Definitions

  • Each gas spring is typically secured to both of the respective frame and sash members from the factory manufacture to ensure that they are positioned properly. This means that the window frame and window sash are delivered connected to each other, resulting in a heavy structure, which is difficult to handle during mounting, especially when mounting the window from the roof side. Further, it is difficult to carry out maintenance, such as changing the chain operator, from the roof side because the gas springs must be detached from at least one of the sash and frame in order to open the window enough to provide access to the lower side of the window. After maintenance the springs must be reattached in their original positions.
  • said window further comprises a reinforcement member, preferably in the form of an oblong metallic rail, connecting points of attack of said compression springs on said window frame and/or sash, respectively, such as to absorb horizontal force components exerted by the compression springs on said window frame and/or window sash.
  • a reinforcement member preferably in the form of an oblong metallic rail, connecting points of attack of said compression springs on said window frame and/or sash, respectively, such as to absorb horizontal force components exerted by the compression springs on said window frame and/or window sash.
  • the bearing members 14, 15 are shaped to be embedded in corresponding cut-outs of the top sash member 3a and top frame member 4a, respectively, and are secured via screw bores 18.
  • Each bearing member is provided with similar oblong trays, of which only the tray 15a of the frame bearing member 15 is shown ( Figs 5 and 7 ).
  • the trays correspond to the hemispherical heads 18, 19 of the gas spring 11.
