Description

Lock drive device

Technical Field

The invention relates to a locking drive for locking and unlocking a leaf of a window, a leaf of a door or the like.

Background

Via such a locking drive device, the relevant sash or door leaf can be automatically locked and unlocked via the locking fitting associated therewith, whereby the respective operation of the locking fitting is accordingly simplified.

However, the hitherto customary locking drives of the type mentioned at the outset have the following disadvantages: after the locking or unlocking process has to be carried out relatively quickly, the movement speed of the drive device required for this must be relatively high, but this now generates a corresponding noise, which is more disturbing the faster the drive device moves.

Disclosure of Invention

The object of the present invention is to provide a locking drive of the type mentioned at the outset, by means of which it is possible to lock and unlock a window or door leaf directly and automatically in the shortest possible time with the least possible generation of noise.

According to the invention, this object is achieved by a locking drive having the features of claim 1. Preferred embodiments of the locking drive according to the invention emerge from the dependent claims, the description and the drawings.

The locking driving device for locking and unlocking a sash of a window, a door or the like according to the present invention comprises: a housing; a mechanical lockout accumulator for lockout of the fan via energy storable in the lockout accumulator; a mechanical unlocking accumulator for unlocking the fan via energy storable in the unlocking accumulator; a tensioning device which can be loaded by the fan during closing and is used for pre-tensioning the energy accumulators, wherein the tensioning device can be coupled with the energy accumulators; and a control device. The control device can trigger the release of a pretensioned locking energy store to lock the fan and the release of a pretensioned unlocking energy store to unlock the fan, and the tensioning device is connected to the energy stores via a coupling which can be operated in idle mode when the fan is open to cancel the coupling between the tensioning device and the energy stores, and via which the tensioning device and the energy stores can be coupled to one another when the fan is closed to pretension the energy stores by the closed fan.

Due to this embodiment, it is ensured by means of the locking drive that the sash or the door leaf is directly automatically locked and unlocked mechanically in a very short time, respectively, with a reduced generation of noise to a minimum. In a corresponding locking or unlocking procedure for the associated locking or unlocking of the window or door leaf, the locking fitting assigned thereto is therefore first actuated correspondingly by the mechanical energy stored in the corresponding energy accumulator. Only then is the energy accumulator pretensioned again for the subsequent locking and unlocking process by closing the door leaf or the window sash. The pretensioning of the energy store can take place without any pressure at any time, since the action requested by the user, i.e. the actual locking or unlocking, respectively, has already been carried out. For such a pre-charging of the energy accumulator, the drive device can therefore be actuated later and in particular also at a very low speed, thereby reducing the associated noise generation to a minimum. At the same time, very little waiting time is generated for the respective user after the sash or door leaf has been actually locked or unlocked in a very short time, and in particular in a time of less than one second, by means of the energy stored in the associated energy accumulator.

The locking or unlocking is thus not only simplified by automatic actuation, but also significantly accelerated, in comparison with actuation via a conventional window handle, without disturbing noise being generated.

Preferably, the locking energy store comprises a locking spring unit which can be pretensioned by the tensioning device, and/or the unlocking energy store comprises an unlocking spring unit which can be pretensioned by the tensioning device.

In this case, the actual locking or unlocking of the sash or door leaf is achieved by the energy of a locking spring unit which can be pretensioned by closing the leaf or by the energy of an unlocking spring unit which can be pretensioned by closing the leaf.

In particular, it is also advantageous if the tensioning device comprises a lever device which is acted upon by a pretensioned spring unit in the direction of the fan. By means of such a tensioning device comprising a spring-loaded lever arrangement, the locking drive apparatus can be kept relatively simple in terms of construction.

According to a preferred practical embodiment, the locking drive device comprises a slide which is connectable or connected to the locking fitting of the fan and is mounted so as to be movable between a locking position and an unlocking position, which slide can be positioned in the locking position and the unlocking position by means of a positioning device and can be acted upon by a pre-charged unlocking energy store or a pre-charged locking energy store, respectively.

The positioning device can be actuated by the control device in such a way that the carriage which occupies its locking position and is loaded by the preloaded unlocking accumulator is released in order to unlock the fan in order to be moved into its unlocking position by the energy stored in the unlocking accumulator.

In this case, the unlocking energy store or unlocking spring unit, which is released in order to move the slide into its unlocking position, is advantageously supported on one side on the slide and on the other side fixedly.

Furthermore, the positioning device can advantageously be actuated by the control device in such a way that the carriage is positioned in its unlocking position again after it has been transferred from its locking position into its unlocking position.

The positioning device can furthermore be actuated by the control device in such a way that the carriage which occupies its unlocking position and is loaded by the pretensioned locking accumulator is released in order to lock the fan in order to be moved into its locking position by the energy stored in the pretensioned locking accumulator.

In this case, the locking energy store or the locking spring unit, which is released in order to move the slide into its locking position, is advantageously supported on one side on the slide and on the other side fixedly.

furthermore, the positioning device can advantageously be actuated by the control device in such a way that the carriage is positioned in its locking position again after it has been transferred from its unlocking position into its locking position.

According to a suitable practical embodiment of the locking drive according to the invention, the locking energy store and the unlocking energy store can be pretensioned, in particular simultaneously pretensioned, by means of in particular linearly displaceable brackets or the like, which can be coupled to the tensioning device by means of a coupling.

By means of such a bow, a relatively simple holding construction of the locking drive device is also possible, by means of which in particular the locking accumulator and the unlocking accumulator can be simultaneously pretensioned.

In this case, it is preferred that after successful pretensioning of the energy accumulator and successful positioning of the bracket by the positioning device, the bracket can be decoupled from the tensioning device via the coupling which is again operated in idle mode.

It is also particularly advantageous if the locking energy store can be pretensioned via the bracket against a slide which is positioned in its unlocked position by the positioning device

The unlocking energy accumulator can be pretensioned via the bracket against the housing or a stop fixed to the housing.

It is also particularly advantageous if the carriage can be moved from its unlocked position into its locked position relative to the bracket when the bracket is positioned by the positioning device by means of a locking energy accumulator which is released and which is supported on one side on the carriage and on the other side on the positioned bracket.

It is also advantageous if the carriage can be moved from its unlocking position into its locking position by means of an unlocking energy accumulator via a bracket released by the positioning device, which unlocking energy accumulator is discharged, is supported on one side on the released bracket and on the other side on the housing or a stop fixed to the housing.

In this case, it is preferred that during the displacement of the carriage between its unlocking position and its locking position, respectively, via the bracket, the bracket is decoupled from the tensioning device by the coupling running in idle, and the locking energy store is relaxed.

According to a suitable practical embodiment of the locking drive according to the invention, the bracket is provided with two edge sections lying opposite one another, between which a slide and a locking energy store are arranged, wherein the locking energy store is arranged between one of the two edge sections and the slide and the unlocking energy store is arranged between the other edge section and the housing or a stop fixed to the housing.

The coupling provided between the energy accumulator or bow and the tensioning device may for example comprise some type of ballpoint pen mechanism.

Detailed Description

Fig. 1 to 5 show different states of an exemplary embodiment of a locking drive device 10 for locking and unlocking a leaf 12 of a window, a leaf of a door or the like according to the present invention.

The lock drive device 10 includes: a housing 14; a mechanical locking accumulator 16 for locking the fan 12 via energy storable in the locking accumulator 16; a mechanical unlocking accumulator 18 for unlocking the fan 12 via energy storable in the unlocking accumulator 18; a tensioning device 20 which can be acted upon by the closing fan 12 and which serves to pretension the energy stores 16, 18 and which can be coupled to the respective energy store 16, 18; and a control device 22.

In this case, the control device 22 can trigger the release of the pretensioned locking energy store 16 to lock the fan 12 and the control device 22 can trigger the release of the pretensioned unlocking energy store 18 to unlock the fan 12, and the tensioning device 20 is connected to the energy stores 16, 18 via a coupling 24, which can be operated in idle mode when the fan 12 is open in order to decouple the tensioning device 20 from the energy stores 16, 18, and via which the tensioning device 20 and the energy stores 16, 18 can be coupled to one another when the fan 12 is closed in order to pretension the energy stores 16, 18 by the closing fan 12.

In the present exemplary embodiment, the mechanical locking energy store 16 comprises, for example, a locking spring unit which can be pretensioned by the tensioning device 20, and/or the mechanical unlocking energy store 18 comprises an unlocking spring unit which can be pretensioned by the tensioning device 20.

The tensioning device 20 in the present case comprises, for example, a lever arrangement 28 which is acted upon by a pretensioned spring unit 26 in the direction of the fan 12.

Furthermore, the locking drive device 10 comprises a slide 30 which is connectable or connected to the locking fitting of the fan 12 and is mounted so as to be movable between a locking position (see fig. 2) and an unlocking position (see fig. 1 and 3 to 5), wherein the slide can be positioned by a positioning device 32 and can be charged by the pre-charged unlocking energy store 18 or the pre-charged locking energy store 16 (see fig. 2 in particular).

The positioning device 32 can be actuated by the control device 22 in such a way that the carriage 30, which occupies its locking position and is loaded by the preloaded unlocking accumulator 18, is released in order to unlock the fan 12 in order to be moved into its unlocking position by the energy stored in the unlocking accumulator 18 (see fig. 2 and 3).

In this case, the unlocking force store 18 or unlocking spring unit, which is released in order to move the slide 30 into its unlocking position, is supported on one side on the slide 30, while it is supported fixedly on the other side (see again fig. 2 and 3).

furthermore, the positioning device 32 can be actuated by the control device 22 in such a way that the carriage 30 is positioned in its unlocking position again after it has been transferred from its locking position into its unlocking position (see in particular fig. 3).

Furthermore, the positioning device 32 can be actuated by the control device 22 in such a way that the carriage 30, which is loaded by the pretensioned locking accumulator 16 and occupies its unlocking position, is released in order to lock the fan 12 in order to be moved into its locking position by the energy stored in the pretensioned locking accumulator 16 (see fig. 1 and 2).

In this case, the locking energy store 16 or locking spring unit, which is released in order to move the slide 30 into its locking position, is supported on one side on the slide 30 and on the other side is fixedly supported. Furthermore, the positioning device 32 can be actuated by the control device 22 in such a way that the carriage 30 is positioned in its locking position again after it has been transferred from its unlocking position into its locking position (see in particular fig. 2).

As can also be seen from fig. 1 to 5, the locking energy store 16 and the unlocking energy store 18 can be pretensioned, in particular simultaneously, for example by means of a, in particular linearly displaceable, bow 34 or the like which can be coupled to the tensioning device via the coupling 24.

After successful pretensioning of the energy stores 16, 18 and successful positioning of the bracket 34 by the positioning device 32, the bracket 34 can be decoupled from the tensioning device 20 via the coupling 24 which is again operated in idle mode (see in particular again fig. 5). As can be seen in particular again from fig. 5, the locking energy store 16 can be pretensioned via a bracket 34 against the carriage 30 which is positioned in its unlocking position by the positioning device 32.

In contrast, the unlocking energy store 18 can be pretensioned via the bracket 34 relative to the housing 14 (see in particular again fig. 5) or relative to a stop fixed to the housing.

In the present exemplary embodiment, the slide 30 can be moved in a bracket 34 positioned by the positioning device 32 from its unlocking position into its locking position relative to the bracket 34 by means of the energy-releasing locking energy store 16 which is supported on one side on the slide 30 and on the other side on the positioned bracket 34 (see fig. 1 and 2).

As can be seen from fig. 2 and 3, the carriage 30 can be moved from its unlocking position into its locking position by the unlocking energy store 18, which is released by the catch 34 released by the positioning device 32 and is supported on one side on the released catch 34 and on the other side on the housing 14 or a stop fixed thereto.

During the displacement of the carriage 30 between its unlocking position and its locking position via the bracket 34, the bracket 34 is decoupled from the tensioning device 20 by the coupling 24 running in idle, and the locking energy store 16 is relaxed.

As can also be gathered from fig. 1 to 5, the bracket 34 is provided in the present case, for example, with two edge sections 36, 38 lying opposite one another, between which the carriage 30 and the locking energy store 16 are arranged, wherein the locking energy store 16 is arranged between one of the two edge sections 36, 38, i.e. the edge section 36 and the carriage 30, and the unlocking energy store 18 is arranged between the other edge section 38 and the housing 14 or a stop fixed thereto.

The coupling 24 provided between the mechanical accumulators 16, 18 and the tensioning device 20 may for example comprise some type of ball-pen type mechanism.

In the present case, the fan 12 is, for example, a rotating fan pivotable about an axis 40.

In fig. 1 to 5, which show different states of the locking drive 10, the direction of movement of the mechanical means of the coupling is indicated by means of corresponding arrows associated with the coupling 24.

In the illustration according to fig. 1, when the fan 12 is closed, the slide 30 is positioned in its unlocking position, the locking energy store is prestressed relative to the positioned slide 30 via the positioning bracket 34, and the unlocking energy store 18 supported on the housing 14 is prestressed relative to the positioning bracket 34. In fig. 1, the positioning device 32 holds the bracket 34 in position on the left and the carriage 30 on the right.

In the illustration according to fig. 2, when the fan 12 is closed, the carriage 30 is positioned in its locking position and the locking energy store 16 is relaxed, and the unlocking energy store 18 supported on the housing 14 is prestressed relative to the positioning bracket 34.

in the illustration according to fig. 3, the carriage 30 is positioned in its unlocked position after it has been moved from its locked position into its unlocked position by the release of the unlocking energy accumulator 18 via the release bow 34, while the fan 12 is always closed. Thus, the unlock accumulator 18 releases energy. After the corresponding displacement of the bracket 34 with the carriage 30, with the coupling running in idle mode and the tensioning device 20 decoupled therefrom, the locking energy store 16 remains in its discharged state.

Fig. 4 shows the locking drive 10 with the leaf open and the tensioning device 20, which is spring-loaded by the spring unit 26 in the direction of the open leaf 12 and which latches into the coupling 24 again. In this case, the slide 30 is positioned in its unlocked position, without both the locking energy store 16 and the locking energy store 18 respectively releasing energy or slack.

Finally, fig. 5 shows the locking drive 10 and the energy stores 16, 18 preloaded by the closed fan 12 when the fan 12 is closed again. In this case, the carriage 30 is again positioned in its unlocking position, while the locking energy store 16 is prestressed relative to the positioned carriage 30 via the positioning bracket 34, and the unlocking energy store 18 supported on the housing 14 is prestressed relative to the positioning bracket 34, so that the locking drive device again assumes its initial state, which is already shown in fig. 1. In the case of the tensioning device 20 which is loaded by the closing fan 12 to pretension the energy accumulators 16, 18, the tensioning device is coupled to the released bracket 34 via the coupling 24, and once the positioning device 32 is engaged, i.e. the bracket 34 has been repositioned by the positioning device 32 with the energy accumulators 16, 18 tensioned, the tensioning device is decoupled again.

With the locking drive device 10 according to the invention it is ensured that locking and unlocking, respectively, take place in a very short time with a minimum of noise generation. In a corresponding locking or unlocking procedure for the associated locking or unlocking of the window or door leaf 12, the locking fitting assigned thereto is therefore first actuated by the energy stored in the corresponding energy accumulator. Only then is the energy accumulator required for further locking or unlocking pre-charged again by subsequently closing the fan 12.
