Definitions

  • the object of the invention is a unit comprising a flagpole, a sheave, a halyard and a flag raising and lowering device for raising the flag up the flagpole and for lowering the flag, the said flag raising and lowering device comprising a driving motor, whereby
  • Flags are usually raised and lowered manually. Taking care of this task is, however, nowadays often inconvenient, because housing corporations no longer engage persons who would see to it. This is why maintenance companies usually take care of flag raising and lowering. Even for maintenance companies, however, the task is arduous as manual work, because one maintenance person will not have time to manage very many locations. This means that flag raising and lowering are often delayed. This service is, in addition, expensive for housing corporations.
  • US patent no. 3,417,732 also discloses an automatic flag raising and lowering device.
  • the flag moves inside a tube, which is located outside the flagpole.
  • the flag is fixed to a sleeve-like part, which is towered into a space between the tube located at the bottom of the pole and the pole.
  • This equipment is also unsuitable for use with old flagpoles.
  • Another disadvantage of the construction is that the tube attached around the flagpole is supported only at its lower end. The durability of such a support is poor.
  • the aim of the present invention is to eliminate the above-mentioned problems and to achieve a novel flag raising and lowering device, which can also be used with old flagpoles.
  • the flag raising and lowering device relating to the invention makes it possible to automate all existing flagpoles.
  • the flag When the flag is towered, it is pulled by means of a driving motor inside the separate protective tube located at the lower end of the flagpole, and when raised, the flag is pulled out of the protective tube.
  • Figure 1 shows a flagpole 10, to which the separate flag raising and lowering device 11 relating to the invention is connected as an accessory.
  • the device 11 incorporates a protective tube 12 and a driving motor 13.
  • the halyard forms a closed loop, which runs via sheaves located at the upper and lower ends of the flagpole 10.
  • the halyard 15 is passed via the protective tube 12 of the accessory 11 to the sheave 14 of the driving motor 13 of the accessory.
  • the halyard 15 is passed in the usual manner via the flagpole's own sheave 17, which is located on the finial 16 of the flagpole 10.
  • the flag 18 connected to the halyard 15 can be raised or lowered.
  • the flag 18 is pulled inside the separate protective tube 12 located at the lower end of the flagpole, on the side of the flagpole, and when raised, the flag is pulled out of this protective tube 12.
  • a lead-through 23 is fitted, which prevents the entry of water and snow inside the protective tube 12 at least for the most part.
  • the flag raising and lowering device 11 is a separate accessory unit, which can be installed even afterwards on an old flagpole 10.
  • the lower end of the protective tube 12 and the driving motor 13 housing are connected to the flagpole 10, for example, by means of the same bolts 24 with which the flagpole itself is fixed to its base.
  • the protective tube 12 is fixed to the flagpole 10 by means of a band 25.
  • the flag 18 has been lowered by means of the flag raising and lowering device 11 of figure 1. It can be seen in the figure that the flag 18 has been lowered. This has been done by pulling the halyard 15 by means of the sheave 14 rotated by the driving motor 13 so that the flag 18 has been lowered inside the protective tube 12 on the side of the flagpole 10. Similarly, the flag 18 may be raised by rotating the sheave 14-in the other direction.
  • Figure 3 shows a diagrammatic view of the halyard 15 control mechanism.
  • control elements which the control mechanism sensor 19 detects. These are, for example, small pieces of metal, which can be detected by a metal detector.
  • the halyard 15 has three control elements.
  • the control mechanism operates so that when the control element 20 for the upper position is at the sensor 19, the flag 18 is in its upper position, that is, at normal flag height on the flagpole. When the following control element 21 is at the sensor 19, the flag 18 is at half-mast. Similarly, when the control element 22 for the lower position is at the sensor 19, the flag 19 is lowered, in other words completely inside the protective tube of the device relating to the invention.
  • the equipment is capable of detecting whether the flag is in the upper position, at half-mast or in the lower position, and therefore of controlling the operation of the device.
  • a step motor can be used to move the halyard, in which case control elements attached to the halyard and sensors to detect them are not necessarily required.
  • a timing mechanism which raises and lowers the flag according to a desired schedule, may also be connected to the driving motor 13. It is furthermore possible to add a hot-air fan to the driving mechanism of the device, which fan dries the flag in the protective tube if wet. At the same time the fan prevents the halyard and flag from freezing in winter.
  • the hot-air fan can be programmed so that it heats the flag, the halyard and other equipment for a desired time subsequent to the flag having been lowered, and similarly also for some time before the flag is raised.
  • a unit comprising a protective tube outside the pole and a housing with the driving mechanism and control devices, is connected to the flagpole.
