Description

The invention relates to a drive rod fitting for a building locking element, which has at least one drive rod that can be linearly displaced on a frame element of the building locking element and a faceplate that can be attached to the frame element and covers the drive rod, the drive rod being fixable with respect to the frame element by means of a locking device. 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 assembling a drive rod fitting.

From the prior art, for example, is the document EP 1 871 964 B1 known. This relates to 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 having: a mechanism for opening and closing the window or the door, and At least one safety unit, the safety unit comprising: an actuator, the actuator being triggered when a blocking signal is transmitted to the actuator, a blocking device which is able to move between at least two positions, an unlocked position and a blocked position . It is provided that the locking device is arranged in such a way that, when the actuator is actuated, the actuator causes the locking device to be moved from an unlocked position to the locked position in the receiving device and the window or door is locked to the effect that to be opened by using the opening and closing mechanism of the window and the door, respectively, and wherein the actuator is supplied with power by means of a battery which is arranged in the fuse unit. A drive rod fitting is also, for example, from the FR 2 679 953 A1 which discloses the preamble of claim 1 is known.

It is the object of the invention to propose a connecting rod fitting for a building closure element which has advantages over known connecting rod fittings, in particular has a high level of security and is versatile, preferably can be retrofitted particularly easily. This is achieved with a connecting rod fitting with the features of claim 1. It is provided that the locking device couples the drive rod directly to the faceplate in a locking setting and fixes it with respect to this and, in a release setting, releases the drive rod for displacement with respect to the faceplate and that the drive rod fitting is provided and designed to actuate an operating handle of the building locking element sense and only move the locking element into the release position upon detection of such an actuation, if a central control has previously set a release setting.

The building closure element is, for example, in the form of a window, a door or the like. To this extent, it is intended and designed for arrangement and fastening in a building recess of a building. The building closure element preferably has a frame and a sash frame, the frame being provided and designed for stationary arrangement in the building recess, whereas the sash frame is displaceable with respect to the frame, in particular is mounted on the frame in a displaceable manner. For example, the casement can be rotated about an axis of rotation with respect to the window frame. If the building closure element is in the form of a window, the window can be designed, for example, as a turn window or a turn-tilt window.

The building closure element has the connecting rod fitting, which in turn has the at least one connecting rod. On the drive rod or on a further drive rod that is operatively connected to it, for example via a corner deflection, there is a locking pin which, in a locking position, interacts with a locking plate in order to keep the building locking element closed. In a release position, however, it 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 elements, that is to say either on the frame or on the casement. The strike plate, however, is arranged on the respective other frame element. If the drive rod or the locking pin is displaceably mounted on the casement or at least can be mounted, the strike plate is arranged on the frame and fastened there.

The locking pin is linearly displaceable with respect to the frame element on which it is arranged and for this purpose is mounted on the frame element, namely by means of the drive rod. The strike plate, however, is arranged in a stationary manner on the other frame element, in particular rigidly connected to it. When the building closure element is closed, i.e. at Arranging the casement with respect to the window frame in a closed position, the locking pin can interact with the striking plate, in particular in a form-fitting manner, for example by reaching behind. This is the case in the locking position of the locking pin. If the locking pin is in the locking position, the casement cannot be moved 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 can be mounted or mounted in a linearly displaceable manner on the frame element of the building closure element. The former is to be understood as meaning that the drive rod is intended and suitable for mounting on the frame element, in particular as long as the drive rod fitting is not mounted on the building closure element. After the drive rod fitting has been installed on the building closure element, the drive rod is mounted on the frame element so as to be linearly displaceable. The frame element is to be understood as meaning either the casement or the frame, but preferably the former. If only the frame element is dealt with in the context of this description, the frame element on which the drive rod can be or is supported is always meant, unless otherwise indicated.

For mounting the drive rod, the frame element has, for example, a groove in which the drive rod is arranged for mounting. The groove can be designed, for example, as a euro groove. To mount the drive rod on the frame element and also to improve the visual impression of the drive rod fitting, it has the faceplate, which covers the drive rod at least in some areas, especially after the drive rod fitting has been installed on the building closure element. The faceplate is in this respect on the side of the drive rod facing away from the frame element. The drive rod is preferably held on the frame element by the faceplate. For this purpose, for example, the drive rod rests on the one hand on the frame element and on the other hand on the faceplate and can be linearly displaced between these. The faceplate is thus arranged in such a way that it serves to support the drive rod on the frame element or forms part of this support.

If the drive rod is arranged in the groove, the faceplate can be designed and arranged in such a way that it closes the groove at least in some areas. The faceplate is preferably arranged parallel to the drive rod. Both the drive rod and the faceplate each extend over at least part of the longitudinal extension of a spar of the frame element on which they are arranged and mounted displaceably. The faceplate is preferably attached directly to the frame element. For this purpose, at least one fastening element is preferably provided, which engages on the one hand on the faceplate and on the other hand on the frame element. The fastening element extends through, for example, the drive rod. The fastening element is preferably in the form of a screw or a bolt.

It has already been discussed above that the drive rod can be displaced linearly and should be mounted so that it can accordingly be displaced linearly. However, it may be desirable to fix the drive rod in the locking position in order to prevent unlocking and subsequent opening of the building closure element. For this purpose, the drive rod fitting has the locking device which can fix the drive rod with respect to the frame element. In other words, the locking device is used to fix the drive rod in such a way that unlocking, i.e. shifting the locking pin out of the locking position, in particular into the release position, is prevented, so that the building locking element remains securely locked and locked. The locking device can, for example, be part of an actuating handle by means of which the drive rod can be displaced. In particular, it can be provided that the actuating handle is operatively connected or coupled to the drive rod via a gear, the gear converting a rotary movement of the actuating handle into a linear displacement of the drive rod.

The locking device is now assigned, for example, to the actuating handle, in particular it comprises a lock and / or a button, in particular a push button. The operating handle can be fixed by means of the lock and / or by operating the button. Correspondingly, in this case the drive rod cannot be displaced by means of the actuating handle, so that it is also fixed with respect to the frame element. In other words, the drive rod is only fixed indirectly with respect to the frame element, namely by fixing the operating handle.

If the drive rod is attacked directly, for example in the context of a break-in attempt, there is now a comparatively long traction path to fix the drive rod. The force acting on the drive rod must first reach the actuating handle via the transmission and be introduced by this into the frame element. Because of the play present here, for example because of tolerances and / or elastic and / or plastic deformations, the drive rod can accordingly be linearly displaced to a certain extent without the locking device acting from it via the actuating handle being able to prevent this.

As an alternative or in addition to this, it can be provided that the locking device fixes the drive rod directly with respect to the frame element. For this purpose, the locking device acts directly on the one hand on the frame element and on the other hand directly on the drive rod so that they can be fastened directly to one another. Such a procedure has the advantage over the arrangement of the locking device on the actuating handle that the frictional connection path is shorter, so that a reliable fixing 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 drive rod is reliably fixed in place. For this purpose, reinforcement or the like is arranged, for example, in the frame element. In such a configuration, it is therefore preferably provided that the building closure element or its frame element is already prepared for the locking of the drive rod by means of the locking device and designed to be correspondingly stable. Retrofitting the locking device on a conventional frame element, for example without reinforcement, is therefore not possible.

According to the invention it is for this reason - alternatively or additionally - provided that the locking device couples or can couple the drive rod directly to the faceplate. In other words, this means that the locking device for fixing the drive rod acts directly on the faceplate on the one hand and directly on the drive rod on the other hand. The locking setting and the release setting can be set on the locking device. In the locking device, the locking device fixes 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 locking element and also independently of the actuating handle or the transmission. Even when the connecting rod fitting is not mounted on the building closure element, the locking device can in this respect be preferred for fixing the connecting rod the faceplate can be used. Because the faceplate for its part is connected to the frame element, in particular is rigidly attached to the frame element, the drive rod is finally fixed in relation to the frame element in the locking setting of the locking device.

The direct coupling of the drive rod to the faceplate by means of the locking device is understood to mean that the coupling in particular does not run via the frame element. It is therefore precisely not provided that the locking device couples the drive rod to the faceplate via the frame element. Rather, it engages both directly on the drive rod and directly on the faceplate. Of course, however, it can be provided that the locking device also couples the drive rod directly to the frame element so that further improved safety is achieved. In such a configuration, the locking device engages directly on the drive rod on the one hand and directly on the faceplate as well as directly on the frame element on the other hand, in order to connect the drive rod directly to the faceplate and the frame element and fix it with respect to them when the locking setting is present.

Another embodiment of the invention provides that the locking device has a locking element which is movably mounted by means of a bearing and which in a first position for the locking setting directly couples the drive rod to the faceplate and in a second position for the release setting the drive rod from the faceplate decoupled. The locking element is part of the locking device and is mounted displaceably, namely by means of the at least one bearing. The locking element is preferably linearly displaceable. However, a rotatable mounting or the like can also be implemented.

At least the locking element can be arranged in the first position and the second position. The first position is for the detent setting and the second setting is for the release setting. In the first position, the locking element engages both directly on the drive rod and directly on the faceplate in order to couple them with one another and fix them accordingly against one another. In the second position, the locking element releases the drive rod with respect to the faceplate.

The coupling of the drive rod to the faceplate by the locking element is preferably effected in a form-fitting manner. For example, in the first position, the locking element engages in a locking recess in the drive rod and in a locking recess in the faceplate in each case in a form-fitting manner, the locking recess and the locking bolt being designed in such a way that when the locking bolt engages in the locking recess, the direct coupling and, accordingly, the fixing of the drive rod with regard to the faceplate.

The locking recess of the drive rod and the locking recess of the faceplate are each preferably in the form of a closed-edge recess, that is to say have a continuous edge. Alternatively, an open-edged design can of course also be implemented. The locking element is preferably in the form of a locking bolt. 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 bolt and in the first position engages in a locking recess in the drive rod and in a corresponding locking recess in the faceplate and in the second position for decoupling from the drive rod on the side facing away from the faceplate Drive rod is present. The design of the locking element as a locking bolt has already been pointed out above. The locking bolt can basically 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 bolt can be present as a cylinder, in particular as a straight cylinder, for example as a straight circular cylinder. The drive rod and the faceplate each have a locking recess, with both locking recesses being adapted in shape and / or dimensions to the locking element, namely in such a way that the locking element fixes the drive rod in a form-fitting manner with respect to the faceplate when it engages the locking recesses.

For this setting, the locking element is arranged in the first position. If, on the other hand, the locking element is in the second position, it should enable the drive rod and faceplate to move relative to one another. For this purpose, it is preferably present on the side of the drive rod facing away from the faceplate, that is to say ultimately on the side of the drive rod facing the frame element. Ideally, the locking element lies completely on this page in order to release the drive rod for relocation not only with regard to the faceplate, but also with regard to the frame element. 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 in the second position.

In the context of a further preferred embodiment of the invention it can be provided that a housing of the locking device is attached directly to the faceplate. At least the locking element is displaceably mounted in or on the housing. An actuator for displacing the locking element is preferably also arranged in the housing. The housing is arranged on the drive rod on the side facing away from the faceplate. For example, the housing has a sliding surface on which the drive rail rests. The sliding surface serves to support the drive rod. The housing is attached directly to the faceplate, in particular by means of a fastening element. It can also be provided that the housing is attached to the faceplate on the side of the faceplate facing away from the drive rod. Correspondingly, the housing is arranged in a rebate area of the building closure element which, when the building closure element is closed, is present as a cavity between the casement and the frame.

The fastening element preferably extends through the drive rod. For this purpose, the drive rod can have a corresponding recess, for example a slot-like recess. Due to the direct attachment of the housing to the faceplate, joint assembly of the entire drive rod fitting on the frame element of the building closure element is possible. In other words, this means that the housing is arranged and fastened to the frame element together with the drive rod and the faceplate. The housing of the locking device is therefore preferably fastened to the frame element via the faceplate, in particular exclusively. Additionally or alternatively, it can of course be provided to achieve even greater security that the housing is on the one hand attached directly to the faceplate and on the other hand engages the frame element, in particular rests against the frame element after the espagnolette fitting has been installed on the building closure element supported on him, or attached to the frame element.

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

Another particularly preferred embodiment of the invention provides that the locking element can be displaced by means of an actuator, in particular an electric motor, an electromagnet or a piezo actuator. In order to move the locking element, the actuator is provided, which in principle can be designed as desired. It is particularly preferably in the form of the electric motor, the electromagnet or the piezo actuator. The actuator is designed in particular in such a way that it effects 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 rotary movement of the electric motor into a linear movement. Of course, the electric motor itself can alternatively already be in the form of a linear motor.

In any case, the actuator is an electrical actuator, so that the locking element can be displaced using electrical energy. The electrical energy for operating the actuator can be provided, for example, from an energy store 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 can be provided, the capacity of which is preferably dimensioned such that the electrical energy temporarily stored in it is reliably and regularly sufficient at least to move the locking element from the first position to the second position and back again to the first position. The permanent power supply is to be understood as meaning, for example, a permanent connection to a power grid, in particular a wired connection. In the case of the energy store, its charge status is preferably transmitted permanently or periodically to a central controller.

A further embodiment of the invention can preferably provide that the locking device has at least one state sensor for detecting an open state of the building locking 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 grip position sensor for detecting a position of an actuating handle of the building locking element and / or a pressure sensor for detecting a pressure force on the locking element and / or a break sensor for detecting a break in the locking element. In general, the locking device has at least one sensor which can assume a large number of different forms. The sensor is available in the form of one of the following configurations: condition sensor, position sensor, shock sensor, grip position sensor, pressure sensor and breakage sensor. Of course, several or all of the sensors mentioned can be assigned to the locking device.

The state sensor is used to detect the opening state of the building closure element, i.e. to determine whether the casement is in the closed position with respect to the window frame or outside the closed position, in particular in the open position. If the sash of the building closure element is optionally rotatable or pivotable about more than one axis with respect to the window frame, for example in the case of a tilt and turn window, the opening state that can be detected by the state sensor can, for example, distinguish between a closed state, a rotary open state and a tilt open state.

The position sensor, on the other hand, is used to detect the position of the drive rod and / or the position of the locking element and, to that extent, to determine whether the building locking element is locked or unlocked. Preferably, the position sensor can additionally or alternatively determine whether the drive rod is in a position in which a certain functionality of the building locking element is permitted. If the connecting rod is in this position, the functionality is permitted, otherwise it is prevented. The functionality can be, for example, a gap ventilation in which the building closure element can only be opened to a certain extent, at least not completely. The functionality can also be a tilting of the casement with respect to the window frame, which takes place around a tilting axis that is different from an axis of rotation around which the casement is otherwise pivoted when the building closure element is opened.

The shock sensor is designed to detect shocks and / or vibrations and is used, for example, to detect an attempted break-in. Additionally or alternatively, the handle position sensor can be used to determine the position in which the operating handle of the building closure element is located. The operating handle is used to operate of the building locking element or the connecting rod fitting, in particular for moving the connecting rod. For this purpose, the actuating handle is preferably operatively connected or coupled to the drive rod via the gear mechanism already mentioned above.

The pressure sensor is used to detect a force acting on the locking element, for example a shear force. Such a shear force is brought about, for example, by a force acting on the drive rod aimed at displacement. In particular, if this force exceeds a breaking force of the locking element, the integrity of the locking element may be impaired, namely the locking element may break. Such can be detected by means of the breakage sensor. The sensors mentioned serve to reliably identify the status of the espagnolette fitting and / or the building closure element. In particular, the locking device can provide a signal for a central control unit, for example a central control unit of a house control and / or an alarm system, as a function of measured values of the at least one sensor or the sensors.

Finally, within the scope of a preferred further embodiment of the invention, it can be provided 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 acts at least temporarily on the drive rod in order to displace it in a linear direction. The drive rod drive is particularly preferably an electric drive rod drive. The locking device serves not only to fix or release the drive rod with respect to the faceplate, but also to move it. A particularly high degree of integration of the drive rod and a high degree of flexibility are thus achieved.

The invention further relates to a building locking element with a connecting rod fitting, in particular a connecting rod fitting according to the statements in the context of this description, wherein the connecting rod fitting has at least one drive rod mounted linearly displaceably on a frame element of the building closure element and a faceplate attached to the frame element and covering the drive rod, wherein the drive rod can be fixed with respect to the frame element by means of a locking device. It is provided that the locking device in a locking position directly couples the drive rod to the faceplate and fixes it with respect to it and, in a release setting, releases the drive rod for displacement with respect to the faceplate.

The advantages of such a design of the building closure element or the espagnolette fitting have already been pointed out. Both the building closure element and the espagnolette fitting can be developed in accordance with the explanations in this description, so that reference is made to them in this respect.

Another preferred embodiment of the invention provides that the locking device is arranged at least in some areas in a recess in the frame element. The recess adjoins, for example, the groove in which the drive rod is arranged. In particular, the recess opens into or starts from the groove. When the locking device is arranged in the recess, the locking device is preferably arranged completely covered in the frame element. For this purpose, it is covered, for example, by the faceplate. The recess can already be formed in the frame element during manufacture. However, it can also be provided that the recess is only subsequently produced in the frame element. The latter is particularly preferably provided in the case of a retrofitting of the connecting rod fitting on the building closure element.

For example, the recess is initially not present. Rather, a connecting rod fitting different from the drive rod fitting according to the invention is mounted on the frame element or the building closure element. This is removed from the frame element. The recess is then formed in the frame element, for example by milling. Subsequently it is easily possible to attach the espagnolette according to the invention to the frame element. Ultimately, with such a procedure, it is possible to exchange the connecting rod fitting not according to the invention for a connecting rod fitting according to the invention, so that subsequently a reliable locking of the drive rod with respect to the faceplate by means of the locking device and correspondingly a reliable fixing of the drive rod with respect to the frame element even without a supporting design of the frame element, for example by Providing a corresponding reinforcement can be implemented.

It can of course also be provided, instead of arranging 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 the frame element used for its attachment. In this case, the locking device is closed Building closure element preferably arranged in a rebate area that is present between the frame and the casement.

An embodiment of the invention is also preferred in which it is provided that an actuating handle is arranged on the frame element, which is operatively connected to the drive rod via a gear mechanism for its displacement, and / or that the locking device has a drive rod drive for linear displacement of the drive rod. To move the drive rod in the linear direction, the operating handle, the drive rod drive or both are provided. The actuation handle is mounted on the building closure element or its frame element, for example rotatably mounted. The operating handle is in operative connection with the drive rod via the gear or is coupled to it via the gear. The transmission is preferably provided and designed to convert a rotary movement of the actuating handle into a linear displacement of the drive rod. The drive rod drive integrated in the locking device is preferably an electrical drive rod drive which has at least one electrical 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 between the drive rod and the faceplate when the locking setting is present, the predetermined breaking point being designed to ensure an emergency opening of the building closure element by means of the actuating handle. With the aid of the locking device, a reliable fixing of the drive rod with respect to the faceplate is thus realized. At the same time, however, it is ensured that the building closure element can be opened in an emergency. To do this, however, it is necessary to move the drive rod from the locking position into the release position. This can only be done if the drive rod can be displaced with respect to the faceplate.

For this reason, provision is made, for example, for a force to be applied via the actuating handle which leads to the breaking of the locking element at the predetermined breaking point. The force required for this is significantly greater than a force occurring during normal use of the building closure element. The force leading to the calculation of the locking element can preferably only be applied via the actuating handle if an additional element is arranged on this, for example a handle extension. Alternatively or additionally, it can 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, its housing and / or the building closure element have an access option to the locking element. The access option is realized, for example, by means of an access opening through which a user of the building closure element can grip the locking element, in particular move it, preferably only from the inside or from an interior of the building. The attack takes place, for example, directly or indirectly by means of a corresponding tool. For example, on the housing and / or the building closure element, an operating element different from the actuating handle can be arranged, which is directly coupled to the locking element. By engaging the locking element and / or actuating the operating element, the locking element can be moved into the second position, in particular from the first position into the second position. With the aid of the access option, the building closure element can also be opened when the power is off and / or the locking device is defective.

The invention also relates to a method for operating a connecting rod fitting for a building locking element, in particular a building locking element according to the statements within the scope of this description, the connecting rod fitting via at least one drive rod that can be linearly displaceable on a frame element of the building locking element and a drive rod that can be fastened to the frame element and covers the drive rod Has faceplate, wherein the drive rod can be fixed in relation to the frame element by means of a locking device. It is provided that the locking device couples the drive rod directly to the faceplate in a locking setting and fixes it with respect to this and, in a release setting, releases the drive rod for displacement with respect to the faceplate, one setting being selected from the locking setting and the release setting and set on the locking device . With regard to possible configurations of the drive rod 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 the pressure force exceeds a pressure force threshold. The compressive force is, for example, in the form of a shear force on the locking element before, which occurs when trying to move the drive rod with respect to the faceplate. This compressive force or shear force is determined, for example with the aid of a pressure sensor arranged in the locking element. If this pressure exceeds the pressure threshold, the alarm signal is generated.

The alarm signal is fed to a central control of a house control and / or an alarm system, for example. It can be provided that the generation of the alarm signal is only carried out if it is additionally determined by means of a handle position sensor for detecting a position of an operating handle of the building locking element that the operating handle is currently not being operated. In this case it can be concluded that the compressive force is exerted on the connecting rod as part of a break-in attempt. With such a configuration, a particularly high level of security for the espagnolette against attempted break-ins is achieved.

In a preferred embodiment of the invention it can be provided that the central control activates the locking device and selects a setting from the release setting and the locking setting and sets it on the locking device. For example, the central control monitors whether at least one resident 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. Provision can be made for the locking element to be displaced directly when the locking device is activated by the central control, namely either into the first position or the second position.

However, it can also be provided that the shifting of the locking element into the first position occurs immediately when the locking setting is set, but the shifting into the second position is only delayed when the release setting is set. According to the invention, it is provided that an actuation of the actuating handle is sensed and the locking element is only moved into the second position upon detection of such actuation, if the central control has previously set the release setting and this is still present. The sensing takes place by means of a suitable sensor, which is arranged, for example, on the actuating handle of the building locking element. The sensor can be 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 is caused by the user attacking the actuating handle becomes. With such a procedure, the energy consumption of the locking device is significantly reduced because the locking element is only moved into the second position corresponding to the release setting when the building locking element is actually to be opened. The force sensor is provided and designed, for example, to detect a displacement force acting on the push rod. For this purpose, the force sensor can be connected to the push rod, in particular arranged on it. An embodiment is particularly preferred in which the locking element is spring-preloaded in the direction of one of the positions, in particular in the direction of the first position. In this respect, the locking element can be displaced in the respective direction without using the actuator. In the opposite direction, however, the locking element must be displaced by means of the actuator against the spring force. The spring preload is (re) built up. For example, the locking device is designed such that when the building closure element is closed and / or locked, the locking element is automatically displaced into the first position so that the locking setting is present after closing or locking and the drive rod is reliably fixed.

Finally, the invention relates to a method for mounting a connecting rod fitting on a building locking element, in particular a connecting rod fitting according to the statements in the context of this description, the connecting rod fitting via at least one drive rod that can be linearly displaceable on a frame element of the building closure element and one that can be fastened to the frame element and covers the drive rod Has faceplate, wherein the drive rod can be fixed in relation to the frame element by means of a locking device. It is provided that the locking device couples the drive rod directly to the faceplate in a locking setting and fixes it with respect to this and, in a release setting, releases the drive rod for displacement with respect to the faceplate, the locking device being fastened to the faceplate and together with the drive rod fitting removed from the building closure element the drive rod of the faceplate is attached to the frame element of the building locking element and wherein an actuation of an actuating handle of the building locking element is sensed and the locking element is only shifted into the release position when such an actuation is detected if a central control has previously set a release setting.

With regard to possible configurations of the building closure element or the method for its assembly, reference is again made to the statements in the context of this description, which can be used as a supplement.

Provision is made for the locking device to be arranged on the espagnolette fitting and to be fastened as long as it is removed from the building closure element. It is therefore provided, for example, to arrange the locking device on the connecting rod fitting and to fasten it together with the connecting rod and the faceplate to the frame element before the connecting rod fitting is installed on the building closure element or the frame element. For example, the connecting rod fitting is initially 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 drive rod fitting and the drive rod fitting is fastened again to the building closure element. However, provision can also be made to remove a drive rod fitting not according to the invention from the building closure element and replace it with a drive rod fitting to which the locking device is attached. In both cases, easy retrofitting of the locking device is guaranteed.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without restricting the invention. It shows:

Figure 2

Another schematic representation of the espagnolette fitting.

The Figure 1 shows a schematic representation of a region of a drive rod fitting 1 for a building closure element (not shown). The building closure element is, for example, in the form of a window, a door or the like. The drive rod fitting 1 has a drive rod 2 which can be linearly displaced. Furthermore, there is a faceplate 3 which covers the drive rod 2 at least in some areas. The faceplate 3 is usually fastened directly to a frame element of the building closure element, namely by means of a screw connection and / or at least one fastening element 4, preferably - as shown here - several fastening elements 4. The fastening elements 4 are in the embodiment shown here as screws, which with their screw head rest on the faceplate 3 and, on the other hand, engage in the frame element of the building closure element. The fastening element 4 can - if necessary - reach through the drive rod 2. For this purpose, an elongated hole 5 is formed in the drive rod 2, which a displacement of the drive rod 2 in the linear direction in spite of reaching through the fastening element 4 is possible. The linear movement of the drive rod 2 is indicated by the double arrow 6.

The drive rod fitting 1 also has a locking device 7, which enables the drive rod 2 to be fixed with respect to the frame element. More precisely, when a locking setting is present, the locking device 7 fixes the drive rod with respect to the faceplate 3, namely by coupling the drive rod 2 directly to the faceplate 3. For this purpose, a locking element 8 is provided, which can be displaced in the linear direction according to the double arrow 9. The locking element 8 is in the form of a locking bolt, for example. To move 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 rack gear 11. The actuator 10 is preferably arranged in a housing 12 of the locking device 7.

The drive rod 2 is directly coupled to the faceplate 3 by the locking element 8 engaging or reaching through both in or through a locking recess 13 of the drive rod 2 and in or through a locking recess 14 of the faceplate 3. In particular, it is provided that the locking element 8 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 the two locking recesses 13 and 14. For example, it is arranged completely in the housing 12, that is to say it is present on the side of the drive rod 2 facing away from the faceplate 3, in particular completely.

A control device 15, which is used to control the actuator 10, can be present in the housing 12. The actuator 10 and the control device 15 can be supplied with energy by means of an energy store 16, which in the exemplary embodiment shown here has at least one battery 17. The control device 15 can have at least one sensor. Thus, a condition sensor 18 is preferably provided which interacts with a magnet 9 in order to determine an opening condition of the building closure element. The magnet 19 is arranged on the respective other frame element than the locking device 7. For example, the magnet 19 is on a frame and the locking device 7 is on a casement of the building closure element.

Furthermore, a position sensor 20 can 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 whether the drive rod 2 is arranged for locking or for unlocking the building locking element. In the case of the unlocked building locking element, it is particularly preferably possible to use the position sensor 20 to determine whether a turn opening or a tilt opening of the building locking element (if the building locking element is configured as a turn-tilt 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 device of a house control or an alarm system. Furthermore, a position sensor 27 can be present, by means of which a position of the locking element 8 can be detected. With the aid of the position sensor 27 it can be determined whether the locking element 8 has correctly fixed the drive rod.

The Figure 2 shows a further representation of the espagnolette 1. It can be seen that the locking device 7 is positively connected to the faceplate 3 during assembly. For this purpose, the locking device 7 or its housing 12 has form-locking devices 22, in the exemplary embodiment shown here, form-locking projections, which are brought into form-locking connection with form-locking mating devices 23 of the faceplate 3 during assembly. In the exemplary embodiment shown here, the form-locking counter-devices 23 are designed as form-locking recesses.

Provision is particularly preferably made for the locking device 7 to be mounted, that is, the establishment of the form-fit connection between the form-fit device 22 and the form-fit counter-device 23, by screwing in the locking device 7 with respect to the faceplate 3. This is indicated by the arrows 24.

Also indicated is a gear 25 for the mechanical connection of an actuating handle (not shown) to the drive rod 2. The gear 25 has a handle receptacle 26 for receiving the actuating handle or its connection, in which a region of the actuating handle can be positively arranged. The gear 25 is used to convert a rotary movement of the operating handle into a linear movement of the drive rod 2.

The drive rod fitting 1 described has the advantage that, on the one hand, a reliable and secure fixing of the drive rod 2 with respect to the frame element is achieved, namely by direct coupling of the drive rod 2 to the faceplate 3. On the other hand, the building closure element can also be retrofitted with the locking device 7 without problems.
