Abstract

the invention relates to a fitting for mounting between a sash and a fixed frame of a window, door or the like. A fitting (60) for mounting between a leaf (2) and a fixed frame (3) of a window (4), door or the like can be switched into a flip-open state and determines, in the flip-open state, a flip axis (16) about which the leaf (2) can be swung into the flip-open position. A tilt-open limiting device (20) is arranged between the fan beam extending in the transverse direction of the tilt axis (16) and the beam of the fixed frame (3) opposite the fan beam, said tilt-open limiting device having a stop arm and a coupling element supported on the stop arm along the tilt axis (16). The fitting (60) also has a switchable movement stop device (31) and/or a switchable restraining device (61), which are arranged in the installed state between the leaf beam on the tilting axis side, which extends parallel to the tilting axis (16), and the beam of the fixing frame (3) on the tilting axis side, which is opposite the leaf beam. In the pivoted-open state of the fitting (60), the movement-blocking device (31) is switched into a blocking state, in which the movability of the stop element (10) on the fan side relative to the stop element (12) on the fixed frame side and thus of the fan (2) relative to the fixed frame (3) is at least limited in the direction of the pivoting axis (16). The restraint device (61) is switched into a restraint-ready state in a flip-open state of the fitting (60) and when the fan (2) is connected to the fixed frame (3) on the flip-axis side. If the leaf (2) is moved away from the fixed frame (3) perpendicular to the main plane of the window (4), door or the like on the side of the tilting axis in the tilted open state of the fitting (60) and in the restraining-ready state of the restraining device (61), this movement is limited by the restraining element (62) of the restraining device (61) and the restraining arm (63) interacting with said restraining element. A window, door or the like is provided with a fitting (60) of the type described above.

Description

Fitting between a leaf and a fixing frame of a window or door and window or door having such a fitting

Technical Field

The invention relates to a fitting for mounting between a leaf and a fixing frame provided as a component of a window, door or the like,

wherein the fitting can be switched into an open state and in the open state a pivot axis is defined about which the fan can be pivoted into an open position and into a closed position relative to the fixed frame when the fitting is mounted,

Wherein the fitting comprises an opening limiting device which, in the mounted state, is arranged between the fan beam and a beam of the fixed frame opposite the fan beam and which comprises a coupling element arranged on one of the members and a stop arm arranged on the other of the members, which stop arm is rotatable about an axis of rotation,

Wherein, in the open state of the fitting, when the fan is pivoted about the pivot axis, the coupling element of the opening limiting device is guided on the latching arm of the opening limiting device in a radial direction of the rotational axis of the latching arm and is supported longitudinally to the rotational axis of the latching arm,

wherein, in the open state of the fitting, the coupling element of the opening limitation device is arranged close to the axis of rotation of the arresting arm in the closed position of the fan and is arranged away from the axis of rotation in the open position of the fan, and

The opening limitation device has a movement limitation for the coupling element arranged away from the rotational axis, by means of which the coupling element arranged away from the rotational axis is prevented from a movement directed away from the rotational axis of the detent arm in the open position of the fan and thus determines the maximum opening width of the fan.

Furthermore, the invention relates to a window, a door or the like having a fitting of the type described above.

background

A prior art of this type is known from DE 102007017453 a 1. The above-mentioned fitting is fitted between a window, door or the like sash and a fixed frame that are rotatable about a vertical axis, and includes a rotational opening restriction device that restricts the rotational opening angle of the sash. The rotation opening limiting device has a coupling pin which can move on the fan in the folding circumferential direction and a holding arm which is rotatably supported on the fixing frame around a horizontal axis. The coupling pin engages perpendicularly to the fan rotation axis with a guide slot of the retaining arm, which guide slot extends on the retaining arm in the radial direction of the retaining arm rotation axis.

Disclosure of Invention

The object of the invention is to provide a fitting by means of which the tilt-open width of a window, door or similar leaf can be limited and which ensures a high level of security against theft of the tilt-open leaf.

According to the invention, this object is achieved by the fitting according to the invention and by the window, door or the like according to the invention.

The tilt-open limiting device according to the invention comprises a stop arm which is preferably mounted on the fixed frame so as to be rotatable about a rotation axis extending parallel to the tilt axis of the fan, and furthermore comprises a coupling element which is preferably arranged on the fan. The stop arm and the coupling element are preferably mounted on a folding surface of the fixed frame and on a folding surface of the leaf which, in the closed position of the leaf, is opposite the folding surface of the fixed frame. If the fan's axis of roll-over extends horizontally, the fan beam and the fixed frame's beam extend in the vertical direction, a roll-over opening limiting device is provided between the fan beam and the fixed frame's beam. The coupling element and the stop arm of the roll-open limiting device are supported on each other parallel to the roll-over axis.

There is a risk in particular when the door is opened in a flap, for example, that a thief wants to enter a space in which a window, a door or the like is provided. The purpose of the thief is to move the fan away from the fixed frame beyond the flip open width. For this purpose, a force is applied empirically to the flap which is opened in a flip-open manner, not only perpendicular but also parallel to the main plane of the window concerned, the door concerned or the like.

Perpendicular to the associated window, the associated door or the like, the leaf can be loaded by a thief, for example in the region of the tilting axis. By prying up the fan, the thief wants to separate the fan from the fixed frame on the flip axis side. The restraining device according to the invention, which switches into the restraining-ready state when the sash is turned open, resists such a separation of the sash from the fixed frame. If the flap opened is lifted from the fixed frame on the side of the flap axis by a forcible force perpendicular to the associated window, the associated door or the like, the constraint element of the constraint device moves along the constraint arm of the constraint device, which swings about its axis of rotation due to the movement of the flap relative to the fixed frame. As soon as the restraining member of the restraining device becomes active and prevents the restraining element from continuing to move along the restraining arm, the movement of the restraining element along the restraining arm and thus the movement of the fan directed away from the fixed frame is terminated. In the case of a suitable measurement of the length of the restraint arm, the restraint device according to the invention responds with a fan having a spacing from the fixed frame which is too small for a thief to penetrate into the relevant space through the gap between the fan and the fixed frame. The sash, which is forcibly separated from the fixed frame on the side of the overturning axis, remains connected to the fixed frame not only by the restraining means but also by the overturning opening limiting means, which are also anti-theft.

Furthermore, it is possible for the flip-open leaf to open beyond the flip-open width limited by means of the flip-open limiting device in such a way that the connection established between the fixing frame and the leaf by means of the latching arm and the coupling element of the flip-open limiting device is released. The thief will for this purpose strive to eliminate the mutual support of the stop arm of the roll-open limiting device and the coupling element acting along the roll axis of the fan. This can be achieved, for example, by moving the fan relative to the fixed frame longitudinally to the tilting axis by means of a lever-type theft instrument. The movement stop device according to the invention counteracts such a displacement of the fan longitudinally to the flip axis. If the movement-blocking device according to the invention is switched into the blocking state, the mobility of the fan relative to the fixed frame in the longitudinal direction of the tilting axis is at least limited by the blocking elements of the movement-blocking device that interact with one another. In particular, the movement of the fan in the longitudinal direction of the tilting axis is completely prevented by the movement stop device and its stop element.

The fitting according to the invention and the window of the fitting according to the invention, the door provided with the fitting according to the invention or the like are therefore characterized by a high theft protection.

In an advantageous embodiment of the invention, a fitting is provided which is equipped with both the switchable constraining device according to the invention and the switchable movement-blocking device according to the invention, and which thus combines the advantages of both variants of the invention.

The invention also relates to a particularly theft-proof configuration of the fitting according to the invention. The restraining element of the restraining device is configured as a mushroom-head pin that mates with a guide slot having an undercut longitudinal edge on the restraining arm of the restraining device.

in a further development of the fitting for a restraint device according to the invention, a restraint arm is provided which has a guide slot which, depending on the form of the guide slot, has a slot base. The bottom of the slot covers outwards the guide area of the restriction element on the restriction arm of the restriction device. The mutual supporting region of the constraining element and the constraining arm is thereby protected, for example, from contamination and yet is not affected by unauthorized access from the outside.

In a further preferred embodiment of the fitting according to the invention, a securing element of the securing device is also used in order to lock the fan on the fixing frame in the normal case.

The blocking element can advantageously form a structural unit with the restraint arm of the restraint device and can support the restraint arm in a rotatable manner for this purpose.

A particularly load-proof connection of the blocking element to the respective component is achieved if the blocking element can be connected to the respective component independently of the restraint arm. The connection of the restraint arm to the component provided with the locking element is also particularly loadable and therefore theft-proof if the restraint arm is articulated on the locking element and the connection established between the locking element and the restraint arm for this purpose is correspondingly loadable.

In the case of the invention, it is furthermore provided that, in the interest of a particularly high level of protection against theft, a locking element can be screwed to a corresponding component by means of at least one safety bolt, with which locking element the restraint element of the restraint device engages in the locked state of the fitting and on which the restraint arm of the restraint device is rotatably mounted in a preferred configuration of the invention. All customary configurations of safety bolts, for example bolts with a safety insert, loose bolts or one-way bolts, which can be screwed only in the fastening direction by conventional auxiliary tools, can be considered here.

In an advantageous embodiment of the invention, it is provided that the restraining preparation of the restraining device according to the invention for the tilt-open fan is established in such a way that, if the fan makes an unconventional movement relative to the fixing frame on the tilt axis side, the restraining element and/or the restraining arm of the restraining device moves into a restraining preparation position from which the restraining device can respond. The switching of the restraint device into the restraint-ready state can therefore be integrated without problems into the function of a conventional window or door fitting and can be realized, for example, by means of a transmission rod drive.

A flip-open limiting device of the type shown in the present invention can in principle be used as a restraining device according to the invention on the basis of its constructional features. The present configuration takes this into account. The fitting processor is provided with the possibility that one and the same device is sufficient for different applications to reduce its inventory. In addition, fitting parts assembly is unified.

In the case of the configuration of the invention, the restraint-ready state of the restraint device and/or the stop state of the movement stop device is established by switching the fitting from the further functional state into the flip-open state. Accordingly, no separate measures for switching the restraint device in the non-functional state and/or the movement stop device in the non-functional state into the functional state are required.

in a further preferred embodiment of the invention, the movement stop device, which is switched into the stop state, limits or completely prevents the mobility of the fan relative to the fixed frame in both directions, longitudinally to the tilting axis.

According to the invention, the stop state of the moving stop device is brought about by the movement of the stop element on the fan side and/or the stop element on the fixed frame side of the moving stop device into the stop position. The switching of the movement stop device into the stop state is therefore integrated without problems into the function of a conventional window or door fitting. In order to move the stop element on the fan side and/or the stop element on the fixed frame side into the stop position, use can be made in particular of a transmission lever of the fitting, which can also be used for engaging or not engaging the locking element for locking and unlocking the fan on the fixed frame.

The direction of the movement performed by the stop element for switching the movement stop device into the stop state can extend longitudinally to the tilting axis or in a transverse direction to the tilting axis.

The movement stop device according to the invention can be realized in a structurally simple manner if the stop on the fixed frame side is provided as a stop element on the fixed frame side and the counter stop on the fan side assigned to the stop on the fixed frame side is provided as a stop element on the fan side. In the locked state of the movement locking device, the fixed frame-side stop limits or prevents a movement of the sash relative to the fixed frame in the longitudinal direction of the tilting axis by interacting with the fan-side counter-stop.

According to the invention, in addition to the first fixed stop on the fixed frame side and the first counterpart stop on the fan side of the movement stop, a second stop on the fixed frame side and a second counterpart stop on the fan side, which is assigned to the second stop on the fixed frame side and can be moved into the stop position in the longitudinal direction of the tilting axis, are provided. The counterpart stops on the fan side are arranged between the two stops on the fixed frame side in the longitudinal direction of the tilting axis and are switched into the respective stop position by a movement which is moved in the opposite direction in the longitudinal direction of the tilting axis. In the stop position of the two fan-side counter stops, the two fan-side counter stops limit or prevent a movement of the fan in both directions in the longitudinal direction of the tilting axis in interaction with the two fixed frame-side stops. The two frame-side stops and a fan-side counter-stop which can be moved into the stop position in the transverse direction of the tilting axis can interact with each other with the same effect.

in a further preferred embodiment of the invention, both on the fitting according to the invention with a single counterpart stop which can be moved into the locking position longitudinally to the pivot axis and on the fitting according to the invention with two such counterpart stops on the fan side, fitting parts can be provided which serve as counterpart stops on the fan side and can alternatively be used as locking pins.

Storage at the accessory processor is simplified by multiple uses of the same accessory part. The fitting component assembly can be unified. The mechanical device provided for the assembly of the fitting part can be used not only for the assembly of the locking element but also for the assembly of the stop element of the movement stop device according to the invention.

In the case of the simple fitting assembly, the two frame-side stops form a structural unit in the case of the configuration according to the invention. If a fan-side counter stop is provided which can be moved into the stop position in the direction transverse to the tilting axis, the fan-side counter stop can be inserted into the assembly of the fixed-frame-side stops between the fixed-frame-side stops in the direction transverse to the tilting axis. It is thus achieved that the mobility of the fan relative to the fixed frame is effectively limited or prevented in both directions longitudinally to the flip axis.

The fitting according to the invention is characterized by a particularly high level of protection against theft. In the case of this fitting, the mobility of the fan relative to the fixed frame is preferably limited or completely prevented both longitudinally to the tilting axis and transversely to the tilting axis by means of the components of the movement-blocking device.

In a preferred embodiment of the invention, it is provided for this purpose that the stop element on the fan side of the movement stop engages behind the abutment on the fixed frame side and acting in the transverse direction of the tilting axis in the stop state of the movement stop.

In the case of the fitting configuration constructed according to the invention and having a stop pin as a counterpart stop on the fan side, a stop pin having a pin head extending in the radial direction of the pin axis is provided for fixing the fan in the direction transverse to the tilting axis, said stop pin engaging behind a bearing on the fixed frame side with the pin head. In particular, such a locking bolt can alternatively be used as a locking bolt (mushroom head bolt).

If a fan-side counter stop is provided as a fan-side locking element, which counter stop is moved into a locking position in the direction transverse to the tilting axis for switching the movement locking device into the locked state, the movement of the fan-side counter stop must have a component longitudinal to the tilting axis in addition to a component transverse to the tilting axis for establishing a rear engagement with a bearing acting in the direction transverse to the tilting axis.

such a counterpart stop on the fan side corresponds in terms of its kinematics to a circular tongue, which is commonly used as a locking element for locking the fan to the fixed frame. In a preferred embodiment of the invention, the round tongue, which can additionally serve as a locking element, therefore serves as a counterpart stop on the fan side.

In a further development of the invention, in order to simplify the assembly of the fitting parts, the retaining element on the fixed frame side of the movement stop device acting longitudinally to the pivot axis and the bearing for the retaining element on the fan side acting transversely to the pivot axis on the fixed frame side are formed as a structural unit.

such a structural unit can be provided in the form of a conventional locking element for locking the fan. In a preferred embodiment of the invention, such a closure is therefore used in order to limit the mobility of the flap opened relative to the fixed frame both longitudinally and transversely to the flap axis.

in a further development of the invention, the structural unit formed by the retaining element on the fixed frame side and the abutment on the fixed frame side can be screwed to the fixed frame by means of at least one preferably conventional safety bolt, in particular with regard to the security of the fitting according to the invention.

In the case of the inventive configuration, in addition to the movement stop device according to the invention, further protective measures are taken in order to prevent as far as possible an unauthorized movement of the tilt-open fan in the longitudinal direction of the tilt axis. In particular, at least one intermediate element is provided, which extends in the intermediate space existing between the vertical fan beam and the fixing frame opposite the fan beam, in particular in the folding gap, in the longitudinal direction of the tilting axis. The mobility of the fan relative to the fixed frame in the longitudinal direction of the tilting axis is at least limited by such an intermediate element. If intermediate elements are provided on both sides of the fan, longitudinally to the flip axis, undesired movements of the fan are at least partially prevented in both directions, longitudinally to the flip axis.

in the present invention, measures are described which ensure a high level of protection against theft on the flip-open limiting device of the fitting according to the invention.

according to the invention, the coupling element of the tilt-open limiting device is designed as a coupling pin which engages with the mushroom head with a guide slot on the stop arm of the tilt-open limiting device in the longitudinal direction of the tilt axis and engages behind the mushroom head with the longitudinal edge of the guide slot on the stop arm.

In the case of the configuration of the invention, the guide slot provided on the stop arm of the tilt-open limiting device for guiding the coupling pin of the tilt-open limiting device is formed by a guide groove, the groove bottom of which points outside the space of the stop arm. The region where the coupling pin and the stop arm of the tilt-open limiting device support each other is concealed by the closed groove bottom toward the outside of the space. It is therefore difficult to gain at least unauthorized access to the area where the coupling pin and the stop arm of the roll-open restraint support each other.

Preferably, the invention relates to a fitting with a locking function according to the invention. Here, the coupling element of the tilt-open limiting device, for example a mushroom head pin provided as a coupling element, is also used to lock the leaf on the fixing frame. Here, a locking element on a window, door or the like is assigned to the coupling element of the tilt-open limiting device. The stop arm of the tilt-open limiting device is preferably mounted on the closure member in a rotatable manner. The particularly loadable connection of the blocking element to the window, door or the like on which the blocking element is provided is achieved in that the blocking element is connected to the relevant component independently of the latching arm of the tilt-open limiting device. Due to the particularly loadable connection between the blocking element and the component assigned to it, the connection of the blocking arm which is rotatably mounted on the blocking element to the component provided with the blocking element is likewise particularly load-bearing when the blocking arm of the tilt-open limiting device is correspondingly load-bearing rotatably mounted on the blocking element.

Detailed Description

According to fig. 1, the fitting 1 is arranged between a fan 2, which is only schematically shown in fig. 1, and a fixing frame 3, which is likewise only schematically shown, of a window 4.

fitting 1 is a drive rod metal fitting, the fitting part of which on the fan side is seated in the usual manner in a fitting part groove which extends in the fan circumferential direction on the folding surface of fan 2. The fitting part of the fitting 1 on the leaf side is assigned to the fitting part on the fixed frame side, which is arranged on the fold surface of the fixed frame 3 and is connected there to the fixed frame 3.

By rotating the actuating handle 5, the fan-side transmission lever element 6 of the fitting 1 is moved in the fan circumferential direction in a known manner. The fitting part fixed to it is moved by the transmission rod element 6, which is thereby advanced relative to the corresponding fitting part on the fixed frame side. In this way, the fitting 1 can be switched into the rotationally open state shown in fig. 1 and furthermore into the flip-open state and into the locked state.

In the rotated open state of the fitting 1, the handle 5 assumes the rotated position shown in solid lines in fig. 1. The fitting part on the fan side of fitting 1 is positioned relative to the corresponding fitting part on the fixed frame side in such a way that fan 2 is pivoted about a vertical axis of rotation 7 relative to fixed frame 3 and can thereby be moved into a rotationally open or closed position.

This situation results from fig. 2a as shown in the pivoted open state of the fitting 1 in the lower cross-member region of the fan 2 and the fixed frame 3.

The side locking pin 8 on the vertical transmission lever element 6, which is itself guided in the peripheral direction of the leaf on the vertical beam on the opening side of the leaf 2, is arranged outside the side closure 9. The side closure 9 is mounted in a positionally fixed manner on the vertical beam on the opening side of the fixed frame 3. The lower locking pin 10 on the lower transmission rod element 6 is at the level of a through-opening 11 which is provided on the lower closure 12 and through which the lower locking pin 10 can pass in the transverse direction of the main plane of the window 4.

The lower lever element 6 can be moved along the lower sash bar by rotating the actuating handle 5 together with the lower locking pin 10 mounted thereon, while the lower locking element 12 is fixed in place on the lower bar of the fixed frame 3 by means of conventional safety bolts 13 (not shown). The tongue arrangement 13 with the fan-side arrangement part 14 and the fixed frame-side tongue counterpart 15 is not effective in fig. 2a and therefore does not prevent the fan 2 from rotating about the vertical axis of rotation 7.

if the fan 2 is to be tilted open relative to the fixed frame 3 and is to be pivoted about the lower, horizontally extending tilt axis 16 in accordance therewith, the handle 5 can be rotated by 90 ° in the counterclockwise direction from the rotational position shown in solid lines in fig. 1 in order to switch the fitting 1 from the rotationally open state into the tilt-open state. In the folded-open state of the fitting 1, the handle 5, which is shown in dashed lines for this purpose, is directed upwards in fig. 1.

Due to the rotation of the actuating handle 5, the vertical transmission rod element 6 is moved downward from its position according to fig. 2 a. The horizontal transmission rod element 6 is moved to the right from its position according to fig. 2 a. Thus, the side latch pin 8 is farther away from the side latch 9. The lower locking pin 10 enters the right-hand part of the lower locking part 12, which is designed as a double locking part, in fig. 2 a. The round tongue 17 of the round tongue arrangement 13 is pushed out of the arrangement housing 18 of the round tongue arrangement 13 as a result of the movement of the transmission lever and is thereby introduced into the round tongue counterpart 15 on the fixed frame side by a circular movement which has a component in the direction transverse to the tilting axis 16 and a component in the direction longitudinal to the tilting axis 16. Overall, the situation according to fig. 2b results from the situation according to fig. 2a on the lower cross member of the fan 2 and of the fixed frame 3 on the basis of the rotation of the handle 5 from the horizontal position into the upwardly directed position.

As with the side locking pin 8, the lower locking pin 10 is also designed as a mushroom head pin. In the tilted open state of the fitting 1, the lower locking pin 10 enters into a longitudinal slot of the lower locking part 12, which slot extends longitudinally to the tilting axis 16 and is visible schematically in fig. 1, and engages with its mushroom head behind the longitudinal edge of the guide slot on the lower locking part 12. In fig. 2b, to the right, the lower locking pin 10 is directly adjacent to a transverse limitation of the guide slot on the lower locking part 12, which limitation extends in the transverse direction of the pivot axis 16. The round tongue 17 of the round tongue arrangement 13, which enters the round tongue counterpart 15, is arranged with its free end directly adjacent to the lateral limitation of the round tongue counterpart 15, which is located to the left of the round tongue in fig. 2b and extends at the flip axis 16. The free end of the round tongue 17 is spaced slightly further from the lateral limitation of the round tongue counterpart 15 on the right side of said round tongue counterpart. Furthermore, the round tongue 17 pushed out of the device housing 18 engages behind a round tongue fitting 15 which is parallel to the folding surfaces of the fan 2 and the fixing frame 3 which face each other.

the lower latch 12 of the fitting 1 assumes a flip-bearing function for the fan 2 if the fan 2 is pivoted about the flip axis 16 from the closed position into the flip-open position and/or from the flip-open position into the closed position. An intermediate element in the form of a side stop 19 is arranged in the folding space between the vertical beam of the fan 2 and the vertical beam of the fixed frame 3 opposite said vertical beam and ensures the guidance of the fan 2 during its swinging movement about the turning axis 16.

The opening width of the fan 2 swinging into the flip open position is limited by two flip open limiting devices 20 provided away from the flip axis on vertical beams of the fan 2 and the fixed frame 3 extending in the transverse direction of the flip axis 16 (fig. 1).

The structure and the functioning of the flip open limiting means 20 are derived from fig. 5 and 6a to 6 c.

each of the tilt-open limiting devices 20 thus comprises a fixed frame-side stop arm 21 and a fan-side coupling element in the form of a fan-side coupling pin 22 (fig. 6b, 6 c). The latch arm 21 is pivotably supported on the fitting 23. The fitting 23 is screwed with the holding frame 3 on its folding surface and at the same time serves as a closure. The fitting 23 itself is provided with a longitudinal slot 24 (fig. 5), the longitudinal edge of which has an undercut and can engage behind the mushroom head of the coupling pin 22 in the locked state of the fitting 1. The detent arm 21 can be pivoted relative to the fitting 23 about a pivot axis 25 shown in fig. 5 by a chain line. In the mounted position, the axis of rotation 25 extends perpendicularly to the folding plane of the fixing frame 3, in which the fitting 23 and the arresting arm 21 are arranged.

a guide slot 26, which serves for guiding the fan-side coupling pin 22 and has an undercut longitudinal edge, extends in the radial direction of the axis of rotation 25 on the latching arm 21. The longitudinal edges of the guide slot 26 can engage behind the mushroom head of the coupling pin 22 configured as a mushroom head pin. In this case, the shank of the coupling pin 22 passes through the fitting opening 27 of the guide slot 26.

fig. 5 shows the unit formed by the locking arm 21 and the fitting 23 in a view from the side facing the folding plane of the leaf 2, in which the coupling pin 22 is arranged, in the installed position of the tilt-open limiting device 20. In fig. 6a, 6b, 6c, the unit formed by the detent arm 21 and the fitting 23 is shown in a view of the arrangement from the rear facing away from the observer of fig. 5. The groove bottom 30 of the guide slot 26 on the locking arm 21 facing the observer is omitted here for the sake of intuition.

By the orientation according to fig. 6a, the fitting 23 and the stop arm 21 are arranged in the folded space between the leaf 2 and the fixed frame 3 in the closed position of the leaf 2.

Fig. 6b shows the complete flip-open limiting device 20 when the fan 2 is closed and in the rotated open state of the fitting 1. The detent arm 21 assumes its initial position relative to the fitting 23, in which it extends in the vertical direction. The coupling pin 22 arranged on the fan-side transmission lever element 6 is located inside a recess 28 which is enclosed by the detent arm 21 and the fitting 23 and which is open in the transverse direction of the main plane of the window 4. When the fan 2 is rotated about the vertical axis of rotation 7, the coupling pin 22, which moves with the fan 2, enters the cutout 28 or leaves the cutout 28 in a direction transverse to the main plane of the window 4 without any hindrance.

If the fitting 1 is switched from the rotated open position (fig. 1, 2a) into the tilted open position (2b) by rotating the actuating handle 5, the coupling pin 22 on the fan side of the tilt-open limiting device 20 moves downward when the fan 2 is closed, starting from its position shown in solid lines in fig. 6 b. In this case, the coupling pin 22 enters the guide slot 26 in the locking arm 21. In the position occupied at this time, the coupling pin 22 is shown in dashed lines in fig. 6 b. The coupling pin 22 with its mushroom head now engages behind the longitudinal edge of the guide slot 26 on the latching arm 21. The shank of the coupling pin 22 passes through the mating opening 27 of the guide slit 27. Here, the coupling pin 22 of the fitting 1 switched into the flipped open state is also relatively close to the axis of rotation 25 of the latching arm 21 due to the closed state of the leaf 2.

If the fan 2 is now pivoted about the pivot axis 16 into the pivot-open position, the coupling pin 22 moves within the guide slot 26 from the position according to fig. 6b into the position according to fig. 6 c. At the same time, the coupling pin 22 swings the stop arm 21 about the axis of rotation 25 from the vertical initial position into the rotational position according to fig. 6 c. The end wall 29 of the guide slot 26 in the direction of movement of the coupling pin 22 forms a movement limitation for the coupling pin 22 and thus determines the maximum possible flip-open width of the leaf 2.

Fig. 6a, 6b, 6c show the boom 21 in a view on the outside of its space. There, the guide slot 26 of the locking arm 21 is concealed by a groove bottom 30, which is shown transparent for the sake of visibility.

The fan 2, which swings into the flip open position, is largely protected against theft.

On the one hand, the fitting parts shown in detail in fig. 2a, 2b and 2c on the lower cross member of the sash 2 and the fixed frame 3 achieve a particular theft protection. The lower locking pin 10, the lower locking part 12 and the round tongue arrangement 13 as locking pins together form a switchable movement locking device 31 which ensures that the tilt-open leaf 2 can be moved only if necessary slightly in the longitudinal direction of the tilting axis 16 relative to the fixed frame 3. The fan 2 is thereby blocked in both directions longitudinally to the tilting axis 16.

If the leaf 2 is acted upon to the right in fig. 2b, for example by means of a lever-like theft instrument arranged between the leaf 2 and the fixed frame 3, along the pivot axis 16, the lower locking pin 10, which is switched into the locking position in fig. 2b and acts as a locking element on the leaf side of the movement locking device 31, rests against a transverse limitation of the longitudinal slot on the lower closure element 12 opposite the lower locking pin, which itself acts as a locking element on the fixed frame side of the movement locking device 31. The lower lock 12 accordingly forms a fixed-frame-side stop for the lower locking pin 10, which is provided as a counterpart stop on the fan side.

If the fan 2 is forcibly acted upon to the left in fig. 2b, the tongue counterpart 15 as a stop element or stop on the fixed frame side and the tongue 17 of the tongue arrangement 13 as a stop element or a switchable counterpart stop of the movement stop 31 on the fan side interact with one another in a corresponding manner. In the opposite direction, the round tongue counterpart 15 and the round tongue 17 also act as a stop and counter-stop, however with a large clearance in the longitudinal direction of the flip axis 16.

furthermore, the stop 19 on the right in fig. 2b counteracts a lateral displacement of the fan 2 to the right in fig. 2b, and the stop 19 on the left in fig. 2b counteracts a lateral displacement of the fan 2 to the left in fig. 2 b.

In the transverse direction of the tilting axis 16, the lower blocking element 12 forms a support which engages behind the lower blocking pin 10, in particular the mushroom head of the latter. In the same way, the rear engagement of the tab 17 with the mating tab 15 resists the displacement of the fan 2 relative to the fixed frame 3 in the direction transverse to the axis of overturning 16.

the flip open limiting means 20 also contributes to the security of the fan 2. In this respect, it is expedient, on the one hand, if the coupling pin 22 of each tilt-open limiting device 20, which is arranged on the tilt-open leaf 2, engages with its mushroom head behind the longitudinal edge of the guide slot 26 on the corresponding retaining arm 21 on the fixed frame side and thus resists a displacement of the leaf 2 relative to the fixed frame 3 in the longitudinal direction of the tilt axis 16. The connection between the locking arm 21 and the fixing frame 3, which is established by the fitting 23, is particularly loadable in this case, longitudinally to the tilting axis 16.

Thereby preventing the stop arm 21 from being released from the frame 3 by the application of force to the fan 2 along the horizontal flip axis 16. The bending of the detent arm 21 as a result of the application of force to the fan 2 is made difficult at least to a large extent by the solid construction of the detent arm 21. The groove bottoms 30 of the guide slits 26 on the stop arms 21 prevent the mating region of the coupling pin 22 with the guide slits 26 from being reached from outside the space and thus prevent undesired operation of the mating region of the coupling pin 22 with the guide slits 26.

The situation in the locked state of the fitting 1 is shown in fig. 2 c. In fig. 1, a handle 5 is shown (in dashed lines) here downward. The side locking bolt 8 is inserted into the side locking part 9, and the lower locking bolt 10, which engages with its mushroom head behind the longitudinal edge of the longitudinal slot in the lower locking part 12, passes through the through-opening 11 of the lower locking part 12 in the longitudinal direction of the tilting axis from its position according to fig. 2b on account of the rotary actuating handle 5 and is now located on the left side of the through-opening 11 in fig. 2 c. The round tongue arrangement 13 in the example case shown does not assume a locking function. In the locked state of the fitting 1, the coupling pin 22 engages in the longitudinal slot 24 of the fitting 23, which acts as a locking element, on the tilt-open limiting device 20.

the fitting 50 shown in fig. 3 and 4a, 4b, 4c differs from the fitting 1 according to fig. 1 and 2a, 2b, 2c only in that instead of the tongue arrangement 13 of the fitting 1, a counter-moving edge drive unit 51 is provided as part of the movement stop 31. The counter-moving lower stop pin or lower stop pin 52 of the counter-moving edge drive unit 51 serves as a stop element or counter-stop on the fan side and interacts with a pin counterpart 53, which is provided as a stop element or stop on the fixed frame side of the movement stop 31.

In the rotationally open state of the fitting 50, the lower locking pin 52, which is moved in the opposite direction, can pass the pin counterpart 53 in a direction transverse to the main plane of the window 4 (fig. 3, 4 a). In the pivoted-open state of the fitting 50, the lower locking pin 52, which is designed for the reverse movement of the mushroom head pin, is switched into its locking position and is inserted into a longitudinal slot, which extends on the pin fitting 53 longitudinally to the pivot axis 16. In this case, the lower locking pin 52, which is moved in the opposite direction, engages with its mushroom head behind the undercut longitudinal edge of the longitudinal slot on the pin fitting 53 (fig. 4 b). In the locked state of the fitting 50, the lower locking pin 52, which is moved in the opposite direction, engages a double closure 54 arranged between the pin counterparts 53 (fig. 4 c).

Both the pin fitting piece 53 and the double latch 54 serve as a flip-over support for the fan 2 during a flip-over movement of the fan 2 relative to the fixed frame 3 about the flip-over axis 16. If, in the pivoted-open state of the fitting 50 or when the fan 2 is pivoted open, a force directed to the right in fig. 4b is applied to the fan 2 longitudinally to the pivot axis 16, the lower locking pin 52, which is moved in the opposite direction in fig. 4b, comes to rest against the corresponding pin counter-element 53. Accordingly, if the fan 2 is acted upon to the left in fig. 4b, longitudinally to the tilting axis 16, the left pin fitting piece 53 in fig. 4b forms a stop for the lower locking pin 52 assigned to it for the opposite movement.

The fitting 50 also uses lateral intermediate elements or stops 19 which guide the fan 2 laterally as it swings about the turning axis 16 and support the turned-open fan 2 against undesired displacements longitudinal to the turning axis 16. The flip-open limiting device 20 of the fitting 1 according to fig. 1 and 2a to 2c is also part of the fitting 50 according to fig. 3 and 4a, 4b, 4c by way of the same embodiment and functional manner.

the fitting 60 shown in fig. 7 is largely identical in construction and function to the fitting 1 according to fig. 1. The switchable movement stop 31 of the fitting 60 is modified with respect to the fitting 1.

In the case of the fitting 60, no round tongue device 13 of the type shown in fig. 1 is provided. On the lower cross member of the sash 2 and the fixed frame 3 when the window 4 is tilted open, only the lower latching pin 10 of the fitting 60, which serves as a latching element on the sash side, and the lower latch 12, which is assigned to it and serves as a latching element on the fixed frame side, resist lateral movement of the sash 2 relative to the fixed frame 3. In the manner described in detail above, the lower locking pin 10 and the lower lock 12 of the movement stop device 31 of the fitting 60 switched into the stop state jointly prevent an undesired movement of the tilt-open fan 2 to the right in fig. 7, in longitudinal direction to the tilt axis 16.

Instead of the circular tongue device 1 according to fig. 1, a switchable constraining device 61, which is shown very schematically in fig. 7 and in detail in fig. 8, is provided in the case of the fitting 60. The restricting device 61 has the same structure as the tilt-open restricting device 20 fitted to the window 4 away from the tilt axis.

according to fig. 8, the restricting device 61 comprises a fan-side restricting element in the form of a restricting pin 62 and a fixed frame-side restricting arm 63.

The constraining pin 62 is designed as a mushroom head pin and is arranged on the transmission rod element 6 which can be moved along the lower cross member of the sash 2, wherein the constraining pin 62 projects perpendicularly to the folding plane of the lower cross member of the sash towards the constraining arm 63. The restraint arm 63 is mounted so as to be able to rotate about a rotation axis 65 on a support 64, which corresponds to the fitting 23 of the tilt-open limiting device 20. The support 64 is screwed in a positionally fixed manner to the lower cross member of the fixed frame 3 on the folding surface of said fixed frame. For the sake of simplicity, a safety bolt of a conventional design, not shown, is used as the fastening bolt.

on a support 64 screwed to the fixed frame 3, the axis of rotation 65 of the constraint arm 63 extends perpendicularly to the axis of rotation 16 and parallel to the main plane of the window 4. Furthermore, the support 64 serves as a blocking element and is provided for this purpose with a longitudinal slot 66 with undercut longitudinal edges. The undercut longitudinal edges of the longitudinal slot 66 on the support 64 engage behind a pin head 67 into which a pin shaft 68 of the restraining pin 62 expands radially.

Likewise, a guide slot 69 is provided with undercut longitudinal edges, which extends on the restraint arm 63 in the longitudinal direction thereof and which is bounded on its end facing away from the axis of rotation 65 of the restraint arm 63 by a transverse wall 70 serving as a restraint. The groove bottom of the guide slot 69, which is designed as a guide groove, lies opposite the fitting opening 71 of the guide slot 69 and is hidden in fig. 8.

Since the restraining pin 62 is connected to the transmission rod element 6, the restraining means 61 of the fitting 60 can be switched into different functional states by rotating the operating handle 5.

In the closed position of the fan 2 and in the rotated open state of the fitting 60 and accordingly with the handle 5 pointing horizontally to the right, the fan-side constraining pin 62 is in the position shown in solid lines in fig. 8, i.e. in the inlet 72 between the support 64 and the constraining arm 63 of the constraining means 61. Depending on the arrangement of the restraining pins, restraining pins 62 allow fan 2 to rotate about vertical axis of rotation 7.

If, as the fan 2 continues to close, the fitting 60 is switched from its rotated open state into the flipped open state and for this purpose the handle 5 is rotated 90 ° upwards in the counterclockwise direction from its horizontal orientation, the constraining pin 62 is moved to the right in fig. 8 along the constraining arm 63 into a position directly adjacent to its initial position, which is shown in fig. 8 in dashed lines to the right of the constraining pin 62 shown in solid lines. Thus, the restraint pin 62 is inserted into the guide slit 69 on the restraint arm 63. The restricting device 61 of the fitting 60 is thus in the restricting ready state. In the restraining ready state, the restraining means 61 allow the fan 2 to perform a turning movement with respect to the fixed frame 3.

The flip open state of the fitting 60 is configured to the restraint ready state of the restraint device 61. Correspondingly, the lower locking pin 10 is inserted into the lower lock 12 longitudinally to the tumble axis 6. In interaction with the lower lock 12, the lower locking pin 10 inserted therein prevents an undesired displacement of the fan 2 to the right in fig. 7.

The upward displacement of the leaf 2 on the fixing frame 3 perpendicular to the tilting axis 16 is prevented, since the lower locking pin 10 engages with its mushroom head behind the longitudinal edge of the guide slot provided on the lower closure 12 for the lower locking pin 10. The lower locking pin 10, interacting with the lower locking part 12 of the fitting 60 in the tilted open state, effects a support of the leaf 2 on the fixed frame 3 perpendicular to the main plane of the window 4.

In the overturned open condition of the fitting 60 and in the constraint-ready condition of the constraint device 61 associated with said overturned open condition, the constraint pin 62 and the constraint arm 63 of the constraint device 61 occupy a constraint-ready position with respect to each other.

If, in this functional state of the fitting 60 and in particular when the leaf 2 is turned open, a force of considerable magnitude, which is directed outward in an unconventional space, is applied to the leaf 2 perpendicular to the main plane of the window 4 on the side of the axis of rotation, for example in the event of an attempted theft, the support of the leaf 2 on the fixing frame 3, which is effected by the lower locking pin 10 and the lower locking member 12 perpendicularly to the main plane of the window 4, is forcibly cancelled. At the same time, however, the restraint device 61, which is intended to be theft-proof and which is switched for this purpose into the restraint-ready state, is active.

due to the movement of the leaf 2 on the tilting axis side, which is caused by the force of the leaf relative to the fixed frame 3 and is directed outwards in space perpendicular to the main plane of the window 4, the restraining pin 62 of the restraining means 61 moves from its position close to the axis of rotation along the restraining arm 63 with the restraining arm 63 swinging about the axis of rotation 65 until the restraining pin 62 comes to rest against the transverse wall 70 of the guide slot 69. In the position occupied thereby, the restraining pin 62 is shown in dashed lines in fig. 8 to the outside on the right. In interaction with the transverse wall 70 of the constraining arm 63, the constraining pin 62, now arranged away from the axis of rotation, prevents a largely forced opening movement of the sector 2 provided with the constraining pin with respect to the fixed frame 3.

Furthermore, the restriction device 61 provides theft protection in the manner described in detail above for the roll-open limiting device 20.
