Definitions

  • the invention relates to a safety device according to the preamble of claim 1.
  • Power operated devices such as gates, doors or windows work e.g. together with an electromechanical drive, which in garage doors consists of a guide rail mounted on the garage ceiling, in which a carriage coupled to the gate by means of an articulated rod is guided in a longitudinally movable manner by means of a drive motor and by means of a form-fitting element.
  • the form-fitting element runs in a straight line and parallel to the guide rail, with it being elastically fixed at both ends by means of springs.
  • the drive is also equipped with a blocking and obstacle shutdown, e.g. is described in DE 35 46 282 C2.
  • Such a garage door drive has a high sensitivity, works reliably, but has the disadvantage that the drive cannot distinguish whether the door is supported on the floor or is in contact with an obstacle.
  • DE 3514 223 C2 discloses a method for switching off or reversing an electric motor for driving a movable opening closure, the increase in the current drawn by the motor being monitored and the motor being switched off when a preselected setpoint value is exceeded or being switched in the opposite direction.
  • This method can be used if the opening closure is a relatively small and light weight device such as window panes, sunroof or the like.
  • This method is not absolutely applicable to larger devices, for example garage doors, which come into contact with obstacles when they are closed, in particular if these obstacles are easily crushable bodies located in the area of the pinching or closing edges.
  • the invention has for its object to provide a security device that can distinguish on the one hand whether the opening closure is operationally closed or completed, or on the other hand can determine whether the opening closure is in contact with an obstacle .
  • the safety device should be such that, if the opening closure is in pressure connection with a hinaernis, it releases it.
  • Another object of the invention is to design the safety device so that the user is always informed whether the safety device and / or the drive device is functioning properly.
  • the gate There is an obstacle in the path of movement of the gate, for example a person, then the person acts as a partially compliant obstacle, so that the predetermined maximum operating load of the drive device is only exceeded after a longer period of time after the signal S 1 has been emitted. This has the consequence that the safety device switches the drive device so that the opening closure moves in the opposite direction.
  • a particularly expedient embodiment provides that the sensor is arranged in the area of the main closing edge of the opening closure. It is expedient if the sensor has the shape of an elastically deformable body which extends along the main closing edge. Within the scope of this inventive concept, it is particularly expedient if the sensor is a body made of rubber or plastic filled with gas or liquid, which is connected via a line to a converter of mechanical impulses into electrical impulses.
  • an expedient embodiment of the invention provides that the sensor is designed as a damping body, the squeeze section of which, measured in the direction of movement of the door, is preferably more than 1 cm.
  • a garage door 14 is shown in the form of a sectional door.
  • the garage door 14 consists of a plurality of slats 22, 24, 26 and 28 which are guided in vertically oriented rails 30 and 32 which run parallel to one another and which also adjoin rails 34 and 36 which also run horizontally but are arranged horizontally.
  • the rails 34 and 36 are fastened to the ceiling of the garage by means of fastening means 38.
  • the main closing edge 27 of the gate 14, which can be moved back and forth in the direction of the double arrow 20, carries a sensor 18 which is connected to the safety device 10 via a line 8.
  • the safety device 10 is in turn connected via a line 6 to a drive device 12 of the gate.
  • the safety device 10 serves to control the sequence of movements of the gate 14, that with the drive device 12 with adjustable operating load and means by which the drive device 12 If their specified operating load is exceeded within a certain period of time, cooperates.
  • the safety device 10, which can be fastened, for example, to a side wall of the garage, can be operatively connected to the sensor 18 and to the drive device 12.
  • the sensor 18 is designed such that it can be brought into operative connection with obstacles crossing the path of movement of the gate 14, in this case emits a signal to the safety device 10 and thus has the effect that the direction of movement of the gate 14 is changed if its movement occurs within a certain period of time after the signal is not interrupted.
  • the operating position of the gate 14 is shown in the drawing.
  • the slats 22 to 28 are carried by the guide rails 34 and 36. If the safety device is now switched on, the slats 22 to 28 first move in the horizontal direction and then in the vertical direction until they have assumed the position shown in the drawing. The speed of movement of the slats depends on their position. If there is an obstacle between the bottom 4 and the lowest slat 28, then the sensor 18, which is arranged in the region of the main closing edge 27 of the gate 14, is brought into operative connection with the obstacle. As a result, the pressure inside the sensor, which is in the form of an elastically deformable body, which extends along the main closing edge 27 and is filled with gas or liquid, changes. The pressure wave is sent to a converter of mechanical impulses into electrical impulses.
  • the signal reaches the safety device 10 via the line 8, which has the consequence that a time measuring unit is switched on, which measures the time within which the set operating load the drive device 12 is exceeded.
  • a time measuring unit is switched on, which measures the time within which the set operating load the drive device 12 is exceeded.
  • the operating load is only exceeded later than in the case of non-deformable obstacles, so that the drive device is switched over and the slats of the door move upwards in the vertical direction.
  • the sensitivity of the sensor can preferably be increased by making it more voluminous.
  • the sensor is simultaneously designed as a damping body, the squeeze section of which, measured in the direction of movement of the slats, can be several centimeters.
  • the advantages achieved by the invention are, in particular, that it can be achieved with the simplest possible means that the movement sequence of the gate is not only interrupted, but also changed, so that a situation in which the obstacle is jammed cannot occur.
  • the safety device (control device) is also designed such that it is connected to a warning device which signals when the sensor is out of operation.
  • the control device first receives the signal from the drive device, which signals that the operating load on the drive device has been exceeded and that the sensor is out of operation.
  • the order of the incoming signals namely that of the sensor and that of the drive device, is also information about whether the control unit is working properly. If this is not the case, the gate can e.g. operated via a dead man's switch.
