Description

The invention relates to a drive device for a wing of a door, a window or the like, with a drive with a mechanical memory, which is charged by an opening movement of the wing and discharged with a closing movement of the wing, at least one electric motor, the at least one motor shaft with the wing is operatively connected and can be operated as a generator for damping the wing movements, and a control and / or regulating electronics for controlling the electric motor.

Actuators or door closers for movable door leaves with a mechanical energy storage and hydraulic damping are well known. When the door leaf is opened manually, the mechanical energy store is charged with potential energy, which closes the released door leaf again. The mechanical energy storage may, for example, comprise a spring, which is tensioned by the manual opening of the door leaf and relaxes again with the closing of the door leaf.

In most door constructions on which hydraulic door closers are mounted, danger spots occur, in particular at the secondary closing edge, at which, during the automatic closing of the door leaf by the mechanical energy store, serious injuries can occur, in particular on the fingers of a respective user. Fig. 1 The attached drawing shows a schematic representation of such danger zones in the region of secondary closing edges of doors.

The hitherto conventional hydraulic door closers have no device for securing hazardous areas or to avoid injuries to such danger zones.

In the US Pat. No. 7,571,515 Although an obstacle sensor is already described, which is connectable to the control of a hydraulically damped door closer. However, the corresponding control of such a hydraulic door closer in the presence of an obstacle is relatively complicated and usually not adaptable to the particular situation.

There are already known generator damped door closer with at least one operable as a generator electric motor whose motor shaft is operatively connected to the wing and the motor terminals can be shorted to attenuate the wing movements via a control or control electronics. In addition to a housing and a fitting for connection between the gearbox and the door, such a regenerated damped door closer usually also includes a spring acting as a mechanical reservoir. When the door is opened manually, the spring is tensioned, which loads potential energy into the spring. At the same time with the opening of the door, the gear associated with the electric motor is rotated. The at least one electric motor is usually a brushed or brushless magnetically excited DC motor. On the one hand, this generates electrical energy for the control electronics from the wing movement. On the other hand, the control electronics can dampen the movement of the door by shorting the motor windings. In particular, can be controlled or damped controlled by the relaxing spring caused closing movement of the door via the control or regulating electronics after releasing the door, which for example via a pulse width modulation of the short circuit in dependence on the current position or the current speed of the door leaf can be done. Such a regenerated damped As a rule, door leaves operate independently like a well-known hydraulically damped door closer, ie they do not require any external electrical energy source, neither via the mains nor via an accumulator.

The invention has for its object to provide a drive device of the type mentioned, in which the aforementioned disadvantages are eliminated. It should be guaranteed in the simplest possible and correspondingly cost-effective manner, in particular a reliable protection of possible danger zones in the region of the at least partially automatically operated wing.

According to the invention this object is achieved by a drive device with the features of claim 1. Preferred embodiments of the drive device according to the invention will become apparent from the dependent claims, the present description and the drawings.

The drive device according to the invention for a wing of a door, a window or the like comprises a drive with a mechanical memory, which is charged by an opening movement of the wing and discharged with a closing movement of the wing, at least one electric motor, at least one motor shaft with the wing in Active connection is and can be operated as a generator for damping the wing movements, and a control and regulating electronics for controlling the electric motor. The drive device moreover comprises a sensor system for monitoring at least one danger zone in the region of the wing. In addition, the electric motor via the control and / or regulating electronics for hedging the danger zone in response to the output signals of the sensor can be controlled.

On the basis of this design, the at least one electric motor of a generator-damped drive or door closer, which is operated as a generator for damping the blade movements, can also be used in conjunction with a sensor system for securing purposes possible danger zones are used in the region of the at least partially automatically operated wing, whereby the protection of the danger zones is ensured in a simple and reliable manner.

In this case, a secondary closing edge of a relevant door can be monitored by the sensors as the danger zone.

Alternatively or additionally, a main closing edge of a respective door can be monitored by the sensor system as the danger zone.

It is also particularly advantageous if, as a danger zone, an area lying in front of the wing during a respective opening movement and / or closing movement of the wing in the direction of movement of the wing can be monitored by the sensor system. It can also be prevented that a person is pushed through a door when opening or closing.

According to a preferred practical embodiment of the drive device according to the invention, the sensor system comprises at least one non-contact sensor and / or at least one tactile sensor.

The sensor system may include, for example, at least one active infrared light sensor, at least one safety edge, at least one active infrared sensor and / or the like.

According to an expedient practical embodiment of the drive device according to the invention, the drive is provided with at least one interface via which at least one external sensor of the sensor system can be connected and connected to the control and / or regulating electronics of the drive. A respective interface or input may be digital and / or analog.

In principle, however, such embodiments of the drive device according to the invention are conceivable in which at least one sensor of the sensor is integrated in the drive.

It is particularly advantageous if the drive is provided with at least one interface for connecting at least one sensor for a DIN left door and at least one interface for the connection of at least one sensor for a DIN right door and / or at least Includes an integrated sensor for a DIN left door and an integrated sensor for a DIN right door.

Thus, for example, two sensors, for example a sensor with a downward detection field and a sensor with an upward detection field, can be installed in a door closer for DIN left doors or DIN right doors, or the drive device can be designed in such a way that a sensor can be plugged in at the bottom or at the top. This means that one and the same regenerated damped door closer can be used both to protect danger zones in DIN-left doors and to protect hazardous areas in DIN-right doors.

According to a preferred practical embodiment of the drive device according to the invention, the functionality of the sensor system via the control and regulating electronics of the drive can be tested and / or monitored. The reliability of the protection of possible danger zones in the area of the automatically operable wing is thus increased accordingly.

The control and / or regulating electronics of the drive is preferably designed so that at a detected by the sensor danger in at least one monitored danger zone, the speed of each closing and / or opening movement of the wing by a regenerative damping via the electric motor operated as a generator at least is reduced. So can the angular velocity of the wing, for example, from 15 ° / sec to 0.5 ° / sec to minimize the risk of injury to a person in a danger zone. A preferred practical embodiment of the drive device according to the invention is characterized in that at one detected by the sensor danger in at least one monitored danger zone of the wing against the force of the mechanical memory is also determined by the control and / or control electronics of the electric motor with external electrical energy acted upon and / or a braking device for acting on a motor shaft of the electric motor can be controlled. The relevant external electrical energy can come, for example, from the network, an accumulator, a battery and / or the like.

Of particular advantage is also when a respective determination of the wing on the control and / or regulating electronics is releasable again after the sensor has signaled the elimination of the danger.

According to a further expedient practical embodiment of the drive device according to the invention, the control and / or control electronics is designed so that at a detected error of the sensor, the speed of a respective closing and / or opening movement of the wing by a regenerative damping via the electric motor operated as a generator at least is reduced until the sensors work properly again.

It is also advantageous if, in the case of a detected error, the sensor of the wing against the force of the mechanical memory is also determined by acting on the control and / or control electronics, the electric motor with external electrical energy and / or a braking device for acting on a motor shaft Electric motor can be controlled until the sensors work properly again.

Advantageously, the sensor system can be put into a sleep mode via the control and / or regulating electronics in predefinable operating phases of the drive and / or at predeterminable times. In certain operating phases or at predeterminable times, in which a hazard to persons can be practically excluded, thereby energy can be saved. For example, during the manual opening of the sash in which a mechanical energy store is recharged, the sensor system may be put into sleep mode while the sensor system is activated during automatic energy shut-off of the sash to monitor automatic closure. As mentioned above, in principle, however, a safety monitoring during a respective opening movement of the wing is possible.

It is particularly advantageous if the drive device comprises a warning device for the particular acoustic and / or optical signaling of a respective detected by the sensor danger.

A respective interface of the drive for the connection of an external sensor of the sensor system may comprise, for example, a terminal, a plug, a radio link and / or the like.

If the regenerative damped drive of the drive device is a generator-damped door closer, it can be integrated as an overhead door closer in head mounting, door leaf mounting, hinge-side mounting, on the hinge opposite side and / or the like, as integrated door closer in the door leaf, as floor-mounted door closer and / or or the like may be mounted. Particularly in the case of the assembly variant of a door leaf assembly on the opposite side of the tape, the sensor unit can be integrated in particular in the regeneratively damped drive or door closer, in which case a respective sensor can in particular comprise an active infrared sensor.

In this case, the electric motor 20 via the control and / or regulating electronics 24 to secure the danger zone in response to the output signals of the sensor 26th controllable.

The drive 14 is fastened in the present case via its housing 16, for example on the wing 12. The motor shaft 22 of the electric motor 20 is coupled via a gear 28 to an output shaft 30 of the drive 14, in the present case, for example, a sliding arm 32 is rotatably connected, which is provided at its free end with a sliding block 34 which mounted in a blind fixed Slide rail 36 is guided.

As a danger zone, for example, a secondary closing edge 38 (cf., for example, the Fig. 1 . 3 to 6 and 9 ) of a respective door monitored by the sensor 26. Alternatively or additionally, as a danger zone, for example, a main closing edge 40 (see. Fig. 9 ) of a respective door by the sensor 26 be monitored.

However, embodiments of the drive device 10 according to the invention are also conceivable, for example, in which alternatively or additionally as a danger zone a region lying in front of the wing 12 during a respective opening movement and / or closing movement of the vane 12 in the direction of movement of the vane 12 can be monitored by the sensor system 26 (see in particular again Fig. 9 ). Thus, it can also be prevented by the drive device 10 according to the invention that a person is pushed by the wing 12 during opening and / or closing and thereby injured.

In addition, the control and / or regulating electronics 24 of a respective drive 14 may in particular also be designed such that the speed of a respective closing and / or opening movement of the wing 12 by a regenerative in a detected by the sensor 26 danger in at least one monitored danger zone Attenuation via the electric motor 20 which can be operated as a generator is at least reduced. In addition, in a detected by the sensor 26 danger in at least one monitored danger zone of the wing 12 against the force of the mechanical memory 18 also be detectable or stopped by acting on the control and / or control electronics 24 of the electric motor 20 with external electrical energy and / or a braking device is actuated to act on a motor shaft 22 of the electric motor 20. In this case, a particular determination of the wing 12 via the control and / or regulating electronics 24 in particular also solvable again after the sensor 26 has signaled the elimination of the danger.

If the functionality of the sensor system 26 can be tested and / or monitored via the control and / or regulating electronics 24 of the drive 14, then the control and / or regulating electronics can also be designed such that the speed of a respective one is detected when the sensor 26 detects a fault Closing and / or opening movement of the wing 12 is at least reduced by a regenerative damping via the electric motor operated as a generator 20 until the sensor 26 again works correctly.

A corresponding embodiment is conceivable, for example, if no external electrical energy is needed. For example, when the wing 12 is opened, at which the mechanical energy store 18 is charged, the sensor system 26 can be put into a sleep mode. In contrast, the sensor 26 may be activated, for example, during a respective closing process of the wing 12 effected by the mechanical energy store 18 in order to monitor this automatic closure. In principle, however, monitoring of certain danger zones by an activated sensor 26 is also conceivable during a respective opening movement of the wing 12.
