Abstract: The invention relates to a drive system for a gate, the gate panel thereof being guided in a guide rail on each side. A carriage is guided in one of the guide rails, and a pusher arm is joined with a hinge to the carriage and the upper edge of the gate panel. A motor is supported on the pusher arm.

Abstract: A drive unit for a door includes a guiding device comprising guide rail and a guide element extending in a movement direction of the door. A drive device arranged inside a carriage moves back and forth along the guide rail and is engaged in the guide element. The drive unit is supplied with power via the guide rail and the guide element. Electrical plug connectors are provided on an external power source for the electrical connection of the guide element and the guide rail.

Abstract: A method to access a control system for a gate or a door, wherein the control system includes a fingerprint sensor, a scanner for capturing a fingerprint as a user identifier for a user, a sensor element for activating the scanner and a computer unit, which stores a number of user identifiers. A fingerprint captured using the scanner is compared, as a currently input user identifier, with the user identifiers which are stored in the computer unit. If there is a match between the currently input user identifier and a stored user identifier, the fingerprint sensor outputs a control signal to a control unit, as a result of which the latter operates the gate or the door. Signals generated in the scanner are used to selectively call individual memory locations in the computer unit in order to erase or store individual user identifiers therein.

Abstract: A weight compensation system is provided for a motor driven door having a door leaf that is driven by a mechanism inside guide rails on a side of the door leaf to move the door between an opened position and a closed position. The weight compensation system includes a weight-compensation device comprising a cable unit and a spring unit arranged at least on one side of the door leaf, wherein the cable unit comprises a single cable. A cable-tension compensation device at which the single cable is deflected creates two cable strands that are secured against breakage within the cable-tension compensation device. The cable-tension compensation device is positioned locally fixed or secured to the door leaf so that two cable strands move at a distance to each other, and the exposed ends of the cable are guided together and attached to the door leaf or are positioned locally fixed, respectively.

Abstract: The invention relates to a drive system for a door, the door leaf of which is guided at the sides in respective guide tracks. A carriage that is guided along a guide track is connected to the door leaf. The carriage contains an intergrated drive with an autonomous power supply. The drive can be charged at a stationary charging station a wireless power supply unit. A safety device is connected via a wireless signal transmission path to a control unit that is allocated to the drive.

Abstract: The invention relates to a drive system for a gate, the gate panel thereof being guided in a guide rail on each side. A carriage is guided in one of the guide rails, and a pusher arm is joined with a hinge to the carriage and the upper edge of the gate panel. A motor is supported on the pusher arm.

Abstract: The invention relates to a drive device, particularly for doors, garage doors, etc., comprising a guide device, particularly a rail or guide rail, extending in movement direction of the door. The invention is characterised in that the feed means comprises a first insert body which can be plugged at the ends of the guide rail into this and is provided with a connecting cable and which is held at the guide rail end and constructed in such a manner that it fulfils its function not only at one end of the guide rail, but also at the other end of the guide rail.

Abstract: The invention relates to a method and a device for controlling an electric door drive. During a learning process determination of the course over time of the torques of the door drive for each of at least one opening process and closing process is carried out. Maximum permissible torques are derived from the ascertained torques for predetermined zones within an opening process and closing process. During operation of the door drive a comparison of the current torque with the maximum torques and a comparison of the current speeds of the door drive with predetermined target speeds are carried out. The current speed of the door drive is increased if the associated target speed is fallen below. In addition, switching-off the door drive takes place if the current torque exceeds the associated maximum torque.

Abstract: The invention relates to a programming apparatus for programming transmitter/receiver systems for contactless actuation of doors and gates. For actuation of a door or a gate by a transmitter of a transmitter/receiver system a transmitter code is read into an associated receiver and compared there with receiver codes. The programming apparatus according to the invention comprises a computer unit for management of the transmitter codes and the receiver codes of the transmitter/receiver systems. In addition, the programming apparatus according to the invention includes an input unit for definition of the transmitter codes and the receiver codes of the transmitter/receiver systems. Moreover, the programming apparatus according to the invention comprises an interface unit for connection of transmitters and receivers, by way of which receiver codes can be issued at connected receivers and transmitter codes at connected transmitters.

Abstract: A closing system for a non-contacting operation of a door or a gate comprises a transmitter/receiver system including a plurality of transmitters and a receiver. Each transmitter respectively includes a computer unit and an input device. Each input device is operative to program a transmitting code into the respective computer unit. The receiver includes a storage unit with at least one storage location for storing the transmitting codes transmitted by the transmitters during a teach-in process.

Abstract: The invention relates to a closing system (1), comprising a transmitter/receiver unit for the non-contacting operation of a door (2) or a gate, as well as to a method for its operation. In order to operate a door (2) or a gate, a transmitting code is transmitted by an authorized transmitter (3) to the receiver (4). The authorized receivers (3) are defined in that their transmitting codes can be read into the receiver (4) by means of a teach-in mode. The receiver (4) can be switched to the teach-in mode upon receiving an identification code from a freely selectable transmitter (3) if the number of transmitting codes for authorized transmitters (3), stored in the receiver (4), is below the limit value (NG) predetermined for the receiver (4). The receiver (4) can be switched to the teach-in mode only upon receiving an identification code from an authorized transmitter (3) if the number of transmitting codes of authorized transmitters (3) that are stored in the receiver (4) corresponds to the limit value (NG).
