Such a drive system is from the DE 102 27 110 A1 known. The drive system is generally designed as a door drive system, in particular as a garage door drive system. For moving a door leaf between a closed position and an open position, a carriage which can be moved on a guide rail is provided, in which an electric drive is integrated. The carriage is mechanically connected to the door leaf via a push rod. By moving the carriage on the guide rail between a first and second end position so that the door leaf is moved between a closed position and an open position and closed or opened the access to the garage.

To supply power to the electric drive power supply means are provided. These power supply means are formed by the guide rail itself and a tensioned in the guide rail traction means. For clamping the chain two insert body are provided, wherein the insert body are inserted at opposite ends of the guide rail. One of the insert body forms another power supply means. This insert body carries a cable that can be connected to a power supply.

In this drive system, the electric drive is only supplied with power when it is moved along the chain.

The invention has for its object to extend the functionality of the drive system mentioned above with the least possible design effort.

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

The drive system for a gate according to the invention comprises a traveling carriage which can be moved on a guide rail and in which an electric drive is integrated. The carriage is mechanically connected to a door leaf, so that by moving the carriage between a first and second end position, the door leaf is moved between a closed position and an open position. The electric drive is powered by current supply means with continuous current. At least one functional element is arranged on the door leaf, the voltage supply of which is effected via control means integrated in the carriage.

The basic idea of the invention thus consists in attaching electrical functional elements to the door leaf, the supply voltage of which being made available via the carriage of the drive system. Thus need for power or voltage supply no expensive accumulators or the like may be provided on the door leaf. Also need not be provided by the functional elements consuming, complicated to be laid cable to a stationary power supply in the door frame or in adjacent wall elements.

Rather, the current or voltage supply can take place in a structurally simple manner in that one or more cables are guided by the carriage onto the door leaf. This is therefore particularly easy to carry out, since the carriage is mechanically, preferably via a push rod, connected to the door leaf. This connection can be used for the cable connection. Since the distance between carriage and door leaf is constant, that is always the same, no complex spiral cable is required.

An essential aspect of the invention is that the electric drive and thus the carriage are supplied with continuous current, so that correspondingly the functional elements are supplied with power permanently or on demand. In this case, as a further essential elements in the carriage control means, preferably a microprocessor integrated. The control means convert the high mains voltage values or continuous currents into respectively suitable lower supply voltages or weak currents for the functional elements on the door leaf.

The control means may be part of an integrated in the carriage controller, which serves to control all the functions of the drive system. Alternatively, the controller may be stationarily located outside the carriage and connected to the carriage via spiral cables.

In the drive system according to the invention, the power supply means of the guide rail and a tensioned in the guide rail traction means, which is in engagement with a driven by the electric drive wheel, formed. In or at the longitudinal ends of the guide rail insert body are arranged, which are designed for tensioning the traction means, wherein at least one insert body is designed as a power supply means.

By provided on the door leaf functional elements, the functionality of the drive system according to the invention is considerably expanded. Furthermore, it is advantageous that the functional elements can already be integrated ex works in the door leaf, resulting in a preassembled unit.

According to an advantageous embodiment, a functional element is designed as a fingerprint sensor, wherein the door leaf is moved from its closed position into its open position by actuating the fingerprint sensor.

If a fingerprint of a user is recognized as being valid with the fingerprint sensor, a control command is generated in the control system with which the gate is opened, that is, the door leaf is moved from the closed position to the open position. Suitably, the fingerprint sensor is heated with the supply voltage, so that it is always functional, regardless of external weather conditions.

Since the fingerprint sensor is no longer accessible in the open position of the door leaf, further operating elements are provided for opening and closing the door. These can be formed by a fixed probe, a stationary fingerprint sensor or by mobile handheld transmitters.

In accordance with a further advantageous embodiment, a functional element is formed by a wicket door switch, with the wicket door switch monitoring a wicket door integrated in the door leaf.

The signal states of the wicket door switch are evaluated in the controller.

• Kurzschluss
• Kabelbruch
• Tür zu

These signal states are the following:

• short circuit
• cable break
• close the door

These signal states are defined by defined, different voltages that can be checked by a monitoring circuit integrated in the control.

Advantageously, in the control, a functional check of the wicket door switch, this function test is activated by opening the wicket door every day.

Typically, the functional test is performed at predetermined time intervals, which are about six weeks. Compliance with the time intervals is checked in the controller.

If after a lapse of a time interval the wicket door is not opened and the functional test is not started, the control activates an optical or acoustic signal generator which indicates to a user the due function test. This signal generator can advantageously be designed as a functional element attached to the door leaf. Alternatively, the signal transmitter may be located on the carriage or in the garage.

As a further security function, the optical signal transmitter and / or the warning signal forms another functional element.

This warns a user that the door can not be opened due to the open wicket door. This warning indicator can also be a functional element arranged on the door leaf. The warning leather can be designed as an optical or acoustic warning.

As a further security function, a light source is provided as a further functional element, by means of which, when the wicket door is open, its threshold is illuminated.

Thus, a user is visually warned of the tripping trap forming threshold.

As additional functionality, a light source is activated when the wicket door is open, which illuminates the space that can be locked with the door leaf.

Finally, a further functional element in the form of a light source can be provided as a further safety function, by means of which the space below the closing edge of the door leaf is illuminated when the door leaf is located outside the closed position.

A user is thus shown the danger area below the closing edge of the door leaf.

According to an advantageous development, lighting elements are provided on the door leaf as further functional elements.

The lighting elements can generally fulfill additional functions. For example, this can visualize the house number of a building. Likewise, lighting elements can form design elements such as trim strips.

FIG. 1 schematically shows a garage 1 with a gate on the front side. The gate comprises a door frame and a door leaf 2 mounted therein in its closed position. A wicket door 3 is integrated in the door leaf 2. The gate is designed in the present case as a tilt gate. Alternatively, the door may be formed by a sectional door or the like, which is guided laterally in rails.

For actuating the door, that is to move the door leaf 2 in a closed position, in which the door leaf 2 as in FIG. 1 shown closes the door opening, and in an open position in which the door leaf 2 is retracted under the ceiling of the garage 1 and thus releases the door opening, which is in FIG. 2 shown drive system 4 is provided.

The drive system 4 comprises a carriage 5, which is movable along a guide rail 6. The carriage 5 is connected via a push rod 7 hingedly connected to the upper edge of the door leaf 2. By moving the carriage 5 between a first and second end position on the guide rail 6, the door leaf 2 is moved between the closed position and the open position. The guide rail 6 is fastened with fastening means 8 close to the ceiling of the garage 1. At the longitudinal ends of the guide rail 6, an insert body 9a, 9b is inserted in each case. A first insert body 9a is fastened with attachment means 10 on the lintel of the garage 1, which limits the door opening at the top. At the second insert body 9b, a cable 11 opens, which is plugged into a power supply 12 in the wall of the garage 1.

The power supply 12 may also be arranged at one end of the guide rail 6.

In the guide rail 6 runs as a pulling means a chain 13, which is stretched with integrated in the insert bodies 9a, 9b Zugmittelspannvorrichtungen.

In the carriage 5 is an electric drive 14 which drives a drive wheel 15, in particular gear, which is in engagement with the chain 13. Depending on the direction in which the driven by the electric drive 14 drive wheel 15 rotates, the carriage 5 is moved in a direction of movement along the guide rail 6 ( FIG. 2a ).

Furthermore, in the carriage 5, a controller 16 is integrated, which controls the entire functions of the drive system 4. The controller 16 also includes a microprocessor 17 as the control means.

The second insert body 9b and the guide rail 6 and the chain 13 form power supply means, by means of which the electric drive 14 is supplied with power. It is essential that the electric drive 14 and all other components of the carriage 5 are supplied with continuous current. The current is thus supplied via the cable 11 and the power supply means on the one hand to the electric drive 14, so that it can drive the drive wheel 15. On the other hand, the power is supplied to the controller 16 and the microprocessor 17. The microprocessor 17 converts the mains voltage into a lower supply voltage, with which a permanent voltage supply of functional elements on the door leaf 2 takes place.

For this purpose, at least one cable 18 is guided over the push rod 7 on the door leaf 2. Via the cable 18, in addition to the power supply, a signal transmission can take place. Alternatively, the signal transmission takes place via radio systems.

A first such functional element is the in FIG. 3 illustrated fingerprint sensor 19 which is arranged on the outside of the door leaf 2.

The fingerprint sensor 19 has, in a known manner, a scanner 20 by means of which fingerprints can be read by persons. Furthermore, the fingerprint sensor 19 has a sensor element 21, by means of which the scanner 20 can be activated for reading a fingerprint. The sensor element 21 is formed in the present case by a capacitive sensor. Alternatively, the sensor element 21 may also be designed as an inductive sensor, mechanical sensor and the like. The fingerprint sensor 19 is connected to the controller 16.

With the fingerprint sensor 19, an access control is provided in such a way that only selected persons can open the door. Of these selected persons, the fingerprints are stored in the fingerprint sensor 19. If a person presses the fingerprint sensor 19, then their fingerprint is read by the scanner 20. The read fingerprint is then compared with the fingerprints stored in the fingerprint sensor 19. Only when the currently read fingerprint matches one of the stored fingerprints will the gate be opened. Advantageously, the fingerprint sensor 19 is heated with the supply voltage provided.

Since, after opening the door, the door leaf 2 is located in the area of the ceiling of the garage 1, the fingerprint sensor 19 arranged on the door leaf 2 is no longer accessible to a user, so that the door can no longer be closed with this fingerprint sensor 19. Therefore, further controls, such as hand-held transmitters or a stationary fingerprint sensor or buttons are preferably provided with which the door can be opened and closed.

Another functional element is how FIG. 2 shows a wicket door switch 22 assigned. The wicket door switch 22 detects whether the wicket door 3 is closed or open.

• Tür zu
• Kabelbruch
• Kurzschluss

The signals generated in the wicket door switch 22 are evaluated in the controller 16. The wicket door switch 22 generates the signal states

• close the door
• cable break
• short circuit

These signal states can be distinguished in the controller 16 in that these signal states correspond to different voltage values which are selectively detected in the controller 16.

Furthermore, in certain, preferably adjustable by the user time intervals, which are typically about six weeks, carried out a functional test of the wicket door switch 22 by the controller 16. The functional test is initiated by opening the wicket door 3.

To ensure compliance with the examination intervals, a user is signaled if the wicket door 3 has not been opened after the expiration of a time interval. For this purpose, a signal generator 23 is provided as a further functional element on the door leaf 2, which generates an optical or acoustic signal which indicates to the user that he must open the wicket door 3 in order to initiate the functional test of the wicket door switch 22.

Advantageously, this signal output takes place when the door leaf 2 is actuated, in particular only for a limited period of time. This signal is emitted repeatedly until the function test of the wicket door switch 22 is started by opening the wicket door 3.

If the wicket door 3 is open, the door can not be opened. In order that a user does not erroneously trigger a door opening in this case, the user is presented with the open wicket door 3 with an optical or acoustic warning signal which is generated in a warning detector 24. In the present case, the alarm 24 is arranged on the door leaf 2 and thus forms another functional element.

The interior of the garage 1 is generally lit with a light source. This light source is controlled via the drive system 4 such that it is turned on not only when the door is opened, but also when the wicket door 3 is opened.

As a further functional element, a planar light source 25 is arranged in the area of the upper side of the frame of the wicket door 3 ( FIG. 4 ). This light source 25 is controlled by the controller 16 such that it is activated when the wicket door 3 is open. With the surface emitted from the light source 25 visible light rays 26 then the threshold 27 is illuminated at the bottom of the frame of the wicket door 3. Thus, a user is alerted to the threshold 27 forming a trip-trap.

Another functional element is how FIG. 5 shows, on the lower edge of the door leaf 2, which forms a main closing edge, a further planar light source 28 is provided. This is controlled by the controller 16 such that it is activated when the door leaf 2 moves toward the closed position. With the surface, visible light beams 29 emitted by the light source 28, the danger area below the main closing edge is then illuminated, whereby a further safety function is provided.

Finally, 2 other lighting elements may be provided as further functional elements on the door leaf, which may be formed, for example, as LED bands or LCD displays. These can be pure design elements or even fulfill additional functions, such as the display of the house number of a building.
