Definitions
- the invention relates to an arrangement for displaying an operating state of a device.
- the object of the invention is to provide a display which is simple to produce, can be implemented over a large area, consumes little power in the activated state and automatically switches to the inactive state in the event of a power failure. Presentation of the invention
- the invention consists of an arrangement for the optical display of two states, in which a small direct current collector motor is inserted in a roller, is non-positively connected to it and its axis is connected to the housing which comprises the roller , wherein the roller is rotated by energizing the small motor and another segment on the roller is thus visible through a viewing window.
- the small motor is fed from a current source of high internal resistance and rotated against a spring force.
- the spring force returns the roller to the idle state.
- a second embodiment only requires a current flow through the motor for the adjustment.
- permanent magnets are used, which serve as stops for the rotation of the roller and hold the roller in the respective position by means of an iron plate striking against it.
- the energy for resetting is stored in a capacitor and supplied to the motor when the control voltage is switched off.
- Fig. 1 shows a cross section through the display
- Fig. 4 shows a circuit for the control with dynamically low internal resistance.
- FIG. 1 shows a cross section through a display device according to the invention.
- 2 shows the corresponding longitudinal section.
- a half cylinder 11 which is rotatably mounted in the cylindrical cavity.
- two different fields 17 and 18 which can be brought under the window 14 by rotating the half cylinder 11.
- Two stops 15 and 16 limit the rotation of the half cylinder 11, so that one of the fields 17, 18 is visible from the outside through the window 14.
- a spring 19 rotates the half cylinder in the direction of the stop 15, so that the field 17 is visible through the window 14 in the idle state.
- the two fields 17, 18 differ in their color or in lettering such as "ready" or "out of order".
- the half cylinder 11 has a concentric cylindrical cavity inside, which is closed at both ends by semicircular segments which have bores 25 along the axis of the half cylinder.
- a small motor 12 with a cylindrical outer housing is attached to one end of the half cylinder 11.
- the inside diameter of the half cylinder is only slightly larger than the outside diameter of the motor 12, so that it is non-positively connected to the half cylinder 11, for example by an adhesive 21.
- the axis 13 of the motor 12 protrudes through the axial bore 25 of the half cylinder 11 into a bore of the housing 10.
- a fixation 23 fastens the axis 13 of the motor 12 to the housing 10.
- the axis 13 of the motor 12 is non-positively connected to the housing , but rotatable in the bore 25 of the half cylinder 11.
- a torque between the housing 10 and half cylinder 11 causes.
- the half-cylinder 11 is rotated against the moment of the spring 19 up to the stop 16, so that the second field 18 is visible in the window 14.
- the torque is also eliminated, so that the half-cylinder rotates back into the rest position due to the torque of the spring 19.
- the motor is connected by flexible connecting strands 22 since its rotary movement is less than 360 °.
- a series resistor 36 with a capacitor 35 connected in parallel is used, so that there is a statically high, but a dynamically low internal resistance of the current source.
- a motor with a much larger nominal voltage than the applied operating voltage can be used, so that the current flowing at a standstill is less than the nominal current of the motor when moving.
- a motor with 24V nominal voltage and 5V operating voltage can be used.
- a second bearing point 24 is provided on the end of the half cylinder opposite the motor 12.
- a second motor of the same type as on the opposite side can also be used as a bearing and optionally supplied with current.
- the two stops 15 and 16 are designed as permanent magnets.
- the half-cylinder has soft iron plates at the points that abut the stops 15 and 16, which are not shown in the figures. These are attracted to the respective permanent magnet stop when they are close to it. This means that the idle and display positions are retained even when the motor is not powered.
- a spring 19 can continue be in place to support the deferral; however, it must be dimensioned such that the force exerted by it is certainly less than the holding force of the soft iron plate at the stop 16 minus the forces caused by vibrations.
- a series connection of a capacitor with the small motor is used to control this arrangement.
- the on / off switch edge is differentiated by the capacitor and leads to a current pulse through the motor, which thereby rotates the half-cylinder 11 in the other direction against the stop 15 or 16, the respective position being determined by the permanent magnetic Stops 15 and 16 is fixed.
- the small motor 12 is connected in series with a capacitor 35 at the common pole of a changeover switch 33 and at a reference potential which is connected to the rest pole of the changeover switch 33.
- the working pole of the changeover switch 33 is connected via a diode 34 to the input voltage, which is simultaneously connected to a relay 32 which operates the changeover contact 33. If this arrangement is connected to a suitable voltage, the relay picks up after the tightening voltage has been reached. The changeover contact thus switches the motor 12 to this voltage via the capacitor 35.
- the charging current of the capacitor 35 flows through the motor and causes the half-cylinder 11 to rotate as far as the stop 16. After the capacitor has been charged, no more current flows through the motor, but only the current through the relay. Its current consumption can be further reduced in a known manner by a capacitively bridged series resistor.
- the capacitor 35 prevents the capacitor 35 from being discharged and thus improves the switch-off behavior. It prevents the capacitor from discharging through the relay and only the energy remaining in the capacitor when the relay drops out is available for the reset process. It can be omitted if the relay is dimensioned and the capacitor is chosen large enough that the energy stored in it at the drop voltage of the relay is sufficient to separate the roller 11 from the stop 16 and to turn it to stop 15.
- a resistor 37 which is shown in broken lines in FIG. 3, can be connected in parallel with the capacitor. A quiescent current is thus set, which produces a moment opposite to the moment of the spring.
- the relay must be selected so that, as described above, the diode 34 can be omitted, since the capacitor discharges through the resistance when the operating voltage drops.
