Opening device for an at least parallelable and in this position horizontally displaceable wings of a window or a door.

The invention relates to an opening device for an at least parallelable and in this position horizontally displaceable wings of a window or a door after the

Preamble of claim 1.

There have already been proposed fittings of the generic type, in which the

Ausstellarme Ausstellvorrichtung by the releasable locking device are also securely fixed in their Parallelabstelllage when the engaging with the control lug of the support lever in operative connection abutment is provided only in the sliding-Schließendbewegung the wing on the fixed frame.

In DE-C- 36 38 356, the support lever consists of a carriage on the only pivotally mounted, two-armed lever which carries the control approach at the end of the fixed frame facing the lever arm, while the hinged to the Ausstellarm lever arm is pivoted exclusively hinged to a connecting plate, which also pivots on the extension arm attacks. The connecting link and the attacking on her lever arm of the support lever together form a toggle, which necessarily via the control approach of the support lever and the frame-side abutment by the sliding-Schließendbewegung the wing at least from the Parallelabstelllage of the or the Ausstellarme blocking extended position between the carriage and the Ausstellarm in a releasing kinked hereto is convertible. The advantage of this embodiment is that an unintentional and undesirable triggering of the locking device is effectively prevented until reaching the sliding-Schließendbewegung the wing by in the trajectory of the support lever arrived or brought objects, because the locking device only has pivot joints, which in the direction of sliding -Schließendbewegung the wing staggered one behind the other and are therefore influenced by existing obstacles only in the direction of locking. In the other case of DE-C- 36 43 964, the connecting strap is also designed as a two-armed lever, with her over the hinge on the extension arm protruding lever arm pivotally mounted on a pin in a wing located on the pivot

Guide slot engages, which is provided at its the Parallelabstelllage the wing associated end with a locking receptacle for the pin. In the Parallelabstelllage the wing here acting on the hinge on the extension arm lever arm of the connecting tab acts as an additional support member which counteracts an angular rotation of the wing-side bearing of the stay and therefore significantly improves the holding function of the jack.

On the one hand, the angularly mounted on the carriage pivotally mounted angle lever and on the other hand, the frame-side abutment comes without a detent claw with distance upstream guide curve for the operation of the angle lever. In addition, it has proved to be particularly advantageous if the wing-side detent of the guide slot has a bent towards the carriage or fixed frame out position while their end portion at an acute angle to the main direction of the

Guide slot is inclined and that the frame-side abutment has an inlet opening for the control approach, followed by a bent in sliding-closing direction of the wing against the fixed frame towards curved slot.

The invention has for its object, with little effort and at low cost to provide a display device on a parallel Schiebekipp- or sliding windows or doors, with a generic kinematic design with the generic

Ausstellvorrichtung cooperating locking device of the sliding-Schließendbewegung ensures a safe closing of the wing.

This object is achieved by a parallel Schiebekipp- or sliding window or a - door with a frame and a relative to the frame between a closed position and at least one movable in a parallel opening position wings with the features of claim 1.

A particularly useful development is seen in the fact that the support lever a on the extension arm in the area between the articulation point on the carriage and the articulation point on

Wing hinged only pivotally hinged, two-armed lever which engages with a seated at the end of the wing lever arm associated guide pin pivotally displaceable in a guide slot located on the wing, which at his the Parallelabstelllage of the wing associated end with a locking receptacle for the

Guide pin is provided, while at the freely movable end of the carriage facing the lever arm designed as a pin control approach is provided, which can be brought by the sliding-Schließendbewegung the wing with the seated on the fixed frame abutment in operative connection with this and relative to the carriage through the wing-side guide slot in Lock engagement position is fixed, the

Abutment on the control approach (pin) directed side has a ramp surface. In this case, the lever arm connected to the control lug is preferably designed to be elastically movable perpendicular to the horizontal spar of the wing. This allows the control approach to move automatically by the movable version of the lever arm perpendicular to the sliding movement. In normal operation, the control approach moves with reaching the sliding-Schließendbewegung the wing in an inlet opening of the abutment and is transferred with automatic triggering of a locking device in a curve slot, wherein the wing moves into a closed position to the frame. By arranged on the abutment ramp surface and arranged on the movable lever arm control approach, the wing can be controlled in an advantageous manner before reaching the sliding closing movement even with unintentional and undesired triggering of the locking device, with striking the control approach (pin) to the ramp surface in the Transfer the cam slot of the abutment. Thus, the wing is transferred when moving in the closed position in each befindlichem distance to the frame in the closed position. Even with one

Faulty switching of the fitting or the display device or misalignment of the wing to the frame, the wing can be converted by the arranged on the abutment ramp surface, in a closed position in normal operation set position.

It proves to be useful for the reliability of the release device that the frame-side abutment has the inlet opening for the control approach (pin), followed by the curved in slot-closing direction of the wing against the fixed frame curved curve slot, which is on the outside the abutment surface is the cam slot at least until the end of the cam slot transverse to the mounting surface of the track in the direction of fixed frame follows. The control approach (pin) bridges the height difference of the bottom surface of the cam slot and the large area on the abutment arranged ramp surface

Inlet opening to the surface of the abutment and engages with reaching the surface of the repository immediately automatically into the curve slot.

It is also advantageous that the ramp surface perpendicular to the central axis of the control lug (pin) is formed by the approach forming an outer side to the surface of the abutment increasing. This allows the pin with negligible

Impact resistance to the ramp surface and during the transition over the ramp surface in transfer the cam slot with low frictional resistance.

Simply designed and effective for a cost-effective and safe variant for a stable normal operation of a parallel sliding wing as Schiebekippflügelsystem or sash wing system of a window or a door with a Ausstellvorrichtung proves the abutment accordingly, that the ramp surface beveled designed as a chamfer, wherein in the assembled state of Ausstellvorrichtung with the abutment of the beginning of the approach of the ramp surface under the free end of the control lug (pin) is arranged and before triggering contact of the control approach to the ramp surface of the approach is arranged next.

Thus, it has proved to be advantageous to the function, installation and cost of the fitting that the Ausstellvorrichtung zugefahrener one hand in the open Parallelabstelllage the wing to the frame with reaching the sliding-Schließendbewegung or on the other hand with triggered locking device before reaching the sliding-Schließendbewegung

Ausstellvorrichtung and thereby reduced distance of the wing to the frame, in

Active connection through the control approach with the abutment arranged ramp surface an automatic transfer of the control approach takes place in the cam slot and transferred the wing in the closed position to the frame. Regardless of the size and weight of the window or the door acts

Ausstellvorrichtung by the advantageous embodiment described above functionally safe and smooth.

Preferred embodiments of the invention are shown schematically in the drawing and are explained below with reference to the figures of the drawing. Show it:

Fig. 12 is a corresponding plan view of the carriage according to Fig. 1 1.

FIGS. 1 to 6 of the drawing show a window or a door which, in a fixed frame 1, has a fixedly mounted wing 2 or a fixed door panel and which are also equipped with a movable wing 3. The movable wing 3 can be brought, on the one hand, into the tilted position, relative to the fixed frame 1 and the fixedly mounted wing or door panel 2, from the closed position indicated in FIGS. 1 and 2, as shown in FIGS. 3 and 4. 4 can be seen. In a further embodiment or by other components of the fitting, the wing 3 can be compared to the fixed frame 1 and the fixed mounted wing or fixed door panel 2 but on the other hand bring in a secured parallel parked ventilation position or in a parallel parked position, then the wing 3 from the field of Through hole 4 of the fixed frame 1 in the horizontal direction in front of the fixed built-in wing or the fixed door panel 2 is displaceable, as shown in FIGS. 5 and Fig. 6 can be seen. So that these four positions of the wing 3 are possible relative to the fixed frame 1 as well as to the permanently mounted wing or fixed door panel 2, a special fitting arrangement, namely a so-called parallel sliding tipping wing system or sliding wing system is provided between the wing 3 and the fixed frame 1, of which in FIG. 1 to FIG. 6, for the sake of simplicity, only one operating handle 5 on the wing 3 and one upper opening device 6 and lower opening device 7 between the wing 3 and the stationary frame 1 can be seen.

From the kinematics forth, the upper Ausstellvorrichtung 6 and the lower

Ausstellvorrichtung 7 be designed similar. However, the basic structure of the upper Ausstellvorrichtung 6 can also be derived from those types, as they are used for windows or doors with tilt or Drehtippflügel so and belong to the prior art. It only has to be ensured that the frame-side articulation points of this

Ausstellvorrichtungen constantly engage in a horizontal sliding guide 8 on the upper cross member of the fixed frame 1 and a synchronous movement of their extension arms is secured. The lower display device 7 must be designed in each case so that it carries the weight of the movable wing 3 safely while the display device 7 cooperates with a running rail 9 of FIG. 1 to 12 at the lower cross member of the fixed frame 1. In the present case, it depends mainly on the design and operation of the lower display device 7, the functionally essential embodiment in Figs. 7 to 12 can be seen.

The display device 7 has at least two identical opening arms 10, of which, however, only one is shown in FIGS. 7 to 12 for the sake of simplicity.

Each extension arm 10 is hinged about a substantially vertical axle 1 1 pivotally mounted on a carriage 12.

Each carriage 12 is provided with two substantially horizontal axes freely rotatably mounted rollers 13 by means of which the carriage 12 is supported on the running rail 9 of the fixed frame 1 movable parallel to its plane. Each extension arm 10 carries at its other end a bearing pin 14 which engages only pivotally mounted in a wing 3 bearing block 15, as is particularly clear from Figs. 7 to 12 can be seen. The support arms 10 carrying the carriage 12 are connected to each other via a coupling rod 16 in a fixed connection, which is only partially shown in FIGS. 7 to 12. With the help of the coupling rod 16, the axle bolts 1 1 and the carrying carriage 12 of the display device 7 are kept constantly at a constant distance from each other.

Also, the bearing pins 14 of the two extension arms 10 engage at a constant distance from each other on the wing 3, namely in the rigidly fixed thereto bearing blocks 15, such that the wing 3, the carriage 12 with the coupling rod 16 and the two

Ausstellarme 10 together form a Lenkerparallelogramm. With the help of this

Lenkerparallelogramms, the wing 3 can be adjusted transversely to its own plane and also transversely to the plane of the fixed frame 1 between the closed position shown in Fig. 8 and the apparent from Fig. 10 Parallelabstelllagen. While in the Fig. 8 corresponding adjustment of the display device 7, a movement of the wing 3 from the FIGS. 1 and 2 corresponding closed position in the apparent from Figs. 3 and 4 Kippöffnungsstellung is possible, the wing 3 in the Parallelabstelllage the display 7th are pushed horizontally in the apparent from FIGS. 5 and 6 opening position.

Thus, the wing 3 relative to the fixed frame 1 during his

Horizontal displacement constantly remains safe in the Parallelabstelllage relative to the fixed frame 1, it is necessary to block the Parallelabstelllage at least the Ausstellarme 10 of the lower display device 7 relative to the fixed frame 1 and guided on its running rail 9 carriage 12 by a special locking device 1 7 which can be clearly seen in FIGS. 8 and 10. On the other hand, the blocking of the Parallelabstelllage for the Ausstellarme 10 must be canceled by triggering the locking device 17, however, as soon as the wing 3 reaches its sliding-Schließendstellung so that it from the Parallelabstelllage of FIG. 9 in the closed position relative to the

fixed frame 1 can reach, as indicated in Fig. 8.

For simplicity, a locking device 17 is provided only between the closing side lower Ausstellarm 10 and the wing 3 and the fixed frame 1, although it would be quite possible to provide in the region of both Ausstellarme 10 between the wing 3 and fixed frame 1 such a locking device 17. Due to the forced interaction of both Ausstellarme 10 in the manner of a

Lenkerparallelogramms, however, it is sufficient, the releasable locking device 1 7 only in Provide area of the closing side Ausstellarms 10 between the wing 3 and the fixed frame 1.

The locking device 17 has a support lever 18 which is articulated pivotably about a bearing pin 19 on the extension arm 10, and approximately in the central region between the axle 1 1 on the carriage 12 and the bearing pin 14 on the bearing block 15, as can be seen in FIG ,

The support lever 18 is designed as a two-armed lever with the fixed frame 1 facing lever arm 18 a and the wing 3 facing lever arm 18 b. At the end of the wing 3 facing the lever arm 18b carries the support lever 18 of FIG. 8, a guide pin 20 which is pivotally displaceable in a wing 3, in the

Bearing 15 located guide slot 21 also shown in FIG. 8 engages. Also, the fixed frame 1 facing lever arm 18a of the support lever 18 is provided according to Fig. 7 to 12 with a pin 22 as a control approach, which is associated with the fixed abutment 23 on the fixed frame 1 and on the running rail 9.

The frame-side abutment 23 in this case has an inlet opening 24 for serving as a control projection pin 22 of the support lever 18, to which a bent in sliding-closing direction of the blade 3 against the fixed frame 1 towards curved slot 25 connects, as shown in FIGS. 8 and 10 emerges.

Located on the wing 3 and on the bearing block 15 guide slot 21 is provided at its the Parallelabstelllage (Fig. 10) of the wing 3 associated end with a locking receptacle 26 for the guide pin 20 on the lever arm 18 b of the support lever 1 8, which against the fixed frame 1 or the carriage 12 bent toward course and connects via a guide arc 27 to the guide slot 21. The flank 28 of the locking receptacle 26 extends at an acute angle of less than 90 ° to the longitudinal direction of

Guide slot 21, as can be clearly seen in FIG. 8 and FIG. 1 0, so that the guide pin 20 can engage in the paralleleposition of the wing 3 to the frame 1 of FIG. 1 0 in the locking receptacle 26.

The closing position of the blade 3 associated end of the longitudinal slot 21 in the bearing block 15 of FIG. 8, has an obtuse bend 30, which is the fixed frame 1 and the carriage 12 is facing.

When lying in the closed position on the fixed frame 1 wing 3 is the Guide pin 20 of the support lever 18 in the region of the obtuse bend 30 of the guide slot 21, while the pin 22 thereof is located in the region of the fixed frame 1 facing the end of the cam slot 25 on the frame-side abutment 23, as shown in FIG. 8 can be removed.

The length ratios on the one hand of Ausstellarmes 10 between its axle 1 1 and its bearing pin 14 and the bearing pin located therebetween 19 for the support lever 1 8 and on the other hand, the support lever 18 between the guide pin 20, the pin 22 and the bearing pin 19 are chosen so that in the Parallelepstellbewegung of the wing 3 from the position of FIG. 8 in the position of FIG. 10 is a very specific forced movement of the support lever 18 is controlled, while the guide pin 20 of its lever arm 18b longitudinally displaced within the wing-side guide slot 21.

As long as the guide pin 20 has not reached the guide bow 27 before the locking receptacle 26, namely the support lever 1 8 is guided in its spreading movement relative to the extension arm 10 so that the pin 22 of its lever arm 18 a almost always in the vicinity of the fixed frame 1 facing End of the cam slot 25 in the frame-side abutment 23 remains. During this, therefore, the wing 3 is fixed by the support lever 18 so relative to the fixed frame 1, that it is held against a horizontal displacement from the region of the through hole 4 thereof.

Only when the guide pin 20 in the guide slot 21 on the locking receptacle 26 upstream Leitbogen 27 strikes, the support lever 18 to the bearing pin 19 on

Extending arm 10 gradually pivoted so that the pin 22 of its lever arm 18a enters the region of the inlet opening 24 of the frame-side abutment 23 and thus can be detached from the frame-side abutment 23. At this moment, however, is already the

Guide pin 20 run into the locking receptacle 26, and is in front of its acute angle to the wing plane extending edge 28. Thus enters the locking device 17 in

Form-fitting engagement and supports the extension arm 10 on the wing 3 and on its bearing block 15 against turning back around its bearing pin 14 from. The Parallelabstelllage of the wing 3 relative to the fixed frame 1 and to the running rail 9 movable carriage 12 is thus effectively blocked. Functionally, it has proven particularly useful if the flank 28 of the locking receptacle 26 according to FIG. 8 and FIG. 10 has a course that coincides with the

Pivoting arc of the guide pin 20 to the bearing pin 1 9 covers the stay 10, when the extension arm 10 relative to the wing 3 takes the position corresponding to Parallelabstelllage angular position about the bearing mandrel 14.

It has further proven to increase the reliability of the locking device 17, when the support lever 1 8 is supported against the extension arm 10 by a spring element, such as a leaf spring 29, in such a manner that a stop 31 on the lever arm 18a of the support lever 18 approximately at a time on the leaf spring 29, in which the guide pin 20 of the lever arm 18b has reached the Leitbogen 27 of the guide slot 21. The leaf spring 29 can thereby give the support lever 18 a movement impulse, which presses the guide pin 20 of the lever arm 18b in the locking receptacle 26 and thus the

Locking device 17 is operated in the locking direction.

In normal operation, the control approach moves with reaching the sliding-Schließendbewegung the blade 3 as described above into the inlet opening 24 of the abutment 23 and is transferred with automatic triggering of the locking device 17 in the cam slot 25, wherein the wing 3 moves into the closed position to the frame 1 ,

By additionally mounted on the abutment 23 ramp surface 34 and arranged on the movable lever arm 18 control lug 22, the wing 3 can be in an advantageous manner before reaching the sliding closing movement even with unintentional and unwanted triggering of the locking device 17, with striking the control lug (pin) 22 guided to the ramp surface 34 controllably guided into the cam slot 25 of the abutment 23. Thus, the wing 3 is transferred in moving into the closed position of FIG. 1 1 and FIG. 12 in each befindlichem distance to the frame 1 in the closed position. Even with one

Faulty switching of the fitting or the display device 6, 7 or misalignment of the wing 3 to the frame 1, the wing 3 can be converted by the abutment 23 arranged ramp surface 34, in one of the closed positions in normal operation set position of Fig. 7 and Fig. 8 , For this purpose, the frame-side abutment 23, the inlet opening 24 for the control approach (pin) 22, to which in the sliding-closing direction of the wing 3 against the fixed frame 1 curved curve slot 25 connects, with the directed to the carriage 12 outside the abutment 23 located run-flat surface 34 the curved slot 25 at least until the end 35 of the cam slot 25 transverse to

Mounting surface of the running rail 9 in the direction of fixed frame 1 follows. Of the

Control approach (pin) 22 bridges the height difference of the bottom surface 39 of the cam slot 25 and the inlet opening 24 to the surface 40 of the abutment 23 by means of the large area on the abutment 23 arranged ramp surface 34 and snaps with reaching the

Surface 40 directly automatically into the cam slot 25 a. The ramp surface 34 is formed perpendicular to the central axis 36 of the control lug (pin) 22 of the approach 37 forming an outer side to the surface 40 of the abutment 23 rising. This allows the pin 22 with insignificant impact resistance to the Transfer ramp surface 34 and during the transition over the ramp surface 34 in the cam slot 25 with low frictional resistance.

As can be clearly seen in FIGS. 7, 9 and 11, the run-on surface 34 is chamfered in the form of a bevel, wherein in the assembled state of the display device 7 with the abutment 23, the beginning of the projection 37 of the run-on surface 34 under the free end 38 of FIG

Control approach (pin) 22 is arranged and before triggering contact, the control lug 22 on the ramp surface 34 the approach 37 is arranged next.

Thus, on the one hand, the opening device 7 together with the opening device 6 in the open Parallelabstelllage the wing 3 to the frame 1 with reaching the sliding closing movement or on the other hand with triggered locking device 17 before reaching the sliding Schließendbewegung zugefahrener Ausstellvorrichtung 7 and thereby reduced distance of the wing 3 Frame 1, in operative connection by the control lug 22 with the arranged on the abutment 23 ramp surface 34, by automatically transferring the control lug 22 in the curved slot 25 of the wings 3 in the closed position to the frame 1 convict.

Thus, the wing 3 relative to the fixed frame 1 with its lower cross member can not reach in Parallelabstelllage when it should be opened as shown in Fig. 4 in tilted position, are between the lower horizontal spar of the wing 3 and fixed frame 1 special locking devices of the tilt -Parallelabstell sliding stops provided, which interlock so that they the lifting movement of the wing 3 transversely to its plane relative to the fixed frame 1 on the only for the

Restrict tilting movement necessary minimum dimension. These locking devices can receive a training, as is common in tilt locks for tilt and turn windows and doors.

It is particularly advantageous that the wing-side bearing blocks 15 for the opening arms 10 from a - not shown in the figures - tubular extruded profile can be made, which has a substantially polygonal, in particular rectangular or square, cross-section. Preferably, this extruded profile can be made of light metal. At its lower longitudinal side, the bearing block 15 has a plate 32 which holds the guide slot 21 with the bend 30, the guide bow 27 and the

Locking receptacle 26 contains. The plate 32 can be clamped within an undercut channel in a predetermined position or secured against displacement by screws or pins against displacement, which engage in holes of the plate 32. LIST OF REFERENCE NUMBERS
