A detector is designed to detect whether the blocking element is occupying the blocking position, the drive being designed such that activation of the drive unit is prevented if the detector detects the blocking position of the blocking element.

Description

DRIVE

The invention relates to a drive for a sash of a window or a door, with a housing, an electromotive drive unit for operating the sash and an electronic control unit for activating the electromotive drive unit. The invention also relates to a window or a door with such a drive.

Drives of the type mentioned are generally known. After the sash of the window or door can be automatically operated via their electric motor drive unit, they bring a correspondingly higher level of convenience when operating the window or door. Access protection can be provided, which ensures that only authorized persons can operate the drive and thus open, pivot and / or close the window or door. In the event of a malfunction of the electronic control unit or its software, however, there is now the risk that the electromotive drive unit can be activated immediately and thus the wing can be operated.

The invention is based on the object of specifying a drive of the type mentioned at the outset, with which the above-mentioned problem is eliminated. It should be ensured in the simplest possible way, even in the event of a malfunction of the electronic control unit or its software, that actuation of the drive and thus of the window or door is only possible with the appropriate authorization. A corresponding window or door should also be specified.

According to the invention, this object is achieved by a drive with the features of claim 1. Preferred embodiments of the invention drive result from the subclaims, the description and the drawing.

The drive according to the invention for a wing of a window or a door comprises a housing, an electromotive drive unit for actuating the wing and an electronic control unit for activating the electromotive drive unit. A blocking element is provided which can be displaced between egg ner blocking position in which actuation of the wing is mechanically prevented by blocking the electromotive drive unit, and a release position in which the electromotive drive unit is mechanically released to actuate the wing. There is also an adjustable between egg nem locked state and an unlocked Verriege treatment device is provided, which holds the blocking element in the blocked position in the locked state and in the unlocked state allows a shifting of the blocking element from the blocking position into the release position, the locking device has an access protection so that Locking device can only be adjusted from the locking state to the unlocked state with a given access authorization. In addition, a detector is provided which is connected to the electronic control unit and which is designed to detect whether the blocking element is in its blocking position, the drive being designed in such a way that the electromotive drive unit is not activated when the de detector detects the blocking position of the blocking element.

Due to this design, the drive remains secured by mechanical protection even in the event of a malfunction of the electronic control unit or its software. The protection according to the invention is not only inexpensive, it can also be retrofitted without any problems. If the blocking element assumes its blocking position, this is reported on the one hand via the detector to the electronic control unit, which then prevents the user actuates the drive and thus the window or door. In addition, the actuation of the electromotive drive unit is not mechanically possible in the water position of the blocking element. If the blocking element is moved into its release position, this is reported accordingly by the detector to the electronic control unit, so that the electronic control unit now allows the user to operate the drive. In order to move the blocking element into its release position, it is first neces sary to adjust the locking device in its unlocked state. However, due to the access security, this adjustment can only be made if the access authorization is available.

The access security preferably comprises a mechanical locking system that can be actuated by a key, in particular a lock cylinder. Access authorization can be easily verified and implemented in a functionally reliable manner using a key. In principle, however, another type of access security or another type of proof of access authorization is also possible.

The locking device preferably comprises a locking section which, in the locked state, engages positively in an engagement receptacle of the housin ses, in particular a base plate of the housing, the engagement being released in the unlocked state. The locking of the locking device is then a lock with respect to the housing of the drive.

Preferably, the locking device can be adjusted between the locked state and the unlocked state by rotating about an axis of rotation that extends in particular parallel to a longitudinal axis of the drive. This is particularly advantageous if the access security is provided by a key that is operated by turning. It is preferable added when the locking portion extends transversely, in particular perpendicularly, to the axis of rotation and is pivoted into the aforementioned engagement receptacle of the housing when rotating the locking device.

According to a preferred embodiment it is provided that the locking device and the blocking element are rotatably coupled to one another around the displacement direction of the blocking element. Alternatively or additionally, it can be provided that the locking device and the blocking element are firmly coupled to one another in the unlocking state in the displacement direction of the blocking element. In principle, it is also possible that the locking device and the blocking element are additionally coupled firmly to one another in the locking state in the displacement direction of the blocking element.

In addition, it is preferred if the locking device comprises a coupling section which, in the unlocked state, engages positively in an engagement receptacle of the blocking element. Accordingly, it is also possible here for the coupling section to additionally engage positively in the engagement receptacle of the blocking element in the locked state.

According to a preferred embodiment of the invention, the locking device is integrated in a cap, in particular an end cap, inserted into the housing at the end face. This is particularly advantageous if the cap and locking device can be pulled out of the housing together with the blocking element when the locking device is in its unlocked state and the locking device is prevented from being pulled out of the housing when the locking device is in its locked state. It is preferred if the pulled-out position of the cap corresponds to the release position of the blocking element, the detector being designed to close to the electronic control unit in the pulled-out position of the cap transmit that the blocking element no longer assumes its blocking position, so that activation of the electromotive drive unit is released.

The detector can be designed as a pushbutton which can be actuated by moving the blocking element. Such a detector is inexpensive and functionally reliable. In particular, the button can be mounted on the blocking element, the button being actuated in the blocking position of the blocking element by resting on the housing and / or being unactuated outside the housing in the release position of the blocking element.

It is particularly advantageous if means for monitoring the current consumption of the electromotive drive unit are provided and the electronic control unit is designed to interrupt activation of the electromotive drive unit as soon as the current consumption exceeds a predeterminable value. If the electromotive drive unit or a gear thereof is blocked by the blocking element occupying its blocking position, the power consumption increases if the electromotive drive unit is activated by the electronic control unit. As soon as this exceeds the predefinable value, the activation of the electromotive drive unit is interrupted by the electronic control unit.

According to a preferred practical embodiment of the drive according to the invention, the electromotive drive unit comprises a spindle gear driven by means of an electric motor with a spindle and a spindle nut, via which the wing can be actuated. In particular, it can be provided that the spindle nut of the spindle gear of the electromotive drive unit can be blocked by the blocking element in its blocking position to mechanically prevent actuation of the wing, and the spindle nut can be released by moving the blocking element into its release position. Instead of the spindle gear, however, any other type of gear such as a chain gear or the like can be provided.

In order to activate the electromotive drive unit by the electronic control unit, an input device connected to the electronic control unit and having a manually operable operating element is preferably provided. If the blocking element is in its blocking position, the electromotive drive unit is activated, however, as explained above.

In particular, the control element can be activated depending on whether the detector detects the blocking position of the blocking element. It can therefore be provided that the control element is not active at all, i.e. cannot be operated effectively at all as long as the blocking element is in the blocking position. In this context, it can also be provided that the operating element can be backlit depending on whether the detector detects the blocking position of the blocking element. It can therefore be provided that the operating element is not visible at all as long as the blocking element is in the blocking position.

The input device can also comprise several control elements that together form a control panel, the several control elements being activated and / or backlit differently via the electronic control unit depending on a respective position of the aforementioned spindle nut of the aforementioned spindle gear of the electromotive drive unit. As a result, the rotary position of the wing operated by the drive can be read off, and the drive can be operated particularly intuitively.

According to a further advantageous embodiment of the drive according to the invention, means for automatic detection of proximity and / or brightness are provided provided to activate the input device. The means for proximity detection can include at least one capacitive sensor with a capacitive measuring field, the electronic control unit being designed to monitor changes in the capacitive measuring field that occur when a user approaches.

The housing is preferably designed at the same time as a handle for manual operation of the wing. The housing advantageously has a rounded shape in cross section to form an undercut.

In addition, the housing can have a base plate on which the other constituent parts of the drive are mounted, and a hood that serves as a protective cover for the drive to have.

The window according to the invention or the door according to the invention are characterized in that it or they are provided with a drive according to the invention.

1 to 8 show a schematic representation of an exemplary Ausfüh approximate form of a drive 10 according to the invention for a sash of a window or a door. The drive 10 comprises a housing 12, an electromotive drive unit 14 to open or close the wing, and an electronic control unit 16 to activate the electromotive drive unit 14, in particular to energize it.

In addition, the drive 10 is provided with a blocking element 20 which, relative to the housing 12, mechanically prevents between a blocking position in which an actuation of the wing by blocking the electromotive drive unit 14 is (see. Fig. 2, 5 and 6), and a release position in which the blocking element 20 is pulled out of the housing 10, as explained in more detail below, so that the electromotive drive unit 14 for actuating the wing is mechanically released is (see. Fig. 4 and 7), is displaceable.

As can be seen from Fig. 2, the electromotive drive unit 14 in the present case comprises a spindle gear driven by an electric motor 30 with a spindle 32 and a spindle nut 34. When the Blockadeele element 20 is in its blocking position, the spindle nut 34 of the spindle transmission of the electromotive drive unit 14 is mechanically blocked and cannot be operated. In contrast, the spindle nut 34 is released when the blocking element 20 is moved into its release position.

In addition, a locking device 18 is provided, which can be adjusted between a locked state (see FIG. 5) and an unlocked state (see FIGS. 3 and 4). The locking device 18 is coupled to the blockade element 20 in such a way that it can be pulled out of the housing 10 together with the blockade element 20 in the unlocked state. In the locked state, however, the locking device 18 and thus the blocking element 20 cannot be pulled out of the housing 10, so that the blocking element 20 is held in the blocking position.

The adjustment between the two states is carried out by rotating the locking device 18 about an axis of rotation which extends parallel to a longitudinal axis of the drive 10. In particular, the locking device 18 has a locking section 52 (see FIG. 5) which extends transversely, in particular perpendicularly, to the axis of rotation. When the locking device 18 is rotated from the unlocked state into the locked state, the locking section 52 is pivoted into an engagement receptacle 60 in a base plate 26 of the housing 12 and engages there in a form-fitting manner around the Establish locking state. In the unlocked state, however, the locking portion 52 is out of engagement with the engagement receptacle 60, so that the pulling out explained above is possible.

For coupling with the blocking element 20, the locking device 18 has a coupling section 62 which, in the unlocked state, engages positively in an engagement receptacle 64 of the blocking element 20, as can be seen in particular from FIGS. 4, 6 and 7. Via the coupling section 62 and the engagement receptacle 64, the locking device 18 and the blocking element 20 are rotatably coupled to one another around the displacement direction of the blocking element 20 and are firmly coupled to one another in the unlocked state in the displacement direction of the blocking element 20.

As can be seen in particular from FIG. 3, the locking device 18 is integrated into an end cap 28, which is inserted into the housing 12 at the end in the direction of displacement of the blocking element 20. When the locking device 18 is in the unlocked state, the end cap 28 can be pulled out of the housing 10 together with the locking device 18 and the blocking element 20. The pulled-out position of the end cap 28 corresponds to the release position of the blocking element 20. If the locking device 18 is in the locked state, this is not possible due to the positive engagement of the locking portion 52 in the engagement receptacle 60.

The locking device 18 is provided with an access lock 58, so that the locking device 18 can only be adjusted from the locked state to the unlocked state if access authorization is available. In the present case, the access security 58 consists of a lock cylinder 58 which can be actuated by a key. Thus, only a user who has the key can unlock the locking device 18. Without a key, it is not possible to operate the drive 10 and to pivot the leaf in the opening or closing direction. If a user is not authorized, the positive fit with the housing 12 or the base plate 26 brought about by the locking section 52 of the locking device 18 is maintained. The end cap 28 and the blocking slide 20 occupying its blocking position cannot be pulled out of the housing 12, ie actuation of the wing is mechanically prevented by blocking the motorized drive unit 14.

In addition, the drive 10 has a detector 22 which is connected to the electronic control unit 16 and is used to detect whether the blocking element 20 is in its blocking position. If this is the case, provision is made for the electromotive drive unit 14 not to be activated. The activation of the electromotive drive unit 14 is thus not only secured mechanically via the form fit explained above, but also electrically via a detector signal. If the end cap 28 is in its pulled-out position and thus the blocking element 20 is no longer a blocking position, the detector 22 reports this to the electronic control unit 16 so that activation of the electromotive drive unit 14 is basically enabled.

In the present case, the detector 22 is designed as a button 22 which can be actuated by the displacement of the blocking element 20 and which is mounted on the blocking element 20. If the blocking element 20 assumes its blocking position, the button 22 is pressed or actuated by the housing 12 (cf. FIG. 6). If, on the other hand, the blocking element 20 assumes its release position, the button 22 lies outside the housing 12 (see FIG. 7) and is no longer pressed. In addition, means for monitoring the power consumption of the electric motor drive unit 14 can be provided. In this case, activation of the electromotive drive unit 14 by the electronic control unit 16 can be interrupted as soon as the current consumption exceeds a predeterminable value. If the electromotive drive unit 14 is blocked with the locking device 18 and its blocking position occupying the blocking element 20 by the positive fit of the locking section 52 of the locking device 18 with the housing 12 or the base plate 26, the current consumption of the electromotive drive unit 14 inevitably increases. As soon as this exceeds the predetermined value, the control of the drive unit 14 is interrupted by the electronic control unit 16.

The drive 10 is provided with a manually operated control panel 24 for its control by a user (cf. FIGS. 1 and 8). The control panel 24 can comprise several control elements such as buttons or the like, which can be activated and / or backlit differently via the electronic control unit 16 depending on the respective position of the spindle nut 34 of the spindle gear of the electromotive drive unit 14. It is provided that at least one control element of the control panel 24 can be activated and / or backlit as a function of a respective actuation or non-actuation of the button 22.

In addition, the drive 10 can have means for automatic proximity and / or flush detection in the area of the control panel 24 in order to activate the control panel 24 used for user control. The means for proximity detection can include means for monitoring changes in a capacitive measuring field generated in the area of the control panel 24 when a user approaches. As can be seen in particular from FIGS. 1 and 2, the drive 10 can also ei NEN with the electronic control unit 16 connected path meter 36 for detecting the opening state of the sash and a via the electronic control unit 16 controllable display device 38 to show the opening state of the wing.

A chassis 44 can be assigned to the electric motor 30. The electronic control unit 16 can be arranged on a control circuit board 46 which is mounted in the housing 12 via a holder 48. The control panel 24 can be introduced into the housing 12 via a holder 50.

As can be seen in particular from FIGS. 8 and 9, the housing 12 of the drive 10 can also be designed as a handle for manual operation of the wing. In this case, the housing 12 has a rounded shape in cross section to form a back section. 9 shows an exemplary window 54 according to the invention with a drive 10, as is described with reference to FIGS. 1 to 8. The drive 10, which simultaneously serves as a handle, is provided on a sash 56 of the window 54 in the present case.

The drive 10 according to the invention ensures redundant protection via the software of the electronic control unit 16 and via the mechanics. It can also be retrofitted without any problems. Intuitive operation of the drive 10 is possible with the backlighting of operable buttons on the control panel 24. With the housing 12 of the drive 10, which also serves as a handle, the additional handle previously required for manual operation on the window sash is no longer necessary.
