Definitions

  • the invention relates to a tubular motor for winding and unwinding roller shutters, roller doors, awnings and the like. with a drive motor arranged in the winding tube, a switching element controlled by this and with independently adjustable limit switches for switching off the winding motor in presettable adjustable end positions of the armor, awning cloth or the like.
  • Such tubular motors are known. They have the particular advantage that they take up practically no additional space due to almost complete integration into the winding tube and are therefore preferably used to drive tanks for roller shutters, roller shutters or for winding the awning fabric in awnings.
  • the shaft of the winding motor has an external thread on which a traveling nut runs, which meets limit switches in the two end positions.
  • an adjusting screw with a probe is provided on the traveling nut Limit switch actuated.
  • this must be loosened from the winding motor shaft, axially displaced and fixed again.
  • the correction of a setting is also associated with a complete repetition of the entire towing process, because after loosening the determinations of the switch carriers, these are pulled back into the starting position by the tension spring. Access to the actuating lever attached to the eccentric shaft is also difficult, particularly when the roller shutter curtain is wound up.
  • DE-OS 31 31 316 eliminates the significant disadvantages, in particular of the limit switches which have hitherto been unsatisfactorily adjustable, in that each switch carrier is arranged to be displaceable as an actuating spindle which can be driven separately.
  • the threaded spindles can be mutually non-positively coupled with an adjusting knurled wheel arranged on the end of the tubular motor. In the two possible operative positions of the knurled wheel, this is either one Limit switch associated with a spindle or the other limit switch assigned with the other spindle rotatable, the corresponding limit switch moving along the spindle. With this device, a highly precise setting of the switching points is possible.
  • the invention is essentially based on the object to be able to achieve a precise setting of the limit switches quickly without having to accept the known access difficulties to the setting means.
  • the solution to this problem consists primarily and essentially in that the two limit switches are adjustable with at least one electric motor drive, the switches actuating this drive and possibly the voltage source for this drive being releasably connected to a plug-in coupling connected to the drive via a control cable can be connected.
  • the use of an electric motor drive for the adjustment of the end provides a considerable operating advantage switch is reached, which means that a push of a button instead of previously complex turning or screwing movements is sufficient for adjustment.
  • the switches for actuating the drive can be releasably coupled to a control cable by means of a plug-in coupling. This makes it possible to completely release the actuation for adjusting the limit switches from the area of the tubular motor, so that access to its vicinity is no longer necessary at all. It is therefore not necessary to remove the tubular motor to reach the limit switch, nor to reach into a narrow space and do manual work there.
  • the switches can be connected anywhere on the control cable, so this brings the greatest advantages.
  • the control cable-side coupling part of the plug-in coupling can in particular be fastened to the building.
  • the switch for the winding motor so in particular be integrated into the cover of a flush-mounted switch for the winding motor.
  • the fitter who has to set the end switching points of a tank for roller shutters or roller shutters or awnings can do this in the shortest possible time in the most convenient way. If you think that e.g. on a larger construction project, the simultaneous setting of a large number of tanks is required, this means a considerable saving of time.
  • the fitter then only needs to connect a device having the switch, in particular a hand-held device, which preferably also has the means for power supply for driving the limit switches, to the relevant control cable-side coupling part and can carry out the adjustment work at the push of a button. With the same simple success it is also e.g. possible to easily adjust a large number of awnings on exactly the same extension length on a long window front.
  • the drawing shows a characteristic of the invention and essential section of a tubular motor in a schematic representation.
  • the winding tube intended for winding up the shell or the awning fabric is designated by 10. It sits with its two ends on a sleeve 11, of which the second sleeve, not shown in the drawing, can be driven in rotation by the winding motor, which is also not shown. By rotationally fixed connection of the winding tube 10 to the bushing 11, the bushing 11 can also be driven in rotation.
  • All other essential parts of the tubular motor are arranged in an inner tube, the motor tube 12. These parts initially consist of a threaded spindle 13 on which a switching element 14 with a section 15 is mounted as a traveling nut.
  • the rotary drive of the threaded spindle 13 for this purpose takes place via the rotary movement of the winding tube 10 and the bush 11 in that an internal toothing 16 arranged in the bush 11 meshes with a pinion 17 connected in a rotationally fixed manner to the threaded spindle 13.
  • the switching element 14 thus moves proportionally with the rotational movement of the winding tube 10 along the spindle 13.
  • buttons 18 and 19 are provided, which are attached to switch carriers 20 and 21 and the switching element 14 be actuable buttons are attached with 22.
  • both buttons are in the same plane in the exemplary embodiment, to which the threaded spindle 13 also runs parallel.
  • the switching element 14 acts on one or the other button 22 the winding motor is disconnected from the voltage source, that is to say switched off, by means of a switch (not shown).
  • Each of the two switch carriers 20 and 21 is seated on its own rotationally drivable threaded spindle 23 or 24, along which it can be adjusted together with the associated switch 18 or 19.
  • each switch is secured against rotation about the axis of the associated threaded spindle by suitable measures, for example in that it is guided on a guide rod at a distance from the associated threaded spindle.
  • the arrangement is simplified so that the switch carrier 20 adjustable by the threaded spindle 23 is slidably guided on the second threaded spindle 24 arranged parallel to the threaded spindle 23, while the switch carrier 21 movable by the threaded spindle 24 is correspondingly non-rotatably guided on the threaded spindle 23.
  • a separate drive 25 and 26 is provided for the rotary drive of each threaded spindle 23 and 24.
  • These drives consist of small direct current motors 27 and 28.
  • a sub reduction gear 29 or 30 Between each drive 25 and 26 and the associated threaded spindle 23 and 24 there is also a sub reduction gear 29 or 30.
  • the components described so far including a polygon 33 held in a fixed and stationary manner as a torque support, are located within a box 34 indicated by dash-dotted lines, provided that the tubular motor is used to drive a roller shutter, in which a roller shutter box is usually provided.
  • the electrical connecting wires in the exemplary embodiment both those for the power supply of the direct current motors 27 and 28 and for the winding motor are summarized in a control cable 35 which is led out on an end face of the tubular motor.
  • a coupling part 36 is attached to the end of the control cable 35.
  • This is a half component of a plug-in coupling 38 completed by a mating coupling part 37.
  • the coupling part 37 e.g. a diode plug is assigned to a hand-held device 42, which is equipped via two change-over switches 43 and 44 for independent control of the two motors 27 and 28, which can be changed by reversing the polarity, and in the exemplary embodiment has a receiving compartment 45 for batteries for the voltage supply of these motors.
  • the coupling part 37 is connected to the handheld device 42 via a cable 46 of suitable length.
  • the fitter can move the two switch carriers 20 and 21 independently of one another, but also together in the two possible directions by remote control, by actuating the change-over switches 43 and 44. For this purpose, he can take a position, even outside the building, that gives him a good overview of the roller shutter or awning movement.
  • the plug-in coupling 28 is disconnected again; the handheld device 42 remains with the assembler to prevent improper manipulation.
  • the battery compartment 45 in the handheld device 42 can also be used to hold, for example, a power supply unit instead of holding batteries.
  • the coupling part 36 need not be provided on an installation device 39, although this is perceived as being particularly practical. For example, it would also be possible to fasten it at a location that is largely hidden from the eye, for example on the inner outer wall of the roller shutter box 34 at the location designated by 47. If the hand-held device 42 is then equipped with a corresponding long cable 46, the coupling part 37 is plug-connected at 47 to the mating coupling part 36 located there. For the fixed accommodation of the coupling part 36, however, any suitable place in a room can be selected, which is a considerable advantage of the invention.
  • the servomotors 27 and 28 could also receive their power supply, for example, directly from the mains via a transformer installed in the installation pipe 12, for example, so that the hand-held device itself would then contain no voltage source. Then, however, each tubular motor would have to be equipped with a transformer, whereas with the integration of the voltage supply in the hand-held device only one hand-held device for Ar working on countless tubular motors would suffice, since the hand-held device is intended for the fitter who has to look after a large number of tubular motors.
  • the adjustable arrangement of the switch carriers 20 and 21 can also be carried out on two coaxial threaded spindle sections instead of on two parallel threaded spindles e.g. in the manner of DE-OS 31 31 316.
  • the drives 25 and 26 as well as the gears 29 and 30 and the directional clutches 31 and 32 could be arranged on one and on the other side of the spindle arrangement. It is also conceivable for the drives to act alternately on one or the other rotating spindle using a clutch.
  • small direct current motors for the drives of the type in question here can be obtained very inexpensively and also the gears only need to consist of two differently sized gears in a corresponding grouping, the double drive arrangement is quite advantageous.
  • the drawing does not show the possibility of also carrying the conductors for the power supply of the winding motor in the control cable 35.
  • the advantage of an extremely simple electrical installation is particularly evident in the arrangement of the coupling 36, which is recorded in the drawing, because in this case all the supply lines in the device 39 must be connected.
