Description

TECHNICAL AREA

The present invention relates to an arrangement for Opening window.

When designing a facade on its outside completely or partially has glass surfaces are in generally consider the following points. On the one hand, the facade must have thermal and acoustic insulation provide. Furthermore, sufficient Ventilation options are created so that Windows are usually provided in the facade can be opened. This ventilation option should ideally also be given at night and it is also at open windows ensure that at least at ordinary, so not excessively heavy rain a certain Protection against the ingress of rainwater exists. About that In addition, a good one is possible even when the window is open To ensure sound insulation. Finally is through to take appropriate measures for sun protection, the should also be designed such that it is as good as possible is protected against damage caused by Environmental influences occur. These requirements apply especially for windows and window facades to be used for example in high-rise buildings.

STATE OF THE ART

Taking these aspects into account are disseminated Double facades are used, in front of a conventional, thermally insulated inner facade with opening windows a second glass skin is arranged, which i.a. is stationary. The space between the facade and the one in front Second glazing is arranged over the vertical Directed and / or ventilated through the openings provided and can also provide a shading system become. This is advantageously weatherproof, and by a double facade designed in this way both excellent thermal insulation and one natural ventilation even in rain and during the night, as well as good sound insulation achieved by the upstream, second glass skin even with the window open provides noise protection. The main disadvantages of Double facades are the high investment costs as well as that high dead weight in terms of the double facade load-bearing building lead to considerable structural problems can. There are also problems with increased Longitudinal sound line on. After all, training leads a double facade to special fire protection problems because between the surface of the double facade and the A chimney effect can occur on the outside of the building.

In the technology, window facades are also with Composite windows widely used, the composite window are openable and between the usually two Glass surfaces of the composite window one in this way may have protected sun protection. By such composite windows can be a good heat and Soundproofing can be achieved at investment costs that are lower than with a double facade. The disadvantages Such composite windows are, however, that the Investment costs are significantly lower than for one Double facade, but still higher than usual Window facades that they offer no noise protection, and that moreover, with the window open, no protection against Driving rain is given.

PRESENTATION OF THE INVENTION

In view of these disadvantages, that of the prior art known measures on windows and facades it is the task of the present invention, an openable To create window arrangement, even with the window open with good thermal insulation and adequate sound insulation provides good ventilation behavior.

The solution to this problem is provided by Opening window arrangement according to claim 1 achieved.

The invention is based on the idea of two of each other use spaced, completely separate window sashes, which are highly insulating due to the spacing and are highly sound absorbing and with a simple construction one full and inexpensive replacement for one Provide ventilable double facade.

Accordingly, the invention is based on Hinged window arrangement with at least one window frame, a first window sash, which is parallel to the window frame in a first opening direction is deployable, a second Window sash parallel to the window frame in one second exhibition direction is deployable, and one Drive unit with which the first and second window sash are exhibited, the first exhibition direction of the second direction is opposite. Through the opening window arrangement according to the invention are the first and the second casement can be opened, so that the Ventilation behavior is significantly improved. Because of the circumferential window gap achieved by the exhibition ideal ventilation behavior is achieved because both the emerging exhaust air as well as the incoming fresh air usually the same window gap is available. The first and second window sash are parallel to the Extendable window frame so that when open Window sashes against rain and noise a labyrinth and consequently adequate protection against driving rain and incoming noise is provided. Under one Parallel exhibition in the sense of the present invention movement of the window sash relative to the window frame understood or stick, with the wing preferred is always parallel to the floor, but also inclined Position of the wing relative to the stick is conceivable (wedge shape). According to the invention, the opening direction is the first Window wing of the opening direction of the second Window wing facing the opposite. In general, will one of the window sashes (the outer one) to the outside of the building the other window sash (the inner one) to the Open the inside of the building. Accordingly, according to the invention better use of space on the inside of the building is possible, than this with the same ventilation conditions with rotating windows or conventional double facades would be possible. Likewise is by the invention due to the window frame in a double facade prevents chimney effect. in the general are the closed casement lie completely against the window frame. By the Parallel structure of the opening window arrangement and the related leave the corresponding opening movement of the window sash through only partially flared window sashes ventilation conditions corresponding to current requirements create. The first window sash and the Open the second window sash to different degrees. Furthermore, the arrangement according to the invention in Install fixed openings of facades that essentially how openings are made for conventional windows, so that the structural requirements for the building are more easily met can be. It will be compared to the double facade achieved significant cost savings.

To protect the opening window arrangement against Weather conditions and noise continue to improve according to the invention advantageously between the window frame and at least one of the window sashes has a side one Cover provided. The assembly of this side cover can partially on the one or the sash on the one hand the window frame, on the other hand, or both of these Components are made. When closed the Window sashes act as parts of the cover for sealing together with the opposite components, so that the Arrangement in the closed state liquid and largely gas-tight and visible and open when open is protected from the weather. They are in the open state Opening properties of the cover by the degree of opening of the window sash can be influenced. In general extend the covers described for example tine-like, both on the frame side in the direction of the window, as well as on the window side in the direction of the frame. The good ones Ventilation properties of the invention The opening window arrangement is preserved, the penetration of Driving rain and the occurrence of noises are made more difficult. A spacious room between the window sashes supports the effect of the side covers.

To the load on the components supporting the window sash to keep it low or to enable these components can be constructed to save space, is according to one advantageous development of the exhibition path of the first Window sash and the opening path of the second window sash limited. The limitation also prevents the windows, especially in high-rise buildings, so far can be opened that bulky objects by the resulting gap can be thrown out.

A symmetrical configuration reduces the Number of the opening window arrangement according to the invention required components and enables a modular Structure, i.e. the one used to attach the first Window sash required components also for the Attachment of the second window sash can be used if so desired. For this, the amount of The opening path of the first window wing is the same as that of the second Casement.

The construction of the opening window arrangement according to the invention the wall thickness of the Exterior facade used, so that for example one of the Window sash flush when closed The outside of the facade, the other window sash in the closed Condition is flush with the inside of the facade. This spacing of the two window sashes when closed it, between the first and second casement Arrange components. It is advantageously there according to the invention, the drive unit arranged so that necessary construction measures when installing the invention Hinged window arrangement kept as low as possible become. This is especially for retrofitting one existing building facade of interest. The drive unit can contain a remote controlled electric motor.

The necessary to open and close the window sash Power is transmitted to them by actuating means that according to the invention advantageously between the first and the second window sash are arranged. Such Actuating means are, for example, by lever Slide rods, scissors, cables, and / or springs are formed, these components used individually or in combination can be.

The drive unit, or in particular the actuating means as part of the drive unit, can also be in one preferred embodiment of the invention the limitation of Opening paths of the first and second window sash cause so that on additional components, such as attacks or the like can be dispensed with, which otherwise should be set. Furthermore, the limitation is before protected against unwanted manipulation.

Because it takes the effort to design and manufacture the necessary for opening and closing the window sash Components considerably simplified when using the Hinged window arrangement of the first window sash and the second casement at the same time in their respective Exhibition directions. That way advantageously a symmetrical exhibition process of the two Wing over, for example, a single and central arranged drive unit or actuation allows.

The window frame preferably has a central profile part and Side profile parts on each other by thermal insulation bars can be separated. This thermal separation can from the central profile part to the side of the first Casement as well as to the side of the second casement be provided. When using such a frame is ideally the drive unit in the central profile part integrated.

The opening window arrangement according to the present invention according to a special embodiment, also includes a Sun protection. This sun protection can be special advantageously protected from the weather either between the both window sashes or in or on the outer Window sash be attached. When attaching the Have sun protection in or on the outer window sash Measurements show that incident sunlight without excessive darkening is particularly effectively shielded can be.

When installed between the two casements, the is Sun protection preferably attached to the window frame, whereby it is particularly protected from the wind. When attaching the He has a sun protection in or on the outer window sash better sun protection effect and is when open Flared window arrangement better. As sun protection can, for example, blinds, fabric or film surfaces be used.

The second window sash 20 is corresponding to the Facing the inside of the building. 1 are both Window sash shown in the closed state.

The first window sash 10 includes a frame part 11, in which a window 16 is added. The frame part 11 is in the closed state via seals 14, 15 a side profile part 32 of the window frame 30.

The second window sash 20 includes a room side Frame part 21 and a frame-side frame part 22. Die two frame parts 21, 22 are via thermal insulation webs 23 mechanically connected and thermally from each other Cut. In the frame parts 21, 22 is a window pane 26 included in this embodiment in Double glazing is designed. The second casement 20 lies in the closed state over a first seal 24 on a further side profile part 32 of the window frame 30, and via a second seal 25 on a central profile part 31 of the window frame 30.

The window frame 30 comprises in the illustrated exemplary embodiment three profile parts, namely one Central profile part 31 and two side profile parts 32. Also these profile parts are mechanical via thermal insulation webs 33 interconnected and thermally separated. On in this way form the central profile part 31 on the one hand, the Side profile parts 32 on the other hand and the arrangement of these Profile parts 31, 32 to one another via the thermal insulation webs 33 different cavities that are beneficial for thermal insulation are. The thermal insulation webs 33 are made of one material low thermal conductivity but sufficient strength educated. On the one hand, they prevent a thermal bridge occurs between the profile parts 31, 32, on the other hand they give the window frame sufficient strength. The thermal insulation webs 23 of the second window sash 20 fulfill this double function.

The drive unit 40 is arranged centrally in the central profile part 31. In the described embodiment, it essentially consists of an electric motor 42, which acts on an actuating rod 44 via a gear (not shown). The actuating rod is received in a form-fitting manner in a suitably designed cavity of the central profile part 31. A cable 46 is attached to it, which acts via deflections 48 on both the first window sash 10 and the second window sash 20. The drive unit 40 of this exemplary embodiment furthermore comprises a plurality of springs, which emerge in particular from the horizontal section of FIG. 2 and are explained further below in this connection. The drive unit 40 causes the first window sash 10 in the first opening direction A ₁ , and the second window sash 20 in the second opening direction A ₂ .
