Description

The invention relates to an espagnolette fitting for a building closure element, which has at least one on a frame member of the building closure element linearly displaceable drive rod and a fastened to the frame member and the drive rod covering faceplate, wherein the drive rod by means of a locking device relative to the frame member can be fixed. The invention further relates to a building closure element with a drive rod fitting, a method for operating a drive rod fitting and a method for mounting a drive rod fitting.

From the prior art, for example, the publication EP 1 871 964 B1 known. This concerns a burglar-proof window or door arrangement of a house, for example a window or door arrangement comprising at least one pane which is surrounded by a frame, the window or the door comprising: a mechanism for opening and closing the window or the door, and at least one fuse unit, wherein the fuse unit comprises: an actuator, wherein the actuator triggers when a blocking signal is transmitted to the actuator, a locking device capable of shifting between at least two positions, an unlocked position and a locked position , It is provided that the locking device is arranged so that when the actuator is actuated, the actuator causes the locking device is moved from a non-locked position to the locked position in the receiving device and the window or the door is locked to that effect, be opened by using the opening and closing mechanism of the window or the door, and wherein the actuator by means of a battery which is arranged in the fuse unit, is supplied with power.

It is an object of the invention to provide a drive rod fitting for a building closure element, which has advantages over known espagnolette fittings, in particular has a high level of security and versatility, preferably can be retrofitted very easily. This is achieved with a drive rod fitting with the features of claim 1. It is envisaged that the locking device coupled in a locking setting the drive rod directly to the faceplate and fixed with respect to this and releases the drive rod for displacement with respect to the faceplate in a release setting.

The building closure element is present, for example, in the form of a window, a door or the like. It is so far provided for arrangement and attachment in a building recess of a building and formed. The building closure element preferably has a frame and a sash, wherein the frame is provided and designed for stationary arrangement in the building recess, whereas the sash is displaceable relative to the frame, in particular displaceable on the frame. For example, the sash frame is rotatable relative to the frame about a rotation axis. If the building closure element is in the form of a window, then the window can be designed, for example, as a pivotal window or as a turn-tilt window.

The building closure element has the espagnolette fitting, which in turn has at least one drive rod. On the drive rod or on this with another, for example via a Eckumlenkung, operatively connected further drive rod is a locking pin which cooperates in a locking position with a strike plate to keep the building closure element closed. In a release position, however, he releases the building closure element for opening. The drive rod or the further drive rod is present together with the locking pin on one of the frame members, ie either on the frame or on the sash. The strike plate, however, is arranged on the respective other frame element. Thus, if the drive rod or the locking pin is displaceably mounted on the sash frame or at least storable, the strike plate is arranged on the frame and fixed there.

The locking pin is with respect to the frame member to which it is arranged, linearly displaceable and for this purpose mounted on the frame member, namely by means of the drive rod. The striking plate, however, is fixedly arranged on the respective other frame member, in particular rigidly connected thereto. With closed building closure element, so at Arrangement of the sash with respect to the frame in a closed position, the locking pin cooperate with the strike plate, in particular form-fitting manner, for example by engaging behind. This is the case in the locking position of the lock pin. If the locking pin is in the locking position, the sash frame can not be displaced out of the closed position, in particular not in the direction of an open position, in which the building closure element is at least partially open.

The drive rod is linearly displaceable on the frame element of the building closure element storable or stored. The former is to be understood that the drive rod is provided for mounting on the frame member and suitable, in particular as long as the espagnolette fitting is not mounted on the building closure element. After mounting the espagnolette fitting on the building closure element, the drive rod is mounted on the frame element linearly displaceable. Under the frame element is either the sash or the frame, but preferably the former to understand. If, in the context of this description, only the frame element is discussed, the frame element is always meant without the contrary indication, on which the drive rod can be stored or stored.

For storage of the drive rod, the frame element has, for example, a groove in which the drive rod is arranged for storage. The groove can be configured for example as Euronut. For storage of the drive rod to the frame member and also to improve a visual impression of the espagnolette this has the faceplate, which covers the drive rod at least partially, especially after mounting the espagnolette on the building closure element. The faceplate is so far on the side facing away from the frame member of the drive rod. Preferably, the drive rod is held by the faceplate on the frame member. For this purpose, for example, the drive rod is on the one hand on the frame member and on the other hand on the face plate and is linearly displaceable between them. The cuff rail is thus arranged so that it serves to support the drive rod to the frame member or forms part of this storage.

If the drive rod is arranged in the groove, then the face-plate rail can be designed and arranged such that it closes the groove at least partially. The faceplate is preferably arranged parallel to the drive rod. Both the drive rod and the faceplate extend over at least a portion of the longitudinal extent of a spar the frame element, on which they are arranged and displaceably mounted. The faceplate is preferably attached directly to the frame member. For this purpose, at least one fastening element is preferably provided, which acts on the one hand on the faceplate and on the other hand on the frame member. The fastener extends through this example, the drive rod. Preferably, the fastener is in the form of a screw or a bolt.

It has already been discussed above that the drive rod is linearly displaceable and should be stored correspondingly linearly displaceable. However, it may be desirable to secure the drive rod in the locked position to prevent unlocking and subsequent opening of the building closure element. For this purpose, the espagnolette fitting has the locking device which can fix the drive rod with respect to the frame member. In other words, the locking device serves to set the drive rod so that the unlocking, ie the displacement of the locking pin out of the locking position, in particular up to the release position, is prevented, so that the building closure element securely locked and closed. The locking device may for example be part of an actuating handle, by means of which the drive rod is displaceable. In particular, it may be provided here that the actuating handle via a transmission with the drive rod is operatively connected or coupled, wherein the transmission converts a rotational movement of the actuating handle in a linear displacement of the drive rod.

The locking device is now assigned, for example, the operating handle, in particular it includes a lock and / or a button, in particular a push button. By means of the lock and / or by pressing the button, the operating handle can be fixed. Accordingly, in this case, the drive rod can not be displaced by means of the actuating handle, so that this is fixed relative to the frame member. In other words, the drive rod is set only indirectly with respect to the frame member, namely by setting the operating handle.

When attacking directly on the drive rod, for example in the context of a break-in attempt, there is now a comparatively long traction path in order to fix the drive rod. The force acting on the drive rod must first pass through the gear to the operating handle and be initiated by this in the frame member. Due to the present game, for example due to tolerances and / or elastic and / or plastic deformations, the drive rod can correspondingly be displaced linearly to a certain extent, without the locking device acting on it via the actuating handle being able to prevent this.

Alternatively or additionally, it may be provided that the locking device sets the drive rod directly with respect to the frame member. For this purpose, the locking device engages on the one hand directly on the frame element and on the other hand directly on the drive rod, so that they can be fastened directly to each other. Although such an approach has the advantage over the arrangement of the locking device on the operating handle that the traction path is shorter, so that a reliable setting of the drive rod can be achieved.

However, it is necessary to design the frame element in such a way that the locking device can act on it in such a way that the reliable setting of the drive rod is ensured. For this purpose, for example, a reinforcement or the like is arranged in the frame element. In such an embodiment, it is therefore preferably provided to prepare the building closure element or its frame element already on the locking of the drive rod by means of the locking device and to design accordingly stable. Retrofitting the locking device on a conventional frame element, for example, without reinforcement, is therefore not possible.

For this reason, it is provided according to the invention-alternatively or additionally-that the locking device can couple or couple the drive rod directly to the face-plate rail. This means in other words that the locking device engages for fixing the drive rod on the one hand directly to the faceplate and on the other hand directly to the drive rod. The locking device and the release setting can be adjusted on the locking device. In the locking device, the locking device sets the drive rod with respect to the faceplate, namely by coupling the drive rod directly to the faceplate. In the release setting, however, the locking device releases the drive rod for displacement with respect to the faceplate.

This means that the locking device works completely independently of the building closure element and also independent of the operating handle or the transmission. Already with not mounted on the building closure element espagnolette, the locking device may be preferred so far as to fix the drive rod the faceplate can be used. Because the faceplate is in turn connected to the frame member, in particular rigidly secured to the frame member, the drive rod is finally fixed with respect to the frame member in the locking setting of the locking device.

Under the direct coupling of the drive rod with the faceplate by means of the locking device is to be understood that the coupling in particular does not extend beyond the frame member. It is therefore not intended that the locking device couples the drive rod via the frame member with the faceplate. Rather, it attacks both directly on the drive rod as well as directly on the faceplate. Of course, however, it can be provided that the locking device additionally couples the drive rod directly to the frame member, so that a further improved security is achieved. In such a configuration, the locking device engages on the one hand directly on the drive rod and on the other hand both directly on the face plate as well as directly on the frame member to connect the drive rod in the presence of Arretierungseinstellung each directly with the faceplate and the frame member and set with respect to this.

A further embodiment of the invention provides that the locking device comprises a displaceably mounted by means of a bearing locking element which couples the drive rod directly to the face plate in a present for the locking setting the first position and in a present for the release setting the second position the drive rod of the faceplate decoupled. The locking element is part of the locking device and displaceably mounted, namely by means of at least one bearing. The locking element is preferably linearly displaceable. However, it can also be realized a rotatable mounting or the like.

At least the locking element in the first position and the second position can be arranged. The first position is for the lock setting and the second setting is for the clearance setting. In the first position, the locking element engages both directly on the drive rod as well as directly on the face plate to couple them together and set accordingly against each other. In the second position, the locking element releases the drive rod with respect to the faceplate.

The coupling of the drive rod with the faceplate by the locking element is preferably carried out in a form-fitting manner. For example, the locking element engages in the first position in a locking recess of the drive rod and in a locking recess of the faceplate each form-fitting, wherein the locking recess and the locking bolt are configured such that upon engagement of the locking bolt in the locking recess the immediate coupling and accordingly setting the drive rod exists with respect to the faceplate.

The Arretierungsausnehmung the drive rod and the Arretierungsausnehmung the faceplate are preferably each as an edge-closed recess, so have a continuous edge. Alternatively, of course, an open-edge configuration can also be realized. The locking element is preferably in the form of a locking pin. The locking element is preferably made of a rigid material, in particular of the same material as the drive rod.

A preferred further embodiment of the invention provides that the locking element is present as a locking pin and engages in the first position in a locking recess of the drive rod and in a corresponding Arretierungsausnehmung the faceplate and in the second position for decoupling from the drive rod on the side facing away from the faceplate Driving rod is present. The design of the locking element as a locking bolt has already been pointed out above. The locking pin may in principle have any cross section, for example, it is round, elliptical or rectangular in cross section, in particular cuboid or square. In any case, the locking pin as a cylinder, in particular as a straight cylinder, for example, as a straight circular cylinder present. The drive rod and the faceplate each have a locking recess, wherein both locking recesses are adapted to the locking element and / or dimension-adapted, namely such that the locking element fixes the drive rod with respect to the face-plate positively when engaging in the Arretierungsausnehmungen.

For this setting, the locking element is arranged in the first position. On the other hand, if the locking element is in the second position, it should release the displacement of the drive rod and face-plate against one another. For this purpose, it is preferably on the side facing away from the faceplate of the drive rod, so ultimately on the side facing the frame member of the drive rod. Ideally, the locking element is completely on this page, to release the drive rod not only with respect to the faceplate for relocation, but also with respect to the frame member. Even when the locking element is mounted on the frame element, the displaceability of the drive rod with respect to the faceplate and with respect to the frame element is ensured to that extent in the second position.

In a further preferred embodiment of the invention can be provided that a housing of the locking device is attached directly to the faceplate. In or on the housing at least the locking element is displaceably mounted. Preferably, an actuator for displacing the locking element is additionally arranged in the housing. The housing is arranged on the side facing away from the faceplate on the drive rod. For example, the housing has a sliding surface against which the drive rail rests. The sliding surface serves as far as the storage of the drive rod. The housing is attached directly to the faceplate, in particular by means of a fastener. It can also be provided that the housing is fixed on the side facing away from the drive rod of the faceplate on this. Accordingly, the housing is arranged in a rabbet air area of the building closure element, which is present as a cavity when the building closure element is closed between the wing frame and the window frame.

The fastener preferably passes through the drive rod. For this purpose, the drive rod may have a corresponding recess, for example a slot-like recess. Due to the direct attachment of the housing to the faceplate common mounting of the entire espagnolette fitting on the frame member of the building closure element is possible. In other words, this means that the housing is arranged and fastened together with the drive rod and the faceplate on the frame member. Preferably, therefore, the housing of the locking device is attached via the face plate to the frame member, in particular exclusively. Additionally or alternatively, it may of course be provided to achieve an even higher security, that the housing is attached to a directly on the faceplate and the other engages the frame member, in particular after assembly of the espagnolette on the building closure element rests against the frame member, so supported on it, or is attached to the frame member.

A further development of the invention provides that the housing is fastened to the face-plate rail by means of at least one fastening element extending through an oblong hole of the drive rod is. This has already been pointed out above. The direct attachment of the housing to the faceplate has the particular advantage that the housing can be mounted together with the faceplate and more preferably together with the drive rod to the frame member. In addition, the drive rod is reliably displaceably mounted between the housing and the faceplate, wherein the drive rod preferably bears on the one hand on the housing, in particular on the sliding surface of the housing, and on the other hand on the faceplate.

A further particularly preferred embodiment of the invention provides that the locking element by means of an actuator, in particular an electric motor, an electromagnet or a piezoelectric actuator, is displaceable. For the displacement of the locking element, the actuator is provided in this respect, which in principle can be configured arbitrarily. It is particularly preferably in the form of the electric motor, the electromagnet or the piezoactuator. The actuator is in particular designed such that it causes a linear displacement of the locking element. For this purpose, for example, the electric motor has a corresponding gear, for example a rack and pinion gear, which converts the rotational movement of the electric motor into a linear movement. Of course, alternatively, the electric motor may already be present in the form of a linear motor.

In any case, the actuator is an electric actuator, so that the locking element is displaceable using electrical energy. The electrical energy for the operation of the actuator can be provided for example from an energy storage or by means of a permanent power supply. The energy store is preferably in the form of a battery, in particular a rechargeable battery. Alternatively or additionally, a capacitor may be provided, the capacity of which is preferably dimensioned such that the cached electrical energy reliably and regularly sufficient at least for a displacement of the locking element from the first position to the second position and back to the first position. Under the permanent power supply, for example, a permanent connection to a power grid, especially a wired connection to understand. In the case of the energy storage whose charge is preferably transmitted permanently or periodically to a central control.

A further embodiment of the invention may preferably provide that the locking device has at least one status sensor for detecting an opening state of the building closure element and / or at least one position sensor for detecting a position of the drive rod and / or a position of the locking element and / or a vibration sensor for detecting shocks and / or vibrations and / or a handle position sensor for detecting a position of an operating handle of the building closure element and / or a pressure sensor for detecting a compressive force on the locking element and / or a breakage sensor for detecting a breakage of the locking element. In general, the locking device has at least one sensor, which can take a variety of different forms. The sensor is in the form of one of the following configurations: state sensor, position sensor, vibration sensor, grip position sensor, pressure sensor, and fracture sensor. Of course, several or all of the said sensors may be associated with the locking device.

The state sensor is used to detect the opening state of the building closure element, ie the determination of whether the sash is in the closed position or outside the closed position, in particular in the open position, with respect to the window frame. If the sash frame of the building shutter member is selectively rotatable with respect to the frame by more than one axis, for example, in the case of a turn-tilt window, the opening condition detectable by the condition sensor may discriminate, for example, a closed state, a rotation open state, and a tilt open state.

The position sensor, however, serves to detect the position of the drive rod and / or the position of the locking element and insofar the determination of whether the building closure element is locked or unlocked. Preferably, by means of the position sensor additionally or alternatively determined whether the drive rod is present in a position in which a certain functionality of the building closure element is allowed. If the drive rod is in this position, the functionality is permitted, otherwise prevented. The functionality may be, for example, a screed ventilation, in which the building closure element can only be opened by a certain amount, at least not completely. The functionality may also be a tilting of the sash with respect to the frame, which takes place about a tilting axis, which is different from a rotation axis about which the sash frame is otherwise pivoted upon opening of the building closure element.

The vibration sensor is designed to detect shocks and / or vibrations and serves, for example, to detect a break-in attempt. Additionally or alternatively, it can be determined by means of the handle position sensor in which position the actuating handle of the building closure element is located. The operating handle is used to operate the building closure element or the espagnolette fitting, in particular for displacing the drive rod. For this purpose, the actuating handle is preferably operatively connected or coupled to the drive rod via the transmission already mentioned above.

The pressure sensor serves to detect a force acting on the locking element, for example a shearing force. Such a shearing force is caused, for example, by a force acting on a displacement of the drive rod force on them. In particular, if this force exceeds a breaking force of the locking element, it may lead to a deterioration of the integrity of the locking element, namely a breakage of the locking element. Such can be detected by means of the fracture sensor. The sensors mentioned serve a reliable state recognition of the espagnolette fitting and / or the building closure element. In particular, the locking device can provide a signal for a central control unit as a function of measured values of the at least one sensor or the sensors, for example a central control unit of a home control and / or an alarm system.

Finally, it can be provided in the context of a preferred further embodiment of the invention that the locking device has a drive rod drive for linear displacement of the drive rod. The drive rod drive is preferably also arranged in the housing. The drive rod drive engages at least temporarily on the drive rod in order to shift it in a linear direction. The drive rod drive is particularly preferably an electric drive rod drive. The locking device serves so far not only the setting or releasing the drive rod with respect to the faceplate, but also their displacement. Thus, a particularly high degree of integration of the drive rod and high flexibility is realized.

The invention further relates to a building closure element with a drive rod fitting, in particular an espagnolette fitting according to the statements in this description, wherein the espagnolette fitting has at least one on a frame member of the building closure element linearly displaceable mounted drive rod and attached to the frame member and the drive rod covering faceplate has the drive rod by means of a locking device relative to the frame member can be fixed. It is envisaged that the locking device coupled in a locking position, the drive rod directly to the faceplate and fixed with respect to this and releasing the drive rod for displacement with respect to the faceplate in a release setting.

On the advantages of such an embodiment of the building closure element or the espagnolette fitting has already been pointed out. Both the building closure element and the espagnolette can be further developed according to the statements in the context of this description, so that reference is made to this extent.

A further preferred embodiment of the invention provides that the locking device is arranged at least partially in a recess of the frame member. The recess closes, for example, to the groove in which the drive rod is arranged on. In particular, the recess opens into the groove or starts from this. When the locking device is arranged in the recess, the locking device is preferably arranged completely concealed in the frame element. For this purpose, it is covered, for example, by the faceplate. The recess can already be formed in the production of the frame member in this. However, it can also be provided to produce the recess later in the frame member. Particularly preferably, the latter is provided in the case of a retrofit of the espagnolette fitting on the building closure element.

For example, initially the recess is not available. Rather, a different of the inventive drive rod fitting espagnolette fitting is mounted on the frame member or the building closure element. This will be removed from the frame element. Subsequently, the recess is formed in the frame member, for example by milling. Subsequently, it is readily possible to attach the drive rod fitting according to the invention to the frame member. Finally, it is possible with such an approach to exchange the non-inventive espagnolette fitting against a drive rod fitting according to the invention, so that subsequently a reliable locking of the drive rod relative to the faceplate by means of the locking device and correspondingly a reliable setting of the drive rod with respect to the frame member without supporting configuration of the frame member, for example by Provision of a corresponding reinforcement can be implemented.

It may of course also be provided instead of the arrangement of the locking device in the recess. to dispense with the recess and instead to arrange the locking device on the faceplate on its side facing away from its attachment frame member side. In this case, the locking device is closed Building closure element preferably arranged in a Falzluftbereich, which is present between the window frame and the sash.

Also preferred is an embodiment of the invention, in which it is provided that on the frame member an actuating handle is arranged, which is operatively connected via a transmission with the drive rod to the displacement, and / or that the locking means comprises a drive rod drive for linear displacement of the drive rod. For displacement of the drive rod in the linear direction, the operating handle, the drive rod drive or both are present. The actuating handle is mounted on the building closure element or its frame element, for example, rotatably mounted. The operating handle is connected via the transmission with the drive rod in operative connection or is coupled with this via the transmission. The transmission is preferably provided and designed to implement a rotational movement of the actuating handle in a linear displacement of the drive rod. The drive rod drive integrated in the locking device is preferably an electric drive rod drive, which has at least one electric actuator.

A preferred further embodiment of the invention provides that a locking element of the locking setting has a predetermined breaking point, which is arranged in the presence of the locking adjustment between the drive rod and the face-plate, wherein the predetermined breaking point is designed to ensure an emergency opening of the building closure element by means of the actuating handle. By means of the locking device thus a reliable setting of the drive rod is thus realized with respect to the faceplate. At the same time, however, it is ensured that in an emergency, the emergency opening of the building closure element can be performed. For this purpose, however, the displacement of the drive rod from the locking position to the release position is necessary. Such can only be done if the drive rod is displaceable with respect to the faceplate.

For this reason, it is for example provided that a force is applied via the actuating handle, which leads to the breaking of the locking element at the predetermined breaking point. The force required for this purpose is significantly greater than a force occurring during proper use of the building closure element. Preferably, the force leading to the calculation of the locking element can only be applied via the actuating handle if an additional element is arranged on it, for example a handle extension. Alternatively or additionally, it may be provided that the breaking of the locking element is effected at the predetermined breaking point by means of a suitable means, for example when an electrical signal occurs.

Additionally or alternatively, the espagnolette fitting, its housing and / or the building closure element has access to the locking element. The accessibility is realized, for example, by means of an access opening through which a user of the building closure element can engage the locking element, in particular displace it, preferably only from the inside or from an interior of the building. Attacking takes place, for example, directly or indirectly by means of a corresponding tool. It may be arranged, for example on the housing and / or the building closure element, a different from the operating handle control element which is directly coupled to the locking element. By engaging the locking element and / or actuation of the operating element, the locking element can be displaced into the second position, in particular from the first position out into the second position. With the aid of the access possibility, an opening of the building closure element can also be carried out in the event of a currentless condition and / or a defect in the locking device.

The invention also relates to a method for operating a drive rod fitting for a building closure element, in particular a building closure element according to the statements in this description, wherein the espagnolette fitting at least one on a frame element of the building closure element linearly displaceable storable drive rod and a fastened to the frame member and the drive rod covering Stulpschiene has, wherein the drive rod can be fixed by means of a locking device relative to the frame member. It is envisaged that the locking device coupled in a locking setting the drive rod directly to the faceplate and fixed with respect to this and releasing the drive rod for displacement with respect to the faceplate in a release setting, wherein a setting from the Arretierungseinstellung and the release setting is selected and set on the locking device , With regard to possible embodiments of the espagnolette fitting and the method for its operation, reference is again made to the statements in the context of this description.

A particularly preferred embodiment of the invention provides that a pressure force acting on a locking element of the locking device is determined by means of a pressure sensor and an alarm signal is generated when a pressure force threshold is exceeded by the pressure force. The compressive force is for example in the form of a shear force on the locking element which occurs in the attempt to displace the drive rod with respect to the faceplate. This compressive force or shearing force is determined, for example, by means of a pressure sensor arranged in the locking element. If this pressure force exceeds the pressure force threshold, then the alarm signal is generated.

The alarm signal is supplied, for example, a central control of a home control and / or an alarm system. It can be provided that the generation of the alarm signal is only performed when it is additionally determined by means of a handle position sensor for detecting a position of an operating handle of the building closure element that currently no actuation of the operating handle. In this case, it can be concluded that the compressive force is exerted on the drive rod as part of a break-in attempt. With such a configuration, a particularly high security of the espagnolette fitting against burglary attempts is achieved.

In a preferred embodiment of the invention it can be provided that the central control controls the locking device and selects a setting from the release setting and the locking setting and adjusts it to the locking device. For example, the central controller monitors whether at least one occupant of the building is present. If this is the case, it adjusts the release setting on the locking device. If no resident is present, the lock setting is set. It can be provided that the locking element is displaced directly in the activation of the locking device by the central control, namely either in the first position or the second position.

However, it may also be provided that the displacement of the locking element in the first position when setting the locking setting is done immediately, but the delay in the second position when setting the release setting only delayed. For example, it is provided to sense an actuation of the actuating handle and to shift the locking element into the second position only when it is detected on such an actuation, if the central control has previously set the release setting and this is still present. Sensing takes place by means of a suitable sensor, which is arranged, for example, on the operating handle of the building closure element. The sensor may be present as a force sensor, piezo sensor, torque sensor or the like. For example, it detects a torque acting on the actuating handle and / or a force acting on the push rod, which or which causes by engaging the user on the operating handle becomes. With such a procedure, energy consumption of the locking device is significantly reduced, because the displacement of the locking element in the second position corresponding to the release setting only takes place when the building closure element is actually to be opened. The force sensor is provided and designed, for example, for detecting a displacement force acting on the push rod. For this purpose, the force sensor can be connected to the push rod, in particular be arranged on it. Particularly preferred is an embodiment in which the locking element in the direction of one of the positions, in particular in the direction of the first position, is spring-biased. In the respective direction, the displacement of the locking element can be done without the use of the actuator. In the opposite direction, however, the locking element must be displaced by means of the actuator against the spring force. Here, the spring preload is (re) established. For example, the locking device designed such that when closing and / or locking the building closure element, the locking element is automatically shifted to the first position, so that after locking or locking the Arretierungseinstellung is present and the drive rod is reliably fixed.

Finally, the invention relates to a method for mounting an espagnolette fitting on a building closure element, in particular an espagnolette fitting according to the statements in this description, wherein the espagnolette fitting over at least one linearly displaceable on a frame member of the building closure element storable drive rod and a fastened to the frame member and the drive rod covering Stulpschiene has, wherein the drive rod can be fixed by means of a locking device relative to the frame member. It is envisaged that the locking device coupled in a locking setting the drive rod directly to the faceplate and fixed with respect to this and releases the drive rod for displacement with respect to the faceplate in a release setting, the locking device attached to the faceplate fitting removed from the building fastener fitting on the faceplate and together with the drive rod of the face-plate is attached to the frame member of the building closure element.

For possible embodiments of the building closure element or the method for its mounting is again referred to the statements in the context of this description, which can be used in addition.

It is intended to arrange the locking device on the espagnolette fitting and secure, as long as it is located away from the building closure element. It is therefore provided, for example, to arrange the locking device to the espagnolette or the frame element, the locking device on the espagnolette fitting before mounting the espagnolette fitting and attach it to the frame member together with the drive rod and the faceplate. For example, the espagnolette fitting is first mounted on the building closure element or the frame element. In this case, it is removed from the building closure element, the locking device is arranged on the espagnolette fitting and the espagnolette fitting is fastened again to the building closure element. However, it may also be provided to remove a non-inventive espagnolette fitting from the building closure element and to replace it with an espagnolette fitting to which the detent device is attached. In both cases, a simple retrofitting of the locking device is ensured.

The invention will be explained in more detail with reference to the embodiments illustrated in the drawings, without any limitation of the invention. Showing:

FIG. 1

a schematic representation of a portion of a drive rod fitting for a building closure element, as well as

FIG. 2

another schematic representation of the espagnolette fitting.

The FIG. 1 shows a schematic representation of a portion of a drive rod fitting 1 for a building closure element, not shown. The building closure element is present, for example, in the form of a window, a door or the like. The espagnolette fitting 1 has a drive rod 2, which is linearly displaceable. Furthermore, there is a faceplate 3, which covers the drive rod 2 at least partially. The face-plate 3 is usually attached directly to a frame member of the building closure element, namely by means of a screw and / or at least one fastener 4, preferably - as shown here - several fasteners 4. The fasteners 4 are in the embodiment shown here as screws, which with rest their screw head on the faceplate 3 and on the other hand engage in the frame member of the building closure element. The fastener 4 can - if necessary - pass through the drive rod 2. For this purpose, a slot 5 is formed in the drive rod 2, which a displacement of the drive rod 2 in the linear direction despite the punching through the fastener 4 allows. The linear movement of the drive rod 2 is arranged by the double arrow 6.

The espagnolette fitting 1 further comprises a locking device 7, which allows a setting of the drive rod 2 with respect to the frame member. More specifically, the locking device 7 sets in the presence of a locking setting the drive rod with respect to the faceplate 3, namely by the drive rod 2 directly coupled to the faceplate 3. For this purpose, a locking element 8 is provided, which is displaceable according to the double arrow 9 in the linear direction. The locking element 8 is present for example in the form of a locking pin. For displacing the locking element 8, an actuator 10 is provided which, in the exemplary embodiment shown here, is in the form of an electric motor which is coupled or operatively connected to the locking element 8 via a toothed rack 11. The actuator 10 is preferably arranged in a housing 12 of the locking device 7.

The direct coupling of the drive rod 2 with the faceplate 3 takes place by engaging or reaching through the locking element 8 both in or by a Arretierungsausnehmung 13 of the drive rod 2 and in or by a locking recess 14 of the faceplate 3. In particular, it is provided that the locking element engages both in the locking recess 13 and in the locking recess 14 in a first position. In a second position, however, it is preferably outside of both Arretierungsausnehmungen 13 and 14 before. For example, it is completely arranged in the housing 12, so it is on the side facing away from the faceplate 3 of the drive rod 2, in particular completely.

In the housing 12, a control device 15 may be present, which serves to drive the actuator 10. An energy supply of the actuator 10 and the control device 15 can be effected by means of an energy store 16, which has at least one battery 17 in the embodiment shown here. The control device 15 may have at least one sensor. Thus, a state sensor 18 is preferably provided which cooperates with a magnet 9 to determine an opening state of the building closure element. The magnet 19 is arranged on the respective other frame element as the locking device 7. For example, the magnet 19 is located on a frame and the locking device 7 on a sash of the building closure element.

Furthermore, a position sensor 20 may be present, by means of which a position of the drive rod 2 can be detected. With the aid of the position sensor 20, it can be concluded to this extent whether the drive rod 2 is arranged for locking or unlocking the building closure element. In the case of the unlocked building closure element, it can be particularly preferably determined by means of the position sensor 20 whether a rotation opening or a tilting opening of the building closure element (in the case of an embodiment of the building closure element as a tilt-and-turn window) is set. The control device 15 can also have a communication device 21 via which a communication connection, preferably a wireless communication connection, can be established to a remote station. The remote station is for example part of a control unit of a home control or an alarm system. Furthermore, a position sensor 27 may be present, by means of which a position of the locking element 8 can be detected. With the help of the position sensor 27 can be determined whether the locking element 8 has fixed the drive rod correctly.

The FIG. 2 shows a further illustration of the espagnolette fitting 1. It can be seen that the locking device 7 is connected in a form-fitting manner with the face-plate 3 during assembly. For this purpose, the locking device 7 or its housing 12 has form-locking devices 22, in the exemplary embodiment illustrated herein form-fitting projections, which are brought into positive connection with positive locking counter-devices 23 of the face-plate 3 during assembly. The form-fitting counter-devices 23 are formed in the embodiment shown here as form-fitting recesses.

It is particularly preferably provided that the mounting of the locking device 7, that is, the production of the positive connection between the positive-locking device 22 and the positive locking counter device 23 by screwing the locking device 7 relative to the face-plate 3 takes place. This is indicated by the arrows 24.

In addition, indicated is a transmission 25 for mechanical connection of an actuating handle (not shown) to the drive rod 2. The gear 25 has for receiving the actuating handle or to its connection to a handle receptacle 26 in which a portion of the actuating handle can be arranged in a form-fitting manner. The gear 25 serves to convert a rotational movement of the actuating handle into a linear movement of the drive rod 2.

The described espagnolette fitting 1 has the advantage that on the one hand a reliable and secure setting of the drive rod 2 is achieved with respect to the frame member, namely by direct coupling of the drive rod 2 with the faceplate 3. On the other hand, a trouble-free retrofitting of the building closure element with the locking device 7 is made possible.
