Definitions

  • the present invention relates to a window frame, in particular a frame for a roof window.
  • the frame comprises a top member, two lateral members and a bottom member.
  • the frame may be hinged to a sash so that the window is openable, or it may be unopenable.
  • the invention also relates to a roof window.
  • a known roof window in particular an openable roof window, comprises a plurality of members.
  • International Publication WO99/51831 discloses an openable roof window comprises a frame, a sash, a glazing and a plurality of coverings. It is certainly favorable to manufacture windows and members in standard dimensions and sizes for interchangeability of members. Thus, it is beneficial to prepare packages for the members and replace one with another, which results in a reduced cost for storing and transporting the members.
  • the window may need a window screen to prevent the insects from entering the house.
  • the window screen needs to be installed on the frame by means of guide tracks.
  • the guide tracks are fastened to the bottom member, top member and lateral members of the frame.
  • the appearance of the window is not attractive. Certainly, it is hard to position and fasten the tracks precisely.
  • One purpose of the invention is to provide a window frame under standard specifications.
  • Another purpose of the invention is to provide a frame with a better appearance.
  • Still another purpose of the invention is to provide a frame, on which the window screen is easy to be installed. Therefore, the present invention provides A roof window frame comprising a top frame member, two lateral frame members and a bottom frame member, wherein said frame members form a rectangular-shaped structure, characterized in that the profile of the rectangular structure is of standard dimensions, and that at least one of the top and bottom members has an inclined inner surface extending inwards from the bottom surface edge of said at least one member towards the inside of the window frame and faced inwardly on the room when the frame is installed.
  • said inclined surface is a flat or/and curved surface. More preferably, the top and bottom members and/or the lateral members have an inclined outer surface.
  • the top and bottom members and/or the lateral members have at least two crossing outer surfaces. More preferably, the top and bottom members and/or the lateral members have a base edge around the window frame and the inclined surfaces are extending into the inner of the frame from the base edge. More preferably, the inclined surface on the outer surface of the frame is above the base edge. More preferably, the inclined surface on the outer surface of the frame is below the base edge. More preferably, the inclined surface on the outer surface of the frame is above and below the base edge. More preferably, an outer recess is formed around the bottom surface edge of the frame. More preferably, the outer recess is curved, L-shaped or V-shaped.
  • an inner recess is formed around the bottom surface edge of the frame to mount a curtain. More preferably, the inner recess is curved, L-shaped or V-shaped. More preferably, the frame is made from wood, stainless steel, or aluminum alloy, metal-plastic complex or other complex materials. More preferably, the frame consists of a wooden core and a PUR layer applied the core. More preferably, the wooden core is made of plywood. More preferably, a coating is applied to the PUR layer. More preferably, the frame that constitutes of lateral members and horizontal members is integral. More preferably, the frame is a one-piece structure.
  • the present invention also provides a roof window consisting of a window frame and a sash frame hinged on the frame and provided with a glazing and a covering, where the frame comprising two lateral members and two horizontal members which constitute one top member and one bottom member of the frame, wherein the window frame comprising a top frame member, two lateral frame members and a bottom frame member, wherein said frame members form a rectangular-shaped structure, characterized in that the profile of the rectangular structure is of standard dimensions, and that at least one of the top and bottom members has an inclined inner surface extending inwards from the bottom surface edge of said at least one member towards the inside of the window frame and faced inwardly on the room when the frame is installed.
  • Figs. 1 to 4 show schematically a preferred embodiment of a window frame according to the present invention.
  • the frame 1 comprises horizontal members consisting of a top frame member 2 and a bottom member 4, and two lateral frame members 3 extending parallel to a roof.
  • the ends of the lateral members 3 are connected to the top member 2 and the bottom member 4, as shown in Fig. 1, the top member 2, lateral members 3 and bottom member 4 of the frame 1 comprises a one-piece structure produced by means of demolding processes.
  • the frame can consists of separate members then assembled together according to the present invention.
  • the members may be made from wood, plastic-steel complex, stainless steel and aluminum alloy or other materials.
  • the first step is to produce the frame members, i.e. top member 2, bottom member 4 and two lateral members 3, and then engage and fix them together at the second step. It is necessary to machine different materials or members.
  • the frame can also be assembled by two L-shaped frame members, or a U-shaped member and a linear frame member.
  • a base edge 5 around the entire frame including the top member 2, bottom member 4 and lateral members 3.
  • the length and the width of the rectangle formed by the overall base edge 5 match a standard sized window.
  • the base edge makes the frame structure easily engage and ideally cooperate with a standard drainage member (not shown) produced by the same production company or a different production company, and also makes the frame match the standard window recess constructed in the roof. This feature is very advantageous and important to the design, production, assembling and installation of the product.
  • the top surface 21 and the bottom surface 22 of the top member 2 are flat surfaces substantially parallel to each other.
  • the inner surface 23 of the top member 2 has a flange 24 extending towards the inside space surrounded by the frame members.
  • the flange is used to support a sash and creates a seal structure with the sash.
  • a flange 44 protruding inward from and an inner inclined surface 45 at the inner surface of the bottom member 4, above and below the base edge 5 of the bottom member 4 being a top inclined surface 46 and a bottom inclined surface 47.
  • flanges 34 protruding inward from and inner inclined surfaces 35 at the inner surfaces of the two lateral members, above and below the base edge 5 being inclined surfaces 36, 37 inclined to the center of the frame member at the outer surface of the lateral members.
  • the frame is made from a complex material comprising a wooden core 302 made from cheap plywood.
  • a PUR layer 301 covers the wooden core.
  • the PUR layer 301 is extruded onto the wooded core 302 by means of plastic foaming processes.
  • the wooden core 302 may be replaced by a hollow aluminum alloy member.
  • the complex frame has the same cost and weight level as a wooden one, while being wind-resistant and rain proofing far better than the wooden one.
  • the frame may entirely be made of wood, but the wood tends to erode when exposed to rain and sunshine.
  • a paint coating can protect the wood to a certain degree, but the paint can be peeled off gradually.
  • the wooden frame will inevitably crack some time, which will also affect the normal use and the appearance of the window. It also another choice to use aluminum alloy, stainless steel, plastic-steel complex or other complex materials, which would cost much more than using wood-PUR complex material according to the preferred embodiment.
  • the frame can be painted depending on actual applications.
  • the PUR-wooden frame of the embodiment is produced by plastic molding processes.
  • the inclinations reduce substantially the cross section of the frame members, so that compared with the prior parallelogram frame structure, the inclinations can considerably save materials for making a frame while ensuring the structural strength of the frame, and the extruded base edge 5 at the outer surface of the frame meets the dimensional specifications of a standard window frame.
  • the reduced material will lower the production cost and the product weight, which leads to a reduced transportation cost and facilitates the assembling and installation of the frame with a sash or other members into a roof.
  • the complex frame is a one-piece structure made by plastic molding processes, the inner inclined surfaces 25, 35, 45 and the outer inclined surfaces 27, 37, 47 will facilitate the demolding process.
  • a recess 29, 39, 49 around the inner surface of the entire frame.
  • the recess 29, 39, 49 is L-shaped for installing guide tracks (not shown) or other window screen members.
  • the screen can be mounted into the inner recess 29, 39, 49 via the guide tracks.
  • the guide tracks or the frame members can be easily and precisely fixed on the window frame for installing the window screen.
  • the depth and the width of the inner recess 29, 39, 49 can be designed depending on the width of the guide tracks and the entire bottom surface of the frame, which makes it possible to standardize the design of the window screen, to increase the compatibility of the screen and to ensure the installation precision of the screen.
  • this inner recess can be also used to install a standard curtain. It will be appreciated that such a recess is only formed in the lateral members or in the top member or bottom member, depending on the screen structure and the fixing device for the screen.
  • the recess 28, 38, 48 is L-shaped, so that when the window frame is installed into a sloped roof, a decorating casing for the window is mounted between the sloped roof window and the house wall and enter into the recess 28, 38, 48 vertically.
  • the window casing and the frame recess are engaged tightly with each other, and sealed together by applying adhesive to the recess. The engagement is tight and fast, and even if it begins cracking, the cracking will develop straightly, which will not affect the decency of the window.
  • the outer recess also saves materials for making a frame and facilitates the demolding process during the plastic injection and molding processes.
  • the transparent opening of the frame is increased.
  • the enhancement is substantial. Since the sunshine always projects onto the window non-vertically, due to the existence of the inclined surface, the lighting opening of the frame with the inner inclined surfaces 25, 45 is larger than that of a conventional frame without such inclined surfaces, and has an improved lighting efficiency.
  • the angle between the inner inclined surfaces 25, 45 of the frame and the inner surface of the roof becomes smaller, which facilitates the ventilation of the house.
  • the inner surface 45 of the bottom member 4 does not tend to adhere condensate water even when the temperature difference is considerable.
  • Fig. 6 is a perspective view of another sloped-roof window according to the invention.
  • the roof window consists of a frame 1 and a sash.
  • Hollow panes 400 are mounted in the sash through a sash covering 200.
  • a frame covering 100 is installed on the frame 1 and then engaged with a flashing member (not shown).
  • the frame 1 is characterized similarly to the first embodiment, comprising similar inner/outer
