Description

[0001] The present invention relates to a window or door assembly comprising a wooden frame provided with an external aluminium or plastic covering, a wooden sash with a glazing unit, a sealing arrangement and a fitting arrangement, which is apt for being employed in construction industry.

Background of the Invention

[0002] Various window or door assemblies known from the state of art have wooden frames and wooden sashes, both provided with external aluminium coverings. Since in this case both the frame and the sash have a relatively complicated construction, this results in an increased use of wood and thus in an increased production costs.

[0003] Patent publication PL401780 discloses a wooden window provided with an aluminium covering mounted at the external side of the window. The edges of a glazing unit are projected above a groove formed in a sash and additionally adhere to an insulation covering fastened at the external side of the sash. The second insulation covering is fastened at the external side of the window to the window frame. The insulation coverings are employed in order to improve thermal insulation.

[0004] Other known window assemblies have frameless constructions with glazing units fastened to an insert located between the panes and made of plastic.

[0005] Patent publication EP2436865 discloses a window in which the total thickness of a glazing unit equals the thickness of a window sash. The sash is entirely frameless, wherein the interior panes of the glazing unit are glued to a plastic insert located between the outermost panes that completely encompass the insert. The window frame is shifted on both sides relative to the sash, so that the total width of a window is relatively large. The shift of the frame relative to the sash also enforces an employment of a specific seal system between the sash and the window frame as well as an employment of specific fittings. The window frame is made of wood, aluminium, plastic or a combination thereof.

[0006] A similar window is known from the publication EP2816187 disclosing a frameless window sash, wherein the internal and the external panes in this window are glued to an insert located between them. The internal pane is coplanar with the outermost surface of the window frame. The window frame is covered at the external side of the window by aluminium covering which closes the space between the sash and the window frame.

[0007] All the above described constructions feature a common disadvantage of a relatively large width of a window which in turn induces an increase of material costs and difficulties in obtaining good thermal insulation parameters.

[0008] Therefore the object of the present invention was to provide a wooden window or door assembly that would enable to achieve material savings while maintaining an excellent thermal insulation and improved aesthetics of such a window or door.

Summary of the Invention

[0009] According to the present invention there is provided a window or door assembly comprising a wooden frame provided with an external aluminium or plastic covering, a wooden sash with a glazing unit having an internal pane and an external pane, a sealing arrangement and a fitting arrangement, wherein said internal pane is coplanar with the internal side of said wooden frame, characterized in that said wooden sash is fixed between said internal pane and said external pane of said glazing unit, wherein said internal pane of said glazing unit extends outside beyond the periphery of said wooden sash forming a projection that abuts the internal surface of said wooden frame and thus covers the internal space between said wooden sash and said wooden frame, while said external covering extends inside beyond the periphery of said wooden frame forming a projection that covers the external space between said wooden sash and said wooden frame, and the total width of said wooden frame and said external covering is close to the width of said glazing unit along the line perpendicular to said glazing unit.
