Description

The invention relates to an actuation apparatus for a locking mechanism of a door or of a window, in particular of a terrace door.

Such actuation apparatus are, for example, used for retrofitting installed doors or windows. Actuation apparatus comprising an electromechanical drive device can facilitate the actuation of the locking mechanism of a door or of a window for the user and allow an actuation from outside a flat or a building in connection with a remote control. With a terrace door, which is usually only manually unlocked or locked from the inner side of a flat or of a building by means of a handle element, it can, for example, be desirable to also occasionally carry out an unlocking and/or a locking from the outer side of the flat or of the building without a complete replacement of the already present locking mechanism having to be necessary for this extended actuation option. The locking mechanism of a terrace door or of a window typically comprises a rotational bolt and/or an integrated operating rod arrangement which can be actuated by means of a handle element via a shaft element, with this shaft element usually being configured as a square pin.

An actuation apparatus comprising an electromechanical drive device is known from DE 10 2004 021 704 B3. The electromechanical drive device is here selectively actively decoupled from a shaft element by means of an additional actuator.

An actuation apparatus in accordance with the preamble of claim 1 is disclosed in US 2013/0245833 Al. Further actuation apparatus are known from WO 2006/115335 Al, EP 2 592 203 A2 and DE 299 18 033 Ul.

It is an object of the invention to provide an actuation apparatus for a locking mechanism of a door or of a window in which a manual actuation of the locking mechanism is possible alternatively to an electromechanical actuation of the locking mechanism without a decoupling of the electromechanical drive device by means of an additional actuator being necessary for this purpose.

This object is satisfied by an actuation apparatus having the features of claim 1.

Such an actuation apparatus comprises a shaft element which is or can be (directly or indirectly) coupled to the locking mechanism of the door or of the window and which, in a manual actuation operation, can be manually rotated by a user (preferably by means of an associated handle section) about a main axis at least between an open position and a closed position in order to actuate the locking mechanism in an opening sense or in a closing sense. The actuation apparatus furthermore comprises an electromechanical drive device; and an entrainment element which can be driven by means of the drive device to carry out a rotational movement (preferably likewise about the main axis). The entrainment element can selectively be coupled (directly or indirectly, in particular via an abutment element which will be explained in the following) to the shaft element (by a corresponding rotation by means of the drive device). The shaft element can hereby be electromechanically rotated between the open position and the closed position by means of the drive device (namely via the entrainment element) in an electromechanical operation of the actuation apparatus. For the manual actuation operation of the actuation apparatus, the entrainment element can, in contrast, be rotated by means of the drive device into a position of rest in which the entrainment element is decoupled from the shaft element. The shaft element can hereby be manually rotated by the user in the manual actuation operation without the manual actuation operation being impeded by the drive device and in particular by the entrainment element. A manual locking from the inner side of a flat or of a building is thus possible with the actuation apparatus, while an electromechanical opening and/or closing from the outer side is simultaneously possible (and can in particular be triggered by remote control). In the actuation apparatus in accordance with the invention, the electromechanical drive device is not mechanically influenced during a manual actuation of the shaft element. The shaft element can be manually rotated by means of an associated handle section into its functional positions, for example the open position and the closed position, without a drive shaft of the electromechanical drive device hereby being rotated. A resting torque of the electromechanical drive device thereby does not have to be overcome on a manual actuation, which would require an undesirably high exertion of force, in particular if the electromechanical drive device comprises a reduction gear. Such a decoupling therefore facilitates the manual actuation of the locking mechanism. Wear at the electromechanical drive device is thus furthermore considerably reduced. In addition, a source of energy, for example a battery, provided for the drive device is spared.

In other words, the electromechanical drive device is indeed coupled via an entrainment element to the shaft element (i.e. brought into a drive-effective connection) for an electromechanical actuation and the electromechanical drive device is hereby able to act on the shaft element in order to drive the shaft element to carry out a desired rotational movement. The entrainment element can, however, also be brought into a position of rest by the same electromechanical drive device. In this position of rest, the entrainment element is decoupled from the shaft element and a manual actuation of the shaft element uninfluenced by the drive device is thus possible.

If an electromechanical actuation is, for example, requested by a remote control, the electromechanical drive device can rotate the shaft element via the entrainment element from one functional position into another functional position. The actuation apparatus in accordance with the invention can thus also be actuated from outside a flat or a building. Since no active decoupling has to be provided between the electromechanical drive device and the locking mechanism by means of an additional actuator, the actuation apparatus can be designed as simple, small in construction, and inexpensive.

The invention in particular makes use of the fact that the shaft elements, such as square pins, in locking mechanisms of doors or of windows are usually only rotated over a limited angular range on the actuation. This angular range typically amounts to 180° with a tum-and-tilt leaf, for example. The remaining angular range can thus be utilized to allow the entrainment element to dwell in the position of rest there for a manual actuation operation of the actuation apparatus.

Advantageous embodiments of the invention will be described in the following.

The actuation apparatus can comprise a control device which is adapted to control the drive device for rotating the entrainment element in a closing rotational direction for an electromechanical closing actuation to rotate the shaft element into the closed position by means of the entrainment element; to control the drive device for rotating the entrainment element in an opening rotational direction opposite to the closing rotational direction for an electromechanical opening actuation to rotate the shaft element into the open position by means of the entrainment element; and to control the drive device for rotating the entrainment element into the position of rest for the manual actuation operation of the actuation apparatus, namely between an electromechanical closing actuation and an opening actuation. The control device can in particular be adapted to selectively control the drive device for rotating the shaft element into the closed position or for rotating the shaft element into the open position, for example on the basis of control commands which are received via a connected radio receiver. The different functional positions of the shaft element can thus either be set automatically by means of the control device or the actuation apparatus is released for a manual actuation operation (by means of a handle section associated with the shaft element).

In accordance with an advantageous embodiment, the actuation apparatus comprises an abutment element which is connected to the rotatable shaft element (directly connected, in particular rotationally fixedly or in one piece, or indirectly connected). The entrainment element can selectively be brought into contact with the abutment element by means of the drive device to - as explained - couple the entrainment element to the shaft element (i.e. to connect in a drive-effective manner). As soon as this coupling is established, the shaft element can be electromechanically rotated between the open position and the closed position by means of the drive device via the entrainment element and via the abutment element. The abutment element thus enables or simplifies the explained coupling of the entrainment element to the shaft element, in particular when the shaft element is configured as a conventional square pin. The entrainment element can in particular selectively abut the abutment element to subsequently be able to transmit a torque to the abutment element and thus to the shaft element. The entrainment element is, in contrast, released from the abutment element (i.e. brought out of contact) in said position of rest.

The abutment element can be an integral part of the shaft element or a separate part and it is preferably arranged off-center with respect to said main axis or to the axis of rotation of the shaft element. The abutment element is preferably rotationally fixedly connected to the shaft element. However, it is generally also possible that a drive-effective connection with a predetermined rotational clearance is provided between the abutment element and the shaft element.

Said abutment element preferably rotates about the main axis along a predetermined trajectory on a rotational movement of the shaft element between the open position and the closed position, with the entrainment element being located outside the predetermined trajectory of the abutment element in the position of rest. In other words, said position of rest of the entrainment element is selected such that the entrainment element is located outside the trajectory along which the abutment element rotates when the shaft element is manually rotated between the open position and the closed position. It is hereby achieved that the entrainment element is decoupled from the shaft element for the manual actuation operation and that the shaft element can be manually rotated by the user without an interaction with the drive device or with the entrainment element taking place in so doing.

The axis of rotation of the entrainment element and the axis of rotation of the abutment element can be aligned coaxially with respect to one another and to the main axis (that is to the axis of rotation of the shaft element). The entrainment element and the abutment element can thereby harmonically engage into one another over the total rotational range.

The predetermined trajectory of the abutment element can be bounded in a swept-over angular range and the entrainment element can be located outside this angular range of the abutment element in its position of rest.

The angle sum of (a) the angular range which the abutment element sweeps over on a rotational movement of the shaft element between the open position and the closed position, and (b) the angular range which the abutment element covers (when stationary, i.e. due to its extent), and (c) the angular range which the entrainment element covers can be smaller than 360° by an angle difference (whose amount is larger than 0°). This allows a specific clearance on the actuation of the locking mechanism, that is a rotational clearance of the entrainment element in its position of rest relative to the abutment element in the open position and/or in the closed position of the shaft element. The electromechanical drive device, the entrainment element and the abutment element are thus spared mechanically since, due to the clearance, an abutment of the entrainment element at the abutment element does not have to occur on each manual actuation. A rotational clearance can in particular be used for a control of a blocking device explained further below.

In an embodiment, the abutment element sweeps over an angle of rotation of 90° on a rotational movement of the shaft element between the open position and the closed position.

The shaft element can, however, also be manually rotatable between the open position, the closed position and additionally a tilt position, with the abutment element rotating along a total path on a rotational movement of the shaft element between the open position, the closed position and the tilt position, said total path corresponding to said trajectory (in particular when the tilt position is located between the open position and the closed position) or being larger than said trajectory (in particular when the tilt position is located beyond the open position or the closed position), with the entrainment element preferably being located outside said total path of the abutment element in the position of rest. The actuation apparatus comprising the advantages in accordance with the invention is thereby also made usable for those windows and doors that provide a tilt position, such as windows or terrace doors or balcony doors comprising a tum-and-tilt leaf.

In such an embodiment, the abutment element preferably sweeps over an angle of rotation of 180° on a rotational movement of the shaft element between the open position, the closed position and the tilt position.

If a tilt position of the door or of the window is provided in addition to the open position and to the closed position, the angle sum of (a) the angular range which the abutment element sweeps over on a rotational movement of the shaft element between the open position, the closed position and the tilt position, and (b) the angular range which the abutment element covers, and (c) the angular range which the entrainment element covers can correspondingly, as explained above, be smaller than 360° by an angle difference (whose amount is larger than 0°).

So that the entrainment element can come into contact with the abutment element during its rotational movement to subsequently transmit a torque to the abutment element, the entrainment element can comprise a first cam which projects axially and/or radially with respect to the main axis from a rotatably supported entrainment element carrier, with the abutment element comprising a second cam which projects axially and/or radially with respect to the main axis from an abutment element carrier. The first cam in particular projects in a direction opposite to the projection direction of the second cam. The entrainment element carrier is driven to carry out a rotational movement by means of the drive device. The abutment element carrier is coupled to the rotatable shaft element.

In addition, two or more abutment elements, in particular at a common abutment element carrier, and two or more entrainment elements, in particular at a common entrainment element carrier, can be provided in the actuation apparatus. The force transmission from the electromechanical drive device to the shaft element is thereby distributed over two or more contact points between abutment elements and entrainment elements. The load on and wear of individual abutment elements and entrainment elements are thus reduced.

In accordance with the invention, the actuation apparatus furthermore has a fixing element and a blocking device, with the shaft element being latched and/or blockable relative to the fixing element at least in the closed position. In this respect, the blocking device is selectively displaceable into a blocking state in which the fixing element is fixed in a stationary manner (e.g. relative to a housing or to a fastening plate) or into a release state in which the fixing element is released for a rotational movement together with the manually rotated shaft element. The blocking device is in this respect displaceable into the blocking state in a simple manner in that the drive device rotates the entrainment element into the position of rest and the blocking device is displaceable from the blocking state into the release state in that the drive device rotates the entrainment element into a release position which differs from the position of rest (in particular offset from the position of rest in the peripheral direction).

The release position can in particular lie between the position of rest and the trajectory (or said total path) of said abutment element. In other words, the release position corresponds to an intermediate position in which the entrainment element is indeed already brought out of the position of rest (which corresponds to the blocking state), but cannot yet be in contact with the shaft element or with said abutment element (for driving the shaft element). The locking mechanism can thereby also be actuated by the electromechanical drive device when the shaft element is latched and/or blocked relative to the fixing element. If the shaft element latches relative to the fixing element, the shaft element can thus be rotated without overcoming latching forces and the locking mechanism can be actuated. The source of energy, for example a battery, of the electromechanical drive device is thus spared even further and the wear at the mechanical components is reduced. If the shaft element is blocked relative to the fixing element (e.g. by means of a lock cylinder or a push button closure, as will be explained in the following), an electromechanical actuation is nevertheless enabled despite the blocking.

The blocking device can comprise a blocking section of the actuation apparatus fixed in a stationary manner (e.g. fixed to the housing) and a movably supported blocking element, with the fixing element having at least one blocking element engagement recess. In this respect, the blocking element engages into both the blocking section (e.g. into a guide or recess provided there) and the blocking element engagement recess of the fixing element in the blocking state and hereby blocks the fixing element relative to the blocking section (in particular by a mutual shape match). In the release state, in contrast, the blocking element is brought or able to be brought out of engagement with the blocking section or with the blocking element engagement recess (in particular in order to cancel said mutual shape match). This is a particularly simple and effective way of establishing a blocking of the fixing element relative to the blocking section. The blocking element is preferably movably supported at the blocking section, with the blocking element at the blocking section being able to be tangentially fixed with respect to the main axis. The blocking element can, however, also be movably supported at the fixing element (in particular in said blocking element engagement recess), with the blocking element then rotating together with the fixing element or the shaft element in the release state.

The blocking element can be movably supported (at the blocking section or at the fixing element) with respect to the main axis in the radial direction, with the entrainment element or an entrainment element carrier having the entrainment element comprising a projection which is adapted to urge the blocking element into engagement with both the blocking section and the blocking element engagement recess of the fixing element when the entrainment element is rotated into the position of rest. This embodiment represents a functional integration of additional functions into the entrainment element or the entrainment element carrier. Individual parts and construction space are thereby saved and costs are lowered. In this respect, the entrainment element or the entrainment element carrier can comprise a release section adjacent to the projection, said release section being adapted to release the blocking element for an escape from the blocking section or from the blocking element engagement recess of the fixing element when the entrainment element is rotated into the release position.

The actuation apparatus can comprise a latching device which comprises said fixing element, a counter fixing element rotationally fixedly coupled to the shaft element, and at least one spring-preloaded snap-in element (e.g. a latching ball), with the snap-in element establishing a respective snap fit between the fixing element and the counter fixing element in the open position and in the closed position of the shaft element. In this respect, the fixing element can, for example, be formed by a latching plate and the counter fixing element can be formed by a snap-in element carrier or by such an element. Conversely, the fixing element can be formed by a snap-in element carrier and the counter fixing element can be formed by a latching plate or by such an element.

The actuation apparatus can alternatively or additionally comprise a blocking apparatus which comprises said fixing element and a blocking member which is provided at the shaft element and which can selectively be brought into engagement with the fixing element by manual actuation to block the shaft element relative to the fixing element at least in the closed position. The blocking member can, for example, comprise a lock cylinder or a push button closure or a part thereof (e.g. a locking pin). The actuation apparatus can therefore be closed in this respect, which can improve the security against break-ins from the outside and can prevent an erroneous operation from the inside. The locking mechanism can nevertheless continue to be actuated by the electromechanical drive device, in particular from the outside. An access from the outside via a remote control also remains ensured with a closed actuation apparatus.

The shaft element is preferably rotationally fixedly connected to a handle section (which is integral or separate) to enable a manual rotational actuation of the shaft element.

The shaft element can comprise a square pin to which a handle element is rigidly fixed to form said handle section. A square pin as a shaft element can be connected particularly easily to common already installed doors or windows. The handle element facilitates the handling by the user.

The electromechanical drive device can comprise an electric motor and a reduction gear, with the entrainment element being provided at an output element of the reduction gear. This is a further step for functional integration, whereby further individual parts are saved. The output element of the reduction gear can in this respect be configured as a sprocket which is formed at the entrainment element or at an entrainment element carrier.

The object of the invention is furthermore satisfied by a locking apparatus of a door or of a window which comprises an actuation apparatus in accordance with the invention (in any one of the embodiments explained above); and at least one locking element which is (preferably rotationally fixedly) coupled to the rotatable shaft element and which locks the door or the window in the closed position.

Furthermore, the object of the invention is also satisfied by the use of an actuation apparatus in accordance with the invention (in any one of the embodiments explained above) for actuating a locking mechanism of a door or of a window.

In the two last-named solutions, the shaft element can in particular have a square pin which engages in a shape-matched manner into an associated reception opening of the locking mechanism of the door or of the window. The locking mechanism of the door or of the window can in particular comprise an operating rod arrangement which is integrated (into the door leaf, into the door frame or into the window frame) and which is actuated via the shaft element. The actuation apparatus can in particular be used for actuating the locking mechanism in a retrofit solution as a replacement for the originally provided handle element.

Further embodiments of the invention are set forth in the dependent claims, in the description and in the drawings.

Fig. 1 shows an actuation apparatus 20 in accordance with the invention comprising an electromechanical drive device 26 and a handle element 24. The electromechanical drive device 26 comprises an electric motor 50 and a reduction gear 52. The handle element 24 forms the rotationally fixedly connected handle section of a rotatable shaft element 22 which is configured as a square pin and is covered in this view (cf. Figs. 5 and 15). An entrainment element carrier 32 comprises a sprocket 60 at its outer side which forms the output element of the reduction gear 52. The entrainment element carrier 32 is arranged axially adjacent to an abutment element carrier 34 which is rotationally fixedly connected to the shaft element 22, with parts of the entrainment element carrier 32 engaging into the abutment element carrier 34, as will be explained in the following. In this respect, a main axis A, to which reference is made here and which is not shown here (cf. Figs. 14 and 15), extends along the covered shaft element 22 and forms the axis of rotation of the shaft element 22 and of the entrainment element carrier 32 rotatable relative to the shaft element 22. A pivotable latch 54 rotationally fixedly connected to the shaft element 22 is arranged beneath the abutment element carrier 34 and optionally forms a part of a locking mechanism of a door or of a window which is actuated by means of the actuation apparatus 20.

The embodiment shown in the Figures is an actuation apparatus 20 for a right-handed window or door. The leaf of the window or door is therefore hinged or fastened to the frame at the right from the viewpoint of the user on the opening of the leaf toward the user (also called "DIN right"). The embodiment can easily be transferred to left-handed windows or doors in a mirror-inverted manner, for example.

The actuation apparatus 20 comprises batteries 56 for a power supply of the electric motor 50. A mains power supply can, however, also be provided, for example.

The handle element 24 comprises a lock cylinder 58 by which a blocking member 48, which is covered here, can be brought into engagement by means of a key (cf. Fig. 15).

The actuation apparatus 20 can therefore be terminated by the lock cylinder 58 to prevent a manual operation by unauthorized persons or children, for example.

Fig. 2 shows the entrainment element carrier 32 which is substantially configured as circular and for rotation. The entrainment element carrier 32 can be driven by the electric motor 50 of Fig. 1 for rotation via the sprocket 60 at the outer side. The entrainment element carrier 32 is designed in the manner of a pot, with a projection 42 being formed at its inner wall. The holding surface of the projection 42 facing the axis of rotation is formed for holding a blocking element 38, not shown, in a blocked position (cf. Fig. 5). The slanted secondary surfaces of the projection 42 adjacent to the main surface are formed to urge the blocking element 38 into the blocked position or release it therefrom in a controlled manner on a rotation of the entrainment element carrier 32 in the radial direction.

Fig. 3 shows the entrainment element carrier 32 comprising the sprocket 60 from a different perspective. The entrainment element carrier 32 has two entrainment elements 28 which are effective as first cams. The one entrainment element 28 is shaped as a radially inwardly protruding projection at the base of the pot-like entrainment element carrier 32. The other entrainment element 28 is arranged as an axial projection at a rotational guide surface 62 which is a part of a rotational guide for the entrainment element carrier 32 and which is designed as a cylindrical outer surface.

Fig. 4 shows the abutment element carrier 34 comprising two abutment elements 30 configured as axial projections. The two abutment elements 30 are effective as second cams. Since each of the two entrainment elements 28 of the entrainment element carrier 32 (Fig. 3) cooperates with one of the two abutment elements 30 and the two pairs of the entrainment element 28 and of the abutment element 30 are axially offset from one another with respect to the main axis A, a better distribution of the torque transmission is achieved on a mutual contact. The abutment element carrier 34 comprises a rotational guide surface 64 which is formed as a cylindrical inner surface. The rotational guide surface 62 of the entrainment element carrier 32 of Fig. 3 cooperates with the rotational guide surface 64 of the abutment element carrier 34 in order to rotatably support the entrainment element carrier 32 relative to the abutment element carrier 34. In this respect, the entrainment elements 28 can cooperate tangentially (i.e. in the direction of rotation) with the abutment elements 30 to drive the abutment element carrier 34 to carry out a rotational movement on a rotation of the entrainment element carrier 32. The abutment element carrier 34 is rotationally fixedly connected to the shaft element 22, not shown here, via a square receiver 66 (cf. Fig. 6). The shaft element 22 can thus be driven to rotate by the electric motor 50 via the reduction gear 52, via the entrainment element carrier 32, via the cooperation of the entrainment elements 28 with the abutment elements 30 and via the abutment element carrier 34.

Fig. 5 shows a sectional view of the actuation apparatus 20. The sectional plane extends along a first sectional plane which respectively corresponds to the sectional planes of Figs. 7, 9 and 11. Fig. 6 shows the actuation apparatus 20 in a sectional view along a second sectional plane which respectively corresponds to the sectional plane of Figs. 8, 10 and 12. The first and second sectional planes extend in parallel with one another and perpendicular to the shaft element 22 and to the main axis A which is in turn perpendicular to the image plane shown. The first and second sectional planes are, however, axially spaced apart, with the second sectional plane lying beneath the first sectional plane.

In Fig. 5 (closed position), the rotatable entrainment element carrier 32 comprising the projection 42 and a fixing element 36 (cf. Fig. 13) are shown, said fixing element likewise being rotatable about the main axis A and comprising four blocking element engagement recesses 40 provided at the outer periphery in a uniform manner, i.e. in a 90° division. A pin-shaped blocking element 38 aligned in parallel with the main axis A engages into one of the blocking element engagement recesses 40 (cf. Figs. 14 and 15) and thus fixes the fixing element 36 tangentially, that is against a rotation. The blocking element 38 is, for example, tangentially fixed, but radially displaceably supported, in a non-visible plane in a radially extended groove of a housing section, not shown, which thus serves as a blocking section. A counter fixing element 44 (cf. Figs. 14 and 15) rotationally fixedly connected to the shaft element 22 likewise has four snap-in elements 46 in a 90° division which are configured as latching balls and are upwardly spring-preloaded, i.e. in the direction of the fixing element 36, in parallel with the main axis A. In Figs. 5 and 6, the electric motor 50 and the latch 54 are furthermore shown, said latch being located in the closed position like the handle element 24 and locking the right-handed door or window with respect to the left part of a frame, not shown.

In Figs. 5 and 6, the shaft element 22 is shown which defines the axis of rotation of the components as the main axis A which extends through the center of the square cross-section of the shaft element 22 and perpendicular to the image plane. In Fig. 6, the abutment element carrier 34 is furthermore visible with one of the abutment elements 30.

One of the entrainment elements 28 which can be driven by the electromechanical drive device 26 to carry out a rotational movement about the main axis A is located in the direction of rotation at a free angular spacing D/2 adjacent to the abutment element 30 of Fig. 6. The free angular spacing D/2 corresponds to half the difference of 360° less the sum of: (a) the angular range which the abutment element 30 sweeps over on a rotation of the shaft element 22 between the closed position (Figs. 5 and 6), an open position (Figs. 7 and 8) and a tilt position (Figs. 9 and 10) (here 180°); (b) the angular range which the abutment element 30 covers; and (c) the angular range which the entrainment element 28 covers. Viewed conversely, this means that the angle sum of (a) the angular range which the abutment element 30 sweeps over on a rotational movement of the shaft element 22 between the closed position, the open position and the tilt position, (b) the angular range which the abutment element 30 covers, and (c) the angular range which the entrainment element 28 covers is smaller than 360° by an angle difference D so that the entrainment element 28 always has a specific rotational clearance relative to the abutment element 30 independently of the position of the shaft element 22.

The handle element 24, not shown here, is so-to-say at 6 o'clock in Figs. 5 and 6, i.e. the handle element 24 extends perpendicular downwardly in the image. The abutment element 30 is rotationally fixedly connected to the shaft element 22 and therefore to the handle element 24 and is at 3 o'clock in the closed position shown, i.e. it is arranged at the right of the main axis A in the image. The entrainment element 28 is here at 6 o'clock in its position of rest.

In Figs. 7 to 12, the same individual parts as in Figs. 5 and 6 are shown in a corresponding manner so that reference will only be made to selected functional elements in the following.

In Figs. 7 and 8, the handle element 24, not shown, of the actuation apparatus 20 is at 3 o'clock in an open position. The abutment element 30 which had been rotationally fixedly connected to the handle element 24 and manually rotated by means of the handle element 24 covered a trajectory of 90° and is now at 12 o'clock. The end of the latch 54 which is visible in Figs. 5 and 6 is at 6 o'clock in the open position and is therefore covered and not visible in Figs. 7 and 8. The entrainment element 28 continues to be at 6 o'clock in its position of rest. The fixing element 36 thus continues to be fixed in a stationary manner by means of the blocking element 38 acted on by the projection 42.

In Figs. 9 and 10, the handle element 24, not shown, of the actuation apparatus 20 is in a tilt position at 12 o'clock after the handle element 24 had been manually rotated further. An end of the latch 54 which is disposed opposite the end of the latch 54 which is visible in Figs. 5 and 6 is at 9 o'clock, that is at the left of the main axis A in the image. The end of the latch 54 shown in Figs. 9 and 10 is configured to allow and simultaneously limit a tilting of the door leaf or window leaf. The abutment element 30 is at 9 o'clock and the entrainment element 28 continues to be at 6 o'clock in its position of rest.

In summary, the entrainment element 28 and the entrainment element carrier 32 in Figs. 5 to 10 are always in their positions of rest in which the entrainment element 28 is decoupled from the abutment element 30 and thus from the shaft element 22. The handle element 24, not shown, and thus the shaft element 22 were merely manually rotated by 180° from the closed position (6 o'clock) over the open position (3 o'clock) up to the tilt position (12 o'clock) between the functional positions of Figs. 5 to 10 without the entrainment element 28 and the abutment element 30 having come into contact. The respective abutment element 30 in this respect rotated along a predetermined total path which corresponds to an angular range of 180° (cf. Figs. 6, 8 and 10).

Figs. 11 and 12 now show the state after a first electromechanical actuation in the opening sense which was triggered, starting from the closed position in accordance with Figs. 5 and 6, by means of a control device not shown here. A radio receiver can, for example, be connected to said control device to be able to receive corresponding control commands and transmit them to the control device. These control commands can be transmitted by a user by means of an associated radio transmitter and they are preferably encrypted. Two different control commands ("Open" and "Close") can, for example, be provided or only a single control command is provided ("Switch to the respective other functional position"). The control device initiates the moving back of the entrainment element 28 into the position of rest in an automatic manner in each case.

In Figs. 11 and 12, the handle element 24, not shown, of the actuation apparatus 20 is at 6 o'clock in the closed position. The visible end of the latch 54 is accordingly at 9 o'clock and locks the window leaf or door leaf with respect to the left frame, not shown. The abutment element 30 is at 3 o'clock in Figs. 11 and 12. In this respect, the conditions still correspond to those in accordance with Figs. 5 and 6. The entrainment element 28 is now, however, at approximately 5 o'clock outside its position of rest and abuts the abutment element 30. In other words, the entrainment element 28 was brought into contact with the abutment element 30 by means of the drive device 26 to couple the entrainment element 28 to the shaft element 22. The entrainment element 28 is, as explained, a part of the entrainment element carrier 32 which is accordingly likewise located outside its position of rest, i.e. the entrainment element carrier 32 was rotated counterclockwise by the electromechanical drive device 26 and was thus rotated out of the position of rest. The projection 42 of the entrainment element carrier 32 is now no longer at 12 o'clock in its position of rest, but rather at approximately 11 o'clock and thus no longer holds the blocking element 38 captive in the respective blocking element engagement recess 40 in the radial direction. Starting from this state, the fixing element 36 can therefore radially outwardly displace the blocking element 38 by the angle of engagement of its blocking element engagement recess 40 on a rotation and thus cancel its tangential blocking. The blocking element 38 is already shown in the state released from its blocked position in Fig. 11. The blocking element 38 is therefore no longer in engagement with one of the blocking element engagement recesses 40 and no longer blocks the fixing element 38 against a rotation about the main axis A.

In other words, Figs. 11 and 12 show a snapshot during an electromechanical opening actuation of the locking mechanism which should move the locking mechanism from the closed position into the open position. The shaft element 22 and the parts rotationally fixedly connected thereto (in particular the handle element 24, the abutment element carrier 34 comprising the abutment elements 30 and the counter fixing element 44 comprising the snap-in elements 46) are still just in the closed position in Figs. 11 and 12, wherein the entrainment element 28 (or the two entrainment elements 28 in accordance with Fig. 3) now engages at the abutment element 30 (or at the two abutment elements 30 in accordance with Fig. 4).

As a consequence, said control device causes the electromechanical drive device 26 to rotate the entrainment element carrier 32 and thus the respective entrainment element 28 by a further 90° in the opening rotational direction, i.e. counterclockwise. The entrainment element 28 hereby rotates the abutment element 30 (and thus the shaft element 22) up to 12 o'clock (corresponding to the position of the abutment element 30 in accordance with Fig. 8) so that the locking mechanism adopts the open position. The handle element 24, not shown, is thus at 3 o'clock.

After such an electromechanical opening actuation, the control device controls the electromechanical drive device 26 to rotate the entrainment element carrier 32 and thus the respective entrainment element 28 back into the position of rest so that all the components now adopt the respective position in accordance with Figs. 7 and 8 and the entrainment element 28 is decoupled from the abutment element 30 or from the shaft element 22. The actuation apparatus 20 is thus ready for a subsequent manual actuation operation (in the closing sense) since the respective entrainment element 28 is again located outside the explained trajectory or total path of the associated abutment element 30 and thus does not impede a manual rotation of the respective abutment element 30.

The blocking element 38 is out of engagement with the blocking element engagement recesses 40 almost over the total rotational path of the entrainment element carrier 32 during the explained electromechanical opening actuation and the subsequent rotating back of the entrainment element carrier 32 so that the blocking of the fixing element 36 is cancelled and the fixing element 36 can follow the rotational movement of the abutment element carrier 34 and of the shaft element 22 and handle element 24 rotationally fixedly connected thereto (due to the snap fit of the fixing element 36 with the counter fixing element 44 or shape match with the blocking member 48 of the handle element 24 which will be explained in more detail in the following). The projection 42 only forces the blocking element 38 into engagement with a blocking element engagement recess 40 in the position of rest of the entrainment element carrier 32 at the start of the electromechanical opening actuation and after the completion of the rotating-back movement of the entrainment element carrier 32. To reach the open position and to subsequently return the entrainment element carrier 32, no latching forces between the fixing element 36 and the counter fixing element 44 thus have to be overcome (whereby the energy requirements for the electromechanical actuation are reduced) and the electromechanical opening actuation is even possible when the actuation apparatus 20 is terminated by means of the lock cylinder 58.

In accordance with Fig. 11, the fixing element 36 has the four blocking element engagement recesses 40 distributed uniformly over the periphery for the stationary blocking of said fixing element. An angle of 90° is thus respectively present between the blocking element engagement recesses 40. The closed position and the open position of the shaft element 22 likewise have an angular spacing of 90°. The fixing element 36 covered an angle of 90° after a rotation of the shaft element 22 and of the fixing element 36, which is rotationally fixedly connected thereto at times, from the closed position into the open position. A blocking element engagement recess 40 is therefore again disposed opposite the blocking element 38 as soon as the open position has been reached. The entrainment element carrier 32 is - as explained - moved clockwise back into its position of rest after the electromechanical opening actuation until the entrainment element 28 is again at 6 o'clock and the projection 42 is again at 12 o'clock (cf. Figs. 7 and 8). In this respect, the slanted secondary surface of the projection 42 facing the blocking element 38 radially inwardly displaces the blocking element 38 and again brings it into engagement with a blocking element engagement recess 40, namely that one which was at 3 o'clock before the electromechanical opening actuation.

In Figs. 11 and 12, the entrainment element 28 and the projection 42 have rotated by the angular spacing D/2, indicated in Fig. 6, with respect to the state shown in Figs. 5 and 6. Against this background, Fig. 11 illustrates that this angular spacing D/2 is used to release the blocking element 38 in a controlled manner by means of the slanted secondary surfaces of the projection 42 from the engagement with the blocking element engagement recess 40. On the moving of the entrainment element 28 back into its position of rest, the angular spacing D/2 is used to urge the blocking element 38 into engagement again. The slanted secondary surfaces of the projection 42 each extend over an angular range which is smaller than or equal to the angular spacing D/2.

Fig. 13 shows the fixing element 36 comprising the blocking element engagement recesses 40 in the form of a part cylinder in each case. The fixing element 38 comprises four snap-in openings 68 for the snap-in elements 46 of the counter fixing element 44, not shown, in a 90° division (cf. Fig. 14). The spring-preloaded snap-in elements 46 are guided in a ball guide 70 of the fixing element 36 along a circular path on a manual actuation of the shaft element 22 (when the fixing element 36 is fixed in a stationary manner as in Figs. 5 to 10). The fixing element 36 furthermore has a guide groove 72 which extends over the periphery of the fixing element 36 with interruptions. If the fixing element 36 is not fixed against rotation by the blocking element 38 as in Figs. 5 to 10, the fixing element 36 is guided along its guide groove 72 on the rotation. It can furthermore be seen from Fig. 13 that the fixing element 36 furthermore comprises a respective blocking member engagement recess 41 in axial alignment with each blocking element engagement recess 40.

Fig. 14 shows a part of the actuation apparatus 20 while masking selected components. The fixing element 36, the entrainment element carrier 32 and the handle element 24 are in particular masked here. The electric motor 50 is shown with the reduction gear 52. The latch 54 is in the closed position and is disposed beneath the abutment element carrier 34 axially along the main axis A. The abutment element carrier 34 comprises the abutment element 30 and is rotationally fixedly connected to the shaft element 22. The counter fixing element 44 is likewise rotationally fixedly connected to the shaft element 22 and comprises four spring-preloaded balls as snap-in elements 46 at its upper side (facing the fixing element 36 not shown). The blocking element 38 is substantially configured as a cylinder and extends in parallel with the main axis A. Rotational guides 74 are arranged about the counter fixing element 44 and support the fixing element 36 rotatably about the main axis A together with the guide groove 72 of the fixing element 36 of Fig. 13.

Selected components of the actuation apparatus 20 are shown in Fig. 15 to further illustrate the function of the fixing element 36. The fixing element 36 is shown with its blocking element engagement recesses 40 and blocking member engagement recesses 41. The counter fixing element 44 is visibly received in the fixing element 36. The counter fixing element 44 is rotationally fixedly connected to the shaft element 22. The counter fixing element 44 can be rotated relative to the fixing element 36 while overcoming the latching forces of the non-visible latching apparatus between the counter fixing element 44 and the fixing element 36 if the blocking member 48 of the lock cylinder 58 (cf. Fig. 1) is not, as shown here, in engagement with one of the blocking member engagement recesses 41.

The handle element 24 of Fig. 15 is likewise rotationally fixedly connected to the shaft element 22. The cylindrical blocking member 48 extends from the handle element 24 into one of the blocking member engagement recesses 41 of the fixing element 36. The blocking element 38 is in engagement in the diametrically opposed blocking element engagement recess 40. In this state, the fixing element 36 is fixed via the blocking element 38 as stationary against rotation with respect to a housing, not shown. The handle element 24 and the shaft element 22 are, in turn, fixed via the blocking member 48 against rotation relative to the fixing element 36 and are thus also fixed via the blocking element 38 as stationary against rotation relative to the housing. The blocking member 48 is brought into engagement with the respective blocking member engagement recess 41 by the lock cylinder 58 of the handle element 24 shown in Fig. 1 by a translation in parallel with the main axis A. The handle element 24 is therefore terminated in the state shown in Fig. 15 and is thus secured against manual actuation. If the blocking element 38 is, as explained, released from the engagement with the respective blocking element engagement recess 40 on an electromechanical opening actuation, the fixing element 36 can rotate along its guide groove 72 with respect to the housing. A rotation of the shaft element 22 by an electromechanical actuation is thereby nevertheless allowed even with a terminated handle element 24, that is when the blocking member 48 is in engagement with a blocking member engagement recess 41 as in Fig. 15.

An electromechanical actuation of the actuation apparatus 20 in the opening sense was explained above. An electromechanical closing actuation takes place in an analog manner, but with a reverse direction of rotation of the entrainment element carrier 32 including the entrainment elements 28. The control device of the actuation apparatus 20 in particular controls the electromechanical drive device 26 to rotate the respective entrainment element 28 in a closing rotational direction (e.g. clockwise), starting from the open position in accordance with Figs. 7 and 8 (the entrainment element 28 is at 6 o'clock, the abutment element 30 at 12 o'clock and the handle element 24 at 3 o'clock). The fixing element 36 is hereby first released for a rotational movement (in that the projection 42 is rotated out of its "12 o’clock” position in accordance with Fig. 7 and the blocking element 38 is thus released from its blocked position) and the entrainment element 28 is brought into contact with the abutment element 30. The shaft element 22 is rotated via the abutment element 30 into the closed position (the abutment element 30 is at 3 o'clock in accordance with Fig. 6) by a further rotational movement of the entrainment element 28. The control device then controls the drive device 26 to carry out a rotational movement in the reverse direction of rotation so that the respective entrainment element 28 is again released from the abutment element 30 and is rotated back into the position of rest (6 o'clock). The closed position in accordance with Figs. 5 and 6 is thus again reached for all the components. The fixing element 36 is fixed in a stationary manner again and the respective entrainment element 28 is located outside the trajectory or the total path which the associated abutment element 30 covers when a manual actuation (that is, via the handle element 24) subsequently takes place into the open position or into the tilt position.

The control device therefore generally initiates a return of the entrainment element 28 after an electromechanical actuation (that is when a target position such as the open position or the closed position has been reached) back into the position of rest which lies outside the actuation rotational range and thus outside the trajectory or total path covered by the abutment element 30.

Fig. 16 finally shows the actuation apparatus 20 in a view from below. The electromechanical drive device 26 is likewise visible from below. The latch 54 is in the closed position. A toothed wheel 78 is rotationally fixedly connected to the shaft element 22. The teeth of the toothed wheel 78 are in engagement with the respective teeth of two toothed racks 76 which are linearly guided along their longitudinal extents, with only one toothed rack also being able to be provided. The toothed wheel 78 and the toothed racks 76 form a linear drive by which the rotary movement of the shaft element 22 is converted into a translatory movement of the toothed racks 76. A respective toothed rack 76 can be coupled to an operating rod, not shown, at its end remote from the shaft element 22. Such an operating rod can e.g. be provided for actuating additional locking mechanisms, in particular a bar lock latching mechanism. For this purpose, the respective operating rod can be placed onto the door leaf or window leaf and can cooperate with a respective lock casing at the frame. Alternatively or additionally, the shaft element 22 can project beyond the actuation apparatus 20 and engage into an already present locking mechanism of the door leaf or window leaf (e.g. an integrated operating rod locking mechanism) in order to be able to actuate it.

The abutment element 30 is rotationally fixedly connected or coupled to the shaft element 22 in the embodiment shown in the Figures. Alternatively, a specific rotational clearance can also be provided between the two elements to satisfy or assist a coupling function.

In summary, a manual locking from the inside is possible with the actuation apparatus in accordance with the invention, while an electromechanical opening and closing by remote control from the outside is possible at the same time. An additional actively driven coupling for decoupling the electromechanical drive device and the shaft element is not required for this purpose; a rotary angle range which is not required for the adjustment between the closed, open and tilt positions is rather used for the necessary decoupling and coupling. For example, a terrace door comprising an actuation apparatus in accordance with the invention can be opened or closed with the aid of a remote control or a keypad even if the handle element is in the closed state. The terrace door can thereby be used as a complete side entrance door. The actuation apparatus in accordance with the invention can easily be installed without, for example, a boring of the door leaf or window leaf being necessary. It can, for example, be installed as a retrofit element at any desired doors or windows. A bar lock latching mechanism comprising a third locking point can additionally be provided. For this purpose, one or more operating rods can be provided which are driven opposite to one another, e.g. by the apparatus shown in Fig. 16 comprising a toothed wheel and at least one toothed rack. If batteries are, for example, exhausted as a source of energy or if the electromechanical drive device is defective, the operation of the actuation apparatus from the inside via the handle element remains possible. An integrated break-in notification in the actuation apparatus can additionally be provided. The electromechanical drive device represents a separate unit of the actuation apparatus in accordance with the invention which is only brought into engagement as required, whereas none of the toothed wheels of the reduction gear of the embodiment shown in the Figures move in manual operation. The electromechanical drive device is therefore decoupled from the manual drive, the handle element, in normal operation.
