[0002] Device for attaching an advertising medium to a mast construction and mast construction with such a device

[0003] The invention relates to a device for attaching an advertising medium to a mast construction and to a mast construction with such a device.

[0004] Towers, masts, such as those of a construction crane, or power poles offer opportunities for the installation of highly visible advertising media, especially in urban areas or along busy (rural) roads. Therefore, both owners and advertisers can benefit from their use as advertising poles.

[0005] Devices for mounting advertising media on masts, in particular on the lattice masts of construction cranes, are known. For example, WO 01 / 16926 A1 shows various devices with an outer shell or sheathing of a mast. However, due to their construction, these devices are very heavy, which, in addition to the high construction, transport, and assembly costs, requires additional reinforcement of the mast, particularly with regard to stability. EP 1 405 294 shows a lighter device with an inflatable shell that is attached at the height of a mast. However, this device also requires reinforcement of the mast, since strong winds can exert high forces on the mast.Even if the air is released from the envelope in strong winds, the surface area exposed to the wind hardly decreases, since the envelope, when unfolded, clings to the masts due to the wind, which represents a significant safety risk.

[0006] It is therefore an object of the present invention to provide a device for attaching an advertising medium to a mast structure, which enables simple manufacture and assembly as well as safe operation without requiring additional reinforcement of the mast structure. It is also an object of the present invention to provide a highly visible advertising surface that can be retrofitted to a mast structure.

[0007] These objects are achieved by the subject matter of the independent claims. Advantageous embodiments are defined in the subclaims.

[0008] A first aspect of the invention relates to a device for attaching an advertising carrier to a mast structure, comprising: an upper guide fastening which can be fastened to an upper section of the mast structure; a lower guide fastening which can be fastened to a lower section of the mast structure or to a foundation of the mast structure; a guide element which can be connected to the upper guide fastening and the lower guide fastening in such a way that it is located between the upper and the lower guide fastening at a predetermined or predeterminable radial distance from the mast structure, in particular vertically and / or parallel oralong the master stretching direction; an upper support structure which can be brought into engagement with the guide element in order to be guided by means of the guide element; a lower support structure which can be brought into engagement with the guide element in order to be guided by means of the guide element; a lifting device which is designed to raise or lower the support structures; a connecting element which connects the upper support structure and the lower support structure in such a way that they can be raised or lowered together at a predetermined or predeterminable axial distance from one another, and an advertising carrier element which can be connected to the upper support structure and / or to the lower support structure in such a way that it extends at least partially between the upper and lower support structures.

[0009] Advantageously, the device can be used to easily attach a raisable and lowerable advertising medium to a mast structure. In particular, assembly of the device on site, i.e., to a mast structure that has already been erected and / or assembled, is possible. For example, the guide structure, in particular comprising the guide fastening and / or the guide element, can be retrofitted to an existing mast structure. This means that mast structures can also be equipped with the device only temporarily, or the device can be easily replaced. The guide element advantageously ensures that, even in strong winds, the support structures can be raised or lowered at a radial distance from the mast structure, i.e., without coming into contact with the mast structure, and guided along the direction of extension of the mast structure.

[0010] In addition, the device has few components and is lightweight, which is advantageous for production, transport, and assembly. The spaced-apart support structures, via the advertising carrier element arranged between them, provide the possible advertising space in which the desired information or advertising can be placed. The dimensions of the advertising space or the advertising carrier element are predetermined or can be predetermined by the length of the connecting element and / or by the configuration of the support structures.

[0011] Another advantage is that no modification and / or (additional) reinforcement of the mast structure is necessary, as the support structures can be lowered at any time, even in winds exceeding approximately 75 km / h. This significantly increases the site's potential.

[0012] A mast structure can be or comprise, for example, a mast or a tower. The mast structure can in particular be or comprise a substantially vertical, pillar-like structure. The mast structure preferably has a small footprint compared to its height. For example, the mast structure is or comprises: an antenna or transmission mast, a loudspeaker mast, a (power) transmission mast, a cable car support, a supporting structure of a tower (construction) crane, a (support) pillar. The mast structure can have a foundation or be attached to or with it.

[0013] The mast structure has a master extension direction substantially parallel to the direction of its greatest extension, for example, in the erected state, substantially vertically upwards. The master extension direction corresponds in particular to the axial direction of the mast, wherein a radial direction represents a direction perpendicular to this axial direction. An upper section of the mast structure is preferably positioned higher than the lower section of the mast structure compared to the ground and / or the earth's surface. An upper section of the mast structure can, for example, be a section of the mast structure with a height of approximately 5 m, 10 m, 20 m or more. A lower section of the mast structure can, for example, be a section of the mast structure with a height of approximately 0 m, 1 m, 2 m or less.

[0014] The advertising support element can provide an advertising surface that is positioned and / or can be stretched at least partially between the upper and lower support structures. The advertising support element can, for example, comprise an advertising foil and / or an advertising banner and / or an advertising panel and / or an advertising screen and / or another suitable advertising object with an advertising surface.

[0015] The advertising carrier element may, as described in detail below, also comprise an inflatable air cushion element which itself contains or represents the advertising space, or which is configured to tension and / or tighten an advertising carrier film or the like when inflated.

[0016] In the inflated state, the air cushion element is positioned at a distance from the mast structure and / or is not coupled to the mast structure in a force-locking and / or form-fitting manner. Due to the radial distance from the mast structure, the support structures can be moved at any time, even in strong winds. In other words, the upper support structure with the inflatable air cushion element can be displaced in the direction of the master extension when inflated. Compressing the air cushion element before moving, in particular lowering, the support structures is therefore not necessary, allowing for a faster response to changing environmental conditions, especially increasing wind speeds.

[0017] The advertising space may contain information, particularly advertising. For example, information may be printed, varnished, colored, and / or projected onto it.

[0018] The guide element can be rigid, such as a rod, a rail, or a bar. Preferably, however, the guide element is substantially flexible, such as a guide (wire) rope or a guide chain that can be tensioned between the upper and lower guide attachments. This is particularly advantageous with regard to manufacturing, transport, and assembly.

[0019] The guide element is preferably attached to the mast structure in such a way that the upper support structure and the lower support structure engaged therewith or guided thereby cannot come into contact with the mast structure. For example, the guide element is a guide (wire) cable that is substantially taut between the upper guide attachment and the lower guide attachment, so that it describes a substantially straight line at a substantially constant distance from the mast structure, even in high wind speeds.

[0020] The device preferably has two, three, four or more guide elements to ensure increased (pivoting) stability, in particular for absorbing moments of the support structure(s). The device preferably has a guide element at each corner of the mast structure, for example in the case of triangular or square mast structures. Each guide element can be fastened to the mast structure via its own upper and / or lower guide fastening. The guide fastenings can, for example, be designed to be fastened to the mast structure by screwing, clamping, or welding. However, the lower guide fastening can also be fastened to the foundation of the mast structure or to the ground, for example by means of a ground anchor or the like.

[0021] The upper support structure and the lower support structure can each have a coupling element for each guide element, via which they can be brought into engagement with the respective guide element.

[0022] The coupling element can be arranged radially inside on the upper or lower support structure.

[0023] The coupling element can be designed as a bearing.

[0024] The coupling element can be designed to guide the mutually movable parts of the guide element and the upper support structure or the lower support structure.

[0025] The coupling element can be designed to enable a relative displacement between the guide element and the upper support structure or the lower support structure in the direction of extension of the guide element and / or the mast structure and to restrict, in particular substantially prevent, a displacement orthogonal thereto.

[0026] The coupling element can be designed to be coupled to and / or engageable with a guide element already attached to the mast structure.

[0027] The coupling element can be a plain bearing or sliding bearing, which allows displacement in the direction of extension of the guide element or the mast structure and limits or prevents displacement in a plane transverse to the direction of extension of the guide element or the mast structure. Furthermore, the guide element is preferably arranged radially inward of the support structure and / or between the mast structure and the support structure. This enables a more compact guide attachment and / or better visibility of the weaving support element.

[0028] For example, a coupling element can be a (wire) rope guide sleeve through which the guide (wire) rope can be guided. The (wire) rope guide sleeve and the guide element can form a sliding bearing. The ends of the (wire) rope guide sleeve can be bent and / or widened, thereby achieving a low-wear guide. This design represents a particularly simple and cost-effective solution.

[0029] Alternatively, a coupling element can be or comprise a guide roller structure whose running surface comes into contact with the guide element, whereby the guide roller(s) can run along the guide element. Another alternative is a combination of a guide chain with a corresponding chain guide bearing.

[0030] The upper and / or lower support structure can comprise a rod system and / or one or more profiles and / or a framework structure. The upper support structure and the lower support structure can have a substantially identical or similar shape, particularly in plan view. Preferably, the upper support structure and the lower support structure can be mounted one above or below each other in such a way that, viewed in the master extension direction, the support structures substantially overlap.

[0031] Alternatively, one support structure can be larger in the radial direction than the other support structure, allowing a bumper to prevent possible contact with the advertising element by crane cables and / or to provide an advertising surface that is optionally inclined upwards or downwards. The upper and / or lower support structure can have or form a platform that, when attached to a mast structure, is essentially horizontally oriented.

[0032] Preferably, the upper support structure and / or the lower support structure surround the mast structure at least partially, for example, within an angular range of approximately 180°, and further preferably substantially completely, i.e., within an angular range of 360°. For this purpose, the upper and / or lower support structures can be constructed in multiple parts, allowing them to be arranged around the mast structure for on-site assembly and subsequently connected to one another, for example, by screwing.

[0033] The upper support structure is preferably designed to function as a support for electronics and / or devices for controlling and / or monitoring components of the device. This can be advantageous for manufacturing, transport, and assembly.

[0034] The lifting device for moving the support structure(s), in particular for selectively raising and lowering the support structures, preferably comprises: a lifting (wire) rope or a lifting chain, which is attached to an upper section of the mast structure, and a drive, for example a motor with a cable winch and / or chain winch and / or drum for winding / unwinding the lifting (wire) rope or the lifting chain. The lifting (wire) rope or the lifting chain can be attached to the upper guide attachment. This eliminates the need for additional brackets and / or attachments. Alternatively, a separate attachment is provided, which can be attached to the mast structure.

[0035] Alternatively, the lifting device can have one or more drivable drive rollers that can be coupled or engaged with the mast structure in such a way as to displace the support structure(s) along the mast's extension direction. The mast structure can serve as a rail along which the drive roller rolls or on which the drive roller is guided.

[0036] The lifting device can be connected to the upper support structure. In particular, the aforementioned drive of the lifting device, which is connected to the lifting (wire) rope or chain, can be mounted on the upper support structure. The lower support structure, however, can be connected to the lifting device only indirectly, namely via the connecting element, which simplifies manufacture and assembly.

[0037] The connecting element for connecting the upper support structure to the lower support structure is configured to limit the distance between the support structures substantially parallel to the master extension direction and / or to the axial direction of the guide element. In particular, the connecting element is designed to limit displacement of the upper support structure away from the lower frame structure.

[0038] The device can comprise a plurality of connecting elements, which are preferably arranged at substantially equal spacing from one another. For example, two, three, four, or more connecting elements can be provided, whereby the number of connecting elements can correspond to the number of guide elements.

[0039] Since the connecting element mechanically connects the upper and lower support structures, the lifting device only needs to be directly connected to one of the support structures to move both support structures together. If the connecting element is rigid, for example, as a connecting rod or connecting frame, the lifting device can also be directly connected to the lower support structure, since the connecting element can also transfer compressive forces to the upper support structure.

[0040] Preferably, however, the connecting element is a flexible connecting element, in particular a connecting (wire) rope and / or a connecting chain. This is particularly advantageous because, when the upper support structure is displaced upwards, a frictional connection between the support structures only occurs when the predetermined distance is reached or when the connecting element is tensioned. On the other hand, the upper support structure can be brought closer to the lower support structure, allowing the support structures, including the connecting element, to be easily compacted, for example, for transport and also during operation, for example, in high wind conditions.

[0041] The advertising support element preferably comprises an inflatable air cushion element, which is preferably connected to the upper support structure and, when inflated, extends from the upper support structure in the axial direction to the lower support structure. Such an advertising support element is easy to manufacture, transport, and assemble and enables the provision of a visually appealing and / or individually adaptable advertising surface. In particular, such an advertising support element is particularly lightweight, so that no reinforcement of the mast structure is necessary and / or the components of the device, in particular the support structures and the lifting device, only need to be designed for low loads. This saves resources and / or assembly effort. Furthermore, the device can be compactly stored and transported.

[0042] The air cushion element itself can serve as an advertising medium and provide the advertising space and / or serve as a tensioning element for an additional advertising film or the like.

[0043] The air cushion element is preferably attached to the upper support structure, in particular to its underside. The air cushion element can be inflatable and / or fillable with a fluid, in particular (ambient) air. In the inflated state, the air cushion element can extend and / or spread out towards the lower support structure. In the inflated state, the air cushion element preferably essentially completely bridges the predetermined or predeterminable distance between the support structures. In the inflated state, the air cushion element can also touch the lower support structure, in particular its upper side. More preferably, in the inflated state, the air cushion has an excess pressure compared to the ambient pressure, such that the air cushion presses the support structures apart. This is advantageous because the support structures thus form a stable unit, particularly in the case of a flexible connecting element.

[0044] Preferably, the air cushion element is arranged and configured such that there is no contact with the mast structure. In other words, the air cushion element is preferably arranged at a distance from the mast structure, both in the inflated and deflated state. This ensures the mobility of the support structures. Furthermore, the air cushion element is protected from damage caused by contact with the mast structure.

[0045] The air cushion element is preferably designed to be essentially airtight and sealed, eliminating the need for a continuous fluid introduction. This enables low-energy and / or low-emission operation of the device. Furthermore, it allows for a statically accurate load calculation.

[0046] The advertising carrier element can comprise a plurality of air cushion elements. Particularly advantageous, exemplary arrangements of air cushion elements are described with reference to the figures. Preferably, the plurality of air cushion elements together essentially completely surround the mast structure.

[0047] To fill and / or empty the air cushion element, the device can have an inflation device, for example a pump and / or a blower, in particular an electric air pump, for inflating the inflatable air cushion element. This can be mounted, for example, on the upper support structure. The inflation device can also be designed to selectively suck the fluid or air out of the air cushion element. The device can also have multiple inflation devices, which are preferably mounted on the upper support structure. In particular, if multiple air cushion elements are present, one inflation device can be provided per air cushion element.

[0048] Preferably, the advertising carrier element can further comprise an advertising carrier film, in particular a web banner and / or a canvas, which can be connected to the upper support structure and to the lower support structure. The advertising carrier film is preferably arranged radially outwardly of the air cushion element and / or is tensioned and / or tightened by the air cushion element in the inflated state.

[0049] Such an advertising element has the advantage of enabling a functional separation of the spans and / or tensions and the advertising space. This allows both components to be optimized and / or replaced easily and inexpensively. For example, the information and / or advertising on the advertising space can be easily replaced. Furthermore, this increases design freedom, especially in terms of material selection.

[0050] The advertising film can be made, in particular, of PVC. Preferably, the advertising film can be a "backlit banner," which can be backlit and is essentially airtight, thus ensuring particularly good visibility of the information.

[0051] An advantageous, non-destructive, reversible fastening of the advertising film can be implemented, for example, by means of a piping connection and / or a connection similar to a curtain rail or drapery rail. The advertising film can have a sewn-in and / or welded piping (core) at an upper and / or lower end, which can be inserted into a piping rail arranged on the upper and / or lower support structure, in particular on the radially outer edge thereof. Alternatively or additionally, the advertising film can have eyelets at an upper and / or lower end, which can be connected and / or lashed to the upper and / or lower support structure by means of a (wire) rope. For particularly simple installation, a combination of a piping connection at one end, in particular at the upper end, and eyelets at the other end, in particular at the lower end, is also possible.The advertising film can essentially completely surround the mast structure.

[0052] The device can preferably comprise a lighting device. In the inflated state of the air cushion element, a free space can be provided at least partially between the air cushion element and the advertising film, which can be illuminated by the lighting device in order to illuminate the advertising film from behind. The air cushion element can have a highly reflective surface, and the advertising film can be partially translucent. The lighting device can, for example, be mounted on the upper support structure and face the free space.

[0053] Alternatively or additionally, a lighting device can be provided inside the air cushion element, which illuminates the air cushion element from the inside. An at least partially transparent surface of the air cushion is advantageous. Alternatively or additionally, a lighting device can illuminate and / or illuminate the air cushion element or an advertising film from the outside.

[0054] A lighting device can make the information and / or advertising particularly easy to recognize and / or visible and / or conspicuous and simple to present.

[0055] Alternatively or additionally, the advertising film itself can have luminous elements.

[0056] The device may further comprise a control unit for controlling and / or regulating the device, in particular the lifting device. Preferably, the device further comprises a wind sensor that is communicatively connected, in particular wired or wirelessly, to the control unit. The control unit is preferably configured to automatically lower the support structures when the wind force detected by the wind sensor exceeds a predetermined and / or predeterminable wind force. This allows the device to limit the load on the mast structure, thus eliminating the need for additional reinforcement of the mast structure. In particular, compliance with the maximum permissible loads on the mast structure can be ensured. Redundant wind sensors can optionally be provided.

[0057] Such a control unit can ensure easy handling and / or increased operational reliability of the device. Automated lifting, for example, when wind speeds decrease, can ensure maximum advertising effectiveness. It is conceivable that weather forecasts, especially wind forecasts, and / or measured values ​​from nearby measuring stations could be evaluated and incorporated into the automated control system.

[0058] Furthermore, the device can have a height sensor that can determine the height and / or position of the support structure(s) and, preferably, communicate with the control unit. This allows the support structures to be shifted to assigned lowering levels, for example, at certain wind speeds, particularly by means of the control unit. Likewise, the support structures can be shifted to a higher lowering level, particularly by means of the control unit, when the wind speed falls below the corresponding level.

[0059] The inflation device of the device can further be configured to deflate the air cushion element and / or release the air from the inflated air cushion element. This can facilitate and / or accelerate the lowering of the upper support structure relative to the lower support structure and / or the compression of the air cushion element.

[0060] Alternatively or additionally, the device can have a compression device with a compression cable or a compression chain between the upper and lower support structures, wherein the compression device can actively reduce the distance between the support structures by pulling in and / or winding up the compression cable or the compression chain. This makes it possible to achieve particularly rapid compression and / or space-saving stowage of the support structures. The compression device can alternatively or additionally be designed to retract and / or roll up the flexible connecting element. This makes it possible to dispense with the provision of an additional compression cable and / or an additional compression chain. The drive of the compression device, for example comprising a cable winch and / or chain winch and / or drum for winding up / unwinding the compression cable orthe compression chain, can be mounted on the upper support structure, whereas the compression rope or the compression chain can be connected to the lower support structure.

[0061] Optionally, the device comprises an operating unit that is communicatively connected, in particular wired or wirelessly, to the control device and enables monitoring and / or control of the control device. In particular, the operating unit can enable manual raising or lowering of the support structure(s) and / or inflation or deflation of the air cushion element and / or switching of the lighting device.

[0062] Furthermore, the device may comprise a (parking) brake for at least temporarily locking the position of the frame structure(s).

[0063] The upper support structure and / or the lower support structure can have an inner support ring and an outer support ring, wherein the outer support ring is preferably mounted so as to be rotatable relative to the inner support ring, so that at least the advertising support element is rotatable relative to the mast structure.

[0064] Such a design represents a simple and / or lightweight and / or cost-effective construction that allows the advertising surface to be rotated. This allows the information and / or advertising to be aligned relative to the mast structure in a predefined and / or predetermined manner. Furthermore, the advertising surface can be rotated at least temporarily, thus achieving particularly eye-catching and effective advertising.

[0065] Preferably, a rotational position of the outer support ring can be at least temporarily determined and / or fixed. The device can have a rotational drive for rotating the outer support ring.

[0066] Preferably, the inner support ring is guided by the guide element, or the inner support ring has the coupling element. The inner and outer support rings can be connected in a manner that allows rotation relative to one another by means of struts and / or a framework structure.

[0067] When attached and / or mounted to a mast structure, the support structures are preferably closed and / or can be arranged completely around the mast structure. It is preferred that the support structures are each modular, for example, two-part, three-part, or four-part, so that they can be attached and / or mounted to a mast structure in a simple manner, especially retrofitted.

[0068] The device can have a display panel for displaying information, in particular advertising, in particular moving images. The display panel is preferably connected to the lower support structure in such a way that the display panel extends substantially diagonally upwards and radially outwards from a radial outer edge of the lower support structure. Such a display panel serves as an additional advertising panel. Furthermore, the display panel can be oriented diagonally downwards, thereby achieving better visibility from a lower position. The display panel also serves as additional protection for the advertising carrier element, for example from ropes and / or hooks of a construction crane mast structure. Furthermore, the display panel can serve as a safety cage and as a lateral privacy screen and / or cover when the support structures are retracted and / or compressed.

[0069] The display panel may, in particular, comprise one or more digital displays, such as LCDs. Preferably, one or more display panels are arranged substantially entirely around the mast structure.

[0070] The device may further comprise a pivoting device for pivoting, in particular moving and / or tilting the display panel(s), for example for adjusting the alignment angle in order to optimise visibility at a specific position around the mast structure.

[0071] The control unit is preferably configured to control the lifting device and / or the inflation device and / or the lighting device and / or the display panel and / or all or part of the other devices described above. Alternatively or additionally, the control unit can be configured to enable remote maintenance of the system and / or the input of digital information / advertising content, preferably in real time.

[0072] A further aspect of the invention relates to a mast construction comprising a device as described in the process.

[0073] The mast structure can be or comprise, for example, a mast or a tower. The mast structure can, in particular, be or comprise a substantially vertical, pillar-like structure. The mast structure preferably has a small footprint compared to its height. For example, the mast structure is or comprises: an antenna or transmission mast, a (power) transmission mast, a cable car support, a tower crane support structure, or a (support) pillar. The mast structure can have a foundation or be attached to or with it.

[0074] The mast structure may comprise a plurality of devices.

[0075] In the following, individual embodiments for achieving the object are described by way of example with reference to the figures. In some cases, the individual embodiments described have features that are not absolutely necessary to carry out the claimed subject matter, but which provide desired properties in certain applications. Thus, embodiments that do not have all the features of the embodiments described below are to be regarded as falling within the scope of the described technical teaching. Furthermore, to avoid unnecessary repetition, certain features are only mentioned in relation to individual embodiments described below. It is pointed out that the individual embodiments should therefore not only be considered in isolation, but also in conjunction with one another.Based on this overview, those skilled in the art will recognize that individual embodiments may also be modified by incorporating one or more features of other embodiments. It is noted that a systematic combination of the individual embodiments with one or more features described with reference to other embodiments may be desirable and useful and should therefore be considered and considered to be encompassed by the description.

[0083] Detailed description of the drawings

[0084] Figure 1 shows an exemplary mast construction 1 with an exemplary device 10 for attaching an advertising medium to the mast construction 1 in a side sectional view.

[0085] In the example shown, the mast structure 1 comprises a lattice mast of a construction crane, which is anchored in the ground by a foundation 2. The mast structure 1 is essentially vertically aligned.

[0086] The device 10 is arranged on the mast structure 1 and is located at an upper section 1a of the mast structure 1. In the state shown, the device 10 has an upper support structure 20 and a lower support structure 22, which are spaced apart by a predetermined axial distance A. The predetermined axial distance A is defined by the connecting elements 26, for example (wire) cables, which are tensioned between the support structures 20, 22. The connecting elements 26 are stretched and / or held under tension, for example, by the weight of the lower support structure 22.

[0087] In the example shown, the support structures 20, 22 are arranged substantially completely around and / or completely circumferentially around the mast structure 1. The upper and lower support structures 20, 22 each have a (wire) cable guide sleeve 30 as a coupling element 18, which is displaceably coupled to the guide elements 16. In the example shown, the guide elements 16 are guide (wire) cables stretched between the upper and lower guide fastenings 12, 14, which have a predetermined and / or predeterminable distance from the mast structure 1. Alternatively, the guide elements 16 can be fastened to the foundation 2 instead of the lower guide fastenings 14, which are arranged on a lower section 1b of the mast structure 1.

[0088] Preferably, the guide (wire) cables 16 and / or the guide fastenings 12, 14 are each additionally connected to the mast structure 1 via an anchor, whereby the guide (wire) cables 16 can be tensioned in such a way that they have high bending strength and thus high stability against lateral loads caused by wind. This allows lateral loads to be reliably compensated and / or absorbed, so that the support structures 20, 22 do not contact the mast structure 1 even in strong winds and simultaneously remain displaceable in the direction of the mast extension.

[0089] For moving the support structures 20, 22, in particular for raising or lowering the support structures 20, 22, the device 10 has a lifting device 24. The lifting device 24 shown in the example comprises a lifting cable 24, which is attached to an upper section 1a of the mast structure 1, and a drive, for example a lifting motor 24b, which is arranged on the upper support structure 20. The lifting motor 24b is configured to retract or release the lifting cable 24 in order to raise or lower the support structures 20, 22. For example, the lifting cable 24 can be wound onto a reel and / or drum or unwound from a reel and / or drum, with the lifting motor 24b driving the reel and / or drum.

[0090] In particular, the lifting device 24 is designed to displace the upper support structure 20 relative to the mast structure 1 essentially in the direction of mast extension and / or essentially vertically. However, by connecting the lower support structure 22 to the upper support structure 20 by the connecting elements 26, a displacement of the upper support structure 20 is transferred to the lower support structure 22, so that the latter is displaced essentially identically and / or concurrently.

[0091] In this example, the connecting elements 26 are flexible and / or designed as a (wire) cable. This enables force transmission to the lower support structure 22 only when the predetermined axial distance A is reached and / or the connecting elements 26 are stretched and / or tensioned. However, such a flexible connecting element 26 offers the advantage that the distance between the support structures 20, 22 can be smaller than the distance A, for example, when the lower support structure 22 rests against a stop and further lowering of the lower support structure 22 is prevented. Upon further lowering of the upper support structure 20, it approaches the lower support structure 22, whereby a compressed state of the support structures 20, 22 can be achieved.

[0092] The device 10 further comprises two air cushion elements 42, which are arranged between the support structures 20, 22. In Figure 1, the air cushion elements 42 are shown in an inflated state. Preferably, the air cushion elements 42 are coupled to the upper support structure 20 and bear against the lower support structure 22. In particular, the air cushion elements 42 are shaped and provided with an overpressure, for example, approximately 1.5 bar, such that they push the support structures 20, 22 apart and tension the connecting elements 26. This increases the stability of the overall structure.

[0093] The device 10 further comprises an advertising carrier film 44, which is arranged radially outwardly of the air cushion elements 42 and is stretched radially outwardly by the air cushion elements 42. As a result, the advertising surface 41 provided by the advertising carrier film 44 is essentially wrinkle-free and / or stretched to ensure a good presentation of information, in particular advertising, on the advertising surface 41.

[0094] For example, the advertising carrier film 44 can be fastened at its upper end to the upper support structure 20 by means of a piping connection and at its lower end to the lower support structure 22 by means of an eyelet (wire) rope connection.

[0095] The air cushion elements 42 are each illuminated by means of a lighting device 46 in order to achieve a particularly good presentation of the information and / or advertising.

[0096] One (left) air cushion element 42 has an interior illumination device 46, so that the air cushion element 42 is illuminated from within. Using a suitable, at least partially translucent material, at least in regions on the radially outwardly facing surface, the advertising film 44 can be illuminated by the illumination device 46.

[0097] The other (right) air cushion element 42 has an illumination device 46 between the air cushion element 42 and the mast structure 1, for illuminating the advertising carrier film 44 through the air cushion element 42. A material with high light transmission on the inside of the air cushion element 42 is advantageous to ensure sufficient light reaches the advertising carrier film 44.

[0098] The exemplary device 10 further comprises a control unit 32 for controlling and / or regulating and / or monitoring the lifting device 24 and / or the inflation device 38. The control unit 32 is preferably arranged on the upper support structure 20. Furthermore, all units and / or devices for controlling and / or monitoring and / or influencing the device are preferably arranged on the upper support structure 20, which in particular facilitates maintenance and commissioning. The device 10 can further comprise one or more wind sensors 34 for measuring the wind strength and / or wind speed. The upper support structure 20 preferably comprises at least one wind sensor 34 so that the wind speed at the height of the upper support structure 20 can be measured.Preferably, the signal from wind sensor 34 is transmitted to control unit 32 (wired or wirelessly), with control unit 32 preferably automatically initiating lowering of support structures 20, 22 when the measured wind force reaches and / or exceeds a predetermined maximum wind force. This reliably prevents overloading and / or damage to device 10 and / or mast structure 1.

[0099] The device 10 can have a height sensor and / or position sensor 36 that measures the height and / or position of the support structures 20, 22. The height and / or position thus measured can be taken into account by the control unit 32 for controlling the raising or lowering of the support structures 20, 22. For example, (pre-)determined lowering levels can be defined for associated wind strengths, which are activated in corresponding situations.

[0100] To maintain the inflated state of the air cushion elements 42, a controllable valve 39 can be arranged between the inflator 38 and the air cushion elements 42, which valve closes once the inflated state is reached. To deflate the air cushion elements 42, the valve 39 can be opened to allow the fluid to escape from the air cushion elements 42. The valve 39 and the inflator 38 can be controlled and / or monitored by the control unit 32.

[0101] A power supply for the control unit 32 and / or the lifting device 24 and / or the wind sensor 34 and / or the height sensor 36 and / or the inflation device 38 and / or the lighting devices 46 can be provided, for example, by means of a power cable connected to the local power supply. Alternatively, an energy storage device, in particular a battery and / or a rechargeable battery, and a generator unit, for example a solar panel and / or a wind turbine, can be provided so that the device can be operated essentially autonomously.

[0102] Figure 2 shows a view in the master extension direction (top view) of an exemplary mast construction 1 with exemplary guide fastenings 12 / 14.

[0103] The exemplary mast structure 1 is rectangular and has a guide fastening 12 / 14 at each corner for attaching a guide element 16. With such or a similar implementation, the support structures 20, 22 can be attached particularly securely to the mast structure 1. In particular, moments and transverse forces acting on the support structures 20, 22 can be particularly advantageously compensated and / or diverted via the multiple guide elements 16.

[0104] The guide fastenings 12 / 14 are preferably designed such that the guide elements 16 have an appropriate distal distance from the mast structure 1, so that contact with the mast structure 1 is prevented in the event of a slight displacement of the guide elements 16 and / or the support structures 20, 22. The longer the guide elements 16 and / or the greater the deflectability of the guide elements 16 orthogonal to the master extension direction, the greater the distance the guide elements 16 must be from the mast structure 1.

[0105] For a 3-cornered, 5-cornered or X-cornered mast construction 1, 3, 5 or X guide fastenings 12 / 14 are advantageous in order to achieve particularly good stability, especially against lateral wind loads.

[0106] Figure 3 shows exemplary designs of a support structure 20 / 22 with several advertising carrier elements 40.

[0107] Figure 3 a) shows a support structure 20 / 22 arranged around a mast structure 1, which has a substantially round support inner ring 23a and a square support outer ring 23b connected to the support inner ring 23a. The support outer ring 23b can be designed to be rotatable around the support inner ring 23 and / or around the mast structure 1 or to be substantially fixed relative thereto.

[0108] Preferably, the support inner ring 23a is mounted on the mast structure 1 via coupling elements 18 (not shown) with guide elements 16 (not shown).

[0109] In the exemplary embodiment of the device 10 shown, a plurality of air cushion elements 42 are arranged on the support structure 20 / 22. The air cushion elements 42 are essentially cuboid-shaped and are positioned such that the radial outer sides of the air cushion elements 42 essentially correspond to the radial outer edges 22a of the support structure 20 / 22. The air cushion elements 42 can be fluidically connected to one or more inflation devices 38 and can be inflated by them, preferably essentially simultaneously and / or similarly.

[0110] Furthermore, an advertising carrier film 44 is provided radially outwardly around the air cushion elements 42, the radially outwardly directed surface of which represents at least a portion of the advertising surface 41. Preferably, the advertising carrier film 44 is in contact with the air cushion elements 42 at least in some areas when inflated and is pressed radially outward by them, thereby tensioning them.

[0111] Figure 3 b) shows a support structure 20 / 22 as in Fig. 3 a), but with air cushion elements 42 having a different shape and position. In this exemplary embodiment, an air cushion element 42 is arranged at each outer corner of the support structure 20 / 22 such that the air cushion elements 42, when inflated, press the advertising film 44 distally outwards at the outer corners of the support structure 20 / 22, so that the advertising film 44 is essentially taut and / or wrinkle-free, even in the areas between the air cushion elements 42. The air cushions 42 can, for example, be cylindrical or elongated and / or oval or square in cross-section. A corresponding or similar embodiment has the advantage that the volume of the air cushion elements 42 is small and thus the time and energy required for inflation can be reduced. The weight of the device 10 can also be reduced as a result.

[0112] As shown, lighting devices 46 are arranged in the spaces between the air cushion elements 42 for illuminating the advertising film 44 from the radial inside and / or from behind. This allows advantageous illumination of the advertising support elements 40, in particular the advertising surface 41, to be achieved. Alternatively or additionally, the advertising film 44 can be illuminated from behind with a projector so that the projection is visible on the outer advertising surface 41. This allows changing information and / or moving images and / or films to be easily displayed on the advertising surface 41.

[0113] Figure 3 c) shows a support structure 20 / 22 with a round radial outer edge 22a. Such a design is simple in construction and particularly advantageous for continuous or intermittent rotation of the support outer ring 23b around the support inner ring 23a, since the air resistance during rotation is lower than with a square outer contour of the support structure 20 / 22. Furthermore, the wind attack surface or the wind load is generally lower with a round outer contour than with a square outer contour.

[0114] The device 10 of Figure 3 c) does not have an advertising foil 44. In this embodiment, the radially outwardly directed surface of the cushion element 42 or cushion elements 42 represents the advertising surface 41.

[0115] Figure 4 shows an exemplary device 10 attached to a mast structure 1 in different states.

[0116] Initially, the support structures 20, 22 are in a compressed state and / or in a resting state and / or in an initial position (a). The support structures 20, 22 are preferably located close to the foundation 2 and / or near the ground. In this state, the device 10, in particular the support structures 20, 22, has a small wind attack surface and generates a low wind load on the mast structure 1.

[0117] If, for example, the wind sensor 34 detects a wind force permissible for the operation of the device 10 over a certain period of time, the support structures 20, 22 can be raised (b)-c)). For example, the upper support structure 20 is raised by means of a lifting device 24 (not shown). When the maximum axial distance A between the support structures 20, 22 and the tensioned connecting elements 26 (b)) is reached, the lower support structure 22 is also raised (c)).

[0118] Once they have reached the predetermined operating height and / or operating position, the air cushion elements 42 are inflated via the inflation devices 38 (d). Preferably, the air cushion elements 42 are attached to the upper support structure 20 and, upon inflation, approach the lower support structure 22 and / or come into contact with the lower support structure 22.

[0119] During operation, the device 10 can now react quickly and easily to increasing wind loads at any time. For example, if a wind speed exceeding a predetermined maximum wind speed is detected, the support structures 20, 22 with inflated air cushion elements 42 can be automatically lowered to a lower height and / or position, so that the wind load on the mast structure 1 decreases to an acceptable level (e). This state can be maintained as long as the measured wind speed is permissible for this position.

[0120] If the measured wind strength allows the support structures 20, 22 to be raised, they can be raised again to a corresponding height and / or position (d)). However, if the wind strength increases or generally exceeds a maximum value for the operation of the device 10, the support structures 20, 22 can be brought into a compressed state (initial state) by releasing and / or emptying the air cushion elements 42 and lowering the upper support structure 20 (f)).

[0121] The release and / or emptying of the air cushion elements 42 at a low height and / or position is particularly advantageous since the wind speeds there are generally lower and a disadvantageous deformation of the air cushion elements 42, in particular towards the mast structure 1, during the release and / or emptying can be prevented, or at least reduced.

[0122] To prevent such deformation of the air cushion elements 42 or even contact with the mast structure 1, a compression device is advantageous, which is designed to actively bring the upper support structure 20 closer to the lower support structure 22 during the release and / or emptying of the air cushion elements 42. Preferably, the air cushion elements 42 are compressed, whereby the stability of the air cushion elements 42 is sufficiently maintained during the release and / or emptying, so that unfavorable deformation, in particular orthogonal to the mast structure 1 and in particular under the influence of lateral wind, can be prevented, or at least reduced.

[0123] However, the device 10 is also designed to release and / or empty the air cushion elements 42 at any height and / or position of the support structures 20, 22.

[0124] The support structures 20, 22 can be raised again at any time if the wind strength is appropriate (b)(c)).

[0125] Figure 5 shows another exemplary device 10 attached to a mast structure 1, wherein the device 10 has a display panel 50 for displaying information.

[0126] As shown, in this embodiment, the lifting cable 24a of the lifting device 24 is attached to an upper guide mount 12. This offers the advantage that no additional fastening device for the lifting device 24 needs to be mounted on the mast structure 1.

[0127] The guide elements 16 are also attached directly to the foundation 2, which means that no lower guide fastenings 14 have to be mounted on the mast structure 1.

[0128] In the example shown, the lower support structure 22 projects radially outward beyond the upper support structure 20 and / or the woven carrier film 44.

[0129] On the projecting region of the lower support structure 22, in particular on or near the radial outer edge 22a, display panels 50 are arranged, which, for example, have digital screens for additionally displaying information, in particular moving images.

[0130] In addition, the projecting area of ​​the lower support structure 22 offers the advantage that possible collisions with, for example, crane ropes (particularly when the device is arranged on a construction crane mast) are absorbed and damage to the upper support structure 20 and / or the weaving support elements 40 is prevented.

[0131] Furthermore, the projecting area can serve as a running surface, thereby facilitating installation and deinstallation of the advertising carrier elements 40, in particular the advertising carrier film 44, and / or maintenance of the device 10 and increasing safety for the maintenance personnel.

[0132] Figure 6 shows a device 10 with a tilted and / or pivoted display panel 50 for displaying information. Tilting the display surface 51 of the display panel 50 outward and downward is advantageous, as this allows for better visibility and / or recognizability of the information from a position below the display panel 50.

[0133] Preferably, the device 10 can have a pivoting device 52 to control the angle of inclination of the display panel 50. For example, in a higher position of the support structures 20, 22, the display panel 50 can be tilted more strongly toward the floor 4, and less strongly in a lower position. Preferably, the pivoting device 52 is connected to the control unit 32 and can be controlled by it, preferably automatically.

[0134] As shown, the device 10 comprises a connecting element 26, which is attached to the coupling elements 18 of the support structures 20, 22 to maintain a maximum distance A between the support structures 20, 22. This can be provided in addition to or alternatively to one or more connecting elements 26, which are attached directly to the support structures 20, 22.
