Description

[0001] The present invention relates to a large-format advertising board.

[0002] Large-format billboards are large-format advertising spaces often used in public spaces for outdoor advertising. They are used to place advertising messages in highly visible locations, such as streets, train stations, or shopping centers. In Germany, the most common size is 18 / 1 (18-sheet poster format), which corresponds to an area of ​​3.56 m × 2.52 m. Large-format billboards typically consist of a panel element made of metal, wood, or plastic with a smooth surface for poster placement.

[0003] The posters are typically attached using wet adhesive. This involves attaching paper sheets from a large-format poster to the panel element in numbered order using adhesive. Alternatively, self-adhesive posters or vinyl films can be used and applied to the panel element. The panel element, which serves as the base for the posters, is usually surrounded by front panels to create a more appealing overall appearance.

[0004] Another option for large-format advertising panels is the use of stretcher frame systems, in which a printed textile poster is clamped into a frame. These systems are currently used primarily in protected indoor areas, as they cannot reliably withstand weather-related influences, especially wind.

[0005] Against this background, the object of the present invention is to provide a large-format advertising board that can be used safely and permanently in unprotected outdoor areas with a textile poster.

[0006] The above-mentioned object is achieved according to the invention by a large-format advertising board for outdoor advertising comprising a textile poster, in particular with an area of ​​at least 8m 2, and front elements arranged circumferentially around the textile poster, wherein the textile poster has a circumferential piping, wherein at least four circumferentially arranged tensioning frame profiles are provided for fastening and tensioning the textile poster, wherein the tensioning frame profiles each have a guide chamber for receiving the piping, wherein the guide chambers have an opening in cross-section, wherein a piping flag attached to the textile poster or the textile poster is arranged in sections in the opening and wherein at least one securing element, preferably a plurality of circumferentially arranged securing elements, is arranged in the guide chambers for securing the piping, wherein the at least one securing element is designed and arranged such that it counteracts a movement of the piping in the direction of the opening.

[0007] The circumferentially arranged tensioning frame profiles each have a guide chamber into which a piping of a textile poster can be accommodated. The tensioning frame profiles form a piping rail for the textile poster with piping and preferably run over essentially the entire length of the front elements, with the corner areas left open. A piping is a reinforced edge on tarpaulins, banners or fabrics that is inserted into a matching piping rail to fasten the material taut and securely. The piping is either welded, sewn or otherwise attached directly to the edge of the material or, alternatively, connected to the material to be stretched via a piping flag. In the latter case, the piping flag establishes the connection between the piping and the material to be stretched.

[0008] Attaching the textile poster to the large-format advertising board using piping allows for quick and easy motif changes, as the piping of the old textile poster simply needs to be pulled out of the guide chambers of the stretcher frame profiles and the piping of the new textile poster needs to be inserted into the guide chambers of the stretcher frame profiles. Furthermore, this type of attachment represents a durable and weatherproof solution for outdoor use.

[0009] According to the invention, not only the piping but also the at least one securing element is arranged in the guide chambers of the clamping frame profiles. The at least one securing element is designed and arranged in the guide chamber in such a way that it counteracts any movement of the piping toward the opening of the guide chamber and increases the hold of the piping in the intended position. The securing element thus reduces the risk of the piping slipping out of the guide chambers of the clamping frame profiles, particularly in adverse weather conditions such as strong winds.

[0010] Various embodiments of the large-format advertising board are described below. Each of the individual embodiments applies independently of the large-format advertising board. Furthermore, the individual embodiments can be combined with one another as desired.

[0011] In an advantageous embodiment of the large-format advertising board for outdoor advertising, the at least one securing element is more dimensionally stable than the piping. Preferably, the at least one securing element has an E-module of at least 5 GPa and the piping a E-module of at most 3.5 GPa. Preferably, the at least one securing element and the piping form a press fit in the guide chambers. Advantageously, the piping can be pushed first and then the at least one securing element through the opening in the clamping frame profile into the guide chamber. When the at least one securing element is pushed into the guide chamber, the piping is pressed together by the pressure of the securing element, creating a press fit between the clamping frame profile, the piping and securing element. The press fit has the advantageous effect of ensuring that the piping sits particularly firmly in the guide chambers.This is especially important in windy weather conditions.

[0012] Advantageously, the piping is made of a rubber material. The piping or the rubber material of the piping preferably has a maximum modulus of elasticity of 3.5 GPa. A rubber material exhibits a certain degree of elasticity and facilitates the formation of a press fit between the clamping frame profile and the securing element. Furthermore, a rubber material enables a good coefficient of friction between the piping and the clamping frame profile, which in turn has a positive effect on the secure hold of the piping in the guide chambers.

[0013] Advantageously, the at least one securing element is made of a plastic or a metal. Such materials offer sufficient strength to allow the securing element to be inserted into the guide chamber in which the piping is already arranged. The materials for the piping and the at least one securing element should, in particular, be selected so that the securing element can compress the piping when pressure is applied to it. Preferably, the at least one securing element has a modulus of elasticity of at least 5 GPa and / or a flexural strength of at least 120 MPa.

[0014] Particularly preferably, the at least one securing element is designed as a particularly substantially rectangular plate with a thickness of 0.2 to 1.5 cm, in particular from 0.4 to 1.2 cm, particularly preferably from 0.6 to 1.0 cm and further preferably from 0.7 cm. In a particularly preferred embodiment of the invention, the securing element designed as a rectangular plate has a height of 1.0 to 2.0 cm, in particular from 1.2 to 1.8 cm and particularly preferably from 1.5 cm and a width of at least 10 cm, in particular of at least 12 cm and particularly preferably of at least 15 cm. A correspondingly designed securing element is particularly inexpensive and simple to manufacture and can be easily inserted into the guide chambers of the clamping frame profiles.

[0015] The plate-shaped securing element preferably has a shorter length than the associated clamping frame profile, so that a plurality of plate-shaped securing elements can be introduced into the guide chambers of the clamping frame profiles at a distance from one another.

[0016] In an advantageous embodiment of the invention, the piping is 1 to 5 cm thick, preferably 2 to 4 cm, and particularly preferably 3 cm thick. A correspondingly thick piping can be easily compressed and form a press fit with the securing element in the guide chamber.

[0017] In a particularly preferred embodiment of a large-format advertising panel according to the invention for outdoor advertising, the opening of the guide chambers is designed for the insertion of the piping and the at least one securing element.

[0018] With the traditional method of mounting a textile poster in a piping rail, the piping is inserted into the guide chambers at the side ends of the piping rail. The piping itself cannot pass through the opening in the cross-section of the tensioning frame profiles. With such a design, mounting a textile poster on a large-format billboard has proven to be unfavorable, as the tensioning frame profiles must be arranged all the way around the textile poster to ensure the textile poster is securely held on the billboard, even in adverse weather conditions. In this case, the tensioning frame profiles would have to be mounted on the billboard together with the textile poster.

[0019] In the described preferred embodiment of the invention, the piping can be inserted through the opening in the cross-section of the stretcher frame profiles. Inserting the piping over the side ends of the stretcher frame profiles is no longer necessary. This facilitates the installation of textile posters on the large-format advertising board.

[0020] The same applies to the at least one securing element, which is inserted into the guide chambers, preferably after insertion of the piping.

[0021] Preferably, the at least one securing element rests against an inner side of the guide chambers associated with the circumferential front elements. This arrangement has proven particularly advantageous for assembly, since the inner side of the guide chambers associated with the circumferential front elements is most easily accessible when the textile poster is mounted.

[0022] In one embodiment of the large-format billboard for outdoor advertising, the piping is attached to one side of the textile poster. In this case, the piping can come into contact with the inner sides of the guide chambers. This is particularly advantageous if the piping has a higher coefficient of friction than the textile poster in the guide chamber due to the choice of material, since a higher coefficient of friction fixes the piping more firmly in the guide chambers. In this case, it is particularly advantageous if the at least one securing element is arranged in the guide chambers on the side of the textile poster facing away from the piping so that the piping can come into contact with the inner sides of the guide chambers.

[0023] Advantageously, the at least one securing element projects beyond the piping in the cross-section of the clamping frame profiles, as viewed toward the opening. This simplifies the removal of the at least one securing element from the guide chamber when changing the motif.

[0024] Advantageously, the tensioning frame profiles have a barb-shaped section on their guide chambers, particularly in the area of ​​the opening, for securing a welt in the guide chambers. The barb-shaped section is preferably formed on an inner side of the guide chambers facing away from the circumferential front elements, i.e., on the inner side of the tensioning frame profile facing the textile poster, since it particularly reliably prevents the welt from slipping out of the guide chambers there. The barb-shaped section can, for example, be realized by a substantially rectangular section that is adapted to the outer contour of the welt.

[0025] In one embodiment of the invention, the guide chambers are open at the front when viewed from the front of the large-format advertising board. In this case, the piping can be inserted into the guide chambers from the front. With this preferred embodiment of the invention, the tension frame profiles can be attached particularly conveniently to the large-format advertising board without covering much of the panel element. Furthermore, installing the piping into the guide chambers from the front is significantly more ergonomic than if the piping had to be inserted into the guide chambers from below or above on the upper or lower tension frame profile.

[0026] In one embodiment of the large-format outdoor advertising panel according to the invention, the guide chambers of the tensioning frame profiles are essentially rectangular in cross-section. Rectangular guide chambers, in particular, allow for the accommodation of rectangular piping. This design has proven particularly useful for ensuring the secure hold of the textile poster even under challenging weather conditions.

[0027] Advantageously, the guide chambers of the clamping frame profiles have inward-facing projections on their inner sides, in particular with a partially circular cross-section. The projections preferably have a height of 0.1 to 0.4 mm, more preferably 0.2 to 0.3 mm, and in particular 0.25 mm. These projections increase the friction between the piping and the clamping frame profile or between the securing element and the clamping frame profile in the guide chamber, so that the piping or the securing element is held particularly firmly in the guide chamber. When using an elastic piping and corresponding geometric proportions, the projections can press into the material of the piping and hold it firmly in the guide chambers of the clamping frame profiles, thus reducing the risk of the piping slipping out of the guide chambers, even in demanding weather conditions.

[0028] It has proven particularly advantageous if the projections are arranged on opposite sides of the guide chambers, since in this case the friction is increased from several sides.

[0029] In one embodiment of the large-format billboard for outdoor advertising, at least 8, in particular at least 12, preferably at least 16, and particularly preferably at least 20 securing elements are arranged circumferentially in the guide chambers. Preferably, at least two securing elements are arranged in each corner region of the large-format billboard. The securing elements are preferably arranged at a substantially identical distance from one another (with the exception of the two securing elements arranged in the corner regions). A correspondingly large number of securing elements allows for a particularly strong and circumferentially uniform fixation of the piping of the textile poster in the guide chambers.

[0030] The clamping frame profiles are preferably made of extruded profiles, in particular extruded aluminum profiles. Extruded profiles, and in particular extruded aluminum profiles, offer a cost-effective way to create lightweight and dimensionally stable clamping frame profiles. The extruded aluminum profiles can be made, for example, of an AlMgSi alloy.

[0031] In a particularly preferred embodiment of the large-format advertising board, a board element, in particular with an area of ​​at least 8 m 2, for attaching a poster or similar using wet gluing, arranged behind the textile poster. The panel element also allows for traditional poster attachment, for example using wet gluing. In addition to this traditional method of attaching a poster, a textile poster can be stretched and attached to the large format advertising panel in such a way that it can be safely displayed outdoors as well. This offers the advantage that mixed display is possible, i.e., on the one hand, display with a poster attached to the panel element in the traditional way and, on the other hand, display with a stretched textile poster outdoors.

[0032] In a particularly advantageous embodiment of the invention, backlighting is provided to illuminate the textile poster from behind. Backlighting enables a particularly appealing appearance, especially in the dark.

[0033] Further features and advantages of the large-format advertising board will become apparent from the following description of exemplary embodiments, with reference to the attached drawing.

[0034] Further features and advantages of the large-format advertising board will become apparent from the following description of exemplary embodiments, with reference to the attached drawing.

[0036] Fig. 1A shows a first embodiment of a large-format billboard for outdoor advertising according to the invention in a perspective exploded view.

[0037] The large-format advertising board comprises a panel element 2 for attaching a poster or the like (not shown here), in particular by means of wet bonding, and front elements 4 arranged circumferentially around the panel element. In addition, the large-format advertising board has four circumferentially arranged tensioning frame profiles 6 for fastening and tensioning a textile poster 8 (not shown here), wherein the tensioning frame profiles 6 each have a guide chamber 26 for receiving a piping 12. Furthermore, a tensioning frame 14 is provided, which can be fastened to the panel element 2 by means of holding brackets 16. The tensioning frame profiles 6 can be mounted on the panel element 2 via the tensioning frame 14. The tensioning frame 14 is formed by four interconnected rectangular tubes 18. The tensioning frame profiles 6 and the rectangular tubes 18 are made of extruded profiles, in particular of extruded aluminum profiles made of an AlMgSi alloy.

[0038] According to the invention, securing elements 32 are provided for securing the piping 12 of the textile poster 8 (not shown here) in the guide chamber 26 of the stretcher frame profiles 6. The securing elements 32 are plate-shaped and can be inserted into the guide chamber 26 in addition to the piping 12 of the textile poster 8 (not shown here). The securing elements 32 extend in sections along the stretcher frame profiles 6 and do not run over the entire length of the stretcher frame profiles 6. Two securing elements 32 are arranged in each corner area of ​​the large-format advertising panel. The securing elements 32 are arranged, preferably uniformly (with the exception of the securing elements 32 arranged in the corner areas), circumferentially at a distance from one another in the guide chambers 26.

[0039] Another advantage of the Fig. The embodiment shown in Figure 1A relates to the possibility of retrofitting a classic large-format advertising board that is only suitable for attaching a poster or the like, for example, using wet bonding. This can be retrofitted with little effort to enable the attachment and tensioning of a textile poster 8 as an alternative to attaching a poster to the board element 2. Specifically, for the retrofit, only the tensioning frame 14 needs to be screwed onto the board element 2 using retaining brackets 16, and the tensioning frame profiles 6 need to be attached to the tensioning frame 14 all the way around, for example using screws.

[0040] Fig. 1B shows the large-format advertising board from Fig. 1A in perspective view.

[0041] In Fig. 1C is the large-format advertising board made of Fig. 1A with a textile poster 8 in perspective view. The textile poster 8 has an area of ​​at least 8m2 , wherein the textile poster 8 in particular has a motif in a size of 3.56 m × 2.52 m.

[0042] Fig. 1D shows the large-format billboard from Fig. 1C in cross-section, wherein the circumferential clamping frame profiles 6, the front elements 4, the clamping frame 14 and other circumferential elements are essentially identical in cross-section. It can be seen that the clamping frame 14 is formed by four interconnected rectangular tubes 18, to which the clamping frame profiles 6 are fastened by means of screws 20. The clamping frame profiles 6 have a screw channel 21 for this purpose. The holding angles 16, via which the clamping frame 14 is fastened to the panel element 2, are mounted on the panel element 2 with screws 22. The circumferential front elements 4 are attached to the panel element 2 via adapter profiles 24.

[0043] The tensioning frame profiles 6 each have a guide chamber 26. The guide chamber 26 has a substantially rectangular cross-section. The textile poster 8 has a circumferential piping 12 arranged in the guide chamber 26 of the tensioning frame profile 6. The piping 12 is attached to the back of the textile poster 8 and also has a substantially rectangular cross-section.

[0044] The guide chamber 26 of the stretcher frame profiles 6 has an opening 28 in cross-section through which the piping 12 of the textile poster 8 can be inserted. The guide chamber 26 is open at the front, so that the opening 28 extends along the front side of the stretcher frame profiles 6 facing the textile poster 8. The opening 28 of the guide chamber 26 serves not only as a breakthrough for the textile poster 8 but also as an opening for inserting the piping 12 from the front. Accordingly, the piping 12 does not have to be pushed into the guide chambers 26 at the lateral ends of the stretcher frame profiles 6, but can be inserted into the guide chambers 26 from the front. This facilitates the mounting of the textile poster 8 on the large-format advertising board.

[0045] The tensioning frame profiles 6 have, in cross-section, a barb-shaped section 30 on their guide chambers 26 in the region of the opening 28 for securing the piping 12 in the guide chambers 26. The barb-shaped section 30 is formed on an inner side of the guide chambers 26 facing away from the circumferential front elements 4. The barb-shaped section 30 is formed by a substantially rectangular section that secures the substantially rectangular piping 12 of the stretched textile poster 8 in the guide chamber 26, particularly in difficult weather conditions, for example, strong winds.

[0046] The securing element 32 is arranged in the guide chamber 26 next to the piping 12. The securing element 32 serves to secure the piping 12 in the guide chamber 26. The securing element 32 lies against an inner side of the guide chamber 26 associated with the circumferential front elements 4 and prevents the piping 12 from moving in the Fig. 1D shown cross section upwards towards opening 28.

[0047] The piping 12 is made of a rubber material, while the securing element 32 is made of a plastic or metal. The securing element 32 is more dimensionally stable than the piping 12, so that the piping 12 can be compressed when the securing element 32 is inserted into the guide chamber 26, and in the final position, a press fit is formed between the securing element 32, the piping 12, and the clamping frame profile 6. The securing element 32 has a modulus of elasticity of at least 5 GPa and a flexural strength of at least 120 MPa, while the piping 12 has a maximum modulus of elasticity of 3.5 GPa.

[0048] The securing element 32 is designed as a substantially rectangular plate with a thickness of approximately 0.7 cm, a height of approximately 1.5 cm, and a width of at least 10 cm. The piping 12 has a thickness of approximately 3 cm. The opening 28 of the clamping frame profile 6 is designed to be large enough that the piping 12 and subsequently the securing element 32 can be inserted into the guide chamber 26. The securing element 32 is arranged in the guide chamber 26 on the side of the textile poster 8 facing away from the piping 12, so that the securing element 32 can be introduced into the guide chamber 26 after the piping 12 has been inserted, without the textile poster 8 covering the opening 28.

[0049] In the cross-section of the clamping frame profiles 6, the securing element 32 projects beyond the piping 12 as seen towards the opening 28. This simplifies the removal of the securing element 32 from the guide chamber 26 when changing the motif.

[0050] In the Fig. 2A-D shows a second embodiment of a large-format advertising panel according to the invention in a perspective view. In contrast to the Fig. 1A-1D, no clamping frame is provided for fastening the clamping frame profiles. Fig. In the large-format advertising board shown in Figures 2A-D, the tension frame profiles 6' are attached directly to the surrounding front elements 4.

[0051] The fastening of the clamping frame profiles 6' to the surrounding front elements 4 is particularly in the Fig. 2D. It can be seen that the clamping frame profile 6' is screwed to the associated front element 4 by means of a screw 20.

[0052] This embodiment also allows for the easy retrofitting of a traditional large-format advertising board, which is only suitable for attaching a poster to the panel element 2', to a large-format advertising board to which a textile poster can also be attached and stretched. For the retrofit, only four clamping frame profiles 6' need to be screwed circumferentially to the inside of the front elements 4. Alternatively, the clamping frame profiles 6' can also be glued to the front elements 4.

[0053] In the Fig. 3A-3C is the 6' frame profile of the large format advertising board made of Fig. 2A in cross-section in a detailed view during the insertion of the piping 12 through the opening 28' into the guide chamber 26' ( Fig. 3A), during the insertion of the safety element 32 through the opening 28' into the guide chamber 26' ( Fig. 3B) and the assembled final state ( Fig. 3C). It can be seen that first the piping 12 is pushed into the guide chamber 26' from the front and hooked behind the hook-shaped section 30' of the clamping frame profile 6'. Subsequently, the securing element 32 can also be pushed through the opening 28', so that the piping 12 is fixed in the guide chamber 26' of the clamping frame profile 6'. In the assembled state, the piping 12 rests against the inside of the guide chamber 26' facing away from the front elements 4, while the securing element 32 rests against the inside of the guide chamber 26' facing the front elements 4.

[0054] The detailed view shows that the guide chamber 26' of the clamping frame profile 6' has inwardly directed projections 34' on its inner sides, with the projections 34' being arranged on opposite sides of the guide chamber 26'. The projections 34' have a partially circular cross-section with a height of 0.25 mm, although other cross-sections are also conceivable. The projections 34' increase the friction between the piping 12 and the clamping frame profile 6' or between the securing element 32 and the clamping frame profile 6' in the guide chamber 26', so that the piping 12 is held particularly firmly in the guide chamber 26'.

[0055] The piping 12 is formed from an elastic material, allowing the projections 34' to press into the material of the piping 12 and hold it firmly in the guide chamber 26' of the tensioning frame profile 6', thus reducing the risk of the piping 12 slipping out of the guide chamber 26', even under challenging weather conditions. Since the projections 34' are arranged on opposite sides of the guide chamber 26', friction is increased from multiple sides, which has a particularly positive effect on the fixation of the piping 12 in the guide chamber 26'.

[0056] Fig. 4 shows a detailed view of the large-format advertising board from Fig. 2C during the assembly of the textile poster 8 in a perspective view. It can be seen how the piping 12 attached to the back of the textile poster 8 is pushed into the guide chamber 26' of the stretcher frame profile 6' from the front. After the piping 12 has been inserted into the guide chamber 26', a plurality of circumferentially arranged securing elements 32 can be pushed through the opening 28' of the stretcher frame profile 6' into the guide chamber 26' of the stretcher frame profile 6', so that the piping 12 of the textile poster 8 is held particularly firmly in the guide chamber 26'. The assembly of the securing elements 32 is indicated by a dashed securing element 32 and an arrow.

[0057] Preferably, at least 8, in particular at least 12, more preferably at least 16, and particularly preferably at least 20 securing elements 32 are arranged circumferentially in the guide chambers 26' of the clamping frame profiles 6' at a distance from one another. It can be seen that the securing elements 32 are designed as small plates and extend only in sections along the clamping frame profiles 6' and do not run over the entire length of the clamping frame profiles 6'.

[0058] In Fig. Figure 5 shows a third embodiment of a large-format advertising panel according to the invention in cross-section. Like the second embodiment, the third embodiment shows a variant in which the circumferential clamping frame profiles 6" are attached to the circumferential front elements 4". The fixing of the circumferentially arranged clamping frame profiles 6" to the circumferentially arranged front elements 4" can be achieved via an adhesive connection, a screw connection, or the like.

[0059] Fig. 6 shows the clamping frame profile 6' from Fig. 3A in cross-section in a detailed view with a blind piping 36, which can be arranged in the guide chamber 26' of the tension frame profile 6' as an alternative to the piping 12 of the textile poster 8. The blind piping 36 can be used when the large-format advertising board is conventionally managed with a poster on the panel element 2 and no textile poster 8 is mounted on the large-format advertising board.

[0060] The blind piping 36 is inserted, as indicated by the dashed line, from the front through the opening 28' of the clamping frame profile 6' into the guide chamber 26' of the clamping frame profile 6'. The blind piping 36 has a stop 38 which, when mounted, rests against a section of the clamping frame profile 6' and prevents the blind piping 36 from slipping too far into the guide chamber 26' and from being easily pulled out of the guide chamber 26'.

[0061] The blind piping 36 is designed to close the opening 28' of the guide chamber 26'. This prevents dirt such as glue and dust from penetrating the guide chambers 26' of the clamping frame profiles 6'.

[0062] The blind piping 36 is made of a rubber material and exhibits a certain degree of elasticity. The rubber material of the blind piping has a maximum modulus of elasticity of 3.5 GPa. This easily enables the formation of a press fit by compressing the blind piping 36 when inserted through the opening 28' into the guide chamber 26'. Furthermore, the rubber material enables a good coefficient of friction between the blind piping 36 and the clamping frame profile 6', which in turn has a positive effect on the secure hold of the blind piping 36 in the guide chamber 6'. The blind piping 36 advantageously has essentially the same length as the corresponding clamping frame profile 6', so that the clamping frame profile 6' is closed from the front over its entire length.
