A COUPLED WINDOW

Abstract: An opening, coupled window consists of two independently sashed glass panes which can be opened with respect to each other through mutual hinges and can moreover be opened together with respect to a frame or a wall opening through another set of hinges. In the coupled window of the invention the two independently sashed glass panes are connected to hinge fittings which simultaneously serve as hinge fittings for the opening function of the window with respect to the frame or wall opening. The hinge fittings, which are formed with means -holes or pins- (2) for opening with respect to the frame, are adapted in pairs to extend along and engage two opposite, parallel edges of the one sashed glass pane and are moreover provided with fitting parts, which extend toward the second sashed glass pane and are formed with means -holes or pins- (4) for the mounting thereof, said second sashed glass pane being provided with fitting parts for cooperation with the common hinge fittings.

Description: A coupled window The invention relates to a coupled window which consists of two independently sashed glass panes mutually mounted on common hinge fittings which simultaneously serve as hinge fittings for the opening function of the overall structure . Coupled windows of this type are known, where the two sashed glass panes are coupled together with flap hinges mutually secured in facing sash parts, and where the opening function of the coupled glass sashes with respect to the frame is established with strong hinges secured partly to the frame, partly to the sash of the one glass pane. It is characteristic of these structures that the sash of the one glass pane is to absorb and neutralize the forces from the weight and opening function of the- overall structure, and the same sash is moreover to absorb the forces caused by the opening function between the two glass panes. The development toward the use of heavier glass panes - larger sizes, insulated multi-pane glazing, etc. - has increased the requirements made of the strength of the sash material, of the fittings and their mounting. Ithas been necessary to use glass sashes of stronger dimensions, and this has necessitated greater tolerances in the coaction with the opening and fixed parts of the window. The greater tolerances make new and greater demands on sealing strips as these must be able to expand within a larger area. Strong sealing strips per se apply a great pressure in the structure and thus contribute to creating a need for additional dimensioning of the sash material, hinges and closing mechanism. The coupled window of the invention is unique in that no forces are transferred from the sash of the one glass pane to the sash of the other glass pane. Either because of weight or opening functions. This provides great freedom in the selection of sash material, dimensioning and arrangement. Moreover, the structure makes it directly possible to shape the common hinge fittings so as to create a spacing between the sashes of the two glass panes in which an independent abutment sash can be inserted. The abutment sash is fixed with respect to the glass panes by perforation of the coupling fittings which join the two glass panes with respect to each other. The abutment sash makes it possible to effectively break cold bridges in structures where the sash material for the glass panes is aluminium, steel, etc. As no forces are to be transferred from the weight and • opening function of the glass panes to the abutment sash, there are no restrictions in the selection of material and construction of it. Thus, a very insulating embodiment of the abutment sash might consist in its being formed by corner-joined, hollow, thin-walled PVC-profiles filled with expanded foam. This abutment sash might moreover be formed with a soft lip in its abutment zones and thus constitute the final seal between the fixed and the opening parts of the window structure. A particular embodiment of the window structure of the invention might be that, in an inwardly opening, sid-e- hinged structure, the hinge fittings common to the glass panes extended along the horizontal edges of the internal glass pane, approximately in the entire width of the opening window part, thereby to form mounting means for a closing mechanism. That in the selection of material, construction and dimensioning of abutment sash and glass sashes no regard is to be had to the forces occurring in the coaction of the closing mechanism with fitting portions in the frame or adjoining building elements. The window structure of the invention will be explained more fully with reference to the drawing, in which fig. 1 shows a possible embodiment of hinge fittings, fig. 2 is an elevation view of a coupled, side-hinged window, seen from the hinge side, and fig. 3 is a horizontal section of an inwardly opening, side-hinged, coupled window of the invention. It appears from fig. 1 how hinge fittings for a side- hinged, opening, coupled window may be shaped, the fittings being formed by two U-profiles 1, which are e.g. bent in a 1.5 mm. iron sheet. The U-profiles are approximately adapted in a length corresponding to the width of the opening window. Holes are drilled at the ends through both flanges 2 and 3, and a plate section 4 with a hole 5 for rotatable cooperation with the glass pane which is not to be placed directly between the U-profiles is welded to the inside of one flange on each U-profile. The hole at one end of the U-profiles 2 is intended to receive a round bar 6 which acts as a shaft for the opening function of the window, said round bar being journalled at its ends in fixed bushings in the upper and lower frame or in adjoining building elements. The mutual spacing between the hinge fittings is ensured and given by the glass pane as this is screwed to the U-profiles with screws through the holes 7. The holes at the other end of the U-profiles 3 are intended to receive a closing mechanism for the coupled structure, said closing mechanism being formed as a through shaft 8 with holding means 9 at the ends to cooperate with fitting parts mounted in the frame or adjoining building elements. The closing mechanism is operated by the shown grib 17. The elevation in fig. 2 shows a side-hinged, coupled window seen from the hinge side, the sashed glass pane 10 being mounted between the hinge fi tings 11. It moreover appears from the elevation that the abutment sash 12 mounted between the glass panes extends radially outside the four edges of the glass pane. A through rod 6 is seen at one side of the glass pane, said rod being passed through the fittings and cooperating with bushings 13 which are mounted outside the opening part of the structure, e.g. in the frame. The bushings 13 are shown by broken lines in the drawing. Also, a rod 8 is shown at the side of the class pane opposite the hinge side, said rod extending through both hinge fittings and provided at its ends with holding means 9 to copperate with fitting parts firmly mounted in the frame 14. An operating grip 17 for the closing mechanism is shown as placed below the glass pane. It appears from fig. 3 how the abutment sash 12 is placed between the glass panes 15 and extends outside these. It moreover appears how the hinge fitting extends below the one glass pane. It also appears from fig. 3 how the shaft 6 and the through rod of the closing mechanism 8 are placed with respect to the abutment sash and the glass panes. The coupling between the two glass panes is shown partly by the hinge members 4 breaking through the abutment sash, partly by coupling fittings 16 which likewise break through the abutment sash. It is moreover shown in the figure how the cooperation with the frame 18 may be arranged, a sealing strip 19 being mounted in the abutment zone.
