Definitions

  • the invention relates to a trigger with a vertical movable sliding window for opening and closing the work area in the trigger that hangs on at least one counterweight is and via a rope or connected to the sliding window belt-like drive device is driven, and with at least a position measuring and arranged on the sliding window Monitoring device.
  • the sliding window is usually that runs vertically from top to bottom, via double guides Ropes connected with one or more counterweights, to keep it in balance.
  • the reason for the double rope guide is that if a rope breaks, the second rope keeps the sliding window in balance.
  • Control devices can be provided that the sliding window close automatically if the trigger is not being worked on. So that the sliding window does not during the automatic shutdown is damaged, is at the bottom of the sliding window Sensor provided, for example in the form of a light barrier, which monitors the space below the lower edge of the sliding window.
  • a sensor consists of a transmit and a Receiver part with separate supply and signal lines are attached to the trigger.
  • a sensor is also provided that covers the area monitored under the bottom edge of the sliding window, more must be done Cable for the transmitter part and the receiver part, i.e. Supply cable and signal cables can be provided.
  • the object underlying the invention is therefore in making a deduction of the type mentioned at the beginning, that it has a smaller number of ropes, straps or lines gets along.
  • the rope or belt-like drive device thus as an electrical signal and Supply line.
  • the electrical lines that are used in a normal deduction lead to the measuring device are no need for this training thus the electrical lines that are used in a normal deduction lead to the measuring device.
  • the sliding window is preferably on the rope or belt-like drive device suspended from the counterweight.
  • This training has the further advantage that the two Ropes are unnecessary, which with the usual deductions, the sliding window Hang up counterweights.
  • a additional rope or an additional strap for hanging the Sliding window on a counterweight parallel to the rope or belt-like drive device may be provided.
  • the detector is preferably in the sliding window frame built-in.
  • the training according to the invention thus have the advantage a significantly smaller number of connections and connections to the movable sliding window, so the danger it is less that cables, ropes or straps are jammed or damaged or be sheared off. Fitting the trigger, in particular the electrical and mechanical connections to the sliding window, is due to the lower number of such connections much easier.
  • Fig. 1 and 2 of the drawing has a fume cupboard on an interior or work space, which is usually at the front through a vertically movable sliding window 1 can be opened and closed.
  • the sliding window 1 is on a toothed belt 2 on one Counterweight 9 suspended, the U-shaped via pulleys 3 and 4 is led.
  • a drive motor 5 acts on the toothed belt 2, its driving force via the toothed belt on the sliding window 1 is transmitted to move this up and down.
  • the drive motor 5 is provided with a clutch so that it is only actuated Coupling engages timing belt 2. When not activated Coupling, the toothed belt 2 is freely movable. Because of the timing belt 2 can drive motor 5 at any point be clicked.
  • the sliding window 1 can on both sides be hung a timing belt in this way.
  • the toothed belt 2 is with especially wedge-like teeth 12 and provided by a soul 13 made of an electrically conductive material, for example Reinforced steel core.
  • a V-belts or a rope with an electrically conductive core are provided be.
  • the sliding window is 1 a terminal 11 is provided which is electrically connected to the soul 13 of the toothed belt 2 is connected. Likewise is on Counterweight 9, a terminal 10 is provided to the one Trailing cable 8 is connected to a current terminal 7 leads.
  • the terminal 11 on the sliding window 1 has electrical Taps on the output signals and the supply voltages for the sensor, which is not shown in FIG. 2 is shown and on the underside of the sliding window 1 for Monitoring of the room below the lower edge of the sliding window 1 is provided.
  • the supply voltage and the output signals are corresponding to the soul 13 of the toothed belt 2 Evaluation and control devices supplied, which may provide a drive interruption of the drive motor 5 if there is an obstacle in the space below the window edge or the sliding window has reached its lowest position, so that it is not damaged when shutting down.
  • a rotary encoder 6 provided the information about the vertical position of the sliding window 1 on the toothed belt 2.
  • This Encoder 6 can, for example, be designed so that it is a has 2 driven roller during the passage of the toothed belt, about their number of rotations to the vertical position of the Sliding window 1 can be closed.
  • the encoder 6 is connected via stationary electrical cables. The electrical Signals from the detectors and sensors are also sent over the trailing cable 8 to signal terminals on the top of the Deduction led.
  • detectors in particular switches or Pushbuttons built in, which provide information about the horizontal Deliver position of the cross slide 14. This information will likewise via the electrically conductive core of the toothed belt 2 passed.
