Description

The invention relates to a glazed component, in particular a window, with a reversible glass pane arrangement, consisting of a rectangular fixed web and a fixed frame around an axis parallel to one of the edges, in particular the vertical rectangular center line, from a first, fixable, sealed position by 180 ° in a second, fixable, sealed position pivotable frame, in which a translucent pane arrangement is inserted, so that the pane arrangement has one or the other pane surface facing outwards (or inwards), the pane arrangement of the enclosed frame being anisotropic Glass pane comprises, the solar energy in one direction more than in the other direction, and with actuators for fixing and / or sealing in one position by moving the movable frame in the direction of the pivot axis, in which a fixable position between d s perpendicular to the swivel axis lying frame sides of the two frames, a tongue and groove connection is created, and the actuating device comprises a thrust drive arranged at one end of the pivot axis, and wherein ventilation gaps remain between the vertical bars of the fixed or movable frame, which are attached to the fixed frame by means of sealing devices and ventilation flaps pivotable away from the movable frame or a second movable frame attached to the fixed frame can be closed.

Such a glazed component, which, however, only has the ventilation flaps mentioned, is already known from the "bauplan" magazine, International Technical Economic Journal, published on July 14, 1986, pages 206, 207, and from DE-U-8602453. With one fixable position, solar heat can be obtained in winter (and room heat retained), while in the other fixable position, a large part of the heat radiation that otherwise penetrates through the window can be prevented in summer. This window has advantages over the standard double-glazed "normal windows" because this "normal window" still represents a "weak point" in the thermal insulation of the building with regard to its thermal transmittance values. The "heat gain" that is often not desired in the warm season is offset by heat loss in this normal window during the heating season. Although the development of thermal insulation glazing has made it possible to significantly reduce heat losses through the glazing of windows, "summer thermal insulation" (unless roller shutters, blinds or curtains are used as aids, but which limit the amount of daylight) remains a problem.

By the described in the mentioned utility model Rotatable reversible wing element in the summer position is reduced by means of an outward-reflecting layer of triple glazing, which is undesirable solar heat energy, while with a 180 ° turn of the window sash for the winter position it is achieved that the radiation of heat from the room is reduced via the then Interior-facing reflective layer takes place, whereby the thermal insulation of the window is almost as good as that of the wall, which both counteracts the winter heat losses and summer heat protection is achieved at high outside temperatures. This design, which comes from the applicant, enables the heating requirement to be reduced by up to 80%. As stated in the publication, the special glazing and the possibility of turning through 180 ° enable two functions to be carried out simultaneously:

In a winter position, thermal use means that the long-wave rays of the sun are converted from the glazing into heat. This heating takes place on the pane facing the room. From a light irradiation of almost 25 watts per m², a pane surface temperature of over 20 ° C is reached. In this state, the window is thermally neutral, i.e. that is, there are no more heat losses. If there is a higher level of radiation, the window acts as a radiator. The excess heat is available to the room, the output of the installed heating can be reduced. This turns the window, which was previously considered a poor physical component, into a radiator.

However, this ideal situation for winter is unfavorable in summer. Because of the pivotability into a summer position, however, it can be achieved that the heat is then intercepted from the outside on the first pane, with special devices that are not described in detail Reject heat for the most part. The basic thermal requirements of a high-pressure weather system support the convective heat relief of the outer pane, so that good summer heat protection is achieved.

The window described also has ventilation, which is adjustable on the one hand, and on the other hand allows caramel recovery. However, details of this are not explained.

From DE-A-2607937 a window element with two glazings arranged in corresponding frame parts is known, between which glazings there is a ventilable cavity. The two frame parts carrying the two glazings are connected to each other by means of threaded bolts adjustably connected and thereby adaptable to holding frames of different thicknesses, the holding frame in turn being pivotable in a fixed frame. To the cavity z. B. to make it accessible for cleaning purposes, the inner frame part can be folded away from the outer frame part by means of a sliding hinge. There are also horizontally arranged air passage openings, which are equipped with plug-in insect protection devices and with rainwater protection devices.

From DE-A-1 946 597 a continuous ventilation device is known in connection with a tiltable window sash, in which profiles made of plastic and anchored in the window frame allow an air flow path which prevents the ingress of impact rain when it is arranged horizontally. Individual parts can also be plugged into one another. However, there are no possibilities for attaching insect gauze, and the vertical arrangement is not provided and also does not provide protection against driving rain and no possibility of accommodating actuating devices.

From GB-A-2 083 203 a ventilation device for doors or windows is known which also consists of plastic and parts which can be plugged into one another and which secures against driving rain if it is arranged horizontally. It also includes insect gauze, but is for vertical installation Windows and the like are not suitable and also do not allow actuators to be accommodated in the interior of the profile.

The object of the invention is, in the case of a glazed component with a reversible, anisotropic glass pane arrangement, with a tongue and groove connection on one side and with a lifting bar which can be moved by a thrust actuator on an opposite side, and with ventilation flaps which can be pivoted away from ventilation openings on the remaining further sides - as from known in the prior art (DE-U- -86 02 453) - to improve the U-profiles for holding sealing lips and possibly insect gauze, which are also known there and are arranged in the ventilation openings, in such a way that they provide effective protection against driving rain, without losing the possibility of accommodating the actuating devices in the interior of the U-profile, which may be inaccessible from the outside.

In the prior art, as well as in the other publications mentioned, for the purpose of driving rain protection, ledges projecting into the interior of the U-profile are arranged, which make this accommodation more difficult.

The object is achieved by the characterizing features of claim 1, that is, in that the U-profile comprises a mushroom-shaped strip in profile, which forms a meandering path for fresh air and thereby a driving rain cover together with projections emanating from the U-profile.

Characterized in that according to claim 1, the U-profile comprises a mushroom-shaped strip in the profile, which forms a meandering path for fresh air together with projections starting from the U-profile and thereby forms an effective driving rain cover even with a vertical arrangement, there is also the possibility of securing of vertical ventilation gaps. Since, in addition, the inside of the U-profile remains free, the possibility is opened for possibly accommodating the actuating devices in the interior of the U-profile, which makes the actuating device inaccessible from the outside and thus safer.

Such accommodation is made even easier (claim 2) if the U-profile consists of two parts that can be plugged into one another. In addition, the arrangement of attachable parts enables the interchangeable arrangement of insect gauze (claim 3).

The invention is explained in more detail below on the basis of exemplary embodiments which are illustrated in the drawings.

In a schematic representation, in addition to a first movable frame which carries the reversible glass pane arrangement, a further movable frame articulated by means of a displaceable pivot bearing on the fixed frame, with which the ventilation openings to be closed by flaps according to FIG. 1 can be closed.

1, in which a glazed component in the form of a veranda door is shown in plan view, which has a reversible glass pane arrangement 11 and here consists of a rectangular fixed third frame or door frame 13, a movable originally "fixed" but first here There is a frame or door leaf 314 and a second movable frame 318, the second movable frame 318 being pivotable about a vertical rectangular center line 28 within the first frame 314.

To actuate the provided ventilation flaps 110 there are schematically indicated pivot levers 23, while for actuating the pivoting and lifting mechanism to be described in more detail starting points 25, 27 or 29 can be provided for a socket wrench, the socket wrench actuation being advantageous because the window is turned from summer to winter operation will only be required relatively rarely. Instead, too the attachment of fixed handles is possible:

From Fig. 2, a section along the line II-II of Fig. 1, there is a sectional view through the upper and lower horizontal struts of the glazed component, but the door frame 13 is omitted to simplify the illustration. as can be seen from the drawing, the frame or the leaf 314 comprises an upper horizontal spar 34, which forms a U in the cross section which is open towards the bottom and thereby gives you a groove 38 of essentially rectangular shape which serves to accommodate a lifting bar 21 . This lifting bar 21 in turn consists of profiled wood with an H-shaped profile, which forms a funnel-shaped widening groove 45, into which a corresponding spring 47 of the movable frame 318 can engage. This movable frame 318 can be given away with respect to the frame 314, in which the movable frame 318 is first raised by means of a fitting on the lower pivot bearing 86 to such an extent that it fits its groove, which can be seen at the lower end in FIG. 2, from a corresponding lower tongue of the lower one The spar 92 of the frame 314 is released, at the same time the lifting bar 21 is raised by the same amount and then raised further until the groove 45 on the underside of the lifting bar 21 also releases the corresponding spring 47 of the upper horizontal spar 35 of the movable frame 318 Has. So that the frame 318 is freely pivotable about the axis 28 (FIG. 1) and can, for. B. rotated by 180 ° and fixed again.

The glass panes 72, 74 and 76 which can already be seen in FIG. 2 and are more clearly shown in FIG. 3 are constructed such that one of the two outer panes, e.g. B. 72, has a higher energy absorption capacity for solar radiation than it does with the other two panes, e.g. B. 74, 76, is the case. At the same time, this more absorbent pane 72 has, on a pane surface facing another pane 74, a translucent coating made of a material that reduces the emissivity of the coated surface for infrared radiation.

Various types of devices can be used to move the lifting bar 21 up and down and, at the same time, to move the frame 318 up and down with respect to the frame 314.

Thus, a device frequently used in window construction can also be used here, namely spring bands which are arranged in correspondingly provided incisions, see for example the incision 102 (FIG. 2) in a wedge-shaped projection 104 on the bottom of the groove 38 of the upper spar 34, In which incision the spring bands, guided in corresponding envelopes, can be moved axially. At certain deflection points they are then attached to the lifting bar 21 and pull this up or push it down, depending on the actuation of the other end of the spring band.

Another possibility is the actuation with the aid of gear worm gears, which can be actuated via appropriate shafts and deflection gears. both the latter, drive and the spring band are known per se. Hydraulic actuators are also conceivable.

It will have become clear that in order to pivot the movable frame 318, both lifting the frame 318 by a certain amount and lifting the lifting bar 21 by 2-3 times as much is necessary. The lifting bar 21 and the movable frame 318 can be lifted one after the other if there are separate fittings for this purpose, or a simultaneous movement can be carried out if the actuating devices are coupled accordingly, which, however, makes relatively complicated devices necessary because different ways of raising arise and therefore z. B. different gear ratios are required.

The arrangement according to the invention also makes it possible to provide ventilation in a simple manner, the measures necessary for this resulting from FIG. 3, which is a sectional view along the line III-III of Fig. 1 represents.

In principle, it is possible to provide only simple sealing lips on the lateral, vertical spars 108 of the frame 314 and the corresponding side spar 109 of the movable frame 318 and, if necessary, to additionally arrange projections which can be displaced from one frame to the other, but it has been It has proven to be expedient to provide a ventilation arrangement for better air conditioning of a room to be equipped with the glazed component according to the invention, which consists of a ventilation gap 126 which is left between the vertical bars 108, 109 de frame 314, 318. This ventilation gap 126 can be closed by a closure flap 110, which is preferably mounted on the inside of the frame 314 so that it can be pivoted away from the ventilation gap 126 by means of a vertical hinge 118. The flap 110 has first sealing strips 120, 122 with which the lid region of the flap 110 can rest against the end faces of the vertical bars 108 or 109 of the frames 314, 318. Further sealing devices 124 are located within the ventilation gap. The seals 120, 122, 124 give a particularly good seal due to self-locking in the event of wind pressure coming from outside. The flap 110 can be opened and closed by means of the closure devices already mentioned, which can be actuated by handles 23.

As can also be seen in FIG. 3, a U-profile 128 is indicated within the ventilation gap 126, which is made of plastic or metal and is fastened to the frame 314 with its U-profile legs 132 provided with ventilation openings 130, for example by inserting the legs into corresponding grooves. The web 136 of the U-profile 128 serves as a carrier for the sealing strip 113 for contact with the movable frame 318. The openings 130 of the U-profile can be covered with insect gauze 140 on the side facing the side that can be closed by the flaps 110 be covered, or a special attachment 141 is provided for this purpose, which is held interchangeably on the U-profile 128, for example by projections 142. After pivoting away the frame 318 and possibly the flap 110, the U-profile 128 could be pulled out of the slots 134, 136, the gauze 140 renewed and the profile pushed in again, or the attachment 141 could be exchanged.

The space 144 kept clear of the profile can serve to accommodate the actuating devices for the lifting bar 21. Alternatively, a heating device can also be arranged within the U-profile, the z. B. is electrically heated and warms the air entering through the gap.

To prevent driving rain, a mushroom-shaped attachment 145 is used, which is pressed with its foot 147 into a carrier slot 149 of the U-profile 128. Protective walls 151 also emit from the U-profile and extend obliquely covering the openings 130 into the space covered by the mushroom hat.

As can also be seen in FIG. 3, the U-profile 128 is also in two parts, the first parts being connected to one another by a plug connection 153 in the web 138.

The protective walls 151 protrude into the lumen or the mushroom hat only so far that a meandering path 119 for fresh air remains when the door 110 is open.

As can be seen, the U-profile 128 in the web 138 has two undercut grooves which are open to the outside and into which the sealing profiles 113 pointing in the direction of the frame 318 can be inserted. This creates a prechamber 223 for the rain as a drainage channel. The seal 113 itself is designed so that it increases its sealing effect under the influence of pressure. Similar sealing profiles can also be found between frame 13 and door leaf 314, see reference numbers 123 and 125, the door leaf 314 being held in the door frame 13 by means of conventional hinge straps 121, while the flaps 110 in turn are articulated by means of principally conventional door hinges 117 door leaf 314.

Grooves 225 and 227 in frame 314 and in flap 110 are also used to discharge any driving rain that may have penetrated.

An alternative results from FIG. 4, in which a second movable frame 212 is provided on the fixed frame 314, which can be a window or door frame, which holds the first movable frame 318 in the two fixable positions. The second movable frame 212 is laterally on the fixed frame 314, For example, articulated on the vertical spar or strut 108 by means of a special hinge 36, which enables the axis of rotation 38 to be displaced by a certain amount in the direction of the arrows 40, that is to say perpendicular to the plane of the pen. In the one, shown position of the hinge 36, which is close to the fixed frame 314, the second movable frame 212 with a flexible seal 42 lies both on a projecting contact surface 44 of the fixed frame 314 and on a corresponding contact surface 46 of the first movable frame 318 and thereby simultaneously provides a sealing closure for the air gap 126, on the other hand an additional pixelation of the movable frame 318 in the fixed frame 314. If the pivot axis 38 is moved away from the fixed frame 314 in the direction of the arrows 40, the sealing strip 42 will move away from the Remove the support surface 44 or 46 and thereby release an air gap, which preferably extends around the entire window area of the movable frame, but in particular opens an air gap 126 according to FIG. 4, but the second movable frame 212 remains parallel to the first movable frame 318 this position becomes the first movable Frame 318 is no longer held by the second movable frame 212, but the other Z, B in FIG.

As mentioned, the first movable frame 318 is installed in the fixed frame 114 in such a way that this movable frame 318 can either be fixed in the position shown or in a position rotated by 180 ° with respect to this position. To fix this movable frame 318, snap devices can also be provided in addition to the devices already mentioned be that at least provisionally hold the movable frame 318 in these two positions, for example in the form of rubber sealing strips 113, which look like a ventilation grille 128 which is anchored in the strut 108 of the fixed frame 314 in a suitable manner and on corresponding projections or depressions 52 of the first movable frame 318 can hold.

The ventilation grille 128 through which ventilation air can pass can in turn include fly gauze and devices for preventing driving rain, insects, dust or the like, as was shown in FIG. 3.
