Abstract

The invention relates to a frame for windows made of plastic material, having frame profiles designed as hollow profiles. Said frame profiles are connected to one another in the corner regions in a mechanical manner or by welding. In the resulting frames there are introduced at least two glass panes which enclose an interspace with an air cushion. On each frame profile there are integrally formed inwardly and outwardly angled pane-receiving webs which, when the frame is in its interconnected state, form a peripheral, narrow bearing surface for the pane borders. The pane borders themselves are connected to said bearing surface in a manner sealed with respect to diffusion. In order to compensate pressure fluctuations occurring between the panes, pressure-compensating elements are arranged in or on the profile walls directed towards the interspace.

Description

The present invention is directed to a window or door frame made of plastic with hollow frame profiles, which at the corners are sealed together with one another in the presence of. fitted with at least two window panes.

In today's window technology, similar types of .frames are assembled with known insulating window panes. Such insulating glass panes are, as a rule, single glazing with an organic adhesive bonded to the edge of the glass. At the same time, a spacer holder, usually an aluminum frame, is installed in the window panes. The void remaining above this distance of the bracket to the edge of the window panes is filled

-Sealing material that maintains its elasticity for a long time. In addition to this ¹ long-lasting elastic sealing material, thermoplastic sealing materials may be used.

Alternatively, the window panes are filled with a high-activity adsorbent (dry material) and a perforated spacer bracket, covered with a long-lasting plastic sealant, such as butyl, without leaving any gaps on the outer surface. This internal gasket is used primarily to seal the gap between the window glass and the water vapor that penetrates it. The advantage here is that butyl has a very low rate of water vapor diffusion. In addition to this water vapor seal, the void above the spacer bracket-frame to the glass edge is again filled with long-lasting elastic sealant for external sealing.

This additional sealing of the edge of the glass particularly helps to seal the two glass panes so that they can withstand the mechanical and thermal stresses. In addition, it creates an airtight or gas-tight window

· Intermediate window barrier, which prevents moisture from penetrating into the window glass cavity.

The described insulating glass windows are inserted into plastic frame profiles, which are firmly in the corners. to connect with one another. According to German patent '2840656, this connection of the corners of the frame profiles can be performed, for example, by mechanical screws. Any frame profiles can be joined by. German Application 7419472 for Angle Joint Welding ^ These connection methods are well known and the cited publications are used only as an example of known technology.

Insulating glass panes are inserted into. of the frame thus produced. receiving surface and. glass

-.the flange-frame is held firmly in place. An example of this glass-holding frame is German Application 8225258.0. Insulating windows. Are firmly fixed 'in this way. the window frame created by it, is exposed to strong environmental loads such as air, temperature, sunlight, etc. Can be reached., Up to + 80 ° C and higher. These temperature loads have a decisive influence on the construction of the window panes. It should be borne in mind that the gas between the window panes changes its pressure as the temperature changes, which may cause the panes to become flat or convex. Along the thermal pressure change, a change in external conditions - atmospheric pressure, wind power, etc. · can contribute išorinių'sąlygų pressure and an unfavorable case, it can sustiprėtįVisos this adversely affects the possibility of _not have to 'be made known · insulating window panes, and particularly the edges of joints. This has led to costly measures such as thicker window shades,.

for better pressure acceptance and distribution, and for edge management. and sealed in window glass joints, etc. , i.e.

It is an object of the present invention to provide glazing for window panes: to replace insulating glass panes which have edge joints costly due to the state of the art in many panes and to provide a glazing technology that can be used even without prior preparation of the glazing; Another task is the creation of a multiple-glazed window frame with pressure equalization. For this purpose, it is proposed according to the invention to form angled paths on the inner and outer sides of the frame profile, which in the frame joint form a circular, narrow support surface for the edges of the glass which are sufficiently tightly connected to this support surface , 'reciprocating -the intermediate cavity', -the pressure equalization elements arranged to compensate for pressure fluctuations between individual window panes.

According to the present invention, the frame, in addition to its direct window-frame function, is additionally a holder for the distance between the two window panes. The frame construction is so arranged that the sash profiles in both. one window glass can be installed on the sides. The glass fastening paths are angular in shape and form a closed support surface for the window glass to enter into the surrounding frame.

It is useful 'that at least one part of the profile wall is made as a flexible wall', which is a pressure equalizing element in the coextrusion path.

f.

- it is particularly expedient to have at least one of the flexible joints in the area of connection of the glass fastening tracks to the frame profile. · ^; 7 / γγΥ

As a further development of the invention, at least one flexible enclosure wall hollow chamber having an internal cavity through / frame profile wall breakage is provided with a pressure equalization element between the window panes in contact with the ambient atmosphere. In addition, it seems appropriate that the glass fastening paths are joined by a short crotch with a frame profile. In this way, it is possible to insert a D-shaped holding leg into the free space between the outer surface of the frame profile ¹ and the surface of the glazing path, and the opposite leg of this profile extends to the outside of the window glass.

Finally, for a window glazing edge with a glazing track, it is advantageous for the glazing edges to have a profiled backing plane for the glazing edges and to have a long-lasting elastic sealant inserted between that glazing plane and the glazing edge.

The advantages of the construction according to the present invention include in particular:. that-. a window frame can be manufactured at a low cost at any window manufacturing company. ' At the same time, expensive production lines' required for 'regular' insulating glass can be dropped. The window can be assembled faster, using traditional methods. There is also no need to put sealing gaskets on the glazing - and to cut the glass, which is labor intensive.

In accordance with the present invention, in the method of frame manufacture, multi-skylight windows (composite windows) are replaced by cost-effective insulating glass. lancfo glasses. Simple compound windows because of the need to use a separate sash for each window glass is a frame manufacturing method of the invention.

In terms of integrated pressure equalization in the manufacture of the frame according to the invention, glass. edge. the coupling has a theoretical lifetime due to lower pressure and suction conditions compared to known fabricated designs.

In addition, the equalization of pressure between the window panes also reduces or prevents the mirror-distorted reflections which, in the present state of the art, sometimes appear due to the strong deformation of the panes.

'

Increased distance between window panes at low window thickness allows good sound and heat reduction value. This significantly reduces the cost of window glass and the weight of the glass itself.

Due to the high vapor diffusion resistance of polyvinyl chloride (PVC-profiles) and the fact that the angles of the profile are obliquely welded to the air in the joining area, it is possible to use the frame as a distance bracket for joining glass. If necessary, suitable diffusion resistance coefficients may be increased accordingly by suitable means such as varnishing, foil sealing, spraying and the like. The pressure between the inner cavity of the window glass joint and the ambient atmosphere is equalized thanks to the pressure equalizer element, which is fitted in the profile. in or mounted on a wall. If this pressure equalizing element is located, for example, in the region of the window fastening path of the inside window, then the interior glass can, in this design, move with this elastic connection, causing the air gap between the two windows to increase or decrease depending on the direction of force.

The profile holding the glass helps to protect the window panes installed in their place on the angled windows. This refers to the profile of the U-formi © s', which is cut for diagonal. And

mounted around the edge of the glass so that one leg of the Uprofile covers the edge of the glass, while the other leg of the U 'profile engages the inner surface of the glass fastening path. In this way, the windows are mechanically secured by gluing on the long-term elastic sealing device in the support plane of the glass fastening path. Under pressure from the inside of the window glass, the profile holding the glass in addition prevents the window glass from falling off the glass fastening path.

Frame profile with its rigid frame areas and variable pressure equalization - the element in the coextrusion path is made as one unit.
