EP1740792B1 - Turn-tilt window - Google Patents

Description

The invention relates to a tilt and turn window according to the preamble of claim 1. Such a tilt and turn window is out of EP-A-1323885 known.

In windows of known design of the wing by means of the handle, which is a transmission - in particular a push rod - is connected downstream, which is directly mechanically connected to the handle and acting on locking means for releasing and locking the wing on the frame, opened and closed.

The locking elements of such windows and the fittings for moving the wing, e.g. a tilting bearing, a pivot bearing and a jack are moved circumferentially on the window by means of push rods, which are operated via the window handle. The push rod fittings may be formed, for example, as Stulpschienenbeschläge, in which the push rod is fixed prefabricated under a cuff rail, which is completely inserted into a groove and connected to each other via corresponding Eckumlenkeinheiten. These Stulpschienenbeschläge are relatively expensive mechanically and for the entire bandwidth occurring window is a relatively large and expensive storage required.

For aluminum windows, it has been established that the locking bars are guided as individual components in grooves of the frame profiles and can optionally be equipped with locking elements. In the corner area, the individual push rods must also be connected to Eckumlenkungen to allow the locking of the sash to the frame rails. Although the fitting storage here is less expensive, but the cutting and the processing of the locking bar require a certain effort.

It is also known to open windows by means of electromechanical drives and close. In such windows are used to drive the drives switch. These embodiments have proven themselves. However, the operation is These windows often cumbersome and confusing. By way of example, the generic reference is exemplary EP 1 323 885 A2 directed.

The prior art is further on the parallel-Ausstellfenster the DE 196 03 768 A1 referenced, from which it is known to provide in a parallel-Ausstellfenster between the frame and the wing to be opened in the corner areas on the mutually parallel main surfaces drive modules to couple the fitting system of this window in different operating positions.

Against the background of the generic prior art, the invention is based on the task of further simplifying the assembly and production of windows with electromechanical or electromagnetic components.

The invention solves this problem by the subject matter of claim 1.

Advantageous embodiments can be found in the dependent claims.

According to the characterizing part of claim 1, the at least one functional element is a coupling element which can be activated wirelessly or via electrical lines, these coupling elements being designed to couple the fittings into and out of their functional position, and the frame and the wing are designed to be push-rodless.

The functional elements act as couplings, which disengage the fittings in a functional position and disengage from this, in which the fittings act as a hinge. As a result, a mechanical connection between a control element such as a handle and the fittings omitted, which significantly reduces the cost of producing the tilt and turn window and the need for stocking various components. One between the handle and the locking devices so far mechanical connection to be provided such as a transmission - in particular a push rod transmission - thus eliminates what leads to significant cost advantages.

In the turn-tilt window, it is expedient if at least one of the functional elements is associated with at least the tilting bearing and the rotating belt. The turn-tilt bearing - e.g. provided with a ball socket - is in both window positions "turning" and tilting in function, but does not usually have to be brought via a clutch in various functional positions.

Preferably, as an operating device arranged on the wing handle is provided which has a handle portion movable on the wing in different gripping positions - in particular rotatable - which correspond to different operating positions of the wing, wherein the handle has switching elements and / or sensors and wherein the Handle is connected wirelessly or via electrical lines with electromagnetic or electromechanical locking elements for the wing and / or with the electromagnetic or electro-mechanical functional elements for the fittings and / or with an electromechanical drive device for opening and closing the wing. In particular, the handle is connected to the locking elements and / or the fittings via no mechanical elements such as a gear and the frame and the wings are push-rod formed. The handle is used in a known manner for "operation" of the window. In particular, when the handle is still designed for the manual opening and closing of the wing, the user does not have to familiarize himself with the operation of new control and switching elements, although their use in a turn / tilt window according to the invention is in principle feasible ( eg via a touchscreen or pushbutton or the like).

It is also conceivable according to an alternative embodiment that the window has an electromechanical drive for automatic opening and closing of the wing having. Also in this case, it is advantageous if the operation of the wing is done via a handle, as it is usually used on windows. But especially for cost reasons, the combination of an electromagnetic locking of the window and an electromechanical or electromagnetic coupling of its fittings and a mechanical opening and closing is preferred "by hand", in particular when turning the wing.

According to a further preferred embodiment, a rebate is formed between the frame and the wing and at least one or more of the locking elements are arranged and distributed in or on the rebate, which bridge the rebate and serve the wing on the frame in the closed position of the window to lock, wherein the at least one locking element can be controlled wirelessly or via electrical lines corresponding to the handle position of the handle or other operating device and has an electromagnetically or electromechanically acting closing element. Electromechanical closing elements are made of the DE 195 14 051 A1 known, according to which Einzelverrieglungselemente are provided on a pivotable about a single axis door, which engage in recesses of a frame, in particular a sash and which are unlocked via electromagnets.

According to a further development of the invention, the handle is associated with an electrical monitoring device for detecting the grip position of the handle, which is designed, for example, as a computing unit to detect and output the position of the switching elements or the information from the sensors on the handle. Preferably, the handle is connected wirelessly or via electrical line to the monitoring device. This makes it possible to position the handle and thus the window directly on the window or in a central monitoring station of a building to record and monitor. The monitoring device and the control device can also be integrated into one unit.

Preferably, the handle is associated with an electric circuit directly on the wing, which is expediently and compactly arranged in a handle housing, in particular in the manner of a rosette, or for example on the rebate or in a chamber or recess of the sash.

The wing may be frameless, in which case the handle is attached to the disc. However, the wing preferably has a frame for receiving the handle.

Essential to the handle is that it has the handle part which is designed to be rotated in different gripping positions, which are clearly distinguishable from each other visually, so that the handle positions can also be clearly distinguished from each other functional positions. Especially in this case, the operation of the window is particularly simple without additional controls such as buttons or the like. Would be required.

Otherwise, the configuration of the handle in a variety of ways is possible, in particular in the manner of a loop handle, a rotary handle or the like .. It should always be provided the handle part that is movable in different handle positions, preferably pivotable.

Preferably, the wing on a sash. Likewise, the window frame is preferably but not necessarily circumferentially formed.

As a locking and functional elements come in a particularly advantageous variant electromechanical components in question.

The activation takes place via electrical lines or via a wireless connection, e.g. a radio connection.

Fig. 1 shows a tilt and turn window 1 with a frame 2 and a wing 23, which here has a sash 3 and a disc 24 receives.

The tilt-and-turn window is tiltable about a first axis x, oriented horizontally in the usual installation position, and is rotatably arranged about a second axis y, which is vertical in this case.

For this purpose, the window 1 between the frame 2 and the sash 3 as fittings a Drehkipplager 4, a disengageable tilting bearing 5 and as Drehband ausgestaltetes pivot bearing 6, which is fixed to the sash 3 and releasably fixed to the frame 2.

Depending on whether the window is tilted or turned or whether it is closed, these fittings or here bearings are in their functional position or not. Thus, the tilting bearing 5 is not in tilting movements in its functional position and the pivot bearing 6. For rotary movements, however, the pivot bearing 6 is in functional position and the tilting bearing 5 is not. At the edge of the window, the adjusting device 7 is further provided between the frame 2 and the sash 3 as a further movable fitting, which serves to limit the tilting position of the wing relative to the frame 2.

The rotating belt 6 is releasably coupled depending on the type in the closed position of the window and in the pivotal position about the Y-axis on the frame or on the sash and accordingly fixed to the sash or frame. In the latter case, the pivot bearing 6 and the display device 7 form a unit.

Furthermore, in the in Fig. 1 shown Drehkippfenster a part of the fittings that are needed to realize the mobility between the sash and frame - here the tilting bearing 5 and the pivot bearing 6 and the Ausstellvorrichtung 7 - functionally associated in each case at least one electromechanical functional element 10, 11, 12, respectively the fittings 5, 6 and 7 depending on the control in their functional position on or be disengaged from this to move the wing 23 either in its tilted position or its rotational position or to lock the wing 23 on the frame 2 in its closed position.

The "in-function bringing" or "off-function Bring" the tilting bearing 5 and the pivot bearing 6 via the electromechanically acting coupling elements 10, 11. The electromechanical element 10 controls the tilting bearing 5 between the wing closure position and the wing rotational position about the X-axis on the one hand and the release position for the pivoting position of the wing about the Y-axis.

The electromechanical element 11 ensures the fixation of the pivot bearing 6, which is arranged on the wing 23, on the frame 2 in the wing position and the pivoting movement about the Y-axis on the one hand and gives the pivot bearing 6 on the other hand free in the position of the wing 23 in the X- Axis.

The display device 7 may alternatively be connected to the rotating belt 6, in which case the rotary belt 6 is fixed to the frame 2 and can be coupled via the opening device with the wing 23. Optionally, the opening device 7 can be used via elements not shown here, such as an electric motor and a gearbox - in particular a chain attached to the opening device or a cable for opening and closing the tilt and turn window in and out of the tilted position.

The coupling element 11 ensures release of the pivot bearing 6 on the wing 23 during rotational movements about the y-axis in its functional position. In tilting movements, however, the pivot bearing is set to its deactivated position inoperative. Similarly, the functions of the remaining functional elements 10, 12 with respect to the tilting bearing 5 and the Ausstellvorrichtung 7, whose movements are e.g. be set by electromechanically actuated functional elements with movable bolts or the like. Either out of function and / or disabled or released.

Between the frame 2 and the sash 3 locking elements 8, 9 are arranged in or on the existing between them seaming selectively or only at individual spaced locations of the rebate, which bridge the rebate and serve the wing 23 on the frame 2 in the Close the closed position of the window.

Here, by way of example, three locking elements are arranged on the edge of the wing 23 on the side of the rotating band 6 and on the edge of the wing frame 3, which lies opposite the rotating band 6.

It is also conceivable to provide more of these locking elements 8, 9 on the remaining sides, in particular the top and bottom of the window and / or a different number of locking elements 8, 9. The locking elements 8, 9 are here wirelessly or via electrical lines (not visible here) controlled and have an electromagnetically or in particular electromechanically acting closing element. An electromechanical closing element is preferred in order to produce a sufficiently high closing force, possibly in conjunction with additional translation elements such as tightening bevels, eccentrics, expanding wedges. Here, the closing is preferably by means of the electromechanical drive and the opening electromechanical or preferably u.a. by means of a spring, since i.allg. Opening a window gives you less time than closing and locking.

As an actuating element for the wing 23 is an example of a wing frame 13 arranged handle 13, which has a handle 25 which is movable relative to the frame 3 in different gripping positions on a shaft - is rotatable - is.

The gripping positions of the handle 13 are directly visually distinguishable from each other for a user. In the example provided here for a tilt-and-turn window at different angles, in this case 90 °, different grip positions, the wing 23 is either locked, tiltable or rotatable.

The handle 13 is used here both to tilt the window as well as to rotate, so to apply the mechanical force to move the wing 23 relative to the frame. The handle 13 is not used as usual to operate the locking elements and / or fittings via a mechanism. This task is done here rather without a mechanical connection to the fittings 5, 6, 7 via electrical lines or wireless by the switching position of the handle 13 via a detection device such as switching contacts or sensors (eg reed contacts) detected and for controlling the electromagnetic or electromechanically acting locking and functional elements is used to use the fittings in either the tilting function position or the rotary function position or close the window.

In Fig. 1 the handle 13 is designed such that the downwardly facing handle position corresponds to the closed position of the window, in which all locking and functional elements 8, 9; 10 - 12 are in the locked or closed position.

By contrast, the grip position 16 corresponds to the possibility of displacing the wing 23 into its rotational position, the locking elements 8, 9 and the functional element 10 for the tilting bearing 5 being unlocked in this grip position.

In the rotational position - here in the handle position of the handle upwards - the wing 23 can be rotated against it, so that in this grip position the locking elements 8, 9 and the functional element 11 are unlocked for the pivot bearing 6.

The handle 13 or another (not shown here) operating unit is connected to the locking elements 8, 9 or the fittings on any mechanical elements such as a transmission, in particular a push rod assembly connected. By eliminating a mechanical transmission connection between the handle and the locking elements and fittings of the effort for the production of the window is lowered and on the other hand, the possibility created by wireless or other connection of the handle or the handle assigned Switching and / or sensor elements to transmit the detected grip position to a parent - not shown here - monitoring device, so that it is possible, for example, to centrally detect and monitor the position of the windows of a building without additional sensors between glare and sash.

The switching and / or sensor elements of the handle 13 and possibly further electrical or electronic components such as interface modules to a data and / or power bus of a building automation system can according to an advantageous variant of the invention in a handle housing 14 - outwardly formed as a rosette - be housed without the visual impression is changed over conventional purely mechanical acting handle adversely.

Alternatively, it is also conceivable - not shown here - to accommodate an electrical circuit for the handle 13 in or near the handle 13, so in the rebate, a chamber or in a recess of the sash.

The handle 13 on the one hand allows the usual handling of the window and on the other hand - depending on the design - used due to their electronics with sensor and / or switching elements as a switching and / or information module.

Fig. 2 shows another example of a handle 18 for a tilt and turn window. In the Fig. 2 handle shown has a loop handle 19 which is rotatable or tiltable in the manner of a rocker relative to a handle 23 attached to the housing 23 in different gripping positions. In the position indicated by the reference numeral 19, the window is closed, in the position marked 20, it can be placed in its tilted position and in the position marked 21 of the handle 18 in its rotational position.

Depending on the size of the wing, the number of locking elements varies. In a tilt and turn window smaller design at least one locking element 11 is required. Primarily, a locking element on the handle side vertical frame member 29 is provided. For larger window sashes and taking into account the window installation positions 3 further locking elements may be provided on the four frame beams 29 - 32 of the sash frame 3, which lock the wing quasi selectively or in places.

Instead of the handle 13, the Drehkippfenster the Fig. 1 theoretically, switching elements of another type such as buttons or the like. Have and / or a control unit other than in the rosette. However, the handle 13 is preferred as a particularly simple handling and operating element and is combined with the associated control circuit to form a functional unit.

Fig. 3 shows a section through a frame of a window with frame 2 and sash 3, wherein in the rebate 26 of the locking elements 8, 9 is shown schematically, which is electromechanically actuated. The locking elements 8, 9 each comprise an electromechanically driven, movable locking slide 27 which is movable in the direction of the disk plane in the direction of the sash 23 and in its locking position fixed to the wing or relative to the wing 23 not movable Verrieglungswiderlager 28 as a roll or a Bolt engages behind.

A schematic representation of such a locking device 8 'in different operating positions shows Fig. 4 ,

Fig. 4 shows a purely schematically illustrated electromechanical drive device 33, which is an electric motor and preferably a downstream of this transmission has (not shown here individually). This drive device 33 is preferably arranged on the frame (or alternatively on the wing).

To Fig. 4 the locking slide 27 are provided with control cams, in particular Anzugsschrägen 34 such that the wing 23 is pulled when locking with a predetermined force over a path "c" in the direction of the frame 2, so that the wing 23 rests with predetermined force close to the frame 2.

The gear allows the linear movement of the locking slide 2 in its axial direction or in the direction of the corresponding window part - here the wing 3 - and in the direction of the movable wing - not shown here - fixed locking abutment 28th

At the locking abutment 28 facing side of the locking slide 27 is a control cam, here a Anzugsschräge 34 is formed, which can also be formed on a radially integrally formed on the actual Verrieglungsbolzen and only over a part, in particular an end portion of the locking slide 27 extending projection 35.

The function of this arrangement is as follows.

When closing the window, the locking slide 27 from a retracted position ( Fig. 4a ) extended from the frame 2 in the direction of the sash 3 until the locking slide 27 comes with its Anzugsschräge 34 at the outer radius of the locking abutment 28 to the plant ( Fig. 4b ). If the locking slide 27 is further extended, the locking abutment 28 on the wing 3 and the wing 3 itself are pulled perpendicular to the disc plane in the direction of the frame 2 until a locking position is reached, in which the Way the suit slope 34 is completely traversed, so that the closed position can be maintained even when energized motor (locking position of the Fig. 4c ).

For unlocking, according to an alternative, the closing path along the tightening slope 34 can be traversed back (not shown).

However, in order to perform the opening of the wing as quickly as possible, it is also conceivable to extend the locking slide 27 until it reaches a position at which it slides past the projection 35 with the Anzugsschräge 34, so that the wing 23 particularly fast from Can solve frame 2 ( Fig. 4d ).

The path "a" to be traveled linearly by the locking slide 27 in its direction of displacement when the window is locked is significantly longer than the distance "b" to be traveled during unlocking before opening (the ratio of a / b is in particular greater than 2/1), so that the time that is necessary until the window after pressing the control element, in particular after twisting the handle 13, is unlocked and can be opened, is shorter than the time required by the drive to the window after the example manual closing and subsequent rotation of the handle 13 to lock. This is advantageous because in particular the opening should always go quickly, whereas the user does not bother a longer time to lock after closing the window or after applying the wing to the frame 2.

An alternative embodiment shows Fig. 5 , Here the locking takes place analogously to Fig. 4 but unlocking by means of an unlocking spring 36.

A drive housing 37 for the electric motor and a transmission is in this case designed such that it also receives the unlocking spring 36, in particular a helical spring.

The unlocking spring 36 surrounds the locking slide 27 and is supported on two stops 38, 39 which surround the locking slide 27 concentrically, wherein one of the stops 38 surrounds the locking slide 27 like a disk and is axially fixed thereto and the other as the housing wall 40 of the drive housing 34th is formed, which passes through the locking slide 27 movable. On a projecting from the drive housing 37 projection 41, a head part 42 of predetermined length is formed, which in turn is provided with the Anzugsschräge 34.

The locking takes place as after Fig. 4 but wherein in the drive housing 37 at the end of the locking slide 27 an eccentric is formed with an eccentric pin 43 which moves on a circular path 44 and acts on closing on a radial stop 45 on or around the locking slide 27 which is firmly connected to the locking slide 27 is, so that the eccentric pin on the stop 45, the locking slide 27 to the outside from the drive housing advances (to the locking position of the Fig. 5c ).

If the eccentric pin is moved further, it slips past the edge of the stop 45, so that in turn the locking abutment 28 is released, so that the unlocking spring 46 can relax.

To Fig. 5b on the other hand, the circular path 44 of the eccentric pin 43 is so dimensioned and tuned that after less than half a circular path 44, the closed position is reached and that the further sweeping the circular path 44 of the locking slide 27 further extends until it again reaches a position at which the Headboard 42 is released, so that the wing 23 in turn the head part 42 is released, so that the wing 23 in turn can quickly detach from the frame 2 ( Fig. 5d ).

Kinematic reversals, for example, with control cams on the locking resistors are also feasible. Likewise, the electromechanical drive in the wing and the abutment are placed on the frame.
