Description

The present invention relates to a window or a door with a frame and a sliding sash.

From the DE 100 52 093 it is known to use sound generators for soundproofing on columns of open window frames. Described are a device and a method for increasing the soundproofing of partially open windows such. B. windows in the tilted position, partially open sliding or sash windows and skylights, where a) in the area of the resulting through the partial opening between the outer and inner window frame opening slot of the incident sound by sound generators such. g. loudspeakers or similar, with an anti-sound field superimposed in such a way that it is reduced, b) the incident noise is measured using one or more microphones, c) the loudspeakers and microphones in the inner window frames and/or in the external window frame and/or in the masonry surrounding the window or a similar type of reveal, and d) the microphone signals are fed back to the loudspeakers via a controller (feedback arrangement). The structure known from the prior art makes sense per se, but it has been shown that it can only be integrated into windows with relative difficulty.

The prior art is also the generic KR 2008 0109449 A called.

Based on the prior art mentioned, the invention has the task of realizing improved ventilation on sliding elements. According to a further development, the problem described above is then to be eliminated.

The invention solves this problem by the subject matter of claim 1. It also provides the method of claim 14.

According to claim 1, a window or a door is created with a first sliding sash that is displaceably arranged in a window frame, wherein next to or in addition to the first sliding leaf, a second sliding leaf is provided, which has at least one opening integrated into the second sliding leaf for ventilation.

It is further advantageously provided that the second sliding sash is arranged in a storage compartment, from which it can be moved out of a closed position in the storage compartment into a ventilation position, in which the opening - in particular the through-opening transverse to the plane of the sash - can be traversed by air, and in that it can be moved into a closed position, so that the passage opening is closed.

With the subject matter of claim 1, the ventilation on sliding windows and doors is significantly simplified, since the sliding sash offers an integrated ventilation option. This ventilation opening can advantageously be closed and opened again, in particular by moving the sliding sash. The opening passes through the sliding leaf, preferably transversely to the main plane of the leaf (perpendicular to the sliding direction). It preferably has a cross section that can be used for ventilation, so that an adjoining room in a building can be ventilated to a significant extent.

According to a further development, it can be provided that the second sliding leaf has at least one device for active soundproofing—NC device—assigned to the at least one opening.

A facility with which in itself after the type of DE 100 52 093 but more generally at any opening on a window or a door, in particular at a through-opening, active soundproofing is achieved with the sound generator, microphone and controller described above is used in the claims and below as a device for active soundproofing and in short as an NC device (Noise-canceling device) called. It can have one or more microphones and one or more sound generators at the opening and one or more controllers in the sense of electronic control.

With the subject matter of claim 2, the task of ventilation and active soundproofing is no longer implemented at an interface between an immovable window frame and a movable casement frame, but the ventilation and active soundproofing are integrated in a second sliding wing provided in addition to the first sliding wing. The problems that arise when the device for soundproofing is also to be provided at an interface between a movable sliding sash and a stationary window frame that is also to be sealed in a burglar-resistant and possibly thermally insulated manner when it is closed are eliminated.

The second sliding sash is a complete sliding sash, ie a sash that can be moved into at least two positions on a window frame. Provision can be made for it to be attachable on its one, preferably vertical, side to be coupled to the first sliding leaf.

It can be provided that the at least one opening in the second sliding leaf is designed as a through-opening passing through the second sliding leaf perpendicular to the sliding direction, in particular as a ventilation gap and/or a ventilation channel.

It can further be provided that the second sliding sash can be moved from a closed position, in which the opening is closed at least on one side, into a ventilation position, in which the opening is open. It is then advantageous if the sliding sash, in the closed position, moves into a screen which is provided at least on one side of the opening and which closes the opening at least on one side.

In this case, it can advantageously be provided that the receiving compartment closes the ventilation opening at both of its ends in the closed position. In this way it is also possible in a simple manner to move the ventilation opening with the NC device into a protected position in which it and the NC device provided on it are well protected from the effects of the weather.

It can also advantageously be provided that the second sliding sash - apart from the opening, is also thermally insulated and passively soundproofed, in order to achieve the sound insulation on the one hand and the thermal insulation on the other - realized, for example, by a composite construction with or made of panels and heat and sound insulation strips to be further optimized in the area of this door element.

It can advantageously be provided that the second sliding wing can be detachably coupled to the first sliding wing in such a way that the first sliding wing and the second sliding wing can be moved together from the closed position into the ventilation position. This is particularly useful when the first and second sliding sash are in a common plane.

Provision can also advantageously be made for the first sliding wing to be displaceable separately from the second sliding wing after the coupling to the second sliding wing has been released. In this way, an opening of any size can be realized between the first and the second sliding leaf, which can be used, for example, as a passage.

The actual non-moving window frame can be closed or non-closed.

It is also conceivable, according to a further development, that the first sliding sash, in a state decoupled from the second sliding sash, can also be moved into a rotary position and/or a tilted position in addition or as an alternative to separate sliding.

To simplify handling, provision can be made for the second sliding leaf to be assigned a motor drive which acts on the second sliding leaf and which is designed to move the second sliding leaf by a motor. It can also be provided that the motorized drive is designed to move the second sliding leaf together with the first sliding leaf by a motor. This is advantageous in that a single drive in a simple way to moving two sliding panels. It can be provided that the electric motor drive is integrated into a window frame profile.

It is advantageous and structurally simple to implement if corresponding coupling elements are provided for the coupling between the first sliding leaf and the second sliding leaf. This may resemble a coupling between two pivoting leaves of a window that is closable and releasable.

A switching device for releasing and closing the coupling between the first sliding leaf and the second sliding leaf can also be provided.

It is advantageous if the switching device has at least one sensor, in particular a magnet switch, for detecting the position of one or more magnets, which can be moved by a switch-actuating element in order to generate different switch positions.

It is also simple and advantageous if a movable handle, in particular a rotatable handle, is provided on the first sliding wing as the switch-actuating element, with which the first sliding wing can optionally also be moved manually separately from the first sliding wing.

It can further be provided that the handle is coupled to a locking bar, which has locking elements as coupling elements for locking and releasing the coupling.

The terms window and door are used synonymously below. Terms such as top and bottom and left and right refer to the illustrated installation situation, which is preferably to be understood as an example. In the case of rotations and/or displacements of the installation situation in space, these must be transferred or transformed accordingly.

In Fig. 1a a door 1 with a frame 2 and a first sliding leaf 3 is shown.

The window frame 2 can be closed on the circumference or not closed on the circumference. In the representation of Fig. 1a the frame 2 is designed to be closed around the circumference, for example. Here it has two vertical bars 2a, 2b and two horizontal bars 2c, 2d. The lower vertical beam 2d here forms a kind of step and floor sill as well as a guide rail 5 and a cover for a space below the guide rail 5 .

The first sliding wing 3 is here designed to be displaceable relative to a fixed element 4 in the horizontal direction. It essentially extends in a vertically oriented plane. The term "horizontal" also refers here to the plane of the drawing Figure 1a . The first sliding panel 3 is movably guided on a guide rail 5 . This guide rail 5 also forms part of the lower frame member 2d here. The first sliding panel 3 preferably extends to the upper frame member 2c, on which it can also be guided.

All frame members 2a-2d can be constructed in several parts and preferably in a composite construction.

The door 1 also has a second, horizontally movable sliding panel 6 . This in turn extends in a substantially vertically oriented plane. The term "horizontal" also refers here in turn to the plane of the drawing Figure 1a . The first sliding leaf 3 is also movably guided on the lower guide rail 5 and preferably extends to the upper frame spar 2c, on which it can also be guided.

The second sliding leaf 6 has at least one opening 7 or more openings. The opening 7 is designed as a through-opening passing through the second sliding leaf 6 perpendicularly to the sliding direction. The cross section of the at least one opening 7 can be designed in different ways. Here it is designed like a slot or even like a slit. It preferably forms a ventilation channel and has a channel-like extension between the two outer sides of the second sliding leaf. In this canal area can be beneficial and easy Additional devices such as heat exchangers for heating or cooling, loudspeakers, tweeters for deterring insects and/or fans can be arranged. A rectangular shape is also preferred. At least one NC device 9 is assigned to the opening. This can preferably be designed in the sense of the definition given for the claims.

It can preferably be provided that the opening 7 extends over more than 50% of the distance between the upper and lower window frame spar 2c, 2d and that the width perpendicular thereto is between 5 and 30 mm. In this way, a particularly advantageous reduction in the sound passing through the opening or an increase in the soundproofing against sound which would otherwise pass through the opening 7 unhindered in any case in a sash sliding position perpendicular to the plane of the drawing can be achieved.

The second sliding leaf 6 is arranged in a receiving compartment 8, from which it can be extended into a ventilation position in which air can flow through the through-opening transversely to the plane of the leaf, as is shown in 1c is shown. This storage compartment 8 can be formed between the one vertical window frame spar 2a or the like. And the first sliding leaf 3 .

The second sliding panel 6 can be moved into a closed position in the storage compartment 8, so that the opening 7 of walls 8a, 8b of the storage compartment, which can extend parallel to the plane of the sliding panel of the door, can be closed. This is in the Figures 1a and 1b shown and particularly well in the 2 recognizable.

The second sliding panel 6 can also be extended out of the storage compartment 8 into a ventilation position, so that the at least one opening or one, several or all of the openings exit perpendicular to the main plane of the two sliding panels from the region of the walls 8a, 8b of the storage compartment and air can flow through them is (see Figure 1c ). Since the NC device 9 is arranged at the opening 7, active soundproofing can be carried out in this way. The ventilation position is therefore also a soundproofing position when the NC device 9 is activated.

According to a preferred variant, the second sliding leaf 6 can be coupled to the first sliding leaf 3 in such a way that the first sliding leaf 3 and the second sliding leaf 6 can be moved together from the closed position of the second sliding leaf 6 into the ventilation position of the second sliding leaf 6, as is shown in 1c is shown.

According to a particularly preferred variant, the second sliding leaf 6 can also be detachably coupled to the first sliding leaf 3 in such a way that the first sliding leaf 3 and the second sliding leaf 6 can be moved together from the closed position of the second sliding leaf 6 into the ventilation position of the second sliding leaf 6. like this in 1c is shown, but it is also possible, after releasing the coupling, to open only the first sliding leaf and to leave the second in the receiving compartment 8 .

After the coupling to the second sliding leaf 6 has been released, the first sliding leaf 3 can be provided so that it can be displaced separately from the second sliding leaf 6 . this is in Fig. 1b shown.

Alternatively or according to an optional variant, both sliding leaves 3, 6 can also be moved together or coupled to the extent that the second sliding leaf 6 is moved further or even completely out of the receiving compartment 8, as is shown in Fig. 1d is shown. This function is used for maintenance and repair purposes of door 1.

In 2 or in the enlargement in 3 a plan view of the door 1 is shown in section. Here it can be seen how the second sliding panel 6 is completely accommodated by the storage compartment. The opening 7 is closed on both sides.

It is easy to see that the first sliding leaf 3 is narrower here perpendicular to the sliding plane than the second sliding leaf 8. On their mutually facing, connectable sides, the two sliding leaves 3 and 8 have a corresponding geometry and preferably corresponding connectable Functional elements, so that the gap or fold between the wings 3 and 6 can be closed tightly.

The first sliding wing 3 preferably has a wing frame 30, which can consist of a plurality of frame bars 31, 32, 33, 34, it being possible for a surface element such as a pane of glass to be inserted into the frame. Another window can also be integrated into the first sliding leaf 3 itself.

The first sliding panel 3 can also be constructed as a rotating panel or rotary tilting panel. Then, on the one hand, it can be moved together with the second sliding sash 6, but if it is decoupled from it, it can alternatively or additionally also be turned open and/or swung open (not shown here, corresponding rotating hinges and, if necessary, a deployment mechanism or the like are then required). . necessary).

The second sliding leaf 6 can be constructed in various ways. For example, it can have a wing frame and a surface element inserted therein. However, it can, for example, also have a composite profile 60 which extends vertically only towards the first sliding leaf 3 .

It can otherwise or alternatively have a type of box-shaped structure, with stabilizing plates 61, 62 made of plastic or sheet metal and one or more heat and sound insulation strips 63, 64 being provided, which together form or form the box-shaped second sliding leaf. In the area of the through-opening 7, one or more of the plates 61, 62 can be designed, for example, as perforated plates, which line the opening 7 at its edge area.

The frame profile 31-34 and/or 60 is preferably made of a metallic material, and the frame profiles are particularly preferably made of a light metal such as aluminum. Alternatively, the frame profiles can also be made from a plastic material.

The second sliding leaf 6 has at least one NC device - ie a device 9 for active sound insulation - on.

The NC device 9 for active noise insulation works according to the principle of active counter-noise generation with a frequency spectrum that is matched to the noise emission and is in phase opposition, so that the intensity of the noise emission is reduced and is therefore perceived as less disturbing, or the intensity of the noise emission is reduced to such an extent that that ideally it is no longer perceived. Such a device 9 for active soundproofing is known from the prior art (see e.g DE 100 52 093 A1 ) and is therefore not described in detail here.

The door 1 can thus be brought into a ventilation position through the opening 7 in the second sliding leaf 6 and the device 9 for active soundproofing, with possible noise emissions acting on the door 1 from the outside being effectively reduced or insulated.

A switching device 10 - in particular a mechanically and/or electromechanically and/or electromagnetically acting switching device 10 - can be provided for releasing and closing the coupling - realized, for example, by mechanically acting corresponding coupling elements - between the first sliding leaf 3 and the second sliding leaf 6.

The switching device can have at least one sensor, in particular a magnetic switch, for detecting the position of one or more magnets, which can be moved by a switching actuation element. The switching device 10 has a lever 11 as the switching operating element.

The switching device 10 can also have one or more sensors or magnetic switches 12, with which various switching positions can be sensed and switching signals can preferably be output to a control device (not shown). The sensor 12 is designed here as a magnetic switch. The sensor 12 can also be designed differently (see also 3 ). The lever 11 is inserted into a wing frame of the first sliding wing 3 . The sensor 12 can inserted into the frame bar 60 of the second sliding sash 5 (see also figure 5 ) and aligned in the direction of folding to the first sliding panel 3.

In Figure 4a the lever 11 on the first sliding leaf is shown in different switching positions. In an upward, vertical switching position of the lever 11, the switching device 10 is in a locked position. This can mean, for example, that the first sliding leaf 3 is closed in this switching position. The sensor 12--here a magnetic switch--of the switching device 10 corresponds or is aligned in this case with a first magnet 13a, which can be moved by the lever 11 and is correspondingly mechanically coupled to it. The magnet 13a is inserted into the sash frame 30 of the first sliding sash 3 (see Figure 4b ). The terms "vertical" and "above" refer to the plane of the drawing Figure 4a .

A display 14 that informs an operator about the current switching position of the switching device 10 can be present in the leaf frame of the first sliding leaf 3 or at another suitable position on the door 1 . The information about the current state of the switching device 10 is provided here visually via a light source 15. The light source 15 can advantageously be embodied as an LED. It can be envisaged that it lights up when locked, while it does not light up when unlocked (see Figure 4d ).

In a horizontal switching position of the lever 11, the switching device 10 can be in a ventilation position. This means that in this switch position the first sliding leaf 3 is coupled to the first sliding leaf and the second sliding leaf 6 is moved out of the receiving compartment 8 with this, so that the opening 7 can be freely traversed by outside air. In this state, the NC device 9 is also preferably activated.

In this case, the first sliding leaf 3 and the second sliding leaf 6 are coupled to one another. In this case, the sensor 12 - the magnetic switch - of the switching device 10 can be aligned with a second magnet 13b, which is also inserted in the casement frame of the second sliding casement 6 (see FIG Figure 4c ) and is vertically movable by the lever 11.

In a downward, vertical switch position of the lever 10, the switching device 10 can be in an open position. This means that in this switch position the first sliding leaf 3 is open or can be opened. In this case, the first sliding leaf 3 and the second sliding leaf 6 are not coupled to one another. In this case, it can be provided that the sensor 12 of the switching device 10 is not connected to a magnet 12a, 12b (see Figure 4d ) curses. The terms "vertical" and "below" refer to the plane of the drawing Figure 4a .

In the Figures 6a and 6b the door 1 is shown with the unlocked first sliding panel 3 and the second sliding panel 6, which is fully retracted into the receiving compartment 8. In Figure 6a and better recognizable in Figure 6b , It is shown that the lever 11 also acts on a fitting 16 with which the first sliding leaf 3 can be mechanically locked on the second sliding leaf 6 .

The wing profile 60 is with the fitting 16 in the Figures 7a to 7c shown. The fitting 16 has a locking bar 17 which is vertically displaceable in a U-profile. The U-profile is fixed in or on the first sliding panel 3 . The locking bar 17 has openings 18 which correspond to hook-like locking elements 19 and cause the first sliding leaf 3 to be mechanically held closed or the second sliding leaf 6 to be mechanically coupled to the first sliding leaf 3 when the fitting is in the locked state. The term "vertical" refers to the plane of the drawing Figures 7a to 7d .

In the Figures 8a and 8b the second sliding leaf 6 is shown. Two carriages 20 can be seen here on this sliding leaf 6. Each carriage 20 here has a plurality of rollers 21 which are rotatably mounted in the carriage 20. The second sliding sash is slidably guided on the guide rail 5 via the rollers 21 . The first sliding leaf 3 (not shown here) also has a number of carriages 20 for this purpose.

In the Figures 9a to 9d the guide rail 5 with the second sliding leaf 6 is shown in section. the Figures 9a and 9b show the second sliding sash in a closed position, or completely in the storage compartment 8 (here not shown) retracted while the Figures 9c and 9d show the second sliding panel 6 in an open position or in a ventilation position.

In figure 10 the area of the guide rail 5 is shown.

In the Figures 11a to 11c it can be seen that the motor drive 22 is assigned to the second sliding leaf 6 or acts on the first sliding leaf 6 . Except for a coupling element for coupling to the second sliding leaf 6, it can essentially advantageously be arranged below the guide rail 5 in the space provided there. For this purpose, the drive 22 is fastened with its connecting rod 23 to a shoe 24, the shoe 24 being guided on the guide rail 5 and being fastened to the second sliding leaf 6 (not shown here). The drive 22 is intended to move the second sliding leaf 6 together with the first sliding leaf 3 coupled to the second sliding leaf 6 by motor.

The drive 22 works according to an electrical operating principle and is designed here as an electrical lifting cylinder. Alternatively, the drive 22 can also work according to a fluidic principle of action.

In Figure 11a the drive 22 is shown in a position in which the second sliding leaf 6 is closed or is fully retracted into its receiving compartment 8 . In Figure 11b the drive 22 is shown in a position in which the second sliding panel 6 is open or in a ventilation position. In 11c the drive 22 is shown in a position in which the second sliding leaf 6 is fully open for maintenance and repair purposes or is fully extended from its receiving compartment 8.

In 12 the door 1 is analogous to Fig. 1a shown in a three-dimensional view with the second sliding panel 6 closed and the first sliding panel 3 closed. 13 shows door 1 analogous to Fig. 1b in a spatial representation with the closed second sliding panel 6 and an open first sliding panel in a passage position. In 14 the door is shown in a position in which the second sliding leaf 6 is open in a ventilation position analogous to 1c is shown and the first sliding leaf 3 is open in a passage position.
