Description

The invention relates to a locking device for coupling to at least one drive rod, preferably for coupling at least two drive rods, of a fitting. The locking device has a locking device and a locking device, in particular a locking cylinder. The fitting is in particular the fitting of a, preferably pivoting, wing of a window or a door. In particular, the fitting is part of a rotating sash. Furthermore, the invention relates to a fitting, namely the fitting of a, in particular pivotable, wing of a window or a door with a locking device of the aforementioned type. In addition, the present invention relates to a wing frame arrangement of a door or a window with a fitting of the aforementioned type.

The present invention relates to the technical field of locking and closing devices for windows, known for example from EP 3 650 621 A1 or WO 01/79633 A1 . The present invention preferably lies in the technical field of opening restrictors for windows or doors, in particular with a fall-proof function. With fall-proof windows or doors, there is an opening restriction when the window or door is swung open. The maximum opening width is regulated in different DIN standards. General requirements for windows are set out in DIN 18055 (as of November 2021). The requirements for opening restrictors that can be used for a fall-proof opening are regulated in particular in DIN EN 13126-5:2015-01 (as of November 2021). The opening limiters can be tested, for example, according to the aforementioned DIN EN 13126-5 (as of November 2021). In particular, opening widths of 89 and 100 mm have been established.

In order to ensure that an opening limiter is not released improperly, it is known in practice to provide locking devices that prevent unintentional or unwanted opening beyond the set opening width.

However, crash-resistant windows or doors cannot easily be opened for cleaning, ventilation or maintenance purposes. In particular, cleaning such windows requires a lot of effort, which results in: has that crash-proof windows or doors are rarely cleaned.

The object of the present invention is to avoid or at least substantially reduce the disadvantages of the prior art.

The aforementioned object is achieved by a locking device for coupling to at least one drive rod, preferably for coupling at least two drive rods, of a drive rod fitting, in particular a, preferably pivotable, wing of a window or a door, the locking device having a locking device or a locking device. The locking device can in particular be designed as a locking cylinder. Preferably, the locking device is provided for coupling to at least one drive rod, preferably for coupling at least two drive rods, of a fitting of a rotating sash.

The locking device according to the invention can be actuated by means of a release means in such a way that the locking device can be moved from a locking position into a release position by activation with the release means, the release means being inseparably connected to the locking device in the release position and the release means being separable from the locking device in the locking position is. In particular, a key can be provided as a release means. When designing the locking device as a locking cylinder, it can then be provided in particular that in the release position the key is inseparably or non-removably connected to the locking cylinder, whereas in the locking position the key can be removed from the locking device. The locking device has a coupling element for connection to at least one drive rod, preferably for connecting the drive rods, and a prestressed, in particular spring-loaded, lock for cooperation with the locking device. The locking device itself can have a, in particular rotatable, projection for interacting with the lock. The projection can in particular be designed as a driver or locking lug of the locking device, which is preferably designed as a lock cylinder.

Alternatively or additionally, the coupling element can be designed such that no second drive rod is required. In particular, the coupling element can have a coupling section. The coupling section can be in one piece be formed with the coupling element or firmly connected to the coupling element. From a functional perspective, the coupling section can preferably act as a drive rod. Furthermore, the coupling section can be arranged on the underside of the coupling element and can preferably protrude or protrude from the coupling element.

According to the invention, it is provided that the projection is designed and, in particular in the installed state, arranged in such a way that in the locked position of the locking device, the projection acts on the lock against the preload in such a way that at least one longitudinal movement of the coupling element is caused by striking the lock against a stop of the Coupling element can be blocked and that in the release position the projection can be brought out of engagement with the lock, so that the lock is out of engagement with the stop in the prestressed state, whereby the at least one longitudinal movement of the coupling element can be released.

The longitudinal movement can take place in particular in the longitudinal direction of the drive rod(s). The longitudinal direction of the drive rod(s) can in particular correspond to the longitudinal extent of the drive rod(s) or be aligned along it.

The interaction according to the invention of the components of the locking device has the advantage that a tamper-proof release of the locking device is made possible. This is achieved because the locking device only interacts with the locking device when the release means is inseparably connected to the locking device. In particular, only specialist personnel who are in possession of the release means are therefore permitted to release the locking device.

The locking device can be used for different purposes that require a tamper-proof and/or restricted access locking of the drive rod fitting. The use for opening limiting devices, in particular fall-proof opening limiting devices, is particularly preferred. The locking device can be coupled to the opening limiting device in such a way that in the locking position of the closing device, the opening limiter is coupled to at least one drive rod, preferably the drive rods, and is effective between the frame and the sash. By moving the locking device into the release position a decoupling of the opening limiter can be achieved, in particular so that the window can be swung open.

According to the invention, the possibility is created of "overriding" the locking of the drive rod(s) in a comparatively simple manner, in particular for cleaning, maintenance and/or ventilation purposes.

The fact that the locking device according to the invention is designed in such a way that the release means cannot be separated from the locking device in the release position ensures further protection against incorrect operation. It can be avoided that by removing the release means the window or door remains in the swung-open state while the release means is used to open further windows. In particular, it can be ensured that the locking device is always released in the presence of the operating personnel who are in possession of the release means.

The coupling element can in particular be connected to a drive rod at each of its two front end regions. The coupling element can therefore be viewed as an interrupting element of the drive rod fitting and/or the drive rods. The interruption of the connecting rod fitting and/or the connecting rods makes it possible for the connecting rod fitting and/or the two connecting rods to only interact with one another in the specified manner. It can thus be provided that a coupling between the coupling element and the at least one drive rod, preferably the drive rods, is only made possible in the release state of the locking device, with limited interaction of the drive rod fitting and/or the drive rods being present in the locked position of the locking device.

The locking device can in particular be embedded in the wing profile or arranged in the wing profile, wherein the locking device and in particular the coupling element can be arranged in the drive rod channel of the profile. Ultimately, a locking function of a fitting stroke can be effected by the locking device, which can be canceled by appropriate release via the locking device, so that the fitting stroke can be released. In particular, in the release position, the opening limiter is decoupled from the sash, so that the window or door can be opened completely.

The release means, in particular the key, cannot be separated from the locking device in the release state, since the components installed in the sash rebate preferably block rotation of the projection in this position.

According to the invention, it is particularly understood that a longitudinal displacement of the coupling element is possible even in the locked position or in the locked state, in particular until the lock abuts the stop. Ultimately, a longitudinal displacement of the coupling element, which would result in the lock having to be moved beyond the stop, is not possible. This option is only granted in the release position. The longitudinal displacement of the coupling element can be made possible by actuation with an actuation means, in particular a handle, for actuating the fitting.

Ultimately, in the locked position, a longitudinal movement of the coupling element is blocked by the lock striking the stop. The blockage is removed by moving the locking device into the release position. Ultimately, a certain "leeway" or a certain longitudinal movement of the coupling element and thus also of the lock is permitted in the locked position, but this longitudinal mobility is particularly limited so that a longitudinal movement can be excluded that would lead to the lock would have to be moved beyond the stop.

In principle, of course, the maximum longitudinal mobility or longitudinal movement of the coupling element can also be limited in the release position - however, this limitation is then no longer ensured via the stop, but in particular by further means, preferably via the actuating means for actuating the fitting.

In a particularly preferred embodiment of the present invention, it is provided that the projection is designed and arranged such that in the locking position of the locking device, the projection rests on a coupling region of the lock, preferably directly. In particular, the lock is arranged between the coupling element and the locking device, in particular the projection. The lock can therefore interact directly with the projection in that the projection abuts or borders the coupling area in the locking position. In principle it can also be provided that the projection acts on the coupling area.

Preferably, a receptacle for at least partial arrangement of the lock is provided on the underside of the coupling element. In particular, the coupling element can be designed as a locking plate. The receptacle can be designed in such a way that it faces the wing profile when installed. In particular, the receptacle is designed such that it at least substantially completely accommodates and/or encloses the barrier. Accordingly, the lock is preferably not accessible from the outside and is therefore at least essentially secured against manipulation by the coupling element.

According to the invention, a spring means is assigned to the lock. A leaf spring, for example, can be provided as the spring means. In particular, the spring means is arranged between the underside of the coupling element (facing the receptacle) and the lock. In the installed state, particularly in the locked position, the projection can displace the lock against the spring force, in particular in that the lock, in particular with the coupling area, can abut on the underside of the coupling element.

Furthermore, the spring means can be firmly connected at one end to the lock, so that the coupling element is arranged to be longitudinally displaceable relative to the spring means in the released position of the coupling element - this means that in particular a relative movement of the coupling element to the lock can be made possible. In particular, the spring means is not non-positively or materially connected to the coupling element, but preferably adjoins the underside of the coupling element, so that the lock is prestressed by the spring means.

According to a further preferred embodiment of the inventive concept, a mounting plate of the locking device is provided for, in particular, pivotably mounting the lock. In particular, the mounting plate serves to connect to the rebate of the sash. Alternatively or additionally, it can be provided that the mounting plate is arranged at least partially, preferably completely, in the receptacle of the coupling element in the installed state. In addition, the coupling element can be arranged to be longitudinally displaceable relative to the mounting plate in the released position of the coupling element. Preferably, the lock and thus indirectly also the spring means can be firmly connected to the mounting plate be connected. In particular, it is provided that in the release position a longitudinal movement of the coupling element, but not of the mounting plate and not of the lock, is made possible. Thus, the drive rods or the at least one drive rod in particular do not intervene indirectly in the mobility of the mounting plate and the lock.

In a further preferred embodiment it is provided that the coupling element is arranged and/or can be arranged in a longitudinally displaceable manner relative to the lock and/or the locking device in the released position of the coupling element. The longitudinal displaceability of the coupling element occurs in particular when installed. The lock and the locking device are preferably arranged in a stationary manner on the wing profile, in particular together with the spring means. In the released position, a fitting stroke of the drive rod fitting can be released, the coupling element then serving to couple with the at least one drive rod, preferably the two drive rod ends, and can thus release a stroke.

Preferably, the lock can be pivotably mounted on the mounting plate via a pin and/or a bearing means, in particular wherein the pin or the bearing means is arranged or mounted at least in regions in at least one, preferably in two, bearing opening(s) of the mounting plate. The lock can thus be pivoted relative to the mounting plate, but in particular can be mounted in a stationary manner on the wing profile. The pivotable storage is particularly successful due to the pin or the bearing means.

In addition, it is preferably provided that a first recess and a second recess adjacent to the first recess are formed on the underside of the coupling means facing the locking device. The depressions can in particular be separated from one another via the stop. The stop can be designed as a stop wall. In particular, the second depression can protrude and/or protrude relative to the first depression. Preferably, the spring means abuts the first recess both in the locked state and in the released state. The second recess can be provided for abutting the coupling area of the lock in the released state.

As explained above, the stop between the two recesses prevents the drive rod fitting from being able to move further, particularly in the locked position, and can therefore block a stroke of the fitting. In particular, the second recess can have a starting slope, which can serve to approach the coupling area in the released state.

Preferably, the height of the stop and thus in particular the distance between the two recesses is greater than the thickness of the coupling area of the barrier.

In a further preferred embodiment it is provided that in the blocked position of the coupling element the coupling region of the lock abuts against the first recess of the coupling element and that in the released position of the coupling element the coupling region of the barrier rests on or against the second recess. In particular, the spring means abuts the first recess both in the blocked and in the released position of the coupling element. The spring means thus interacts with the first recess through a corresponding contact or abutment of the spring means against the first recess. The first recess can thus ensure the pretension of the spring means, since the spring means can be supported in particular on the first recess.

Preferably, the locking device is arranged such that in the blocked position of the coupling element, the projection of the locking device, in particular the locking cylinder bit, projects and/or engages in the first recess. The projection can in particular be understood to mean that the projection adjoins and/or faces the first recess.

Alternatively or additionally, it can be provided that in the released position of the coupling element the projection is out of engagement with the first recess.

In particular, the projection cannot be brought into engagement with the recess in the released position of the coupling element, preferably by blocking the projection. The projection can, for example, be arranged adjacent to the first recess and abut the coupling area arranged on the ramp. Blocking the projection leads in particular also means that the release means is inseparably connected to the locking device in this state.

The arrangement of the components of the locking device in the released position is preferably provided in such a way that in the released position the coupling area is arranged on the starting slope or the second recess. The projection can now only be turned slightly until it hits the coupling area. The arrangement of the coupling element and the lock ensures that the projection cannot be pivoted into the area of the starting slope when the coupling element is in the released state.

Furthermore, the present invention relates to a fitting for a, in particular pivotable, wing of a window or door. In particular, the fitting is intended for a rotary sash. The window or door has an opening limiting device of the fitting for limiting the opening of the sash, in particular in a fall-proof manner, preferably when swinging open.

The fitting further comprises a locking device according to one of the aforementioned embodiments. The fitting is intended to be arranged in the rebate between the sash and a sash frame. The locking device is connected to the opening limiting device, in particular indirectly or directly, via at least one drive rod of the fitting connected to the coupling element of the locking device. The connection is preferably made in such a way that the opening limiting device limits the opening width of the sash in the locked position of the closing device. Alternatively or additionally, it can be provided that the connection between the locking device connected to the drive rod and the opening limiting device is designed in such a way that the opening limiting device releases the wing in the release position of the closing device, preferably for unlimited swinging open - that is, in particular without opening limitation.

With regard to preferred embodiments and advantages that result from the fitting according to the invention, reference may be made to the aforementioned argument regarding the locking device, which also applies to the fitting according to the invention, without this needing any further explicit mention. In addition, all features that are described in connection with the fitting can also be applied to the locking device in the same way be transferred without the need for any further explicit explanation.

It is preferably provided that the opening restriction device meets the requirements of DIN EN 13126-5 (as of November 2021).

Preferably, the opening limiting device has at least one scissor arrangement, which preferably has at least one pair of scissors, for limiting the opening of the sash. The scissor arrangement can in particular be designed like opening limiting devices known from the prior art. According to the invention, an opening limiting device “known per se from practice” interacts with the locking device according to the invention. The opening limiting device can thus be “overridden” using the locking device, so that the sash can swing open without limitation.

The present invention also relates to a sash frame assembly of a door or window. The sash frame arrangement has a fitting according to one of the aforementioned embodiments and a rebate. The fitting is arranged in the fold between the sash and the frame of the window or door. In particular, the opening limiting device limits the opening width of the sash in the locked position of the closing device. Alternatively or additionally, it can preferably be provided that the opening limiting device releases the wing in the release position of the closing device, preferably for unlimited swinging - that is, without an opening limitation.

With regard to advantages and preferred embodiments of the sash frame arrangement, reference can also be made to the statements in connection with the locking device according to the invention or with the fitting according to the invention, which can also apply in the same way to the sash frame arrangement according to the invention. In particular, the statements made in connection with the sash frame arrangement can also apply in the same way to the fitting and/or the locking device, without this needing any further explicit mention.

In a particularly preferred embodiment it is provided that the coupling element is arranged in a longitudinally displaceable manner in the rebate on the wing. The lock and preferably the mounting plate can in particular be arranged in a stationary manner on the wing. The coupling element can thus be moved in the fold of the sash according to the release or locking by the locking device.

Preferably, an actuating means designed to actuate the fitting and to cooperate with the locking device, in particular the coupling element, is provided and/or arranged on the wing. The actuating means can in particular be designed as a handle, preferably as a window or door handle. The actuating means can be used in particular to actuate the entire fitting.

In a further, particularly preferred embodiment, it is provided that the actuating means in the locking position of the locking device can only be actuated, in particular rotatable, preferably up to a first position starting from a rest position (in particular the position that is assumed when the window or door is closed). approximately 90°. Accordingly, the actuating means can be rotated, whereby the rest position can differ from the first position in particular by a first rotation, preferably by approximately 90°. The actuating means can be brought beyond the first position into a second position in the release position of the locking device. The second position can differ from the first position by a rotation, preferably a 90° rotation. The pivot point can in particular be arranged in a stationary manner on the wing. In particular, the second position can therefore differ from the rest position by a 180° rotation. Such rotational positions of the actuating means are usually already known to the user. The locking device can ensure that rotation of the actuating means from the first to the second position is only possible for the user if the locking device is correspondingly released by the release means.

Preferably, an anti-operation device is provided, which is designed in such a way that actuation of the actuating means can only be carried out when the window or door is closed. A closed window or a closed door particularly characterizes the so-called closed position. The incorrect operation device is particularly known in the prior art and can ensure that incorrect operation of the window or door, preferably via the actuating means, is excluded outside the closed position. Thus, the actuating means can be transferred from the first to the second position, in particular only in the closed position of the wing, and the corresponding release of the locking device can only be carried out in the closed position.

The Fig. 1 shows an exploded view of parts of a locking device 1. The locking device 1 is intended for coupling at least one, preferably two, drive rod (s) 2, 3. The drive rods 2, 3 belong to a fitting 4, such as in Fig. 9 and 10 is shown. The fitting 4 can in particular be the fitting of a, preferably pivotable, wing of a window or a door.

The locking device 1 has a locking device 5 and a locking device 6. The locking device 5 can have several components, as shown schematically in the Fig. 1 is shown.

In the in Fig. 1 In the exemplary embodiment shown, the locking device 6 is designed as a locking cylinder.

In Fig. 2 is shown schematically that the locking device 6 can be actuated by means of a release means 7. In the exemplary embodiment shown, a key is provided as the release means 7, which can be inserted into the locking cylinder - that is, into the locking device 6. In the exemplary embodiment shown, the locking device 6 can be actuated by means of the release means 7 in such a way that the locking device 6 can be moved from a blocking position into a release position by activation with the release means 7. In the release position, the release means 7 is inseparably connected to the locking device 6 and therefore cannot be removed, the release means 7 being separable from the locking device 6 in the locking position.

The 3A to 8A show different states that can be assumed by the locking device 1 by actuating the release means 7. The figures are divided in such a way that the respective B figures - that is, the 3B to 8B - the respective cuts from the A-figures - that is from the 3A to 8A - represent.

Ultimately, different operations are displayed via the release means 7.

The Fig. 3A shows a first state that corresponds to the locked position. In Fig. 4B The locking position is still shown, but some longitudinally movable components are omitted from the illustration Fig. 3B been moved slightly. This longitudinal displacement was carried out by a stroke of the locking device 5, in particular triggered by actuation of an actuating means for actuating the fitting 4. Also the Fig. 5B continues to show the locked position.

In the 6A to 8A and the corresponding sectional views of the 6B to 8B Different states of the release position are shown. In the release position, the release means 7 is inseparably connected to the locking device 6.

In Fig. 1 it is shown that the locking device 5 has a coupling element 8. Fig. 1 shows the outside of the coupling element 8, whereas the Fig. 11 represents the inside or underside of the coupling element 8.

In Fig. 1 It is further shown that the coupling element 8 is intended for connection to the drive rods 2, 3.

Fig. 12 shows a further embodiment of the locking device 1. In this embodiment, the coupling element 8 is only coupled to a drive rod 3. Furthermore, the coupling element 8 has a coupling section 29, which can function functionally as a drive rod and is in particular connected to the drive rod fitting 4 and/or a gear.

The coupling section 29 can be arranged on the underside 16 of the coupling element 8. In addition, the coupling section 29 can be formed in one piece with the coupling element 8 or can be firmly connected to the coupling element 8. The coupling section can protrude or protrude relative to the coupling element 8.

The locking device 5 also includes a prestressed lock 9. The lock 9 is in particular spring-loaded. The lock 9 can also be designed to cooperate with the locking device 6.

Fig. 1 shows that the locking device 6 has a projection 10. In the exemplary embodiment shown, the projection 10 is designed as a driver or locking lug. The projection 10 is intended and designed to cooperate with the lock 9. Such an interaction between the lock 9 and the projection 10 of the locking device 6 is in the 3A to 8A or in the 3B to 8B shown. Different states of interaction between projection 10 and lock 9 are shown in these illustrations.

Furthermore, they show 3B to 8B that the projection 10 is rotatable, the projection 10 being rotatably mounted on the locking device 6. The locking device 6 can be arranged in particular in a stationary manner on the wing or on the wing profile 28, as shown schematically Fig. 2 shows, wherein a rotation of the projection 10 can be effected by actuation, in particular rotation, of the release means 7. Ultimately, a movement of the release means 7 can cause a movement of the projection 10, provided a corresponding release has occurred.

The projection 10 is designed in such a way and, when installed, is arranged in such a way that in the locked position of the locking device 6, the projection 10 fixes the lock 9 against the preload in such a way that at least one longitudinal movement of the coupling element 8, which is carried out in particular in the longitudinal direction of the coupling element, is carried out The lock 9 can be blocked against a stop 11.

Such a striking of the lock 9 on the stop 11 is particularly in the Fig. 5B shown. The Fig. 5B clarifies that compared to the Fig. 3B a certain "leeway" or a certain longitudinal movement of the coupling element 8 and thus also of the lock 9 can be permitted in the locking position. However, this movement is blocked or limited by the stop 9 striking the stop 11, as shown Fig. 5A becomes apparent. Fig. 4B shows the transition state between the rest position, which is in Fig. 3B is shown, and the "blocked position of the coupling element 8" in the locked position Fig. 5B .

Furthermore, the projection 10 is designed in such a way and arranged in the installed state in such a way that in the release position of the locking device 5, the projection 10 can be brought out of engagement with the lock 9, so that the lock 9 is in the prestressed state State is out of engagement with the stop 11, whereby the at least one longitudinal movement of the coupling element 8 can be released.

This release of the longitudinal movement of the coupling element 8 is in the 6B to 8B shown. The Fig. 6A clarified compared to the Fig. 5A that an actuation or release by the release means 7 has taken place. In the state shown, the key 7 has been rotated in the lock cylinder 6, whereby the locking device 1 has been transferred from the locking position to the release position.

The Fig. 6B clarifies this compared to the Fig. 5A that the projection 10 has been rotated by actuation with the release means 7, whereby the projection 10 has come out of engagement with the lock 9. Accordingly, the lock 9 no longer works in the in Fig. 6B illustrated embodiment to the stop 11, which enables a longitudinal movement of the coupling element 8 beyond the blocked position of the coupling element 8. Such a movement is in the Figures 7B and 8B shown. Both those Fig. 7B as well as that Fig. 8B each illustrates a state that is different from that Fig. 6B has carried out a longitudinal movement. In the in the 6B to 8B In the exemplary embodiment shown, the two drive rods 2, 3 of the fitting 4 are coupled to one another via the coupling element 8, so that the “regular” mode of operation can be enabled.

The locking device 1 thus represents an interruption of the drive rod fitting, whereby the interruption can also be used to limit the opening or to couple with an opening limiter or an opening limiting device 12. Such an opening limiting device 12 is shown schematically in the Fig. 10 shown.

Ultimately, it is the case that a certain longitudinal movement of the lock 9 is made possible even in the locked position, but this can be blocked or blocked by striking the lock 9 against the stop 11. In the blocking position, this blockage is removed in that the projection 10 no longer interacts with the lock 9 or no longer abuts the lock 9.

In principle, of course, the maximum longitudinal mobility or longitudinal movement of the coupling element 8 can also be limited in the release position - however, this limitation is then no longer via the stop 11, but rather by further means, in particular via the actuating means for actuating the fitting 4. For example, the actuating means can be transferred into different positions/positions for actuating the fitting 4, the respective transfer into different positions being coupled to a predetermined lifting or longitudinal movement of the coupling element 8 can be, so that the coupling element 8 ultimately cannot be moved “at will” even in the released state.

However, it can be provided that the blocking position, for example, limits or blocks a movement, in particular rotation, of the actuating means for actuating the coupling element 8 or the drive rod fitting. This design can be particularly advantageous if an opening limiting device 12 that can be coupled to the actuating element is provided, which can in particular be designed as a scissor arrangement. By blocking or blocking the actuating element by the locking device 1 in its locked position, a release of the opening limiting device 12 can then be avoided. Alternatively or additionally, it can be provided that the opening limiting device 12 can only be deactivated and/or released in the release position of the locking device 1.

In the exemplary embodiment shown, the projection 10 is designed and arranged in such a way that in the locked position of the locking device 6, the projection 10 rests on a coupling region 13 of the lock 9, preferably directly. Such a concern of the projection 10 on the coupling area 13 is, for example, in the 3B to 5B shown, which represent different states of the coupling element 8 in the locked position.

In Fig. 11 the underside 16 or the inside of the coupling element 8 is shown. Fig. 11 shows that the coupling element 8 has a receptacle 14 on the underside or inside. In Fig. 3B it is shown that the lock 9 can be arranged in the receptacle 14 at least partially in the installed state.

In Fig. 1 it is shown that the lock 9 is assigned a spring means 15. The spring means 15 can be designed as a leaf spring. In the in Fig. 3B In the exemplary embodiment shown, the spring means 15 is arranged between the underside 16 of the coupling element 8 and the lock 9. Ultimately, the spring means 15 act on the underside 16 of the coupling element 8 and on the lock 9 or ensure a preload between these two components.

In the in Fig. 3B Illustrated embodiment is further provided that the spring means 15 with its one end 17, as shown in Fig. 1 is shown, is firmly connected to the lock 9, so that the coupling element 8 is arranged to be relatively movable or longitudinally displaceable relative to the spring means 15, particularly in the released position of the coupling element 8. Such a longitudinal displacement results from the synopsis of the 3B to 8B . Ultimately, the spring means 15 can be arranged in a stationary manner together with the lock 9, wherein the coupling element 8 can be displaced relative to the lock 9 and relative to the spring element 15. The other end 18 of the spring means 15 can adjoin the underside 16 of the coupling element 8 or abut against the underside 16 when installed.

In Fig. 1 a mounting plate 19 is also shown. The mounting plate 19 can be provided for pivotally mounting the lock 9. In particular, the mounting plate 19 can be arranged together with the lock 9 in a stationary manner on the wing or wing profile 28, wherein the coupling element 8 can be arranged to be relatively movable or longitudinally displaceable relative to the mounting plate 19.

The mounting plate 19 can be provided for connection to the fold of the wing or the wing profile 28. The receptacle 14 of the coupling element 8 can also be designed for at least partial arrangement of the mounting plate 19, as shown schematically Fig. 3B emerges. A longitudinally displaceable arrangement of the coupling element 8 relative to the mounting plate 19 results in particular in the release position of the locking device 1.

Accordingly, the coupling element 8 can be arranged and/or can be arranged in a longitudinally displaceable manner relative to the lock 9 and/or locking device 6 in the released position of the coupling element 8.

In Fig. 1 is shown that the lock 9 is pivotally mounted via a pin or a bearing means 20. In particular, the bearing means 20 is arranged in at least one, preferably two, bearing openings 21 in the mounting plate 19. The bearing openings 21 go from the in Fig. 1 exploded view shown. The storage means 20 can thus be guided through an opening 22 in the lock 9 are and also be arranged in bearing openings 21 of the mounting plate 19. This results in a pivotable mounting of the lock 9 on the mounting plate 19.

In Fig. 11 It is shown that the coupling element 8 has a first recess 23 and a second recess 24 adjacent to the first recess on the underside 16 of the coupling element 8 facing the locking device 5 or the locking device 6. The spring means 15 can in particular strike the first recess 23 with its other end 18 in the blocking position. This is schematic in the Fig. 3b shown. In Fig. 11 It is further shown that the second recess 24 is only partially formed on the underside 14, in particular on a web 25.

In Fig. 3B It is shown that the second recess 24, which is formed in particular on the web 25, can protrude relative to the first recess 23. In particular, the first and second recesses 23, 24 are separated from each other via the stop 11, as shown schematically Fig. 11 becomes apparent.

The stop 11 prevents further movement, particularly in the locked position. In the exemplary embodiment shown, the stop 11 is designed as a wall. In addition, the shows Fig. 11 that the second recess 24 can have a starting slope 26.

In addition, from the 3B to 5B shows that the height of the stop 11 is in particular greater than the, preferably maximum, thickness of the barrier 9 and in particular greater than the thickness of the coupling area 13.

In Fig. 3B is shown that in the blocked position of the coupling element 8, the coupling area 13 abuts the first recess 23. For example, in Fig. 7B In the released position of the coupling element 8 shown, the coupling region 13 of the lock 9 can rest on or against the second recess 24. In particular, the spring means 15 can strike the first recess 23, preferably with its other end 18, both in the blocked and in the released position of the coupling element 8. This can be seen in summary from the Fig. 3B and 7B out.

Furthermore, the locking device 6 can be arranged such that in the blocked position of the coupling element 8, the projection 10 of the locking device 6 can protrude into the first recess 23 and/or can engage in it. This is particularly the case 3B to 5B shown. In the released position of the coupling element 8, however, the projection 10 can be brought out of engagement with the first recess 23, as shown schematically in FIGS 6B to 8B shows in which the projection 10 no longer engages and/or protrudes into the first recess 23. In Fig. 8B it is shown that the projection 25 can abut the coupling region 13 arranged on the second recess 24 even in the released position. In Fig. 6B On the other hand, it is shown that in the released position the projection 10 no longer has to abut the coupling area 13 - but can abut, as shown in Fig. 8B is shown.

Fig. 9 shows a fitting 4, which is intended in particular for a pivoting sash of a window or a door, in particular a rotating sash. The fitting 4 has an opening limiting device 12, as shown Fig. 10 becomes apparent. The opening limiting device 12 can have at least one scissor arrangement 27 for limiting the opening of the sash, the scissor arrangement 27 also being made of Fig. 10 emerges.

The opening limiting device 12 is provided between the sash and a sash frame, which is not shown in detail in the figures. The opening limiting device 12 can be connected to the wing profile 28 or at least partially arranged in it.

The locking device 1 is connected to the opening limiting device 12 via at least one drive rod of the fitting 4 connected to the coupling element 8 of the locking device 1, preferably so that the opening limiting device 12 limits the opening width of the sash in the locked position of the closing device 6 and / or that the opening limiting device 12 in the release position of the locking device 6 releases the wing, preferably for unlimited swinging. Such a coupling via the drive rod(s) between the locking device 1 and the opening limiting device 12 is shown schematically on the Fig. 9 out. The Fig. 9 shows that the coupling element 8 can interact at least indirectly with the opening limiting device 12 and thus also with the scissor arrangement 27 via the drive rod(s). Included It can be provided that in the release position the scissors arrangement 27 and the opening limiting device 12 can be "deactivated", whereas in the blocking position of the locking device 1 the opening limiting device 12 can be effective. How such a transfer from the locked position to the released position is achieved has already been described at the beginning.

A sash frame arrangement of a door or a window is not shown in more detail, the sash frame arrangement having a fitting 4 according to one of the aforementioned embodiments and a rebate. The fitting 4 can be arranged in the fold between the sash and the frame of the window or door. In particular, the opening limiting device 12 limits the opening width of the sash in the locked position of the closing device 6. Alternatively or additionally, it can be provided that the opening limiting device 12 can release the wing in the release position of the closing device 6, preferably for unlimited swinging.

The coupling element 8 can be arranged in a longitudinally displaceable manner in the fold on the wing, in particular in the wing profile 28, whereby the limitation of the longitudinal movement of the coupling element 8 in the locked position can be achieved in the aforementioned manner. The mounting plate 19 can be arranged in a stationary manner on the wing, in particular on the wing profile 28.

What is not shown in more detail is that an actuation means, in particular a handle, can be provided. The actuating means can be designed to actuate the fitting 4 and to cooperate with the locking device 1, in particular the coupling element 8, and can preferably be provided on the wing.

By actuating the actuating means in the locking position of the locking device 6, it can be made possible for the actuating means to be actuable, preferably rotatable, starting from a rest position up to a first position - but not beyond the first position into a second position. The actuating means, on the other hand, can be brought, preferably rotatable, beyond the first position into a second position in the release position of the locking device 6. Transferring the actuating means from the first to the second position can in particular cause a longitudinal movement of the coupling element 8 in the fold.

Furthermore, it is not shown in more detail that an incorrect operating device can be provided, which is designed in such a way that actuation of the actuating means can only be carried out when the window or door is closed. This is the so-called closed position of the window or door. Actuation only in the closed position can therefore be ensured by an incorrect operating device.
