provided on either one or both sides of the window structure and connecting a side frame member with a side sash member.
  • the pressure spring provides a spring force pushing the frame and sash members away from each other, thus forcing the window towards an open position.
  • the pressure spring In order to close the window it is necessary to manually or automatically, for example by means of a chain operator, pull the window sash towards the window frame, where in a closed position, the pressure spring lies substantially parallel to the window frame.
  • a window of this kind is described in Applicant's European Patent No. EP 1 508 663 , which discloses a pivotal roof window having an auxiliary opening device, such as a pressure spring, which in one end is connected to the sash of the window and in the other is connected to the frame.
  • the auxiliary opening device has the function to provide a supplementary torque that helps to rotate the sash with respect to the frame during the opening movement.
  • This prior art construction of a pressure spring causes the side frame and side sash members to which the pressure spring is attached to be subjected to large forces.
  • the pressure spring in both the open and closed position of the window therefore exerts large constant forces on the side sash and side frame members, which are thus subjected to stress loads that cause the window frame and sash members to be off-set in relation to each other, which has several drawbacks, including deterioration of the window's insulation properties.
  • the forces exerted from the pressure spring may damage and/or deform the window over time, which may entail that the window can no longer be opened, causing a need for repair or replacement.
  • pressure springs are often arranged so that the forces exerted during the opening movement, in the beginning thereof, work against the opening movement of the window thus creating a stronger force to overcome during opening of the window.
  • pressure springs of such installations are often connected to one or both of the side frame or sash members in a way so that the pivotal movement of the window during the opening movement causes the pressure spring to turn in a manner so as to extend on the interior side of the frame which may create an undesirable aesthetic appearance of the window in the building in which the window is installed.
  • the window according to the present invention is characterized in that the pressure spring at a second position is rotatably attached to an arm, and the arm at a third position is rotatably attached to the first of the side sash members and at a fourth position is rotatably attached to a foot, the foot being connected to a first of the side frame members, which is associated with the first side sash member, such as to be able to move in a longitudinal direction of the first side frame member during said opening movement, said longitudinal direction extending from the bottom frame member towards the top frame member.
  • the inventor has realized that in the above described prior art roof window forces exerted by the pressure spring on the sash and frame may be alleviated by in practice making the point of attachment between the pressure spring and the frame movable or slidable in the longitudinal direction.
  • the pressure spring is arranged in the window so as to lessen or substantially neutralize any component of force not working to push the sash towards the fully opened position during the opening movement.
  • This is achieved by the free movement of the foot, which is indirectly connected with the pressure spring via the arm.
  • the free movement of the foot in the longitudinal direction has the effect of substantially neutralizing any component of force exerted by the pressure spring in the longitudinal direction. This ensures that any components of force in the longitudinal direction are neutralized as soon as the foot moves or slides a distance in the longitudinal direction.
  • the frame and sash will less likely be off-set in relation to each other and/or deformed over time.
  • the second position is located between and at a distance from each of the third and fourth positions, so that the pressure spring in this way at the second position is rotatably attached to the arm at a position thereof, and that the pressure spring moves approximately in the same direction as the arm during parts of the opening movement.
  • the second position is preferably positioned with equal distance to the third and fourth positions, but could also be closer to one of the third or fourth positions.
  • the second position is not positioned closer to any one of the third and fourth positions than one third of the distance between the third and fourth positions.
  • the first to fourth positions are each configured as rotary joints, each with a rotation axis extending substantially perpendicularly to said longitudinal direction, thus providing an axis of rotation corresponding to the direction of opening of the sash during the opening movement.
  • the first and second positions in said closed position are located so that said pressure spring is arranged to extend in said longitudinal direction and in parallel with said arm.
  • said positions seen from the bottom frame member towards the top frame member are arranged in the order first, fourth, second and third.
  • the arm and the pressure spring are arranged so that a length direction of the pressure spring is arranged to be parallel with the arm, thus providing an optimal configuration where the foot is able to absorb the forces exerted on the sash and frame members when the window is in the closed position. Furthermore this arrangement has the effect that it is possible to close the window entirely.
  • the location of the second and fourth positions may be so that the second position during a first part of the opening movement moves in said longitudinal direction along the side frame member towards the bottom frame member and in a second, subsequent part of the opening movement also moves in a direction away from the side frame member towards the side sash member, and the fourth position during the entire said opening movement moves in said longitudinal direction along the side frame member towards the bottom frame member, the arm in said fully opened position extending at an angle to the longitudinal direction of the side frame member.
  • the foot is configured to move freely along said longitudinal direction during the entire opening movement, thus neutralizing the forces exerted by the pressure spring in all positions of the window.
  • the foot is configured to slide in the longitudinal direction with a foot slide surface sliding on a frame slide surface of the first side frame member during the opening movement, thus creating a minimum need of materials to arrange the foot in a slidable manner at the side frame member.
  • the first side frame member comprises a rail extending in said longitudinal direction, the rail being configured to guide the foot in said longitudinal direction during said opening movement, thus providing the foot with a guiding element, so that the direction of movement does not diverge from the longitudinal direction of movement.
  • the rail may in a further development of this embodiment comprise the foot slide surface and an abutment surface supporting the foot in a direction perpendicular to the longitudinal direction of said frame member.
  • the rail is provided as an integral U-shaped groove in the first frame member, the groove comprising a foot slide surface and an opposing abutment surface, said foot slide surface and said abutment surface connected by a connection portion guiding said foot to move in said longitudinal direction.
  • the rail provided as a single abutment surface or as an integral groove of the side frame member, provides a guide for the foot, the abutment surface simply keeping the foot in place on the side frame member by a force exerted on the foot transverse to the longitudinal direction.
  • the integral groove in a further development provides extra holding means for the foot, so that it will not risk being displaced during the opening movement.
  • the roof window may be symmetrical so that a second of the side frame members and a second of the side sash members opposing said first side frame and side sash members of said window are connected by a corresponding mirrored pressure spring arrangement with an arm and a foot.
  • the opening of the window may be assisted by two identical or similar, opposed pressure spring arrangements, both arranged on the window according to the present invention, so that no forces are exerted on any of the frame and sash members.
  • damage or deformation of the window structure is prevented.
  • the arm may in any embodiment be a substantially straight rod, and the pressure spring could for example be a hydraulic spring and/or a gas spring.
  • Fig. 1 illustrates a prior art roof window comprising a frame 1 with a first and a second pair of mutually opposite frame members.
  • the first pair consists of a top member 3 and a bottom member 4.
  • the second pair consists of side members 5 and 6, each extending between the top and bottom members 3 and 4 to form a substantially rectangular frame 1 intended to be build-in into e.g. an inclined roof (not shown).
  • the inclination may be defined by the roof pitch, which for example could be in the range 15-55° with respect to a horizontal plane.
  • a sash generally designated 2 is constructed in a similar manner with a top member 7, a bottom member 8 and side members 9, 10 forming a rectangular sash 2.
  • a rectangular window pane 11 of any type, e.g. an insulating unit, is encased.
  • the sash 2 is connected with the frame 1 by means of a hinge device, which comprises a set of hinges, of which one hinge 12 is shown in Fig. 1 , at corresponding side members 5 and 9, and 6 and 10, respectively, of the frame 1 and sash 2.
  • the set of hinges may be designed in any suitable manner.
  • a pivot hinge connecting the frame and sash members makes it possible to establish an overlap between the sash and the frame in the closed position of the window as well as creating the possibility of pivoting the roof window almost 180 degrees for example for cleaning purposes.
  • Fig. 2 shows a side view of an embodiment of the window according to the invention having a frame 101 and a sash 102 arranged in a not shown inclined roof similar to the prior art window of Fig. 1 .
  • the frame 101 and the sash 102 each have a respective top member 103, 107, a bottom member 104, 108 and two side members 105, 109 (only one side member shown in Figs 2 to 4 ).
  • the frame 101 and the sash 102 are arranged so that the sash 102 is pivotally connected to the frame 101, so that a pivotal opening movement of the sash 102 in relation to the frame 101 moves the window between a closed position and a fully opened position.
  • the fully opened position is a position where the sash 102 is pivoted relative to the frame 101, and the pressure spring 106 is extended, for example the sash may be pivoted substantially perpendicular to the frame.
  • the window is centre hanged i.e. the axis of the pivot hinges 112 lies substantially halfway on the sash 102.
  • the pivotal connection is known in the art to be provided for example by use of a set of two pivot hinges 112 providing a combined hinge axis as described in the above.

  • the pressure spring 106 is at a first position A rotatably attached to a first of the side sash members 109 and at a second position B rotatably attached to an arm 111; the arm 111 at a third position C is rotatably attached to the side sash member 109 and at a fourth position D rotatably attached to a foot 110.
  • the arm 111 takes the form of a straight rod.
  • the foot 110 is connected to a first of the side frame members 105, which is associated with the first side sash member 109, so as to be able to move in a longitudinal direction L illustrated by the dotted line in Fig. 2 and extending from the bottom frame member 104 towards the top frame member 103.
