    The present invention relates to an automatic flag hoisting system which comprises an endless string in the form of a flag line with mounted flag, at least one capstan, a motor, a power steering and a box structure to contain the flag when disassembled. . There are examples in the patent literature of automatic systems for setting up and taking down flags. One such example is set forth in South Korean Patent Specification No. KR101645986. Here, a flagpole is described which includes a hoisting device capable of setting and lowering the flag automatically at the desired times. The flagpole has a flagline that should lift the flag on one side of the flagpole. The flag hoisting system lowers or lowers the flag by automatically pulling on the drawbar and is provided on one side of the lower part of the flagpole. The automatic device includes a motor having a rope pulley installed to be in contact with the central part of the towline, and a control unit for hoisting or lowering the flag by controlling the direction of rotation of the rope pulley by controlling the current supplied to a motor, using a power supply unit. The control unit sets up and lowers the flag by controlling the current supplied to the motor to suit the time required to set and lower the flag.
    Another example of an automatic flag raising and lowering apparatus is described in U.S. Patent Application No. US2008121167. Described here is an electrically operated device for setting up a flag on a flagpole and later lowering the flag into a safe storage box. The apparatus described enables these steps to be performed remotely or automatically using electrically operated drive devices. The appliance can be operated remotely, for example from home
    DK 2019 00208 A1 2 or from an office, which makes setting up and taking down the flag easier. In addition, the device can be controlled by means of a timer or a light sensor. The flag's access to the storage box is achieved by the system comprising a lid which is opened and closed as required. However, this solution complicates the construction and control. The object of the present invention is to provide a simple and inexpensive system in which a high degree of certainty is obtained that the flag line is precisely controlled so that it does not slip or go into contact, and it must also be ensured that the flag is not filtered together or strikes knots on itself, or the tips of the flag get stuck. It is also an object that such an automatic flag hoisting system should be able to be used for an ordinary slightly conical flagpole.
    According to the present invention, an automatic flag hoisting system of the above kind is characterized in that the motor is connected to one end of a cylinder, which the flag line, which is passed several times around the cylinder, is simultaneously wound up on and off when the cylinder is rotated by the motor in one or the other direction, and the cylinder is connected at its other end to a cylindrical threaded piece enclosed by a fixed nut and having a threaded pitch corresponding to the thickness of the flagline. In this way, precise control of the flag line is ensured with a small risk of operational disturbances occurring that require repair personnel to be called. When the flag line is passed several times around the cylinder, the risk of the line slipping becomes minimal.
    In a preferred embodiment of the invention, the nut is fixedly mounted on a rail system which controls the cylindrical parts in such a way that only longitudinal movement is allowed, and on
    DK 2019 00208 A1 3 The rail system is also fitted with a pulley system that controls the flag line when it is rolled off or on the cylinder. This provides additional security for a well-functioning system with very little risk of the flag line filtering or going into trouble. According to one aspect of the invention, a guide bar is attached to the lower part of the flagpole, which is preferably located immediately above a guide tube for the flag.
    This ensures that the flag goes down correctly in the storage box, and the risk of the flag getting stuck or filtering together is significantly reduced.
    It is advantageous that the handlebar is made of metal with two arms, which are placed vertically on each side of the flagpole, and which are connected to a piece of flexible plastic hose which extends upwards along one side of the flagpole.
    This achieves both the strength (from the metal arms) and the flexibility (from the hose section) that is necessary for an optimal function of the handlebar.
    In the preferred embodiment, the handlebar is attached to the flagpole with a clamp, and it is formed with a distance between the arms of 300 - 400 mm, and the arms and the flexible hose piece have a diameter of approx. 50 mm.
    This achieves good control in relation to most flag sizes.
    DK 2019 00208 A1 4 In a further advantageous embodiment, an upper ring with an inner diameter corresponding to the diameter of the slightly conical flagpole approximately around the middle is passed around the flagpole. This ensures that the flag and the flag line are kept close to the flagpole, even when strong gusts of wind occur. In the preferred embodiment, the upper ring extends between 270 and 360 degrees and more advantageously between 300 and 350 degrees.
    It has been found that when a distance is created between the ends of the ring so that they do not reach completely together, there is a minimal risk of the ring getting stuck on the flagpole.
    It has also been found advantageous for the upper ring to comprise a central metal ring provided with roller elements in the form of balls or short cylindrical elements with through holes.
    In this way, it is ensured that the ring moves easily on the flagpole, and the risk of it getting stuck is further minimized.
    The invention will be explained in more detail below with reference to the drawing, in which Figs. Fig. 1 shows an overview view, seen from the side, of an automatic flag hoisting system according to the invention, Fig. 2 shows the storage and technical room, seen from above, 3 shows a section through the storage and technical room, which is located under the flagpole, seen from the side,
    DK 2019 00208 A1 Fig. 4A-D show a control bar for placement on the flagpole, Figs. 5 shows a guide ring placed around the flagpole. Referring now in particular to FIG. 1 to 3, where the reference numeral 10 shows an automatic flag hoisting system according to the invention. Reference numeral 1 denotes a flagpole which is of the slightly conical type commonly used. The flagpole 1 is mounted on top of a box structure 2, which should preferably be able to carry the flagpole 1, and which contains a cavity 3 in which a flag can be stored when it is not set. In addition to a flag (not shown), the cavity 3 also contains the technique necessary for raising and lowering the flag, which will be described in more detail in the following. On the flagpole there are approx. A guide bar 5 is mounted 2 m above the ground. In addition, a guide ring 6 (see Fig. 4) is applied around the flagpole, the function of which will be described in more detail in the following. The box construction 2 contains a first capstan 7 and a second capstan
    Above this runs a flag line 9, on which a flag is mounted as part of an endless string, which is constantly kept tightened by a spring-loaded tensioning system 4. The flag hoisting system 10 further comprises a cylindrical part 11, which at one end is connected to a also cylindrical part 12, which is provided with threads, the thread pitch substantially corresponding to the thickness of the flag line 9. At the other end of the cylindrical part an electric motor 13 is mounted. The construction of the cylindrical parts 11 and 12 and the electric motor 13 is slidably mounted on a rail 17, where a nut 14 is fixedly mounted. A pulley system for controlling the flag line is mounted next to the cylindrical part 11. Below the guide bar 5 a lowering tube 15 for the flag is shown, and the lowering tube 16 comprises a movable lid 15, which opens when the flag is raised or lowered.
    DK 2019 00208 A1 6 Fig. 4 AD shows views of a handlebar 5, which comprises two arms 21 and a piece of flexible hose 22. The arms are mounted on a clamping bracket 23, which is placed around the flagpole 1 and which can be clamped thereon by means of a bolt system 24. As it can be seen from Figs. 4B, the flexible hose 22 is placed close to the flagpole 1, and in this way it ensures that a flag is stretched out before it is subsequently lowered into the downcomer tube 15. The relatively large diameter of the hose and the hoop (approx. 50 mm) also ensures , that there is little risk of the flag getting stuck. As previously mentioned, the handlebar 5 can be placed approx. 2 m above the ground, but the exact location can be adjusted to ensure that the flag does not reach the ground when lowered.
    FIG. 5 shows a view of the guide ring 6, which is preferably made of a ring 26 of metal extending at an angle of less than 360 degrees, as the risk of it gripping the flagpole is thereby minimized. At the same time, the guide ring 6 is provided with small separate pipe pieces 25 or balls with a through hole of plastic, which makes it easy to move up and down on the flagpole 1. A through hole is shown in one of the pipe pieces 25, through which the flag line is passed. The guide ring 6 ensures that the flag line and thus the flag is kept close to the flagpole 1. This is especially important when the wind is strong and bumpy, as otherwise there will be a risk that the flag line, if the wind suddenly lies off, may become slack, whereby it may fall off a capstan or be filtered together.
    The function of the device is as follows. When a flag is to be set, the motor 13, which rotates the cylinder 11 around which part of the flag line is wound, is activated. This pulls on the side of the flag which is to end at the top of the flagpole, while the flag line is lowered for the side of the flag which is to end at the bottom by unwinding the line from one end of the cylinder at the same rate as the line is wound up. in the other end. The top side then moves around the first capstan and up from the box structure, which
    DK 2019 00208 A1 7 the flag is stored in when it is taken down and the lower side follows. Then the upper side reaches the handlebar 5, which is fixedly mounted on the flagpole, and the flag is pulled through through the handlebar 5 and up to the guide ring 6, which is gripped by the top of the flag and follows the flag up when it is set and when the flag is lowered. the size of the inner diameter means that the guide ring 6 remains on the flagpole 1 approx. halfway up. The top guide ring is then pulled up to the top, and when the flag is at the very top, the engine is stopped. By winding the flagline on and off at the same pace, it is ensured that the flagline is kept fairly tight, but in addition the flagline can be further tightened by means of a spring-loaded tension roller 4. Removal of the flag takes place by starting the motor 13 in the opposite direction of rotation. This pulls the flag downwards, and when it is approximately in the middle of the pole, the gradually increasing diameter of the flagpole leaves the guide ring at this point. However, it still works to hold the line close to the flagpole when the flag is pulled further down. When the flag reaches, for example, 2 m above the level at which the flagpole is mounted, it is pulled through the handlebar 5, which ensures that the flag is not double or otherwise folded. The guide bracket 5 functions to ensure that they are the ends of the flag which are tied to the flag line 9, which is first pulled through the bracket, after which the free part of the flag follows. Then the flag is pulled down a tube 15 and then down into the cavity 3, and the electric motor 13 stops when one half of the flag extends over the upper part of the area between the two capstans 7 and 8, and the other half is located in the lower part of the area. In this way, the flag hangs relatively freely and can dry quickly, reducing the risk of it being grounded. As previously mentioned, the cavity 3 in the box 2 can also be provided with a fan, a heating element or a dehumidifier to further ensure that the flag is kept dry.
    The system comprises an electronic control, which is preferably connected to a mobile network, so that the setting up and lowering of flags can be controlled by means of a
    DK 2019 00208 A1 8 mobile phone.
    The control can also take place via the Internet or by means of pre-loaded programs that, for example, adjust set-up and take-off times in accordance with the length of the day.
    In addition, the take-up and take-off time can be controlled by a light sensor, which measures the light intensity.
