Description

  • The object of the invention is a welded thermoplastic frame for a roof window with an infill profile.
  • A skylight with at least one plastic frame was disclosed under patent GB2099899A . The skylight frame is made of stiles connected at frame corners using a welding method. Stiles of previously disclosed welded window frames include chambers and comprises a cross-sections which make it possible to weld their edges in frame corners whilst maintaining its tightness.
  • The invention relates to a window frame for a roof window, comprising a stiles with cross-sections which make it possible to weld them to one another. The window frame is constructed in a way which also ensures unhindered insertion and extraction of roof window sash seated on hinges in the window frame. When opening the roof window, its sash pivot around the horizontal axis so that sash lower stile is raised upwards above the window frame lower stile. Therefore, the sash lower stile moves in circular motion relative to the window frame, which requires a greater gap between the window frame and sash lower stiles than between the window frame and sash side stiles, where the sash side stiles move parallel relative to the window frame side stiles. As for aesthetic reasons the smallest possible gap between appropriate roof window frame and sash stiles is desired, an infill profile according to claim 1 was used which at least partially covers the gap in the lower section of the window and facilitates the aforementioned unhindered sash insertion and extraction into and out of the window frame and makes it possible to weld frame stiles together.
  • The window frame according to the invention is a frame comprising an upper stile, a lower stile and two side stiles. The frame stiles are made from plastic profiles which comprise their walls: an outer wall, an inner wall, a top wall and a bottom wall. Once the frame is installed in a roof opening, the outer wall of the frame stiles is at least partially flush with the roof structure, whereas its inner wall is facing towards the frame inner opening. The top wall and the bottom wall join the inner and outer walls together making a stile profile with inner chambers. Once installed on a roof, the frame bottom wall faces towards the interior, whereas the top wall is on the opposite side and is shielded from the outside by the window shielding profiles. Furthermore, the stile bottom wall comprises a lining groove for the edge of roof window lining. When welding frame stiles, essentially all their walls are joined to each other. The window frame stile chambers may include metal strengthening profiles, preferably at least partially flush with frame stile outer wall as well as insulation profiles. The window frame is designed for a window, and in particular a roof window which also includes an sash frame with a glass unit. The sash frame, referred to as the sash, is constructed out of an upper, a lower and two side stiles, which, when the window is in its closed position, are flush with corresponding window frame stiles according to the invention. The window frame comprises an infill profile, mounted to the lower stile inner wall. The infill profile is designed to fill the gap between the frame lower stile and lower stile of the sash which is ultimately to be seated in the said window frame. The infill profile is preferably made out of plastic and comprises a longitudinal edge and it is not longer than the frame stile to which it is attached. Once installed, at least one infill profile longitudinal edge is in the frame lower stile longitudinal socket, and the infill profile overlaps at least partially the sash lower stile or does not overlap the sash bottom stile when the window is closed. This stems from the position of the window frame lower stile longitudinal socket. The lower stile with an infill profile includes a latching cube attached to a strengthening plate in a chamber of that stile. The latching cube works with the roof window sash handle latch. The latching cube is partially seated on the infill profile or is fully seated on the infill profile.
  • For windows with a plastic window frame and stiles welded together, it is desirable for walls of joined stiles to be identical. Therefore, without changing the window frame lower style shape, but by mounting an infill profile on it, stiles of the frame window according to the invention can be welded together and a sash may be seated in that frame, which is inserted and extracted unhindered into and out of the window frame when closing and opening the roof window. The infill profile also ensures that the gap between the sash and the jamb is as small as possible and preferably the same from all sides in the window closed position, and the latching cube seated at least partially on the infill profile makes it possible to lock the sash in the window frame. As the latching cube overlaps the infill profile, this invention may be used in particular for small windows for which the radius of the circle constituting sash extraction path from the window frame is smaller than for larger windows. That requires a larger gap between sash and window frame lower stiles and a larger infill profile, and connecting the latching cube with the infill profile provides such an opportunity whilst at the same time making it possible to lock the sash in the window frame by latching the handle in the latching cube.
  • The illustration depicts the solution, with given figures showing the following: Fig. 1 lower stile with infill profile, Fig. 2 spatial view of window frame, Fig. 3 top view of window frame.
  • The plastic window frame comprising an upper stile 1, a side stiles 2 and a lower stile 3. Each stile comprising an outer wall 31, an inner wall 32, joining a top wall 33 and a bottom wall 34 with chambers 4 in between stile walls. Stile wall edges are welded to each other. Frame lower stile 3 additionally comprises an infill profile 5 seated in longitudinal grooves 321, 322 of inner wall 32. Frame stile chambers 4 house strengthening profiles 6 and insulation profiles 10. Latching cube 7 is in infill profile 5 and lower stile inner wall 32, it is attached to a plate and strengthens the inside of frame lower stile 3. The latching cube works with sash 11 handle latch designed to be seated in a window frame. Whilst opening the window, sash 111 lower stile moves in circular motion relative to the window frame lower stile 3. Stile bottom walls 34 comprises a lining groove 341 for the interior lining around the window and window frame. The window also comprises a set of shielding profiles, with frame side stiles shielding profiles 8 seated on frame side stile 2 top wall. The window frame also includes ventilation channel 9 in upper stile 1. The ventilation channel terminates with vent 91 in upper stile 1 inner wall which constitutes the ventilation channel outlet. The ventilation channel inlet is in upper stile 1 top wall. The ventilation channel inlet is shielded by the window frame hood which is one of the shielding profiles from the set of profiles shielding the window with frame according to the invention.
