Description

[0001] Hoisting device for hoisting flags, arrangement with such a hoisting device and method for manufacturing such an arrangement

[0002] The present disclosure relates to a hoisting device for raising flags comprising at least one of the following components:

[0003] - a sled for attaching a flag

[0004] - a masthead for attachment to a mast tube with at least one deflection device

[0005] - a pulling device, preferably a halyard.

[0006] Furthermore, the present disclosure relates to an arrangement comprising a mast tube and such a hoisting device and a method for manufacturing such an arrangement.

[0007] In prior art hoisting systems, the mast tube of a flagpole is always an integral part of the hoisting system. For example, rope openings and / or hatches must be milled into the mast tube, and holes must be drilled for fastening screws so that mechanisms such as winches, rope clamps, pulleys, slide rails, and crank systems can be attached outside or inside the mast tube.

[0008] There are also special mast tubes with profiled cross-sections, for example with guide recesses such as guide grooves or with guide elevations such as guide ribs, in or on which sliding pieces can slide along the mast tube profile.

[0009] Therefore, flagpoles, and consequently the entire mast, are complex, expensive, and resource-intensive to manufacture, install, and maintain. With flagpoles that have rope openings in the mast tube, the rope must be pulled out through a small opening and then, after raising a flag, threaded back through the same opening. Furthermore, these openings require a closure, typically a cover with a cylinder lock and locking mechanism. Changing a flag on conventional flagpoles is time-consuming and / or requires trained personnel. Therefore, operating a flagpole is time-consuming, user-unfriendly, and cumbersome.

[0010] Flagpoles with rope openings are significantly weakened in the area of ​​the opening for the rope handle. To prevent breakage under stresses such as varying wind speeds, manufacturers insert additional steel tubes inside the mast at the level of this weakened area. Therefore, such flagpoles are either prone to breakage and other damage and / or even more complex to manufacture, install, and maintain.

[0011] Aluminum profiles for profiled mast tubes are usually imported in large batches and processed externally for the respective configuration. This incurs costs for processing and transport. Furthermore, various lengths must be kept in stock. This results in pricing, time, logistics, and other problems.

[0012] The prior art includes, for example, documents ES 2345970 A1, CN 103510741 A, and US 2007 / 220790 A1, all of which disclose flagpoles in which the mast tube is an integral part of the hoisting device and which exhibit the aforementioned disadvantages. The purpose of the present disclosure is therefore to at least partially overcome the disadvantages of the prior art and to disclose an improved hoisting device compared to the prior art, which is characterized in particular by simplified operational readiness. The purpose is further to disclose an arrangement with such an improved hoisting device and a method for manufacturing such an improved hoisting device.

[0013] This problem is solved by the features of claims 1, 12 and 15.

[0014] This problem is solved by means of a hoisting device according to claim 1, namely a hoisting device for hoisting flags comprising at least one of the following components:

[0015] - a slide for attaching a flag, preferably detachably - a masthead for attaching to a mast tube, preferably detachably, with at least one deflection device

[0016] - a pulling device, preferably a halyard,

[0017] wherein a first end region of the traction element is connected or connectable to the carriage and at least a middle region of the traction element is connected or connectable, at least partially, to the at least one deflection device of the mast tip, preferably detachably, wherein a second end region of the traction element is connected or connectable to at least one counterweight, preferably detachably, and the second end region with the at least one counterweight is designed for arrangement within the mast tube.

[0018] A pipe can be an elongated hollow body.

[0019] The cross-section of a tube, transverse, preferably orthogonal, to its longitudinal extent, can be at least partially or completely round, preferably circular or oval, and / or angular, preferably rectangular, square or polygonal. A mast tube is a tube that can be a component of a flagpole.

[0020] The terms "releasable connection," "releasably connected," and "releasably connectable" can be understood to mean that at least two originally separate components can be connected, and that this releasable connection can subsequently be undone non-destructively, so that the at least two components are once again in their original separate state, ready to be reconnected. "Releasable connection," "releasably connected," and "releasably connectable" can therefore also be described as "non-destructively releasable connection," "non-destructively releasable connection," and "non-destructively releasable connection."

[0021] The terms “removable fastening”, “removably fastened” and “removably attachable” can be understood analogously to the above explanation as “non-destructively removable fastening”, “non-destructively removable fastening” and “non-destructively removable attachment”.

[0022] The masthead is usually attached to one end of the mast tube to utilize the entire length of the tube for hoisting the flag. Alternatively or additionally, it may be possible to attach the masthead at any position between the two ends of the mast tube.

[0023] A hoisting device disclosed here already incorporates means for hoisting a flag and can be easily, quickly, and conveniently attached to any length of mast via the masthead, thus making the flagpole equally easy, lightweight, and quickly ready for use. Such a hoisting device requires no modification of the mast tube or the rest of the flagpole, making the production of the mast tube, and therefore the flagpole, less complex, cheaper, and more resource-efficient. For the same reasons, the commissioning and maintenance of the flagpole are also improved.

[0024] Two advantageous designs can be achieved by attaching the mast tip to the mast tube and arranging the second end area with at least one counterweight inside the mast tube.

[0025] On the one hand, the mass of the counterweight, and thus its associated gravitational force, can be designed such that the carriage, with and / or without a flag, can be pulled to the top of the mast by the pulling force of the traction device. In this case, the pulling force is transferred to the carriage by means of the traction device, as the counterweight's gravitational force is redirected by the deflection mechanism. In this way, a flag can be hoisted automatically, since the counterweight's gravitational force moves the counterweight away from the top of the mast within the mast tube and pulls the carriage along the mast tube to the top. This is therefore a mechanical raising device for the automatic hoisting of flags.

[0026] On the other hand, the mass of the counterweight, and thus its associated gravitational force, can be designed such that the carriage, with and / or without a flag, remains at a constant height due to the pulling force of the traction element. This is because the gravitational force of the carriage, with and / or without a flag, and the gravitational force of the counterweight, which are connected to each other via the traction element and the deflection device (preferably detachably), balance each other. In this way, a flag change can be carried out in a user-friendly manner, since the carriage remains at the height of the flag change, for example, chest height of a person and / or in the lower end of the mast tube, without having to expose or unlock an opening in the mast tube and without having to clamp the traction element inside the mast tube.Such a hoisting device can particularly preferably be combined with a telescopic pole and / or with an electrically controlled drive for hoisting a flag and / or changing a flag, as will be described in more detail later.

[0027] Therefore, operating a flagpole is more time-saving, user-friendly and simple for one person.

[0028] Since no openings or other machined areas in the mast tube are necessary, such a hoisting device reduces the risk of breakage or other damage to the mast tube or flagpole and the need to additionally support or secure machined areas.

[0029] Furthermore, a flagpole with such a hoisting device is advantageous in terms of manufacture, storage, commissioning and / or maintenance, as it reduces manufacturing costs, facilitates the storage of parts or flagpoles as a whole, and allows the combination of a hoisting device with different mast tubes, especially mast tubes of different lengths.

[0030] For the sake of completeness, it should be noted that in the course of describing this disclosure, the numerical words used, such as one, two, three, and the like, generally only describe the minimum quantity of a feature of the disclosed hoisting device. Individual features or components may, of course, be present in larger numbers. For example, disclosed hoisting devices may have more than one carriage, more than one masthead with more than one deflection device, etc. In this sense, the numerical word "one" should, where appropriate, be understood to mean at least one, etc.

[0031] All value ranges specified here with closed ends, for example between A and B, and with open ends smaller or larger than C, expressly include all ranges that fall within or are nested within these ranges. For example, a disclosed range between 1 and 10 is understood to include, among others, ranges between 2 and 10, between 1 and 9, between 3 and 9, and so on. Furthermore, the specified value ranges are to be understood as closed intervals whose boundaries, i.e., end values, also belong to the interval. In the example above with the range between 1 and 10, the value 1 and the value 10 are therefore also part of the range.

[0032] As used herein, the expressions "at least one of A, B, C", "at least one of A, B and C", "at least one of A, B or C", or "group of A, B and / or C" each mean one of A, B or C, or any combination of A, B and C. For example, "at least one of A, B and C" can include only A, only B, only C, A and B, A and C, B and C, or A, B and C.

[0033] The terms "indissoluble connection", "indissoluble connection" and "indissoluble connection" can be understood to mean that at least two originally separate components can be connected together, whereby this indissoluble connection cannot subsequently be dissolved without damaging the integrity of at least one of the at least two components and / or without making it more difficult or impossible to reconnect the at least two components.

[0072] Furthermore, protection is sought for an arrangement comprising a mast tube and a hoisting device disclosed herein, wherein the hoisting device is preferably detachably connected or connectable to the mast tube.

[0073] An arrangement comprising a mast tube and a hoisting device can also be called a flagpole.

[0074] In a preferred embodiment of the arrangement, it can be provided that the mast tube is free of a guide recess, preferably a guide groove, along the mast tube and / or free of a guide elevation, preferably a guide rib, along the mast tube.

[0075] According to a preferred embodiment of the arrangement, it may be provided that at least one gripping device is provided for pulling down the carriage of the hoisting device along the mast tube, wherein the hoisting device is attached to the mast tube by means of the mast tip.

[0076] According to a preferred embodiment of the arrangement, the gripping device may have a telescopic mechanism for extending or shortening the gripping device and / or a gripping hook for the sled and / or for the flag and / or an additional weight to compensate for a pulling force of the counterweight and / or to lower the sled.

[0077] In a preferred embodiment of the arrangement, it can be provided that the gripping device, preferably the telescopic mechanism and / or the gripping hook, can be actuated electromechanically, electropneumatically and / or electrohydraulically.

[0078] If the gripping device is connected to the sled, including any flag on the sled, the weight of the gripping device, with and / or without an additional weight, together with the weight of the sled, can cause the sled to remain at its current position and / or height or to be lowered until the sled reaches the end of the mast tube opposite the masthead.

[0079] Furthermore, protection is sought for a method for manufacturing an arrangement disclosed herein, wherein a hoisting device disclosed herein is connected to the mast tube, preferably to an end of the mast tube, preferably detachably, and in the connected state the second end region of the traction element is arranged with the at least one counterweight inside the mast tube.

[0080] The following describes in detail an exemplary embodiment of a hoisting device disclosed herein, a flagpole with such a hoisting device and a method for manufacturing an arrangement with a mast tube and such a hoisting device.

[0081] The hoisting device can be placed on an open mast tube with a weight at the front and is thus immediately ready for use. The masthead, in particular a second module of the masthead, can be pressed into the open mast tube with slight force using vertical struts and clamped by the preload created by the slightly larger outer diameter of the struts compared to the inner diameter of the mast tube. Only a light clamping force is required. The hoisting device is now in place on the mast tube.

[0082] A digital compass enables return-to-home positioning to a starting position with slight clamping.

[0083] The hoisting device can comprise a first module and a second module. The first module can be movable, preferably rotatable, relative to the second module and radially supported by two large dustproof and waterproof shoulder ball bearings. Due to the free-standing counterweight inside the mast tube, it can be rotated in at least two directions, preferably in the horizontal plane.

[0084] A distance between the two shoulder ball bearings of 50 mm and 15 mm, preferably between 90 mm and 110 mm, can result in precise bearing operation with a long service life. Thanks to virtually backlash-free bearing operation, a constant gap between the carriage and the mast tube can be maintained, allowing the hoisting mechanism, especially the carriage, to rotate smoothly and / or silently around the mast tube without direct contact.

[0085] The sled can be balanced in such a way that it glides along the mast tube with almost no friction.

[0086] This is made possible by a counterweight in the rear part of the sled. The hole for attaching the traction element is the apex of a curve, where on one side of the apex there is, among other things, a boom profile of a flagpole and on the other side the mast tube and the part of the halyard device opposite the flagpole.

[0087] The weight on the part of the carriage opposite the flag boom can balance the weight of the boom profile and part of the flag, allowing the carriage to slide up and down along the mast tube without jamming.

[0088] Assuming the sled can be retrieved and hoisted with or without the flag, perfect buoyancy control is difficult to achieve. Therefore, jamming should be kept to a minimum.

[0089] It is also possible to neglect the weight of a dry flag.

[0090] The traction cable can be threaded through a hole in the carriage at one end and secured there. It can then be looped 540° around the deflection device and guided through the cable guide at the masthead. The counterweight, which is heavier than the carriage, the boom profile, and the flag combined, is attached to the other end of the traction cable.

[0091] The counterweight, which pulls downwards from the top of the flagpole, pulls the carriage, including the boom profile and flag, upwards outside the flagpole towards the top of the mast.

[0092] In this configuration, the carriage can come into contact with the masthead in its uppermost position, forming a positive-locking and / or force-locking connection along the longitudinal extent of the mast tube. For radial locking, one, preferably three, projecting outer cones on the carriage can engage with one, preferably three, inner cones in the masthead. This allows the carriage to be precisely aligned with the masthead.

[0093] Basically, the carriage and the mast tip can be aligned relative to each other by means of the traction element, with the cones serving for precise fine-tuning.

[0094] The possibility of logic app flag management still exists, as explained in more detail below.

[0095] A specially developed mobile app with a user interface can communicate with the microcontroller in the hoisting device via wireless radio connection, Wi-Fi and / or Bluetooth® and control the raising and lowering of a flag by means of a deflection drive.

[0096] Furthermore, it is possible to use a digital compass mounted on a control board, which uses the Earth's magnetic field to determine the current orientation of the masthead and the carriage relative to the cardinal directions and transmits this information to the microcontroller. This allows the masthead, specifically the first module, to be moved in a desired horizontal direction by means of a rotary drive. The hoisting device can fulfill all the necessary technical and electronic requirements for this purpose, such as program code that can be extended and modified according to customer specifications and wirelessly transmitted to the microcontroller via Wi-Fi and / or Bluetooth® for execution.

[0097] In a preferred embodiment, the control of the hoisting device may include a digital compass which can detect the current direction of the first module 4 and thereby bring the boom together with the flag into a predefined position and hold it in that position.

[0098] Thus, for example, it is possible to program a pause of, for example, 5 seconds every 100 cm when retrieving the flag.

[0099] The advantage of this is that the flag ribbons, which are usually attached to a flag every 100 cm and are placed around the mast tube, can be conveniently removed one after the other.

[0100] Precise positioning can be achieved by means of a slip-proof pulley design as a deflection device and an encoder on the deflection drive.

[0101] The end position and / or starting position of the carriage can be determined with the encoder and confirmed by a microswitch.

[0102] The microcontroller, e.g., the ESP32, can have 19 freely programmable inputs and / or outputs. The microcontroller can be programmed so that, for example, input 02 is checked during a specific action. For example, if you press "Raise" on the mobile app, the microcontroller will check input 02 with the corresponding program code. If this input is set to "High," no further action is initiated, because a "High" on this input could mean that the carriage is already in the uppermost hoist position and has activated a microswitch.

[0103] For smooth movements when raising and lowering the flag, a programmed acceleration and / or deceleration ramp can be used. The positioning of the masthead can be achieved analogously using the rotary drive with encoder.

[0104] A standstill monitoring system can be programmed using an encoder.

[0105] The advantage here is that if a drive is stationary, the encoder located on a drive shaft does not send any pulses. Therefore, it can be assumed that there is no wind.

[0106] If this condition is detected within a specific predefined time window, the rotary drive can return the flag in a predefined direction, e.g., southeast, so that the flag is clearly visible, for example, from the road that also runs southeast. This is a return-to-home positioning. The advantage of this is that it saves energy, since the capacity of the electrical energy storage system is limited.

[0107] It is therefore more advantageous to move to the home position, specifically the starting position, when there is no wind than to expend energy against the wind to optimize energy consumption. Furthermore, a flag should be able to align itself with the wind to prevent damage to the flagpole and boom.

[0108] When the flag is positioned facing the wind, the surface area exposed to the wind is minimized. In a preferred embodiment, it can be provided that in calm conditions the flag is returned to a desired position and / or starting position in order to avoid unnecessary energy consumption from the storage system.

[0109] In a preferred embodiment, the hoisting device can be designed to operate with the wind direction in order to optimize energy consumption.

[0110] In a preferred embodiment, it can be provided that the return of the boom including the flag to a desired position and / or starting position only takes place when the electrical energy storage device is fully charged.

[0111] With the hoisting device, a home position of 0-360° in a plane, preferably the horizontal, and a time window can be set via mobile app so that the flag repeatedly tries to align itself with the home position at certain intervals.

[0112] This is possible, among other things, due to the built-in digital compass of the hoisting device.

[0113] Since solar cells are expected to produce relatively low power outputs due to the small surface area of ​​the hoisting device, a separate motor driver can be provided for the rotary drive. This driver converts the rotational movements of the mast tip into electrical current and feeds it into the electrical energy storage system via a charge controller. It is therefore a generator.

[0114] A flag that constantly moves in the wind inevitably moves the masthead, much like an automatic wristwatch on the wrist, whereby the motor can become a generator and charge electrical energy storage.

[0115] It may be provided that a machine of the hoisting device takes over the function of a rotary drive and / or a generator.

[0116] The hoisting device is designed to simplify, shorten, and facilitate the process of raising and lowering a flag. For example, any inn could display its daily menu on the flag. Currently, this is very cumbersome and time-consuming with conventional hoisting systems, which is why it isn't common practice.

[0117] The return-to-home positioning is advantageous, but is only carried out depending on the charge level of the electrical energy storage, because raising and lowering the flags by the deflection drive is of greater importance and should be more reliably ensured.

[0118] The gearbox of the deflection drive can be geared in such a way that it is possible to manually retrieve the flag using a gripping device with a telescopic extension and attached gripping hook.

[0119] The weight, which is attached vertically to the pulling mechanism in the mast and pulls downwards by its own weight, allows the flag to be hoisted again independently and held in the uppermost position.

[0120] The weight can be heavier than the sled including the outrigger profile and flag.

[0121] Due to the calculated gear ratio at the deflection drive and the drive freewheel, the boom and flag cannot spring upwards as they would without resistance if the counterweight inside the mast tube pulled downwards, but instead rises slowly, even in the event of a total failure of the electrical energy storage system. Therefore, changing the flag from the ground is always possible.

[0122] The drive contacts (positive and negative) can only be energized during raising and lowering. In the normal state, the contacts can be left open so that the drive can be turned easily and without resistance.

[0123] The microcontroller can be put into sleep mode for a predefined period, e.g., from 11 PM to 5 AM, via program code and / or the mobile app. During this state and / or period, only microamps can be consumed, which in turn benefits the charge level of the electrical energy storage device.

[0124] Should it turn out that the electrical energy storage systems at the site are sufficiently recharged daily, many further actions are possible. For example, with appropriate program code, a series of hoisting devices and / or flags can be rotated at a predefined time and / or simultaneously, e.g., by 180°, preferably in calm conditions. Thus, the movement of one or more hoisting devices can be used for demonstration purposes or to attract attention.

[0125] The hoisting devices can communicate with each other wirelessly via Wi-Fi and / or Bluetooth®, preferably not continuously, but within a predefined time window to minimize energy consumption. A real-time clock module then triggers a simultaneous action. Alternatively, the flag can be lowered to half-mast by pressing a button on a mobile app. The mobile app also includes flag management with barcode and / or QR code scanning capabilities.

[0126] Each flagpole and / or each flag can be clearly identified by means of a barcode and / or QR code on one or more flagpoles and / or one or more flags.

[0127] Each flagpole can be assigned a geolocation, model, year of manufacture, height, and / or orientation of the boom. By scanning the barcode and / or QR code on the flagpole, it can be displayed in the mobile app and / or synchronized with a desktop version and integrated into Maps. Double-clicking on a selected flagpole in Maps provides all the relevant information at a glance, including a photo of the current flag.

[0128] Other desirable data such as actual time, due date of a flag change, lifespan, service life of a flag, time of last cleaning, last repair, stock of spare parts, flags and the like can be applied and set as a reminder or appointment with adjustable time intervals and alarms via pop-up.

[0129] The exemplary and detailed embodiment of a halyard device, a flagpole with such a halyard device, and a method for manufacturing an arrangement with a mast tube and such a halyard device, described so far, is not to be understood as limiting. Rather, this detailed embodiment is intended to describe the specific functions, advantages, and possibilities. Not all features described in this detailed embodiment are strictly necessary. Furthermore, features of other embodiments can be combined with this detailed embodiment. Similarly, features of this detailed embodiment can be combined with other embodiments.

[0130] Further details and advantages of preferred design examples are explained in more detail below with reference to the figure description and the drawings. These show:

[0131] Figs. 1 to 6: different views of a flagpole with an embodiment of a hoisting device disclosed herein;

[0132] Figs. 7 to 15: different views of the hoisting device from Fig.

[0133] 1 to 6.

[0134] Fig. 1 shows a perspective view from above of a flagpole 19 with an embodiment of a hoisting device 18 disclosed herein.

[0135] Fig. 1 shows an arrangement comprising a mast tube 15 and a hoisting device 18 disclosed herein, wherein the hoisting device 18 is preferably detachably connected or connectable to the mast tube 15.

[0136] Fig. 1 shows a hoisting device 18 for hoisting flags 17 comprising at least one of the following components:

[0137] - a sled 2 for attaching, preferably detachably, a flag 17

[0138] - a masthead 1 for attachment, preferably detachably, to a mast tube 15 with at least one deflection device 5, a traction element 10, preferably a halyard, wherein a first end region of the traction element 10 is connected or connectable to the carriage 2 and at least a middle region of the traction element 10 is at least partially connected to the at least one deflection device 5 of the masthead 1, preferably detachably, wherein a second end region of the traction element 10 is connected or connectable to at least one counterweight 8, preferably detachably, and the second end region with the at least one counterweight 8 is designed for arrangement inside the mast tube 15.

[0139] Fig. 1 shows the masthead 1, the carriage 2, a boom profile 16, an upwardly open mast tube 15 into which the masthead 1 is inserted, and a traction element 10, which connects the carriage 2 to the counterweight 8 via the deflection device of the masthead 1 and is a rope 10 in this embodiment. In Fig. 1, part of the mast tube 15 is cut out, through which the traction element 10, here the rope 10, and the counterweight 8 are also visible.

[0140] The mast tip 1, inserted into the mast tube 15, can be secured and locked against falling by a mechanism.

[0141] Furthermore, a hanging medium can be seen in Fig., which may be a flag 17 but does not necessarily have to be.

[0142] The suspended medium 17 can be attached to the boom profile 16 with clips. Flags typically have a hem and are slid onto the boom profile 16 and secured with a hook between the lateral tab on the medium and the eyelet on the carriage 2; see the latch 2.d in Fig. 4.

[0143] Fig. 2 shows a perspective view from below of the flagpole 19 from Fig. 1. In Fig. 2, the hoisting device 18 is shown with the slide 2 slightly lowered.

[0144] In Fi . 2, the movable first module 4 and the second module 3 of the masthead 1, which is firmly connected to the mast tube 15, can be seen.

[0145] Furthermore, as can be seen in Fig. 2, an opening 4. a for the charging socket 13. c, driver and outer cones 4.b and the traction element 10 attached to the carriage 2, which in this embodiment is a rope 10 .

[0146] In Fig. 2, the carriage 2 is lowered downwards by 200 mm towards the ground, whereby the counterweight 8 on the opposite side of the deflection device is deflected upwards approximately 200 mm towards the mast tip 1, which corresponds to a translation factor of 1 : 1 .

[0147] In the boom position shown in Fig. 2, the carriage 2 can be moved with a gripping device 14 and / or via a deflection drive.

[0148] The control unit can include a transistor such as a MOSFET, which allows the positive and negative poles of a hoisting device's drive to be connected, effectively acting as a drive brake. This enables the boom 16, along with the flag 17 and carriage 2, to be held in position with minimal current draw.

[0149] In a preferred embodiment, a motor and / or machine 7, preferably in the form of the rotary drive 7 and / or the generator, can reverse its positive and negative poles by changing its direction of rotation. This allows the control system to detect the direction in which the boom and flag are moving. This serves for motion monitoring. In another preferred embodiment, the hoisting device can have a mechanism in which the control system short-circuits the positive and negative poles of a motor and / or machine 7, preferably in the form of the rotary drive 7 and / or the generator, by means of an SMD relay and / or a transistor to brake the motor. This makes it possible to hold the flag in a desired position with low energy consumption.

[0150] Due to the upstream transmission of a geared motor, only a very small motor braking effect is required.

[0151] Since the weight forces of counterweight 8 on one side of the deflection device and the weight forces of sled 2, boom profile 16 and flag 17 on the other side of the deflection device at least partially or completely cancel each other out, the power consumption at the deflection drive can be kept very low.

[0152] Fig. 3 shows a perspective view from above of the flagpole 19 from Fig. 1, with the hoisting device 18 partially shown in an exploded view.

[0153] Fig. 3 shows the hoisting device with slightly lowered slides 2, mounted on cut mast 15, boom profile 16 including flag 17 and open masthead 1.

[0154] In the front area, you can see circuit board 13. a with the connections for electrical energy storage, solar cells for charging electrical energy storage, drives, especially electric motors, encoder inputs and sensor inputs.

[0155] Furthermore, Fig. 3 shows the microcontroller 13.b, suitable for wireless radio communication, Wi-Fi and / or Bluetooth®, mounted on circuit board 13.a, and the digital compass 13.e. The charging module with charging socket 13.c, a voltage regulator 13.d, a driver 13.f for the deflection drive 6, a driver 13.g with recuperation function for the rotary drive 7, a microswitch 13.h and a real-time clock 13.i are located on the back of circuit board 13.a and / or under the microcontroller 13.b and remain hidden in this illustration.

[0156] Following the control unit 13, the deflection device 5, including a pulley 5 driven by the deflection drive 6, can be seen. The deflection drive 6 comprises a geared motor with encoder 6.a, a toothed belt pulley and / or sprocket 6.b, a toothed belt pulley and / or sprocket 6.c on the motor shaft side, a toothed belt and / or chain 6.d on the pulley side, and an axle 5.a of the pulley 5.

[0157] The rope wheel 5 can serve as a deflection pulley and / or as a rope wheel 5 driven by the deflection drive 6, which is why a special design is required, which is explained in more detail in Figs. 7 to 15 including figure description.

[0158] At this point, it should be mentioned that the rope 10, coming from the counterweight 8 inside the mast tube 15, is wrapped twice around the profiled pulley 5, which has two grooves, and is brought through the opening 4.c in the mast top (see Fig. 4) into the opening of the carriage 2.c (see Fig. 4). The end of the rope protruding from the carriage 2 is knotted, which ultimately holds the carriage 2 in the recess 2.c at the knot.

[0159] On the carriage 2, one can clearly see three of the four inner cones 2.b, into which the outer cones 4.b engage towards the end of the hoisting process and align carriage 2 and masthead 1 to each other and connect them radially in a form-fit and / or force-fit manner.

[0160] The motor shaft of the rotary drive 7 is supported at its end by an additional bearing 9 to absorb and transfer radially occurring forces as effectively as possible. This ensures a longer service life for components such as the motor, gearbox, and gears.

[0161] Furthermore, the rope guide 5.b is attached at a 180° angle around the rope wheel 5. It is intended to guide the rope 10 in the grooves of the rope pulley 5 and prevent the rope 10 from crossing over and jumping out.

[0162] Fig. 4 shows a sectional view AA of the flagpole 19 from Fig. 1.

[0163] The complete hoisting device 18 is usually pre-assembled and placed on the open mast tube 15 with the counterweight 8 in front. The hoisting device 18 is then immediately ready for use.

[0164] The assembly process can be better described with the help of a later exploded view in Fig. 6.

[0165] The complete hoisting device 18 can be placed onto the open mast tube with the weight facing forward. The masthead 1, specifically the second module 3 of the masthead 1, can be pushed into the mast tube 15 until it stops by applying slight pressure to the hoisting device 18.

[0166] Since the outer diameter of the second module 3 of the mast tip 1, optionally including webs 3.g, is a few hundredths of a millimeter larger than the inner diameter of the mast tube, a backlash-free joint or even slight clamping can be achieved here.

[0167] The first module 4 with the ball groove bearings 9 will rotate radially rather than the slightly clamped second module in the mast tube 15.

[0168] The second module 3 is limited axially downwards by its stop 3. d .

[0169] It is not necessary to screw the hoisting device to the mast tube 15, since the weight forces act downwards towards the ground anyway.

[0170] A preferred feature is a supported, low-friction, endless rotation of the carriage 2 together with the boom profile 16 and flag 17, clockwise and / or counterclockwise, around the axis of the mast tube 15, without the carriage 2 touching the mast tube 15.

[0171] Figure 4 shows how the second module 3 is inserted radially and axially into the mast tube 15 in a form-fitting manner. Based on the precisely fitting and backlash-free second module 3, the first module 4 can also rotate without backlash about its axis via two large backlash-free ball bearings, which are designed as shoulder bearings 9.

[0172] The selected shoulder bearings 9 are suitable to handle the maximum radial and axial forces occurring in this device and to ensure long-term backlash-free bearing operation.

[0173] Based on the backlash-free rotation of the first module 4 around its axis and equally around the mast tube 15, the carriage 2 will also rotate without backlash around the mast tube 15, since this carriage 2, in the hoisted state, forms a positive-locking connection with the first module 4.

[0174] This is due, on the one hand, to the four outer cones 4.b on the first module 4, which engage in the four inner cones 2.b on the slide 2, and, from a radial and axial point of view, to the contact pressure of slide 2 against the first module 4 due to the deflected weight force of the counterweight 8.

[0175] Furthermore, the carriage 2 together with the boom profile 16 and flag 17 can slide along the mast tube 15 with as little resistance and friction as possible when the flag 17 is being retrieved and / or hoisted.

[0176] In section AA Fig. 4, the cantilever profile 16 is located to the left of the cable passage 2. c and the rear end of the carriage 2 is located at the far right. The cantilever profile 16 and the rear end of the carriage 2 can be approximately level in the area of ​​the cable passage 2. c.

[0177] The rear end of the sled 2 can be slightly heavier than the front end of the sled 2 including the boom profile 16, because there will sooner be a flag 17 on the boom profile 18 than none.

[0178] This is achieved by balancing according to the boom profile, using counterweights, e.g. in the form of sand or lead shot in cavities in the rear area of ​​the carriage 2. The most common boom aluminum profiles are 1 m and 1.5 m and depending on the size, a counterweight can be added or subtracted.

[0179] Since carriage 2 is located near the ground when the flag is being hoisted, the boom profile can be replaced with a different length and the weight adjusted from the ground. Since a flag fabric typically weighs up to 40 g / m² 2 Given the weight, the slight excess weight of the rear end of sled 2 can be disregarded.

[0180] The first module 4 can accommodate, among other things, four lithium-ion secondary cells as electrical energy storage units, each with a nominal voltage of 3.7 V and a capacity of 5,000 mAH.

[0181] In a 2S2P configuration, this results in a system voltage of approximately 6-8 V at 10,000 mAh.

[0182] An extension of additional secondary cells 12 e.g. pluggable to the first module 4, projecting downwards inside the mast tube, is possible.

[0183] To constantly supply the microcontroller 13. b with the required 3.7 V, a voltage regulator 13. d including conductor track layout can be implemented in the circuit board 13. a.

[0184] The circuit board 13. a and the conductor track layout can be designed in such a way that at least one or more or all of the control-relevant components can be accommodated on it.

[0185] This allows for shorter conductor paths and minimizes cable and / or connector contacts. Furthermore, the connections and / or cables can be limited to the electrical energy storage devices 12, solar cells 11, and drives with encoders located further away from the control unit.

[0186] In a preferred embodiment, it can be provided that the microcontroller on the control board 13 takes over the control of the hoisting device by storing the energy generated by a motor and / or the generator in the electrical energy storage device 12 and efficiently controlling the operation of the hoisting device.

[0187] In section AA in Fig. 4 it can be clearly seen that the digital compass 13. e and the motor drivers 13. f are located under the microcontroller 13. b for reasons of space.

[0188] Also visible in section AA are the recess for the rope knot 2.c, a crossbar for attaching the flag carabiner 2.d, rope opening 4.c in the first module 4, ball bearing 9 of the pulley 5, axle 5.a of the pulley 5, and the pulley 5 itself. In section AA, one can easily see the profile, the rope 10 wrapped around the pulley 5, the rope guide 5.b, which prevents the rope 10 from crossing over or jumping out, and the drive motor 6.a of the pulley 5.

[0189] Worth mentioning, and visible in section AA Fig. 4, are the overlaps and lugs of the housing parts.

[0190] These designs protect the ball bearings and electronic components in the masthead 1, specifically in the first module 4, from windstorms, rain, and other environmental and weather influences. This is particularly advantageous because hoisting systems are exposed to wind and weather 365 days a year and / or 24 hours a day.

[0191] Fig. 5 shows a view of the flagpole 19 from Fig. 1 with the section plane AA.

[0192] Fig. 6 shows an exploded view of the flagpole 19 from Fig. 1. In this exploded view, many components of the hoisting device 18 are shown with their corresponding position numbers.

[0193] The sled 2 can, as shown in Fig. 6, have at least one receptacle 2. a for, preferably, releasably attaching at least one flag boom 16.

[0194] As shown in Fig. 6, the first module 4 may have at least one gear 7.b for engaging with at least one, preferably internal, gear ring 3.c of the second module 3, wherein at least one relative movement, preferably a rotary movement in at least two directions, of the first module 4 relative to the second module 3 can be generated by means of the engagement of the at least one gear 7.b with the at least one gear ring 3.c, preferably wherein the at least one relative movement can be driven by a machine, particularly preferably by the rotary drive 7.

[0195] On the second module 3, bearing seats 3.e and 3.f can be provided.

[0196] On the carriage 2, one can see three or four inner cones 2.b in Fig. 6, into which the outer cones 4.b engage towards the end of the hoisting process and align the carriage 2 and the first module 4 to each other and connect radially in a form-fit and / or force-fit manner.

[0197] Furthermore, the following components can be seen in Fig. 6:

[0198] - a spacer sleeve 5. c for the deflection device 5, preferably for the rope wheel 5,

[0199] - Ball groove bearing 9. c for the movable bearing of the rope wheel 5,

[0200] - Ball groove shoulder bearings 9. a and 9. b for the bearing of the first module 4, which is movable relative to the second module 3; ball groove bearing 9. d for the deflection drive 6.

[0201] - a geared motor 7. a optionally with encoder, a gear 7.b and a motor mount 7. c for the rotary drive 7,

[0202] - a ball groove bearing 9. e for rotary drive 7,

[0203] - Circuit board 13.a with connectors,

[0204] - microcontroller suitable for wireless radio connection, Wi-Fi and / or Bluetooth® 13. b,

[0205] - Charging module with charging socket 13. c,

[0206] - Voltage regulator 13. d,

[0207] - Digital Compass 13. e,

[0208] - Driver for deflection drive 13. f,

[0209] - Driver 13.g with recuperation function for rotary drive 7, - Microswitch 13.h,

[0210] - Realtime Clock 13. i and

[0211] - Plug contacts 13. j

[0212] An additional weight, heavier than the counterweight 8 inside the mast tube 15, can be attached to the handle of a gripping device 14, which is not shown here.

[0213] Should it ever be necessary to change the flag manually, the carriage 2 with the boom profile 16 can be held in the lower position independently due to the higher weight of the gripping device and / or the additional weight, and the flag can be changed comfortably.

[0214] The basic principle is based on a type of pulley system with only one deflection pulley and one supporting rope.

[0215] The factor by which counterweight 8 and carriage 2 are moved in opposite directions is therefore 1:1. The counterweight 8, inside the mast tube 15, always pulls downwards with the force of gravity Fl. The rope 10 attached to the counterweight 8 is wound around the pulley 5, which is located at the top of the mast 1, and attached to the carriage 2 at the other end. Since the counterweight 8 pulls downwards on one side of the pulley with the force of gravity Fl, which is considerably greater than the combined force of gravity F2 of carriage 2, the boom profile 16, and the medium 17, the carriage 2, attached to the other end of the rope 10, is pulled upwards and always held in the uppermost position.

[0216] Several versions of the hoisting device will be available, namely a purely mechanical and / or an electromechanical hoisting device.

[0217] A more cost-effective, purely mechanical hoisting device features a deflection device 5 with a mechanical friction damper. This can, for example, be coupled to a pulley.

[0218] The friction damper can ensure a smooth, even hoisting process without the risk of the carriage 2 being pulled upwards too quickly and thereby damaging components of the hoisting device 18.

[0219] In this variant, a gripping device, preferably a telescopic pole, with an attached hook is used to retrieve the flag.

[0220] The weight of the gripping device, preferably the telescopic pole, can correspond approximately to the weight of the counterweight 8 inside the mast tube 15. Thus, the hook of the gripping device, preferably the telescopic pole, can be used to grasp the boom profile 16, the carriage 2, or a flag ribbon, and the carriage 2, along with the flag 17, can be retrieved.

[0221] Due to the approximately equal weight of the gripping device, preferably the telescopic pole, and the counterweight 8, the sled 2 is held in a retracted position close to the ground, thus leaving both hands free to remove or change the flag 17.

[0222] The advantages of a purely mechanical hoisting device are obvious: a very simple system with only a few components. There are no, or very few, potential sources of error and components that can break.

[0223] With both a purely mechanical and an electromechanical hoisting device, at least one of the following disadvantages is no longer necessary:

[0224] No special machining of the mast tubes is required, no rope gates or holes for fixings need to be milled into the mast tube, no rope clamps or crank mechanisms need to be fiddly mounted inside the mast tube through a small hole, no external ropes, pulleys, or guide rails exposed to the elements and requiring installation, and no additional stiffening of the mast tube with internal steel tubes in the area of ​​the rope holes. The rope openings in the lower part of the mast tube significantly weaken the mast tube, as a large leverage effect comes into play, for example, in windy conditions with a hoisted flag. To prevent buckling, manufacturers insert additional steel tubes into the mast tube. Therefore, this system is an efficient system that enables quick flag changes with low manufacturing costs and a low carbon footprint compared to conventional systems.

[0225] Currently, two people are required to raise and lower flagpoles, as the various pipes that need to be lifted from the base tube increase the workload, and raising and lowering flagpoles in windy conditions is dangerous. Furthermore, the design, including the use of internal or external ropes, cranks, or manual operation with rope clamps, results in poor user-friendliness. After raising the flag, several meters of rope usually have to be tucked back into a small opening in the mast, which is very time-consuming.

[0226] For the larger openings, an additional steel tube must be integrated inside the mast tube, because in this lower area where these openings are located, large forces can occur due to leverage, and these openings represent a weak point without an internal steel tube.

[0227] There are therefore many different systems with numerous components, which poses a logistical challenge as it becomes difficult to keep track of spare parts. This can lead to ropes shearing off and outrigger carriages hurtling to the ground, resulting in damaged carriages and requiring the entire flagpole to be hoisted out of the base tube. Even pebbles trapped between the base tube and the mast tube can make lifting it out impossible for two people. Additionally, there are small rope gates with various key systems, rope clamps that give way, and plastic rings on the carriages that jam against the mast tube during lowering and raising because the attachment points are too weak.These days, changing a flag and / or maintaining flagpoles requires a key ring with several keys, grinding tools, cutting and grinding discs, a drill set, a tap and die set, various open-end and ring wrenches, a cordless drill, a toolbox with Allen wrenches, Torx wrenches, ratchet set, cutter knife, various pliers, and a case full of spare parts for conventional systems.

[0228] In summary, changing a flag on conventional flagpoles with the usual hoisting devices or systems is time-consuming, user-unfriendly and inefficient.

[0229] Figs. 7 to 15 show nine different views of the flagpole 19 including the hoisting device 18 without mast tube 15, boom profile 16, flag 17 and counterweight 8.

[0230] Furthermore, in each view of Figs. 7 to 15, various components were hidden to reveal concealed elements.

[0241] In a preferred embodiment of the hoisting device 18, it can be provided that the mast tip 1 in the electromechanical variant houses solar cells 11, which feed the generated current into the electrical energy storage device 12 via a charge controller 13. c.

[0242] In a preferred embodiment of the hoisting device 18, the first module 4, in its electromechanical variant, may house the electrical energy storage device 12, the rotary drive 7, the deflection drive 6, the deflection device 5, and the control unit 13. In a preferred embodiment of the hoisting device 18, a motor 6a may be provided to move the rope wheel 5 clockwise and counterclockwise, thus automating the raising and lowering of the flag.

[0243] In a preferred embodiment of the hoisting device 18, it can be provided that the control of the motor 6. a and thus the movement of the rope wheel 5, subsequently of the carriage 2 and ultimately of the boom profile 16 including flag 17 is carried out via a microcontroller 13. b and motor driver 13. g .
