Description

Locking drive device

Technical Field

The invention relates to a locking drive for locking and unlocking a wing of a window, door or the like by means of a motorized drive unit.

Background

Via such a locking drive, the relevant sash or door leaf can be automatically locked and unlocked via the locking fitting associated therewith, whereby corresponding manipulation of the locking fitting is correspondingly simplified.

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

Disclosure of Invention

The object on which the invention is based 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, while producing as little noise as possible.

According to the invention, this object is achieved by a lock 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 wing of a window, door, etc. according to the present invention comprises: a motorized drive unit; a locking energy store, in particular of the mechanical type, which can be preloaded via a motorized drive unit and which can be coupled to a locking fitting assigned to the wing for locking the wing; an unlocking energy store, in particular mechanical, which can be preloaded via a motorized drive unit and which can be coupled to the locking fitting for unlocking the wing; and a control device. In this case, the motorized drive unit can be actuated via the control device and the unloading of the respective preloaded energy store can be triggered such that, in order to lock the wing with the energy stored in the preloaded locking energy store when the motorized drive unit is stopped, the unloading of the preloaded locking energy store is first triggered and, after successful locking, the unlocking energy store is only preloaded by the motorized drive unit, and, in order to unlock the wing with the energy stored in the preloaded unlocking energy store when the motorized drive unit is stopped, the unloading of the preloaded unlocking energy store is first triggered and, after successful unlocking, the locking energy store is only preloaded by the motorized drive unit.

Due to this embodiment, a direct automatic locking and unlocking of the window or door leaf in a very short time is ensured by the locking drive, respectively, while the noise generated is reduced to a minimum. In a corresponding locking or unlocking procedure for the associated locking or unlocking of a sash or door leaf, the locking fitting assigned to the sash or door leaf is therefore first actuated correspondingly by the energy stored in the respective energy accumulator. Only then is the additional energy store, which is later required for unlocking or locking, reloaded by the motorized drive unit by the motorized drive. The preloading of the further energy store can take place without any time pressure, since the action respectively requested by the user, i.e. the actual locking or unlocking, has already been performed. For such a preloading of the respective energy store, the motorized drive unit can therefore be operated at a very low speed, whereby the noise generated in this connection is reduced to a minimum. At the same time, for the respective user, very little waiting time results after the sash or door leaf has actually been 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 relevant energy store.

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

Preferably, the locking energy store comprises a locking spring unit which can be prestressed by means of a motorized drive unit and/or the unlocking energy store comprises an unlocking spring unit which can be prestressed by means of a motorized drive unit.

In this case, the actual locking or unlocking of the window/door leaf is achieved by the energy of a locking spring unit which can be prestressed by the motorized drive unit or by the energy of an unlocking spring unit which can be prestressed by the motorized drive unit.

It is also particularly advantageous if the motorized drive unit comprises a linear drive.

By means of such a linear drive, the respective mechanical energy store or spring unit can be preloaded by means of a linear movement of the drive, whereby the locking drive can be kept relatively simple in terms of construction.

According to a preferred practical embodiment, the locking drive comprises a slide which is connectable or connected to the locking fitting and is mounted so as to be movable between a locking position and an unlocking position, in which the slide is lockable by the locking device and can be acted upon by the preloaded unlocking energy store or the preloaded locking energy store, respectively.

As soon as the slide is locked in the locked or unlocked position after successful locking or unlocking, the energy store required for the subsequent unlocking or locking process can therefore be preloaded or prestressed by the motorized drive unit.

The locking device can be preferably actuated by the control device in such a way that the slide, which occupies its locking position and is loaded by the preloaded unlocking energy store, is released to unlock the wing, so that it is moved into its unlocking position by the unloaded unlocking energy store when the motorized drive unit is stopped.

In this case, the unlocking energy store or the unlocking spring unit, which is unloaded in order to move the slide into its unlocking position, is advantageously supported on the one hand on the slide and on the other hand is fixedly supported when the motorized drive unit is at a standstill.

Furthermore, the locking device can be advantageously actuated by the control device in such a way that the slide is locked again in its unlocked position after it has been rotated from its locked position into its unlocked position.

The motorized drive unit can be controlled by the control unit such that it preloads the locking energy store again after the slide has been rotated into its unlocked position and after successful locking into this unlocked position, in order to load the slide.

The locking device can furthermore be actuated by the control device such that the slide loaded by the preloaded locking energy store, which occupies its unlocked position, is released to lock the wing, so that it is moved into its locked position by the unloaded locking energy store when the motorized drive unit is stopped.

Advantageously, the locking energy store or the locking spring unit unloaded for moving the slide into its locking position is supported on the one hand on the slide and on the other hand is fixedly supported when the motorized drive unit is stopped.

Advantageously, the locking device can be actuated by the control device in such a way that the slide is locked again in its locking position after it has been rotated from its unlocking position into its locking position.

The motorized drive unit can be controlled by the control device such that it preloads the unlocking energy store again after the slide has been rotated into its locking position and after successful locking in this locking position, in order to load the slide.

According to a practical embodiment of the locking drive according to the invention, the locking energy store and the unlocking energy store can each be prestressed against the locking slide via a clamping bracket or the like which can be moved in a linear manner, in particular by a motorized drive unit.

By means of such a clamp, the locking and unlocking energy store can be loaded or prestressed by the motorized drive unit, and a relatively simple holding configuration of the locking drive is achieved.

In this case, it is preferred that the slide can be moved from its locked position into its unlocked position relative to the locked bracket by means of a relieved unlocking energy store which is supported on the one hand on the slide and on the other hand on the locked bracket when the motorized drive unit is stopped and in particular the bracket is locked by the locking device, and can be moved from its unlocked position into its locked position relative to the locked bracket by means of a relieved locking energy store which is supported on the one hand on the slide and on the other hand on the locked bracket.

It is particularly advantageous if the bracket is provided with two edge sections lying opposite one another, between which an unlocking energy store, in particular a locking energy store, comprising an unlocking spring unit, in particular a locking spring unit, and a slide lying therebetween are arranged, wherein the unlocking energy store is supported by its end facing away from the slide on one of the two edge sections and is in particular fixedly connected thereto, and the locking energy store is supported by its end facing away from the slide on the other edge section and is in particular fixedly connected thereto.

Detailed Description

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

The lock drive device 10 includes: a motorized drive unit 12; a locking energy store 14, in particular a mechanical locking energy store, such as a locking spring unit, which can be preloaded via the motorized drive unit 12 and can be coupled to a locking fitting assigned to it for locking the wing; an unlocking energy store 16, in particular of a mechanical type, which can be preloaded via the motorized drive unit 12, in the present case, for example, an unlocking spring unit, which can be coupled to the locking fitting for unlocking the wing; and a control device 18.

Via the control device 18, the motorized drive unit 12 can be actuated, and the unloading of the respective preloaded energy stores 14, 16 or spring units can be triggered, so that in order to lock the wing with the energy stored in the preloaded locking energy store 14 when the motorized drive unit 12 is stopped, the unloading of the preloaded locking energy store 14 is first triggered and the unlocking of the energy store 16 is only preloaded by the motorized drive unit 12 after successful locking (see in particular figures 3 to 5), and in order to unlock the wing leaf by means of the energy stored in the preloaded unlocking energy store 16 when the motorized drive unit 12 is stopped, the unloading of the preloaded unlocking energy store is first triggered and the locking energy store is only preloaded by the motorized drive unit 12 after successful unlocking (see in particular fig. 1 to 3).

as already detailed, in the present exemplary embodiment, the locking energy store 14 comprises a locking spring unit which can be prestressed by the motorized drive unit 12, and/or the unlocking energy store 16 comprises an unlocking spring unit which can be prestressed by the motorized drive unit 12.

The drive unit 12 in the present case comprises, for example, a linear drive.

Furthermore, the locking drive 10 comprises a slide 20 which is connectable or connected to the locking fitting of the associated window or door leaf and which is mounted so as to be movable between a locking position (see fig. 1, 4 and 5) and an unlocking position (see fig. 2 and 3), in which it is lockable by the locking device and loadable by the preloaded unlocking energy store 16 or the preloaded locking energy store 14, respectively.

The locking device 22 can be actuated by the control device 18 in such a way that the slide 20, which is loaded by the preloaded unlocking energy store 16 and occupies its locking position, is released to unlock the wing, so that it is moved into its unlocking position by the unloaded unlocking energy store 16 when the motorized drive unit 12 is stopped (see in particular fig. 1 and 2).

In this case, the unlocking energy store 16 or the unlocking spring unit, which is unloaded in order to move the slide 20 into its unlocking position, is supported on the one hand on the slide 20 and on the other hand is fixedly supported when the motorized drive unit 12 is at a standstill (see in particular again fig. 1 and 2).

Furthermore, the locking device 22 can be actuated by the control device 18 in such a way that the slide 20 is locked again in its unlocked position after it has been rotated from its locked position into its unlocked position (see in particular fig. 2).

The motorized drive unit 12 can be actuated by the control device 18 in such a way that it preloads the locking energy store 14 again to load the slide 20 after the slide 20 has been rotated into its unlocked position and after successful locking into the unlocked position (see in particular fig. 2 and 3).

Furthermore, the locking device 22 can be actuated by the control device 18 in such a way that the slide 20, which is loaded by the preloaded locking energy store 14 and occupies its unlocked position, is released to lock the wing, so that it is moved into its locked position by the unloaded locking energy store 14 when the motorized drive unit 12 is stopped (see in particular fig. 3 and 4).

The locking energy store 14 or the locking spring unit, which is unloaded in order to move the slide 20 into its locking position, is supported on the one hand on the slide 20 and on the other hand is fixedly supported when the motorized drive unit 12 is at a standstill.

Furthermore, the locking device 22 can be actuated by the control device 18 in such a way that the slide 20 is locked again in its locking position after it has been rotated from its unlocking position into its locking position (see in particular fig. 4).

the motorized drive unit 12 can be actuated by the control device 18 in such a way that it unlocks the energy store 16 after the slide 20 has been rotated into its locking position and after successful locking in this locking position, it is reloaded again in order to load the slide 20 (see in particular fig. 4 and 5).

As can be seen from fig. 1 to 5, the locking energy store 14 and the unlocking energy store 16 can each be prestressed against the locked slide 20, for example, by means of a bracket 24 or the like which is movable, in particular linearly, by the motorized drive unit 12.

In this case, when the motorized drive unit 12 is at a standstill and in particular the bracket 24 is locked by the locking device 22, the slide 20 can be moved from its locked position into its unlocked position relative to the locked bracket 24 by means of the unloaded unlocking energy store 16 which is supported on the one hand at the slide 20 and on the other hand at the locked bracket 24 (see in particular fig. 1 and 2), and from its unlocked position into its locked position relative to the locked bracket 24 by means of the unloaded locking energy store 14 which is supported on the one hand at the slide 20 and on the other hand at the locked bracket 24 (see in particular fig. 3 and 4).

As can be further seen from fig. 1 to 5, the bracket 24 is provided in the present case, for example, with two edge sections 26, 28 lying opposite one another, between which an unlocking energy store 16, in particular comprising an unlocking spring unit, and in particular a locking energy store 14, in particular comprising a locking spring unit, and a slide 20 lying therebetween are arranged. The unlocking energy store 16 is supported by its end facing away from the slide 20 on one of the two edge sections 26 and is in particular fixedly connected thereto, and the locking energy store 14 is supported by its end facing away from the slide 20 on the other edge section 28 and is in particular fixedly connected thereto.

The locking drive has a housing 30 in which the motorized drive unit 12, the energy storage 14, 16, the slide 20 and the bracket 24 are arranged. The control device 18 can likewise be arranged within the housing 30 or also outside the housing 30.

Fig. 1 to 5 show various states of the locking drive 10, whereby the direction of movement of the motorized drive is indicated by means of corresponding arrows associated with the motorized drive unit 12.

In the illustration according to fig. 1, the slide 20 is locked in its locked position, the unlocking energy store 16 or the unlocking spring unit preloads or prestresses the slide 20, and the locking energy store 14 or the locking spring unit is unloaded or unloaded.

In the illustration according to fig. 2, the slide 20 is locked in its unlocking position and the unlocking energy store 16 or the unlocking spring unit and the locking energy store 14 or the locking spring unit are unloaded or unloaded, respectively.

In the illustration according to fig. 3, the slide 20 is locked in its unlocked position, and the locking energy store 14 or the locking spring unit is preloaded or prestressed by the motorized drive unit 12 against the locked slide 20.

In the illustration according to fig. 4, the slide 20 is locked in its locking position, while the unlocking energy store 16 or the unlocking spring unit and the locking energy store 14 or the locking spring unit are unloaded or unloaded, respectively.

In the illustration according to fig. 5, the slide 20 is locked in its locking position, while the unlocking energy store 16 or the unlocking spring unit is prestressed against the locked slide 20 by the motorized drive unit 12, and the locking drive 10 then assumes its initial state, which is already shown in fig. 1, again.

The locking and unlocking in each case in a very short time is ensured by means of the locking drive 10 according to the invention, while the noise generated is reduced to a minimum. In a corresponding locking or unlocking procedure for the relevant locking or unlocking of the sash or door leaf, the locking fitting associated therewith is therefore first actuated by the energy stored in the respective energy store. Only then is the energy store, which is later required for unlocking or locking, reloaded by the motorized drive unit 12.
