A WINDOW CONSTRUCTION

Abstract: A window construction comprises a framed glass pane (1), whereby the framing is formed by a sash (2) sealingly abutting the edge zone of one side of the pane, the sash being pressed or pulled against the pane by means of clips or clamp strips (3) gripping over the edges of the pane.

Description: Title: A Window Construction Technical Field The invention relates to a window construction comprising a frame or parts of a gap in a wall, which serve as a frame, as well as a framed glass pane capable of closely abutting said frame or parts and being either fixedly mounted or mounted so as to be opened. Background Art Window constructions of the above type are generally known. As a result of the development glass panes have grown still heavier partly because the desires are directed to greater windows and partly - and perhaps mainly - because it is now often a question. of windows of several layers of glass with air therebetween, i.e. the so-called insulating panes. The increased weight and thickness of ' the glass panes involve increased and different requirements to the dimensions, the type, and the profiling of the framing material, which inter alia has caused very heavy glass framings. Disclosure of Invention The window construction according to the invention is characterised in that the framing of the pane comprises a corner joined sash of cold bridge-breaking material such as wood or plastics and extending in a plane substantially parallel to and outside the glass pane, as well as clips or interconnected clamp strips preferably of steel or aluminium and being of a substandially U- shaped gripping cross section and pressed over the edges of the pane, said clips or clamp strips pressing the sash towards the edge zone of one side of the pane con- tinuously along all edges of the pane, whereby a sealing and/or pressure relief, if necessary, are established at the surface of the pane by inserting a resilient, sealing intermediary layer such as a resilient joint filler or a resilient joint tape between the edge zone of the pane and the sash. The characteristic features of the above framing of the pane are consequently that the sash is retained closely to the edge zone of the pane at the side of the glass pane facing the frame by means of the clips or the clamp strips and further that the sash can form a sealing abutment against the frame. The sash need not absorb forces from the weight of the pane and can thus be rather slender. When the framing of the pane is to be mounted on the pane, " the sash is placed on the pane while simul¬ taneously covering the edge zone of one side of the pane, optionally the sealing, resilient intermediary layer being placed between the sash and the pane. Subsequently, the sash is pressed into abutment against the pane by means of the clips or the clamp strips, the U-shaped cross section of the latter being pressed over the edge of the pane so as to grip over the edge of the pane and portions of the sash. As a result, these parts are kept assembled. In order to prevent the clips or the clamp strips from destroying the pane, a sealing resilient intermediary layer may, as mentioned, be inserted between the pane and the clips/the clamp strips. This intermediary layer may for instance be made of plastics or rubber. In this manner the parts of the framing absorbing the forces from the weight of the pane and optionally trans¬ ferring said forces to functional fittings are positively positioned either on the cold or the warm side of the abutment of the sash against the frame. As a result, the problems of the cold bridges, if any, are avoided, said cold bridges often arising in connection with attemps to manufacturing pane framings of metal. Furthermore, an almost complete freedom as to production and design is obtained because the sealing abutment between the frame and the sash in principle is independent of the struc- 5 ture of the metal members and of their possible inter¬ connection. By "clip" should be understood a clamp strip or clamp strip-like member, which is short or relatively short. A simple framing of the pane is according to the inven- 0 tion provided by producing a sash of wood shaped and dimensioned in such a manner that it can cover 15-20 mm of the edge zone of the pane and may have a circumferential groove parallel to the plane of the pane and fonred in the radially outward edge surface of 15 the sash. The sash is placed on the pane, a resilient sealing mass being applied in advance between the sash and the glass. Subsequently, U-profiles are inserted, for instance steel profiles bent of o.5- 1 mm thick steel pliable sheeting, into the circumferen- 20 tial groove of the sash in such a manner that the U-pro¬ files grip over the edge zone of the pane relative to the opposite side of the sash. The U-profiles are mutually fixed in the corners by means of fittings or through a direct joining by means of rivets or screws. Finally, 25 plastic or rubber strips are inserted between the U-pro¬ files and the glass on the side of the pane opposite the sash. The framing of the pane has thus been completely established. The completion of the above concerns a strengthening or a particularly aesthetic design which, -.-0 however, is beyond the scope of the present application. According to a particular embodiment the sash is made of L-shaped PVC-profile, said L-profile being assembled through corner weldings to form the sash. The welding together of the L-profiles is carried out in such a 35 manner that one outer side of the L-profiles abuts the the edge zone of the glass pane and the other side faces the centre of the pane. In this manner one leg of the L-profiles extends from the plane of the pane at a short distance from the edges of the pane. As a result, it is possible to form a labyrinthic seal through the coopera¬ tion of the glass pane with the frame because abutment can be established both at the end of the projecting profile portion and on the clamp strip facing backwards relative thereto and abutting the leg of the L-profile which abuts the edge zone of the pane. Such an embodi¬ ment is particularly suited for inward windows as the mounting of a closing device allowing an outward open¬ ing of the window would present problems. Brief Description of Drawings The invention will be described below with reference to the accompanying drawing, in which Fig. 1 is a sectional view of a portion of a first embodi¬ ment of the window according to the invention, the pane framing being particularly simple. Fig. 2 is a sectional view through another embodiment of the window where the sash is an e-xtruded profile for labyrinthic sealing, and Fig. 3 is a horizontal sectional view through a portion of a third embodiment of the window, where the sash is secured by screwing onto a profiled body of metal. Best Mode for Carrying Out the Invention Fig. 1 shows how in a particularly simple manner an in¬ sulating pane can be framed according to the invention, a sash 2 being mounted against the edge zone of the insulating pane 1. This sash is clamped towards the pane by means of clips or clamp strips 3, the clamp strip gripping into a groove 4 and extending to the opposite side of the edge 5 of the insulating pane, whereby a pressure relieving profile 6 is inserted between the pane and the clamp strip. Furthermore, a resilient sealing 7 is established in the zone between the sash 2 and the glass 1. The frame of the window is indicated through a dotted line 8. Fig. 2 illustrates in principle the same framing of the pane as Fig. 1, but with the alteration that the stop frame is made of extruded profiled bodies 9 of an L- cross section and for instance made of PVC. These pro¬ filed bodies are shaped so as together with the clamp strips 10 extending from corner to corner of the glass pane to form a labyrinthic sealing partly through stops against a frame portion opposite the ( ,end 11 of the L partly through sealing against a sealing strip 12 at the clamp strip 10. The cross section of the frame has been indicated through a dotted line 13. Fig. 3 illustrates a horizontal sectional view through a further framing of a pane provided with clamp strips. The sash 20 is here pressed against the edge zone of the pane by means of screws 15 partly extending into the sash 20 and partly through a web 16 of a metal clamp strip 16. This metal clamp strip extends along and abuts the "opposite" edge zone of the glass pane 17, a rubber relieving member 18 being inserted between the metal strip 16 and the glass pane 17. The frame has been shown with a dotted line 19.
