The invention relates to a fitting for an at least tiltable and parallel sash of a window having a fixed frame, a door or the like.

• with a locking linkage of the wing which can be operated by means of an actuating member and which extends from the actuating member at least along the lower wing spar adjacent to the tilting bearings,
• wherein the wing on this wing spar is coupled to the fixed frame by means of a fitting belonging to the fitting, which can be released by the locking linkage and which, in its working position, blocks the shut-off movement, and the lower wing spar is released in the unlocked position of the device,
• the device also has an element fastened to the lower cross member of the fixed frame or the like and a member which is displaceable on the lower wing member relative to a cover bracket or a faceplate and which in its working position engages behind an edge of the element,
• the link being designed as a locking member which can be moved into the unlocked position against the resistance of a return spring and is guided on the cover bracket or on the faceplate,
• and wherein the return spring, in particular a helical compression spring, is inserted between the locking member and a wing-fixed edge, surface or the like, and the element is designed as a locking element.

Fittings of this type are already known, for example by DE-A1 30 33 751, in which a locking linkage has locking pins on the underside of the wing, the in the closed position and in the tilted position of the Intervene in the frame-fixed striking plates and the Secure the sash in these positions. Only when through Operation of the operating lever in the locking linkage Switch position "parallel storage position" is moved the locking pins are aligned with the side openings of the striking plate through which the locking pins move the lower end of the wing in the parallel storage position perpendicular to Level of the frame can emerge.

It is a disadvantage that the wing when it comes out of the parallel position in the closing or Readiness for tipping is transferred back by hand, against a break-in without operating the locking rod is not secured because it is not locked and therefore transferred from the outside again to the parallel storage area can be. Only by actively pressing the Closing linkage is the slidable link in the Tilting of the wing in its locked position brought back so that the wing against unwanted Parallel parking is secured.

A fitting can be found in EP 0 119 433 B1, at which is a latching element that is slidably guided on the faceplate by a return spring permanently in its own Locking position is pressed or held in this. In the locked switch position as well as in the toggle switch position of the wing the latch is not through affects the drive rod as long as it is not together with the locking rod beyond the toggle switch position up to in the switch position for moving the wing in Parallel storage is brought. Just moving the Breech linkage or the drive rod from the rocker switch position towards the switch position for the Parallel storage has the result that the latching member out moved out of its locking position and so the lower one Wing end is released to total the wing in its To bring parallel storage.

As soon as the actuator is released, presses Return spring the latch together with the locking rod in his own locking position back. He follows then the transfer of the wing from the Parallel storage in the tilt position, then the lower Automatically locked again at the end of the tilted wing. The namely, the latching element, which is kept constantly under tension, becomes - by sliding along a locking lug a run-up slope of the locking element - against the Return spring moves until it touches the edge of the locking element reaches behind and thus the lower wing end automatically or is automatically fixed in the tilt position.

This "automatic" locking or fixing of the wing proves to be problematic in so far as the wing too can snap into place. Because it can for example, an unwanted locking out of the user a balcony or the like if the door or the window is accidentally moved to the fixed closed position.

The brochure "GU parallel tilting fitting G.U.-966 for doors and Windows made of wood "and EP 0 339 294 B1 is the fitting according to EP-B2 0 119 433. This is supposed to unintentional engagement of the locking member by a additional and to be operated on the lever actuator Lockout protection can be prevented. It will spring-loaded locking element through the locking linkage disengaged and this position of Lock rod through the lockout counter to the Fixed spring force.

An inadequacy lies in the fact that for the Lockout to be operated additional handling is necessary. It also poses the effect of this lockout protection does not automatically one, but it must always be operated consciously by the user become.

It is therefore an object of the invention to the generic Fitting to evolve so that it is a excludes unwanted user lockout, however on the other hand, maximum security when locking of the wing offers.

• daß die Sperr-Vorrichtung ein zweites gegenüber der Stulpschiene verschiebbares Glied aufweist, welches mit der von der Stulpschiene abgedeckten Treibstange über deren gesamten von einer Verschluß-Schaltstellung über eine Kippöffnungs-Schaltstellung bis in eine End-Schaltstellung reichenden Stellweg hinweg formschlüssig bewegbar gekuppelt ist,
• daß das erste gegenüber der Stulpschiene verschiebbare Glied - das Sperrglied - dieser Sperr-Vorrichtung relativ zum Deckwinkel bzw. zur Stulpschiene in seiner gegen den Widerstand der Rückstellfeder entsperrten Stellung mittels Fixierelemente selbsttätig fixierbar ist,

• und daß die Fixierelemente für das erste Glied - das Sperrglied - einerseits mittels des zweiten Gliedes ihrer Fixierposition zustellbar und andererseits durch das rahmenseitige Element aus ihrer Fixierstellung verdrängbar sind.

According to the invention, this object is achieved by

• that the locking device has a second member which is displaceable with respect to the faceplate and which is coupled in a form-fit manner with the drive rod covered by the faceplate over its entire actuating path extending from a closed switching position via a tilt opening switched position to an end switching position,
• that the first displaceable member relative to the faceplate - the locking member - of this locking device can be automatically fixed relative to the cover bracket or to the faceplate in its position unlocked against the resistance of the return spring by means of fixing elements,
• that the fixing elements for the first link - the locking member - the locking device are provided on the one hand in a region of the travel path for the second link which is immediately adjacent to the end switch position and on the other hand are in the assembled state in a section on the lower wing spar which corresponds to the Cross member of the fixed frame or the like. Fixed element is superimposed,
• and that the fixing elements for the first link - the locking member - can be adjusted on the one hand by means of the second link to their fixing position and on the other hand can be displaced from their fixing position by the frame-side element.

A further increase in the security of the lock can be thereby achieve that the second slidable member Locking latch member forms that on the cross bar of the fixed Frame or the like. In one of the closed switch positions Corresponding position of the drive rod in the closed position on fixed frame or the like. lying wing a second element is assigned as a locking bolt element.

A particularly simple embodiment provides that one the fixing elements from one on the displaceable first link - The locking member - attached to one end, and with their free, other end the first link - locking link - in Direction of action of the return spring arranged in advance Spring tab exists, while the other fixing element from a locking guide fixed to the cover bracket or the faceplate is formed, and that in the working position of the first Link - the locking link - the end of the spring tab Locking guide towards the second link of the device at least by the unlocking travel of the first link - the Locking member - towers over while at a distance behind the free end of a locking lug is in the unlocked position of the first link - the locking link - a Abutment of the locking guide behind.

A further simplification results from the fact that the as Fixing element provided locking guide a distance from second link - the locking member - of the device and within this distance range a longitudinal section of the Spring tab is exposed, of this length of the Spring tab an overrun cam as a trigger for the latch in the effective range of the lower cross member of the fixed frame or the like. Fixed first element protrudes.

A particularly simple and resilient design results by the fact that the other fixing element Snap guide from one with his legs on the Cuff rail attached U-shaped part, which of the U-legs and the U-bridge limited space in Longitudinal direction of the faceplate from the spring tab is reached.

To simplify manufacturing, assembly and warehousing too ensure, it is provided that the locking member with the Return spring which forms the one fixing element Spring tab and a guide housing a structural unit forms, on the faceplate covering the drive rod, in particular the corner angle of a corner drive, detachable is set.

To be as secure as possible or secure The wing can still be fixed to the frame provided that in the assembled state on the lower cross member of the fixed frame or the like. Fixed elements each have an approximately C-shaped Have cross section as a bolt engagement, while the most lower link spar located first link - pawl - and the second link has a complementary cross section, e.g. reversely T-shaped or lying H-shaped cross-section to have.

A gentle interaction of the components thereby allowing the spring tab at its free end an angled latch for the second link of the Has device.

To ensure the functionality of the fitting when the Ensuring the wing in the frame provides the invention further before that the spring tab of the first link - the Locking member - at least to the side of the fixed frame or the like. Associated element at its longitudinal edges with Is chamfered.

To ensure the widest possible range of applications for the fitting offer and also different attachment conditions Taking into account, it is still an advantage that all functional parts of the device one for Longitudinal center plane of the faceplate symmetrical design exhibit.

1 to 6 of the drawing each show a balcony or patio door, which in a fixed frame 1 a fixed wing or a fixed door panel 2 and which also has a movable wing 3 Is provided.

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 parallel bring 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 shown 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 to the door panel 2 are possible, between the wing 3 and the fixed frame 1 has a special fitting arrangement, namely a so-called tilt-parallel parking sliding fitting provided, of the or in FIGS. 1 to 6 of For the sake of simplicity, only the actuator 5 on the wing 3 as well as the upper display device 6 and the lower one Display device 7 between wing 3 and fixed Frame 1 are hinted at.

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.

In the upper opening device 6, care must be taken 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 8a at the bottom Crossbar of the fixed frame 1 cooperates.

The actuator 5 drives this - not visible here Locking rod on, which in the locking position A 1 and 2 with fixed in the frame fold 9 Locking elements 10 - as can be seen in Fig. 5 - interacts. Should the wing 3 in the open position 3 and 4 are transferred, that will Actuator 5 in the corresponding switch position B 3 and 4 brought. About the locking linkage the upper opening devices 6 are actuated and cause the wing 3 to be set down from the frame 1. The lower one horizontal end of wing 3 is through - not here visible - devices in this switch position on the frame 1 held.

If the wing 3 from the open position B in the Open position C, here a parallel storage position, transferred by the actuator 5 in the illustrated Embodiment is operated by a further 90 °, too these locks released. The wing 3 can on his lower horizontal end now also turned off and then be moved laterally.

7 is designed as a drive rod fitting 15 Locking rods along all four bars of the (not there shown) led and doing this in the usual Way housed in the fitting rebate. To every corner of the wing 3, a corner drive 16, 16 'is installed. I.e. it are two upper corner deflections 16 'and two lower ones Corner drives 16 are present, which over each other Intermediate pieces 17 are in a geared actuating connection. The actuation of the drive rod fitting 15 takes place via the Control 5 and a movable with its help Transmission 18. This is designed so that it is the Rotary movement of the operating element 5 in a pushing movement of the connecting rod fitting 15 converts. The transmission 18 moving connecting rod engages one at the top and one at the bottom Corner deflection 16 or 16 '. Each of these corner drives 16 or 16 'stands by a horizontal intermediate piece 17 with a further corner deflection 16 or 16 ', in Connection. There are two corner drives 16 and 16 ' again by a vertical intermediate piece 17 and that Gearbox 18 coupled with each other.

The two upper corner drives 16 'of Espagnolette fitting 15 is an upper one Display device 6 assigned to the wing 3 over Fasteners, such as screws, are mounted can and overlaps to frame 1. The motion control of the upper display devices 6 is used as the Espagnolette fitting 15 trained locking fitting causes, with the intermediary of coupling pieces 19, on the upper horizontal leg of each corner drive 16 provided and in the longitudinal direction of the upper wing spar are slidably arranged.

At the corner drives 16, 16 ', the intermediate pieces 17 and the gear 18 are arranged to be longitudinally displaceable Bolt pin 20 arranged by the drive rod fitting 15 can be moved and with the frame fixed Interlocking elements 10 cooperate.

On the lower horizontal legs of the two lower ones Corner drives 16 are devices 21 for fixing the lower horizontal wing section in the tilt-open position attached to the lower cross member of the fixed frame 1 fastened elements 22, 23 cooperate.

The device 21 is, as shown in FIGS. 8 and 9, on the Fixed corner deflection 16 and acts via a first link 25 together with the element 22 designed as a blocking element.

In the locked switch position or locking position 1 and 2 engages firmly with the Drive rod 26 connected, and therefore over their entire Adjustment path forcibly carried second link 27 in the also formed as a locking element 23. The Drive rod 26 is longitudinally displaceable under one that - not shown - fitting groove covering cover angle or one Face plate 28 out.

On the first link 25 - the locking link - of the device 21 is a spring tab 29 fixed, on the Cover bracket or face plate 28 facing the top of the first link 25. On the cover bracket or the faceplate 28 is also a locking guide forming a fixing element 31 provided. It is with legs 32 on the cover bracket or the faceplate 28 attached and as a U-shaped part educated. This locking guide 31 is in that of the U-legs 32 and a U-web 33 connecting them limited free space in the longitudinal direction of the cover angle or the faceplate 28 penetrated by the spring tab 29. The Locking guide 31 is spaced from the first link 25 attached so that there is an exposed length of the Spring tab 29 results. The U-legs 32 form one Contact edge 32 'for angled on the spring tab 29 Lugs 34, and thus limit the end position of the first Link 25 or the spring tab 29.

The first link 25 - the locking member - is namely by a Return spring 35, which in the exemplary embodiment as Helical compression spring is formed in a Locked position representing the end thrust position. The Return spring 35 is supported in a guide housing 36 from. The guide housing 36, the first link - that Locking element 25 -, the return spring 35 and the spring tab 29 form a structural unit on which the hardware groove or the cover rod covering the drive rod 26 or the Face plate 28 is releasably fixed.

As can be seen from FIGS. 8 and 9, the first link 25 projects - The locking member - in the locking position from above and sideways into the element 22 and locks onto this Way, as well as the second link 27 in connection with the Element 23, the wing 3 on the frame 1.

10 and 11 show the device 21 in the toggle switch position of the espagnolette fitting 15. The fixed with the drive rod 26 coupled second link 27 is from the element 23 open on the side. Everyone is the same others - not visible here - from locking pins 20 and Locking elements 10 locks formed in this Position released. The - not shown - wing 3 is in this switching position of the drive rod fitting 15 only over the first link 25 indented in the element 22 - the Locking member - each device 21 with the frame 1 locked. This allows the wing 3 at its upper end can be moved from frame 1 and - through the upper Display devices 6 held - its tilt opening position 3 and 4 take. It is essential 10 and 11 show that the second link 27 in this Switch position not only from the spring tab 29, but also is laterally spaced from the element 23.

If the espagnolette fitting 15 from the switch position 10 and 11 transferred to the end switch position, results 12 - 13 show - that the second link 27 the first link 25 from the element 22 sideways - to left - displaced.

This is because the spring tab 29 with its second Link 27 facing free end 37 in the travel of the second Link 27 is enough. From this is in positive engagement with the Spring tab 29, the first link 25 from the element 22 and against the resistance of the return spring 35 in his Unlock position. The free end 37 of the spring tab 29 has an angled stop tab 38 for this purpose. In this end switch position, the latch 34 from a Detent edge 39 of the detent guide 31 forming abutment kept spaced. While the spring tab 29, as well Fig. 10 shows, in the tilted position by one on it Underside attached cams 40 from the web 33 in the locking guide 31 is spaced, the spring tab 29 in the end switch position on the web 33 almost flat, the catch 34 reaches the height of the catch edge 39.

In this switching position the wing - not shown 3 - opened and moved, so the first link 25 - that Locking element - do not engage element 22. The wing 3 can thus parallel to FIGS. 5 and 6 parked and moved sideways. But then he can also - unsecured - in a tilt opening position according to Fig. 3 and 4 arrive without the risk of an undesirable Locking and thus locking out.

If the espagnolette fitting 15 when parked in parallel or out of the frame 1 wing 3 moved out of its end switch position returned to the toggle switch position, then the locking lug 34 abuts the locking edge 39, such as the Fig. 14 shows. This will make the first link 25 - that Locking element - prevented the end thrust position 10 and 11 to take. Only when the wing 3 transversely to its level on the frame 1 - for example during the closing process from the parallel storage position - moved up, the exposed distance area of the spring tab 29 also contributes the element 22 together and releases the from the latch 34, the Spring tab 29 and the locking guide 31 existing Snap connection on. This happens because Cooperation of the spring tab 29 with the element 22 in Area of the cam cam 40, the spring tab 29 transverse to Cover angle or to the faceplate 28 is moved and so that the detent 34 detaches from the detent edge 39. The first link 25 - the locking member - is then under the action of Return spring 35 in the locking position shown in FIGS. 10 and 11 moved, in which it remains when the Espagnolette fitting in the closed switch position of Fig. 8 and 9 is returned.

It is essential that the interaction of the element 22nd with the spring tab 29 only on the frame 1 applied wing 3 can be achieved. So is a The latching device can only be triggered if the wing 3 from the parallel storage position to the tilt position or the Closed position transferred and at the same time the Espagnolette fitting 15 at least in the rocker switch position brought.

The wing 3 from the end switch position according to Fig. 6 and 7 - without the wing 3 from the frame 1 in parallel was turned off - back to the toggle switch position 3 and 4 transferred, then the element 22 unlocks the fixation caused by the latch 34 and the latch guide 31 immediately. The wing 3 is then automatically on the fixed Frame 1 locked because the first link 25 - that Locking element - under the action of the return spring 35 in the frame-side element 22 engages from above and sideways (Figs. 10 and 11).

16, a second device 21 can also be used be provided on the lower cross member of the wing 3, for example to securely fix a very large one Ensure wing 3. In this case, too Attachment of the device 21 on the cover rail or Face plate 28. Due to the given switching direction or direction of movement 41 of the drive rod 26 must, however second device 21 in the direction of movement of the second Link 27 are attached. It follows from this that the second device 21 not as in FIGS. 8 to 15 shown - is near the wing corner, but in Switching direction or direction of movement 41 more to the center of the wing must be arranged.

The one in the exemplary embodiment according to FIGS. 1 to 6 Wing 3 shown is for releasing the Through opening 4 shifted from left to right, whereby the gear 18 of the connecting rod fitting 15 in the left vertical spar of the wing 3 is attached. For one of wing 3 opening right to left thus results in a mirrored arrangement of all functional parts. The Shift positions of the transmission 18 are retained, however whereby a wing 3 designed in this way opposite to the switching direction or direction of movement 41 directional drive rod movement results. To this different installation conditions must be taken into account the corner drives 16, 16 'and the devices 21 each longitudinally symmetrical.

The first link 25 - locking member - the return spring 35 and the spring tab 29 form together with the Return spring 35 at least partially encompassing and that first link 25 - locking link - leading guide housing 36 a unit on which the drive rod 26 covering Cover angle or on the faceplate 28 of a corner drive 16 is releasably set.

As can be seen in FIG. 17, the element 22 has one approximately C-shaped cross section. The engaging first link 25 - the locking member - also has a complementary, the shape of an inverted T or a lying H having cross-section. The cross section of the first link 25 - the locking member - is with play on the cross section of the element 22 matched that the tilt position according to FIG. 3rd and 4 can be achieved without the relocation of the Wing 3 around a lower horizontal axis through the Intervention locking is prevented.

That formed from the element 23 and the second link 27 Locking is in an analogous manner with engagement play built up. It is an advantage if the Elements 22, 23 are conventional locking elements, which in a variety of embodiments for different profiles of frame systems available are.

It can also be seen in Fig. 17 that the Spring tab 29 on the cover bracket or the faceplate 28 facing side of the first link 25 - the Locking member - is attached.

As shown in Fig. 18, the other fixing element Locking guide 31 formed from a U-shaped part, which with its connected by the U-web 33 U-legs 32 on the Cover bracket or the faceplate 28 is attached. The thereby delimited free space 42 is in the longitudinal direction of the Cover angle or the faceplate 28 of the spring tab 29th penetrated. In the illustrated embodiment, the U-shaped part firmly with the cover bracket or the faceplate 28 connected. However, this connection can be taken for granted designed to be detachable and with suitable fasteners, for example screws, can be achieved by a universal Availability of the corner drive 16 to achieve.

It should also be added that the devices 21 can of course also be used for fittings that allow two different opening positions, the second opening position being different Opening movement is as the parallel parking described of wing 3. For example, the second Open position around the turn-open position of a Act tilt and turn wing.

Finally, it should be pointed out that the Spring tab 29 - as from FIGS. 9, 11, 13 and 15 emerges - at least to the side of her overrun cam 40 on its longitudinal edges 43 still has bevels 44. These act with corresponding bevels 45 on the Longitudinal edges 46 of the lower cross member of the fixed frame 1 arranged element 22 when the wing 3 enters the Frame 1 from the parallel storage position together (Fig. 13 and 15).
