Description

The present invention relates to a large-area advertising panel for exterior advertising comprising a panel element, in particular with an area of at least 8 m 2, for attaching a poster or the like, in particular by means of wet adhesive bonding, and front elements arranged circumferentially around the panel element.Large-area advertising panels are large-format advertising areas which are frequently used in public spaces for exterior advertising. They serve to place advertising messages in a well visible manner at high-frequency locations, such as on roads, station stations or shopping centers. In Germany, the most common size is 18 / 1 (18 sheets of placard format), which corresponds to an area of 3.56 m×2.52 m. Large-area advertising panels usually comprise a panel element made of metal, wood or plastic, which has a smooth surface for placement.The plaques are generally applied by wet bonding. Here, paper sheets of a large-area plate are attached to the panel member in numbered order by means of pasters. Alternatively, self-adhesive placards or vinyl films may be used which are applied to the sheet member. The panel element, which serves as a basis for the placement of the poster, is usually bordered by front elements in order to achieve a more appealing overall optical image.A further possibility for a large-area advertising board is the use of tentering frame systems in which a printed textile pallet is clamped into a frame. Corresponding known systems are currently predominantly used in the protected interior region, since the known systems cannot reliably withstand the weather-related influences, in particular wind.Against this background, the object of the present invention is to specify a large-area advertising board which can be used safely and permanently with a textile placard in the unprotected outer region. In addition, it is desirable if mixed management, i.e. firstly management with a poster attached to the panel element, for example by means of wet adhesive bonding, and secondly management with a tensioned textile poster is possible.The aforementioned object is achieved according to the invention by a large-area advertising panel for exterior advertising comprising a panel element, in particular with an area of at least 8 m 2, for attaching a poster or the like by means of wet adhesive bonding and front elements arranged circumferentially around the panel element, in which at least four circumferentially arranged tentering frame profiles are provided for fastening and tensioning a textile poster, wherein the tentering frame profiles each have a guide chamber for receiving a piping.The panel element also makes it possible to mount a poster conventionally, for example by means of wet bonding. In addition to this classic attachment possibility for a poster, a textile poster can be tensioned and fastened on the large-area advertising board in such a way that safe management is possible even in the outer area. This offers the advantage that a mixed management, i.e. firstly a management with a poster mounted on the panel element in a classic manner and secondly a management with a tensioned textile poster in the outer region is possible.The circumferentially arranged tentering frame profiles each have a guide chamber into which a piping of a textile board can be accommodated. The tentering frame profiles form a piping rail for the textile board with piping and preferably run over substantially the entire length of the front elements, wherein the corner regions are cut out. A piping is a reinforced edge on tarpaulins, banners or fabrics which is inserted into a matching piping rail to tightly and securely attach the material. The piping is either welded, sewn or otherwise attached directly to the edge of the material or alternatively connected to the material to be clamped by a piping tag. In the latter case, the piping tag establishes the connection between piping and the material to be clamped.The fastening of the textile plate to the large-area advertising board by means of a piping allows a fast and uncomplicated motif change, since only the piping of the old textile plate has to be pulled out of the guide chambers of the tentering frame profiles and the piping of the new textile plate has to be inserted into the guide chambers of the tentering frame profiles. In addition, a corresponding fastening represents a long-lived and weather-resistant solution for the exterior.A further advantage relates to the possibility of mixing management. The tentering frame profiles can be fastened to the edge of the large-area advertising panel in such a way that they only slightly cover the panel element, so that the large-area advertising panel can still be used for placards fitted classically on the panel element even with mounted tentering frame profiles.Various embodiments of the large area advertising panel are described below, wherein the individual embodiments apply in each case independently of one another to the large area advertising panel. Moreover, the individual embodiments can be combined with one another as desired.In a preferred embodiment of the large-area advertising panel for exterior advertising, the circumferentially arranged clamping frame profiles are fastened to the front elements. If the front elements are sufficiently dimensionally stable, have a flat section of sufficient size for attaching the clamping frame profiles and have a suitable format, the clamping frame profiles can be fastened circumferentially to the front elements. In a corresponding embodiment of the invention, existing large-area advertising panels, which up to now could only be managed in a classic manner by attaching a poster to the panel element, can be retrofitted in a particularly low-complexity manner.Advantageously, the clamping frame profiles are fastened to the front elements, in particular to their inner sides, by a screw connection or an adhesive connection. This enables a particularly low-complexity retrofitting of existing large-area advertising panels.As an alternative to the fastening to the front elements, the circumferentially arranged clamping frame profiles can be fastened to a clamping frame which is mounted on the panel element via retaining brackets. If the peripheral front elements do not have sufficient dimensional stability, do not have a section on which there is sufficient area for attaching the tenter profiles or do not have the appropriate format, the tenter profiles can be fastened via a tenter frame. This can in turn be fastened via circumferentially spaced holding brackets on the panel element serving as the adhesive surface. For example, at least 18, preferably at least 22, and particularly preferably at least 28 holding brackets can be used so that the clamping frame is mounted fixedly and securely on the panel element.When retrofitting an old large-area advertising board, this fastening method allows some flexibility with regard to the dimensions, since the dimensions for the textile pallet are not exactly predefined by the dimensions of the front elements. The outer circumference of the tentering frame can be designed, for example, to be somewhat smaller than the outer circumference of the panel element or than the inner circumference of the front elements and can be explicitly adapted to the desired format of the textile plate. For applying a textile plate of the classic size, a width, measured from the outer surfaces of the tentering frame, of 3568 mm and a height, measured from the outer surfaces of the tentering frame, of 2548 mm have proven to be expedient.In an advantageous embodiment of the invention, the clamping frame comprises four rectangular tubes which are connected to one another and which can be welded to one another, for example. The use of rectangular tubes enables the realization of a lightweight, but dimensionally stable tenter frame in a cost-effective manner. For the production of the tenter frame, it is possible to use, for example, rectangular tubes having a width of 30 mm, a height of 20 mm and a thickness of 2 mm.In one embodiment of the invention, the holding brackets are fastened to the panel element by means of screws. This allows easy retrofitting of old large-area advertising panels.The clamping frame profiles are preferably formed from extruded profiles, in particular from extruded aluminum profiles. Extruded profiles and in particular extruded aluminum profiles offer a cost-effective possibility of realizing light and dimensionally stable tenter frame profiles. The extruded aluminum profiles can be formed, for example, from an AlMgSi alloy. The same applies to the clamping frame formed from rectangular tubes.In one embodiment of the large-area advertising panel according to the invention for exterior advertising, the guide chambers of the tentering frame profiles are of substantially rectangular configuration in cross section. Rectangular guide chambers make it possible in particular to accommodate rectangular pipings. A corresponding configuration has proven to be particularly expedient in order to ensure a secure hold of the textile plate even under demanding weather conditions.Advantageously, the guide chambers of the clamping frame profiles have projections on their inner sides which are directed inwards, in particular partially circular in cross section. The projections preferably have a height of 0.1 to 0.4 mm, more preferably of 0.2 to 0.3 mm and in particular of 0.25 mm. These projections increase the friction between the piping and the clamping frame profile in the guide chamber, so that a piping is held particularly firmly in the guide chamber. When using an elastic piping and corresponding geometric conditions, the projections can press into the material of the piping and hold it firmly in the guide chambers of the tenter frame profiles, so that the risk of the piping slipping out of the guide chambers is reduced even under demanding weather conditions.It has proven to be particularly advantageous if the projections are arranged on opposite sides of the guide chambers, since in this case the friction is increased from a plurality of sides.In a particularly preferred embodiment of a large-area advertising panel according to the invention for exterior advertising, the guide chambers of the tentering frame profiles have an opening in cross section, wherein a piping tag attached to the textile board or the textile board is arranged in sections in the opening and wherein the opening of the guide chambers is designed for inserting a piping.In a classic fastening of a textile plate in a piping rail, the piping is introduced into the guide chambers at the lateral ends of the piping rail. The piping itself cannot be passed through the opening present in the cross section of the tenter profiles. In a corresponding configuration of the piping rail, the mounting of a textile plate on a large-area advertising panel has proven to be disadvantageous, since the tentering frame profiles have to be arranged circumferentially around the textile plate in order to ensure a secure hold of the textile plate on the large-area advertising panel even under difficult weather conditions. In this case, the tentering frame profiles would have to be mounted on the large-area advertising board together with the textile pallet.In the described preferred embodiment of the invention, the piping can be inserted through the opening provided in the cross section of the tenter profiles. It is no longer necessary to introduce the piping over the side ends of the tenter profiles. This facilitates the mounting of textile plaques on the large-area advertising board.Advantageously, the clamping frame profiles have a barb-shaped section on their guide chambers, in particular in the region of the opening, for retaining a piping in the guide chambers. The barb-shaped section is preferably formed, as seen in cross section, on an inner side of the guide chambers facing away from the encircling front elements, i.e. on the inner side of the tentering frame profile facing the textile post, since it particularly reliably prevents the piping from slipping out of the guide chambers there. The barb-shaped section can be realized, for example, by a section which is substantially rectangular and is adapted to the outer contour of the piping.In one embodiment of the invention, viewed in a front view of the large-area advertising panel, the guide chambers are formed so as to be open toward the front. In this case, the piping can be introduced into the guide chambers from the front. In this preferred embodiment of the invention, the tentering frame profiles can be mounted particularly favorably on the large-area advertising panel without covering a large area of the panel element. Moreover, the mounting of the piping into the guide chambers from the front is clearly more ergonomic than if the piping on the upper or lower tenter frame profile has to be inserted into the guide chambers from below or from above.A textile pallet with a circumferential piping is preferably fastened to the tentering frame profiles, wherein the piping is arranged in the guide chambers. A circumferential piping allows a particularly secure hold of the textile plate on the large-area advertising board.In a particularly advantageous embodiment of a large-area advertising panel according to the invention for exterior advertising, at least one securing element, preferably a plurality of circumferentially arranged securing elements, is arranged for securing the piping in the guide chambers. The securing element can be introduced into the guide chambers in addition to the piping and thus fix the piping by forming a press fit. This is possible in particular if the at least one securing element is designed to be more dimensionally stable than the piping. This enables the formation of a press fit between the clamping frame profile, the piping and the securing element in a particularly simple manner. Advantageously, the piping element can be inserted first and then the securing element can be inserted through the opening of the clamping frame profile into the guide chamber. Corresponding securing elements simultaneously make possible an easy accommodation and a particularly firm seating of the piping in the guide chambers. The latter is important in particular in windy weather conditions.Preferably, the at least one securing element abuts an inner side of the guide chambers assigned to the encircling front elements. A corresponding arrangement has proven to be particularly advantageous for the assembly, since the inner side of the guide chambers assigned to the encircling front elements is clearly more accessible when the textile pallet is assembled.Advantageously, the at least one securing element is formed from a plastic or a metal. Corresponding materials offer sufficient strength to allow a securing element to be inserted into a guide chamber in which a piping element is already arranged. The at least one securing element preferably has a modulus of elasticity of at least 5 GPa and / or a flexural strength of at least 120 MPa.Advantageously, as an alternative to the piping of the textile plate, a blind piping is arranged in the guide chambers. The blind wedge can be used if the large-area advertising board is customarily managed with a poster on the panel element and no textile poster is mounted on the large-area advertising board. Preferably, the blind cedar closes the opening of the guide chambers. This prevents dirt, such as glue and dust, from entering the guide chambers of the clamping frame profiles.Preferably, the piping and / or the blind piping is formed from a rubber material. The piping and / or the blind piping or the rubber material of the piping / blind piping preferably has a maximum modulus of elasticity of 3.5 GPa. A rubber material has a certain flexibility and facilitates the formation of an interference fit with the clamping frame profile and optionally the securing element. A rubber material enables a good coefficient of friction between the piping or blind piping and the clamping frame profile, which in turn has a positive effect on the secure hold of the piping or blind piping in the guide chambers.In a particularly advantageous embodiment of the invention, a backlighting is provided for illuminating the textile plate from behind. Backlighting enables particularly appealing optics, in particular in darkness.Further features and advantages of the large-area advertising panel emerge from the following description of exemplary embodiments, reference being made to the appended drawing.In the drawing, diagrammatically show, in each case, FIG. 1A shows a first exemplary embodiment of a large-area advertising panel according to the invention in an exploded perspective view, FIG. 1B shows the large-area advertising panel from FIG. 1A in a perspective illustration, FIG. 1C shows the large-area advertising panel from FIG. 1A with a textile placard in a perspective illustration, FIG. 1D shows the large-area advertising panel from FIG. 1C in cross section, FIG. 2A shows a second exemplary embodiment of a large-area advertising panel according to the invention in an exploded perspective view, FIG. 2B shows the large-area advertising panel from FIG. 2A in a perspective illustration, FIG. 2C shows the large-area advertising panel from FIG. 2A with a textile placard in a perspective illustration, FIG. 2D shows the large-area advertising panel from FIG. 2C in cross section, FIG. 3A shows a clamping frame profile of the large-area advertising panel from FIG. 2A in cross section in a detailed view, FIG. 3B shows the clamping frame profile from FIG. 3A in cross section in a detailed view with a securing element during assembly, FIG. 3C shows the clamping frame profile from FIG. 3A in cross section in a detailed view with a securing element after assembly, FIG. 4 shows a detailed view of the large-area advertising panel from FIG. 2C during the mounting of the textile plate in a perspective illustration, FIG. 5 shows a third exemplary embodiment of a large-area advertising panel according to the invention in cross section, and FIG. 6 shows the clamping frame profile from FIG. 3A in cross section in a detailed view with a blind wedge.FIG. 1A shows a first exemplary embodiment of a large-area advertising panel according to the invention for external advertising in an exploded perspective view.The large-area advertising panel comprises a panel element 2 for attaching a poster or the like (not shown here), in particular by means of wet adhesive bonding, and front elements 4 arranged circumferentially around the panel element. In addition, the large-area advertising panel has four circumferentially arranged tentering frame profiles 6 for fastening and tensioning a textile poster 8 (not shown here), wherein the tentering frame profiles 6 each have a guide chamber 26 for receiving a piping 12. Furthermore, a clamping frame 14 is provided which can be fastened to the panel element 2 by means of holding brackets 16. The clamping frame profiles 6 can be mounted on the panel element 2 via the clamping frame 14. The tenter frame 14 is formed by four rectangular tubes 18 connected to one another. The tenter profiles 6 and the rectangular tubes 18 are formed from extruded profiles, in particular from extruded aluminum profiles made of an AlMgSi alloy.Retrofitting a classic large-area advertising board, which is suitable only for the attachment of a poster or the like, for example by means of wet adhesive bonding, can be retrofitted with little effort, as described above, in order also to enable an attachment and tension of a textile poster 8 alternatively to the attachment of a poster on the board element 2. Specifically, for retrofitting, only the clamping frame 14 has to be screwed onto the panel element 2 by means of angle brackets 16 and the clamping frame profiles 6 have to be fastened circumferentially to the clamping frame 14, for example by means of screws.FIG. 1B shows the large-area advertising panel from FIG. 1A in a perspective illustration.FIG. 1C shows the large-area advertising board from FIG. 1A with a textile placard 8 in a perspective illustration. The textile pallet 8 has an area of at least 8 m 2 wherein the textile pallet 8 has in particular a motif in a size of 3.56 m×2.52 m.FIG. 1D shows the large-area advertising panel from FIG. 1C in cross section, wherein the encircling clamping frame profiles 6, the front elements 4, the clamping frame 14 and further encircling elements are of substantially identical configuration in cross section. It can be seen that the clamping frame 14 is formed by four rectangular tubes 18 connected to one another, on 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 brackets 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 encircling front elements 4 are attached to the panel element 2 via adapter profiles 24.The clamping frame profiles 6 each have a guide chamber 26. The guide chamber 26 is substantially rectangular in cross section. The textile pallet 8 has a circumferential piping 12 which is arranged in the guide chamber 26 of the tenter frame profile 6. The piping 12 is attached to the back side of the textile plate 8 and is also formed substantially rectangular in cross section.The guide chamber 26 of the tentering frame profiles 6 has an opening 28 in cross section, through which the piping 12 of the textile plate 8 can be introduced.The guide chamber 26 is open toward the front, so that the opening 28 extends on the front side of the tenter frame profiles 6 directed toward the textile poster 8. The opening 28 of the guide chamber 26 serves not only for an opening for the textile pallet 8 but also as an opening for inserting the piping 12 from the front. Accordingly, the piping 12 does not have to be inserted into the guide chambers 26 at the lateral ends of the clamping frame profiles 6, but can be inserted into the guide chambers 26 from the front. This facilitates the mounting of the textile plate 8 on the large-area advertising board.The clamping frame profiles 6 have, in cross section at their guide chambers 26 in the region of the opening 28, a barb-shaped section 30 for retaining 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 encircling front elements 4. The barbed section 30 is formed by a substantially rectangular section which holds the substantially rectangular piping 12 of the tensioned textile plate 8, in particular in difficult weather conditions, for example a large amount of wind, in the guide chamber 26.Next to the piping 12, a securing element 32 is arranged in the guide chamber 26. The securing element 32 serves for securing the piping 12 in the guide chamber 26, the securing element 32 abuts an inner side of the guide chamber 26 assigned to the encircling front elements 4 and prevents the piping 12 from moving upwards in the cross section shown in FIG. 1D in the direction of the opening 28.The piping 12 is formed of a rubber material, while the securing member 32 is made of a plastic or a 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 a press fit is formed between the securing element 32, piping 12 and the clamping frame profile 6 in the end position. The securing element 32 has an Young's modulus of at least 5 GPa and a bending strength of at least 120 MPa, while the core 12 has an Young's modulus of at most 3.5 GPa.The securing element 32 is formed as a substantially rectangular plate having a thickness of about 0.7 cm, a height of about 1.5 cm and a width of at least 10 cm. The piping 12 has a thickness of about 3 cm. The opening 28 of the clamping frame profile 6 is designed to be so large 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 plate 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 plate 8 covering the opening 28.In the cross section of the clamping frame profiles 6, the securing element 32 projects beyond the piping 12, as seen toward the opening 28, which simplifies the extraction of the securing element 32 from the guide chamber 26 in the event of a motif change.FIGS. 2A-D show a perspective view of a second exemplary embodiment of a large-area advertising panel according to the invention. In contrast to the exemplary embodiment shown in FIGS. 1A-1D, no clamping frame is provided for fastening the clamping frame profiles. In the case of the large-area advertising panel depicted in FIGS. 2A-D, the clamping frame profiles 6' are fastened directly to the encircling front elements 4.The fastening of the clamping frame profiles 6' to the encircling front elements 4 can be seen in particular in the cross section depicted in 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.In this embodiment too, retrofitting a classic large-area advertising board, which is suitable only for attaching a poster on the panel element 2', to a large-area advertising board, to which a textile poster can likewise be fastened and tensioned, is easily possible. For retrofitting, only four clamping frame profiles 6' have to be screwed circumferentially to the inner sides of the front elements 4. As an alternative to the screw connection, the clamping frame profiles 6' can also be adhesively bonded to the front elements 4.In FIGS. 3A-3C, the tenter frame profile 6' of the large-area advertising panel from FIG. 2A is illustrated 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 firstly the piping 12 is inserted into the guide chamber 26' from the front and is hooked in behind the hook-shaped section 30' of the tenter frame profile 6'. Subsequently, the securing element 32 can likewise be inserted through the opening 28', so that the piping 12 is fixed in the guide chamber 26' of the tenter frame profile 6'. In the assembled state, the piping 12 bears against the inner side of the guide chamber 26' facing away from the front elements 4, while the securing element 32 bears against the inner side of the guide chamber 26' facing the front elements 4.In the detailed view, it can be seen that the guide chamber 26' of the tenter frame profile 6' has inwardly directed projections 34' on its inner sides, wherein the projections 34' are arranged on opposite sides of the guide chamber 26'. The projections 34' have a partially circular cross-section shape with a height of 0.25 mm, wherein 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'.The piping 12 is formed from an elastic material, so that the projections 34' can press into the material of the piping 12 and hold it firmly in the guide chamber 26' of the tenter frame profile 6', so that the risk of the piping 12 slipping out of the guide chamber 26' is reduced even under demanding weather conditions. Since the projections 34' are arranged on opposite sides of the guide chamber 26', the friction increases from several sides, which has a particularly positive effect on the fixing of the piping 12 in the guide chamber 26'.FIG. 4 shows a detailed view of the large-area advertising panel from FIG. 2C during the assembly of the textile plate 8 in a perspective illustration. It can be seen how the piping 12 fastened on the rear side of the textile board 8 is inserted into the guide chamber 26' of the tenter frame profile 6' from the front. After the piping 12 has been introduced into the guide chamber 26', a plurality of circumferentially arranged securing elements 32 can be inserted through the opening 28' of the tenter profile 6' into the guide chamber 26' of the tenter profile 6', so that the piping 12 of the textile board 8 is held particularly firmly in the guide chamber 26'. The mounting of the securing elements 32 is indicated by a securing element 32 shown in dashed lines and an arrow.Two securing elements 32 are arranged in each corner region of the large-area advertising panel. 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, preferably uniformly (with the exception of the securing elements 32) arranged in the corner regions. It can be seen that the securing elements 32 are designed as 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'.FIG. 5 shows a cross section of a third exemplary embodiment of a large-area advertising panel according to the invention. The third exemplary embodiment, like the second exemplary embodiment, shows a variant in which the encircling clamping frame profiles 6'' are fastened to the encircling front elements 4''. The fixing of the circumferentially arranged clamping frame profiles 6'' to the circumferentially arranged front elements 4'' can be effected via an adhesive connection, a screw connection or the like.FIG. 6 shows the tenter profile 6' from FIG. 3A in cross section in a detailed view with a blind wedge 36 which can be arranged alternatively to the wedge 12 of the textile plate 8 in the guide chamber 26' of the tenter profile 6'. The blind wedge 36 can be used if the large-area advertising board is customarily managed with a poster on the panel element 2 and no textile poster 8 is mounted on the large-area advertising board.As indicated by the dashed line, the blind core 36 is pushed through the opening 28' of the tenter frame profile 6' from the front into the guide chamber 26' of the tenter frame profile 6'. The blind wedge 36 has a stop 38 which, in the assembled state, abuts a section of the tenter frame profile 6' and prevents the blind wedge 36 from sliding too far into the guide chamber 26' and being able to be pulled out of the guide chamber 26' again and again well.The blind core 36 is formed to close the opening 28' of the guide chamber 26'. This prevents dirt, such as glue and dust, from entering the guide chambers 26' of the tenter frame profiles 6'.The blind core 36 is formed of a rubber material and has a certain elasticity. The rubber material of the blind cedar has a modulus of elasticity of at most 3.5 GPa. This readily allows the formation of an interference fit by compressing blind core 36 when inserted through opening 28' into guide chamber 26'. In addition, the rubber material enables a good coefficient of friction between blind piping 36 and clamping frame profile 6', which in turn has a positive effect on the secure retention of blind piping 36 in guide chamber 6'. The blind core 36 advantageously has substantially the same length as the corresponding clamping frame profile 6', so that the clamping frame profile 6' is closed from the front over the entire length.The explanations concerning the hook-shaped section 30', the projections 34', the blind wedge 36 and the securing element 32 also apply analogously to the exemplary embodiments depicted in FIGS. 1A-1D and 5.2, 2', 2" panel element 4 front element 6, 6', 6" tenter frame profile 8 textile post 12 piping 14 tenter frame 16 holding bracket 18 rectangular tube 20 screw 21, 21' screw channel 22 screw 24, 24' adapter profile 26, 26', 26" guide chamber 28, 28', 28" opening 30, 30' barb-shaped section 32 securing element 34' projection 36 blind piping 38 stop
