DD202196A5 - COMPOSITE WINDOW WITH LABYRINTH SEAL BETWEEN FLOOR FRAME AND FRAMES - Google Patents

Abstract

The invention seeks to provide a simple and cost-effectively producible composite window which has good heat and sound deadening values and in which no formation of condensation occurs on the inside of the outermost pane. According to the invention, this is achieved in that, in the case of a composite window, the attachment frame is struck on the outside of the wing frame. Wing frames and attachment frames are glazed separately. Between both is a labyrinth seal, which is designed so that it allows between the window outer side on the one hand and the space between the two glass panes on the other hand, a vapor pressure equalization. As a result, on the one hand, condensation on the glass panes is prevented, but on the other hand, sufficient heat and sound insulation of the composite window is ensured.

Composite window with labyrinth seal between casement and header frame

the invention

The invention relates to a composite window comprising a frame and a hinged to this wing frame and an attached to the latter attachment frame, with casement and front frame are glazed separately and is a seal between them.

Characteristic of the known technical solutions

As a result of the energy shortage, the energy saving, especially in the heating of buildings, has become an important task. In this regard, windows are still vulnerabilities that can be expected to result in significant energy savings by improving

As for cost reasons not everywhere windows can be replaced by new, heat-insulating, less expensive, wings have become known, which - in conjunction with an improved seal the Flügelfalzee - can be retrofitted with old windows and promise an improvement in the thermal insulation value »These wings are inside simply glazed casings bolted on · Between the casement and the attachment frame, which is also simply glazed, there is usually a circumferential seal. In this attachment frame, the problem of condensation on the interior

side of the outer pane. This problem can not be solved by a ventilation of the attachment frame, unless the venting allowed such a strong warm air flow on the inside of the window of the sash that its temperature is raised to a value above the dew point. In. Such a rear ventilation but the attachment frame would be virtually without effect.

There are also known so-called wood-aluminum windows, in which on the outside of both the wooden window frame and the wooden sash an aluminum profile is screwed, which should protect the wood parts from the influence of weather. These windows have an insulating glazing between an internal glazing bead and the aluminum profile. The aluminum profile in conjunction with a glazing, this window is very expensive and is also subject to other problems. Thus, a special type of fastening of the aluminum profiles on the respective wooden frame allows for a mutual displacement required as a result of the different coefficients of expansion. This inevitably leads to certain leaks between the glazing and the aluminum profile, which allows water to penetrate. Although the aluminum profiles provide for a water drainage, it can not be completely prevented that moisture gets into the sealing area of the insulating glazing and damages its seal in the long term, as a result of which the insulating glazing can become blind.

Essence of the invention

The object of the invention is to provide a composite window, comprising a frame, a hinged to this wing frame and attached to the latter attachment frame, with sash and header frames are glazed separately and between both a seal is to create, which has good heat and sound insulation values and in which no condensation occurs on the inside of the outermost disk ·

This object is achieved according to the invention in that the attachment frame is posted on the outside of the sash and that there is a labyrinth seal between sash and attachment frame.

The labyrinth seal allows a limited flow of outside air through the space between the header frame and the sash · This provides a vapor pressure equalization which prevents condensation on the inner side of the glass of the header frame · As the access of outside air into the area between the However, both floors by the labyrinth seal is limited, but can still achieve satisfactory values for both the thermal insulation and the sound insulation · In addition, it is of course also possible, if necessary, to carry out the glazing of the sash as insulating glazing, due

the protection provided by the glazing of the front frame is not directly exposed to the weather and therefore has a long service life.

Advantageously, the frame and the sash made of wood, while the header frame is formed of an aluminum profile.

The attachment frame is preferably made of aluminum! but there are also other, preferably weather-resistant materials, for example, plastic into consideration. It is particularly advantageous, according to the invention, when the dimensions of the attachment frame are chosen so that it covers the wing frame substantially over the entire surface, so that the preferably made of wood casement is protected from the weather ο To protect the wooden frame can be a corresponding intent Be provided frame.

Both the thermal and the acoustic insulation will be better, the greater the distance between the glazing of the attachment frame and that of the sash frame. For this reason, it is advantageously low, contrary to the usual, the glazing of the sash as close as possible to the inside. lay. The glazing bead of the sash frame can then be expediently provided on the outside of the glass.

For the labyrinth seal various possibilities are conceivable. A simple possibility according to the invention consists in the fact that the labyrinth seal comprises a plurality of elastic sealing strips, which on different unifing lines, themselves

This labyrinth seal may advantageously comprise an inner and an outer pair of substantially U-shaped sealing strips, of which the sealing strips each have a pair with the open sides the U are opposite and both pairs are offset from each other by 90 °.

Depending on the type of weather strip, it will be necessary to decide whether it will be attached partly to the sash frame and partly to the sill frame or all but one of these frames. It may be advantageous to attach all the weather strips to the wooden sash, into which light hats can be milled to accommodate such strips,

The leaf frame 2 and sash 4 located circumferential seal is not shown here »The sash 4 is glazed in the example reproduced case with a single-pane of glass 6 ', which is taken between an upstanding edge 4a of the sash 4 and a glass bar 8. The glass sheet 6 is located approximately in the rear third of the depth of the sash profile. At the lower transverse side is placed on the frame 2, an aluminum profile 10 of conventional design.

On the outside of the sash frame 4 a Yorsataflügel 12 is pivotally hinged to this about a vertical axis While frame 2, sash 4 and glazing bar 8 are preferably made of wood, an aluminum profile is preferred for the attachment frame 12. As already mentioned, but also comes - among other things, a steel-reinforced if necessary - plastic profile for the attachment frame 12 into consideration. The pre-etching frame 12 is glazed with a single glass pane 14, which may be thinner than the glass pane 6.
