Description

The invention relates to a drive system for a gate.

Such a drive system is generally used to operate a gate with which an opening of a building can be closed. In particular, the door can be designed as a garage door, in particular as a sectional door.

With such a drive system, a gate can be automatically actuated, on the one hand to obtain access to the building by opening the door and on the other hand to prevent access to the building by closing the gate.

Nevertheless, the gate does not provide sufficient burglary protection, since there is a general risk of mechanical levering of the door. Namely, the electric drive typically has only insufficient self-locking, so that a burglar against the resistance of the electric drive can postpone the gate and thus gain access to the building.

On the other hand, there is a problem that moisture can not escape through tightly closing the door in the building, so that mold can form inside the building.

The WO 2012/156154 A1 relates to a door with a drive system for driving a door leaf, with which a door opening can be closed, wherein by means of the drive system, the door leaf between different target positions is movable, and wherein in a desired position a ventilation function is realized in that the door leaf does not completely close the door opening but a ventilation slot between the lower edge of the door leaf and a leaves the door opening bounding ground. Furthermore, an environmental parameter-detecting sensor is provided, wherein in dependence on sensor signals generated by the sensor, the door leaf is actuated.

The DE 20 2006 013 676 U1 relates to a gate, in particular a sectional door, with a door leaf which can be moved by means of a drive from an open end position to a closed end position, and with a control unit for controlling the drive. The control unit has a ventilation control device for targeted, in particular automatic control of the drive in such a way that the drive moves the door leaf into a predetermined ventilation position located between the open end position and the closed end position. Furthermore, a locking device is provided with which the door leaf can be secured in the ventilation position. This locking device comprises a locking device with a rotary seal, which can be brought into engagement with a stationary stop.

The invention has for its object to provide a drive system which has high functionality with low design effort.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

The invention relates to a drive system for a gate closing an opening of a building, with a drive unit having an electric drive. By means of the drive system, the door can be moved between an open position and a closed position. The door can still be moved into a ventilation position, in which the door leaves only one ventilation slot at the opening of the building. In the ventilation position and / or in the closed position, the door is secured against manual opening characterized in that a locking element blocks the electric drive, that the locking element between an unlocked position and a locking position is movable, wherein only in the locking position, the locking element blocks the electric drive, and that the electric drive is thereby blocked. The locking element is in its locking position on a connected to the rotor of the electric drive stop.

The basic idea of the invention is thus to design the closing function of the door in such a way that it achieves an increased functionality of the drive system, in particular with regard to safety aspects.

A first aspect of the present invention is to provide anti-burglary protection which is achieved in a simple and efficient manner by a locking element blocking the electric drive.

A significant advantage of the invention is that the locking element can be directly engaged with an element on the electric drive, so as to block the electric drive itself. The locking element is designed so stable that it can block the electric drive to its self-destruction. This ensures an effective mechanical locking of the door, so that unauthorized pushing can be safely avoided. In particular, such a certified anti-burglary protection can be realized in such a way that the electric drive blocked by the locking element can withstand forces of more than 300 kg.

According to the invention, the locking element is movable between an unlocking position and a locking position, wherein the locking element blocks the electric drive only in the locking position.

In this case, the electric drive is blocked by the fact that the locking element rests in its locking position on a connected to the rotor of the electric drive stop.

A significant advantage of the thus formed locking mechanism is that blocked by a suitable control of the movement of the locking element of the electric drive at any times and thus the door can be secured at any position. Thus, depending on the application, the door can be secured either in its closed position or in a freely dimensionable ventilation position by blocking the electric drive by means of the locking element.

According to a structurally advantageous embodiment of the invention, the locking element has a lifting magnet.

The locking element associated stop is formed by a co-rotating with the rotor of the electric drive stop disc.

The thus formed locking mechanism has a structurally simple construction and also ensures a secure locking of the electric drive.

According to a further aspect of the invention, the gate can be controlled by a sensor between a closed position in which the door completely closes the building opening, and a ventilation position in which the door still leaves a ventilation slot open.

This can be easily prevented mold growth within the building. This device according to the invention is in particular Can be used for garages, as there are often retracted wet or covered with snow motor vehicles, which lead to increased moisture formation, so there is an increased risk of mold growth.

Advantageously, the electric drive is arranged on a carriage, which is coupled to the door and can be moved for closing and opening on a guide rail, wherein the sensor is arranged on the carriage.

The sensor control generally works in such a way that when a high level of humidity is detected in the building by means of the sensor, the door is moved from the closed position to the ventilation position.

Advantageously, the door is moved from the ventilation position into the closed position when the humidity measured with the sensor falls below the threshold value.

In contrast, the door is moved from the closed position to the ventilation position when the humidity measured with the sensor exceeds a threshold value.

Thus, if in the building, especially in the garage, no increased humidity is detected with the sensor, the door is held in the closed position, that is, the door then closes the building opening completely. If, on the other hand, a moisture level above the threshold is registered, the door is automatically moved from the closed position to the ventilation position, so that moisture is removed from the building to the outside via the ventilation slot. As soon as the humidity in the building is below the threshold value, the door is moved back into the closed position.

This control can be extended to the effect that the moved into the ventilation position gate is returned to the closed position. With the sensor, a further increase in the humidity beyond the threshold for a certain time or over another, above registers the threshold value of the second threshold. After a predetermined period of time, the gate is returned to the ventilation position.

This covers the case where, for example, due to heavy rain, the humidity outside the building is greater than the humidity inside the building. In this case, moving the door from the closed position to the ventilation position is counterproductive, since moisture is not carried out from the building via the ventilation position, but additional moisture penetrates into it. Therefore, when registering a rise in humidity, the door is again moved from the ventilation position to the closed position and only after a certain period of time, which can be several hours, move the door back to the ventilation position.

According to an advantageous embodiment of the invention, the drive system has at least one visible directional rays emitting transmitting element. By means of which at least one desired position for at least one object to be positioned in the building is displayed.

In this case, a door of a garage is particularly advantageously actuated with the drive system. With the directional beams of the or a transmitting element, the parking position of a motor vehicle is displayed as a target position.

The transmission element controlled by the drive system thus creates a considerable additional benefit for the respective user. In particular, a user when driving his motor vehicle into his garage immediately visually control the desired and advantageous him predeterminable parking position on the basis of the visible directional rays visually.

Advantageously, the or each transmitting element is formed by a laser diode.

The laser diode generates sharply focused beams, with which the respective target position can be displayed exactly.

Particularly advantageously, the or each transmitting element on the carriage of the drive unit is arranged directly or driving with this and is controlled by an electronic unit in this carriage. The control is then preferably such that the door is moved from the closed position to the ventilation position when the humidity measured with the sensor exceeds a threshold value.

By coupling the or each transmitting element to the carriage no separate supply for these transmitting elements is provided, which significantly reduces the design effort.

FIG. 1 schematically shows a drive system 1 for a gate 2, which is formed in the present case as a garage door in the form of a sectional door.

The gate 2 is guided at both edges in each case a guide rail 3. Each guide rail 3 has a rail segment running in the vertical direction and a rail segment running in the horizontal direction on. The horizontal and vertical rail segments are connected by a curved rail segment.

FIG. 1 shows the gate 2 in its closed position, in which the door 2 is arranged between the vertical rail segments of the guide rail 3 and closes a door opening of the garage. In an open position, the gate 2 is arranged between the horizontal rail segments of the guide rail 3, which extend under the ceiling of the garage.

By means of the drive system 1, the door 2 can be moved between the closed position and the open position.

The drive system 1 has a movable on one of the guide rails 3 door drive 4 as part of a drive unit, which has an integrated in a carriage 5 electric drive 6, that is electric motor has. The door drive 4 is connected by means of a push arm 7 hingedly connected to the upper edge of the door 2.

Furthermore, the drive system 1 as part of the drive unit comprises a control unit 8, which is connected to the door drive 4 via power supply means, not shown. The control unit 8, which is mounted in the present case on the inside of a wall of the garage, generates control signals for moving the door drive 4. In or on the control unit 8 is a receiver 9, which is adapted to receive radio signals. The radio signals registered at the receiver 9 are evaluated in the control unit 8.

This receiver 9 are associated with one or more handheld transmitters. Each hand-held transmitter has a push-button operable radio transmitter element. The radio transmitter element emits radio signals which are received by the receiver 9 and converted by the control unit 8 into control commands for moving the door 2.

The door 2 can be moved by means of the drive system 1 not only in an open position and a closed position, but also in a ventilation position. In the ventilation position, the door 2 closes the door opening of the garage, unlike in the closed position, not completely off, but leaves a vent open through which an air exchange between the interior of the garage and the outside can be done. The ventilation slot can be achieved by tilting the top section of the sectional door and / or slightly raising the lower door edge of the garage floor.

The drive system 1 performs a sensor-controlled movement of the door 2 between the closed position and the ventilation position in order to prevent mold formation within the garage. The control takes place as a function of the sensor signals of a humidity sensor 10, which measures the humidity in the interior of the garage. The moisture sensor 10 is arranged on the carriage 5 in the present case. The control can be carried out by the control unit 8 or particularly advantageously by an integrated electronics unit in the carriage 5.

The control is performed such that the moisture detected by the humidity sensor 10 is compared with a threshold value. If the determined humidity is below the threshold value, the door 2 is moved into the closed position. However, if the determined humidity is above the threshold value, then the door 2 is moved into the ventilation position, so that moisture can escape from the interior of the garage via the ventilation slot. However, if the humidity in the outdoor area is greater than that in the interior of the garage, for example, in heavy rain, so would the humidity in the garage with open ventilation position. This is also detected with the moisture sensor 10, so that then the gate 2 is moved to the closed position via the electronics unit, in order then to move the gate 2 back into the ventilation position at a later time.

On the carriage 5, a transmitting element in the form of a laser diode 11 is further arranged, which is also controlled by the electronic unit. The laser diode 11 emits, as in FIG. 2 shown, sharply focused, visible beams 12. These beams 12 are used for display, that is visualization of the parking position of a retracted into the garage motor vehicle 13. Alternatively, the transmitting element can be arranged on the push arm 7.

The control of the laser diode 11 is carried out such that it is activated upon opening of the door 2 and then displays the parking position by a light spot on the hood of the motor vehicle 13 in the open position.

The drive system 1 further has a burglar alarm, whose components in the FIGS. 3 and 4 are shown. FIG. 3 schematically shows the electric motor of the drive unit. On the rotor is the first component of the burglar alarm, firmly connected to this, a stop plate 14 is provided which in FIG. 4 is shown in a single representation. The circular stop disc 14 has each side opening out two pairs of stop elements 15, which are arranged offset by 180 °. The stop elements 15 are each formed by bulges in a projection of the stop plate 14.

As a further component of the burglar alarm, the stop disk 14 is assigned a locking element 16 with a lifting magnet 17, which is controlled by the control unit 8. The solenoid 17 can be moved between an unlocked position and a locking position. FIG. 3 shows the solenoid 17 in its unlocked position in which the solenoid 17 is outside the range of the stop plate 14 so that the rotor of the electric motor can rotate freely. If the solenoid 17 is brought into the locking position, it projects into the region of the stop plate 14. At the latest after half a revolution of the rotor of the solenoid 17 is located on one of the stop elements 15, so that the electric motor is completely blocked, that is, the rotor can not continue to turn.

Advantageously, the solenoid 17 is then retracted into a locking position when the door 2 is in the ventilation position. Thus, the door 2 can not be raised in the ventilation position. The locking of the electric motor via the locking element 16 can be done in freely selectable positions of the door 2, for example, in the closed position of the gate. 2
