  • the top surface of the front end of the flange 106 flushes with the top surface of the bottom sash part flange 106'.
  • the outer edge 106b of the flange 106 at the side sash parts 103 is higher than the inner part where the flange is connected to the exterior surface 105 of the sash part, so as to form a drainage groove 107 at the side parts of the sash.
  • the groove 107 on the top surface of the flange 106 shown in Fig. 3 is formed in the top surface of the flange 106, with the outer portion of the flange being higher than the inner portion.
  • the drainage groove may be a separate groove part fixed onto the top surface of the flange.
  • the cross section of the drainage groove is U-shaped, V-shaped, curved or the combination thereof or other shaped, as long as it can drain water.
  • the flange 106 of the top sash part 102 forms a water groove, whose outer edge is higher in level than the inner edge due to the tilting. Therefore, the water can flow to the drainage groove 107 of the flange on the exterior surface of the side sash parts 103.
  • the water can be contained by the flange 106 when it flows there, in particular when there is drainage groove 107 as shown in the figure on the top surface of the flange, since the water dripping down from the exterior side of the sash is of small quantity.
  • the water flows to the bottom sash part 104 along the flange and the groove. Then, the water drips down from the front edge of the flange 106' of the bottom sash part, along the downward folding edge mounted at the bottom covering of the sash, onto a flashing part. Since the flange 106' of the bottom sash part covers the top surface of the bottom window-frame part and extends above the frame, the water cannot flow in the bottom frame part, and thus cannot enter the gap between the bottom sash part and the bottom frame part.
  • the flange 106 Due to the drainage of the flange 106, it can drain the water in the gap between the sash and the window frame and drip down along the sash, stop the water from flowing further below the flange and entering the house. Consequently, it prevents the water or moisture from eroding the wooden members.
  • the space 300 can be used to install a servo lifting device or hinge for the roof window. Not only can they be installed easily since the space is large, but also since these devices are fixed above the flange 106. After being installed, they are not visible from indoor. Therefore, the installation does not affect the appearance of the window.
  • a surrounding groove 200 formed, which is used to receive a sealing element 310, so as to seal between the sash frame 100 and with the corner 306 of the window frame 1 when the window is closed, as shown in Figs. 5 and 6, so as to prevent wind and rain from entering the gap between the sash and the frame.
  • the groove 200 may be located at the underside of the flange 106 and thus open downward, or it may be located at the exterior surface 105 and adjacent below the flange 106, depending on the type and of the sealing element used The particular situation will be described in the flowing embodiment.
  • grooves 201, 202 at the underside of the flange 106, 106' of the bottom sash part 104 which are parallel to the groove 200 provided at the underside of the flange for mounting the sealing element.
  • the groove 200 below the flange 106 of the two side sash parts 103 extends forward across the two parallel grooves 201, 202.
  • three sealing elements are together provided to form a sealed space with a better sealing; and on the other hand, the sealing elements may be formed into a single piece, which can be fixed easily below the entire flange 106 and 106'.
  • the number of the grooves formed in the underside of the flange 106' can be one or more than one.
  • a groove 203 formed facing downward.
  • the groove 203 is parallel to the sash bottom part 104. It is used to receive and fix a sealing element so as to seal between the interior surfaces of the sash frame and the window frame.
  • these sealing grooves 200, 201, 202, 203 packed with sealing elements can provide noise and dust insulation. Because the cold air outside the house cannot enter the room through the gap between the window frame and the sash, the vapor inside does not condense into dew or frost at the gap. These designs are particular advantageous in wooden window structure.
  • This embodiment uses a wood and PUR composite material, which consists of a core made from plywood and a cover made from a PUR layer for covering the core fully and partially. Since wood is a good heat-insulation material and is not expensive, while PUR is a good water-resisting material and is ligh, the composite material has the advantages of low cost, light weigh and water-resisting. This material can be produced by plastic molding processes, so as to form a single-piece sash frame, without any seam. The PUR may be coated with other materials.
  • this embodiment relates to a preferred embodiment of a sash frame for a roof window according to the invention.
  • this embodiment is similar to the first embodiment, and therefore, uses the same numeric identifiers for the same parts or structures.
  • the top surface of the bottom part 404 of the window frame 400 is lower than the top surface of the side parts 403, while the flange 406 corresponds to the flange 106 formed at the exterior surface of the sash.

  • a sealing element 310 is mounted in a surrounding groove 200 below the sash flange, by inserting the sealing element 310 into the groove 200, so that the sealing element 310 is fixed at the sash 100.
  • An O-sealing element 311 seals the substantially horizontal interface between the flange 406 of the interior window-frame surface and the flange 106 of the exterior sash surface.
  • One side portion of the sealing element seals a substantially vertical gap between these two flanges.
  • Fasteners such as nails are used to fix the sealing element on the sash to prevent it from coming out of the groove 200 when the window is opened or closed.
  • the underside of the flange 106' of the bottom sash part 104 is above the top surface of the bottom frame part 404, and the front end of the sash extends forward from the bottom frame part 404, so that the water on the top surface and the flange 106' of the sash can bypass the bottom frame part 404 and be discharged directly to the flashing part (not shown) of the roof window via the bottom covering 154.
  • the space 300 above the sash flange 106 is used to mount a servo lifting device and a hinge device (not shown).
  • the underside of the protruding part 106' of the bottom sash part 104 has two grooves 201, 202 for receiving two sealing elements (not shown) respectively.
  • the sealing elements are inserted into the grooves 201, 202 or the flange described above and fixed into the sash. They seal the gap between the bottom parts of the window frame and the sash.
  • Four sealing elements are used to seal the gap between the window frame and thus prevent wind, rain, snow, dust and noise from entering the house. Since cold air is blocked, there is no condensed water such as dew or frost.
  • Vacuum or insulation glass 500 is fixed on the sash by four sash covering fixed on the sash by screws, i.e. the top sash covering 152, the side sash coverings 153 and the bottom sash covering 154.

  • the exterior edge of the sash side coverings 153 bends down and exceeds a vertical plate of the frame side coverings 453, so as to make sure the rain and dew drips down along the frame covering.
  • the coverings are also used to cover the gap between the window frame and the sash, to prevent the rain from entering the gap.
  • the first covering 501 is fixed at the top part 402 of the window frame, while the second covering 502 is fixed at the top part 102 of the sash.
  • the first covering is hooked with the second covering, so they can rotate relative to each other when the window opens.
  • the purpose of the top covering is to prevent water from entering the top gap between the window frame and the sash.
  • a flange 6 protruding forward is located at the top of a sash 1.
  • the flange 6 extends above the top surface of a frame 2 and forms a connecting surface 5 between the flange and the top surface of the sash.
  • a convex platform 7 is on the interior surface of the frame 2.
  • Another connecting surface is formed by the top surface of the convex platform 7 and the corresponding surface of the sash.
  • a groove 9 opening downward is on the surface of the sash part.
  • a sealing strip 8 is mounted inside the groove 9. The sealing strip 8 seals between the top surface of the convex platform 7 and the corresponding sash surfaces.
  • the grooves 3 there are three grooves 3 at the bottom surface of the flange 6 protruding forward from the sash 1.
  • the grooves 3 extend along the length direction of the sash.
  • a sealing strip 4 is mounted inside the groove 3 at the corner of the flange and the exterior surface of the bottom sash part. Referring to fig.2, the sealing strip has a flange 10 along its length direction. The flange 10 inserts into the grooves 3, 9.
  • the sealing strip also has an O-shaped sealing edge 11 and a wing-shaped sealing edge 12. The O-shaped sealing edge has a better elasticity, . When being pressed to the frame 2 by the sash 1, it can effectively seal the gap between the two.
  • Two sealing strips 4, 8 are mounted in the grooves 3, 9 at the comer.
  • the sealing strips When the window closes, they are pressed by the two surfaces of the sash, so the sealing strips are pressed tightly and stick to the frame, thus achieve a better sealing effect. Also the sealing strips are difficult to move when being pressed, plus being nailed to the frame 1 by the nail (not shown), so the sealing strips won't fall off easily.
  • the two ends of the grooves are connected, thus not only three sealing structures are formed by mounting sealing strip of one integrated structure, but also two closed sealing spaces are formed among the three sealing strips. Therefore, it achieves a better sealing effect.
  • the sealing strip is not mounted in the two preceding grooves 3, but due to the two grooves at the connecting surface between the sash 1 and the frame 2, the wind or sound wave that enters here will be depressurized by the two grooves. So the air or sound wave that further enters the gap will be weakened, thus a certain wind resistant and sound insulating effect can be still achieved.
  • the sealing effect of the groove 3 and two sealing strips 4, 8 Due to the sealing effect of the groove 3 and two sealing strips 4, 8, even strong wind can not blow into through the gap between the sash and the frame, so that rain and dust are impossible to be brought in either. At the same time, the spread of the sound wave is blocked, so the noise reduction is achieved.
  • the closed space formed by the sealing strips 4 and 8 has a strong effect of heat insulating, and sound insulating, so that the temperature indoor at the gap of the window won't be too low, further preventing the condensation and the frost.
  • the groove for mounting the sealing strip can be placed at the corresponding place of the frame. Also the position and quantity of the sealing strips can be changed according to the actual situation.
