Description

Device for mounting a poster,

Poster clamping arrangement and tools for mounting a

Poster on a poster chuck

The invention relates to a device for mounting a poster, especially a large-format poster in the outdoor area. Furthermore, the invention relates to a poster mounting arrangement, comprising such a device and a poster with a piped edge, and an aid for mounting a poster on a poster clamping device.

For mounting large-format plastic posters outdoors, stable frame constructions are used. Such frame structures have an internally circulating, typically designed as a tube clamping abutment to which the poster is connected with expander ropes. For this purpose, eyelets are inserted into the reinforced edge of the poster, through which the expander rope or cables are led. The power required to hold the poster results from the restoring force of the expander ropes. Such frame structures can also be designed as so-called lifters, in which an upper transverse profile is pulled up by means of a pulling device for mounting the poster on a guide of the frame. The connection of a poster to such a frame construction with or without lifter designed as a result of the necessary Einfädeins the expander ropes as time-consuming. Such frame structures are therefore in principle not suitable for mounting posters, which are to be changed more often. Moreover, the eyelets used to prevent tearing of the expander ropes pulled through the poster appear. This is sometimes undesirable.

In addition to the above-described frame constructions Kederprofilkonstruktionen be used for mounting posters in the outdoor area. The poster itself must have a welt edge for this purpose, which must be pulled into a welt groove of a frame profile. Also in this concept, the mounting and replacing a poster is expensive.

In addition to these prior art poster clamping devices, nenbereich also used those in which the edge of the poster wearing a piping tape, which is pressed into a circumferential groove of a frame for mounting the poster. The central longitudinal plane of the circumferential groove of the frame profile is aligned perpendicular to the plane aufzuspan- to the poster. In such poster clamping devices, it is necessary that the poster to be spread is provided very accurately assembled. In these posters, the clamping force resulting from the plastic material used for the poster itself. As a poster fabric therefore preferably a fine-meshed network is used. Due to the wind loads acting on such a poster in the outdoor area, in particular if such a poster is large-format, a clamping system for holding a poster equipped with a piping tape edge can not be used. Silicone piping tapes are typically used in these systems, with the thickness of the edge of the poster together with the piping strip being greater than the inside width of the connecting groove of the frame profile (s). This serves the purpose that the inserted into such a connection groove edge of the poster is frictionally held therein. The achieved frictional engagement determines the pull-out force that is needed to pull the poster with its piping edge of such a connection groove can. The edge of such a poster is manual is to press in the connecting groove of the profile. This requires careful work and is powerful and time consuming. However, the frictional engagement achieved in this way is not sufficient, so that this is sufficient to withstand the outside wind loads.

Based on the pre-discussed prior art, the present invention seeks to propose a Plakataufspannvorrichtung and a Plakataufspannanordnung with such a poster chuck, which is particularly suitable for outdoor use and in the clamping of a poster or changing a poster to previously known, for the Outdoor used Posterspannspannvorrichtungen is improved. Furthermore, the invention has for its object to propose an aid for facilitating the Aufspannens and also changing a poster of such a poster clamping device.

This object is achieved by a device for mounting a Poster, especially a large-format poster in the outdoor area with the features of claim 1.

In this poster jig pairwise opposite clamping profiles for mounting the poster are provided. The clamping profiles thus represent a clamping frame on which a poster can be kept stretched.

To connect the poster to the clamping profiles, these each have at least one of their longitudinal extension following connection groove. The connecting groove is arranged such that the mouth of the same points in one of the other clamping profile of the clamping profile pair and thus in a direction away from the billboard direction. The central longitudinal plane encloses an angle of less than 90 ° with the poster plane. In this way, depending on the embodiment, a Umlegkante or a Umlegkantenanordnung is formed around which must be performed in the connection groove to be inserted edge of the poster, so that the thickened edge of the poster can be inserted into the connecting groove. To insert the edge of the poster into the connection groove, the latter must therefore be folded over more than 90 ° with respect to the plane of the printed poster. The piping tape used in such a connection groove then encloses an acute angle with the plane of the profile. Wind loads acting on the poster, which lead to movements, for example perpendicular to the poster plane, do not have the consequence in this design that the edge of the poster introduced into the connecting groove is pulled out of this poster. Thus it turns out unexpectedly that the previously used exclusively in interior piping edge design under the conditions mentioned in the outdoor area is used. In addition, in order to maintain the connection of the paw katrand to the clamping profiles, it is generally not necessary for the poster edge with its piping strip to be held with greater clamping forces in the connecting groove of a clamping profile. Rather, it is possible to use as Paspelband also stiffer, less compressible and less expensive materials than silicone, for example, PVC piping, which are held only with little or no clamping force in the connection groove. When applying a tensile load on the poster they wedge within the connection groove. This possibility allows - A -

the connection of a poster edge to a tension profile without much effort and in principle in a shorter time. The same applies to changing a poster.

To improve a jamming of the piping tape with the poster edge connected thereto in a connecting groove, the latter carries one or more Verklammerungswülste projecting into the groove, the longitudinal extent of such a clamping profile following. Similarly, the piping tape may have such Verklammerungswülste. This is particularly suitable for PVC piping tapes or piping tapes made of a corresponding material. By such Verklammerungswülste a wedging is achieved by bringing about a positive connection of Paspelbandes within the connecting groove in case of a tensile load on the poster. In the longitudinal extension of the clamping profile and thus in the longitudinal extent of a connecting groove, the piping belt, however, remains movable in the connecting groove. This is useful in the use of non-elastic poster materials, since then tensioning of the poster by the clamping profiles is not hindered by the Paspelbandanschluss the poster edge in such a connection groove. Especially with large posters is a certain longitudinal displacement of the engaging in the connecting groove edge of the poster with the attached piping tape for uniform tensioning of the poster is not insignificant.

In such a poster clamping device is preferably at least one of two, each with respect to the aufzuspannenden poster opposite clamping profile relative to the other toward the other against the force of one or more return elements, such as springs or spring elements movable. A tensioning of the aufzusaufendes poster thus takes place when using springs as restoring elements, at least also with the participation of the spring-loaded clamping profiles. Therefore, this jig is also suitable for those posters that have no material or no appreciable elasticity due to the material. Such a material property is desirable in particular for posters which hang only for a short time, since then a cost-effective plastic carrier web can be used as a poster base. According to one embodiment, all the clamping profiles in the manner described above relative to the other clamping profile of a clamping profile pair against the force of one or more restoring elements, in particular spring elements movably mounted. Depending on the length of such a clamping profile, this is held in two or more such bearings.

Further advantages and embodiments of the invention will become apparent from the following description of an embodiment of the invention with reference to the accompanying figures. Show it:

A device for mounting, in particular, a large-format poster - a poster clamping device 1 - has two clamping profile pairs. The two clamping profiles 2, 2.1 and 3, 3.1 of the two clamping profile pairs are arranged opposite each other with respect to the poster to be spread. Are held the clamping profiles 2, 2.1, 3.3.1 via bearings on which they are translationally movable. The bearings themselves are connected to a base plate 4 and are described below. Framed is the arrangement of a rectangular clamping frame forming clamping profiles 2, 2.1, 3, 3.1 by a frame. 5

The clamping profiles 2, 2.1, 3, 3.1 are each similar to each other and differ in their length in order to achieve the rectangular geometry of the clamping frame, as seen in Figure 1, to achieve. The storage of the individual clamping profiles 2, 2.1, 3, 3.1 is identical. Each clamping profile 2, 2.1, 3, 3.1 is held by two bearings. In the following, the bearing designated by the reference numeral 6 in FIG. 1 is described in more detail. The remaining bearings are equally designed. The bearing 6 has a U-shaped basic body 7 made of metal (see also FIG. 2). Between the two legs 8, 8.1 of the main body 7, a guide pin 9 extends with a circular cross-sectional area. The guide pin 9 is rigidly held in the legs 8, 8.1 of the main body 7. The tensioning profile 2 is thus translationally movable in the direction of the longitudinal extent of the guide pin 9 relative thereto, as indicated schematically by the block arrows in FIG. The inside guide boundary is formed by the leg 8 in the illustrated embodiment. By this is the clamping profile 2 in the illustrated embodiment, as seen from Figures 1 and 2, held spaced from the other clamping profile 2.1 of this clamping profile pair in its normal position. Can be moved, the clamping profile 2 against the force of the helical compression spring 10 in the direction of the clamping profile 2.1, whereby the distance between the two clamping profiles 2, 2.1 reduced each other. The main body 7 is in a manner not shown on the base plate 4 attached, for example by means of screws or rivets.

In the clamping profile 2 of the illustrated embodiment is an extruded profile of an aluminum alloy. The cross-sectional area of the clamping profile 2 can be seen in FIG. The clamping profile 2 has an approximately square cross-sectional area. The of the two legs 8, 8.1 connecting the bottom 11 of the main body 7 of the bearing 6 pioneering side of the clamping section 2 is located at a greater distance to the bottom 1 1 as the outer end of the legs 8, 8.1. This outside of the clamping profile 2 is indicated in Figure 2 by the reference numeral 12. On the outside 12 is a aufzuspannendes to the Plakataufspannvorrichtung 1 poster after mounting the same. Thus, the outer side 12 of the clamping profile 2 forms the poster plane of a spanned on the clamping frame poster.

The clamping profile 2 has several grooves. One of these grooves, namely a connection groove designated by the reference numeral 13, is used to receive a provided with a piping edge of a poster. The connecting groove 13 has with its mouth in one of the other clamping profile 2.1 of this clamping profile pair pioneering direction. At the same time, the mouth of the connecting groove 13 also knows about the poster surface located between the clamping profiles 2, 2.1. In the illustrated embodiment includes the central longitudinal plane M of the connecting groove 13 with the outside 12 of the clamping profile 2 and thus with the poster plane an angle a of 45 °. The formation of the connection groove 13 and its spatial position to the outside 12 requires that a to be connected to the clamping profile 2 edge portion of a poster from the plane of the poster, represented by the outside 12, at the Umlenkkante U must be folded by 135 ° in order to Connection groove 13 can be introduced. The Umlegekante U is formed by the adjacent outer side 12 and the adjoining groove wall 14 (see Figure 2a). If the edge of the poster is inserted into the groove arranged parallel to the connecting groove 13, the transfer edge U together with the apex forms the connecting groove 13 of the adjacent groove separating web a Umlegekantenanordnung.

The connecting groove 13 has two parallel groove walls 14, 14.1. Out The enlarged representation of the connecting groove 13 shown in FIG. 2 a shows that a respective crimping bead 15, 15. 1 is projecting from the groove walls 14, 14. 1 into the groove 13. The Verklammerungswülste 15, 15.1 are offset from one another, wherein the integrally formed on the groove wall 14 Verklammerungswulst 15 is disposed closer to the mouth of the connecting groove 13. The Verklammerungswülste 15, 15.1 serve the purpose that an inserted into the connecting groove 13 edge portion of a poster, equipped with a piping tape, can be kept positively clamped therein.

In order to clamp a poster 16 on the poster clamping device 1, the latter has a piping band 17 attached peripherally at its edge. The piping tape 17 is a PVC tape in the illustrated exemplary embodiment, which is connected to the poster 16, for example by sewing. Other connection techniques, such as sticking, are also possible. The piping 17 carries on its side facing away from the poster 16 side a plurality of mutually parallel and the longitudinal extent of the piping tape 17 following beads 18. These act when used in the connection groove 13, together with the Verklungsungswulst 15 to create the desired form fit.

If the poster 16 with its piping edge edges is inserted in each case into the connecting groove 13 of the clamping profiles 2, 2.1, the arrangement shown in FIG. 3 results. The two clamping profiles 2, 2.1 have been moved toward each other against the force of the respective helical compression springs 10. Thus, the helical compression springs 10 of the bearings of the two clamping profiles 2, 2.1 act against each other and keep the poster 16 to tension. It can clearly be seen in FIG. 3 that the poster edge with the piping tape 17 had to be folded over by 135 ° so that the piping edge can be inserted into the respective connecting groove 13. During assembly, ie when inserting the Paspelbandrandes the poster 16, the clamping profiles 2, 2.1 are each in the region of the inside stop of the respective bearing 6. If the Paspelbandrand inserted into the connection groove 13, the respective profile 2 or 2.1 released, which as a result of the restoring force of the helical compression springs 10, the poster 16 is stretched when this already with its opposite edge to the further clamping profile of the clamping profile pair is connected.

As a result of the orientation of the connecting grooves 13, flapping movements of the poster 16 do not result in the piping strip edge being pulled out of a connecting groove 13. Rather, the piping strip edge is adjusted in each connecting groove 13 at elevated tensile load, so that it is wedged and held by the cooperating Verclammerungswülste 15, 18 form fit therein. To aid this moment, piping tapes are typically used that have some rigidity, such as that typical of a PVC piping tape. Because of this clamping by adjusting within the respective connecting groove 13, the piping strip edge can sit relatively loosely in a connecting groove 13 without a tensile load acting thereon and therefore be correspondingly easily assembled and disassembled. The necessary tensile load for adjusting or pinching the Paspelbandrandes in the connection groove 13 is caused by the two clamping profiles 2, 2.1 and 3, 3.1 of a clamping profile pair of mutually wegdrückenden helical compression springs 10, whereby the poster 16 is stretched towards its edges , It is understood that the dimensioning of the poster to be tensioned on the distance of the mouths of the connecting grooves 13 of the opposing clamping profiles 2, 2.1; 3, 3.1 is tuned, in such a way that the helical compression springs 10 are biased by the spanned poster, thus the clamping profiles of the outer leg (in the clamping profile 2 of the legs 8.1 of the bearing 6) is moved away (see also Figure 5) ,

The Verklammerungswülste 18 of Paspelbandes 17 favor a longitudinal displacement of the inserted into a connecting groove 13 Paspelbandrandes the poster 16. This is desired so that the poster 16 can be stretched in all directions and such clamping not by an inserted into a connecting groove 13 Paspelband including edge portion of the Poster 16 is disabled.

FIG. 4 shows the poster clamping device 1 of FIG. 1 with the poster 16 spanned on the clamping profiles 2, 2.1, 3, 3.1. Since the clamping profiles

2, 2.1, 3, 3.1 lie behind the visible side of the poster 16, these are in

Figure 4 shown by dashed lines. The frame 5 is merely an optical Beautification of the Poster Clamping Device 1. As can be seen from FIG. 4, the clamping profiles 2, 2.1, 3, 3.1 are moved away from the respectively outer leg of their respective bearing in the direction of the further clamping profile of the respective clamping profile pair. This can be better seen in an enlarged representation in FIG. 5, in which the poster 16 is shown torn open in the region of the bearing 6. Clearly recognizable as well as from Figure 3, the cocked position of the helical compression spring 10th

The description of the above embodiment makes it clear that wind loads are absorbed by the compression springs of the bearing of the clamping profiles. This prevents fluttering of the poster when exposed to wind, so that in this respect otherwise occurring damage is at least largely avoided. In the illustrated embodiment, the base plate located behind the spanned poster also represents a support in wind exposure to the poster, so that this can be dented in its central region maximum up to the plane of the base plate in wind-induced. The resilient mounting of the clamping profiles ensures an automatic tensioning of the poster even with decreasing wind load.

FIG. 6 shows the poster clamping device 1 of FIG. 4 with the only partially loaded poster 16 and an aid 19 used to clamp the poster 16. The aid 19 serves to simplify the mounting of a poster, for example, of the poster 16 or else to remove it. The Aufspannhilfsmittel 19 has a roller holder 20, which is designed in the illustrated embodiment as a roller rod. The roll holder 20 has at its lower end on a plate 21, on which a aufzuspannende the poster 16 carrying roll core 22 stands up. The roller holder 20 designed as a roller bar is connected to a guide carriage 23, which can be moved in the horizontal direction and thus parallel to the longitudinal axis of the poster clamping device 1, parallel to the plane of the opened poster. The carriage 23 has two roller assemblies 24, 25 (see Figure 7). The roller assembly 24 is held in a guide rail 26 located above and behind the frame 5. The roller assembly 25 is supported on the front of the frame 5. The carriage 23 and the upper end of the roller holder 20 have over complementary connecting elements, so that the roller holder 20 can be connected to the guide carriage 23 like a bayonet.

With a thus conceived tool 19, the clamping and also changing a poster on the Plakataufspannvorrichtung 1 is not insignificantly simplified and can be performed in particular by a single person in a short time. In this case, the assembly and disassembly process is supported by the conception of the intervention of the piping tape edge of the poster in the manner described in the clamping profiles.

The Aufspannhilfsmittel 19 described in Figures 6 and 7 can also be used independently of the above-described Posteraufspannvorrichtung 1 for mounting or hanging a poster on differently designed jigs.

FIG. 8 shows a further tensioning profile 27, which differs from previously described tensioning profiles 2, 2.1; 3, 3.1 differs in terms of its cross-sectional geometry. The clamping profile 27, like the previously described clamping profiles, has a connecting groove 28 which has the same orientation or spatial position as the connecting groove 13 of the prestressing clamping profiles described above. Thus, the central longitudinal plane of the connecting groove 28 with the plane of the outside of the clamping profile 27 includes an angle of 45 °. An edge of the poster 16 equipped with a piping band is inserted into the connecting groove 28.

The tension profile 27 is a profile (frame profile) as described in DE 20 2008 014 694 U1. Through these explicit references, the disclosure content of this document, especially with regard to the backlighting arrangement described therein, is made the subject matter and thus also the disclosure content of this application. With the clamping profiles 27, as described in DE 20 2008 014 694 U1, also large-format posters are backlit. It is understood that when forming a clamping frame, as described with respect to the preceding figures using clamping profiles according to Figure 8, only the pointing to the poster level legs in the form described in DE 20 2008 014 684 U1 and shown in Figure 8 must be inclined in order to achieve a reaching to the Umlenkkante backlight.

The use of a clamping frame, with the clamping profiles suspended as described against the force of restoring elements that greater tolerances can be tolerated in the production of the billboard due to the yielding adjustability of the clamping profiles.

The invention has been described with reference to an embodiment. Without departing from the scope of the claims, numerous other embodiments for a person skilled in the art will be able to realize the invention without this having to be explained in detail in the context of these statements.
