Definitions

  • the invention relates to a device for closing a predetermined opening, in particular a wall opening, with a along a predetermined path between a closed position and an open position movable, for example in Form of a door leaf formed closing element and one for Detection of obstacles in the area of the specified path and for outputting corresponding detection signals operable detection device.

  • a control device usually to effect electrical drive.
  • the particular during a closing movement from the open position to the closed position occurring danger to people and objects in the Movement space of the gate, i.e. in the area of the specified path is usually achieved through the use of detection devices diminished, with which the obstacles are grasped and corresponding Detection signals emitted and used to control the drive the control device can be created.
  • Detection devices used in the form of light barriers, which are fixed with respect to the wall defining the opening and / or move with the door leaf.
  • So provided with a drive for the door leaf.
  • a light barrier in an in Form of a hollow profile formed rubber locking strip on the during the closing movement leading closing edge as proven particularly useful. If the one with the light barrier provided rubber closing strip encounters an obstacle, the Light beam of the transmitter interrupted and a corresponding detection signal submitted. In response to this detection signal the closing movement can be stopped with the control device and possibly an opening movement over a predetermined one Route to clear the obstacle.
  • Such detection devices are not in Connection with industrial gates, especially high-speed gates can be used, which are moved at a high speed because the door leaves are braked without delay this goal is not possible when hitting an obstacle. If the obstacle is only touching the front edge of the gate therefore, injuries and damage can be detected of people and objects themselves by using the Detection devices described above are not be prevented. For this reason you are using a high speed movable closing elements passed, the light barrier at a predetermined distance to be arranged in front of the front closing edge of the closing element, the more so when an obstacle is detected to slow down the To provide sufficient braking distance for the closing element.
  • this solution is deficient in that in one transverse to the predetermined direction between the Photoelectric sensor and the front closing edge of the closing element introduced obstacles and therefore injuries and Damage cannot be reliably prevented.
  • Pressure sensors such as foot mats in the area of use predetermined path of the closing element with which Obstacles can be detected.

  • ultrasonic sensors are structural simple, for example in the form of simple piezo crystals producible and usually take up so little space, that their installation in a locking device, such as a gate without significant additional design effort can be made.
  • the invention In view of the comparatively slow propagation speed of sound waves in air can with the invention Device not only the presence of an obstacle, but also its distance from the ultrasonic sensor can be determined contactless.
  • the radiation element is expedient for this purpose designed to emit individual ultrasonic pulses, during the ultrasonic sensor to determine the Period between the emission of the ultrasonic pulses and the detection of the ultrasonic waves reflected by the obstacles operable timer is assigned. With this It is possible to arrange only if there is an obstacle in the area of the predetermined path of the closing element display signal to generate if by multiplication of the period recorded with the timer with the known propagation speed of the sound waves Distance between the obstacle and the ultrasonic sensor falls below a predetermined value.
  • the invention is Development of the known devices with special Can be used to advantage if the closing element is preferably used with a electric drive is movable, one for control the movement of the closing element operable control device assigned.
  • the risk of People and / or objects due to the movement of the closing element be excluded particularly reliably if the Control device in response to that by detecting the of the obstacles with the ultrasonic sensor triggered detection signals for changing the movement of the closing element, preferably by braking and / or reversal of the direction of movement is operable.
  • the Control device in response to that by detecting the of the obstacles with the ultrasonic sensor triggered detection signals for changing the movement of the closing element, preferably by braking and / or reversal of the direction of movement is operable.
  • the closing element in response to the detection signals corresponding to a predetermined one Braking the speed ramp and possibly along one move back the specified distance in the opposite direction.
  • the closing element itself the radiation area of the radiating element and / or in the Detection area of the ultrasonic sensor arrives. In this case must be prevented from being reflected by the closing element and the ultrasonic sensor detects ultrasonic waves for triggering of a detection signal. That can be achieved if the emission of ultrasonic waves is prevented as soon as the closing element reaches the corresponding radiation area and / or the ultrasonic sensor is only activated when the locking element is not in its detection range located.
  • the Control device for applying the radiation of ultrasonic waves initiating and / or activating the ultrasonic sensor Control signals can be operated.

  • the generation of by the movement of the closing element even triggered detection signals can be effective can be suppressed if at least one ultrasonic sensor is related the closing element is fixed and together with this is movable.
  • Ultrasound sensor can ensure one for one reliable detection of obstacles necessary precise positioning can be reliably prevented if the regarding the locking element fixed ultrasound sensor against the biasing force a pretensioner in one of the directions of movement opposite of the closing element during the closing movement Direction is movable.
  • a pretensioner in one of the directions of movement opposite of the closing element during the closing movement Direction is movable.
