Fitting for at least one tiltable sash of a window _t i

a door or the like 1

The invention relates to a fitting for a little ^y

least tiltable sash of a window, door or the like., wherein

the upper wing end over two laterally spaced, |

Extension arms with at least rotatable bearings at both ends with an f

Fixed frame od. The like. Is connected and the two extension arms are coupled to one another by means of a link. The latter causes the associated upper wing end to be guided parallel to one another, which is intended to ensure that the upper wing transverse spar is as parallel as possible approaching the upper transverse spar of the fixed frame or the like when the tilted wing is closed. Such positively controlled constructions used par- fy particular transferred into the tilted position or is moved from the tilt in the closure position with simpler hardware, in which the wings of unlocking with the turning handle of the closure. If the parallel position of the said spars is not guaranteed, the upper wing corner removed from the operating handle does not run in properly or it jams in the rebate. This can then lead to a pre-closing of the lock.

In a known fitting of the type mentioned at the outset, the two extension arms are attached to so-called gliders on the frame side.

steered, which a lateral pushing away of the tilted or parallel parked Ensure the wing. The two extension arms are coupled there on the frame side by means of a connection of the two gliders. This through the articulation axles on the frame side the two extension arms and the two articulation axes of the link on the sliders parallelogram runs in the closing end movement of the sash extremely flat. Because there must be a certain amount of play in fittings and this also applies to the bearing points is already known in this case

Fitting shortly before reaching the closed position, perfect parallel guidance is no longer guaranteed. As a result, a so-called pre-locking with this fitting, especially with wide sashes, cannot be ruled out.

The object of the invention is consequently darrin to improve a fitting of the aforementioned type so that even at f \ the usual tolerances proper parallel guidance is to the closed position of the wing, but also ensured in the opposite direction, and thereby the so-called preclose is prevented.

To solve this problem, the invention proposes that the fitting according to the preamble of claim 1 accordingly the characterizing part of this claim is formed. The effort is not greater with this fitting than with the previously known, however, the flat parallelogram, especially

avoid special ones shortly before reaching the closing end position. Consequently Even wide sashes are perfectly guided in parallel up to the closing end position. There is therefore no pre-closing nor to a jamming in the closing end phase. In this solution, the handlebar is in front of the so-called wing rollover, however, this is insofar of no importance as in the case of such fittings the extension arms are in any case resting on the rollover are mounted and they are normally covered by means of a profile extending over the entire width of the wing

will. The latter then also covers the handlebars. Therefore in this direction arises neither from the effort nor from the aesthetic Impression of a night file.

A Weiterbilciunc the Erf indunc ¹ provides ■ the two ö.s.ß f LII gelseiiigen axes of rotation of the extension arms and the axes of rotation dos link closed wing a parallelogram having almost right angles form. The exact right-angled position of this imaginary parallelogram is deliberately avoided for the usual reasons, but the short parallelogram sides a run through the right-angled position during the opening movement, and then assume an inclined position to the other side in the course of the further opening movement. Overall, however, there is no flat parallelogram in any of the possible end positions or intermediate positions, as is known from the known prior art. Therefore, the perfect parallel guidance is maintained over the entire pivoting movement of the extension arms.

Another embodiment of the invention is characterized in that that each extension arm is widened at its wing-side end is, wherein it has in particular a lateral bearing eye for the pivot axis of the link. The size of the bearing eye depends on the width of the extension arm, measured across the plane of the sash, and it is also on the strength of the Holms dependent. The bearing eye or the widening must ensure that the axis on the handlebar side lies in front of the plane of the wing comes because, as I said, the handlebars are in front of the

facing surface of the associated wing crossbar is located.

Another variant of the invention is characterized by a latching device that is effective at least in the extended position of the extension arm for each extension arm. F has taken when the end of the wing in question od its maximum distance from the fixed frame. The like., The locking device is to automatically come into operation in order to prevent a pivoting back of the respective Ausstellarae and thus the undesired closing movement. However, the latching device can also be designed in such a way that it secures both the closed position and the open position.

A preferred embodiment of the invention provides that the locking device consists of a locking member, in particular a locking lug the extension arm, and a locking element on the wing. The locking element is expediently made of plastic, wherein you can achieve a resilient behavior of the in particular by appropriate choice of material and shape as well as dimensioning P.astelements strives for. During the pivoting movement, the locking member or the locking lug automatically moves in the direction of the notch of the locking element and then occurs in the pivoting end position of the extension arms and possibly also in the - 'position of the latter automatically into the locking recess of the rasp element. In the event of a double-acting locking device then two locking receptacles are available with which the locking lug in the associated Pivot end position of the relevant extension arm engages. From-

education can be done so that from a predetermined position of the associated extension arm on the one hand a moment in the closing direction and when opening the sash a moment in the opening direction takes effect. The latching member is expediently latchable against the force of a loading spring and is therefore special effective.

Γ A preferred variant of such a fitting with an additional wing that can be folded down in parallel is characterized in that the two extension arms of the lower wing end are also connected by means of a link. The articulation of the upper and lower extension arm pairs on the sash and frame is carried out in an identical manner and this also applies to the coupling of the two sashes gel-sided extension arm ends by means of an upper and a lower link. On the frame side, however, the lower extension arms are not articulated to so-called scissor sliders or comparable elements, but to a lower carriage. As a result, the wing can not only be tilted, but can also be parked in parallel and, in a particularly preferred manner, when using scissor-type gliders and trolleys, at least in the parallel storage position, it can be pushed sideways in front of a fixed field or a second wing, in particular a so-called cleaning wing. From this it follows that you can either tilt or fold the wing or, with simultaneous pivoting of all four extension arms, you can also park it directly in parallel after unlocking. The same applies to closing the sash. In any case, it is guaranteed that the upper and lower wings

gel bars exactly parallel to the corresponding bars of the fixed frame or the like. Be moved into the closed position or into the fully open position. A pre-closing is held by four extension arms, parallel retractable sash with a handlebar on only the upper extension arms safely prevented. The relative rotation of the extension arms with respect to their handlebars takes place via corresponding Rotary axes that can be rotated either on the handlebar or on the extension arm

are held firmly. If you have the non-rotatable connection on the handlebar

provides, so is only a simple storage on the extension arm necessary. As a result, the extension arms can be used with a fitting with or without a handlebar. this I is very accommodating to production in large series.

FIG. 5 shows a plan view of the wing according to FIG. 4.

In a fixed frame 1, a wing 2 is tiltable (FIG. 2) and can be set down in parallel (FIG. 3) and is slidably mounted in front of a second wing 3 in the parallel set-off position. The transfer from the unlocked closed position (Fig. 1) in the tilted position and fl \ e parallel offset is preferably carried out by pulling the handle 4, the f \ is rotatable in a gear box 5, wherein the rotary movement serves in known manner to the engaged or disengaged and is transferred to connecting rods 6. So-called corner deflections 7, which are located on all four wing corners in the exemplary embodiment, transmit the vertical movement of the connecting rods 6 or connecting rod halves to further horizontal connecting rods. The latter is used to actuate locking elements that interact with strikers on the fixed frame.

If the user turns the handle 4, for example from the position shown in FIG. 1, by 90 ° in the direction of arrow 8, move it the locking members not shown in detail in their striker plates. The like. And you can then then by pulling on the handle in the direction of the room inwards the wing into one Tilt position and subsequently in a parallel storage or bring it straight into the latter.

Interlocking with the fixed frame.

In order to ensure parallel guidance of each horizontal wing cross member with respect to the associated cross member of the fixed frame, especially when closing the sash in the direction of arrow 9,
the fitting is equipped with a special parallel guide. As can be seen in particular from FIG. 5 in conjunction with FIG
The wing of the version that can be parked in parallel takes cents
Connected to the fixed frame 1 both at its upper and lower end by means of an upper pair of arms 10 and a pair of lower arms 11. Each pair consists of a first extension arm 12 on the lock side and a second extension arm 13 parallel thereto. The first extension arm 12 is rotatably mounted on the wing about an axis 14 and on the fixed frame about an axis 15 parallel thereto. The corresponding axes of each second extension arm 13 are denoted by 16 and 17. the
The frame-side mounting of the extension arms 12 and 13 takes place on the upper cross member 18 of the fixed frame 1 on so-called scissor glides 19 and 20, which are in a running rail 21 in the sense of
Double arrow 22 are slidably mounted. In contrast, the frame-side mounting of the lower deployment arms takes place on carriages 23 and 24, which are slidably mounted on a lower running rail 25, which extends approximately over the width of both wings.

At a distance from each wing-side bearing axis 14 or 16 is

det is a bearing pin 26 or 27 running parallel to this. It connects the relevant end of the extension arm with the associated one End of a link 28. This runs parallel to the associated cross member 18 or 29. Each link 28 is the cross member upstream to the interior of the room and it runs parallel to this. The bearing pins 26 and 27 are either in the extension arm or rotatably mounted in the handlebar. If they are secured against falling out, they can advantageously also be used in both elements store rotatable.

DiLa both axes 14 and 16 as well as the two axes 26 and 27 mark the corners of an imaginary parallelogram. In Fig. 5, the relative position of the axis 26 to the axis 14 is in the closed Wing 2 indicated by a dashed circle 38. It can be seen that the corners of the parallelogram in both rotary end positions of the extension arms come very close to a right angle. This is especially true for the closed position of the sash. In this way

is a safe guide, especially in the final phase of the transfer of the sash, given from the tilted or parallel parked position to the closed position.

To create the necessary space for axes 26 and 27, the extension arms 12 and 13 are widened at their wing-side end, in particular provided with a bearing eye 30.

In order to secure the tilted or parallel position in particular, there is an extension arm end at each sash-side

a latching device 31. This consists of a latching member 32, in particular a latching lug of the extension arm 12 or 13 and a Latching element 33 aiii wing 2 with a latching receptacle 34 for the latching member 32. The latching element 33 is preferably made of plastic manufactured and the locking receptacle 34 is located on a spring elastic evasive web 35 of the locking member 32. The Behälthisse are chosen so that the resilient engagement in The direction of the open position of the wing 2 acts.

In a manner not shown, one can also have a closed Wing locking latching device of this type can be provided, which then causes a moment in the closing direction in the end phase .

Instead of a nose-like locking member molded onto the extension arm 32 one can also provide a slidably mounted locking glider which can be pressed in against the resistance of a loading spring is.

So that the handlebar 28 can not move in the longitudinal direction, its two ends are each in an advantageous manner Clamping screw 36 or 37 or another known element suitable for this purpose secured. The clamping screw is in a corresponding, in the longitudinal direction of the axis 26 or 27 extending thread can be screwed. As such, there would be a shift lock on only one axle (26 or 27) are sufficient, but securing them on both axles brings assembly advantages.
