• and in which the guide pin of the locking device can be engaged and disengaged relative to the snap-in receptacle by means of an abutment seated on the fixed frame by the sliding movement of the wing.

A generic fitting for horizontally displaceable The wing of doors, windows or the like is already known from DE 37 11 170 A1. It has also been put into practical use already tried and tested because it differs from one Different fitting according to DE 32 34 677 A1 differs that the triggerable locking device for the Extension arm completely decoupled from the one in storage Carriage works. He uses a two-armed lever that on the extension arm in the area between the articulation point on Carriage and the articulation point on the wing exclusively is pivotally articulated and with one at the end of the Guide pin attached to the wing of the lever arm swiveling into one on the wing Guide slot engages while at the end of the carriage the tax approach is provided towards the lever arm, which in the abutment relative to the carriage by the wing-side guide slot in locking engagement position can be locked. Because of a single articulated Connection between the extension arm and the carriage when fitting according to DE 37 11 170 A1 in an advantageous manner causes the stresses to occur on both of rollers of the carriage carried on the running rail can be distributed evenly and in the same direction. It this prevents the carriage from tilting, while at the same time due to the rigid two-point support of the Display device on the wing by removing the Elasticity behavior a safe force absorption can be guaranteed.

A fitting developed further than DE 37 11 170 A1 is disclosed in EP 0 504 677 A1. It can save space and structurally simple design not only that of his Carriage completely independent holding, positioning and Control connection with the wall opening or frame side stationary ramp or control surfaces and / or the Allow backup intervention. Rather, it guarantees at the same time in its parallel position Wing assigned functional position a rigid in itself Two-point support of the wing against its plane against the extension arm. For this, two become one piece with each other Hook lever firmly connected to a two-armed lever used their common bearing axis at a distance from the pivot axis of the extension arm on the carriage Have extension arm. There are two on the second hook lever Curved longitudinal edges facing away from each other with the Runway surfaces of two seated on the wing, with respect to the Wing plane staggered longitudinally and transversely arranged guide pin in continuous engagement during the first hook lever over its pin - in the sliding end position of the wing - with the against the fixed wall opening bent cam slot of the safety intervention in Engagement is held. The respective areas of the Guide pin and the associated curved longitudinal edges form the second hook lever with respect to each other assigned areas and additionally interacting areas Control surfaces for the first hook lever. The respective Surfaces of the pin and the cam slot form with reference ramp surfaces assigned to each other to the first hook lever and additional interacting control surfaces for the second Hook lever while the one facing the wall opening curved longitudinal edge on the second hook lever in one The hook's mouth ends, the one of the two pins on the wing provided guide pin assigned as a fixing engagement is. The second hook lever runs with its curved Long edges between the bearing axis and the hook mouth approximately curved like a sickle, with the direction of curvature in the area closer to the bearing axis from the wall opening away and in the area adjacent to the hook mouth this extends out.

This feature set makes it special smooth-running and low-wear design of the Generic fitting created. However, since the size the necessary hardware components are limited itself curved by the arrangement of the sickle-like certain longitudinal edges on the wing-side hook lever certain Restrictions on the design of the movement curve for the wing at its transverse to the wall opening level directed parking movement.

Ensuring all the fittings according to DE 37 11 170 A1 and EP 0 504 677 A1 are aimed at particular advantages Invention mainly based on the Design freedom for the movement curve of the wing of his to and perpendicular to the wall opening plane Extend the parking movement.

According to the invention, this object is achieved by the features

• that the two-armed lever with its lever arm facing the carriage constantly covers a steering arm,
• that this steering arm is axially offset with one end but is parallel to the two-armed lever on the extension arm and is free with its other end in front of the carriage and in the movement path of the fixed abutment,
• that this steering arm has a constant coupling curve connection between its two ends with the lever arm of the two-armed lever covering it,
• that this coupling curve connection can be actuated by the length portion of the extension arm which is delimited between the two bearing axles by the two-armed lever and the steering arm and is effective in the manner of a double knee joint,
• that the steering arm carries a catch hook or the like at its free end,
• and that the catch hook can be brought into and out of action by the coupling curve connection of two-armed lever and steering arm with the stationary abutment when sliding the wing.

This feature set according to the invention provides sure that there is a movement dependency between that with the fixed abutment interacting steering arm and that of the triggerable locking device assigned to the wing Lever arm of the two-armed lever is retained. This However, movement dependency does not result from one one-piece fixed connection, but can be by Variation of the provided coupling curve connection - within certain limits - to different needs vote.

It has proven itself according to the invention, the Coupling curve connection by a pair of curves and a To form support pair. Here, the pair of curves can Steering arm are located while the pair of support links on the Steering arm covering lever arm of the two-armed lever is arranged. The system is easy to move the invention in that the pair of support members from around pins rotatable rollers or sleeves is formed.

In a particularly advantageous manner, the invention can Pair of curves formed by outline boundary edges of the steering arm whose transverse distance from each other differs from that Bearing point of the steering arm on the extension arm towards free end of the steering arm enlarged.

After all, it has proven to be particularly useful when the Carriage-facing curve of the pair of curves on the steering arm, for example C or J-shaped and relatively flat and long is executed while the curve is turned away from the carriage it has an approximately flat S or Z-shaped course and one has a relatively short length.

1 to 6 of the drawing show a balcony or Patio door, which in a fixed frame 1 one has fixedly mounted wings or a fixed door panel 2 and which is also equipped with a movable wing 3 is.

The movable wing 3 can be relative to the fixed Frame 1 and the fixed wing or door panel 2 the closed position indicated in FIGS. 1 and 2 on the one hand be brought into the tilt opening position, as in the 3 and 4 can be seen. He can be compared to that fixed frame 1 and the fixed wing or fixed door panel 2 but also in one bring parallel parked position and then out of the area of Through opening 4 of the fixed frame 1 in Horizontal direction in front of the fixed wing or that move the fixed door panel 2, as in FIGS. 5 and 6 can be seen.

So that these three positions of the wing 3 relative to fixed frame 1 and to the fixed wing or fixed field 2 are possible, between wing 3 and the fixed frame 1 a special one Fitting arrangement, namely a so-called tilt-parallel parking sliding fitting provided by the 1 to 6 for the sake of simplicity only the Operating handle 5 on wing 3 and the upper one Display device 6 and the lower display device 7 between wing 3 and fixed frame 1 hinted you can see.

The upper display device 6 and the lower Display device 7 can be kinematically similar to one another be interpreted. But you can also fundamentally received different configurations. At the top Display device 6 must ensure that their frame-side articulation points in a horizontal Sliding guide 8 on the upper cross member of the fixed frame 1 constantly intervene and a synchronous movement of their Extension arms is secured.

The lower opening device 7 is in any case to be interpreted as the weight of the movable wing 3 carries safely while running with a track 9 at the bottom Crossbar of the fixed frame 1 cooperates.

In the embodiment, it mainly comes up Training and mode of operation of the lower one Issuing device 7 comprehensive fitting, namely insofar as it concerns the structural and functional Design of at least the lower closing side Display device 7 goes.

Both the closing-side and the opening-side lower one Display device 7 has an extension arm 10 such as the one shown 7-10. Each of these extension arms 10 is about a substantially vertical axle bolt 11 pivoted to a carriage 12. Both Carriages 12 are each with two around essentially horizontal axes of freely rotatable rollers 13 equipped, by means of which they are on the running rail 9 of the fixed frame 1 parallel to its plane support movable.

The extension arm 10 carries one at its other end Bearing mandrel 14, which is only pivotable into one on the wing 3 attached bracket 15 engages, as that of FIG. 7 can be seen.

The two carriages 12 carrying the extension arms 10 stand with each other, e.g. B. via a coupling rod 16, in fixed Connection that is only partially and dash-dotted in Fig. 7 is indicated. With the help of this coupling rod 16 the axle bolts 11 or the carriage 12 carrying them Display device 7 constantly at a constant distance held to each other. The bearing pins 14 of the two Extension arms 10 therefore grip at a constant distance to each other on the wing 3, namely in the rigid attached bearing blocks 15. Wing 3, the two Carriage 12 with the coupling rod 16 and the two Extension arms 10 together form a handlebar parallelogram. With the help of this handlebar parallelogram, the wing 3 across its own level and also across the level of fixed frame 1 between that defined by FIG. 8 Closed position and the parallel parking position recognizable in FIG. 13 adjust, he also those shown in FIGS. 9 to 12 Intermediate positions.

While in the position shown in Fig. 8 Display device 7 easily a movement of the wing 3 from the FIGS. 1 and 2 corresponding closed position in the 3 and 4 apparent tilt position is possible can the wing 3 in the parallel storage corresponding position of the opening device 7 according to FIG. 13 horizontally into that shown in FIGS. 5 and 6 Open position can be moved.

So that the wing 3 relative to the fixed frame 1 during its horizontal displacement is always safe in the Parallel storage compared to the fixed frame 1 remains, it is necessary to park this parallel at least the two extension arms 10 of the lower Display device 7 relative to the fixed frame 1 or compared to those guided on its running rail 9 Carriage 12 through a special locking device 17 block that particularly clearly in FIGS. 12 and 13 is recognizable.

On the other hand, by triggering this locking device 17th blocking the parallel storage position for the extension arms 10, however, can be canceled automatically as soon as the wing 3 in its horizontal movement the sliding closing position reached in front of the through opening 4 so that it is then relative to the fixed frame 1 from the parallel storage area 13 can get into the closed position according to FIG. 8.

For the sake of simplicity, a locking device 17 only between the lower lower arm 10 on the closing side and the wing 3 and the fixed frame 1 or Carriage 12 provided, although it would be entirely possible such locking devices 17 in the area of both Extension arms 10 between sash 3 and fixed frame 1 to provide.

Due to the forced interaction of both extension arms 10 in the manner of a handlebar parallelogram is enough completely off, the triggerable locking device 17 only in Area of the closing arm 10 between the To provide sash 3 and the fixed frame 1.

The locking device 17 has a two-armed lever 18 on that around a bearing pin 19 exclusively is pivotally articulated on the extension arm 10, namely approximately in the middle area between the axle pin 11 on the carriage 12 and the bearing pin 14 on the bearing block 15.

The two-armed lever 18 has a fixed frame 1 facing first lever arm 18a and one wing 3 facing second lever arm 18b, these lever arms 18a and 18b are integral with each other and have free ends facing away from each other.

At the free end of the lever arm 18b facing the wing 3 there is a guide pin 20 which is pivotally displaceable in one on the wing 3, namely in the bearing block 15 Guide slot 21 engages. The fixed frame 1 facing lever arm 18a of the two-armed lever 18 is close equipped at its end with a pair of support members 22 which by two pegs 22a and 22b is formed with predetermined Distance 22c are next to each other and preferably each rotatably support a roller or sleeve 22d or 22e.

The two lever arms 18a and 18b of the two-armed lever 18 are in a certain aspect ratio to each other, that is about 1: 2 in the embodiment shown.

The lever arm 18a of the two-armed lever 18 acts via Support member pair 22 not directly with a stationary Abutment 23 on the fixed frame 1 or on the Track 9 together. Rather, is for this purpose Special steering arm 37 is provided, the lever arm 18a of the two-armed lever 18 constantly covered. This steering arm 37 is at one end around a bearing pin 38th offset, but parallel to the two-armed lever 18 am Raised arm 10 stored while at its other end carries a pin 39, and with this freely in front of the carriage 12 and in the movement path of the fixed abutment 23 lies.

The steering arm 27 has a between its two ends constant coupling curve connection 22/40 with him overlapping lever arm 18a of the two-armed lever 18. The Coupling curve connection 22/40 is on the one hand by the Pair of support members 22 on the lever arm 18a and on the other hand by one Pair of curves 40 formed on the steering arm 37. As a pair of curves 40 Coupling curve connection 22/40 are shown in the Embodiment certain length ranges of the outline boundary edges the steering arm 37 used. The carriage 12 facing curve 40a stands with the pin 22a or roll or sleeve 22d carried therefrom in permanent contact, while the curve 40b facing away from the carriage 12 with the Pin 22b or the roller or sleeve 22e thereof carried in Permanent contact is kept. The curve 40a of the pair of curves 40 has an approximately C- or J-shaped curvature as well as relative flat and long course, while curve 40b flat-S- or Z-shaped is contoured and is proportionate has short length. It can also be seen that the transverse distance of curves 40a and 40b of curve pair 40 in the direction from Bearing pin 38 of the steering arm 37 on the extension arm 10 away in Direction towards the free end of the steering arm and that the Coupling curve connection 22/40 in the functional position of the 8 the largest and in the Functional position of the fitting according to Fig. 13 the smallest Distance from the bearing pin 38 for the steering arm 37 on the extension arm 10 has.

The formed by the pair of support members 22 and the pair of curves 40 Coupling curve connection 22/40 between the lever arm 18a of the two-armed lever 18 and the steering arm 37 is by the the two bearing axles 19 and 38 of the two-armed lever 18th and the steering arm 37 limited and thereby in the manner of a Double knee joint effective length portion 41 of the extension arm 10 actuated as soon as and as long as the one acting as a tax rate Pin 39 of the steering arm 37 with the fixed abutment 23 on fixed frame 1 is engaged. For this purpose the frame-side abutment 23 has an inlet opening 24 which one against in the sliding closing direction of the wing 3 the fixed frame 1 bent curve slot 25 connects, as can be seen in each of FIGS. 8 to 13.

Due to the dimension of the longitudinal part 41 on the extension arm 10 between the two bearing axles 19 and 38, through the Length ratio of the lever arms 18a and 18b of the two-armed Lever 18 and by the design of the coupling curve connection 22/40 between the lever arm 18a and the steering arm 37 the movement characteristics of the wing 3 in the Guide slot 21 engaging guide pin 20 determined. It is only indirectly dependent on the movement of the Pin 39 set at the free end of the steering arm 37 while this with the inlet opening 24 and the cam slot 25 of the frame-side abutment 23 in positioning and holding engagement stands.

It is obvious that the movement characteristics of the guide pin 20 assigned to the wing 3 Variation of the length ratios between the two lever arms 18a and 18b of the two-armed lever 18, through Dimensional variation of the longitudinal part 41 of the extension arm 10, as well as by varying the coupling curve connection 22/40 between the lever arm 18a and the steering arm 37 to more or can adapt to different needs. In all Rule, or in most cases, it is entirely sufficient only the configuration of the coupling curve connection 22/40 vary by changing the shape of the curves 40a and 40b at the outline boundary edges of the steering arm 37 is made. According to the different Therefore, only the steering arm 37 may need to be replaced.

The one on the wing 3 or on the bearing block 15 Guide slot 21 is at its parallel storage position (Fig. 13) of the wing 3 associated end with a locking receptacle 26 for the guide pin 20 on the lever arm 18b of the two-armed Lever 18 provided. This has one against the fixed one Frame 1 or to the carriage 12 bent course and connects to the guide slot 21 via the elbow 27.

The flank 28 of the locking receptacle 26 extends at an angle of less than 90 ° to the longitudinal direction of the guide slot 21, as can be clearly seen in FIGS. 12 and 13 can. The area of flank 28 opposite Locking seat 26 is designed as an extension 29, so that the guide pin 20 in the locking receptacle 26 with radial Game can intervene in the direction of expansion 29.

The end of the associated with the closed position of the wing 3 Longitudinal slot 21 in the bearing block 15 has an obtuse angle Bend 30 on the fixed frame 1 and the Carriage 12 is turned.

With the frame 1 in the closed position Wing 3 (Fig. 8) is the guide pin 20 of the two-armed lever 18 in the area of the obtuse-angled Bend 30 of the guide slot 21, while the Pin 39 of the steering arm 37 in the area of the fixed Frame 1 facing end of the cam slot 25 am frame-side abutment 23 is located, as well 8 can be seen.

Due to the length dimension of the extension arm 10 between its axle pin 11 and its bearing pin 14 and the already explained operative connection of the two-armed lever 18 and the steering arm 37 via the coupling curve connection 22/40, during the parallel parking movement of the wing 3 from the position according to FIG. 8 in the position according to FIG. 13 controls a forced movement of the lever arm 18b, during which the guide pin 20 is longitudinally displaced within the wing-side guide slot 21. The course of this forced movement can easily be traced on the basis of the successive movement phases of the fitting shown in FIGS. 8 to 13 for the exemplary embodiment shown. In this case, the sash 3 shifts during its shut-off movement which runs essentially transversely to the plane of the fixed frame 1 along a curve 42 which is determined in FIGS. 8 to 13 by the markings 42 ⁸ , 42 ⁹ ... 42 ¹² , 42 ¹³ .

As long as the guide pin 20 of the lever arm 18b in wing-side guide slot 21, the lead bend 27 in front of Has not yet reached latching seat 26, the two-armed Lever 18 in its spreading movement relative to the extension arm 10 guided so that the pin 39 of the steering arm 37 practically always near the end facing the fixed frame of the cam slot 25 in the frame-side abutment 23 remains (see FIGS. 8 to 12). So in the meantime it is Wing 3 through the steering arm 37 so relative to the fixed Frame 1 fixes that it is against horizontal displacement safe from the area of the through opening is held.

Only when the guide pin 20 in the guide slot 21 on the the locking receptacle 26 upstream leading arc 27 is the two-armed lever 18 around the bearing pin 19 on the extension arm 10 gradually pivoted so that with the mediation of Coupling curve connection 22/40 of the pins 39 of the steering arm 37 from the area facing the fixed frame 1 End of the cam slot 25 in the area of Inlet opening 24 of the frame-side abutment 23 arrives and can thus detach from the frame-side abutment 23. At this moment, however, the guide pin is already 20 on the lever arm 18b of the two-armed lever 18 in the latching receptacle 26 entered on wing 3 and stands in front of them Edge 28 which is at an acute angle to the wing plane arrests the locking device 17 in positive engagement supports the extension arm 10 on the wing 3 or on the latter Bearing block 15 against turning back around its bearing pin 14 from. It is then the parallel storage position of the wing 3 relative to the fixed frame 1 or to the on its track 9 movable trolleys 12 permanently locked.

A spring element, for example a leaf spring 31, is on Extension arm 10 is provided in such a way that it or she with a stop 32 on the lever arm 18b of the two-armed lever 18 can work together. It has an arrangement and / or training in which the stop 32 at least occurs at a time when the wing-side Guide pin 21, the locking receptacle 26 in the guide slot 21 has reached. The spring element or the leaf spring 31 can then namely via the stop 32 the two-armed lever 18th or its lever arm 18a convey a movement impulse, which actuates the locking device 17 in the blocking direction and in addition, their engagement position or locking engagement also secures after the pin 39 of the steering arm 37 from the Area of the fixed security intervention 23 has reached.

For practical use, it is advantageous to wing-side guide pin 20 and pin 39 of Steering arm 37 in the pin 22a and 22b of the Support member pair 22 corresponding manner with a Equip jacket roll or sleeve 33, so that a permanent smooth movement of the functional parts concerned can be obtained.

So that the wing 3 with its lower cross member relative to fixed frame 1 not in the parallel storage can get if he from the closed position according to Fig. 1 and 2 in the tilted position according to FIGS. 3 and 4 open between the lower horizontal bar of the Wing 3 and the lower horizontal spar of the fixed Frame 1 special locking devices arranged. This engage in such a way that the lifting movement of the Wing 3 transverse to its plane opposite the fixed Frame 1 on a necessary only for the tilting movement Limit the minimum size. The lower opening devices 7 in this case practically retain that of FIG. 8 corresponding basic position and shift at best by a small amount in the direction of that from FIG. 9 apparent position.

The locking devices can easily be trained get, as with tilt locks for tilt and turn windows and / or doors is known and common.

In particular, Fig. 7 of the drawing can still be seen be that the wing-side bearing blocks 15 for the Extension arms 10 from a tubular extruded profile can be manufactured, the one essentially polygonal, especially rectangular or square Has cross section.

This extruded profile can advantageously be used Manufacture light metal. Points on its lower long side the bearing block 15 has an undercut profiled, channel 33 open on one side, into which a plate 34 can insert the guide slot 21 with the Bend 30, the elbow 27 and the locking receptacle 26 contains. The plate 34 can be within one undercut channel in a predetermined position are clamped, for example, in that in front of the End edges of the same with the undercut areas Press-fit can be provided. In the installation area of plate 34 can the extrusion profile forming the bearing block 15 with a recess, for example a cutout 36, be provided that a sufficiently deep engagement of the Guide pin 20 in the guide slot 21 allows as that 7 shows.

It is also conceivable to screw or plate 34 Set pins against displacement that are in holes of the Engage plate 34 and against the edges of the cutout 36 support.

Fitting for a leaf (3) of doors, windows or the like which, by means of a movement directed transversely of a wall opening plane, can be moved out of a wall opening, for example out of a fixed frame (1), into an at least approximately parallel parking position and, in this parallel parking position, be moved horizontally in a parallel movement to the wall opening plane,

   wherein a releasable locking mechanism (17) is associated with at least one stay arm (10) which is articulated (11, 14) solely for pivoting at one end on a carriage (12) and at the other end on the leaf (3), said carriage being supported on a guide rail (9) parallel to the wall opening,

   wherein the locking mechanism (17) comprises a two-armed lever (18) articulated on the stay arm (10) solely for pivoting in the region between the point of articulation (11) of the stay arm (10) on the carriage (10) and its point of articulation (14) on the leaf (3),

   wherein the two-armed lever (18) engages for pivotal displacement in a guide slot (21) on the leaf (3) by means of a guide pin (20) mounted at the end of the lever arm (18b) facing the leaf (3),

   wherein the guide slot (21) is provided, at its end associated with the parallel parking position of the leaf (3), with a catch recess (26) for the guide pin (20),

   and wherein the guide pin (20) of the locking mechanism (17) is engageable and disengageable relatively to the catch recess (16) by an abutment (23) on the fixed frame (1) as a result of the sliding movement of the leaf (3),

   characterised in that

   the two-armed lever (18) permanently overlaps a control arm (37) by its lever arm (18a) facing the carriage (12),

   in that said control arm (37) is situated (38) with one end axially offset but parallel to the axis of the two-armed lever (18) on the stay arm (10) while its other end is situated freely in front of the carriage (12) and in the path of the movement of the fixed abutment (23),

   in that said control arm (37) between its two ends has a permanent coupling cam connection (22/40) with the lever arm (18a) of the two-armed lever (18) overlapping it,

   in that this coupling cam connection (22/40) can be actuated by that part (41) of the length of the stay arm (10) which is contained between the two pivots (19 and 38) of the two-armed lever (18) and the control arm (37), such part (41) being operative after the style of a double toggle joint,

   in that the control arm (37) carries a catch hook (39) or the like at its free end,

   and in that the catch hook (39) can be brought into and out of operative connection with the fixed abutment (23) by the coupling cam connection (22/40) of the two-armed lever (18) and the control arm (37) on the sliding movement of the leaf (3).
2. A fitting according to claim 1, characterised in that the coupling cam connection (22/40) is formed by a pair of cams (40) and a pair of support members (22).
3. A fitting according to claim 1 or 2, characterised in that the cam pair (40) is situated on the control arm (37) while the support member pair (22) is disposed on the lever arm (18a) of the two-armed lever (18) overlapping the control arm (37).
4. A fitting according to any one of claims 1 to 3, characterised in that the support member pair (22) is formed by rollers or sleeves (22d, 22e) rotatable about pins (22a, 22b).
5. A fitting according to any one of claims 1 to 4, characterised in that the cam pair (40) is formed by contour defining edges (40a, 40b) of the control arm (37), the transverse distance between which increases in the direction away from the bearing point (38) of the control arm (37) on the stay arm (10) towards the free control arm end.
6. A fitting according to any one of claims 1 to 5, characterised in that the cam (40a) of the pair (40) facing the carriage (12) on the control arm (37) is substantially C or j-shaped and relatively flat and long while the cam (40b) remote from the carriage (12) is substantially of flat S or Z-shape and relatively short.
