Description

The invention relates to a double glazed window with multiple glazing.

At present, triple glazed windows are used either with a single leaf with triple glazing or with a double or double leaf with a combination of double glazing and a single pane of glass, or with a triple-sided triple-wing structure carrying three single panes or double glazed window with a simple additional leaf using special hinges and couplings.

The disadvantages of the structures used so far are, in particular, the disproportionately high costs. In particular, alternatives with triple-glazing or double-glazing increase costs to such an extent that they are in many cases unusable despite a certain reduction in labor. The use of triple glazing or double glazing places increased demands on the glazing methods and in the case of damage to the triple glazing or double glazing due to leakage or destruction, the cost of repair, replacement is disproportionately high. The air gap width of technically feasible triple glazing or double glazing limits the achievable value of the heat transfer coefficient and the sound insulation index. Construction alternatives with triple sash are particularly disadvantageous for increased labor and material consumption.

The disadvantages of single-leaf construction are again increased costs, labor and accuracy requirements. Despite the diversity of the suspension and sealing principles, the additional wings always require either special hinges and couplings, or the use of metal or plastic flashing profiles or the use of tempered glass for safety reasons.

The above-mentioned drawbacks are eliminated by the double-glazed window according to the invention, which consists in that the inner pane of glass is detachably connected to the carrier leaf and the combined leaf by means of inserts and independent groups of connecting elements, e.g. of the elements mounted loosely in the support wing is connected from one side to the fastening insert, while the other group of fastening elements disposed freely in the associated wing of the double window is connected to the opposite side of one of the same fastening insert. According to a further feature, the heads of the two groups of connecting elements are situated on the outside of the carrier leaf and the combined wing of the double window and the mounting insert divided in a plane parallel to the face of the inner glass pane and consists of two or more parts interconnected by connecting elements intended to be connected inserts for the windows of the double window. It is also essential that the two wings of the double window, the carrier wing and the composite wing are provided with recesses having an internal shape identical to the external shape of the fastening inserts, the inserts extending into the recesses in both the wing, the supporting wing and the composite wing simultaneously.

The basic advantage of the double-glazed double glazing according to the invention is the achievement of triple glazing at considerably lower cost only by modifying the construction of existing double-glazed windows and thus without changing the conventional

96193 used technology of production. In case of destruction of any glass pane, the proposed structure allows its inexpensive replacement. The larger air gaps between the windows of the double window according to the invention provide a lower heat transfer coefficient and a higher airborne sound insulation index compared to triple glazing structures or a combination of double glazing and single glazing in a double wing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION The schematic drawing of the double glazed window according to the invention is shown in the accompanying drawings, in which: FIG. Fig. 4 shows the function of a double window when opening, Fig. 5 the state after unscrewing the group of screws fixing the inner pane to the composite wing, fig. 6 the state after the group of screws fixing the inner pane of the glass to the supporting 7 shows a plan view of FIG. 7, FIG. 9 shows the shape of the mutually identical parts of the split joint insert in a front view, FIG. 10 a side view of FIG. 9, FIG. 11 a plan view 9 and 12, in a spatially and unfolded state, the composition 7 and 8.

In the exemplary embodiment according to FIG. 1, the window consists of a carrier wing 4 and a wing associated therewith. Both wings are glazed on the outside with glass panes 4 and 4 with glazing putty. The glazing may be carried out by any other known method. The inner glass pane 8 on the perimeter covered with a microporous rubber profile 60 is fastened by means of fasteners 4 to the wing by means of screws 7 and further independently fastened by means of screws 8 to the associated wing 2. sash 4 and the sash 5 so that they normally perform the function of a double sash, see also Fig. 4. The sash 5 hinged on connecting hinges (not marked) becomes unscrewed after the screws have been removed.

Claims (4)

1. A double glazed window consisting of a carrier leaf and associated wing, fitted on the outside with a single or multiple glass pane and on its inner side with a single or multiple inner glass pane, characterized in that the inner glass pane (5) is by means of inserts (6) and independent groups of connecting elements, such as screws (7, 8), detachably connected to the supporting wing (1) and to the associated wing (2), so that one group of connecting elements (7) mounted freely in the supporting wing (1) is connected from one side to the mounting insert (6), while the other group of connecting elements (8) mounted loosely in the double window (2) of the double window is connected to the opposite side of one and the same mounting insert (6). 2. Double window according to item 1, marked8. releases it from the carrier wing 6 so that it can be opened for cleaning. The inner pane of glass 4 remains fixed to the support leaf 4 by means of inserts 4 and screws 4, also in FIG. 5. By screwing in the screws 4 and unscrewing the screws 8, the associated wing 5 is re-opened. However, in this case, the inner glass sheet 4 is fixed by means of clamping inserts 4 and screws 4 to the composite wing 6, see also FIG. 6. Thus, by independently releasing the screws 7 and 8, all surfaces of the glass sheets are occasionally cleaned. In the exemplary embodiment according to FIG. 3, a triple glazed window is formed, the double leaf of which again consists of the carrier leaf 1 and the associated leaf. According to the example of FIG. 1, the outer glass panes 6 and 6 and the inner glass panes 6 remain. A different way of fastening the insert 5 by means of screws 7 and 8 is evident from FIG. 3. This fastening method removes the connecting elements, i.e. screws 8 and 8 from the visible parts of the carrier wing 1 and the associated wing 6 and is suitable for strength reasons, e.g. the supporting wings 1 and the associated wings 6 are metal. In the case of metal wings of the carrier wing 4 and the associated wing 2, the fastening insert 6 made of a suitable plastic material creates a break in the thermal bridge and thus reduces the heat transfer coefficient. The fastening insert 6 may be local or may be in the form of a partial or complete frame with the cross-section of FIG. 3 around part or all of the perimeter of the inner pane of glass. According to the embodiment of Figs. 7 and 8, which show another improved alternative in two mutually perpendicular cross-sections, the support leaf 8 and the associated leaf 8 and the glass panes 4 and 6 remain identical to the preceding examples. The clamping insert 6 is divided into two identical parts 6a and 6b. By tightening the screws 8 or screws 8, the clamping insert parts 6a and 6b are pulled together and thus the fixing of the inner glass sheet 6 over the microporous rubber profile 60 is improved. The illustrated construction example also utilizes the plastic inserts 11 commonly used in the connectors of existing double windows, as shown in Figures 7 and 8. INVENTION, characterized in that the heads of the two groups of connecting elements (7, 8) are situated from the outside, the supporting wing (1) and the associated wing (2). Double windows according to Claims 1 and 2, characterized in that the fixing insert (6) is divided in a plane parallel to the face of the inner glass pane (5) and consists of two or more parts (6a, 6b) which are mutually connected by connecting elements / 7, 8 / intended to attach the insert (6) to the wings (1, 2). Double window according to Claims 1, 2 and 3, characterized in that the carrier leaf (1) and the composite wing (2) are provided with recesses (9) having an internal shape identical to the outer shape of the fixing inserts (6), the inserts (1). 6 / engage recesses in both wings, carrier wing (1) and composite wing (2).
