case and at least one. it has a hinged wing with a glass panel, the hood consisting of two hinges, the hinged wing being one of the hinges facing the outer space and the other facing the inner space, one of the hinged faces facing the outer space and the other facing the inner space , the facing sides of the half-casing and the facing sides of the half-casing are provided with slots and there is a gap between them, and the casing and the opening flap have fittings for securing the window structure when closed.

For buildings, the early introduction of light into the interior was an important requirement. For this purpose, openings were formed in the walls of the buildings, through which light and air could flow freely into the premises. The next task was to ensure that only light could penetrate the opening, while the air could be blocked.

In the early days, materials of animal origin, e.g. the bladder was used for this purpose. A great step forward was the use of natural minerals and the invention of glass. From now on, we can talk about the formation of windows in the modern sense.

For a long time, the windows were single-layered and usually had small sections. They were close to their purpose, but due to their high cost, their spread was limited.

- 3 Since the Industrial Revolution, low-cost panel glass has made it possible to make multi-layered windows at affordable prices. Two-leaf window structures have been formed. Previously, they were made by hand-crafted glass panels with wooden frames in custom sizes. Later, mass use necessitated serial production of windows. In the XX. In the 20th century windows were made of metal, plastic or a combination of these.

The strength, shape and dimensional stability of the materials used in the production of window structures are extremely important. Wooden constructions are perfectly suitable for thermal conditions but are prone to warping. Particular problems arise with surface protection, eg. against fungus. A further disadvantage is that, for large surfaces, the thickness of the frame structure must be strongly increased. As a result, the weight of the structure also increases, which is a disadvantage for users.

Plastics are resistant to corrosion and pests. Their surfaces are maintenance-free. They have the disadvantage that they have a low load-bearing capacity and that plastics of adequate strength are expensive and thus uncompetitive.

Metal windows, which are also favorable for mass production, are heavy-duty, do not warp, have good weather resistance and can be easily protected. Their disadvantage is that, due to their thermal conductivity, they do not meet the insulation requirements.

The next step in the development is the so-called thermal bridge. sandwich structures are made by joining different materials together. Such is the H-type doors and windows family of the Hungarian Metal Workers Company. Here, two aluminum profiles are joined by snaps on a flexible PVC profile. The advantage is high productivity, the disadvantage is that the PVC profile creates only a small amount of aluminum profiles.

Windows of MATUSCHEK and BRÖCKELMANN in Germany are more suitable for strength and aesthetic requirements. Both companies glue together different window profiles. The advantage of gluing is that it can work together and different materials, eg also suitable for joining aluminum wood. The disadvantage is that it requires the use of special purpose machines. The above knowledge is discussed by József KöSZő: Windows / Technical Publisher, 1980/ c. work.

A steel framed window structure is described in German Patent Publication No. 31 05 512. Both the casing and the hinged flap are made of rolled sheet metal and are constructed with stone insulating spacers in two halves.

The window structure with state-of-the-art sandwich windows cannot compete as it only contains two single-layer glass. The assembly of tols, sashes and glasses requires a great deal of cushioning, sealing, joint filling and covering, as well as special screws.

The sandwich structure is a window structure according to EP 0 103 272, in which plastic strips are inserted between the aluminum profiles, foamed between them, and finally the structural cross-section is stamped onto the plastic strip.

Foamed joints are indeed suitable for creating a thermal bridge-free window structure under certain climatic conditions, but are uneconomical for milder climates, ie for smaller requirements.

A similar solution is provided in Hungarian Patent Application No. 186335 with the exception that a grooved rib insulating bar is inserted into the connecting groove of the profiled metal bars.

The window, which can be produced with the help of an insulating rod, is heat-bridged only in a given climate environment. However, the disadvantage of this structure, unlike the previous one, is that it is suitable for a temperature corresponding to the Central European climate, but it does not meet stricter conditions. A further disadvantage is that the metal profile is mechanically secured to the insulating rod and, due to the widening groove of the metal profile, the transmission of force between the two semi-profiles forming the enclosure is uncertain, since the insulating rod may be displaced.

The latter error is corrected by the heat-sealed metal frame for doors and windows, known from Hungarian Patent Application No. 183807, of aluminum semi-profiles. The aluminum semi-profiles are provided with grooves, the grooves with bumps. Half plastic profiles are inserted between the half profiles and also have hook hooks. The insertion is thus securely connected to the half-profiles and, within certain limits, provides a secure connection between the half-profiles.

The disadvantage, however, is that it satisfies the requirement of thermal bridging only in a narrow area and does not provide a way to make it suitable for wider needs.

The common feature of all the solutions described is that they can only be reliably applied in a specific climate environment. In other circumstances, a completely different solution must be applied. It follows, however, that many components of a variety of structures have to be manufactured, transported and mainly stored. This circumstance renders heat-free window structures uneconomical.

It is an object of the present invention to provide metal windows such that

Multi-directional requirements can be met simultaneously and economically, meaning that a single window structure can be used for multiple, even extreme climatic conditions and / or different building types.

Namely, if we can tailor structural solutions closely to the requirements, we can apply the necessary and sufficient structural solution to each situation, that is, the most economical. The challenge was to make the window structure as small as possible with aesthetically pleasing and thermal conditions, thus reducing storage costs, which increase the cost of installing the structure.

It is also intended that certain elements of the structure work together safely, so that a reliable force connection is established. No complicated parts, no special machinery, no maintenance needed.

The idea of the invention is based on the discovery that if both the casing and the wings are disassembled into separate parts and subsequently assembled, they may always be of the design most suited to their function. It is further recognized that the connection between the outer and inner structural members can also be used to create the thermally required distance. It is also recognized that the use of the same components and the same coupling • • • ·

- In case of 8 different types of structures can be produced, thus adapting the way of interconnection. To do this, the shape of the components must be properly selected.

According to an object of the present invention, a heat-sealed window structure according to the invention having a casing mounted on the wall separating the interior of the building from the outer space and an opening wing comprising at least one glass pane is formed by two half casings and a half casing. one facing the outer space and the other facing the inner space, likewise one of the half-wings facing the outer space and the other facing the inner space, the facing sides of the half-caps being grooved and spaced between the and on the swing wing, there are fittings for securing the window structure in the closed position - formed by spacers adapted to the environmental climate in the mid-frame and between the mid-wings, which also allow the mid-frame and the half-wings to work together; They are secured in the cavities formed in the hemispheres and the half-wings, when the window structure is closed, the outer half-wings lie on the outer half and the inner half-wings lie on the inner half, the fastening fittings or the outer half on the wings and the outer side. placed on a half case, or preferably on the inner half-wing and the inner half-shell, and the inner half-wing and / or the inner half-case being optionally the inner side

--- It is provided with an insert from above, and the height of the groove exceeds both the cross-sectional height of the half-casings and the cross-sectional height of the half-wings.

A further feature of the window structure according to the invention may be that the spacer is made of plastic, is secured by snaps into the grooves of the half-casings and / or half-wings, and that it fills up the spacer at most. The spacer is also secured to the gap between the half-cases and / or half-wings by gluing.

In another embodiment, the spacer is a post-solidifying spacer inserted into the spacer and is at least partially shaped in the form of grooves in the half casings and / or half wings.

The insert is clamped in a trough on the inner half-wing and / or inner half-cap. The insert is made of a heat-insulating material, e.g. is made of wood, plastic or a combination of wood and plastic.

It may also be appreciated that a seal, preferably a swinging seal, is provided between the abutment faces of the outer half-wing and the outer half-shell, and also a seal, preferably a compressible seal, between the abutment surfaces of the inner half-wing and the inner half-shell.

The thermal bridge window structure of the present invention has several advantages over known solutions. Particularly noteworthy is the fact that using the same structural elements different needs can be met without the need for additional material, and thus economically. The separation of the structure does not require the addition of additional material. Due to the shape of the structural elements, a single set of element types and various connection solutions can optimally meet emerging needs. The collaboration between the elements is also tailored to the needs. The production is fully automated and thus it is possible to make windows satisfying every possible need by using robots. A small number of battery types facilitates storage, low inventory, and low cost storage. The appearance of the window is aesthetically pleasing and there is no unpleasant cold.

In Fig. 1, the same spacer 4 is snapped into the groove 3 of the inner half case lb and simultaneously into the groove 3 of the outer half case 1a. The gap 14 between the half bags 1 is only partially filled by the spacer 4. Collaboration of the resulting structure is effected by friction between the spacer 4 and the inner half-shell la of the la and the inner half-shell lb. It can be advantageously used in the case of a less demanding structure.

In Fig. 2, a curing spacer 4a is provided in the groove 3 formed between the outer half-shell 1a and the inner half-shell 1b. The post-solidifying spacer 4a completely fills the grooves 3 of height h and even the bulk of the gap 14 between the half-shells 1. It is possible to increase or decrease the spacing 14 between the outer half sheath la and the inner half shelf lb as needed. The height of the post-solidifying spacer 4a may also be increased up to the height h of the half-case 1.

In Fig. 3, a spacer 4 is inserted in the groove 3 between the outer half-shell 1a and the inner half-shell 1b, and for better cooperation, the adhesive 6 is placed in the portion of the groove 3 facing the flap not shown here. This makes it possible for the half-shell 1 to have a cross-sectional height h that exceeds the height h of the grooves 3, so that the portion 14 of the gap 14 extends beyond the groove 3.

- 12 _w adhesive anyag._

Figure 4 differs from that described above in that between the portions 14 of the spacing 14 left open by the spacer 4, the adhesive 6 fills the flap and the opposite side thereof. In this way, the cooperation between the structural elements is further enhanced.

Figure 5 illustrates a possible variation of the aluminum window structure. On the outer side of the auxiliary wing 13a is a water conductor 9, an outer glass seal 11 and a glazing 12 applied in the last operation. The compressible seal 8 and the glass clamp 5 are fastened to the inner half-wing 13b, which forces the double-glazed panel 7 to seal the outer glass 11. The outer half-wing 13a and the inner half-wing 13b are secured to each other by the post-solidifying spacer 4a. The swing seal 10 is disposed on the outer casing half la. The outer half-case 1a and the inner half-case 1b are interconnected by the self-stabilizing spacer 4a. The height of the self-stabilizing spacer 4a is less than but not greater than the height of the hh at the opening flap at the cross-sectional height hs of the half-wing and at the cross-sectional height h of the half-shell. By varying the width of the spacing 14, the distance between the half-shells 1 and / or the half-wings 13 can be varied.

In Figure 6, the inner side of the window is provided with inserts 2. The insert 2 is formed by the inner half case lb and the inner portion 13b

-— · along side half-wings. Press the glass plate 7 with the glass clamping insert 5 against the glass seal 11 on the outside. The spacer 4 on the outer side la and the inner half on the inner side 1b are joined by the spacer 4 complementing the adhesive 6. The spacer 4 protrudes into the grooves 3 but does not completely fill the spacer 14, which allows the adhesive 6 to be positioned. With adhesive 6, contact forces can be increased, which is usually required for tall buildings (over 30 m).

The heat-sealed window structure of the present invention can be adapted to the particular climate and type of building, both industrial and residential. It is also possible to produce windows with increased thermal insulation value using conventional technology.
